Abstract Lycium ruthenicum Murray (LR) represents an agricultural cash crop found in Northwest China and has been used in traditional folk medicine for a long time. However, detailed qualitative and quantitative analyses of LR anthocyanins, as well as their pharmacological research, remain scarce. In this work, we established a rapid method for the simultaneous identification and quantification of six anthocyanidins and six anthocyanins from LR via UPLC-quadrupole-Orbitrap mass spectrometry (UPLC-Q-Orbitrap MS) analysis. Finally, five anthocyanidins and five anthocyanins were qualitatively and quantitatively analyzed. Among these, 10 constituents (delphinidin-3-glu, cyanidin-3-glu, petunidin-3-glu, peonidin-3-glu, malvidin-3-glu, delphinidin, cyanidin, petunidin, pelargonidin and malvidin) were detected and petunidin-3-glu proved to be the predominant species in LR. Furthermore, the anti-inflammatory effects of anthocyanin extracts and petunidin-3-glu were investigated using a rat model involving gouty arthritis induced by monosodium urate. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-18 (IL-18), prostaglandin E2 (PE2), cyclooxygenase-1 (COX-1) enzymes in serum, the paw COX-1 mRNA expression and paw volume could be determined to be significantly increased in rats suffering from gouty arthritis induced by monosodium urate. However, these indicators were found to be significantly reduced after treatment with anthocyanin extracts (200 mg/kg b.wt, p.o.) and petunidin-3-glu (40 mg/kg b.wt, p.o.). Taken in concert, our study shows that anthocyanin extracts and petunidin-3-glu may significantly reduce monosodium urate crystal-induced inflammation. Use and administration of these compounds may be potentially valuable for the further development and clinical applicability of the active compounds in this plant.
Lycium ruthenicum Murr. (LR) is a perennial shrub commonly used as a nutritional food and medicine. Herein, we identified 12 anthocyanins from LR, with petunidin derivatives constituting approximately 97% of the total anthocyanin content. Furthermore, the potential mechanism of anthocyanins exerting neuroprotective effects in d-galactose (d-gal)-treated rats was explored. Behavioral results showed that anthocyanins relieved d-gal-induced memory disorder. Additionally, anthocyanins reduced receptor for advanced glycation end products (RAGE) and suppressed oxidative stress caused by d-gal. Anthocyanins suppressed microgliosis and astrocytosis and reduced the overexpression of nuclear factor kappa B (NF-κB), interleukin-1-β (IL-1β), cyclooxygenase-2 (COX-2), and tumor necrosis factor-α (TNF-α). Moreover, anthocyanins lowered C-jun N-terminal kinase ( p-JNK), caspase-3 levels, and the B-cell lymphoma 2-associated X protein/B-cell lymphoma 2 (Bax/Bcl-2) ratio. Thus, anthocyanins from LR attenuated memory disfunction, neuroinflammation, and neurodegeneration caused by d-gal, possibly through the RAGE/NF-κB/JNK pathway, representing a promising, safe candidate for prevention and therapy of neurodegenerative diseases.
In this paper, an efficient method was successfully established by the combination of macroporous resin (MR) and high-speed counter-current chromatography (HSCCC) for rapid enrichment and separation of aloe-emodin 8-O-β-D-glucoside, emodin 1-O-β-D-glucoside, emodin 8-O-β-D-glucoside and piceatannol 4'-O-β-D-(6″-O-gallate)-glucoside. Six kinds of macroporous resins were investigated in the first step and X-5 macroporous resin was selected for the enrichment of the target compounds. The recoveries of the target compounds reached 89.0, 85.9, 82.3 and 84.9% respectively after 40% ethanol elution. In the second step, the target compounds were separated by HSCCC with a two-phase solvent system composed of chloroform/ethyl acetate/methanol/water (8:1:6:5, v/v). The established method will be helpful for further characterization and utilization of Rheum tanguticum. The results demonstrate that MR coupled with HSCCC is a powerful technique for separation of bioactive compounds from natural products.
Humans have a close relationship with nature, and so integrating the nature world into indoor space could effectively increase people's engagement with nature, and this in turn may benefit their health and comfort. Since people spend 80-90% of their time indoors, the indoor environment is very important for their health. Indoor plants are part of natural indoor environment, but their effect on the indoor environment and on humans has not been quantified. This review provides a comprehensive summary of the role and importance of indoor plants in human health and comfort according to the following four criteria: photosynthesis; transpiration; psychological effects; and purification. Photosynthesis and transpiration are important mechanisms for plants, and the basic functions maintaining the carbon and oxygen cycles in nature. Above all have potential inspiration to human's activities that people often ignored, for example, the application of solar panel, artificial photosynthesis, and green roof/facades were motivated by those functions. Indoor plants have also been shown to have indirect unconscious psychological effect on task performance, health, and levels of stress. Indoor plants can act as indoor air purifiers, they are an effective way to reduce pollutants indoor to reduce human exposure, and have been widely studied in this regard. Indoor plants have potential applications in other fields, including sensing, solar energy, acoustic, and people's health and comfort. Making full use of various effects in plants benefit human health and comfort.
ObjectiveThis study investigates the breathing frequency (BF)-independent effect of Tai Chi Chuan (TCC) on autonomic nervous modulation in TCC practitioners.MethodsTwenty-five TCC practitioners and 25 sedentary normal controls were recruited. The stationary heart rate variability (HRV) measures of TCC practitioners and controls were compared. The same HRV measures in TCC practitioners and among the controls, TCC practitioners before TCC and TCC practitioners 30 min after TCC were compared.ResultsIn TCC practitioners, the BF, normalized high-frequency power (nHFP), and normalized very low-frequency power were significantly increased, while the normalized low-frequency power (nLFP) was significantly decreased 30 min after TCC. The BF correlated significantly and negatively with heart rate (HR), nHFP and nLFP, and correlated significantly and positively with mean RR interval (MnRR) before TCC in TCC practitioners. A slower BF is associated with a higher HR, a greater vagal modulation, and a greater combined sympatho-vagal modulation before TCC. To remove the effect of BF on HRV measures, new indices such as HR*BF, nHFP*BF, nLFP*BF, and MnRR/BF were introduced for comparison among the controls, TCC practitioners before TCC, and TCC practitioners 30 min after TCC. Thirty minutes after TCC, the MnRR/BF of TCC practitioner was smaller whereas HR*BF and nHFP*BF were greater than those before TCC.InterpretationThe BF-independent effects of TCC on the autonomic nervous modulation of TCC practitioners are an increase in vagal modulation and HR, and a decrease in mean RR interval. The mechanism underlying the parallel increase in HR and vagal modulation in TCC practitioners is not understood yet at present.
Background: Meditation refers to a group of practices commonly proposed to treat stress-related conditions and improve overall wellness. In particular, meditation might exert beneficial actions on heart rate variability (HRV) by acting on autonomic tone with an increase in the vagal activity. The effects of heartfulness meditation (HM) on HRV remain poorly defined. Methods: We investigated the effects of HM on HRV in a group of 26 healthy subjects. Subjects were regularly practicing this form of meditation on a daily basis. We assessed the HRV and residual HRV (rHRV) at rest and during meditation. We also used as control a period of respiratory rhythm imposed by an auditory signal, with the imposed breathing rhythm being identical to the spontaneous rhythm recorded during meditation. Results: During deep meditation period, the standard deviation of RR intervals (SDRR), coefficient of variation of RR intervals (CVRR), and total power (TP) were decreased while the low-frequency power (LFP), normalized LFP (nLFP), and normalized residual LFP (nrLFP) were increased as compared with those at rest, suggesting that the global vagal modulation was suppressed while the baroreflex was increased during deep medication. At the end of meditation, the LFP, residual LFP (rLFP), nLFP, nrLFP, low-/high-frequency power ratio (LHR), and residual LHR (rLHR) were increased while the residual very low-frequency power (rVLFP), normalized high-frequency power (nHFP), and normalized residual HFP (nrHFP) were decreased, as compared with those during paced breathing, suggesting that the vagal modulation was decreased while the sympathetic modulation was increased by deep meditation. During paced breathing period, the SDRR, CVRR, TP, LFP, rLFP, nLFP, nrLFP, LHR, and rLHR were decreased while nHFP and nrHFP were increased as compared with at rest, suggesting that paced breathing could suppress the sympathetic modulation and enhance the vagal modulation. Conclusion: HM can induce a suppression of global vagal modulation and increased the sympathetic modulation and baroreflex. In addition, paced breathing can suppress the sympathetic modulation and enhance the vagal modulation. Unlike studies using other types of meditation, we did not identify evidence of increased vagal tone during HM.
Answer questions and earn CME/CNE Patients with breast cancer commonly use complementary and integrative therapies as supportive care during cancer treatment and to manage treatment-related side effects. However, evidence supporting the use of such therapies in the oncology setting is limited. This report provides updated clinical practice guidelines from the Society for Integrative Oncology on the use of integrative therapies for specific clinical indications during and after breast cancer treatment, including anxiety/stress, depression/mood disorders, fatigue, quality of life/physical functioning, chemotherapy-induced nausea and vomiting, lymphedema, chemotherapy-induced peripheral neuropathy, pain, and sleep disturbance. Clinical practice guidelines are based on a systematic literature review from 1990 through 2015. Music therapy, meditation, stress management, and yoga are recommended for anxiety/stress reduction. Meditation, relaxation, yoga, massage, and music therapy are recommended for depression/mood disorders. Meditation and yoga are recommended to improve quality of life. Acupressure and acupuncture are recommended for reducing chemotherapy-induced nausea and vomiting. Acetyl-L-carnitine is not recommended to prevent chemotherapy-induced peripheral neuropathy due to a possibility of harm. No strong evidence supports the use of ingested dietary supplements to manage breast cancer treatment-related side effects. In summary, there is a growing body of evidence supporting the use of integrative therapies, especially mind-body therapies, as effective supportive care strategies during breast cancer treatment. Many integrative practices, however, remain understudied, with insufficient evidence to be definitively recommended or avoided. CA Cancer J Clin 2017;67:194-232. (c) 2017 American Cancer Society.
BACKGROUND: The majority of breast cancer patients use complementary and/or integrative therapies during and beyond cancer treatment to manage symptoms, prevent toxicities, and improve quality of life. Practice guidelines are needed to inform clinicians and patients about safe and effective therapies. METHODS: Following the Institute of Medicine's guideline development process, a systematic review identified randomized controlled trials testing the use of integrative therapies for supportive care in patients receiving breast cancer treatment. Trials were included if the majority of participants had breast cancer and/or breast cancer patient results were reported separately, and outcomes were clinically relevant. Recommendations were organized by outcome and graded based upon a modified version of the US Preventive Services Task Force grading system. RESULTS: The search (January 1, 1990-December 31, 2013) identified 4900 articles, of which 203 were eligible for analysis. Meditation, yoga, and relaxation with imagery are recommended for routine use for common conditions, including anxiety and mood disorders (Grade A). Stress management, yoga, massage, music therapy, energy conservation, and meditation are recommended for stress reduction, anxiety, depression, fatigue, and quality of life (Grade B). Many interventions (n = 32) had weaker evidence of benefit (Grade C). Some interventions (n = 7) were deemed unlikely to provide any benefit (Grade D). Notably, only one intervention, acetyl-l-carnitine for the prevention of taxane-induced neuropathy, was identified as likely harmful (Grade H) as it was found to increase neuropathy. The majority of intervention/modality combinations (n = 138) did not have sufficient evidence to form specific recommendations (Grade I). CONCLUSIONS: Specific integrative therapies can be recommended as evidence-based supportive care options during breast cancer treatment. Most integrative therapies require further investigation via well-designed controlled trials with meaningful outcomes.
Plant-based natural products represent an alternative to chemical compounds for the control of mites in veterinary medicine. Here, the essential oil of Elsholtzia densa (E. densa) Benth was extracted using hydrodistillation at a rate of 1.2%. The chemical composition of the essential oil was determined by gas chromatographymass spectrometry (GC-MS) analysis. The GC-MS analysis indicated that the principal compounds in the volatile oil of the sample were 4-Pyridinol (28.16%) and thymol (26.58%). The acaricidal activity of E. densa oil against Sarcoptes scabiei (S. scabiei) was tested in vitro. Toxicity test data were analysed using a complementary log-log (CLL) model. The E. densa oil was prepared in five concentrations by dilution with liquid paraffin (1, 2, 4, 8 and 16 mg/ml) and exhibited strong toxicity against S. scabiei with LT50 values of 16.637, 5.075, 2.884, 1.184 and 0.760 h, respectively. The LC50 values were 7.678, 4.623, 2.543, 1.502, 1.298 and 0.981 mg/ml for S. scabiei at 1, 2, 4, 8, 16 and 24 h, respectively. Compared to the control, the essential oil showed significant effects against S. scabiei in vitro. At 16 mg/ml, E. densa oil was found to kill all mites within a 16-h period. The results indicate that E. densa oil possesses potential acaricidal activity in vitro and may be exploited as a novel drug for the effective control of S. scabiei. [ABSTRACT FROM AUTHOR]
Complementary and integrative treatments, such as massage, acupuncture, and yoga, are used by increasing numbers of cancer patients to manage symptoms and improve their quality of life. In addition, such treatments may have other important and currently overlooked benefits by reducing tissue stiffness and improving mobility. Recent advances in cancer biology are underscoring the importance of connective tissue in the local tumor environment. Inflammation and fibrosis are well-recognized contributors to cancer, and connective tissue stiffness is emerging as a driving factor in tumor growth. Physical-based therapies have been shown to reduce connective tissue inflammation and fibrosis and thus may have direct beneficial effects on cancer spreading and metastasis. Meanwhile, there is currently little knowledge on potential risks of applying mechanical forces in the vicinity of tumors. Thus, both basic and clinical research are needed to understand the full impact of integrative oncology on cancer biology as well as whole person health. Cancer Res; 76(21); 6159-62. (c)2016 AACR.
In recent years, the term integrative medicine has gained acceptance in medical academia. The Consortium of Academic Health Centers for Integrative Medicine defines this term as "the practice of medicine that reaffirms the importance of the relationship between practitioner and patient, focuses on the whole person, is informed by evidence, and makes use of all appropriate therapeutic approaches, healthcare professionals, and disciplines to achieve optimal health and healing."1 Integrative oncology has been specifically described as both a science and a philosophy that focuses on the complex health of people with cancer and proposes an array of approaches to accompany the conventional therapies of surgery, chemotherapy, molecular therapeutics, and radiotherapy to facilitate health.2 The SIO and its Medline-indexed journal ( Journal of the Society of Integrative Oncology ), founded by leading oncologists and oncology professionals from major cancer centers and organizations, promote quality research and appropriate application of useful, adjunctive complementary modalities (〈http://www.IntegrativeOnc. org〉). The SIO assembled a panel of experts in oncology and integrative medicine to evaluate the current level of evidence regarding complementary therapies in the care of cancer patients. To help health care professionals make evidence-based treatment decisions in integrative oncology, the panel made specific recommendations based on the strength of the evidence and the risks/ benefits ratio. These practice guidelines, developed by the authors and endorsed by the Executive Committee of the SIO, address principles for clinical encounters, followed by individual classes of treatment modalities. There is an essential difference between "complementary" and " alternative" therapies. "Alternative" therapies are typically promoted as a substitute for mainstream care. By definition, alternative therapies have not been scientifically proven, often have no scientific foundation, and have sometimes even been disproved. However, complementary medicine makes use of unconventional treatment modalities and approaches that are nonsurgical and nonpharmaceutical but that have known efficacy. When combined with mainstream care, these modalities can enhance effectiveness and reduce adverse symptoms. The use of complementary and alternative therapies by cancer patients is common, and given that complementary therapies can be helpful in symptom control, but the substitution of therapies with no evidence of safety and/or efficacy can delay or impede treatment, we strongly recommend that medical professionals routinely inquire as to the use of such therapies during the initial evaluation of cancer patients. The extensive use of complementary and alternative therapies can also challenge and frustrate both health care professionals and patients, leading to a gap in communication that negatively affects the patient-provider relationship. This communication gap may also arise from the patient's perception that health care professionals are indifferent to or object to the use of unconventional therapies, a perception that can lead to a loss of trust within the therapeutic bond. Health care professionals, who remain open to inquiries and aware of subtle, nonverbal messages from patients, can create an environment where patients feel free to openly discuss all choices in their care. Evidence suggests that patients supported in this manner are less likely to pursue potentially dangerous alternative therapies and are more likely to adhere to conventional, evidence-based treatment programs. We strongly recommend that qualified professionals provide guidance in an open, evidence-based, and patient-centric manner with those who use or are interested in pursuing complementary or alternative medicine so that they can approach these therapies appropriately. Patients should be informed of the conventional treatment approach, the nature of specific alternative therapies, the realistic expectations, and the potential risks and benefits. © 2009 BC Decker Inc.
PURPOSE: Treatment for head and neck cancer (HNC) results in long-term toxicities and increased physical and psychosocial survivor burden. There are a limited number of treatments for these late effects. Yoga postures, breath work, relaxation, and meditation, may improve these late effects. The purpose of this study was to examine the feasibility of a tailored yoga program in HNC survivors and obtain preliminary efficacy data. METHODS: This was a randomized wait-list control study of yoga-naive HNC survivors who were >3 months post-cancer treatment. Baseline data were collected. Participants were randomized to either an 8-week hatha yoga intervention group or a wait-list group. Feasibility and efficacy data were collected. At 4 and 8 weeks, patients underwent a repeat assessment of health. Wait-list control group participants were offered the yoga program after data collection. Descriptive statistics evaluated feasibility. Mixed effects general linear models were used to generate estimates of the efficacy outcomes. RESULTS: Seventy-three individuals were screened and 40 were eligible. All eligible individuals consented and enrolled. Five of the intervention group discontinued early and none in the wait-list control group. Feasibility was affirmed as participants were recruited and retained in the study, there were no adverse events, fidelity to protocol was demonstrated, and satisfaction rates were high. Efficacy measures indicated potential benefit for shoulder range of motion ( d = 0.57-0.86, P < .05), pain ( d = 0.67-0.90, P </= .005), and anxiety ( d = 0.59, P = .015). CONCLUSION: A tailored hatha yoga program is feasible and potentially efficacious for HNC survivors. Preliminary data supports further investigation of yoga in this population is needed.

Yoga has been shown to improve cancer survivors' quality of life, yet regular yoga practice is a challenge for those who are sedentary. We conducted a pilot randomized controlled study to assess feasibility and adherence of two types of yoga intervention among sedentary cancer survivors. Sedentary breast and ovarian cancer survivors were randomized to practice either restorative yoga (minimal physical exertion, Group R) or vigorous yoga (considerable physical exertion, Group V) in three 60-minute supervised sessions a week for 12 weeks, followed by 12 weeks of home practice. Accrual, adherence, and attendance rates were assessed. Of the 226 eligible patients, 175 (77%) declined to participate in the study, citing time commitment and travel as the most common barriers. Forty-two subjects consented to participate in the study. Of the 35 participants who began the intervention (20 in Group R and 15 in Group V), adherence rate (percentage remaining in the study at week 12) was 100% and 87%, respectively. Rate of adequate attendance (more than 66% of the scheduled supervised sessions) was 85% and 73%, respectively. Rate of completion of the home practice period was 85% and 77%, respectively. In this study, sedentary cancer survivors were able to adhere to a long-term, regular yoga regimen. The rate of adequate attendance was higher for restorative yoga. Future studies for sedentary patients should focus on reducing time commitment and travel requirements to improve recruitment, and on using restorative yoga as a more feasible intervention for this population.
We investigated the psychometric properties of a Chinese version of Five Facet Mindfulness Questionnaire (FFMQ) in a non-clinical student sample. The Chinese FFMQ demonstrated acceptable internal consistency and the test-retest reliability. Confirmatory factor analysis provided support for the five-factor model. Four of these facets (describing, acting with awareness, non-judging and non-reacting) were shown to have incremental validity in the prediction of depression and anxiety. Our findings suggest that the Chinese version of the FFMQ has acceptable psychometric properties and is a valid instrument for the assessment of mindfulness.
Abstract Ethnopharmacological relevance Herpetospermum caudigerum Wall. (HCW) is a traditional Tibetan medicine, which has been used to ameliorate liver injuries in the folk. Aim of the study Liver fibrosis has been recognized as a major lesion of the liver that leads to liver cirrhosis/hepatocarcinoma and even to death in the end. This study aims to demonstrate the protective effect of HCW against CCl 4 -induced liver injury in rats and to explore the underlying mechanisms. Materials and methods Hepatic fibrosis was induced by intraperitoneal injection of CCl 4. Liver function markers, fibrosis markers, serum anti-oxidation enzymes as well as elements levels were determined. Serum and liver tissues were subjected to NMR-based metabolomics and multivariate statistical analysis. Results HCW could significantly reduce the elevated levels of fibrosis markers such as hyaluronidase, laminin, Type III procollagen and Type IV collagen in the serum, improve the activities of the antioxidant enzymes, and effectively reverse the abnormal levels of elements in liver fibrosis rats. Correlation network analysis revealed that HCW could treat liver fibrosis by ameliorating oxidative stress, repairing the impaired energy metabolisms and reversing the disturbed amino acids and nucleic acids metabolisms. Conclusion This integrated metabolomics approach confirmed the validity of the traditional use of HCW in the treatment of liber fibrosis, providing new insights into the underlying mechanisms.

Tibetan medicine Herpetospermum caudigerum Wall. (HCW) has long been employed to treat hepatitis, inflammatory diseases and jaundice according to the records of "The Four Medical Tantras" in China. This study was investigated to explore the protective effects of HCW on hepatic fibrosis and the possible mechanism in a rat model. Hepatic fibrosis was established by intragastric administration of 3 ml/kg carbon tetrachloride (CCl4 ) twice a week for 6 weeks. CCl4 -treated rats were received HCW (1 and 3 g/kg/d) and silymarin (0.1 g/kg/d) from 3 to 6 weeks. The results showed that HCW could significantly decrease the levels of AST, ALT, HA, LN, PCIII, Col IV, TNF-α, IL-1β and IL-6. Moreover, HCW could effectively inhibit collagen deposition and reduce the pathological damage. Analysis experiments finally exhibited that HCW was able to markedly inhibit hepatic fibrosis by modulating the expressions of NF-κB p65, IκBα, Samd3 and TGF-β1 proteins. Therefore, our results suggest that HCW has hepatoprotective activity against CCl4 -induced hepatic fibrosis in rats by regulating the inflammatory responses.
PurposeThe Society for Integrative Oncology (SIO) produced an evidence-based guideline on use of integrative therapies during and after breast cancer treatment that was determined to be relevant to the American Society of Clinical Oncology (ASCO) membership. ASCO considered the guideline for endorsement.MethodsThe SIO guideline addressed the use of integrative therapies for the management of symptoms and adverse effects, such as anxiety and stress, mood disorders, fatigue, quality of life, chemotherapy-induced nausea and vomiting, lymphedema, chemotherapy-induced peripheral neuropathy, pain, and sleep disturbance. Interventions of interest included mind and body practices, natural products, and lifestyle modifications. SIO systematic reviews focused on randomized controlled trials that were published from 1990 through 2015. The SIO guideline was reviewed by ASCO content experts for clinical accuracy and by ASCO methodologists for developmental rigor. On favorable review, an ASCO Expert Panel was convened to review the guideline contents and recommendations.ResultsThe ASCO Expert Panel determined that the recommendations in the SIO guidelinepublished in 2017are clear, thorough, and based on the most relevant scientific evidence. ASCO endorsed the guideline with a few added discussion points.RecommendationsKey recommendations include the following: Music therapy, meditation, stress management, and yoga are recommended for anxiety/stress reduction. Meditation, relaxation, yoga, massage, and music therapy are recommended for depression/mood disorders. Meditation and yoga are recommended to improve quality of life. Acupressure and acupuncture are recommended for reducing chemotherapy-induced nausea and vomiting. Acetyl-l-carnitine is not recommended to prevent chemotherapy-induced peripheral neuropathy because of a possibility of harm. No strong evidence supports the use of ingested dietary supplements to manage breast cancer treatment-related adverse effects.

Mindfulness training is increasingly being integrated as a contemplative pedagogy in social work education. Social work educators are using mindfulness training to support student self-care, facilitate critical reflection and enhance dialogue around challenging topics, integrate spiritual and holistic perspectives, and to help students develop direct practice skills. In this article, we describe a course we developed, where we use mindfulness training as a means of enhancing student self-care and well-being. We draw on our own experience, student evaluations, and the existing literature to identify and reflect upon key considerations in introducing this innovative experiential pedagogy into the social work classroom.
Chemotherapy-induced peripheral neuropathy (CIPN) is a serious dose-limiting side-effect without any FDA-approved treatment option. Prior reviews focus mostly on pharmacological interventions, but nonpharmaceutical interventions have also been evaluated. A Web of Science and PubMed database search to identify relevant RCTs from January 2005 to May 2015 included the terms: CIPN, cancer; and supplements, vitamin E, goshajinkigan, kampo, acetyl-L-carnitine, carnitine, alpha-lipoic acid, omega-3, glutamine, or glutamate; or massage, acupuncture, mind-body practice, yoga, meditation, Tai-Chi, physical activity, or exercise. Of 1465 publications screened, 12 RCTs evaluated natural products and one evaluated electroacupuncture. Vitamin E may help prevent CIPN. L-Glutamine, goshajinkigan, and omega-3 are also promising. Acetyl-L-carnitine may worsen CIPN and alpha-lipoic acid activity is unknown. Electroacupuncture was not superior to placebo. No RCTs were published regarding other complementary therapies, although some studies mention positive incidental findings. Natural products and complementary therapies deserve further investigation, given the lack of effective CIPN interventions.
Small-molecule fluorescence imaging in the second near-infrared (NIR-II, 1000-1700 nm) window has gained increasing interest in clinical application. Till now, very few studies have been exploited in the small-molecule fluorophores with both excitation and emission in the NIR-II window. Inspired by the indocyanine green structure, a series of polymethine dyes with both absorption and emission in the NIR-II window have been developed for NIR-II imaging, providing the feasibility to directly compare optical imaging in the NIR-IIa (1300-1400 nm) subwindow under 1064 nm excitation with that in the NIR-II window under 808 nm excitation. The signal-background ratio and the tumor-normal tissue ratio achieved great improvement under 1064 nm excitation in the imaging of mouse blood pool and U87 glioma tumors. Our study not only introduces a broadband emission fluorophore for both NIR-II and NIR-IIa imaging, but also reveals the advantages of NIR-II excitation over NIR-I in in vivo imaging.
