Siwei Jianghuang Decoction Powder (SWJH) documented originally in the Four Medical Tantras-Blue Glaze exhibited beneficial effects on diabetic nephropathy (DN) via combined synergistically action of multiple formula components including Curcumae longae Rhizoma, Berberidis dictyophyllae Cortex, Phyllanthi Fructus and Tribuli Fructus. This study investigated the effects of SWJH on DN in db/db mice and possible underlying mechanisms. The ten weeks old db/db mice treated with SWJH by intra-gastric administration once a day for 8 weeks. After 8 weeks, body weight, water and food intake of mice were recorded. The level of fasting blood glucose (FBG) was measured. Serum creatinine (Scr), blood urea nitrogen (BUN), urine microalbumin (UMAlb), serum uric acid (UA) and urinary albumin excretion (UAE) were detected. An enzyme-linked immunosorbent assay was performed to test serum vascular endothelial growth factor (VEGF) and transforming growth factor-β1 (TGF-β1). Real-time PCR and Western blot analysis were used to test mRNA and protein expression of hypoxia inducible factor-1α (HIF-1α), VEGF and TGF-β1 in kidney tissue. SWJH treatment significantly reduced the levels of FBG, Scr, BUN, UMAlb, UA and UAE and retarded renal fibrosis. SWJH treatment further significantly reduced serum TGF-β1 level and downregulated the expression of HIF-1α, VEGF and TGF-β1 at both mRNA and protein levels. Principal component analysis and partial least squares regression and hierarchical cluster analysis demonstrated that SWJH treatment significantly ameliorated renal damage in DN mice. These consequences suggested that SWJH formulations were effective in the treatment of DN through regulating the HIF-1α, VEGF and TGF-β1 overexpression.
To explore the medication regularity of Tibetan medicine in the treatment of spleen and stomach diseases, analyze the potential drug targets and interactions of the prescriptions, and reveal the mechanism of Tibetan medicine in the treatment of spleen and stomach diseases. The prescriptions in Tibetan medicine for treatment of spleen and stomach diseases were collected, and Traditional Chinese Medicine Inheritance Support System (TCMISS) was used to analyze the association rules between the herbs and discover the core herbs and new prescriptions. The integrated pharmacology platform V1.0 software was used to construct "herb-compound-target" network and investigate the interactions between various herbs and related pathways of Tibetan medicine Wuwei Shiliu powder in the treatment of spleen and stomach diseases. Among the 216 prescriptions of Tibetan medicine in the treatment of spleen and stomach diseases, pomegranate seed was used at a highest frequency (118 times), followed by white cardamom (107 times) and comatose (107 times). 12 new prescriptions were evolved by using the association rules (support>=34%, confidence>=0.85). 5 242 related drug targets and 20 related pathways were obtained from classic formula Wuwei Shiliu Powder (FDR<0.01). It was proposed that Tibetan medicine treatment for spleen and stomach diseases was mainly based on proliferation of "stomach fire" and the main drugs were for regulating Qi-flowing for strengthening spleen. The mechanism may be associated with regulation of digestive juice secretion, proton pump, mitochondria, regulation of intestinal digestion and immunity, the body's immunity to microorganisms function and other multiple targets and pathways to achieve the joint intervention.
The seeds of Herpetospermum pedunculosun (Ser.) C.B.Clarke. (HPD), Mormodica cochinchinensis (Lour.) Spreng. (MCC) and Mormodica charantia L. (MCR) share the same common name ("Bolengguazi") in the Tibetan medicine. The anti-inflammatory activities of the three "Bolengguazi" were evaluated using egg album-induced paw edema and cotton-pellet granuloma tests. Among them, HPD is the most active one in both models. Results showed that oral administration of ethanol extract of HPD seed (200 and 400mg/kg) significantly suppressed the development of egg albumin-induced paw edema (P<0.01). In the chronic test, the ethanol extract of HPD seed (200 and 400mg/kg) showed significant reduction in granuloma weight of rats (P<0.05). The anti-inflammatory effect of the ethanol HPD seed was similar to that of indomethacin (10mg/kg). Moreover, the free radical scavenging activities of "Bolengguazi" were investigated using the DPPH test. Only the ethanol extract of HPD seed showed a moderate free radical scavenging effect on DPPH (IC50, 198.69 microg/ml) when compared with the positive control, V(E), (IC50, 44.91 microg/ml). The HPD seeds showed more significant anti-inflammatory activities in additional to higher free radical scavenging activities than that of the MCC and MCR seeds. The results of the present study provide a scientific basis to explain, in part, the popular use of HPD seed in Tibetan folk medicine as "Bolengguazi". The present study also supports the claims by the traditional Tibetan medicine practitioners about the use of HPD seeds in inflammatory diseases, such as "Chiba".

Tibetan medicinal plants have been used for more than 2 000 years. In order to find their differences in antioxidant activity, total phenolics and total flavonoids between "hot-nature" and "cold-nature" herbs, we investigated the antioxidant activities of 40 Tibetan herbs from Qinghai plateau, with 20 herbs in cold-nature and 20 herbs in hot-nature. Antioxidant capacities were evaluated by the following methods: scavenging ABTS•(+) (2, 2'azinobis-(3-ethylbenz-thiazoline-6-sulfonic acid), scavenging O2•(-), and Ferric-reducing antioxidant power (FRAP). The effects on inhibition of mitochondrion lipid peroxidation were determined by measuring the formation of TBARS (Thiobarbituric acid reactive substrates). Total phenolics and flavonoids were estimated by Folin-Ciocalteu and NaNO2-Al(NO3)3-NaOH colorimetric methods. Interestingly, the cold-nature herbs displayed higher antioxidant activities than the hot-nature ones, corresponding to nearly three-fold higher total phenolic contents in the cold-nature herbs. Moreover, the antioxidant activities correlated linearly with the levels of total phenolics for both cold-nature and hot-nature herbs, but only with the levels of total flavonoids for the hot-nature herbs. The results suggested that the phenolic compounds, but not the flavonoids, play the major role in antioxidant capacities of the cold-nature herbs. These findings could shed new lights on the study the theory of Tibetan medicine.

Background: Veronica ciliata Fisch., widely distributed in western China, has been traditionally used in Tibetan Medicine as a treatment for hepatitis, cholecystitis, rheumatism, and urticaria. However, V. ciliata Fisch. has not been subjected to detailed chemical constitution analysis and the bioactive studies were restricted to its crude extracts. It is necessary to investigate the active chemical components of these extracts and identify their biological effects. Results: Four iridoid glycosides, (veronicoside, cataposide, amphicoside, and verminoside) were isolated from the ethyl acetate fraction. Among these compounds, veronicoside and verminoside were isolated for the first time from this plant. These compounds exhibited strong antioxidant activity and inhibitory activity on HepG2 cell proliferation. The antioxidant activity of verminoside was equal to Vc. Cataposide, amphicoside and verminoside had stronger anti-hepatocarcinoma activity than 5-fluorouracil. Conclusions: Four iridoid glycosides,(veronicoside, cataposide, amphicoside and verminoside) were isolated from the extract of V. ciliata Fisch. using bioassay-guided screening.Among these compounds, veronicoside and verminoside were isolated for the first time from this plant. The above results indicated that these compounds were the active chemical components responsible for the antioxidant and anti-hepatocarcinoma properties of V. ciliata Fisch. The underlying mechanism of their bioactivity is worthy of further investigation. [Figure not available: see fulltext.

Biocompatible and bioresponsive microneedles (MNs) are emerging technology platforms for sustained drug release with a potential to be a key player in transdermal delivery of therapeutics. In this paper, an innovative biodegradable MNs patch for the sustained delivery of drugs using a polymer patch, which can adjust delivery rates based on its crosslinking degree, is reported. Gelatin methacryloyl (GelMA) is used as the base for engineering biodegradable MNs. The anticancer drug doxorubicin (DOX) is loaded into GelMA MNs using the one molding step. The GelMA MNs can efficiently penetrate the <i>stratum corneum</i> layer of a mouse cadaver skin. Mechanical properties and drug release behavior of the GelMA MNs can be adjusted by tuning the degree of crosslinking. The efficacy of the DOX released from the GelMA MNs is tested and the anticancer efficacy of the released drugs against melanoma cell line A375 is demonstrated. Since GelMA is a versatile material in engineering tissue scaffolds, it is expected that the GelMA MNs can be used as a platform for the delivery of various therapeutics.<br><b>A biocompatible and biodegradable microneedles patch</b> based on gelatin methacryloyl are developed for transcutaneous delivery of drugs. The microneedles can efficiently penetrate the <i>stratum corneum</i> layer in a mouse cadaver skin model and the drug release profile can be controlled by tuning the crosslinking degrees. The model drug doxorubicin keeps its anticancer efficacy after enzyme-mediated release from the patch.
Seven phenolic compounds, <b>1</b> - <b>7</b>, including a new organic acid gallate, mucic acid 1-ethyl 6-methyl ester 2-<i>O</i>-gallate (<b>7</b>), were isolated from the MeOH extract of the fruits of <i>Phyllanthus emblica</i> L.

Soil respiration (Rs) is an important source of atmospheric CO2 flux and is sensitive to changes in soil nutrient and water contents. Despite extensive studies on the effects of enhanced atmospheric nitrogen (N) deposition and changes in precipitation (P) on Rs, few studies have taken into account the effects of interactions between these factors on Rs of alpine grasslands. To address these questions, we investigated the effects of N addition (10 g N m-2 yr-1), changes in precipitation (±50% precipitation), and their interaction on soil respiration and its components, including heterotrophic respiration (Rh) and autotrophic respiration (Ra),in a Tibetan alpine steppe during three consecutive growing seasons. We found that Rs differed in its response to N addition and precipitation regimes. Specifically, decreased precipitation led to a significant reduction in Rs during the last two years, whereas N addition minimally impacted Rs. Another important finding was that soil respiration components differed in their response to N addition and precipitation regimes. Nitrogen addition significantly enhanced Ra, whereas Rh was not altered in response to N addition. By contrast, the precipitation regime led to marked changes in Rh, but exhibited marginally significant effects on Ra. Therefore, our findings highlighted that soil respiration differed in its response to N addition and precipitation regimes mainly due to the different responses of soil respiration components to these factors. Therefore, carbon dynamics should take soil respiration components into account under global change scenarios.
Tibetan culture and livelihoods depend on native plants for medicine, food, grazing, wood, as well as cash from market sales. The Medicine Mountains (part of the Hengduan Mountains) of the eastern Himalayas, with tremendous plant diversity derived from steep gradients of both elevation and precipitation, have traditionally been an important source of Tibetan medicinal plants. We examine climate change in this area and vegetation patterns influenced by biogeography, precipitation and elevation (NMS and CCA ordinations of GLORIA plots). The Alpine environment has the highest plant diversity and most useful plants and is the most susceptible to climate change with impacts on traditional Tibetan culture and livelihoods—particularly Tibetan medicine and herding.
BackgroundMeditation has been increasingly evaluated as an important complementary therapeutic tool for the treatment of depression. The present study employed resting-state functional magnetic resonance imaging (rs-fMRI) to examine the effect of body–mind relaxation meditation induction (BMRMI) on the brain activity of depressed patients and to investigate possible mechanisms of action for this complex intervention.
Method
21 major depressive disorder patients (MDDs) and 24 age and gender-matched healthy controls (HCs) received rs-fMRI scans at baseline and after listening to a selection of audio designed to induce body–mind relaxation meditation. The rs-fMRI data were analyzed using Matlab toolbox to obtain the amplitude of low-frequency fluctuations (ALFF) of the BOLD signal for the whole brain. A mixed-design repeated measures analysis of variance (ANOVA) was performed on the whole brain to find which brain regions were affected by the BMRMI. An additional functional connectivity analysis was used to identify any atypical connection patterns after the BMRMI.
Results
After the BMRMI experience, both the MDDs and HCs showed decreased ALFF values in the bilateral frontal pole (BA10). Additionally, increased functional connectivity from the right dorsal medial prefrontal cortex (dmPFC) to the left dorsal lateral prefrontal cortex (dlPFC) and the left lateral orbitofrontal cortex (OFC) was identified only in the MDDs after the BMRMI.
Limitation
In order to exclude the impact of other events on the participants׳ brain activity, the Hamilton Rating Scales for Depression (HDRS) was not measured after the body–mind relaxation induction.
Conclusion
Our findings support the hypothesis that body–mind relaxation meditation induction may regulate the activities of the prefrontal cortex and thus may have the potential to help patients construct reappraisal strategies that can modulate the brain activity in multiple emotion-processing systems.

This study is aimed to explore the effect of nitrogen, phosphorus and potassium combined application on the active components of Rhodiola crenulata. R. crenulata was used as the research object, "3414" fertilization experiment were conducted with regular fertilization of NPK(N 60 kg·hm⁻², P₂O₅ 100 kg·hm⁻²,KCl 160 kg·hm⁻²) to study the effect of different rates of NPK fertilization on the total amount of 4 phenolic constituents of gallic acid, salidroside, tyrol and ethyl gallate through field test. The results show that the content of salidroside was higher in the treatment of N₁P₂K₁ and N₁P₂K₂, andthe total amount of four phenols was higher in the treatment of N₁P₂K₂ and N₂P₂K₂. The suitable level of nitrogen, phosphorus and potassium promoted the accumulation of the 4 kinds of phenols.The amount of fertilizer recommended by the three factor fertilizer effect equation,(N 0 kg·hm⁻²,P₂O₅ 150 kg·hm⁻²,KCl 31.71 kg·hm⁻²) obtained the highest content of salidroside, and it was 1.54%.（N 35.54 kg·hm⁻²,P₂O₅ 150 kg·hm⁻²,KCl 237.73 kg·hm⁻²）obtained the highest content of 4 kinds of phenolic compounds, and it was 1.93%. This study provides a reference for the standardization of artificial planting of endangered Tibetan medicine.
A typical indicator of sepsis is the development of progressive subcutaneous and body‑cavity edema, which is caused by the breakdown of endothelial barrier function, leading to a marked increase in vascular permeability. Microvascular leakage predisposes to microvascular thrombosis, breakdown of microcirculatory flow and organ failure, which are common events preceding mortality in patients with severe sepsis. Melilotus suaveolens (M. suaveolens) is a Traditional Tibetan Medicine. Previous pharmacological studies have demonstrated that an ethanolic extract of M. suaveolens has powerful anti‑inflammatory activity and leads to an improvement in capillary permeability. However, the mechanisms underlying its pharmacological activity remain elusive. The present study aimed to assess the impact of M. suaveolens extract tablets on pulmonary vascular permeability, and their effect on regulating lung inflammation and the expression of vascular endothelial growth factor (VEGF) in the lung tissue of rats with sepsis. A cecal ligation and puncture (CLP) sepsis model was established for both the control and treatment groups. ~2 h prior to surgery, 25 mg/kg of M. suaveolens extract tablet was administered to the treatment group. Polymerase chain reaction and western blot analyses were used to assess the expression of nuclear factor (NF)‑κB and VEGF in the lung tissue, and ELISA was applied to detect changes in serum tumor necrosis factor‑α as well as interleukins (IL) ‑1, ‑4, ‑6, and ‑10. The lung permeability, wet/dry weight ratio and lung pathology were determined. The results demonstrated that in the lung tissue of CLP‑rats with sepsis, M. suaveolens extract inhibited the expression of NF‑κB, reduced the inflammatory response and blocked the expression of VEGF, and thus significantly decreased lung microvascular permeability. The effects of M. Suaveolens extract may be of potential use in the treatment of CLP‑mediated lung microvascular permeability.
Objective: This study aimed to investigate effects of mindfulness-based stress reduction (MBSR) on anxiety, depression and quality of life in patients with intrauterine adhesion. Methods: Patients who received therapy for intrauterine adhesion (IUA) were recruited and randomized into MBSR group and Wait-List group (WL group). 71 women who received routine physical examination were recruited as healthy controls. Patients in MBSR group received MBSR training for 8 weeks. Results: There were 76 patients in MBSR group, 75 patients in WL group and 71 subjects in control group. When compared with control group, the scores of anxiety and depression increased significantly and the score of quality of life reduced significantly before intervention. In patients, the scores of quality of life in all the domains were negatively related to the scores of anxiety and depression (P<0.05). After MBSR for 8 weeks, there was a significant time and group interaction for the anxiety score (F=55.168, P<0.001) and depression score (F=252.485, P<0.001). The MBSR group showed a decrease in the anxiety and depression score, while the WL group did not. The quality of life (except for bodily pain) in the MBSR group was also significantly improved. The recurrence rate in the MBSR group was 18.4%, which was significantly lower than that in WL group (34.7%; P=0.024). Conclusion: IUA patients have evident anxiety and depression, which significantly reduces the life quality of patients. MBSR may improve the anxiety and depression of IUA patients during therapy, promote the post-operative recovery and improve their quality of life.

PURPOSE: Breast cancer is the most common female cancer. The aim of this study was to assess the impact of yoga on lymphedema in breast cancer survivors.DESIGN: Repeated measures before and after the intervention. We enrolled 15 women with breast cancer who had not previously worn elastic clothing to treat lymphedema.
METHODS: The program was led by a certified trainer and consisted of 60-minute sessions, three times a week for 12 weeks. The volumes of the affected and normal limbs were measured. A self-assessed edema score was also recorded.
FINDINGS: Fifteen patients completed the program, none of whom suffered from complications related to exercise. There was no significant edema after exercise. No significant differences were noted in subgroup analysis by age or the affected arm.
CONCLUSIONS: Yoga does not induce lymphedema.
CLINICAL RELEVANCE: Lymphedema is usually treated with uncomfortable elastic clothing, and high-resistance exercise may induce edema. Yoga may be suitable for these patients.
To study the effect of Tibetan medicine Zuotai on the activity, protein and mRNA expression of CYP1A2 and NAT2, three different doses (1.2, 3.8 and 12 mg x kg(-1)) of Zuotai were administrated orally to rats once a day or once daily for twelve days, separately. Rats were administrated orally caffeine (CF) on the second day after Zuotai administration, and the urine concentration of CF metabolite 5-acetylamino-6-formylamino-3-methyl-uracil (AFMU), 1-methyluric acid (1U), 1-methylxanthine (1X), 1, 7-dimethylxanthine (17U) at 5 h after study drug administration was determined by RP-HPLC. The activity of CYP1A2 and NAT2 was evaluated by the ratio of metabolites (AFMU+1X+1U)/17U and the ratio of AFMU/(AFMU+1X+1U), respectively. The protein and mRNA expression of CYP1A2 and NAT2 were determined by ELISA and RT-PCR method, respectively. After single administration of Zuotai 3.8 mg x kg(-1) and repeated administration of Zuotai 3.8 and 12 mg x kg(-1), the activity of CYP1A2 and NAT2 decreased significantly compared with control group and there was no significant difference between other dose group and control group. The protein expression of CYP1A2 was significant lower than that in control group after repeated administration of Zuotai 12 mg x kg(-1), and the mRNA expression of CYP1A2 decreased significantly compared with that of control group after single administration of Zuotai 3.8 mg x kg(-1) and repeated admistration of Zuotai 12 mg x kg(-1), separately. The protein expression of NAT2 decreased significantly compared with that of control group after single and repeated administration of Zuotai 3.8 mg x kg(-1), respectively, and the mRNA expression of CYP1A2 decreased significantly compared with control group after single administration of Zuotai 3.8 mg x kg(-1). This study found that Tibetan medicine Zuotai had significant effect on the activity, protein and mRNA expression of CYP1A2 and NAT2.
This article reviews the current state of empirical research on the purported "new wave" of cognitive behavioral therapy (CBT). A particular emphasis is given to mindfulness-based treatments and acceptance and commitment therapy (ACT). Mindfulness-based approaches and ACT are evaluated with regard to their efficacy and comparison with traditional CBT. Deviations from CBT are explained within the context of theory, specifically in terms of the role of cognitions. These differences, however, are not irreconcilable in requiring a separate classification of "new wave" treatments. While subtle and important differences on the theoretical and procedural level might exist, available data do not favor one treatment over another, and do not suggest differential mechanisms of action that warrant a dramatic separation from the CBT family of approaches. Instead, the "new wave" treatments are consistent with the CBT approach, which refers to a family of interventions rather than a single treatment. Thus, the term "new wave" is potentially misleading because it is not an accurate reflection of the contemporary literature.
