Modified Renshen Wumei decoction (MRWD), a famous traditional Chinese medicine, is widely used for treating persistent diarrhea. However, as the mechanism by which MRWD regulates diarrhea remains unknown, we examined the protective effects of MRWD on intestinal barrier integrity in a diarrhea model. In total, 48 male rats were randomly distributed to four treatment groups: the blank group (CK group), model group (MC group), Medilac-Vita group (MV group) and Chinese herb group (MRWD group). After a 21-day experiment, serum and colon samples were assessed. The diarrhea index, pathological examination findings and change in ᴅ-lactate and diamine oxidase (DAO) contents illustrated that the induction of diarrhea caused intestinal injury, which was ameliorated by MV and MRWD infusion. Metabolomics analysis identified several metabolites in the serum. Some critical metabolites, such as phosphoric acid, taurine, cortisone, leukotriene B4 and calcitriol, were found to be significantly elevated by MRWD infusion. Importantly, these differences correlated with mineral absorption and metabolism and peroxisome proliferator-activated receptor (PPAR) pathways. Moreover, it significantly increased the expression levels of TLR4, MyD88 and p-NF-κB p65 proteins and the contents of IL-1 and TNF-α, while the expression levels of occludin, claudin-1 and ZO-1 proteins decreased. These deleterious effects were significantly alleviated by MV and MRWD infusion. Our findings indicate that MRWD infusion helps alleviate diarrhea, possibly by maintaining electrolyte homeostasis, improving the intestinal barrier integrity, and inhibiting the TLR4/NF-κB axis.

Objectives: This study was conducted to review studies on somatization disorder in traditional Chinese medicine. Methods: We reviewed studies in the China National Knowledge Infrastructure (CNKI) to 2017. Keywords were 軀體化障碍, Somatization disorder, somatic symptom disorder. We included Randomized Controlled Trial (RCT), and excluded non-Randomized Controlled Trial (nRCT), non-related somatization disorder or traditional Chinese medicine, non-clinical trials, dissertations for degrees. Jadad scale and Cochrane Library's Risk of Bias (RoB) were used for assessment of the quality of studies. Results: Twelve studies were selected. The Chinese Classification of Mental Disorders-3 (CCMD-3) was most frequently used as diagnostic criteria for somatization disorder. As for outcome measurement, Hamilton Rating Scale for Depression (HAMD) was used most commonly. Meta-analysis of 10 studies revealed effective rate of Chinese Herbal Medicine groups (CHM) was significantly higher than Western Medicine groups (WM) (RR: 1.14, 95% CI: 1.02 to 1.27, p=0.02, $I^2=40%$). There was no significant difference in effective rate of CHM+WM and WM (RR: 1.12, 95% CI: 0.84 to 1.49, p=0.46, $I^2=83%$). And also, effective rate of Acupuncture group (Acu) revealed no significant difference compared to that of WM (RR: 1.17, 95% CI: 0.95 to 1.44, p=0.13, $I^2=84%$). For HAMD, there was significant difference in CHM vs, WM group and Acu vs. WM group. Quality of selected 12 RCTs was low. Conclusions: Therapies practiced in traditional Chinese medicine may be effective options for somatization disorder. treatment. For further clinical studies in Korean medicine, this study could be groundwork for development of diagnosis and treatment on somatization disorder.

Objectives: To establish a base for further research by reviewing studies on traditional Chinese medicine treatment for Tourette Syndrome. This is the purpose of this study. Methods: Clinical studies involving the effects of traditional Chinese medicine treatment for Tourette Syndrome, published January 2010~June 2017, were obtained from CNKI, Pubmed. Selected Studies were evaluated by the Jadad Scale. Results: Among a total of 252 articles, 39 articles that meet the criteria were selected. 'Diagnostic and Statistical Manual for Mental Disorders, 4th edition (DSM-IV)' was most frequently used as diagnosis criteria. 'Yale Global Tic Severity Scale (YGTSS)' was primarily used for outcome measurements. Most of the studies showed effective results of traditional Chinese medicine therapy. However, the quality of a selected clinical studies was low. Conclusions: Despite several limitations, various studies to prove limited yet effective traditional Chinese medicine treatment on Tourette Syndrome provides much significance. Subsequent studies conducted by the complementary systematic review and well-designed clinical trials using the methodological quality will be needed to more firmly validate the effect of traditional Chinese medicine therapy.

The pathological impact of haze upon the phyllosphere microbiota awaits investigation. A moderate degree of haze environment and a clean control were selected in Chengdu, China. Artemisia argyi, a ubiquitously distributed and extensively applied Chinese herb, was also chosen for experiment. Total genome DNA was extracted from leaf samples, and for metagenome sequencing, an Illumina HiSeq 2500 platform was applied. The results showed that the gene numbers of phyllosphere microbiota derived from haze leaves were lower than those of the clean control. The phyllosphere microbiota derived from both haze and clean groups shared the same top ten phyla; the abundances of Proteobacteria, Actinomycetes and Anorthococcuso of the haze group were substantially increased, while Ascomycetes and Basidiomycetes decreased. At the genus level, the abundances of Nocardia, Paracoccus, Marmoricola and Knoelia from haze leaves were markedly increased, while the yeasts were statistically decreased. KEGG retrieval demonstrated that the functional genes were most annotated to metabolism. An interesting find of this work is that the phyllosphere microbiota responsible for the synthesis of primary and secondary metabolites in A. argyi were significantly increased under a haze environment. Relatively enriched genes annotated by eggNOG belong to replication, recombination and repair, and genes classified into the glycoside hydrolase and glycosyltransferase enzymes were significantly increased. In summary, we found that both structure and function of phyllosphere microbiota are globally impacted by haze, while primary and secondary metabolites responsible for haze tolerance were considerably increased. These results suggest an adaptive strategy of plants for tolerating and confronting haze damage.

Although BMP9 is highly capable of promoting osteogenic differentiation of mesenchymal stem cell (MSCs), the molecular mechanism involved remains to be fully elucidated. Here, we explore the possible involvement and detail role of JNKs (c-Jun N-terminal kinases) in BMP9-induced osteogenic differentiation of MSCs. It was found that BMP9 stimulated the activation of JNKs in MSCs. BMP9-induced osteogenic differentiation of MSCs was dramatically inhibited by JNKs inhibitor SP600125. Moreover, BMP9-activated Smads signaling was decreased by SP600125 treatment in MSCs. The effects of inhibitor are reproduced with adenoviruses expressing siRNA targeted JNKs. Taken together, our results revealed that JNKs was activated in BMP9-induced osteogenic differentiation of MSCs. What is most noteworthy, however, is that inhibition of JNKs activity resulted in reduction of BMP9-induced osteogenic differentiation of MSCs, implying that activation of JNKs is essential for BMP9 osteoinductive activity.

Background: Radix et Rhizoma Ginseng (thereafter called ginseng) has been used as a medicinal herb for thousands of years to maintain people's physical vitality and is also a non-organ-specific cancer preventive and therapeutic traditional medicine in several epidemiologic and preclinical studies. Owing to few toxic side effects and strong enhancement on body immunity, ginseng has admirable application potential and value in cancer chemoprevention. The study aims at investigating the chemopreventive effects of ginseng on cutaneous carcinoma and the underlying mechanisms. Methods: The mouse skin cancer model was induced by 7,12-dimethylbenz[a]anthracene/12-O-tetradecanoylphorbol-13-acetate. Ultraperformance liquid chromatography/mass spectrometry was used for identifying various ginsenosides, the main active ingredients of ginseng. Comprehensive approaches (including network pharmacology, bioinformatics, and experimental verification) were used to explore the potential targets of ginseng. Results: Ginseng treatment inhibited cutaneous carcinoma in terms of initiation and promotion. The content of Rb1, Rb2, Rc, and Rd ginsenosides was the highest in both mouse blood and skin tissues. Ginseng and its active components well maintained the redox homeostasis and modulated the immune response in the model. Specifically, ginseng treatment inhibited the initiation of skin cancer by enhancing T-cell-mediated immune response through upregulating HSP27 expression and inhibited the promotion of skin cancer by maintaining cellular redox homeostasis through promoting nuclear translocation of Nrf2. Conclusion: According to the study results, ginseng can be potentially used for cutaneous carcinoma as a chemopreventive agent by enhancing cell-mediated immunity and maintaining redox homeostasis with multiple components, targets, and links.
