Abstract
OBJECTIVE To evaluate if berberine can act on vitamin D receptors (VDR) and thereby regulate the expression of tight junction proteins (TJPs) in irritable bowel syndrame-diarrhea-predominant (IBS-D) rats. METHODS The newborn rats were induced into IBS-D rat model via neonatal maternal separation combined with acetic acid chemical stimulation. After modeling, the model was evaluated and rats were divided into the control group and berberine treatment groups (0.85, 1.7 and 3.4 mg/kg, once a day for 2 weeks). The distal colon was obtained and colonic epithelial cells (CECs) were isolated and cultured after IBS-D model evaluation. The vitamin D receptor response element (VDRE) reporter gene was determined in the CECs of IBS-D rats to analyze the effect of berberine on the VDRE promoter. VDR overexpression or silencing technology was used to analyze whether VDR plays a role in promoting intestinal barrier repair, and to determine which region of VDR plays a role in berberine-regulated intestinal TJPs. RESULTS The IBS-D rat model was successfully constructed and the symptoms were improved by berberine in a dose-dependent manner (P<0.05). The activity of VDRE promoter was also effectively promoted by berberine (P<0.05). Berberine increased the expression of TJPs in IBS-D CECs (P<0.05). VDR expression was significantly increased after transfection of different domains of VDR when compared to normal control and basic plasmid groups (all P<0.05). RT-qPCR and Western blot results showed that compared with the blank group, expressions of occludin and zonula occludens-1 were significantly higher in VDR containing groups (all P<0.05). Berberine plus pCMV-Myc-VDR-N group exerted the highest expression levels of occludin and zonula occludens-1 (P<0.05). CONCLUSION Berberine enhances intestinal mucosal barrier function of IBS-D rats by promoting VDR activity, and the main site of action is the N-terminal region of VDR.

Abstract
Edible bird's nest (EBN) is a popular and expensive food material. The limited supply and great demand result in the use of adulterants. The authenticity concern is raised due to the lack of appropriate quality markers. Herein, this study aims to provide a specific oligosaccharide marker for rapid EBN authentication. Comparing the benzocaine (ABEE)-labeled saccharide profiles of multiple batches of EBN and adulterants indicates seven unique EBN oligosaccharides. The most abundant one, named BNM001, was selected as a marker and characterized to be Neu5Ac (2-3) Gal by MS and NMR spectra. This new oligosaccharide marker enables a rapid authentication of EBN within 10 min. ABEE labelling of this marker further upgraded the accuracy and sensitivity of the LC-qTOF-MS quantitative analysis. The relative marker content was associated with the quality of EBN products. These results suggest a specific and efficient quality marker for rapid authentication of EBN and related products.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is one kind of common functional bowel disease with obscure pathogenesis, and exploration about whole transcriptome profiling in IBS-D is still negligible. Conventional medications have limited effects, which makes focus shifted to traditional Chinese medicine (TCM). Tong-Xie-Yao-Fang, as a classic herbal formula in TCM, is pretty effective and safe for the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D), but the underlying therapeutic mechanism remains unknown. We aim to verify the efficacy and safety of TXYF granule (the formula particles mixed together) in IBS-D and elucidate the gene-level mechanism of IBS-D and therapeutic targets of TXYF granule based on whole transcriptome analysis. METHODS/DESIGN This is a randomized, double-blind, and placebo-controlled clinical trial consisting of 2 weeks of run-in period, 12 weeks of treatment period, and 8 weeks of follow-up period. We will enroll 120 participants with IBS-D, who will be randomly assigned to the TXYF granule group and the placebo group, and recruit additional 10 healthy individuals as controls for mechanistic outcome. The two groups respectively take TXYF granule or placebo orally for treatment. The primary outcome is the response rate of IBS-Symptom Severity Score (IBS-SSS). The secondary outcomes include adequate relief (AR), IBS-Quality of Life Questionnaire (IBS-QOL), and long-term efficacy. Mechanistic outcome is the whole transcriptome profiling of the intestinal mucosae from IBS participants before and after the treatment and healthy individuals. DISCUSSION This trial will prove the effectiveness and safety of TXYF granule with high-quality evidence and provide a penetrating and comprehensive perspective on the molecular mechanism of IBS-D by whole transcriptome analysis, which makes us pinpoint specific biomarkers of IBS-D and therapeutic targets of TXYF.

Abstract
In our previous reports, it was revealed that steroids in traditional Chinese medicine (TCM) have the therapeutic potential to treat bone disease. In the present study, an in vitro model of a vitamin D receptor response element (VDRE) reporter gene assay in mesenchymal stem cells (MSCs) was used to identify steroids that enhanced osteogenic differentiation of MSCs. (+)-cholesten-3-one (CN), which possesses a ketone group that is modified in cholesterol and cholesterol myristate, effectively promoted the activity of the VDRE promoter. Phenotypic cellular analysis indicated that CN induced differentiation of MSCs into osteogenic cells and increased expression of specific osteogenesis markers, including alkaline phosphatase, collagen II and Runt-related transcription factor 2. Furthermore, CN significantly increased the expression of osteopontin, the target of the vitamin D receptor (VDR), which indicated that CN may activate vitamin D receptor signaling. Over-expression of VDR or knockdown studies with VDR-small interfering RNA revealed that the pro-differentiation effects induced by CN required VDR. Furthermore, the present study determined that the C-terminal region of the VDR is responsible for the action of CN. Taken together, the present findings demonstrated that CN induced osteogenic differentiation of MSCs by activating VDR. The present study explored the regulation of stem cells by using a series of similar steroids and provided evidence to support a potential strategy for the screening of novel drugs to treat bone disease in the future.

Abstract
AIM: To assess the effect of Jisheng Shenqi decoction on homing of stem cells to the liver after transplantation of bone marrow mesenchymal stem cells (BMSCs) in cirrhotic rats.
METHODS: BMSCs were labeled with DAPI. Forty cirrhotic rats were randomly divided into four groups (15 cirrhotic rats in each group): A, B, C and D. Group A underwent BMSC transplantation, group B was given Jisheng Shenqi decoction combined with BMSC transplantation, group C received injection of granulocyte colony stimulating factor (G-CSF) combined with BMSC transplantation, and group D was treated with Jisheng Shenqi decoction. After 4 wk of treatment, liver tissues of rats in each group were taken to observe pathological changes, and cells labeled with DAPI were counted under a fluorescence microscope.
RESULTS: After treatment, two rats were dead in each of groups A and B. In group C, 4 rats were dead. Under the fluorescence microscope (×100), the counts of cells labeled with DAPI in the four groups were 7.31 ± 1.55, 20.85 ± 3.21, 15.82 ± 1.89, and 0.00 ± 0.00, respectively. The numbers of cells labeled with DAPI in groups B and C were significantly higher than that in group A (P < 0.01), and the number in group B was significantly higher than that in group C (P < 0.01).
CONCLUSION: Jisheng Shenqi decoction can effectively promote BMSC homing to the liver after BMSC transplantation, and is safe and feasible.

Abstract
We recently identified that cholesterol myristate in traditional Chinese medicine (TCM) is the active compound that increases proliferation of mesenchymal stem cell (MSCs). The present study is further to determine what signal pathway involves in effect of cholesterol myristate. Reverse transcription-PCR, Western blot and ELISA analysis show that cholesterol myristate increases the release of bone morphogenetic protein 4 (BMP4) from MSCs and the expression in the intracellular levels of BMP4 in a time- and dose dependent manner. However, structurally related steroids such as cholesterol and cholesten presented in TCM, both lack of the myristate, did not affect the secretion and expression of BMP4 on MSCs. These finds suggest that myristate is essential for the effects of cholesterol myristate. Furthermore, cholesterol myristate significantly increase BMPRIB levels of MSCs and the number of BMPRIB positive cells in a time- and dose dependent manner, but not BMPR IA or BMPR II. Our results indicate that action of cholesterol myristate may activate the BMP4-BMPRIB autocrine. Moreover, a blocking antibody against BMP4 or the BMP4 antagonist, noggin, partially reduced the effects of cholesterol myristate on MSCs proliferation. Thus, this study is to provide evidence that autocrine BMP4 signaling involves effect of cholesterol myristate on MSCs proliferation.
