Objective To examine the possible role of hepatocyte growth factor (HGF) in transdifferentiation induced by TGF ? 1 in cultured human renal tubular epithelial cell lines(HKC). Methods The HKC cells were divided into negative control, positive control, HGF group, HGF inhibition group, HGF delayed administration group. Then the expression of E cadherin and alpha smooth muscle actin(? SMA)of HKC cells were assessed by indirect immunofluorescence ,the expression of ? SMA mRNA of HKC cells were assessed by reverse transcriptase ploymerase chain reaction(RT PCR). Results HKC cells treated with TGF ? 1 present a clear fibroblast like morphology, loss of epithelial marker E cadehrin and de novo expression of ? SMA. Simultaneous incubation of HGF or delayed administration of HGF abrogated the ? SMA expression and E cadherin depression triggered by TGF ? 1 in HKC cells in a dose dependent manner. HGF also blocked morphologic transformation of tubular epithelial cells. Conclusion TGF ? 1 is a key mediator that regulates the transdifferentiation of tubular epithelial cells into ? SMA (+) myofibroblast, HGF can inhibit transdifferentiation of HKC cells induced by TGF ? 1 , Delayed administration of HGF effectively suppresses, and partially reverses myofibroblastic transition of tubular epithelial cells

With high-performance liquid chromatography ( HPLC ) we have determined the content of Vit C in adrenal glands of mice at different adrenocortical function. The results indicated that the content of Vit C in mice adrenal glands was increased when the adrenocortical function was enhanced with ACTH and Vit C content was decreased when dexamethason was administered. The resultes also indicated that by HPLC-E C the VitC content in mice adrenal glands could be exactly determined.

Autophagy is an active research area in the biomedical field as its role has been identified in many physiological and pathological processes. Accordingly, there is a growing demand to identify, quantify and manipulate the process accurately. Meanwhile, there is great interest in identifying compounds that modulate autophagy because they may have applications in the treatment of a variety of autophagy-related diseases. In this review, we summarize the current status of autophagy screening systems to facilitate identification of autophagy modulators.

Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) are considered as the lower He-sea points, which are located along the leg lines of stomach meridian of foot Yangming from top to bottom. According to the corresponding zang-fu of lower He-sea points, the distribution order from top to bottom is stomach, large intestine and small intestine. This is significantly different from digestive physiology function sequence of stomach, small intestine and large intestine in modern medicine. However, it conforms to their anatomical position from top to bottom. In order to make a further confirmation that the indication specificity of Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) is closely associated with anatomical location, a great number of ancient and modern literature is reviewed. It is found that the functions of the three acupoints are obviously related to stomach, large intestine and small intestine, respectively, indicating that the sequence of Zusanli (ST 36), Shangjuxu (ST 37) and Xiajuxu (ST 39) is related to anatomical position of corresponding zang-fu. This study conclusion could play an important role for exploring the significance of anatomical location in indication specificity of acupoints.

To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.
