[Objective] Analyze six differences between TCM and western medicine, which are raised by professor Chen Yi, in order to return the origin of TCM and cal on inheritance. [Methods] This article summarizes insightful views on the inheritance, development and innovation of TCM by professor Chen Yi from fol owing six differences between TCM and western medicine, as theory, thinking, culture, therapy, medication and disease cognition. [Re-sults] TCM, whose theory is based on principle, uses macro-control thinking, roots in Chinese culture, pays attention to syndrome differentiation, chooses one formula for one TCM type, masters herbs by drug properties theory and regards the healthy standard as harmony. While, western medicine, whose theory is based on reality, adopts the micro causal thinking, establishes on western culture, pays attention to disease diagnosing, uses one drug to treat one kind of disease, il ustrates western medicine by molecular formula and copes with causes or lesions of diseases. [Conclusion] Professor Chen Yi analyzes the six differences between TCM and western medicine and emphasizes TCM should be developed and innovated on the basis of inheritance, which is ful of enlightenment in methodology.

Objective To observe the role of mesenteric lymphatic pathway in severe acute pancreatitis (SAP)by detection of inflammatory factors levels and mesenteric lymph duct ligation in rats.Methods Twenty-four SD male rats were randomly divided into group A (SAP group),group B (SAP + mesenteric lymph duct ligation group)and group C(sham operation group),with eight rats in each group.Samples of portal vein blood and mesenter-ic lymph were collected for measuring the level of tumor necrosis factor α(TNF-α),interleukin 1β(IL-1β),interleu-kin 6(IL-6)and endotoxin at twelfth hour.The blood CDl b was tested at sixth hour.24h lactulose /mannitol excretion ratios(L/M)were taken as the intestinal mucosal permeability index by gavage of 100mg lactulose and 50mg mannitol solution.The terminal ileums were collected for pathological examination.Results The blood levels of endotoxin and cytokines(TNF-α,IL-1β,IL-6)were significantly increased in group A compared with group C(all P <0.01).Each factor′s concentration in lymph was much higher than that in portal vein blood,especially in group A.The endotoxin and cytokines(TNF-α,IL-1β,IL-6)levels in portal vein blood of group B were significantly decreased compared with group A(all P <0.05),but still higher than that of group C(all P <0.05).CDl b expression in group A was the highest,followed by group B,group C was the lowest (P <0.01).24h L/M in group A was significantly higher than that in group C (P <0.01),and L/Min group B decreased significantly compared with those in A group(P <0.05). Conclusion Lymphatic pathway is an important pathway of systemic inflammatory response induced by SAP,and ligation of mesenteric lymph duct has a protective effect on the organism.

BACKGROUND: The effect and mechanism of peroxisome proliferator-activated receptor gamma (PPARγ) agonists on transforming growth factor (TGF)-β1-induced fibrotic responses in lung fibroblasts remain unclear, and seldom reported.OBJECTIVE: To study the effects of PPARγ agonists on TGF-β1-induced fibrotic responses in lung fibroblasts, so as to investigate its effects in preventing pulmonary interstitial fibrosis of silicosis. METHODS: The pulmonary alveolar macrophage was prepared with 200 mg/L SiO2 and the supernatants were got. Chinese hamster lung fibroblasts were incubated with the prepared supernatants. Then a cellular model in vitro for studying pulmonary fibrosis induced by SiO2 was developed. Chinese hamster lung fibroblasts were cultured to observe the effects of the PPARγ ligand (15 d-PGJ2) and its agonists (troglitazone and ciglitazone) on the expression of TGF-β1-induced fibronectin. RT-PCR was used to detect the mRNA expression of fibronectin and Western blotting was used to detect the protein expression of fibronectin. RESULTS AND CONCLUSION: (1) The expression of TGF-β1 mRNA showed an effect in a dose- (0-5 μg/L) and time- (0-24 hours) dependent manner. (2) PPARγ ligands and agonists reduced the mRNA and protein expressions of fibronectin. Results suggested that PPARγ agonists can inhibit TGF-β1-induced fibronectin synthesis after stimulation by SiO2 and may play a potential role in preventing pulmonary interstitial fibrosis.
