Objective:To investigate the traditional Chinese medicine(TCM) and its pathology relationship in IgA nephropathy(IgAN),so as to deduce the pathogenetic condition and prognosis,and guide the clinic therapy.Methods: 53 cases of IgAN were analyzed retrospectively,syndrome differentiations were concluded by the diagnosis criteria of TCM syndrome in the clinic research and guiding principe of the curment new herd in chronic nephritis in 2002 into deficiency of spleen and kidney qi,deficiency of liver and kidney yin,deficiency of both qi and yin,and the accompanied syndrome as affection of exogenous wind-heat,endoretention of damp-heat and blood stagnation.The relationship among pathological parameters,pathological stages and the above syndromes were observed.Results:Compared the three clinical syndromes of deficiency of spleen and kidney qi,deficiency of liver and kidney yin and deficiency of both qi and yin of 53 cases of patients,pathology change and pathological stage were the lightest in deficiency of spleen and kidney qi,on the contrary,the heaviest in deficiency of both qi and yin,P

AIM: To investigate the inhibitory effect of L-carnitine on high glucose-induced apoptosis of human aortic endothelial cells (HAECs) and the molecular mechanisms.METHODS: The apoptosis of HAECs was induced by high-glucose incubation.HAECs were treated with L-carnitine at different concentrations (50, 100 and 200 μmol/L).The cell viability was measured by MTT assay.The cell apoptosis was assessed by Hoechst 33258 staining and flow cytometry.Colorimetric method was employed to detect the caspase-3 activity in the HAECs.The protein expression and phosphorylation levels were determined by Western blot.RESULTS: High-glucose incubation dramatically decreased the cell viability and induced apoptosis.The protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme-1 (IRE1) and activating transcription factor 6 (ATF6) signaling pathways of endoplasmic reticulum stress were activated to induce cell apoptosis via down-stream caspase-4/3 cascade.However, L-carnitine treatment significantly attenuated the cell apoptosis and increased the cell viability in a concentration-dependent manner.L-carnitine also significantly suppressed endoplasmic reticulum stress and ATF6 signaling in high glucose-incubated HAECs without attenuating PERK and IRE1 signaling.The expression of site-1 protease (S1P) and site-2 protease (S2P) was inhibited by L-carnitine treatment, thus decreasing pro-apoptotic factor ATF6 p50 produced by ATF6 cleavage.CONCLUSION: L-carnitine inhibits high glucose-induced apoptosis of HAECs by inhibiting ATF6 signaling.

Objective To summarize the interventional management for early hepatic arterial thrombosis(HAT)after liver transplantation.Methods 32 patients suspected of HAT or HAS after liver transplantation in 502 cases from April 2001 to September 2006 were done hepatic arterial angiography.Among them,20 patients were confirmed as HAT immediately through hepatic arterial angiography,and were further treated by transarterial thrombolysis,pereutaneous transluminal angioplasty(PTA)and stent-graft placement. Results HAT was identified in 20 patients(3.98%),occurring in the median 4.5 days(2～19 days)after liver transplantation.The sites of all the thrombosis were found at the anastomotic point of the hepatic artery.5 cases were treated by PTA and 3 cases by stent placement during the transarterial thrombolysis.Coil and stent-graft were used in 2 cases with hepatic arterial anastomostic hemorrhage.Hepatic arterial recanalization was obtained in 20 cases.The period of thrombolysis was 2.5 clays(2-11 days).Conclusions Continuous infusion of urokinase through hepatic artery with catheter,PTA and stent placement are effective modalities for hepatic arterial thrombosis after liver transplantation.(J Intervent Radiol,2007,16:799-802)

The pre-metabolic disease state is the body state of substance metabolism disorder that has not yet reached the physical and chemical indicators of the disease, and abnormal glucose metabolism is often the key link of metabolic disorder. In TCM, the healthy function of the spleen is the cornerstone of the production and distribution of fine substances. This article discussed the pre-metabolic disease state based on the theory of "overflow of Five Qi" in the Nei Jing, taking the loss of spleen preparedness as the starting point, in order to provide new ideas and directions for the prevention and treatment of clinical metabolic diseases.
