Chinese Journal of General Surgery 1993;0(01):-
In order to explore the effect of hepatocholangiolithiasis on hepatobiiiary system, 160 patients with gallstone were observed by using choledochofiberscope, microscope and electnonic microscope. Damage of bile ducts was found in 84 cases(52.5%) and damage of the liver in 40 cases (25% ) with naked eyes. However, denaturation of hepatocytes occured in nearly all of the cases under microscope. To testify the clinical finding, animal experiments were made in 60 rabbits including infusion of gallstone or silt into bile ducts in groupl, 2, and subacute toxiologic experiment was made by direct injection of gallstone or silt into liver tissue(group3, 4). The results showed that under same condition damage of liver and bile duct caused by gallstone is more severe than that caused by silt. The authers suggest that hepatocholangiolithiasis can damage the hepatobiiiary system no matter whether there is obstruction or not. The harmful substance of gallstones can damage liver tissue directly. So effective therapy should be given as early as possible when the dis-gnosis of hepatocholangiolithiasis is made.

4.Comparison of wear resistance and hardness among different resin teeth
Chinese Journal of Tissue Engineering Research 2009;13(51):10109-10112
BACKGROUND: The wear resistance and hardness of artificial tooth would affect repairing effects in clinic. However, there is lack of professional standard for resin teeth in China.OBJECTIVE: To provide a theoretic foundation for the choosing of the resin teeth in clinic via comparing the wear resistance and hardness among 7 different resin teeth.DESIGN, TIME AND SETTING: A contrast observation. The experiment was performed at the laboratory of Mechanical Engineering College, Shanghai Jiao Tong University from November 2003 to May 2004.MATERIALS: A total of 7 kinds of different resin teeth were selected, namely, hard multi-layer synthetic resin teeth (A); multi-layer synthetic resin teeth (B); synthetic resin teeth (C); EMDURA resin teeth (D); three-layer synthetic resin teeth (E); optostar four-layer synthetic resin teeth (F); and Cosmo HXL (G).METHODS: The wear test was processed by a pin-plate wear machine. The result was measured by the weight loss through wearing and the surfaces of the wear scar were observed by a scanning electronic microscope (SEM); hardness was measured by Knoop hardness. Meanwhile, the relativity between the hardness and wear resistance of resin teeth was analyzed.MAIN OUTCOME MEASURES: The wear resistance and hardness of resin teeth.RESULTS: According to the weight loss and SEM examination, the wear resistance of the different resin teeth was D>A>G>E>B>F>C; and the hardness of different resin teeth was D>A>G>E>F>B>C. The correlation coefficient between the weight loss and hardness was -0.888 (P < 0.01).CONCLUSION: The variation of the wear resistance of the resin teeth may influenced by their different components, molecular weight and manufacturel methods. There are positive correlation between the hardness and wear resistance of resin teeth.

Objective To investigate the effect of fasting blood glucose control and its influencing factors in patients with type 2 diabetes mellitus (T2DM) in community.Methods 905 cases of patients with T2DM were collected in Rencheng District of Jining city according to the stratified cluster random sampling method.The general demographic characteristics and lifestyle of the subjects were collected by questionnaire survey,and the height,body weight,blood glucose,blood pressure and blood lipids were measured by physical examination.Multivariate Logistic regression analysis was used to analyze the influencing factors of blood glucose control.Results A total of 905 subjects were recruited in the analysis.74.70% of the subjects were aged 35 years above.The proportion reaching the control criteria of the blood glucose,blood pressure and cholesterol was 71.27% (645),29.83% (270) and 26.74%(242) of the subjects respectively.The influencing factors for blood glucose control in the subjects were age,duration of disease,blood pressure,weight,diet condition and psychological states and treatment compliance,and the differences were statistically significant(x2 =7.58,23.18,7.08,5.22,5.46,5.16,5.65,all P<0.05).Multivariate Logistic regression analysis showed that age and duration of disease were the risk factors of blood glucose control in patients with T2DM.Standard blood pressure control was the protective factor that affects the effect of blood glucose control (OR=1.430,95% CI=1.015-2.015,P<0.05).Conclusion The blood glucose control of T2DM patients need to be improved comprehensively in community.By strengthening the control of blood glucose and blood pressure,establishing good habits of life behavior and improving the ability of self management,patients with T2DM can improve their quality of life.
