Objective To study the anatomy of the hepatic arteries and imitate the way to deal with the hepatic arteries in the living liver transplantation of the left lateral lobe.Methods Thirty normal adult livers were anatomyzed and 30 casting models of livers were observed. The lengths, diameters and distributaries of the hepatic arteries were described Results The blood supply of the left lateral region came from proper hepatic artery, left hepatic artery and middle hepatic artery. The aberrant arteries included left inferior phrenic artery, left gastric artery and right gastric artery. They branched to supply the upper segment and the inferior segment Conclusion There are five types of hepatic arteries to supply the left liver lobe. The anatomy of hepatic arteries should be studied and a reasonable approach to gain a liver graft should be designed before transplantation. The hepatic arteries should be dealt with so as to anastomose with recipient hepatic arteries.

OBJECTIVE: To study the expression of Endophilin II and VEGF-C in human Laryngeal cancer and its relationship with the clinical treatment effect. METHOD: The expression and distribution of Endophilin II and VEGF-C protein were checked in 47 patients with laryngeal carcinoma in our hospital in 2006-09-2009-10 and 23 samples of normal tissues around the cancer by immunohistochemical staining SP method. After an appropriate surgical treatment, patients accepted a 5-year followup to evaluate their recurrence situation and 5-year survival rate. RESULT: Immunohistochemistry showed that Endophilin II protein was strongly positive expressed in normal tissues around the cancer (positive rate 82.61%). And the expression level was dependent on the lymph metastasis, T stage and lymph invasion (P < 0.05). Patients with positive Endophilin II expression had a higher survival rate and better recurrence situation. Expression of VEGF-C was significantly higher in laryngeal carcinoma than in normal tissue around the cancer (positive rate 51.06% and 13.04%). the expression level was dependent on the lymph metastasis and lymph invasion (P < 0.05), and negatively correlated with recurrence and 5-year survival rate. CONCLUSION Endophilin II and VEGF-C may involve in laryngeal cancer, and the expression of Endophilin II and VEGF-C has a positive correlation with pathological features and lymph metastasis, and both are related with recurrence and 5-year survival rate. So these two proteins are likely to be a potential target for diagnosis and treatment of laryngeal cancer.

ve To study the way of oxidative stress induced by soot rat pulmonary cells type Ⅱ ?Methods Before exposure to soot extracts, the rat pulmonary cells were pretreated with anti-oxidative agent, N-acetylcysteine (NAC), vitamin C, vitamin E and mannitol for 30 minutes, then the ceils were exposed to the soot extracts for 24 hours. MTT assay was applied to detect the cytotoxicity. Results It showed that NAC, vitamin C and vitamin E could reduce the cytotoxicity of rat pulmonary cell caused by soot, but no same change was observed in that of man-nitol. Conclusion It was suggested that the DNA oxidative stress of soot may be caused by multi-ways, such as in-duction of oxygen free radical and lipid peroxide etc.

Objective To analysis the basic condition of the health resources in Chongqing ,and to explore the effect of the al‐location of health resources on doctor‐patient relationship .Methods Health statistics yearbook of Chongqing city was collected ,the fairness of the allocation of health resources in chongqing carried on the analysis and evaluation ,using the DEA model to analyze and evaluation the efficiency of the allocation of health resources in chongqing ,self‐designed questionnaire was used;hospitals ,doc‐tors and patients were investigated ,the descriptive and statistical analysis carried on .Results The distribution of health resources in Chongqing was inequitable on a regional .This inequitable distribution had been evaluated to the effect that ,as per the DEA mod‐el ,7 prefectures were effective with another 5 slightly effective and 26 as DEA ineffective .In the 8 hospitals that had been investiga‐ted ,the occurrence of medical disputes was undergoing a surge ,which indicates the tense relation between doctors and patients .Con‐clusion The total amount of health resources in Chongqing is fairly insufficient ,the high quality health resources are scarce .Unbal‐anced allocation of health resources and allocation inefficiency is the main reason for nervous doctor‐patient relationship and contra‐diction focus .

Objective To explore any effect of calorie restriction on the proliferation of satellite cells in the skeletal muscles of elderly rats.Methods Twelve male C57BL rats aged 12 or 13 months were randomly divided in to an experimental group and a control group,each of 6.The control group was fed 75.09 kJ/d as normal,while the experimental group was provided with 45.05 kJ/d (60％ of normal).The intervention lasted for 15 weeks and each rat's weight was measured every week.After the intervention,limb muscle satellite cells were sorted by fluorescenceactivated cell sorting after digestion,and the cell cycle was analyzed.Western blotting was used to assess the expression of cyclin A,D1 and E.Results There was no significant difference in the average weight of the two groups before the experiment.After the 15 weeks the average weight of the experimental group had decreased significantly (to 19.5±0.4 g),and it was significantly lighter than that of the control group (31.9±0.5 g).The average percentage of the satellite cells in the G0/G1 phase had decreased significantly in the experimental group,but the percentage in the S phase had increased significantly.The expression of cyclin A and E was significantly greater in the experimental group compared with the control group,but the expression of cyclin D1 had decreased significantly.Conclusion Caloric restriction can delay the proliferation of satellite cells in the skeletal muscles of elderly mice.
