Journal of Clinical Surgery 2014;(9):669-672
Objective To explore the effects of anatomical and nonanatomical hepatectomy on the prognosis of patients with hepatocellular carcinoma(HCC).Methods A total of 62 HCC patients were enrolled,including 33 cases of anatomical hepatectomy(Group AH)and 29 cases of nonanatomical hepa-tectomy(Group IH).The operation situation and hematocrystallin(HB)loss were record.Fasting venous blood of HCC patients were extracted for detection of circulating AFP mRNA expression.The recurrence, mortality and complication rate were recorded at the same time.Results The operative time of Group AH was significantly higher than that of Group IH,while the bleeding volume and HB loss were lower(P<0.05).There were no significant differences in AFP mRNA expression and recurrence rate.The short-term mortality rate of Group AH was lower than Group IH(P<0.05 ),but their long-term mortality rates were similar(P>0.05 ).There was no significant difference in complication rate between groups.Patients of Group AH got more hepatosis due to liver cirrhosis or fibrosis,while patients of Group IH got more bleeding or infection due to the central tumor.Conclusion Anatomical hepatectomy has advantages in protecting artery and improving prognosis for HCC patients,but it has surgical risks for patients with serious patholog-ical damage in hepatic lobes,and nonanatomical hepatectomy may be considered.

3.Effects of hepatic stellate cells in hepatic diseases
Chinese Journal of Digestive Surgery 2014;13(1):73-76
Hepatic satellite cell (HSC) is a kind of nonparenchymal cells in the liver,which releases various collagenous fibers and cytoskeletal proteins,playing an important role in the pathophysiological changes of the liver.In normal,HSCs maintain normal tissue architecture via regulating the synthesis and degradation of extracellular matrix (ECM) proteins.During liver injury,HSCs were activated.Activated HSCs are the main cells that lead to the accumulation of extracellular matrix,which is the main reason of hepatic fibrosis,cirrhosis and liver failure.Therefore,lucubrating the role and mechanism of HSC in the progress of hepatic disease and investiating the HSC-related therapeutic strategies have practical significances for the prevention and treatment of liver injury and raise of patients' survival rates in clinical practice.

5.Practice and experiences in precision hepatectomy
Chinese Journal of Digestive Surgery 2014;13(6):412-414
With the wide application of liver transplantation techniques,rapid development of digital imaging medicine and continuous update of surgical implements,the theory of precision hepatectomy still keeps optimizing.Precision hepatectomy is not a surgical implement or surgical technique,but a concept of liver surgery emphasizing less bleeding,minimal invasion,fast recovery and long-term curative effect,which is updating and improving with the development of modern science.Much less intraoperative bleeding,shorter operation time,better postoperative recovery and long-term survival should be the chief pursuit and principle of precision hepatectomy.
6.The effect of high concentration oxygen to the lipid peroxidation of the gerbils subjected to cerebral ischemia and reperfusion
Chinese Journal of Pathophysiology 1989;0(06):-
Exposure of gerbils 120 min to a high concentration oxygen (HCO)atmosphere after 60 min cerebral ischemia resulted in a marked increase in cerebral malondialdehyde (MDA, 4.39?0.26 nmol/mg protein). Much less cerebral MDA was among the other groups (2.63?0.50 nmol/mg protein in sham-operated controls; 3.07?0.52 nmol/mg protein in gerbils exposed to HCO without ischemia; 2.96?0.41nmol/mg protein in ger. bils subjected to 60 min ischemia; 2.79?0.59nmol/mg protein in gerbils subjected to 60 min ischemia and 120 min reperfusion). The contents of cerebral water, sodium, increassd after 60 mln cerebral ischemia. The contents of TXB_2 increased, 6-Keto-PGF_(1?) decreased, the elevation of cerebral water and sodium were more obvious after 120 min repefusion following ischemia. There was no difference in these items except for MDA between the reperfusion groups within air and within HCO.The authors proposed the mechanism that HCO elevates the contents of cerebral MDH might be due to abnormal function of election transport chain of mitochondria.
7.The correlation of antiphospholipid antibody and factor Ⅻ deficiency in patients with retinal vein occlusion
Chinese Ophthalmic Research 2009;27(11):1019-1022
Objective Antiphospholipid antibody and factor Ⅻ deficiency are among the coagulation disorders that have been implicated in many thrombembolic events. The aim of this study was to investigate the prevalence of antiphospholipid antibodies and factor Ⅻ deficiency in patients with retinal vein occlusion (RVO). Methods The investigation was a case control study. The periphery blood was collected from a cohort of 33 consecutive patients with RVO and 30 age- and gender-matched normal subjects. Anticardiolipin antibody (ACA) was detected by ELISA as binding index (BI) =A value/standard A value. The lupus anticoagulant antibody was examined by APTT test and the activity of factor Ⅻ was detected. This study was approved by The Human Research Ethics Committee of this hospital, and written informed consent was obtained from all the subjects before initiation of any study protocol. Results The total positive rate of APA in RVO group was 24. 24% (8/33), showing a insignificant difference in comparison with control group (6. 67%, 2/30) (P = 0. 085). The positive rate of anticardiolipin antibody in RVO group was 18.18% (6/33), presenting an obvious enhance in control group (P = 0. 025) . Three patients in RVO group disclosed positive response for IgG-anticardiolipin antibody, one patient for IgM-anticardiolipin antibody, two patients for both isotypes IgG and IgM anticardiolipin antibodies, and two patients revealed positive reaction for lupus anticoagulant antibody. The presence of lupus anticoagulant antibody among the patients with ≤ 50 years and > 50 years was similar to that in age-matched controls (P =0. 160, P =0. 206). Factor Ⅻ deficiency was found in 14 of 33 patients(42. 42%) and in 4 of 30 controls(13. 33%) (P = 0. 013). The prevalence of factor Ⅻ deficiency among the patients with ≤50 years and > 50 years was similar to that in age-matched controls (P = 0. 206, P = 0. 052) . Conclusion Our results indicate that the prevalence of ACA and factor Ⅻ deficiency in RVO patients appears to be correlated.

Cancer Research and Clinic 2014;26(7):468-469,472
Objective To evaluate the diagnostic value of the combined detection of serum Fer,AFP and AFP-L3 in patients with primary hepatic cancer (PHC).Methods The serum levels of Fer,AFP and AFP-L3 were determined in 92 patients with PHC,84 patients with benign liver disease,and 45 control subjects.Results The PHC group serum Fer was (819.4±616.8) μg/L,AFP was (556.9±451.5) μg/L,AFP-L3 was (109.0±62.5) μg/L.The benign liver disease group Fer was (229.3±155.5) μg/L,AFP was (6.0±4.2) μg/L,AFP-L3 was (26.0±49.4) μg/L.The healthy control group Fer was (125.6±110.5) μg/L,AFP was (2.8±0.8) μg/L,AFP-L was (7.0±1.8) μg/L,there was significant difference between the three groups (all P < 0.01).The sensitivity of PHC group alone in detection of serum Fer was 85.9 %,the sensitivity of AFP was 71.0 %,the sensitivity of AFP-L3 was 83.7 %,the combined detection of Fer and AFP or AFP-L3 improved the sensitivity of the test to 90.2 % and 95.7 %,the three combined detection sensitivity was 98.9 %.Conclusion Combined detection of serum Fer,AFP and AFP-L3 is essential in the diagnosis of PHC.
