Objective: To study the relation among inducible nitric oxide synthase(iNOS), endothelial nitric oxide synthase(eNOS) and vascular endothelial growth factor (VEGF)in oral squamous cell carcinoma(OSCC) and their relation to clinical pathology and angiogenesis.Methods:OSCC tissue specimens were surgically obtained from 64 patients,the expression of iNOS,eNOS and VEGF in the samples were studied by immunohistochemistry technique. Microvessel density(MVD) was measured by counting the endothelial cells stained with anti-FⅧRAg antibody. Results: ①Positive VEGF and iNOS and eNOS immunostaining was detected in 39(60.94%),42(65.63%)and 45( 70.31%)of the cases respectively.②Expression of VEGF was significantly related to that of iNOS(P05).③MVD in OSCC tissue was positively correlated with the expression of VEGF and iNOS(P05).④VEGF expression was positively correlated to the pathological grade of OSCC(P0.05).Conclusion:iNOS,rather than eNOS, plays a positive role in OSCC development.iNOS and VEGF have a positive correlation in angiogenesis of OSCC.

OBJECTIVE:To observe the effects of Compound biejia ruangan tablets combined Entecavir tablets on liver func-tion and hematoidin of patients with chronic hepatitis B(CHB)blood stasis syndrome. METHODS:Totally 110 patients with CHB blood stasis syndrome were selected from Neijiang Second People's Hospital,the Affiliated Hospital of Southwest Medical Univer-sity and Yibin First People's Hospital during Jan.-Dec. 2015. They were divided into control group and observation group by strati-fied blocked randomitation,with 55 cases in each group. Control group was given Entecavir tablets 0.5 mg,po,qd;observation group was additionally given Compound biejia ruangan tablets 2.0 g,po,tid. Both groups received treatment for 12 months. TCM syndrome scores,the levels of liver function indexes(AST,ALT,ALP,GGT),serum bilirubin(TBIL,DBIL,IBIL),liver fi-brosis indexes(LN,HA,PⅢP,Ⅳ-C)and Fibroscan(FS)were observed in 2 groups before and after treatment. The occurrence of ADR was recorded. RESULTS:In observation group,2 patients withdrew from the study,and 3 patients of control group with-drew from the study. Before treatment,there was no statistical significance in TCM syndrome scores,the levels of liver function in-dexes,serum bilirubin,liver fibrosis indexes and FS between 2 groups(P>0.05). After treatment,TCM syndrome scores,the lev-els of TBIL,IBIL,LN,HA,PⅢP,Ⅳ-C and FS in 2 groups were significantly decreased,while DBIL level was increased signifi-cantly,and the observation group was significantly better than control group,with statistical significance(P<0.05). The levels of AST and ALT in observation group were decreased significantly,while the levels of ALP and GGT were increased significantly, and the observation group was significantly better than control group,with statistical significance(P<0.05).
