OBJECTIVE:To analyze the utilization and variation tendency of oral hypoglycemic agents in Wuhan area,and to provide reference for drug selection and enterprise production and sale. METHODS:The utilization of oral hypoglycemic agents in 34 hospitals from Wuhan area during 2011-2013 was analyzed statistically in respects of consumption sum,DDDs and DDC etc. RESULTS:The consumption sum and DDDs of oral hypoglycemic agents increased by 20% and 7% respectively year by year. Acarbose had a market share of over 40%. The drug use frequency of metformin ranked the second place only to acarbose. DPP-4 inhibitor had a promising future,with a consumption sum proportion of more than 10%,while the market share of traditional Chi-nese medicine had fallen below 3%. Except for repaglinide,gliclazide,glimepiride,Xiaoke pills,etc.,the selling of other medica-tions are consistent with the user. CONCLUSIONS:The utilization of oral hypoglycemic drugs is basically rational in 34 hospitals from Wuhan area during 2011-2013.

OBJECTIVE:To study tanshinone ⅡA inhibiting the proliferation and migration induced by homocysteine(Hcy)of rat aortic vascular smooth muscle cells(VSMCs)and its signal pathway. METHODS:VSMCs were selected for the following ex-periments. In order to validate TanshinoneⅡA inhibiting the proliferation and migration induced by Hcy of VSMCs,VSMCs were di-vided into control group,Hcy group(1 000μmol/L),TanshinoneⅡA low-dose,medium-dose and high-dose groups(5,10,20 μg/L). In mechanism study test,VSMCs were divided into control group,TanshinoneⅡA group(20 μg/L),rapamycin group(20 nmol/L), MHY1485 group(10μmol/L),TanshinoneⅡA+rapamycin group(TanshinoneⅡA,20 μg/L+rapamycin,20 nmol/L),TanshinoneⅡA+MHY1485 group (TanshinoneⅡA,20 μg/L+MHY1485,10 μmol/L). In validation test of P70S6K and p-P70S6K pathway expres-sion,rapamycin and MHY1485 were used for inhibitory test and activation test,respectively. The proliferation of VSMCs was de-termined by ELIASA,and Transwell chambers and wound healing test were employed to test the migratory ability of VSMCs. West-ern blotting were used to investigate the expressions of P21,P27,MMP-2,MMP-9,P70S6K and p-P70S6K in VSMCs. RE-SULTS:In validation test,compared with control group,24,48 h absorbance,migration area,the number of VSMCs penetration and the expression of MMP-2,MMP-9 and p-P70S6K increased significantly,while the expression of P21 and P27 decreased sig-nificantly(P<0.01). Compared with Hcy group,48 h absorbance of TanshinoneⅡA low-dose group,24,48 h absorbance and the expression of MMP-2 of TanshinoneⅡA medium-dose and high-dose groups,migration area,the number of VSMCs penetration, the expression of MMP-9 and p-P70S6K in low-dose,medium-dose and high-dose groups all decreased significantly;the expres-sion of P21 and P27 increased significantly in TanshinoneⅡA medium-dose and high-dose groups(P<0.01);there was no statisti-rapamycin group,while 24,48 h absorbance increased significantly in MHY1485 group(P<0.01). Compared with TanshinoneⅡA group,24,48 h absorbance decreased significantly in TanshinoneⅡA+rapamycin group,while 12,24,48 h absorbance,migration area and the number of VSMCs penetration increased significantly in TanshinoneⅡA+MHY1485 group (P<0.01). In inhibitory test,compared with control group,the expression of p-P70S6K decreased significantly in TanshinoneⅡA group (P<0.01);com-pared with TanshinoneⅡA group,the expression of p-P70S6K decreased significantly in rapamycin group and TanshinoneⅡA+rapa-mycin group(P<0.01);in activation test,the expression of p-P70S6K decreased significantly in TanshinoneⅡA group(P<0.01), compared with TanshinoneⅡA group,the expression of p-P70S6K increased significantly in MHY1485,TanshinoneⅡA+MHY1485 group (P<0.01). CONCLUSIONS:TanshinoneⅡA can inhibit the proliferation and migration of VSMCs by suppressing mTOR/P70S6K signal pathway.

Objective: To observe influence of aerobic exercise on blood pressure in patients with white coat hypertension (WCH). Methods: A total of 51 newly diagnostic WCH patients were randomly divided into exercise group (n=26) and WCH control group (n=25). Patients in exercise group received aerobic exercise training (walking on flat ground by constant speed, twice a day, 50~80 min each time for three months); The WCH control group did not exercise. Office blood pressure (OBP) and 24h ambulatory blood pressure monitoring (ABPM) were measured in both groups before and three months after treatment. Results: There were no significant difference in indexes of OBP and ABPM between two groups before treatment (P>0.05). After three months, compared with before treatment, indexes of OBP and ABPM significantly decreased in exercise group and they were significantly lower than those of WCH control group in OBP [OSBP: (132.54±17.60) mmHg vs. (143.68±20.35) mmHg, ODBP: (89.12±18.39) mmHg vs. (92.75±17.24) mmHg] and ABPM [ mSBP：(121.57±20.86) mmHg vs. (128.06±19.45) mmHg, mDBP：(76.24±15.28) mmHg vs. (84.55±17.31) mmHg; dSBP：(124.27±22.50) mmHg vs. (130.85±24.61) mmHg, dDBP：(77.95±18.42) mmHg vs. (82.36±17.59) mmHg], P<0.05~0.01. Conclusions: Aerobic exercise can significantly improve blood pressure in patients with white coat hypertension.

The incidence rate of hepatocellular carcinoma (HCC) is increasing around the world and tends to decrease in East Asia and several regions in China;however, China still has higher incidence rate and mortality rate of HCC than most countries.Studies have shown that long-term antiviral therapy can inhibit HBV replication to a very low level or help patients with HCV infection achieve sustained virologic response, which can further reduce the incidence rate of virus-related HCC.New evidence suggests that compared with nucleos(t)ide analogues, PEG-IFNα has a better effect of secondary prevention.Studies also indicate that interferons play an important role in tertiary prevention of virus-related HCC.This article reviews the epidemiological studies on virus-related HCC in recent years and the role of antiviral therapy in second and tertiary prevention and points out that adequate and effective antiviral therapy is the basis for preventing the development and recurrence of HCC.

Objective To observe the change of serum anti-brain antibodies after cardiopulmonary resuscitation,and investigate the clinical significance.Methods A total of 27 cases of cardiopulmonary resuscitation after cardiac arrest patients with success and survival more than 12 weeks were divided into two groups according to Glasgow Coma Scale (GCS) score:mild and moderate group with GCS score ≥ 8 scores (12 cases) and severe group with GCS score≤7 scores (15 cases).The serum anti-brain antibody levels at 3,7 days and 2,3,4,12 weeks after recovered in the spontaneous circulation (ROSC) was compared between two groups,and compared with control group (15 cases of healthy persons).Results The serum anti-brain antibody levels at 3,7 days and 2,3,4,12 weeks after ROSC were significantly higher than those in control group [(1.34 ± 0.23),(1.30 ± 0.27) kU/L vs.(0.28 ± 0.05) kU/L,(1.38 ± 0.33),(1.44 ± 0.30) kU/L vs.(0.28 ±0.05) kU/L,(1.44 ±0.31),(1.51 ±0.33) kU/L vs.(0.28 ±0.05) kU/L,(1.53 ±0.27),(1.67 ±0.36) kU/L vs.(0.28 ±0.05) kU/L,(1.72 ±0.25),(1.93 ±0.44) kU/L vs.(0.28 ±0.05) kU/L,(1.98 ±0.45),(2.15 ±0.52) kU/L vs.(0.28 ±0.05) kU/L],and there were significant differences (P＜ 0.01).The serum anti-brain antibody levels in severe group were significantly higher than those in mild and moderate group,and there were significnat differences (P ＜ 0.05).Conclusions The serum anti-brain antibody levels after cardiopulmonary resuscitation rise significantly.Anti-brain antibody may be used as a biochemistry marker to judge degree and prognosis of brain injury with patients after cardiopulmonary resuscitation.
