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 compare the chromatographic profiles and contents of three flavonoid aglycone equivalents (quercetin, genistein, and kaempferol) in the fruits of Sophora japonica var. pendula Loud. and the authentic Fructus sophorae, so as to provide a theoretical basis for using the fruit of Sophora japonica var. pendula Loud. as a substitute for Fructus sophorae. Methods: The fruits of Sophora japonica var. pendula Loud. were collected from different areas of Shijiazhuang in Winter. The flavonoids in the fruits were extracted by successive extraction with methanol. The acidic-hydrolyzed extracts were separated on a Diamonsil C18 column (150 mmX4.6 mm, 5μm). 0.4% phosphoric acid-methanol (50 ; 50, V/V) was used as mobile phase. The flow rate of mobile phase was 1.0 ml/min and the effluents were monitored at 360 nm. Results: The chromatographic profiles of the two fruit extracts were consistent basically. The contents of quercetin, genistein, and kaempferol in the fruits of Sophora japonica var. pendula Loud. were (0.30±0.07) %, (3.04±0.27) %, and (2.74±0.30)%, respectively, which were similar to those in the authentic Fructus sophorae. Conclusion: It is found that the contents of major flavonoid aglycones in the fruit of Sophora japonica var. pendula Loud. are similar to those in the authentic Fructus sophorae, making it a potential substitute for the Fructus sophorae.

Objective To explore the impact of overweight and obesity on flow mediated dilation (FMD) in adult people.Methods Intact clinical data of 183 healthy people, aged 30~65 in our hosipital were analyzed.According to BMI, all people were divided into obesity group (48 cases), overweight group(75 cases) and normal group (60 cases).FMD was detected by E tracing of ultrasonic.Weight, WC, BFP, baPWV, BP,FPG,CHO,HDL-C,LDL-C,TG and UC were observed at the same time.FMD of three groups were compared and the risk factors of FMD were analyzed.Results The level of FMD in the obesity group and overweight group was significantly higher than that in the normal group[(5.63±2.76)%,(6.45±2.54)% vs.(8.31±3.04)%](F=13.77,P<0.001);there was no statistically significant difference between the obesity group and overweight group (t=1.68,P>0.05).Age(β=0.078,95%CI: 1.004,1.164),BMI(β=0.465,95%CI 1.148,2.208),LDL-C(β=2.294,95%CI: 9.918,1.612) and UC(β=0.007,95%CI 0.986,1.000) were independent risk factors of decreased FMD(P<0.05).Conclusion Age, BMI, LDL-C and UC are independent risk factors of decreased FMD.

OBJECTIVE:To establish a method for the simultaneous determination of ethambutol(EMB)and isoniazid(INH) in children’s plasma. METHODS:After precipitated with acetonitrile,plasma samples were determined by UPLC-MS/MS method. Using lamivudine as internal standard,Waters ACQUITY? UPLC HSS T3 column was adopted with mobile phase consisted of ace-tonitrile-water(containing 0.05% formic acid and 15 mmol/L ammonium formate)in gradient mode at the flow rate of 0.2 ml/min. By ESI,positive ion detection was conducted in MRM mode. The monitoring transition ion-pair was m/z 205.2→116.0 for EMB, m/z 138.1→121.1 for INH and m/z 230.2→111.9 for internal standard. RESULTS:The linear range of EMB and INH was 10-5 000 ng/ml and 50-5 000 ng/ml,respectively;the limits of quantitation were 10 and 50 ng/ml;RSDs of inter-day and intra-day were all lower than 15% and relative recoveries were 98.7%-105.5%. Plasma concentrations of EMB and INH in 4 children with tuberculo-sis were 94.5-99.7 and 55.1-80.9 ng/ml. CONCLUSIONS:The method is rapid and sensitive,which suitable for children’s plasma concentration monitoring of EMB and INH and pharmacokinetic study.

Objective To research the reasonable perfusion flow of cardiopulmonary bypass during aortic arch procedure of patients with acute type A aortic dissection.Methods Forty patients suffered from acute Stanford type A aortic dissection had been divided into two groups randomly.Group A named traditional perfusion flow group,group B named modified perfusion flow group.Monitoring cerebral blood flow and cerebral tissue oxygen during deep hyperthermia circulatory arrest and antegrade aelective cerebral perfusion procedure by transcranial doppler(TCD) and near-infrared spectroscopy(NIRS).The concentration of S100 protein and lactic acid was measured at six time point.Results Statistical difference of mean blood flow velocity of MCA had been found between two group 3 min after total flow reperfusion.TOI was more tban 60％ during study in both of groups.S100 protein in group A was significantly higher than group B at T6,T7 and T8.Statistical difference of blood lactic concentration had been found between two groups,(4.88± 1.62) mmol/L in group A,(3.83± 1.48) mmol/L in group B,P ＜ 0.05.Safe consciousness time between two groups was difference,(7.36± 2.86) h in group A and (5.27± 3.11) h in group B,P ＜ 0.05.Conclusion Compared with the traditional perfusion flow,modified perfusion flow can provide sufficient cerebral perfusion and prevent the luxury perfusion.

OBJECTIVE:To analyze the effects of different disinfectants on results of antibiotics skin test,and to improve the accuracy of the judgment results of antibiotics skin test. METHODS:1 500 patients undergoing antibiotics skin test of penicillin and cephalosporin were randomly divided into group A and group B with 750 patients in each group. Group A was given 75% etha-nol disinfection,and group B was given iodine disinfection. The incidence of false positive results were compared after disinfected with 2 kinds of disinfectants. RESULTS:The incidence of false positive result in group B was lower than in group A,with statisti-cally significant difference (χ2=10.004,P<0.05). CONCLUSIONS:For skin disinfection of antibiotics skin test,iodine is better and safer than 75%ethanol.

Polymerase chain reaction was employed to amplify the HBV X gene from plasmid pCP10, and the product was cloned into pVR1012, then transfected HepG2 cells and cotransfected HepG2 cells with reporter plasmid pSV lacZ HBx protein produced by HepG2 cells was measured by ELISA method The activity of ? galactosidase was measured by a kit, which reflected the transactivating function of HBx protein The results showed that HepG2 cells transfected by pVR1012 X could express HBx protein The expression of ? galactosidase in HepG2 cells transfected by the pVR1012 X was 3 2 fold higher as that of control plasmid It is suggested that the recombinant plasmid pVR1012 X can be expressed in mammalian cell line, and has transactivating effect on SV40 early promoter

ObjectiveTo compare the effect of patient-controlled epidural analgesia (PCEA) and patient-controlled intravenous analgesia (PCIA) on pulmonary function in post-thoracotomy patients.Methods33 ASA Ⅰ～Ⅱ patients undergoing selective esophagectomy were randomly divided into the PCEA group (n=16, treated with morphine plus bupivacaine) and PCIA group (n=17, treated with morphine plus droperidol) for 3 days postoperatively. Pulmonary function indices including respiratory rate (RR), tidal volume (Vt), vital capacity (Vc) and pulse oximetry (SpO2) were recorded before operation and on the first 2 days after operation. Pain scores with visual analogue scale (VAS) at rest, deep breathing and with cough, and adverse effects were also recorded.ResultsRR increased, Vt , Vc and SpO2 decreased markedly in both groups postoperatively compared with the base line (P<0.01), but there were no significant differences between two groups. VAS scores were much lower in PCEA group, especially, when the patient was at deep breathing or during coughing (P<0.001).ConclusionPCEA is superior to PCIA in pain relief, but contributes no more than PCIA in improving pulmonary function in post-thoracotomy patients.
