Objective To evaluate the improvement of endothelial function by folic acid and B vitamins supplement in patients of coronary artery disease who undergone interventional therapy.Methods Eighty patients of coronary artery disease who undergone interventional therapy were divided into two groups:control group(40 cases,routine treatment)and treatment group(the others,with routine treatment plus orally taken folic acid and B vitamins,folic acid 15mg/d,vitamin B_(12)75μg/d,vitamin B_6 30mg/d,for 6 months).Plasma homocystine (Hcy)was measured by fluorescence polarization immunoassay and flow-mediated dilation(FMD)of the brachial artery was assessed by high resolution ultrasound before and after 6 months.Results After treatment,the levels of Hcy decreased obviously in treatment group[(8.62±3.51)μmol/L]than that in control group[(12.96±4.62)μmol/L](P<0.01).The FMD was increased significantly in treatment group[(4.22±1.46)%vs (8.74±1.51)%,P<0.01].Conclusions Routine treatment,including aspirin and stafins,significantly improves endothehal function in patients with coronary artery disease.Folic acid and B vitamins supplement may exert beneficial effects on patients with coronary artery disease.

Objective To evaluate the value of laparoscopy in the treatment of intramural myoma.Methods Totally 120 cases of intramural myoma were randomly divided into laparoscopy(n=52)and open groups(n=68).Clinical data,including operation time,intraoperative blood loss,rates of postoperative pyrexia and postoperative complications,length of hospital stay and follow-up,were compared between the two groups.Results Compared to the open group,the laparoscopy group had significantly longer operation time (106.3?54.9)min vs(66.5?7.3)min,t=5.918,P=0.000],less blood loss 10-300 ml(median,50 ml)vs 20-200 ml(median,50 ml),Z=-1.998,P=0.046],lower rate of postoperative pyrexia 7.7%(4/52)vs 30.9%(21/68),?2=9.608,P=0.002],similar rate of postoperative complications 3.8%(2/52)vs 8.3%(3/36),?2=0.000,P=1.000],shorter hospital stay (7.5?1.4)d vs(10.4?1.2)d,t=-12.201,P=0.000],and similar length of follow-up (9.7?2.3)months vs(9.6?1.8)months,t=0.267,P=0.790] and rate of normal menses 94.4%(17/18)vs 90.5%(19/21),?2=0.000,P=1.000].Conclusions Laparoscopy is as effective as open surgery for intramural myoma.While the laparoscopy leads to better postoperative recovery than the open surgery.

Objective To evaluate the clinical significance of laparoscopic operations in the treatment of ovarian endometriosis cysts. Methods We compared clinical data between 52 cases of laparoscopic operation for ovarian endometriosis cysts (Laparoscopy Group) and 75 cases of open operation for ovarian endometriosis cysts (Open Group) in the same period. Results The operation time was significantly shorter in the Laparoscopy Group (61 4?9 3) than in the Open Group (72 6?7 1) ( t =7 692, P =0 000). The time to first flatus was significantly earlier in the Laparoscopy Group (25 3?4 1 h) than in the Open Group (49 8?6 9 h) ( t =22 935, P =0 000). The postoperative pyrexia rate in the Laparoscopy Group (9/52) was significantly lower than that in the Open Group (31/75) ( ? 2 =8 216, P =0 004). There were no significant differences on the remission rate of dysmenorrhea between the Laparoscopy Group (26/37) and the Open Group (34/51) ( ? 2=0 128,P =0 818) and on the postoperative pregnancy rate between the Laparoscopy Group (5/22) and the Open Group (7/25) ( ? 2 =0 171, P =0 747). Conclusions Laparoscopic operation for ovarian endometriosis cysts is as effective as open operation, being an ideal alternative.

ObjectiveTo explore the inflammatory factors C-reactive protein (CRP),interleukin (IL)-6,tumor necrosis factor (TNF)-α and white blood cell (WBC) count differences between acute myocardial infarction(AMI ) thrombolysis treatment and unthormbolysis treatment,and find out the relevance between the inflammatory factors and the prognosis.MethodsAccording to the condition of accepting AMI thrombolysis treatment,the 229 patients of AMI were divided into the thrombolysis group( 131 cases) and the unthrombolysis group(98 cases).The levels of myocardial troponin I (cTnI),creatine kinase(CK),creatine kinase isoenzyme-MB (CK-MB) were detected at the time of patients sent into the hospital for the immediate,6-hour later and 24-hour later.After 6-month's follow-up,prognosis was compared between two groups.ResultsTwenty-seven cases lost in the thrombolysis group.One case died within 6 months and the mortality was 1.0％(1/104) in the thrombolysis group,and 6 cases died within 6 months and the mortality was 6.1％(6/98 ) in the unthrombolysis group.There was significant difference between two groups (P ＜ 0.05 ).The levels of CK,CK-MB in the thrombolysis group advanced,and compared with that in the unthrombolysis group,there were significant differences (P ＜ 0.05 ).The levels of TNF-α,IL-6 in the thrombolysis group were significantly higher than those in the unthrombolysis group (P＜ 0.05),and CRP and WBC count had no significant differences between two groups (P ＞ 0.05).The repatency rate was 79.4％( 104/131 ) in the thrombolysis group,the levels of TNF- α,IL-6 in repatency patients were higher than those in non-repatency patients.There were significant differences(P ＜ 0.05 ).ConclusionsThe thrombolysis is an effective way to cure AMI.The increase of TNF- α,IL-6 after the thrombolysis is considered to be related to reperfusion injury,and CRP,IL-6,TNF-α and WBC count can forecast the inflammation of myocardial necrosis and take an impotant role in predicting the prognosis of the AMI.The antiinflammatory and antioxidation treatment is significant to improve the prognosis of the AMI.

Highly active adherent LAK cells (A-LAK) with monocytes depleted by phenylalahine methyl ester (PME) were cultured from peripheral blood lymphocytes of patients with hepatocellular carcinoma (HCC). Results showed that A-LAK cells cultured in about 14 days had expanded better and faster than that of nonadherent LAK cells (NA-LAK) with their greatest expansion varied from 23 to 243 fold .A-LAK cells showed a trend of increase in TH cell subgroup and decrease in Ts cell sub-group as well as significant difference of TH/TS ratio. The IL-2R expression increased from 34.1%to 64.3%. A-LAK cells had a higher cytotoxicity (64.6%)than that of NA-LAK cells (42.8%).Further clinical application of A-LAK cells may improve biotherapeutic effect on HCC patients compared with that of NA-LAK cells .
