Objective To explore the influence of aerobic exercise on plasma lipoprotein in overweight and obese PCOS women.Methods 12 obese and overweight patients with PCOS were selected.Before and after 12 weeks of aerobic exercise,the height,weight,BMI,WHR,body fat percentage and fasting blood samples of high-density lipoprotein(HDL),low density lipoprotein(VLDL),triglyceride and cholesterol levels were measured and detected.Results After 12 weeks of aerobic exercise,the BMI[(25.43±2.17)kg/cm2 vs.(22.27±1.57)kg/cm2,t=8.52],WHR[(0.864±0.021) vs.(0.831±0.019),t=2.99],fat rate[(33.76±5.36)% vs.(30.53±5.66)%,t=5.580],and triglyceride[(1.90±0.58)mmol/L vs.(0.95±0.51)mmol/L,t=7.400]were obviously decreased,the high-density lipoprotein cholesterol[(2.07±0.39)mmol/L vs.(3.31±0.48)mmol/L,t=3.352]was obviously increased,the differences were statistically significant (all P<0.05).Conclusion Obese and overweight PCOS women can lose weight through aerobic exercise,so as to adjust lipoprotein spectrum and improve health.

Objective To investigate the single nucleotide polymorphism of 5,10-methylenetetrahy-drofolate reduetase gene and its association with the treatment of methotrexate in rheumatoid arthritis (RA).Methods A total of 184 patients with RA were divided into methotrexate (MTX) treatment group, MTX+other DMARDs treatment group, and treatment with other DMARDs but not MTX group. The clinical and laboratory data were evaluated before treatment and 24 weeks later. Efficacy and toxieities of each medication were also analyzed. Real-time fluorescent quantitative PCR was conducted to test gene mutations in RA patients and 100 healthy controls. Results There was no significant difference in the frenqueney of 677CC,CT, "IT and 1298AA, AC, CC between RA patients and the healthy controls. There was significant difference in the frenqueney of 677CC, CT, Tr between RA patients with cardiovascular eomplieations and the healthy controls. In the MTX treatment group, there was significant difference in the frenqueney of 1298AC, CC between the group in which MTX was effective and the other groups in which MTX was not effective, the occurrence rate of side effects of MTX in the patients with 677TT was higher than those without mutation(CC).In MTX+other DMARDs group, the occurrence rate of side effects of MTX in the patients with 677TT and CT was higher than that without mutation (CC). Conclusion There is no relationship between the pathogenesis of RA and the 677C/T, 1298A/C mutation of MTHFR gene. MTHFR gene 677C/T mutation is probably one of the genetic risk factors for cardiovascular complications of RA patients and the side effects of MTX. MTHFR gene 1298A/C allel is associated with the efficacy of MTX.

Objective To detect the plasma level of osteopontin (OPN)in systemie lupus erythematosus (SLE) patients,and its correlation with disease activity as well as organ damage was analyzed.Methods The plasma level of osteopontin was measured by enzyme-linked immunosorbent assay in 68 SLE patients and 36 healthy controls.Results The plasma level of OPN was significantly higher in SLE Datients than in healthy control group(P＜0.01).In SLE patients,the plasma OPN level was significantly higher in patients with renal damage than in patients without renal damage(P＜0.01).Patients with lung interstitial disease and gastrointestinal tract involvement,their plasma level of OPN was significantly higher than those of patients with inactive lupus (P＜0.01).The plasma level of OPN correlated positivelv and significantly with SLEDAI score(r=O.523,P＜0.001)and 24-hour urine protein excretion(r=0.403,P=0.001),but negativelycorrelated with serum C3 level (r=-0.398,P=0.001).There was no correlation between the Dlasma level of OPN and anti-dsDNA antibody,Sm antibody,erythrocyte sedimentation rate,serum IgG,IgA,IgM levels(P＞0.05 ). Conclusion OPN may be involved in the pathogenesis of SLE,and may be a potential marker for dis-ease activity and organ damage.

Purpose:To detect the expression of MDR 1 / P-gp,C-erbB-2 in breast cancer and study the correlation between MDR 1 /P-gp and C-erbB-2. Methods:Expression of MDR 1 gene was measured with the flu orogenic quantitative RT-PCR method in 57 cases of breast cancer and 20 cases o f control group (including 10 cases of benign breast lesions and 10 cases of adj acent breast tissues). In addition, immunohistochemical analyses was used to det ect the expression of P-gp and C-erbB-2 protein in the above mentioned tissu es. Results:The amplification rate of MDR 1 gene and the expre ssion of P-gp protein in breast cancer group was 50.88% (29/57) and 42.11% (24/ 57), which had a significient difference as compared to the control group. The a mplification of MDR 1 gene were higher than the expression of P-gp protein ,there was close correlation between them but not complete correspondence.The p ositive rate was 28.07%(16/57) in detecting the overexpression of C-erbB-2 pro tein in breast cancer group, nevertheless, no positive case was found in the con trol group. The expression of MDR 1/P-gp was also correlated with the over expression of C-erbB-2. Conclusions:Multidrug resistance gene1(MDR 1)and protoonco gene C-erbB-2 were co-expressed in breast cancer,and their expression were po sitively related. The expression of above mentioned two genes have a relationshi p with multidrug resistance in breast cancer.

Objective To study cyclooxygenase-2 (COX-2) expression levels in cervical, endometrial and ovarian cancers as well as their originated normal tissues. Methods Semiquantitative immunofluorescent assay (IFA) was used to detect COX-2 expression levels in cervical squamous cell carcinoma (n=12),endometrial adenocarcinoma (n=13),and ovarian serous adenocarcinoma (n=9). COX-2 expression levels in normal cervical (n=14),endometrial (n=15),and ovarian (n=13) tissues were simultaneously detected as control. Results Normal cervical tissues expressed COX-2 more frequently than cervical cancers (50% vs 23%), but the difference was not signicant (P=0.247). The positive rate of COX-2 expression was significantly higher in endometrial adenocarcinomas (69%) than that in normal endometrium (7%) (P

Objective To assess the role of matrix metalloproteinase-9(MMP-9) and interleukin-6 (IL-6) of amniotic fluid (AF) in predicting infection of amniotic cavity. Methods Eighty-four cases of sigle foetus women with premature delivery, premature rupture of foetal membranes,or suspicious infection of amnitotic cavity were enrolled in this study. AF was obtained by transabdominal amniocentesis before starting any treatment.Infection of amniotic cavity was defined when AF bacterial culture was positive. The contents of glucose, leukocytes, MMP-9,and IF-6 in AF were determined. Results The levels of MMP-9 and IL-6 in AF were significantly higher in women with infection of amniotic cavity than those in women without. In women with infection of amniotic cavity, MMP-9 level was significantly correlated with IL-6 level (r=0.813,P

Peroxisome proliferators -activated receptors γ(PPARγ)agonist is a kind of drugs that is widely used in the treatment of type 2 diabetes,also shows effects on hypertensive disease,regulating blood lipid metabolism, anti -atherosclerosis and inhibiting inflammatory response.In recent years,good effects of PPARγagonist have been found on different animal models of asthma,and production of proinflammatory cytokines can significantly be reduced. Airway remodeling can be reduced,and airway hyper responsiveness can be inhibited by PPARγagonist that provide theoretical basis on new drugs for asthma.The mechanism of bronchial asthma cured by PPARγagonists are reviewed briefly.
