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 observe the clinical efficacy of acupoint application and moving cupping plus photo ionization treatment apparatus in treating hyperplasia of mammary glands. Method Sixty patients with hyperplasia of mammary glands were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupoint application and moving cupping plus photo ionization treatment apparatus, while the control group was by oral administration of Tamoxifen and Ru Pi San Jie tablets. The breast pain and lump score was observed before and after 2-month treatment, and the clinical efficacy was compared. Result The breast pain and lump scores were significantly changed in both groups after intervention (P<0.05). After intervention, there was no significant difference in comparing the breast pain and lump score between the two groups (P>0.05). The total effective rate was 96.7% in the treatment group versus 86.7% in the control group, and the difference was statistically significant (P<0.05). Conclusion Acupoint application plus moving cupping plus photo ionization treatment is an effective method in treating hyperplasia of mammary glands, and it can ease or reduce breast pain, and improve or reduce the lump.

Objective PRDX-2 of the basic level in patients with PCOS,and its correlation with cardiovascular risk factors.Methods Collected 78 cases of PCOS patients for POCS group,at the same time,choose healthy check-up 40 cases for control group.Determination of plasma Peroxiredoxin-2,blood sugar,glycosylated hemoglobin,cholesterol,triglycerides,and other biochemical indicators.Results Peroxiredoxin-2 level in PCOS group are higher than the control group(F=26.03;P<0.05).Peroxiredoxin-2 and cardiovascular risk factors exist correlation,including systolic blood pressure (r=0.213),diastolic blood pressure (r=0.380),fasting blood glucose (r=0.308),glycosylated hemoglobin (r=0.303),cholesterol (r=0.190),triglyceride (r=0.276),LDL-C (r=0.484) were positively correlated,and CRP (r=0.227),HDL-C negative correlation (r=0.355).Conclusion Determination of Peroxiredoxin-2 level can be used as evaluation of patients with PCOS risk factors for cardiovascular disease.

Objective To understand the effect of shenmai in treatment female patients with coronany heart disease.Methods 53 female patients with coronany heart disease were randomly divided into 2 groups(group A with normal treatment and shenmai,group B with normal treatment and water-soluble vitamins.Clinical effect was observed after 2 weeks.Results There are 13 cases effective in group A and 9 cases effective in group B,and the difference between the two groups is statistically significant (P ＜ 0.05).Conclusion It's better for female patients to uss shenmai.

The role of lipid-regulating capsule in the regulation of experimental dislipidemia was studied in SD rats. The SD rats were divided into 6 groups: group A (normal control)，group B to F (experimental hyperlipidemia). The rats in the groups C，D and E received the capsule in a daily dose of 2.5 g，5 g and 10 g/kg respectively for 3 weeks，while the rats in the group F received Simvastatin in a daily dose of 7.5 mg/kg for 3 weeks. By comparison with the group B after 3 weeks，the levels of plasma total cholesterol (TC) and low density lipoprotein (LDL-C) were very significantly decreased in the groups C，D，E and F(P<0.01)，the value of plasma total triglyceride (TG) was very significantly decreased in the groups D，E and F (<0.01)，and the level of high density lipoprotein was significantly increased in the groups C，D and E (P<0.05)，but very significantly increased in the group F (P<0.01). It was suggested that the therapeutic efficiency of the lipid-regulating capsule in low，middle and high dosage was the same as that in high dose of simvastatin for the SD rats with high plasma TC and LDL-C，and middle and high doses of the capsule had the same effect of simvastatin on the plasma TG.

Objective To discuss the application effects of fast track surgery treatment in hysterectomy. Methods 120 patients underwent hysterectomy. They were randomly assigned to two groups,namely,fast track sur-gery group(60 cases) and control group(60 cases ). two groups underwent separately fast track surgery mode and tradi-tional mode therapy. To observe the duration of passing flatus, the hospital stay, the aching time, the complication rate after operation between two groups. Results All patients got recovery. The duration of passing flatus(29.2±7.9) h,the aching time 96.7% (58/60)、the hospital stay( 3.9±2.5 )d of fast track surgery group were significantly shorter than the duration of passing flatus (50.3±15.8 ) h 、the aching time 8.3% (5/60)、the hospital stay (6.7±2.8 ) d of control group( allP<0.01 ). there was no severe complication in two groups. Conclusion Fast track surgery treat-ment mode could accelerate postoperative rehabilitation of hysterectomy patients. It shoud be popularized.

Objective To investigate the difference and treatment strategy of malignancy-associated dermatomyositis and other para-neoplastic neurological syndromes (PNS).Methods The clinical characteristics of a patient with malignancy-associated dermatomyositis and poly radiculoneuropathy was reported and the relevant literature was reviewed.Results Patients with dermatomyositis had increased risk of malignancies,and should routinely screened.Dermatomyositis and polyradiculoneuropathy was clinically similar,but could rarely be seen in the same malignant patient.Malignancy -associated dermatomyositis and PNS had similar pathogenesis.The treatment strategy of both was similar.Malignancy specific treatment should be initiated and immune suppressive agents should be prescribed concurrently.Conclusion Rheumatolgists should aware the association between dermatomyositis and potential underlying malignancies.Multiple para-neoplastic syndromes could be seen in the same patient,but the diagnosis should be considered as one.

Objective To detect the hypermethylation of HOXB6 gene in gastric cancer tissue and investigate the relationship between the gene expression and the clinics.Methods seven types of gastric cancer cell line and 73 cases of gastric cancer biopsy tissues were measured by combined bisulfite restriction analysis method.The gene expression and the re-expression after demethylation were detected by RT-PCR.Results Of 7 cell lines examined, 4 showed hypermethylation.The methylating status of HOXB6 was found to be correlated with loss of expression,which was restored by 5-aza-2＇-deoxycytidine treatment.We also find hypermethylation in 20/73(27.40%)case of cancer tissues but no one in non cancer tissue.Conclusion There are close relationship between hypermethylation and gene silencing in the HOXB6 gene of gastric cancer,There are also a gene re-expression after its demethylation.Hypermethylation of HOXB6 gene can be a tumor marker for gastric cancer diagnosis,and the agent of demethylation maybe a new antineoplastic drug.
