Objective To research the relationship between the expression of PAI-1 and the clinical characteristics of the endometrial carcinoma.Methods We detected the level of the serum PAI-1 by ELISA in the patients with endometrial carcinoma,the patients with endometrial hyperplasia and the patients with normal endometrium.The expression of PAI-1 in endometrial carcinoma and normal endometrial tissues was observed by immunohistochemistry.Results The concentration of serum PAI-1 in patients with endometrial carcinoma was 18.64 ± 6.22 μtg/L,significantly higher than those of patients with endometrial hyperplasia (6.94 ± 2.87) μg/L and patients with normal endometrium (6.68 ± 2.13)μg/L (P=0.00).The expression rate of PAI-1 was 68.2％ (15/22) in endometrial carcinoma tissue,and 8.3％ (2/24) in normal endometrial tissue (P=0.00).Compared with the early endometrial carcinoma,the expression rate of PAI-1 in the advanced endometrial carcinoma was significantly higher (6/6 w 9/16,P=0.03).Conclusions The expression level of PAI-1 may be related to the stage of the endometrial carcinoma.

Objective:To observe and compare the therapeutic effect of metoprolol by routine increasing dose method and rapid titration method on acute myocardial infarction (AMI).Methods:A total of 60 inpatients,who were di-agnosed with AMI within 24h and without contraindications for metoprolol,were randomly divided into two groups:routine therapy group (received metoprolol using routine methods,the dose was added in seven days)and rapid ti-tration group (metoprolol was added in three days using titration).The dosage maintained with 190 mg/d after both groups reaching the target dose of 190mg/d;then therapeutic effects were observed in both groups.Results: ①There were no re-myocardial infarction,rehospitalization caused by heart failure and sudden death etc.in both groups;② Patients received echocardiography in outpatients after three months.Compared with routine increasing dose group,there was significant reduction in left ventricular end-diastolic diameter [LVEDd,(55.00±7.56)mm vs.(50.00± 5.81)mm]and significant rise in left ventricular ejection fraction [LVEF,(49.13 ± 10.18)% vs. (57.84±10.34)%]in rapid titration group,P <0.01 both.Conclusion:Rapid titration method could make the pa-tients rapidly reach the targeted dose of metoprolol and inhibit renin release earlier,block the renin-angiotensin sys-tem,and improve myocardial remodeling and cardiac function.

Objective To evaluate the relationship between thyroid autoimmunity and the risk of preterm birth. Methods Literature search was done among PubMed, Embase, Wanfang Medical Database, China Academic Journal Network Publishing Database and China Biology Medicine disc from Jan. 1st 1980 to July 31st, 2015. (1) Literature were extracted according to inclusion and exclusion standards, and the quality of the extracted literature were evaluated by Newcastle-Ottawa Scale (NOS). (2) Meta-analysis was performed by RevMan 5 software formulated by using the Cochrane library databases. Various heterogeneity of the research was inspected firstly. According to the results of the inspection a certain effect model was selected (including fixed effects model, the random effects model) to be utilized in merger analysis. In this study pregnant women with both thyroid peroxidase antibodies (TPO-Ab) and thyroglobulin (TG-Ab) positive were defined as thyroid antibody positive pregnant women. Pregnant women with only TPO-Ab positive were defined as TPO-Ab positive pregnant women. Then the relationship of antibody positive and the risk of a pre-term birth was analyzed respectively. Results (1) Ten cohort studies were enrolled, of which NOS scale score were 7 or higher. All the studies are of medium quality and above. A total of 1 322 cases of preterm birth occurred among 19 910 pregnant women. (2) Positive thyroid autoantibodies did not increase the risk of preterm birth in euthyroid pregnant women (OR=1.41, 95%CI:0.83-2.40, P=0.200) or in pregnant women with hypothyroidism (OR=0.68, 95%CI: 0.32-1.44, P=0.310). Positive TPO-Ab in euthyroid pregnant women increase the risk of preterm birth significantly (OR=2.08, 95%CI:1.09-3.97, P=0.030), but positive TPO-Ab in pregnant women with hypothyroidism did not increase the risk of preterm birth significantly (OR=1.21, 95%CI:0.65-2.24, P=0.550). Conclusion Positive TPO-Ab is an independent risk factor of preterm birth in euthyroid pregnant women.

ObjectiveTo explore the effects of glycomacropeptide (GMP) in human milk and formula milk on proliferation ofbifidobacterium infantis and their dose-response relationship.Methods Casein was isolated from the milk of 30 healthy postpartum women from Guangzhou Women and Children's Medical Center in September 2014, and hydrolyzed by rennet to obtain GMP, which was then purified by ultrafiltration and ion exchange chromatography. Human milk GMP and cow milk GMP (0, 250, 500, 1 000, 1 500, 2 000 and 3 000 mg/L) were added tobifidobacterium infantis liquid medium, and cultured under anaerobic conditions. Concentration of bacteria was measured by turbidimetric microplate assay (detection of OD600 nmvalue of medium). Difference of proliferative activities ofbiifdobacterium infantis in human milk GMP and cow milk GMP was compared with independent samplest-test.ResultsPurified human milk GMP concentration was 1 712.20 mg/L, with a purity of 80.3%. Increasing the cow milk GMP initial concentration in the culture medium at 250-2 000 mg/L could increase the concentration and proliferation rate ofbiifdobacteria infantis. When cultured at 36 h with GMP of various concentrations, the proliferation ofbiifdobacteria infantis maintained at a logarithmic phase. Therefore, 36 h was chosen as the test time point to compare the proliferation ofbifidobacterium infantis. At 36 h, when GMP in the medium was 1 000, 1 500, 2 000 and 3 000 mg/L, concentrations ofbiifdobacteria infantis in human milk GMP were 2.255±0.036, 2.583±0.088, 2.877±0.080 and 3.219±0.081, respectively, which were significantly higher than those in cow milk GMP (2.115±0.053, 2.312±0.064, 2.542±0.090 and 2.894±0.076;t=4.867, 5.569, 6.192 and 6.516; allP<0.01).Conclusions Both human milk GMP and cow milk GMP can promote the proliferation ofbiifdobacterium infantisin vitro, and the proliferative activity in human milk is greater than in cow milk at the same concentration of GMP.

Objective To study the eorrelation between the plasma cardiotrophin-1(CT-1)level and cardiac function of patients with diabetic cardiopathy.Methods Using the Biotin-StreptAvidin-enzyme-linked immunosorbent assay(BSA-ELISA),the level of plasma CT-1 jn 35 normal controls,40 patients with type 2 diabetes and 60 patients with diabetic cardiopathy was measured.The relation to heart function was observed.Results The difference of plasma CT-1 level in the three groups was significant(all P＜0.05).The level of plasma CT-1 in diabetic cardiopathy group was apparently higher than that of type 2 diabetes group and normal controls(all P＜0.01);The level in type 2 diabetes group was significantly higher than that of normal controls(P＜0.01).The level of plasma CT-1 elevated with the worsening of heart failure(NYHA classification).The level of plasma CT-1 was correlated with EF(r=0.669,P＜0.01);LAD(r=0.528,P＜0.01);PVE(r=0.502,P＜0.01);CK-MB(r=0.312,P＜0.01);TG(r=0.187,P＜0.05);DBP(r=0.158,P＜0.05)o Stepwise regression analysis revealed that EF and LAD were the most significant agents affecting the plasma CT-1.Conclusion The plasma CT-1 level could reflect the state of cardiac function of diabetic cardiopathy patient,it could help to diagnose diabetic cardiopathy earlier.
