OBJECTIVETo explore effective pretreated methods for hydrosalpinx before frozen embryo transfer (FET).
METHODSA randomized controlled study was performed on 229 FET cycles of hydrosalpinx patients. They were assigned to two groups by random digit table, Group A (94 cases), Group B (89 cases), and Group C (46 cases). Patients in Group A received transvaginal aspiration of hydrosalpinx combined with auricular point sticking. Those in Group B received transvaginal aspiration of hydrosalpinx group. Those in Group C received no transvaginal aspiration of hydrosalpinx. Pregnancy outcomes of FET, endometrial and subendometrial blood flow distribution on the embryo transfer day were compared among the three groups.
RESULTSThere was no statistical difference in the endometrial thickness on FET day, the number of transfer embryos, the number of transferred good quality embryos among the three groups (P > 0.05). The clinical pregnancy rate and the embryo implantation rate were significantly higher in Group A than in Group C (P < 0.05), and the clinical pregnancy rate was significantly higher in Group A than in Group B (P < 0.05). The early abortion rate and the transfer cycle cancel rate were significantly lower in Group A than in Group C (P < 0.05). Type A endometrial and subendometrial blood flow distribution was dominant in Group A, which was significantly higher in Group A than the rest two groups (P < 0.05). Type A distribution rate was also significantly higher in Group B than in Group C (P < 0.05).
CONCLUSIONTransvaginal aspiration of hydrosalpinx combined with auricular point sticking before FET could improve the endometrial receptivity and improve outcomes of IVF.

OBJECTIVETo examine the plasma lipid level and distribution of dyslipidemia in workers of Chongqing enterprises and institutions.
METHODSBy using cluster sampling method, 20 000 workers of Chongqing enterprises and institutions aged 18 to 60 were selected as target population from January to October, 2009. We conducted questionnaire survey, physical and laboratory examinations including total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Workers were divided into 18 - 29 years old group, 30 - 39 years old group, 40 - 49 years old group and 50 - 60 years old group. Characteristic and distribution of dyslipidemia were analyzed.
RESULTSTotal cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were significantly different in various age group (all P < 0.01). TC, TG, HDL-C and LDL-C levels in the 30 years and over groups were all significantly higher than in the under 30 years old group(all P < 0.01). The TG levels in the 40 - 49 years old group and the 50 - 60 years old group were similar (P > 0.05). After adjusting for age, TC, TG, HDL-C and LDL-C levels in males were all significantly higher than in females (all P < 0.01). The incidence of dyslipidemia in this population was 35.01% and significantly higher in males than that of females (58.27% vs. 11.01%, P < 0.01). The incidence of dyslipidemia increased with aging (P < 0.01).
CONCLUSIONSThe prevalence of dyslipidemia is high in Chongqing enterprises and institutions. The incidence of dyslipidemia is higher in males than in females and higher among the 30 years and over workers than that of under 30 years old workers.

OBJECTIVEHLA-DMA and DMB are non-classical genes whose product (DM molecules) plays an important role in antigen presentation. Our present study was designed to investigate the relationship between human leukocyte antigen-DMA, -DMB and clinical status heterogeneity of type 1 diabetes.
METHODSA total of 80 children (male 36, female 44) with type 1 diabetes were selected as research subjects. Diagnosis of type 1 diabetes was made according to WHO criteria. The range of age at onset of type 1 diabetes was 2.5 - 14 years. Ninety-one healthy adult blood donors were selected as normal controls. Polymerase chain reaction and dot blot hybridization techniques were used to classify DMA and DMB alleles. Patients with type 1 diabetes were classified into different groups according to different clinical status, including sex, age of onset, ketosis onset situation on diagnosis, remained function of islet beta cell, etc. Then distribution of DM susceptive alleles and heterodimer in different clinical groups were studied.
RESULTSThe frequencies of DMA * 0103 and DMB * 0103 alleles in patients were significantly increased (50% vs. 8%, 43% vs. 22%, respectively), these two alleles confer susceptibility to type 1 diabetes in Chinese. The frequencies of DMA * 0103/DMB * 0102, DMA * 0103/DMB * 0103 and DMA * 0103/DMB * 0101 heterodimers were also increased in the patients. The above heterodimers confer predisposition to type 1 diabetes. Both DMB * 0103 allele and DM susceptive heterodimers are related to islet beta cell function on diagnosis. The patients with DMB * 0103 allele or DM susceptive heterodimers were significantly increased in the patients with lower C-peptide level on diagnosis (56% vs. 29%; 58% vs. 34% respectively). DM heterodimes were also related to onset age and ketosis-onset-situations of the patients. The patients carrying DM susceptive heterodimers had higher probability to suffer type 1 diabetes before 10 years of age and had the predisposition to ketosis or ketoacidosis on diagnosis.
CONCLUSIONHLA- class II non-classical alleles-DMA and DMB may play an important role in pathogenesis of type 1 diabetes, and clinical status heterogeneity of type 1 diabetes may be related to genetic mechanism.

OBJECTIVETo study the linkage between -148C/T polymorphism of beta-fibrinogen gene and plasma fibrinogen levels in patients with acute cerebral infarction.
METHODSOne hundred and fifty-one patients with cerebral infarction and 101 healthy individuals were enrolled in this trial. The beta-fibrinogen gene -148C/T polymorphism was analyzed by PCR-restriction fragment length polymorphism, and plasma fibrinogen levels were obtained from prothrombin time assay.
RESULTSPlasma fibrinogen levels of patients were significantly higher than those of controls (P<0.01). In both groups, T allele carriers had higher plasma fibrinogen levels than other those did (P<0.01); and the fibrinogen level difference was still significant if both groups was based on their sex (P<0.05). Divided by age, each group of the study cases has significant difference between two genotypes (P<0.05). T -148 allele frequency of the middle age case in study group was higher than that in control group (P<0.05).
CONCLUSIONHigh plasma fibrinogen level is a risk factor to cerebral infarction. Plasma fibrinogen level is affected by -148C/T polymorphism of beta-fibrinogen gene. With or without other risk factors and environmental factors affecting, T allele increases plasma fibrinogen level and may be a heritable risk factor to cerebral infarction.
