Objective To investigate the relationship between the polymorphism of site rs228648 in urotensin Ⅱ gene and the genetic susceptibility to gestational diabetes mellitus in northern Chinese women. Methods Genotyping was conducted to investigate the polymorphism of site rs228648 (G—A) in urotensin Ⅱgene among 70 unrelated gestational diabetes mellitus(GDM) subjects and 70 normal controls. DNA samples isolated from leucocyte of the control and study groups were analyzed for single-nucleotide polymorphisms of the urotensin Ⅱ gene at positions rs228648 using polymerase chain reaction and restriction analysis. Results (1)The distribution of genotype frequencies of site rs228648 accorded with Hardy-Weinberg′s equation law, being colony representative.(2)The frequency of G allele of site rs228648 was 70.7% in GDM group, significantly higher than that in the control group (57.9%, P0.05). (3) Women in control group were more likely to be homozygous for the allele A of site rs228648 than women with GDM. The frequency of A/A genotype of rs228648 was negatively correlated with GDM group. By the logistic procedure, after adjustment by age and gestational weeks, the odds ratio was 0.312 , and Wald Confidence Limites were 0.108 to 0.900 (P= 0.031). Conclusion Urotensin Ⅱ gene may contribute to the genetic susceptibility to gestational diabetes mellitus in northern Chinese population. G allele of site rs228648 is related to GDM possibly, and that homozygosis A of site rs228648 is likely to be an important protecting factor for GDM.

Objective To understand the effect of Kuntai Capsule on mice endometrial receptivity by comparing the lyso‐phospholipids acid receptor‐3(LPAR3) expression in endometrium during mouse embryos implantation period .Methods Ninety 6-8 week old Kunming female mice were randomly divided to three groups :the group A [controlled ovarian hyperstimulation (COH)] ,B (COH+Kuntai Capsule) and C(normal saline control) ,30 cases in each group .The vaginal plug was performed on the next day after mating .Five mice in each group were daily killed on 1 -6 d .The serum estradiol(E2) and progesterone(P) levels were detected .The glands number and the immunohistochemical integrated optical density (IOD) were also determined .Results The levels of serum E2 amd P in the group A and B were higher than those in the group C at the same period (P<0 .05);in the HE staining ,the glands number in the group A was significantly decreased compared with the group B and C (P<0 .05) .The IOD value of LPAR3 on 3 d in the group A was significantly lower than that in the group B and C (P<0 .05) ,while the group B was slightly higher than the group C without statistical difference (P>0 .05) .Conclusion Kuntai Capsule may play the role for improving the endometrial receptivity by improving the normal space‐time expression of LPAR3 .

Objective To explore the expressions and clinical significances of deleted in liver cancer-1 (DLC-1 ) and Rho associated coiledcoil forming protein kinase (ROCK )Ⅰ in non-small lung cancer (NSCLC).Methods The expressions of DLC-1 and ROCKⅠ in NSCLC and adjacent tissue of 48 patients with pathologically confirmed as NSCLC and undergone surgical resection were detected by immunohistochemis-try EnVision method.The correlations among DLC-1 protein,ROCKⅠ protein and the clinical pathological characteristics were analyzed.The prognostic value of DLC-1 in patients with NSCLC was studied.Results The expression of DLC-1 protein in NSCLC tissue was low or missing,and the positive rate was 33.3%(16/48),significantly lower than that in the tissue adjacent to carcinoma 70.8% (34/48),with statistical significance (χ2 =13.523,P<0.01).The positive expression rate of ROCKⅠprotein in NSCLC was 58.3%(28/48),higher than that of tissue adjacent to carcinoma 0(0/48),with statistical significance (χ2 =39.529, P<0.01).The expression of DLC-1 protein was correlated with tumor differentiation,lymph node metastasis and clinical stage,rather than with sex,smoking history and organization type.Through the correlation analy-sis,the expression of ROCKⅠin DLC-1 positive group was 37.5%(6/16),and the expression rate of ROCKⅠ in DLC-1 negative group was 68.8%(22/32).There was negative correlation between DLC-1 and ROCKⅠin NSCLC tissues (r=-2.214,P=0.039).The 3 year survival rate in DLC-1 protein high expression group was obviously higher than that in low expression group,with statistical significance (P=0.043).Conclusion Low or missing expression of DLC-1 and high expression of ROCKⅠ protein may play an important role in the occurrence and development of NSCLC.Detecting the expression of DLC-1 and ROCKⅠprotein may be useful for evaluating the biological behavior and prognosis of NSCLC.

Objective To explore the CD38 expression in T-cens(CD38-T)of chronic lymphocytic leukemia(CLL).Methods Multi-parameter flow cytometry was used to detect the expression of CD38,ZAP-70 and CD4/CD8 in 83 CLL patients.Results CD38 was positively expressed in 49.4%(41/83)T-cells(CD38-T)and 50.6%(42/83)tumor cells(CD38-B)of all CLL patients.The expression of the CD38-T was highly correlated with CD38-B(r=0.553,P＜0.01).ZAP-70+CD38+-T and ZAP-70-CD38-T constituted 67.5%(56/83)of CLL patients.There was significant correlation between CD38-T and ZAP-70 (r=0.349,P＜0.01).There was 33.3%(14/42)patients with CD38-T in Binet A patients,and 65.9% (27/41)in Binet B+C patients.There was also significant correlation between CD38-T and Binet B+C(r=0.312,P＜0.05),and CD4/CD8(r=0.453,P＜0.05).Conclusions Aberrant expression of CD38 in T-cells might be of prognostic relevance in CLL Most of the patients with high level CD38-T expression are accompanied with disorder or imbalance of immune function.CD38 expression in T cells might be a new prognostic factor in CLL.

Objective:To compare the results of two different measures assessing prospective memory (PM) in elderly schizophrenia,and explore their diagnostic validity.Methods:Fifty patients who were diagnosed as schiz-ophrenia according to the criteria of Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-Ⅳ)and 50 normal elderly people were enrolled in the study.Laboratory paradigm prospective memory task and the Chinese version of the Cambridge prospective memory Test (C-CAMPROMPT)were administered to measure thelevel of EBPM and TBPM.The Wechsler Adult Intelligence Scale-Fourth Edition,Continuous Performance Test-I-dentical Pairs were used to evaluate IQ and attention.Results:Whether in the laboratory paradigm or C-CAM-PROMPT,schizophrenia group performed worse than normal controls on PM total scores[7(0,16)vs.12(0,16),14 (4,34)vs.25(11,36)],EBPM[3(0,8)vs.6(0,8),7(2,16)vs.14(4,18)]and TBPM [3(0,8)vs.6(0,8),6(2,18) vs.12(4,18)],and patients had comparable performances in PM subtypes[-1.0(-2.2,1.0)vs. -1.0(-2.1, 0.8),-1.9(-3.4,0.8)vs. -1.8(-2.9,1.6)].In the C-CAMPROMPT,the scores of EBPM and TBPM were negatively related to age(r=-0.36 --0.40,P<0.001 ),but there was no significant relationship between PM performance and age in the laboratory paradigm task.The area under ROC curve of the laboratory paradigm and C-CAMPROMPT were 0.73 and 0.85.While 8 and 19 as the cut off value,the sensitivity were 0.60 and 0.74,and the specificity were 0.76 and 0.90,respectively.Conclusion:The two measures have confirmed that the elderly schizophrenia have comparable performances in EBPM and TBPM.Both the C-CAMPROMPT and the laboratory paradigm have moderate level of diagnostic validity,but the former is slightly higher and more susceptible to aging.
