To evaluate the application of intracavitary three-dimensional ultrasonography in the diagnosis of polycystic ovary syndrome ( PCOS). The three-dimensional volumes of ovary were measured by intracavitary ultrasonography in 40 PCOS patients and 40 normal controls. The diagnostic value of parameters derived from three-dimensional ultrasonography was evaluated by using the receiver operating characteristic (ROC) curve. The ovarian volume, stromal volume, and the stromal/total volume ratio in PCOS group were significantly higher than those in control group (both P ＜ 0. 05 ) ; the area under ROC curve ( AUC ) of them were 0. 876, 0. 926, 0. 886 respectively. Among these parameters, stromal volume had the highest diagnostic value for PCOS, the cut-off value of which was 7.52 cm3 with a sensitivity of 88% and a specificity of 90%. Volume parameters of ovary measured by intracavitary three-dimensional ultrasonography can offer quantitative information for the diagnosis of PCOS.

Objective To investigate the serum levels of IL-10 and TGF-β1 and their significance for patients with sys-temic lupus erythematosus( SLE) .Methods A total of 135 cases were available for the study including 63 cases in primary group(A), 40 cases in remission group(B) and 32 cases in healthy control group(C).ELISA method was used to deter-mine the concentrations of IL-10 and TGF-β1 in serum.Finally, the results of group A were analyzed on the basis of System-ic Lupus Erythematosus Disease Activity Index( SLEDAI) .Results The level of IL-10 in serum of group A was significant-ly higher than that of group B and group C.The level of IL-10 in serum of group B was significantly higher than that of group C(P<0.05).The level of IL-10 in group A had active correlation with SLEDAI.The level of TGF-β1 in serum of group A was significantly lower than that of group B and group C.There was no statistical difference between group B and group C(P>0.05).The level of TGF-β1 in serum of group A had negative correlation with SLEDAI.The cases in group A were divided into three subgroups by SLEDAI:21 cases in mild activities subgroup, 30 cases in moderate activities sub-group,and 12 cases in severe activities subgroup, the levels of IL-10 and TGF-β1 in the three subgroups were significantly different(P<0.05).Conclusions IL-10 and TGF-β1 are involved in activity and severity of SLE.

The expression of specific genes in sex chromosomes is the basis of sex-specific membrane protein in mammalian spermatozoa. The gene expression products are shared among spermatozoa through intercellular bridges, however, the phenomena of male transmission-ratio distortion and sex ratio distortion proved that differential proteins exist between X and Y spermatozoa. In addition, the existence of sex-specific proteins was confirmed by the separation experiment of X/Y chromosome bearing spermatozoa and the detection result of sex specific proteins. At the same time, it was also confirmed that the difference of the sex-specific protein is weak . The advance of separation techniques as well as the integration and optimization among these techniques has made it possible to separate sex-specific membrane proteins in mammalian spermatozoa.

Objective To investigate the association of nitrotyrosine with coronary heart disease (CHD) in type 2 diabetes mellitus.Methods The nitrotyrosine levels were determined in 109 patients of type 2 diabetes mellitus without CHD (T2DM).One hundred and fifty-two patients of type 2 diabetes mellitus with CHD (T2DM-CHD) and 103 healthy control subjects by ELISA.Results T2DM-CHD patients had significantly increased nitrotyrosine compared with T2DM group and the control group [ ( 78.17±10.68 )nmol/L,(70.50 ± 9.13) nmol/L vs ( 63.23 ± 11.55 ) nmol/L,Ps ＜ 0.01 ].Nitrotyrosine was correlated with total cholesterol,triglyceride,fasting glucose and Gensini Score (r=0.361,P=0.009;r =0.206,P=0.001 ;r=0.347,P=0.026; r=0.466,P ＜ 0.001 ).Multivariable logistic regression showed nitrotyrosine was independently associated with CHD combined with type 2 diabetes mellitus ( OR=1.094,95％ CI:1.053-1.137 ; P ＜ 0.01 ).Conclusion Nitrotyrosine plays an important role in the formation and development of cardiovascular disease in tvoe 2 diabetes.

Objective To investigate the change of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the skin of diabetic rats, and to explore the potential role of MMP-9/TIMP-1. Methods Diabetic rats were induced with streptozotocin (STZ). Then all rats were maintained for 6 weeks. Routine pathological examination and immnnohistochemistry were made to reveal the histological and cytological appearances. RT-PCR and Western blotting were used to detect the expression of mRNA and protein of MMP-9 and TIMP-1 in the skin. Results Six weeks after STZ treatment, examination of HE-stained skin sections from normal and diabetic animals revealed that the epidermis and dermis layers were thinner in diabetic rats than those in control rats. The skin of diabetic rats showed features of atrophy such as disorganization of connective tissue fiber bundles and enlarged space between collagen fiber bundles. In contrast, thick bundles of connective tissue were observed in the dermis of normal rat skin. In normal skin, cells had a bipolar, spindle-shaped appearance in the thick collagen bundles, while in the skin of diabetic animals the interstitial cells had a rounded, shrunken and crenated appearance. The relative values of expression of MMP-9 in diabetic group were higher than those in normal group with significant difference, however, the relative values of expression of TIMP-I in diabetic group were lower than those in control group. Conclusion The changes in cutaneous histology and cytology appear earlier than skin wound. These "underlying disorders" may be associated with the imbalance of MMP-9/TIMP-1.
