Objective To investigate the relationship between single nucleotide polymorphism (SNP) of susceptibility genes CD-KAL1 ,CDKN2A-CDKN2B ,TCF7L2 and HHEX-IDE of type 2 diabetes mellitus and gestational diabetes mellitus (GDM) in Jiangsu region .Methods 185 healthy pregnant women without GDM tendency (control group) and 176 pregnant women with GDM (GDM group) were enrolled .Case-control method and Multiplex SNaPshot SNP genotyping technology were utilized to detect genotypes at SNP loci of CDKAL1 ,CDKN2A-CDKN2B ,TCF7L2 and HHEX-IDE of pregnant women both in the two groups , and all SNP loci were subject to continuous disequilibrium analysis .Results Compared the allele frequencies of pregnant women in GDM group and the control group ,C allele of CDKAL1(rs7754840) was a risk factor for GDM .The risk of suffering GDM of CC genotype carriers was 1 .73 times the non-CC genotype carriers[P<0 .01 ,OR=1 .73 ,95% CI:1 .28-2 .33] .No statistical difference wasfound in gene distribution of detection loci of CDKN2A-CDKN2B(rs10811661),TCF7L2(rs7903146) and HHEX-IDE (rs1111875) .The genotype frequencies of CDKAL1(rs7754840) ,CDKN2A-CDKN2B(rs10811661) ,TCF7L2(rs7903146) and H HEX-IDE(rs1111875) were all accordance with the law of genetic equilibrium .Conclusion CDKAL1(rs7754840) is closely re-lated to GDM susceptibility in Jiangsu region .

Objective To establish the questionnaires of sexual knowledge demands ,that was used for providing a tool to as‐sess the knowledge of college students and carry out targeted education .Methods The initial theoretical frame and items of ques‐tionnaires of sexual knowledge demands were generated from literature review and open questionnaire survey ;127 students were in‐tended the pretest and 901 students were intended the formal test .Then ,item analysis ,exploratory and confirmatory factor analyses were conducted to assess its reliability and validity .Results The items of questionnaires of sexual knowledge demands was consis‐ted of 29 items belonging to five factors which were sexual behavior ,moral of sex ,the psychology of interrelation between males and females ,sexual physiology of males and sexual physiology of females .The cronbachαcoefficient of the scale was 0 .904 ,confirmato‐ry factor analysis showed the fit indexes reached the standard of good fitting indicators(χ2/df = 6 .10 ,CFI= 0 .92 ,NFI= 0 .91 , NNFI=0 .91 ,RMSEA=0 .09) .Conclusion The questionnaires of demands of sexual knowledge has good reliability and validity , and can be used for related research .

OBJECTIVE: To obtain the microcrystal agents of sorafenib and examine the in vivo anti-tumor efficiency of sorafenib-microcrystal on hepatocellular carcinoma cells. METHODS: The solubilizing solution or microcrystal of sorafenib was obtained. A highly aggressive HCC cell line, MHCC97-H, was used to form the subcutaneous or intra-hepatic tumor model in nude mice. Sorafenib-solution or microcrystal was injected into tumors. The clearance curve or anti-tumor efficiency of solubilizing solution or microcrystal was identified. Endogenous of EMT related indicators was identified by qPCR. RESULTS: Sorafenib slowly released in tumor tissues by sorafenib-microcrystal but not sorafenib-solution. Treatment of sorafenib-microcrystal inhibited the in vivo growth of MHCC97-H cells. CONCLUSION: The microcrystal agents of sorafenib is prepared. This work also establishes the in vivo anti-tumor efficiency of sorafenib-microcrystal on HCC cells.

Objective:To investigate the clinicopathological features and differential diagnosis of 2 patients with renal epithelioid angiomyolipoma (AML), representing 5.4 % of a series of 37 patients undergoing biopsy for renal tumors. Methods:The histopathological, immunohistochemical and clinical characteristics of renal epithelioid angiomyolipoma were studied by immunohistochemical stain for melanoma marker (HMB45), (Pan)melanoma marker Ab-1,cytokeratin (CK), smooth muscle actin (SMA), epithelial membrane antigen (EMA),vimentin (Vim), p53, proliferating cell nuclear antigen(PCNA), Ki67 antigen. Results:Two patients,aged 31 and 39,were alive for 8 and 10 months,respectively.Microscopically, both tumors were mainly made up of diffuse sheets of epithelioid cells and scattered thick-walled blood vessels, necrosis was account for up to 30% of the mass. The epithelioid cells had huge, extremely pleomorphic nuclei with abundant eosinophilic cytoplasm. Scattered tumor giant cells with prominent nuclei were also seen. The epithelioid AML regions of these tumors were immunoreactive for HMB45, (Pan)melanoma marker Ab-1, SMA, Vim and PCNA. Neither atypical epithelioid cells nor typical AML cells were immunoreactive for cytokeratin (CK) and epithelial membrane antigen (EMA).Conclusion: The results of this study suggested that the renal epithelioid AML was a mild malignant tumor before distant metastases. The differential diagnosis between renal malignant AML and sarcomatoid renal cell carcinoma was established by immunohistochemical findings.

Objective To establish the linear regression equation between body height and com bined length of manubrium and mesosternum of sternum m easured by CTvolum e rendering technique (CT-VRT) in southw est H an population. Methods One hundred and sixty subjects, including 80 m ales and 80 fem ales w ere selected from southw est H an population for routine CT-VRT(reconstruction thickness 1 m m ) ex-am ination. The lengths of both manubrium and mesosternum w ere recorded, and the com bined length of manubrium and mesosternum was equal to the algebraic sum of them . The sex-specific linear regression equations between the com bined length of manubrium and mesosternum and the real body height of each subject w ere deduced. Results The sex-specific sim ple linear regression equations between the com bined length of manubrium and mesosternum (x3) and body height (y) w ere established (m ale:y=135.000+2.118x3 and fem ale:y=120.790+2.808x3).Both equations show ed statisticalsignificance (P<0.05) w ith a 100% predictive accuracy. Conclusion CT-VRTis an effective m ethod for m easurem ent of the index of sternum . The com bined length of manubrium and mesosternum from CT-VRTcan be used for body height estim ation in southw est H an population.
