ABSTRACT
Objective@#To explore the effects of high-fat diet exposure on glucolipid metabolism and ovarian function in offspring of female Sprague Dawley rats.@*Methods@#Female and male rats were mated in cages at a ratio of 2∶1. Pregnant mice were collected and randomly divided into normal feed group (control group) and high-fat and high-glucose feed group (observation group). Female offspring were selected as the research object. After the offspring entering the stage of sexual maturity, the blood was taken from abdominal aorta artery. The contents of serum related factors were determined by automatic biochemical analyzer and enzyme linked immunosorbent assay (ELISA) kit. Hematoxylin-eosin staining (HE) was used to directly observe the distribution and quantity of liver tissue and the quantity and structure of ovarian follicles.@*Results@#Compared with the normal control group, the body weight, blood glucose, blood lipids and fat coefficient in high-fat diet rats were significantly increased (P<0.05). The secretions of estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH) in the ovary were significantly reduced (P<0.05). HE slices showed that compared with the normal control group, there were fat vacuoles in the cytoplasm of hepatocytes, the increase of hepatocyte arrangement gap, the number of adipocytes and the diameter of fat droplets in the observation group. The quantities of primordial follicles and primary follicles in the ovary showed increasing trend in high-fat diet group, and the diameter of follicles was decreased.@*Conclusions@#High-fat and high glucose diet may cause abnormal glucolipid metabolism. It is speculated that high fat diet may cause ovary to be surrounded by fat through fat accumulation in the abdomen and buttocks of female offspring, which directly leads to dysfunction.

ABSTRACT
ObjectiveTo investigate the distribution of types of human papillomavirus(HPV)in cervical cancer Xinjiang Uyghur women.MethodsFrom june 2008 to April 2010,patients in the gynecological departmen of people's Hospital of Xinjiang Uygur Autonomous Region,who was gidiagnosed cervical cancer and came from southern of Xinjiang.Cervical cells of these patients were collected,HPV genotyping DNA chip was used to detect HP-DNA of each collected sample.ResultsTotally 120 wommen were screened,the infecton rationof HPV was 95.8%(115/120).The positive rate of HPV-16 infection was 69.6%(80/115);other highrisk HPV infection rates were ranked from high to low as HPV-56,HPV-33,HPV-18,HPV-45,HPV-58,HPV-51,HPV-59,HPV-31,HPV-52,HPV-39,HPV-68,HPV-73,low-risk HPV infection rates were ranked from high to low as HPV-11,HPV-42,HPV-43,HPV-6.However,HPV-35,HPV-53,HPV-66,HPV83,HPV-MM4 and HPV-44 were not detected.Single infection of HPV16 or HPV56 was 53.9%(62/115)and 17.4(20/115)respectively,ultiple infection rate was 29.6%(34/115).ConclusionHPV-16 is the most common types in cervical cancer of Xinjiang Uyghur women.HPV56 maybe susceptible to the Xinjiang Uyghur women,reflecting the specificity of HPV infection in cervical cancer of Xinjiang Uygur women.It needs deep study to development a suitable HPV vaccines.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the relationship between human papillomavirus (HPV) 16 infection and the expression of p33(ING1b), human telomerase reverse transcriptase (hTERT) in cervical squamous cell carcinoma of Uygur Female in Xinjiang Uygur Autonomous Region.</p><p><b>METHODS</b>Polymerase chain reaction (PCR) and immunohistochemical methods were used to detect HPV16 infection and the expression of p33(ING1b) and hTERT in the normal control group (n=12), the patients with cervical intraepithelial neoplasm (CIN) (n=34), and the patients with cervical squamous cell carcinoma (SCC) (n=50).</p><p><b>RESULTS</b>In the cervical tissues of Uygur female, the HPV16 infection rate was 0 in control group, 22.2% in the CIN 1 group, 44.0% in CIN 2 & CIN 3 group, and 74.0% in SCC group (P = 0.000). The expression rate of p33(ING1b) decreased was 91.7% in control group, 77.7% in CIN 1 group, 68.0% in CIN 2 & CIN 3 group, and 36.0% in SCC group (P = 0. 000). The expression rate of hTERT was 50.0% in control group, 66.6% in CIN 1 group, 88.0% in CIN 2 & CIN 3 group, and 94.0% in SCC group (P = 0.000). In the cervical tissues of Uygur female, the HPV16 infection rate was negatively correlated with the expression of p33(ING1b) (r = -0.294, P = 0.004), and was positively correlated with the expression of hTERT (r = 0.286, P = 0.005). The expression of p33(ING1b) was negatively correlated with the expression of hTERT (r = -0.361, P = 0.000).</p><p><b>CONCLUSION</b>The infection of HPV 16 correlates with the decreased expression of p33(ING1b) and increased expression of hTERT in the cervical squamous cell carcinoma of Uygur female in Xinjiang.</p>
