Purpose:To study the association between human papillomavirus (HPV) and cervical cancer in Uigur women from southern Xinjiang where there is a high risk of cervical cancer.Methods:HPV-C,HPV16,HPV18 and HPV6/ 11 were detected in 40 fresh tissues of cervical cancer and 40 tissues of normal cervix by using polymerase chain reaction technique.Results:The positive rate of HPV-C,HPV16,HPV18 and HPV6/11 in fresh tissue of cervix cancer were 87. 5%,72.5%,10.0% and 0,respectively;The positive rate of HPV-C,HPV16,HPV18 and HPV6/11 in normal cervix were20.0%,5.0%,0 and 7.5%,HPV16 was the most common type in HPV-C positive patients with the rate of 82.8 %. The positive rate of HPV-C and HPV16 in cervical cancer were significantly higher than that in control groups;The positive rate of HPV16 in squamous cancer of cervix was significantly higher than that in adenocarcinomas of cervix;while the posi- tive rate of HPV 18 in adenocarcinomas of cervix was significantly higher than that in squamous cancer of cervix(P0.05).Conclusions:HPV16 infection plays an important role in the carcinogenesis of cervical cancer of Uigur women from Southern Xinjiang,HPV16 infection is closely correlated with squamous carcinomas of cervix,while HPV18 infection is closely correlated with adenocarcinomas of cervix.The positive rate of HPV-C and HPV16 have no correlation with clinical stages and histological grade of cervical carcinomas.

Aim To study the activity and mechanism of inhibition of myocardial hypertrophy of total fla-vonoids of Cydonia oblonga Mill. in spontaneously hy-pertensive rats ( SHR) . Methods Total flavonoids of COM ( COMF) were separated and purified by the op-timal process. SHR were divided into 6 groups: SHR control group ( SHR) , captopril group ( SHR+CAP, 25 μg·g-1 ) , Eucommia ulmoides Oliver group ( SHR+EUO, 30 μg·g-1 ) , low ( SHR+COMF-L, 40 μg ·g-1 ) , middle ( SHR+COMF-M, 80 μg·g-1 ) and high dose ( SHR+COMF-H, 160 μg·g-1 ) of COMF groups. Wistar-Kyoto (WKY) rats (n=8) were given distilled water as control. The drugs were given by in-tragastric administration for 16 weeks. The histological and pathological examinations of the heart were per-formed and organic damage was valued. The levels of AngⅡand ALD in blood and heart were evaluated. The mRNA and protein expression of ACE, ACE2 and AT1 was determined by RT-PCR and Western blot to e-valuate the effect of COMF on RAAS. Results Com-pared with SHR control group, HW, HW/BW, LVM and LVM/BW decreased in SHR+COMF-M and SHR+COMF-H groups. Cadiomyocyte hypertrophy was in-hibited in COMF groups. The concentration of AngⅡand ALD in heart and blood decreased. ACE and AT1 mRNA and protein expression in heart tissue de-creased, while ACE2 mRNA expression increased ( P<0. 01 or P <0. 05 ) , Conclusion Total flavonoids of Cydonia oblonga Mill. show the effect of inhibition of myocardial hypertrophy in spontaneously hyperten-sive rats and the mechanism is related to inhibiting ac-tivity of renin-angiotensin-aldosterone system.

Objective To study the distribution of human papilloma virus(HPV)subtypes in Uyghur people from the high risk region of cervical cancer in Xinjiang. Methods 21 subtypes of HPV from 400 cases of men's swabs of penile and 400 cases of women's cervix swabs were detected, using flow-through hybridization and gene chip technology. Results(1)The positive rate of HPV among the 400 women cases was 14.25% ,with HPV16 the most common type. In women whose HPV was positive, the positive rate of HPV16 was 66.67%. The ranking of frequencies on the HPV subtypes in women were: HPV 16, 58,39, 18,33,52,43,66, CP8304, HPV6 and 11.(2)Among the 400 male cases, the positive rate of HPV was 8.00%, with HPV16 the most common type. In men whose HPV was positive, the rate of HPV16 was 44.44%. The ranking of HPV subtypes in men were HPV16, 43, 33, 39, 6(HPV39 and 6 are equivalent)and 53.(3)Both wives and husbands were infected by different subtypes of HPV, the positive rate was relatively low among men whose wife's HPV were positive. However, the HPV positive rate was relatively low among women whose husband's HPV were positive. The concordance infection rate of women and men were 7.02% and the concordance infection rate of men and women were 9.38%. Conclusion The HPV positive rates were relatively low in both men and women living in the region with high risk of cervical cancer in Xinjiang. However, the positive rate of high risk types HPV and HPVI6 in both men and women were relatively high. Uyghur men seemed to have played a certain role related to the carcinogenensis of cervical cancer. HPV16 was the main type in both men and women in Xinjiang.
