Journal of Kunming Medical University.2013;(10):47-52.

Objective To assess prevalence and risk factors of illness within the past 2 weeks among rural residents in Menglian,under the background of essential public health service implemented generally. Methods In February 2012, the questionnaire method was employed to investigate the two-week morbidity in 2011 rural residents sampled by multistage stratified random sampling from Menglian population. Results The prevalence, that of illness within two-week among 2011 rural residents in Menglian, was 97.5‰ (95%CI 84.5‰-110.5‰) . It was lower than that of the rural region IV in China (149.6‰, <0.05) .Its age trend was the same as that of the rural region IV in China,the prevalence in 0-14 years old children,however,was higher than the counterpart in the rural region IV in China. The diseases, which two-week morbidity ranked the top five, were acute upper respiratory infection, acute gastroenteritis, hyperostosis, acute tracheobronchitis and rheumatoid arthritis. The results of multilevel logistic regression model fitted by group-level explanatory variable mountainous area, individual-level random slopes variable gender and other individual background variables indicated that there were across-level interactions between mountainous area and gender ( <0.05), the family income lower than RMB 15000 (odds ration 3.2378, 95%CI 1.9014-5.5130) and age (odds ration 1.0163, 95%CI 1.0002-1.0327) had a positive effect to two-week morbidity, and contrasting to unmarried, married had a negative effect to two-week morbidity (odds ratio 0.4727, 95%CI 0.2534-0.8819) . Conclusions Comparing with that of the rural region IV in China before implementing essential public health service, the two-week morbidity in Menglian was lower. For further elevating the health level of population, the strategies, such as intensifying material and child hygiene in the mountain area, improving sanitary conditions of low income family, and updating health consciousness in single population,would be implemented.

Journal of Kunming Medical University.2013;(9):7-12.

Objective Detect the change of relative expression level and positive rate of peripheral blood CK19 and SCCAg mRNA in early cervical cancer patients before receiving radical hysterectomy by qRT-PCR technique, then study the value of combined detection of peripheral blood CK19 and SCCAg mRNA expression in diagnosis of early cervical cancer micrometastasis. Methods Thirty patients with early (ⅠA2 ~ⅡA) cervical cancer from the department of gynecological tumors in the third affiliated hospital of Kunming Medical University were selected as experimental group, 15 patients with uterine myoma and 15 healthy volunteers as negative control group, and 15 advanced (ⅡB~ⅢB) cervical cancer patients as positive control group. Peripheral blood samples before receiving radical resection of experimental group and the same samples before treatment of control groups were collected. The changes of relative expression level and positive rate of peripheral blood CK19 and SCCAg mRNA were analyzed using qRT-PCR technique. Results There was significant difference in relative expression level of CK19 and SCCAg mRNA in the peripheral blood between experimental group and control groups ( <0.01) . And the positive rate of CK19 and SCCAg mRNA in the peripheral blood from 30 patients with early cervical cancer before operation in the experimental group was 30%(9/30) and 20% (6/30), respectively. Furthermore, combined detection of the expression of the two markers can improve the positive rate to 43.3%, much higher than single marker. There was also significant difference in the positive rate by combined detection of the two markers between the experimental group and control groups ( <0.05) . Conclusion CK19 and SCCAg mRNA could be used as the specific and suitable molecular markers for the detection of early cervical cancer micrometastasis. The combined detection of relative expression level and positive rate of peripheral blood CK19 and SCCAg mRNA by qRT-PCR array could significantly enhance the sensitivity and specificity for cancer cell detection.

Journal of Kunming Medical University.2013;(9):46-50.

Objective To study the changes of SUR1-regulated NCCa-ATP channels in core area during focal cerebral ischemia and reperfusion in rats, and to explore the therapeutic window of focal cerebral ischemia. Methods Adult male Wistar rats were rendered to undergo 120 minutes of the left middle cerebral artery occlusion (MCAO) by the intraluminal thread technique before reperfusion. The core area of the left hemisphere cortex ischemia/reperfusion at different times (reperfusion:R3 h, 6 h, 8 h, 12 h and 24 h) was taken to be tested the level of mRNA and protein expression of sulfonylurea receptor 1 (SUR1) using RT-PCR and Western-blot techniques. SUR1 of the ischemic brain microvascular endothelial cells were observed by immunofluorescence double staining at the peak expressing time point of SUR1. Results We found the up-regulation of SUR1 mRNA and SUR1 protein in ischemic infarcts tissues for R3 h, 6 h, 8 h and 12 h, peaked at R8 h, compared with the sham-operation group ( <0.05) . However, SUR1 expression increased was observed at R12 h by double immunofluorescence in microvascular endothelium. Conclusion SUR1-regulated NCCa-ATP channel may take part in cerebral ischemic damage during focal cerebral ischemia and reperfusion. The expressions of SUR1 mRNA and SUR1 protein were up-regulated in ischemic infarcts tissues. The data suggested that the best time to apply SUR1 inhibitor is within 8-12 hours after ischemia and reperfusion.

Jiankai LI ; Hui ZHAO

Journal of Kunming Medical University.2013;(9):31-37.

Objective To investigate the relationship between the expression of FAS/FASL and spermatogenesis in the contralateral testis after unilateral testicular torsion in puberty Sprague-Dawley rats. Methods Five groups of side testicular torsion adolescence SD rats model were established as follows:group A as control group, group B for testicular torsion group,group C for testicular torsion plus methylprednisolone group, D for reverse side testes excision group, and Group E testes excision plus methylprednisolone group for reverse side. SD rats were treated with testicular resection and/or injection of methylprednisolone after torsion for 24 h. The rats were executed at postoperative 1 month, and contralateral testes were collected for histopathological examination. Expression of FAS and FASL was analyzed quantitatively by immunohistochemistry with a computer pathological image analysis system. Each rat was evaluated with regard to endocrine parameters (follicle-stimulating hormone (FSH), luteinizing hormone ( LH) and testosterone ( T) by radioimmunoassay. Results Histopathological examination of the contralateral testes showed that either orchiectomy or orchiectomy plus methylprednisolone was more successful than no treatment. Fas/FasL protein in both control group and 4 experimental groups were expressed. B group showed more expression of FAS and FASL than that of the other groups. FSH, LH and T were normal in all cases. Conclusion Unilateral testicular torsion in puberty SD rats may result in higher expression of FAS and FASL, and accelerate germ cell apoptosis and subfertility. Methylprednisolone may decrease the expression of FAS and FASL and maintain spermatogenesis in the contralateral testis after the unilateral testicular torsion.

Journal of Kunming Medical University.2013;(9):13-15.

Objective To determine the situation of contraceptive use and impact factors among reproductive-age women seeking abortion in Kunming which was in the southwest of China in order to provide information for improving contraceptive use. Methods A hospital-based study was conducted among 397 women of reproductive age, seeking abortion in hospitals of different levels in Kunming from June 2011 to December 2011. They were face to face interviewed by the trained investigators with the questionnaires. Results Among 397 women, 229 cases (57.7%) had experienced induced abortion. Abortion accounted for 61.7% of married women, and unmarried accounted for 39.3%. About 36.3%never used any contraceptives, and only 21.4%of respondents used contraceptives at every intercourse. The main contraceptive before this pregnancy was condom (68.9%) . The use of contraceptives was mainly decided by couple (73.4%) . Multivariate logistic regression analysis indicated that respondents' age, educational level and access to contraceptives in hospital were associated with the use of contraceptive. Conclusion Premarital pregnancy and low rate of contraception are the main reason for induced abortion. Fewer reproductive-age women seeking abortion use contraceptives. It is necessary to increase their awareness of contraception and abortion related knowledge, provide feasible contraceptive to enable women to avoid unwilling pregnancy. Further more, it is important to promote male involvement in contraception.
