OBJECTIVE:To provide reference for improving the utilization ratio of emergency contraceptive(EC)pills and re-ducing unwanted pregnancy. METHODS:Among 458 women with unwanted pregnancy in our hospital,self-designed question-naires were used to survey the respondents'knowledge and utilization of EC pills,reasons for not using,sources of EC knowledge and drug availability. The results were analyzed statistically. RESULTS:Totally 458 questionnaires were distributed and then 426 valid questionnaires were collected with effective rate of 93.0%. Among respondents,the awareness rate of EC was 81.2%(346/426),and the rate of those receiving higher education was higher than that of other education levels(P<0.001). 56.3%(240/426) of the respondents had ever used EC pills at one time,the utilization ratio of EC pills were higher in women less than 30-year-old and receiving higher education than other age and educational levels(P<0.01). Only 20.2%(86/426)of the respondents ever used EC pills after the last menstrual period and only 3.5%(3/86) of them took EC pills correctly. Not understanding or knowing EC was the main reason for not using EC pills,accounting for 60.6%(206/340). The highest proportion of source which the respon-dents got EC knowledge was network,accounting for 53.5%(185/346). 37.0%(81/219) of the respondents who had ever pur-chased drugs couldn't purchase EC pills conveniently. CONCLUSIONS:The utilization ratio of EC pills in women with unwanted pregnancy needs to be improved and non-standard drug use is more common. It indicates that health education of contraception still need to be strengthened and the availability of EC pills improved.

IL-18 was discovered as a proinflammatoty cytokine,stimulates natural killer and T cells and enhances Th1/Th2 immune response, and plays a central role in inflammation and immune response.. Immune-stimulating effects of IL-18 as a adjuvent agent against cancer,have antineoplastic properi-ties. However, Higher expression or secretion level of IL- 18 is detected in the blood of the majority of cancer pa-tients with poor prongnosis. IL-18 has also been associated with cancer progression and immune escape,is able to induce angiogenesis, metastasis. The dual effects of IL-18 in cancer need to be investigated further.

Neonatal sepsis progresses very fast,and its clinical signs are non-specific,and it can cause severe complications,such as shock,MODS.Therefore,early diagnosis is key to reduce mortality and improve prognosis.The clinical indicators in diagnosis of neonatal sepsis includ bacterial culture,peripheral hemogram,acute phase reaction proteins,cytokines,cell surface antigen and bacterial gene detection.This article reviews the clinical significance of these indicators in the early diagnosis,condition assessment,treatment monitoring of neonatal sepsis.

Objective To optimize the expression conditions(expression and induction conditions)and purification methods(non-denaturing and denaturing purification)of recombinant Hq001 protein in salivary glands of Haemaphysalis qinghaiensis.Methods The recombinant plasmid pET-30a-Hq001 was transformed into competent cells E.coil BL21(DE3),E.coil Rosetta(DE3)and E.coil ArcticExpress(DE3)pRARE2 respectively for the selection of an optimal expression strain.The final concentration of IPTG(0,0.5,1.0 mmol/L),induction temperature(20,25 ℃)and induction time(0,2,4,6,8 h)were optimized.The recombinant bacteria expressed under the ideal induction condition were homogenized by French press and the target protein was purified by passing through a Ni-NTA affinity chromatography column under either native(denaturationrenaturation-column chromatography)or denatured conditions(denaturation-column chromatography-renaturation).The purified products were analyzed by 12% SDS-PAGE.Results E.coil BL21(DE3)was proved to be the most suitable strain for the expression of recombinant Hq001 protein.The optimum induction condition was induction with 0.5 mmol/L IPTG for 4 h at 25 ℃.The target protein with a relative molecular mass of approximately 18 800 was obtained by non-denaturing purification method,and the size was consistent with the expectation.Conclusion The recombinant protein rHq001 in salivary glands of Haemaphysalis qinghaiensis can be obtained by the optimized expression conditions and purification methods.

MicroRNA (miRNA) is an important gene regulatory molecule involved in the occurrence of a variety of diseases and is relat-ed to tumors. MicroRNA has become a new direction of oncology research in recent years. Studies showed that miR-29 plays dual roles, as tumor suppressor and tumor promoter. The expression of miR-29 significantly differs between cancer and normal tissues. miR-29 is predicted to be a biomarker for early diagnosis and prognosis prediction of certain cancer. This paper reviews the role of miR-29 in the pathogenesis of cancer.

Objective To investigate the changes of plasma miR-29a level in patients with hepatocellular carcinoma(HCC) and its clinical significance.Methods Case-control study,30 patients with HCC,30 patients with cirrhosis of liver (LC) and 30 healthy controls (HC) were recruited from Shiyan Taihe Hospital,2016 January to June.The level of microRNA-29a (miR-29a) in plasma was detected by real time quantitative PCR,and the sensitivity and specificity of plasma miR-29a expression in the diagnosis of HCC were analyzed by receiver operating characteristic curve (ROC),and to analyze the correlation between the miR-29a and the alpha-fetoprotein (AFP) in patients with hepatocellular carcinoma,the combination of miR-29a and AFP could improve the diagnostic efficiency of HCC.Results The relative expression of miR-29a was significantly different between HCC group (3.38±8.37),LC group (8.79±3.80) and HC group (11.98±6.64),the expression level of miR-29a in HCC group was significantly lower than that in LC group (P=0.046) and HC group (P=0.001),and that in LC group was significantly lower than that in HC group (P=0.026).The area under the ROC curve of miR-29a was 0.816 (95％ CI 0.695 to 0.938) less than AFP 0.918 (95％ CI 0.853 to 0.982),and the diagnostic efficiency of miR-29a was not as good as that of AFP.The levels of miR-29a and AFP in plasma of patients with hepatocellular carcinoma were significantly correlated (P=0.002).Conclusion The level of miR 29a in plasma of patients with HCC decreased,which may become the reference index of HCC diagnosis.
