Objective To estimate the clinical value of 4 methods of endometrium preparation for frozen‐thawed embryo transfer(FET ) cycle .Methods Total 320 FET cycles completed in center of reproductive medicine of Qingyuan people′s hospital from March 2013 to March 2015 were retrospectively analyzed ,and divided into 4 groups :natural cycle group(group A ,n=70) ,o‐vulation‐inducing cycle group(group B ,n=152) ,hormone replacement treatment(HRT) cycle group (group C ,n=74) ,down‐regu‐lated HRT cycle (group D ,n=24) .The pregnancy outcomes were followed and compared among these different 4 groups .Results In FET cycles ,the clinical pregnancy rates and implantation rates of group B ,group C and group D were significantly higher than that of group A (P<0 .05) ,there were no significant differences in the rates of multiple pregnancy ,biochemical pregnancy ,early a‐bortion and ectopic pregnancy among 4 groups(P>0 .05) .However ,the rank of the FET cycle of group D was significantly higher than those of the other three groups(P<0 .05) .Conclusion In FET cycles ,the methods of ovulation‐inducing ,HRT and down‐reg‐ulated HRT all have favorable clinical outcomes ,and the method of down‐regulated HRT is more suitable for patients with previous implantation failure .

To investigate the regulation of osteoclast inhibitory lectin (OCIL) mRNA expression by prostaglandin E2 ( PGE2 ) in rat osteoblastic cells and the involved signaling pathways. Rat primary osteoblasts and UMR106 osteoblast-like cells were cultured and treated with various doses of PGE2 or regulators of different signaling pathways for different periods of time, the cells were then harvested at indicated dates. Total RNA were isolated and OCIL mRNA expression were studied by real-time PCR. PGE2, Forskolin, db-cAMP, and A23187 increased OCIL mRNA by 2. 38 fold,4. 2 fold,4. 5 fold, and 5. 1 fold ( all P＜0. 01 ) respectively, while PMA downregulated OCIL mRNA expression by 50% ( P＜0. 01 ). KT-5720, verapamil, W7, and PD98059 downregulated PGE2 induced OCIL mRNA expression by 56%, 40%, 65%, and 60%, respectively( all P＜0. 0l ). While chelerythrine enhanced PGE2 induced OCIL mRNA expression by 30% ( P＜0. 05 ). PGE2 up-regulated the expression of OCIL in rat osteoblastic cells via PKA, MAPK, and Ca2+/Calmodulin signaling pathways.

Objective To evaluate the clinical efficacy of super-selective prostatic arterial embolization(PAE) for the treatment of benign prostatic hyperplasia(BPH).Methods From February 2012to March 2015,a total of 17 patients with BPH who failed in medical treatment,or unwilling to accept surgery were selected for PAE as the study group.The mean age was 73 years (range 61-84 years) and the mean prostatic volume was 64.6 ml (ranging 50-85 ml).The study group underwent super selective arterial embolization.The internal iliac artery angiography was performed and the main blood vessel of prostate was showed.The femoral artery was punctured under local anesthesia and X-ray monitoring,a F4-5 Cobra catheter was inserted,and then the Embosphere microspheres were implanted.A total of 40 patients who underwent transurethral resection of the prostate(TURP) were selected as the control group.The mean age was 70 years (ranging 59-87 years).The mean prostatic volume was 68.7 ml(ranging 55-90 ml).All cases were followed up for 1 year.The changes of prostatic volume (PV),international prostate symptom score(IPSS),quality of life (QOL),pre-and post-treatment peak urinary flow (Qmax) were evaluated.Results For the 17 patients who underwent PAE,the PV decreased from (64.6 ± 10.2) ml to(42.0 ± 7.5) ml,the IPSS decreased from 23.9 ±4.9 to 13.1 ±3.5,QOL decreased from 4.1 ±0.7 to 2.1 ±0.7,and Q increased from (9.5 ± 3.7) ml/s to(21.8 ± 4.2) ml/s,which were statistically significant (P ＜ 0.05) compared with the pre-treatment parameters.The post-operative parameters of the control group were also significantly improved compared with the preoperative parameters (P ＜ 0.05).Conclusions PAE is safe and effective in treating BPH,especially for those failing in medical treatment,or unwilling to accept surgery.

Objective:Immune cells and inflammatory mediators play important roles in the development of atherosclerotic vascular inflammation.This study focuses on the direct effect ofIL-27 on human coronary artery endothelial cells.Methods:In this study,the effects of IL-27 and TNF-α on inflammatory cytokines and chemokines were investigated.Results:IL-27 could significantly enhance the TNF-α-mediated upregulation of inflammatory cytokine IL-6 and chemokines CCL5 from human coronary artery endothelial cells.The release of IL-6 and CCL5 was significantly suppressed by specific signaling molecule inhibitors.Conclusion:The induction of these mediators from the human coronary artery endothelial cells could be differentially regulated by the c-Jun N-terminal kinase,p38 mitogen-activated protein kinase,and nuclear factor-κB pathways.These results provided new insights into the effect of IL-27 on the TNF-α mediated activation of human coronary artery endothelial cells in atherosclerotic vascular inflammation.

OBJECTIVE To investigate the distribution and drug resistance status to pathogens from urinary tract and offer scientific evidence for reasonable usage of antibiotics.METHODS Totally 389 isolates derived from infected urinary tract in mountain area of western Hubei Province from 2002 to 2005 were identified and antibiotic susceptibility test was performed.RESULTS Escherichia coli accounted for 66.1% ranking the first.The isolates were all susceptible to imipenem and vancomycin.The ratio of ESBLs in E.coli and Klebsiella pneumoniae was 23.7% and 25.9%,respectively.CONCLUSIONS The drug resistance rate in isolates derived from infected urinary tract of patients in mountain area was lower than in plain region of Hubei Province.

Objective To study the prevalence of dilated cardiomyopathy and the quasi-latent Keshan disease in villages of non-endemic areas of six Keshan disease endemic provinces in China,and to provide reference values for proposing a elimination standard of keshan disease.Methods County,township and village was selected as the study area by using multi-stage sampling in non-Keshan disease areas of Sichuan,Shanxi,Henan,Shandong and in Keshan disease areas of Chongqing and Yunnan.In each county two townships were selected and in each township one village was chosen.The residents of the villages sampled were surveyed by questionnaire,physical examination,electrocardiogram (ECG) and cardiac echocardiography.Suspected dilated cardiomyopathy patients had chest X-ray.Dilated cardiomyopathy patients were diagnosed according to the criteria proposed by 2006 World Health Organization/International Society and Federation of Cardiology (WHO/ISFC).Results The number of investigated villages was 126 and 54 139 people were surveyed by questionnaire and clinical examination.Ten patients with dilated cardiomyopathy were found,the prevalence was 18.47/100 000(10/54 139),and its 95％ confidence interval was 18.11/100 000-18.84/100 000.A total of 197 patients with quasi-latent Keshan disease were found,the prevalence was 363.88/100 000 (197/54 139),and its 95％ confidence interval was 362.27/100 000-365.49/ 100 000.The prevalence of male quasi-latent Keshan disease was 353.34/100 000(83/23 490) and of female was 372.07/100 000(114/30 639).The number of subjects with normal and abnormal ECG was 45 222 and 8917,respectively,and the rate of abnormal ECG was 16.47％.The highest rate of abnormal ECG was 38.28％ (1585/4141) in Chongqing.The lowest rate of abnormal ECG was 8.10％ (1175/14 507) in Yunnan.The highest detection rate of T wave and ST segment changes was 4.67％ (2528/54 139).In abnormal ECG indices,the detection rate of Henan,Shandong and Chongqing was higher,and all of them were higher than 10.0％.Conclusions We suggest that the reference baselines of dilated cardiomyopathy and quasi-latent Keshan disease in Keshan disease areas of the six provinces in the south of China be 18.47/100 000 and 363.88/100 000,respectively.
