Objective:To study the expression of Pleiotrophin and Midkine protein in endometrium of endometriosis and its clinical significance.Methods:Expressions of Pleiotrophin and Midkine protein were examined by immunohistochemical staining method in 30 endometrial samples of endometriosis(study group) and 29 endometrium of uterine fibroid(control group).Result:Pleiotrophin protein mainly expressed in the membrane and plasma of glandular epithelium of endometrium.Midkine protein mainly expressed in the plasma of grandular epithelium of endometrium and expressed in nuclei in some samples.The expression of Pleiotrophin and Midkine protein in endometriosis was significantly higher than that in the control group(P

Objective:To investigate the risk factors of preterm premature ruPture of membrane(PPROM) and their pregnancy outcomes.Methods:The clinical data of 95 cases of patients with PPROM admitted and treated in our hospital from October 2013 to July 2016 were collected,which were divided into two groups,observation group(gestational week 28-33 +6 weeks) and control group(gestational week 34-36 +6 weeks).The risk factors of PPROM,delivery method and pregnancy outcomes were analyzed.Results:Genital tract infection was the main risk factor of PPROM(33.68％).of the incidences of cesarean delivery,neonatal asphyxia,neonatal infections and neonatal death in observation group were significantly higher than those of control group,the differences were statistically significant(P ＜ 0.05).The intrauterine infection and puerperal infection rates of observation group of were higher than those of control group,but differences were not statistically significant (P ＞ 0.05).Conclusions:Reproductive tract infections is the most important risk factor of PPROM.The purpose of active treatment including tocolytic therapy and prevention of infection for the patients with PPROM less than 34 weeks is to prolong the gestational weeks,to reduce the rate of neonatal complication,and to improve the pregnancy outcome.

Objective To study the effect of acarbose on vascular endothelial function in patients with impaired glucose tolerance (IGT).Methods Fifty-six cases with IGT were chosen by OGTT,and they were divided into control group(27 cases) and therapy group(29 cases) by systematic sampling.The patients in control group were received placebo,the patients in therapy group were given acarbose 25-50 rug,3 times daily for 12 weeks.The body mass index (BMI),blood fat,fasting blood glucose (FPG),fasting insulin (FINS),glycosylated hemoglobin (HbA1c),high sensitivity C-reactive protein (hs-CRP),von Willebrand factor (vWF),2 h post-meal glucose (2hPG),2 h post-meal insulin (2hINS) and brachial artery endothelium-dependent dilation (EDD) was detected before and after treatment in two groups.Results Compared with that before treatment,BMI,2hPG,2hINS,HbA1c,hs-CRP and vWF were decreased and brachial artery EDD was improved after treatment in therapy group[ (24.69 ± 2.62) kg/m2 vs.(22.02 ± 2.59)kg/m2,(9.26 ± 1.02) mmol/L vs.(7.43 ± 0.95) mmol/L,(42.17 ± 9.98) U/L vs.(34.76 ± 9.86) U/L,(6.03 ±0.67)％ vs.(5.37 ±0.56)％,(5.45 ± 1.93) mg/L vs.(4.52 ± 1.55) mg/L,(187.22 ±26.57)％ vs.(165.13 ± 23.86)％,(6.08 ± 1.22)％ vs.(7.94 ± 1.25)％ ] (P ＜ 0.05 or ＜ 0.01).There was no significant difference before and after treatment in control group (P ＞ 0.05).Conclusion Acarbose can improve brachial artery EDD in patients with IGT by increasing insulin sensitivity and decreasing postprandial hyperglycemia and inflammatory factor,which delays the progression of diabetic mellitus and atherosclerosis.

OBJECTIVE:To explore the treatment effect and complication prevention of various stent materials for intracranial arteriostenosis.METHODS:A computer-based online search of Science Direct and Ei database (1998-01/2009-10) was performed for English articles with the key words of "intracranial arteriostenosis,stent placement" In addition,CNKI and CBM database (1998-01/2009-10) were searched for related Chinese articles with the same key words in Chinese.Moreover,related works were manually searched.Studies regarding various stent materials for intracranial arteriostenosis were included,including basic and clinical experiments.RESULTS:Multicenter studies of worldwide show that stent implantation displays obvious advantages in treating carotid artery stenosis compared with carotid endarterectomy.Recently,with developing of balloon and stent compliance,as well as stent technology,and application of various novel materials and cerebral protection device,stent has become a safe and effective therapy for intracranial arteriostenosis.However,complications following stent implantation,such as restenosis,ischemic stroke,cerebral hemorrhage hypertransfusion syndrome,and cerebral angiospasm,limit its application.CONCLUSION:The safety and efficacy of intracranial stent implantation remains validation of multicenter and perspective studies.High incidence of restenosis following stent implantation requires further improvement.

Objective To compare the clinical curative effect between sequential therapy and triple therapy for helicobacter pylori positive peptic ulcer.Methods 92 patients with peptic dcer were randomly divided into the observation group and the control group,46 cases in each group.The observation group was treated with sequential therapy,control group with triple therapy.The two groups were observed and compared in helicobacter pylori eradication rate,ulcer healing and relief of symptoms.Results After 4 weeks treatment,the observation group Hp clearance rate was 93.5％ (43/46),ulcer healing rate 91.3％ (42/46),the control group were 73.9％ (34/46),78.3％(36/46),two groups had significant differences(x2 =2.714,3.028,all P ＜ 0.05) ;observation group after treatment of symptomatic integral average (0.94 ± 0.21),and the control group (0.92 ± 0.17) divided the difference was not statistically significant (t =0.483,P ＞ 0.05).Conclusion The sequential therapy on helicobacter pylori positive peptic ulcer curative effect is remarkable,and can be more effective in the eradication of helicobacter pylori infection,promote ulcer healing.

Objective To investigate the value of CT and mammography for diagnosing breast masses.Methods 61 cases with breast mass confirmed pathologically were studied comparatively. The diagnostic accuracy was compared between the two mentioned diagnostic methods.Results The qualitative accuracy of CT in diagnosis of breast cancer, galactocele, lipoma, fibroadenoma, gynecomastia, breast hyperplasia was 80%(8/10), 100%(2/2), 100%(1/1), 100%(27/27), 100%(7/7), 100%(14/14), respectively. The qualitative accuracy of mammography in diagnosis of the above lesions was 70%(7/10), 50%(1/2), 0%(0/1), 81%(22/27), 43%(3/7), 71%(10/14), respectively. In the cases of breast cancer, mammography could detect clustered microcalcification foci in 4 of the 10 cases(40%). But CT could detect none of them. Mammography was superior to CT in demonstrating cluster microcalcifications which are important basis for diagnosing breast cancer. The overall accuracy of CT and mammography for diagnosing breast masses were 97% and 71%.Conclusion CT has a higher accuracy than mammography in determining the nature of breast mass. The synthetic application of both the two methods may raise the diagnostic level for early stage breast cancer.

The paper introduces using MedlineR to carry out data mining from Medline, for observing the gene relation, and using Pajek to realize the visualization of the results. Practice proofs that MedlineR could help researchers come up with assumptions in the field that they are interested in, and get a visual fingerprint. These results are the bases to go to more complex literature data mining and an important supplementary to experimental methods.
