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 investigate the tagging condition in medication of special population in package inserts in order to give reference for rational drug use of special population. METHODS: 389 pieces of common Chinese and western medicine package inserts of our inpatient and out-patient dispensaries were randomly collected and analyzed statistically in terms of the content of package inserts for special population, including pregnant and lactant women, children and the aged. RESULTS: A part of medication items of special population in package inserts had deficiency. According to the classification of dosage form, the tagging rate of injection exceeded other dosage forms reached to more than 90%, except of medication items for children. The tagging rate of oral formulation arrived at more than 90% only in terms of contraindications and cautions. According to the classification of manufacturer, the tagging rate of domestic drugs was kept at the low level while that of imported drugs exceeded 90%. CONCLUSIONS: Package inserts need to be improved with the effort of drug supervision management department, drug production department and population of using drugs to guarantee the safety of drug use in special population.

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.

Choroidal neovascularization( CNV) is a common severe complication of ocular fundus diseases, with great potentiality to cause blindness. The treatments of CNV include photodynamic therapy ( PDT ) and anti-vascular endothelial growth factor( VEGF) therapy. However, PDT produces little visual benefits, and may result in ischemia, inflammatory responses, even the secondary expressions of VEGF. Anti-VEGF therapy sustained visual efficiency by repeated injections, causing economic burden and adverse effects related to injection. Recently, PDT combined with anti-VEGF therapy has progressed in laboratory and clinical research. Therefore, the combined modality therapy became one of the treatment options for CNV. In order to reduce the side effects of mono -therapy, further study is required to determine appropriate combinations and dosage.

Objective To evaluate the diagnostic value of blue laser imaging( BLI) combined with magnifying endoscopy for precancerous lesions and early gastric cancers. Methods From September 2015 to May 2016, a total of 249 gastric lesions detected with conventional white light endoscopy ( WLE) on the basis of the assessment of mucosal shape and color were enrolled in this study. The pathological results were used as golden standard,and diagnostic accuracy rates of precancerous lesions or early cancers by white light magnification alone,BLI?contrast magnification and BLI?bright magnifier were determined according to the VS criteria. The concordance between endoscopic diagnosis and pathological diagnosis was evaluated through the agreement ( Kappa ) test, and diagnostic value was compared with McNemar paired Chi?square test. Results Pathological examination showed chronic gastritis in 149 lesions, intestinal metaplasia in 67, low grade intra?epithelial neoplasia in 8, and high grade intra?epithelial neoplasia or early cancer in 25. The concordance rates of lesions were 76?7% for white light magnification alone, 85?1% for BLI?contrast magnification, and 86?7% for BLI?bright magnification. Kappa values were 0?571, 0?730, and 0?760 respectively. For the screening of high grade intra?epithelial neoplasia or early cancer, the diagnostic sensitivities were 72?0%, 92?0%, and 92?0%, respectively, the specificities were 95?5%, 98?2%, and 99?1%,the consistencies were 93?2%,97?6%,98?4%,and the Kappa values were 0?642,0?871,and 0?911. In contrast to white light magnification alone,the concordance between endoscopic diagnosis and pathological diagnosis of BLI?contrast magnification and BLI?bright magnification was significantly higher(P<0?05).And in the diagnosis of high?grade intraepithelial neoplasia or early gastric cancer,the concordance between endoscopic diagnosis and pathological diagnosis of BLI?contrast magnification and BLI?bright magnification was higher than that of white light magnification alone( P<0?05) . Conclusion BLI combined with magnifying endoscopy may improve the diagnostic accuracy of early gastric cancer and precancerous lesions.
