Objective To know the cognition,attitude and needs among middle-aged andaged women with urinary incontinence(UI) in communities. Methods A questionnaire survey wasconducted in 66 middle-aged and aged women with UI in two communities and the results were an-alyzed. Results Most patients lacked the knowledge of UI;UI had impact on their physical andmental heahh.Must patients wished to know about the treatment knowledge,and health education of med-ical staff was the most promising way.The mastering degree of knowledge about disease was not related tothe serious degree of disease and age,but was positively related to education degree and economic income.Conclusions We should publicize the knowledge about UI and provide health education and emotionalsupport to patients.And we should emphasize the training about UI among medical staff.

Objective To investigate the distribution and drug resistance of pathogens for hospital-acquired urinary tract infections between patients in internal medicine wards and in surgical wards .Methods A total of 586 midstream urine samples were collected from patients in the First Municipal Hospital of Qinhuangdao during January 2012 and December 2014.Vitek 2 Compact system was applied in bacteria identification and drug sensitivity tests .Excel and SPSS 11.5 software were applied for data analysis . Results A total of 661 strains were isolated , in which 404 strains were from internal medicine wards and 257 strains were from surgical wards .Escherichia coli (44.6%vs.33.1%) and Enterococcus (23.0%vs. 16.3%) infections were more common in the internal medicine wards (χ2 =8.620 and 4.309, P<0.05), while the occurrence of Pseudomonas aeruginosa infection (4.0%vs.24.5%) was higher in surgical wards (χ2 =63.056, P <0.01).Escherichia coli and Klebsiella pneumonia strains were highly sensitive to piperacillin/tazobactam, cefptetan, amikacin, imipenem, and meropenem, and the sensitivity rates were from 85% to 100.0%.The sensitivity rates of Escherichia coli to ampicillin/sulbactam, levofloxacin and ciprofloxacin were <30%, and strains from surgical wards had lower sensitivity rates to these drug than those isolated from internal medicine wards (χ2 =4.987, 4.575 and 5.359, P<0.05).The sensitivity rates of Klebsiella pneumonia isolated from internal medicine wards to ceftazidime , gentamicin and aztreonam were 68.8%, 60.6% and 69.7%, which were higher than those isolated from surgical wards (36.0%, 32.0%, and 40.0%), and the differences were of statistical significance (χ2 =6.068,4.661 and 5.115, P<0.05).Pseudomonas aeruginosa strains were highly sensitive to piperacillin/tazobactam and amikacin, and the susceptibilities of strains isolated from surgical wards (98.4%and 96.8%) were higher than those isolated from internal medicine wards (75.0% and 81.3%) (χ2 =11.797 and 5.221, P <0.05). Pseudomonas aeruginosa strains isolated from surgical wards were also highly sensitive to cefepime (92.1%), but the sensitive rate of strains from internal medicine wards was only 37.5%, and the difference was of statistical significance (χ2 =24.696, P<0.01).Enterococcus faecium and Enterococcus faecalis were sensitive to tigecycline , vancomycin and linezolid with the sensitivity rates over 95%.Except quinupristin/dalfopristin and tetracycline , the sensitivities of Enterococcus faecalis to other antibiotics were higher than Enterococcus faecium.Susceptibility of Enterococcus faecium from surgical wards (33.3%) to moxifloxacin was lower than those from internal medicine wards (70.8%), and the difference was of statistical significance (χ2 =4.629, P <0.05).Conclusion There are differences in distribution and antimicrobial susceptibility of pathogens isolated from internal medicine wards and from surgical wards .

Objective To observe the effect of pregnancy double loop cerclage for cervical incompetence. Methods 80 cases of cervical function incompetence according to the type of surgery were divided into two groups, 40 cases in each group,15 -20 weeks of surgery in pregnancy,the treatment group underwent double loop cerclage, the control group underwent McDonald single cerclage.The operation,postoperative cervical length and pregnancy outcome of the two groups were observed.Results There was no difference in operation time and blood loss between the two groups.The length of cervix in the treatment group was (4.63 ±0.52)cm,which was longer than (3.71 ± 0.82)cm of the control group(t =2.106,P <0.05).Pregnancy outcome:20 cases of the treatment group in term birth (50%),preterm birth in 18 cases (45%)(34 -37 weeks in 12 cases,28 -34 weeks in 6 cases),fetal survival in 36 cases (90%),less than 28 weeks pregnant inevitable abortion in 2 cases (5%),abortion did not survive.Average delivery gestational age was 35.2 weeks,and preoperative average abortion pregnant weeks contrast,treatment group delivery gestational weeks extended 13.5 weeks,the average weight of newborns was (3 200 ±200)g.The control group of full -term delivery was 14 cases (35%),premature in 20 cases (50%)(34 -37 weeks in 7 cases and 13 cases of 28 -34 weeks),fetal survival in 33 cases (82.5%),less than 28 weeks pregnant inevitable abortion in 4 cases (10%),abortion did not survive.Average delivery gestational age was 33.2 weeks,compared with the average abortion weeks before operation,the gestational age of the control group was extended by 11.5 weeks.The weight of newborn was (2 900 ±300)g.In the treatment group,the term labor rate,fetal survival rate,neonatal weight were higher than those of the control group,the difference was statistically significant (χ2 =7.83,P <0.05).Conclusion The second trimester cervical double cerclage can maintain effective cervical length,prolong gestational age,improve perinatal survival rate.

Objective:To explore the functions of cytokines and TM in the pathogenesis of acute cerebral infarction.Methods:The levels of IL-1、IL-6 、TNF and TM were detected by ELISA in 55 patients with acute cerebral infarction.Results:The levels of IL-1、IL-6 、TNF and TM were increased significantly in the patients with acute cerebral infarction in comparision with the controls ( P

AIM:To investigate the expression of GAP-43 mRNA and protein of the motor neurons in spinal cord following the brachial plexus avulsion injury.METHODS: In the present study,three kinds of models of brachial plexus avulsion injury were made: right C7 anterior root avulsion(group A),C7 anterior root avulsion with right C5-T1 posterior roots breaking(group B),right C7 anterior root avulsion with hemi-transect between C5 and C6 segment of spinal cord(group C).The expression of GAP-43 mRNA in anterior horn of spinal cord was detected at 14 days after operation by SYBR green quantification RT-PCR technique.The amounts of GAP-43 positive neurons in spinal cord were detected at 1,3,7 and 14 days after operation by immunohistochemistry technique.RESULTS: In control group,the expression of GAP-43 mRNA was very low in anterior horn.By 14 days after operation,the expression of GAP-43 mRNA was evidently up-regulated compared with control group.GAP-43 positive neuron was observed in control group at 1st day and 3rd day after operation.GAP-43 positive neurons appeared at 7th day and peaked at 14th day after operation.The expression of GAP-43 mRNA and protein were maximum in group C,group B was the lowest.CONCLUSION: The expression of GAP-43 mRNA and GAP-43 protein were up-regulated following brachial plexus injury.The expression of GAP-43 protein results from the recombination of proteins.GAP-43 is closely related to the axon regeneration and functional reconstruction.

Objective To analyze the pregnancy outcome of laparoscopic cervical cerclage before pregnancy, discuss the clinical value of the treatment of cervical incompetence.Methods 40 cases with cervical insufficiency during 2012.1 -2016.3 before pregnancy underwent laparoscopic ligation.All patients had a history of abortion or premature birth,and the average gestational age was 23.7 weeks.Preoperative cervical length was less than 2.5cm. The operation condition and the pregnancy outcome after operation were observed.Results The average time of oper-ation was 35.6(40.2 ±10.4)min and the amount of bleeding was 10.3(15.7 ±3.2)mL.Postoperative pregnancy cervical average length was 3.61 (4.35 ±0.52)cm.Pregnancy outcome:37 weeks of gestation and above delivery 20 cases (50.0%).34 -37 weeks 16 cases (40.0%),28 -34 weeks in 3 cases,received cesarean section,the aver-age gestational was 35.6 weeks.Compared with the preoperative abortion,the gestational week of delivery was pro-longed by 12.1 weeks.Neonatal survival in 38 cases (95.0%),1 case of gestational 28 +3 weeks premature death. Neonatal birth weight was 2 800(3 079 ±500)g;1 case (2.5%)was difficult to avoid abortion at 23 weeks of gesta-tion.Conclusion Laparoscopic pre -pregnancy cervical cerclage suture in cervix mouth,postoperative can maintain effective cervical length,prolong gestational age,improve the pregnancy outcome,can be used as effective treatment for the pregnant cerclage failure or cervical length less than 2.5cm of cervical insufficiency patients.
