Objective To compare the diagnostic values of the detection of urine exfoliated cells by FISH and cytology technolo‐gy in bladder urothelial tumor .Methods The combination probes of CSP3/CSP7 and GLPp16/CSP17 were both used in the FISH detection of urine exfoliated cells from suspected patients with bladder urothelial tumor .The urine exfoliated cells were detected by cytology technology at the same time .The sensitivity and the specificity of the two methods were compared .Results The sensitivi‐ty and specificity of FISH for bladder urothelial tumor screening were 92 .5% and 85 .0% respectively ,and those of cytology tech‐nology were 27 .5% and 90 .0% respectively .The sensitivity of FISH was significantly higher than that of cytology technology (P<0 .05) ,however ,the specificity differences between FISH and cytology technology were not statistically significant (P>0 .05) .Conclusion FISH is expected to become a new method for the screening of bladder urothelial tumor .

With the increasingly tense doctor-patient relationship,the practice teaching of laboratory medicine has obviously been affected.For example,the practice teachings systems do not adapt to the updated situations,and practice teaching has been simplified and communication training ignored.In order to deal with these problems and ensure the goals of practice teaching,various measures have been taken in training hospitals.Firstly,the practice system has been further improved and implemented effectively by strengthening mobilization and adopting qualification licensing before practice and interaction practice between teachers and students and regular communication between school and training hospital during practice and strict assessment after practice.Secondly,medical ethics educations and laboratory biological safety have been strengthened.Thirdly,the modem automation and classic morphology should be integrated.Finally,the ability of communication between medical laboratory and doctor and patients should be cultivated,and so on.These measures are to ensure the effect of the practice teaching and cultivate excellent students.

Objective To evaluate the maternal age at delivery in Beijing and the effect of maternal age on pregnancy outcomes.Methods A retrospective analysis was conducted on 14 970 singleton pregnancies from 15 hospitals in Beijing from June 20th to November 30th in 2013.These hospitals were sorted by the numbers of delivery and chosen as clusters by systemic cluster sampling method.The data of age,diagnosis with gestational diabetes mellitus (GDM) and pre-eclampsia (PE),neonatal birth weight,gestational age at delivery,postpartum hemorrhage and infants admitted to the neonatal ICU (NICU) were collected.The 14 970 women were divided into 5 groups according to their ages at delivery:(1) less than 20 years (n=205),(2)20-＜30 years (n=9 228),(3)30-＜35 years (n=4 365),(4)35-＜40 years (n=1 017),and (5) 40 years and older (n=155).T-test and x2 test were used for between-group comparison,and logistic regression analysis was used to examine the association between age and the risk of adverse pregnancy outcomes.Results (1) The mean maternal age at delivery in 2013 in Beijing was (28±4) years old.Among them,205 (1.4％,205/14 970) delivered under 20 years of age;1 172 (7.8％,1 172/14 970) ≥35 years;and 155 (1.O％,155/14 970) at 40 years and older.(2) The prevalence of diabetes,hypertension,overweight and obesity increased with age,and the incidence of these conditions were 3.4％,4.3％ and 31.4％ in women with advanced age,respectively.(3) Compared with 20-＜30 years group,less than 20 years was associated with significantly lower incidence of GDM [adjust OR (aOR)=0.393,95％ CI:0.222-0.696] and cesarean section rate (aOR=0.549,95％CI:0.391-0.771),and higher incidence of preterm birth (aOR=2.144,95％CI:1.256-3.662).Moreover,30-＜35 years,35-＜40 years and 40 years and older groups all had significantly higher risk of GDM (30-34 years,aOR=1.513,95％CI:1.374-1.666;35-＜40 years,aOR=2.094,95％CI:1.786-2.455;≥40 years,aOR=2.174,95％CI:1.492-3.167),preterm birth (aOR=1.219,95％CI:1.021-1.455;aOR=1.644,95％CI:1.251-2.161;aOR=2.141,95％CI:1.209-3.792),cesarean section (aOR=1.373,95％ CI:1.268-1.486;aOR=2.960,95％ CI:2.550-3.435;aOR=4.332,95％CI:2.920-6.426) and NICU admission rate (aOR=1.236,95％CI:1.059-1.443;aOR=1.337,95％CI:1.018-1.756;aOR=2.389,95％CI:1.385-4.121),when compared to the 20-＜30 years of age group.Higher incidence of PE (aOR=1.292,95％CI:1.007-1.659) and postpartum hemorrhage (aOR=1.224,95％CI:1.048-1.429) were also noted in women of 30-＜35 years,compared to 20-＜30 years group respectively.Conclusion Both advanced maternal age and adolescent pregnancy are associated with increasing risk of adverse pregnancy outcomes.

Clear thermoplastic retainer is one of the most commonly used retention devices in orthodontics.However, studies about the electromyography (EMG) of temporalis muscle (TM) and masseter muscle (MM) in people with clear thermoplastic retainer are few. The purpose of this study was to observe the influence of clear thermoplastic retainer on the EMG of TM and MM in mandible posture position (MPP) , speaking [s] ,[z] and [a]. Choose people according to the standards, decide the situation by preliminary experiment. The EMG of TM, MM was studied before and after clear thermoplastic retainer was worn. Variance analysis was used to evaluate the differences. The results revealed that the EMG activity of TM?MM, viewed in MPP and when people said [s] ,[z] , was higher after clear thermoplastic retainer was worn. When people said [a], there was no significant difference.

Objective To learn students' satisfaction with the general education courses, discuss the problems in comprehensive general education courses in local medical colleges , and provide the basis and reference for the medical general education courses reform. Methods Using the stratified random sampling method, self-designed questionnaire to local medical colleges of 575 different professions stu-dents. The questionnaire had the total of 54 topics whose contents were related to the basic situation aware-ness and satisfaction, the demand for general education courses, general education curriculum problems and suggestions. The survey data were analyzed using SPSS 19.0 software and the results were expressed by the relative number(rate and percentage). The differences between different majors and different grade student satisfaction were analyzed by using rank-sum test, showing statistical significance(P<0.05). Results The total satisfaction was not very high, only 219 students(38%) were satisfied with general curriculum;256 students(45%) thought it didn't matter whether to set general education courses;100 students(17%) were not satisfied. In addition, satisfaction with different grades was undifferentiated (P=0.798), but there was a statistical difference among the students of different professions(P=0.007). Conclusion The general education curriculum of medical schools should not blindly pursue being wide and full. Instead, it should be built from three aspects such as core curriculum, flexible teaching methods, teaching methods reform to enhance teaching effectiveness.

Objective To investigate the distribution and drug resistance of common pathogens in Xinjiang ,aare so as to provide references for reasonable use of antibiotics .Methods The strains of common pathogens isolated from patients in the First Teaching Hospital of Xingjiang Medical University from 2012 to 2013 were collected ,and the drug susceptibility testing were performed by K‐B methods recommended by CLSI .Results Totally 18 374 strains were isolated ,among them 13 323 strains were gram negative and 5 051 strains were gram positive .Escherichia coli ,Klebsiella pneumoniae ,Staphylococcus aureus ,Acinetobacter baumannii and Pseudomonas aeruginosa occupied the top 5 .Most of strains were isolated from sputum (accounted for 36 .1% ) .Escherichia coli and Klebsiella pneumoniae showed high resistance rate to cefazolin sodium ,cefotaxime and quinolones .The detection rate of ESBLs pro‐ducing Escherichia coli and Klebsiella pneumoniae were 48 .4% and 41 .7% ,respectively .The resistance rate of Pseudomonas aerug‐inosa to commonly used antibiotics was 10 .0% ~20 .0% .Methicillin resistant staphylococcus aureus(MRSA) accounted for 44 .7%of all Staphylococcus aureus ,and no strains of Staphylococcus resistant to vancomycin ,teicoplanin and Linezolid were found .Conclu‐sion Gram negative bacteria are the most common strains isolated from clinical in this area ,and strains are mainly isolated from samples of respiratory tract and genitourinary tract ,and the situation of drug resistance is severe ,which indicate the clinicians should strengthen the monitoring of drug‐resistant bacteria and promote rational use of antimicrobial agents .

Objective To investigate the clinical characteristics (social background,comorbidity,complications and outcomes of pregnancy) of multipara in Beijing area.Methods A systematic cluster sampling survey was conducted on 15 194 pregnant women who gave birth at 15 hospitals in Beijing from January to June in 2013.The age,gestational weeks at delivery,education background,geographical distribution,health insurance coverage,mode of delivery,comorbidity and complications of pregnancy,pregnant outcomes and other relevant clinical data were collected and analyzed with two-sample t test or Chi-square test.Results The proportion of multipara in Beijing area was 21.12％ (3 209/15 194),the per capita number of delivery was 1.23 (18 745/15 194).The ratio of women with higher education background,average monthly household income over 3 000 yuan,urban residence and social insurance in multipara were much lower than those in primipara (all P＜0.05).The mean maternal age of multipara was (30.02±4.88) years,pre-pregnancy body mass index was 22.24 ± 3.48,which were all higher than those of primipara [(27.82 ± 4.03) years and 21.54 ± 3.29,respectively,t=23.440 and 11.115,all P＜0.01].And the gestational weeks at delivery and mean weight gain during pregnancy of multipara was less than that of primipara [(39.15 ±1.67) vs (39.49 ± 1.67) weeks,t=-14.044,P=0.000;(14.66±6.24) vs (15.81 ± 5.86) kg,t=-9.448,P=0.000],while the levels of total cholesterol,triglyceride and low density lipoprotein-cholesterol and the incidence of macrosomia were significantly higher [(5.59± 1.14) vs (5.24± 1.15) mmol/L,(2.31± 1.38) vs (1.96± 1.34) mmol/L,(3.03±0.91) vs (2.82±0.87) mmol/L,t=12.867,15.718 and 10.275,all P＜0.01;9.29％ (298/3 209) vs 7.24％ (868/11 985),x2=14.926,P=0.000].Significantly lower incidences of abnormal amniotic fluid volume,premature rupture of membranes,fetal distress,abnormal labor and vaginal delivery (all P ＜ 0.01),but higher neonatal birth weight [(3 374.38 ±504.57) vs (3 328.39±488.70) g,t=4.839,P=0.000] and cesarean section rate [45.96％ (1 475/3 209) vs 42.49％(5 092/11 985),x2=12.477,P＜0.01] were found in multipara than in primipara.Compared with primipara,multipara had higher incidence of gestational diabetes mellitus,diabetes during pregnancy,pregnancy complicated with cardiovascular problems,hypertensive disorder complicating pregnancy [adjusted OR(95％CI):1.265 (1.135-1.411),1.799 (1.215 2.663),1.567 (1.221-2.347),1.647 (1.300-2.086),all P＜0.01].Conclusions The primipara is the major reproductive population in Beijing area.However,the multipara requires close antenatal care because of their susceptibility to pregnant complications.

Objective To evaluate the prevalence of macrosomia in Beijing in 2013 and identify its risk factors. Methods Retrospective six months analysis of 14 188 full-term singleton pregnant women from 15 hospitals with different levels in Beijing in 2013. Each participant′s demographic data and medical information were collected individually by questionnaires. Multiple logistic regression analysis was used to examine the associations between variables and the risk of macrosomia. Results (1)The total prevalence of macrosomia was 7.069%(1 003/14 188) in Beijing in 2013. (2)The prevalence varied between the 15 hospitals, the lowest was 5.36%(89/1 659), while the highest reached 8.80%(46/523). Furthermore, the incidence of macrosomia was 1.284 times (95%CI: 1.114-1.480, P=0.001) higher in the second graded hospitals than that in the tertiary hospitals. (3) Multiple logistic regression analyses showed that risk factors for macrosomia were maternal height≥160 cm (adjusted OR=1.875, 95%CI: 1.559-2.256), pre-pregnant body mass index (p-BMI) ≥24.0 kg/m2 (24.0-27.9 kg/m2:adjusted OR=1.696, 95%CI: 1.426-2.018; p-BMI≥28.0 kg/m2:adjusted OR=2.393, 95%CI: 1.831-3.127), gestational weight gain (GWG)≥15.9 kg (adjusted OR=2.462, 95%CI: 2.125-2.853), gravidity>1 (adjusted OR=1.408, 95%CI: 1.224-1.620), gestational weeks≥40 (adjusted OR=2.007, 95%CI:1.745-2.308) and gestational diabetes mellitus (adjusted OR=1.522, 95%CI:1.298-1.784). GWG≥15.9 kg, p-BMI≥28.0 kg/m2 and gestational weeks≥40 were three risk factors that had the strongest associations with macrosomia (all P<0.01). Conclusions The prevalence of macrosomia in hospitals with different levels is obvious different. Gestational weeks, p-BMI and GWG are three main controllable risk factors for macrosomia, thus should receive more attentions.

Objective To discuss the diagnosis, treatment and following up of the cervical lesions(CIN～cervical carcinoma Ia 1) during pregnancy. Methods Fifteen pregnant women with cervical lesions were reviewed from Jan 1998～Oct 2003 in our hospital. Results Among the fifteen cases, 11 were diagnosed as CIN～ cervical carcinoma Ia 1 based on biopsy results under copolscopy. Ten of the 11 cases had copolscopy repeated every 8 weeks and delivered at term. The left one woman terminated the pregnancy in the first trimester due to carcinoma in situ (CIS) invasion to glands. Among those 10 cases who progressed to term, four were stable during pregnancy (CINⅡ,CINⅢ,CIS and cervical carcinoma Ia1, one for each) and had the same pathology postpartum as antepartum; three had CIN I during pregnancy but changed to inflammation postpartum;one had CIS involved in glands prepartumly while CINⅡ～Ⅲ postpartumly; one had CINⅢ prepartumly and progressed to CIS involved in glands confirmed after conization postpartumly. One woman was missing after delivery. Conclusions Cervical lesions (CIN～Ia 1) less likely get worse during pregnancy. Conservative management is possible if regular cytology, copolscopy and bioposy when necessary are available. Re examination is necessary within two months after birth. Routine examination for women who have no pap smear within the last one year period would be helpful in detecting cervical lesions during pregnancy.
