Objective To determine contact allergens and their clinical significance in patients with dermatitis or eczema in Wuxi city.MethodsPatch test was conducted in 1065 patients with a clinical diagnosis of dermatitis or eczema.A statistical analysis was carried out.Results Positive patch test reactions were observed in 83.19％ of the patients,with no statistical differences in the frequency of positive patch test reactions between female and male patients or between patients of different age groups.The most frequent 6 allergens were potassium dichromate,cobalt chloride,nickle sulfate,formaldehyde,carba mix and fragrance mix in these patients.Female patients showed a higher frequency of positive patch test reaction to nickle sulfate and formaldehyde,but a lower frequency to potassium dichromate and carba mix compared with male patients (all P＜ 0.01 ); young,middle-aged,and old patients exhibited an increased frequency of positive reaction to cobaly chloride compared with child patients,while young and middle-aged patients showed a decreased frequency to nickel sulfate compared with child patients (all P ＜ 0.05).Conclusion Potassium dichromate,cobalt chloride,nickle sulfate,formaldehyde,carba mix and fragrance mix are the main allergens causing dermatitis and eczema in Wuxi city.

Objective To investigate the prevalence and distribution of deafness gene mutations by the joint screening of deafness-related genes and hearing in Wuhan .Methods A total of 117930 newborns born in 2014 and 2015 volunteered to participate in this study .Besides traditional hearing screening ,heel blood of all subjects were collected to detect four sites of three common deafness genes GJB 2 (235delC ) ,SLC26A4 (919 -2A > G ) ,and DNA 12SrRNA(1555A>G ,1494C> T) .Results The total mutation rate of deafness gene was 3 .00％ in 117930 newborns .The highest spots were GJB2235delC and SLC26A4919-2 mutation .A total of 109036 newborns pas-sed the combined screenings ,and 5353 newborns passed the gene screening ,but failed hearing screening .A total of 32131 newborns passed the hearing screening with gene mutation ,while 310 newborns failed in both .Newborns with gene mutation were more likely to fail hearing screening .Conclusion This study indicates that neonatal deafness gene screening in combination with hearing screening not only can effectively improve the detection rate of hearing loss or high risk children ,but also can provide detailed genetic information to promote the popularization and application of such concurrent screenings .

Under the condition of normalized epidemic prevention and control, the hospital should optimize the pre-operation management process of day surgery according to the requirements of epidemic prevention and control and the needs of patients. The authors analyzed the problems existing in the pre operation management process of daytime operation in the past, and constructed the pre-operation management process of daytime operation from two aspects of wartime early warning management and peacetime process optimization. After the process optimization, the 24-hour discharge rate of patients with day surgery was improved, the non-surgery discharge rate and the rate of missed appointment were reduced. While strengthening the prevention and control of the epidemic, the process could promote the continuous improvement of the quality of day surgery management.

Objective:To explore the effect of intervention of E-cadherin (E-cad) and B-lymphoma Moloney murine leukemia virus insertion region-1 (Bmi-1) mediated by transcription activator-like effector nuclease (TALEN) on the biological behaviors ofnasopharyngeal carcinoma cells.Methods:Multi-locus gene targeting vectors pUC-DS1-CMV-E-cad-2A-Neo-DS2 and pUC-DS1-Bmi-1 shRNA-Zeo-DS2 were constructed,and the E-cad and Bmi-1 targeting vectors were transferred with TALEN plasmids to CNE-2 cells individually or simultaneously.The integration of target genes were detected by PCR,the expressions of E-cad and Bmi-1 were detected by Western blot.The changes of cell proliferation were detected by cell counting kit-8 (CCK-8) assay.T-he cell cycle and apoptosis were detected by flow cytometry.The cell migration and invasion were detected by Transwell assay.Results:The E-cad and Bmi-1 shRNA expression elements were successfully integrated into the genome of CNE-2 cells,the protein expression level of E-cad was up-regulated,and the protein expression level of Bmi-1 was down-regulated.The intervention of E-cad and Bmi-1 didn't affect the proliferation,cell cycle and apoptosis of CNE-2 cells,but it significantly inhibited the migration and invasion ability of CNE-2 cells.Furthermore,the intervention of E-cad and Bmi-1 together significantly inhibited the migration ability of nasopharyngeal carcinoma cells compared with the intervention of E-cad or Bmi-1 alone (all P＜0.01).Conclusion:The joint intervention of E-cad and Bmi-1 mediated by TALEN can effectively inhibit the migration and invasion of nasopharyngeal carcinoma cells in vitro,which may lay the preliminary experimental basis for gene therapy of human cancer.

Objective:To analyze the incidence of stillbirth and the associated factors in pregnancy among pregnant residents in Wuhan.Methods:A previous birth cohort was retrospectively reviewed. The cohort was based on Wuhan Maternal and Child Information System, and the perinatal information of pregnant residents in Wuhan from January 1, 2011, to September 30, 2017 and information of selected cases was collected, including socio-demographic characteristics, pregnant history, and healthcare information during pregnancy and labor. Data on stillbirth, including fetal death in uterus and in labor, were selected for this study. Chi-square test was adopted for comparing the differences in pregnancy-related factors between live birth and stillbirth, and binary logistic regressions for exploring the influencing factors associated with the occurrence of stillbirth. Results:A total of 509 057 deliveries in Wuhan were included in this study, including 505 839 live births and 3 218 stillbirths (3 155 after exclusion of fetal death in labor), with an overall incidence of stillbirth of 6.32‰(3 218/509 057), and an annual incidence between 4.90‰ to 8.11‰. Statistically significant differences were found between the live birth and stillbirth group in the following items: maternal age [<25 years old: 19.28% (97 544/505 839) vs 19.36% (623/3 218); 25-30 years old: 48.45% (245 077/505 839) vs 45.15% (1 453/3 218); 30-35 years old: 26.09% (131 952/505 839) vs 26.29% (846/3 218); >35 years old: 6.18% (31 266/505 839) vs 9.20% (296/3 218)], educational background [middle school or below: 22.90% (115 833/505 839) vs 22.03% (709/3 218); high school: 36.37% (183 978/505 839) vs 38.72% (1 246/3 218); college or above: 40.73% (206 028/505 839) vs 39.25% (1 263/3 218)], occupation [brainworker or professionals: 33.51% (169 514/505 839) vs 31.54% (1 015/3 218); manual or freelance worker: 66.38% (335 763/505 839) vs 68.34% (2 199/3 218)], residential area [urban area: 70.00% (354 365/505 839) vs 76.32% (2 456/3 218); rural area: 30.00% (151 474/505 839) vs 23.68%(762/3 218)], and time of conception [spring (March to May): 24.27% (122 746/505 839) vs 24.08% (775/3 218); summer (June to August): 24.09% (121 867/505 839) vs 23.87% (768/3 218); fall (September to November): 26.69% (135 012/505 839) vs 25.08% (807/3 218); winter (December to next February): 24.95% (126 214/505 839) vs 26.97% (868/3 218)] (all P<0.05), but no significant difference was found in fetal gender ( P>0.05). Besides, gravidity [once: 49.32% (249 484/505 839) vs 47.02% (1 513/3 218); over twice: 50.68% (256 355/505 839) vs 52.98% (1 705/3 218)], parity [once: 73.60% (372 316/505 839) vs 77.07% (2 480/3 218); over twice: 26.40% (133 523/505 839) vs 22.93% (738/3 218)], history of stillbirth [0.33% (842/256 355) vs 0.65% (11/1 705)], hypertensive disorders in pregnancy [3.25% (16 464/505 839) vs 5.59% (180/3 218)], first trimester vaginal bleeding [2.02% (10 251/505 839) vs 2.61% (84/3 218)], placenta previa [0.98% (4 963/505 491) vs 2.64% (53/2 009)], and oligohydramnios [2.52% (12 764/505 839) vs 1.90% (61/3 218)] differed significantly between the two groups (all P<0.05). However, no significant difference was found between the two groups in terms of the proportion of women with gestational diabetes mellitus and previous spontaneous abortion (both P>0.05). After exclusion of fetal death in labor from the 3 218 stillbirths, the same results were achieved. Binary logistic regression analysis showed that women who were over 30 years old (30-35 years old: OR=1.42, 95% CI: 1.30-1.56; >35 years old: OR=2.59, 95% CI: 2.25-2.98), with a high school degree or below (middle school or below: OR=1.37, 95% CI: 1.21-1.55; high school: OR=1.28, 95% CI: 1.16-1.42), manual or freelance worker ( OR=1.18, 95% CI: 1.07-1.31), in the urban area ( OR=1.43, 95% CI:1.31-1.57), and gravidity ≥ 2 times ( OR=1.32, 95% CI: 1.21-1.43), primiparity ( OR=1.76, 95% CI: 1.58-1.96), gestational hypertension ( OR=2.80, 95% CI: 2.40-3.27), vaginal bleeding in the first trimester ( OR=1.35, 95% CI: 1.08-1.68), placenta previa ( OR=10.86, 95% CI: 8.84-13.35) and history of stillbirth ( OR=2.27, 95% CI: 1.30-3.98) were all risk factors of stillbirth. Conclusion:Pregnant women who were over 30 years old, less educated, manual worker or freelance or with a history of adverse pregnancy, vaginal bleeding in the first trimester, hypertension in pregnancy, and placenta previa are at higher risk of stillbirth
