OBJECTIVE: To explore the found ways and first diagnosis age of children with large vestibular aqueduct, and their relations with hearing loss. METHOD: Medical histories of 122 cases of children diagnosed with large vestibular aqueduct by HRCT or MRI had been collected from January 2009 to April 2014 in our hospital children's hearing diagnosis center clinic. Found ways comprise of accepting universal newborn hearing screening (UNHS) group and unaccepting UNHS group. Accepting UNHS children were divided into two ears unpassing group, single ear unpassing group and passing group. The patients in unaccepting UNHS group were divided into not sensitive to sounds, speech stunting, sudden hearing loss, and other group. Analysis the relationship between the found ways and first diagnosis age and their relations with hearing loss. RESULT: There are 84 cases (68.85%) accepting UNHS, the average age of first diagnosis was (17.24 ± 17.08) months; 37 cases (31.15%) are not accepting UNHS. The average age of first diagnosis was (30.92 ± 18.21) months. The average first diagnosis age of accepting UNHS group was more earlier than the unaccepting UNHS group. The difference was statistically signif- icant (P < 0.01). There were 57 cases (67.85%) whose two ears not pass UNHS; 15 cases (17.86%) single ear not pass; namely the referral rate was 85.71%; 12 cases (14.29%) pass the test. The first diagnosis age of passing UNHS group was more later than two ears unpassing group (P < 0.001). In the unaccepting UNHS group, the average first diagnosis age of not sensitive to sounds group (19.69 ± 11.16 months) was more earlier than words dysplasia group (37.13 ± 15.62 months) and sudden hearing loss group (47.40 ± 24.70 months) (P < 0.01). The difference in the degree of hearing loss between accepting UNHS and unaccepting UNHS group had no statistical significance (P > 0.05). In unaccepting UNHS group ,the average first diagnosis age of the mild-to-moderate hearing loss group was later than the very severe hearing loss group (P < 0.01). CONCLUSION Most of large vestibular aqueduct children can be found and receive diagnosis early by UNHS. But part of these patients with late-onset or progressive hearing loss, especially these with mild-to-moderate hearing loss cannot be found early, which should arouse our attention.

Objective To investigate the roles and mechanisms of hepatocyte nuclear factor 4α (HNF4α) in chenodeoxycholic acid (CDCA) induced gastric intestinal metaplasia (IM).Methods After the immortalized gastric mucosal epithelial cells GES-1 were stimulated with CDCA at different concentration,the changes of HNF4α,caudal-related homeobox 2 (CDX2) and trefoil factor family 3 (TFF3) expressions at mRNA and protein levels in GES-1 cells and gastric cancer cell lines (AGS,SGC7901 and BGC823) were detected by real time-polymerase chain reaction (RT-PCR) and Western blotting.After GES-1 were transfected with HNF4α short hairpin RNA (shRNA) or control shRNA,and followed by CDCA stimulation,the expressions of HNF4α,CDX2 and TFF3 at protein level were determined by Western blotting.HNF4α was overexpressed in GES-1 cells and SGC7901 cells,and HNF4α was silenced in BGC823 cell line and AGS by lentiviral vector system.The expressions of HNF4α,CDX2 and TFF3 at mRNA and protein levels were tested by RT-PCR and Western blotting.Luciferase reporter assay was used to analyze the regulation role of HNF4α on CDX2.T test was performed for statistical analysis.Results The expressions of HNF4α in GES-1,SGC7901,BGC823 and AGS cells at mRNA level were 1.00 ± 0.12,263.01±10.23,848.01±18.13 and 3 049.86±91.75,respectively.The mRNAlevels of HNF4α in AGS,BGC823 and SGC7901 cells were all higher than that of GES-1 cells,and the differences were statistically significant (t=33.23,46.72 and 25.62,all P＜0.01).The expressions of HNF4α in GES-1,SGC7901,BGC823 and AGS at protein level were consistent with mRNA level.The expressions of CDX2 and TFF3 at protein level of HNF4α shRNA transfected group were lower than those of non-HNF4α shRNA transfected group.In GES-1 cells,the expressions of HNF4α,CDX2 and TFF3 of HNF4α overexpressed group at mRNA level were 16 281.839 ± 1 843.017,6.275 ± 0.137 and 17.310± 1.533,respectively;which were all higher than those of overexpressed control group (1.000 ± 0.048,1.000 ± 0.012 and 1.000±0.108,respectively),and the differences were statistically significant (t =8.83,38.29 and 10.61,all P＜0.01).In AGS cells,the expressions of HNF4α,CDX2 and TFF3 of HNF4α silenced group at mRNA level were 0.021 ± 0.001,0.088 ± 0.007 and 0.074 ± 0.002,respectively,which were lower than those of silenced control group (1.000 ± 0.108,1.000 ± 0.131 and 1.000 ± 0.122),and the differences were statistically significant (t=9.09,6.93 and 7.57,all P＜0.01).In GES-1 overexpressed cells and AGS silenced cells,the expressions of HNF4α,CDX2,TFF3 at protein level were consistent with mRNA level.In double reporter plasmid containing the CDX2 promoter CDX2 1 (-2 000～-1 bp) and CDX2-2 (-1 510～1 bp),after transfected with HNF4α shRNA,the activities were 0.387 ± 0.013 and 0.533 ± 0.040,respectively,which were lower than those of HNF4α shRNA transfected control group (0.605 ± 0.012 and 0.882 ± 0.019),and the differences were statistically significant (t =21.49 and 13.53,both P＜0.01).Conclusion HNF4α may be involved in bile acid induced intestinal metaplasia by upregulating the expression of CDX2.

Since the first outbreak of avian influenza A(H7N9) virus in humans was identified in 2013, there have been five seasonal epidemics observed in China. An earlier start and a steep increase in the number of humans infected with H7N9 virus was observed between September and December 2016, raising great public concern in domestic and international societies. The epidemiological characteristics of the recently reported confirmed H7N9 cases were analysed. The results suggested that although more cases were reported recently, most cases in the fifth epidemic were still highly sporadically distributed without any epidemiology links; the main characteristics remained unchanged and the genetic characteristics of virus strains that were isolated in this epidemic remained similar to earlier epidemics. Interventions included live poultry market closures in several cities that reported more H7N9 cases recently.

OBJECTIVETo investigate the associations of occupational, educational and residential factors with the outcomes of in vitro fertilization -embryo transfer (IVF-ET).

METHODSA retrospective analysis was conducted among 3998 patients undergoing the first treatment with IVF-ET and 3064 perinatal infants in our center between January, 2010 and June, 2014. The relation of the patients' occupation, educational background, and residence registry with IVF-ET outcomes was analyzed.

RESULTSThe risk of abortion in the first trimester was significantly higher in female patients engaged in agriculture (OR=4.319, P=0.047). Occupation and educational background of the patients and their spouse were related with the incidence of ectopic pregnancy following IVF-ET. The total incidence rate of perinatal birth defects was 2.1% in this cohort, and was the highest in Shenzhen (5.5%) but this difference was not statistically significant (P>0.05).

CONCLUSIONThe patients' occupation and educational background are related with the outcomes of IVF-ET, suggesting the importance of health education and prenatal examination.

Objective To describe the epidemic of imported infectious diseases in China between 2013 and 2016, including the kinds of infectious diseases, affected provinces, source countries and the epidemiological characteristics, and provide scientific information for the prevention and control of imported infectious diseases. Methods Data of cases of imported infectious diseases in China from 2013 to 2016 were collected from national information reporting system of infectious diseases, Microsoft Excel 2010 and SPSS 18.0 were used to conduct data cleaning and analysis. Results From 2013 to 2016, a total of 16206 imported cases of infectious diseases were reported in China. Of all the cases, 83.12%(13471 cases) were malaria cases, followed by dengue fever (2628 cases,16.22%). The majority of the imported cases were males (14522 cases, 89.61%). Most cases were aged 20-50 years. Except Zika virus disease and yellow fever, which were mainly reported before and after spring festival, other imported infectious diseases mainly occurred in summer and autumn. The epidemic in affected provinces varied with the types of infectious diseases, and Yunnan reported the largest case number of imported infectious diseases, followed by Jiangsu, Guangxi and Guangdong. The imported cases were mainly from Asian countries, such as Burma, and African countries, such as Angola, Equatorial Guinea and Ghana, which also varied with the types of infectious diseases. Conclusions We should pay more attention to imported infectious diseases and strengthen the prevention and control measures in our country. In order to reduce the incidence of imported infectious diseases, the health education should be enforced for persons who plan to travel abroad and the active surveillance should be strengthened for returned travelers.

Objective: To explore the efficacy of tenofovir disoproxil and adefovir dipivoxil treatment in patients with hepatitis B virus e antigen (HBeAg) negative was analyzed through the comparison of highly sensitive HBV viral load monitoring with HBV genotyping and drug resistance mutations. Methods: The clinical data of newly diagnosed chronic hepatitis B patients from January 2015 to June 2017 in outpatients and inpatients were randomly divided into tenofovir and adefovir group. Quantitative detection of HBV DNA levels before therapy and at 12, 24, 48, 96, and 120 weeks after therapy were determined for HBV genotypes and drug-resistant mutations in HBeAg-negative patients. Student’s t-test was used to compare the measurement data between groups. The data of comparison between groups were tested by χ ². Results: A total of 106 cases of HBeAg-negative patients were collected. Tenofovir disoproxil had a higher rate of HBV DNA suppression (54%) than adefovir dipivoxil treatment (42%), but the difference was not statistically significant (P = 0.19). After 120 weeks of treatment, a total of 46 patients (93.9%) were enrolled in the tenofovir disoproxil group with HBV DNA quantitation < 2 000 IU / ml. Adefovir dipivoxil group of patients with HBV DNA < 2 000 IU / ml a total of 40 cases, accounting for 75.5%. The difference between the two groups was statistically significant (P < 0.05). For 49 cases of HBeAg-negative patients, HBV B, C, B and C were mixed before tenofovir dipivoxil treatment, and C1653T, A1762T and G1764A mutation sites were detected in patients with D genotype. Patients C, B, C, B, and C were examined for C1673T, G1896, G1858, G1899A. After treatment, the detection rate of the above mutation sites decreased, but C1653T, C1673T and G1899A were not detected. New mutation sites such as G1915A / C, L180M, M204V, V207I / L, T184A and V173L were detected, Low resistance rate (25%). Conclusion Tenofovir disoproxil can be recommended as a treatment for HBeAg-negative patients. For HBeAg-negative patients, the choice of high-sensitivity detection of HBV DNA levels, better monitoring of anti-HBV efficacy.
