Objective To assess the efficacy and safety of berberine, amoxicillin, lansoprazole, bismuth quadruple therapy for Helicobacter pylori (H.pylori)eradication.Methods From December 2015 to April 2016,566 patients with initial treatment of H.pylori infection were prospectively enrolled.Patients were divided into observation group (berberine, amoxicillin, lansoprazole, bismuth) and control group (clarithromycin, amoxicillin, lansoprazole, bismuth), 283 cases in each group, and the treatment courses in two groups were both 14 days.Four weeks after completion of the treatment, the eradication rate of H.pylori and adverse effect rate of the two groups were compared.Student t test and Chi square test were performed for comparison between the two groups.Results There was no statistically significant difference in the baseline demographic data including gender,age, body mass index (BMI), symptom score between patients of the two groups (all P>0.05).Four weeks after completion of the treatment, the eradication rates of observation group and control group were 87.5%(244/279) and 87.1%(242/278) according to per-protocol analysis, and which were 86.2%(244/283) and 85.5 %(242/283) according to intention-to-treat analysis.There was no statistically significant difference between the two groups (x2=0.021,0.058;both P>0.05).The adverse effect rates of the two groups were 12.5%(35/279) and 16.5%(46/278), and there was no statistically significant difference (x2=1.795,P=0.180).Conclusions Both the new quadruple regimen containing berberine, amoxicillin and bismuth, and the standard quadruple regimen containing clarithromycin, amoxicillin and bismuth both can effectively eradicate H.pylori infection.The new regimen might be recommended as first-line eradication regimen in Xi′an district or area with high clarithromycin resistance.

Objective To predict the biological process and signaling pathways in which hsa-miR-1908 might be in-volved by a series of bioinformatics analysis, so as to lay foundations and provide theoretical basis for the further studies of hsa-miR-1908 biological function in human preadipocytes. Methods The sequence of hsa-miR-1908 was acquired from miR-Base database, and target genes of hsa-miR-1908 were predicted by miRanda, and then the intersection of the results and the results of gene-chip as gene set were further analyzed by gene ontology and pathway enrichment. Results The hsa-miR-1908 had some conserved property among different species. The functions of the target genes were enriched in Wnt receptor signal-ing pathway through beta-catenin, cell cycle, cell apeptosis and other biological processes. The GnRH signaling, MAPK sig-naling, insulin signaling, cell cycle signal transduction pathways and signaling pathway in pancreatic cancer were signiifcantly enriched. Conclusions The target genes set of hsa-miR-1908 were enriched in multiple biological process which are related with the obesity. This study provides guidance for the further study in human preadipocytes.

Objective To evaluate the effect of labor analgesia on maternal and neonatal outcomes. Methods The medical records of mature puerperas with singleton pregnancy from October 2018 to April 2019 at the General Hospital of Ningxia Medical University were retrospectively reviewed. Puerperas were divided into non-labor analgesia group ( NLA) and labor analgesia group ( LA) according to whether or not puerperas received labor analgesia. Maternal and neonatal outcomes were analyzed. Maternal outcomes in-cluded delivery mode, complications, intrapartum hemorrhage and blood loss at 24 h after birth, duration of the second stage of labor and prolongation, episiotomy and length of hospital stay after birth. Neonatal outcomes included Apgar score at 1, 5 and 10 min after birth, cases of Apgar score＜7 at 5 min after birth, and the proportion and reason of transfer to pediatrics unit. Results A total of 839 puerperas were includ-ed, with 551 cases in NLA group and 288 cases in LA group. Compared with NLA group, the second stage of labor was significantly prolonged ( P＜0. 01) , and no significant change was found in the other maternal or neonatal outcomes in LA group ( P＞0. 05) . Conclusion Labor analgesia can prolong the second stage of labor and exerts no effect on the neonatal outcomes.

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.

Objective: To investigate the association of Internet gaming disorder (IGD) and sleep quality in adolescents of Xi an, thereby providing theoretical evidence for prevention of IGD and improvement of sleep quality of adolescents. Methods: A total of 1 181 adolescents from 3 middle schools of Xi an were randomly selected between August, 2019 and February, 2020. These adolescents were assessed by a series of questionnaires, including basic information questionnaire, IGD and Insomnia Severity Index (ISI). Univariate analysis and multivariate Logistic regression model were used to evaluate the association between IGD and insomnia. Results: Among 929 junior middle school students who participated in online games and the IGD Diagnostic Questionnaire was filled out in the past 12 months, the prevalence of IGD was 20.0%(186). Univariate analyses indicated that gender,whether single family, whether they living with their parents, whether they were addicted to online games, whether they could control the time of online games, and the severity of insomnia influenced IGD ( χ 2=17.11, 8.33, 202.92, 91.23, 29.06, P <0.05). The multivariate Logistic regression of the total population showed that participating in online games was not associated with the severity of insomnia ( OR = 1.62 , 95% CI =0.92-0.85, P >0.05). The people who participated in online games in the past 12 monthsthe severity of insomnia was positively correlated with the risk of IGD ( OR =3.56，95% CI =1.92-6.61, P <0.01). Conclusion Internet gaming disorder become a severe situation in the middle school students. The severity of insomnia might become the risk factor of IGD, so social should pay more attention to the prevention of internet addiction.

Objective To estimate the association between the risk of high birth weight(HBW) and maternal environmental and behavioral factors exposure during pregnancy in rural areas. Methods Data were collected from the surveillance system of birth population and adverse pregnancy outcome in Pingding County, Shanxi Province during 2007 and 2012, where we followed up 204 controls with normal birth weight, 125 cases with HBW≥4 200 g and 171 cases with HBW 4 000-4 200 g. Case control study was performed to explore the potential risk factors of HBW. Results The total number of births was 18 749, including 1 177 cases of high birth weight, with an incidence rate of 6.28% between 2007 and 2012. Concerning the case control study on HBW<4 200 g, after adjusting parental reproductive age and parity, the risk of HBW was 3.10(95% CI：1.67-5.76)times higher among women with gestational weeks ≥42 than that of women with gestational weeks < 42. The risk of HBW in boys was 2.30(95% CI：1.46-3.63)times higher than that in girls. No significant association was observed between maternal BMI before pregnancy and the risk of HBW；Regarding the case control study on HBW≥4200 g, after adjusting maternal reproductive age and parity, the risk of HBW was 3.01(95% CI:1.49-6.08) times higher among women with gestational weeks≥42 than that of those with gestational weeks <42. The risk of HBW was 1.91(95% CI:1.15-3.16)times higher among women with pre-pregnancy BMI≥24 than that of those with pre-pregnancy BMI< 24. The risk of HBW was 2.59(95% CI:1.06-6.32)times higher in women who ate soybean products ≥4 times a week than that of those who ate soybean products less than once a week. Conclusion It would be of public health significance to reduce the risk of high birth weight, which can be reduced by managing pre-pregnancy BMI, diet during pregnancy and controlling gestational week.

Objective To understand the disease spectrum of prehospital emergency patients in Beijing, so as to provide basis for rational allocation of prehospital emergency care resources and for improvement of prehospital emergency care. Methods Emergency dispatch database from 120 dispatching command system of Beijing Emergency Medical Center to was used study the disease spectrum of 120 prehospital emergency patients from 2013 to 2017 in Beijing, and were analyzed the differences of disease spectrum among patients of different years, genders and ages, and the time distribution of different diseases. Results From 2013 to 2017 in Beijing, 1 643 375 patients used 120 prehospital emergency care. The top 3 diseases of the disease spectrum were: injury and poisoning (29.63%), diseases of the circulatory system (18.37%), and diseases of the nervous system (15.80%). The sorting of diseases remained unchanged during the 5 years. The disease spectrums were different among different age groups and gender groups. The calls in spring, summer, autumn and winter accounted for 25.23%, 24.97%, 25.05% and 24.75% respectively. Most calls were made from 08 ∶〗00 to 09 ∶〗59 (12.41%), 12 ∶〗00 to 13 ∶〗59 (10.05%), and 14 ∶〗00 to 15 ∶〗59 (9.91%) during a day. The peak months and hours of different diseases were different. Conclusions The demand for prehospital emergency care has been increasing in Beijing in recent years. It is important to strengthen the prevention of injuries among all ages, especially male, and to improve the prevention and response capacity for acute attack of chronic diseases among older people. Prehospital emergency care resources should be rationally allocated according to the peak months and hours of calls.
