Objective To study the early diagnostic predictors and key follow-up parameters for girls with rapidly progressive central precocious puberty (RP-CPP). Methods A total of 260 girls with CPP participated in a prospective, nonrandomized, multi-center, nested case control study. After follow-up six months without any therapy, 114 girls were divided into RP-CPP (n=70) and slowly progressive CPP (SP-CPP) (n=44) groups. Results The basal serum LH and insulin-like growth factor Ⅰstandard deviation score (IGF-ⅠSDS) were the important risk factors of RP-CPP (OR 4.04, 1.578), especially the former. The receiver operating characteristic (ROC) curve revealed that the areas under the ROC curve of basal LH and IGF-ⅠSDS were 0.83 and 0.807, respectively. The levels of basal LH and IGF-ⅠSDS were at 0.52 mIU/ml and 0.35 respectively for the accuracy diagnosis of RP-CPP with the maximum Youden indexs. After follow-up for six months, the change levels of height, breast stages, bone age/chronological age ratio, serum LH, uterine and ovarian volume in RP-CPP group were significantly higher than those in SP-CPP group (all P<0.05). Conclusions The level of basal serum LH and IGF-ⅠSDS may be used as the risk predictors for early diagnosis for girls with RP-CPP. The change levels of basal LH, progress rates of gonad and sex character, height, and impaired growth potential seem to be the key follow-up parameters for CPP progress.

Objective To analyze the willingness and influencing factors for usage of pre-exposure prophylaxis(PrEP) among male students who have sex with men (MSM) in universities of Guangxi. Meth-ods 295 MSM students in universities were recruited by Snow-balling methods. Questionnaires were self-administered to collect social demographic information,AIDS related risky sexual behaviors and willingness for usage of PrEP. Logistic regression was employed for univariate and multivariate analysis. Results Of the 295 MSM,58(19.7%)had ever heard PrEP,265(89.8%) said that they would like to use PrEP. Multivari-ate logistic regression analysis showed that those who had found partners through friends ( OR=11.419,95%CI:1.363~95.641), those who would advise his friend to use PrEP ( OR=87.946,95%CI:13.660-566. 222),those who concerned the convenience to gain the medicine ( OR=119.652,95%CI:3.765-3802.184) and those who said that they could take medicine every day ( OR=88.245,95%CI:10.237-760.696) were more likely to accept PrEP. The subjects whose partners would be angry if they stick to use condoms( OR=0.106,95%CI:0.019-0.606),and those who suspected the effectiveness of drugs( OR=0.010,95%CI:0. 001-0.112) were less likely to accept PrEP. Conclusion The acceptability of PrEP is high in university students'MSM. The safety of drugs and the convenience to gain the medicine are the main influencing factors for usage of PrEP.Using of PrEP should be strengthened to the MSM.

Objective:
To analyze serum HBV-RNA levels in patients with chronic hepatitis B whose serum HBV-DNA has dropped to undetected levels after treatment with entecavir, and to explore the correlation between HBV-RNA level and liver biochemical parameters, which lay the research foundation for the clinical significance of new serological marker HBV-RNA.
Methods:
HBeAg negatively detected 107 cases with chronic hepatitis B whose serum HBV-DNA test results were lower than detection level for six consecutive months after receiving standard nucleoside therapy for more than 12 months were included. HBV-RNA level was detected by Perkin-Elmer reagent. HBV-DNA level was detected by Roche Cobas. Hitachi automatic biochemical analyzer was used to detect ALT and AST. Architect chemiluminescence analyzer was used to detect HBsAg, HBeAg, anti-HBe and anti-HBc. RStudio software was performed to analyze the correlation between HBV-RNA level and liver biochemical parameters. Logistic regression was used to analyze the independent factors influencing HBV-RNA level.
Results:
The positive detection rate of serum HBV-RNA in patients with chronic hepatitis B whose serum HBV-DNA had dropped to undetected levels after ETV treatment was 22.43%. HBsAg, ALT and AST levels in HBV-RNA positive group were slightly higher than HBV-RNA negative group, while anti-HBc levels were slightly higher in HBV-RNA negative group. There was no difference in the level of anti-HBe between the HBV-RNA negative and the positive group. Logistic regression analysis showed that anti-HBc was an independent factor influencing the level of HBV-RNA detection (

Objective To investigate the clinical characteristics of upper respiratory tract infection in hospita-lized children with mental disorders,and to analyze the risk factors for nosocomial infection,so as to provide reference for clinical treatment and prevention and control of nosocomial infection(NI). Methods The NI of 1 587 hospitalized children at the Second Affiliated Hospital of xinxiang Medical University from January to December 2016 was investiga-ted and a retrospective study was conducted on 78 hospitalized children with nosocomial upper respiratory tract infec-tion. In a ratio of 1: 2,the patients with mental disorders during the same time at hospital,without the occurrence of hospital infection,with same gender and same age group,were selected as the control group,then the univariate regres-sion analysis and multivariate conditional Logistic regression analysis were carried out. Results Of the 1 587 cases,86 cases were NI,and the incidence of NI infection was 5. 42%. Among them,the upper respiratory tract infection accoun-ted for 83. 87%(78 cases). Univariate conditional Logistic regression analysis indicated that the type of disease,hospi-talization days,insight,rehabilitation activities,hand hygiene habits,self -support ability,eating habits,management mode,seasonal and environmental conditions were the risk factors for upper respiratory tract infection in hospitalized children with mental disorders(all P<0. 05). Multivariate analysis showed that the odds ratio( OR)of autumn and winter,poor self-support ability,no insight,poor hand hygiene habits,longer hospitalization days( over 14 d),severe mental illness were 19. 627( 5. 391 -23. 518 ),12. 835( 3. 436 -18. 715 ),5. 427( 1. 879 -16. 921 ),3. 752 (1. 743-16. 864),3. 618( 1. 659 -12. 671 ),3. 361( 1. 478 -10. 527 ),respectively,which were significantly associated with the occurrence of upper respiratory infection,and the differences were statistically significant( all P<0. 05). Conclusions The season,self-support ability,insight,hand hygiene habits,days hospitalization,and disease type are the independent risk factors for upper respiratory infection in hospitalized children with mental disorders,posi-tively controlling and eliminating of independent risk factors for upper respiratory tract may reduce its incidence in the inpationt children.

OBJECTIVETo assess the methodological quality and reporting quality on Meta-analysis being published in the Chinese Journal of Gastrointestinal Surgery.
METHODSComputerized literature searching was carried out in Wanfang Medical Online to collect articles that Meta-analysis was used in the Chinese Journal of Gastrointestinal Surgery since it was founded till July, 2014. Manual retrieval was also conducted. Two researchers independently screened for literature and extracted data. Qualities on methodologies or on the processes of reporting and reviewing were evaluated by both AMSTAR and PRISMA scales.
RESULTSForty-two papers on meta-analyses were included in this study. Results on the quality of methodology evaluation showed that the lowest and highest scores were 6 and 9 respectively, the median score was 7. Two articles (4.8%) were rated as high, 40 articles (95.2%) as moderate and 0 articles (0%) as low. Although the quality of methodology was above the average, however, there were still some problems seen in some papers as the conflict of interest was not stated, the list of studies (included and excluded) was not provided, a comprehensive literature search was not performed, the likelihood of publication bias was not assessed, etc. Results on the quality of reporting evaluation showed that the lowest and highest scores were 14 and 22 respectively, the average score was 18.43 ± 2.03, 3 articles (7.1%) scored less than 15 points, 35 articles (83.3%) scored 15.5-21 points, and 4 articles (9.6%) scored 21.5-27 points. The included reviews had high quality on the titles of the report, inclusion criteria, rationale of introduction, synthesis of results, results of individual. However, the abstract, objectives of introduction, scheme and registered, inclusion criteria, research screening, additional analysis, conclusion limitations, funding support etc. were lack of comprehensive reports.
CONCLUSIONSArticles on Meta-analysis published in the Chinese Journal of Gastrointestinal Surgery are of high quality. The Chinese Journal of Gastrointestinal Surgery can provide better evidence for clinical decision to gastrointestinal surgeons. However, both of qualities on methodology and reports sill call for continuous improvement.

Objective:Based on UPLC-Q-TOF/MS, to screen a panel of plasma metabolite biomarkers for TB diagnosis and evaluate its diagnostic efficacy.Methods:102 active TB patients [49 males, 53 females, age 40.0(24.0, 48.5) years] from Shanghai Pulmonary Hospital and Shanghai East Hospital from January 2017 to January 2018, 100 TB-IGRA positive patients [55 males, 45 females, age 44.0(37.0, 52.0) years] and 96 healthy controls [55 males, 41 females, age 43.0(32.2, 52.8) years] from Shanghai East Hospital were randomly enrolled. UPLC-Q-TOF/MS technology was used to detect small molecule metabolites in plasma. Combined with multivariate statistical methods VIP and univariate statistic analysis Student's t-test, the main differential metabolites in the plasma of patients with active tuberculosis were filtered. The ROC curve was analyzed for the differential metabolites, and the AUC value, specificity, and sensitivity for diagnosis were used to screen metabolic biomarkers with diagnostic potential. Results:All the samples examined resulted in 10 266 variables, and 1 153 substances were identified by qualitative retrieval through the human metabolome database. After pairwise comparison of samples from the three groups, differential metabolites that simultaneously satisfied VIP > 1 and P<0.05 were plotted into a Venn diagram, and the resulting intersection set contained 38 major differential metabolites. The ROC curve analysis of 38 major metabolites showed that the area under the curve of lactic acid, dopamine, 9-pentadecenoic acid, and 12,13-dihydroxy octadecadienoic acid in the diagnosis of active tuberculosis were 0.92, 0.98, 0.94, and 0.94, respectively, the specificity was both more than 90% and the sensitivity was both more than 80%. The specificity and sensitivity of four metabolites in the combined diagnosis of active tuberculosis were both 94%. Conclusion:Lactic acid, dopamine, 9-pentadecenoic acid, and 12, 13-dihydroxy octadecadienoic acid can be used as potential metabolic biomarkers for tuberculosis diagnosis.
