Objective To investigate the in vitro effects of various antibiotics (spectinomycin, ceftriaxone, erythromycin, ofloxacin and doxycycline) against 12 isolates of C. trachomatis. Methods Minimal inhibitory concentrations (MICs ) and fractional inhibitory concentrations (FICs) of the antimicrobials against all C. trachomatis were calculated. Checkerboard method was used for the determination of FICs and Ridit test for the comparison of the interactions among the various combinations. Results No difference was observed in most of the combinations. No antagonism was found in all except for ceftriaxone-doxycycline combination. Synergism was observed in 42% (5 of 12) and 50% (6 of 12) of the chlamydial isolates for erythromycin-spectinomycin and doxycycline-spectinomycin combination, respectively. No significant difference was observed among triple combinations with spectinomycin or with ceftriaxone. When interactions of erythromycin, ofloxacin and doxycycline with spectinomycin were compared to those with ceftriaxone respectively, both interactions of erythromycin (U = 2.46, P = 0.014) and doxycycline (U = 2.83, P = 0.002) were more synergistic with spectinomycin than those with ceftriaxone. Conclusions This study indicates that the combination of spectinomycin with erythromycin or doxycycline is more effective against C. trachomatis than that of ceftriaxone. Therefore, spectinomycin rather than ceftriaxone might be recommended in the dual therapy against C. trachomatis and N. gonorrhoeae.

Objective To quantitatively analyze the early warning value of laboratory indexes for death risk in children with criti ‐cal hand foot and mouth disease (HFMD) .Methods The univariate and multivariate Logistic regression analysis were conducted to explore the independent risk factors of death in critical HFMD children .Then the area under receiver operating characteristic curve (AUC) was applied to give the comprehensive assessment of the test model ,as well as the early warning capacity and the optimal cut‐off level of laboratory indexes in critical HFMD children .Results The AUC of the Logistic regression model (Y ) established based on white blood cell ,neutrophil ,myoglobin ,creatinine for early predicting the death risk in critical HFMD children patients was 0 .847 (95% CI :0 .783 - 0 .911) ,which indicating that its diagnostic value was superior to single index .Conclusion The diag‐nostic value of the Y model established based on four indexes of white blood cell count ,neutrophile granulocytes count ,myohemo‐globin and creatinine is superior to any single index ,which has the better early warning value for the death risk in children with crit‐ical HFMD .

Objective To investigate the impact of severity of psoriasis on quality of life in patients with psoriasis vulgaris.Methods A questionnaire interview was carried out to the outpatients with psoriasis vulgaris(n=504)from Dec.2000to Sept.2001.All the patients were more than18years old.The content of questionnaire included daily life and activities,work and school performance,social activities and personal relationships,and psychologic status.Disease severity was assessed with psoriasis area and severity index(PASI).498patients were included for the final analysis.Statistical analysis was performed with SPSS software package.Results63.3%patients were restricted in their food selection.40.2%had bad sleep,59.0%could not dress short clothes in the summer.26.5%were restricted in use of public traffic and services.15.1%were rejected in haircut and cosmetic service.31.2%had decreased income along with severity of the disease.58.8%felt uncomfortable in social activities and public places.25.8%avoided handshaking with others.43.3%were reluctant in social intercourse.29.0%were not willing to take part in social activities,especially for moderate and severe cases.54.9%felt that their self-esteem was injured.26.6%thought that other peoples always avoided to meet them.64.4%felt anxiety for their disease.83.1%often worried about relapse or exacerbation of psoriasis.15.9%showed a tendency to commit suicide.Conclusions The more severe the disease is the more impact it may have on the daily life,work and school performance,social activities and personal relationship,and psychologic status in patients with psoriasis vulgaris.It is reccommended that besides the conventional treatment bio-psychic and social medical management be given to the patients especially for moderate and severe cases.

Objective To explore the genetic variation in children patients with esophageal atresia (EA ) to provide a prophase basis for further studying EA pathogenesis .Methods Ten children cases of EA were collected from the neonatal surgery department of our hospital .The high-throughput whole-exon sequencing was used to study the genetic variations ,and their clinical significance was analyzed by the bioinformatics methods .Results In the high quality sequencing data ,the effective clean reads accounted for 85 .36% ,in which 97% of the clean reads could participate in the comparison with the reference genes .The comparison analysis obtained 520541 single nucleotide polymorphism sites ,in which single nucleotide variation(SNV) occurred at 149622 sites ,including synonymous mutation ,nonsynonymous mutation ,stop codon gain ,stop codon loss ,frameshift insertion ,nonframeshift insertion ,unknown mutation ;meanwhile ,598 copy number variation genes were detected .The functional cluster analysis revealed that the mutant genes were closely related to cell biology .Conclusion The SNV occurrence may influence the expression and function of body various proteins and may play an important role in EA pathogenesis .
