ObjectiveTo explore the diagnosis and treatment of incomplete Kawasaki disease.MethodsA retrospective analysis was applied in 39 children patients clinically diagnosed as Kawasaki disease.ResultsThirtynine cases were found to have a high temperature over 5 days( 100％ ),30 patients with bilateral conjunctival congestion (76.9％),28 cases with cherry pink and chapped lips( 71.8％ ),21 patients with erythema multiforme and erythra(53.8％ ),20 cases with hand-foot scleredema(51.3％ )and 10 patients with cervical lymphatic enlargement (25.6％).In addition to the high temperature,22 cases were found to have three classic clinical diagnostic characterstics(56.4％ ),and 17 patients with two classic characterstics(43.6％ ).During the course of disease,C-reactve protein was observed to increase,and erythrocyte sedimentation rate speed up significantly.Intravenous infusion of gamma globulin and oral administration of aspirin was confirmed to be effective for incomplete Kawasaki disease.ConclusionThe careful observation and complete clinical examination was conducive to early diagnosis of incomplete Kawasaki disease instead of misjudge and missed diagnosis.

Objective To explore clinical features and drug sensitivity of Streptococcus pneumoniae (SP) isolated from pediatric patients with lower respiratory tract infection, and to provide evidence for clinical use of antibiotics. Methods A total of 6 358 clinical SP isolates from children with lower respiratory tract infection from January 2008 to December 2012 were col-lected and retrospectively analyzed. The antibiotic sensitivity was done by Kirby-Bauer method and E-test, and all results were in strict accordance with the rules of CLSI. Results The isolated SP strains were mainly from different departments of pediatrics. All clinical cases with SP infection mainly included pneumonia and bronchitis. The resistance rates of 6 358 SP strains to penicil-lin, cefotaxime, erythromycin, clindamycin, cotrimoxazole, tetracycline, chloramphenicol, levolfoxacin, vancomycin were 5.0%, 12.9%, 98.7%, 96.0%, 92.2%, 7.3%, 5.6%, 0.2%and 0.0%respectively, and the resistance rate to penicillin and cefotaxime was signiifcantly different in every years (all P<0.05). The resistance rates of the 318 penicillin-resistant SP strains to the above anti-biotics were 100.0%, 42.6%, 100.0%, 100.0%, 99.2%, 23.6%, 6.8%, 0.6%, 0.0%respectively, and the resistance rate to penicillin and cefotaxime was signiifcantly different (P=0.001). Conclusions The antibiotic resistance rates of SP strains isolated from children with lower respiratory tract infection were higher to erythromycin, clindamycin, cotrimoxazole and tetracycline, and an increasing rate in drug resistance to cefotaxime was observed in recent years. Appropriate antibiotics should be selected for the treatment of infection according to drug sensitivity.

Objective To analyze the changes of celluar and humoral immunity in children with juvenile idiopathic arthritis(JIA),as well as the changes in different subtypes,and to investigate the role of cellular and humoral immunity in the pathogenesis of JIA.Methods Ninety-two JIA subjects and 82 controls(healthy children) were included into this study.The levels of T lymphocyte subsets,natural killer (NK)cells,and B cells were analyzed by using flow cytometry.The serum interleukin-1 (IL-1),tumor necrosis factor-α (TNF-α),interleukin-l0 (IL-10),transforming growth factor-β(TGF-β) levels were detected by using enzyme-linked imnmunosorbent assay (ELISA).The serum IgG,IgM,IgA and C3,C4 levels were detected by using velocity scatter turbidimetry.Independent t-test,One-Way ANOVA test and Pearson analysis were adopted for data analysis.Results 1.In the group of JIA,the levels of CD3,CD4,IL-1,TNF-α,IgG,IgM,IgA and C3 were higher than those in the control group(all P ＜ 0.05),while the levels of CD4CD25,CD8,NK cells,IL-10 and TGF-β were lower than those in the control group(all P ＜0.05),and the ratio of CD4/CD8 was higher than that in the control group (P ＜ 0.05).2.In the group of systemic-onset JIA (so-JIA),the levels of CD4,IL-1,TGF-β,IgG,IgM,IgA,C3 and the ratio of CD4/CD8 were higher than those in the oligoarthritis JIA group(all P ＜ 0.05),while the levels of CD4CD25,CD8,IL-10 were lower than those in the oligoarthritis JIA group(all P ＜ 0.05).In the group of polyarthritis JIA,the levels of IL-1,TNF-α,IgG,IgM and IgA were higher than those in the oligoarthritis JIA group(all P ＜0.05),while the levels of CD4CD25,CD8,IL-10 were lower than those in the oligoarthritis JIA group (all P ＜ 0.05) ; In the group of so-JIA,the levels of CD4,TGF-β,C3 and C4 were higher than those in the polyarthritis JIA group (all P ＜ 0.05).3.The value of IL-1,TNF-α were positively correlated with that of C-reactive protein (CRP),erythrocyte sedimentation rate(ESR) in the JIA group(all P ＜ 0.05),while the value of IL-10,TGF-β was negatively correlated with that of CRP,ESR(all P ＜ 0.05).Conclusions There are cellular immunity and humoral immunity disorders in the JIA.Cellular immunity and humoral immunity are all involved in the pathogenesis of JIA.T helper cells are activated and Th1 cytokines increase,suppressive T cells,regulatory T cells impairment and suppressive cytokines decrease but immunoglobin increase,which involve in auto inflammation reaction and articular destruction in JIA.The immunity disturbances are more striking in so-JIA and polyarthritis JIA.IL-1,TNF-α,IL-10 and TGF-β are correlated with the disease activity.

predictive value of combined application of the different obesity measures on incident gallstone diseases model:multi-factor model of male participants was constructed after adding risk factors of age,TC,TG,diabetes,hypertension,smoking,drinking and physical exercise,and-2log L and AIC were 71 257 and 71 275.Then BMI,WC,WHtR,BMI+WC,BMI+WHtR,WC+WHtR and BMI+WC+ WHtR were respectively added into the multi-factor model,and-2log L and AIC were respectively 71 156 and 71 178,71 170 and 71 192,71 197 and 71 219,71 134 and 71 160,71 132 and 71 162,71 170 and 71 196,71 132 and 71 162.The minimal mode of AIC was multi-factor model+BMI+WC,with a difference of 123 compared with multi-factor model of-2log L,showing a statistically significant difference (x2 =123.00,P＜ 0.05).The multi-factor model of female participants was constructed after adding risk factors of age,TC,TG,diabetes,hypertension,smoking,drinking and physical exercise,and-2log L and AIC were 19 612 and 19 630.Then BMI,WC,WHtR,BMI+WC,BMI+WHtR,WC+WHtR and BMI+WC+WHtR were respectively added into the multi-factor model,and-2log L and AIC were respectively 19 568 and 19 590,19 575 and 19 597,19 574 and 19 596,19 558 and 19 584,19 557 and 19 583,19 571 and 19 597,19 556 and 19 586.The minimal mode of AIC was multi-factor model+BMI+WHtR,with a difference of 55 compared with multi-factor model of-2log L,showing a statistically significant difference (x2 =55.00,P＜0.05).Conclusions The increased BMI,WC and WHtR are independent risk factors for incident GD,no matter the gender.In males,the combination of BMI and WC can improved the predictive value of the incident GD,while in females,BMI and WHtR are the best combination for predicting incident GD.
