Objective To investigate the value of PCT in the diagnosis of severe infection in children.Methods The clinical data of patients with infectious diseases treated in our hospital from December 2013 to February 2016 were retrospectively analyzed.According to the degree of infection,the patients were divided into local infection group and severe infection group,At the same time,the clinical data of 50 children with non infectious diseases were selected as control group.The differences of serum PCT and cytokine levels were observed between the three groups,at the same time,according to the prognosis of patients with severe infection group were divided into improvement group and deterioration group,The differences of serum PCT and inflammatory cytokines levels in the patients with severe infection in the improvement group and the worsening group,Analysis of the correlation between PCT levels and serum inflammatory cytokines levels in children with severe.Results There were significant differences in the levels of PCT,IL-18,IL-6 and hs-CRP between the three groups,which were from high to low: severe infection group,local infection group and control group; Deterioration of PCT,IL-18,IL-6,hs-CRP and levels were higher than the improvement group(t=-10.099,-8.949,-10.827,-2.088,P<0.05); The level of PCT were positively correlated with IL-18,IL-6 and hs-CRP levels in children with severe infection(r=0.385,0.412,0.408,P=0.012,0.008,0.017).Conclusion PCT has a good diagnostic value in children with severe infection,and it is closely related with the level of inflammatory cytokines in children with severe infection.

Objective To study the present situation of legionella pneumophila(Lp) infection of low respiratory tract infection in children less than 5 years old.Methods Three hundred hospitalized patients with the diagnosis of low respiratory tract infection were enrolled in the study,191 males,109 females,aged 27 d to 5 years old,course from 1 d to 6 months.Serum antibody(IgM,IgG) of Lp serogroup 1-7 was detected by enzyme-linked immunosorbent assay(ELISA).Results In the patients,17 cases were positive,and the positive rate was 5.67%.Of the 17 children,the males(n=11) and females(n=6) did not significantly influence the positive rate(5.76% vs 5.50%).Four of them were between 27 days and 1 year old;7 were 1 to 3 years old,6 were 3 to 5 years old.The positive rates were significantly different among the 3 groups(2.53% vs 7.37% vs 12.77%) and tendentially increased following the increase of age(?2=7.8164 P

In order to show the social situation and public opinions for the decision-makers of medical reform, the viewpoints of main media, NPC and PCC members, and Internet users were analyzed according to the real-time monitoring data of public opinions on health-related topics ( new rural cooperative medical system, basic public health service, and rural medical workers) during the NPC and PCC, which showed the public awareness of health reform in grass-roots units of China.

OBJECTIVE To analyze infection state and drug resistance feature of Staphylococcus spp with a view of offering references for controlling and treating infection led by it.METHODS Totally 652 strains of Staphylococcus isolated from patients with infection were identified and their drug resistance was analyzed.RESULTS From them 204 strains were Staphylococcus aureus and 448 strains were coagulase negative Staphylococcus detected and the isolating rate of MRSA and MRCNS were respectively accounted for 55.4% and 84.6%.The most common coagulase negative Staphylococcus strains were S.haemolyticus and S.epidermidis.The drug-resistant rates of MRS were higher transparently than MSS.CONCLUSIONS Staphylococcus are one of the main pathogens leading to nosocomial infections.As a result, it is very important to use antibiotics properly for infection control and nosocomial infection management.

Objective To explore the role of CD4+CD25+CD127low/-regulatory T cells (Tregs) in the pathogenesis of psoriasis vulgaris(PV). Methods Flow cytometry analysis was used to detect the amount of Tregs in peripheral blood and ELISA to test the levels of IL-10 and TGF-β1 in blood serum; the suppressive function of Tregs on autologous CD4+CD25-T cells was determined by MTT method. Results No significant difference was found in the proportion of Tregs in PV patients and healthy controls(P>0.05). There was a diminished suppression of Tregs from patients on autologous CD4+CD25- responder T cell proliferation in PV patients when compared with that in controls (P < 0.01). The serum level of IL-10 in patients was lower than that in controls (P < 0.01) while that of TGF-β1 in PV patients was significantly higher than that in controls(P < 0.01). Conclusion Abnormal function of Tregs and low secretion of IL-10 in PV patients might be related to the pathogenesis of psoriasis.

This study aimed to elucidate the effects of different soil water contents on the yield and quality of R.glutinosa.Different soil water contents were adjusted in different periods of growth of R.glutinosa.The yield,content of water extract,catalpol,verbascoside and polysaccharide were determined and analysed by the grey pattern recognition after harvests.The impacts of soil water content from the most important to the least important were medium moisture content (M2),high moisture content (M3),low moisture content (M1) and blank (M4).In the cultivation of R.glutinosa,the soil water content should be remained in the range of 40％-50％ at seedling stage,while 50％-60％ at the stage of root formation and tuber enlargement,and 20％-30％ during harvesting,which can significantly improve the yield and quality of R.glutinosa.

Objective To evaluate preperitoneal tension-free herniorrhaphy for incarcerated and (or) strangulated inguinal hernia.Methods During Mar,2008 to Mar,2015,89 incarcerated and (or)strangulated hernia patients(incarcerated hernia group) and 1 741 primary inguinal hernia patients (elective group) underwent preperitoneal tension-free herniorrhaphy.Results The operation time (42 ± 8 min),length of stay (4.0 ± 2.6 d) and the time return to work (9.0 ± 3.3 d) in incarcerated hernia group were longer than in elective group of (38 ± 4 min),(3.0 ± 0.6 d) and (8.1 ± 2.5 d),respectively (all P ＜0.01).Blood loss [(10 ± 14 ml) vs (7 ±4 ml)] was compareble,P =0.148.There were 1 infection case and 20 seroma cases (22.5％) vs 5 infection cases and 187 seroma cases (12.7％) all P ＞0.05.Followup found hernia recurrence in one case in elective group.Conclusion Preperitoneal tension-free herniorrhaphy is safe and effective for the treatment of incarcerated and(or) strangulated hernia.

Objective To evaluate US, CT and 99mTc-MIBI in the localization of hyperfunctioning parathyroid tumors. Methods Among the 47 patients with primary hyperparathyroidism 45 underwent ultrasound, 47 did CT scan and 36 did double phase imagings.
