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.

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.

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 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 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 sum up the experience of performing a laparoscope-assisted hemiorrhaphy for huge ventral hernia through small incision.Methods Clinical data were retrospectively analyzed for 18 cases of huge ventral hernia admitted from Jan 2009 to Sept 2009 undergoing laparoscope- assisted hernia mpair through small incision.Data renewed including the operational duration,missed hernia,length of the incision,serumal cyst,the length of hospital stay,chronic pain and the recidivation.Results Surgery was successful in all of the 18 cases,the operational time was(129±19) main,the length of the incision was(5.6±1.0) cm.Missed hemia were identified in 3 cases during the operation.One case:suffered from postoperative serumal cyst,the postoperative length of hospital stay was(5.1±1.2) days,postoperative incisional pain lasting for more than 3 months was identified in 1 case,there was no incisional infection and nor injury to intraabdominal organs,there was no operative mortahty,all the cases were followed-up for(8.6 ±1.6)months and there was no recidivation.Conclusions The laparoscope hemia repair with the subsidiary of micro-incision is effective and safe,and it reshapes the abdominal wall.

Objective Evaluating the effect of situational questions for qualifying the students'abilities in physiolo-gy examination .Methods Comparing the difficulty coefficients and discrimination indexes between situational and traditional choice questions .Results Compared with the traditional choice questions , the difficulty coefficient of situational questions increased , while the discrimination indexes were more reasonable .The discrimination indexes of situational understanding questions were higher than those of the traditional memory and understanding questions . There were no difference between discrimination indexes of the situational application questions and those of tradi -tional application questions .Conclusions Situational questions not only improved the quality of examinations , but also facilitate evaluating students'learning ability .
