Objective To evaluate efficacy and safety of glucocorticoids for community-acquired pneumonia (CAP).Methods We searched relevant randomized controlled trials (RCT) from Pubmed,EMBASE,Cochrane Library,Chinese Journal Full-text Database,Chinese Biomedical Literature Database and traced the related reference to obtain the information that had not been found by using key words of steroids,glucocorticoids,cortisol,corticosteroids,community acquired pneumonia and CAP.The quality of RCT included was evaluated.Meta-analysis was performed with RevMan 5.0 provided by the Cochrance Collaboration.Results Seven RCTs involving 944 patients were included in the meta-analysis.Mean length of hospital stay in glucocorticoids treatment group was significant shorter than that in conventional treatment group (WMD =-1.70,95％ CI:-2.01-1.39,Z =10.81,P ＜0.01).No significant differences were found regarding mortality (RR =0.77,95％ CI 0.46-1.27,Z =1.03,P =0.30),mean length of ICU stay (WMD =1.17,95％ CI:-1.68-4.02,Z =0.81,P =0.42),the risk of double infection (RR =1.32,95％ CI 0.66-2.63,Z=0.79,P=0.43),the incidence of hyperglycemia (RR=1.84,95％ CI0.76-4.41,,Z=1.36,P=0.17),the incidence of upper gastrointestinal bleeding (RR =1.98,95％ CI O.37-10.59,Z =0.80,P =0.42) between conventional treatment group and glucocorticoids treatment group.Conclusions Glucocorticoids treatment used in patients with community-acquired pneumonia may shorten the course of illness and possess better safety,but could not reduce the mortality.

Objective To study the effect of baicalin on the expression of receptor activator of nuclear factor-?B ligand (RANKL) and osteoprotegerin (OPG) in cultured human periodontal ligament cells (HPDL cells) as well as its action mechanism. Methods We first constructed small interferring RNA (siRNA) eukaryotic expression vector targeted transforming growth factor ?Ⅱ receptor (TGF-?RⅡ),and then transfected it into T cells. Then HPDL cells together with T cells transfected with siRNA or not were placed in medium that had been added with lipopolysaccharide (LPS) and baicalin. They were divided into six groups and cultured for 48 hours. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to observe the effect of baicalin on OPG-RANKL expression in HPDL cells. Results The clone sequence correctly identified by RT-PCR was consistent with the designed target sequence. The recombinant vector was constructed successfully and the expression of TGF-?ⅡR of T cells which had been transfected with siRNA1 was inhibited obviously. Ratio of RANKL/OPG in each group differed significantly (P

Objective To explore the therapeutic value of bronchoscopy in pediatric status asthmaticus.Methods A total of 16 children with status asthmaticus received standard medical therapies (therapy group) from January 2008 to August 2010 in pediatric intensive care unit (PICU) at First Hospital,Xiamen University.However,l0 of them underwent fiberoptic bronchoscopy and bronchoalveolar lavage (BAL) (bronchoscopy group) along with standard medical therapies from September 2010 to July 2012.The values of oxygenation index (PaO2/FiO2),arterial partial pressure of carbon dioxide (PaCO2),blood oxygen saturation (SaO2),heart rate (HR),respiratory rate (RR) within 1 hour before bronchoscopy procedure,within 6 hour post procedure and within 24 hour post procedure were observed.The extinction time of wheezing sound,PICU length of stay and admission length of stay were observed between therapy and bronchoscopy groups.Results Bronchoscopies revealed a lot of thick mucus plugs and secretions.Large airways were lavaged for clearance of obstructive secretions with normal saline.Within BAL fluid counts of the bronchoscopy group,there were neutrophilia (n =8),eosinophilia (n =4) and neutrophilia/ eosinophilia (n =3).Within BAL fluid cultivation of the bronchoscopy group,4 patients had positive results for Streptococcus pneumoniae (n =2),Pseudomonas aeruginosa (n =1) and Staphylococcus aureus (n =1).In bronchoscopy group,the values of PaO/FiO2,PaCO2,SaO2,HR and RR were 319 ± 19,(40 ±4) mm Hg(1 mm Hg =0.133 kPa),(92.6 ± 1.5) ％,(128 ± 12) rates/min and (35 ± 4) breaths/min within 6 hour post procedure versus 255 ± 24,(54 ± 5) mm Hg,(89.2 ± 2.6) ％,(148 ± 10) rates/min and(50 ± 6)breaths/min within I hour before procedure (P ＜ 0.01).At 24 hour post procedure,the values of PaO2/FiO2,PaCO2,SaO2,HR,RR for bronchoscopy group were 354 ± 21,(40 ± 3) mm Hg,(93.4 ±1.1)％,(125±9)rates/min and(34 ±3)breaths/min versus 317 ±21,(46 ±4)mm Hg,(90.1±2.5) ％,(138 ± 8) rates/min and (43 ± 3) breaths/min respectively for therapy group (P ＜ 0.01).The extinction time of wheezing sound was (67 ± 22) hours for bronchoscopy group vs.(98 ± 23) hours for therapy group(P ＜ 0.01).The mean PICU length of stay was (1.6 ± 0.7) days for bronchoscopy group vs.(2.6 ± 0.7) days for therapy group (P ＜ 0.01).The mean admission length of stay was (5.0 ± 0.7) days for bronchoscopy group vs.(6.6 ± 1.2) days for therapy group(P ＜ 0.01).All patients for bronchoscopy group tolerated the procedure without any complications.Conclusion As a safe adjunctive therapy in pediatric status asthmaticus,flexible bronchoscopy with bronchial lavage may reduce the admission and PICU length of stay and alleviate clinical symptoms.

Objective To investigate the production of IL-17,IL-4 and IFN-γ in sputum of pediatric patients with asthma.Methods 61 pediatric patients with asthma in stage of exacerbation were enrolled as exacerbation group.and these patients in remission stage after therapy were enrolled as remission group, and 45 healthy children were chose as control group.The percentage of neutrophils and eosinophils were counted in regular way with sputum pigmentation,and the level of IL-17,IL-4 and IFN-γ were detected by enzyme-linked immunosorbent assay.Results IL-17 in exacerbation group Was highest among three groups, and IL-17 in remission group was higher than that in control group.In exacerbation group,IL-4 was higher and IFN-γ was lower than those in other two groups,and no significant difference Was found between remission group and control group.While in exacerbation stage,IL-17 was positive correlated with IL-4,and IFN-γ was negative correlated with IL-17 and IL-4.Conclusions IL-17 and IL-4 are related to the occurrence and exasperating of asthma,and IL-17 is suit for indicating the inflammation of asthma.IFN-γ is a protective factor of asthma.

Objective To summarize the experience of nursing cancer patients with Wernicke encephalopathy (WE) after gastrointestinal surgery. Method The clinical data of 6 patients with WE after gastrointestinal surgery in our hospital from January 2005 to June 2015 were retrospectively analyzed to summarize the nursing strategies. Results All the 6 patients showed mental changes of different types, 5 patients developed with ocular manifestations and one patient with ataxia. Only one patient showed the classic triad of the disease at clinical presentation. All the 6 patients had characteristic manifestations on cranial MRI and received thiamine (vitamin B1) at diagnosis. Four patients were completely recovered and 2 were partially recovered. Conclusion Timely sufficient thiamine supplementation during the perioperative period is the key to prevent and treat WE in the patients with gastrointestinal cancer. Careful observation of the patients′ mental state and the effective nursing for the special classic triad of the disease are critical for a better prognosis.
