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 investigate the clinical and imaging features of Foot-Yangming meridian-muscle syndrome of knee osteoarthritis(KOA) so as to promote the normalization and standardization of the meridian-muscle therapies. Methods A total of 31 KOA cases (involving 31 knees) of Foot-Yangming meridian-muscle syndrome were included into the study group , and 31 healthy volunteers (involving 31 knees) served as the control group. A retrospective research of patellofemoral relationship was carried out based on the clinical and imaging features. Results The differences of Insall index and patella index between the study group and control group were insignificant(P> 0 . 05), but the differences of patellofemoral index , patellofemoral congruence angle, and external patellar angle between the study group and control group were significant(P<0.01). Conclusion The patellofemoral relationship disorder is one of main lesions in Foot-Yangming meridian-muscle syndrome of KOA.

Objective:In order to obtain safer HBV DNA vaccine,recombinant kanamycin resistance eukaryotic expression plasmid containing the gene of HBV surface antigen was constructed and used to study humoral immune response in BALB/c mice.Methods:HBV antigen middle protein(preS2+S) encoding gene fragment was isolated from the recombinant eukaryotic expression plasmid pcDNA-S 2S;subcloned into eukaryotic expression vector pVAX1.After confirmed the presence of the gene by restriction endonuclease analysis,it was used to immunize the healthy BALB/c mice at different doses,and the levels of anti-HBs in serum was determined by ELISA.Results:Restriction endonuclease analysis confirmed recombinant plasmid pVAX-S 2S was what was expected.Serum anti-HBs was detected at the 2nd week after DNA vaccination at all three doses(100 ?g,50 ?g,10 ?g per mice)and their titers were increased with time.Quantitative comparison of the serum anti-HBs levels revealed significant(P

Objective: To study the classification of congenital velopharyngeal insufficiency(CVPⅠ).Methods:30 patients with CVPI were divided into 2 groups.The patients in group I were with submucous cleft palate,those in group Ⅱwere without noticible abnormality.A11 patients received oral examination and 1ateral cephalogram examination. ANS-PNS(1ength of hard palate),PNS-U(velar 1ength),PNS-PPW(pharyngeal depth),SPT(thickness of soft palate),need ratio, elongation and upward angle of soft palate were measured. Results:PNS-U was shorter and PNS-PPW was longer in the patients than in the health controls (P

Objective To analyze the therapeutic effect of the radical operation for gastric cancer in elderly patients and to investigate relevant factors affecting the efficacy Methods 216 cases of elderly patients with gastric cancer were divided into two groups:radical distal-and proximal-gastrectomy group (n=108,each).The therapeutic effect in the near future,intraoperative and postoperative recovery,numbers of lymph nodes resection as well as factors affecting the long-term survival rate were compared between two groups.Results The radical distal-versus proximal-gastrectomy group showed that the mean operation time was (241.8 ± 40.2) min vs.(244.7 ± 39.7)min,blood loss was(299.5 ± 114.9) ml vs.(273.8-± 121.4) ml,the number of lymph node dissection was(28.4± 9.4) vs.(27.7 ± 9.1) particles,the complication rate was[14/108 (13.0％)] vs.[15/108 (14.0 ％)],3-year survival rate was (46.9 ％) vs.(47.5 ％),without statistically significant differences (all P ＞ 0.05).Multiple regression analysis showed that TNM stage (OR =1.536),lymph node metastasis(OR =0.739),cancer infiltration depth (OR =1.534) and chemotherapy regimens (OR =1.337)are risk factors for the postoperative 3-year survival rate.Conclusions Surgical treatment of elderly patients with gastric cancer is significantly effective,TNM stage,lymph node metastasis,depth of invasion,tumor size and the chemotherapy regimens are closely associated with the life quality of patients.

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.

Objective To find out the main target organs, their main pathological changes and to explore the toxic mechanism of the macleaya cordata. Method SD rats were intoxicated by oral administration with extracts of macleaya cordata followed by pathological and electromicroscopic examination of main organs. Results The LD50 was 19.5% when 1.5g/ml macleaya cordata extract was oral administrated. All pocsoned rat's serum GPT, Cr, BUN, CK, CK-MB increased markedly. The EKG were abnormal. The weight of brain, liver, spleen, and kidneys decreased significantly. There were extensive congestion and hemorrhage in heart, brain, liver and kidneys. The mitochondria, endoplasmic reticulum and nuclear membrane of the rat's heart, brain, liver, and kidney were destroyed. Conclusion The results indicated that the toxic target organs of macleaya cordata were the heart, brain, liver and kidneys mainly. The toxic mechanism of macleaya cordata poisoning was the damage of the mitochondrial, endoplasmic reticulum and nuclear membrane directly causd by the macleaya cordata.
