OBJECTIVE To comprehensively analyze the risk factors for infection and colonization of community-acquired MRSA.METHODS The results of 12 studies were analyzed by meta-analysis and the OR value of every factor was calculated.RESULTS All eight risk factors were evaluated:prior hospitalization(OR=2.46,CI1.25-4.85),antibiotics exposure recently(OR=2.77,CI1.34-5.74),contact with healthcare system and medical workers frequently(OR=6.48,CI2.38-17.63),surgery or invasive procedure(OR=2.53,CI1.90-3.36),age(OR=-1.99,CI-9.21-5.23),gender(OR=1.04,CI0.71-1.51),intravenous drug use(OR=1.49,CI0.34-6.54),and underlying diseases(OR=1.12,CI0.55-2.28).CONCLUSIONS Prior hospitalization,antibiotics exposure recently,contact with healthcare system and medical workers frequently and surgery or invasive procedure are risk factors of community-acquired MRSA.The effects of age,gender,intravenous drug use and underlying diseases need further investigation.

Objective To summarize the clinical features and therapy of sarcoidosis in the South of China.Methods A retrospective analysis was perfomed in 31 patients with sarcoidosis in past 22 years.Results The most frequent age at onset of sarcoidosis was 30～50 years old.Female patients were more than that in male patients. X-ray test of chest was the major way to diagnose the disease at early stage.The typing of lymphocytes in broncho-alveolar lavage fluid(BALF) has valuable to diagnose,but confirmed diagnosis depended on biopsy of histopathology.Conclusions Glucocorticoid is effective drug treatment for the most the patients who are at stage Ⅰ and Ⅱ. Every patient should be treated individually .If necessary,we should add immunosuppressors.

Purpose:To study the effectiveness and safety o f first-line chemotherapy with GEM-Cis 3-week regimen in routine care of Chin ese patients with advanced NSCLC. Methods:Gem-Cis 3-week regimen was used as first line chemoth erapy to treat stage Ⅲb/Ⅳ NSCLC patients, measurements of effectiveness includ ed clinical benefit and significant clinical response (SCR), and side events of GEM-Cis in the treatment of stage Ⅲb/IV NSCLC. Results:221 patients with cytological or pathological confirmed stage Ⅲb or IV NSCLC were enrolled, 209 eligible for effectiveness and safety analysis. Median age 58 years (range, 29 to 79 years); males: females, 67.5%∶ 32.5%; stage Ⅳ: ⅢB, 52.5%∶47.8 %; KPS

Objective To explore the effects of long term preventive treatment and patient education on asthmatic patients after acute attack Methods Prevention,treatment,and education were underwent for two to five years in 78 asthmatic patients after acute attack Frequency of exacerbation,lung function and laboratory parameters were monitored while treatment regimen was adjusted according to above results Results Regular prevention and management resulted in improvement of lung function and symptom as well as quality of life in all the patients Mmeanwhile less frequences of acute attack,emergency department visit,and hospital stay were observed,leading to reduction of medical expenditure Conclusion Long term prevention,treatment and education for asthmatic patients after acute attack are effective for better asthma control

Objective:To explore the expression of intercellular adhesion molecule-1(ICAM-1 )induced by cigarette smoking extract(CSE) as well as the influence of the adenovirus E1A gene in pulmonary epithelial cells.Methods:A549 cells were transfected with a plasmid carrying the adenovirus E1A gene and stable trasfectants expressing E1A protein were selected. The cells were tested for the expression of ICAM-1 after stimulation with different concentrations of CSE.Results:ICAM-1expression was increased in A549 markedly with CSE stimulation,and the higher CSE concentration were,the more expression of ICMA-1 was observed. As compared with parental cells or cells transfected with control plasmid, ICAM-1 expression was markedly increased with stimulation of different concentrations of CSE in E1A-positive A549 cells.Conclusion:CSE exposure induces the surface expression of ICAM-1 and adenovirus E1A gene can markedly increase ICAM-1 expression induced by CSE in pulmonary epithelial cells, which suggest that latent adenovirus infection may amplify the inflammation process present in airways of smokers.

Objective To analyse the changes of metabolic parameters and condition of metabolic syndrome(MS)in females with obstructive sleep apnea-hypopnea syndrome(OSAHS),and explore the interaction between OSAHS and MS.Methods Sixty females undergoing polysomnography were included,and were divided into simple snorer group(n=19),mild OSAHS group(n=21)and moderate to severe OSAHS group(n=20).Epworth sleepiness scale(ESS)scores and metabolic parameters were compared among groups.Forty-one patients with OSAHS were subdivided into group with MS(MS group,n=15)and group without MS(non-MS group,n=26).ESS scores,apnea hypopnea index(AHI),oxygen desaturation index(ODI)and lowest pulse oxygen saturation(LSpO_2)were compared between MS group and non-MS group.Results There was no significant difference in age,body mass index(BMI),total cholesterol(TC),triglyceride(TG),low density cholesterol(LDL),high density cholesterol(HDL),apolipoprotein A-I(apoA-I)and apolipoprotein B(apoB) among simple snorer group,mild OSAHS group and moderate to severe OSAHS group(P>0.05).Correlation analysis revealed ESS was positively related to AHI(r=0.327,P=0.011).ESS scores and proportions of hypertension,fasting plasma glucose(FPG)and MS were significantly higher in moderate to severe OSAHS group than those in simple snorer group(P<0.05).BMI,FPG,TG,proportion of hypertension,ODI and ESS score in MS group were significantly higher than those in non-MS group(P<0.05),while there was no significant difference in AHI and LspO_2 between these two groups(P>0.05). Conclusion ESS score may reflect the severity of OSAHS in females.Females with OSAHS matched for age and BMI have no difference in blood fat.With the increase of severity of OSAHS,glycometabolism can be impaired,the prevalences of hypertension and MS increase.MS can exacerbate the severity of OSAHS,indicating that MS and OSAHS interact with each other.

Important/potential value of macrolides has been proved in the management of chronic respiratory diseases by increasing basic and clinical trials.Through three face-to-face discussions,10 experts examined important data and drafted this consensus related to macrolides:(1) mechanism of nonantiinfective effects;(2) clinical use in chronic respiratory diseases;(3) cautions of long-term use.The mechanism out of non-antiinfective effects includes anti-inflammatory effect,modifying airway secretion,immune-regulation related to antibacterial effect,corticoid saving effect and anti-viral effect.The efficacy of long-term use of low-dose macrolides is definitely confirmed in diffuse panbronchiolitis,chronic rhinosinusitis.It is considerably used in bronchiectasia,cystic fibrosis,severe asthma and chronic obstructive pulmonary disease.Further studies should be conducted in cryptogenic organizing pneumonia and respiratory viral infection.It should be paid attention to its possible adverse effects (including drug interactions,cardiac toxicity,ototoxicity and disturbance of intestinal flora) and drug resistance in long-term use.A Chinese consensus for non-antiinfective effects and clinical use of macrolides is developed for the first time,which aims to expand their rational use and the further research.

OBJECTIVETo investigate CTLA4-Ig's potential role in therapy for allergic asthma by blocking B7/CD28 interactions with cytotoxic T lymphocyte antigen 4-Ig (CTLA4-Ig).

METHODSWe divided BALB/C mice into the three groups: Sham/Sham (control), ovalbumin (OVA)/OVA and mCTLA4-Ig. Blood, bronchoalveolar lavage, histology and determination of cytokines were performed 24 hours after airway challenge.

RESULTSIn the OVA/OVA group, the number of cells, the percentage of inflamed cells and the level of IL-4 in BALF were increased. Airways in our murine model for allergic asthma underwent pathological changes, which were significantly reduced after treatment with mCTLA4-Ig.

CONCLUSIONBlockage of co-stimulation with mCTLA4-Ig can inhibit allergy-specific response of T cells, and asthmatic response as well.

AIM: To study the pathological change in mouse organs immunitied by inactivated SARS-CoV vaccine. METHODS: Inactivated SARS-CoV vaccine was injected into BALB/c and C57BL/6 mice. Anti-SARS antibody was analyzed by ELISA. After 8 weeks, the immunitied mice were killed and those organs were analyzed by pathological methods. RESULTS: Anti-SARS antibody in mice was positive after 8 days. Only minimal injury was observed in a few lungs and livers, but the other organs were not. CONCLUSIONS: Inactivated SARS-CoV vaccine induced mice to create antibody, whereas they did not cause severe injury. This result will be valuable for vaccine into clinical research. [
