Objective To study the association between serum interleukin-33 (IL-33) level and human stromelysin-2 (ST2) level in patients with rheumatoid arthritis (RA) associated with interstitial lung disease (RA-ILD) and its correlation with lung function and other laboratory parameters.Methods Two hundred and forty-five newly diagnosed RA patients during March 2012 to March 2013 in the in-patient and out-patient clinic of the First Affiliated Hospital of Liaoning Medical College were enrolled into this study.Patients were further divided into RA group (n=187) and RA-ILD group (n=58).Sixty subjects who came to the hospital for routine health check-up was composed of the normal control group.The clinical data of the two groups and controls were collected and their serum IL-33 and ST2 concentrations were measured.The t test was used to compare the difference between the two groups.Multiple variance analysis was used to com-pare the difference between groups.Pearson's correlation analysis was applied to explore the relationship between IL-33 concentrations and related variables.Results ① This study showed that the prevalence of RA associated interstitial lung disease was 23.7％(58/245).② The concentration of IL-33 [(746±43) pg/ml] and ST2 [(3413±169)pg/ml] of the RA-ILD group was significantly higher than that of the RA group [(433±42) pg/ml,(1500±147) pg/ml] (P＜0.01).③The vital capacity (VC％),forced vital capac-ity (FVC％),maximal midexpiratary flow curve (MMF％) and carbon monoxide diffusing capacity (DLCO) of the RA-ILD group were significantly lower than those of the RA group.④ The serum level of IL-33 was negatively correlated with that of RF and ACPA (IL-33 and RF,r=0.82,P＜0.01; IL-33 and ACPA,r=0.55,P＜0.01).Serum level of IL-33 was negaitively correlated with DLCO (r=-0.80,P＜0.01).Conclusion IL-33 participates in the pathogenesis of RA; and may be involved in the pathogenesis of RA-ILD.

OBJECTIVE To compare the bacterial resistance of wounds and clinical features in burned patients in intensive care unit (ICU) with those in general wards (GW) in the same period so as to provide basis for clinical prevention and treatment. METHODS Nineteen cases with wound infection admitted to the burn unit during June and July in 2005 were included in the retrospective study, 4 cases with 114 bacterial strains were from ICU and 15 cases with 47 bacterial strains were from GW respectively. The clinical features, bacterial culture and sensitivity test to antibiotics were analyzed. RESULTS Susceptibility to bacterial infection in ICU patients was significant than those in GW. The prevalent bacterial strains in ICU were Pseudomonas aeruginosa (PAE), Staphylococcus aureus (SAU) and Acinetobacter baumannii (ABA). In contrast, SAU, ABA, Klebsiella pneumoniae (KPN) and PAE prevailed in GW. Drug resistance of PAE, ABA and KPN to some kinds of antibiotics in ICU was severer than those in GW. CONCLUSIONS There is relatively great difference in bacterial constitution and drug resistance ratio between ICU and GW. To take certain disinfection and isolation measures could effectively prevent bacterial strains from transmitting among the wards.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

Objective To evaluate the effect of acupressure on chemotherapy-induced digestive tract reaction of malignant tumor patients.Methods We searched Pubmed,Medline,Embase,AMED,Cochrane Library,Cancerlit and Cinabl,China Biology Medicine disc (CBM),China National Knowledge Infrastructure (CNKI),VIP database (VIP)and Wanfang database,the databases were searched from the establishment of the database to March 2014.We identified randomized controlled trials (RCTs) and of acupressure on chemotherapy-induced digestive tract reaction for malignant tumor patients.Results In total,8 RCT,959 patients were included.Meta-analysis showed that compared with the no implementation of acupressure,acupressure could effectively reduce the frequency,duration and severity of chemotherapy-induced nausea,vomiting and retching.Meanwhile,acupressure could decrease anti-emetic medication dosage,but could not increase quality of life.Conclusions Acupressure can improve the digestive tract reaction of malignant tumor patients,alleviate the suffering of patients.Meanwhile acupressure couldn't increase the medical burden and mental burden of patients.More attention should be paid to the effect of acupressure on baseline level of state anxiety,functional state and more items.

Sodium houttuyfonate (SH) is a derivative of effective component of a Chinese material medica, Houttuynia cordata, which is applied in anti-infection of microorganism. But, the antimicrobial mechanisms of SH still remain unclear. Here, we firstly discovered that SH effectively inhibits the three types of virulence related motility of.Pseudomonas aeruginosa, i.e., swimming, twitching and swarming. The plate assay results showed that the inhibitory action of SH against swimming and twitching in 24 h and swarming in 48 h is dose-dependent; and bacteria nearly lost all of the motile activities under the concentration of 1 x minimum inhibitory concentration (MIC) (512 mg x L(-1) same as azithromycin positive group (1 x MIC, 16 mg x L(-1)). Furthermore, we found that the expression of structural gene flgB and pilG is down-regulated by SH, which implies that inhibitory mechanism of SH against motility of P. aeruginosa may be due to the inhibition of flagella and pili bioformation of P. aeruginosa by SR Therefore, our presented results firstly demonstrate that SH effectively inhibits the motility activities of P. aeruginosa, and suggest that SH could be a promising antipseudomonas agents in clinic.
