Objective To explore the signs of consistent changes of intestinal flora in type 2 diabetes mellitus (T2DM) and diabetes kidney disease (DKD) patients, by studying the key change characteristics of intestinal flora in these patients. Methods Thirty patients with T2DM,twenty-five patients with DKD were involved. Thirty healthy patients with matching age and sex were also involved as the control group. Fecal and serum specimens were collected from both the study group and the control group. High-throughput sequencing technology was used to sequence the 16S rDNA-v4 region of fecal samples;interleukin-6 (IL-6) and C-reactive protein (CRP) were detected by electrochemical luminescence and immunoturbidimetry. Microbiome analysis software QIIME (v1.9.1) was used to analyze the composition and diversity of intestinal flora. Microbial diversity analysis software LEfSe was used to compare intestinal bacteria markers differences between the study group and the healthy control group. The diagnosis model was established by the random forest method. The change characteristics of intestinal flora function were predicted by the PICRUSt. Results The intestinal flora diversity of DM and DKD patients was significantly different from that of the healthy control group (P<0.05). T2DM and DKD patients harbored lots of similar changes. For example, there was a significant decrease in Lachnospira, Faecalibacterium, Roseburia and Coprococcus(P<0.05). However, there was also a disease-specific pattern of imbalance between the two disease. There was a significant increase in Bacteroides in T2DM patients, and in Lactobacillus, Slackia, Anaerotruncus,Haemophilus and Enterococcus in DKD patients. Functional prediction was also confirmed that T2DM and DKD patients had more consistent changes. The correlation analysis between serum inflammatory indicators of T2DM and DKD and bacteria suggested that the decrease of beneficial bacteria in the intestinal tract of T2DM and DKD patients may be the cause of the increase of serum inflammatory indicators. Conclusion T2DM and DKD patients harbored lots of similar changes in intestinal flora, a decrease of bacteria producing butyrate,but there was also a disease-specific change between the two disease,providing a data basis for further studies to evaluate the risk of nephropathy in patients with diabetes by intestinal flora .

Objective To provide evidence for the rational use of antibiotics.Methods Analyze on the results of pathogen detec-tion and antibiotic susceptibility tests for the patients in the hospital from January 2013 to December 2013.Results There were 2 111 strains of pathogenic bacteria detected in 2013,among which the Gram-negative bacteria accounted for 75.5%(1 594/2 111). The main species were Klebsiella pneumonia,Escherichia coli,Acinetobacter baumannii,Enterobacter cloacae,Pseudomonas aerugi-nosa,Klebsiella oxytoca.Gram-positive bacteria accounted for for 20.3%(428/2 111),the main species of which were Streptococcus pneumonia,Staphylococcus aureus,Staphylococcus aureus and Enterococcus faecalis.There were 89 strains of fungi,which accoun-ted for 4.2%(89/2 111).The antibiotic susceptibility tests showed that Klebsiella pneumoniae′s drug resistance to 13 kinds of anti-biotics were all less than 25.00%.Escherichia coli,Acinetobacter baumannii,Pseudomonas aeruginosa displayed highly resistance to cephalosporin antibiotics while sensitive to Cefperazone-Sulbactam.The antibiotic resistance of Gram-positive bacteria to macrolide were greater than 70% while that to Vancomycin was 0.0%.Staphylococcus aureus and Staphylococcus epidermidis were highly re-sistant to penicillin.Conclusion The monitoring of bacterial resistance in hospital contributes to the rational use of antibiotics and avoiding the formation and spread of drug-resistant strains.

OBJECTIVE@#To evaluate the effectiveness of glucocorticoid in the management of olfaction in patients with chronic rhinosinusitis accompanied with nasal polyposis.@*METHOD@#The published studies of the effectiveness of glucocorticoid in the management of chronic rhinosinusitis with nasal polyposis were searched in the Medline, Cochrane, EMBASE, Springer and CNKI databases(from the date of establishment of the databases to December 2014). The trails selection based on inclusion criteria and the quality of the included studies was assessed and meta-analysis was performed with RevMan 5. 3 software.@*RESULT@#A total of 5 trials involving 325 patients were included. The Meta-analysis showed that oral glucocorticoid showed more significant improvement in subjective olfaction scores compared to placebo [SMD = -2.22, 95% CI (-3.94 - -0. 49), P 0.05], [SMD = 0.28, 95% CI (-0.08-0.64) P > 0.05].@*CONCLUSION@#According to current evidence, oral glucocorticoid can significantly improve subjective and objective olfaction among patients with CRSwNP, but nasal glucocorticoid cannot improve subjective or objective olfaction dysfunction.

Objective To explore the risk factors for healthcare-associated infection (HAI)caused by Candidain a hospital.Methods 64 patients with healthcare-associated(HA)Candidainfection in a hospital between January 201 1 and October 2013 were selected as case group,and 64 patients without HACandidainfection during the same period were as control group,clinical data of two groups of patients were analyzed.Results The mainCandidacau-sing HAI were Candidaalbicans(68. 75% ),followed by Candidatropicalis(15. 62% ),Candidaglabrata (9.38% )andCandidakrusei(6.25% ).The major infection sites were respiratory tract(67.19% ),urinary tract (18.75% )and digestive tract(10.94% ). Univariate analysis showed the risk factors for HA Candidainfection were age,length of hospital stay,diabetes,and malignant tumor and so on;multivariate logistic regression analysis showed that important risk factors for HACandidainfection were age(OR95% CI:2.57-33.67),length of hospi-tal stay(OR95% CI:2.17-25.37),malignant tumor(OR95% CI:1.04-15.23),chemotherapy(OR95% CI:1.76-20.63),and use of respirator(OR95% CI:4.67-96.37).Conclusion Risk factors for HACandidainfection are complicated,in order to reduce the incidence of HA Candidainfection,risk factors should be considered,and preventive measures according to risk factors should be made.

OBJECTIVE@#To evaluate the efficacy of specific immunotherapy (SIT) with standardized house dust mite allergen preparation for allergic rhinitis (AR).@*METHOD@#Fifty-five patients with allergic rhinitis caused by house dust mites were selected in this self-control study. Clinical efficacy was evaluated by symptom and sign score after two years of specific immunotherapy and compared with pre-treatment scores.@*RESULT@#After completing the study, a clinically significant reduction in symptom and sign score in these patients was noted, compared with that of pretreatment. And the difference was statistically significant (P < 0.01).@*CONCLUSION@#Standardized house dust mite allergen preparation is an effective treatment in patients suffering from allergic rhinitis due to house dust mites.
