Objective To learn the prevelance of Acinetobacter baumannii and its drug resistance related with Ⅰ class integron. Methods 22 kinds of antibiotics commonly used in our hospital were used to detect the sensitivity of the clinically separated Acineto-bacter baumannii.Methods PCR was used to detect Ⅰ class integron enzyme gene of Acinetobacter baumannii,and then parts of variable region of Ⅰ class integron enzyme gene were amplified and analyzed for gene sequence.Results The drug resistance of Acinetobacter baumannii phenomenon was very serious,which was multiple drug resistance.The resistance rate of Acinetobacter baumannii to CPZ/SB was 1.2%.And the resistance rates to tigecycline,ofloxacin,imipenem,biapenem,and amikacin were 1 5.4%-69.5%,but the resistance rates to other antibiotics were above 71%.There were 72 of 102 strains including Ⅰ class integron (positive rate was 70.2%).The resistance of strains with Ⅰ class integron was stronger than that of the strains without.The varia-ble area of Ⅰ class integron produced the same enzyme bands when analyzed with double enzyme,suggesting the Acinetobacter bau-mannii was homologous.The gene sequence analysis of Ⅰ class integron showed that the Ⅰ class integron of the Acinetobacter bau-mannii carried kinds of resistant genes such as aacA4,catB8 and aadA13.Conclusion From 2010 to 2013,the Acinetobacter bau-mannii in our hospital is highly resistant to cephalosporins,broad-spectrum penicillin,aminoglycosides and fluoroquinolones and is severely multiple drug resistant.So the antimicrobial drugs for the treatment of infections caused by Acinetobacter baumannii are limited.Ⅰ class integron is closely related to the multiple drug resistance of Acinetobacter baumannii.

Choroidal neovascularization( CNV) is a common severe complication of ocular fundus diseases, with great potentiality to cause blindness. The treatments of CNV include photodynamic therapy ( PDT ) and anti-vascular endothelial growth factor( VEGF) therapy. However, PDT produces little visual benefits, and may result in ischemia, inflammatory responses, even the secondary expressions of VEGF. Anti-VEGF therapy sustained visual efficiency by repeated injections, causing economic burden and adverse effects related to injection. Recently, PDT combined with anti-VEGF therapy has progressed in laboratory and clinical research. Therefore, the combined modality therapy became one of the treatment options for CNV. In order to reduce the side effects of mono -therapy, further study is required to determine appropriate combinations and dosage.

Objective To study the effect of acarbose on vascular endothelial function in patients with impaired glucose tolerance (IGT).Methods Fifty-six cases with IGT were chosen by OGTT,and they were divided into control group(27 cases) and therapy group(29 cases) by systematic sampling.The patients in control group were received placebo,the patients in therapy group were given acarbose 25-50 rug,3 times daily for 12 weeks.The body mass index (BMI),blood fat,fasting blood glucose (FPG),fasting insulin (FINS),glycosylated hemoglobin (HbA1c),high sensitivity C-reactive protein (hs-CRP),von Willebrand factor (vWF),2 h post-meal glucose (2hPG),2 h post-meal insulin (2hINS) and brachial artery endothelium-dependent dilation (EDD) was detected before and after treatment in two groups.Results Compared with that before treatment,BMI,2hPG,2hINS,HbA1c,hs-CRP and vWF were decreased and brachial artery EDD was improved after treatment in therapy group[ (24.69 ± 2.62) kg/m2 vs.(22.02 ± 2.59)kg/m2,(9.26 ± 1.02) mmol/L vs.(7.43 ± 0.95) mmol/L,(42.17 ± 9.98) U/L vs.(34.76 ± 9.86) U/L,(6.03 ±0.67)％ vs.(5.37 ±0.56)％,(5.45 ± 1.93) mg/L vs.(4.52 ± 1.55) mg/L,(187.22 ±26.57)％ vs.(165.13 ± 23.86)％,(6.08 ± 1.22)％ vs.(7.94 ± 1.25)％ ] (P ＜ 0.05 or ＜ 0.01).There was no significant difference before and after treatment in control group (P ＞ 0.05).Conclusion Acarbose can improve brachial artery EDD in patients with IGT by increasing insulin sensitivity and decreasing postprandial hyperglycemia and inflammatory factor,which delays the progression of diabetic mellitus and atherosclerosis.
