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.

OBJECTIVE:To explore the treatment effect and complication prevention of various stent materials for intracranial arteriostenosis.METHODS:A computer-based online search of Science Direct and Ei database (1998-01/2009-10) was performed for English articles with the key words of "intracranial arteriostenosis,stent placement" In addition,CNKI and CBM database (1998-01/2009-10) were searched for related Chinese articles with the same key words in Chinese.Moreover,related works were manually searched.Studies regarding various stent materials for intracranial arteriostenosis were included,including basic and clinical experiments.RESULTS:Multicenter studies of worldwide show that stent implantation displays obvious advantages in treating carotid artery stenosis compared with carotid endarterectomy.Recently,with developing of balloon and stent compliance,as well as stent technology,and application of various novel materials and cerebral protection device,stent has become a safe and effective therapy for intracranial arteriostenosis.However,complications following stent implantation,such as restenosis,ischemic stroke,cerebral hemorrhage hypertransfusion syndrome,and cerebral angiospasm,limit its application.CONCLUSION:The safety and efficacy of intracranial stent implantation remains validation of multicenter and perspective studies.High incidence of restenosis following stent implantation requires further improvement.

Objective To investigate the value of CT and mammography for diagnosing breast masses.Methods 61 cases with breast mass confirmed pathologically were studied comparatively. The diagnostic accuracy was compared between the two mentioned diagnostic methods.Results The qualitative accuracy of CT in diagnosis of breast cancer, galactocele, lipoma, fibroadenoma, gynecomastia, breast hyperplasia was 80%(8/10), 100%(2/2), 100%(1/1), 100%(27/27), 100%(7/7), 100%(14/14), respectively. The qualitative accuracy of mammography in diagnosis of the above lesions was 70%(7/10), 50%(1/2), 0%(0/1), 81%(22/27), 43%(3/7), 71%(10/14), respectively. In the cases of breast cancer, mammography could detect clustered microcalcification foci in 4 of the 10 cases(40%). But CT could detect none of them. Mammography was superior to CT in demonstrating cluster microcalcifications which are important basis for diagnosing breast cancer. The overall accuracy of CT and mammography for diagnosing breast masses were 97% and 71%.Conclusion CT has a higher accuracy than mammography in determining the nature of breast mass. The synthetic application of both the two methods may raise the diagnostic level for early stage breast cancer.

Nonunion or delayed union remains one of the major complicatio ns of fractures. Repair of fractures involves a sequence of dynamic events which ultimately restore the integrity of bone and its biomechanical properties, incl uding such methods as surgery, internal fixation, bone grafting, external fixati on, electrical stimulation, ultrasound, and high-energy extracorporeal shock wa ve. The preferred management of nonunion and delayed union is autologous bone gr afting. However, the supply of suitable bone is limited and it often results in additional morbidity to the donor site. Recently some advances have been made in the therapeutic principle for nonunion or delayed union. It is aimed at providi ng non-invasion, less complication, and safe treatment. This article introduces the development of some effective and safe therapies for nonunion or delayed un ion.

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.
