Susceptibility testing was performed by disk diffusion(K-B)method. RESULTS Totally 541 strains of Enterobacteriaceae were cultivated altogether and ESBLs-producing bacteria were 135 strains. The ESBLs- producing strains were sensitive to imipenem, and the resistance rates to it were 0.00% . The resistance rates of ESBLs-producing strains to cefoperazone/sulbactam and piperacillin/tazobactam were 31.11% and 44.44%, respectively . The multi-drug-resistance (MDR) rate of ESBLs-producing strains was higher than that of strains no producing ESBLs (P

Objective Aortic arch obstruction is a commonly associated malformation in the patients with Taussig-Bing anoma- ly.Herein,we reported our outcomes of single stage corrections in patients with the Taussig-Bing anomaly associated with aortic arch obstruction.Methods Between May,2000 and Dec,2006,12 patients with Taussig-Bing anomaly associated with aortic arch obstr- uction (5 patients associated with interrupted aortic arch) underwent arterial switch operation with baffling of the left ventricle to neo- aorta.The corrections of aortic arch obstruction included extended resection combined with end to end anastomosis to aortic arch or end to side anastomosis to ascending aorta.Results The hospital mortality rate was 25% (3/12).The ventilating time and ICU stay were (7.4?2.1) days and (11.7?4.6) days,respectively.No reoperation because of residual anomalies was required.Conclusion Tanssig-Bing anomaly,especially associated with aortic arch obstruction,is different from transposition of great artery.The opti- mized operative indications,techniques and the managements of aortic arch obstruction are discussed in the article.

Multi-component traditional Chinese medicines are an innovative research mode for traditional Chinese medicines. Currently, there are many design methods for developing multi-component traditional Chinese medicines, but their common feature is the lack of effective connection of the traditional Chinese medicine theory. In this paper, the authors discussed the multi-component traditional Chinese medicine design methods based on medicinal property combination modes, provided the combination methods with the characteristics of traditional Chinese medicine for the prescription combinations, and proved its feasibly with hypertension cases.

BACKGROUNDAs the incidence of type 2 diabetes is rapidly increasing, prevention of the disease should be considered as a crucial objective in the near future. Several studies have shown angiotensin receptor blockers (ARBs) may contribute to the prevention of new-onset type 2 diabetes. This study was conducted to determine if ARBs as monotherapy or combination therapy may experience a decreased incidence of new-onset type 2 diabetes and prevent cardiovascular events.

METHODSRelevant experimental and clinical studies were identified by searching MEDLINE (1969 to May 30, 2011) to extract a consensus of trial data involving the effect of ARBs on prevention of new-onset type 2 diabetes and cardiovascular events. Studies were included if they were randomized controlled trials versus placebo/routine therapy. A random-effects model was utilized. Subgroup and sensitivity analyses were conducted.

RESULTSEleven trials were identified, including 82 738 patients. ARBs prevented new-onset type 2 diabetes (odds ratio 0.8 (95%CI 0.76, 0.85)). Regardless of indication for use, essential hypertension (seven trials), impaired glucose tolerance (one trial), cardiocerebrovascular disease (two trials) or heart failure (one trial), reductions in new-onset type 2 diabetes were maintained (0.75 (0.69, 0.82), 0.85 (0.78, 0.92), 0.80 (0.76, 0.85) and 0.80 (0.64, 0.99), respectively). No statistical heterogeneity was observed for any evaluation. However, ARBs did not significantly reduce the odds of all-cause mortality, myocardial infarction and heart failure versus control therapy among all of these studies. But ARBs did reduce the odds of cardiac death and heart failure among the heart failure study versus control therapy.

CONCLUSIONARBs have significant ability to reduce risk of developing new-onset type 2 diabetes but does not improve cardiovascular outcomes over the study follow-up periods among all of included studies.

OBJECTIVETo study the relationship between phosphatidylinositol-3-kinases(PI3K)/protein-serine-threonine kinase(AKt) signaling pathway and orthodontic tooth movement.

METHODSTwenty-four rabbits were chosen to establish rabbit models for the study. The right maxillary teeth of each animal treated by orthodontics were as the test side, and the untreated left teeth were as the control side. The animals were sacrificed at 3, 5, 7, 14 d, respectively. The prepared tissue specimens were processed for the study. The changes of the expression of PI3K, AKt in periodontal tissues were detected by real-time quantitative-polymerase chain reaction (RQ-PCR) and Western blot techniques.

RESULTSRQ-PCR showed that the expression of PI3K, AKt mRNA dramatically changed at 3 d. The expression of PI3K, AKt mRNA in the test side was higher than the control side, especially at 7 d, and then decreased. Compared with the control side, there was statistical significant difference in the test side(P < 0.05). The study obtained consistent conclusion from Western blot and RQ-PCR.

CONCLUSIONExpression of PI3K, AKt in rabbit periodontal tissues increase during orthodontic tooth movement, which prompts that PI3K/AKt signal pathways relate to orthodontic tooth movement and PI3K/AKt signal pathway involve in the periodontal tissue remodeling.
