Objective:This study was conducted to evaluate whether or not immediate breast reconstruction influences quality of life and patient body image satisfaction outcomes among Chinese women with breast cancer compared with modified radical mastecto-my. Methods:Sixty patients with breast cancer and were operated from July 2011 to July 2012 in Cancer Institute&Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were included. These patients were divided into two groups:Ⅰ(30 patients) underwent modified radical mastectomy andⅡ(30 patients) underwent mastectomy with immediate breast reconstruction. Pa-tient satisfaction with breast reconstruction was evaluated by functionally assessing cancer therapy-breast cancer scale (FACT-B) and the scales that we designed. Results:No significant differences were observed between the two groups in terms of baseline characteris-tics, histopathological characteristics, and incision conditions (P>0.05). The patients in groupⅡ(immediate breast reconstruction) ex-hibited improved body image satisfaction outcomes (41.1 ± 10.8 vs. 33.2 ± 8.8, P=0.003);this difference was still observed after adjust-ment for confounding factors was performed by multiple linear regression. No significant difference was found between the two groups in terms of total FACT-B score and psychological evaluation score (P>0.05). Conclusion:Chinese women who prefer immediate breast reconstruction exhibited an improved body image satisfaction.

Objective To investigate the distribution and drug resistance of bacterial pathogens isolated from orthopedic wounds.Methods Data of bacterial strains isolated trom orthopedic wounds in the Third Hospital of Hebei Medical University from January 2008 to December 2012 were retrospectively analyzed.Strains were identified by using French bioMérieux Vitek32 identification system,and the drug susceptibility was tested by Kirby-Bauer method.Chi-square test for linear trend was performed to reveal the changes of distribution and drug resistance of the strains.Results A total of 2 456 bacterial strains were isolated,vith 1 652 (67.26％) gram-negative bacilli,777 (31.64％) gram-positive cocci,26 (1.06％) fungi,and 1 (0.04％) gram-positive bacillus.The top five pathogens were Staphylococcus aureus (666 strains,27.12％),Pseudomonas aeruginosa (606 strains,24.67％),Acinetobacter baumannii (355 strains,14.45％),Escherichia coli(188 strains,7.65％) and Enterobacter cloacae (187 strains,7.61％).The positive rate of Acinetobacter baumannii was on the rise during 2008 and 2012 (x2 =35.266,P ＜ 0.0l).The rates of pan-drug resistant strains in Acinetobacter baumannii and Pseudomonas aeruginosa were 6.20％ (22/355) and 0.17％ (1/606),respectively.The rates of extended-spectrum β-lactamases positive strains in Escherichia coli and Klebsiella pneumoniae were 39.89％ (75/188) and 29.23％ (19/65),respectively.The rates of methicillin-resistant strains in Staphylococcus aureus and coagulasenegative Staphylococcus were 40.69％ (271/666) and 52.38％ (22/42),respectively.The rate of vancomycin-intermediate strains in Enterococci was 3.70％ (2/54).The positive rate of methicillin-resistant &aphylococcus aureus was on the rise during 2008 and 2012 (x2 =18.317,P ＜ 0.01).Staphylococcus aureus were sensitive to teicoplanin,vancomycin and linezolid; Resistance rates to rifampicin and amikacin were 11.29％-33.33％; Resistance rates to penicillins and erythromycin were 76.80％-100.00％; Resistance rates to cefazolin,cefuroxime,cefoxitin,amikacin and levofloxacin were on the rise (P ＜ 0.05) ; And resistance rates to sulfamethoxazole (28.11％-48.35％) were on the decline in the same period (P ＜ 0.01).Resistance rates of Pseudomonas aeruginosa to imipenem,meropenem and sulfamethoxazole were on the rise (P ＜ 0.05) ; Resistance rates to ciprofloxacin,levofloxacin,amikacin,gentamicin and piperacillin/ tazobactam were on the decline (P ＜ 0.05) ; Resistance rates to cefoperazone/sulbactam were the lowest (9.15％-20.51％).Resistance rates of Acinetobacter baumannii to imipenem,meropenem,levofloxacin,piperacillin/tazobactam,sulfamethoxazole were on the rise (P ＜ 0.01); Resistance rates to cefoperazone/ sulbactam were the lowest (11.86％-19.70％).Escherichia coli and Enterobacter cloacae were sensitive to imipenem and meropenem,and the resistance rates to cefoperazone/sulbactam and piperacillin/tazobactam were low (0-14.29％); Resistance rates of Escherichia coli to piperacillin,cefepime,amikacin,levofloxacin,cefoperazone/sulbactam were on the decline (P ＜ 0.05) ; Resistance rates of Enterobacter cloacae to cefoxitin were on the rise (P ＜ 0.01),while the resistance rates to piperacillin,ceftazidime,cefoperazone,ceftriaxone,levofloxacin were on the decline (P ＜ 0.05).Conclusion During 2008 and 2012,the predominant bacterial pathogens of orthopedic wound in patients of the Third Hospital of Hebei Medical University are Staphylococcus aureus,Pseudomonas aeruginosa,Acinetobacter baumannii,Escherichia coli and Enterobacter cloacae,and most strains are multiple drug resistant.

Acute cerebral infarction （ACI）， also known as ischemic stroke， is a disease with a high disability rate， which brings heavy burdens to society and families. Its pathogenesis is related to many factors， of which the inflammatory theory is one of the important mechanisms. In the early stage of ACI， microglia are activated， and the inflammatory mediators， such as interleukins and tumor necrosis factor-α （TNF-α）， released by them induce vascular endothelial cells to express adhesion molecules. The circulating leukocytes （neutrophils， monocyte-macrophages， etc.） are promoted to roll and adhere to the injured vascular endothelium， migrate and cross the blood-brain barrier， penetrate and infiltrate the brain parenchyma， and further expand the local inflammatory response by releasing a variety of proinflammatory mediators， thus exacerbating the tissue injury at the injury site and ischemic penumbra. Traditional Chinese medicine （TCM） has advantages in treating the disease. TCM believes that the occurrence of stroke is related to blood stasis caused by various reasons， which block the brain vessel. This article reviewed the research progress on the effect of activating blood therapy on inflammatory factors in patients with ACI in recent years and discussed its regulation of inflammatory factors in ACI such as interleukin-1 （IL-1）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， interleukin-10 （IL-10）， TNF-α， C reactive protein （CRP）， and monocyte chemotactic protein-1 （MCP-1）， hoping to elucidate the scientific connotation of TCM treatment of ACI and lay the foundation for further research.
