目的:观察妊娠期孕鼠给予葡萄球菌肠毒素B(SEB)对其新生子代鼠脾脏淋巴细胞体外增殖的影响。方法:在SD大鼠妊娠第16天给予尾静脉注射15μg SEB,同时设立磷酸盐缓冲液(PBS)对照组。获取出生后3 d的新生鼠脾脏并分离淋巴细胞,将淋巴细胞与Con A或SEB共培养3 d,流式细胞仪检测新生鼠脾脏淋巴细胞亚群,液体闪烁仪测定细胞的增殖能力。结果:SEB组新生鼠脾脏中CD4^+T细胞比例在Con A或SEB刺激第1天分别较PBS组明显增加,但在第2~3天却明显降低(P<0.05~P<0.01);而SEB组新生鼠脾脏中CD4^+TCR Vβ8.2^+T细胞比例在Con A或SEB刺激的第1天及CD8^+TCR Vβ8.2^+T细胞比例分别较PBS组明显增加(P<0.05~P<0.01)。SEB组新生鼠脾脏淋巴细胞在Con A或SEB刺激后第1天增殖能力明显强于PBS组,但在第2~3天的增殖能力却又明显低于PBS组(P<0.05~P<0.01)。结论:妊娠期孕鼠给予SEB可以影响新生鼠脾脏淋巴细胞的体外增殖。

DEAR EDITOR, We read with interest the article by Wang and colleagues regarding the role of wildlife in the transmission of antimicrobial resistance （AMR）（Wang et al., 2017）. Although we appreciate the efforts in reviewing this important topic, we would like to comment on some statements that we believe are not up-to- date or properly cited.

Aim and Background: It is estimated that up to 20% of patients coming for elective surgery are smokers and carry a risk of perioperative complications. Though smoking cessation and its impact on perioperative outcome are widely investigated worldwide we were unable to find any data in Pakistan. The objective of the study is to determine the impact of the duration of smoking cessation before elective surgery on intraoperative hemodynamics and postoperative pain in Pakistani population. Methods: It was a prospective cohort study conducted at the Aga Khan University Hospital Karachi, Pakistan, for one-year duration. A total of 260 patients scheduled for elective noncardiac surgery under general anaesthesia were recruited. Surgery under regional anaesthesia and minor surgery under general anaesthesia were excluded. Data on self-reported duration of smoking cessation by patients, intraoperative haemodynamics, postoperative pain scores and duration of hospital stay were collected by independently trained data collectors from the preoperative area until the patient is discharged from the hospital. Results: A data from 256 patients were analyzed. On the basis of self-reported duration of preoperative smoking cessation, patients were divided into 4 groups (Group 1: less than 2 days, Group 2: more than 2 days to 7 days, Group 3: more than 7 days to 4 weeks and Group 4: more than 4 weeks). It was found that the longer the duration of cessation of smoking is the less haemodynamic changes and lower postoperative pain scores. Length of stay did not show any difference among all four groups. No major postoperative pulmonary complication was found in any study patient. Conclusions: Duration of cessation of smoking before elective surgery is a significant predictor of intraoperative haemodynamics and early postoperative pain in Pakistani population. A short duration of smoking cessation also helps to avoid some of the adverse effects and reduces periopera
