5Mesenchymal stem cell therapy in patients with small bowel transplantation:Single center experience显示文摘AIM:To study the effects of mesenchymal stem cell(MSC) therapy on the prevention of acute rejection and graft vs host disease following small bowel transplantation.METHODS: In our transplantation center, 6 isolated intestinal transplants have been performed with MSC therapy since 2009. The primary reasons for transplants were short gut syndrome caused by surgical intestine resection for superior mesenteric artery thrombosis(n = 4), Crohn's disease(n = 1) and intestinal aganglionosis(n = 1). Two of the patients were children. At the time of reperfusion, the first dose of MSCs cultured from the patient's bone marrow was passedinto the transplanted intestinal artery at a dose of 1000000 cells/kg. The second and third doses of MSCs were given directly into the mesenteric artery through the arterial anastomosis using an angiography catheter on day 15 and 30 post-transplant.RESULTS: The median follow-up for these patients was 10.6 mo(min: 2 mo-max: 30 mo). Three of the patients developed severe acute rejection. One of these patients did not respond to bolus steroid therapy. Although the other two patients did respond to antirejection treatment, they developed severe fungal and bacterial infections. All of these patients died in the 2nd and 3rd months post-transplant due to sepsis. The remaining patients who did not have acute rejection had good quality of life with no complications observed during the follow-up period. In addition, their intestinal grafts were functioning properly in the 13th, 25th and 30th month post-transplant. The patients who survived did not encounter any problems related to MSC transplantation.CONCLUSION: Although this is a small case series and not a randomized study, it is our opinion that small bowel transplantation is an effective treatment for intestinal failure, and MSC therapy may help to prevent acute rejection and graft vs host disease following intestinal transplantation.Sait Murat Do?an Sel?uk K?l?n?

6饲料中添加蛋白酶对肉鸡性能、养分利用率、肠道形态和胴体品质的影响显示文摘试验在饲喂玉米、高粱为主的肉鸡日粮中补充大豆,并添加蛋白酶,研究蛋白酶对肉鸡性能、养分消化率、肠道形态和胴体品质的影响。试验选取1日龄AA肉仔鸡(43.8±1.31 g)256只,均为公鸡,随机分配到2×2试验设计方阵中,方阵包括正常组(玉米组和高粱组)和蛋白酶组(空白组和添加蛋白酶150 mg·kg^(-1)的试验组)。试验1~21 d为第一阶段,22~42 d为第二阶段。试验结果表明,第二阶段中,日粮中添加蛋白酶极显著提高肉鸡的平均日增重(ADG,P<0.01),在整个试验过程中显著提高(P<0.05)。在各个时期,正常组对肉鸡生产性能均无显著影响(P>0.05)。19~21 d时,添加蛋白酶可显著提高肉鸡的表观代谢能(AME),干物质(DM)、总能量(GE)和养分消化率(P<0.05)。此外,日粮以高粱为主时,AME、GE消化率有降低趋势(P=0.05),氮沉积率也有降低趋势(P=0.08)。40~42 d时,日粮中添加蛋白酶可显著提高AME,DM、GE和氮沉积率(P<0.05)。21 d时,日粮中添加蛋白酶极显著增加肠绒毛高度、肠绒毛与隐窝深度比值,极显著降低十二指肠、空肠、回肠的隐窝深度(P<0.01)。42 d时,日粮中添加蛋白酶显著增加空肠肠绒毛高度、绒毛高度与隐窝深度比值,显著降低隐窝深度(P<0.05)。日粮中添加蛋白酶显著增加胸肌重、24 h p H,显著降低胸肌的滴水损失(P<0.05)。试验结果表明,饲养阶段日粮中添加复合蛋白酶可提高肉鸡ADG;在第一阶段可改善AME、DM、GE和氮沉积率和肠道形态。补充蛋白酶可提高出栏重、胸肌重和24 h pH,降低胸肌的滴水损失。低单宁高粱日粮与玉米日粮相比,对肉鸡性能的影响相近。Xu X Wang H L Pan L Ma X K Tian Q Y Xu Y T Long S F Zhang Z H Piao X S 2017饲料博览2017,0,1:2
7抗生素使用的时间长短和使用时的生命阶段与全因/特定原因死亡风险的关系:一项前瞻性队列研究显示文摘过度使用抗生素一直是一个重要的临床问题,抗生素使用与肠道微生物菌群的改变有关,肠道菌群的改变与各种慢性疾病如心血管病和癌症的风险有关。此外,抗生素使用的时间可能是过早死亡的一个危险因素。研究者调查了成年期间使用抗生素的生命阶段和使用持续时间与全因和特定原因死亡风险的关系。该项前瞻性队列研究包括来自护士健康研究、均未患有心血管病或癌症的37516名年龄≥60岁的女性,收集其中年(40~59岁)和老年(≥60岁)使用抗生素的时间(无,<15d,15d至<2个月,或≥2个月)。研究者根据抗生素的使用时间估计10年内全因死亡率和心血管病或癌症的死亡风险比(HR)。在355918人年的随访中,研究者记录了所有原因导致的4536例死亡(包括728例心血管病死亡和1206例癌症死亡)刘青(译) 叶鹏(摘 审校) Heianza Y Ma W Li X Cao Y Chan A Rimm EB Hu FB Rexrode K Manson JE Qi L 2020中华高血压杂志2020,28,2:2
