常通口服液对炎症因子参与大鼠肠粘连的影响

目的:观察常通口服液对术后粘连大鼠血液中肿瘤坏死因子α(TNF-α),转化生长因子β1(TGF-β1),白细胞介素-1β、4、6、10(IL-1β、IL-4、IL-6、IL-10)水平的影响.方法:选用SD雄性大鼠,随机分为6组:正常对照组、模型对照组、四磨汤组及常通口服液低、中、高剂量组.除正常对照组外,其余大鼠均制备成肠粘连模型.各组于术后第7天取血,酶联免疫吸附法(ELISA)测定细胞因子水平;同时用肉眼观察法进行粘连程度肉眼分级.结果:常通口服液能显著减轻模型大鼠的肠粘连程度,降低术后肠粘连大鼠血清中致炎细胞因子TNF-α、IL-1β、TGF-β1、IL-6水平.但对抗炎细胞因子IL-4、IL-10水平无影响.结论:本实验为术后粘连临床疗效评价指标筛选提供了实验依据.     

Microcystin-LR promote intestinal secretion of water and electrolytes in rats.

We showed previously that exposure to microcystin-LR causes renal toxic effects in isolated perfused rat kidney, and that inflammatory mediators from supernatants of macrophages stimulated by microcystin-LR are involved in this process. The aim of this research was to examine water and electrolytes secretion in vivo, induced by microcystin-LR and supernatant of macrophages stimulated for this toxin (SUP.MphiS + MCLR), using perfused rat ileal segment and ligated intestinal loop models. We found microcystin-LR at 1 microg/ml (0.09 +/- 0.003* vs. control 0.07 +/- 0.001 g of secretion/2 cm of loop; P < 0.05*) and the SUP.MphiS + MCLR after 18 h postinoculation (0.10 +/- 0.003 vs. control 0.03 +/- 0.002 g/cm) caused intestinal secretion. In addition, microcystin-LR caused significant sodium secretion (-2.18 +/- 0.72* vs. control 2.18 +/- 0.50 microEq g(-1) min(-1)), potassium (-0.26 +/- 0.04* vs. control 0.32 +/- 0.03 microEq g(-1) min(-1)), chloride (MCLR = -3.29 +/- 1.93* vs. control 0.88 +/- 1.25 microEq g(-1) min(-1)) and water (-0.012 +/- 0.004* vs. control 0.002 +/- 0.002 ml g(-1) min(-1)). We also demonstrated SUP.MphiS + MCLR to induce intestinal secretion of electrolytes (sodium, potassium, chloride) and water. These findings suggested that microcystin-LR and lamina propria macrophages-derived mediators are able to induce intestinal secretion in vivo, probably via inhibition of protein phosphatase.     

行气散外敷治疗结核性肠梗阻的疗效观察

目的:探讨中西医结合治疗结核性腹膜炎伴粘连性肠梗阻的疗效。方法:96例结核性腹膜炎合并肠梗阻患者随机分为治疗组及对照组,每组各48例,治疗组及对照组均在抗痨治疗的基础上给予常规禁食、持续胃肠减压、抗感染、补液支持等治疗,治疗组则在此基础上加用中药行气散外敷治疗。结果:治疗组疗效有效率为91.67%,优于对照组的64.60%(P<0.05);且治疗组的住院时间与对照组相比明显缩短,优于对照组(P<0.05)。结论:西医常规治疗的基础上结合中药行气散外敷治疗,具有良好的临床效果,在抗痨治疗的基础上能有效缓解肠梗阻,同时缩短住院时间,值得在临床上推广应用。     

Correlation analysis of intestinal flora and pathological process of type 2 diabetes mellitusOA

Objective: To observe the relationship between the different stages of type 2 diabetes mellitus(T2DM)and the intestinal flora and verify its underlying mechanism.Methods: T2DM rats were generated by high-fat diet(HFD) combined with intraperitoneal streptozotocin(STZ) injection. The rats were divided into four groups: the control group(fed with normal feed for1 month), the HFD group(fed with HFD for 1 month), the T2DM group(HFD combined with STZ and blood glucose ≥11.1 m M), and the unformed T2DM...     

益生菌对妊娠期糖尿病的影响及相关机制

妊娠期糖尿病(gestational diabetes mellitus, GDM)可对母体及其后代产生近期和远期的不良影响,GDM患者的肠道菌群与正常孕妇存在差异,肠道菌群结构及功能的改变影响了其发生发展。近年来,国外研究发现,益生菌可不同程度地影响GDM患者糖脂代谢,但具体机制不甚明确,短链脂肪酸、过氧化物酶体增殖...     

Cronkhite-Canada综合征三例报道并文献复习

Cronkhite-Canada综合征(CCS)目前被认为是一种非遗传性疾病,临床较为罕见,内镜下多表现为胃肠道多发息肉,临床上以消化道症状、皮肤色素沉着、脱发、脱甲等为主要表现。本文分析了2012年8月至2021年9月于山东大学齐鲁医院确诊为CCS的3例患者的临床特点及诊疗过程并作文献复习。CCS的诊断基于病史、体格检查、胃肠息肉的内镜检查和组织病理学结果,消化内镜是其最直接的检查手段。3例CCS患者内镜下均表现为胃肠道弥漫性多发息肉,均存在脱发、脱甲表现;病例1和病例3白蛋白水平均降低,病例2和病例3抗核抗体(ANA)阴性,病例1未查ANA,3例均无幽门螺杆菌(HP)感染。糖皮质激素及质子泵抑制剂(PPI)为CCS的主要治疗药物,病例1未使用糖皮质激素治疗,仅给予PPI及支持治疗,后期出现血便、肠坏死,起病6年后因胃癌行全胃切除术;病例2和病例3确诊CCS后给予泼尼松、PPI等治疗后好转。早期诊断、以糖皮质激素为中心的药物治疗、定期内镜检查和新的治疗方案可能为未来更好的预后提供更多实践经验,可提高临床医师对该病的认识和理解、减少漏诊和误诊。

肠道菌群与肾脏病的研究进展

肠道菌群即我们通常所说的“肠道微生物”，这类微生物不仅与营养、免疫、代谢有着重要关系，而且与疾病存在一定联系。虽然宿主-微生物群在健康和疾病中相互作用机制的探索处于起步阶段，但已有研究描述了肾病患者肠道菌群的变化，尽管二者之间的关系仍在发展中。本文基于“肠-肾轴”理念，对肠道菌群与肾脏疾病间关系的研究进展加以综述，此外还介绍了潜在的有针对性的治疗策略，可能有助于重建二者共生关系，希望对肾脏病的治疗提供进一步研究方向。     

Neonatal intestinal perforation in Hirschsprung's disease

Over a period of 18 years, 77 of 135 patients treated for Hirschsprung's disease (HD) presented in the neonatal period. Of these 77 patients, 8 had gastrointestinal (GI) perforations. Seven patients were born at full term and 1 at 32 weeks of gestation. Three patients had associated trisomy 21. The site of perforation included rectum in 1 patient, sigmoid in 1, descending colon in 1, transverse colon in 2, caecum in 2, and jejunum in 1. Perforations occurred in ganglionic bowel in 7 patients and in the aganglionic segment in 1. One patient died in the newborn period of overwhelming sepsis secondary to enterocolitis, and histology of the bowel confirmed HD. In 6 patients HD was confirmed on barium enema and suction rectal biopsy, and they subsequently underwent a definitive pull-through operation. The 1 patient in whom the initial barium enema was normal continued to suffer from constipation until the age of 7 years, when the diagnosis of HD was established. He then underwent a pull-through procedure with no further problems. An association between neonatal intestinal perforation and HD must therefore be recognised to avoid delay in the management.
