加味四君子汤对脾虚胃溃疡大鼠细胞外信号调节激酶信号传递分子的影响

目的探讨加味四君子汤治疗脾虚证的机理。方法运用HE染色显示胃组织结构,运用免疫组织化学方法显示下颌下腺EGF含量的变化,运用免疫印迹法显示胃黏膜ERK2含量的变化。结果经过加味四君子汤治疗后,脾虚胃溃疡大鼠下颌下腺颗粒曲管细胞内EGF阳性反映产物的含量减少,胃黏膜磷酸化的ERK2增加,胃溃疡愈合加快;而自然恢复组上述变化不明显。结论加味四君子汤可能通过影响分裂原激活的蛋白激酶信号传递途径而发挥治疗作用。     

栀子豉汤及拆方对六种人肠道菌的影响

目的研究栀子豉汤及栀子、淡豆豉对6种人肠道菌的影响。方法从特定人的粪便中分离培养肠杆菌、肠球菌、双歧杆菌、乳杆菌、产气荚膜梭菌和脆弱拟杆菌。分别将高、中、低浓度的栀子、淡豆豉及栀子豉汤药液加入选择性培养基中,以不加药液的培养基作为空白对照,将实验菌分别于厌氧或有氧条件下培养,计数菌落。结果不同浓度的栀子对肠杆菌的抑制率均为100.0%,淡豆豉在20%、50%、70%浓度分别使肠杆菌数量下调100.00%、53.83%和22.11%,而栀子豉汤可使肠杆菌数量维持在一定水平(104～106 CFU/g);两味药单独都表现了对肠球菌较强的抑制作用,而低、中浓度栀子豉汤则使肠球菌保持较稳定的数量;单味药及复方对产气荚膜梭菌和双歧杆菌敏感性较弱;栀子对脆弱拟杆菌抑制作用最强,而淡豆豉和栀子豉汤则可使其数量上调约20.00%;淡豆豉、栀子豉汤和高浓度栀子对乳杆菌非常敏感,低、中浓度栀子对乳杆菌数量仅有轻微下调作用。结论栀子豉汤比单独的栀子和淡豆豉更能维持肠道菌群的相对平衡。

化瘀解毒中药抑制梗阻性肾病巨噬细胞浸润减轻炎性损伤的作用

为观察化瘀解毒中药对梗阻性肾病巨噬细胞浸润的影响及作用机制。将48只健康雄性Wistar大鼠随机分为假手术组、模型组、依普利酮组、中药组,每组12只。除假手术组外,其余大鼠结扎单侧输尿管(UUO)复制肾间质纤维化动物模型。治疗组分别给以依普利酮(100 mg/kg/d加入饲料喂养)和化瘀解毒中药煎剂(14 g/kg/d灌胃)。10 d后摘取肾脏,观察大鼠肾脏组织病理改变。免疫组化法标记巨噬细胞浸润,免疫组化、Western Blot方法检测血清和糖皮质激素诱导蛋白激酶1(SGK-1)、单核细胞趋化蛋白-1(MCP-1)、白细胞介素-1(IL-1)、肿瘤坏死因子-α(TNF-α)的表达。肾脏病理显示,UUO组大鼠肾脏有明显的肾小管扩张及上皮细胞脱落,间质巨噬细胞浸润增多和细胞外基质(ECM)大量积聚,SGK-1、MCP-1、IL-1、TNF-α表达明显增强。化瘀解毒中药可明显减轻UUO大鼠肾脏巨噬细胞等炎性细胞浸润和ECM沉积,下调SGK-1、MCP-1、IL-1、TNF-α表达。以上结果说明化瘀解毒中药可抑制梗阻性肾病诱导的巨噬细胞浸润,减轻肾脏炎性损伤。

Inhibition of autophagy of Cajal mesenchymal cells by gavage of tong bian decoction based on the rat model of chronic transit constipation

The objective of this research was to study the effect of tong bian decoction on colon transport function of interstitial cells of Cajal (ICC) in chronic transit constipation (CTC) and the inhibition of autophagy of ICC, so as to achieve the free movement of the bowels. In this research, the experimental rats were divided into normal group (NG) and model group (MG) by random method, and the rat model of CTC was constructed by subdivision circulatory increasing operation gavage method of rhubarb. After the successful establishment of the model, the rats were divided into normal group, MG, tong bian decoction gavage group, mosapride group and normal recovery group. Then, rats in the NG and the MG were killed at the same time, and rats in the tong bian decoction gavage group, mosapride group and normal recovery group were killed at the same time. In this study, the transport function of colon of rats in each group was detected by activated carbon method, and the number of fecal residues in the colon was observed. The mRNA expression of c-kit gene in intestinal tissue of rat was detected by real-time quantitative polymerase chain reaction (RT-qPCR). In addition, the changes of ICC in rats treated with different drugs were detected by immunohistochemical method. The results revealed that in the tong bian decoction gavage group, the water content in the feces of rats was remarkably increased (P < 0.05), the amount of residual feces in the colon was remarkably reduced (P < 0.01), the percentage of carbon powder propulsion in small intestine was remarkably increased (P < 0.01), the staining area of ICC positive cells in colon tissue was remarkably increased (P < 0.05), and the expression of c-kit mRNA was remarkably increased (P < 0.01). It can be concluded that the tong bian decoction could effectively enhance the colon transport function in the rat model of CTC. This laxative mechanism promotes the regeneration and repair ability of ICC by inhibiting the autophagy of ICC, and provides power for the large intestine, so as to achieve the free movement of the bowels. Therefore, the results of this study have certain guiding meaning for the treatment of CTC with traditional Chinese medicine.
