麻黄加术汤对大鼠类风湿性关节炎模型作用机制的研究

目的探讨麻黄加术汤对类风湿性关节炎的作用机制。方法运用Ⅱ型胶原法建立Wistar大鼠类风湿性关节炎模型,采用麻黄加术汤给予干预,以甲氨喋呤片为阳性对照药。将大鼠随机分为空白组、模型组、甲氨喋呤组、麻黄加术汤组。检测大鼠血清炎性细胞因子IL-1β、TNF-α浓度,观察大鼠膝关节滑膜组织病理改变。结果麻黄加术汤可显著降低大鼠血清炎性细胞因子IL-1β、TNF-α的含量,差异具有统计学意义(P<0.01),对CIA大鼠滑膜组织的炎性细胞浸润、纤维组织增生和巨噬样A型细胞有明显抑制作用,差异具有统计学意义(P<0.01)。结论麻黄加术汤治疗类风湿性关节炎的机制可能与降低炎性因子IL-1β、TNF-α的水平,抑制炎性细胞浸润、纤维组织增生和巨噬样A型细胞增生有关。 更多还原

[目的]为区分不同产地大黄药材的质量及鉴别提供依据。[方法]利用x一射线衍射分析法,得到青海不同产区大黄的X-射线衍射图谱,并对其进行相似性分析。[结果]不同产区的大黄中各化学成份的含量有差异,但其衍射图谱及衍射峰值具有一定的指纹特征。[结论]X-射线衍射法是鉴别不同产区的大黄及其他中药材的一种快捷有效的方法。     

中药滋肾养膜方对宫腔粘连内膜修复的临床研究

目的 通过观察中药滋肾养膜方联合宫腔镜技术对宫腔粘连患者内膜修复的影响,探讨中药治疗宫腔粘连的临床疗效。方法 收集观察就诊于“尤昭玲教授妇科工作室”和长沙市第一医院妇科的100例宫腔粘连患者的临床病历资料,随机分为两组,对照组50例宫腔镜技术加西药（雌孕激素序贯疗法）,试验组50例在对照组基础上配合中药滋肾养膜方,连续3个疗程。观测两组患者治疗疗效,月经量的恢复、中医证候的改善情况和对子宫内膜的影响。结果（1）试验组和对照组在年龄、病程长短、宫腔操作次数、流产次数和治疗前症候的比较,差异无统计学意义,具有齐同可比性;（2）试验组患者经治疗综合疗效总有效率88%要高于对照治疗组（84%）,但两组差异经Radit分析,差异无统计学意义;（3）两组经治疗临床症状明显改善,差异具有统计学意义（P<0.05）;（4）两组中医证候治疗后主要症状变化比较,试验组在改善经前乳胀、神疲乏力、失眠健忘、面色萎黄或晦暗方面,明显优于对照组且有统计学意义（P<0.05）,在其余症状、体征等方面,两组无统计学意义（P>0.05）;（5）对两组患者治疗后月经情况：月经周期、经期、经量、月经色质均明显改善;（6）两组治疗前后子宫内膜厚度比较,治疗后两组子宫内膜厚度均较治疗前增厚,有统计学意义（P<0.05）,试验组与对照组组间比较,试验组增厚程度大于对照组,但差异无统计学意义（P>0.05）。结论 中药滋肾养膜方联合宫腔镜技术和西药治疗对宫腔粘连患者内膜修复效果好,临床疗效确切,可明显增加患者的月经量并且改善患者中医临床症状,值得推广。

四君子汤对脾虚大鼠肝脏结构与功能的影响

健康SD大鼠随机分为对照组、脾虚组、中药组（四君子汤治疗）。利血平诱导和建立大鼠脾虚模型,四君子汤进行治疗。组织学观察可见,脾虚大鼠肝细胞体积减小,核质比升高,脂肪空泡增多,肝索形态不可见;经四君子汤治疗后,肝细胞、肝索形态恢复,脂肪泡显著减少,且四君子汤有促进肝细胞增生作用。脾虚大鼠血清肝细胞损伤标志性指标ALT含量显著升高（P〈0．05）;AST显著降低（P〈0．05）,脾虚情况下肝细胞损伤、线粒体功能下降;ALP含量显著降低（P〈0．05）,肝脏合成ALP减少;GGT含量显著升高（P〈0．05）,与肝细胞膜及肝内胆管上皮损伤相关。脾虚大鼠血清CHO,IBIL与TBA含量显著升高（P〈0．05）,肝脏摄取转化和排泄胆固醇、胆红素和胆汁酸能力下降。由此可见,脾虚状态下大鼠肝脏受损,代谢胆红素及胆汁酸功能下降,脾虚黄疸为肝细胞性黄疸;四君子汤对脾虚大鼠肝脏结构改变有修复作用,一定程度回调肝功能指标,并促进肝脏代谢胆红素与胆汁酸能力恢复正常。     

Effect of Xuefuzhuyu decoction on cardiomyopathy in type 2 diabetic rats

AIM: To observe the pathologic changes of cardiomyopathy in type 2 diabetic rats and the therapeutic effect of Xuefuzhuyu decoction.METHODS: The diabetic model was established by feeding the animals with high-fat diet and injecting a middle dose of streptozotocin (50 mg/kg) intraperitoneally in 42 Wistar male rats. After 8 weeks, the damage of the heart in the model animals was detected by electrocardiogram and echocardiography, and the serum level of glucose, total cholesterol and triglyceride were determined by the methods of clinical chemistry. The content of collagen was quantified by Masson staining. The apoptosis of cardiomyocytes was measured by TUNEL apoptosis kit. The structures of myocardial damage were observed under light and electronic microscopes.RESULTS: (1) Compared with normal group at the same time points, the contents of serum glucose, triglyceride and cholesterol in model group increased (P<0.05). At the 11th and 14th weeks, the thickness of LVDS was significantly increased (P<0.01), the structure of myocardial tissues was severely damaged and collagen fiber content increased obviously (P<0.01). The cell apoptosis was also increased. (2) Compared with control group at the same time points, the contents of serum glucose, cholesterol and triglyceride in Xuefuzhuyu decoction group significantly decreased (P<0.05). The thickness of LVDS at the 11th and 14th weeks was decreased (P<0.05) and LVM at the 14th week became significantly thinner (P<0.01). The damage of the myocardium and subcellular structure was slighter and the content of collagen was lower than that in control group (P<0.05). The cell apoptosis was also attenuated.CONCLUSION: The levels of blood glucose, total cholesterol and triglyceride and the content of collagen fibers increase when diabetic cardiomyopathy develops, with more cell apoptosis and severe damage in the cardiac structure. Xuefuzhuyu decoction decreases the level of blood lipid in diabetic cardiomyopathy, alleviates the pathological changes of myocardial fibrosis and delays the progression of diabetic cardiomyopathy.
