目的 探讨川芎嗪对链脲佐菌素(STZ)诱导2型糖尿病大鼠肾病的治疗作用及机制。方法 SD大鼠50只,随机分为正常组和模型组。除正常组外,其余大鼠均给予高脂-高糖饲料喂养4周,再给予链脲佐菌素(40 mg/kg,ip),72 h后测定空腹血糖,将血糖值高于16.67 mmol/L的大鼠随机分成4个组即模型组,二甲双胍阳性组(250 mg/kg),川芎嗪低、高剂量组(80、160 mg/kg),连续给予相应试药8周。其中正常组和模型组的大鼠均给予同等量蒸馏水灌胃。实验结束时,测定大鼠血糖、尿蛋白、血尿素氮和血肌酐含量;免疫组化法测定大鼠肾组织TLR4和caspase3蛋白表达。光镜下观察肾脏病理学变化。结果 与模型组比较,二甲双胍组和川芎嗪高剂量组给药8周后,大鼠动态空腹血糖均能明显降低(P<0.05),大鼠动态尿蛋白显著性降低(P<0.01,P<0.05); 二甲双胍和高剂量组TLR4和caspase3蛋白表达明显低于模型组(P<0.05);肾脏组织病理性损伤明显减轻。结论 川芎嗪对STZ诱导2型糖尿病大鼠肾病具有保护作用,其机制可能与下调TLR4表达作用有关。

Objective To investigate the therapeutic effects and mechanisms of tetramethylpyrazine (TMP) on streptozocin(STZ)-induced-nephropathy in type 2 diabetic rats. Methods 50 SD rats were randomly divided into normal group(n=10) and model group(n=40). The model rats were fed on high fat and sugar diets for 4 weeks, then given STZ(40 mg/kg,ip). After 72 hours, the fasting blood glucose (FBG) was measured. Rats with high FBG above 16.67mmol/L were randomly divided into four groups: model, metformin(Met, 250 mg/kg)and TMP (80 mg/kg, 160 mg/kg) groups for treating 8 weeks, and both the control and model groups were given equals distilled water by intragastric administration. At the end of the experiment, blood glucose, urine protein, blood urea nitrogen and creatinine were measured. The expression of TLR4 and caspase3 protein in kidney tissue of rats was determined by immunohistochemistry. Pathological changes of kidney were observed under light microscope. Results Compared with the model group, metformin and high dose of TMP administered after 8 weeks, rats can significantly reduce the dynamic fasting blood glucose(P<0.05). Urinary protein excretion of total dynamic decreased significantly (P<0.01, P<0.05); the protein expression of TLR4 and caspase3 in the metformin group and high dose group was significantly lower than that in the model group (P<0.05); kidney tissue pathological damage was significantly reduced. Conclusion TMP has a protective effect on STZ induced nephropathy in type 2 diabetic rats, and its mechanism may be related to the down-regulation of TLR4 expression.

Objective To compare the clinical effects of uniportal video-assisted thoracic surgery (VATS), single utility port VATS and 3-portal VATS lobectomy for patients with early stage non-small cell lung cancer. Methods Patients were divided into uniportal VATS lobectomy group(n=38), single utility port VATS lobectomy group(n=42) and 3-portal VATS lobectomy group (n=45). The surgical results and complication rates were observed. Results All patients completed the operation successfully, no one was changed to open operation. Operation time in uniportal VATS lobectomy group were longer than single utility port VATS lobectomy group and 3-portal VATS lobectomy group(P＜0. 05). There were no significant differences in intraoperative blood loss, number of lymph node dissection, the amount and time of postoperative extubation, and the incidence of postoperative complications(P＞0. 05). Post-operative pain score were higher in 3-portal VATS lobectomy group than in uniportal VATS lobectomy group and single utility port VATS lobectomy group (P＜0. 05). Conclusion Uniportal VATS lobectomy and single utility port VATS lobectomy can replace the 3-portal VATS lobectomy in treatment of early NSCLC, because of the faster postoperative recovery and curative effect. Uniportal VATS lobectomy requires special equipment and more operation skills, as there is no breakthrough in the equipment, single utility port VATS lobectomy may still be used as the first choice for treatment of early NSCLC.

Objective To investigate the expressions and clinical significances of atrial brain natriuretic peptide precursor (PRO-BNP), homocysteine (Hcy) and erythrocyte sedimentation rate (ESR) in patients with unstable angina pectoris associated by Left ventricular systolic insufficiency. Methods A total of 130 patients with simple unstable angina pectoris and another 130 patients with unstable angina pectoris associated by left ventricular systolic insufficiency treated during January 2015 and October 2016 were selected as group A and group B respectively,and at the same period,130 healthy persons taking medical examination were selected as the control froup (group C). Serum levels of PRO-BNP,Hcy and ESR were detected in three groups,and the correlation between serums PRO-BNP,Hcy and ESR and left ventricular ejection fraction (LVEF) in group B were analyzed. Results Serum levels of in group A and B were significantly higher than those in group C,and the levels in group B were significantly higher than those in group A. In group B,serum levels of PRO-BNP,Hcy and ESR were significantly increased with rising cardiac function classification. Serum levels of PRO-BNP,Hcy and ESR in group B were negatively correlated with LVEF,but serum levels of Hcy and ESR were positively correlated with PRO-BNP level. Conclusion Serum levels of PRO-BNP,Hcy and ESR in group A and B are significantly correlated with cardiac function in patients with unstable angina pectoris associated by left ventricular systolic insufficiency,so the levels may be used as important indexes for evaluating the severity and prognosis of with unstable angina pectoris associated by left ventricular systolic insufficiency.
