阿伐他汀联合丹参酮ⅡA磺酸钠对糖尿病肾病患者TGF-β1、CTGF表达水平的影响

[目的]探讨糖尿病肾病患者血清转化生长因子β1(TGF-β1)、结缔组织生长因子(CTGF)水平变化的临床意义及阿伐他汀联合丹参酮ⅡA磺酸钠注射液治疗该病的机制.[方法]将43例糖尿病患者根据尿白蛋白排泄率分为糖尿病无肾病组(19例)和糖尿病肾病组(24例),并纳入23例正常体检者进行对照.所有对象进入实验前及糖尿病肾病组治疗6周、12周和24周后取静脉血,用ELISA法测定血清TGF-β1、CTGF水平,并留24 h尿,用磺柳酸比浊法测定24 h尿蛋白含量.[结果]①正常对照组、糖尿病无肾病组及DN患者组血清TGF-β1、CTGF水平依次呈递增趋势;糖尿病无肾病组的尿蛋白含量与正常对照组差异性比较无显著性(P＞0.05),但其血清TGF-β1、CTGF水平却明显高于正常对照组(P＜0.01);DN患者组血清TGF-β1、CTGF水平、尿蛋白含量与正常对照组和糖尿病无肾病组差异性比较,亦均明显升高(P＜0.01).②经阿伐他汀联合丹参酮ⅡA磺酸钠治疗后,血清TGF-β1、CTGF水平与尿蛋白含量与治疗前比较明显降低(P＜0.01或P＜0.05),并逐渐趋于稳定.[结论]TGF-β1、CTGF在糖尿病肾病的发生发展中起重要作用,阿伐他汀联合丹参酮ⅡA磺酸钠治疗糖尿病肾病的机制可能与其抑制TGF-β1、CTGF的表达有关.     

基于金汁(粪菌移植)的历史及性味考探讨其应用前景

粪菌移植因其对难辨梭状芽孢杆菌感染、炎症性肠病等多种现代医学疾病的重要治疗价值,近30年来得到迅速发展。近年来不断有报道粪菌移植在肥胖、胰腺炎、糖尿病、肿瘤等领域的应用,但都是基于现代医学临床的偶然发现,并无非常清晰的理论指引。粪便治病起始作为一种中医的治疗手段,有明确的中医理论指导,在中医的辨证论治指导下,疗效显著。文章就古代及现代金汁的性味考、医学史、各自适应症等内容进行讨论,并探讨未来中西医两个领域的治疗展望。     

Executive function and health-related quality of life in pediatric epilepsy

Children and adolescents with epilepsy often show higher rates of executive functioning deficits and are at an increased risk of diminished health-related quality of life (HRQOL). The purpose of the current study was to determine the extent to which executive dysfunction predicts HRQOL in youth with epilepsy. Data included parental ratings on the Behavior Rating Inventory of Executive Function (BRIEF) and the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire for 130 children and adolescents with epilepsy (mean age = 11 years, 6 months; SD = 3 years, 6 months). Our results identified executive dysfunction in nearly half of the sample (49%). Moderate-to-large correlations were identified between the BRIEF and the QOLCE subscales of well-being, cognition, and behavior. The working memory subscale on the BRIEF emerged as the sole significant predictor of HRQOL. These results underscore the significant role of executive function in pediatric epilepsy. Proactive screening for executive dysfunction to identify those at risk of poor HRQOL is merited, and these results bring to question the potential role of behavioral interventions to improve HRQOL in pediatric epilepsy by specifically treating and/or accommodating for executive deficits.

Expression pattern of NMDA receptors reveals antiepileptic potential of apigenin 8-C-glucoside and chlorogenic acid in pilocarpine induced epileptic mice

The present study was aimed to evaluate the effect of apigenin 8-C-glucoside (Vitexin) and chlorogenic acid on epileptic mice induced by pilocarpine and explored its possible mechanisms. Intraperitonial administration of pilocarpine (85 mg/kg) induced seizure in mice was assessed by behavior observations, which is significantly (p > 0.05) reduced by apigenin 8-C-glucoside (AP8CG) (10 mg/kg) and chlorogenic acid (CA) (5 mg/kg), similar to diazepam. Seizure was accompanied by an imbalance in the levels of Gamma-aminobutyric acid (GABA) and glutamate in the pilocarpine administered group. Moreover, convulsion along with reduced acetylcholinesterase, increased monoamine oxidase and oxidative stress was observed in epileptic mice brain. AP8CG and CA significantly restored back to normal levels even at lower doses. Further, increased lipid peroxidation and nitrite content was also significantly attenuated by AP8CG and CA. However, CA was found to be more effective when compared to AP8CG. In addition, the mRNA expression of N-methyl-d-aspartate receptor (NMDAR), mGluR1 and mGlu5 was significantly (P ≤ 0.05) inhibited by AP8CG and CA in a lower dose. The mRNA expression of GRIK1 did not differ significantly in any of the group and showed a similar pattern of expression. Our result shows that AP8CG and CA selectively inhibit NMDAR, mGluR1 and mGlu5 expression. Modification in the provoked NMDAR calcium response coupled with neuronal death. Hence, these findings underline that the polyphenolics, AP8CG and CA have exerted antiepileptic and neuroprotective activity by suppressing glutamate receptors.
