中药何首乌饮对大鼠卵巢颗粒细胞凋亡相关蛋白bcl-2,bax表达的影响

目的通过测定不同剂量的中药何首乌饮含药血清作用后的大鼠卵巢颗粒细胞的凋亡相关基因bcl-2、bax的蛋白表达及caspase-3活性,探讨何首乌饮对卵巢自身功能的影响。方法制备排卵前卵巢模型,收集颗粒细胞分别与雌性SD幼鼠空白血清及含不同剂量何首乌饮的药物血清在体外共同培养,Western blotting检测GC内凋亡相关基因bcl-2、bax的蛋白表达情况;分光光度法检测颗粒细胞内caspase-3活性。结果何首乌饮含药血清可上调颗粒细胞bcl-2蛋白表达,下调bax蛋白表达,中、高剂量组何首乌饮含药血清与对照组比较,可明显上调bcl-2蛋白表达(P均<0.01),中、高剂量组何首乌饮含药血清与对照组比较,明显下调bax蛋白表达(P均<0.01)。何首乌饮含药血清可下调颗粒细胞caspase-3活性,中、高剂量何首乌饮含药血清组与对照组比较有显著性差异(P均<0.01)。结论何首乌饮增加GC内凋亡抑制蛋白bcl-2表达及减少凋亡促进蛋白bax表达的作用,可能是其抑制GC凋亡,防止卵泡闭锁的作用途径之一;同时何首乌饮可能是在凋亡的较早阶段,通过阻断caspase-3的级联裂解即可开始起效,而发挥凋亡抑制作用。     

A Case of Secondary Glaucoma due to Bilateral Anterior Chamber Shallowing Caused by Marfan′s Syndrome

Purpose:To report the clinical manifestations and treatment of a case of secondary glaucoma evolving from bilateral anterior chamber flattening caused by Marfan′s syndrome. Methods:The ophthalmic and systemic features,B-scan and UBM characteristics were recorded.Therapy and efficacy were analyzed. Results:Marfans syndrome,in this case,caused bilateral iris-lens diaphragm anterior dislocation,anterior chamber flattening, pupillary block, angle closure,and finally resulted in persistent increased intraocular pressure (IOP). After undergoing pars plana vitrectomy and lensectomy combined with anterior chamber reformation, the visual acuity of the patient’s right eye increased from 6/150 to 6/7.5.(best-corrected) and that of the left eye was improved from 6/100 to 6/10 (best-corrected). The IOP of the right eye fell to 18 mm Hg, and the left eye to 12 mm Hg. Conclusion:Marfan′s syndrome can cause bilateral anterior chambers flattening,and induce secondary angle closure glaucoma.Combined pars plana vitrectomy, lensectomy and anterior chamberplasty can re-form the anterior chamber, control IOP and maintain visual function.     

Haploidentical hematopoietic stem cell transplantation may improve long-term survival for children with high-risk T-cell acute lymphoblastic leukemia in first complete remission

Background: The role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with high-risk (HR) T-cell acute lymphoblastic leukemia (T-ALL) in first complete remission (CR1) is still under evaluation. Moreover, relapse is the main factor affecting survival. This study aimed to explore the effect of allo-HSCT (especially haploidentical HSCT [haplo-HSCT]) on improving survival and reducing relapse for HR childhood T-ALL in CR1 and the prognostic factors of childhood T-ALL in...

Non-diabetic urine glucose in idiopathic membranous nephropathy

This study aims to analyze the characteristics of idiopathic membranous nephropathy (iMN) with nondiabetic urine glucose during the follow-up. We retrospectively analyzed the data of 1313 patients who were diagnosed iMN. The prevalence of nondiabetic urine glucose during follow-up was 10.89%. There were significant differences between the patients with nondiabetic urine glucose and those without urine glucose in gender, hypertension ratio, proteinuria, N-acetyl-β-glucosaminidase, retinol binding protein, serum albumin, serum creatinine (Scr), cholesterol, triglyceride and positive anti-phospholipase A2 receptor antibody ratio, glomerular sclerosis ratio, acute and chronic tubular injury lesion at baseline. To exclude the influence of the baseline proteinuria and Scr, case control sampling of urine glucose negative patients was applied according to gender, baseline proteinuria and Scr. The proteinuria nonremission (NR) ratio was 45.83 versus 12.50% of the urine glucose positive group and case control group. Partial remission (PR) ratio of the two groups was 36.46 versus 23.96% and complete remission (CR) ratio was 19.79% versus 63.54%, respectively. Patients with urine glucose had higher risk of 50% estimated glomerular filtration rate (eGFR) reduction. Cox regression showed that urine glucose and baseline Scr were risk factors of 50% reduction of eGFR. Urine glucose remission ratio of the patients with proteinuria NR, PR, and CR was 13.33, 56.25, and 94.73% (p < 0.005). Patients who got urine glucose remission also had better renal survival. In conclusion, non-diabetic urine glucose was closely related to proteinuria. It could be applied as a tubular injury marker to predict renal function.
