Aim To observe the effects of tetrahydro-biopterin ( BH4 ) on nitric oxide ( NO ) production in the kidney of type 2 diabetic nephropathy ( DN) mice, and to find a new target for the treatment of type 2 DN. Methods The 12 week-old db/db mice developed in-to DN phase were divided into 2 groups:DAHP group, subjected to intraperitoneal injection of 150 mg·kg-1 DAHP (n=8);DN group, subjected to intraperitone-al injection of same dose of normal saline containing 5% DMSO ( n = 6 ) . The age-matched db/m mice ( NS group) were subjected to intraperitoneal injection of same dose of normal saline containing 5% DMSO ( n =6 ) . Three groups of mice were treated for 7 days. Then the fasting blood-glucose, serum creatinine, u-rine protein and activity of iNOS were determined by chemical colorimetry. And the iNOS protein in renal cortex was determined by immunohistochemisty and western blot, respectively. BH4 was measured by HPLC method. NO level was determined by Griess method. Results The levels of fasting blood-glucose, serum creatinine, 24h urine volume, 24h urine pro-tein, BH4 , iNOS and NO in DN group were signifi-cantly higher than those in NS group;The levels of ser-um creatinine, urine volume, urine protein, BH4 , iN-OS and NO in DAHP group were significantly lower than those in DN group. Conclusion In the kidney of type 2 DN mice, the increased BH4 contributes to over-production of NO by the increased iNOS expression, and resultes in the increase of urine volume and urine protein.

AIM: To investigate the effect of cobalt chloride (CoCl2) on the apoptosis of neural stem cells (NSCs) and the expression of microRNA-26a (miR-26a) in vitro, and to explore the mechanisms of NSC apoptosis in-duced by CoCl 2 .METHODS:NSCs were exposed to CoCl 2 at different doses (200~600μmol/L) for 24 h.The cell via-bility and apoptosis were measured by CCK-8 assay and TUNEL method.The expression of miR-26a-3p, miR-26a-5p, GSK-3β, caspase-3, Bcl-2 and Bax was examined by real-time PCR.The protein levels of Bcl-2 and Bax were detected by Western blotting .RESULTS: The cell viability was inhibited and the apoptosis of NSCs was increased significantly by CoCl2 in a dose-dependent manner (P<0.05).CoCl2 at concentration of 400μmol/L for 24 h was used to induce apopto-sis and the expression of miR-26a was down-regulated compared with control (P<0.05).Exposure to CoCl2 at concentra-tion of 400μmol/L up-regulated the expression of GSK-3β, caspase-3 and Bax , down-regulated the expression of Bcl-2 and Bcl-2/Bax (P<0.05).CONCLUSION:CoCl2 at concentration of 400μmol/L induces the apoptosis of NSCs obviously . CoCl2 may induce the NSC apoptosis by mitochondrial apoptotic pathway .Declining miR-26a may be related to NSC apopto-sis.

Objective To investigate the characteristics of myocardial injury and its underlying mechanism in rats resuscitated from cardiac arrest. Methods Forty-two male Wistar rats were randomly(random number) assigned into the post-resuscitation (PR) 4 h, PR 24 h, PR 48 h, and sham groups. Ventricular fibrillation was induced by transcutaneous electrical epicardium stimulation and untreated for 6 min, followed by cardiopulmonary resuscitation (CPR). Myocardial function, glucose metabolism, myocardial ultrastructure, the status of mitochondrial permeability transition pore (MPTP) and mitochondrial membrane potential (MMP) were evaluated at different time points. Results Myocardial dysfunction was found at 4 h after restoration of spontaneous circulation (ROSC). The ejection fraction and cardiac output were decreased (all P<0.01), the diastole left ventricular posterior wall became thicker (P<0.01), and the end-diastolic volume was reduced (P<0.05). However, cardiac function was recovered almost completely at 48 h after ROSC. The PR 4 h group had a higher SUVmax, a more obvious decreased absorbance, and a lower MMP than the sham group (all P<0.01), but no statistically significant differences were noted between the PR 48 h group and the sham group (P>0.05). At 4 h and 24 h after ROSC, the mitochondria was swollen and the mitochondrial crista was sparse, but the myocardial ultrastructure was complete. Conclusions Post resuscitation myocardial dysfunction occurs after ROSC and the myocardial dysfunction is completely reversible at 48 h after ROSC, which may be related to the reversibility of myocardial injury and the gradual recovery of mitochondrial structure and function.
