Objective To investigate the expression of anionic site in adriamycin-induced nephropathy (AN) rats, and to further explore the effects of Qufengtongluo Recipe on charge barrier in glomerulus in AN rats. Methods Adriamycin nephropathy was induced by a single tail intravenous injection of adriamycin. Totally 80 rats were randomly divided into normal control group and nephropathy model group. Three weeks later, the nephropathy model was established, and 50 AN rats were randomly divided into five groups: nephropathy model group (B, n=10), Qufeng group (C, n=10), prednisone and Qufeng group (D, n=10), prednisone group (E, n=10) and benazepri group (F, n=10), and they were treated respectively. With treatment being given respectively, renal tissue samples in each group were collected at week 3 and 7, respectively. The ultrastructure and expression of anionic site were examined by electron microscope observation. Results ① After adriamycin injection, a significant increase of the 24-hour urinary protein was observed at week 3 (P<0.01). In AN rats, serum albumin was decreased (P<0.01) while serum TCH and TG were increased (P<0.01). ② In AN rats the diffuse fusion and effacement of foot processes and decrease of anionic sites in GBM were observed at week 3. ③ At week 7, the average intensity of AS dramatically increased in C and E groups (P<0.01) compared with that in nephropathy model group. Conclusion The abnormal expression of AS is the important mechanism that leads to the occurrence and development of proteinuria in AN rats. It is possible that Qufengtongluo Recipe has effects on nephrotic syndrome through altering the charge barrier in GBM in glomerulus.

Post-stroke aphasia is an acquired language disorder caused by stroke.It impaired the quality of life of patients and brought a heavy burden to family and the society.Unfortunately,the highly variable predictive factors make the prognosis of aphasia recovery difficult.Much of the researches indicated that the post-stroke aphasia recovery is associated with the patient-related and stroke-related factors.We searched the recent advances on the influence of patient-related factors and stroke-related factors on aphasia recovery.It showed that patient-related factors have no obvious effect on predicting aphasia recovery while the lesion (stroke)-related factors appeared close correlation with post-stroke aphasia recovery.The clinicians should pay more attention on lesion (stroke)-related factors when evaluate the outcome and give the intervention measures.

As the human population ages and the life expectancy increases,tendon injuries will become more prevalent,especially among young individuals.Though the traditional operative therapy for tendon lesion can relieve the suffering of patients,the functional reconstruction is usually not optimistic.Tissue engineering is an advancing field,as the technology of construction in vitro and application in vivo matures,that can provide a more promising approach for tendon repair without tendon autograft.Challenges and future directions in the field of tendon tissue engineering focusing on four key parameters:seed cells,novel scaffolds,and mechanical stimulation.Recently,the discovery of TDSCs (tendon-derived stem cells) provides new ideas for the selection of seed cells and effect of mechanical stimulation on the tendon tissue engineering has become a hot spot.This article provides a review of recent progress in research about seed cells,scaffolds and mechanical stimulation for tendon engineering,and also speculates on the development in the future.

Objective To explore the protective role of PR-39 on the ischemia reperfusion injury renal tissue of rats.Methods 60 male SD rats were enrolled and randomly divided into experimental KP group and negative control KE group.The rats orthotopic renal transplantation model were established.The recombinant adenoviral vectors containing promoter KSP and PR-39 gene (KP) or none (KE) were injected via renal artery.HE staining,immunohistochemistry and TUNEL staining were performed on the rats' renal tissues at 2 days after IRI modeling,and the renal tubular interstitial injury score and peritublar capillary rarefaction was also evaluated.The renal function related factors of rats was monitored before and after IRI,and the blood urea nitrogen and creatinine level was also compared between KP and KE groups.Results Blood urea and creatinine concentration was increased,part of glomerular and tubular injury in renal tissue were also visible in rats underwent renal IRI,which proved the rat orthotopic renal transplantation model were successfully estabilshed.PR-39 gene specifically expressed in renal interstitial tissue,but not in glomerular.The degree of kidney tublar injury and the number of apoptotic cells were lower in KP groups by comparing with negative control KE groups.Renal tubular injury was significantly decreased in group KP than in group KE.Peritubular capillary rarefaction index is smaller in KP than in KE group.The blood urea nitrogen and creatinine level in KP group were significantly lower than those in KE group,and the renal function were also recovered more quickly.Conclusion The specific expressed PR-39 in renal interstitial and tubule,can inhibit the apoptosis of renal tubular epithelial cells and promote the angiogenesis of peritubular capillary,so as to exert its protective role on IRI renal tissue.
