BACKGROUND:Non-hematopoietic cell of mesenchymal stem cells (MSCs) or mesenchymal progenitor cells can differentiate into bone,cartilage,muscle,tendon,fat and bone marrow matrix in vivo and in vitro,thus becoming very valuable seed cells source in the field of tissue engineering.OBJECTIVE:To construct the tissue engineered tendon withⅠcollagen-polyglycolic acid as a scaffold and bone marrow MSCs as seed cells,and to observe the effect of tissue engineered tendon on repairing achilles tendon defects. DESIGN,TIME AND SETTING:Randomized controlled animal experiment was performed in the Xiangya Medical College of Central South University in 2003.MATERIALS:Healthy adult rabbits,irrespective of genders,weighing 1.5-2.5 kg,were offered by Animal Center of Xiangya Medical College,Central South University. Polyglycolic acid were purchased from Shandong Weigao Group Kanglida Medical Products Co.,Ltd (KLD Medical).SD rats were sourced from Department of Experimental Animals,Central South University.METHODS:Rabbit bone marrow was extracted to harvest MSCs with centrrfugation and adherence method,then bone marrow MSCs were isolated and amplified. Tail tendon was extracted from SD rats and prepared into type Ⅰ collagen solution,which was mixed and suture cultured with polyglycolic acid to construct collagen-polyglycolic acid scaffold. Other bone marrow MSCs,which were not induced in vitro,were incubated on collagen-polyglycolic acid scaffold to construct tissue engineered rabbit tendon models,with those without cells serving as controls. Thirty rabbit angle skins were cut open to separate tendon and produce a 3-cm defect. Fifteen rats in the experiment group was repaired with tissue engineered tendon,which was previously prepared with autologous bone marrow MSCs,while fifteen rats in the control group was given Ⅰ collagen-polyglycolic acid scaffold.MAIN OUTCOME MEASURES:Effect of tissue engineered tendon on repairing achilles tendon defects in rabbit.RESULTS:No matter whether contains autologous bone marrow MSCs,type I collagen-polyglycolic acid scaffold transplanted into animals exhibited column gel shape by general observation. At 4 weeks following transplantation,cordlike tissues were seen in the transplantation site,polyglycolic acid suture was degraded. At 8 weeks,the tissue engineered tendon tissues were cordlike shaped,white,lustrous and dense. They were well connected with receptor tendon tissues in the experiment group,without adhesion to peripheral tissues. In the control group,the tissues were slender and adhered to peripheral tissues. CONCLUSION:Using typeⅠ collagen-polyglycolic acid as a scaffold and bone marrow MSCs as seed cells,tissue engineered tendon can dramatically promote the repair of achilles tendon defects.

[Objective]To observe the clinical effect of the treatment with Acupuncture Baihui and Acupoint Injection of Baihui with the injection of Herba Erigerontis on the post cerebral infarction depression(PCID).[Methods] 260 PCID patients were randomly divided into 3 groups.The first group was the amitriptyline group (80 cases),the treatment with the basis of service on the cerebral infarction and plus oral amitriptyline.The second group was acupuncture group (80 cases),treated with the basis of service on the cerebral infarction and plus acupuncture Baihui treatment.The third group was acupuncture and acupoint injection group (100 cases),the treatment with the basis of service on the cerebral infarction and plus acupuncture and acupoint injection of Baihui with the injection of Herba Erigerontis.Observe the changes of HAMD,SDS,MeSSS,MMSE,Barthel Index (BI) score of 3 groups before and after treatment for 4 w,8 w,and assess the efficacy of the treatment.[Results] After treatment,HAMD,SDS,MeSSS,MMSE,Barthel Index (BI) score were significantly improved in 3 groups,among them,the acupuncture group and amitriptyline group were improved similar on the observation score,acupuncture and acupoint injection group was significantly better than acupuncture group and amitriptyline.[Conclusion] Initial examinations show that it can significantly relieve the symptoms of PCID depression by Baihui,and worthy of clinical application.

Objective To observe the effects of saponins of Panax notoginseng (PNS) on the brain energy metabolism and mitochondrial respiratory function of oxidative damaged rat model mimic to Alzheimer disease (AD). Methods Oxidative damaged rat model mimic AD (AD group) was established by injection of dihydroxy fumaric acid (DHF) and FeCl3 ADP into the left lateral ventricle of rats. The contents of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), and phosphate creatine (Pcr) in brain were determined by high performance liquid chromatography (HPLC). The mitochondrial functions (R3, R4, P/O, and OPR) were observed by Clark oxygen electrode method. The difference in the above parameters in rats in the control group (injection of saline), model group, and administration group (injection of PNS) was observed. Results The levels of ATP, Pcr, and R3, R4, P/O, and OPR of rats in AD group were significantly lower than those in the control group (0.9% NaCl instead of DHF FeCl3 ADP), but those in PNS group were higher than those in the AD group. Conclusion PNS can improve brain energy metabolism and mitochondrial function of oxidative damaged rats, suggesting that PNS could be used for the treatment of AD.

Objective To explore the effect of cilazapril on motor and cognitive function in hypertension with brain stroke. Method 42 hypertensive patients with stroke were divided into cilazapril treatment group(22 cases) and traditi onal treatment group (20 cases). The cilazapril group was treated with Inhibace 2.5 mg～5 mg daily. The traditional group was treated with nifedipine and/or di uretic. The blood pressure was measured twice a day during the treatment course. The activity of daily living (ADL), motor and cognitive function were assessed with Barthel index, Fugl-Meyer and MMSE assessment respectively before and 6 we eks after treatment. Results There were no difference between the two groups on blood pressure effectiveness, but blood pressure was more stable in the cilazapril gro up. Improvement of ADL and lower limb motor function in cilazapril treatment gro up were improved significantly than those of traditional treatment group(P<0.05). Although there was no difference between the two groups in the total value of cognitive function assessment, but the directional ability and memory function in group wa s higher than those in traditional group (P<0.05). Conclusion Cilazapril can decrease blood pressure steadily and can improve the activity of daily living and cognitive function in stroke patients.
