A great progress has been achieved in research on repair of nerve functional recovery following spinal cord injury because of the development of nerve tissue engineering.As an important part of nerve tissue engineering,cell scaffold is divided into natural biomaterials,synthetic materials and composite materials.Besides,nanotechnology has been applied to study scaffolds.However,there are many problems in the application of cell scaffold and further study is needed.With the continued development of biotechnique and cross-correlated technique,the cell transplantation scaffold will make more effect on repair of spinal cord injury.

Introduction to the specific practice and policies of the hospital for academic promotions. The emphasis is placed on "quality priority" and "work performance", making an overall assessment of the applicants on their professional virtue, academic skills, research outcome and social services. Among all these indicators, appraisal of the clinical skills and teaching skills is prioritized,encouraging the creativity and incentives of clinicians for clinical and teaching work.

In Order to resolve the failure of PCR to amplif y 8-receptor, the influence of PCR amplification the different concentration of DMSO was observed． The result show that the centain concertation of DMSO can greatly enhance the specificity and efficiency of PCR amplification

To study the determination method of cholesterol in human serum by Coulometric titration. METHODS: The titration was carried out in an electrolytic solution containing 1 mol.L-1 potassium bromide and glacial acetic acid (1∶3). Bromine was electrogenerated at the anode and cholesterol reacted with bromine with a value of reactional electrons (n) as 2. RESULTS: The ranges of recovery for 0.115 mg to 0.459 mg of cholesterol were from 93.9% to 105%, and the average recovery was 100.3%. The relative standard deviation in all applied analysis was less than 1.5%. The accuracy of the method was also assessed in comparison with the results obtained by the enzymatic method used clinically. CONCLUSION: The method proposed is simple, rapid and accurate, and is suitable for the determination of cholesterol in human serum samples.

Objective: To determine the content ursodesoxycholic acid of Compound Capsule of Bear Gall thylic. Methods: TLCS method was used. Results: Owing to improving the method on the base of original Criterion, the determination result is more similar to the true value.

Moyamoya disease is an uncommon cerebral disease, but its morbidity is relatively high in East Asian populations. Ivy sign refers to the dot or linear high signal phenomenon in MRI T1 enhanced sequence in patients with moyamoya disease. It mainly distributes in the pial surface of cerebral cortex or within subarachnoid space. It has important significance for diagnosing moyamoya disease and assessing the staging and prognosis of moyamoya disease. This article briefly reviews this imaging finding and its significance.

In view of the deficiencies of both Qi and Yin in most cases of this tumor, Jinfukang oral solution (JFK). a remedy mainly for benefiting Qi and nourishing -yin. was formulated. 96 cases were treated with one case of CR. 8 cases PR, 52 NC. the rate of PR + NC being 63. 5%. Another 52 cases were treated with chemotherapy +JFK. with 11 cases of PR, 26 cases NC, the rate of PR + NC being 71. 2%. While 25 cases were treated by chemotherapy alone, the cases of PR was 4; NC 26. the rate of PR + NC being 60. 0%, This demonstrated that the effect of JFK and JFK + chemotherapy were all superior to effect of chemotherapy alone. For 1 - and 2 - year survival rates, the JFK group was 67. 3% and 66. 7% respectively, whereas that of JFK + chemotherapy. 67. 3% and 66. 7%. For the chemotherapy group , 1 - year survival rate was 40. 3%, with no survivals within 2 years. For symptom improvement, body weight gaining, and health condition (KPS evaluation) after treatment, the JFK and JFK + chemotherapy groups were, again, superior to the chemotherapy group. The Immunity indices and blood picture in JFK group after treatment were markedly improved as compared with those before treatment, but, those in the chemotherapy group were decreased, while those of the JFK + chemotherapy group remained unchanged.

Objective To investigate the imaging feature of Chinese familial BCS, and to evaluate the efficacy of interventional treatment for Chinese familial BCS. Methods Angiography was taken in 4 familial BCS patients(from families A and B), and PTA was attempted in 2 of 4 patients, stents were placed in another 2 patients. Results Sisters in family A and sisters in family B had membranous obstruction of the inferior vena cava(MOVC) and segmental obstruction of the inferior vena cava(SOVC), respectively. PTA was attempted in younger sisters of the two families, stent was implanted in elder sisters of the two families. Patency of inferior vena cava and clinical symptom improvement were noted in 4 patients after interventional treatment. Restenosis was detected by angiography in sisters of family A after follow up 2 years later, and stenting was performed in the elder sister, PTA was performed in the younger sister once again. The elder sister was dead after the second stenting, and the younger sister had no symptom up to now. Sisters in family B had no restenosis after 4 years′ follow up. Conclusion 1.Lesion types of Chinese familial BCS were varied. 2.Vena cava thrombosis is the etiology of Chinese familial BCS .3.PTA, stenting and long time anticoagulation treatment may be effective methods in the treatment of familial BCS.

Objective To discuss the clinical characteristics of Hashimoto's thyroiditis accompanying with thyroid cancer. Methods Clinical data of 98 cases Hashimoto's thyroiditis accompanying with thyroid cancer were retrospectively reviewed. Results 2 cases underwent lateral thyroid lobectomy and isthmus resection. 58 cases underwent bilateral thyroid lobectomy. 35 cases underwent central lymph node dissection, with 15 cases of lymph node positive. 3 cases underwent modified radical dissection of cervical lymph nodes and all of them were proved to be lymph node positive. Metastasis rate is 25.0% and 52. 2% respectively for tumors whose diameter was less than 1 cm and greater than 1 cm. The difference has no statistic significance. Conclusions Hashimoto's thyroiditis usually accompany with thyroid papillary carcinoma and cervical lymph node metastasis can occur even if it's microcarcinoma. Lymph node metastasis rate increases with increasement of the tumor's diameter. Total thyroidectomy should be performed for Hashimoto's thyroiditis concomitant with thyroid cancer. And if necessary,lymph node dissection should be extended to the central region and lateral neck area.
