1.Progress in the scaffolds for spinal cell transplantation
Chinese Journal of Tissue Engineering Research 2007;0(41):-
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.

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.

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.

Objective To study the influence of aldehydes and tannic acid on soft capsules, approach how to prevent soft capsules from delayed disintegration. Methods Add aldehydes and tannic acid to soft capsules material ingredient, to proceed accelerating stability trial and test the disintegration time. Result Little increase of aldehydes amount had great effect on the disintegration time of soft capsules, different aldehydes and tannic acid had different effect on the disintegration time, adding some organic acid such as fumaric acid to the material would improve disintegrating property. Conclusion The amount of aldehydes and tannic acid contained in the material and ingredient should be controlled strictly when prepare soft capsules so that the disintegration time of capsules could be complying with the Pharmacopeia.

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.

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.
