Gene therapy of spinal cord injury (SCI) is the most promising method compared with the others, because it doesn't involve the problems of resource and higher exclusion which respectively exists in fetal nerve transplantation and peripheral nerve transplantation. There are two ways of gene therapy to be chosen: one is to transfer objective genes to the target-cells in vivo directly; the other is to transfer objective genes to one proper kind of transplantable cells firstly, then graft the highest expressing cells to the target-cells in vivo. To realize the transfer of genes to cells, two measures are used in common: physical or chemical measure such as micro infection et al and biochemical measure i. e. gene modified defective virus. Although there are some questions unresolved in this field, the clinical value of gene therapy of SCI in the future is depended.

Objective To assess training programs from trainees of Shanghai General Practice Teacher Training Center for further improvement.Methods Total 171 trainees attending the GP teacher training program in April,2012 were selected for survey.A self-designed questionnaires were adopted in the survey.The rationality of the curriculum and training contents in the program were analyzed.Results Among 170 trainees who answered the questionnaires,86 of them (51％) considered the training curriculum as very appropriate,76 of them (9％) considered as appropriate; 97 of them (57％) thought the training forms as very vivid,65 of them (38％) thought as vivid.The overall evaluation score for teachers was 4.64.Ninety three of the 170 trainees (55％) expressed a great willingness for training,70 (41％) expressed as willingness.Among 170 trainees 156 (92％) preferred to learn new advances in medicine,111 (65％) preferred to learn teaching skills and theories in general practice.Thirty two trainees (19％) considered that the contents of training met the trainees' needs completely,129 (76％)considered that most contents of training met the trainees' needs.Eighty two (48％) considered that they gained a lot after the training,80 (47％) considered that they gained fairly.The survey showed that 147 (86％) believed the training had broadened their minds,104 (61％) believed the training had increased their capabilities of clinical diagnosis and treatment; 53 (31％) thought the training helped raise their theoretical level.Eighty seven (51％) were very satisfied and 75 (44％) were comparatively satisfied with the training in overall evaluation.Conclusion The training program provided by Shanghai General Practice Teacher Training Center is basically satisfactory and trainees are benefited from the training considerably.

Objective To explore the effects of low energy intravenous He-Ne laser irradiation of blood (ILIB) on cell proliferation, apoptosis and genotoxicity of lymphocytes in patients with cerebral infarction (CI). Methods The lymphocytes in peripheral blood in patients with CI were sampled before and after treatment and cultured, and then, some parameters such as the mitosis index (MI), cell cyclical kinetics index (CCKI), sister chromatid exchanges frequencies (SCEF) and apoptosis were analyzed in order to explore the effects of ILIB on lymphocytes. Results The proliferative activities of lymphocytes were significantly increased by ILIB (P0.05). After ILIB, the rate of apoptosis in patients with CI was significantly increased when compared with that before treatment and that of the control group, as revealed by flow cytometry (FCM) (P

Objective To investigate the role of IP-10 in the pathogenesis of ankylosing spondylitis (AS). Methods The peripheral blood monocytic cells (PBMC) were collected from 39 AS patients, and the mRNA expression of IP-10, IFN-? and IL-4 were measured by semi-quantitive RT-PCR with G3PDH as the internal control. Results The mRNA expression levels of IP-10, IFN-? and IL-4 as well as the rate of IFN-?/IL-4 were elevated in the PBMC of AS patients compared with the healthy controls (P

Objective To determine the potential deficiency due to lack of anaerobic culture and evaluate the effect to reduce adverse reaction associated to transfusion-translated bacterial infection.Methods The result of 9 758 units of apheresis platelet concentrates (PCs)detected with automated microbial detection system were reviewed and the medical records of the patients that received the contaminated PCs were followed.Results The confirmed positive rates by aerobic and anaerobic cultures were 0.06％ (6/9 758)and 0.16％ (16/9 758),respectively.In 10 of 16 yield cases,only the anaerobic culture was positive.The most of the bacterial detected by anaerobic culture only were Propionibacterium acnes.Their mean detection time from inoculation was 96.8±18.21 hours.Conclusion Addition of anaerobic culture would enhance the detection of bacterial contamination in PCs.However,since only slow-growing bacteria were detected,and because their clinical significance was debatable,blood service should select feasible and costeffective projects using only aerobic bottle for bacterial screening,like the majority of licensed blood centers in North America and Hong Kong,China.

The hospital the authom work with, the first one to undergo the second-cycle nation-wide hospital evaluation, was assessed by a third party and the hospital evaluation experts. The two cycles of hospital evaluation were entirely different in historical background, priorities and procedures. The evaluation standards for the second cycle, which were on a par with internafional ones, set the right track of development for medical institutions, emphasizing quality, security, service and performance and highlighting the delivery of quality patient care. The gains from the second-cycle hospital evaluation can be summarized as follows: more highly emphasized continuous improvement of service quality, enhanced awareness of people-oriented management, reinforced medical quality and medical security control, heightened hospital infection control, greater capability of responding to emergencies, and strengthened for-malation of hospital rules and regulations. In the end five suggestions are put forward with regard to the second-cycle hospital evaluation.

Objective:To investigate the anatomy of mandibular incisors using microcomputed tomography(Micro-CT).Methods:62 extracted mandibular incisors were selected from dental clinic and observed by Micro-CT.The anatomy of the teeth was analyzed. Results:83.9% of mandibular incisors had a single canal,72.6% had no accessory canal.The location of the apical foramen varied considerably.The mean distance from the root apex to the major lateral apical foramen was (0.613 ±0.298)mm.Of the canals the bucco-lingual diameter were greater than the mesio-distal diameters and the root bucco-lingual canal tapers were greater than the me-sio-distal.Conclusion:The morphology data of mandibular incisors were obtained using Micro-CT.

This experiment was made on 4-6 week-old nude mice(NM). The CNE-2 cells were inoculated subcutaneously into each side of the neckback for the original generation. Implanted fresh transplanted NPC tissue to NM's neck-back with cannula for next passage. We passed up to 8 generations and the transplantability was 100%. We observed dynamicrly the changes of NM's immune status after they have bearing the NPC as following: (1) The net weight was significantly reduced. (2) Splenic index(S. I.) and tumor weight(T. W.) increased. S. I. was highly related to T. W. (r=0.8395). (3) Splenic NK activity slightly increased in 5 days, began to decrease in 10 days and significantly decreased in 15 or more days. NK activity was negative related to T. W. and S. I. markedly (r=-0.7132, r=-0.8237). (4) Splenic NK cells had excellent responsiveness to human IFN in vitro in 5 days and still had some in 10 days, but it had not any after 15 days. (5) Natural proliferative ratio of tumor bearing NM's splenic cells was higher than that of control group, but the responsiveness to ConA was much lower. (6) Ai Ke Xing suppressed the growth of transplanted NPC by means of decreasing sera MDA enhancing host's splenic NK activity and increasing mononuclear infiltration of the transplanted NPC tissue. So we concluded that in NM whose T cells were deficient splenic NK cells were important immunocompetent cells for resisting the growth of transplanted NPC.
