Objective To comparison anterior cervical decompression and plating techniques for CSM between under microscope and traditional method retrospectively, investigate clinical result of surgery under microscope. Methods Sixty-seven patients with CSM underwent surgery of anterior cervical decompression and plating techniques were evaluated retrospectively from January 2008 to June 2010. Thirty-three patients underwent operation under microscope; thirty-four patients underwent traditional operation. The operating time, bleeding volume during operating and poster operating, walking time post-operation and complication were observed. Clinical outcomes were assessed by Japanese Orthopaedic Association (JOA), Image of before and after operation. Results Microsurgery operation time averaged of 100 minutes. Bleeding volume during the operation averaged of 60 ml, and after operation averaged of 40 ml. The JOA scores were improved from 8.43 pre-operatively to 14.70. Six months post operation, the average rage of JOA improvement were 83.2%. Traditional operation time averaged of 115 minutes. Bleeding volume during operation averaged of 100 ml, and after operation averaged of 50 ml. The JOA scores were improved from 7.45 pre-operatively to 11.84. Six months post operation, the average rage of JOA improvement were 82.1%. There were difference between two groups(P > 0.05) in the JOA scores. No statistical difference (P < 0.05) in bleeding volume and operating time. Conclusion The operation under microscope is restored significantly than the traditional method in bleeding volume, the surgical field, safety of operation, time of recovery and so on.

Objective To explore the effect and adverse reaction of priming regimen CAG in treatment of acute myeloid leukemia in elderly.Methods 32 elderly patients with acute myelogenous leukemia were treated with CAG regimen and 25 cases with standard chemotherapy regimen( DA regimen). The effect and adverse reaction were compared between the two groups. Results There was no significant difference of the complete remission rate and effective rate between the two groups. The recovery time of bone marrow and death rate of CAG the regimen group were superior to those of the DA group. Conclusion CAG regimen was effctive and safe for elderly patients with acute myeloid leukemia.

Objective To investigate the curative effects of the traditional surgical method of posterior pedicle Schanz screw fixa-tion with partially stripping injured paravertebral muscle in treating thoracolumbar fracture .Methods 52 cases with thoracolumbar fracture underwent posterior pedicle Schanz screw fixation to partially strip injured paravertebral muscle from January ,2010 to Jan-uary ,2012 .The patients were divided into partially stripping injured paravertebral muscle group (32 cases) and traditionally strip-ping injured paravertebral muscle group(20 cases) .The blood loss ,postoperative drainage ,kyphosis postoperative 3 d VAS scores , vertebral height correction rate ,Cobb angle correction ,Oswestry dysfunction indexes were copmared .Results Comparing with tra-ditionally stripping injured paravertebral muscle group ,the partially stripping injured paravertebral muscle group has better effect in transperative blood loss ,postoperative drainage and postoperative 3 d VAS scores ,the differences were statistically significant .But there was no statistical significance between the two groups in vertebral height correction rate ,kyphosis Cobb angle correction ,Os-westry dysfunction indexes .Conclusion Partially strip injured paravertebral muscle has less painful than traditional surgery does , being safe and effective with small invasion and easy to recover .

Monascus spp.,a kind of filamentous fungi,produce abundant of important metabolites which were widely used in the fields of food and medicine.Until now,there are few reports on the important functional genes of the Monascus spp.due to little genetic information.In this paper,the feasibility of gene deletion mediated via Agrobacterium tumefaciens on the basis of homologous recombination was analyzed by studying on the deletion of the RGS domain of putative G-protein signaling regulator gene mrfA in Monascus ruber.The length of homologous arms of deletion vector pC805S were 958 bp and 824 bp,respectively.There were 26 transformants in which homologous recombination occurred in 138 transformants and the recombination rate was 18.8%.The result showed it was feasible to identify the function of unknown gene in M.ruber with the targeted-deletion technology mediated via A.tumefaciens.

Objective To investigate the therapeutic effect of trans-TrkC gene neural stem cells (NSCs)on the recovery of neural function after spinal cord injury.Methods Sixty SD rats were ran- domly divided into six groups:normal control group(A),hemisection group(B),NSCs transplantation grnup(C),NSCs transplantation with the regional application of NT-3 group(D),trans-TrkC gene NSCs transplantation group(E)and trans-TrkC genc NSCs transplantation with the regional application of NT- 3 group(F),10 rats in each group.Nine days after the set up of animal models,cell transplantation into the injured spinal cord was performed.The BBB locomotor score was calculated,and MEP(motor evoked potential)and SEP(somatesensory evoked potential)were pedormed two months after cell transplanta- tion.Results Two months after cell transplantation,the BBB locomotor score was partly recovered, and the MEP and SEP(somatosensory evoked potential)results were also markedly improved in Group F, which indicated the restoration of the upward and downward nerve conduction function of the injured spinal cord.But it seemed that the restoration of the downward nerve conduction was better than that of the up- want,and the extent of the improvement of MEP and SEP results was larger than that of motion function recovery.The onset latency,peak to peak amplitude of MEP and SEP,and the BBB score of Group F re- stored the best compared with the other groups,and the differences were statistically significant(P

AIM: To explore the localization and expression of transfo rming grow th factor-? 1,2 (TGF-? 1,2 ) and alpha-smooth muscle actin (?- ASMA) in fetal a nd adult skins. METHODS: Skins of 15 cases of fetuses with different gestational ages and 5 cases of adults were taken, embedded with paraffin wax, and sectione d. Immunohistochemistry method and pathological method were used to detect the e xpression intensity and distribution of TGF-? 1,2 and ?-ASMA. RESULTS: Positive immunohistochemical signals of TGF-? 1,2 and ?-A SMA were found in fetal and adult skins. In skins derived from young fet us, the positive signals of these three proteins were very weak. Along with the incr ement in gestational age, the positive cellular rates of TGF-? 1,2 and ?- ASMA were elevated pro gressively. In elder fetal and adult skins, TGF-? 1,2 were mostly distributed i n epidermal cells, endothelial cells and some fibroblasts, while ?-ASMA was mainly located in myofibroblasts and sweat gland epithelial cells. CONCLUSION: The endo genous TGF-? 1,2 might be involved in the cutaneous development at embryoni c stage, in the cutaneous structure maintenance at adult stage, and in the wound healing af ter injury.
