TNF? mRNA in human bronchoalveolar lavage(BAL)cells was quantitated by a olymerase chain reaction(PCR)using a cRNA internal standard,cRNA molecules were in vitro transcribed from pAW108 plasmid in which the sequences of upstream primer and omolementary sequences of downstream primer of TNF? were inserted.The cRNA and mRNA extracted from BAL cells were mixed and reverse-transcribed into cDNA.The resultant cDNA mixture was 1:3 diluted and amplified by PCR using TNF? specific primers.~(32)p-labeled upstream primers were included in the PCR reaction,cDNA fragments amplified was run on a 3% agarose gel.The radioactivity of positive bands was determined in a scintillation ounter.After plotting variable template concentrations of the internal standard pAW108 cRNA and the number of BAL cells against the radioactivity of their PCR products,the levels of TNF? mRNA in BAL cells were quantitated by comparision to those of cRNA internal standard.

Objective To study the potential effect of gene-environment interaction between glutathione S-transferase M1 (GSTM1) and serum organochlorines residues on the risk of breast cancer in women, in China. Methods Seventy newly pathologically diagnosed female patients with breast cancer from September 2006 to October 2007 were selected as the cases from five large hospitals in Tangshan. The controls were identified at the same hospital as cases. 1∶1 matched case-control study. Between the cases and controls, the difference of age was not over two years and the residence was similar. The organochlorine residues levels in the serum were measured by gas chromatography (GC). Genotypes of GSTM1 polymorphisms were analyzed by multiplex allele-specific polymerase chain reaction (PCR). Interaction indexes (?) were calculated to determine the type of gene-environment interaction. Results After confounding factors adjusted, the result showed that interaction existed in genetic polymorphisms of GSTM1 and DDT, HCH residues, and interaction indexes (?) value were 1.237 and 1.379. Conclusion GSTM1 genetic polymorphisms and DDT, HCH may present an interaction in the development of breast cancer.

Objective To investigate the effects of propofol on apoptosis following focal cerebral ischemia-reperfusion in a rat model of reversible middle cerebral artery occlusion(MCAO) .Methods Twenty-four male SD rats weighing 300-500 g were randomly divided into 3 groups: group I sham operation; group Ⅱ MCAO + normal saline; group Ⅲ MCAO + propofol. MACO was produced by insertion of a 2-0 nylon filament with rounded end into internal carotid artery toward brain until resistance was encountered. The depth of insertion was about 2 mm. The filament was withdrawn after 2 h for reperfusion. In group I (sham operation) carotid artery was exposed but no filament was inserted. In group Ⅲ (propofol) intraperitoneal propofol 100 mg?kg-1 was administered 20 min before reperfusion; while in groupⅡ(normal saline) normal saline was given instead of propofol 20 min before reperfusion. At the end of 2 h reperfusion the animals were decapitated and the brain was removed. Apoptosis was identified by TUNEL technique. Cellular structure was examined under light microscope. Results Propofol significantly inhibited neuronal apoptosis following focal cerebral ischemia-reperfusion. Swelling and necrosis of the neurons were significantly attenuated in group III . Conclusion Propofol protects neurons against focal cerebral ischemia-reperfusion in rats.

Objective To study the effect mechanism of anticancer synergic (KangAiZengXiao,KAZX) decoction on gastric cancer in immunologic deficit rats with implanted tumor. Methods Forty rats were divided into normal control group(n=10), model group(n=15) and KAZX treating group(n=15). Model group and KAZX group were subcutaneously injected axillary the left upper limb with 0 5ml gastri cancer cells,MGC-803 cell(1?10 7/ml) after irradiated by 60 Co(dose:10Gy). Then the three groups were treated with KAZX decoction or distilled water every day, respectively. After three weeks, the rats were sacrificed,and blood WBC, the weight of spleen, activity of NK cell and transformation efficiency of lymphocyte were also detected.Results The rate of loaded tumor in KAZX group was significantly lower than in model group(20% vs 66 7%,P

AIM:There are some reports about the treatment of spinal cord injury with neural stem cells(NSCs) transplantation,but the ideas about the transplantation time and patterns and detection indexes are still different.In this study,the effects of cryopreserved NSC transplantation on the axonal regeneration after the spinal cord injury in rats were observed.METHODS:The experiment was carried out in the experimental animal center of China Medical University from June 2005 to June 2006.①Thirty-six adult Wistar rats,either male or female and 250-300 g,were provided by the experimental animal department of China Medical University.Neural stem cells were isolated from 10 neonate rats and cultured.All treatments for animals were accorded with the animal ethical criteria.②NSCs at logarithmic phase were cryopreserved at-70 ℃ for 2 weeks and labeled with 5-bromodeoxyuridine(Brdu) after rewarming.After the models of spinal cord injury were established,the NSCs were transplanted into the injured site immediately.Thirty-six rats were randomly divided into NSC transplantation group,DMEM solution group,and control group.③NSC survival and migration were detected by immunohistochemistry,and the reconstruction of spinal cord were detected by horseradish peroxidase(HRP) staining.RESULTS:Of the 36 spinal injured model rats,4 died of overdose of anesthesia,and 5 died of infection,but all were supplemented.Brdu-labeled positive NSCs were detected in the injured spinal cord after transplantation on the 7th day,and increased on the 14th day,then gradually decreased since the 28th day till disappeared.The number of HRP positive cells in transplantation group was significantly higher than DMEM solution.CONCLUSION:Cryopreserved NSCs can survive in the injured site after transplantation and promote the reconstruction of axoplasm pathway of injured spinal cord.

An overall improvement of teaching quality is the core task of the reform and the development of higher education. Based on the analysis of the main factors of affecting the teaching quality in universities and combined with the implementation of “views on improving the overall qual-ity of higher education”by the Education Ministry, countermeasures for improving the teaching quality of undergraduates have been proposed such as increasing higher education funds investment to im-prove the condition of running a school, paying attention to the construction of teaching management staff to improve the level of teaching management, establishing Teacher Development Research Center to consolidate the fundamental position of undergraduate teaching , utilizing the high-quality social resources to implement the collaborative education innovation, and improving the personnel training system to strengthen the teaching quality standard .

In recent years,the humanistic quality education in vast number of medical colleges and universities shows a low level of wandering state.This in not only related with the poor condition of current humanistic quality course,but also related with the diametrically opposed humanistic quality education and medical professional education and lack of organic integration.To improve the medical colleges' educational level is urgent to establish the concept of holographic education of great medicine,great education and great culture,improve the teaching quality of current humanistic quality education,actively explore the deep integration of humanistic quality education and medical professional education,improve the humanistic quality and nurturing ability of teachers staff in medical universities and colleges,and so on.
