Journal of Third Military Medical University 2003;0(18):-
Objective To explore the effect of c fos antisense gene transfection on the protection of cardiomyocytes following hypoxia and burn serum treatment. Methods Burn serum was collected from Wistar rats with 30% total body surface area(TBSA) of Ⅲ degree burns. The mixture gas containing 1% O 2 was used as hypoxia model. The c fos antisense gene recombinant was constructed by genetic recombination technique. Cardiomyocytes from neonatal Wistar rats were cultured in vitro with hypoxia and burn serum treatment. c fos antisense gene recombinant was transfected into the cultured cardiomyocytes. Expression of c fos mRNA was determined by RT PCR. Expressions of c fos protein, troponin T and ? Tubulin in cardiomyocytes were determined by Western blotting in the transfected and non transfected groups. Results RT PCR results showed that the expression of c fos mRNA increased significantly in the non transfected group. But after transfection of c fos antisense gene recombinant, the expression of c fos mRNA decreased significantly as compared with the non transfected cardiomyocytes. Western blotting results showed that the expression of c fos protein in the transfected group decreased remarkably as compared with the non transfected group, but the expressions of ? Tubulin and troponin T increased significantly in the transfected group. Conclusion Burn serum and hypoxia can cause the injury of cardiomyocytes. c fos antisense gene recombinant transfection has the protective effect on cardiomyocytes exposed to burn serum and hypoxia.

Chinese Journal of Organ Transplantation 2015;36(3):176-179
Objective To investigate the attitudes of medical students regarding to organ donation compensation.Method A self administered questionnaire was distributed to 600 medical students selected randomly from two medical universities in China between January 2013 and January 2014.The questionnaire included demographics and core questions related to medical student's attitudes regarding organ donation compensation.Result A total of 600 questionnaires were distributed and 592 valid responses were received,including 150 doctoral students,143 master students and 299 undergraduate students.In all,69.8% of medical students believed that compensation for organ donor was essential.Nearly 60.5 % believed financial compensation would increase the rate of organ donation but would not tarnish the behavior of organ donors (64.7%).At the same time,over 70% of medical students believed that financial compensation would increase the number of living organ donation.With regarding to the ways of compensation,most of the students (80.4%) were in favor of priority on waiting list.Reducing or free of hospitalization costs (50.4%) and increasing the reimbursement ratio of medical insurance (41.8%) were also the acceptable compensation ways to medical students.Conclusion Most of medical students believe that it is essential to give compensation to organ donors.Enjoying the priority on waiting list,reducing or free of hospitalization costs and increasing the reimbursement ratio of medical insurance are the reasonable incentive methods.

5.Effects of flavonoids on lipoxygenase activities and their biological functions
Chinese Journal of Pharmacology and Toxicology 2009;23(6):490-496
Lipoxygenase(LOX) is related to emergence and development of many diseases, such as acute and chronic inflammation, atherosclerosis, hypertension and tumor. Therefore, the inhibition of LOX may play an important role in the prevention and treatment of these diseases. Many kinds of flavonoids, such as chalcones, flavonols, flavones and flavanols, have inhibitory effect on 5-LOX, 12-LOX and 15-LOX probably through inhibiting expression of LOX, bonding to the enzyme or reacting with free radicals generated at the active site of the enzyme. Their inhibitory activities are related to their structures. The inhibitory effects of flavonoids on LOX maybe one of mechanisms of flavonoids' some biological functions, such as anti-inflammatory, anti-tumor and reducing the risk of cardiovascular disease and cerebrovascular disease.

Journal of International Oncology 2009;36(7):542-544
Objective Discussing the rationality of psychological intervening therapy in the treatment of early breast neoplasm. Methods By summarizing and reviewing 84 patients suffering from the early breast cancer between January of 2003 and December of 2005, we procured some information of their clinical manifes-tations, clinical therapy and statistic results of psychological assessment. Results By intervening the psycho-logical therapy, the patients' self-efficiency and living quality can be bettered. Conclusion Patients with early breast neoplasm need to have a comprehensive treatment with general or local therapy and individual psychologi-cal intervention. Nevertheless, it is rather practical to enhance the general level of prevention and therapy of breast neoplasm through the research of psychological problems after the operation.
7.Study of cell growth inhibition and apoptosis induced by oxaliplatin in human poor differentiation nasopharyngeal carcinoma cell line-CNE2
China Oncology 1998;0(01):-
Background and purpose:Backgrounds and Objective: Oxaliplatin is a third-generation platinum compound,there are some distinct differeuces in mechanism between cisplatin and oxaliplatin,and oxaliplatin is less toxic Poorly differentiated cartinoma is the most common histological type,for nasopharyngeal carcinoma,although radiotherapy is the basic therapeutic approach to nasopharyngeal carcinoma,chemotherapy is also important for recurrent and metastatic nasopharyngeal carcinoma,so in this work we analyzed the effects of oxaliplatin on nasopharyngeal carcinoma cell lines in vitro.Methods:CNE2 was incubated with oxaliplatin at various concentrations and times,cell growth inhibition was assessed by MTT-microculture tetrazolium assay,cell-cycle kinetics and apoptosis were analyzed by flow cytometry and microscopy transmission electron.Results:Growth of CNE2 cells was significantly inhibited in a dose-dependent and time-dependment fashion.The inhibition of cell growth inhibition was(95.6?0.7)% after incubation with 100 ug/ml oxaliplatin for 48 hours,the cell was arrested at G_(2)/M and apoptosis was induced.When CNE2 cells were treated with oxaliplatin at the concentration of 0、0.03、4.0、100 ?g/ml,the rates of CNE2 cell apoptosis were(0.19?0.17)% 、(0.37?0.09)%、(5.50?1.08)%、(9.43?0.09)%,respectively.24 hours after 20 ?g/ml the CNE2 cells were characterized by chromatin condensation,chromatin crescent formation,nucleus fragmentation and apoptosis body by transmission electron microscopy.Conclusions:Oxaliplatin suppresses the growth of CNE2 cells in vitro by causing cell-cycle arrest and cell apoptosis.

10.Effects of SAHA on hippocampal TLR4/MYD88 signaling and neuronal apoptosis after seizure in developing rats
Chinese Journal of Pathophysiology 2016;32(7):1208-1213
[ ABSTRACT] AIM:To investigate the effect of vorinostat ( suberoylanilide hydroxamic acid, SAHA) , a histone deacetylase inhibitor, on seizure-induced brain damage in developing rats and its mechanism.METHODS:Male Sprague-Dawley rats (n=32) were randomly divided into control group, pentylenetetrazole (PTZ) group, PTZ+10 mg/kg SAHA group and PTZ+50 mg/kg SAHA group.Intraperitoneal injection of PTZ was used to induce rat seizure.SAHA was injec-ted intraperitoneally 2 h before PTZ injection.The rats in different seizure stages were counted and mean seizure score was analyzed at 30~60 min after PTZ injection.Hippocampal tissues were sampled at 24 h after seizures.The expression of TLR4, MYD88, NF-κB P65 and IL-1βat mRNA and protein levels was detected by RT-qPCR and Western blot, respec-tively.The pathological changes of the brain tissues were observed by HE staining.The apoptotic neurons were observed by TUNEL staining.RESULTS:The mRNA and protein levels of TLR4, MYD88, NF-κB P65 and IL-1β, the apoptosis of neurons, the inflammation reaction and mean seizure score significantly increased after PTZ treatment (P<0.05), and these effects were attenuated by treatment with SAHA.Compared with PTZ+10 mg/kg SAHA group, PTZ+50 mg/kg SA-HA group showed more significant protective effect against seizure-induced brain damage.CONCLUSION: Histone deacetylase inhibitor SAHA suppresses seizure-induced TLR4/MYD88 signaling and reduces apoptosis of neurons, sugges-ting a protective effect against brain damage associated with seizure in developing rats.
