Journal of Chinese Physician 2000;0(12):-
Objective To explore the molecular mechanism of c-jun antisense gene transfection in protecting cardiomyocytes from injury of hypoxia and burn serum treatment. Methods Burn sera were collected from wistar rat with 30% total body surface area(TBSA) Ⅲ degree burn injury, and the mixture gas containning 1% O 2 was used as hypoxia model. The c-jun antisense gene recombinant vector was constructed. Neonatal wistar rat cardiomyocytes cultured in vitro were treated with hypoxia and burn sera. c-jun antisense gene recombinant vector was transfected into the cultured cardiomyocytes. Expressions of c-jun, PKC? and JNK were detected with western blot in the transfected and non-transfected cardiomyocytes. Results Expression levels of c-jun, PKC? and JNK significantly increased in the non-transfected cardiomyocytes when treated by hypoxia and burn sera, up to maximum 24 hour after the treatment. Expression levels of c-jun, PKC? and JNK in the transfected cardiomyocytes decreased significantly compared with non-transfected cells. Conclusions The transfection of the c-jun antisense gene recombinant vector protected cardiomyocytes from injury of hypoxia and burn sera treatment via down-regulating PKC? and JNK expressions.
2.Computed tomography angiography and magnetic resonance angiography evaluate coronary artery in children with Kawasaki disease
Chinese Journal of Applied Clinical Pediatrics 2014;29(13):966-967
Kawasaki disease can affect the coronary arteries,including coronary artery dilation,aneurysm,stenosis and thrombus.Conventional coronary angiography is the gold standard for coronary artery evaluation,but there are risks associated with its invasive nature and with the exposure to contrast agents and radiation.With the rapid development,computed tomography angiography and magnetic resonance angiography become the noninvasive imaging modalities to evaluate the coronary artery.
3.Discussion on magnesium ions in children with asthma exacerbation
China Medical Equipment 2014;(5):107-108
Objective:To determine blood magnesium and urinary magnesium in children with asthma exacerbation and discuss the relationship between the magnesium level and children with asthma attack. Methods:The observation group include 90 children who were 0~6 years old with asthma exacerbation that admission to our hospital since May 2008 to May 2012. The control group was 100 children with the same age to the observation group to accept the health examination. Every child in two groups were taking venous blood of 2ml and 24h urine samples. Record the amount of urine at the same time. Using automatic biochemical analyzer to detect the serum magnesium concentration and urinary magnesium concentration. Results: The urinary magnesium concentration of observation group was obviously lower than control group (t=8.52, P<0.001);the serum magnesium concentration of two groups had no significant difference (t=2.21, P>0.05). Conclusion:Children with asthma in acute attack stage with magnesium deficiency. Urinary magnesium concentration determination is simple, and it is a effective method that can be used to judge whether there is magnesium deficiency. Serum magnesium concentration cannot be used as a reliable indicator of magnesium ion balance.

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.

9.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.The attitudes of medical students regarding to organ donation compensation
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.
