AIM To study the protection of 6,7 dimethexycoumarin on hypoxic animals. METHODS The effect of 6,7 dimethexycoumarin on survival time and survival rate of mice subjected to hypobaric, normobaric and chemical hypoxia were observed and the oxygen consumption of isolated tissues were measured. RESULTS 6,7 dimethexycoumarin obviously prolonged the survival time and promoted the survival rate of hypoxic mice, increased the mouth opening time of isolated mice and reduced the oxygen consumption of isolated cardiac muscle of mice. This contributes to exploring the mechanism of antiradiation and poison reducing of 6,7 dimethexycoumarin. CONCLUSION 6,7 dimethexycoumarin shows remarkable effect on tolerance to hypoxia in mice.

Facing the current situation of scientific literacy in vocational medical school, med-ical science literacy education has been penetrated into the teaching process of human functionology by measures of combining with research materials and clinical cases, increasing the proportion of ex-perimental teaching, stressing comprehensive practical projects and carrying out the ‘competitive learning’ to improve competency and occupation competitiveness of vocational medical students.

Objective The objective of this study is to investigate whether there is a correlation between a high TyG index(serum triglyceride glucose index)and higher mortality rates among patients undergoing peritoneal dialysis(PD).Methods This study utilized a single-center retrospective cohort as the basis for its methods..From January 1,2007 to December 31,2015,a total of 519 PD patients kept under observation until December 31,2018.There searchers employed the Kaplan-Meier method and Cox proportional hazards modelsto examine the cor-relation between TyG index levels and mortality.Results Over a period of 40.5 months,104(20.0%)individuals with Parkinson's disease passed away,with 55(52.9%)of these deaths attributed to cardiovascular disease(CVD).The serum median TyG index at baseline was 8.44(6.48,11.94).Through Cox regression analysis subject to the adjustments of such parameters as gender,age,body mass index(BMI),presence of cardiovascular disease,hypertension,diabetes mellitus,hemoglobin,serum albumin,serum Ferritin,total cholesterol,renal residual function(RRF),An increased risk of all-cause mortality(HR = 2.22,95%CI:1.43~3.44,P<0.001)and CVD mortality(HR = 2.50,95%CI:1.34~4.65,P = 0.004)was observed with a higher baseline TyG index(8.44).A comparable impact was observed in the correlation between the average TyG index over time(TA-TyG index)and both all-cause mortality and CVD mortality.(HR = 1.90,95%CI:1.25~2.90,P = 0.003;HR = 2.05,95%CI:1.14~3.70,P = 0.017,respectively).Conclusion PD patients with a higher serum TyG index have a greater risk of all-cause mortality and mortality related to cardiovascular disease.
