Objective To understand the mainstream view of ethnic minorities and Han nationality in Yunnan province on Body donation, understand the present status and possible issues about body donation in Yunnan province, so as to provide reference for Yunnan province on body donation. Methods We conducted questionnaire survey by random sampling. Results Yi,Dai,Han on the body donation knowledge and Donation rate was low,and the Yi, Dai was lower than Han.promoting development of medicineandthat is the continuation of lifebecame the main factors affecting the willing to donate body,there was significant difference between the three ethnic groups ( <0.05) .After death should be laid to rest,family and public pressure,fear of being free to use,religious beliefbecome the main factors affecting the unwilling to donate body, three nations also had significant difference ( <0.05) .Conclusions Most people think that the whole society should pay close attention to body donation, that body donation is a very meaningful thing. Joint effort should be made by both the government and civil society for body donation programs in Yunnan Province.

Objective:To investigate the mainstream view and statusof people on body donation in Yunnan province, and provide references. Methods:Random sampling questionnaire survey was used, the obtained data was statistically analyzed. Results:Only 48. 0% of the people understand the body donation, 20. 6% of people know body donation ways and procedures, 27. 8% of people have heard of body receiving station, 11. 4% of people know the body receiving station in yunnan province, 17. 2% of the people to understand body donation of relevant laws and regulations. 47. 4% of people that are willing to donate his body. Conclusion:Make perfect laws and reg-ulations, respect for the body, giving donors and their families allowance, body donation monument, to carry out education and publicity of the body donation form to the whole society support and participate in the good atmos-phere of body donation has great benefits.

Objective:To study the relationship between neutrophil to lymphocyte ratio (N/L) and traditional cardio‐vascular risk factors among community 35~64‐year‐old residents .Methods :A total of 1884 residents (548 males and 1336 females) from urban Shenyang city received baseline condition questionnaire on cardiovascular diseases and re‐lated diseases from Apr 2011 to Feb 2012. According to presence of cardiovascular risk factors or not ,subjects were divided into healthy control group (n=675) and risk factor group (n=1209);according to number of risk factors , risk factor group was further divided into one risk factor group (n=491) ,two risk factors group (n=263) and ≥3 risk factors group (n=455) .Morning blood sample and urine sample were retained to measure blood and urine rou‐tine ,blood glucose and blood lipid profile etc in all subjects .N/L was compared and analyzed among all groups .Re‐sults:Among patients with only one of following risk factors [hypertension ,diabetes mellitus (DM) ,dyslipidemia and obesity] ,N/L levels of patients with hypertension or DM were significantly higher than that of healthy control group [1.55(1.15 ,1.95) ,1.60(1.21 ,2.07) vs .1.45(1.09 ,1.91)] , P<0.05 both ,and there were no significant difference between any other one risk factor group and healthy control group , P>0.05 all .Among risk factor sub‐groups ,N/L level of ≥3 risk factors group was significantly higher than that of two risk factors group [1.57(1.16 , 2.04) vs .1.41(1.07 ,1.89) ,P<0.05] ,and there was no significant difference between any other two groups (P>0.05) .Conclusion:N/L significantly related to hypertension or DM ,and N/L level of ≥3 risk factors group was sig‐nificantly higher than that of two risk factors group ,N/L is helpful to assess risk of cardiovascular diseases .

Objective To explore the optimal time for first ambulation out of bed after cesarean delivery,so as to provide a scientific basis for postoperative exercise guidance after cesarean section. Methods From January to December 2016,a total of 531 cases of cesarean section were selected and randomly divided into three groups. In the first group,the first time of out of bed ambulation was 6 to 8 hours (Group A);the second group was 9 to 11 hours (Group B);and the third group was over 12 hours (Group C). The maternal vaginal blood loss within 24 hours after operation,the first time of postoperative exhaust,wound healing,urinary retention,lower limbs deep vein thrombosis and maternal comfort and pain scores were assessed in the 3 groups. Results The differences in the first exhaust time,the comfort degree of first time ambulation,the pain scores of the first ambulation and 24 hours after operation among the 3 groups were statistically significant (F=4.541, 10.731,12.060,3.214;P< 0.05),and the comfort degree of Group A was better than those of the other two groups. There was no statistical difference in wound healing,urinary retention,lower limbs deep vein thrombosis and 24 hours postoperative comfort score among the 3 groups (P>0.05). Conclusions The most reasonable time for the first off-bed ambulation after cesarean section is 6 to 8 hours.

Objective To explore the effects of immediate skin contact in 90 minutes after birth on the start-up time of breast-feeding, so as to provide reference for clinical practice in promoting breast-feeding. Methods A total of 160 neonates delivered in the Department of Obstetrics and Gynecology of the First Hospital of Peking University from October 2016 to August 2017 were randomly divided into control group and observation group with 80 neonates in each group. The control group was given neonatal daily care after delivery. The observation group received early maternal infant skin contact at least 90 min after delivery. When feeding signals were present, mothers were encouraged to start breastfeeding. In the control group, 14 cases were lost in the late stage, and 5 cases in the observation group. The start-up time of breast-feeding, exclusive breast-feeding and duration of first breast-feeding were compared between the two groups. Results There was no significant difference between the two groups in the time of foraging, the time of connection, the time of sucking, the time of finishing sucking, the duration of first breast feeding, the rate of breast feeding completed within 90 minutes, and the rate of 3-month exclusive breast feeding (P＞ 0.05). The rate of starting breast-feeding within 30 minutes, breast-feeding before discharge and exclusive breast-feeding before discharge in the observation group were higher than those in the control group, and the differences were statistically significant (P＜0.05). Conclusions Early maternal infant skin contact within 90 min after delivery can improve the rate of breast-feeding, promote early onset of breast-feeding and the success of breast-feeding. It is worthy of adoption and application.

Objective To investigate correlation between QT interval(QT),corrected QT interval(QTc) and metabolic syndrome(MS). Methods Residents who participated in our survey concerning atherosclerosis and related diseases conducted in Shenyang were included. They accomplished questionnaire,physical examination, laboratory tests and electrocardiography test. We divided them into MS group and non-metabolic syndrome (NMS)group according to International Diabetes Federation(IDF)diagnostic criteria for MS. QT interval was measured from the standard 12-lead electrocardiogram. QTc was calculated by using Bazett and Fridericia equations. We analyze correlation of QT ,QTc and MS. Results A total of 739 residents who were 35~64 years old were included. Individuals with MS had longer QTcB and QTcF than NMS group[(415.8 ± 31.9)ms vs.(410.1 ± 32.1)ms, (407.2± 29.1)ms vs.(402.6 ± 28.8)ms,P<0.05]. The more the number of abnormal MS parameters they had, the longer the QT,QTcB and QTcF they had. Regression analysis showed that QT was associated with serum potassium,smoking,blood glucose,and LDL,and QTcB and QTcF were associated with hypertension,waist circumference and blood potassium. Conclusions MS is associated with corrected QTc. Careful ECG monitoring among persons with MS for early detection of a long corrected QT interval may prevent severe and often fatal arrhythmias or sudden death.
