Postoperative ankle function after systematic exercise with a self-designed foot-ankle exerciser in patients with tibial pilon fracture / 中华创伤骨科杂志

Objective:To analyze the effect of systematic exercise with a self-designed foot-ankle exerciser on postoperative ankle function in patients with tibial pilon fracture.Methods:A retrospective study was conducted of the 84 patients with tibial pilon fracture who had been treated by open reduction and internal fixation at Nanhua Hospital Affiliated to Nanhua University from May 2018 to January 2020. According to the difference in rehabilitation, they were divided into a control group ( n=42) which were subjected to staged functional rehabilitation after operation and an observation group ( n=42) which was subjected to systematic exercise with a self-designed foot-ankle exerciser. In the control group there was 26 males and 16 females with an age of (36.6±4.8) years (from 20 to 55 years); in the observational group there were 27 males and 15 females with an age of (36.4±4.5) years (from 21 to 57 years). The 2 groups were compared in terms of postoperative recovery, ankle functional recovery, postoperative quality of life, and rate of complications. Results:The 2 groups were comparable due to the insignificant differences in their preoperative general data ( P>0.05). The time for first ambulation [(3.7±0.3) weeks], time for fracture union [(9.1±0.8) weeks], and time for full-weight bearing [(6.5±0.9) weeks] in the observational group were all significantly shorter than those in the control group [(4.1±0.5) weeks, (10.9±1.2) weeks and (7.2±1.1) weeks] ( P<0.05). The good to excellent rate of ankle functional recovery was 92.9% (39/42) for the observational group, significantly higher than that for the control group (73.8%, 31/42) ( P<0.05). The scores for postoperative quality of life in the observational group were significantly higher than those in the control group in dimensions of material, psychology, society and body ( P<0.05). The rate of total postoperative complications in the observational group was 2.4% (1/42), significantly lower than that in the control group (10.9%, 8/42) ( P<0.05). Conclusions:For patients with tibial pilon fracture undergoing the same surgical procedures, systematic exercise with our self-designed foot-ankle exerciser can promote functional recovery of the ankle joint, improve postoperative quality of life, and reduce incidence of postoperative complications.

Association between dietary selenium intake and hypertension in Zhejiang residents / 预防医学

Objective@#To investigate the association between dietary selenium intake and hypertension among Zhejiang residents .@*Methods@#By multistage stratified random sampling method,four urban sites and two rural sites out of Zhejiang Province,four communities or villages out of each site,then 20 households out of each community or village were selected,and all the family members of the selected households were recruited as participants. The questionnaire of Chinese Health and Nutrition Survey was used to collect information about socio-demographic characteristics and dietary selenium intake. The blood pressure,blood lipid and other data were collected via physical examination. A multivariate logistic regression model was used to analyze the relationship between dietary selenium intake and hypertension .@*Results@#A total of 1 222 participants with complete dietary selenium intake data were included for analysis. The number（%）of participants with selenium intake higher than the level of estimated average requirement（EAR）,between the levels of EAR and recommanded nutrient intake （RNI）,between the levels of RNI and upper intake（UI）and higher than the level of UI were 729 （59.66%）,151（12.36%）,341（27.91%）and 1（0.01%）,respectively. There were 283 （30.53%）patients with hypertension out of 927 participants examined. The mean amount of selenium intake in patients with hypertention was（43.06±20.96）μg/d,which was significantly lower than（51.56±30.06） μg/d in non-hypertention participants（P<0.05）. After adjusting for age,body mass index,total cholesterol,triglyceride and diabetes mellitus in the multivariate logistic regression model,dietary selenium intake significantly reduced the risk of hypertension（OR=0.985,95%CI：0.978-0.993） .@*Conclusion@#About 60% of residents in Zhejiang Province had lower dietary selenium intake than estimated average requirement. Higher selenium intake was associated with lower risk of hypertension.

Influence of aspirin on nerve injury of experimental cerebral ischemia in rabbits / 中国病理生理杂志

Platelet play an important role in cerebral ischemial nerve injury. Aspirin (ASA) had been used to treat and prevent stroke in clinic. 30 rabbits were randomly divided into A, B and C groups. In group A ASA was given orally at a daily dosage of 15 mg/kg per rabbit for 5 days before cerebral ischemia; group B cerebral ischemia without giving ASA, and group C was normal rabbits as controls. The cerebral ischemial model was produced by occluding bilateral carotid arteries and bleeding from femoral artery. The results indicated that there was an obvious decrease of PAgT and TXA_2 and had no significance changes in free radicals increasing and Ca~(2+) rising from cerebral tissue in group A. The cerebral edema of group A was less severe than group B. It seemed that ASA had a protective effect on the nerve injury of cerebral ischemia. The derangement of ASA, platelet, free radicals and calcium ions interrelation and their significance on the nerve injury should be further studied.

STUDY ON THE RELATIONSHIP BETWEEN DIETARY CARBOHYDRATE AND GLYCEMIC LOAD AND DYSLIPIDEMIA RISK IN ADULTS / 营养学报

Objectives To analyze the relationship between dietary carbohydrate and glycemic load(GL) and the plasma lipid level and dyslipidemia risk. Method The sample of adults above 18y of age from "National Survey on Nutrition and Health Status of the Chinese People 2002" was used,excluding pregnant women,mothers and people who controled their diets. Data of GI from China Food Composition 2002 and International Glycemic Index Table 2002 were used. The dietary GL as the indicator of dietary carbohydrate was calculated by multiplying the carbohydrate content of each food by its glycemic index,then multiplied by frequency of consumption and summed up from all food. Correlation analysis,multiple regression and Logistic regression were used to analyze the relationship between dietary GL and plasma lipid level and dyslipidemia risk. Results Dietary GL remained inversely associated with plasma total cholesterol(TC) and low density lipoprotein cholesterol(LDL-C) . With the increase of dietary GL,the risk of hypercholesterolemia and high blood LDL-C decreased. In the meantime dietary GL remained negatively associated with plasma high density lipoprotein cholesterol(HDL-C) . With the increase of dietary GL,the risk of low blood HDL-C increased. Dietary GL remained inversely associated with plasma triglyceride(TG) ,but showed no significant influence on risk of hypertriglyceridemia. Conclusion The traditional Chinese dietary pattern which is characterized by cereals as staple food is helpful to decrease dyslipidemia risk.

SURYEY ON THE DISTRIBUTION OF DIETARY GLYCEMIC LOAD IN CHINESE ADULTS / 营养学报

Objectives To investigate the consumption of carbohydrate and distribution of dietary glycemic load (GL) in Chinese adults. Method Data from China National Nutrition and Health Survey in 2002 were used for this analysis. Dietary glycemic load was calculated as a function of glycemic index, carbohydrate content and frequency of intake of individual foods. Results Dietary glycemic load was contributed by 92% from cereals. People with low dietary GL /4184 kJ tended to consume more fat, less cereals, and less carbohydrates. The prevalence of overweight and obesity was higher in those with low GL/4184 kJ, especially in urban residents. Conclusion People with low GL/4184 kJ tend to consume more fat, less cereals, less carbohydrates. The situation in urban residents is more serious. Based on factors including cereals intake, energy contribution from fat and carbohydrates, prevalence of malnutrition, overweight and obesity. A proposed range for dietary GL /4184 kJ in Chinese adults can be 80~120.
