Associations between Takeaway Food Nutrients and Nutritional Literacy of Takeaway Platform Practitioners in Chengdu / 中国医学科学院学报

Objective To investigate the nutritional literacy levels of the takeaway platform practitioners in Chengdu,the takeaway food nutrients,and the correlation between them.Methods We employed a multi-stage random sampling method to investigate the nutritional literacy levels of 100 takeaway platform restaurants in the main urban area of Chengdu and examined the nutritional components of hot set meals in each restaurant.A questionnaire survey was conducted on the nutritional literacy levels of chefs and food matching staff.The correlations of nutrient energy supply rationality with nutritional literacy level and set meal price were then analyzed.Results The total pass rate of nutrition knowledge of chefs/food matching staff was 61.0%.Only 2.0% of the set meals had reasonable total energy supply.The set meals with reasonable energy supply of available carbohydrate,protein,and fat accounted for 3.0%,62.0%,and 21.0%,and those with over energy supply accounted for 97.0%,26.0%,and 73.0%,respectively.The rest set meals provided insufficient energy.There was a positive correlation between the nutritional literacy level and the rationality of protein energy supply(r=0.414,P=0.003).Conclusions The nutritional literacy levels of chefs/food matching staff of takeaway food restaurants in Chengdu are moderate.The hot set meals on the takeaway platform have the problem of excess energy supply.The nutrition knowledge of chefs/food matching staff cannot effectively satisfy rational nutrition matching.The nutritional literacy levels of chefs/food matching staff showed no significant correlation with the rationality of nutrient energy supply.

Nutritional Knowledge and Skills of Fast-food Takeout Practitioners in Chengdu City / 中国医学科学院学报

Objective To investigate the current status of nutritional knowledge and skills of fast-food takeout practitioners in Chengdu City,so as to provide evidence for nutritional literacy education among takeout practitioners.Methods A questionnaire survey was conducted among 832 employees of fast-food takeout restaurants in Chengdu from April to September in 2019 through a multi-stage random sampling strategy.Results The awareness rate of nutritional knowledge of fast-food takeout practitioners in Chengdu was 77.28%,and the correct rates of answers to daily oil intake for adults,daily drinking water for adults and daily salt intake for adults in the Dietary Guidelines for Chinese Residents were respectively 17.43%,22.60% and 25.36%.In addition,the proportion of practitioners with the ability to estimate the recommended intake of food for a meal,the ability to estimate condiments intake and the ability to interpret nutrition labels were 8.77%,8.77% and 15.02%,respectively.The awareness rate of nutritional knowledge was the lowest(71.47%)in the practitioners aged≤25 and the highest(84.53%)in those aged 26-39,and the difference was statistically significant(χ

Young Children's Family Sex Education in Rural Areas of Sichuan Province and Its Influencing Factors / 中国医学科学院学报

To understand the family sex education for young children in rural areas of Sichuan province and analyze the influencing factors. A multi-stage random sampling method was used to select 2246 parents of kindergarten children from rural areas in Sichuan province for a questionnaire-based survey.The Chi-square test and Logistic regression model were used for data analysis. It was found 1132(52.33%)parents had implemented family sex education for young children and 1031(47.67%)had not.Young children having asked sex-related questions(=1.536,95%=1.257-1.878),parents thinking that early childhood sex education is necessary(=3.691,95%=2.029-6.717),and parents having the intention to know early childhood sex education(=1.700,95%=1.274-2.269),and kindergarten having implemented early childhood sex education(=3.316,95%=2.515-4.372)were promoting factors for parents to conduct early childhood sex education,whereas a total annual household income at the middle level(=0.664,95%=0.456-0.968)was a hindering factor for parents to conduct early childhood sex education. Parents of young children in rural areas of Sichuan province have poor awareness of sex education,and the proportion of parents who have never conducted sex education for children is high.The total annual income of the family,whether the children have asked about sex-related questions,parents' attitude towards early childhood sex education,and whether the kindergarten has conducted the early childhood sex education are important factors that influence the level of children's family sex education.

Efficacy of thunder-fire moxibustion combined with external applicaion of powder for mild and moderate knee osteoarthritis / 中国针灸

OBJECTIVE@#To compare the therapeutic effect between thunder-fire moxibustion combined with external applicaion of powder and thunder-fire moxibustion alone for mild and moderate knee osteoarthritis.@*METHODS@#A total of 70 patients with mild and moderate knee osteoarthritis were randomly divided into an observation group and a control group, 35 cases in each group. In the observation group, thunder-fire moxibustion combined with external applicaion of powder were applied, Thunder-fire moxibustion was applied at Xuehai (SP 10), Liangqiu (ST 34), Neixiyan (EX-LE 4), Yanglingquan (GB 34) and point, external applicaion of powder was given to the affected knee after the treatment of thunder-fire moxibustion. Simple thunder-fire moxibustion was given in the control group. All patients in the two groups were treated once a day, 7 days as one course and the consecutive 4 courses were required, with an interval of 1 day between courses. Before and after treatment, the visual analogue scale (VAS) score and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were used to assessed knee pain, stiffness and physical function in the two groups. In addition, the efficacy was evaluated.@*RESULTS@#Compared before treatment, the VAS scores, total scores of WOMAC, pain scores, stiffness scores and physical function scores were reduced after treatment in the two groups (<0.01), and the scores in the observation group were significantly lower than those in the control group (<0.01, <0.05). The total effective rate was 97.0% (32/33) in the observation group, which was superior to 91.2% (31/34) in the control group (<0.05).@*CONCLUSION@#Thunder-fire moxibustion combined with external applicaion of powder are superior to simple thunder-fire moxibustion in improving the symptoms and delaying the development of the disease for mild and moderate knee osteoarthritis.

A Study on the Effects of Cold Knife Excision by Hysteroscopy for the Local Microcirculation and Inflammatory Reaction of Patients with Hysteromyoma / 昆明医科大学学报

Objective To study and observe the effects of cold knife excision by hysteroscopy for the local microcirculation and inflammatory reaction of patients with hysteromyoma.Methods 86 patients with hysteromyoma admitted in our hospital from March 2016 to July 2017 were selected as the research objects,and the patients were divided into control group with 43 cases and observation group with 43 cases according to the method of random number table.The control group were treated with monopolar electric knife excision by hysteroscopy,while the observation group treated with cold knife excision by hysteroscopy.Then the local microcirculation and inflammatory reaction indexes of two groups at different time before and after the operation were detected.Results The local microcirculation and inflammatory reaction indexes of two groups before the operation were compare,no significant differences found (P＞0.05);the local microcirculation indexes of observation group after the operation were significantly better than those of the control group,the inflammatory reaction indexes were significantly lower than those of the control group,both with statistical significance (P＜0.05) .Conclusion The cold knife excision by hysteroscopy has better clinical effects in the control of local microcirculation and inflammatory reaction in patients with hysteromyoma,so it has higher application value in the patients with hysteromyoma.
