ABSTRACT
Objective@#To analyze the relationship between family behaviors and overweight/obesity in primary and junior school students aged 6-14 years in Xuzhou, and to provide a reference for a targeted measure to prevent and control overweight and obesity.@*Methods@#Using multistage stratified cluster random sampling, a total of 6 220 students aged 6-14 years old from 10 primary schools and 10 junior schools were investigated by a self-designed questionnaire. Chi-square and multivariate Logistic regression models were used to explore the relationship between family behaviors and overweight/obesity in primary and junior school students.@*Results@#The rate of overweight/obesity in primary and junior boys was higher than that in primary and junior girls. The rate of overweight/obesity in urban students was higher than that of rural students(P<0.05). The Chi-square analysis showed that overweight of parents, irregular breakfast, eating fast food, eating sweets, drinking sweetened beverage, long screen time and short sleep duration were risk family behavior factors of overweight/obesity in primary and junior boy students(P<0.05). The risk family behavior factors of overweight/obesity in primary and junior girl students were overweight of parents, irregular breakfast, eating fast food and eating sweets(P<0.05). The risk family behavior factors of overweight/obesity, such as drinking sweetened beverage and short sleep duration, were also related to primary girls(P<0.05), and long screen time was related to junior girls(P<0.05). The multivariate Logistic regression showed that such family behavior factors as irregular breakfast(OR-boy=1.58, OR-girl=1.74), eating fast food(OR-boy=1.37, OR-girl=1.11), eating sweets(OR-boy=1.85, OR-girl=1.52), drinking sweetened beverage(OR-boy=1.64, OR-girl=1.33) and short sleep duration(OR-boy=1.56, OR-girl=1.69) were positively correlated with the prevalence of overweight/obesity in primary students. Long screen time was also correlated to overweight/obesity primary boy students(OR=1.18). Family behavior factors for child overweight and obesity induded overweight of parents(OR-boy=1.29, OR-girl=1.23) and eating sweets(OR-boy=1.44, OR-girl=1.51). Irregular breakfast(OR=1.51), eating fast food(OR=1.22), drinking sweetened beverage (OR=1.75) and long visual screen time (OR=1.15) were also positively correlated with the prevalence of overweight/obesity in junior boy students.@*Conclusion@#Family behavior factors were positively correlated with the prevalence of overweight/obesity in primary and junior students. The influence of family behavior factors were different between primary and junior students. Behavioral interventions based on family should be adopted to prevent and control the overweight/obesity of children.
ABSTRACT
Objective Enzyme triggered multi unit colon targeting mini tablet of indomethacin were prepared,in order to improve the target treatment of colon disease.Methods Different proportion of enteric layer and chitosan layer were screened to optimize the prescription.The colon targeting mini tablets were prepared by direct compression method.The drug release properties were investigated in different release medium.Rats were used to investigate the distribution of tissue in vivo.The Beagle dogs were used to study the pharmacokinetics and bioavailability.Results The optimum chitosan layer prescription:coating liquid concentration was 2％,plasticizer three citric acid ethyl ester (TEC) was 15％,an anti sticking agent amount of talc was 30％,coating weight was 5％;Enteric layer prescription:coating liquid solid content was 20％,plasticizer content of TEC was 5％,anti sticking agent talc powder dosage was 40％,coating weight was 3％.The chitosan multi unit colon targeted preparation seldom released in rat stomach and small intestine,released slowly in colon.The pharmacokinetics parameters in Beagle dogs were:Cmax =(3.25 + 0.672) mg·L-1,tmax =(2.00 + 0.014) h,AUC(0.∞) =(10.2 +0.871) mg·L-1 ·h,MRT (0-∞) =(2.82 + 0.180) h,CL =(2.46 + 0.202) L·h-1 ·kg-1.The release time of mini tablets for colon targeted was significantly prolonged and preserved stable blood concentration.Conclusion The enzyme triggered multi unit colon targeting mini tablet of indomethacin showed good target to colon and sustained release effect,providing an important reference for the development of preparation of indomethacin for the treatment of colon disease.
ABSTRACT
Objective To observe the clinical efficacy of reinforcing and reducing by acupuncturing at lower He-sea points along and against channel's direction in treating gastroesophageal reflux disease (GERD).Method Sixty-one GERD patients were randomized into a treatment group of 34 cases and a control group of 27 cases. The treatment group was intervened by reinforcing and reducing by acupuncturing at lower He-sea points along and against channel’s direction, while the control group was treated with oral administration of Omeprazole tablets. The two groups were intervened once a day, 4 weeks in total. The clinical efficacies in the two groups were compared based on the symptoms scores before and after the treatment.Result The total effective rate was 97.1% in the treatment group versus 85.2% in the control group, and the difference was statistically significant (P<0.05). The relapse rate 6 months after the treatment was 16.7% in the treatment group versus 50.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Reinforcing and reducing by acupuncturing at lower He-sea points along and against channel’s direction is an effective approach in treating GERD.
