Objective To investigate the effect of self decoction wet compress on puncture venous sclerosis.Methods 180 patients received intravenous therapy,they were randomly divided into group A,group B and group C,60 cases in each group.Group A was given with Traditional Chinese medicine decoction(rhubarb 20g,Xuan Ming powder 20g,Cortex Phellodendri 15g,20g purslane fried together) for in the direction of blood vessel along the direction of the blood vessel after operation of conventional intravenous infusion,8 layer 10cm×5cm sterile gauze soaked wet,then covered with plastic wrap plastic to the end of infusion 30 min after removal.Group B was given with Traditional Chinese medicine decoction at the end of intravenous infusion at the puncture point along the direction of the blood vessels,8 layer 10cm×5cm sterile gauze soaked wet and then with plastic wrap plastic cover 6h after removing.Group C was given with routine intravenous infusion operation without wet compress intervention.In 3d,5d,vein elasticity of each group was assessed,the normal was effective,mild,moderate and severe hardening was invalid.Results After 3d,5d treatment,the effective rates of group A were 100.0%,91.7% respectively,which in group B were 100.0%,81.7%,respectively,the effective rate at 5d had statistically significant difference between group A and group B (x2=5.17,P<0.05);after 3d,5d treatment,the effective rates of group C were 71.7%,60.0%,and the effective rate at 5 d had statistically significant difference compared with group B and group A (x2=21.07,6.82,all P<0.01).Conclusion The effect of intravenous infusion process to local decoction wet compress on the prevention of venous puncture hardening is significant,and the method is simple,has non-toxic side effects,it is worthy of clinical application.

OBJECTIVEThis study aimed to explore the secular trends of overweight and obesity prevalence between 2007 and 2011 in children and adolescents in Guangzhou.

METHODSThe data of physical examination was collected from the routine measurements carried out by the Health Care Facilities of Primary and Secondary schools between 2007 and 2011. Random stratified cluster sampling was conducted, all the students aged 5-18 years old form 19 primary and secondary schools from 4 districts (Tianhe district, Yuexiu district, Baiyun district and Haizhu district) were included in this survey, including 27 944 students in 2007 and 38 284 students in 2011. Body mass index reference norm established by Working Group on Obesity in China (WGOC) and the WHO cut-off criteria were employed for overweight and obesity screening, and the trend was analyzed.

RESULTSPrevalence of obesity in children and adolescents (7-18 years old) significantly increased from 5.96% (1 553/26 055) in 2007 to 6.56% (2 339/35 664) in 2011, and the difference showed statistical significance (χ(2) = 9.195, P < 0.05). Overweight and obesity was more common in boys (overweight: 13.25% (1 766/13 329) in 2007 and 13.87% (2 559/18 451) in 2011; obesity: 7.82% (1 042/13 329) in 2007 and 8.63% (1 592/18 451) in 2011) than in girls (overweight: 7.43% (946/12 726) in 2007 and 8.17% (1 406/17 213) in 2011; obesity: 4.11% (523/12 726) in 2007 and 4.48% (771/17 213) in 2011), and the difference showed statistical significance (overweight:χ(2) = 236.123 in 2007 and χ(2) = 292.892 in 2011; obesity:χ(2) = 158.533 in 2007 and χ(2) = 247.794 in 2011. All P values < 0.05). Further analysis found that significant increases occurred in boys aged 16 and 17 years old and in girls aged 12 years old (boy: 16 years old,χ(2) = 6.820, P < 0.05. 17 years old, χ(2) = 4.893, P < 0.05. girl: 12 years old,χ(2) = 5.921, P < 0.05).

RESULTSof Join-point regression showed that for boys less than 10 years old the prevalence increased with age increasing (in 2007, APC = 3.75; in 2011, APC = 1.76), while over 10 years old the prevalence decreased with age increasing (in 2007, 10-18 years old's APC = -18.58; in 2011, 10-18 years old's APC = -15.95). While for girls the prevalence of obesity increased with age increasing between 7-9 years old (APC = 12.16), decreased with age increasing through 9 to 18 years old (APC = -17.23) in 2007. The prevalence decreased with age increasing for girls in 2011 (APC = -4.66).

CONCLUSIONThe prevalence of obesity is high and still increasing in children and adolescents in Guangzhou, and it is higher in boys than in girls. It is more likely to become obesity at 10 years for boys, and for girls the prevalence decrease with age increasing.
