ABSTRACT
Objective@#To investigate the prospective effects of the consumption of protein and animal foods before menarche on the age at menarche among Chinese girls.@*Methods@#This paper was based on the data collected in the China Health and Nutrition Survey(CHNS) from 1997 to 2015. A total of 683 girls aged 6 and over who had completed information on age at menarche, height, weight, per capita annual household income, maternal education level and participated in at least one complete dietary survey within 1 to 4 years before menarche were included. Urban-rural stratified multivariable linear regression model was used to examine the effects of protein and animal foods intake before menarche on Chinese girls age at menarche in urban and rural areas.@*Results@#After adjusted for total energy intake, body mass index standard deviation score and per capita annual household income, the consumption of meat before menarche was negatively associated with the age at menarche among rural Chinese girls(B=-0.003, P=0.00), but not among urban Chinese girls(B=0.002, P>0.05). Total protein, dairy, eggs and aquatic products intake before menarche were not associated with Chinese girls age at menarche in urban and rural areas(B=0.002, -0.001, 0.003, 0.000; 0.001, 0.001, -0.001, -0.003, P>0.05).@*Conclusion@#Higher intake of meat before menarche might lead to earlier menarche onset in rural Chinese girls. The consumption of total protein, dairy, eggs, and aquatic products before menarche did not affect the age at menarche in Chinese girls.
ABSTRACT
U.rhynchophylla is an important herb in Chinese medical treasure with the functions of calming endogenous wind and arresting convulsion,clearing away heat and calming the liver,for the treatments of hypertension,epilepsy and convulsion,crying with fear in children.This paper retrieved and collated 3,304 items of application information in the invention patents over uncaria before July,2016.Data of the basic sciences were collected from Chinese Science Citation Database (CSCD) and those of situation analysis of patents from Patent Online Analysis System of Chinese Academy of Sciences.Year,region,patented technology,patentee and key technology were involved and analyzed in the system for profound investigation of the current situation and developing trend of invention patent application over uncaria.It was found that trace elements and chemical composition beneficial to human health were receiving favors from the market with rapt attention focusing on patent applications.However,there were still major limitations in the application and the patent quality needed improving.In conclusion,further development and the utilization of uncaria presented promising prospects.
ABSTRACT
Objective To assess the local anatomy of the Jing Bi with high-frequency ultrasound, and to evaluate the clinical significance of high-frequency ultrasound in acupuncture. Methods A total of 206 healthy subjects were observed with the high-frequency ultrasound. Two common location points of Jing Bi were selected and acupunctured under guidance of high-frequency ultrasound. The sensation of subjects was observed. Brachial plexus diameter, distance between skin and membrana pleuralis, as well as the brachial plexus and the pleura were measured. Results The filiform needle tip to lung, lung tissue and the brachial plexus were all showed, and the brachial plexus diameter, distance between skin and membrana pleuralis, the distance between the brachial plexus and the pleura were obtained. The patients felt when the needle reached the membrane of brachial plexus. All subjects got feeling within 10 seconds after acupuncture, and no pneumothorax occurred. Conclusion The local anatomy of dangerous acupoints can be accurately observed with high-frequency ultrasound. High-frequency ultrasound has important value and significance for acupuncturing the dangerous acupoints.
