ABSTRACT
Objective@#To explore the epidemic characteristics of injury related deaths in children and adolescents aged 1-24 years old in China from 2010 to 2020, so as to provide a basis for the formulation of policies and measures related to the control of injuries and deaths among children and adolescents.@*Methods@#The data were sourced from the China Death Cause Monitoring Dataset from 2010 to 2020. Annual percentage change (APC) and average annual percentage change (AAPC) of injury deaths in China in this age group during the period 2010 to 2020 were analyzed by Join point regression.@*Results@#From 2010 to 2020, the standardized death rate of injury showed a decreasing trend (AAPC=-6.90%, t =4.58, P <0.01). The standardized death rates of male and rural injuries showed an overall downward trend, with AAPC rates of -8.37% and -7.79%( t =11.87, 10.34, P <0.01). An increasing trend was observed in the 20-24 year-old age group during 2010-2018 (APC=18.11%, t =6.50, P <0.01). The death rate from injuries was higher in males than females, and higher in rural areas compared with urban areas ( χ 2=16 483.64, 3 268.65 , P <0.01). A downward trend was observed in accidental falls and suicide, the overall standardized mortality rate of traffic accidents, accidental poisoning, fire, drowning, homicide and other injuries (AAPC=-10.22%, -6.21%, -7.50%, -7.94%, -9.01% , -10.97%, t =16.23, 7.29, 2.53, 9.32, 7.88, 4.58, P <0.05). @*Conclusion@#From 2010 to 2020, the overall injury standardized mortality rate in the 1-24 year-old age group shows a decreasing trend, but it remains at a relatively high level. Prevention efforts should be continuously strengthened, especially for urban areas, and should focus on women and those aged 20-24 years old, as well as accidental falls and suicide prevention.
ABSTRACT
@#Objective To introduce a new type thoracic vest designed according to the incision characteristics of female patients undergoing totally thoracoscopic cardiac surgery. Methods Sixty-one female patients undergoing totally thoracoscopic cardiac surgery from February 2019 to May 2020 in our department were enrolled. All female patients had hypermastia and (or) mastoptosis which covered the incision. They were randomly divided into a research group (group A, n=32) and a control group (group B, n=29). The group A used the new type thoracic vest, while the group B used the traditional single shoulder belt. The degree of satisfaction, visual analogue scale (VAS) score 24 hours after the thoracic drainage tube removed, the average time-consuming of dressing change, dressing frequency and the incision infection rate were compared between two groups. Results The degree of satisfaction in the group A was higher than that of the group B (P<0.001). The VAS scores of pain, average time-consuming of dressing change and dressing frequency in the group A were less or lower than those of the group B (P<0.001). There was no statistical difference in the incision infection rate between the two groups (P=0.214), but incision infection rate of the group A was lower than that of the group B. Conclusion The new type thoracic vest seems to be more beneficial for patients than traditional single shoulder belt. It is easy to use, increases the psychological satisfaction of patients, reduces the pain and the incision infection and improves work efficiency, which is worthy of clinical application.

ABSTRACT
<p><b>OBJECTIVE</b>To establish a GC-MS fingerprint profile of the volatile oil in mulberry leaves (dried leaves of Morus abla) in order to provide the referent basis of quality evaluation.</p><p><b>METHOD</b>The volatile oil was extracted from mulberry leaves by water stream distillation method, 10 bathes of samples collected from different regions were analyzed by GC-MS, and their GC-MS fingerprint were subsequently established. Hierarchical clustering analysis was performed by SPSS software.</p><p><b>RESULT</b>Seventeen common characteristic peaks were summarized from the fingerprint of the 10 baths of mulberry Leaves sample, which were clasified two categories by the result of hierarchical clustering analysis, namely samples collected in Akesu area, Tulufan area, Hami area, Hetian Loupu county, Jiangsu province, Sichuang province, Shanxi province and Guangzhou were in a group, whereas those from Yili area and Wulumqi were in another group.</p><p><b>CONCLUSION</b>The established GC-MS fingerprint could be used for the identification and quality evaluation of mulberry leaves, the method was accurate and reliable, the fingerprint was intuitive and specific.</p>
