Objective: To investigate the changing trends in injury mortality among permanent residents in Jingzhou City, Hubei Province from 2017 to 2022, so as to provide the basis for formulating injury intervention measures. Methods: Injury death data of permanent residents in Jingzhou City from 2017 to 2022 were collected through the Population Death Information Registration and Management System of Chinese Disease Prevention and Control Information System. The crude mortality of injury was analyzed and the standardized mortality was calculated using the data from the Sixth National Population Census in 2010. The changing trend in injury mortality was analyzed using the annual percent change (APC). Results: There were 29 220 injury deaths among permanent residents in Jingzhou City from 2017 to 2022, with a crude mortality rate of 88.61/105. The crude mortality rate of injury was higher in males than in females (101.04/105 vs. 75.97/105, P<0.05). The crude mortality rates of injury in males, females and the whole population all showed upward trends (APC=6.572%, 9.232% and 7.731%, all P<0.05). Males, females and the whole population at the ages of 65 years and above appeared upward trends in crude mortality rates of injury (APC=4.603%, 5.064% and 4.851%, all P<0.05). No significant trends were observed in the crude mortality rate in the residents aged <15 years and 15 to <65 years (both P>0.05). The top five causes of injury death were suicide (25.81/105), falls (24.38/105), motor vehicle traffic accident (17.23/105), drowning (8.61/105), and other unintentional accidents and harmful effects (5.63/105). From 2021 to 2022, falls rose to the first cause of injury mortality. Conclusions The crude mortality of injury among permanent residents in Jingzhou City from 2017 to 2022 showed an upward trend. Males and residents aged 65 years and above should be prioritized for intervention measures. Notably, falls have become the top cause of injury from 2021 to 2022.

Objective To observe the influence of local-anaesthetic combined with dezocine on brachial plexus block and postoperative analgesia.Methods 60 patients scheduled for unilateral upper limb operation were randomly divided into two groups of C group and D group with 30 cases in each group.The brachial plexus block was performed under ultrasound guiding.Two groups received a bolus injection of local anesthetic 30ml,but the local bolus injection of D group consisted of Dezocine 10mg.The tine of sensory blocked producing effect,anesthesia effect,sensory blocked duration were observed.Two hours after sensory nerve recovered,the scores of VAS pain and Ramsay Sedation were recorded.Adverse reactions of perioperation were also observed(nausea,vomiting,dizzy,respiratory,urine retention,pruritus).Results The sensory blocked duration in D group was(7.1±1.1)h,which was significantly longer than that of C group[(4.5±0.8)h](t=10.47,P＜0.01);Two hours after sensory nerve recovered,the score of VAS pain in D group was(1.7±0.7)points,and significantly lower than that of C group[(3.9±1.0)points](t=9.87,P＜0.01).Both two groups had no adverse reactions.Conclusion Addition dezocine 10mg to local anesthetic solutions for interscalene brachial plexus block,it could prolong the sensory block duration,provide satisfactory postoperative analgesia,have no adverse reactions.

The contents of coumarins in the sulfur fumigated Angelicae Dahuricae Radix (Baizhi, ADR) were reduced significantly. To achieve the quality control of ADR, the qualitative identification of sulfur fumigated ADR and quantitative model of imperatorin content should be established. The near-infrared (NIR) spectrograms of non-sulfur and sulfur fumigated ADR were collected by NIR diffuse reflectance spectroscopy technology and pretreated by the method of first derivative derivation and vector normalization. The Ward's Algorithm method was used for the cluster analysis. The non-sulfur and sulfur fumigated ADR can be quickly identified in the range of 8,806. 0-3 811.0 cm(-1) based on the cluster analysis. The NIR quantitative model of imperatorin was established by the contents of imperatorin determined by HPLC in combination with partial least squares regression analysis. According to the calibration model established in this study, correlation coefficients (R2), the root-mean-square error of cross-validation (RMSECV), and the root-mean-square error of prediction (RMSEP) for imperatorin were 0.982 8, 0.006 8, 0.011 8, respectively. The quantitative model of imperatorin can be applied to determine the content of imperatorin in ADR accurately.
