Abstract: Objective To analyze the epidemiological characteristics of public health emergencies in Xishuangbanna Dai Autonomous Prefecture from 2012 to 2021, and to provide reference for formulating relevant prevention and control measures. Methods The data of public health emergencies reported in Xishuangbanna from 2012 to 2021 were collected and analyzed through the China Disease Prevention and Control Information System. Results A total of 78 public health emergencies (including "Unrated" events) were reported in Xishuangbanna from 2012 to 2021. The highest 21 cases and the lowest 3 cases were reported every year. A total of 1 0374 cases were reported in 78 public health emergencies, involving a population of 1 703 049, with a morbidity of 609.14/100 000, 24 deaths, mortality of 1.41/100 000 and fatality rate of 231.35/100 000. The event level was mainly "general (level Ⅳ)" with 52 incidents, accounting for 66.67%, and 17 incidents of "major (level Ⅲ)", accounting for 21.79%. 51 cases were mainly infectious diseases, accounting for 65.39%. The peak periods for incidents were May-July and November-February of the next year; there were 39 incidents in schools, accounting for 50%, followed by 20 incidents in families, accounting for 25.64%. The top three reported cases were food poisoning (32.05%), chicken pox 17 (21.79%) and dengue fever 10 (12.82%). Among the 24 deaths in public health emergencies, 22 were caused by food poisoning. Wild bacteria poisoning and alcohol poisoning were the main causes of food poisoning, accounting for 45.83% and 37.5% of the total deaths, respectively. Conclusion Infectious diseases, especially respiratory diseases and food poisoning are the focus of the prevention and control of public health emergencies in Xishuangbanna Dai Autonomous Prefecture, of which Schools and families should be pay close attention. Plague, a Class A infectious disease, caused by the bacterium Yersinia pestis has occurred in two inter-animal outbreaks in 10 years and spread to the population, which should be of great concern.

OBJECTIVE:
To realize the automated assessment of the levels of epiphysis of distal radius and ulna by support vector machine (SVM).
METHODS:
The X-ray films of the left wrist joints were taken from 140 teenagers aged from 11 to 19 years old as training samples. The levels of epiphysis of distal radius and ulna were divided into five developmental levels. Each level contained 28 samples. Another 35 cases were selected as independent verifying samples. SVM classification models of the five developmental levels of epiphysis of distal radius and ulna were established. The internal cross validation was made by leave one out cross validation (LOOCV), while the external validation was made by histogram of oriented gradient (HOG), and then the accuracy (PA) of testing results was calculated, respectively.
RESULTS:
The PA of SVM, LOOCV and HOG of distal radius epiphyseal level were 100%, 78.6%, and 82.8%, respectively; whereas the PA of SVM, LOOCV and HOG of distal ulna epiphyseal level were 100.0%, 80.0% and 88.6%, respectively.
CONCLUSION
The SVM-based automatic models of the growth stage of distal ra- dius and ulna appear to have certain feasibility, and may provide a foundation for software development of bone age assessment by forensic medicine.

Objective To study the distribution and related factors of curative care expenditure (CCE) of injury in Gansu Province in 2017. Methods Based on the "A System of Health Accounts 2011 (SHA 2011)", the curative care expenditure of injury in Gansu Province was calculated and analyzed. The five?stage stratified cluster sampling method was adopted to extract 149 medical and health institutions, 120 township hospitals (including community health service centers), 150 individual clinics and 600 village clinics (including community health service stations). The top?down allocation method was used to calculate the cost of injury treatment in Gansu Province, and the influencing factors were analyzed by multiple linear regression. Results In 2017, the CCE of injury in Gansu province was 3.831 billion yuan, and the expense in general hospitals was 2.708 billion yuan. Among them, the cost of lower limb injury and head injury were 1.090 and 0.847 billion yuan. People aged 40 to 69 years old spent 1.901 billion yuan on injury treatment, and the CCE of injury treatment for men and women were 2.422 and 1.409 billion yuan respectively. The results of multiple linear regression showed that hospitalization expenditure was significantly associated with length of stay, operation, hospital grade, age, payment method and gender (P<0.001). Conclusion The economic burden of injury in Gansu Province is relatively heavy, so it is necessary to focus on preventions for different groups and costly injury sites.

OBJECTIVETo explore the effect of Shoutai Pill (STP) containing serum on bioactivity behaviors of trophoblast cells in spontaneous abortion (SA) patients such as cell proliferation, invasion, migration and secretion.
METHODSTrophoblast cells in artificial abortion in normal pregnancy and SA patients were isolated and cultured in vitro, which were then treated with STP containing serum at various concentrations (5%, 10%, 20%, respectively). Blank serum was taken as the normal control group and dydrogesterone containing serum as the dydrogesterone control group. The proliferation, cycle distribution, invasion and migration capacity, and beta human chorionic gonadotropin (p-HCG) level were detected by methyl thiazolyl tetrazolium (MTT) colorimetry, flow cytometry (FCM), Transwell experiments, and ELISA, respectively.
RESULTSCompared with the normal control group, the activity of cell proliferation obviously decreased, ratios of apoptotic cells (SubGO/G1) and G2/M phase were obviously elevated, S phase cell ratio was obviously reduced (all P < 0.05). Transwell experiments indicated invasion and migration capacity obviously decreased, secreted beta-HCG level were obviously reduced after 72-h intervention (P < 0.05). Compared with the SA group, the activity of cell proliferation obviously increased, ratios of apoptotic cells and G2/M phase were obviously reduced, S phase cell ratio was obviously elevated, invasion and migration capacity were obviously enhanced, secreted beta-HCG level were obviously elevated after 72-h intervention in the dydrogesterone control group and each STP containing serum group (all P < 0.05). The activity of trophoblastic cell proliferation, S phase cell ratio, invasion and migration capacity, and secreted beta-HCG level were strengthened along with increased STP containing serum. Besides, the effects of 20% STP containing serum group were significantly superior to those of the dydrogesterone control group (P < 0.05).
CONCLUSIONSTP containing serum could dose-dependently enhance the proliferative activity of trophoblastic cells, invasion and migration capacity, secretion of beta-HCG, and reduce the apoptosis of trophoblast cells, which might be one of mechanisms for STP preventing and treating SA.
