ABSTRACT
Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2011 to 2019, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of mumps in Guangxi from 2011 to 2019. Results From 2011 to 2019, a total of 146,132 cases of mumps were reported in Guangxi, with an average annual incidence rate of 34.23 /100 000. There were 88,919 male cases (60.85%) and 57,213 female cases (39.15%). The incidence rate decreased from 62.26/100 000 in 2011 to 16.46/100 000 in 2015, and increased from 18.60/100 000 in 2016 to 46.90/100 000 in 2019. There were seasonal variations in the incidence, with the incidence peaks occurring from April to July and from October to the following January. 85.39% of cases were under 15 years of age, and 76.82% of cases were among kindergarteners or school children. A total of 228 mumps outbreaks were reported during 2011-2019，including 5,347 cases, accounting for 3.66% of the total cases. The incidence rates of mumps in Nanning (56.09/100 000), Hechi (48.26/100 000), Liuzhou (46.77/100 000), Baise (46.34/100 000) and Fangchenggang (40.68/100,000) were relatively higher than other places. Conclusion The mumps incidence is on an upward trend in Guangxi since 2015-2019, occurring mainly in older children or students. It is suggested to adhere to the second dose of mumps containing vaccine for kindergarten and school children and strengthen the surveillance and outbreak control of mumps in schools.
ABSTRACT
OBJECTIVE: To investigate the effect of innovative artificial ligament material on reconstruction of cruciate ligament. METHODS: A total of 18 studies about clinical reconstruction of cruciate ligament by using artificial ligament material were retrieved with the keywords of artificial ligament, scaffold material, cruciate ligament, and reconstruction in CNKI from 1990 to 2008. Subjects were generally analyzed in clinic, while clinical application of artificial ligament material was summarized based on follow up and functional evaluation. RESULTS: A total of 18 studies about clinical application of artificial ligament material for reconstruction of cruciate ligament indicated that there were no significant differences in age, sex, and injured types. Lysholm and IKDC scoring standard indicated that LARS artificial ligament was satisfactory for reconstruction of cruciate ligament. CONCLUSION: Arthroscope indicates that LARS artificial ligament is characterized by stably recovering function of knee joint, less trauma, less complication, and well short-term therapeutic effect; however, the long-term effect of LARS on reconstruction of cruciate ligament still needs to be further studied.
