China Tropical Medicine 2022;22(09):874-
Abstract: Objective The tuberculosis data of students registered and reported in Xuzhou from 2016 to 2020 were analyzed to provide a basis for Xuzhou to formulate tuberculosis prevention and control measures in schools. Method The epidemiological characteristics of tuberculosis among students in Xuzhou from 2016 to 2020 were analyzed based on the data from Tuberculosis Information Management System and Xuzhou Statistical Yearbook 2021. Results From 2016 to 2020, a total of 574 student tuberculosis patients were registered in Xuzhou, with an annual average registration rate of 5.64/100 000. The reported incidence of tuberculosis among students in Xuzhou showed an increasing trend year by year (χ2trend=22.521, P<0.001). There were 365 males and 209 females, respectively, with a sex ratio of 1.75:1. The tuberculosis patients were mainly in the 15-19 years old group and 20-24 years old group. According to the statistical analysis by different levels of education, students from ordinary higher institutions accounted for 48.61% of the total number of confirmed cases, followed by senior high schools and secondary vocational schools, accounting for 20.91% and 14.46%, respectively. Preschool education had the lowest number of confirmed cases, accounting for 1.05%. There was significant difference in the reported incidence of tuberculosis among students at different educational levels (χ2=1 522.39, P<0.001). The highest incidence was reported in ordinary higher institutions, followed by senior high schools and secondary vocational schools, and the lowest incidence was reported in preschool education. Conclusion Xuzhou city school tuberculosis epidemic integral is on the rise, we should further strengthen tuberculosis control work of school tuberculosis prevention and control measures of implementation in the future, at the same time to strengthen school tuberculosis prevention knowledge propaganda and standardize the schools for disposal of tuberculosis epidemic situation. We should also further strengthen the newborn matriculation examination and students absent from class because of illness monitoring work.
2.Measurement of Chinese distal femur and its significances in total knee arthroplasty and prosthesis design
Chinese Journal of Tissue Engineering Research 2013;(43):7521-7526
BACKGROUND:It has become increasingly concerned by the industry to detailed understand the morphology of people’s knee joint, thus achieving personalized and gender differentiated total knee arthroplasty, in order to design the knee joint prosthesis that match the characteristics of Chinese people. OBJECTIVE:To measure and characterize the morphological parameters of distal femur of normal adult Chinese people by CT tomography and three-dimensional reconstruction, and to discuss the differences between male and female in morphology of distal femur. METHODS:Seventy normal Chinese adults (35 males and 35 females, aging from 21 to 60 years) received bilateral knee joint CT scan. The scanning images of distal femur which we needed were col ected and handled with three-dimensional reconstruction or Picasa 3.0 software for col ages and overlapping exposure. The posterior condylar angle, anterior condylar angle and trochlear angle were measured on the images that treated by the software, as wel as the transverse diameter of distal femur, lateral condylar height, and the ratio between them. RESULTS AND CONCLUSION:The mean posterior condylar angle of Chinese women was larger than that of Chinese men (P<0.05);the mean anterior condylar angle of Chinese men was larger than that of Chinese women (P<0.05);The transverse diameter of distal femur, lateral condylar height and the femoral surface ratio (diameter/epicondyle height) of Chinese men were larger than those of Chinese women (P<0.05). The results showed that differences exist in morphology of distal femur between Chinese and western people. Also, the differences exist between male and female in Chinese people. These differences should be concerned in the design of femoral prosthesis for Chinese people as wel as in selecting and placing of femoral prosthesis before or during the total knee arthroplasty.

The nature and functions of astrocytes (AS), the pathological changes and roles of AS after spinal cord injury, the experimental methods of inhibiting AS proliferation and glial scar formation, and so on, were reviewed. AS beneficially affects repairing injured spinal cord at different periods of differentiation. However, adult AS secreting the factors formed the chemical glial barrier which severely affects nerve regeneration and hinders axon extension. Because of the static, activated and proliferative AS tending to coexist after spinal cord injury, and complex factors of barrier formation, the current approach taken by a single method is difficult to effectively control the AS proliferation and glial scar formation.

OBJECTIVE:To analyze the constituents of volatile oil in Artemisia indica from different area of Guangxi, and to compared which with those in Artemisia argyi. METHODS: The volatile oil was extracted from Artemisia indica and Artemisia argyi respectively by steam distillation. The constituents of the volatile oil were identified by GC-MS technology. RESULTS: The yield of the collected volatile oil of Artemisia indica from different area of Guangxi was 0.32%~0.67%, and compared with Artemisia argyi, both were found to contain the following main constituents: eucalyptol, camphor, borneol, germacrene D, caryophyllene, caryophyllene oxide, terpineol, azulene etc. But the content of the same constituents in Artemisia indica varied with different producing area and there was also difference for a certain constituent of the volatile oil. CONCLUSION: The study results serve as a scientific basis for rational use of Artemisia indica from Guangxi.

Objective To discuss the influential factors of postoperative pulmonary complications in elder patients accepted abdominal operation. Methods The clinical data of 95 cases accepted abdominal operation were analyzed retrospectively,and all the patients aged over 60. These patients were divided into two groups based on whether they had pulmonary complications or not. Seven relative factors including the age,sex,smoking history,surgery duration ,operation place,pulmonary function,anesthesia were analyzed and the relationship between these factors and the incidence of postoperative pulmonary complications were explored,too. Results Among the 95 patients,19 cases had pulmonary complications. The surgery duration in patients with pulmonary complications ((3.4 ± 1.1)h)were significantly higher than in those without pulmonary complications ((2. 6 ± 0. 9)h)(P <0.05). We also found significant differences in the comparison of FEV1%(59.2 ±9.5),FEV1/FVC(61.3 ±7.7)% ,MVV%(59.3 ±8.6)% in the group with pulmonary complications,with FEV1%(79.7 ± 11.5)%、FEV1/FVC(73.2 ±8. 3)% 、MVV%(74. 2 ±6. 4)% in the group without pulmonary complications. The epigastric operation and general anesthesia before operation were risk factors for post-operative pulmonary comphcations(P <0. 05). Conclusions Surgery duration,operation place,pulmonary dysfunction and anesthesia may be the risk factors of pulmonary complications after abdominal operation.
