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.

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 investigate the method and curative effect for the operative treatment of acetabular fractures.Methods Forty-one patients with acetabular fractures were treated operatively from March 2001 to March 2006.All fractures were classified according to the Letournel-Judet classification,22cases were simple fractures and 19 cases were complicated fractures.Kocher-Langenbeck (K-L) approach were adopted in 31 cases (14 cases through osteotomy of greater trochanter additionally),ilioinguinal approach were adopted in 8 cases and anterior combined posterior approach were adopted in 2 cases.Different fractures were fixed by reconstructive plates and screws.Results All the patients were followed up for 16-36 (24.31 ± 5.31 ) months.According to the reduction criteria of Matta radiography,there were 27 cases with anatomic reduction,8 cases with satisfactory reduction,3 cases with poor reduction and 3 cases with joint contour reduction.According to the Merle D' Aubigne clinical criteria for joint functions,14 cases showed excellent results,18 cases were good,5 cases were fair and 4 cases were poor,and the excellent-good rate was 78%( 32/41 ).Necrosis of the femoral head was found in 3 cases,heterotopic ossification in 4 cases,traumatic arthritis in 3 cases,sciatic nerve injury in 4 cases,femoral nerve injury in 1 case,all the nerve injury recovered in 6 months.Lower extremity deep venous thrombosis in 3 cases,all of them were recovered by given anticoagulation.No death,infection or nonunion were found.Conclusions K-L approach or ilioinguinal approach are adopted in the most of the operative treatment of acetabular fractures.Dual reconstructive plates or single.reconstructive plate combine lag screws can fix solid.It can make hip to do early exercise.

Objective To investigate the related factors of postoperative pulmonary complications with abdominal operation. Methods 193 cases after abdominal operation were reviewed. The age, smoking history, surgery duration, surgical site, pulmonary function, artery blood gas analysis, and the incidence of post-operative pulmonary complications were analyzed. Results Pulmonary complications were found in 29 cases. The age was higher and surgery duration was longer in patients with pulmonary complications than those without pulmonary complications (P<0.05). The patients with abnormal forced expiratory volume in the first second (FEV1)%, FEV1/ forced vital capacity (FVC)%, maximum ventilatory volume (MVV)% and smoking history before operation were in higher risk for post-operative pulmonary complications (P<0.05). There was significant difference in artery blood gas analysis between the 2 groups (P<0.05). Conclusion The age,smoking history, surgery duration and pulmonary dysfunction may be the risk factors of pulmonary complications after abdominal operation,while it is important to monitor the blood gas analysis.

Objective To study the characteristics of complement expression and the effects of atorvastatin on the complement in rats after the cerebral ischemic infarction.Method One hundred and sixty adult healthy Sprague-Daweley rats were randomly divided into normal group,sham-operated group,ischemia group and treat group.The ischemia group and treatment group were sub-devided into 6 h,12 h,24 h,48 h,3 d,5 d,2week,respectively.The middle cerebral artery occlusion(MACO)model was induced by using filament method,and the thread Was withdraw from the middle cerebral artery after occlusion 2 h.Rats in the sham-operated groupdid not have thread inserted.After wakefulness,the animals The successful of animal model produced was evidenced by the paralysis of contralateral limbs.The animals model in the treatment group treated with Atorvastatins 10 mg once a day for 2 weeks and,rats in the ischemia group did not receive Atorvastatin.The neurological deficit scoring was measured at different intervals in the ischemia and treat ment groups.The expressions of complement C1q and C3 d protein in the brain of the rats in 4 groups were measured by immunohistochemical methods.Result There were a few complement expression in the brain of normal rats,showing no significant difference observed between sham-operated group and normal group(P＜0.05).The complements(C1 q and C3 d)expressied increasubgkt after cerebral ischemia injury,peaked 24 h after ischemia,and returned to normal levels 5 d after ischemia.The expression of complement C1 q and C3 d in the ischemia group were significanfly higher than those in sham-operated group(P＜0.05),The expression of complement C1 q and C3 d in treat ment group were signnificantly lower than those in the ischemia group(P＜0.05).The neurological deficit score in treatment group were signnificantly lower than that of ischemia group.Conclusions The expressions of complement C1 q and C3 d were increase gradually after cerebral ischemia in the rats,Atorvastatin Can inhibit the complement activation,improve neuro logical function of rats.
