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.

Facing the current situation of cultivation of humanistic quality of medical students,the affiliated hospital has the necessity and possibility to deeply involve the cultivation of medical students' humanistic quality.Its profound historical and cultural accumulation,a large number of advanced figures and humanistic care system are conducive to the cultivation of humanistic quality of medical students.This paper put forward the establishment of the working group on the cultivation of humanistic quality,the multi-level humanistic curriculum teaching,the motivation of teachers in hospital,the evaluation and assessment of medical students' humanistic quality,and the formation of the combination mode of hospital and medical college in the cultivation of medical student's humanistic quality,are the effective way of strengthening the deep involvement of affiliated hospital in the cultivation of medical students' humanistic quality.

There are some problems in the definitions of 'interaction between the heart and the kidney' and 'non-interaction between the heart and the kidney' made in the teaching material of traditional Chinese medicine used by western medicine institutes,colleges and universities.In the teaching material,it explains 'interaction between the heart and the kidney' as the relation between heart fire and kidney water,and 'non-interaction between the beart and the kidney' as the relation between heart-yin and kidney-yin.If we cannot correctly understand the pathogenesis of 'non-interaction between the heart and the kidney',we will fail to determine the concrete treatment method for ' coordinating the heart and the kidney'.Through the analysis and discussion on the theory,clinical syndrome,therapeutic principles and prescriptions for the syndrome of disharmony between the heart and the kidney,the authors draw the conclusion that the therapy for this disease should be determined according to the excess and deficiency of the heat fire and kidney water.For instance,if the deficient kidney water cant ascend to coordinate with the heart and results in exuberance of heart fire,Huanglian Ejiao decoction should be used; in the other situation,if the exuberant heart-fire can't descend to coordinate with the kidney and results in deficiency of kidney yang,Jiaotai Pill should be used.The theoretical results could standardize textbook and give better service to the clinical education.

Brain tumor stem cells (BTSCs) play a key role in tumorigenesis and tumor development.There are a group of special markers in the surface of brain tumor stem cells,which can sorts stem cells,precursor cells and cancer stem cells.In recent years,the studies of CD133,Nestin,high-mobility group A1,A2B5 have made some breakthroughs.

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.

Objective To investigate the effect of curcumin (Cur)on acute lung injury (ALI) induced by one-lung ventilation (OLV)in mice.Methods Sixty C57BL/6J mice were randomly alloca-ted into six groups (n =10):two-lung ventilation group (TLV group),OLV group,OLV+Cur pre-treated with 50 mg/kg group (Cur50 group),100 mg/kg group (Cur100 group),1 50 mg/kggroup (Cur1 50 group)and200 mg/kg group (Cur200 group).Peak and averaged airway pressure (Ppeak and Paw)of mice in each group were recorded.Mice were euthanized and the end of experiment,and left lung tissue was excised.Wet lung weight to dry lung weight (W/D)and total lung water content (TLW)were tested.Pathological changes of lung tissue were observed under light microscope,and changes of ultrastructure of lung tissue were observed by transmission electron microscope.Index of quantitative evaluation for alveolar damage (IQA)and lung injury scores were tested under light mi-croscope.The expression of c-Jun N-terminal kinase (JNK)mRNA and phosphorylated JNK (p-JNK)protein were detected respectively by reverse transcription-polymerase chain reaction (RT-PCR)and Western Blot.Apoptosis index (AI)of lung tissue was determined by terminal dexynucle-otidyl transferase(TdT)-mediated dUTP nick end labeling (TUNEL)method.Results There was no statistical significance at Ppeak and Paw of rats in each group.Compared to TLV group,the expres-sion of JNK mRNA and p-JNK protein were all significantly increased (P <0.05)in OLV group,and W/D,TLW,IQA,lung injury scores and AI were all notably higher (P <0.05);morphological and ultrastructural injuries in lung tissue were notably occured in OLV group.Compared to OLV group,the expression levels of JNK mRNA and p-JNK protein were decreasingly lower (P <0.05 )in the groups of Cur100,Cur1 50 and Cur200,W/D,TLW,IQA,lung injury scores and AI were also de-creased (P <0.05);morphological and ultrastructural injuries in lung tissue were gradually alleviated in the groups of Cur100,Cur1 50 and Cur200.However,there was no statistical significance in the in-dexes mentioned above between Cur50 group and OLV group.Conclusion Cur at doses of 100 to 200 mg/kg has protective effects on lung against OLV injury in mice,which may be related to inhibition of pneumocyte apoptosis induced by JNK.

OBJECTIVE:To observe the clinical efficacy and safety of Enalapril folic acid tablet combined with Shenkang injec-tion in the treatment of hypertensive nephropathy. METHODS:90 patients with hypertensive nephropathy were randomly divided in-to control group and observation group. All patients were given anti-infection,regulating electrolyte balance,supplying amino acids and other conventional treatment. Based on it,control group was orally given Maleic acid enalaprilat folic acid tablet 1 tablet in the morning,once a day;observation group was additionally given 100 ml Shenkang injection adding into 300 ml 10% Glucose injec-tion by intravenous infusion,20-30 drops/min,once a day. The treatment course for both groups was 4 weeks. The clinical effica-cy,and clearance rate of creatinine(Ccr),serum creatinine (Scr),morning urine test urine protein (Up)/urine creatinine (Ucr), serum malondialdehyde(MDA),superoxide dismutase(SOD),total antioxidant capacity(T-AOC)before and after treatment and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,the Ccr,SOD and T-AOC in 2 groups were significantly higher than before,and observation group was higher than control group,Scr and MDA were significant-ly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). Morning urine test Up/Ucr,systolic blood pressure and diastolic blood pressure were significantly lower than before,and the differ-ences were statistically significant(P<0.05),however,there was no significant difference between 2 groups(P>0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Based on the conventional treat-ment,Enalapril folic acid tablet combined with Shenkang injection has better efficacy than only Enalapril folic acid tablet in the treatment of hypertensive nephropathy,with similar safety.
