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.

Objective To investigate the distribution of pathogenic bacteria of vaginal discharge in bacterial vaginosis.Methods The results of bacterial culture and drug sensitive tests of vaginal discharge from patients with bacterial vaginosis were analyzed.Results The positive rate of bacteria culture of vaginal discharge was 79.3%(115/145).The dominant bacteria were staphylococcus epidermidis 27.0%(31/115),staphylococcus intermedius and staphylococcus aureus 13.0%(15/115),which were obviously higher than other germs.The drug sensitive tests showed that staphylococcus were relatively sensitive to vancomycin,fosfomycin,amikacin and rifampin.But the drug resistance to penicillin,tetracycline,erythromycin and oxacillin was the highest.Conclusion The kinds of pathogenic bacteria in vaginal discharge are various.The main bacterium is staphylococcus,and drug resistance is very severe.The isolation and drug sensitive test of pathogenic bacteria play an important role in diagnosis and treatment of gynecological disease.

Objective To evaluate the movement function of the left ventricular short-axis with parameters (velocity, acceleration and relatively force) measured with improved anatomical M-mode ultrasound. Methods Sixteen patients with myocardial ischemia coronary heart disease who had taken percutaneous transluminal coronary intervention (PCI) were enrolled. All patients were divided into two groups: group A, single major vascular stenosis (n=8);group B, more major vascular stenosis (n=8). M-mode curves of short-axis sections at mitral valve level, papillary level and apical level were recorded, then the peak myocardial velocities, acceleration and force of the systolic phase, early-diastole phase and end-diastole phase were measured at the post processing station. Results The variety ranges of average velocity and acceleration of the three levels during systolic phase were higher than that during diastole phase. The changing rate of velocity and acceleration in group B was higher than that in group A. Conclusion The new parameters that are measured and calculated with anatomical M-mode ultrasound can reflect the movement functions of coronary heart disease patients taken PCI.

Objective To investigate the correlation between ABCD2 scores and vertebrobasilar artery stenosis in patients with posterior circulation transient ischemic attack (TIA).Methods The patients with posterior circulation TIA who performed cerebral angiography were enrolled in the study,and their ABCD2 scores and imaging data were analyzed.Results A total of 108 patients with posterior circulation TIA were enrolled.There were significant differences in the main trunk stenosis degree of vertebrobasilar artery with different ABCD2 scores in patients with posterior circulation TIA (P =0.005).The overall degree of stenosis increased with the increase of ABCD2 score (P =0.000).After adjustment for other vascular risk factors,ABCD2 score had significant predictive ability for whether had posterior circulation stenosis (odds ratio [OR]1.771,95％ confidence interval [CI] 1.234-2.542; P =0.002) and moderate to severe stenosis (OR 2.083,95％ CI 1.336-3.176; P =0.001).Its receiver operating characteristic area under the curve was 0.693(95％ CI 0.586-0.800) and 0.755 (95％ CI 0.661-0.849) respectively.When the ABCD2 score was ≥3,the sensitivity and specificity of predicting posterior circulation stenosis were 62.6％ (95％ CI 53.4％-71.7％) and 70.6％ (95％ CI62.0％-79.1％) respectively,and the sensitivity and specificity of predicting posterior circulation stenosis ＞ 50％ were 78.7％ (95％ CI 70.9％-86.4％) and 67.5％ (95％ CI58.7％-76.3％) respectively.Conclusions In patients with posterior circulation TIA,the stenosis degree of vertebrobasilar arterial trunk increases with the increase of ABCD2 score.In a certain extent,ABCD2 score may predict whether the main trunk of the posterior circulation has stenosis and whether has moderate to severe stenosis.

OBJECTIVE:To establish a method for the determination of weight average molecular weight(Mw)and molecular weight distribution (D) of ferric carboxymaltose. METHODS:HPGPC method was adopted to detect the Mw and D of 3 batches of Ferric carboxymaltose injection (imported) and its raw material (self-made). The determination was performed on TSK G4000 PWXL column with 0.1% sodium azide solution with the flow rate of 0.5 ml/min. The detector was refractive index detector;the column temperature was set at 35 ℃,and sample size was 20 μl. The results were calculated with GPC software. RESULTS:RSDs of precision,stability and reproducibility tests were all lower than 3.0%(n=6);Mw and D of 3 imported samples were 157 667 and 1.30;those of self-made samples were 162 000 and 1.42. CONCLUSIONS:The method has high precision,good stability,repeat-ability and durability. It can be used for the determination of Mw and D of ferric carboxymaltose.

Objective To analyse the difference between stage Ⅰ pure bronchioloalveolar carcinoma (BAC) and stage Ⅰ adenocarcinoma of the lung among operative cases.Methods We use the Lobectomy Cases Registration and Statistics System database (2006-2011) to compare the epidemiology,clinical presentation,image characteristics,surgical outcomes,recurrence and overall survival between BAC and adenocarcinoma groups.All the patients received lobectomy procedure in the department of thoracic surgery of Peking University People' s Hospital.Results Excluding those cases with both BAC and adenocarcinoma aspects,337 patients were enrolled.Thirty-nine patients were stage Ⅰ pure BAC and 298 patients were stage Ⅰadenocarcinoma.BAC has its proper clinical spectrum,occurring more frequently in women (69.2％ vs.52.0％,P =0.042)and in younger patients (57.4 vs.61.8,P =0.014).BAC also seems to be less dependent on tobacco exposure (12.8％ vs.29.9％,P =0.026).The percentage of ground-glass opacity (GGO) in CT scan of BAC patients was much more than that registered in adenocarcinoma patients (35.9％ vs.9.7％,P ＜0.001).And the tumor size of BAC group was smaller than that of the adenocarcinoma group (1.4 cm vs.2.3 cm,P ＜0.001).The operation method,time,blood loss and complications were similar between the two groups.Kaplan-Meier survival curves showed that both 3-year disease-free survival (DFS) and overall survival (OS) were significantly higher in patients affected by BAC (100％ vs.76.1％,P =0.030 and 100％ vs.86.1％,P =0.041).Conclusion BAC presents specificity in its epidemical,clinical,radiological and evolutionary aspects.Stage Ⅰ pure BAC patients have better prognosis following video-assisted thoracoscopic lobectomy and system lymph node dissection than the similar stage adenocarcinoma patients.
