Objective To analyze and evaluate the implementation effect of tuberculosis prevention and control program in Wuhan, and to provide reference for scientific formulation of tuberculosis prevention and control measures. Methods Using the National Tuberculosis Information Management System, descriptive statistical analysis was carried out on the medical record information of pulmonary tuberculosis patients registered in Wuhan , 2016 - 2021. Results A total of 34 937 cases of pulmonary tuberculosis were registered in Wuhan , with an average annual incidence rate of 49.85/100 000. The incidence rate showed a downward trend year by year, with a statistically significant difference in 2016—2021 (χ²_trend = 708.387, P<0.001). The patients mainly came from referrals, accounting for 71.86%, and the proportion of referrals varied significantly among different years (χ²=355.541, P<0.001). The diagnosis type was mainly pathogenic negative, accounting for 49.12%. The proportion of pathogenic negative had statistically significant difference among different years (χ²=1 354.830, P<0.001). The proportion of patients cured and completed the course of treatment reached 93.98%, with statistically significant differences in the proportions among different years (cured, χ²=1 080.252, P<0.001; completed the treatment course, χ²= 933.655, P<0.001). The sputum examination rate of newly diagnosed patients in each year reached over 90%, and the overall completion rate reached over 95%. The proportion of positive pathogens showed an increasing trend year by year. Conclusion The overall epidemic situation of tuberculosis in Wuhan is declining year by year, and tuberculosis prevention and control work has achieved remarkable results. Active screening in key areas and populations should be strengthened, and prevention and control strategies should be formulated by emphasizing the key and difficult points.

Objective:To summarize the electroclinical characteristics of patients with epilepsy with myoclonic absence（EMA）and analyze the relationship with prognosis.Methods:Clinical data of 25 patients with EMA monitored at the pediatric EEG monitoring centers of Peking University People's Hospital and Peking University First Hospital between January 2012 and December 2022 were retrospectively analyzed and divided into three groups according to development before and after the onset of the disease to analyze the electroclinical characteristics and the relationship with prognosis.Results:There were 14 males and 11 females in 25 cases，and the median age of epilepy onset was 48（26，74）months.Sixteen cases in the group with normal development before and after the onset of epilepsy（group A），5 cases in the group with normal development before the onset of epilepsy but retarded development after the onset of epilepsy（group B），and 4 cases in the group with retarded development before and after the onset of epilepsy（group C）.The median age at onset was 62（36，82）months，34（21，66）months，and 26（20，32）months in the three groups，with 3，3，and 4 cases of early onset in each group，respectively.The EEG background activity slowed down in 10 cases，with 6，1 and 3 cases in the three groups，respectively.Interictal EEG was normal in 1 and abnormal in 24 cases，which showed generalized discharges，of which 11 cases showed coexisting focal discharges and generalized discharges.Among the focal discharges，there were cases in all three groups，involving the anterior-posterior，temporal and Rolandic regions.Fifteen cases had myoclonic absence（MA）induced by hyperventilation，with 10 cases in group A，4 cases in group B and 1 case in group C.The most prevalent concomitant seizure was myoclonic seizure（MS），with 9，3 and 2 cases in each group respectively.Statistically significant differences were seen in early onset and refractory EMA among the three groups（both P<0.05）.In further two by two comparisons，the proportion of early onset and drug refractory cases was greater in children in group C than in group A，with statistically significant differences（both P<0.017），and the difference in concomitant MS among the three groups was not statistically significant（ P>0.05）. Conclusions:The MA seizures in children with EMA are sensitive to hyperventilation.The common accompanying seizure is MS.Some children with EMA present with early onset and refractory epilepsy，with a tendency towards developmental epileptic encephalopathy.

Objective: To determine the knowledge, attitudes and practices (KAP) regarding tuberculosis prevention and control among college students in Wuhan, China, while analyzing the factors affecting tuberculosis prevention behavior. Methods: Referring to the National KAP Questionnaire for Tuberculosis Prevention and Control among College Students, which was designed by China Center for Disease Control and Prevention, 22 colleges and universities in Wuhan were selected using a judgment sampling method, and a questionnaire survey was carried out through the online questionnaire platform. The formation of tuberculosis prevention and control behavior among this population was analyzed by single factor and multi factor Logistic regression. Results: The total awareness rate of KAP regarding tuberculosis prevention and control among college students in Wuhan was 79.69%; the awareness rate of core knowledge was 79.28%, and the passing rate was 92.46%. The correct attitude holding rate was 89.69%, while the passing rate was 90.56%. In respect to correct behavior, the formation rate was 72.11%, with a passing rate of 96.62%. The multivariate Logistic regression analysis showed that the following factors were more likely to promote tuberculosis prevention and control behaviors that met the target: female college students ( OR =1.86); college students whose father had a primary school education level, junior high school and equivalent, high school and equivalent, and junior high school students ( OR =2.94, 3.05, 3.17, 3.24 ); no history of tuberculosis ( OR =3.32); the passing knowledge of core knowledge ( OR =9.91), and the passing attitude holding score ( OR =7.35)( P <0.05). Conclusion The overall awareness rate of KAP regarding tuberculosis prevention and control among college students in Wuhan is acceptable,the mainly influenced factors are gender, history of tuberculosis, awareness rate of core knowledge about prevention and control, attitudes and cognition, and parents educational background.

ObjectiveTo investigate the infection of mouse norovirus (MNV) in experimental mice raised under natural conditions from 19 biological companies in Beijing. MethodsThe mice used in this study were randomly selected from mice produced by 19 companies, and 14 mice of each strain and batch were combined into one cage, totaling 1 396 cages of 19 544 mice. The fecal samples from BALB/c, C57BL/6, ICR, KM, and BALB/c-nude mice were collected. TaqMan probe fluorescence quantitative PCR method was used to detect MNV infection of mice with MNV-1 primer, and whether the mice were infected with MNV was determined according to cycle threshold (Ct value). The chi-square test was used to analyze the difference of positive rate among the fecal samples from the five types of mice. The Ct values of the positive samples were statistically described; the non-parametric test was used to analyze the differences in Ct values among the five types of mice. Results A total of 1 396 fecal samples were collected. The positive rates of fecal MNV detection in BALB/c, C57BL/6, ICR, KM, and BALB/c-nude mice were 17.65%, 39.33%, 10.57%, 18.32% and 27.4%, respectively. According to the chi-square test results, the positive rate of fecal in C57BL/6 mice was higher than that in BALB/c, ICR, and KM mice (all P<0.05), and the positive rate of BALB/c-nude mice was higher than that in ICR and BALB/c mice (P<0.001, P＜0.05) . The viral load of BALB/c-nude or C57BL/6 mice was generally greater than that of KM mice (P<0.05). ConclusionMNV-1 primers can be applied to the detection of MNV infection in mice. The positive rate of MNV in five types of experimental mice in Beijing ranges from 10% to 40%, among which C57BL/6 mice and BALB/c-nude mice have higher positive rates of MNV than the others.

Glucagonoma is a rare neuroendocrine tumor of α cells of the pancreas. The tumor excessively secretes glucagon and causes glucagonoma syndrome.70%-90% of patients with glucagonoma will develop necrolytic migratory erythema (NME). We reported a patient of glucagonoma syndrome who was presented to the dermatology outpatient clinic with a 2-year-history of recurrent erythema and scaling on the skin migrating throughout the body. A skin biopsy was performed and resulting features matched with NME, whilst imaging examinations suggested a soft tissue density tumor present in the tail of the pancreas with somatostatin receptor expression and laboratory tests found an elevated levels of serum glucagon. After the diagnosis was confirmed, the patient was treated with surgical resection of the glucagonoma and the skin eruptions resolved rapidly in 4 days. Meanwhile, we reviewed relevant literature published in recent years and summarized its clinical characteristics in order to improve its understanding by clinicians, including clinical manifestations, laboratory and imaging examinations, diagnosis and treatments.

Objective:To evaluate the effects of the cassette 14C-urea breath test kit, scintillation sampling bottle (solid-state scintillation method) and liquid scintillation 14C-urea breath test kit in the diagnosis of Helicobacter pylori ( H. pylori) infection. Methods:From January 7 to October 28, 2020, 239 patients were enrolled who visited Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, the Second Affiliated Hospital of Zhejiang University School of Medicine and the First Affiliated Hospital of Nanchang University. All subjects first received 14C-urea breath test.Within >1 to <7 days after gas collection, mucosal tissues were taken under gastroscopy for gold standard test, including biopsy and rapid urease test (RUT). If both biopsy and RUT indicated H. pylori positive, the result of gold standard test was H. pylori positive, and if both were negative, the result of gold standard test was H. pylori negative. If the results of biopsy and RUT were inconsistent, they were not included in the subsequent analysis. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were analyzed. The safety of the test was evaluated by whether there were any adverse events during the test. Descriptive methods were used for statistical analysis. Results:Among the 239 subjects, 12 cases did not complete the test, 227 subjects finally completed the test. The test completion rate was 95.0% (227/239). No.008 patient was only included in the analysis of cassette 14C-urea breath test kit and scintillation sampling bottle because of lacking the result of liquid scintillation breath test. The results of gold standard test showed that among 227 patients, 87 cases were H. pylori positive, 118 cases were H. pylori negative. The results of biopsy and RUT were inconsistent in 22 cases, so they were not included in the subsequent analysis. Excluding No.008 patient, the results of gold standard test showed that 86 cases were H. pylori positive and 118 cases were negative. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of cassette 14C-urea breath test kit, scintillation sampling bottle, and the liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were 91.9%, 100.0%, 96.6%, 100.0% and 94.4%, respectively; 95.4%, 97.5%, 96.6%, 96.5% and 96.6%, respectively; and 96.5%, 99.2%, 98.0%, 98.8% and 97.5%, respectively. Only one adverse event (right upper abdominal pain after eating) occurred. Combined with the patients condition, the adverse event was determined as the onset of chronic cholecystitis and it might not be related to the test medication. Conclusions:Cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit have reliable performance, good safety, and high sensitivity, specificity and accuracy in the diagnosis of H. pylori infection, which are worthy of clinical application.

Objective:To describe the baseline characteristics of the subjects enrolled in the China Quantitative CT (QCT) big data program in 2018—2019.Methods:Based on baseline data from the Chinese health big data project from January 2018 to December 2019 from the eligible enrolled population, measurements of bone mineral density (BMD) and visceral adipose tissue (VAT) were performed using Mindways′ QCT Pro Model 4 system. The baseline data of age, gender, regional distribution, height, weight, abdominal circumference, blood pressure, blood routine and blood biochemical tests were analyzed. And the single factor analysis of variance (ANOVA) was used to check the age related trend of BMD and VAT in both genders.Results:After screening the inclusion exclusion criteria and outliers of the main indicators, 86 113 people were enrolled in the project. The enrollment rate was 92.47%, including 35 431 (41.1%) women and 50 682 (58.9%) men, and the ratio of men to women was 1.43. The mean age was (50.3±12.7) years in all the subjects, and it was (50.2±12.8) years and (50.4±12.5) years in men and women, respectively, and there was no statistical difference between the two genders ( P>0.05). Total of 43 833 people were enrolled in east China, it was the largest group by region (50.90%), it was followed by central China (16 434 people, 19.08%), and the number of people enrolled in Northeast China was the lowest (2 914 people, 3.38%). The rate of completing of health information indicators related to the main outcome of the study were all above 70%, and there were significant differences between men and women (all P<0.05). The mean BMD was (139.33±46.76) mg/cm 3 in women, (135.90±36.48) mg/cm 3 in men, which showed a decreasing trend with age in both gender (both P<0.001); the mean intra-abdominal fat area was (116.39±56.23) cm 2 in women, (191.67±77.07) cm 2 in men, and there was an increasing trend with age in both men and women (both P<0.001). Conclusions:There are gender differences in BMD and VAT measured by QCT with different age tendency, and there are gender differences in health information index. Regional factors should also be taken into account for regional differences in the inclusion of data.

Objective:To investigate the normal reference values of spinal bone mineral density measured by quantitative computed tomography (QCT) and the differences of bone mineral density (BMD) in different regions of in Chinese adult males.Methods:Men who underwent low-dose CT lung scan for cancer screening in regions of Northeast, North, East, South, Central and Southwest of China from January 2018 to December 2019 were selected. And the lumbar vertebrae BMD values in the male subjects were measured by the QCT system (Mindways Software, Inc.). The mean BMD values and their decline rates were calculated at an age interval of 10 years, and the prevalence of osteoporosis was calculated according to the American College of Radiology spine QCT osteoporosis diagnostic criteria.Results:A total of 50 682 males with a mean age of (50.22±12.79) years (ranged 20 to 98 years) were included in this study. The peak BMD of (173.11±28.56) mg/cm 3 in the healthy Chinese adult male population appeared in the age group of 20 to 29 years and then declined with age. Before the age of 70 years, the BMD was relatively higher in males in South China, and it was lower in Central China and Southwest China, and it was intermediate in Northeast, North and East of China, with statistically significant differences. There was no significant differences in BMD in the males in the two age groups of 70 to 79 years and 80 and older among the regions in China. The overall decline rate of spinal BMD in Chinese males under QCT was about 46.92% over the lifetime, and it declined obviouslyin the 40-49 age group. The overall prevalence of osteoporosis in Chinese male population aged 50 years and above was approximately 11.42%, with the highest prevalence in Southwest China and Central China (14.72% and 13.87%, respectively) and the lowest in North China and South China (8.53% and 7.71%, respectively). Conclusions:A reference of lumbar spine BMD values for healthy males in China based on QCT is established. BMD values were highest in South China and Lowest in Central China.
