Objective Through the development of"real-time monitoring,early warning and tracking management sys-tem for infectious diseases in hospitals",real-time monitoring and early warning are realized,report cards are generated,and case tracking and management of infectious diseases are formed.Methods We selected 22 185 cases of infectious disease re-ports from April 2020 to October 2022 and 33 640 cases of infectious disease reports from November 2022 to May 2024,and com-pared the 19-month period before and after the launch of the new infectious disease early warning management system with that be-fore the launch of the original traditional infectious disease reporting management system,and compared the rate of infectious dis-ease reporting,the accuracy of infectious disease reporting,the timeliness of infectious disease reporting(time),the accuracy of infectious disease reporting,and the quality of infectious disease reporting(time),Infectious disease reporting timeliness(time),effectiveness of infectious disease tracking,and clinical medical staff's satisfaction with infectious disease reporting were compared and analyzed.Results After the use of the new hospital infectious disease early warning and tracking management sys-tem,the differences in infectious disease reporting rate,infectious disease reporting accuracy,infectious disease reporting timeli-ness,infectious disease tracking effectiveness,and clinical medical staff's satisfaction with infectious disease reporting were all sta-tistically significant(P＜0.05).Conclusion The development of"real-time monitoring,early warning and tracking management system for infectious diseases in hospitals"has significantly improved the reporting rate of infectious diseases,the accuracy of infec-tious disease reporting,the timeliness of infectious disease reporting,the effectiveness of infectious disease tracking,and the satis-faction of infectious disease reporting of clinical medical staff,and it has the characteristics of real-time,high efficiency and accura-cy,and the effect of early warning and tracking management is good,which has good value for promotion.It is characterized by re-al-time,high efficiency and accuracy,with good effect of early warning and tracking management,and has good promotion value.

Objective:To investigate and analyze case reporting ethical review and patient informed consent reports published in the comprehensive journals of clinical medicine in China in 2022.Methods:According to the data from the 2022 Edition of the Chinese Science and Technology Journal of the Citation Reports(Extended Version),the case reports published in comprehensive journals of clinical medicine in 2022 were selected as the research objects.The information on ethics and patient informed consent was extracted from the case reports that met the selection criteria,and Microsoft Excel 2021 and SPSS 21.0 were used to sort out and analyze the data.Results:A total of 587 case reporting articles were published in the 42 included journals in 2022,of which 36(6.13%)reported on science and technology ethics and/or informed consent.Case reports reporting on science and technology ethics and/or informed consent mostly came from the key magazine of China technology(88.89%Vs.65.88%),and the proportion of manuscripts involving science and technology ethics on the official website of the journal was relatively high(86.11%Vs.63.88%),and the difference was statistically significant(P＜0.01).Conclusion:The proportion of case reports of science and technology ethics and/or informed consent in journals of comprehensive discipline classification of clinical medicine was relatively low.Currently,most international journals are required to obtain the informed consent of patients or legal guardians before publishing case reports.Compared with this,there are still certain gaps in China,which need to be paid great attention to.

Objective:To investigate the teaching effect of flipped classroom combined with problem-based learning (PBL) in the teaching of the Diagnostic Audiology course.Methods:A total of 72 undergraduate students majoring in audiology and speech rehabilitation in the classes of 2019 and 2020 in Chongqing Medical University were enrolled as subjects, and three chapters of the Diagnostic Audiology course were selected for teaching reform. The 34 students in the class of 2019 were enrolled as control group and received lecture-based learning (LBL), and the 38 students in the class of 2020 were enrolled as experimental group and received flipped classroom combined with PBL. The teaching effect was evaluated by comparing the two groups in terms of classroom test scores, classroom participation scores, degree of satisfaction with teaching effect, and overall satisfaction with teaching. SPSS 23.0 software was used to perform the t-test, the chi-square test, and the Mann-Whitney U test. Results:The experimental group had a significantly higher classroom test score than the control group (25.95±1.21 vs. 23.21±1.55, P<0.001). In terms of classroom participation scores, the experimental group had significantly higher scores of participation in class discussion, cooperative and collaborative abilities, and questioning skills than the control group (all P<0.001). In terms of the degree of satisfaction with teaching, compared with the control group, the experimental group had significantly higher degrees of satisfaction in the dimensions such as interest in learning, mastery of theoretical knowledge, teamwork and collaboration abilities, self-learning ability, and self-presentation ( P=0.005, 0.009, 0.001, 0.016, and 0.005). In addition, the experimental group had a significantly higher degree of overall satisfaction with teaching than the control group ( P=0.006). Conclusion:Flipped classroom combined with PBL has a good teaching effect in the Diagnostic Audiology course and thus holds promise for further application.

Rheumatic diseases, a typical kind of autoimmune disease, are often treated with glucocorticoids, immunosuppressants, biological agents, and small-molecule targeted drugs, which often leads to immune dysfunction in patients and increases the risk of activation of latent tuberculosis infection. To regulate the screening, diagnosis, and prophylactic treatment of latent tuberculosis infection in patients with rheumatic diseases, reduce the risk of developing active tuberculosis and improve the prognosis, Peking University Shenzhen Hospital, Shenzhen Third People′s Hospital and Peking Union Medical College Hospital jointly organized domestic experts in the field of rheumatology and tuberculosis to establish the expert consensus on the diagnosis and treatment of latent tuberculosis infection in patients with rheumatic diseases. This consensus focuses on epidemiology, the importance of screening, screening methods, and prophylactic anti-tuberculosis treatment strategies for latent tuberculosis infection combined with rheumatic diseases.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Luohu District of Shenzhen has implemented the global budget management mode as " surplus reward, no compensation for overspending and reasonable sharing" in the hospital group, which continued to strengthen cooperation, optimize services, reduce costs, and improve health outcomes. The authors employed the game theory to build a game model of medical alliance under Luohu global budget management mode, discussing the reasons of medical and health institution′s stronger cooperation and what could be improved in Luohu′s case. Based on the experience of Luohu total budget management, it is suggested that when implementing total budget, all localities should improve closed-loop management, expand coverage, adopt compound medical insurance payment method, promote outpatient coordination, strengthen assessment and incentives, so as to give full play to the incentive role of total budget.

Germany has introduced the " point method" of fee-for-service at the outpatient departments under a global budget system, in an effort to curb medical expenditure growth. The authors employed the game theory to build a physician′s game model under Germany′s point method, illustrating the causes of " increasing points" behaviors of physicians, the negative effects caused by the increase of points as well as the prevention and control measures employed by Germany and its mechanism. Point method payment has been introduced in several areas in China at their inpatient departments, which is delivered to medical service providers via the performance-based distribution model, with the providers affected in their behaviors. As a result, some areas will tend to appear such " increasing points" behaviors as competing for patients, lowering admission criteria, and raising point value. In view of Germany′s experiences, China should adopt such measures as dynamic monitoring system, disclosure of " increasing points " behaviors, perfection of hierarchical medical system, and strengthening the self-governance via medical sector′s associations.

Objective:To analyze, with Wuhan as an example, the problems found in the infrastructure development of China′s healthcare institutions, and put forward optimization suggestions for future epidemic prevention and control.Methods:From May to June 2020, we surveyed with questionnaires 56 healthcare institutions in Wuhan, covering such aspects as basic information of the institutions, infectious disease infrastructure readiness, and the converted wards for COVID-19. Statistical descriptions were used to analyze data so acquired.Results:The number of beds in the infectious departments of healthcare institutions in Wuhan amounted to 1.64 per 10 000 people, yet the existing 1 873 beds and about 5 000 convertible beds failed to meet the medical needs against the outbreak of COVID-19. After the outbreak, a total of 19 084 convertible beds were set up, of which general hospitals accounted for 88%; the area occupied by each converted bed in traditional Chinese medicine hospitals, hospitals of traditional and Western medicine, and maternal and child hospitals (<30.0m 2) was lower than that in general hospitals and specialist hospitals (>40.0m 2). Conclusions:Healthcare institutions should scientifically allocate " peacetime-wartime adaptive" hospital beds, optimize both the number and efficiency of these beds, and prepare for the worst scenarios, so that the infrastructure can be built and maintained in strict accordance with standards, government departments can rationally arrange infectious disease prevention and control facilities and strengthen their planning in case of emergencies.

Objective To investigate the distribution characteristics and changing tendency of urinary tract stones.Methods From January 2011 to May 2017,clinical data of 15 269 patients treated in our center was retrospectively reviewed.The stone components were detected by the automatic stone infrared spectroscopy system and the predominant components were recorded.There were 9 019 male patients and 6 250 female patients.The patients were divided into four groups according to their age,including group A ≤ 18 years;group B 19-40 years;group C 41-60 years;and group D ＞ 60 years.Compared the distribution characteristics of urinary tract stones of patient in different groups of sex,age and calendar year.Results Calcium oxalate stones were more prevalent in males than females [6 221 (69.0％)vs.3 582 (57.3％),P ＜ 0.001],but calcium phosphate stones [210 (3.4％) vs.210 (2.3％)],magnesium ammonium phosphate stones [230(3.7％) vs.165 (1.8％)] and carbonate apatite stones [1 328 (21.3％) vs.1 030 (11.4％)] were more common in females than males (P ＜ 0.001,respectively).The proportion of uric acid stones in group D [679(20.7％)] was higher than that in group A [23(9.1％)],group B[260(7.9％)],group C [1 163 (13.8％)] (P ＜0.001,respectively).The peak of carbonate apatite stones was showed in group B [652(19.7％)] (P＜0.001,respectively).Ammonium urate stones [9(3.5％)] and cystine stones [36 (14.2％)] were more frequent in group A(P ＜0.001,respectively).In adults,the percentage of uric acid stones increased with age,such as group B [260(7.9％)],group C [1 163(13.8％)],group D [679 (20.7％)].And the carbonated apatite stones decreased with age,such as group B [652 (19.7％)],group C [1 270(15.1％)],group D [416(12.7％)] (P ＜0.001,respectively).Further analysis showed the proportion of calc ium oxalate (OR =0.944,95 ％ CI 0.927-0.962,P ＜ 0.001),ammonium urate stones (OR =0.854,95％ CI 0.742-0.982,P =0.027) decreased,while calcium phosphate (OR =1.192,95％ CI 1.127-1.261,P ＜0.001),uric acid (OR =1.042,95％ CI 1.015-1.069,P =0.002) and ammonium magnesium phosphate (OR =1.078,95％ CI 1.019-1.141,P =0.009) stones increased with time.Conclusions The distribution of stones was different in genders and age.Calcium oxalate stones were more common in male patients,while ammonium magnesium phosphate and carbonate apatite stones were more common in female patients.Uric acid stones were more frequent in patients older than 60,while carbonate apatite were more frequent in the 19-40 age group.The proportion of calcium oxalate and ammonium urate stones showed a downward trend,whereas calcium phosphate,uric acid and magnesium ammonium phosphate stones increased with time.

Objective: To investigate the proper time of intratympanic steroid as combination therapy in treatment of patients with profound sudden sensorineural hearing loss(SSNHL) of total frequency type. Methods: This prospective study included 50 patients with SSNHL in the First Affiliated Hospital of Chongqing Medical University from June 2017 to February 2018.All these patients had profound hearing loss averaged more than 81 dB at all frequencies (250-8 000 Hz). They were divided into two groups.The patients in group A were treated with simultaneous oral prednisone (1 mg/kg, qd) and intratympanic methylprednisolone (40 mg, qd) for 5 days.The patients in group B were treated with oral prednisone for 5 days as in group A, and then those who had no significant improvement were subsequently treated with intratympanic methylprednisolone (40 mg, qd)for further 5 days.All patients were treated with additional intravenous batroxobin and ginkgo biloba leaves extract.Following examination of pure tone audiogram, hearing gains and effective rates were statistically analyzed in both groups with SPSS software package(version 20.0). Results: Hearings in both groups were improved significantly after treatment.In group A(20 cases), hearing gain was (29.2±22.7) dB and total effective rate was 65.0%, while in group B(22 cases), they were (27.3±22) dB and 68.2% respectively.There were no significant differences in hearing gain and recovery rate between two groups (hearing gain, P=0.793; total effective rate, P=0.827). Conclusions For patients with profound SSNHL of total frequency type, the efficacies of intratympanic steroid as simultaneous and subsequent therapy are equivalent. Therefore, subsequent intratympanic glucocorticoid is recommended for SSNHL patient of total frequency type to reduce complications and medical expenses.
