Chronic heart failure （CHF） is a major global public health problem， and myocardial infarction is one of its main causes. The mouse model of heart failure induced by coronary artery ligation is widely used in the study of CHF， while the TCM syndrome attributes of this model have not yet been clarified. According to the theory of correspondence between prescriptions and syndromes， the method of syndrome identification by prescription efficacy is an important means of current syndrome research of animal models. This method deduces the syndrome characteristics of animal models through prescription efficacy. Taking the four basic syndrome elements of Qi， blood， Yin and Yang as the classification reference， this study used coronary artery ligation to construct a mouse model of CHF and treated the model with four representative TCM injections with the effects of replenishing Qi， warming Yang， nourishing Yin， and activating blood and enalapril. Echocardiography， tongue color parameters， histopathology， serum N-terminal pro-brain natriuretic peptide （NT-proBNP） and cardiac troponin Ⅰ （cTnⅠ） levels， and systematically explored the TCM syndrome attributes of this model. The results showed that the coronary ligation model presented an obvious cardiac function decline， myocardial fibrosis， infarct size expansion， and purple dark tongue， which were consistent with the basic syndrome characteristics of blood stasis in CHF. Danhong injection had significant effects of improving the cardiac function， alleviating myocardial fibrosis， and reducing serum NT-proBNP and cTnⅠ levels. Huangqi Injection and Shenfu injection can improve the cardiac function and tongue color parameters， with limited effects. The effect of Shenmai injection group was not obvious. This study verifies that the established model conforms to blood stasis syndrome through the method of syndrome identification by prescription efficacy， which provides an experimental basis for the study of TCM syndrome mechanism of CHF.

Chronic heart failure is the terminal stage of various cardiovascular diseases， and cardiomyocyte apoptosis is the turning point of decompensation. Studies have shown that traditional Chinese medicine （TCM） could regulate apoptosis-related signaling pathways and factors and inhibit or up-regulate the expression of apoptosis-related proteins. Thus， TCM can reduce cardiomyocyte apoptosis， protect the myocardial tissue and improve the cardiac function， demonstrating remarkable clinical effects. In recent years， the research on the treatment of chronic heart failure based on the inhibition of cardiomyocyte apoptosis is increasing and becomes the current research hotspot. On the basis of literature review， this paper discovers that TCM regulates apoptosis factors and multiple signaling pathways to inhibit apoptosis and inflammation and delay the progression of chronic heart failure through classical pathways such as the death receptor pathway， the mitochondrial pathway， and the endoplasmic reticulum pathway. At the same time， the studies in this field have the following problems： Repeated studies with shallow， simple， and fragmented contents， treating animal models with TCM prescriptions without syndrome differentiation， treating diseases with drugs at only one concentration which is insufficient to indicate efficacy， and lacking comprehensive， holistic， and systematic studies on the relationships of apoptosis with inflammatory responses， pyroptosis， ferroptosis， and autophagy. In the future， more scientific， reasonable， comprehensive， and feasible experimental schemes should be designed on the basis of comprehensively mastering the research progress in this field， and the communication and cooperation between researchers in different disciplines should be strengthened. The specific pathological mechanism of cardiomyocyte apoptosis in chronic heart failure and the signaling pathways， active components， and action targets of TCM in inhibiting cardiomyocyte apoptosis in chronic heart failure should be elucidated. Such efforts are expected to provide sufficient reference for the clinical treatment of chronic heart failure.

OBJECTIVE: To analyze the clinical characteristics of a patient with Short rib-polydactyly syndrome type 6 (SRTD6) with long-term misdiagnosis, and improve its clinical recognition by reviewing the relevant literature. METHODS: A patient presented at the Children's Hospital Affiliated to Zhejiang University School of Medicine on August 19, 2024 for the discovery of liver dysfunction for 13 years and vision loss for 9 years was selected as the study subject. Her medical history, clinical data, laboratory findings and results of imaging examination were collected. High-throughput sequencing was carried out, and candidate variants were verified by Sanger sequencing. This study was approved by the Ethics Committee of the Hospital (Ethics No.: 2021-IRB-292). RESULTS: The patient had long-term unexplained liver dysfunction, vision loss, and growth delay. Blood acylcarnitine and urinary organic acid analysis have failed to found any abnormality. Previous genetic testing revealed a homozygous c.203A>C (p.Glu68Ala) missense variant in the ETFDH gene, leading to a misdiagnosis of various acyl-CoA dehydrogenase deficiencies. However, treatment with high-dose vitamin B₂ showed a poor effect. Physical examination revealed small hands, short and stubby fingers, and a narrow chest. Medical imaging showed shortened bilateral ribs, a narrowed chest, and short, thick metacarpals. High-throughput sequencing has detected a pathogenic homozygous c.1957C>T (p.R653*) nonsense variant in the NEK1 gene, confirming the diagnosis of SRTD6. CONCLUSION SRTD6 is characterized by rib and sternum dysplasia as the primary skeletal deformities, which is often accompanied by multi-organ impairment. Genetic testing can facilitate the precise diagnosis.

Objective:To investigate the current situation and correlation between mental health and stressors of new professional master's degree graduates in clinical medicine, and to provide empirical support for improving student mental health.Methods:An online questionnaire survey was conducted among 3 587 fresh graduate students with master's degree in clinical medicine from 65 training institutions in China. SPSS 26.0 was used to compare and analyze the measurement data. Descriptive statistics were used to analyze the mental health using Symptom Checklist-90 (SCL-90) and the current status of stressors. The influence factors and correlation between mental health and stressors were analyzed by means of differentiation analysis and correlation analysis.Results:The SCL-90 overall mean score as well as the scores of obsessive-compulsive symptoms, interpersonal sensitivity, depression, terror, anxious, psychoticism, and hostility of new professional master's degree graduates in clinical medicine were all higher than the national norm ( P<0.05). Among the participants, 58.21% (2 088/3 587) exhibited varying degrees of symptoms listed in the SCL-90. Students from families with low per capita income and low parental education level have more prominent psychological problems. The top three stressors perceived were job seeking, research tasks, and self-ability. Students with positive SCL-90 symptoms reported significantly higher perceived stress in all three stressor dimensions compared to their symptom-negative counterparts ( P<0.001), indicating a significant correlation between mental health status and stressors. Conclusions:The mental health status of new professional master's degree graduates in clinical medicine is concerning and warrants focused attention from educational authorities, academic institutions, and families.

Objective:To understand the graduation destination of newly graduated medical master's students in China and analyze their employment status.Methods:A questionnaire survey was conducted on 15 942 medical master's students who graduated in 2023. Descriptive analysis, χ2 test, and Kruskal-Wallis rank-sum test were used to understand the current situation and differences in the graduation destinations, employment units, job positions, and starting salaries of different types of medical master's graduates. Results:The employment rate of medical master's graduates was 58.21% (9 280/15 942). In terms of graduation destinations, male graduates, professional degree holders, graduates from non-"Double First-Class" universities, and nursing majors had a high proportion of confirmed employment units. Male graduates, academic degree holders, graduates from "Double First-Class" universities, and basic medical science majors had a high proportion pursuing further studies domestically. In terms of employment, the highest proportion of medical master's graduates worked in hospitals (84.92%, 6 495/7 648) and the lowest proportion worked in primary-level medical and healthcare institutions (1.02%, 78/7 648). The majority (78.07%, 5 971/7 648) held professional technical positions. Starting salaries were relatively low and ranged between 3 001 and 5 000 yuan/month, accounting for 30.99% (2 370/7 648).Conclusions:The employment rate of medical master's graduates is low, with concentrated employment units and job positions, and there is a lack of talents in primary medical institutions. Colleges and universities and education management departments should adopt policy-driven approaches to support key demographic groups and encourage employment in primary healthcare. Training programs should be timely adjusted in response to market demands and focus on cultivating the comprehensive quality and job competence of medical master's graduates. Additionally, student-centered approaches should be used to strengthen the employment guidance and career planning services.

Objective:To investigate the short-term efficacy of robotic versus laparoscopic-assisted right hemicolectomy.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 99 patients of right colon cancer who were admitted to Tianjin Medical University General Hospital from January 2020 to December 2023 were collected. There were 50 males and 49 females, aged 69(range, 26?89)years. Of the 99 patients, 41 patients undergoing robotic-assisted right hemicolectomy were divided into the robotic group, and 58 patients undergoing laparoscopic-assisted right hemicolectomy were divided into the lapa-roscopic group. Patients received robotic-assisted or laparoscopic-assisted right hemicolectomy operated by the same major surgeon. Observation indicators:(1) propensity score matching status and com-parison of clinical data of patients between the two groups after matching; (2) intraoperative and postoperative conditions.Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the nonparametic rank sum test. Propensity score matching was performed using the 1∶1 nearest neighbor matching method. The caliper value was set as 0.1. Results:(1) Propensity score matching status and comparison of clinical data of patients between the two groups after matching. Of the 99 patients, 82 patients were successfully matched, with 41 cases in each of the robotic group and the laparoscopic group. After propensity score matching, the elimination of history of abdominal operation confounding bias ensured comparability. (2) Intraoperative and postoperative conditions. After propensity score matching, the operation time of the robotic group was 215(range, 130?340)minutes, the volume of intraoperative blood loss was 50(range, 10?400)mL, the number of lymph node dissected was 21(range, 5?55), the number of intensive care unit stay was 15, time to postoperative first flatus was 3(range, 1?12)days, time to postoperative first food intake was 4(range, 2?14)days, duration of postoperative hospital stay was 8(range, 5?25)days. The above indicators of the laparoscopic group were 210(range, 140?370)minutes, 50(range, 5?150)mL, 19(range, 5?34),20, 3(range, 0?9)days, 5(range, 2?10)days, 8(range, 6?17)days, respectively. There was no significant difference in the above indicators between patients of the two groups ( Z=?0.94, ?1.87, ?1.32, χ2=1.25, Z=0.13, ?0.83, ?0.65, P>0.05). There was no patient converted to open operation in the robotic group, versus 1 patient converted to open operation in the laparoscopic group, showing no significant difference between patients of the two groups ( P>0.05). There were 6 cases in the robotic group and 4 cases in the laparoscopic group with complications, showing no significant difference between the two groups ( χ2=0.46, P>0.05). Both groups of patients achieved R 0 resection and had no readmission 30 days after surgery. The hospital expense was (11.0±1.8)×10 4 yuan of the robotic group, versus (9.0±1.7)×10 4 yuan of the laparoscopic group, showing a significant difference between the two groups ( t=?5.27, P<0.05). Conclusion:Robot-assisted right hemicolectomy is non inferior to laparoscopic-assisted right hemicolectomy in safety and efficacy, but with higher hospitalization costs.

Objective : To analyze the epidemiological characteristics of tuberculosis in Urumqi and assess the im⁃pact of the national health examination policy , as well as COVID⁃19 prevention and control measures , on tuberculo⁃sis incidence in Xinjiang. Methods: The seasonal patterns of pulmonary tuberculosis were examined using the seasonal index method and circular distribution analysis. An Interrupted Time Series (ITS , Interrupted Time Series) model was employed to investigate how the national health examination policy and COVID_19 interventions influenced trends in tuberculosis incidence in Urumqi. Results: From 2013 to 2021 , a total of 19 ,049 cases of tuberculosis were reported in Urumqi. The peak incidence day occurred on May 25th , indicating a consistently high rate throughout the year, particularly during spring and summer months. The results of the interrupted time series model indicated that the initial monthly incidence rate of pulmonary tuberculosis in Urumqi was 5. 05 per 100 ,000. From January 2013 to September 2016 , the incidence rate of pulmonary tuberculosis showed a slow upward trend , and the upward trend was significant (β1 = 0. 039 ,P < 0. 05) . After the implementation of the universal health checkup policy , the incidence rate of pulmonary tuberculosis showed a slow downward trend , and the downward trend was significant(β3 = - 0. 109 ,P < 0. 05) . After the outbreak of the COVID_19 epidemic in January 2020 , the incidence rate of pulmonary tuberculosis in Urumqi first dropped rapidly and then entered a slow upward stage , and the upward trend was significant(β5 = 0. 082 , P < 0. 05) . Conclusion It is recommended that public health authorities prioritize timely identification of potential TB patients during periods with elevated incidence rates observed in spring and summer months. While significant progress has been made through implementing national health examinations policies , attention must be directed towards understanding how ongoing epidemics affect TB patient detection. Thus , enhancing surveillance efforts and intervention strategies are essential in adapting to this new normal.

Objective:To evaluate the clinical performance of high-risk human papillomavirus (HR-HPV) genotyping in cervical cancer screening.Methods:Between June and July 2017, a prospective cervical cancer screening cohort was established in Xiaye Town, Jiyuan City, Henan Province, China by recruiting 3 254 women aged 21 to 64 years. At baseline screening, cervical exfoliated cell specimens were collected for HR-HPV genotyping and liquid-based cytology testing. Follow-ups were conducted over a 3-year period, with cytology testing in the first and second years and both HR-HPV genotyping and cytology testing in the third year. Women meeting the referral criteria were referred for colposcopy, with cervical biopsy and histopathological diagnosis performed as necessary. The endpoint was defined as cervical intraepithelial neoplasia grade 2 (CIN2) or higher confirmed by histopathological diagnosis. The sensitivity and specificity for detecting CIN2 or higher lesions of HR-HPV genotyping were calculated, as well as the cumulative risk of developing CIN2 or higher lesions over the 4-year study period in women with different baseline HR-HPV genotyping results.Results:A total of 2 741 women were included in the statistical analysis. Baseline HR-HPV genotyping detected 453 HR-HPV positive cases (16.53%), including 98 HPV 16/18 positive cases (3.58%) and 355 other HR-HPV positive cases (12.95%). During the 4-year period, 83 cases of CIN2 or higher were diagnosed. The sensitivity and specificity of baseline HR-HPV positivity for CIN2 or higher were 89.16% (95% CI: 80.66%-94.19%) and 85.74% (95% CI: 84.36%-87.02%), respectively. The corresponding rates for HPV 16/18 positivity were 43.37% (95% CI: 33.24%-54.09%) and 97.67% (95% CI: 97.02%-98.18%). The 4-year cumulative absolute risk of CIN2 or higher was highest in the HPV 16/18 positive group (36.73%, 95% CI: 27.85%-46.62%), followed by other HR-HPV positive groups (10.70%, 95% CI: 7.87%-14.38%), and the HR-HPV negative group was the lowest (0.39%, 95% CI: 0.19%-0.76%). Conclusions:HR-HPV genotyping testing exhibits high sensitivity and specificity for detecting CIN2 or higher lesions in cervical cancer screening. It also provides a scientific basis for stratifying the individual risk of developing CIN2 or higher lesions to guide subsequent management. Therefore, the HR-HPV genotyping testing can be considered as an effective method for cervical cancer screening.
