Based on the theory of "shaoyang（少阳） resembling the pivot" and collateral diseases， this article proposes that pulmonary fibrosis （PF） can be divided into three stages including wind bi （痹）， constraint bi， and atrophy bi. The core pathogenesis of PF is the obstruction of the pivot and pulmonary collateral obstruction. In terms of treatment， the basic principles are to harmonize and regulate the pivot， and to promote the circulation of the lung collaterals. Depending on the different characteristics of the "essence-attribute-function"， treatment methods such as harmonizing and regulating the pivot， resolving phlegm and removing stasis， supplementing deficiency and harmonizing collaterals are suggested. This approach ensures the regulation of the pivot， smooth circulation of qi and blood， unblocking of the lung collaterals and nourishing the lung body， achieving the goals of balancing the ascending and descending of qi， removing phlegm and stasis， and relieving cough and wheezing.

Objective To evaluate the application of flipped classroom(FC)approach in endocrine system integrated course for students from 4+4 clinical medicine pilot class at Peking Union Medical College(PUMC).Methods The study included the students of 4+4 clinical medicine pilot class grades 2019-2023 in PUMC.The students of grades 2019-2021(n=77)served as the control receiving traditional teaching method,while the students of grades 2022 and 2023(n=76)were selected as the experimental group,which were taught by FC approach.The selected teaching content is thyroid theme.The scoring rates of thyroid related questions in the final exam were as-sessed and a questionnaire survey was conducted to evaluate teaching satisfaction and effectiveness.Results The scoring rates of experimental group were significantly higher as compared to that of control group(P＜0.05).Over 90％of the students in the experimental group strongly satisfied or satisfied with the teaching content arrangement,design form,classroom atmosphere,teacher-student interaction of FC and expressed willingness to continue with this methodology.In addition,over 90％of the students strongly agreed or agreed that FC stimulated learning inter-est,improved self-learning ability,strengthened the connection between theory and clinical practice,inspired clini-cal reasoning,enhanced the abilities to analyze and solve problems,and cultivated communication and teamwork skills.Conclusions The application of FC approach in endocrine system integrated course achieved excellent teaching outcomes with high satisfaction of the students.

ObjectiveTo investigate the current status of emergency management for severe mental disorders in Shanghai, and to provide countermeasures and suggestions for the establishment of a sound emergency management system for severe mental disorders and the enhancement of emergency management capability. MethodsA questionnaire survey and qualitative interviews were used to conduct an investigation into the emergency management in 17 district-level mental illness prevention and control institutions in Shanghai, which includes the basic situation of emergency management for severe mental disorders, the construction of emergency response teams and personnel, emergency preparedness drills and training, emergency management plans and rules and regulations, and problems encountered in emergency management. ResultsIn terms of emergency management mechanism and basic situation, resources such as personnel allocation, security funds and green channel were well equipped in each district-level mental illness prevention and control institution in Shanghai. However, the equipment of some hardware facilities was still insufficient to some extent. Therefore, further improvement on the emergency management mechanism for severe mental disorders was needed. With regard to the construction of emergency team and personnel allocation, the majority were those aged between 35‒<45 years old, with a bachelor’s degree, and more than 10 years of working experience. For example, 90.27% staff in district-level mental illness prevention and control institution had a bachelor’s degree or above, which was higher than that among the staff in community-level (73.60%); staff majored in clinical medicine in district-level institution accounted for the proportion at 52.71%, higher than that among the staff in community-level (28.86%); 57.24% staff in district-level institution had an intermediate professional title, higher than that among the staff in community-level (42.28%); and 69.90% staff in district-level institution had more than 10 years of working experience, higher than that among the staff in community-level (43.62%). In the aspect of emergency drills and training, all district-level mental illness prevention and control institutions in Shanghai had a high demand for emergency training, and the weak aspects mainly focused on lack of emergency service protocols, skills of addressing technical challenges, and construction of effectiveness evaluation system. Moreover, the teaching methods were primarily centered on case analysis, simulation drills, interactive discussions, and so forth. Concerning emergency management plans and rules and regulations, all districts in Shanghai had relatively established well-developed systems for emergency response plans, emergency response leadership groups, and emergency response operational task forces for severe mental disorders. About half of the institutions had established other rules and regulations related to emergency management of severe mental disorders in addition to emergency plans. ConclusionShanghai has initially established an emergency management system for severe mental disorders, but it is still fragile in specialized training for emergency management of severe mental disorders, construction of emergency management mechanisms, and the building-up of grassroots emergency teams. Further priorities should include strengthening emergency management training, enhancing the construction of emergency management personnel teams, and gradually establishing a more comprehensive and integrated emergency management mechanism for severe mental disorders.

OBJECTIVE: To explore the current status, evolution, hot topics, and future research trends in the field of burn-related sepsis research through a visual analysis of literature. METHODS: A bibliometric method was employed to retrieve articles related to burn-related sepsis from January 1, 1994, to May 16, 2024, in the China National Knowledge Infrastructure (CNKI) and the Web of Science database. The CiteSpace 6.3.R1 software was used to analyze the retrieved literature. The number of publications, authors, countries, and institutions in both Chinese and English literature was statistically analyzed. Co-occurrence analysis, clustering analysis, and co-citation analysis of keywords were performed. RESULTS: A total of 1 090 articles from the CNKI database and 1 143 articles from the Web of Science database were retrieved. Over the past 20 years, the volume of Chinese publications has remained stable, although there has been a slight decline in the past two years. In contrast, the number of English publications, after a period of growth, showed a sharp decline over the past three years. In Chinese literature, 1 457 authors published articles on burn-related sepsis as first authors, with 14 core authors publishing four or more articles. In English literature, 98 authors published articles on burn-related sepsis as first authors. Research on burn-related sepsis was conducted by 76 countries, with the United States having the most collaborations and publications. Globally, 1 349 institutions published articles on burn-related sepsis, with the top institutions being the First Affiliated Hospital of the PLA General Hospital (8 articles) for Chinese literature and the University of Texas Medical Branch (57 articles) for English literature. In the co-occurrence analysis, 208 Chinese keywords and 211 English keywords were included. Excluding keywords related to search terms, the top five most frequent keywords in Chinese literature were burn, sepsis, infection, severe burn, and procalcitonin; the top five most frequent keywords in English literature were sepsis, septic shock, mortality, injury, and burn injury. Chinese keyword analysis identified six clusters, with the largest being sepsis, followed by procalcitonin, infection, and severe burn. English keyword analysis identified seven clusters, with the largest being expression, followed by epidemiology, inhalation injury, and acute kidney injury. The persistent clusters in Chinese literature were procalcitonin, with recent emerging nodes being severe burn, inflammatory response, platelets, and predictive value. In English literature, the persistent clusters were inhalation injury and nitric oxide, with recent emerging nodes being continuous renal replacement therapy, hemorrhagic shock, and early enteral nutrition. The longest-lasting emergent keyword in Chinese literature was delayed resuscitation (2003-2010), with the highest emergent strength being severe burn. In English literature, the longest-lasting emergent keywords, each lasting five years, were nitric oxide (2007-2012), management (2019-2024), and impact (2019-2024), with the highest emergent strength being thermal injury. CONCLUSIONS Research on burn-related sepsis has shifted from focusing on early studies on pathogenesis and mortality to focus on prevention, treatment, and early diagnosis. Future research is expected to focus on early diagnosis and risk factors of burn-related sepsis.

ObjectiveTo investigate the prevalence of cardiovascular diseases and their influencing factors in community-based schizophrenia patients in Shanghai, and to provide a scientific basis for the early identification and prevention of cardiovascular disease in this population. MethodsBased on the Shanghai community cohort with severe mental disorders in 2022, a total of 3 954 community-based schizophrenia patients were identified and included in this study through a stratified cluster sampling method. Basic information and relevant clinical data (including metabolic index data) were collected through questionnaire survey, physical examination and laboratory testing. Univariate analyses were performed using the chi-square tests, and multivariate logistic regression analyses were employed to identify influencing factors of comorbid cardiovascular diseases. ResultsA total of 3 954 community-based schizophrenia patients were included, of which a total of 1 237 (31.28%) patients had comorbid cardiovascular diseases. Multivariate logistic regression analyses showed that age 60 years old or above (OR=5.524, 95%CI: 3.716‒8.214), smoking behavior (OR=1.328, 95%CI: 1.042‒1.692), overweight (OR=1.900, 95%CI: 1.046‒3.451) or obesity (OR=2.678, 95%CI: 1.439‒4.985), elevated blood pressure (OR=1.546, 95%CI: 1.294‒1.846), abnormal fasting blood glucose (OR=1.552, 95%CI: 1.322‒1.823) and high-density lipoprotein cholesterol abnormalities (OR=1.283, 95%CI: 1.025‒1.606) were positively associated with the risk of comorbid cardiovascular diseases in patients with schizophrenia, while educational attainment of college/bachelor’s degree or above (OR=0.640, 95%CI: 0.450‒0.910) and being unmarried (OR=0.552, 95%CI: 0.457‒0.667) were negatively associated with the risk of cardiovascular diseases comorbidity. ConclusionAdvanced age, unhealthy behaviors and lifestyles, as well as abnormalities in blood pressure, blood glucose, and blood lipids, could all increase the risk of comorbid cardiovascular diseases in community schizophrenia patients. It is suggested to strengthen the monitoring and management of these risk factors in this population in the future, so as to achieve early detection, early diagnosis and early intervention of cardiovascular diseases.

Objective To investigate the correlation between the expression of integrin α 2(ITGA2)and recurrence risk of papillary thyroid microcarcinoma(PTMC).Methods PTMC and para-carcinoma tissue were collected from patients who underwent surgery and pathologically confirmed at the hospital from Decem-ber 2022 to June 2023,and the expression of ITGA2 in PTMC and paracarcinoma tissue were observed using immunohistochemistry method.Clinical characteristics of all patients were collected and the differences in clin-icopathological characteristics between patients in ITGA2-positive and-negative groups were compared.Ac-cording to the risk stratification criteria for tumor recurrence,the differences in ITGA2 expression between groups were compared.Results The expression level of ITGA2 in PTMC was higher than that in para-carci-noma tissues,and the difference was statistically significant(P＜0.001).Multivariate logistic regression anal-ysis showed that BRAF mutation(OR=2.668)and larger total tumor diameter(TTD,OR=1.111)were risk factors for ITGA2 overexpression(P＜0.05).ITGA2 positive expression was associated with the risk of tumor recurrence(P=0.009).Conclusion ITGA2 can be used as a novel molecular biomarker for clinical ap-plication.

Objective To investigate the needs and feedback from clinical medical students on the diversified teaching mode adopted by the Department of Endocrinology in Peking Union Medical College Hospital.Methods Questionnaires were distributed to the medicine students who were in clinical rotation in Peking Union Medical Col-lege,and the teaching status and teaching effect was investigated.Results A total of 95 valid questionnaires were received.The attending physicians and the teaching resident physicians performed well in the daily teaching activi-ties.The medical students believed that outpatient training was necessary in addition to ward rotations.After the ro-tation in the endocrinology department,the self-evaluated score of mastery of endocrinology knowledge had been significantly improved,especially in those who rotated in outpatient clinic,suggesting that outpatient teaching was of great significance.In addition,the establishment of a self-learning platform including clinical cases and videos in endocrinology could be used as an important supplementary means for clinical teaching.Conclusions Outpatient training improves learning outcomes of medical students,so must be kept and further strengthened in the future.Building a database of typical clinical cases and teaching videos can improve the training quality.

Objective:To analyze the clinical characteristics of invasive klebsiella pneumoniae liver abscess syndrome (IKPLAS), and compare it with common pyogenic liver abscess (CPLA). Methods:The social demography and clinical data of inpatients with pyogenic liver abscess from January 2011 to December 2021 in the Peking University People's Hospital were collected. Based on the presence or absence of invasive infections and the results of bacterial etiology, IKPLAS was diagnosed and compared with CPLA. The general information, symptoms, past medical history, auxiliary examinations and prognosis indicators of the two groups of patients were compared.Results:Total of 172 patients with pyogenic liver abscess were collected, including 25 cases of IKPLAS. Compared with CPLA group, the proportion of fever in IKPLAS group was lower, the proportion of diabetes history was higher, the proportion of monocytes was lower, and procalcitonin and urea nitrogen were higher(all P<0.05), the proportion of multiple abscesses is higher, and the positive rate of blood culture and the cultivation of klebsiella pneumoniae are both higher (all P<0.05).A total of 9 cases (5.2%) of patients developed septic shock, of which 2 cases (1.2%) died. The IKPLAS group had a higher proportion of ICU admissions ( P<0.05),but but the difference of mortality between the two groups was not statistically significant ( P>0.05). The most common sites of invasion infection in the IKPLAS group are the lungs(22/25), brain(9/25), and eyes(9/25). Conclusions:There are differences in clinical characteristics between IKPLAS and CPLA, the most common sites of invasion infection are the lungs, brain, and eyes, but there is no difference in mortality in this study. For PLA with pathogenic Klebsiella pneumoniae, it is necessary to carefully evaluate the presence of invasive lesions and provide targeted local treatment to better improve prognosis.

Objective:To explore the association between postoperative radiotherapy for bladder cancer and the risk of second primary rectal cancer.Methods:Eligible 75 120 patients with bladder cancer from the Surveillance, Epidemiology, and End Result database (SEER) of the National Cancer Institute (NCI) (1975-2017) were enrolled in this study. The second primary cancers referred to rectal cancers patients suffered after more than five years post-treatment for bladder cancer, and the cumulative incidence was estimated using Fine-Gray competing risk regression. The relative risk (RR) of rectal cancer in patients treated with or without radiotherapy (the RT group or the NRT group) was evaluated using Poisson regression.Results:Among the 75 120 patients, 70 045 (92.4%) were Caucasian, with a median age of 65.8 years (54-74 years). A total of 2 236 (3%) received postoperative radiotherapy, while 72 884 (97%) received surgery alone. The 30-year follow-up revealed a cumulative incidence of rectal cancer of 0.93% in the RT group and 0.43% in the NRT group ( P = 0.004). The competing risk regression analysis identified a significant association between radiotherapy and rectal cancer ( HR: 1.86; 95% CI 1.26-2.74, P < 0.009). Furthermore, the RR of radiotherapy-associated rectal cancer significantly increased as the diagnosis occurred earlier (1975-1985 vs. 1985-1994: RR 2.59; 95% CI 1.20-4.86, P < 0.001), and a lower age at the time of radiotherapy was associated with a higher probability of second primary tumors (≤50-year old vs. > 50 year old : RR 7.89, 95% CI 2.97-21.30, P < 0.001). As calculated using the Poisson distribution, the RR of second rectal tumors was higher in the RT group ( RR: 2.20, 95% CI 1.45-3.18, P < 0.001), even after adjusting the date of diagnosis ( RR: 1.77, 95% CI 1.17-2.57, P = 0.009). Conclusions:An increased risk of rectal cancer following bladder cancer radiotherapy necessitates aggressive follow-ups for the purpose of early detecting second primary rectal cancer associated with bladder cancer radiotherapy.

ObjectiveTo analyze the temporal distribution characteristics of crisis calls and eight major counseling issues to the Shanghai mental health hotline, and to provide recommendations for improving hotline management. MethodsDescriptive statistics were used to analyze 1 106 crisis calls and the calls of eight major counseling issues to the Shanghai mental health hotline across months, time periods and weeks from October 2021 to September 2023, and the chi-square test was used to analyze whether there was any difference in the distribution of 1 106 crisis calls and the calls of eight major counseling issues across months, time periods and weeks. ResultsThere were significant differences in the number of crises calls across different months (χ²=87.816, P<0.05), time periods (χ²=161.848, P<0.05), and weekly distributions (χ²=63.329, P<0.05). The highest number of calls occurred in September, while January had the lowest. The peak call times were between 18:00‒20:00, with the fewest calls occurring between 3:00‒5:00. The day of the week with the highest number of calls was Saturday, while Wednesday had the lowest. Among the different types of counselling issues in crisis calls, the highest number of calls were related to mental disorders, while the fewest calls were related to COVID-19. ConclusionCrisis calls to the Shanghai mental health hotline are concentrated at specific times, indicating that relevant organizations should optimize resource allocation based on this time distribution.
