As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

ObjectiveTo analyze the epidemiological and clinical characteristics of the 21 confirmed monkeypox cases in a district of Chengdu City, and to provide scientific guidance for the prevention and control of subsequent monkeypox epidemics. MethodsData of confirmed monkeypox cases residing in this district were collected from the Disease Control and Prevention Information System of China. A retrospective descriptive epidemiological analysis was used to analyze the demographic, distributional and behavioral characteristics of the cases. ResultsThe first confirmed case of monkeypox was reported on July 5, 2023. Up to April 30, 2025, a total of 21 confirmed cases of monkeypox have been reported. All cases were male, with a mean age of (30.9±6.2) years. The highest proportion of cases(47.62%) was in the 30‒40 years age group. The majority were men who have sex with men (MSM) population (90.48%, 19/21). The results showed that 19.05% of cases were co-infected with HIV, and 19.05% had a history of syphilis infection. Within 21 days prior to symptom onset, 19 cases (90.48%) self-reported engaging in male-to-male sexual contact, among whom 10 cases (52.63%) reported having taken protective measures, while 9 cases (47.37%) did not take safety precautions. Thirteen cases (61.90%) had no travel history to areas with reported monkeypox cases during the 21 days before symptom onset. The predominant manifestation was exanthem (100%, 21/21), followed by fever (57.14%, 12/21) and lymphadenectasis (47.62%, 10/21). Among febrile cases, 50.00% (6/12) had low-grade fever (37.3‒38.0 ℃). All cases were identified through active medical consultation. The median interval from symptom onset to the first medical visit was 3 (2, 6) days, with a maximum interval of 14 days. The median interval from symptom onset to laboratory confirmation was 7 (5, 9) days. Six cases (28.57%) had two or more visits to the hospital, with bacterial infection being the primary initial diagnosis. ConclusionMonkeypox prevention and control efforts in a district of Chengdu City should prioritize MSM population and young and middle-aged adults aged 30 to <40 years. It is recommended to establish an integrated monkeypox epidemic prevention and control network by leveraging existing HIV/AIDS prevention and control network. Concurrently, accelerating the deployment of the national intelligent infectious disease monitoring and early warning front-end software will strengthen early detection capabilities and be beneficial for the overall effectiveness of epidemic prevention and control efforts.

The Department of Thoracic Surgery of Shanghai Chest Hospital has performed esophageal function testing for over 30 years, being the only department of its kind in China with this capability. The pressure testing and 24-hour pH/impedance monitoring of the esophagus is of great help to assist in the diagnosis and treatment of benign and malignant esophageal diseases related to it. Thanks to the esophageal function test, in addition to the routine various endoscopic anti-reflux procedures, our hospital has taken the lead in China in recent years to carry out a series of clinical and research work for benign esophageal diseases, such as the development of magnetic ring, double nedoscopic combination and new anti-reflux endoscopic techniques. In recent years, we have carried out high-resolution esophageal manometry and 24-hour pH/impedance monitoring for patients with interstitial pneumonia and pulmonary fibrosis suspected to be caused by gastroesophageal acid reflux. We can better assess the correlation between gastroesophageal reflux and pulmonary fibrosis, and to provide the different clinical treatments and even surgical interventions. The Bravo capsule is used more often in the United States, and it has obvious advantages over traditional approach for acid measurement. We strongly call for the collaboration between industry and academic institutions in this field, and the development of our own related products with independent intellectual property rights.

Journal of Nanjing University of Traditional Chinese Medicine 2025;41(8):993-997
This article summarizes Professor Tan Yong's approach to the treatment of polycystic ovary syndrome(PCOS)based on the lipid turbidity theory.It is believed that multiple factors such as improper diet,emotional injury,insufficient endowment,and im-proper work and rest lead to dysfunction of spleen and stomach,which cannot normally transport and transform water and grain essence and body fluid,and lipids cannot be effectively transformed and utilized,thus accumulating in the body to form lipid turbidity.Lipid turbidity is not only a pathological product but also an independent pathogenic factor,characterized by stickiness,concealment,heavy turbidity,lodging in collaterals,combined pathogenicity,and obstruction of qi and blood.Based on this theory,the etiology and patho-genesis of PCOS are explored,with its pathological progression divided into three stages:spleen deficiency and liver depression,phlegm and blood stasis,and kidney deficiency with lipid turbidity.In the early stage,impaired spleen transportation and liver disper-sion functions lead to lipid metabolism disorders,forming lipid turbidity.In the middle stage,lipid stagnation and obstruction of the meridians affect the circulation of qi and blood,leading to internal stasis and the formation of a pathological pattern of phlegm and blood stasis.In the later stage,prolonged illness affects the kidney,resulting in kidney qi deficiency,unresolved lipid turbidity,and imbal-ance of qi,blood,yin and yang,which leads to long-term metabolic and reproductive dysfunction.In terms of treatment,emphasis is placed on strengthening the spleen and eliminating turbidity,soothing the liver and nourishing blood in the early stage;eliminating phlegm and blood stasis,unblocking the collaterals and eliminating lipid in the middle stage;nourishing the kidney and replenishing essence,and regulating yin and yang in the late stage,providing new insights and theoretical basis for the integrated diagnosis and treatment of PCOS with traditional Chinese and Western medicine.

Objective To explore the clinical and pathological characteristics and oncological outcomes of clear cell borderline ovarian tumor(CCBOT),and provide guidance for the diagnosis and treatment of this disease in the future.Methods A total of 23 CCBOT patients who underwent surgical treatment in our hospital from May 2011 to Aug 2022 were enrolled,and the clinical information of 19 CCBOT patients in the Ricotta's cohort was integrated.The clinical pathological characteristics and oncological outcomes of these 42 patients were retrospectively analyzed.Results This study enrolled 42 CCBOT patients,including 23 from our cohort and 19 from the Ricotta G's cohort.Compared with the Ricotta's cohort,the proportion of CCBOT patients with endometriosis in our cohort(34.8%)was significantly higher than that in the Ricotta's cohort(5.3%)(P<0.05).In our cohort,22 patients had information on intraoperative frozen section evaluation,and the accuracy of intraoperative frozen section evaluation was 50%(11/22).The other 50%(11/22)of patients were underestimated by intraoperative frozen section evaluation.The merged cohort indicated that the median age of the patients was 60 years old,occuring more common in postmenopausal women(66.7%).Most cases presented with pelvic masses(59.5%)and abdominal pain or distension(19.0%).This disease mostly involved unilateral ovaries(90.5%).Information on preoperative tumor markers was largely missed,making it difficult to draw an accurate evaluation for them.Ten cases(23.8%)underwent fertility sparing surgery,and 32 cases(76.2%)underwent radical surgery.The pathologic report indicated that all patients were stage I patients and 21.4%patients had endometriosis.Among these patients,32 patients underwent total hysterectomy,of which 10(31.3%)had concurrent endometrial lesions.The median follow-up time was 68 months,with a minimum follow-up of one month and a maximum follow-up of 231 months,and no recurrence or death was observed.Conclusion CCBOT patients usually had an good prognosis with a low recurrence rate.Fertility sparing surgery was safe and feasible,but attention should be paid to exclude concurrent endometrial lesions.Given the rarity of CCBOT,future multicenter prospective studies are needed to better elucidate the clinical pathological features and prognosis of patients with CCBOT.
