Tumorigenesis， invasion， and metastasis occur in the context of a persistent inflammatory microenvironment， and a variety of inflammatory factors can lead to the development of various tumors. Guided by the thought of "preventive treatment of disease" in TCM and the concept of tertiary prevention in modern medicine， it is of great significance to effectively intervene in the inflammatory stage of the disease， interrupt disease progression， prevent the occurrence of malignant tumors， and reverse the process of "inflammation-to-cancer transformation". Sinisan， a commonly used prescription in the Treatise on Febrile Diseases， has been widely applied in the treatment of precancerous lesions of the digestive system， demonstrating considerable advantages. This article reviewed literature from the past 20 years， summarizing the application of Sinisan in precancerous lesions of the digestive system from three aspects： the exploration of its prescription-syndrome relationship， clinical application， and mechanistic study. It is found that basic syndrome indications of Sinisan include harmonizing the Earth element to promote spleen-stomach transportation and transformation， soothing the liver and nourishing the Wood element to restore the smooth flow of Qi， and regulating Yin and Yang to relieve stagnation within the system. In clinical application， Sinisan has shown significant efficacy in atrophic gastritis and precancerous conditions such as intestinal metaplasia， gastric ulcer， ulcerative colitis， esophagitis， and pancreatitis. Mechanistic studies have revealed that Sinisan can inhibit inflammatory factors and improve the inflammatory microenvironment， inhibit cell proliferation and regulate apoptosis， exhibit anti-angiogenic and antitumorigenic effects， modulate immune function， and exert antioxidant effects. These mechanisms can be achieved by regulating pathways such as nuclear factor erythroid 2-related factor 2/heme oxygenase-1 （Nrf2/HO-1）， farnesoid X receptor （FXR）/Nrf2， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Takeda G protein-coupled receptor 5/cyclic adenosine monophosphate/protein kinase A （TGR5/cAMP/PKA）， interleukin-4/signal transducer and activator of transcription 6 （IL-4/STAT6）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， RhoA/Rho-associated protein kinase （RhoA/ROCK）， and transforming growth factor-β/Smad proteins （TGF-β/Smads）， confirming Sinisan's role in reversing the inflammation-to-cancer transformation. The current research status of Sinisan in precancerous lesions of the digestive system was thoroughly examined through the above three aspects， along with the identification of limitations and areas for improvement in current research. The aim is to provide a basis and support for future in-depth research on Sinisan， promote the development of new integrated treatment models combining TCM and Western medicine for precancerous lesions， and aid in the research and development of drugs related to precancerous lesions.

Objective To evaluate the impact of different exercise frequencies on the symptoms,quality of life,and duration of rehabilitative effects in patients with Parkinson's disease(PD).Methods A total of 90 PD patients(Hoehn and Yahr stage ≤3,receiving continuous dopaminer-gic stimulation)admitted in Department of Neurology of Chinese PLA General Hospital were en-rolled and randomly divided into groups G1,G2 and G3,with 30 participants in each group.They received rehabilitation exercises of Parkinson's Wellness Recovery(PWR)1 h per time,at differ-ent frequencies,that is,once(G1),twice(G2)and three times(G3)a week,for totally 6 months.Unified Parkinson's disease rating scale(UPDRS),levodopa equivalent dose,10-meter walk test(10-MWT),Fullerton advanced balance(FAB)Scale,trail making test-A(TMT-A),nine-hole peg test(9-HPT)and Parkinson's disease questionare-39(PDQ-39)were applied to evaluate the efficacy of the rehabilitation.Results The PDQ-39 score was significantly decreased in all the three groups after PWR exercise(P＜0.05,P＜0.01).Compared with the corresponding levels before intervention,the group G2 had obviously lower 10-MWT score and higher FAB score(P＜0.05),and the group G3 obtained notably decreased scores in UPDRS,UPDRS-Ⅲ,10-MWT,TMT-A,9-HPT,and PDQ-39[30.72±11.31 vs 31.41±10.42,P=0.001;19.21±9.72 vs 20.17±8.80,P=0.001;7.38(6.26,8.49)s vs 7.48(6.53,8.56)s,P=0.004;53.97±8.74 s vs 54.07±8.62 s,P=0.026;38.71(33.71,49.71)s vs 38.90(33.78,49.82)s,P=0.001;28.00(14.50,36.00)vs 30.00(15.50,38.50),P=0.001],and increased FAB score[23.00(16.00,33.00)vs 21.00(16.00,32.00),P=0.005].In addition,the patients in the G3 group experienced the most pronounced re-habilitation effect immediately after exercise,but,all aforementioned indicators remained augmen-ted even 4 weeks after exercise.Conclusion Exercise rehabilitation three times weekly can greatly enhance the motor function of PD patients,ameliorate non-motor symptoms,and the overall quali-ty of life,with the beneficial effects persisting for a minimum of 4 weeks.

Objective To analyze the research hotspots and frontier trends in the field of physical therapy for Parkinson's disease(PD)from 2014 to 2023.Methods Relevant literatures published from January,2014 to December,2023 were retrieved from the Web of Science Core Collection.CiteSpace 6.3.R1 was used to conduct bibliometric analysis,generating visual maps of coun-tries,institutions,keyword co-occurrence,burst terms,timelines and clustering,and they were summarized based on both visual results and literature content.Results A total of 400 articles were included.The United States had the highest publication volume,followed by China,Italy and Brazil,and the international collaboration was relatively active.Major contributing institutions included Northwestern University,Rush University,Karolinska Institutet and Universidade de S?o Paulo.Keyword co-oc-currence analysis showed that researches mainly focused on interventions such as exercise,postural control,aero-bic exercise and transcranial direct current stimulation.Burst detection analysis showed that keywords with high attention in recent years included motor symptoms,executive function,resistance training and noninvasive brain stimulation.The timeline map indicated a shift in research themes from early focus on electrical stimulation to in-tegrated interventions involving both motor and cognitive functions.Conclusion Over the past decade,researches on physical therapy for PD has shown steady growth,with increasing diver-sity in intervention strategies.There is a clear trend toward multidimensional integration and interdisciplinary col-laboration.Future studies should strengthen interventions targeting non-motor symptoms and promote the clinical application of new rehabilitation technologies.

Objective:To systematically evaluate the current status of research on the development of indicators for entrustable professional activities (EPAs) of residents in China.Methods:We searched the China National Knowledge Infrastructure, Wanfang Data, Airiti Library, PubMed, Embase, and Web of Science databases for literature on the development of EPA indicators for residents in China published between January 1, 2005 and February 28, 2025. Two researchers independently screened the literature and extracted data, followed by descriptive analysis. The quality of the studies was assessed using the Joanna Briggs Institute critical appraisal tool for expert opinion. Quantitative data were presented as medians (ranges) and qualitative data were presented as frequencies (percentages).Results:A total of eight articles were included, in which two general EPA indicator systems and six specialty-specific EPA indicator systems were developed for residents. The overall quality of the research was high, with the main shortcomings related to the methods used in the process of constructing the consensus indicators. The number of experts recruited ranged from 22 to 45, with 100.00% response rate, high authority coefficients (0.820-0.914), and high coordination coefficients (0.157-0.741). Most of the studies used literature reviews as one source for the indicator pool (8 studies, 100.00%), employed the Delphi method to reach consensus (6 studies, 75.00%), and provided inclusion criteria for the indicators (7 studies, 87.50%). However, only one study (12.50%) explored the practical application of the developed indicators, and none of the studies set indicator weights or conducted quality assessments. The number of EPA indicators developed ranged from 10 to 38 per study. The reporting of EPA indicators was included in most studies regarding titles (8 studies, 100.00%) and the expected levels of entrustment at various stages of training (6 studies, 75.00%), but the reporting on other aspects was lacking. Among the specialty-specific EPA indicators, 38.39% overlapped with the general EPAs indicators.Conclusions:The research on the development of EPA indicators for residents in China is still in its early stages, and there is room for improvement in methodological quality and reporting coverage. There is partial overlap between specialty-specific and general EPA indicators, failing to fully reflect the unique characteristics of different specialties.

Objective:To compare the accuracy of a Chinese large language model (LLM) and radiologists in Chinese middle level professional qualification examination of radiology, and evaluate the quality of answer reasoning provided by the Chinese LLM.Methods:In this study, 100 high-quality questions were selected using stratified random sampling to form a test set. We asked the ERNIE Bot by dialogues on the website to provide the correct answers and answer reasoning for these questions. These questions were also answered by 15 radiologists with different levels of experience. The accuracy of Chinese LLM and that of radiologists were compared. Two radiologists evaluated the quality of answer reasoning using a 5-point semi-quantitative scale.Results:The accuracy of ERNIE Bot was 60.00%, which was lower than the median (interquartile) accuracy of 67.00% (64.00%, 73.00%) for radiologists, and the difference was statistically significant ( W=2.47, P=0.013). The word count of the reasoning provided by Ernie Bot was (196.44±99.25) words, with no significant difference in word count between correct and incorrect answer reasoning, which were (211.03±107.53) words and (174.55±81.84) words, respectively ( t=1.82, P=0.072). Among the correct answers, the quality of reasoning was scored as follows: 1 point for 3 questions, 2 points for 9 questions, 3 points for 12 questions, and 4 points for 36 questions. No reasoning received a score of 5. Conclusions:Chinese LLM demonstrates a certain level of medical knowledge and clinical reasoning ability, which can assist clinical teachers in educational activities. However, it is not yet able to independently tutor residents and lacks the ability of invitational and heuristic teaching.

Objective:To investigate the current status of Chinese-foreign cooperative education programs for medical majors, and to discuss the potential problems and development trends of this field.Methods:Related data were collected from the information platform of Chinese-Foreign Cooperation in Running Schools by Ministry of Education of the People's Republic of China, and the characteristics of Chinese-foreign cooperative education programs for medical majors were extracted for analysis. Categorical data were expressed as frequency (percentage), and continuous data were expressed as mean±standard deviation.Results:A total of 83 Chinese-foreign cooperative education programs for medical majors were included in the study, accounting for only 3.45% (83/2 406) of all programs. Chinese partners in these cooperative programs were mainly from East China (41 programs, 49.40%), while foreign partners were mainly from Europe (39 programs, 46.99%). The mean duration of these programs was (3.61±0.88) years, with an enrollment of (87.08±35.52) students. Most of the students were included in National General Higher Education Enrollment Plan (79 programs, 95.18%), and the main majors included nursing (39 programs, 46.99%), medical technology (19 programs, 22.89%), and clinical medicine (11 programs, 13.25%), with the main enrollment level of junior college (45 programs, 54.22%). Chinese partners in the cooperative programs mainly issued academic certificate (45 programs, 54.22%) or academic certificate plus degree certificate (36 programs, 43.37%), while most foreign partners did not issue such certificates (44 programs, 53.01%).Conclusions:There are several problems in Chinese-foreign cooperative education programs for medical majors, such as a limited number of programs, a significant regional difference, an imbalanced distribution of specialties, a low level of education, and inconsistency in issuance of certificates, which still requires further improvement and standardization. However, there are also high-level and high-quality programs for reference.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.
