Resumo Introdução: o pensamento repetitivo negativo (PRN) pode ser caracterizado como pensamentos intrusivos sobre preocupações (atuais, passadas ou futuras), experiências negativas e autocríticas, manifestando-se de forma excessiva e persistente. Em um processo transdiagnóstico, identifica-se que o PRN contribui para o aparecimento e manutenção de transtornos múltiplos. O presente estudo objetivou adaptar a Persistent and Intrusive Negative Thoughts Scale (PINTS) para o contexto brasileiro, averiguando as qualidades psicométricas do instrumento. Método: procedeu-se a dois estudos com participantes de diferentes estados brasileiros. No estudo 1 (n = 258), foi realizada a adaptação da PINTS e uma análise fatorial exploratória. No estudo 2, (n = 270), foi realizada uma análise fatorial confirmatória além de reunidas evidências de validade convergente. Resultados: primeiramente, o estudo 1 apontou uma estrutura unifatorial da medida. A partir do estudo 2, foram corroboradas a estrutura unifatorial e a adequada consistência interna (precisão), o que demonstrou que a PINTS se relacionou positivamente com a afetividade negativa (estresse, ansiedade e depressão) e com a ansiedade cognitiva de provas. Conclusão: conclui-se que a PINTS apresentou qualidades métricas satisfatórias, sendo uma medida curta e de fácil aplicação, podendo ser uma ferramenta útil para pesquisadores que buscam investigar o PRN desadaptativo e os seus correlatos.
Abstract Introduction: Repetitive Negative Thinking (RNT) can be characterized as intrusive thoughts about worries (current, past, or future), negative experiences, and self-criticism, manifesting excessively and persistently. In a transdiagnostic process, it is identified that the RNT contributes to the onset and maintenance of multiple disorders. The present study aimed to adapt the Persistent and Intrusive Negative Thoughts Scale (PINTS) for the Brazilian context, investigating the psychometric qualities of the instrument. Method: Two studies were carried out with participants from different Brazilian states. In Study 1 (n = 258), the adaptation of PINTS and an exploratory factor analysis was performed. In Study 2 (n = 270), a confirmatory factor analysis was conducted, and evidence of convergent validity was gathered. Results: Firstly, in Study 1, a unifactorial structure of the measure was indicated. Through Study 2, the unifactorial structure was corroborated, demonstrating adequate internal consistency (precision), demonstrating that PINTS positively correlated with negative affectivity (stress, anxiety, and depression) and cognitive test anxiety. Conclusion: It is concluded that PINTS exhibited satisfactory metric qualities, being a brief and easy-to-administer measure, potentially serving as a useful tool for researchers investigating maladaptive repetitive negative thinking and its correlates.

Resumen Este ensayo cuestiona, a propósito de la medicina, la idea de progreso como desarrollo tecnológico al centrarlo en las personas y no en las cosas. Se analiza cómo el predominio de tal idea de progreso convierte a las sociedades actuales al tecno-fetichismo que degrada la vida comunitaria y la práctica médica contribuyendo a la medicalización de la vida social. Se argumenta que la realización de las potencialidades tecnológicas depende de sus formas de uso, que el móvil principal del desarrollo tecnológico es el lucro sin límites, y que los desarrollos prioritarios son los que potencian el control social que mantiene el statu quo. Se critica la idea de inteligencia como cociente intelectual al proponerla como atributo del ser humano como un todo, manifiesto en las formas pensar y proceder de las personas en sus circunstancias, donde la afectividad y el pensamiento crítico son imprescindibles para su desarrollo. Se destaca que su antecedente es el concierto armónico de la vida planetaria contrastante con la disarmonía humana imperante. Se plantea que la inteligencia artificial es la más reciente hechura del tecno-fetichismo que deposita en la tecnología atributos vitales, y que sus formas de uso acentuarán la degradación de la vida humana y planetaria. Se propone otra idea de progreso médico basado en formas de organización propicias para el desarrollo de aptitudes inquisitivas, críticas y colaborativas que impulsen la superación permanente, cuyo horizonte lejano es el progreso dignificante: sublimación espiritual, intelectual, moral y convivencial de las colectividades en armonía con el ecosistema planetario.
Abstract This essay questions, with regard to medicine, the idea of progress as technological development by focusing on people rather than things. It analyzes how the predominance of such an idea of progress converts todays societies to techno-fetishism that degrades community life and medical practice, contributing to the medicalization of social life. It is argued that the realization of technological potentialities depends on their forms of use; that the main motive of technological development is unlimited profit and that priority developments are those that enhance the social control that maintains the status quo. The intelligence as an intelligence quotient is criticized by proposing it as an attribute of the human being as a whole, manifested in the ways of thinking and proceeding of people in their circumstances, where affectivity and critical thinking are essential for their development; it is emphasized that its antecedent is the harmonic concert of planetary life that contrasts with the prevailing human disharmony. It is proposed that artificial intelligence is the most recent creation of techno-fetishism that deposits vital attributes in technology and that its forms of use will accentuate the degradation of human and planetary life. Another idea of medical progress is proposed, based on forms of organization conducive to the development of inquisitive, critical and collaborative skills that promote permanent improvement, whose distant horizon is dignifying progress: spiritual, intellectual, moral and convivial sublimation of collectivities in harmony with the planetary ecosystem.

Background: Medical education shifts from a teacher-centered to a student-centered which fosters self-directed learning, critical thinking, and problem-solving skills, especially in the scenario of a large classroom. Flipped classroom is a blended learning to increases student engagement with content, improves faculty contact time with students, and enhances learning. This study was conducted to compare the effectiveness of the flipped classroom method and didactic lecture on students’ performance and to obtain students’ and teachers’ perceptions in teaching-learning biochemistry. Methods: All participant students were randomly divided into two groups and subjected to the FC method and TDC method in module A and a crossover of groups was done in module B. Both groups were subjected to pre and post-tests after intervention in modules. Feedback was obtained from students and teachers on both learning methods. Results: There was a statistically significant difference (P < 0.0001) after applying independent t-test in pre and post-test scores and module completion test in both learning methods. About 91% of participants were satisfied with using a flipped classroom and found it more enjoyable, creates interest in the subject, whereas faculties’ feedback shows it requires more efforts and time. Conclusions: Considering responses and results of the assessment, it can be concluded that the FC approach, effectively engage students in the learning process, inculcation the attributes to develop self-directed and lifelong learning skills. Also improved the students’ performance and perceptions of the learning experience. Most of the students indicate that this approach is worth to use in future.

In the context of the current era when different civilizations are learning from each other， traditional Chinese medicine （TCM） needs to continuously draw the essence from modern scientific and technological civilization for creative inheritance and innovative development. It is essential to master the classic texts of TCM to solidify its theoretical foundation， while also read extensively to broaden the academic horizons. TCM's inheritance and innovation should be integrated with the current era's context and social reality， and delve into the essence of TCM's academic experience and clinical practice. Emphasis should be placed on the inheritance of original TCM thinking， and return to the original image creation and transformation. Using image thinking as the main approach， and combined it with modern complex systems science and front-edge methodologies， we could elaborate the TCM theories such as correspondence between nature and human， five circuits and six qi， constitution and endowment， and harmony of body and spirit. The training of academic talents must be at the forefront， closely follow the new trends of the development of contemporary scientific and technological civilization， identify the “pain points” of discipline development， focus on the key areas for improvement， and seek the highlights of academic research. There should be a courage to question and propose new insights， construct new concepts， establish new theories， transform the weakness in original theoretical innovation， and enrich the evolving connotation of TCM.

The modernization of traditional Chinese medicine （TCM） theories is not only a prerequisite for the modernization of TCM but also a way to deal with the external environment and the difficulties of its development. The modernization of TCM is based on the premise of maintaining its own characteristics and advantages， and along with the progress of modern science and technology， the entire TCM has undergone new changes and improvements from theory to practice， and has become a scientific system with modern scientific level that adapts to the needs of the times. In the context of the unprecedented profound changes in contemporary TCM academics， this paper puts forward the definition of modernization of TCM theory and argues that the modernized theoretical system of TCM should maintain originality to build the foundation of TCM inheritance， clarify the frontier of the discipline and establish the conceptual system， form an open network to be compatible with multi-disciplinary interaction， incorporate the falsification and establish self-renewal system， creatively transform and innovatively develop， and modernize the interpretation and update the discourse system.

Objective:To construct an evaluation system for clinical thinking ability of general practitioners in the treatment of multimorbidity.Methods:This was a cross-sectional study. The draft of evaluation indexes for clinical thinking ability of general practitioners in treatment of multimorbidity was preliminary developed through literature review, collation, analysis and discussion. Nineteen clinical and teaching experts of general practice were selected for consultation via anonymous convenient sampling. From January to June 2022, 2 rounds of expert consultation were conducted using the Delphi method. During the first round of consultation, according to the survey feedback, we modified and improved the evaluation system of general practitioners′ clinical thinking ability for multi-disease co-treatment. During the second round, experts were asked to assess the importance of each index, and to calculate the weight of each index accordingly. Questionnaires were sent to experts via letters. The content of the questionnaires encompasses the basic information of experts, evaluation for various indexes and relevant opinions. The mean value of importance assignment ≥3.5, coefficient of variation ≤0.25 and the full score frequency ≥30% were taken as the criteria. Indexes unsatisfying the criteria were removed, so that the final index system could be constructed.Results:The average age of 19 experts was 50.2 years old, 9 of them were male. A total of 2 rounds of expert consultation were conducted, 19 questionnaires were issued in each round, and 19 effective questionnaires were received afterwards. In the first round of consultation, 10 experts put forward revised opinions, and some indexes were adjusted according to the definition criteria and the discussion of the research group. In the second round of consultation, 3 experts put forward suggestions for modification. According to the definition criteria, no need to delete the indexes. After discussion by the research group, some indexes were adjusted, and finally an evaluation system of clinical thinking ability for multi-disease co-treatment of general practitioners was established, including 4 first-level indexes and 30 second-level indexes. The weights of the 4 first-level indexes in descending order were "overall thinking ability" (38.01%), "diagnostic thinking ability" (33.96%), "evidence-based thinking ability" (14.75%), and "critical thinking ability" (13.28%). Among the 30 secondary indexes, the top 5 were "ability to identify and handle priority emergency incidents" (5.04%), "risk assessment and critical illness identification ability" (4.63%), "emergency referral ability" (4.61%), "communication and expression ability" (4.57%), and "standardized diagnosis and treatment ability" (4.23%).Conclusion:This study successfully constructed an evaluation system for clinical thinking ability of general practitioners in the treatment of multimorbidity.

The essence of asymptomatic syndrome differenciation is that the disease is in a special stage or state. To perform traditional Chinese medicine （TCM） diagnosis when there was no symptoms for differentiation is a key scientific issue in current TCM diagnosis and treatment. The reasons include limitations in doctor-patient behaviors and relationships， as well as limitations in cognitive thinking. To address such situations， the following strategies can be adopted from a thinking perspective，i.e. grasping the occurrence and development of diseases based on a holistic concept， using dialectical thinking to summarize the laws of diseases， integrating clinical practice with experiential thinking， and introducing new thinking modes through interdisciplinary collaboration. These strategies help TCM practitioners make accurate diagnoses in the absence of obvious symptoms， thereby providing better medical services for patients.

The current interdisciplinary research on traditional Chinese medicine （TCM） often comes from the simple combination of TCM application needs and mature engineering technology. Actually， higher goal of cross-disciplinary research should be the win-win development of TCM and interdisciplinary majors. In detail， to enhance the innovative development of original thinking mode of TCM， meanwhile， to stimulate the innovation of interdisciplinary majors with medical tasks. Previously， we successfully performed the research on the objective representation of pre-disease and disease state of dyslipidemia in population with phlegm-dampness constitution. Taking this project as an example， this paper discusses the methodology on scientific issue positioning， key medical tasks selection， interdisciplinary theory， and technology exploration， to expounds the research design and ideas which could be generalized in other cross-disciplinary research of TCM.

Based on the theory of “manifestation-body and spirit-qi”， it is considered that the pathogenesis of tic disorders （TD） involves three manifestations of “wind， phlegm and fire”， with wind as the leading factor and phlegm and fire as the accompanying factors. It is advocated to identify the abnormality of body and spirit， summarize the evolution of manifestation， and prescribe flexibly based on qi movement of zang-fu organs. Among them， the common symptoms related to tics are mostly belong to wind symptoms， which originated from lung qi failing to purify and liver qi over-ascent. The method of soothing liver wood and purifying lung gold is adopted， and modified Xiaochaihu Decoction （小柴胡汤） and Cangerzi Powder （苍耳子散） are recommended； Patients with prolonged illness and strange symptoms are often mixed with phlegm， which stemmed from the fact that spleen failing to rise clear and stomach failing to downward turbid. The method of raising spleen-earth and lowering stomach-earth is adopted， and modified Yigong Powder （异功散） and Erchen Decoction （二陈汤） are recommended； Patients with severe symptoms are often mixed with fire symptoms， which originated from discordance of water and fire and hyperactivity of heart fire. The method of interacting heart and kidney and coordinating water and fire is adopted， and modified Xiegan Pill （泻肝丸） and Liuwei Dihuang Pill （六味地黄丸） are recommended， in order to regulate qi movement， harmonize body and spirit， and improve the symptoms.

Objective@#To explore the mediating effect of rumination between life events and learning value doubt among junior high school students, so as to provide reference for the psychological health education of junior high school students.@*Methods@#From March to July 2023, a total of 930 junior high school students from Guangdong, Jiangsu and Hebei were selected by a combination of convenient sampling methods. Participants completed the Scales of Value of Learning (SVL), Ruminative Response scale (RRS) and Adolescent Self rating Life Events Checklist (ASLEC). The t test and ANOVA were used for inter group comparisons and Pearson correlation analysis was used for correlation analysis and bootstrap method was used for mediating effect test.@*Results@#The life events of junior middle school students were positively correlated with learning value doubt ( r =0.18), rumination ( r = 0.65 ) and its three dimensions (brooding, reflective pondering, and symptom focused rumination) ( r =0.60, 0.59, 0.66). Learning value doubt was positively correlated with rumination ( r =0.15) and its three dimensions ( r =0.07, 0.13, 0.19) ( P <0.05).The symptom focused rumination (effect size=0.09, 95% CI =0.06-0.11) and brooding (effect size=-0.07, 95% CI =-0.09--0.04) dimensions partially mediated the relationship between life events and learning value doubt. In the two influential pathways, symptom focused rumination exerts a stronger impact, and the difference was statistically significant (effect size=0.15, 95% CI =0.11- 0.20 , excluding 0) ( P <0.05).@*Conclusions@#Life events experienced by junior high school students can positively predict learning value doubt through symptom focused rumination, and negatively predict learning value doubt through brooding. Active attention should be paid to the mental health status of junior high school students, intervene promptly when they experience life events, reduce symptom based rumination, and improve their learning enthusiasm.

Objective:To investigate the application value of the teaching evaluation method guided by cultivating "excellent doctors" in the clinical teaching of dermatology and venereology.Methods:A non-simultaneous control study was conducted, and the medical students who received theoretical learning and clinical internship in Department of Dermatology and Venereology, Affiliated Hospital of North Sichuan Medical College, from March 2020 to February 2022, were enrolled as subjects. According to the order of enrollment, 32 students who were enrolled from March 2020 to February 2021 were set up as control group, and 31 students who were enrolled from March 2021 to February 2022 were set up as experimental group. The students in the control group received lecture-based learning, and those in the experimental group received clinical teaching using a teaching and evaluation method guided by cultivating "excellent doctors". After the course ended, the two groups were compared in terms of the scores of theoretical knowledge and operation skills, clinical thinking ability [Self-Assessment of Clinical Reasoning and Reflection (SACRR)], core competence [Mini-Clinical Evaluation Exercise (Mini CEX)], and degree of satisfaction with teaching. SPSS 25.0 software was used to perform the independent samples t-test, the Mann-Whitney U test, the chi-square test, and the rank sum test. Results:One student in the control group voluntarily withdrew from the study, and one student in the experimental group did not complete the contents of internship. Finally, 31 students in the control group and 30 in the experimental group were included in the study. After 4 weeks of internship, compared with the control group, the experimental group had significantly higher scores of theoretical knowledge (88.00±4.30 vs. 85.71±4.12, t=2.12, P=0.040) and operation skills (91.87±3.99 vs. 88.23±3.84, t=3.63, P<0.05). After 4 weeks of internship, compared with the control group, the experimental group had significantly higher information systematization score (47.23±3.11 vs. 45.16±3.00), analysis problem score (34.87±2.30 vs. 31.29±2.30), truth finding score (16.30±1.49 vs. 14.45±1.52), reflective ability score [3.50 (3.00, 4.00) vs. 3.00 (3.00, 3.00)], and total score of SACRR (101.87±4.47 vs. 93.90±4.47), with significant differences between the two groups ( t/ Z=2.65, 6.17, 4.79, 3.15, and 6.96, all P<0.05). After 4 weeks of internship, the experimental group had a significantly better core competence than the control group ( Z=2.12, P=0.030); compared with the control group, the experimental group had significantly higher classroom teaching score (20.17±1.98 vs. 18.45±2.23, t=3.17, P<0.05), clinical practice score (19.83±2.10 vs. 17.65±2.17, t=4.00, P<0.05), learning plan score (18.63±2.24 vs. 17.03±2.15, t=2.85, P<0.05), teaching resource score (20.07±1.82 vs. 18.58±2.00, t=3.04, P<0.05) and total score (78.70±3.67 vs. 71.71±4.13, t=6.98, P<0.05). Conclusions:The application of the teaching and evaluation method guided by cultivating "excellent doctors" in the clinical teaching of dermatology and venereology can improve clinical theoretical knowledge, practical operation skills, clinical thinking ability, and core ability among interns and thus help to improve teaching quality. Therefore, it holds promise for clinical application.
