To explore the correlation between MTHFR C677T gene polymorphism and hypertension, hyperhomocysteinemia(Hcy), and hyperlipidemia in the Tibetan population of Tibet. Using a cluster sampling method, participants from high-altitude regions including Ngari Prefecture, Lhasa City, and Nyingchi City in Tibet were enrolled. Differences in MTHFR C677T genotype distribution among individuals with hypertension, HHcy, and hyperlipidemia were analyzed, and multivariate logistic regression was performed to assess the association between these conditions and the TT genotype. A total of 574 eligible subjects were included, with a mean age of 40.64±12.67 years. Males accounted for 46.7%(268/574) and females 53.3%(306/574). Regional distribution was 34.8%(200/574) from Nyingchi City, 33.1%(190/574) from Lhasa City, and 32.1%(184/574) from Ngari Prefecture. Mean systolic and diastolic blood pressures were 117.89±18.98 mm Hg and 79.74±14.88 mm Hg, respectively. The frequency of the TT genotype was significantly higher in the hypertension group than in the non-hypertension group(12.32% The MTHFR C677T TT genotype is significantly associated with hypertension and hyperhomocysteinemia in the Tibetan population, suggesting that this polymorphism may be a genetic risk factor for these diseases in high-altitude regions.

OBJECTIVE:
To investigate the current status of clinical genetics specialization development and the diagnostic and therapeutic capabilities for hereditary diseases across medical institutions in Shanghai, and to assess the necessity and feasibility of establishing training bases for clinical genetics specialists.
METHODS:
By employing a cross-sectional survey design, the Clinical Genetics Committee of Shanghai Medical Association has conducted questionnaire surveys from March to April 2025 across 54 healthcare institutions in Shanghai (including 33 tertiary hospitals and 21 secondary hospitals). The survey involved administrative departments and medical personnel from 15 clinical specialties. The survey has covered current genetic disease diagnosis and treatment practices, relevant and specialised disease types, genetic department establishment, testing capabilities, personnel teams, and training requirements.
RESULTS:
The results revealed that 78.0% of clinical departments surveyed had treated patients with hereditary disorders. Shanghai possesses diagnostic and therapeutic expertise for over 95% of hereditary diseases listed in its rare disease catalogue, reflecting both the practical clinical demand for such conditions and the city's overall diagnostic and therapeutic strengths in this field. Nevertheless, significant disparities exist in the development of genetics departments across different tiers of healthcare institutions. Resources for genetic testing capabilities (including molecular, cellular, and biochemical testing) are also unevenly distributed across different tiers of hospitals. The survey further revealed that only 26.0% of departments believe that their current physician structure fully meets the diagnostic and treatment demands. Over 90% of departments consider standard training for clinical genetic specialists necessary, with 74.0% expressing willingness to participate in establishing training bases. Based on above findings and thorough deliberation, the Clinical Genetics Committee of the Shanghai Medical Association proposes advancing specialist training and discipline development through establishing a standard training system. The committee has drafted a three-year training protocol featuring a "joint training"-centered model, recommending a pilot-first, dynamically optimized strategy for steadily advancing training base development.
CONCLUSION
Shanghai faces substantial demand for genetic disease diagnosis and treatment, yet exhibits shortcomings in clinical genetics specialization development, resource allocation, and talent pipeline cultivation. To establish a standard training system holds significant practical importance and is underpinned by a broad demand.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).

With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

Objective To analyze the postoperative complications and survival outcomes of elderly patients with renal cell carcinoma undergoing laparoscopic surgery, and to identify the influencing factors, so as to provide reference for improving the safety of laparoscopic surgery in such patients. Methods A retrospective analysis was conducted on the clinical, surgical, and pathological data of 153 patients aged ≥75 years who underwent laparoscopic nephrectomy for renal cell carcinoma at our hospital during 2012 and 2025.Logistic regression analyses were performed to identify factors influencing postoperative complications, and a nomogram was constructed and validated to predict the complications.Kaplan-Meier method was used to draw the survival curve, and the effects of different surgical approaches on the prognosis and the survival difference in the age subgroups (75-<80 years, ≥80 years) were analyzed.Cox regression analyses were conducted to determine factors affecting survival outcomes. Results Among the 153 patients, 15 developed postoperative complications, including 5 severe cases. Multivariate logistic regression identified Charlson Comorbidity Index (CCI) ≥3 and prolonged operation time as independent risk factors for postoperative complications (P<0.05).The C-index of the logistic regression model constructed based on these factors (age, CCI≥3 and operation time) was 0.77 (95%CI:0.64-0.90), with an average absolute error of 1.6%.Subgroup analysis revealed superior overall survival in patients aged 75-<80 years undergoing partial nephrectomy compared to radical nephrectomy (P=0.005 6).No statistically significant difference in overall survival was observed among patients ≥80 years who received different surgical approaches (P=0.062).Multivariate Cox regression analysis identified preoperative low albumin levels, preoperative renal insufficiency, tumor diameter>4 cm, and pathological stage as independent risk factors for overall survival (P<0.05). Conclusion Laparoscopic surgery is safe and effective for elderly patients with renal cell carcinoma, with survival outcomes correlated to nutritional status, renal function, tumor size and pathological staging.Patients aged ≥80 years still derive surgical benefit, and no survival differences exist between different surgical approaches in this age group.

Objective:To systematically review qualitative studies on the experiences of musculoskeletal symptoms in breast cancer patients undergoing endocrine therapy, and to gain insights into the initiation, development, and effects of these symptoms, along with their implications for patients, to guide the creation of targeted strategies for symptom management.Methods:The qualitative studies on the experiences of musculoskeletal symptoms in breast cancer patients undergoing endocrine therapy were performed across several databases, which included the Cochrane Library, Joanna Briggs Institute Evidence based Healthcare Center Database, PubMed, Embase, CINAHL, Web of Science, Scopus, CNKI, Wanfang Data, and Chinese Biomedical Literature Database. The retrieval period was from the establishment of the database to April 30, 2024. The studies' quality was evaluated utilizing the iteration of the Joanna Briggs Institute Qualitative Assessment and Review Instrument designed for qualitative research. Data synthesis was carried out using Meta-aggregation techniques.Results:A total of 15 articles were included and 41 results were extracted, which were grouped into 11 new categories and integrated into 3 primary themes: the manifestation of bone and joint symptoms was highly unique and varied, prominently featuring experiences such as migratory joint pain, morning stiffness, and cramps affecting both large and small joints, frequently associated with functional limitations; these symptoms significantly influence patients' everyday activities and mental health, contributing to feelings of anxiety, avoidance behaviors, fear, and a reduction in overall quality of life; to manage the intricate nature of their symptoms, patients employ a variety of coping mechanisms, such as engaging in physical activity, taking dietary supplements, consulting about medications, and seeking support from external sources.Conclusions:During endocrine therapy for breast cancer, patients exhibit diverse characteristics of musculoskeletal symptoms, and the resulting fear of recurrence, avoidance behaviors, and anxiety have a negative impact on their psychological well-being and overall health. Healthcare professionals should take into account individual differences, such as age, menopausal status, type of endocrine therapy, medication adherence, and factors that may exacerbate or alleviate symptoms, in order to effectively predict, assess, and manage bone and joint symptoms during endocrine therapy.

Getah virus(GETV)is an arbovirus capable of infecting humans and vertebrates such as horses and pigs via blood-sucking mosquitoes,which is extremely harmful to the livestock indus-try.Current monitoring methods are time-consuming,costly,and dependent on specialized instru-ments.These characteristics hinder rapid detection in clinical samples.Therefore,the development of a simple,rapid,specific,and sensitive method for detecting GETV antigen is crucial for the pre-vention and control of GETV.In this study,a GETV E1 monoclonal antibody strain SD17/09-E1-mAb was prepared by a prokaryotic expression system for GETV E1 protein expression,and a col-loidal gold double-antibody sandwich assay encapsulating two strains of GETV E1 monoclonal an-tibody wasestablished.The results showed that the prepared colloidal gold test strips had good sen-sitivity and did not cross-react with other common porcine virus-positive tissue samples;the test strips had a high compliance rate with the IFA assay for GETV,and could be stored at 37 ℃ for one month and at room temperature for at least three months.In this study,a colloidal gold anti-surveillance test strip for rapid detection of GETV was successfully prepared,which provides a powerful tool for GETV detection.
