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.

Humanistic caring for patients in the operating room refers to providing the whole process of caring medical services for patients in the operating room. In order to standardize humanistic caring services for patients in the operating room of medical institutions, improve the comprehensive service level of the operating room, and enhance the surgical experience of patients, the Chinese Association for Life Care released the group standard " Humanistic Caring Management Standards for Patients in the Operating Room" in December 2023. This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Objective To investigate the demand for postoperative follow-up care services among patients after outpatient surgery,to optimize the care service process,and to enhance the quality of outpatient care,so as to ensure timely and effective follow-up care after outpatient surgery and improve their satisfaction and rehabilitation outcomes.Methods A total of 156 patients who underwent outpatient surgical procedures at Navy 971 Hospital from January 2023 to December 2023 were enrolled as research subjects through convenient sampling.A self-designed questionnaire was used to investigate the general information of patients,their demand for postoperative follow-up care,and the recognition of follow-up care forms.The questionnaires were distributed and collected by professional personnel of the outpatient surgery room.The related service items of follow-up care were statistically analyzed using percentages and descriptive analysis.Results Of the 156 questionnaires distributed,all(100%)were returned and valid.Among the patients undergoing outpatient surgery,91.7%required follow-up care services.The follow-up care services with the highest demand among naval vessel personnel were self-observation and care guidance for wounds(90.4%),seeking help for wound discomfort(86.5%),and postoperative follow-up and health education(75.6%).The most recognized forms of follow-up care services were telephone follow-up(88.5%),remote consultation(76.3%),and on-site visits by medical teams(62.2%).Conclusion There is a high demand for follow-up care services among patients after outpatient surgery.Hospitals should establish a complete follow-up care service model and care teams based on the actual needs of patients and the requirements of health education,and formulate personalized follow-up care plans.

OBJECTIVE To investigate the stability of 5-fluorouracil （5-FU） in human blood and to establish a standardized clinical sampling and delivery procedure for therapeutic drug monitoring （TDM） of 5-FU. METHODS The EDTA-anticoagulated whole blood was used as the matrix to prepare stability assessment samples of 5-FU at both low （200 ng/mL） and high （5 000 ng/mL） concentrations （with groups without stabilizer and with 1% volume ratio of stabilizer）. The stability assessment samples were placed under room temperature （[ 25±2） ℃] and refrigerated （2-8 ℃） conditions， with sampling at 0， 0.5， 1， 2， 4， 7， and 24 h. After vortexing and centrifugation， the upper plasma layer was collected； proteins were precipitated using methanol， and the concentration of 5-FU in plasma was determined by liquid chromatography-tandem mass spectrometry. Based on the whole blood stability results， clinical sampling and delivery procedures were established. RESULTS The concentration of 5-FU in blank whole blood samples without stabilizers was significantly lower than that in samples with stabilizers （P＜0.05）. However， varying volumes （10， 25， 50 μL） of stabilizers had no significant effect on the measured concentrations of 5-FU in stability assessment samples with low and high concentrations （P＞0.05）. Without the addition of a stabilizer， low- and high-concentration 5-FU whole blood samples remained stable at room temperature for 0.5 h and 1 h， respectively， and under refrigeration for 2 h and 7 h， respectively. After the addition of a 1% stabilizer， the whole blood samples remained stable for up to 24 h under both room temperature and refrigerated conditions. Based on these findings， the following procedure was established： after collection， whole blood samples could be temporarily stored at room temperature （≤0.5 h） or at 4　℃ （≤2 h）， and transported at 2-8　℃. Upon delivery to the laboratory， a 1% volume ratio of stabilizer must be added immediately， followed by centrifugation within 24 h. The resulting plasma should be stored at －20 ℃ . CONCLUSIONS 5-FU in whole blood exhibits poor stability at room temperature. Refrigeration at 2-8　℃ slightly improves stability ， but degradation still occurs rapidly. Adding a stabilizer at a 1% volume ratio significantly prolongs the refrigerated storage time. The established sampling and transport procedure for 5-FU TDM innovatively introduces the stabilizer addition step at the laboratory sample reception stage （rather than immediately after blood draw）. This approach ensures analytical quality while offering greater adaptability to real-world clinical sampling conditions， significantly improving practical feasibility.

Objective:To explore the value of deep learning models based on ultrafast dynamic contrast-enhanced MRI (UF-DCE MRI) in predicting malignant breast lesions.Methods:The study was a cross-sectional study. Clinical and imaging data of 347 patients with breast lesions who received treatment at Tianjin Medical University Cancer Institute and Hospital from March 2023 to January 2024 were analyzed retrospectively. A total of 347 lesions were observed in the 347 patients, including 75 benign and 272 malignant lesions. The random number method was used to divide into the training set with 243 cases and the validation set with 104 cases in a ratio of 7∶3. All patients underwent breast UF-DCE MRI and conventional dynamic-enhanced MRI (DCE-MRI). A 27-channel model (27-phase enhancement images of input UF-DCE MRI), a 3-channel model (3-phase enhancement images of input DCE-MRI), and a 1-channel model (1st-phase enhancement images of DCE-MRI) were built based on the pre-trained ResNet18 deep learning model on ImageNet. The efficacy of each model in predicting breast malignant lesions was analyzed using receiver operating characteristic curves and area under the curve (AUC). The differences of AUC were compared using DeLong test.Results:In the training and validation sets, the 27-channel model had the highest AUC for diagnosing malignant breast lesions, which were 0.848 (95% CI 0.818-0.877) and 0.784 (95% CI 0.752-0.817), respectively. DeLong test showed no statistically significant difference in the AUC values of the three models in the validation set for the diagnosis of malignant lesions of the breast in a two-by-two comparison ( P>0.05). UF-DCE MRI scans were 27 phases totaling 81 s with a temporal resolution of 3 s/phase; DCE-MRI scans were 3 phases totaling 270 s with a temporal resolution of 90 s/phase. Conclusions:The model combining UF-DCE MRI with deep learning demonstrates comparable efficacy to DCE-MRI deep learning model in diagnosing breast malignant lesions. However the UF-DCE MRI has the advantages of high temporal resolution and short scanning time, which makes this model valuable for precise diagnosis and treatment of breast cancer.

Acute-on-chronic liver failure （ACLF） refers to severe liver dysfunction that occurs on the basis of chronic liver diseases， and it is characterized by rapid disease progression， poor prognosis， and high mortality rate. In recent years， inflammatory markers have become a research hotspot due to their significant role in assessing the prognosis of ACLF. This article reviews the advances in the application of inflammatory markers in assessing the prognosis of ACLF， such as systemic immune inflammatory index， lymphocyte-white blood cell ratio， neutrophil-lymphocyte ratio， and C-reactive protein， and discusses their clinical value and future research directions， in order to provide a theoretical basis for the early intervention and prognosis management of ACLF patients.

Objective:To investigate the association between photodynamic diagnosis(PDD)and treatment efficacy of 5-aminolevu-linic acid(ALA)photodynamic therapy(PDT)in patients with cutaneous squamous cell carcinoma in situ(cSCCis).Methods:A pro-spective cohort study was conducted among the patients with cSCCis who underwent ALA-PDT in Department of Dermatology,Huashan Hospital,Fudan University,from January 2020 to November 2024.All patients were diagnosed with cSCCis based on biopsy,and invasive squamous cell carcinoma was excluded.Clinical information was collected and PDD was performed before treatment,and the patients were divided into moderate fluorescence group and strong fluorescence groups based on fluorescence intensity.All patients received six sessions of PDT treatment at an interval of 1-2 weeks.The primary endpoint was the initial complete clearance rate at 3 months after the last treatment session,and secondary endpoints were the sustained complete clearance rate at 12 months after the last treatment session and treatment failure rate.The multivariate regression analysis,the survival curves,and the Cox regression analysis were used to investigate the association between PDD fluorescence intensity and treatment efficacy,as well as other influencing factors for treatment efficacy.Results:Compared with the strong fluorescence group,the moderate fluorescence group had significantly lower initial complete clearance rate[57.14%(8/14)vs.93.33%(28/30),odds ratio OR=0.100,P=0.010]and sustained complete clearance rate[42.86%(6/14)vs.76.67%(23/30),OR=0.230,P=0.030)].The multivariate regression analysis showed that moderate fluores-cence was an independent risk factor for initial complete clearance(OR=0.030,P=0.030).The moderate fluorescence group had a significantly higher treatment failure rate than the strong fluorescence group[57.14%(8/14)vs.23.33%(7/30),P=0.030].The survival analysis and the Cox regression analysis showed that moderate fluo-rescence was an independent risk factor for PDT treatment failure(hazard ratio=3.040,P=0.048).There were no significant differences in adverse reactions between the two groups.Conclusion:PDD fluorescence intensity can predict the efficacy of ALA-PDT in patients with cSCCis.Moderate fluorescence indicates a higher risk of treatment failure,which can help to guide clinicians in develop-ing individualized treatment strategies.

Purpose To explore the correlation between spectral CT-derived quantitative parameters and different programmed death-ligand 1(PD-L1)expression status in gastric adenocarcinoma,in order to provide additional imaging-based references for immunotherapy regimen selection in patients with this disease.Materials and Methods A total of 45 patients with gastric adenocarcinoma,pathologically confirmed by biopsy,who underwent PD-L1 testing prior to treatment were retrospectively enrolled from Lanzhou University Second Hospital between January 2021 and September 2023.All patients underwent baseline spectral CT scans.Based on PD-L1 expression status,patients were categorized into the higher combined positive score(CPS)group(CPS≥5)and the lower CPS group(CPS<5).From the single-energy images of arterial and venous phases,the CT values(CT40 keV,CT70 keV),effective atomic number,and iodine concentration of the lesions were measured.The standardized iodine concentration and slope of the spectral curve were calculated.Differences in spectral CT parameters between the two groups were compared.Receiver operating characteristic curves were plotted for parameters with statistically significant differences,and the area under the curve was calculated to evaluate the efficacy of each single parameter and combined parameters in distinguishing PD-L1 expression status.Results In the arterial phase,the CT40 keV,CT70 keV,iodine concentration,standardized iodine concentration,effective atomic number,and slope of the spectral curve of lesions in the higher expression group were all significantly higher than those of lesions in the lower expression group(t/Z=-3.115 to-2.725,all P<0.05),whereas no significant differences were observed in all parameters in the venous phase(all P>0.05).For the standardized iodine concentration in the enhanced arterial phase,the area under the curve for distinguishing PD-L1 expression status was 0.755(95%CI 0.612 to 0.898),with a sensitivity of 81.8%and a specificity of 65.2%.No significant differences were found between it and other single spectral CT parameters in the arterial phase(all P>0.05),and its diagnostic efficacy was similar to that of the combined parameters[the area under the curve was 0.755(95%CI 0.613 to 0.897),sensitivity was 90.9%,specificity was 52.2%].Conclusion Quantitative parameters of spectral CT in the arterial phase can predict the PD-L1 expression of gastric adenocarcinoma,which may provide a reference for the screening and immunotherapy evaluation of patients with gastric adenocarcinoma.
