Objective:To analyze the current situation and core issues of medical escort services in Shanghai through a two-side (supply and demand) survey, so as to provide references for formulating targeted strategies for the standardized management of this industry.Methods:From June to August 2024, a questionnaire survey on awareness of escort services was conducted among patients at 16 tertiary public hospitals in Shanghai. The survey covered patients′ basic information, their needs, concerns, and expectations regarding escort services. Concurrently, a specialized questionnaire was administered to trainees enrolled in Shanghai Open University′s " elderly care escort service provider" program. This survey covered the companions′ basic profiles, types of service recipients, relevant qualifications, training programs, and standardized service procedures. Data were organized and analyzed by using SPSS 26.0 software.Results:The survey on awareness of patient escort services yielded 855 valid responses, achieving a 92.13% response rate. Among these 855 patients, the primary demand for escort services was queue management for examinations (515 cases, 71.47%), followed by assistance with registration/payment/medication pickup (528 cases, 61.74%). 587 patients (68.66%) expressed willingness to use the service. The main concerns included lack of professional expertise among attendants (538 cases, 62.92%), trust issues (494 cases, 57.78%), and fee concerns (456 cases, 53.33%). Expectations for service supervision primarily focused on service quality and safety (618 cases, 72.28%) and pricing standards (609 cases, 71.23%). The specialized survey on medical escort services yielded 194 valid questionnaires, achieving a 100.00% response rate. Among the 194 medical escort service providers, 82.5% (160 individuals) were full-time practitioners, 31.96% (62 individuals) held relevant qualification certificates, and 72.68% (144 individuals) had participated in related training programs. Regarding standardized services, 74.74% (145 individuals) of medical escorts obtained patient information prior to service delivery, 56.70% (110 individuals) signed agreements with users, and 67.01% (130 individuals) maintained records of their medical escort services.Conclusions:Shanghai′s medical escort services had achieved some success, yet faced challenges including high patient demand coupled with low trust, insufficient certification and training for escorts, and an urgent need to improve service standardization. It is recommended that medical institutions further strengthen their primary role in managing escort services. By enhancing top-level design, establishing standardized training and certification mechanisms, implementing comprehensive quality monitoring and credit evaluation systems, and other measures, they could elevate the professional competence of practitioners, reinforce patient safety safeguards, and promote the high-quality, standardized development of escort services.

Objective To develop a tool for assessing the needs for care services for adults with disabilities in welfare institutions,and formulate criteria for classifying care needs.Methods Based on the theory of the International Classification of Functioning,Disability and Health,the core contents of domestic and international care service assessment standards were analysed,and the first draft of the assess-ment tool was formed integrating with the current practice of welfare institutions.A total of eleven experts in the field of care services validated the first draft,and the assessment tool was revised according to the experts'opin-ions.From May to June,2024,340 adults with disabilities from Second Social Welfare Institute of Shanghai were graded to analyze the reliability and validity of the assessment tool.And then,1 046 subjects from Second Social Welfare Institute of Shanghai were graded using the assessment tool,and the scoring intervals for the five levels of care were determined using cluster analysis.Results The assessment tool included four first-level dimensions,eleven second-level dimensions,39 third-level dimen-sions and 43 indicators.The coefficients of variation of each dimension and indicator were less than 0.25 for ex-pert validation,while the average score of the importance of each indicator was above 4.63,with a full score rate more than 0.86.The overall Cronbach's α coefficient was 0.956,the test-retest reliability was 0.997,and the con-tent validity index of each indicator was 0.83 to 1.00.The exploratory factor analysis extracted four common fac-tors,with a cumulative variance contribution of 86.679%;the loading coefficients of indicators were 0.675 to 0.878,and the correlation coefficients among the dimensions were 0.325 to 0.476.Cluster analysis determined the level of institutional care needs as level 1(severe),level 2(medium-heavy),level 3(medium),level 4(light-moderate),and level 5(light).Conclusion The needs assessment tool for care services for adults with disabilities in welfare institutions developed in this study is good in reliability and validity,and can be used in guiding the care services provided for people with disabilities more efficient and targeted.

Background and purpose:For patients with human epidermal growth factor receptor 2(HER2)-positive metastatic breast cancer,trastuzumab treatment can prolong the overall survival and significantly improve the prognosis of patients.However,the reference original research trastuzumab(Herceptin?)is more expensive.Biosimilars have comparable efficacy and safety profiles while increasing patient access to treatment.This clinical trial aimed to evaluate the efficacy,pharmacokinetics,safety and immunogenicity of the trastuzumab biosimilar AK-HER2 compared to trastuzumab(Herceptin?)in patients with HER2-positive metastatic breast cancer.Methods:This multi-center,randomised,double-blind phase Ⅲ clinical trial was conducted in 43 subcenters in China.This study complied with the research protocol,the ethical principles stated in the Declaration of Helsinki and the quality management standards for drug clinical trials.It was approved by the hospital's medical ethics committee.The clinical trial registration agency is the State Food and Drug Administration(clinical trial approval number:2015L04224;clinical trial registration number:CTR20170516).Written informed consent was obtained from subjects before enrollment.Enrolled patients were randomly assigned to the AK-HER2 group and the control group,respectively receiving AK-HER2 or trastuzumab(initial loading dose 8 mg/kg,maintenance dose 6 mg/kg,every 3 weeks as a treatment cycle,total treatment time is 16 cycles)in combination with docetaxel(75 mg/m2,treatment duration is at least 9 cycles).The primary endpoint of this clinical trial was the objective response rate(ORR9)between the AK-HER2 group and the control group in the 9th cycle.Secondary efficacy endpoints included ORR16,disease control rate(DCR),clinical benefit rate(CBR),progression-free survival(PFS)and 1-year survival rate.In this study,100 subjects(AK-HER2 group to control group=1:1)were randomly selected for blood sample collection after the 6th cycle of medication,The collection time points were 45 minutes after infusion(the end of administration),4,8,24,72,120,168,336,and 504 hours after the end of administration.After collection,blood samples were analyzed by PK parameter set(PKPS).Other evaluation parameters included safety and immunogenicity assessment.Results:A total of 550 patients with HER2-positive metastatic breast cancer were enrolled in this clinical trial between Sep.2017 and Mar.2021.In the AK-HER2 group(n=237),129 subjects in the experimental group achieved complete response(CR)or partial response(PR),and the ORR9 was 54.4%.There were 134 subjects in the control group(n=241)who achieved CR or PR,and the ORR9 was 55.6%.The ORR9 ratio between the AK-HER2 group and the control group was 97.9%[90%confidence interval(CI):85.4%-112.2%,P=0.784],which was not statistically significant.In all secondary efficacy endpoints,no statistically significant differences were observed between the two groups.We conducted a mean ratio analysis of pharmacokinetics(PK)parameters between the AK-HER2 group and the control group,and the results suggested that the pharmacokinetic characteristics of the two drugs are similar.The incidence of treatment emergent adverse event(TEAE)leading to drug reduction or suspension during trastuzumab treatment was 3.6%(10 cases)in the AK-HER2 group and 8.1%(22 cases)in the control group.There was statistically significant difference between the two groups(P=0.027).The incidence rate was significantly lower in the AK-HER2 group than in the control group,and there was no statistically significant difference among the other groups.The differences in the positive rates of anti-drug antibodies(ADA)and neutralizing antibodies(NAB)between groups were of no statistical significance(P=0.385 and P=0.752).Conclusion:In patients with HER2-positive metastatic breast cancer,AK-HER2 was comparable to the trastuzumab(Herceptin?)in terms of drug efficacy,pharmacokinetics,safety and immunogenicity.

Background and purpose:BRCA1/2 plays an important role in maintaining the genome stability.Whether BRCA1/2 germline mutation could increase the tumor sensitivity to radiotherapy,thereby inducing secondary primary cancer after radiotherapy is unclear.This study aimed to investigate whether postoperative radiotherapy is a risk factor for the development of second primary cancer in triple-negative breast cancer(TNBC)patients with BRCA1/2 germline mutation.Methods:This research was based on a previously reported retrospective cohort,i.e.,the Fudan University Shanghai Cancer Center TNBC cohort.Between January 1,2007 and December 31,2014,a total of 292 female TNBC patients with BRCA1/2 mutation were enrolled.We performed logistic regression analysis in patients without BRCA1/2 germline mutation(n=261)and BRCA1/2 germline mutation patients(n=31),respectively,to assess the risk factors affecting the incidence of second primary cancer.We then performed interactive analysis on the above two analyses to evaluate the interactive effect between BRCA1/2 germline mutation and postoperative radiotherapy.P<0.05 indicates a statistically significant difference.The research was approved by Fudan University Shanghai Cancer Center TNBC Ethics Committee(050432-4-2108),and each patient provided written informed consent.Results:Logistic regression analysis in patients with BRCA1/2 germline mutations showed that postoperative radiotherapy significantly increased the risk of secondary primary disease compared to non-radiotherapy[odds ratio(OR)=2.475,95%confidence interval(CI):1.933-3.167,P<0.001].In patients without BRCA1/2 germline mutation,the effect of radiotherapy on the incidence of second primary tumor was not significant.There was a significant interaction between BRCA1/2 germline mutation and postoperative radiotherapy for the incidence of secondary primary cancer(OR=9.710,95%CI:0.320-295.250,P=0.193).Conclusion:Although statistical analysis results show that patients with BRCA1/2 germline mutations have an increased risk of developing a second primary tumor after postoperative radiotherapy compared to patients who have not received radiotherapy,there is no significant correlation between BRCA1/2 germline mutations and radiotherapy for the development of a second primary tumor.Therefore,patients with BRCA1/2 germline mutations who receive radiotherapy after surgery may not increase the risk of developing a second primary tumor.

Objective:To investigate the regulatory effect of transient receptor potential cation channel subfamily C member 3 (TRPC3) on the retina in oxygen-induced retinopathy (OIR) mice and biological behavior of human retinal vascular endothelial cells (HREC).Methods:A total of 32 healthy SPF grade 7-day-old C57BL/6 mice were selected and randomly divided into a control group and an OIR group by the random number table method, with 16 mice in each group.The control group received no special treatment, and the OIR model was established in the OIR group.On postnatal day 17 (PN17), the success of the model establishment was verified by immunofluorescence staining of the retinal patch.The in vitro cultured HREC were divided into a normal control group, a transfection reagent group, and a si-TRPC3 group.The normal control group received no special treatment, while the transfection reagent group and the si-TRPC3 group were transfected with transfection reagent or transfection reagent + si-TRPC3.The relative expression of TRPC3 mRNA was detected by real-time quantitative fluorescence PCR.The relative expressions of TRPC3, transcription factor NF-E2 related factor (Nrf2), and superoxide dismutase (SOD) proteins were determined by Western blot.HREC were further divided into a normal control group, a vascular endothelial growth factor (VEGF) group, a si-TRPC3 group, and a Pyr3 (TRPC3 channel inhibitor) group, which were cultured in complete medium, medium containing 20 ng/ml VEGF recombinant protein, medium containing 20 ng/ml VEGF recombinant protein (si-TRPC3 transfection for 72 hours), and medium containing 20 ng/ml VEGF recombinant protein+ 1 μmol/L Pyr3 for 48 hours, respectively.The proliferation ability of HREC was detected using cell counting kit 8 (CCK-8). The horizontal and vertical migration ability of cells were detected by cell scratch assay and transwell assay, respectively.This study followed the 3R principles of animal welfare and was approved by the Ethics Committee of Hebei Eye Hospital (No.2023LW04). Results:Pathological neovascular clusters with strong fluorescent staining appeared in the retina of OIR mice on PN17.The relative expressions of TRPC3 mRNA and protein in the retina of OIR mice were 2.057±0.244 and 1.517±0.290, respectively, significantly higher than 0.983±0.033 and 0.874±0.052 of control group ( t=6.165, 3.094; both at P<0.05). The relative expression levels of TRPC3 mRNA and protein were significantly lower, and the relative expression levels of Nrf2 and SOD proteins were higher in the si-TRPC3 group than in the normal control and transfection reagent groups, and the differences were statistically significant (all at P<0.05). The CCK-8 experiment results showed that the cell absorbance value was higher in the VEGF group than in the normal control group, and lower in the si-TRPC3 and Pyr3 groups than in the VEGF group, with statistically significant differences (all at P<0.05). The results of the cell scratch experiment showed that the lateral migration rate of VEGF group cells was higher than that of normal control group, while the lateral migration rate of si-TRPC3 group and Pyr3 group cells was lower than that of VEGF group, and the differences were statistically significant (all at P<0.05). The transwell experiment results showed that the number of stained cells in the VEGF group was higher than that in the normal control group, and the number of stained cells in the si-TRPC3 group and Pyr3 group was lower than that in the VEGF group, with statistically significant differences (all at P<0.05). Conclusions:Hypoxia induces increased TRPC3 expression in OIR mouse retina, and downregulation of TRPC3 inhibits HREC proliferation and migration.The mechanism is related to the activation of the Nrf2-related oxidative stress pathway.
