Objective To evaluate the safety and efficacy of splenectomy with distal pancreatectomy during cytoreductive surgery in epithelial ovarian cancer(EOC).Methods A total of 17 patients from Zhongshan Hospital,Fudan University and the First Affiliated Hospital of University of Science and Technology of China(Anhui Provincial Hospital)received splenectomy with distal pancreatectomy during cytoreductive surgery in EOC were recruited.Their clinicopathological characteristics,postoperative complications and survival situation were retrospective analyzed.Results Of the 17 patients,there were 13 primary cases and 4 recurrent cases.Eleven cases(64.7%)had preoperative imaging finding with metastatic lesions in the splenic hilum,among whom 6 cases had distal pancreas metastasis during the operation.The drainage was placed in the splenic fossa for the measurement of amylase levels in drain fluid and was removed after 8(3-12)days.There were 4 patients had postoperative pancreatic fistula(POPF)of grade A,3 patients had POPF of grade B and no POPF of grade C occurred.The 2 patients with POPF of grade B improved after percutaneous drainage,and the rest recovered with somatostatin,antibiotic drugs and medicines without perioperative mortality.The interval between surgery to chemotherapy was 17.5(13-37)days.The median follow-up time was 14(4-64)months and the median progression-free survival was 10(5-32)months.Conclusion Splenectomy with distal pancreatectomy as part of cytoreduction surgery in EOC is needed for optimal resection,and the complication of pancreatic fistula could be managed conservatively.

Objective To investigate deep neuromuscular blockade(NMD)and moderate NMD on hepatic perfusion and liver function during laparoscopic hepatectomy.Methods A total of 60 patients who received laparoscopic hepatectomy in Fudan University Shanghai Cancer Center were recruited from Dec 2021 to Dec 2022.They were randomly divided into two groups:deep NMD group(D group,n=30)and moderate NMD group(M group,n=30).D group was induced by administration of rocuronium 0.9 mg/kg followed by continuous infusion to maintain intraoperative post-tetanic count(PTC)of 1-2,while M group was induced by administration of rocuronium 0.6 mg/kg followed by continuous infusion to maintain intraoperative train-of-four(TOF)of 1-2.Indocyanine green(ICG)of 0.25 mg/kg was given intravenously both after induction and after specimen excision,and retention rate at fifteen minutes(ICGR15)was recorded.In addition,intraoperative rocuronium dosage,surgical operation satisfaction score,postoperative shoulder pain,and the occurrence of vomiting on postoperative day 1(POD1)were also recorded.Results Compared with M group,the dosage of rocuronium in D group was significantly increased(P<0.01),but there was no difference of ICGR15 between the two groups(P=0.581),even other parameters of perioperative liver function.The surgical operation satisfaction score was significantly higher(P<0.05),while the postoperative shoulder pain(P=0.037,OR=1.37,95%CI:1.01-1.86)and the occurrence of vomiting on POD1(P=0.017,OR=1.64,95%CI:1.07-2.53)were significantly lower in D group than those in M group.Conclusion Compared with moderate NMB,deep NMB can significantly improve surgery condition,reduce postoperative shoulder pain and vomiting.However,there was no significant difference between them on the hepatic perfusion and perioperative liver function.

Objective To evaluate the patient-reported outcome(PRO)of patients with breast cancer who underwent autologous breast reconstruction and implant breast reconstruction.Methods Patients who underwent breast reconstruction in Shanghai Cancer Center,Fudan University from Jan 2020 to Jun 2021 were selected,including 111 patients who underwent autologous breast reconstruction and 108 patients who underwent implant breast reconstruction.Chinese version Breast-Q2.0 scale,breast cancer specificity scale QLQ-BR23 and EORTC quality of life scale QLQ-C30 were used to investigate the PRO of the two groups 18 months after operation.Results The rate of stage Ⅲ breast cancer in the self-weight construction group was higher than that in the implant reconstruction group(64.9%vs.44.4%,P<0.001).The preoperative neoadjuvant therapy and postoperative radiotherapy in the autologous reconstruction group were higher than those in the implant reconstruction group(P<0.001).Postoperative chemotherapy and endocrine therapy in the autologous reconstruction group were lower than those in the implant reconstruction group(P<0.001).The study based on Breast-Q scale showed that the breast satisfaction of autologous reconstruction group was higher than that of implant reconstruction(59.28±17.20 vs.54.94±14.48,P<0.05).The study based on QLQ-BR23 showed that the self-weight construction group was higher than the implant reconstruction group in the field of arm symptoms(20.02±20.80 vs.12.65±16.18,P<0.05).The study based on QLQ-C30 scale showed that there was no significant difference in all functional areas and symptom areas of patients.There was no significant difference in the number and time of social regression between the two groups.Conclusion Breast reconstruction can improve the PRO of breast cancer patients,and oncology factors will affect the choice of breast reconstruction.Patients with autologous breast reconstruction are more satisfied with breast appearance,but upper limb symptoms such as swelling and pain are more obvious than implant reconstruction,which is related to the higher proportion of axillary lymph node dissection in patients with autologous reconstruction.There is no significant difference in quality of life and social regression between the two groups.

At present,the development of enhanced recovery after surgery(ERAS)pathways in deep inferior epigastric perforator(DIEP)flap breast reconstruction is still in the initial stage worldwide,lacking established guidelines.In the multidisciplinary ERAS pathways,the department of anesthesiology is responsible for some core elements such as optimizing anestheticprotocols,perioperative fluid management and homeostasis regulation,prevention of hypothermia,improvement of perioperative analgesia,and postoperative nausea and vomiting prophylaxis.We summarized the anesthetic management in the ERAS pathways for patients undergoing DIEP flap breast reconstruction in Fudan University Shanghai Cancer Center,along with the recent progress,aiming to establish and improve the perioperative strategy based on ERAS pathways in DIEP flap breast reconstruction.

Objective To explore the operation effect of the improved full-appointment mode of ambulatory chemotherapy,so as to provide reference for further improving the treatment process.Methods The enhanced full-appointment mode had been implemented in Fudan University Shanghai Cancer Center outpatient information system,which seamlessly integrated daytime chemotherapy assessment with comprehensive information management,formulated precise rules for chemotherapy appointments,and ensured efficient integration of relevant data.A comparative analysis was conducted between the period after optimization(Jan to Sep 2022)and the corresponding period in the previous year(Jan to Sep 2021),considering factors such as patient waiting time,human involvement,patient safety during chemotherapy,as well as nurse and patient satisfaction.Results After optimization,the time spent by patients was reduced from 52.12(32.73-83.05)to 20.04(11.87-41.10)minutes,with statistically significant difference(z=-78.144,P＜0.001).Additionally,the time spent by patients before and after optimization was significantly different in the distribution of＜30 minutes,30-60 minutes,and＞60 minutes(χ2=5 958.455,P＜0.001).Previously,one nurse and 2-3 security personnel were required to schedule appointments in the daytime chemotherapy center,while after optimization,there was no longer a need for nurses to arrange appointment windows and the number of security personnel was reduced to one,thereby optimized human operations.It was observed that the number of cases involving chemotherapy infusion reactions decreased from 59 to 46 following optimization,and the number of patients requiring rescue observation reduced from four to one.Notably,no rescue events occurred during non-day shifts,thus enhanced patient safety during treatment hours outside regular working hours.Furthermore,there was a statistically significant improvement in both nurses'and patients'satisfaction levels before and after implementation of these optimizations(P＜0.05).Conclusion The modified full appointment mode reduced patient waiting time,optimized human resources utilization,enhanced patient safety during chemotherapy,and improved satisfaction levels among both nurses and patients.The implementation of the modified full appointment mode for daytime chemotherapy centers was beneficial to their overall operation.

Objective Under the background of building age-friendly hospitals,it aims to explore the satisfaction and influencing factors of elderly patients in Shanghai City,which has the highest degree of aging in China,in order to provide reference for improving the age-friendly hospitals.Methods According to the framework of building age-friendly hospitals,a survey questionnaire is designed around friendly services and friendly environment,and the Likert 5-level rating is used.Select one medical institution in the central urban area and one in the suburbs of Shanghai City,both of which are grade-A tertiary age-friendly hospitals,and outpatient patients were randomly selected to participate in the questionnaire survey.A total of 2 418 elderly patients(≥60 years old),were ultimately surveyed.Results Elderly patients'overall satisfaction with medical care,with an average score of 4.77,is very satisfactory;the ratings of friendly service and friendly environment are very good,but relatively speaking,the friendly service is better and the friendly environment is weaker.Among elderly patients,younger(60～74 years old),male,and those living in other places have higher satisfaction.Friendly service and friendly environment are both influencing factors of satisfaction,with friendly service having a greater impact weight.Conclusion Good friendly service should be maintained,and weak friendly environment should be strengthened.Continuously improve age-friendly hospitals and enhance the medical experience of elderly patients.

Objective:To explore the classification and influencing factors of family resilience and post-traumatic growth in patients with spinal tumor.Methods:A cross-sectional investigation was conducted among 219 inpatients with spinal tumor admitted from July 2021 to July 2022. The General Demographic Information questionnaire, Chinese-Family Resilience Assessment Scale, Posttraumatic Growth Inventory, Family Crisis-Oriented Personal Evaluation Scales (F-COPES), and Social Support Rating Scale (SSRS) were used in the study. The ordinal and multivariate logistic regression analyses was applied to identify the factors associated with the classification of family resilience and post-traumatic growth.Results:Of the 219 patients, there were 62 cases of primary spinal tumors (28.3%). According to the results of latent profile analysis, the respondents were classified into three categories by family resilience and post-traumatic growth, namely family difficulty-resistant type ( n=38, 17.4%), general resilience-struggle type ( n=99, 45.2%) and family adaptation-growth type ( n=82, 37.4%). There were significant differences in occupational status, commitment to housework, family atmosphere( χ2=10.75, P=0.025; χ2=6.95, P=0.031; χ2=11.37, P=0.017), and total score of F-COPES and SSRS ( F=25.95, P<0.001; F=19.06, P<0.001)among three groups. Ordinal and multivariate logisitc regression analyses showed that retirement ( OR=2.928, 95% CI:1.098-7.808, P<0.05), family coping ( OR=1.113, 95% CI:1.063-1.165, P<0.05), and social support ( OR=1.226, 95% CI:1.103-1.362, P<0.05) were independently associated with family resilience and post-traumatic growth in patients with spinal tumor. Conclusion:Patients with spinal tumor have significant differences in characteristics by family resilience and post-traumatic growth. As a result, more targeted interventions should be provided for different categories of spinal tumor patients in the future.

Objective To establish the method of simultaneous determination of four main components of Danggui Liuhuang Decoction,including phellodendrine,palmatine,calycosin,and ferulic acid and provide reference for the quality control of Danggui Liuhuang Decoction.Methods Based on the HPLC-MS/MS analysis method,the positive ion data acquisition mode were adopted for the mass spectrometry detection and the four main components were quantified with multiple reaction monitoring mode(MRM)by ESI source.The chromatographic column was Agilent Extend-C18(5 μm,4.6 mm×250 mm),and gradient elution was performed with methanol and 0.5%formic acid in water.Results The linear range of phellodendrine was from 2-200 nmol/ml,and the linear range of palmatine,calycosin and ferulic acid was from 20-2 000 nmol/ml.The contents of the four components in the seven batches of Danggui Liuhuang Decoction were relatively stable,among which ferulic acid was mainly found in Phellodendrine and Coptidis;Phellodendrine was only detected in cortex phellodendri;the content of calycosin in Scutellaria baicalensis and Astragalus was higher;palmatine was detected in both Phellodendron and Astragalus.Conclusion The method had high sensitivity,good specificity and sample stability,which could meet the requirements of quantitative analysis of Traditional Chinese Medicine compounds,and could provide reference for further pharmacokinetics study on the content changes of traditional Chinese medicine compounds in biological samples.

Objective To prepare a novel photosensitive nanoparticle and to evaluate its physicochemical properties,and effect on the efficacy of photodynamic therapy.Methods 5,15-dibromo-10,20-diphenylporphine(DBN),tetrafluoroterephthalonitrile(TFN),and the amphiphilic polymer methoxy-polyethylene glycol-distearoylphosphatidylethanolamine(DSPE-MPEG2000,PEG)were dissolved in tetrahydrofuran(THF)by co-precipitation method to prepare novel photosensitive nanoparticles,named DBN/TFN@PEG.The physicochemical properties of DBN/TFN@PEG were characterized.Both novel and conventional nanoparticles were continuously irradiated with a 660 nm laser,and the fluorescence intensity of nanoparticles,representing reactive oxygen species(ROS)production levels,was measured using a fluorescence spectrophotometer at different irradiation times.Tumor cells were co-incubated with the nanoparticles and irradiated with a 660 nm laser.ROS levels within the tumor cells were detected using immunofluorescence,and the ratio of dead to live tumor cells was determined using PI/Calcein-AM staining.Results Prepared DBN/TFN@PEG nanoparticles with hydrated particle size of approximately 107.8 nm were uniformly distributed in the solution.Compared to conventional nanoparticles,the ROS production capacity of DBN/TFN@PEG was significantly higher(P＜0.01).Immunofluorescence results showed that the generation of ROS levels in the tumor cells of DBN/TFN@PEG group were significantly higher than in the conventional nanoparticles group under laser irradiation(P＜0.01).PI/Calcein-AM staining results indicated a significantly higher ratio of dead tumor cells in the DBN/TFN@PEG group compared to the conventional nanoparticle group(P＜0.01).Conclusions DBN/TFN@PEG has stable physicochemical properties and uniform distribution in the solution.As effective photosensitizers,DBN/TFN@PEG can exhibit stronger ability to induce ROS generation in tumor cells,and may enhance the efficacy of photodynamic therapy in cancer.

Objective:To investigate the clinicopathological features, immunophenotype, diagnosis and differential diagnosis of SRF-rearranged cellular perivascular myoid tumor.Methods:Two cases of SRF-rearranged cellular perivascular myoid tumor diagnosed in the Department of Pathology, Fudan University Shanghai Cancer Center from October 2021 to March 2022 were collected. Immunohistochemical staining, fluorescence in-situ hybridization (FISH) and next-generation sequencing (NGS) were performed, and the literature was reviewed.Results:Case 1, a 3-month-old boy presented with a painless tumor of the scalp, measuring about 2 cm in diameter. Case 2, a 3-year-old girl complained with a painless tumor of the knee, measuring approximately 1.5 cm in diameter. Microscopically, the tumor had a clear boundary and showed multinodular growth. The tumor was mainly composed of spindle cells arranged in long intersecting fascicles associated with thin, slit-like or branching ectatic vessels, focally forming hemangiopericytoma-like appearance. The tumor cells were abundant, but there was no obvious atypia. Mitotic figures (3-4/10 HPF) were noted. H-caldesmon and SMA were positive in both cases. Case 1 showed diffuse and strong positivity for Desmin, and focally for CKpan. Ki-67 proliferation index was 20% and 30%, respectively. FISH displayed NCOA2 gene translocation in case 1 and the RELA gene translocation in case 2. NGS detected the SRF-NCOA2 gene fusion in case 1 and the SRF-RELA gene fusion in case 2. Both patients underwent local excisions. During the follow-up of 5-14 months, case 1 had no local recurrence, while case 2 developed local recurrence 1 year post operatively.Conclusions:SRF-rearranged cellular perivascular myoid tumor is a novel variant of perivascular cell tumor, which tends to occur in children and adolescents. The tumor forms a broad morphologic spectrum ranging from a pericytic pattern to a myoid pattern, and include hybrid tumors with a mixture of pericytic and myoid patterns. Due to its diffuse hypercellularity and increased mitotic figures and smooth muscle-like immunophenotype, the tumor is easy to be misdiagnosed as myogenic sarcomas. The tumor usually pursues a benign clinical course and rare cases may locally recur.
