Objective:To explore the effects of an intervention strategy based on dyadic illness management theory on dyadic coping level, supportive care needs, and patients' disease symptoms with chemotherapy-stage ovarian cancer patients and their spouses, and to provide reference for improving their disease coping ability and quality of life.Methods:This study used the method of randomized controlled trial. Seventy pairs of ovarian cancer patients and their spouses who received regular chemotherapy and their spouses from Obstetrics and Gynecology Hospital, Fudan University from July 2022 to June 2023 were selected using convenience sampling method. They were assigned to the control group (36 pairs) and the observation group (36 pairs) by the random number table method. Participants in the control group received routine nursing care and the observation group received the intervention strategy of dyadic illness management theory. Data were collected and compared the differences in dyadic coping levels, care needs, and disease symptoms between two groups of patients and their spouses before intervention (before chemotherapy) and after intervention (after the end of the chemotherapy cycle). SPSS 20.0 software was used for analysis, and t-tests, χ2 tests, and Wilcoxon rank sum tests were used to compare the two groups. Results:Finally, 36 pairs were included in the control group and 34 pairs in the observation group. The age of the control group patients was (52.03 ± 9.44) years old, while that of the observation group patients was (53.41 ± 10.14) years old. After the intervention, the total score of dyadic coping level in the patients and their spouses of the observation group were (113.50 ± 8.03), (114.62 ± 10.59) points, respectively, which were higher than (106.64 ± 10.06), (108.78 ± 10.89) points of the control group with significant differences ( t=-3.14, -2.27, both P<0.05); the total score of care needs in the patients and their spouses of the observation group were (89.65 ± 8.29), (95.12 ± 7.25) points, respectively, which were lower than (100.25 ± 10.82), (110.11 ± 7.58) points of the control group with significant differences ( t=4.58, 8.45, both P<0.001); the total score of disease symptoms in the patients of the observation group was (20.09 ± 4.70) points, which was lower than (31.53 ± 6.08) points of the control group with significant differences ( t=8.77, P<0.001). Conclusions:The model of dyadic illness management can improve dyadic coping level and supportive care needs of chemotherapy-stage ovarian cancer patients and their spouses, and alleviate patients′ disease symptoms.

Objective:To explore the different reaction patterns among family caregivers of patients with advanced gynecological malignancies, and to analyze the influencing factors of different profiles.Methods:A cross-sectional study was conducted with 210 family caregivers of patients with advanced gynecological malignancies from Obstetrics and Gynecology Hospital in Shanghai from January 2022 to December 2022. Data were collected by Caregiver Reaction Assessment, Mishel's Uncertainty in Illness Scale-Family Member Form and Perceived Social Support Scale. Latent profile analysis was used to explore the different reaction patterns among family caregivers of patients with advanced gynecological malignancies. The influencing factors of caregiver reaction were identified by multivariate Logistic regression.Results:Totally 208 questionnaires were effectively collected. The family caregivers among patients with advanced gynecological malignancies included 163 males and 45 females, aged (53.89 ± 12.61) years old. The reaction characteristics of 208 family caregivers among patients with advanced gynecological malignancies were divided into three categories: low burden and high benefit group (24.5%, 51/208), moderate burden and benefit group (30.8%, 64/208), and high burden and low benefit group (44.7%, 93/208). Compared to the low burden and high benefit group, caregivers with lower levels of social support were more likely to be classified as moderate burden and benefit group, high burden and low benefit group ( OR = 0.563, 0.407, both P<0.01). Caregivers with moderate burden and benefit group, high burden and low benefit group had higher levels of disease uncertainty ( OR = 1.328, 2.064, both P<0.01). The caregiver′s age, monthly family income, education level, and co-caregivers were also influencing factors regarding to care reaction among family caregivers of patients with advanced gynecological malignancies ( OR values were 0.207-6.422, all P<0.05). Conclusions:The care reaction of family caregivers among patients with advanced gynecological malignancies has obvious categorical features. Healthcare professionals should implement targeted nursing interventions according to their reaction characteristics, so as to reduce the care burden of family caregivers and improve the quality of care for patients with advanced gynecological malignancies.

Objective: To investigate the molecular mechanism and identify potential drugs for subthreshold depression (SD), and elucidate the detalied mechanism of Danzhi Xiaoyao powder (DZXY) in SD. Methods: Using RNA-sequencing, we identified differentially expressed genes (DEGs) in leukocytes of SD compared to healthy controls, deciphered their functions and pathways, and identified the hub genes of SD. We also assessed changes in leukocyte transcription factor activity in patients with SD using the TELiS platform. The Connectivity Map database was retrieved to screen candidate drugs for SD. Based on network pharmacology, we elucidated the “multi-component, multi-target, and multi-pathway” mechanism of DZXY in the treatment of SD. Results: We identified 1080 DEGs (padj <0.05 and |log2 (fold change)| ≥ 1 & protein coding) in the leukocytes of patients with SD. These DEGs, including hub genes, were primarily involved in immune and inflammatory response-related processes. Transcription factor activity analysis revealed similarities between the leukocyte transcriptome profile in SD and the conserved transcriptional response to adversities in immune cells. Connectivity Map analysis identified 28 potential drugs for SD treatment, particularly SB-202190 and TWS-119. Constructing the “Direct Compounds-Direct Targets-Pathways” network for DZXY and SD revealed the curative mechanisms of DZXY in SD, primarily including inflammatory response, lipid metabolism, immune response, and other processes. Conclusion These results provide new insights into the characteristics and functional changes of leukocytes in SD, partially illustrate the pathogenesis of SD, and suggest potential drugs for SD. The curative mechanisms of DZXY in SD are also partially elucidated.

Objective To develop a nurse-led case management practice program for ovarian cancer patients,and to investigate its application effect initially.Methods The case management practice model of ovarian cancer was formed through literature analysis,qualitative research and expert meeting method.Ovarian cancer patients who were given conventional nursing interventions from Aug 2022 to Jun 2023 and from Jul 2023 to Mar 2024 in Obstetrics and Gynecology Hospital,Fudan University were selected as the control group(n=16)and the intervention group(n=16).The patients'supportive care needs,disease symptoms and unplanned readmission rates were compared before and after intervention between two groups.Supportive Care Needs Survey Shortform 34(SCNS-SF34)was used to collect patients'supportive care needs,and M.D.Anderson Symptom Inventory(MDASI)was used to assess disease symptoms.Results The ovarian cancer case management practice program was constructed and revised to determine the qualification and professional competence of the ovarian cancer case manager,the core of practice,and the specific implementation pathway.After intervention,the total score and scores of all dimensions of SCNS-SF34 in the intervention group were lower than those of the control group(P<0.001),the total score and scores of all dimensions of MDASI in the intervention group were lower than those of the control group(P<0.05).There was no statistically significant difference in unplanned readmission rates between the two groups.Conclusion The case management practice program for ovarian cancer patients was constructed with scientific validity,which can effectively meet the care needs of patients and alleviate their disease symptoms.

With the development of genetics and advances in genetic testing technology,the demand for cancer genetic counseling has increased dramatically.Advanced practice nurses play a key role in personalized health care delivery.The oncology genetic nurse-led genetic counseling services in foreign countries are becoming more and more mature,but in China,the work of oncology genetic counseling started late,and the combination of genetics/genomics with nursing is still in its infancy.There is still a lack of relevant research on oncology genetic nurses.This article introduced the qualification certification,core competence and clinical practice content of foreign oncology genetic nurses,and summarized the clinical practice effect of oncology genetic nurses and the enlightenment to China's advanced nursing practice,which provided references for the construction of oncology genetic nurses training programs and clinical service models suitable for China's national conditions,so as to meet the needs of the development of advanced nursing practice and the growing demand for precision oncology and high-quality genetic medical care.

Insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) is a recognition protein for N⁶-methyladenosine (m⁶A), mediating the stability of downstream mRNA, and is a promising anti-tumor target. Based on the lead compound 1g from previous screening, this study designed and synthesized 52 IGF2BP2 small molecule inhibitors using thiazole hydrazone as the parent nucleus. Among them, 9g, 10g, 37g, 47g and 52g showed good inhibitory activities. This work represents an initial exploration in the development of small molecule inhibitors targeting IGF2BP2, using thiazolehydrazone as the core structure. It lays a foundation for subsequent related research.

Vitamins,as important micronutrients widely involved in human physiological functions,play a significant role in parenteral nutrition therapy due to their inability to be synthesized or insufficient synthesis in the body,requiring exogenous supplementation. However,a consensus does not exist in China regarding the dosage and monitoring of vitamins in parenteral nutrition. Experts in the field are recruited by Chinese Nutrition Society for Medical Food and Nutrition Support,Chinese Society for Parenteral and Enteral Nutrition (CSPEN),Shanghai Medical Association for Parenteral and Enteral Nutrition and the Shanghai Nutrition Society to formulate a consensus paper.The current paper aims to provide standardized guidance for clinical use of vitamins in parenteral nutrition. The consensus paper is a composite of systematically reviewing pertinent literature,Chinese clinical practice and multiple sessions of debate,discussion,and composition,with reference to guidelines from European Society for Parenteral and Enteral Nutrition (ESPEN),American Society for Parenteral and Enteral Nutrition (ASPEN),Australasian Society for Parenteral and Enteral Nutrition (AuSPEN) and CSPEN.This includes 37 recommendations regarding the recommended dosage and monitoring of fat-soluble vitamins (vitamins A,D,E,K) and water-soluble vitamins (vitamin C and vitamins B1,B2,B6,B12,niacin,pantothenic acid,biotin,and folate) to serve varied adult parenteral nutrition patients.

Objective:To explore the characteristics of the immunophenotypic expression of bone marrow monocytes (M ) and its clinical significance in patients with multiple myeloma (MM ). Methods:The monocyte immunophenotypes expression of 67 MM and 30 anemic patients (control group)were detected by flow cytometry.The immunophenotypes that exhibited statistical differences from the control group were screened out.Further univariate and multivariate regression was used analyze the risk factors affecting the prognosis. The effect of monocyte immunophenotype on the prognosis of MM was analyzed.The correlation of CD38+monocytes with clinical features was explored.Results:The percentages of CD138+monocytes (CD138+M％),CD27+monocytes (CD27+M％),and CD56+monocytes (CD56+M％)in the MM group were significantly higher than that in the control group(P<0.05),but the percentages of CD38+monocytes (CD38+M％)and HLA-DR+monocytes (HLA-DR+M％)were significantly lower than that in the control group (P<0.01 ).The median progression-free survival (PFS)was shorter in the low CD38+monocyte proportion (LCD38+M％)group compared to the high CD38+monocyte proportion (HCD38+M％) group.Additionally,the median overall survival (OS)was significantly shorter in the low CD138+monocyte proportion (LCD138+M％),low CD27+monocyte proportion (LCD27+M％),low CD38+monocyte proportion (LCD38+M％),and low HLA-DR+monocyte proportion (LHLA-DR+M％)groups.Cox regression analysis showed that the low CD38+M％ was an independent risk factor for OS.The LCD38+M％group had significantly higher proportions of involved/uninvolved free light chain ratios ≥100 and 1q21+compared to the HCD38+M％ group (P<0.05 ). Moreover,the proportion of CD38-myeloma cells was significantly higher in the LCD38+M％ group than that in the HCD38+M％ group (P<0.05).Conclusion:The expression of CD38+monocytes in bone marrow of MM patients is closely related to the prognosis and clinical characteristics.CD38+monocytes maybe used to predict prognosis and guide treatment decisions.

Objectives: To investigate the current application status and implementation difficulties of extracorporeal cardiopulmonary resuscitation (ECPR) in children with sudden cardiac arrest. Methods: This cross-sectional survey was conducted in 35 hospitals. A Children's ECPR Information Questionnaire on the implementation status of ECPR technology (abbreviated as the questionnaire) was designed, to collect the data of 385 children treated with ECPR in the 35 hospitals. The survey extracted the information about development of ECPR, the maintenance of extracorporeal membrane oxygenation (ECMO) machine, the indication of ECPR, and the difficulties of implementation in China. These ECPR patients were grouped based on their age, the hospital location and level, to compare the survival rates after weaning and discharge. The statistical analysis used Chi-square test and one-way analysis of variance for the comparison between the groups, LSD method for post hoc testing, and Bonferroni method for pairwise comparison. Results: Of the 385 ECPR cases, 224 were males and 161 females. There were 185 (48.1%) survival cases after weaning and 157 (40.8%) after discharge. There were 324 children (84.2%) receiving ECPR for cardiac disease and 27 children (7.0%) for respiratory failure. The primary cause of death in ECPR patients was circulatory failure (82 cases, 35.9%), followed by brain failure (80 cases, 35.0%). The most common place of ECPR was intensive care unit (ICU) (278 cases, 72.2%); ECPR catheters were mostly inserted through incision (327 cases, 84.9%). There were 32 hospitals (91.4%) had established ECMO emergency teams, holding 125 ECMO machines in total. ECMO machines mainly located in ICU (89 pieces, 71.2%), and the majority of hospitals (32 units, 91.4%) did not have pre-charged loops. There were no statistically significant differences in the post-withdrawal and post-discharge survival rates of ECPR patients among different age groups, regions, and hospitals (all P>0.05). The top 5 difficulties in implementing ECPR in non-ICU environments were lack of ECMO machines (16 times), difficulty in placing CPR pipes (15 times), long time intervals between CPR and ECMO transfer (13 times), lack of conventional backup ECMO loops (10 times), and inability of ECMO emergency teams to quickly arrive at the site (5 times). Conclusion: ECPR has been gradually developed in the field of pediatric critical care in China, and needs to be further standardized. ECPR in non-ICU environment remains a challenge.
