This study investigated the effect of Wuling San on transforming growth factor-β1(TGF-β1)-induced fibrosis, inflammation, and oxidative stress in human renal tubular epithelial cells(HK-2) and its mechanism of antioxidant stress injury. HK-2 cells were cultured in vitro and divided into a control group, a TGF-β1 model group, and three treatment groups receiving Wuling San-containing serum at low(2.5%), medium(5.0%), and high(10.0%) doses. TGF-β1 was used to establish the model in all groups except the control group. CCK-8 was used to analyze the effect of different concentrations of Wuling San on the activity of HK-2 cells with or without TGF-β1 stimulation. The expression of key fibrosis molecules, including actin alpha 2(Acta2), collagen type Ⅰ alpha 1 chain(Col1α1), collagen type Ⅲ alpha 1 chain(Col3α1), TIMP metallopeptidase inhibitor 1(Timp1), and fibronectin 1(Fn1), was detected using qPCR. The expression levels of inflammatory cytokines, including tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6), interleukin-8(IL-8), and interleukin-4(IL-4), were measured using ELISA kits. Glutathione peroxidase(GSH-Px), malondialdehyde(MDA), catalase(CAT), and superoxide dismutase(SOD) biochemical kits were used to analyze the effect of Wuling San on TGF-β1-induced oxidative stress injury in HK-2 cells, and the expression of nuclear factor E2-related factor 2(Nrf2), heme oxygenase 1(HO-1), and NAD(P)H quinone oxidoreductase 1(NQO1) was analyzed by qPCR and immunofluorescence. The CCK-8 results indicated that the optimal administration concentrations of Wuling San were 2.5%, 5.0%, and 10.0%. Compared with the control group, the TGF-β1 model group showed significantly increased levels of key fibrosis molecules(Acta2, Col1α1, Col3α1, Timp1, and Fn1) and inflammatory cytokines(TNF-α, IL-1β, IL-6, IL-8, and IL-4). In contrast, the Wuling San administration groups were able to dose-dependently inhibit the expression levels of key fibrosis molecules and inflammatory cytokines compared with the TGF-β1 model group. Wuling San significantly increased the activities of GSH-Px, CAT, and SOD enzymes in TGF-β1-stimulated HK-2 cells and significantly inhibited the level of MDA. Furthermore, compared with the control group, the TGF-β1 model group exhibited a significant reduction in the expression of Nrf2, HO-1, and NQO1 genes and proteins. After Wuling San intervention, the expression of Nrf2, HO-1, and NQO1 genes and proteins was significantly increased. Correlation analysis showed that antioxidant stress enzymes(GSH-Px, CAT, and SOD) and Nrf2 signaling were significantly negatively correlated with key fibrosis molecules and inflammatory cytokines in the TGF-β1-stimulated HK-2 cell model. In conclusion, Wuling San can inhibit TGF-β1-induced fibrosis in HK-2 cells by activating the Nrf2 signaling pathway, improving oxidative stress injury, and reducing inflammation.

The differences in chemical quality characteristics between Xinjiang Rehmannia glutinosa and R. glutinosa were analyzed to provide a theoretical basis for the introduction and quality control of R. glutinosa. In this study, the high performance liquid chromatography(HPLC) fingerprints of 6 batches of Xinjiang R. glutinosa and 10 batches of R. glutinosa samples were established. The content of iridoid glycosides, phenylethanoid glycosides, monosaccharides, oligosaccharides, and polysaccharides in Xinjiang R. glutinosa and R. glutinosa was determined by high performance liquid chromatography-diode array detection(HPLC-DAD), high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD), and ultraviolet-visible spectroscopy(UV-Vis). The determination results were analyzed with by chemical pattern recognition and entropy weight TOPSIS method. The results showed that there were 19 common peaks in the HPLC fingerprints of the 16 batches of R. glutinosa, and catalpol, aucubin, rehmannioside D, rehmannioside A, hydroxytyrosol, leonuride, salidroside, cistanoside A, and verbascoside were identified. Hierarchical cluster analysis(HCA) and principal component analysis(PCA) showed that Qinyang R. glutinosa, Mengzhou R. glutinosa, and Xinjiang R. glutinosa were grouped into three different categories, and eight common components causing the chemical quality difference between Xinjiang R. glutinosa and R. glutinosa in Mengzhou and Qinyang of Henan province were screened out by orthogonal partial least squares discriminant analysis(OPLS-DA). The results of content determination showed that there were glucose, sucrose, raffinose, stachyose, polysaccharides, and nine glycosides in Xinjiang R. glutinosa and R. glutinosa samples, and the content of catalpol, rehmannioside A, leonuride, cistanoside A, verbascoside, sucrose, and glucose was significantly different between Xinjiang R. glutinosa and R. glutinosa. The analysis with entropy weight TOPSIS method showed that the comprehensive quality of R. glutinosa in Mengzhou and Qinyang of Henan province was better than that of Xinjiang R. glutinosa. In conclusion, the types of main chemical components of R. glutinosa and Xinjiang R. glutinosa were the same, but their content was different. The chemical quality of R. glutinosa was better than Xinjiang R. glutinosa, and other components in R. glutinosa from two producing areas and their effects need further study.

OBJECTIVES: To study the impact of family socioeconomic status on children's reading fluency and the chain mediation effect of family reading environment and children's living and learning styles in this relationship. METHODS: A total of 473 children from grades 2 to 6 in two primary schools in Nanjing were selected through stratified random sampling. The children's reading fluency was assessed, and a questionnaire was used to collect information on family socioeconomic status, family reading environment, and children's living and learning styles. The mediation model was established using the Process macro in SPSS, and the Bootstrap method was employed to test the significance of the mediation effects. RESULTS: Family socioeconomic status, family reading environment, and children's living and learning styles were significantly positively correlated with reading fluency (P<0.001). The family reading environment and children's living and learning styles mediated the relationship between family socioeconomic status and children's reading fluency. Specifically, the independent mediation effect of family reading environment accounted for 11.02% of the total effect, while the independent mediation effect of children's living and learning styles accounted for 10.79%. The chain mediation effect of family reading environment and children's living and learning styles accounted for 7.41% of the total effect. CONCLUSIONS Family socioeconomic status can affect children's reading fluency through three pathways: family reading environment, children's living and learning styles, and the chain mediation effect of family reading environment and children's living and learning styles.

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

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.

Patient 1,a 12-day-old female infant,presented with fever,cough,dyspnea,and elevated infection markers,requiring respiratory support.Metagenomic next-generation sequencing(mNGS)of blood and bronchoalveolar lavage fluid revealed Legionella pneumophila(LP),leading to diagnoses of LP pneumonia and LP sepsis.The patient was treated with erythromycin for 15 days and azithromycin for 5 days,resulting in recovery and discharge.Patient 2,an 11-day-old female infant,presented with dyspnea,fever,elevated infection markers,and multiple organ dysfunction,requiring mechanical ventilation.mNGS of blood and cerebrospinal fluid indicated LP,leading to diagnoses of LP pneumonia,LP sepsis,and LP intracranial infection.The patient was treated with erythromycin for 19 days and was discharged after recovery.Neonatal LP pneumonia lacks specific clinical symptoms,and azithromycin is the preferred antimicrobial agent.The use of mNGS can provide early and definitive diagnosis for severe neonatal pneumonia of unknown origin.

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.
