Objective:To investigate the effects of ubiquitin-specific protease (USP) 7/47 inhibitor (Cat. No. 1247825-37-1) on the proliferation and apoptosis of acute myeloid leukemia (AML) cells with or without internal tandem duplications of the Flt3 gene (Flt3-ITD). Methods:ATP assay was used to detect the effects of 1247825-37-1 on the cell viability of two AML cell lines (MOLM13 and MV4-11) harboring Flt3-ITD mutation and one AML cell line (THP-1) without Flt3-ITD mutation as well as the primary Flt3-ITD-mutant and non-mutant AML cells from patient samples. Flow cytometry was used to detect the apoptosis of AML cell lines treated by different concentrations of 1247825-37-1.Results:Compared with the control group, 1247825-37-1 was able to significantly inhibit the proliferation of MOLM13, MV4-11 and THP-1 cells ( P<0.000 1). Besides, the cell viability of primary AML cells was also inhibited by 1247825-37-1, and a stronger inhibitory effect on non-mutant AML cells was observed. The USP7/USP47 inhibitor 1247825-37-1 could inhibit the proliferation of AML cells in a dose-dependent manner and a low dose (2 or 4 μmol/L) of 1247825-37-1 would be effective. Moreover, 1247825-37-1 was also able to efficiently induce the apoptosis of above AML cell lines in a dose-dependent manner.

Effects of breastfeeding on immune response of CD4+T lymphocytes in infants / 中国儿童保健杂志

【Objective】 To explore the effects of breastfeeding on the immune response of CD4+T lymphocytes in infants in non-inflammatory state, and to analyze the immunomodulatory significance of the whole composition of breast milk. 【Methods】 A retrospective cohort study was conducted. From January to September 2022, six-month-old infants who took physical examination in the Child Healthcare Department of Changzhou Children′s Hospital Affiliated to Nantong University, were selected based on inclusion criteria, and were divided into breastfeeding group (n=33) and formula feeding group (n=27) based on their feeding patterns. Flow cytometry was used to detect the percentage of CD4+ T cells, including helper T cell (Th) 1, Th2, Th17, regulatory T cell (Treg), and the levels of related cytokines interleukin (IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-17 in peripheral blood. The differences in these indicators between the two groups were compared. 【Results】 Compared with the formula feeding group, the breastfeeding group showed significantly higher percentages of Th1(t=3.038), Treg (t=2.088). The ratio of Th1 to Th2(Z=2.756), IL-10(Z=2.297) and IFN-γ (Z=2.076) in the peripheral blood of the breastfeeding group were also significantly higher. Conversely, the breastfeeding group had significantly lower percentage of Th17(Z=2.704) and IL-17A (t=2.187) (P<0.05). There was no significant difference the percentage of Th2, as well as in the levels of IL-2, IL-4, IL-6 and TNF-α between the two groups (P>0.05). 【Conclusions】 Breastfeeding has a regulatory effect on the immune response of infant CD4+ T lymphocytes. It promotes the development of Th1/Th2 towards Th1 and the immunomodulatory effect of Treg. Moreover, it inhibits the Th17 type immune response. These findings suggest that the complete composition of breast milk contributes to the development and maturation of infant immune system, enhancing immune defense and immune tolerance.

Effect Mechanism of Modified Baitouwengtang Treating Colorectal Cancer by Regulating CSF1R/STING/TBK1 Signaling to Polarize Phenotype of Tumor-associated Macrophages （TAMs） / 中国实验方剂学杂志

ObjectiveThis study aims to investigate the effect of modified Baitouwengtang （MBTWD） on tumor growth and the number of tumor-associated macrophages （TAMs） in tumor tissue of MC38 cell tumor-bearing mice with colorectal cancer and explores whether MBTWD mediates the remodeling of TAM phenotype to play an immunologically antitumor effect. MethodFirstly， The C57BL/6 mouse tumor model grafted subcutaneously was established， and then model mice were classified into a model group， positive control group（3 mg·kg-1）， and MBTWD groups with high and low dosages（23.43、46.86 g·kg-1）， with 10 mice in each group. In addition， 10 healthy mice were set as the blank group， and the changes in body weight， tumor volume， and survival status of mice in each group were observed. Tumor tissue， spleen， and peripheral blood were collected to calculate the tumor volume change， tumor inhibition rate， and spleen mass. Hematoxylin-eosin （HE） staining was used to observe the morphological changes of tumor tissue， and an immunofluorescence assay was used to detect the expression levels of CD4， CD8， and CD206 in tumor tissues of tumor-bearing mice. The secretion levels of transforming growth factor （TGF）-β， interleukin （IL）-6， and chemokine （C-C Motif） ligand 2 （CCL2） in peripheral serum were measured by using enzyme-linked immunosorbent assay （ELISA）. Secondly， a co-culture model induced by IL-4 in vitro of MC38 cells and murine monocytic macrophage RAW264.7 cells was established. Cell proliferation and activity assay （CCK-8） was used to detect the inhibitory effect of MBTWD containing serum on cell proliferation. A transwell experiment was used to detect the effect of IL-4-induced M2 macrophages on the invasion of MC38 cells. Flow cytometry was used to detect the expression of CD86 on the membrane of M2 macrophages induced by IL-4 with MBTWD containing serum. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the effect of MBTWD containing serum on the mRNA expression levels of M1 macrophage-related polarization factors CD86， nitric oxide synthase （iNOS）， and IL-12， as well as M2 macrophage-related polarization factors CD206， CD163， and IL-10 after co-cultivation. Finally， the protein expression levels of colony-stimulating factor 1 receptor （CSF1R）， stimulator of interferon genes （STING）， and TANK binding kinase 1 （TBK1） in tumor tissues of tumor-bearing mice were detected by Western blot. ResultIn vivo experimental results show that compared with the model group， the MBTWD can significantly inhibit the tumor growth of tumor-bearing mice. Immunofluorescence experiments show that the MBTWD can increase the number of CD8+ T cell infiltration in tumor tissue of tumor-bearing mice， reduce the number of CD206+ TAMs infiltration， and down-regulate the secretion levels of cytokines IL-6， TGF-β， and CCL2 in peripheral blood of tumor-bearing mice. The results of in vitro experiments show that the MBTWD containing serum has no obvious inhibitory effect on cell proliferation， but the cell supernatant after co-cultivation with RAW264.7 cells can inhibit the proliferation activity of MC38 cells， and the invasion ability of MC38 cells is enhanced by IL-4-induced M2 macrophages. However， this effect can be inhibited in a concentration-dependent manner by the MBTWD containing serum. At the same time， the results of Real-time PCR show that the MBTWD containing serum can up-regulate the mRNA expression levels of M1 macrophage-related polarization factors CD86， iNOS， and IL-12 and down-regulate those of M2 macrophage-related polarization factors CD206， CD163， and IL-10. Flow cytometry results also confirm that the MBTWD containing serum can increase the number of repolarized CD86+ M1 macrophages， indicating that MBTWD can induce M2 macrophages to repolarized M1 macrophages to play an anti-tumor growth role. Finally， Western blot results show that MBTWD can down-regulate the expression of CSF1R protein and up-regulate that of STING and TBK1 proteins in tumor tissue of tumor-bearing mice. ConclusionMBTWD can down-regulate the infiltration number of CD206+ TAMs and increase the infiltration of CD8+ T cells， thereby playing an immunologically antitumor effect on the growth inhibition of colorectal cancer， which may be related to regulating CSF1R signaling and then activating STING/TBK1 signaling pathway to induce phenotypic remodeling of TAMs.

Cerebral ischemic injury after transcatheter aortic valve replacement in patients with pure aortic regurgitation / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Considering the surgical risk stratification for patients with severe calcific aortic stenosis (AS), transcatheter aortic valve replacement (TAVR) is a reliable alternative to surgical aortic valve replacement (SAVR) (Fan et al., 2020, 2021; Lee et al., 2021). Despite the favorable clinical benefits of TAVR, stroke remains a dreaded perioperative complication (Auffret et al., 2016; Kapadia et al., 2016; Kleiman et al., 2016; Huded et al., 2019). Ischemic overt stroke, identified in 1.4% to 4.3% of patients in TAVR clinical practice, has been associated with prolonged disability and increased mortality (Auffret et al., 2016; Kapadia et al., 2016; Levi et al., 2022). The prevalence of hyperintensity cerebral ischemic lesions detected by diffusion-weighted magnetic resonance imaging (DW-MRI) was reported to be about 80%, which is associated with impaired neurocognitive function and vascular dementia (Vermeer et al., 2003; Barber et al., 2008; Kahlert et al., 2010).

Core in jingjin diagnosis and treatment: yizhi weishu / 中国针灸

Jingjin (muscle region of meridian) is a distal diagnosis and treatment system of the sinew/fascia disorders on the base of the concept of jin in TCM. Jin should be a particular palpable structure rather than a single anatomic structure with a specific distributing course. Yizhi weishu refers to a idea running through the whole process of diagnosis and treatment of sinew/fascia disorders, in which, the results, obtained by the overall observation and palpation of patient's sinew/fascia structure, are taken as the criteria of treatment. Yitong weishu (taking the sites of sensitivity or tenderness as the points) verifies this idea in practice. Under the guidance of yizhi weishu, through identifying the primary from the secondary, and regulating yin and yang, the spasticity and flaccidity of sinews/fascia can be cured and the induced diseases treated. The diagnosis and treatment system of jingjin, based on yizhi weishu, develops the original jingjin theory with vague concept involved, formulates a systematic thinking of treatment for sinew/fascia disorders and provides a new approach to clinical treatment.

Isoliquiritigenin induces HMOX1 and GPX4-mediated ferroptosis in gallbladder cancer cells / 中华医学杂志(英文版)

BACKGROUND@#Gallbladder cancer (GBC) is the most common malignant tumor of biliary tract. Isoliquiritigenin (ISL) is a natural compound with chalcone structure extracted from the roots of licorice and other plants. Relevant studies have shown that ISL has a strong anti-tumor ability in various types of tumors. However, the research of ISL against GBC has not been reported, which needs to be further investigated.@*METHODS@#The effects of ISL against GBC cells in vitro and in vivo were characterized by cytotoxicity test, RNA-sequencing, quantitative real-time polymerase chain reaction, reactive oxygen species (ROS) detection, lipid peroxidation detection, ferrous ion detection, glutathione disulphide/glutathione (GSSG/GSH) detection, lentivirus transfection, nude mice tumorigenesis experiment and immunohistochemistry.@*RESULTS@#ISL significantly inhibited the proliferation of GBC cells in vitro . The results of transcriptome sequencing and bioinformatics analysis showed that ferroptosis was the main pathway of ISL inhibiting the proliferation of GBC, and HMOX1 and GPX4 were the key molecules of ISL-induced ferroptosis. Knockdown of HMOX1 or overexpression of GPX4 can reduce the sensitivity of GBC cells to ISL-induced ferroptosis and significantly restore the viability of GBC cells. Moreover, ISL significantly reversed the iron content, ROS level, lipid peroxidation level and GSSG/GSH ratio of GBC cells. Finally, ISL significantly inhibited the growth of GBC in vivo and regulated the ferroptosis of GBC by mediating HMOX1 and GPX4 .@*CONCLUSION@#ISL induced ferroptosis in GBC mainly by activating p62-Keap1-Nrf2-HMOX1 signaling pathway and down-regulating GPX4 in vitro and in vivo . This evidence may provide a new direction for the treatment of GBC.

Research Progress of Lung Cancer Vaccines / 中国肺癌杂志

With the development of medical technology, tumor vaccines as a novel precise immunotherapy approach have gradually received attention in clinical applications. Against the backdrop of the global corona virus disease 2019 (COVID-19) outbreak, vaccine technology has further advanced. Depending on the types of antigens, tumor vaccines can be divided into whole-cell vaccines, peptide vaccines, messenger ribonucleic acid (mRNA) vaccines, recombinant virus vaccines, etc. Although some tumor vaccines have been marketed and achieved certain therapeutic effects, the results of tumor vaccines in clinical trials have been unsatisfactory in the past period. With the maturation of next-generation sequencing (NGS) technology and the continuous development of bioinformatics, dynamic monitoring of the entire process of tumor subpopulation development has become a reality, which has laid a solid foundation for personalized, neoantigen-centered therapeutic tumor vaccines. This article reviews the recent developments of tumor vaccines of different types, starts with lung cancer and summarizes the achievements of tumor vaccines in clinical applications, and provides an outlook for the future development of antigen-centered tumor vaccines.

Tu-Xian Decoction ameliorates diabetic cognitive impairment by inhibiting DAPK-1 / 中国天然药物

Tu-Xian decoction (TXD), a traditional Chinese medicine (TCM) formula, has been frequently administered to manage diabetic cognitive impairment (DCI). Despite its widespread use, the mechanisms underlying TXD's protective effects on DCI have yet to be fully elucidated. As a significant regulator in neurodegenerative conditions, death-associated protein kinase-1 (DAPK-1) serves as a focus for understanding the action of TXD. This study was designed to whether TXD mediates its beneficial outcomes by inhibiting DAPK-1. To this end, a diabetic model was established using Sprague-Dawley (SD) rats through a high-fat, high-sugar (HFHS) diet regimen, followed by streptozotocin (STZ) injection. The experimental cohort was stratified into six groups: Control, Diabetic, TC-DAPK6, high-dose TXD, medium-dose TXD, and low-dose TXD groups. Following a 12-week treatment period, various assessments-including blood glucose levels, body weight measurements, Morris water maze (MWM) testing for cognitive function, brain magnetic resonance imaging (MRI), and histological analyses using hematoxylin-eosin (H&E), and Nissl staining-were conducted. Protein expression in the hippocampus was quantified through Western blotting analysis. The results revealed that TXD significantly improved spatial learning and memory abilities, and preserved hippocampal structure in diabetic rats. Importantly, TXD administration led to a down-regulation of proteins indicative of neurological damage and suppressed DAPK-1 activity within the hippocampal region. These results underscore TXD's potential in mitigating DCIvia DAPK-1 inhibition, positioning it as a viable therapeutic candidate for addressing this condition. Further investigation into TXD's molecular mechanisms may elucidate new pathways for the treatment of DCI.

Efficacy and safety of various doses of hybutimibe monotherapy or in combination with atorvastatin for primary hypercholesterolemia: a multicenter, randomized, double-blind, double-dummy, parallel-controlled phase Ⅲ clinical trial / 中华心血管病杂志

Objective: To evaluate the efficacy and safety of hybutimibe monotherapy or in combination with atorvastatin in the treatment of primary hypercholesterolemia. Methods: This was a multicenter, randomized, double-blind, double-dummy, parallel-controlled phase Ⅲ clinical trial of patients with untreated primary hypercholesterolemia from 41 centers in China between August 2015 and April 2019. Patients were randomly assigned, at a ratio of 1∶1∶1∶1∶1∶1, to the atorvastatin 10 mg group (group A), hybutimibe 20 mg group (group B), hybutimibe 20 mg plus atorvastatin 10 mg group (group C), hybutimibe 10 mg group (group D), hybutimibe 10 mg plus atorvastatin 10 mg group (group E), and placebo group (group F). After a dietary run-in period for at least 4 weeks, all patients were administered orally once a day according to their groups. The treatment period was 12 weeks after the first dose of the study drug, and efficacy and safety were evaluated at weeks 2, 4, 8, and 12. After the treatment period, patients voluntarily entered the long-term safety evaluation period and continued the assigned treatment (those in group F were randomly assigned to group B or D), with 40 weeks' observation. The primary endpoint was the percent change in low density lipoprotein cholesterol (LDL-C) from baseline at week 12. Secondary endpoints included the percent changes in high density lipoprotein cholesterol (HDL-C), triglyceride (TG), apolipoprotein B (Apo B) at week 12 and changes of the four above-mentioned lipid indicators at weeks 18, 24, 38, and 52. Safety was evaluated during the whole treatment period. Results: Totally, 727 patients were included in the treatment period with a mean age of (55.0±9.3) years old, including 253 males. No statistical differences were observed among the groups in demographics, comorbidities, and baseline blood lipid levels. At week 12, the percent changes in LDL-C were significantly different among groups A to F (all P<0.01). Compared to atorvastatin alone, hybutimibe combined with atorvastatin could further improve LDL-C, TG, and Apo B (all P<0.05). Furthermore, there was no significant difference in percent changes in LDL-C at week 12 between group C and group E (P=0.991 7). During the long-term evaluation period, there were intergroup statistical differences in changes of LDL-C, TG and Apo B at 18, 24, 38, and 52 weeks from baseline among the statins group (group A), hybutimibe group (groups B, D, and F), and combination group (groups C and E) (all P<0.01), with the best effect observed in the combination group. The incidence of adverse events was 64.2% in the statins group, 61.7% in the hybutimibe group, and 71.0% in the combination group during the long-term evaluation period. No treatment-related serious adverse events or adverse events leading to death occurred during the 52-week study period. Conclusions: Hybutimibe combined with atorvastatin showed confirmatory efficacy in patients with untreated primary hypercholesterolemia, which could further enhance the efficacy on the basis of atorvastatin monotherapy, with a good overall safety profile.

Clinical research of Allium urethral stent in the treatment of membranous urethral stricture / 中华泌尿外科杂志

There are few reports on the use of Allium stents in the treatment of membranous urethral stricture in China. Its safety and effectiveness need to be observed. This study retrospectively analyzed the data of 5 patients admitted to our hospital for the treatment of membranous urethral stricture using Allium-covered metal urethral stents in the past 5 years. The preoperative International Prostatic Symptom Score (IPSS) score was 8.80±1.30, quality of life(QOL)score was 4.20 ±0.84, and the International Index of Erectile Function-5(IIEF-5) score was 20.20 ± 1.92, respectively. Six months after the operation, the IPSS score was 3.60±1.52, the QOL score was 1, and the IIEF-5 score was 19.80±1.48. This operation is easy with little invasion. It can alleviate the dysuria of patients with membranous urethral stricture and has little impact on the sexual function of patients. It is generally safe and controllable, but the appropriate time for implantation still needs to be explored.

The clinical characters and prognostic value of flare phenomenon in metastatic castration resistant prostate cancer patients treated with Abiterone / 中华泌尿外科杂志

Objective:To investigate the clinical characters and prognostic value of PSA flare and bone flare in metastatic castration resistant prostate cancer(mCRPC) patients received Abiterone acetate(AA) therapy.Methods:A retrospective study was conducted for 93 mCRPC patients treated with AA from Jul.2016 to Dec.2020. Mean age was (75.4±8.9)years, median PSA was 58.2 (16.4, 148.6)ng/ml. Patients received at least 6 months of AA treatment. PSA flare was defined as an increase of PSA after AA therapy followed by a decrease. Bone flare was defined as disease progression after 3 months of therapy, typically based on increased lesion intensity or number, and reevaluation 6-9 months later showed improvement in the scan. The clinical characters and prognostic value of the flare phenomenon was evaluated and analyzed respectively.Results:The median follow up time was 16 months(6, 54 months), fourteen patients showed PSA flare at first month after AA treatment, and median time of duration was 2 months(1, 7 months). The serum alkaline phosphatase (ALP) had a similar rising trend along with PSA flare[115.5(98.0, 198.5)U/L vs. 119.0(97.0, 288.8)U/L, P=0.016]. Seven patients showed bone flare and 3 cases co-existed with PSA flare. Multivariate Cox regression analysis indicated bone flare was an independent protective factor for progression free survival(PFS)( HR=0.117, 95% CI 0.015-0.895, P=0.039), PSA flare had no significant influence on PFS ( HR=1.314, 95% CI 0.554-3.121, P=0.536)and overall survival(OS)( HR=1.348, 95% CI 0.393-4.263, P=0.635). Log-rank test showed patients with bone flare had a longer PFS( P=0.016) and OS( P=0.047) compared with patients without bone flare. Conclusions:PSA flare always faded away after 2 months AA therapy and had no influence on PFS and OS. Bone flare maybe an indication for better prognosis.

Influencing factors for continuous renal replacement therapy after heart transplantation / 中华器官移植杂志

Objective:To explore the influencing factors of continuous renal replacement therapy(CRRT)after heart transplantation(HT).Methods:For this retrospective cohort study, the relevant clinical data were retrospectively reviewed for 145 recipients undergoing HT at No.7 Municipal People's Hospital from April 2018 to December 2022.They were assigned into two groups of non-CRRT(n=124)and CRRT(n=21). And t, χ2or rank-sum test was utilized for comparing baseline data, intraoperative and postoperative general conditions of two groups.Variables with P<0.05 in univariate analysis and significant indicators in previous studies were included in multivariate logistic regression analysis to analyze the influencing factors of CRRT post-HT.Receiver operating characteristic curve(ROC)was utilized for selecting the optimal predictive cut-off value. Results:Among them, 66 cases(45.52%)developed AKI and 21(14.48%)required CRRT.Through univariate analysis, preoperative estimated glomerular filtration rate(eGFR), erythrocyte count, platelet, hemoglobin, total bilirubin, intraoperative volume of blood loss, volume of blood transfusion, urine volume, operative duration, cardiopulmonary bypass time, postoperative mechanical ventilation time, ICU stay and postoperative acute kidney injury were compared.The inter-group differences were statistically significant( P<0.05). Further multivariate logistic regression analysis revealed that preoperative hemoglobin level( OR=0.869, 95% CI: 0.770-0.980, P=0.022), preoperative platelet count( OR=0.959, 95% CI: 0.925-0.993, P=0.019), intraoperative volume of hemorrhage( OR=1.004, 95% CI: 1.000-1.009, P=0.049), intraoperative urine volume( OR=0.997, 95% CI: 0.993-1.000, P=0.035), operative duration( OR=1.022, 95% CI: 1.000-1.044, P=0.047)and mechanical ventilation time( OR=1.036, 95% CI: 1.005-1.069, P=0.024)were the independent influencing factors of CRRT post-HT.ROC curve results indicated that area under curve(AUC)of operative duration, mechanical ventilation time and intraoperative volume of hemorrhage were 0.745(95% CI: 0.636-0.855), 0.835(95% CI: 0.735-0.934)and 0.669(95% CI: 0.506-0.830)with a sensitivity of 0.714, 0.857, 0.571 and a specificity of 0.710, 0.685, 0.895.And the cut-off values were 283.5 min, 25.46 h and 825 ml respectively. Conclusions:Hemoglobin level, preoperative platelet count, intraoperative volume of hemorrhage, urine volume, operative duration, mechanical ventilation time and intraoperative urine volume are independent influencing factors of CRRT post-HT.Operative duration >283 min, mechanical ventilation time >25.46 h and intraoperative volume of hemorrhage >825 ml have some predictive values for CRRT post-HT.

The clinical characteristics and prognostic value of PSA dynamic features in patients with metastatic castration resistant prostate cancer received abiraterone acetate / 中华泌尿外科杂志

Objective:To analyze the clinical characteristics and prognostic value of prostate-specific antigen (PSA) dynamic features in patients with metastatic castration resistant prostate cancer (mCRPC) received abiraterone acetate (AA) therapy.Methods:The data of 89 patients with mCRPC who received AA therapy from January 2017 to June 2021 in Shanghai Tongji Hospital were retrospectively reviewed. The age of patients was (75.7 ± 8.3) years old, median PSA before AA was 56.88 (19.31, 143.75) ng/ml. The PSA dynamic features included PSA nadir (PSAN) and PSAN time. PSAN was defined as the lowest value of PSA after treatment, and PSAN time was defined as time to PSAN after AA treatment. PSAN was divided into 3 groups: PSAN1 (<0.1 ng/ml), PSAN2 (0.1- 4.0 ng/ml) and PSAN3 (>4.0 ng/ml) groups. PSA response was defined as a maximum PSA decline rate ≥50%, and no PSA decline after treatment was defined as primary resistance. Cox regressions adjusted to clinical factors were performed to evaluate the influence of PSA dynamic features on patients' radiographic progression-free survival (rPFS) and overall survival (OS). Log-rank test was used to evaluate the survival time of patients in different PSAN groups. Receiver operator characteristic (ROC) curve and area under the curve (AUC) were performed to analyze the predictive value of PSA dynamic features on survival outcomes of patients.Results:The follow-up time was 17 (12, 23) months, and 75 (84.3%) patients showed PSA responses. The median PSAN was 1.82 (0.01, 11.70) ng/ml, median PSAN time was 5.0(3.0, 9.5)months. Multivariate Cox regression indicated that PSAN was an independent risk factor for rPFS ( PSAN2: HR=5.308, P=0.017; PSAN3: HR=13.209, P<0.001), and PSAN time ≥ 5 months( HR=0.309, P<0.001)was an independent protective factor for rPFS. Also, the PSAN3 was an independent risk factor for OS( HR=9.459, P=0.048). Log-rank test indicated that the rPFS of PSAN1 group (median not reached) was significantly longer than PSAN2 [median 13.0(95% CI 8.2-17.8) months, P=0.001] and PSAN3 [8.0 (95% CI 4.1-11.9) months, P<0.001] groups. ROC curve and AUC showed that PSAN had a higher predictive value in rPFS outcomes compared with T stage, metastatic disease volume, and Eastern Cooperative Oncology Group (ECOG) score (0.82 vs. 0.69, 0.68, 0.53, P<0.05). PSAN had a higher predictive value in OS outcomes than metastatic disease volume and ECOG(0.83 vs. 0.63, 0.58, P<0.05). Conclusions:Lower PSAN needs longer PSAN time. PSAN is an independent risk factor for rPFS and OS, and PSAN time is an independent protective factor for rPFS.

Investigation on the Current Situation and Influencing Factors of Attitudes and Training Needs of Hospice Care among Nursing Staff in Hainan Province / 中国医学伦理学

【Objective:】 To investigate the current situation of attitudes and training needs of hospice care among nursing staff in Hainan Province, and analyze the influencing factors, so as to provide basis for formulating scientific and standardized hospice care training programs for nursing staff. 【Methods:】 From October to December in 2021, a total of 1 819 nursing staff from 45 general hospitals, specialized hospitals and nursing homes in 14 cities and counties of Hainan province were selected by convenience sampling method to conduct the questionnaire on hospice care attitude and training needs. 【Results:】 1 789 valid questionnaires were collected with effective recovery of 98.35%. Nursing staff hospice care attitude score was (88.13±12.10) points, the standard score was 70.4 points, hospice care attitude was at medium level. Nursing staff training needs score was (26.96±5.16) points, the standard score was 89.87, the needs of each dimension and item were higher than 75.1%, the training needs were at high level. Professional title, currently engaged in hospice care services, and willingness to engage in hospice care services were the influencing factors of hospice care training needs (P<0.05), and the hospital, have witnessed the death of dying patients or relatives, willingness to engage in hospice care services were the main influencing factors of nurses’ attitude toward hospice care (P<0.05). 【Conclusion:】 At present, nursing staff in Hainan Province held a moderate attitude towards hospice care, and had a high demand for training. The major obstacles for nursing staff to engage in hospice care at present were high stress in the face of dying patients and symptom management. Nursing managers should combine the current situation, pay attention to stimulate nurses’ intrinsic motivation, strengthen the training of nursing staff’s concept of hospice nursing, construct a diversified training system, and carry out specialized and modular skill practice and theoretical training to improve nursing staff’s hospice care ability.
