ObjectiveTo explore the driving forces for oncology nurses’ participation in palliative care work， thereby providing a theoretical basis for the improvement of education and training， incentive mechanisms， and other aspects of the palliative care nursing staff. MethodsEmploying a qualitative research method， semi-structured interviews lasting 40-60 minutes were conducted with 14 nurses who had participated in palliative care work. The interview data were analyzed using the Colaizzi seven-step analysis method. ResultsInternal positive driving forces were job interest， empathy， and a sense of professional responsibility， while the negative was low psychological resilience. External positive driving forces included high work support， professional identity， mutual benefits for nurses and patients， and positive patient attitudes， whereas negative driving forces comprised busy routine clinical work， lack of a reward and incentive system， and bland or negative patient attitudes. ConclusionIt is essential to provide a flexible platform for the enhancement of nurses’ professional capabilities in palliative care， intensify the publicity of palliative care and death education； intervene and guide nurses’ negative emotions， improve and implement relevant incentive systems， and standardize the job recognition and scope of responsibilities of palliative care nurses.

Objective To Explore the effect of expression of peroxidase reductase 4(PRDX4)on cervi-cal lymph node metastasis in oral squamous cell carcinomas(OSCC)and its relationship with prognosis.Methods Using bioinformatics databases to explore the expression,prognosis analysis,and related pathway prediction of PRDX4 gene in head and neck squamous cell carcinoma.At the same time,clinical and pathologi-cal data including cervical lymph node metastasis were collected from 124 OSCC patients,the expression of PRDX4 was detected in 124 OSCC tissues using immunohistochemical experimental methods.Results Analy-sis of online bioinformatics databases showed that PRDX4 was highly expressed in head and neck squamous cell carcinoma and significantly correlated with tumor grade.The immunohistochemical results showed that the occurrence of cervical lymph node metastasis was significantly correlated with the intensity of PRDX4 stai-ning in 124 OSCC cases studied,and high expression of PRDX4 was an independent risk factor for cervical lymph node metastasis in OSCC(P=0.010).The staining intensity of PRDX4 was significantly correlated with the presence of multiple lymph node metastasis(P=0.020)and the the maximum diameter of lymph node metastasis(P=0.031),but not related to the invasion of lymph nodes outside the membrane.Survival a-nalysis showed that strong PRDX4 positivity was significantly correlated with poor disease-free survival(DFS)rate and overall survival(OS)rate in OSCC patients.Conclusion OSCC patients with strong expres-sion of PRDX4 have a higher incidence of cervical lymph node metastasis and a poorer prognosis.

This study aims to comprehensively evaluate the analytical performance and clinical application value of an acridinium ester-based chemiluminescence assay for detecting heparin-binding protein (HBP), providing more accurate laboratory evidence for the early diagnosis of infections and sepsis. The analytical performance of the HBP detection kit based on acridinium ester chemiluminescence was verified in Hangzhou Hospital of Traditional Chinese Medicine in January 2024 to June 2024, including limit of blank (LoB), accuracy, precision, linear range, anti-interference ability, and clinical diagnostic concordance. The potential of this assay in early diagnosis and treatment monitoring of sepsis was assessed. HBP levels were measured in 97 patients with sepsis and 160 healthy controls, and intergroup differences were analyzed using the Mann-Whitney U test. The results showed that the LoB of the HBP detection kit based on acridinium ester chemiluminescence was 0.10 RLU, and low-concentration sample testing showed good discrimination. In the accuracy evaluation, the regression equation between the test reagent and the comparator was y=1.015 2 x-2.850 8 (R2=0.995 1). For precision, the CV in intra-assay was ≤3.51%, and the CV in inter-assay was ≤4.18%. Within the linear range of 0.42-493.46 ng/ml, the regression equation was y=0.996 9 x+3.066 0 (R2=0.999 1). In interference experiments, the relative deviation was <3%. Clinically, the median HBP concentration in the sepsis group (median: 121.1 ng/ml) was significantly higher than in the control group (median: 6.3 ng/ml, P<0.000 1), with a diagnostic sensitivity of 98.97% and specificity of 96.25%. Age stratification had no effect on HBP levels ( U=448 ,P=0.780 0). In conclusion,the acridinium ester-based chemiluminescence assay requires only about 10 minutes to complete the detection and deliver results, demonstrating acceptable sensitivity, precision, and anti-interference capability. Its wide linear range and rapid detection meet emergency testing needs. Clinical validation confirms HBP′s extremely high sensitivity and specificity for sepsis diagnosis, supporting its role as a key marker for early diagnosis, treatment monitoring, and prognosis assessment.

Objective:To evaluate the clinical outcomes of patients with paroxysmal sympathetic hyperactivity (PSH) after moderate to severe brain injury.Methods:Clinical data describing 580 patients of the Rehabilitation Center of Fuxing Hospital with moderate to severe brain injury were analyzed retrospectively. They were divided into a PSH group and a non-PSH group depending on whether PSH attacks occurred. Propensity score matching was performed to create a 1∶1 ratio between the two groups. The patients′ baseline characteristics were analyzed before the matching and with the matched cohorts, and the clinical outcomes of the patients in the matched cohorts were compared.Results:Seventy-five of the patients experienced PSH attacks and were included in the PSH group, while the others formed the non-PSH group. Before matching, the two groups had significant differences in age, atrial fibrillation, hypertension, chest trauma, Glasgow Coma Scale (GCS) score, tracheotomy, hydrocephalus, heart rate at admission, respiration rate, muscle tone, and limited joint activity. After the propensity score matching, 67 patients were included in the PSH and non-PSH groups. The differences in heart rate, respiration rate, muscle tone, and limited joint activity between the two groups at admission were then statistically significant. However, unlike the non-PSH group, the PSH group showed a significant decrease in its average GCS score and Glasgow Outcome Scale (GOS) score at discharge, as well as a significant increase in its average Disability Rating Scale score. Compared with the non-PSH group at the same time point, the GOS score of the PSH group had decreased by 0.47 at discharge ( CI: 0.41-0.56). Then, three months after discharge the average GOS score of the PSH group had decreased by 0.55 ( CI: 0.48-0.61. By six months that was 0.75 ( CI: 0.66-0.82) and by twelve months 0.87 ( CI: 0.77-0.97). Conclusions:PSH can affect the consciousness of patients with moderate to severe brain injury and their ability in the activities of daily life. The prognosis of PSH patients is relatively poor.

Objective:To investigate the effect of PD-1/PD-L1 inhibitor BMS-1 on LPS-induced inflammation in mouse microg-lia cells(BV-2 cells).Methods:Bv-2 cells were divided into Control group,LPS group and LPS+BMS-1 group.Bv-2 cells in Control group were cultured in DMEM medium for 78 hours,cells in LPS group were stimulated with 100 ng/ml LPS for 6 hours after 72 hours of normal culture,Bv-2 cells in LPS+BMS-1 group were treated with 50 nmol/ml BMS-1 for 72 hours and then stimulated with 100 ng/ml LPS for 6 hours.Expressions of PD-1 and iNOS mRNA in each group were detected by RT-qPCR,and expressions of PD-1 and iNOS protein in microglia were detected by Western blot.Flow cytometry was used to detect cell apoptosis in each group.Levels of inflamma-tory cytokines IL-1β,IL-6,TNF-α and IL-10 were detected by ELISA.Results:RT-qPCR and Western blot results showed that com-pared with Control group,LPS group had significantly increased expression of PD-1 and iNOS(P<0.05).Compared with LPS group,LPS+BMS-1 group had significantly decreased expression of PD-1(P<0.05)and significantly increased expression of iNOS(P<0.05).Flow cytometry showed that compared with Control group,LPS group had a significantly increased in apoptosis of microglia(P<0.000 1).Compared with LPS group,LPS+BMS-1 group had a significantly increased in apoptosis of microglia(P<0.000 1).ELISA results showed that compared with Control group,LPS group had no significantly increased in pro-inflammatory factors IL-1β and IL-6(P>0.05),while significantly increased in TNF-α(P<0.000 1)and anti-inflammatory factor IL-10(P<0.000 1).Pro-inflammatory cyto-kine IL-1β in LPS+BMS-1 group was significantly higher than that in LPS group(P=0.000 1),IL-6 and TNF-α were also significantly higher than those in LPS group(P<0.000 1),while anti-inflammatory cytokine IL-10 in LPS+BMS-1 group was significantly lower than that in LPS group(P<0.000 1).Conclusion:BMS-1 can promote LPS-induced inflammatory response or impede the recovery of inflammation,and increase apoptosis of microglia.PD-1/PD-L1 pathway may be a potential therapeutic target for neuroinflammation.

Objective To examine resting-state whole-brain network connectivity in children with Chinese developmental dyslexia(DD)and typically developing(TD)children using functional near-infrared spectroscopy(fNIRS).Methods From November to December,2024,19 DD children aged six to twelve years in Children's Hospital of Fudan University were enrolled,along with 18 TD children matching age and sex.Regions of interest included frontal cortex(FC),temporal lobe(TL),occipital lobe(OL)and parietal lobe(PL).Resting-state data were acquired by fNIRS for five minutes in both groups.Functional connectivity strength was calculated at rest,and between-group differences in connectivity strength and brain networks were compared,based on the time series of oxyhe-moglobin concentration.Results The whole-brain functional connectivity strength was higher in DD group than in TD group(t=2.100,P<0.05).Connectivity between the right OL-right FC(t=2.426,P<0.05),right OL-left FC(t=2.483,P<0.05),right TL-right FC(t=2.568,P<0.05)and right TL-left FC(t=2.304,P<0.05)were stonger in DD group than in TD group.The major regions exhibiting differences of whole-brain connectivity between two groups were the right dorsolateral prefrontal cortex,right visual association cortex,right frontal cortex,left orbitofrontal cortex,left visual association cortex,left primary visual cortex and right primary motor cortex.Conclusion Children with DD exhibited significantly stronger connectivity in the right occipital and temporal lobes,as well as between these regions and the prefrontal cortex,suggesting possible right-hemispheric compensation for insufficiency in the left-hemisphere reading network.

Objective:To evaluate the feasibility and safety of open ventilation masks in patients with proliferative diabetic retinopathy (PDR) undergoing vitrectomy under local anesthesia.Methods:A randomized clinical trial was conducted.Eighty PDR patients (80 eyes) undergoing vitrectomy with local anesthesia were enrolled at Xuzhou Municipal Hospital from May to July 2024.Patients were randomly divided into an experimental group and a control group using a random number table method, with 40 cases (40 eyes) in each group.The experimental group received oxygen through an ophthalmic surgical open ventilation mask during the operation, while the control group used a traditional nasal cannula.The respiratory rate, heart rate, systolic blood pressure, diastolic blood pressure, and oxygen saturation before and after oxygen inhalation during the operation were compared between the two groups.Patient comfort level, airway patency, anxiety status, satisfaction level, operation time, surgical success rate, and incidence of intraoperative complications were also compared.This study adhered to the Declaration of Helsinki and the study protocol was appreed by the Ethics Committee of Xuzhou Municipal Hospital (No.2024-KY-065).Results:After oxygen inhalation during the operation, improvements in respiratory rate, heart rate, and oxygen saturation were greater in the experimental group than in the control group, with statistically significant differences ( t=4.671, 7.894, 1.588; all P<0.05).The Borg, and Hamilton Anxiety Scale scores were lower in the experimental group than in the control group, with statistically significant differences ( t=2.828, 4.880; both P<0.05), while the Bruggrmann Comfort Scale score was higher than that in the control group ( t=2.774, P<0.05).There were no statistically significant differences in operation time, surgical success rate or incidence of complications between the two groups ( t=0.595, P=0.554; χ2=0.346, 0.263; both P>0.05).Satisfaction rate of patients in the experimental group was 97.5%(39/40), which was higher than 85.0%(34/40) in the control group, with a statistically significant difference ( χ2=3.914, P=0.048). Conclusions:For PDR patients undergoing vitreous surgery under local anesthesia, using an ophthalmic surgical open ventilation mask for oxygen inhalation can effectively enhance respiratory comfort level, alleviate anxiety, maintain stable vital signs, improve overall comfort level, and ensure smooth surgery, without observed adverse reactions related to mask use, which makes it worthy of clinical promotion and application.

Objective To investigate the impact of integrated healthcare team-implemented en-hanced recovery after surgery(ERAS)protocol combined with nutritional support on rehabilitation outcomes of patients with femoral neck fracture undergoing total hip arthroplasty.Methods A total of 100 patients with femoral neck fracture scheduled for total hip arthroplasty were enrolled and ran-domly divided into observation group and control group,with 50 patients in each group.The observa-tion group received rehabilitation nursing approach integrating ERAS by an integrated healthcare team along with nutritional support,while the control group received conventional treatment and rehabilita-tion nursing.Results The observation group demonstrated a significantly shorter time to first ambu-lation and postoperative length of hospital stay,as well as lower hospitalization costs compared with the control group(P＜0.05).At discharge,the observation group had higher scores on the Mini-nu-tritional Assessment(MNA)and elevated serum indicator values compared with the control group(P＜0.05).Additionally,the observation group achieved higher hip joint scores,a lower total complica-tion rate,and greater body weight compared with the control group(P＜0.05).Conclusion The implementation of ERAS by integrated healthcare team combined with nutritional support can effec-tively promote the rehabilitation of patients with femoral neck fracture undergoing total hip arthroplas-ty,yielding favorable rehabilitation outcomes.

Objective To explore the risk factors for postoperative atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCAB) alone. Methods A retrospective analysis was conducted on the clinical data of patients who underwent OPCAB in the Department of Cardiac Surgery Ward No.1 of Zhengzhou Seventh People’s Hospital from January 2020 to January 2024. Patients were categorized into a POAF group and a non-POAF group based on the occurrence of POAF. The clinical data of both groups were analyzed. Parameters underwent univariate analysis, and variables with P≤0.05 in univariate analysis were further analyzed through binary multivariate logistic regression to identify independent risk factors. Results A total of 496 patients were included. There were 312 males and 184 females, with age ranging from 50 to 78 years. There were 148 patients in the POAF group and 348 patients in the non-POAF group. The incidence of POAF after isolated OPCAB surgery was 29.8%. Results of univariate analysis showed that there were statistical differences in the incidence of diabetes (P=0.012), >75% stenosis of the left circumflex artery (LCX) (P=0.036), shock (P<0.001), graded left ventricular diastolic function (P<0.001), left ventricular ejection fraction (P<0.001), age (P<0.001), preoperative resting heart rate (P<0.001), left atrial diameter (P<0.001), E/A ratio (P<0.001), postoperative K+ concentration (P<0.001), and postoperative Mg2+ concentration (P<0.001). Binary multivariate logistic regression analysis revealed that age (OR=1.436, 95%CI 1.094 to 1.884, P=0.009), diabetes (OR=2.032, 95%CI 1.006 to 4.145, P=0.043), preoperative resting heart rate (OR=1.008, 95%CI 1.001 to 1.015, P=0.018), left atrial diameter (OR=4.409, 95%CI 1.711 to 11.359, P=0.002), and E/A ratio (OR=1.713, 95%CI 1.115 to 2.633, P=0.014) were independent risk factors for POAF after isolated OPCAB. The occurrence of POAF significantly prolonged mechanical ventilation time and ICU stay (both P＜0.001). Conclusion Age, diabetes, left atrial diameter, E/A ratio, and preoperative resting heart rate are potential independent risk factors for POAF following OPCAB surgery. Additionally, the occurrence of POAF can lead to prolonged mechanical ventilation and extended stay in the intensive care unit.

Objective To analyze the correlation between the duration of hyperbaric oxygen(HBO)therapy and oral medication clonazepam reduction in patients with paroxysmal sympathetic hyperactivity(PSH).Methods Clinical data of patients with secondary PSH after severe brain injury at Capital Medical University Affiliated Fuxing Hospital from September 2017 to July 2023 were retrospectively included,covering general information,etiology,lesion location,comorbidities,vital signs at admission,PSH attack characteristics,HBO treatment frequency,PSH treatment drugs and dosage.According to the number of HBO treatments,PSHpatients were divided into HBO short course group(10 treatments)and HBO long course group(＞10 treatments).Multiple logistic regression and rank correlation analysis were used to investigate the correla-tion between the duration/frequency of HBO treatment and the reduction of clonazepam.Results A total of 75 PSH patients who met the inclusion and exclusion criteria were selected,including 38 cases(50.7％)who re-ceived reduced doses of clonazepam.There were 32 cases(42.7％)in the HBO short course group and 43 ca-ses(52.3％)in the HBO long course group.The reduction rate of clonazepam in the HBO short course group was lower than that in the HBO long course group[31.3％(10/32)vs.65.1％(28/43),crude OR=4.11(95％CI:1.55-10.90),P=0.004].After adjusting for confounding variables,a multivariate Logistic re-gression model showed a significant correlation between HBO long course and clonazepam reduction(OR=3.76,95％CI:1.23-11.55,P=0.021).Rank correlation analysis showed a positive correlation between HBO treatment frequency and clonazepam reduction(rs=0.331,P=0.004).Conclusions Long course HBO treatment was positively correlated with oral reduction of clonazepam in PSH patients,which may help re-duce the side effects caused by clonazepam and become a non-pharmacological treatment option for PSH.
