ObjectiveTo explore the effect of cluster scalp acupuncture combined with Taijiquan training on depressive symptom, motor function, activities of daily living, serum markers, as well as brain functional connectivity (FC) and network topological properties in patients with post-stroke depression (PSD). MethodsA total of 40 PSD patients in the Second Affiliated Hospital of Heilongjiang University of Chinese Medicine from September, 2022 to September, 2023 were enrolled and randomly divided into control group (n = 20) and experimental group (n = 20). The control group received cluster scalp acupuncture alone, while the experimental group underwent Taijiquan training in addition, for four weeks. They were assessed with Hamilton Depression Scale-17 (HAMD-17), Fugl-Meyer Assessment (FMA) and Barthel Index (BI) before and after treatment, while the serum levels of dopamine (DA), 5-hydroxytryptamine (5-HT), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected with enzyme-linked immunosorbent assay. Resting-state functional magnetic resonance imaging (rs-fMRI) was applied to assess brain FC, as well as the global efficiency (Eg) and small-world property (σ) of brain networks. ResultsThe scores of HAMD-17, FMA and BI improved in both groups (t > 2.922, P < 0.01) after treatment, and improved more in the experimental group than in the control group (t > 2.517, P < 0.05). The serum levels of DA and 5-HT increased in both groups (t > 2.637, P < 0.05), and increased more in the experimental group (t > 2.192, P < 0.05). The serum levels of IL-6 and TNF-α decreased in the experimental group after treatment (t > 4.059, P < 0.001), and they were less than those in the control group (t > 2.154, P < 0.05). FC between left middle frontal gyrus and right anterior cingulate gyrus, as well as between left hippocampus and right precuneus were higher in the experimental group than in the control group after treatment (t > 3.867, P < 0.001), while Eg and σ increased in both groups (t > 2.828, P < 0.05), and they were higher in the experimental group (t > 2.675, P < 0.05). ConclusionCombination of Taijiquan training is more effective on depressive symptoms, motor function and activities of daily living in PSD patients, which may be related to up-regulation of serum DA and 5-HT, reduction of inflammatory factors, enhancement of prefrontal-limbic system functional connectivity and optimization of brain network topological properties.

Purpose To evaluate the value of tumors invasion in the central airway(TICA)in predicting the severe immune checkpoint inhibitor-related pneumonitis(S-CIP)in lung cancer patients using propensity score matching(PSM).Materials and Methods The intact data of 162 consecutive lung cancer patients who received treatment with immune checkpoint inhibitors in Xi'an International Medical Center Hospital from September 2019 to March 2022 were retrospectively collected.Patients were divided into S-CIP group(23 cases)and non-S-CIP group(139 cases)according to the presence of S-CIP.The demographic information of the patients,including gender,age,history of smoking,thoracic radiotherapy histology,baseline lung diseases,classification,TNM stage,tumor location as well as TICA were collected.A binary Logistic regression was used to analyze the confounding factors and independent risk factors of S-CIP and to predict the development of S-CIP.A 1:1 matching was performed by the nearest neighbor method for PSM.The PSM was used to pair the two groups,and the value of TICA in predicting S-CIP before and after PSM was compared.The receiver operating characteristic curve and the area under the curve were used for model performance based on TICA.Results Before PSM,the proportion of baseline lung diseases(78.3%vs.32.4%,OR=6.802,P=0.001),thoracic radiotherapy history(69.6%vs.30.2%,OR=5.300,P=0.002)and TICA(65.2%vs.27.3%,OR=5.882,P=0.001)in the S-CIP group was higher than those in the non-S-CIP group,and were independent risk factor for predicting S-CIP.After PSM,20 patients were included in each group.The presence of TICA was higher in S-CIP group than that in the non-S-CIP group(60.0%vs.20.0%,OR=6.000,P=0.013).The area under the curves of Logistic regression model based on TICA was 0.700(95%CI 0.534-0.866).Conclusion TICA is an independent risk factor for development of S-CIP,which has moderate degree of accuracy in predicting S-CIP,can be used for risk prediction and early intervention to reduce the poor prognosis of S-CIP patients.

Objective To construct a visual imaging decision model for evaluating the prognosis of hepatocellular carcinoma(HCC)patients treated with interventional therapy based on MRI features.Methods A total of 130 HCC patients were selected.All of them underwent MRI examination upon admission,and then the interventional therapy was implemented after clinical evaluation.The patients were followed up for 2 years after the last interventional therapy,and then were divided into poor prognosis group(50 cases)and good prognosis group(80 cases)according to the follow-up results.The risk factors affecting the poor prognosis of HCC patients treated with interventional therapy were screened.A nomogram model was constructed based on the risk factors,and its prediction efficiency was then evaluated.Results The incomplete capsule,unsmooth tumor margin,portal vein tumor thrombus,cirrhosis,apparent diffusion coefficient(ADC)value,red blood cell distribution width within 24 h after admission,and aspartate aminotransferase were significantly different between the poor prognosis group and the good prognosis group(P＜0.05),and these indicators were the risk factors affecting the poor prognosis of HCC patients treated with interventional therapy(P＜0.05).Based on the above risk factors,a nomogram model of poor prognosis risk for the HCC patients treated with interventional therapy was constructed,and the sensitivity,specificity,and area under the curve(AUC)for predicting poor prognosis of HCC patients treated with interventional therapy were 90.00％,81.80％and 0.899[95％confidence interval(CI)0.827-0.972],respectively.Conclusion The risk nomogram model of poor prognosis of HCC patients treated with interventional therapy based on incomplete capsule,unsmooth tumor margin,portal vein tumor thrombus,cirrhosis,ADC value,red blood cell distribution width,and aspartate aminotransferase has good predictive efficacy.

Indwelling urinary catheterization is one of the most widely used invasive procedures in clinical practice, playing a critical role in disease diagnosis, treatment, and monitoring. In 2024, the European Association of Urology Nurses (EAUN) released the Best Practice Guidelines for Indwelling Urinary Catheterization in Adults-Transurethral and Suprapubic Catheterization (hereinafter referred to as the Guideline), aiming to provide evidence-based clinical guidance and health education information for healthcare professionals. This article interprets the section on "Nursing Principles" within the Guideline, which spans the entire process of catheter management.

The aim is to help urology nurses and related healthcare personnel gain an in-depth understanding of the recommendations in the Guideline, promote its standardized application in clinical practice, improve the quality of indwelling catheter care, and ensure patient safety.

Objective:To explore the latent class characteristics of demoralization in severely disabled stroke patients, and analyze the differences and influencing factors of each class by latent class analysis.Methods:Convenience sampling was used to select 335 patients in the Neurointensive Care Unit of three Class Ⅲ Grade A hospitals in Anhui Province from October 2023 to March 2024, and were confirmed to be with post-stroke disability through follow-up as research subjects. General Information Questionnaire and Demoralization Scale-Ⅱ were used for a survey. Latent class analysis was used to identify latent classes of demoralization, and multiple logistic regression was used to analyze the influencing factors of different latent classes.Results:A total of 335 questionnaires were distributed, and 321 valid questionnaires were retrieved. The effective recovery rate of the questionnaires was 95.8%. Demoralization of severe stroke patients with disability was classified into four categories of low demoralization (40.2%, 129/321), moderate demoralization with coping loss (12.1%, 39/321), moderate demoralization with goal loss (21.2%, 68/321), and high disability (26.5%, 85/321). Multiple Logistic regression analysis showed that age, gender, per capita monthly income of the family, whether was the economic pillar of the family, long-term residence, and relationship with cohabitants were the influencing factors of demoralization in severe stroke patients with disability (all P<0.05) . Conclusions:There are four latent classes of demoralization in stroke patients with disability, and age, gender, per capita monthly income of the family, whether they are the economic pillar of the family, long-term residence, and relationship with cohabitants are the influencing factors of demoralization in severe stroke patients with disability.

Objective:To translate the Clinical Leadership Needs Analysis Instrument (CLeeNA) into Chinese and to test its reliability and validity.Methods:The source scale was translated based on the Beaton translation model, and cultural debugging was completed through expert consultation and pre-surveys to form the Chinese version of CLeeNA.

Objective To investigate the clinical influencing factors for the occurrence of intracranial hemorrhage(ICH)in the elderly patients with massive ischemic stroke after endovascular therapy(EVT).Methods A retrospective study was conducted on 103 elderly hospitalized patients who underwent EVT due to anterior circulation acute arterial occlusion in our department from March 2021 to December 2023.All of them were diagnosed with massive ischemic stroke before treat-ment.Multivariate logistic regression analysis was used to identify the influencing factors for ICH after EVT treatment.Then based on the obtained factors,a nomogram model was constructed,and its performance efficiency was evaluated.Results After EVT treatment,95 patients had success-ful vascular recanalization,26(25.24％)experienced ICH,10 had symptomatic cerebral hemor-rhage,and 32(31.07％)obtained good functional outcomes after 90 d of follow-up.Multivariate logistic regression analysis that history of alcohol consumption(OR=3.795,95％CI:1.381-10.427,P=0.010),coronary heart disease(OR=2.969,95％CI:1.094-8.059,P=0.033)and bridging thrombolysis(OR=0.284,95％CI:0.091-0.884,P=0.030)were independently influen-cing factors for ICH occurrence in acute ischemic stroke patients after EVT.Our nomogram model based on these three factors had an AUC value of 0.759(95％CI:0.662-0.856).Conclusion Alcohol consumption,bridging thrombolysis,and history of coronary heart disease can predict adverse outcomes in elderly patients with massive ischemic stroke after EVT.

Objective:To compare the efficacy of robot system-assisted versus freehand screw revision for ankylosing spondylitis (AS) with lower cervical fractures.Methods:A multicenter retrospective cohort study was conducted to analyze the clinical data of 57 patients with AS combined with lower cervical fractures admitted to Honghui Hospital Affiliated to Xi'an Jiaotong University School of Medicine, Henan Provincial People's Hospital, Zhengzhou Orthopedic Hospital, and Qilu Hospital of Shandong University, including 46 males and 11 females, aged 38-77 years [(65.4±9.5)years]. Injury segments involved C 3 in 7 patients, C 4 in 13, C 5 in 25, C 6 in 10, and C 7 in 2. All the patients underwent revision surgery, among whom, 22 patients were treated with robot system-assisted cervical pedicle screw placement (robot nailing group, with 190 screws), and 35 with freehand cervical pedicle screw placement (freehand nailing group, with 300 screws). The operative duration, intraoperative bleeding volume, frequency of intraoperative fluoroscopy, incision length, and length of hospital stay of the two groups were compared; the time of single nscrew insertion, the number of single nail revisions, the distance between screws and the anterior cortex, the accuracy of screw placement of grade 0 and grade 0+1 were recorded in the two groups. The visual analogue scale (VAS), Japanese Orthopedic Society (JOA) score, neck dysfunction index (NDI), American Spine Injury Association (ASIA) classification before operation, at 3 days, 3 months after operation and at the last follow-up were compared between the two groups. The complication rate was also noted. Results:All the patients were followed up for 12-16 months [(14.3±2.1)months]. The operative duration, intraoperative bleeding volume, and frequency of intraoperative fluoroscopy were (186.4±12.9)minutes, (486.1±68.6)ml, and (3.4±1.3)times in the robot nailing group, which were shorter or less than (206.7±14.4)minutes, (660.3±45.2)ml, and (13.5±3.6)times in the freehand nailing group ( P<0.01). The incision length was (9.4±2.4)cm in the robot nailing group, longer than (5.6±1.2)cm in the freehand nailing group ( P<0.01), and the length of hospital stay was (3.7±0.4)days, shorter than (4.4±1.4)days in the freehand nailing group ( P<0.01). The length of single nail insertion, the number of single nail revision, and the distance between the screws and the front cortex were (6.5±0.4)minutes, (1.1±0.1)times, and (3.5±1.3)mm in the robot nailing group, which were shorter or less than (11.6±0.2)minutes, (1.5±0.2)times, and (12.4±4.7)mm in the freehand nailing group ( P<0.01). The accuracy of the screw placement in the robot nailing group was 90.0% (171/190) and 95.8% (182/190) with level 0 and 0+1 screws, better than 80.0% (240/300) and 89.0% (267/300) in the freehand nailing group ( P<0.05). There was no significant difference in VAS, JOA score, NDI, or ASIA grading between the two groups before operation ( P>0.05). The VAS, JOA, and NDI scores at 3 days after operation were (3.1±0.6)points, (12.1±1.2)points, and (15.6±2.9)points, respectively in the robot nailing group, which were better than (5.0±1.4)points, (11.3±1.1)points and (22.5±3.7)points, respectively in the freehand nailing group ( P<0.05). No statistically significant difference was observed in the ASIA grade between the two groups at 3 days after operation ( P>0.05). There were no significant differences in VAS, JOA, NDI scores, or ASIA grading between the two groups at 3 months after operation and at the last follow-up ( P>0.05). Compared with those before operation, the VAS, JOA, NDI scores, and ASIA grading were significantly improved at 3 days, 3 months after operation and at the last follow-up in the two groups, which were further improved with the passage of time. Two patients in the robot nailing group had pneumonia, with a complication rate of 9% (2/22), while 2 patients in the freehand nailing group had dural sac rupture and cerebrospinal fluid leakage and 3 had lung infection after operation, with a complication rate of 14% (5/35) ( P<0.05). Conclusion:Compared with freehand nailing, the robot system-assisted nailing revision for AS with lower cervical fracture has more advantages in terms of the operative duration, length of hospital stay, intraoperative bleeding volume, frequency of intraoperative fluoroscopy nailing speed and accuracy, screw holding force, early pain relief, function restoration, and complication rate, despite longer surgical incision.

Objective To investigate the effects of simulated-microgravity on the osteogenic differentiation,primary cilia status,cytoskeleton structure,and the YAP(Yes-associated protein)expression in primary osteoblasts.Methods Primary osteoblasts were isolated from the skull bones of neonatal Wistar rats and cultured in random positioning machine system to simulate the cellular effects of microgravity.The calcified nodules were stained with Arlizarin to assess the cellular mineralization ability,the primary cilia and cytoskeleton were detected by immunofluorescence staining of Arl13b/γ-Tubulin and α-Tubulin,respectively,and the expression of YAP was measured by western blot.Results The cellular osteogenic differentiation were markedly suppressed after treated with simulated microgravity for 24 h,and the ciliated cells decreased from(58.44±3.65)%to(15.76±1.84)%in parallel with a decline of average cilium length from(3.19±0.51)μm to(1.59±0.46)μm.In addition,simulated microgravity induced disassembly of microtubules.Notably,simulated microgravity interfered YAP expression and the inhibition of YAP into nucleus.Furthermore,knockdown of YAP expression in osteoblasts notably reduced primary cilia expression and inhibited osteogenic differentiation.Conclusion Primary cilia is a key organelle of osteoblasts in sensing microgravity and regulating osteogenic differentiation.Interference with YAP expression and inhibition of nuclear YAP entry may play an important role in the deaggregation of primary cilia induced by microgravity.
