OBJECTIVE To construct a pharmaceutical care framework suitable for elderly individuals in nursing homes， so as to provide standardized content guidance for relevant practice. METHODS The initial items of pharmaceutical care content in n ursing homes were drafted through literature research and semi-structured interviews. Delphi method was used to conduct correspondence consultation among 38 experts from related fields in Xinjiang. The expert positive coefficient， authority coefficient， and Kendall’s W were calculated， and the analytic hierarchy process was employed to determine the weight of each item. After thorough discussion among the research team members， the pharmaceutical care framework suitable for elderly individuals provided by hospital pharmacists collaborating with nursing homes was finalized. RESULTS The questionnaire recovery rates for both rounds of expert correspondence consultation were 100%， with an authority coefficient ＞0.8 and Kendall’s W ranging between 0.153 and 0.185 （ P ＜0.001）. A total of 7 primary items and 31 secondary items were ultimately determined， with the consistency ratio of the item weights all being less than 0.1. Based on the integration of importance and feasibility， among the primary items， “assessment of pharmaceutical care needs” was assigned the highest weight. Among the secondary items， highly practical items such as “survey of pharmaceutical care needs”“guidance on usage and dosage”“methods for correctly reading drug package inserts”， and “self-management of common chronic diseases in the elderly” were assigned relatively high comprehensive weights. CONCLUSIONS The pharmaceutical care framework suitable for elderly individuals provided by hospital pharmacists collaborating with nursing homes， which was constructed based on the Delphi method， demonstrates good scientific validity and reliability， and can serve as a reference for pharmacists to provide pharmaceutical care in nursing homes.

Objective: To evaluate the effects of high-frequency repetitive transcranial magnetic stimulation (rTMS) combined with smoking cessation on patients with stable chronic obstructive pulmonary disease (COPD), so as to provide references for slowing down the decline of pulmonary function and improving clinical prognosis. Methods: Patients with stable COPD, tobacco dependence, and aged ≥50 years who attended the Department of Respiratory and Critical Care Medicine of Zhengzhou First People's Hospital from June 2021 to June 2024 were enrolled and randomly divided into the control group and the intervention group. The control group received comprehensive smoking cessation interventions, while the intervention group was additionally treated with high-frequency rTMS for 4 weeks on the basis of the interventions for the control group. Basic information including gender, COPD classification, and smoking duration was collected. The visual analogue scale (VAS) for cigarette craving and Pittsburgh Sleep Quality Index (PSQI) were used to assess nicotine craving and sleep quality, respectively. Pulmonary function indicators such as forced expiratory volume in one second as percentage of predicted value (FEV1%pred), FEV1/forced vital capacity (FEV1/FVC) and inspiratory capacity (IC) were measured using a pulmonary function instrument. The Clinical COPD Questionnaire (CCQ) and the St. George's Respiratory Questionnaire (SGRQ) were used to evaluate quality of life. The differences in the above indicators between the two groups before and after intervention were compared using repeated-measures analysis of variance. Results: The intervention group included 69 male patients (92.00%), with a median age was 71.00 (interquartile range, 29.00) years. The control group included 72 male patients (96.00%), with a median age was 70.00 (interquartile range, 29.00) years. There were no statistically significant differences between the two groups in gender, age, COPD classification, smoking duration and smoking index (all P>0.05). Repeated-measures analysis of variance indicated significant group-time interactions in VAS score, PSQI score, IC, CCQ score and SGRQ score (all P<0.05). After intervention, the intervention group showed greater decreases in VAS, PSQI, CCQ and SGRQ scores, and a greater increase in IC than the control group. Conclusion The high-frequency rTMS combined with smoking cessation supervision was superior to smoking cessation intervention alone in reducing nicotine craving, improving sleep quality and IC, and enhancing quality of life among patients with stable COPD.

Objective:To study the effect of preoperative pancreatic duct stent placement in enucleation (EN) of pancreatic tumor adjacent to the main pancreatic duct (MPD).Methods:Clinical data of 56 patients with benign or borderline pancreatic tumor adjacent to the MPD undergoing EN in the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University from January 2022 to September 2024 were retrospectively analyzed, including 25 males and 31 females, aged (32.0±5.5) years. Among the patients, 35 (62.5%) were solid pseudopapillary neoplasm, 15 (26.8%) were neuroendocrine tumor, and 6 (10.7%) were serous cystic tumor. According to whether the pancreatic duct stent was placed through encoscopic retrograde cholangiopancreatography preoperatively, patients were divided into the stent group ( n=20, observation group) and no-stent group ( n=36, control group). The operation time, intraoperative pancreatic duct injury, tumor enucleation time and blood loss, grade B/C pancreatic fistula and postoperative hospital stay were compared between the two groups. Results:All patients underwent EN successfully. The operation time in the observation group was shorter than that in the control group [150.0 (143.5, 159.0) vs 158.0 (150.0, 180.0) min, Z=-2.08, P=0.031], and the rate of intraoperative MPD injury in the observation group was lower than that in the control group [10.0% (2/20) vs 38.9% (14/36), χ2=5.26, P=0.022]. The tumor enucleation time and blood loss were comparable between the two groups (both P>0.05). The rate of postoperative grade B/C pancreatic fistula in the observation group was lower than that in the control group [15.0% (3/20) vs 41.7% (15/36), χ2=4.19, P=0.041], and the postoperative hospital stay was also shorter in the observation group [(7.9±1.6) vs (9.3±2.1) d, t=-2.57, P=0.014]. Conclusion:Under the premise of matured endoscopic operation, preoperative pancreatic duct stent placement through ERCP in the EN of pancreatic tumor adjacent to the MPD can protect the MPD during operation, reduce the occurrence of postoperative grade B/C pancreatic fistula, and shorten the postoperative hospital stay.

Objective To investigate the current nursing practice of nurses specializing in nutritional support in ICUs and analyze their influencing factors in order to improve the training program and promote the development of standardized and precise nursing practice.Methods Convenience sampling method was used to select nutritional support nurses in ICUs in 29 provinces(autonomous regions and municipalities)from October 2023 to March 2025,and the self-developed questionnaire on nursing practice behaviors of nutritional support nurses in ICUs was used to conduct the survey.SPSS 21.0 software was used for descriptive analysis and multiple linear regression analysis.Results A total of 774 questionnaires were distributed,and 766 valid questionnaires were collected,with a recovery rate of 98.97％,and the score of the questionnaire on nursing practice behaviors of nurses specializing in nutritional support in ICU was(90.41±1 1.82).The results of multiple linear regression analysis showed that gender,presence of a nutritional support nursing team in the hospital,a standardized process of nutritional support nursing in the department,clear positional responsibilities of the nutritional support nursing team members,and inclusion of the nutritional support status of the patients in the quality management of the department were the factors influencing the nursing practice behavior scores of the nurses specializing in nutritional support in ICUs(P＜0.05).Conclusion Nurses in the ICUs have a high level of nursing practice behavior,but there is a need for further standardization in parenteral nutrition infusion and monitoring of complications.ICU nursing managers should formulate improvement strategies to address the weaknesses of clinical practice,strengthen nutritional support training,and improve the quality management program,and further improve the practical ability of nurses specializing in nutritional support.

Objective: The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB). Materials and Methods: This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB. Results: In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%). Conclusion The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

Objective To investigate the mechanism of DNA methyltransferase 1(DNMT1)inhibitor combined with extracellular signal-regulated kinase 1(ERK1),homeodomain-interacting protein kinase 2(HIPK2),and glycogen synthase kinase 3 β(GSK3 β)inhibitors in synergistically inducing apoptosis and protein arrest in relapsed and refractory acute myeloid leukemia(AML)cells.Methods Three therapeutic targets,including ERK1,HIPK2,and GSK3β,were screened based on the Gene Expression Omnibus(GEO),The Cancer Genome Atlas(TCGA)database,and Ex-pression 2 Kinases database.Human AML cell line U937 cells were treated with DNMT1 inhibitor a-lone or combined with ERK1,HIPK2,or GSK3β inhibitors.Cell viability was detected using the CCK-8 method.Apoptosis rate was analyzed by flow cytometry,and cell cycle distribution was de-termined by propidium iodide(PI)staining.The mRNA expression levels of DNMT1,ERK1,HIPK2,and GSK3β were detected by real-time fluorescent quantitative reverse transcriptionpoly-merase chain reaction(RT-qPCR).Protein expressionlevels of DNMT1,ERK1,HIPK2,and GSK3β were detected by immunoblotting.Results DNMT1 inhibitor significantly inhibited the cell viability of U937 cells,and significantly induced apoptosis and cell cycle arrest in U937 cells(P＜0.05).When DNMT1 inhibitor was combined with ERK1,HIPK2,or GSK3β inhibitors,cell via-bility and apoptosis rate were significantly reduced(P＜0.05).DNMT1 inhibitor alone or its com-bination with ERK1,HIPK2,and GSK3β inhibitors induced U937 cell arrest in the G0/G,phase,with a significant increase in the proportion of cells in the G0/G1 phase in the combination group(P＜0.05).The combination of DNMT1 inhibitor with ERK1,HIPK2,and GSK3β inhibitors sig-nificantly reduced the mRNA expression levels in DNMT1,ERK1,HIPK2,and GSK3β in U937 cells(P＜0.05).Similarly,the combination therapy significantly reduced the protein expression levels of DNMT1,ERK1,HIPK2,and GSK3β in U937 cells(P＜0.05).Conclusion DNMT1 inhibitor combined with ERK1,HIPK2,and GSK3 β inhibitors can synergistically induce apoptosis and protein arrest in relapsed and refractory AML cells,providing a novel strategy for combined tar-geted therapy of AML.

Objective:To investigate the current status of peripherally inserted central catheter (PICC) -associated thrombosis prevention nursing practices among surgical nurses, and to provide a scientific basis for targeted future interventions.Methods:A convenience sampling method was used to select 3 151 surgical nurses from tertiary hospitals in 11 provinces and municipalities who attended the Surgical Nursing Academic Symposium of the Chinese Nursing Association between April and May 2023. The survey utilized a standardized questionnaire assessing current practices in PICC-associated thrombosis prevention among clinical nurses.Results:A total of 3 151 questionnaires were distributed, and 2 341 valid responses were collected, yielding a valid response rate of 74.29% (2 341/3 151) . Among the respondents, the training rate on PICC-associated thrombosis prevention was only 62.45% (1 462/2 341) , and just 1.28% (30/2 341) had received full-time (off-duty) training. The usage rate of standardized procedures for PICC-related thrombosis prevention was 92.40% (2 163/2 341) , and the risk assessment rate was 79.79% (1 868/2 341) . Compared to urology and cardiothoracic surgery departments, breast surgery departments had significantly higher rates of thrombosis risk assessment ( P<0.05) . Additionally, 56.69% (1 327/2 341) of surgical nurses used risk assessment tools specific to PICC-associated thrombosis. Among non-pharmacological prevention measures, the implementation rate of encouraging patients to perform grip strength exercises was only 68.26% (1 598/2 341) . Conclusions:The current level of PICC-associated thrombosis prevention nursing among surgical nurses needs further improvement. Efforts should be strengthened in professional training, implementation of standardized protocols, risk assessment, and non-pharmacological interventions.

Objective:To investigate the expression and biological function of AHNAK nucleoprotein 2(AHNAK2)in thyroid cancer.Methods:The expression of AHNAK2 in thyroid cancer tissues was analyzed using The Cancer Genome Atlas(TCGA),Gene Expression Omnibus(GEO),and Human Protein Atlas(HPA)databases.The correlation between AHNAK2 expression and patients'prognosis,clinicopathological characteristics,immune cell infiltration,and subcellular localization was evaluated.AHNAK2 mRNA expression in thyroid cancer cells was detected by RT-qPCR.A stable AHNAK2 knockdown TPC-1 cell line was established via lentiviral transfection,and the transfection efficiency was validated using RT-qPCR and Western blot.TPC-1 cells were divided into the sh-NC and sh-AHNAK2 groups.The impact of AHNAK2 knockdown on TPC-1 cell proliferation,migration,and invasion was assessed using colony formation assay,CCK-8 assay,wound healing assay,and Transwell assay.Results:AHNAK2 was up-regulated in thyroid cancer tissues and was associated with poor prognosis.It was primarily localized in the cytoplasm and cytoplasmic membrane.GO analysis revealed that AHNAK2 was mainly enriched in biological processes such as organelle disassembly,cellular components such as the spindle,and molecular functions such as microtubule binding.KEGG pathway analysis indicated that AHNAK2 was primarily enriched in the cell cycle pathway.Immune infiltration analysis suggested that AHNAK2 expression was positively correlated with macrophage infiltration and negatively correlated with plasmacytoid dendritic cell infiltration in thyroid cancer.AHNAK2 was overexpressed in multiple thyroid cancer cell lines.In vitro experiments demonstrated that AHNAK2 knockdown inhibited the proliferation,migration,and invasion of TPC-1 cells.Conclusion:AHNAK2 may serve as an important prognostic biomarker and immunotherapy target for thyroid cancer,as it can promote the proliferation,migration and invasion of thyroid cancer cells.
