ObjectiveTo explore the effect and mechanism of Jianpi Xiaoai prescription （JPXA） in ameliorating the 5-fluorouracil （5-FU） resistance of colon cancer. MethodsA HCT116/5-FU resistant cell line was established. Different concentrations （10%， 15%， 20%） of JPXA-containing serum and drug-free serum were used for intervention， and 10% fetal bovine serum （10% FBS）， fibroblast growth factor receptor （FGFR） inhibitor （AZD4547）， and recombinant fibroblast growth factor 2 （FGF2） were set as the control groups. Sensitive HCT116 cells were used in the FGF2 group， while HCT116/5-FU cells were used in other groups. Drug resistance， the level of FGF2 in the cell culture medium， the mRNA level of FGF2 in cells， and the protein levels of FGF2/FGFR and phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） were determined. The drug-resistant cells were transplanted into the axilla of nude mice to establish a tumor model. The modeled mice were allocated into model， JPXA （15 g·kg^-1）， 5-FU （0.02 g·kg^-1）， JPXA+5-FU （15 g·kg^-1+0.02 g·kg^-1）， AZD4547 （0.012 5 g·kg^-1）， and AZD4547+5-FU （0.012 5 g·kg^-1+0.02 g·kg^-1） groups. The tumor growth and the protein levels of FGF/FGFR and PI3K/Akt in each group were observed. ResultsThe survival rate of HCT116/5-FU cells decreased in all the JPXA groups with different concentrations. The cell survival rate was decreased most obviously in the 20% JPXA group. The level of FGF2 in the cell culture medium and the mRNA level of FGF2 in cells of each JXPA group decreased， and the decrease was the most significant in the 20% group （P<0.01）. HCT116/5-FU cells showed up-regulated protein levels of FGF2 and phosphorylated fibroblast growth factor receptor 1 （p-FGFR1）， but down-regulated protein level of FGFR1 （P<0.01）. JPXA down-regulated the expression of FGF2 and p-FGFR1 and up-regulated the expression of FGFR1 （P<0.05）. In addition， JPXA down-regulated the expression levels of phosphorylated protein kinase B （p-Akt） and phosphorylated mammalian target of rapamycin （p-mTOR）， while up-regulating the expression levels of Akt and Bcl-2-asociated death promoter （Bad） （P<0.05）. Animal experiments showed that the JPXA combined with 5-FU significantly inhibited the growth of drug-resistant tumors， reduced the protein levels of FGF2， p-FGFR1， phosphorylated phosphatidylinositol-3-kinase （p-PI3K）， p-Akt， and p-mTOR， and increased the expression of Bad. It indicated that JPXA can inhibit the FGF2/FGFR1 signaling in colon cancer and regulate PI3K/Akt and downstream signaling pathways. ConclusionJPXA can ameliorate the chemotherapy resistance of colon cancer through down-regulating FGF2 expression and inhibiting the activation of the PI3K/Akt signaling pathway.

Objective:To analyze the clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) complicated by fatigue.Methods:COPD patients enrolled in the RealDTC study from June 2023 to March 2024 were included. Demographic data, history of acute exacerbations in the past year, smoking status, biofuel exposure, occupational exposure, modified Medical Research Council (mMRC) dyspnea score, COPD Assessment Test (CAT) score, forced expiratory volume in the first second predicted of percentage (FEV 1%pred), forced expiratory volume in one second (FEV 1)/forced vital capacity (FVC), and comorbidities (bronchial asthma, bronchiectasis, tuberculosis, cardiovascular disease, diabetes mellitus) were collected. Fatigue was evaluated using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire, with a score ≤43 defined as fatigue. Patients were divided into fatigue and non-fatigue groups, and multivariate regression analysis was used to screen factors associated with fatigue in COPD patients. Results:A total of 597 COPD patients were included, of which 280(46.9%) had fatigue symptoms. Compared with non-fatigue patients, fatigue patients had lower FEV 1%pred, FEV 1/FVC, and body mass index (BMI), higher CAT and mMRC scores, and a higher proportion of occupational exposure, bronchiectasis, and treatment with long-acting β 2-agonists (LABA)/long-acting muscarinic antagonists (LAMA)/inhaled corticosteroids (ICS) (all P<0.05). Multivariate regression analysis showed that high CAT score ( OR=2.312, 95% CI: 1.366-3.911), high mMRC score ( OR=1.484, 95% CI: 1.053-2.091), occupational exposure ( OR=1.513, 95% CI: 1.082-2.116), comorbid bronchiectasis ( OR=2.452, 95% CI: 1.102-5.457), low BMI ( OR=0.935, 95% CI: 0.891-0.981), and high CAT-energy score ( OR=1.301, 95% CI: 1.149-1.473) were risk factors for fatigue in COPD patients. The CAT-energy score was highly correlated with the FACIT-F score ( r=0.260, P<0.001), and a CAT-energy score ≥2 could preliminarily screen COPD patients with fatigue. Conclusions:COPD patients with comorbid fatigue have a heavy symptom burden, are more likely to have a history of occupational exposure and bronchiectasis, and the CAT-energy score is of great reference value for screening COPD patients with fatigue.

Objective:To analyze the clinical characteristics of patients with chronic obstructive pulmonary disease (COPD) complicated by anorexia.Methods:This cross-sectional study included patients registered in the RealDTC study from May 2023 to December 2023. Demographic data, COPD Assessment Test (CAT) score, modified Medical Research Council (mMRC) dyspnea questionnaire score, Clinical COPD Questionnaire (CCQ) score, forced expiratory volume in one second (FEV 1), forced expiratory volume in the first second predicted of percentage (FEV 1%pred), FEV 1/forced vital capacity (FVC), Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade, GOLD group, number of acute exacerbations and hospitalizations in the past year, and score of the Functional Assessment of Anorexia Cachexia Therapy-Anorexia/Cachexia Subscale-12 (FAACT-A/CS-12) were collected. Patients with a FAACT-A/CS-12 score ≤30 were diagnosed as having anorexia. Multivariate logistic regression analysis was used to evaluate the influencing factors of anorexia in COPD patients. Results:A total of 617 COPD patients were included, of whom 109(17.7%) had anorexia. Compared with non-anorexia patients, COPD patients with anorexia had higher age, CAT, mMRC and CCQ scores, and more acute exacerbations and hospitalizations in the past year, while body mass index, FEV 1, FEV 1%pred and FEV 1/FVC were lower (all P<0.05). The proportions of patients with primary education or below, GOLD 3-4 grade and GOLD E group were higher in COPD patients with anorexia (all P<0.05). Logistic regression analysis showed that a CAT score of 10-<20 [odds ratio ( OR)=4.017, 95% confidence interval ( CI): 1.673-59.645], a CAT score of 20-<30 ( OR=9.686, 95% CI: 3.777-24.842), a CAT score of ≥30 ( OR=78.286, 95% CI: 7.654-800.689) and ≥1 hospitalization in the past year ( OR=2.050, 95% CI: 1.292-3.254) were independent risk factors for anorexia in COPD patients (all P<0.05). Conclusions:COPD patients with anorexia have poor lung function, high symptom burden and high risk of acute exacerbation. Clinicians should pay attention to the management of COPD patients with anorexia and take corresponding intervention measures.

Background and Aims:The completeness of lymph node dissection in laparoscopic radical gastrectomy for gastric cancer directly affects postoperative patient prognosis.Indocyanine green(ICG)fluorescence-guided navigation,as an emerging auxiliary technique,enables real-time visualization of lymphatic drainage pathways and enhances surgical precision.This study was performed to evaluate the impact of ICG fluorescence navigation on lymph node dissection,positive lymph node detection,and patient prognosis during laparoscopic D2 radical gastrectomy for gastric cancer.Methods:The clinical data of 168 patients who underwent laparoscopic radical gastrectomy at Zhangzhou Affiliated Hospital of Fujian Medical University from January 2021 to December 2022 were retrospectively analyzed.Among them,51 patients received ICG-guided surgery(ICG group),and 117 underwent conventional surgery(non-ICG group).Perioperative variables,extent of lymph node dissection,positive lymph node detection efficiency,and postoperative survival outcomes were compared between the two groups.Results:There were no statistically significant differences between the two groups in baseline clinicopathologic characteristics,as well as operative time,intraoperative blood loss,postoperative recovery,and incidence of surgical complications(all P>0.05).The ICG group had a significantly higher mean number of lymph nodes dissected than the non-ICG group(48.62 vs.37.20,P<0.001),with a greater proportion of patients achieving≥30 nodes dissected(92.16％vs.69.23％,P=0.001).Stratified analysis showed a significantly higher number of dissected lymph nodes in the ICG group at D2 stations,the supra-pancreatic region(stations 7,8,9,11),in total gastrectomy,T3-4 stage,and stage Ⅲ patients(all P<0.01).In the ICG group,the number and positivity rate of fluorescent lymph nodes were significantly higher than those of non-fluorescent nodes(30.31 vs.17.36;2.03 vs.0.94,both P<0.05).The diagnostic sensitivity of ICG fluorescence imaging for positive lymph nodes was 68.4％,with a negative predictive value of 94.6％for non-fluorescent nodes.No significant differences were observed between the two groups in terms of adjuvant therapy,overall survival(HR=0.737,P=0.471),or disease-free survival(HR=0.502,P=0.089).Conclusion:ICG-guided navigation in laparoscopic radical gastrectomy for gastric cancer is safe and significantly improves lymph node yield,particularly in the supra-pancreatic region,total gastrectomy,and advanced-stage patients.It also enhances positive node detection.However,no survival benefit has been observed in the short term.Further multicenter studies with long-term follow-up are warranted to confirm its clinical value and optimize intraoperative navigation strategies.

This study summarizes the nursing experience of an elderly patient who developed Takotsubo syndrome following mitral valve replacement surgery.Key nursing points include:close monitoring of electrocardiogram and myocardial enzyme spectrum changes for early identification of Takotsubo syndrome;implementation of a multi-dimensional collaborative circulatory support strategy;establishment of a triadic psychological intervention model comprising"environment-communication-family support"to prevent the exacerbation of Takotsubo syndrome based on stressor management;application of multimodal early rehabilitation interventions to shorten mechanical ventilation duration.After meticulous treatment and care,the left ventricular ejection fraction(LVEF)of the patient improved to 46％on postoperative day 12.There were no occurrences of malignant arrhythmias or multiple organ dysfunction.On postoperative day 16,the patient was transferred to a general ward for continued specialized treatment,and on postoperative day 22,the patient was successfully discharged after rehabilitation.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective To investigate the effect of extracellular heat shock protein(HSP)22 on Toll-like receptor(TLR)4/nuclear factor-κB(NF-κB)signaling pathway in oxidative-low-density lipoprotein(ox-LDL)-induced inflammatory damage in coronary endothelial cells(HCAECs).Methods HCAECs were cul-tured in vitro and pretreated with ox-LDL to establish a model of high-lipid-induced endothelial cell injury.Re-combinant human HSP22(rhHSP22)was exogenously treated.The effects of rhHSP22 on the expression of inflammation-related proteins such as interleukin(IL)-8,vascular cell adhesion molecule(VCAM)-1 and NF-κB in endothelial cells and endothelial cell apoptosis were observed.The relationship between HSP22 and TLR4/NF-κB signaling pathway was investigated under the action of TLR4 inhibitor E5564.Western blot was used to detect the expression of IL-8,VACM-1 and NF-κB proteins,and flow cytometry was used to detect the apoptosis of endothelial cells in each group.Results Compared with the CNT group,the relative expression levels of IL-8,VACM-1 and NF-κB protein in the rhHSP22 group,rhHSP22+ox-LDL group,rhHSP22+E5564 group and rhHSP22+E5564+ox-LDL group were significantly increased,and the differences were sta-tistically significant(P<0.05).Compared with the rhHSP22 group,the relative expression levels of IL-8,VACM-1 and NF-κB protein in the rhHSP22+ox-LDL group were significantly increased,and the differences were statistically significant(P<0.05).Compared with the rhHSP22+ox-LDL group,the relative expression levels of IL-8 and VACM-1 in the rhHSP22+E5564+ox-LDL group were decreased,and the differences were statistically significant(P<0.05).Compared with the CNT group,the apoptosis rate in the rhHSP22 group,rhHSP22+ox-LDL group and rhHSP22+E5564+ox-LDL group was significantly increased,and the differ-ence was statistically significant(P<0.05).Compared with the rhHSP22 group,the apoptosis rate in the rhHSP22+ox-LDL group was increased,and the difference was statistically significant(P<0.05).Compared with the rhHSP22+ox-LDL group,the apoptosis rate in the rhHSP22+E5564+ox-LDL group was de-creased,and the difference was statistically significant(P<0.05).Conclusion In ox-LDL-induced inflamma-tory damage of HCAECs,extracellular HSP22 induces the expression of IL-8,VACM-1 and NF-κB proteins by activating the TLR4/NF-κB signaling pathway,and promotes endothelial cell apoptosis.
