Objective To investigate the effect of Scutellarin(Scu)regulating miR-26a-3p/Survivin molecular axis on myocardial ischemia/reperfusion injury(MIRI)in rats and its mechanism.Methods Fifty SD rats were randomly divided into sham group,model group,scutellarin group(Scu),miR-26a-3p agomir group(agomir)and scutellarin+miR-26a-3p agomir group(Scu+agomir)with 10 rats in each group.The animal model of MIRI was established by ligating the anterior descending coronary artery.The rats in each group were given 20 mg/kg Scu or 10 nmol agomir before and during operation,respectively,and the rats in sham group and model group were given the same amount of solvent.At 48 h after operation,the cardiac function of rats was examined by echocardiography.The pathological changes of myocardial tissue were detected by HE staining.The levels of myocardial injury markers creatine kinase isoenzyme MB(CK-MB),lactate dehydrogenase(LDH)and cardiac troponin I(cTnI)in serum and the contents of oxidative markers Malondialdehyde(MDA),superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)in myocardial tissue were detected by biochemical kit.The apoptosis of rat cardiomyocytes was detected by TUNEL staining.The mRNA expression levels of miR-26a-3p and Survivin in rat myocardium were detected by qRT-PCR.Expression levels of Survivin,cyclin-dependent kinase inhibitor(p21)and cleaved-caspase 3 were detected by Western blot.Results Compared with sham group,the pathological damage of myocardial tissue in the model group was serious,the levels of cardiac function LVEDP and serum CK-MB,LDH and cTnI significantly increased(P<0.01),and the levels of LVESP,LVEF and LVFS significantly decreased(P<0.01).The apoptosis level and MDA level of myocardial tissue significantly increased(P<0.01),while the SOD and GSH-Px levels significantly decreased(P<0.01).Meanwhile,the expression levels of miR-26a-3p and cleaved-caspase 3 protein significantly increased(P<0.01),the p21 protein and Survivin mRNA and protein expression levels significantly decreased(P<0.01).Compared with model group,the pathological injury of myocardium in Scu group was significantly improved,the levels of cardiac function LVEDP and serum CK-MB,LDH and cTnI significantly decreased(P<0.01),and the levels of LVESP,LVEF and LVFS significantly increased(P<0.01).The apoptosis level and MDA level of myocardial tissue significantly decreased(P<0.01),while the SOD and GSH-Px levels significantly increased(P<0.01).Meanwhile,the expression levels of miR-26a-3p and cleaved-caspase 3 protein significantly decreased(P<0.01),the p21 protein and Survivin mRNA and protein expression levels significantly increased(P<0.01).However,intervention with miR-26a-3p agomir could significantly reverse the improvement effect of Scu on MIRI in rats.Conclusion Scu can improve cardiac function and myocardial injury and inhibit myocardial cell apoptosis in MIRI rats,and its mechanism may be related to the regulation of miR-26a-3p/Survivin molecular axis.

Objective:To investigate the status of sedentary behavior and its influencing factors among inpatients with stable schizophrenia, providing empirical evidence for developing interventions to reduce sedentary behavior.Methods:A cross-sectional survey design was used to prospectively collect clinical data from 166 inpatients with stable schizophrenia (97 males, 69 females, mean age 56.4±8.4 years) hospitalized at the Shanghai Mental Health Center affiliated with Shanghai Jiao Tong University School of Medicine from February 2024 to May 2024. Sedentary behavior time was assessed using the Sedentary Behavior Questionnaire (SBQ), daily step count was measured via pedometers, and negative schizophrenic symptoms were evaluated using the Scale for the Assessment of Negative Symptoms (SANS). Patients were divided into a non-sedentary behavior group (≥5 000 steps/day, 66 cases) and a sedentary behavior group (<5 000 steps/day, 100 cases). Clinical variables were compared between the two groups, and binary logistic regression was used to identify influencing factors of sedentary behavior.Results:Stable inpatients with schizophrenia exhibited high levels of sedentary behavior, with an average daily sedentary time of (8.03±2.33) hours and a median daily step count of 3 352 (1 258-5 506) steps. Significant differences were observed between sedentary and non-sedentary behavior groups in Age ( t=-2.38),hospitalization duration ( Z=-1.53),blunted affect ( t=-8.37),poverty of thought ( t=-2.45),avolition ( t=-2.45),impoverished interests/social engagement ( t=-2.41),abdominal obesity ( χ2=9.18),and open vs. restricted hospital/wards environment ( χ2=8.88)(all P<0.05). Binary logistic regression analysis identified that hospital/wards environment ( OR=0.314, 95 %CI: 0.125-0.787),hospitalization duration ( OR=1.001, 95 %CI: 1.000-1.001),and the negative symptom of blunted affect ( OR=3.256, 95 %CI: 1.960-5.407)(all P<0.05) were significantly influencing factors for sedentary behavior in patients with stable schizophrenia. Conclusion:Hospitalized patients with stable schizophrenia exhibit high levels of sedentary behavior. Hospital/wards environment and blunted affect are significant factors influencing sedentary behavior.

OBJECTIVE To explore the prognostic significance of the prognostic nutrition index(PNI)in patients with hypopharyngeal cancer undergoing surgical treatment.METHODS Clinical and pathological data of 117 patients with hypopharyngeal carcinoma who underwent surgical treatment at the center of Otolaryngology Head and Neck Surgery of Beijing Friendship Hospital,Capital Medical University from May 2014 to June 2022 were collected.The prognostic significance of hematological indicators such as PNI and neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),and systemic immune inflammation index(SⅡ)were investigated.The time-dependent receiver operating characteristic(tROC)curves were used to analyze the sensitivity and specificity of various hematological indicators and to determine their optimal cutoffvalues.The Kaplan-Meier method was used to plot the postoperative survival curve,and the Cox regression model was used to analyze the correlation between PNI and overall survival(OS)and disease-free survival(DFS).RESULTS 117 patients were enrolled in this cohort,of which 109 were clinically classified as advanced stage(Ⅲ-Ⅳ).63 cases underwent surgery to preserve laryngeal function.The 5-year OS is 46.07％.According to the analysis of the tROC curve,the optimal cutoffvalue for PNI is 46.75.PNI is correlated with tumor T staging,NLR,PLR,and SⅡ.Kaplan Meier univariate analysis showed that PNI was significantly correlated with OS and DFS(P<0.05).In addition,tumor N-stage,postoperative complications,adverse pathological prognostic factors,NLR,PLR,and SⅡ were all significantly correlated with OS(P<0.05).Tumor N-stage,laryngeal preservation,postoperative complications,NLR,and SⅡ were significantly correlated with DFS(P<0.05).The Cox multivariate analysis results indicated that PNI,tumor N-stage,and postoperative complications were independent factors affecting OS and DFS.CONCLUSION Preoperative PNI,tumor N-stage,and postoperative complications are independent risk factors for OS and DFS in patients with hypopharyngeal carcinoma.PNI,as a prognostic indicator for predicting hypopharyngeal cancer patients,is superior to other hematological indicators.

Objective:To explore the predictive value of peripheral blood neutrophil to lymphocyte ratio (NLR) and serum trimethylamine oxide (TMAO) on in-hospital mortality events in patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) upon admission.Methods:A retrospective collection of medical records of 103 AMICS patients admitted to the Shanxi Yingkang Life General Hospital from January 2018 to June 2023 was conducted. The patients were divided into a survival group ( n=78) and a death group ( n=25) based on whether they experienced in-hospital mortality events. Two groups of peripheral blood NLR, serum TMAO, baseline data, and other laboratory indicators were compared. A logistic regression model was used to analyze the risk factors for in-hospital mortality in AMICS patients and a prediction model was constructed. We established receiver operating characteristic (ROC) curves to evaluate the predictive efficacy of peripheral blood NLR, serum TMAO, peripheral blood NLR+ serum TMAO, and predictive model indicators for in-hospital mortality events in AMICS patients. Results:The peripheral blood NLR and serum TMAO levels in the death group were significantly higher than those in the survival group (all P<0.05). The age of the death group was higher than that of the survival group, and the proportion of hypertension, alanine aminotransferase, creatinine, random blood glucose, proportion of patients who did not receive emergency percutaneous coronary intervention (PCI) treatment, peak cardiac troponin I, B-type natriuretic peptide, Gensini score of coronary artery disease, and C-reactive protein were all higher than those of the survival group. Systolic blood pressure and platelet count were lower than those of the survival group, heart rate and erythrocyte sedimentation rate were faster than those of the survival group, and the pre hospital time was longer than that of the survival group. The differences were statistically significant (all P<0.05). The results of binary logistic regression analysis showed that after adjusting for confounding factors such as age, male proportion, body mass index, proportion of old myocardial infarction, proportion of hypertension, and proportion of PCI history, advanced age, long pre hospital time, failure to receive emergency PCI, elevated peripheral blood NLR, and elevated serum TMAO were independent risk factors for in-hospital mortality in AMICS patients ( P<0.05). The predictive model was obtained as 0.734×age+ 0.277×pre hospital time+ 2.263×failure to receive emergency PCI+ 0.549×peripheral blood NLR+ 0.608×serum TMAO-26.923. The ROC curve results showed that the area under the curve (AUC) values of peripheral blood NLR, serum TMAO, peripheral blood NLR+ serum TMAO, and predictive model indicators for predicting in-hospital mortality events in AMICS patients were 0.744, 0.781, 0.825, and 0.921, respectively. When the optimal cutoff value was taken, the sensitivities were 0.880, 0.520, 0.680, and 0.880, and the specificities were 0.526, 0.923, 0.872, and 0.821, respectively. Conclusions:Advanced age, long pre hospital duration, failure to undergo emergency PCI, elevated peripheral blood NLR, and elevated serum TMAO are independent risk factors for in-hospital mortality in AMICS patients. Peripheral blood NLR, serum TMAO, peripheral blood NLR+ serum TMAO, and prediction models all have certain predictive value for in-hospital mortality events in AMICS patients. Among them, the sensitivity and specificity of the prediction models are high, and the efficacy is good.

Cervical metastatic carcinoma from unknown primary lesion(CMCUP) usually refers to a malignant tumor confirmed by histological and pathological examination as cervical lymph node metastasis. However, after systematic medical history collection, physical examination, endoscopy, and imaging examinations, it is still unclear whether the primary lesion is cervical metastatic malignant tumor. Although with the development of examination techniques such as endoscopy and imaging, the detection of unknown primary lesions has been increasing year by year in recent years, there are still some cases where the primary lesion cannot be diagnosed through known examination methods. For the diagnosis and treatment of patients with unknown primary metastatic cancer in the neck, it is necessary to correctly identify clinical manifestations and use the least invasive approach to achieve diagnosis and treatment, avoiding inappropriate diagnostic methods. The current situation of standardized treatment is not optimistic, and there is an urgent need to pay attention to the standardized diagnosis and treatment of cervical metastatic cancer from unknown primary lesions. This article will focus on the key diagnostic and treatment issues and the latest progress of CMCUP clinical attention, providing reference for the standardized clinical diagnosis and treatment of cervical metastatic cancer from unknown primary lesions.

ObjectiveTo explore the effect of Anmeidan on the sleep quality and serum levels of brain-derived neurotrophic factor （BDNF）， glial fibrillary acidic protein （GFAP）， and irisin in the patients with chronic insomnia. MethodA multicenter， randomized， double-blind， placebo-controlled clinical study was carried out， including 480 patients with chronic insomnia （deficiency syndrome） in Wuhan （Hubei）， Guangzhou （Guangdong）， and Lanzhou （Gansu）. They were randomized into an observation group and a control group at a ratio of 1∶1. The observation group was orally administered with Anmeidan granules at a dose of 11 g， 3 times per day， and the control group with Anmeidan simulant at a dose of 11 g， 3 times per day， Both groups of patients received sleep education after enrollment. After 4 weeks of medication， the Athens insomnia scale （AIS） scores， Spiegel scale scores， and serum levels of BDNF， GFAP， and irisin were compared between the two groups as well as between before and after treatment. ResultA total of 480 adult patients with chronic insomnia were enrolled in this study， with 64 patients falled off. Finally， the 415 patients were included in the analysis， including 213 patients in the observation group and 202 patients in the control group. There was no difference in age or sex between the two groups of patients. Compared with before treatment， the treatment in both groups decreased the AIS and Spiegel scores （P<0.01）. After treatment， the observation group had lower AIS and Spiegel scores than the control group （P<0.01）. The treatment in the observation group slightly lowered the level of BDNF， elevated the level of irisin （P<0.05）， and lowered the level of GFAP （P<0.05） in the serum. After treatment， the observation group showed higher level of irisin （P<0.05） and lower levels of BDNF and GFAP in the serum than the control group. ConclusionAnmeidan may improve the sleep quality of patients with chronic insomnia by elevating the irisin level and lowering the GFAP level in the serum.

Objective:To explore the influencing factors of the poor sustainability of the evidence-based practice project for irritant dermatitis around urostomy.Methods:This is a qualitative study. From April to May 2020, 12 nurses working in the Urology Surgery of Peking University First Hospital were selected by purposive sampling for the semi-structured interview. The integrated-Promoting Action on Research Implementation in Health Services framework (i-PARIHS framework) was applied to analyze and extract the obtained data.Results:The interview results found that, in terms of transform (evidence) , the localization and continuity of evidence for the evidence-based practice project of irritant dermatitis around urostomy needed to be improved, including the high matching between evidence and practice environment, and the insufficient continuity of evidence application. In terms of transform recipients, the leadership of project practitioner needed to be improved, including the conflict between the roles of practitioners and researchers, the lack of knowledge reserves of practitioners, and the conflict among the values of practitioners. In terms of organizational environment, the leadership of managers and the imformatization degree of project needed to be improved, including insufficient support from leaders and insufficient facilities.Conclusions:At the initial stage of formulating the nursing evidence-based practice project, the project implementer should fully incorporate the opinions of stakeholders for localization debugging, and consider the sustainability of the project. In addition, the leadership of managers, nurses and interns should be increased, the use and training of urostomy talents should be strengthened, the training of urostomy knowledge should be continued, the information-based follow-up system should be improved, and the intervention strategy should be continuously adjusted to ensure the project is carried out.
