Objective To investigate the prevalence of comorbidity of oral frailty and sarcopenia in elderly inpatients,and to explore their influencing factors,so as to provide a basis for formulating targeted interventions for patients with oral frailty and sarcopenia.Methods A total of 515 elderly patients hospitalized in 3 tertiary hospitals in Zhengzhou City and 1 second-class hospital in Shangqiu City from January 2024 to April 2024 were selected as the research subjects by convenience sampling,and the general information questionnaire,Oral Frailty Index-8,Sarcopenia Screen Questionnaire,Mini Nutritional Assessment Short Form,Social Support Rating Scale and Hospital Anxiety and Depression Scale(HADS)were used for investigation.Logistic regression was used to analyze the influencing factors of oral frailty and sarcopenia comorbidities in elderly inpatients.Results 508 valid questionnaires were collected.The prevalence of sarcopenia and oral frailty in elderly inpatients was 22.8％,and age,dysphagia,number of chronic diseases,and history of hypertension or stroke,multiple drug use,depression,bad nutrition and low level of social support were the risk factors(P＜0.05).Conclusion The incidence of oral frailty combined with sarcopenia was higher in elderly hospitalized patients.Nurses should take nursing measures according to its influencing factors to prevent and control the development of oral frailty combined with sarcopenia.

Pulmonary hypertension (PH) is a group of progressive diseases characterized by pulmonary vascular remodeling,and some patients already have right heart insufficiency at the time of diagnosis. Therefore,early diagnosis of PH is essential to improve patients' quality of life and prolong survival. Biomarkers are an important indicator for early diagnosis of the disease,and there are many traditional biomarkers for PH diagnosis,but the sensitivity and specificity are low. With the progress of research,some new biomarkers have been shown to predict disease progression in early PH and play an important role in the early diagnosis of PH. This study reviews the research progress of biomarkers of PH from the aspects of right heart insufficiency,endothelial dysfunction,pulmonary artery smooth muscle dysfunction,inflammation,and in situ thrombosis to provide exploration direction and reference value for early diagnosis of PH.

Objectives:To systematically evaluate the incidence and risk factors of titanium mesh subsidence following anterior cervical corpectomy and fusion(ACCF),and to explore the clinical impact of titanium mesh subsidence.Methods:Databases including CNKI,WangFang,VIP,China Biology Medicine disc(CBM),PubMed,Embase,Cochrane Library,and Web of Science were searched for case-control and cohort studies published from the inception of each database to June 2024 about the risk factors of titanium mesh subsi-dence following ACCF.The Newcastle-Ottawa scale(NOS)was used to assess the quality of the included studies.Basic information(first author,publication year,study type,definition of subsidence,assessment time,sample size,number of subsidence cases,and subsidence incidence),reported risk factors(age,sex,BMI,sur gical segment,number of surgical segments,smoking,hypertension,diabetes,fusion segment height,C2-7 Cobb angle,segment angle,vertebral body quality,titanium mesh tilt angle,titanium plate type,screw-plate angle,and titanium mesh placement),cervical JOA score,JOA score improvement rate,and fusion rate were extracted and analyzed using Stata 18.0 software for meta-analysis.Results:A total of 16 studies were in-cluded,and all were case-control studies with NOS scores ≥7.A total of 1562 patients were included,with 555 cases of titanium mesh subsidence.The meta-analysis showed that the incidence of titanium mesh subsi-dence after ACCF was 37％.Risk factors for titanium mesh subsidence included older age[MD=2.680,95％CI(1.228,4.132),P=0.000],female[OR=0.71,95％CI(0.56,0.90),P=0.004],smoking[OR=1.924,95％CI(1.108,3.342),P=0.020],osteoporosis[MD=-62.997,95％CI(-86.670,-39.323),P=0.000],a big number of surgical seg-ments[OR=0.096,95％CI(0.054,0.172),P=0.000],posterior placement of titanium mesh[MD=0.743,95％CI(0.605,0.968),P=0.026],excessive intervertebral distraction[MD=1.317,95％CI(0.752,1.881),P=0.000],seg-ment angle(titanium mesh expansion angle)[MD=0.887,95％CI(0.117,1.657),P=0.024],and a big titanium mesh tilt angle[MD=4.475,95％CI(1.725,7.225),P=0.001].Titanium mesh subsidence was associated with a decrease in cervical JOA score[MD=-0.542,95％CI(-0.947,-0.137),P=0.009],JOA score improvement rate[MD=-11.003,95％CI(-15.315,-6.691),P=0.000],and cervical fusion rate[OR=3.003,95％CI(1.019,8.854),P=0.046].Conclusions:The current evidence indicates that older age,female,smoking,osteoporosis,a big number of surgical segments,posterior placement of titanium mesh,excessive intervertebral distraction,and big titanium mesh expansion angle(segment angle)and titanium mesh tilt angle are the risk factors for titanium mesh subsidence after ACCF.Cage subsidence after ACCF can impair intervertebral fusion and reduce the overall effectiveness of the surgery,and therefore warrants careful clinical attention.

Objective:To explore the dual mediating effects of health belief and depression among health knowledge, social support, and health behaviors based on the capacity, opportunity, motivation-behavior (COM-B) model, and analyze the influencing factors of health behaviors in patients with ischemic stroke.Methods:This multi-center cluster sampling research recruited ischemic stroke patients ( n=1 696) who were hospitalized in neurology departments of five tertiary hospitals in Henan Province from October 2023 to October 2024. A cross-sectional investigation was conducted using the general information questionnaire, social support rating scale (SSRS), stroke prevention knowledge questionnaire(SPKQ), short form health belief model scale(SF-HBMS), health promoting lifestyle profile-Ⅱ (HPLP-Ⅱ), and patient health questionnaire-9(PHQ-9) to ultimately reveal the pathways and effect sizes among variables. Partial correlation analysis and multiple linear stepwise regression analysis were conducted to examine the relationships among social support, health knowledge, health belief, health behaviors, and depression in stroke patients by SPSS 26.0 software. Structural equation modeling was constructed using AMOS 28.0 software, and the mediating effect was tested using the Bootstrap method. Results:The scores of social support, health knowledge, health belief, and health behaviors among ischemic stroke patients were (37.46±9.94), (26.56±6.84), (75.62±12.62) and (130.79±26.27), respectively. The score of depression was 5.00 (2.00, 8.00). Health behaviors were positively correlated with health knowledge, social support, and health belief( r=0.333, 0.246, 0.267, all P<0.05), while negatively correlated with depression ( r=-0.146, P<0.05). Multiple linear stepwise regression analysis showed that health knowledge, social support, health belief, and depression were all influencing factors of health behaviors in ischemic stroke patients (all P<0.05). Health belief (effect value=0.068, 95% CI=0.048-0.093) and depression (effect value=0.009, 95% CI=0.003-0.018) both played partial mediating roles between health knowledge and health behaviors, accounting for 17.3%(0.077/0.446) of the total effect. Meanwhile, health belief (effect value=0.045, 95% CI=0.029-0.063) and depression (effect value=0.016, 95% CI=0.008-0.027) both played partial mediating roles between social support and health behaviors, accounting for 26.5%(0.061/0.230) of the total effect. Conclusion:Health knowledge and social support can not only directly influence health behaviors but also indirectly affect them through health belief and depression in patients with ischemic stroke.

ObjectiveTo explore the mechanism of Huanglian Wendantang on damp-heat type diabetes enteropathy rats based on the G protein coupled bile acid receptor 5/glucagon like peptide-1 （TGR5/GLP-1） signaling pathway and intestinal flora. MethodsA total of 72 male Sprague Dawley （SD） rats were adaptively fed for one week. Twelve SD rats were randomly selected as a blank group and fed with an ordinary diet. The rest of the SD rats were fasted for 12 hours without water. A rat model with damp-heat type diabetes enteropathy was made by left intraperitoneal injection of streptozotocin （55 mg·kg^-1） and high sugar and high fat diet （20% sucrose solution + high fat diet） in a humid and hot environment （artificial climate box： temperature 30-34 ℃， relative humidity： 85%-95%）. After successful modeling， the rats were randomly divided into a model group， a metformin group （200 mg·kg^-1）， low-dose， medium-dose， and high-dose Huanglian Wendantang groups （7.10， 14.20， 28.39 g·kg^-1）， with 12 rats in each group. The normal group and the model group were orally administered with physiological saline once a day for 6 consecutive weeks. During the observation period， the weight and blood glucose levels of rats were measured and recorded weekly. After the administration， fresh feces were collected from rats， and 16S rRNA sequencing technology was used to study the differences and changes in intestinal flora among different groups. The levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in the serum of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and the pathological morphological changes of colon tissue were examined. The expression of TGR5 and GLP-1 in colon tissue was detected by immunohistochemistry， and the expression of TGR5 and GLP-1 proteins in colon tissue was measured by Western blot. ResultsCompared with the blank group， the model group showed a decrease in body weight， an increase in blood glucose， and significant damp-heat symptoms. The levels of IL-6 and TNF-α in serum were significantly increased （P<0.01）. The expression of TGR5 and GLP-1 was decreased （P<0.01）， and the pathogenic bacteria were increased. Compared with the model group， the treatment groups exhibited improvements in body weight， blood glucose levels， and damp-heat syndrome in rats. Among them， the high-dose group of Huanglian Wendantang displayed the most significant improvement effect， with significantly reduced inflammation levels （P<0.01） and elevated expression of TGR5 and GLP-1 （P<0.01）. Colonic pathological sections showed that Huanglian Wendantang could effectively ameliorate colonic pathological changes. The 16S rRNA sequencing result indicated a significant increase in beneficial bacteria in the treatment groups. ConclusionHuanglian Wendantang can effectively ameliorate the damp-heat symptoms and blood glucose levels in rats with damp-heat type diabetes enteropathy， and it may exert an effect by regulating the TGR5/GLP-1 signaling pathway and intestinal flora disorder.

BACKGROUND:Impaired hamstring muscle strength,anterior patellar pain,high incidence of osteoarthritis,and loss of proprioception after anterior cruciate ligament reconstruction lead to poor functional recovery due to a higher incidence of osteoarthritis and loss of proprioception.Arthroscopic repair of the anterior cruciate ligament combined with dynamic or static internal brace repair preserves the original ligament structure and results in favorable short-term outcomes. OBJECTIVE:To prospectively observe the efficacy and imaging findings of modified double-bundle arthroscopic repair of the anterior cruciate ligament after Sherman type Ⅰ injury METHODS:From January 2020 to September 2022,a total of 60 patients with anterior cruciate ligament injury admitted at the Department of Sports Medicine,Foshan Hospital of Traditional Chinese Medicine were included and divided into two groups(n=30 per group)according to the treatment protocols.The functional repair group was treated with double bundle repair combined with internal brace fixation,and the reconstruction group was treated with single bundle anatomical reconstruction of autologous hamstring muscle.All cases were followed up for 12 months after surgery,and International Knee Documentation Committee score,Lysholm score and KT-1000 difference between the affected and healthy sides of the two groups were evaluated at 3,6 and 12 months after surgery. RESULTS AND CONCLUSION:Three months after surgery,International Knee Documentation Committee scores,Lysholm scores and KT-1000 difference between the affected and healthy sides were significantly different between the two groups(P＜0.05),and the functional repair group was better than the reconstruction group.At 6 and 12 months after surgery,there was no significant difference in International Knee Documentation Committee score,Lysholm score and KT-1000 difference between the two groups(P＞0.05).To conclude,anterior cruciate ligament repair preserves the original ligament structure,avoids drilling larger marrow tracts and removing autologous tendons for reconstruction,reduces the damage to the original normal structure,and has fewer complications.Early postoperative efficacy is better than that of anterior cruciate ligament reconstruction with stumps,but there is no significant difference in the efficacy of the two groups 6 months after surgery.

Pulmonary hypertension(PH)is a fatal disease characterized by pulmonary vascular remodeling,ultimately leading to right heart failure and death.Current treatments for PH are suboptimal,with no substantial improvement in overall survival among patients with advanced PH.Despite some progress in understanding the pathogenesis of PH,further studies at the molecular level are needed to develop more effective treatments for PH.Recent research has shown that long non-coding RNAs(lncRNAs)have an important regulatory function in the pathophysiological process of PH,and may thus be potential disease biomarkers and therapeutic targets.In this paper,we review recent progress in our understanding of the molecular mechanisms of lncRNAs in PH.
