Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective:To understand the effect of vitamin B1 on lymphocyte function in simulated microgravity.Methods:Splenocytes of mice were isolated,and the rotatary cell culture system was used to simulate microgravity.Lymphocytes were stimulated with mitotic agents Concanavalin A,and cells were treated with different concentrations of vitamin B1,proliferation indexes of lympho-cytes and levels of cytokines in supernatant were detected.Results:Simulated microgravity could inhibit proliferation of splenic lym-phocytes,and decrease levels of cytokines,while vitamin B1 could promote lymphocyte proliferation and cytokines production in cells cultured in simulated microgravity in a dose dependent manner.Conclusion:Vitamin B1 may attenuate the inhibitory effect of simulated microgravity on lymphocytes by regulating cell proliferation and secretion of cytokines.

Objectives:This study aims to explore the effects of pioglitazone on the attenuation of ventricular arrhythmias(VAs)induced by β1-adrenergic receptor autoantibodies(β1AAb)and its potential mechanisms. Methods:48 SD rats were uniformly randomly divided into four groups using number table:control group received vehicle injection,β1AAb group received back multi-point injection of β1AR-ECLⅡ antigen peptide with adjuvant,2 mg/(kg·time),pioglitazone group received pioglitazone gavage for 2 weeks after 8 weeks of immunization,4 mg/(kg·d),and GW9662 group received pioglitazone+GW9662 intraperitoneal injection for 2 weeks after 8 weeks of immunization,1 mg/(kg·d).Powerlab recorded electrocardiograms and blood collection every 2 weeks.Baseline and week 10 echocardiography were recorded,followed by electrophysiology,histopathology,immunohistochemical staining,and electron microscopy examination after 10 weeks. Results:Compared to control group,β1AAb group showed a higher incidence of ventricular arrhythmias,shorter ventricular effective refractory period(VERP),longer action-recovery interval(ARI),lower left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS),lower positive staining area ratio of glucose transporter 1(GLUT1)and carnitine palmitoyltransferase 1a(CPT1a),all P＜0.05.Mitochondrial morphology abnormalities and network damage were also significantly observed(P＜0.05).In contrast to β1AAb group,pioglitazone group showed a reduced incidence of ventricular arrhythmias,prolonged VERP,shortened ARI,recovered LVEF and LVFS,increased the positive staining area ratio of GLUT1 and CPT1a,all P＜0.05.Improvement was observed in mitochondrial morphology abnormalities and network damage(P＜0.05).Compared to pioglitazone group,GW9662 group exhibited a higher incidence of ventricular arrhythmias,shorter VERP,and longer ARI,lower LVEF and LVFS,lower positive staining area ratio of GLUT1 and CPT1a,all P＜0.05.Mitochondrial morphology abnormalities and network damage did not recover(P＜0.05). Conclusions:Pioglitazone can reduce VAs induced by β1AAb,improve ventricular electrical conduction and activation recovery time heterogeneity,and mitigate ventricular remodeling caused by β1AAb at the tissue pathology level,accompanied by upregulation of ventricular cardiomyocyte glucose and lipid transport channel proteins and repair of damaged mitochondrial networks.

Objective To evaluate the reliability and validity of the Chinese version of the hyperacusis scale and estimate its applicability in the Chinese population.Methods The patients admitted to the Department of Oto-laryngology of Xijing Hospital from June 2017 to December 2017 were surveyed.A total of 300 questionnaires were sent out and 293 valid questionnaires were collected with effective response rate of 97.67％.All participants comple-ted a basic information survey,pure tone audiometry and fill in the Chinese version of the hyperacusis scale.The re-liability and validity of this scale were evaluated.Results Among the 293 respondents,243(82.93％)were compli-cated with tinnitus.A total of 181 cases(61.77％)were subjectively diagnosed with hyperacusis through question-naire survey.According to the scale evaluation,174 cases(59.39％)were diagnosed with hyperacusis,and the Kappa value of conformity test of the two methods was 0.81(P＜0.001).Reliability analysis indicated a Cronbach'sα coefficient of 0.93 for the entire scale.Each dimension had a Cronbach's α coefficient＞0.60.The split-half relia-bility coefficient for the entire scale was 0.86,and for each dimension,it was＞0.60.Exploratory factor analysis of validity suggested that 25 items could be grouped under 4 factors,such as functional part,social part,emotional part and harmonic sensitivity part.These factors had eigenvalues greater than 1,accounting for 59.42％of the total variance.Post-rotation,the 25 items were distributed across the 4 components,with each item having a factor load-ing＞0.40.Confirmatory factor analysis of validity showed model fit parameters as:x2/df=1.98,GFI=0.91,AGFI=0.83,CFI=0.92,TLI=0.89,RMSEA=0.08.Each item had a standardized factor loading＞0.40.Con-clusion The Chinese version of the hyperacusis scale demonstrated strong reliability and validity,making it suitable for use among the Chinese population.

Critical care medicine is a discipline dedicated to the diagnosis and treatment of severe illnesses,demanding extensive knowledge,advanced skills,and exceptional teamwork and communication abilities.However,the complexity and dynamic nature of critically ill patients often render traditional face-to-face teaching methods insufficient.Emerging educational approaches like virtual reality(VR)and augmented reality(AR)offer simulated environments,but lack the depth of interaction with the real world,constraining the educational outcomes.Mixed reality(MR),which integrates elements of both VR and AR,provides an immersive and highly interactive learning experience by seamlessly bridging the virtual and real worlds.Although MR has begun to establish itself in medical education,its application in critical care medicine remains in its early stages.This article aims to elucidate the characteristics and evolution of MR,alongside its potential value and applications in critical care medical education.
