BackgroundIndividuals with chronic multimorbidity exhibit a high prevalence of sleep disturbances， which impair their physical and psychological well-being and impede chronic disease management. Although sleep quality is closely influencing with psychological functioning， empirical evidence regarding the longitudinal trajectories of sleep quality and their influencing factors in this population remains insufficient. ObjectiveTo investigate the longitudinal trajectories of sleep quality and associated factors among patients with chronic multimorbidity from hospitalization through 6 months post-discharge， aiming to facilitate the early identification of high-risk individuals and the development of personalized sleep interventions. MethodsA total of 228 inpatients with chronic multimorbidity， primarily with cardiovascular and metabolic chronic conditions， were enrolled via random sampling at The Third People's Hospital of Fuyang from January 2023 to September 2024. Baseline assessments were conducted during hospitalization using the general socio-demographic questionnaire， the Sleep Dysfunction Rating Scale （SDRS）， the Ruminative Response Scale （RRS）， and the Hospital Anxiety and Depression Scale （HADS）. Sleep quality was further evaluated using the SDRS at 1-， 3-， and 6-month post-discharge. Latent class growth model was employed to delineate trajectories of sleep quality. Multivariate logistic regression analysis was subsequently performed to identify influencing factors of sleep quality. ResultsA total of 201 patients with chronic diseases were included.Based on four predefined assessment time points （baseline， 1 month， 3 months， 6 months post-discharge）， the latent class growth model identified three distinct trajectories of sleep quality： persistent high sleep disturbance （n=72， 35.82%）， moderate sleep disturbance-progression （n=73， 36.32%）， and low sleep disturbance （n=56， 27.86%）. Multivariate logistic regression analysis revealed that， compared with the low sleep disturbance group， multiple factors increased the odds of membership in the persistent high sleep disturbance group： per capita monthly household income of <3 000 yuan （β=13.131， P<0.01） or 3 000–5 000 yuan （β=5.913， P<0.05）， aged 45–65 years （β=9.536， P<0.05）， presence of 3 （β=7.792， P<0.05） or >3 comorbid chronic conditions （β=6.626， P<0.05）， as well as higher RRS （β=0.334， P<0.01） and HADS score （β=1.628， P<0.01）. Additionally， patients aged 45–65 years （β=2.777， P<0.05）， with 3 （β=3.802， P<0.01） or >3 comorbid chronic conditions （β=2.463， P<0.01）， and with higher RRS （β=0.111， P<0.01） and HDAS scores （β=0.350， P<0.05） also demonstrated significantly increased odds of belonging to the moderate sleep disturbance–progression group. ConclusionThere is significant population heterogeneity in sleep quality trajectories among patients with chronic multimorbidity， with age， per capita household monthly income， number of comorbidities， rumination， and anxiety/depression symptoms being identify as the primary influencing factors.

Objective: To investigate the antibody testing demand and its influencing factors among college students in Shaoxing City Zheijiang Province, so as to provide evidence for carrying out HIV antibody testing services for college students. Methods: From November to December 2022, stratified cluster random sampling method was used to survey college students from 13 colleges in Shaoxing City. Data on socio-demographic information, demand for HIV antibody testing, sexual behaviors, and HIV-related knowledge were collected through a self - designed questionnaire. Factors affecting HIV antibody demand among college students were analyzed using a multivariable logistic regression model. Results: A total of 43 716 college students were surveyed, including 19 471 males (44.54%) and 24 245 females (55.46%). There were 2 004 college students (4.58%) with HIV antibody testing demand. Multivariable logistic regression analysis showed that female students (OR=1.344, 95%CI: 1.217-1.485), those in undergraduate institutions (OR=1.296, 95%CI: 1.168-1.438), homosexuals (OR=1.742, 95%CI: 1.301-2.333) or bisexual/uncertain (OR=1.342, 95%CI: 1.171-1.537), those who had sexual experience (OR=1.416, 95%CI: 1.210-1.657), those who had sex with men in the past 6 months (OR=2.164, 95%CI: 1.405-3.333), those who received HIV testing promotion at school in the past year (OR=1.500, 95%CI: 1.327-1.695), and those with perceived risk of HIV infection (OR=5.875, 95%CI: 5.336-6.468) had greater HIV antibody testing demand. Conclusions The HIV testing demand among college students is associated with gender, school type, sexual orientation, sexual behaviors, HIV testing promotion, and perceived risk of HIV infection. It is recommended to strengthen HIV knowledge dissemination of AIDS knowledge and mobilization for HIV antibody testing in colleges to improve the accessibility of HIV antibody testing services.

The core pathogenesis of disease caused by latent toxin is deficiency of healthy qi and lingering pathogen, which is characterized by lingering and recurrent courses, and onset upon exogenous induction. The biological mechanisms of disease caused by latent toxin present multi-dimensional and synergistic characteristics. Immune dysfunction and inflammatory response serve as the core links, involving the abnormal activation of signaling pathways such as Wnt/β-catenin, PI3K/Akt/mTOR, TLR, and NF-κB; the accumulation of metabolites, as the microscopic carrier of latent toxin, participates in chronic complications of diabetes by damaging vascular endothelium and inhibiting repair pathways; immune escape and tolerance, as well as weakened tumor suppressor function, supplement the potential mechanisms of latent toxin from the perspectives of pathogen/tumor cell latency and congenital insufficiency; the imbalance of tissue repair and remodeling, and the imbalance of protein metabolism and cellular homeostasis further improve the mechanism network of latent toxin. Among these, immune dysfunction, tumor suppressor gene mutation, and regulatory dysfunction may be the microscopic manifestations of "healthy qi deficiency"; inflammatory factors, metabolites, viruses, and tumor cells may be the microscopic manifestations of "latent toxin". Current studies have limitations, such as unclear specific biomarkers for different types of latent toxin, insufficient research on the interaction of multiple mechanisms, and lack of clinical verification. It is suggested that future research should be further carried out around "latent toxin classification-mechanism-efficacy".

Introduction::The triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, a novel biomarker for metabolic syndrome (MetS), has been validated in the general population as being significantly correlated with cardiovascular disease (CVD) risk. However, its capabilities to predict CVD in people living with human immunodeficiency virus (HIV; PLWH) remain underexplored.Methods::We conducted a retrospective cohort study of 16,081 PLWH who initiated antiretroviral therapy (ART) at the Third People’s Hospital of Shenzhen (China) from 2005 to 2022. The baseline TG/HDL-C ratio was calculated as TG (mmol/L) divided by HDL-C (mmol/L). We employed a multivariate Cox proportional hazards model to assess the association between the TG/HDL-C ratio and CVD occurrence, using Kaplan-Meier curves and log-rank tests to compare survival distributions. The increase in prediction risk upon the addition of the biomarker to the conventional risk model was examined through the assessment of changes in net reclassification improvement (NRI) and integrated discrimination improvement (IDI). Nonlinear relationships were investigated using a restricted cubic spline plot, complemented by a two-piecewise Cox proportional hazards model to analyze threshold effects.Results::At the median follow-up of 70 months, 213 PLWH developed CVD. Kaplan-Meier curves demonstrated a significant association between the increased risk of CVD and a higher TG/HDL-C ratio (log-rank P <0.001). The multivariate-adjusted Cox proportional hazards regression model indicated that the CVD hazard ratios (HR) (95% confidence intervals [95% CIs]) for Q2, Q3, and Q4 versus Q1 of the TG/HDL-C ratio were 2.07 (1.24, 3.45), 2.17 (1.32, 3.57), and 2.20 (1.35, 3.58), respectively ( P <0.05). The consideration of the TG/HDL-C ratio in the model, which included all significant factors for CVD incidence, improved the predictive risk, as indicated by the reclassification metrics (NRI 16.43%, 95% CI 3.35%-29.52%, P = 0.014). The restriction cubic spline plot demonstrated an upward trend between the TG/HDL-C ratio and the CVD occurrence ( P for nonlinear association = 0.027, P for overall significance = 0.009), with the threshold at 1.013. Significantly positive correlations between the TG/HDL-C ratio and CVD were observed below the TG/HDL-C ratio threshold with HR 5.88 (95% CI 1.58-21.88, P = 0.008), but not above the threshold with HR 1.01 (95% CI 0.88-1.15, P = 0.880). Conclusion::Our study confirms the effectiveness of the TG/HDL-C ratio as a predictor of CVD risk in PLWH, which demonstrates a significant nonlinear association. These findings indicate the potential of the TG/HDL-C ratio in facilitating early prevention and treatment strategies for CVD among PLWH.

Objective To evaluate safety and efficacy of linaclotide combined with polyethylene glycol(PEG)for bowel preparation.Methods A total of 612 patients from Department of Gastroenterology at the Affiliated Hospital of Qingdao University for colonoscopy examination from January to June 2023 were selected.They were divided into group 1(1 L PEG+2 L PEG),group 2(linaclotide+2 L PEG)and group 3(1 L PEG+linaclotide+1 L PEG)by random number table method,with 204 cases in each group.The Ottawa Bowel Preparation Quality Scale(OBPS),the insertion time of colonoscopy,the time of the first defecation,the frequency of defecations,the occurrence of adverse effects and patients'tolerability were compared among the three groups.Results A total of 601 patients completed bowel preparation and accepted colonoscopy.Group 1 exhibited no statistically significant differences to group 2 with regards to OBPS and insertion time.However,Group 2 demonstrated a shorter duration for the time of the first defecation in comparison to both group 1 and group 3(P＜0.05).Group 1 displayed a higher frequency of defecations as compared to Group 2 and Group 3(P＜0.05).The incidence of adverse reactions was significantly lower in group 2 and group 3 than in group 1(P＜0.05).The overall tolerance score of patients in group 1 was low-er than that in group 2 and group 3(P＜0.05).Conclusions The effect of combining 2 L PEG with 290 μg of lina-clotide for bowel preparation before colonoscopy is similar to that of 3 L PEG.It can reduce the incidence of adverse reactions and patients exhibit good tolerance.For patients who are intolerant to a single high-dose administration of PEG,they need divided-dose regimen of 2 L PEG in combination with linaclotide.

Objective:To summarize the clinical characteristics of patients with epilepsy caused by focal cortical dysplasia (FCD), and identify the influencing factors for postoperative seizure controls.Methods:Fifty-seven patients with epilepsy caused by FCD admitted to Department of Neurosurgery, Third Affiliated Hospital of Zhengzhou University from July 2019 to November 2023 were chosen; standard preoperative evaluation, surgery, postoperative management and follow-up were performed. A retrospective study of clinical data, imaging and video electroencephalogram (VEEG) data, surgical approaches, pathological findings, and follow-up data was performed; influencing factors for postoperative seizure controls were analyzed.Results:In these 57 patients with epilepsy caused by FCD, 29 were males (50.88%) and 28 were females (49.12%). Onset age was 30.00 (8.00, 74.50) months, and surgery age was 95.00 (50.00, 138.50) months. Focal to bilateral tonic-clonic seizures (42/57; 73.68%) and epileptic spasms (13/57; 22.81%) were common seizure types. Cranial MRI was positive in 34 patients (59.65%), mainly manifested as abnormal cortical gyri/sulci morphology (17/57; 29.82%). In 43 patients accepted PET-CT, hypometabolic sites were detected in 40 (93.02%), and complete agreement between PET/MRI fusion results and actual lesion sites was noted in 40 (93.02%). FCD type I was noted in 16 patients (28.07%), type II in 39 (68.42%), and type III in 2 (3.51%). By December 2023, 44 (77.19%) had Engel grading I, 4 (7.02%) had grading II, 4 (7.02%) had grading III, and 5 (8.77%) had grading IV. Children with good prognosis (Engel grading I+II) and those with poor prognosis (Engel grading III+IV) showed significant differences in terms of time from first seizure to surgery, positive/negative MRI, and regularity of postoperative ASMs ( P<0.05). Conclusions:Focal to bilateral tonic-clonic seizure is the most common seizure type in patients with epilepsy caused by FCD, and abnormal cortical gyri/sulci morphology is the most common MRI manifestation; PET/MRI fusion imaging is superior to PET-CT or MRI in identifying epileptogenic foci. Poor seizure control can be noted in patients with long onset time to surgery, with negative cranial MRI results, or with irregular postoperative ASMs.

Objective:To investigate the effect of mid-ventricular obstruction (MVO) on left ventricular systolic function in patients with hypertrophic cardiomyopathy(HCM) by four-dimensional automatic left ventricular quantitation technology(4D Auto LVQ).Methods:Fifty-seven hypertrophic obstructive cardiomyopathy patients were selected from December 2020 to October 2022 in the First Affiliated Hospital of Zhengzhou University. According to the presence of MVO, HCM patients were divided into two groups: HCM 1 group, HCM without MVO ( n=34); HCM 2 group, HCM with MVO ( n=23). In addition, 25 healthy subjects in the same period were selected as the control group. Conventional ultrasound parameters were collected, and 4D Auto LVQ technology was used to obtain the mechanical parameters of left ventricular myocardium, including left ventricular longitudinal strain (GLS), circumferential strain (GCS), area strain (GAS), radial strain (GRS), segmental longitudinal strain (SLS) and area strain (SAS). The differences of these parameters among the three groups were compared. Results:①Compared with the control group, the thickness of the maximum basal segment of interventricular septum, the thickness of the middle segment of the maximum interventricular septum, the thickness of the apical segment of the interventricular septum, the thickness of the left ventricular posterior wall and left atrium diameter were significantly increased. Six-minute walk distance and the left ventricular end-diastolic diameter was decreased in the two groups of HCM(all P<0.05). Left ventricular outflow tract gradients in HCM 1 group was higher than HCM 2 group( P<0.05), but there was no significant difference in left ventricular ejection fraction among the three groups( P>0.05). There was significant difference in the incidence of left ventricular apical aneurysm among the three groups( P<0.05). ②Compared with the control group, the GLS in both HCM groups was lower, and it was lower in the HCM 2 group than in the HCM 1 group(all P<0.05) the GRS and GAS in both HCM groups were lower than in the control group ( P<0.05), and there was no significant difference between the two groups of HCM, and there was no significant difference in GCS among the three groups(all P>0.05). ③Compared with the control group, the SLS of basal segment, middle segment, apical cap, posterior septum, inferior wall and lateral wall in HCM group were significantly lower than those in control group. The SLS of apical segment of posterior septum, anterior septum, anterior wall, posterior wall, inferior wall and apical segment of posterior septum, lateral wall and inferior wall in HCM 2 group were significantly lower than HCM 1 group(all P<0.05), but there was no significant difference in SLS of posterior septum, anterior septum, anterior wall, lateral wall and inferior wall between the two groups(all P>0.05). ④Compared with the control group, the SAS of posterior septal basal segment, middle segment, anterior septal middle segment, anterior wall basal segment, middle segment, apical segment, lateral wall basal segment, middle segment, apical segment, posterior wall basal segment, middle segment, inferior wall basal segment, middle segment and apical cap in HCM groups were significantly lower than the control group(all P<0.05), but there was no significant difference in SAS between the two groups of HCM( P>0.05). Conclusions:4D Auto LVQ can quantitatively evaluate the damage of MVO on the left ventricular systolic function in patients with HCM, especially for the evaluation of local myocardial function damage in the medial segment and apical segment.

Percutaneous coronary intervention(PCI)is one of the most important therapeutic measures for coronary heart disease.It can quickly and effectively relieve coronary artery obstruction.Patients with coronary heart disease often suffer from the complication of emotional disorders like anxiety and depression.The incidence of anxiety and depression in patients having undergone PCI is significantly higher in those having not.But anxiety and depression can remarkably increase the major adverse cardiac events(MACE)in patients after PCI.This article reviews the associations,mechanisms and treatments of anxiety and depression after PCI.
