Objective: To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes. Methods: The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model. Results: A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915). Conclusion The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

OBJECTIVE To optimize the stir-frying process of Platycodon grandiflorum， compare the protective effect of P. grandiflorum on lung injury in mice before and after stir-frying， and preliminarily explore the characteristics of “enhanced efficacy through processing” of stir-frying P. grandiflorum. METHODS On the basis of single-factor experiment， the stir-frying time， temperature and frequency were taken as factors， and the comprehensive scores of appearance traits， platycodin D content and alcohol extract content were taken as indexes. Box-Behnken response surface experiment was designed to optimize the stir-frying process of P. grandiflorum and verify it. The mice were divided into blank control group， model group， dexamethasone group （positive control drug， 5 mg/kg）， P. grandiflorum low-dose and high-dose groups （0.6，1.2 g/kg）， fried P. grandiflorum low and high dose groups （0.6， 1.2 g/kg）， with 8 mice in each group. The treatment was given once a day for 10 consecutive days. After the last administration， acute lung injury model was established by intratracheal instillation of lipopolysaccharide. The levels of interleukin-6 （IL-6）， IL-1β， tumor necrosis factor-α （TNF-α） in serum and superoxide dismutase （SOD）， myeloperoxidase （MPO） and malondialdehyde （MDA） in lung tissue were detected， lung wet/dry weight ratio and thymus index were calculated， and the pathological changes of lung tissue were observed. RESULTS The optimum processing conditions were as follows：stir- frying temperature of 120 ℃， stir-frying time of 12 min， stir-frying frequency of 19 r/min； the comprehensive scores of the three batches of process verification were all greater than 97 points， RSD＜3% （n＝3）. The results of pharmacodynamic experiments showed that compared with blank control group， the lung dry-wet weight ratio as well as the levels of IL-6， IL-1β， TNF-α， MPO and MDA in the model group were significantly increased （P＜0.01）， the thymus index and SOD level were significantly decreased （P＜0.01）， and the lung tissue was significantly damaged. Compared with model group， above indexes of the mice in each administration group were significantly improved （P＜0.01）， and the lung tissue injury was significantly reduced. At the same dose， except for the lung dry-wet weight ratio， the above indexes of the mice in the stir-fried P. grandiflorum groups were significantly improved compared with P. grandiflorum 涵。E-mail：495758271@qq.com groups （P＜0.05）， and the lung tissue damage was further reduced. CONCLUSIONS The optimized stir-frying process is stable and feasible. The protective effect of stir-fried P.grandiflorum on acute lung injury in mice is better than that of raw products at the same dosage.

Neurofibromatosis type 1 (NF1) presents with a diverse range of symptoms that can affect the skin, bones, eyes, central nervous system, and other organs. This article reports the diagnosis and treatment process of a patient with NF1 complicated by bilateral severe-to-profound sensorineural hearing loss. Genetic testing revealed a heterozygous variant of NF1 NM_ 000267.3: c.4054_ 4058del(p.Ser1352LeufsTer20, supporting the diagnosis of NF1. After thorough evaluation, a right cochlear implantation was performed, yielding satisfactory postoperative results. This case suggests that NF1 patients may exhibit phenotypic heterogeneity and atypicality, providing a reference for clinicians in the diagnosis and treatment of such patients.

Objective: To investigate the trajectories of fasting blood glucose fluctuations and their influencing factors among patients with comorbidity of type 2 diabetes mellitus (T2DM), so as to provide the basis for strengthening blood glucose management in this population. Methods: In October 2023, data of patients diagnosed with comorbid T2DM from January to October 2021, including demographic information, lifestyle, health status and fasting blood glucose were collected through the chronic disease health management system of Minhang District, Shanghai Municipality. Fasting blood glucose fluctuation trajectories were analyzed by group-based trajectory model established based on fasting blood glucose values from January 2021 to October 2023. Influencing factors of fasting blood glucose fluctuation trajectories among patients with comorbidity of T2DM were analyzed using a multinomial logistic regression model. Results: A total of 907 patients with comorbidity of T2DM were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged ≥65 years, accounting for 71.89%. The group-based trajectory model analysis identified three trajectory groups: a low-level stable group (492 cases, 54.24%), a medium-level stable group (287 cases, 31.64%), and a high-level decreasing group (128 cases, 14.11%). Multinomial logistic regression analysis showed that, compared with the low-level stable group, patients with comorbidity of T2DM who had an education level of junior high school or below (OR=1.420, 95%CI: 1.011-1.995) or college degree or above (OR=2.109, 95%CI: 1.249-3.560), as well as those who engaged in regular exercise (OR=1.387, 95%CI: 1.017-1.893), were more likely to be in the medium-level stable group. Patients with comorbidity of T2DM who were overweight or obese (OR=1.675, 95%CI: 1.116-2.513) or had dyslipidemia (OR=3.195, 95%CI: 1.642-6.216) were more likely to be in the high-level decreasing group. Conclusions From January 2021 to October 2023, the fasting blood glucose levels of patients with comorbidity of T2DM exhibited three fluctuating trajectories: low-level stability, medium-level stability, and high-level decline. Compared with the low-level stable group, the medium-level stable group was mainly influenced by educational level and regular exercise. The high-level decline group was primarily affected by overweight/obesity and dyslipidemia.

This review aimed to provide a comprehensive analysis of the etiology, epidemiology, pathology, and conventional treatment of heterotopic ossification (HO), especially emerging potential therapies. HO is the process of ectopic bone formation at non-skeletal sites. HO can be subdivided into two major forms, acquired and hereditary, with acquired HO predominating. Hereditary HO is a rare and life-threatening genetic disorder, but both acquired and hereditary form can cause severe complications, such as peripheral nerve entrapment, pressure ulcers, and disability if joint ankylosis develops, which heavily contributes to a reduced quality of life. Modalities have been proposed to treat HO, but none have emerged as the gold standard. Surgical excision remains the only effective modality; however, the optimal timing is controversial and may cause HO recurrence. Recently, potential therapeutic strategies have emerged that focus on the signaling pathways involved in HO, and small molecule inhibitors have been shown to be promising. Moreover, additional specific targets, such as small interfering RNAs (siRNAs) and non-coding RNAs, could be used to effectively block HO or develop combinatorial therapies for HO.

Retinopathy of prematurity (ROP) is a vision-threatening disorder that leads to pathological growth of the retinal vasculature due to hypoxia. Here, we investigated the potential effects of alamandine, a novel heptapeptide in the renin-angiotensin system (RAS), on hypoxia-induced retinal neovascularization and its underlying mechanisms. In vivo, the C57BL/6J mice with oxygen-induced retinopathy (OIR) were injected intravitreally with alamandine (1.0 μmol/kg per eye). In vitro, human retinal microvascular endothelial cells (HRMECs) were utilized to investigate the effects of alamandine (10 μg/mL) on proliferation, apoptosis, migration, and tubular formation under vascular endothelial growth factor (VEGF) stimulation. Single-cell RNA sequencing (scRNA-seq) matrix data from the Gene Expression Omnibus (GEO) database and RAS-related genes from the Molecular Signatures Database (MSigDB) were sourced for subsequent analyses. By integrating scRNA-seq data across multiple species, we identified that RAS-associated endothelial cell populations were highly related to retinal neovascularization. The liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis revealed a significant decrease in alamandine levels in both the serum and retina of OIR mice compared to those in the control group. Next, alamandine ameliorated hypoxia-induced retinal pathological neovascularization and physiologic revascularization in OIR mice. In vitro, alamandine effectively mitigated VEGF-induced proliferation, scratch wound healing, and tube formation of HRMECs primarily by inhibiting the hypoxia-inducible factor-1α (HIF-1α)/VEGF pathway. Further, coincubation with D-Pro⁷ (Mas-related G protein-coupled receptor D (MrgD) antagonist) hindered the beneficial impacts of alamandine on hypoxia-induced pathological angiogenesis both in vivo and in vitro. Our findings suggested that alamandine could mitigate retinal neovascularization by targeting the MrgD-mediated HIF-1α/VEGF pathway, providing a potential therapeutic agent for OIR prevention and treatment.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

ADC189 is a novel drug of cap-dependent endonuclease inhibitor. In our study, its antiviral efficacy was evaluated in vitro and in vivo, and compared with baloxavir marboxil and oseltamivir. A first-in-human phase I study in healthy volunteers included single ascending dose (SAD) and food effect (FE) parts. In the preclinical study, ADC189 showed potent antiviral activity against various types of influenza viruses, including H1N1, H3N2, influenza B virus, and highly pathogenic avian influenza, comparable to baloxavir marboxil. Additionally, ADC189 exhibited much better antiviral efficacy than oseltamivir in H1N1 infected mice. In the phase I study, ADC189 was rapidly metabolized to ADC189-I07, and its exposure increased proportionally with the dose. The terminal elimination half-life (T_1/2) ranged from 76.69 to 98.28 hours. Of note, food had no effect on the concentration, clearance, and exposure of ADC189. It was well tolerated, with few treatment-emergent adverse events (TEAEs) reported and no serious adverse events (SAEs). ADC189 demonstrated excellent antiviral efficacy both in vitro and in vivo. It was safe, well-tolerated, and had favorable pharmacokinetic characteristics in healthy volunteers, supporting its potential for single oral dosing in clinical practice.

Objective:To investigate the current status of exercise fear in patients with chronic heart failure (CHF) and explore the different potential classifications and influencing factors of exercise fear, in order to provide theoretical basis for formulating targeted interventions.Methods:The subjects of this study were 278 patients with CHF treated in the Department of Cardiology, the First Affiliated Hospital of Xinjiang Medical University from July 2023 to November 2023 using convenience sampling method. A questionnaire survey was conducted using a general information questionnaire, Fear of Activity in Patients with Chronic Heart Failure, Cardiac Exercise Self-Efficacy Instrument, Personal Support Scale From Family, and Multidimensional Fatigue Index-20. Latent profile analysis to identify potential subtypes of motor fear in patients, and unordered multiple logistic regression to evaluate the influencing factors of different subtypes were used.Results:Totally 278 valid questionnaires were collected, including 96 females and 182 males, with a majority aged between 60 and 74 years old, with 114 cases accounting for 41.0%. The 278 CHF patients had a fear of movement score of (34.78 ± 13.17) points were divided into three potential categories based on their fear of movement: low-level fear of movement group (107 cases, 38.5%), moderate fear of movement group (108 cases, 38.8%), and high-level fear of movement group (63 cases, 22.7%). Disordered multiple logistic regression analysis showed that family support level ( OR = 2.520), exercise self-efficacy ( OR = 0.913), and fatigue ( OR = 1.065) were significant influencing factors for high-level exercise fear in CHF patients (all P<0.05), while age, education level, disease course, number of coexisting diseases, family support level, exercise self-efficacy, and fatigue were significant influencing factors for high-level exercise fear in CHF patients ( OR values ranged from 0.007 to 6.292, all P<0.05). Conclusions:There are three potential categories of exercise fear in patients with CHF. Medical staff should develop targeted intervention plans based on the characteristics of different categories of patients to reduce their level of exercise fear.

Objective To explore the mechanism of ginsenoside Rg1 in alleviating heat stress-induced testicular injury in mice.Methods A total of 20 C57BL/6 male mice(6～8 weeks old)were randomly divided into 4 groups(n=5).The mice from the control group and heat stress(HS)group were intraperitoneally injected with 10 mL/(kg·d)0.9％normal saline for 14 d,while those in the HS+Rg1 group and the Rg1 group were given an intraperitoneal injection of 20 mg/(kg·d)for 14 d,and then on the 7th day after administration,the mice in the HS group and the HS+Rg1 group had the lower abdomen put into a 43 ℃ water bath for 30 min as a single heat stress after being anesthetized with 4％chloral hydrate.Mouse spermatocytes GC-2spd(ts)were divided into control group(routine culture for 48 h),HS group(placed in a 43 ℃ water bath for 30 min after 36 h of conventional culture,and cultured till the end of 48 h),HS+Rg1 group(50 μmol/L Rg1 treatment followed by heat stress injury),and Rg1 group(no heat stress injury).In 1 d after modeling,the eyeball blood samples were collected to detect serum testosterone with ELISA,and the testicles were extracted to observe the morphology and weighed to calculate the testicular index.HE staining was used to observe the histopathology of testis,and corresponding reagents and kits was employed to detect the content of malondialdehyde(MDA)and activities of catalase(CAT)and superoxide dismutase(SOD)in testis tissue.After the epididymal sperm were collected,the sperm concentration and motility were analyzed by computer-assisted sperm analysis(CASA)system.In in vitro experiments,cell apoptosis was detected with TUNEL staining,the protein levels of Nrf2,Keap1,HO-1,Bax,Bcl-2 and Caspase3 were detected with Western blotting,and the mRNA levels of GCLC,GCLM and NQO1 were detected by RT-qPCR.Results Rg1 prevented the decreases in testicular weight and testicular index caused by heat stress,reduced the damage of testicular tissue structure,prevented the decrease of sperm concentration and vitality,antagonized the decreasd number of Leydig cells and serum testosterone level,reduced the accumulation of MDA in testicular tissue,and enhanced the activities of CAT and SOD.Rg1 treatment alleviated the apoptosis of GC-2spd(ts)cells,down-regulated the expression of Bax,Caspase3 and Keap1 proteins,enhanced the expression of Bcl-2,Nrf2 and HO-1 proteins,and increased the transcriptional levels of Nrf2 target genes GCLC,GCLM and NQO1.Conclusion Rg1 has no significant effect on the structure and function of mouse testes,but it can effectively improve the ability of mouse testes to resist heat stress injury,which may be related to the activation of Nrf2 signaling pathway,the improvement of antioxidant enzyme activity,and the reduction of apoptosis of spermatogenic cells.
