Parkinson's disease （PD） is a neurodegenerative disorder primarily characterized by motor dysfunction. Traditionally， its main clinical features include resting tremor， muscular rigidity， bradykinesia， and postural balance disorders. However， an increasing number of studies have shown that its non-motor symptoms （NMS） exert an even greater impact on patients' quality of life than motor symptoms， severely affecting daily functioning and increasing the burden on families and society. Among these， depression is one of the most common and most debilitating NMS， with statistics indicating that the incidence of depression among PD patients reaches as high as 40%-50%. The pathological mechanisms are complex， involving the interplay between degenerative changes in dopaminergic neurons and disruptions in emotional regulatory circuits， which poses a substantial challenge to clinical treatment. Traditional Chinese medicine （TCM）， characterized by holistic regulation and multi-target intervention， has demonstrated significant advantages in the treatment of PD and depression， offering new insights for managing PD-depression comorbidity. This study integrates research extracted from multiple databases， including PubMed， Web of Science， Google Scholar， and China National Knowledge Infrastructure （CNKI）， that investigates the potential mechanisms of PD and depression as well as TCM-based treatments for these conditions. The aim is to elucidate the shared pathological mechanisms underlying PD and depression and to explore the therapeutic potential of TCM in effectively combating PD-depression comorbidity through these shared mechanisms， thereby providing valuable insights for the development of targeted therapies.

OBJECTIVE To investigate the vasodilatory effect of dimethyl sulfoxide(DMSO)on isolated aortic arteries and intrarenal arteries of rats and the mechanisms.METHODS ① Rat aortas and intrarenal arteries were pre-contracted with KCl 60 mmol·L-1,U46619 0.3 μmol·L-1 or PE 3 μmol·L-1.Following equilibration,dimethyl sulfoxide(DMSO)was cumulatively administered at concentrations of 0.1%,0.3%,1.0%,3.0%and 10.0%.Changes in the vascular tension of aortic and intrarenal arterial rings were recorded using an isolated vessel tension measurement system.Rat intrarenal arteries were pre-contracted with KCl 60 mmol·L-1,U46619 0.3 μmol·L-1 or PE 3 μmol·L-1.Cumulative additions of DMSO(3.0%and 10.0%)were administered as the control group.Following pre-contraction with each of the three stimulants,the voltage-gated potassium channel(Kv)inhibitor 4-AP(0.5 mmol·L-1)was incubated for 15 min.Cumulative additions of DMSO(3.0%and 10.0%)were then administered,and the vascular relaxation percentages induced by DMSO before and after treatment were calculated.Whole-cell patch-clamp recordings were performed on acutely isolated intrarenal arterial smooth muscle cells of rat to assess Kv currents during cumulative DMSO applications(0.1%,0.3%,1.0%and 3.0%).② Rat aortic smooth muscle cells(A7r5)were exposed to DMSO concentration of 0.0%(control),0.1%,0.3%,1.0%and 3.0%for 24 h.Intracellular reactive oxygen species(ROS)levels were detected using the DCFH-DA fluorescent probe.Malondialdehyde(MDA)content,catalase(CAT)activity,and superoxide dismutase(SOD)activity in A7r5 cells were measured by chemical colorimetry.Mitochondrial membrane potential was evaluated using the JC-1 fluorescent probe.RESULTS ① DMSO(0.1%-10.0%)dose-dependently relaxed rats aortic and intrarenal arteries pre-contracted with either KCl 60 mmol·L-1,U46619 0.3 μmol·L-1 or PE 3 μmol·L-1.The values of maximum relaxation were(42.3±9.7)%,(73.2±8.4)%,(99.2±4.7)%and(84.0±1.9)%,(80.5±6.1)%and(81.2±4.4)%,respectively.Compared with the control group,vasorelaxation of DMSO on IRAs precontracted with U46619 was significantly attenuated by Kv inhibitor 4-AP.② Low concentrations(0.1%and 0.3%)of DMSO significantly increased Kv currents,while high concentrations(1.0%and 3.0%)of DMSO significantly decreased Kv currents.High concentrations(1.0%and 3.0%)of DMSO remarkablely increased ROS and MDA levels,but significantly decreased CAT activity,SOD activity and mitochondrial membrane potential in A7r5 cells.CONCLUSION DMSO(0.1%-10.0%)can relax rats aortal and intrarenal arteries in a concentra-tion-dependent manner,and the mechanism may be related to Kv,oxidative stress and mitochondrial damage.

Objective:To develop the Nurse Parenting Stress Scale and evaluate its reliability and validity.Methods:Based on Abidin's Parenting Stress Theory, scale items were generated through literature review and semi-structured interviews. The initial version was constructed via Delphi expert consultation. Using a convenience sampling method, nurses from six hospitals in Shandong Province were surveyed between August and October 2024. The first survey collected 314 questionnaires (308 valid, effective recovery rate 98.1%) for item analysis and exploratory factor analysis (EFA). The second survey collected 458 questionnaires (447 valid, effective recovery rate 97.6%) for confirmatory factor analysis (CFA) .Results:The Nurse Parenting Stress Scale consists of 4 dimensions and 31 items. The Cronbach's α coefficient of the total scale was 0.951, split-half reliability was 0.782, and test-retest reliability was 0.926. EFA extracted four common factors explaining 70.241% of the cumulative variance. CFA demonstrated a good model fit. The item-level content validity index ( I- CVI) ranged from 0.889 to 1.000, the scale-level universal agreement content validity index ( S- CVI/ UA) was 0.903, and the scale-level average content validity index ( S- CVI/ Ave) was 0.989. Conclusions:The Nurse Parenting Stress Scale shows strong reliability and validity and can serve as an effective tool for assessing parenting stress among nurses.

Objective:To retrospectively analyze the pathogenic factors of retrograde peri-implantitis (RPI) and assess the effectiveness of treatment, and to provide clinicians evidence for the prevention and treatment of RPI.Methods:A total of 2 731 patients with missing teeth (4 016 implants) who underwent implant restoration in the Department of Stomatology, The First Affiliated Hospital of Wenzhou Medical University between January 2004 and December 2022 were included in the study. According to the diagnostic criteria of RPI, a total of 20 cases (23 implants) of RPI were collected, including 4 female (5 implants) and 16 male (18 implants), and the treatment medical records, intraoral photos and cone beam CT or oral panoramic radiographs records of each patient were collected. Each patient with RPI was treated accordingly and followed up regularly to evaluate its efficacy.Results:After treatment, the follow-up time for 20 patients with clinical symptoms of RPI was 13 (6, 40) months (1 month to 13 years), and the survival rate of the treated implants was 91% (21/23). There were 7 patients (8 implants) with inactive RPI, no clinical symptoms, no loosening of the implant, with normal occlusal load, and the disease was at the inactive stage and was not treated. The pulp vitality of the natural tooth adjacent to the implant was normal, and the implant could function normally. There were 13 patients (15 implants) with infected RPI, 1 patient (1 implant) had no loosening of the implant, and the periapical radiolucency of the implant disappeared after endodontic treatment of the natural tooth adjacent to the implant; 12 patients (14 implants) had clinical symptoms such as implant loosening, pus discharge, etc. Among them, 10 patients (12 implants) were successfully implanted in situ or in adjacent sites after removing the implants, and were successfully implanted after 3 to 20 months. Two patients(2 implants) were removed and no further implants were placed. Among them, 2 implants with infected RPI had cystic lesions, which was similar to natural root apex cysts.Conclusions:The etiology of RPI is related to inflammation of adjacent tooth root tips or bacterial residues from inflammatory lesions in the alveolar bone and bone augmentation. RPI can be treated by perfect root canal treatment of adjacent teeth, removal of inflammatory tissue, or simultaneous guided bone regeneration techniques.

Dyslipidemia refers to the increased level of TG and total cholesterol in plasma, and also generally refers to other forms of dyslipidemia, which is characterized by non-obvious symptoms in the early stage of the disease, and the first episode is cardiovascular disease. The prevalence of dyslipidemia varies with country, region and population, and the prevalence of dyslipidemia in China is in increase, which is influenced by various risk factors. This paper summarizes the prevalence and risk factors of dyslipidemia and introduces the emerging risk factors of dyslipidemia, such as HIV infection, systemic lupus erythematosus, sarcopenia and environmental problem.

After ostomy surgery, patients lose the ability to control their anal sphincter, relying on ostomy pouches for excretion. Convex baseplates offer several advantages, including preventing leakage, reducing the risk of stoma and peripheral skin complications, and adapting to the dynamic stoma shapes caused by peristaltic expansion and contraction of the stoma. This article reviews the structure and features of convex baseplates, usage considerations, existing challenges, and future prospects, aiming to provide a reference for the standardized clinical use of convex baseplates and to improve patient health outcomes.
