Platelet lipid rafts are dynamic nanodomains enriched in cholesterol and sphingolipids within the plasma membrane. As pivotal hubs for signal transduction, membrane trafficking, and intercellular interactions, they have garnered significant attention in recent years for their roles in regulating platelet function and related disease mechanisms. This article reviews the structural characteristics and molecular composition of platelet lipid rafts, as well as their central roles in signal transduction and cytoskeletal reorganization. It particularly focuses on the functional abnormalities and pathological contributions of lipid rafts in diseases such as atherosclerosis, antiphospholipid antibody syndrome, and ANCA-associated vasculitis. Research indicates that lipid rafts coordinate platelet activation, inflammatory responses, and immunomodulatory processes by integrating receptor clustering, enrichment of signaling proteins, and regulation of metabolites. Finally, the article discusses the future prospects of lipid raft-targeted nanotherapeutic strategies and addresses challenges in translational research, providing a theoretical foundation and novel perspectives for understanding platelet biology and intervening in thrombo-inflammatory diseases.

Background and objective Current studies suggest that for early-stage lung cancers with a component of ground-glass opacity measuring ≤2 cm,sublobar resection is suitable if it ensures adequate margins.However,lobectomy may be necessary for some cases to achieve this.The aim of this study was to explore the impact of size and depth on surgical techniques for wedge resection,segmentectomy,and lobectomy in early-stage lung cancer ≤2 cm,and to determine methods for ensuring a safe resection margin during sublobar resections.Methods Clinical data from 385 patients with early-stage lung can-cer ≤2 cm,who underwent lung resection in 2022,were subject to a retrospective analysis,covering three types of procedures:wedge resection,segmentectomy and lobectomy.The depth indicator as the OA value,which is the shortest distance from the inner edge of a pulmonary nodule to the opening of the corresponding bronchus,and the AB value,which is the distance from the inner edge of the nodule to the pleura,were measured.For cases undergoing lobectomy and segmentectomy,three-dimensional computed tomography bronchography and angiography(3D-CTBA)was performed to statistically determine the number of subsegments required for segmentectomy.The cutting margin width for wedge resection and segmentectomy was recorded,as well as the specific subsegments and their quantities removed during lung segmentectomy were documented.Results In wedge resection,segmentectomy,and lobectomy,the sizes of pulmonary nodules were(1.08±0.29)cm,(1.31±0.34)cm and(1.50±0.35)cm,respectively,while the depth of the nodules(OA values)was 6.05(5.26,6.85)cm,4.43(3.27,5.43)cm and 3.04(1.80,4.18)cm for each procedure,showing a progressive increasing trend(P＜0.001).The median resec-tion margin width obtained from segmentectomy was 2.50(1.50,3.00)cm,significantly greater than the 1.50(1.15,2.00)cm from wedge resection(P＜0.001).In wedge resections,cases where AB value＞2 cm demonstrated a higher proportion of cases with resection margins less than 2 cm compared to those with margins greater than 2 cm(29.03％vs 12.90％,P=0.019).When utilizing the size of the nodule as the criterion for resection margin,the instances with AB value＞2 cm continued to show a higher proportion in the ratio of margin distance to tumor size less than 1(37.50％vs 17.39％,P=0.009).The median number of subsegments for segmentectomy was three,whereas lobectomy cases requiring segmentectomy involved five subsegments(P＜0.001).Conclusion The selection of the surgical approach for lung resection is influenced by both the size and depth of pulmonary nodules.This study first confirms that larger portions of lung tissue must be removed for nodules that are deeper and larger to achieve a safe margin.A distance of ≤2 cm from the inner edge of the pulmonary nodule to the nearest pleura may be the ideal indication for performing wedge resection.

Objective To discuss the effect of multidisciplinary family empowerment mode in home care for patients after receiving percutaneous endoscopic gastrostomy(PEG).Methods A total of 86 patients,who received initial PEG at the Jilin Provincial Cancer Hospital of China from January 2021 to July 2023,were selected for this study.The patients were randomly divided into observation group.The patients of the control group received routine nursing guidance for gastrostomy,while the patients of the observation group received multidisciplinary family empowerment nursing mode.The self-care ability[using self-care ability scale of the elderly(SASE)score],health behavior ability[using self-rating scale of health behavior ability(SRAHP)score],incidence of complications,and healing time of complications were compared between the two groups.Results In the observation group the SASE[(129.48±5.48)points vs.(73.05±12.04)points]and the SRAHP[(80.14±1.00)points vs.(70.25±7.92)points]were significantly higher than those in the control group(all P＜0.05),the incidence of complications was lower than that in the control group,and the healing time of complications was shorter than that in the control group.Conclusion The implementation of multidisciplinary family empowerment nursing mode can improve the self-care ability and health behavior ability of patients after receiving PEG,reduce postoperative complications,as well as shorten the healing time of complications,therefore,this nursing mode is suitable for home patients after receiving PEG.

Objective:To explore the feasibility of constructing an objective tinnitus subtype model based on peripheral blood differentially expressed genes (DEGs) using a combination of Weighted Gene Co-expression Network Analysis (WGCNA) and Random Forest algorithm (RF).Methods:From October 2019 to June 2020, peripheral blood DEGs were obtained from 37 patients (from the Third Affiliated Hospital of Sun Yat-sen University)with chronic subjective high-frequency tinnitus (21 unbothersome type, 16 bothersome type) and 20 healthy volunteers through high-throughput sequencing. WGCNA was used to construct gene modules with different expression patterns and analyze their relationships with tinnitus characteristics. Subsequently, RF was employed to build subtype models, which were evaluated by the area under the receiver operating characteristic curve (AUC), accuracy, and F1-score.Results:A total of 12 351 intergroup DEGs were divided into 9 gene modules. Among them, MEblue, MEgreen, and MEbrown showed significant negative correlations with the healthy volunteer group, while MEpink showed a significant positive correlation with the tinnitus distress group. The "Tinnitus vs. Normal" and "Compensatory vs. Decompensatory" subtype models, based on MEblue and MEpink respectively, both had AUCs greater than 0.80, accuracies above 90%, and F1-scores above 0.90, indicating good performance.Conclusions:Peripheral blood DEGs are potential biological indicators for objective classification of subjective tinnitus. The combined application of WGCNA and the Random Forest algorithm should be a viable approach to constructing an objective tinnitus subtype model. However, further exploration and refinement are needed to validate the model′s generalizability, cross-dataset performance, and algorithm optimization.

ObjectiveTo compare the effect of toe-spread-out exercises (TSO) and modified TSO in females with hallux valgus. MethodsFrom September to December, 2023, a total of 45 females with hallux valgus were recruited in Capital University of Physical Education and Sports and randomly divided into blank control group (n = 15), TSO group (n = 15), and modified TSO group (n = 15). The blank control group received no intervention, the TSO group received routine TSO, and the modified TSO group received fibularis longus fascia release followed by TSO, for eight weeks. Changes in the hallux valgus angle (HVA) and the cross-sectional area (CSA) of the abductor hallucis muscle were measured before intervention, and four and eight weeks after intervention, respectively. ResultsOne case dropped out from the blank control group. The changes of HVA in the TSO and modified TSO groups were significantly greater than in the blank control group (F > 15.263, P < 0.05). After four weeks of intervention, the change of left HVA in the modified TSO group was significantly greater than in the TSO group (P < 0.05). The main effect of time was significant on the CSA of the abductor hallucis muscle (F > 13.245, P < 0.05). The main effect of group was significant on the left foot's CSA of the abductor hallucis (F = 3.798, P < 0.05). The interaction effect of time and group was also significant (F > 4.744, P < 0.05). The CSA of the abductor hallucis in both the TSO and modified TSO groups after four weeks and eight weeks of intervention was significantly greater than before intervention (P < 0.05). At eight weeks, the CSA of the right foot in the modified TSO group was significantly greater than in the blank control group (P < 0.05). ConclusionBoth TSO and modified TSO can improve HVA and the CSA of the abductor hallucis muscle in females with hallux valgus, and modified TSO is better.

Cardiovascular diseases (CVDs) are the most common cardiovascular system disorders. Cellular senescence is a key mechanism associated with dysfunction of aged vascular endothelium. Hyaluronic acid and proteoglycan link protein 1 (HAPLN1) has been known to non-covalently link hyaluronic acid (HA) and proteoglycans (PGs), and forms and stabilizes HAPLN1-containing aggregates as a major component of extracellular matrix. Our previous study showed that serum levels of HAPLN1 decrease with aging. Here, we found that the HAPLN1 gene expression was reduced in senescent human umbilical vein endothelial cells (HUVECs). Moreover, a recombinant human HAPLN1 (rhHAPLN1) decreased the activity of senescence-associated β-gal and inhibited the production of senescence-associated secretory phenotypes, including IL-1β, CCL2, and IL-6. rhHAPLN1 also downregulated IL-17A levels, which is known to play a key role in vascular endothelial senescence. In addition, rhHAPLN1 protected senescent HUVECs from oxidative stress by reducing cellular reactive oxygen species levels, thus promoting the function and survival of HUVECs and leading to cellular proliferation, migration, and angiogenesis. We also found that rhHAPLN1 not only increases the sirtuin 1 (SIRT1) levels, but also reduces the cellular senescence markers levels, such as p53, p21, and p16. Taken together, our data indicate that rhHAPLN1 delays or inhibits the endothelial senescence induced by various aging factors, such as replicative, IL-17A, and oxidative stress-induced senescence, thus suggesting that rhHAPLN1 may be a promising therapeutic for CVD and atherosclerosis.

Hair loss is a common condition that can have a negative impact on an individual’s quality of life. The severe side effects and the low efficacy of current hair loss medications create unmet needs in the field of hair loss treatment. Hyaluronan and Proteoglycan Link Protein 1 (HAPLN1), one of the components of the extracellular matrix, has been shown to play a role in maintaining its integrity. HAPLN1 was examined for its ability to impact hair growth with less side effects than existing hair loss treatments. HAPLN1 was predominantly expressed in the anagen phase in three stages of the hair growth cycle in mice and promotes the proliferation of human hair matrix cells. Also, recombinant human HAPLN1 (rhHAPLN1) was shown to selectively increase the levels of transforming growth factor-β receptor II in human hair matrix cells. Furthermore, we observed concomitant activation of the ERK1/2 signaling pathway following treatment with rhHAPLN1. Our results indicate that rhHAPLN1 elicits its cell proliferation effect via the TGF-β2-induced ERK1/2 pathway. The prompt entering of the hair follicles into the anagen phase was observed in the rhHAPLN1-treated group, compared to the vehicle-treated group. Insights into the mechanism underlying such hair growth effects of HAPLN1 will provide a novel potential strategy for treating hair loss with much lower side effects than the current treatments.

Objective:To explore the protective effect of Shen’an decoction on cisplatin induced renal injury in rats by regulating TLR4/NF-κB signaling pathway. Methods:Sixty SD rats were randomly divided into blank group, model group, positive control group, high dose Shen’an Decoction group, medium dose Shen’an Decoction group and low dose Shen’an Decoction group, with 10 rats in each group. Except the blank group, the other groups were intraperitoneally injected with cisplatin 7.5 mg/kg to prepare the acute kidney injured rat model. After the modeling, the high, medium and low dose groups of Shen’an Decoction were gavaged with 0.698, 1.395 and 2.790 g/ml Shen’an Decoction respectively, and the positive control group was gavaged with benazepril hydrochloride suspension of 5 mg/kg, once a day for 14 days. The kidney histopathological changes of rats in each group were observed by HE staining. The content of BUN, creatinine(CR), Cystatin C (Cys-C), TNF-α, and IL-6 in serum were detected by ELISA. The expression of TLR-4, NF-κB p65, myeloid differentiation factor (MyD88), and tumor necrosis factor receptor related factor 6 (TRAF-6) in renal tissue were detected by Western blot. Results:Compared with the model group, the growth condition of rats in each dose group of Shen’an Decoction was significantly improved ( P<0.05), and the kidney coefficient was significantly decreased ( P<0.05). The serum levels of BUN, Cr, Cys-C, TNF-α, IL-6 of rats in each dose group of Shen’an Decoction were significantly decreased ( P<0.05). The expression of TLR-4 (0.54 ± 0.07, 0.52 ± 0.09, 0.41 ± 0.04 vs. 0.86 ± 0.06), NF-κB (0.74 ± 0.02, 0.72 ± 0.06, 0.67 ± 0.05 vs. 0.93 ± 0.03), MyD88 (0.86 ± 0.02, 0.82 ± 0.03, 0.61 ± 0.02 vs. 1.04 ± 0.03), and TRAF-6 (0.65 ± 0.04, 0.58 ± 0.08, 0.54 ± 0.07 vs. 0.90 ± 0.06) in kidney tissue of rats in each dose group of Shen’an Decoction was significantly decreased ( P<0.05). Conclusion:Shen’an Decoction can protect the renal function of rats by inhibiting TLR4/NF-κB signaling pathway and alleviating the pathological changes of renal injury induced by cisplatin.

OBJECTIVES: To understand the psychological status of the staff in a general hospital during the coronavirus disease 2019 and its influential factors, and to provide references for the mental health services to hospital staff. METHODS: Using star platform of questionnaire, the staff in the general hospital were investigated via Depression, Anxiety, Stress Scale (DASS-21), Social Support Rating Scale (SSRS) and Simplified Coping Style Questionnaire (SCSQ). The influential factors were discussed by descriptive analysis, rank sum test, single factor analysis, correlation analysis and multiple factors binary logistic regression analysis. RESULTS: A total of 2 060 valid questionnaires were collected. The negative emotions of nurses and cleaners were the most obvious. The depression scores, anxiety scores and stress scores for nurses and cleaners were 5.06±7.47, 6.36±7.84, 9.75±8.65, and 6.72±8.84, 4.51±6.56, 9.69±9.56, respectively. Multivariate binary logistic regression analysis showed that staff types, education levels, job status, economic situation and concerns on the supplies of protective goods were the main influential factors for depression; staff types, contacting status with infected patients, economic situation, concerns on the supplies of protective goods, history of disease were the main influential factors for anxiety; contacting status with infected patients, economic situation, concerns on the supplies of protective goods were the main influential factors for stress. CONCLUSIONS There are differences in psychological characteristics among different groups of staff in the general hospital under the outbreak. Thus psychological protection and intervention measures should be formulated according to different groups and work status.

Objective:To investigate the effects of posterior internal fixation combined with transpedicular bone grafting in elderly patients with osteoporotic thoracolumbar fractures.Methods:Clinical data of 92 elderly patients with osteoporotic thoracolumbar fractures were retrospectively analyzed.According to the operation method, patients were divided into the control group(n=38)and the observation group(n=54). The control group received the conventional posterior approach and short-segment transpedicular fixation, and the observation group underwent transpedicular fusion in addition to the treatment the control group received.Surgery quality metrics, clinical effects and postoperative recovery were compared between the two groups.Results:The operation time and bleeding volume were higher in the observation group than in the control group( P<0.05). The bone fusion rate was higher and the failure rate of internal fixation was lower in the observation group than in the control group(96.3% vs.78.9%, 3.7% vs.15.8%, χ2=6.929 and 4.103, all P<0.05). The Japanese Orthopaedic Association score(JOA score)increased in both groups after operation( Ftime=47.628, P<0.05). The increase of the JOA score( Finteraction=4.477, P<0.05)and the overall JOA score( Fgroup=5.638, P<0.05)were greater in the observation group than in the control group.The Oswestry Disability Index(ODI)index in both groups decreased with time( Ftime=72.581, P<0.05). The decrease of the ODI index( Finteraction=7.421, P<0.05)and the overall ODI( Fgroup=9.276, P<0.05)were higher in the observation group than in the control group.The visual analogue scale(VAS)score in both groups decreased with time( Ftime=93.157, P<0.05). The decreases of the VAS score( Finteraction=9.473, P<0.05)and the overall VAS( Fgroup=13.272, P<0.05)score were greater in the observation group than in the control group.The Frankel nerve function grade was better in the observation group than in the control group 12 months after operation( z=2.123, P<0.05). Conclusions:Posterior internal fixation combined with transpedicular bone grafting can help improve nerve function, reduce postoperative pain, and has a high bone fusion rate and a low failure rate of internal fixation.
