Objective:To explore latent profile categories of pain catastrophizing in total knee arthroplasty patients and analyze differences in kinesiophobia among different categories of patients.Methods:Convenience sampling was used to select 340 patients who underwent total knee arthroplasty at the First Affiliated Hospital of Zhengzhou University from January 2023 to June 2024. The Pain Catastrophizing Scale (PCS) and Tampa Scale for Kinesiophobia (TSK) were used to assess patients' pain catastrophizing and kinesiophobia on the third postoperative day. Latent profile analysis was employed to simulate and categorize PCS, and to compare the kinesiophobia among patients in different categories.Results:A total of 340 questionnaires were distributed, with 327 valid responses collected, resulting in a valid response rate of 96.18%. The postoperative PCS score for 327 patients was (34.76±7.59) , with 33.33% (109/327) achieving a PCS score ≥38. The mean scores for the three dimension (exaggeration, helplessness, and rumination) items were (2.91±0.93) , (2.33±0.84) , and (2.51±0.79) , respectively. The TSK score was (48.39±9.42) , with 50.46% (165/327) scoring above 37. Three latent categories of pain catastrophizing were identified, including "high exaggeration-helplessness-rumination group", accounting for 28.75% (94/327) ; "high exaggeration-moderate helplessness-rumination group", accounting for 39.45% (129/327) ; "moderate exaggeration-helplessness-high rumination group", accounting for 31.80% (104/327) . The TSK scores of the three groups of patients were (51.75±8.49) , (46.83±8.76) , and (49.29±9.04) , respectively, with statistically significant differences ( P<0.05) . Conclusions:Patients undergoing total knee arthroplasty exhibit distinct categorical characteristics in postoperative pain catastrophizing, with varying levels of kinesiophobia observed across different pain catastrophizing characteristics. Healthcare providers should conduct early assessments to identify patients' pain catastrophizing characteristics and deliver targeted interventions to improve pain catastrophizing and kinesiophobia, thereby promoting early postoperative recovery.

Objective To prepare a nano drug(PFOB@Lip-MMC)with liposome as the carrier,liquid perfluorooc-tyl bromide(PFOB)as core and mitomycin C(MMC)loading on the liposome shell and study its inhibitory effect on the proliferation of human pterygium fibroblasts(HPFs).Methods The thin film dispersion-hydration ultrasonic method was used to prepare PFOB@Lip-MMC and detect its physical and chemical properties.Cell Counting Kit-8,Cam-PI cell viability staining and flow cytometry were employed to detect the impact of different concentrations of PFOB@Lip-MMC on the via-bility of HPFs.DiI fluorescence labeled PFOB@Lip-MMC was used to observe the permeability of the nano drug to HPFs under a laser confocal microscope.After establishing HPF inflammatory cell models,they were divided into the control group(with sterile phosphate-buffered saline solution added),PFOB@Lip group(with PFOB@Lip added),MMC group(with MMC added),PFOB@Lip-MMC group(with PFOB@Lip-MMC added)and normal group(with fresh culture medi-um added)according to the experimental requirements.After co-incubation for 24 h,flow cytometer was used to detect the apoptosis rate of inflammatory cells,and the gene expression levels of interleukin(IL)-1β,prostaglandin E2(PGE2),tumor necrosis factor(TNF)-α and vascular endothelial growth factor(VEGF)in cells were analyzed by PCR.Results The average particle size and Zeta potential of PFOB@Lip-MMC were(103.45±2.17)nm and(27.34±1.03)mV,respec-tively,and its entrapped efficiency and drug loading rate were(72.85±3.28)％and(34.27±2.04)％,respectively.The sustained-release MMC of drug-loaded nanospheres reached(78.34±2.92)％in vitro in a 24-hour ocular surface environ-ment.The biological safety of PFOB@Lip-MMC significantly improved compared to MMC.In terms of the DiI fluorescence labeled PFOB@Lip-MMC,after co-incubation with inflammatory HPFs for 2 h,DiI fluorescence labeling was diffusely dis-tributed in the cytoplasm of inflammatory HPFs.The apoptosis rate of inflammatory HPFs in the PFOB@Lip-MMC group[(77.23±4.93)％]was significantly higher than that in the MMC group[(51.62±3.28)％].The PCR examination results showed that the gene transcription levels of IL-1 β,PGE2,TNF-α and VEGF in other groups were significantly reduced com-pared to the control group and PFOB@Lip group,with the most significant decrease in the PFOB@Lip-MMC group(all P＜0.05).Conclusion In this study,a novel nano drug(PFOB@LIP-MMC)that inhibited the proliferation of HPFs was successfully synthesized,and its cytotoxicity was significantly reduced compared to the original drugs.It has good bio-compatibility and anti-inflammatory effects,providing a new treatment approach for reducing the recurrence rate after pte-rygium surgery.

Objective:To explore the adaptive index of pulmonary rehabilitation self-efficacy and its influencing factors in elderly patients with chronic obstructive pulmonary disease (COPD), and to provide reference for formulating and implementing effective intervention strategies.Methods:This was a cross-sectional study. The convenience sampling method was used to select 279 elderly COPD patients hospitalized in the Department of Respiratory and Critical Care Medicine of Xinjiang Uygur Autonomous Region People′s Hospital from March 2023 to June 2023. They were investigated by the general information questionnaire, Chinese version of Pulmonary Rehabilitation Adapted Index of Self-Efficacy, Social Support Scale and Frailty Phenotype. Multiple linear stepwise regression analysis was used to explore the influencing factors of pulmonary rehabilitation self-efficacy in elderly patients with COPD.Results:The age distribution of 279 elderly COPD patients was 117 cases aged 60-69, 102 cases aged 70-79, and 60 cases aged ≥ 80, including 134 males and 145 females. The total score of Chinese version of Pulmonary Rehabilitation Adapted Index of Self-Efficacy in elderly COPD patients was (24.95 ± 5.20) points, and the highest dimension of item mean score was exercise self-efficacy (1.99 ± 0.62) points, while the lowest mean score was strain capacity (1.88 ± 0.44) points. Multiple linear regression analysis showed that educational level, pulmonary function grade, COPD assessment test (CAT) score, social support level and frailty were influencing factors of pulmonary rehabilitation self-efficacy in elderly COPD patients ( t values were - 9.01-3.36, all P<0.05), accounting for 43.4% of the total variation. Conclusions:The self-efficacy adaptation index of pulmonary rehabilitation in the elderly patients with COPD is at the middle-lower level. Health care providers should fully understand the relevant influencing factors, and establish targeted and individualized pulmonary rehabilitation intervention strategies on these basis to maximize the subjective initiative of patients.

Objective To explore the construction and practice of an intelligent prevention and treatment system for venous thromboembolism (VTE) in grassroots hospitals. Methods Based on relevant guidelines and expert consensuses on VTE prevention and treatment, domestic and foreign literature was reviewed. A research and development team composed of clinical experts in VTE prevention and treatment, medical and nursing quality management experts, and information engineers conducted investigations and research in surrounding grassroots hospitals. Through evidence-based research and surveys, the team identified relevant business needs, user needs, and functional requirements of grassroots hospitals, and finally formulated a detailed design plan. The main program of system was written in Java. The interface obtained data from the hospital's data platform through Webservice and view interfaces. To prevent issues of repeated data extraction when multiple applications perform time tasks to assess the same patient during later server usage and expansion, the XXL-JOB distributed task scheduling platform was adopted to handle VTE assessments by medical staff. Results After the clinical application of the intelligent VTE prevention and treatment system, the bleeding risk assessment rate increased from 26.20% at the initial system launch in January 2023 to 83.04% by the end of 2023. In January 2023, the implementation rates of mechanical prevention, pharmacological prevention, and combined prevention for medium-to-high-risk VTE patients were 21.39%, 16.39%, and 5.26%, respectively, which increased to 51.75%, 25.50%, and 25.65% in December 2023. Conclusion The VTE prevention and treatment software system developed by grassroots hospitals can improve development efficiency, enhance the clinical practicality of the system, reduce the workload of medical staff, promote standardization and normalization in VTE prevention and treatment, strengthen closed-loop management of medical quality for VTE as a single disease, and effectively improve the prevention and treatment capabilities and levels of VTE within hospitals.

Objective:To explore the expression levels of adrenomedullin (ADM) in follicular fluid of patients with polycystic ovary syndrome (PCOS) and its correlation with ovarian function and inflammation.Methods:To conduct a cohort study, the data on infertile couples who received an antagonistic regimen of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) to promote ovulation from March to December 2023 at the Reproductive Medicine Center of Shanxi Children's Hospital (Shanxi Maternal and Child Health Hospital) were collected. PCOS patients were selected as the PCOS group, and patients who underwent IVF/ICSI assisted pregnancy solely due to tubal and/or male factors during the same period were selected as control group. The general clinical data of two groups of patients were analyzed, and the expression of ADM, interleukin 1β (IL-1β), IL-18, transforming growth factor β (TGF-β) in the follicular fluid were compared between the two groups of patients. And taking the concentration of ADM in follicular fluid as the main research indicator, correlation and multiple linear regression analysis were conducted with other indicators. Simultaneously the ADM mRNA expression, cell cycle and cell apoptosis of granulosa cells were compared between the two groups. Results:This study included 20 cases in the PCOS group and 20 cases in control group. Compared with control group, the expression of ADM in follicular fluid and granulosa cells of patients with PCOS were significantly lower (both P<0.001), while its testosterone, the ratio of luteinizing hormone and follicle-stimulating hormone, antral follicle count (AFC), number of retrieved eggs, ovarian sensitivity index, as well as IL-1β, IL-18 and TGF-β in follicular fluid were higher and negatively correlated with ADM ( r=-0.37, P=0.019; r=-0.32, P=0.047; r=-0.50, P<0.001; r=-0.38, P=0.017; r=-0.38, P=0.016; r=-0.44, P=0.005; r=-0.37, P=0.018; r=-0.54, P<0.001). Multiple linear regression showed that AFC, gonadotropin initiation dose, IL-1β and TGF-β were the independent related factors that affect local ADM levels ( r=-0.37, P=0.008; r=-0.27, P=0.035; r=-0.28, P=0.028; r=-0.45, P<0.001). There was no statistically significant difference in the cell cycle of granulocytes between the two groups ( P>0.05), but the apoptosis rate (AR) of granulocytes was higher in the PCOS group than in control group (median AR in the PCOS group was 46.07%, median AR in control group was 28.57%, n=10, P=0.036). Conclusion:The decreased expression of ADM in follicles of PCOS patients is related to ovarian endocrine disorders, multiple vesicles, high ovarian responsiveness and local inflammatory status.

【Objective】 To study the effect of perioperative allogeneic blood transfusion on patients with oral squamous cell carcinoma (OSCC) after first-stage free flap transplantation. 【Methods】 A total of 306 OSCC patients who accepted primary repair and reconstruction using free flap admitted to our affiliation from January 2010 to January 2019 were selected as the research objects and retrospectively analyzed. According to their clinical data, they were divided into three groups: no transfusion group (n=98), 1-2 U transfusion group (n=131) and 3 + U transfusion group (n=77), respectively. The incidence of complications including flap infection, blood circulation disorder and hematoma in the three groups were compared. The five-year survival rate of the three groups was calculated by Kaplan-Meier analysis, and the relative risk of death was analyzed by Cox regression. 【Results】 There was no statistically significant difference among the three groups of patients (P>0.05) regarding such baseline data as embracing gender, age, primary location, degree of differentiation, adjuvant radiotherapy and chemotherapy. The complication rate of patients with 3 + U transfusion (25.97%) was significantly higher than that of no transfusion (6.12%) and 1-2 U transfusion (10.86%) (P<0.05); and the five-year survival rate of patients with 3 + U transfusion (51.95%) was significantly lower than that of no transfusion (69.38%) and 1-2 U transfusion (62.60%) (P<0.05). The results of univariate analysis showed that age, adjuvant radiotherapy, degree of tissue differentiation, collateral infiltration, vascular invasion and blood transfusion were all factors influencing the quality of prognosis after repair and reconstruction of first-stage free flap transplantation treating OSCC (P<0.05). The results of multivariate analysis showed that adjuvant chemoradiotherapy was an independent protective factor for the prognosis and survival quality of postoperative OSCC patients (P<0.01); the degree of differentiation, vascular invasion and blood transfusion were independent risk factors for the prognosis and survival quality of postoperative OSCC patients (P<0.05). 【Conclusion】 Perioperative allogeneic transfusion in OSCC patients can increase the risk of postoperative complications and directly affect their prognostic quality. It can be regarded as an important risk factor for OSCC patients.
