Background: Total knee arthroplasty (TKA) is a common surgical procedure for patients with knee osteoarthritis. The patellar component plays a crucial role in knee biomechanics and can influence postoperative outcomes. This study aimed to investigate the relationship between radiological indices of patellar height and patient outcomes following TKA. Methods: A retrospective analysis was conducted on patients who underwent TKA for osteoarthritis. Radiographic measurements of patellar height, including the Insall-Salvati (IS) ratio, modified Blackburne-Peel (mBP) ratio, Caton-Deschamps ratio, and plateaupatellar angle (PPA), were obtained. Clinical outcomes were assessed using the Knee Society Score (KSS) and the Forgotten Joint Score-12 (FJS-12). Patient satisfaction and postoperative complications were also evaluated. Statistical analyses, including correlation analysis and multiple regression models, were performed to determine the association between radiological indices and patient outcomes. Results: The study included 330 cases that met the inclusion criteria. The analysis revealed significant correlations between different radiological indices of patellar height and patient outcomes. Lower postoperative PPA was correlated with worse KSS and range of motion scores. A decreased mBP ratio was associated with poorer FJS-12 responses and higher risks of dissatisfaction and patellar clunk or crepitus. Increased IS ratio was linked to a lower likelihood of incidental giving way of the knee. Advanced age was associated with reduced dissatisfaction and incidental giving way probabilities. Conclusions The findings of this study demonstrate that radiological indices of patellar height can predict patient outcomes following TKA. Assessing patellar height using various radiographic measurements provides valuable information for surgical planning and prognostic evaluation. Understanding the impact of patellar height on clinical outcomes can aid in optimizing TKA procedures and improving patient satisfaction. These findings emphasize the importance of considering patellar height as a predictive factor in TKA and highlight its potential role in guiding postoperative management and rehabilitation strategies.

Programmed cell death protein-1(PD-1)/programmed cell death ligand-1(PD-L1)has been considered to be one of the most promising targets for tumor immunotherapy.At present,both monoclonal antibody drugs and small molecule inhibitors targeting PD-1/PD-L1 are facing bottlenecks.Numerous researchers have tried to explore different strategies to block the PD-L1/PD-L1 pathway,hoping to improve the effects of tumor immunotherapy.This review focuses on the degraders,bifunctional molecules and covalent inhibitors that target PD-L1,aiming to provide inspiring insights for the development of anti-PD-1/PD-L1 drugs.

Objective:To investigate the relationship between pancreatic fibrotic marker transforming growth factor-β(TGF-β) and platelet derived growth factor-BB(PDGF-BB) and serum glycated hemoglobin (HbA1c) levels in patients with type 3c diabetes mellitus secondary to chronic pancreatitis(CP-T3cDM).Methods:The clinical data of 39 patients with CP-T3cDM admitted to the Department of Gastroenterology of the First Affiliated Hospital of Naval Medical University between February 2018 and August 2020 were collected, and the patients' age, gender, body mass index, duration of chronic pancreatitis and diabetes mellitus, smoking history, alcohol consumption history, serum HbA1c level at admission, degree of pancreatic atrophy, morphology of the main pancreatic duct, and treatment of diabetes mellitus were recorded. Serum TGF-β and PDGF-BB were detected by ELISA. Patients were divided into high and low level group according to the median TGF-β and PDGF-BB levels, respectively. Clinical characteristics of patients were compared between the TGF-β and PDGF-BB high and low level group. The correlation between TGF-β, PDGF-BB and HbA1c was analyzed by Spearman's correlation analysis.Results:A total of 39 CP-T3cDM patients were included; 35 were male and 4 were female. The age of first onset of chronic pancreatitis was (42±14) years old, and the duration of diabetes mellitus was 24(4, 36) months. The serum HbA1c level was (7.8±1.6)%, and the serum TGF-β and PDGF-BB levels were 20.5(10.5, 43.1) and 647.5(276.9, 1349.2)pg/ml, respectively. The serum HbA1c levels of patients in the high-level group of serum TGF-β and PDGF-BB were significantly higher than those in the corresponding low-level group [8.6%(7.4%, 9.9%) vs 6.7%(6.2%, 7.8%) and 8.6%(7.4%, 9.6%) vs 6.7%(6.1%, 7.8%), respectively] , and the difference was statistically different (both P value <0.01), while none of other indicators showed statistically significant differences between both groups. The correlation analysis showed that the levels of TGF-β and PDGF-BB were significantly positively correlated with HbA1c level ( r=0.45, 0.53, both P value <0.01). Conclusions:Increased pancreatic fibrosis in patients with CP-T3cDM was an important factor contributing to elevated blood glucose level. Patients with higher serum pancreatic fibrotic factors exhibited a significant increase in HbA1c level.

Objective:To investigate the prevalence of pre-diabetes mellitus (PDM) and the impact of occupation-related factors on PDM, among workers from a steel company in Tangshan city, Hebei province.Methods:Clustering sampling method was used to select a steel company and to carry out occupational health-related physical checkup programs for eligible workers who had working in this company for longer than one year. The study began in February and ended up in June, 2017. Workers who were with FPG level as ≤6.9 mmol/L, and free from diabetes, were selected as the subjects for this study. Questionnaires were used and physical examinations and FPG testing conducted.Results:The total number of subjects in this study was 4 173, of which 2 648 appeared as pre-diabetic, with the prevalence rate as 63.4 %. Increase of the PDM prevalence was in parallel with the length of service, among the workers. The risk for the pre-diabetes in those who worked more than 8 hours per day was 1.696 times higher than those who worked less than or equal to 8 h/d (95 %CI:1.517-1.937). Compared with those workers without exposures to heat, noise or carbon monoxides, the proportion of pre-diabetes appeared higher in workers exposed to heat, noise or CO with OR=1.782 (95 %CI: 1.205-2.636), 1.815 (95 %CI: 1.209-2.794) and 1.653 (95 %CI: 1.158-2.361), respectively. Risks for those who were exposed to heat or noise were higher than those who were free from exposure to any occupational hazards ( OR=2.098, 95 %CI: 1.296-3.397). Prevalence rates of pre-diabetes in those who were exposed to heat, noise or CO, were higher than that those who were not. Conclusion:Working hours and exposures to heat, noise or CO appeared as influential factors on PDM.
