The reconstruction of the temporomandibular joint presents a multifaceted clinical challenge in the realm of head and neck surgery, underscored by its relatively infrequent occurrence and the lack of comprehensive clinical guidelines. This review aims to elucidate the available approaches for TMJ reconstruction, with a particular emphasis on recent groundbreaking advancements. The current spectrum of TMJ reconstruction integrates diverse surgical techniques, such as costochondral grafting, coronoid process grafting, revascularized fibula transfer, transport distraction osteogenesis, and alloplastic TMJ replacement. Despite the available options, a singular, universally accepted 'gold standard' for reconstructive techniques or materials remains elusive in this field. Our review comprehensively summarizes the current available methods of TMJ reconstruction, focusing on both autologous and alloplastic prostheses. It delves into the differences of each surgical technique and outlines the implications of recent technological advances, such as 3D printing, which hold the promise of enhancing surgical precision and patient outcomes. This evolutionary progress aims not only to improve the immediate results of reconstruction but also to ensure the long-term health and functionality of the TMJ, thereby improving the quality of life for patients with end-stage TMJ disorders.

Objective:This study aimed to explore the feasibility and clinical value of monitoring the progression of early kidney injury in type 2 diabetic patients by assessment of the urinary C-terminal agrin fragment (uCAF) with enzymatic chemiluminescence immunoassay.Methods:A total of 251 patients with type 2 diabetes, who attended the Second Affiliated Hospital of Wenzhou Medical University from October 2018 to March 2020, were included in this retrospective analysis. One hundred and fifty-six participants undergoing health check-up at the Second Affiliated Hospital of Zhejiang University School of Medicine in February 2021 served as controls. Basic clinical information, glycosylated hemoglobin type A 1c and serum creatinine values were recorded, and urine specimens were collected for urinary creatinine, urinary α 1 microglobulin(uα 1M), urinary immunoglobulin G (uIgG), urinary albumin, urinary N-Acetyl-B-D-glycosaminidase (uNAG) and uCAF measurements. Based on the estimated glomerular filtration rate (eGFR), 251 patients were classified into G1~G5 stage groups with 116, 22, 28, 55 and 30 patients in each group. One hundred and sixty-six patients with early diabetic kidney disease (stage G1-G3) were divided into subgroups A1 (79), A2 (48) and A3 (39) according to the urinary albumin/creatinine ratio (UACR), the uα1M levels were divided into uα1M subgroup 1 (83 cases), uα1M subgroup 2 (42 cases), and uα1M subgroup 3 (41 cases), and uIgG subgroup 1 (83 cases), uIgG subgroup 2 (42 cases), and uIgG subgroup 3 (41 cases) according to uIgG levels. The Spearman method was used to analyze the correlation between uCAF levels and eGFR, UACR, uα1M and uIgG levels. Results:(1) The linear range of the uCAF detected by enzymatic chemiluminescence immunoassay was 3.97-2 000.00 ng/ml, with a detection limit of 2.28 ng/ml, intra-batch coefficients of variation of 1.15% and 1.57%, inter-batch coefficients of variation of 1.63% and 5.78%, and a biological reference interval of <95.35 μg/g Cr. (2) The uCAF level and positive rate (UACR≥30 mg/g) increased with the decrease of eGFR from G1-G3, uCAF level was negatively correlated with eGFR value ( r=-0.543, P<0.000 1), and the positive rate increased from 24.14% (28/116) to 85.71% (24/28) from G1-G3. The uCAF level and positivity rate decreased with the decrease of eGFR from G4 to G5. uCAF level was positively correlated with eGFR value ( r=0.495, P<0.001), and the positivity rate decreased from 30.91% (17/55) to 23.33% (7/30) from G4 to G5. (3) In patients with early diabetic kidney disease, uCAF levels and positivity rates increased gradually with the increase of UACR. uCAF levels were positively correlated with UACR values ( r=0.602, P<0.001), and the uCAF positivity rate reached 21.52% (17/79) in the A1 subgroup. (4) uCAF level was positively correlated with uα1M and uIgG levels in patients with early diabetic kidney disease ( r=0.757, 0.596, both P<0.001). Conclusion:Analytical performance of enzyme chemiluminescence immunoassay for the detection of CAF is satisfactory and could be used a biomarker for monitoring damage and progression of early diabetic kidney disease in patients with type 2 diabetes.

Objective To investigate the effect of dysphagia screening and prospective interventional nursing in reducing the aspiration pneumonia in stroke patients.Methods 186 patients with acute stroke were randomly divided into control group and interventional group,93 cases in each group.The Watian drinking water test was used to screen dysphagia,and the routine nursing was used in the control group.The combined screening of Watian drinking water test and oxygen desaturation monitoring was used to screen dysphagia,and prospective intervention nursing in addition to the routine nursing was used in the interventional group.The detection rate of dysphagia and the incidence of aspiration pneumonia in 4 weeks were compared between the two groups.Results The detection rate of dysphagia in the intervention group was higher than that in the control group (41.9% vs 19.4%,χ2 =11.16,P <0.01),and the incidence of aspiration pneumonia was lower than that in the control group (12.9% vs 4.3%,χ2 =4.38,P <0.05).Conclusion The detection rate of dysphagia can be improved by using the combined screening of Watian drinking water test and oxygen desaturation monitoring.The incidence of aspiration pneumonia can be reduced by using combined screening with additional prospective interventional nursing.
