符合临床要求的烤瓷镍铬合金镀金技术最佳工艺参数的研究

目的:探索符合临床要求的烤瓷镍铬合金最佳镀金工艺参数。方法:根据不同参数组合将试件分为8组,每组8片,其中6片用显微观测划痕法测量镀金层的临界载荷,并用扫描电镜观察镀层截面的质地和厚度,剩余2片用牙刷磨耗试验法测试镀金层的耐磨性能。综合评价后得出符合临床要求的最佳工艺参数。结果:镀金层的临界载荷随镀金时间的增加先增大再减小;镀金电压为0.9V时随着镀金时间的增加,镀金层致密性明显增加而厚度增加不明显,镀金电压为1.0V时随着镀金时间的增加镀金层的致密性和厚度均有明显增加;参数为1.0V360s时镀金层耐磨性能最佳。结论:1.0V360s是符合临床要求的烤瓷镍铬合金镀金技术最佳工艺参数。     

Vitamin D Status Presents Different Relationships with Severity in Metabolic-Associated Fatty Liver Disease Patients with or without Hepatitis B Infection

Whether the associations between serum vitamin D (VitD) and metabolic-associated fatty liver disease (MAFLD) vary with chronic hepatitis B (CHB) infection has not been well established. This study aims to investigate the relationships between serum VitD and metabolism, liver fat content (LFC) and fibrosis among MAFLD patients with and without CHB. Consecutive subjects (healthy controls: 360, CHB: 684, MAFLD: 521, CHB with MAFLD: 206) were prospectively enrolled between January 2015 and December 2021. Anthropometric, laboratory, imaging, and histological evaluations were conducted, with LFC measured via magnetic resonance imaging-based proton density fat fraction (MRI-PDFF). Serum VitD levels were lower in MAFLD patients than in healthy controls and patients with CHB alone or overlapping with MAFLD (24.4 ± 8.1 vs. 29.0 ± 9.5 vs. 27.4 ± 9.6 vs. 26.8 ± 8.4 ng/mL respectively; p < 0.001 in one-way ANOVA test). After adjusting for confounding factors, including season, hypersensitive C-reactive protein, insulin resistance, liver stiffness measurements, sun exposure, exercise and dietary intake, multivariate linear regression analysis revealed that VitD remained significantly negatively correlated with LFC in MAFLD patients (β = −0.38, p < 0.001), but not in CHB with MAFLD patients. Moreover, quantile regression models also demonstrated that lower VitD tertiles were inversely associated with the risk of insulin resistance and moderate–severe steatosis in the MAFLD group (p for trend <0.05) but not in the MAFLD with CHB group. VitD deficiency was associated with the severity of metabolic abnormalities and steatosis independent of lifestyle factors in MAFLD-alone subjects but not in MAFLD with CHB subjects.

Surgical Management for Chronic Destructive Septic Hip Arthritis: Debridement,Antibiotics, and Single‐Stage Replacement is as Effective as Two‐Stage Arthroplasty

ObjectiveTo compare the surgical outcomes of debridement, antibiotics, and single‐stage total hip replacement (DASR) vs two‐stage arthroplasty (two‐stage arthroplasty) for chronic destructive septic hip arthritis (SHA).MethodsCases of chronic destructive SHA treated by DASR or two‐stage arthroplasty in our department from January 2008 to October 2021 were retrospectively reviewed. Patient demographic information, perioperative inflammation markers, intraoperative blood loss, microbial culture, and metagenomic new generation sequencing results were recorded. The perioperative complications, hospital stay, hospitalization cost, infection recurrence rate, and Harris Hip Score (HHS) at the last follow‐up were compared between the two groups.ResultsA total of 28 patients were included in the study, including 11 patients who received DASR and 17 patients who received two‐stage arthroplasty. There was no significant difference in demographic information, preoperative serum inflammatory markers, synovial fluid white blood cell count, or percentage of polymorphonuclear leukocytes between the two groups. The DASR group demonstrated significantly lower intraoperative blood loss [(368.2 ± 253.3) mL vs (638.2 ± 170.0) mL, p = 0.002], hospital stay [(22.6 ± 8.1) days vs (43.5 ± 13.2) days, p < 0.0001], and hospitalization expenses [(81,269 ± 11,496) RMB vs (137,524 ± 25,516) RMB, p < 0.0001] than the two‐stage arthroplasty group. In the DASR group, one patient had dislocation as a complication. There were no cases with recurrence of infection. In the two‐stage arthroplasty group, there was one case complicated with spacer fracture, one case with spacer dislocation, and one case with deep vein thrombosis of the lower limbs. There were no cases with recurrence of infection. There were no significant differences in the readmission rate, complication rate, or HHS at the last follow‐up between the two groups.ConclusionsBoth DASR and two‐stage arthroplasty achieved a satisfactory infection cure rate and functional recovery for chronic destructive SHA, and DASR demonstrated significantly lower intraoperative blood loss, hospital stay, and hospitalization costs than two‐stage arthroplasty. For appropriately indicated patients, if microbial data are available and a standardized debridement protocol is strictly followed, DASR can be a treatment option.
