Objective To investigate the risk factors of worsening renal function (WRF) in patients with chronic heart failure ( CHF) and WRF influence on prognosis. Methods A case-control study were undertaken to analyze independent risk factor statistically related to incidence of WRF, and to assess the influence of WRF on prognosis. Results The independent predictors of WRF were creatinine level at admission (OR 2.248,95% CI 1.088-4.647, P = 0.029) and NYHA class on admission ( OR 2.485, 95% CI 1.3854. 459, P = 0.002). The mortality of patient with WRF was obviously higher than that of control group during hospitalization( OR 3. 824,95% CI 2. 452-5. 637 ,P <0.015). Conclusions WRF is a common complication among patients hospitalized for CHF, and is obviously associated with mortality during hospitalization. Higher creatinine level and weak heart function are independent risk factors for incidence of WRF of patients with CHF.

Objective To synthesize 4 kinds of 111 In?TPP cations and evaluate their properties as tumor cationic radiotracers in vivo and in vitro. Methods DO3A?xy?TPP, DO3A?xy?mTPP, DO3A?xy?dmTPP and DO3A?xy?tmTPP were radiolabeled with 111 In;their lipid?water partition coefficients and in vivo and in vitro stability were evaluated. The binding affinities of 4 kinds of 111 In?radiotracers were determined in cell uptake and cell efflux assay using U87MG tumor cells. Biodistribution studies and γ imaging studies were performed using the athymic nude mice bearing U87MG human glioma xenografts to explore the biologi?cal properties of 4 kinds of 111 In?radiotracers. One?way analysis of variance was used. Results The labeling yields of 4 kinds of 111 In?radiotracers were all above 85%, and the radiochemical purity were all greater than 99% after purification. Binding assay in U87MG cells showed that 4 kinds of radiotracers had great binding affinity and cell retention ability, and 111In?DO3A?xy?mTPP had the best binding ratio (1?49%;F=177.8, P<0.05) . Gamma imaging and biodistribution results showed that the U87MG tumors could be clearly visualized by 111In?DO3A?xy?mTPP, 111In?DO3A?xy?dmTPP and 111In?DO3A?xy?tmTPP, and the liver uptake of the 3 tracers was lower than that of 111In?DO3A?xy?TPP. In particular, 111In?DO3A?xy?mTPP had the best tumor/liver ratio (0.13±0.05, 2 h postinjection;F=9.4, P<0?05). Conclusions The tumor?targeted ability of 111In?DO3A?xy?mTPP is better than those of 111In?DO3A?xy?dmTPP, 111In?DO3A?xy?tmTPP and 111In?DO3A?xy?TPP, suggesting that it has the potential to be a promising tumor cationic radiotracer.

BACKGROUND:Finite element analysis is a commonly used mathematical modeling method to analyze the biomechanics of the lumbar spine.By constructing finite element models of the complex tissues such as muscles,blood vessels,and nerves in the lumbar region,mechanical analysis is performed to elucidate the pathogenesis of lumbar spine disorders and the mechanical mechanisms of treatment approaches. OBJECTIVE:To review the progress of finite element analysis in understanding the pathogenesis and treatment modalities of lumbar spine disorders,and to propose a new clinical workflow for the implementation of finite element analysis,aiming to provide a reference for future studies and promote the widespread utilization of finite element analysis in clinical diagnosis and treatment. METHODS:The PubMed database was searched using English keywords"finite element analysis,lumbar vertebra",while the WanFang and China National Knowledge Infrastructure(CNKI)databases were searched using Chinese keywords"finite element analysis,lumbar vertebra".A total of 73 articles were included for review. RESULTS AND CONCLUSION:(1)Lumbar spine degeneration in non-slipped patients typically originates from the posterior annulus fibrosus,while in patients with lumbar spine spondylolisthesis,degeneration starts from the lumbar facet joints due to abnormal mechanical mechanisms.(2)Restoring vertebral body height can prevent adjacent-level degeneration,and finite element analysis-measured vertebral compression strength can serve as an effective predictor of fracture risk,replacing bone density measurements.(3)In lumbar spine fusion surgery,selecting fusion devices of appropriate height and placing them transversely can prevent device subsidence.Increased intervertebral strain,circumferential stress,and intervertebral pressure in adjacent segments after fusion surgery may contribute to the occurrence of degenerative changes in neighboring segments.(4)Finite element analysis results suggest that preoperative planning for transforaminal endoscopic surgery should include considerations for osteotomy size to avoid excessive destruction of the articular process,and intraoperatively,preferential selection of a technique that traverses the superior articular process for foraminal dilatation.(5)In percutaneous kyphoplasty,bilateral pedicle screw augmentation should be performed,distributing bone cement on both sides of the pedicle.More advanced non-aluminum glass polyalkenoate cement materials should be selected.(6)Traction therapy should be personalized based on individual patient characteristics,including customized traction angles and forces,to achieve optimal therapeutic effects.(7)Manual therapy can induce relative displacement between the herniated intervertebral disc and the nerve root,thereby reducing compression.(8)The workflow involving CT/MR-AI Plus FEA-AI Plus Surgical robots can enable more precise diagnosis and treatment.
