RESUMO
Objective:To compare the early diagnostic value of the indicators of endothelial injury, renal injury, inflammation and coagulation in patients with sepsis-induced acute kidney injury (AKI).Methods:A retrospective study was performed on 119 patients with sepsis from February 2017 to March 2018. Lab tests were performed on patients at admission, which included:ing soluble thrombomodulin (sTM), tissue plasminogen activators and inhibitors (t-PAI-C), antithrombin III (AT-III), thrombin-antithrombin (TAT) complex, plasmin-alpha 2, plasmin inhibitor complex (PIC), fibrin degradation product (FDP), fibrinogen (FIB), D-Dimer, prothrombin time (PT), prothrombin time international normalized ratio (PT-INR), procalcitoni (PCT), white blood cell (WBC), neutrophil (Neu), and platelet count (PLT). The receiver-operating characteristic curve was used to analyze the predictive value of the above indicators, and logistic regression analysis was used to analyze the risk factors of sepsis-induced AKI. A prospective study was conducted from April 2018 to September 2018 and 46 patients were enrolled. The lab tests results retrieved including sTM, t-PAI-C, FDP, AT-III, TAT, PIC, FIB, D-Dimer, PT, PCT, serum cystatin C (Cys C), urine albumin (microalbumin) and albumin to creatinine ratio (ACR), urinary neutrophil gelatinase-associated lipocalin (uNGAL), urinary N-acetyl-beta-glucosaminidase (uNAG), and urinary retinol-binding protein (uRBP). As same with the previous group, the receiver-operating characteristic curve was used to analyze the diagnostic value of the above indicators, and logistic regression Was used to analyze the risk factors of sepsis-induced AKI.Results:(1) In the retrospective study: sTM, D-Dimer, PCT, PT, and PT-INR were statistically different. sTM, D-Dimer, PCT, PT, and PT-INR had a good diagnostic value for septis-induced AKI, among which, sTM had a highest diagnostic value (AUC: 0.857; 95% CI: 0.790, 0.924), better sensitivity (64.4%) and specificity (91.8%). The high expression of sTM and history of chronic kidney disease were independent risk factors for septis-induced AKI.(2) In the prospective study: PCT, sTM , Cys C, and uNGAL were statistically different. PCT, sTM, Cys C, uNGAL showed good predictive features for septis-induced AKI. sTM had the highest sensitivity (>0.999) while uNGAL had the highest specificity (0.800). The high expression of sTM was an independent risk factor for septis-induced AKI. Conclusions:sTM and uNGAL represent endothelial injury and renal tubular injury respectively. sTM is an independent risk factor of sepsis-induced AKI.
RESUMO
Objective To investigate the MRI findings of perihip heterotopic ossification (HO) in the early, mid and late stages. Meth-ods The MRI of 44 inpatients with HO from February, 2011 to September, 2013 were reviewed, in which 20 cases (28 joints) were in early stage, 18 cases (24 joints) in mid stage and 6 cases (8 joints) in late stage. For the enhanced T1WI, 9 cases (11 joints) were in early stage, 6 cases (7 joints) in mid stage, and 3 cases (4 joints) in late stage. Theχ2 trend test was used to evaluate the MRI signal change with the HO maturity. Results With the maturity of hip HO, the signal intensity of T2WI reduced (χ2=16.773, P<0.001), fat signal on T1WI increased, the enhancement reduced (χ2=16.048, P=0.007). Conclusion The MRI findings of perihip HO are characteristic in MRI in all the stages. MRI is useful for the diagnosis of perihip HO, especially for the early HO.

@#ObjectiveTo investigate the imaging findings of Charcot neuroarthropathy. Methods9 cases with Charcot neuroarthropathy determined clinically or pathologically were reviewed. ResultsThe findings of X-ray and CT including: soft tissue swelling in 9 cases, bone absorption in 5, bone proliferation in 7, periosteal reaction in 7, ectopic calcification or ossification in 9, luxation or semiluxation in 4. For MRI: soft tissue swelling, edema of joint capsule in 2, bone marrow dropsy in 1, sclerotin damage in 1. The joint capsule and periarticular soft tissue unevenly enhanced after Gd-DTPA. Nuclear medicine displayed radioactivity aggregation in 1 case. ConclusionX-rays plain film is the first choice for the diagnosis of Charcot neuroarthropathy, while CT, MRI and nuclear medicine may be helpful.

@#ObjectiveTo explore the superiority of the screw CT in diagnosing the cerebral palsy complicated with dislocation of hip joint compared with the traditional X-ray.Methods35 patients with cerebral palsy were checked with screw CT and X-ray, and then their Perkin's check, Shenton line and Calve line were individually measured.Results24 cases(68.57%) are half dislocation of hip joint. The abnormalities of Perkin's check, Shenton line and Calve line in hip joint showed in screw CT were respectively compared with X-ray. The statistics shows P<0.05 or <0.01.Conclusions The screw CT is superior to the traditional X-ray in diagnosing the cerebral palsy complicated with dislocation of hip joint and can provide the important anatomy information.
RESUMO
Objective To explore the effects of videofluoroscopic swallowing study (VFSS) in the assessment of dysphagia in post-stroke patients. To study the representation and rehabilitative outcome of dysphagia following stroke. Methods Seventy post-stroke patients and 80 normal adults were assigned to study group and control group and underwent VFSS. Abnormal signs on VFSS were compared between 2 groups. Aspiration patients received swallowing therapy for 4 weeks followed by VFSS again. Abnormal signs on VFSS were compared with those of pre-treatment. Results Penetration/aspiration, oral retention and pharyngeal retention occurred respectively at a frequency of 5.0%, 13.4% and 25.3% in control group in mild status, 45.0%,46.5%, 48.9% in study group in moderate to severer status. 10 times of silent aspiration were seen, accounting for 24.4% of all aspiration. The frequency of severe penetration/ aspiration decreased after the treatment (P
