Objective To investigate the changes of SCD 14, TNF-?, E-SLT and IL-10 level in the process of infection.Methods Serum E-SLT, IL-10, SCD 14 and TNF-? level was measured in 37 patients of abdominal trauma, and in model rabbits with endotoxemia.Results Serum level of SCD 14,TNF-?,E-SLT and IL-10 on the 1st to 3rd day post-op increased significantly in patients suffering from post-op infection 〔(1.61?0.47)??g/ml, (28.63?8.29)?pg/ml,(153.6?48.9)?ng/ml and (38.21?10.87)?pg/ml, compared with control, all P

Objective To establish musculoskeletal model and finite element model of kidney and blood stasis type knee osteoarthritis (KOA),and to analyze the cartilage stress characteristics of kidney and blood stasis type KOA.Methods Data from knee CT,MRI of kidney and blood stasis type KOA volunteers was used to construct musculoskeletal model and finite element model based on AnyBody and ANSYS software.Surface electromyogram (sEMG) verification and mutual verification were conducted.KOA bone stress and strain parameters were observed at the moving angles of 0°,-40°,-90°,-180° of the KOA musculoskeletal model,in order to explore the cartilage stress characteristics.Results When the positions of kidney and blood stasis type KOA patients varied from standing to squatting,the knee cartilage surface stress revealed a nonlinear increasing trend.Kidney and blood stasis KOA patient's knee cartilage stress near the distal end was significant different from that of normal subjects (P＜0.05),while the KOA patient's knee cartilage stress near the distal end and proximal front side had no significant differences with that of normal subjects (P＞0.05).Conclusions For kidney and blood stasis type of patients with KOA,cartilage surface stress displays a nonlinear increasing trend along with the stress concentration at the motion cartilage surface,which is consistent with the clinical features.

Objective To investigate the feasibility and effectiveness of internal jugular vein (IJV) intervention therapy in patients with cerebral venous sinus thrombosis (CVST)with color Doppler ultrasound (CDU). Methods Twelve patients with CVST diagnosed by CDU and the 13 IJV lesions (localized luminal stenosis in 9 cases,venous long-segment slender in 2 cases,and right IJV localized luminal stenosis,and long-segment slender on the left in 1 case)confirmed by magnetic resonance venography (MRV)and/ or digital subtraction angiography (DSA)were enrolled retrospectively. CDU examinations were used at 1 week before and after IJV intervention therapy,6 months,1 year,and 2 years. The changes of the maximum diameter and the maximum velocity (V max )of the IJV were compared. The success rate and the long-term efficacy of the intervention therapy were analyzed. Results One week after treatment,the CDU examinations showed that the diameter of IJV stenosis in 13 IJV were increased significantly compared with those before procedure (4. 7 ± 2. 1 mm vs. 2. 3 ± 1. 3 mm;t = 5. 325,P < 0. 01). The velocity of blood flow of IJV was improved compared with before procedure (localized stenosis in 10 IJV[50 ± 15 cm/ s vs. 87 ± 24 cm/ s];t = 6. 285,P < 0. 01). Six of the 12 patients were followed up for a mean of 18 ± 7 months, two patients had restenosis after balloon dilatation. Conclusions For CVST patients with IJV lesions,the preliminary observation has indicated that IJV intervention therapy may improve the lesion lumen and hemodynamics. However,the intervention therapy,especially after balloon dilatation,the incidence of restenosis is higher. CDU can be used as an objective evaluation means for the long-term efficacy of IJV stenosis.

Objective To evaluate the reliability of benign nodules diagnosed by ultrasound and analyze the probable factors of infecting the BI-RADS ultrasound categorization of breast lesions. Methods A total of 792 cases with initial category 3 assessments on BI-RADS ultrasound categorization consistent with more than 2 years follow-up or pathologic results were contained. The reliability of probable benign lesions were studied retrospectively,and several factors that could influence the categorization were explored such as age,breast lumps size,multiplicity,palpability,and US radiologist's experience referring to ACR-BI-RADS and the new categorizations recommendation. Results Of 792 breast nodules, 781 (98.6%) were benign and 11 (1.4%) were malignant. If the new categorizations recommendation was applied, 35. 1% (278/792) of all cased would have been upgraded to BI-RADS 4,81. 8% (9/11)of malignant tumors would have been found. The breast masses diagnosed by the junior radiologists were more frequently upgraded to BI-RADS 4 than senior radiologists' findings (P <0. 05), the nodules in women 40 years or older and multiple lesions were more frequently upgraded to category 4 (P <0. 01). The presence of palpability and mass size had on significantly influence the BI-RADS US categorization of breast nodules. Conclusions BI-RADS-Ultrasound categorization is relatively reliable to diagnose breast benign nodules. The multiplicity of breast nodules,patient's age and US radiologist's experience were found to have significant influences on the categorizations of probably benign breast nodules.

Objective:To study the possible immune escape mechanisms of HCoV-OC43 from human dendritic cells(DC).Methods:HCoV-OC43 was isolated from clinical specimen using BSC-1 cells and identified by Real-time PCR,and the cytopathic effect was observed by phase contrast microscope.DCs were induced in vivo using hu-GM-CSF and IL-4 cytokines,and after 7 days of differentiation,DCs were infected by HCoV-OC43.The morphology of HCoV-OC43 infected DC was observed by transmission electron microscope,and the cytokines related to DC functions were detected by Real-time PCR after infection.DC proportion and function related co-stimulatory molecules were analyzed by flow cytometry.Results:In vitro HCoV-OC43 infected human DC model was successfully built.HCoV-OC43 can infect DC and generate immune response of DC in vitro,but no virus nucleonic acid could be detected in culture supernatant.The DC expression of IFN-α,IFN-β,CCL3 and CCL5 were significant decreased when infected with HCoV-OC43,but the expression of costimulatory molecules including HLA-DR,CD1c and CD86 were not affected by HCoV-OC43 infection.Conclusion:Human DC could be infected by HCoV-OC43 and generate immune response,but could not produce progeny virus.HCoV-OC43 may escape from immune response by suppressing the expression of IFN-α and other inflammatory cytokines and chemokines in DC.

Objective To explore the feasibility and efficacy of the selective portal vein embolization (SPVE) before radiofrequency ablation(RFA) for liver tumor large than 3 cm.Methods 63 patients with 63 liver tumor (＞3 cm) located in single liver segment completely or mostly underwent RFA.21 patients (21 lesions) were randomly assigned to receive SPVE before ablation (SPVE + RFA group),other 42 patients were treated with RFA only (RFA group).The complications and treat results of two groups were collected and compared.Results SPVE were achieved in 20 of 21 patients,and no critical complication were happened in both group.During a observation period of median 14.2 months,local tumor progression were observed in 17 of 42 patients (40.5％) in RFA group and in 3 of 20 patients (15.0％) in SPVE+ RFA group,there were significant difference between two groups(P =0.043).Conclusions SPVE can safely and effectively improve the efficacy of RFA for the liver tumors which large than 3 cm and located in single liver segment.

Objective To investigate the effects of contrast dose and region of interest (ROI) depth on quantitative analysis of liver by contrast-enhanced ultrasound (CEUS) during clinical application.Methods After bolus injection of contrast agent,the change of quantitative parameters [including echo mean(EM),rise time(RT),peak intensity(PI),mean transit time(MTT),area under the curve(AUC),time from peak to one half(TPH),wash in slope(WIS),time to peak(TTP)] of time-intensity curves were analyzed based on groups from different doses (1.0 ml and 1.6 ml) and different depth (＜30 mm,30-60 mm,and ≥60 mm).Results MTT and TPH were increased with dose increasing from 1.0 ml to 1.6 ml (P＜0.05).With the dose 1.0 ml,TPH,WIS,PI,AUC and MTT showed significant difference when the depth of the ROI changes (P ＜0.05),with the depth increased,TPH,WIS,PI,and AUC all decreases and MTT increases.For all the other parameters,no significant changes were found (P ＞0.05).Conclusions CEUS and its imaging process can directly influence the accuracy of the parameters from the quantitative analysis.Standardization of contrast agent with predefined dose and depth can potentially facilitate future clinical studies in liver CEUS.
