Purpose To evaluate the value of imaging on the diagnosis and treatment of human-infected H10N8 virus. Materials and Methods The chest X-ray and CT features of one case of human infected H10N8 virus were retrospectively studied. Results A 73-year-old female patient was admitted to the third affiliated hospital of Nanchang University on November 30, 2013 due to cough, sputum for 3 days and fever for 1 day. The patient was diagnosed with severe pulmonary infection and underwent chest CT on December 1, which showed large opacities with air bronchograms were in the lower lobe of her right lung and ground-glass exudative lesions in the lower lobe of the left lung;the next 24 h, 48 h and 72 h review tracking chest X-ray showed the chest lesions developed rapidly which involved more lobes with more areas, integration of lesions and plenty of pleural effusion in a very short time. This was a typical white lung sign of acute respiratory distress syndrome. The patient died later on December 6, which was reported as the case of human-infected avian influenza (H10N8 virus) by Chinese Center for Disease Control and Prevention. Conclusion The chest imaging features found in human infected H10N8 virus present as progressive opacities and exudative lesions.

Objective To compare the results of single and repeated percutaneous sclerotherapy in patients with simple renal cysts .Methods 96 patients with simple renal cysts underwent needle aspiration and sclerotherapy under CT guidance. 45 patients (group A) underwent one session of sclerotherapy with 99.7% ethanol immediately after aspiration and 51 patients (group B) underwent repeated sclerotherapy at least twice. The patients were followed up using ultrasonography or CT at 3～6 months intervals. The complete or almost disappearance of the renal cyst was considered a successful treatment.Results The efficacy of treatment was significantly different in two group . The overall effective rate were 91.1% and 98.8% in group A and group B , respectively. The rate of complete regression was significantly better in group B (80.4%) than in group A (62.2%,?

Objective To explore the MRI T 1WI features of the hyperacute intracerebral hematoma by super-low-field MR.Methods 160 patients with hyperacute intracerebral hematoma were examined by using MR unit of 0.04T magnetic(WDLMW-400) and PS3D T 1WI(TR=125 ms,TE=25 ms).Results Hematomas located in basal ganglia(140 cases),cerebral lobe(13 cases),cerebellum(5 cases) and brain stem ( 2 cases) respectively.All of the hyperacute hematomas showed short T 1 signal intensity in PS3D T 1WI;the mass effects and perihematoma edema also can be found in all of the 160 cases.Conclusion This study shows that the super-low-field MRI is superior to medium and high field MRI in diagnosis of hyperacute intracerebral hematoma.

Objective To conduct a systematic review to evaluate efficacy and safety of bladder neck preservation techniques during radical prostatectomy.Methods We searched PubMed,Embase,Medline,Central (the Cochrane Library,Issue 1,2013),CNKI,CBM from the inception to July 2015 for randomized or observational studies assessing the influence of preservation of bladder neck on the continence recovery and cancer control outcomes after radical prostatectomy.Two researchers evaluated the quality of included studies.A meta-analysis was conducted using Review Manager 5.0 software.Results Twelve observational and two randomized studies were analyzed.BNP group had a faster recovery of early continence than non-BNP group at 1 month[OR =2.88,95％ CI 1.80-4.60,P ＜ 0.05],3-4 months [OR =2.32,95％ CI 1.42-3.80,P ＜ 0.05].However there was no statistically significant difference in terms of continence rate at 6 months [OR =1.49,95％ CI 0.97-2.29,P =0.07] and 12 months [OR =0.99,95％ CI 0.70-1.39,P =0.93] among two groups.There was no significant difference in terms of PSM rate [OR =0.92,95 ％ CI 0.71-1.19,P =0.52] between BNP and non-BNP groups.Conclusions We found that preservation of the bladder neck result in earlier return of urinary continence without adversely affecting cancer control.

BACKGROUND: The most frequently encountered problem that an orthopedic doctor encounters in treating humerus fracture is how to choose the exact direction and amount of load applied on humerus.OBJECTIVE: To explore the clinical significance of establishing a three-dimensional model and finite element analysis in treating humerus fracture and to provide theoretical basis for applying appropriate axial stress.DESIGN: The three dimensional model of humerus was reconstructed, on which compression from different directions was applied.SETTING: Orthopedic department of an affiliated hospital and life science laboratory of a university.MATERIALS: A humerus specimen received CT scanning and the trial was conducted in Shanghai Changhai Hospital and Life Science Laboratory of Tongji University from April 2002 to April 2004.METHODS: The three dimensional model of humerus was established and relevant calculation was completed with ANSYS 5.6 software. The humerus model was divided into 2 729 nodes and 49 041 units based on a three-dimensional ten-node tetrahedron as one unit. The distribution and intensity of axial compression on the fracture gap section were calculated and analyzed in the following conditions, i. e. when the humerus was fixed in X, Y and Z directions and the fracture gap section was 30°, 45°, 90° to Z axis.MAIN OUTCOME MEASURES: The axial pressure on the fracture gap section in different conditions to provide evidence for clinical treatment.RESULTS: The stress applied on the fracture gap was relatively concentrated and was 2 -3 times stronger than that in other areas, and it was generally symmetrically distributed within 10 mm around the fracture gap.CONCLUSION: The required load on humerus fracture should be calculated before a suitable implant is applied to accommodate the movement of humerus without compromising healing of the fracture.

Objective To explore the effects of volatile oil and 2-undecanone from Houttuynia Cordata Thunb. (H. cordata) on LPS-TLR4 / MD-2-TNF-α signaling pathway. Methods TLR4 / MD-2 blocking agent was used to mask the TLR4 /MD-2 site,then protein expression levels of TLR4 in cells treated with volatile oil and 2-undecanone were analyzed by western blot. ELISA was used to detect the secretion of the inflammatory cytokines such as TNF-α,IL-1β and IL-10. Comparison analysis was then performed from the results of cell experiments in vitro and anti-inflammatory effects through xylene-induced ear edema test in vivo. Results In concentrations between 1 to 10 μg · mL-1 ,Houttuynia volatile oil showed better effect than 2-undecanone on inhibition of TLR4 protein in LPS-induced RAW264. 7 cells, and had some differences in the effects on inflammatory factors. Compared with the LPS+TLR4 / MD-2 group,the LPS+TLR4 / MD-2 + volatile oil group had no significant difference in the expression of TLR4 protein (P>0. 05),but the LPS+TLR4 / MD-2 +2-undecanone group reduced the expression of TLR4 protein obviously. It appeared that volatile oil exerts its anti-inflammatory effect through LPS-TLR4 / MD-2-TNF-αpathway,but 2-undecanone may exert its anti-inflammatory effect by other means. Houttuynia volatile oil showed better anti-inflammatory activity than 2-undecanone in vivo at the same dose. Conclusion There are some differences in anti-inflammatory effects and related mechanisms between volatile oil and 2-undecanone, probably owing to the synergistic effects of multi-ingredients in the volatile oil.

Objective To explore the prognostic value of pre-chemotherapy serum cystatin C (Cys C) in patients with castration-resistant prostate cancer (CRPC).Methods The medical records of 48 patients with CRPC were reviewed.These patients were diagnosed and underwent docetaxel-based chemotherapy in Xinjiang Military Command General Hospital between January 2009 and January 2015.Statistical analysis was performed to identify the clinical and prognosis value of Cys C.Results Of 48 patients with CRPC,the expression of serum Cys C before chemotherapy was related with Gleason score (x2 =4.218,P =0.040) and distant metastasis(x2 =4.090,P =0.043).23 patients was in high group (Cys C ＞ 1.61 mg/L),25 in low (Cys C ≤ 1.61 mg/L).The median survival time of high group and low group were 15.6 and 25.3 months,respectively (x2 =13.876,P ＜ 0.001).Univariate analysis showed that TNM stage (x2 =6.934,P =0.018),Gleason score (x2 =7.933,P =0.005),baseline prostate specific antigen (PSA) (x2 =9.038,P =0.003),number of chemotherapy cycles (x2 =5.024,P =0.028),distant metastases (x2 =6.963,P =0.013) and serum Cys C before chemotherapy (x2 =6.976,P =0.012) were associated with overall survival of patients with CRPC.COX multivariate analysis showed that baseline PSA at diagnosis (x2 =4.257,P =0.039),number of chemotherapy cycles (x2 =6.245,P =0.017),distant metastases (x2 =5.122,P =0.028) and serum Cys C before chemotherapy (x2 =8.172,P =0.004) were independent risk factors of overall survival of patients with CRPC,especially serum Cys C before chemotherapy (HR =2.394).Conclusion The patients with high Cys C level have poor prognosis,and the pre-chemotherapy Cys C is an independent risk factor for prognosis of CRPC patients treated with docetaxel-based chemotherapy which can be used as an effective indicator to assess the prognosis of CRPC.
