0 05) The plasma Hcy level was significantly higher in DVT group than in control group [(12 2?8 7) ?mol/L vs (10 4?4 8) ?mol/L, P

0.05). Conclusion:There is bigger difference process of tumor apoptosis between different cell types in the same topography site. Survivin may play adjuvant roles and Bcl-2 may play main roles in the inhibition of cell apoptosis in SCLC while the case is just reversed in NSCLC,it suggests that there were different apoptosis inducing factor and different apoptosis pathway due to different cell type in NSCLC and SCLC.

Objective To analyze the significance of global end-diastolic volume index (GEDVI) in acute kidney injury (AKI) after septic shock.Methods A retrospective analysis of 61 patients was performed.The patients were diagnosed of septic shock in emergency ward of Shenyang Military Hospital from 2012 March to 2013 May and were monitored by pulse indicator continuous cardiac output (PiCCO).The patients were divided into two groups:low GEDVI group (GEDVI ＜ 700 ml/m2,29 cases) and high GEDVI group (GEDVI≥700 ml/m2,32 cases) by evaluating GEDVI of 24 hour after PiCCO.Several physiologic and biochemical indexes were recorded,including the hemodynamic parameters at the beginning and the 24 h of PiCCO monitoring,Scr,BUN,lactic acid,incidence and mortality of AKI,baseline glomerular filtration rate,baseline Scr,APACHE Ⅱ scores,mortality during the period of emergency ward or within 28 d after the diagnosis.Results A total of 26 cases in high GEDVI group (81.3％) were attacked with AKI,while 16 cases in low GEDVI group (55.2％) were attacked with AKI,the incidence of AKI in high GEDVI group was significantly higher than that in the low GEDVI group.A COX regression analysis of mortality was performed between the patients staying at emergency ward and during 28 d after diagnosis.The results indicated that AKI and GEDVI had no relation with patients' death.Therefore,AKI and GEDVI could not be considered as the risk factors for the prognosis.Conclusions High GEDVI can significantly increase the incidence of AKI after septic shock,therefore high GEDVI should be avoided as much as possible in the course of clinical treatment.

Objective To assess the clinical efficacy of Shenmai injection for the treatment of anaphylactic shock patients and to observe the changes of microcirculation, blood pressure, and volume of urine. Methods Sixty cases of anaphylactic shock were treated with Shenmai injection plus Western medicine (treatment group) and 36 cases of anaphylactic shock treated with Western medicine only(control group). Hemorheological changes, consciousness, temperature, pulse and NSPO 2 were compared. Results The blood pressure recoverable rate of anaphylactic shock in the treatment group was significantly higher than that in the control group. The blood pressure recoverable rates at 4 h after the therapy were 68.3% and 22.2% in the treatment group and the control group, respectively. The average urine volume of treatment group at 2, 3, 4, 5 and 6 h after the therapy was significantly higher than that of the control group ( P

Objective To investigate the inactivating effect of heat and ultraviolet(UV) light on HCV JFH-1 strain using the cell culture system. Methods The HCV JFH-1 virus stock, with an initial titer of 2.5 × 104 FFU/ml, was exposed in 56℃ water bath or to UV light for varying durations of time for explo-ring their inactivating effects on the virus. The kinetics of virus titer reduction was determined by an indirect immuno-fluorescence assay (IFA). If the cells infected with the exposed virus stock were IFA negative after three blind passages, the virus stock was considered to be inactivated completely. Results After incubation of the HCV JFH-1 virus stock (2.5 × 104 FFU/ml)in 56℃ water bath for 10 min, 20 min and 30 min, the virus titers were reduced to 1.6 × 103 FFU/ml, 3.1 × 102 FFU/ml and 3.3 × 10 FFU/ml, respectively. The exposure of the virus stock to UV light (wavelength 253.7 nm, intensity ≥60 μW/cm2, 30 cm below the UV lamp) for 15 s, 30 s and 45 s resulted in virus fiter reduction to 1.0 × 103 FFU/ml, 1.1 × 102 FFU/ml and 2.7 × 10 FFU/ml, respectively. After 40 min incubation of the virus stock at 56℃, or 1 min exposure to UV light (wavelength 253.7 nm, intensity ≥60 μW/cm2) the virus infectious titer was reduced below the detection limit of IFA, and the IFA was still negative even after three blind passages, indicating that the virus was inactivated completely. Conclusion HCV is sensitive to heat and UV light treatment. For HCV JFH-1 virus stock containing 2.5 × 104 FFU/ml virus, heat treatment at 56℃ for 40 min, or UV light expo-sure at an intensity of ≥60 μW/cm2 for 1 min, resulting in complete virus inactivation.

Objective: To study the solubilization of sulfonated butyl ether-β-cyclodextrin (SBE-β-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD) for voriconazole (VCZ) to lay basis for the preparation of inclusion compounds of VCZ.Methods: The phase-solubility method was used, and the solubilization of SBE-β-CD and HP-β-CD at different concentrations for VCZ was studied at various temperatures and the inclusion constant (K) and such inclusion parameters as ΔG, ΔH and ΔS were calculated.Results: Both SBE-β-CD and HP-β-CD could improve the solubility of VCZ in water, while the solubilization of SBE-β-CD was more significant than that of HP-β-CD at the same concentration under the same temperature.The equilibrium phase-solubility diagram of SBE-β-CD vs VCZ was AN type, and that of HP-β-CD vs VCZ was AL type.With the increase of temperature, K of both β-CD decreased.ΔG, ΔH and ΔS were all negative for the inclusion process.Conclusion: Compared with that of HP-β-CD, the solubilization of SBE-β-CD for VCZ is better.The inclusion is spontaneously formed with exothermic process, and the main acting force is Van der Waals'' force.

BackgroundIt has been proved that,after being forced,the biological soft tissue has stable biomechanical characteristics.However,there is rare study on corneal biomechanics.Rabbit is a main animal for experimental study in ophthalmology.But the biomechanical study of cornea in normal rabbit has not been reported.ObjectiveThis study was to investigate the biomechanical properties of normal rabbit central cornea and acquire the parameter. Methods Ten rabbits were sacrificed and the whole corneas were obtained and 20 central cornea specimens with 7 mm×5 mm of rabbit were prepared and tested on BOSE electroforce 3220-AT biomechanics machine under the room temperature and suitable humidity environment.Uniaxial tension,stress between strain,relaxation and creep were performed and the curves were drawn.The data was collected by wintest system to evaluate the biomechanical parameters of rabbit corneal tissue. ResultsThe maximum distortion intension of rabbit cornea was (7.7432±0.6099)MPa.After three cyclic loading,the stress gradually attenuated and the stress and strain flattened as the time change with the relaxation rate 30.33％.The deformation of the specimens enhanced with time decrease with the creep rate 24.33％. ConclusionsThe biomechanical characteristics of normal rabbit cornea are revealed in this study,which offer the basis for the experimental research of rabbit model aimed at corneal disease.

Objective To obtain more information concerning polymorphism of the thyrotropin (TSHR) in Graves diseases(GD). Methods (1)A family of GD was studied (including 3 patients and 9 healthy family members)to examine SNPs of TSHR through direct sequencing of all 10 exons and part of introns. (2)In the current case-control study, 30 patients with familiar GD, 48 sporadic patients and 96 healthy control individuals were used to assess whether SNP of TSHR was associated with GD. Genomic DNA was extracted from peripheral leukocytes isolated from ACD-anticoagulated blood. Ten exons were amplified by PCR, using primers designed by ourselves. After purifying, the products were sequenced. Results Eight polymorphisms were found. There was a novel polymorphism in exon 8. There were no significant differences between patients and controls. Conclusions These findings suggested that the novel and other polymorphisms of the TSHR gene may not be responsible for GD. There are racial differences in the distribution of polymorphisms of TSHR gene.
