Objective To investigate the effect of mechanical ventilation in acute organophosphorous pesticide poisoning(AOPP) with respiratry failure. Methods Forty from forty-two AOPP patients with respiratry failure were treated with mechanical ventilation(MV) ,gastrolavage and other methods. Five minutes before mechanical ventilation and two hours after mechanical ventilation, patients' heart rate (HR), systolic blood pressure (SBP), arterial partial blood pH, oxygenation index, the pressure of carbon dioxide (PaCO2) were compared. Results Patients' HR was increased ( P＜0. 05 ), SBP was increased ( P＜0. 01 ), arterial partial blood pH was increased( P＜0. 01 ), oxygenation index was increased(P＜0. 01 ) ,PaCO2 was decreased(P＜0.01 ). Thirty nine cases were cured,three cases dided. Conclusion Mechanical ventilation can effectively treat the AOPP patients with respiratry failure.

Objective:To explore the changes of NK and NKT cells and the expression levels of their activated, inhibitory receptors in the peripheral blood of patients with newly diagnosed rheumatoid arthritis ( RA), and to reveal the potiential role of NK and NKT cells played in the pathogenesis of RA.Methods:32 patients with new onset RA and 15 healthy controls were recruited.Activated and inhibitory NK and NKT cells in peripheral blood were quantified by flow cytometry.The frequency of spontaneous and stimulated IFN-γ+NK and NKT cells and CD107aγ+NK cells were examined.Finally,the potential relationship between the frequency of NK and NKT cells subsets and clinical indexes were analyzed.Results:The frequencies of NK cells in peripheral blood in RA patients were sig-nificantly lower than those in the controls ( P=0.026 ).The frequencies of NKG2D+, NKP46+activated NK cells and NKG2C+, NKG2D+,NKP46+activated NKT cells in RA patients were significantly higher than those in the controls (P=0.011,P=0.010,and P<0.001,P=0.032,P=0.001,respectively),whereas the frequencies of KIR2DL3+,KIR3DL1+and NKG2A+inhibitory NK cells and KIR2DL3+,NKG2A+inhibitory NKT cells in RA patients were significantly lower (P=0.002,P=0.002,P=0.014,and P=0.027,P=0.002,respectively).Moreover, the frequencies of stimulated IFN-γ+NK cells and IFN-γ+NKT cells, spontaneous and stimulated CD107 aγ+NK cells in RA patients were significantly higher than that in the controls ( P=0.037, P=0.004 and P=0.001, P=0.001, respectively).Furthermore,the frequencies of NK cells,NKG2Aγ+and KIR2DL3γ+inhibitory NK cells were correlated significantly with the values of DAS28 in RA patients (r=0.357,P=0.045;r=0.399,P=0.024;r=0.468,P=0.021,respectively).Conclusion:Lower frequencies of NK cells, higher frequencies of activated NK cells and activated NKT cells, lower frequencies of inhibitory NK cells and inhibitory NKT cells, and higher NK cell activity may induce the autoimmune reaction involved in the pathogenesis of RA.

Objective To observe the effects of infrasound on rat myocardial cells and to study its underlying mechanism. Methods One hundred Sprague-Dawley rats were divided into a normal control group and a infrasound exposure group, composed of various subgroups subject to exposure to infrasound for 2 hours daily for 1 d,7 d,14 d,21 d,and 28 d, respectively. The ultra-microstructure and apoptosis of the rat myocardial cells were observed, and SOD and MDA were measured. Results After exposure to infrasound, significant ultra-microstructural impairment and increased apoptosis of the myocardial cells were observed in the infrasound exposure group as compared to those of the normal 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 set up an optimized protocol for aneuploidy detection from single cells through Array- Comparative Genetic Hybridization (CGH).[Method] Two cell lines,trisomy 18 (Tri-18;GM02732,47,XY,+18) and chromosome 4 segment deletion [sDel-4;GM00343,46,XY,4(del) (qter ＞ p14)],were used in the study.In combination of 10 k 2.0 SNP mapping array platform and multiple displacement amplification (MDA),the diagnostic accurate rates of MDA product from single cells of the two cell lines using gDNA and single-cell MDA product as reference were compared.[Result] An extremely lower call rate (3.2 ± 1.2)% in the negative control group was observed compared to the experiment groups.When the single-cell MDA product was used as reference,the standard deviations of Log2 (signal intensity ratio) were significantly decreased in both groups,compared with when the gDNA as reference (P ＝ 0.004).Through CNAT analytic software,some specific chromosomes (16,17,19,and 22) presented obvious preferential amplification (PA) when the gDNA was used as reference,but this PA could be eliminated when single-cell MDA product was used as reference.[Conclusion] 10 k 2.0 SNP mapping array in combination with MDA could be a quick,highly efficient and accurate method to detect aneuploidy in single cells.
