The elucidation of vapor-liquid equilibrium (VLE) of the halogenated silane was necessary for the production of silicon derivatives, especially for methylvinyldichlorosilane, due to the lack of the relevant reports. Isobaric VLE for the system methyldichlorosilane-dimethyldichlorosilane-benzene and isobaric VLE of the three binary systems were measured with a new pump-ebulliometer at the pressure of 101.325 kPa. These binary compositions of the equilibrium vapor were calculated according to the Q function of molar excess Gibbs energy by the indirect method and the resulted VLE data agreed well with the thermodynamic consistency. Moreover, the experimental data were correlated with the Wilson, NRTL, Margules and van Laar equations by means of the least-squares fit, the acquired optimal interaction parameters were fitted to experimental vapor-liquid equilibrium data for binary systems. The binary parameters of Wilson equation were also used to calculate the bubble point temperature and the vapor phase composition for the ternary mixtures without any additional adjustment. The predicted vapor-liquid equilibrium for the ternary system was in a good agreement with the experimental results. The VLE of binary and multilateral systems provided essential theory for the production of the halogenated silane.

OBJECTIVETo establish a mathematical model of hepatitis C virus (HCV) replication and develop a working theory for antiviral therapy in order to understand the dynamics of HCV replication.

METHODSPeripheral blood cells of 4 hepatitis C patients were cultured. Quantities of the HCV were detected every 15 min by real-time PCR. The data were analyzed using SPSS software. A mathematical functional relationship between HCV RNA and the time lapse was established.

RESULTSThe quantity of HCV RNA declined and it fell into a mathematical model: Y=3E+0.8e(-0.5467x) (r=0.9547). The estimated virion half-life was 45 min on the average.

CONCLUSIONSThe decline of HCV RNA in the blood is not of a linear trend and the HCV RNA lasts a longer time although the speed of the decline is faster than that in vivo.

Objective To assess the effectiveness of unrelated donor (URD) allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of severe aplastic anemia (SAA),and the difference between URD allo-HSCT and matched sibling donor (MSD) allo-HSCT.Methods According to the source of donors,the SAA patients subject to allo-HSCT were divided into MSD allo-HSCT group (MSD group) and URD allo-HSCT group (URD group) from October 2001 to December 2016 in Henan Cancer Hospital.The efficacy and transplantation related complications were compared between two groups.Results There were no statistically significant differences in hematopoietic reconstitution and graft rejection between two groups.The incidence of grade Ⅱ-Ⅳ acute GVHD and chronic GVHD was higher in the URD group than in the MSD group (30.76％ vs.8.57％,P =0.026;26.92％ vs.5.71％,P =0.021).However,other transplant-related complications including pulmonary complications and hemorrhagic cystitis,incidence of EBV and CMV reactivation and venous occlusive disease showed no significant difference between two groups.The estimated 5-year over survival was (73.6 ± 8.7) ％ in the MSD group and (72.7 ± 9.5) ％ in the URD group (P =0.878).There was no significant difference in 5-year disease-free survival between two groups (73.6 ± 8.7％ vs.70.3 ± 10.2,P =0.668).Conclusion URD-HSCT is a novel treatment approach and could be considered as first-line therapy in selected patients without MSD.

Objective To observe expression of neuron specific enolase (NSE) gene in the brain of rats induced by iodine excess. Methods One hundred and fifty one-month weaning Wistar rats were divided into ten groups according to 5 × 2 factorial experiment. Rats were fed with normal feedstuff and water of a series of iodine concentration by adding potassium iodide respectively: norrmal iodine (NI), five-fold high iodine (5HI), ten-fold high iodine(10HI), fifty-fold high iodine(50HI) and one hundred-fold iodine(100HI). After these rats were fed for three or six months, rat serum thyroid hormones were measured by radioimmunoassay including TT4, TT3, FT4, FT3, rT3 and the mRNA level of NSE in rat brain tissue was studied using RT-PCR technique. Results The levels of serum TT4 and TT3 were significantly different in five iodine level groups(F values were 18.867,27.287, both P < 0.01). The interaction between time and iodine level in TT4 was significant in our study(F values were 2.486, P < 0.05). The levels of TT4 and TT3 of 100 HI group at third and sixth month were lower than those of NI, 5HI, 10HI, 50HI groups in the same period (all P < 0.01). The levels of serum FT4, FT3 and rT3 were significantly different at different time(F values were 4.968,27.046,59.776 respectively, P < 0.05 or < 0.01) and in different iodine level groups(F values were 33.058,28.420,17.482 respectively, all P < 0.01). Moreover, the interaction between time and iodine level in FT3 and rT3 was significant in our study(F values were 6.894,5.233 respectively, both P < 0.01). FT4, FT3 and rT3 in 100HI group were lower than that of other iodine dosage groups at the same time (P < 0.05 or < 0.01). The levels of NSE mRNA in brain tissue was significantly different in five iodine level groups (F values were 29.006, P < 0.05). The levels of mRNA NSE of 100HI group in both three and six months (0.61 ± 0.19,0.61 ± 0.22) were all lower than that of any other groups[NI(0.73±0.13 and 0.72 ±0.26), 5HI (0.72 ± 0.15 and 0.72±0.16), 10HI (0.73 ±0.32 and 0.70±0.13), 50HI(0.71±0.18 and 0.69±0.31), all P < 0.05]. The results of correlation analyses show that the levels of serum FT3 and FT4 had correlations with the levels of NSE mRNA (P < 0.05) both in three and six months(r values were 0.987, 0.969 in three month, and 0.890, 0.910 in six month respectively). Conclusions The expression of NSE gene can tolerant the excess of iodine to a certain extent. Exposure to heavy excess iodine(100HI) can decrease the mRNA level of NSE gene. FT4 and FT3 may both have important roles on the regulation of NSE mRNA induced by excess iodine.
