OBJECTIVE: To investigate the effect of Jianpiyiqi granule, prepared according to a Traditional Chinese Medicine(TCM) formula, on the ocular type of myasthenia gravis(MG) caused by a defect in synaptic transmission at the neuromuscular ***: A total of 155 children with ocular MG were recruited from January 2008 to January *** individuals received ineffective glucocorticoid treatment prior to admission, and were given Jianpiyiqi granules(two doses per day) for 12 *** levels of acetylcholine receptor autoantibodies(ACh R-Ab), cytokines, immune parameters and clinical score were ***: After intervention with Jianpiyiqi granule for 12 months, the levels of cytokines [including interleukin(IL)-6, IL-12, IL-17], immune parameters[including immunoglobulin G(Ig G), Ig M, free triiodothyronine, free thyroxine] and ACh R-Ab were sig-nificantly decreased(P = 0.042, P = 0.049, P = 0.011,P = 0.02, P = 0.04, P = 0.03, P = 0.01; F = 21.60, P =0.000). In contrast, IL-4 levels were significantly increased(P = 0.049). The absolute clinical score after treatment declined significantly compared with before treatment(F = 33.24, P = 0.000). The effective cure rate and the total effective rate gradually increased to a maximum of 149(96.2%) and 151(97.4%) in MG patients after 12 months of treatment, ***: The Jianpiyiqi granule treatment lowered ACh R-Ab levels and improved cytokine and other immune parameter levels, which suggests that the granule could be an ancillary treatment for ocular MG in children caused by a defect in synaptic transmission at the neuromuscular junction.

Light hydrocarbons （LHs） are one of the main petroleum fractions in crude oils, and carry much infor- mation regarding the genetic origin and alteration of crude oils. But secondary alterations--especially biodegrada- tion--have a significant effect on the composition of LHs in crude oils. Because most of the LHs affected in oils underwent only slight biodegradation （rank 1 on the biodegradation scale）, the variation of LHs can be used to describe more the refined features of biodegradation. Here, 23 crude oils from the Dawanqi Oilfield in the Tarim Basin, NW China, eleven of which have been biodegraded to different extents, were analyzed in order to investigate the effect of slight to minor biodegradation on C6--C7 LHs. The study results showed that biodegradation resulted in the prior depletion of straight-chained alkanes, followed by branched alkanes. In slight and minor biodegraded oils, such biodegradation scale could not sufficiently affect C6- C7 cycloalkanes. For branched C6--C7 alkanes, generally, monomethylalkanes are biodegraded earlier than dimethylalkanes and trimethylalkanes, which indicates that branched alkanes are more resistant to biodegradation, with the increase of substituted methyl groups on parent rings. The degree of alkylation is one of the primary controlling factors on the biodegradation of C6-Cv LHs. There is a particular case： although 2,2,3-trimethylbutane has a rela- tive higher alkylation degree, 2,2-dimethylpentane is more resistant to biodegradation than 2,2,3-trimethylbutane. 2,2- Dimethylpentane is the most resistant to biodegradation in branched C6-C7 alkanes. Furthermore, the 2-methylpen- tane/3-methylpentane and 2-methylhexane/3-methylhexane ratios decreased steadily with increasing biodegradation, which implies that isomers of bilateral methyl groups are more prone to bacterial attack relative to mid-chain iso- mers. The position of the alkyls on the carbon skeleton is also one of the critical factors controlling the rate of b

基于半经验的Gupta多体势,采用遗传算法及分子动力学淬火算法,系统研究了(FeMo)m(m=38及55)双金属团簇的基态结构及其能量.结果表明:对于Fe_(n)Mo_(38-n)(n=0-38)团簇,随Fe原子数的增加,Fe原子优先占据团簇表面再占据内部,其基态构型存在类O_(h)结构、类I_(h)结构和无序结构间的竞争.对于Fe_(n)Mo_(55-n)(n=0-55)团簇,随Fe原子数的增加,Fe原子优先占据团簇中心位置,再依次占据表面顶点、棱边和次外层,双金属团簇基态构型主要体现为在Mackay二十面体基础上的结构畸变.Fe_(24)Mo_(14),Fe_(13)Mo_(42)和Fe_(43)Mo_(12)为幻数结构团簇,研究发现双金属团簇幻数成因不能通过单质团簇常用的平均配位数和平均键长模型解释,它更多的归咎于组分效应导致的结构高对称性.
