Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction, but whether naajor ozonated autohelnotherapy affects remote in）ury remains poorly understood. Here, we assumed that major ozonated autohemotherapy contributes to recovery of clinical function, possibly by reducing remote injury after acute cerebral infarction. Sixty acute cerebral infarction patients aged 30-80 years were equally and randomly allocated to ozone treatment and control groups. Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy （47 mg/l, 100 ml ozone） for 10 ± 2 days. Patients in the control group received medical treatment only. National Institutes of Health Stroke Scale score, modified Rankin scale score, and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased, brain function improved, clinical efficiency significantly increased, and no obvious adverse reactions detected in the ozone treatment group compared with the control group. These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing re,note injury, and additionally, exhibits high safety.

Salidroside(SAl) is a glucoside of tyrosol and a key constituent of Rhodiola rosea l. The diverse pharmacological activities of SAl include anti-inflammatory, cardioprotective, and neuroprotective effects(1)Our previous investigation showed that the anti-aging effects of SAl involve reductions of the levels of advanced glycation end products in a D-galactose induced mouse model(2)Additionally.

Three parallel anaerobic-anoxic/anaerobic-aerobic （AN/ao） processes were developed to enrich denitrifying phosphorus removal bacteria （DPB） for low strength wastewater treatment. The main body of the parallel AN/ao process consists of an AN （anaerobic-anoxic） process and an ao （anaerobic-aerobic） process. In the ao process, the common phosphorus accumulating organisms （Paos） was dominate, while in the AN process, DPB was dominate, The volume of anaerobic zone（Vana）：anoxie zone（Vano）： aerobic zone （Vaer） for the parallel AN/ao process is 1：1：1 in contrast with a Vana：Vaer and Vano：Vaer of 1：2 and 1：4 for a traditional biological nutrient removal process （BNR）. Process 3 excels in the 3 processes on the basis of COD, TN and TP removal. For 4 month operation, the effluent COD concentration of process 3 did not exceed 60 mg/l; the effluent TN concentration of process 3 was lower than 15 mg/l; and the effluent TP concentration of process 3 was lower than 1 mg/l.

以含l-苯丙氨酸铜配位络合物的溶液作为手性流动相,采用反相高效液相色谱法拆分了非衍生苯甘氨酸对映体,使用质谱对拆分组分进行了结构鉴定,得到了拆分组分的化学结构,用量子化学计算预测了该结构的最稳定构象.质谱实验结果表明,拆分组分是一对铜混合配体复合物离子,其中的一个配体是提供手性环境的流动相添加物(l-苯丙氨酸),另一配体是待拆分物质的某一构型对映体,这对铜混合配体复合物离子本质上属于非对映异构体.在色谱分离实验中还考察了手性流动相pH值、甲醇含量以及l-苯丙氨酸与Cu2+的摩尔比等因素对分离效果的影响.

Snapping scapula is an uncommon condition described as palpable, audible, or painful crepitus of the scapula that causes diminished quality of life.l Until now it is still a largely under-recognized problem because of its diverse causes. The etiology of the problem is mainly divided into three major categories： bursitis, muscle abnormality, and bony or soft-tissue abnormality.

为了研究线圈脉冲电流参数对破甲弹金属射流箍缩特性的影响,提出了均匀线圈中脉冲电流作用下不均匀粗细金属射流磁感应强度、感应电流密度及箍缩电磁力分布的理论模型,建立了线圈与金属射流作用的有限元模型,分析了励磁线圈中所施加脉冲电流参数对金属射流的影响规律。结果表明,随着励磁线圈中所施加脉冲电流幅值的增大,金属射流中的感应电流密度、磁感应强度及电磁力也随之增大,励磁线圈中所施加的脉冲电流幅值Jmax≥1×1010 A/m2,才能保证金属射流可靠变形;随着励磁线圈中所施加脉冲电流频率的增加,金属射流中的感应电流密度、磁感应强度及电磁力整体均呈现一定程度的趋肤效应,且在一定的频率范围内,趋肤层逐渐变薄,分析得知,当励磁线圈中脉冲电流的频率满足50kHz≤f≤100kHz时,就能够保证金属射流发生有效变形,进而延缓金属射流箍缩直至断裂的过程。

【目的】松树蜂Sirex noctilio Fabricius是国际重大林业检疫性害虫,新渡户树蜂Sirex nitobei Matsumura是我国土著种,分布广泛;两者在我国局部地区共同危害樟子松Pinus sylvestris *** litv。本文根据种群生态位的相关理论对两种害虫在樟子松人工林内的危害情况、空间分布格局及时间和空间生态位进行研究,探讨外来入侵种与土著种的种间关系,以期指导外来有害生物的防治工作。【方法】林间踏查选择10块样地,连续2年进行每木检尺,采用分布型指数法判断两种树蜂的种群空间分布格局。记录两种树蜂羽化期和羽化数量,统计羽化孔相对位置,定量描述两者种群之间的共存机制。【结果】两种树蜂在林间为聚集分布,主要受害木的胸径集中在16.00~18.00 cm;松树蜂羽化期集中于6月底至9月初,新渡户树蜂于8月底至9月底,初步推断在研究林分中,松树蜂的当年侵入时间早于新渡户树蜂;松树蜂的雌雄性比为0.604,新渡户树蜂的雌雄性比为0.174;两种害虫的空间生态位较分离。【结论】松树蜂在内蒙古通辽市金宝屯林场属于定殖初期,与土著种新渡户树蜂共同危害樟子松,两者在林间的可利用资源丰富且虫口密度较低,导致空间生态位分离,初步推测不存在强烈的竞争关系;且各项空间分布型指标符合聚集分布。

利用非线性动力学软件lS-DYNA,对聚能射流平行入射大气/钢靶板交界处的侵彻过程进行了数值模拟。通过分析数值模拟过程和结果,讨论了聚能射流头部速度和碰撞出口处横向速度的变化规律。结果表明:大气/钢靶板交界处不仅降低了聚能射流头部的轴向速度,而且使射流头部产生横向偏移,最大速度达到约1.8km/s;后续射流横向偏移速度逐渐减小,导致聚能射流提前断裂,未能形成连续侵彻。因此,大气/钢靶板交界处对聚能射流的头部起到了明显的干扰作用,可有效降低射流的侵彻能力。
