目的:探讨小切口正中神经松解术联合穴位注射序贯疗法治疗腕管综合征(CTS)的效果。方法:选择2021年1月—2023年1月钦州市第二人民医院收治的103例CTS患者作为研究对象。按照随机数表法分为对照组(n=52)和观察组(n=51),两组均进行小切口正中神经松解术治疗,对照组术后口服神经营养素药物治疗,观察组术后采用穴位注射序贯法治疗。比较两组治疗效果、腕关节综合征Levine评分及正中神经肌电图指标[感觉传导速度(SCV)、感觉神经动作电位波幅(SNAP)、运动神经末端运动潜伏期(DML)]。结果:观察组总有效率为98.00%,高于对照组的80.00%,差异有统计学意义(P<0.05)。治疗6个月后,两组严重程度、功能状态评分低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05)。治疗6个月后,两组SCV、SNAP均高于治疗前,DML低于治疗前,且观察组SCV、SNAP高于对照组,DML低于对照组,差异有统计学意义(P<0.05)。结论:小切口正中神经松解术联合穴位注射序贯疗法治疗CTS可有效提高其治疗效果,改善患者腕关节功能,促进神经恢复。

为探究超声联合碳酸氢钠处理对低盐狮子头品质的影响规律,以狮子头为研究对象,分析低盐(质量分数1%食盐)条件下碳酸氢钠和超声处理对狮子头pH值、色泽、蒸煮损失、加压损失、质构、感官和挥发性风味物质等指标的影响。结果表明:与1%食盐处理组相比,超声联合碳酸氢钠处理显著降低了狮子头红度值,但增加了亮度值和黄度值(Pz,z)-9,12-十八碳二烯酸-甲酯等酯类;1%食盐+碳酸氢钠处理组的关键性风味物质为醇类物质,包括苯乙醇、10-叠氮基-1-癸硫醇和3-甲基-1-丁醇;1%食盐+超声处理组的关键风味物质为己醛、壬醛等醛类物质;1%食盐+0.4%碳酸氢钠+超声处理组的关键性风味物质主要为戊醛、壬醛、己醛、3-甲基-1-丁醇、1-辛烯-3-醇、乙醇和乙酸乙酯,其中己醛和壬醛是其中最关键的风味物质,超声联合碳酸氢钠处理使得狮子头中风味物质组成更加丰富;感官评价结果表明,超声联合碳酸氢钠处理组的感官评分最高(43.52),显著高于1%食盐处理组(P0.05)。综上所述,1%食盐+0.4%碳酸氢钠+超声处理的狮子头品质与2%食盐处理组无显著差异,部分品质指标甚至显著提升,说明超声联合碳酸氢钠处理完全弥补了由食盐含量降低引起的产品保水性、质构及风味等品质劣变。

The compound(2) (C 24 H 20 NO 2ClS)(see Scheme 1) has been synthesized by reaction of 1, 5 benzothiazepine with chloroacetyl chloride and crystallized in the monoclinic system, space group P2 1/c, a=12.547(3), b=10.614(2), c=15.881(3) , β=105.91(3)°, V=2034.1(10) 3, D c =1.378 g/cm 3, z=4, F(000)=880, μ (Mo Kα) =0.311 mm -1 , R= 0.0510 and R w =0.0647 for 1953 observed reflections. Structure analysis reveals that the cycloaddition to β lactam is stereospecific reaction, the chloro and phenyl substituents in four membered ring are located on the same side of the nucleus. The conformation of seven membered ring in compound (2) is chair like.

Axonal myelination is an essential process for normal functioning of the vertebrate central nervous system. Proper formation of myelin sheaths around axons depends on the timely differentiation of oligodendrocytes. This differentiation occurs on a predictable schedule both in culture and during development. However, the timing mechanisms for oligodendrocyte differentiation during normal development have not been fully uncovered. Recent studies have identified a large number of regulatory factors, including cell-intrinsic factors and extracel- lular signals, that could control the timing of oligodendrocyte differentiation. Here we provide a mechanistic and critical review of the timing control of oligodendrocyte differentiation.

提出了一种含有光学参量放大器的复合腔磁系统。利用系统海森堡-郎之万演化方程和输入-输出关系研究了磁力诱导透明和快慢光效应。数值计算表明:当腔磁系统考虑磁振子-声子耦合时,出现双重透明窗口。磁振子-声子之间的耦合强度增强,透明窗口宽度变宽,深度加深。在系统中调控光学参量放大器的增益,吸收光谱在共振频率两侧出现不对称现象,吸收谱曲线的峰值随光学参量放大器增益的增加而变大。通过调节腔磁耦合强度,改变了吸收光谱和色散光谱的传输特性。此外,探测场的传输速率依赖于光学参量放大器的增益。腔磁系统的快慢光效应及其切换通过调控光学参量放大器得以实现。该研究结果可为量子光学操纵和量子信息存储的研究提供参考。
