一阶导数高速脉冲极谱法用于盐酸普鲁卡因的定量分析

研究了一阶导数高速脉冲极谱法,并运用于盐酸普鲁卡因及其注射制剂的定量分析。在-0.04 V(对 Ag/AgCl)处出现的良好导数峰,于1.0～6.0×10~(-4)mol/L 范围内,导数峰电流与浓度呈线性关系。检测限为3.0×10~(-8)mol/L。操作简便、快速、灵敏,结果准确。     

Depressed levels of circulating menaquinones in patients with osteoporotic fractures of the spine and femoral neck

Vitamin K₁ functions in the conversion of glutamate residues, present in certain bone peptides, into the putatively active γ-carboxyglutamate form. We have shown previously that the circulating levels of vitamin K₁ are depressed in osteoporotic patients. However, it is known that menaquinones (vitamin K₂:MK) may be more effective than vitamin K₁ in this conversion of the inactive to active form of glutamate residues. A procedure for measuring such menaquinones has now demonstrated a marked deficiency of MK-7 and MK-8 in patients with osteoporotic fractures. It is suggested that estimates of circulating levels of K₁, MK-7, and MK-8 might provide a biochemical risk marker of osteoporotic fractures.     

细针抽吸活检术诊断脾结核

脾结核发病较少见，临床症状表现也不典型，常易误诊为其他病变如淋巴瘤、脓肿等，影像表现未见特异征象，极易误诊。现将我院收治的3例脾结核临床特点、影像表现进行介绍。特别是在B超或CT引导下的细针抽吸活检术应用，旨在提高对本病认识、及时正确诊断，避免误诊。     

神经干细胞静脉移植治疗脊髓损伤的实验研究

[目的]观察神经干细胞静脉移植对损伤大鼠脊髓功能的治疗作用。[方法]取孕14—16dSD胎鼠的脑室下区组织，体外培养后鉴定细胞。制作脊髓全切模型，伤后1周将Brdu标记好的神经干细胞通过尾静脉注射移植到大鼠体内，移植后及8周行皮层体感诱发电位（CSEP）检测和BBB功能评分，并留损伤脊髓处作病理切片及免疫组化染色。[结果]（1）移植后8周BBB评分损伤组、移植组都有所恢复，但都未达到正常水平，移植组恢复较好；（2）模型制作后，CSEP波均消失，细胞移植后8周移植组的波形有不同程度的恢复，但潜伏期延长；（3）移植组大鼠脊髓损伤处存在大量Brdu染色阳性细胞，表明移植的细胞在体内可到达损伤脊髓处并能存活；脊髓损伤部位NF-200及GFAP染色阳性的细胞表明移植的细胞可以分化为具有神经元和胶质细胞特性的细胞。[结论]静脉移植的神经干细胞能到达损伤区代替受损的神经元及神经胶质细胞，使损伤的脊髓功能得到一定程度的恢复。     

新肩三针穴位注射为主治疗肩手综合征的临床研究

目的评价新肩三针穴位注射治疗脑卒中后肩手综合征的临床疗效。方法采用随机对照的方法,将72例符合纳入标准的患者分为治疗组(针刺 新肩三针穴位注射)和对照组(单纯用针刺)。用脑卒中临床神经功能缺损程度评分量表,肩关节疾患治疗成绩判定标准和手掌手指功能评价进行临床疗效评定。结果治疗组疗效明显优于对照组,差异有统计学意义(P<0.05)。结论新肩三针穴位注射是治疗脑卒中后肩手综合征的有效治疗方法。

目的观察隔姜灸配合穴位注射治疗支气管哮喘的临床疗效。方法将88例患者随机分为3组,观察组30例采用隔姜灸配合穴位注射治疗,对照组29例采用隔姜灸配合0.9%生理盐水穴位注射治疗,针刺组29例采用针刺治疗。30天后统计疗效。结果与结论观察组在降低血清IgE值及临床疗效上明显优于对照组和针刺组。     

苦碟子注射液治疗突发性聋疗效的观察

目的:探讨苦碟子注射液治疗突发性聋的效果。方法:随机将120例患者分为两组,治疗组60例,予以苦碟子注射液治疗;对照组60例,予以低分子右旋糖酐联合复方丹参注射液治疗。结果:治疗组治疗耳聋、耳鸣总有效率分别为88.33%、82.86%,对照组分别为68.33%、62.50%,治疗组耳聋、耳鸣总有效率均明显高于对照组(P<0.05)。结论:苦碟子注射液治疗突发性聋疗效好且安全可靠,无明显不良反应。     

大陷胸汤灌肠治疗流出急性肾衰的观察与护理

目的 探讨中药大陷胸汤高位保留灌肠对流行性出血热（EHF）急性肾衰的治疗作用。方法 将60例EHF急性肾衰患者随机分为对照组与治疗组各30例，对照组予以常规治疗，治疗组在常规治疗的基础上加用大陷胸汤高位保留灌肠，观察两组患者治疗前后的疗效。结果 治疗组治愈23例，好转6例，无效1例，总有效率96．7％；对照组治愈17例，好转7例，无效6例，总有效率80．0％；两组疗效比较，有显著差异性p〈0．05（x^2=4．630）。结论 大陷胸汤高位保留灌肠治疗EHF急性肾衰疗效显著，且简便、安全、经济、病人乐于接受等优点。     

Morphology of corticotectal cells in the primary visual cortex of hooded rats

In primary visual cortex of hooded rats, pyramidal cells in layer V may be classified as long, medium, or short, on the basis of the layer in which the apical dendrite terminates. The present study determines which of these types of pyramidal cells project to the superior colliculus. Two different strategies were used to label corticotectal cells with horseradish peroxidase (HRP). In the first set of experiments, a large number of corticotectal cells were labeled by retrograde transport following injection of HRP into the superior colliculus. In the second set of experiments, single unit recording was used to identify corticotectal cells physiologically by antidromic activation from the superior colliculus. These cells were then impaled and labeled by intracellular iontophoresis of HRP. The results from both techniques suggest that only long pyramidal cells send an axon to the superior colliculus. These cells are distinguished by an apical dendrite that extends into layer I. We conclude that in hooded rats corticotectal cells in primary visual cortex are the long pyramids in layer V.
