清开灵注射液治疗SHR_(SP)出血性中风病的研究

实验结果显示，清开灵注射液能延长ＳＨＲＳＰ生存期和卒中后的存活时间，降低脑系数，减轻脑水肿，增强脑出血灶的吸收，促进肉芽组织增生，有利于病灶的修复；亦能使海马ＣＡ１区神经元损伤减轻脱失减少；神经元计数清开灵组较病理组明显增加（Ｐ＜０．０１）。提示清开灵对出血性中风的治疗作用机制是通过改善脑水肿，促进出血病灶的吸收修复，保护神经细胞而实现的。     

氧氟沙星葡萄糖注射液的抗菌作用

通过对氧氟沙星葡萄糖注射液体内外抗菌作用的研究,认为氧氟沙星葡萄糖注射液是一种抗菌谱广,抗菌活性强的抗菌药,它对革兰氏阳性菌的最小抑菌浓度范围为 0.8～0.3βg/ml,与氧氟沙星原料相比没有降低其药效。氧沙星葡萄糖注射液对革兰氏阳性菌的抗菌作用强于诺氟沙星注射液的4倍左右,对小鼠感染金黄色葡萄球菌(S.aureus)和肺炎杆菌(K.Pncumoniae)强3～6倍。     

清开灵治疗高血压脑出血术后高热、昏迷的临床研究

目的 探讨清开灵注射液对高血压脑出血术后高热、昏迷的疗效。方法 对117例脑出血术后昏迷、高热的患者在常规治疗的基础上，增加应用清开灵注射液来加强促醒、降温的效果，与对照组117例单纯常规治疗的患者相比较，进行一系列指标的观察。结果 清开灵治疗组在高热持续时间、昏迷时间、住院时间以及4周时日常生活能力(ADL)分级的对比等方面均优于对照组，而病死人数、不良反应方面两者无明显差异。结论 清开灵注射液能够明显缩短高血压脑出血患者术后高热、昏迷的持续时间，并能缩短病程，改善预后。

PMMA (polymethylmetacrylate) microspheres and stabilized hyaluronic acid as an injection laryngoplasty material for the treatment of glottal insufficiency: in vivo canine study

Both PMMA (polymethylmetacrylate) microspheres (PM) and stabilized hyaluronic acid (HA) are recently used for facial augmentation. The aim of this study was to test functional effect, durability, and safety of the injection of these two materials into true vocal folds, and test their availability as injection laryngoplasty materials in vivo canine model. The study was carried out with 16 beagle dogs (8 males and 8 females, average weight of 12.4 kg). No biological difference was detected between two groups; PM (Artecoll) injection and HA (Restylane) injection group. After inducing complete unilateral paralysis of the recurrent laryngeal nerve of the dogs, either PM or HA was injected into the paralyzed vocal fold. One, 3, 6, and 9 months after the injection, clinical outcomes and videostroboscopic findings were evaluated by investigators who were blind to the injection materials. Histological study and microscopic computerized augmentation dimension analysis were also performed. In HA injection group, up to 30% the HA was gradually resorbed over time. However, in PM group, the dimension of the augmented region after 9 months was similar to that after 1 month. In both groups, the mucosal waves of the vocal folds decreased in amplitude and periodicity, but they were still well detected during the follow-up periods. Acute immune reaction to HA was not detected, but some degree of foreign body reaction occurred in PM injection group. Both PM and HA are safe and relatively durable in vocal folds and they are considered as useful candidates for injection laryngoplasty.     

Bacteremia after injection of esophageal varices

Summary Elective sclerotherapy for esophageal varices produces bacteremia in 4% to 53% of patients. The clinical importance of this phenomenon is uncertain. This study was undertaken to re-assess the incidence and clinical relevance of post-sclerotherapy bacteremia. Blood cultures were taken prior to and at 5 min and 4 h after endoscopy in 50 patients for whom sclerotherapy was planned. In the 41 patients in whom varices were injected, positive cultures were obtained 5 min after sclerotherapy in only 4 patients (10%) and all but 1 patient had other possible causes of bacteremia. After 4 h, all blood cultures were sterile. No infective complications were identified. Bacteremia appears to be an infrequent and transient event after elective sclerotherapy. Only patients with prosthetic heart valves or endocardial abnormalities require antibiotic prophylaxis.

多相脂质体139注射液化学稳定性的研究

本文根据多相脂质体139注射液的处方组成及其主要有效成份的结构和性质,设计了利用碘量法测定139注射液中不饱和度(双键氧化)和电导滴定法测定酸度的变化规律,得出包封于脂质体中药物的氧化反应符合零级反应速度方程,载体主要成分的脂键水解反应也符合零级反应速度方程;并求得了多相脂质体139注射液中双键氧化反应与载体成分的水解反应的活化能和反应速度常数;预测了药物贮存期 t_(0.9)~(25℃)=2.63年。同时,本文提出了利用电导滴定曲线确定在缓冲溶液及多种化学成份的复杂体系中弱酸盐滴定终点的新方法。
