应用同种动脉治疗主动脉根部病变

报告５例采用同种动脉（ＨＡＶ）治疗５例主动脉根部病变（主动脉瓣狭窄１例，关闭不全４例）。男３例，女２例；年龄１３～４７岁。病因为细菌性心内膜炎２例（包括先天主动脉瓣二瓣化畸型１例），Ｍａｒｆａｎ综合征２例，风湿性主动脉瓣关闭不全１例。术中采用同种主动脉全根置换３例（Ｂｅｎｔａｌｌ手术），其中１例用ＨＡＶ上的二尖瓣前叶加宽主动脉瓣环（Ｍａｎｏｕｇｕｉａｎ手术），余２例用自体肺动脉移置主动脉根部，另取同种肺动脉做原位移置（Ｒｏｓｓ手术）。结果死亡１冽，４例存活，且无并发症发生。术后超声心动图提示主动脉根部良好，无主动脉瓣反流。随访２．５～３．５年疗效满意。     

Fabrication of porous hollow silica nanoparticles and their applications in drug release control.

Preparation and characterization of porous hollow silica nanoparticles (PHSN) for controlled release applications were investigated. Through orthogonally designed experiments, the optimal synthesis conditions for the preparation of PHSN were obtained and the produced PHSN were characterized by BET, SEM, TEM and IR. Scanning and transmission electron microscopy images revealed their hollow shell-core structure and also demonstrated that the size and shape of PHSN are determined by the templating CaCO3 nanoparticles. The produced PHSN were applied as a carrier to study the controlled release behaviors of Brilliant Blue F (BB), which was used as a model drug. Being loaded into the inner core and on the surfaces of the nanoparticles, BB was released slowly into a bulk solution for about 1140 min as compared to only 10 min for the normal SiO2 nanoparticles, thus exhibited a typical sustained release pattern without any burst effect. In addition, higher BET of the carriers, lower pH value and lower temperature prolonged BB release from PHSN, while stirring speed showed little influence on the release behavior. It showed that PHSN have a promising future in controlled drug delivery applications.     

运用市场手段实现医药自然分开的理论探讨

回顾了韩国、我国台湾和大陆实行医药分开改革的过程,认为我国以往的相关改革陷入了“管制”的思维误区。认为通过制度设计,创造医疗机构门诊处方自由流动的环境,依靠市场竞争形成处方流向结构多元化,可以实现医药自然分开状态。提出了“医药自然分开”、“处方流向结构”和“处方分散度”等新概念。     

北京农村居民健康状况及卫生服务需求调查

目的了解北京农村居民健康状况及卫生服务需求特点。方法从昌平区、顺义区、大兴区、房山区随机抽取25～64岁农民1605人进行统一问卷调查。结果农民高血压自报患病率为22．4％，超重和肥胖率为56．1％；现在吸烟率为34．4％，缺乏运动率为41．6％；家庭主要经济支出为学生上学(35．3％)，建房(25．4％)和疾病(21．2％)；54．9％家庭医疗费用支出占总收入的10％以上；最关心的健康问题主要是慢性疾病防治(70．2％)；最希望获得的健康知识是慢性病预防知识(72％)；希望获得健康知识的途径是广播和电视(81％)；家庭最希望获得的医疗保健服务是方便看病和获得药物(73．8％)。结论慢性病给农民带来沉重负担，并成为农民关心的主要健康问题。     

胸水军团菌抗体检测的探讨—附军团菌肺炎合并胸水一例报告

我们应用试管凝集法及酶联免疫吸附试验方法检测了５０例非军团菌感染病人胸水中嗜肺军团菌１、６型抗体及病人血清中相应抗体。发现在这些普通病人胸水中也存在一定的嗜肺军团菌抗体滴度，并计算出这些抗体的９９％上限滴度（Ｘ＋２．３２６Ｓ）。为今后检测嗜肺军团菌感染病人的胸水提供了一个参比对照指标。实验后期，我们检测了一例军团菌肺炎病人，其胸水中Ｌｐ１型抗体滴度远远超过了该上限值，并高于其自身血清中相应抗体。     

替米沙坦治疗原发性高血压的疗效和安全性

目的 :观察替米沙坦治疗原发性高血压的疗效和安全性。方法 :进行随机、双盲、双模拟、平行分组对照试验。符合条件的轻中度高血压患者随机分为 2组 :替米沙坦组和氯沙坦组。每天一次口服替米沙坦 40mg或氯沙坦 5 0mg ,每 2周随访 1次。 4周后 ,如患者舒张压 (DBP)≥ 90mmHg则增加剂量 ,每天一次口服替米沙坦 80mg或氯沙坦 10 0mg。治疗前后分别查心电图 ,血、尿常规 ,血生化检查和常规查体。 结果 :(1)治疗 8周末 ,替米沙坦组和氯沙坦组患者的DBP均显著降低 ,2组下降幅度相似 (11.9mmHgvs 10 .4mmHg) ;(2 )治疗8周末 ,替米沙坦组收缩压 (SBP)下降幅度稍大于氯沙坦组 (9.5mmHgvs 6.2mmHg) ;(3 )替米沙坦降压有效率为 83 .3 % ,稍高于氯沙坦组 69.2 % ,无统计学差异 ;(4 ) 2组的不良事件发生率相似 (替米沙坦组 3 3 .3 % ,氯沙坦组 3 4.6% )。最常见的不良事件是头晕、头痛 ,多为轻度 ,可迅速缓解。结论 :替米沙坦 40mg～ 80mg ,每天一次口服治疗轻中度高血压安全有效     

Study on Tongkuaixiao Babu plaster in treating cancer pain

Objective: To explore the efficacy of Tongkuaixiao Babu plaster (TKXBBP) in treating cancer pain.Methods: In the clinical observation, sixty-five patients with moderate or severe cancer pain were randomly divided into two groups: 32 in the treated group (TKXBBP group) and 33 in the control group (Bucinnazine group). The therapeutic effects in relieving pain, improving quality of life (QOL), and the rate of satisfaction the patients felt of the two groups were compared respectively. Results: TKXBBP was effective in treating cancer pain. There wasn’t any statistically significant difference in total effective rate (P>0.05), but the statistical difference was significant in obvious remission rate (P<0.05) between the treated and control group, and the effect on serious pain shown in the treated group was better than that of the control group (P<0. 05). The difference in the initiation time of relieving cancer pain was insignificant (P>0.05), while in the remission period, the treated group showed its treatment was obviously superior to that of the control group (P<0.05). TKXBBP showed better effect in the improvement of QOL (P<0.05) and satisfaction rate, with significant difference between the treated and the control groups (P<0.01).Conclusion: TKXBBPs effect in treating cancer pain was obvious, its application was safe and convenient. It was shown that the external treatment with this kind of Chinese medicine had great advantage in treating cancer pain.     

复方通络中药改善肥胖患者血管内皮细胞功能障碍研究

目的观察复方通络中药对单纯性肥胖患者血管内皮依赖性舒张功能障碍的干预效应，探讨其作用机制。方法应用高分辨血管超声检查选择血管内皮依赖性舒张功能障碍[以血流介导的肱动脉扩张率（FMD）表示]肥胖患者（65例），随机分为通络中药治疗组和对照组。治疗组32例，对照组33例。治疗组给予辛香疏络2号胶囊，3g／次，每日3次；对照组给予淀粉胶囊，3g／次，每日3次。共用药12周，分别测定用药前后FMD、肱动脉内径（D0），同时检测辛香疏络2号治疗前后患者血清总胆固醇（TC）、三酰甘油（TG）的变化。结果治疗后治疗组FMD较对照组明显增加（P〈0．01），TC、TG较治疗前及对照组明显下降（P〈0．01）。结论复方通络中药辛香疏络2号胶囊可明显改善肥胖患者血管内皮障碍，调节血脂可能是其改善血管内皮功能机制之一。
