复方18甲基炔诺酮透皮控释传递系统的LNG人体药物动力学与药效学评价

复方18甲基炔诺酮/雌二醇透皮控释传递系统(LNG/E_2 TCDS)能同时恒速释放低剂量的LNG和E_2,在1周内维持一个平稳而有效的LNG血药浓度。药动学与药效学研究证明,该系统释放的LNG能达到血清LNG目标水平,产生有效的排卵抑制(6/6)。LNG/E_2 TCDS可望发展成为一种安全、有效、非侵入性的新型生育调节避孕制剂。     

扩大的椎板间开窗治疗腰椎间盘突出伴侧隐窝狭窄（附140例报告）

本组采用的扩大的椎板开窗术治疗腰椎间盘突出合并侧隐窝狭窄140例。结果全部优良，与适应症严格选择和手术损伤小有关。强调切除卡压神经根的侧隐窝后壁外侧，即上关节突的冠状面．不失其脊椎三柱系统的三角结构。俯卧位头低足高，可减少硬膜囊张力避免负损伤。切除棘突下椎板时，用神经拉勾代替神经剥离器易于分离黄韧带，用90度的椎板咬骨钳斜向棘突方向，可满意地切除该部份椎板黄韧带，并可刮切椎板内层。神经根周围滴入醋酸炎舒松A2-3ml，术后疼痛锐减。减压窗口置盖明胶海绵有其争议，作者实践体会放置害处不大，要求病人有“护腰”意识。     

高强度超声对犬前列腺组织损伤的实验研究

目的　探讨经尿道高强度超声 (transurethralhighintensityultrasound ,TUHIU)治疗良性前列腺增生症 (benignprostatichyperplasia ,BPH)的有效性和可行性。方法　对犬前列腺进行TUHIU辐照处理 ,辐照后不同时期处死动物以观察其急性、亚急性和慢性期大体及组织病理变化。同时观察辐照前后影像学变化。结果　TUHIU辐照前前列腺部尿道平均最大宽度为 0 66± 0 12 ( x±s)cm ,辐照 3周后前列腺部尿道平均最大宽度为 2 11± 1 0 7cm ,较辐照前显著增宽。辐照后可见靶区内尿道周围腺体发生凝固性坏死 ,3 0～ 60天后坏死组织脱落尿道呈囊腔状。光、电镜下均可见腺上皮及基质细胞发生均匀性凝固性坏死。辐照后经腹B超示前列腺内部出现液性暗区 ,前列腺呈囊性改变。辐照后即刻各犬均出现短暂性尿潴留、尿频、尿线变细 ,1月后恢复正常。结论　TUHIU可破坏前列腺组织 ,明显增加前列腺部尿道宽度。     

双腔右心室(附四例报告)

本文对我院1983～1985年经手术证实的4例双腔右心室病例,进行了分析讨论。本病除右心导管检查发现肺动脉与右心室有压力阶差移行曲线、右心造影时心腔内显示充盈缺损、超声心动图等检查有助于诊断外,X线心脏平片、心电图、临床症状、体征均无特异性的诊断价值。认为,由于本病多合并室缺,因此对室缺修补时,应常规探查右心室腔,以免漏诊。另外,对本病与法乐氏四联症的鉴别作了较详细的讨论。     

自制新荧光剂EPQS的性能测试

作者对自制新荧光剂EPQS进行了性能测试。结果:量子产率为0.21;最大激发波长和荧光波长分别为375nm和484nm,stokes位移109nm;检测生物化合物常用的缓冲溶液对荧光峰位无影响,对荧光强度影响很小;温度的影响也小(18～43℃,FRI61.5～58.1),PH的影响也不大。说明EPQS不仅荧光参数好,而且稳定性也好。适合在较广泛的环境条件下使用。     

Breast Volume Measurement in Young Chinese Women and Clinical Applications

The authors carried out research on breast volume and body surface anatomy of 125 women. As a result, an average breast volume for Chinese women was obtained (325.36 ± 12.66 ml), and a table with several linear equations for calculating breast volume was derived. The authors applied these results to their clinical work and succeeded in making mammaplasty more precise in 178 patients.     

Protection of chickens against highly lethal H5N1 and H7N1 avian influenza viruses with a recombinant fowlpox virus co-expressing H5 haemagglutinin and N1 neuraminidase genes

Inactivated whole avian influenza virus (AIV) vaccine provides protection against homologous haemagglutinin (HA) subtype virus, but poor protection against a heterologous HA virus. Moreover, it induces chickens to produce antibodies to cross-reactive antigens, especially nucleoprotein, which is limits AIV serological surveillance. In this study, a recombinant fowlpox virus co-expressing HA (H5 subtype) and NA (N1 subtype) genes of AIV was evaluated for its ability to protect chickens against intramuscular challenge with a lethal dose of highly pathogenic (HP) AIV. Susceptible chickens were also vaccinated by wing-web puncture with the parent fowlpox vaccine virus. Following challenge 4 weeks later with HPAIV, all chickens vaccinated with recombinant virus were protected, while the chickens vaccinated with either the unaltered parent fowlpox vaccine virus or unvaccinated controls experienced 100% mortality following challenge. This protection was accompanied by the high levels of specific antibody to the respective components of the recombinant vaccine. The above results showed that rFPV-HA-NA could be a potential vaccine to replace current inactivated vaccines for preventing AI.
