Pharmacological action of Adenophora polysaccharides

Adenophora polysaccharides (AP), is an active principle extracted from the root of Adenophorae Potaninii Korsh originated in Gansu Province and isolated with boiling water(1). AP is isolated and purified from the crude drug by DEAE-cellulose and Sephadex G-200 column, with a white powder and mean molecular weight of 8.3 × 104 , and [α]D20of AP is 68(1). AP is only composed of glucose judging from the analysis of it with patina chromatography (PC) and gas chromatography-mass spectrometer (GC-MS) methods.The methylation analysis showed that AP is composed of (1→6) linked glucose residues. The measure of nuclear magnetic resonance imaging (NMR) 1H NMR and 14C NMR techniques further proved that AP is α(l→6) linked by Dglucose. The structure of AP is as follows: -[→6]α-D-Glu(1-)n→ (2).     

伽玛刀治疗功能性垂体瘤初步报告

目的 对伽玛刀治疗分泌型垂体瘤的疗效和并发症发生的相关因素进行探讨。方法 1997年9月至2001年11月，248例垂体瘤经伽玛刀治疗。其中．73例年龄在16至61岁的分泌型垂体瘤获得详细随访，53例为PRL型，11例GH型，2例为ACTH型，6例为PRL合并GH型，1例为PRL合并ACTH型。7例为术后复发和残留。23例曾接受过嗅隐亭治疗。平均肿瘤容积为5．83cm^3(0．14～25．20cm^3)。边缘剂量为8～35Gy。结果 平均随访时间21个月。36例(49.3％)内分泌恢复正常。内分泌恢复正常的比率3个月后1．4％，6个月后16．4％．1年后45．2％，2年后49．3％。3例(4、1％)发生垂体瘤功能低下。1例复发二次治疗。无病例发生视路受损。结论 伽玛刀治疗分泌型垂体瘤是安全有效的治疗方法。其长期疗效和并发症的发生仍需进一步的随访观察。     

聚氨酯避孕套临床前使用可行性和可接受性分析

目的 对使用新型聚氨酯(Pu)男用避孕套的可行性和可接受性进行初步观察。方法 对30对健康已婚夫妇为期6周360次使用国产PU避孕套的效果进行问卷调查。结果 避孕套总破裂率(临床破裂 非临床破裂)为2．22％，临床滑脱率为16．5％，使用观察期间无意外妊娠发生。结论 新型PU避孕套的破裂率和滑脱率分别相近于和高于报道的乳胶避孕套使用情况，感官指标反映PU避孕套具有良好的可接受性。     

Validation of the Taiwan Birth Registry using obstetric records.

BACKGROUND AND PURPOSE: Birth certificates are a major source of population-based data often used in maternal and child health research, but their value depends upon the level of accuracy of the data. The purpose of this study was to assess the validity of the birth registry data in Taiwan. METHODS: Obstetric records of a total of 2779 infants born at a municipal hospital in Taipei between 1995 and 1997 were abstracted and linked to the Taiwan Birth Registry (TBR). Concordance was presented by agreement percentages for various birth characteristics including gender, birth order, birth weight, and gestational age. Concordance was further assessed using Cohen's k and sensitivity/specificity for both birth weight and gestational age, with both variables categorized according to their customary definitions. RESULTS: Missing data for specific items in the TBR ranged from 0% (gender) to 1.6% (birth order). The birth registry accurately reported all 4 selected items, with the highest and lowest concordance percentage noted for gender (99.0%) and gestational age (88.3%), respectively. The level of agreement indicated by the Cohen's k statistic ranged from 0.92 to 0.96 for birth weight and gestational age when both variables were treated as categorical variables. CONCLUSIONS: The TBR showed a low rate of missing information and high levels of validity for the elements frequently used in maternal and child health research in Taiwan.

目的探讨心包置管在治疗创伤性心包压塞中的应用价值. 方法 1998年3月～2003年9月,我们对9例创伤性心包压塞在超声引导下穿刺积血心包,置入导管,通过导管抽出心包积血,然后及时引流心包内出血. 结果置管引流后,病人的压塞症状明显好转.4例在引流4～8 h内行心脏修补术,2例创伤好转后择期手术,2例引流后痊愈,1例因颅脑创伤严重而死亡. 结论该方法安全可靠,能迅速缓解创伤性心包压塞症状,为心脏修补手术创造较好的条件和较充分的时间,部分病人可以避免手术.     

心理支持疗法对机械通气患者应激反应的影响

目的 观察心理支持疗法(PST)对ICU患者机械通气应激反应的影响。方法 将34例连续机械通气时间在20h的清醒患者，随机分为采用标准的PST方法进行治疗的观察组和对照组，观察焦虑抑郁程度和应激反应改变情况。结果 对照组患者的焦虑抑郁程度明显高于观察组，部分应激反应激素水平升高幅度也明显大于观察组。结论 PST可通过缓解机械通气患者的焦虑抑郁等不良情绪状态减轻机械通气带来的各种心身应激反应，有利于提高机械通气治疗的有效性和安全性。
