ATP和SNP控制性降压对血流动力学的影响

对比研究三磷酸腺苷（ＡＴＰ）和硝普钠（ＳＮＰ）控制性降压对氯胺酮麻醉犬血流动力学的影响。选择犬１４只，随机分为ＡＴＰ组和ＳＮＰ组，由股静脉持续输入ＡＴＰ和ＳＮＰ使ＭＡＰ降低３０％￣４０％，维持３０ｍｉｎ，分别于降压前、降压后１５ｍｉｎ、３０ｍｉｎ及停止降压后１５ｍｉｎ用Ｓｗａｎ－Ｇａｎｚ漂浮导管测定血流动力学指标。结果表明，ＡＴＰ、ＳＮＰ降压期间ＳＶＲ、ＬＶＳＷ显著降低，ＣＯ、ＰＣＷＰ、ＳＶ、ＲＶ

深低温冷冻保存家兔性腺器官的研究

自１９９２年７月开始行深低温（－１９６℃）冷冻保存兔性腺研究。冷冻睾丸３６个，１５天后解冻，完好率９１．７％，其中２０个行器官移植，睾丸接通血管均即时建立血循环。４只兔的冷冻睾丸自体移植后，每次采精７４０．６±１８９０．４万个。２只兔的冷冻睾丸异体移植后，每次采精６３．４±３７．７万个。冷冻兔卵巢１４个，１５天后解冻，完好率９２．９％，其中８个行器官移植，卵巢接通血管均即时建立血循环，术后雌二醇水平为２．７２～１２７．３ｐｍｏｌ／Ｌ。冷冻睾丸及卵巢移植一段时间后病理切片证实睾丸及卵巢组织存活。     

宣肺清热颗粒剂稳定性研究

目的:研究宣肺清热颗粒剂中橙皮甙热稳定性变化,为该颗粒剂有效期的确定、制剂生产、贮存条什提供实验参考依据。方法:采用加速实验法对橙皮甙热稳定性进行研究,用甲醇超声提取样品,HPLC进行含量测定。根据Arrhenius公式处理数据。结果:Arrhenius公式得室温下的速度常数K298=3.38×10-5/h,得出常温下该颗粒剂以橙皮甙为指标的有效期为3.6年。结论:宣肺清热颗粒剂稳定性好,初步符合中药稳定性要求。

Anatomic and spiral computed tomographic study of the genial tubercles for genioglossus advancement.

OBJECTIVE: To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT). STUDY DESIGN AND SETTING: Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods. RESULTS: The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated. CONCLUSION: Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement. SIGNIFICANCE: This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy.     

盐酸二甲双胍治疗Ⅱ型糖尿病疗效评价

为比较盐酸二甲双胍和糖适平对Ⅱ型糖尿病的治疗效果，通过３３例Ⅱ型糖尿病患者服用二甲双胍和３５例Ⅱ型糖尿病患者服用糖适平，观察４ｍｏ后发现二甲双胍在降低血糖、２４ｈ尿糖定量，降低血脂及逆转外周神经病变方面有显著疗效。但二甲双胍不能升高血浆Ｃ—肽水平，不能降低２４ｈ尿蛋白质定量。如能将二甲双胍和糖适平联合应用将会提高疗效，减轻副作用。

Rapid identification of low level hepatitis B-related viral genome in serum.

A sensitive and specific method has been developed to detect hepatitis B virus (HBV) in serum. The method involves two steps: the capture of viral genome from serum using a high affinity IgM monoclonal antibody directed against a common a domain epitope found on the envelope, and the amplification of viral DNA by the polymerase chain reaction (PCR). The amplification is initiated using "generic" primers derived from the core and pre-core sequences which are highly conserved amongst the hepadnaviruses. This rapid technique detects less than 10 infectious virions and may be useful in the study of individuals with acute and chronic liver disease of unknown etiology.
