    • The present invention comprises a novel method of incorporating a tritium label at one or more predetermined sites within an oligonucleotide. In particular, the method comprises contacting a nascent, support-bound oligonucleotide having a free 5' hydroxyl group with a suitable oxidizing agent to oxidize the alcohol to an aldehyde, followed by reducing the aldehyde thereby formed with a suitable tritium-labeled reducing agent such as [ H]NaBH4 to yield the 5' terminal alcohol with a 5' tritium label. Normal automated synthesis can then be continued to yield the oligonucleotide of desired length having the tritium label in the desired location. The oligonucleotides thereby produced have higher specific activity than those previously known in the art. Accordingly, in a second aspect, the present invention provides oligonucleotides having high specific activity. The oligonucleotides of the present invention are useful for determining the pharmacokinetics and biodistribution of their non-radiolabeled counterparts, both in vitro and in vivo.
    • 本发明包括在寡核苷酸内的一个或多个预定位点掺入氚标记的新方法。 特别地,该方法包括将具有游离的5'羟基的新生支持结合的寡核苷酸与合适的氧化剂接触以将醇氧化成醛,然后用适当的氚标记的还原剂形成还原醛, 作为[3 H] NaBH 4,得到具有5'氚标记的5'末端醇。 然后可以继续进行正常的自动化合成,得到所需长度的寡核苷酸,其中所述氚标记位于所需位置。 由此产生的寡核苷酸比本领域已知的寡核苷酸具有更高的比活性。 因此,在第二方面,本发明提供具有高比活性的寡核苷酸。 本发明的寡核苷酸可用于在体外和体内测定其非放射性标记的对应物的药代动力学和生物分布。

    • The motor ventilation structure (20) is disposed inside a housing (31) of the motor (30), and the motor (30) is provided with a drive end (301) and a non-drive end (302) opposite to the drive end. The motor ventilation structure (20) includes: a first air baffle (21), located on the drive end (301), where the first air baffle (21) is spaced from a side wall of the housing of the motor (30), so as to form an accommodation space (210) with the housing (31); a ventilation pipe (22), fixed on the first air baffle (21), where the ventilation pipe (22) extends from the non-drive end (302) of the motor (30) to the drive end (301) of the motor (30) and is in communication with the accommodation space (210); and a double-suction fan (23), fixedly sleeved on a rotation shaft (32) of the motor (30) and disposed on one side, close to the non-drive end (302), of the first air baffle (21), where the double-suction fan (23) is configured to extract air from the non-drive end (302) to the drive end (301), and extract air in the accommodation space (210) and air for axial-radial cooling out of the housing (31) of the motor (30). The motor ventilation structure (20) and the motor (30) may ensure that a bearing of the drive end of the motor (30) has an appropriate temperature, and may achieve relatively high heat dissipation efficiency.

    • Beta-lapachone, which is poorly soluble in most pharmaceutically acceptable solvents, has demonstrated significant antineoplastic activity against human cancer lines. The present invention overcomes this significant limitation by teaching novel pharmaceutical compositions comprising a therapeutically effective amount of Beta-lapachone, or a derivative or analog thereof, and a pharmaceutically acceptable solubilizing carrier molecule, which may be at water-solubilizing carrier molecule such as hydroxypropyl- beta -cyclodextrin, or an oil-based solubilizing carrier molecule, for enhancing the solubility of Beta-lapachone in aqueous solution. The therapeutically effective amount of Beta-lapachone, or a derivative or analog thereof, may be complexed with the pharmaceutically acceptable solubilizing carrier molecule in aqueous solution. The novel pharmaceutical compositions may be administered with a second anticancer agent or in combination with radiation therapy. A formulation of Beta-lapachone or a derivative or analog thereof, complexed with a pharmaceutically acceptable solubilizing carrier molecule, wherein the complex can be freeze-dried and when subsequently reconstituted in aqueous solution is substantially soluble is also disclosed. Emulsions of Beta-Lapachone in a pharmaceutically acceptable fat emulsion vehicle are also provided. Also disclosed are methods for treating cancer by administering to a patient the novel pharmaceutical compositions and formulations. Pharmaceutical kits are also provided.
