1.The clinical progress of antisense technology in the treatment of cancer
Journal of Medical Postgraduates 2003;0(12):-
According to the base complementation, the principle antisense technology is the sequence specific binding of complementary antisense nucleic acids or their chemical modification to the nucleic acids in cells, resulting in the suppression or prevention of gene translation. For the treatment of cancer, a lot of antisense drugs have been designed, which target the genes involved in the pathogenesis of cancer. And some of them have been in clinical trials. The author reviewed the progress of the clinical trials of these antisense drugs.

[Objective] To analyze the main chemical constituents of decoction and concentrated decoction of Rhizoma Acori Tatarinowii (RAT) by gas chromatography-mass spectrometry (GC-MS). [Methods] RAT was decocted and concentrated in the pottery for two times and then 6 batches of the decoction and its concentrated decoction were analyzed by GC-MS. [Results] Five kinds of components in a higher amount were found in the first and second decoction of RAT, including: ?-asarone, ?-asarone, 2, 3-dihydro-3, 5-dihydroxy-6-methyl-4H-pyran-4-one, 5-hydroxymethylfurfural and acoramone. The contents of volatile components of ?-asarone and ?-asarone were lower while those of water-soluble components higher in the concentrated decoction of RAT. [Conclusion] The therapeutic effect of RAT is the co-action of the multiple components of RAT; the effect is related not only with the volatile components but also with the water-soluble components. Therefore, more attention should be paid to the difference of components in the concentrated decoction, which is generally used in the research of new Chinese herbal medicine, and in the clinically used decoction.

Objective: To screen the extraction process of volatile oil in Supplemented Xanthium Powder.Methods: The main compositions of volatile oil contained by every herb in prescription were followed up by GC MS. Results: The extraction process of volatile oil in Supplemented Xanthium Powder was established, that is, Flos Magnoliae and Cortex Moutan Radicis were powdered, their volatile oils were extracted with Herba Menthae together by the steam distillation; then 13 fold first fraction of distillata and 3 fold redistillation liquid were collected respectively; the volatile oil of Rhizoma Liqustici Chuanxiong was extracted with alcohol. Inasmuch as Fructus Xanthii and Radix Angelicae Dahuricae contained less volatile oil, at the same time, to avoide that Fructus Xanthii produced toxicity by water extraction and coumarinic lactones of Radix Angelicae Dahuricae was destroyed their oils were considered unfit for extraction. Conclusion: GC MS is a useful way for follow up optimization of the extraction process of volatile oil in compound prescription of Chinese medicinal and worthy of popularization.

OBJECTIVETo discuss the relative association of soft tissue tension and cervical physiological curvature chang in patients with scapula muscle fasciitis.
METHODSFrom February 2012 to December 2012,29 patients with scapula muscle fasciitis were investigated. There were 10 males and 19 females with an average age of 27.77 years old (ranged from 22 to 40 years old). Routine AP and lateral cervical X-rays were done in all patients. Cervical lordosis was measured according to Borden's method and the pain point tension was measured by soft tissue tension meter. Finally,perform statistic analysis to bove data.
RESULTSLateral X-rays showed 9 cases were normal cervical lordosis, 18 cases were cervical lordosis decreased, 2 cases were cervical lordosis increased. The regression equation of cerical lordosis changes D(Y) and soft tissue tension displacement D0.5 kg (X) was Y = -15.069 + 3.673X.
CONCLUSIONThere is linear relationship between soft tissue tension and cervical physiological curvature change. With the soft tissue tension increases, the cervical lordosis trend to decrease.
