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 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.

Objective: To determine ? asarone and ? asarone in Rhizoma acori tatarinowii(RAT) . Methods: HPLC condition consists of ODS C 18 column(150mm?4.6mm, 5?m), methanol: water(6∶4) as mobile phase containing potassium dihydrogen phosphate 1.4g and sodium lauryl sulfate 1.2g per 1000mL, detective wavelength at 257nm, flow rate at 1.0mL?min -1 . Results: For RAT the mean recovery of 99.02%( RSD =1.03%) for ? asarone, 101.26%( RSD =3.57%) for ? asarone are obtained, respectively. Conclusion: The method is sensitive, rapid and accurate.

[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 determine the component of naphtha from Acorus tatarinowii Schott.which can pass through the blood-brain barrier. Methods: Naphtha in rat brain was analyzed by GC-MS after gastric infusion of naphtha. Results: The methylisoeugenol,elemicin, ?-asarone and ?-asarone were detected in rat brain. Conclusion: The resuscitative effect of naphtha is resulted from the comprehensive action of multiple components.

The progress of objective and digital diagnosis of Traditional Chinese Medicine (TCM) is not optimistic.There is no denying that there are a lot of research ideas and methods,on the other hand,the understanding of TCM is very one-sided,fuzzy and even wrong.This paper attempts to absorb the quintessence of TCM in clinical medical information detection and treatment ideas from the measurement science and modem information detection and processing point of view.Ideas and means of clinical medical information detection and treatment in TCM not only coincide with,but also improve that of modem information detection and processing way and means,which have high reference value.The way of thinking and means,not only for medical information detection and processing,but also provide a valuable reference for other areas of information detection and processing.

Objective To investigate the risk factors for postoperative nausea and vomiting (PONV) in spinal anesthesia patients.Methods A total of 841 patients received spinal anesthesia were visited after operation.Data were analyzed using univariate analysis and multivariate Logistic regression to identify risk factors related to PONV.Results PONV occurred in 94 patients (11.2%,94/841).Univariate analysis showed that PONV was unrelated with gender,age,ASA classification,anesthesia mode (P > 0.05),related with operation department (P =0.026),body mass index (P =0.020),education level (P =0.000),history of previous surgery anesthesia (P =0.005),history of PONV (P =0.000),history of kinesia (P =0.002),smoke (P =0.019),intraoperative using of tramadol (P =0.018).Multivariate analysis showed that operation department (OR =4.039,95% CI 1.331-12.259,P=0.048),education level (OR =3.504,95% CI 1486-8.260,P=0.015),history of PONV (OR =5.113,95% CI 1.790-14.606,P =0.002),intraoperative using of tramadol (OR =5.316,95% CI 1.091-25.908,P =0.039) were identified as independent risk factors for PONV.Conclusions The independent factors associated with PONV following spinal anesthesia include operation department,education level,history of PONV,intraoperative using of tramadol.Identifying patients who are at high risk for PONV will enable the formation of more timely management project.
