The administration of diuretics and angiotensin-converting enzyme inhibitor (ACEI) in renal parenchymal disease group, αβ receptor blocking agents and calcium antagonists in kidney-artery disease group, a antagonists in adrenal disease and compound antihyportensive agents in other diseases groups all affected advantage of the ratio. Conclusion Diuretics and ACEI are suitable for hypertension caused by renal parenchymal disease, αβ receptor blocking agents and calcium antagonists are suitable for that caused by kidney artery disease, but a receptor blocking agents are suitable for that caused by adrenal disease.

Currently, Lemology in PLA is facing two challenges: i) the threat of emerging infectious diseases (EID), bioterrorism and biological warfare (BW); ii) professional staffs are concerned over their development while the armed forces are undergoing re-organization. Whereas military lemology meets several opportunities such as: Ⅰ) the discipline occupies\ a\ prominent portion in military medicine; Ⅱ) an outbreak of EID and the threat of bioterrorism are closely related to military medicine; Ⅲ) infectious diseases are still common diseases prevalent in both servicemen and civilians; Ⅳ) the present status of lemological study in PLA is in the leading position in the whole nation; Ⅴ) once there should be another outbreak of SARS epidemic such as occurred in 2003 in Beijing, the most expeditions and effective approach is still to deploy the specialists in PLA organizing a medical team to enter the epidemic area. The development strategy of this discipline in PLA is proposed as follows: i) expanding the scope of the discipline; ii) further the construction of the team; ii) perfecting the system for prevention and treatment of EID. Finally, the presumption for the 21st century of the subject is following suggestions are the contemplation for the development of this discipline in the 21st century: i) further emphasize the study of this discipline is beneficial for both military and civilian; ii) to simplify the scope of the discipline is not against its enhancement; iii) the interchanges and collaboration among different disciplines should be encouraged and strengthened.

This study investigated the reversal effect of isotetrandrine, an isoquinoline alkaloid extracted from Caulis mahoniae, on P-glyeoprotein-mediated multidrug resistance in human breast cancer doxorubicin-resistant (MCF-7/DOX) cells. RT-PCR assay and immunity histochemistry assay were used to determine the expression level of mdrl gene and P-gp in MCF-7/DOX cells to elucidate resistant character of MCF-7/DOX cells. The activity of isotetrandine to enhance doxorubicin cytotoxicity was tested using MTT (3-(4,5-dimethyhhiazol)-2,5-diphenyltetrazolium bromide) assay and was evaluated by the reversal fold (RF) values. Intracellular accumulation of doxorubicin was assessed by the determination of doxorubicin-assoeiated fluorescence intensity. Effect of isotetrandrine on the expression level of P-gp in MCF-7/DOX cells was then determined by immunity histochemistry assay. The ability of isotetrandrine to inhibit P-gp function was evaluated by detecting the accumulation and efflux of rhodamine123 ( Rh123 )with flow cytometry (FCM). Verapamil was employed as a comparative agent in whole experiment. The results indicated that MCF-7/DOX cells had phenotype of MDR and that the positive expression of P-gp MCF-7/DOX cells and reversal fold (RF) was significantly higher than that of verapamil (P < 0.05 ), butit hardly affected cytotoxicity of DOX in MCF-7 cells and the expression level of P-gp in MCF-7/DOXcells. The ability of isotetrandrine to inhibit P-gp function was reversible, because incubation of MCF-7/DOX cells with isotetrandrine caused a marked increase in uptake and a notable decrease in efflux of Rh123 and a marked increase of intracellular DOX concentrations. In conclusion, isotetrandrine exhibited potent effect on the reversal of P-gp-mediated MDR in vitro, suggesting that it might become a candidate of effective MDR reversing agent in cancer chemotherapy.
