The hemodynamic effects of deliberated hypotension induced by PGE1 or SNP on 14 dogs anesthetized by ketamine were studied separately.MAP was decreased by 30%~40% after infusing PGE,or SNP Hemodynamic variables were measured before and 15 min 30 min after hypotension and 15 min after the discontinuation of infusion.The results indicated that SVRI, PVRI, MPAP, LVSWI and RVSWI all decreased significantly during PGE1-or SNP-induced hypotension. CVP decreased and HR increased significantly during SNP-induced hypotension, but with no significant change during PGE1-induced hypotension and with SVI. CI. PCWP remained unchanged in these two groups throughout the experiments.

OBJECTIVE:To assess the current situation of pharmacoeconomic evaluation studies in China.METHODS:A total of351papers on pharmacoeconomic evaluation,published in Chinese academic journals,issued before year2003,were systematically reviewed.RESULTS:It was improper and nonstandard that Chinese researcher handled the theories,methodologies and analysis techniques of pharmacoeconomic evaluation.CONCLUSION:Further academic communication and the initiative and formulation of the guidelines for pharmacoeconomic evaluation will be necessary to improve the research quality and clinically rational use of pharmaceuticals and serve the formulation of related policies.

Objective To observe the expressions of transforming growth factor-?1(TGF-?1) and plasminogen activator inhibitor-1(PAI-1) mRNA in tubulointerstitial fibrosis( TIF ) rats,and explore the effects of TGF-?1 and PAI-1 on TIF and the interaction between TGF-?1 and PAI-1.Methods Sixty male SD rats were randomly divided into sham operation group (SOR group,n=30) and unilateral urethral obstruction group(UUO group,n=30).TIF model was established via UUO.At d 7,d 14,d 21 after operation,10 rats of every group were killed to obtain renal samples.Histological changes were observed in tubulointerstitium injury under microscope;mRNA and proteins of TGF-?1 and PAI-1 were detected by real-time PCR assays and Western blotting respectively at d 7,d 14,d 21 after experiment onset.SPSS 10.0 software was used to analyze data.Results 1.HE,Masson staining of renal tissues of all groups indicated that there were no fibrosis in SOR rats,there were vacuole degeneration in tubular epithelial cells and inflammatory cell infiltration in tubulointerstitial in UUO rats at d 7,fibrosis aggravated gradually and became severe fibrosis at d 21.2.The expression locations of TGF-?1 and PAI-1 were renal sites of fibrosis by immunohistochemical staining.The mRNA and proteins of TGF-?1 in rats from SOR groups were lower than those of UUO groups at d 7,d 14,d 21(P

OBJECTIVE:To provide scientific basis for the research quality of pharmacoeconomic on the domestic digestive system diseases.METHODS:The pharmacoeconomic research literatures published on professional academic magazines before2003were collected either by computer or by manual research,and which were then systematically evaluated.RESULTS:Some problems were found in the88pharmacoeconomic research literatures obtained,including the study perspective,design,result analysis and discussion of study.CONCLUSION:It is suggested a guideline for pharmacoeconomic research be made and the pharmacoeconomic research be further standardized,the academic exchanges and evaluation feedbacks be increased;meanwhile,personnel training should be emphasized for a better formulation of the related policies and the rational medication in the clinic.

The academic thoughts of Lingnan acupuncture and moxibustion have been an essential part of Lingnan medicine. By exploration and arrangement of Lingnan medicine and books, journals and literatures regarding acupuncture and moxibustion, the ancient and modern acupuncturists and their academic contributions in Lingnan area were reviewed. As a result, the number of Lingnan acupuncturists and their works was low before Qing Dynasty, while from the Republic of China era to People's Republic of China, a considerable amount of acupuncturists emerged with quite a lot of works. By exploration and arrangement of Lingnan acupuncturists and their works and academic opinion, the acupuncture-moxibustion school characterized by Lingnan could be formed and developed.
