The coronary collateral circulation is an alternative source of blood supply to the myocardium jeopardized by failure of the original vessel to provide adequate flow. Angiogenesis growth factors induce angiogenesis to promote collateral circulation, been demonstrated in a number of different animal test and phase Ⅰ clinical experience to induce collateralization in the ischemic area and improve cardiac function. Although there are several unsolved questions, the pharmacologic use of angiogenesis growth factors will represent a viable therapeutic alternative for the patients with ischemic heart disease.

OBJECTIVE:To research the correlation between per capita disposable income,investment of pharmaceutical advertisement,people’s healthy level,pharmaceutical price and the demand of drugs in China METHODS:Based on the economical theory,the methods of the econometrics and the Eviews were adopted to establish the model of demand function RESULTS & CONCLUSION:Under the background of the non-full competition,the improvement of people’s living conditions can lead to the demand of drugs The changes of drug price have little influence on the demand of drugs

Objective To investigate the characteristics of P3a and P3b which are the subcomponents of P300 event-related potential in patients with vascular cognitive impairment (VCI) ,and to investigate the relations between P3a,P3b and the changes of cognitive function and cerebral blood flow. Methods Thirty patients with VCI and twenty two normal subjects were tested for P3a and P3b cognitive function ischemic focus and cerebral blood flow and then analyzed for correlation. Results (1) The latency of P3a ((446 ± 71) ms, (429 ± 67) ms, (446±61)ms,(428±66)ms)and P3b((496 ±73)ms,(478 ±75)ms,(498 ±77)ms,(483 ±77)ms) was significantly prolonged in patients with VCI compared with that in normal subjects in all recorded regions(P<0.01) . The amplitude of P3a in patients with VCI ((3.3 ±2.6)μV,(3.3 ± 1.8)μV) was significantly lower than that in normal subjects in Fz and Pz (P<0.01) ,and the amplitude of P3b in patients with VCI((4.5 ±2.5)μV,(6.4 ± 3.8)μV,(5.3 ±3.8)μV,(5. 3 ±3.0)μV) was significantly lower than that in normal subjects in all recorded regions (P < 0.01 or P<0.05) . (2) The latency of P3a and P3b in patients with VCI was negatively related to the scores of sub items of attention and MMSE total scores (P < 0.05 or P < 0.01), the amplitude of P3a was positively related to the scores of MMSE total scores(P<0.05) ,the amplitude of P3b was positively related to the scores of attention and MMSE total scores(P<0.05). (3) The latency of P3a in patients with VCI was positively related to frontal lobe(P<0.05) ,and the latency of P3b was positively related to parietal lobe(P<0.05). (4) The latency of P3a in patients with VCI was positively related to RILMCA,RILACA and RIRACA(P<0.05 orP<0.01) ,the latency of P3b was positively related to RILMCA,RIRMCA and RIRACA(P<0.05 orP<0.01) ,and the amplitude of P3a was positively related to RILACA(P<0.01). Conclusion P3a and P3b are good objective indexes for testing the descent of cognitive function in patients with VCI,which can provide reference basis for the clinical diagnosis.

Dorsal-ventral axis formation is one of the earliest and the most important steps of patterning formation during early embryogenesis.The molecular basis of dorsoventral axis formation reflects the fundamental issues of orchestrated cell proliferation and differentiation.Wildly speculated since the Renaissance,the effort of deciphering the mechanisms of dorsal-ventral axis formation has contributed significantly to our current understanding of disease pathogenesis.Here,we focused our discussion on the recent discovery of the convergence of dorsal and ventral signaling pathways during early embryogenesis and its implications in cancer biology and beyond.

Objective To study on the correlation of hepatic fibrosis with angiotensin Ⅱ (Ang Ⅱ ) in the hepatitis B patients . Methods The electrochemical luminescence and the rate method were adopted to detect hyaluronidase (HA) and Ang Ⅱ levels in 92 cases of acute hepatitis B (acute group) ,108 cases of chronic hepatitis B(chronic group) and 50 healthy people(control group) , and the detected results were performed the correlation analysis .Results Compared with the acute group and the control group ,the HA and Ang Ⅱ levels in the chronic group were increased significantly (P<0 .05) .The HA and Ang Ⅱ levels had statistical differ-ence between the acute group and the control group (P<0 .05) .Further analysis showed that there was a positive correlation be-tween HA and Ang Ⅱ levels(r=0 .629 ,P<0 .05) .Conclusion There the HA level is closely related with the Ang Ⅱ level ,and both of them participate in the process of liver fibrosis ,their levels have the guiding significance in evaluation of severity of liver fi-brosis in the patients with hepatitis B .

OBJECTIVE:To evaluate the status quo and the developmental trend of the application of antidepressant drugs in our hospital.METHODS:The antidepressant drugs in our hospital during2002～2004were analyzed retrospectively in terms of drug varieties,consumption quantity,consumption sum,DDDs etc.RESULTS:The consumption sum of the antidepressant drugs increased year by year,which stood at667.41,802.47and995.02(RMB:ten thousand yuan),respectively in the3years.CONCLUSION:Fluoxetine dominates the first place in terms of clinical application of antidepressants.Furthermore,the application of new type antidepresants has been on the rise.

AIM: To establish the quality standard of Huoxuejiangu Capsules (Radix Salviae Miltiorrhizae, Radix Paeoniae Rubra, Radix Astragali seu Hedysari, Rhizoma Corydalis, Fructus Psoraleae, etc.). METHODS: Radix Astragali, Rhizoma Corydalis, Radix Paeoniae Rubra, Fructus Psoraleae were identified by TLC. The content of tanshinone Ⅱ A was determined by HPLC. RESULTS: Radix Astragali, Rhizoma Corydalis, Radix Paeoniae Rubra, Fructus Psoraleae could be dtected by TLC. Tanshinone Ⅱ A showed a good linear relationship at the range of 0.106～2.12?g, r =0.9996. The average recovery was 98.6%, and RSD was 1.48%. CONCLUSION: The method established is simple, feasible and reproducible. This study provided a method for quality control of Huoxuejiangu Capsules.
