2.Innovation in scientific researches
Academic Journal of Second Military Medical University 2000;0(10):-
Despite of great strides already made,China is still lagging behind Western countries in terms of scientific innovation,which is not parallel with China's economic achievement. Here I would like to summarize my experience in 30-year science research from the following two aspects:one is the motivation and source of innovation and the other is the value and implication of innovation. I will mainly focus on the relation of innovation with accidental discovery,reversed thought,long term accumulation,and challenge of the authorities. I will also discuss the great role of innovation in developing new theories,guiding medical practice,and dealing with emergencies.
3.Arterial baroreflex function and left ventricular hypertrophy
Academic Journal of Second Military Medical University 2004;25(4):448-448
It is well known that the arterial baroreflex(ABR)plays a key role in the regulation of heart rate and stabilization of blood pressure.Currently,it appears that ABR dysfunction is involved in the pathophysiology of cardiovascular disease states.Since the mid-1990s,a number of studies have been carried out in our laboratory to explore the pathological significance of ABR function in cardiovascular damage.This minireview summarizes our research work on the topic of ABR and left ventricular hypertrophy(LVH).On the basis of discussion concerning the importance of ABR dysfunction in hypertensive LVH and sinoaortic denervation-induced LVH,we advance a new strategy for reversal of LVH,that is,restoration of impaired ABR function.We tested this hypothesis in animal models with ABR deficiency.It was found that improvement of impaird ABR function with long-term treatment of ketanserin or candesartan was accompanied by reversal of LVH.The preliminary results indicate that it is feasible to target ABR for treatment of LVH.

Academic Journal of Second Military Medical University 1999;0(12):-
Objective:The m ain objective was to exam ine the role of haemodynamics in rat aortic and left ventricular hy- pertrophy produced by sinoaortic denervation(SAD) .Methods:Rats were examined at different times after SAD or sham op- eration(Sham) .Haem odynamics were recorded continuously in conscious unrestrained rats.The time course of haemodynam ic changes and cardiovascular hypertrophy was observed and linear regression analysis was performed to study the role of haemodynam ics in SAD- induced aortic and left ventricular hypertrophy.L ong- term mortality,water and food intake,and body weight were also determ ined after operation.Results:High mortality(40 % ) ,dram atic reduction of water and food intake,and weight loss occurred within1week after SAD.Chronic SAD rats exhibited a marked increase in blood pressure variability (BPV) ,with no change in the average level of blood pressure(BP) ,as compared with the Sham control rats.Increased BPV was higher at2 weeks(about threefold) than16 weeks(about twofold) after SAD.Aortic hypertrophy existed in all3kinds of exam ined rats:2 - ,10 - and16 - week SAD rats.L eft ventricular hypertrophy was found only in10 - and16 - week SAD rats. Both aortic hypertrophy and left ventricular hypertrophy were significantly and positively correlated with BPV,but not with BP level.Conclusion:Persistent high BPV following SAD can lead to aortic and left ventricular hypertrophy.The aorta is more sensitive to increased BPV than the heart
5.Role of K_(ATP) on the reduction of blood pressure variability caused by adenosine in sinoaortic denervated rats
Academic Journal of Second Military Medical University 2000;0(10):-
Objective: To determine the effect of K ATP on the reduction of blood pressure variability (BPV) caused by adenosine in conscious, freely moving sinoaortic denervated (SAD) rats. Methods: Using computerized analytic system of blood pressure (BP), five groups treated with adenosine, adenosine A 1 receptor agonist N 6 cyclopentyladenosine (CPA), A 2 receptor agonist 5′ N cyclopropyl carboxamido adenosine (CPCA), ATP sensitive K + channel (K ATP ) blocker glibenclamide, and CPCA with the K ATP blocked by glibenclamide in advance were used. BP, heart period (HP) and BPV were analyzed. Results: Both adenosine and CPCA significantly decreased BPV in SAD rats, but CPA had no influence on it. Glibenclamide markedly reduced BPV in SAD rats as well, furthermore, it might antagonize the effect of CPCA on BPV by blocking K ATP . Conclusion: K ATP plays an important role in the development of high BPV in SAD rats. [
6.Circadian variation in cardiovascular events and strategies of therapy
Chinese Pharmacological Bulletin 1986;0(05):-
Many studies, both retrospective and prospective, have shown that there is a circadian variation in acute cardiovascular events with a peak during the morning and a trough during the night since the mid 1980s. In addition to the morning peak, a secondary less prominent peak has been observed in the late afternoon in many studies. This circadian variation may well be at least partly linked to the known physiological circadian rhythms. Because the duration of the therapeutic effect of many drugs taken at the conventional time will have reached subtherapeutic levels at the time of waking and commencing activity the following morning, timing of medication is discussed to improve the protection of the patients with cardiovascular disease in the morning waking hours.

AIM: To study apoptosis and related genes expressions of cardiomyocytes in sinoaortic-denervated(SAD) rats. METHODS: SAD or sham-operation (Sham) was performed in male SD rats at the age of 10 weeks. After 16 weeks, apoptotic cells were stained in situ by terminal dexynucleotidyl-transferase mediated-dUTP nick end labeling (TUNEL). All stained results were analysised using computer image analysis techniques. Protein products and mRNA of Bcl-2, Bax, Fas and Fas-L were assessed by quantitative immunohistochemistry and RT-PCR. RESULTS: The numbers of apoptotic cardiomyocytes were significantly increased in SAD rats, the expressions of Bcl-2 were significantly decreased, whereas Bax,Fas and Fas-L were significantly increased in SAD rats. THZ]CONCLUSIONCONCLUSION: Apoptosis and dysregulation of gene expressions may be involved in the cardiomyocytes remodeling in SAD rats.

The contents of ir-arg-vasopressin (ir-AVP) and ir-?-endorphin (ir-?-EP) in plasma, anterior pituitary (AP), posterior pituitary (PP), oblongata (OB) and hypothalamus (HP) were measured by radioimmunoassay after sinoaortic denervation (SAD) in rats. It was showed that the ir-AVP contents in OB and ir-?-EP contents in AP, PP and OB were significantly elevated 1 d after (SAD) (P

Using computerized analysis of hemodynamics in conscious unrestrained rats, we tested the effects of intracerebroventricular administration of ketanserin (50 ?g), a special 5-HT2 antagonist, on blood pressure (BP), blood pressure variability (BPV), baroreflex-blood pressure control (ABR-BP), and baroreflex-heart period control (ABR-HP). The result are as follows: (1) There was no significant depression of blood pressure after intracerebroventricular administration of ketanserin; (2) Ketanserin could significantly decreased BPV, and enhanced ABR-BP and ABR-HP; (3) The decreasing of BPV was associated with enhancement of ABR-BP, but these changes were no related to the level of BP, indicating that the hypotension induced by ketanserin was not related to the enhancement of ABR-BP; (4) There was no significant negative relationship between ABR-BP and BPV after intracerebroventricular administration of ketanserin.

Objective:To investigate the correlation between arterial baroreceptor reflex (ABR) function and target organ dam age (TOD) in spontaneously hypertensive rats (SHR) .Methods:Twenty- four- hour blood pressure (SBP and DBP ) ,blood pressure variability (BPV ) ,heart rate (HR ) and HR variability (HRV ) were m easured in conscious, unrestrained SHR and Wistar- Kyoto (WKY ) rats.ABR function control of heart period (ABR- HP) and blood pressure (ABR- BP) were determined respectively.Hypertensive TOD was evaluated according to the scoring system.Results:SBP, DBP and their BPV were significantly increased in SHR compared with those of WKY rats.No difference of HR was found between the 2 strains,but HRV was significantly decreased in SHR when com pared with WKY rats.ABR- HP and ABR- BP of SHR were significantly decreased compared with those of WKY rats (P
