A design of the wireless ambulatory blood pressure monitoring system has been presented based on ARM embedded microprocessor and GPRS module for the extention of native mobile telemedicine. The whole system framework and flow chart have been introduced in detail. Based on RBF neural networks, the ambulatory blood pressure data curve has been simulated, and the trend curve provides a reliable gist for the prevention, treatment, diagnosis and therapeutic efficacy of cerebrocardiac diseases.

OBJECTIVETo study the relationship between serum testosterone levels and the plaque formation of the carotid artery in a population-based cohort of independently living healthy women above 60 years of age.
METHODSAnalysis of the healthy elders from a population-based cohort study in 9 communities of Beijing. Carotid intima-media thickness and atherosclerotic plaques were determined ultrasonographically. Serum testosterone levels were measured by immunoassay. The data were analyzed with ANOVA and logistic regression analysis.
RESULTSThere was an inverse correlation between testosterone and plaque formation in old females (P < 0.01), while no association was found in males. Female with testosterone levels in the lowest quartile (< 0.49 nmol/L) had more risk of plaque formation (OR = 3.805, P < 0.01) after adjusted with age and other traditional factors of atherosclerosis.
CONCLUSIONTestosterone concentrations are negatively associated with carotid artery atherosclerosis in old women in Beijing, experimental and prospective studies are needed to determine the possible therapeutic role of testosterone in atherosclerosis.

Objective To observe the effects of static pressure on the number of cultured retinal M?ller glial cells(RMGC)and expression of glial fibrillary acidic protein(GFAP)and heat shock protein(HSP)70 by these cells.Design Experimental study. Participants Cultured rat RMGC.Methods Rat RMGCs were cultured and identified according to previous method described by Reichenbach.These cells were treated with different static pressures and divided into 4 groups:A(1.33kPa),B(2.67kPa),C(5.33kPa)and D(10.67 kPa)while the cells without treatment was as control group(NC).The morphologies of RMGC in these groups were observed under inverted phased contrast microscope,the number of RMGC counted with conservative method and the viability were studied with trypan blue staining.The expressions of GFAP and HSP70 in RMGCs were detected with the method of western blot.Main Outcome Measures The morphologies of RMGC,cell number,cell viability.Results There were pressure-dependent changes of RMGC number. The cell number of group C and D was less than that of group NC,A and B(P<0.01).High static pressure resulted directly in the decreased ratio of unstained RMGCs(P<0.01).The ratio of unstained RMGCs in group C and D was less than that in group NC,A and B(P<0.01).Many cells in group C and D were injured and the higher the pressure elevated,the more the degree of injury became.The expressions of GFAP and HSP70 in group NC were less than other pressure treated groups and the expression of GFAP in group C and D was higher than that in group A and B.There was no obvious difference between these pressure treated groups.Conclusions High static pressure could cause the injuries of RMGCs.The increased expression of GFAP and HSP70 in RMGC might be regarded as a sign of retinal injury response to high intraocular pressure.

OBJECTIVETo discuss that pathogenesis evolvement regularity of Chinese miniature swine with phlege-stasis cementation syndrome of coronary heart disease.
METHODEighteen Chinese miniature swine were randomly divided to the normal control group, the model group and the Danlou tablet group, with six swine in each group. Except for the normal control group, all of the other groups were fed with high fat diet for two weeks. The coronary heart disease model with phlegm-stasis cementation syndrome was established by injuring left anterior descending artery with interventional balloons and continuously feeding with high fat diet for eight weeks. The levels of BMI, hemorheological parameters, lipids in serum and inflammatory cytokines were observed at the 0th (before the experiment), 2nd (before operation or drug administration), 6th (four weeks after drug administration) and 10th week (eight weeks after drug administration) of study. The levels of TG and TC in liver and the pathological changes in coronary artery tissues were also observed at the end of study.
RESULTCompared with the normal control group, the model group had showed significant increase in the levels of TC, TG, LDL-C and VLDL-C in serum (P < 0.01) from the second week to the end of the experiment, with notable rise in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1). At the 6th week, the levels of BMI and TG and TNF-alpha in serum significantly increased. At the 10th week, the levels of BMI and hs-CRP, IL-6 and TNF-alpha in serum significantly increased as well, with remarkable increase in coronary stenosis, intimal thickness and the ratio between intimal thickness and media thickness (P < 0.05 and P < 0.01), and significant rise in TC and TG in livers (P < 0.01). Compared with the model group, the Danlou tablet group showed obvious reduction in severity of coronary artery lesion, intimal thickness and lumen stenosis ratio and ratio between intimal thickness and media thickness (P < 0.01), BMI, TC, TG, LDL-C and VLDL-C in serum, TC and TG in liver, as well as hs-CRP, IL-6 and TNF-alpha levels in serum (P < 0.05 and P < 0.01), with notable decline in the whole blood viscosity under the shear rates of 5 s(-1) and 60 s(-1).
CONCLUSIONThe interaction of phlegm, blood stasis and toxin syndromes helps promote the progress and development of AS plaques, which is the key pathogenesis of phlegm-stasis cementation syndrome in coronary heart disease.

Chinese Acupuncture & Moxibustion 2005;25(9):654-656
Pu Xiang-cheng, a famous TCM physician in Sichuan Province, were engaged in medicine for dozens of years, with complete and systematical theory and great academic attainments. He summarized whole course of acupuncture and moxibustion treatment by means of verses with easy to be understood and easy to be read aloud, from examination of acupoints, location of acupoints, needling depth, manipulation, reinforcing and reducing to treatment of diseases in departments of internal medicine, surgery, gynecology and five sense organs, etc., and treatment of fainting during acupuncture. This is valuable medical book in recent time and clinically, it has profound inductive significance for later generations.
