Objective To assess myocardial contractility in essential hypertention(EH) of different remoldings by means of circumferential midwall fractional shortening (mFs), relation between mFs and circumferential end-systolic stress(mFs-cEss). Methods The eject fraction(EF), circumferential end-systolic stress(cEss), fractional shortening(Fs), mFs was calculated in 115 EH patients and 29 normal controls. Relations in mFs-cEss, Fs-cEss between the subjects were analysed with linear correlation and linear regression. Results In using EF,Fs,Fs-cEss to assess chamber function of the patients with hypertension of four left ventricular remoldings, it shows apart from eccentric hypertrophy, the rest three remoldings were overestimative. MFs assessing myocardial contractility in four remoldings was lower than that of the controls, especially obvious in concentric hypertrophy patients(P

The purpose of this study was to observe whether HBV can infect HSC in vitro. LX-2 cells, the human activated HSC cell line, were incubated with human serum containing HBVDNA at final concen-trations from 0.01 to 10 copies/cell and harvested after 24,48 and 72 hours. Hepatitis B surface antigen (HBsAg) and hepatitis B core antigen(HBcAg) were detected by lmmunohistochemistry dyed by DAB. By Immunohistochemistry, no positive particles in LX-2 cells, a few of dark brown particles (HBsAg and HB-cAg) were found in cytoplasm and nucleoli of HepG2.2. 15 cells,a lot of clark brown particles were found in liver biopsies of patients with chronic hepatitis B. In vitro, there was no evidence that HBV can infect and express antigens in LX-2 cells.

To verify the role of introvascular ultrasound(IVUS) in diagnosis of atherosclerosis. MethodsINUS wasused to measure the position, quality and the thickness of the plaque in the elastic artery and biopsy materials. After using HE andHart stains, a micrometer was used to measuse the thickness of plaques and arterious walls. And electron microscopy was used to ob serve the pathological changs of the plaque. ResultsBy histological observation compared with IVUS, the conformable rate of plaque anmounted to 94%. The plaque could be seen in 12 sites of control group. Among 33 sites, 32 plaques were found pathologic exmination while IVUS showed 30 plaques in the experimental group. The two methods had a gcod correlation on the thick measurement of plaque and the media( r = 0.835, P＜0.05 and r = 0.814, P＜ 0.05). But they had a poor correlation on the measurement of the intirna( r = 0.055). ConclusionsBy pathological examination and the quantitative analysis, IVUS can obtain the common purpose in diagnosing atherosclerosis and measuring the media thickness. But it can not be used in measurement of the intima.
