OBJECTIVE To investigate the influence of tea polyphenol in alcoholic liver(hurted) rat by observing its blood plasma endotoxin level,and to provide the direction of new(treatments) and means for the prevention of alcoholic liver disease.METHODS Thirty S-D rats(15 female,15 male) were divided into five groups randomly(noted as A,B,C,D,and E,with equal male and female),and fed in the cleanliness class laboratory.Excepting group E which was given saline,all other groups were given alcohol(56% Hongxing spirits) with the dosage of 7 g/kg once everyday.At the same time,rats in groups B,C and D were given tea polyphenol with the dosage of 0.05,0.125,0.25 g/kg.In the end of the fourth week,got the rats vein blood to determinae serum ALT,AST level and blood plasma endotoxin level.RESULTS The serum AST of the group A was higher than other 4 groups;the blood plasma endotoxin level in groups B,C,and D were(consequently) lower than in group A.CONCLUSIONS The tea polyphenol could reduce the blood plasma endotoxin level in alcoholic liver hurted rat.Its possible mechanism is to repress the isotopy of bowel flora,and to maintain the normal function of bowel mucous membrane.This research provides a new way for curing the alcohol liver hurt.

Objective To explore the distribution of pathogens in lower respiratory tract infection, and to explore the drug resistance, and summarize the clinical experience.MethodsFrom February 2014 to August 2016 in Changxing county people's hospital, the specimens of the patients with lower respiratory tract infection were analyzed.Distribution of pathogenic bacteria was analyzed and its drug resistance was summarized.ResultsA total of 100 strains of bacteria were isolated, including 27(27%) strains of fungi, 26(26%) strains of gram positive bacteria, 47(47%) strains of gram negative bacteria.The proportion of gram negative bacteria was significantly higher than that of gram positive bacteria and fungi, and the difference was statistically significant (P<0.05).Different pathogenic bacteria have different drug resistance to commonly used antibiotics.The resistance of Candida albicans to fluconazole was 100.0%, the resistance of Staphylococcus aureus to compound sulfamethoxazole was 90% and to gentamicin was 100.0%, the resistance of Escherichia coli to levofloxacin was 100.0%.ConclusionGram negative bacteria accounted for the highest proportion in pathogen of lower respiratory tract infection.Different pathogenic bacteria have different resistance to different antibiotics in clinical, and monitoring and rational use of drugs should be strengthened in order to improve the efficacy and reduce drug resistance.

Objective By quantitative tissue velocity i maging(QTVI),to observe longitudinal wall motion characteristics during isovolumic contraction, ejection, isovolumic relaxation, early relaxation, atrial systole phases in regional myocardium of myocardial infarction patients with three diseased blood vessels, and to assess postsystolic shortening in isovolumic relaxation phase and its clinical meanings. Methods Left ventricular regional myocardium of 30 myocardial infarction patients (MI group) and 30 non-cardiac disease subjects (control group) was assessed by QTVI. After dynamic images were collected and information was analyzed off-line, left ventricular myocardial velocity and time velocity integral profiles were acquired along long axis asynchronously in basal and middle segments of different walls, peak velocities (V IC , V S, V IR , V E, V A) during different phases and maximum time velocity integral (TVI max )in regional myocardium was measured. Results Peak velocities(V IC , V S, V IR , V E, V A) in different segments of left ventricular regional myocardium in MI group were lower than those of control group, especially more obviously in infarcted segments. Peak velocity amplitude in ejection declined, but it had positive velocity spike; abnormal positive velocity in isovolumic relaxation phase suggested postsystolic shortening. What's more, time velocity integrals in some segments of MI group had two wave crests, reached maximum in isovolumic relaxation phase, but were still lower than that of control group. Conclusions Systolic and diastolic function in MI patients with three diseased blood vessels are apparently impaired; abnormal movement in isovolumic relaxation phase suggests existence of postsystolic shortening and abnormal wall motion in regional myocardium.V IR is a marker of abnormal regional wall motion and ischemic myocardium.

Objective To measure various parameters with tissue Doppler imaging, quantitatively score left ventricular wall motion, assess longitudinal wall motion in total and regional myocardium of myocardial infarction patients. Methods Tissue tracking was adopted for assessing left ventricular regional myocardium of 30 myocardial infarction patients (MI group) and 30 normal subjects (control group). After collecting dynamic images and analyzing information off-line, maximum displacement along long axis asynchronously in annular, basal, mid and apical segments of different walls were acquired, and left ventricular wall motion score indexes(TT score indexes) were calculated. Results Maximum displacement in different segments of left ventricular regional myocardium was lower in MI group than control group, especially in infarcted segments. TT score indexes were lower in MI group than control group( 6.23? 1.93 vs 9.71? 1.08, P

Objective To observe longitudinal motion characteristics of regional myocardium in left bundle branch block(LBBB) patients. Methods Left ventricular regional myocardium of 15 LBBB patients and 15 normal subjects were assessed by tissue Doppler imaging(TDI). Peak velocities(V_S,V_E,V_A) during isovolumic contraction, ejection, isovolumic relaxation, early relaxation, atrial systole phases and maximum time velocity integral(TVI_(max)), displacement(D_(max)) in mitral(tricuspidal) annulets of different walls were measured. Furthermore, the different parameters from the beginning of electrocardiogram QRS wave to the beginning of S wave(Q-Sb),to the tip of S wave(TTP), the acceleration time of IVC wave(IVA), the acceleration time of the E wave(Eac),the durations of different phases(IVC,S,IVR,D)and IVC/S and others were acquired. Results Peak velocities(V_S,V_E)and TVI_(max) in left ventricular septal, inferior, anterior, posterior walls were lower in LBBB group than control group; those parameters in different segments of left and right ventricular lateral myocardium were not significantly lower in LBBB group than control group. What is more, D_(max) of mitral annular sites in LBBB group were lower than control group. Q-Sb, TTP and IVC in left ventricular septal, inferior, anterior, posterior walls were longer in LBBB group than in control group; IVA lengthened, Eac and Edc shortened in left ventricular septal, inferior walls; IVR lengthened, diastole shortened, IVC/S increased in left ventricular septal, inferior, and posterior walls. Conclusions Abnormal left ventricular activation sequence during LBBB caused obvious impairment in total and regional systolic and diastolic function. And delayed contraction with different degrees were resulted from different walls of left ventricle with intraventricular dyssynchrony; but contraction in right ventricle was not significantly delayed, with interventricular dyssynchrony.
