Objective:To study the pharmacological action of Vernonia Cinerea(L) Less. Methods: The bacteriostatic test in vitro and the evaluation of effect of Vernonia Cinerea(L) Less. on the propellent function of small intestine of mice, etc were carried out. Results: Vernonia Cinerea(L) Less. prossesses the inhibition on Bacillus coli with lapactic action in vitro, but has the drug resistance to Bacillus dysenteriae and Bacillus coli It can also improve the propellent function of small intestine nomral mice. Conclusions: Vernonia Cinerea(L) Less. is effective for acute gastroenteritis and indigestion clinically.

AIM: To measure microcirculation function in type 2 diabetic patients and non-diabetic subjects with a new measurement method called capillary recruitment. METHODS: 276 type 2 diabetic patients in Shanghai downtown were enrolled and categorized into several groups, those with diabetes duration

AIM:To study the effect of astragalus polysaccharides(Aps)on cholesterol efflux in THP-1 macrophage-derived foam cells.METHODS:After exposed to Aps at different doses,cholesterol efflux and ABCA1 protein levels in cultured THP-1 macrophage-derived foam cells were determined by a ? counter and flow cytometry,respectively.RESULTS:Aps increased cholesterol efflux in THP-1 macrophage-derived foam cells with dose dependent pattern and resulted in an increase in the expression of ABCA1 protein in THP-1 macrophage-derived foam cells.CONCLUSION:The increase in cholesterol efflux by Aps might be related to the up-regulation of ABCA1.

Objective To evaluate AngioJet in patients treated for acute deep venous thrombosis (DVT) by mechanical aspiration thrombectomy combined with catheter-directed thrombolysis (CDT).Methods A retrospective analysis of 83 acute DVT patients treated by mechanical aspiration thrombectomy combined with CDT from Dec 2014 to Oct 2018 in the Third Hospital of Hebei Medical University was conducted.Results 43 cases (routine group) were treated by mechanical aspiration thrombectomy using a large-caliber catheter combined with CDT,and 40 cases (AngioJet group) were treated by AngioJet aspiration thrombectomy combined with CDT(P ＞ 0.05).Thrombosis was completely dissolved in 28 cases in AngioJet group while in 10 cases in large-caliber catheter group.Venous damage rate was higher (38 cases vs.13 cases) in routine group.Conclusion AngioJet combined with CDT can effectively and safety remove thrombus in the lower extremity deep venous system.

OBJECTIVES: Early detection of asymptomatic diastolic dysfunction is essential to prevent the development of heart failure in hypertensive patients. Current studies suggest that left atrial strain contributes to the evaluation of left ventricular diastolic function, but there are fewer studies on the correlation between left atrial strain and diastolic function in hypertensive patients. In this study, we applied a two-dimensional speckle tracking technique to evaluate the changes in left atrial strain in hypertensive patients, and to investigate the relationship between left atrial strain and left ventricular diastolic function. METHODS: A total of 82 hypertensive patients who were visited the Department of Cardiology at the Third Xiangya Hospital of Central South University from July 2021 to January 2022, were enrolled for this study, and 59 healthy subjects served as a control group. According to the number of left ventricular diastolic function indexes recommended by the 2016 American Society of Echocardiography Diastolic Function Guidelines (mitral annular e´ velocity: Septal e´<7 cm/s, lateral e´<10 cm/s, E/e´ ratio>14, left atrial volume index>34 mL/m², peak tricuspid regurgitation velocity>2.8 m/s), the hypertensive patients were divided into 3 groups: Group Ⅰ (0 index, n=36 ), Group Ⅱ (1 index, n=39), and Group Ⅲ (2 indexes, n=7). Two-dimensional speckle tracking technique was used to measure left atrial reservoir strain (LASr), conduit strain, and contraction strain, and to analyze the correlation between left atrial strain and left ventricular diastolic function in hypertensive patients. RESULTS: The LASr, left atrial conduit strain (LAScd), and LASr/(E/septal e´) of the hypertension group were lower than those of the control group, and E/LASr was higher than that of the control group. There was no significant difference in left atrium volume index between the 2 groups (P>0.05). Compared with Group Ⅰ, LASr, LAScd, and LASr/(E/septal e´) were decreased in Group Ⅱ and Group Ⅲ, LASr/(E/septal e´) was also decreased in Group Ⅲ compared with Group Ⅱ (all P<0.05). Compared with Group Ⅰ, E/LASr was increased in Group Ⅲ. LASr was positively correlated with septal e´, lateral e´, E, and E/A, and negatively correlated with E/septal e´. CONCLUSIONS The changes of left atrial function in patients with early hypertension are earlier than those of left atrial structure. Left atrial strain and its combination with conventional ultrasonographic indices [LASr/(E/septal e´)] of diastolic function are potentially useful in assessing left ventricular diastolic function in hypertensive patients.
