ABSTRACT
【Objective】 To investigate the effect of isoliquiritigenin on inflammatory response of vascular endothelial cells and whether the regulatory effect of isoliquiritigenin on inflammation is mediated by histone deacetylase 3 (HDAC3). 【Methods】 Human umbilical vein endothelial cells (HUVECs) were cultured in vitro and treated with LPS, different concentrations of isoliquiritigenin and HDAC3 specific inhibitor, respectively. Real-time PCR and Western blotting were used to detect the mRNA and protein expressions of inflammatory cytokines and HDAC3. Male C57BL/6J mice were randomly divided into vehicle group and isoliquiritigenin treatment group. The vascular inflammation model of C57BL/6J mice was established by ligation of the left carotid arteries. The mRNA expressions of inflammatory cytokines and HDAC3 in the carotid arteries of mice were detected by Real-time PCR. A molecular docking study was performed to investigate the interaction between isoliquiritigenin and HDAC3. 【Results】 Compared with the vehicle group, isoliquiritigenin reduced the mRNA expressions of inflammatory cytokines NLRP3, IL-1β, IL-18, MCP-1 and ICAM-1 and decreased the expression of HDAC3 mRNA and protein in HUVECs stimulated with LPS. In addition, isoliquiritigenin also decreased the mRNA expressions of NLRP3, IL-1β and HDAC3 in carotid arteries of ligated C57BL/6J mice. The docking of isoliquiritigenin in the active site of HDAC3 showed that isoliquiritigenin might act through HDAC3. Furthermore, HDAC3 specific inhibitor RGFP966 further promoted the inhibitory effect of isoliquiritigenin on the expression of inflammatory cytokines in vascular endothelial cells. 【Conclusion】 These results suggest that isoliquiritigenin suppresses the inflammatory response of vascular endothelial cells via HDAC3.
ABSTRACT
Objective To research of Huangong decoction combined with routine treatment of western medicine for the postpartum hemorrhage and fundus reduced height of the postpartum hemorrhage (PPH). Methods A total of 242 patients with postpartum hemorrhage were enrolled and divided into two group by random number table: the treatment group (121 patients) and the control group (121 patients). Patients in the control group were treated with the western medicine routine treatment, while the treatment group were treated with Huangong decoction plus routine treatment. Both groups were treated for 3 days with a follow-up of 42 d. The postpartum haemorrhage amount, fundus height reduction were compared. The clinical effect rate was evaluated with postpartum haemorrhage amount, palace at the uterine bottom of the height reduction. Results The total clinical effectiveness rate of the treatment group was 97.5% (118/121), and the control group was 90.1%(109/121). The difference of two groups was statistically significant (χ2=4.478, P=0.034). After production, the uterine bottom height reduction at the first day (9.3 ± 1.4 mm vs. 8.0 ± 1.3 mm, t=7.501), the second day (10.2 ± 1.2 mm vs. 9.1 ± 1.1 mm, t=7.447) and the third day (12.2 ± 1.5 mm vs. 10.1±1.4 mm, t=11.283) in the treatment group were significantly greater than the control group (P<0.01). The postpartum hemorrhage at the first day (732.1 ± 84.3 ml vs. 766.4 ± 90.0 ml, t=-3.066), the second day (480.1 ± 62.0 ml vs. 590.0 ± 74.3 ml, t=-12.513) and the third day (240.4 ± 36.3 ml vs. 340.3 ± 52.0 ml, t=-17.351) in the treatment group were significantly less than the control group (P<0.01). After postpartumt, the uterine volume (632.1 ± 101.2 mm3 vs. 701.4 ± 135.7 mm3, t=-5.095) at third day and (142.3 ± 16.5 mm3 vs. 160.6 ± 19.7 mm3, t=-7847) at the follow-up, in the treatment group were significantly less than the control group (P<0.01). Conclusions The Huangong decoction combined with routine treatment of western medicine can improve the clinical symptoms in patients with PPH, and contribute to the recovery of disease.
ABSTRACT
Data mining technology is called into play to comb and excavate data in the hospital information system(HIS)for the purposes of hospital management and patient safety.Data tables in the electronic medical record system were effectively remodeled as necessary.These measures help build a medical quality surveillance system which is based on the electronic medical record system,with such functions as real-time monitoring and pre-warning.The control framework consists the critical cases control system,surgery and invasive operation control system,overall control system,and TCM strengths application control system.
ABSTRACT
Purpose:It has been shown that the heart is a chaotic oscillator. So it is appropriiate to use the Lyapunov exponent, an important parameter to identify the nature of non-linear dynamical systems, for identifying the state of human heart. Methods:Preliminary results are obtained in this paper using Wolf's algorithm for 8 normal and 107 abnormal ECG recordings. Results:Significant differences are found between the Lyapunov exponents of normal ECG and ECG with obvious coronary stenosis (OCS), but there is no significant difference between the Lyapunov exponents of normal ECG and ECG with mild coronary stenosis (MCS);Significant differences are also found between the Lyapunov exponents of R-R interval series of normal ECG、ECG with MCS and ECG with OCS. Conclusions:It is apparent that the R-R interval series can give us more messages about human heart, and the Lyapunov exponents of ECG and R-R interval series are the appropriate parameters for the identification of the physiological states of human heart. It is possible to use Lyapunov exponent for early diagnosis of Coronary Heart Disease.
