ABSTRACT

Objective@#To explore the clinical efficacy of Yangxin-Fulv decoction combined with amiodarone hydrochloride in the treatment of dilated cardiomyopathy (DCM) complicated with ventricular arrhythmia (VA).@*Methods@#According to the random table method, 103 DCM patients with VA were divided into the control group (n=51) and the research group (n=52). The patients in the control group were given amiodarone hydrochloride orally on the basis of routine treatment, while the research group was given Yangxin-Fulv decoction on the basis of the control group. The treatment course of two groups was 3 months. The total number of ventricular premature beats, ventricular premature second rhythm, triple rhythm, short-term ventricular tachycardia,left ventricular ejection fraction (LVEF), left ventricular diastolic internal diameter (LVEDD), left ventricular end systolic diameter (LVESV) and left ventricular posterior wall thickness (LVPWT) were recorded by dynamic electrocardiogram analyzer. The Dynamic electrocardiogram was used to monitor QT interphase dispersion (QTd) and calibrate QT interphase dispersion (QTcd) and change of QTc interval. Clinical efficacy was evaluated and adverse reactions were recorded.@*Results@#The total effective rate of the research group was 88.5% while the control group was 62.8%, where the difference between two groups was statistically significant (χ2=6.106, P=0.014). After treatment, the total number of ventricular premature beats, ventricular premature second rhythm, triple rhythm, and short-term ventricular tachycardia in the research group were significantly lower than those in the control group (t=-7.005,-4.760,-16.111,-12.059, P<0.001). After treatment, the LVEF of the research group was significantly higher than that of the control group (t=4.024, P<0.01), while the LVEDD, LVESV and LVPWT of the research group were significantly lower than those of the control group (t=-3.913,-6.623,-5.719, P<0.001). After treatment, the changes of QTc interval (402.08 ± 30.14 ms vs. 421.08 ± 32.19 ms, t=-3.093), QTd (65.25 ± 5.63 ms vs. 72.18 ± 5.92 ms, t=-6.089) and QTcd (72.18 ± 10.56 ms vs. 80.53 ± 12.09 ms, t=-3.735) in the research group were significantly lower than those in the control group (P<0.01). During the treatment period, the incidence of adverse reactions in the control group was 7.8% (4/51) and in the research group was 5.8% (3/52). There was no significant difference in the incidence of adverse reactions between the two groups (χ2=0.175, P=0.676).@*Conclusions@#The Yangxin-Fulv decoction combined with amiodarone hydrochloride can improve the clinical symptoms and clinical efficacy of DCM patients with VA by inhibiting ventricular remodeling and arrhythmia.

ABSTRACT

Fluorescence imaging is a powerful technique for the real-time noninvasive monitoring of protein dynamics. Recently, fluorogen activating proteins (FAPs)/fluorogen probes for protein imaging were developed. Unlike the traditional fluorescent proteins (FPs), FAPs do not fluoresce unless bound to their specific small-molecule fluorogens. When using FAPs/fluorogen probes, a washing step is not required for the removal of free probes from the cells, thus allowing rapid and specific detection of proteins in living cells with high signal-to-noise ratio. Furthermore, with different fluorogens, living cell multi-color proteins labeling system was developed. In this review, we describe about the discovery of FAPs, the design strategy of FAP fluorogens, the application of the FAP technology and the advances of FAP technology in protein labeling systems.

ABSTRACT

OBJECTIVE@#To analyze relevant factors for recurrence of ovarian endometriosis after conservative surgery.
@*METHODS@#A cohort study was performed on 310 patients who had performed conservative surgery for ovarian endometriosis. All patients underwent clinical interview. The relevant factors included: age at surgery, clinical symptom and signs, medical history, gynecologic examination, preoperative gravidity, complication, adenomyosis, American Society for Reproductive Medicine (ASRM) scores, post-operative drug therapy, post-operative gravidity and so on. The logistic regression analysis was performed to determine the predictive factors for recurrence of endometriosis.
@*RESULTS@#The relevant factors by univariate analysis were determined. The history of endometriosis surgery, history of intrauterine operation, tenderness nodule at cal-de-sal, bilateral endometrioma, multilocular cyst, intraoperative ASRM scores, complication of adenomyosis and operation time were the risk factors; whereas pre- and post-operative gravidity, post-operative drug therapy, and age at surgery were the protective factors. Meanwhile, the relevant factors by multivariate analysis were also confirmed. The history of endometriosis surgery, history of intrauterine operation, tenderness nodule at cal-de-sal, bilateral endometrioma, multilocular cyst, and intraoperative ASRM scores were the risk factors; whereas post-operative gravidity, post-operative drug therapy, pre-operative gravidity, and age at surgery were the protective factors.
@*CONCLUSION@#The risk factors for recurrence of ovarian endometriosis are history of endometriosis surgery, history of intrauterine operation, tenderness nodule at cal-de-sal, bilateral endometrioma, multilocular cyst, intraoperative ASRM scores, whereas the protective factors are pre- and post-operative gravidity, post-operative drug therapy and age at surgery.

ABSTRACT

Objective To investigate the effect of targeted interruption of cyclooxygenase-2 (COX-2) gene by small interference RNA (siRNA) on the expression of COX-2, vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9) in eutopic and ectopic endometrial stromal cells (ESC) with endometriosis, and the effect on the content of 6-keto-prostaglandin-F1α (6-keto-PGF1α, metabolites of COX) and the apoptosis of eutopic and ectopic ESC with endometriosis. Methods Ectopic and eutopic ESC from 30 women with endometriosis were isolated and cultured respectively. Then, ESC were classified into three groups: interference group, negative control group and blank control group. ESC in interference group were injected into siRNA transfection complex while ESC in negative control group were injected into negative control transfection complex. ESC from 10 participants without endometriosis were the normal control group. The mRNA and protein expression of COX-2, VEGF, MMP-9 in pre-transfected and post-transfected eutopic and ectopic ESC were detected through real time reverse transcription PCR and western blot. The content of 6-keto-PGF1α was determined by ELISA, the apoptotic cells were detected by flow cytometry. Results After interruption of COX-2 gene, there were no significant difference in the mRNA and protein expression of COX-2, VEGF and MMP-9 between the negative control group and blank control group (P>0.05); the mRNA and protein expression of the three genes in interference group were significantly lower than those in negative control group and blank control group (P0.05);compared with those of negative control group and blank control group, the content of 6-keto-PGF1αin interference group decreased significantly (P0.05). The results from flow cytometry displayed that, there was no significant difference in apoptotic cells between the negative control group and blank control group (P>0.05);compared with those of negative control group and blank control group, more apoptotic cells were detected in interference group and the difference was significant (P<0.01);the apoptotic cells in ectopic ESC were significantly more than that in eutopic ESC (P<0.05); the apoptosis rate in interference group of eutopic and ectopic ESC were (33.76 ± 0.06)%, (47.18 ± 0.12)%. Conclusions Our results suggested the targeted interruption of COX-2 gene by siRNA effectively inhibited the mRNA and protein expression of COX-2, VEGF and MMP-9 in both eutopic ESC and ectopic ESC with endometriosis, greatly increased the apoptotic rate of cells and obviously reduced the content of 6-keto-PGF1αby inhibiting the activity of COX-2. And the changes in ectopic endometrium were more evident than those in eutopic endometrium.
