Objective:Endometriosis is a common gynecologic disease that frequently leading to chronic pelvic pain,severe dysmenorrhea,and subfertility.As first-line hormonal treatment can interfere with ovulation and may cause recurrent pelvic pain,exploration of new non-hormonal therapeutic approaches becomes increasingly necessary.This review aimed to evaluate the pre-clinical and clinical efficacy and safety of non-hormonal treatment for endometriosisData sources:Databases including PubMed,Embase,Cochrane Library,SINOMED,ClinicalTrials.gov,and Google Scholar were searched up to October 2019,using search terms "endometriosis" and "non-hormonal therapy."Study selection:Twenty-four articles were reviewed for analysis,including nine animal studies and 15 human trials;all were published in English.Results:Twenty-four articles were identified,including 15 human trials with 861 patients and nine animal studies.Some agents have been evaluated clinically with significant efficacy in endometriosis-related pelvic pain and subfertility,such as rofecoxib,etanercept,pentoxifylline,N-palmitoylethanolamine,resveratrol,everolimus,cabergoline (Cb2),and simvastatin.Other drugs with similar pharmacological properties,like parecoxib,celecoxib,endostatin,rapamycin,quinagolide,and atorvastatin,have only been tested in animal studies.Conclusions:Clinical data about most of the non-hormonal agents are not sufficient to support them as options for replacement therapy for endometriosis.In spite of this,a few drugs like pentoxifylline showed strong potential for real clinical application.

Objectives: To analyze the variations of demography, risk factors and triggering factors in acute myocardial infarction (AMI) patients in Beijing area over recent 40 years from 1970s to 2010s. Methods: Our research included in 2 groups: 1970s group, 1314 patients from Beijing collaborative group of coronary artery disease prevention and treatment from 1972-01 to 1973-12; 2010s group, 2200 patients from China AMI registry in Beijing area from 2013-01-01 to 2014-09-30. Demographic characteristics including gender, age, farmer proportion, risk factors and triggering factors for AMI occurrence were compared between 2 groups. Results: Compared with 1970s group, 2010s group had more patients>70 years of age (15.8% vs 25.6%, P<0.001), more with male gender (68.3% vs 75.6%, P<0.001) and the higher farmer proportion (6.5% vs 14.5%, P<0.001); 2010s group showed more patients with previous histories of stroke (6.2% vs 10.5%), MI (9.5% vs 11.9%) and diabetes mellitus (DM) (6.2% vs 27.6%), all P<0.05; 2010s group presented that less patients were triggered by mental stress (51.1% vs 15.2%, P<0.001), while more were induced by physical stress (40.0% vs 61.1%, P=0.007). Conclusions: There were significant changes in recent 40 years for AMI patients in terms of age, gender, farmer proportion, previous histories of stroke, MI and DM; it appeared as aging, androphany and ruralized trends. Physical stress and unhealthy lifestyle were the major triggering factors for AMI occurrence nowadays, more specific efforts should be conducted for heart disease prevention and education.

Objective To investigate the impact of the regional cooperative chest pain center (CPC) on therapeutic time and short term outcome after primary percutaneous coronary intervention (PCI) of patients with ST segment elevated myocardial infarction.Methods 372 patients with ST segment elevated myocardial infarction were enrolled in the study who had received were operated primary PCI 18 months before and after the regional cooperative CPC was set up.There were 156 patients in the green channel group before the setup of CPC and 216 patients in the CPC group.Total ischemia time,first medical contact (FMC) time,FML-to-balloon (FMC2B) time,door-to-balloon (D2B) time,hospital mortality rates,cardiac failure rates on the next day after PCI,length of CCU stays and hospital stays were compared between the two groups.Results Compared to the green channel group,total ischemia time[(281.0±102.7)min vs.(365.2±115.6)min,P＜0.05],FMC time [(174.3±97.5) min vs.(225.4±104.6) min,P＜0.05],FMC2B time [(106.7±61.2) min vs.(139.8±75.7) min,P＜0.05] and D2B time [(75.2±45.4) min vs.(102.4±53.7) min,P＜0.05] of the CPC group were significant shorter.The rates of reaching the standard of FMC2B time (70.83％ vs.34.62％,P＜0.001) and D2B time (75.93％ vs.40.38％,P＜0.001)were significantly higher in the CPC group.Cardiac failure rates on the next day after PCI was lower in the CPC group (14.35％ vs.23.72％,P=0.021),and CCU stays was shorter [(64.3±13.72)h vs.(92.6±15.65)h,P=0.043].Conclusions Establishment of a standardized regional cooperative CPC requires combination and consideration of the characteristics of local resources FMC2B time and D2B time of STEMI patients can be shorten by a standardized CPC lending to further shortening of total ischemia time and improvement in cardiac function.

BACKGROUNDVentricular septal rupture (VSR) remains an infrequent but devastating complication of acute myocardial infarction (AMI). The best time to undergo surgical repair is controversial and there is currently no risk stratification for patients with VSR to guide treatment. The purpose of this study was to review the clinical outcomes of 70 patients with VSR, to analyze the short-term prognosis factors of VSR following AMI, and to make a risk stratification for patients with VSR.

METHODSA total of 70 consecutive VSR patients following AMI treated in our hospital from January 2002 to October 2010 were enrolled in this study retrospectively. The difference of clinical characteristics were observed between patients with VSR who survived ≤30 days and survived >30 days. We analyzed the short-term prognosis factors of VSR and established the short-term prognosis index of VSR (SPIV) based on the Logistic regression analysis to stratify patients with VSR.

RESULTSAmong 12 354 patients with acute ST-segment elevation myocardial infarction, 70 (0.57%) patients (33 males and 37 females) were found to have VSR. The average age was (68.1±8.5) years. Fifty-four (77.1%) patients were diagnosed with an acute anterior infarction. Patients with VSR selected for surgical repair had better outcomes than patients treated conservatively; 1-year mortality 9.5% versus 87.8%, P < 0.005. Logistic regression analysis revealed that female (P = 0.013), anterior AMI (P = 0.023), non-ventricular aneurysm (P = 0.023), non-diabetes (P = 0.009), Killip class 3 or 4 (P = 0.022) and time from AMI to VSR less than 4 days (P = 0.027) were independent risk determinants for shortterm mortality. SPIV ≥9 indicates a high risk as the 30-day mortality is 77.4%; SPIV <8 indicates a low risk as the 30-day mortality is 28.6%; SPIV between 8 and 9 indicates a moderate risk.

CONCLUSIONSVSR remains a rare but devastating complication of AMI. The independent risk determinants for short-term mortality of VSR were female gender, anterior AMI, non-ventricular aneurysm, non-diabetes, Killip class 3 or 4, and the time from AMI to VSR less than 4 days. It is reasonable to take more active treatments for the patients at high risk to save more lives.

Objective To investigate the impact of cytochrome P450 (CYP) 2C19 681G>A polymorphism on long-term prognosis of clopidogrel-treated Chinese patients after percutaneous coronary intervention (PCI).Methods Between January 1, 2009 and August 31,2009, 267 patients with coronary heart disease who received PCI and treated with clopidogrel for 12 months were enrolled. CYP2C19*2 was detected by MALDI-TOF MS and patients were grouped into CYP2C19*1/*1(n=130) and CYP2C19*2 carriers group (n=137). Follow-up was 12 months. The primary endpoint was angina recurrence, urgent coronary revascularization, acute myocardial infarction, stent thrombosis, death and the combined end points. Results Baseline data were similar between two groups (P>0.05).Urgent coronary revascularization and the combined end points occurred more frequently in CYP2C19*2 carriers than in CYP2C19*1/*1 patients (7.3% vs. 1.5% and 8.0% vs. 2.3% respectively,all P<0.05). But incidence of angina recurrence, acute myocardial infarction, stent thrombosis and death was similar between two groups (all P>0.05).Hazard risk of 1 year cumulative survival of CYP2C19*2 carriers group was significantly higher than CYP2C19*1/*1 group after PCI (HR=3.59, 95%CI: 1.02-12.87, P<0.05). Conclusion CYP2C19 681G>A polymorphism is a determinant of prognosis in coronary heart disease patients receiving chronic clopidogrel treatment after PCI.

BACKGROUNDSpontaneous attack of variant angina (VA) is a unique component of coronary artery disease (CAD), and associated with severe cardiac events. However, no data are available regarding sex differences in Chinese patients with spontaneous attacks of VA. Accordingly, the present retrospective study was initiated to evaluate the Clinical characteristics of Chinese female patients with spontaneous attacks of VA.

METHODSFrom January 2003 to January 2008, a total of 209 patients were diagnosed to have had a spontaneous attack of VA at Fu Wai Hospital. Of them, 27 were female, and their clinical findings were collected and compared with male patients for aspects of risk factors, clinical features and angiographical findings.

RESULTSSpontaneous attacks of VA was relatively uncommon in female (12.9%) compared with male patients. The female patients were less likely to have a history of smoking (14.8% vs. 79.7%, P < 0.001), more likely to have a family history of CAD (33.3% vs. 11.0%, P < 0.01), and to have had a greater incidence of ventricular fibrillation during attack (11.1% vs. 2.2%, P < 0.05). There were no significant differences in other characteristics between the two groups.

CONCLUSIONChinese female patients who experienced a spontaneous attack of VA had the characteristics of less smoking history, more family history of CAD and higher occurrence of ventricular fibrillation than male patients.

Objective To compare the clinical characteristics and clinical outcomes in young (≤45 years) female and male coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI). Methods Angiographic and clinical data from 124 premenopausal female patients who underwent elective PCI from April 2004 to February 2008 were compared to age-matched 430 male patients who underwent elective PCI between 2006 and 2007 in our department. All patients were treated according to guidelines and coronary angiography was repeated after 6 months. One year clinical follow-up were performed in all patients. Results Incidences of dyslipidemia, the history of myocardial infarction and smoking were significantly lower in female patients than in male patients (all P < 0.01 ). Left main, left anterior descending and bifurcation lesions were more common while type C lesion and right coronary lesion were less common in young female CAD group compared to young male CAD group (P <0. 01 -0. 05). The average lesion length in female patients was significantly longer than that in male patients [ (20. 36±13.37)mm vs.( 23.04±13.86) mm, P < 0. 05 ]. The in-hospital and follow-up incidences of major adverse cardiac events,stent thrombosis and in-stent restenosis were similar between young female and male CAD patients.Conclusions CAD risk factors were less and vessel lesions were more likely to be found at left main, left anterior descending and bifurcation in young female CAD patients compared to young male CAD patients.The clinical outcomes were similar between young female and male CAD patients.

Objective To explore the correlation between plasma BNP level and left ventricular dysfunction parameters in patients with acute myocardial infarction (AMI). Methods Plasma BNP level was determined in 230 consecutive inpatients with AMI and 111 normal controls. Patients were grouped according Killip grades, LVEF and LVEDd, respectively. BNP was transformed into lnBNP for the normal distribution. The receiver operator characteristic curve (ROC curve) was drawn to determine the best threshold and criteria for diagnosing heart failure. Results After AMI, lnBNP levels increased significantly in proportion with increasing Killip grades (Ⅰ-Ⅲ), and decreasing LVEF(all P<0.05). lnBNP level was significantly higher in LVEDd 55 mm group than in the LVEDd < 55 mm group (P<0.01). lnBNP, LVEDd and LVEF all linearly correlated with Killip grades (P<0.05) and the best correlation was shown between lnBNP and Killip grades(r=0.53, P<0.05). lnBNP also positively correlated with LVEDd(r=0.17 ,P<0.05) and negatively correlated with LVEF(r=-0.41, P<0.01). Among the parameters, InBNP level presented the largest AUC in their ROC curves(P<0.01)for diagnosing decompensated heart failure and cardiogenic shock. The sensitivity, specifiticity and accuracy rates for diagnosing decompensated heart failure were 84.9%, 45.0% and 70.0% respectively by lnBNP at the cut point of 140 ng/L The sensitivity, negative predicting value and accuracy rate for diagnosing cardiac shock were 82.8% ,66.7% and 67.4% respectively by BNP at the cut point of 400 ng/L. Conclusion lnBNP level in hospitalized patients with AMI was positively correlated with Killip grades and LVEDd,negatively correlated with LVEF and could serve as a parameter for diagnosing the decompensated heart failure and excluding the cardiac shock.

OBJECTIVETo investigate the therapeutic effectiveness of intracoronary transplantation of autologous bone marrow mononuclear cells (BM-MNC) on myocardial ischemia reperfusion injury in mini-swine model.

METHODSMyocardial ischemia reperfusion injury model was established by ligating in 16 mini-swines, which were further randomized into two groups: (3.54 +/- 0.90) x 10(8) BM-MNC was intracoronarily transplanted in BM-MNC group (n = 9), and phosphate buffer saline was intracoronarily applied in the control group (n = 7). Ultrasonic cardiograhpy, hemodynamics, neovascular density, and myocardium infarction size were evaluated before and 4 weeks after transplantation.

RESULTSIn BM-MNC group, left ventricular ejection fraction (LVEF), intra-ventricular septa, lateral wall and anterior wall, cardiac output (CO) and + dp/dt(max) had no significant differences before and 4 weeks after transplantation (P > 0.05). In the control group, LVEF, intraventricular septa, lateral wall and anterior wall, CO, and + dp/dt(max) significantly decreased 4 weeks after transplantation (P < 0.05). Left ventricular end-diastolic pressure and- dp/dt(max) had no significant differences before and after cell transplantation. Capillary density was significantly larger in the BM-MNC group than in the control group [(13.39 +/- 6.96) /HP vs. (3.50 +/- 1.90) /HP]. The percentage and size of myocardial infarction was significantly lower in the BM-MNC group than in the control group.

CONCLUSIONTransplantation of BM-MNC into the myocardial ischemic reperfusion-injury area can increase capillary density and decrease infarction area, and thus remarkably improve cardiac systolic function.
