This study was conducted to evaluate the efficacy and safety of Simotang Oral Liquid in the treatment of functional dyspepsia in adults. "Simotang Oral Liquid" "Simotang" "Si Mo Tang" "Si Mo Tang Oral Liquid" were used for retrieval of the relevant papers from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, Springer Link, and Web of Science from database inception to June 2021. Randomized controlled trial(RCT) of Simotang Oral Liquid in the treatment of functional dyspepsia in adults was screened out for Meta-analysis which was conducted in RevMan 5.3. A total of 16 RCTs were included. Meta-analysis showed that compared with the control group, Simotang Oral Liquid increased the total response rate and lowered the traditional Chinese medicine syndrome scores, serum cholecystokinin(CCK), serum nitric oxide(NO), and incidence of adverse reactions. However, the serum substance P(SP) had no statistical difference between the two groups. Simotang Oral Liquid is effective and safe in the treatment of functional dyspepsia in adults. However, this study has evidence and limitations, so the conclusions need to be further verified by large sample and multicenter clinical studies.

Objective: To explore the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) ratio with the severity of coronary artery disease and 2-yeat outcome in patients with premature coronary heart disease. Methods: This prospective, multicenter, observational cohort study is originated from the PROMISE study. Eighteen thousand seven hundred and one patients with coronary heart disease (CHD) were screened from January 2015 to May 2019. Three thousand eight hundred and sixty-one patients with premature CHD were enrolled in the current study. According to the median LDL-C/HDL-C ratio (2.4), the patients were divided into two groups: low LDL-C/HDL-C group (LDL-C/HDL-C≤2.4, n=1 867) and high LDL-C/HDL-C group (LDL-C/HDL-C>2.4, n=1 994). Baseline data and 2-year major adverse cardiovascular and cerebrovascular events (MACCE) were collected and analyzed in order to find the differences between premature CHD patients at different LDL-C/HDL-C levels, and explore the correlation between LDL-C/HDL-C ratio with the severity of coronary artery disease and MACCE. Results: The average age of the low LDL-C/HDL-C ratio group was (48.5±6.5) years, 1 154 patients were males (61.8%); the average age of high LDL-C/HDL-C ratio group was (46.5±6.8) years, 1 523 were males (76.4%). The number of target lesions, the number of coronary artery lesions, the preoperative SNYTAX score and the proportion of three-vessel coronary artery disease in the high LDL-C/HDL-C group were significantly higher than those in the low LDL-C/HDL-C group (1.04±0.74 vs. 0.97±0.80, P=0.002; 2.04±0.84 vs. 1.85±0.84, P<0.001; 13.81±8.87 vs. 11.70±8.05, P<0.001; 36.2% vs. 27.4%, respectively, P<0.001). Correlation analysis showed that there was a significant positive correlation between LDL-C/HDL-C ratio and preoperative SYNTAX score, the number of coronary artery lesions, the number of target lesions and whether it was a three-vessel coronary artery disease (all P<0.05). The 2-year follow-up results showed that the incidence of MACCE was significantly higher in the high LDL-C/HDL-C group than that in the low LDL-C/HDL-C group (6.9% vs. 9.1%, P=0.011). There was no significant difference in the incidence of all-cause death, cardiac death, myocardial infarction, stroke, revascularization and bleeding between the two groups. Cox multivariate regression analysis showed that the LDL-C/HDL-C ratio has no correlation with 2-year MACCE, death, myocardial infarction, revascularization, stroke and bleeding events above BARC2 in patients with premature CHD. Conclusion: High LDL-C/HDL-C ratio is positively correlated with the severity of coronary artery disease in patients with premature CHD. The incidence of MACCE of patients with high LDL-C/HDL-C ratio is significantly higher during 2 years follow-up; LDL-C/HDL-C ratio may be an indicator for evaluating the severity of coronary artery disease and long-term prognosis in patients with premature CHD.

OBJECTIVE: To investigate the optimal duration of dual antiplatelet therapy (DAPT) in patients with diabetes mellitus (DM) requiring complex percutaneous coronary intervention (PCI). METHODS: A total of 2403 patients with DM who underwent complex PCI from January to December 2013 were consecutively enrolled in this observational cohort study and divided according to DAPT duration into a standard group (11-13 months, n = 689) and two prolonged groups (13-24 months, n = 1133; > 24 months, n = 581). RESULTS: Baseline characteristics, angiographic findings, and complexity of PCI were comparable regardless of DAPT duration. The incidence of major adverse cardiac and cerebrovascular event was lower when DAPT was 13-24 months than when it was 11-13 months or > 24 months (4.6% vs. 8.1% vs. 6.0%, P = 0.008), as was the incidence of all-cause death (1.9% vs. 4.6% vs. 2.2%, P = 0.002) and cardiac death (1.0% vs. 3.0% vs. 1.2%, P = 0.002). After adjustment for confounders, DAPT for 13-24 months was associated with a lower risk of major adverse cardiac and cerebrovascular event [hazard ratio (HR) = 0.544, 95% CI: 0.373-0.795] and all-cause death (HR = 0.605, 95% CI: 0.387-0.944). DAPT for > 24 months was associated with a lower risk of all-cause death (HR = 0.681, 95% CI: 0.493-0.942) and cardiac death (HR = 0.620, 95% CI: 0.403-0.952). The risk of major bleeding was not increased by prolonging DAPT to 13-24 months (HR = 1.356, 95% CI: 0.766-2.401) or > 24 months (HR = 0.967, 95% CI: 0.682-1.371). CONCLUSIONS For patients with DM undergoing complex PCI, prolonging DAPT might improve the long-term prognosis by reducing the risk of adverse ischemic events without increasing the bleeding risk.

Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (1324 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 1324 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13P=0.002). The incidence of MACCE in 1324 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

BACKGROUND: Imprecise interpretation of coronary angiograms was reported and resulted in inappropriate revascularization. Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is a comprehensive system to evaluate the complexity of the overall lesions. We hypothesized that a real-time SYNTAX score feedback from image analysts may rectify the mis-estimation and improve revascularization appropriateness in patients with stable coronary artery disease (CAD). METHODS: In this single-center, historical control study, patients with stable CAD with coronary lesion stenosis ≥50% were consecutively recruited. During the control period, SYNTAX scores were calculated by treating cardiologists. During the intervention period, SYNTAX scores were calculated by image analysts immediately after coronary angiography and were provided to cardiologists in real-time to aid decision-making. The primary outcome was revascularization deemed inappropriate by Chinese appropriate use criteria for coronary revascularization. RESULTS: A total of 3245 patients were enrolled and assigned to the control group (08/2016-03/2017, n = 1525) or the intervention group (03/2017-09/2017, n = 1720). For SYNTAX score tertiles, 17.9% patients were overestimated and 4.3% were underestimated by cardiologists in the control group. After adjustment, inappropriate revascularization significantly decreased in the intervention group compared with the control group (adjusted odds ratio [OR]: 0.83; 95% confidence interval [CI]: 0.73-0.95; P = 0.007). Both inappropriate percutaneous coronary intervention (adjusted OR: 0.82; 95% CI: 0.74-0.92; P < 0.001) and percutaneous coronary intervention utilization (adjusted OR: 0.88; 95% CI: 0.79-0.98; P = 0.016) decreased significantly in the intervention group. There was no significant difference in 1-year adverse cardiac events between the control group and the intervention group. CONCLUSIONS: Real-time SYNTAX score feedback significantly reduced inappropriate coronary revascularization in stable patients with CAD. CLINICAL TRIAL REGISTRATION Nos.

Objective: To explore the related factors of premature acute myocardial infarction(AMI), and to compare the the long-term outcomes in patients with and without premature AMI after percutaneous coronary intervention (PCI). Methods: This study was a prospective cohort study.From January 2013 to December 2013, 10 724 consecutive patients with coronary heart disease undergoing PCI in Fuwai Hospital were enrolled. Among them 1 920 patients with the diagnosis of AMI were divided into two groups: premature AMI (man≤50 years old, woman≤60 years old) and non-premature AMI. The baseline characteristics were collected, and multivariate logistic regression was uesed to analysis the related factors of premature AMI. The clinical outcomes, including the major adverse cardiovascular and cerebrovascular events(MACCE) which was the composite of cardiac death, myocardial infarction, revascularization, stroke and stent thrombosis, as well as bleeding events, during hospitalization, at 2 years and 5 years follow-up were analyzed. Results: A total of 1 920 AMI patiens were included(age was (56.5±11.3) years old)，with 1 612(84.0%) males. There were statistically significant differences between the two groups in gender, body mass index, blood lipid, complications, inflammatory markers, etc (all P<0.05). Multivariate logistic regression analysis showed body mass index(OR=1.06, 95%CI 1.01-1.10, P<0.01), triglyceride(OR=1.47, 95%CI 1.14-1.90, P<0.01), serum uric acid level(OR=1.02, 95%CI 1.01-1.04, P<0.01), high density lipoprotein cholesterol level(OR=0.33, 95%CI 0.14-0.78, P=0.01) and history of hypertension(OR=0.72, 95%CI 0.56-0.93, P=0.01) were independent related factors of premature AMI. The incidence of all-cause death and cardiac death were lower during hospitalization, at 2 years and 5 years follow-up in the premature AMI group than in non-premature AMI group(all P<0.05). In the premature AMI group, the incidence of MACCE and stroke was lower, with more bleeding events in 5 years follow-up(all P<0.05). Conclusions: Metabolic abnormalities, including high BMI, high triglyceride level and high serum uric acid, low high-density lipoprotein cholesterol level are the related factor of premature AMI. The incidence of ischemic events in patients with premature AMI is lower, while the incidence of bleeding events is higher than non-premature AMI patients.

Diemailing~® Kudiezi Injection( DKI) is widely used in the treatment of cerebral infarction,coronary heart disease and angina pectoris. Long-term clinical application and related research evidence showed that DKI has a good effect in improving the clinical symptoms of cardiovascular and cerebrovascular diseases. However,this injection has not been included in any clinical practice guideline. It has been found that the use of DKI is in wrong way in clinical practice in recent years. Therefore,clinical experts from the field of cardiovascular and cerebrovascular diseases nationwide are invited to compile this expert consensus in order to guide clinicians.GRADE system is used to grade the quality of evidence according to different outcomes according to degrading factors. Then it forms the recommendation or consensus suggestion through the nominal group method. The formation of expert consensus mainly considers six factors: quality of evidence,economy,efficacy,adverse reactions,patient acceptability and others. Based on these six aspects,if the evidence is sufficient,a " recommendation" supported by evidence is formed,and GRADE grid voting rule is adopted. If the evidence is insufficient,a " consensus suggestions" will be formed,using the majority voting rule. In this consensus,the clinical indications,efficacy,safety evidences and related preliminary data of DKI were systematically and comprehensively summarized in a concise and clear format,which could provide valuable reference for the clinical use of DKI. This consensus has been approved by China association of Chinese medicine which is numbered GS/CACM 202-2019.

Objective: To explore the impact of bundle branch block (BBB) on acute coronary syndrome (ACS) prognosis in patients after percutaneous coronary intervention (PCI). Methods: A total of 6 429 ACS patients received PCI in our hospital from 2013-01 to 2013-12 were enrolled. According to BBB diagnosis at discharge, the patients were divided into 2 groups: BBB group, n=159 and Non-BBB group, n=6 270. The incidences of 2-year major adverse cardio and cerebral-vascular events (MACCE) including all-cause death, cardiac death, myocardial infarction, revascularization, in-stent thrombosis and stroke were compared between 2 groups; relationship between existing BBB and clinical outcomes was assessed. Results: Compared with Non-BBB group, BBB group had the elder age (62.97±11.37) years vs (58.26±10.36) years, lower BMI (25.31±3.02) vs (25.89±3.20), decreased glomerular filtration rate (86.89±16.15)ml/min vs (91.05±15.53)ml/min and LVEF (59.27±9.86)% vs (62.37±7.36) %, all P<0.05; other baseline condition, angiographic and interventional features were similar between 2 groups, all P>0.05. During 2-year follow-up period, compared with Non-BBB group, BBB group showed the higher incidences of cardiac death (2.5% vs 0.7%) and in-stent thrombosis (3.1% vs 0.8%), both P<0.05; other incidences of MACCE were similar between 2 groups, all P>0.05. With adjusted propensity score matching, 2-year incidence of MACCE was similar between 2 groups, P>0.05; 2-year incidences of MACCE in BBB group including LBBB and RBBB were similar to Non-BBB group, P>0.05. Cox regression analysis revealed that BBB was not related to ACS prognosis after PCI. Conclusion: BBB was not an independent risk factor for long-term MACCE occurrence in ACS patients after PCI.

Objective To introduce an optimized practical method of making and detecting pipettes for microinjection.Methods Transfer pipette was made from hard glass capillary. We softened the hard glass capillary by rotating it in a spirit-lamp flame,then moved out from the flame and quickly pulled it into two transfer pipettes.After broken by a grinding wheel,the tip of the pipette was fire-polished by quickly touching the flame to make a fine opening.A hard glass capillary (1.0 mm,ouside diametre)was pulled into two holding pipettes by pipette Puller.The pipette shoulder was broken at desired position with a grinding wheel,then the fine pipette tip opening was heated by a microforge and shrinked into a diameter -15 μm.Injection pipette could be made directly from a capillary with filament by Puller.The solution loaded injection pipette and holding pipette were assembled into the micromanipulator and could be checked before use.We transfered both pipettes into the zygotes media drop,touched the holding pipette with the tip of the injection pipette to make a "suitable"opening.Then we switched injection pipette to the mineral oil and applied injection pressure through the injector to check whether the solution could come out of the tip smoothly and at a proper speed.It could be further verified by pronucleus microinjection of zygotes.Results The results showed that the method introduced in this paper could produce suitable pipettes for zygote microinjection.In particular,the method of detecting the opening of the injection pipette was helpful for achieving high efficiency of zygote microinjection.Conclusion The method introduced here to make and detect pipettes for microinjection is very helpful for establishing a standard microinjection manipulation procedure and improving the efficiency of zygote microinjection.
