ABSTRACT

In order to standardize the clinical diagnosis and treatment decision-making with traditional Chinese medicine for pa-tients of coronavirus disease 2019(COVID-19) and put the latest clinical study evidence into clinical practice, the international trust-worthy traditional Chinese medicine recommendations( TCM Recs) working group started the compilation of Living Evidence-based Guideline for Combination of Traditional Chinese and Western Medicine for Treatment of COVID-19 on the basis of the standards and re-quirements of WHO handbook, GRADE and RIGHT. This proposal mainly introduces the formulation methods and processes of the living guidelines in details, such as the composition of the working group, the collection and identification of clinical issues and out-comes, the production of the living systematic review and the consensus of recommendations. The guidelines will continue to monitor the clinical study evidences of TCM in the prevention and treatment of COVID-19, and conduct regular evidence updating, retrieval and screening. When there is new study evidence, the steering committee will evaluate the possibility of the evidence to change clinical practice or previous recommendations, so as to decide whether the recommendations for the guidelines shall be implemented or upda-ted. The main criteria considered in the guideline updating are as follows:(1) There are new high-quality randomized controlled trial(RCT) evidences for TCM uninvolved in the previous edition of the guidelines;(2) as for the TCM involved in the guidelines, living sys-tematic review shows that new evidence may change the direction or strength of the existing recommendations. The specific implementation of the living evidence-based guidelines will take this proposal as the study basis and framework, in order to ensure the standardization of the formulation process and methods. This will be the first exploration of the methodology for living guidelines in the field of TCM.

ABSTRACT

To assess the clinical efficacy of Chinese medical injection (CMI) for heart failure by using network Meta-analysis method. The relative randomized controlled trials (RCTs) of CMI for heart failure were retrieved from China National Knowledge Infrastructure (CNKI), WanFang Database, Chinese Biomedical Literature Database (SinoMed), PubMed, Cochrane Library and EMbase in July 2017. RCTs on the comparison of two kinds of CMIs for heart failure were included. Two researchers independently completed the literature screening, data extraction and quality evaluation according to the pre-determined inclusion and exclusion criteria, and the results were crossed checked. The data were analyzed by Win Bugs, and STATA software was used for plotting. Finally, 13 RCTs were included, involving 5 kinds of CMIs and 1 538 patients. According to the quality evaluation, the appropriate random dividing methods were reported in only two RCTs, double-blindness was used in only one RCT, and even none of the RCTs mentioned allocation concealment. Network Meta-analysis showed that Shenmai injection had the greatest effect in the clinical efficacy for patients with heart failure, which was followed by Shenfu Injection. However, Shenfu Injection was most effective in improving the patients' left ventricular ejection fraction (LVEF), which was followed by Shenmai Injection. Therefore, Shenfu Injection and Shenmai Injection had certain advantages in treating heart failure. However, due to the limited sample size and the poor literature quality, more studies were required to verify the strength of evidence. We suggest that further studies shall pay more attention to the improvement of the methodological quality, increase the follow-up period, and strengthen the observation of cardiovascular end points.

ABSTRACT

Objective To explore the impact of smoking on coronary plaque characteristics on optical coherence tomography(OCT) in young patients with acute coronary disease(ACS).Methods We assessed the atherosclerotic plaque characteristics and vulnerability by OCT and coronary angiography in 60 ACS patients aged 45 years or younger in Beijing Anzhen Hospital, from June 2014 to June 2017. The patients were divided into the smoking group(n=33) and the non-smoking group(n=27) to compare the plaque characteristics and vulnerability.Results Smoking patients showed a less extent of fibrosis(48.55%vs. 77.8%,P=0.032)and microchannels(18.2%vs. 44.4%,P=0.033), and a greater extent of plaque rupture (24.2%vs. 3.7%,P=0.033) compared with non-smoking patients. In multivariate analysis, smoking was the only independent predictors of plaque rupture(OR 8.320, 95%CI 0.969-71.435,P=0.027) and less fibrosis (OR 0.269, 95%CI 0.086-0.837,P=0.020). Conclusions Patients who are smokers have less extensive fibrosis and a greater extent of plaque rupture, showing more extensive vulnerable plaque phenotype. Therefore, smoking is one of the major risk factors of advanced cardiovascular events in young patients.

ABSTRACT

Objective: Curcumin nanoparticles lyophilized powder (CNLP) were prepared by antisolvent method which was optimized using single factor method. In this process, acetone was used as solvent, deionized water was used as antisolvent, tween-80 was used as surfactant and mannitol was used as lyoprotectant. Methods: The main factors affecting the particle size of CNLP included the concentration of curcumin, volume ratio of solvent and antisolvent, dosage of surfactant, precipitation time, stirring speed, and dosage of lyoprotectant. The contrast experiments on dissolution in vitro was done between CNLP and raw curcumin powder. Results: The mean particle size of CNLP was (172.2 ± 4.6) nm; The Zeta potential of CNLP redissolving in water was (-19.7 ± 3.7) mV. The SEM graphs indicated the raw curcumin was in irregular and massive shape and its particle size was about 20 μm. The CNLP exhibited regular block structure and its particle size was about 170 nm which was obviously reduced compared with raw curcumin. The mean particle size of CNLP obtained from laser particle analyzer was in accord with the morphology of CNLP. The saturated solubility of CNLP was 41.32 times of raw curcumin powder in deionized water, 1.74 times in simulated gastric fluid and 4.11 times in simulated intestinal fluid through saturated solubility test, respectively. The dissolution rate of CNLP was 14.51 times of raw curcumin powder in water dissolution medium, 2.33 times in simulated gastric fluid and 44.79 times in simulated intestinal fluid through dissolution determination, respectively. Conclusion: The preparation process of CNLP using antisolvent method could improve the drawback of poor water solubility and enhance the bioavailability of curcumin.

ABSTRACT

To assess the clinical effect and safety of Chinese traditional medicine injection combined with radiotherapy for esophageal cancer. The relative randomized controlled trials (RCTs) of Chinese medical injections (CMI) combined with radiotherapy as well as simple radiotherapy for esophageal cancer were searched from PubMed, Cochrane Library, EMBASE, Chinese Biomedical Literature Database(CBM), China National Knowledge Infrastructure (CNKI), Wanfang Database and VIP Database as at September 2014. Two researchers completed the data extraction and quality evaluation independently. The data were analyzed by GeMTC 0.14.3 and Stata 12. 0 software. Finally, 43 RCTs involving 3 289 patients were finally included. The star network was constructed by different comparison groups. The results of network meta-analysis showed that the seven CMIs combined with radiotherapy was superior to simple radiotherapy in the treatment of esophageal cancer in efficacy, quality of life, and reduction in the incidence of nausea and leucopenia, but with no significant difference among the seven CMIs. Probability ranking result showed a great possibility for Shenqi Fuzheng and astragalus polysaccharide injections in improving the overall response rate and quality of life, which were followed by cinobufagin and kangai injections. However, only one study was included for Shenqi Fuzheng and astragalus polysaccharide injections. Therefore, cinobufagin or kangai injections were preferred in improving the overall response rate and quality of life. Aidi or compound sophora injections were better than other CMIs in reducing? the incidences of nausea (III-IV) and leukopenia. More RCTs of Shenqi Fuzheng and astragalus polysaccharide injections combined with radiotherapy for patients with esophageal cancer were expected in the future to confirm our results. Moreover, study findings will be reported, particularly for the adverse events in radiotherapy for esophageal cancer.

ABSTRACT

<p><b>BACKGROUND</b>Dual anti-platelet treatment with aspirin and clopidogrel is established foundation for patients undergoing percutaneous coronary intervention (PCI) to prevent thrombotic events. The present study was conducted to examine whether the CYP2C19 681G > A polymorphism and cigarette smoking had independent or interactive effect on response to clopidogrel.</p><p><b>METHODS</b>Among 722 Chinese Han patients undergoing elective coronary stent placement due to stable angina pectoris, a loading dose of 300 mg clopidogrel was given to all patients and a daily maintenance dose of 75 mg for a minimum of 12 months. CYP2C19 681G > A polymorphism was genotyped. The platelet reactivity was measured by light transmittance aggregometry (LTA) with 5 µmol/L adenosine diphosphate (ADP) induced. The poor response was defined as 10% or less absolute difference between aggregation at baseline and 24 hours after loading dose of clopidogrel.</p><p><b>RESULTS</b>The results showed that the poor-response to clopidogrel was presented in 105 patients (14.5%). Overall, the genotype GA/AA carriers were likely to be poor-responsive cases (19.6% vs. 11.0%, P = 0.001) with odds ratio (OR) of 1.971 (95%CI: 1.296 - 2.998, P = 0.002), compared with the GG homozygotes. Meanwhile, compared with nonsmokers, the smokers showed lower rate of poor-response (10.9% vs. 17.3%, P = 0.015) with OR of 0.582 (95%CI: 0.374 - 0.904, P = 0.016). The smokers with GG genotype had the lowest risk with OR of 0.487 (95%CI: 0.246 - 0.961, P = 0.038) while nonsmokers with GA/AA genotype had the highest risk of poor-response with OR of 1.823 (95%CI: 1.083 - 3.068, P = 0.024), compared with nonsmokers with GG genotype. However, there was no significant interaction between genotype and smoking.</p><p><b>CONCLUSION</b>Our study indicated that both CYP2C19 polymorphism and smoking independently affected response to clopidogrel.</p>

ABSTRACT

<p><b>BACKGROUND</b>Radial artery spasm (RAS) is the most common complication in transradial coronary angiography and intervention. In this study, we designed to investigate the incidence of RAS during transradial procedures in Chinese, find out the independent predictors through multiple regression, and analyze the clinical effect of RAS during follow-up.</p><p><b>METHODS</b>Patients arranged to receive transradial coronary angiography and intervention were consecutively enrolled. The incidence of RAS was recorded. Univariate analysis was performed to find out the influence factors of RAS, and logistic regression analysis was performed to find out the independent predictors of RAS. The patients were asked to return 1 month later for the assessment of the radial access.</p><p><b>RESULTS</b>The incidence of RAS was 7.8% (112/1427) in all the patients received transradial procedure. Univariate analysis indicates that young (P = 0.038), female (P = 0.026), small diameter of radial artery (P < 0.001), diabetes (P = 0.026), smoking (P = 0.019), moderate or severe pain during radial artery cannulation (P < 0.001), unsuccessful access at first attempt (P = 0.002), big sheath (P = 0.004), number of catheters (> 3) (P = 0.048), rapid baseline heart rate (P = 0.032) and long operation time (P = 0.021) were associated with RAS. Logistic regression showed that female (OR = 1.745, 95%CI: 1.148 - 3.846, P = 0.024), small radial artery diameter (OR = 4.028, 95%CI: 1.264 - 12.196, P = 0.008), diabetes (OR = 2.148, 95%CI: 1.579 - 7.458, P = 0.019) and unsuccessful access at first attempt (OR = 1.468, 95%CI: 1.212 - 2.591, P = 0.032) were independent predictors of RAS. Follow-up at (28 +/- 7) days after the procedure showed that, compared with non-spasm patients, the RAS patients had higher portion of pain (11.8% vs. 6.2%, P = 0.043). The occurrences of hematoma (7.3% vs. 5.6%, P = 0.518) and radial artery occlusion (3.6% vs. 2.6%, P = 0.534) were similar.</p><p><b>CONCLUSIONS</b>The incidence of RAS during transradial coronary procedure was 7.8%. Logistic regression analysis showed that female, small radial artery diameter, diabetes and unsuccessful access at first attempt were the independent predictors of RAS.</p>

ABSTRACT

<p><b>OBJECTIVE</b>This study examined the levels of exhaled nitric oxide (eNO) and peripheral blood eosinophils (EOS) as well as the correlation between the two markers in children with bronchial asthma (AS),AS complicated by allergic rhinitis (AS/AR) and chronic cough variant asthma (CVA), in order to explore the value of eNOS detection in children with AS.</p><p><b>METHODS</b>The eNO level was measured using light-emitting electrochemical photometry in 12 children with AS, 29 children with AS/AR and 10 children with CVA. Peripheral blood EOS was counted by blood cell counter (Coulter JT). Forced expiratory volume in one second (FEV1) was assessed by lung function measurement. Thirty children without atopic disease and acute respiratory infection as well as without a family history of atopic diseasea served as the control group.</p><p><b>RESULTS</b>The levels of eNO and blood EOS in the AS, the AS/AR and the CVA groups were significantly higher than those in the control group (p<0.01). The AS/AR group showed increased levels of eNO (50.3 + or - 6.7 ppb) and EOS (5.9 + or -4.2 x 109 ) compared with the AS (30.5 + or - 8.8 ppb and 4.2 + or - 3.2 x 109 respectively) and the CVA groups (26.0 + or - 3.2 ppb and 3.7 + or - 6.9 x 109 respectively) (p<0.05). There were no significant differences in eNO and EOS levels between the AS and the CVA groups. The eNO level was positively correlated with the EOS level (r=0.51, p<0.05), but not with FEV1 (r=0.144, p>0.05) in the AS group.</p><p><b>CONCLUSIONS</b>NO is highly expressed in children with symptoms of atopy and can reflect the levels of eosinophilic airway inflammation in children with AS.</p>

ABSTRACT

<p><b>BACKGROUND</b>Patients aged over 85 years have been under-represented in percutaneous coronary intervention (PCI) trials despite an increase in referrals for PCI. The long-term safety and efficacy of percutaneous coronary stenting in patients aged over 85 years with acute coronary syndrome (ACS) remain unclear. Moreover it is unknown whether there are differences between bare metal stent (BMS) and drug eluting stent (DES) in this special population.</p><p><b>METHODS</b>A total of 80 patients with ACS aged over 85 years undergoing stenting (BMS group n = 21 vs DES group n = 59) were retrospectively studied. In-hospital, one year and overall clinical follow-up (12 - 36 months) of major adverse cardiac events (MACEs) including cardiac deaths, myocardial infarction, target lesion revascularization (TLR) and target vessel revascularization (TVR) as well as stroke and other major bleeding were compared between the two groups.</p><p><b>RESULTS</b>In the entire cohort, the procedure success rate was 93.8% with TIMI-3 coronary flow post-PCI in 93.8% of the vessels and the procedure related complication was 17.5%. The incidence of in-hospital MACEs in BMS group was higher (14.3% vs 6.8%, P = 0.30). The 1-year incidence of MACEs in DES group was 7.0% while there was no MACE in the BMS group. Clinical follow-up for 12 - 36 months showed that the overall survival free from MACE was 82.9% and the incidence of MACE in the BMS group was lower (5.3% vs 21.1%, P = 0.20). Multivariate regression analysis showed that the creatinine level (OR: 1.013; 95% CI: 1.006 - 1.020; P = 0.004) and hypertension (OR: 3.201; 95% CI: 1.000 - 10.663; P = 0.04) are two major factors affecting the long-term MACE.</p><p><b>CONCLUSIONS</b>Percutaneous coronary stenting in patients aged over 85 years is safe and provides good short and long-term efficacy. Patients with renal dysfunction and hypertension may have a relatively high incidence of MACE.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the changes of plasma renin activity, antidiuretic hormone and brain natriuretic peptide in chronic heart failure (CHF) and their correlation with hyponatremia.</p><p><b>METHODS</b>Plasma levels of PRA, ADH, and BNP were measured by radioimmunology in 76 CHF patients. Forty-one out of 76 CHF patients with hyponatremia and 35 CHF patients without hyponatremia were identified by serum sodium. The rates of rehospitalization within 3 months were compared in two groups.</p><p><b>RESULTS</b>Levels of plasma renin activity, ALD, and BNP in CHF patients with hyponatremia were notably higher than those in patients without hyponatremia classified by New York Heart Association (NYHA) grade II - IV: PRA [(2.7 +/- 1.0) ng.ml(-1).h(-1) vs. (1.8 +/- 0.7) ng.ml(-1).h(-1), (4.3 +/- 1.2) ng.ml(-1).h(-1) vs. (3.0 +/- 0.9) ng.ml(-1).h(-1), (5.6 +/- 1.3) ng.ml(-1).h(-1) vs. (3.5 +/- 1.1) ng.ml(-1).h(-1), respectively, P < 0.05], ADH [(59.7 +/- 17.4) ng/L vs. (48.6 +/- 15.3) ng/L, (68.4 +/- 17.6) ng/L vs. (56.3 +/- 19.2) ng/L, (75.3 +/- 20.0) ng/L vs. (51.4 +/- 16.2) ng/L, respectively, P < 0.05] and BNP [(276.4 +/- 75.2) ng/L vs. (185.3 +/- 55.3) ng/L, (380.1 +/- 113.6) ng/L vs. (258.5 +/- 62.1) ng/L, (564.0 +/- 125.2) ng/L vs. (405.3 +/- 102.9) ng/L, respectively, P < 0.05]. In the simple regression analyses, hyponatremia was negative correlated with PRA, ADH and BNP (r = -0.31, P < 0.05; r = -0.28, P < 0.05, r = -0.80, P < 0.01). The rate of rehospitalization within 3 months in hyponatremia group was higher than that in control group.</p><p><b>CONCLUSIONS</b>There is relation of hyponatremia to the changes of plasma renin activity, antidiuretic hormone and brain natriuretic peptide in chronic heart failure. Hyponatremia may accelerate the excretion of plasma PRA, ADH and BNP in chronic heart failure. Neuroendocrine activation in patients of congestive heart failure with hyponatremia is higher than that of normal natremia group.</p>
