Tongxinluo capsule in combination with conventional therapies for stable angina pectoris: A meta-analysis and systematic review.

BACKGROUND: This study aimed to assess the efficacy and safety of Tongxinluo capsule (TXLC) in combination with conventional therapies for treating stable angina pectoris (SAP) through a comprehensive meta-analysis and systematic review. METHODS: We conducted a systematic search of the China National Knowledge Infrastructure, Wanfang, VIP, PubMed, Embase, and CENTRAL databases for randomized controlled trials investigating the use of TXLC as adjuvant therapy for SAP published up to June 2023. The Cochrane Handbook was used to evaluate the risk of bias. Meta-analysis was performed using Review Manager 5.4.1, and publication bias was assessed using Begg test and Egger test in the Stata SE 12.0 software. GRADEpro was used to assess the quality of the evidence. RESULTS: This meta-analysis included 26 randomized controlled trials with a total of 2352 patients. TXLC co-administration demonstrated significant reduction in angina attack frequency (mean difference (MD) -0.91, 95% confidence interval (CI) -0.97 to -0.84, P < .00001) and duration (MD -1.71, 95% CI -2.24 to -1.19, P < .00001), decreased use of nitroglycerin tablets (MD -6.28, 95% CI -7.16 to -5.41, P < .00001), lowered C-reactive protein (MD -1.19, 95% CI -1.35 to -1.03, P < .00001) and low-density lipoprotein cholesterol levels (MD -0.68, 95% CI -0.86 to -0.51, P < .00001). TXLC co-administration did not increase gastrointestinal reactions (RR 1.17, 95% CI 0.38 to 3.57, P = .78). The Begg test and Egger test results indicated no publication bias. The evidence quality was rated as very low for frequency of angina attack, duration of angina attack, and nitroglycerin usage, and low for C-reactive protein, low-density lipoprotein cholesterol levels, and gastrointestinal reaction events. CONCLUSION: This meta-analysis supports TXLC as a beneficial adjunct treatment for SAP.

Physical Therapies for Psychosomatic Symptoms and Quality of Life Induced by Aromatase Inhibitors in Breast Cancer Patients: A Systematic Review and Meta-Analysis.

OBJECTIVE: To evaluate the effects of Physical Therapies (PTs) on improvement in psychosomatic symptoms and quality of life (QOL) in breast cancer patients. DATA SOURCES: Seven databases (MEDLINE, EMBASE, Cochrane CENTRAL, China National Knowledge Infrastructure, Wangfang, VIP, and China Biology Medicine disc databases) were systematically searched from the database inception through May 18, 2021. STUDY SELECTION: Randomized controlled trials (RCTs) which compared acupuncture or exercise with a sham control or usual care for the treatment of aromatase inhibitors (AIs)-related psychosomatic symptoms and QOL. DATA EXTRACTION AND SYNTHESIS: Data were screened and extracted independently using predesigned forms. The quality of RCTs was assessed with the Cochrane Handbook for Systematic Reviews of Interventions. The effect size was calculated via random-effects modeling. The quality of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation approach. MAIN OUTCOMES AND MEASURES: The score of pain was measured with BPI scale and Western Ontario and the McMaster Universities Index (WOMAC) scale. Emotional state was measured with Pittsburgh Sleep Quality Index (PSQI), Hospital Anxiety and Depression Scale (HADS-A), and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue). The QOL score was measured by self-reported measurements, including the Functional Assessment of Cancer Therapy-General (FACT-G) scale and 36-Item Short Form Survey (SF-36) scale. RESULTS: Eleven RCTs (with 830 patients) were included in the systematic review, and data from 10 RCTs (with 798 patients) were used in the meta-analysis. Results showed acupuncture significantly reduced worst pain scores (P < 0.00001, I 2 = 83.5%) [SMD = -0.81, 95% CI (-1.51, -0.11)], but the effect of exercise therapies was not significant in overall change in worst pain scores (P =0.006, I 2 = 72.3%) [SMD = -0.30, 95% CI (-0.76, 0.16)]. Both acupuncture and exercise resulted in little to no difference in overall change in HADS-A subscale (P = 0.026<0.05, I 2 = 79.8%) [WMD = -0.21, 95% CI (-3.44, 3.03)], PSQI subscale (P = 0.488, I 2 = 0%) [WMD = 0.98, 95% CI (-0.57, 2.53)], and FACIT-Fatigue subscale (P = 0.022<0.05, I 2 = 81.0%) [WMD = 1.6, 95% CI (-5.75, 8.94)]. Exercise (compared with usual care) was associated with improving overall change in health-related QOL (subscales of SF-36 tool) (P = 0, I 2 = 72.1%) [WMD = 7.97, 95% CI (5.68, 10.25)] and cancer-specific QOL (subscales of FACT-G tool) (P = 0.304, I 2 = 16%) [WMD = 1.16, 95% CI (0.34, 1.97)]. CONCLUSIONS AND RELEVANCE: This systematic review and meta-analysis suggested that based on moderate-level evidence, acupuncture was associated with significant reductions in pain intensity, and exercise might improve QOL in breast cancer patients treated with AIs. However, in psychosomatic symptoms such as anxiety, sleep disturbance, and fatigue, acupuncture and exercise training did not result in significant improvements.

Effect of traditional Asian exercise on patients with chronic heart failure: a protocol for network meta-analysis of randomised controlled trials.

INTRODUCTION: Chronic heart failure (CHF) is a common disease worldwide, and imposes a substantial burden to the healthcare system. In CHF, limited exercise capacity and affected mental well-being leads to a reduced quality of life (QOL). How to improve the QOL and exercise endurance is critical for patients with CHF. Exercise therapy, such as some traditional Asian exercises (TAEs) including Taichi, Baduanjin and Yoga, plays an important role in the rehabilitation of patients with CHF. TAE is suitable for the rehabilitation of patients with CHF because of its soft movements and can relax the body and mind. Studies have shown that TAE can regulate the overall health status of the body and exercise tolerance, improve QOL and reduce rehospitalisation rate in patients with CHF. However, the difference in efficacy of TAE in patients with CHF is not yet clear. The main purpose of this study is to conduct a network meta-analysis (NMA) of randomised trials to determine the impact of TAE on patients with CHF of different types, different causes and different New York Heart Association (NYHA) heart function classifications and to provide references for different types of patients with CHF to choose appropriate exercise rehabilitation therapy. METHODS AND ANALYSIS: The literature search will be retrieved from PubMed, the Cochrane Library, Embase, Web of Science, Chinese National Knowledge Infrastructure, Wanfang database, Chinese biomedical literature service system (SinoMed) and Chinese Scientific Journals Database (VIP) from the date of their inception until 1 August 2021. All randomised controlled trials that evaluated the effects of three different TAE therapies (Taichi, Baduanjin and Yoga) on patients with CHF will be included. The primary outcomes are peak oxygen uptake (peak VO2), exercise capacity (6-min walking distance) and QOL tested with the Minnesota Living with Heart Failure Questionnaire. Secondary outcomes include the levels of N-terminal pro brain natriuretic peptide, left ventricular ejection fraction, systolic blood pressure and diastolic blood pressure. For included articles, two reviewers will independently extract the data, and Cochrane Collaboration's tool will be used to assess risk of bias. We will perform the Bayesian NMA to pool all treatment effects. The ranking probabilities for the optimal intervention of various treatments (Taichi, Baduanjin or Yoga) will be estimated by the mean ranks and surface under the cumulative ranking curve. Subgroup analysis for different types, different causes and different NYHA heart function classifications of CHF will be performed. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence contributing to each network estimate. ETHICS AND DISSEMINATION: The results will be disseminated through peer-reviewed publications. They will provide useful information to inform clinicians on the potential functions of TAE in CHF, and to provide consolidated evidence for clinical practice and further research of TAE.

Traditional Chinese Medicine in Cancer Care: An Overview of 5834 Randomized Controlled Trials Published in Chinese.

BACKGROUND: Traditional Chinese medicine (TCM) is widely integrated into cancer care in China. An overview in 2011 identified 2384 randomized and non-randomized controlled trials (RCTs, non-RCTs) on TCM for cancer published in the Chinese literature. This article summarizes updated evidence of RCTs on TCM for cancer care. METHODS: We searched 4 main Chinese databases: China National Knowledge Infrastructure, Chinese Scientific Journal Database, SinoMed, and Wanfang. RCTs on TCM used in cancer care were analyzed in this bibliometric study. RESULTS: Of 5834 RCTs (477 157 cancer patients), only 62 RCTs were indexed in MEDLINE. The top 3 cancers treated were lung, stomach, and breast cancer. About 4752 RCTs (81.45%) tested TCM combined with conventional treatment, and 1082 RCTs (18.55%) used TCM alone for treating symptoms and side-effects. Herbal medicine was the most frequently used TCM modality (5087 RCTs; 87.20%). The most frequently reported outcome was symptom improvement (3712 RCTs; 63.63%) followed by quality of life (2725 RCTs; 46.71%), and biomarkers (2384 RCTs; 40.86%). The majority of RCTs (4051; 69.44%) concluded there were beneficial effects using either TCM alone or TCM plus conventional treatment compared with conventional treatment. CONCLUSION: Substantial randomized trials demonstrated different types/stages of cancer were treated by various TCM modalities, alone or in combination with conventional medicine. Further evaluation on the effects and safety of TCM modalities focusing on outcomes such as quality of life is required.

Antibodies Against Pseudomonas aeruginosa Alkaline Protease Directly Enhance Disruption of Neutrophil Extracellular Traps Mediated by This Enzyme.

Extracellular traps released by neutrophils (NETs) are essential for the clearance of Pseudomonas aeruginosa. Alkaline protease (AprA) secreted by P. aeruginosa negatively correlates with clinical improvement. Moreover, anti-AprA in patients with cystic fibrosis (CF) can help identify patients with aggressive forms of chronic infection. However, the mechanism underlying the clinical outcomes remains unclear. We demonstrated that aprA deficiency in P. aeruginosa decreased the bacterial burden and reduced lung infection. AprA degraded NET components in vitro and in vivo but did not affect NET formation. Importantly, antibodies induced by AprA acted as an agonist and directly enhanced the degrading activities of AprA. Moreover, antisera from patients with P. aeruginosa infection exhibited antibody-dependent enhancement (ADE) similar to that of the antibodies we prepared. Our further investigations showed that the interaction between AprA and the specific antibodies might make the enzyme active sites better exposed, and subsequently enhance the recognition of substrates and accelerate the degradation. Our findings revealed that AprA secreted by P. aeruginosa may aggravate infection by destroying formed NETs, an effect that was further enhanced by its antibodies.

Randomized controlled clinical study on Yiqi Liangxue Shengji prescription for intervention cardiac function of acute myocardial infarction with ischemia-reperfusion injury.

INTRODUCTION: The morbidity and mortality of acute myocardial infarction patients still remains high after percutaneous coronary intervention (PCI). Myocardial ischemia-reperfusion (MIR) injury is one of the important reasons. Although the phenomenon of MIR injury can paradoxically reduce the beneficial effects of myocardial reperfusion, there currently remains no effective therapeutic agent for preventing MIR. Previous studies have shown that Yiqi Liangxue Shengji prescription (YLS) is effective in improving clinical symptoms and ameliorating the major adverse cardiovascular events of coronary heart disease patients undergoing PCI. This study aims to evaluate the effectiveness and safety of YLS in patients with acute myocardial infarction (AMI) after PCI. METHODS: This study is a randomized, double-blinded, placebo-controlled, single-central clinical trial. A total of 140 participants are randomly allocated to 2 groups: the intervention group and the placebo group. Based on routine medications, the intervention group will be treated with YLS and the placebo group will be treated with YLS placebo. All participants will receive a 8-week treatment and then be followed up for another 12 months. The primary outcome measures are N terminal pro B type natriuretic peptide (NT-proBNP) and left ventricular ejection fraction. Secondary outcomes are plasma levels of microRNA-145, plasma cardiac enzyme, and Troponin I levels in blood samples, changes in ST-segment in ECG, Seattle Angina Questionnaire, the efficacy of angina symptoms, and occurrence of major adverse cardiac events. All the data will be recorded in case report forms and analyzed by SPSS V.17.0. DISCUSSION: The trial will investigate whether the postoperative administration of YLS in patients with AMI after PCI will improve cardiac function. And it explores microRNAs (miRNA)-145 as detection of blood-based biomarkers for AMI by evaluating the relation between miRNAs in plasma and cardiac function.

Promising Therapeutic Candidate for Myocardial Ischemia/Reperfusion Injury: What Are the Possible Mechanisms and Roles of Phytochemicals?

Percutaneous coronary intervention (PCI) is one of the most effective reperfusion strategies for acute myocardial infarction (AMI) despite myocardial ischemia/reperfusion (I/R) injury, causing one of the causes of most cardiomyocyte injuries and deaths. The pathological processes of myocardial I/R injury include apoptosis, autophagy, and irreversible cell death caused by calcium overload, oxidative stress, and inflammation. Eventually, myocardial I/R injury causes a spike of further cardiomyocyte injury that contributes to final infarct size (IS) and bound with hospitalization of heart failure as well as all-cause mortality within the following 12 months. Therefore, the addition of adjuvant intervention to improve myocardial salvage and cardiac function calls for further investigation. Phytochemicals are non-nutritive bioactive secondary compounds abundantly found in Chinese herbal medicine. Great effort has been put into phytochemicals because they are often in line with the expectations to improve myocardial I/R injury without compromising the clinical efficacy or to even produce synergy. We summarized the previous efforts, briefly outlined the mechanism of myocardial I/R injury, and focused on exploring the cardioprotective effects and potential mechanisms of all phytochemical types that have been investigated under myocardial I/R injury. Phytochemicals deserve to be utilized as promising therapeutic candidates for further development and research on combating myocardial I/R injury. Nevertheless, more studies are needed to provide a better understanding of the mechanism of myocardial I/R injury treatment using phytochemicals and possible side effects associated with this approach.

[The clinical monitoring of invasive aspergillosis in surgical intensive care unit during 10 years].

OBJECTIVE: To investigate the invasive aspergillosis (IA) status in a surgical intensive care unit (SICU). METHODS: The clinical data including general state, operation, pathogenic microorganisms, infection position, clinical situation, treatment and prognosis of patients with IA admitted to the SICU of Peking University First Hospital from January 2004 to December 2013 were retrospectively analyzed. RESULTS: 8 220 patients admitted to the SICU of Peking University First Hospital from January 2004 to December 2013 were enrolled. Of 8 220 patients, there were 29 cases experienced IA, with an incidence of 0.35%, and the incidence of hospital onset of IA infection was 0.27% (22/8 220). The incidence of hospital onset of IA infection was accounted for 6.98% (22/315) of the incidence of hospital onset of infection in SICU in the same period. Compared with 2004-2008, in 2009-2013, the incidence of hospital onset of infection was significantly decreased [3.19% (137/4 293) vs. 4.53% (178/3 927), χ² = 10.020, P=0.002], while the incidence of IA [0.56% (24/4 293) vs. 0.13% (5/3 927), χ² = 10.874, P=0.001], the incidence of hospital onset of IA infection [0.40% (17/4 293) vs. 0.13% (5/3 927), χ² = 5.556, P=0.019], and the percentage of incidence of hospital onset of IA infection according to the incidence of hospital onset of infection were increased by 5 years [12.40% (17/137) vs. 2.81% (5/178), χ² = 10.982, P=0.001]. Of 29 patients with IA, 25 cases had occurred after operation, and the majority of them were from the Department of General Surgery (13 cases), and followed by post-renal transplantation (6 cases) and post-thoracic surgery (3 cases). In the total submission of 155 specimens from 29 patients with IA, there were 17 strains isolated aspergillosis, among which included 2 strains of Aspergillus fumigatus, and 15 other un-subgrouped strains. The most common infection site was lower respiratory tract (23 cases, 79.31%). Sixteen patients were found with positive galactomannan (GM) test. In all the risk factors contributing to IA, the ratio of the long-term usage of broad-spectrum antibiotics over 4 days was the highest [36.25% (29/80)], which followed by the long-term use of hormone [18.75% (15/80)], complicated with acute kidney injury [18.75% (15/80)], liver injury [13.75% (11/80)], the long-term use of immunosuppressive orally [7.50% (6/18)], and complicated with neutropenia [5.00% (4/80)]. In 29 patients with IA, there were 28 patients received anti-fungal treatment except for 1 patient without treatment, and those were single use of itraconazole in 1 case, single use of echinocandins in 3 cases, single use of liposomal amphotericin B in 5 cases, 8 cases with voriconazole, single use of liposomal amphotericin B or echinocandins then replaced by voriconazole in 8 cases, and 3 cases of echinocandins therapy combined with voriconazole. Seventeen of 29 patients died, with a mortality rate of 58.62%. CONCLUSIONS: IA is an uncommon but increasing postoperative complication of patients in SICU in recent 5 years. The most common sites of IA were lower respiratory tract. The mortality of IA is very high. So clinicians should pay more attention to the careful monitor for IA.
