ObjectivesTo systematically review the efficacy of traditional Chinese medicine for arrhythmia caused by anthracycline drugs.MethodsPubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of traditional Chinese medicine for arrhythmia caused by anthracycline drugs from inception to October 2017. Two reviewers independently screened literature, extracted data and evaluated risk of bias of included studies. Meta-analysis was then performed by Revman 5.3 software.ResultsA total of 4 RCTs involving 312 patients were included. The results of meta-analysis showed that: the incidence of tachycardia in the Wenxin granule treatment group was lower than that in the control group (RR=0.35, 95%CI 0.18 to 0.67, P=0.002). Baoxinkang was more effective than antioxidant western medicine in protecting myocardial SOD activity (RR=2.25, 95%CI 1.74 to 2.76, P<0.000 01). But there was no significant difference between two groups on the incidence of atrial premature beats (RR=0.40, 95%CI 0.15 to 1.08,P=0.07), premature ventricular contractions (RR=0.56, 95%CI 0.23 to 1.34, P=0.19) and atrial fibrillation (RR=0.41, 95%CI 0.11 to 1.53, P=0.18). In addition, there was no significant difference between Wenxin granules and amiodarone in treating arrhythmia induced by anthracycline. The addition of Wenxin granules on the basis of anthracycline antitumor chemotherapy regimens was not effective in delaying disease progression compared with anthracycline alone. Wenxin granules could not change the SOD level of breast cancer patients with cardiotoxicity caused by anthracycline chemotherapy, compared with chemotherapy and basic treatment.ConclusionsThe current evidence shows that Wenxin granules can prevent and reduce anthracycline-induced tachycardia, but its efficacy in improving the overall efficiency, preventing and reducing atrial premature beats, premature ventricular contractions, atrial fibrillation, and SOD levels are unclear. Baoxinkang can protect myocardial SOD activity. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
【摘要】 目的 探讨B型超声对肺不张的诊断价值。 方法 对2007年5月-2009年5月收治的67例肺不张患者的CT诊断与B型超声诊断进行对照、分析、总结。 结果 B型超声诊断一侧肺不张和肺叶肺不张与CT诊断符合率为94.64%，肺段型肺不张诊断符合率为54.55%。 结论 B型超声诊断可作为肺不张筛查的首选诊断方法。【Abstract】 ObjectiveT o study the diagnostic value of atelectasis by type-B ultrasonography. Methods Data of 67 cases of patients with atelectasis diagnosed by type-B ultrasonography and CT were compared, analyzed, and summarized between May 2007 and May 2009. Results The diagnosis coincidence rate which was got by comparing ultrasonography diagnosis of the one side atelectasis and pulmonary lobectomy atelectasis with CT diagnosis was 94.64%, and that of pulmonary segmental atelectasis was 54.55%. Conclusion Type-B ultrasonography can be used as the preferred screening atelectasis diagnosis.
ObjectiveTo systematically review the efficacy and safety of pericarpium trichosanthis injection combined with conventional western medicine for angina pectoris.MethodsDatabases including CBM, CNKI, WanFang Data, VIP, PubMed, The Cochrane Library and Web of Science were searched from inception to February 20th 2017 to collect randomized controlled trials (RCTs) about pericarpium trichosanthis injection combined with conventional western medicine for angina pectoris. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software.ResultsA total of 10 RCTs involving 1 004 patients were included. The results of meta-analysis showed that: the effective rate of angina symptoms (RR=1.24, 95%CI 1.15 to 1.33, P<0.000 01) and resting ECG (RR=1.30, 95%CI 1.15 to 1.45, P<0.000 1) in pericarpium trichosanthis injection combined with conventional western medicine group were superior to the conventional western medicine group. And the adverse reaction was rare and could be more tolerated in pericarpium trichosanthis injection combined with conventional western medicine group.ConclusionPericarpium trichosanthis injection combined with conventional western medicine can improve the symptoms of angina pectoris and objective indicator of ECG. However, due to the low quality of included studies and lack of evidence, the above results are needed to be validated by further well-designed multicenter, large scale, double blind RCTs.
Objective To understand the current situation of healthcare-associated infection (HAI) in comprehensive hospitals with a number of beds≥900, and provide a reference for the next step in formulating HAI prevention and control measures. Methods The data on the prevalence rate of HAI in comprehensive hospitals with a number of beds≥900 of Yunnan Province between 2020 and 2022 were retrospective collected. The HAI situation and trend in each year were analyzed. Results A total of 119 comprehensive hospitals were included, with 166 745 patients surveyed and 3 237 cases of HAI. Lower respiratory tract infection and urinary tract infection were the most common sites. The department with the highest incidence of hospital infections was the intensive care unit, followed by neurosurgery and hematology. The prevalence rates of HAI showed a downward trend from 2020 to 2022 (2.08% vs. 1.99% vs. 1.79%, χ2=14.301, P<0.001). A total of 1 315 strains of hospital-acquired pathogens were detected, all of which were mainly Gram-negative bacteria, with Escherichia coli and Klebsiella pneumoniae being more common. The rate of antibiotics use and the rate of pathogen testing showed an upward trend from 2020 to 2022 (χ2=79.233, 23.866, P<0.001), the infection rate of incision site and the prophylactic use rate of antimicrobial drugs in patients with class Ⅰ surgery both showed a decreasing trend (χ2=15.551, 6.311, P<0.05). Conclusions The prevalence of infection in comprehensive hospitals of Yunnan Province is decreasing. But the supervision of key departments, the implementation of pathogen prevention and control measures, and the rational use of antibiotics in inpatients are still the focus of future work.
