Objective To evaluate the efficacy of asarone injection in treating respiratory disease. Methods All the randomized controlled trials (RCTs) about treating respiratory disease with asarone injection were collected by searching MEDLINE (1990 to 2010), EMbase (1990 to 2010), CSJD (1989 to January 2010) and CNKI (1979 to December 2009). The assessment of methodological quality and data extraction of the included studies were performed independently by two reviewers, and Meta-analysis was conducted with RevMan 5.0 software. Results A total of 29 studies involving 3 931 patients met the inclusion criteria. The results of Meta-analysis showed that: a) Asarone injection was effective in treating respiratory diseases including bronchiolitis, chronic obstructive pulmonary diseases (COPD) and AECOPD, bronchitis and pneumonia; b) In treating bronchiolitis, asarone injection was superior to aminophylline, heartleaf houttuynia herb and virazole in total effective rate, and was similar to andrographolide in curative effect; c) In treating COPD and AECOPD, asarone injection was superior to symptomatic treatment and bromhexine in total effective rate, was similar to benzylpenicillin sodium and tablete glycyrrhiza in curative effect, and was inferior to aminophylline in total effective rate without significant difference; d) In treating bronchitis, asarone injection was superior to aminophylline and symptomatic treatment in total effective rate, and was similar to mucosolvin in curative effect; and e) In treating pneumonia, asarone injection was superior to antibiotic, ribavirin and aminophylline in total effective rate. Conclusion Asarone injection is effective in treating respiratory disease. Because of the lower methodological quality and publication bias of the included trials, it is necessary to perform more high-quality and large-scale randomized controlled trials to make the conclusion more reliable.
ObjectiveThis study applied Mendelian randomization to explore the potential causal relationship between inflammatory factors and diabetic nephropathy. MethodsSummary-level data from genome-wide association studies of inflammatory factors and diabetic nephropathy were used, and inverse variance weighted analysis was used as the primary analytical method, complemented by results from weighted median, MR-Egger regression, simple model, and median model approaches. Sensitivity analysis was used to test the reliability of the MR analysis results. ResultsIn the inverse variance weighted method, stem cell factor (OR=1.28, 95%CI 1.04 to 1.58, P=0.020) and interferon-γ (OR=1.36, 95%CI 1.10 to 1.70, P=0.005) were positively correlated with diabetic nephropathy, and diabetic nephropathy was positively correlated with interferon-inducible protein 10 (OR=0.90, 95%CI 0.83 to 0.98, P=0.012) were negatively correlated with diabetic nephropathy. Sensitivity analysis showed that MR analysis was reliable. ConclusionStem cell factors and interferon-γ are associated with an increased risk of developing diabetic nephropathy, and diabetic nephropathy decreases the expression of interferon-inducible protein 10 in vivo. Our results demonstrate a potential causal relationship between inflammatory factors and the development of diabetic nephropathy. This finding is of clinical significance for the pre-diagnosis and treatment of diabetic nephropathy.
ObjectiveTo summarize the experience and lessons of right ventricular decompression in children with pulmonary atresia and intact ventricular septum (PA/IVS) and to reflect on the strategies of right ventricular decompression.MethodsThe clinical data of 12 children with PA/IVS who underwent right ventricular decompression in our hospital from March 2015 to December 2019 were reviewed retrospectively. There were 10 males and 2 females with a median age at the time of surgery was 5 d (range, 1-627 d). Correlation analysis between the pulmonary valve transvalvular pressure gradient and changes in Z score of tricuspid valves after decompression was performed.ResultsOne patient died of refractory hypoxemia due to circulatory shunt postoperatively and family members gave up treatment. There were 2 (16.67%) patients received postoperative intervention. The pulmonary transvalvular gradient after decompression was 31.95±21.75 mm Hg. Mild pulmonary regurgitation was found in 7 patients, moderate in 2 patients, and massive in 1 patient. The median time of mechanical ventilation was 30.50 h (range, 6.00-270.50 h), and the average duration of ICU stay was 164.06±87.74 h. The average postoperative follow-up time was 354.82±331.37 d. At the last follow-up, the average Z score of tricuspid valves was 1.32±0.71, the median pressure gradient between right ventricle and main pulmonary artery was 41.75 mm Hg (range, 21-146 mm Hg) and the average percutaneous oxygen saturation was 92.78%±3.73%. Two children underwent percutaneous balloon pulmonary valvoplasty at 6 and 10 months after surgery, respectively, with the rate of reintervention-free of 81.8%. There was no significant correlation between pulmonary transvalvular gradients after decompression and changes in Z score of tricuspid valves (r=–0.506, P=0.201).ConclusionFor children with PA/IVS, the simple pursuit of adequate decompression during right ventricular decompression may lead to severe pulmonary dysfunction, increase the risk of ineffective circular shunt, and induce refractory hypoxemia. The staged decompression can ensure the safety and effectiveness for initial surgery and reduce the risk of postoperative death.
ObjectiveTo analyze the drug-resistant phenotype and genotype characteristics of carbapenem-resistant Enterobacteriaceae (CRE) in a traditional Chinese medicine hospital from 2016 to 2018, to provide guidance for clinical rational drug use and effective anti-infection treatment.MethodsA total of 2 901 Enterobacteriaceae bacteria strains isolated from January 2016 to December 2018 were selected, and CRE strains were screened by microdilution test and Kirby-Bauer methods. CRE strains with successful seed preservation and detailed clinical data were selected for carbapenemase phenotype confirmation test, drug-resistant gene amplification, and sequencing comparison.ResultsThe 101 CRE strains collected between 2016 and 2018 were mainly Klebsiella pneumonia (73.27%, 74/101) and Escherichia coli (14.85%, 15/101), and the specimens were mainly from sputum (63.37%, 64/101) and catheter urine (11.88%, 12/101). The phenotypic test results of carbapenemase showed that 94 strains were positive in modified Hodge test, with a positive rate of 93.07%, 96 strains were positive in Carba NP test, with a positive rate of 95.05%, and 98 strains were positive in modified carbapenem inactivation method test, with a positive rate of 97.03%. Drug-resistant genes were detected in 92 (91.01%) of the 101 CRE strains, sequencing results showed that 66 (65.35%) carried blaKPC-2 gene, 4 (3.96%) carried blaKPC-19 gene, 9 (8.91%) carried blaNDM-1 gene, and 13 (12.87%) carried blaNDM-5 gene. No CRE strains carrying two resistance genes were detected. Among them, Klebsiella pneumoniae strains mainly carried blaKPC-2 gene (82.43%, 61/74), and Escherichia coli strains mainly carried blaNDM-5 gene (86.67%, 13/15), which were consistent with the main epidemic genotype in China.ConclusionsIn recent three years, the CRE strains in this hospital mainly included Klebsiella pneumoniae with blaKPC-2 gene and Escherichia coli with blaNDM-5 gene. According to the results of this test, we can reasonably select antimicrobial agents in combination with the drug sensitivity report from the microbial laboratory, so as to delay the growth of drug-resistant strains and prevent hospital transmission of multidrug-resistant bacteria.
