ObjectiveTo systematically review the predictive factors of new-onset conduction abnormalities(NOCAs) after transcatheter aortic valve replacement (TAVR) in bicuspid aortic valve (BAV) patients. MethodsThe CNKI, VIP, WanFang Data, PubMed, Cochrane Library and EMbase databases were electronically searched to collect the relevant studies on NOCAs after TAVR in patients with BAV from inception to December 5, 2022. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 software. ResultsSix studies involving 758 patients with BAV were included. The results of the meta-analysis showed that age (MD=?1.48, 95%CI ?2.73 to ?0.23, P=0.02), chronic kidney disease (OR=0.14, 95%CI 0.06 to 0.34, P<0.01), preoperative left bundle branch block (LBBB) (OR=2.84, 95%CI 1.11 to 7.23, P=0.03), membranous septum length (MSL) (MD=0.93, 95%CI 0.05 to 1.80, P=0.04), implantation depth (ID) (MD=?2.06, 95%CI ?2.96 to ?1.16, P<0.01), the difference between MSL and ID (MD=3.05, 95%CI 1.92 to 4.18, P<0.01), and ID>MSL (OR=0.27, 95%CI 0.15 to 0.49, P<0.01) could be used as predictors of NOCAs. ConclusionCurrent evidence shows that age, chronic kidney disease, LBBB, MS, ID, the difference between MSL and ID, and ID>MSL could be used as predictors of NOCAs. Due to the limited quantity and quality of included studies, more high-quality studies are required to verify the above conclusion.
ObjectiveTo explore the correlation of pretreatment systemic immune inflammation index (SII) with prognosis in esophageal cancer patients.MethodsWe searched the PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP, Chinese Biology Medicine, and Wanfang databases to identify eligible studies evaluating the relation between pretreatment SII and prognosis in patients with esophageal cancer from establishment of databases to December 2018. SII was defined as the absolute neutrophil count multiplied by the absolute platelet count divided by the absolute lymphocyte count. The primary endpoint was overall survival (OS), and the secondary endpoints were cancer-specific survival and disease-free survival. The Stata 12.0 software was applied for the meta-analysis, and the hazard ratio (HR) and 95% confidence interval (CI) were assessed.ResultsA total of six retrospective studies involving 2 376 esophageal cancer patients were included and all patients were from China or Japan. The results revealed that elevated pretreatment SII was significantly associated with poor OS in esophageal cancer [HR=1.50, 95%CI (1.15, 1.95), P=0.002]. Subgroup analyses of OS indicated that SII had a high prognostic value in patients who received surgery [HR=1.54, 95%CI (1.14, 2.08), P=0.005] and were diagnosed as esophageal squamous cell carcinoma [HR=1.50, 95%CI (1.11, 2.02), P=0.007]; however, no significant relation was observed between SII and prognosis in esophageal cancer patients who were treated with radiotherapy [HR=1.318, 95%CI (0.611, 2.841), P=0.482]. Furthermore, compared with neutrophil to lymphocyte ratio and platelet to lymphocyte ratio, SII showed a higher predictive value for the prognosis of esophageal cancer.ConclusionsPretreatment SII may serve as an independent risk factor for prognosis of Chinese and Japanese esophageal cancer patients, especially patients who were treated with surgery and with esophageal squamous cell carcinoma. However, more prospective studies with big samples from other countries or regions are still needed to verify our findings.

Methods: We searched the PubMed,VIP and CNKI databases, manual collection of clinical study about allergic rhinitis treatment of montelukast, based on inclusion and exclusion criteria for pooling of literature, Jadad scale used for quality assessment of the literature. Then use Revman4.2 Meta analysis software to evaluate the overall effectiveness. Results: Nine RCT clinical study have been included, The results showed that montelukast group was higher than control group on efficient control, Heterogeneity test showed that the subgroup and its total effective rate is Pgt;01,I2lt;50%. Therefore, we adopted a fixed effects model. After 2 weeks montelukast group and the control group no significant difference (Pgt;0.1). But after 2,3 month the two groups were statistically significant differences(Plt;0.000 01). On a comprehensive analysis of the three subgroups, montelukast group and the control group statistically significant differences(Plt;0.000 01), adverse drug reactions was no significant difference. Conclusion: The available clinical evidence to show that montelukast for the treatment of allergic rhinitis and effective, However, due to the existence of selection and measurement bias, This may affect the outcome of the argument strength.Therefore look forward to more highquality randomized and doubleblind controlled trials to provide highquality evidence.
Objective To review the current state of lung rehabilitation in China and explore the effect of lung rehabilitation on chronic respiratory diseases. Methods Database of CNKI ( 1979-2009) , VIP Chinese Periodical Database ( 1989-2009 ) , and Wanfang Data ( 1982-2009) resources were searched. Studies of lung rehabilitation were collected, and randomized and controlled trials were included. Data were extracted on study population, interfering and evaluating methods. The meta-analyses were performed by using RevMan 4. 2 software. The heterogeneity was analyzed by X2 and P value. Results A total of 3 clinical trials met the inclusion criteria. The study population were all severe and very severe chronic obstructive pulmonary diseases ( COPD) patients. Lung rehabilitation could improve daily activity( WMD:1. 29, 95% CI: 1. 05-1. 54) and dyspnea level ( SMD: - 1. 27, 95% CI: - 1. 67 to - 0. 86) of COPD patients. Conclusion The general level of studies on lung rehabilitation is not satisfied. Meta-analysis comfirmes that lung rehabilitation is beneficial in improving daily activity and dyspnea level of COPD patients.
The incidence of tinnitus is very high, which can affect the patient’s attention, emotion and sleep, and even cause serious psychological distress and suicidal tendency. Currently, there is no uniform and objective method for tinnitus detection and therapy, and the mechanism of tinnitus is still unclear. In this study, we first collected the resting state electroencephalogram (EEG) data of tinnitus patients and healthy subjects. Then the power spectrum topology diagrams were compared of in the band of δ (0.5–3 Hz), θ (4–7 Hz), α (8–13 Hz), β (14–30 Hz) and γ (31–50 Hz) to explore the central mechanism of tinnitus. A total of 16 tinnitus patients and 16 healthy subjects were recruited to participate in the experiment. The results of resting state EEG experiments found that the spectrum power value of tinnitus patients was higher than that of healthy subjects in all concerned frequency bands. The t-test results showed that the significant difference areas were mainly concentrated in the right temporal lobe of the θ and α band, and the temporal lobe, parietal lobe and forehead area of the β and γ band. In addition, we designed an attention-related task experiment to further study the relationship between tinnitus and attention. The results showed that the classification accuracy of tinnitus patients was significantly lower than that of healthy subjects, and the highest classification accuracies were 80.21% and 88.75%, respectively. The experimental results indicate that tinnitus may cause the decrease of patients’ attention.
Objective To investigate the potential causal associations between 731 immune cell traits and atherosclerosis by Mendelian randomization (MR) analysis. Methods Using single nucleotide polymorphisms (SNPs) as instrumental variables, genome-wide association study (GWAS) summary statistics (GCST90001391 to GCST90002121) for 731 immune cell traits were obtained from the GWAS Catalog database, and the atherosclerosis dataset (finn-b-I9_CORATHER) was retrieved from the IEU database for MR analysis. The inverse variance weighted method, MR-Egger regression, weighted median, simple mode, and weighted mode approaches were employed to estimate the causal effects between the 731 immune cell traits and atherosclerosis, using odds ratio (OR) with 95% confidence interval (CI) as the effect size. Cochran Q test was used to assess heterogeneity. Horizontal pleiotropy was evaluated using the MR-Egger intercept test and the MR-PRESSO method. Leave-one-out analysis was conducted to examine the sensitivity of the causal estimates to individual SNPs. Results MR analysis revealed potential causal associations between 24 immune cell traits and atherosclerosis (P<0.05). Among them, human leucocyte antigen (HLA)-DR on plasmacytoid dendritic cells (DC) [OR=1.035, 95%CI (1.016, 1.054), P<0.001] and hematopoietic stem cell absolute count (HSCAC) [OR=1.049, 95%CI (1.021, 1.077), P<0.001] showed significant positive causal associations with atherosclerosis (P≤0.001), whereas CD86 on CD62L+ myeloid DC [OR=0.953, 95%CI (0.926, 0.981), P=0.001] exhibited a significant negative causal association with atherosclerosis (P≤0.001). The results of Cochran Q test, MR-Egger regression, and MR-PRESSO indicated P-values>0.05, suggesting no evidence of heterogeneity or horizontal pleiotropy in the causal estimates for these three immune cell traits. Reverse MR analysis, using the 24 immune cell traits as outcome variables, showed no evidence of causal association (P>0.05), supporting a unidirectional causal relationship from immune cells to atherosclerosis. Conclusion HLA-DR on plasmacytoid DC and HSCAC may serve as risk factors for atherosclerosis, while CD86 on CD62L+ myeloid DC may play a protective role against atherosclerosis.
