引用

Journal of Geriatric Cardiology 2018年第6期15卷 441-450页

作者： Wei LIU Qiang WU Xiao-Jie YANG Jing Huang Department of Cardiology Guizhou Provincial People's Hospital Guiyang China Department of Endocrinology Guizhou Provincial People's Hospital Guiyang China

Objective To evaluate the trend of change in the efficacy and safety of catheter ablation compared with antiarrhythmic drug therapy （ADT） for rhythm control in patients with atrial fibrillation （AF） over time. Methods The online databases PubMed and EMBASE were searched for relevant studies. STATA software （version 12.0） was used to perform the meta-analysis and meta-regression. Results Fifteen randomized controlled trials including 2249 patients with AF were identified. The pooled results showed that catheter ablation was associated with a 52% reduction in the risk of AF recurrence compared with ADT [risk ratio （RR） = 0.48, 95% confidence interval （CI）： 0.40-0.57, I2 = 70.7%）. Subgroup analyses showed that catheter ablation exhibited less efficacy in studies after 2011 compared to studies before 2011 （RR = 0.61, 95% CI： 0.54-0.68, I2 = 9.3% and RR = 0.34, 95% CI： 0.24-0.47, I2 = 69.9%, respectively）, and the safety outcome showed a 1.08-fold higher incidence of adverse events （14.2% vs. 7.3%; RR = 1.08, 95% CI： 1.04-1.13） in studies after 2011. Conclusions Catheter ablation appears to be superior to ADT for rhythm control. However, less efficacy and a higher rate of adverse events were observed in studies after 2011 compared to studies before 2011.

World Journal of Gastroenterology 2014年第5期20卷 1371-1376页

Microcystic/reticular schwannoma is a recently described variant of schwannoma with a predilection for the gastrointestinal tract. Due to overlapping features with other tumors, unawareness of this tumor type may lead to diagnostic and therapeutic pitfalls. We here report a case of microcystic/reticular schwannoma arising in the meso-appendix of a 43-year-old woman. The tumor was incidentally discovered by computed tomography scan for unrelated reasons. A laparoscopic operation was performed shortly after admission. Histological examination revealed a circumscribed tumor with a striking microcystic and cribriform architecture. Immunohistochemically, the tumor cells were diffusely positive for S100 protein, glial fibrillary acid protein and protein gene product 9.5, which were consistent with a peripheral nerve sheath tumor. The patient remains well with no signs of recurrence at a 10-mo follow-up. To our knowledge, this is the first case of microcystic/reticular schwannoma arising in the meso-appendix. Albeit very rare, microcystic/reticular schwannoma should be included in the differential diagnosis of appendiceal tumors.

To investigate the relationship between natural killer（NK） cells and traumatic brain injury（TBI）, we tracked an established phenotype of circulating NK cells at several time points in patients with different grades of TBI. In serial peripheral blood samples, NK cells were prospectively measured by flow cytometry of CD3-CD56＋ lymphocytes. Compared to healthy controls, TBI patients had reductions in both the percentage and the absolute number of NK cells. Furthermore, the magnitude of NK cell reduction correlated with the degree of TBI severity at several time points. That is, NK cell population size was independently associated with lower Glasgow Coma Scale scores. In addition, at some time points, a positive correlation was found between the NK cell counts and Glasgow Outcome Scale scores. Our results indicate that TBI induces a reduction in the number of NK cells, and the magnitude of the reduction appears to parallel the severity of TBI.

Genetic basis of adult-onset nephrotic syndrome and focal segmental glomerulosclerosis

引用

Frontiers of Medicine 2017年第3期11卷 333-339页

作者： Jian Liu Weiming Wang Institute of Nephrology Shanghai Jiao Tong University School of Medicine Shanghai 200025 China Department of Nephrology Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine Shanghai 200025 China

Nephrotic syndrome （NS） is one of the most common glomerular diseases with signs of nephrosis, heavy proteinuria, hypoalbuminemia, and edema. Dysfunction of glomerular filtration barrier causes protein loss through the kidneys. Focal segmental glomerulosclerosis （FSGS） accounts for nearly 20% of NS among children and adults. Adult-onset FSGS/NS is often associated with low response to steroid treatment and immunosup- pressive medication and poor renal survival. Several genes involved in NS and FSGS have been identified by linkage analysis and next-generation sequencing. Most of these genes encode proteins and are highly expressed in glomerular podocytes, which play crucial roles in slit-diaphragm signaling, regulation of actin cytoskeleton dynamics and maintenance of podocyte integrity, and cell-matrix interactions. In this review, we focus on the recently identified genes in the adult-onset NS and FSGS and discuss clinical significance of screening of these genes.

New predictors of in-stent restenosis in patients with diabetes mellitus undergoing percutaneous coronary intervention with drug-eluting stent

引用

Journal of Geriatric Cardiology 2018年第2期15卷 137-145页

作者： Jian-Long WANG Zheng QIN Zhi-Jian WANG Dong-Mei SHI Yu-Yang LIU Ying-Xin ZHAO Li-Xia YANG Wan-Jun CHENG Yu-Jie ZHOU Department of Cardiology Beijing Anzhen Hospital Capital Medical University Beijing China

Background Percutaneous coronary intervention （PCI） had become the major therapeutic procedure for coronary artery disease （CAD）, but the high rate of in-stent restenosis （ISR） still remained an unsolved clinical problem in clinical practice. Increasing evidences suggested that diabetes mellitus （DM） was a major risk factor for ISR, but the risk predictors of ISR in CAD patients with DM had not been well characterized. The aim of this study was to investigate the clinical and angiographic characteristic predictors significantly associated with the occurrence of ISR in diabetic patients following coronary stenting with drug-eluting stent （DES）. Methods A total of 920 patients with diabetes who diagnosed CAD and underwent coronary DES implantation at Beijing Anzhen Hospital in china were consecutively enrolled from January 2012 to December 2012. Of these, 440 patients underwent the second angiography within ≥ 6 months due to the progression of treated target lesions. Finally, 368 of these patients who met the inclusion and exclusion criteria were followed up by angiography after baseline PCI. According to whether ISR was detected at follow-up angiography, patients were divided into the ISR group （n = 74） and the non-ISR group （n = 294）. The independent predictors of ISR in patients with DM were explored by multivariate Cox＇s proportional hazards regression models. Results A total of 368 patients （260 women and 108 men） with a mean ages of 58.71 ± 10.25 years were finally enrolled in this study. Of these, ISR occurred in 74/368 diabetic patients （20.11%） by follow-up angiography. Univariate analysis showed that most baseline characteristics of the ISR and non-ISR group were similar. Patients in the ISR group had significantly higher serum very low density lipoprotein cholesterol （VLDL-C）, triglyceride （TG） and uric acid （UA） levels, more numbers of target vessel lesions, higher prevalence of multi-vessel disease, higher SYNTAX score, higher rate of previous but lower r

Obstructive sleep apnea is associated with severity and long-term prognosis of acute coronary syndrome

引用

Journal of Geriatric Cardiology 2018年第2期15卷 146-152页

作者： Shuo JIA Yu-Jie ZHOU Yi YU Si-Jing WU Yan SUN Zhi-Jian WANG Xiao-Li LIU Bright Eric King Ying-Xin ZHAO Dong-Mei SHI Yu-Yang LIU Zhi-Ming ZHOU Bejing Anzhen Hospital Capital Medical University Beijing Institute of Heart Lung and Blood Vessel Disease Beijing China

Background Obstructive sleep apnea （OSA） is a common disease in patients with acute coronary syndrome （ACS） and associated with an increased risk of fatal and nonfatal cardiovascular events. However, most patients in previous study were treated with bare metal stents and the sample sizes were relatively low. The goal of this study was to evaluate the influence of OSA on the severity and prognosis of patients admitted for ACS. Methods In this prospective cohort study, we enrolled patients with ACS who were hospitalized for coronary angiogram/percutaneous coronary intervention and undergone polysomnography. We divided the patients into two groups： moderate to severe OSA group [apnea-hypopnea index （AHI）〉 15 events/h] and control group （AHI ≤ 15 events/h）. They were followed up for up 32 months. Then, we compared the ACS severity and long-term major adverse cardiovascular events （MACE） in patients with different severity of OSA. Results Five hundred and twenty nine patients were included in the final analysis, with 76% of them being men and an average age of 59 ＋ 10 years. The overall mean AHI is 29 ± 19 events/h, 70.5% of them （373/529） being with moderate to severe OSA and 29.5% （156/529） assign into control group. Compared with controls, patients with moderate or severe OSA exhibited a higher prevalence of hypertension as well as higher body mass index, SYNTAX score, Epworth score and length of hospitalization. With a median follow-up duration of 30 months, accumulative rate of MACE was also higher in patients with moderate or severe OSA than that in the control group （8.6% vs. 3.2%, P = 0.028）. After adjusting for baseline confounders by cox regression model, moderate to severe OSA was an independent risk factor of long-term MACE （P = 0.047, HR = 1.618, 95% CI： 1.069-3.869）. Conclusions The results of this study demonstrate that moderate or severe OSA is correlated with disease severity and associated with worse long-term prognosis in ACS patients. The results rai
