BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), as conventionally recognized, is a metabolic disorder largely confined to residents of affluent industrialized Western countries. However, obesity and insulin resistance are not restricted to the West, as witnessed by their increasingly universal distribution. In particular, there has been an upsurge in metabolic syndrome in the Asia-Pacific region, although there are critical differences in the extent of adiposity between Eastern and Western populations. DATA SOURCES: An English-language literature search using PubMed (1999-2007) on obesity, metabolic syndrome and NAFLD, focusing on Asian definitions and Asian studies. RESULTS: NAFLD appears to be of long-standing insulin resistance and likely represents the hepatic manifestation of the metabolic syndrome. With insulin resistance as a common factor, the disease is associated with atherosclerosis and cardiovascular risk. All features of the metabolic syndrome and related events are assessed for practical management of NAFLD, although the criteria for the diagnosis of obesity and central obesity differ across racial groups. CONCLUSIONS: The increasing prevalence of obesity, coupled with diabetes, dyslipidemia, hypertension and ultimately metabolic syndrome, puts a very large population at risk of developing NAFLD in the coming decades. The simultaneous identification and appropriate treatment of the components of metabolic syndrome are crucial to reduce hepatic as well as cardiovascular morbidity and mortality.

Chinese Medical Journal 2005年第21期118卷 1773-1778页

作者： LIU Xing-peng LONG de-yong DONG Jian-zeng LIU Xiao-qing FANG Dong-ping HAO peng MA Chang-sheng department of Cardiology Beijing Anzhen Hospital Capital University of Medical Science Beijing 100029 China

Background Recurrent atrial tachyarrhythmia （ATa） after circumferential pulmonary vein ablation （CPVA） includes atrial tachycardia （AT） and atrial fribrillation （AF）. However, whether there are some differences in clinical course and mechanisms between the recurrent AT and the recurrent AF remained unclear. This study was conducted to investigate the incidence, mechanism, clinical course of the recurrent AT and AF in patients under *** One hundred and thirty consecutive patients （M/F = 95/35 ） with highly symptomatic ano multiple antiarrhythmic drugs （AADs） refractory paroxysmal （ n = 91 ） or persistent （ n = 39 ） AF were included. The ablation protocol consisted solely of two continuous circular lesions around the ipsilateral pulmonary veins （PV） guided by CARTO system. The endpoint of CPVA is PV isolation. For patients with recurrent ATa within 2 months after the initial procedure, cardioversion with direct current was attempted if the ATa lasted for more than 24 hours. A repeat ablation procedure was performed only for patients with AADs refractory recurrent ATa and at least followed up for 2 months after the initial *** Within 2 months after the initial procedure, 52 patients （40. 0% ） had experienced episodes of symptomatic recurrent ATa. Among them, 23 patients （44.2%） with recurred AT alone （AT group ）, 14 patients （26.9%） with recurred AF alone （AF group）, and 15 patients （28.8%） with recurred AT and AF （AT plus AF group）. The delayed cure rate （65.2%） in AT group was significant higher than that in AF group （21.4%, P〈0.05） and AF plus AT group （26.7%, P 〈0.05）. A repeat ablation was performed in 21 patients, including 6 patients with recurrent AT alone, 8 patients with recurrent AF alone, and 7 patients with recurrent AF plus AT. The mean number of PV gaps was 1.2 ± 0. 4 in AT group, which was significantly lower than that in AF group （2.6 ± 0. 7, P 〈 0.05） and AF plus AT group （2.0 ± 0.6, P 〈 0.05）. delayed cure rate and number of PV

Image integration system to guide catheter ablation of atrial tachycardia with a multi-key-isthmus reentrant in a patient with a repaired atrial septal defect： a case report

引用

Chinese Medical Journal 2008年第9期121卷 859-861页

作者： YU Rong-hui DONG Jian-zeng LIU Xing-peng LONG de-yong KANG Jun-ping MA Chang-sheng department of Cardiology Beijing Anzhen Hospital Capital Medical University Beijing 100029 China

Recurrent atrial tachycardia （AT） is often observed late .after heart surgery and it contributes significantly to the morbidity and mortality of this group of patients. In patients with structurally normal hearts the most prevalent type of AT is a macroreentrant atrial tachycardia （MAT）, more specifically known as common atrial flutter （AFL）. In contrast, in patients with repaired structural heart disease other ATs may occur due to the existence of variable and multiple arrhythmogenic substrates, related to the underlying heart disease and/or the surgical incisions.

Background Pulmonary vein （PV） isolation has been developed to treat patients with atrial fibrillation （AF）, and the electrophysiological endpoint of PV isolation is the disappearance or dissociation of pulmonary vein potentials （PVPs）. Pulmonary vein tachycardia （PVT） is the dissociated PV rhythm with a rapid rate. However, the characteristics and significance of PVT after pulmonary vein isolation in patients with AF remains unclear. Methods From June 2003 to June 2005, a total of 285 consecutive patients with drug refractory AF were included in this study, and they underwent segmental pulmonary vein ablation （SPVA） or circumferential pulmonary vein ablation （CPVA）. PV isolation was the initial endpoint for both approaches with documenting disappearance or dissociation of PVPs. PVT was characterized as dissociated activities within PVs with a circle length （CL） of 〈300 ms, and was classified into organized PVT or disorganized PVT according to the variance of CL. Systematic follow-up was conducted after initial procedures. Continuous variables were analyzed by Student＇s t test and categorical variables were analyzed by chi-square test. Results Three hundred and fifteen PVs were ablated in 85 patients underwent SPVA approach, 400 circular lesions surrounding ipsilateral PVs （including 790 PVs） were produced in the rest of 200 patients received CPVA approach. Electrical isolation was achieved in all of these PVs. Of these, PVPs were abolished in 89.8% （992/1105） of the ablated PVs, dissociated PV rhythms were documented in the rest 10.2 % （113/1105） of the treated PVs. Among the 113 dissociated PV rhythms, 28 met the criteria of PVT with mean CL of （155±43） ms （2 PYTs in 2 patients received SPYA, 26 PYTs in 18 patients underwent CPVA）. PVT was more frequently documented in patients underwent CPVA approach [9.0% （18/200） vs 2.3% （2/85）, P=0.04]. During the 6-month follow-up, it was indicated that no significant difference existed in AF free rate between patients wi

2009年美国糖尿病学会(ADA)和欧洲糖尿病研究学会(EASD)关于T2DM治疗的共识,及2007年中国糖尿病治疗指南均指出,生活方式干预和优化口服降糖药(OAD)控制血糖不佳时,应首选基础胰岛素治疗。但在临床实践中,预混胰岛素联合1～2种OADs治疗方案占目前胰岛素治疗的主导地位。研究显示,既往预混胰岛素控制不佳的患者转换成甘精胰岛素加OADs继续治疗时,血糖进一步改善。转换治疗后注射次数少,使用简便,同时体重无增加,因此患者满意度明显提高。

目的探讨胰升血糖素样肽-1(GLP-1)对内质网应激状态下脂肪细胞内脏脂肪素表达的调节作用。方法 3T3-L1分化成熟的脂肪细胞,经thapsigargin(Tg)诱导建立内质网应激模型。脂肪细胞经Tg和/或GLP-1孵育后,收集细胞用于总RNA的提取,收集细胞液用于ELISA分析。定量PCR检测内脏脂肪素转录水平,ELISA检测其分泌水平。内质网应激发生通过测定剪切型XBP-1(sXBP-1)表达水平增加来判断。使用细胞核因子κB(NF-κB)特异阻断剂PDTC预处理30min,观察NF-κB在GLP-1调节内脏脂肪素表达中的作用。结果 Tg诱导后sXBP-1表达增加,内脏脂肪素表达下降并呈剂量依赖性;同时给予GLP-1处理后,内脏脂肪素表达增加;PDTC降低内脏脂肪素基础水平,并未阻断GLP-1作用。结论 GLP-1可提升内质网应激状态下脂肪细胞内脏脂肪素的表达。

Autotransfusion in the management of cardiac tamponade occurring during catheter ablation of atrial fibrillation

引用

Chinese Medical Journal 2010年第7期123卷 961-963页

作者： GAO Ling-yun TANG Ri-bo DONG Jian-zeng LIU Xing-peng LONG de-yong YU Rong-hui JIANG Chen-xi CHEN Gang SANG Cai-hua ZHANG Xin-yong NING Man MA Chang-sheng department of Cardiology Beijing Anzhen Hospital Capital Medical University Beijing 100029 China

acute cardiac tamponade occurs in 0.1%-2% of patients undergoing catheter ablation of atrial fibrillation （AF） in experienced centers.1-4 Once it is diagnosed, emergency pericardiocentesis is required.5 With the intervention, sternotomy and open surgical repair can be avoided in the most patients6. Generally, pericardial blood is reinjected directly back into the patient through the femoral venous sheath in order to invert hemodynamic instability promptly.
