High-mobility group box 1 exacerbates CCl4-induced acute liver injury in mice

High-mobility group box 1 (HMGB1) is a nuclear factor that can also serve as an imflammatory mediator once released into extracellular milieu. Therefore, HMGB1 has been recognized to play a pivotal role in inflammatory diseases such as sepsis, acute lung injury, ischemia reperfusion injury and type 1 diabetes. Nevertheless, its impact on carbon tetrachloride (CCl₄)-induced hepatic injury is yet to be elucidated. In the present report, we demonstrated evidence indicating that high levels of HMGB1 were not only present in the necrotic area of liver but also in the serum after CCl₄ challenge. In line with these observations, administration of exogenous recombinant HMGB1 exacerbated CCl₄-induced hepatic injury, while HMGB1 blocking antibody provided protection for mice against CCl₄-induced acute liver injury as evidenced by the decrease of serum transaminase and reduction of hepatic tissues necrosis. Mechanistic studies revealed that blockade of HMGB1 attenuated CCl₄-induced MDA accumulation along with improved SOD and GSH activity. Treatment of mice with HMGB1 neutralizing antibody also significantly inhibited the production of proinflammatory mediators TNF-α and IL-6 along with attenuated HMGB1 expression and its extracellular release. Together, our data suggest an essential role for HMGB1 in CCl₄-induced acute liver injury, while HMGB1 neutralizing antibody could be served as an effective regimen for preventing CCl₄-induced acute liver injury.     

不同剂量辛伐他汀治疗冠心病的临床疗效观察

目的观察冠状动脉粥样硬化性心脏病患者使用不同剂量辛伐他汀的疗效、安全性、对血脂斑块生长及心血管事件的影响。方法将血脂总胆固醇(TC)≥4.68mmol/L和(或)低密度脂蛋白胆固醇(LDL-C)≥2.6 mmol/L,B超检查存在不同程度颈动脉斑块形成的临床诊断为冠心病的患者(126例)按随机原则分别入选辛伐他汀80mg组(强化治疗剂量)、40mg组与20mg组(常用处方剂量)。于服药后12周及24周复查血脂,B超复查颈动脉斑块,并对心血管事件作随访登记。结果辛伐他汀80mg、40mg与20mg均能有效地降低冠心病患者血清TC及LDL-C水平,其中80mg剂量组在降TC和降LDL-C及减少心血管事件发生率方面均明显优于20mg剂量组,40mg剂量组疗效介于两组之间,三者间均存在显著差异。80mg剂量组的颈动脉斑块缩小,而40mg剂量组及20mg剂量组无颈动脉斑块缩小。三种剂量在不良反应方面无明显差异。结论辛伐他汀强化治疗剂量在治疗冠心病方面明显优于常用处方剂量;强化治疗剂量可以逆转颈动脉斑块发展。     

Persistence of Efficacy of 0.1% Cyclosporin A Cationic Emulsion in Subjects with Severe Keratitis Due to Dry Eye Disease: A Nonrandomized,Open-label Extension of the SANSIKA Study

Purpose

Results from a 6-month double-masked and a 6-month open-label study (SANSIKA) established the efficacy and safety of once-daily 0.1% cyclosporin A cationic emulsion (CsA CE) in severe keratitis due to dry eye disease (DED). This article presents results from the Post-SANSIKA study, a 24-month extension of SANSIKA assessing the sustained efficacy of CsA CE after treatment discontinuation.

The impact of pegylated interferon and ribavirin combination treatment on lipid metabolism and insulin resistance in chronic hepatitis C patients

Background/Aims

Lipid profile and insulin resistance (IR) are associated with hepatitis C virus (HCV) and may predict the chronic hepatitis C (CHC) treatment response. The aim of this study was to determine the association between CHC treatment response and lipid profile and IR change during treatment.

Methods

In total, 203 CHC patients were reviewed retrospectively between January 2005 and December 2011 at Soon Chun Hyang University Hospital. The lipid profile, homeostasis model for assessment (HOMA) of IR (HOMA-IR), and HOMA of β cells (HOMA-β) were evaluated before interferon plus ribavirin therapy (BTx), at the end of treatment (DTx), and 24 weeks after the end of treatment (ATx).

Results

A sustained virologic response (SVR) was achieved by 81% of all patients (49/60), 60% (n=36) of whom possessed genotype 1, with the remainder being non-genotype-1 (40%, n=24). Apart from age, which was significantly higher in the non-SVR group (SVR, 48.0±11.2 years, mean±SD; non-SVR, 56.6±9.9 years; P<0.01), there were no significant differences in the baseline characteristics between the SVR and non-SVR groups. In the SVR group, low density lipoprotein-cholesterol (LDL-C) had significantly changed at DTx and ATx compared to BTx. In addition, HOMA-IR and HOMA-β were significantly changed at DTx in the SVR group. Among those with a high baseline insulin resistance (HOMA-IR >2.5), HOMA-IR was significantly changed at DTx in the SVR group.

Conclusions

LDL-C appears to be associated with HCV treatment in SVR patients. Furthermore, eradication of HCV may improve whole-body IR and insulin hypersecretion, as well as high baseline insulin resistance (HOMA-IR >2.5).     

心肌脂质过氧化反应程度对糖尿病大鼠缺血再灌注损伤的影响

目的测定链脲佐菌素(STZ)诱导的不同周期精尿病大鼠对心肌缺血／再灌注(I／ R)损伤的影响及其与心肌脂质过氧化反应程度及血浆一氧化氮(NO)变化的关系。方法阻断和开放左冠状动脉前降支建立大鼠急性心肌I／R模型。用TTC染色测定大鼠心肌 I／R后梗死面积;用T／BARS法测定脂质过氧化反应程度;用硝酸还原酶法测定NO含量结果 STZ处理后2周,糠尿病组(2WD)心肌梗死面积比对照组(2WC)明显缩小,STZ处理后16周(16WD),梗死面积比对照组(16WC)增加;心脏组织的脂质过氧化物反应产物 2WD组较2WC组低,但是在16WD组中较16WC组显著增加;血浆NO水平2WD组较 2WC组增高,但是16WD组较16WC组显著减少。结论 STZ诱导的大鼠急、慢性期糖尿病对心肌I／R损伤呈现相反的作用。这可能是由于大鼠急、慢性期糖尿病相反的心肌脂质过氧化反应程度及NO改变而引起。
