Abdominal Obesity Associated with Elevated Serum Butyrylcholinesterase Activity,Insulin Resistance and Reduced High Density Lipoprotein-Cholesterol Levels

Abdominal obesity (AO) has a strong correlation with cardiovascular disease and has been linked to Alzheimer’s disease and type 2 diabetes. We investigated the association between AO and elevated serum butyrylcholinesterase (BChE) activity, insulin resistance and the serum lipid profile, including triglyceride (TG), HDL-cholesterol (HDL-C) and LDL-cholesterol (LDL-C) levels in AO and non-AO women subjects. A total of 500 AO subjects (age 49.1 ± 10.5 years), and 142 non-AO women subjects (age 49.9 ± 11.9 years) were enrolled for the general biochemistry tests, serum BChE, fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR). Body mass index, waist circumference, Blood pressure (BP), plasma glucose (Glu), triglyceride (TG), BChE, insulin, HOMA-IR were significantly higher and HDL-C levels were significantly lower in AO subjects (p < 0.05). Waist circumference was significantly correlated with BP, Glu, TG, BChE, insulin and HOMA-IR in AO subjects. Multiple logistic regression demonstrated that AO was associated with elevated BChE, HOMA-IR, hypertension and reduced HDL-C after adjusting for these variables. AO is associated with elevated BChE, insulin resistance, HT and reduced HDL-C. These may predict the development of type 2 diabetes mellitus and may be associated with cognitive disorder in the future, both are mediated through insulin resistance.     

豚鼠主动脉前庭组织自律性的电生理学和形态学研究

利用细胞内微电极技术和组织学技术,对82只琢鼠主动脉前庭的自发电活动和13例该部组织的形态学特征进行了观察和分析。结果发现,在82例该组织的游离标本上,有16例(19.5％)可自行出现自律性电活动;61例(74.4％)在电刺激诱导下也可出现自律性电活动。在主动脉前庭大部分区域记录到的自发电位,其形态与普通心室肌的动作电位基本相同,属快反应电位。而在主动脉瓣右瓣与后瓣交界处以下约2.0×1.5mm区域内的表疲疲部位,可记录到0相去极化缓慢、幅值较小,且4相自动去极化明显的动作电位,其形态与慢反应自律细胞的动作电位十位相似。肾上腺素可使其频率增快;钙拮抗剂硝苯吡啶、Mn~(2十)可阻断其自律性电活动。而且上述大部分区它归快反应电位随此慢反应电位的节律而变化,并随其被阻断而消失。说明在主动脉前庭的局部存在有慢反应自律细胞,其的部位的自发节律系由该部引起。经光镜和电镜观察,该部组织与普通心肌有明显不同,而与慢反应自律组织的结构相似。本实验提示:在发生上由动脉球变化而来的主动脉前庭部组织,先保持有自律性等与普通心室肌不同的电生理特征。因而在心脏泵血过程中,可能具有某些特殊功能。     

Three Cases of Lead Toxicity Associated with Consumption of Ayurvedic Medicines

Ayurveda is a traditional form of medicine used by majority of the Indians. Here we report three cases of lead toxicity, following intake of Ayurvedic medicines. Three patients presented with blood lead levels (BLLs) of 122.4, 115 and 42.8 μg/dl respectively at the time of hospitalization. The first case was chelated with D- penicillamine, the second with calcium disodium ethylene diamino tetra acetate (EDTA) and the third with environmental intervention and education. Associated Ayurvedic products were collected from patients and analyzed for metallic concentration. Cessation of Ayurvedic medication along with chelation, nutritional intervention and education, reduced the BLL to 27.4 μg/dl in the first case after 1 year, 21.1 μg/dl after 9 months in the second and 18.2 μg/dl after 6 months in the third case.     

Cs对家兔窦房结和主动脉前庭的电生理效应

目的 :探讨CsCl对心脏慢反应自律细胞的电生理效应。方法 :应用细胞内微电极记录技术 ,观察了 16例家兔窦房结和主动脉前庭 (左心室流出道 )自律细胞动作电位的特征。以分析CsCl对窦房结和流出道自律细胞作用的异同。结果 :给予 2mmol/LCsCl灌流后 ,两自律细胞自发慢反应电位的VDD及RPF均明显减慢 (P <0 .0 5 ) ,10min左右达到最大效应 ,而MDP、APA、Vmax、APD、APD50 、APD90 与正常对照比均无明显差别 (P >0 .0 5 )。结论 :CsCl对窦房结起搏细胞和主动脉前庭自律细胞的起搏离子流有明显抑制作用。     

Lead toxicity as a result of herbal medication

Awareness about the toxic effects of non-essential metals is still lacking in developing countries. Lead is one among them, which ranks second in the Agency for Toxic Substances and Disease Registry’ s top 20 lists of toxic metals. Some of the herbal medicines prepared from certain roots and leaves are known to contain this toxic metal at alarming levels. We have a case of a person who suffered from the toxic effects of lead such as vomiting and colicky abdominal pain after consuming a herbal remedy for Jaundice treatment. This went unrecognized initially because of the presence of multiple problems like Malaria and Renal calculi. Lead poisoning as causative factor for anemia, vomiting and colic were confirmed only when blood lead concentration was estimated. A combination of chelation therapy and nutritional supplementation was found to be useful in reducing the body lead burden.

显微手术治疗颅内多发动脉瘤

对47例经造影及手术证实的颅内多发动脉瘤进行显微手术治疗。术后恢复工作42例,轻残2例,重残1例,死亡2例。结果表明,术前识别破裂动脉瘤和术中先处理破裂动脉瘤十分重要。尽可能一期手术处理完所有多发动脉瘤,对于不能一期手术的多发动脉瘤,应先期处理破裂动脉瘤,然后二期手术处理未破裂动脉瘤。血管造影为单发动脉瘤,而术中所见与CT和造影的部位不相符时,应想到多发动脉瘤之可能。     

Complex pathologies of angiotensin II-induced abdominal aortic aneurysms

Angiotensin II (AngII) is the primary bioactive peptide of the renin angiotensin system that plays a critical role in many cardiovascular diseases. Subcutaneous infusion of AngII into mice induces the development of abdominal aortic aneurysms (AAAs). Like human AAAs, AngII-induced AAA tissues exhibit progressive changes and considerable heterogeneity. This complex pathology provides an impediment to the quantification of aneurysmal tissue composition by biochemical and immunostaining techniques. Therefore, while the mouse model of AngII-induced AAAs provides a salutary approach to studying the mechanisms of the evolution of AAAs in humans, meaningful interpretation of mechanisms requires consideration of the heterogeneous nature of the diseased tissue.
