The effect of a six-month exercise program on very low-density lipoprotein apolipoprotein B secretion in type 2 diabetes

The dyslipidemia and insulin resistance of type 2 diabetes can be improved by aerobic exercise. The effect of 6 months supervised exercise on very low-density lipoprotein (VLDL) apolipoprotein B metabolism was investigated in patients with type 2 diabetes. Moderately obese patients (n = 18) were randomized into supervised (n = 9) and unsupervised (n = 9) exercise groups. All patients were given a training session and a personal exercise program and asked to exercise four times per week at 70% maximal oxygen uptake for 6 months. Patients in the supervised group had a weekly session with an exercise trainer. VLDL apolipoprotein (apo)B metabolism was measured with an infusion of 1-(13)C leucine before and after 6 months of the exercise program. Supervised exercise for 6 months resulted in a significant within-group decrease in percent hemoglobin A1c (P < 0.001), body fat (P < 0.004), nonesterified fatty acid (P < 0.04), and triglycerides (P < 0.05) and an increase in insulin sensitivity (P < 0.01). There was a decrease in VLDL apoB pool size (160.8 +/- 42.6 to 84.9 +/- 23.2 mg, P < 0.01) and VLDL apoB secretion rate (11.3 +/- 2.6 to 5.5 +/- 2.0 mg/kg.d, P < 0.05) with no change in fractional catabolic rate. In a between-group comparison, the decrease in VLDL apoB secretion rate in the supervised group did not achieve significance. This study demonstrates that in type 2 diabetes, a supervised exercise program reduces VLDL apoB pool size, which may be due to a decrease in VLDL apoB secretion rate.     

超早期康复训练对急性脑卒中偏瘫患者运动功能及日常生活能力的影响

目的探讨超早期康复训练对脑卒中偏瘫患者肢体运动功能及日常生活能力(ADL)的治疗效果。方法入选2012年1月至2013年1月我院神经内科收治的急性脑卒中偏瘫患者164例,随机分为康复组(82例)和对照组(82例)。两组患者均常规药物治疗的同时,康复组超早期进行一对一康复训练,对照组未接受康复治疗,两组分别在病情稳定48 h后和治疗4周采用FugI-Meyer评定法对运动功能评分,用Barthel指数评分对日常生活能力评定。结果康复组的Fugl-Meye评分、Barthel指数评分均显著高于对照组(P<0.0001)。结论常规药物治疗加超早期康复训练对急性脑卒中偏瘫患者功能恢复有良好的促进作用。     

Fibromyxoma in the reticulo-omasal orifice of a cow

A 3-year-old female Holstein cow was referred for necropsy examination with the history of inappetence, progressive indigestion, distension of the rumen and death. At necropsy examination, a lobulated grey-white mass (12?×?8?×?5 cm) was found close to the reticulo-omasal orifice. On sectioning, the tumour mass was gelatinous with intervening fibrous septa. Microscopical examination revealed unencapsulated mass composed of various cellular parts and matrices. There were proliferated spindle shaped fibrocytes producing repetitive collagenous fibres. There were also foci of low cellularity containing stellate cells with small and hyperchromatic nuclei arranged in a mucinous ground substance. On the basis of the gross and histopathological findings and histochemical stainings, the tumour was diagnosed as a fibromyxoma. This tumour has not been recorded previously in the reticulo-omasal orifice of a cow.     

Sodium current and potassium transient outward current genes in Brugada syndrome: screening and bioinformatics

Background

Brugada syndrome (BrS) is a primary arrhythmia syndrome characterized by the occurrence of malignant ventricular arrhythmias. Previously, the genes SCN1B, SCN3B, MOG1, and KCND3 have been associated with BrS. Recent data from exome screening efforts permit better discrimination between low-frequency genetic variants and true monogenetic disease-causing variants. We aimed to screen the genes SCN1B through SCN4B, MOG1, CAV3, and KCND3 for variations in a population of SCN5A negative Danish and Iranian BrS patients, as well as research prior associations using newly released exome data.

Methods

Screening of all exons and splice sites was performed using Sanger sequencing. Bioinformatic searches were performed in the Single-nucleotide polymorphism database (build 132) and in the National Heart, Lung, and Blood Institute Grand Opportunity Exome Sequencing Project (ESP) for both previously published variant-BrS associations and newly uncovered variations within the noted genes.

Results

A total of 42 BrS patients were screened, and 2 different nonsynonymous mutations in SCN1Bb (H162P and R214Q) were found in 2 different Danish patients. The variants were not found in 216 Danish controls, but R214Q was present in ESP data (5 of 841 alleles). No other mutations were found. Previously BrS-associated mutations in KNCD3 and SCN3B were also present in ESP data. This was not the case for MOG1, but a nonsense polymorphism was present in 0.5% of alleles.

Conclusions

Our study supports the association of SCN1Bb with BrS. However, recently released exome data make some of the prior associations of BrS with genes SCN3B, MOG1, and KCND3 less likely.     

儿童外伤性胰腺炎13 例报告

目的：探讨儿童外伤性胰腺炎的临床特点及诊治方法。 方法：回顾性分析2003年1月—2011年12月收治的13例外伤性胰腺炎患儿的临床资料。 结果：13例患儿中,男8例,女5例;年龄5~12（7.22±3.54）岁。病因包括腹部钝挫伤7例,车祸伤4例,坠落伤2例,均为腹部闭合性损伤。9例胰腺I级损伤（2例合并肝挫伤）和3例II级损伤均采用抗感染、禁食、胃肠减压、全静脉营养,抑酶等保守治疗,其中4例出院1~2个月后并发胰腺假性囊肿,1例经对症治疗自行吸收,3例行囊肿空肠Roux-en-Y吻合术（其中1例腹腔镜下探查拟镜下吻合未成功中转开腹）;1例胰腺III级损伤（合并脾挫伤）行腹腔镜下腹腔引流术,术后1个月并发胰腺假性囊肿,行腹腔镜探查,囊肿空肠Roux-en-Y吻合术。所有患儿均治愈。 结论：儿童外伤性胰腺炎应根据胰腺损伤程度不同采取不同治疗方法。腹腔镜下腹腔引流术是治疗儿童III级外伤性胰腺炎的有效方法之一,但与腹腔镜下胰腺假性囊肿空肠吻合术一样仍需要进一步探索与总结。

A nonlinear quasi-static model of intracranial aneurysms

Abstract

Biomathematical modelsof intracranial aneurysms can provide qualitative and quantitative information on stagesof aneurysm development through elucidationof biophysical interactions and phenomena. However, most current aneurysm models, based on Laplace’s law, are renditionsof static, linearly elastic spheres. The primary goalof this study is to:1. develop a nonlinear constitutive quasi-static model and 2. derive an expression for the critical size/pressureof an aneurysm, with subsequent applications to clinical data. A constitutive modelof an aneurysm, based on experimental dataof tissue specimens available in the literature, was incorporated into a time-dependent setof equations describing the dynamic behaviorof a saccular aneurysm in response to pulsatile blood flow. The setof differential equations was solved numerically, yielding mathematical expressions for aneurysm radius and pressure. This model was applied to clinical data obtained from24 patients presenting with ruptured aneurysms. Aneurysm development and eventu.al rupture exhibited an inverse relationship between aneurysm size and blood pressure. In general, the model revealed that rupture becomes highly probable for an aneurysm diameter greater than 2.0mm and a systemic blood pressure greater than125 mmHg. However, an interesting observation was that the critical pressure demonstrated a minimal sensitivity to the critical radius, substantiating similar clinical and experimental observations that blood pressure was not correlated, to any degree, with aneurysm rupture. Undulations in the aneurysm wall, presented by irregularmultilobulated morphologies, could play an important role in aneurysm rupture. However, dueto the large variation in results, more extensive studies will be necessary for further evaluation and validationof this model.[Neural Res 1997; 19: 489-496]
