Primary epiploic appendicitis: an etiology of acute abdomen revealed by CT scan

Primary epiploic appendicitis are considered to be a rare cause of acute abdomen. We reported 2 cases in which computed tomography CT suggested the diagnosis. Primary epiploic appendicitis shows characteristic CT findings that allow the diagnosis and follow-up. This entity resolves spontaneously and CT helps in avoiding unnecessary surgery.     

Les bases scientifiques de la formation en médecine transfusionnelle

Transfusion medicine is a medical speciality which deals with all aspects of blood transfusion. The recent evolution of this speciality was marked by an increased collaboration with clinical medicine, the development of alternatives to allotransfusion (autotransfusion, growth factors, molecular genetics), and the technical progress in laboratory techniques. The development of basic science boosted the introduction of new techniques in the detection of virus and blood cell typing. The analysis of clinical trials allowed a better definition of guidelines for the use of blood products. The blood transfusion teaching program is limited during medical training. Specialists in transfusion medicine have to complete a post-graduate course to become certified. Continuous medical training is organised to allow the specialists to keep their accreditation. Transfusion medicine is becoming more and more complex. This complexity should not lead to breaking down transfusion medicine into several activities, but on the contrary to uniting this medical speciality, within which the different actors shall remain open-minded and able to use the same 'language'.     

延续护理对永久人工心脏起搏器植入术患者自我护理能力与生活质量的影响

目的探讨延续护理干预对永久人工心脏起搏器植入术后患者自我护理能力与生活质量的影响。方法选取永久人工心脏起搏器植入患者60例为研究对象,根据入院时间先后顺序不同随机分为观察组32例和对照组28例。对照组患者接受传统护理干预,观察组患者出院后接受延续性护理干预,比较2组患者自我护理能力、生活质量、不良反应等。结果干预后,观察组患者的躯体健康、心理健康、社会功能、物质条件评分显著高于对照组患者(P0.05);干预后,观察组患者的遵医行为显著优于对照组患者(P0.05);出院后6个月,观察组自我概念、自护责任感、健康知识水平、自我护理技能显著优于对照组(P0.05)。结论永久人工心脏起搏器植入患者在出院后接受延续性护理干预,可以有效提升患者出院后生活质量。     

辽宁省精神卫生服务质量现状调查

目的：调查了解辽宁省精神卫生服务现状。方法：通过普查的方法对辽宁省28所非独立精神卫生服务机构和44所独立精神卫生服务机构进行精神卫生服务质量现状调查。结果：独立与非独立精神卫生机构在卫生服务质量方面存在差异。结论：我省精神卫生资源不足,在现有条件下还存在精神卫生资源利用效率低下的问题。     

Computer characterization of sinus rhythm.

Sinus rhythm tracings, including sinus tachycardia and bradycardia, are characterized quantitatively by means of an ECG measurement program which has been subjected to rigorous evaluation. The analysis is performed on tracings of short duration (10 sec). The features of regularity and stability are considered for the R wavetrain. Regularity is evaluated from the normalized differences between sucessive RR intervals. Stability is determined by the ratio of maximum and minimum RR interval durations. Due to the difficulities of automatic beat-to-beat detection and measurement of P waves, an estimate of the PR interval is obtained from a pseudo-PR interval determined from certain features of the P and R wavetrains. The constancy of this pseudo-PR interval is evaluated, and its absolute value is uded as a characteristic of the type of sinus rhythm.     

Relationship between lipogenesis,ketogenesis, and malonyl-CoA content in isolated hepatocytes from the obese Zucker rat adapted to a high-fat diet

The relationship between lipogenesis and ketogenesis and the concentration of malonyl coenzyme A (CoA) was investigated in hepatocytes from adult obese Zucker rats and their lean littermates fed either a control low-fat diet or a high-fat diet (30% lard in weight). With the control diet, lipogenesis—although strongly inhibited in the presence of either 1 mmol/L oleate, 10^?6 mol/L glucagon or 0.1 mmol/L TOFA (a hypolipidemic drug)—remained about fifteen-fold higher in the obese rats than in the lean rats. In contrast, ketogenesis under some conditions (oleate + TOFA) was not significantly lower (30%) as compared with the lean rats. After adaptation to the high-fat diet, lipogenesis was depressed fourfold in the lean rats and ninefold in the obese ones; however its magnitude remained significantly higher in the latter, namely at a value close to that measured in control-fed lean rats. Ketogenesis was comparable in lean and obese rats and much higher in the presence of 1 mmol/L oleate than of 0.3 mmol/L oleate, whereas lipogenesis did not vary with increasing oleate concentration in the medium. Acetyl-CoA carboxylase activity measured in liver homogenates was higher in the obese group, but was stepwise inhibited by increasing concentrations of oleyl-CoA regardless of the diet for both lean and obese rats, thus showing no abnormality of in vitro responsiveness to this inhibitor. With the control diet, hepatocyte malonyl-CoA levels were significantly higher in the obese rats, both in the basal state and after inhibition of lipogenesis by oleate and TOFA. However, after the high-fat diet, there was no longer a significant difference between the genotypes. These results show that in the obese Zucker rats, ketogenesis is dependent on hepatocyte malonyl-CoA content in the sense that their ketogenic capacity becomes “normalized” when malonyl-CoA is decreased to the levels found in the lean littermates, as it is the case after fat-feeding. This normalization of malonyl-CoA levels in spite of higher lipogenesis in the obese rats may result from the activities of enzymes of its formation and utilization.
