Sesame Oil Therapeutically Ameliorates Cardiac Hypertrophy by Regulating Hypokalemia in Hypertensive Rats

Background: Hypokalemia and hypertension are common manifestations of preclinical cardiovascular conditions that have a predictive value for cardiovascular morbidity and mortality. Cardiac hypertrophy, an important risk factor in heart failure, is attributed to long‐term hypokalemia and hypertension. Sesame oil is rich in nutrients and possesses potent antihypertensive activities. Methods: We investigated the therapeutic potential of sesame oil using a hypertensive model created by subcutaneously injecting deoxycorticosterone acetate (DOCA; 15 mg/mL/kg in mineral oil; twice weekly for 5 weeks) and supplementing with 1% sodium chloride drinking water (DOCA/salt) to uninephrectomized rats. Sesame oil was administered by oral gavage (0.5 or 1 mL/kg/d for 7 days) after 4 weeks of DOCA/salt treatment. Systolic blood pressure (SBP) and diastolic blood pressure (DBP), electrocardiography (ECG), and K⁺ and Mg²⁺ levels were assessed 24 hours after the last dose of sesame oil. Heart tissue was collected for histologic analysis. Results: Sesame oil effectively reduced the SBP/DBP and ECG abnormalities and increased the serum levels of K⁺ and Mg²⁺ while limiting the urinary excretion of K⁺ in DOCA/salt‐induced hypertensive rats. In addition, sesame oil decreased the heart mass, the thickness of the left ventricle, and the diameter of cardiomyocytes, indicating the regression of left ventricular hypertrophy in the hypertensive rats. Conclusion: We demonstrate that sesame oil therapeutically ameliorates cardiac hypertrophy by regulating hypokalemia in hypertensive rats.     

颈动脉硬化的磁共振血管成像技术分析

目的 分析磁共振血管成像显示颈动脉硬化的表现、技术。方法 对50例病人进行对比增强磁共振血管造影(CE-MRA)检查,部分同时接受颈动脉非增强磁共振血管造影(2D-TOF-MRA)检查,研究影像表现。结果 CE-MRA排除了4支在2D-TOF-MRA上显示为狭窄的颈动脉,对9支2D-TDF-MRA显示为正常的颈动脉诊断为轻度狭窄,另外发现了2处在2D-TOF-MRA上由于超出了扫描视野而未被显示的狭窄颈动脉。结论 MRA是能够精确显示颈动脉的非侵人性检查方法。CE-MRA显示血管狭窄较2D-TOF敏感和准确,能够提供更为满意的血管形态学资料。     

弓形体病12例临床分析

报道弓形体病12例，其中，男女各6例，以20－30岁者为多，农民和农村学生占7例。主要症状是发热，乏力，头昏，畏寒，腹胀和纳差；主要体征有肝，脾，淋巴结肿大和下肢出血点。根据临床表现和血清免疫学检查阳性而确诊。以螺旋霉素和复方新诺明联合治疗，7天为一疗程，1－4个疗程后，11例好转或痊愈，1例死亡。有免疫缺陷或免疫务受损者以及胎儿易感染本病。急性感染的后果取决于宿主的免疫状态。     

针式腹腔镜下胆囊切除术的临床应用

目的 与开腹胆囊切除术相比,腹腔镜胆囊切除术（ＬＣ）有减少术后不适和较少的创作,但仍有改进的余地。方法：为进一步减轻手术创伤,我们引进了针式腹间胆囊切除术,共２９例。结果 平均手术时间为７５分钟,１９例当天出院,１０例隔天出院,其中１例是胆总管探查。结论 针式航空 镜胆囊切除术是一种可靠的技术。
