新生儿溶血病D-二聚体变化的临床研究

目的探讨新生儿溶血病D-二聚体水平变化及临床意义。方法选取新生儿溶血病患儿60例,按照胆红素水平分为非重度组（34例）和重度组（26例）。同期出生的40例正常足月儿为对照组。检测各组D-二聚体及纤维蛋白原(FIB)水平的变化。结果重度组、非重度组D-二聚体水平[分别为(9.29±11.34)、(0.84±0.77) mg/L]明显高于对照组[(0.45±0.06) mg/L](P＜ 0.01或＜0.05),重度组明显高于非重度组(P＜0.01)。各组FIB水平比较差异无统计学意义(P＞0.05)。结论重度新生儿溶血病患儿体内存在高凝状态,血浆D-二聚体水平测定对新生儿溶血病患儿的病情判断和治疗有一定的价值。     

提高大鼠心肌梗死后心力衰竭模型存活率的实验研究

目的建立大鼠心肌梗死后心力衰竭模型,并进行评估,以提高存活率和成功率。方法分批对70只SD大鼠行冠状动脉左前降支结扎术,同时设15只假手术组,并计算死亡率。于4周时行血流动力学检查,检测心率(HR)、左心室舒张末压(LVEDP)、左室压力最大上升速率(+dp/dtmax)以及左室压力最大下降速率(-dp/dtmax)。结果4周时模型组HR、+dp/dtmax和-dp/dtmax绝对值均低于假手术组(P<0.05),LVEDP则高于假手术组(P<0.05)。随着手术大鼠例数增多,存活率得到提高(P<0.05)。结论心肌梗死后4周形成心力衰竭模型,通过经口气管插管法、选择结扎冠状动脉分支末梢部位、增加手术操作熟练程度,可提高动物存活率。

Mineral Status of Myocardial Sarcocystosis

Background

The role of minerals on parasite persistency and the interaction between minerals and animal responses to the parasite infestation is not clear. For these reasons, the present research was aimed to compare copper, zinc and iron status in sheep with parasitic myocarditis and healthy ones in 2009.

Methods

Blood and heart tissue samples were collected from 145 slaughtered sheep and histopathological findings were confirmed as myocardial sarcocystosis in 27 cases. Serum and tissue mineral level were determined by atomic absorption spectroscopy. Data were analyzed by Sigmastat program, using One Way Analysis of Variance (ANOVA) at the level of P<0.05.

Results

Myocardial sarcocystosis significantly increase myocardial concentration of Cu, Zn and Fe (P<0.05).

Conclusion

These findings may explain the role of copper, zinc and iron in parasite persistency and may discuss the pathogenesis of sarcocystosis, which relates to evocate mentioned micronutrient to cardiac muscle.     

脑利钠肽与超声心动图在川崎病诊断中的意义

目的探讨脑利钠肽(brain natriuretic peptide,BNP)与超声心动图在川崎病急性期及恢复期诊断中的临床意义。方法选取川崎病患儿35例为病例组,以发热、皮疹为主诉的肺炎支原体或病毒感染的48例患儿为对照组,测其急性期与恢复期脑利钠肽及左、右冠状动脉内径值,并做相关分析。结果川崎病患儿急性期脑利钠肽值明显高于恢复期,且差异有统计学意义;川崎病患儿恢复期冠状动脉内径值明显高于急性期,且差异有统计学意义。结论应用超声心动图检测冠状动脉扩张是在恢复期诊断川崎病的重要手段,而脑利钠肽可作为急性期诊断川崎病的生化指标之一。     

污水中汞的微波消解冷原子吸收测定法

Parathyroid adenomas evaluated by Tl-201/Tc-99m pertechnetate subtraction scintigraphy and high-resolution ultrasonography

Thallium-201/technetium-99m pertechnetate subtraction scintigraphy of the parathyroid glands was performed in a prospective study of 33 patients who had undergone bilateral neck exploration for elevated serum calcium and serum parathyroid hormone levels. In 31 cases, the Tl-201/Tc-99m subtraction technique yielded an overall sensitivity of 81%, specificity of 99%, and accuracy of 94% for identifying solitary parathyroid adenomas. Tl-201/Tc-99m subtraction scintigraphy correctly identified 73% of parathyroid adenomas weighing less than 499 mg, 79% of those weighing 500-1,499 mg, and 100% of adenomas weighing more than 1,500 mg. In a subgroup of 24 patients with solitary parathyroid adenomas who underwent both scintigraphy and high-resolution sonography, the sensitivity, specificity, and accuracy of both procedures were similar.     

Thoracic wall involvement by Hodgkin disease and non-Hodgkin lymphoma: CT evaluation

Thoracic computed tomographic (CT) scans of 250 patients with newly diagnosed or recurrent lymphoma revealed thoracic wall involvement in 24 patients (11 with Hodgkin disease, 13 with non-Hodgkin lymphoma). Thoracic wall involvement occurred without contiguous mediastinal or parenchymal involvement in 17 patients. Of these, 13 patients had masses beneath the pectoralis muscles or within the breast, and four had masses arising from the ribs. Five additional patients had mediastinal masses with thymic involvement and parasternal extension through the thoracic wall. Pulmonary parenchymal lymphoma with thoracic wall invasion was noted in the remaining two patients. In five of nine patients receiving radiation therapy, treatment plans were modified by CT demonstration of thoracic wall lymphoma.

Peptic ulcer and gastric carcinoma: diagnosis with biphasic radiography compared with fiberoptic endoscopy

The diagnostic value of biphasic radiographic examination of the stomach and duodenum was compared with that of fiberoptic endoscopy in a prospective, blinded study of 385 patients with dyspepsia. This investigation was directed at gastric malignancies and peptic ulcers. Methodologically there is no absolute standard for a study of this kind because histologic examination is useful for detection of cancer but inadequate for ulcers. As an alternative, kappa indexes and the sensitivity and specificity, as derived by Hui and Walter, were calculated and compared. For the detection of gastric carcinoma, radiographic and endoscopic findings had almost perfect agreement beyond chance. For gastric ulcers, radiography and endoscopy had substantial agreement, which became perfect if small ulcers (less than 5 mm) were excluded. For duodenal ulcers, radiography had a lower sensitivity than endoscopy; this disagreement disappeared if small ulcers were excluded. Both methods have equal merit; choice of the initial diagnostic procedure will therefore depend on cost, discomfort to the patient, and risk of complications.
