锁骨下动脉损伤及创伤性假性动脉瘤手术方法探讨

目的探讨锁骨下动脉损伤及创伤性动脉瘤的外科治疗方略。方法1991—2005年对2例锁骨下动脉损伤，6例锁骨下假性动脉瘤根据病变的部位、程度及受伤时间、累及范围等选择手术入路，采用血管缝扎、血管壁修补、血管吻合、血管移植、辅助体外循环及球囊止血技术实施手术。结果6例痊愈，1例动静脉狭窄，1例动脉闭塞伴臂丛损伤。平均失血800mL。结论锁骨下动脉损伤及假性动脉瘤手术复杂，术前对病变进行仔细评估，选择合理的切口及手术方法是减少并发症的关键。     

Multiclefted nuclei. A helpful feature for identification of intermediate trophoblastic cells in uterine curetting specimens.

Intermediate trophoblast is a distinct form of trophoblast, the presence of which in uterine curettings is considered a reliable indicator of intrauterine pregnancy even in the absence of chorionic villi. However, the appearance of intermediate trophoblastic cells have not been described in sufficiently specific terms to permit their reliable identification, and distinction from decidual cells can be difficult. We have noticed for some time that the intermediate trophoblastic cells often show multiple deep clefts in the nuclei, and the present study was performed to address the issue of whether this nuclear feature is reliable for their identification. We reviewed 242 uterine curettings of intrauterine pregnancy, documented by the presence of chorionic villi, and were able to find a distinct population of cells with large, hyperchromatic, multiclefted nuclei scattered in the decidua in 88% of the cases. In most instances, these cells produced a characteristic variegated pattern that was readily recognizable at low magnification. Positive immunostaining for cytokeratin (CAM 5.2) in these isolated cells within the decidua confirmed their trophoblastic nature. In contrast, multiclefted nuclei were absent in the 51 negative control cases, which included decidualized endocervical polyps (40 cases), uterine curettings from patients with tubal pregnancy (10 cases), and endometriosis with decidual change (one case). We conclude that intermediate trophoblastic cells can usually be reliably identified in curettings of intrauterine pregnancy by their characteristic nuclear multiclefting.     

Variation of Apolipoprotein A-I in Cirrhosis and its Clinical Value

The serum apolipoprotein A- I (apo A-I) Concentrations in 39 patients with posthepatitis cirrhosis were reported to be 0.87±0.27 g/L lower than that of controls 1.15±0.14 g/L P<0.01. The, decrease of apo. A-I was correlated with the severityof impaired liver function. Apo A- I concentrations in serum correlated positively with decrease of serum albumin (r=0.503 P< 0.01) and negatively with serum bilirubin increase (r=- 0.508 P <0.01) . The data indicate that decreasing of apo A- I concentration may be regarded as one of the reliable indices reflecting the degree of liver function impairment.
