C反应蛋白监测在急性胰腺炎中的诊断和预后价值分析

目的:探讨C反应蛋白监测在急性胰腺炎中的诊断和预后价值.方法:急性胰腺炎32例、急腹症32例及健康人32例,在第1、4、7天同时监测C-反应蛋白含量.结果:与对照组比较,急性胰腺炎患者第1天血清中的C-反应蛋白即明显升高,在第4天达到高峰,到第7天时降到第1天之下,各组间比较均有统计学差异(P<0.05).急腹症患者在第1天、第4天、第7天血清中的C-反应蛋白含量与对照组比较,均有统计学差异(P<0.05).第1天血清中的C-反应蛋白即开始升高,在第4天逐渐下降,两天的含量比较有计学差异(P<0.05),之后又逐渐下降,到第7天时降到第4天之下,比较也有统计学差异(P<0.05).这表明,CRP对急性胰腺炎是否发生感染可能有一定的预测和鉴别价值.CRP半衰期短于24h,故一旦感染,CRP立即升高,感染越严重,其浓度越高,而一旦感染得到控制,血清CRP又会迅速下降.结论:目前CRP已作为临床上的监测常规,成为预测急性疾病严重性的金标准,其在急性胰腺炎早期明显升高,与病情的严重程度成明显正相关.检测血清CRP水平对急性胰腺炎早期诊断及严重程度预测有重要价值,并为临床急性胰腺炎的治疗提供一定的依据.

Results of treatment of cancer of the cardia

Cancer of the cardia is traditionally discussed with cardiac cancer of the lower portion of the esophagus and upper gastric cancer invading the esophagus, and the specific characteristics of cancer of the cardia have never been clearly defined. We reviewed the outcome of 172 patients with adenocarcinoma of the cardia who had undergone radical surgery between 1949 and 1994 in the Division of Gastrointestinal Surgery of the Cancer Institute Hospital. The centers of the tumors were located within 2 cm above and below the boundary between the esophagus and the stomach, and their longitudinal diameter was less than 8 cm. We divided the patients into an early period (1949-1979; n = 79) and a late period (1980-1994; n = 93), and focused on the historical transition. There were no differences in patient gender or histology between the two periods. However, the late period was associated with fewer cases of esophageal invasion and shorter longitudinal diameter, as the age of the population advanced. The number of advanced cancers such as the localized and infiltrative type had decreased, and early cancer and early clinical stage had become more common, but despite the fact that the number of early cancers had increased, extended dissection, such as thoracic and paraaortic lymph node dissection, was performed more frequently. By clinical stage, the long-term outcome markedly improved in Stage I patient in the late period, and tended to improve in Stage II and III patients. This appears to have been attributable to the prevention of micrometastasis by extended dissection, although the number of early cancers is another major potential cause. There were no differences in the outcome of Stage IV patients between the two periods, and further advances in multimodality therapy must be awaited. The range of resection is basically proximal gastrectomy, and if there are adequate indications, the prognosis is favorable. In view of the status of lymphatic flow and lymph node metastasis, and long-term results, lateroaortic lymph node dissection is important. Since the number of early cancer patients has been increasing, if intraabdominal recurrence is prevented, intrathoracic lymph node dissection will contribute greatly to the outcome of such patients.     

The effect of amount of possession of the trait of hostility on accuracy of perception of hostility in others.

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

Comparison of rates of infection of two methods of emergency ventricular drainage

The rates of infection of two methods of external ventricular drainage in use at Atkinson Morley's Hospital--namely, (a) percutaneous drainage with Rickham reservoirs and (b) tunnelled ventriculostomies--were compared in this retrospective review. Percutaneous drainage of CSF with Rickham reservoirs was associated with a 27% rate of infection as identified by positive microbiological cultures; tunnelled ventriculostomy catheters had a 10% infection rate. The difference in the infection rate between the two methods was statistically significant (P < 0.015). Other variables examined, including the age and sex of the patients and the reasons for ventricular drainage, were not associated with an increased rate of infection. Most infections from either method were caused by a coagulase negative staphylococcus. The average duration of ventricular drainage before identification of positive cultures was 5.7 days for Rickham reservoirs and 6.0 days for ventriculostomies.
