场依存-独立性认知方式与儿童自立水平的关系

目的:探讨场依存一独立性认知方式与儿童自立发展水平之间的关系.方法:①应用6-12岁儿童自立行为问卷对120名4-6年级小学生进行评定,根据儿童在自立行为问卷上的总分排序,取上27％人群高自立组,下27％人群为低自立组;②被试的认知方式是依据其在该年级组的镶嵌图形测验平均成绩确定的,将测验总分排序位于上25％的30名儿童确定为场独立性被试,测验总分排序位于下25％的30名儿童确定为场依存性被试.结果:①高自立组认知方式得分显著高于低自立组,场独立认知倾向组在自立行为问卷的学业自立和自我决断分量表上的得分显著高于场依存认知倾向组;②认知方式得分与自立行为问卷的学业自立、日常自立、自我决断、自我行动、自我负责以及自立总分呈显著正相关.结论:自立行为水平与儿童的认知方式特点密切相关.与低自立水平儿童相比,高自立水平儿童的认知方式更倾向于场独立性,场独立性倾向者自立水平较高而场依存性倾向者自立水平较低.

Clinicopathologic features and survival of patients with colorectal mucinous, signet-ring cell or non-mucinous adenocarcinoma:experience at an institution in southern China

Background Previous studies have shown conflicting results on the relation between clinicopathologic features and prognosis of patients with colorectal mucinous, signet-ring cell, or non-mucinous adenocarcinoma; only few such studies have been performed in China. This retrospective study analyzed data from our department to investigate clinicopathologic characteristics, prognosis and possible correlations of three histologic types -- colorectal mucinous,signet-ring cell, and non-mucinous adenocarcinoma, to clarity the bases for observed differences which may lead to development of targeted therapies Methods Of 2079 patients diagnosed with colorectal cancer between 1994 and 2007, 144 had mucinous, 25 had signet-ring cell, and 1837 had non-mucinous adenocarcinoma. Their clinicopathologic parameters and survival were analyzed using established statistical methodologies.Results Mucinous and signet-ring cell adenocarcinomas were common in younger patients (P <0.001). Location, size and disease stage differed significantly among the three types. Signet-ring cell tumors were more commonly found in the rectum than mucinous and non-mucinous adenocarcinoma (P <0.001). Mucinous and signet-ring cell tumors presented in a later stage in life more often than non-mucinous adenocarcinoma, with lymph node involvement, serosal infiltration, peritoneal dissemination, and adjacent organ invasion (P <0.01). The rate of radical resection, hepatic metastasis and local recurrence did not differ among types (P ＞0.05). Compared with patients with non-mucinous adenocarcinoma, patients with mucinous and signet-ring cell tumors who underwent potentially curative resections or stage Ⅱ/Ⅲ disease had poorer long-term overall survival. Survival did not differ by type for patients with either stage Ⅰor Ⅳ disease (P ＞0.05). Conclusions Mucinous and signet-ring cell adenocarcinoma have unique carcinogenesis and similar biologic behavior.Our study confirms that both histologic types, especially signet-ring cell tumors, are independent, negative prognostic factors for patients with colorectal cancer. Type does not appear to have a significant effect on survival when disease is either stage Ⅰ or Ⅳ at presentation.     

Early operation for fulminant acute pancreatitis: a possible way to decrease mortality

Background Although the indication and the timing for surgery in fulminant acute pancreatitis (FAP) are still controversial, our experience of surgical treatment for fulminant acute pancreaUtis may help improve the outcome for patients.Methods The clinical data of twenty-six patients with FAP from January 1, 2001 to October 1,2005 were analyzed. The diagnostic criteria fitted the 2007 Guidelines for the Management of Severe Acute Pancreatitis by the Chinese Medical Association.Results Twenty-six patients with FAP received surgical debridement, with a mortality rate of 42.3% (11/26). The postoperative mortalities in the ＞72 hour operation group and the <72 hour operation group were highly significantly different (7/8 vs 22.2% (4/18), respectively).Conclusions Early surgery may reduce the intraabdominal pressure and prevent the deterioration of FAP. An operation within 72 hours from the onset of symptoms might decrease the mortality of the disease.
