Background:Defecation of patients with rectal carcinoma after operation cannot be controlled freely,which brings patients many mental burdens.Cocolyster operation can improve obviously the symptom.     

急性脑出血220例心电图分析

目的探讨脑出血急性期心电图异常的表现及特征。方法回顾分析220例住院各类急性脑出血患者的心电图资料,并分析其特点及与脑出血的关系。结果脑出血后继发心电图改变主要表现为ST-T改变和(或)心律失常。结论脑出血心电图异常与疾病的严重程度密切相关。心电图的异常可随脑血管病情的减轻而好转或消失,并对脑血管病情的预后有积极的意义。对高龄、高血压病等具缺血性心脏病的危险因素的人群,应加强监护。     

Acute pancreatitis in the aged

Forty-seven patients aged more than 75 years with acute pancreatitis were studied. The most common cause of acute pancreatitis was biliary tract stones. The clinical presentation and severity of the disease as judged by the number of poor prognostic factors were not different from the group of patients aged less than 75 years. The mortality rate in the older group was thrice that of the younger group (21.3% versus 7.24%). The higher mortality rate was explained by a higher incidence of deaths related to complications of biliary stones and coincidental diseases. Significantly more aged patients with mild disease died, indicating the limitation of predictive ability of the scoring system in acute pancreatitis of the aged.     

Influence of age on the mortality from acute pancreatitis

The influence of age on the mortality rate of 268 patients with acute pancreatitis was studied. The hospital mortality rate for patients aged below 50 years was 5.9 per cent. The figure increased to 21.3 per cent in patients aged over 75; the high mortality was accounted for by a higher incidence of deaths related to concomitant medical or surgical diseases in the same hospital admission rather than to complications resulting directly from the pathological process of acute pancreatitis. When only deaths due to complications of acute pancreatitis were analysed, the mortality rate was not significantly different between the young and elderly groups. Moreover, the complication rate and the proportion of patients having severe disease (judged by the number of prognostic signs) were not higher in the elderly. Thus acute pancreatitis was intrinsically not more serious were it not for the presence of concomitant diseases with advanced age.     

Sonographic appearance of Krukenberg tumor from gastric carcinoma

Sonographic findings in 16 cases of Krukenberg tumor from gastric carcinoma were analyzed. The patients' ages ranged from 25 to 52 years (mean 42 years). The tumor involved both ovaries in 14 patients with asymmetrical masses in 9 of 14 cases. Ascites was noted in 15 cases. Echogenicity of the tumor varied from solid to predominantly cystic: solid in 8, mixed in 6, and predominantly cystic in 2 cases. Solid masses tended to be smaller than mixed or cystic masses. The primary gastric carcinoma had been diagnosed before emergence of the tumors in only 7 cases. The findings suggest that in relatively young patients with ovarian mass, particularly bilateral tumors, careful evaluation for gastrointestinal tract involvement should be done.     

精神病混合家系GRIK2基因多态性的关联研究

目的　在中国汉族人群混合家系中探讨GRIK2基因多态性与精神分裂症、心境障碍是否 关联。方法　采用PCR RFLP技术对GRIK2基因多态性rs6922753(T/C)和rs2227283(G/A)分型,进行 传递不平衡检验(TDT)。结果　(1)rs6922753多态性与精神分裂症(χ2=3.13,P>0.05)或心境障碍 (χ2=3.20,P>0.05)无关联,但在发病年龄≤25岁的患者中与两组疾病均相关联(P<0.05);(2) rs2227283多态性与精神分裂症(χ2=9.85,P<0.01)、心境障碍(χ2=13.50,P<0.01)呈显著关联;(3) 双位点TDT提示单体型TG、CA与精神分裂症、心境障碍相关联(P<0.05)。结论　在中国汉族人群 中GRIK2基因或邻近基因可能是精神分裂症和心境障碍的共同易患基因之一,并可能影响发病年龄。     

中枢神经系统白血病血清神经元特异性烯醇酶测定的临床意义

目的 探讨血清神经元特异性烯醇酶与中枢神经系统白血病之间的关系。方法 对确诊的30例急性白血病患者及匹配的正常人的血清神经元特异性烯醇酶进行测定。结果 中枢神经系统白血病组血清神经元特异性烯醇酶含量21．92 7．5μg/L均明显高于白血病组、对照组，差异有显著性。结论 血清神经元特异性烯醇酶可作为反映中枢神经系统白血病病情的生化指标。     

INDICATIONS FOR ENDOSCOPIC MUCOSAL RESECTION FOR EARLY COLORECTAL CANCER: SHOULD THEY BE STRICT OR SHOULD THEY BE EXPANDED?

Endoscopic technologies have been developed greatly. As for early gastric cancer, the indications for endoscopic mucosal resection for early colorectal cancer have been widened recently. Technological advances can support wider and deeper resections using endoscopy but the remaining problem for the endoscopic management of cancer is lymph node metastasis. I discuss here the indication for endoscopic mucosal resection for early colorectal cancer to bring into focus the risk factors for metastasis to lymph nodes.
