胃癌患者血清肝细胞生长因子的检测及意义

Objective To explore the clinical significance of serum HGF level changes in gastric cancer pa-tients. Methods 60 cases of patients who operatied and clinicopathological confirmed gastric cancer, were detected serum HGF level by enzyme linked immunosorbent assay(ELISA) .40 cases were administered radical gastrectomy,20 cases of patients who had distant metastasis and loss operative chance were detected 7 days and 3 months preopera-tive,postoperative serum HGF level respectively. At the same time 40 cases of chronic gastritis patients and 40 cases of healthy examination people were selected as control group. Results Serum HGF level in patients with gastric canc-er was significantly higher than that of chronic gastritis and normal controls(P <0. 01). The serum HGF level of pa-tients with tumor vascular invasion significantly increased(P <0. 05). The patients with lymph node metastasis,serum HGF level was significantly higher than that patients with no lymph node metastasis(P <0. 05). The serum HGF level of patients with liver metastasis was significantly higher than that patients with no liver metastasis(P <0. 05). The se-rum HGF level of gastric cancer patients whose maximum diameter of the tumor ≥3cm were significantly higher than that maximum diameter of the tumor <3cm(P<0. 05). According to TNM staging of gastric cancer,the serum HGF level of Ⅰ phase and Ⅱ phase patients were significantly lower than that Ⅲ phase and Ⅳ phase patients(P <0.05).The serum HGF level of gastric cancer patients had no significant correlation with sex ,age and histological type(P <0.05). The serum HGF level of 40 cases of patients who were 1 week after surgery were significantly decreased,the patients who were 3 months after surgery were more obvious(P <0. 05 and P <0. 001). Conclusion HGF may play an important role in gastric cancer occurrence and development. The detection of serum HGF level can become an im-portant index for monitoring the degree of gastric cancer and prognosis of patients.     

性病后非病原体性症状的临床分析

目的了解性病后非病原体性症状的性质特点。方法采用临床会谈、心理咨询、SCL—90、SAS、SOS等相关量表调查测评。结果纳入分析病人134例，首诊均作实验室检查培养，病原体检出率为零，体格检查无器质性病变，符合非病原体性症状诊断。结论此类“症状”实质上是患者因患性病导致心理障碍面出现的综合症，而“症状”并无器质性及病原体因素，医务人员应更新观念，提高自身素质解除患者心理障碍。

73例70岁以上妇女妇科恶性肿瘤手术分析

[目的]探讨70岁以上妇科恶性肿瘤患者手术的耐受情况。[方法]收集浙江省肿瘤医院自1996年1月到2001年12月间,70岁以上妇科恶性肿瘤患者接受盆腔姑息性和根治性手术治疗73例,分析不同年龄及手术范围对术后恢复的影响。[结果]73例患者66例选择了根治性手术,7例接受姑息性手术。术后70~75岁组和>75岁组,其手术方式、平均住院时间、术前术后并发症等无明显差别。术中出血量、手术时间及并发症发生率均明显较姑息性手术组增加,12例严重并发症中,11例发生在根治性手术组。[结论]经过严密的术前准备、术后处理,70岁以上的老年妇女能够耐受根治性手术治疗。     

EXPRESSION OF p16,CYCLIN D1 AND RB PROTEIN IN GASTRIC CARCINOMA AND PREMALIGNANT LESIONS

Gastric carcinoma is one of the most serious diseases in mankind. Its pathogenesis has not been understood very clearly. Recent researches suggested that oncogenes (such as cyclin D1), antioncogenes (ie., p16, Rb) and cell cycle played an important role in the pathogenesis of gastric carcinoma. But there are few reports about the relationship between these genes in gastric carcinoma and gastric premalignant lesions. In this study, we will discuss these problems. MATERIALS AND METHO…
