目的探讨不同类型肾脏占位病变的超声造影特点。方法对照病理诊断结果分析76例肾脏占位病变Sono Vue超声造影特征。结果肾恶性肿瘤62例,良性肿瘤14例。肾恶性肿瘤超声造影剂的充盈和消退呈多样性,以同步增强和快增强多见,造影剂的快速消退和缓慢消退之间无明显差别,差异无统计学意义(P>0.05)。恶性肿瘤典型的表现是整个病灶弥漫增强,轮廓边界清晰,呈"亮球"征(95.2%),并多有假包膜(87.1%)。肾错构瘤表现为无假包膜的不均匀增强,而肾囊肿始终无增强。结论超声造影有助于肾占位病变的鉴别诊断和预后判断。  相似文献

This systematic review examines critically the scientific basis for Canada's Physical Activity Guide for Healthy Active Living for adults. Particular reference is given to the dose-response relationship between physical activity and premature all-cause mortality and seven chronic diseases (cardiovascular disease, stroke, hypertension, colon cancer, breast cancer, type 2 diabetes (diabetes mellitus) and osteoporosis). The strength of the relationship between physical activity and specific health outcomes is evaluated critically. Literature was obtained through searching electronic databases (e.g., MEDLINE, EMBASE), cross-referencing, and through the authors' knowledge of the area. For inclusion in our systematic review articles must have at least 3 levels of physical activity and the concomitant risk for each chronic disease. The quality of included studies was appraised using a modified Downs and Black tool. Through this search we identified a total of 254 articles that met the eligibility criteria related to premature all-cause mortality (N = 70), cardiovascular disease (N = 49), stroke (N = 25), hypertension (N = 12), colon cancer (N = 33), breast cancer (N = 43), type 2 diabetes (N = 20), and osteoporosis (N = 2). Overall, the current literature supports clearly the dose-response relationship between physical activity and the seven chronic conditions identified. Moreover, higher levels of physical activity reduce the risk for premature all-cause mortality. The current Canadian guidelines appear to be appropriate to reduce the risk for the seven chronic conditions identified above and all-cause mortality.  相似文献

摘要:目的 探讨新疆乌鲁木齐市维吾尔族人群成人支气管哮喘的影响因素。方法 本研究采用成组匹配病例对照研究方法,病例组为新疆医科大学第一附属医院呼吸内科在2014年1-12月确诊的维吾尔族支气管哮喘成人患者(n=120例),对照组为同期体检中心健康维吾尔族体检者(n=126例),两组在年龄、性别相匹配。采用问卷调查的方法收集相关暴露资料,并采用单因素分析及多因素非条件Logistic回归模型分析成人支气管哮喘影响因素。结果 多因素Logistic回归分析显示,吸烟(OR=1.88,95% CI:1.28~2.96)、家族支气管哮喘史(OR=6.20,95% CI:2.10~18.31)、家中铺有纯毛地毯数量多(OR=1.87,95% CI:1.18~2.95),睡眠质量(OR=1.46,95% CI:1.22~1.75),患慢性支气管炎(OR=13.43,95% CI:6.65~25.34)及过敏性鼻炎(OR=6.27,95% CI:3.63~10.81)是维吾尔族成人支气管哮喘的主要影响因素。结论 维吾尔族成人支气管哮喘是生活方式、环境及遗传等多种因素共同作用的结果,应加强对相关影响因素的预防及治疗,减少哮喘的发生,改善哮喘患者生活质量。  相似文献

Aim:   Human epidermal growth factor receptor 2 (HER2) overexpression is associated with poor prognosis and the frequency of HER2 positivity in breast cancer patients varies among different regions of the world. We studied HER2 expression in Turkish breast cancer patients.
Methods:   HER 2 expression was evaluated immunohistochemically in 107 breast cancer patients. HER2 expression was reported as negative or positive (3+) according to cellular membrane staining characteristics. The frequency of HER2 overexpression, distribution according to clinical characteristics, effect on survival and effect of chemotherapy on survival in relation to HER2 overexpression was evaluated.
Results:   The median age of patients was 49 years (range 27–76). HER2 was 3+ in 34 patients (31.8%). There was no significant difference in age, menopausal status, histopathology, lymph node involvement, stage and estrogen and/or progesterone receptor positivity in relation to HER2 expression. Forty-three patients (40.2%) relapsed and 21 patients (19.6%) died during the follow-up period. There was no significant difference in the relapse rate, distribution of relapse sites and death rate in relation to HER2 expression. The 3- and 5-year disease free survival rates were 67.1 and 40.5%, and the overall survival rates were 87.5 and 66.1%, respectively. Survival rate and calculated survival time were relatively shorter in HER2 3+ patients than in non-HER2 3+ patients, but these differences were not statistically significant. HER2 status did not affect survival period according to chemotherapy group.
Conclusion:   Immunohistochemistry findings of HER2 expression in Turkish breast cancer patients were similar to those found in the published reports. A shorter survival period was observed in HER2 3+ patients, but the difference was not statistically significant.  相似文献

Caecal diverticulitis is an uncommon phenomenon in western countries. The clinical diagnosis is often difficult as it mimics other acute abdominal conditions like appendicitis, colitis or neoplasia. Diagnosis is often made at operation. Operative strategy has been controversial and there is no broad consensus emerging. We report the case of a 71-year-old woman, known to have chronic obstructive pulmonary disease, who presented acutely with right iliac fossa pain. A clinical diagnosis of appendicitis was made. At laparoscopy, a solitary, inflamed, gangrenous caecal diverticulum was found. A laparoscopic stapled diverticulectomy was performed. The patient made a steady post-operative recovery. Histology confirmed diverticulitis. We conclude that stapled diverticulectomy for solitary caecal diverticulitis is a safe and effective surgical strategy when confronted with this scenario.  相似文献

目的:观察静心电针法治疗围绝经期综合征的临床疗效。方法:将符合标准的围绝经期患者60例随机分为治疗组(30例)和对照组(30例)。治疗组给予静心电针法治疗,对照组给予克龄蒙治疗,均治疗3个周期。分别于治疗前、治疗1个月、治疗3个月(即治疗结束)、治疗后3个月及治疗后6个月进行随访,采用改良的Kupperman指数(KI)进行症状评分,并于治疗前、治疗结束各检测1次血清雌二醇(E2)、卵泡刺激素(FSH)、黄体生成激素(LH)。结果:治疗组和对照组的总有效率比较差异无统计学意义(90.00%vs.93.33%,P>0.05)。2组KI评分,治疗后各时间点与治疗前比较差异均有统计学意义(P<0.01),2组之间各时间点差异无统计学意义(P>0.05),2组在治疗期间,KI均有下降,当治疗结束后3个月与6个月时,KI评分稍有上升,对照组上升稍多,但2组之间差异无统计学意义(P>0.05)。2组治疗后,性激素水平均得到改善(P<0.01),但2组之间差异无统计学意义(P>0.05)。结论:静心电针法治疗围绝经期综合征,安全、疗效好,值得推广应用。  相似文献
