应用5-氨基-γ-酮戊酸(ALA)诱导的卟啉荧光诊断(FDAP)中,肉眼可观察到原卟啉IX(PpIX)沉积。因操作重复性低,且涉及PpIX肿瘤选择的机制知之甚少,所以解释荧光数据仍有些困难。本研究中,作者要研究FDAP后银屑病和日光性角化病(AK)患者皮损的PpIX沉积情况。基于此目的,将患者脱屑区皮损和无皮损正常皮肤用20%ALA油孵育3h,进行FDAP,取强荧光区皮损和无皮损处皮肤活检。从活检标本中提取PpIX、蛋白质和双链DNA行荧光分光光度法定量,用图像分析软件分析由FDAP获得的数字图像。 相似文献

目的:探讨肝胆外科手术危重患者重返重症监护病房(ICU)的原因及其预后影响因素.方法:回顾性分析本院ICU2010年1月至2013年12月收治的785例肝胆疾病患者的临床资料,采用单因素及多因素Logistic回归分析患者重返ICU的原因及其预后影响因素.结果:785例患者中72例(9.20%)重返ICU,重返ICU患者中病死28例(38.90%),存活44例(61.10%).与存活组相比,死亡组患者年龄较大,首次转出ICU及首次重返ICU时急性生理学及慢性健康状况评分系统Ⅲ(A-PACHEⅡ)评分较高,首次转出ICU及首次重返ICU时格拉斯哥昏迷评分(CGS)较低,差异有统计学意义(P<0.05).与存活组相比,死亡组术后出血、术后感染、心血管并发症、肺部感染、合并感染性休克、脓毒症及多器官功能障碍综合征(MODS)发生率较高(P<0.05).经多因素Logistic回归分析可知,患者首次转出、重返ICU时APACHEⅡ评分、首次转出、重返ICU时CGS评分、合并MODS是影响肝胆外科手术患者术后重返ICU的独立危险因素.结论:严格掌握肝胆重症患者转出ICU时的指征,积极预防术后并发症,采用APACHEⅡ评分及GCS评分动态观察患者病情,可有效降低肝胆重症患者重返ICU率,促进患者预后. 相似文献

Background: 1% of breast cancers occur in men.The etiology is obscure. An elevated BMI has been postulated to be a cause.
Methods: All male breast cancer patients operated from January 1990 to May 2001 were retrospectively reviewed. Relation between
BMI and male breast cancer was examined. Results: 43 males underwent breast surgery for breast cancer during this period.
3 patients were excluded from the study because of other risk factors for breast cancer.The average BMI of 40 patients was
26.54 kg/m2, which is mildly above the level for normal weight. Conclusions: Excessive adipose tissue may increase risk of male breast
cancer. 相似文献

Hepatic adenomatosis: MRI demonstration with the use of superparamagnetic iron oxide 总被引:2,自引:0,他引:2
This case report describes a case of a 38-year-old woman with hepatic adenomatosis. MRI revealed five hyperintense nodular liver lesions on T1-weighted images which were hypo-isointense with the liver parenchyma on T2-weighted images. Serial gadolinium-enhanced images did not reveal distinctive imaging findings. With the use of superparamagnetic iron oxide (SPIO) particles, hyperintense adenomas revealed signal loss on T1-weighted images after SPIO. Two subcapsular adenomas were resected based on MRI findings and histopathology confirmed MRI diagnosis. 相似文献

间硝苯地平对血管紧张素Ⅱ促进血管平滑肌细胞增殖和蛋白质合成的影响 总被引:2,自引:0,他引:2
以培养血管平滑肌细胞(vascularsmcothmusclecell,VSMC)为模型,观察了间硝苯地平(m-nifedipine,m-Nif)对血管紧张素Ⅱ(angiotensinⅡ,ANGⅡ)促进VSMC增殖和蛋白质合成的影响。结果表明,m-Nif抑制ANGⅡ(100nmol·L-1)引起VSMC[3H]thymidine和[3H]leucine参入,并呈剂量依赖性。m-Nif(2×10-6mol·L-1)可抑制ANGⅡ对VSMC的刺激、DNA及蛋白质合成速率,分别降低了46%,58%,53%。提示m-Nif可抑制ANGⅡ对VSMC增殖和蛋白合成的促进作用。 相似文献

To date limited data exists that addresses the impact of urinary incontinence on sexual function. In the present study, we assessed sexual functions in patients with urinary incontinence and compared with healthy continent subjects by means of Female Sexual Function Index (FSFI) questionnaire. A total of 21 premenopausal incontinent women (three stress incontinence, nine overactive bladder and nine mixed incontinence) were enrolled in the study, and 18 healthy continent subjects served as controls. All subjects were asked to complete FSFI questionnaire and each FSFI domain scores including desire, arousal, lubrication, orgasm, satisfaction and pain were calculated. The mean scores in each domain were compared between the groups. Mean age of subjects with urinary incontinence and controls were 39.5+/-6.6 and 32.6+/-9.1 y, respectively. All domain scores were significantly lower in incontinent women except for pain. Among the incontinence types, no significant difference was determined in all domains of FSFI. Urinary incontinence significantly reduces sexual functions in premenopausal sexually active women. 相似文献

AIM: To examine the frequency and factors predisposing to candidiasis in the digestive tract in the early postoperative period after open heart surgery. METHODS: One hundred patients undergoing open heart surgery were enrolled in this study. Patients were divided into 2 groups in regard to Candida spp. colonization. Group A means increased Candida spp. colonization after open heart surgery (31/100). Group B indicates unchanged Candida spp. colonization after open heart surgery (69/100). Samples were obtained from both oral and anal mucosa in 3 different periods of operation: 1) preoperatively (stage 1), 2) at the end of the first hour in the intensive care unit (stage 2), 3) 24 hours after operation (stage 3). Findings were compared with both preoperative and intraoperative parameters. For fungal isolation Sabourauds dextrose agar and blood agar were used. RESULTS: In Group A (31), there was a significant relationship between the samples in stage 1 and 2 (p=0.031), and also a significance between stage 1 and 3 (p=0.048). Comparison between Candida positive and negative groups (Group A and B) did not reflect any statistical significance (p>0.05). CONCLUSIONS: Candida colonization in the alimentary canal in the early postoperative period after open heart surgery is due to individual preoperative features. However, early postoperative Candida colonization in the digestive tract is not a risk factor for sepsis unless the patient has an additional risk factor leading to prolongation of length of stay in the intensive care unit. 相似文献

A 64-year-old woman presented with a 2 week history of ptosis and medial-gaze paralysis of her left eye. Computed tomography scanning of the paranasal sinuses revealed an expansile, homogeneous lesion with no contrast enhancement in the sphenoid sinus. The mass was hyperintense on all MR sequences and there was extension of the mass to the left cavernous sinus and optic canal. Operation revealed a large mucocele. Third nerve palsy disappeared 4 weeks after operation. Because the spread of mucoceles is variable, they may cause different symptoms. Radiological evaluation, especially computed tomography and magnetic resonance imaging, are useful in diagnosis of mucoceles and help to explain the clinical symptoms by showing the spread of the lesion. 相似文献
