目的 探讨肾移植受者BK病毒感染的诊断方法、监测指标.方法 采集234例肾移植受者的血、尿样本,行BKV尿沉渣细胞学计数与实时荧光定量PCR检测方法.结果 234例受者的尿Decoy细胞、BK病毒尿症与病毒血症的阳性率分别为33.3%、33.3%和16.2%.尿Decoy细胞阳性者Decoy细胞中位数水平为6个/10HPF,BKV DNA阳性者尿液和外周血BKV中位数水平分别为7.62×103 copy/ml和7.61×103 copy/ml.尿液BKV阳性率较外周血明显升高(P=0.000).尿液Decoy细胞计数与尿液BKV含量相关(γ=0.59,P=0.000),但尿液和外周血中BKV含量无明显相关性(P=0.14).结论 肾移植受者易发生BKV再活化,定量尿沉渣细胞学检测简单、易行、敏感,可以做为BKV活化的指标,间接反映肾脏病理情况,也可检测血、尿BKV DNA了解病毒活化情况、筛查BKV相关的移植肾肾病.  相似文献

肾移植患者术后BK病毒感染的检测及危险因素分析   总被引:2,自引:0,他引:2  
目的:检测肾移植患者术后BK病毒(BKV)感染率,分析BKV感染的危险因素.方法:收集63例肾移植患者术后第1、 2、3、4、6 和8个月的尿液和血液标本,实时荧光定量PCR方法检测标本中BKV DNA含量,并根据检测结果进行分组:尿液、血液BKV DNA均阳性者为UV PV 组,尿液阳性而血液阴性者为UV PV-组,尿液、血液均阴性者为UV-PV-组.尿沉渣涂片寻找含有病毒包涵体的脱落尿路上皮细胞(Decoy细胞),并对Decoy细胞进行细胞免疫学检测;对临床高度怀疑为BK病毒相关性肾病患者(BKVAN)行移植肾活检.比较3组患者的年龄、术前冷缺血时间、术前血透时间、免疫抑制方案、群体反应性抗体(PRA)致敏程度、术后是否合并其他病毒感染等临床指标的差异,应用Logistic回归法分析筛选BKV感染和BKVAN发生的危险因素.结果:UV PV-组19例(30.1%), UV PV 组患者9例(14.3%),UV-PV-组患者35例;前两组首次发现BKV的中位时间分别为术后4个月和3个月.63例患者Decoy细胞检出率为39.7%,Decoy细胞免疫染色阳性率为54.3%.1例移植肾活检未见BKVAN表现.Logistic回归法发现BKV DNA感染与冷缺血时间有显著联系(P=0.048;OR=1.151),与其他指标无显著相关(P=0.069).结论:实时荧光定量PCR能较好地监测术后BKV感染,术后3~4个月是BKV排泄高峰,术前冷缺血时间可能是BKV感染的危险因素之一,而术后免疫抑制方案对BKV感染可能无明显影响.  相似文献

目的探讨肾移植受者术后BK多瘤病毒的感染特征和干预时机。方法回顾性分析2013年1月~2018年1月在本中心检测尿液 BKV载量≥1.0×104 copy/mL的157例肾移植受者的临床资料,选择69例同期接受移植且尿液BKV载量始终<1.0×104 copy/mL 肾移植受者作为对照。结果157例BKV感染再激活受者中出现尿BKV阳性60例(38.2%)、BKV尿症66例(42.0%)、BKV血 症31例(19.7%)。BKV阳性患者与BKV阴性患者相比,尿隐血阳性率更高,差异有统计学意义(P<0.05)。受者尿液BKV载量 变化率与他克莫司谷值血药浓度变化率呈正相关(r2=0.351, P<0.05)。首次发现BKV再激活时,BKV阳性患者平均eGFR低于 基线水平(eGFR=60 mL/min·1.73 m-2)。干预后至末次随访,尿BKV阳性组平均eGFR可恢复至正常值,BKV尿症组和BKV血症 组肾功能有所改善但均未达到基线水平。结论肾移植术后部分受者尿隐血阳性与BKV再激活状态相关,BKV载量对免疫抑制 剂血药浓度的改变敏感。在BKV复制早期进行干预,适度减少免疫抑制剂剂量,能够有效控制BKV复制、维持移植肾功能。  相似文献

目的 探讨肾移植受者BK病毒(BKV)感染的诊断及治疗方法.方法 选取肾移植术后48个月内的患者共227例.采集其血、尿样本,行BKV尿沉渣细胞学计数与实时荧光定量PCR检测病毒拷贝.对部分肾移植受者进行移植肾活检.将尿或血中BKV DNA阳性患者80例分成干预组(51例)与对照组(29例).干预组进行调整免疫抑制剂:19例环孢素A(CsA)减量,22例他克莫司(FK506)减量,10例FK506转换成CsA;对照组不进行干预,并且密切监测急性排斥反应.干预3个月后再次检测,比较组内和组间干预前后BKV活化指标的差异.结果 227例受者的尿decoy细胞、BK病毒尿症与病毒血症的阳性率分别为33.O%、33.5%和15.4%.干预组干预后尿decoy细胞、尿和血BKV数量的中位水平均为O,明显低于干预前(5.0个/10HP,1.50 x 104拷贝/ml,0拷贝/ml,均P<0.01).对照组观察前后尿decoy细胞、血BKV数量的中位水平差异无统计学意义(6.0个/10HPvs 5.0个/10HP、0拷贝/ml vs 0拷贝/ml,均P>0.05),尿BKV数量观察结束时上升(观察前:0.79×104拷贝/ml,观察后:2.21 x104拷贝/ml,P<0.01).上述各项指标干预前后的差值在干预组与对照组间差异均有统计学意义(均P<0.05).干预过程中所有患者均未出现急性排斥反应.确诊BKV相关性肾病4例,其干预治疗后尿decoy细胞计数以及血、尿BKV DNA均明显降低,移植肾功能有所恢复.结论 定量尿沉渣细胞学检测简单、易行、敏感,可以作为BKV活化的指标,间接反映肾脏病理情况.也可检测血、尿BKV DNA了解病毒活化情况、筛查BKV相关的移植肾肾病.减少免疫抑制剂剂量或换FKS06为CsA治疗肾移植术后BKV感染效果良好.  相似文献

CASE HISTORY A female patient, 46 years old, head of the foreign affairs department of a certain university in Beijing, paid her first visit on October 9, 2006, with the chief complaint of vomiting for one month. She got vomiting after meals in early September. Before that, she had discomfortable sensation in the stomach due to angry with others, but she didn't pay much attention. Later, it developed into vomiting after eating. After the vomiting, the discomfort would be relieved, but with slight hypodynamia. She was once diagnosed as having 'neurogenic vomiting'. Having taken some western and Chinese drugs, the above symptoms were a little bit improved, but she would have nausea upon eating and with regurgitation. Because of the fear for vomiting, she did not dare to have food intake, with body weight reduction of 6 kilos in one month.  相似文献

Radiotherapy and chemotherapy are the important modern medical therapies for malignant tumors,yet they can also bring about serious local and systemic toxic side reactions so to decrease the patient;'s life quality,manifested by a series of consumptive symptoms.Having engaged in the combined work of Chinese and western medicine for nearly 50 years,the research fellow Qiu Baoguo in Henan Provincial Academy of TCM has developed his unique views on the TCM study of consumptive syndromes.The author of this essay had once the fortune tO follow Dr.Qiu in clinic,and specially would like to introduce in the following Dr.Qiu's experience in treating consumptive syndromes after radio-chemotherapies for patients with malignant tumor.  相似文献

OBJECTIVE: To observe therapeutic effects of the comprehensive therapy of acupuncture-moxibustion and Chinese Tuina for treatment of insomnia due to deficiency of both the heart and spleen. METHODS: 92 cases were divided randomly into the treatment group (treated by acupuncture-moxibustion and Chinese Tuina) and the control group (treated by acupuncture-moxibustion). RESULTS: The therapeutic effect of the treatment group was obviously superior to that of the control group (the CHI2 test showed P < 0.01). CONCLUSIONS: The comprehensive therapy of acupuncture-moxibustion and Chinese Tuina can give marked therapeutic effects for treatment of insomnia due to deficiency of both the heart and spleen.  相似文献

Objective: To investigate if there are the CK-19, PDX-1, Nestin, Ngn3 positive cells in the donor islets of different purity in rats. Methods: Thirty male adult SD rats were randomly divided into 3 groups. Islets were isolated using digestion by ductal injection of collagenase. Group Ⅰ (n=10): Separating cell preparations were not purified, Group Ⅱ(n=10): Islet sediment was purified with 25% Ficoll400 ,Group Ⅲ (n=10): Islet sediment was purified with 25% and 11% Ficoll-400. The levels of protein of CK-19, PDX-1, Nestin and Ngn3 were detected by immunohistochemistry and the mRNA of CK-19, PDX-1, Nestin, Ngn3 was amplified by RT-PCR. Results: After two different purification methods applied, three islet preparations of different purities were obtained. The difference of islet purity was significant among various groups (P<0.05). Compared with group Ⅱ and group Ⅲ,the protein and mRNA of CK-19, PDX-1, Nestin,Ngn3 were both higher in group Ⅰ; group Ⅲ was poorly expressed. Conclusions: The three different islet purity donor islet have different CK-19, PDX-1, Nestin, Ngn3 positive cells within them, indicating that there are some islet stem cells in the purified donor islet.  相似文献

Objective:To investigate the optimum screening conditions of associated proteins in human psoriasis vulgaris by serum proteomics technique, and to screen the different expression proteins related with psoriasis vulgaris. Methods:Serum samples of peripheral blood were collected from newly diagnosed psoriasis vulgaris patients in the clinic, and 20 matched healthy persons. Serum albumin IgG was removed by filtering with ProteoExtract Albumin/IgG. After comparative proteomics analysis the different protein spots were identified using 2-DE and MS. Results :Electrophoresis figures with high resolution and reproducibility were obtained. Three different expression proteins were found only in the serum from psoriasis vulgaris patients, while nine other different proteins expressing from healthy volunteers. Conclusion:The protein expression was different in the serum between the psoriasis vulgaris patients and healthy volunteers. It was hoped that we could find the biomarkers related to psoriasis vulgaris by using proteomics.  相似文献
