【摘要】 目的 发现提示早期Ⅴ型狼疮性肾炎（lupus nephritis，LN）的指标。 方法 2004年 1月-2009年11月24例经肾活检诊断为Ⅴ型LN患者，与同期50例膜性肾病伴抗核抗体（antinuclear antibody，ANA）阳性患者、50例膜性肾病ANA阴性患者，以及13例膜性肾病ANA阳性且肾组织荧光为“满堂亮”患者的一般资料、肾病表现、肾脏病理以及实验室指标进行比较。 结果 Ⅴ型LN与膜性肾病ANA阴性的患者相比，两组的性别、起病年龄、血红蛋白、补体水平、内皮和系膜增殖的比例等有明显差异。膜性肾病ANA阳性患者的临床和病理表现更接近于ANA阴性的膜性肾病，但其性别比仍以女性居多。而膜性肾病ANA阳性伴“满堂亮”的患者在性别、肾病表现、血红蛋白、补体水平等方面与Ⅴ型LN更为接近。 结论 膜性肾病ANA阳性患者具有异质性，其中肾脏病理表现为“满堂亮”的患者可能系早期Ⅴ型LN。【Abstract】 Objective To find out the clinical and pathological characteristics of early pure class Ⅴ lupus nephritis (LN). Methods A total of 24 patients with pure class Ⅴ LN diagnosed between January 2004 and November 2009 were included, and were compared with 50 antinuclear antibody (ANA)-positive patients with membranous nephropathy (MN) and 50 ANA-negative patients with MN. The clinical and pathological characteristics, laboratory test results were compared between the two groups. Then, 13 patients with "full house" fluorescence in renal biopsy specimens were chosen from the group of ANA-positive membranous nephropathy, whose clinical characteristics and laboratory test were compared with class Ⅴ LN patients. Results There were significant differences in sex ratio, age, positive rate of hepatitis B surface antigen (HBsAg), levels of hemoglobin, white blood cell, platelet,complement, endothelial and mesangial proliferation between class Ⅴ LN and ANA-negative MN group. However, the sex ratio, levels of white blood cell, platelet were similar between class Ⅴ LN and ANA-positive MN group. The renal biopsy specimens in patients with ANA-positive MN with "full house" fluorescence were similar with those in the patients with class Ⅴ LN in sex ratio, renal injury, hemoglobin and complement and the positive rate of hepatitis B surface antigen. Conclusion The demographic information and clinical manifestations in patients with class Ⅴ LN were similar to those in patients with ANA positive MN, especially in the patients wiht ANA-positive MN with "full house" fluorescence in renal biopsy specimens.
摘要:目的:探讨接受超声引导下经直肠前列腺穿刺活检术(transretal prostatic biopsy,TPB)检查的临床护理相关问题,为前列腺穿刺活检临床护理提供参考。方法:通过心理疏导接解除者术前对TPB的恐惧心理,明确TPB是比较安全、可靠的、不可替代的检查方法,了解手术过程、护理方法和一般并发症,提高TPB的检查效果及护理质量。结果:71例患者进行TPB检查,全部患者均能主动配合检查操作,检查术中并发迷走神经心血管反射1例,术后并发血尿4例,短期内疼痛5例,均早期发现,给与相应的护理与治疗后治愈。结论:TPB是前列腺占位性病变患者有效的定性有创性检查方法,对行TPB检察患者患者应采取针对性的护理措施,提高护理质量及检查安全性。 Abstract: Objective: To investigate correlative nursing measure of patients with transretal prostatic biopsy (TPB) guided by ultrasound, provide reference for clinical nursing of TPB. Methods: We dismissed patient’s fear by psychological nursing, and explained that TPB was a safe, reliable and nosubstitutive checking, and help them understand procedure of operation, nursing measure and common complication, so as to improve effect of checking and quality of care. Results: Seventyone patients received checking with TPB, all patients could initiativiy go with checking, one patient took place pneumogastric nerve reflect, 4 patients take place hematuria postoperation, 5 patients feel soreness in shortterm. All complications were found in morning, and were cure by nursing and treatment. Conclusion: TPB is valid checking method to occupy lesion of prostate for qualitation. Because TPB is a traumatic operation, homologous nursing measure must be take to improve safety of TPB and quality of care.

ObjectiveTo summarize the current status and advances of sentinel lymph node biopsy (SLNB) technique in breast cancer. MethodsThe pertinent domestic and overseas literatures were reviewed and the localization, harvest, status assessment, indications, and complications of SLNB were analyzed. ResultsSLNB could accurately locate and pick out sentinel lymph node (SLN) in breast cancer. The development on imaging examination and pathological techniques promoted the assessment of SLN, and the indications of SLNB were expanding. The complication rate of SLNB was low and the technique could accurately predict axillary lymph node staging and direct selective axillary lymph node dissection. ConclusionsSLNB has been an important method of surgical therapy in breast cancer, but the operation process needs to be further standardized to decrease the false negative rate. Continuative attentions shall be paid to the problems such as the false positive and controversial indications.
Objective To explore the clinical value of only using blue dye as tracer in the sentinel lymph node biopsy (SLNB) of breast cancer. Methods SLNB was performed with the guidance of the combination of blue dye and isotope in all patients enrolled. SLNB data of blue dye only, and the combination method was recorded respectively for analyses. Results Three hundred and eight patients were enrolled in this prospective study. Significant differences were found in the identification rate (IDR, 93.5% vs. 99.4%, P=0.000), the false negative rate (FNR, 14.8% vs. 3.3%, P=0.007), the accuracy rate (AR, 89.6% vs. 97.8%, P=0.006), and the negative predictive value (NPV, 74.0% vs. 93.3%, P=0.012) between the blue dye alone and the combination method. The IDR and the FNR of the two methods were not significantly associated with the patient age, tumor size and location, histopathological type, type of biopsy and breast surgery, or ER, PR, and HER-2 status (all Pgt;0.05). The FNR of blue dye alone was significantly associated with clinically suspicious turgescence of axillary lymph nodes (P=0.042) and decreased followed by the increased number of sentinel lymph nodes obtained (P=0.000). Conclusions Compared with the combination method, SLNB guided with blue dye alone had significantly poorer IDR, AR, and NPV, and higher FNR. It is recommended that the combination of dye and isotope should be adopted for the guidance of SLNB in clinical practice rather than the use of blue dye alone.
Objective To investigate the roles of cell apoptosis and the gene expressions of Fas, FasL, bcl-2 and bax in acute rejection of pancreaticoduodenal transplantation and to evaluate the function of duodenum biopsy for early detection of rejection in rats. Methods Wistar and SD rats were divided into two groups: ①Wistar rats that underwent allogenic pancreaticoduodenal transplantation from the organs of SD rats; ②Wistar rats that received homogenic transplantation. The grafts were then harvested on day 3, 5 and 7 after the transplantation, and all graft samples were observed with HE staining and TUNEL was also used to detect apoptotic cells. The expressions of Fas, FasL, bcl-2 and bax were measured by immunochemical method. According to Nakhleh’s score, pathologic features of transplanted pancreas and duodenum were ranged from one to three scores in order. Results The percentage of same or different scores between the pathological scores of pancreas and duodenum in allogenic pancreaticoduodenal transplantation group were 61.1% (11/18) and 38.9% (7/18) respectively, and there were 6 specimens of pancreatic tissue got higher scores with only one higher score for duodenum. There were significant differences of histopathologic rejection scores and apoptotic indices between the two groups, respectively (P＜0.05， P＜0.01). Apoptotic indices of pancreas and duodenum both showed positive correlations with histopathologic rejection scores (r=0.965， P＜0.01; r=0.942, P＜0.01). The rejection score and apoptotic index elevated, the expression of FasL increased, bcl-2 decreased, and Fas and bax changed over time after operation. Conclusion Apoptosis maybe significantly positive correlated with the degrees of damage of the acute pancreaticoduodenal allograft rejection, and the apoptotic index maybe valuable to estimate the damage. FasL and bcl-2 were significantly related to the impairment of acute pancreatic allograft rejection as well. Duodenum biopsy may contribute to the early diagnosis of the rejecting transplanted tissues.
Objective To understand the current research status of sentinel lymph node (SLN) biopsy in colorectal cancer. Methods Literatures about the application of SLN biopsy in the field of colorectal surgery were collected and reviewed. Results The results of SLNs biopsy accurately reflected the status of the nodal basin. Focused examination of the SLNs could identify micrometastases that might otherwise had been missed by standard histopathological analysis, thus upstaged this group of patients. Conclusion SLN biopsy represents a new and effective technique to predict the tumor status of regional lymph nodes, which offers a potential alternative to improve the accuracy of tumor staging in colorectal cancer.
ObjectiveTo introduce the current status of clinical application, value and perspective of fiberoptic ductoscopy.MethodsThe related literatures on advances in clinical application of fiberoptic ductoscopy were reviewed.ResultsFiberoptic ductoscopy is now widely used in breast diseases, especially complicated with nipple discharge, and it has a higher accuracy rate than routine examinations.
