Evaluation of the MagNA Pure LC used with the TRUGENE HBV Genotyping Kit.

BACKGROUND: The current manual sample processing method recommended for use with the TRUGENE HBV Genotyping Kit (TRUGENE HBV; Bayer HealthCare LLC, Tarrytown, NY) is labor-intensive and may be prone to specimen cross-contamination. Recent evaluations of the MagNA Pure LC (MP; Roche Applied Science, Indianapolis, IN) suggest that it is suitable for automated, contamination-free extraction and purification of viral nucleic acids from large-volume (1.0 mL) serum or plasma specimens. OBJECTIVES: We evaluated the MP Total Nucleic Acid Isolation Kit--Large Volume (Roche Applied Science) in conjunction with TRUGENE HBV to establish the analytical sensitivity (threshold titer) of the assay, in HBV DNA International Units (IU)/mL, for obtaining consistent, interpretable sequence data from TRUGENE HBV. STUDY DESIGN: HBV analytical standards, prepared as 10 replicates (1.0 mL each) at each of the following concentrations: 200, 1000, 5000, and 10,000 IU/mL, were processed by MP and analyzed by TRUGENE HBV according to manufacturer's instructions. Performance of TRUGENE HBV used in conjunction with MP sample processing was evaluated further using 22 clinical serum specimens containing low titers of HBV DNA. RESULTS: All replicates of HBV analytical standards at 1000, 5000, and 10,000 IU/mL yielded interpretable TRUGENE HBV sequences, whereas interpretable sequences were obtained in 90% (9 of 10) of the replicates at 200 IU/mL. TRUGENE HBV sequences were interpretable in 86% (19 of 22) of the clinical specimens studied. CONCLUSIONS: MP sample processing is efficient and suitable for use with TRUGENE HBV. When combined with MP sample processing, TRUGENE HBV yielded interpretable sequences from HBV analytical standards and clinical serum specimens with HBV DNA titers of > or =200 IU/mL.     

Pancreatic cancer–Palliative therapy: surgery (bypass/resection)

Objective: We compare the outcome of palliative pancreaticoduodenectomy and palliative surgical bypass in patients with advanced pancreatic carcinoma in our hospital. Recent published related articles are also reviewed. Methods: A respective analysis was performed comparing the perioperative parameters and outcome of 20 patients who underwent pancreaticoduodenectomy with a gross suspected cancer residue and 30 patients who underwent a surgical bypass, all of the patients were diagnosed as in advanced stages intra-operatively. Results: The two groups were comparable with patient characteristics, including age, gender, initial symptoms and concomitant major organ diseases. Tumors are similar in size and intra-operatively diagnosed as in advanced stages in both groups. All of the patients in the resection group were microscopically proved having cancer residue. One postoperative mortality occurred in the resection group (5%), zero in the bypass group (P > 0.05). Overall complications were significantly higher in the resection group (30% vs. 0, P < 0.01), including 2 patients developed Acute Respiratory Distress Syndrome (ARDS), zero in the bypass group (P < 0.01); hemorrhage and transfusions in the resection group were much more than that in the bypass group (P < 0.05). Hospital stay after resection was significantly longer than bypass (20 vs. 12 days, P < 0.01). Hospital fee after resection was 4 times more than after bypass (median 61.500 vs. 15. 300 yuan, P < 0.01). Survival was significantly longer after resection (median 12.2 vs. 7.1 months, P < 0.01). Conclusion: Our results show that palliative resection in advanced pancreatic carcinoma lengthens the survival time of the patients, but this is paid for significantly higher complications than bypass.     

可调节型充气体位垫的制作和应用

手术中常用体位垫来调整体位及预防褥疮,但以往使用的软垫、海绵垫等却不可根据手术及术中的要求来调节高度,我科对其进行研究并利用现有材料,将其改进制成可调节型充气体位垫,投入临床试用,效果较好。现介绍如下。1材料与制作取上海百特医疗用品有限公司生产的3L容量的氯化钠溶液软包装袋一个,将其中一个出口封闭,使其不漏气。将一根长30cm~50cm长的橡胶管固定于另一个出口,使其不漏气,并将输血器调节器穿于橡胶管上,调节滚轴,起开关作用。连接气压止血器充气,即成可调节型充气调节体位垫。2使用方法根据手术要求将橡胶管连接于气压止血器…

18F-氟脱氧葡萄糖PET和PET-CT在结直肠癌术后复发或转移中的应用价值

临床常规检查方法对结直肠癌术后复发转移的诊断及再分期有一定局限性，^18F-氟脱氧葡萄糖（^18F-FDG）PET作为一种功能代谢显像检查，能早期探测到肿瘤有无复发，准确鉴别术后瘢痕与复发，且能提供全面、准确的再分期信息，有助于制定合理的临床治疗方案，但仍存在假阳性及假阴性诊断。PET-CT融合显像有助于PET图像的正确解释，定位、定性准确度高，应用前景广阔。
