Some international guidelines suggest that partial nephrectomy can be applied also in clinical T1b tumors. The aim of this study was to evaluate the feasibility of partial nephrectomy for tumors larger than 4 cm. We reviewed the medical records of 1280 patients who underwent partial nephrectomy and had pathologically confirmed malignancy. Patients were categorized into two groups by the size of tumors on computed tomography image, with a cutoff value of 4 cm. The oncologic and functional outcomes were compared between the two groups. Recurrence-free survival after surgery was estimated using the Kaplan-Meier method. Of the 1280 patients, 203 patients (15.9%) had renal tumors larger than 4 cm. There were significantly more exophytic tumors (P & 0.001) and the R.E.N.A.L. scores were significantly higher (P & 0.001) in partial nephrectomy &4 cm. Mean ischemic times were significantly different (P & 0.001). After 24 months, mean creatinine level between partial nephrectomy &4 cm and partial nephrectomy ≤4 cm was not different significantly (P=0.554). And the percent changes of glomerular filtration rate after partial nephrectomy were not different at last follow-up (P = 0.082). The 5-year recurrence-free survival rates were 96.6% in partial nephrectomy ≤4 cm, and 94.5% in partial nephrectomy &4 cm (P = 0.416). Based on the present findings, partial nephrectomy for tumors larger than 4 cm showed comparable feasibility and safety to partial nephrectomy for tumors ≤4 cm considering oncologic and functional outcomes, despite longer operative and ischemic time.Do you want to read the rest of this article?Request full-text

右美托咪定对食管癌根治术患者围手术期肺动态顺应及炎性应激反应的影响
【摘要】：目的:对右美托咪定在食管癌根治术患者围手术期肺动态顺应及炎性反应应激反应的影响进行研究。方法:选取食管癌根治术60例患者为研究对象,采用随机数字表法分为盐酸右美托咪定组(A组)和对照组(B组)各30例。手术开始时,A组以0.4μg/(kg·h)的速率持续泵注盐酸右美托咪定至术毕前30B组静脉输注等容量0.9%NaCl溶液。将手术时间点分为:麻醉诱导前为T_0,插管后5 min为T_1,手术开始后30 min为T_2手术开始后60 min为T_3,手术开始后90 min为T_4,手术结束前30 min为T_5,拔管时为T_6,拔管后3 min为T_7,手术后24 h为T_8。记录T_1~T_6气道压、肺顺应性。检测T_0、T_4、T_7、T_8时点患者外周血中肿瘤坏死因子(T_NF-α)及肺表面活性蛋白D(SP-D)浓度。结果:在T_4时点时A组肺动态顺应性为(45.2±10.2)ml/cm H_2O,与B组相比显著较高,差异有统计学意义(P0.05);在T_4、T_7及T_8时点A组血清中T_NF-α及SP-D的浓度较B组均显著较低,差异有统计学意义(P0.05)。结论:右美托咪定有助于提高患者围手术期非动态顺应性,并且能有效降低炎性应激反应。

400-819-9993Plasma‐modified Nylon 4 membrane for dialysis
See all >21 CitationsSee all >14 References
AbstractThe effects of plasma treatment conditions, such as supply power, treatment time, gases used in reactor, surface energy, water content, dialysis permeability, partition coefficient, diffusion coefficient, and free volume of Nylon 4 membranes, were studied. The solutes considered for dialysis system were NaCl, urea, and MgCl2. The permeabilities of NaCl and urea of membranes with plasma treated in argon at 80 W for 20 min are 5.57 × 10-5 and 5.89 × 10-5 cm2/min, respectively. Much higher permeabilities of NaCl and urea obtained by oxygen plasma-treated membranes under 20 W and for 20 min are 30.74 × 10-5 and 17.66 10-5 cm2/min, respectively, compared to that of untreated Nylon 4 membranes.Do you want to read the rest of this article?Request full-text
