Sarcopenia with systemic inflammation can predict survival in patients with hepatocellular carcinoma undergoing curative resection

BackgroundThis study aimed to examine the prognostic significance of sarcopenia combined with systemic inflammation in patients who underwent curative hepatectomy for hepatocellular carcinoma (HCC).MethodsBetween January 2010 and July 2019, we identified 159 patients with HCC who underwent curative hepatectomy at three institutional centers. We retrospectively analyzed clinicopathological outcomes, surgical outcomes, platelet lymphocyte ratio (PLR) as a systemic inflammatory marker, and computed tomography (CT)-assessed sarcopenia at the third lumbar vertebra level (L3).ResultsSarcopenia was noted in 74 (46.5%) of 159 patients and was significantly associated with male sex, low body mass index (BMI), and high PLR. In the multivariate analysis, sarcopenia [hazard ratio (HR): 2.127, P=0.026] and high PLR (HR: 1.971, P=0.038) were associated with a decrease in overall survival (OS) but not in recurrence-free survival (RFS). The combination of sarcopenia and PLR status stratified the 5-year OS into 82.0% (non-sarcopenia and a low PLR), 68.3% (sarcopenia or a high PLR), and 44.4% (sarcopenia and a high PLR) (P=0.001). In the multivariate analysis, “sarcopenia and a high PLR” and “sarcopenia or a high PLR” were revealed to be significant predictors of OS (HR: 4.300, P=0.001 and HR: 2.723, P=0.010, respectively).ConclusionsSarcopenia and high PLR were significantly associated with poor OS. The combination of these two factors may be useful for predicting survival of patients with HCC undergoing curative hepatectomy.     

Application of Alpha1-adrenergic antagonist with extracorporeal shock wave lithotripsy for lower ureteral stone

OBJECTIVE: To evaluate the efficacy of alpha1-adrenergic antagonist in the medical management of lower ureteral stone with extracorporeal shock wave lithotripsy (ESWL). METHODS: A total of 80 patients with stone located in lower ureter were randomly divided into two groups. Group 1 served as control and group 2 received tamsulosin (0.4 mg, once daily) after ESWL. All patients were observed for 2 weeks and asked to compile a diary about renal colic, stone expulsion, use of analgesic drugs, and side effects of medical therapy. RESULTS: During 2 weeks, stones were expulsed in 18 patients (45.0%) of group 1 and in 31 patients (77.5%) of group 2. The expulsion rate between group 1 and group 2 was significantly different (P < 0.01). Eight patients (20.0%) in group 1 and 2 patients (5.0%) in group 2 experienced renal colic relapse within 2 weeks and were administered with analgesics (P < 0.05). No side effect in group 1 was reported, except that 2 patients in group 2 complained of slight dizziness. CONCLUSIONS: Tamsulosin (alpha1-adrenergic antagonist) can improve the stone-free rate of lower ureteral stones after ESWL and reduce the relapse of renal colic. As a safe and effective agent, it can be regarded as an auxiliary clearance method after ESWL for lower ureteral stones.     

小鼠脊髓发育候选基因Wnt7b的初步研究

目的:探讨Wnt7b基因及Wnt信号系统分子对小鼠脊髓发育的作用。方法:基因测序比较A/J和C57BL/6J两种小鼠Wnt7b基因开放阅读框架序列差异;以RT-PCR方法测定Wnt7b基因在两种小鼠组织中的表达差异;免疫组化法测定Frizzled在2种孕14天胎鼠脊髓上的表达和分布。结果:测序结果中发现两种小鼠Wnt7b开放阅读框架序列结构具有差异;在2种小鼠8种组织中,脊髓、肌肉、脾和肾中的Wnt7b基因表达具有明显差异;免疫组化的测定表明,发育14天的胎鼠脊髓上的Frizzled表达强度和分布范围具有显著差异,尤其是A/J小鼠在神经管周围表达明显强于C57BL/6J。结论:基因表达差异和基因结构差异提示,Wnt7b基因与脊髓发育具有一定的关联,应为一脊髓发育候选基因;Frizzled的强表达与脊髓发育的抑制相关,Wnt7b的信号转导途径介导了控制脊髓发育的过程。     

磁共振脊髓水成像在脊柱病变中的应用

目的探讨磁共振脊柱水成像在脊柱病变诊断中的作用。方法使用日本东芝ExcelART1.5T超导磁共振机,对110例患者进行检查,分别做二维及三维成像,并配合脂肪抑制及预饱和技术,对三维图像做最大强度投影重建,将三维图像做多角度观察。结果MRM可显示椎管内“造影柱”的形态,椎管内外不同病变对造影柱造成的压迫各有特征,硬膜外病变导致患侧造影柱狭窄,硬膜下病变造成患侧造影柱扩大,脊髓向对侧移位,髓内病变造成造影柱均匀变窄。结论MRM对脊柱各种病变所导致的椎管改变可清晰显示,通过对造影柱形态的观察,可以对病变进行定位或定性的诊断,结合MR平扫诊断更为准确。
