微波消融与手术切除治疗原发性肝癌疗效比较

目的比较微波消融与手术切除治疗原发性肝癌的临床效果。方法选择2010年5月至2012年6月商丘市第四人民医院收治的原发性肝癌患者76例,按照治疗方法分为微波消融组(n=46)和肝切除组(n=30);对2组患者手术时间、术中出血量、住院时间、手术前后血清丙氨酸转氨酶(ALT)、总胆红素(TBIL)水平及术后并发症进行比较;术后随访5 a,观察2组患者1、3、5 a无瘤生存率,并进行比较。结果微波消融组患者手术时间、住院时间显著短于肝切除组(P<0.05),术中出血量显著少于肝切除组(P<0.05)。术前2组患者血清ALT、TBIL水平比较差异均无统计学意义(P>0.05)。肝切除组患者术后1 d和1周血清ALT、TBIL水平显著高于术前(P<0.05);微波消融组患者术后1 d和1周血清ALT、TBIL水平与术前比较差异均无统计学意义(P>0.05)。术后1 d和1周,微波消融组患者血清ALT、TBIL水平显著低于肝切除组(P<0.05)。微波消融组和肝切除组患者术后并发症发生率分别为4.35%(2/46)、23.33%(7/30);微波消融组患者术后并发症发生率显著低于肝切除组(χ~2=6.269,P<0.05)。微波消融组患者术后1、3、5 a无瘤生存率分别为67.39%(31/46)、39.13%(18/46)、28.26%(13/46),肿瘤复发率为54.35%(25/46);肝切除组患者术后1、3、5 a无瘤生存率分别为70.00%(21/30)、50.00%(15/30)、33.33%(10/30),肿瘤复发率为50.00%(15/30);2组患者术后1、3、5 a无瘤生存率及肿瘤复发率比较差异均无统计学意义(P>0.05)。结论微波消融治疗原发性肝癌创伤小,出血量少,住院时间短,可以更好地保护患者肝功能,且术后并发症发生率低,患者无瘤生存率、肿瘤复发率与肝切除术相当,具有较高的安全性及可行性。     

倾向性评分匹配法比较手术切除与微波消融治疗结直肠癌肝转移疗效

目的:探讨手术切除与微波消融治疗结直肠癌肝转移(CRLM)的疗效比较。方法:回顾自2010-2016年的329例CRLM患者临床资料,经倾向性评分匹配,共分析75例手术切除治疗与75例微波消融治疗的术后并发症、局部肿瘤进展率、无病生存率、总生存率。结果:中位随访期为42月(范围14～72月)。对肝内单发病灶(直径≤3 cm)和肝内多发病灶(n≤3,直径≤3 cm)的患者,局部肿瘤进展率、总生存率在切除组与消融组间没有显著差异(P=0.355,P=0.503)。对肝内多发病灶(n≤3,直径>3 cm)和肝内多发病灶(n>3)者,局部肿瘤进展率消融组高于手术切除组(P=0.033),总生存率消融组少于切除组(P=0.042)。结论:手术切除治疗结直肠癌肝转移优于微波消融。但对于肝内单发病灶(直径≤3 cm)和肝内多发病灶(n≤3,直径≤3 cm)的CRLM患者,微波消融可以达到与手术切除相媲美的治疗效果。     

射频消融与手术切除治疗肝癌的疗效比较

目的比较肝癌射频消融(radiofrequency ablation,RFA)与手术切除的临床治疗效果。方法回顾分析305例临床诊断为原发性肝癌患者的临床资料,根据手术方式分为射频消融组161例,手术切除组144例,根据随访结果,分析其生存情况。结果本研究结束后,肿瘤最大径≤3 cm的射频消融组与手术切除组1、2、3年生存率分别为91.0%、81.8%、63.6%和86.2%、75.9%、62.1%;肿瘤最大径4～5 cm的射频消融组和手术切除组1、2、3年生存率86.0%、68.0%、52.1%和89.6%、70.8%、60.4%;肿瘤最大径6～10 cm的射频消融组和手术切除组1、2、3年生存率69.7%、57.6%、21.1%和78.6%、60.7%、30.4%。肿瘤最大径>10 cm的射频消融组与手术切除组1、2、3年生存率分别为22.2%、11.1%、0.0%和27.3%、18.2%、9.1%。结论肿瘤直径≤3 cm,射频消融可达到手术切除的根治性治疗;肿瘤直径4～5 cm,射频消融与手术切除疗效相近;肿瘤直径6～10 cm,手术切除优于射频消融治疗;肿瘤直径>10 cm两种治疗效果都不佳。肝癌射频消融对患者创伤小、并发症少、重复性好、风险小,在肝癌治疗中有重要的应用价值。     

微波消融联合化疗治疗恶性肿瘤的研究进展

微波消融主要适用于不适合手术治疗包括不能手术切除、手术切除困难或不能耐受手术的早期肝癌患者,且无血管、肝胆癌栓或肝外转移灶,肿瘤距肝门部或胃肠道的距离至少5 cm。近年来研究表明,微波消融联合化疗对不可切除的实体瘤有着确切疗效,不良反应小,能够显著降低微波消融后局部复发率。现对有关微波消融联合化疗在恶性肿瘤治疗方面的研究进展予以综述。     

应重视小肝癌的诊断与治疗

原发性小肝癌目前国际上尚无统一的诊断标准,多数文献将小肝癌定义为单个或者相邻两个肿瘤结节直径和≤5cm,但也有相当一部分文献以肿瘤直径≤3cm作为界限。大量临床实践证明,积极治疗的小肝癌患者预后与大肝癌截然不同。小肝癌的诊断有一定困难,且多为临床早期,在治疗上存在较大的灵活性。根治性切除、局部切除、肝动脉插管化疗栓塞（TACE）、无水酒精注射（PEIT）、射频消融（RFA）、微波热凝（PMCT）、冷冻治疗等微创手术在小肝癌的治疗方面都显示其广阔的应用前景。     

经皮射频消融与手术切除治疗直径≤ 3 cm原发性小肝癌的疗效分析

目的 分析经皮射频消融（PRFA）与手术切除治疗直径≤3 cm原发性小肝癌的疗效。方法 选取2015年1月—2017年6月兰州市第二人民医院收治的原发性小肝癌患者78例。将36例接受PRFA治疗的患者作为观察组,另外42例行手术切除的患者作为对照组。采用全自动生化分析仪检测血清谷草转氨酶（AST）、谷丙转氨酶（ALT）、总胆红素（TBIL）水平,电化学发光全自动免疫分析仪检测血清甲胎蛋白（AFP）水平。结果 观察组手术时间、术中出血量、住院时间均少于对照组（P <0.05）;观察组治疗前后AST、ALT、TBIL、AFP的差值均高于对照组组（P <0.05）。两组术后并发症比较,差异无统计学意义（P>0.05）;两组治疗后1、2、3、5年的生存率和复发率比较,差异均无统计学意义（P>0.05）。结论 与手术切除比较,PRFA治疗直径≤3 cm原发性小肝癌可缩短手术时间,减少术中出血量,促进肝功能恢复,但两者术后并发症发生率、生存率和复发率接近。     

缺氧诱导因子-1α和血管内皮生长因子在肝动脉栓塞化学治疗后肝癌患者预后评估中的价值

目的探讨血清缺氧诱导因子-1α(HIF-1α)与血管内皮生长因子(VEGF)水平对肝动脉栓塞化学治疗(TACE)后肝癌患者预后评估的指导意义。方法选取2013年4月至2015年4月黄冈市中心医院收治的肝癌患者80例(TACE组),所有患者行TACE;另外选择同期体检健康者20例作为对照组。分别于TACE治疗前及治疗后1 d、1周和1个月采用酶联免疫吸附试验测定血清HIF-1α和VEGF水平;比较2组受试者血清HIF-1α和VEGF水平,并对血清HIF-1α和VEGF水平与肝癌相关参数的关系进行分析。结果治疗前TACE组患者血清HIF-1α和VEGF水平显著高于对照组(P<0.01)。TACE组患者治疗后1 d、1周时血清HIF-1α水平显著高于治疗前(P<0.01);TACE组患者治疗后1个月血清HIF-1α水平显著低于治疗前(P<0.01)。TACE组患者治疗后1个月时血清VEGF水平显著低于治疗前(P<0.01)。肝癌患者TACE治疗后血清HIF-1α和VEGF水平与Child-Pugh分级、Karnofsky评分以及巴塞罗那临床肝癌分级有显著相关性(P<0.01,P<0.05),但与甲胎蛋白水平及肿瘤大小无显著相关性(P>0.05)。结论监测血清HIF-1α和VEGF水平对TACE治疗后肝癌患者预后评估有重要意义。     

困难部位肝癌的微波消融治疗

肝癌的消融治疗日趋成熟。微波治疗是肿瘤消融的一种重要方法。微波消融在治疗小肝癌的1、3、5年生存率与手术切除治疗比较并无统计学差异。且微波消融对困难部位小肝癌治疗更具优越性,对于肝脏疑难结节的处理同样体现微创、准确、彻底的优点。另外,微波消融在其他脏器部位的应用,如肝血管瘤及脾脏肿瘤、脾功能亢进的治疗上也进入探索治疗阶段。     

TACE联合微波消融加索拉菲尼治疗中晚期原发性肝癌的临床疗效分析

Value of D-Dimers in patients with acute aortic dissection

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P ＜ 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (＞0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P ＜0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P ＜ 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.     

Research of combined liver-kidney transplantation model in rats

Objective： To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods： SD rats served as both donors and recipients. 4℃ sodium lactate Ringer＇s was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava （IVC） inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results： Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion： This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.     

Development on Adjustable Calibration Marker for Shock Wave Focus

Shock wave lithotripsy （SWL） is a treatment of choice for upper urinary stones. However, this procedure is inappropriate for obese patients because the focus is often unable to reach the target owing to the limited focal distance in shock wave source. Although treating such patients in a blast path may increase the application length of shock wave source, it＇s difficult to find this path on the lithotripter monitor. For this reason, we invented an adjustable calibration marker in order to set an effective focus in the shock wave hath.     

Study on the TCM Pathogenesis of Angiopathic Complications of Type II Diabetes

Excess production of reactive oxygen species(ROS)of mitochondrion mediated by hyperglycemia is the common pathogenesis of angiopathic complications of diabetes.TCM holds that the damp from the dysfunction of spleen.kidney and liver is the causative factor of complications of diabetes.This is similar to the mechanism of Ros resulting in angiopathic complications of diabetes.When the angiopathic complications of type II diabetes mellitus(T2DM)are difierentiated as caused by turbid damp in TCM can be explained as ROS.Since the obstruction of pathogenic damp in channels and collaterals is said to be the main pathogenesis,the treating principle should be dissolving the damp to remove the obstruction.     

Leptin, Ghrelin and TNF-α before and after Hypo-caloric Traditional Chinese Diet and Auricular Acupuncture

INTRODUCTION Obesity is a complex emergent problem, which can be possibly solved not only by the diet but also by the life style and promotion of a constant physical exercise. 1, 2 No doubt careful attentions must be given to the nutritional condition of obese people, the dietary habits, the somatic build (i.e. distribution of fat mass) and the organic functions linked to formation of the fat mass. All the parameters should be constantly monitored before, during and after a diet treatment. 3, 4, 5     

BLOOD PRESSURE CHANGE WITH AGE IN SALT-SENSITIVE TEENAGERS

Objective To observe blood pressure change with age in salt-sensitive teenagers whose salt sensitivity were determined by repeated testing.Methods Salt sensitivity was determined through intravenous infusion of normal saline combined with volume-depletion by oral diuretic furosemide in 55 teenagers. After five years, salt sensitivity was re-examined and subject blood pressure was followed up. Blood pressure changes in salt-sensitive teenagers were compared to that of non-salt sensitive teenagers over five years.Results After 5 years, the repetition rate of salt sensitivity determined by intravenous saline loading is 92.7%. In teenagers with salt sensitivity on the baseline, both the systolic blood pressure increments and increment rates were much higher than non-salt sensitive teenagers (12.7±12.1 mmHg vs. 2.8±5.2 mmHg, P＜ 0.01; 12.2%± 12.0% vs. 2.5% ±4.4%, P＜ 0.001,respectively). There was a similar trend for diastolic blood pressure (8.4 ± 6.4 mmHg vs. 3.7 ± 6.4 mmHg, P = 0.052; 13.2% ±10.6 % vs. 6.8%± 10.1%, P = 0.053, respectively).Conclusions Salt sensitivity determined by intravenous saline loading showed good reproducibility. Blood pressure increments with age were much higher in salt-sensitive teenagers than non-salt sensitive teenagers, especially in terms of systolic blood pressure.
