溶瘤腺病毒治疗肾癌的研究进展

我国肾癌发病率逐年上升。早期肾癌有治愈的可能，但晚期或转移性肾癌的治疗仍是一大难题。溶瘤腺病毒作为一种新型抗肿瘤制剂，具有选择性复制并杀伤肿瘤细胞的特点。近年来研究发现，溶瘤腺病毒对肾癌具有良好的抗肿瘤效果及安全性，联合放化疗治疗可以进一步提高疗效。以溶瘤腺病毒为载体的肾癌基因治疗也有广阔的应用前景。     

层面递进法激光腔内剜除高危前列腺增生的治疗体会

目的探讨1 470 nm激光剜除治疗高危前列腺增生的手术技巧及临床效果。 方法回顾分析2018年6月至2018年9月中山大学附属第三医院泌尿外科采用1 470 nm激光治疗共89例高危前列腺增生患者的临床资料，年龄平均（68±3）岁，前列腺体积（57.4±2.6）ml。所有患者均采用"寻找层面，先易后难，剜切结合"的层面递进法思路行激光腔内前列腺剜除术，比较患者术中及术后情况。 结果89例均顺利完成手术，与术前相比，术后3个月患者最大尿流率明显增加，[（6.9±2.1） ml/s vs（19.8±3.6） ml/s]。国际前列腺症状评分显著好转，[（24.6±1.7） vs（8.0±1.2）]。术中无输血、无电切综合征、无直肠和膀胱穿孔病例，无输尿管损伤、大出血、心脑血管意外等严重并发症发生。 结论层面递进法激光剜除技术构想对于高危前列腺增生外科包膜层面的寻找、减少术后并发症有独到优势，且易于掌握，或可为业界同行提供一个新的思路。

残胃癌的外科治疗(附26例临床分析)

多数学者认为 :残胃癌是指胃、十二指肠良性病变行胃大部切除术后或胃空肠吻合术等手术 5年以上残胃发生的癌[1] 。对于发生于胃癌术后的是否属于残胃癌 ,其时间间隔应为多少 ,仍有很大争议。我院自 1980年至 2 0 0 0年间共收残胃癌 2 6例 (同期收住的 11例胃癌术后出现的残胃癌未包括其内 ) ,现将 2 6例残胃癌的临床特点报告如下 :1　临床资料1)　一般资料 :本组残胃癌 2 6例 ,男 2 4例 ,女2例 ,年龄 38～ 76岁 ,平均年龄 5 9.3岁 ,男女比例为 12∶1,确诊前症状持续平均时间为 6 .8个月 ,5 0岁以上占 84 .6 % (2 2 / 2 4 )。吞咽不畅 8例(3…     

环戊硫酮治疗干眼的临床疗效评价

Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value.     

脂多糖直接诱导对肺微血管内皮细胞IL-8表达的影响及通过NF-κΒ调控机理的研究

目的　探讨脂多糖 (LPS)的直接诱导作用对肺微血管内皮细胞 (PMVEC)IL 8表达的影响及通过核因子κB(NF κB)的调控机理。方法　以 10 0ng/mlLPS刺激PMVEC 0 ,0 .5 ,1,2 ,4,6,8h或 1ng/ml、10ng/ml、10 0ng/mlLPS刺激 1h或6h为检测时相点 ,ELISA、原位杂交试验分别检测的培养液上清中分泌的IL 8及PMVEC内IL 8mRNA的表达 ;凝胶电泳迁移率分析 (EMSA)检验NF κΒ的活化 ;并观察NF κΒ活化抑制对IL 8表达的影响。结果　LPS能显著促进PMVEC表达IL 8,包括促进IL 8mRNA的表达及IL 8的分泌。在时间上mRNA的表达先于IL 8分泌。且LPS的直接诱导能迅速活化NF κΒ ,1h达到高峰 ,后逐渐下降。PDTC能显著抑制NF κΒ的活化及IL 8的表达 (P <0 .0 1)。结论　表明细菌致病因子LPS的直接诱导确能通过促进NF κΒ的活化 ,从而启动IL 8的高效表达和分泌 ,为多形核中性粒细胞 (PMN)的迁移提供必需的物质条件 ,导致肺损伤。
