Intra-operative quick insulin assay to confirm complete resection of insulinomas guided by selective arterial calcium injection (SACI)

Background and aims Insulinomas are rare endocrine disorders. Pre-operatively, conventional imaging techniques often fail to localise the tumor. In addition, due to the lack of quick insulin assays, intra-operative confirmation of complete resection was impossible until recently. Materials and methods Six patients with biochemical evidence of an insulinoma underwent pre-operative localisation studies and selective arterial calcium injection (SACI). In addition, insulin was measured before surgery and every 10–15 min after resection of the tumor using a quick insulin assay. Results Pre-operative localisation studies identified the tumor correctly as follows: endosonography: three of four, magnetic resonance imaging: two of four and SACI: six of six. Tumors in the head and body were enucleated while those in the tail were resected (n = 2, each). Those three patients, in whom magnetic resonance imaging and/or endosonography could localise the tumors pre-operatively, underwent laparoscopic surgery while the remaining three patients underwent open surgery. Intra-operatively, insulin dropped to normal levels within 20 min in all cases. After a follow-up of 0.8–3 years, all patients remained biochemically cured. Conclusions Pre-operatively, SACI appears to be a very sensitive localisation technique and may be most helpful in guiding the surgeon if conventional imaging techniques fail to localise the tumor. Complete removal of an insulinoma can be reliably predicted using a quick insulin assay. This paper was presented at the 2nd Biennial Meeting of the European Society of Endocrine Surgeons (ESES), May 18–20, 2006, Krakow, Poland.     

Intravitreal injection of 0.3 ml of SF6 gas for persistent subfoveal fluid after scleral buckling for rhegmatogenous retinal detachment

Purpose  To determine the efficacy of intravitreal injection of sulphur hexafluoride (SF6) gas for reducing persistent subfoveal fluid after scleral buckling surgery for macula-off rhegmatogenous retinal detachments. Methods  We injected 0.3 ml of SF6 gas into the vitreous cavity of two eyes of two patients with persistent macular retinal detachment 3 and 5 months after successful scleral buckling. Optical coherence tomography was performed before and after surgery. Results  Subfoveal fluid was displaced peripheral to the fovea immediately after gas injection and the fluid was absorbed gradually in both eyes. Conclusions  Persistent subfoveal fluid after scleral buckling may be treated with intravitreal SF6 gas injection. The authors have no proprietary interest in any aspect of this report     

血必净注射液对急性冠脉综合征炎症递质和预后的影响

目的探讨血必净注射液对急性冠脉综合征患者炎症递质以及预后的影响。方法将2005年4月—2009年2月收入我院心内科90例患者随机分为治疗组46例和对照组44例,对照组按照常规治疗,治疗组在对照组的基础上加用血必净注射液50 mL,每日2次,治疗7 d。采用ELISA法检测IL-6、IL-10、CRP。记录患者28 d主要心血管事件发生率。结果疗程结束时治疗组IL-6、CRP明显低于对照组(P<0.05,P<0.01),IL-10高于对照组(P<0.05);治疗组心绞痛恶化率(4%)、心肌梗死发生率(2%)较对照组(18%,16%)明显降低(P均<0.05),对照组28 d病死率(14%)高于治疗组(4%),但无显著性差异。结论血必净注射液能改善急性冠脉综合征预后,其机制可能为通过调控炎症反应实现。

参附注射液对单侧输尿管梗阻大鼠肾脏肝细胞生长因子表达的影响

目的：探讨单侧输尿管梗阻后大鼠肾间质纤维化发生过程中肝细胞生长因子（HGF）的表达及中药参附注射液对其的影响。方法：采用单侧输尿管结扎（UUO）制造梗阻性肾病模型，将56只大鼠随机分为对照组（假手术组）、手术组（UUO组）和治疗组（UUO＋参附），术后7d、14d观察肾组织病理改变，应用免疫组织化学方法检测肾组织中HGF的表达。结果：与对照组相比，手术组肾间质出现了明显的纤维化，HGF的表达在术后第7天明显增加，第14天较第7天减弱，与手术组相比，治疗组肾间质纤维化明显减轻，而且HGF的表达在术后第7天明显上调，第14天较第7天上调更明显，有统计学差异（P〈0．05）。结论：参附注射液可以上调肾组织HGF的表达，减轻肾小管一间质纤维化，发挥肾保护作用。

蟾酥注射液对小鼠S180和人结肠癌HT-29裸鼠移植性肿瘤的影响

目的研究蟾酥注射液对小鼠移植性肿瘤 S180和人结肠癌 HT-29裸鼠移植性肿瘤的抑制作用.方法分别用小鼠 S180和人结肠癌 HT-29裸鼠两种荷瘤小鼠模型,观察药物对上述肿瘤的抑瘤作用,并镜下观察后者细胞凋亡情况.结果与荷瘤阴性对照组比较,蟾酥注射液各剂量组对小鼠 S180抑瘤率( IR)为 19.1%～38.2%(P<0.05),呈量效关系;而对人结肠癌 HT-29裸鼠移植性肿瘤的 IR为 9.5%～15.8%(P>0.05),也呈量效关系,但差异均未见统计学意义;环磷酰胺则能显著抑制小鼠 S180和 HT-29细胞裸鼠移植性肿瘤的生长( IR分别为70.7%和 67.1%, P<0.01),镜检可见其有显著促进肿瘤细胞凋亡作用;未发现实验药物出现明显的毒副作用.结论该实验所用的蟾酥注射液,对小鼠 S180有抑制作用,而对人结肠癌 HT-29裸鼠移植性肿瘤,则作用不明显,表明不同类型的肿瘤对其敏感性不同.
