改良小梁切除术治疗伴有高眼压及大瞳孔的急性房角关闭

目的 评价改良小梁切除术治疗伴有高眼压及大瞳孔的急性房角关闭的临床疗效。方法收集2005年1月至2009年3月中山大学中山眼科中心青光眼专业实施改良小梁切除术治疗伴有高眼压及大瞳孔的急性房角关闭21例（21眼）的临床资料,对术后并发症及手术前后的眼压、视力、瞳孔等进行统计分析。 结果 术前眼压(48.25±3.14) mmHg,平均用降眼压药种类3.35种,明显高于出院时眼压(10.47±1.15)mmHg(t=11.4573,P＜0.01)及术后3个月眼压(13.86±0.93) mmHg(t=11.2641,P＜0.01)。出院视力(0.09±0.05)与术前视力(0.11±0.06)差异无统计学意义(沁0.8702,P= 0.3913),术后3个月视力(0.21±0.04)则稍好于术前（t=-2.7907,P=0.0112）。术前瞳孔垂直径(5.81±0.23) mm与出院时瞳孔垂直径(5.92±0.21 )mm差异无统计学意义（t=-1.5013,P=0.1672）。无严重并发症发生。 结论 改良小梁切除术是治疗伴有高眼压及大瞳孔的急性房角关闭的有效方法,术中分次放房水、巩膜瓣调节缝线、术毕形成前房等措施可有效减少严重并发症的发生。     

Roboterunterstützte hepatobiliäre Chirurgie und Magenchirurgie

Hepatobiliary surgery is a challenging surgical subspecialty that requires highly specialized training and an adequate level of experience in order to be performed safely. As a result, minimally invasive hepatobiliary surgery has been met with slower acceptance as compared to other subspecialties, with many surgeons in the field still reluctant about the approach. On the other hand, gastric surgery is a very popular field of surgery with an extensive amount of literature especially regarding open and laparoscopic surgery but not much about the robotic approach especially for oncological disease. Recent development of the robotic platform has provided a tool able to overcome many of the limitations of conventional laparoscopic hepatobiliary surgery. Augmented dexterity enabled by the endowristed movements, software filtration of the surgeon’s movements, and high-definition three-dimensional vision provided by the stereoscopic camera, allow for steady and careful dissection of the liver hilum structures, as well as prompt and precise endosuturing in cases of intraoperative bleeding. These advantages have fostered many centers to widen the indications for minimally invasive hepatobiliary and gastric surgery, with encouraging initial results. As one of the surgical groups that has performed the largest number of robot-assisted procedures worldwide, we provide a review of the state of the art in minimally invasive robot-assisted hepatobiliary and gastric surgery.

提高大鼠心肌梗死后心力衰竭模型存活率的实验研究

目的建立大鼠心肌梗死后心力衰竭模型,并进行评估,以提高存活率和成功率。方法分批对70只SD大鼠行冠状动脉左前降支结扎术,同时设15只假手术组,并计算死亡率。于4周时行血流动力学检查,检测心率(HR)、左心室舒张末压(LVEDP)、左室压力最大上升速率(+dp/dtmax)以及左室压力最大下降速率(-dp/dtmax)。结果4周时模型组HR、+dp/dtmax和-dp/dtmax绝对值均低于假手术组(P<0.05),LVEDP则高于假手术组(P<0.05)。随着手术大鼠例数增多,存活率得到提高(P<0.05)。结论心肌梗死后4周形成心力衰竭模型,通过经口气管插管法、选择结扎冠状动脉分支末梢部位、增加手术操作熟练程度,可提高动物存活率。     

26万女性队列人群中乳腺癌与人工流产关系的研究（上海）

目的：评估人工流产（指手术流产）对乳腺癌危险性的可能影响。方法：研究在上海267040例妇女的一项乳房自我检查随机试验的队列人群中进行，由队列研究和巢式病例对照研究两部分组成。结果：依据基线调查表采集的资料分析，人工流产不增加乳腺癌危险性。调整潜在的混淆因素后，OR=1．06（95％CI：0．91～1．25）。人工流产次数增加无危险性趋势增加。从更详细的652例乳腺癌病例和694例对照资料分析，得出相似的结果。人工流产发生在首次生育后不增加危险性；少数妇女在首次生育前人工流产以及妊娠13周后人工流产，虽然被观察到危险性有增加，但无显著性统计学意义。结论：在中国，人工流产不是乳腺癌发生的重要原因。     

开设综合性生理学实验课的实践与体会

生理学探索性、综合性实验有利于提高学生的系统综合和创新能力，为此，根据实验室现有条件，我们对传统实验教学进行改革，设计成为探索性综合性实验并在七年制学生中开展。该实验既与课本知识紧密结合，又与临床密切相关。实践证明，该实验使学生系统性掌握生理学知识的同时为他们临床分析解决问题奠定了基础。

Remission following an elemental diet or prednisolone in Crohn's disease

The short- and long-term effects of an elemental diet in children with acute Crohn's disease were compared with those of prednisolone in historical controls. Clinical remission was induced in 25 of 30 and in 18 of 28 episodes treated for six weeks with an elemental diet and prednisolone. Patients with proximal disease had longer remission after treatment with an elemental diet (p < 0.05) than did patients with colonic disease after treatment with prednisolone (p < 0.01). Disease activity index score improved in both groups compared with the pretreatment scores (p < 0.05). However, the improvement in the elemental diet group was significantly better than in the prednisolone group (p < 0.001). Changes in linear growth were better after treatment with an elemental diet compared with steroids (p < 0.001). Serum albumin and haematocrit concentrations all improved significantly in the children treated with an elemental diet (p < 0.001) but not in those treated with steroids. Thus an elemental diet was better than prednisolone in proximal disease and confirmed improved growth and nutritional status.     

Multivariate analyses of prognostic factors associated with hematopoietic recovery in autograft patients with different sources of progenitor cells: A GATMO experience

OBJECTIVE:: To evaluate in a multivariate analysis the prognostic factorsassociated with hematopoietic recovery and the supportive carerequirements after autotransplant of progenitor cells (PC) fromvarious sources: bone marrow (BMPC), BMPC & peripheral blood(PBPC), and PBPC alone. PATIENTS AND METHODS:: A total of 570 patients with hematological malignancies andsolid tumors underwent high-dose therapy followed by autotransplant.PBPC were obtained after mobilization with chemotherapy and/orcytokines. One-hundred five patients received BMPC, 217 receivedBMPC & PBPC and 248 PBPC alone; all of the patients receivedG-CSF or GM-CSF after infusion. RESULTS:: In a multivariate analysis the recovery of neutrophils was adverselyassociated with low numbers of nucleated cells infused (P<0.13),bone marrow progenitor cell source, and diagnosis of multiplemyeloma and acute leukemia (P<0.001). The factors that adverselyaffected platelet recovery were low number of nucleated cellsand diagnosis of multiple myeloma and acute leukemia (P<.001). CONCLUSION:: We conclude that BMPC adversely affect neutrophil recovery whilelow numbers of nucleated cells and diagnosis of multiple myelomaand acute leukemia adversely affect both neutrophil and plateletrecovery. autograft, bone marrow, hematological recovery, peripheral blood, progenitor cells, prognostic factors     

Surgical treatment of anal stenosis following hemorrhoid surgery. Results of 150 combined mucosal advancement and internal sphincterotomy

The aim of the study was to evaluate the efficacy of anoplasty by mucosal advancement combined with internal sphincterotomy for the treatment of iatrogenic anal stenosis. From January 1990 to December 2000, 149 patients with post-haemorrhoidectomy anal strictures underwent internal sphincterotomy and mucosal advancement flap anoplasty. Seventy-one percent of patients were operated on under local anaesthesia by perineal block according to Marti. In 90 percent of the patients, postoperative pain was mild. No significant complications were seen. The mean hospital stay was two days. Ninety-seven percent of patients were well satisfied with the surgical result one year after operation. Current surgical options for the treatment of post-haemorrhoidectomy anal stricture are reported and the advantages of mucosal advancement flap anoplasty outlined.
