Objective To investigate the relationship between expression of retinal intercellular adhesion molecule-1 (ICAM-1) and blood-retinal barrier (BRB) rupture and therapeutic effect of intravitreous injection with triamcinolone acetonide (TA) on blood-retinal barrier rupture in rats with diabetes mellitus (DM). Methods Diabetic model of Wistar rats was induced and were divided into normal control group, DM-4-month group and DM-6-month group. Each group was subdivided into immunohistochemcial staining and BRB measurement groups. BRB measurement group was further divided into non-TA treatment group, 1-week-TA treatment group, and 2-week-TA treatment group. The rats were intravitreously injected with 5 mu;l TA. The digested retinal preparation was stained by immunohistochemcial method to observe the expression of retinal ICAM-1 and morphological changes. The mean optic density (A) value of endothelial cells was measured by image-analyzing software to quantify the expression of ICAM-1. BRB changes were measured by content test of retinal Evans blue (EB). Results In the immunohistochemcial staining groups, there was no significant positive expression of ICAM-1 in retinal capillary in control group. Compared with the control, there was significant positive expression of ICAM-1 in DM-4-month group (P＜0.001) with some morphological changes such as irregular width of capillary caliber, and there was enhanced positive expression of ICAM-1 in DM-6-month group (P＜0.001) with aggravated morphological changes and even acellular capillary. In the BRB measurement groups, there was no significant difference of EB content(P＞0.05) among control groups. The EB content in two DM groups significantly increased compared with that in the controls (Plt;0.001), and higher in DM-6-month group than that in DM-4-month group (Plt;0.01). In TA treatment groups, the EB content in all the DM groups significantly decreased (Plt;0.001) but with no significant difference among the groups(P＞0.05). EB content in DM-4-month group after 2-week treatment almost reached to normal value (P＞0.05) while was higher in the rest of TA treatment groups than that in the control group (Plt;0.05). Rectilinear correlation between A value of endothelial cells and the retinal EB content(r=－0.959)was found. Conclusion There is a positive relation between the expression of ICAM-1 and BRB rupture in retina of DM rats, and intravitreous injection with TA can effectively alleviate BRB rupture.

【摘要】 目的 探讨自制双孔导线针在腹腔镜小儿腹股沟疝手术中的应用价值。 方法 回顾性分析2006年4月-2010年6月行腹腔镜小儿腹股沟疝手术655例患儿的临床资料。单孔针手术组452例，双孔针手术组203例，将两组患儿术中、术后资料进行对比分析。 结果 单孔针组手术时间(17. 7±3. 5) min；术中出血(5. 4±1. 3) mL，住院时间(2. 5±1. 0) d发生腹壁下小血肿15例，术后复发3例；双孔针组手术时间(8. 2±2. 3) min，术中出血(1. 4±0. 3) mL，住院时间(2. 1±0. 8) d，发生腹壁下小血肿2例，术后复发1例。双孔针组的手术时间、术中出血、并发症发生率等均明显优于双孔针组(Plt;0. 05)，两组住院天数、复发率差异均无统计学意义(Pgt;0. 05)。 结论 自制双孔导线缝扎针在腹腔镜小儿腹股沟疝手术中应用能够缩短手术时间，操作安全快捷，创伤更小等优点，值得推广应用。【Abstract】 Objective To explore the clinical value of self-made diplopore suture needle in laparoscopic herniorrhaphy in children. Methods The clinical data of 655 patients who underwent laparoscopic herniorrhaphy between April 2006 and June 2010 were retrospectively analyzed. The patients were divided into the single-hole needle group (452 patients) and the diplopore needle group (203 patients), and the operative and post-operative data of the two groups were analyzed and compared. Results The operation time in the single-hole needle group was (17.7±3.5) minutes and the bleeding volume during the operation was (5.4±1.3) mL; while 15 patients suffered from small hematoma under the abdominal wall and three recurred. The operation time in the diplopore needle group was (8.2±2.3) minutes with (1.4±0.3) mL blood loss; while two patients suffered from small hematoma under the abdominal wall and one recurred. The patients in the single-hole needle group stayed in the hospital for (2.5±1.0) days, while the patients in diplopore needle group stayed for (1.4±0.3) days. The operation time, bleeding volume, rate of complications in diplopore needle group were significantly less than those in the single-hole needle group (Plt;0.05). The hospital staying days, and the recurrence rate in the two groups didn’t differ much (Pgt;0.05). Conclusion The advantages of self-made diplopore needle in laparoscopic herniorrhaphy in children include short operation time, less trauma, and simple operation; it is worth generalizing and applying.

Methods Thirty-eight children with respiratory infection combined with febrile convulsion and 42 children with single respiratory infection diagnosed between June 2009 and December 2010 were selected as the observation group and control group, respectively. Serum electrolytes and blood glucose concentration were assayed and compared between the two groups. Results The concentrations of serum sodium and chloride were (133.05 ± 1.74) mmol/L and (100.37 ± 1.79) mmol/L in the observation group, while (142.19 ± 1.85) and (104.57 ± 1.55) mmol/L in the control group; the differences between the two groups were significant (Plt;0.01). The concentrations of blood glucose were (6.93 ± 0.87) mmol/L in the observation group and (5.12 ± 0.55)mmol/L in the control group; the difference was significant (Plt;0.01). After the treatment, the serum concentrations of sodium and chloride were (140.89 ± 2.68) and (103.29 ± 1.94)mmol/L in the observation group, which were higher than those before treatment (Plt;0.01). After treatment, the blood glucose concentration was (5.31 ± 0.68）mmol/L in the observation group, which was lower than that before the treatment (Plt;0.01). Conclusion Hyponatremia, low serum chlorine and hyperglycemia occurre in the febrile convulsion in children, which should be corrected in the treatment of febrile convulsion.
