Effect of topical propranolol gel on plasma renin, angiotensin II and vascular endothelial growth factor in superficial infantile hemangiomas.

The effect of topical propranolol gel on the levels of plasma renin, angiotensin II (ATII) and vascular endothelial growth factor (VEGF) in superficial infantile hemangiomas (IHs) was investigated. Thirty-three consecutive children with superficial IHs were observed pre-treatment, 1 and 3 months after application of topical propranolol gel for the levels of plasma renin, ATII and VEGF in Department of General Surgery of Dongfang Hospital from February 2013 to February 2014. The plasma results of IHs were compared with those of 30 healthy infants of the same age from out-patient department.

[Effect of propranolol gel on infantile hemangiomas].

Objective: To evaluate the efficacy and security of propranolol gel in treatment of Infantile hemangiomas.

Methods: 51 consecutive infants with hemangiomas from October 2010 to September 2011 in Department of General Surgery Fuzhou General Hospital of Nanjing Military Command were treated with propranolol hydrochloride 3% gel. Changes in hemangioma size, texture, color, tumor blood flow peak were recorded.

Single purse string with four-point traction for better haemorrhoid retraction.

Background: Traction method is important to stapled haemorrhoidopexy (SH) for its impact on haemorrhoidal prolapse reduction. Single purse string with one-point traction is most commonly used in SH. This traction method often results in an irregular mucosal doughnut with inadequate height, which leads to insignificant and uneven haemorrhoidal prolapse reduction.

[Protective effect of N-acetylcysteine on the intestinal barrier dysfunction after radiation injury in rats].

Objective: To evaluate the protective effect of N-acetylcysteine (NAC) on the intestinal barrier dysfunction in rats after extensive abdominal radiation with X ray.

Methods: Twenty-four Spraque-Dawley male rats were divided into normal control group (n=8), radiation group (n=8), and radiation+NAC group (300 mg/kg) (n=8). Radiation injury was induced by X ray with a single dose of 10 Gy.
