Pain and quality of life for patients with venous leg ulcers: proof of concept of the efficacy of Biatain®-Ibu, a new pain reducing wound dressing

Wound pain is a serious problem for elderly patients suffering from chronic leg ulcers, and it may lead to reduced wound healing rates and reduced quality of life. Biatain-Ibu Non-adhesive (Coloplast A/S), a new pain-reducing moist wound healing dressing containing ibuprofen was tested for pain reduction, safety, and efficacy on 10+2 patients in a single-blinded crossover study against Biatain Non-adhesive (Coloplast A/S). Pain was measured with a Numeric Box Scale before, during, and after dressing change. Quality of life was measured using the World Health Organization-5 Well-Being Index. Dressing moist wound healing properties such as absorption capacity and leakage were tested together with assessment of wound exudate and blood plasma content of ibuprofen. Use of the Biatain-Ibu foam dressing correlated with a decrease in pain intensity scores from 7 in the run-in period to approximately 2.5 in the Biatain-Ibu treatment phase. Quality of life measures were improved which together with the reduced pain could contribute to faster wound healing. The moist wound healing properties of Biatain-Ibu were similar to that of the Biatain Non-adhesive and ulcer size was reduced by 24% during the treatment period. Neither side effects nor systemic plasma concentrations of ibuprofen were observed. These data indicate that Biatain-Ibu could reduce persistent and temporary wound pain, increase Quality of life, was found safe to use, and had excellent moist wound healing properties.     

还原型谷胱甘肽联合甘草酸二铵对腹部开放伤后海水浸泡犬肝功能损伤的治疗作用

Objective To investigate effect of reduced glutathione and diammonium glycyrrhizinate on the treatment of hepatic damage in experimental dogs following open abdominal injuries coupled with seawater immersion. Methods Twenty-four dogs with open abdominal injuries were randomly divided into 3 groups: the control group (given with simple observation after 1.5 h seawater immersion); the routine treatment group (given routine care and fluid transfusion after 1.5 h seawater immersion) ; the hepatic treatment group (given routine are, fluid transfusion and hepatic treatment as well, after 1.5 h seawater immersion). Each group consisted of 8 dogs. Blood samples were taken at different time points to measure total bilirubin (TB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), prothromin time (PT), endotoxin, tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and pathological examination was also made at the same time. Results For the control group, contents of TB, ALT, AST and LDH increased significantly and survival time was less than 24 hours. Contents of TB, ALT, AST and LDH of the routine treatment group also increased significantly, but survival time of all the experimental animals was mere than 24 hours. Reduced glutathione and diammonium glycyrrhizinate could reduce the extent of lesion quite significantly 12～24 hours following open abdominal injuries. Conclusions Reduced glutathione and diammonium glycyrrhizinate seemed to have good effects on the treatment and prevention against hepatic damage induced by trauma coupled with seawater immersion. It could be used as a primary means for the treatment of such kind of hepatic damage.     

磁共振质子波谱成像(1H-MRSI) 在胶质瘤诊断中的应用

目的探讨利用磁共振波谱成像(MRSI)反映胶质瘤恶性度的价值.方法41例病理证实胶质瘤,原发39例、复发2例,行MR及MRS扫描,MRS数据经残差Z分数统计模型及LLI、Lip/Cho等指标划分肿瘤边界及不同代谢区,并结合MRI结构成像,划分出肿瘤的高代谢活性区、肿瘤浸润边界、坏死区及乏氧区.结果肿瘤浸润边界均超过MR常规图像上的肿瘤边界.Ⅱ级肿瘤高代谢活性区大部分位于肿瘤区内,但Ⅲ、Ⅳ级则大部分位于肿瘤边界;随肿瘤恶性度升高,肿瘤出现了坏死区及乏氧区.结论MRSI对确定肿瘤恶性度及划分肿瘤边界具有一定价值.
