Chemotherapy in alveolar echinococcosis of multi-organs: what’s the role?

The aim of this study was to investigate the clinical efficiency of chemotherapy for the treatment of human alveolar echinococcosis (AE). Twenty-four patients who suffered from late-stage AE were enrolled in this study. The classification of the disease stages was performed according to the PNM (parasite lesion, neighboring organ invasion, metastases) classification system established by the World Health Organization Informal Working Group on Echinococcosis and classification standards. Radical surgery (n?=?3), palliative surgery plus chemotherapy (n?=?11), and sole chemotherapy (n?=?10) were given, respectively. For those with AE metastasis with spleen and kidney, radical surgery was effective for the treatment. However, the treatment efficiency for those with AE metastasis to bone tissues was unfavorable. Significant improvement was noted in those with cerebral lesions after chemotherapy. Stable health conditions were observed in those with pulmonary lesions after chemotherapy. For those with liver lesion, long stable health conditions were noted after chemotherapy. However, surgical interventions were needed as the occurrence of bile duct complications. With regards to the other lesions, radical surgeries were recommended. Satisfactory treatment outcomes were obtained in those with AE after chemotherapy.     

天水医事简略

天水地处甘肃东南部,历史悠久,医疗卫生源远流长,名家辈出,由于古时兵乱灾疫较多,加之造纸术,印刷术落后,使得众多珍贵文献难以保存至今,本文就笔者研习所得做一简要阐述。

Rapid analysis of piperazine ferulate tablets by optic-fiber sensing technology and the similarity of ultraviolet spectra

A rapid analysis method of piperazine ferulate tablets by optic-fiber sensing technology with UV–vis absorption spectrum was established. Qualitative and quantitative data were obtained and compared by maximum and minimum wavelength, absorbance and contrast spectra. Similarity method was used to identify authenticity of drugs. The difference of contents measured by this method and UV determination method in China Pharmacopoeia showed no statistical significance (P>0.05), while the similarity can be used as a parameter to identify the authenticity of drugs.     

仓鼠深Ⅱ度烧伤创面愈合过程中糜蛋白酶的表达

背景：肥大细胞糜蛋白酶在烧伤创面表达的研究较少。 目的：观察肥大细胞糜蛋白酶是否存在于烫伤创面以及深Ⅱ度烫伤后不同时间点的表达变化。 方法：应用75 ℃的水接触仓鼠背部皮肤12 s制备深Ⅱ度烫伤创面(病理组织学证实)。分别于烫伤前及烫伤后1，3，7，14 d取烫伤组织进行试验。 结果与结论：实时定量RT-PCR及放射免疫 检测结果显示烫伤后创面组织中糜蛋白酶mRNA表达量和活性均有所增高，在烫伤后第3天最高。表明肥大细胞糜蛋白酶在烧伤创面有所表达，并可能参与了烧伤损伤愈合过程。     

维吾尔医学异常黏液质证载体模型大鼠血清代谢组学研究

目的：利用磁共振(magnetic resonance,MR)测定技术探讨异常黏液质证载体模型大鼠血清代谢组分的变 化及其与异常黏液质证的关系。方法：将Wistar大鼠(雄性)随机分为正常对照组和异常黏液质证载体模型组,以湿 寒饲料(芫荽实和菠菜实)和环境[温度(6±1) ℃,相对湿度85%~95%]进行干预,建立异常黏液质证载体模型,并进行 鉴定,收集各组大鼠血清,进行磁共振氢谱(1H MR)测定,运用正交偏最小二乘判别(OPLS-DA)分析所采集的图谱, 确认差异性代谢组分。结果：与正常组相比,异常黏液质证载体模型大鼠血清中谷氨酸、苯丙氨酸、酪氨酸、柠檬 酸、β-羟丁酸、乙酰乙酸、丙酮酸和肌酸等代谢组分含量降低,而α-葡萄糖、β-葡萄糖、乳酸、低密度脂蛋白(LDL) 和极低密度脂蛋白(VLDL)等代谢组分的含量升高,差异有统计学意义(P<0.05)。结论：异常黏液质证载体模型大鼠三 大营养物质分解代谢出现障碍,并处于产能和耗能均较低的状态,三大营养物质及能量代谢障碍可能是异常黏液质 证的分子基础。
