目的 观察丹红注射液对Ⅰ型糖尿病大鼠周围神经病变的作用.方法 40只Wistar雄性大鼠按随机数字表法分为丹红注射液组、甲钴胺组、模型组和正常组,每组10只.前3组采用链脲佐菌素腹腔注射法制备Ⅰ型糖尿病大鼠模型,并于成模后第8周末时分别按实验设计给药.至成模后第12周末时,记录各组大鼠血糖、体质量,并应用足印行走箱行足迹步态分析,应用生理记录仪行神经传导速度检测,应用免疫组化染色及HE染色检测表皮内神经纤维及周围神经组织的病理学改变.结果 与模型组相比,丹红注射液组神经传导速度增快[（62.05±5.45） m/s vs（37.72±4.06） m/s],足迹步态参数足印长、足中间三趾宽、足印宽明显改善[（22.00±0.34） mm vs（22.74±0.19） mm;（10.79±0.22） mm vs （11.49±0.14） mm;（17.50±0.16） mm vs （17.67±0.17） mm],差异均有统计学意义（P＜0.05）.模型组大鼠表皮内神经纤维染色模糊、稀疏零散、不易辨认,严重者无神经纤维显示,而丹红注射液组神经纤维走形不规则、数量减少、断断续续、稀疏零散,但较模型组明显改善.模型组大鼠神经组织严重水肿,髓鞘缺失,难以辨认,局部有空泡变性,轴索水肿,部分轴索分离、变性,而丹红注射液组神经水肿,髓鞘模糊,轴索肿胀,但较模型组明显改善.结论 丹红注射液可以预防和改善Ⅰ型糖尿病大鼠的周围神经病变.
Objective:Traditional Chinese medicine(TCM)and modern medicine have both been used in arresting malignant transformation of chronic atrophic gastritis(CAG)in China with good therapeutic effect.However,no studies have been undertaken to assess the risk of malignant transformation in CAG patients using both modern medicine and TCM features.Our study aimed to develop risk assessment models for malignant transformation of CAG combining indicators of both TCM and modern medicine.These models will facilitate early warning and control of malignant transformation of CAG from the perspective of evidence-based integrative medicine.Methods:In the proposed registry study,a total of 1000 eligible CAG patients will be recruited from four hospitals in China.A 10-year follow-up study will be conducted both on-site and off-site to track the events of malignant transformation.Frequency analysis and chi-squared tests will be used to perform the comparative analysis on the prevalence of malignant transformation events and indicators in TCM or modern medicine in different groups.A multivariate Cox proportional hazard model will be used to perform correlation analyses of malignant transformation events and factors of TCM or modern medicine.Conclusion:The proposed study has been designed with a large sample size and long follow-up period,in which wide-ranging modern medicine and TCM indicators can be gathered over the whole process of malignant transformation of CAG.Based on this study,risk assessment models for malignant transformation ofCAGmaybe constructed fromthe perspective of integrative medicine.This may provide clinicians and patients with an optimized early warning system as well as prevention strategies for malignant transformation of CAG.
