八宝丹配合介入治疗热毒血瘀型原发性肝癌的临床观察

目的:初步观察八宝丹辅助治疗热毒血瘀原发性肝癌的临床疗效。方法:入选病人随机进入临床观察,一组单纯介入治疗;一组患者在介入基础上口服八宝丹,2粒/次,3次/日连续服用8周为1个周期。介入用药统一为5-FUDR1.0 DDP 60~80mg E-ADM60~80mg 碘油5~10mL,1次/4周共2次。观察八宝丹对患者近期中医证候、客观疗效及毒副反应的影响和1年生存率。结果:两组患者治疗后肿瘤大小、甲胎蛋白浓度比治疗前都有很大程度的缩小或降低。八宝丹联合介入治疗组中医证候的改善明显优于单纯介入治疗组,二者证候稳定改善率分别为85%、55%;单纯介入组患者出现腹痛、呕吐、或体温超过38℃的并发症情况多于八宝丹联合介入治疗组患者。两组比较差别显著P<0.05。单纯介入组患者肝功能损害也明显多于八宝丹联合介入组患者。单纯介入组患者1年生存率48.3%,显著低于八宝丹联合介入组患者61.8%,P<0.05。结论:八宝丹在改善热毒血瘀肝癌患者中医证候,减少、降低介入治疗并发症,延长生存时间有很好的治疗作用;值得进一步研究其在临床治疗肝癌的有效性。     

Traditional Chinese medicine for prevention and treatment of hepatocellular carcinoma: A focus on epithelial-mesenchymal transition

Hepatocellular carcinoma (HCC) is one of the most prevalent malignant cancers worldwide. Epithelial-mesenchymal transition (EMT), which endows epithelial cells with mesenchymal properties, plays an important role in the early stages of metastasis. Conventional cancer therapies have promising effects, but issues remain, such as high rates of metastasis and drug resistance. Thus, exploring and evaluating new therapies is an urgent need. Traditional Chinese medicines (TCMs) have been acknowledged for their multi-target and coordinated intervention effects against HCC. Accumulating evidence indicates that TCM can inhibit the malignancy of cells and the progression of EMT in HCC. However, studies on the effects of TCM on EMT in HCC are scarce. In this review, we summarized recent developments in anti-EMT TCMs and formulae, focusing on their underlying pharmacological mechanisms, to provide a foundation for further research on the exact mechanisms through which TCM affects EMT in HCC.     

防感煎剂对H1N1病毒感染小鼠TNF-α、IL-6的影响

目的探讨防感煎剂对H1N1流感病毒感染小鼠TNF-α、IL-6的影响,进一步了解防感煎剂的疗效机理。方法选用清洁级ICR雄性小鼠96只,随机分为4组：正常对照组、模型对照组、防感煎剂组、达菲对照组。实验组予防感煎剂灌胃给药,达菲对照组予达菲灌胃给药,正常对照组和模型对照组则用生理盐水灌胃,在灌胃给药第3天开始用H1N1流感病毒液滴鼻造模,造模后的第1、5、9、13天每组随机处死6只小鼠,收集肺组织标本,用于H1N1病毒核酸提取,收集血清,用ELISA法检测肿瘤坏死因子a（TNF-α）、白细胞介素6（IL-6）含量。结果1、防感煎剂组小鼠一般状况优于模型组。2、防感煎剂组小鼠肺组织H1N1病毒含量低于模型组（P〈0．05）。3、防感煎剂组小鼠血清TNF-α、IL-6水平低于模型组（P〈0．01）。结论防感煎剂可抑制H1NI病毒复制,抑制细胞因子TNF-α、IL-6的表达,从而减轻由炎性介质过度释放引起的免疫病理损伤,由此推断防感煎剂可能通过调节免疫功能来控制感染、改善症状。     

浙江地区小儿性早熟的病因分析及证候分布研究

目的分析浙江地区小儿性早熟的病因及证候分布。方法采用调查表临床研究的方法共调查儿童192例,经Spearman检验对调查问卷进行统计分析。结果性早熟的患儿中女童占95.8%,男童占4.2%。性早熟的发病情况与食用牛初乳、蜂皇浆、蚕蛹等有相关性;与父母青春期发育情况、患儿出生时情况、饮食习惯、生活习惯等多种因素无相关性。186例性早熟儿童中136例属于肾虚火旺型(占73.12%),36例为肝经郁热型(占19.35%),14例为痰湿阻滞型(占7.53%)。结论性早熟以女童多见,病因学分析显示本病发病与使用牛初乳、蜂皇浆、蚕蛹等有相关性,临床中以肾虚火旺型为常见。     

清热消积方对人肺腺癌细胞A549 VEGF及MMP-2表达的影响

目的：研究清热消积方对体外培养的人肺腺癌细胞A549 VEGF及MMP-2表达的影响。方法：将不同浓度清热消积方与人肺腺癌细胞A549作用,用Elisa法检测清热消积方对VEGF及MMP-2蛋白表达水平的影响;PCR法检测清热消积方对VEGF和MMP-2的mRNA水平的影响。结果：高、中浓度组清热消积方及清热消积方-5-FU联用组能够明显抑制VEGF及MMP-2蛋白表达,且对VEGF和MMP-2的mRNA水平有抑制作用,呈现一定的剂量依赖性。结论：清热消积方可抑制人肺腺癌细胞A549 VEGF及MMP-2生成,可能是其抗肿瘤血管形成效应的机制之一。     

Stevens-Johnson syndrome/toxic epidermal necrolysis successfully treated with Chinese herbal medicine Pi-Yan-Ning: A case report

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare adverse cutaneous reaction with a low incidence and high mortality. Despite posing a serious threat to patients’ health and lives, there is no high-quality evidence for a standard treatment regimen. Here we report the case of a 62-year-old man with stage IV pancreatic cancer who experienced immunotherapy-induced SJS/TEN. After consensus-based regular treatments at a local hospital, his symptoms became worse. Thus, he consented to receive Chinese herbal medicine (CHM) therapy. The affected parts of the patient were treated with the CHM Pi-Yan-Ning which was applied externally for 20 min twice a day. After 7 days of treatment, the dead skin began peeling away from the former lesions that had covered his hands, feet, and lips, indicating that skin had regenerated. After 12 days of treatment, the patient’s skin was completely recovered. In this case, SJS/TEN was successfully treated with Pi-Yan-Ning, suggesting that there might be tremendous potential for the use of Pi-Yan-Ning in the treatment of severe skin reactions to drug treatments. Further basic investigations and clinical trials to explore the mechanism and efficacy are needed.
