The rapid,complete,targeted and safe treatment for tumors remains a key issue in cancer therapy.A novel treatment of solid tumors by supramolecular photocatalyst Nano-SA-TCPP with the irradiation of 600-700 nm wavelength is established.Solid tumors (100 mm3) can be eliminated within 10 min.The S0-day mouse survival rate was increased from 0％ to 100％ after the photocatalytic therapy.The breakthrough was owing to the cell membrane rupture and the cytoplasmic loss caused by photogenerated holes inside cancer cells.The porphyrin-based photocatalysts can be internalized in a targeted manner by cancer cells due to the size selection effect,without entering the normal cells.The therapy has no toxicity or side effects for normal cells and organisms.Moreover,the photocatalytic therapy is effective for a variety of cancer cell lines.Because of its high efficiency,safety and universality,the photocatalytic therapy provides us with a new lancet to conquer the tumor.

目的探讨基于“学习通”线上线下教学在血液内科见习中的实施与研究。方法随机选取广西医科大学2019~2020学年下学期2016级五年制临床医学本科一个班为观察组,选取2018~2019学年下学期2015级的一个班级为对照组。观察组采用基于“学习通”平台线上线下结合的教学模式,对照组采用传统的病房实地见习模式,观察并比较两组学生在血液内科见习的教学效果。结果观察组学生的测试成绩及病历书写能力均明显高于对照组,差异有统计学意义(均P<0.05)。结论基于“学习通”线上线下相结合的教学模式应用于血液内科见习
采用UPLC-Q-TOF/MS研究岩黄连水提物在大鼠体内的主要代谢产物,利用质量亏损过滤(MDF)进行分析,鉴定大鼠灌胃岩黄连水提物后血浆、尿液、胆汁、粪便中的代谢产物。岩黄连水提物中脱氢卡维丁、巴马汀及小檗碱在大鼠不同代谢途径中推测出原型、羟基化、去甲基化、还原、去甲基化葡萄糖醛酸化与硫酸结合等多个代谢产物。
中药药剂学作为中药学专业的主干课程,由于知识点分散、内容抽象,学生很难全面理解和掌握。为更好地满足教学需求,迎合现代教学趋势,进一步提升教学质量,在中药药剂学教学中采用BOPPPS模式进行教学,并分析BOPPPS模式的实施优势,探讨实施的具体途径以及实施过程中可能出现的相关问题。

目的建立桃核承气汤的HPLC指纹图谱,并研究其与抗炎药效的谱效关系。方法采用HPLC建立15批桃核承气汤的指纹图谱,并进行药效试验,以TNF-α的抑制率和IL-10的促进率为抗炎作用的药效指标,使用灰色关联度分析法构建谱效关系。结果建立了桃核承气HPLC指纹图谱,确定了22共有峰并指认了其中9个色谱峰。药效试验结果显示,各批次桃核承气汤均具有一定的抗炎作用。经灰色关联度分析可知,除2号峰外各共有峰与2个抗炎药效指标的关联度均>0.6,其中4、10(大黄酸-8-O-β-D葡萄糖苷)、16、21(甘草酸
