AI Article Synopsis

  • The study focused on using fluorescence sequencing typing technology to identify the ingredients in Liuwei Dihuang pill, a type of Chinese patent medicine.
  • The researchers amplified and sequenced DNA from the plant Paeonia suffruticosa using specially designed primers, analyzing the results with GeneMarker software.
  • The psbA-trnH fluorescence labeling primer proved effective, successfully identifying three key medicinal plants in the Liuwei Dihuang pill, highlighting the reliability of this method for distinguishing raw materials in traditional Chinese medicine.

Article Abstract

In this paper, Liuwei Dihuang pill was used to study the identification of Chinese patent medicine by fluorescence sequencing typing technology. The DNA of Paeonia suffruticosa was used as template to amplify by five pair of FAM fluorescence labeling primers. Then, the amplified products were sequenced. The sequencing results were analyzed by GeneMarker V1.80 to screen the best fluorescence labeling primers. As a result, psbA-trnH fluorescence labeling primer was used to identify the raw materials of Liuwei Dihuang pill. The results showed that three kinds of raw plant medicinal materials in Liuwei Dihuang pill were able to be correctly identified by psbA-trnH fluorescence labeling primer. The fluorescence sequencing typing technology can stably and accurately distinguish raw medicinal materials in Chinese patent medicine.

Traditional Chinese medicine(TCM) has significant advantages in treatment of chronic kidney disease, but its clinical research evidence needs to be further summarized and improved. By means of evidence mapping, this paper systematically categorized the clinical research on TCM in treating chronic kidney disease in recent ten years, so as to understand the existing evidence level in this field and offer a reference for addressing current issues. The relevant literature published between January 1, 2013 and December 31, 2023 was systematically searched in both Chinese and English databases.

A collection of chronic central motor, postural, and activity restriction symptoms are referred to as cerebral palsy (CP). Previous research suggests that a number of perinatal variables, including hypoxia, may be linked to CP. And the pathophysiological process that causes brain injury in growing fetuses is mostly caused by amniotic fluid infection and intra-amniotic inflammation.

Objective: To evaluate the anti-tumor effector of Liuwei Dihuang Decoction (LWDHD) in prostate cancer (PCa) and explore the potential mechanism using experimental validation, network pharmacology, bioinformatics analysis, and molecular docking.

Methods: CCK test, Clone formation assay and wound-healing assays were used to determine the effect of LWDHD on prostate cancer growth and metastasis. The active ingredients and targets of LWDHD were obtained from the TCMSP database, and the relevant targets were selected by GeneCards, OMIM and DisGeNET databases for PCa.

Background: Intervertebral disc (IVD) degeneration (IVDD) is highly prevalent among the elderly population and stands as a leading cause of low back pain. Our prior studies have highlighted the therapeutic potential of Liuwei Dihuang decoction (LWDHD) and its component (CO)-derived compounds in alleviating IVDD and osteoarthritis, suggesting beneficial effects of CO in treating degenerative osteoarthropathies. However, uncertainty remains regarding the optimal CO dosage within LWDHD and its potential mechanism for effectively treating IVDD.
