[Specific DNA barcodes, germplasm resources, and genetic diversity of Eleutherococcus senticosus].

Eleutherococcus senticosus is one of the Dao-di herbs in northeast China. In this study, the chloroplast genomes of three E. senticosus samples from different genuine producing areas were sequenced and then used for the screening of specific DNA barcodes.

[Identification and quality evaluation of germplasm resources of commercial Scutellaria baicalensis based on DNA barcode and HPLC].

Scutellaria baicalensis is a commonly used Chinese medicinal herb. In this study, we identified the germplasm resources of commercial S. baicalensis samples based on trnH-psbA, petA-psbJ, and ycf4-cemA sequences according to the available chloroplast genome sequencing results, and measured the content of baicalin by HPLC.

Overexpression of PnMYB2 from Panax notoginseng induces cellulose and lignin biosynthesis during cell wall formation.

Panax notoginseng PnMYB2 is a transcriptional activator of primary and secondary cell wall formation by promoting the PCW-specific gene CesA3 and key lignin biosynthetic gene CCoAOMT1, respectively. R2R3-MYB transcription factors play important roles in regulation secondary cell wall (SCW) formation. However, there are few reports on the functions of MYB transcription factors which involved in both primary cell wall (PCW) and SCW formation.

Effect of Weikangfu granule on the physiopathologic figure of precancerosis of gastric mucosa in patients of chronic gastritis with Pi-deficiency syndrome.

Objective: To study the physiopathologic basis of Weikangfu Granule (WKFG) in treating precancerosis of gastric mucosa in patients of chronic gastritis with Pi-deficiency syndrome (CG-PDS).

Methods: One hundred and fifteen patients of CG-PDS who suffered from intestinal metaplasia (IM) and atypical hyperplasia (ATHP) of gastric mucosa, were divided into two groups. The treated group (n = 61) was treated by WKFG with its ingredients modified according to the syndrome type of patients.

Study on the pathophysiologic basis of classification of 'spleen' deficiency in chronic gastritis.

Background: Most of the studies on traditional Chinese medicine (TCM) 'spleen' deficiency syndrome in the recent 30 years were conducted only on the basis of single functional index, neglecting the study on the pathophysiologic internal relationship between spleen deficiency syndrome and gastric diseases in modern medicine. But it was at the subcellular molecular biological level that we explored the pathophysiologic basis of classification of spleen deficiency in chronic gastritis by detecting the bioactive substances in gastric mucosa nuclei and mitochondria.

Methods: By means of optical microscope, scanning electron microscope (SEM), transmission electron microscopy (TEM) and histochemical staining, we conducted histopathological, subcellular ultrastructural analysis and nuclei and mitochondrial ultrastructural analysis of gastric mucosa of 188 spleen deficiency patients and of 42 voluntary blood donors.

Study on the pathological basis of classification of spleen deficiency in chronic gastritis.

Background: Spleen in Traditional Chinese Medicine (TCM) is not actually the spleen in the anatomic sense designated in western medicine because its functions basically belong to the physiological category of digestive system in modern medicine, and it represents a macroscopic concept of digestion, absorption and nutrition metabolism. Spleen deficiency syndrome refers to the clinical phenomena such as hypofunction of digestion, absorption and nutrition metabolism. By integrating TCM with modern medicine, this paper is intended to explore the pathological basis of classification of spleen deficiency in chronic gastritis.
