Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.

CD151 is a member of the tetraspanin family that is implicated as a promoter of pathological or physiological angiogenesis. C-Met is expressed on a variety of cells including vascular endothelial cells (VECs) and up-regulated during angiogenesis. In this study, we investigated whether CD151 regulated migration, proliferation, tube formation and angiogenesis of human umbilical VECs (HUVECs) with activation of C-Met. Moreover, we studied whether CD151 could affect the angiogenic molecules such as nitric oxide (NO), vascular cell adhesion molecule-1 (VCAM-1) and vascular endothelial growth factor (VEGF). The expression of CD151 was determined by Western blotting. The cell proliferation assay was performed using the cell counting kit-8 (CCK-8) method and cell migration was assessed in microchemotaxis chambers by using fetal bovine serum (FBS) as the chemotactic stimulus. The angiogenic molecules were evaluated using ELISA. The NO level was detected using NO detection kit. The potential involvement of various signaling pathways was explored using relevant antibodies. We found that proliferation, migration and tube formation of HUVECs were promoted by CD151 with activation of C-Met, FAK and CDC42, while they were suppressed with CD151 knockdown by RNAi. Similarly, the levels of NO, VCAM-1 and VEGF in HUVECs were increased by CD151, but they were inhibited with CD151 knockdown by RNAi. These data suggested that CD151 could promote migration, proliferation, tube formation and angiogenesis of HUVECs, which was possibly related to the C-Met signaling pathways.

Objective: To explore the possible anti-atherosclerotic mechanisms of glucose co-transporter-2 inhibitor canagliflozin. Methods: ApoE^-/-mice fed on Western diet were randomly assigned into the model group (n=10) and the canagliflozin group (n=10). C57BL/6J mice fed on normal diet were chosen as the control group (n=10). Mice in the canagliflozin group were gavaged with canagliflozin for 14 weeks. The presence and severity of atherosclerosis were evaluated with HE and oil red O stainings in aortic root section slices. PCR assay was performed to determine the mRNA expression levels of nitric oxide synthase. Hepatic transcriptome analysis and hepatic amino acid detection were conducted using RNA-seq and targeted LC-MS, respectively. Results: HE staining and oil red O staining of the aortic root showed that AS models were successfully established in ApoE^-/-mice fed on Western diet for 14 weeks. Canagliflozin alleviated the severity of atherosclerosis in pathology. Hepatic transcriptome analysis indicated that canagliflozin impacted on amino acid metabolism, especially arginine synthesis in ApoE^-/-mice. Targeted metabolomics analysis of amino acids showed that canagliflozin reduced hepatic levels of L-serine, L-aspartic acid, tyrosine, L-hydroxyproline, and L-citrulline, but raised the hepatic level of L-arginine. Compared to the model group, the canagliflozin group exhibited higher serum arginine and nitric oxide levels as well as elevated nitric oxide mRNA expression in aortic tissues (P<0.05). Conclusion: Canagliflozin regulated the amino acid metabolism, reduced the levels of glucogenic amino acids,and promoted the synthesis of arginine in atherosclerotic mice.

Inflammatory bowel disease(IBD) is a non-specific and chronic recurrent autoimmune disease that involves the gastrointestinal tract. Clinical symptoms of intestinal bleeding, diarrhea, and weight loss threat to human health and induce colorectal cancer. The pathogenesis included living environment, genetic factors, immune cell infiltration and immune stress, weakened mucosal barrier defense and intestinal flora imbalance. At present, clinical treatment drugs mainly include aminosalicylic acid, corticosteroids, immunosuppressants, biological agents, etc., in view of the disadvantages of poor therapeutic effect and expensive price. The active ingredients of traditional Chinese medicine(TCM) in the treatment IBD have various biological activities and multiple targets such as anti-inflammatory, antibacterial, anti-tumor and immune regulation. This article summarized the application and the research progress in protecting intestinal epithelial barrier, maintaining intestinal microbial homeostasis, inhibiting causative factors, and regulating Th1/Th17/Treg balance about TCM in the treatment of IBD. The review provided new ideas for further development of the new drugs on the mechanism based on active ingredients of TCM in IBD treatment.

To establish the ultra performance liquid chromatography (UPLC) fingerprint of Dandeng Tongnao Ruanjiaonang and conduct a systemic, comprehensive quality evaluation of the drug by combining with a chemical pattern recognition method. In this study, Waters UPLC ultra-high performance liquid chromatography instrument and ACQUITY UPLCHSS T3 chromatographic colum n were employed to perform the separation with acetonitrile-0.1% formic acid aqueous solution as the mobile phase for gradient elution; and the detection wavelength was set at 256 nm to establish the UPLC fingerprint of 10 batches of Dandeng Tongnao Ruanjiaonang. Then, the further quality assessment of the drug was carried out by similarity evaluation, Cluster Analysis(CA), Principal Component Analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Finally, 77 peaks were recognised as common peaks in the fingerprint, and 15 peaks of them were identified using standard references. The similarity value of these 10 batches of drugs was all above 0.960, indicating a relatively stable quality. But minor differences were still discovered between the batches of the drug by CA and PCA. Finally, 6 common peaks were recognised as the quality makers using OPLS-DA method. The analysis method established in this study was scientific, accurate, reliable and simple; fingerprint combined with chemical pattern recognition technique can be used to systematically and comprehensively evaluate the drug quality of Dandeng Tongnao Ruanjiaonang; what's more, it could also provide a reference for the quality control of traditional Chinese medicine and its preparations at the same time.
