Noninvasive prenatal paternity testing by means of SNP-based targeted sequencing.

Objective: To develop a method for noninvasive prenatal paternity testing based on targeted sequencing of single nucleotide polymorphisms (SNPs).

Method: SNPs were selected based on population genetics data. Target-SNPs in cell-free DNA extracted from maternal blood (maternal cfDNA) were analyzed by targeted sequencing wherein target enrichment was based on multiplex amplification using QIAseq Targeted DNA Panels with Unique Molecular Identifiers.

Whole extracts of Radix Achyranthis Bidentatae and Radix Cyathulae promote angiogenesis in human umbilical vein endothelial cells and in zebrafish .

Although Radix Achyranthis Bidentatae (RAB) and Radix Cyathulae (RC) are from two different medicinal plants, they are both used as 'Niu-Xi', a widely used traditional Chinese medicine that is believed to stimulate menstruation and affect bone injury. Angiogenesis is actively involved in treating these illnesses. The aim of the present study was to investigate whether the whole extracts of RAB and RC possess pro-angiogenic effects.

Identification of Target Genes Involved in Wound Healing Angiogenesis of Endothelial Cells with the Treatment of a Chinese 2-Herb Formula.

Angiogenesis is vitally important in diabetic wound healing. We had previously demonstrated that a Chinese 2-herb formula (NF3) significantly stimulated angiogenesis of HUVEC in wound healing. However, the molecular mechanism has not yet been elucidated.

Enumeration and functional investigation of endothelial progenitor cells in neovascularization of diabetic foot ulcer rats with a Chinese 2-herb formula.

Backbround: We investigated the effect of a Chinese 2-herb formula (NF3) on the enumeration and angiogenic differentiation of endothelial progenitor cells (EPCs) in diabetic foot ulcer rats.

Methods: EPCs and stromal cell-derived factor-1α (SDF-1α) were quantified by flow cytometry and ELISA, respectively. In vitro angiogenesis assays included proliferation, adhesion, migration and tube formation.

Comprehensive proteomic analysis of a Chinese 2-herb formula (Astragali Radix and Rehmanniae Radix) on mature endothelial cells.

Endothelial cells are crucially involved in wound healing angiogenesis, restoring blood flow to wound tissues. Our previous study demonstrated that the Chinese 2-herb formula (NF3) possesses significant wound healing effect in diabetic foot ulcer rats with promising in vitro proangiogenic effects on human umbilical vein endothelial cells (HUVEC). Here, we present the comparative global proteome analysis of NF3-treated HUVEC in static or scratch conditions, screening the comprehensive molecular targets in governing the proangiogenic response in wound healing.

A Chinese 2-herb formula (NF3) promotes hindlimb ischemia-induced neovascularization and wound healing of diabetic rats.

Diabetic foot ulcer is closely associated with peripheral vascular disease. Enhancement of tissue oxidative stress, reduction of nitric oxide (NO) and angiogenic growth factors, and abnormal matrix metalloproteinase (MMP) activity are pathophysiological factors in post-ischemic neovascularization and diabetic wound healing. Our previous study demonstrated that the Chinese 2-herb formula, NF3, showed significant wound healing effects on diabetic foot ulcer rats.

In vitro and in vivo mechanistic study of a novel proanthocyanidin, GC-(4→8)-GCG from cocoa tea (Camellia ptilophylla) in antiangiogenesis.

Angiogenesis, the process of blood vessel formation, is critical to tumor growth. Ant-angiogenic strategies demonstrated importance in cancer therapy. Cocoa tea (Camellia ptilophylla), a naturally decaffeinated tea commonly consumed as a healthy drink in southern China, had recently been found to be a potential candidate for antiangiogenesis.

Gene expression profiling on the molecular action of danshen-gegen formula in a randomized placebo-controlled trial of postmenopausal women with hypercholesterolemia.

The Danshen-Gegen formula (DG) is a traditional Chinese herbal formula which has long been used to treat cardiovascular disease. DG was found to be a cardiovascular tonic in our recent research. However, a comprehensive investigation of the molecular mechanism of DG in cardiovascular disease has not been performed.

Molecular angiogenic events of a two-herb wound healing formula involving MAPK and Akt signaling pathways in human vascular endothelial cells.

The emergence of electric cell-substrate impedance sensing (ECIS) technology has provided new insight in advanced cell behavioral study by its nanometer sensitivity, precise electrical wounds generation, and high reproducibility that can be monitored in real time in a noninvasive way. However, little is known regarding pro-angiogenic agents in wound healing studies using endothelial cells evaluated with ECIS technology. Our previous studies showed a prominent wound healing effect of a two-herb formula (NF3) comprising of Astragali Radix and Rehmanniae Radix in a rat chronic wound model through actions including angiogenesis.

In Vivo Study on the Pharmacological Interactions between a Chinese Herbal Formula ELP and Antiresorptive Drugs to Counteract Osteoporosis.

Antiresorptive drugs, alendronate and raloxifene, are effective in lowering bone mineral density (BMD) loss in postmenopausal women. However, long-term treatment may be associated with serious side effects. Our research group has recently discovered that a Chinese herbal formula, ELP, could significantly reduce BMD loss in animal and human studies.

Synergistic interaction between Astragali Radix and Rehmanniae Radix in a Chinese herbal formula to promote diabetic wound healing.

Ethnopharmacological Relevance: Astragali Radix (AR) and Rehmanniae Radix (RR) are two traditional Chinese medicines widely used in China for treating diabetes mellitus and its complications, such as diabetic foot ulcer.

Aim Of Study: In our previous study, a herbal formula NF3 comprising AR and RR in the ratio of 2:1 was found effective in enhancing diabetic wound healing in rats through the actions of tissue regeneration, angiogenesis promotion and inflammation inhibition. The aims of the present study were to investigate the herb-herb interaction (or the possible synergistic effect) between AR and RR in NF3 to promote diabetic wound healing and to identify the principal herb in the formula by evaluating the potencies of individual AR and RR in different mechanistic studies.

The in vivo and in vitro diabetic wound healing effects of a 2-herb formula and its mechanisms of action.

Ethnopharmacological Relevance: The herbs Radix Astragali (RA) and Radix Rehmanniae (RR) have long been used in traditional Chinese Medicine and serve as the principal herbs in treating diabetic foot ulcer.

Aim Of Study: Diabetic complications, such as foot ulcer, impose major public health burdens worldwide. In our previous clinical studies, two Chinese medicine formulae F1 and F2 have achieved over 80% limb salvage.
