Inhibitory Effect of Polysaccharide on Premetastatic Niche of Lung Cancer through the S1PR1-STAT3 Signaling Pathway.

As a common malignant tumor, the morbidity and mortality of lung cancer have been rising in recent years. The concept of "premetastatic niche" may lead to a revolutionary change in antitumor metastasis therapeutic strategies. Traditional Chinese medicine with multitargets and lower poisonous agents may be a potentially effective means to intervene in the "premetastatic niche (PMN)" to prevent and treat tumor metastasis.

Total flavonoids of Oxytropis falcata Bunge have a positive effect on idiopathic pulmonary fibrosis by inhibiting the TGF-β1/Smad signaling pathway.

Ethnopharmacological Relevance: Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease with unknown etiology. Oxytropis falcata Bunge (O. falcata) is a 1-35 cm high perennial clustered herb, also known as edaxia, has viscosity and a special smell, and is mainly distributed in the western areas of China.

Effect of Total Flavonoids of Bunge on the Expression of p-JAK1-and p-STAT1-Related Proteins in Idiopathic Pulmonary Fibrosis.

Objective: The study aimed to explore the effect of total flavonoids of Bunge (FOFB) on the expression of p-JAK1/p-STAT1 and SOCS3 proteins in idiopathic pulmonary fibrosis (IPF).

Methods: Rats model with IPF was established by one-off intratracheal injection of bleomycin (BLM, 5 mg/kg). After 14 days, the same volume of low dose (100 mg/kg), medium dose (200 mg/kg), and high dose (400 mg/kg) of FOFB and prednisolone acetate (20 mg/kg) as positive control drugs, as well as normal saline, were orally administered to rats once a day for 28 consecutive days.

[Effects of Banxia Xiexin Decoction Containing Serum on Proliferation, Invasion and Metastasis of Gastric Cancer Peritoneal Metastasis Cell Line GC9811-P].

Objective To observe the effects of Banxia Xiexin Decoction (BXD) containing ser- um on proliferation, invasion and metastasis of in vitro human gastric cancer peritoneum cell strain GC9811-P (which has high metastatic potential). Methods BXD containing serum was prepared. GC9811-P cells were inoculated in the E-Plate 96 and CIM Plate 16, and then 0, 25, 50, 100 μL/mL BXD containing serums were added respectively.

Intervention effect of pinelliae decoction for purging stomach-fire on malignant transformation of bone marrow mesenchymal stem cells in the gastric cancer microenvironment.

Objective: The study aimed to simulate the microenvironment of gastric cancer to promote the malignant transformation of bone marrow mesenchymal stem cells (BMSCs) and further evaluate the effect of Pinelliae Decoction for Purging Stomach-Fire and its disassembled prescriptions on BMSCs.

Methods: Transwell co-culture was performed on the human gastric cancer cell strains BGC-823 and BMSCs to simulate the microenvironment of gastric cancer. The drug-containing serum prepared by Pinelliae Decoction for Purging Stomach-Fire and its disassembled prescriptions was used, and its influence on BMSCs with malignant transformation was observed.

Sodium tanshinone IIA sulfonate attenuates radiation-induced fibrosis damage in cardiac fibroblasts.

The main pathological change in radiation-induced heart disease is fibrosis. Emerging evidence has indicated that sodium tanshinone IIA sulfonate (STS) was used for treating fibrosis diseases. The present study was undertaken to characterize the effect of STS on radiation-induced cardiac fibrosis (RICF) on cultured cardiac fibroblasts (CFs).

[Influence of single leaf Asarum himalaicum on renal function of rabbits].

Objective: To study the influence of single leaf Asarum himalaicum on the renal function of rabbits.

Methods: Rabbits were divided into three groups. Asarum himalaicum, Asarum heterotropoides and normal saline were intravenously administered to the rabbits of one group respectively.
