Rhodiola rosea L., a worldwide botanical adaptogen, has been confirmed to possess protective effects of inflammatory injury for many diseases, including cardiovascular diseases, neurodegenerative diseases, diabetes, sepsis, and cancer. This paper is to review the recent clinical and experimental researches about the anti-inflammatory effects and the related mechanisms of Rhodiola rosea L.

Article Synopsis
  • Acute pancreatitis (AP) is an inflammatory condition triggered by the abnormal activation of digestive enzymes, and baicalein has shown potential anti-inflammatory properties that may help mitigate AP effects.
  • Research explored baicalein’s effects on caerulein-induced pancreatitis using both in vivo and in vitro models, revealing that baicalein reduces inflammation and tissue damage in the pancreas.
  • The study found that baicalein decreases pro-inflammatory cytokines and inhibits key signaling pathways (NF-κB, MAPK, and STAT 3), suggesting its promise as a treatment option for AP patients.

The purpose of this research was to extract and separate the compounds from frankincense, and then evaluate their anti-inflammatory effects. The isolated compound was a representative tetracyclic triterpenes of glycine structure according to ¹H-NMR and C-NMR spectra, which is β-elemonic acid (β-EA). We determined the content of six different localities of frankincense; the average content of β-EA was 41.

We investigated the beneficial effects and underlying mechanisms of Zhuanggu Guanjie (ZGGJ) pill in osteoporosis and . Bone marrow macrophages from 4-6-week-old mice were cultured in the presence of macrophage colony-stimulating factor (15 ng/mL) and receptor activator of nuclear factor-B ligand (30 ng/mL). Osteoclast differentiation was determined by quantification of tartrate-resistant acid phosphatase activity.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive cancers. Recent research has demonstrated that chronic pancreatitis (CP) is associated with an increased risk of PDAC, partly due to acinar-to-ductal metaplasia (ADM). Baicalein has been shown to exert anti-inflammatory and anti-tumor effects for CP or PDAC, respectively.

Tumor-associated macrophages (TAMs) play a key role in all stages of tumorigenesis and tumor progression. TAMs secrete different kinds of cytokines, chemokines, and enzymes to affect the progression, metastasis, and resistance to therapy depending on their state of reprogramming. Therapeutic benefit in targeting TAMs suggests that macrophages are attractive targets for cancer treatment.

Objective: The study aims to evaluate the effectiveness and safety of Chinese herbal medicine granules Danzhi Qing'e formula (DZQE), Erzhi formula (EZ), and their combination (Combined formula) in the treatment of menopausal symptoms at different stages of menopause.

Methods: Women between the ages of 40 to 60 years, who met menopausal symptoms diagnostic criteria and experienced hot flushes at least 14 times/week in the last 4 weeks, were recruited to participate in a stratified randomized, double-blind, placebo-controlled clinical trial (n = 389). They received a treatment period of 8 weeks and were followed up for 4 weeks.

Background & Aims: Little is known about the pathogenic mechanisms of autoimmune pancreatitis (AIP), an increasingly recognized, immune-mediated form of chronic pancreatitis. Current treatment options are limited and disease relapse is frequent. We investigated factors that contribute to the development of AIP and new therapeutic strategies.

Cyclooxygenase (COX)-2 is increased in human chronic pancreatitis. We recently demonstrated in a model of chronic pancreatitis (WBN/Kob rat) that inhibition of COX-2 activity reduces and delays pancreatic inflammation and fibrosis. Monocyte chemoattractant protein (MCP)-1 mRNA and PGE(2) were significantly reduced, correlating with a decreased infiltration of macrophages.

Background: Regenerating protein (reg) and pancreatic stone protein (PSP) have been discovered independently in the fields of diabetes and pancreatitis.

Materials And Methods: These proteins are identical; however, because of the gap between the endocrine and exocrine field, there was never a consensus and the nomenclature has not been rectified. Since the time of the initial discovery, more isoforms have been unified.

Osteopontin (Opn) is a potent chemoattractant for mononuclear cells that is upregulated in various inflammatory states of the kidney. Opn is believed to contribute to mononuclear cell infiltration and renal injury. The importance of Opn was examined in vivo in rapidly progressive glomerulonephritis in Opn knockout mice.
