Effect of continuous nursing on rehabilitation of older patients with joint replacement after discharge.

Background: Joint replacement is a common treatment for older patients with high incidences of hip joint diseases. However, postoperative recovery is slow and complications are common, which reduces surgical effectiveness. Therefore, patients require long-term, high-quality, and effective nursing interventions to promote rehabilitation.

The Impact of Inflammatory Immune Reactions of the Vascular Niche on Organ Fibrosis.

Inflammation is a type of defense response against tissue damage, and can be mediated by lymphocytes and macrophages. Fibrosis is induced by tissue injury and inflammation, which leads to an increase in fibrous connective tissue in organs and a decrease in organ parenchyma cells, finally leading to organ dysfunction or even failure. The vascular niche is composed of endothelial cells, pericytes, macrophages, and hematopoietic stem cells.

Protective Antioxidant Effects of Amentoflavone and Total Flavonoids from Hedyotis diffusa on H O -Induced HL-O2 Cells through ASK1/p38 MAPK Pathway.

In this study, total flavonoids and total triterpenoid acid were extracted with ethyl acetate from Hedyotis diffusa Willd, and hepatoprotective activities of them and five compounds from total flavonoids against H O induced hepatocyte damage on HL-02 cells were determined. In particular, amentoflavone and total flavonoids had influence on the leakage of ALT, AST, LDH, the activities of SOD and the content of MDA. They effectively reduced the loss of MMP, the release of Cyt C, and then inhibited activation of caspase-3/caspase-9 cascade in hepatotoxic cells.

Epigallocatechin-3-gallate Alleviates Cognitive Deficits in APP/PS1 Mice.

Alzheimer's disease (AD) shows cognitive impairments in clinic, which is multifactorial with different etiopathogenic mechanisms such as Aβ deposition, neuroinflammation and neuronal dystrophy involved.

Epigallocatechin-3-gallate (EGCG) possesses a broad spectrum of pharmacological activities in the prevention and treatment of multiple neurodegenerative diseases.

[Effects of fast-twisting long-retaining acupuncture therapy on apoptosis and expression of related proteins in vestibular nucleus in rats with vertigo induced by posterior circulation ischemia].

Objective: To observe the effects of fast-twisting long-retaining (FTLR) acupuncture therapy on apoptosis of vestibular nucleus and expression of Caspase-3, Bcl-2 and Bax in rats with vertigo induced by posterior circulation ischemia.

Methods: A total of 70 healthy SD rats were randomly divided into a sham operation group, a model group, a medication group, a regular acupuncture group and a FTLR acupuncture group, 14 rats in each group. The rats in the model group, medication group, regular acupuncture group and FTLR acupuncture group were intervented with surgical ligation of the right common carotid artery (CCA) and the right subclavian artery (SCA) to establish the model of vertigo induced by posterior circulation ischemia; in the sham operation group, the right CCA and the right SCA were separated without ligation.

The Role of Connexin-43 in the Inflammatory Process: A New Potential Therapy to Influence Keratitis.

The studies outlined in this review highlight the relationship between inflammatory signaling molecules and connexin-43 (Cx43). Gap junction (GJ) channels and hemichannels (HCs) participate in the metabolic activity between intra- and extracellular space. Some ions and small molecules are exchanged from cell to cell or cell to extracellular space to affect the process of inflammation via GJ.

Role of corneal collagen fibrils in corneal disorders and related pathological conditions.

The cornea is a soft tissue located at the front of the eye with the principal function of transmitting and refracting light rays to precisely sense visual information. Corneal shape, refraction, and stromal stiffness are to a large part determined by corneal fibrils, the arrangements of which define the corneal cells and their functional behaviour. However, the modality and alignment of native corneal collagen lamellae are altered in various corneal pathological states such as infection, injury, keratoconus, corneal scar formation, and keratoprosthesis.
