05). Blebbistatin manufacturer Cox proportion regression model analysis showed that TSP1 was a risk factor affecting the occurrence of MACE in ACS patients; Kaplan-Meier survival analysis showed that the patients with high levels of TSP1 had a higher incidence of longterm MACE than those with low TSP1 levels.

A lowered serum ADAMTS13 level and an elevated TSP1 level can support the diagnosis of ACS. An elevated TSP1 level may serve as an indicator for predicting the risk of MACE in patients with ACS.

To explore the role of endoplasmic reticulum stress in heat stress-induced apoptosis of human neuroblastoma SH-SY5Y cells.

SH-SY5Y cells were incubated at 43 ℃ for 2 h followed by further culture at 37 ℃ for 0, 3 h, or 6 h. With the cells cultured at 37 ℃ as the control, the cells exposed to heat stress were examined for morphological changes under optical microscope and changes in cell viability using CCK-8 assay. Flow cytometry was performed for detecting apoptosis of the cells following heat stress, and intracellular Ca
level in the cells was determined using flow cytometry and immunofluorescence confocal microscopy. The mRNA expression levels of caspase-12, BIP and XBP-1 in the cells were detected using qRT-PCR, and the protein expressions of caspase-12, BIP, P-JNK, JNK and XBP-1 were examined using Western blotting. The effect of pretreatment with 4-PBA on cell apoptosis following heat stress was analyzed with Western blotting.

SH-SY5Y cells showed obvious cell shrinkage immediately after the expgering endoplasmic reticulum stress and the imbalance of intracellular calcium ion homeostasis.
To investigate the effect of orexin-A on the functionality of ionotropic γ-aminobutyric acid (GABA) receptors in spinal cord ventral horn neurons and its mechanisms.

The spinal cord containing the lumbosacral enlargement was isolated from neonatal SD rats (7-12 days old) and sliced. The slices were digested with papain (in 0.18 g/30 mL artificial cerebrospinal fluid) for 40-60 min, and the ventral horn neurons were separated acutely using fire-polished Pasteur pipettes. After the cells adhered to the bottom of Petri dishes, patch-clamp experiments combined with pharmacological methods were performed to test the effects of orexin-A on GABA currents of the neurons treated with SB334867 (a selective OX
R antagonist), TCSOX229 (a selective OX
R antagonist), Bis-Ⅳ (a PKC inhibitor), PMA (a PKC agonist), Rp-cAMP (a PKA inhibitor), or BAPTA (Ca
chelator).

The isolated neurons maintained good morphologies with diverse shapes of cell body and long protrusions. Treatment with orexin-A significantly inhibited ts GABA currents in the ventral horn neurons of rat spinal cord probably by activating OX
R, OX
R and Ca
-independent PKC.

To assess the effects of curcumol on the proliferation, apoptosis and collagen synthesis of keloid fibroblasts and explore the underlying mechanism.

Keloid fibroblasts were treated with different concentrations of curcumol (10, 20, 40, 80 and 160 mg/L) or with 160 mg/L curcumol and 20 μmol/L ISO (an ERK signaling pathway activator). Western blotting was performed to detect the expression levels of proliferation-associated proteins (cyclin D1 and PCNA), fibrosis marker proteins (Col1A1, Col3A1 and
-SMA), apoptosis proteins (Bcl-2, Bax and cleaved caspase-3) and ERK signaling pathway proteins (p-ERK1/2, p-MEK and p-c-Raf) in the cells. MTT assay and flow cytometry were used to evaluate the proliferation and apoptosis rate of the treated cells, respectively.

Curcumol at 10, 20, 40, 80 and 160 mg/L all reduced the protein expressions of cyclin D1, PCNA and Bcl-2, inhibited the expressions of fibrotic marker proteins Col1A1, Col3A1 and α-SMA, decreased the levels of ERK signaling pathway proteins p-ERK1/2, p-MEK and p-c-Raf, and increased the expressions of Bax and cleaved caspase-3 proteins (
< 0.05). Curcumol treatment at 160 mg/L obviously inhibited the proliferation and collagen synthesis, promoted cell apoptosis and inhibited the ERK signaling pathway in the keloid fibroblasts; treatment with ISO significantly reversed the effects of curcumol on the proliferation, apoptosis, collagen synthesis and ERK signal pathway of the cells.

To investigate the antioxidant effect of DJ-1 (Park7) in rats with cerebral ischemia/reperfusion (IR) injury and its potential mechanism.

A total of 108 SD rats were randomly divided into sham-operated group, middle cerebral artery occlusion (MCAO) group, Scramble group, DJ-1 siRNA group, negative control (NC) group and DJ-1 overexpression group. Except for those in the sham group, all the rats were subjected to MCAO to establish models of cerebral IR injury. In DJ-1 siRNA and DJ-1 overexpression group, a DJ-1 siRNA and an adeno-associated virus vector carrying DJ-1 gene was injected into the lateral ventricle of the rats, respectively. In each group, neurological scores and brain water content were determined after the operation, and pathological changes of the brain tissue and neuronal injury in the cortical infarction area were assessed using HE and Nissl staining. Oxidative stress in the brain tissues was analyzed by detecting superoxide dismutase (SOD) and malondialdehyde (MDA). The expression levelstive factor, DJ-1 alleviates oxidative stress induced by cerebral IR injury in rats by activating the Nrf2 pathway.
To investigate the protective effects of betelnut polyphenols on the vital organs against high-altitude hypoxia in rats.

We compared low-, medium-, and high- dose betelnut polyphenols (400, 800, and 1600 mg/kg, respectively) and rhodiola the effects of against high-altitude hypoxia in Wistar rats. The rats were kept in normal condition and given the drugs daily for 3 days before transfer to a facility at the altitude of 4010 m, where the rats were kept for 5 consecutive days for hypoxic exposure. The rats were then euthanized for measuring arterial blood gas and assessing liver, lung, brain and cardiac pathologies with HE staining. SOD activity, MDA content and GSH content in the organs were measured, and serum levels of inflammatory factors were detected using a protein microarray.

Acute exposure to hypoxia significantly reduced blood oxygen saturation of the rats (
< 0.05), caused damages in the liver, lung, brain and myocardium, lowered SOD activity and GSH content and increased MDA content in the vital organs, and increased serum levels of TIMP-1, MCP-1, ICAM-1, and L-selectin (
< 0.
