Randomized Controlled Trial
Transcutaneous Electrical Acupoint Stimulation for Improving Postoperative Recovery, Reducing Stress and Inflammatory Responses in Elderly Patient Undergoing Knee Surgery.
Transcutaneous electrical acupoint stimulation (TEAS) is a form of acupuncture treatment that applies electrical stimulation on specific acupoint through cutaneous electrodes. This technique has been used for perioperative anesthesia management as part of after surgery recovery. However, to date, limited data are available for using the TEAS for postoperative recovery in elderly surgical patients. ⋯ Our data showed that the QoR-40 was significantly lower in Group C than that in Group E at postoperative day 1 (p<0.05); Similarly, Cortisol (COR), Adrenocorticotropic Hormone (ACTH), and C-reactive protein (CRP) were significantly lower in Group E than those of Group C at postoperative day 1, 3, and 7 (p<0.05), while the neutrophil/lymphocyte ratio (N/L) was lower in Group E than that in Group C at postoperative day 1 and 3 (p<0.05). Our results showed that perioperative TEAS administration is able to facilitate the development of postoperative recovery of elderly patients, especially at the early stage after surgery. The reported results are likely to be mediated by the reduction of surgical inflammation and perioperative stress response.

Fisetin, a naturally occurring flavonoid, is found in common fruits and vegetables and has been shown to induce cytotoxic effects in many human cancer cell lines. No information has shown that fisetin induced cell cycle arrest and apoptosis in mouse leukemia WEHI-3 cells. We found that fisetin decreased total viable cells through G0/G1 phase arrest and induced sub-G1 phase (apoptosis). ⋯ Furthermore, fisetin increased the protein expression of cytochrome c and AIF. Fisetin decreased cell number through G0/G1 phase arrest via the inhibition of cdc25c and induction of apoptosis through caspase-dependent and mitochondria-dependent pathways. Therefore, fisetin may be useful as a potential therapeutic agent for leukemia.

Canavalia gladiata, known as sword bean, has been used as a Chinese traditional medicine for anti-inflammatory effects. However, the action mechanisms of sword bean have not yet been clearly defined. In the present study, the whole parts of a ripened sword bean (RSB) and the green sword bean (GSB) containing bean pod were extracted with ethanol by reflux extraction. ⋯ Western blotting and immunostaining analysis showed that RSBE and GSBE inhibited the nuclear translocation of NF-κB subunits, which correlated with the inhibitory effects on inhibitor kappa B (IκB) degradation. In dextran sulfated sodium (DSS)-induced colitis mice model, RSBE restored body weight, colon length, and the levels of pro-inflammatory cytokines, such as TNF-α, IL-6, interleukin-1β (IL-1β), and interferon-γ (IFN-γ). In addition, RSBE significantly suppressed the expression of COX-2, iNOS, and NF-κB.

Lycium barbarum polysaccharides (LBP) are the major ingredients of wolfberry. In this study, we investigated the role of LBP in endothelial dysfunction induced by oxidative stress and the underlying mechanisms using thoracic aortic endothelial cells of rat (RAECs) as a model. ⋯ In addition, Ang II treatment increased the expression of EGFR and p-EGFR (Try1172) and which can be inhibited by LBP. On the contrary, expression of ErbB2, p-ErbB2 (Try1248), PI3K, p-e-NOS (Ser1177) ( P < 0 . 0 5 ), and p-AKT (Ser473) ( P < 0 . 0 5 ) was inhibited by Ang II treatment and which can be increased by LBP. Treatment of the cells with inhibitors showed that the regulation of p-e-NOS and p-AKT expression by Ang II and LBP can be blocked by PI3K inhibitor wortmannin but not EGFR and ErbB2 inhibitor AC480. Taken together, our results suggested that LBP plays a critical role in maintaining the integrality of blood vessel endothelium through reduced production of ROS via regulating the activity of EGFR, ErbB2, PI3K/AKT/e-NOS, and which may offer a novel therapeutic option in the management of endothelial dysfunction.

Asthma is a common allergic airway inflammatory disease, characterized by abnormal breathing due to bronchial inflammation. Asthma aggravates the patient's quality of life and needs continuous pharmacological treatment. Therefore, discovery of drugs for the treatment of asthma is an important area of human health. ⋯ In RBL-2H3 cells, CAE down-regulated release of β -hexosaminidase and histamine by reducing the intracellular calcium influx. In addition, CAE suppressed the expression of proinflammatory cytokines by inhibiting nuclear translocation of nuclear factor- κ B. Taken together, our findings suggest that CAE may help in the prevention or treatment of airway inflammatory diseases.
