BackgroundMany plant original foods have been shown beneficial effects in humans. In the previous work, we have developed a compound capsule which contains major constituents of walnut oil and grape seed extract.ObjectiveTo investigate the antioxidant effects of the Compound Walnut Oil Capsule (WOC) in aging model induced by D-gal.Design70 C57BL/6J mice were randomly divided into seven groups. Mice in normal group received daily subcutaneous injection of saline while the control group, WOC groups, Vitamin C (VC) group and pure walnut oil group received daily subcutaneous injection of D-galactose (D-gal) for 8 weeks. Total antioxidant capacity (T-AOC), super dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) in serum, liver and brain were determined. The expression of Heme Oxygenase (HO-1), iNOS and Klotho in liver and brain were obtained.ResultsWOC could improve the pathologic lesions caused by oxidative stress and significantly enhance the T-AOC, increase the activities of SOD, GSH-Px and decrease the contents of MDA in serum, liver and brain. Also, the WOC could obviously up-regulate the expression of HO-1 and Klotho and down-regulate the expression of iNOS.ConclusionWOC can be used as an anti-aging food for its effectively eliminating free radicals, enhancing the antioxidant capacity and alleviating the damages of oxidative stress.
In order to explore the factors of patients with type 2 diabetic nephropathy (DN), in this paper, 257 patients with type 2 diabetic nephropathy in Zhejiang province were observed, with 156 males and 101 females. The age range was 53–69 years old. According to the ratio of urine albumin/creatinine, it was divided into two groups: the diabetic nephropathy group and the nondiabetic nephropathy group. Age, diabetic course, hypertension, body mass index, glycated hemoglobin, total gallbladder alcohol, high-density lipoprotein, and low-density lipoprotein were compared. The results showed that diabetic diseases, hypertension, HBA1C, and LDL-C were independent risk factors for diabetic nephropathy, and HDL-C was the independent protection factor of DKD (

). Therefore, malnutrition and microinflammatory state are the risk causes of the quality of life and survival rate of type 2 diabetic nephropathy MHD patients and actively improve nutritional status. Reducing the status of microinflammatory disease is especially important.
Multidrug resistance (MDR) is a major cause of cancer chemotherapy failure, and it is important to develop suitable reversal agents to overcome MDR. A majority of chemical reversal agents have acceptable reversal effects. However, the toxicity and adverse reactions associated with these agents restricts their clinical use. Chinese medicines (CMs) have lower toxicities and adverse reactions and are associated with multiple components, multiple targets and reduced toxicity. CMs have several advantages and could reverse MDR, decrease drug dosage, enhance patient compliance and increase efficacy. This review summarizes the current progress of CM reversal agents..
Nicotine is a major carcinogen in cigarettes, which can enhance cell proliferation and metastasis and increase the chemoresistance of cancer cells. Our previous data found that nicotine promotes cell survival in lung cancer by affecting the expression of antiapoptotic protein Mcl‐1, suggesting that the Mcl‐1 may be a therapeutic target for patients with lung cancer. In this study, we found that the effects of drug resistance on nicotine‐induced lung cancer cell lines were shown to influence the phosphorylation of Mcl‐1. Moreover, nicotine induces Mcl‐1 phosphorylation exclusively at the T163 site, which results in enhancement of the antiapoptotic activity of Mcl‐1 and increased cell survival. Meanwhile, nicotine can reduce the sensitivity of H1299 cells to CDDP via enhancement of the binding of Mcl‐1 to Bak, which inhibits the proapoptotic effect of Bak and ultimately leads to increased survival and drug resistance of lung cancer cells. Thus, nicotine‐induced cell survival and chemoresistance may occur in a mechanism by stimulating Mcl‐1 phosphorylation and its interaction with Bak, which may contribute to improving the efficacy of chemotherapy in the treatment of human lung cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
