In traditional Chinese medicine, the flower of Pueraria lobata (Puerariae Flos) has been used in therapy to counteract the problems associated with alcohol drinking and liver injury. In this study, we investigated the hepatoprotective effects and its mechanisms of tectoridin, an isoflavone glycoside from the flower of P. lobata (Willd.) Ohwi. Ethanol(More)
Large-conductance Ca(2+)-activated K(+) (BK) channels can regulate cellular excitability in complex ways because they are able to respond independently to two distinct cellular signals, cytosolic Ca(2+) and membrane potential. In rat chromaffin cells (RCC), inactivating BK(i) and noninactivating (BK(s)) channels differentially contribute to RCC action(More)
The structural basis underlying the gating of large conductance Ca(2+)-activated K(+) (BK) channels remains elusive. We found that substitution of Leu-312 in the S6 transmembrane segment of mSlo1 BK channels with hydrophilic amino acids of smaller side-chain volume favored the open state. The sensitivities of channels to calcium and voltage were modified by(More)
Ginsenoside Rb1 (Rb1), a natural compound extracted from ginseng, exerts anti-obesity activity and improves insulin sensitivity in high-fat diet (HFD)-induced obese rats. The objective of the current study was to evaluate the protective effect of Rb1 on fatty liver in HFD-induced obese rats and to elucidate underlying mechanisms. After chronic(More)
OBJECTIVE To investigate the efficacy of transcutaneous electrical nerve stimulation (TENS) on four specific acupuncture points Hegu (LI4), Neiguan (PC6), Danshu (BL19) and Weishu (BL21) for reducing pain in labor. METHODS A total of 160 voluntary nulliparous women who were willing to receive TENS for analgesia were assigned to the treatment group after(More)
OBJECTIVE To investigate the association of Sp110 gene SNP with tuberculosis occurrence of Chongqing Han people. METHODS Design Use the case-control study design, and collect risk factors of tuberculosis by questionnaires. Use multiple methods to detect rs1135791C/T, rs722555A/G, 5'-UTR rs11679983A/G, rs28930679C/T, rs9061A/G, rs1063154G/T, rs1047254A/G,(More)
Retinal neovascularization (NV) occurs in various ocular disorders including proliferative diabetic retinopathy, retinopathy of prematurity and secondary neovascular glaucoma, which often result in blindness. Vascular endothelial growth factor (VEGF) is an essential growth factor for angiogenesis, and is particularly regulated by hypoxia inducible(More)
PURPOSE To evaluate the clinical effectiveness of two different one-step self-etching adhesives. METHODS Two single-step self-etching adhesive systems, Clearfil Tri-S Bond and G-Bond, were evaluated. As a control, a two-step self-etching adhesive system, Clearfil SE Bond, was used. The teeth to be restored were randomly assigned. The resin composite used(More)
PURPOSE To evaluate the clinical value of the contrast agent SonoVue in the treatment of uterine fibroids with ultrasound-guided high intensity focused ultrasound (HIFU) therapeutic ablation. MATERIALS AND METHODS A total of 291 patients with solitary uterine fibroid from three centers were treated with ultrasound-guided HIFU. Among them, 129 patients(More)
Recently, population-based studies of type 2 diabetes patients have provided evidence that metformin treatment is associated with a reduced cancer incidence and mortality, but its mode of action remains unclear. Here we report effects of metformin on hepatocellular carcinoma (HCC) Hep-G2 cells and details of molecular mechanisms of metformin activity. Our(More)
