OBJECTIVE To investigate insulin secretion function and insulin resistance in Chinese newly diagnosed type 2 diabetes (obese and non-obese patients) in order to provide evidence for clinical treatment. METHODS 408 newly diagnosed type 2 diabetes and 40 normal controls were recruited. Height, weight were measured, insulin and glucose of 0 min, 30 min, 60(More)
Sunspot number time series, as a multivariable, strong coupling and nonlinear time series, has encountered troubles to describe its changes rules with modeling method owing to great complexity of sunspot number change. The main aim of this study is to develop a novel prediction method, based on the Quantum Neural Networks, which is composed of some quantum(More)
Manipulation of surface plasmon polaritons (SPPs) on metal surfaces is important for constructing ultracompact integrated micro/nano optical devices and systems. We employ the method of surface electromagnetic wave holography (SWH) to design holographic groove patterns for managing the transport of broadband SPPs on metal surface. Several sets of groove(More)
Phytochemical reinvestigation of the dried roots and rhizomes of Helleborus thibetanus afforded four new minor spirostanol glycosides (1-4) and four known spirostanol glycosides (5-8). Their structures were determined on the basis of spectroscopic analyses, including 1D and 2D NMR experiments, together with HR-ESI-MS and IR measurements and the results of(More)
BACKGROUND A report published by the World Health Organization indicates that depression typically first manifests during youth. However, adolescents usually lack the capacity for self-help or to seek help proactively from health professionals or other related resources to relieve their emotional distress. Failing to manage depression appropriately places(More)
Three new steroidal saponins including two spirostanol glycosides (1-2) and one furostanol glycoside 1-sulphate (3) were isolated from the dried roots and rhizomes of Helleborus thibetanus. Structures of the compounds were determined on the basis of extensive use of 1-D and 2-D NMR experiments, together with HR-ESI-MS and IR measurements, as well as the(More)
AimTissue engineering is a promising area with a broad range of applications in the fields of regenerative medicine and human health. The emergence of periodontal tissue engineering for clinical treatment of periodontal disease has opened a new therapeutic avenue. The choice of scaffold is crucial. This study was conducted to prepare zein scaffold and(More)
OBJECTIVE To evaluate the effects of sibutramine on body weight, body fat mass, metabolism of plasma glucose and serum lipids, and insulin resistance (IR) in primary obesity patients. METHODS A double-blind, double-placebo, randomized controlled, multi-center clinical trial was conducted. 359 voluntary obese subjects, whose body mass index (BMI) > or = 27(More)
AIM To investigate the levels of selenium (Se) and several cytokines (TNF-alpha, VEGF and IL-1beta) in the serum of patients with Kaschin-Beck disease (KBD). METHODS 90 subjects were selected, from KBD areas and non-KBD areas of Lhasa, Tibet. Then they were divided into 3 groups: the group with KBD (30), the control in KBD areas (30), and the control in(More)
AimTo investigate the role of the Chinese herbal medicine Xianhuayin on the reversal of 7,12‐dimethylbenz[a]anthracene (DMBA)‐induced premalignant mucosal lesions in the oral buccal pouch of golden hamsters.MethodologyThe animals were randomly divided into a non‐diseased control group (n=5) and an experimental group including 50 animals in which the buccal(More)
