Chemistry-led investigations into the mode of action of NAMPT activators, resulting in the discovery of non-pyridyl class NAMPT activators

The cofactor nicotinamide adenine dinucleotide (NAD+) plays a key role in a wide range of physiological processes and maintaining or enhancing NAD+ levels is an established approach to enhancing healthy aging. Recently, several classes of nicotinamide phosphoribosyl transferase (NAMPT) activators have been shown to increase NAD+ levels in vitro and in vivo and to demonstrate beneficial effects in animal models. The best validated of these compounds are structurally related to known urea-type NAMPT inhibitors, however the basis for the switch from inhibitory activity to activation is not well understood. Here we report an evaluation of the structure activity relationships of NAMPT activators by designing, synthesising and testing compounds from other NAMPT ligand chemotypes and mimetics of putative phosphoribosylated adducts of known activators. The results of these studies led us to hypothesise that these activators act via a through-water interaction in the NAMPT active site, resulting in the design of the first known urea-class NAMPT activator that does not utilise a pyridine-like warhead, which shows similar or greater activity as a NAMPT activator in biochemical and cellular assays relative to known analogues.

Research progress in coping style assessment tools for elderly patients with urinary incontinence / 中南大学学报(医学版)

Coping style is a cognitive or behavioral strategy taken by individuals in the face of stress. Positive coping style is of great significance for improving the physical and mental outcomes of elderly patients with urinary incontinence. Accurate assessment of coping styles for the elderly patients with urinary incontinence can provide reference for the subsequent development of intervention measures. The existing coping style assessment tools for elderly incontinence at home and abroad include specific scale of incontinence, relevant psychological assessment scale, and universal scale. In a word, the progress in the studies on relevant assessment tools is slow, and it mainly focuses on the assessment of female population. The assessment content is relatively single and lacks of pertinence and systematization. In the future, a comprehensive scale with strong adaptability should be developed based on the characteristics of elderly incontinence patients in China.

Icaritin prevents vascular calcification in mice / 中南大学学报(医学版)

To explore the effect of icaritin on preventing the vascular calcification in mouse induced by vitamin D2.
 Methods: Fifty male C57BL mice were randomly assigned to a control group (n=10) and a model group (n=40). Mice in model group were treated with gradient-concentration of icaritin for 8 weeks. Then, they were consecutively treated with vitamin D2 for 4 days. Meanwhile, mice in negative control group were treated with the same dosage of PBS. At the end of the treatment, aortae were collected to examine the concentration of Ca, the area of calcification and the expression of α-smooth muscle actin (α-SMA) and Runx2.
 Results: Compared with the negative control group, the weight of mice and the concentration of Ca in the positive control (vitamin D2+0 mg/kg icaritin) group declined significantly (P<0.05) after injection of vitamin D2. Compared with the positive control group, the Ca concentration, the area of calcification, and the expression of Runx2 were significantly declined at the middle dosage of icaritin (vitamin D2+0.2 mg/kg icaritin) group (P<0.05).
 Conclusion: Icaritin could effectively prevent the vascular calcification in mice.

Objective:To investigate the criterion-related validity of Menopause-Specific Quality of Life Questionnaire (MENQOL)-Chinese version and to evaluate the effect of menopausal symptoms on health related quality of life. Methods:This study was a cross-sectional survey. Three communities were randomly chosenin Changsha,and then 340 menopausal women aged 45-55 years were randomly chosen from the documented data of the 3 community health service centers. They were required to fill out 4 questionnaires: demographic questionnaire, MENQOL-Chinese version, Kupperman Index (KI) and World Health Organization Quality of Life (WHQOL)-BREF. Correlation analysis was used to measure the criterion-related validity. Results: MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) and KI total score were positively correlated (r=0.800,0.751, 0.607, 0.906 respectively); while negatively correlated with WHOQOL-BREF total score (r =-0.694,-0.851,-0.585,-0.873 respectively); MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) were signiifcantly correlated with WHOQOL-BREF subscales (physical, psychological, social relationship, environment), and the physical domain was the highest among the correlation coeffcients (r=-0.915). Conclusion:MENQOL-Chinese version shows relatively high criterion-related validity compared with KI and WHOQOL-BREF, which can be widely used to measure the quality of life of menopause women in China.

Serum omentin-1 concentration and bone mineral density in postmenopausal women / 中南大学学报(医学版)

Objective: To determine the relationship between serum omentin-1 concentration and bone mineral desity in postmenopausal women, and the adipose influence of tissue on bone mineral density (BMD). Methods: BMD values of 336 participants were measured by dual-energy-x-ray absorptiometry (DEXA) at various skeletal sites: the anteroposterior spine, femeral neck, total hip (T-hip) and total body BMD (TBMD). Body compositions including lean tissue mass (LTM) and body fat mass (FBM) were measured by DEXA. hTe plasma concentrations of adipocytokines (omentin-1, adiponectin,leptin,resistin,visfatin, andapelin) were measured by ELISA. Results: hTe overweight and obese groups had higher T-hip,femerol neck, intertrochanter BMDthan the nomal weight group. Plasma omentin-1 was negatively correlated with anteroposterior spine, femeral neck, trochanter, intertrochanter, T-hip and Ward’s BMD, after adjustment for age, BMI and fat body mass, and the correlation was not significant. Multiple stepwise regression anlysis revealed that lean body mass, menopause duration and estrogen level were the most important variables affecting the BMD and each explained 12.2%–13.7%, 6.9%–13.1%, 0.9%–1.7% of the variance. Serum adiponectin was independently associated with T-hip, lumbar spine and total BMD. Conclusion: Plasma omentin-1 is not significantly correlated with BMD in postmenopausal women. Lean body mass, menopause duration and estrogen level are the most important variables affecting the BMD. Serum adiponectin is an independent predictor of T-hip, lumbar spine and total BMD.
