Objective To analyze the effect of circLRP6 on high glucose-induced renal tubular epithelial cell injury via miR-31-5p/high mobility group protein A1(HMGA1)axis regulation.Methods Human renal tubular epithelial HK-2 cells were cultured in vitro and divided into eight groups:control,high glucose,high glucose+si-NC,high glucose+si-circLRP6,high glucose+si-circLRP6+miR-NC,high glucose+si-circLRP6+miR-31-5p inhibitor,high glucose+si-circLRP6+miR-31-5p inhibitor+si-NC,and high glucose+si-circ-LRP6+ miR-31-5p inhibitor+si-HMGA1.The circLRP6,miR-31-5p,and HMGA1 mRNA levels were determined using real-time quantitative PCR.Cell supernatant IL-6 and tumor necrosis factor-α(TNF-α)levels,lactate dehydrogenase(LDH)activity,and malondialdehyde(MDA)content were also determined.Furthermore,flow cytometry was used to observe cell apoptosis.HMGA1,Bax,and Bcl-2 protein expression was detected by Western blotting.Finally,dual luciferase assay was used to report the targeting relationship of miR-31-5p with circLRP6 and HMGA1.Results Compared with the high glucose group,the HK-2 cell proliferation inhibition rate;cell superserum IL-6,TNF-α,LDH,and MDA levels;apoptosis rate;and Bax protein expression in the high glucose+si-circLRP6 group decreased significantly,whereas Bcl-2 protein expression increased significantly(all P<0.05).Consequently,miR-31-5p downregulation possibly weakened the protective effect of si-circLRP6 on high glucose-induced renal tubular epithelial cell injury.HMGA1 expression inhibition reversed the effect of the si-circLRP6+miR-31-5p inhibitor on high glucose-induced renal tubular epithelial cell injury.Finally,miR-31-5p exhibited a targeting relationship with circLRP6 and HMGA1.Conclusion Si-circLRP6 protects high glucose-induced renal tubular epithelial cell injury via miR-31-5p upregulation and HMGA1 expression inhibition.

OBJECTIVE:
To investigate the role of the SIRT1/NF-κB pathway in mediating the effect of puerarin against lipopolysaccharide (LPS)-induced acute kidney injury (AKI).
METHODS:
Fifteen BALB/C mice were randomized into control group, LPS group and puerarin treatment group, and in the latter two groups, the mice were given an intraperitoneal injection of LPS (5 mg/kg), followed by daily injection of normal saline for 3 days or injection of puerarin (25 mg/kg) given 1 h later and then on a daily basis for 3 days. On day 5 after modeling, the kidney tissues were taken for histological observation and detection of cell apoptosis. The renal function indexes including urea nitrogen (BUN), serum creatinine (Scr) and kidney injury molecule 1 (KIM-1) and the levels of tumor necrosis factor (TNF-α) and interleukin 1β (IL-1β) were measured, and the expressions of SIRT1 and NF-κB-p65(acetyl K310) in the renal tissues were detected.
RESULTS:
Intraperitoneal injection of LPS caused obvious glomerular capillary dilatation, hyperemia, renal interstitial edema, and renal tubular epithelial cell swelling and deformation in the mice. The mouse models of LPS-induced AKI also showed significantly increased renal tubular injury score and renal cell apoptosis (P < 0.01) with increased serum levels of BUN, Scr, KIM-1, TNF-α and IL-1β (P < 0.01), enhanced renal expressions of TNF-α, IL-1β and NF-κB p65(acetyl K310) (P < 0.01) and lowered renal expression of SIRT1 (P < 0.05). Treatment with puerarin effectively alleviated LPS-induced renal interstitial edema and renal tubular epithelial cell shedding, lowered renal tubular injury score (P < 0.01) and renal cell apoptosis rate (P < 0.01), and decreased serum levels of BUN, Scr, KIM, TNF-α and IL-1β (P < 0.01). Puerarin treatment significantly reduced TNF-α, IL-1β and NF-κB p65 (acetyl K310) expression in the renal tissue (P < 0.05) and increased SIRT1 expression by 17% (P < 0.05) in the mouse models.
CONCLUSION
Puerarin can effectively alleviate LPS-induced AKI in mice possibly by modulating the SIRT1/NF-κB signaling pathway.

BACKGROUNDBased on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.
METHODSThe Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.
RESULTSA total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).
CONCLUSIONWe first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.
