AIM: To explore the effects of fluctuant high blood glucose and stable high blood glucose on apoptosis and the expression of Bax and Bcl-2 in glomerular endothelial cells and renal tubular epithelial cells in diabetic rats. METHODS: 24 SD rats were divided into 3 groups: control group, stable high blood glucose group and fluctuant high blood glucose group. Diabetic rats were induced by intraperitoneal injection of STZ, and the fluctuant high blood glucose animal model was induced by intraperitoneal injection of aspart and glucose at different time points every day. Apoptosis was assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL), and immunohistochemistry was used to detect apoptosis associated gene bax and bcl-2 expression in kidney. RESULTS: After 4 experimental weeks, a significant increase in cell apoptosis, up-regulation of Bax protein expression in kidney tubular epithelial cell and down-regulation of Bcl-2 in glomerular endothelial cell in fluctuant high blood glucose rats were observed compared with stable high blood glucose rats.CONCLUSION: Fluctuant high blood glucose induces more apoptosis in renal tubular epithelial cells than that in stable high blood glucose diabetic rats.

Objective To explore the effects of oscillating blood glucose on apoptosis in renal tubular epithelial cells of diabetic rats and the role of oxidative stress.Methods Renal tubular epithelial cells (HK-2) were cultured in vitro with stable high glucose or oscillating high glucose,and MTF assay was applied to the neasurement of cell proliferation.Streptozotocin induced diabetic model was established with SD rats and the oscillating high blood glucose animal model was induced by intraperitoneal injection of insulin and glucose at different time points every.day.12 weeks later 24 h urine protein (24hUP),blood urea nitrogen (BUN),serum creatinine (Scr),superoxide dismutase (SOD), and malondialdehyde (MDA)were determined. Apoptosis was assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL),and immunohisto-chemistry was used to detect apoptosis associated gene Bax,Bcl-2,and NOX-4 expression in kidney.Changes in ultrastructure were observed.Results Oscillating high glucose may inhibit renal cells proliferation obviously when comparing with stable high glucose.In the rats with oscillating blood glucose rather than those with stable high blood glucose,there was a significant increase of BUN,Scr,24hUP,and MDA and a decrease of SOD[ (21.50 ± 1.72 vs 12.50 ± 1.85 )mmol/L,(97.51 ± 7.84 vs 82.12 ± 11.48 ) μmol/L,( 1.57 ± 0.09 vs 1.04 ± 0.12 ) mg/24 h,( 23.50 ± 1.87 vs 14.82 ± 2.96) nmol/ml,( 17.22 ± 1.12 vs 21.11 ± 1.80) U/ml,all P<0.05 ] ; cell apoptosis was intensified with the up-regulation of Bax and NOX-4 protein expression and down-regulation of Bcl-2 in glomerular endothelial cells; and more severe pathological damages were observed.ConclusionComparing with stable high blood glucose,oscillating high blood glucose induces more apoptosis and less proliferation of renal tubular epithelial cells and the mechanism may be related to the increased oxidative stress.

The aim of this study was to evaluate the roles of interleukin (IL)-17A in risk stratification and prognosis of patients with sepsis-associated acute kidney injury (SAKI). Methods: We enrolled 146 sepsis patients (84 non-SAKI and 62 SAKI patients) admitted to the emergency department from November 2020 to November 2021. Patients with SAKI were differentiated based on the severity of acute kidney injury. All clinical parameters were evaluated upon admission before administering antibiotic treatment. Inflammatory cytokines were assessed using flow cytometry and the Pylon 3D automated immunoassay system (ET Healthcare). In addition, a receiver operating characteristic (ROC) curve was utilized to determine the prognostic values of IL-17A in SAKI. Results: The levels of creatinine, IL-2, IL-4, IL-6, IL-17A, tumor necrosis factor alpha, C-reactive protein, and procalcitonin (PCT) were significantly higher in the SAKI group than in the non-SAKI group (p < 0.05). The level of IL-17A revealed significant differences among stages 1, 2, and 3 in SAKI patients (p < 0.05). The mean levels of PCT, IL-4, and IL-17A were significantly higher in the non-survival group than in the survival group in SAKI patients (p < 0.05). In addition, the area under the ROC curve of IL-17A was 0.811. Moreover, the IL-17A cutoff for differentiating survivors from non-survivors was 4.7 pg/mL, of which the sensitivity and specificity were 77.4% and 71.0%, respectively. Conclusion: Elevated levels of IL-17A could predict that SAKI patients are significantly prone to worsening kidney injury with higher mortality. The usefulness of IL-17A in treating SAKI requires further research.

OBJECTIVES:
High fat-induced podocyte injury is one of the important factors leading to obesity related nephropathy (ORG), but the mechanism is not clear. This study aims to explore the mechanism of period circadian clock 3 (PER3) in the oxidative stress and inflammation induced by palmitic acid (PA) in podocytes.
METHODS:
The C57BL/6J mice were fed with chow and high-fat diet for 16 weeks. The PER3 expression in kidney tissues were detected in the normal body weight group and the obesity group. The PER3 mRNA and protein expression were detected after the podocytes were induced with different concentrations (0, 50, 150 and 300 μmol/L) of PA for 48 h. The PER3 mRNA and protein expression were detected after the podocytes were induced with 150 μmol/L PA for 0, 24, 36, and 48 h. Triglyceride (TG) levels were examined in the PA group, the adenovirus (ad)-PER3+PA group, and the siRNA-PER+PA group after the podocytes were transfected by Ad-PER3 or small interfering RNA (siRNA)-PER3 for 48 h and subsequently were induced with 150 μmol/L PA for 48 h. The differential gene expression was detected using RNA sequencing (RNA-seq) after podocytes were transfected by siRNA-PER3 (siRNA-PER3 group) and siRNA-control (siRNA-control group), respectively. The mRNA levels of nephrin, podocin, podocalyxin, podoplanin, superoxide dismutase 1 (SOD1), glutathione peroxidase 1 (GPX1), catalase (CAT), and the levels of malondialdehyde (MDA), glutathione (GSH), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β) and interleukin-2 (IL-2) were detected after podocytes were transfected with Ad-PER3 or Ad-control for 48 h and then they were induced by 150 μmol/L PA for 48 h.
RESULTS:
The PER3 was down-regulated in the obesity group compared with the normal body weight group (
CONCLUSIONS
PER3 can decrease the PA-induced oxidative stress and inflammatory factor secretion via inhibiting the lipogenesis in podocytes.

Objective:To investigate the clinical effect of lateral rectus abdominis approach combined with presacral decompression for surgical treatment of old Denis type II sacral fractures complicated with upper sacral plexus injury.Methods:A retrospective case series study was performed on the clinical data of 9 patients with old Denis type II sacral fractures complicated with upper sacral plexus injury (L 4-S 1) admitted to Zhongnan Hospital of Wuhan University from June 2010 to December 2016. There were 6 males and 3 females, aged (33.1±7.5)years (range, 15-58 years). Embolization of internal iliac artery and preimplantation of abdominal aortic balloon were performed 2 hours before operation under the guidance of digital subtraction angiography (DSA). Surgery was performed using a single lateral rectus abdominis approach combined with presacral decompression. The operation time, intraoperative blood loss and full weight-bearing time were recorded. The visual analogue scale (VAS) and European QOL Five Dimensional health scale (EQ-5D) were compared before and after operation. The Gibbons' impairment scale was used to assess neurological function. X-ray and CT scan were used to observe internal fixation and fracture healing. The complications during and after operation were recorded. Results:The patients were followed up for 24-52 months [(35.2±5.2)months]. The operation time was (2.9±0.6)hours. The intraoperative bleeding was (573±138)ml, and the full weight-bearing time was (11.6±1.2)weeks. X-ray and CT scan showed bone healing in all patients at the latest follow-up. The VAS and EQ-5D scale improved from preoperative (7.8±0.6)points and (0.34±0.07)points to the final follow-up of (0.8±0.3)points and (0.81±0.05)points ( P<0.05). According to Gibbons classification, 8 patients were grade I and 1 patient was grade II one year after operation ( P<0.01). Namely, the radiation pain of lower extremities was significantly improved in all patients, among which 8 patients showed pain disappeared and completely returned to normal and 1 patient showed residual numbness and hypoesthesia of the affected limbs. No major complications (eg, iatrogenic lumbosacral plexus injury, vital blood vessels or pelvic organs injury) occurred during the operation. During the follow-up period, only one patient developed traumatic hip arthritis and underwent total hip arthroplasty 6 months after operation. Fractures of the remaining patients were healed well without complications like infection, pressure ulcer or implant failure. Conclusions:For old Denis type II sacral fractures complicated with upper sacral plexus injury, lateral rectus abdominis approach combined with presacral decompression can fully decompress the upper sacral plexus nerve, relieve pain, and promote functional rehabilitation, with low incidence of complications. It is an alternative surgical method for the treatment of old Denis type II sacral fractures complicated with upper sacral plexus injury.
