Circular RNA ITCH promotes extracellular matrix degradation via activating Wnt/β-catenin signaling in intervertebral disc degeneration.

Intervertebral disc degeneration (IDD) is the prevailing spine disorder and is associated with musculoskeletal disease. The extracellular matrix (ECM) degradation is an essential hallmark of IDD progression. Circular RNAs (circRNAs), as crucial cellular regulators, participate in multiple pathological processes including IDD.

The effectiveness of financial intervention strategies for reducing caesarean section rates: a systematic review.

Background: The increasing trend of Caesarean section (CS) in childbirth has become a global public health challenge. Previous studies have proposed financial intervention strategies for reducing CS rates by limiting caesarean delivery on maternal request (CDMR). This study synthesizes such strategies while evaluating their effectiveness.

[Effect of coicis semen oil on renal interstitial fibrosis in rats with unilateral urethral obstruction].

Objective: To study the effect and mechanism of Coicis Semen oil (Kanglaite injection, KLT) on renal interstitial fibrosis induced by unilateral ureteral obstruction (UUO).

Method: Fifty-four male SD rats were randomly divided into 3 groups, 6 in each group, the sham operated group, the model group, and the KLT group. Renal interstitial fibrosis model was established in rats by UUO.

Acute kidney injury at high altitude.

Acute ascent to high altitudes beyond 2400 m (300 feet) can cause acute mountain sickness (AMS) and may develop into life-threatening complications such as high altitude cerebral (HACE) and pulmonary edema (HAPE). We report a case of acute kidney injury (AKI) without other organ involvement in a previously healthy young man after sudden high altitude exposure of up to 5200 m. Acute systemic hypoxia as well as prolonged renal hypoperfusion may be responsible for his kidney injury.

[Effects of simvastatin on expression of CTGF and α-SMA in renal tubulointerstitium of rats with diabetic nephropathy].

Objective: To investigate the effects of low-dose simvastatin on the expression of connective tissue growth factor (CTGF) and α-smooth muscle actin (α-SMA) in the renal tubulointerstitium of rats with diabetic nephropathy.

Methods: Sixty male SD rats were randomly divided into three groups: Group C (control group), Group D, in which diabetes was induced by stroptozotocin (STZ) and Group DS, in which STZ-induced diabetic rats were treated with low-dose (no cholesterol-lowering effect) simvastatin. The following parameters were measured after 6 weeks and 12 weeks in each groups, respectively: body weight and kidney weight, 24-h urinary albumin excretion (UAE), biochemical indexes including blood glucose (GLU), low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides (TG) and serum creatinine (SCr).

Increased ERCC1 protein expression is associated with suboptimal debulking in advanced epithelial ovarian cancer.

Unlabelled: Some biological features, such as amount of ascites and molecular tissue markers, have been found to correlate with debulking outcome in advanced epithelial ovarian cancer (EOC). This study investigated whether proteins involved in nucleotide excision repair of EOC affected the debulking outcome.

Patients And Methods: The relationship between dichotomised clinical characteristics, ERCC1 and XPD protein expression levels in 78 patients were tested by univariate and multivariate analysis to determine the independent significance of factors for debulking outcome.

Effects of simvastatin on oxidative stress in streptozotocin-induced diabetic rats: a role for glomeruli protection.

Aims: To study the effects of simvastatin on oxidative stress in rats with early stage diabetic nephropathy.

Methods: 60 male Sprague-Dawley rats were divided into three groups: control group (CN), streptozotocin (STZ)-induced diabetic rats group (DM) and STZ-induced diabetic rats group treated with simvastatin (DM+S). The following parameters were measured at weeks 6 and 12 in similar rats chosen randomly from each group: body and kidney weight, 24-hour urinary albumin excretion (UAE), biochemical indexes including blood glucose (GLU), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), serum creatinine (SCr), antioxidant enzymes including superoxide dismutase (SOD), glutathione S-transferase (GST), catalase (CAT) in plasma, lipid peroxidation production as malondialdehyde in plasma (MDAp) and erythrocytes (MDAe), morphology parameters such as glomerular volume (GV) and mesangial area/total glomerular area (M/T).
