Effects of insonification on repairing the renal injury of diabetic nephropathy rats.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionProlonged hyperglycemia in diabetes mellitus can result in the development of diabetic nephropathy (DN) and increase the susceptibility to kidney failure. Low-intensity pulsed ultrasound (LIPUS) is a non-invasive modality that has demonstrated effective tissue repair capabilities. The objective of this study was to showcase the reparative potential of LIPUS on renal injury at both animal and cellular levels, while also determining the optimal pulse length (PL). RESEARCH DESIGN AND
methodsWe established a rat model of DN, and subsequently subjected the rats' kidneys to ultrasound irradiation (PL=0.2 ms, 10 ms, 20 ms). Subsequently, we assessed the structural and functional changes in the kidneys. Additionally, we induced podocyte apoptosis and evaluated its occurrence following ultrasound irradiation.
resultsFollowing irradiation, DN rats exhibited improved mesangial expansion and basement membrane thickening. Uric acid expression increased while urinary microalbumin, podocalyxin in urine, blood urea nitrogen, and serum creatinine levels decreased (p<0.05). These results suggest that the optimal PL was 0.2 ms. Using the optimal PL further demonstrated the reparative effect of LIPUS on DN, it was found that LIPUS could reduce podococyte apoptosis and alleviate kidney injury. Metabolomics revealed differences in metabolites including octanoic acid and seven others and western blot results showed a significant decrease in key enzymes related to lipolysis (p<0.05). Additionally, after irradiating podocytes with different PLs, we observed suppressed apoptosis (p<0.05), confirming the optimal PL as 0.2 ms.
conclusionsLIPUS has been demonstrated to effectively restore renal structure and function in DN rats, with an optimal PL of 0.2 ms. The mechanism underlying the alleviation of DN by LIPUS is attributed to its ability to improve lipid metabolism disorder. These findings suggest that LIPUS may provide a novel perspective for future research in this field.
