1.Relation between B7-1 and pathogenesis of proteinuria
International Journal of Pediatrics 2015;42(6):629-631
For children suffering from primary nephrotic syndrome(PNS), podocyte is a crucial part of glomerular filtration barrier, whose injury usually causes proteinuria.The structural and functional integrity of podocyte cytoskeleton is the prerequisite of its normal physiological function.Recent studies demonstrated that under a certain pathological condition, B7-1, expressed in podocyte, can inhibit the activation of β1 integrin by competitively binding to the target site on the β1 integration, which may change the morphology and function of podocyte, consequently induced proteinuria.Other studies also have showed that abatacept, which selectively inhibit the cross-talk between B7-1 and β1-integrin,can reduce proteinuria in patients with B7-1-positive glomerular disease.These studies suggested that B7-1 may be a potential diagnostic biomarker and therapeutic target in proteinuria in PNS.This review summarizes the role of B7-1 expressed in podocyte in the pathogenesis of proteinuria and the possibility of clinical application in the future.

Objective:To investigate the curative effect of Chinese medicine foot bath combined with foot massage on diabetic peripheral neuropathy (DPN).Methods:Seventy-six patients with DPN who received treatment in Lishui Hospital of Traditional Chinese Medicine from July 2018 to December 2019 were included in this study. They were randomly assigned to undergo either Chinese medicine foot bath combined with foot massage (combined treatment group, n = 38) or Chinese medicine foot bath alone (single treatment group, n = 38) for 4 successive weeks in addition to diet and exercise management, medication for lowing blood glucose level, microcirculation improvement, and neurotrophic treatment. Before and after treatment, Toronto Clinical Neuropathy Score, Michigan Diabetic Neuropathy Score, and combined foot score were compared between the combined treatment and single treatment groups. The curative effect was also compared between the two groups. Results:After 4 weeks of treatment, Toronto Clinical Neuropathy Score [(5.82 ± 0.57) points, (7.62 ± 0.89) points], Michigan Diabetic Neuropathy Score [(14.92 ± 2.16) points, (18.01 ± 2.87) points], combined foot score [(3.17 ± 0.49) points, (4.41 ± 0.52) points] in the combined treatment and single treatment groups were significantly lower than those before treatment [(9.84 ± 1.27) points, (9.65 ± 1.21) points, (23.09 ± 4.03) points, (22.81 ± 3.92) points, (5.62 ± 0.85) points, (5.76 ± 0.73) points, t = 3.137, 2.361, 2.952, 2.392, 3.341, 2.427, all P < 0.05]. The declines in the combined treatment group were significantly greater than those in the single treatment group (all P < 0.05). Total effective rate in the combined treatment group was significantly higher than that in the single treatment group (94.74% vs. 78.95%, χ2 = 4.150, P < 0.05). Conclusion:Chinese medicine foot bath combined with foot massage is effective for DPN, which can significantly improve the clinical symptoms and promote the recovery of neurological function.
7.Effect of hemorheology on ultrasonic doppler blood flow spectrum diagram.
Journal of Biomedical Engineering 2014;31(4):798-800
The present research aims to point out the long-existing defect of analyzing the spectrum diagram only from the perspective of haemodynamics instead of haemorheology. In the light of the theories of haemodynamics and haemorheology, the causes of spectrum diagram formation of carotid artery blood at the rapid and slow flow can be clarified completely and accurately. Four conclusions have been drawn in the end. As long as the velocity gradient is large enough, obvious red blood cells concentrate to the shaft even in the big or bigger blood vessels; the spectrum diagram is the powerful proof of the two phase flow model of blood; the spectrum diagram can be completely and accurately analyzed only by combining haemodynamics with haemorheology; and only when the red blood cells concentrate to the shaft, the big or bigger blood vessels can be regarded as haemogeneous fluid.
