ABSTRACT

Objective:To investigate the changes and clinical significance of gastrin 17 (G-17) in patients with diabetic nephropathy (DN).Methods:One hundred and twenty-four DN patients admitted to Hefei Second People′s Hospital from July 2018 to December 2020 were selected as the DN group, and divided into Ⅰ-Ⅱstage subgroup (68 cases) and Ⅲ-Ⅴ stage subgroup (56 cases) according to the stage of DN.Inaddition, 100 cases of type 2 diabetes mellitus(T2DM) patients without DN were selected as the T2DM group, and 100 healthy subjects who examined during the same period were selected as the control group. The levels of G-17, serum creatinine (SCr), evaluated glomerular filtration rate (eGFR) and other index in each group were detected. The normal level of G-17 was 1-7 pmol/L. G-17>7 pmol/L and ≤ 15 pmol/L was as marginal rising, and G-17>15 pmol/L was as rising.Results:The marginal rising rate of G-17 in the DN group was higher than that in the T2DM group: 43.5%(54/124) vs. 23.0%(23/100); the rising rate of G-17 in the DN group was higher than that in the T2DM group and the control group: 21.0%(26/124) vs. 7.0%(7/100), 4.0%(4/100), and the differences were statistically significant ( P<0.05). The marginal rising rate and rising rate of G-17 in Ⅲ-Ⅴstage subgroup were both higher than those in the Ⅰ-Ⅱ stage subgroup and the T2DM group: 58.9%(33/56) vs. 30.9%(21/68), 23.0%(23/100); 32.1%(18/56) vs. 11.8%(8/68), 7.0%(7/100), and the differences were statistically significant ( P<0.05). The marginal rising rate and rising rate of G-17 in DN patients with a disease course of ≥3 years was higher than that in patients with a disease course of <3 years and the T2DM group: 53.0%(44/83) vs. 24.4%(10/41), 23.0%(23/100); 27.7%(23/83) vs. 7.3%(3/41), 7.0%(7/100), and the differences were statistically significant ( P<0.05). Correlation analysis showed that G-17 was positively correlated with SCr ( r = 0.367, P<0.001) and negatively correlated with eGFR ( r = -0.619, P<0.001) in DN patients. Conclusions:The level of G-17 in ND patients is significantly increased, which is closely related to DN staging and can provide an auxiliary indicator for screening renal function in patients with T2DM.

ABSTRACT

Wildtype p53-induced phosphatase 1 (Wip1) is a serine/threonine protein phosphatase of 605 ami-no acids, which is expressed at high levels in many organs and tissues .As Wip1 is overexpressed in human tumors , analy-sis of Wip1 has focused primarily on its role in tumorigenesis .In recent years , it has also been shown that Wip 1 plays an important role in several physiological processes including adult neurogenesis , senescence , immunodeficiency and metabolic diseases.This review addresses how Wip1 participates in physiological and pathological conditions at cellular and molecular levels.

ABSTRACT

Objective: To explore the impact of knocking out wildtype p53 phosphatase 1 gene on heart function with the changes of cardiac tissue mRNA and protein expressions in experimental mice. Methods: Our research included in 2 groups: Wildtype (WT) mice group and Wip1 knockout (Wip1-KO) mice group. n=10 in each group. The heart function, ratio of heart weight to body weight (HW/BW) were examined and compared between 2 groups; cardiac tissue morphology was observed by HE staining; mRNA expressions of ANP, BNP, MCP-1 andα-SMA were determined by RT-PCR and protein expressions of Bcl-2, Bax and c-caspase3 were measured by Western blot analysis. Results: Compared with WT mice group, Wip1-KO mice group showed decreased Wip1 mRNA expression,P0.05; apoptosis related protein expressions of Bax/Bcl-2 and c-caspase3 were similar between 2 groups,P>0.05. Conclusion: Wip1 gene knockout may impair the heart function in experimental mice, while the relevant mechanism should be further investigated.

ABSTRACT

To explore the association between polymorphisms of transcription factor 7-like 2 gene (TCF7L2) and type 2 diabetes mellitus in Hefei district. The results suggest that the genetic variation DG10S478 in the TCF7L2 gene was not associated with type 2 diabetes mellitus in Hefei district ( P>0.05 ). However, its attribution to the susceptibility of type 2 diabetes mellitus in Hefei is not important.
