【摘 要】目的: 调查肠造口患者病耻感与出院准备度现状,并探讨两者相关性。方法: 选取北京协和医院结直肠外科行肠造口术住院患者 124 例,采用出院准备度量表 ( RHDS) 评价出院准备度状况,用社会影响量表 ( SIS) 评价病耻感状况。结果: 居住在农村的患者 SIS 得分高于居住在城市的患者,家庭月均收入≤3000 元的患者 SIS 高于家庭月均收入 > 3000 元的患者 ( 均 P < 0. 05) 。患者 SIS 总分及各维度得分均与 RHDS 总分呈负相关 ( r = - 0. 35、 - 0. 31、 - 0. 26、 - 0. 32、 - 0. 36,均 P < 0. 01) 。多重回归分析显示 SIS 的内在羞耻感维度得分与 RHDS 总分负向关联 ( β = - 3. 33,P < 0. 05) 。结论: 肠造口患者病耻感与出院准备度密切相关。

Background: Glycolysis dysfunction is an important pathogenesis of podocyte injury in diabetic kidney disease (DKD). Foot process fusion of podocytes and increased albuminuria are markers of early DKD. Moreover, cytoskeletal remodeling has been found to be involved in the foot process fusion of podocytes. However, the connections between cytoskeletal remodeling and alterations of glycolysis in podocytes in DKD have not been clarifified.

Methods: mRNA sequencing of glomeruli obtained from db/db and db/m mice with albuminuria was performed to analyze the expression profifiling of genes in glucose metabolism. Expressions of phosphofructokinase platelet type (PFKP) in the glomeruli of DKD patients were detected. Clotrimazole (CTZ) was used to explore the renal effects of PFKP inhibition in diabetic mice. Using Pfkp siRNA or recombinant plasmid to manipulate PFKP expression, the effects of PFKP on high glucose (HG) induced podocyte damage were assessed in vitro. The levels of fructose-1,6-bisphosphate (FBP) were measured. Targeted metabolomics was performed to observe the alterations of the metabolites in glucose metabolism after HG stimulation. Furthermore, aldolase type b (Aldob) siRNA or recombinant plasmid were applied to evaluate the inflfluence of FBP level alteration on podocytes. FBP was directly added to podocyte culture media. Db/db mice were treated with FBP to investigate its effects on their kidney.

Results: mRNA sequencing showed that glycolysis enzyme genes were altered, characterized by upregulation of upstream genes (Hk1, and Pfkp) and down-regulation of downstream genes of glycolysis (Pkm, and Ldha). Moreover, the expression of PFKP was increased in glomeruli of DKD patients. The CTZ group presented more severe renal damage In vitro, the Pfkp siRNA group and ALDOB overexpression group showed much more induced cytoskeletal remodeling in podocytes, while overexpression of PFKP and suppression of ALDOB in vitro rescued podocytes from cytoskeletal remodeling through regulation of FBP levels and inhibition of the RhoA/ROCK1 pathway. Furthermore, targeted metabolomics showed FBP level was signifificantly increased in HG group compared with the control group. Exogenous FBP addition reduced podocyte cytoskeletal remodeling and renal damage of db/db mice.

Conclusions: These fifindings provide evidence that PFKP may be a potential target for podocyte injury in DN and provide a rationale for applying podocyte glycolysis enhancing agents in patients with DKD.
