ObjectiveTo explore the protective effect of glucocorticoid-induced transcription factor 1 （GLCCI1） on cognitive dysfunction in diabetic mice and its mechanism. MethodsTwenty-four C57BL/6J mice were randomly divided into 4 groups， namely Control， DM， DM+AAV-Glcci1， and DM+AAV-NC. The Control group was intraperitoneally injected with saline， while the other groups were all injected with streptozotocin （STZ）. Two weeks after successful modeling， the DM+AAV-Glcci1 group was brain stereotactic injected with Glcci1 overexpressing adeno-associated virus， and the DM+AAV-NC group was stereoscopically injected with the control virus. After 12 weeks， the Morris water maze test was used to evaluate the learning and memory abilities of mice in each group. Subsequently， the localized expression of GLCCI1 in the hippocampus were determined by immunofluorescence and immunohistochemistry experiments. The myelin morphology in the hippocampus was observed by LFB staining， the neuronal morphology was observed by Nissl staining， and the myelin-related proteins MBP and CNPase were stained by immunohistochemistry. Molecular docking was used to predict the interaction between GLCCI1 and HSPA5. The expression of endoplasmic reticulum stress-related proteins was detected by Western blot. ResultsThe results of the behavioral experiment showed that compared with the mice in the Control group， DM mice exhibited obvious cognitive dysfunction behaviors （P＜0.000 1）， and the learning and memory abilities of mice improved after overexpression of Glcci1 （P=0.000 7）. The results of immunofluorescence and immunohistochemistry showed that GLCCI1 was expressed in hippocampal neuron cells. Compared with Control mice， the expression level of GLCCI1 in DM mice was significantly downregulated （P＜0.000 1）. The molecular docking results revealed that GLCCI1 interacts with HSPA5. The Western blot results indicated that， compared with the Control group， the expression levels of endoplasmic reticulum stress-related proteins HSPA5 （P＜0.000 1）， ATF4 （P＜0.000 1）， ATF6 （P=0.001 1）， and p-ELF2α/elF2α （P=0.000 1） in the DM group were significantly increased； Compared with the DM group， the expression of the corresponding protein HSPA5 （P＜0.000 1）， ATF4 （P＜0.000 1）， ATF6 （P=0.000 2）， and p-ELF2α/elF2α （P=0.000 1） was significantly down-regulated after overexpression of Glcci1. LFB staining showed that compared with the Control group， the myelin integrity of DM mice decreased significantly （P=0.010 3）， the expressions of myelin-related proteins MBP and CNPase decreased significantly （P=0.000 4， P=0.000 2）， and Nissl staining observed disordered neuronal arrangement. Compared with the mice in the DM group， the myelin integrity in the hippocampal region significantly increased after overexpression of Glcci1 （P=0.000 3）， the expressions of myelin-related proteins MBP and CNPase significantly increased （P=0.001 4， P=0.000 1）， and the ordered arrangement of neurons was observed by Nissl staining. ConclusionThe down-regulation of GLCCI1 expression in hippocampal neurons promotes demyelination of hippocampal neurons and thereby induces diabetic cognitive dysfunction. The specific mechanism may be related to endoplasmic reticulum stress.

Objective To investigate the efficacy of Amplatzer duct occluder-Ⅱ device(ADO-Ⅱ)in treating ventricular septal detect(VSD)with aortic sinus prolapse(ASP)in child patients.Methods The clinical data of 94 child patients with VSD complicated by ASP,who were admitted to the Hunan Provincial Children's Hospital of China between January 2018 and September 2022,were retrospectively collected.The child patients included 60 males and 34 females with a mean age of(4.7±3.1)years.Mild-moderate ASP was seen in 83 child patients,with a mean(4.12±0.97)mm-sized VSD.Severe ASP was seen in 11 child patients,with a mean(4.95±0.51)mm-sized VSD.Perimembrane VSD was observed in 54 child patients and intracristal VSD in 40 child patients.The relationship of VSD size and degree of ASP to the selection of ADO-Ⅱ,postoperative middle period aortic valve regurgitation and residual leakage was analyzed,so as to clarify the applicability of ADO-Ⅱ to such child patients.Results In the postoperative middle period,6 child patients had mild aortic valve regurgitation,most seen in the child patients who received 4-4 mm or 5-4 mm ADO-occluder;and 10 child patients had residual leakage,mainly seen in the child patients who received 5-4 mm or 6-4 mm occluder.Conclusion In the condition when the ADO-Ⅱ occluder shows satisfactory placement pattern,this treatment is suitable for the child patient having＜6 mm VSD with ASP.Although there are some residual leakage and aortic valve regurgitation after surgery,this interventional therapy still meets the clinical requirements.(J Intervent Radiol,2024,32:17-21)

Objective To observe the efficacy and safety of sacubitril valsartan in the treatment of dilated cardiomyopathy (DCM) in children. Methods A total of 19 hospitalized children with DCM were retrospectively selected as study subjects. All patients received captopril combined with conventional anti-heart failure therapy for 1 to 4 weeks, but due to ineffective treatment, they were switched to treatment of sacubitril valsartan. Clinical data, biochemical indicators, and echocardiographic findings were collected to assess changes in clinical symptoms and related indicators after 1-, 3-, 6-, and 12-month sacubitril valsartan treatment. Information on the dosage and administration of sacubitril valsartan, as well as the occurrence of adverse reactions was collected. Results Among 19 patients, there were 8 males and 11 females, with a median age of 3 years. Heart function was classified as grade Ⅱ in 2 patients, grade Ⅲ in 10 patients, and grade Ⅳ in 7 patients. At the final follow-up, the efficacy assessment showed significant improvement in 8 patients, effective improvement in 6 patients, and no improvement in 5 patients, with a total effective rate of 73.7%. After 1-, 3-, 6-, and 12-month sacubitril valsartan treatment, the levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) were lower, left ventricular ejection fraction (LVEF) was higher, and left ventricular diastolic diameter (LVDd)-Z value was smaller compared with those before treatment (P < 0.05). The initial single dose of sacubitril valsartan was 0.8 mg/kg, and the average maintenance dose was 1.7 mg/kg, administered twice daily. After treatment, 1 patient developed hypotension, and 5 patients exhibited mild abnormalities in renal function indicators (of which 4 recovered to normal levels after tolerance). Conclusion Sacubitril valsartan can effectively improve heart failure symptoms and cardiac function indicators in children with DCM, but close monitoring of blood pressure and renal function changes is required during treatment.

Objective To investigate the expression of calpain small subunit 1 (Capn4) in breast cancer and its clinical significance. Methods The cancer tissues and the paraffin-embeded specimens of the corresponding adjacent normal tissues from 12 patients with breast cancer between May 2015 and July 2015 in Shanghai General Hospital were collected. The expression of Capn4 was detected by using immunohistochemistry. The paraffin-embeded specimens of cancer tissues from 70 breast cancer patients in Shanghai General Hospital between January 2009 and September 2011 were also collected. And the expression of Capn4 was detected. The correlation between Capn4 expression level and TNM stage, pathological grade, molecular markers as well as the prognosis of breast cancer was also analyzed. Results The expression of Capn4 in breast cancer tissues was higher than that in the corresponding adjacent normal tissues. The expression level of Capn4 was correlated with TNM stage (P = 0.002), T stage (P = 0.004), N stage (P = 0.004), M stage (P = 0.025), estrogen receptor (ER) status (χ 2 = 4.787, P = 0.029) and survival status (χ 2 = 5.826, P = 0.016). Kaplan-Meier survival analysis revealed that the median survival time in the higher expression of Capn4 group 90 months was shorter than that in the lower expression of Capn4 group (not reaching the median survival time), and there were statistical differences (χ 2 = 4.351, P = 0.037). Conclusions The expression of Capn4 in breast cancer tissues is upregulated. The expression difference is correlated with TNM stage, pathological grade, ER status and the prognosis of breast cancer, suggesting that it may become a new target and molecular marker for breast cancer treatment.
