目的 本研究从细胞生物学角度检测二甲双胍对小鼠胰岛瘤MIN6的影响,并探讨此过程中包含的分子生物学机制。方法 MTT法检测不同浓度二甲双胍(1、2、5、10、20 mmol/L)对MIN6细胞活力的影响,细胞划痕实验检测二甲双胍对MIN6细胞迁移的影响,免疫印记实验检测此过程中细胞凋亡相关蛋白Bcl-2、Bax、caspase3表达的变化,及AMPK和JNK信号通路蛋白磷酸化水平的变化。结果 二甲双胍浓度大于10 mmol/L时可以抑制MIN6细胞的活力(P<0.01),降低其迁移能力(P<0.01),高浓度二甲双胍可以上调细胞内凋亡蛋白Bax(P<0.05)和p-AMPK的表达(P<0.05),降低抗凋亡蛋白Bcl-2的表达,增加caspase3剪切体(P<0.05)。同时,二甲双胍可以降低MIN6细胞内JNK信号通路的磷酸化水平(P<0.05)。结论 高浓度二甲双胍可以抑制MIN6细胞的增殖和迁移,其作用可能与降低了JNK信号的通路活化有关。
Objective This study aims to investigate the effect of metformin on proliferation and migration of MIN6 cells, and to explore the underlying mechanism. Methods The viability of MIN6 cells that were treated with various metformin (1,2,5,10 and 20 mmol/L) was detected by MTT assay. The migration of MIN6 cells was determined by wound-healing assay. Meanwhile, the proteins expression of Bcl-2, Bax, caspase3 and the phosphorylation of AMPK, JNK was detected by western bolt assay. Results The cell viability and the migration of MIN6 cells were decreased when the concentration of metformin above 10 mmol/L(P<0.01). The expression of apoptosis-related protein Bax(P<0.05) and p-AMPK(P<0.05)was up-regulated, anti-apoptosis-related protein Bcl-2 was down-regulated and cleaved caspase3 (P<0.05)was increased after high metformin treatment. At the same time, the phosphorylation of JNK was down-regulated by metformin(P<0.05). Conclusion High concertration of metformin may inhibit the proliferation and migration of MIN6 cells through suppressing the activation of JNK signaling pathway.

Objective: Discussion on diagnosis of testicular non-tumorous lesions by ultrasound and CT.Methods: Rretrospective analysis of 58 testicular non-tumor cases proved by clinical history, Ultrasound, CT or pathologically,combined with the clinical history, and analysis of the Ultrasound and CT features,including inflammatory or infectious disease, traumatic disease, congenital disease and acute torsion.Results: All cases were examined by CT,the testicular inflammatory lesions were 39 cases, 19 of them were examined by ultrasound; testicular trauma 8 cases,cryptorchidism 9 cases, testicular torsion in 2 cases, all of them were examined by ultrasound. The clinical symptom of the inflammatory lesions of the ipsilateral or bilateral scrotum with different degrees of red, swollen, painful, or leukocytosis, other organs associated with TB, Ultrasound showed the testicular volume increased to varying degrees,according to the degree of inflammation and necrosis, the echo showed homogeneous echo, echo reduction, echo heterogeneity, and no blood flow signal in the necrotic area.CT showed an increase in testicular volume, according to the different inflammatory lesions showed mild enhancement of testis, ring enhancement, with a hydrocele, calcification or gas; testicular trauma had scrotal trauma history, according to the severity of injury showed subcapsular hematoma, hemorrhage and rupture of testis; testicular cryptorchidism showed abnormal position or absent; testicular torsion showed testicular short time severe pain, and progressive, Ultrasound showed “bracelet ring sign”, CT showed testicular torsion, edema, testicular parenchyma edema.Conclusion: Ultrasound and CT features of testicular non-tumorous lesions are characteristic, and the accurate diagnosis can be made with the combination of the patient's clinical history. Ultrasound examination is more convenient, CT examination can relieve the patient's contact pain, can be more comprehensive observation of the pelvic and abdominal.
