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 To evaluate the effect of LCVP applied during the operation of hepatectomy.Methods Sixty patients underwent hepatectomy were enrolled in the study from March 2010 to March 2012 in our hospital which were randomized into LCVP group and normal CVP (NCVP) group by the sealed envelope method. CVP was kept<0.5 kPa during entire procedure of hepatectomy in LCVP group, and the value of CVP and blood pressure were controlled within 10% of the baseline. The same anesthesia, incision and hepatectomy technique and indications of blood transfusion in LCVP group were undertaken as those in NCVP group.

Objective By discussing the accuracy of A-scan and IOL Master in intraocular lens power measurement, to offer Objective clinical data for cataract surgery.Methods Three hundred patients(300 eyes)with age-related cataract were included in the study. Before surgery,axial length was measured by A-scan and IOL Master respectively and corneal curvature was measured by auto refractometer. A-scan group used the corneal curvature data of the auto refractometer. IOL Master group used the corneal curvature data from the instrument. Intraocular lens power was calculated according to the SRK-T formula.We observed the refractive state of 3m after operation, detected and analyzed the patient's refractive data by the auto refractometer.Results All patients who were included in the study were randomly divided into A-scan group and IOL Master group.The mean axial length was (23.21±0.59) mm measured by A-scan, the mean axial length was (23.22±0.59) mm measured by IOL Master. There was no significant difference between them (P>0.05). The preoperative mean corneal curvature measured by the auto refractometer was (44.01±1.79)D. The preoperative mean corneal curvature measured by IOL Master was (44.13±1.62)D. There was no statistically significant difference between them (P＞0.05). The mean absolute refractive error ( MAE) in A－scan group was (0.43±0.26)D and in IOL Master group was (0.42±0.17)D. There was no statistically significant difference between them (P＞0. 05).Conclusion IOL Master group operated slightly better than A-scan group, but we did not find a significant advantage in intraocular lens power measurement with A-scan group. IOL Master may not completely replace A-scan. The combination of the two ensures the accuracy of the measurement in intraocular lens power.
