As one of the most sensitive cells of endoplasmic retieulum stress (ERS), pancreatic β-cells have an a-bundance of endoplasmic reticulum. Fatty acids cause apoptosis of β-cells and might contribute to β-cell loss in type 2 diabetes mellitus via the induction of ERS. Glucose is an amplifier of the ERS response to fatty acid, leading to increased β-cell apoptosis. ERS response mediates glucolipotoxicity-induced β-cell apoptosis.

Objective To study the correlation between ths DSA manifestations and expression of serum VEGF in the patients with cervical cancer.Methods Imaging data of 40 cases with cervical cancer confirmed by clinic were collected,and DSA were performed during interventional therapy in all cases,and the serum VEGF was detected by enzyme-linked immunosorbent assay(ELISA)which was compared with that in 40 healthy women as contrast.Results(1)Serum VEGF level in the patients with cervical cancer was significantly higher than that in control group(P＜0.01),and the serum VEGF level was significantly higher in Ⅲ and Ⅳ stage of cervical cancer than that in Ⅱ stage(P＜0.05).(2)There was positive correlation between tumor stain in DSA and the serum level of VEGF(P＜0.05).Conclusion There was positive correlation between the degree of blood supply and the serum level of VEGF.

Objective To observe the effect of sitagliptin combined with insulin aspart 30 in the treatment of secondary failure of sulphonylurea in type 2 diabetes mellitus. Methods Fifty-six cases were divided into group A and group B in random block design, with 28 cases of each group. The patients in group A was treated with sitagliptin combined with insulin aspart 30, while the patients in group B was given subcutaneous injection of insulin aspart 30R. All patients were treated for 12 weeks. Fasting plasma glucose(FPG), 2-hour postprandial plasma glucose(2 hPG), glycosylated hemeglobin(HbA1c), insulin secretion index (HOMA-β), body mass index (BMI), and incidence of low blood glucose before and after treatment were compared. Results Compared with that in group B, FPG [(5.61 ± 1.14) mmol/L vs. (7.8 ± 1.22) mmol/L], 2 hPG [(7.62 ± 1.35) mmol/L vs(9.72 ± 1.41) mmol/L] and HbA1c [(7.11 ± 0.83)%vs.(8.32 ± 1.04)%] in group A had a significant decrease;HOMA-β[(50.31 ± 5.12) vs. (41.86 ± 4.53)] of group A was higher than that of group B (P

Objective To investigate whether terminal QRS distortion on the electrocardiogram in acute inferior myocardial infarction could be as a standard for the infarct-related artery,through comparing to coronary angiography.Methods Fifty-seven patients with acute inferior myocardial infarction were enrolled,among which,the right coronary artery (RCA) occlusion (RCA occlusion group) was present in 29 cases,and left circumflex coronary artery (LCX) occlusion (LCX occlusion group) was in 28 cases.The changes of electrocardiogram was analyzed in 12 hours after the acute episode.Results The incidence of terminal QRS distortion in leads Ⅱ,Ⅲ,aVF in RCA occlusion group was 44.8％(13/29) and 39.3％(11/28)in LCX occlusion group,and there was no significant difference (P ＞ 0.05).The incidence of terminal QRS distortion in leads V4R-V5R in RCA occlusion group was 17.2％(5/29) and 7.1％(2/28) in LCX occlusion group,and there was no significant difference (P ＞ 0.05).The incidence of terminal QRS distortion in leads V7-V9 in RCA occlusion group was 6.9％(2/29),which was lower than that in LCX occlusion group[53.6％(15/28)],and there was significant difference (P ＜ 0.05).For identifying LCX as the infarct-related artery of acute inferior myocardial infarction,the sensitivity,specificity,positive and negative value in terminal QRS distortion in leads V7-V9 were 53.6％ (15/28),93.1％ (27/29),88.2％ (15/17),67.5％ (27/40).The area under curve of terminal QRS distortion in leads V7-V9 in identifying LCX as the infarct-related artery of acute inferior myocardial infarction was 0.733 (95％ CI 0.599-0.868).Conclusion Terminal QRS distortion in leads V7-V9 may be of diagnostic value in identifying the infarct-related artery in acute inferior myocardial infarction.

Basic fibroblast growth factor(bFGF)is a polypeptide cell growth factor,which has exten- sive physiological functions.With the in-depth study,the exploration of relationship between basic fibroblast growth factor and tumor has been developing rapidly in recent years,It shows a good prospect in diagnosis and treatment of tumor.There is a brief overview about the molecular biology of bFGF,its expression in tumor and the relationship between bFGF and tumorigenesis.

Objective To evaluate the surgical technique and clinical application of retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy with no suture of the incision. Methods Twenty-five patients who had upper urinary tract calculi with the course from 10 months to 6 years were enrolled.The size of the calculi was 1.2 to 3.1 cm in diameter.ESWL was ineffecative in 14 of the patients and ureteroscopic lithotomy failed in 2 of them.Then the 25 patients underwent retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy.Details of the procedure were presented. Results All the operations were successful in the 25 patients. The operations took 60 to 190 min with a mean time of 105 min.All the patients fully recovered with no complication observed during the 9～12 months' follow-up. Conclusions Retroperitoneal laparoscopy surgery with no suture of the incision has advantages of minimal invasive,safe,effective and rapid postoperative rehabilitation.The surgical procedure has a good prospect in the urologic clinical practice.
