Objective To detect CYP2J3 gene expression and contents of 11,12-EET in heart,liver,lung,kidney and aorta thoracalis after CYP2J3 gene transfection.Methods The rat transgenic model was developed by injecting plasmid through vena dorsalis penis.The animals were divided into control group、 pcDNA3.1 transgenic group and pcDNA3.1-CYP2J3 transgenic group.The expression of CYP2J3 mRNA was detected by RT-PCR and content of 11,12-EET was examined by the HPLC at 14 days and 28 days after injection.Results Twenty eight days after injection,both expression of CYP2J3 mRNA and the content of 11,12-EET were significantly increased as compared with that of control and pcDNA3.1 transgenic group(P

Objective To study the clinical effect of total parathyroidectomy with subcutaneous autotransplantation (TPTX + AT) in the treatment of secondary hyperparathyroidism(SHPT) in patients with chronic renal failure.Methods One hundred and thirty-four patients undergoing TPTX + AT in our hospital from January 2013 to October 2014 were includud in this study.The preoperative,postoperative and follow-up intact parathyroid hormone (iPTH),serum calcium,serum phosphorus and calcium-phosphorus product were statistically analyzed.The Kidney Disease Quality of Life Short Form (KDQOL-SFTM) scale was used to evaluate quality of life before and one year after parathyroidectomy.Postoperative complications and recurrence were observed.Results Postoperative iPTH,serum calcium,serum phosphorus and calciumphosphorus product decreased significantly compared with that before surgery.The difference had statistical significance (all P ＜ 0.05).One patient died in perioperative period.Temporary injury of recurrent laryngeal nerve was found in eight patients.Early postoperative hypocalcemia was frequently seen in 124 patients (92.5％) and in 7 cases (5.2％) occured intractable hypocalcemia.The quality of life was significantly improved one year after parathyroidectomy.Recurrence developed in 5 patients after operation.Conclusions TPTX + AT is safe and effective in the treatment of SHPT in patients with chronic renal failure and can significantly improve the patient's quality of life.

Objective To investigate the correlation between microembolic signal (MES) and immune inflammation in patients with acute ischemic stroke. Methods The consecutive patients with acute ischemic stroke were enroled. According to the results of MES, they were divided into either a positive group or a negative group. The Immune inflammatory indexes, demographics, and baseline clinical data in both groups were compared. Multivariate logistic regression analysis was used to analyze the independent influencing factors of MES in acute ischemic stroke. Results A total of 237 patients were enroled, including 52 in the MES positive group and 185 in the MES negative group. There were significant differences in the levels of triglyceride (2. 130 ± 0. 933 mmol/L vs. 1. 811 ± 0. 962 mmol/L; t = 2. 126, P = 0. 035), plasma fibrinogen (2. 946 ± 0. 255 g/L vs. 2. 833 ± 0. 322 g/L; t = 2. 332, P = 0. 021 ), Lp-PLA2 level ( 288. 265 ± 27. 855 μg/L vs. 261. 652 ± 29. 961 μg/L; t = 2. 897, P = 0. 004 ), as wel as the proportions of CD4 + CD25high Treg (8. 695% ± 1. 461% vs. 9. 445% ± 1. 397% ; t = 3. 386, P = 0. 001), artery stenosis ≥70% (21. 15% vs. 5. 41% ; χ2 = 10. 592, P = 0. 001 ) and smal arterial occlusive stroke (9. 62% vs. 23. 24% ; χ2 = 4.667, P = 0. 031) between the MES positive group and the MES negative group. Multivariate logistic regression analysis showed that the increased plasma fibrinogen level (odds ratio [OR] 3. 257, 95%confidence interval [CI] 1. 124 - 9. 438; P = 0. 030), artery stenosis ≥ 70% (OR 3. 585, 95% CI 1. 394 -9. 219; P = 0. 008), and the decreased ratio of Treg (OR 3. 801, 95% CI 1. 190 - 12. 148; P = 0. 024) were the independent risk factors for positive MES, and smal arterial occlusive stroke was its independent protective factor (OR 0. 244, 95% CI 0. 072 - 0. 829; P = 0. 024). Conclusions MES may be associated with immune inflammation. The relationship between stroke and immune inflammation should be taken seriously.
