Objective To explore relationship among different degrees of hypertension and plasma homocysteine and their clinical significance. Methods According to ,95 hypertension patients were collected and divided into mild,moderate and severe groups,65 patients from the healthy check-up selected as control group, then the plasma Hcy level was measured and compared between the groups. Results Compared with the normal group ( 12. 5 ± 3. 1 ) μ mol/L, Hcy plasma levels of mild ( 15.4 ± 4. 8 ) μmol/L ( t = - 4. 543, P ＜ 0. 01 ), moderate ( 23.2 ± 5. 6 ) μmol/L ( t = - 14. 291, P ＜ 0. 01 ), severe (28. 1 ± 6. 7) μmol/L( t = - 18. 090,P ＜0. 01 ) hypertension group increased significantly,severe group was obviously higher than patients among moderate group,moderate group was significantly higher than patients among mild group,statistical significance among different groups were found( F = 118. 550, P ＜ 0. 01 ). Conclusion High Hcy was an important independent risk factor,the monitoring of plasma homocysteine level for hypertension contribute to diagnosis and understand disease progression.

Objective To investigate the expression of Notch pathway in the kidney of diabetic nephropathy (DN) rats and the intervention effect of Chinese materia medica (CMM) for dispersing blood stasis and dredging collateral. Methods Sixty male Sprague-Dawley rats, in which ten rats were randomly selected as control group (n = 10), and the other rats were fed with high glucose and high fat diet combined with low-dose streptozotocin (STZ) ip injection as DN models. The model rats were randomly divided into model group, irbesartan group, and Huayu Tongluo Granles (HTG) group. The rats in each group were ig administered with corresponding drugs. At the end of the 16 weeks, the 24 h urinary protein was detected. The expression of Notch1, Jagged1, and Hey1 mRNA and protein in renal tissue was detected by real-time PCR, and immunohistochemical staining and western blotting assay, respectively. Results Compared with the control group, 24 h urinary protein, the mRNA and protein expression of Notch1, Jagged1, and Hey1 in model group was significantly increased (P < 0.01). Compared with the model group, 24 h urinary protein and Notch1, Jagged1, Hey1 mRNA, and protein expression of HTG group and irbesartan group was significantly decreased (P < 0.01). Conclusion CMM for dispersing blood stasis and dredging collateral can reduce 24 h urinary protein in DN rats and inhibit the high expression of Notch1, Jagged1, and Hey1 in the kidney tissue of DN rats, which may be one of the main ways to reduce proteinuria excretion.

Thromboembolic diseases are major health problems worldwide,and remain the leading cause of mortality and disabil-ity at present.Bleeding is the most important complication of an-tithrombotic therapy for thromboembolism,therefore research and development of new antithrombotic drugs with lowered bleeding risk is a significant medical need.The data that elevated plasma levels of FXI are associated with thromboembolic diseases,se-vere FXI deficiency reduced incidence of DVT and ischemic stroke,and FXI deficiency or inhibition in animals shows protec-tive effects against thrombus formation supporting FXI as a novel antithrombotic target with lowered bleeding risk.This paper re-views the progress on FXI as a novel antithrombotic target and the inhibitors target FXI.

Objective To explore the changes of expression levels of 12S rRNA and cytochrome oxidase subunit Ⅰ (COXⅠ) mRNA encoded by mtDNA in rat cerebral cortex after rat exposure to hypobaric hypoxia for different days. Methods Healthy male Wistar rats were exposed to hypobaric chamber simulating 5 000 m above sea level (23 5 h/day) for 2, 5, 15 and 30 d. Rats in the control group were not exposed to hypoxia. Rats were sacrificed by decapitation. Total RNA in cerebral cortex was extracted using a standard program. Transcriptional levels of 12S rRNA and COXⅠ mRNA were determined by reverse transcription polymerase chain reaction (RT PCR). Results Compared with that in the control, the expression of 12S rRNA increased by 57% after hypoxic exposure for 2 d ( P 0 05). Compared with that in the control group, the expression of COXⅠ mRNA increased significantly by 55% and 106% after hypoxic exposure for 2 and 5 d ( P 0 05). Conclusion Hypoxic exposure may have effect on both protein gene and ribosome gene expression encoded by mtDNA, and the expression changes in a hypoxic exposure time dependent manner. This suggests that hypoxia can have effect on mitochondrial oxidative phosphorylation gene expression at both mitochondrial transcriptional and translational levels.
