Objective To investigate the effect of folic acid intervention on plasma homocysteine (Hcy) metabolic changes and pulse wave velocity(PWV)in patients with type H hypertension. Methods Patients(hos-pitalized from March 2014 to December in our hospital)with H type hypertension were randomly divided into treat-ment group and control group randomly ,and were given routine antihypertensive drug therapy. Treatment group was given oral folic acid 0.8 mg,1 times a day,the control group was given placebo,1 times a day. All patient were treated for 12 months. Changes of plasma Hcy and PWV levels were observed. Results 432 patients(Han nationality)with type H hypertension were enrolled in this study with the age of 61.7 ± 13.6 years old and the ratio of men and women is 1.3:1. The most common diseases were coronary heart disease and type 2 diabetes mellitus. 2 groups were treated for a period of 12 months,with follow-up time from 6 to 10 months(average duration in 8 months). After treatment,the difference between plasma Hcy(Z=-7.63,P=0.000)and PWV(Z=-3.16,P=0.002)levels of the two groups were statistically significant. Conclusion Folic acid intervention can significantly reduce the level of plasma Hcy in patients with type H hypertension ,slow down the progression of atherosclerosis and reduce the risk factors of cardiovascular disease.

OBJECTIVESTo summarize the clinical experience of preoperative intraarterial chemotherapy (PRAC) and evaluate the long-term results of multimodality against colorectal cancer.
METHODSSeldinger procedure was used to intubate the tube to the artery branch which supplied blood to the tumor. The tumor was imaged to make sure the diagnosis and irrigate the chemotherapeutic drugs. Ten days after PRAC, the patients received radical operation and 6 chemotherapeutic courses with FCF regimen. Concurrent patients receiving surgical treatment yet no PRAC therapy were chosen as controls.
RESULTSOne-year survival rate was 93.05% in the PRAC group and 80.78% in the controls (P = 0.023). COX multivariate analysis was used to analyse the prognostic factors. Dukes'staging and the PRAC prescription or not were found to be independent prognostic factors of colorectal cancer patients. Patients in the PRAC group survived longer than those in the control group.
CONCLUSIONPRAC can improve the survival of colorectal cancer patients.
