The extracted and purified ferulic acid residue from Radix angelicae sinensis was quantified by an established HPLC system composed of the following conditions: reversed phase column C-18 Purosphere 4.6mm 1D x 250 mm (5mm); mobile phase: acetonitrile/potassium dihydrophosphate 10 mM/L (15/85); pH: 4.5; flow rate: 1.2 mL/min; column temperature: 30oC. The results showed that the method can meet the following criteria: Rs > 1.5, RSD < 2%, N > 1 000, Tf in the range 0.8-1.2

A study on 104 patients with chronic renal failure due to the obstructed urethral stone has shown that this disease in Vietnam was very severe, the nepthrotic creatinine clearance of 10ml/min occurred in 36 patients. The water, electrolyte and acid-base balance were severe. The recovering ability of morphism and rest function of patients with the chronic renal failure was high. A rest of patients that renal function can not be recovered mainly cause by large renal parenchymal lesions. The rest of nephron was very small that can not meet the function of endothelial balance. The patients should receive the kidney transplantation and periodical hemodialysis.

E.coli endotoxin in septic shock causes hypotension, multiple organ dysfunction, and left ventricular change with characteristic of the myocardiac depression. There is no longer any doubt that continuous hemofiltration in the therapies is better tolerated when comparing with intermittent hemodialyin. In the blood, concentration of the myocardial depressant factor was reduced by half in the first hour of extracorporeal removal. Continuous hemofiltration will be used in septic shock as soon as for the patient is oliguric and hemodynamical unstable.

A development trial and application of non-scalpel vasectomy on 3850 men more than 30 ages in the whole country during 1992-1993 has shown that it was a simple technique and easy to implement and train. The technical condition was very simple, only required a septic room and 3 basic medical equipments scissors and pincers. The complication of traditional technique and non-scalpel vasectomy was 3% and 0,63%, respectively. The revasectomy was simple, and can be implemented out of hospital.
