From the total alkaloids of the root of Kopsia lainanensis Tsiang, eight compounds were isolatcd and identificd as coronaridine (Ⅰ), heyneaninc (Ⅱ), tabersonine (Ⅲ), 11-methoxytabersonine (Ⅳ), scandine (Ⅴ), N-methoxycarbonyl-11, 12-methylenedioxykopsinaline (Ⅵ), kopsinine (Ⅶ) and N-methoxycarbonyl-12-methoxykopsinaline (Ⅷ) by means of physical constants and spectral analysis

OBJECTIVE: To study the dissolution amounts of aciclovir (ACV) from differently based preparations and provide the evidence for the development of new preparation of ACV. METHOD: The dissolution tester was applied for the quantitative determination of ACV released from 3 based formulations and 5 concentrations samples. The release amount per unit area (M) and the accumulative release percentage (Q) were compared respectively. RESULTS: The value for M was raised with the increase of the concentration of aciclovir in preparations, and for Q was reduced. The release rates of the aciclovir gel were at least two times faster than the creams and the ointment. CONCLUSION: The drug dissolution from ACV gel was better than the creams and the ointment. 10 gkg-1 ACV in prearation was the suitable concentration.

Objective To evaluate the effect of direct stenting on no-reflow in patients with ST-segment elevation (STEMI) acute myocardial infarction. Methods A total of 157 patients with STEMI received direct stenting (DS,n=85) or conventional post-dilation stenting (CS,n=72). The time of X-ray exposure, the amount of contrast media consumed, the TIMI grading after stenting and ST-segment changes of electrocardiogram were compared between two groups. Results The time of X-ray exposure and the amount of contrast media consumed were significantly less in DS group than those in CS group [(24.6?16.9) min vs (34.4?17.5) min, (115?37) mL vs (166?61) mL, P

Objective To investigate the significance of symptom-to-ballon time on patients with ST elevation acute myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). Methods 171 patients, in which ANGIOGUARD XP distal protection devices were applied in 18 patients, were divided into three groups according to their symptom-to-ballon time: group A (

OBJECTIVE:To screen the effective antioxidant in tretinion ointment METHODS:The six tretinion ointments were prepared with different antioxidants and the same base Based on the accelerated test design,the tretinion concentration was determined by HPLC RESULTS:The ointment with the antioxidant D exhibited the least oxidation rate CONCLUSION:Data from accelerated test demonstrated that the compound antioxidant D was the best one in this formula

The screw holes of anatomic plate are oval, and longitudinal axis of the screw hole is parallel to the axis of the plate. The plate surrounding the screw hole is smooth, parallel to the longitudinal axis of the long bone. Under outside force or inside force, the top of screw can move on the smooth surface surrounding the screw hole; the movement is a reversible one. Domestic plate can fix bone fracture stably, and the outside force and inside force can result in micromovement of the fracture ends, stimulating the fracture ends and bone callus formation. Repetitive force is beneficial to bone callus response, protect fragile new vessels and bone trabecula from damage, and promote fracture healing.
