ABSTRACT
The study mainly describes the research progress of domestic identification of similar Chinese medicinal plants and the research progress of foreign identification of similar plants, placing emphasis on the principle, merits and defects of new technology and methods including plant biotechnology, spectral identification technology and computer vision technology. With the continuous update of science and technology, the accuracy of identification of similar Chinese herbal medicine plants has been improved, and the rapid progress of identification of Chinese herbal medicine plants has been promoted. The paper mainly elaborated the latest development of plant identification technology of similar Chinese herbal medicines in depth, so as to summarize the principle and characteristics of the new technology and forecast the future prospect.
ABSTRACT
[Objective]To observe the effect and the safety of the COX-2 inhibitor Celecoxib as the analgesia in orthopaedic post-operative patients.[Method]Sixty-four operative patients were selected in all between 2004～2005 in hospital,and divided into two groups randomly.Celecoxib was used as the postoperative analgesia in the experiment group and the "Patient-controlled analgesia" in the control group.The administration of Celecoxib: 8-12 hours before operation generally,just before the abrosia,and 6 hours after operation when patients can take food.drug withdrawal was depended on the complex of the operation and the severety of pain in 3 to 5 days.Dosage:400 mg first time,if a complicated operation,larger dose would be given.VAS score,adverse reaction and the satisfaction of patients were observed.[Result]The effect of Celecoxib is similar as the PCA,with less adverse reaction and more satisfaction.[Conclusion]Celecoxib has a satisfactory effect and safety as a postoperative analgesia,and is suitable to be a peri-operative analgesia of orthopaedic patients.
ABSTRACT
Twenty-four New Zealand rabbits were used in the experiment. Four animals served as control and the other 20 were fixed by stainless—steel plates on their left tibia to induce the local osteoporosis. The plates were removed 2 monthes after implantation. Four animals were killed immediately following the plate removal and the others were sacrificed 1, 2, 3 and 4 months later, respectively. The cortical bone beneath the plates were prepared for transmission electron microscopy observation. The results indicated that the recovery process of the local osteoprosis after the rigid plate removal mainly manifested the decrease in bone resorption and the increase in bone formation, which included osteoblastic and osteocytic.
