Objective To compare the quality of Flos Farfarae from different habitats, and provide basis for the utilization and development of Tussilago farfara. Methods The contents of rutin and tussilagone were determinated by HPLC, the 100-bud dry weight and bud color were weighed and observed. And the data of different samples were compared and statistical analysed. Results The content of rutin, tussilagone and 100-bud dry weight in Flos Farfarae from different place has a significant difference, and there was a significant positive correlation between rutin and tussilagone. Principal component and factor analysis showed that the quality of Flos Farfarae from Yushe, Ningwu, Guangling was better than other areas. Conclusion The quality of Flos Farfarae from different areas is difference, and wild T. farfara in Yushe, Ningwu, Guangling could be used as high quality germplasm.

ObjectiveTo evaluate the safety,therapeutic effect and complications of the operation of multi-section osteotomy and intramedullary fixation for children with osteogenesis impeffecta.Methods One hundred and twenty-three children with osteogenesis imperfecta,including 85 males and 39 females,were selected from August 2005 to August 2008.According to the modified Sillence classification,45 cases was in type Ⅲ,74 in type Ⅳ,and 5 in type Ⅴ.Patients' age was ranging from 2 years and 1 month to 15 years and 7 months (mean,8 years and 3 months).The location of osteotomy was established according to the pre-operative measurement of X-ray image,and all the procedures of osteotomy were completed under direct vision.Then we chose the intramedullary pin with suitable size and insert the pin into femur from greater trochanter,and tibia from pelma.After the surgery,external fixation (spica cast for the femur,long leg plaster cast for the tibia) was made for further stabilization.Plaster supporters were removed 6 weeks later and all children began to stand and walk under the protection of orthoses.In addition,all patients received the treatment of pamidronate disodium periodically.ResultsAll 123 children were followed up for an average of 38months (range,13-64 months).Parents of all children were satisfied with the result of surgical operation,and the children's self-care and motion ability improved obviously.Fourteen children were performed the second operation due to the translocation of Rush pin,and 25 children changed the internal fixation because of the shorter Rush pin 2 years postoperatively.Bone delayed union was not found in all patients.Conclusion Multi-section osteotomy and intramedullary fixation for children with osteogenesis imperfecta could correct skeletal deformity,improve motion ability and avoid second fracture efficiently.However,such complications as translocation of intramedullary pin and changing the internal fixation with the growth of child need to pay more attention.

Objective To explore the application of video laryngoscope in patients with pituitary adenoma during endotracheal intubation.Methods Fifty-one patients (19 males, 32 females, aged 18-71 years, ASA physical status I or II) scheduled for resection of pituitary adenoma under general anesthesia were enrolled.These patients were randomly divided into two groups: Macintosh laryngoscope Group (group M, n=25) and Video laryngoscope Group (group VL, n=26).When performing endotracheal intubation, Macintosh laryngoscope was used to expose the glottis in group M, and video laryngoscope was used in group VL.Head tilted backward angle, mouth opening, thyromental distance, neck circumference, mandibular ramus length, modified Mallampati classification and the difficulty classification of mask ventilation of the patients in two groups were recorded during peri-operation period.The Cormark-Lehane grade, needed pressing of the cricoids cartilage, the ratio of a second attempt during intubation and the intubation time consumed were recorded.Results Less patients in group VL needed cricoids cartilage press (7.7% vs 48.0%) during the intubation than that in group M (P<0.01).Compared with group M, the Cormack-Lehane grade was significantly lower (P<0.01) and the intubation time consumed was significantly shorter in group VL [(32.4±11.7)s vs (45.8±12.6)s] (P<0.01).Conclusion In patients with pituitary adenoma,video laryngoscope may improve the glottis exposure and the success rate of intubation, as well as shorten the intubation time.

Objective To report the outcome of emergency repair traumatized limbs by vascularized free tissue transplantation.Methods From April 1988 to August 2004,86 patients,58 men and 28 women,had undergone emergency vascularized free tissue transplantation to have their injured limbs repaired in 54 cases and the missing thumbs reconstructed in 32.The patients aged from 5 to 55 (mean 27.9) years. The transplants included latissimus dorsi myocutaneons flap,anterolateral femoral skin flap,medial crural skin flaps,dorsal pedal flaps,medial plantar flap,composite tissue mass of the discarded limbs and big toe skin- nail flap.The operations were performed 1 to 5 days after injuries.Results Postoperative vascular crises occurred in 8 cases and were all followed by exploration with successes in 5 cases while failure in 3.The total survival rate of the transplants was 96.5% (83/86).In this series all the patients were followed up for 1 to 16 years with a mean of 7.5 years only to reveal satisfying functional recovery in all the repaired limbs and an ex- cellent and good rate of 87.5% in the reconstructed thumbs.Conclusion Emergency vascularized free tis- sue transplantation is an effective way to repair a traumatized limb and to reconstruct a traumatically missing thumb.
