Effect of Different Drying Methods on Physical Fingerprint and Total Flavonoids Content of Mori Ramulus Extract / 中国实验方剂学杂志

Objective: To investigate the influence of different drying methods on physical fingerprint and total flavonoids content of Mori Ramulus extract.Method: The Mori Ramulus extract was dried by freeze drying,vacuum drying,ambient pressure drying,respectively.The content of total flavonoids in samples with different drying methods were determined and compared with each other.Physical fingerprint of Mori Ramulus extract was established by radar map and the physical fingerprint of samples with different drying methods were compared with each other.In the meantime,compressible parameters were employed to analyze the compressibility characteristics of Mori Ramulus extract treated by different drying methods.Result: Similarity of control physical fingerprint of Mori Ramulus extract treated by different drying methods was 77.8%-87.3%,relative standard deviation(RSD) of average value of the first level indexes and the compressible parameters was 0-16.6%.Except for homogeneity and stability,the remaining RSDs were less than 10%.Effects of different drying methods on homogeneity and stability of Mori Ramulus extract were greater than that of other factors.Conclusion: Different drying methods have certain effects on physical fingerprint of Mori Ramulus extract,but they have little influence on total flavonoids content in Mori Ramulus extract.

Effecive observation of percutaneous reduction and Kirschner pin fixation for treatment of supracondylar fracture of humerus in children / 中国骨伤

<p><b>OBJECTIVE</b>To study on the clinic effect of percutaneous reduction and Kirschner's pins fixation for treatment of supracondylar fracture of humerus in children.</p><p><b>METHODS</b>From June 2001 to Nov. 2007, 26 patients of supracondylar fracture of humerus in children were reviewed. All patients were treated by the fixation of percutaneous reduction and Kirschner's pins under the C-arm X-ray machine. These patients were included 16 males and 10 females with the age from 3 to 10 years. There were 17 cases on the left and 9 cases on the right. There were 24 cases of extension type and 2 cases of flexing type and all the cases were considered as closed fracture without any injury on nerve and vascular. These patients were all under operation from half an hour to 7 days after being injured, and 15 of them were sent to the hospital and received operation immediately.</p><p><b>RESULTS</b>These 26 cases were followed-up for 3 to 9 months, all fractures of them were healing. According to the comprehensive evaluation, the result of 16 cases were excellent, 8 cases were good, and 2 cases were fine.</p><p><b>CONCLUSION</b>From the research, the method of percutaneous reduction and Kirschner's pins fixation for treatment of supracondylar fracture of humerus in children with the assistance from C-arm X-ray machine is safe, convenient, less injured, with reliable fixation, complication-minimizing, and easy for functional recover.</p>
