The quality of traditional Chinese medicines (TCMs) has been mainly evaluated based on chemical ingredients, yet recently more attentions have been paid on biological ingredients, especially for pill-based preparations. It is a key approach to establish a fast, accurate and systematic method of biological ingredient analysis for realization of modernization, industrialization and internationalization of TCMs. The biological ingredient analysis of TCM preparations could be abstracted as the identification of multiple species from a biological mixture. The metagenomic approach based on high-throughput-sequencing (HTS) and big-data-mining has been considered as one of the most effective methods for multiple species analysis of a biological mixture, which would also be helpful for the analysis of biological ingredients in TCMs. Simultaneous identification of diverse species, including the prescribed species, adulterants, toxic species, protected species and even the biological impurities introduced through production process, could be achieved by selecting appropriate DNA biomarkers, as well as applying large-scale sequence comparison and data mining. By this approach, it is prospective to offer an evaluation basis for the effectiveness, safety and legality of TCM preparations.

With the rapid development of intensity modulated radiation therapy (IMRT) technique,the accuracy of radiotherapy has improved,while the pretreatment dose verification has become more complex.Although the experimental measurements,a widely used way to perform dose verification,is accurate and effective,its time-consuming and labor-intensive is still a challenge for physicist.The independent dose verification method such as the depth dose-off axis ratios (OAR) empirical model,Clarkson integral model,convolution model and Monte Carlo model,could partially solve these problems effectively when the accuracy is ensured within a certain range.This approach could save physicists' time to conduct dose recalculation and plan check,and has become the hotspot in the world.This paper,therefore,mainly introduces the correction-based and the model-based independent dose verification methods,and briefly discusses the development of dose verification for IMRT plans.

5.Clinical Observation of the Acute Osteomyelitis in Children
The Journal of the Korean Orthopaedic Association 1978;13(3):353-957
The clincal experience of thirteen patients with proven acute osteomyelitis under twelve years of age treated by surgical exprolation such as immediate decompression followed by continuous suction-irrigation. Five patients of them who had short duration from the onset improved while three patients who had long duration from the onset had persisting inflammatory change of the bone in spite of the regimen. The causating organisms were mostly staphylococcus aureus in bacterial cultures. The combination of gentamycin, minocin and penclox were the antibiotics of choice. Early diagnosis and early operation is advocated to attain good results in the treatment of acute osteomyelitis in the children.

Objective To compare success rate of intubation and safety of two types of video laryngoscopes during anesthesia in uvulopalatopharyngoplasty surgery (UPPP) for obstructive sleep apnea syndrome (OSAS) patients. Methods UPPP surgery were operated to 60 patients between January and October of 2013 and those patients were randomly divided into McGrath MAC video laryngoscope group (M group), GlideScope video laryngoscope (G group), and SHUCMAN direct la-ryngoscopy (S group), with 20 patients per group. Mallampati classification scores, Cormack-Lehane grade, intubation suc-cess rate, pre-intubation vs post-intubation heart rate and blood pressure changes were recorded and compared. Results Mallampati classification scores were not significantly different between these three groups, and Cormack-Lehane grade be-tween M group and G group were also not statistically different. M and G group had distinct advantages in Cormack-Lehane grade, success rate in intubation, heart rate, blood pressure at completion of intubation (T3) and 1 minute after intubation (T4), and the differences are statistically significant (P < 0.05). Blood pressure changes were stabler in G group than M group. Conclusion The two video laryngoscopes used in anesthesia intubation during UPPP surgery can both effectively re-veal the structure of the throat, but also work with high success rate and safety. What’s more, in this study the McGrath MAC video laryngoscope was shown to be superior to GlideScope video laryngoscope.

Objective To observe the effects of the intervention of Didang Decoction at different times on changes of AMPK signaling pathway related factors in macrovascular endotheliocytes of diabetic rats; To discuss the mechanism of mitochondria energy metabolism regulating the AMPK signaling pathway for macrovascular endothelial defense function. Methods Injection of STZ into the caudal vein and administration of high fat diet wer used to generate diabetic rat model. All rats were randomly divided into the following 7 groups: control, model, metformin, simvastatin, early-, middle-, and late-stage Didang Decoction group. Western blot was used to detect the expressions of APMKα1 and PGC-1α in rat aortic endothelial cells. Changes in the intracellular AMP and ATP levels were detected by ELISA. Real time fluorescence quantitative PCR was used to detected mRNA expressions of Caspase-3, eNOS, and Bcl-2 in tissue of thoracic aorta. Results Compared with the model group, the expressions of AMPKα1 and PGC-1α in the early-stage and middle-stage Didang Decoction group and simvastatin group increased (P<0.05); the gene expressions of Bcl-2, and eNOS significantly increased in the early-stage Didang Decoction group and simvastatin group (P<0.05), while the expressions of Caspase-3 decreased significantly (P<0.05). The expression of ATP increased significantly and the expression of AMP decreased significantly in the early-stage Didang Decoction group and simvastatin group (P<0.05), and the best effects were shown in the early-stage Didang Decoction group. Conclusion Early intervention of Didang Decoction can enhance energy metabolism in the mitochondria of macrovascular endothelial cells by regulating the AMPK signaling pathway, and then plays a role in strengthening the defense function of macrovascular endothelial cells.

In the treatment of flexor tendon injury of the hand, re-rupture after primary tendon repair is one of complications which occurs occasionally and so impose burden on both the patient and the surgeon. Authors experienced twelve cases of re-rupture after primary flexor tendon repair of 274 patients from Mar. 1989 to Mar.1996. The incidence of re-rupture after primary flexor tendon repair was 4.4% in author's series. One case happened with slip down injury, and in six cases re-rupture occurred during physical therapy with snapping click sound. However in five cases, the patients conldnt recognize any related causes. In majority of cases, re-ruptures were identified between three and five weeks after primary repair by the surgeon and the patient, so it could be suggested that the attention should be paid for the high possiblity of re-rupture during this period. Operative findings were the resorption and friability of repaired end with insecure suture fixation in two cases, rupture of suture material in four cases and loosening of the knot in six cases. From this study, the authors suggest the importance of knot, and recommend to make more than four knots on suture tie with attention to the tie direction, and advise careful physical therapy according to each patients' different situation. In the treatment of re-rupture, end-to-end re-anastomosis was available in seven cases (59%). In five cases (41%), tendon graft was needed. The clinical result of the re-rupture cases was evaluated by the Stickland evaluation method, and it was satisfactory in 67% of the patients who had the complication of re-rupture.
