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.

Objective To investigate the short-term and long-term effect of cornary-caval shunt accompanied by pericardial devascularization in the treatment of upper gastrointestinal bleeding caused by portal hypertension.Methods Eleven patients with portal hypertension underwent cornary-caval shunt accompanied by partial pericardial devascularization were chosen.Of the 11 patients 6 applied autogenous splenic veins for graft and in 5 cases the coronary vein and inferior vena cava were anastomosed directly.Results Of the 11 patients,no operative mortality or early rebleeding.All patients were followed up from 5 months to 11 years with an average of 5 years and 3 months,of whom two died,others having no rebleeding or hepatic encephalopathy.Conclusion Cornary-caval shunt is a highly selective portosystemic shunt.Cornary-caval shunt accompanied by pericardial devascularization is a surgical treatment of upper gastrointestinal bleeding caused by portal hypertension for its apparent regional antihypertensive effect,the normal blood flow of liver,and reduction of the incidence of rebleeding.
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 identify the role of RNA-editing enzyme ADAR1 (adenosine deaminase acting on RNA) in EV71 infection and virus mutation.Methods RNAi technology was applied to establish ADAR1 knock-down stable cell lines.Then the cells were served to evaluate the role of ADAR1 in EV71 infection by MTT assay for detecting virus-induced cell viability,virus plaque assay for quantification of the virus titer and the cellular susceptibility to the virus,and Western blot for virus protein expressions.ADAR1-mediated RNA editing can result in the genetic A-G and T-C mutations.To further determine whether the effects of ADAR1 on EV71 infection were correlated with ADAR1-mediated EV71 RNA editing and therefore increased the viral mutations during the infection,the characteristics of EV71 mutation were analyzed based on the different full-length viral genomes from epidemic regions.The viral genome was also sequenced from the infected ADAR1 knock-down cells.Results After ADAR1 knock-down,the cell viability decreased quickly after the virus infection,and formed much more and larger sizes of plaques than the control cells.The virus capsid protein VP1 expressions and virus titer in the cells culture media were both increased in ADAR1 knockdown cells.Statistic analysis showed that A-G and T-C mutations were the major mutations of EV71,which were believed to be the hot sites for RNA-editing.However,the results of viral RNA genomic sequencing data indicated that ADAR1 did not edit EV71 genome directly.Conclusions ADAR1 was a restriction factor for controlling EV71.However,ADAR1 does not directly edit EV71 genome.

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.

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.
