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.

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 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.

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 compare the differences of lifestyle factors between patients with functional constipation (FC)and constipation-predominant irritable bowel syndrome (IBS-C).Methods From February 2011 to December 2014,255 patients with chronic constipation were enrolled.Among them,there were 170 FC patients and 85 IBS-C patients.At the same period,170 healthy volunteers without symptoms of digestive diseases within one year were recruited as control.The data of demographic information and lifestyle factors were collected.First,single variant analysis was performed for statistical analysis and then the statistically significant variants were analyzed by multivariate logistic regression. Then the factors of FC and IBS-C patients were analyzed by decision tree model and the effects of factors under different categories were analyzed.Results The results of single variant analysis indicated that there was no difference in lifestyle factors between FC group and IBS-C group (all P >0.05).The results of multivariate logistic regression analysis showed that no independent protective or risk factors were found in IBS-C group compared with FC group.According to decision tree model analysis,body mass index (BMI),water intake per day and constipation family history were finally enrolled.The incidence of FC was higher in patients with BMI < 23.56 kg/m2 (except 18.74 to < 19.83 kg/m2 )(79.75 %).The incidence of FC was higher in patients with BMI from 18.74 to <19.83 kg/m2 and water intake <1 L
(66.67%).The incidence of FC was highest in patients with BMI≥23.56 kg/m2 and family history of constipation (70.00%).The total prediction accuracy of this model was 64.6% (42/65 )and area under curve (AUC)value was 0.688.Conclusions FC and IBS-C are related with many lifestyle factors.Low BMI and less water intake per day are influence factors of FC,while higher BMI and family history of constipation are influence factors of IBS-C.
