Hypopharyngeal cancer is not common and its prognosis is among the worst in head and neck cancer.Radiation therapy is an important choice of treatment,including radiotherapy alone,radiotherapy combined with surgery and radiotherapy combined with chemotherapy.The improvement of radiation therapy improves the prognosis of hypopharyngeal cancer patients,and radiotherapy combined with surgery is the standard treatment for hypopharyngeal cancer.Nowadays,in order to enhance the preserving rates of the organ and faction,radiotherapy combined with chemotherapy is becoming a research hotspot.

Positron emission tomography(PET) plays an important role in the research of substance distribution in Human body. The distribution of substance in whole body is carried out by the transport via circulation system and exchange between blood and tissue which occurs in microvascular. Both the research of PET and of microvascular are focused on the transport and exchange of substance in human body. So it should be meaningful to apply PET image to the research of microvascular, and to use the microvascular theory to improve on the analysis of PET image. In this article, some research in this domain are introduced, and foreground is reviewed.

Allergy increasingly threatens human health. At present, the molecular mechanisms of allergy have been one of the hot topics. It is believed that genetic factor and environmental factor play important roles in allergy. It is not surprising that particular HLA (human leukocyte antigen) class II alleles have been implicated in susceptility to allergic diseases and in restriction of the IgE responses to a variety of allergens. It will provide an original measure if the correlation between allergy and HLA genetic polymorphism was illuminated.

Objective: To investigate the relationship between circulating endothelial cell(CEC)(numbers),blood lipid levels and multiple organ dysfunction syndrome(MODS) and their clinical(significance).Methods: CECs were separated by isopyknic centrifugation method and blood lipid was(determined) in(35 MODS) patients and 20 healthy controls.CEC numbers and blood lipid were compared in both groups.(Acute) physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score was recorded to evaluate the severity of the MODS patients.The relationships were analyzed between APACHEⅡ score and CEC numbers,(between) APACHEⅡ and blood lipid levels and between CEC numbers and blood lipid levels.Results: CEC numbers in MODS patients were significantly higher than those in healthy controls(P

The paper explains factors that restricting the development of the mobile healthcare information system in small and medi -um hospitals , summarizes strategies for constructing the mobile healthcare information system in small and medium hospitals , and analy-zes advantages of the Android system as the development platform of the healthcare information system .On the basis of above , it designs a model suitable for the mobile healthcare information system in small and medium hospitals and introduces the system in details including the design principles , structure and service modes for clients , etc.

Aim To explore the correlation of positive specific IgE antibodies with penicillin allergy and HLA-DRB genetic polymorphism.Methods Sequence specific primer-polymerase chain reaction(PCR-SSP) was used to type human leucocyte antigen-DBR(HLA-DRB) alleles in 80 patients with positive IgE antibodies to penicillin and 101 healthy subjects without any allergic reactions.Results When different penicillin antigens were analyzed separately,the gene frequencies of DR16 in patients with positive BPO-IgE antibody and DR14.1 in patients with positive PVO-IgE antibody were found greatly lower than those of the control subjects(0 vs 8.62%,P

Objective To discussing the methods used in creating non linear developable biomechanical models of skeletal muscle.Methods One of the basic tools of the analytical approach in analytical mechanics, the principle of virtual work for deformable systems, was used to create the model. By means of method of Lagrange multipliers, the problems of constraints, such as the incompressibility of skeletal muscle, were effectively tackled. Results and Conclusion The biomechanical models of skeletal muscle has been developed. The program of this model can be used to obtain nodal displacement coordinates of given nodal coordinates and parameters.

AIM: To access the difference of the efficacy between terbinafine and itraconazole in the treatment of dermatophyte onychomycosis. METHODS: The Medline, Science Direct On Site (SDOS), and Springer database were searched in detail on the data of the mycological cure rates of the two antifungal agents for treatment of dermaphyte onychomycosis occourring in patients aged from 18 a to 60 a with the published double blind randomized clinical trials and then pooled. The odds ratio (OR) and its 95 % confidence interval (CI) were calculated. RESULTS: Six treatises of double blind randomized clinical trials were selected for this analysis according to the screening criteria. The mycological cure rate of continuous terbinafine 250 mg per day was higher than that of either therapeutic effect of itraconazole pulse 400 mg per day (OR = 5.01, 95 % CI (3.42 - 7.33)) or continuous itraconazole 200 mg per day (OR = 2.58, 95 % CI (1.91 - 3.49)) . CONCLUSION: Terbinafine is more effective than itraconazole in the treatment of dermatophyte onychomycosis.

Radiotherapy is an importment local treatment for non-small cell tung cancer. In recent years,with the development of molecular biology and radiotherapy technique and the update of equipment,radiation pattern with different doses segmentation and the concept of the combined therapy including radiotherapy and chemotherapy have been applied in clinic gradually,which get better effects.

Aiming at the issue of motor imagery electroencephalography (EEG) pattern recognition in the research of brain-computer interface (BCI), a power feature method based on discrete wavelet packet decomposition is proposed for the channels C3 and C4. Firstly, a six-border Butterworth filter is used to denoise the two-channel EEG signals. Secondly, two-channel EEG signals are decomposed to five levels using Daubechies wavelet and the fourth level and the fifth level are chosen to reconstruct the signals and compute its power feature. Finally, linear discriminant analysis (LDA) is utilized to classify the feature and the Kappa value is utilized to measure the accuracy of the classifier. This method is applied to the standard dataset BCICIV_2b-gdf of BCI Competition 2008, and experimental results show that this method reflect the feature of event-related synchronization and event-related desynchronization obviously and it is an effective way to classify the EEG patterns in the research of BCI.
