2.Correlation between allergy and HLA genetic polymorphism
Chinese Pharmacological Bulletin 1986;0(04):-
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.
3.Positron emission tomography and microvascular research
International Journal of Biomedical Engineering 2006;0(02):-
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.

Chinese Pharmacological Bulletin 1986;0(06):-
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
5.Changes in circulating endothelial cell numbers and blood lipid levels and their clinical significance in patients with multiple organ dysfunction syndrome
Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2006;0(03):-
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
6.Current situation of hypopharyngeal cancer radiotherapy
Journal of International Oncology 2014;41(4):264-267
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.
7.Non-linear developable model of skeletal muscle
Chinese Journal of Rehabilitation Theory and Practice 2004;10(7):442-444
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.

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.

Objective To investigate the potential mechanisms of vascular dementia (VD) by comparing the neuroethological and pathological changes of two VD models, established with spontaneously hypertensive rat (SHR) and the rat, of which the bilateral carotid arteries were ligated. Methods Ten male SHRs were employed and defined as hypertension control group. Thirty male Wistar rats were randomly assigned to operation group (bilateral carotid arteries were ligated), sham group and control group. All rats enrolled in the operation group were undergone a permanent ligation of bilateral carotid artery (2-VO). The memory function of rats was estimated by the mean escape latency of Morris water maze. The morphological changes of neuron cells in the frontal lobe, temporal lobes, hippocampus and thalami were observed with HE staining, while the changes of white matter around cerebral ventricles were checked with LFB staining, and the demyelination of nerve was calculated. Results The memory function of rats in SHR control group and Wistar operation group was decreased compared with that of the rats in sham group and control group (P0.05). Conclusions SHRs without intervention and Wistar rats undergone 2-VO can be used to reproduce the ideal VD model. Both chronic permanent hypoperfusion and hypertension may lead to the loss of neurons and myelin which may result in memory dysfunction. Hypoperfusion is even more harmful than hypertension. The present study suggests that loss of neurons and myelin may play a role in the VD.
