Bicuspid aortic valve (BAV) is one of the most common congenital valvular diseases, which is often associated with aortic stenosis or insufficiency.Aortic disease is an important component of BAV, aortic root aneurysm is the most finding when it comes to the dilatation of any or all segments of the proximal aorta from the aortic root to the aortic arch.The choice of operation has a great influence on the prognosis of patients.This article discusses the anatomic basis, pathophysiology, surgical treatment and treatment effects of the bicuspid aortic valve with aortic root aneurysm.

WGA-HRP was injected into the inferior colliculus in the rat in order to study the non-auditorial afferents of the inferior colliculus. In the diencephalon and truncus encephali, retrograde labeling was observed in many non-auditorial regions: bilateral (with contralateral predominance) cuneate nucleus, gracile nucleus, nucleus of spinal tract of trigeminal nerve, nucleus medullae oblongatae centralis dorsalis; bilateral (with homolateral predominance) locus ceruleus, nucleus reticularis pontis oralis, laterodorsal tegmental nucleus, substantia nigra, sub-parafascicular nucleus, perifornical nucleus; bilateral medial parabrachial nucleus, deep tegmental nucleus of midbrain, lateral hypothalamic area; homolateral deep layer of superior colliculus, zona incerta; contralateral nucleus of solitary tract; and posteromedian septum, central tegmental nucleus, dorsal nucleus of the raphe. The afferent neurons from cuneate nucleus, gracile nucleus, nucleus of spinal tract of trigeminal nerve, nucleus of solitary tract mainly located below the level of obex. The results mentioned above suggested that the inferior colliculus is not only an auditorial relay nucleus, but also a complex body which is of different functions.

Objective To compare and determine the reproducibility of apparent diffusion coefficient (ADC)values of the normal liver parenchyma in respiratory-triggered,breath-hold,and free-breathing diffusion weighted magnetic resonance imaging (DWI). Methods 11 volunteers did three times of breath-hold (excitation number is 1,at the end of the expiration,thickness/gapping=5 mm/1 mm), respiratory-triggered (excitation number is 2,at the end of the expiration,thickness/gapping=5 mm/1 mm),free-breathing (excitation number is 4,thickness/gapping=5 mm/1 mm)and for a total of nine axial liver DWI,the gradient factor was 800 s/mm2 .Then they were all coronally reconstructed (thickness/gapping=8 mm/1 mm).The nonparametric test was used to compare all axial and coronally reconstructed liver ADC values;and the Bland-Altman method was used to evaluate the ADC values’repeatability in coronally reconstructed images.Results The breath-hold DWI’s mean ADC value was (1.09±0.07)×10-3 mm2/s significantly lower than the respiratory-triggered DWI(1.16± 0.09)×10-3 mm2/s and the free-breathing DWI(1.19±0.10)×10-3 mm2/s(P<0.005),the axial and coronal images’results were similar.The ADC values’average difference and scope of consistency of coronal image were (-0.09 to -0.01±0.09 to 0.48)for breath-hold DWI,(-0.04 to 0.01±0.11 to 0.17)for respiratory-triggered DWI,(-0.07 to -0.02±0.11 to 0.18)for free-breathing DWI,respectively.Conclusion The breath-hold DWI’s ADC value of normal liver parenchyma is lower than the respiratory-triggered and free-breathing DWI,and showed more poorer repeatability.It is suggested that the measurement of ADC values of the liver parenchyma should be done within the respiratory-triggered or free-breathing DWI.

By theory analysis,a good method named 2D multi-resolution Wavelet analysis is obtained.This method can effectively eliminate noises and swell signals.Consequently,the reconstruction of PET image is accelerated and the quality of PET image is improved.

A registration method for 3D abdominal ultrasonic images without added hardware is proposed,whose key is to determine the relative position of the target from the registration substance.The registration involves such steps as registration plane scanning,establishment of registration table,section plane scanning,recognition of registration substance and registration of all sections.

Objective To analyze the clinical efficacy of recombinant human granulocyte macrophage colony stimulating factor gel in the treatment of burn wounds.Methods 80 cases of burn patients in our hospital from February 2016 to February 2017 received treatment, were randomly divided into control group and observation group, 40 cases in each group, the control group given routine treatment, and the observation group was treated with recombinant human granulocyte macrophage colony stimulating factor gel on the basis of the treatment of the control group.The clinical effects of the two groups were compared and analyzed, including the healing time, the total effective rate of wound healing, the healing rate of the wound, and the related adverse reactions.Results The patients in, the healing time, total wound healing efficiency,and wound healing rate of the control group were significantly better than those of the control group(P<0.05), and no adverse reactions occurred in the two groups.Conclusion Burns were treated with recombinant human granulocyte macrophage colony stimulating factor gel treatment can effectively improve the treatment of patients with total efficiency, shorten the healing time, and can improve the healing rate, the treatment has a very important meaning and value, worthy of promotion and application in clinical widely.

Synovial sarcoma(SS) is a common soft tissue tumor,which origin hasn’t been confirmed. With different morphology and various differentiation, SS is likely to be confused with other soft tissue tumors.Therefore,the rate of misdiagnosis is very high.It is very diffi cult to diagnose SS just relying on symptom,sign,imaging and so on. The article mainly reviews the advances on immunohistochemistry and genetical detection in diagnosis of SS.

Sentinel lymph node(SLN) is prevalently studied in breast cancer and malignant melanoma as well as being applied in clinical practice.Currently,the study on sentinel lymph node of gastric cancer has gradually been a vital component in the study of diagnosis and treatment of gastric cancer.Sentinel lymph node examination is feasibly applied in clinical T1N0M0 stage gastric cancer or early gastric cancer because of its high accuracy and sensibility.However,the sentinel lymph node examination is not suitable for advanced gastric cancer due to low sensibility and high false negative rate.The article mainly reviewed the advances on SLN tracer,application,micrometastasis,imaging system and so on in gastric cancer.

Objective To conduct lossless compression to medical images with lossless regions of interest.Methods Firstly,the shape information of interest regions were segmented and pick up.Then,the self-adaptive wavelet transform was performed to transform interest regions.At last,the modulus of the interest regions and the rest were coded respectively before being stored or transmitted.Results A method for medical image compression based on shape-self-adapted ROI was raised.Conclusion The whole image can be highly compressed with high fidelity
