Objective To evaluate CT features and diagnostic value of fungus infection of paranasal sinuses. Methods CT findings in 16 patients with fungus infection of paranasal sinuses proved surgically and pathologically were analyzed.Results CT findings of fungus infection of paranasal sinuses included: unilateral involved, maxillary sinus was mainly affected or other paranasal sinuses involved simaltaneously, the soft tissue within paranasal sinuses presented as hyperplasia of nodule and polyp-like, and there were some punctuated and tubercular calcification inside .Sinus cavity enlarged and the bone wall was destroyed in some cases. Conclusion CT manifestations of fungus infection of paranasal sinuses are of characteristics, CT scan is of important value in diagnosing this disease.

0.05)significant difference in 30 days (P0.001) between trunks groups and branches groups.Conclusion For the pationts with hypersplenism arteries were two or three branches,the PSE operation in the splenic arteriosus branches should be done,if splenic arteries were no truncus or truncus obvious crooked causing to introduce the catheter difficuty,the PSE operation in the splenic arteriosus truncus should be done.

OBJECTIVE: By studying the MRI apperances of postcricoid area invaded by laryngeal carcinoma, to identify the characteristic appearances of the invaded postcricoid area and to provide information on the early detection of the lesions. METHOD: Eighteen cases of MRI images of postcricoid area invaded by laryngeal carcinoma were included in this study. To find out the characteristic manifestation of the lesions, the destructions of surrounding structures and layers, and the invaded extent were observed. RESULT: In 18 cases the invaded lesions of postcricoid area include the mucous layer, submucous fat layer and the mucous layer of anterior wall. In 14 cases the invaded lesions of postcricoid area include the mucous layer, submucous fat layer and the mucous layer of the posterior wall. The soft tissue mass was found in 15 cases, and disappeared hypopharynx cavity in 16 cases. In 14 cases, the full-thickness of both anterior and posterior walls were invaded, accompanied with soft tissue mass and disappeared hypopharynx cavity. CONCLUSION The postcricoid area invaded by laryngeal carcinoma usually shows the destruction of normal structures, signal change in MRI and soft tissue mass. Being familiar with the imaging of the invaded postcricoid area is extremely important to early detect laryngeal carcinomas invading postcricoid area.

Carpal tunnel syndrome(CTS)is one of the most common peripheral nerve entrapment disorders,the elevated pressure in the carpal tunnel,high-intensity activities and obesity are the main causes,and the patients with mild to moderate CTS are more prevalent.The main pathogenesis of CTS involves the increasing of carpal tunnel pressure and impaired local blood oxygen supply leading to reduced nerve conduction.Currently,the clinical treatment methods for mild to moderate CTS mainly include surgical and nonsurgical treatments.Nonsurgical treatment is the preferable choice for the patients with mild to moderate CTS.The western medical treatment primarily rely on oral medications,but their long-term use is limited due to the certain adverse effects;the local blockade and extracorporeal shock wave therapies show better efficacy for the patients with frequent activities and severe symptoms;the traditional Chinese medicine treatment also becomes a choice for some CTS patients due to their advantages of less pain,lower medical costs,and significant effectiveness.This study reviews the recent advancements in the pathogenesis and treatment of mild to moderate CTS,in order to design the personalized treatment methods for the mild to moderate CTS patients based on their specific conditions in clinical settings and provide the references for precise treatment of the mild to moderate CTS patients.
