OBJECTIVE To understand the current situation in management of nosocomial infections in hospitals,and provide rational preventive measures in order to improve the medical care quality.METHODS An observatory study was conducted and reasonable suggestions were preferred referring to foreign nosocomial infections modes.RESULTS Problems were found to a different extent in administration of nosocomial infections.Most alarming problems were shortages of rules and regulations,and deficiency of infection propaganda and administration coordination.CONCLUSIONS Strengthening management of nosocomial infections is one of the key issues for improvement of the medical care quality and should be paid special attention.

Objective To study the CT manifestations of thyroiditis. Methods CT findings on plain and contrast enhanced thin-slice CT scan of 36 cases with thyroiditis proved by surgery (34/36) or fine needle biopsy (2/36) were analyzed retrospectively.Results There were 28 cases of Hashimotos’ thyroiditis.The characteristic signs were seen in 68% cases (19/28).Plain CT scan showed diffuse and symmetrical enlargement of bilateral leaves and isthmus whith greately reduced density which was homgeneous or slightly heterogeneous,no calcification or lower density nodule was seen,conrast-enhanced CT scan demonstrated uniform enhancement which was more dense than adjacent muscles, the thyroid outline could be clearly defined and no lymphadenopathy was found. Symmetrical enlargement of bilateral leaves and isthmus with uneven density and multiple hyperdens nodules were presented in 1 case. 5 cases of Hashimotos’ thyroiditis associated with multinodular goiters revealed asymmetrical thyroid enlargement and uneven density on plain and conrast enhanced CT images. In 3 cases the thyroid gland was normal in size and shape,except for the reduced ,uneven density. Of these 3 cases,1 showed the enlargement of left lobe with a calcified nodule. There were 8 cases of subacute thyroiditis,the thyroids were asymmetrical enlargement ,strongly decreased in density with obscure margin and slight to intermediate enhancement.Conclusion CT is a very important modality for the diagnosis and differential diagnosis of various thyroidities.

Primary Hepatic Carcinoma(PHC)is one of the most common malignant tumors in the world.Nowadays,its incidence and mortality have been still increasing.With regard to the early treatment for PHC,the combined therapy,primarily referred to operation,is considered optimal.For recent decades,with the quick development of ultrasonic therapeutics,High Intensity Focused Ultrasound(HIFU)techniques,which rose newly,has already become a kind of effective and noninvasive substitution therapy for PHC operation therapy as a kind of noninvasive tumor therapy.Now,this literature review aims to summarize the found re- search and clinical research of HIFU therapy for primary hepatic carcinoma.
