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.

With GC-MS、LC-UV and gene analysis,we studied Pseudonomas sp.W2 metabolic pathway of bisphenol A(Bpa).It was discovered that 4'-(trimethylsiloxy)-Acetophenone、p-Hydroxy benzaldehyde and p-Hydroxy benzoic acid are medium metabolites and that the bacteria has pcaG.

Objective:To establish a tongue cancer cell line that stably overexpresses nm23-H1.Methods:The reconstructed plasmid, pCMV-BamH1-Neo-nm23-H1, was transfected into bacteria and amplified. The plasmid was identified by electrophoresis on a 10 g/L agarose gel and stained with ethidium bromide and then transfected to the cell line of Tca8113 by lipofectin strategy and was selected by G418 for 5 weeks. The stable expression of nm23-H1 was identified by immunofluorescence,Western-blotting and flow cytometer.Results:Restriction endonuclease Bam H1 examination showed that 986 bp of nm23-H1 was in pCMV-Bam-Neo vector. 5 weeks after transfection positive clones were obtained and the transfected cells were proliferated to confluent.Immunohistochemical examination,Western blot and flow cytometry showed that nm23-H1 expression was increased in the transfected cells.Conclusion:A tongue cancer cell line expressing nm23-H1 is established.

Objective To explore the anatomy and the adjacent of the medial malleolus,the operative approach of soluting the tibial nerve in endoscopy and the significance of making use of it in operation. Methods The five cadaver feet were dissected,the tibial nerve and the fiber diaphragm in the middle of me- dial and lateral plantar tunnels in the ten cadaver feet were soluted in endoscopic.Results The operative approach was designed on the basis of the anatomy data (the three-portal approach:The perpendicular bisetor which was the medial malleolus pointed to the medial margin of tendon calcaneus insertion was 4.5cm;The midpoint of the medial malleolus pointed to the calcaneus tubercle;The midpoint of the calcaneus tubercle to the medial margin of the first metatarsophalangeal joint).It was succeed that soluted the tibial nerve and the fiber diaphragm in the middle of medial and lateral plantar tunnels.Conclusion The operative approach on the basis of the anatomy data is design,and testfy the feasibility of exploring curved tunnel in endoscopic.
