OBJECTIVE To investigate the distribution of infectious diseases and diagnostic and therapeutic conditions in pediatric department of a general hospital,and try to find out the measures to decrease hospital infection.METHODS From Jan 2004 to Dec 2005,507 cases of infectious diseases were retrospectively analyzed in pediatric department of our hospital.RESULTS Among them epidemic parotitis,infectious diarrhea and bacillary dysentery were 56.2%,20.1%,and 17.4%,respectively.Others were measles,scarlet fever,rebella,viral hepatitis,epidemic cerebrospinal meningitis,typhoid,and syphilis.Among the cases,the most were outpatients.CONCLUSIONS Because the species of infectious diseases are various and the amount are large,the pediatric department is important in a general hospital for management of hospital infection.Strengthening the standardized management of pediatric infectious diseases and taking strong measures may play the important role in control the cross infection.

HLA (human leukocyte antigen) is critical molecule relevant to immunoresponse, which is always involved in antigen presentation and determining killing activity of immune cells against tumor. The abnormal expression of HLA in lung cancer is believed to be a common phenomena of tumor biology. It has been demonstrated that HLA expression varies in various types of lung cancer, even in differential stages of one type of lung cancer. HLA expression is highly associated with genre, progression and prognosis of lung cancer. The thorough investigations of the relationship between HLA and lung cancer and of mechanism of HLA abnormality will provide useful information for studying of development of lung cancer and tumor immunotherapy.

How to acquire new tumor antigens is a hotspot in cancer research currently.According to the nature of antigen epitope binding its ligand,we can identify and get unknown antigen epitope even its amino acid sequence through some analytical techniques and experiments,from T lymphocytes and monoclonal antibody levels.So the molecular mechanisms of tumor immunity will be more distinct.

Objective To evaluate the effects of 0.3 kb human alpha-fetoprotein (AFP) promotor on the expression of enhanced green fluorescent protein (EGFP) in human hepatoma cells. Methods By constructing the primer with special enzyme site, human AFP promoter was selectively amplified from human gene bank and eukaryon-expressed pAF-EGFP and pAF-DTA with AFP promotor and EGFP and with AFP promotor and DTA, respectively. pAF-EGFP was transfected into HepG2, SMMC-7721, and NIH3T3. The fluorescence was detected in order to evaluate the transfection rate. Results The expression of EGFP in HepG2 cells transfected with pAF-EGFP was significantly higher than that in SMMC-7721 and NIH3T3 cells (P

Objective To investigate the diagnostic points of multiple sclerosis and multiple metastatic encephaloma.Methods Choose a case of multiple sclerosis,which had been misdiagnosed as multiple metastatic encephaloma and operated on,to analyse its reasons of misdiagnosis.Results Reasons for the misdiagnosis:The neglect of the importance of the disease history.The scant knowledge of the early represen- tations of the atypical MS(demyelinating pseudotumor).The lack of the knowledge of the non-demyelinating lesions of the MS.The lack of attention to the different representations of the MRI scan between the acute MS and the multiple metastatic encephaloma.The excessive importance is attached to the imageological report. The neglect of the routine examination of cerebrospinal fluid.Conclusion When multiple metastatic en- cephaloma develops,the differential diagnosis of MS should be made.The further examinations should be done to those cases which are hard to tell the difference with metastatic encephaloma by clinical and imageo- logical representations.Try to avoid undergoing surgery or radiotherapy hastily.

Objective:To observe effects of Tongmai Yizhi Capsules on trace elements in the patient of vascular dementia.Methods:Blood trace elements Cu,Se,Zn and Fe contents before and after treatment were investigated in a Tongmai Yizhi Capsules group(n= 50)and a Hydergine group(n=30).Results:After treatment Cu,Se contents increased and Zn and Fe contents decreased in Tongmai Yizhi Capsules group with significant difference as compared with Hydergine group(P

Objective To investigate the diagnostic value of 18F-fluorodeoxyglucose (FDG) PET/CT in the localization of ectopic adrenocorticotrophic hormone ( ACTH)-secreting tumors. Methods Seven patients with ectopic ACTH syndrome (confirmed by clinical symptom, biochemical data or bilateral simultaneous inferior petrosal sinus sampling) were included, 4 males and 3 females with age ranged 27-63 years old.All patients were examined with head MR, chest and abdomen CT, abdomen ultrasonography, and whole body 18F-FDG PET/CT. Location, size, and the maximum standardized uptake value (SUVmax) of the tumor were measured. Results 18 F-FDG PET/CT detected three ectopic ACTH-secreting tumors with the sizes 1. 1 cm×1.0 cm (SUVmax =9.4), 1.5 cm×1.1cm (SUVmax =6.4), and 1.6 cm ×1.5 cm (SUVmax =12.0). The pathological findings of the three tumors were thymoma, lung carcinoid, and mediastinal carcinoid respectively. Conclusion 18 F-FDG PET/CT may help the localization of ecto pic ACTH-secreting tumors .

With the rapid progress of rehabilitation in China, how to construct the accreditation system of physical therapy (PT) education has become a critical consideration. This article introduced the background, role, management and process about the accreditation system of PT education in United States in order to promote the development of PT education in China.
