This study was purposed to prepare eukaryotic expression vector of recombinant human platelet CD36 gene. The total RNA was extracted from human liver tissue and the cDNA encoding human platelet CD36 antigen extracellular region (Gly30-Asn439) was amplified by RT-PCR. The cDNA was cloned into the prokaryotic expression vector pMD18 and the recombinant vector was transformed into E. coli DH5α. The positive recombinant pMD18-CD36 plasmid was screened. After sequencing, this combinant vector was inserted into the transient eukaryotic expression vector pTE2, the pTE2-s-CD36-10 His transient eukaryotic expression vector was constructed. The recombinant CD36 Gly30-Asn439 expressed by HEK-293 cells was purified with Ni(2+) 2NTA chromatography. The results showed that 1.4 kb cDNA was amplified by RT-PCR, sequencing of the cDNA indicated the sequence was exactly the same to that in Genbank NM_001001547.2. The HEK293 cells with the plasmid were transfected, and SDS-PAGE confirmed that the transfect HEK293 cells expressed the human CD36 antigen extracellular protein fragments. Western-blot showed that the monoclonal antibody could recognize the recombinant CD36 with the sensitivity of 8 ng. It is concluded that the CD36 Gly30-Asn439 can be highly expressed by human embryonic kidney cells (HEK293), and the monoclonal antibody with biological activity has been obtained, which provide the basis for further study on platelet transfusion refractoriness.

Patients who underwent laparotomy often experience recurrent pelvic pseudocysts and they may need to undergo another laparotomy. Nowadays, many less invasive techniques such as the use of ultrasound-guided aspiration of pelvic pseudocysts and sclerotherapy were developed and were replacing laparotomy. We report a case of intractable pelvic pseudocyst treated successfully with ultrasound-guided cyst aspiration and sclerotherapy using acetic acid with a brief review of literature.

A 51-yr-old female was referred to our outpatient clinic for the evaluation of generalized edema. She had been diagnosed with idiopathic thrombocytopenic purpura (ITP). She had taken no medicine. Except for the ITP, she had no history of systemic disease. She was diagnosed with systemic lupus erythematosus. Immunosuppressions consisting of high-dose steroid were started. When preparing the patient for discharge, a generalized myoclonic seizure occurred at the 47th day of admission. At that time, the laboratory and neurology studies showed hyperglycemic hyperosmolar syndrome. Brain MRI and EEG showed brain atrophy without other lesion. The seizure stopped after the blood sugar and serum osmolarity declined below the upper normal limit. The patient became asymptomatic and she was discharged 10 weeks after admission under maintenance therapy with prednisolone, insulin glargine and nateglinide. The patient remained asymptomatic under maintenance therapy with deflazacort and without insulin or medication for blood sugar control.

BACKGROUND/AIMS: Many studies have compared patients with systemic lupus erythematosus (SLE) on renal replacement therapy (RRT) with non-lupus patients. However, few data are available on the long-term outcome of patients with end-stage renal disease (ESRD) secondary to SLE who are managed by different types of RRTs. METHODS: We conducted a retrospective multicenter study on 59 patients with ESRD who underwent maintenance RRT between 1990 and 2007 for SLE. Of these patients, 28 underwent hemodialysis (HD), 14 underwent peritoneal dialysis (PD), and 17 patients received kidney transplantation (KT). We analyzed the clinical outcomes in these patients to determine the best treatment modality. RESULTS: The mean follow-up period was 5 +/- 3 years in the HD group, 5 +/- 3 years in the PD group, and 10 +/- 5 years in the KT group (p = 0.005). Disease flare-up was more common in the HD group than in the KT group (p = 0.012). Infection was more common in the PD and HD groups than in the KT group (HD vs. KT, p = 0.027; PD vs. KT, p = 0.033). Cardiovascular complications were more common in the HD group than in the other groups (p = 0.049). Orthopedic complications were more common in the PD group than in the other groups (p = 0.028). Bleeding was more common in the HD group than in the other groups (p = 0.026). Patient survival was greater in the KT group than in the HD group (p = 0.029). Technique survival was lower in the PD group than in the HD group (p = 0.019). CONCLUSIONS: Among patients with ESRD secondary to SLE, KT had better patient survival and lower complication rates than HD and lower complication rates than PD. The prognosis between the HD and PD groups was similar. We conclude that if KT is not a viable treatment option, any alternative treatment should take into account the patient's general condition and preference.

OBJECTIVES: The aim of this study was to evaluate the reliability and validity of the Korean Version of the Diagnostic Interview Schedule for Children Version IV(DISC-IV), a highly structured diagnostic interview used to assess more than 30 psychiatric disorders in children and adolescents. METHODS: A total of 91 study subjects, including 67 subjects who visited the child and adolescent psychiatry outpatient clinic at our institution and 24 community-based subjects, were assessed using the Korean Version of the DISCIV. Clinical diagnosis was used as a gold standard for the examination of the validity of the DISC-IV. Forty-four of the study subjects were randomly selected for test-retest reliability measurement. RESULTS: The validity of the Korean Version of the DISC-IV showed kappa values ranging from 0.25 to 0.40 in the clinical sample and 0.65 to 1.00 in the community sample. The sensitivities varied according to the diagnostic categories, but the specificities were excellent for all diagnostic entities. CONCLUSION: The Korean Version of the DISC-IV showed good reliability and validity in Korean children and adolescents. The Korean Version of the DISC-IV might be a useful tool for assessing psychiatric disorders in children and adolescents.
