The medical records of all 12 patients diagnosed as chronic active Epstein-Barr virus (CAEBV) infection at our hospital were analyzed retrospectively.There were 7 males and 5 females with a median onset age of 28 years.CAEBV was characterized by fever,splenomegaly,hepatomegaly and lymphadenopathy,etc.The abnormalities of laboratory examination included liver dysfunction,thrombocytopenia,anemia and leucopenia.EBV-DNA detected by real-time polymerase chain reaction was (1.7 × 103-3.5 × 107) copies/μg DNA in peripheral blood mononuclear cell.Among them,the outcomes were death (n =5),lost to follow-up (n =2) and T cell lymphoma (n =1).It is necessary to improve our awareness of CAEBV infection because of its poor prognosis and high mortality.

Objective To investigate the effects of ω-3 fish oil lipid emulsion via vein on the inflammatory response,immune and organ function in patients with severe acute pancreatitis.Methods A total of 53 patients with severe acute pancreatitis were randomized into conventional therapy plus fish oil group (FO group) and conventional therapy group (CON group).The patients in FO group were treat with ω-3 fish oil lipid emulsion (0.2 g · kg-1 · d-1,10％) based on conventional therapy for 14 days.The level of C-reactive protein (CRP),TG and TC were detected before treatment and at day 7 and day 14 after treatment.CD4+,CD4+/CD8+ and C3,C4 were also detected at day 1 and day 14 after treatment.At the same time,acute physiology and chronic health evaluation Ⅱ score (APACHE Ⅱ score),intra-abdominal pressure,negative fluid balance time,enteral nutrition start-time and ICU stay time were observed and recorded.Results Forty-five out of 53 patients were finally recruited into results statistics.The level of CD4+,CD4+/CD8+ and C3 at day 14 after treatment in FO groups improved significantly than that in the CON group (P ＜0.05).The levels of CRP,intra-abdominal pressure and APACHE Ⅱ score at day 7 and day 14in FO group descended more obviously than that in the CON group (P ＜ 0.05).The negative liquid balance time in FO group (3.55 ±0.86) days was obvious shorter than that in CON group (4.61 ± 1.12) days,while enteral nutrition start-time (3.86 ± 1.17) days was significantly earlier compared with CON group (5.30 ± 1.61) days (P ＜ 0.05),however ICU stay time and 28 days mortality rate had no significant difference between the two groups.Conclusions ω-3 fish oil lipid emulsion can decrease the inflammatory response and the negative liquid balance time,improve the immune function and restore bowel function in severe acute pancreatitis patients.Therefore,it maybe provide a new and effective means for severe acute pancreatitis.

BACKGROUND: The direct ratio is formed between the size of osseous defect around implant and the required time of complete repair. It is viewed that bone implantation is suggested if osseous defect is larger than 1 mm, which benefits the bone regeneration and early fixation of implant.OBJECTIVE: To compare the effects between coralline granules and hydroxyapatite (HA) during union after immediate implantation.DESIGN: Group observation and controlled experiment was designed.SETTING: Department of Stomatology Renmin Hospital of Wuhan University.MATERIALS: HA coated implant, HA granule, coralline granule and 3adult mongrel dogs.METHODS: The experiment was performed in Department of Stomatology, Renmin Hospital of Wuhan University from August 2002 to April 2003.Under anesthesia, 6 foramens were drilled on femurs of 3 dogs (3 foramens on each side) to result in osseous defect. Coralline granules were embedded in the osseous defect around the implant in all of proximal ends (coralline granule group, CG group), HA granules were embedded in the osseous defect around the implant in all of distal ends (HA group) and nothing was embedded in the defect around the implant in the center (the control). One dog was sacrificed under anesthesia on the 2nd, 3rd and 4th months after operation successively and the samples were collected from the implanted section in each group for X-ray examination and scanning electronic microscopic observation.MAIN OUTCOME MEASURES: X-ray examination on implanted sections and scanning electronic microscopic observation on samples in each the 4th month, it was observed that implants and osseous tissue were closely integrated in CG group and HA group and there was still partial osseous on samples in each group: on the 4th month, it was discovered that the regenerated osseous tissue was matured completely in CG group and few coralline granule residue was left. In HA group, the regenerated osseous tissue was matured completely, but there was still a large amount of HA granules left and the granules had not been absorbed obviously. In the control group, the space appeared partially in the implanted cervical region.CONCLUSION: The implantation of artificial bone is suggested if the osseous defect around immediate implant is larger than 1 mm. As the implanting materials, coralline granules and HA granules act on the most advantageous guide activity. Coralline granules can be degraded and substituted with osseous tissue,but HA granules cannot be absorbed, which affects osseous reconstruction.
