Objective To construct a eukaryofic expression vector for A PP695 gene carrying green fluorescence protein (GFP) gene. Methods RT-PCR was used to amplify the full-length APP695 cDNA. The PCR products and the eukaryotic expression vector pIRES2-EGFP were digested by restriction endonueleases, and the digested APP695 gene was inserted into the digested eukaryotic expression vector. The positive recombinants were identified by PCR analysis, Nhe Ⅰ and Hind Ⅲ digestion and sequence analysis. Results The 2088-bp DNA fragment was amplified by PCR from the plasmid pCB6, and an identical DNA fragment was also amplified from the recombinants. The products of double restriction enzyme digestion were A PP695 gene with a 5.3-kb DNA fragment. Sequence analysis confirmed successful insertion of A PP695 gene into pIRES2-EGFP vector. Conclusion The eukaryotie expression vector pIRES2/APP695-EGFP has been successfully constructed.

AIM:To investigate the difference of non - invasive tearfilm break - up time (NIBUT) by Keratograph 5M beforeand after forced eye opening in healthy individuals.METHODS: Prospective case self - control study. Fortynormal volunteers (79 eyes ) were enrolled.

The average of NIBUTf andNIBUTav were 8. 91士5. 54s, 11. 76士5. 58s and percentage ofdry eye at different levels were 35% , 48% , 16%respectively after forced eye opening. There was nosignificant difference on NIBUT and dry eye level byOculus keratograph 5M in normal subjects (t = 0. 37, P =0 72; t = -0. 038, P = 0. 97; Z = -0. 42, P = 0. 68).CONCLUSION: There is no influence on NIBUT and dryeye level by detected Keratograph 5M before and afterforced eye opening in healthy subjects.

OBJECTIVETo summarize the histological and clinical characteristics of 40 cases with Burkitt's and Burkitt-like lymphoma in children, to evaluate the effects of treatment with international regimen, and to explore the treatment-related complications and prognostic factors.

METHODSForty patients with Burkitt's and Burkitt-like lymphoma were registered in Beijing Children Hospital from Feb 2003 to Apr 2006. The diagnosis was confirmed by histology and immunohistochemistry of biopsy, and clinical staging by the examination of imaging, cerebrospinal fluid and bone marrow based on St. Jude system. Intensive, short-term chemotherapy witch was modified from LMB89 protocol was given to the patients.

RESULTSOf the 40 patients, 30 were diagnosed as Burkitt's lymphoma (BL) and 10 as Burkitt-like lymphoma (BLL). Antibody against Epstein-Barr virus (EBV-Ab) was positive in 19 cases at diagnosis, only 7 of the patients were positive for EBER. Thirty-three of the cases were male and 7 female (M:F = 4.7:1); the median age was 6 years 9 months. The most frequently seen clinical characteristics were abdominal masses and surgical abdomen. Nine cases were at stage I - II and 31 cases at stage III - IV at diagnosis; CNS was involved in 4 cases and bone marrow in 2 cases. The courses of treatment were approximately 2 - 8 months. All the patients were followed up, the median follow-up period was 22.6 months. After chemotherapy, 35 patients (88.7%) were still alive during the one-year follow-up. The 3-year event-free survival (EFS) rate was 81.8%. Major toxicity was myelosuppression and mucositis. Stage III to IV of myelosuppression occurred in the most patients with unresected tumor and CNS-involvement. Of 5 patients who died, 2 died of infection, 2 died of lymphoma progression during chemotherapy, and 1 died of relapse.

CONCLUSIONBurkitt's and Burkitt-like lymphoma are the most common NHL in children with rapid clinical process. Outcome was greatly improved by current intensive, short-term chemotherapy regimen, the 3-year EFS was 81.8% including the patients who were in advanced stage. Childhood lymphoma with short clinical history, stage IV and residual disease after 3 months of therapy are associated with poor prognosis.

OBJECTIVETo study the risk factors in high prevalence district of birth defects (BD) to provide evidence for intervention development.

METHODSQuantitative analysis had been carried out based on the investigation at three counties in Shanxi province. 491 useable questionnaires had been collected with a response rate as 94.6%. Binary logistic regression was performed to analyze the risk factors of BD.

RESULTSData from logistic regression analyses revealed that factors as: the status of family income, knowledge on healthy birth and rearing, behavior and illness during pregnancy were influencing the occurrence of BD, with OR values as 0.535, 3.265, 0.403 and 1.379 respectively. Better family income and knowledge on BD were negatively (P values are 0.000 and 0.001 respectively), while illness during pregnancy and alcohol intake of the husbands were positively correlated (P values are 0.005 and 0.012 respectively) to the occurrence of BD.

CONCLUSIONMeasures as accelerating the development of local economy, providing education on BD knowledge to the couples, changing negative life style and improving the health status would reduce the risk of BD. Preconceptional-periconceptional care seemed to be the new idea for healthy pregnancy and healthy baby.

OBJECTIVETo explore safety, indications and advantages of mapping and ablation of arrhythmia in children guided by Carto and Ensite system.

METHODSGuided by Carto system, radiofrequency catheter ablation (RFCA) was performed on 8 pediatric patients with tachycardia whose mean age was (6.2 + or - 1.7) years, mean weight was (18.0 + or - 2.0) kg. Guided by Ensite system, RFCA was performed on 10 pediatric patients with arrhythmia, 8 of them were ablated guided by Ensite Array system: 6 cases with premature ventricular contractions (PVCs), 2 cases with right atrial tachycardia, their mean age was (11.3 + or - 1.2) years, and mean weight (40.0 + or - 5.0) kg. The other two cases with W-P-W syndrome were ablated guided by Ensite Navx system.

RESULTGuided by Carto system, 8 cases were successfully mapped and ablated: 6 cases had incision atrial tachycardia, 1 case had left atrial tachycardia and 1 case had right atrial tachycardia. In 1 case with incision atrial tachycardia the condition recurred after 3 months, and was ablated again successfully. Guided by Ensite Array system, 6 cases with PVCs (in 2 originating from the right ventricular inflow tract and in 4 originating from the right ventricular outflow tract) and 2 cases with right atrial tachycardia were successfully mapped and ablated, PVCs of the first 6 cases were reduced from (32 333 + or - 4509) 24 h to (0-4)/24 h after ablation. In 1 case with automatic atrial tachycardia, mapping could not be done by Ensite Array system, because P wave could not be identified from T wave. Single bolus of adenosine 20 mg was given within 30 s to let ventricles stop for 2 s (cardio-ventricular pacing standby) until T wave vanished, mapping and ablation were operated again successfully, but another atrial tachycardia occurred 1 day later. Guided by Ensite Navx system, 2 cases with W-P-W syndrome were successfully ablated, operation under X-rays lasted for 8 and 10 min. In none of the 9 patients the disease recurred after follow-up for 6 months.

CONCLUSIONCarto system is suitable for mapping and ablation in pediatric patients with continuous tachycardia, especially with incision atrial tachycardia; Ensite Array system fits children older than 10 years with right heart discontinuous arrhythmia; and Ensite NavX system can set up model and display endocardial anatomic structure quickly. Compared with two-dimensional mapping system, the three-dimensional mapping system (Carto and Ensite) can display the origin of arrhythmia and activation sequence clearly, decrease difficulty of operation efficiently and diminish operation time under X-ray.
