Objective To evaluate the clinical efficacy and adverse effects of CAG regimen in treatment of primary, refractory and relapsed acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (MDS), and analyse the factors influencing long-term survival. Methods Sixty-one patients with AML ( primary, n = 27; refractory, n = 18; relapsed, n = 16) and 9 patients with MDS were treated with CAG regimen. Examinations on liver and renal function, electrocardiogram and bone marrow cytology were performed before and after treatment, and adverse effects of CAG were observed. Short-term efficacy was evaluated based on clinical manifestation, peripheral blood and bone marrow cytologic examinations. Patients were followed up, overall survival ( OS) and disease free survival ( DFS) were analysed, and long-term efficacy of CAG regimen was evaluated. The factors influencing long-term survival were analysed by Log-rank test of survival curve. Results After a course of treatment by CAG regimen, the total effective rate was 71% , and 34 patients (49%) experienced complete remission. The median time of follow up was 45 months, the median OS was 28 months, and the median DFS was 23 months. Age, level of lactate dehydrogenase (LDH), remission condition after a course of treatment by CAG regimen and adoption of HD-Ara-C regimen as consolidation treatment were influencing factors for OS and DFS. The dominant clinical adverse effects were bone marrow depression, with 13 d as the median duration of agranulocytosis ( neutrophil <0.5 ×10~9/L) and 9 d as the median duration of thrombocytopenia (platelet <20 ×10~9/L). Conclusion CAG regimen may lead to favourable therapeutic effects in treatment of primary, refractory and relapsed AML and high risk MDS, and may yield less adverse effects and better long-term therapeutic effects. Age, level of LDH, remission condition after a course of treatment and adoption of HD-Ara-C regimen as consolidation treatment are dominant influencing factors for survival.

It was demonstrated that there was significantly antigeni c drift in the influenza virus strains from Guangdong in 1996. It was the molecu lar basis of the variation on A、B、C、D and E domain encoded by HA gene, especi ally on A、C and E domain while the change of receptor binding domain played the slight roles in the 1996 influenza outbreak. In the other hand, the variation of No 145 and No 193 encoded by HA gene resulted in biological-feature changes of epidemical influenza isolates, which could be isolated and cultured by MDCK c ell-lines, but difficultly by embryonated-eggs.

Objective To investigate the safety of rituximab combination chemotherapy in the treatment of B-cell non-Hodgkin' s lymphoma (B-NHL) complicated with hepatitis B virus (HBV) infection,and assess the incidence of HBV reactivation reduced by prophylactic lamivudine.Methods A retrospective study of HBV-related markers,HBV-DNA and liver function was performed before and after rituximabcontaining treatment in B-NHL patients.Thirty nine B-NHL patients with HBcAb(+)/HBsAb(-) were divided into prophylactic group (14 cases) and control group (25 cases).The incidences of HBV reactivation,functional damage of liver were measured.Results Among the 108 B-NHL patients who received rituximab combinatio nchemotherapy,15 (13.89 ％) were HBsAg (+) and 39 (36.11％) HBsAg (-) / HBcAb (+).Of the 15 HBsAg (+)patients,2 (13.3 ％) experienced reactivation of HBV.The prevalence of HBV reactivation was 7.7 ％(1/13) in patients who received prophylactic antiviral treatment and 50 ％ (1/2) in those who did not receivelamivudine.Among the 39 HBsAg (-) / HBcAb (+) patients,3 cases (7.7 ％) experienced reactivation of HBV.The prevalence of HBV reactivation was 0 in patients who receivcd prophylactic lamivudine treatment and 12 ％ (3/25) in those who did not receive this antiviral drug.Conclusion Prophylactic lamivudine before rituximab combination chemotherapy can reduce HBV reactivation obviously.

Baseline wander (BW) is a common noise contaminating electrocardiogram (ECG). In order to effectively correct baseline of ECG signal and to preserve more latent components of ECG signal, this paper proposes a simple and novel filter based on statistically weighted moving average. Firstly, after the arrange between the maximum and the minimum of these sampling values in a moving window was divided into many sections with equal width, several segments [a(k), b(k)] including most samples were determined. Then, for every sample point in the moving window its weight was decided according to the criterion: its weight was set as 1 if the sampling value belongs to [a(k), b(k)], otherwise, as 0. Lastly, all these ECG sampling points with 1 weight were averaged to estimate the real baseline in the moving window. The algorithm was tested by simulated signal and real signal from www. physionet. org. The results showed that compared to traditional moving average filter and wavelet package (WP) translation, the proposed filter could more effectively correct baseline in ECG signal and result in less distortion to ECG signal.

OBJECTIVETo design an animal model to study the facial transplantation of allografts in rabbits.

METHODSLivid blue rabbits and New Zealand white rabbits was applied as experiment animal, to harvest hemifacial composite-tissue flap based in the common external carotid artery with the branch of the external mandibular artery and auricularis magna artery, then allotransplantation was performed with the livid blue rabbits as recipient while new Zealand rabbits as donor, the immunosuppressive agent comprised ciclosporin, azamun and prednisone. 25 couples of rabbits were divided three groups. Group A, 5 couples of rabbits, no administered immunosuppressive agent and the artery anastomosis with end-to-end. Group B, 10 couples of rabbits, administered immunosuppressive agent and the artery anastomosis with end-to-end. Group C, 10 couples of rabbits, administered immunosuppressive agent and the artery anastomosis with end-to-side. Postoperative, to observe the survive ratio of animal and composite-tissue flap, verified the practicability of model further.

RESULTSThe blood supply of hemifacial composite-tissue flap is rich after allotransplantation. The survive ratio wasn't different with different procedure of the external carotid artery anastomosis.

CONCLUSIONSThis is a successful model of composite face flap transplantation in the rabbits.

OBJECTIVETo analyse the distribution, drug resistance and epidemiology of pathogenic bacteria in the burn wards of Ruijin Hospital.

METHODSSeventeen strains of Methicillin resistant staphylococcus aureus (MRSA), 52 strains of Pseudomonas aeruginosa (PA), and 11 strains of Acinetobacter baumannii (AB) isolated from the wound secretion, venous catheters, blood, urine and stool etc. were collected from burn patients hospitalized in our department from January 2004 to December 2006. The distribution and the drug resistance profile of bacteria were analyzed, and the homology analysis was performed by randomly amplified polymorphic DNA (RAPD).

RESULTSMRSA, PA and AB were the major strains in our burn wards in recent years, of which Staphylococcus aureus (SA) was the most dominant. During these 3 years, MRSA accounted for 77% (63/82), 85% (63/74), and 75% (74/99), respectively, for SA isolated in this period. MRSA was resistant to Amikacin, Gentamicin, Erythromycin, Clindamycin and Levofloxacin; PA was resistant to Amikacin, Gentamicin, Piperacillin, Ceftazidime, Cefoperazone, Aztreonam and Imipenem; AB was resistant to Amikacin, Gentamicin, Piperacillin, Ceftazidime, Imipenem and Ciprofloxacin. Three bacteria were found to belong to the same type in the RAPD homology analysis.

CONCLUSIONSThere are many kind of multi-drug resistant pathogenic bacteria for nosocomial infection in our burn wards. To control the spread of infection due to above-mentioned 3 bacteria is the focus of nosocomial infection control.

The large amount of repeats, especially high copy repeats, in the genomes of higher animals and plants makes whole genome assembly (WGA) quite difficult. In order to solve this problem, we tried to identify repeats and mask them prior to assembly even at the stage of genome survey. It is known that repeats of different copy number have different probabilities of appearance in shotgun data, so based on this principle, we constructed a statistical model and inferred criteria for mathematically defined repeats (MDRs) at different shotgun coverages. According to these criteria, we developed software MDRmasker to identify and mask MDRs in shotgun data. With repeats masked prior to assembly, the speed of assembly was increased with lower error probability. In addition, clone-insert size affect the accuracy of repeat assembly and scaffold construction, we also designed length distribution of clone-inserts using our model. In our simulated genomes of human and rice, the length distribution of repeats is different, so their optimal length distributions of clone-inserts were not the same. Thus with optimal length distribution of clone-inserts, a given genome could be assembled better at lower coverage.
