OBJECTIVETo explore the outcome of remission induction chemotherapy (IC) and prognostic in elderly patients with acute myeloid leukemia (AML).
METHODSThe clinical data of 156 AML patients older than 60 years in the Institute of Hematology, Union Hospital of Fujian Medical University from January 2003 to July 2010 were analyzed retrospectively. 104 patients received cytarabine-based regimens, including protocol DA,IA or CAG,while 52 patients received palliative treatment. The median survival time was compared between patients with and without IC. The prognostic factors were evaluated by using univariate and multivariate analyses.
RESULTS145 (93%) cases were followed-up. The median survival time was 316 days in 96 IC patients, compared with 37 days in 49 PT patients (P < 0.01). Not receiving induction chemotherapy,high-risk karyotype,hyperleukocytosis (> or = 100 x 10(9)/L), Charlson Comorbidity Index (CCI) > or = 2 were adverse prognostic factors of the survival time with univariate analysis, and all were independent poor factors affecting the survival time with multivariate analysis.
CONCLUSIONSIC can improve outcomes in elderly AML patients. The patients with hyperleukocytosis (> or = 100 x 10(9)/L) , high-risk karyotype, CCI > or = 2 and without receiving IC have poorer prognosis.

Objective To understand the relationship between the concentration of air pollutants and daily emergency department visits for different diseases (circulatory system disease, digestive system disease, nervous system disease and respiratory system disease) in Guangzhou, Guangdong Province. Methods The daily average concentrations of sulfur dioxide (SO2), nitrogen dioxide (NO2, carbon monoxide (CO) and PM2.5 and the daily maximum 8-hour concentrations of O3, the daily average temperature, the relative humidity and cause -specific emergency department visits of the four major diseases from 2015 to 2017 were collected in Guangzhou. Semi-parametric generalized additive model was used to analyze the relationship between the concentration of pollutants and daily cause-specific emergency department visits. Results The daily average concentrations of SO2, NO2, CO, O3 and PM2.5 during the study period were 13.24 μg /m3, 45.96 μg /m3, 0.97 mg /m3, 123.77 μg /m3 and 36.22 μg /m3, respectively. For circulatory system disease,the independently significant associations of SO2 with emergency department visits in single-pollutant models (2.91%, 95% CI: 1.00%-4.85%), and multipollutant models (4.39%, 95% CI: 1.22%-7.67%) were observed. Conclusion The ambient SO2 increases the risk of emergency department visits due to circulatory diseases in Guangzhou. Comprehensive prevention and control measures should be taken to reduce the emission of SO2.

OBJECTIVETo explore the relationship between loss of heterozygosity (LOH) of 5p with the histological phenotype in gastric cancer.
METHODSEighty pairs of tumor and adjacent normal mucosa samples were collected and genomic DNA was extracted. Total of 17 polymorphic microsatellite markers for 5p were used for LOH analysis. A part of samples were fixed in 10% buffered formalin and stained with H&E. Histological type of gastric cancer was defined according to Lauren's classification.
RESULTSThe average informative rate of all seventeen markers was 60.0%. The LOH at least in one locus was detected in 28 of the 80 (35.0%) cases. The highest LOH frequency occurring at D5S2849 (7.77 cM), with LOH frequency of 35.2% (19/54). The minimal LOH region was spanned from 6.67 to 9.41 cM (1.18 Mb, covering 2.7 cM), including D5S417, D5S2849, D5S1492 and D5S2088. In 28 with LOH, 24 (85.7%) cases were of intestinal type, and only 4 cases (14.3%) were of diffuse type. There is significant difference between LOH frequency in intestinal-type and diffuse-type gastric cancers (P < 0.01). Searching the NCBI database disclosed that this minimal deletion region at 5p15.33 covered 3 candidate genes, IRX1, IRX2, and CEI.
CONCLUSIONThe molecular events in 5p 15.33 may be related with the morphological differentiation and development of gastric cancer. Gastric cancer with LOH of 5p15.33 locus tends to develop in to intestinal type. The cluster of candidate genes in 5p15.33 may be closely implicated in carcinogenesis of intestinal type gastric carcinoma.

OBJECTIVE:
To investigate polymorphism distribution of the 5 Y-SNP loci in Jinan Han population, and evaluate their potential in forensic application.
METHODS:
Genotyping of 5 Y-SNP loci (M89, M9, M122, M134, M95) were executed in the sample of 103 unrelated Chinese male individuals in Jinan Han population by using fragment length discrepant allele specific PCR (FLDAS-PCR).
RESULTS:
In 5 Y-SNP loci, genetic polymorphism were identified in Jinan Han population, and the ranges of gene diversity(GD) were 0.093 3-0.491 2. Twenty different haplotypes were observed and the haplotypes diversity (HD) was 0.867 9. Six different haplogroups were detected according to international association of Y chromosome nomenclature.
CONCLUSION
Five Y-SNP loci and their haplogroups in Jinan Han population are highly polymorphic, which can provide more information for the genetic structure analysis and forensic genetics research in the region.

CALLG2008 Protocol is sequential chemotherapy for adult acute lymphoblastic leukemia (ALL) established by Collaborative Group of adults acute lymphoblastic leukemia. It is emphasized that comprehensive treatment of adult ALL according to risk stratification is rather important. This study was purposed to evaluate the therapeutic efficacy of CALLG2008 for adult ALL. The clinical data of adult ALL patients of ≥ 14 years old diagnosed and treated by CALLG2008 Protocol were collected from May 1, 2009 to December 31, 2011 in Fujian Medical University Union Hospital, and the efficacy was analyzed. The results showed that 31 out of 33 cases of ALL achieved CR, the CR rate was up to 93.9%, the PR rate was 3.1%, and the total response rate was 97%. There were no uncontrolled severe toxicities, and no early deaths were observed. The overall survival (OS) at 1 year was only 66.7%,the relapse rate was 43.8% and the 1-year mortality was 33.3 %. This may be related with no-enough compliance, no-enough economical support and short follow-up time of the patients. The risk factor analysis showed that WBC level in newly diagnosed patients may influence the OS and relapse-free survival (RFS) of ALL. It is concluded that CALLG2008 protocol applied to adult ALL has a high remission quality and low mortality rate during the induction. The disease free survival (DFS) needs to be observed longer. It is essential to carry out MRD monitoring to determine the early recurrence and improving the long-term efficacy.

Objective To determine whether the combination of traditional risk factors and quantitative coronary angiography (QCA) assessment could provide accurate prognostic information on a population-based study including 1137 adults with subclinical artherosclerosis and with coronary risk factors. Methods Participants underwent coronary angiography examination before the minimal stenotic diameters, segment diameters, percent stenosis, plaque areas. Other parameters were analyzed by the computer-assisted Coronary Angiography Analysis System. The Framingham Risk Score for each participant was assessed. During the 1 year follow-up period, all kinds of endpoint cardiovascular events were screened. Endpoint events were defined as death from coronary heart disease, nonfatal myocardial infarction (MI) or unstable angina pectoris. Results During the 1 year of follow-up period, a total of 124 participants developed an endpoint event, which was significantly associated with the Framingham Risk Score, calcium of plaques and the plaque areas (all Ps<0.05).The QCA score incorporated with the QCA parameters was related to the endpoint events. The Framingham Risk Score was combined with QCA score through logistic regression for prediction of end-point events. Data from the ROC analysis showed the accuracy of this prediction algorithm was superior to the accuracy when variables themselves were used. The event-free survival rate was inferior to the control group in participates under high risk, when being screened with this prediction algorithm (P<0.05). Conclusion The risk of cardiovascular attack in subclinical artherosclerosis individual seemed to be associated with the Framingham Risk Score, calcium of plaques and the plaque areas. When the traditional risk factors (the Framingham Risk Score) were combined with QCA, the new method could provide more prognostic information on those adults with subclinical artherosclerosis.

OBJECTIVETo study the prevalence of severe acute respiratory syndrome coronavirus (SARS-CoV) like virus in animals at a live animal market of Guanzhou in 2004 before and after culling of wild animal action taken by the local authority, in order to predict the re-emerging of SARS from animal originals in this region.
METHODSAnimals at live animal market were sampled for rectal and throat swabs in triplicate. A single step realtime reverse transcription-polymerase chain reaction (RT-PCR) diagnostic kit was performed for screening SARS-CoV like virus, the manual nested RT- PCR and DNA sequencing were performed for confirmation. Only specimens which tested positive for both of the N and P genes by nested RT-PCR were scored as positive.
RESULTSIn 31 animals sampled in January 5 2004 before culling of wild animals at Guangdong Province, including 20 cats (Felis catus), 5 red fox (Vulpes vulpes) and 6 Lesser rice field rats (Rattus losea), 8 (25.8%) animals were tested positive for SARS-CoV like virus by RT-PCR methods, of which 4 cats, 3 red fox and one Lesser rice field rats were included. However, two weeks after culling of animals and disinfection of the market were implemented, in 119 animals sampled in January 20 2004, including 6 rabbits (Oryctolagus cuniculus), 13 cats, 46 red jungle fowl (Gallus gallus), 13 spotbill duck (Anas platyrhynchos), 10 greylag goose (Anser anser), 31 Chinese francolin (Franclinus pintadeanus), only rectal swab from one greylag goose was tested positive for SARS-CoV like virus. Furthermore, in 102 animals that including 14 greylag gooses, 3 cats, 5 rabbits, 9 spotbill duck (Anaspoecilorhyncha), 2 Chinese francolin (Franclinus pintadeanus), 8 common pheasant (Phasianus colchicus), 6 pigeons, 9 Chinese muntjac (Muntiacus reevesi), 19 wild boar (Sus scrofa), 16 Lesser rice field rats, 5 dogs, 1 mink (Mustela vison), 3 goats, 2 green peafowl (Pavo muticus) sampled in April, May, June, July, August and November, only rectal swab from one pig was tested positive. However, of 12 and 10 palm civets sampled in November and December including five of which had been at the live animals market for 2 days, none of them was tested positive.
CONCLUSIONThis findings revealed that animals being sampled in April, May, June, July, August and November of 2004, only one rectal swab from a pig was tested positive as SARS-CoV like virus, much lower than the results from the previous year, suggesting that the possibility of re-emerging of human infection from animal origins is low for the winter of 2004-2005.
