Objective To investigate the stability of immunophenotyping in the course of relapse or at treatment failure of patients with acute lymphoblastic leukemia(ALL) and that of immunophenotyping of positive minimal residual disease(MRD).Methods From Aug.2000 to Dec.2007,33 children with ALL who relapsed or treated failure were enrolled. These children were detected MRD by flow cytometry. The immunophenotyping of children who relapsed or treated failure were compared with that of initial therapy;the immunophenotyping of MRD relapsed was compared with that of initial therapy.Results 1.In 23 out of 27 cases (85.18%) with B-ALL,changed at least 1 antigen between diagnosis and relapse.Six children with CD45 down-modulation and 2 children with CD45 up-modulation.Two children with CD19 down-modulation and 1 child with CD19 up-modulation.Six children with CD34 down-modulation and 4 children with CD34 up-modulation. Five children with CD10 down-modulation and 7 children with CD10 up-modulation.2.Six children with T-ALL had the same expression in CD45 between relapse and treatment failure. 3.These were 15 children had the least 1 case MRD,25 cases MRD were detected,these was 1 case up-modulation in CD45,1 case down-modulation in CD19,2 cases up-modulation and 8 cases down-modulation in CD34,3 cases up-modulation and 6 cases down-modulation in CD10.Conclusions Immunophenotyping of children with ALL may change at relapse and treatment failure. The frequency of change in B-ALL is higher than that of in T-ALL,but the change can not impact the detection of MRD.

Objective To study the outcomes of AIDS intervention programs and to provide scientific evidence for developing pertinent strategy on intervention among men who have sex with men (MSM).Methods MSM were recruited through snowballing and investigated by face to face interview in 2006 and 2007 respectively.SPSS 12.0 was used to compare the change of cognition about AIDS,sexual behavior,prevalence rates of HIV and Syphilis before and after the intervention program among the population under study.Results The cognition about AIDS among MSM was obviously improved after the intervention with the rate increased from 74.3% to 82.4% (P=0.01).The rate of last time condom use among MSM increased from 56.4% to 65.5% (P=0.00).The rate of consistent condom use during six months among MSM increased from 31.8% to 41.9% (P=0.00).The rates of both condom use during commercial sex with men and with women did not change much among MSM.The prevalence rates of HIV in 2006 and 2007 were 10.4% and 10.8% and of syphilis in 2006 and 2007 were 9.3% and 7.3% respectively which were not significantly different between before and after the intervention.Conclusion The cognition about AIDS among MSM was improved obviously.However,the rate of consistent condom use was still low,reflecting the segregation phenomenon between their behavior and cognition.All our findings implied that it was crucial to carry out AIDS prevention and control programs.

OBJECTIVETo examine HIV prevalence and its associated factors among men who have sex with men (MSM) and provide the evidence for the intervention program among MSM.

METHODSA face-to-face questionnaire interview was conducted among MSM recruited by snowball sampling method in Yuzhong, Jiulongpo and Shapingba district of Chongqing from July to September, 2007. Totally, 1044 MSM were recruited. Associated factors with HIV prevalence were analyzed using forward stepwise logistic regression that HIV status was the dependent variable and demographics, AIDS awareness, sexual behaviors and the status of the intervention were independent variables.

RESULTSA total of 1044 MSM were surveyed. The rate of AIDS awareness was 89.5% among MSM. The rate of unprotected anal sex during the past 6 months was 63.8%. The prevalence of HIV and syphilis was 8.5% (89/1044) and 12.5% (131/1044) respectively. The multivariate analysis identified that the older MSM (OR = 1.69, 95% CI: 1.13 - 2.52), junior school education (OR = 1.89, 95% CI: 1.17 - 3.05), younger than 18 years old of the first sex (OR = 3.11, 95% CI: 1.20 - 8.02), more than 10 sexual partners (OR = 2.24, 95% CI: 1.24 - 4.02), the history of having sex with women (OR = 2.40, 95% CI: 1.64 - 3.51) and syphilis infection (OR = 4.52, 95% CI: 2.77 - 7.38) were independent risk factors associated with HIV infection.

CONCLUSIONThe rate of unprotected anal sex was high, so were the prevalence of HIV and syphilis among MSM. It should be urgent to conduct the intervention to stop AIDS rapid transmission among MSM.

Objective To investigate the clinical features and prognosis of acute pancreatitis(AP)complicated with metabolic syndrome(MS).Methods 139 AP patients were retrospectively selected and divided into MS group(76 cases)and non-MS group(63 cases),general data of the two groups were collected and analyzed;conservative treatment was given to 2 groups of patients,and the general conditions,laboratory indicators,comorbidities,and related indicators of disease severity of the two groups were compared and analyzed,and the influencing factors of poor prognosis in patients(AP combined with MS)were analyzed.Results Compared with non-MS group,HDL,Ca2+in MS group decreased significantly,Body weight、Body Mass Index(BMI)、diabetes mellitus、hypertension(systolic/diastolic blood pressure)、hyperlipidemia、white blood cell count、CRP、PCT、IL-6、FPG、UA、TC、TG、TyG、TYG-BMI and non-traditional lipid parameters TC/HDL-C、TG/HDL-C、LDL-C/HDL-C and non-HDL-C were significantly increased.There were no significant differences in age、sex、length of stay、BUN、CREA、LDL-C、ALT and AST between the two groups(P＞0.05);BMI,white blood cell count,CRP,IL-6,FPG,UA,TC,TG,TyG,TYG-BMI,TC/HDL-C,TG/HDL-C,LDL-C/HDL-C,and non-HDL-C were independent risk factors for poor prognosis in AP patients with MS,and HDL-C was a potential protective factor for prognosis in AP patients with MS,the difference was statistically significant(P＜0.05).Conclusion With the change of modern lifestyle,there are more and more MS patients,and the incidence of MS patients with AP is gradually increasing.TyG,TYG-BMI and non-traditional lipid parameters are novel,convenient and practical markers for clinical evaluation,which have a high diagnostic and predictive value for AP with MS metabolic abnormalities,and provides clinical basis for management and intervention.

Human-animal parasitic diseases caused by medical helminths are hazardous to human health. Genetic polymorphism studies on medical helminth populations can not only understand the biological characteristics and genetic structure of their populations, but also help reveal how they adapt to their parasitic environment, thus contributing to deepen our understanding of the epidemiological patterns of parasitic diseases and improve our understanding of accurate prevention and control of parasitic diseases. With the development of molecular biology, molecular markers such as DNA barcodes, simple sequence repeats, and single nucleotide polymorphism markers have been widely used to study the genetic relationships among parasite populations and individuals, and to reveal the genetic variation of parasite populations and the evolution of species origins. In this paper, we systematically review the application of three molecular markers commonly used in the study of genetic polymorphism in medical helminths, with a view to laying the foundation for related research.

OBJECTIVETo investigate the expression of the Wilms' tumor 1 (WT1) mRNA in childhood myelodysplastic syndrome (MDS), and to evaluate WT1 as a tool to differentiate MDS from aplastic anemia(AA).

METHODSThe quantitative expression of WT1 transcript by using real-time quantitative polymerase chain reaction (RQ-PCR) was performed in the bone marrow samples of 36 childhood MDS and 49 childhood AA, the samples were collected from September 2008 to December 2011.

RESULTS(1) The positive rate of WT1 in severe AA (SAA) was 0, 14.3% in chronic AA (CAA), 58.6% in refractory cytopenia (RC), 100% in refractory anemia with excessive blast (RAEB) and 97.5% in acute myeloid leukemia (AML). The mean level of WT1 in SAA, CAA, RC, RAEB and AML was 0.041%, 0.357%, 7.037%, 12.680% and 24.210%, respectively. The positive rate of WT1 in RC patients was higher than that of SAA (P = 0.000) and CAA (P = 0.001). (2) The positive rate of WT1 in patients with hypoplastic MDS was 66.7% and was higher than that of SAA (P = 0.000) and CAA (P = 0.001). The mean level of WT1 in patients with hypoplastic MDS was (3.022 ± 5.040)% and higher than that of SAA \[(0.041 ± 0.047)%, P = 0.000\] and CAA\[(0.351 ± 0.479)%, P = 0.002\].

CONCLUSIONSThe level of WT1 in childhood MDS was higher than that of childhood AA. The degree of WT1 expression in MDS increased during disease progression. WT1 is a useful tool for differentiating the childhood hypoplastic MDS from AA.
