Objective To report 6 cases of hydroa vacciniforme-like cutaneous lymphoma,and to inves- tigate the relationship between this disorder and Epstein-Barr virus(EBV)infection.Methods Pathological and immunohistochemical examinations were performed in the biopsy specimens obtained from all 6 patients. Skin lesions were subjected to EBV encoded RNA(EBER)detection by in situ hybridization.Serological assay and quantification of EBV DNA were performed.Results All the 6 patients had recurrent papules, papulovesicles,necrosis and variola-like scar with chronic intermittent fever;four of the patients also presented with edema of the face,hands and feet.Pathologically,there were multilocular vesicles in the epidermis,and large numbers of infiltrating lymphocytes through the dermis.The cells were atypical with mitotic figures. Immunohistochemical staining of the lesions of 4 patients showed large quantities of cells expressing CD56, scattered cells expressing CD3 and CD45RO,and cells expressing grazyme B and T cell intracellular antigen-1 (TIA-1);a diagnosis of hydroa vacciniforme-like cutaneous NK/T lymphoma was made in these 4 cases. In the lesions of another 2 patients,the cells expressing CD3 and CD45RO,but not CD56,were observed; the diagnosis of hydroa vacciniforme-like cutaneous T-cell lymphoma was made in them.EBER was detected in the tumor cells of all the 6 patients.The IgG titers of anti-Epstein-Barr viral capsid antigen increased in all patients(1:5120 in 2 cases,1:2560 in 2 cases,1:1280 in 2 cases).The copies of EBV DNA were increased in the peripheral blood of both the two detected cases.A chronic active EBV infection was confirmed in all patients.Conclusions Hydroa vacciniforme-like cutaneous lymphoma is clinically characterized by edema of face,hands and feet,vesicular eruptions and variola like scars;histologically,it is characterized by infiltrates of atypical cells consistent with lymphoma,and necrosis in the center of vessels.NK/T is the primary immunophenotype of this disease.There is a close association between chronic active EBV infection and hydroa vacciniforme-like cutaneous lymphoma.

OBJECTIVETo investigate the influence of the rate of morphologically normal sperm (MNS) on the clinical outcomes of conventional in vitro fertilization (IVF) in patients with one retrieved oocyte.
METHODSFrom January 2013 to January 2015, a total of 256 couples with one retrieved oocyte underwent conventional IVF in our center. According to the rate of MNS, the patients were divided into two groups: MNS < 4% (134 cycles) and MNS ≥ 4% (122 cycles). We compared the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo between the two groups. A total of 75 fresh embryo transfer cycles were performed, 43 in the MNS < 4% group and the other 32 in the MNS ≥ 4% group. We also compared the rates of implantation, clinical pregnancy and abortion between the two groups.
RESULTSThere were no statistically significant differences between the two groups in the rates of no transferrable embryo cycles, fertilization, cleavage, normal fertilization, abnormal fertilization, high-quality embryo and transferrable embryo (P > 0.05). The rates of implantation, clinical pregnancy and abortion exhibited no remarkable differences either in the fresh embryo transfer cycles between the two groups (P > 0.05).
CONCLUSIONThe rate of MNS does not affect the clinical outcomes of conventional IVF in patients with one retrieved oocyte.

OBJECTIVETo study the changes of cardiac function following treatment with granulocyte colony stimulating factor (G-CSF) in patients with heart failure after myocardial infarction.
METHODSThirty-eight patients with heart failure after myocardial infarction were randomized into G-CSF treatment group and control group. All the patients received conventional treatment (medication and interventional therapy), and the patients in treatment group were given additional G-CSF (600 µg/day) for 7 consecutive days. The plasma level of brain-type natriuretic peptide (BNP) and the number of endothelial progenitor cells (EPCs) in the peripheral blood were detected before and at 7 days and 4 months after the treatment. The cardiac functions (LVSD, EDV, and LVEF) were evaluated by ultrasonic imaging before and at 2 weeks and 4 months after the treatment.
RESULTSThe number of EPCs was significantly higher in the treatment group than in the control group after the treatment especially at 7 days (P<0.01). In both groups, BNP level was lowered significantly after the treatment to recover the normal level (P<0.01). The cardiac functions were improved in all the patients at 7 days and 4 months after the treatment, and the improvement was more obvious in the treatment group (P<0.05), especially in terms of LVEF at 4 months after the treatment (P<0.01).
CONCLUSIONEPC mobilization by G-CSF can effectively improve the cardiac functions and lessen ventricular remodeling in patients with heart failure after myocardial infarction.

OBJECTIVETo explore the relationship between Helicobacter pylori (Hp) infection and iron status using serum ferritin (SF) as a marker for total iron and to identify the related factors of iron nutritional status among preschool children.
METHODSBy cluster sampling, we recruited 475 preschool children aged 2 to 7 years. A structured questionnaire and diet form were sent to the parents of these children to obtain related information about the socioeconomic level and dietary intakes. After collecting blood samples, the following indexes were measured. Hp IgG antibodies were measured with a dot enzyme-linked immunoassay; hemoglobin, Hct, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width index (RDW) with automatic Complete Blood Count; SF with an immunoradiometric assay. Stool Hp antigen and occult bleeding were measured with ELISA among individuals who were Hp seropositive. Hp status was defined as positive when both serum and stool antigen tests were positive, Hp status was defined as negative when serum antigen test was negative; 24-hour weighting and recording methods were used to dietary survey for three days in May and December 2001, respectively, dietary intakes including energy, protein and micronutrient were calculated using nursery school nutrition software and evaluated by Chinese Dietary Reference Intakes (DRIs). Mann-Whitney test was used to compare mean ranks of SF in Hp-positive and Hp-negative children. To obtain an adjusted estimate of the impact of Hp infection on SF, a multivariate analysis of covariance was done to evaluate the different level of SF between Hp infected and non-infected status. The relationship between iron deficiency and gender, age, socioeconomic condition, iron intake, and calcium intake was assessed by univariate analysis. An unconditional multivariate logistic regression analysis was also performed. Iron deficiency status was dichotomized and placed as the dependent variable. Hp infection status was incorporated together with possible confounding factors as independent variables in a final logistic regression model. All the data were managed by EPI Info 5.01a and analyzed by SAS (Version 6.12).
RESULTSTotally 64 children were diagnosed as Hp-positive and 305 as Hp-negative. Mann-Whitney test and multivariate analysis of covariance both showed that SF concentration was significantly lower in Hp infected individuals than non-infected individuals. Adjusted mean level and 95% confidence interval of SF in infected and non-infected children was 23.62 microg/L (7.13 microg/L-78.26 microg/L), 33.48 microg/L (10.28 microg/L-109.06 microg/L), respectively. The relationship between Hp infection and iron deficiency status persisted in logistic regression analysis after adjusting for possible confounding factors (OR: 7.95; 95% CI 2.56 - 24.67).
CONCLUSIONIron nutritional status was reduced in Hp infected preschool children. Hp infection appears to be an independent risk factor or an added stressor on iron status among preschool children.
