The study was aimed to investigate the changes of T-cell subgroups in the peripheral blood (PB) of patients with aplastic anemia (AA) and the relationships between these changes and the pathogenesis of AA and the immunosuppressive therapeutic effects in AA, in order to provide a basis for selecting rational therapy of AA patients. T-cell subtype and the ratio of CD4+/CD8+ cell in the PB of 88 AA patients which had been diagnosed clearly and given conventional therapy or conventional therapy combined with immunotherapy were analyzed by tri-colour fluorescence-labeled monoclonal antibody and using multiparameter flow cytometry. The patients with AA were divided into normal type of ratio, inverted type of ratio, hypernormal type of ratio according to the ratio of CD4+/CD8+ cell in normal group, and then the relations of these subtype with patients' conditions and therapeutic effects were investigated. The results showed that the percentage of normal type of ratio in all patients was 39.8%, the percentage of inverted type of ratio in all patients was 44.3%, The percentage of hypernormal type of ratio in all patients was 15.9%. In the conventional therapy alone, there was no significant difference on therapeutic effects among these three immunological subtypes. In combined immunotherapy, total therapeutic efficacy of AA patients with inverted type of ratio and AA patients with immunologic abnormality (inverted type + hypernormal type) was 84.2% and 82.6% respectively, which were more than that in conventional therapy (45.5% and 42.8%) (p < 0.05). Total therapeutic efficacy in these patients was better than that in AA patients with normal type. It is concluded that significant abnormal ratios of CD4+/CD8+ exist in the majority of AA patients, abnormal ratios of CD4+/CD8+ both may be showed as increase or decrease, immunologic abnormality may play a role in pathogenesis of the patients with AA. The detection of PB T-cell subtype in patients with aplastic anemia contributes to evaluation of patients' condition and choice of rational treatment prescription, and enhancement of diagnostic level and therapeutic efficacy significantly, which is an important indicator for therapeutic strategy also.

OBJECTIVETo study the prevalence of hypertension and glucose/lipid metabolism induced by chronic obstructive pulmonary disease (COPD) in hospitalized patients and their correlations to age and gender.

METHODSA retrospectively prevalence survey was conducted among the in-patients with COPD treated in General Hospital of PLA, Peking Union Medical College Hospital and Beijing Hospital between January 1st, 2000 and March 20th, 2010.

RESULTSA total of 4960 COPD patients were selected, including 3570 male and 1390 female patients with a mean age of 72.2∓10.4 years. Among these patients, hypertension had the highest prevalence (40.3%), followed by diabetes/impaired glucose tolerance (18.8%) and then by hyperlipidemia/fat protein metabolism (6.9%). The prevalence of hyperlipidemia/lipoprotein metabolism in the COPD patients over 80 years old decreased significantly with age. The prevalence of hypertension increased with age. In patients over 50 years old, the prevalence of hypertension was significantly higher in female than in male patients (P<0.05). The prevalence of diabetes/impaired glucose tolerance increased with age in male patients but decreased in female patients aged :80 years (P<0.05). Female patients in 60-69.9 and 70-79.9 years groups had significantly higher incidence of diabetes/impaired glucose tolerance than male patients (P<0.05), but not at older ages. The incidence of hyperlipidemia/lipoprotein metabolism disorder increased with age in both male and female patients aged below 80 years (P<0.05), but in 60-69.9 and 70-79.9 year groups, female patients had a significantly higher incidence than male patients (P<0.05); at the ages :80 years, the incidences was lowered in both women and men without a gender-specific differences (P>0.05).

CONCLUSIONSThe data we obtained concerning the prevalence of hypertension and glucose/lipid metabolism disorder, age distribution, and gender characteristics of the COPD patients provide a clear target for secondary prevention of COPD.

Objective To investigate the association of post-stroke depression (PSD) with gene polymorphisms of catechol-O-methyl transferase (COMT) Val1 08/158Met and dopamine transporter 40bp variable number of tandem repeats (VNTR) in dopamine metabolism system. Methods Sixty-eight patients with PSD and 91 patients only suffered from stroke, admitted to our hospital from January 2010to June 2010, were chosen; the gene polymorphisms ofCOMT Val108/158Met and DAT 40 bp VNTR were analyzed by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The genotypes of COMT gene amplifications were wild type (G/G),homozygous mutant type (A/A) and heterozygous type (A/G); 7 repeated genotypes (7/7, 9/7, 10/7, 10/9,10/10, 11/10 and 11/11) were noted in the DA T gene amplifications; frequencies of COMT alleles and genotypes were significantly different between the 2 groups (x2=5.703, P=0.017;x2=6.489, P=0.039). The frequencies of COMT alleles and genotypes were significantly different between the 2 female groups (x2=4.610, P=0.032;x2=6.547, P=0.024), but no significant differences were found between the 2 male groups (P＞0.05). The frequencies and heterozygosity of DAT alleles and genotypes showed no obvious differences between the 2 groups (P＞0.05). Conclusion The gene polymorphism of COMT Val108/158Met may be associated with PSD, while that of DAT 40bp VNTR is not.

OBJECTIVETo determine the self-compatibility of Platycodon grandiflorum and the location of microspore germination on stigma.

METHODThe microspore germination of self-pollination, self-plant-pollination and cross-pollination and the pollination microspore germination in and outside of stigma were observed with fluorescence microscopy.

RESULTMost pollens of self-pollination, self-plant-pollination and cross-pollination can germinate on the stigma, and after 24 hours, pollen tube entered into the ovary successfully. Pollinated on the outer-surface of stigma, microspores could not germinate, but on the inner-surface of the stigma when it dehisced most microspores can germinate.

CONCLUSIONThe compatibility of self-plant-pollination of Platycodon grandiflorum is high. The microspore germination loci is on the inner-surface of the dehisced stigma.

Objective To investigate the current status and influencing factors regarding quality of life among patients with Alzheimer' s disease (AD).Methods Through stratified cluster sampling method,two hundred patients with AD and their caregivers were chosen and interviewed.AD patients were assessed by questionnaires,Montreal Cognitive Assessment,and Quality of LifeAlzheimer' s Disease (QOL-AD),in order to compare the reports from patients and caregivers on QOL-AD and to analyze related influencing factors.Descriptive analysis,paired t-test,analysis of variance (ANOVA),Pearson' s correlation and multiple linear regression were performed using the Statistical Package for Social Science (SPSS).Results The scores of reports from patients (28.78 ±4.30) were lower than that from the caregivers' (30.05 ± 6.05).The difference was statistically significant (t=2.122,P＜0.05) and was positively correlated (r=0.312,P＜0.001).Data from multivariate analysis showed that cognitive level (t=3.465,P=0.001),marriage relationship (t=3.062,P=0.003 ),having public activities (t =2.581,P=0.011 ),personal characters (t =2.254,P =0.026),restricted diet pattern (t=3.614,P＜0.001),regularly drinking tea (t=2.652,P=0.009) and doing housework (t=3.180,P=0.002) were predictive factors.Conclusion Scores from the caregiver' s report on QOL-AD were higher than that from the patients'.Many factors influenced the quality of life on AD patients.Strategies on improving the quality of life among AD patients can be developed based on the findings of this study.

OBJECTIVEThis study was aimed to investigate the association between serum against Epstein-Barr virus (EBV) antibodies levels and nasopharyngeal carcinoma (NPC) patients' prognosis.

METHODSBlood samples from 140 primary NPC patients without metastasis were collected before and after treatment. The titers of VCA/IgA and EA/IgA were detected by immunoenzyme assay, and the levels of NA1/IgA and Rta/IgG were detected by enzyme-linked immunosorbent assay (ELISA). All patients received consequent follow-up and long-term efficacy and survival assessment.

RESULTSPost-treatment serum levels of VCA/IgA, EA/IgA, NA1/IgA and Rta/IgG in NPC patients significantly decreased than those before treatment, while had significantly higher than those in control individuals (P < 0.05). Patients in remission had significantly lower pre-treatment serum levels of VCA/IgA and EA/IgA than patients with progression (P < 0.05). None of serum levels of VCA/IgA, EA/IgA, NA1/IgA and Rta/IgG was associated with the 3-year overall survival (P > 0.05). The progression-free survivals were significantly lower in patients with higher pre-treatment VCA/IgA (> or = 1 : 320) and EA/IgA (> or = 1:80) levels than in those with lower VCA/IgA ( < 1 : 320) and EA/IgA (< 1 : 80) levels, respectively (61.8% vs. 86.5% , 61.3% vs. 86.5%, P < 0.001). Cox regression model analysis demonstrated that pre-treatment serum VCA/IgA level was an independent risk factor for progression-free survival (HR = 3.80, P = 0.001).

CONCLUSIONAnti-EBV VCA/IgA and EA/IgA might provide information regarding the prognosis of NPC patients.
