Objective To investigate the functioning of outpatients with chronic diseases. Methods 61 outpatients were investigated with the World Health Organization Disability Assessment Schedule 2.0 (WHO-DAS 2.0) Chinese version. Results All the outpatients expressed slight barriers in fields of understanding and communicating, moving and getting around, self-care, interacting with other people, domestic responsibilities, and joining in community activities. The outpatients with musculoskeletal and cutaneous diseases were more difficult in interacting with other people than other patients (P<0.05). Conclusion There are slight barriers in the outpatients with chronic diseases in activities and participations, which may be various with the diseases.

Objective To report a case of psoriasis vulgaris associated with acute myelogenous leukemia(AML)(type M4EO).Methods Clinical data from the patient were collected.Histopathologic examination,and examination of bone marrow and peripheral blood smear were performed.The immunologic types of bone marrow cells were analyzed with FACS.Chromosome and G-banding analyses were carried out with cultured bone marrow cells.Results A33-year-old woman had a history of chronic plaque psoriasis for20years.Her cousin had the same disease history.The patient was treated with various therapeutic regi-mens,most of which were traditional Chinese medicines.Recently the patient suffered from myalgia and chest bone pain,periodic bleeding on gums,fever and so on.The abnormal infantile monocytes and promye-locytes were found with bone marrow smear,and crassitude basophilic granules were noticed in eosinophils.The diagnosis of acute myelogenous leukemia type M4EO was made.The diagnosis was confirmed with the immunologic analysis of born marrow cells with FACS.Chromosome and G-banding analyses revealed her karyotype of46,XX,inv(16)/47,XX,inv(16),+8(2/22).The plaque lesions of psoriasis were regressed after allogeneic bone marrow transplantation and the symptoms of AML were resolved.Conclusion It is the first case report of psoriasis vulgaris associated with acute myelogenous leukemia M4EO which responded to allogeneic bone marrow transplantation.

BACKGROUND: Propranolol is a nonselective competitive adrenergic β-receptor blocker capable of suppressing sympathetic nerve excitation. Postmenstrual osteoporosis may be associated with the changes of sympathetic nerve activity.OBJECTIVE: To observe the effect of propranolol on tibial morphology in ovariectomized rats, and compare it with that of estrogen medication.DESIGN: Completely randomized design and controlled experiment.SETTING: End ocrinology Department, General Hospital of Beijing Military Area Command of Chinese PLA.MATERIALS: This experiment was conducted at the animal laboratory of the Institute of Basic Theory Research of Traditional Chinese Medicine between March 2002 and April 2003. Forty female unmated SD rats aged 6 months were included and randomized into 4 groups with 10 rats in each group: sham-operation group, estrogen medication group, propranolol treatment group, and placebo group.METHODS: ① Rats in estrogen group, propranolol treatment group and placebo group were anesthetized before the abdomen was opened and bilateral ovaries were excised. Rats in sham-operation group had their abdominal cavity opened and a piece of ovary surrounding fattytissue excised before closing the abdomen. ② Estrogen medication group: Rats were given hypodermic injection of grain oil dissolved 17 β-estradiol at a dose of 20 μg/(kg·d). Propranolol treatment group: Propranolol was used for gastric infusion at a dose of 18 mg/(kg·d). Placebo group and sham-op-eration group: The same volume of grain oil and/or distilled water was used instead of hypodermic injection or gastric infusion. Two treatment groups were given the same intervention as placebo group and sham-operation group during treatment; medication was carried out from postoperative week 1 for altogether 12 weeks. ③ Leica Qwin imaging analysis system was used for morphological measurement of bone tissues so as to calculate the volume percentage, active-surface formation percentage, mineralization rate, and formation rate of bone trabecula. ④ t-test was used for comparing the differences.MAIN OUTCOME MEASURES: Comparison of rat tibial morphological parameters between groups.RESULTS: Forty rats were divided into four groups with 10 rats in each and all entered the result analysis. ① Left tibial active-surface formation percentage and mineralization rate of bone trabecula: They were obviously lower in sham-operation group and estrogen group than in placebo group (P ＜ 0.01), but obviously higher in propranolol treatment group than placebo group (P ＜ 0.05). ② Formation rate of left tibial trabecula: It was obviously higher in propranolol treatment group than in placebo group (P ＜ 0.05). ③ The volume percentage of left tibial bone trabecula: It was obviously higher in sham-operation group and propranolol treat ment group than in placebo group (P ＜ 0.01), but obviously lower in pro pranolol treatment group than in sham-operation group and estrogen group (P ＜ 0.01). CONCLUSION: Propranolol can increase bone mass, reduce bone loss, and promote bone formation in osteoporotic rats following ovariectomy, thus displaying obvious preventive and therapeutic effects on osteoperesis in rats.

Objective To investigate the prevalence of primary HIV-1 genotype drug-resistance and viral subtype from 237 treatment-naive patients in China.nethods CD4+ T cell counts,plasma HIV-1 viral load and HIV-1 gene sequencing in total 237 treatment-naive patients enrolled from 20 provinces/regions were detected for the evaluation of primary HIV genotypic drug-resistance.Results The survey of 237 treatment-naive patients from muhicenter areas including Henan Province,Yunan Province,and Shanghai showed that 9 subtypes of HIV-1 strains were finally identified.Most of patients were infected before 2003.Only 3 cases had genotypic mutations associated resistance to antiretroviral drugs,with high resistance to nucleoside reverse transcriptase inhibitors(NRTIs),moderate resistance to protease inhibitors(PIs)and high resistance to non-nucleoside reverse transcriptase inhibitors(NNRTIs).respectively.The prevalence of primary genotypic drug resistance was 1.3%(3/237)in this study.Conclusions The rate of HIV-1 primary genotypic drug-resistance is still relatively low in treatment-naive HIV/AIDS patients while 9 subtypes of HIV-1 strain was diseovered.

To investigate the different reconstitutional profiles for acquired(CD4+ T cell)and innate(NK cell,γδT lymphocyte)immunity after highly active antiretroviral therapy(HAART).Methods The CD4+ CD4+,CD3+ CD4- CD8-,CD3- CD16/CD56+,CD4+ CD45 RA+ CD62 L+ and CD4+ CD45 RA- subsets were measured by flow cytometry.The dynamic changes of these subsets after HAART initiation were assessed in 59 patients who were followed for 12 months in resular 3-month visits.Results At baseline the cell counts of CD4+ T cells including its na(I)ve and memory subsets,NK cell and γδT cells in HIV/AIDS patients were all significantly lower than those of healthy individuals.There was a decrease of 2.33 lg copies/ml in HIV-1 RNA from baseline noted 1 month after initiation of treatment which was sustained through 12 months.CD4+ T cell count showed a bi-phase increase during treatment.The first rapid increase was mainly memory CD4+T cells and this followed by the second slow but steady increase of na(I)ve CD4+ T cells.Increases in NK cell and γδT cell were noted at 3 months of HAART and this restoration were different quantitatively when compared with the oge in CD4+ T cells.Conclusion HAART could induce a different quantitative restorational patterns in peripheral CD4+ T cells,NK cells and γδT cells.

Objective To analyze the correlation between CD4+ T cell count and HLA-DR or CD38 expression on peripheral CD8+ T cells in treatment-naive Chinese HIV/AIDS patients.Methods A total of 471 treatment-naive HIV-infected patients and 53 healthy volunteers were enrolled.HLA-DR or CD38 expression on peripheral CD8+ T cells, CD4+ T cell count, naive CD4+ T cell subsets and CD28 expression on T cells were measured by flow cytometry.Plasma HIV RNA load was quantified by real-time PCR (COBAS TaqMan RT-PCR).Mann-Whitney U test and Spearman's rank correlation test were used for statistical analysis.Results CD38 expression intensity on CD8+ T cells was negatively correlated with CD4+ T cell count (r =-0.53, P ＜ 0.001) and naive CD4+ T cell count (r =-0.48, P ＜ 0.001).CD38 expression on CD8+ T cells also displayed significantly negative correlation with CD28 expression on CD8+ T cells (r =-0.46, P ＜ 0.001).HLA-DR expression on CD8+ T cells did not show significant correlation with CD4+ T cell count.Only weak positive correlation was found between CD38 intensity on CD8+ T cells and plasma HIV RNA load.Conclusions Compared with HLA-DR, CD38 expression on CD8+ T cells shows more significant negative correlation with CD4+ T cell count in treatment-naive patients.CD38 and HLA-DR may play different roles on the persistent immune activation in HIV infection.

Objective To evaluate the accuracy of lymphocyte count as a surrogate for CD4+T cell count in treatment-na(i)ve HIV-infected adults.Methods A total of 2 013 HIV-infected patients were screened at 23 sites in China.CD4+ T cell counts were measured by flow cytometry.Correlation between CD4+ T cell count and peripheral lymphocyte count were analyzed by spearman coefficient.AUCRoc were used to evaluate the performance of lymphocyte count as a surrogate for CD4+ T cell count.Results The lymphocyte count and CD4+T cell count of these 2 013 patients were (1 600±670) × 106/L and (244 ± 148) × 106/L respectively.CDa+ T cell count were positively correlated with lymphocyte count(r =0.482,P ＜0.000 1).AUCROC of lymphocyte count as a surrogate for CD4+ T cell counts of ＜ 100 × 106/L,＜200 × 106/L and ＜ 350 × 106/L were 0.790 (95％ CI 0.761-0.818,P ＜ 0.000 1),0.733 (95％ CI 0.710-0.755,P ＜ 0.000 1) and 0.732 (95％ CI 0.706-0.758,P ＜ 0.000 1) respectively.Conclusion Lymphocyte count could be considerad as a potential surrogate marker for CD4+ T cell count in HIV/AIDS patients not having access to T cell subset test by flowcytometry.

Objective To observe the migration and inhibition mechanism of MicroRNA218-Robo1 pathway for breast cancer.Methods A total of 40 BALB/c-nu/nu female mice were randomly divided into four groups.Each group was transfected over-expression MicroRNA218 MDA-MB-231 breast cancer cells, co-over-expression MicroRNA218 and Robo1 MDA-MB-231 breast cancer cells, knock-down Robo1 MDA-MB-231 breast cancer cells and the control MDA-MB-231 breast cancer cells.The tumor volume was examined every two weeks.Results Tumor volume of MicroRNA218 group was obviously less than control group, tumor volume of Robo1 knock out group was obviously less than common MicroRNA218 high expression and Robo1 group, the difference was statistically significant;MicroRNA218 and Robol knockout group than the control group, the increase in breast cancer cells apoptosis, cell proliferation and angiogenesis is restrained.Conclusions MicroRNA218 inhibited the migration of breast cancer by down-regulating the expression of Robo1.

Objective To evaluate the influence of long-term nucleotide reverse transcriptase inhibitors (NRTIs) on lipids metabolism in HIV/AIDS patients and correlating clinical factors.Methods A total of 118 HIV/AIDS patients were divided into 3 groups:untreated group (40 patients),highly active antiretroviral therapy(HAART) for 1-2 years group (37 patients) and HAART over 5 years group (41 patients),with 20 healthy individuals as the control group.Clinical lipodystrophy (LD) was defined as concordance between patient's report of change and physical examination.Fat mass (FM) was measured by dual-energy X-ray absorptiometry (DXA).Results There was no significant difference in the incidence of LD between HAART for 1-2 years group and HAART over 5 years group (51.2％ vs 40.5％,P =0.345).The prevalence of LD was 2.4 folds with strvudine (d4T) treatment compared with zidovudine (AZT)-containing regimens (61.6％ vs 23.5％,P =0.001).Based on DXA measurements,FM of total body and limbs were significantly lower in the HAART over 5 years group than that in the control group,the untreated group and the HAART for 1-2 years group (P ＜ 0.05).Trunk FM was significantly lower in the HAART over 5 years group than the untreated group and the HAART for 1-2 years group (P ＜ 0.05).FM of total body and trunk were significantly lower in patients without LD in the HAART over 5 years group than patients without LD in the HAART for 1-2 years group (P ＜ 0.05).FM was correlated positively with body weight and BMI.Limbs FM was correlated negatively with peripheral blood triglyceride concentration.Conclusions HIV/AIDS patients with NRTIs therapy have high prevalence of LD,which mainly occurs 1-2 years after therapy,and increases with d4T treatment compared with AZT-containing regimens.There was no significant difference in the incidence of LD between the HAART for 1-2 years group and the HAART over 5 years group.FM was significantly decreased after long-term HAART in the patients with or without LD.DXA can evaluate LD objectively and guide further clinical treatment.
