Objective To investigate the principal indicators of self-care ability in activities of daily living for the persons with physical disability. Methods Persons with physical disability were asked to select the top 3 items out of 27 items of activities of daily living in 3 levels. Results A total of 1960 questionnaires were send out, and 1862 were returned. For all the subjects, the items related with personal hygiene, such as toileting, self-cleaning and bathing, were selected 899 times (16.1%). The items related with personal health, as visiting community clinics and community exercising, were selected 570 times (10.2%). The items related with social interaction, as making a telephone and chatting, were selected 500 times (9.0%). For the persons with physical disability of first grade, the major items most selected were eating, entertaining, self-cleaning and transferring; and self-cleaning and housework for those of second grade; self-cleaning, community activities and housework for those of third grade; and community and interaction for those of fourth grade. Conclusion The persons with physical disability mostly focused on the activities related with personal hygiene, health and social interaction, and varied with the severity of disability, from self-cleaning to housework and social participation.

OBJECTIVETo evaluate the therapeutic efficacy and side effects of oral Fructus bruceae oil combined with radiotherapy in the treatment of esophageal cancer.

METHODSA total of 80 patients with esophageal cancer were equally and randomly divided into two groups. The patients in Group A were treated with radiotherapy (60-65 Gy, 6-7 weeks) and oral Fructus bruceae oil (20 mL, 3 times per day for 12 weeks), while the patients in Group B were treated with radiotherapy alone. The short-term effect was evaluated by Response Evaluation Criteria in Solid Tumors (RECIST) and quality of life (QOL) was evaluated by the Karnofsky scoring (KFS). The outcome measures included complete remission (CR) rate, partial remission (PR) rate, effective rate as CR+PR, patients' QOL and adverse effects.

RESULTSAfter 12-week treatment, the CR and CR+PR were significantly higher in Group A than those in Group B (P <0.05). There was an improvement in esophageal obstruction of 87.5% and 60.0%, respectively, and in KFS of 84.6% and 43.9%, respectively, in Groups A and B.

CONCLUSIONOral medication with oral Fructus bruceae oil could effectively improve the efficacy of radiotherapy in esophageal cancer, including a reduction in esophageal obstruction, and also reduce the side effects of radiotherapy; thus it would be very promising for clinical application.

The relationship of HLA-A, -Cw alleles on HIV infection and AIDS disease progression in the Chinese Yi ethnic group of Sichuan province were investigated. The genetic polymorphisms of HLA-A, -Cw alleles of 102 unrelated healthy Chinese Yi ethnic individuals, 68 HIV-1 infected and 21 HIV positive long-time survivors were typed by PCR-SSP assay. Statistic signifiance was determined by the χ2 test with the SPSS software. No significant differences were observed between the HLA-A, -Cw alleles of the 68 HIV-1 infected and 102 non-infected Chinese Yi control individuals. Whereas the prevalence of A*3601,Cw*14(01-03)and Cw*0304 was significantly higher in 21 long time survivors compared with 102 healthy controls with P values of 0.016, 0.016 and 0.000 by χ2 or the Fisher exact test respectively. The result implies that A*3601,Cw*14(01-03) and Cw*0304 may be associated with slow AIDS disease progression in the Chinese Yi ethnic group, further studies on this association may yield insight on the pathogenesis of HIV-1 infection.

The 109 whole blood samples were collected from HIV-1 infected former blood donors in Henan and Shanxi. The RNA templates were extracted from plasma and used for the full gag gene amplification and sequencing. The sequences were divided into 3 groups according to sampling year. The Entropy software was used to identify the amino acids with composition difference among different groups of amino acid sequences. The results showed that there existed 8 and 13 amino acid sites with the statistical significance difference, respectively, in sequences in year 2004 and 2005, compared to those in 2002. Among them, there existed 5 amino acid sites in two groups. Of 16 amino acid sites, the increasing polymorphism and the decreasing polymorphism along the sampling year were observed in 10 and 6 amino acid sites respectively. Of 10 sites with increased polymorphism, 8 sites were located in the CTL epitopes recognized and presented by the main HLA alleles existed in Chinese population. The 6 sites with decreasing polymorphism all existed in main domains of Gag proteins.

OBJECTIVETo investigate the role of the hedgehog (HH) signaling pathway transcription factor glioma-associated oncogene hoinolog 1 (GLI-1) in EGF-regulated enhancement of the invasiveness of the prostate cancer ARCaP(E) cell line in vitro.

METHODSThe expressions of EGFR and GLI-1 in prostate cancer ARCaP(E) cells were analyzed by immunofluorescence staining. ARCaP(E) cells were treated with EGF at 100 ng/ml, followed by detection of the changes in cell morphology and invasiveness, as well as in the expressions of p-ERK, ERK and GLI-1. Migration transwell assay was used to determine the effects of 100 ng/ml EGF and GLI-1 antagonist GANT61 on the invasiveness of the ARCaP(E) cells.

RESULTSBoth EGFR and GLI-1 were expressed in the ARCaP(E) cells. EGF induced morphological transition of epithelial-like ARCaP(E) cells to mesenchymal-like cells, increased their in vitro invasiveness, and significantly upregulated the expressions of p-ERK and GLI-1 in the ARCaP(E) cells (P<0.05). GANT61 significantly inhibited the in vitro invasiveness of the ARCaP(E) cells and reduced the enhancing effect of EGF on their invasiveness (P<0.05).

CONCLUSIONThe results from ARCaP(E) cells shed light on the cross-talk of the HH pathway with the EGF/ERK signaling pathway. GLI-1 might be responsible for EGF-regulated enhancement of the invasiveness of ARCaP(E) cells in vitro.

OBJECTIVETo investigate the effect of glucocorticoid on the expression levels of osteoprotegerin (OPG) and receptor activator of nuclear factor kappa B ligand (RANKL) mRNAs in rat femoral head and the antagonistic effect of Epimedium, and explore the mechanism of Epimedium in preventing glucocorticoid-induced femoral head necrosis.

METHODSForty-eight adult SD rats were randomized into glucocorticoid group, Epimedium group and control group. In the former two groups, the rats received intramuscular injection of 12.5 mg prednisolone twice a week, and in Epimedium group, additional 1 ml/100 g aqueous Epimedium extract (equivalent to 0.1 g/ml of the crude drug) was administered intragastrically once daily. The control group received only intramuscular saline injection. After 4 weeks of treatment, osteonecrosis of the left femoral head was detected by HE staining, and the right femoral head was sampled for detection of OPG and RANKL mRNA expressions using real-time quantitative PCR.

RESULTSIn glucocorticoid, Epimedium and control groups, the mortality rate of the rats was 12.5% (2/16), 6.25% (1/16), 0 (0/16), and femoral head necrosis occurred at a rate of 71.43% (10/14), 26.67% (4/15), and 0 (0/16), respectively. In glucocorticoid group, the expression level of OPG mRNA was significantly lower, RANKL expression significantly higher, and OPG/RANKL ratio significantly lower than those in Epimedium and control groups (P<0.05). OPG, RANKL and their ratios showed no significant differences between Epimedium group and the control group.

CONCLUSIONEpimedium can prevent glucocorticoid-induced femoral head necrosis probably by antagonizing glucocorticiod-induced abnormal expressions of OPG and RANKL mRNA.

This study was aimed to investigate clinical and prognostic significances of 4 target antigens (CD19, CD20, CD22 and CD33) for antibody-based immunotherapy and to evaluate the applications of these antibody-based target therapy to adult acute lymphoblastic leukemia (ALL). The immunophenotype of 220 adult patients with ALL were analyzed by four-color flow Cytometry, and cytogenetic and molecular parameters were detected by conventional cytogenetics, fluorescence in situ hybridization, real-time quantitative PCR, nested PCR and DNA sequencing. The results showed that CD19 positive (CD19(+)) cases were more in female (46.4% vs. 23.4%, P = 0.006), elderly patients aged > 60 years (14.4% vs. 2.1%, P = 0.022), CD33(+) co-expression cases (47.8% vs. 12.0%, P = 0.001) and genetic high-risk group (55.8% vs. 20.8%, P = 0.002) compared with CD19 negative (CD19(-)) cases; CD20(+) cases had lower co-expression of CD13 than CD20(-) cases (31.6% vs.67.1%, P = 0.000) and no significant prognostic indications for CD20(+) was observed; CD22(+) cases had higher relapse rate at 12-month than CD22(-) cases (93.9% vs.57.1%, P = 0.041) in B-ALL patients; CD33(+) cases had higher incidence of Ph(+) than CD33(-) cases (43.5% vs.19.4%, P = 0.007) and significantly correlated with Ph(+) (r = 0.261, P = 0.006). It is concluded that elucidation of the characteristics of the target antigens (CD19, CD20, CD22, CD33) used for antibody-based immunotherapy will help hematologists making the correct decision whether and when to use these antibody-based target therapies.
