Objective To explore the nursing effect evaluation of vacuum sealing drainage based latissimus dorsi bridge free skin flap to repair refractory wound. Methods Thirty-seven cases of patients with intractable wounds were chosen as the observe group from January 2009 to January 2012, and 26 cases accepting the traditional way of wound care with intractable wounds were selected as control group from January 2006 to December 2008. Control group adopt conventional methods wound and the observation group accepted VSD accessories line wound negative pressure closed drainage before the wound phase 2 latissimus dorsi bridge free skin flap repairment. After treatment, the dressing time, interval and dressing change, the time of hospitalization were observed, and the nursing effect were compared after skin flap to repair for 8 days and 16 days between patients of two groups. Results The dressing time and hospitalization days in observation group after treatment were significantly less than that in control group ( <0.05), the number of dressing have significantly shortened compared with control group ( <0.01), and the dressing change interval in control group had significantly difference ( <0.01) . The effect of 2 patients in control group after skin flap to repair was poorer, but the observation group did not appear significant necrosis. Compared the good rate of two groups, the observation group patients was significantly higher than control group ( <0.01) . The therapy good rate of observation group was significantly better than that of control group (<0.01) . Conclusion The negative pressure closed drainage based ascending latissimus dorsi bridge free skin flap repairment has contributed to cure the refractory wound recovery significantly.

AIM: To explore the different inhibitory effect of arsenic trioxide (As_2O_3) on hepatocarcinoma cell growth in SMMC-7721 and BEL-7402 cell lines and its mechanism. METHODS: The cell culture and trypan blue staining were used to study the inhibitory effect of arsenic trioxide on cell growth, and the glutathione (GSH) contents in hepatocarcinoma cells treated with arsenic trioxide were detected. RESULTS: Arsenic trioxide inhibited the growth of BEL-7402 cells in a time and dose-dependent manner. The inhibitory effect was significant at a lower dose of 0.50 ?mol/L for 24 h, however, to SMMC-7721 cells, a higher dose of 2.00 ?mol/L for 96 h was needed. The inhibitory rate of arsenic trioxide (0.25-2.00 ?mol/L) on BEL-7402 cell growth was higher than that on SMMC-7721 cells. The content of GSH in SMMC-7721 cells was much higher than that in BEL-7402 cells [(50.8?5.2) (?mol/g) protein and (18.7?1.4) ?mol/g protein, respectively]. CONCLUSION: There was a significant difference in inhibition of hepatocarcinoma cell growth by arsenic trioxide between BEL-7402 and SMMC-7721 cell lines, the cause of which may be due to the difference in GSH content in BEL-7402 and SMMC-7721 cells.

BACKGROUND: The existence of minimal residual leukemia cells is the main cause for the recurrence of acute leukemia in children, and immunological biological therapy has attracted more and more attentions in the various methods from eliminating minimal residual disease. Previous studies have found that interferon α-2b can effectively inhibit the increase of tumor cells in vivo in children with neuroblastoma and malignant lymphoma, whether it can inhibit the increase of leukemia cells?OBJECTIVE: To investigate the effects of interferon α-2b in vitro on leukemia cells.DESIGN: A comparative observation taking human promyelocytic leukemia HL-60 cell line as the material.SETTING: Cell Culture Room; Immunological Laboratory; Cell Room, Institute of Pediatrics, Affiliated Hospital,Medical College of Qingdao University.MATERIALS: HL-60 cell line was provided by Shandong Institute of Basic Medical Sciences. Interferon α-2b was purchased from Megagene Company Fluorescein isothiocyanate (FTTC) rabbit-anti-rat Ig solution (CatEK001) and CD13 anti-human monoclonal antibody solution (Cat. DK013Y) were purchased from Union Stem Cell & Gene Engineering Co.,Ltd.METHODS: The experiments were carried out in the Institute of Pediatrics, Affiliated Hospital, Medical College of Qingdao University from March to September 2005. HL-60 cells culture system was established in vitro, and the oncentration was adjusted to 1×109 L-1. The cells were divided into control group and experimental group. In the experimental group, each well was added by interferon-α-2b with the terminal concentration of 5×105, 1×106, 2×106,5×106 and 1×107 U/L, respectively. In the control group, each well was added by saline of the same volume. The cells were cultured continuously for 48 hours. The morphological changes of HL-60 cells were observed using Wright's staining under light microscope; Cell apoptosis was observed using acridine orange/ethidium bromide double staining; Antigen expression and maturation and differentiation on cell membrane were observed by determining CD13 protein expression; Proliferation and activity of HL-60 were detected with methyl-thiazol-tetrazolium (MTT) assay.MAIN OUTCOME MEASURES: The occurrence of apoptosis was judged according to the uniformity and staining of HL-60 nuclear chromatin; HL-60 cell proliferation was judged according to the absorbance (A) value; The maturation of HL-60 cells was judged according to the number of positive CD13 cells.RESULTS: ① HL-60 cell apoptosis: The cells were cultured for 48 hours. When the concentration of interferon α-2b was 5×105 U/L, there were mainly early apoptotic HL-60 cells; When the concentration was 1×107 U/L, there were mainly late apoptotic cells, and the apoptotic rate was significantly higher than those in the control group (P < 0.01 ).② HL-60 cell proliferation: The A values in the experimental groups treated with interferon α-2b of 2×106 U/L and 1 ×107 U/L were significantly lower than that in the control group (P < 0.01). ③ Maturation of HL-60 cells: The percentages of positive CD13 cells in the experimental groups treated with interferon α-2b of 1 ×106 and 1 ×107 U/L were significantly lower than that in the control group (P < 0.01).CONCLUSION: It is concluded that interferon α-2b can enhance the apoptosis, inhibit the proliferation and promote maturation and differentiation of HL-60 cells.

Objective To explore the associations between microsatellites in gonadal receptor genes and dysfunctional attitudes in adolescent with major depressive disorder(MDD).Methods Polymerase chain reaction(PCR),capillary electrophoresis and genetic scanning were performed in testing the length of microsatellites in first-onset adolescent depressive patients.Dysfunctional attitudes scale(DAS) was used in rating the dysfunctional cognition of adolescent depressive sample.These results were tested by correlative analysis and comparison analysis.Results 1.There existed significantly negative correlation between microsatellite′s length in estrogen receptor ?(ER?) gene and total score of DAS in female adolescent patients with first-onset depressive disorder.2.DAS′ total score of shorter alleles′ group was significantly higher than that of longer alleles′ group on female′ estrogen receptor ?(ER?) Gene.Conclusion The microsatellite′s length of ER? and ER? gene may have associations with dysfunctional attitudes of female adolescent with MDD.
