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 investigate the effects of CYP3A5~* 3 genetic polymorphism on analgesia with fentanyl. Methods One hundred and eighty ASA Ⅰ or Ⅱ patients, aged 20-50 yr, Hart nationality, Henan province, scheduled for elective abdominal total hysterectomy or myomectomy under general anesthesia, were enrolled in this study. The polymorphic sites of the CYP3A5~* 3 allele were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The patients were assigned to one of 3 groups according to their genotypes: wild homozygote group, mutation heterozygote group and mutation homozygote group. Midazolam, remifentanyl, propofol and succinylcholine were used for induction of anesthesia. The patients were mechanically ventilated after tracheal intubation. Remifentanyl, propofol and atracurium were given iv for maintenance of anesthesia. The pain was assessed with visual analog scale (VAS) after consciousness was regained. When VAS score > 3, the patients were given fentanyl 20 μg every 5 min until VAS score was decreased to ≤3 and then patient-controlled intravenous analgesia (PCIA) with fentanyl was started. The background infusion rate of fentanyl 1.0 mg and droperidol 5 mg (in 100 ml normal saline) was 0.5 ml/h. The PCIA pump was programmed to give a 2 ml bolus of fentanyl solution with a 5 min lockout interval, 7 time successful delivery per hour and maximum dosage 145 μg/h, and VAS score was maintained less than 3. The amount of fentanyl used within 24 h after surgery was recorded. Results No significant difference was detected in the fentanyl consumption in the 24 h during PCIA among the 3 groups (P> 0.05). Conclusion The genetic polymorphism CYP3 A5~* 3 is not the factor contributing to the individual variation in the patient's response to analgesia with fentanyl.

AIM:To explore the effect of recombinamt rat CC16 protein (rCC16) on LPS-induced expression of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and IL-8 in the rat tracheal epithelial (RTE) cells. METHODS:The RTE cells were incubated with rCC16 at concentrations of 0.5, 1.0 and 2.0 mg/L in serum-free media for 2 h prior to LPS (0.1 mg/L) treatment for further 24 h.The cells were harvested for assessing the mRNA levels of TNF-α, IL-6 and IL-8 by RT-qPCR.The cell culture supernatants were collected for analyzing the protein levels of TNF -α, IL-6 and IL-8 by ELISA.In addition, the nuclear translocation of nuclear factor-κB (NF-κB) p65 was tested by Western blot.RESULTS:rCC16 inhibited LPS-induced IL-6 and IL-8 expression at both mRNA and protein levels in the RTE cells in a concentration-dependent (0~2 mg/L) manner, as demonstrated by RT-qPCR and ELISA.However, no concentra-tion-dependent manner between the dose of rCC 16 and TNF-αexpression was observed , and rCC16 inhibited LPS-induced TNF-αexpression at lower concentration (0.5 mg/L).rCC16 concentration-dependently inhibited the effects of LPS on the level of nuclear translocation of NF-κB p65.CONCLUSION:rCC16 suppresses LPS-mediated TNF-α, IL-6 and IL-8 pro-duction through inactivation of NF-κB activity in RTE cells .
