Objective To explore the preventive and therapeutic effect of recombinant human interleukin-11(rhIL-11) on thrombocytopenia in children with non-lymphocytic leukemia after chemotherapy.Methods Sixteen children who had non-lymphocytic leukemia were divided into 2 groups by randomization,including a therapeutic group and a control group.RhIL-11[50 ?g/(kg?d)] was injected subcutaneously 24 h after chemiotherapy in the therapeutic group,and applied consecutively 10-14 days,and the control group was treated without RhIL-11.Duration of the thrombocytopenia,infusion of blood platelet,diversity of blood platelets counts and adverse effect were observed of the 2 groups.Differences between groups were examined using statistics analysis.Results There were 16 case-times(59.3%) in the therapeutic group that of could be cured without platelet transfusion,but that of control group only had 3 case-times(14.3%);the diffe-rence between 2 groups was significant(P

OBJECTIVETo investigate the clinical application of free superficial iliac circumflex artery skin flaps, as well as the management of donor site defects.

METHODS17 free superficial iliac circumflex artery skin flaps were applied for the traumatic defects or deformities on face, neck, foot, hand, ankle and lower leg, respectively. The donor site defects were closed directly or covered by paraumbilical island flaps.

RESULTSThe 17 flap size ranged from 5 cm x 3 cm to 19 cm x 14 cm. 16 flaps survived completely except 1 flap with partial necrosis, which was closed by free skin graft. The donor site defects were closed directly in 10 cases, and covered by paraumbilical island flaps in 7 flaps without no flap necrosis. The abdomen had a good appearance.

CONCLUSIONSGood appearance can be achieved with free superficial iliac circumflex artery skin flaps for the defects on face, neck, foot, hand, ankle and lower leg. Paraumbilical island flap can be used for the donor site defects.

To study the protective mechanism of Danhong injection on brain microvascular endothelial cells (rBMECs) injured by hypoxic. In the experiment, primary suckling mouse's rBMECs cells were collected and identified with factor VIII to establish the 4 h injury model. Meanwhile, rBMECs were given Danhong injection (25, 50, 100 mL . L-1), and the superoxide dismutase (SOD) activity and the malonyldialdehyde (MDA) level were detected by the biochemical method. Cell MMP-9, ICAM-1 and P53 mRNA expression levels were detected by RT-PCR method. Changes in cells' microscopic structure were observed by transmission electron microscope. According to the results, primary rBMECs were notably injured by hypoxia. Compared with model group, Danhong injection (50, 100 mL . L-1) could remarkably resist the injury induced by hypoxic, increase intracellular SOD activity, decrease MDA level and significantly down-regulate ICAM-1, MMP-9 and P53 mRNA expressions. Danhong injection (100 mL . L-1) could protect the cells' normal morphology and microscopic structure, maintain the close intercellular junction, and inhibit the hypoxia-induced cell apoptosis. The results showed that Danhong injection plays a significant role in protecting rBMECs injured by hypoxia. Its mechanism may be related to the enhancement of cells' antioxidant capacity, the inhibition of inflammatory response and the cell apoptosis.

To explore the effect and mechanism of Guhong injection against cerebral ischemia reperfusion injury, SD rats were randomly divided into the sham-operated group, the model group, the nimodipine group, and high, medium and low-dose Guhong injection groups, with 10 rats in each group. The middle cerebral artery embolization (MCAO) model was established to observe neurological deficit symptoms, infarct volume, SOD activity, MDA content, GSH-Px and CAT activity in rats, as well as the contents of t-PA, PAI, TXB2 and 6-keto-PGF1α in serum. The results showed that Guhong injection could obviously promote the recovery of neurological deficit symptoms, narrow the brain infarct volume in rats after surgery, significantlyincrease the activities of SOD, GSH-Px and CAT and decrease the content of MDA. Meanwhile, it also could obviously increase the contents of t-PA and 6-keto-PGF1α and decrease the contents of PAI and TXB2 in serum, indicating that Guhong injection have better antioxidant and antithrombus effects, as well as a significant protective effect against cerebral ischemia reperfusion injury in rats.

To study the protective effect of combined administration of active ingredients of Danhong on cultured primary mice's brain microvascular endothelial cells (rBMECs) injured by hypoxia. Primary mice's brain micro-vascular endothelial cells were cultured to establish the 4 h hypoxia model. Meanwhile, active ingredients (protocatechuic aldehyde, salvianolic acid B, hydroxysafflor yellow A and tanshinol) of Danhong were administered in rBMECs. The non-toxic dosage was determined by MTT. The leakage of lactate dehydrogenase(LDH), cell superoxide dismutase (SOD) activity and MDA level were detected by the colorimetric method. The expressions of ICAM-1, MMP-9, P53 mRNA were detected by RT-PCR method. Changes in rBMECs cell cycle and early apoptosis were detected by flow cytometry. Danhong's active ingredients and prescriptions 1, 2, 3, 7, 8, 9 could be combined to significantly restrain LDH in hypoxic cells supernatant. Prescriptions 1, 2, 3, 7, 8, 9 could significantly enhance SOD activity in anoxic cells; Prescriptions 1, 2, 3, 8, 9 could significantly decrease the MDA level; Prescriptions 1, 2, 6, 7, 9 could significantly inhibit the early rB-MECs apoptosis induced by hypoxia. After hypoxia, the up-regulated P53 mRNA expression could cause retardation in G, phase and promote cell apoptosis. This proved that the regulatory function of P53 gene lay in monitoring of calibration points in G, phase. Prescriptions 1, 2, 5, 6, 7, 8, 9 could significantly down-regulate the P53 mRNA expression; Prescriptions 1, 4, 7, 8, 9 could significantly down-regulate the ICAM-1 mRNA expression; Prescriptions 1, 3, 6, 9 could significantly down-regulate the MMP-9 mRNA expression. The combined administration of Danhong's active ingredients showed a significant protective effect on primary cultured rBMECs injury induced by hypoxia Its mechanism may be related to the enhancement of cellular antioxidant capacity and the inhibition of inflammatory response and cell apoptosis. This study could provide ideas for researching prescription compatibility, and guide the clinical medication.

OBJECTIVETo investigate the effect of education on self-evaluation and control level in patients with bronchial asthma.

METHODSSeventy-five asthmatic patients with the initial diagnosis in line with the American Thoracic Society criteria, including 46 with junior high school education or below (group A) and 29 with senior high school education or above (group B), were asked to complete a survey to assess their symptoms and asthma attacks. Asthma control test (ACT) and peak expiratory flow rate (PEFR) evaluation were performed 8, 12 and 24 weeks after salmeterol/fluticasone therapy. Step-down treatment was administered according to GINA guidelines. The self-evaluation of the patients was assessed according to ACT score, physical signs and pulmonary function. An ACT score over 19 indicate well controlled condition. The effect of education on the self-evaluation and control level of bronchial asthma was assessed.

RESULTSThe two groups had similar basal level of pulmonary function (FEV1). Eight weeks after the therapy, 29 patients in group A had ACT score over 19, including 11 with high control level; in group B, 17 had ACT score over 19, of whom 4 showed high control level. There was no significant difference between the two groups in control levels and self-evaluation (P>0.05). At 12 weeks, 37 patients in group A had ACT score over 19, with 17 having high control level; 22 patients in group B had ACT score over 19, 4 showing high control level; the two groups were similar in the control levels (P>0.05) but showed significant difference in self-evaluation (P<0.05). At the time of 24 weeks, 42 and 26 patients had ACT score over 19 in the two groups, with 19 and 5 having high control level, respectively. The two groups differed significantly in the control levels (P<0.05) and self-evaluation (P<0.05).

CONCLUSIONThe patients' education level may play a role in self-evaluation and control level of bronchial asthma, but its impact differs in the course of the treatment.
