Objective To probe the effect of motivational interviewing(MI) on the caregiving burden and coping style of continuous renal replacement therapy (CRRT) nurses.Methods A total of 60 CRRT nurses were divided into intervention group (30 cases) and control group (30 cases) by random digits table method.The intervention group was given MI measures and the control group was used humane care measures, 6 months later, the differences of the caregiving burden and coping style were compared between the two groups.Results The caregiving burden's level after the intervention of two groups' nurses dropped, the level in the intervention group was lower than that in the control group: (42.02±3.57) points vs.(56.35±4.71) points, and there was significant difference, t=13.280, P＜0.05.The positive coping style of two groups CRRT nurses was enhanced and the negative coping style was weakened.The positive coping style's level in the intervention group was higher than that in the control group and the negative coping style's level was lower than that in the control group:(16.56±4.78) points vs.(13.81±1.09) points, (7.73±0.28) points vs.(9.83±0.96) points, the all differences were statistically significant, t=3.071, 11.502, P＜0.05.The positive coping style in the intervention group CRRT nurses with their caregiving burden was negatively correlated, r=-0.424, P＜ 0.01, but whose negative coping style with their caregiving burden was positively correlated, r=0.282, P＜ 0.05.Conclusions MI is more conductive to reduce the CRRT nurses' caregiving burden, change their way of coping, so that the CRRT nurses will put in greater enthusiasm to work.

Hematopoietic stem cell transplantation(HSCT) is one of the measures therapy on acute leukemia in children.Very-high-risk children with acute lymphocytic leukemia (ALL),such as Philadelphia chromosome-positive(Ph+),T cell immunophenotype,achieved the first complete remission(CR1),and then receive allogeneic HSCT(allo-HSCT).The transplantation group had significantly improved disease-free survival(DFS)and overall survival(OS) compared with chemotherapy group. ALL children in the second complete remission(CR2) were recommended to receive allo-HSCT,especially early-relapse group. All children in the third complete remission (CR3) were recommended to receive an allo-HSCT,and reduce replapse rate through inducing graft versus leukemia.Total body irradiation-based conditioning regimens in children with ALL has advantage over chemotherapy conditioning regimens.Children with acute myeloblastic leukemia (AML) achieved CR1 and then undergo all-HSCT.This group had significantly improved DFS and OS compared with chemotherapy group.The children with relapsed AML,if having suitable donor,were recommended to receive allo-HSCT. The children with AML who underwent transplantation relapse,and can receive the second transplantation.There was no advantage in children patients with AML using TBI-based conditioning regimens.Conditioning regimens consisted of high-dose cytarabine,in combination with granulocyte colony-stimulating factor has advantage,and improve DFS. Unrelated umbilical cord blood has emerged as a potential option.Compared with unrelated bone marrow transplantation,there was no different in DFS and relapse.For the extent,it is one of the donor hematopoietic stem cell sources.

OBJECTIVE:To observe therapeutic efficacy and safety of cinobufacini capsules combined with paclitaxel and cisplatin in the treatment of middle and advanced cervical cancer.METHODS:A total of 92 patients with middle and advanced cervical cancer were randomly divided into observation group (46 cases) and control group (46 cases).Both groups received pelvic intensity-modulated radiotherapy (IMRT)+interstitial brachytherapy.Control group was additionally given Paclitaxel injection 135 mg/m2,d1+Cisplatin injection 75 mg/m2,d1,21 d as a treatment course,and received chemotherapy for 2 cycles since the fnrst day of radiotherapy.Observation group was additionally given Cinobufacini capsules 0.5 g orally since the first day of radiotherapy,3 times a day,until the end of radiotherapy.Clinical efficacies as well as platelet count,KPS score,body weight,pain relief and the recovery of platelet abnormality were observed in 2 groups,and the occurrence of toxic reaction was recorded.RESULTS:The complete remission rate,the rate of platelet count abnormality recovery as well as remission rate and total remission rate of pain after 3 weeks of treatment in observation group were significantly higher than control group,with statistical significance (P＜0.05).There was no statistical significance in the total response rate and remission rate after 4,5 weeks of treatment between 2 groups (P＞0.05).After treatment,platelet count of 2 groups were significantly lower than before,and the observation group was significantly lower than the control group;KPS score of 2 groups and body weight of observation group were significantly higher than before treatment;body weight of control group was significantly lower than before,and the observation group was significantly higher than the control group,with statistical significance (P＜0.05).The incidence of grade Ⅲ-Ⅳ neutropenia,nausea and vomiting,grade Ⅰ-Ⅱ diarrhea in observation group were significantly lower than control group,with statistical significance (P＜0.05).CONCLUSIONS:Based on conventional treatment,cinobufacini capsules combined with paclitaxel and cisplatin show significantly therapeutic efficacy for middle and advanced cervical cancer,improve blood hypercoagulation and survival quality,relieve pain and reduce the occurrence of toxic reaction.

Objective To observe the effects of limited fluid resuscitation (LFR) on immune function and inflammatory mediators in patients with multiple bone fracturescomplicated with traumatic hemorrhagic shock. Methods One hundred and two patients with multiple bone fractures complicated with traumatic hemorrhagic shock admitted to the Affiliated Hospital of Medical College of Ningbo University from January 2014 to June 2016 were enrolled, and they were divided into a LFR group and a early sufficient routine fluid resuscitation (RFR) group by random number table, each group 51 cases. After admission, the patients in the two groups underwent bandaging and hemostasis at the traumatic sites and preoperative management was prepared. The patients in RFR group were treated with early sufficient RFR, while LFR group was treated with LFR. The changes of hematocrit (HCT), blood platelet count (PLT), prothrombin time (PT), blood lactic acid and immune cells, inflammatory mediators and micro RNA-155 (miR-155) were observed in patients of the two groups at 4 hours after resuscitation.Results Compared with RFR group, the resuscitation time (hours: 3.67±1.45 vs. 5.14±1.61), levels of PT (s: 11.43±2.21 vs. 15.73±2.52), serum lactic acid (mmol/L: 3.35±0.15 vs. 3.81±0.25), tumour necrosis factor-α [TNF-α (ng/L): 14.10±3.39 vs. 16.28±3.47], interleukin [IL-10 (ng/L): 31.43±10.51 vs. 40.09±13.23, IL-6 (ng/L): 490.10±55.13 vs. 610.30±63.15] and endothelin-1 [ET-1 (pg/L): 183.35±30.51 vs. 250.01±31.23] in LFR group were significantly decreased (allP < 0.01), while PLT (×109/L: 134.58±28.13 vs. 108.12±30.35), HCT (×10-2: 0.34±0.04 vs. 0.24±0.05), miR-155 (0.15±0.02 vs. 0.08±0.02) and CD4+CD25+ regulatory T cell [CD4+CD25+Treg (×10-2): 2.28±0.47 vs. 2.10±0.39] in LFR group were obviously increased (allP < 0.01).Conclusions Using LFR in the emergency treatment of patients with multiple bone fractures complicated with traumatic hemorrhagic shock can effectively shorten the resuscitation time, regulate the patients' coagulation function, reduce the unnecessary excessive liquid infusion, improve immune status and decrease the degree of inflammatory reaction.

Objective To observe the effects of oxaliplatin on proliferation in human hepatoma cell lines QGY in vitro and investigate the mechanism. To provide the theory foundation whether it can be used for the chemotherapy of hepatocellular carcinoma. Methods The inhibition of proliferation in QGY cell was estimated by MTT-test. Morphologic changes were observed under light microscope and electronic microscope. Distribution of cell cycle and apoptosis was analyzed using flow cytometry. The expression of cell cycle protein and apoptosis-associated gene protein was detected with immunohistochemical technique. Results Oxaliplatin could inhibit the proliferation of QGY cells and the inhibition depended on the exposure time and dose. The cells showed morphologic changes at the early stage of apoptosis under the light microscope: the shrunk and round cells, condensed cytoplasma and pycnosis nucleus. Apoptotic cells and apoptotic body could be found under the transmission electronic microscope. The analysis of cell cycle indicated that oxaliplatin blocked cells at S and G_2/M phases and the cells of G_0/G_1 phase reduced. When treated with oxaliplatin for 72 h, the expression of cyclin A and Bax were up-regulated, mutant type P53, Bcl-2 and Myc down-regulated, and Fas was not changed. Conclusion Oxaliplatin could inhibit proliferation of the hepatoma cell lines. Cell cycle blocked at S and G_2/M phase. The apoptosis were related to the up-regulation of Bax and down-regulation of mutant type P53, Bcl-2 and Myc. It could not induce apoptosis through the Fas approach.

Objective To study the effect of transfection with antisense DNMT3b gene eukaryotic expression plasmid on the growth of human cholangiocarcinoma cell line QBC939,and to explore the role of DNMT3b in the cholangiocarcinoma tumorigenesis.Methods The constructed antisense DNMT3b gene eukaryotic expression plasmid was transfected into QBC939 cells using liposome.The expression level of DNMT3b protein was detected by Western blot after stable transfection.The growth curves of transfected cells and un-transfected cells were observed by MTT method respectively.The cell proliferation ability was also observed by the test of colony formation in soft agar.The alterations of the cell cycle and the apoptosis rate were detected by FCM.Results Following the transfection,the protein level of DNMT3b decreased significantly;transfection with antisense DNMT3b gene eukaryotic expression plasmid did not affect the cell growth curve of QBC939,and did not decrease the cell colony formation rate(P=0.717);transfection with antisense DNMT3b gene also did not result in cell cycle alterations or induce cell apoptosis(P=0.089).Conclusions Transfection with antisense DNMT3b gene eukaryotic expression plasmid can down-regulate the expression level of DNMT3b in QBC939.It can not affect the growth and proliferation of human cholangiocarcinoma cell line QBC939,nor alter the cell cycle and induce cell apoptosis.

AIM To study the effect of neferine on intracellular adriamycin(ADM) accumulation in MCF-7/Adr cell line. METHODS The cytotoxic effect was determined by MTT assay. The intracellular ADM concentration was assayed by HPLC. RESULTS Neferine(Nef) decreased the IC 50 of ADM to MCF-7/Adr cells but increased the intracellular concentration of ADM. CONCLUSION The mechanism of the MDR reversal effect of Nef is associated with the increase of the intracellular accumulation of anticancer drug.

OBJECTIVE:To observe the stimulating effect of instilled sodium ozagrel for injection on rabbits'auricular vein.METHODS:Rabbits'auricular veins were assigned to receive sodium ozagrel for injection(19.0 mL?kg~(-1))or 5% glucose injection(19.0 mL?kg~(-1))q.d for 7 days by instillation.The rabbits were executed at 24 h and 72 h respectively after the last infusion,with rabbits'auricular blood vessel samples taken at the distance of 1 cm and 5 cm distal from injection site for histopathologic examination.RESULTS:Histopathologically,the rabbits treated by sodium ozagrel for injection(19.0 mL?kg~(-1))or 5%glucose injection showed similar changes in the skin and veins of the injection sites,and there were no abnormalities such as congestion,edema,induration and necrosis in both groups.CONCLUSION:No obvious stimulating effect on rabbits'auricular vein blood vessel was noted for sodium ozagrel for injection.

Objective To investigate the expression of bradykinin as a substrate of CD26/DPP Ⅳ in rats with ischemia/reperfusion injury following lung transplantation (LTx). Methods Thirty-six syngeneic male SD rats were randomly allocated into control group and experimental group (n= 18each), and 36 rats served as donors. In control group and experimental group, the lungs were flushperfused and preserved with LPD and LPD+ CD26/DPP TV catalytic inhibitor (AB192) respectively,and LTx was performed 18 h after cold ischemia Histopathological studies were also done on the same locus of lung specimens and staining for bradykinin. The different proteins were separated by means of immobilized PH gradient-based two-dimensional gel electrophoresis. The differential expression of bradykinin was compared by Western blotting. Results The expression of bradykinin in control group was significantly higher than in experimental group. As compared with experimental group,bradykinin expression was significantly up-regulated in control group (P <0 . 05 ). Conclusion Inhibitor of CD26/DDP Ⅳ enzymatic activity significantly ameliorated ischemia/reperfusion injury in the early stage after LTx, which is probably associated with inhibition of the protein expression of bradykinin.
