Objective To explore the levels and the significance of IL-11 and soluble glycoprotein 130(sgp130) in the treatment of new-diagnosed acute leukemia(AL) during the induced remission. Methods The levels of IL-11 and sgpl30 in 47 patients with acute leukemia were determined by ELISA respectively before treatment and after completed remission(CR), and the number of white blood cell (WBC) and platelet (Plt) were valued by hametometry. Results Plasma IL-11 level of AL patients was significantly lower than normal (P ＜0.05), and increased obviously to the normal level when complete remission was achieved. And it correlated with PLT counts. While sgp130 level was higher than normal (P＜0.05),and declined after CR and correlated with WBC counts. Conclusion The plasma IL-11 and sgp130 levels can be helpful for confirming the diagnosis,evaluating the efficiency and predicting the prognosis of AL.

OBJECTIVEThis study aimed to observe the postoperative pain rate and degree of pain in preschool children with cleft lip and palate, and investigate the effect of nursing intervention on pain relief.

METHODSA total of 120 hospitalized cases of three- to seven-year-old preschool children with cleft lip and palate were selected from May to October 2011. The subjects were randomly divided into the control group and experimental groups 1, 2, and 3. The control group used conventional nursing methods, experimental group 1 used analgesic drug treatment, experimental group 2 used psychological nursing interventions, and experimental group 3 used both psychological nursing intervention and analgesic drug treatment. After 6, 12, 24, and 48 h, pain self-assessment, pain parent-assessment, and pain nurse-assessment were calculated for the four groups using the pain assessment forms, and their ratings were compared.

RESULTSThe postoperative pain rates of the four groups ranged from 50.0% to 73.3%. The difference among the four groups was statistically significant (P < 0.001). The differences among the control group and experimental groups 1 and 2 were not statistically significant (P = 0.871), whereas the differences among experimental group 3 and the other groups were statistically significant (P < 0.001).

CONCLUSIONPostoperative pain in preschool children with cleft lip and palate is common. Psychological nursing intervention with analgesic treatment is effective in relieving postoperative pain.

OBJECTIVEThis study investigated the role and mechanism of calcineurin (CaN)-nuclear factor of activated T cells (NFAT) pathway in the myoblast apoptosis induced by cyclic tensile strain.

METHODSMyoblasts were cultured using an in vitro-mechanical stimulation model and imposed with tension for different hours with a multi-channel cell stress loading system. Cyclosporine (CsA) was used as CaN inhibitor to clarify the role of CaN in the apoptosis induced by cyclic stress. Hochest 33258 staining and flow cytometry detection were performed to detect the apoptotic cells. Real-time polymerase chain reaction was conducted to detect the mRNA expression of CaN and NFAT. Protein levels of NFAT3 were evaluated by Western blot.

RESULTSThe apoptosis rate increased with the extension of loading time. The mRNA expression of the CaN subunits, CnA and CnB, and the protein levels of NFAT3 also increased. When the myoblasts were incubated with CsA, the apoptosis rate decreased, the mRNA expression of CnA and NFAT3 significantly decreased, and the NFAT3 protein expression levels became significantly lower than those of the groups without CsA.

CONCLUSIONContinuous cyclic tensile stress can induce myoblast apoptosis. The CaN-NFAT signaling pathway may be involved in the cyclic stretch-induced apoptosis of myoblasts.

OBJECTIVE:To establish the HPLC fingerprint of Zhibai dihuang pills(concentrated pills),and to evaluate its quality. METHODS:The determination was performed on Dikma Diamonsil C18column with mobile phase consisted of 0.1%acetic acid solution-methanol(gradient elution)at the flow rate of 1.0 mL/min. The detection wavelength was set at 260 nm,and column temperature was 30 ℃. The sample size was 10 μL. Using paeonol as reference,HPLC chromatograms of samples from A, B,C manufacturers within validity period and samples from manufacturer A within validity period and out of validity period were drawn. The similarity of HPLC chromatogram for samples from A,B and C manufacturers and samples from A manufacturer within validity period and out of validity period was evaluated by TCM Chromatogram Fingerprint Similarity Evaluation System (2004 A). Common peaks of HPLC chromatogram for 3 manufacturers sample within validity period were confirmed. RESULTS:There were 24,29 and 32 common peaks in HPLC chromatograms for each 10 batches of samples from manufacturer A,B and C within validity period,respectively. The similarity of corresponding HPLC chromatograms of samples from manufacturer A,B and C compared with control HPLC chromatography were all higher than 0.94 with good agreement. HPLC chromatograms of sample from A manufacturer within validity period had good agreement with that from A manufacturer out of validity period. CONCLUSIONS:Established HPLC fingerprint analysis method can represent the quality of Zhibai dihuang pills (concentrated pills),but cannot effectively identify the expired samples.

The plasmodium of Physarum polycephalum is a suitable eukaryotic cell for cell cycle investigation, but there is no compatible transient expression system for the plasmodium. Using the promoter and terminator of ardC actin of Physarum polycephalum substituted the CMV IE and SV40 polyA of plasmid pDsRedl-N1, using cassette PardC-MCS-DsRed1-TardC substituted the cassette PardC-hph-TardC of plasmid pTB38, we constructed plasmids pXM1 and pXM2 for transient expression of red fluorescent protein (RFP) in Physarum polycephalum respectively. After reconstituting the transcription elongation factor homologous gene (pelf1) of Physarum polycephalum into the pXM2, we generated a plasmid pXM2-pelf1. After the plasmid pXM1, pXM2 and pXM2-pelf1 were electroporated into the plasmodium of Physarum polycephalum, we observed optimum RFP and PELF1-RFP expression under fluoroscope and confocal microscope between 24-48 h after electroporation, and found that ELF1-RFP expression was accumulated in nucleus of microplasmodium, the optimum electroporation parameters were 40 V/cm electric field, 1 ampere current, and 70 micros electric shock time. The results suggest that this expression system is qualified for transient expression of specific protein in plasmodium of Physarum polycephalum.

Objective: To study the specific killing effect of CD4 membrane protein targeted chimeric antigen receptor modified T (CAR-T) cell. Methods: The second generation CD4 targeted chimeric antigen receptor containing 4-1BB costimulation domain was insert into lentiviral vector through recombinant DNA technology. Lentivirus was prepared and packaged by 293T cells with four plasmids. Beads activated T cells were transduced with lentivirus and the transduction efficiency was checked with Protein L and flow cytometry. T cell subsets and IFN-γ concentrations were detected with probe-tagged antibody and cytometric bead assay. Results: ①The transduction efficiency of activated T cells with prepared lentivirus were 50.0%-70.0%. A subset of CD8⁺ T cell acquired dim expression of CD4 membrane protein after activation. CD4⁺T cell and CD8⁺CD4^dim T cell were gradually killed by CD4 targeted CAR-T post lentivirus transduction. ②The kill efficacy of CD4 targeted CAR-T cell and control T cell toward KARPAS 299 T cell at an E∶T ratio of 8∶1 for 24 h was (96.9±2.1)% and (11.2±3.1)%, CAR-T cell has a higher killing efficacy than control T cell (t=7.137, P=0.028). The IFN-γ concentrations in culture supernatant of CAR-T cell with K562-CD4 cell, CAR-T cell with K562 cell and CAR-T cell alone were (15 648±2 168), (1 978±354) and (1 785±268) pg/ml, CAR-T cell cocultured with K562-CD4 cell produced more IFN-γ than the other two controls (P<0.01). Conclusions CD4 targeted CAR-T has an immunophenotype of CD8⁺CD4^-T cell. CD4 targeted CAR-T cell has killing efficacy toward normal CD4⁺T cell and CD4⁺T lymphoma cell. CD4 targeted CAR-T cell also has a killing efficacy toward CD4^dim target cell.
