Follicular lymphoma (FL) is a subtype of B cell lymphoma,which derived from follicular germinal center.As the most common type of indolent lymphoma,the overall prognosis of FL is good.However,the prognosis of FL is heterogeneous.With the application of rituximab,the therapeutic effect and the prognosis of the disease is further improved.For the relapsed / refractory patients,especially who have received first-line chemotherapy with rituximab in the early,transplantation is an important choice.Compared with the previous conventional myeloablative conditioning regimen,reduced-intensity conditioning (RIC) effectively reduced the non-relapse mortality (NRM),extended the allogeneic transplantation recipients,but the high rate of relapse after transplantation is the main defect.The application of donor lymphocyte infusion after transplantation therapy not only can reduce the recurrence rate but also treat the disease relapse.In the future,the improvement of transplantation strategy and the application of new drugs may bring new ideas and opportunities for FL therapy.

Objective To detect the expression of macrophage inlfammatory protein 1α(MIP-1α) in the myocardium of viral myocarditis (VMC) mice at different phases. Methods A total of 120 4-week-old male BALB/c mice were randomly divided into 2 groups, 80 in the VMC group and 40 in the control group. Mice in VMC group were inoculated intraperitoneally with coxsackievirus B3 to build VMC models, while mice in control group were treated with DMEM cultivate liquid. Ten mice of each group were sacriifced on days 3, 7, 15 and 30 after treatment and their heart tissues were collected for analysis. The level of MIP-1αin the myocardium was determined by immunohistochemistry. Myocardial histopathology was examined with hematoxylin and eosin stain. In addition, the relationship between the level of MIP-1αand the degree of myocardial lesion was investigated. Results The expression of myocardial MIP-1αprotein in VMC group was up-regulated in myocardium on day 3 after inoculation of virus, and slowly decreased after the peak on day 7, but still sustained a high level on day 30. Compared with the control group, the levels of MIP-1αin VMC group were increased signiifcantly at every phase (P<0.05). Furthermore, positive correlation was found between MIP-1αprotein expression levels and myocardial histopathologic scores in VMC group (r=0.94, P<0.01). Conclusion The up-regulated expression of MIP-1αmay play a critical role in the pathogenic mechanisms of viral myocarditis.

ObjectiveTo investigate the effects of task-driven teaching mode on physical therapy teaching in higher vocational education. Methods40 students in 2006 rehabilitation class were taught with routine mode as the control group, while 35 students in 2007 rehabilitation class taught with task-driven mode and routine mode as experimental group. ResultsAt the end of the course, the results of examination in theory and practice were better in the experimental group than control group (P<0.01). 85.71%～94.28% students in the experimental group said that the task-driven teaching mode could improve their comprehensive quality especially the skill of practice, as well as the interest and ability of learning. ConclusionTask-driven teaching mode can improve the teaching effect on physical therapy, and received by most of the students.

Objective To investigate the inoculum effect of fosfomycin on enterococci,in comparison with penicillin,rifampin,vancomycin and teicoplanin.Methods A total of 91 strains of enterococci were obtained from the patients hospitalized in The First Affiliated Hospital of China Medical University from January 2010 to January 2012.There was no repeated strain.The 91 strains consisted of 44 Enterococcus faecalis and 47 Enterococcus faecium strains.Agar dilution method was used to measure the minimum inhibitory concentrations (MIC) of the five antibiotics against the 91 enterococci strains under standard low inoculation concentration (1 × 105 colony-forming units [cfu]/mL) and high inoculation concentration (1 × 107 cfu/mL).Results For all tested strains,MIC of fosfomycin fluctuated between 16-64 tμg/mL in high and low inoculated concentrations.Among the tested strains,both Enterococcus faecalis and Enterococcus faecium had the highest drug-sensitive rate (100.0％) and the lowest drugresistance rate (0) to fosfomycin.With the increase of the inoculation concentration,MIC of the five antibiotics increased less than 8 times,which indicated that there was no inoculation effect.Conclusion Fosfomycin shows high drug-sensitivity against enterococci without inoculum effect in vitro,and it is recommended for the treatment of enterococci-infected patients.

To understand the pyrolysis mechanism of lignin with α-O-4 linkage, 4-(3-hydroxy-1-phenoxypropyl)-phenol was selected as an α-O-4 type lignin dimer model compound, and its pyrolysis process was studied by density functional theory with M06-2X method at 6-31+G (d,p) level. Equilibrium geometries of the reactant, intermediates, transition states and products were fully optimized. The activation energies in each pyrolysis pathway were calculated. The dimer decomposed mainly through the homolytic cleavage and concerted decomposition of the C(α)-O linkage. Pyrolytic products mainly included various phenolic compounds such as phenol, 4-methylphenol, 4-vinylphenol and p-coumaryl alcohol, as well as light compounds such as ethanol, methanol and formaldehyde. Pyrolytic depolymerization process has its potential in biomass-based fuels.

Objective To investigate the role of Stathmin in pancreatic cancer invasion and metastasis and its relationship with DNA methylation. Methods Immunohistochemical detection of MBDI and Stathmin protein expression in 40 cases of pancreatic cancer and 15 cases ot normal pancreatic tissue were performed,followed by analysis of their clinical and pathological relationship with pancreatic cancer; Human pancreatic cancer cell line BxPC-3 was treated with 5-Aza-2-dC (AZA).Both qRT-PCR and Western blot analysis of Stathmin expression were used before and after AZA treatment; Stathmin-siRNA transfected BxPC-3 cells were divided into the Stathmi-siRNA group and the empty vector control group.Transwell chamber invasion assay and animal experiment were performed to measure the changes in cell invasion and metastatic capability. Results lmmunohistochemistry showed positive MBDI and Stathmin expressions in 28 (70％) and 24 (60％) out of 40 cases of pancreatic cancer,respectively,which were significantly higher than that in the normal pancreatic tissue (P＜ 0.05); MBDI and Stathmin protein expressions were positively correlated (r =0.356,P =0.037),so were MBDI expression and lymph node metastasis (P=0.023).Stathmin expression was significantly correlated with clinical staging and lymph node metastasis (P =0.002,and P =0.001,respectively).After AZA treatment,both Stathmin mRNA and protein expression in BxPC-3 were significantly decreased.Transwell chamber invasion assay showed that compared with the control group,the cell invasion capability of the Stathmin-siRNA group was significantly decreased (P＜0.05).Animal experiment showed that the incidence of liver metastasis was significantly lower in the Stathmin-siRNA transfected group than the empty vector control group (P＜0.05).Conclusion Demethylation may contribute to the reduction of Stathmin expression in pancreatic cancer and further improve the prognosis of pancreatic cancer patients.

AIM: To discuss the mechanism of action of Zhiyu Granules on treating diabetic peripheral neuritis. METHODS: The model of diabetic peripheral neuritis in mice was induced by streptozotocin.The effect of Zhiyu Granules on the contents of sciatic nerve inositol in model mice through ELSD(evaporative light scattering detector) was examined,and the activity of Na~+-K~+ pump in sciatic nerve was measured,and the activity of SOD and the contents of MDA in erythrocytes were detected,and the ultrastructures of sciatic nerve,pancreas and kidney in model mice were observed by electric microscope. RESULTS: Zhiyu Granules could increase the contents of sciatic nerve inositol in model rats,and enhance the activity of Na~+-K~+ pump,and improve the ultrastructures of sciatic nerve and pancreas cell.Zhiyu Granules couldn't improve the ultrastructure of renal corpuscles,or affect the activity of SOD and the contents of MDA in erythrocytes of model mice yet. CONCLUSION: Zhiyu Granules is effective in clinical treatment of diabetic peripheral neuritis.
