Interventions of expressive writing in cancer patients are mainly implemented in foreign countries. This paper reviews the proposal and development, implementation methods and mechanisms of expressive writing, and its effect on health outcomes of cancer patients, which indicates the population sensitivity and cultural sensitivity.In recent years,more and more attention has been paid to the intermediary variables, objective index and the analysis of the writing text in order to fully explain the mechanism and identify the social psychological needs of cancer patients at different stages. Future research can focus on sensitive populations, explore intermediary variables, incorporate objective indicators, optimize intervention methods, and explore the best intervention model for localization.

A cadmium column reduction-azo dyes spectrophotometric method based on micro sequential injection lab-on-valve was established for the determination of total nitrogen in seawater. The experimental parameters were optimized, and the interference experiment was carried out. The results showed that the interference of the main components and salinity in sea water could be eliminated by using a series of standard solution prepared by national standard seawater with certain salinity. The concentration of total nitrogen in seawater was linear with the absorbance in the range of 0 . 03-1 . 00 mg/L with a correlation coefficient of 0. 9993. When determining the national standard seawater at nitrogen concentration of 0. 20 mg/L, the relative standard deviation (RSD) was 4. 9%, the detection limit was 0. 010 mg/L, and the recoveries were 99. 5%-101 . 1%. There were not significance differences between the results of this method and national standard method in the t-test analysis. The method is suitable for the determination of total nitrogen in seawater.

Objective To compare the effect of freeze-thaw tumor cells and the supernatant from tumor cell culture on the activation of lymphocytes. Methods Malignant melanoma B16 cells were prepared as tumor cell vaccine and the supernatant from tumor cell culture was collected at different time point.Transwell method was used to determine the chemotaxis of lymphocyte attracted by freeze-thaw tumor cells and the supernatant from tumnor cell culture. The cytotoxic activity of lymphocyte was detected by CCK-8 method. Results Freeze-thaw tumor cells and the supernatant from more than 2 h of tumor cell culture were found to show chemotaxis of lymphocyte. The chemotaxis of tumor cell culture more than 4 h was stronger than freeze-thaw tumor cells. Each group of chemotactic lymphocytes demonstrated to have the activity of killing tumor cells. The ability of killing tumor cells induced by the tumor cell culture more than 4 h was stronger than that induced by freeze-thaw tumor cells.In a certain range,the ability of lymphocyte chemotaxis and activation were enhanced over time. Conclusion The chemotaxis and cytotoxic activation of lymphocyte induced by the supernatant from tumor cell culture for a certain time are stronger than those by freeze-thaw tumor cells. The supernatant from tumor cell culture can be used as tumor antigen to get better immune activation instead of the freeze-thaw tumor cells.

Objective:To investigate the change of expression of miR-7 in activated CD4+ T cells in vitro, and preliminary explore its possible significance. Methods: CD4+CD62L+T cells was purified from splenocytes of FVB mice by magnetic cell sorting system (MACS). After stimulation with anti-CD3/CD28 antibody,the relative expression of miR-7 was examined by Real-time PCR, and the expression level of CD69 molecular was analyzed by FACS. Furthermore,the relative expression of miR-7 in CD4+T cells was detected at different time points during stimulation. With the treatment of ERK inhibitor PD98059,change of miR-7 expression was de-termined by Real-time PCR. Meanwhile, the proliferation of CD4+T cells was examined by CCK-8 assay and the expression level of CD69 and CD62L molecular were analyzed by FACS. Finally,the expression of cytokines IL-6,IL-10,and IFN-γ were determined by Real-time PCR. Results:Compared with control group,the relative expression of miR-7 was increased significantly after stimulation with anti-CD3/CD28 antibody,as well as expression level of CD69 molecular was augmented(P<0. 05). In contrasted with 0 h and 24 h,the expression of miR-7 was significantly increased after 48 h and 72 h during stimulation(P<0. 05). Furthermore,the relative expression of miR-7 was significantly declined in CD4+T cells in ERK inhibitor PD98059 treatment group. Finally, the expression level of CD69 molecular,as well as cytokines IL-6, IL-10 and IFN-γ, were also decreased significantly ( P<0. 05 ) . Conclusion: The relative expression of miR-7 was significantly increased in activated CD4+T cells,closely related to ERK pathway,which provided an important foundation for successive research work on exploring the functional role of miR-7 in the CD4+T cells.

Objective:To explore the relationship among supportive dyadic coping,negative emotions and ma-rital quality in middle-aged and young patients with lymphoma and their spouses.Methods:A total of 243 middle-aged and young patients with lymphoma and their spouses were selected.The Fear of Progression Questionnaire-Short Form(FoP-Q-SF)and Hospital Anxiety and Depression Scale(HADS)anxiety subscale were used to assess the negative emotions of patients and spouses,and the Dyadic Coping Inventory(DCI)and Short Marital Adjust-ment and Prediction Test(MAT)were used to evaluate supportive dyadic coping(SDC)and marital quality.Actor-partner interdependence mediation model was used to analyze the relationship among dyadic coping,negative emo-tions and marital quality.Results:The APIMeM model showed that both the FoP-Q-SF scores in patients and the anxiety scores in spouses had significant actor effects on their own supportive dyadic coping(β=-0.17,-0.29).The anxiety scores in spouses had a significant partner effect on SDC scoresin patients(β=-0.18).Both the SDC scores in patients and spouses had significant actor and partner effects on their own and their partner's MAT scores(β=1.71,1.18,1.17,1.92).The SDC scores in patients and spouses significantly mediated the relationship be-tween FoP-Q-SF scores and MAT scores in patients,with effect sizes of 46％and 13％,respectively.The SDC-scores in patients and spouses also significantly mediated the relationship between anxiety scores and MAT scoresin spouses,with effect sizes of 34％and 27％,respectively.Furthermore,the SDC scores in patients and spouses sig-nificantly mediated the relationship between FoP-Q-SF scores in patients and MAT scores in spouses,with effect si-zes of 57％and 14％,respectively.Conclusion:It suggests that supportive dyadic copingbetween spouses plays a mediating role in the relationship between negative emotions and marital quality.

Objective To elucidate the effects of SP600125 at different concentrations on the proliferation and osteo-differentiation of human adipose-derived stem cells (hASCs).Methods The hASCs harvested were cocuhured with SP600125 at concentrations of 0 μmol/L,1 μmol/L,5 μmol/L and 10 μmol/L in growth medium (OM group) and in osteogenesis medium (OM group),respectively.The DNA quantitative assay was carried out to evaluate proliferation of the hASCs;flow cytometry was used to determine the effect of SP600125 on the cell cycles of hASCs;Alkaline phosphatase level (ALP) and calcium deposition tests were conducted to observe the effects of SP600125 at different concentrations on osteogenic differentiation of the hASCs.Results The proliferation of hASCs was inhibited by 42.1％ when the cells were cocultured with SP600125 at the concentration of 10 μmol/L;the suppression decreased with decreased concentration of SP600125.The hASCs of phase G0/G1 in GM cocultured with SP600125 at the concentration of 10 μmol/L were more than those in GM cocultured with dimethylsulfoxide at the same concentration.ALP test revealed that after 10 days of culture in vitro the staining was more and more weakened and scattered and the ALP activity was more and more decreased with the increased concentration of SP600125.The extracellular calcium deposition of hASCs after 14 days of culture in vitro showed that the size and number of calcium nodules decreased with the increased concentration of SP600125.Conclusion SP600125 can suppress the proliferation and osteogenic differentiation of hASCs in vitro.
