Objective:To investigate clinicopathological features and prognosis of transformed mycosis fungoides (TMF) .Methods:A retrospective analysis was performed on clinicopathological data collected from 24 patients with TMF, as well as on flow cytometry results of 16 peripheral blood samples obtained from 11 of the 24 patients, who visited Hospital of Dermatology, Chinese Academy of Medical Sciences between 2014 and 2020.Results:Among the 24 patients, 11 were males and 13 were females. Their average age at diagnosis of TMF was 50.0 years (range: 18 - 77 years), and patients with early-stage TMF (9 cases) and tumor-stage TMF (15 cases) were aged 44.8 and 52.6 years on average, respectively. The average time interval from diagnosis of MF to large cell transformation was 3.7 years, and 8 patients were diagnosed with TMF at the initial visit. Histopathologically, large cells infiltrated in a diffuse pattern in 20 cases, as well as in a multifocal pattern in 4, and the proportion of large cells in 7 cases was greater than 75%. Immunohistochemically, 18 patients showed positive staining for CD30, and the proportion of CD30-positive large cells was greater than 75% in 9; negative staining for CD30 was observed in 6. Flow cytometry of 16 peripheral blood samples showed the presence of cell subsets expressing clonal T cell receptor (TCR) -vβ in 2 of 4 patients with early-stage TMF and 10 of 12 with tumor-stage TMF, and tumor cells with higher forward scatter than normal lymphocytes were detected in 16 samples. During the follow-up, among the patients with early-stage TMF, 3 progressed to tumor-stage TMF 3.3 years on average after large cell transformation, 1 progressed to erythrodermic MF in stage IIIA, and the other 4 still showed an indolent course; among the patients with tumor-stage TMF, 1 progressed to stage-IV TMF, and 5 died 3.3 (1.5 - 6) years after large cell transformation.Conclusion:Large cell transformation may occur in patients with MF in any stage, some patients have poor prognosis, so close follow-up is needed for patients with TMF.

Hepatocellular carcinoma (HCC) is a common malignant tumor with poor prognosis and high mortality. In this study, we demonstrated a novel vaccine targeting HCC and tumor neovascular endothelial cells by fusing recombinant MHCC97H cells expressing porcine α-1,3-galactose epitopes (αGal) and endorphin extracellular domains (END) with dendritic cells (DCs) from healthy volunteers. END⁺/Gal⁺-MHCC97H/DC fusion cells induced cytotoxic T lymphocytes (CTLs) and secretion of interferon-gamma (IFN-γ). CTLs targeted cells expressing αGal and END and tumor angiogenesis. The fused cell vaccine can effectively inhibit tumor growth and prolong the survival time of human hepatoma mice, indicating the high clinical potential of this new cell based vaccine.

Objective:To explore the mediating effect of positive emotion on relationship between cognition reappraisal and meaning of life in freshmen.Methods:Totally 192 freshmen[62 males and 130 females,aged 18 to 22 years,mean age (20 ± 2) years] were assessed with the Chinese version of the Emotion Regulation Questionnaire (ERQ),Positive words of the Positive and Negative Affect Scale (PANAS) and Chinese version of the Meaning of Life Questionnaire (MLQ).Interval of 3 months of longitudinal data was used to investigate the mediating role of positive emotions in cognitive reappraisal sense and meaning of life.Results:The EPQ scores were positively correlated with the scores of PA,MLQ-P,and MLQ-S(r =0.17-0.26,Ps ＜ 0.05).The PA scores were positively correlated with the scores of MLQ-P and MLQ-S (r =0.16-0.35,Ps ＜0.05).Bootstrap test showed that positive emotions mediated meaning of life through cognitive reappraisal (95％ CI:0.065-0.295).The structural equation model proved to exhibit an appropriate data fit (x2/df=1.58,RMSEA =0.06,CFI =0.98,GFI =0.95).Conclusion:It indicates that cognitive reappraisal is related to meaning of life and positive emotions,and positive emotions mediate the relationship between cognitive reappraisal and meaning of life among freshmen.

Objective:T explore the longitudinal mediation of emotional labor and emotion regulation between occupational stress and job burnout in cinema employees.Methods:This study was a two-point longitudinal study (Interval of 2 months) with the 1067 employees from 44 city cinemas across the country as the sample,using the Emotional Labor Questionnaire (ELQ) to measure the degree of emotional labor,Emotion Regulation Questionnaire (ERQ) to measure the degree of emotion regulation,Occupational Stress Indicator-2(OSI-2) to measure the degree of occupational stress,Maslach Burnout Inventory(MBI) to measure the degree of job burnout and Job Satisfaction Scale to measure the degree of job satisfaction.A series of structural equation model analyses was conducted for data analyses.Results:The scores of expression suppression were negatively correlated with scores of occupational stress (r =-0.16,P ＜0.01),and positively correlated with the scores of job satisfaction (r =0.17,P ＜0.01).The structural equation model which include the scores of occupational stress as the predictive variable,the scores of emotional labor and emotion regulation as the mediator,the scores of job burnout and job satisfaction as the outcome variable fit well.Emotional labor (surface acting and deep acting) acted as a mediator between occupational stress and job burnout(95 ％ CI:0.03-0.05;0.02-0.05).Emotion regulation (cognitive reappraisal) acted as a mediator between occupational stress and job bumout(95％ CI:0.01-0.03).Conclusion:Emotional labor and emotion regulation acted as a mediator between occupational stress and occupational outcomes.Expression suppression has positive effect in Chinese culture.People who well in using cognitive reappraisal can lead to positive work effect througgh more deep acting and less surface acting.

Objective To estimate the expression of ER and PR in the endometrium of both intrauterine adhesions (IUA) and non-IUA specimens. Methods The endometrium specimens from patients undergoing hysteroscopy for confirmed moderate IUA (n=20: 10 in proliferative phase, and 10 in secretory phase) were enrolled as the IUA group in Beijing Obstetrics and Gynecology Hospital from October 2014 to August 2015. The specimens scheduled for hysteroscopy due to infertility were recruited into the control group (n=26: 13 in proliferative phase, and 13 in secretory phase). Immunohistochemistry and quantificational real-time PCR (qRT-PCR) were used to detect the expression of ER-α, ER-β and PR in endometrium with different menstrual period in both groups. Results (1) Location: in both groups, the expression of ER-α, ER-β and PR appeared in the endometrial glandular epithelial cells and the stromal cells of the endometrium. The positive brown granules of ER-α, ER-β and PR appeared mainly in cell nucleus. (2) ER-α and ER-β in the endometrium:the protein expression of ER-α and ER-β in IUA group (proliferative phase: 0.657 ± 0.028, 0.493 ± 0.023; secretory phase: 0.537 ± 0.020, 0.365 ± 0.031) were significantly higher than those of control group (proliferative phase: 0.586 ± 0.025, 0.437 ± 0.022; secretory phase:0.459 ± 0.025, 0.323 ± 0.017;all P<0.01). And the ER-αand ER-βmRNA expressions in IUA group were 2.524 ± 0.296, 1.947 ± 0.339, higher than those of control group in the proliferative phase (all P<0.01), and in the secretory phase (1.977±0.333, 1.345±0.292) were also higher than those in the control group (all P<0.01). (3) PR in the endometrium: the protein expression of PR was not significantly different between IUA group (proliferative phase:0.248±0.025, secretory phase:0.194±0.024) and control group (proliferative phase: 0.234 ± 0.019, secretory phase: 0.186 ± 0.020; P=0.162, 0.359). Meanwhile, there were no statistical differences in the mRNA expression of PR in both groups with different menstrual period (proliferative phase: 1.144 ± 0.384 versus 0.981 ± 0.306, secretory phase: 0.763 ± 0.237 versus 0.631 ± 0.203; P=0.270, 0.166). (4) ER and PR expression in menstrual cycles: the expression of ER-α, ER-β and PR in the IUA group changed with the menstrual cycles, and their expression in the proliferative phase were higher than those in the secretory phase (all P<0.05). Conclusions The expression of ER-α and ER-β in the endometrium of IUA patients changes with menstrual cycle, and are higher compared with those in normal endometrium. No difference is found in the PR expression between the two groups.

Purpose To investigate the expression and significance of ArhGAP29 and E-cadherin in endometrial tissue of intrauterine adhesions (IUAs) and to explore their roles in the pathogenesis of IUAs.Methods The expression of ArhGAP29 and E-cadherin was detected by immunohistochemical PV 9000 two-step method.The correlation between ArhGAP29 and E-cadherin expression and clinical features was analyzed.Results (1) The immunoreactive score (IRS) of ArhGAP29 and E-cadherin in normal endometrial tissue were higher than those in IUAs endometrial tissue (P =0.017,P =0.004).(2) IRS of ArhGAP 29 and E-cadherin in moderate IUAs patients were higher than that in severe IUAs patients (P =0.020,P =0.026).In IUAs patients without amenorrhea,the IRS of ArhGAP29 and Ecadherin were higher (P =0.019,P =0.031) than that in IUAs patients with amenorrhea.(3) The decrease of ArhGAP29 expression had a significantly parallel relationship with the negative expression of E-cadherin (r =0.725,P ＜ 0.001).Conclusion The expression of ArhGAP29 and E-cadherin decreases in endometrial tissue of IUAs patients,which is related with degree of IUAs severity.ArhGAP29 and E-cadherin may participate in the IUAs formation.

Objective Intrauterine adhesions cause serious damage to women′s reproductive health, to establish animal dis?ease mode, pure mechanical damage is the most similar cause to human pathogenesis, that is very necessary to conduct prospective studies. The study aimed to investigate the efficiency and significance of different mechanical damage methods to establish intrauterine adhesions model in rats. Methods 45 female SD rats were randomly( random number table) divided into three groups:pure scratch group (n=15), 2 mm diameter curet was used to scrape endometrial tissue; Incision?suture group (n=15), a longitudinal incision was made in the uterus, a blade was used to scrape endometrial tissue, the incision was then sutured with absorbable thread;Control group ( n=15) , sham operation, then the abdomen was closed after exposed to air for 20 minutes, the uterus were not injured. Endometri?al keratin immunohistochemical staining, Intrauterine AFS score, fi?brosis semi?quantitative score and pregnancy outcomes were observed to compare the injury of the two methods in establishing the model. Results ( 1) The degree of endometrial glandular epithelium keratin staining decreased significantly in both pure scratch and incision?su?ture groups compared to the control group. (2) AFS scores in pure scratch group and incision?suture group[3.0 (2.0-3.8), 5.0 (3.8-8.0)] were higher than control group[0 (0-0)], the difference was statistically significant (P<0.017); Incision?suture group was higher than pure scratch group, but the difference was not statistically significant(P>0.017). Endometrial fibrosis semi?quantitative scores in pure scratch group and incision?suture group[5.0 (4.0-5.3), 6.5 (5.8-8.0)] were higher than control group[0 (0-0)], the difference was statistically significant ( P<0.017);Incision?suture group was higher than pure scratch group, but the difference was not statistically significant (P>0.017). (3) Embryo number in pure scratch and incision?suture group side [0.5 (0-3.3), 0 (0-2.3)] was lower than the normal side [7.6 (6.8-8.0), 8.0 (7.8-9.0)],the difference was statistically significant (P<0.05) Conclusion Pure mechanical damage including pure scratch and incision?suture method to establish IUAs model were feasible. Both of the two methods could help to do research about pathogenesis and pathophysiological mechanisms of IUAs. Incision?suture method maybe can cause heavier fibrosis degree.

Objective:To investigate the effect of search for meaning on depression and the moderating role of perspective change in college students. Methods:The participants were 1 16 college students. The hypotheses were tested by analyzing data collected at 3 time points. Search for meaning and the presence of meaning in life were measured with the Meaning in Life Questionnaire,the dimension of perspective change in Meaning-Focused Coping Questionnaire was used to assess the ability to change perspective,and depression was assessed with the Center for Epidemiological Studies Depression Scale (CES-D). Results:The scores of perspective change was positively corre-lated with scores of meaning in life (r=0. 29 ,P<0. 0 1 ),and negatively correlated with CES-D scores (r=-0. 34,P<0. 001). The scores of perspective change moderated the relationship between scores of search for mean-ing and scores of presence of meaning in life (β=0. 22,P<0. 01 ),and this interaction effected CES-D scores through the mediation of scores of presence of meaning in life. That is,for the individuals with lower perspectivechange score (blow one standard),the score of search for meaning was negatively associated with the presence of meaning in life,with in turn increased CES-D scores,95%CI:0. 07 -033;among the individuals with higher per-spective change scores (above one standard),there was no mediation effect. Conclusion:The results suggest that perspective change could moderate the relationship between search for meaning and meaning in life,which in turn buffers depression. The findings imply the potential positive role of perspective change in the process of searching for meaning in life among university students.

Objective: The purpose of this research is to investigate the relationship between computer game addiction,a subtype of internet addiction,and parental Rearing styles.Methods: Using Computer Game Addiction Inventory(CGAI) and EMBU,we investigate a sample of 747 senior high school students in Beijing.According to whether participants' sum score of five dimensions of CGAI is larger than 1.5 SD,we divide them into two groups: tendency to addiction and non-tendency to addiction.Then we analyze the data with methods of MANOVA and Canonical Correlation.Results: There is significant difference in sex distributing between tendency to addiction and non-tendency to addiction.There is also significant difference in parental rearing styles between two groups.Under authoritarian rearing styles,children score higher on nearly every dimension of CGAI.Conclusion: Boys are more likely to get addicted to computer games than girls.Negative parental rearing styles associate closely with computer game addiction.
