In the present work we measured the concentration of Interleukin 1(IL-l) in the supernatant of cultured macrophage by the amount of ~3H-thymidine incoporated into T cells. The concentration of IL-1 was found to be marketly increased when macrophages were cultured with LPS (10?g/ml), SiO_2(100?g/ml), C.Parvum(1mg/mouse) Comparing the effects of these three stimulants on the incease of IL-1 from macrophage SiO_2 appeared to be the strongest one and C.P. and LPS were found to have cooperation for this increase in IL-1. Matrine,at the concentration of 100?g/ml, was found to antagonize the effect of LPS on theactivation of macrophage.

Objective:To investigate the relationship between narcissism and entrepreneurial intention and roles of achievement motive and risk aversion in college students.Methods:In this study,375 college students were selected from Henan University.Their narcissism,entrepreneurial intention,achievement motive and risk aversion were assessed with the Narcissism Scale,Entrepreneurial Intentions,The Achievement Motive Scale,and General Risk Aversion Scale.Results:The scores of overt narcissism positively predicted the scores of entrepreneurial intention (3 =0.37,P ＜ 0.001),the predictive effect of covert narcissism on entrepreneurial intention was not significant (β =-0.05,P ＞ 0.05).The scores of achievement motive partly mediated the relationship between the scores of overt narcissism and entrepreneurial intention (95％ CI:0.06-0.22),and this mediation effect was moderated by the scores of risk aversion (β =0.09,P ＜ 0.05).Only when the score of risk aversion was higher (above one standard deviation),achievement motive was a mediator between narcissism and entrepreneurial intention.When the score of risk aversion was lower,the mediate effect was not valid.Therefore,the moderated mediation model was confirmed.Conclusion:It suggest that the moderated mediation model is feasible,that is,achievement motive is a mediator between narcissism and entrepreneurial intention,but this mediation is moderated by risk aversion.

Objective Through studying change of serum level of IL-10 in patients of severe trauma with haemorrhagic shock,to investigate effect of severe trauma with haemorrhagic shock bypass on anti-infiammatory reaction in patients.Methods Menbers of experimental group are 43 patients of Severe trauma(ISS scope≥16).43 patients scheduled for attending with haemorrhagic shock are divided into simple severe trauma group(group B)and severe trauma with haemorrhagic shock(group C);and healthy control group(group A)is made up of randomly seleeted 20 healthy people of medical examination.Blood samples for cytokines and organ function were collected from the vetn of menbers of experimental group(B and C)with limosis at the following time:that day of injury,(T1),3th (T2),5th(T3),and 14th(T4)day after injury;blood samples of healthy control group(A)with limosis were collected at that day of examination;serum level of IL-10 was measured by radioimmunoassay.Results In experimental group(B and C),the serum peak level of IL-10 emerged on T3 and then stepped down;the serum peak level of them increased abviously compared with group A(P＜0.05 or P＜0.01).Furthermore,the serum level of them in C group was usually higher than that on the same time in group B.Conclusion It was longer and severer in time and degree that effects of severe trauma with haemorrhagic shock bypass on IL-10 of body compared with that of simple severe trauma.

Objective:Entrepreneurial failure refers to the process of entrepreneurial performance continuous decline until the business is bankrupt. The aim of this research is to analyze implicit stigma effect against entrepre-neurial failure in college students. Methods:Sixty-four college students in a natural class participated in this survey, 4 D values of the total tool of entrepreneurial failure implicit stigma and its three dimensions (including cognitive appraisal,emotional reaction,and behavior tendency)were assessed with the traditional implicit association test (IAT). Through independent sample t test,the differences between zero and 4 D values were analyzed. The differ-ences of four D values at gender and entrepreneurial experienceon were explored,the difference between reaction time of the compatibility task and incompatibility task was analyzed,and the reliability of the tool of implicit stigma effect against entrepreneurial failure was evaluated. Results:The 4 D values were all greater than zero. In 3 inde-pendent dimensions and total IATs,the automatic association between entrepreneurial failure and negative words was closer relative to positive words (P<0. 001 ),it showed that their implicit negative attitude against entrepre-neurial failure was significant. Split-halfreliability and internal consistency coefficient of the total tool of entrepre-neurial failure implicit stigma were respectively 0. 87 and 0. 82. Conclusion:In this study,the entrepreneurial failure implicit stigma effect may be significant in college students. These college studeuts have implicit negative cognition and emotion,and discrimination behavior tendency against entrepreneurial failure.

Objective:To develop the Abusive Behavior Scale for Superiors under the Chinese context (ABSSC) and test its validity and reliability.Methods:Based on literature analysis and the open questionnaire survey in 32 employees,this study defined the construct of ASBSS,and compiled the preliminary questionnaire.A sample of 200 employees coming from companies was selected for item analysis.A sample of 445 employees was investigated with this questionnaire,223 of them were assessed for exploratory factor analysis and 222 of them were assessed for confirmatory factor analysis and internal consistency test with 2 week interval.Results:The ABSSC consisted of 11 items in 3 factors,which were neglect and slander,obstructionism and hard on subordinates.The 3 factors explained 55.45％ of the total variance.Furthermore,the result of CFA indicated that the model fitted the data with well constmct validity (RMSEA =0.06,GFI =0.94,NFI =0.92,CFI =0.96,IFI =0.96).The Cronbach α coefficient of the whole scale and its three facts were 0.87,0.79,0.78,and 0.76,respectively.Conclusion:It suggests that the Abusive Behavior Scale for superiors under the Chinese context (ABSSC) is reliable and valid enough to be applicable to measure superiors' abusive behavior under the background of Chinese culture.

T4 cells were isolated twice separately from peripheral blood of the same donor.After activation by lectin,the isolated cells were culturedwith the medium containing self-made IL-2 for a long period.The culturedcells were identified for OKT antigens by immuno-fluorescent technique onday 10 and 22 of the cultivation,and the appearance of both T4 and T8antigens on the same cell (double marker cell)could be detected in about60-80%of cultured cells.The double marker T cells decreased in numberand the percentage of single marker T cells,either T4 or T8 cells,increasedgradually along with the cultivation.The function of double marker T cellswere investigated and the suppressor activity of these cells on PWM indu-ced antibody production response by cooperation between B cells and fresh T4cells was found.These results suggest that human peripheral blood T4 andT8 cells are not terminaly differentiated cells,because T4 and T8 antigencan be coexpressed on the same cell during the earlier cultivation.Afterlong period of activation,T4 and T8 double marker cells may change intoeitherT4 or T8 cells.

OBJECTIVE:To observe the therapeutic efficacy of active immunization combined with dydrogesterone in the treatment of recurrent abortion,and its effects on serum levels of leptin(LP)and adiponectin(ADPN). METHODS:Totally 103 patients with recurrent abortion from department of gyhecology,Jinan Third People's Hospital during Nov. 2015 to Nov. 2016 were selected as trial group,and then divided into trial group one(n＝51)and trial group two(n＝52)according to admission order. Other 100 normal pregnant women were taken as control group. Trial group one was given active immunization combined with dydrogesterone,including that lymphocytes from the patients'spouse were injected subcutaneously into the patient,every half a month,3 times of active immunization as a course of treatment,and was given Dydrogesterone tablet 10 mg after pregnancy,bid, until 3 months after the pregnancy. Trial group two was given Dydrogesterone tablet 10 mg,bid,until 3 months after the pregnancy. The serum levels of β-HCG,LP and ADPN were compared between trial group and control group at admission,the serum levels of β-HCG,LP,ADPN and pregnancy outcome(recurrent abortion,full-term pregnancy and successful delivery rate) was compared between 2 trial groups after treatment. RESULTS:At admission,the serum levels of β-HCG,LP and ADPN in trial group were significantly lower than control group. After treatment,the levels of β-HCG,LP and ADPN,successful delivery rate and full-term pregnancy rate in trial group one were significantly higher than trial group two, recurrent abortion rate was significantly lower than trial group two,with statistical significance(P＜0.05). No adverse reactions were observed in the study. CONCLUSIONS:The use of active immunization combined with dydrogesterone can significantly improve the serum levels of LP and ADPN as well as pregnancy outcome,with good safety.

Objective:To explore the main characteristics of college students' entrepreneurial failure fear, and the mediating effect on the relationship between optimism and entrepreneurial intention among college students. Methods: Totally 427 college students were selected. Their optimism trait, entrepreneurial failure fear and entrepreneurial intention were accessed with the Optimism-pessimism Scale (OS), Failure Fear Scale (FFS) and Individual Entrepreneurial Intention Scale IEIS). Results: The average FFS score in college students was (2.8 ± 0.6). The scores of decrease of social value were higher in males than in females (P ＜0.01). The scores of decrease of self-esteem were higher in students from rural than those from cities (P ＜ 0.05). The total FFS scores were lower in freshmen than in sophomores, juniors and seniors (P ＜0.01). OS scores positively predicted IEIS scores (β =0.19, P ＜0.001), and FFS scores partially mediated the relationship between the scores of OS and IEIS (effect size = 0.11, 95％ CI:0.04-0.19). Conclusion: This study shows significant gender, birthplace and grade differences in college students' entrepreneurial failure fear. Entrepreneurial failure fear maybe partially mediate the relationship between optimism pessimism and entrepreneurial intention.

Objective To explore the relationship among serum vitamin D,calcium ion,blood lipid lev-els and preeclampsia in pregnant women,and analyze the pregnancy outcomes of pregnant women with pre-eclampsia.Methods A total of 166 pregnant women with preeclampsia who underwent pregnancy examina-tion and delivered in Urumqi Municipal Maternal and Child Health Care Hospital from January 1,2021 to Jan-uary 1,2023 were selected as the observation group,and 200 healthy pregnant women during the same period were selected as the control group.The levels of serum vitamin D,calcium ion,phosphorus ion,blood lipid in-dicators,uric acid,and creatinine were detected in the two groups,and the pregnancy complications and preg-nancy outcomes were observed.The influencing factors of preeclampsia were analyzed by using multivariate logistic regression model.Results The levels of serum vitamin D,calcium ion,and high density lipoprotein in the observation group were lower than those in the control group,and the levels of serum uric acid and creati-nine were higher than those in the control group,with statistical significance(P＜0.05).The incidence of fetal growth retardation,placental abruption,oligohydramnios,cesarean section,low birth weight infants,premature delivery,and postpartum hemorrhage in the observation group were significantly higher than those in the con-trol group(P＜0.05).Multivariate logistic regression analysis showed that serum vitamin D(OR=15.141,95％CI:1.831-125.204,P=0.012),calcium ion(OR=4.625,95％CI:2.654-8.059,P＜0.001),high-den-sit y lipoprotein(OR=0.395,95％CI:0.235-0.666,P＜0.001),creatinine(OR=1.034,95％CI:1.005-1.063,P=0.020)and uric acid(OR=1.006,95％CI:1.003-1.010,P＜0.001)were independent factors for the occurrence of preeclampsia in pregnant women.Conclusion The levels of serum vitamin D,calcium ions,blood lipids,uric acid and creatinine may be correlated with the occurrence of preeclampsia.
