Objective: To investigate the influence of social comparison and social support on negative physical self of female from adolescents to young adulthood. Methods: 980 female students aged from 12 to 22 completed NPSS-F (negative physical self scale-fatness), MSPSS (multidimensional scale of perceived social support) and PACS (physical appearance comparison scale). Their body mass index (BMI) was also calculated by weight and height of the subjects. Results: High school students had higher score in Fatness dimension than middle school students (13.5?9.3/11.0?9.0,P

Objective To study the expressions of MIF,CD68 and CD57 which are the markers of macrophages,macrophage migration inhibition factors and natural killer cells in ovarian cancer tissues and their significances. Methods Immunohistochemistry staining was used to detect the expressions of MIF,CD68 and CD57 in 56 ovarian cancer tissues and 5 normal ovary tissues. Results MIF,CD68 and CD57 had positive expressions in ovarian cancer tissues at different degrees,but the expressions of MIF,CD68 and CD57 were week or negative in normal ovary tissues.Furthermore,the positive expression levels of MIF,CD68 and CD57 in ovarian cancer tissues were increased with the grade of ovarian cancer.The expression of CD57 was lower than the expression of CD68 in ovarian cancer(P

ObjectiveTo evaluate clinical significance of serum free light chains (sFLC) in diagnosis and response to the therapies of patients with multiple myeloma (MM).MethodssFLC (κ,λ and κ / λ ratio)were examed by immumoassay from 62 patients with MM at different stage. The results were analyzed associated with clinical data,and 35 cases of chronic renal failure(CRF)patients and 62 cases of healthy donors were taken as controls.ResultsMedium sFLC of normal κ value was (13.25±6.46) mg/L,λ value was (18.39±11.42) mg/L; and κ / λ ratio was (0.97±0.64) mg/L (range 0.33-1.61).sFLC κ and λ of CRF patients were (200.01±299.87) mg/L,(191.02±245.98) mg/L,significantly higher than that of the normal control group (t =-17.804,-16.894,both P ＜ 0.001),but the κ/λ ratio was at normal range (1.11±0.29).κ value range was at 16.20- 35 250 mg/L in newly diagnosed intact immunoglobulin MM patients with IgGκ,IgAκ and IgDκ type.The range of λ values was 15.70-4885 mg/L in IgGλ,IgAλ,IgDλ type,and κ/λ ratio was abnormal in 96.5 ％ (55/57) patients (＜0.5 or ＞1.5).The κ,λ value and κ/λ ratio were close to that of the normal after remmision.ConclusionsFLC ( κ,λ,and κ / λ ratio) are very good monitoring markers for MM.

Background and purpose:Nir1 is a transmembrane receptor for chemokine (C-C motif) ligand 18. CCL18 speciifcally binds to Nir1 at the cellular membrane of breast cancer cells to exert its invasion and metastasis. However, the speciifc mechanism of Nir1 is not clear in glioma. This study probed the effect and mechanism of Nir1 in the invasion of glioma cells.Methods:Western blot was used to detect the expression of Nir1 in glioma cells. siRNA plasmid was used to transfect U251 cells. Western blot was used to analyze the expression of Nir1 and protein phosphorylation of Akt in the cells transfected by Nir1 plasmid.In vitro Matrigel invasion assay was used to detect the invasive ability in the cells that were transfected. F-actin polymerization assay was used to detect F-actin recognition ability in cells.Results:The expression of Nir1 was higher in all glioma cells. After transfection, the invasion of siNir1/U251 was obviously decreased than the SCR/U251, F-actin content was reduced compared to the control group. Akt phosphorylation experiment result showed that the protein phosphorylation of Akt was enhanced in control group cells CCL18 following stimulation. However, the existence of CCL18 would affect the phosphorylation of Akt in siNir1/U251.Conclusion:Nir1 is high expression in glioma cells, and Nir1 binding to chemokine CCL18 promotes glioma cells invasion and metastasis through regulation the phosphorylation of Akt and F-actin polymerization .

Anti-Sj?gren's syndrome type A（SSA) and anti-Sj?gren's syndrome type B（SSB) antibodies both belong to the antinuclear antibody spectrum and are common in patients with systemic lupus erythematosus, Sj?gren's syndrome and undifferentiated connective tissue disease as well as asymptomatic patients. Approximately 1% of pregnant women are positive for anti-SSA and anti-SSB antibodies and only 1%-3% of the fetuses carried by primiparae with anti-SSA and anti-SSB antibodies show immune-mediated cardiac conduction and structural abnormalities. Due to its low incidence and insidious onset, some pregnant women were diagnosed positive for antibodies against SSA and SSB for the first time only due to fetal heart block or structural abnormalities during pregnancy. Domestic and international research on the effects of anti-SSA and anti-SSB antibodies on fetal heart and the prenatal monitoring, diagnosis, intrauterine treatment and prognosis of fetal cardiac abnormalities related to anti-SSA and anti-SSB exposure are reviewed to guide the clinical work of obstetrics.

Objective: To investigate the prevalence and associated factors of eczema in children in order provide reference for the prevention and treatment of eczema. Methods: Two primary schools in a district of Shenyang were randomly selected to conduct a questionnaire survey on 2 240 students in May 2017. Children with eczema need to be diagnosed by a doctor. Results: There were 838 cases of eczema with a reported rate of 37.4%, 38.7% in boys and 36.1% in girls. The age of 6 to 12 months was the peak period of first eczema in children, and the proportion of eczema within 1 year was up to about 70%. Children who have had eczema in the past were now more likely to catch a cold, and the reported rates of allergic rhinitis, asthma and food allergies were also significantly higher. The Logistic regression analysis showed that the mother was unhappy during pregnancy(OR=1.32,95%CI=1.03-1.69), the parents were more educated (OR=1.60, 95%CI=1.19-2.16), and the parents were allergic (OR=1.58,95%CI=1.07-2.33；OR=1.41, 95%CI=1.02-1.94), family history of diabetes(OR=1.95, 95%CI=1.41-2.68), and cesarean(OR=1.33, 95%CI=1.07-1.65) were risk factors of eczema in children. Conclusion The incidence of children eczema is affected by maternal mood during pregnancy, family factors and delivery mode. It is of practical significance to prevent children eczema in early development for reducing the incidence of other allergic diseases in the future.

Objective: To investigate the affecting factors of type 1 diabetes mellitus(T1DM) in children, and to provide reference for the prevention and treatment measures in the future. Methods: A case-control study was carried out among 106 children diagnosed with T1DM in a hospital in Shenyang. At the same time, 106 healthy children were selected as the control group by 1∶1 matching of age, gender and living area. The early life-related factors that may affect the development of T1DM in two groups were investigated by questionnaire. Results: The average age of diagnosis in 106 cases with T1DM was(8.02±3.49) years, girls accounted for 60.4% and boys 39.6%. Multi-factor Logistic regression analysis showed that high family socioeconomic status and higher education of fathers were associated with lower odds of development of T1DM. Family member smoking(OR=2.51, 95%CI=1.19-5.29), family history of diabetes(OR=2.56, 95%CI=1.18-5.55), maternal obesity(OR=5.42, 95%CI=2.49-11.83) and infection during pregnancy(OR=3.45, 95%CI=1.04-11.46) were associated with higher risk of T1DM(P<0.05). Conclusion The occurrence of T1DM in children is affected by many factors including heredity, maternal health during pregnancy and family economy,highlighting the importance of early life prevention of T1DM.

Objective:To report two cases of post-transplantation lymphoproliferative disorders (PTLD) after kidney transplantation in children and review the literature, and to improve clinicians' understanding of PTLD in children.Methods:The clinical data of two children with PTLD admitted to the Children's Hospital of Fudan University were collected and analyzed. The PTLD-related literature of PubMed, Embase, Web of Science, Scopus, Cochrane Library, Wanfang, CNKI, Weipu Database and China Biomedical Literature Service System from the establishment of the database to January 2020 were collected for literature review. Multivariate logistic regression analysis method was used to analyze the influencing factors of prognostic in children with PTLD.Results:Both of the patients had negative Epstein-Barr virus (EBV) and Cytomegalovirus (CMV) before transplantation and anti-thymocyte immunoglobulin (ATG) were induced during transplantation. PTLD in case 1 and case 2 was diagnosed at 3 and 12 months after transplantation, respectively, with positive EBV and CMV serological reaction. The pathological diagnosis was monomorphic PTLD in case 1 and the case 2 was clinically considered as non-hodgkin lymphoma. They all received thrapies of immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. PTLD was relieved and graft function was normal in 2 cases, while case 1 died two and half years after transplantation due to intracranial fungal infection. According to the analysis of 56 children (including 2 cases in this study) with PTLD from the literature review, the median time of PTLD from transplantation was 41.8 months. The initial involved organs were digestive tract [17 cases (30.4%)], respiratory system [8 cases (14.3%)], nervous system [7 cases (12.5%)] and pharyngeal lymph ring [7 cases (12.5%)], respectively. The main pathologic type of PTLD was monomorphic [34 cases (60.8%)]. Fifty-six cases were all positive in EBV serological reaction when PTLD was diagnosed. The treatment included immunosuppressive reduction combined with anti-CD20 monoclonal antibody and chemotherapy. Forty-eight cases of PTLD were relieved, while 8 cases lost graft function. Eleven cases died, including 3 cases due to infection and the other 8 cases due to PTLD. Multivariate logistic regression showed that monomorphic PTLD was a risk factor of death for PTLD children ( OR=21.616, 95% CI 1.007-464.107, P=0.049). Conclusions:PTLD in children with kidney transplantation is mostly associated with EBV infection, and the clinical manifestations are diverse. Monomorphic PTLD has a poor prognosis and high mortality.
