BACKGROUND: At present, most researches on simulated weightlessness are confined to its effect on the artery. Therefore, the effect on the vein needs to be further studied.OBJECTIVE: To probe into the effect of simulated weightlessness on the ultrastructure of rabbit femoral vein and the remodeling of femoral vein.DESIGN: A completely randomized and controlled trial based on experimental animals.SETTING: Department of Aerospace and Aviation Medical Science, Fourth Military Medical University of Chinese PLA.MATERIALS: The experiment was completed in the Department of Aerospace and Aviation Medical Science, Fourth Military Medical University of Chinese PLA from December 2000 to December 2001. Altogether 24healthy male New Zealand rabbits, weighing 2.0-2.5 kg were obtained.INTERVENTIONS: The model of Head-Down Tilt( -20°) (HDT) simulated weightlessness was established in rabbits. A total of 24 healthy male New Zealand rabbits were randomly divided into control group, 10-day simulated weightlessness group and 21-day simulated weightlessness group, with 8rabbits in each group. The ultrastructure of the rabbit femoral vein was observed under transmission electron microscope.MAIN OUTCOME MEASURES: Changes and degeneration of endothelial cell, mitochondrion, internal elastic membrane, and smooth muscle.RESULTS: Cell organelles in endothelial cell of the femoral vein of HDT rabbits decreased, mitochondrion dissolved and disappeared, vacuolar degeneration in endothelial cell increased and phagolysosome in endothelial cell could be found. Internal elastic membrane became thinner and was broken. The smooth muscle layer became thinner and some smooth muscle cells became degenerated. Cell interstitial substance increased. There was significant difference in changes between 21-day and 10-day simulated weightlessness groups.CONCLUSION: The vascular remodeling of femoral vein occurs with atrophic changes during simulated weightlessness. The longer duration of simulated weightlessness is, the more obviously the structure of femoral vein changes.

The detection values of AMH, INHB, LH, T and SHBG in PCOS group were higher than those in control group (the t values were 9.843, 7.373, 9.021, 9.349 and 3.867), and the difference was statistically significant (P<0.05). The detection values of E2 and FSH in PCOS group were lower than those in control group(the t values were 0.762 and -1.342), with no significant difference (P>0.05). The INHB/AMH value was lower than that in control group(the t value was -2.332), and the difference was statistically significant(P<0.05). The area under the curve of AMH, INHB and AMH+INHB in the diagnosis of PCOS was 0.762, 0.677 and 0.789, respectively. The cut-off value of AMH in predicting polycystic ovary syndrome was 6.96 ng/mL, the sensitivity was 61.0％, and the specificity was 82.1％. The cut-off value of INHB in predicting polycystic ovary syndrome was 94.9 pg/mL, with a sensitivity of 59.0％ and a specificity of 74.1％. The sensitivity and specificity of combined detection of AMH and INHB in predicting polycystic ovary syndrome were 83.6％ and 60.6％. The positive rates of ultrasound, T, AMH and INHB in PCOS group were 51.25％, 61.25％, 69.58％ and 66.25％, respectively. Conclusion The combined detection of AMH and INHB may improve the sensitivity and specificity of PCOS diagnosis, and its serum level is stable.

Objective To investigate the clinical significance of Epstein-Barr virus EBV DNA in children with Epstein-Barr virus infection realated diseases.Methods A retrospective cohort study was performed.Totally 222 blood samples were collected from children who were diagnosed as EBV infection in Shandong Provincial Hospital from June 2012 to August 2013.Fluorescent quantitative PCR( FQ-PCR) was used to analyze the EBV DNA in peripheral blood lymphocytes.ELISA was used to analyze the four EBV serology antibodies in the serum.Two groups of tested results were compared.Heart, hepatic impairment and renal function were analyzed through detecting AST, ALT, BUN, CREA, CK, CKMB.The results were grouped by EBV DNA copy number, and then non-parametric test together with correlation analysis was performed using SPSS21.0 analytics software.Results The positive rate of EBV-CA IgM and EBV DNA was 51.35%(114/222) and 72.97% (162/222) respectively, χ2 =24.01, P<0.001.The EBV DNA copy number was significant difference (χ2 =11.79,P<0.05) in children at different stages of infection ( no previous infection:6.30 ×103 -1.20 ×104 copies/ml;early infection:5.56 ×103 -3.92 ×106 copies/ml;acute infection:6.58 ×103 -1.73 ×106 copies /ml;chronic infection or recurrent infection:8.92 ×103 -2.34 ×104 copies/ml;late infection or recovery:5.20 ×103 -1.12 ×107 copies/ml;past infection:5.46 × 103 -1.33 ×104 copies/ml).Each biochemical targets were divided into five groups by EBV DNA copy number (Ⅰ>1 ×106 copies/ml,Ⅱ1 ×105 -1 ×106 copies/ml, Ⅲ1 ×104 -1 ×105 copies/ml, Ⅳ5 × 103 -1 ×104 copies/ml, Ⅴ<5 ×103 copies/ml), and ALT(χ2 =10.14,P<0.05), BUN(χ2 =18.17, P<0.05), CK(χ2 =13.09,P<0.05), CKMB(χ2 =17.93,P<0.01) had a statistically significant difference between each group.Well, the log value of EBV DNA copy number had a positive correlation relationship with AST(r=0.357,P=0.001), ALT(r=0.376,P=0.001), BUN(r=0.329,P=0.000), CK(r=0.235,P=0.035).Conclusions Detection of EBV DNA can be used for the early diagnosis and assessment of process of the EBV infection related disease in children.The detection of liver, kidney function and myocardial enzymes can be used for evaluating the severity of EBV infection.

Caudal type homeobox transcription factor 2 (CDX2) is an enteric-specific nuclear transcription factor, which is mainly expressed in the small intestine and colorectum and not expressed in normal gastric mucosa. CDX2 is involved in the occurrence, development, invasion and metastasis of gastrointestinal tumors, and its expression state is related to the clinicopathological characteristics and prognosis of patients with gastrointestinal tumors. It is expected to provide a new idea for the diagnosis and treatment of gastrointestinal tumors by further studying the mechanism of CDX2 involvement in tumor genesis and development and its relationship with clinicopathological features and prognosis.

Objective:To analyze the current status and existing problems of the research on social health in the rural elderly in China so as to provide a reference for further research on improving the social health of the rural elderly, promoting healthy and active aging.Methods:We systematically searched the research on the social health of the rural elderly published in the China National Knowledge Infrastructure (CNKI) , VIP and WanFang Data from January 1, 2009 to December 31, 2018. The literature on the social health of the rural elderly in China were analyzed from the literature year, first author, published journals, research institutions and fund sources with the bibliometric method, EndNote and Excel.Results:A total of 149 journal articles were included. The literature number of the research on social health of the rural elderly showed an upward trend from 2009 to 2015, and then the trend was stable; 50.34% (75/149) of the literatures were published in Peking University Chinese core journals, and 66.44% (99/149) of the literatures were supported by fund projects; the first author was from 21 provinces and 3 municipalities; the research team has not formed a "scientific elite group", and various types of institutions have carried out research on the social health of the rural elderly in China; tools for measuring social health included the Social Support Rating Scale, Medical Outcomes Study 36-Item Short Form Health Survey and the Self-designed Questionnaires.Conclusions:In recent years, more and more attention has been paid to research on the social health of the rural elderly in China. However, the research area and institutions were wide and varied, and the research team has not formed a "scientific elite group"; social health-related concepts still lack a unified research standard and a comprehensive measurement tool for the social health of the rural elderly. We hope that many scholars will invest in the field of social health and make efforts to promote active aging.
