Abstract
Emerging evidence has been reported to support the involvement of the gut microbiota in the host's blood lipid and hyperlipidemia (HLP). However, there remains unexplained variation in the host's blood lipid phenotype. Herein a nonhuman primate HLP model was established in cynomolgus monkeys fed a high-fat diet (HFD) for 19 months. At month 19%, 60% (3/5) of the HFD monkeys developed HLP, but surprisingly 40% of them (2/5) exhibited strong tolerance to the HFD (HFD-T) with their blood lipid profiles returning to normal levels. Metagenomic analysis was used to investigate the compositional changes in the gut microbiota in these monkeys. Furthermore, the relative abundance of Megasphaera remarkably increased and became the dominant gut microbe in HFD-T monkeys. A validation experiment showed that transplantation of fecal microbiota from HFD-T monkeys reduced the blood lipid levels and hepatic steatosis in HLP rats. Furthermore, the relative abundance of Megasphaera significantly increased in rats receiving transplantation, confirming the successful colonization of the microbe in the host and its correlation with the change of the host's blood lipid profiles. Our results thus suggested a potentially pivotal lipid-lowering role of Megasphaera in the gut microbiota, which could contribute to the variation in the host's blood lipid phenotype.

Abstract
Recent population studies have significantly advanced our understanding of how age shapes the gut microbiota. However, the actual role of age could be inevitably confounded due to the complex and variable environmental factors in human populations. A well-controlled environment is thus necessary to reduce undesirable confounding effects, and recapitulate age-dependent changes in the gut microbiota of healthy primates. Herein we performed 16S rRNA gene sequencing, characterized the age-associated gut microbial profiles from infant to elderly crab-eating macaques reared in captivity, and systemically revealed the lifelong dynamic changes of the primate gut microbiota. While the most significant age-associated taxa were mainly found as commensals such as Faecalibacterium, the abundance of a group of suspicious pathogens such as Helicobacter was exclusively increased in infants, underlining their potential role in host development. Importantly, topology analysis indicated that the network connectivity of gut microbiota was even more age-dependent than taxonomic diversity, and its tremendous decline with age could probably be linked to healthy aging. Moreover, we identified key driver microbes responsible for such age-dependent network changes, which were further linked to altered metabolic functions of lipids, carbohydrates, and amino acids, as well as phenotypes in the microbial community. The current study thus demonstrates the lifelong age-dependent changes and their driver microbes in the primate gut microbiota, and provides new insights into their roles in the development and healthy aging of their hosts.

Abstract
Objective: To explore the application value of 99Tcm-diethylenetriaminepentaacetic acid (DTPA) orbital single photon emission computed tomography/computed tomography (SPECT/CT) in staging evaluation of thyroid associated ophthalmopathy (TAO). Methods: A case-control study. A total of 40 patients with binocular TAO were recruited from May 2019 to December 2019 in the Second Hospital of Dalian Medical University. According to the clinical activity score (CAS) standard, 40 TAO patients were divided into the active group (15 cases) and the inactive group (25 cases), and 10 healthy volunteers were recruited as the control group. All subjects underwent 99Tcm-DTPA orbital SPECT/CT examination, and each subject's CAS, reading results and maximum standardized uptake value (SUVmax) were recorded. The Kruskal-Walis H test was used for the CAS comparison among the three groups. The analysis of variance was used for the SUVmax comparison among the three groups. The comparison between CAS and SUVmax before and after treatment was performed by paired samples Wilcoxon signed rank test and paired-sample t test, and Spearman correlation analysis was performed between SUVmax and CAS. The Kappa test was used to check the consistency between the reading result and CAS's judgment of TAO activity. The receiver operating characteristic curve was used to analyze the diagnostic value of the reading results and SUVmax for TAO. Results: The age difference among the three groups was not statistically significant, and the gender difference was not statistically significant (all P>0.05). The difference in CAS among the three groups was statistically significant (H=39.894; P<0.01). Patients with active TAO showed abnormal concentration and enhancement of nuclides in the orbital tissue, and the uptake of radionuclides was significantly increased, while patients with inactive TAO had a slight increase, and healthy volunteers had no significant or only mild uptake. The SUVmax of the active group (2.24±0.47) was highest, and that of the inactive group (1.57±0.43) was higher than the healthy control group (0.67±0.22). After pairwise comparison, there were statistical differences between groups (all P<0.05). According to Spearman correlation analysis, the SUVmax of all TAO patients was linearly, positively correlated with their CAS (r=0.753; P<0.05). In assessing the clinical activity of TAO, the reading results were consistent with CAS (Kappa value=0.737; P<0.05). Taking the reading results as the standard, the area under the receiver operating characteristic curve (AUC) of SUVmax was 0.992, and the threshold of SUVmax to distinguish between active and inactive periods was 1.850, with a sensitivity of 86.70% and a specificity of 76.00%. Taking CAS results as the standard, the AUC of SUVmax was 0.853, and the threshold of SUVmax to distinguish between active and inactive periods was 1.850, with a sensitivity of 100.00% and a specificity of 87.50%. Five patients had inconsistent SUVmax and CAS. The CAS was ≥3, but the orbits did not show any inflammatory lesions in two of them; the CAS was<3, but the orbits showed inflammatory lesions in three of them. Thirteen active TAO patients with 99Tcm-DTPA orbital SPECT/CT showing significant accumulation of nuclides were given hormone shock therapy 12 times. After treatment, the CAS 2.00 (2.00) was lower than the pre-treatment 3.00 (1.50) score, and the difference was statistically significant (Z=-3.100, P<0.01). The SUVmax after treatment (1.60±0.20) was lower than the pre-treatment value (2.17±0.34), and the difference was statistically significant (t=10.197, P<0.01). Conclusion: 99Tcm-DTPA orbital SPECT/CT can relatively accurately determine the state of orbital inflammation in patients with TAO, and can be used as a useful supplement to evaluate the clinical activity of TAO, helping to guide clinical treatment.

Abstract
Daclizumab is a humanized monoclonal antibody that prevents interleukin-2 (IL-2) binding to CD25, blocking IL-2 signaling by cells that require high-affinity IL-2 receptors to mediate IL-2 signaling. The phase 2a CHOICE study evaluating daclizumab as a treatment for multiple sclerosis (MS) included longitudinal analysis of activated T cell counts. Whereas an exposure-dependent relationship was observed between daclizumab and reductions in HLA-DR(+)-activated T cells, a similar relationship was not observed for reductions in CD25 levels. The objective of this report is to determine the mechanism by which daclizumab reduces CD25 levels on peripheral blood mononuclear cells (PBMCs) using cytometric techniques. Daclizumab reduced T cell CD25 levels through a mechanism that required the daclizumab-Fc domain interaction with Fc receptors (FcR) on monocytes, but not on natural killer (NK) cells, and was unrelated to internalization or cell killing. Activated CD4(+) T cells and FoxP3(+) Treg cells showed evidence of trogocytosis of the CD25 antigen in the presence of monocytes. A daclizumab variant that retained affinity for CD25 but lacked FcR binding did not induce trogocytosis and was significantly less potent as an inhibitor of IL-2-induced proliferation of PBMCs. In conclusion, Daclizumab-induced monocyte-mediated trogocytosis of CD25 from T cells appears to be an additional mechanism contributing to daclizumab inhibition of IL-2 signaling.

Abstract
The authors investigated the possibility that, in interview-based case-control studies, controls are more likely than cases to underreport a history of induced abortion. A case-control study was conducted in White women under 45 years of age who had given birth in Washington State during 1984-1994. The cases were women in three metropolitan counties of Washington State diagnosed with invasive breast cancer during 1984-1994; controls were selected through random digit dialing. A history of induced abortion among study participants was compared between interview data and information collected on the birth record of the last child to whom they gave birth (225 cases, 303 controls). Among women with a prior induced abortion recorded on the birth record, 14.0% of the 43 cases and 14.9% of the 47 controls did not report an induced abortion at interview (difference = -0.9%, 95% confidence interval of the difference: -15, 14). The authors' data do not suggest that controls are more reluctant to report a history of induced abortion than are women with breast cancer.

Abstract
We wished to assess the relation of induced abortion to the subsequent incidence of breast cancer among parous women, using a design that would prevent the possibility of differentially complete reporting of abortion history by women with breast cancer and controls. Our study was conducted within a cohort of women who gave birth to a child during 1984-1994 while residing in 13 counties of western Washington. Cases were women from the cohort diagnosed with breast cancer between 1984 and 1994. From the remaining cohort members, five controls were matched to each woman with breast cancer by year of index birth (ie, the last child born before breast cancer diagnosis) and by age at delivery. We categorized 463 cases and 2,201 controls according to history of induced abortion as recorded on the index birth certificate. The risk of breast cancer was not found to be associated with a prior induced abortion (estimated relative risk (RR) = 0.9, 95% confidence interval (CI) 0.7-1.2). These results suggest that an induced abortion, if followed at some later time by pregnancy and childbirth, does not increase a woman's risk of breast cancer.

Abstract
Six patients suffering from ovarian sex cord tumor with annular tubules (SCTAT) were reported in this article with special reference to the clinical features, histological characteristics, sex hormone profile, and management of disease. SCTAT was documented to be a estrogen-progesterone-secreting tumor based on the observations of glandular atrophy and decidual change of stroma in the endometrium and assays of steroid hormone. Menometrorrhagia followed by persistent amenorrhea and pelvic mass were presented as important clinical features. This tumor was considered as a tumor with low-grade malignancy, and retroperitoneal lymphatic metastasis was thought to be an important pathway of spread. Unilateral salpingo-oophorectomy together with ipsilateral pelvic and para-aortic lymphadenectomy were suggested as an effective treatment for SCTAT. Radiotherapy can be used for local recurrence and distant metastases.
