To evaluate the relationship of volumetric changes and endoleaks after endovascular aneurysm repair(EVAR)for abdominal aortic aneurysms(AAAs). We retrospectively evaluated the clinical and imaging data of 54 patients who had underwent EVAR within 1 month after their aneurysms were detected.All patients received abdominal and pelvic enhanced computed tomography(CTA)for two follow-up visits in Peking Union Medical College Hospital from July 2014 to February 2019.Three-dimensional volumes and maximum diameters on axial CT of the aortic aneurysms were calculated by dedicated semi-automated 3D segmentation software before surgery(V and D),in the 4 postoperative month(Vand D),and in the 12 postoperative month(Vand D),respectively.The presence or absence of endoleak for each patient with the V/V,V/V,and V/V were calculated to assess the significance of volume changes with respect to endoleaks and the correlation between volume changes and maximum diameter changes on axial CT images. Of the 54 patients,endoleaks were found in 11 patients at the first follow-up visit(4 months after surgery),among whom 8 patients were arranged a second follow-up visit(12 months after surgery),during which endoleaks were found in 5 patients.Fifteen of 43 non-leaked patients underwent a second CTA examination,which revealed endoleak in one case.Patients who did exhibit endoleaks[ =11,V/V=1.086(1.033,1.116)]showed significant increases in aneurysm volume when compared with those who did not exhbit endoleaks[ =43,V/V=1.019(0.970,1.065)]at the first follow-up visit(=-2.695,=0.007),although no significant difference was found with regard to volume changes between endoleaks(=6,V/V=1.1±0.2,V/V=1.0±0.1)and non-endoleaks(=17,V/V=1.0±0.1,V/V=1.0±0.1)at the second follow-up visit(=0.725,=0.476)as well as between these two follow-up visits(=-0.021,=0.984).V and D were moderately correlated with V and D,respectively(=0.5,<0.001)and strongly correlated with V and D,respectively(=0.8,<0.001).V and D were strongly correlated with V and D,respectively(=0.8,<0.001). The changes of aneurysm volume cannot reliably reflect the occurrence of endoleaks.The change of maximum axial diameter of aneurysm has certain correlation with the changes of aneurysm volume.

OBJECTIVE: Obesity is recognized as a significant risk factor for diabetes and hypertension. The present study aimed to examine the associations between adults'obesity risk and childhood and parental obesity. METHODS: A total of 204 children aged 6-17 years were recruited in 2002 with an average follow-up period of 13.2 years. Height and body weight were measured by trained staffs. Overweight and obesity were defined based on the Chinese standard for children and adults. T-test, analysis of variance, and Chi-square analysis were used for single factor analysis. Multiple linear and logistic regression analyses were used to perform multifactor analysis. RESULTS: The percentage of non-obese children who grew up to be non-obese adults was 62.6%, and that of obese children who grew up to be obese adults was 80.0%. There was a significant association between childhood body mass index (BMI) and adulthood BMI with a β regression coefficient of 3.76 [95% confidence interval (CI): 1.36-6.16], and between childhood obesity and adulthood obesity with an odds ratio of 5.76 (95% CI: 1.37-24.34). There was no statistical difference between parental obesity at baseline and children's adulthood obesity, after adjustment of confounders. Male participants and those aged 10.0-13.0 years had a higher risk of adulthood obesity with odds ratios of 2.50 (95% CI: 1.12-5.26) and 3.62 (95% CI: 1.17-11.24), respectively. CONCLUSION Childhood obesity is an important predictor of adulthood obesity.

Objective To study the anatomical variations of the origin of uterine artery(UA)by three-dimensional(3D)reconstructed computed tomography angiography(CTA)and facilitate the preoperative evaluation for gynecological surgeries or interventional therapies. Method The CTA findings of 112 patients with an average age of(31.4±6.6)years old who had received a pelvic CTA and undergone 3D reconstruction of the uterine artery were retrospectively analyzed. Results The average uterine volume was(95.6±26.8)cm .Of the UA 224 sides,144 sides(64.3%)arose from the interior gluteal artery and 51(22.8%)from internal iliac artery;in 29 sides(12.9%),the uterine artery,the inferior gluteal and the superior gluteal arteries arising as a trifurcation.The origin of UA was consistent between left and right sides in 68 patients(60.7%)and not in 44 patients(39.3%). Conclusion As a rapid,noninvasive,and economic technique,CTA can effectively display the anatomical variations of the origin of UA and thus can be used to guide interventional therapies and gynaecological surgeries.

Objective:To investigate the role of IL-17D to regulate the recruitment of lung NK cells and the effects of Astragalus membranaceus on IL-17D.Methods:The lung metastasis of tumor model was established by injecting B16 melanoma cells through caudal vein.After being treated with IL-17D or Astragalus membranaceus respectively,the expression of IL-17D and NK cells in lung was detected by flow cytometry and RT-PCR.Results:The production of IL-17D and the content of NK cells in the lung tumor me-tastasis model were dramatically decreased.After treatment with IL-17D,the content of NK cells in lung was significantly increased and the lung tumor foci were decreased.Along with up-regulated recruitments of NK cells,CXCL9 and IL-15,which support NK cell recruitments and maintain survival,were significantly increased.Astragalus inhibited lung tumor developments in lung by increasing the IL-17D expression and up-regulated the lung NK cell content.Conclusion: IL-17D can regulate the lung recruitment of NK cells.Astragalus mongholicus can enhance the capacity of NK cell recruitment and promote anti-tumor immune effects by up-regulating the expression of IL-17D.

Objective To explore the protective effect of gallic acid in Phyllanthus emblica on high glucose－induced apoptosis of pancreatic islet β cells, and to provide a reference for the discovery of natural compounds for the treatment of diabetes. Methods In vivo experimental model, wistar male rats were used as in vivo subjects and 50 mg/kg STZ was injected intraperitoneally. After the model was successfully established, 25 mg/kg of gallic acid was given orally, and the positive drug was Sitagliptin. After 4 weeks of administration, the blood was taken and the pancreas was removed for HE staining. Western blot was used to measure the expression of NLRP3 and TXNIP in pancreatic tissue in high sugar state. In vitro model, insulinoma cell line INS－1 cells were used as in vitro targets to establish high levels. In sugar－induced apoptosis model, INS－1 cells were cultured in glucose－free RPMI 1640 complete medium supplemented with 25 mmol/L glucose. Gallic acid was used as the test sample. Experiments were divided into normal controls, high－sugar models, and low, medium and high levels of gallic acid groups. The cell viability was measured by MTT assay. The mRNA expression of NLRP3 and TXNIP in INS－1 cells was detected by QPCR and Western blot, and the expression of NLRP3 and TXNIP protein was detected.Results (1) INS－1 cells were cultured in a medium with glucose concentration of 25mmol/L for 48h, and the apoptosis rate was increased compared with the control group (P＜0.01), indicating that the apoptosis model was established successfully under high glucose conditions. (2) 10, 5, and 2.5 μmol/L GA were used to treat the control group and the high glucose model group cells respectively. The survival rate of the control group did not change significantly (P＞0.05) . Compared with the control group, the expression of NLRP3 and TXNIP in INS－1 cells in the high glucose model group was significantly different (P＜0.05);the protein expression level was significantly downregulated after GA treatment, and there was a statistical difference (P＜0.05) . Compared with the control group, the expression of NLRP3 protein in INS－1 cells in the high glucose model group was statistically different (P＜0.01), and the protein expression level was significantly downregulated after GA treatment (P＜0.01) ; The protein expression level was up－regulated (P＜0.05);the protein expression level after GA treatment was significantly down－regulated (P＜0.05); (4) The expression of NLRP3 and TXNIP mRNA in INS－1 cells was increased in the high glucose model group compared with the control group (P＜0.01) ; The expression of protein was significantly down－regulated after GA treatment (P＜0.01) . Conclusion The cells were cultured for 48 h in glucose－free RPMI 1640 complete medium supplemented with 25 mmol/L glucose. GA has no effect on the proliferation of normal INS－1 cells. GA protects INS－1 cells from apoptosis under high glucose conditions. The mechanism may be related to GA down－regulation of NLRP3 and TXNIP gene expression.

Objective·To analyze the basic medical insurance policies for children in Shanghai in 2011 and 2017, and compare with those of the other three municipalities to understand the basic medical security status of children in four municipalities in China and analyze the existing problems. Methods?·?The current effective children's basic medical insurance policies and child critical illness insurance policies and related insurance systems in four municipalities were collected systematically. The types of basic medical insurance for children in various municipalities and their funding standards, their own expenses and the proportion of government subsidies, the proportion of outpatient emergency payoff lines and reimbursement at all levels of medical institutions, and the coverage and coverage of major illness insurance reimbursement were collected and compared mainly. Results?·?The basic medical insurance for children in Shanghai is a "double insurance" system, which contained children's hospitalization fund and basic medical insurance for urban and rural residents. The basic medical insurance for children in other municipalities mainly consisted of basic medical insurance for urban (rural) residents. Compared with 2011, the level of financing and the reimbursement of the basic medical insurance for urban and rural residents and of the children's hospitalization fund in Shanghai in 2017 was increased. In 2017, the level of financing of basic medical insurance for urban and rural residents in Shanghai was 1?100 yuan, which was slightly lower than that of Beijing medical insurance for urban residents and new rural cooperative medical insurance and was higher than that of basic medical insurance for urban and rural residents in Tianjin and Chongqing, and the individual payment level of Shanghai was the lowest. The hospitalization payoff lines in Shanghai were lower than those of other municipalities. Shanghai's outpatient and inpatient reimbursement levels were higher those of than other municipalities. There wasn't a capping line in Shanghai. There were capping lines in other municipalities. There was a great difference in the insurance policy of the major diseases in four municipalities. Conclusion?·?According to their own actual conditions, models for children's medical care systems that suited each municipalities’ social and economic development have been established. Shanghai children's basic medical insurance basically meets the needs of children's growth but needs improvement in terms of the type and level of medical security for major illnesses.

Echinacoside (ECH) is one of the active ingredients in Cistanche Herba and the principal effective component of Memoregain© as well. Moreover, a new agent namely Naoqing Zhiming tablet, derived from ECH has been licensed for clinical trials. However, the knowledge regarding the stability of is limited, till now, initiating a significant barrier for its further development along with the clinical trials. Herein, we aim to in depth characterize the transformation pattern of ECH in methanol. When ECH was stored in methanol, two primary products (P1 and P2) could be observed in HPLC chromatogram. A home-made automated fraction collector was configured via employing two 2-phase/6-port electronic valves to prepare P1 and P2. Following ¹H-NMR and LC-MS/MS assays, P1 and P2 were unambiguously identified as acteoside and cistanoside A, respectively. Moreover, the existences of cis-ECH, cis-acteoside, and cis-cistanoside A were claimed after careful analysis of the ¹H-NMR spectra of ECH, P1 and P2. Above all, the primary transformation pathways of ECH in methanol included methylation as well as hydrolysis, and mild transformation could also be initiated by cis/trans- configuration transferring for the caffeoyl group. The findings obtained in current study are envisioned to provide useful insight for the further development of ECH and the impurity detection of Naoqing Zhiming tablet. Moreover, the automated fraction collector configured in current study is able to serve as a versatile tool for the collection of signals-of-interest within phytochemical evaluations and impurity isolation.
