Objective Artificial atrial septum defect combining pulmonary artery banding to create a model of congenital heart defect with decreased pulmonary blood flow to explore the morphological changes of immature pulmonary vascular. Methods Choose twenty piglets with about one to two-month-old, which are exclusively for experiment used. The piglets were randomly divided into three groups: normal control group (group C, n = 6), Small incisions on the right chest, produced a transient reduction in pulmonary blood; low-medium pulmonary artery stenosis groups ( group T1, n = 7 ) : Did artificial room septostomy creation by self-dilators which were delivered into the surface of the right atrium and controlled Systolic trans pulmonary artery banding pressure (Trans-PABP) at pressure of 20 - 30 mmHg; severe pulmonary artery stenosis groups ( group T2, n = 7): T2 were the same surgical procedures with group T1 ,and controlled Trans-PABP ≥ 30 -50 mmHg. Monitored ultrasound after operation , carried out 64-slice computed tomography scanning after one month, to measure the proximal vessel diameter and TransPABP , after two month surgical exploration on the left chest. When the animals were sacrificed, the heart and lung tissue was cut to measure atrial septal defect, pulmonary artery and the banding diameter. By weihgt elastic fiber and van Cieson staining to observe the morphological pathological changes, three groups took lung tissue with right middle lobe lateral segment about 1.0 cm × 0.8 cm × 0.8cm at the end of surgery and 2-months after operation respectively. Results The models were all successfully in the survival animal of the two test groups. One pig died from tracheal intubation accident in the C group, there was one case died due to bowel obstruction in the T1 group, And there were two cases died result from acute right heart failure and chronic heart failure respectively in T2 group. 64-slice CT angiography showed that BD was significantly lower than the AOD in the two test groups, the proximal pulmonary vascular expansion result from stenosis, distal pulmonary vascular scarce. Histopathology showed that the pulmonary artery inside diameter of T1 and T2 was significantly higher than group C(P ＜0. 05,P ＜ 0.01), and the NAPSC of two experimental groups were significantly lower than group C 2-month after operation( P ＜0.01).Conclusion This type of Piglet model is closer to clinical pathological and physiological ,64-slice spiral CT combined with lung histopathology observed for the evaluation of pulmonary vascular hypoplasia is a reliable method. Tunica media of pulmonary arterioles hypoplasia with the number reducing, with pulmonary artery banding increased,the degree of pulmonary arterioles hypoplasia gradually increased.

Objective To investigate the relationship between interleukin-18(IL-18)and the pathogenesis of type 2 diabetes melli-tus.Methods 72 healthy Sprague-Dawlay male rats were randomly divided into four groups, NC group,NCS group,HF group and HFS group.At the end of the 8th week,NCS group and HFS group were injected with STZ(25mg/kg)into abdominal cavity.At the end of the 10th week,diabetic rats were screened by oral glucose tolerance test(OGTT).The blood sample was collected when the rats were killed at the end of the 14th and 20th week.The levels of serum IL-18,IL-6 and tumor necrosis factor-α(TNF-α)were assayed with ELISA.Results Most rats in HFS group were achieved the diagnostic standard of diabetic rat, and their insulin sensitivity index(ISI)were decreased.At the end of the 14th week and 20th week,the levels of serum IL-18,IL-6 and TNF-α in HFS group were significantly higher than those in NC group(P＜0.01).In HFS group,the levels of serum IL-18,IL-6 and TNF-α at the end of the 20th week were higher than those at the end of the 14th week,but it had no statistic significance(P＞0.05).Pearson linear correlation analysis showed that the level of serum IL-18 in HFS group was positive correlated with FBG,IL-6,and TNF-α(r=0.90,P＜0.01 or r≥0.73,P＜0.05),and negative correlated with ISI(r=-0.86,P＜0.01).Condusions Our results show that IL-18 is related with the pathogenesis of type 2 diabetes mellitus and chronic inflammation plays an important role in the development of type 2 diabetos mellitus.

Objective:Sirtuins family is involved in the regulation of many biological events in the cells of the body. As one of the important members, SIRT1 may participate in the formation and development of colorectal cancer. We detected the expression of SIRT1 in colorectal cancer and adjacent normal mucosa to explore its role and significance in the pathogenesis of colorectal cancer.Methods:One hundred and twenty surgical specimens of patients from Xinhua Hospital Affiliated to Dalian University who were hospitalized for colorectal cancer from January 2018 to July 2018 were selected as experimental group. The normal mucosa tissues more than 10 cm away from the tumor focus were taken as the control group. The expression of SIRT1 in colorectal cancer and normal mucosa was detected by immunohistochemistry SP method and Western blot. The different expression of SIRT1 in different organs of digestive tract and parts of human system was compared with Expression Atlas Database. The relationship between SIRT1 expression and clinical pathological data was analyzed to explore the role and significance of SIRT1 in colorectal cancer.Results:SIRT1 protein was mainly expressed in the tumor cell nucleus. The positive staining was brownish yellow, and it was highly expressed in rectal cancer; Sirt1 expression was positively correlated with the depth of tumor invasion, differentiation and tumor size, and the difference was statistically significant ( P<0.05); SIRT1 was highly expressed in human digestive tract, but there was no significant difference in the expression of SIRT1 in various organs of digestive tract; Sirt1 may function through the PI3K-AKT signaling pathway in colorectal cancer. Conclusions:SIRT1 plays the role of oncogene in the development of colorectal cancer, and increasing expression of SIRT1 promotes the development of colorectal cancer. SIRT1 may be a marker of early diagnosis of colorectal cancer, which is of great significance.

Objective: To investigate the prevalence of reproductive system diseases among female workers in a city and related occupational influencing factors. Methods: From June to September, 2016, a cross-sectional survey was used to select 9 944 female workers from six districts of Beijing and then a face-to-face questionnaire survey was performed. Univariate analysis using chi-square test and multivariate logistic regression analysis were used to investigate the risk factors for reproductive system diseases. Results: The age of 9944 female workers ranged from 18 to 65 years (mean 35.53±9.52 years) , and among them, 7 351 (73.92%) were married. The overall prevalence rate of reproductive system diseases among these 9944 female workers during the past three months was 28.29%, and the prevalence rates of hyperplasia of mammary glands, vaginitis, and hysteromyoma were 15.54%, 11.25%, and 6.77%, respectively. After adjustment for age, marital status, education level, and annual family income, the multivariate logistic regression analysis showed that frequent overtime work (odds ratio[OR]=1.119, 95% confidence interval[CI]: 1.070-1.343) , frequent night shifts (OR=1.198, 95%CI: 1.054-1.361) , standing for a long time (OR=1.197, 95%CI: 1.063-1.347) , sitting for a long time (OR=1.327, 95%CI: 1.191-1.479) , heavy workload (OR=1.429, 95%CI: 1.262-1.615) , exposure to lead (OR=1.696, 95%CI: 1.307-2.201) , exposure to mercury (OR=1.452, 95%CI: 1.086-1.940) , and exposure to ionizing radiation (OR=1.679, 95%CI: 1.424-1.980) were associated with reproductive system diseases. Conclusion The prevalence of reproductive system diseases among female workers in Beijing is not optimistic. Reproductive system diseases are associated with frequent overtime work, frequent night shifts, standing for a long time, sitting for a long time, heavy workload, and exposure to lead, mercury, and ionizing radiation.
