Objective To investigate the preventive effects of aspirin on liver metastases of colorectal cancer in mice and study the mechanisms.Methods Twenty BALB/c mice were divided into the control group and the experimental group according to the random number table with 10 mice in each group.Mice in the control group were fed with saline each day at a concentration of 0.2 mL/d for 60 days,while mice in the aspirin group were fed with aspirin each day at a concentration of 30 μg/(g · d) for 60 days.Then C26 colon cancer cells were injected into the spleen and then the spleen was cut to establish mice model of colon cancer liver metastasis.The C26 colon cancer cells were divided into 2 groups.C26 colon cancer cells in the control group remained untreated,and C26 colon cancer cells in the experimental group were treated with aspirin at a concentration of 10 mmol/L for 24 hours.The scratches and transwell assays were conducted to observe the effects of aspirin on the invasion and metastasis of C26 colon cancer cells.The expressions of epithelial-mesenchymal transition (EMT)-related genes were detected using RT-PCR and Western blot.All data were analyzed using the Student t test.The survival curve was drawn by Kaplan-Meier method,and the survival analysis was done by Log-rank test.Results The numbers and weights of hepatic metastatic tumors were 4.8 ± 1.9 and (504 ± 107) mg in the control group and 2.6 ± 1.6 and (362 ± 67) mg in the experimental group,with significant difference between the 2 groups (t =2.840,3.584,P ＜ 0.05).The 1-month survival rate was 80％ in the experimental group,which was significantly higher than 40％ of the control group (x2=4.418,P ＜ 0.05).The results of pathological examination showed that tumor cell heteromorphism was reduced by aspirin.The results of scratches experiment showed an obvious migration of C26 colon cancer cells in the control group at 24 hours later,while no C26 colon cancer cells migrated in the experimental group.The numbers of C26 colon cancer cells penetrated the Watrige were 253 ± 21 in the control group and 148 ± 13 in the experimental group,with significant difference between the 2 groups (t =5.101,P ＜0.05).The relative mRNA expression of the E-cadherin and the Vimentin were 0.002 ±0.001 and 1.005 ±0.286 in the control group and 0.005 ± 0.001 and 0.270 ± 0.168 in the experimental group,with significant difference between the 2 groups (t =-4.606,4.942,P ＜ 0.05).The relative protein expressions of the E-cadherin and the Vimentin were 0.473 ±0.179 and 0.787 ± 0.118 in the control group and 1.585 ± 0.410 and 0.280 ± 0.133 in the experimental group,with significant difference between the 2 groups (t =-5.542,6.355,P ＜ 0.05).Conclusion Aspirin inhibits liver metastasis of colon cancer and promote the survival ratio of mice.Aspirin can up-regulate the expression of E-cadherin and down-regulate the expression of Vimentin,which inhibits EMT and reduces the invasion and metastasis of tumor cells.

Objective To explore the characteristics and influential factors of resilience in empty-nest elderly with mild cognitive impairment(MCI) living in the poor area.Methods A total of 1 188 empty-nest elderly in the poor area of Hunan was sampled,analysis of covariance (ANCOVA),path analysis was used to analyze the data which were investigated by the two questionnaires including Index of SRQS.Results The prevalence of MCI in these 1 188 empty-nest elderly in rural area was 37.6％.The empty nest elderly in MCI group reported low resilience scores than those in cognitive normal group((58.84t 11.53) vs (63.58± 11.62) ; P＜0.001).ANCOVA and path analysis indicated that direct influences of income (β=3.324),education level (β=2.041),MoCA score (β=0.281) while age had indirect influences on it(β=-0.173).Conclusion Resilience in empty-nest elderly with MCI is low.Cognitive function,income and education are the direct influencing factor for resilience of the empty-nest elderly in the rural area.

Objectives To explore the influence of standardized treatment and technical flow improvement on the diagnosis and treatment of congenital diaphragmatic hernia (CDH) after prenatal diagnosis. Methods The clinical data of neonates diagnosed with CDH who were hospitalized in neonatal intensive care unit from January 2005 to August 2016 was analyzed retrospectively. Based on the start time of standardized treatment implementation, 93 cases of CDH hospitalized from January 2010 to August 2016 were divided into the intervention group while 15 cases of CDH hospitalized from January 2005 to December 2009 were divided into the control group. The survival rate and complications of clinical outcomes between two groups were compared. Results There was no significant difference in sex, gestational age, birth weight, Apgar score, and CDH position between two groups (P >0.05). The total survival rate was 81.7％ in the intervention group and 53.3％ in the control group, and there was statistical difference (P<0.05). The difference of mechanical ventilation mode and pneumothorax rate between two groups also had statistical difference (P >0.05). The median operation time in the control group was 4.5 h and the intervention group was 49.5 h. The postoperative survival rate was 61.5％ in the control group and 90.5％ in the intervention group, and the differences between two groups were significant (P >0.05). The first blood gas analysis of deaths cases in both groups showed that there were significant differences in pH and PCO2 values (P >0.05). Conclusions Optimization of the clinical management during perioperative period can improve the survival rate of CDH and reduce complications. However, the dead cases in the intervention group had more severe pulmonary hypoplasia.
