RESUMEN
Minimal hepatic encephalopathy(MHE) is an early stage of hepatic encephalopathy with an insidious onset and a high rate of missed diagnosis in clinical practice, and it is of great importance to diagnose MHE as early as possible and provide effective clinical intervention. There are many diagnostic methods for MHE, among which psychometric hepatic encephalopathy score is the most commonly used method at present, but its wide application in clinical practice is limited by its complex and time-consuming operation, and therefore, it is urgent to find a simple, rapid, and effective clinical diagnostic method. Stroop test is a test for psychomotor speed and cognitive flexibility, and its value in the diagnosis of MHE has been verified in various countries including the United States and South Korea. This article introduces the development of Stroop test and its application in MHE, and the analysis shows that Stroop test based on mobile devices has a high sensitivity in the diagnosis of MHE and is simple, convenient, and feasible. It is hoped that this test can be widely used in the clinical work of MHE screening in China in the future.
RESUMEN
Objective To evaluate the feasible cervical cancer screening strategies in rural China. Methods The study was based on the health industry scientific research project of National Health Commission in 2015, cervical cancer screening technology and demonstration research suitable for rural areas in China, we collected health economics and epidemiological parameters and established the unscreening model and screening model with Treeage Pro 2011 software. Combining with the data acquired from site investigation, including population screening, treatment-related clinical materials and cost data, we simulated the occurrence and the development of cervical cancer of rural women in China under different screening and intervention programs and predicted the screening effects [cumulative incidence, cumulative risk of disease, life years and quality adjusted life years (QALY), gains] and costs after 20 years, and using health economic evaluation analysis (cost-effectiveness analysis, cost-utility analysis, cost-benefit analysis). Screening programs included five screening strategies [visual inspection with acetic acid/lugol's iodine (VIA/VILI), careHPV, ThinPrep cytology test (TCT), careHPV+TCT, careHPV+VIA/VILI] and three screening intervals (1-year, 3-year, 5-year), a total of fifteen screening programs. Results Compared with no screening, fifteen screening programs reduced the cumulative incidence by 22.65%-51.76%. Compared with TCT or VIA/VILI, for the same screening interval, the reduced cumulative incidence, the amounts of life-year saved and QALY and benefits gained of careHPV were the highest. The cost-effectiveness ratios of these screening programs ranged (0.44-3.24)×104 Yuan per life-year saved, cost-utility ratios ranged (0.15-1.01)×104 Yuan per QALY, benefit-cost ratios ranged 7.73-59.10. The results of incremental cost-effectiveness ratios showed that VIA/VILI every five years, VIA/VILI every three years, careHPV every five years, careHPV every three years and careHPV every year were dominant programs. Conclusions VIA/VILI screening is cost-effective, careHPV is slightly more expensive but more effective. In rural China, careHPV screening every five years could be recommended. This study provides a basis for the determination of cervical cancer screening methods feasible for rural areas in China.

RESUMEN
OBJECTIVE:To investigate the inhibitory effect of astragalus polysaccharide(APS)on the proliferation of human neuroblastoma SH-SY5Y cells. METHODS:After the cells were cultured with 0(blank control),25,50 and 100 mg/ml APS for 6,12 and 24 h,MTT method was used to determine cell viability and calculate inhibition rate. Following cell cultured with 0 (blank control),25,50 and 100 mg/ml APS for 24 h,Hoechst 33258 fluorescent staining was performed,and then cell nucleus morphology was observed under the fluorescence microscope;flow cytometer was used to detect the distribution of cell cycles and apoptosis;western blot was employed to determine the expression of extracellular regulated protein kinases (ERK) 1/2 protein in cells. Enzyme linked immunosorbent assay (ELISA) was conducted to determine the contents of interleukin 2 (IL-2),IL-6 and IL-12 in the cells. RESULTS:Compared to the blank control,those cultured with 100 mg/ml APS for 6 h,50 and 100 mg/ml APS for 12 h and 25,50 and 100 mg/ml APS for 24 h demonstrated higher inhibition rate. After the cells were cultured with 50 and 100 mg/ml APS for 24 h,those in G0/G1 phase increased and those in G2/M and S phases decreased,and the contents of IL-2 and IL-6 increased. After cells were cultured with 25,50 and 100 mg/ml APS for 24 h,the apoptosis rate was higher,densely hyperchromat-ic fragments in cell nuclei and apoptotic bodies appeared,the phosphorylation level of ERK1/2 protein in the cells was lower,and the content of IL-12 was higher. There was statistically significance (P<0.01 or P<0.05). CONCLUSIONS:APS can inhibit the proliferation of SH-SY5Y cells by arresting cell cycle and inducing cell apoptosis through a mechanism which may be correlated to the decrease in the phosphorylation of ERK1/2 and increase in cytokine.

OBJECTIVED: To explore the prevalence and risk factors of type 2 diabetes mellitus (T2DM) and impaired glucose regulation (IGR) in Zhangzi Island of Dalian, additionally to provide a better understanding of further intervention. METHODS: A cross-sectional study was performed in 907 residents aged over 18 years from Zhangzi Island of Dalian. The questionnaire, physical measurement, food intake frequency and previously dietary investigation were used in the analysis. Simultaneously, a series of biochemistrical and immune index was measured, including blood uric acid, blood sugar, total cholesterol, triacylglycerol, as well as serum insulin.RESULTS: The recovery rate of questionnaire was 95.9%, which demonstrated that the prevalence rates of T2DM and IGR in Zhangzi Island were 11.36% and 37.38%, there was no significant differences between males and females (P > 0.05). Only 29.13% of the people with T2DM were aware of the condition. The prevalence of DM and IGR were increased significantly with age (P < 0.01). The results of the logistic regression showed that age, education, alcohol drinking and hypercholesteremia were the risk factors of IGR. In addition, age, education, hypercholesteremia, hypertriglyceridemia, body mass index and hypertension were the important risk factors for the development of DM. CONCLUSION: The prevalence rates of T2DM and IGR in Zhangzi Island of Dalian are high with a low awareness. Health promotion on lifestyle changes may help to increase the public awareness and reduce the prevalence.
