Oxygenation constants and thermodynamic parameters DeltaH degrees and DeltaS degrees of cobalt (II) complexes with bis-(furaldehyde) Schiff bases (1, 2, 3, 4)were obtained by mearsuring saturated dioxygen uptake of these complexes in pyridine at different temperature. These complexes could activate molecular oxygen and were used as catalysts in cyclohexene oxidation. The influence of ligand structure on the dioxygen affinity and catalytic activity of the complexes were discussed.

AIM To describe racial/ethnic differences in treatment and survival among liver cancer patients in a populationbased cancer *** Invasive cases of primary hepatocellular carcinoma, n = 33270, diagnosed between January 1, 1988-December 31, 2012 and reported to the California Cancer Registry were analyzed by race/ethnicity, age, gender, geographical region, socio-economic status, time period of diagnosis, stage, surgical treatment, and survival. Patients were classified into 15 racial/ethnic groups: non-Hispanic White(White, n = 12710), Hispanic(n = 8500), Chinese(n = 2723), non-Hispanic Black(Black, n = 2609), Vietnamese(n = 2063), Filipino(n = 1479), Korean(n = 1099), Japanese(n = 658), American Indian/Alaskan Native(AIAN, n = 281), Laotian/Hmong (n = 244), Cambodian(n = 233), South Asian(n = 190), Hawai`ian/Pacific Islander(n = 172), Thai(n = 95), and Other Asian(n = 214). The main outcome measures were receipt of surgical treatment, and cause-specific and all-cause *** After adjustment for socio-demographic characteristics, time period, and stage of disease, compared to Whites, Laotian/Hmong [odds ratio(OR) = 0.30, 95%CI: 0.17-0.53], Cambodian(OR = 0.65, 95%CI: 0.45-0.96), AIAN(OR = 0.66, 95%CI: 0.46-0.93), Black(OR = 0.76, 95%CI: 0.67-0.86), and Hispanic(OR = 0.78, 95%CI: 0.72-0.84) patients were less likely, whereas Chinese(OR = 1.58, 95%CI: 1.42-1.77), Koreans(OR = 1.45, 95%CI: 1.24-1.70), Japanese(OR = 1.41, 95%CI: 1.15-1.72), and Vietnamese(OR = 1.26, 95%CI: 1.12-1.42) were more likely to receive surgical treatment. After adjustment for the same covariates and treatment, cause-specific mortality was higher for Laotian/Hmong [(hazard ratio(HR) = 1.50, 95%CI: 1.29-1.73)], Cambodians(HR = 1.35, 95%CI: 1.16-1.58), and Blacks(HR = 1.07, 95%CI: 1.01-1.13), and lower for Chinese(HR = 0.82, 95%CI: 0.77-0.86), Filipinos(HR = 0.84, 95%CI: 0.78-0.90), Vietnamese(HR = 0.85, 95%CI: 0.80-0.90), Koreans(HR = 0.90, 95%CI: 0.83-0.97), and Hispanics(H

AIM To examine the largest tertiary referral center in southern and central Vietnam from 2010 to 2016, evaluating epidemiological trends of hepatocellular carcinoma(HCC) and viral hepatitis B-C in this resource-limited *** We extracted data of patients receiving care from Cho Ray Hospital(Ho Chi Minh City), the largest oncology referral center in southern and central Vietnam, from 2010 to 2016. We collected information on patient age, gender, geographic distribution, and disease characteristics including disease stage, tumor biomarker levels [serum alpha-fetoprotein(AFP), AFP-L3 isoform percentage, and prothrombin induced by induced by vitamin K absence-Ⅱ], and serological testing for hepatitis B virus(HBV) and hepatitis C virus(HCV) *** Data from 24091 HCC patients were extracted, with sample demographics comprising mostly male(81.8%) and older age(however with 8.5% younger than 40 years old). This patient sample included a geographic catchment population of 56 million people(60% of the country's total population of 92.7 million), derived from 38 provinces and municipalities in Vietnam. Chronic HBV infection was found in 62.3% of cases, and chronic HCV infection in 26.0%. HBV and HCV co-infection was seen in 2.7%. Cirrhosis was found in an estimated 30% to 40% of cases. Nine percent of patients were not found to have chronic viral hepatitis. Twenty three point two percent of the patients had a normal AFP level. A total of 2199 patients were tested with AFP-L3 and PIVKA Ⅱ over two years, with 57.7% having elevated AFP-L3%, and 88.5% with elevated PIVKA Ⅱ levels. Over this 7-year period, the incidence of HCC increased, with a large proportion of cases(overall 40.8%) presenting initially an advanced stage, not amendable to surgical or locoregional *** HCC contributes significant health care burden in southern and central Vietnam, with increasing case volume over this seven-year period.

目的调查某军医大学预选士官健康素养现状及影响因素,评价其健康教育干预效果,为基层部队开展健康素养教育提供理论依据。方法随机抽取预选卫生士官425人,对其进行为期3个月的健康教育干预,干预前后分别进行相同的健康素养调查问卷,将定量研究与定性研究相结合,验证干预效果。数据统计采用SPSS19. 0软件,方法为配对Wilcoxon检验、配对McNemar检验和多元Logistic回归。结果性别、年龄、民族、个人文化程度是影响预选士官健康素养水平的危险因素。女性的健康素养水平是男性的4. 508倍; 21~24岁卫生士官的健康素养水平是17~20岁的3. 264倍;汉族的卫生士官的健康素养水平更高;文化程度高的卫生士官,其健康素养水平也较高。健康教育干预后,预选卫生士官总的健康素养和三方面健康素养的得分及水平均增加(水平增量依次为15. 30%、3. 29%、17. 64%和12. 00%)。不同的人口学特征干预效果不同,女性健康素养的提高大于男性,家庭年收入越高,健康素养得分及水平增量也越高。吸烟人群的健康素养水平在干预前后均低于不吸烟人群,但吸烟人群的素养水平增量高于不吸烟人群。居住地为城市的预选士官在干预前后健康素养得分及水平增量均高于居住地为农村的预选士官,小学及以下文化水平的卫生士官干预前后的素养水平增量最低。结论健康教育干预可有效提高预选卫生士官的健康素养,国家及军队有关部门应实施有针对性的健康教育。
