ABSTRACT
Research participants were recruited at 16 elderly activity centers among three cities in Macao, Hong Kong and Guangzhou. A total of 324 people were surveyed, with women ≥ 55 years old and men ≥ 60 years old; There were 90, 100 and 134 in Macao, Hong Kong and Guangzhou respectively. The median (P25, P75) score of the social support rating scale (SSRS) for the elderly was 30 (25, 38) for Macao, 24 (20, 29) for Hong Kong and 30 (26, 37) for Guangzhou respectively. The elderly in Macao and Guangzhou had a higher proportion of the SSRS in the middle and high groups (85.20%, 84.50%) when compared to the elderly in Hong Kong (62.10%) (P<0.05). The city, marital status, and personal well-being index are related to SSRS scores.
ABSTRACT
Objective@#To investigate the personal wellbeing index (PWI) among elderly aged 55 and above from the elderly day care centers in Macao, Hong Kong and Guangzhou, and associated factors.@*Methods@#We used convenient sampling to select participants from 16 elderly day care centers in Macao, Hong Kong and Guangzhou. Inclusion criteria were: females aged 55 or above, males 60 or above, the participants who were conscious and clearly understood the questionnaire. Informed consent form was signed by the participants. A total of 324 elderly participated in the study: 90 from Macao, 100 from Hong Kong, and 134 from Guangzhou. Close-end questionnaire was used to collect demographic information and PWI inventory (Cantonese version) was used to assess the PWI scores. Comparison in the PWI scores difference was conducted. Multiple regression method was used to analyze factors associated with PWI.@*Results@#The PWI was 7.3±1.9 (Macao: 7.7±1.9, Hong Kong: 7.2±1.7, Guangzhou: 7.0±1.9) (F=3.32, P=0.037). The multiple regression analysis showed that comparing to those who did exercised 3 times or less, or single/devoiced/separated, or had no education, the elderly who did exercised 4 times or more per week or married/widowed, or received education in primary school or above had higher PWI scores. The beta values (95%CI) were 0.82 (95% CI: 0.31-1.34), 1.03 (95% CI: 0.12-1.94), 0.51 (95% CI: 0.04-0.99) respectively.@*Conclusion@#The elderly participants aged 55 or above who went to elderly day care centers in three cities had higher PWI score generally. Marital status, participate in sufficient physical activity and advanced education level were significant related to PWI.
ABSTRACT
Objective To identify the genotypos of extended spectrum β-1actamase (ESBLs)-producing of Escherichia coli ( E. coli) clinical strains isolated from the Macao and compare the results with the genotypes of clinical strains collected in the first Clinical College, China Medical University (CMU) in Shengyang. Methods The clinically isolated E. coli strains including 209 strains from Macao and 150 strains from CMU were collected. Based on the standard of CLSI2006, the ESBLs-producing strains was identified and its isoelectric point(pI) value was detected by isoelectric focusing (IEF) method. The pI values were used to design the primers for PCR amplification. The amplified DNA sequences were then compared with the GenBank and the ESBL genotypes were confirmed. Results ( 1 ) The positive rate of ESBLs-producing strains of E. coli was 30. 1% (62/209) from Macao and 54. 0% (81/150)from CMU. (2)The genotype of 56 (90. 5% ) β-lactamase(ESBLs)-producing E. cull strains from Macao was CTX-M56. Most of them were CTX-M-14 (76. 2% ), other genotypes including CTX-M-9 (4. 8% ), CTX-M-22 (3.2%), CTX-M-24(3.2%), CTX-M-27(1. 6% ), and CTX-M-15( 1.6% ) were found. Six strains were unidentified. (3)The genotype of 74(91.5% )β-lactamase(ESBLs) -producing E. coli strains from Shenyang was CTX-M. Most of them were CTX-M-14 (65.4%), other genotypes including CTX-M-3 ( 13.6% ), CTX-M-24 (4. 9% ),CTX-M-22(2.5%), CTX-M-15(2.5%), CTX-M-9(1.2%) and CTX-M-28(1.2%) were found. Seven strains were unidentified. Conclusions CTX-M genotypo was the mostly identified ESBL-preducing E. Coli strains from Macao and the results were similar with that from CMU. Among them, the CTX-M-14 was the major genotype. Other genotypes included CTX-M-9, CTX-M-15, CTX-M-22, CTX-M-27, and CTX-M-24.However, two genotypes of CTX-M-3 and CTX-M-28 were not found in the clinical isolates in Macao and one genotype of CTX-M-27 was not found from the CMU clinical isolates.
ABSTRACT
<p><b>BACKGROUND</b>Finding the cancer cells in pleural fluid of patients with lung can-cer by conventional cytology is always a difficult point. In order to enhance the diagnostic rate of pleural fluid with lung cancer, carcinoembryonic antigen (CEA) and cancer antigen 153 (CA153) were detected in serum and pleural fluid, and their diagnostic values on lung cancer were analyzed.</p><p><b>METHODS</b>Quantities of CEA and CA153 were detected by chemiluminescence in both serum and pleural fluid of patients with lung cancer (74 cases) and without lung cancer (34 cases).</p><p><b>RESULTS</b>The levels of CEA and CA153 in pleural fluid of patients with lung cancer were significantly higher than those without lung cancer (P < 0.01). The levels of CEA and CA153 in serum of patients with lung cancer were distinctly higher than those without lung cancer (P < 0.01). The levels of CEA and CA153 in pleural fluid were obviously higher than those in serum (P < 0.01). The optimal diagnostic assay of lung cancer was CEA+CA153 combination: sensitivity and specificity were 85.1% and 97.1% respectively.</p><p><b>CONCLUSIONS</b>It could be of important clinical significance for diagnosing lung cancer by assaying CEA and CA153 in pleural fluid of patients with lung cancer.</p>
