Objective: To study the impression of Chinese people on Chinese urban children, their main source of information about the Chinese people, and the infvuence of age, school, and gender upon their evaluation. Methods: 383 Chinese urban children ranging from 5 to 12 years were interviewed individually or investigated with the questionnaire. Results: Most of the children reported that the Chinese were happy, clean, peaceful, clever, hardworking, kind and nice. However, the urban children's positive impression of the Chinese people was decreased with their growing up. The study also found that children's information on the Chinese people was mainly in order from television, newspapers, books and cartoons, parents, classmates, friends and teachers, and radio, and that the information source became increasingly diversificed with age. No significant difference in gender and between two schools was found. Conclusion: Chinese urban children had a positive impression of Chinese people, and they had a preference and identity for Chinese people . Mass media were the main source of information.

China Occupational Medicine 2022;49(2):165-170
Objective To analyze the epidemiological characteristics of hospital admission cases with chemical poisoning in
Guangdong Province from 2016 to 2020. Methods Data of hospital admissions for chemical poisoning in Guangdong Province
from 2016 to 2020 were collected through Guangdong Province Health Statistics Network Reporting System,and descriptive
analysis was conducted. The seasonal characteristics of the number of hospitalized poisoning cases were analyzed by the
concentration method,the seasonal index(SI)was calculated by the weighted annual ratio averaging method,and the spatial
auto-correlation of regional poisoning trend was analyzed by the global and local spatial autocorrelation. Results From 2016 to
2020,the number of hospital admissions for chemical poisoning in Guangdong Province was 54 656,showing a general
decreasing trend. The sex ratio(male to female)was 0.90 ∶1.00. The top three types of hospitalization rates were carbon
monoxide poisoning,alcohol poisoning and organic solvent poisoning. The main poisoning groups were students and children,
farmers,workers and unemployed people,accounting for 31.74%,18.53%,13.91% and 10.39%,respectively. The 74.37% of
poisoning cases were cured or improved and discharged,and the case fatality rate was 0.48%. The top three hospitalization rates
in age group of 0-<5 years were organic solvent,metal and carbon monoxide poisoning. The hospitalization rate of carbon
monoxide poisoning ranked the first among all age groups of ≥5 years. The top three regions with the highest average annual
hospitalization rate were Shaoguan City (25.14/105
),Qingyuan City (17.04/105
) and Meizhou City (16.09/105
). Carbon
monoxide poisoning had a strong seasonality(M=0.77),with high incidence months of January,February and December(SI
were 3.60,3.08 and 2.48,respectively). The inpatients with chemical poisoning showed non-random distribution and spatial
correlation(all P<0.01),with a high-high clustering among 13 districts and counties in northern Guangdong(all P<0.05).
Conclusion The number of hospital admission cases of chemical poisoning showed an overall decreasing trend in Guangdong
Province from 2016 to 2020. The main types of poisoning were carbon monoxide poisoning,alcohol poisoning and organic
solvent poisoning. The spatial distribution of chemical poisoning types showed spatial correlation and there were high-high
clustering areas.

Objective To evaluate the results of using focus clearance and morselized bone graft to treat a well-fixed socket osteolysis after total hip arthroplasty (THA) during cementless acetabular revisions.Methods From March 2006 to March 2009, 23 patients (23 hips) who had an acetabular revision hip arthroplasty of well-fixed socket for osteolysis were retrospectively reviewed, including 13 males and 10 females with an average age of 46.6 years (range, 39-54), and the mean interval from primary to revision THA was 5.5 years (range, 4.6-7.4). The preoperative Harris hip score was 74. The operative technique included debridement of soft tissues with removal of granulomata and packed tightly with morselized cancellous allograft through ilioinguinal approach, and exchanging the liner and femoral head through the posterior-lateral approach of the hip. Results The mean duration of follow-up after revision was 28 months (range, 8-38). At final follow-up, all hip were functioning well and the average Harris hip score was 93.8. Osteogenesis in bone graft were well-developed in 16 patients. Twelve bone grafts were completely incorporated into surrounding bone through creeping substitution. All acetabular components remain radiographically well-fixed and no loosening and shifting. There were no new osteolytic lesions, ectopic ossification, deep venous thrombosis, hip dislocation or infection during follow-up. Conclusion Our revision strategies included debridement and bone grafting, a revision of femoral heads and polyethylene liner and retention of the cups and femoral stems. The method can reduce the amount of the wear particle from polyethylene. The short-term outcome is excellent.
