ABSTRACT
BACKGROUND: Olecranon fracture-dislocations are complicated fractures and dislocations of the elbow, which adds certain challenges to clinical diagnosis and treatment. Although the continuous improvement of medical standards has made some progress in the clinical diagnosis and treatment of olecranon fracture-dislocations, some controversial issues need to further discuss. OBJECTIVE: To consult and sort out the relevant literature about the clinical diagnosis and treatment of olecranon fracture-dislocations, and give a summary. METHODS: The first author searched the relevant documents collected by Web of Science, PubMed and CNKI databases from 2000 to 2020. The key words were “olecranon; elbow; fracture dislocation; 3D printing” in English and Chinese. The massive relevant literature was reviewed and collected. The literature was classified and analyzed from the aspects of anatomical mechanics, injury characteristics, diagnostic typing and surgical treatment. RESULTS AND CONCLUSION: (1) The anatomy of the olecranon, coronoid process, radial head, and the anatomical mechanical characteristics between the soft tissues affect the clinical diagnosis and treatment of olecranon fracture-dislocations. (2) Both anterior and posterior dislocations have their own injury characteristics and are easily confused with Monteggia fractures. Accurate grasp of physical examination and auxiliary imaging examination is conducive to clinical diagnosis. (3) The posterior midline approach is more commonly used, and other approaches should be combined if necessary. Proper fixation and repair of bone and soft tissue, as well as timely auxiliary external fixator, are conducive to improving the clinical efficacy of olecranon fracture-dislocations. (4) However, the damage mechanism of the rear olecranon fracture-dislocations needs to be further explored, and whether to establish independent classification of olecranon fracture-dislocations needs further discussion. The effectiveness of the indirect fixation of the coronoid process behind the olecranon still needs further research. (5) In addition, the emerging three-dimensional printing technology is of great significance for preoperative planning and simulation of bone trauma, and will be more conducive to the development of clinical diagnosis and treatment of olecranon fracture-dislocations.
ABSTRACT
Objective@#To investigate the demand and access to the cancer prevention and treatment knowledge and related factors among urban residents in China from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of general demographic characteristics, the demand and access to cancer prevention and treatment knowledge, and the influencing factors of the attitude. The Chi-square test was used to analyze the difference of the demand of the cancer prevention knowledge among different groups and the corresponding factors of the cancer prevention and treatment knowledge were analyzed by using the logistic regression model.@*Results@#The proportion of residents who need the cancer prevention and treatment knowledge was 79.5%. The demand rate of the inducement, symptom and diagnosis methods of cancer in the occupational population was highest, about 66.8%, 71.0% and 20.8%, respectively. The demand rate of treatment methods and cost in current cancer patients was the highest, about the 45.9% and 21.9%, respectively. The top three sources to acquire the cancer prevention and treatment knowledge were "broadcast or television" (69.5%), "books, newspapers, posters or brochures" (44.7%) and "family and friends" (33.8%). The multivariate analysis showed that compared with public institution personnel/civil servants, unmarried/cohabiting/divorced/widowed and others, annual household income less than 20 000 CNY, from the eastern region, people without cancer diagnosis and people with self-assessment of cancer risk, the demand rate of cancer prevention and treatment knowledge was higher in enterprise personnel/workers, married, annual household income between 60 000 CNY and 150 000 CNY, from the central region, people with cancer and people with unclear cancer risk (all P values <0.05).@*Conclusion@#There was a high demand for the cancer prevention and treatment knowledge among urban residents in China from 2015 to 2017. The main access to the knowledge is from the radio or television. The occupation, marital status, annual household income, residential region, health status and risk of disease were the main factors of the demand of the cancer prevention and treatment knowledge.
ABSTRACT
Objective@#To understand the health literacy of the cancer prevention and treatment among urban residents of China, and explore the related factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The health literacy of the cancer prevention, early discovery, early diagnosis, early treatment and the demands of cancer prevention and treatment knowledge was analyzed. The level of health literacy among different groups were calculated and compared. The binary logistic regression model was used to analyze the influencing factors of the health literacy of the cancer prevention and treatment.@*Results@#The level of health literacy of the cancer prevention and treatment was 56.97% among all study population; in each group it was 55.01% for community residents, 59.08% for cancer risk assessment/screening population, 61.99% for cancer patients and 57.31% for occupational population, respectively (P<0.001). The level of health literacy of the cancer prevention and treatment of residents aged 50 to 69 years old, other occupational groups, unmarried, the central and western region residents and the group with unclear self-assessment of cancer risk was significantly lower than that of residents younger than 40 years old, personnel of public institutions/civil servants, married, the eastern region residents and the group whose self-assessment without cancer risk (P<0.05) . The level of health literacy of cancer prevention and treatment of females, people who went to high school or over, cancer risk assessment/screening population, cancer patients and occupational population was significantly higher than that of males, people who had an education level of primary school or below and community residents (P<0.05) .@*Conclusion@#The health literacy of the cancer prevention and treatment of urban residents in China was relatively high, but there was still room for improvement. Gender, age, educational level, occupation, region, marital status, self-assessment of cancer risk, and type of respondents were the key influencing factors of the health literacy of the cancer prevention and treatment. Male, 50-69 years old, lower educational level, central and western regions, unclear cancer risk self-assessment, and without specific environmental exposure to cancer prevention and treatment knowledge or related risk factors were the characteristics of the key intervention group of the health literacy of the cancer prevention and treatment.
ABSTRACT
Objective@#To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment.@*Results@#With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05).@*Conclusion@#Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.
ABSTRACT
Objective@#To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis.@*Results@#As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05).@*Conclusions@#From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years.@*Results@#The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05).@*Conclusion@#From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

Objective@#To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors.@*Results@#The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05).@*Conclusion@#The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.

ABSTRACT
The phagocytosis of opsonic chicken erythrocytes which were engulfed byMMC-1 cells was studied by means of transmission electron microscopy.After incu-bating chicken erythrocytes with the serum of rabbit-anti chicken antibody.MMC-1cells were surrounded by 1 to more than 10 opsonized erythrocytes.The EA rosetteswere formed.At first,opsonized erythrocytes attached to the MMC-1 cells in somepoints.At the site of interaction of opsonized erythrocytes with MMC-1 cells theelectron dense bands which were the specialization of the MMC-1 cell plasma mem-brane appeared.Then many projections of the erythrocytes were engulfed intoMMC-1 cells.When part of the erythrocyte was engulfed by macrophage,a collar-like structure arround the erythrocyte could be seen.Partially engulfed erythrocyteslooked like a dumbbell.The engulfed erythrocytes were irregular in shape.Thedensity of engulfed erythrocytes became faint gradually.The round ring with highelectron density appeared and enlarged in erythrocytes.It was shown that the opso-nized erythrocytes which formed EA rosettes were engulfed by MMC-1 phagocyte.After engulfing many erythrocytes,MMC-1 cells might degenerated or be engulfedby other MMC-1 cells.It was proved that Fc receptors presented on MMC-1 cells.Many mitochondria were easily found in MMC-1 cells,they were responsible forenergy supplies.Extruding of engulfed nuclei from macrophage could be seen too.It was shown that MMC-1 cells had the characteristics of macrophage and it wasestablished by cell fusion of phagocyte and thymoma cell.
ABSTRACT
The fine structure of MMC-1 mouse macrophage-like cells was studied by means of electron microscopy. Electron micrographs of these macrophages revealed dark cells, light cells and empty cells according to their density. These three cell types could also be found in other cultural cell lines.The dark cells had the highest electron density. They were round, elliptical or spindle-like in shape and many protrusions were observed on the cell surface. The endoplasm and ectoplasm could be divided clearly. There Were no organelles in the latter. In the endoplasm mitochondria, rough endoplasmic reticulum and polyribosome were abundant, lysosomes, Golgi complexes and microfilaments were easily found. Nucleus with irregular shape located in one side of the cell, euchromatins were prominent, and nucleoli appeared in some cells. Light cells had less cytoplasmic processes, dilated mitochondria, abundant lysosomes, fat droplets and dilated nuclei. Empty cells had only a little cytoplasmic processes, less endoplasmic reticulum and a lot of primary and secondary lysosomes. Sparse chromatins were distributed in the dilated nucleus.According to these fine structures and the origin of this cell line the name of the macrophage-like cell line was suggested.
