Objective: To investigate the clinicopathological features and immunophenotype of inflammatory myofibroblastic tumor (IMT) and their relationship with IMT diagnosis and prognosis. Methods:A total of 11 IMT cases with follow-up were analyzed morpho-logically and immunohistochemically. Results:The patients included 6 men and 5 women aged 13-66 years. The tumors were found in various anatomical sites, including lung, mediastinum, liver, intra-abdominal, and bladder. Histologically, the majority of the cases com-prised spindled fibroblastic and myofibrobalstic cells accompanied by chronic inflammatory cells in a myxoid or hyalinized stroma;the rest were individual cases of abscess formation. Prognosis mala was indicated for cases with features including atypia tumor cells with two cases demonstrating epithelioid morphology and nucleoli. Immunohistochemical study showed that vimentin, ALK, SMA, S-100, CD117, and CD34 were expressed in 91%(10/11), 55%(6/11), 100%(11/11), 27%(3/11), 18%(2/11), and 9%(1/11) of IMT, respective-ly. Ki-67 was expressed from 3%-40%respectively. CK, H-caldesmon, and DOG1 were negative in all cases. Follow-up data were avail-able for 11 patients and ranged from 4 to 22 months. Data showed that 7 patients were alive with no evidence of disease;4 patients were alive with tumor, whereas 3 showed aggressive biological behavior. Conclusion:IMTs had intermediate behavior or malignant po-tential. Most IMTs with aggressive behavior showed a minority of tumor cells with atypia, epithelioid morphology, and nucleoli. High proliferation index expression, ALK, SMA, and H-caldesmon can aid in IMT diagnosis.

Objective:To evaluate the reliability and validity of the Chinese version of behavioral activation for depression scale (C-BADS) in patients in methadone maintenance treatment (MMT).Methods:A total of 162 opioid addicts were recruited from the MMT programs in Wuhan city for the C-BADS investigation.Items analysis and exploratory factors analysis (EFA) were conducted with SPSS 21.0 and confirmatory factors analysis (CFA) was conducted with AMOS 24.0.Results:The correlation coefficients between subscales and total score were 0.228-0.813 (all P<0.01). Except for activation subscale, the correlation coefficients among subscales were lower than those between subscale dimensions and total score.The item-total score correlations coefficient were 0.060-0.716.Four factors were extracted by EFA, named avoidance/rumination(AR), activation(AC), social impairment(SI) and work/school impairment(WS) respectively, which the cumulative variance was 51.153%, and the factor loading of each item ranged from 0.328 to 0.797.The fitting indexes of CFA model were as following: χ 2/ df=1.594, CFI=0.839, TLI=0.820, IFI=0.844, RMSEA=0.069, SRMR=0.089.The Cronbach's α of the scale was 0.790, and the split-half reliability coefficient was 0.827. Conclusion:C-BADS has good internal consistency reliability and construct validity, but it still needs to be modified for the measurement of behavior activation of patients in MMT.

The elderly are the main body of people with sarcopenia which not only seriously affects the quality of life of the elderly, but also brings a heavy burden to the family and society.Maintaining and improving the function of the elderly and preventing the occurrence of sarcopenia in the elderly are the important measures in the health management of the elderly.In order to effectively carry out health education on sarcopenia in the elderly and to popularize relevant health care knowledge, the National Center of Gerontology and the Chinese Geriatrics Society have formulated the "Chinese expert consensus on the core information for the prevention of sarcopenia in the elderly(2021)" , relying on the expert team after several rounds of expert discussions.It provides scientific basis for the management and early intervention of sarcopenia.Let us now try to interpret the consensus on the key knowledge points of the core information sequence.

Objective:To analyze the process of Chinese expert consensus on the core information on prevention of sarcopenia in the elderly(2021)in China, so as to realize the early diagnosis and treatment of sarcopenia and to improve the quality of life in the elderly.Methods:The index system framework was established by literature review and expert questionnaire discussion, and Delphi expert consultation method was adopted to construct the index system.Results:A total of 109 experts(128 person-times)in Geriatrics from various fields participated in Delphi expert consultation.Positive coefficient for four rounds of expert consultation were 88.9%, 100.0%, 100.0% and 100.0% respectively, with expert authority factors being concentrated on 0.78~0.90.Through 4 rounds of Delphi expert surveys, the core information index system for sarcopenia prevention in the elderly has been definitive: Chinese Expert Consensus(2021)consists of nine indicators including "enhancing public scientific awareness of myosis, and so on."Conclusions:The core information index system for sarcopenia prevention in the elderly has high levels of overall convergence, comprehensive coverage, strong authority, stability, comprehensiveness and popularity.

Objective:To evaluate and analyze the health status of the elderly from physical health, mental health and social health, so as to understand the health status and health service needs of rural elderly.Methods:A total of 263 elderly people aged 60 years and over(mean aged 70.9±7.9 years, 113 males and 150 females, 125 aged 60-69 years, 98 aged 70-79 years and 40 aged 80 years and over)in Nanwangkong Village, Shaozhuang Town, Qingzhou City, Weifang City, Shandong Province were selected by cluster sampling method.The physical, mental, social and overall health status of the elderly were comprehensively evaluated and analyzed by self-designed questionnaire.Results:The overall health rate was 30%(79 cases), and the physical health, mental health and social health rates were 73.8%(194 cases), 84.0%(221 cases)and 34.6%(91 cases), respectively, in rural elderly in this area.The physical health was better in males than in females in 80~ years old groups( χ2=5.736, P<0.05). The overall health was better in males than in females in the total age group and the 60~69 years old groups( χ2=7.468 and 11.116, both P<0.01). The proportions of unhealthy, basic healthy and healthy people in the overall and the dimensions of physical health, mental health and social health had significant differences in the 60~69, 70~79 and 80~ years old groups( χ2=40.590, 29.342, 18.503 and 27.615, all P<0.01), and the Chi-square test for trend showed that there was a statistically significant downward trend of overall health grade distribution with age( χ2=21.994, 12.831, 16.570 and 22.595, both P<0.01). Conclusions:In this study, 30.0% of the rural elderly were considered healthy, 48.3% were basically healthy, and 21.7% were unhealthy.The health status of the elderly gradually deteriorates with age.The government should strengthen the multidimensional health assessment of the rural elderly and provide the comprehensive health guidance services and targeted interventions for the elderly in terms of disease control, psychological counseling and social participation.

Objective:To evaluate and analyze the health status of elderly people from the physical, psychological and social aspects using the Health Criteria for Older Adults in China(2022), and to understand the impact of social demographic characteristics on the overall health status of the elderly.Methods:159 elderly people aged 60 years and over in the Lanyuan community of Malianwa Subdistrict, Haidian District, Beijing were selected by the stratified sampling method, with a mean age of(70.7±7.9)years, including 74 men and 85 women.The physical, psychological, social and overall health status of the elderly were comprehensively evaluated and analyzed from data collected through a self-designed questionnaire with face-to-face interviews at respondents' homes.Results:The percentage of participants in this community who were considered overall healthy was 30.2%(n=48). The proportions of those meeting the criteria for physical, mental and social health were 79.2%(n=126), 90.6%(n=144)and 32.1%(n=51), respectively.For participants of 3 age groups(60-69, n=89; 70-79, n=44; ≥80, n=26), differences in percentages of people who were considered not healthy, largely healthy and healthy, measured using the overall, physical, mental and social health criteria, were statistically significant( χ2=24.683, 57.096, 12.801, 11.802, all P<0.05), and results of the χ2test for trend showed that the frequency distribution of people with overall, physical, mental and social health decreased with age( χ2=16.878, 31.600, 9.626, 9.626, all P<0.05). Multivariate Logistic regression analysis showed that education level( OR=2.142, 95% CI: 1.053-4.538, P=0.035)was an influencing factor for overall health status of the elderly. Conclusions:The overall health status of community-dwelling elderly people in Beijing is relatively poor and deteriorates with age.Education level is a factor affecting their health status.Health assessment for the elderly should be strongly advocated, and targeted health education should be provided for the elderly in disease prevention and mental health care.
