Objective :
To examine the association between intrinsic capacity and falls in older adults, so as to provide insights into the risk assessment of falls.
Methods:
Older adults aged 60 years and above were selected from two districts and one county in Bengbu City, Anhui Province from September 2022 to June 2023 using convenience sampling method. Demographic information, health-related behaviors and incidence of falls among participants were collected through questionnaire surveys. The intrinsic capacity included five dimensions: sensory, motor, vitality, cognition and psychology, which were investigated by the sensory dimension screening scale recommended by the World Health Organization, the Simple Physical Functioning Battery (SPPB), the Micro Nutritional Assessment Scale (MNAS-SF), the Brief Intelligent Mental State Examination Scale (MMSE), and the Center for Evaluation of Streamlined Depression Levels 10-entry scale (CESD-10), respectively. A total score of 1 or more indicated a decrease in intrinsic capacity. The association between intrinsic capacity and falls in older adults was analyzed by a multivariable logistic regression model.
Results:
A total of 1 950 questionnaires were allocated, and 1 917 were valid, with an effective rate of 98.30%. There were 934 men (48.72%) and 983 women (51.28%), with a mean age of (68.15±3.42) years. There were 1 352 rural residents (70.53%) and 1 431 illiterate and primary school-educated residents (74.65%). In the past year, 347 residents fell, accounting for 18.10%. The median comprehensive score for intrinsic capacity was 1.00 (interquartile range, 2.00) points, and 1 320 had a decrease in intrinsic capacity, accounting for 68.86%. Multivariable logistic regression analysis showed that decline in intrinsic ability was associated with the risk of falls after adjustment for age, gender, educational level, marital status, alcohol consumption and self-rated health status (OR=1.531, 95%CI: 1.408-1.721).
Conclusion
Decreased intrinsic capacity in older adults may contribute to an increased risk of falls.

OBJECTIVE:
To observe and summarize the abnormal morphological appearance of nasal septum tail during adenoidectomies, and to have a preliminary study on its clinical significance.
METHOD:
One hundred and eighty-three children were shown with abnormality on nasal septum tail in 2892 cases with adenoid hypertrophy who received adenoidectomies in our department.
RESULT:
The abnormalities of nasal septum tail can be classified into two types: del tails and columnar ones. All children suffered from nasal septum tail received radiofrequency ablation and all had a good postoperative recovery.
CONCLUSION
The presence of these two types of nasal septum tail may be related to adenoid hypertrophy, adenoiditis, sinusitis, and some congenital malformations.

Objective:
To investigate the association between self-rated health status and mortality risk, and to evaluate the predictive value of self-rated health status for mortality risk among the elderly.
Methods:
Based on the China Health and Retirement Longitudinal Study (CHARLS) database, data of sociodemographic information, self-rated health status and mortality of the elderly aged 60 years and older were collected from 2011 to 2018. The association between self-rated health status and mortality risk among the elderly was analyzed using a multivariable Cox proportional risk regression model.
Results:
Totally 4 850 individuals were included, with an median age of 65 (interquartile range, 8) years. There were 2 485 males (51.24%) and 2 365 females (48.76%). There were 877 individuals (18.08%) rated their health as good, 2 078 individuals (42.85%) as general, 1 895 individuals (39.07%) as poor. A total of 28 955 person-years were followed up, with an average follow-up of 5.97 years per person. There were 855 deaths by the end of follow-up in 2018, and the median survival time was 7 (interquartile range, 3) years. Multivariable Cox proportional risk regression analysis showed that there were interactive effects of age, sex and self-rated health status on mortality, respectively (both P<0.05). The results of gender-stratified analysis showed that there was no significant association between self-rated health status and mortality risk in old women (P>0.05). The mortality risk was higher in old men with poor self-rated health than with good self-rated health (<70 years, HR=5.382, 95%CI: 3.263-8.876; 70 to 79 years, HR=3.536, 95%CI: 1.070-11.686; ≥80 years, HR=3.043, 95%CI: 1.827-5.066).
Conclusion
There is an association between self-rated health status and mortality risk among the elderly, the old men with poor self-rated health had a higher mortality risk.

Objective To investigate the immunomodulatory effects of heme oxygenase-1 ( HO-1) modified rat bone marrow mesenchymal stem cells ( BM-MSCs) on lymphocytes .Methods Rat BM-MSCs were cultured and identified in vitro.HO-1 gene was transduced into BM-MSCs via recombinant adenovirus (rAdV) to construct HO-1/BM MSCs, which were then co-cultured with rat spleen lymphocytes .The cellu-lar activity of lymphocytes was detected by using MTT method .The cell cycle distributions were analyzed by propidium iodide staining and flow cytometry .ELISA was used to detect the level of cytokines in the super-natant of cultured cells .The expression of lymphocyte activation markers , CD25 and CD71, were measured by using fluorescence labeled antibodies and flow cytometry .Results Compared with the control group , the lymphocytes co-cultured with HO-1/BM MSCs showed a suppressed proliferation and cell cycle progression . HO-1/BM MSCs inhibited the secretion of IL-2, TNF-αand IFN-γ, but enhanced the secretion of IL-10 in lymphocytes.Furthermore, the expression of CD25 and CD71 were also down-regulated by HO-1/BM MSCs. Conclusion Compared with BM MSCs , HO-1/BM MSCs show higher immunosuppressive effects on lym-phocytes .

Objective:
To investigate the characteristics and trend of stroke incidence in Jining City, Shangdong Province from 2015 to 2022, so as to provide the reference for formulating prevention and control strategies of stroke.
Methods:
Data of stroke incidence in Jining City from 2015 to 2022 were collected from Shandong Provincial Chronic Disease Surveillance Information Management System. The crude incidence was estimated, standardized using the data of the sixth national population census in 2010, and analyzed by age, gender and subtype. The trend in incidence of stroke was analyzed using annual percent change (APC).
Results:
A total of 316 267 cases of stroke were reported in Jining City from 2015 to 2022, with a crude incidence of 474.17/105 and a standardized incidence of 371.43/105. The incidence of stroke peaked from March to May (90 409 cases, 28.59%). There were 278 901 cases of ischemic stroke (88.19%) and 37 366 cases of hemorrhagic stroke (11.81%). The crude incidence of stroke was higher in males than in females (525.45/105 vs. 420.16/105, P<0.05). The crude incidence of stroke increased with age (P<0.05), reaching a peak in the age group of 80 years and above (2 764.92/105). From 2015 to 2022, the crude incidence of stroke in the overall population, males, females, the age groups of 0-<30 years and 40-<50 years showed increasing trends (APC=6.142%, 6.992%, 5.054%, 3.693% and 6.587%, all P<0.05); the crude incidence of ischemic stroke in the overall population, males and females showed increasing trends (APC=7.489%, 6.593% and 5.456%, all P<0.05), while the crude incidence rates of hemorrhagic stroke did not show significant trends (APC=3.455%, 2.804% and 1.919%, all P>0.05).
Conclusions
The crude incidence of stroke increased in Jining City from 2015 to 2022, with ischemic stroke as the predominant subtype. March to May was the peak period for disease onset, and young and middle-aged men should be focused on.
