As China enters the aging era, the incidence rate and prevalence of inflammatory bowel disease(IBD)in the elderly have increased.The relationship between aging and inflammation appears to be more significant in elderly individuals with IBD.However, most current studies focus on describing the clinical characteristics of the disease, with limited research on its pathogenesis and treatment.In this review, we summarize the differences in clinical characteristics and treatment between elderly individuals with IBD and young individuals.We also discuss the impact of aging on elderly IBD and explore the possibility of stem cell transplantation therapy as a new approach for clinical management.Our aim is to provide fresh insights for the treatment of elderly IBD.

ObjectiveTo observe the effect of twelve-week aerobic exercise on inhibitory control abilities and the change of brain activation in overweight children. MethodsFrom October to December, 2021, 20 overweight children from a primary school in Changping District were selected for a twelve-week aerobic exercise intervention. Their inhibitory control abilities were measured by Flanker task before and after intervention, while their brain activation levels during the task were detected by functional near infrared spectroscopy (fNIRS). ResultsThe interactions between task type and time of accuracy and reaction time in inconsistent tasks Flanker task were significant (F > 9.277, P < 0.05), with higher accuracy and lower reaction time of after intervention (P < 0.05). After intervention, ch1, ch2, ch3, ch6, and ch8 channels were activated by inconsistent tasks (P < 0.05). ConclusionA twelve-week aerobic exercise intervention could improve the inhibitory control ability, and increase the prefrontal cortex activation during inconsistent tasks in overweight children.

Objective To explore the affect of physical activity on neurocognitive function of overweight children.Methods The literatures about the effect of physical activity on neurocognitive function of overweight children were retrieved with subjected retrieval method in CNKI, VIP, Wanfang database, PubMed, Web of Science, EBSCO databases from January, 2000 to January, 2022. The authors, countries, published years, ages of subjects, research methods, intervention time, measurement tools and measurement indicators were extracted.Results Twelve articles were selected finally. These articles came from United States, Italy, Belgium and China, were mainly published in journals of psychology, clinical medicine, neuroscience, physical education. The study design included randomized controlled trials and pre-post-trial. The mean PEDro score was 6.67. The types of physical activity included fitness, skills and sports activities. The overweight children participating in physical activities could benefit from cognition and brain plasticity. On the cognition, physical activity could improve attention, memory, inhibitory control, working memory and cognitive flexibility. In terms of brain plasticity, physical activity could improve the integrity of brain white matter, increase hippocampal volume, enhance brain activation and brain network connectivity.Conclusion Physical activity is a simple and effective form of exercise. It can improve not only attention, memory, executive function and other cognitive functions, but also brain structure and brain function in overweight children. The mechanism of cognition, the interaction between physical activity and other factors, and the dose-relationship between physical activity and cognitive benefits still need to be explored in the future.

To construct cellular senescence model by stimulating primary hepatocytes with hydrogen peroxide (H 2O 2). Primary hepatocytes were transfected with p53 siRNA, progerin siRNA or IGF-1 adenovirus vector. The number of SA-β-Gal stained positive cells and the expression of p53 and progerin were detected. The results showed that p53 siRNA and progerin siRNA had knocked-down the expression of p53 and progerin, and had alleviated the hepatocyte senescence. Transfection of insulin-like growth factor (IGF)-1 adenovirus vector into primary hepatocytes had overexpressed IGF-1, and had alleviated the number of SA-β-Gal-positive cells. The expression of p53 and progerin was down-regulated in the nucleus, while the expression of p53 was up-regulated in the cytoplasm. The co-precipitation and co-localization of p53 and progerin was decreased in the nuclear region of hepatocytes. IGF-1 overexpression can inhibit intranuclear p53 translocation, alleviate the interaction between p53-progerin, and alleviate hepatocyte senescence.

Objective:A multi-center and large sample volume study was conducted on the verification and improvement of the early established criteria for intelligent routine urinalysis validation (including the microscopic review rules and manual validation rules, referred to as intelligent criteria for short), in order to improve the clinical application of this intelligent criteria.Methods:A total of 31 456 urine specimens were collected from the inpatients and outpatients in six hospitals in China, from March to September 2019. Firstly, 3105 specimens were analyzed for preliminary verification and improvement of the intelligent criteria based on the results of the microscopic examination and manual validation. Secondly, 28 351 specimens were used to verify the clinical application of the improved intelligent criteria. All samples were manually validated as reference.Results:The approval inconsistency rate of the manual validation rules in the original intelligent criteria was 8.59% (202/2 352), and the interception inconsistency rate was 8.84% (208/2 352). The false negative rate and the microscopic review rate of the microscopic review rules were similar to the previous results. Based on an in-depth analysis of big data and the discussions by senior technicians from eight hospitals, one microscopic review rules and four manual validation rules were added, meanwhile two manual validation rule was deleted. The manual validation standards were unified. Finally, the intelligent criteria was improved. Based on the improved intelligent criteria, for microscopic review rules, the false positive rate, false negative rate (misdiagnosis rate), and microscopic review rate did not change significantly, which were 14.72% (457/3 105), 4.06% (126/3 105), and 24.73% (768/3 105), respectively. The approval inconsistency rate and the interception inconsistency rate of manual validation rules were both reduced to 0; the total manual validation rate of the intelligent criteria was 50.89% (1 580/3 105), and the auto-validation rate was 49.11% (1 525/3 105). The large sample volume verification results were consistent with the preliminary verification results of the improved intelligent criteria.Conclusion:This multi-center and large sample volume study had shown that the improved intelligent criteria had better clinical performance.

Objective: To investigate the development of hepatocyte senescence during liver fibrogenesis and to explore the effect and possible mechanism of insulin-like growth factor 1 (IGF-1) on hepatocyte senescence and liver fibrosis. Methods: A total of 42 male Sprague Dawley (SD) rats were selected. Eighteen rats were induced by carbon tetrachloride (CCl₄) to establish the rat model of liver fibrosis. On the day 0, six and 28 after the establishment of the model, six rats were executed respectively to analyze the liver fibrosis and hepatocyte senescence in CCl₄-induced liver fibrosis rat models. Twenty-four rats were divided into control group, CCl₄ group, CCl₄+ lentivirus vector (LV-CTR) group and CCl₄+ LV-IGF-1 group, with six rats in each group.The rats were sacrificed on the 28th day after the establishment of the model. The liver tissues were obtained and the inferior vena cava blood was collected to analyze the effect of IGF-1 overexpression on liver fibrosis and hepatocyte senescence. Analysis variance (ANOVA), least significant difference (LSD) and Dunnett T3 test were performed for statistical analysis. Results: Steatohepatitis on the 6th day and early stage of hepatic fibrosis on the 28th day, which indicated the model was successfully established. The results of the effects of IGF-1 overexpression on hepatic fibrosis and hepatocyte senescence showed that on the 28th day, compared with those of control group, both the score of Ishak liver inflammation and necrosis and the score of Ishak liver fibrosis were increased in the CCl₄ group, CCl₄+ LV-CTR group and CCl₄+ LV-IGF-1 group (0, 14.55±1.94, 15.43±2.19 and 10.29±1.47, respectively; 0, 3.51±0.51, 3.21±0.79 and 1.32±0.40, respectively). The area of liver tissues by Masson staining (0.45±0.40, 5.62±1.08, 6.03±0.65 and 2.88±1.54), SA-β-Gal staining (1.75±0.80, 4.28±1.19, 4.92±1.14, 3.11±0.79), p53 (2.02±0.81, 4.36±1.02, 4.72±0.72 and 3.58±0.70) and progerin (0.72±0.40, 4.52±1.01, 4.01±1.25 and 2.66±0.80) all were increased. The levels of serum IGF-1 all were decreased ((632.00±6.04), (503.00±40.42), (508.00±21.94) and (572.40±5.94) ng/L). However the levels of ALT all were increased ((11.20±5.97), (214.00±73.90), (245.00±76.06) and (30.00±5.00) U/L). The relative expression levels of p53 (0.58±0.06, 1.78±0.18, 1.72±0.10 and 1.23±0.22) and progerin (0.12±0.02, 0.78±0.15, 1.32±0.20 and 0.81±0.16) in the primary hepatocytes were increased. The differences were all statistically significant (F=91.674, 90.778, 32.982, 9.726, 10.640, 17.029, 103.910, 30.059, 64.707 and 97.457, all P<0.05). Compared with those of CCl₄+ LV-CTR group, the score of Ishak liver inflammation and necrosis and the score of Ishak liver fibrosis were decreased in the rats′ liver tissues of CCl₄+ LV-IGF-1 group, the areas of Masson staining, SA-β-Gal staining, p53 and progerin in the liver tissues were decreased, the level of serum IGF-1 was increased, the level of ALT was decreased, and the relative expression levels of p53 and progerin in primary hepatocytes both were decreased. The differences were all statistically significant (all P<0.05, respectively). Conclusions Hepatocyte senescence increases in the process of liver fibrosis induced by CCl₄. Overexpression of IGF-1 may alleviate liver injury, improve hepatocyte senescence and liver fibrogenesis by regulating the nuclear p53/progerin pathway.
