【Objective】 To clarify the concept of health literacy among children and adolescents with accidental injuries through literature review and analysis. 【Methods】 A systematic search was conducted across multiple databases, including China National Knowledge Infrastructure, Wanfang database, VIP database, China Biomedical literature database, PubMed, CINAHL, and PscyINFO database. The literature was analyzed using Rodgers′ evolutionary concept analysis method. 【Results】 A total of 56 articles were included. The health literacy of children and adolescents with accidental injuries comprised three conceptual attributes:cognition, emotion and behavior. The influencing factors included children′s demographic factors, family and school related factors and social related factors. The result can be beneficial to reduce the occurrence of injury events, save family economic expenditure and alleviate the burden on social medical resources. However, there is currently a lack of specific measurement tools for assessing health literacy in this population, as the existing evaluation items are drawn from general health literacy scales. 【Conclusions】 The concept of health literacy among children and adolescents with accidental injuries is multifaceted and evolving. Future research should focus on exploring the characteristics of health literacy among children and adolescents of different ages and regions from their own perspectives. Additionally, efforts should be made to refine the concept and develop specialized measurement tools to facilitate further studies in this area.

BACKGROUND: Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting. METHODS: To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks. RESULTS: A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor. CONCLUSIONS Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Objective To investigate the effects of Osteoking on hyperglycemia and regulating gut microbiota in db/db mice.Methods Wildtype mice were used as the control group,and db/db mice were randomly divided into model and Osteoking groups.After intragastric administration for 12 weeks,fasting blood glucose and serum glycosylated hemoglobin and insulin levels were measured,changes in intestinal microflora were determined,and functional pathways related to intestinal microflora in mice were predicted by 16S rDNA sequencing.Results Compared with the model group,Osteoking decreased fasting blood glucose(P<0.01),serum glycosylated hemoglobin(P<0.01),and the insulin resistance index(P<0.01),and increased insulin content(P<0.01)in db/db mice.Osteoking increased the abundance of beneficial intestinal microflora and decreased the abundance of harmful bacteria.Moreover,the abundance of Marvinbryantia was increased.Osteoking alleviated the decrease in metabolism of D-arginine and D-ornithine,sphingolipid,and galactose metabolism(P<0.05)and inhibited lysine degradation,the sulfur relay system,and propanoate metabolism(P<0.05).Conclusions Osteoking has hypoglycemic properties and improves the intestinal microflora imbalance in db/db mice.

Objective:To investigate the risk factors for biochemical recurrence after radical prostatectomy.Methods:The clinical data of 558 radical prostatectomy patients admitted to the First Affiliated Hospital of Air Force Military Medical University from January 2010 to December 2020 were retrospectively analyzed. The average age was 67.9 (40-87) years old, and the average body mass index was 24.56 (15.12-35.94) kg/m 2. The average PSA was 41.07 ng/ml, including 48 cases<10 ng/ml, 98 cases 10-20 ng/ml, and 412 cases>20 ng/ml. There were 123, 214, 118, 89, and 14 cases with biopsy Gleason 6-10 score, respectively. The clinical stage : 90 cases in ≤T 2b, 273 cases in T 2c, and 195 cases in ≥T 3 . 558 cases underwent radical prostatectomy, including 528 robotic-assisted laparoscopic surgery, 25 laparoscopic surgery, and 5 open-surgery. The risk factors for postoperative biochemical recurrence were analyzed by Cox regression. Results:A total of 63 patients had postoperative pathological stage pT 2a, 32 patients had pT 2b, 241 patients had pT 2c, and 222 patients had ≥pT 3. A total of 210 cases developed biochemical recurrence after surgery, and the mean time to biochemical recurrence was 33.3 (3-127) months after the radical prostatectomy. The biochemical recurrence rates at 1, 3, and 5 years were 9.7% (54/558), 21.5% (120/558), and 31.7% (177/558), respectively. Among pT 2a and pT 2b patients, 7 (11.1%) and 4 (12.5%) cases developed biochemical recurrence, respectively. Among pT 2c stage patients, 145 (60.17%) cases had positive cut margins, treated with androgen-deprivation therapy (ADT) after surgery. 68 (28.21%) cases of pT 2c stage patients had biochemical recurrence at mean 36.1 (3-106)months after the radical prostatectomy. Among ≥pT 3 patients, 147 patients with positive margins, perineural invasion, seminal vesicle invasion and positive pelvic lymph nodes were treated with postoperative androgen deprivation therapy (ADT) + radiotherapy. 98 of 147 patients (66.67%) had biochemical recurrence, and the average time to biochemical recurrence was 30.6 (24-98) months.75 patients of ≥pT 3 without positive margins, perineural invasion, seminal vesicle invasion or positive pelvic lymph nodes, were treated with postoperative ADT. 33 of them (44%) had biochemical recurrence, and the average time to biochemical recurrence was 32.5 (21-106) months. 5-and 10-year survival rates of 210 patients with biochemical recurrence were 89.05% (187/210) and 78.09% (164/210) respectively, 5- and 10-year tumor-specific survival rates were 92.57% and 87.69%, respectively. 46 of 210 cases died, of which 31 (67.39%) died from prostate cancer, and 15 cases (32.61%) died from cardiovascular and cerebrovascular diseases. Multifactorial Cox regression analysis showed that patient's age ≥70 years, initial PSA > 20ng/ml, ≥pT 3 and Gleason score ≥7 were independent risk factors for biochemical recurrence. Conclusions:After radical prostatectomy, patients were treated according to their pathological stage and surgical margins. Patients with positive margins have a higher risk of biochemical recurrence. The independent risk factors for biochemical recurrence included age ≥70 years, initial PSA > 20ng/ml, ≥pT 3 and Gleason score ≥7.

Objective: To explore the independent predictors for disease-specific survival (DSS) rate in patients with stage N_1-3 testicular seminoma (TS), and establish a nomogram to predict individual 5-year DSS. Methods: The data of N_1-3 TS patients registered in the SEER database of National Cancer Institute (USA) from January 2004 to December 2015 were retrospectively analyzed. The 5-year overall survival (OS) rate and DSS rate were calculated using Kaplan-Meier method and the differences among different subgroups were assessed using log-rank test. Besides, the independent predictors of DSS were defined using multivariate Cox regression analysis, and nomogram was drawn using R software. Furthermore, the predictive performance of the nomogram was internally validated using the C-index and calibration plot. Results: TNM stage ⅢA (HR=5.604, 95%CI: 1.252-25.083, P=0.024), ⅢB (HR=6.710, 95%CI: 1.923-23.410, P=0.003) and ⅢC (HR=13.189, 95%CI: 3.916-44.420, P<0.001), age at diagnosis ≥45 years old (HR=3.575, 95%CI: 2.014-6.344, P<0.001), and patients without spouse (HR=2.346, 95%CI: 1.406-3.914, P=0.001) were identified as independent risk factors for DSS. On internal validation, the predictive accuracy of our nomogram was 0.751 (C-index: 0.751, 95%CI: 0.694-0.808). Besides, the calibration plot showed that the predicted survival outcomes were highly consistent with the actual survival outcomes. Conclusion The study confirms that age at diagnosis ≥45 years old, TNM stage ≥ⅢA and patients without spouse are the independent risk factors for DSS in TS patients with stage N_1-3, and the nomogram for predicting individual 5-year DSS is established.

Objective To establish a tree shrew mode of breast tumor.Method Forty-five 3 to 4 month-old female tree shrews were orally gavaged with 20 mg 7,12-dimethylbenz(a)anthracene (DMBA) or peanut oil per animal for three times.Following that, fifteen DMBA administrated tree shrews were implanted 90 day-release medroxyprogesterone acetate ( MPA) pellets.The tree shrews were palpated once weekly to detect mammary tumors for 45 weeks after first DMBA administration.Results DMBA were able to induce breast tumors (12.5%) in tree shrews, and MPA increased the tumor incidence (50%) while no breast tumors were observed in the control group.Three induced breast tumors were intraductal papillary carcinomas and one was IDC by H&E stain.Conclusion All induced tumors are similar with spontaneous tumors in structure and molecular markers.

Objective To analyze the neuroimaging changes of tree shrew models of Alzheimer’ s disease.Methods Nineteen healthy adult female tree shrews were randomly divided into control (5 animals) and model group (14 animals). The model of Alzheimer’s disease was induced by intracerebroventricular injection of Aβ1-40 using a stereotaxic devise and proved successfully by visuospatial congnitive task.The in vivo microstructural changes in the brain of tree shrew AD models and control group (0, 1, 2, 3, 4 weeks) were observed on 1.5T MRI (T2WI), and on 7.0T MRI (12 week)(T2WI, DTI). Results Reference memory errors were increased in the model group at 3 or 4 weeks (P<0.05), and so working memory errors (P<0.05) and period of time to perform (P<0.05, P<0.05, P<0.01) from 2 to 4 weeks.Thus the model was proved to be established successfully.T2WI test and DTI test were carried out.Hippocampus atrophy of the model group at 3 and 4 weeks was observed compared with that at 0 or 1 week or 2 weeks on a 1.5T Philips Gyroscan.Compared with the control group, the temporal horn width in the model group was significantly increased (P<0.01) at 12 weeks on a 7.0T Bruker Biospec Scanner.DTI test at 12 weeks showed that ADC of bilateral hippocampus was up-regulated in the model group ( P<0.01 ) .In the color coded orientation view, loss of the corpus callosum fibers was obvious in the model group. Conclusions Intracerebroventricular injection of Aβ1-40 can lead to learing and memory impairment in tree shrews.There are abnomal MRI signal changes in the brain, and the temporal horn width, hypocampal apparent diffusion coefficient ( ADC) value and corpus callosum damage may provide reference value for the diagnosis of Alzheimer’ s disease.

Objective To investigate the expression levels of BDNF, trkB and ChAT mRNA and proteins in the brain of adult tree shrews ( Tupaia belangeri ) .Methods Quantitative real-time PCR was employed to detect the expression levels of BDNF, trkB and ChAT mRNA in the hippocampus, basal ganglia and frontal cortex of adult tree shrews.The expression levels of BDNF, trkB and ChAT proteins andβ-actin was used as internal standard.Results The expression level of BDNF mRNA was highest in the hippocampus of adult tree shrew, and there were significant differences between that in the hippocampus, and basal ganglia and frontal cortex (P<0.01).The expression level of trkB mRNA was higher in the frontal cortex than in the basal ganglia and hippocampus, showing a significant difference between them ( P<0.05).The expression level of BDNF protein was significantly higher in the basal ganglia than in the hippocampus or frontal cortex (P<0.01).There were no significant difference (P>0.05) in the expressions of trkB protein among the hippocampus, basal ganglia and frontal cortex of the adult tree shrews.There were no significant differences in expressions of ChAT mRNA and protein among the hippocampus, basal ganglia and frontal cortex in adult tree shrews ( P>0.05 ) . Conclusions The expression levels of ChAT mRNA were consistent with that of ChAT protein in the hippocampus, basal ganglia and frontal cortex of adult tree shrews, while the expression levels of BDNF and trkB mRNA were not consistent with their proteins, which might indicate that the transcriptional regulation pattern might be more complex.Tree shrew is a valuable animal model in the study of mechanism of BDNF/trkB gene expression.

Ponseti clubfoot treatment has become more popular during the last decade because of its high initial correction rate. But the most common problem affecting the long-term successful outcome is relapse of the deformity. Non-compliance with Ponseti brace protocol is a major problem associated with relapse. Although more comfortable braces have been reported to improve the compliance, they all have the same design and no significant changes have been made to the protocols. After refinement in the Ponseti method and emphasizing the importance of brace to parents, the relapse rate has been markedly decreased. Nevertheless, there are patients who do not have any recurrence although they are not completely compliant with the brace treatment, whereas other patients have a recurrence even though they are strictly compliant with the brace treatment. The aim of this article is to review the relapse of clubfoot and the function of the brace and to develop an individualized brace protocol for each patient by analyzing the mechanism of the brace and the biomechanical properties of muscles, tendons, and ligaments.
