Objective To study the influence of sole massage on children’s analepsia from general anesthesia.Methods One hundred children in analepsia period were divided into the test group(50 cases)and the control group(50 cases).The routine nursing and monitoring during recovery stage were done in the control group.Based on the routine monitoring and nursing care as in the control group,the test group received sole massage for 10 minutes.The two groups were compared in terms of declining percentage of SpO2, rate of nausea,blood pressure,heart-rate variability,and post-analepsia dysphoria scores.Result The test group was significantly lower than the control one in all the indexes of the declining percentage of SpO2,rate of nausea,blood pressure,heart-rate variability,and post-analepsia dysphoria scores(all P<0.05).Conclusions Sole massage during children’s analepsia from general anesthesia is effective not only in lessening their declining percentage of SpO2,rate of nausea,blood pressure,heart-rate variability, and recovery dysphoria mark,but also easing their dysphoria,anxiety and fear.It may create a good condition for children to live through analepsia period successfully and safely.

Objective Serum uric acid (SUA) levels have been identified to be associated with nonalcoholic fatty liver disease (NAFLD) which is often closely linked to obesity. However, few studies have examined the relationship between SUA levels and NAFLD in normal body mass index (BMI) people in whom NAFLD is noted not uncommon. We conducted this study to assess the association of SUA with NAFLD in Chinese normal-BMI people. Methods A total of 2 193 normal-BMI people (1 106 men and 1087 women) who participated in a health check-up were enrolled in this cross-sectional study. NAFLD was defined as a hepatic steatosis examined by liver ultrasonography in the absence of a second cause. Multiple regression analysis was performed to examine the relationship between SUA and NAFLD. Results Compared with people without NAFLD, those with NAFLD had significantly higher level of serum uric acid [males,(339.0±47.6)μmol/L vs.(309.3±53.5)μmol/L, t=3.296, P<0.01;female,(273.6±41.6)μmol/L vs. (243.9 ± 47.6)μmol/L, t=3.178, P<0.01]. Multiple regression analysis revealed that the quartile 3 and 4 of SUA in both sexes had a higher (P<0.05) odds ratio for the presence of NAFLD than the lowest quartile [males,odds ratio:2.508(1.255-3.374)and 3.383(2.058-5.490);females,odds ratio:2.186(1.090-4.384) and 2.420(1.214-4.821),respectively],after adjusting for age, body mass index, blood urea nitrogen, serum creatinine, the liver-function test, metabolic components, high sensitivity C-reactive protein, and smoking status.Conclusions Increased SUA level, even within the normal range, are independently associated with the presence of NAFLD among normal-BMI people.

Aim To establish a cell model targeting on GLP-1 R,and evaluate its function by the cAMP assay,for screening the new class of GLP-1 analogues as anti-diabetic candidates. Methods An eukaryotic expression vector pEGFP-GLP-1 R was constructed and transfected into HEK293A cells.After selecting with G41 8,a cell line stably expressing GLP-1 R-GFP was estab-lished.The expression and the cellular distribution of GLP-1 R-GFP fusion protein were investigated by Western blot and fluo-rescence microscopy.Then,the activity of GLP-1 analogue Lira-glutide was evaluated by monitoring the content of cAMP via HTRF using this cell model.Results GLP-1 R-GFP-293A cell line was successfully established.GLP-1 R-GFP fusion proteins were mainly distributed in the cell membrane.The dose-respon-sive relationship experiments revealed that cAMP could be effec-tively stimulated by Liraglutide using this cell model.Conclu-sion This cell model could be used to detect the bioactivity of GLP-1 analogues in vitro,which lays a foundation for the screen-ing of GLP-1 analogues and small GLP-1 R agonists.

Objective To study inhibitory effect of serine protease activity by Ulinastatin in vitro .Methods Different chromogenic peptides were designed and synthesized.Highly sensitive fluorescence detection was performed to optimize the concentration of each serine proteases and their chromogenic substrates.Multi-point method was used for the calculation of half maximal inhibitory concentration of Ulinastatin .ResuIts Ulinastain could inhibit Polymorphonuclear leukocyte elastase ( PMNE ) and plasmin with IC50 lower than 100 U/mL.For factor Xa, and Kallikrein, the IC50 of Ulinastatin was higher than 1000U/mL.No thrombin IC50 could be calculated at the present experiments.ConcIusion Similar to Ulinastatin injection from Japan, domestic Ulinastatin shows the strongest inhibitory effects on PMNE among those serine proteases.As important references, this study gives reliable data for dose range of domestic Ulinastatin in anti-inflammation, coagulation/anti-coagulation and anti-shock therapy.

Objective: To explore the influence of self-determination theory (SDT) on adolescent physical activity promotion. Methods: Six electronic databases including EBSCO host, Science Direct, Sports Discus, Springer Link, Pubmed, and Web of Science. The search period is from all databases to all relevant documents from the start date to May 18, 2019. An exhaustive collection of studies was selected to assess the relationship between motivation and physical activity in children and adolescents. Results: A total of 41 studies met the inclusion criteria. The overall level of self-determination motivation had a weak to moderate promotion of physical activity level (ρ=0.21-0.31). Autonomous forms of motivation (internal motivation and identification regulation) had a moderate role in promoting physical activity(ρ=0.27-0.38), while controlled forms of motivation (ie, introversion regulation and external motivation) had weak inhibition(ρ=-0.17--0.03). Lack of motivation showed a weak inhibitory effect on physical activity(ρ=-0.21--0.11). Conclusion Self-determination motives are significatly correlated with continued health promotion behaviors. Therefore, it is an effective method to promote physical health among children and adolescents with self-determination motive as an objective in the intervention.

Objective: To investigate the effect of gross motor skills on physical activity of children aged 3-6 years, and to provide basis for children’s health behavior intervention. Methods: A total of 332 young children in Shanghai Xiangyin kindergarten were selected as survey objects. The development of gross movements of young children was measured by TGMD-2. Caregivers reported children’s physical activity using the International Physical Activity Questionnaire (IPAQ-SF). Results: The development level of gross movements of children aged 3-6 in Shanghai was relatively low(54.76±13.86). The physical activity of children was mainly light-intensity physical activity, and the daily moderate-to-vigorous intensity physical activity time was (58.62±52.73) minutes every day. Locomotor skills had the greatest effect on children’s VPA (β=0.19) and TPA(β=0.12), with a contribution rate of 3.3% and 1.1%, respectively; Object control skills has the greatest effect on children’s MVPA (β=0.17) and MPA (β=0.12) had the largest effect(P<0.05), with contribution rates of 2.5% and 1.2%, respectively. The relationship between gross motor skills and physical activity had nothing to do with gender and age. Conclusion Children’s gross motor skills in the 3-6 year-old population should be improved and may be an effective way to promote physical activity.

Objective: To conduct a meta-analysis of relevant literature and systematically evaluate the effects of physical activity on the executive function and academic performance of school-age children (6-12 years old) in the past 20 years, and to provide a new perspective for future interventions to promote physical activity of school-age children and school health decisions. Methods: Using systematic reviews and meta-analysis methods, papers regarding the eflect of phyical activity on executive function and academic performance among school-age children physical activities published during the period from January 1, 2000 to December 31, 2019 were retrieved in five databases including PubMed, Web of Science, Medline, Eric and SPORTDiscus. The English retrieval words were “child*” OR “pediatr*” OR “paediatr*” OR “teen*” OR “preadolescen*” OR “preadolescen*” OR “youth” OR (“primary” OR “elementary” AND “school*”) AND “control group” OR “control condition” OR “randomi*” OR “cross-over” AND “motor activity” OR “exercise” OR “physical fitness” OR “physical endurance” AND “executive function” OR “Inhibition (Psychology)” OR “problem solving” OR “cognition” AND “academic*” OR “school*” OR “education*” AND “achievement*” OR “performance*” OR “abilit*” OR “skill*” OR “competence”. Results: A total of 23 relevant literatures were included and evaluated. Longitudinal physical activity had a positive effect on executive function (Hedges’g=0.24, 95%CI=0.09-0.39) and academic performance (Hedges’g=0.26, 95%CI=0.02-0.49). Conclusion The study found that physical activity has a positive effect on the executive function and academic performance of school-age children. Interventions for promoting regular physical activity within a few weeks will achieve the greatest effect.

Objective:To investigate the changes in the nerve fiber layer of the cornea in patients with demyelinating optic neuritis (DON) and its correlation with visual acuity.Methods:A cross-sectional study. From March 2021 to July 2022, 27 cases (39 eyes) of DON patients diagnosed in the Department of Neurology and Ophthalmology of Beijing Tongren Hospital Affiliated to Capital Medical University were enrolled in this study. According to the serological test results, the patients were divided into aquaporin 4 antibody associated optic neuritis (AQP4-ON group) and myelin oligodendrocyte glycoprotein antibody associated optic neuritis (MOG-ON group), with 15 cases (19 eyes) and 12 cases (20 eyes) respectively. According to previous history of glucocorticoid treatment, the patients were divided into glucocorticoid treated group and non-glucocorticoid treated group, with 17 cases (27 eyes) and 10 cases (12 eyes) respectively. Twenty healthy volunteers (20 eyes) with age- and gender-matched were selected as the control group. All eyes underwent best corrected visual acuity (BCVA) and in vivo confocal microscopy (IVCM) examinations. BCVA was performed using Snellen's standard logarithmic visual acuity chart, which was converted into logarithmic minimum angle resolution (logMAR) visual acuity during statistics. The corneal nerve fiber length (CNFL), corneal nerve fiber density (CNFD), corneal nerve fiber branch length (CNBL), corneal nerve fiber branch density (CNBD) and the density of corneal dendritic cells (DC) were detected by IVCM examination. Parameter comparison between groups by t-test and Kruskal-Wallis rank sum test. The correlation between logMAR BCVA and pamameters of corneal nerve fibers were analyzed using Spearman analysis. Results:The CNFL, CNFD, and CNBL of the DON group and the control group were (10.67±2.55) mm/mm 2, (57.78±12.35) root/mm 2, (3.27±1.34) mm/mm 2, and (13.74±3.05) mm/mm 2, (70.95±13.14) root/mm 2, and (4.22±1.03) mm/mm 2, respectively; the difference in CNFL, CNFD, and CNBL between the two groups were statistically significant ( t=4.089, 3.795, 2.773; P<0.05). The CNFL, CNBL, and CNBD of the affected eyes in the MOG-ON group and AQP4-ON group were (12.02±2.13) mm/mm 2, (3.80±1.19) mm/mm 2, (47.97±8.86) fibers/mm 2, and (9.25±2.19) mm/mm 2, (2.72±1.19) mm/mm 2, (39.43±13.86) fibers/mm 2, respectively; the differences in CNFL, CNBL, and CNBD between the two groups were statistically significant ( t=-4.002, -2.706, -2.306; P<0.05). The corneal DC density of the patients in the hormone treated group and the non-hormone treated group was (24.43±8.32) and (41.22±9.86) cells/mm 2, respectively. The difference in corneal DC density between the two subgroups was statistically significant ( P<0.001). Correlation analysis showed that there was a significant negative correlation between logMAR BCVA and CNBL and CNFL in patients with DON ( r=-0.422, -0.456; P<0.05). Conclusions:There are different degrees of corneal nerve fiber damage in patients with different types of DON. There was a negative correlation between BCVA and the length of corneal nerve fibers.

Objective:To investigate the stability of fat emulsions after the preparation of parenteral nutrient solution under different storage conditions.Methods:Standardized parenteral nutrient solution was used to prepare a total of 24 bags of nutrient solution with the same formula, except for that Group A (12 bags) contains 20% of medium and long chain fat emulsion (C6-24) while Group B contains 20% of C8-24. The preparations were stored under 2-8℃, 23-25℃, and 35-37℃ and were examined at 24h, 48h and 72h after preparation. The appearance, average size of fat particles, pH value of nutrient solution, and lipid peroxidation were investigated.Results:After storage at 4℃, 25℃ and 36℃ for 24h, 48h and 72h respectively, both groups of preparations showed no obvious change in appearance. There was no significant difference in pH ( P>0.05) nor lipid peroxidation ( P>0.05). Conclusion:Both kinds of fat emulsion are stable in terms of pH value, fat particle size and lipid peroxidation, and can be used for patients receiving intravenous nutrition support.

Objective:To measure the anatomical parameters of the simulated low tibial tunnel of posterior cruciate ligament (PCL) based on knee CT images so as to provide clinical reference for accurate location of the tunnel.Methods:The CT images of 201 healthy knee joints collected at Department of Orthopedics, The Second Hospital of Lanzhou University from June 2016 to September 2021 were used for simulation of the PCL low tibial tunnel. The anatomical parameters of the tibial tunnel were measured using the RadiAnt DICOM Viewer. The primary measures included the angle between tibial plateau and tibial tunnel (ATPT) and the perpendicular distances from the tibial tunnel entrance and exit point to the tibial plateau (L1 and L2). The secondary measures included the angle between tibial plateau and posterior slope (PSA), the angle between tibial anatomical axis and central line of tibial tunnel (ATAA), the angle between posterior tibial slope line and the central line of tibial tunnel (APST), the anterior and posterior diameter of tibial plateau (APD), the length of posterior tibial slope (LPTS), and the length of tibial tunnel (LTT). The measurement results were analyzed according to the body height (divided into 3 groups: a 1.00 to 1.60 m group, a 1.61 to 1.70 m group, and a ≥1.71 m group) and gender using the software IBM SPSS 26.Results:The primary measures: ATPT was 37.0°±4.5°, and L1 and L2 were respectively (57.8±7.4) mm and (34.5±3.3) mm. The secondary measures: PSA 128.1°±5.4°, ATAA 52.7°±4.1°, APST 89.1°±5.9°, APD was (32.9±2.6) mm, LPTS (20.5±2.4) mm, and LTT (40.9±5.7) mm. After grouping by gender, there was no significant difference in PSA between men and women ( P>0.05) while there were significant differences in the other indexes between men and women ( P<0.05). After grouping by body height, there was no significant difference in ATPT, PSA, APST or ATAA between the 3 groups (1.00 to 1.60 m group, 1.61 to 1.70 m group and ≥1.71 m group) ( P>0.05) while there were significant differences in L1, L2, APD, LPTS and LTT between the 3 groups ( P<0.05). Conclusions:Based on the knee CT images, the primary measures of PCL low tibial tunnel are as follows: the angle between tibial plateau and tibial tunnel is 37.0°±4.5°, and the perpendicular distances from the tibial tunnel entrance and exit point to the tibial plateau are (57.8±7.4) mm and (34.5±3.3) mm, respectively. Gender and body height are the important factors influencing the above measurement outcomes.
