Abstract The framework of pediatric inactivity triad (PIT) consists of three core factors:exercise deficit disorder, pediatric dynapenia, and physical illiteracy. It emphasizes that physical activity (PA) insufficiency is not a singular phenomenon but rather a vicious cycle resulting from the interaction of multiple factors. Based on the PIT framework, the paper explores its core components and their interrelationships, as well as analyzes the framework s application value and practical implications for improving PA levels among Chinese children and adolescents,to provide a systematic theoretical perspective for analyzing the complex causes of PA insufficiency in children and adolescents, and to offer a scientific basis for developing intervention strategies.

BACKGROUND:Hydrogen,as an antioxidant,can reduce oxidative stress induced by strenuous exercise and achieve the effect of improving fatigue.Several studies have been reported on the potential effects of hydrogen-rich water or hydrogen-rich gas on improving exercise fatigue and athletic performance. OBJECTIVE:To investigate the effects of hydrogen-rich gas inhalation prior to high-intensity exercise on proprioception and muscular endurance performance after exercise fatigue. METHODS:Through a randomized,double-blind,crossover,and repeated measurement experimental design,24 healthy men were randomly divided into group A and group B,with 12 in each group.In the first phase of the crossover experiment,group A inhaled hydrogen-rich gas(hydrogen group)for 20 minutes and group B inhaled placebo gas(air;placebo group)for 20 minutes.Then,cycle ergometers were used to establish the fatigue model.Visual analog fatigue scale,heart rate variability,knee joint proprioception(passive position perception,joint motion perception,and muscle force perception)and isometric knee extension muscle endurance were tested before and after intervention.After a 7-day washout period,two groups exchanged intervention methods and the above tests were performed again in the second phase of the experiment.Differences between the results of groups A and B in the two phases were compared,and finally the results of the two phases were integrated to compare the overall differences between hydrogen intervention and placebo intervention. RESULTS AND CONCLUSION:In the first phase of the crossover experiment,the visual analog fatigue scale score of the hydrogen group after intervention was significantly lower than that of the placebo group(P<0.01).The root mean square of the difference between the adjacent R-R,mean low-frequency output power,mean high-frequency output power,and isometric muscle endurance after intervention in the hydrogen group were significantly higher than those in the placebo group(P<0.05).Passive position perception and joint motion perception after intervention in the hydrogen group were significantly better than those in the placebo group(P<0.05).There was no significant difference in muscle force perception between the two groups(P>0.05),but muscle force perception in the placebo group after intervention was significantly worse than that before intervention(P<0.01).The difference trend of all test results after intervention in the two groups in the first phase of the experiment showed the same results in the second phase of the experiment.The integrated results also showed that the hydrogen group had better test values for the above indicators than the placebo group(P<0.05).Linear regression analysis showed a positive correlation between post-intervention visual analog fatigue scale scores and passive position perception results(r=0.327,P=0.023),i.e.,the higher subjective fatigue level after high-intensity exercise indicated the worse passive position perception results.To conclude,inhaling hydrogen-rich gas before high-intensity exercise can reduce the degree of fatigue after exercise,thereby improving proprioception and muscle endurance performance,which may be a new strategy to reduce the occurrence of injury.And its effectiveness can be achieved repeatedly.

Objective To compare the acute effect of high-intensity interval training(HIIT)and moder-ate-intensity continuous training(MICT)on ectopic lipid levels in overweight and obese youth.Methods Twenty obese or overweight subjects,aged 24.15±1.98 years,participated in two crossover random-ized own-control trials of HIIT and MICT.In HIIT,participants performed high-intensity cycling at 85%VO2max for 9 sets of 2 minutes,interspersed with low-intensity cycling at 25%VO2max for 10 sets of 2 minutes each and the session started and ended with low-intensity cycling at 25%VO2max.Howev-er,in MICT,all participants cycled continuously at 50%VO2max for 60 minutes,maintaining a pedal-ing speed of 50-55 rpm,with a 7-day interval between the two interventions.Before,as well as im-mediately,60 and 120 minutes after exercise intervention,all subjects underwent magnetic resonance imaging(MRI)scans to observe the fat fraction(FF)and spin relaxation rate R2* of the rectus femo-ris,biceps femoris and liver.Results Rectus femoris FF decreased significantly immediately after HIIT and MICT(P<0.05),without significant differences.Moreover,sixty minutes after MICT,rectus femoris FF returned to pre-exercise levels,while 120 minutes after HIIT,the values restored to the pre-exer-cise levels.However,no significant changes were found in the biceps femoris and liver FF before and after the two exercise interventions(P>0.05).Meanwhile,the rectus femoris R2* was significantly lower in both the HIIT and MICT groups immediately after exercise(P<0.05)and remained significantly low-er in both groups 120 minutes after the exercise(P<0.05),with no significant differences between the two groups.Biceps femoris and liver R2* were significantly higher in both groups immediately after the exercise intervention(P<0.05).Liver R2* returned to pre-exercise levels 120 minutes after HIIT group,but remained significantly lower than pre-intervention levels after MICT(P<0.05).Conclusion Both acute HIIT and MICT are effective in reducing intramuscular fat in the working muscles of over-weight and obese adults but have no significant effect on liver fat.Acute HIIT and MICT show similar fat-burning effects,but a single bout of exercise proves more effective for fat loss in the active mus-cles compared to the antagonist muscles.

Objective:To observe the effects of warming needle therapy combined with the modified Hua Tan Tong Luo Tang(decoction for dissipating phlegm and unblocking collaterals)on post-stroke cognitive impairment due to obstruction of wind-phlegm. Methods:A total of 78 patients who met the inclusion criteria were randomly assigned to an observation group and a control group,with 39 patients in each group.Both groups received conventional treatment.The control group was additionally treated with the modified Hua Tan Tong Luo Tang,while the observation group received warming needle therapy in addition to the treatment given to the control group.Scores on the mini-mental state examination(MMSE),Montreal cognitive assessment(MoCA),and activities of daily living(ADL)were assessed before and after treatment.Adverse reactions and clinical efficacy were analyzed and compared between the two groups after treatment. Results:The total effective rate was 82.1%in the observation group and 61.5%in the control group,showing statistical significance between the two groups(P<0.05).After treatment,the MMSE,MoCA,and ADL scores of both groups were significantly higher than those before treatment within each group(P<0.05).Notably,the scores in the observation group were higher than those in the control group(P<0.05).No adverse reactions occurred in either group during the treatment period. Conclusion:Based on the conventional treatment,compared to modified Hua Tan Tong Luo Tang alone,warming needle therapy combined with the modified Hua Tan Tong Luo Tang showed superior clinical efficacy in treating post-stroke cognitive impairment due to obstruction of wind-phlegm,and this combined therapy also showed high safety.

Objective:To determine the therapeutic effect of in vitro cultivation of bezoar on a mouse model adding disease with syndrome of coronavirus pneumonia with Yidu Xifei syndrome. Method:BALB/c mice were randomly divided into six groups according to their weight grade： normal group， HCoV-229E infection group， cold and damp group， a mouse model combining disease with syndrome of coronavirus pneumonia with Yidu Xifei syndrome， and high and low dose group of in vitro cultivation of bezoar. The combination model of human coronavirus pneumonia with Yidu Xifei syndrome mice was established by the method of cold dampness condition stimulation+coronavirus HCoV-229E infection. In vitro cultivation of bezoar （0.128，0.064 g·kg^-1） was administrated by gavage for 3 days from the day of infection. The observation indexes included： general state observation of mice， inhibition rate of lung index and lung index of mice. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the viral load in the lung tissues of mice. Serum levels of motilin（MTL）， gastrin （GAS）， and cytokines interleukin（IL）-10，IL-6， tumor necrosis factor-α（TNF-α）and interferon-γ（IFN-γ） in lung tissue of mice were determined by enzyme-linked immunosorbent assay（ELISA）. The percentages of CD4⁺ T lymphocytes，CD8⁺ T lymphocytes and B lymphocytes in the blood of mice were determined by flow cytometry. Result:The high and low dose group of in vitro cultivation of bezoar can significantly improve the general condition of model mice. Compared with blank group， model group mice lung index increased significantly （P<0.01）， nucleic acids significantly increased expression of lung tissue in mice （P<0.01）， significantly higher serum MTL content in mice， GAS content significantly decreased （P<0.05，P<0.01）， lung tissue cells in the immune factor TNF-α， IL-10 and IL-6 were significantly increased （P<0.01）， peripheral blood lymphocyte CD4⁺ T cells in mice， The percentages of CD8⁺ T cells and B cells were significantly decreased （P<0.01）. Compared with model group， in vitro cultivation bezoar mice lung index of high and low dose group were significantly lower （P<0.01）， the lung tissue of mice express nucleic acid decreased significantly （P<0.01）， MTL content decreased significantly （P<0.01）， the lung tissue of mice in the IL-6， IL-10， the TNF-α， IFN-γ levels were significantly lower （P<0.01）， in vitro cultivation bezoar high dose group can significantly increase the CD4⁺ T cell percentage （P<0.05）， in vitro cultivation bezoar can to a certain extent reduce model mice lung inflammatory exudation， pulmonary interstitial edema， as well as blood stasis symptoms. Conclusion:In vitro cultivation of bezoar has a significant therapeutic effect on a mice model adding disease with syndrome of coronavirus pneumonia with Yidu Xifei syndrome. It can be treated by reducing the lung index of the model mice， improving the pathological damage of the lung tissue， adjusting the immune effective and inhibiting the clearing of inflammatory factors， and to provide a laboratory basis for clinical medication.

Objective To compare the clinical features of pulmonary infections with Mycobacterium intracellulare and Mycobacterium abscessus in the tuberculosis intensive care unit (ICU).Methods Clinical data of 74 patients with non-tuberculous mycobacterial pulmonary infection (NTM) admitted in tuberculosis ICU of Hangzhou Red Cross Hospital from January 2012 to May 2017 were retrospectively analyzed.There were 54 patients infected with Mycobacterial abscesses, 16 patients with Mycobacterial intracellular, 2 patients with Mycobacterium avium and 2 patients with Mycobacterium kansasii.The clinical features, imaging manifestations, treatment and prognosis of patients with Mycobacterial intracellular and Mycobacterial abscesses lung infections were compared.SPSS 21.0 software was used for statistical analysis.Survival curve analysis was performed using GraphPad Prism V 5.01.Results Among 74 patients with NTM lung disease , the infection rate of Mycobacterium abscessus was 72.87%(54/74), and the infection rate of Mycobacterium intracellular was 21.62%( 16/74 ).The age of patients with Mycobacterium intracellularis pulmonary disease was younger and the length of ICU stay was shorter than those of patients with Mycobacterium abscessus (t＝－2.729 and －6.150, P＜0.05 or ＜0.01).There was no significant difference in the gender distribution and APACHE Ⅱ scores between the two groups ( both P＞0.05).The proportion of patients with chronic obstructive pulmonary disease ( COPD) in Mycobacterium intracellularis group was significantly lower and the proportion of patients with bronchiectasis was significantly higher than those in Mycobacterial abscesses group (χ2＝3.902, P＜0.05; χ2＝23.888, P＜0.01).The proportion of patients complicated with stroke sequelae , Parkinson's disease and other central nervous system diseases ( χ2＝14.872, P＜0.01) and diabetes (χ2＝3.902, P＜0.05) in Mycobacterial abscess group was significantly higher, and that of hemoptysis was significantly lower (χ2＝9.717, P＜0.01) than those in Mycobacterium intracellularis group.Respiratory failure (93.75%) and septic shock (6.25%) were the main reasons of ICU admission for patients with Mycobacterium intracellularis lung disease; while respiratory failure (90.74%), heart failure (11.11%) and renal failure (1.85%) were main reasons of ICU admission for patients with Mycobacterial abscesses; there were no significant differences in the causes of ICU admission between the two groups ( all P＞0.05).The proportion of NTM isolated from patients with Mycobacterial intracellular lung disease, prior to mechanical ventilation was significantly higher than that of patients with Mycobacterial abscess ( χ2＝30.366, P ＜0.01 ).In imaging, the proportion of bronchiectasis in Mycobacterium intracellularis lung disease group was significantly higher than that in Mycobacterial abscesses lung disease group (χ2＝23.888, P＜0.01).There was no significant difference in the 28-day mortality rate between the two groups (χ2＝3.244, P＞0.05), while the survival rate in patients with Mycobacterium intracellularis lung disease within 120 days was significantly higher than that in patients with Mycobacterial abscesses lung disease (χ2＝12.780, P＜0.01).Conclusion When critically ill patients are positive for acid-fast staining, the ICU physician should consider the possibility of NTM lung disease.For severe patients with long-term mechanical ventilation , Mycobacterium abscessus infection should be considered first.

Objective To observe the clinical efficacy of electroacupuncture plus nasal irrigation in treating upper airway cough syndrome (UACS).Method A total of 114 UACS patients were randomized into 3 groups, 38 cases in each group. Group A was treated with acupuncture plus electrical stimulation with sparse-dense wave, group B was intervened by nasal irrigation with Shuang Huang Lian, and group C was treated with the two methods together. The clinical efficacies of the three groups were compared.Result The total effective rates were respectively 84.2%, 73.7% and 94.7% in group A, group B and group C. The total effective rate of group C was significantly different from that of group A and group B (P<0.05).Conclusion Electroacupuncture plus nasal irrigation can produce a more significant therapeutic efficacy compared to electroacupuncture or nasal irrigation alone.

We analyzed the whole genome coding sequence of Volvariella volvacea to study the pattern utilization of codons by Codon W 1.4.2. As results, 24 optimal codons were identified. Moreover, the frequency of codons usage was calculated by CUSP program. We compared the frequency of codons usage of V. volvacea with other organisms including 6 modal value species (Homo sapiens, Saccharomys cerevisiae, Arabidopsis thalian, Mus musculus, Danio rerio and Drosophila melanogaster) and 4 edible fungi (Coprinopsis cinerea, Agaricus bisporus, Lentinula edodes and Pleurotus ostreatus). We found that there were less differences in 3 edible fungi (excluding Pleurotus ostreatus) than 6 modal value species, comparing with the frequency of codons usage of V. volvacea. With software SPSS16.0, cluster analysis which showed differences in the size of codon bias, reflects the evolutionary relationships between species, which can be used as a reference of evolutionary relationships of species. This was the first time for analysis the codon preference among the whole coding sequences of edible fungi, serving as theoretical basis to apply genetic engineering of V. volvacea.
