Objective To establish the energy expenditure(EE)prediction models of health Qigong Wuqinxi based on heart rate combined with accelerometer counts in different body parts,so to provide a reference for monitoring EE of Wuqinxi.Methods Seventy-four healthy college students aged 18-30 were selected as the research objects.They were divided into a skilled group of 39(21 males and 18 females)and a primary group of 35(17 males and 18 females)according to their level of practice,with 55 in the model group and 19 in the validation group.When performing a set of Wuqinxi,all subjects were recorded heart rate(HR),accelerometer counts[the average counts of X-axis,Y-axis,Z-axis and vector magnitude(VM)],and EE-related indicators by wearing the Polar heart rate moni-tor,ActiGraph-GT3X+accelerometers(9 parts:waist,both arms,both wrists,both thighs,and both ankles)and CORTEX Meta Max3B-R2 portable indirect calorimeter.Based on the accurate EE mea-sured by the gas metabolism meter,linear regression models of only HR,only accelerometer counts,or HR combined accelerometer counts were established,and their accuracy was analyzed and com-pared.Results The EE of Wuqinxi was significantly correlated with gender,height,weight,muscle mass,HR-related indicators,and accelerometer counts in different parts(X-axis counts of the waist,VM values of the left thigh and counts of the X-axis and Y-axis,VM values of the right thigh and the Y-axis,Z-axis count value,left ankle VM value and Y-axis count value,right ankle VM value and Y-axis,Z-axis count value)(P<0.05).Moreover,the adjusted R2 of the prediction model of only HR,only accelerometer counts,and the both were 0.582,0.508 and 0.678,respectively(P<0.05).The correlation between the predicted and measured values ranged between 0.706 and 0.817.Accord-ing to the Bland-Altman analysis,for each model,all except one error value fell outside the 95%confidence interval.That is,all models had an excellent fitting effect and high accuracy.Among them,the combined model was of the best prediction effect:EE(kcal)=-20.089+0.279×body weight(kg)+0.243×ΔHR(exercise HR-quiet HR,bpm)+0.001×Right thigh Y-axis count value+0.181×exer-cise HR(bpm)-4.202×gender(male=0,female=1).Conclusion The EE prediction model of Wuqinxi es-tablished on HR combined with accelerometer counts has the best effect and can calculate the EE more accurately.

Objective·To evaluate the relationship between anxiety level,alexithymia degree and quality of life in patients with anxiety disorders.Methods·Anxiety disorder patients admitted to the outpatient department of Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine from October 1,2020 to March 31,2023 were selected as the research subjects,and 438 patients were ultimately included after exclusion.Among them,there were 271 patients with generalized anxiety disorder,101 patients with panic disorder,48 patients with social anxiety disorder,12 patients with agoraphobia,and 6 patients with specific phobia.Hamilton Anxiety Scale(HAMA),Hamilton Depression Scale-17(HAMD-17),the twenty-item Toronto Alexithymia Scale(TAS-20)and World Health Organization Quality of Life Scale-Brief Form Questionnaire(WHOQOL-BREF)were used to assess the patients'anxiety level,depression level,alexithymia degree and quality of life,respectively,and the scale scores of patients with different subtypes of anxiety disorders were evaluated.Spearman correlation coefficient was used to analyze the correlation between anxiety level,depression level,alexithymia degree and quality of life in patients with anxiety disorders.Stepwise regression model was used to analyze the key variables affecting the quality of life in patients with anxiety disorders.Results·There were no significant differences in HAMA score,HAMD-17 score and TAS-20 score among patients with different subtypes of anxiety disorders,but the differences in WHOQOL-BRIEF score were statistically significant(H=10.076,P=0.039).The results of Spearman correlation analysis showed that the WHOQOL-BRIEF score of anxiety disorder patients was negatively correlated with HAMA score,HAMD-17 score and TAS-20 score(r=-0.256,P=0.000;r=-0.311,P=0.000;r=-0.342,P=0.000).The results of stepwise regression analysis showed that age,HAMA score,HAMD-17 score and TAS-20 score had significant impact on the quality of life of patients(all P<0.05).Conclusion·The quality of life in patients with different subtypes of anxiety disorders is different.The anxiety level,depression level and alexithymia degree are the key variables affecting their quality of life.

Ferroptosis is a form of regulated cell death that depends on iron and reactive oxygen spe-cies.Different from apoptosis,necrosis,and autophagy,ferroptosis is characterized by the accumulation of lipid peroxides in cells.Studies have discovered that ferroptosis is closely associated with the occurrence and develop-ment of tumors and inducing ferroptosis in tumor cells can enhance the therapeutic effects of drugs on tumors.This article summarizes the latest research progress in ferroptosis regarding its mechanisms and associations with tumors,aiming to provide a reference for further understanding the interaction mechanisms between ferroptosis and tumors and offering new insights and targets for the treatment of tumors.

Age-related hearing loss(ARHL)is a common chronic disease that poses a serious threat to the physical and mental health of the elderly in an aging society.It is a sensorineural hearing loss characterized by the loss of auditory hair cells,stria vascularis lesions,apoptosis of spiral ganglia,and degeneration of the audi-tory central nervous system,reducing the quality of life of the patients.This article reviews the research progress in the relationship of ARHL with Alzheimer's disease,depression,and frailty,as well as the daily intervention in ARHL.This review aims to improve people's awareness and attention to the health hazards of ARHL and to delay the occurrence and development of ARHL by implementing daily intervention measures to form a healthy lifestyle.

Objective To explore whether remote ischemic preconditioning(RIPC)can prolong the time of ultra-intense exercise(110%VO2max)by increasing the maximum cumulative oxygen deficit(MA-OD),and the specific ways of energy supply of the anaerobic metabolic system.Methods Twenty-four racquet athletes(22.2±2.0 years;174±9 cm;67.1±12.4 kg)completed three supramaximal intensi-ty tests on a treadmill at 110%VO2max intensity to exhaustion separated with Control,Placebo and RIPC interventions.RIPC was induced on the limbs on both sides(5×5 min alternating bilateral occlu-sion 220 and 60 mmHg for Placebo and RIPC interventions,respectively).Moreover,all groups under-went a fourth test with incremental load,and a fifth test with constant load at 40%,50%,60%,70%and 80%VO2max.Results The time to exhaustion and the MAOD of the RIPC group were both greater than those in the Placebo and Control groups(P<0.05).However,no significant differences were found in the average alternative maximal accumulated oxygen deficit(MAODALT),lactic anaerobic metabolism,alactic anaerobic metabolism and parameters of excess post-exercise oxygen consump-tion dynamic curve of the three groups(P>0.05).Meanwhile,in the RIPC group,the average MAOD was significantly higher than MAODALT(P<0.05).Pearson correlation analysis showed a significant rela-tionship between the improvement of MAOD and an increase in exhaustion time after RIPC interven-tion.Conclusion RIPC can improve supramaximal exercise performance of racquet athletes by enhanc-ing their MAOD,and the enhancement of glycolysis energy supply and lactic acid elimination is a po-tential intermediary of the improvement of sports performance.

Objective:To explore the family resilience resources in parents of children with congenital pseudarthrosis of the tibia (CPT) , so as to provide a reference for formulating nursing intervention to improve their family resilience.Methods:From December 2020 to January 2021, purposive sampling was used to select 13 father or mother of children with CPT in the Department of Orthopedics of Hunan Children's Hospital as the research object. Semi-structured interviews were conducted with parents of children with CPT using the phenomenological method in qualitative research. Colaizzi 7-step method was used to organize, summarize, analyze and refine the data.Results:The family resilience resources of parents of children with CPT were reflected in three aspects, namely, personal resources, family resources and social resources.Conclusions:Family resilience interventions should make full use of their own resources when implemented in parents of children with CPT. Individualized continuous intervention should be provided by taking into account the learning ability and psychological state of the children's parents and in combination with specific needs. The intervention target should include as many family members as possible, and strengthen the establishment of a diversified support system to help parents of children with a large number of social resources.

Objective:To investigate the value of peripheral blood eosinophils (EOS) in predicting the therapeutic effect of sublingual specific immunotherapy (SLIT) in patients with allergic rhinitis (AR).Methods:From January 2018 to June 2020, 200 patients with AR who received SLIT in Dongguan Kanghua Hospital were evaluated for their symptoms before treatment and 6 months after treatment. The curative effect was evaluated according to the improvement of the total symptom score. The number of eosinophils, percentage of eosinophils in peripheral blood were measured before treatment. The correlation between curative effect and EOS count and EOS percentage was analyzed and the value of these two indicators in predicting the efficacy of SLIT was evaluated.Results:Of the 200 AR patients, 178 patients were confirmed to have completed the treatment course of 6months. 126 effective and 52 ineffective, the effective rates were 70.8%. There was a weak correlation between the number of EOS in peripheral blood and the percentage of EOS in peripheral blood before treatment and the efficacy of SLIT ( r=0.168, P=0.048; r=0.250, P=0.001). The area under the curve of peripheral blood EOS count was 0.380, and the percentage of peripheral blood EOS was 0.355, which were all less than 0.5. Conclusions:There was no significant correlation between the number of peripheral blood EOS count and peripheral blood EOS percentage and the efficacy of SLIT , therefore, both of blood EOS count and blood EOS percentage have no value in predicting the efficacy of SLIT.

Objective To examine the prevalence of chikungunya virus in brain tissue samples from rat?like animals in Xiamen, Shenzhen and Guangzhou, and to explore whether the rat?like animals are potential sources of human chikungunya fever infections and the host of the virus. Methods Rat?like animals were trapped in residential areas, city parks, hospitals, markets and schools in Xiamen, Shenzhen and Guangzhou (Yuexiu and Baiyun districts) between January 2013 and June 2016. Brain tissue samples of the trapped animals were collected under sterile. Chikungunya virus was detected by using reverse transcription polymerase chain reaction (RT?PCR). Results Totally 1092 rat?like animals were trapped, which belonged to 7 species, 3 genera, 2 families, 2 orders. Rattus norvegicus was the dominant species in the indoor environment, Rattus losea was dominant in wild environment, and 1092 brain tissue samples were collected. No detectable chikungunya virus was found in the brain tissue samples by RT?PCR. Conclusion There is a low possibility that rat?like animals act infectious sources of human chikungunya fever infections and the host of the virus.
