Objective: To explore the short-term improvement effect of physical exercise and cognitive training on inhibitory control function of college students, and to clarify the temporal quantitative-effectiveness relationships between long-term exercise-integrated cognitive interventions and inhibitory control function of college students, in order to provide a reference for promoting inhibitory control function in this population. Methods: College students from Tianjin University of Sport were recruited in May 2022 to participate in the intervention study, which included both short-term and long-term interventions. The short-term intervention used a 2 (physical exercise: yes，no) × 2 (cognitive training: yes，no) between-groups design, with 69 participants randomized into a movement integration cognitive group ( n =18)，a physical exercise group ( n =16)，a cognitive training group ( n =17)，and a control group (sedentary viewing of a health information video, n =18)，for a 30 min intervention.The long term intervention used a mixed experimental design with a 2 (intervention groups; intervention group，control group, between-group variable) ×5 (intervention time: pre-test, 1 week, 4 weeks, 6 weeks, and 8 weeks, within-group variable) mixed experimental design with 24 participants, including 13 in the intervention group，who underwent the exercise-integrated cognitive intervention for 30 min, 3 times per week, and 11 in the control group, who maintained their daily activities without the intervention. The main effects of the independent variables and their interactions were analyzed using covariance and repeated measures ANOVA. Results: There was a statistically significant interaction between physical exercise and cognitive training on accuracy of the Flanker task for the short intervention[ F (1,64) =7.05, P =0.01, η 2 P=0.10], and the simple effect test showed that cognitive training reduced accuracy of responses in the presence of physical exercise condition( P =0.02), and the main effect of physical exercise among college students was significant for the reaction time [ F (1,65) =14.12, P < 0.01 , η 2 p =0.18]; for Flanker task reaction time in the long-term intervention, the main effect of intervention time was significant[ F (4,19) = 3.03 , P =0.04, η 2 P =0.39].However, the intervention results of 1, 4, 6 and 8 weeks in the intervention group [(28.13±10.32)( 14.14 ±26.98)(13.54±25.61)(15.14±21.34)ms] were all better than the pre-test [(77.54± 39.34 )ms], the main effect of intervention group was significant [ F (1,22) =6.96, P =0.02, η =0.24]. Conclusion In a short-term intervention for inhibitory control function in college students, physical exercise is more effective than cognitive training; long-term exercise and cognitive training can improve the inhibitory control function of college students.

Abstract In recent years, the overall incidence of scoliosis in children and adolescents in China is on the rise, and it has become the third largest "killer" affecting the health of children and adolescents in China after obesity and myopia. The dysfunction caused by spinal deformity has no obvious pathological manifestations or clinical symptoms in children and adolescents (except for severe scoliosis). It is easy to be ignored in the early stage, but if it is not intervened in time, this will cause serious damage to the long term prognosis and quality of life of the patients. Therefore, through early scoliosis screening, we can effectively monitor the spinal health status of children and adolescents in China, ensure timely diagnosis of the disease, timely intervention (brace and other conservative treatment), and play the role of early prevention. Avoid further deterioration of scoliosis and surgical intervention. This article will focus on the research progress of screening and conservative treatment of scoliosis.

Objective To compare the effects of Autoregressive Integrated Moving Average model-X (ARIMAX) and multivariate Long Short Term Memory Network (multivariate LSTM) in the prediction of daily total death toll in Yancheng City. Methods Based on total death toll data, meteorological data and air quality data from January 1^st, 2014 to June 30^th,2017 in Yancheng City, Jiangsu province, ARIMAX model and multivariate LSTM model were established to predict the daily total death toll from July 1^st,2017 to July 14^th,2017. RMSE, MAE and MAPE were used as evaluation indexes to compare the prediction effects of these two models. Results RMSE, MAE and MAPE of ARIMAX model and multivariate LSTM model were 20.742、15.094、9.921 and 47.182、35.863、19.633, respectively. Conclusion ARIMAX model is better than multivariate LSTM model to predict the daily death toll in Yancheng city.

The soaking and fermentation of Baphicacanthus cusia( Nees),the important intermediate link of Indigo Naturalis processing,facilitates the synthesis of indigo and indirubin precursors and the dissolution of endogenous enzymes and other effective components,while the role of microorganisms in the fermentation is ignored. The present study investigated the changes of microbial community structure in Indigo Naturalis processing based on 16 S amplicon sequencing and bioinformatics. Meanwhile,the contents of indigo,indirubin,isatin,tryptanthrin,indole glycoside,etc. were determined to explore the correlation between the microorganisms and the alterations of the main components. As demonstrated by the results,the microbial diversity decreased gradually with the fermentation,which bottomed out after the addition of lime. Proteobacteria,Bacteroidetes,and Firmicutes were the main dominant communities in the fermentation. The relative abundance of Proteobacteria declined gradually with the prolongation of fermentation time,and to the lowest level after the addition of lime. The relative abundance of Firmicutes increased,and that of Bacteroidetes decreased first and then increased. The contents of effective substances in Indigo Naturalis also showed different variation tendencies. As fermentation went on,indole glycoside decreased gradually; indigo first increased and then decreased; indirubin and isatin first decreased and then increased; tryptanthrin gradually increased. Those changes were presumedly related to the roles of microorganisms in the synthesis of different components. This study preliminarily clarified the important role of microorganisms in the soaking and fermentation and provided a scientific basis for the control of Indigo Naturalis processing and the preparation of high-quality Indigo Naturalis.

OBJECTIVE： To study the mechanism of analgesic effect of 8-O-acetyl-safalinoside （8-OaS） on chronic inflammatory pain model rats. METHODS ：Totally 30 male SD rats were divided into sham operation group （normal saline ）， model group （normal saline ），8-OaS low-dose ，medium-dose and high-dose groups （3，10，30 μg/kg），with 6 rats in each group. Except for sham operation group ，other groups were given planter injection of Freund ’s complete adjuvant to induce chronic inflammatory pain model. After successful modeling ，the rats in each group were given corresponding drugs intrathecally ，once a day，for 7 consecutive days. Then Von-Frey filaments were used to detect the planter pain threshold of the rats in each group ；the area under the planter pain threshold curve of each group and the half effective dose （ED50）of 8-OaS were calculated. Another 36 male SD rats were divided into sham operation group （normal saline ），model group （normal saline ）and 8-OaS group （dose of ED50），and the modeling method and administration route were the same as above. Immunofluorescence histochemical staining was used to observe the positive expression of ionized calcium binding adapter molecule 1（Iba-1）and signal molecule phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）；Western blotting assay was used to determine the expression of Iba- 1，p-p38 MAPK，IL-1β，IL-6 and TNF-α in spinal dorsal horn of rats. RESULTS：Compared with sham operation group ，plantar pain threshold and area under the curve in model group were reduced significantly （P＜0.01）. Compared with model group ，plantar pain threshold increased significantly after 5，6，7 days of administration in 8-OaS low-dose group （P＜0.05），plantar pain threshold and area under the curve in 8-OaS medium-dose and high-dose groups were increased significantly （P＜0.05 or P＜0.01）. Most of above indexes in each dose group of 8-OaS were signifficantly different ，and ED 50 of 8-OaS was 18.87 μ g/kg. Results of immunohistochemistry staining and Western blotting showed that p-p 38 MAPK was mainly expressed in Iba- 1 positive cells. Compared with sham operation group ，the fluorescence density of Iba- 1 and p-p 38 MAPK in spinal dorsal horn ，the expression of Iba-1，p-p38 MAPK，IL-6，IL-1β and TNF-α were significantly increased in model group（P＜0.05 or P＜0.01）. Compared with model group ，the fluorescence density of Iba- 1 and p-p 38 MAPK in spinal dorsal horn ，the expression of Iba- 1，p-p38 MAPK， IL-6，IL-1β and TNF-α were decreased significantly in 8-OaS group （P＜0.05）. CONCLUSIONS ：Intrathecal administration of 8-OaS can effectively alleviate chronic inflammatory pain in rats. The mechanism may be related to the inhibition of the phosphorylation of p 38 MAPK and the expression of IL- 6，IL-1β and TNF-α.

OBJECTIVE： To study the effects of 8-O-acetyl-shanzhiside methylester （8-OaS） on the expression of histone deacetylase 1-5 （HDAC1-5） in the spinal dorsal horn of chronic inflammatory pain model rats， and its relationship with Janus-activated kinase 2-signal transductions and activators of transcription 3 （JAK2-STAT3） signaling pathway. METHODS： SD rats were randomly divided into normal control group， sham operation group （normal saline）， complete Freund’s adjuvant （CFA） group （normal saline）， 8-OaS low-dose， medium-dose and high-dose groups （2， 20， 200 μg/kg）， with 6 rats in each group. Except for normal control group and sham operation group， chronic inflammatory pain model was induced by subcutaneous injection of CFA into the left hind toe of rats in other groups； after modeling， those groups were given relevant medicine intraperitoneally， once a day， for consecutive 7 d. Thermal radiation method was used to detect the latency of paw withdraw in rats on the 1st， 2nd， 3rd， 4th， 5th， 6th， 7th， 8th， 11th and 15th day of administration. Rats were grouped and given medicine according to the above method of the latter 5 groups. The protein expression of HDAC 1-5， phosphorylated JAK2 （pJAK2） and phosphorylated STAT3 （pSTAT3） in the spinal dorsal horn of lumbar enlargement segment in rats were detected by Western blot method after last medication. Rats were randomly divided into sham operation group （normal saline）， CFA group （normal saline）， 8-OaS group （20 μg/kg） and JAK2-STAT3 inhibtor AG490 group （8 mg/kg）， with 6 rats in each group； IP model was established by same method as above and then were given relevant medicine intraperitoneally， once a day， for consecutive 7 d. The expression of HDAC5 and glial fibrillary acidic protein （GFAP） in spinal dorsal horn of rats were detected by immunofluorescence histochemical staining. RESULTS： Compared with normal control group and sham operation group， the latency of paw withdraw was shortened significantly in other groups （P＜0.05）. Compared with CFA group， the latency of paw withdraw was prolonged significantly in 8-OaS low-dose， medium-dose and high-dose groups （P＜0.05）， in dose-dependent manner. Compared with sham operation group， the protein expression of HDAC 1-5， pJAK2 and pSTAT3 in spinal dorsal horn of rats were increased significantly in CFA group （P＜0.05）. Compared with CFA group， the protein expression of HDAC5， pJAK2 and pSTAT3 in spinal dorsal horn of rats were decreased significantly in 8-OaS low-dose， medium-dose and high-dose groups （P＜0.05）， but there was no statistical significance in the protein expression of HDAC 1-4 （P＞0.05）. HDAC5 was expressed on astrocytes in the spinal dorsal horn； compared with sham operation group， the expression of GFAP and HDAC 5 were increased significantly in spinal dorsal horn of rats in CFA group （P＜0.05）. Compared with CFA group， the expression of GFAP and HDAC5 in spinal dorsal horn of rats were decreased significantly in 8-OaS group and AG490 group （P＜0.05）. CONCLUSIONS： 8-OaS can effectively relieve CFA-induced chronic inflammatory pain， the mechanism of which may be associated with the down-regulation of HDAC5 expression and the phosphorylation levels of JAK2 and STAT3.
