OBJECTIVE To build a Tibetan-language medication service platform based on “internet+” and evaluate its effect on improving medication compliance and safety of Tibetan patients with chronic disease. METHODS Medication guidance contents of commonly used drugs in the outpatient department were summarized, translated and recorded in Tibetan-language or video to form a “text-audio-video” multi-dimensional “internet+ ” Tibetan-language medication service platform. A total of 387 Tibetan outpatients with chronic disease in our hospital after the implementation of “internet+” Tibetan-language medication service platform (from January 2024 to June 2024) in our hospital were selected as the intervention group, and 387 Tibetan outpatients before the implementation (from January 2023 to June 2023) were selected as the control group. Patients in the control group received conventional window-based Chinese-language medication services, while patients in the intervention group received both conventional window-based Chinese-language medication service and “internet+ ” Tibetan-language medication service. The medication compliance of patients was evaluated using the 12-item Medication Compliance Scale. A six-level causality assessment was conducted as the principles for analyzing adverse drug reactions (ADR) set by the National Center for ADR Monitoring. Additionally, statistics were compiled on the occurrence of ADR that were assessed as “definite”“probable” or “possible” in the causality assessment. RESULTS The proportion (31.0%) of patients with good medication compliance and compliance scores [39.0 (37.0,42.0)] of patients in the intervention group were significantly better than control group [7.0%, 21.0(19.0, 23.0)]( P<0.05). There were no statistically significant differences in the incidence of various types of ADR or the overall incidence between the two groups (P>0.05). CONCLUSIONS The “internet+” Tibetan-language medication service platform is constructed successfully; the service can effectively improve the medication compliance of Tibetan-language patients, but its effect on improving the medication safety of patients is limited.

OBJECTIVES:
To investigate the regulatory effects of Aurora-A in regulating proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) of cervical cancer cells and the role of actin-related protein 2/3 complex subunit 4 (ARPC4) in mediating its effects.
METHODS:
The plasmids pCDH-NC, pCDH-Aurora-A, and shRNA-ARPC4 were used for inducing Aurora-A overexpression or ARPC4 knockdown in HeLa cells. The cells were divided into vector group, Aurora-A overexpression group, Aurora-A overexpression+ARPC4 knockdown group, and Aurora-A overexpression+NF‑κBp65 inhibitor group and transfected with the corresponding plasmids. The proliferation, colony-forming ability, migration and invasion of the treated Hela cells was evaluated using EdU immunofluorescence assay, crystal violet staining, scratch assay, Transwell assay, and Matrigel assay. Western blotting was performed to detect the changes in cellular expressions of EMT-related proteins and expression levels of NF-κBp65 and ARPC4.
RESULTS:
The expression of ARPC4 was significantly decreased in HeLa cells with Aurora-A knockdown and increased in Aurora-A-overexpressing cells. Aurora-A overexpression obviously promoted proliferation, migration, and invasion abilities of HeLa cells, and these effects was significantly antagonized by ARPC4 knockdown. In Aurora-A-overexpressing cells, the phosphorylation level of NF-κBp65 and the expression level of ARPC4 were increased significantly, and application of the NF‑κBp65 inhibitor obviously lowered the expression level of ARPC4.
CONCLUSIONS
Aurora-A overexpression upregulates the expression of ARPC4 by activating the NF-κBp65 signaling pathway, thereby promoting migration, invasion and EMT of HeLa cells.

Objective:
To study the association between 24 h activities and Fundamental Motor Skills (FMS) among children with autism spectrum disorder (ASD) using compositional data analysis, and the expected changes in FMS after isochronous substitution of each activity, in order to provide reference basis for improving FMS levels in children with ASD.
Methods:
From October 2023 to April 2024, a total of 301 children with ASD aged 6-10 from 7 special education schools in Jinan, were investigated by cluster random sampling, and 24 h movement behaviors were calculated based on accelerator data. Test of Gross Motor Development- 2 was used to assess FMS. R software was used to perform the descriptive statistical, multiple linear regression and isochronous substitution analyses.
Results:
The proportion of moderatevigorous physical activity (MVPA) in children with ASD was positively related with FMS scores, locomotor, and object control skills ( β=12.42, 6.32, 6.10, P <0.01). Reallocating 15 min from sleep (SLP) to MVPA resulted in respective increases of 3.66, 1.91, and 1.75 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from sedentary behavior (SB) to MVPA resulted in respective increases of 3.72, 1.88 , and 1.83 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from light physical activity (LPA) to MVPA resulted in respective increases of 3.32, 1.57, and 1.74 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Moreover, reallocating 15 min from SB to LPA resulted in an increase of 0.28 points in locomotor skills ( P <0.05). Dose response analysis revealed that substitution of MVPA for SLP, SB, and LPA in children with ASD enhanced their FMS levels, and their substitution was asymmetrical; and substitution of LPA for SB enhanced locomotor skills level.
Conclusions
Among the 24 h movement behaviors, increasing the time spent on MVPA and LPA have positive impacts on the FMS of children with ASD. Schools and families should optimize the allocation of 24 h activity time in children with ASD, so as to promote the improvement of FMS levels of children with ASD.

ObjectiveTo construct a mouse model of inflammation-associated colorectal cancer (CAC) by using azoxymethane (AOM)/dextran sulfate sodium (DSS) and investigate the effect of Huangqintang on the gut microbiota structure of mice during the occurrence and development of CAC by 16S rRNA gene high-throughput sequencing. MethodA total of 225 C57BL/6J mice were randomized into 5 groups (n=45): Normal, model, positive drug (mesalazine), and high (18 g·kg-1) and low (9 g·kg-1)-dose Huangqintang. Except those in the normal group, each mouse was injected with 10 mg·kg-1 AOM on day 1 and day 5 within 1 week and then given 1.5% DSS solution for 7 days, which was then changed to sterile water for 14 days. This process referred to as one cycle, and mice were treated for a total of 3 cycles. On the first day of DSS treatment, mice were administrated with corresponding drugs by gavage, and the normal group and the model group were administrated with pure water by gavage, once a day until the end of the third cycle. The progression of CAC was divided into inflammation, proliferation, and tumorigenesis stages. At the end of each cycle, the body weight and colon length were measured for mice in each group, and the number of colon tumors in mice was recorded. Meanwhile, the disease activity index (DAI) was determined. The serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and carbohydrate antigen-199 (CA199), a tumor marker in the gastrointestinal tract of mice, were measured by ELISA. Hematoxylin-eosin staining was employed to observe colon lesions. At the same time, 3-5 pellets of fresh feces of mice in the normal group, model group, and high-dose Huangqintang group were collected, from which the fecal DNA of mice was extracted for 16S rRNA gene high-throughput sequencing. ResultCompared with the normal group, the model group showed decreased body weight (P<0.01), increased DAI, and shortened colon length (P<0.05) at the three stages. Compared with the normal group, the model group showed elevated levels of IL-1β, IL-6, and TNF-α (P<0.05) at the proliferation stage and elevated levels of CA199 at the inflammation, proliferation, and tumorigenesis (P<0.01) stages. Compared with the normal group, the model group presented obvious infiltration of inflammatory cells at the inflammation stage, thickening of the muscle layer and abnormal proliferation of mucosal layer cells at the proliferation and tumorigenesis stages, and final formation of advanced intraepithelial tumor lesions. Compared with the model group, the Huangqintang groups showed no significant improvement in the body weight, decreased DAI score, and increased colon length at the three stages, and the increase of colon length in the tumorigenesis stage was significant (P<0.01). At the tumorigenesis stage, the administration of Huangqintang inhibited tumor formation and growth, reduced the number of tumors (P<0.01), lowered the levels of IL-6 (P<0.05, P<0.01), TNF-α (P<0.05, P<0.01), and IL-1β at the three stages, and decreased CA199 at the inflammation stage as well as at the proliferation and tumorigenesis stages (P<0.01, P<0.05). Compared with the model group, the administration of Huangqintang reduced inflammation and abnormal cell proliferation, delaying the occurrence of tumors. Compared with the normal group, the model group showcased decreased alpha and beta diversity and altered structure of gut microbiota at the inflammation, proliferation, and tumorigenesis stages. The administration of Huangqintang adjusted the abundance and diversity of gut microbiota to the normal levels. At the inflammation stage, Huangqintang positively regulated two differential phyla (Firmicutes and Bacteroidetes) and three differential genera (Muribaculaceae, Rikenellaceae_RC9_gut_group, and Flavonifractor) in mice. At the proliferation stage, Huangqintang positively regulated two differential phyla (Bacteroidetes and Patescibacteria) and five differential genera (Muribaculaceae, Rikenellaceae_RC9_gut_group, Candidatus_Saccharimonas, norank_f__UCG-010, and Allobaculum). At the tumorigenesis stage, Huangqintang positively regulated two differential phyla (Proteobacteria and Patescibacteria) and eight differential genera (Muribaculaceae, Candidatus_Saccharimonas, norank_f_UCG-010, Lachnospiraceae_UCG-006, Allobaculum, Bacteroides, Lachnospiraceae_NK4A136_group, and Flavonifractor) in mice. ConclusionHuangqintang can intervene in the AOM/DSS-induced transformation of inflammation to CAC in mice by correcting inflammation and short-chain fatty acid-related microbiota disorders.

ObjectiveTo induce the rat model of ulcerative colitis (UC) with spleen-kidney Yang deficiency and liver depression, and explore the efficacy and mechanism of Sishenwan combined with Tongxie Yaofang (SSW&TXYF) based on the therapeutic principles of tonifying spleen, soothing liver, warming kidney, and astringing intestine. MethodSixty male SD rats were randomized into normal, model, mesalazine, and high-, medium-, and low-dose SSW&TXYF groups. The rats in other groups except the normal group were administrated with Sennae Folium decoction and hydrocortisone and received tail clamping for 14 days. On day 14, rats received enema with TNBS-ethanol solution to induce UC. The rats were administrated with corresponding drugs from day 15 of modeling, and the body weight and mental state were observed and recorded. The sucrose preference test was performed from day 25. On day 28, the rectal temperature was measured, and the rats were administrated with 3% D-xylose solution at a dose of 10 mL·kg-1 by gavage. Blood was sampled 1 h later, from which the serum was collected for measurement of the D-xylose content. The serum, hippocampus, and colorectum samples of rats were collected on day 29. The levels of gastrin (GAS), adrenocorticotropic hormone (ACTH), corticosterone (CORT), cyclic adenosine monophosphate (cAMP), cyclic guanosine monophosphate (cGMP), interleukin (IL)-4, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ in the serum and 5-hydroxytryptamine (5-HT) in the hippocampus were determined by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was employed to reveal the colonic lesions. The mRNA and protein levels of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinase (ERK), and c-Jun N-terminal kinase (JNK) in the colon tissue were determined by Real-time PCR and Western blot, respectively. ResultCompared with the normal group, the model group showed decreased body weight, anal temperature, and D-xylose content in the serum and increased GAS content (P<0.01). The modeling led to cAMP/cGMP unbalance and decreased the ACTH and CORT content in the serum (P<0.01), the preference for sucrose water, and the 5-HT content in the hippocampus (P<0.01). Moreover, it shortened the colorectal length and caused massive infiltration of inflammatory cells and severe structural damage in the colon tissue. High, medium, and low doses of SSW&TXYF improved above indicators (P<0.05, P<0.01), reduced inflammatory infiltration, and repaired the pathological damage of the tissue. Compared with the normal group, the model group showed lowered IL-4 level (P<0.01) and elevated TNF-α and IFN-γ levels (P<0.05, P<0.01) in the serum, as well as up-regulated expression of p38 MAPK, ERK, and JNK (P<0.05, P<0.01). Compared with the model group, SSW&TXYF elevated the IL-4 level (P<0.01), lowered the TNF-α and IFN-γ levels (P<0.05, P<0.01), and down-regulated the mRNA and protein levels of p38 MAPK, ERK, and JNK (P<0.05, P<0.01). ConclusionA rat model of UC with spleen-kidney Yang deficiency and liver depression was successfully established. SSW&TXYF can significantly mitigate this syndrome by reducing the inflammatory response in the colon and inhibiting the MAPK pathway.

BACKGROUND:The abnormal gait of stroke patients seriously affects their propulsive force during walking,which subsequently reduces their walking speed,walking distance,and stability,increases their risk of falls,and seriously affects their quality of life. OBJECTIVE:To review the relevant research on propulsive force deficits in stroke patients with hemiplegia,to summarize the understanding of existing researchers on propulsive force deficits,to analyze the relationship between propulsive force and gait,and finally to explain and compare the latest rehabilitation technologies used to improve propulsive force deficits,providing reference for clinical treatment. METHODS:Relevant literature was retrieved from WanFang,CNKI,PubMed,and Web of Science Core Collection through computer search.The Chinese and English search terms were"propulsive force OR propulsive,stroke OR cerebral infarction OR hemiplegia,walk* OR gait."The search time limit was from 2003 to 2023,and 71 articles were finally included for review and analysis. RESULTS AND CONCLUSION:Training targeting the hip and ankle joints may be more effective for patients'walking function,especially training with the application of flexible exoskeleton robots,but more sufficient evidence is still needed to use propulsion as a prognostic indicator of walking function in stroke patients.Biomechanical variables related to propulsive force include:the hip joint extension angle at terminal stance,ankle joint dorsiflexion torque,and knee joint extension.Damage to the corticospinal tract,cerebellar-cortical pathways,and the reticulospinal tract in hemiplegic patients are associated with reduced propulsive force and gait asymmetry.Propulsive force is crucial for the stability of healthy gait,and a decrease in propulsive force is unfavorable for gait stability.Gait symmetry is correlated with propulsive force,stride length symmetry,trunk displacement,and lower limb swing ability,with propulsive force being a key factor.Propulsive force can serve as a quantitative indicator for assessing the gait of hemiplegic patients,and evaluation of gait using propulsive force is beneficial for the long-term development of walking ability.Main rehabilitation techniques for improving propulsive force include:lower limb exoskeleton robot walking training,treadmill training combined with functional electrical stimulation,adaptive speed treadmill training,biofeedback technology,and whole-body vibration training.Among them,whole-body vibration training and biofeedback technology are more effective.The specific contributions and mechanisms of the hip,knee,and ankle joints in improving propulsive force are still controversial,but it is expected that the contributions of the hip and ankle joints are greater.Focusing on the improvement of propulsive force as a rehabilitation goal may yield more sustainable advancements in walking function.However,several current challenges persist in this field:understanding the neurobiological basis of propulsive force deficits in stroke patients,assessing the long-term efficacy of current rehabilitation techniques for enhancing propulsive force,and determining the most suitable patient populations for the application of major rehabilitation techniques aiming at improving propulsive force.These areas require further exploration by subsequent researchers.

Objective To optimize the method of combining azomethane oxide(AOM)and dextran sodium sulfate(DSS)to create a colitis-associated colon cancer(CAC)model,and to explore the pathogenesis of the intestinal flora in CAC.Methods Model groups A and B were established by one and two injections of AOM,respectively,combined with free drinking of DSS,and a normal control group was injected intraperitoneally with normal saline combined with purified water(n=10 mice per group).The better modeling scheme was selected by comprehensive evaluation of the disease activity index score,colon length,tumor rate,and mortality.Serum levels of interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),and tumor markers CA199,CEA,and CA724 were detected by enzyme-linked immunosorbent assay.Colon lesions were evaluated by hematoxylin and eosin(HE)staining.Changes in the intestinal microbiota in CAC mice were detected by 16S rDNA high-throughput gene sequencing analysis of mouse feces.Results Both single and enhanced AOM injections combined with DSS induced CAC mice;however,colon growths were larger,more closely arranged,and their morphological size was more consistent in group B compared with group A,with a tumor-formation rate of 100%.IL-6 levels were increased in the model group compared with the normal group(P<0.05).TNF-α levels were increased in the model group compared with the normal group(P>0.05).The CA199 and CEA levels were also significantly increased(P<0.05),but CA724 levels were not.Infiltration of inflammatory cells in the colon detected by HE pathology was accompanied by high-grade intraepithelial tumor-like changes on the surface of the lumen.The diversity and abundance of intestinal bacteria were decreased in CAC mice compared with normal mice:phyla Verrucomicrobiota and Actinobacteriota were significantly increased(P<0.05),Bacteroidota and Campilobacterota were significantly decreased(P<0.05).Akkermansia,Prevotellaceae,Ruminococcus,and Bifidobacterium were significantly increased(P<0.05),and Roseburia,Rikenellaceae_RC9_gut_group,Anaeroplasma,and Muribaculaceae were significantly decreased(P<0.05).Conclusions Two injections of AOM combined with 1.5%(1.5 g/100 mL)DSS induced CAC model mice with a high colon-tumorigenesis rate,uniform tumor morphology,and low mortality,and may thus be the preferred modeling scheme for pharmacodynamic experiments.Disorders or dysfunction of the intestinal flora may lead to increased permeability,loss of intestinal mucosal barrier function,and the release of enterogenic endotoxins,Resultsing in a sustained inflammatory response,as an indirect or direct cause of CAC pathogenesis.

Objective To analyze the short-term survival and prognostic quality of life of patients with liver cirrhosis complicated by bacterial infection. Methods This study collected and analyzed 300 patients with liver cirrhosis complicated with infection who were hospitalized in the First Affiliated Hospital of Hebei North University, and followed up to discuss their survival and quality of life. Results In this study, the top two causes of infection were spontaneous bacterial peritonitis (60.67% of patients) and pneumonia (50.67% of patients). The second causes were urinary tract infections (15.33%), gastrointestinal infections (12.33%), and other causes. There was no statistically significant difference between male and female patients (P>0.05). In addition, the proportion of hospital infections was 71.00%, and there was no statistically significant difference between male and female patients (P>0.05). A total of 353 strains of pathogenic bacteria were isolated in this study (73.37% of patients with hospital infections). The distribution analysis of pathogenic bacteria showed that the highest proportion of ECO was 35.98%, followed by Klebsiella pneumoniae (18.98%). The distribution trend of 259 strains of pathogenic bacteria among hospital patients was consistent with that of all strains, and the difference was not statistically significant (P>0.05). Gram negative bacteria accounted for 79.60% (281/353) of all detected strains, of which Escherichia coli was mostly detected in patients with spontaneous bacterial peritonitis, Klebsiella Pneumoniae (KPN) and Pseudomonas aeruginosa (PAE) were mostly detected in patients with pneumonia, and Enterococcus (ENF) was mostly detected in patients with urinary tract infection; Among gram-negative bacteria, Staphylococcus epidermidis (SEP) and Staphylococcus aureus (SAU) are mostly found in patients with other infectious causes (blood flow infection, etc.) , and Streptococcus (STR) accounts for a high proportion in patients with Spontaneous bacterial peritonitis. In this study, 9 cases of death prognosis were detected during follow-up, and there was no statistically significant difference in the detection of death prognosis between different bacterial strains in both genders, as well as the difference in detection of death prognosis between hospital infections and out of hospital infections in both genders (P>0.05). There was no statistically significant difference in the detection of death prognosis between males and females due to different causes of infection, P>0.05. The quality of life scores of 291 surviving patients were compared between baseline and follow-up, indicating an increase in follow-up scores, especially in the dimensions of physiological function and physical pain. There was no statistically significant difference between different bacterial strains, infection causes, and hospital/non hospital infections (P>0.05) . Conclusion Spontaneous bacterial peritonitis and pneumonia are the main causes of infection that deserve special attention, and the main pathogens of infection are Gram negative bacteria. Targeted treatment and rehabilitation should be provided for patients with liver cirrhosis complicated by infection. At the same time, the proportion of hospital infections is relatively high, and attention should be paid to, prevention and control measures should be implemented as well.
