Hepatic encephalopathy is a difficult and critical disease with rapid progression and limited treatment methods in the field of liver disease， and it is urgently needed to make breakthroughs in its pathogenesis. Selection of appropriate prevention and treatment strategies is of great importance in delaying disease progression and reducing the incidence and mortality rates. This article reviews the theory of “turbid toxin pathogenesis” and related prevention and treatment strategies for hepatic encephalopathy in traditional Chinese medicine/Zhuang medicine， proposes a new theory of “turbid toxin pathogenesis”， analyzes the scientific connotations of “turbid”， “toxin”， and the theory of “turbid toxin pathogenesis”， and constructs the “four-step” prevention and treatment strategies for hepatic encephalopathy， thereby establishing the new clinical prevention and treatment regimen for hepatic encephalopathy represented by “four prescriptions and two techniques” and clarifying the effect mechanism and biological basis of core prescriptions and techniques in the prevention and treatment of hepatic encephalopathy， in order to provide a reference for the prevention and treatment of hepatic encephalopathy.

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: The prevalence of overweight and obesity among children and adolescents continues to rise, becoming one of the most serious global public health issues of the 21st century. Given the differing growth and development environments between urban and rural children, associated risk factors also vary. This study aims to explore the distribution characteristics and influencing factors of overweight and obesity among urban and rural primary and secondary school students in Hunan Province, providing scientific evidence for targeted interventions. METHODS: A stratified, randomized cluster sampling method was used to select participants. A total of 197 084 students from primary and secondary schools across 14 prefectures in Hunan Province underwent physical examinations and questionnaire surveys. Population and spatial distribution characteristics of overweight and obesity were analyzed. Spatial distribution maps and spatial autocorrelation analyses were conducted using ArcGIS. Multivariate Logistic regression was used to identify influencing factors for overweight and obesity. RESULTS: The overall overweight and obesity rates among students in Hunan Province were 14.7% and 10.9%, respectively. Both rates were higher in urban areas than in rural counties (16.0% vs 13.9% for overweight; 12.1% vs 10.2% for obesity). Among both urban and rural students, boys had higher rates of overweight and obesity than girls. Higher-grade students had a higher overweight rate but a lower obesity rate than lower-grade students. In urban areas, the overweight and obesity rates of Han Chinese primary and secondary school students are lower than those of ethnic minority students (both P<0.05). In rural areas, the obesity rate of Han primary and secondary school students is lower than that of ethnic students (P<0.05). Across cities and prefectures, urban overweight and obesity rates ranged from 14.7% to 18.7% and 8.4% to 20.6% respectively, while rural rates ranged from 10.9% to 17.2% and 6.6% to 13.7% respectively. Spatial autocorrelation analysis revealed high-value clusters of overweight/obesity in urban areas of Changde and Zhangjiajie, and in rural areas of Loudi, Huaihua, and Shaoyang. Multivariate Logistic regression showed that gender, school stage, ethnicity, frequency of fresh vegetable intake, and sleep duration were associated with overweight and/or obesity in both urban and rural students. In urban students, frequency of fried food and fresh fruit intake, breakfast habits, physical activity on weekdays and holidays, and screen time on computers were also significant. In rural students, TV viewing time and sedentary duration were additional relevant factors. CONCLUSIONS The situation of overweight and obesity among primary and secondary school students in Hunan Province remains concerning. Greater attention should be paid to regions with high-value clusters of overweight/obesity, and targeted interventions should be developed based on urban-rural differences in influencing factors.

OBJECTIVES: The detection rate of scoliosis among school-aged children has been rising annually, varying by region, and has become a major public health concern affecting both physical and mental health. Its onset is multifactorial, and early screening combined with targeted interventions can alter disease progression. This study aims to investigate the prevalence and influencing factors of scoliosis among primary and secondary school students in Hunan Province, providing scientific evidence for targeted prevention strategies. METHODS: A stratified, randomized cluster sampling method was used to select 281 401 students from 14 prefecture-level cities in Hunan Province for scoliosis screening, physical examination, and questionnaire survey. The chi-square test was used for group comparisons, and trend chi-square test analyzed differences in screening positive rate by age. A multilevel regression model was applied to identify influencing factors, and ArcGIS was used to visualize spatial distribution patterns of scoliosis. RESULTS: The overall screening positive rate for scoliosis among Hunan students was 1.61%. Urban areas had a significantly higher rate than rural counties (2.81% vs 0.98%; P<0.01). The rate was equal between boys and girls (1.61% each). Underweight students had a higher rate than those with normal weight, overweight, or obesity (P<0.01). Stratified by age, urban students aged 6-18 years consistently showed higher positive rates than rural peers (P<0.001). No significant gender differences were observed at most ages (all P>0.05), except at age 11, where the females had a higher rate (1.28% vs 1.02%; P=0.048). After age 11, underweight students exhibited significantly higher positive rates than those with normal or higher BMI(all P<0.05). Across all groups, urban/rural, male/female, underweight/normal/overweight/obese, the scoliosis rate increased with age. By region, the screening positive rate ranged from 0.38% to 3.36%, with the top three being Chenzhou (3.36%), Xiangtan (2.78%), and Hengyang (2.71%), while the lowest was Xiangxi Tujia and Miao Autonomous Prefecture (0.38%). Multilevel regression analysis revealed that age (OR=1.160, 95% CI 1.135 to 1.186) and urban residence (OR=2.497, 95% CI 1.946 to 3.205) were positively associated with scoliosis risk (both P<0.01). Conversely, female gender (OR=0.931, 95% CI 0.874 to 0.993), normal nutritional status (OR=0.751, 95% CI 0.671 to 0.840), overweight (OR=0.513, 95% CI 0.447 to 0.590), obesity (OR=0.418, 95% CI 0.358 to 0.489), and engaging in ≥ 60 minutes of moderate-to-vigorous physical activity 2 to 4 days (OR=0.928, 95% CI 0.865 to 0.996) or 5 to 7 days per week (OR=0.912, 95% CI 0.833 to 0.998) were negatively associated with scoliosis risk (all P<0.05). CONCLUSIONS The prevalence of scoliosis among primary and secondary school students in Hunan Province is relatively high and is significantly associated with age, gender, urban-rural status, nutritional condition, and physical activity frequency. Targeted interventions and enhanced monitoring in high-risk regions and populations are essential to prevent and control scoliosis.

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 explore the effect of nicotinamide transmethylase on intracellular reactive oxygen species(ROS)in iron death of hepatocellular carcinoma cells and its mechanism.Methods Methyl nicotinamide(MNA)expression in cells was detected using a tandem liquid chromatography-mass spectrometry.The average fluorescence intensity of ROS and lipid peroxidation was measured using a flow cytometer.Western blot was used to detect changes in the expression of human liver cancer cells(SK-Hep-1,Hep3B).Forty patients with primary hepatocellular carcinoma who received treatment in our hospital from March 2019 to February 2020 were selected as the study subjects,and their adjacent tissue samples and liver cancer tissue samples were collected.Immunohistochemical methods were used to detect the levels of nicotinamide N-methyltransferase(NNMT)and ROS in adjacent and liver cancer tissues.CCK-8 method was used to detect the survival activity of cells with different iron concentrations.Results The MNA levels in the liver cancer tissue group were higher than those in the adjacent tissue group(P<0.05).Compared with the adjacent tissue group,the average fluorescence intensity expression of ROS in the liver cancer tissue group increased,while the average fluorescence intensity expression of lipid peroxidation decreased(P<0.05).Compared with the adjacent tissue group,the expression levels of SK Hep-1 and Hep3B cells in the liver cancer tissue group increased(P<0.05).Compared with the control group,NNMT groups 2,10,20,and 25 μmol/L The cell survival activity level increased(P<0.05);Compared with the NNMT group,the iron inhibition group had different iron concentrations(2μmol/L,10μmol/L,20μmol/L,25μmol/L.The expression of cell viability decreased(P<0.05).Conclusion ROS mediated by nicotinamide methyltransferase can be guided to produce ROS and energy disorders,leading to increased tumor cell death.

Objective To study animal models of chronic fatigue syndrome and to provide a reference for improvements in related animal experimental method and models.Methods Using"chronic fatigue syndrome,animal model"and"chronic fatigue syndrome,animal model"as search terms,we searched in the China Knowledge,Wanfang,and PubMed databases from July 2000 to July 2023.We compiled the literature on animal models of chronic fatigue syndrome and analyzed the experimental method and models.Content relating to experimental animals,modeling method,positive drugs,and detection indexes was sorted,and a database was set up for statistics and analysis.Results A total of 155 articles were included from the validated literature;most of the experimental animals were male SD rats of specific-pathogen free grade and body weights of around 180～220 g.Most of the mice used were KM males of 18～22 g.The most commonly used positive drug was ginsenoside tablets;and the typical modeling method was"forced cold water swimming+chronic restraint".Testing indexes were mainly behavioral and included exhaustive swimming test,open field test,rat tail suspension test,Morris water maze test,and animal'behavioral cycle,and observations of the general state of the animals.Modeling cycles mostly spanned 14 days.The most frequently tested indexes were serum MDA,SOD,TNF-α,IL-1β,CORT,IL-2,IFN-γ,ACTH,GSH-Px,IgG,IgA,and IL-6.The remaining indicators were selected according to the research purpose and included spleen,thymus,and other organ indexes;morphological indicators detected by hematoxylin and eosin pathological staining;ultrastructural electron microscopy indicators;immunohistochemistry-related indicators,and related mRNA and protein expression indicators detected by fluorescence quantitative PCR and Western blot method.mRNA and protein expression indexes were determined via a variety of tests,but the frequency of their application was low.At present,animal models are mainly used to study the effects of interventions and the etiology and mechanisms of the disease.Conclusions The pathogenesis of chronic fatigue syndrome is still unclear,and animal models are mainly based on stress modeling with"forced cold water swimming+chronic restraint",which simulates the physical and mental fatigue states of humans.No standard criteria for the formation of animal models are available,and the evaluation of models is based on the application of a variety of behavioral experiments,individually or in combination.Objective evaluation indexes are mostly used to validate the etiology of the disease and evaluate the effectiveness of interventions.The result of various test indexes have shown that chronic fatigue syndrome may be related to inflammatory responses,neurological dysfunction,and mitochondrial dysfunction,and there may be abnormalities in immune function,energy metabolism,cell proliferation,and cell death.This summary is expected to provide a reference for researchers planning to employ these models and ideas for model refinements.

To analyze the existing method for obtaining animal models of hepatic encephalopathy and their clinical characteristics with a view to providing ideas for the establishment of animal models that are more in line with the clinical characteristics of Chinese and Western medicine.To search the Chinese Knowledge Network and Wanfang database,the keywords"hepatic encephalopathy","hepatic coma","animal",and"animal model"were used.For the Pubmed database,"hepatic encephalopathy","hepatic coma","animal model",and"animal"were used as search keywords.The literature on effective method of specific animal model preparation was collated and classified according to different modeling factors and method.The modeling method and characteristics were summarized,and the degree to which the animal models shared the clinical characteristics and symptoms of hepatic encephalopathy according to Chinese and Western medicine was assessed.The clinical match of the animal model was assigned and analyzed according to the clinical symptoms of hepatic encephalopathy in Chinese and Western medicine.There were 128 valid literature articles featuring 11 animal models obtained using 15 different modeling method.The highest degree of agreement with Western medicine was the CC14 oil solution intraperitoneal injection+gavage+ammonium chloride intraperitoneal injection model(92％),and the highest degree of agreement with traditional Chinese medicine was the CC14 oil solution intraperitoneal injection+ethanol aqueous solution self-drinking model(65％),but both lacked a combination of Chinese and Western medicine clinical characteristics.At present,animal models of hepatic encephalopathy that combine the characteristics of Chinese and Western medicine are lacking.Improving and refining the models to encompass the characteristics of both Chinese and Western medicine are expected to provide ideas for mechanism research and advance the clinical diagnosis and treatment of hepatic encephalopathy.
