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 study the fingerprint of Denghong buyang huanwu granules （DBHG）， screen the quality markers， and establish the method for content determination of active ingredients. METHODS HPLC method was adopted. The fingerprints of 10 batches of DBHG （S1-S10） were established by using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine （2012 edition）， and similarity evaluation was also performed. Traditional Chinese medicine pieces attribution analysis， cluster analysis （CA）， principal component analysis （PCA） and orthogonal partial least squares discriminant analysis （OPLS-DA） were conducted for common peaks， and quality biomarkers were screened based on variable importance projection （VIP） values＞1. The contents of 10 batches of samples were determined by the same HPLC method， such as salidroside， tyrosol， calycosin-7-O-beta-D-glucoside， scutellarin and calycosin. RESULTS A total of 25 common peaks were obtained in the fingerprints for 10 batches of samples and 6 common peaks were identified， i.e. salidroside， tyrosol， paeoniflorin， calycosin-7-O-beta-D-glucoside， scutellarin， calycosin. Their similarities were greater than 0.9， and 10 common peaks of them were unique components of Erigeron breviscapus. DBHG could be clustered into 2 categories by using CA and PCA； S4-S5， and S7 could be clustered into one category and other samples could be clustered into one category. The corresponding components of peaks 16 （scutellarin）， 12， 15 （calycosin-7-O-beta-D-glucoside）， 13 （paeoniflorin）， and 14 were quality markers. The average contents of salidroside， tyrosol， calycosin-7-O-beta-D-glucoside， scutellarin and calycosin were 1.64， 0.45， 0.31， 0.73， 0.15 mg/g in 10 batches of samples. CONCLUSIONS HPLC fingerprint for DBHG and a method for determining the contents of five active ingredients including salidroside are successfully established. Five quality markers have been screened. It can be used for the quality control of the preparation.

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.
