This paper summarized the clinical experience of Prof. LI Diangui in treating gastroesophageal reflux disease (GERD) based on the theory of turbidity-toxin in liver. It is believed that internal accumulation of turbidity-toxin and liver depression with stomach counterflow are the main pathogenesis of GERD, and thus the therapeutic methods of resolving turbidity and resolving toxins, regulating the liver and harmonizing the stomach are proposed. In clinical practice, GERD is divided into the early stage, middle stage and late stage. For the early stage, the modified Huazhuo Shugan Hewei Formula (化浊疏肝和胃方) is used to regulate qi and remove turbidity, soothe the liver and harmonize the stomach; for the middle stage, the modified Huazhuo Qingre Zhisuan Formula (化浊清热制酸方) is applied to clear heat, direct the turbid downward, and resolve toxins; for the late stage, the modified Yiwei Decoction (益胃汤) is adopted to replenish qi, nourish yin and simultaneously resolve turbidity-toxin. Throughout the treatment process, attention should be paid to protecting the spleen and stomach, and the medication could be modified according to changes of individual condition.

Methods:
Data on hospitalized injury cases admitted between January to December 2022 were collected through the hospitalization registry system from 17 healthcare institutions in Huangpu District. The population distribution characteristics, causes of injury, injury sites, duration of hospital stay, and hospitalization costs were descriptively analyzed.
Results:
A total of 6 729 hospitalized injury cases were reported in Huangpu District in 2022, including 4 277 males and 2 452 females, with a male-to-female ratio of 1.74∶1. The average age was (49.57±19.82) years, with 2 064 cases (30.67%) aged 45 to <60 years and 1 921 cases (28.55%) aged ≥60 years. The median length of hospitalization was 9.00 (interquartile range, 11.00) days, with median hospitalization costs of 15 968.93 (interquartile range, 25 786.69) yuan. In the months of June to August, there were more cases of injury hospitalization,with 1 904 cases accounting for 28.30%. The top three causes of injury were falls (2 895 cases, 43.02%), transportation accidents (1 247 cases, 18.53%) and exposure to inanimate mechanical forces (1 104 cases, 16.41%). The top three injured sites were lower limb injuries (1 850 cases, 27.49%), upper limb injuries (1 596 cases, 23.72%) and other sites (1 178 cases, 17.51%). The three leading causes of injury with longest hospitalization duration were burns and scalds, transport accidents and falls, with the median duration being 12.00 (interquartile range, 8.00) days, 10.00 (interquartile range, 13.00) days and 10.00 (interquartile range, 11.00) days, respectively. The top three injury sites associated with the longest hospitalization duration were others, lower limb injuries, and head and neck injuries, with the median duration being 11.00 (interquartile range, 13.00) days, 11.00 (interquartile range, 11.00) days, and 10.00 (interquartile range, 12.00) days, respectively. The causes of injury associated with higher hospitalization costs were falls and transportation accidents, with the median hospitalization cost being 23 550.13 (interquartile range, 30 087.76) yuan for falls and 20 301.94 (interquartile range, 30 589.86) yuan for transportation accidents. The injury sites associated with higher hospitalization costs were lower limb injuries and upper limb injuries, with the median hospitalization cost being 24 257.32 (interquartile range, 34 145.54) yuan for lower limb injuries and 16 506.33 (interquartile range, 20 052.27) yuan for upper limb injuries.
Conclusions
In Huangpu District, hospitalized injury mainly occurred among males and individuals aged ≥45 years, with the higher incidence observed between June and August. Fall was the primary cause of injury, while lower limb injuries was the main injury sites. The injury resulted in substantially higher hospitalization costs.

OBJECTIVE:
To characterize a glycosyltransferase (RpUGT1) from Rheum palmatum and investigate its specificity toward flavonoid compounds.
METHODS:
The RpUGT1 was expressed in Escherichia coli and screened for catalytic activity against a range of flavonoid substrates using a high-throughput HPLC assay method. Mass spectrometry (MS) and nuclear magnetic resonance (NMR) were used to determine the structure of the product. Homology modeling, molecular docking analyses and site-directed mutagenesis studies were conducted to identify key residues responsible for its function.
RESULTS:
The recombinant RpUGT1 protein exhibited catalytic activity towards various flavonoids. Notably, RpUGT1 catalyzed the glycosylation of isorhamnetin to form 3-O-glucoside and kaempferol to form 7-O-glucoside, utilizing uridine diphosphate (UDP) glucose as the sugar donor. The homology modeling and molecular docking analyses identified key residues responsible for its activity. Subsequent site-directed mutagenesis studies highlighted the crucial role of K307 in catalysis.
CONCLUSION
These discoveries offer valuable perspectives on the role of the UGT family and establish a groundwork for forthcoming research on the synthesis of flavonoids in plants.

Objectives:To explore the spatial distribution characteristics, trend changes, and spatial clustering of esophageal cancer among residents in China at the county (city, district) scale, a spatial epidemiological approach was used, with the aim of providing localized evidence for the prevention and treatment of esophageal cancer in China.Methods:The data source was the incidence (crude rate) and mortality (crude rate) of esophageal cancer from 2005 to 2016 in the 2008-2019 edition of China Cancer Registration Annual Report published by the National Cancer Center. The Joinpoint model was used for time trend analysis. The tumor registration area in 2016 was selected as the study area for spatial feature analysis, with a total of 487 counties (cities and districts), covering 27.6% of the national population. Spatial autocorrelation analysis was performed to reveal spatial distribution characteristics by using Arcgis 10.6 software, and spatial scanning statistics was used to analyze spatial clustering characteristics by using SaTScan 9.5 software. The log-likelihood ratio ( LLR) and relative risk ( RR) were calculated in different windows, and the region with the largest LLR value represented the most likely cluster. Results:From 2005 to 2016, the incidence and mortality rate of esophageal cancer in China showed a trend of increasing at first and then decreasing. The incidence and mortality rate of esophageal cancer in 2016 were characterized by spatial positive correlation. High incidence and high mortality were mainly concentrated in the areas through which the Huaihe River flowed. The primary clusters (taking high incidence rate as an example LLR=6 374.41, RR=2.37, P<0.001) were mainly distributed in Jiangsu, Anhui and Shandong in eastern China and eastern Henan and southern Hebei in central China, and secondary clusters (taking high incidence rate as an example LLR=1 971.19, RR=1.91, P<0.001) in Gansu, Ningxia Hui Autonomous Region, Shaanxi, Sichuan and other central and western regions. Conclusions:The incidence and mortality of esophageal cancer in China have decreased since 2010. The disease burden of esophageal cancer has obvious spatial differences, and measures should be taken according to local conditions in high-risk cluster areas such as the Huaihe River basin.

Objective Based on the clinical characteristics of refractory epilepsy in traditional Chinese and Western medicine,this study compares the existing animal models of refractory epilepsy,evaluates the effectiveness and limitations of the models,and explores the integration of traditional Chinese and Western medicine theory and optimization of model construction.Our aim is to provide new research directions for elucidating the mechanism and prevention of refractory epilepsy.Methods By reviewing relevant literature and summarizing the available data,we examined current refractory epilepsy animal models,focusing on their replication methods,animal strains,as well as advantages and disadvantages of animal models.Based on the Western medicine diagnostic criteria and traditional Chinese medicine syndrome differentiation criteria for refractory epilepsy,the coincidence of existing animal models and clinical symptoms were analyzed and evaluated.Results Our review of existing refractory epilepsy animal models revealed that electrical and chemical kindling are common modeling methods.The lithium-pilocarpine model and the intrahippocampal kainic acid model show high congruence with the symptom characteristics of traditional Chinese and Western medical clinical diagnosis and are widely used.Existing models mostly focus on simulating the pathological changes of refractory epilepsy,while neglecting the factors such as congenital endowment and emotional disorders,which have been emphasized in traditional Chinese medicine.Therefore,there are still certain limitations in simulating the complexity of etiology,clinical heterogeneity,and drug treatment responsiveness of refractory epilepsy.Conclusion Although replicating animal models can reflect their pathogenesis to some extent,there are still significant differences between them and the natural pathological state and clinical manifestations of the body.The existing animal models of refractory epilepsy mostly use electrical stimulation or chemical drug induction,which has certain advantages in simulating epileptic persistence and drug resistance.However,there are still limitations such as a single induction method and insufficiently complex pathological changes.In the future,efforts can be made to integrate traditional Chinese medicine syndrome differentiation and conventional electrical stimulation or chemical drug induction methods.By simulating multiple pathogenic factors,a refractory epilepsy animal model covering different traditional Chinese medicine syndrome types can be established.At the same time,multi-dimensional indicators such as behavior,electrophysiology,imaging,and histopathology can be used to construct a more comprehensive evaluation system,in order to improve the clinical relevance and translational application value of the model.During the modeling process,liver depression syndrome models can be established through methods such as tail clamping,chronic restraint,and single cage feeding with neck shackle.A model of phlegm coagulation syndrome can be established using high-fat feed feeding method.A model of qi stagnation and blood stasis syndrome can be established using tail clip and adrenaline injection.A model of essence exhaustio due to kidney deficiency syndrome can be established by combining panic induced kidney injury with fatigue swimming.It is also possible to simulate changes of yin-yang in the environment by altering lighting and temperature conditions and study the impact of environmental changes on traditional Chinese medicine animal models.The aim of this study is to provide more ideas for the treatment and research of refractory epilepsy.
