Acute pancreatitis(AP)is a common digestive disorder associated with moderate to high nutritional risks,necessitating timely nutritional support.Over the past five decades,medical nutrition therapy for AP has undergone a paradigm shift,transitioning from traditional fasting based on the"pancreatic rest theory"to the current emphasis on early enteral feeding to"awaken the gut."Currently,nutritional treatment has become a cornerstone of comprehensive AP management.The European Society for Clinical Nutrition and Metabolism(ESPEN),founded in 1980,is a leading professional organization dedicated to advancing research,clinical practice,and education in clinical nutrition and metabolism.To date,ESPEN has published five evidence-based guidelines on nutritional management in pancreatic diseases.This article reviews the evolution of AP nutritional therapy as outlined in these ESPEN guidelines,highlighting key recommendations and their clinical implications.

Panax quinquefolium, also known as American ginseng, is a perennial herb in the Araliaceae family. It has the effects of replenishing Qi and nourishing Yin, clearing heat and generating saliva. Additionally, it has protective effects on the nerves, improves myocardial ischemia and hypoxia, regulates metabolism, enhances the body's immunity, and is known as "green gold". However, with the development of the industry and the expansion of planting scales, P. quinquefolium faces serious disease issues that are difficult to prevent and control. Among these, root rot, often referred to as "plant cancer", is one of the most destructive plant diseases affecting the yield and quality of P. quinquefolium. P. quinquefolium root rot is caused by the fungi Fusarium(genus) and Ilyonectria(genus), which severely affect the root system and limit the production and quality of P. quinquefolium, thus restricting the development of the P. quinquefolium industry. In recent years, research on P. quinquefolium root rot has attracted significant attention and made some progress. However, the mechanisms of interaction between the root rot pathogens and the host plant remain unclear. This paper reviews the research progress on the pathogens, infection cycle, disease prevalence, pathogenesis, and biological control of P. quinquefolium root rot to provide prospects for future research, aiming to provide references for the in-depth study and effective control of root rot, and to promote the green and healthy development of the P. quinquefolium industry.

Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

Objective: To investigate risk factors and the nature of the outbreak of bacillary dysentery in Lhasa City, so as to customize targeted prevention and control measures. Methods: Using on site epidemiological investigation, the suspected, probable and confirmed cases of bacillary dysentery in one school and one kindergarten in Lhasa City from June 26 to July 1, 2022 were collected, and additional cases were identified through interview from school staffs and family members, reviewing morning examination records and tracking records of school illness related absence. A case control study was conducted to investigate suspicious meals and drinking raw water, and polymerase chain reaction (PCR) was performed to detect Shigella line nucleic acid fragment in the patients feces, anal swabs, retained food, and terminal water. Results: A total of 55 cases were found in two schools, with the prevalence rate of 15.41% in total and 16.71% in students ( n =53), 7.5% in staff ( n =2). The epidemic curve was suggestive of a point source exposure. The prevalence rate among students who walk to school and students who live in the school showed no difference (16.10%，17.09%)( χ 2=0.05, P >0.05), and the prevalence rate was higher among elementary school students than kindergarten students (19.83%，6.67%)( χ 2=7.13, P <0.05). Case control comparisons showed a direct association between drinking raw water and morbidity in the case and control groups during June 24-26 ( OR=4.01, 95%CI =1.75-9.19, P < 0.05). A total of 23 fecal Shigella nucleic acid positives were detected from the two schools, two from the end water in front of the cafeteria door, and two from sludge in the sewage pipe around the wellhead. Conclusions The outbreak of bacillary dysentery is caused by the contamination of the pipe network water. Health administrative departments should improve the supervision and management of drinking water health safety, and schools should strengthen the management of water supply facilities for effectively prevent of waterborne infectious disease outbreaks.

This study investigated the prevalence of Borrelia burgdorferi,Anaplasma phagocy tophilum,Rickettsia typhi,Orientia tsutsugamushi,Leptospira interrogans,Francisella tularensis,and Babesia spp.in small mammals in the Qinghai plateau region,to provide a scientific basis for the prevention and control of local zoonotic diseases.Small mammals were cap-tured with snap traps at six sampling sites in the Qinghai plateau region.Liver,spleen,and kidney tissues were collected for detection of six bacterial pathogens with real-time PCR.Conventional PCR(cPCR)was used for Babesia detection,and the positive PCR products were sequenced and analyzed.The differences in pathogen detection rates among species and habitats were analyzed with x2 test or Fisher's exact test.In to-tal,235 small mammals from 15 species were captured.B.burgdorferi,L.interrogans,and Babesia were detected in 11 spe-cies of small mammals,whereas A.phagocytophilum,R.typhi,O.tsutsugamushi,and F.tularensis were not detected.B.burgdorferi was detected in 41 small mammals from nine species(Cricetulus longicaudatus,Apodemus peninsulae,Ochotona curzoniae,Mus m usc ulus,Meriones meridians,Microtus arvalis,Cricetidae,Ochotona cansus,and Allactaga sibirica),with an infection rate of 17.45％(41/235).L.interrogans was detected in eight small mammals from four species(C.longicaudatus,M.musculus,M.arvalis,and Microtus oeconomus),with an infection rate of 3.40％(8/235).Babesia was detected in only one Mustela altaica,with an infection rate of 0.85％(1/235).Statistically significant differences were ob-served in the detection rates of pathogens among small mammal species(x2=200.54,P＜0.05).Among habitats,the detection rate of B.burgdorferi was highest in the forest(Fisher's exact test,P＜0.05).B.burgdorferi and L.interrogans co-infection was observed in three M.arvalis and two C.longicaudatus.In addition,one Babesia sequence was obtained,which clustered with Babesia vulpes in the phylogenetic tree.B.burgdorferi,L.interrogans,and Babesia were the main pathogens prevalent in small mammals in the Qinghai plateau region and have potential to cause human diseases.Local authori-ties should strengthen the surveillance of corresponding zoonotic diseases,and formulate corresponding prevention and control measures.

Total hip arthroplasty(THA)is an effective treatment for elderly femoral neck fractures,mid-to late-stage femoral head necrosis,and end-stage hip osteoarthritis.However,serious complications such as aseptic loosening of the prosthesis,peripheral fractures,and dislocation of the prosthesis still exist following THA,which makes the selection of the appropriate hip prosthesis type and placement position before THA an important challenge for surgeons.Currently,the commonly used preoperative planning methods for THA mainly rely on static images from two-dimensional(2D)X-ray or three-dimensional(3D)computed tomography(CT),which fail to adequately consider the hip joint in weight-bearing as well as motion,lumbar-hip joint changes,and prosthetic impingement during motion.Recently,the dual fluoroscopic imaging system,as a new in-vivo,dynamic radiological imaging technology,provides comprehensive and accurate dynamic 3D data for THA preoperative planning.However,the technical process and expert consensus on preoperative 3D planning of THA using a dual fluoroscopic imaging system have not yet been established,which affects the promotion and application of this technology.In light of the above,national orthopaedic experts and related professional representatives discussed and proposed seven consensus issues,and the'expert recommendation rate'and'strong recommendation rate'were obtained through a questionnaire survey on the recommendations of the participating experts.This consensus aims to provide guidance and reference for the standardised application of preoperative 3D planning of THA using the dual fluoroscopic imaging system.

Objective To predict the intervention targets of empagliflozin(EMPA),a specific inhibitor of sodium-glucose cotransporter 2(SGLT2),in gastric adenocarcinoma through comprehensive network pharmacology,and to validate the effects and the molecular mechanisms of EMPA through cellular and molecular biology experiments.Methods Bioinformatics analysis of gastric adenocarcinoma was conducted to assess the correlation between gastric adenocarcinoma prognosis and SGLT2 expression.Network pharmacology was utilized to identify shared targets of EMPA and gastric adenocarcinoma.AGS cells,a human gastric adenocarcinoma cells line,were incubated with EMPA at different concentrations for 24 h and,then,cell proliferation was assessed using the CCK8 assay.After AGS cells were incubated with EMPA at the doses of 0,3,and 6 mmol/L,real-time cell analysis(RTCA)and 5-ethynyl-2-deoxyuridine(EdU)incorporation were used to evaluate EMPA's inhibitory effects on the proliferation of the AGS cells.In addition,wound healing and Transwell assays were performed to assess the inhibitory effect of EMPA on the migration and invasion of the APC cells and Western blot analysis was conducted to examine the expression of mammalian target of rapamycin(mTOR)and phosphorylated mTOR(p-mTOR).BALB/c(nu/nu)nude mice were implanted with 5x106 AGS cells in the axilla.The mice were divided into three groups,a control group,a low-dose group,and a high-dose group,each consisting of 7 mice.After one week,the control group received daily intraperitoneal injections of normal saline,while the low-dose group and high-dose group received daily intraperitoneal injections of EMPA at the doses of 3 mg/kg and 5 mg/kg,respectively.The tumor volume was measured one week after the drug intervention started.Results Gastric adenocarcinoma patients with low expression of SGLT2 exhibited longer survival time and higher survival rate than those with high expression of SGLT2 did.A total of 104 EMPA-related potential targets and 2028 targets associated with gastric adenocarcinoma were identified.Among these,45 targets associated with gastric adenocarcinoma overlapped with potential targets of EMPA.Further analysis revealed 10 relevant pathways and 4 core genes.The core genes were cyclin-dependent kinase 4(CDK4),glyceraldehyde-3-phosphate dehydrogenase(GAPDH),mTOR,and cyclin El(CCNE1).CCK-8 assay revealed that EMPA at concentrations ranging from 0.39 to 50 mmol/L effectively inhibited the proliferation of AGS cells.RTCA results indicated a downward shift in the cell growth curve.In comparison to the findings for the control group,EdU assay demonstrated that EMPA at the concentrations of 3 mmol/L and 6 mmol/L significantly inhibited AGS cell proliferation(P＜0.05).Results from wound healing and Transwell assays indicated a decrease in the levels of cell migration and invasion(P＜0.05)and,notably,there was a significant difference between the high and low-dose EMPA groups(P＜0.05).Western blot showed no statistically significant difference in the expression of total mTOR protein between the groups.However,the expression of p-mTOR in the 3 mmol/L and 6 mmol/L EMPA groups decreased compared to that of the control group(P＜0.05),with the 6 mmol/L EMPA group exhibiting a more pronounced reduction(P＜0.05).Nude mice xenograft tumor experiment demonstrated that,compared to that of the control group,the tumor volumes in the EMPA-treatment groups were significantly reduced(P＜0.05),with the high-dose group showing a more pronounced reduction(P＜0.05).Conclusion EMPA inhibits the abnormal proliferation and migration of gastric adenocarcinoma cells,potentially through the modulation of mTOR protein activation.This study provides new potential medication and intervention targets for gastric adenocarcinoma treatment.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (M^pro) and papain like protease (PL^pro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851M^pro inhibitors and 205 PL^pro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both M^pro and PL^pro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of M^pro inhibitors and over 20% of PL^pro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 M^pro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.
