Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

BACKGROUND:Numerous scholars have previously researched certain greater tuberosity fractures and the procedures used to treat them.Few researchers,however,have studied the comminuted split fracture of the greater tuberosity of the humerus(Liu-Gang type IV)with rotator cuff tear in great detail. OBJECTIVE:To compare the clinical therapeutic effect of open repair position modified calcaneal plate combined with suture anchors and proximal humeral internal locking system(PHILOS)plate in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV). METHODS:Case data of 30 patients with comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)from May 2012 to May 2022 were retrospectively analyzed.They were divided into the modified calcaneal plate combined with suture anchor group(group A)and the PHILOS with#2 Johnson group(group B),with 15 cases in each group.Intraoperative blood loss,surgical time,and incision length of all patients were recorded.Pain visual analog scale score,Constant-Murley score,as well as shoulder joint abduction,forward flexion,external rotation,and dorsal expansion activities during the last follow-up(>1 year)were evaluated. RESULTS AND CONCLUSION:(1)The surgical incision length and operation time were shorter,and blood loss was less in group A than those in group B(P<0.05).(2)No significant difference in visual analog scale score and Constant-Murley score was detected between the two groups(P>0.05).(3)During the last follow-up,forward flexion in group A was better than that in group B(P<0.05).No significant difference in abduction,external rotation,and dorsal expansion was determined between group A and group B(P>0.05).(4)In terms of complications,there was 1 case of shoulder joint pain and discomfort in group A(7%),2 cases of subacromial impingement syndrome,2 cases of upward movement of nodules,and 2 cases of shoulder joint pain(40%)in group B.There were significant differences in complication rates between the two groups(P=0.031).(5)In summary,the modified calcaneal plate combined with suture anchors in the treatment of comminuted fracture of split-type greater tuberosity of humerus combined with rotator cuff tears(Liu-Gang type IV)could better restore the forward flexion function of the shoulder joint and has a small incision,less blood loss,shorter operation time and fewer complications.

Objective To explore the therapeutic mechanism of Modified Lugen Formula(Phragmitis Rhizoma,Cicadae Periostracum,Batryticatus Bombyx,Lonicerae Japonicae Flos,Glycyrrhiza,Menthae Haplocalycis Herba,Notopterygii Rhizoma et Radix,Puerariae Lobatae Radix,Bupleuri Radix)in treating influenza from the virus-host interaction interface.Methods The phytocompounds were first collected from the HERB database,and then potential active compounds were screened out by Lipinski's rules of five.The targets of active compounds were further predicted through the SwissTargetPrediction platform.Differentially expressed genes(DEGs)were determined from the human H1N1 influenza dataset GSE90732 available in the Gene Expression Omnibus database(GEO).H1N1-Homo sapiens-related protein-protein interactions(PPIs)were gathered from the Pathogen-Host Interaction Search Tool(PHISTO).The above mentioned bioinformatic datasets were integrated.Then a PPI network and a Formula-virus-host interaction network were constructed using Cytoscape.Functional enrichment analyses were performed by using R software.Finally,molecular docking was carried out to evaluate the binding activities between the key compounds and targets.Results A total of 1 252 active compounds,1 415 targets,951 influenza-related DEGs,and 10 142 H1N1-Homo sapiens-related PPIs were obtained.There were 72 intersection targets between the Modified Lugen Formula and influenza.Functional enrichment analyses showed that these targets are closely related to host defense and programmed cell death.The network topological analysis showed that active compounds in the Modified Lugen Formula,such as oleanolic acid,γ-undecalactone,and longispinogenin,regulate viral proteins M2,NA,NS1,and HA and/or the host factors HSP90AA1,NRAS,and ITGB1,thus exert therapeutic effect.Molecular docking results confirmed that these compounds had a good binding ability with the targets.Conclusion Multiple active ingredients in Modified Lugen Formula directly target influenza virus proteins and/or host factors,thereby play an anti-influenza role in multiple dimensions,including inhibiting virus replication,regulating host defense and cell death.This study provides a theoretical basis for further experimental analysis of the action mechanism of the Modified Lugen Formula in treating influenza.

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 To investigate the current status of frailty in patients on maintenance hemodialysis(MHD),and explore the correlation of frailty with anxiety and depression.Methods General information,clinical data and blood biochemical data of 101 cases who underwent MHD in Department of Nephrology,Shunde Hospital Affiliated to Jinan University from January 2023 to January 2024 were collected.FRAIL scale was applied to evaluate the frailty of the patients,and they were accordingly classified into frailty group and non-frailty group(including pre-frail and non-frail participants).Anxiety and depression were evaluated by GAD-7 and PHQ-9 scale.Univariate analysis and logistic regression were used to explore the association of frailty with anxiety,depression and other possible influencing factors.Results Among the 101 cases,29 cases(28.71%)were includedin frailty group and 72 cases(71.29%)in non-frailty group.There were 42 patients with depression(41.58%)and 25 with anxiety(24.75%).In the frailty group,the prevalence of depression was 65.52%and that of anxiety 55.17%.There were significant differences in age,grip strength,exercise,stroke and coronary heart disease,anxiety and depression,ferritin and CRP between the two groups(P＜0.01).Multivariate regression analysis showed that depression,anxi-ety,no exercise,stroke and high ferritin concentration were independent risk factors for frailty in MHD patients(P＜0.05).Conclusion In patients on MHD,frailty is closely associated with depression,anxiety,and lack of exercise,and stroke as well as high ferritin concentration are independent risk factors for frailty.

Objective To investigate the clinical efficacy of oblique lumbar interbody fusion(OLIF)combined with poste-rior percutaneous internal fixation in patients with lumbar spinal stenosis with or without redundant nerve roots(RNRs).Meth-ods A retrospective analysis of 92 patients with lumbar spinal stenosis treated by oblique lateral lumbar interbody fusion com-bined with posterior percutaneous internal fixation from June 2019 to June 2022 was performed.There were 32 males and 60 females,aged from 44 to 82 years old with an average of(63.67±9.93)years old.All patients were divided into RNRs positive group and RNRs negative group according to redundancy or not before operation.There were 38 patients in RNRs positive group,including 15 males and 23 females.The age ranged from 45 to 82 years old with an average of(65.45±10.37)years old.The disease duration was 24.00(12.00,72.00)months.There were 54 patients in RNRs negative group,including 17 males and 37 females.The age ranged from 44 to 77 years old with an average of(62.42±9.51)years old.The disease duration was 13.50(9.00,36.00)months.The general data of patients were recorded,including operation time,intraoperative blood loss and complications.The imaging parameters before and after operation were observed,including the number of stenosis segments,intervertebral space height,lumbar lordosis angle and dural sac area.The visual analogue scale(VAS)was used to evaluate the back and lower extremity pain,and the Oswestry disability index(ODI)was used to evaluate the activities of daily living.Results All patients were followed up for 8 to 18 months with an average of(11.04±3.61)months,and no complications were found during the follow-up period.The number of stenosis segments in RNRs positive group(1.71±0.46)was more than that in RNRs negative group(1.17±0.38).In RNRs positive group,intervertebral space height,dural sac area,low back pain VAS,lower extremity pain VAS,ODI score were(1.11±0.19)cm,(0.46±0.17)cm2,(5.39±1.00)scores,(5.05±1.01)points,(55.74±4.05)points,respectively.RNRs negative groups respectively(0.97±0.23)cm,(0.69±0.26)cm2,(4.50±0.77)scores,(4.00±0.58)scores,(47.33±3.43)％.In RNRs positive group,intervertebral space height,dural sac area,low back pain VAS,leg pain VAS,ODI score were(1.60±0.19)cm,(0.74±0.36)cm2,(3.39±0.72)scores,(3.05±1.01)scores,(46.74±4.82)scores,respectively.RNRs negative groups respectively(1.48±0.25)cm,(1.12±0.35)cm2,(3.00±0.82)scores,(3.00±0.82)scores,(37.67±3.58)％.The postoperative intervertebral space height,dural sac area,low back pain VAS score,lower extremity pain VAS and ODI score of the patients in the RNRs positive group and the negative group were signifi-cantly improved compared with those before operation,and the differences were statistically significant(P＜0.05).There were statistically significant differences in the number of stenosed segments,preoperative intervertebral space height,dural sac area,low back pain VAS,lower extremity pain VAS,and ODI between the two groups(P＜0.05).There were significant differences in postoperative intervertebral space height and postoperative ODI between the two groups(P＜0.05),but there was no significant difference in intervertebral space height before and after operation and ODI score before and after operation(P＞0.05).There were significant differences in operation time,intraoperative blood loss,postoperative dural sac area,difference of dural sac area before and after operation,postoperative low back pain VAS,difference of low back pain VAS score before and after oper-ation,difference of lower extremity pain VAS before and after operation between the two groups(P＜0.05).Conclusion OLIF combined with posterior percutaneous internal fixation has a good effect on patients with or without RNRs.Multi-segmental lumbar spinal stenosis and decreased dural sac area may lead to the occurrence of RNRs,and LSS patients with RNRs have more severe symptoms.LSS patients with RNRs have worse surgical outcomes than those without RNRs.

Duchenne muscular dystrophy (DMD) is a severe X-linked recessive genetic disorder caused by mutations in the DMD gene, making it one of the most common forms of hereditary muscular dystrophy. The DMD gene, which encodes dystrophin, is the largest known gene in the human genome. Mutations in the DMD gene are highly diverse, including exon deletions, duplications, point mutations, and small insertions or deletions, posing significant challenges for treatment. Currently, there is no cure for DMD, and existing treatment strategies focus primarily on symptom management, which cannot reverse or halt disease progression. Advances in biotechnology position nucleic acid drugs and gene therapies at the forefront of DMD treatment research. These treatments aim to restore dystrophin expression by repairing or replacing mutated genes, thereby improving muscle function or slowing muscle degeneration. Preclinical studies in animal models and early-phase clinical trials demonstrate promising efficacy and offer new hope for DMD patients. This review briefly outlines the pathological mechanisms and genetic characteristics of DMD before delving into recent progress in therapeutic strategies, with a particular focus on nucleic acid drugs (including antisense oligonucleotides for exon skipping therapy and translation readthrough inducers) and gene therapy approaches (including gene replacement therapy and gene editing). The development and application of these therapies not only provide new treatment options for DMD patients, but also offer valuable insights for addressing other genetic disorders. However, numerous challenges impede the clinical translation of DMD treatments. Future studies must optimize existing therapeutic strategies, improve their efficacy and applicability, and explore innovative approaches to deliver more effective and sustainable treatments for DMD patients.
