AIM: To investigate variation patterns of corneal biomechanical parameters and binocular symmetry among children of different genders aged 8-16 years.METHODS:A retrospective study was conducted, and children who underwent optometric examinations at the ophthalmology department of our hospital were enrolled between January 2022 and December 2024. Measurements included the flat keratometry(K1), steep keratometry(K2), and mean curvature(Km)of the anterior corneal surface, horizontal visible iris diameter(HVID), central corneal thickness(CCT), corneal endothelial cell density(CECD), average cell size(ACS), coefficient of variation(CV), and hexagonality(HEX). Corneal parameters and binocular differences were compared between genders and across age groups.RESULTS:A total of 621 children(1 242 eyes)were enrolled in this study, including 284 males(568 eyes), 337 females(674 eyes), 528 children aged 8-12 years(1 056 eyes), and 93 children aged 13-16 years(186 eyes). In children aged 8-16 years, the K1, K2, Km and CV of both eyes, as well as the interocular CCT differences in boys were significantly lower than those in girls(all P<0.05), while the HVID and HEX of both eyes, as well as the CCT of the left eye in boys were significantly higher than those in girls(all P<0.05). Children aged 8-12 years had significantly higher K1, Km, CECD and HEX in both eyes, and significantly lower ACS in both eyes than those aged 13-16 years(all P<0.05). K1, K2, Km, CECD and HEX in both eyes were negatively correlated with age(P<0.05); ACS in both eyes was positively correlated with age(P<0.001); K1 and Km of the right eye were positively correlated with the CECD of the right eye(P<0.05), and K1 and CCT of the left eye were positively correlated with the CECD of the left eye(P<0.05).CONCLUSION:Significant gender differences exist in corneal parameters among children aged 8 to 16 years, while binocular symmetry remained stable.

OBJECTIVE To investigate the prevalence and influencing factors of potentially inappropriate medication （PIM） among the elderly in nursing homes in Urumqi based on three PIM screening tools， and to compare the applicability of different tools. METHODS A cross-sectional study design was adopted. Elderly individuals from six nursing homes in Urumqi were selected as the research subjects from May 2021 to September 2023. Demographic characteristics， disease burden and medication records of the elderly were collected. PIM screening was performed using the Chinese PIM criteria （2024 edition）， the American Geriatrics Society （AGS） Beers criteria （2023 edition）， and the Screening Tool of Older Person’S Prescriptions（STOPP）/Screening Tool to Alert to Right Treatment（START） （2023 edition）. Fleiss’s Kappa test was used to assess the consistency among the three screening tools， and multivariate Logistic regression was used to analyze the influencing factors of PIM. RESULTS The prevalence of PIM screened by the Chinese PIM criteria was 47.4% （323/682）， by the AGS Beers criteria was 43.4% （296/682）， and by the STOPP criteria was 50.9% （347/682）. The consistency among the three screening tools was low （Fleiss’s Kappa＝0.12， P ＜0.001）. Multivariate Logistic regression analysis showed that all three screening tools indicated that polypharmacy， aspirin use and psychotropic drug use were independent risk factors for PIM among elderly in nursing houses （all OR＞1， P ＜0.05）. CONCLUSIONS The prevalence of PIM among the elderly in nursing homes in Urumqi is relatively high. Polypharmacy， aspirin use and psychotropic drug use are common independent risk factors for PIM. There are differences in screening results among the three tools with low consistency. The Chinese PIM criteria can serve as a first-line tool for PIM screening in nursing homes.

ObjectiveTo investigate the protective effect of Xielitang on dextran sulfate sodium （DSS）-induced ulcerative colitis （UC） mice and its possible mechanism. MethodsDSS was used to establish UC model. Sixty mice were randomly divided into a normal group， a model group， a sulfasalazine group （0.6 g·kg^-1）， and low-， medium-， and high-dose Xielitang groups （1.67， 3.34， 6.68 g·kg^-1）. After treatment for 42 d， the colon length was recorded， and the disease activity index （DAI） score was calculated. Enzyme-linked immunosorbent assay （ELISA） was used to detect the serum levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-10 （IL-10）. Hematoxylin-eosin （HE） staining was used to observe the pathomorphological changes of colon. Western blot was used to detect the protein expression of farnesoid X receptor （FXR）， small heterodimer partner （SHP）， liver receptor homolog-1 （LRH-1）， cholesterol 7α-hydroxylase （CYP7A1）， and fibroblast growth factor receptor 4 （FGFR4） in liver and FXR， sodium-dependent bile acid transporter （ASBT）， and fibroblast growth factor 15 （FGF15） in ileum. 16S rRNA sequencing was used to analyze the intestinal flora. Moreover， ultra-high performance liquid chromatography–tandem mass spectrometry was used to detect the bile acid content. ResultsCompared with the normal group， the model group showed significantly decreased colon length， IL-10 content， α-diversity index， abundance of Firmicutes and Lactobacillus， and content of deoxycholic acid （DCA） and lithocholic acid （LCA） （P<0.01）， significantly increased DAI score， IL-6 and TNF-α content， abundance of Bacteroidetes， and the content of cholic acid （CA）， chenodeoxycholic acid （CDCA）， and taurocholic acid （TCA） （P<0.05， P<0.01）， significantly down-regulated protein expression of FXR， SHP， and FGFR4 in liver and FXR， ASBT， and FGF15 in ileum （P<0.01）， and significantly up-regulated protein expression of LRH-1 and CYP7A1 in liver （P<0.01）. In addition， the structure of colonic mucosa was destroyed， and inflammatory cells infiltrated in the model group. Compared with the model group， Xielitang could significantly increase the colon length， IL-10 content， α-diversity index， the abundance of Firmicutes and Lactobacillus， and DCA and LCA content （P<0.05， P<0.01）， decrease DAI score， abundance of Bacteroidetes， and the content of IL-6， TNF-α， CA， CDCA， and TCA （P<0.01）， up-regulate the protein expression of FXR， SHP， and FGFR4 in liver and FXR， ASBT， and FGF15 in ileum （P<0.01）， and down-regulate the protein expression of LRH-1 and CYP7A1 in liver （P<0.01）. The pathological damage of colonic mucosa was obviously alleviated. ConclusionXielitang protects against UC probably by regulating the "intestinal microbiota-bile acid" axis， regulating intestinal flora imbalance， and maintaining bile acid homeostasis.

ObjectiveINF2 is a member of the formins family. Abnormal expression and regulation of INF2 have been associated with the progression of various tumors, but the expression and role of INF2 in hepatocellular carcinoma (HCC) remain unclear. HCC is a highly lethal malignant tumor. Given the limitations of traditional treatments, this study explored the expression level, clinical value and potential mechanism of INF2 in HCC in order to seek new therapeutic targets. MethodsIn this study, we used public databases to analyze the expression of INF2 in pan-cancer and HCC, as well as the impact of INF2 expression levels on HCC prognosis. Quantitative real time polymerase chain reaction (RT-qPCR), Western blot, and immunohistochemistry were used to detect the expression level of INF2 in liver cancer cells and human HCC tissues. The correlation between INF2 expression and clinical pathological features was analyzed using public databases and clinical data of human HCC samples. Subsequently, the effects of INF2 expression on the biological function and Drp1 phosphorylation of liver cancer cells were elucidated through in vitro and in vivo experiments. Finally, the predictive value and potential mechanism of INF2 in HCC were further analyzed through database and immunohistochemical experiments. ResultsINF2 is aberrantly high expression in HCC samples and the high expression of INF2 is correlated with overall survival, liver cirrhosis and pathological differentiation of HCC patients. The expression level of INF2 has certain diagnostic value in predicting the prognosis and pathological differentiation of HCC. In vivo and in vitro HCC models, upregulated expression of INF2 triggers the proliferation and migration of the HCC cell, while knockdown of INF2 could counteract this effect. INF2 in liver cancer cells may affect mitochondrial division by inducing Drp1 phosphorylation and mediate immune escape by up-regulating PD-L1 expression, thus promoting tumor progression. ConclusionINF2 is highly expressed in HCC and is associated with poor prognosis. High expression of INF2 may promote HCC progression by inducing Drp1 phosphorylation and up-regulation of PD-L1 expression, and targeting INF2 may be beneficial for HCC patients with high expression of INF2.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Diabetic foot ulcer (DFU) have emerged as a serious global health issue due to its high rates of occurrence, disability, and mortality. DFU exhibit an exceptionally high recurrence rate, driven by a combination of behavioral and biological factors, leading to the recognition of fully epithelialized ulcers as being in "remission" rather than cured. However, the pathogenic factors underlying recurrent DFU (RDFU) remain poorly understood. This review examines the epidemiological characteristics and pathophysiological mechanisms of RDFU. Key mechanisms include neuropathy, angiopathy, epigenetic modifications, and metabolic memory. Research demonstrates that RDFU development results from the interplay of multiple factors: hyperglycemia-induced metabolic abnormalities, chronic inflammatory responses, vascular and neurological damage, as well as dysregulated epigenetic control. These factors interact synergistically, creating a vicious cycle that increases the risk of recurrence and delays recovery. By synthesizing current knowledge, this review aims to provide a foundation for future research and clinical management of RDFU. The insights presented support the development of personalized treatment strategies and effective preventive measures to reduce recurrence and improve patient outcomes.

Objective To investigate the distribution characteristics and future trends of clinical trials related to TCM prevention and treatment of constipation by analyzing the clinical trials registered in the Chinese Clinical Trial Registry(ChiCTR).Methods The clinical trials data related to TCM prevention and treatment of constipation in the ChiCTR database were retrieved from the establishment of the database to April 15,2024.Excel 2019 was utilized for de-duplication.Subsequently,SPSS 26.0 was employed to analyze the general characteristics,research types,intervention measures,etc.of the included trials,charts were drawn,and the clinical trial characteristics were summarized.Results A total of 107 clinical trials were included,with 102 being pre-registered,involving 21 provincial-level administrative regions and 75 clinical institutions.The top five regions in terms of the number of registered clinical trials were Beijing(19.63%),Shanghai(15.89%),Guangdong(14.02%),Sichuan(10.28%)and Jiangsu(9.35%).The top three sources of funding were local finance(28.97%),self-raised funds(18.69%)and hospital-funded funds(15.89%).The research types were mostly intervention studies(92.52%),of which 41 explicitly stated the use of blinding methods,and the main research design type is randomized parallel controlled trial.Conclusion The number of clinical trials related to TCM prevention and treatment of constipation registered in ChiCTR is on an upward trend.However,there is a noticeable geographical imbalance in the distribution of these trials,and there is a need for further improvement in the quality of trial design and the standardization of registration information.

[Objective]To construct a prediction model for brucellosis by using a deep neural network algorithm to improve the early detection.[Methods]We collected the clinical data of 202 brucellosis patients and 319 non-brucellosis patients admitted to Hohhot Occupational Disease Prevention and Treatment Hospital in 2023,and analyzed data such as gender,age,blood routine indices and clinical diagnosis.A prediction model for brucellosis was constructed by using a deep neural network algorithm and optimized through 10-fold cross-validation.Performance metrics included sensitivity,false negative rate,specificity,false positive rate,accuracy,positive predictive value,negative predictive value,F1 score,and area under the receiver operating characteristic curve(AUC).The optimal model was interpreted by using SHapley Additive exPlanations(SHAP)to clarify decision-making logic and feature influencing mechanisms.[Results]Data visualization analysis revealed no significant difference between brucellosis and non-brucellosis groups.The optimal model demonstrated good performance:sensitivity(85.3%),specificity(92.1%),accuracy(89.5%),AUC(96.6%),95%CI(0.937,0.977).SHAP analysis identified age,platelet count,mean platelet volume,basophil ratio,red blood cell distribution width,and absolute basophil count as significant predictors of brucellosis.[Conclusions]The deep neural network prediction model constructed in this study has good performance and can provide reliable support for the early diagnosis,prevention and control of brucellosis.Identification of key brucellosis-related influencing features will help further understand the pathogenesis of the disease,and this model holds promise for broad clinical application in the future.

Objective To investigate the clinical effect of simultaneous use of three endoscopes(laparoscope,choledochoscope,and duodenoscope)combined with holmium laser in the treatment of gallstones complicated with common bile duct stones.Methods A prospective randomized controlled study was carried out.A total of 80 patients with cholecystolithiasis combined with choledocholithiasis in our hospital from August 2022 to January 2024 were selected and divided into three-endoscope group(n=40)and two-endoscope group(n=40)according to random number table method.Patients in the three-endoscope group underwent laparoscopic cholecystectomy(LC)and laparoscopic common bile duct exploration(LCBDE)combined with holmium laser lithotripsy,primary closure of the common bile duct,endoscopic retrograde cholangiopancreatography(ERCP),and endoscopic nasobiliary drainage(ENBD),while the two-endoscope group underwent LC+LCBDE+T-tube drainage.The intraoperative bleeding volume,operation time,hospitalization time,hospitalization costs,and postoperative complications between the two groups were observed and analyzed.Results There was no significant difference in intraoperative bleeding volume between the two groups[(55.6±14.3)ml vs.(53.2±16.3)ml,t=0.703,P=0.484].The operation time of the three-endoscope group was significantly longer than that in the two-endoscope group[214.5(171.5,246.8)min vs.178.0(151.0,227.8)min,Z=-2.069,P=0.039].The length of hospital stay in the three-endoscope group was significantly shorter than that in the two-endoscope group[(13.2±3.3)d vs.(16.2±3.7)d,t=3.864,P=0.001].The hospitalization costs were significantly higher in the three-endoscope group than those in the two-endoscope group[39 316.0(32 338.5,43 421.0)yuan vs.33 717.0(30 873.3,37 813.3)yuan,Z=-3.272,P=0.001].There were no significant differences in the incidence of postoperative pancreatitis[2.5%(1/40)vs.2.5%(1/40),χ2=0.000,P=1.000],the incidence of bile leakage[7.5%(3/40)vs.2.5%(1/40),χ2=0.263,P=0.615],and residual stone rate[7.5%(3/40)vs.0.0%(0/40),P=0.241]between the two groups.Forty cases in the three-endoscope group were followed up for 2-20 months,with a median of 13 months.One case of stone recurrence occurred at 8 months after surgery.Forty patients in the two-endoscope group were followed up for 1-21 months,with a median of 15 months.There was 1 case of stone recurrence at 6 and 10 months postoperatively,respectively.There was no statistically significant difference in stone recurrence rate between the two groups[2.5%(1/40)vs.5.0%(2/40),χ2=0.000,P=1.000].Conclusions LC+LCBDE combined with holmium laser lithotripsy,primary closure of the common bile duct,ERCP,and ENBD in the treatment of cholecystolithiasis and choledocholithiasis can shorten the hospitalization time.The replacement of T-tube with nasobiliary duct protects the function of the Oddi sphincter,which is more in line with the concept of minimally invasive surgery and worthy of clinical application.
