ObjectiveTo investigate the association of the single nucleotide polymorphism （SNP） of the insulin-like growth factor binding protein-3 （IGFBP3） gene at rs10225396 （A>G） locus with the susceptibility to hepatocellular carcinoma， as well as its potential molecular regulatory mechanisms， and to provide novel genetic biomarkers and a theoretical basis for early screening and precise targeted therapy for hepatocellular carcinoma. MethodsA total of 192 patients with hepatocellular carcinoma who were admitted to The Affiliated Hospital of Yanbian University and Yanbian Cancer Hospital from January 2009 to August 2016 were enrolled as experimental group， and 190 healthy individuals who underwent physical examination in Physical Examination Center of Yanbian Hospital during the same period of time were enrolled as control group. Peripheral blood samples were collected from all subjects， and after DNA was extracted from whole blood， the DNA samples meeting quality standards were sent to Beijing Genomics Institute Research Center Co.， Ltd.， for Mass ARRAY mass spectrometry， while genotyping was completed. The independent-samples t test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. A binary Logistic regression model was used to analyze the association of the SNP of the IGFBP3 gene at rs10225396 locus with the susceptibility to hepatocellular carcinoma， and odds ratio （OR） and 95% confidence interval （CI） were calculated to assess the risk of developing hepatocellular carcinoma in individuals carrying different genotypes. ResultsThere were two alleles （G and A） at the rs10225396 locus of the IGFBP3 gene， yielding the three genotypes of AA， AG， and GG， and its genotype distribution was consistent with the Hardy-Weinberg equilibrium （χ²=0.072， P=0.789）. The stratified genetic analysis showed that carriers of the IGFBP3 rs10225396 AA genotype had a significant increased risk of hepatocellular carcinoma among individuals of age <63 years， male sex， smoking history， drinking history， and the Chinese Korean population （all P<0.001）. The binary Logistic regression analysis showed that after adjustment for related risk factors in the codominant model， the population with genotype AG and GG had a significant reduction in the risk of hepatocellular carcinoma compared with the population with genotype AA （P<0.001）， and in the dominant model， the population with genotype AG+GG had a significant reduction in the risk of hepatocellular carcinoma compared with the population with genotype AA （P<0.001）. ConclusionThrough a genotyping analysis of hepatocellular carcinoma patients and healthy individuals in Yanbian Korean Autonomous Prefecture of Jilin Province， China， this study shows that genotype AA at rs10225396 locus of the IGFBP3 gene is significantly associated with the susceptibility to hepatocellular carcinoma， and this genotype can significantly increase the risk of developing hepatocellular carcinoma with the presence of specific risk factors， which provides a potential genetic marker for early screening and precise treatment of hepatocellular carcinoma.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective To investigate the relationship between the single nucleotide polymorphism of PPARG rs2290449 and the efficacy of combination therapy in sepsis patients with MODS.Methods 382 cases of sepsis with MODS were selected and divided into the effective group and the ineffective group,and a case-control study was conducted.PCR-RFLP and Sequenom MassARRAY were used to detect the genotype and allele frequencies of the loci.Unconditional Logistic regression was used to calculate odds ratio(OR)and 95％confidence interval(CI)to evaluate the efficacy of combination therapy for sepsis with MODS in patients with different genotypes.Re-sults There were G and A alleles in PPARG rs2290449 locus,GG、GA and AA genotype.Non-conditional Logis-tic regression analysis showed that compared with the GG genotype group,the GA genotype group had a significant correlation with the efficacy of combination therapy for sepsis with MODS(OR=0.449,95％CI=0.280-0.722,P=0.001).In the dominant model,there was a significant correlation between the GA+AA genotype and the effi-cacy of combination therapy compared with the GG genotype(OR=2.104,95％CI=1.332-3.321,P=0.001).After adjusting for confounding factors,unconditional Logistic regression analysis showed that compared with the GG genotype,the GA+AA genotype was significantly correlated with the efficacy of combination therapy in sepsis pa-tients with MODS(OR=2.307,95％CI=1.438-3.701,P=0.001).Stratified analysis showed that compared with the population carrying GG genotype,the population carrying GA+AA genotype was significantly correlated with the efficacy of combination therapy in sepsis with MODS in the stratified analysis of age,gender and ethnicity.Conclusion PPARG rs2290449 single nucleotide polymorphism is significantly correlated with the efficacy of com-bination therapy in sepsis patients with MODS in Yanbian area.

Objectives:This study aimed to analyze the clinical and molecular characteristics of carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection (BSI) in patients with hematological diseases and to explore prognostic risk factors.Methods:This retrospective study included patients with hematologic diseases with CRE BSI at the Institute of Hematology and Blood Diseases Hospital from January 2015 to December 2022. The clinical features, carbapenemase test results, antimicrobial treatments, and outcomes were analyzed.Results:A total of 120 patients developed CRE BSI. Escherichia coli (58/120, 48.3%) was the most prevalent Enterobacteriaceae, followed by Klebsiella pneumoniae (52/120, 43.3%). A total of 93 CRE strains were tested for carbapenemase, of which 75 strains produced carbapenemase (metalloenzyme: 51 strains; serine enzyme: 24 strains). The 30-day mortality rate after BSI was 24.2% (29/120). Univariate analysis revealed significantly lower mortality in patients treated with the ceftazidime-avibactam-containing regimen than in those treated with other antibiotics (7.8% vs 36.2%, P<0.001). Moreover, initiating active therapy within 24 h of BSI onset significantly reduced mortality (15.0% vs 33.3%, P=0.019). The proportion of patients with CRE colonization receiving active therapy within 12 and 24 h was significantly higher compared with patients without colonization (12 h: 14.5% vs 34.1%, P=0.012; 24 h: 40.8% vs 65.9%, P=0.008). Multivariate analysis revealed that septic shock ( HR=24.436, 95% CI 4.148 - 143.966, P<0.001) and pulmonary infection ( HR=9.346, 95% CI 2.718-32.140, P<0.001) were independent risk factors for death within 30 days. Appropriate therapy was initiated within 24 h ( HR=0.225, 95% CI 0.059 - 0.851, P=0.028), and treatment with the ceftazidime-avibactam-containing regimen ( HR=0.082, 95% CI 0.018-0.362, P=0.001) significantly reduced mortality. Conclusion:The prognosis of CRE BSI in patients with hematological diseases is poor. Timely, appropriate therapy and receipt of a ceftazidime-avibactam-containing regimen can improve survival and prognosis.

Catheters were placed in femoral vein in each group. The control group was injected with 1.1 mL/kg physiological saline; the model group was injected with 0.1 mL/kg oleic acid and then injected with 1.0 mL/kg normal saline to establish ARDS model; the treatment group was injected with 0.1 mL/kg oleic acid and then injected with 1.0 mL/kg penehyclidine hydrochloride. At 3 hours after the model was established, blood gas analysis was carried out in each group, oxygenation index (PaO2/FiO2) was calculated, and the levels of serum interleukins (IL-1, IL-6) were measured by enzyme linked immunosorbent assay (ELISA). Rats were sacrificed to harvest lung tissue, and the lung wet/dry ratio (W/D) was calculated; the morphological changes of lung tissue was observed under microscope; the superoxide dismutase (SOD) activity and malondialdehyde (MDA) levels were detected by colorimetry; the expression of tumor necrosis factor-α(TNF-α) in lung tissue was detected by immunohistochemical method. The correlations between lung W/D ratio and various indicators were analyzed using Pearson correlation test.Results Compared with the control group, PaO2/FiO2 in model group was significantly decreased, lung W/D ratio was significantly increased, serum IL-1, IL-6 levels and lung tissue MDA content were significantly increased, lung tissue SOD activity was significantly decreased; the alveolar space was filled with exudate, neutrophils and red blood cells, and there were obvious edema and broadening in pulmonary interstitial and alveolar under light microscope; the type Ⅱ alveolar epithelial cells were partly destroyed, accompanied by lamellar body degeneration and emptying phenomenon under electron microscope; and immunohistochemistry showed that the positive expression of TNF-α in lung tissue was significantly increased. Compared with the model group, PaO2/FiO2 in the treatment group was significantly improved [mmHg (1 mmHg = 0.133 kPa): 204.42±31.61 vs. 113.91±47.78,P < 0.05], the lung W/D ratio was significantly decreased (5.80±0.44 vs. 6.82±0.59,P < 0.01), serum IL-1, IL-6 levels and lung tissue MDA content were significantly decreased [IL-1 (μg/L): 18.38±0.28 vs. 20.04±0.39, IL-6 (μg/L): 12.64±0.67 vs. 14.28±1.33, MDA (nmol/mg): 3.95±0.28 vs. 5.17±0.29, allP < 0.05], the activity of SOD in lung tissue was significantly increased (U/mg: 48.75±2.41 vs. 45.09±1.69,P < 0.01), histological and pathological changes were significantly reduced, and the positive expression of TNF-α in lung tissue was significantly reduced [positive cell rate: (25.80±3.44)％ vs. (38.82±3.59)％,P < 0.01].Conclusion Penehyclidine hydrochloride can effectively improve the oxygenation, alleviate lung injury and reduce pulmonary edema in oleic acid induced ARDS rat by decreasing lung W/D ratio, inhibiting oxidative stress and inflammatory response.

Objective To compare the clinical outcomes in elderly stroke patients with large artery atheroclerosis (LAA) and those with cardiogenic embolism (CE)-induced large vessel occlusion (LVO).Methods One hundred and twenty-two ≥65 years old sroke patients with LVO who underwent CT angiography or MR angiography in our hospital from June 2013 to June 2017 were divided into LAA group (n=62) and CE-induced LVO group (n =60) according to the TOAST Classification.Their NIHSS scores on admission and after discharge,good outcome after 3 months of stroke,recurrence rate and mortality of stroke were recorded and compared.Results No significant difference was found in the recurrence rate and mortality of stroke between the two groups (P＞0.05).The good outcome rate was significantly higher while the NIHSS score at discharge was significantly lower in CE-induced LVO group than in LAA group (33.33％ vs 17.74％,P=0.048;10.50±1.24 vs 11.83±1.53,P=0.001).No significant difference was found in the occlusion sites between the two groups (P＞0.05).Conclusion The recovery of neurological function is poorer in stroke patients with LVO than in those with CE-induced LVO.However,no significant difference can be found in the recurrence rate and mortality of stroke between the two groups.

Objective To investigate the relationship between the rat depression behaviors induced by chronically unpredicted stress (CUS) with interleukin-1β (IL-1β),interleukin-6 (IL-6) protein expression and indole-2,3-dioxygenase (IDO) mRNA and protein expression.Methods Thirty male Sprague Dawley (SD)rats were divided into the control group (CG) and model group (MG).The solitary raise combined with CUS 28 d continued stimulus was used to establish the rat depression model.The open field test (OFT) and the force swimming test (FST) were used to evaluate the rat depression behaviors;qRT-PCR was used to determine the mRNA expression of IDO in hippocampus and cortex;Western blot was used to determine the protein expressions of IL-1β,IL-6 and IDO in hippocampus and cortex.Results Compared with the CG group,the OFT score in the rats of the MG group was significantly decreased(P＜0.01),the immobility time in FST was significantly extended (P＜0.00),the expression of IDO mRNA in hippocampus and cortex was significantly increased (P＜0.01) and the protein expression of IL-1β,IL-6 and IDO in hippocampus and cortex was significantly increased (P＜0.05).Conclusion The rat depression behaviors induced by CUS may be associated with the increase of intracerebral inflammatory cytokine expression and inducing IDO over-expression.

Aim To study the role of histone acetyla-tion and its involvement in the depression-like behav-iors of rats induced by chronic unpredictable stress (CUS ). Methods Thirty male Sprague Dawley (SD ) rats were randomly divided into control group and model group.The method of solitary condition with CUS for consecutive 28 days was used to establish the rat depression model.The open-field test (OFT)and the forced swimming test (FST)were used to evaluate the depressive behaviors of rats;the real time PCR was used to detect the change of HDAC2 mRNA, and Western blot was used to determine the protein expres-sions of H3,H4,acH3 and acH4 in the prefrontal cor-tex and hippocampus of rats.Results Model group showed obvious depression-like behaviors with decrea-sing locomotive activity in OFT (P <0.01 )and in-creasing immobility time in FST (P<0.01),up-regu-lating the mRNA and protein expression of HDAC2 (P<0.0 1 ),and down-regulating the protein expression of acH3 and acH4 (P<0.01)in the prefrontal cortex and hippocampus significantly,compared with control group.Conclusion The mechanism of depressive be-haviors of rats induced by CUS may be associated with down-regulating the level of histone acetylation modifi-cation.

Aim To investigate the relationship be-tween the depression-like behaviors of rats induced by chronically unpredictable stress( CUS) and the protein expression of tumor necrosis factor alpha( TNF-α) , in-dole-2 , 3-dioxygenase ( IDO ) and 3-hydroxyl amino acid oxygenase( HAAO) . Methods Thirty male Spra-gue Dawley( SD) rats were randomly divided into con-trol group and model group. CUS plus solitary condi-tion were used to establish the depression model. The open field test ( OFT ) and the force swimming test ( FST ) were used to evaluate the depression-like behaviors of rats ;Western blot was used to determine the protein expressions of TNF-α, IDO and HAAO in the prefrontal cortex and hippocampus of rats. Results Model group rats showed obvious depression-like be-haviors with increasing immobile time in FST ( P <0. 01) and decreasing locomotive activity in OFT( P<0. 01 ) , and up-regulating the protein expression of TNF-α, IDO and HAAO in the prefrontal cortex and hippocampus significantly ( P <0. 05 ) , compared with control group rats. Conclusion The depression-like behaviors of rats induced by CUS may be associated with the activation of IDO-HAAO pathway mediated by TNF-α.
