Objective To analyze the relationship between cognitive function, motor ability and the risk of falls in patients during the rehabilitation period after stroke. Methods A total of 330 patients with stroke who received rehabilitation treatment in the hospital from February 2022 to February 2025 were classified into fall group (n=105) and non-fall group (n=225) based on the occurrence of falls during rehabilitation period. The clinical data of patients were collected, and the motor function of patients was evaluated by Fugl-Meyer scale, and the cognitive function of patients was assessed by mini-mental state examination (MMSE). Univariate and logistic multivariate regression analyses were applied to analyze the factors affecting the occurrence of falls. Spearman correlation analysis was performed to analyze the relationship between motor ability, cognitive function and risk of falls. Results The proportions of osteoporosis, malnutrition, sleep disorder and history of falls in the fall group were higher while the education level, Fugl-Meyer score and MMSE score were lower compared to the non-fall group (P<0.05). After logistic multivariate analysis, it was found that osteoporosis, malnutrition, sleep disorder, history of falls, low education level, low Fugl-Meyer score and low MMSE score were risk factors for falls in patients during post-stroke rehabilitation period (P<0.05). Correlation analysis indicated that the motor ability and cognitive function in patients during post-stroke rehabilitation period were negatively associated with the occurrence of falls (r=-0.579, -0.438, P<0.001). Conclusion The cognitive function, motor ability of patients in the post-stroke rehabilitation period are closely related to the risk of falls. Clinically, the risk of falls in patients during post-stroke rehabilitation period can be reduced by improving the motor ability and cognitive function.

According to different time points of the implementation of vaccination policies, cases born from January 1, 1992 to December 31, 2023 were divided into three groups: the group from January 1, 1992 to December 31, 2001 (94 194), the group from January 1, 2002 to May 31, 2005 (70 428), and the group from June 1, 2005 to December 31, 2023 (87 057). The general data and HBV serological markers results were collected for statistical analysis. The comparison of intergroup rates was conducted using the Chi-square test, and the trend test was conducted using the Cochran Armitage test. Results:In recent five years, the total positivity of serum hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e antigen (HBeAg), hepatitis B e antibody (HBeAb) and hepatitis B core antibody (HBcAb) were 6.68% (67 938/1 017 030), 51.69% (485 627/939 498), 2.37% (21 961/926 626), 15.00% (138 853/925 759) and 27.86% (257 344/923 703), respectively. According to gender, the total positivity of HBV serological markers in men was significantly higher than that in women, and the difference was statistically significant (HBsAg: χ 2=5 599.286, P<0.001; HBsAb: χ 2=5.065, P=0.024; HBeAg: χ 2=2 451.420, P<0.001; HBeAb: χ 2=1 066.145, P<0.001; HBcAb: χ 2=4 013.618, P<0.001). According to the age group, the peak of HBsAg positivity was mainly distributed in the age group of 41-50 years old, with a positivity of 10.48% (2 864/27 324). The positivity of HBsAb decreased with age.The positivity of HBsAb decreased with age increase, highest in the 0-10 years old group, and a decrese in the 11-20 years old group ( Z=18 915.453, P<0.001). The positivity of HBcAb increased with age ( Z=27 493.853, P<0.001). According to the regional groups, the positivity of HBsAg and HBeAg in Shenyang City were 5.01% (3 996/76 974) and 1.45% (944/69 117) respectively. The positivity of HBsAb in patients from Liaoyang district was the highest [55.89% (3 362/6 150)]. The highest positivity of HBeAb and HBcAb were in patients from Dandong district, 19.90% (3 362/6 150) and 37.37% (3 119/8 680) respectively. According to the different time points of the implementation of the vaccination policies, the positivity of HBsAg in cases born from June 1, 2005 and December 31, 2023 decreased to 0.30% (259/87 057) compared with cases born before this time point (χ 2=5 777.47, P<0.001). Conclusions:The analysis of HBV serological laboratory characteristics showed that the positivity of contagious HBV serological markers was still high. The positivity of male was higher than that of female. HBsAb levels decreased significantly in the 11-20 years old group, suggesting the necessity to strengthen hepatitis B prevention in this age group. There were regional differences in the prevalence of hepatitis B, suggesting the necessity to optimize and improve HBV prevention and control strategies.

Objective To compare the efficacy and safety of flexible ureteral lithotripsy(FURL)and non-retrograde percutaneous nephrolithotomy(NR-PCNL)for treating1.5-2.0 cm upper ureteral stones.Methods We retrospectively analyzed clinical data of 130 patients with upper ureteral stones treated between October 2022 and October 2024.Sixty-two patients underwent FURL and 68 underwent NR-PCNL.Comparisons included operative time,pre-and postoperative changes in white blood cells(WBC),hemoglobin(Hb),and creatinine(Cr),postoperative C-reactive protein(CRP)levels,stone-free rate after primary surgery,postoperative hospitalization duration,pain scores,complications,and need for auxiliary treatments.Results Compared to the FURL group,the NR-PCNL group demonstrated advantages in operative time[54.0(44.3,69.3)min vs.82.5(66.0,101.0)min,Z=-5.565,P<0.001],WBC elevation[1.9(0.5,3.5)×109/L vs.4.5(3.0,6.0)×109/L,Z=-4.528,P<0.001],and secondary surgery rate[0%(0/68)vs.14.5%(9/62),P<0.001].The FURL group showed lower Hb reduction[3.0(2.0,6.3)g/L vs.8.0(5.0,11.0)g/L,Z=-4.262,P<0.001],less postoperative Visual Analogue Scale(VAS)pain scores[1.0(1.0,2.0)points vs.2.0(1.0,2.0)points,Z=-2.840,P=0.005],and shorter hospitalization duration[2.0(1.0,2.0)d vs.3.0(2.0,3.0)d,Z=-5.815,P<0.001].No significant differences were observed in Cr elevation,CRP levels,stone-free rate after primary surgery,complications,or analgesic requirements(P≥0.05).Conclusions Both NR-PCNL and FURL are safe and effective for 1.5-2.0 cm upper ureteral stones.FURL offers better patient comfort,while NR-PCNL shows superior overall safety.

Objective:To explore the efficacy and prognosis of preoperative treatment based on arterial infusion chemotherapy (PTAC) in patients with advanced gastric cancer.Methods:Clinical and follow-up data of 821 patients with advanced gastric cancer who received PTAC treatment at the General Hospital of the Eastern Theater Command of the People's Liberation Army from January 2001 to January 2021 were collected. According to the treatment regimen, patients were divided into the FLEEOX group (89 cases), the XEEOX group (196 cases), the SEEOX group (406 cases), and the SEEOX+PD-1 group (130 cases). The primary endpoint was the 3-year progression-free survival rate. Secondary endpoints included the 3-year overall survival rate, objective response rate, radical resection rate, major pathological response rate, and incidence of treatment associated adverse events.Results:After PTAC treatment, the objective response rate was 74.9% (615/821). A total of 671 patients underwent radical surgery, with a radical resection rate of 81.7% and an R0 resection rate of 70.2% (576/821). The pathological complete response rate was 16.7% (112/671), and the major pathological response rate was 32.2% (216/671). With an average follow-up of 27.7 months, the 3-year progression-free survival rate was 52.2%, and the 3-year overall survival rate was 55.8%. The 3-year progression-free survival rate of patients in the SEEOX+PD-1 group was 66.9%, the objective response rate was 83.8% (109/130), the major pathological response rate was 45.3% (53/117), and the radical resection rate was 90.0% (117/130), all of which were better than those in the XEEOX and SEEOX groups (all P＜0.05). However, during the treatment period, three patients in the SEEOX+PD-1 group died from immune-related adverse events. Conclusion:PTAC treatment is an effective preoperative treatment method for advanced gastric cancer, and is expected to further improve the treatment effect when combined with immunotherapy such as PD-1 monoclonal antibodies.

Objective:To investigate the effects of phillyrin(PHN)on the proliferation,invasion,and epithelial-mesenchymal transition(EMT)of glioma U251 cells by adjusting the high mobility group protein B1(HMGB1)/receptor of advanced glycation endproduct(RAGE)signaling pathway.Methods:Human glioma U251cells were assigned into the PHN-0 group(treated with 0 μmol/L PHN),the low,medium,and high-dose PHN groups(PHN-50、PHN-100、PHN-200 groups,treated with 50,100,and 200 μmol/L PHN respectively),the PHN+pcDNA-NC group(treated with 200 μmol/L PHN after transfection of pcDNA-NC plasmid),and the PHN+HMGB1 group(treated with 200 μmol/L PHN after transfection of overexpressed HMGB1 plasmid).The proliferation ability of cells in each group was detected by the CCK-8 method and the clone formation assay.The apoptosis level of cells in each group was detected by flow cytometry.The migration and invasion abilities of cells in each group were detected by the Transwell assay.ELISA was used to detect the IL-8 secretion level of cells in each group.Immunofluorescence was used to detect the positive rates of N-cadherin and E-cadherin in cells of each group.WB assay was performed to detect the expression levels of Toll like receptor 4(TLR4),nuclear factor-kappa B(NF-κ B),HMGB1,RAGE,N-cadherin,E-cadherin,cell cycle protein D1(cyclin D1),cyclin dependent kinase 2(CDK2),B-lymphoblastoma-2(Bcl-2),Bcl-2 associated X protein(BAX)proteins in cells of each group.Results:Compared with those in the PHN-0 group,the proliferation activity,the number of clone formation,the numbers of invasion and migration,IL-8 secretion levels,the positive rate and protein expression of N-cadherin,and the expressions of TLR4,NF-κB,HMGB1,RAGE,cyclin D1 and CDK2 protein in the PHN-50,PHN-100,and PHN-200 groups decreased significantly(all P<0.05);and the apoptosis rate,the positivity rate and protein expression of E-cadherin,and the BAX/Bcl-2 ratio increased significantly(all P<0.05).At the same time,overexpression of HMGB1 could reverse the inhibitory effects of PHN on the proliferation,migration,invasion and EMT of U251 cells,as well as its promoting effect on the apoptosis(all P<0.05).Conclusion:PHN inhibits the proliferation,invasion and EMT progression of glioma U251 cells through the HMGB1/RAGE signaling pathway.

Objective To investigate the regulatory role and mechanism of lobetyolin(LBT,a poly-acetylene glycoside isolated from the roots of Codonopsis pilosula)in the proliferation and apop-tosis of brain glioma cells based on the Akt/GSK-3β/Snail signaling pathway.Methods Human brain glioma cell line U-373MG was randomly divided into normal,SC79(Akt activator),LBT,and LBT+SC79 groups.After corresponding interventions,CCK-8 assay,colony formation assay,and flow cytometry were used to detect the proliferation and apoptosis of the cells.Western blot-ting was employed to measure the protein expression levels of the molecules related to prolifera-tion,apoptosis,and Akt/GSK-3β/Snail signaling pathway.After tumor xenograft nude mouse model of U-373MG cells was established,followed by grouping and interventions as above cell experiments,the tumor weight and volume were measured.Immunohistochemical assay and TUNEL assay were performed to detect the proliferation and apoptosis of tumor cells.Western blotting was applied to detect Akt/GSK-3β/Snail signaling pathway related proteins in the nude mouse groups.Results In the LBT+SC79 group,cell viability,number of formed colonies,pro-tein levels of cyclin D1,Bcl-2 and Snail,p-Akt/Akt and p-GSK-3β/GSK-3β,tumor weight and vol-ume,and positive ratios of Ki67,cyclin D1 and Bcl-2 in transplanted tumors were increased(P＜0.05),and cell apoptotic rate[(3.20±1.14)％vs(46.15±1.52)％,P＜0.05],Bax protein level(0.51±0.07 vs 0.89±0.06,P＜0.05),and positive ratios of TUNEL[(51.56±7.13)％vs(74.95±8.61)％,P＜0.05]and Bax[(32.71±5.43)％vs(41.86±4.90),P＜0.05]in transplanted tumors were declined when compared with the LBT group.Conclusion LBT can induce apoptosis and inhibit proliferation of brain glioma cells in vitro and in vivo by blocking activation of the Akt/GSK-3β/Snail signaling pathway.

Objective:To analyze the clinicopathological characteristics of atypical teratoid/rhabdoid tumors (AT/RT) and the causes of pathological misdiagnosis, and summarize diagnostic strategies.Methods:A case series study was conducted.Specifically, the data of 5 misdiagnosed(misdiagnosed group) and 8 confirmed AT/RT cases(confirmed group) in the Department of Pathology of Xi′an Children′s Hospital from January 2010 to December 2018 were retrospectively analyzed.Hematoxylin-eosin and immunohistochemical staining were performed to analyze clinical features, morphology, and immune phenotypes.Rates were compared between the misdiagnosed and confirmed groups by a Fisher′s exact test.Means were compared using an independent sample t-test.Medians were compared by a Mann-Whitney U test. Results:(1)There were 4 males and 1 female in the misdiagnosed group, with a median age of 24 months.In this group, 4/5 tumors were located in the posterior cranial fossa, and 1/5 tumors were located in the spinal cord.Morphologically, rhabdoid cells were detected in 3/5 cases, and the other 2/5 cases consisted of small embryonal cells.Immunohistochemically, INI1 and BRG1 expressions were absent in 4/5 and 1/5 cases, respectively.All of them showed multiple immunephenotypes.There were 7 males and 1 female in the confirmed group, with a median age of 22 months.In the confirmed group, 4/8 tumors were located in the supratentorial region and 4/8 tumors were located in the infratentorial region.Rhabdoid cells, deficient INI1 expression and multiple immunephenotypes were observed in all 8 cases.(2)The percentage of rhabdoid cells in the misdiagnosed group was significantly lower[0.45(0, 0.46)] than that in the confirmed group[0.55(0.40, 0.85)]( Z=-2.064, P=0.039). Conclusions:The causes of misdiagnosis of AT/RT are variable sites of occurrence, diverse histomorphology, multiple phenotypes in immunohistochemistry and rare BRG1 deficiency.For high-grade rhabdoid, epithelioid, and/or embryonic small cell tumors, AT/RT should be differentiated and immunohistochemistry protocols should include INI1 and BRG1.

Objective To observe the value of changes of neutrophil-to-lymphocyte ratio(NLR)before and after the first interventional treatment of hepatocellular carcinoma(HCC)for predicting patient's overall survival(OS).Methods Totally 92 HCC patients who underwent the first time TACE or TACE+hepatic artery infusion chemotherapy(HAIC)were retrospectively enrolled.The patients were divided into NLR ratio(NLRR)＜1.29 group(n=54)and≥1.29 group(n=38)based on the ratio of NLR after to before treatment,also ΔNLR＜0.87 group(n=60)and≥0.87 group(n=32)based on the difference of NLR after and before treatment.Clinical data were compared between groups,survival analysis was performed,and the value of NLRR and ΔNLR for predicting OS were analyzed.Results No significant difference of clinical data was found between NLRR＜1.29 and≥1.29 groups,nor between ΔNLR＜0.87 and≥0.87 groups(all P＞0.05).The median OS of 92 patients was 30.90 months,which in NLRR＜1.29 group(55.10 months)was longer than that in NLRR≥1.29 group(22.30 months,P=0.005),while in ΔNLR＜0.87 group(55.10 months)was longer than that in ΔNLR≥0.87 group(14.20 months,P=0.003).Cox regression analysis showed that the maximum diameter of tumor≥5 cm,distant metastasis,ascites,NLRR≥1.29 and ΔNLR≥0.87 were all independent risk factors of OS(all P＜0.05).Taken 1.29 and 0.87 as the best cut-off value,respectively,the area under the curve of NLRR and ΔNLR for predicting OS was 0.620 and 0.610,respectively.Conclusion NLRR and ΔNLR were helpful for predicting OS of HCC patient after the first interventional treatment.

Objective To compare the efficacy and safety of flexible ureteral lithotripsy(FURL)and non-retrograde percutaneous nephrolithotomy(NR-PCNL)for treating1.5-2.0 cm upper ureteral stones.Methods We retrospectively analyzed clinical data of 130 patients with upper ureteral stones treated between October 2022 and October 2024.Sixty-two patients underwent FURL and 68 underwent NR-PCNL.Comparisons included operative time,pre-and postoperative changes in white blood cells(WBC),hemoglobin(Hb),and creatinine(Cr),postoperative C-reactive protein(CRP)levels,stone-free rate after primary surgery,postoperative hospitalization duration,pain scores,complications,and need for auxiliary treatments.Results Compared to the FURL group,the NR-PCNL group demonstrated advantages in operative time[54.0(44.3,69.3)min vs.82.5(66.0,101.0)min,Z=-5.565,P<0.001],WBC elevation[1.9(0.5,3.5)×109/L vs.4.5(3.0,6.0)×109/L,Z=-4.528,P<0.001],and secondary surgery rate[0%(0/68)vs.14.5%(9/62),P<0.001].The FURL group showed lower Hb reduction[3.0(2.0,6.3)g/L vs.8.0(5.0,11.0)g/L,Z=-4.262,P<0.001],less postoperative Visual Analogue Scale(VAS)pain scores[1.0(1.0,2.0)points vs.2.0(1.0,2.0)points,Z=-2.840,P=0.005],and shorter hospitalization duration[2.0(1.0,2.0)d vs.3.0(2.0,3.0)d,Z=-5.815,P<0.001].No significant differences were observed in Cr elevation,CRP levels,stone-free rate after primary surgery,complications,or analgesic requirements(P≥0.05).Conclusions Both NR-PCNL and FURL are safe and effective for 1.5-2.0 cm upper ureteral stones.FURL offers better patient comfort,while NR-PCNL shows superior overall safety.
