Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

Objective:To explore the therapeutic law of moxibustion in Professor Zhou Meisheng's medical manuscripts for epidemic hemorrhagic fever (EHF) based on data mining and knowledge map technology.Methods:The manuscript data of Professor Zhou Meisheng's moxibustion treatment of EHFwere collected from Infectious Diseases Department of Dangshan County People's Hospital from December 16, 1985 to December 25, 1987. Graphpad Grism 8.0 software was used for descriptive analysis. PHP 5.4 program code was used for association rule analysis. SPSS Statistics 26.0 was used for clustering analysis. Neo4j Community 3.5.25 database was used to analyze the syndrome-weight graph.Results:205 prescriptions were included. There were 21 symptoms with frequency>40, in which the frequency of aversion to cold, fever, rash and irritability was 100%. The main types of moxibustion methods used in the treatment included moxibustion frame fumigation moxibustion, Wanying acupoint moxibustion pen moxibustion, and fire needle instead of moxibustion. There were 29 acupoints with a frequency of >25, including Zhongwan (CV12), Shenshu (BL23) and Mingmen (DU4), etc. Association rules showed that Sanyinjiao (SP6)-Zhongwan (CV12)-Feishu (BL13)-Shenshu (BL23)-Zhiyang (DU9) had the highest correlation. Six effective clustering combinations of moxibustion for EHF were summarized by clustering analysis. The weight graph can obtained the first 30 relationships with high correlation of target syndromes.Conclusions:Professor Zhou applied the idea of "moxibustion for heat syndrome" to the treatment of EHF, and took the method of "acupoint selection according to symptoms" as the main acupoint selection idea for moxibustion treatment of EHF. In clinical practice, moxibustion combined with auxiliary operation of TCM is often used to treat EHF, which can achieve good results.

Objective: To explore the factors affecting the prevalence of HIV-associated neurocognitive disorders (HAND) among HIV/AIDS patients, so as to provide insights into developing HAND prevention measures. Methods: HIV/AIDS patients aged 18 years and above in the Infection Department of Nanjing Second Hospital were selected.Demographic data, treatment regimen and blood biochemical indicators were collected. Depression was evaluated using Patient Health Questionnaire Depression Scale, frailty was evaluated using Chinese version of Tilburg Frailty Indicator, and HAND was evaluated by Montreal Cognitive Assessment Scale. Factors affecting HAND were analyzed using a multivariable logistic regression model. Results: Totally 440 questionnaires were allocated and 426 valid questionnaires were recovered, with an effective rate of 96.82%. The median age of patients investigated was 33.00 (interquartile range, 10.00) year. There were 407 males, accounting for 95.54%; 232 patients with bachelor degree or above, accounting for 54.46%; 171 patients with HAND, accounting for 40.14%. Multivariable logistic regression analysis showed that educational level (bachelor degree or above, OR=0.291, 95%CI: 0.157-0.541), depression (OR=2.499, 95%CI: 1.530-4.083), frailty (OR=2.121, 95%CI: 1.307-3.441) and treatment regimen including efavirenz (OR=2.223, 95%CI: 1.367-3.615) were the influencing factors for HAND among HIV/AIDS patients. Conclusion Educational level, depression, frailty and use of efavirenz may be associated with HAND risk.

Genome-wide association studies have identified many AD risk genes related to immune response and microglia. This paper mainly reviews immune-related AD risk genes, describing their biological functions and possible roles in AD, in order to provide new scientific basis for early prevention and treatment of AD.

Objectives:To discuss the inhibitory effect of Lactobacillus reuteri on the replication of rotavirus(RV)strain SA11 in vivo and in vitro,and to clarify its effect on the expression of related immune factors.Methods:For in vitro experiments,Lactobacillus reuteri was cultured and identified,and the standard curve and growth curve were plotted to screen the optimal time and concentration for Lactobacillus reuteri cultivation.The cells were infected with Lactobacillus reuteri at the concentrations of 5×108,10×108,50×108,100×108,200×108,and 500×108 CFU·mL-1,and the surival rates of Caco-2 cells were detected by trypan blue staining method.Various concentrations of Lactobacillus reuteri were co-incubated with RV in vitro and applied to the Caco-2 cells.The cells were divided into negative control group(NC group),positive control group(PC group),and 107,108,109,and 1010 CFU·mL-1 Lactobacillus reuteri groups.Immunofluorescence focus method was used to detect the viral titers in the Caco-2 cells after treated with Lactobacillus reuteri and real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the copy numbers of RV VP6 gene in the Caco-2 cells after treated with various concentrations of Lactobacillus reuteri.In in vivo experiments,25 litters of SPF suckling mice were divided into control group,RV group(infected with SA11 strain),Ab-NC group(treated with antibiotic to deplete gut microbiota),Ab-RV group(depleting gut microbiota and then infected with SA11 strain),and Ab-Lac-RV group(depleting gut microbiota,treated with Lactobacillus reuteri,and then infected with SA11 strain).The fecal samples were collected on days 2,4,6,8,and 10 gavage,colon tissue sample were collected on day 4 of and RT-qPCR method was used to detect the copy numbers of RV VP6 gene in feces and the mRNA expression levels of interleukin(IL)-1β,IL-8,IL-10,interferon-γ(IFN-γ),and tumor necrosis factor-α(TNF-α)in colon tissue of the suckling mice in vartious groups.Results:The Lactobacillus reuteri grew well,with round,smooth,and milky white convex colonies and neat edges.After Gram staining,the bacteria appeared purple,irregular,and square-shaped rods.16SrDNA sequencing showed 99%sequence homology,indicating successful activation of Lactobacillus reuteri.The number of live Lactobacillus reuteri was linearly related to the absorbance(A)value,and the standard curve for regression analysis was Y=0.437 5X+0.000 6,R2=0.999 4.During the 0-2 h cultivation period,the bacteria were at the logarithmic growth phase with slow growth;from 2-14 h,the bacteria grew rapidly and stabilized at 14-16 h,reaching the growth rate peak at 16 h,after which they entered the decline phase.Infection with Lactobacillus reuteri at concentrations of 5×108,10×108,50×108,100×108,and 200×108 CFU·mL-1 resulted in the survival rates of Caco-2 cells were all>90%,so these concentrations were selected for the further experiments.Compared with PC group,the copy numbers of RV VP6 gene in the Caco-2 cells in 5×108,10×108,50×108,100×108,and 200×108 CFU·mL-1 Lactobacillus reuteri groups were significantly decreased(P<0.01).Compared with PC group,the viral titers in the Caco-2 cells in 107,108,109,and 1010 CFU·mL-1 Lactobacillus reuteri groups were significantly decreased(P<0.01).Compared with control group,the numbers of gut microbiota colonies in Ab-NC,Ab-RV,and Ab-Lac-RV groups were significantly decreased,indicating successful depletion of gut microbiota in the suckling mice.On days 2 and 4 after gavage,the RV VP6 gene copy number in the feces in Ab-RV group was significantly lower than that in RV group(P<0.05).On days 4,6,8,and 10 after gavage,the RV VP6 gene copy number in the feces in Ab-Lac-RV group was significantly lower than that in Ab-RV group(P<0.05).Compared with control group,the expression levels of IL-1β,IL-10,IFN-γ,and TNF-α mRNA in colon tissue in Ab-RV and Ab-Lac-RV groups were significantly increased(P<0.05 or P<0.01),while the expression level of IL-8 mRNA was significantly decreased(P<0.05),and the expression level of IL-10 mRNA in colon tissue in Ab-LAC-RV group was significantly increased(P<0.01).Conclusion:Lactobacillus reuteri may inhibit the RV replication by upregulating the expressions of IL-1β,IL-10,IFN-γ,and TNF-α mRNA and downregulating the expression of IL-8 mRNA.

Objective To evaluate the diagnostic value of endoscopic ultrasonography(EUS)in the preoperative staging and ductal dilatation of duodenal papillary carcinoma and analyze the factors influencing its diagnostic accuracy.Methods A cross-sectional trial was conducted on the patients with pathologically-diagnosed duodenal papillary carcinoma and undergoing EUS in the First Affiliated Hospital of Army Medical University from January 2018 to August 2023.The diagnostic value of EUS for the preoperative staging of duodenal papillary carcinoma was evaluated using sensitivity,specificity,positive predictive value,negative predictive value,and accuracy.Univariate and multivariate analyses were performed to determine the factors affecting the diagnostic accuracy of EUS.Results A total of 102 patients with duodenal papillary carcinoma were included,including 59 males and 43 females,at a mean age of 62 years,and all of them underwent EUS before diagnosis.The accuracy of EUS for tumor T-staging was 86.27％,the sensitivity and specificity for T1,T2,T3,and T4 lesions were 84.21％,92.31％,85.00％,60.00％,and 95.31％,88.89％,96.34％,and 98.97％,respectively.The positive predictive value for T-staging of T1,T2,T3,and T4 lesions was 91.43％,83.72％,85.00％,and 75.00％,and the negative predictive values were 91.04％,94.92％,96.34％,and 97.96％,respectively.There were 14 patients whose T-staging was incorrectly staged by EUS.The accuracy of EUS in assessing intraductal dilatation was 75.49％,and the sensitivity,specificity,positive predictive value,and negative predictive value for ductal dilatation were 96.97％,66.67％,98.97％,and 40.00％,respectively.In addition,the independent predictors of diagnostic accuracy of EUS for pancreatic duct dilatation were nerve infiltration,tumor size,and T stage;whereas the independent risk factors for diagnostic accuracy of bile duct dilatation were nerve infiltration and alkaline phosphatase.Conclusion EUS has quite higher diagnostic value for preoperative staging of duodenal papillary carcinoma,and nerve infiltration,tumor size,T stage,T stage and alkaline phosphatase may be the influencing factors for its diagnostic accuracy.

Objective:To understand the awareness and influencing factors of core information on tuberculosis prevention and control in the elderly population in China.Methods:The study included all participants aged ≥60 from the "13 th Five-Year" National Tuberculosis Control Plan end-term assessment in 2020, with 13 706 valid questionnaires obtained. Multivariate logistic regression was used to analyze the influencing factors of the awareness rate of core information on tuberculosis prevention and control in the elderly. Results:The total awareness rate of core information on tuberculosis prevention and control in the elderly aged ≥60 was 78.4%, with the highest for "suspicious symptoms of pulmonary tuberculosis" (85.4%) and the lowest for "whether pulmonary tuberculosis can be cured" (65.3%). The complete awareness rate of core information on tuberculosis prevention and control in the elderly was 41.3%, and the proportion of those who received tuberculosis health education is 67.6%. Multivariate logistic regression analysis results showed that factors associated with low awareness of core information included females ( OR=0.93, 95% CI: 0.86-1.00), ages 70- ( OR=0.91, 95% CI: 0.84-0.98) and ≥80 ( OR=0.77, 95% CI: 0.68-0.87) and minority ethnicity ( OR=0.85, 95% CI: 0.74-0.99). Factors associated with high awareness of core information included educational levels of junior high school ( OR=1.46, 95% CI: 1.34-1.58), high school ( OR=1.62, 95% CI: 1.45-1.81), junior college ( OR=1.37, 95% CI: 1.11-1.68), and an undergraduate degree or higher ( OR=1.52, 95% CI: 1.09-2.11), and receiving tuberculosis health education ( OR=2.13, 95% CI: 1.97-2.27). Conclusions:In 2020, the awareness rate of core information on tuberculosis prevention and control in Chinese older adults aged ≥60 was lower than the national planning target. Therefore, there should be an increased focus on health education about tuberculosis for elderly females, those aged ≥70, ethnic minorities, and those with lower education levels.

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the efficacy of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects who were previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extended or switched TMF treatment for 48 weeks. Efficacy was evaluated based on virological, serological, biological parameters, and fibrosis staging. Statistical analysis was performed using the McNemar test, t-test, or Log-Rank test according to the data. Results:593 subjects from the initial TMF group and 287 subjects from the TDF group were included at week 144, with the proportions of HBV DNA<20 IU/ml at week 144 being 86.2% and 83.3%, respectively, and 78.1% and 73.8% in patients with baseline HBV DNA levels ≥8 log10 IU/ml. Resistance to tenofovir was not detected in both groups. For HBeAg loss and seroconversion rates, both groups showed a further increase from week 96 to 144 and the 3-year cumulative rates of HBeAg loss were about 35% in each group. However, HBsAg levels were less affected during 96 to 144 weeks. For patients switched from TDF to TMF, a substantial further increase in the alanine aminotransferase (ALT) normalization rate was observed (11.4%), along with improved FIB-4 scores.Conclusion:After 144 weeks of TMF treatment, CHB patients achieved high rates of virological, serological, and biochemical responses, as well as improved liver fibrosis outcomes. Also, switching to TMF resulted in significant benefits in ALT normalization rates (NCT03903796).

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the safety profile of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects that previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extending or switching TMF treatment for 48 weeks. Safety profiles of kidney, bone, metabolism, body weight, and others were evaluated.Results:666 subjects from the initial TMF group and 336 subjects from TDF group with at least one dose of assigned treatment were included at week 144. The overall safety profile was favorable in each group and generally similar between extended or switched TMF treatments from week 96 to 144. In subjects switching from TDF to TMF, the non-indexed estimated glomerular filtration rate (by non-indexed CKD-EPI formula) and creatinine clearance (by Cockcroft-Gault formula) were both increased, which were (2.31±8.33) ml/min and (4.24±13.94) ml/min, respectively. These changes were also higher than those in subjects with extending TMF treatment [(0.91±8.06) ml/min and (1.30±13.94) ml/min]. Meanwhile, switching to TMF also led to an increase of the bone mineral density (BMD) by 0.75% in hip and 1.41% in spine. On the other side, a slight change in TC/HDL ratio by 0.16 (IQR: 0.00, 0.43) and an increase in body mass index (BMI) by (0.54±0.98) kg/m 2 were oberved with patients switched to TMF, which were significantly higher than that in TMF group. Conclusion:CHB patients receiving 144 weeks of TMF treatment showed favorable safety profile. After switching to TMF, the bone and renal safety was significantly improved in TDF group, though experienceing change in metabolic parameters and weight gain (NCT03903796).
