ObjectiveTo investigate the imaging features of calcium salt deposition and serological markers in patients with alveolar echinococcosis through a retrospective analysis， as well as independent risk factors for the degree of calcium salt deposition in lesions， and to provide a basis for assessing disease process. MethodsA retrospective analysis was performed for the imaging and clinical data of 107 patients with alveolar echinococcosis who were admitted to The First Affiliated Hospital of Shihezi University from December 2023 to June 2025， and according to the volume of calcium salt deposition， they were divided into non-deposition group with 16 patients， mild deposition group with 52 patients， moderate deposition group with 16 patients， and severe deposition group with 23 patients. A one-way analysis of variance or the Kruskal-Wallis H test was used for comparison of continuous data between groups， and the χ² test or Fisher’s exact test was used for comparison of categorical data between groups. The four groups were further combined into the low deposition group （no/mild deposition） and the high deposition group （moderate/severe deposition）. A binary logistic regression analysis was used to investigate the independent influencing factors for calcium salt deposition， and a predictive model was established. The receiver operating characteristic （ROC） curve was used to assess the predictive performance of the model， and the Bootstrap method was used for internal validation. ResultsThere were significant differences between the four groups in sex distribution， involvement of other sites， white blood cell count， lymphocyte percentage， fibrinogen， uric acid， sodium ion， chloride ion， and calcium ion （all P<0.05）. The univariate analysis showed that there were significant differences between the four groups in sex， involvement of other sites， white blood cell count， lymphocyte percentage， fibrinogen， alanine aminotransferase， albumin， creatinine， uric acid， sodium ion， chloride ion， and calcium ion （all P<0.1）. The multi-collinearity diagnosis showed that the VIF values for all continuous variables ranged from 1.104 to 1.760， suggesting that collinearity did not affect modeling. An ordinal logistic regression model was established based on sex， involvement of other sites， calcium ion， lymphocyte percentage， and uric acid. The multivariate analysis showed that lymphocyte percentage （odds ratio ［OR］=1.106， 95% confidence interval ［CI］： 1.041 — 1.174， P=0.001） and blood calcium level （OR=0.005， 95%CI： 0.000 —0.230， P=0.007） were independent influencing factors for the degree of calcium salt deposition. The regression equation was established as Logit（P）=8.231 + 0.100 × lymphocyte percentage -5.344 × calcium ion. The ROC curve analysis showed that the model had an area under the ROC curve of 0.716， with a Youden index of 0.353， a sensitivity of 1.000， and a specificity of 0.353. The Hosmer-Lemeshow test showed that the model had poor calibration （χ²=20.688， P=0.008）. The Bootstrap method with 1000 repeated samples showed that the estimated values of lymphocyte percentage （OR=1.106， 95%CI： 1.049 — 1.186， P=0.002） and calcium ion （OR=0.005， 95%CI： 0.000 — 0.214， P=0.010） were consistent with the original model， and the confidence intervals did not include 1， which further supported the reliability of the model. ConclusionBoth lymphocyte percentage and blood calcium level are independent influencing factors for calcium salt deposition in alveolar echinococcosis， and the degree of calcium salt deposition in alveolar echinococcosis lesions increases with the reduction in blood calcium level and the increase in lymphocyte percentage.

OBJECTIVE To evaluate the cost-effectiveness of lecanemab for early Alzheimer disease （AD） from a whole-society perspective. METHODS Based on data from the Clarity AD study， a global multicenter， randomized， double-blind， placebo-controlled study of lecanemab for early AD， a Markov model was developed according to the disease progression of AD， with a monthly cycle and a time horizon extending to 99% patient mortality. Quality-adjusted life year （QALY） and incremental cost-effectiveness ratio （ICER） were used as outcome indicators， with a willingness-to-pay （WTP） threshold set at twice China’s per capita gross domestic product （GDP） for 2025 （199 330.00 yuan/QALY）. The model simulated the cost-effectiveness of lecanemab plus standard of care （SoC） versus placebo plus SoC for early AD. One-way sensitivity analysis， probabilistic sensitivity analysis， and scenario analysis were employed to test the robustness of the results. RESULTS Compared with placebo plus SoC， the ICER for lecanemab plus SoC was 4 364 711.54 yuan/QALY. One-way sensitivity analysis showed that the hazard ratio for disease progression， the price of lecanemab， body weight， the monthly progression probability of mild cognitive impairment， and the discount rate were key parameters affecting model robustness. Results of the probabilistic sensitivity analysis showed that the probability of lecanemab being cost-effective was 0 at the current WTP threshold. Scenario analysis indicated that a price reduction of at least 94.88% would be required for lecanemab to fall below the WTP threshold. CONCLUSIONS At the current WTP threshold， lecanemab plus SoC is not cost-effective compared with placebo plus SoC for early AD.

Bovine rotavirus(BRV)is an important pathogen causing diarrhea in calves.To understand the genomic charac-teristics and genetic variations in bovine rotavirus,and to further enrich data on the biological characteristics of rotavirus,we aimed to amplify 11 gene segments of the isolated and cultured G6P[1]bovine rotavirus BLL strain,perform whole genome se-quencing,and analyze the molecular characteristics.MEGA7.0 and DNAMAN software were used for homology and typing a-nalysis,and the whole genome phylogenetic tree was constructed to analyze genetic evolution relationships.The complete geno-type of the BLL strain was G6-P[1]-I2-R2-C2-M2-A3-N2-T6-E2-H3.Phylogenetic analysis of the VP7 and VP4 genes of the BLL strain showed that the VP7 gene had the highest homology with RVA/Cow-wt/HB01/China/2021,and the VP4 gene of the BLL strain was in the same branch as RVA/Human-tc/ISR/Ro8059/1995.From the sequence alignment of VP8*amino acids,the sialic acid domain of the BLL strain was found to be similar to that in other P[1]strains,but different from those in other types of strains,except for residue 189,which was the same as that in Ro8059 but different from that in other strains.The results suggested that the BLL strain might potentially infect humans.Therefore,continued monitoring and study of the biological characteristics of this strain are necessary to provide more information and evidence supporting further research on the cross-species transmission of group A rotavirus in China.

Post-translational modification of protein is a key mechanism for regulating cancer development and immune re-sponses,and has become an important target for cancer diagnosis and treatment.Among them,lactylation modification provides a new perspective for the precise prevention and control of tumors by affecting metabolism and epigenetics.Lactylation modification precisely regulates the functions of histone and non-histone,affecting tumor cell characteristics,microenvironment acidification,and immune cell functions,becoming a key hub connecting metabolic reprogramming and malignant phenotypes.This article reviews the regulatory roles of lactylation modification in tumor development,immune escape,clinical translation,and explores the potential of targeted inhi-bition of lactylation modification and its related pathways,as well as the inhibition of key enzyme activity.

Objective To elucidate the effects and mechanisms of Biejiajian pill(BJJP)-containing serum on the malignant biological behaviors of hepatocellular carcinoma Huh7 cells.Methods This research knocked down CKLF-like MARVEL transmembrane domain containing 6(CMTM6)expression using a CMTM6-specific small interfering RNA(siRNA).Healthy Sprague-Dawley rats were used to prepare normal rat serum and low-(0.55 g/kg),medium-(1.1 g/kg),and high-(2.2 g/kg)BJJP-containing.Huh7 cells were cultured with normal fetal bovine serum(BC),normal rat serum(NC),and low-,medium-,and high-dose BJJP serum(LBJJP,MBJJP,and HBJJP,respectively).BJJP-containing serum and si-CMTM6 were applied to Huh7 cancer cells,and the proliferation,migration,and invasion abilities were evaluated by CCK-8 and Transwell assays,respectively.Protein expression levels of proliferating cell nuclear antigen(PCNA),epithelial-mesenchymal transition(EMT)markers,and CMTM6 were detected by Western blot.Results CMTM6 knockdown significantly reduced the mRNA and protein expression level of CMTM6 in Huh7 cells(P＜0.05).There were no significant differences between the BC and NC groups in terms of cell proliferation,migration,invasion,expression levels of PCNA,EMT markers,and CMTM6(all P＞0.05).BJJP-containing serum markedly inhibited Huh7 cell proliferation,migration,and invasion(P＜0.05),downregulated PCNA,CMTM6,N-cadherin,and Vimentin expression,and upregulated E-cadherin compared with the NC group(all P＜0.05).CMTM6 knockdown suppressed malignant behaviors,with reduced PCNA,Vimentin,and N-cadherin and elevated E-cadherin expression(all P＜0.05).Conclusions BJJP-containing serum can significantly inhibit Huh7 cell growth,invasion,migration,and EMT progression,potentially mediated via CMTM6 suppression.
