Objective To assess the current status and outcomes of living donor liver transplantation (LDLT) in patients with unresectable colorectal cancer liver metastases (CRLM). Methods Two reviewers independently conducted a systematic search of Medline (via PubMed), the Cochrane Library, and ClinicalTrials.gov in accordance with preferred reporting items for systematic reviews guidelines. English-language publications reporting LDLT for unresectable CRLM were identified; study characteristics and recipient outcomes were extracted. Results Twelve studies were retrieved, six completed studies enrolling 55 patients and six ongoing trials. Selected patients appeared to derive benefit from LDLT. Reported overall survival was 100% at 1 year and 100%, 71.4% at 3 years. The 1-year progression-free survival was 85.7% and 75.1%, and 3-year progression-free survival was 68.6% and 53.7%. Conclusions Prospective data on LDLT for unresectable CRLM remain scarce. The approach is still investigational and warrants validation through prospective clinical trials.

ObjectiveTo investigate the therapeutic effect of sitravatinib on carbon tetrachloride （CCl₄）-induced liver fibrosis in mice. MethodsA total of 30 male C57BL/6J mice， aged 8 weeks， were randomly divided into control group， CCl₄ model group， and low- （5 mg/kg）， middle- （10 mg/kg）， and high-dose （20 mg/kg） sitravatinib groups. All mice except those in the control group were given intraperitoneal injection of CCl₄ for 4 consecutive weeks to induce liver fibrosis， and since the first day of modeling， the mice in the low-， middle-， and high-dose sitravatinib groups were given sitravatinib at the corresponding dose by gavage every day. The serum levels of total cholesterol （TC）， triglyceride （TG）， and alanine aminotransferase （ALT） were measured for the mice in each group； hepatic hydroxyproline content was measured； HE staining， Masson staining， and Sirius Red staining were used to observe liver histopathological changes； quantitative real-time PCR and Western blot were used to measure the mRNA and protein expression levels of α-smooth muscle actin （α-SMA） and collagen type I alpha 1 （Col1a1） in liver tissue. The therapeutic effect of sitravatinib was assessed based on the above results. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the control group， the model group had significant increases in the levels of TC， TG， and ALT （all P<0.05）， and there were no significant differences in the levels of TC， TG， and ALT between the model group and the low-， middle-， and high-dose sitravatinib groups （all P>0.05）. Hepatic hydroxyproline content decreased after sitravatinib intervention， with a significant difference between the middle-/high-dose sitravatinib groups and the CCl₄ model group （both P<0.05）. Histopathological staining showed that the sitravatinib treatment groups had a reduction in collagen deposition， along with thinning and fragmentation of fibrous septa， and in the high-dose sitravatinib group， 4 mice had a fibrosis stage of S0—S1 and 2 mice had a fibrosis stage of S2—S3， suggesting a certain degree of alleviation of liver fibrosis degree compared with the CCl₄ model group （mainly S3—S4）. The measurement of related molecules showed that sitravatinib downregulated the mRNA and protein expression levels of α-SMA and Col1a1 （all P<0.05）. ConclusionSitravatinib can effectively alleviate CCl₄-induced liver fibrosis in mice， possibly by inhibiting hepatic stellate cell activation and collagen synthesis.

OBJECTIVE To investigate a dynamic monitoring of drug consumption （DMDC） model based on the seasonal Mann-Kendall trend test， aiming to provide scientific evidence for the efficient and macroscopic monitoring of drug use. METHODS A monitoring list of key outpatient drugs was established based on the top 20% of drugs ranked by sales volume in the outpatient pharmacy in October 2024. A DMDC model based on the Mann-Kendall trend test was constructed using the monthly usage data of key outpatient drugs from November 2021 to October 2024， aiming to eliminate the impact of seasonal fluctuations and analyze the temporal trends in drug consumption. Taking mucolytic expectorants， triazole derivatives for dermatophytosis， and single-agent hydroxymethylglutaryl coenzyme A （HMG-CoA） reductase inhibitors as examples， the monitoring effectiveness of the DMDC model was demonstrated， and its performance was compared with that achieved by the traditional sequential growth rate ranking method. RESULTS A total of 215 drug varieties were included in the monitoring list， and DMDC models were successfully established for all of them. Among these， 119 showed a significant increasing trend （P＜0.05， S′＞0）. The model successfully monitored the monthly consumption of mucolytic expectorants， triazole derivatives for dermatophytosis， and single- agent HMG-CoA reductase inhibitors. The precision and recall rates of the DMDC model for identifying abnormal drug use were 60.7% and 85.0%， respectively， both significantly higher than those of the sequential growth rate ranking method （8.3% and 15.0%， respectively） （χ2＝20.114， P＜0.001； χ2＝19.600， P＜0.001）. CONCLUSIONS DMDC model based on the seasonal Mann-Kendall trend test can effectively identify long-term trends in drug consumption， eliminate seasonal interference， enhance monitoring accuracy and management efficiency， and is suitable for the dynamic monitoring of drug consumption.

ObjectiveTo investigate the potential mechanism of Huatan Sanjie Formula （化痰散结方， HSF） in the treatment of triple negative breast cancer （TNBC） based on the integrinβ1/focal adhesion kinase/yes-associated protein （integrinβ1/FAK/YAP） mechanotransduction signaling pathway. MethodsFifty BALB/c mice were randomly assigned to a model group， doxorubicin group， low-， medium-， and high-dose HSF groups， with 10 mice per group. An orthotopic TNBC transplantation model was established in all mice using syngeneic implantation of 4T1 cells. After successful modeling， mice in the model group received intragastric administration of normal saline 0.2 ml each day. Mice in the low-， medium-， and high-dose HSF groups received HSF by gavage at doses of 5.99， 11.97， and 23.94 g/（kg·d）， respectively. The doxorubicin group received intraperitoneal injections of doxorubicin （1.5 mg/kg） once every two days. All treatments lasted for 30 days. After the final administration， mice were sacrificed， and tumor weight and volume were measured. Hematoxylin-eosin （HE）， Masson's trichrome， and Sirius Red staining were performed to evaluate histopathological changes and collagen fiber deposition in tumor tissues. TUNEL staining was used to assess apoptosis. The Young's modulus of tumor tissues was measured using atomic force microscopy （AFM）. The nuclear-cytoplasmic localization of YAP was determined by immunofluorescence staining. Protein expression levels of integrinβ1， focal adhesion kinase （FAK）， YAP， and phosphorylated focal adhesion kinase （p-FAK） were detected by Western Blotting. The mRNA expression levels of integrinβ1， FAK， and YAP were assessed by quantitative real-time polymerase chain reaction （qRT-PCR）. Pearson correlation analysis was performed to evaluate the relationships among tumor tissue Young's modulus， apoptosis rate， and the expression levels of proteins related to the integrinβ1/FAK/YAP signaling pathway. ResultsCompared to the model group， tumor weight was significantly reduced in the doxorubicin group and the medium- and high-dose HSF groups， while tumor volume significantly decreased in the doxorubicin group and the high-dose HSF group （P＜0.01）. Tumor weight in the high-dose HSF group was significantly lower than that in the low-dose group， and tumor volume was significantly smaller than that in both the low- and medium-dose groups （P＜0.05）. Marked improvements in histopathological morphology were observed in the medium- and high-dose HSF groups and the doxorubicin group， while the proportion of collagen fiber deposition and the nuclear-to-cytoplasmic ratio of YAP were significantly reduced （P＜0.01）. Compared to the model group， all three HSF groups and the doxorubicin group exhibited significantly increased apoptosis rates， decreased Young's modulus， and reduced mRNA expression levels of integrinβ1， and YAP （P＜0.05 or P＜0.01）. Furthermore， protein expression levels of integrinβ1， p-FAK， and YAP in the high-dose HSF group were significantly lower than those in the model group （P＜0.05 or P＜0.01）. Pearson correlation analysis demonstrated a significant negative correlation between tumor tissue Young's modulus and apoptosis rate （r =-0.93， P＜0.01）. In contrast， the protein expression levels of integrinβ1， p-FAK， and YAP were positively correlated with Young's modulus （r=0.88， 0.97， and 0.98， respectively； P＜0.05） and negatively correlated with apoptosis rate （r=-0.93，-0.97， and -0.93， respectively； P＜0.05）. ConclusionHSF can significantly inhibit tumor growth in TNBC model mice. Its antitumor effect may be associated with reducing tumor tissue stiffness through suppression of the integrinβ1/FAK/YAP mechanotransduction signaling pathway.

ObjectiveTo explore the mechanism of action of Cuscutae Semen-Salviae Miltiorrhizae Radix et Rhizoma in the treatment of recurrent spontaneous abortion （RSA） through network pharmacology， molecular docking， and cell experiment verification. MethodsThe Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and UniPort databases were used to screen and organize the active ingredients and corresponding targets of Cuscutae Semen-Salviae Miltiorrhizae Radix et Rhizoma. The potential therapeutic targets of RSA were screened in Online Mendelian Inheritance in Man （OMIM）， GeneCards database， DrugBank database， DisGeNET database， and Therapeutic Target Database （TTD）. The potential core targets of Cuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma for treating RSA were further screened by constructing a protein-protein interaction （PPI） network and topological analysis. Meanwhile， the Database for Annotation， Visualization and Integrated Discovery （DAVID） was chosen to perform enrichment analysis on intersection targets. On this basis， AutoDock software was used for molecular docking， and the data were imported into PyMOL software for visualization and composition. Finally， the cell counting kit-8 （CCK-8） experiment， Transwell cell invasion assay， and Western blot were used to detect the effects of serum containing Cuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma on HTR-8/SVneo cells and observe the effects on the interleukin （IL）-6/signal transducer and activator of transcription 3（STAT3） signaling pathway and related proteins. ResultsThrough network pharmacology analysis， a total of 69 active ingredients， 73 potential therapeutic targets， and 17 core targets， including IL-6， IL-10， and STAT3， were collected. The 73 common targets were enriched in 614 Gene Ontology （GO） entries and 57 Kyoto Encyclopedia of Genes and Genomes （KEGG） signaling pathways. The molecular docking results indicated that IL-6 and STAT3 had good binding ability with the main active ingredients， including matrine， cryptotanshinone， and tanshinone Ⅱ_A. The cell experiment results showed that， compared with those of the control group， after 24 hours of treatment with the drug-containing serum， the survival and invasion rates of HTR-8/SVneo cells were significantly increased （P<0.05）， and the expression of IL-6/STAT3 signaling pathway and related proteins IL-10 and c-Myc was significantly elevated （P<0.05）. Moreover， the trend of action in the drug-containing serum group was consistent with that of pathway agonists. ConclusionCuscutae Semen-Salviae miltiorrhizae Radix et Rhizoma may enhance the survival rate and invasive activity of HTR-8/SVneo cells to further prevent and treat RSA by activating the IL-6/STAT3 signaling pathway and upregulating the expression of downstream factors IL-10 and c-Myc in the pathway.

Background China is a major coal producer and consumer country in the world. Coal workers' pneumoconiosis (CWP) is a primary factor endangering the occupational health of coal miners. Research on the disease burden of CWP and its changing trend is significant for disease prevention & control and associated policies. Objective To analyze the disease burden of CWP in China from 1990 to 2021 and its changing trend, and predict the disease burden from 2022 to 2035. Methods Using the Global Burden of Disease Study (GBD) database of 2021, numbers ofincident cases, prevalent cases, deaths, and disability-adjusted life years (DALYs) as well as crude and age-standardized rates of CWP in China were retrieved. Linear regression model was used to calculate the estimated annual percentage change (EAPC) of the age-standardized rates. Joinpoint regression model was used to analyze the temporal trend of disease burden and the disease burden of different sexes and age groups, and Bayesian age-period-cohort (BAPC) model was used to forecast the trend of CWP disease burden. Results In 1990, the incident, prevalent, and deaths cases of CWP in China were 3266, 18872, and 1561, respectively, and the DALYs of CWP were 44614.718 person-years. In 2021, the incident, prevalent, and deaths cases of CWP were 3446, 23975, and 1229, respectively, and the DALYs of CWP were 29610.754 person-years. From 1990 to 2021, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP in China all showed a downward trend, with the EAPCs of −3.121%, −2.532%, −4.018%, and −4.268%, respectively. The disease burden of CWP in China was mainly concentrated in the male population. The annual average percent change analysis indicated that each standardized rate showed a fluctuating downward trend in different periods. The BAPC model showed that from 2022 to 2035, the age-standardized rates of CWP in China would continue to decline steadily. In 2035, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP would be reduced to 0.10 per 100000, 0.74 per 100000, 0.03 per 100000, and 0.74 per 100000, respectively. Conclusion The disease burden contributed by CWP in China generally show a downward trend from 1990 to 2021, and it is expected that the age-standardized rates will continue to decline steadily from 2022 to 2035.

Objective: To explore the dynamic relationship between depressive symptom and non-suicidal self-injury(NSSI) behavior among rural left behind junior high school students, as well as the mediating role of social support, so as to provide a reference for preventing the occurrence of behaviors that endanger the physical and mental health of rural adolescents. Methods: In October 2023, 828 rural left behind junior high school students from four counties and cities in Xiangxi Autonomous Prefecture, namely Luxi County, Huayuan County, Baojing County and Longshan County, were selected by cluster random sampling for a one year follow up investigation (T1:October 2023,T2:April 2024,T3:October 2024). Depressive symptom, NSSI behavior and social support of junior high school students were evaluated by using the Patient Health Questionnaire-9(PHQ-9),Adolescent Non suicidal Self injury Assessment Questionnaire (ANSAQ), and Social Support Scale for University Students(SSSUS). A cross lag panel model was constructed to analyze the dynamic relationship between depression symptom and NSSI behavior, as well as the longitudinal mediating role of social support. Results: The levels of depressive symptoms(T1-T3:150.00±5.88，14.29±7.52，13.97±6.70) and NSSI behavior (T1-T3:6.91±4.65，6.10±3.92，4.79±3.51) of rural left behind junior high school students both showed downward trends ( F =13.41, η 2=0.02; F =50.49, η 2=0.06), the level of social support (59.17±14.68，62.27±15.36，61.82±15.90) showed an upward trend ( F =20.94, η 2=0.03), and the depressive symptom and NSSI behavior of girls were higher than those of boys ( F =19.91, η 2=0.02; F =4.57, η 2=0.01)(all P <0.05). The positive predictive relationships between depressive symptom and NSSI behavior among rural left behind junior high school students [depressive symptom of T1 positively predicted NSSI behavior of T2 and T3 ( β =0.10, 0.16); depressive symptom of T2 positively predicted NSSI behavior of T3 ( β =0.14), all P <0.01]. Social support during the T2 period played a partial mediating role between depressive symptom in T1 and NSSI in T3, with a mediating effect of 0.02 (95% CI =0.01-0.17, P <0.05). Conclusions Depressive symptom positively predict the occurrence of NSSI behavior among rural left behind junior high school students. Social support is an important mediating factor in alleviating the influence of depressive symptoms on the occurrence of NSSI behavior. It should prevent and reduce the occurrence of depression symptoms and NSSI behavior by improving the social support level of rural left behind junior high school students.
