Hepatitis B virus （HBV） infection is the primary cause of viral hepatitis and represents a substantial disease burden in China. However， effective and safe agents capable of completely eliminating HBV DNA are still lacking. In modern medicine， anti-HBV strategies mainly target covalently closed circular DNA （cccDNA）， among other mechanisms， and multiple novel drugs are currently under clinical investigation. Traditional medicine has been shown to exert anti-HBV effects through direct pathways， such as blocking viral entry， as well as indirect pathways， including the regulation of programmed cell death. Studies have confirmed that the integration of traditional Chinese medicine （TCM） and Western medicine in treating HBV infection and its related complications offers complementary advantages， particularly in enhancing HBV clearance rates， improving liver function， preventing various complications， and delaying the progression from hepatic fibrosis to hepatocellular carcinoma. This review focuses on advances in anti-HBV research involving TCM， Western medicine， and their integrated application， aiming to provide a basis for integrated HBV therapy and new drug development.

Objective:To investigate the effects of enolase 1(ENO1)on the proliferation,migration,and invasion of gastric cancer cells and its underlying molecular mechanisms.Methods:The expression levels of ENO1 in human gastric cancer cell lines(HGC27,MKN-45,N-87,MGC803,BGC-823)and human gastric mucosal epithelial cells(GES-1)were detected using WB assay.Gene editing tools such as CRISPR and overexpression system were used to construct ENO1 knockdown and knockdown-rescue cell lines.Both MKN-45 and BGC-823 cells were grouped into control(Ctrl)group,ENO1 knockdown(ENO1 KD)group,and ENO1 knockdown-rescue(ENO1 KD-OE)group.The effects of ENO1 knockdown or ENO1 knockdown-rescue on the proliferation,migration,invasion,and apoptosis of gastric cancer cells were evaluated using colony formation assay,EdU staining,scratch wound healing assay,Transwell chamber assay and flow cytometry.Additionally,a xenograft model was established in nude mice,and the effects of ENO1 on tumor growth were monitored using small animal in vivo imaging and tumor tissue block measurement.ENO1 was silenced in MKN-45 cells employing RNA interference technology,and the downstream target genes of ENO1 were identified using RNA co-immunoprecipitation sequencing(RIP-seq)and bioinformatics analysis.The molecular mechanisms by which ENO1 regulates the proliferation,migration and invasion of gastric cancer cells was also analyzed.Results:ENO1 was significantly upregulated in gastric cancer cell lines(P<0.01 or P<0.001).ENO1 knockdown significantly inhibited proliferation,migration,and invasion while promoting apoptosis in MKN-45 and BGC-823 cells(P<0.001,P<0.000 1).Rescue experiments showed that restoring ENO1 expression significantly enhanced cell proliferation,migration,invasion,and inhibited apoptosis(P<0.05,P<0.01,P<0.001,P<0.000 1).In vivo experiments demonstrated that ENO1 knockdown significantly inhibited tumor growth in nude mice(P<0.000 1).The differentially expressed genes interacting with ENO1 protein were primarily enriched in pathways related to RNA splicing.Additionally,ENO1 protein was found to interact with the PKM gene,and their expressions showed a positive correlation in gastric cancer tissues(r=0.886).Conclusion:ENO1 is highly expressed in gastric cancer cells.ENO1 interacts with precursor mRNA of PKM to influence its RNA splicing process,thereby regulating PKM2 expression and promoting gastric cancer progression.

Aim To investigate the protective effect of Siwu decoction(SWD)on immune injury induced by 60Coγ-rays in mice and the related mechanism.Meth-ods C57BL/6J mice were randomly divided into six groups:Control group(Control),Model group(Mod-el),Siwu decoction low-dose group(SWD-L),Siwu decoction medium-dose group(SWD-M),Siwu decoc-tion high-dose group(SWD-H)and resveratrol positive group(Resveratrol,Res).The drug was continued to be administered 11 days before and after irradiation,with a single whole-body irradiation of 4 Gy,and all in-dexes were detected three days after irradiation.The changes of peripheral blood and organ indexes were de-tected.Serum levels of cytokine interferon gamma(IFN-γ),interleukin-1 β(IL-1 β),IL-2,IL-4,IL-6,IL-10,IL-17,transforming growth factor-β(TGF-β),tumor necrosis factor(TNF)-α,and immunoglobulin A(IgA),IgG,IgM,and complement protein 3(C3),C4 content were detected by enzyme-linked immunosorbent assay(ELISA).B lymphocytes,T lymphocytes,NK cells in spleen and T lymphocytes in thymus were de-tected by flow cytometry.The pathological changes of spleen and thymus were analyzed by hematoxylin-eosin(HE)staining.The expression of Sirt 1 protein in spleen after radiation was detected by immunofluores-cence staining.The protein contents of Sirt1,PI3K,Akt,p-Akt and mTOR in spleen were detected by Western blot assay.Results SWD could significantly increase LYMPH％and reduce pathological injury of spleen and thymus.Flow cytometry showed that SWD could significantly increase the percentage of CD19+B lymphocytes in spleen,decrease the percentage of NK lymphocytes and the ratio of CD4+/CD8+in spleen and thymus.ELISA results showed that SWD signifi-cantly inhibited the expression of IL-1 β,IL-2,IL-6,IL-17,IFN-γ,TGF-β,TNF-α,and increased the content of anti-inflammatory factors IL-4 and IL-10.At the same time,SWD significantly inhibited the increase of IgA,IgG,IgM,C3 and C4 induced by radiation.The results of immunofluorescence staining and Western blot showed that SWD could decrease the expression of PI3K,Akt,p-Akt and mTOR protein,and enhance the expression of Sirt1 protein.Conclusions SWD has obvious preventive effect on immune damage induced by 60Co gamma radiation in mice.The mechanism may be related to Sirt1-PI3K-Akt-mTOR.

This research aims to construct a stable epithelial cell senescence model for screening and e-valuation of senolytics.We explored the optimal conditions for doxorubicin-induced senescence of non-transformed epithelial cells MCF 10A,including the optimal induction concentration,the optimal inter-vention time,and the optimal senescence duration,and confirmed the feasibility of MCF 10A as an epi-thelial senescence model by multiple ways.The optimal condition for Doxorubicin-induced senescence of MCF 10A cells was treatment with 0.6 μmol/L Doxorubicin for 16 h to achieve the best senescence state on the 8th day.Under the optimal induction conditions,the positive rate of senescence-associated β-gal-actosidase(SA-β-gal)staining in the treated group reached 97％.At the same time,biochemical results of detecting the expression of mRNA,proteins,and immunofluorescence demonstrated that the expression levels of senescence-associated secretory phenotype(SASP),p16,p21 and p53 in the treated group were significantly higher than those in the control cells,and Lamin B1 was significantly decreased(P＜0.001),which were consistent with the specific characteristics of senescence.In summary,an epithelial senescence model was successfully induced in MCF 10A cells by Doxorubicin in this study,which will promote the screening of senolytics for senescent epithelial cells.

Objective:To explore the trajectory and predictors of depressive symptoms in disabled middle-aged and elderly adults in China.Methods:Survey data from the 2013-2020 China Health and Retirement Longitudinal Study (CHARLS) data of disabled middle-aged and elderly adults were selected to analyze the trajectory categories of depressive symptom in disabled middle-aged and elderly adults and to explore their predictors.Results:A total of 1 844 disabled middle-aged and elderly adults were analyzed for survey data. The trajectory of depressive symptoms in disabled middle-aged and elderly adults was categorized into four groups, including a low-level depression group, a depression remission group, a high-level depression group, and a depression worsening group. Logistic regression analyses revealed that gender, age, place of residence, chronic disease, self-rated health, social participation, cognition, and hearing ability were predictors of trajectories of depressive symptoms in disabled middle-aged and elderly adults.Conclusions:There is group heterogeneity in the trajectory of depressive symptoms among disabled middle-aged and elderly adults. Healthcare professionals can carry out targeted health management according to the characteristics of different categories of people.

Objective To explore the technical process and clinical application of laparoscopic combined upper midline incision minimally invasive liver transplantation. Methods A retrospective analysis was conducted on 30 cases of laparoscopic combined upper midline incision minimally invasive liver transplantation. The cases were divided into cirrhosis group (15 cases) and liver failure group (15 cases) based on the primary disease. The surgical and postoperative conditions of the two groups were compared. Results All patients successfully underwent laparoscopic "clockwise" liver resection, with no cases of passive conversion to open surgery or intolerance to pneumoperitoneum. In 6 cases, the right lobe was relatively large, and the right hepatic ligaments could not be completely mobilized. One case required an additional reverse "L" incision during open surgery. All patients successfully completed the liver transplantation, with no major intraoperative bleeding, cardiovascular events, or other occurrences in the 30 patients. The model for end-stage liver disease (MELD) score in the cirrhosis group was lower than that in the liver failure group (P<0.001). There were no statistically significant differences between the two groups in terms of age, surgical time, blood loss, anhepatic phase, or cold ischemia time (all P>0.05). During the perioperative period, there was 1 case of hepatic artery embolism, 1 case of portal vein anastomotic stenosis, no complications of hepatic vein and inferior vena cava, and 3 cases of biliary anastomotic stenosis, all of which occurred in the liver failure group. Conclusions In strictly selected cases, the minimally invasive liver transplantation technique combining laparoscopic hepatectomy with upper midline incision for graft implantation has the advantages of smaller incisions, less bleeding, relatively easier operation, and faster postoperative recovery, which is worthy of clinical promotion and application.

Objective To explore the feasibility and clinical experience of the middle hepatic vein splitting-reconstruction technique in split liver transplantation from low-age donor livers. Methods A retrospective analysis was conducted on the cases of two low-age donor livers that underwent middle hepatic vein splitting-reconstruction, which were transplanted into four child recipients at the Liver Transplantation Center of the Third Affiliated Hospital of Sun Yat-sen University from January 2017 to July 2023. The surgical and postoperative conditions were summarized and analyzed. Results Donor 1 was a 6-year-old and 4-month-old girl with a body weight of 21 kg, and the obtained donor liver weighed 496 g. After splitting, the left and right liver weights were 201 g and 280 g, and transplanted into a 9-month-old boy weighing 6.5 kg and a 9-month-old boy weighing 7.5 kg, respectively. The graft to recipient weight ratio (GRWR) was 3.09% and 3.73%, respectively. Donor 2 was a 5-year-old and 8-month-old boy with a body weight of 19 kg, and the donor liver weighed 673 g. After splitting, the left and right liver weights were 230 g and 400 g, and transplanted into a 13-month-old girl weighing 9.5 kg and a 15-month-old boy weighing 12 kg. The GRWR was 2.42% and 3.33%, respectively. Both donor livers were split ex vivo, with the middle hepatic vein being completely split in the middle and reconstructed using allogeneic iliac vein and iliac artery vascular patches. According to GRWR, none of the 4 transplant livers were reduced in volume. Among the 4 recipients, one died due to postoperative portal vein thrombosis and non-function of the transplant liver, while the other three cases recovered smoothly without early or late complications. Regular follow-up was conducted until July 31, 2023, and liver function recovered well. Conclusions Under the premise of detailed assessment of the donor liver and meticulous intraoperative operation, as well as matching with suitable child recipients, low-age donor livers may be selected for splitting. The complete splitting and reconstruction of the middle hepatic vein in the middle may effectively ensure the adequate venous return of the left and right liver and provide sufficient functional liver volume.

Efferocytosis refers to the process of phagocytes engulfing and clearing the cells after programmed cell death. In recent years, an increasing number of studies have shown that the mechanisms of efferocytosis are closely related to drug-induced liver injury, hepatic ischemia-reperfusion injury, viral hepatitis, cholestatic liver diseases, metabolic-associated fatty liver disease, alcoholic liver disease, and other liver disorders. This review summarized the research progress on the role of efferocytosis in liver diseases, with the hope of providing new targets for the prevention and treatment of liver diseases.
