Objective:To observe the influence of Jiegu Qili Tablets combined with percutaneous vertebroplasty(PVP)on bone metabolism markers and bone morphogenetic protein-2(BMP-2)and bone morphogenetic protein-7(BMP-7)in patients with osteoporotie vertebral compression fractures(OVCF).Methods:This study was a prospective study,150 patients with OVCF due to qi stagnation and blood stasis syndrome who were admitted to our hospital from April 2022 to April 2024 were divided into control group(received PVP treatment,n=75)and observation group(received Jiegu Qili Tablets on the basis of the control group,n=75)according to the random number table method.Visual analogue scale(VAS),TCM syndrome score and Oswestry dysfunction index(ODI)vertebro-related indicators(anterior compression rate of the injured vertebrae,Cobb's Angle of the injured vertebrae),disappearance time of major symptoms and fracture healing time,bone metabolism markers[bone gla protein(BGP),Beta C-terminal cross-linked telopeptides of type Ⅰ collagen(β-CTX),bone alkaline phosphatase(BALP)]and BMP-2,BMP-71evels before treatment and one month after treatment were compared between the two groups.Results:One month after treatment,the main symptoms,secondary symptoms,total score,VAS,ODI scores,serum β-CTX,BALP levels,anterior compression rate of the injured vertebrae,and Cobb's Angle of the injured vertebrae in the observation group were lower than those in the control group.The disappearance time of the main symptoms and fracture healing time in the observation group were shorter than those in the control group,BGP,BMP-2 and BMP-7 were higher than those in the control group(P＜0.05).Conclusion:Jiegu Qili Tablets combined with PVP in the treatment of patients with OVCF,can effectively promote fracture healing in patients by improving bone metabolism markers and BMP-2 and BMP-7 levels,and is conducive to postoperative recovery of patients.

Objective To describe and analyze the current status,changing trend and influencing factors of the disease burden of cervical,endometrial and ovarian cancer in China from 1990 to 2021.Methods Data on incidence,mortality,disability-adjusted life year(DALY),and other indicators for cervical,endometrial and ovarian cancer were collected from the 2021 Global Burden of Disease database.Joinpoint regression models were used to analyze time trends,and age-period-cohort(APC)models assessed their impact on incidence and mortality.Spearman correlation analysis was performed to evaluate the relationship between the sociodemographic index(SDI)and the cancer indicators.Finally,the attributable risk factors for the disease burden were analyzed.Results From 1990 to 2021,age-standardized incidence rates of cervical and endometrial cancers in China significantly increased,while ovarian cancer showed no significant change.Age-standardized mortality,DALY,and years of life lost due to premature death(YLL)decreased significantly.The disease burden was heavier in middle-aged and older groups.APC model indicated an increase in cervical cancer incidence and a decrease in mortality over time.Furthermore,the incidence risks of cervical and endometrial cancers were elevated in successive birth cohorts,whereas a lower risk was observed for ovarian cancer.Correlation analysis showed significant associations between cancer incidence and mortality with SDI.Obesity has significantly contributed to the disease burden of common gynecologic cancers in China.Conclusion Mortality rates of cervical,endometrial and ovarian cancer have declined,while the incidence of cervical and endometrial cancers has significantly increased.The trends in incidence and mortality are influenced by age,period and cohort effects.Future efforts should focus on controlling risk factors like obesity to reduce the disease burden.

Objective:To investigate the dynamic changes of serum long non-coding ribonucleic acid antisense non-coding RNA in the INK4 locus (LncRNA ANRIL), long non-coding ribonucleic acid maternally expressed gene 3 (LncRNA MEG3) and inflammatory factors [interferon-γ (IFN-γ), interleukin-6 (IL-6), interleukin-18 (IL-18) and interleukin-1β (IL-1β)] in patients with acute ischemic stroke and their correlation with neurological impairment.Methods:This prospective study included fifty-two patients with acute ischemic stroke admitted to the Central Hospital of Dalian University of Technology were included, and the neurological impairments of the patients were scored using the National Institutes of Health stroke scale (NIHSS) on the first day of the onset of the disease, and serum LncRNA ANRIL, LncRNA MEG3 and inflammatory factors (IFN-γ, IL-6, IL-18 and IL-1β) were detected using enzyme-linked immunosorbent assay (ELISA) at the first, second and seventh day of the onset of the disease. The correlation between serum LncRNA ANRIL, LncRNA MEG3 and inflammatory factor levels and neurological impairment at each time point was analyzed by Spearman correlation analysis.Results:Among 52 patients, mild group had 22 cases (NIHSS score <5 scores), and moderate-to-severe group had 30 cases (NIHSS score ≥5 scores). In acute ischemic stroke patients with moderate-to-severe group, the expression level of LncRNA MEG3 was higher than in the mild group, but the intergroup difference did not reach statistical significance ( P>0.05). LncRNA ANRIL, LncRNA MEG3, IFN-γ, IL-18 and IL-1β peaked at the same time point in acute ischemic stroke patients, all within second day of the onset of the disease. Spearman correlation analysis showed that the serum LncRNA MEG3 level on the first day of the onset of the disease was significantly positively correlated with NIHSS score ( P = 0.006), and serum LncRNA ANRIL level on seventh day was significantly positively correlated with NIHSS score ( P = 0.049). Conclusions:Serum LncRNA ANRIL, LncRNA MEG3 and inflammatory factors (IL-18, IL-1β and IFN-γ) are highly expressed in patients with acute ischemic stroke, peaking on the second day of onset. LncRNA MEG3 levels on the first day of onset and LncRNA ANRIL levels on the seventh day of onset are helpful in determining the degree of neurological impairment in patients with acute ischemic stroke.

Cancer is the main cause of death,and drug therapy has greatly improved the effectiveness of anti-tumor treatment.However,there are problems such as high adverse reactions and the risk of developing drug resistance after long-term use.There is an urgent need to seek new drug targets.Human antigen R(HuR),as an RNA binding protein,promotes the whole process of tumor occurrence,development and metastasis through post transcriptional regulation of mRNA stability,and HuR is general-ly highly expressed in tumor tissue,making it a new target for an-ti-tumor therapy and a standard for prognosis evaluation.Tradi-tional Chinese medicine formulas and their various chemical components can inhibit tumor proliferation,induce tumor cell ap-optosis,inhibit angiogenesis,suppress immune escape,and re-verse tumor drug resistance by regulating HuR activity.This re-view summarizes the importance of HuR in regulation of tumor progression,as well as analyzes the mechanisms of the antitumor effects through active ingredients of Chinese medicine with the regulation of HuR.It is expected to provide new ideas for tumor therapy and guidance for the development of HuR-targeted anti-tumor drugs.

Objective:To explore the potential prognostic value of the HAMP(hepcidin)gene in gastric adenocarci-noma and its correlation with immune infiltration in gastric cancer.Methods:This study systematically analyzed the ex-pression characteristics of the HAMP gene using bioinformatics approaches based on mRNA data from 448 gastric ad-enocarcinoma tissues and non-tumor tissues in the TCGA database.Firstly,the cBioPortal platform was employed to analyze the genetic variation features of the HAMP gene,and the LinkedOmics database was used to evaluate the corre-lation between its methylation status and expression levels.Kaplan-Meier survival analysis with log-rank test was per-formed to assess the relationship between HAMP expression levels and patient prognosis.Furthermore,by integrating TIMER2.0 and TISIDB databases,we systematically evaluated the correlation between HAMP expression and immune-related genes as well as immune cell infiltration.Gene Set Enrichment Analysis(GSEA)was conducted to investigate HAMP-associated signaling pathway characteristics.Finally,STRING and Gepia databases were utilized to construct a protein-protein interaction network of HAMP and identify core interacting genes,comprehensively evaluating the role of HAMP in immune infiltration in gastric adenocarcinoma.Results:The expression level of HAMP was significantly higher in gastric adenocarcinoma tissues compared to normal tissues(P<0.01),and its elevated expression was strongly associ-ated with poor patient prognosis,manifested by significantly shorter overall survival(OS),progression-free survival(PFS),and post-progression survival(PPS)(all P<0.05).Genomic analysis revealed that HAMP mutations in gastric cancer were predominantly amplification-type,and its methylation level showed a positive correlation with mRNA expression(r=0.14,P<0.001).Immunological analysis demonstrated that high HAMP expression was significantly correlated with multiple key immune checkpoint molecules(PD-1:rho=0.274;PD-L1:rho=0.211;CTLA-4:rho=0.199,all P<0.001)and immune cell infiltration(dendritic cells:r=0.548;macrophages:r=0.414;neutrophils:r=0.374,all P<0.001).Pathway enrichment analy-sis indicated that the high HAMP expression group was significantly enriched in immune-related pathways including anti-gen presentation and NK cell-mediated cytotoxicity.Furthermore,protein-protein interaction network analysis identified core interacting genes such as TREM2 and TYROBP,suggesting that HAMP may participate in tumor immune regulation through specific molecular networks.Conclusion:HAMP is highly expressed in gastric cancer,and its high expression significantly reduces the survival time of gastric adenocarcinoma patients,demonstrating prognostic value.HAMP ex-pression is positively correlated with most immune-related genes in STAD and significantly associated with the abun-dance of multiple immune cell infiltration levels,serving as an independent prognostic factor related to immune infiltration.

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.

Objective To investigate the effects of Echinococcus multilocularis infection on levels of memory T (Tm) cells and their subsets in lymph nodes of mice at different stages of infection, so as to provide new insights into immunotherapy for alveolarechinococcosis. MethodsTwenty-four C57BL/6J mice aged 6 to 9 weeks were randomly divided into the infection group and the control group, of 12 mice in each group. Mice in the infection group were administered with 3 000 E. multilocularis protoscoleces via portal venous injection, while animals in the control group were administered with an equal volume of physiological saline. Three mice from each group were sacrificed 4, 12 weeks and 24 weeks post-infection, and lymph nodes were sampled and stained with hematoxylin and eosin (HE) to investigate the histopathological changes of mouse lymph nodes in the infection group. The expression and localization of T lymphocyte surface markers CD3, CD4, and CD8 were observed in mouse lymph nodes using immunohistochemical staining. In addition, lymphocyte suspensions were prepared from mouse lymph nodes in both groups at different time points post-infection, and the levels of Tm cell subsets and their secreted cytokines were detected using flow cytometry. Results HE staining showed diffuse structural alterations in the subcapsular cortical and paracortical regions of mouse lymph nodes in the infection group 4 weeks post-infection with E. multilocularis. Immunohistochemical staining detected CD3, CD4 and CD8 expression in mouse lymph nodes in both groups. Flow cytometry revealed higher proportions of CD4⁺ Tm cells [(55.3 ± 4.8)% vs. (38.8 ± 6.1)%; t = -4.259, P < 0.05] and CD4⁺ tissue-resident Tm (Trm) cells [(57.7 ± 3.7)% vs. (34.1 ± 11.2)%; t = -3.990, P < 0.05] in mouse lymph nodes in the infection group than in the control group 4 weeks post-infection, and higher proportions of CD4⁺ Tm cells [(34.6 ± 3.2)% vs. (23.3 ± 7.5)%; t = -2.764, P < 0.05] and CD4⁺ Trm cells [(44.0 ± 1.9)% vs. (31.2 ± 1.5)%; t = -4.039, P < 0.05] in mouse lymph nodes in the infection group than in the control group 24 weeks post-infection. The proportions of CD8⁺ Tm cells were higher in the infection group than in the control group 4 weeks [(56.8 ± 2.7)% vs. (43.9 ± 5.2)%; t = -4.416, P < 0.01] and 12 weeks post-infection [(25.4 ± 2.7)% vs. (12.0 ± 2.6)%; t = -2.552, P < 0.05], while the proportions of tumor necrosis factor (TNF)-α⁺ CD4⁺ T cells [(15.7 ± 5.0)% vs. (49.4 ± 6.4)%; t = 7.150, P < 0.01], TNF-α⁺CD8⁺ T cells [(20.7 ± 5.5)% vs. (57.5 ± 8.4)%; t = -6.694, P < 0.01], and TNF-α⁺ CD8⁺ Tm cells [7.0% (1.0%) vs. 31.0% (11.0%); Z = -2.236, P < 0.05] were lower in the infection group than in the control group 24 weeks post-infection. Conclusions Tm cells levels are consistently increased in lymph nodes of mice at different stages of E. multilocularis infection, with Trm cells as the predominantly elevated subset. The impaired capacity of CD8⁺ Tm cells to secrete the effector molecule TNF-α in mouse lymph nodes at the late-stage infection may facilitate chronic parasitism of E. multilocularis.
