As a distinctive resource of Chinese civilization， traditional Chinese medicine （TCM） technology transfer faces significant opportunities under the background of digital and intelligent transformation， while also being constrained by unique challenges such as the complexity of its theoretical system， lengthy industrial chains， and multidimensional policy restrictions， resulting in a "high-value-high-threshold" paradox. At present， TCM technology transfer is deeply trapped in a "threefold reluctance" dilemma， i.e.， unwillingness to transfer， inability to transfer， and lack of capacity to transfer. Specifically， the disconnection between scientific research evaluation systems and market demand leads to low conversion rates of research achievements， unclear ownership and compliance risks suppress innovation incentives， and the absence of professional services intensifies supply-demand mismatches. This article systematically analyzes the specific characteristics of TCM technology transfer and proposes a breakthrough pathway centered on full-chain digital and intelligent transformation. By integrating technologies such as intelligent sorting systems， blockchain-based traceability， and AI diagnostic models， the TCM ecosystem spanning "cultivation-production-service" can be reconstructed. In terms of standardization， promoting the progression from "experience-based data conversion" to "data standardization" and further to "intelligent standardization" is advocated to resolve quality control challenges. For example， a "three-no-one-full" certification system can strengthen quality trust. Policy coordination should focus on optimizing mechanisms for the transformation of scientific and technological achievements， while exploring intellectual property securitization and risk-sharing models to stimulate research momentum. In terms of internationalization， reliance on the Belt and Road Initiative platform to promote the export of geo-authentic medicinal material brands and standards is recommended to build a dual-driven model of "technology plus culture". Looking ahead， through the construction of national-level databases， the cultivation of interdisciplinary talent， and the mutual recognition of international standards， a new paradigm of "scientific intelligent manufacturing" can be formed， providing systematic solutions for the modernization of TCM and global health governance.

Ten-eleven translocation 2 （TET2）， as a core enzyme in epigenetic regulation， dynamically regulates the differentiation and function of CD4⁺ T cells by mediating DNA demethylation. Recent studies have shown that TET2 deficiency can promote the progression of autoimmune hepatitis （AIH） by disrupting the Th17/Treg balance and activating inflammatory signals along the gut-liver axis. This article systematically reviews the bridging role of TET2 between CD4⁺ T cells and gut microbiota， explores the molecular mechanisms by which it drives AIH through the gut microbiota-epigenetics-immunity network， and discusses the potential intervention strategies targeting the TET2-microbiota axis.

Standardizing the emergency assessment and management process for patients with implantable continuous-flow left ventricular assist device (LVAD) in emergency and intensive care settings is of great significance for reducing delays in diagnosis and treatment, lowering the mortality associated with LVAD-related emergencies, and improving overall prognosis and long-term survival. To this end, a multidisciplinary expert committee was convened to develop this consensus, integrating international evidence-based findings with clinical practice experience in China, with an emphasis on highlighting the characteristics of domestically manufactured devices. The aim is to establish an actionable standardized emergency management protocol to enhance clinical identification and response efficiency, reduce the risk of LVAD-related emergencies, and improve patient outcomes. Using a modified Delphi method, this consensus proposes a structured decision-making pathway that integrates an "ABC" rapid assessment with parallel device troubleshooting, prioritizing the use of point-of-care echocardiography for hemodynamic evaluation and complication assessment. Key emergency scenarios covered include low-flow alarms, pump thrombosis, right heart dysfunction, bleeding and anticoagulation imbalance, arrhythmias, and cardiac arrest. This consensus applies to implantable continuous-flow LVADs commonly used in China, including domestically manufactured devices such as Corheart 6, CH-VAD, EVAHEART, and HeartCon, as well as the imported device HeartMate 3.

Objective:To analyze the efficacy and safety of modified associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in the treatment of patients with primary liver cancer.Methods:Clinical data of 83 patients with hepatocellular carcinoma (HCC) undergoing hemihepatectomy in the Department of Hepatobiliary and Pancreatic Tumor Surgery of Gansu Provincial Cancer Hospital between January 2022 and November 2023 were retrospectively analyzed, including 53 males and 30 females, aged (54.0±6.5) years. According to the treatment protocol, patients were divided into the control group ( n=41), in which patients underwent traditional ALPPS, and the observation group ( n=42), in which patients underwent modified ALPPS (occlusion of portal venous branch using vascular clips, combined with radiofrequency ablation for physical separation of the diseased lobe, without liver mobilization). The completion rate of staged surgery, interval between surgeries, future liver remnant (FLR) growth rate at 7 days after first-stage surgery, alanine transaminase (ALT) and aspartate transaminase (AST) levels at 5 days after fisrt-stage surgery, and postoperative complications (ascites, nausea, and vomiting, etc.) were compared between the groups. Results:The completion rate of staged surgery was 95.2% (40/42) in the observation group and 90.2% (37/41) in the control group ( χ2=0.62, P=0.431). The ALT and AST levels at 5 days after first-stage surgery were (550.4±86.0) U/L and (327.1±52.8) U/L in the observation group, respectively, which were significantly lower than those in the control group (861.6±106.3) U/L and (533.8±73.7) U/L, respectively ( t=13.13 and P<0.001, t=12.93 and P<0.001). The FLR growth rate were higher in the observation group than that in the control group [(80.4±10.3)% vs (49.3±5.7)%; t=13.13, P<0.001] and the interval between procedures were also shorter in the observation group (10.9±2.1 vs 22.4±4.8, d; t=9.65, P<0.001). The intraoperative blood loss of the first-stage surgery was lower in the observation group than that in the control group (350.5±45.2 vs 825.5±21.7, ml; t=21.43, P<0.001). The total complication rates after the first-stage surgery were 11.9% (5/42) in the observation group and 19.5% (8/41) in the control group, while after the second-stage surgery, the complication rates were 7.5% (3/40) and 18.9% (7/37), respectively, with no statistically significant differences ( χ2=0.65 and P=0.419, χ2=1.81 and 0.177, respectively). Conclusion:The modified ALPPS offers better postoperative liver function, reduced surgical trauma, accelerated FLR growth, and a shorter interval between procedures, demonstrating a favorable safety in the treatment of primary liver cancer.

Objective To investigate the expression and clinical significance of serum microRNA-144-3p(miR-144-3p)and microRNA-126-3p(miR-126-3p)in patients with intracerebral hemorrhage(ICH).Methods From February 2022 to April 2023,120 ICH patients who underwent treatment at our hospital were recruited as the ICH group.They were separated into a good prognosis group and a poor prognosis group based on the modified Rankin Scale(mRS)score After 6 months treatment Additionally,110 healthy individuals who underwent physical examination at our hospital were included as the control group.Clinical data of patients were collected and analyzed.Enzyme linked immunosorbent assay(ELISA)was applied to detect serum levels of tumor necrosis factor-α(TNF-α)and vascular endothelial growth factor(VEGF)indicators.Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)was applied to detect the expression levels of serum miR-144-3p and miR-126-3p.Pearson method was applied to analyze the correlation between serum miR-144-3p,miR-126-3p,TNF-α,and VEGF levels in ICH patients.Multivariate Logistic regression was applied to analyze the factors affecting the prognosis of ICH patients.ROC curve was applied to analyze the predictive value of serum miR-144-3p and miR-126-3p for the prognosis of ICH patients.Results In the control group,the serum miR-144-3p was 1.02±0.02,the TNF-α was(19.15±6.79)pg/ml,the VEGF level was(1.05±0.18)ng/ml,and the serum miR-126-3p level was 1.04±0.05.The values in the ICH group were 2.12±0.23,(48.32±8.43)pg/ml,(6.56±1.49)ng/ml,and(0.53±0.12),respectively.There was a statistically significant difference between the two groups(P＜0.05).Pearson analysis results showed that serum miR-144-3p was positively correlated with TNF-α and VEGF levels in ICH patients(r=0.496,0.542,P＜0.05),while serum miR-126-3p was negatively correlated with TNF-α and VEGF levels(r=-0.493,-0.526,P＜0.05).There were significant differences in the serum levels of miR-144-3p,miR-126-3p,TNF-α,VEGF,and NIHSS score between different prognostic groups(P＜0.05).Multivariate logistic analysis revealed that serum miR-144-3p,miR-126-3p,TNF-α,and VEGF were all factors affecting the poor prognosis of ICH patients(P＜0.05).The area under the curve(AUC)of serum miR-144-3p,miR-126-3p,and combined prediction of prognosis in ICH patients was 0.851,0.886,and 0.952,respectively,the combined prediction of the two was more valuable(Zcombination-miR-144-3p=3.371,Zcombination-miR-126-3p=2.791,P＜0.05).Conclusion The expression of miR-144-3p in the serum of ICH patients increases,while the expression of miR-126-3p decreases.The two may serve as biological markers for predicting the prognosis of ICH patients,and the combination of the two is more valuable in predicting the prognosis of ICH patients.

Objective:To compare the impact of preoperative pulmonary vascular resistance(PVR) levels on the prognosis of patients undergoing left ventricular assist device(LVAD)implantation.Methods:A retrospective analysis was conducted on the clinical data of 33 patients among September 2021 and June 2024, who underwent LVAD implantation at Zhongshan Hospital, Fudan University. 29 males and 4 females, with a mean age of(53.61±9.65)years old. The cohort included 30 cases of dilated cardiomyopathy, 2 cases of ischemic cardiomyopathy, and 1 case of noncompaction cardiomyopathy. Patients were grouped based on a preoperative PVR threshold of 3 WU, Preoperative data from Swan-Ganz catheterization, liver and renal function indicators, as well as other relevant clinical parameters were recorded. Patients were followed up to assess differences in survival outcomes.Results:Preoperative PVR was elevated in 18 cases(60%)of the patients, with a mean preoperative PVR of(3.16±1.71)WU. Immediate postoperative right heart catheterization was performed in 20 patients, showing a significant reduction in PVR from(3.85±1.72)WU preoperatively to(1.80±1.38)WU postoperatively( P<0.05). The cardiac index improved significantly from(1.95±0.63)L·min -1·m -2 preoperatively to(4.25±1.26)L·min -1·m -2 postoperatively( P<0.001). The mean follow-up duration was(14.78±12.06)months, no significant difference in postoperative survival was observed between the two groups(100% vs. 80%, P=0.667). Conclusion:Increased pulmonary resistance is often secondary to left heart dysfunction. After the implantation of a LVAD, pulmonary resistance can be improved. For patients with relatively normal right heart function before surgery, elevated pulmonary resistance does not affect the short-term outcomes of the implantation.

To investigate the infection status of two arboviruses,akabane orthobunyavirus(AKAV)and bluetongue virus(BTV),in cattle herds of Guizhou Province,we employed the indirect ELISA method to detect AKAV and BTV antibody levels in the present experiment.A total of 1504 bovine serum samples from 37 large-scale farms and 88 free-range households from 26 districts or coun-ties of 7 cities(prefectures)of Guizhou Province were collected to detect AKAV antibody levels.Additionally,1 241 serum samples from 30 large-scale farms and 15 free-range households in 19 districts or counties of 3 cities(prefectures)were tested for BTV antibody levels.Moreover,two influencing factors,breeding mode and sampling season,were statistically analyzed for their effects.The results showed that the overall positive rate of AKAV antibodies was 11.64％(175/1 504),with individual positive rates of 13.20％(123/934)and 9.12％(52/570)in large-scale farms and free-range households,respectively.No significant differences were observed between the two groups.However,the farm positive rate(64.86％,24/37)in large-scale farms was significantly higher than that(26.14％,23/88)in free-range households.Seasonal statistics showed that the positive rate was highest during the summer season at 60.00％(12/20).The total positive rate of BTV antibodies was 25.42％(222/1 241).The farm positive rate and individual positive rate in free-range households were 66.67％(10/15)and 41.91％(57/136),respectively.For large-scale farms,these rates were 60.00％(18/30)and 14.93％(165/1 105),respectively.The individual pos-itive rate in free-range households was significantly higher than that in large-scale farms.Seasonal statistics showed that the positive rates in summer and autumn seasons were 50.00％(5/10)and 72.41％(21/29),respectively,both of which were significantly higher than those in winter and spring seasons.All these findings indicated that both AKAV and BTV were present to a certain ex-tent in Guizhou Province,with seasonality.Furthermore,differences were observed between the different breeding modes.Our results could provide a data reference for the formulation of preven-tion and control measures for the two insect-borne diseases.

To establish a rapid visual detection method for Akabane virus(AKAV)on site,specific primers and probes based on the S fragment of AKAV were designed in this experiment.Corre-sponding groups were added to the primers or probes to fulfil the requirement of the combination of recombinase polymerase amplification(RPA)with lateral flow dipstick(LFD).The reaction temperature and time,concentrations of the primer and probe were optimized to establish the RPA-LFD method for detecting AKAV.After that,the specificity,sensitivity and clinical reliability of the method were evaluated.The results showed that after 20 minutes of reaction at 37 ℃,the test results could be read on LFD paper.There was no cross reaction against blue tongue virus,Pasteurella multocida,bovine infectious rhinotracheitis virus and bovine Mycoplasma bovis,and the detection limit was 2.5 × 100 copies/μL of standard plasmid.Detection of clinical samples showed a consistent results with that by RT-PCR method.These findings indicated that the RPA-LFD method established had the advantages of good specificity,high sensitivity,simple operation and visualization,and could be applied to clinical detection,which provides new technical support for the rapid diagnosis and prevention and control of AKAV.
