OBJECTIVE: To analyze the efficacy and safety of decitabine-based myeloablative preconditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with acute myeloid leukemia (AML). METHODS: The clinical characteristics and efficacy of 115 AML patients who underwent allo-HSCT at the First Medical Center of Chinese PLA General Hospital from August 2018 to August 2022 were retrospectively analyzed, including 37 patients treated with decitabine conditioning regimen (decitabine group) and 78 patients without decitabine conditioning regimen (non-decitabine group). The cumulative incidence of relapse (CIR), overall survival (OS), leukemia-free survival (LFS), non-relapse mortality (NRM) and graft versus host disease (GVHD) were analyzed. RESULTS: For the patients in first complete remission (CR1) state before allo-HSCT, the 1-year relapse rates of decitabine group(22 cases) and non-decitabine group(69 cases) were 9.1% and 29.6%, respectively, the difference was statistically significant(P =0.042). The 1-year cumulative incidence of acute graft-versus-host disease (aGVHD) in decitabine group and non-decitabine group was 62.2% and 70.5%, respectively, and the 1-year cumulative incidence of chronic inhibitor-versus-host disease (cGVHD) was 18.9% and 14.1%, respectively, there were no significant differences in the incidence of aGVHD and cGVHD between the two groups (P >0.05). Of the 115 patients, there were no significantly differences in the 1-year CIR(21.7% vs 28.8%, P =0.866), NRM(10.9% vs 3.9%, P =0.203), OS(75.2% vs 83.8%, P =0.131) and LFS(74.6% vs 69.1%, P =0.912) between the decitabine group(37 cases) and the non-decitabine group(78 cases). CONCLUSION Decitabine-based conditioning regimen could reduce the relapse rate of AML CR1 patients with good safety.

The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital. We have implemented the localized deployment of three models: Tianhe "Tianyuan", WiNGPT, and DeepSeek. The second is to create a digital avatar of the chief physician/chief physician's voice and image by integrating multimodal intelligent interaction technology. With generative intelligence as the core, this solution provides patients with a visual medical interaction solution. The third is to achieve deep adaptation between generative intelligence and the entire process of patient medical treatment. In this project, we have developed assistant tools such as intelligent inquiry, intelligent diagnosis and recognition, intelligent treatment plan generation, and intelligent assisted medical record generation to improve the safety, quality, and efficiency of the diagnosis and treatment process. This study introduces the content of a full-process disease diagnosis and treatment assistance system, aiming to provide references and insights for the digital transformation of the healthcare industry.

Objective To investigate the protective effect of paravertebral nerve block combined with general anesthesia on liver injury after laparoscopic hepatectomy(LH).Methods A randomized controlled trial was conducted on 51 patients undergoing LH in our hospital between April and August 2024.They were randomly divided into control group(n=25,general anesthesia)and paravertebral block group(n=26,paravertebral nerve block before general anesthesia induction).Beside anesthesia,they received same other medical treatment.The following indicators were compared between the 2 groups,that is,serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBIL)and albumin(ALB),and systemic-immune inflammation(SII)index within 7 d before and on the 1st and 2nd days after surgery;heart rate and mean arterial pressure(MAP)before anesthesia induction(T1),before pneumoperitoneum establishment(T2),pneumoperitoneum establishment(T3),and at the first hilar occlusion(T4);usages of intraoperative norepinephrine,sevoflurane,and analgesic drugs 24 h postoperatively;as well as operation time,extubation time,and lengths of postanesthesia care unit(PACU)stay and hospital stay.Results The paravertebral block group had significantly lower ALT on the 1st day after surgery[178.40(126.55,325.86)vs 292.20(197.20,468.95)U/L],SII on the 2nd day after surgery[704.13(486.61,1 078.59)vs 1 075.09(753.80,1 614.38)],and amount of analgesic drugs in 24 h after surgery[29.70(27.37,32.07)vs 31.99(28.92,40.81)mg],and decreased MAP level at T3 and T4,early extubation,and shorter lengths of PACU stay and hospital stay when compared with the control group(all P<0.05).Conclusion Paravertebral nerve block combined with general anesthesia can reduce inflammatory responses,relieve postoperative pain,stabilize hemodynamics for patients undergoing LH,and thereby alleviate postoperative liver injury in them.

Objective:To explore the mechanism of Shiwei Chaihu Shugan Powder in the treatment of breast hyperplasia using network pharmacology; To verify the mechanism of Shiwei Chaihu Shugan Powder in the treatment of breast hyperplasia through animal experiments.Methods:The active components and potential targets of Shiwei Chaihu Shugan Powder were searched in TCMSP and Uniprot databases. Breast hyperplasia genes were searched in GeneCards and OMIM databases. The intersection targets were obtained by online tool Venny, and the "drug-component-target" network was constructed by Cytoscape 3.8.2 software. The protein interaction (PPI) network was constructed using the String platform, and GO function and KEGG pathway enrichment analysis were performed using the DAVID annotation database. Molecular docking was performed using PDB, PubChem database, PyMOL 2.1 and AutoDockvina 1.2.5 software to predict the biological mechanism of Shiwei Chaihu Shugan Powder in the treatment of breast hyperplasia. Rats were divided into blank group, model group, tamoxifen group and Shiwei Chaihu Shugan Powder low-, medium- and high-dosage groups according to the random number table method, with 6 rats in each group. Except for the blank group, the other groups were prepared with the modified estrogen-progesterone-induced rat mammary hyperplasia model. Shiwei Chaihu Shugan Powder low-, medium- and high-dosage groups were intragastrically administered with Shiwei Chaihu Shugan Powder solution at 7.425 g/kg, 14.850 g/kg, and 29.700 g/kg respectively, while the tamoxifen group was intragastrically administered with 2.1 mg/kg tamoxifen. The blank group and the model group were intragastrically administered with the same volume of drinking water, once a day, for consecutive 28 d. The thickness of the mammary gland was measured by small animal ultrasound. The height and width of the nipples were measured by vernier calipers. The levels of serum E2 and P were detected by ELISA. The morphology of mammary tissue was observed by HE staining. The expressions of ERα, ERβ, SRC-1 and CBP/p300 proteins were detected by Western blot.Results:A total of 92 active components and 274 disease-drug intersection targets were screened out. GO functional enrichment analysis showed that Shiwei Chaihu Shugan Powder was closely related to positive regulation of gene expression, positive regulation of RNA polymerase Ⅱ promoter transcription, signal transduction, negative regulation of apoptosis process, response to heterogeneous stimulation, and regulation of hormone levels. KEGG enrichment analysis showed that the core targets might be related to NF-κB signaling pathway, MAPK signaling pathway, AGE-RAGE signaling pathway, PI3K/Akt signaling pathway, and regulating hormone levels. Molecular docking results showed that the core components had a good binding energy with the core target and a stable conformation. Compared with the model group, the thickness of the mammary gland in the tamoxifen group and Shiwei Chaihu Shugan Powder low-, medium- and high-dosage groups decreased ( P<0.01), the serum P level increased ( P<0.05), the expressions of ERα, SRC-1, and CBP/p300 proteins decreased ( P<0.01), and the expression of ERβ protein increased ( P<0.01); the height of the nipples in the Shiwei Chaihu Shugan Powder medium- and high-dosage groups and the tamoxifen group decreased ( P<0.01), and the serum E2 level increased ( P<0.05). Conclusion:Shiwei Chaihu Shugan Powder may play a role in the treatment of breast hyperplasia by regulating the levels of estrogen and related proteins.

Objective To investigate the pathogenesis of high-altitude cerebral edema(HACE)and develop new therapeutic strategies.Methods Male Sprague-Dawley(SD)rats of 6 weeks old were selected and placed in a hypobaric chamber.The rats were exposed to the high-altitude environment of 7000 m above sea level for 3 days for HACE modeling.Whether the HACE model was successfully established in the rats was evaluated by measuring brain water content,the degree of disruption to the blood-brain barrier(BBB),and brain tissue Nissl staining.The experimental animals were divided into four groups,with 28 rats in each group.The blank control group was exposed to a normobaric and normoxic environment simulating the conditions at 500 m above sea level for 3 d.The other groups,including a model group(the HACE group),a bumetanide group(the positive control group),and a XH-6003 treatment group,were placed at an altitude of 7 000 m above sea level and were injected with normal saline,bumetanide,and XH-6003,a new type of Na-K-2C1 cotransporter 1(NKCC1)inhibitor,via the tail vein,respectively,twice daily for 3 d.The experimental animals were taken out of the hypobaric chamber for testing after 3 d.The primary outcome measures included brain water content,BBB permeability,changes in brain tissue morphology,and the expression levels of aquaporin-4(AQP4)and NKCC1.The secondary outcome measures included behavioral changes,apoptosis,and oxidative stress markers.Results The HACE rat model was successfully established.The model group exhibited increased brain water content(P＜0.0001),BBB disruption(P＜0.0001),impairment in learning skills and memory(P＜0.001),and anxiety/depression-like behaviors(P＜0.01).qPCR results showed significantly increased expression of NKCC1 and AQP4 in the brain tissue of the model group(P＜0.01).Pathology examination revealed neuronal and glial cell damage in the hippocampus of the model group(P＜0.01).Treatment with XH-6003,the NKCC1 inhibitor,reversed brain water content,BBB disruption,and neuronal and glial cell damage to a certain degree(P＜0.05),decreased the expression of NKCC1 and AQP4 in the brain tissue(P＜0.01),and inhibited apoptosis-related proteins.Among the oxidative stress indices,only glutathione(GSH)showed improvement(P＜0.001).Rats treated with XH-6003 showed functional improvement only in the time spent exploring novel objects,while other behavioral outcomes remained unchanged.Conclusion HACE is associated with the activation of the NKCC1/AQP4 pathway.Inhibition of this pathway alleviates brain edema,BBB disruption,and neuronal and glial cell damage.These findings suggest that XH-6003 holds potential as a therapeutic strategy for HACE at the cellular and molecular levels,but its effects in improving HACE-related behavioral disorders warrant further investigation.
