Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality, characterized by poor prognosis due to its high proliferative and invasive potential. Tumor metabolic reprogramming, particularly involving glucose metabolism, is essential for tumor survival. This study investigates the role of the Hippo pathway effector transcriptional co-activator with PDZ-binding motif (TAZ) in regulating gluconeogenesis and promoting tumorigenesis in HCC. Methods: TAZ expression in HCC was analyzed using The Cancer Genome Atlas data and validated in clinical samples and cell lines. TAZ was overexpressed or silenced in HCC cell lines to evaluate its effects on cell proliferation, apoptosis, migration, and invasion. The expression and prognostic relevance of the gluconeogenesis-related genes phosphoenolpyruvate carboxykinase 1 (PCK1) and glucose-6-phosphatase (G6PC) were examined, along with their correlation with TAZ expression. Tumor growth was assessed in nude mice. Interactions between TAZ and the glucocorticoid receptor (GR) were investigated using co-immunoprecipitation, immunofluorescence, and chromatin immunoprecipitation assays. Results: TAZ was significantly upregulated in HCC tissues and cell lines. TAZ overexpression enhanced proliferation, reduced apoptosis, and promoted migration and invasion. In contrast, PCK1 and G6PC were downregulated in HCC and showed a negative correlation with TAZ expression. Conclusion TAZ modulates gluconeogenesis and accelerates tumor growth, whereas its knockdown attenuates tumor progression. TAZ interacts with GR, suppressing its transcriptional activity on gluconeogenic gene promoters.

Objective: To explore the correlation between the composition of bone marrow lymphocyte subsets and the clinical attributes observed in de novo AML patients, as well as their influence on prognosis. Methods: A detailed study was carried out on a cohort of 191 de novo acute myeloid leukemia patients who were admitted to our medical center between October 2022 and September 2024. In addition, a group of 24 patients with iron deficiency anemia individuals was carefully chosen as the control cohort. The proportions of lymphocyte subsets within the bone marrow of de novo AML patients were analyzed. Furthermore, an in-depth analysis was performed to investigate the association between the expression levels of these subsets in de novo AML patients and their clinical attributes, as well as their prognostic implications. Results: The proportion of CD19 and CD56 lymphocytes within the bone marrow of de novo AML patients significantly diminished compared to the control cohort (8.5% vs 13.2% P<0.05, and 15.5% vs 18.0%, P<0.05). Conversely, no significant discrepancies were observed in the CD3 , CD3 CD4 , and CD3 CD8 lymphocyte percentages between the AML patients and control group (71.7% vs 72.1%, 32.5% vs 33.7% and 32.8% vs 35.7%, P>0.05). When analyzing the relationships between lymphocyte subsets within the bone marrow of de novo patients and their respective clinical characteristics, patients aged 60 years and above exhibited diminished percentages of CD3 CD8 lymphocytes in the bone marrow compared to their younger counterparts (31.6% vs 34.1%, P<0.05), while the CD56 lymphocyte subsets demonstrated an increased prevalence (17.2% vs 14.4%, P<0.05). Furthermore, patients with leukocytosis (WBC≥100×10 /L) presented lower levels of CD3 and CD3 CD4 lymphocytes in the bone marrow compared with those without it (65.3% vs 72.9% P<0.05, and 28.9% vs 33.2%, P<0.05), respectively. The AML1-ETO fusion gene-positive cohort exhibited a higher prevalence of CD3 CD8 lymphocytes in the bone marrow than in the negative group (38.2% vs 32.3%, P<0.05), whereas the FLT3-ITD mutation-positive group presented a decreased prevalence of CD56 lymphocytes compared with the negative group (12.4% vs 16.8%, P<0.05). In addition, the NPM1 mutation-positive group demonstrated lower levels of CD3 CD8 lymphocytes in the bone marrow than in the negative group (29.1% vs 33.3%, P<0.05). Variables such as tumor protein p53(TP53) mutation positive, the absence of hematopoietic stem cell transplantation, and CD3 CD4 lymphocyte proportions below 25% were identified as independent adverse prognostic indicators for AML patients (P<0.05). Conclusion: The pathogenesis of AML is closely associated with an imbalance in bone marrow lymphocyte subsets. The FLT3-ITD mutation potentially contributes to the dysregulation of CD56 lymphocyte subset expression. The AML1-ETO fusion gene and NPM1 mutation are implicated in the abnormal expression of CD3 CD8 lymphocytes within the bone marrow. Moreover, the percentage of CD3 CD4 lymphocytes in the bone marrow serves as a prognostic factor for de novo AML patients.

Objective:To analyze the survival outcomes and prognostic factors of patients with ovarian carcino-sarcoma(OCS)based on SEER database.Methods:The data of 1285 OCS patients from 2000 to 2018 in SEER database were retrospectively analyzed.Univariate and multivariate Cox proportional hazards models were used to evaluate the prognostic factors associated with overall survival(OS)and cancer specific survival(CSS).Kap-lan-Meier survival curve was drawn to evaluate the survival analysis of patients' prognosis after clinical treatment.Results:①The study cohort included a total of 1285 OCS patients,The mean age of these patients was 66.21±11.71 years.Most patients had already experienced regional(22.80％)or distant(72.22％)metastasis at the time of diagnosis.②Multivariate Cox regression revealed,SEER stage of regional or distant metastasis,no surger-y,no chemotherapy,and no lymphadenectomy were independent risk factors for both patient OS and CSS(HR＞1,P＜0.05).Age ≥67 years was an independent risk factor for OS(HR＞1,P＜0.05).Age ≥ 83 years was an in-dependent risk factors for CSS(HR＞1,P＜0.05).③Kaplan-Meier survival analysis showed that among surgical patients with adjacent tissue invasion or distant metastasis had significantly better overall survival rate after lymph node dissection than those without(P＜0.001);We didn't see the significantly different effects of lymphadenecto-my on patients with localized disease(P=0.266).Among all patients who underwent surgery,the overall survival rate of all patients who received adjuvant chemotherapy after surgery was significantly better than that of those who did not(P＜0.001).Conclusions:Prognosis of OCS patients is associated with age,SEER comprehensive stage,surgery status,chemotherapy status,lymphadenectomy status.Patients with OCS who underwent cytore-ductive surgery and adjuvant chemotherapy had a better prognosis.However,it is questionable whether lymph-adenectomy is necessary in OCS patients with very early stage.

Objective: To construct a 5G unmanned aerial vehicle (UAV) airport platform for blood transportation and explore its feasibility and advantages within the blood emergency support system. Methods: Based on 5G high-speed network transmission technology, a UAV management system was designed to achieve a closed-loop management of the entire transportation process, including blood distribution, route information, flight status, emergency dispatch, hospital reception, real-time temperature monitoring, and video surveillance. Integrated with an open UAV airport, the first "5G UAV Blood Transportation Intelligent Airport Platform" was established. Results: At present, the platform has settled in 2 sets of UAV systems, established 17 routes, and carried out regular UAV blood transportation services for 15 hospitals. From January 1, 2024 to June 30, 2025, a total of 12 134 sorties were completed, with a total transported blood weight of 7 692.38 kg, including 25 500 units of red blood cells, 3 824.5 units of platelets, 1 350 370 mL of plasma, and 10 810 units of cryoprecipitate. Compared to land transportation, UAV delivery saved an average of 46.8 minutes during rush hours (maximum: 89.3 minutes) and an average of 32.3 minutes during non-rush hours (maximum: 59.1 minutes). In terms of the quality of UAV blood transportation, the temperature of suspended red blood cells was between 4 and 8℃, that of platelets was between 20 and 24℃, and that of plasma was below 0℃. No damage has occurred so far. Conclusion: The UAV blood transportation platform can stably provide blood delivery services during both routine and emergency conditions, ensuring timely blood delivery and stable blood quality.

ObjectiveTo compare the contents and relative molecular weight distributions of proteins and polypeptides in Naoxuekang dropping pills， Huoxue Tongmai capsules and Maixuekang capsules of Hirudo single medicinal preparations， to evaluate the in vitro anticoagulant， antiplatelet and fibrinolytic activities of the three preparations， and to investigate the effects of temperature， pH and digestive enzymes on the anticoagulant activities of the three preparations. MethodsThe contents of soluble proteins and polypeptides in the three preparations were determined by bicinchoninic acid assay（BCA） and Bradford method， and the relative molecular weight distributions of the three preparations were determined by electrophoresis combined with gel chromatography. The antithrombin activity of the three preparations was evaluated by fibrinogen-thrombin time（Fibg-TT） method， and their anticoagulant activities were further assessed by the elongations of activated partial thromboplastin time（APTT）， prothrombin time（PT） and thrombin time（TT）. The antiplatelet aggregation activities of the three preparations were measured by turbidimetry and the fibrinolytic activities were measured by fibrin plate method. Relative TT was used as index to investigate the effects of temperature， pH and digestive enzyme buffer on anticoagulant activities of the three preparations. ResultsAt the lowest single dosage， the contents of proteins and polypeptides were in the order of Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. Both Huoxue Tongmai capsules and Maixuekang capsules had 11 electrophoretic bands between 4.0 kDa and 90 kDa， the bands of Maixuekang capsules were more clear in the range of >25 kDa， and there was 1 obvious band at 14 kDa for the two capsules. Huoxue Tongmai capsules had one specific band at 9.0 kDa and Maixuekang capsules had one specific band at 48.0 kDa. Naoxuekang dropping pills only had 2 electrophoretic bands at 6.5 kDa and 8.5 kDa， primarily containing peptides below 2 kDa， most of which were oligopeptides. The anticoagulant activity concentrations of the three preparations exhibited a certain dose-dependent effect. At the lowest single dosage， The anticoagulant activity concentrations were ranked as Naoxuekang dropping pills>Huoxue Tongmai capsules>Maixuekang capsules. The prolongation effect of the three preparations on coagulation time was dose-dependent. At the same concentration， the prolongation effect of Naoxuekang dropping pills and Huoxue Tongmai capsules was APTT prolongation rate>TT prolongation rate>PT prolongation rate， whereas for Maixuekang capsules， the sequence was TT prolongation rate>APTT prolongation rate>PT lengthening rate. At the single minimum dosage， the order of APTT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules≈Naoxuekang dropping pills， the order of PT prolongation rate was Naoxuekang dropping pills≈Maixuekang capsules>Huoxue Tongmai capsules， and the order of TT prolongation rate was Maixuekang capsules>Huoxue Tongmai capsules>Naoxuekang dropping pills. The three preparations showed dose-dependent effects on platelet aggregation induced by adenosine diphosphate（ADP） and arachidonic acid（AA）， and the effect induced by ADP was stronger than that induced by AA. The anti-platelet aggregation effect of Naoxuekang dropping pills was significantly stronger than that of Maixuekang capsules（P<0.01）， whereas Huoxue Tongmai capsules had the effect of promoting platelet aggregation. None of the three preparations had the ability to dissolve fibrin. The anticoagulant activity of Naoxuekang dropping pills was least affected by heating， while the activities of the two capsules decreased significantly within 5 min above 80 ℃， and continued to decrease within 2 h. Compared with pure water， the anticoagulant activities of the three preparations could be increased by 1-3 times under strong acidity（pH 1-3）. In the pepsin buffer， the anticoagulant activity of Naoxuekang dropping pills could be increased by 1-3 times， while the anticoagulant activities of Huoxue Tongmai capsules and Maxuekang capsules were significantly decreased， the lowest levels were about 60% and 20%， respectively. In trypsin buffer， the anticoagulant activities of Naoxuekang dropping pills， Huoxue Tongmai capsules and Maixuekang capsules decreased significantly， and the lowest levels decreased to about 41%， 41% and 35%， respectively. ConclusionThe contents of proteins and polypeptides and relative molecular weights of the preparations derived from lyophilized fresh Hirudo powder， dried Hirudo powder and reflux extract of Hirudo decrease sequentially， and the anticoagulant activity decrease gradually， but the anticoagulant pathway is different. And the anti-platelet aggregation activity of the reflux extract is significantly enhanced. The heat resistance and gastrointestinal stability of the three preparations increase successively， and the first two are suitable for enteric-soluble preparations， while the latter is suitable for routine oral administration. The above results can provide data reference for the rationality of different preparation methods， active substances， pharmacodynamics and mechanism of Hirudo preparations.

PANoptosis, a newly defined form of cell death, is characterized by the simultaneous occurrence and crosstalk of apoptosis, pyroptosis, and necroptosis. It has emerged as a promising therapeutic target for various diseases. Ovarian dysfunction is marked by oligomenorrhea or amenorrhea, elevated gonadotropin levels, and diminished estrogen levels, often accompanying subfertility or infertility. Additionally, it can manifest with perimenopausal syndrome and increase the risks of osteoporosis, cardiovascular disease, and cognitive impairments, seriously impacting patients' quality of life. While current studies have reported that ovarian hypofunction is associated with apoptosis, pyroptosis, or necroptosis, a systematic investigation into the relationship between PANoptosis and ovarian hypofunction is still absent. This review aims to elucidate the potential link between these two phenomena, providing new insights into the mechanisms underlying ovarian hypofunction and potential treatment strategies.

OBJECTIVES: We present a new low-dose CT reconstruction method using sub-pixel and anisotropic diffusion. METHODS: The sub-pixel intensity values and their second-order differences were obtained using linear interpolation techniques, and the new gradient information was then embedded into an anisotropic diffusion process, which was introduced into a penalty-weighted least squares model to reduce the noise in low-dose CT projection data. The high-quality CT image was finally reconstructed using the classical filtered back-projection (FBP) algorithm from the estimated data. RESULTS: In the Shepp-Logan phantom experiments, the structural similarity (SSIM) index of the CT image reconstructed by the proposed algorithm, as compared with FBP, PWLS-Gibbs and PWLS-TV algorithms, was increased by 28.13%, 5.49%, and 0.91%, the feature similarity (FSIM) index was increased by 21.08%, 1.78%, and 1.36%, and the root mean square error (RMSE) was reduced by 69.59%, 18.96%, and 3.90%, respectively. In the digital XCAT phantom experiments, the SSIM index of the CT image reconstructed by the proposed algorithm, as compared with FBP, PWLS-Gibbs and PWLS-TV algorithms, was increased by 14.24%, 1.43% and 7.89%, the FSIM index was increased by 9.61%, 1.78% and 5.66%, and the RMSE was reduced by 26.88%, 9.41% and 18.39%, respectively. In clinical experiments, the SSIM index of the image reconstructed using the proposed algorithm was increased by 19.24%, 15.63% and 3.68%, the FSIM index was increased by 4.30%, 2.92% and 0.43%, and the RMSE was reduced by 44.60%, 36.84% and 15.22% in comparison with FBP, PWLS-Gibbs and PWLS-TV algorithms, respectively. CONCLUSIONS The proposed method can effectively reduce the noises and artifacts while maintaining the structural details in low-dose CT images.

Objective::To examine the impact of hypertensive disorders of pregnancy (HDP) on offspring metabolomics.Methods::We searched five databases: PubMed, Ovid Embase, MEDLINE, Web of Science, and China National Knowledge Infrastructure, and included studies that reported metabolomics among human offspring born to HDP-complicated pregnancies.Results::Database search yielded 4054 articles, and after full-text screening, ten observational studies met inclusion criteria. Half of the studies had a sample size of less than 100 and were all observational studies in preeclampsia (PE) and gestational hypertension.Neonates were the most focused group in all included studies. Offspring born to HDP-complicated pregnancies exhibited statistically significant variations in blood metabolomics compared to their counterparts, characterized by amino acids, lipids, carnitine, and others (e.g., 1α,25-(OH) 2-D). Most studies reported a significant increase in differential metabolites of offspring born to HDP-complicated pregnancies. Four studies ( n = 1109) measured lipids-related metabolites, and all consistently showed that offspring born to PE-complicated pregnancies had significantly higher concentrations than non-PE exposed offspring. Conclusion::The existing evidence suggests an intergenerational effect of HDP on offspring metabolomics. Long-term follow-up studies are needed to advance the health effects of related adverse health outcomes and inform the prevention of offspring’s health.
