Diabetes mellitus （DM） is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells， posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs， including the eyes， heart， liver， kidneys， nerves， and feet， making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications， challenges such as high costs and adverse drug reactions remain. Thus， identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component， astragaloside Ⅳ， possesses various biological activities， including anti-inflammatory， antioxidant， and antiviral effects， as well as benefits for cardiac and cerebral function， nerve conduction， and myocardial protection. Meanwhile， the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a crucial role in regulating oxidative stress， inflammatory responses， apoptosis， and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications， leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally， it highlights its protective effects on basic cardiac function， inhibition of retinal cell damage， improvement of cerebral nerve dysfunction， reduction of chronic kidney and liver damage， and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer， astragaloside Ⅳ， in the treatment of DM and its complications.

This study sought to evaluate the efficacy and safety of venetoclax (Ven) in combination with tyrosine kinase inhibitors (TKI) and reduced-dose chemotherapy for the treatment of patients with minimal residual disease (MRD) -positive and relapsed/refractory (R/R) Ph-positive acute lymphoblastic leukemia (Ph + ALL). A retrospective analysis was conducted on the clinical data of 13 patients with MRD-positive and relapsed Ph + ALL admitted between July 2015 and February 2024 at the Affiliated Cancer Hospital of Zhengzhou University. The cohort included seven males and six females, with a median age of 50 years (range: 37-71 years). Reinduction therapy consisted of Ven and TKI administration combined with reduced-dose chemotherapy. Among the 13 patients, 10 were MRD-positive, and three had R/R disease. Of the MRD-positive group, nine (90%) achieved complete molecular response (CMR), with a median time to response of 47 days (range: 30-80) ; one patient did not respond. Among the three patients who had R/R, two (66.6%) achieved complete remission, while one patient was nonresponsive. The median overall survival (OS) and relapse-free survival (RFS) time for the entire cohort were 21.5 months and 7 months, respectively. In patients who achieved CMR, the median OS and RFS time were 35 months and 34 months, respectively. Grade ≥3 hematologic adverse events occurred in five patients (38.4%) ; however, hematopoietic function recovered in all cases, and no grade ≥3 infections or organ-related adverse reactions were observed. These findings suggest that Ven combined with TKI and reduced-dose chemotherapy may be an effective and tolerable therapeutic strategy for MRD-positive and R/R Ph + ALL, particularly in significantly improving MRD clearance rates.

Objective To analysis the efficacy and safety of antiviral therapy in patients with chronic hepatitis B virus in indeterminate phase based on the new guidelines(2022 Edition of the Guidelines for the Prevention and Treatment of Chronic Hepatitis B).Methods A total of 170 patients with newly diagnosed HBV infection who visited the Third People's Hospital of Kunming from August 1,2020,to July 31,2024,were selected as study subjects.The clinical indicators of patients with normal ALT in the indeterminate phase were analyzed after 12 weeks,24 weeks,and 48 weeks of antiviral treatment,as well as those who did not receive antiviral treatment for 48 weeks.Results(1)Among the 170 patients with normal ALT during the indeterminate phase of HBV infection,the treatment group consisted of 125 patients(36 HBeAg positive and 89 HBeAg negative),while the untreated group had 45 patients.In the treatment group,the HBV-DNA load and HBsAg titer decreased significantly after 48 weeks compared to before treatment,with statistically significant differences(both P<0.05).In the untreated group,the HBV-DNA load showed an upward trend,and the HBsAg titer slightly decreased,with statistically significant differences(both P<0.05).(2)The CVR rate in the treatment group after 48 weeks was 66.67%(24/36)for HBeAg positive patients and 95.51%(85/89)for HBeAg negative patients,with a statistically significant difference(P<0.05).(3)The treatment group showed a significant decrease in GGT and AFP after 48 weeks compared to before treatment,while the untreated group saw an increase in ALT,GGT,and AFP,with statistically significant differences(all P<0.05).(4)The fibrosis indicators APRI,FIB-4,and LSM in the treatment group significantly decreased after 48 weeks compared to before treatment,with statistically significant differences(all P<0.05).(5)The safety indicators CREA,blood calcium,and blood phosphorus in the treatment group significantly decreased after 48 weeks compared to before treatment,with statistically significant differences(all P<0.05).Conclusion Expanding the antiviral treatment indications according to the new guidelines for patients with normal ALT in the indeterminate phase of HBV infection demonstrates good efficacy in controlling HBV-DNA,improving CVR rates,and enhancing fibrosis indicators,while also showing favorable renal safety.However,there may be a risk of osteoporosis due to calcium and phosphorus metabolism disorders,necessitating enhanced monitoring and prevention.

Central nervous system(CNS)degenerative disorders refer to a spectrum of pathological alterations triggered by struc-tural damage to cerebral neural tissues,clinically manifested as diverse neurological dysfunction syndromes,including multiple sclerosis(MS),neurodegenerative diseases(NDs),and ische-mic stroke.The hallmark pathological features of these disorders involve irreversible neuronal damage and decompensation of functional neural networks,ultimately leading to progressive neurological deficits.Notably,with the accelerating global popu-lation aging,the incidence of these diseases has surged signifi-cantly.According to WHO statistics,they now rank among the top three global causes of disability and mortality.Current re-search has confirmed that the pathogenesis of CNS degenerative disorders exhibits high heterogeneity,encompassing multifaceted pathophysiological processes such as genetic predisposition,oxi-dative stress,protein misfolding,and metabolic dysregulation.This intricate pathogenic network not only complicates clinical differential diagnosis but also poses substantial challenges to the development of precision therapeutic strategies.Importantly,re-cent studies have revealed that mitochondrial homeostasis disrup-tion-induced inflammatory cascades(termed mitochondrial in-flammation)play a pivotal regulatory role in neurodegenerative progression.Key molecular mechanisms include impaired mito-phagy,aberrant mitochondrial DNA(mtDNA)release and NL-RP3 inflammasome activation.This review systematically deci-phers the molecular regulatory network of mitochondrial inflam-mation,with a focus on its biological effects in critical pathologi-cal events such as blood-brain barrier disruption,microglial hy-peractivation and neuronal apoptosis.The overarching aim is to provide a theoretical foundation for developing innovative thera-peutic strategies targeting mitochondrial homeostasis restoration.

Objective:To investigate the effect of extracorporeal membrane oxygenation (ECMO) in assisting neonates with complex congenital heart diseases (CHD) and the survival rate of the patients.Methods:A retrospective case-control study was made on 22 newborns with complex CHD assisted by ECMO during the perioperative period in Fuwai Central China Cardiovascular Hospital from January 2018 to June 2024.There were 19 males and 3 females in the newborns included, with an average age of (10.4±8.7) days (range: 1-26 days) and an average weight of (3.1±0.3) kg.Complex CHD included total anomalous pulmonary venous connection in 9 cases (40.9%), interrupted aortic arch and coarctation in 8 cases (36.4%), transposition of great arteries in 3 cases (13.6%), double outlet right ventricle in 1 case (4.5%) and cardiac tumor in 1 case (4.5%).The patients were divided into the <5 d group, 5-12 d group, and >12 d group according to the duration of ECMO support.Data were compared using the t-test or χ2 test. Results:There were 8 cases (36.4%) successfully weaned from ECMO support and 6 cases (27.3%) survived.ECMO support was used routinely in 15 cases (68.2%), and for extracorporeal cardiopulmonary resuscitation in 7 cases (31.8%).The duration of ECMO support was (5.9±3.7) days.There were no statistically differences in age, weight, gender, disease composition, operation time, cardiopulmonary bypass time, cross-clamp time, assistant time, blood routine, liver and kidney function and other biochemical indicators, preoperative cardiac ejection fraction value, procalcitonin, C-reactive protein and other infection indicators between the death group and the survival group (all P>0.05).The highest lactate values 24 hours before [(8.1±5.4) mmol/L] and after ECMO support [(10.5±7.1) mmol/L] in the survival group were significantly lower than those in the death group [(18.7±9.2) mmol/L, (21.3±8.6) mmol/L] ( t=2.606, P=0.018; t=2.729, P=0.013).It was found that the survival rate was 0/9 (0) in the <5 d group, 6/12 (50.0%) in the 5-12 d group, and 0/1 (0) in the >12 d group.The survival rate of the 5-12 d group was the highest, which was significantly higher than that of the <5 d group ( χ2=6.300, P=0.012). Conclusions:ECMO support is an effective treatment for severe circulatory failure in neonates with complex CHD in the perioperative period.The highest lactate levels 24 hours before and after ECMO support affect the survival rate.Patients receiving 5-12 d ECMO support can achieve the highest survival rate.

Objective:To compare the efficacy and safety of two induction regimens, homoharringtonine plus venetoclax and azacitidine (VHA) versus venetoclax and azacitidine (VA) , for newly diagnosed acute myeloid leukemia (AML) patients who are elderly or ineligible for intensive chemotherapy.Methods:We retrospectively analyzed the clinical data of 59 newly diagnosed AML patients treated with the VHA or VA regimen at Zhengzhou University Affiliated Cancer Hospital from September 2018 to July 2021. The cohort included 25 males and 34 females, with a median age of 63 years. The overall response rate (ORR) , composite complete remission (CRc) rate [CR+CR with incomplete hematologic recovery (CRi) ], minimal residual disease (MRD) negativity rate, overall survival (OS) , relapse-free survival (RFS) , and adverse events were compared between the two groups. Survival was estimated by the Kaplan-Meier method, and prognostic factors were evaluated using univariable and multivariable Cox regression.Results:At the end of the treatment, the ORR was 88.4% (23/26) in the VHA group [21 CR, 2 partial remissions (PR) ] and 90.9% (30/33) in the VA group (25 CR, 5 PR) , with no significant difference between the groups ( P=0.458) . The MRD negativity rates after one cycle of induction were 73.1% (19/26) in the VHA group and 60.6% (20/33) in the VA group, respectively ( P=0.315) . In the high-risk subgroup, the composite remission rates after one cycle were 78.6% (11/14) with VHA and 50.0% (5/10) with VA ( P=0.143) ; MRD negativity rates were 64.3% (9/14) and 20.0% (2/10) , respectively ( P=0.032) . The main adverse events were myelosuppression, gastrointestinal reactions, and infections during neutropenia. Rates of grade 3-4 neutropenia and decreased hemoglobin were similar between groups, whereas grade 3-4 thrombocytopenia was more frequent with VHA than with VA (76.9% vs 45.5%, P=0.015) . With a median follow-up of 13 months (range, 1-59) , 1 year RFS was 69.9% (95% CI: 53.1%-92.2%) with VHA and 55.6% (95% CI: 40.1%-77.1%) with VA ( P=0.305) . The 1 year OS rates were 91.7% (95% CI: 77.3%-100.0%) and 58.2% (95% CI: 41.7%-81.4%) , respectively ( P=0.024) . Among high risk patients, 1 year RFS and OS were higher with VHA than with VA (RFS: 66.2% vs 37.5%, P=0.046; OS: 85.7% vs 48.0%, P=0.011) . Undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) significantly improved RFS and OS ( P=0.027 and 0.047, respectively) . On multivariable analysis, ELN risk classification and MRD negativity after the first cycle were independent prognostic factors for RFS. Treatment regimen (VHA vs VA) , MRD negativity after the first cycle, and receipt of transplantation were independent prognostic factors for OS. Conclusion:VHA provides clinical benefit in newly diagnosed AML patients who are unfit for intensive chemotherapy and in older adults, with particularly favorable outcomes in high risk patients; sequential allo-HSCT confers additional benefit, and associated adverse events are manageable.

Connective tissue disease(CTD)is based on chronic inflammation of blood vessels and connective tissue,often involving multiple systems.The basic pathological changes are necrotizing vasculitis,myxedema,fibrin like deformation,etc.It belongs to systemic autoimmune disease.Due to the complex pathogenesis and heterogeneity of CTD,developing personalized manage-ment strategies remains extremely challenging.Therefore,exploring the new mechanisms and treatment targets of CTD is the focus of CTD research work.In recent years,with the continuous deepening of research on CTD,it has been discovered that there is a new form of cell death in the pathological process of CTD,namely copper death.Similar to ferroptosis,copper induces cytotoxicity mediated cell death through increased mitochondrial dependent energy metabolism and accumulation of reactive oxygen species.This article mainly attempts to explore the relationship between copper death and the pathological mechanism of confirmed CTD,as well as its impact on various immune cells,as well as the opportunities and challenges faced by therapeutic targets and clinical drugs.

Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.
