Alzheimer's disease (AD), a prototypical neurodegenerative disorder, encompasses multifaceted pathological processes. As pivotal cellular structures within the central nervous system, ion channels play critical roles in regulating neuronal excitability, synaptic transmission, and neurotransmitter release. Extensive research has revealed significant alterations in the expression and function of ion channels in AD, implicating an important role of ion channels in the pathogenesis of abnormal Aβ deposition, neuroinflammation, oxidative stress, and disruptions in calcium homeostasis and neural network functionality. This review systematically summarizes the crucial roles and underlying mechanisms of ion channels in the onset and progression of AD, highlighting how these channel abnormalities contribute to AD pathophysiology. We also discuss the therapeutic potential of ion channel modulation in AD treatment, emphasizing the importance of addressing multifactorial nature and heterogeneity of AD. The development of multi-target drugs and precision therapies is proposed as a future direction of scientific research.

OBJECTIVE: To observe the clinical efficacy of 3D printing spinal external fixator combined with McKenzie therapy for patients with lumbar dics herniation (LDH). METHODS: Sixty patients with LDH between January 2022 and January 2023 were enrolled. Among them, 30 patients were given McKinsey training. According to different treatment methods, all patients were divided into McKenzie group and McKenzie + 3D printing group, 30 patients in each group. The McKenzie group provided McKenzie therapy. The McKenzie + 3D printing group were treated with 3D printing spinal external fixation brace on the basis of McKenzie therapy. Patients in both groups were between 25 and 60 years of age and had their first illness. In the McKenzie group, there were 19 males and 11 females, with an average age of (48.57±5.86) years old, and the disease duration was (7.03 ±2.39) months. The McKenzie + 3D printing group, there were 21 males and 9 females, with an average age of (48.80±5.92) years old, and the disease duration was(7.30±2.56) months. Pain was evaluated using the visual analogue scale (VAS), and lumbar spine function was assessed using the Oswestry disability index (ODI) and the Japanese Orthopaedic Association (JOA) score. VAS, ODI and JOA scores were compared between two groups before treatment and at 1, 3, 6, 9 and 12 months after treatment. RESULTS: All patients were followed up for 12 months. The VAS for the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(6.533±0.860), (5.133±1.008), (3.933±0.868), (2.900±0.759), (2.067±0.640), (1.433±0.504), respectively. In the McKenzie group, the corresponding scores were (6.467±0.860), (5.067±1.048), (4.600±0.968), (3.533±1.008), (2.567±0.728), (1.967±0.809), respectively. The ODI of the McKenzie group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were (41.033±6.810)%, (37.933±6.209)%, (35.467±6.962)%, (27.567±10.081)%, (20.800±7.531)%, (13.533±5.158)%, respectively. For the McKenzie combined with 3D printing group, the corresponding ODI were(38.033±5.605)%, (33.000±6.192)%, (28.767±7.045)%, (22.200±5.517)%, (17.700±4.836)%, (11.900±2.771)%, respectively. The JOA scores of the McKenzie combined with 3D printing group before treatment and at 1, 3, 6, 9, and 12 months post-treatment were(8.900±2.074), (13.133±2.330), (15.700±3.583), (20.400±3.480), (22.267±3.084), (24.833±2.640), respectively. In the McKenzie group, the corresponding scores were(9.200±2.091), (12.267±2.406), (15.333±3.198), (18.467±2.240), (20.133±2.751), (22.467±2.849), respectively. Before the initiation of treatment, no statistically significant differences were observed in the VAS, ODI, and JOA scores between two groups (P>0.05). At 3, 6, 9, and 12 months post-treatment, the VAS in the McKenzie combined with 3D printing group was significantly lower than that in the McKenzie group, and the difference was statistically significant (P<0.05). The comparison of ODI between two groups at 1, 3, 6, 9, and 12 months post-treatment revealed statistically significant differences (P<0.05). At 6, 9, and 12 months post-treatment, the JOA score in the McKenzie combined with 3D printing group was significantly higher than that in the McKenzie-only group, and the difference was statistically significant (P<0.05). CONCLUSION The combination of 3D printed functional spinal external fixation brace with McKenzie therapy can significantly improve and maintain lumbar function in patients with LDH.

OBJECTIVE: This study aimed to reexplore minimum iodine excretion and to build a dietary iodine recommendation for Chinese adults using the obligatory iodine loss hypothesis. METHODS: Data from 171 Chinese adults (19-21 years old) were collected and analyzed based on three balance studies in Shenzhen, Yinchuan, and Changzhi. The single exponential equation was accordingly used to simulate the trajectory of 24 h urinary iodine excretion as the low iodine experimental diets offered (iodine intake: 11-26 μg/day) and to further deduce the dietary reference intakes (DRIs) for iodine, including estimated average requirement (EAR) and recommended nutrient intake (RNI). RESULTS: The minimum iodine excretion was estimated as 57, 58, and 51 μg/day in three balance studies, respectively. Moreover, it was further suggested as 57, 58, and 51 μg/day for iodine EAR, and 80, 81, and 71 μg/day for iodine RNI or expressed as 1.42, 1.41, and 1.20 μg/(day·kg) of body weight. CONCLUSION The iodine DRIs for Chinese adults were established based on the obligatory iodine loss hypothesis, which provides scientific support for the amendment of nutrient requirements.

OBJECTIVE: To investigate hypertension (HTN) trends, key risk factors, and gender disparities in rural China, and to propose targeted strategies for improving HTN control in resource-limited settings. METHODS: This longitudinal study used data from the Henan Rural Cohort Study, including baseline (2015-2017; n = 39,224) and follow-up (2018-2022; n = 28,621) participants. HTN was defined as systolic/diastolic blood pressure ≥ 140/90 mmHg, self-reported diagnosis, or use of antihypertensive medication. Severity was classified using a 7-tier blood pressure (BP) staging system (optimal, normal, high normal, and HTN stages 1-4). A generalized linear mixed-effects model (GLMM) identified associated risk factors. RESULTS: HTN prevalence increased modestly from 32.7% (95% CI: 32.2-33.2) to 33.9% (95% CI: 33.3%-34.4%). Awareness and treatment improved from 20.1% to 25.3%, and from 18.8% to 24.4%, respectively, but control rates remained low (6.2% to 12.3%). After adjustment, women had a 1.53-fold higher HTN risk than men ( OR = 1.53, 95% CI: 1.43-1.63), revealing gender-specific trends. Key risk factors included alcohol use ( OR = 1.37, 95% CI: 1.27-1.47) and overweight status ( OR = 1.76, 95% CI: 1.66-1.86). BP staging showed an increase in optimal BP (42.3% to 45.8%), but stagnant management of advanced HTN stages. CONCLUSION Hypertension in rural China is shaped by behavioral risk factors and healthcare access gaps. Gender-sensitive, community-based interventions, including task-shifting models, are necessary to mitigate the growing burden of hypertension.

This review delves into the pivotal role of necrotic apoptosis in Alzheimer's disease(AD),with a focus on treatment strategies,drug development,prospects,and challenges,highlighting its significance in the progression of the disease.Firstly,necrotic apoptosis plays a crucial role in the pathogenesis of AD,particularly in association with the abnormal metabolism of β-amyloid(Aβ)and Tau proteins.The primary focus of drug design is to regulate the metabolism pathways of these two proteins to slow down or inhibit the progression of necrotic apoptosis.Secondly,the progress in drug development further emphasizes the importance of necrotic apoptosis in treating AD.Current research mainly focuses on drugs that affect the metabolism of Aβ and Tau proteins,such as lecanemab.Still,inconsistent result underscore the necessity for a more comprehensive understanding of the molecular mechanisms of necrotic apoptosis.Finally,the prospects and challenges of necrotic apoptosis research in AD are thoroughly discussed.A deeper understanding of necrotic apoptosis contributes to a better comprehension of the pathological mechanisms of AD but also may reveal new therapeutic targets.However,challenges such as multifactorial influences and the selection of treatment timing necessitate further in-depth research in the future.In conclusion,this review advocates for future research to deepen the understanding of the molecular mechanisms of necrotic apoptosis,enhance research on treatment strategies,gain a deeper understanding of its cross-regulation with other cell death pathways,and promote collaboration between basic research and clinical practice to advance the comprehensive understanding and treatment of Alzheimer's disease and necrotic apoptosis.

Objective:To explore the effects of graft recipient weight ratio (GRWR) on the early prognosis (within 1 year after operation) of recipients of different ages after split liver transplantation (SLT) in children.Methods:From April 2015 to December 2022, the relevant clinical data were retrospectively reviewed for 188 children aged under 12 years undergoing initial SLT. Based upon operative age, they were assigned into groups of L (age≤18 months, 123 cases) and H (18 months< age≤12 years, 65 cases). Draw receiver operating characteristic (ROC) curves for predicting survival rates in H and L groups using GRWR and determine the cut-off value, and subgroup dassification was based the value. Compare the general condition, intraoperative condition, postoperative condition, and major complications of recipients. Follow-ups were conducted until 12 months post-SLT, death or retransplantation within 12months post-SLT. Kaplan-Meier survival rate analysis was utilized for comparing early postoperative survival rate of recipient/graft. The incidence of major early postoperative complications was examined by χ2 test or Fisher exact probability method. Results:The survival rate of recipients at Month 12 post-SLT was 92.6% (174/188), and graft survival rate was 91.0% (171/188). The survival rate of recipients in group L at Month 12 post-SLT was 94.3% (116/123), and graft survival rate was 92.7% (114/123). The GRWR value determined of 3.1 %. According to the level of GRWR, group L was divided into groups of L-L (GRWR≤3.1%, 36 cases) and L-H (GRWR>3.1%, 87 cases) while group H groups of H-L (GRWR≤3.1%, 55 cases) and H-H (GRWR>3.1%, 10 cases). The survival rates of recipients in groups L-L/L-H were 88.9% (32/36) and 96.6% (84/87) at Month 12 post-SLT. Inter-group difference was not statistically significant ( P=0.077). Graft survival rates were 83.3% (30/36) and 96.6% (84/87 ). Inter-group difference was statistically significant ( P=0.007). The intraoperative cold ischemia time were 479.0 (194.0, 593.0) min and 204.0 (122.0, 495.0) min in groups L-L/L-H. Inter-group difference was statistically significant ( P=0.002 ). The incidence of hepatic artery thrombosis were 13.9 % (5/36) and 2.3 % (2/87) in groups L-L/L-H. Inter-group difference was statistically significant ( P=0.036). The survival rate of recipients in group H at Month 12 post-SLT was 89.2% (58/65), and graft survival rate was 87.7% (57/65). No significant inter-group difference existed during surgery ( P>0.05 ). The survival rates of recipients in group H-L/H-H at Month 12 post-SLT were 92.7 % (51 /55) and 70.0 % (7/10 ). Inter-group difference was statistically significant ( P=0.019). Graft survival rates were 90.9% (50/55) and 70.0% (7/10). Inter-group difference was statistically significant ( P=0.036). No significant inter-group difference existed in the incidence of complications ( P>0.05) . Conclusion:During pediatric SLT, recipients of different ages have different requirements for GRWR. GRWR≤3.1 % implies poor early prognosis of recipients aged ≤18 months and GRWR>3.1% is associated with poor early prognosis of recipients aged between 18 months and 12 years.

Objective:To explore the risk factors and treatments of portal vein thrombosis (PVT) in children after pediatric living donor liver transplantation (pLDLT) .Method:From January 2014 to December 2021, the relevant clinical data were retrospectively reviewed for 975 LDLT children at Department of Pediatric Organ Transplantation of Tianjin First Central Hospital. Based upon the postoperative occurrence of PVT, they were assigned into two groups of PVT (19 cases) and non-PVT (956 cases). Univariate and multivariate analyses were performed for screening the risk factors of PVT post-LDLT and discussing the managements and prognoses of PVT.Result:Among them, overall incidence of PVT post-LDLT was 1.9% (19/975), and median time for an initial occurrence of PVT 8 (1-495) day. Single-factor analysis indicated that donor height ( P=0.014), operative duration ( P=0.002) and vascular interposition ( P=0.001) were correlated with the occurrence of postoperative PVT post-pLDLT. Multifactorial analysis revealed that operative duration ( P=0.008) and vascular interposition ( P<0.01) were independent risk factors for PVT post-pLDLT. For 19 cases of postoperative PVT, the measures included surgical thrombectomy (8 cases), urokinase thrombolysis plus warfarin anticoagulation (3 cases), interventional treatment (3 cases), warfarin anticoagulation (4 cases) and retransplantation (1 cases). After treatment, the outcomes were a disappearance of PVT (15 cases), symptomatic improvement (2 cases) and unrelated mortality (2 cases) . Conclusion:During pLDLT, intraoperative placement of blood vessels and operative duration are independent risk factors for the occurrence of PVT. Timely standardized treatment may achieve satisfactory therapeutic outcomes.
