Based on the regulation of mitochondrial fatty acid β-oxidation through the PGC1α/PPARα/CPT1A pathway, this study investigated the effect of Jianpi Qinghua Formula on the mitochondrial fatty acid β-oxidation pathway in the livers of mice with metabolic-associated fatty liver disease(MAFLD) induced by a high-fat diet. MAFLD mice were fed a high-fat diet to establish the model, and after successful modeling, the mice were divided into the model group, the Jianpi Qinghua Formula group, and the metformin group, with an additional control group. Each group was treated with the corresponding drug or an equivalent volume of saline via gavage. Body mass and food intake were measured regularly during the experiment. At the end of the experiment, blood lipid levels and liver function-related indices were measured, liver pathological changes were observed, and protein expression levels of PGC1α, PPARα, PPARγ, and CPT1A were detected by Western blot. The results showed that, with no difference in food intake, compared to the model group, the body mass of the Jianpi Qinghua Formula group and the metformin group was reduced, liver weight and liver index decreased, and levels of cholesterol, triglycerides, and low-density lipoprotein cholesterol(LDL-C) were lowered. Additionally, a decrease in alanine aminotransferase(ALT) and aspartate aminotransferase(AST) was observed. Hematoxylin and eosin(HE) staining revealed reduced pathological damage to hepatocytes, while oil red O staining showed improvement in fatty infiltration. The liver disease activity score decreased, and transmission electron microscopy revealed improvement in mitochondrial swelling and restoration of internal cristae. Western blot analysis indicated that Jianpi Qinghua Formula significantly increased the expression of PGC1α, PPARα, and CPT1A proteins in the liver and reduced the expression of PPARγ. These results suggest that the Jianpi Qinghua Formula improves mitochondrial function, promotes fatty acid oxidation, and alleviates the pathological changes of MAFLD. In conclusion, Jianpi Qinghua Formula can improve MAFLD by mediating mitochondrial fatty acid β-oxidation through the PGC1α/PPARα/CPT1A pathway.

Iodine speciations in aquatic environments are affected by dissolved oxygen,redox potential,microbial activity,organic matter decomposition,light reaction,etc.Accurate quantification of iodine speciation can not only help to understand the geochemical cycle of iodine,but also help to trace and study environmental processes.Based on the combination of ion chromatography(IC)and inductively coupled plasma mass spectrometry(ICP-MS),a rapid and sensitive method was established for determining the speciations of iodine in environmental water samples including seawater,river water,lake water,rainwater,groundwater,etc.The results presented here showed that IO3?and I?in seawater were quickly separated and measured within 120 s when using guard column AG22 and 8 mmol/L(NH4)2CO3 as the mobile phase.While for lake water,river water and precipitation samples with high soluble organically bond iodine(SOI),an AS22 separation column(250 mm×4 mm)connected with a guard column and using 50 mmol/L(NH4)2CO3 as mobile phase could effectively separate unknown SOI from IO3? to achieve accurate quantification of IO3?.For accurate correction of iodine measurement signal fluctuations,133Cs was directly added to the(NH4)2CO3 mobile phase as an internal standard.The SOI content was calculated by the total iodine concentrations minus the sum of IO3?and I?.The precision of the established iodine speciation analytical method was better than 3.5%,and the standard addition experiment showed that the analytical method was accurate.When the injection volume was 25 μL,the detection limits were 0.011?0.025 μg/L for IO3? and 0.023?0.031 μg/L for I?,respectively.The method was successfully used to analyze IO3?,SOI and I? in environmental water samples,such as seawater,river water,rainwater and groundwater.

Objective To investigate the role and underlying mechanism of C1q-like protein 4 (C1ql4) in regulating the characteristics of breast cancer stem cells. Methods qRT-PCR was used to detect the expression of C1ql4 in breast cancer and normal breast epithelial cell lines, as well as to verify the transfection efficiency of C1ql4. Western blot analysis was employed to examine the phosphorylation levels of AKT, IKK, and IκB in different groups. An AKT activator was added to MDA-MB-231 cells with C1ql4 knockdown, whereas inhibitors targeting AKT, IKK, IκB, and NF-κB nuclear translocation were separately introduced to C1ql4-overexpressing MCF-7 cells. The nuclear translocation of NF-κB, expression levels of the target genes TNF-α and IL-1β, formation ability of tumorspheres, and proportion of CD44⁺/CD24^−/low stem-like subgroups were analyzed. Results C1ql4 expression in breast cancer cell lines was significantly upregulated compared with that in normal breast epithelial cells. Western blot analysis showed that p-AKT/AKT, p-IKK/IKK, and p-IκB/IκB ratios markedly reduced in C1ql4-knockdown MDA-MB-231 cells (all P<0.05) but significantly increased in C1ql4-overexpressing MCF-7 cells (all P<0.05). Rescue experiments demonstrated that the addition of an AKT activator to C1ql4-knockdown MDA-MB-231 cells resulted in the enhanced nuclear translocation of NF-κB, the increased nuclear/cytoplasmic NF-κB ratios, the elevated TNF-α and IL-1β expression levels, and significant recovery of tumorsphere formation ability and the proportion of CD44⁺/CD24^−/low stem-like subpopulations (all P<0.05). Conversely, in C1ql4-overexpressing MCF-7 cells, treatment with AKT, IKK, IκB, or NF-κB nuclear translocation inhibitors led to a reduction in NF-κB nuclear translocation, decreased nuclear/cytoplasmic NF-κB ratios, and declines in TNF-α and IL-1β expression levels, tumorsphere formation ability, and the CD44⁺/CD24^−/low subpopulation (all P<0.05). Conclusion C1ql4 promotes the translocation of NF-κB from the cytoplasm to the nucleus through the PI3K/AKT/NF-κB signaling pathway and enhances the expression of stemness in breast cancer cells.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Background and Aims:CNLC stage IIIb hepatocellular carcinoma(HCC)is often accompanied by extrahepatic metastases and carries a poor prognosis.The optimal treatment strategy for these patients remains controversial,and the role of local therapy lacks robust evidence.This study aimed to compare overall survival(OS)between patients receiving combined local and systemic therapy versus systemic therapy alone,and to assess the prognostic impact of oligometastatic status and the cumulative duration of no evidence of disease(NED).Methods:A retrospective analysis was conducted on 76 CNLC stage IIIb HCC patients treated at Xiangya Hospital from January 2017 to December 2023.Forty patients received systemic therapy plus local therapy(local therapy group),and 36 received systemic therapy alone(no local therapy group).OS was compared between the two groups.Subgroup analyses were performed for oligometastatic and non-oligometastatic patients to evaluate the benefit of local therapy.In the local therapy group,the correlation between cumulative NED duration and OS was also examined.Results:The 1-,2-,3-,and 5-year OS rates were 89.0%vs.66.7%,64.3%vs.25.6%,35.3%vs.8.7%,and 8.3%vs.0.0%for the local therapy and no local therapy groups,respectively,with a statistically significant difference(P=0.003).Among oligometastatic patients,the local therapy group had significantly better OS than the no local therapy group(P=0.008),whereas no significant difference was observed in non-oligometastatic patients(P>0.05).Multivariate analysis identified oligometastases as an independent prognostic factor(HR=2.213,P=0.045).In the local therapy group,cumulative NED duration was strongly correlated with OS(r=0.851,P<0.001).Local therapy was well tolerated,with no treatment-related deaths observed.Conclusion:For CNLC stage IIIb HCC patients with well-controlled intrahepatic disease,local therapy can significantly prolong survival,particularly in those with oligometastases.Achieving and maintaining NED may represent an important therapeutic goal in this patient population.

With the establishment of bio-psycho-social medical model,both social and psychological factors play an important role in the occurrence,development and treatment of diseases.Hypertension is a common chronic multiple disease in China,and patients are often complicated with depression and other e-motional disorders.The interaction between hypertension and depression significantly increases the risk of poor prognosis.Current studies have shown a bidirectional promoting relationship between hypertension and depression,and they have some com-mon pathogenesis.However,the specific mechanism of their co-morbidity has not been fully elucidated.Renin-angiotensin sys-tem(RAS)plays an important role in the regulation of hyperten-sion and depression and other emotions.It is composed of two antagonistic pathways.The balance is maintained by angioten-sin-converting enzyme 2(ACE2).Therefore,this article reviews the relationship and mechanism of RAS in hypertension,depres-sion and comorbid states,in order to provide new treatment ide-as for hypertension and depression.
