ObjectiveTaking the cuproptosis/oxidative stress pathway as the entry point， this study investigated the effect and mechanism of Liangyi Paste on hepatic lipid deposition in naturally aged mice fed with a high-fat diet. MethodsAfter adaptive feeding， 80 ten-week-old male C57BL/6 mice were used. Thirty of them were randomly divided into three groups （10 mice per group）： The 12-month-old control group （12MCON）， the 15-month-old control group （15MCON）， and the 15-month-old group with a high-fat diet （15MHFD）. The 12MCON and 15MCON groups were continuously fed a standard diet， while the 15MHFD group started receiving a high-fat diet at 12 months of age. Tissue samples were collected at the corresponding time points for each group. The remaining 50 mice were randomly divided into five groups （10 mice per group）： the 20-month-old control group （20MCON）， the model group， and the low-， medium-， and high-dose Liangyi Paste groups （2.91 ， 5.82 ， 11.64 g·kg^-1·d^-1， respectively）. The 20MCON group was continuously fed a standard diet， while the other groups started receiving a high-fat diet at 15 months of age. At 18 months of age， the Liangyi Paste groups were administered the corresponding doses of Liangyi Paste by gavage， while the 20MCON and model groups were given an equal volume of saline by gavage. After 8 weeks of continuous gavage （when the mice reached 20 months of age）， tissue samples were collected. Hepatic TG levels were measured using assay kits； liver histology and lipid deposition were observed via hematoxylin-eosin （HE） and oil red O staining； reactive oxygen species （ROS） were detected by enzyme-linked immunosorbent assay （ELISA）； Cu²⁺， superoxide dismutase （SOD）， and malondialdehyde （MDA） levels were measured by colorimetry； mRNA and protein expression of genes related to cuproptosis and oxidative stress pathways were analyzed by Real-time polymerase chain reaction（Real-time PCR） and Wes automated protein expression system. ResultsCompared with 12MCON， the 15MCON group showed significantly increased hepatic TG， Cu²⁺， ROS， and MDA levels （P<0.01）， decreased SOD （P<0.01）， hepatocyte swelling， and disordered arrangement. The mRNA and protein levels of ferredoxin 1 （FDX1）， dihydrolipoamide S-acetyltransferase （DLAT）， heat shock protein 70 （HSP70）， dihydrolipoamide dehydrogenase （DLD）， pyruvate dehydrogenase E1 subunit-β （PDHB）， nuclear factor erythroid 2-related factor 2 （Nrf2）， and peroxisome proliferator-activated receptor γ （PPARγ） were significantly elevated （P<0.05， P<0.01）. Compared with 15MCON group， the 15MHFD and 20MCON groups exhibited further increases in TG， Cu²⁺， ROS， and MDA （P<0.01）， reduced SOD （P<0.01）， and aggravated hepatocyte swelling and disorder. There were increased lipid droplets with mild vacuolization in the 15MHFD group， and no significant lipid deposition was observed in the 20MCON group. FDX1， DLAT， HSP70， DLD， PDHB， Nrf2， and PPARγ mRNA and protein levels were significantly increased （P<0.05， P<0.01）. Compared with 20MCON group， the model group demonstrated markedly elevated TG， Cu²⁺， ROS， and MDA （P<0.01）， reduced SOD （P<0.01）， severe hepatic steatosis， and upregulated expression of FDX1， DLAT， HSP70， DLD， PDHB， Nrf2， and PPARγ mRNA and proteins （P<0.05， P<0.01）. All abnormalities were significantly reversed after Liangyi Paste treatment. ConclusionLiangyi paste can ameliorate hepatic lipid deposition in naturally aged mice with a high-fat diet by modulating the cuproptosis/oxidative stress pathway.

Objective: : Kinesin family member C1 (KIFC1), a non-essential kinesin-like motor protein, has been found to serve a crucial role in supernumerary centrosome clustering and the progression of several human cancer types. However, the role of KIFC1 in glioma has been rarely reported. Thus, the present study aimed to investigate the role of KIFC1 in glioma progression. Methods: : Online bioinformatics analysis was performed to determine the association between KIFC1 expression and clinical outcomes in glioma. Immunohistochemical staining was conducted to analyze the expression levels of KIFC1 in glioma and normal brain tissues. Furthermore, KIFC1 expression was knocked in the glioma cell lines, U251 and U87MG, and the functional roles of KIFC1 in cell proliferation, invasion and migration were analyzed using cell multiplication, wound healing and Transwell invasion assays, respectively. The autophagic flux and expression levels matrix metalloproteinase-2 (MMP2) were also determined using imaging flow cytometry, western blotting and a gelation zymography assay. Results: : The results revealed that KIFC1 expression levels were significantly upregulated in glioma tissues compared with normal brain tissues, and the expression levels were positively associated with tumor grade. Patients with glioma with low KIFC1 expression levels had a more favorable prognosis compared with patients with high KIFC1 expression levels. In vitro, KIFC1 knockdown not only inhibited the proliferation, migration and invasion of glioma cells, but also increased the autophagic flux and downregulated the expression levels of MMP2. Conclusion : Upregulation of KIFC1 expression may promote glioma progression and KIFC1 may serve as a potential prognostic biomarker and possible therapeutic target for glioma.

Objective     To compare the clinical effects of coronary artery bypass grafting (CABG) via the left anterior small thoracotomy (LAST) versus lower-end sternal splitting (LESS) approach in the treatment of coronary heart disease. Methods     The patients who underwent LAST CABG in Tianjin Chest Hospital from October 2015 to December 2020 were allocated to an observation group (LAST group), and the patients who underwent LESS CABG at the same period were allocated to a LESS group. Propensity score matching method was applied with a ratio of 1∶1. The baseline data, perioperative data and grafts data were compared between the two groups after matching. Results     Before matching, there were 110 patients in the LAST group, and 206 patients in the LESS group. After matching, there were 110 patients in each group. In the LAST group, there were 83 males and 27 females with an average age of 60.6±8.3 years. In the LESS group, there were 80 males and 30 females with an average age of 61.0±9.6 years. There was no statistical difference in baseline data between the two groups after matching (P>0.05). The hospital stay time (t=2.255, P=0.025) and ventilator using time (t=−2.229, P=0.027) in the LAST group were significantly shorter than those in the LESS group. There were no statistical differences between the two groups in the postoperative hospital stay time, ICU stay time, postoperative left ventricular ejection fraction, postoperative left ventricular end-diastolic diameter, average number of grafts, secondary intubation, secondary thoracotomy, postoperative wound infection, sternal complications, postoperative atrial fibrillation, postoperative pulmonary infection or main adverse cardiovascular and cerebrovascular events (P>0.05). There was no statistical difference in the distribution of target vessels in the anterior descending branch, diagonal branch or posterior descending branch between the two groups (P>0.05). The grafts of the LAST group were significantly more than those of the LESS group in the area of obtuse marginal branch and posterior ventricular branch, and the grafts of the LESS group were significantly more than those of the LAST group in the area of right coronary artery (P<0.05). Post-operative computerized tomography angiography indicated that 1 patient in the LAST group had obtuse marginal branch vein bridge vessel occlusion, and the bridge vessels in the other patients were unobstructed. Conclusion     Minimally invasive CABG via both LAST and LESS approaches is safe and effective. LAST approach can achieve complete revascularization for multi-vessel lesions, and it is safe and reliable, with the advantages of less trauma and aesthetic appearance. However, it requires a certain learning curve of surgical techniques and certain surgical indications.
