ObjectiveMitochondria are not only the central organelles responsible for cellular energy metabolism but also play essential roles in regulating cell cycle progression and cytoskeletal dynamics. In recent years, accumulating evidence has demonstrated that mitochondrial homeostasis is closely associated with mitotic progression and cytokinesis. Schizosaccharomyces pombe serves as a classical and well-established model organism. Because its cell cycle regulatory mechanisms are highly conserved throughout evolution, its genetic background is clearly defined, and experimental manipulation is efficient and convenient, it has been extensively applied in studies of cell growth, division, and reproductive mechanisms. The SPBC1604.04 gene encodes a previously uncharacterized mitochondrial carrier protein in Schizosaccharomyces pombe. This gene is located on chromosome II and spans 1 018 base pairs in length. It encodes a protein consisting of 238 amino acids with a predicted molecular mass of approximately 31.03 ku. Bioinformatic analysis predicts that this protein is responsible for the transport of thiamine pyrophosphate (TPP) into mitochondria. However, the effects of SPBC1604.04 gene deletion on mitotic cell dynamics under different temperature conditions have not been fully elucidated. MethodsThe SPBC1604.04 deletion strain of Schizosaccharomyces pombe was used as the experimental model. Fluorescent protein markers were constructed in the deletion background to label mitochondria, microtubules, actin, myosin, the nuclear envelope, and chromosomes. Live-cell imaging was performed using a TCS-SP8 laser scanning confocal microscope under normal temperature conditions (25℃) and heat stress conditions (37℃). Time-lapse microscopy was applied to dynamically monitor mitochondrial morphology and distribution, spindle assembly and elongation, chromosome segregation, as well as the formation and constriction of the actomyosin ring during cytokinesis. ImageJ software was used for quantitative measurements, including microtubule length during mitosis, spindle length at different mitotic stages, mitochondrial fluorescence intensity as an indicator of mitochondrial content, actomyosin ring length, nuclear envelope area, and chromosome segregation timing. Statistical analyses were conducted to compare phenotypic differences between the wild-type and SPBC1604.04 deletion strains at both temperature conditions. Through these analyses, we systematically investigated the impact of SPBC1604.04 deletion on mitotic cell dynamics in fission yeast under both normal physiological conditions and temperature stress. ResultsAt 25℃, compared with wild-type cells, the SPBC1604.04Δ strain exhibited a pronounced tendency toward mitochondrial fragmentation, accompanied by abnormal mitochondrial content and a significant reduction in mitochondrial fluorescence intensity. These observations suggest impaired mitochondrial homeostasis under normal growth conditions. In addition, the constriction time of actomyosin ring during cytokinesis was markedly prolonged, indicating that deletion of SPBC1604.04 affects the dynamics of the contractile machinery. However, no obvious defects were observed in spindle assembly, spindle elongation, or chromosome segregation. Under heat stress at 37℃, mitochondrial morphology in the SPBC1604.04Δ strain showed a tendency to recover toward a continuous tubular network structure. Mitochondrial content was restored, fluorescence intensity increased, and the constriction time of the actomyosin ring returned to levels comparable to those of wild-type cells. These results indicate that the mitotic defects observed at normal temperature are partially or fully alleviated under heat stress conditions. ConclusionThis study demonstrates that deletion of the SPBC1604.04 gene leads to abnormal mitochondrial content in Schizosaccharomyces pombe. The mitochondrial carrier protein SPBC1604.04 participates in regulating actomyosin ring constriction during mitosis but does not appear to be directly involved in the regulation of spindle dynamics or chromosome segregation. Our findings provide key experimental evidence for understanding the functional link between the SPBC1604.04 gene, mitochondrial homeostasis, and mitotic regulation.

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

Inflammatory bowel disease (IBD) is characterized by chronic relapsing intestinal inflammation and encompasses ulcerative colitis (UC) and Crohn's disease (CD). IBD has emerged as a global healthcare problem. Clinically efficacious therapeutic agents are deficient. This study concentrates on models of ulcerative colitis with the objective of discovering novel therapeutic strategies. Previous investigations have established that schisandrin A demonstrates anti-inflammatory effects in vitro, concurrently enhancing the transcriptional activity of farnesoid X receptor (FXR). FXR inversely modulates the transcriptional activity of NF-κB, which has an important role in regulating inflammatory responses. Consequently, the current study was to explore the safeguarding influence of schisandrin A on ulcerative colitis and delineate the mechanism by which it regulates this effect through the FXR signaling pathway. The effect of schisandrin A on the mRNA levels of inflammatory factors was evaluated in RAW264.7 cells. The dual luciferase reporter gene assay was used to verify the relationship between schisandrin A and FXR targeting. The animal experiments were performed in accordance with the regulations of the Animal Ethics Committee of Shanghai University of Traditional Chinese Medicine (approval No. PZSHUTCM2304250005). Acute ulcerative colitis was induced in wild-type or FXR knockout C57BL/6 mice by drinking 3% dextran sodium sulfate (DSS) for 7 days, and schisandrin A was administered via gavage for a continuous treatment period of 7 days. The body weight and faecal were monitored daily. The mRNA levels of inflammatory factors in colon tissue and FXR target genes were measured by RT-qPCR. The findings revealed that schisandrin A, in vitro, impeded the lipopolysaccharide (LPS)-induced elevation in mRNA levels of inflammatory factors and schisandrin A could augment transcriptional activity of FXR. In wild-type mice, schisandrin A significantly improved weight loss, colon shortening, loose stools and blood in stools in mice with acute ulcerative colitis, and schisandrin A significantly reduced the expression of pro-inflammatory factors genes and significantly increased the expression of FXR target genes in colon tissues. In FXR knockout mice, the administration of schisandrin A failed to yield ameliorative effect on acute ulcerative colitis in mice. In conclusion, schisandrin A can reduce intestinal inflammation through the FXR signaling pathway to alleviate acute ulcerative colitis in mice. Implications arise that Schisandra lignans could serve as lead compounds for drug development aimed at inflammatory bowel disease.

Objective To explore whether dexmedetomidine(DEX)can alleviate exertional heatstroke(EHS)-induced rhabdomyolysis(RM)in rats by activating adrenergic α2 receptors,and to explore its potential mechanism based on the reactive oxygen species(ROS)/NOD-like receptor protein 3(NLRP3)/interleukin-1β(IL-1β)pathway.Methods Thirty-six male Sprague-Dawley(SD)rats,after a 7-day acclimatization training,were randomly divided into six groups:control group(CN group),EHS group,low-dose DEX group(EHS+low DEX group),high-dose DEX group(EHS+high DEX group),DEX combined with yohimbine(YOH)group(EHS+high DEX+YOH group),and YOH group(EHS+YOH),with six rats in each group.Before modeling,EHS+high DEX+YOH group and EHS+YOH group were intraperitoneally injected with YOH at 1 mg/kg,while the other four groups were injected intraperitoneally with an equal dose of physiological saline(0.9%NS).During modeling,except for CN group,the other 5 groups of rats were subjected to heat exercise in a high-temperature and high-humidity chamber to construct an EHS rat model.After successful modeling,EHS+low DEX group was intraperitoneally injected with DEX at 10 μg/kg,EHS+high DEX group and EHS+high DEX+YOH group were intraperitoneally injected with DEX at 30 μg/kg,and CN group,EHS group and DEX+YOH group were intraperitoneally injected with equal doses of saline.After 6 h of observation,all rats were anesthetized,and their blood from the abdominal aorta and gastrocnemius muscle tissue were taken.Enzyme-linked immunosorbent assay(ELISA)was used to detect the expression levels of serum tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),IL-1β and myoglobin(MB)in rats;biochemical assay kit was used to measure the level of creatine kinase(CK)in rat serum;HE staining was used to observe pathological changes in rat gastrocnemius muscle tissues;transmission electron microscopy was used to observe ultrastructural changes in gastrocnemius muscle;2′,7′-dichlorofluorescent yellow diacetate(DCFH-DA)fluorescent probe was used to detect the level of reactive oxygen species(ROS);and Western blotting was performed to detect the expression levels of NOD-like receptors 3(NLRP3),aspartic protease-1(caspase-1)and adrenergic α2A receptor(ADRA2A).Results Compared with CN group,the levels of serum IL-6,IL-1β,TNF-α,CK and MB in EHS group rats were significantly elevated(P<0.01).HE staining results revealed that the gastrocnemius muscle tissues of rats in EHS group had these pathological manifestations such as disarray of muscle fibrous structure,hemorrhage,edema,and infiltration of inflammatory cells.Transmission electron microscopy results showed that the ultrastructure of the gastrocnemius muscle in EHS group exhibited myofibroblasts with swelling and enlarging in size,cytoplasmic vacuolization,and mitochondria with obvious swelling,degranulation,and disappearance of double cristae.Compared with CN group,the expression levels of ROS,NLRP3,and caspase-1 in gastrocnemius of rats in EHS group significantly increased(P<0.01);Compared with EHS group,the levels of TNF-α,IL-6,IL-1β,CK,MB and the expression levels of ROS,NLRP3,caspase-1 in gastrocnemius tissue of rats in EHS+low DEX group and EHS+high DEX group decreased in a dose-dependent manner(P<0.05),and the pathological damage observed with HE staining and transmission electron microscopy was alleviated by DEX.After YOH pretreatment,compared with the EHS+high DEX group,the serum levels of TNF-α,IL-6,IL-1β,CK,MB and ROS,NLRP3 and caspase-1 in the gastrocnemius muscle tissue of rats in EHS+high DEX+YOH group relatively increased(P<0.05),and the pathological damage observed with HE staining and transmission electron microscopy was exacerbated.The expression of ADRA2A in gastrocnemius muscle of EHS group significantly decreased compared with CN group(P<0.01),and the expression of ADRA2A in muscle of rats in DES+low DEX group and EHS+high DEX group was higher than that in EHS group(P<0.05).Conclusions DEX can alleviate EHS-induced RM by activating ADRA2A,potentially through inhibiting the ROS-dependent NLRP3/IL-1β inflammatory pathway.
