A retrospective analysis was conducted on data from five patients comprehensively diagnosed with emphysematous osteomyelitis (EO) based on clinical, imaging, microbiological culture, and surgical findings at Hebei Medical University Third Hospital from December 2020 to May 2024. Among these five cases, there were three males and two females, aged between 11 and 69 years. Three patients had infection risk factors (two with diabetes and one with anemia), while two had no documented risk factors in their medical history. All patients presented with fever, localized pain at the infection site, and elevated inflammatory markers. Site of incidence: EO affected the lumbar spine in three cases, the ilium in one case, and the femur in one case. Pathogenic microorganisms: The causative agents included Klebsiella pneumoniae (two cases), Escherichia coli (one case), Burkholderia cepacia (one case), and a mixed infection of Staphylococcus aureus and Acinetobacter baumannii (one case). Imaging findings: Among the three patients who underwent X-ray examinations, one showed normal results, while two exhibited bone destruction. CT scans of all five cases revealed the characteristic "pumice sign" without periosteal reaction or osteosclerosis. MRI, performed on four patients, demonstrated bone destruction, swelling of surrounding soft tissues, and soft tissue abscess formation. Treatment and outcomes: Four patients underwent surgical debridement combined with perioperative antibiotic therapy. Of these, three recovered well, while one achieved good infection control but suffered severe joint destruction. One patient died after treatment was discontinued. The clinical and laboratory findings of EO resemble those of common acute osteomyelitis; however, EO has distinct imaging characteristics. Timely diagnosis, aggressive surgical debridement, and strong, targeted antibiotic therapy can result in favorable outcomes. Conversely, delayed diagnosis and treatment may lead to severe complications or death.

A wealth of prior studies has confirmed that intratumoral microbiota can survive within tumor tissue, thereby promoting or inhibiting tumor growth. With the development of high-throughput sequencing and metabolomics, increasing attention has been paid to the correlation between intratumoral microbiota and host metabolism, and their effect on tumorigenesis and progression. This review focuses on the interaction between intratumoral microbiota and tumor metabolism. It emphasizes the effects of intratumoral microbiota on tumor sugar, lipid, and amino acid metabolism and explores emerging therapeutic strategies for guiding tumor prevention and treatment by modulating tumor metabolism. Although the specific role of intratumoral microbiota in tumor metabolism remains to be further studied, a deepened understanding of the interaction between tumor-specific microbiota and tumor metabolism may provide new directions and application prospects for tumor prevention and treatment.

Acute respiratory distress syndrome (ARDS) is the leading cause of respiratory failure with high morbidity and mortality. Pulmonary surfactant (PS)-based complementary therapies have exhibited potential for ARDS healing and applied as an adjunctive therapy strategy. Coacervate (Coac) has the characteristics of softness, deformability and excellent molecular enrichment properties, and has attracted extensive attention in the biomedical field. Here PS and coacervate were combined for the potential ARDS treatment. The Coac, fabricated from polyallylamine hydrochloride (PAH) and adenosine triphosphate (ATP) by simple mixing, exhibited soft droplet property and high enrichment for dexamethasone sodium phosphate (DSP). To avoid the fusion effect of membraneless coacervate and endow it with biological functions of PS, liposomes with PS-biomimetic lipid components (PS-lipo) were further introduced to construct PS-biomimetic membranized coacervate (DSP@PS-Coac). The DSP@PS-Coac demonstrated high lung targeting effect and significant penetration efficiency after intravenous injection. Furthermore, PS-lipo replenished the endogenous PS pool and facilitated the distribution of DSP in inflammatory cells in the lung. In the ARDS mouse model, PS-Coac and DSP exerted synergetic anti-inflammatory functions, via reducing the recruitment of inflammatory neutrophils and modulating macrophages into anti-inflammatory phenotype. The overall results confirmed that DSP@PS-Coac may provide a promising delivery option for the treatment of ARDS.

Objective:To explore the efficacy and safety of vagus nerve stimulation (VNS) combined with rehabilitation training in recovery of upper limb function in patients with ischemic stroke (IS) through Meta-analysis.Methods:Randomized controlled trials on upper limb motor dysfunction in IS patients accepted VNS published in PubMed, Web of Science, Embase, CNKI, Wanfang and VIP databases, and Chinese Biomedical Literature Database were retrieved. The retrieval period was from establishment of the databases to April 2025. Quality of the trials was assessed according to Cochrane handbook for systematic reviews of interventions (version 5.1). Two researchers independently screened the literature, extracted the data and evaluated the risk of bias of the included articles; and then, Meta-analysis was conducted by RevMan 5.4 software.Results:Eleven articles of randomized controlled trails were chosen, including 495 patients. Three articles were rated as A-level in terms of quality, and 8 were rated as B-level. Overall bias risk of the included studies was low. Results of Meta-analysis showed that compared with the control group (rehabilitation training alone), the intervention group (VNS combined with rehabilitation training) had significantly improved upper limb motor function (Fugl-Meyer assessment of upper limb motor function: standardized mean difference [ SMD]=0.77, 95% CI: 0.24-1.30, P<0.001) and activities of daily living (modified Barthel index: SMD=0.86, 95% CI: 0.56-1.16, P<0.001). Meanwhile, compared with those in the control group, incidence of adverse events ( RR=1.12, 95% CI: 0.95-1.33, P=0.170) and incidence of severe adverse events ( RR=1.67, 95% CI: 0.51-5.50, P=0.400) in the intervention group did not significantly increase. Results of subgroup analysis showed that compared with that in the control group, more significantly improved upper limb motor function was noted in patients from the non-invasive VNS intervention sub-group ( SMD=1.09, 95% CI: 0.46-1.72, P<0.001), intervention sub-group with a frequency of 5 times per week ( SMD=1.73, 95% CI: 0.58-2.87, P<0.001), and intervention sub-group with a duration of 4 weeks ( SMD=1.09, 95%CI: 0.72-1.47, P<0.001). Conclusion:VNS combined with rehabilitation training has good safety and efficacy in upper limb motor dysfunction after IS.

Objective:To systematically compare the clinical effects of simultaneous zona pellucida opening and prehatching in ectodermal biopsy techniques and to provide evidence-based medical evidence for the establishment of standard blastocyst biopsy procedure.Methods:We systematically searched PubMed, Cochrane Library, Embase, Web of Science, CBM, CNKI, VIP and Wanfang Data published until August 2023. We searched the literatures for studies that compared the effects of two zona pellucida opening. Primary evaluation measures included clinical pregnancy rate and live birth rate, and secondary evaluation indicators included biopsy success rate, euploid blastocyst rate, and miscarriage rate. Meta-analysis was performed using the R4.2.2 software meta package.Results:Six studies, including 12 223 biopsy embryos and 2 374 transfer cycles were subjected to analysis. The results of meta-analysis showed that the clinical pregnancy rate ( RR=1.22, 95% CI: 1.14-1.30, P<0.01) and the live birth rate ( RR=1.22, 95% CI: 1.12-1.32, P<0.01) in the simultaneous zona pellucida opening group were significantly higher than those in the prehatching group, and there were no significant differences between the two groups in biopsy success rate ( RR=1.38, 95% CI: 0.30-6.25, P=0.68), euploid blastocyst rate ( RR=0.98, 95% CI: 0.83-1.15, P=0.81) and miscarriage rate ( RR=1.06, 95% CI: 0.77-1.47, P=0.73). Conclusion:Stimultaneous zona pellucida opening blastocyst biopsy protocol is better than prehatching in terms of clinical pregnancy rate and live birth rate. Due to the limitation of sample size and quality of included studies, more high-quality studies are needed on the effect of zona pellucida opening timing on clinical outcomes.
