Robotic surgery is known as the"third technological revolution"in the field of surgery,and is an important milestone in the development of modern surgery.However,our country's innovative surgical robot industry is still in its early stages,and it is only being utilized in certain surgical fields.To explore the effectiveness of the application of do-mestic surgical robot in oral and maxillofacial surgery,the author successfully completed a case of benign parotid tumor resection with the assistance of a domestic autonomous robot.The operation was successful,facial nerve function was preserved,and postoperative wound healing was good.

Diabetes mellitus(DM)is a major metabolic disease endangering global health,with diabetic ne-phropathy(DN)as a primary complication lacking curative therapy.Sporoderm-broken spores of Ganoderma lucidum(GLP),an herbal medicine,has been used for the treatment of metabolic disorders.In this study,DN was induced in Sprague-Dawley rats using streptozotocin(STZ)and a high-fat diet(HFD),and the protective mechanisms of GLP were investigated through transcriptomic,metabolomic,and network pharmacology(NP)analyses.0ur results demonstrated that GLP intervention ameliorated renal damage and inflammation levels in DN rats.Integrative metabolomic and transcriptomic analysis revealed that GLP treatment modulated glucose and cellular energy metabolisms by regulating relevant genes.GLP significantly suppressed the inflammations by impacting glucose and energy metabolism-related gene expression(Igfbp1 and Angptl4)and enhanced metabolic biomarkers of 4-Aminocatechol.In addition,NP analysis further indicated that GLP may efficiently alleviate DN via immune-related pathways.In conclusion,this study provides supportive evidence of the anti-inflammatory effects of GLP supplements,highlighting their potential for promising clinical applications in treating DN.

Traditional open head and neck surgery often leaves permanent scars,significantly affecting appearance.The emergence of surgical robots has introduced a new era for minimally invasive surgery.However,the complex anatomy of the head and neck region,particularly the oral and maxillofacial areas,combined with the high costs associated with established systems such as the da Vinci,has limited the widespread adoption of surgical robots in this field.Recently,surgical robotic platform in China has developed rapidly,exemplified by the promise shown by the KangDuo Surgical Robot(KD-SR).Although the KD-SR has achieved some results comparable to the da Vinci surgical robot in urology and colorectal surgery,its performance in complex head and neck regions remains untested.This study evaluated the feasibility,effectiveness,and safety of the newly developed KD-SR-01,comparing it with standard endoscopic systems in head and neck procedures on porcine models.We performed parotidectomy,submandibular gland resection,and neck dissection,collected baseline characteristics,perioperative data,and specifically assessed cognitive workload using the NASA-TLX.None of the robotic procedures were converted to endoscopic or open surgery.The results showed no significant difference in operation time between the two groups(P=0.126),better intraoperative bleeding control(P=0.001),and a significant reduction in cognitive workload(P<0.001)in the robotic group.In conclusion,the KD-SR-01 is feasible,effective,and safe for head and neck surgery.Further investigation through well-designed clinical trials with long-term follow-up is necessary to establish the full potential of this emerging robotic platform.

Objective To explore effects of dizocilpine (MK-801) preconditioning on excitatory amino acids and inflammatory response in rats induced by cardiac arrest-cardiopulmonary resuscitation (CACPR).Methods 18 male Sprague Dawley (SD) rats were randomly divided into three groups:control group,CA group and CA + MK-801 group.To establish rat models of CA-CPR and keep samples of serum and specimens of brain tissues for following detection.The injury of neurons was observed by HE staining and expression of N-methyl-D-aspartic acid receptor (NMDAR) in brain tissues was detected by Western blot.The concentrations of interleukin 1 beta (IL-1 β) and tumor necrosis factor (TNF)-α in serum were detected by enzyme linked immunosorbent assay (ELISA).Results Neurons in CA group were disorganized,cells shrank,nuclei pyknosis,and cytoplasmic eosinophilia,accompanied by inflammatory cell infiltration.Preconditioning with MK-801 reduced the pathological damage of neuron and degree of macrophage infiltration.The relative expression of NMDAR protein in CA group were significantly higher than that in control group (907.9 ±24.9 vs 321.6 ± 18.4,P ＜0.001).Preconditioning with MK-801 significantly decreased the expression of NMDAR in CA + MK-801 group compared with that in CA group (512.4 ± 21.1 vs 907.9 ± 24.9).The CA group showed significantly increased concentrations of IL-1 β and TNF-α than that in control group (P ＜ 0.001),and this effect was abolished by preconditioning with MK-801.CA rats treated with MK-801 showed higher concentrations of IL-1 β and TNF-α than the control group.Conclusions Cardiac arrest causes pathological injury of neurons,up-regulates expression of NMDAR and aggravates inflammatory response.These results induce the apoptosis of nerve cells.Blocking glutamate receptor with MK-801 can inhibit expression of NMDAR,decrease level of cytokines,down-regulate inflammatory reaction degree therefore to protect the brain.
