Kinesin superfamily proteins(KIFs)are motor proteins that travel along microtubules and facilitate the transport of small biological molecules within cells.Various kinesin proteins are present in the dorsal root ganglion and spinal dorsal horn,where they modulate the excitability and sensitivity of sensory neurons,contributing to the occurrence and maintenance of pathological pain.Therefore,they represent potential therapeutic targets for the treatment of pathologi-cal pain.This review provides a comprehensive overview of the recent advancements in understanding the peripheral and central mechanisms of kinesins in the context of pathological pain,offering valuable insights for the potential development of analgesic medications targeting kinesin.

Objective To investigate the safety parameters of the air-powered electrocautery hook and its advantages in laparoscopic surgery.Methods In pressure trauma experiments,21 healthy New Zealand White Rabbits were randomly divided into three groups.In each group,three sites(liver,intestine,and kidney)were selected from each rabbit,and the air-powered electrocautery hook was used under laparoscopy to apply pressure and time gradients in a cross-combination manner.The three groups of experimental rabbits were dissected at three time points:immediately after application,3 d post-application,and 7 d post-application.Pathological sections were prepared from the corresponding treated sites,and the extent of injury was assessed.In rabbit renal capsule removal experiment,another 20 healthy New Zealand White Rabbits were randomly divided into 2 groups.Renal capsule removal was performed by using an air-powered electrosurgical hook and a conventional electrosurgical hook,respectively,to compare the two groups in terms of surgical time,intraoperative bleeding volume,intraoperative complications,and the number of times of wiping speculum.Results In pressure trauma experiment,except for the intestinal tract at 3 seconds(P=0.060),the histopathological scores under 0.3 MPa pressure were significantly higher than those under 0.1 MPa(P<0.05)and 0.2 MPa(P<0.05)in all the tissues.In the tissue sampling groups at 3 d and 7 d post-surgery,no tissue damage was observed in any tissue at any time point under 0.1 MPa pressure.In rabbit renal capsule removal experiment,the aerodynamic electrocautery group had less intraoperative bleeding volume than the conventional electrocautery group[(2.9±0.5)ml vs.(3.4±0.5)ml,t=-2.280,P=0.035].There were no significant differences between the two groups in terms of surgical time,intraoperative complication rates,and the number of times of wiping speculum(P>0.05).Conclusions The safe pressure range for using the air-powered electrosurgical hook on the surfaces of the kidney and intestinal tract is within 0.2 MPa.Within the safe pressure range,blowing on tissue for 6 seconds or less is relatively safe.Using the air-powered electrosurgical hook in surgeries requiring the separation of loose connective tissue can reduce intraoperative bleeding.

Objective:To evaluate the long-term effectiveness of lingual mucosal graft ureteroplasty (LMGU) for managing long-segment (≥5 cm) ureteral strictures in a multi-institutional cohort of patients.Methods:A multi-center retrospective case series study was conducted on clinical data from 42 patients undergoing LMGU for long-segment ureteral strictures (≥5 cm) across five institutions between February 2017 and June 2024. The cohort comprised 31 males and 11 females, with an age of (43.4±12.0) years (range: 15 to 64 years) and a body mass index of (24.6±2.6) kg/m2 (range: 16.0 to 30.0 kg/m2). Strictures involved the left ureter in 24 cases and right ureter in 18 cases, demonstrating a stricture length of (6.4±1.5) cm (range: 5.0 to 11.5 cm). Surgical interventions included either onlay ureteroplasty or augmented anastomotic ureteroplasty, selected according to intraoperative findings. Intraoperative parameters, postoperative complications, and follow-up outcomes were analyzed.Results:Laparoscopic surgery was performed in 22 cases and robot-assisted surgery in 20 cases. Among the 42 patients, 22 underwent onlay ureteroplasty while 20 received augmented anastomotic ureteroplasty. The graft length was (5.9±1.8) cm (range: 3.0 to 12.0 cm), operative time (191.5±55.6) minutes (range: 105.0 to 350.0 minutes), and intraoperative estimated blood loss (86.7±73.6) ml (range: 10.0 to 400.0 ml). All procedures were successfully completed without conversion to open surgery. The postoperative hospital stay was (7.6±2.0) days (range: 4.0 to 15.0 days), with double-J stent removal at 6 to 8 weeks postoperatively. During a follow-up of (49.1±25.0) months (range: 12.0 to 99.0 months), no stricture recurrence was observed in any patient.Conclusion:LMGU is a safe, feasible, and effective long-term technique for managing long-segment (≥5 cm) ureteral strictures.

The complement system comprises intrinsic complement components,complement regulatory pro-teins,and complement receptors.Complement activation plays a role in promoting the sensitization of peripheral pain re-ceptors,enhancing immune cell activity,and participating in the regulation of axon regeneration after nerve injury.The in-teraction of the complement system contributes to the development and maintenance of pathological pain,affecting the dor-sal root ganglion neurons,spinal dorsal horn,and brain.Consequently,targeting the complement system holds promise as a therapeutic approach for neuropathic pain treatment.This paper reviews the progress in understanding the functions of the complement system and its implications in pathological pain,offering valuable insights for the future development of targeted drug therapies.

Alzheimer's disease(AD)is a common neurological degenerative disease.Collapsin response mediator protein2(CRMP2)plays an important role in the progression of AD.Hyperphosphorylation of CRMP2 results in decreased stability of axonal terminal microtubules and abnormal axoplasmic transport of neurons,which leads to abnormal mitochondrial dynamics of neurons,inhibits the ability of lysosomal autophagy,and leads to excessive activation of NMDA receptors.The phosphorylation of CRMP2 provides a new idea for AD drug develop-ment.In this review,the molecular mechanisms of CRMP2 involved in AD are reviewed,which can provide refer-ences for the development of targeted drugs.

Alzheimer's disease(AD)is a common neurodegenerative disease,which is mainly caused by brain lesions.The activation of complement system plays an important role in the process of AD lesions.The activated complement can bind to cell membrane receptors and regulate downstream signals.Therefore,inhibiting complement activation provides a new idea for AD treatment.This article reviews the progress in the mechanism and drug development of complement activation in AD,which may provide a new perspective for the diagnosis,treatment and drug development of AD.

N6-methyladenosine(m6A)denotes the addition of a methyl group to the sixth nitrogen atom of ade-nosine,a common occurrence in eukaryotic RNA.The m6A modifications govern RNA splicing,translocation,stability,and translation into proteins.The RNA methyltransferases,like methyltransferase-like protein 3(METTL3),METTL14,and Wilms'tumor 1-associated protein(WTAP),are responsible for these modifications,while the removal process in-volves demethylases,specifically fat mass and obesity-associated protein(FTO)and ALKB homolog 5(ALKBH5).Recog-nition of these modifications is facilitated by m6A-binding proteins,such as YTH family proteins and insulin-like growth factor 2 mRNA-binding proteins(IGF2BPs).The m6A modification regulators are involved in the onset and progression of non-small-cell lung cancer through multiple mechanisms.This review concentrates on the biological functions and molecu-lar mechanisms of m6A modification-related regulatory factors in the malignant progression of non-small-cell lung cancer.
