Objective: To investigate the clinical efficacy and safety of pudendal nerve modulation (PNM) in the treatment of female pudendal neuralgia (PN)，so as to promote the clinical application of this technique. Methods: A retrospective analysis was conducted on 20 female PN patients who failed conservative treatment at Gongli Hospital during Nov.2020 and Oct.2023.All patients underwent simultaneous PNM and sacral nerve modulation (SNM) with the assistance of 3D printing navigation.Dual-stage test electrodes for PNM and SNM were implanted，followed by alternate therapeutic trial for each modality.Secondary conversion rates and longitudinal outcomes，including visual analogue score (VAS)，patient health questionnaire-9 (PHQ-9)，and quality of life (QoL) scores were compared preoperatively，post-stage Ⅰ，and at 3，6，and 12 months post-stage Ⅱ. Results: All operations were successful.After the trial phase，the secondary conversion rate for PNM was significantly higher than that for SNM; 16 patients (16/20，80%) chose the second-phase PNM implantation surgery，3 (3/20，15%) chose second-phase SNM implantation，and 1 (1/20，5%) had electrodes removed due to ineffective results from both trials.Further assessment revealed that the improvements in VAS，PHQ-9，and QoL scores for PNM patients were significantly better than those for SNM patients after the first phase of surgery and at 3，6 and 12 months after the second-phase conversion (P<0.05).No complications such as electrode migration or infection were observed during the follow-up of 12-15 months. Conclusion: PNM provides more effective relief of pain symptoms and improvements in depressive states for female PN patients compared to SNM.With the assistance of 3D printing navigation，the operation is simple and safe，and offers stable therapeutic effects.It is worthy of clinical promotion and application.

Objective:To explore the clinical application value of optical navigation system（ONS）-guided sacral neuromodulation（SNM）electrode implantation for precise puncture.Methods:?This study was a randomized，controlled trial. Patients who underwent SNM electrode implantation at the Gongli Hospital，Pudong New Area，Shanghai，from February 2024 to March 2025 were included. Inclusion criteria：aged 18?80 years，meeting the indications recommended by the Chinese expert consensus on the clinical application of sacral neuromodulation or expanded applications，and having completed pelvic CT and MRI examinations to ensure image quality for navigation system use. Exclusion criteria：progressive neurological diseases，severe urinary tract infections，urinary tract obstruction，or other conditions that may affect surgical outcomes and safety. Patients were randomly divided into two groups using a random number table and a single-blind design was implemented. The two groups underwent different puncture guidance methods in the stage Ⅰ surgery，but other treatments and follow-up measures were consistent.The experimental group used ONS-guided puncture with preoperative pelvic CT and MRI scans for multimodal image fusion and 3D reconstruction and software-based puncture path planning for real-time intraoperative guidance. The control group used X-ray-guided cross-positioning，determining the S3 sacral foramen for puncture based on anatomical landmarks with a metal positioning ruler under fluoroscopy. The puncture path was planned using software to achieve real-time intraoperative guidance. Intraoperative indicators（number of punctures，puncture time，electrode contact points，minimum effective voltage，X-ray fluoroscopy time，radiation dose，total surgical time）and postoperative outcomes（complications，pain scores，stage Ⅱ permanent implantation rates）were compared between the two groups to assess the advantages and feasibility of ONS-guided sacral nerve electrode implantation.Results:?A total of 35 patients were included in each group. The experimental group had fewer intraoperative puncture attempts［2.0（2.0，3.0）vs. 5.0（4.0，7.0）］and shorter puncture procedure time［7.5（6.0，10.0）min vs. 14.0（12.0，18.0）min］，indicating more accurate and efficient ONS-guided puncture. There was no statistical difference in the number of electrode contact points between the two groups［3.0（3.0，4.0）vs. 3.0（3.5，3.8）， P = 0.374］，but the experimental group had a lower effective voltage［1.8（1.8，2.5）V vs. 2.5（1.8，3.0）V］and shorter stimulator adjustment time［10.0（8.0，12.0）min vs. 16.0（13.0，20.0）min］. The experimental group had shorter intraoperative X-ray fluoroscopy time［1.6（1.1，2.2）min vs. 4.6（3.8，6.0）min］，lower radiation dose［165.8（107.6，205.3）mGy vs. 427.4（325.1，636.5）mGy］，shorter total surgical time［52.0（49.0，57.8）min vs. 68.0（62.0，74.0）min］，less intraoperative blood loss［4.0（4.0，5.0）ml vs. 6.0（5.0，7.0）ml］，and a lower proportion of patients requiring supplemental local anesthesia［14.3%（5/35）vs. 40.0%（14/35）］. The postoperative wound infection rates were not statistically different between the two groups［0 vs. 2.9%（1/35）， P = 1.000］，but the experimental group had significantly lower pain scores on postoperative day 1［（1.9 ± 1.1）vs.（3.2 ± 1.4）］and a higher stage Ⅱ permanent implantation rate［85.7%（30/35）vs. 65.7%（23/35）］，with statistically significant differences（ P < 0.05）. Conclusions:?ONS-guided SNM electrode implantation reduces the number of puncture attempts，surgical time，and X-ray radiation，effectively lowers the effective voltage，and increases the stage Ⅱ permanent implantation rate.

Objective To explore the molecular mechanism of autophagy mediated by the protein kinase B(AKT)/mammalian target protein of rapamycin(mTOR)pathway in the rehabilitation of muscle atrophy associated with rotator cuff tears(RCTs).Methods Forty male C57BL/6J mice were randomly assigned to the following four groups:sham group,RCTs group,RCTs+exercise group,and RCTs+exercise+rapamycin group,with 10 mice in each group.On the eighth week after grouping,healing of the bone-tendon interface and muscle cell atrophy were analyzed by histology.The mRNA expression levels of muscle-atrophy-related genes(Atrogin-1,Bnip 3,MuRF-1)in supraspinatus muscle tissue were measured by real-time quantitative reverse transcription polymerase chain reaction.The expression of LC3 and AKT/mTOR signal pathway proteins in the supraspinatus muscle tissue of the groups was detected by Western blot,and the degree of autophagy in each group was analyzed by transmission electron microscope.Results Compared with the sham operation group,in RCTs group's maturity score for the bone-tendon interface at the supraspinatus tendon anchorage and the cross-sectional area of the supraspinatus muscle fibers decreased significantly(P＜0.001),while muscle loss and the expression of Atrogin-1,Bnip 3,and MuRF-1 increased significantly(P＜0.001).Compared with the RCTs group,the RCTs+exercise group showed a significant increase in bone-tendon interface maturity score and cross-sectional area of the supraspinatus muscle fibers(P＜0.01)and a decrease in muscle loss and the expression of Atrogin-1,Bnip 3,and MuRF-1(P＜0.01).Compared with the sham group,the RCTs group's LC3Ⅰ/LC3Ⅱ and degree of autophagy in the supraspinatus muscle increased significantly(P＜0.001),while p-AKT/AKT and p-mTOR/mTOR expression decreased significantly(P＜0.01).Compared with RCTs group,the RCTs+exercise group's LC3Ⅰ/LC3Ⅱ and degree of autophagy decreased significantly(P＜0.01)and p-AKT/AKT and p-mTOR/mTOR expression increased significantly(P＜0.001).The addition of rapamycin significantly reversed the rehabilitation effect of exercise in the RCTs group.Conclusions This study confirmed the anti-atrophy effect of exercise rehabilitation in RCT diseases and showed that its mechanism is related to AKT/mTOR signal activation,which inhibits autophagy.

Tumors are complex, highly heterogeneous diseases that place an enormous burden on the world's healthcare systems. Updating understanding of tumor initiation and progression is critical and the current breakthrough lies in cancer neuroscience, which focuses on the crosstalk between neural components and tumors. Neuropeptides are a class of highly potent peptides, that perform the physiological functions of neurotransmitters, neuromodulators, and endocrine hormones. Currently, many studies have shown that many cellular components of the tumor microenvironment express neuropeptides and their receptors and that neuropeptides may play an important role in their cellular communication. In addition, neuropeptides and their receptors affect cancer hallmarks such as proliferation, invasion and metastasis, angiogenesis, immune escape, metabolic reprogramming, and others. More importantly, neuropeptides may also affect some tumor comorbidities such as insomnia, depression, anorexia, cancer pain, and others. Targeting neuropeptides in combination with new therapeutic strategies may significantly advance anti-tumor therapy, not only for treating the tumor itself but also for improving the patient's quality of life.

With the acceleration of societal aging, heart failure in the elderly—characterized by a complex metabolic imbalance—has emerged as a pivotal challenge in public health.This condition severely compromises the physical well-being and quality of life among senior populations, primarily due to a pronounced imbalance between cardiac energy supply and demand.Among the various interventions studied, photosynthesis in plants, the principal energy source for aerobic organisms, presents a novel avenue for exploration.By effectively converting solar energy into chemical energy, photosynthesis sustains plant life.Introducing its principles into heart failure treatment could potentially optimize metabolism for elderly patients while significantly reducing oxidative stress and inflammation.Further investigations suggest that the antioxidants and bioactive byproducts generated during photosynthesis may play critical roles in heart failure treatments, particularly in modulating inflammatory pathways.In summary, emulating the mechanisms of photosynthesis could represent a promising strategy for treating heart failure in the elderly.This review aims to delve deeply into the application of photosynthesis in heart failure treatments for older adults and its underlying mechanisms, with the hope of providing insights and guidance for future endeavors in geriatric medicine.

Background:Liver cirrhosis is characterized by chronic inflammation,progressive fibrosis,and eventual liver dysfunction,and poses a major global health challenge.Aims:To assess the global burden of liver cirrhosis and its risk factors from 1990 to 2021.Methods:Using data extracted from the Global Burden of Diseases,Injuries,and Risk Factors Study(GBD)2021,the incidence,mortality,disability-adjusted life years(DALYs),and their age-standardized rates of liver cirrhosis were analyzed.Furthermore,a stratified analysis was conducted by sex,age,region,and etiology,with projections of the trends in the next 15 years.Results:Compared to 1990,the global incidence number of liver cirrhosis in 2021 was increased by 58.2%,the death number and DALYs rose by 39.5%and 27.9%,respectively.While the global age-standardized incidence rate(ASIR)showed a slight increase,the age-standardized death rate(ASDR)and DALY rate continued to decline.Both ASIR and ASDR exhibited negative correlations with the sociodemographic index(SDI).All age-standardized rates were higher in males than in females.Since 1990,the incidence rate increased in younger populations,while the mortality and DALY rates declined in most age groups.Non-alcoholic fatty liver disease(NAFLD)emerged as the leading cause of incidence,whereas chronic hepatitis B and C remained the primary contributors to deaths and DALYs.The incidence of NAFLD was prominent in high and high-middle SDI regions,while chronic hepatitis B was concentrated in low SDI regions.Projections to 2036 indicated a continuing rise in ASIR,and declines in ASDR and DALY rate.The incidence of chronic hepatitis B was projected to decrease markedly,whereas that of NAFLD was expected to continue increasing.Conclusions:Between 1990 and 2021,the global incidence of liver cirrhosis showed a modest increase;in contrast,both mortality and DALY rates demonstrated a steady decline.Burden of liver cirrhosis poses notable regional disparities.NAFLD dominates incidence in high-income regions,while viral hepatitis remains predominant in low-income areas,highlighting the need for region-specific prevention strategies.

Objective:To explore the effects of LncRNA DLEU2 on the migration and proliferation of oral squamous cell carcino-ma(OSCC)cells by regulating the miR-186-5p/insulin-like growth factor 2 mRNA binding protein 3(IGF2BP3)axis.Methods:QRT-PCR and Western blot were applied to detect the mRNA and protein levels of LncRNA DLEU2,miR-186-5p,and IGF2BP3 in OSCC cell line SCC-25 and human normal oral keratinocyte line NOK,respectively.SCC-25 cells were transfected with si-DLEU2,miR-186-5p inhibitor and negative control respectively.The relationship between LncRNA DLEU2,miR-186-5p and IGF2BP3 was verified by double luciferase reporter gene assay.qRT-PCR was applied to detect the mRNA expression of LncRNA DLEU2 and miR-186-5p in SCC-25 cells.CCK-8 test was applied to detect the proliferation of SCC-25 cells.Flow cytometry was applied to detect the apoptosis rate of SCC-25 cells.Transwell assay was used to detect cell invasion and migration.Western blot was used to detect EMT-associated and IGF2BP3 protein levels.Results:Silencing LncRNA DLEU2 decreased the proliferative ac-tivity,migration and invasion of SCC-25 cells and decreased the protein levels of N-cadherin and Vimentin,increased the apopto-sis rate,miR-186-5p expression and E-cadherin protein levels.Down-regulation of miR-186-5p weakened the inhibitory effect of silenced LncRNA DLEU2 on the malignant phenotype of SCC-25 cells.LncRNA DLEU2 negatively regulated the miR-186-5p/IGF2BP3 axis.Conclusion:Silencing LncRNA DLEU2 may down-regulate the expression of IGF2BP3 by up-regulating miR-186-5p,inhibites the proliferation,migration,and invasion of SCC-25 cells,and promotes the apoptosis of the cells.
