ObjectiveTo analyze the research hotspots and development trends in the field of spinal cord stimulation (SCS) for spinal cord injury (SCI). MethodsLiterature about SCS for SCI was retrieve from the Web of Science (WOS) Core Collection database, with a time range from January, 1999 to July, 2025. VOSviewer 1.6.20 and CiteSpace 6.4.R2 were used to analyze the annual publication volume, countries, authors, institutions, journals and keywords. ResultsA total of 636 literatures were included. From 1999 to 2025, the overall publication trend in this field showed an upward trajectory, with recent years fluctuating but tending to stabilize. The country with the most publications was the United States (429 papers), followed by Russia (98 papers) and China (70 papers). The institution with the highest number of publications was the University of California, Los Angeles (76 papers), the author with the most publications was V. Reggie Edgerton (70 papers), and the journal with the most publications was Journal of Clinical Medicine (31 papers). The most frequently cited study focused on exploring the combination of epidural spinal cord stimulation with task-specific training to restore motor function in patients with complete SCI. Keyword analysis showed that the research hotspots in this field were mainly focused on neuroregulation mechanisms, recovery of motor and autonomic nervous dysfunction, artificial intelligence, closed-loop stimulation and brain-computer interface technology innovations. In recent years, the research focus gradually shifted from basic mechanisms to personalized and precise multifunctional rehabilitation strategies. ConclusionThe field of SCS for SCI has undergone phases of basic mechanism exploration and clinical application expansion. Current research hotspots and future trends focus primarily on the development of new stimulation paradigms and combined innovative technologies.

Objective To explore the efficacy and safety of blue laser vaporization in the treatment of large-volume (＞80 mL) benign prostatic hyperplasia (BPH). Methods A retrospective analysis was conducted on the clinical data of 149 BPH patients with prostate volume＞80 mL who underwent blue laser vaporization at our hospital during Aug. 2023 and Aug. 2025. The 1-month postoperative maximum urinary flow rate (Qmax) and international prostate symptom score (IPSS), operation time, postoperative hemoglobin drop, bladder irrigation volume, catheter indwelling time, and incidence of postoperative complications were recorded and analyzed. Results All operations were successfully completed, without conversion to other approaches. The operation time was (41.47±11.05) minutes, postoperative hemoglobin drop (2.78±1.19) g/L, bladder irrigation volume (9.97±1.49) bags, and catheter indwelling time (3.30±1.85) days. One month after surgery, the Qmax was significantly higher than the preoperative value [(20.19±3.39) mL/s vs. (2.39±2.17) mL/s], while the IPSS was significantly lower [(4.46±0.87) vs. (27.69±2.06)], with statistically significant differences (P＜0.001). Postoperative complications included 1 case of incontinence (0.67%), 2 cases of urethral stricture/bladder neck contracture (1.34%), and 1 case of secondary bleeding (0.67%), all of which improved with symptomatic treatment. Conclusion Blue laser vaporization is effective for treating large-volume BPH, with advantages such as minimal bleeding risk, short operation time, fast recovery and safety.

ObjectiveTo investigate the potential mechanism of heat-sensitive moxibustion on chronic atrophic gastritis （CAG） through the phosphoinositide 3-kinase/protein kinase B （PI3K/Akt） signaling pathway. MethodsFifty-eight SD rats were randomly divided into blank group （n=14） and modeling group （n=44）. Rats in the blank group were fed routinely， while the rats in the modeling group received drinking water containing 1-methyl-3-nitro-1-nitrosoguanidine （MNNG） at a concentration of 140 μg/ml， combined with irregular fasting and feeding for 12 weeks to establish CAG model. After successful modeling， the rats were randomly divided into model group （n=10）， inhibitor group （n=10） and moxibustion group （n=20）. After 40 minutes of suspended moxibustion at "Zhongwan" （CV 12） daily， the rats in the moxibustion group were divided into heat-sensitive moxibustion group （n=10） and non-heat-sensitive moxibustion group （n=9） according to the change of tail temperature during moxibustion. The inhibitor group was bound for 40 minutes daily， and then administered with PI3K/Akt signaling pathway inhibitor， rapamycin solution， by gavage at a dose of 1 mg/kg. The model group received intragastric administration of 1 ml/kg normal saline after 40 minutes of restraint stress each day. All interventions were administered once daily for 28 consecutive days， while the blank group received no intervention. After the intervention finished， the body weight of rats in each group was compared. HE staining was used to observe the histopathological changes of gastric mucosa. The apoptosis-positive rate of gastric mucosal cells was detected by TUNEL assay. Immunohistochemistry was performed to determine the protein levels of matric metalloproteinase-7 （MMP7）， vascular endothelial growth factor A （VEGFA） and epidermal growth factor receptor （EGFR） in gastric mucosa. The mRNA expression levels of PI3K， Akt and mammalian target of rapamycin （mTOR） in gastric mucosal tissues were detected by qPCR. The protein levels of phosphorylated Akt （p-Akt） and phosphorylated mTOR （p-mTOR） in rat gastric mucosal tissues were measured by Western Blotting. ResultsCompared to the blank group， rats in all other groups exhibited decreased body weight， significantly increased gastric mucosal cell apoptosis-positive rates， elevated protein levels of MMP7， VEGFA and EGFR in gastric mucosa， increased mRNA expression levels of PI3K， Akt and mTOR， and enhanced protein expression levels of p-Akt and p-mTOR （P＜0.05 or P＜0.01）. Histopathological examination revealed thinning of the gastric mucosa， glandular disorganization and atrophy， accompanied by intestinal metaplasia.Compared to the model group， the heat-sensitive moxibustion group， the non-heat-sensitive moxibustion group and the inhibitor group all showed significant improvements in the above-mentioned indicators （P＜0.05 or P＜0.01）. Compared to the heat-sensitive moxibustion group， the non-heat-sensitive moxibustion group and the inhibitor group exhibited increased positive rates of gastric mucosal cell apoptosis； the non-heat-sensitive moxibustion group showed increased protein levels of MMP7， VEGFA and EGFR， as well as mRNA expression levels of PI3K， Akt and mTOR， and protein expressions of p-Akt and p-mTOR； the inhibitor group exhibited elevated protein expression level of EGFR （P＜0.05 or P＜0.01）. Histopathological examination showed that the gastric mucosal glands in the heat-sensitive moxibustion group were arranged more regularly， with an approximately normal structural appearance. ConclusionHeat-sensitive moxibustion can improve the body weight of CAG rats and repair gastric mucosal injury. Its therapeutic effects may be mediated by inhibiting excessive activation of gastric mucosal PI3K/Akt signaling pathway， thereby reducing gastric mucosal cell apoptosis.

BACKGROUND:The absence of blood vessels in tendon tissue makes tendon repair challenging.Therefore,improving tendon healing and raising the efficacy of stem cell and other therapeutic cell transplantation after tendon damage have become hotspots for research in both clinical and scientific contexts. OBJECTIVE:The stem cells and gelatin microcarrier scaffold were joined to form tissue engineered stem cells.Human umbilical cord mesenchymal stem cells cultured in gelatin microcarriers were used to investigate the therapeutic impact and mode of action on tendinopathy healing in rats in vitro and In vivo. METHODS:(1)In vitro cell experiments:After seeding human umbilical cord mesenchymal stem cells with three-dimensional gelatin microcarriers,the cell vitality and survival were assessed.Human umbilical cord mesenchymal stem cells conventionally cultured were cultured as controls.(2)In vivo experiment:Adult SD rats were randomly assigned to normal group,tendinopathy group,2D group(tendinopathy+conventional culture of human umbilical cord mesenchymal stem cells),and 3D group(tendinopathy+gelatin microcarrier three-dimensional culture of human umbilical cord mesenchymal stem cells),with 6 rats in each group.Four weeks after therapy,animal behavior tests and histopathologic morphology of the Achilles tendon was examined. RESULTS AND CONCLUSION:(1)In vitro cell experiments:the seeded human umbilical cord mesenchymal stem cells on gelatin microcarriers showed high viability and as time went on,the stem cell proliferation level grew.Compared with the control group,3D stem cell culture preserved cell viability.(2)In vivo experiment:Following a 4-week treatment,the 3D stem cell culture group showed a significant improvement in both functional recovery of the lower limbs and histopathological scores when compared to the tendinopathy group.The 2D stem cell culture group also showed improvement in tendinopathy injury,but its effect is not as much as the 3D stem cell culture group.(3)The outcomes demonstrate that human umbilical cord mesenchymal stem cells cultured with three-dimensional gelatin microcarrier can promote the repair and regeneration of tendon injury tissue,and the repair effect is better than that of conventional human umbilical cord mesenchymal stem cells.

Objective:To explore the influencing factors of the subjective well-being of elderly individuals and improve the accuracy of well-being predictions.Methods:A multi-stage stratified sampling method was conducted in Guangdong province and Guangxi Zhuang autonomous region from August 2019 to October 2020. The health status and subjective well-being of older adults were assessed using a self-administered multidimensional health questionnaire, while overall well-being was evaluated with a single-item 5-point scale. The statistical analysis was performed using R software (version 4.3.2), with analytical methods including χ2 tests, univariate analysis, quantile regression and random forest model. Results:A total of 2 620 participants were recruited, and 70.9% of whom reported feeling happy.The depression symptom score of the elderly was 3.00(1.00, 6.00), emotional status score was (28.26±4.14), activities of daily living (ADL) score was 69.00(52.00, 81.00), and the body mass index(BMI) was (22.68±3.81)kg/m 2.The quantile regression results indicated that marital status (married)(Q 10: β=0.049; Q 50: β=0.014; Q 90: β=0.005) and depressive symptoms (no depression, depressive tendency)(Q 10: β=1.000; Q 50: β=1.000; Q 90: β=0.025) had varying effects on older adults' subjective well-being across three quantiles (Q 10, Q 50, Q 90)(all P<0.05). In contrast, social activity (no social activity)(Q 10: β=-0.072; Q 50: β=-0.011; Q 90: β=-0.006), ADL (severe disability, moderate disability, mild disability)(Q 10: β=-0.103, Q 50: β=-0.006, Q 90: β=-0.048; Q 10: β=-0.063, Q 50: β=-0.012, Q 90: β=-0.005; Q 10: β=-0.078, Q 50: β=-0.016, Q 90: β=-0.009), and emotional status (poor emotion, fair emotion)(Q 10: β=-0.261, Q 50: β=-0.009, Q 90: β=-0.025; Q 10: β=-0.140, Q 50: β=-0.017, Q 90: β=-0.029) had a negative impact on elderly subjective well-being at the three quantile points(all P<0.05). Random forest results indicated that depressive symptoms, ADL, emotional status, household monthly income per capita, BMI, social activity, multimorbidity status, and marital status were the most important determinants of subjective well-being. Conclusion:Depressive symptoms and emotional status have a significant impact on the subjective well-being of older adults. Additionally, ADL, household income per capita, BMI, and social engagement also play important roles in influencing well-being, while the emotional support provided by marriage should not be overlooked.

Objective To conduct a rapid health technology assessment(rHTA)of the efficacy,safety,and cost-effectiveness of tirzepatide for the treatment of type 2 diabetes mellitus(T2DM),and to provide evidence for clinical medication.Methods PubMed,Web of Science,Embase,Cochrane Library,WanFang Data,CNKI databases,and health technology assessment(HTA)websites were searched to collect systematic reviews/Meta-analysis,pharmacoecomic literature and HTA reports of tirzepatide in the treatment of T2DM from inception to February 28,2025.Two researchers independently conducted literature screening,data extraction,and quality assessment,and then summarized and analyzed the results.Results A total of 13 articles were included,comprising 2 HTA reports,8 systematic reviews/Meta-analyses,and 3 pharmacoeconomic studies.In terms of efficacy,tirzepatide outperformed placebo or other antidiabetic drugs in reducing glycated hemoglobin(HbA1c),increasing the rate of HbA1c＜7％,lowering blood glucose,and reducing weight.The antihyperglycemic and weight-loss effects of tirzepatide were dose-dependent,and it also had certain advantages in reducing the risk of cardiovascular events and renal composite endpoint events.Regarding safety,the incidence of gastrointestinal adverse events in the tirzepatide group was higher than that in the placebo group and the insulin group,mainly manifested as diarrhea,nausea,and vomiting.However,it did not increase the risk of serious gastrointestinal adverse events,nor did it increase the risk of hypoglycemia and pancreatitis.In terms of cost-effectiveness,tirzepatide had cost-utility and cost-effectiveness advantages compared with semaglutide and other antidiabetic drugs.Conclusion Compared with other antidiabetic drugs,tirzepatide has better efficacy,safety,and cost-effectiveness in the treatment of T2DM.
