Objective: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children and adolescents, often accompanied by motor function disorders. Sarcopenia not only has skeletal muscle dysfunction but also has neurocognitive dysfunction. At present, there is no research to explore the relationship between ADHD and skeletal muscle function. The purpose of this study is to explore whether there is a causal effect between ADHD and sarcopenia. Methods: In this study, genome-wide association study data of ADHD, appendicular lean mass (ALM), hand grip strength, and walking pace (WP) were extracted from public databases. The bidirectional two-sample Mendelian randomization (MR) method was employed to investigate the correlation between ADHD and sarcopenia-related indicators, and the inverse-variance weighted analysis as the primary analysis method. Results: Based on the forward MR analysis, a potential causal relationship exists between ADHD and ALM (odds ratio [OR]=1.020, 95% confidence interval [CI]: 1.012–1.029, p<0.001). The reverse MR analysis indicates a link between WP and the risk of ADHD (OR=2.712, 95% CI: 1.609–4.571, p<0.001), with an accelerated WP increasing the likelihood of ADHD. Nevertheless, other MR analysis results did not show significant differences. Conclusion The findings of this study indicate an intricate causal relationship between ADHD and sarcopenia, suggesting the absence of a clear link. WP may be used as one of the indicators to evaluate the risk of ADHD. At the same time, we should pay more attention to the ALM of ADHD patients.

Objective To investigate the spatiotemporal expression pattern of metabotropic glutamate receptor 4(mGluR4)in the mouse cochlear basilar membrane and its dynamic changes during postnatal development until hair cell synaptic maturation.Methods Ten healthy 3-month-old C57BL/6L wild-type mice(5 males,5 females,25～35 g)were bred to obtain offspring.Cochlear samples from postnatal days 1～30(P1～P30)were analyzed.Frequency-specific auditory brainstem response(ABR)thresholds were measured at 45.2,32.0,22.6,16.0,11.3,8.0,5.6,and 4.0 kHz in P12,P14,P16,P21,and P30 mice.Immunofluorescence assay combined with confocal laser scanning microscopy was used to scan cochlear whole-mount preparations.Spatiotemporal co-localization profiling of mGluR4 and synaptic markers Ctbp2 and Snap25 was observed,and quantitative comparisons of fluorescent puncta density were performed.Results ABR testing revealed undifferentiated waveforms in all P12 mice,while 70%of P14 mice exhibited well-defined Wave I.In P14,P16,P21 and P30,mice undergoing ABR testing,50%failed to exhibit ABR waveforms when stimulated by 45.2 kHz tones,and 87.5%showed no response to 32.0 kHz stimuli.Auditory response thresholds for other frequencies progressively decreased with increasing postnatal age.Immunolocalization demonstrated stronger mGluR4 expression in inner hair cells(IHCs)versus outer hair cells(OHCs).Distinct mGluR4 puncta were observed at IHC presynaptic active zones(co-localized with Snap25)as early as P11,but showed minimal overlap with CtBP2-labeled ribbons.Quantitative analysis revealed significantly higher mGluR4 puncta density at P30 compared to P14 synapses(P<0.05).Conclusion Postnatal upregulation of mGluR4 at IHC synaptic regions correlates with functional maturation.These findings suggest mGluR4 may modulate vesicular exocytosis regulation and exert pharmacological inhibition on glutamate release,potentially influencing synaptic plasticity during auditory pathway refinement.

Objective To compare the long-term efficacy of intradiscal injection of autologous platelet-rich plasma(PRP)and intradiscal injection of autologous PRP combined with pulsed radiofrequency(PRF)therapy for discogenic back pain(DBP).Methods Prospective inclusion of 98 DBP patients who received treatment at Hai'an People's Hospital from July 2019 to December 2023 was conducted.The patients were randomly divided into study group(receiving PRP combined with PRF,n=50)and control group(receiving PRP only,n=48).The preoperative and the postoperative 1-,3-,6-,and 12-month baseline data,visual analog scale(VAS)score,Roland-Morris Disability Questionnaire(RMDQ)score,Leeds Neurological Symptoms and Signs Score(LANSS),European Society for Quality of Life Five Dimensional Questionnaire(EQ-5D)score,and the use of non-steroidal anti-inflammatory and analgesic drugs were compared between the two groups.Results There was no statistically significant differences in the baseline data and the incidence of intraoperative and postoperative adverse reactions between the two groups(both P＞0.05).At 12 months after surgery,the VAS,RMDQ,LANSS,EQ-5D scores,and the use of non-steroidal anti-inflammatory and analgesic drugs in all patients were significantly better than those before surgery(all P＜0.05).The postoperative 3-,6-,and 12-month VAS,RMDQ,LANSS,EQ-5D scores,and the analgesic dosage in the study group were significantly better than those in the control group(all P＜0.05),and the percentages of patients with pain relief greater than 50％and greater than 80％were also significantly higher than those in the control group(all P＜0.01).Conclusion for the treatment of DBP,both CT-guided intradiscal injection of autologous PRP and CT-guided intradiscal injection of autologous PRP combined with PRF can significantly improve pain,body function,and quality of life in DBP patients,and significantly reduce the use of non-steroidal anti-inflammatory and analgesic drugs.The efficacy of autologous PRP combined with PRF is remarkably better than that of autologous PRP alone.

Background and Aims:Elderly patients undergoing laparoscopic radical resection of colon cancer often experience decreased sleep quality,which may hinder postoperative recovery.Although pharmacological interventions are commonly used in clinical practice to improve postoperative sleep,conventional medications may lead to adverse effects such as delirium and dependence.This study aimed to evaluate the effect of a non-pharmacological intervention—buccal acupuncture combined with ultrasound-guided stellate ganglion block(SGB)—on postoperative sleep quality in elderly patients.Methods:A total of 60 elderly patients who underwent laparoscopic radical resection of colon cancer at the Forth Hospital of Changsha from February to August 2024 were enrolled.Using a random number table,the patients were divided into two groups:30 in the control group(SGB alone)and 30 in the study group(SGB combined with buccal acupuncture).Perioperative mean arterial pressure(MAP),heart rate(HR),postoperative visual analogue scale(VAS)scores,Pittsburgh Sleep Quality Index(PSQI)scores,and the incidence of adverse events were recorded and analyzed.Results:There were no statistically significant differences in baseline characteristics between the two groups(all P>0.05).The study group showed significantly lower intraoperative and postoperative HR and MAP compared to the control group(all P<0.05).VAS scores at 6,24,and 48 h postoperatively,as well as PSQI scores on postoperative days 1,3,and 5,were significantly lower in the study group(all P<0.05).Additionally,the incidence of drowsiness was significantly reduced(P<0.05).No significant differences were found between the two groups in terms of nausea,vomiting,or agitation(all P>0.05).Conclusion:The combination of buccal acupuncture and SGB during the perioperative period can effectively improve postoperative sleep quality,alleviate pain,and reduce adverse reactions in elderly patients undergoing laparoscopic radical resection of colon cancer.This safe and effective non-pharmacological intervention holds promising clinical application value.

Objective:To explore the clinical application value of press-needle assisted sedation therapy in sedation treatment of intensive care unit (ICU) under bispectral index (BIS) monitoring.Methods:A total of 30 critically ill patients admitted to the ICU of the China-Japan Friendship Hospital from July 2024 to January 2025 were selected. A prospective self before-after control method was used. On the basis of conventional analgesic and sedative drug treatment, traditional Chinese medicine press-needles were combined to stimulate the head emotion area, Yintang (GV29), Hegu (LI4), Neiguan (PC6), and Zusanli (ST36). The BIS, dosages of remifentanil and propofol, respiratory and circulatory functions, and lactate levels before and after treatment were compared.Results:The BIS value dropped to stability (21.90±13.67)min after press-needle treatment, with a decrease of (5.73±1.42) ( P<0.05). The dosage of propofol within 8 h after press-needle treatment was reduced by (1.08±0.33)mg/kg compared with that before treatment ( P<0.05). There were no significant differences in heart rate, blood pressure, oxygenation index, and lactate level before and after treatment (all P>0.05). Conclusions:Press-needle assisted sedation therapy can improve the sedative effect, reduce the dosage of propofol sedatives, and has good safety.
