ObjectiveTo investigate the incidence， glucolipid metabolism characteristics， and associated factors of postoperative overweight/obesity in children and adolescent with craniopharyngioma. MethodsA retrospective study was conducted using follow-up data from 44 patients （aged 0-18 years） diagnosed with craniopharyngioma who underwent surgical treatment and received follow-up care at Sun Yat-sen Memorial Hospital， Sun Yat-sen University， between January 2006 and February 2024. The incidence and glucolipid metabolism characteristics of overweight/obesity were summarized， and potential influencing factors were analyzed. ResultsA total of 44 patients were enrolled. The mean age at surgery was （8.57 ± 4.25） years， and the mean age at last follow-up was （16.02 ± 5.36 ）years. The mean follow-up duration was （7.45 ± 4.64） years （range， 8 months to 17.5 years）. The preoperative incidence of overweight/obesity was 40.91% （predominantly overweight， 27.27%）， which increased to 68.18% postoperatively （predominantly obesity， 50.00%）. Postoperatively， all patients （44/44， 100%） underwent fasting plasma glucose （FPG） testing， among whom 2 （4.55%） had impaired fasting glucose （IFG）. Fasting insulin （FINS） was measured in 20 patients， and insulin resistance was identified in 11 （55.00%）. Oral glucose tolerance testing （OGTT） with insulin release assessment was performed in 12 patients， and all （100%） exhibited abnormal insulin secretion， including 5 （41.67%） with hyperinsulinemia and 3 （25.00%） diagnosed with diabetes mellitus （DM）. All patients （44/44， 100%） underwent lipid profile assessment. The incidence of dyslipidemia was 81.82% （36/44）， including elevated non-high-density lipoprotein cholesterol （29/44， 65.91%）， hypertriglyceridemia （29/44， 65.91%）， low high-density lipoprotein cholesterol （22/44， 50.00%）， and mixed hyperlipidemia （13/44， 29.55%）. Logistic regression analysis indicated that preoperative overweight/obesity and postoperative abnormal glucose metabolism were significant factors associated with postoperative overweight/obesity. Compared with normal-weight patients， those with postoperative overweight/obesity had higher FINS levels （14.22 mU/L vs. 3.57 mU/L）， higher insulin resistance index（HOMA-IR） （2.88 vs. 0.52）， and a higher incidence of abnormal glucose metabolism （77.78% vs. 23.08%）. However， no significant difference was observed in the incidence of dyslipidemia （94.44% vs. 73.08%）. ConclusionsChildren and adolescent with craniopharyngioma exhibit a higher incidence of overweight/obesity than healthy peers preoperatively， which becomes more pronounced after surgery. This is accompanied by a high incidence of glucolipid metabolic disorders， placing these patients at increased risk of metabolic syndrome， which warrants clinical attention and regular metabolic assessment. In patients who develop postoperative obesity， particular attention should be given to the risk of glucose metabolism abnormalities， and further monitoring of glucose homeostasis is recommended.

Objective:To investigate the effects of methylphenidate combined with exercise intervention on at-tention,self-awareness and problem behaviors in children with attention deficit hyperactivity disorder(ADHD).Methods:A retrospective analysis was conducted on 106 children with ADHD receiving methylphenidate treat-ment.Based on whether exercise intervention was applied,participants were divided into the joint intervention group(n=49)and the control group(n=57).The Integrated Visual and Auditory Continuous Performance Test,Piers-Harris Children's Self-Concept Scale,and Conners Parent Symptom Questionnaire(PSQ)were used to measure children's attention,self-awareness,and problem behaviors.Results:After intervention,children in the joint inter-vention group had shorter reaction time,fewer omissions and errors,and lower PSQ scores(in all dimensions except anxiety and depession)than those in the control group.Additionally,their scores on the full response control quo-tient,full attention quotient,auditory response control quotient,visual response control quotient,auditory attention quotient and visual attention quotient,and Piers-Harrisscores in each dimension were higher than those in the control group(Ps＜0.05).Conclusion:Methylphenidate combined with exercise intervention could effectively enhance at-tention and self-awareness of children with attention deficit hyperactivity disorder,and reduce problem behaviors.

Objective:To investigate the relationship between the severity of pharyngolaryngeal sensory impairment and swallowing biomechanics as well as the risk of penetration-aspiration in patients with dysphagia following infratentorial stroke.Methods:This retrospective cross-sectional study enrolled 51 patients with dysphagia following infratentorial stroke hospitalized in the Department of Rehabilitation Medicine of The Third Affiliated Hospital of Sun Yat-sen University between January 2022 and December 2023. Participants were categorized into three groups: normal sensation group [15 males, 2 females; age range 29-76 (56.0±13.3)years], diminished sensation group[16 males, 3 females; age range 38-80(62.0±11.8)years], and absent sensation group [14 males, 1 female; age range 44-75 (60.0±9.7)years]. All patients underwent laryngoscopy and videofluoroscopic swallowing study, which included pharyngolaryngeal sensory testing and Penetration-Aspiration Scale assessment. Swallowing temporal parameters were quantitatively analyzed. Group comparisons for different variable types were conducted using the Chi-square test, one-way ANOVA, and the Kruskal-Wallis test. The correlation between sensory groups and Penetration-Aspiration Scale scores was assessed using Spearman′s correlation analysis. Logistic regression was employed to analyze the impact of pharyngolaryngeal sensory function on penetration-aspiration events.Results:Among the 51 patients, 33.33% (17/51) had normal pharyngolaryngeal sensation, while, 66.67% (34/51) exhibited sensory impairment. The normal sensation group exhibited a significantly longer laryngeal vestibule closure (LVC) time [792 (643, 1 205) ms] compared to the diminished [528 (380, 776) ms] and absent sensation groups [380 (322, 404) ms] ( H=6.502, P=0.039). Additionally, the upper esophageal sphincter opening time was longer in the normal sensation group than in the absent sensation group [528 (371, 710) ms vs 182 (0, 710) ms, H=6.003, P=0.049]. Correlation analysis indicated a significant negative correlation between the severity of sensory impairment and Penetration-Aspiration Scale scores ( r=-0.366, P=0.008). Logistic regression analysis demonstrated that greater sensory impairment was an independent risk factor for penetration-aspiration ( OR=9.29, 95%CI=1.57-54.77, P=0.014). Conclusion:Pharyngolaryngeal sensory deficits are common after infratentorial stroke dysphagia and are significantly associated with impaired swallowing biomechanics and increased aspiration risk. The severity of sensory deficit is a key determinant of penetration-aspiration risk, highlighting its value in risk stratification and therapeutic decision-making for dysphagia.

Objective:To seek any correlation between cortical activity and the swallowing of dysphagia patients with infratentorial stroke, and to observe any effect of three-needle acupuncture of the tongue on such activity.Methods:Thirty infratentorial stroke survivors with dysphagia were randomly divided into a tongue three-needle group and a sham acupuncture group, each of 15. Functional near-infrared spectroscopy was used to monitor changes in the concentration of oxygenated hemoglobin (ΔHbO 2) at rest, during acupuncture (or sham acupuncture), during real or sham electro-acupuncture, and at rest after the acupuncture or sham acupuncture treatment. The Modified Rankin Scale, a Penetration-Aspiration Scale (PAS), and the Functional Oral Intake Scale were employed to assess overall functional disability and the swallowing of both groups. Results:At rest the average ΔHbO 2 concentrations recorded in the left primary motor cortex, the left dorsolateral prefrontal cortex and the left premotor cortex in both groups were positively correlated with the PAS scores. During the acupuncture ΔHbO 2 concentration in the right inferior frontal gyrus and the left middle temporal gyrus increased significantly in the tongue three-needle group. It decreased significantly in the left somatosensory cortex and the left primary motor cortex. Conclusion:Three-needle acupuncture of the tongue induces changes in cortical activity in infratentorial stroke survivors with dysphagia, suggesting a potential technique for improving disordered swallowing.

Objective:To observe any effect of intermittent theta burst stimulation (iTBS) of the prefrontal lobe on dysphagia and impaired cognition, and to explore the neural mechanisms involved.Methods:Twenty-eight patients with dysphagia and mild cognitive impairment were randomly divided into an iTBS group of 16 and a control group of 11. The iTBS group received 20 minutes of iTBS (2 seconds on and 8 seconds off) of the right dorsal lateral prefrontal cortex (DLPFC) once daily for 2 weeks, with the intensity at 80% of the resting movement threshold of the right abductor pollicis brevis, while the control group was given sham iTBS. Before and after the treatment, both groups′ cognitive functioning was evaluated using the Montreal Cognitive Assessment Scale (MoCA), a trial marking test, a digit span test and a Stroop color word test. Video-fluoroscopy was used to record oral transmission times (OTTs), hyoid bone anterior displacement and hyoid bone upward displacement during swallowing. Resting-state functional magnetic resonance imaging measured the amplitude of low-frequency fluctuation (ALFF), regional homogeneity (ReHo) and functional connectivity in the patients′ brains.Results:Before the treatment there was no significant difference in the average indices of cognition or swallowing function between the 2 groups. Afterward the average MoCA score had increased significantly in both groups, with the improvement in the iTBS group significantly greater than that of the controls. Average OTT had shortened significantly in both groups, with significantly greater improvement in the iTBS group. The magnetic resonance imaging showed that after iTBS treatment, local excitation indicators and functional connections in several brain regions had changed. ALFF and ReHo in the right anterior cuneus had increased, ReHo in the left middle temporal gyrus, the orbital region of the left inferior frontal gyrus and the left middle cingulate gyrus had decreased, and functional connectivity in the right DLPFC, the bilateral cuneus and the right middle cingulate gyrus had increased.Conclusions:Two weeks of intermittent TBS of the right DLPFC can improve the swallowing and cognition of persons with dysphagia. Functional reorganization of brain networks may be one of the neural mechanisms involved.

Objective: To evaluate the motility of the esophagus while swallowing of brainstem stroke survivors. Methods: Eighteen patients and 10 healthy subjects were included in the study. There was no significant difference in average age, gender, weight or body mass index between the two groups. All underwent high-resolution esophageal manometry to assess esophageal motility while swallowing, and they were rated using the version 3.0 of the Chicago classification. Results: Fourteen of the 18 stroke survivors displayed abnormal esophageal dynamics (77.8%), compared with only 10.0% of the healthy control group, but that difference was not statistically significant. The typical abnormalities were a lack of contraction, high pressure contractile esophagus, gastroesophageal junction outflow obstruction and/or distal esophageal spasm. Compared with the control group, the average resting pressure of the patients′ upper esophageal sphincters (UESs) was significantly lower, while the UES residual pressure and integrated relaxation pressure of their lower esophageal sphincters (LESs) were higher and the average UES relaxation time was significantly shorter. No significant differences were found in the LES resting pressures, distal contractile integrals or the distal latency between the two groups. Conclusions Abnormal esophageal motility is highly prevalent in brainstem stroke survivors and due attention should be paid to it. High-resolution manometry can be used to assess this condition.

Objective:To investigate the present situation of delayed medical care for patients with senile cataract and analyze the influencing factors.Methods:Totally 636 senile cataract patients in Baoji Eye Hospital from January to September, 2017 were recruited. They were investigated using the current status of medical delay questionnaire.Results:The detection rate of delayed medical care for elderly patients with cataract was 36.95%(235/650). Logistic analysis demonstrated that significant influencing factors for patient delay included age, place of residence, educational level, hypertension, diabetes, medical insurance, distance and time for place of residence to the nearest medical unit for elderly cataract patients ( P<0.05) . Conclusion:There are widespread medical delays in elderly cataract patients in Baoji City. We should strengthen health education for elderly cataract patients, provide social support, and develop targeted measures to promote timely medical treatment, reduce blindness and increase quality of life.

Objective To explore the effect of applying surface neuromuscular electrical stimulation (NMES) on the functioning of the upper esophageal sphincter (UES) using the high-resolution solid-state manometry.Methods Seventeen healthy volunteers were selected and given sham stimulation (SS),superior and inferior hyoid stimulation (SIHS),superior hyoid stimulation (SHS) or inferior hyoid stimulation (IHS) at a frequency of 80 Hz and the maximum tolerated level before swallowing.Any changes in the kinematics or biomechanics during swallowing and at rest were recorded using high-resolution solid-state manometry.One-factor repeated analysis of the measurement variance was used.Results A significant decrease in the duration of UES relaxation was observed in response to the electrical stimulation (compared with the sham stimulation).The UES's residual pressure showed a rising trend during electrical stimulation,especially in response to IHS,but the difference compared with SS was not significant.The UES's resting pressure during SIHS increased significantly compared with SS,but there was no significant difference between SHS and IHS in this respect.Conclusions Surface neuromuscular electrical stimulation applied to the neck can immediately change the functioning of the UES.NMES at the maximum tolerated intensity can reduce the duration of UES relaxation,which is important for dysphagia therapy and research.
