Objective:To explore the value and clinical significance of percutaneous CO 2 monitoring in non-invasive positive pressureventilator in the treatment of severe obstructive sleep apnea (OSA) in children. Methods:Retrospective analysis was conducted on 38 children with severe OSA, who were treated in Henan Children′s Hospital from August 2023 to December 2024. All of the enrolled children were diagnosed by polysomnography(PSG), treated with non-invasive positive pressure ventilator (NPPV) according to the standard treatment plan, and continuously monitored with TcpCO 2. Arterial blood gas was analyzed before and after pressure titration and TcpCO 2 changes were compared between awake and sleep with arterial blood gas PaCO 2. The sleep parameters, parameters related to arterial blood gas, and the relationship between TcpCO 2 and alveolar hypoventilation in children were analyzed. The cut-off value of alveolar hypoventilation factors were estimated. Statistical analysis was performed using the SPSS 27.0 software. Results:(1)The difference between awake TcpCO 2 and sleep TcpCO 2 was statistically significant[(42.52±3.56)mmHg vs.(51.09±4.07)mmHg, P<0.001), and the difference between sleep TcpCO 2 and morning PaCO 2 was statistically significant[(51.09±4.07)mmHg vs. (40.83±5.34)mmHg, P<0.001]. (2) There was no significant difference in related indicators among different gender children, but the difference in BMI values between preschool and school age children was significant[(18.03±4.96)kg/m 2vs.(25.21±5.25)kg/m 2, t=-4.08, P<0.001]. (3) Obstructive apnea hypopnea index(OAHI), oxygen desaturation index (ODI), and TcpCO 2 were independent risk factors for alveolar hypopnea, but there was no correlation between BMI and whether alveolar hypoventilation.(4).OAHI, ODI, and TcpCO 2 were predictive of the presence of alveolar hypoventilation. When the OAHI exceeded 54.7events/h, ODI exceeded 72.1 events/h, and TcpCO 2 exceeded 56.5 mmHg, the children were more likely to have alveolar hypoventilation. Conclusion:Transcutaneous carbon dioxide, OAHI and ODI can effectively predict whether children have alveolar hypoventilation, which is helpful for clinical treatment.

OBJECTIVE To systematically evaluate the relationship of semaglutide with malignant neoplasms in type 2 diabetes mellitus (T2DM) patients.METHODS Retrieved from the Cochrane Library,PubMed,Embase,ClinicalTrials.gov,CNKI,Wanfang data and CBM,randomized controlled trials (RCTs) about semaglutide in the treatment of T2DM patients with outcome measures including malignant tumor events were collected from the establishment of the database to June 2024.Meta-analysis was performed by using RevMan 5.3 software to assess the risk of malignant neoplasms.RESULTS A total of 24 RCTs (26 trials) involving 24145 patients were included.Results of meta-analysis showed that compared to placebo,there was no statistical significance in the risk of semaglutide in pancreatic cancer[RR=0.39,95％CI(0.10,1.50),P=0.17],thyroid cancer[RR=1.29,95％CI(0.38,4.36),P=0.68],prostate cancer[RR=1.05,95％CI(0.36,3.12),P=0.92],skin cancer[RR=1.27,95％CI(0.80,2.02),P=0.31],gastrointestinal cancer[RR=1.00,95％CI(0.47,2.14),P=1.00],colorectal cancer[RR=0.96,95％CI(0.40,2.26),P=0.92],lung cancer[RR=1.62,95％CI(0.74,3.55),P=0.23],breast cancer[RR=1.25,95％CI(0.45,3.51),P=0.67]or all malignant neoplasms[RR=0.96,95％CI(0.76,1.21),P=0.73].Compared to other antidiabetic drugs,there was no statistical significance in the risk of semaglutide in pancreatic cancer[RR=0.62,95％CI(0.18,2.09),P=0.44],thyroid cancer[RR=1.09,95％CI(0.25,4.78),P=0.90],prostate cancer[RR=2.09,95％CI(0.46,9.47),P=0.34],skin cancer[RR=1.76,95％CI(0.65,4.72),P=0.26],gastrointestinal cancer[RR=0.68,95％CI(0.19,2.35),P=0.54],colorectal cancer[RR=0.60,95％CI(0.20,1.78),P=0.36],lung cancer[RR=1.00,95％CI(0.24,4.11),P=1.00],breast cancer[RR=0.82,95％CI(0.25,2.66),P=0.74]or all malignant neoplasms[RR=1.36,95％CI(0.96,1.94),P=0.09].CONCLUSIONS Semaglutide does not increase the risk of any type of malignant neoplasms in T2DM patients.

Objective:To investigate long-term auditory changes and characteristics of Alport syndrome（AS） patients with different degrees of renal injury. Methods:Retrospectively analyzing clinical data of patients diagnosed AS from January 2007 to September 2022, including renal pathology, genetic detection and hearing examination. A long-term follow-up focusing on hearing and renal function was conducted. Results:This study included 70 AS patients, of which 33（25 males, 8 females, aged 3.4-27.8 years） were followed up, resulting in a loss rate of 52.9%.The follow-up period ranged from 1.1to 15.8 years, with 16 patients followed-up for over 10 years. During the follow-up, 10 patients presenting with hearing abnormalities at the time of diagnosis of AS had progressive hearing loss, and 3 patients with new hearing abnormalities were followed up, which appeared at 5-6 years of disease course. All of which were sensorineural deafness. While only 3 patients with hearing abnormalities among 13 patients received hearing aid intervention. Of these patients,7 developed end-stage renal disease（ESRD）, predominantly males （6/7）. The rate of long-term hearing loss was significantly different between ESRD group and non-ESRD group（P=0.013）. There was no correlation between the progression of renal disease and long-term hearing level（P>0.05）. kidney biopsies from 28 patients revealed varying degrees of podocyte lesion and uneven thickness of basement membrane. The severity of podocyte lesion was correlated with the rate of long-term hearing loss（P=0.048）, and there was no correlation with the severity of hearing loss（P>0.05）. Among 11 cases, theCOL4A5mutationwas most common （8 out of 11）, but there was no significant correlation between the mutation type and hearing phenotype（P>0.05）. Conclusion:AS patients exhibit progressive hearing loss with significant heterogeneity over the long-term.. THearing loss is more likely to occur 5-6 years into the disease course. Hearing abnormalities are closely related to renal disease status, kidney tissue pathology, and gene mutations, emphasizing the need for vigilant long-term hearing follow-up and early intervention.

Objective:To analyze the clinical characteristics, treatment, and prognosis of ectopic bronchogenic cysts in children.Methods:A retrospective analysis was conducted on the data including the clinical characteristics, auxiliary examination and treatment of 21 children with ectopic bronchogenic cysts diagnosed pathologically at Children′s Hospital Affiliated to Zhengzhou University from July 2015 to December 2023. There were 16 males and 5 females, with a male-female ratio of 3.2∶1, and the age ranged from 4 days to 8 years old (median age 2 years and 8 months).Results:Among the 21 cases of ectopic bronchogenic cysts, 11 cases were found in the pharynx, with symptoms including dyspnea (4 cases), snoring during sleep (3 cases), and choking on milk(4 cases).Ten cases were found in the head, neck or anterior chest, 5 of these cases had infection history, and 5 showed progressive mass growth.Imaging and endoscopy showed 9 patients underwent preoperative color ultrasonography revealed cystic masses with well-defined boundaries. CT examination was performed on 13 patients, which showed round or nearly round masses with homogeneous density, smooth margins, and regular cyst walls. CT attenuation values ranged from 2 to 52 Hounsfield Units (HU). Four cystic lesions were assessed via MRI, 3 cases demonstrated long T1 and long T2 signals, while 1 case had a slight short T1 and long T2 signal, with high signal intensity on fat-suppressed images. Eleven cases of pharyngopharyngeal cysts were examined by electronic nasopharyngoscopy. The cysts appeared as spherical or ovoid masses with smooth surfaces, close to or slightly light in color with the surrounding tissue, with one cyst presenting with a bluish blue in the oropharynx. All 11 pharyngeal cysts were excised using low-temperature plasma under general anesthesia and intubation assisted by a nasal endoscope. The cysts were pulled and excised as completely as possible.Ten cases of neck and anterior chest cysts were completely excised. Postoperative histopathology confirmed bronchogenic cyst. Twenty-one children were followed up postoperatively for 4 months to 7 years without recurrence, except for 1 patient who was lost to follow-up.Conclusions:Ectopic bronchogenic cysts are uncommon and lack of typical imaging and clinical features.Combination of ultrasonography, CT and MRI is recommended for cases occuered in neck and anterior chest, while electronic nasopharyngoscopy complements pharyngeal evaluations. Surgical intervention is the preferred treatment choice for this disease.

Objective:To produce 161Tb from enriched 160Gd 2O 3 isotope-enriched target material and realize domestic production of the novel medical isotope 161Tb. Methods:The 160Gd 2O 3 isotope-enriched target material was irradiated with neutrons by the China Mianyang Research Reactor (CMRR). The no-carrier-added 161Tb product was obtained after the processes of target broken, sample dissolution, separation and purification with lanthanide (LN) resin and solution replacement with diglycolamide (DGA) column. Various key indicators such as γ spectral purity, metal impurity content, specific activity, radiochemical purity, and radioactive concentration were used to conduct the quality inspection and the control of 161Tb products. Results:161TbCl 3 of 33.4 GBq was obtained in a single time with the radioactive concentration of 16.8 GBq/ml, nuclear purity more than 99.9%, and radiochemical purity of 99.2%. Metal impurity content was met the established standards, with the specific activity of 6.02×10 17 Bq/mol. The radiochemical purities of 161Tb labeling with 1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid- D-Phe1-Tyr3-Thr8-octreotide (DOTATATE) after 0 and 72 h were 100% and 95.8% respectively. Conclusion:The preparation of no-carrier-added 161Tb by using LN resin has the advantages of high separation performance and high sample loading, which has great significance in the field of medical isotope preparation and lays a good nuclide guarantee for the research and development of domestic 161Tb-labeled drugs.

Objective: To investigate the influence of qigong on late positive potential, which was elicited by affective pictures.Methods: College students who met the inclusion criteria were enrolled and randomly allocated to the qigong group, which received a four-week training (n=41) or the control group (n=41). All participants were assessed before and after the training for event-related potential, which was elicited by negative, neutral, and positive pictures. Electrodes at the centerline position of the frontal area (FCz), parietal area (Pz), and occipital area (Oz) were analyzed. Results: Negative, neutral, and positive pictures demonstrated statistically significant differences on FCz (P<.001), Pz (P<.001), and Oz (P<.001). The interaction between the group factor and time factor was statistically significant on Pz (P =.028). The pairwise comparison of Pz on the time factor and group factor showed that the amplitudes of the qigong group after training were smaller than before (P<.001), and the amplitudes of the control group were not statistically significant (P=.355). Conclusion: Our results supported the conclusion that qigong practices could affect the emotional regulation of college students. Qigong exercise weakens the emotional regulation of late positive po-tential, which is sensitive to top-down affective modulation. The findings imply that the regulating effect of qigong on emotions may be part of the reason why it is effective in reducing depression and anxiety symptoms.

Objective To observe the effect of athletic taping on shoulder subluxation in stroke patients with hemiplegia. Methods From March, 2017 to March, 2018, 40 stroke patients with hemiplegia were randomly divided into control group (n = 20) and experiment group (n = 20). They all accepted routine rehabilitation training, and the experiment group accepted athletic taping before the training. They were measured acromio-humeral distance (AHD) before and after four weeks of treatment. Meanwhile, the were assessed with Visual Analogue Scale (VAS) of pain, simplified Fugl-Meyer Assessment-upper extremity (FMA-UE) and Functional Comprehensive Assessment (FCA). Results AHD, and scores of VAS, FMA-UE and FCA improved in both the groups after treatment (Z > 3.508, t > 4.544, P < 0.001), and improved more in the scores of VAS, FMA-UE and FCA in the experiment group than in the control group (Z = -3.151, t > 2.843, P < 0.01). Conclusion Athletic taping can alleviate shoulder pain, promote upper limb functional recovery and improve the ability of daily living for stroke patients with hemiplegia.
