Objective: To analyze the relationship of gross motor skills and perceptual motor abilities with physical activity levels in preschool children in a Beijing kindergarten, so as to provide a reference for promoting the development of motor competence. Methods: From September 2018 to March 2021, preschoolers aged 4-5 years were selected using convenience sampling method from an urban kindergarten in Beijing. The Test of Gross Motor Development-Third Version(TGMD-3) was used to assess basic preschoolers s gross motor skills ( n =152). The Pictorial Scale of Perceived Movement Skill Competence(PMSC) was used to evaluate perceptual motor skills ( n =151). Accelerometers (Actigraph GT3X) were used to record physical activity levels ( n =52). Data were analyzed using one way analysis of variance (ANOVA) and Pearson correlation coefficients. Results: The mean scores for gross motor skills and perceptual motor abilities were (38.76±13.48) and (35.49±6.50), respectively. The moderate to vigorous physical activity(MVPA) level was(52.60±27.44) minutes per day. No statistically significant correlations were found between gross motor skills, perceptual motor abilities MVPA among boys, girls or the overall group ( r =-0.20 to 0.25, all P >0.05). However, Boys locomotor skills, overall children s locomotor skills, and boys gross motor skills were all positively correlated with MVPA( r =0.34-0.45, all P <0.05). Conclusion There is a correlation between locomotor skills and physical activity levels in 4 to 5-year-old children.

Objective To explore the correlations between serum Mas-related G protein-coupled receptor X2 (MRGPRX2), interleukin (IL)-4, IL-5, IL-6, IL-13, IL-23 and IL-33 levels and chronic spontaneous urticaria (CSU). Methods The clinical characteristics and laboratory data from 55 patients with CSU and 21 healthy controls at Huashan Hospital, Fudan University from February 2021 to September 2023 were collected. The disease activity and severity of CSU patients were assessed. Serum level of MRGPRX2 was tested using enzyme-linked immunosorbent assay (ELISA), and levels of IL-4, IL-5, IL-6, IL-13, IL-23, and IL-33 were measured using Luminex multiplex assay in all subjects. Spearman correlation analysis was used to evaluate the correlations between biomarkers and other parameters in CSU patients, and logistic regression analysis was performed to identify factors influencing CSU. Results CSU patients exhibited significantly higher serum levels of MRGPRX2 (2.41[0, 11.51] ng/mL vs 0[0, 2.86] ng/mL, P＝0.015) and IL-23 (0.09[0.04, 0.56] pg/mL vs 0.05[0.03, 0.08] pg/mL, P＝0.033) than healthy controls. There was no difference in levels of other cytokines between the two groups. There was no difference in levels of MRGPRX2 and cytokines between severe and non-severe CSU patients. Correlation analysis showed that serum MRGPRX2 levels in CSU patients were positively correlated with IL-4 (r＝0.345, P＝0.010) and IL-6 (r＝0.395, P＝0.003) levels. Logistic regression analysis indicated that MRGPRX2≥0.055 ng/mL and IL-23≥0.135 pg/mL were independent risk factors for CSU (P＜0.05). Conclusions Serum levels of MRGPRX2 and IL-23 in CSU patients are elevated, which may be involved in the pathogenesis of CSU.

Objective:To investigate the clinical benefit and application value of the Da Vinci robotic surgical system through bilateral axillary areolar approach in cervical lymph node dissection in obese thyroid carcinoma patients.Methods:The clinical data of 117 patients with thyroid cancer admitted to the thyroid and breast surgery Department of the 960th Hospital of the Chinese PLA Joint Logistic Support Force from January 2018 to June 2023 were retrospectively analyzed. There were 55 males and 62 females, aged from 17 to 64 years, with an average age of (36.05±8.77) years. According to body mass index (BMI), patients were divided into normal group (18.5 kg/m 2≤BMI< 24 kg/m 2, n=60) and obese group (BMI≥28 kg/m 2, n=57). Gender, age, BMI, operation time, postoperative drainage fluid volume, tumor diameter, central lymph node dissection and number of metastasis, cervical lymph node dissection and number of metastasis, postoperative hospital stay, postoperative aesthetic satisfaction score and surgical complications of the two groups were analyzed. SPSS 26.0 statistical software was used to analyze the data. Results:All of patients completed the operation successfully, and neither group was transferred to open surgery. The BMI of obese group was higher than that of normal group [(31.35±3.08) kg/m 2vs (22.53±0.82) kg/m 2, t=20.97, P<0.05]. The maximum tumor diameter in the obese group was greater than that in the normal group [(13.81±10.70) mm vs (10.42±5.53) mm, t=2.17, P<0.05]. There were no significant differences in operation time, number of central lymph node dissection and metastasis, number of cervical lymph node dissection and metastasis and postoperative complications between the two groups ( P>0.05). Conclusions:Utilization of the Da Vinci robotic surgical system via the BABA approach demonstrates both safety and feasibility in obese patients with thyroid carcinoma undergoing lateral cervical lymph node dissection. Importantly, this technique does not increase the risk of surgical complications, thus providing a novel alternative for lateral cervical lymph node dissection in obese thyroid carcinoma patients.

Objective:To explore risk factors of early acute kidney injury (AKI) after pediatric living donor liver transplantation (LT) and examine the effects on the prognosis of recipients.Methods:From January 2018 to December 2019, the relevant clinical data were retrospectively reviewed for 201 pediatric recipients of elective living donor LT. Post-LT AKI recipients were diagnosed and categorized according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria (2012). Based upon the presence or absence of AKI within 7 days post-LT, they were assigned into two groups of AKI (64 cases) and non-AKI (137 cases). Baseline profiles, preoperative results of major laboratory tests and operation-related parameters were compared between two groups. Univariate variables with statistical differences were included into binary Logistic regression model for multivariate analysis to identify the independent risk factors of early AKI post-LT. Prognostic data of recipients such as postoperative mechanical ventilation time, intensive care unit (ICU) stay time, total hospitalization stay, in-hospital mortality and 3-year postoperative mortality were compared between two groups. Survival analysis was conducted for pediatric recipients with different AKI grades.Results:The incidence of AKI within 7 days post-LT was 31.8% (64/201). Univariate analysis revealed significant inter-group differences in age, preoperative PELD score, diagnosis of biliary atresia, total bilirubin, cystatin C, operative duration and volume of blood loss ( P<0.001, P<0.001, P=0.002, P<0.001, P<0.001, P<0.001& P<0.001). Multi-factorial analysis showed that total bilirubin ( OR=1.154, 95% CI: 1.068-1.248, P<0.001), cystatin C ( OR=2.532, 95 % CI: 1. 627-3.939, P<0.001), operative duration ( OR=1.174, 95% CI : 1.064-1.295, P=0.001) and volume of blood loss ( OR=1.210, 95% CI : 1. 095-1.337, P<0.001) were independent risk factors of AKI within 7 days post-LT. As compared with non-AKI group, postoperative mechanical ventilation time and ICU stay time became markedly extended (178 vs 389 min, P<0.001 ; 2 vs 3 day, P<0.001) and mortality during hospitalization rose sharply (0.7% vs 7.8%, P=0.002) in AKI group. The survival rates of recipients during hospitalization in group non-AKI/AKI were 99.3% (136/137) and 96.8% (30/31, grade 1), 92.9 % (13/14, grade 2), 78.9% (15/19, grade 3 ). The survival rates of recipients 3 years post-LT in group non-AKI/AKI were 94.2% (129/137) and 96.8% (30/31, grade 1), 78.6% (11/14, grade 2), 73.7% (14/19, grade 3). Results of survival analysis indicated that, in group non-AKI and AKI (geade 1, 2, 3), survival rate of recipients during hospitalization and 3 years post-LT declined gradually ( χ2=21.102, P<0.001 ; χ2=13.316, P=0.004) . Conclusion:As one common complication after pediatric living donor LT, AKI adversely affects the prognosis of recipients. Elevated preoperative levels of total bilirubin and cystatin C, prolonged operative duration and greater volume of intraoperative blood loss may boost the postoperative risk of early AKI in pediatric recipients.

Objective:To compare the efficacy and safety between WangShiBaoChiWan and mosapride in the treatment of functional dyspepsia (FD).Methods:From September 2019 to September 2020, patients with postprandial fullness and early satiation who met the Rome Ⅳ criteria for FD diagnosis were enrolled from 15 hospitals, including the First Affiliated Hospital of Naval Medical University (Shanghai Changhai Hospital), Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical College. The subjects were randomly divided into WangShiBaoChiWan (experimental) group and mosapride (control) group in the ratio of 1∶1. The treatment regimens were WangShiBaoChiWan+ mosapride simulator, WangShiBaoChiWan simulator+ mosapride, respectively with a treatment period of 2 weeks. The primary efficacy outcome was the improvement rates of main symptoms before and after treatment, the secondary efficacy primary efficacy outcome was the total clinical effective rate and the change of the single symptom score. And the safety indicator included adverse events. Independent sample t-test, paired t-test and chi-square test were used for statistical analysis. Results:A total of 251 FD patients were enrolled in the full analysis set, including 124 in the experimental group and 127 in the control group; 241 FD patients were in the per-protocol analysis set, including 117 in the experimental group and 124 in the control group. The analysis of per-protocol analysis set showed that the improvement rates of the main symptoms of the experimental group and the control group were (66±29)% and (60±30)%, respectively, and the difference was not statistically significant ( P>0.05). The improvement rate of the main symptoms of the experimental group reached 117% of that of the control group, which exceeded the expected non-inferiority standard of 80%. The total clinical effective rates of the experimental group and the control group were 76.07% (89/117) and 75.81% (94/124), respectively, and the difference was not statistically significant ( P>0.05). The results of full analysis set showed that the incidence of adverse events of the experimental group and the control group was 1.62% (2/124) and 1.57% (2/127), respectively, and the difference was not statistically significant ( P>0.05). There were no serious adverse events in the two groups. Conclusion:The improvement rate of the main symptoms of WangShiBaoChiWan is not inferior to that of mosapride in the treatment of FD, and it has good safety.

Objective:To explore the risk factors affecting central lymph node metastasis in cN0 isthmus papillary thyroid carcinoma and the significance and feasibility of preventive dissection, so as to provide reference for clinical treatment.Methods:The clinical data of 108 patients with cN0 stage isthmus papillary thyroid cancer who underwent surgery in the General Surgery Department of Lianyungang Oriental Hospital from January 2014 to December 2021 were retrospectively analyzed. There were 32 males and 76 females, with an age range of 24 to 70 years, with a mean age of (46.0±12.7) years. Statistical analysis was performed using the SPSS 22.0 statistical software. Chi-square test and logistic regression were used to analyze the relationship between central lymph node metastasis and patients Relationship between clinical case factors.Explore the feasibility of preventive cleaning.Results:The positive rate of lymph node metastasis in central region of isthmic papillary thyroid carcinoma was 37.9% (41/108). Univariate analysis showed that central lymph node metastasis was associated with tumor diameter ( χ2=5.36, P=0.021), capsular infiltration ( χ2=7.69, P=0.006), and elevated thyroglobulin ( χ2=7.73, P=0.005). Multivariate analysis showed that capsular infiltration ( HR=2.75, P=0.037) and tumor diameter ( HR=4.454, P=0.004) were independent risk factors for central lymph node metastasis. The ROC curve of tumor diameter to predict central lymph node metastasis was drawn, and the AUC value of the area under the curve was calculated to be 0.720. When the diameter was 0.695 cm, the Youden index was 0.326, the sensitivity was 0.878, and the specificity was 0.448. 6 cases (5.56%) had temporary recurrent laryngeal nerve palsy, 13 cases (12.04%) had temporary hypoparathyroidism, no permanent complications occurred. Conclusions:cN0 stage PTCI has the risk of early occult lymph node metastasis. Prophylactic CLND can clarify the stage of the tumor, assess the risk, and guide the follow-up treatment of patients. CLND should be routinely performed for patients with tumor diameter >0.695 cm and capsular invasion.

Focal cortical dysplasia (FCD) is one of the most common causes of drug-resistant epilepsy. Dysmorphic neurons are the major histopathological feature of type II FCD, but their role in seizure genesis in FCD is unclear. Here we performed whole-cell patch-clamp recording and morphological reconstruction of cortical principal neurons in postsurgical brain tissue from drug-resistant epilepsy patients. Quantitative analyses revealed distinct morphological and electrophysiological characteristics of the upper layer dysmorphic neurons in type II FCD, including an enlarged soma, aberrant dendritic arbors, increased current injection for rheobase action potential firing, and reduced action potential firing frequency. Intriguingly, the upper layer dysmorphic neurons received decreased glutamatergic and increased GABAergic synaptic inputs that were coupled with upregulation of the Na⁺-K⁺-Cl^- cotransporter. In addition, we found a depolarizing shift of the GABA reversal potential in the CamKII-cre::PTEN^flox/flox mouse model of drug-resistant epilepsy, suggesting that enhanced GABAergic inputs might depolarize dysmorphic neurons. Thus, imbalance of synaptic excitation and inhibition of dysmorphic neurons may contribute to seizure genesis in type II FCD.

Background::The pharmacokinetic and clinical behaviors of many proton pump inhibitors (PPIs) in peptic ulcer treatment are altered by CYP2C19 genetic polymorphisms. This non-inferiority study evaluated the efficacy and safety of the novel PPI anaprazole compared with rabeprazole. We also explored the influence of Helicobacter pylori ( H. pylori) infection status and CYP2C19 polymorphism on anaprazole. Methods::In this multicenter, randomized, double-blind, double-dummy, positive-drug parallel-controlled, phase III study, Chinese patients with duodenal ulcers were randomized 1:1 to receive rabeprazole 10 mg + anaprazole placebo or rabeprazole placebo + anaprazole 20 mg once daily for 4 weeks. The primary efficacy endpoint was the 4-week ulcer healing rate assessed by blinded independent review. Secondary endpoints were the proportion of patients with improved overall and individual duodenal ulcer symptoms at 4 weeks. Furthermore, exploratory subgroup analysis of the primary endpoint by H. pylori status and CYP2C19 polymorphism was conducted. Adverse events were monitored for safety. Non-inferiority analysis was conducted for the primary endpoint. Results::The study enrolled 448 patients (anaprazole, n = 225; rabeprazole, n = 223). The 4-week healing rates were 90.9% and 93.7% for anaprazole and rabeprazole, respectively (difference, -2.8% [95% confidence interval, -7.7%, 2.2%]), demonstrating non-inferiority of anaprazole to rabeprazole. Overall duodenal ulcer symptoms improved in 90.9% and 92.5% of patients, respectively. Improvement rates of individual symptoms were similar between the groups. Healing rates did not significantly differ by H. pylori status or CYP2C19 genotype for either treatment group. The incidence of treatment-emergent adverse events was similar for anaprazole (72/220, 32.7%) and rabeprazole (84/219, 38.4%). Conclusions::The efficacy of anaprazole is non-inferior to that of rabeprazole in Chinese patients with duodenal ulcers.Registration::ClinicalTrials.gov, NCT04215653.

Based on binocular disparity, three-dimensional (3D) display technology makes the right and left eyes see different images in a certain way, which generates a stereo image after the processing of the brain's visual cortex.Due to its high-definition stereoscopic surgical field of vision and accurate spatial positioning ability, 3D display technology has been widely used in surgery.Ophthalmic microsurgery is performed with the help of microscope because of the complex intraocular operation and small operating space, especially minimally invasive vitreoretinal surgery, which is the most difficult surgery with the longest learning curve in ophthalmology.The 3D display viewing system can improve surgical accuracy, reduce retinal phototoxicity, relieve the pressure on the neck and back of the surgeon as well as promote communication and cooperation between medical staff and so on.At present, the major 3D display systems applied in ophthalmology include the NGENUITY 3D Visualization System and TrueVision 3D Visualization System, both of which require wearing 3D glasses.The naked eye 3D display system is the main direction of future development.The combination of 3D display system and ophthalmic surgical robot system provides a new idea for the development of remote ophthalmic surgery.At the same time, broader application of 3D display system requires continuous improvement.In this article, the research and application of 3D display system in anterior segment surgery and vitreoretinal surgery were reviewed.
