Objective To investigate the characteristics of attentional control between Wenchuan earthquake anxious and normal children. Methods Using Screening Child Anxiety Related Emotional Disorders (SCARED), 18 earthquake anxious children were chosen as participants and 18 normal children were chosen as control group. They were asked to perform a visual search task. Results ( 1 ) The judgment accuracy of earthquake anxious children was lower than normal children's significantly ( ( 0.95 ± 0.01 ), ( 0. 98 ± 0. 01 ), P ＜0.01 ). ( 2 ) The reaction time of earthquake anxious children was significantly longer than normal children' s ((1664.5 ± 78.5 ) ms, ( 1110.7 ± 78.5 ) ms, P ＜ 0. 01 ). ( 3 ) There was significantly faster performance in the valid condition than in the neutral( ( 1304.7 ± 61.3 ) ms, ( 1382. 3 ± 47.4 ) ms, P ＜ 0. 05 ) and invalid condition ( ((1304.7 ± 61.3 )ms, (1475.8 ± 71.5 )ms; P ＜ 0. 05 ), as well as faster performance in the neutral than in the invalid condition ((1382.3 ± 47.4) ms, ( 1475.8 ± 71.5 ) ms, P ＜ 0.05 ) in all children. Conclusion The performance of earthquake anxious children on top-down attentional control task is less than normal children. It indicates that anxious emotion which is brought by traumatic incidents like earthquake influents earthquake anxious children' s cognitive processing ability.

OBJECTIVE: Aimed to analyse the clinical features of the patients with sphenoid sinus mucocele, achieve earlier diagnosis and more timely intervention and decrease the occurrence of misdiagnoses. METHOD: A retrospective study was first conducted in patients with sphenoid sinus mucoele treated in Xiangya hospital from Jan 2000 to Jan 2015. Then literature reports on this disease were collected and analyzed from China National Knowledge Infrastructure (CNKI) and Wan Fang database. RESULT: We collected 82 patients with sphenoid sinus mucocele treated in Xiangya hospital. There were 52 patients presented with headache, 31 patients presented with visual impairment, 10 patients presented with cranial nerve palsy, 2 patients presented with exophthalmos, 15 patients presented with nasal symptoms, and 5 patients with no obvious symptoms. There was no significant difference for symptoms distribution between male and female patients (P > 0.05). Among 45 patients with headache as first symptom and 10 patients with ethmoid sinus mucocele, there were 18 patients and 8 patients subsequently suffering from visual impairment, respectively. We also collected 161 patients in literature except for enrolling, the 82 patients treated in Xiangya hospital, and found that headache was the most common symptom, followed by visual impairment, in the two independent cohorts. CONCLUSION To the best of our knowledge, this is the study of maximum sample for sphenoid sinus mucocele in China. Headache and visual impairment are the most common symptoms for sphenoid sinus mucocele. Surgical treatment should be early performed when the desease accompanied with headache or ethmoid sinus mucocele, to avoid other complications such as visual impairment and even blindness.

Objective:To investigate the difference of dose distribution between intensity-modulated photon radiotherapy (IMRT) and intensity-modulated proton radiotherapy (IMPT) in patients with non-small cell lung cancer.Methods:The clinical data of 8 patients with stage Ⅱ-Ⅲ non-small cell lung cancer who received radiotherapy in Ion Medical center of the First Affiliated Hospital of University of Science and Technology of China from November 2020 to April 2022 were retrospectively analyzed. IMRT and IMPT radiotherapy plans were created for each patient separately, the main evaluation indicators were targeted area dose distribution parameters [homogeneity index (HI), conformity index (CI) and the percent volume of volume wrapped by 95% and 100% of prescription dose profile in the targeted area (V 95% and V 100%)], and the average dose (D mean) to the organ at risk and the percent volume of a certain relative biological effect (RBE) dose exposure [D mean, V 5 Gy(RBE) and V 20 Gy(RBE) of ipsilateral lung, D mean, V 5 Gy(RBE) and V 20 Gy(RBE) of bilateral lung, D mean, V 30 Gy(RBE) and V 40 Gy(RBE) of heart, maximum dose (D max) of spinal cord, and D mean of esophageal]. Results:In comparison with IMRT, IMPT reduced the levels of dose parameters in bilateral lung, ipsilateral lung, spinal cord, esophagus, and heart with statistically significant differences (all P < 0.05), especially in D mean of bilateral lung [(4.1±1.8) Gy (RBE) vs. (6.9±1.9) Gy (RBE)], V 5 Gy(RBE) [(15.9±7.1) % vs. (28.5±8.6)%], V 20 Gy(RBE) [(7.4±3.5)% vs. (10.1±3.5)%], and D mean of ipsilateral lung [(9.1±4.5) Gy (RBE) vs. (11.9±3.3) Gy (RBE)], all decreased significantly (all P < 0.001), but the differences in the levels of targeted area dose distribution parameters between them were not statistically significant (all P > 0.05). Conclusions:For patients with non-small cell lung cancer, IMPT is superior to IMRT in the protection of bilateral lung, ipsilateral lung, spinal cord, esophagus and heart.

Objective To explore the automated identification and diameter measurement methods for inferior vena cava (IVC) based on clinical ultrasound images of IVC. Methods An automated identification and localization method based on topology and automatic tracking algorithm was proposed. Tracking algorithm was used for identifying and continuously locating to improve the efficiency and accuracy of measurement.

Results The recognition accuracy of the automated method was 94.44％ (17/18),and the measurement error of IVC diameter was within the range of±1.96s (s was the standard deviation). The automated method could replace the manual method. Conclusion The proposed IVC automated identification and localization algorithm based on topology and automatic tracking algorithm has high recognition success rate and IVC diameter measurement accuracy. It can assist clinicians in identifying and locating IVC,so as to improve the accuracy of IVC measurement.

Background::Dermatophagoides pteronyssinus is a common allergen causing allergic diseases in China. The aim of this study was to evaluate the efficacy and safety of D. pteronyssinus extracts produced by Peking Union Medical College Hospital (PUMCH) for the skin prick test (SPT) in the diagnosis of D. pteronyssinus allergy. Methods::A total of 910 subjects with allergic diseases were prescribed D. pteronyssinus SPT and specific sIgE (sIgE) test among the Outpatients of Department of Allergy, PUMCH from August 10, 2015 to August 30, 2017. Receiver operating characteristic curve (ROC) analysis was performed according to the results of D. pteronyssinus-sIgE detection. The accuracy of D. pteronyssinus extracts used for SPT in the diagnosis of D. pteronyssinus allergy was evaluated under different cutoff values. Adverse events after SPT were recorded to evaluate safety. Results::There were 796 and 618 subjects in the full analysis set (FAS) and the per protocol set (PPS), respectively. The areas under the curve of FAS and PPS were 0.871 and 0.873, respectively. According to the ROC of PPS, the optimal and 95% specificity diagnostic cutoff values of D. pteronyssinus SPT mean wheal diameter were 3.25 and 3.75 mm, respectively. No adverse events occurred. Conclusion::The extracts of D. pteronyssinus for SPT were simple, highly accurate, and safe and should be considered for recommendation in the clinical diagnosis of D. pteronyssinus allergy.
