ABSTRACT

Objective To explore the characteristics of blood uric acid levels and its correlation with calcium and phosphorus levels, and glucose and lipid metabolism in obese adolescents in weight-loss training camps. Methods In this study, 357 obese adolescents aged 12-18 were selected as the research subjects, and 135 normal-weight adolescents were selected as the controls. The body shape and blood uric acid characteristics of the subjects were measured and analyzed. Further, 59 subjects were selected from the obese adolescents for blood calcium, blood phosphorus and glucose and lipid metabolism index tests to analyze the correlation between blood uric acid level and calcium, phosphorus, and glucose and lipid metabolism indicators. Results The average blood uric acid level of obese adolescents was (527.12±122.94)μmol/L, (566.58±122.51)μmol/L for boys, and (468.35±97.79)μmol/L for girls. The blood uric acid level of the obesity group was significantly higher than that of the control group (P<0.001 for boys, P<0.05 for girls), and it was higher in boys than in girls (P<0.01). Obese adolescents with high uric acid accounted for 73.39%. The HOMA-IR of obese adolescents was 5.79±3.04. The blood uric acid level was significantly correlated with blood calcium, total cholesterol, and low-density lipoprotein cholesterol (P<0.05). Gender and low-density lipoprotein cholesterol were the main influencing factors of blood uric acid (P<0.05). Conclusion Obese adolescents have high blood uric acid levels, low calcium and high phosphorus in the body, and a higher incidence of insulin resistance. There exists a positive correlation between the blood uric acid level and the body's calcium and phosphorus metabolism and glucose and lipid metabolism in obese adolescents. Clinical monitoring of lipid metabolism indicators such as low-density lipoprotein has certain reference value for the prevention and treatment of hyperuricemia.

ABSTRACT

Objective:To detect the levels of vascular endothelial growth factor (VEGF) and nitric oxide (NO) in the serum of patients with early diabetic retinopathy (DR) and to explore their value in the treatment of DR.Methods:Fifty-nine patients with type 2 diabetes mellitus from March 2019 to June 2020 in the Yulin Second Hospital were collected and divided into the non-diabetic retinopathy (NDR) group (32 cases) and background stage diabetic retinopathy (BDR) group (27 cases) according to the DR grading criteria, and 29 healthy subjects were enrolled in the healthy control (HC) group. Serum VEGF levels were measured by a double antibody sandwich enzyme-linked immunosorbent assay (ELISA), and serum NO levels were measured by the nitrate reductase method (one-step method). Pearson analysis was used to correlate serum VEGF with NO levels in each group, and a logistic regression model was used to analyze the risk factors for DR.Results:Compared with the HC group, the differences in serum VEGF and NO levels of patients in the BDR group were statistically significant (all P < 0.05). The serum VEGF and NO levels were positively correlated in all groups (all P < 0.01). Duration of diabetes, smoking, glycated hemoglobin A1c (HbA1c), serum VEGF, and NO levels were high risk factors for DR. Conclusions:Serum VEGF and NO levels may be potential pathological mechanisms for the development of microvascular complications in patients with type 2 diabetes, and the interaction may induce or accelerate the progression of DR. This study is expected to provide a new idea of complementary or combined treatment in the treatment of DR.

ABSTRACT

Objective:To investigate the efficacy and safety of sindilizumab combined with apatinib in the treatment of elderly patients with advanced recurrent and metastatic esophageal squamous cell carcinoma.Methods:A total of 74 elderly patients with recurrent and metastatic esophageal squamous cell carcinoma who were admitted to Xuancheng City Central Hospital from March 2019 to August 2020 were selected, and they were divided into study group and control group by random number table method, with 37 cases in each group. The control group was treated with apatinib mesylate, and the study group was treated with sindilizumab combined with apatinib mesylate. All patients were treated for 2 cycles and followed up for 1 year. The efficacy, peripheral blood tumor marker levels, adverse reactions and survival were compared between the two groups.Results:The objective response rate and clinical control rate in the study group were higher than those in the control group [35.1% (13/37) vs. 13.5% (5/37), 67.6% (25/37) vs. 43.2% (16/37)], and the differences were statistically significant ( χ2 = 4.70, P = 0.030; χ2 = 4.43, P = 0.035). After treatment, the levels of carcinoembryonic antigen (CEA), squamous cell carcinoma-associated antigen (SCC-Ag) and cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) in the two groups were all lower than those before treatment (all P < 0.05); the levels of CEA, SCC-Ag and CYFRA21-1 in the study group were lower than those in the control group (all P < 0.05). There were no differences in the incidence rates of fatigue, proteinuria, bone marrow suppression, and hand-foot syndrome between the two groups (all P > 0.05). After 1 year of follow-up, 20 patients in the study group survived, and the 1-year overall survival (OS) rate was 54.1%; 10 patients in the control group survived, and the 1-year OS rate was 28.6%; the difference in OS between the two groups was statistically significant ( χ2 = 4.06, P = 0.044). Conclusions:Sintilimab combined with apatinib has a good efficacy in the treatment of elderly patients with advanced recurrent and metastatic esophageal squamous cell carcinoma. This regimen can reduce the levels of tumor markers, improve the short-term survival rate of patients, and has good safety.

ABSTRACT

Objective To study mechanical properties of the novel micro-movement elastic implant of distal tibiofibular syndesmosis in dorsiflexion position.Methods A combination of simulation and experiment was used. The normal ankle dorsiflexion model, the bone nail repaired model and the micro-movement elastic implant repaired model were established by using Mimics and CT data. Besides, ANSYS Workbench was used for finite element analysis. Mechanical experiments on lower limb specimens were conducted on Instron E10000 mechanical test instrument, and five sets of experimental data were measured and analyzed.Results Mechanical properties of the micro-movement elastic implant repaired model were closer to those of the normal ankle dorsiflexion model, but stress of the micro-movement elastic implant repaired mode was greater than that of the bone nail repaired model. The results of two-sample heteroscedasticity t test indicated that there was no significant difference in resistance torque between the micro-movement elastic implant repaired model and the normal ankle dorsiflexion model.Conclusions For dorsiflexion position, repairing mechanical properties of the novel micro-movement elastic implant are much better than those of the bone nail, and there is still room for optimizing the micro-movement elastic implant.

ABSTRACT

【Objective】 To understand the structural characteristics of lapsed apheresis donors in our blood center and provide guidance for further improving recruitment and retention strategies by retrospectively analyzing the characteristics of lapsed apheresis donors in our center in recent years. 【Methods】 The apheresis donation and lapsed apheresis donors in Zhejiang Blood Center from 2016 to 2020 were statistically analyzed, and the general information of lapsed donors, including gender, blood type, age, education level and occupation composition, were compared and analyzed. The lapse of novel and long-term donors with different frequency were retrospectively analyzed. The SPSS 19.0 statistical software package was used for data analysis. 【Results】 In 2020, the total lapse of apheresis donors decreased by 16.6% as compared with 2016(P<0.05). The lapse rate of donors with blood groups A, B, O and AB was 1∶1∶1∶1, higher in female donors(59.0%) than males(50.0%), and dominated by age group of 18-35(66.3%). With the increase of age, the lapse rate decreased. Donors lapsed were mainly with college or above educational background(60.8%), with high proportion in students and the staff. In 2020, the lapse of novel apheresis donors decreased by 34.1% as compared with 2016, but the average lapse rate of novel apheresis donors was still as high as 70.5%. The average lapse rate of blood donors with different frequency was 52.5%, and the lapse rate decreased significantly with the increase of apheresis donation frequency. The average lapse rate of novel blood donors with whole blood donation experience was lower than those without (56.1% vs 82.9%). 【Conclusion】 Multiple measures for recruitment and retention have effectively reduced the lapse of apheresis donors. However, apheresis donors who are 18-35 years old, with college degree or above, students and staff were the main groups from lapsing. In addition, low-frequency and novel apheresis donors without whole blood donation experience were more likely to be lapsing. Targeted and personalized blood donation services should be further provided, and the management of " full cycle of blood donation" should be strengthened to reduce the lapsing, so as to retain more blood donors.

ABSTRACT

Objective:To compare the differences in exploratory behaviors between infants with high-risk autism spectrum disorder (HR-ASD) and normal development (TD) infants, and to explore the relationship between exploratory behaviors and the severity of ASD symptoms.Methods:A total of 31 infants aged 6-23 months with HR-ASD in the Pediatric Clinic, the Affiliated Brain Hospital of Nanjing Medical University from January 2019 to August 2020 were retrospectively recruited in the HR-ASD group, and 37 TD infants aged from 6 to 23 months in Nanjing were selected as the TD group.The development level of the 2 groups was evaluated by Gesell development scale, and the depth and breadth of exploratory behaviors were measured in free play.Autism Diagnostic Observation Schedule (ADOS) was used to evaluate the severity of ASD symptoms in HR-ASD group.Differences in exploratory behaviors between the 2 groups were analyzed by the independent sample t-test and Chi- square test. Pearson′ s correlation analysis was performed to explore the correlation between exploratory behaviors and symptom severity in HR-ASD group.Binary Logistic regression analysis was used to explore the discrimination efficiency of sexual behavior in the 2 groups. Results:Compared with TD group, the depth and breadth of exploratory behaviors in HR-ASD group were significantly lower (55.06±25.73 vs.132.78±44.69, 4.42±2.20 vs.8.78±3.28)( t=-8.95, -6.53, all P<0.01), and atypical exploratory behavior and avoidance withdrawal behavior were significantly worse [18 cases(58.06%) vs.6 cases(16.22%), 10 cases(32.26%) vs.3 cases(8.11%)]( χ2=15.30, 6.36, all P<0.05). Significant differences in the frequency and duration of object exploration, environmental exploration and social exploration were detected between HR-ASD group and TD group (3 vs. 0 vs. 0, 45 vs. 0 vs. 0)(all P<0.01). Pearson correlation analysis showed that, the frequency of object exploratory behavior was positively correlated with the dimension of ADOS in HR-AD group ( r=0.40, P<0.05); while the duration of object exploratory behavior, the complexity of object explo-ratory behavior and the depth of exploratory behavior were negatively correlated with CARS score ( r=-0.45, -0.47, -0.42, all P<0.05). The depth of exploratory behavior was negatively correlated with the stereotyped dimension of ADOS ( r=-0.40, P<0.05). Binary Logistic regression analysis showed that the depth of exploratory behavior had a discrimination effect ( P<0.01). Conclusions:The characteristics of exploratory behaviors in HR-ASD infants are abnormal, especially the distinguishing effect on the depth of exploratory behaviors, which can be used as a candidate behavioral index for early screening of ASD.

ABSTRACT

Objective:To determine the mechanical properties of our self-designed novel cross-locking intramedullary nails and the impact of number of conical locking nails on the fixation through a finite element analysis and specimen experiments.Methods:Mimics 19.0 and SolidWorks 2014 were used to create transverse fracture models of the olecranon which were subjected to fixation with respectively K-wire tension band (KTB) and our self-designed novel cross-locking intramedullary nails (NIN). The strengths of KTB and NIN fixation were analyzed by Ansys. Fifteen human ulna specimens were used to construct a transverse fracture model of the olecranon; an Instron E10000 mechanical testing machine was used to determine mechanical properties in fixation respectively with KTB, one NIN (NIN-1) and 3 NINs (NIN-3).Results:In the finite element analysis, in simulation of the forearm flexed at 45° under a 100 N load, the deformation of the fracture surface of the olecranon in fixation with KTB, NIN-1 and NIN-3 was respectively 0.131 mm, 0.123 mm and 0.121 mm. In the specimen experiments, in simulation of the forearm flexed at 45°, the maximum failure loads for fixation with KTB, NIN-1 and NIN-3 were (313.38±27.68) N, (528.56±53.58) N and (871.04±94.95) N, respectively, showing significant differences among the 3 groups ( P<0.05). The maximum failure load for NIN-3 fixation was significantly greater than that for KTB or NIN-1 fixation, and the maximum failure load for NIN-1 fixation was significantly greater than that for KTB fixation ( P<0.05). Conclusions:Compared with KTB fixation, NIN fixation is more convenient in operation and has better mechanical properties. NIN-3 fixation has the best mechanical properties.

ABSTRACT

Autoimmune hepatitis (AIH) is a chronic progressive inflammatory disease of the liver caused by the attack of liver cells by the autoimmune system, with the features of positive serum autoantibodies, high IgG, and/or γ-globulinemia. Current studies on pregnancy in patients with AIH mainly focus on labor complications, and there is still a lack of systematic recommendations for the evaluation, treatment, and management of diseases in the progestational stage, during pregnancy, and after delivery. Although immunity is suppressed during pregnancy, poor disease control within one year before pregnancy and spontaneous drug withdrawal during pregnancy can significantly increase adverse pregnancy outcomes. Therefore, this article describes how to implement multidisciplinary collaboration and management of the whole cycle of pregnancy, so as to improve maternal and fetal safety.

ABSTRACT

【Objective】 To discuss the prevention and control strategies of physical examination and health consultation for apheresis donation during the COVID-19 outbreak, and to verify its necessity and efficiency. 【Methods】 A three-stage (Hubei import period, Jan 23 to 31; local(Zhejiang) epidemic period( Feb 1 to Mar 1); overseas import period, Mar 2 to 22) prevention and control strategy for physical examination and health consultation during the COVID-19 outbreak from January 23 to March 22, 2020 was adopted by our center, and the consultation of residence history, contact history, and the investigation of related symptoms were added to health consultation.The deferral rates of health consultation and physical examination during the COVID-19 outbreak were compared with the same period in 2019. The deferral rates in each stage were compared, containing those contributed by first-time and regular apheresis donors. 【Results】 The deferral rates of health consultation during the epidemic period and the same period in 2019 were 2.31%(100/4 371) vs 1.62%(78/4 740) (P0.05) The deferral rate of travel contact history was the highest at 2.05%(40/1947)during local epidemic period, and respiratory symptoms at 1.29%(5/388)during Hubei import period. The deferral rates of blood pressure during the three stages were1.85%(7/378)vs 3.57%(67/1877)vs 4.08(82/2009)(P>0.05). The deferral rate of health consultation and physical examination in first-time and regular apheresis donors were 5.86%(38/649)vs 1.65%(61/3 696)and 5.79%(35/604)vs 3.41%(124/3 635)(P<0.01). 【Conclusion】 The deferral rates of health consultation and physical examination increased significantly during the COVID-19 epidemic. Therefore, it is necessary to formulate and adopt a targeted consultation strategy during the epidemic period to block COVID-19 transmission to the greatest extent.

ABSTRACT

【Objective】 To develop and implement a precise and efficient telephone recruitment strategy for apheresis platelet donors based on the information management of blood collection and supply process. 【Methods】 A telephone recruitment strategy based on the whole process information management of apheresis platelet donors (hereinafter referred to as telephone recruitment) was formulated From January 1, 2019, apheresis platelet donors in Hangzhou, registered in the intelligent blood donor recruitment system(hereinafter referred to as the recruitment system), were recruited by telephone calls or (and) SMS reminders to inform re-donation interval, key points of recruitment consultation, blood donation appointment time and other precautions. Response rate, pass rate and blood donation rate of donors before(in 2018) and after( in 2019) the implementation of telephone recruitment, as well as the above three rates during the COVID-19 epidemic in 2020 in Hangzhou were collected and analyzed by χ2 test. 【Results】 The response rate, pass rate, and blood donation rate of apheresis platelet donors in Hangzhou before /after the implementation of telephone recruitment and during the COVID-19 epidemic were 28.52%(3 901/13 678)vs 30.52%(4 429/14 511)vs 39.36%(4 064/10 326), 73.80%(2 879/3 901)vs 77.83%(3 447/4 429)vs 78.20%(3 178/4 064)and 6.77%(2 879/42 553)vs 7.77%(3 447/44 366)vs 8.13%(3 178/39 077, respectively(P<0.05). In 2020, 85.94%(3 178/3 698) of apheresis donors were recruited by telephone(P<0.05). The proportion of apheresis donations successfully recruited by telephone in 2018 and 2019 accounted for 11.74% (2 879/24 519) and 12.48% (3 447/27 628), respectively(P<0.05), contributing 10.59% (4 030 U/38 040 U) and 11.38% (4 875 U/42 853 U) of units(P<0.05) that issued to the clinical. Due to the COVID-19 epidemic, the number of blood donors recruited by telephone and its proportion in 2020 decreased significantly as compared with those before the implementation of telephone recruitment (2019). 【Conclusion】 The telephone recruitment strategy based on the whole-process information management (system) of blood collection and supply can effectively improve the targeted recruitment of apheresis platelet donors and enhance its proportion of apheresis collection that issued to the clinical.

ABSTRACT

Objective:To analyze the epidemiological characteristics and trend of human brucellosis in Jinan City of Shandong Province from 2010 to 2019, so as to provide a scientific basis for improving prevention and control strategies and measures.Methods:The brucellosis surveillance data of Jinan City from 2010 to 2019 were obtained from the "Infectious Disease Surveillance System" in "China Information System of Disease Prevention and Control". Descriptive epidemiological methods were used to analyze the epidemiological situation and the three distributions (regional distribution, time distribution, population distribution) of cases.Results:A total of 1 882 cases of brucellosis were reported from 2010 to 2019, with an average incidence rate of 2.64/100 000. The incidence of brucellosis increased from 0.13/100 000 to 5.37/100 000, and reported incidence of brucellosis showed a increasing trend (χ 2trend=307.50, P<0.05). The epidemic areas were spread from 7 towns (streets) of 3 counties (districts) to 76 towns (streets) of 12 counties (districts). The cases were reported each month throughout the year with incidence peak period form April to July. The gender of the patients was mainly male, and the sex ratio of male to female was 2.66: 1.00 (1 368 ∶ 514). In terms of age distribution, 30-69 years old was peak age. Farmer was the predominant occupational group. Conclusions:In 2010 to 2019, the incidence of brucellosis in Jinan City has increased and the epidemic areas have expanded year by year. Corresponding measures for brucellosis prevention and control should be developed according to epidemiological characteristics in order to strengthen the capacity of epidemic prevention and control measures.

ABSTRACT

Objective To evaluate the clinical characteristics and pregnant outcomes of gravidae with COVID-19. Methods This study involved nine gravidae with COVID-19 admitted to the Renmin Hospital of Wuhan University from January 22 to February 1, 2020. Their clinical data, including epidemiological history, clinical symptoms, laboratory examinations, chest CT, treatment, delivery mode, and pregnancy outcomes, were analyzed retrospectively. Specimens of maternal vaginal swab were collected in six pregnant women, and the specimens of amniotic fluid, cord blood, neonatal throat swab and breast milk samples were collected in four pregnant women who had a delivery during our study. All samples were tested for the existence of COVID-19. Descriptive analysis was applied in this study. Results (1) Among the nine cases, five were admitted in the third trimester and four in the second trimester. The median incubation period of COVID-19 was 8 (1-14) d. Fever was presented in all cases on admission, and the other commonly seen symptoms were cough (seven cases) and diarrhea (five cases). Other signs and symptoms were also reported, including shortness of breath, myalgia and fatigue (four cases in each), nasal obstruction, pharyngalgia, chest pain, and headache/dizziness (three cases in each), rash (two cases), and chills and expectoration (one case in each). The most common laboratory abnormalities were a decreased number of lymphocytes (seven cases) and elevated C-reactive protein (six cases). Chest CT scans were performed in seven women, and all showed patchy areas or ground-glass opacity in both lungs. Oligohydramnios was detected in only one case at 37 +5 weeks, which was 7 d after the diagnosis of COVID-19. (2) All nine cases received empiric antibiotic and antiviral therapy with Chinese medicine as adjuvant treatment. Eight patients required oxygen inhalation, and eight were treated with glucocorticoid. Six cases received immunotherapy. (3) Four of the nine cases had delivered, including three cesarean sections and one spontaneous vaginal preterm birth after premature rupture of membranes, and the mother was transferred to the intensive care unit 2 d after delivery due to acute respiratory distress syndrome. One case was terminated at 26 gestational weeks. Of the four neonates, there were two term and two premature babies, and one preterm baby was small-for-gestational-age. No neonatal asphyxia was observed. Serial real-time quantitative reverse transcription-polymerase chain reaction showed negative results in the detection of 2019-novel coronavirus in all samples obtained from amniotic fluid, umbilical cord blood, neonatal nasopharynx, breast milk, and vagina. Maternal conditions were all stable in all cases, including the four continuing pregnancy, and the terminated ones, except the case mentioned above. Conclusions There is no distinguishable clinical feature between pregnant and non-pregnant COVID-19 patients. So far, there is no evidence for vertical transmission or worsening perinatal outcome in mothers and babies.

ABSTRACT

OBJECTIVES@#To evaluate residents' knowledge, attitude and behavior towards coronavirus disease 2019 (COVID-19) in Hunan Province, and to explore the factors influencing behaviors.@*METHODS@#A self-designed questionnaire was used to conduct an online survey for 4 139 Hunan residents. The contents included general population information, residents' knowledge, attitude and practice to COVID-19.@*RESULTS@#Mean scores of knowledge, attitude, and behavior were 29.82±3.16, 6.71±1.12, and 14.93±1.45, respectively. Residents had the highest score of major symptoms of COVID-19 (3.96±0.39), but the lowest was the main transmission routes (3.47±0.89). A total of 22.68% of the residents were very or relatively afraid of the outbreak, but 95.22% of the residents had confidence in defeating COVID-19. In behavior dimension, "handling of suspicious symptoms" had the lowest score (3.58±0.75). The behavior implementation rate of "keep the surfaces of household items clean" (80.50%), "doing more exercise, reasonable diet, working and resting regularly" (84.59%), and "avoid hand contacting with eyes, mouth or nose" (89.51%) were relatively low. Pearson correlation coefficient showed that the knowledge, attitude, and practices score were correlated with each other (knowledge vs behavior: =0.366; knowledge vs attitude: =0.041; attitude vs behavior: =0.100; all <0.05). Multiple linear regression analysis showed that the knowledge, attitude and behavior on COVID-19 were mostly influenced by education background (all <0.05), and the independent factors affecting behavior included knowledge and attitude, gender, permanent residence, education background (all <0.05).@*CONCLUSIONS@#Residents in Hunan Province have a good knowledge, attitude, and behavior to COVID-19. Nevertheless there are still weak links to be improved in all dimensions. It is necessary to strengthen knowledge and behavior of family protection, and care for residents' psychological health, especially persons with low education degree, male and rural residents.

ABSTRACT

Objective:To evaluate the clinical characteristics and pregnant outcomes of gravidae with COVID-19.Methods:This study involved nine gravidae with COVID-19 admitted to the Renmin Hospital of Wuhan University from January 22 to February 1, 2020. Their clinical data, including epidemiological history, clinical symptoms, laboratory examinations, chest CT, treatment, delivery mode, and pregnancy outcomes, were analyzed retrospectively. Specimens of maternal vaginal swab were collected in six pregnant women, and the specimens of amniotic fluid, cord blood, neonatal throat swab and breast milk samples were collected in four pregnant women who had a delivery during our study. All samples were tested for the existence of COVID-19. Descriptive analysis was applied in this study.Results:(1) Among the nine cases, five were admitted in the third trimester and four in the second trimester. The median incubation period of COVID-19 was 8 (1-14) d. Fever was presented in all cases on admission, and the other commonly seen symptoms were cough (seven cases) and diarrhea (five cases). Other signs and symptoms were also reported, including shortness of breath, myalgia and fatigue (four cases in each), nasal obstruction, pharyngalgia, chest pain, and headache/dizziness (three cases in each), rash (two cases), and chills and expectoration (one case in each). The most common laboratory abnormalities were a decreased number of lymphocytes (seven cases) and elevated C-reactive protein (six cases). Chest CT scans were performed in seven women, and all showed patchy areas or ground-glass opacity in both lungs. Oligohydramnios was detected in only one case at 37 +5 weeks, which was seven days after the diagnosis of COVID-19. (2) All nine cases received empiric antibiotic and antiviral therapy with Chinese medicine as adjuvant treatment. Eight patients required oxygen inhalation, and eight were treated with glucocorticoid. Six cases received immunotherapy. (3) Four of the nine cases had delivered, including three cesarean sections and one spontaneous vaginal preterm birth after premature rupture of membranes, and the mother was transferred to the intensive care unit two days after delivery due to acute respiratory distress syndrome. One case was terminated at 26 gestational weeks. Of the four neonates, there were two term and two premature babies, and one preterm baby was small-for-gestational-age. No neonatal asphyxia was observed. Serial real-time quantitative reverse transcription-polymerase chain reaction showed negative results in the detection of 2019-novel coronavirus in all samples obtained from amniotic fluid, umbilical cord blood, neonatal nasopharynx, breast milk, and vagina. Maternal conditions were all stable in all cases, including the four continuing pregnancy, and the terminated ones, except the case mentioned above. Conclusions:There is no distinguishable clinical feature between pregnant and non-pregnant COVID-19 patients. So far, there is no evidence for vertical transmission or worsening perinatal outcomes in mothers and babies.

ABSTRACT

Objective:To explore the significance of empathy and executive function indexes in the diagnosis and classification of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD).Methods:According to DSM-Ⅴ diagnostic criteria, 33 children with ASD, 30 children with ADHD and 39 typical development (TD) children and adolescents were enrolled as the research subjects.The empathy and executive function characteristics were compared and analyzed in the subjects.Based on empathy and executive function indicators, the three groups of subjects were diagnosed and classified by machine learning method.Results:The total score of Griffith empathy measure parent ratings(GEM-PR)(ASD: (0.67±0.64), ADHD: (1.00±0.79), TD: (0.98±0.73)) and each factor score ( F=3.595-10.363, all P<0.05) and the total score of behavior rating inventory of executive function(BRIEF)(ASD: (62.79±7.45), ADHD: (59.47±8.77), TD: (49.08±7.91)) and each factor score of the three groups were different ( F=6.557-33.205, all P<0.01). Among them, the scores of empathy and executive function in ASD and ADHD groups were generally higher than those in TD children (all P<0.05). When combined with BRIEF scale and GEM scale, the classification accuracy of the three groups reached 62.75%. Conclusion:Both ASD and ADHD children have damages in empathy and executive function.Combining empathy and executive function indexes are more helpful for diagnosis and classification than single index.
