Objective:To investigate the distribution characteristics and clinical significance of non-bacterial respiratory pathogens in children with respiratory tract infection.Methods:A total of 5 718 children with respiratory tract infection treated in outpatient, emergency and inpatient of Children′s Hospital Affiliated to Capital Institute of Pediatrics from January to December 2019 were retrospectively analyzed.Pharyngeal swabs were collected and nucleic acids of 7 common non-bacterial respiratory pathogens were detected and analyzed by double amplification technique. Chi square test was used to compare the rates. Results:A total of 5 718 children were included in the study.At least one respiratory pathogen nucleic acid positive was detected in 1 835 cases (32.09%). A total of 98 children had mixed infection of more than 2 pathogens (1.71%), which were mainly Mycoplasma pneumoniae (MP) and parainfluenza virus (PIV). The positive rates of 7 respiratory pathogens from high to low were MP (12.31%), PIV (6.23%), RSV (6.14%), influenza A virus (4.62%), adenovirus (2.80%), influenza B virus (1.40%) and chlamydia pneumoniae (0.33%). The positive rate of pathogens in male patients was 32.07% (1 073/3 346 cases), which was 32.12% (762/2 372 cases) in female patients.There was no significant difference in the positive rate of pathogens between males and females ( χ2=0.002, P=0.964). The positive rate of MP infection in male patients was significantly lower than that in females (11.48% vs. 13.49%) ( χ2=5.217, P=0.022). The total positive rate of infection in the 6 to <12 years old group was the highest (42.41%). The total positive rate (44.93%) and mixed infection rate (3.33%) were significantly higher in the fourth quarter than those of the others (30.43% vs.27.31% vs.34.59% vs.44.93%, 1.23% vs.1.10% vs.1.40% vs.3.33%; χ2=110.971, 26.968, all P<0.001). The total positive rate of pathogen infection in the outpatient and emergency department was 41.74% (606/1 452 cases), which was significantly higher than that of hospitalized children (31.13%) (1 328/4 266 cases) ( χ2=54.438, P<0.001). Conclusions:Non-bacterial respiratory pathogens are important pathogens leading to respiratory tract infections in children, among which MP infection is the most prevalent.Timely and accurate detection of pathogens is helpful for the diagnosis and treatment of respiratory tract infection and avoiding the abuse of antibiotics.

Objective:To explore the correlation between parents′ posttraumatic growth, mental resilience and family functioning in children with autism spectrum disorder.Methods:Using the convenience sampling method, 169 parents of children with autism spectrum disorders were selected. General data questionnaire, Posttraumatic Growth Inventory (PTGI), Conner-Davidson Resilience Scale (CD - RISC) and Family Assessment Device (FAD) were investigated.Results:The total PTGI score of parents of children with autism spectrum disorder was 58.79±18.92. The scores of appreciation of life, new possibilities, personal strength, relating to others and spiritual change were 19.49±6.15, 10.46±4.59, 9.05±3.32, 7.79±3.65, 12.01±3.83. The PTGI score of 37.3% parents was lower than 52, which was at a low level. Parents in the high score (> 74) group and the low score (< 52) group had statistically significant differences ( P<0.05) in the total score of CD - RISC and scores in all dimensions, as well as the differences in the scores of the four dimensions of FAD, namely problem solving, communication, role and behavior control. The total score of PTGI of parents was positively correlated with the total score of CD - RISC and the scores of its all dimensions ( r values were 0.201-0.317, P<0.05), and negatively correlated with the scores of Problem Solving, Communication and Behavioral Control of FAD ( r values were -0.233 - -0.196, P<0.05). Conclusions:The parents of children with autism spectrum disorder have an average level of posttraumatic growth. People with better mental resilience and healthier family functions have higher post-traumatic growth level.

Objective:To assess the utility of contrast-enhanced ultrasound (CEUS) targeted biopsy (TB) for clinically significant prostate cancer (PCa) detection.Methods:A total of 983 consecutive patients scheduled for prostate biopsy from October 2015 to March 2019 in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine were enrolled in this retrospective study. All patients had suspicious lesions on CEUS, defined as increased focal contrast enhancement, rapid contrast enhancement and low enhancement lesions with ill-defined borders. Suspicious lesions on CEUS were sampled in addition with standard 12-core systematic biopsy(SB). Clinically significant PCa was defined using Epstein criteria. The clinically significant PCa detection rate by CEUS-TB and combined biopsy was evaluated in comparison with SB.Results:In 502 of the 983 patients, the diagnosis of PCa was histologically confirmed, including 445 patients with clinically significant PCa and 57 patients with clinically insignificant PCa. The clinically significant PCa by CEUS-TB and combined biopsy were 41.9% (412/983) and 45.3% (445/983) respectively, which was significantly higher than SB (36.8%, 362/983)(all P<0.001). CEUS-TB resulted in additional 83 cases of clinically significant PCa, including 61 patients missed by SB and 22 patients under-graded by SB. Conclusions:CEUS is helpful in the detection of PCa lesions. Combined CEUS-TB and SB can improve the clinically significant PCa detection rate.
