BACKGROUND: Previous research demonstrated that a homozygous mutation of g.136372044G>A (S12N) in caspase recruitment domain family member 9 ( CARD9 ) is critical for producing Aspergillus fumigatus -induced ( Af -induced) T helper 2 (T H 2)-mediated responses in allergic bronchopulmonary aspergillosis (ABPA). However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA. METHODS: A total of 61 ABPA patients and 264 controls (including 156 healthy controls and 108 asthma patients) were recruited for sequencing the CARD9 locus to clarify whether patients with this heterozygous single-nucleotide polymorphisms are predisposed to the development of ABPA. A series of in vivo and in vitro experiments, such as quantitative real-time polymerase chain reaction, flow cytometry, and RNA isolation and quantification, were used to illuminate the involved mechanism of the disease. RESULTS: The presence of the p.S12N mutation was associated with a significant risk of ABPA in ABPA patients when compared with healthy controls and asthma patients, regardless of Aspergillus sensitivity. Relative to healthy controls without relevant allergies, the mutation of p.S12N was associated with a significant risk of ABPA (OR: 2.69 and 4.17 for GA and AA genotypes, P = 0.003 and 0.029, respectively). Compared with patients with asthma, ABPA patients had a significantly higher heterozygous mutation (GA genotype), indicating that p.S12N might be a significant ABPA-susceptibility locus ( aspergillus sensitized asthma: OR: 3.02, P = 0.009; aspergillus unsensitized asthma: OR: 2.94, P = 0.005). The mutant allele was preferentially expressed in ABPA patients with heterozygous CARD9S12N , which contributes to its functional alterations to facilitate Af -induced T H 2-mediated ABPA development. In terms of mechanism, Card9 wild-type ( Card9WT ) expression levels decreased significantly due to Af -induced decay of its messenger RNA compared to the heterozygous Card9S12N . In addition, ABPA patients with heterozygous CARD9S12N had increased Af -induced interleukin-5 production. CONCLUSION Our study provides the genetic evidence showing that the heterozygous mutation of CARD9S12N , followed by allele expression imbalance of CARD9S12N , facilitates the development of ABPA.

Objective: To understand the status of family sex education and associated factors among preschoolers in Wuhu, providing scientific basis for child family sex education. Methods: From July to August 2020, random cluster sampling was used to select 481 children from 5 kindergartens in Wuhu. A questionnaire survey among parents of these preschoolers regarding family sex education status and its influencing factors. Results: A total of 285(59.25%) parents reported family sex education for children, and 196(40.75%) did not practice family sex education for their children. Multivariate Logistic regression analysis showed parental awareness of sex education content(OR=3.06, 95%CI=1.95-4.78), parental anxiety for child sexual assault (OR=1.82, 95%CI=1.11-2.99) were associated with higher rate of family sex education. Conclusion Family sex education among preschoolers in Wuhu should be further promoted. Sex education training towards parents might help improve children s family sex education.

Objective: To investigate the effect of online and offline mindfulness training on improving anxiety and depression and sleep quality of college students,and to provide a reference for mental health promotion among college students. Methods: From October 2020, a total of 1 203 university students from North China University of Technology were screened with the Self rating Anxiety Scale (SAS), Self rating Depression Scale (SDS) and Pittsburg Sleep Quality Index (PSQI) using the whole group radom cluster sampling method. Totally 103 students who met the inclusion criteria were randomly divided into 64 online and 39 offline groups. The degree of improvement in anxiety, depression and sleep quality was assessed after the intervention. Results: The SAS, SDS and PSQI scores of college students after the online and offline the mindfulness training intervention significantly decreased compared with score before the intervention( t =5.57, 5.31, 3.99; 4.88,5.02, 5.88, P <0.01). The difference in the degree of improvement in sleep quality between the two interventions, online and offline, was statistically significant ( t =-2.55， P <0.05). The less the three symptoms of anxiety, depression and sleep were combined in university students, the higher the symptom remission rate of the positive mindfulness training (25% remission rate for all three symptoms together, 40% remission rate for two symptoms together and 100% remission rate for only one symptom). Conclusion Both online and mindfulness training can be used as an effective intervention for sleep, anxiety and depression; offline mindfulness training is more effective than online in improving sleep quality in university students; mindfulness training is more effective in relieving single symptoms.

Objective:To investigate the effects of pre-existing antibody on seroconversion rate after influenza vaccination.Methods:This study recruited 1 900 healthy volunteers to receive influenza split vaccines in Xinjiang Uygur Autonomous region and Yunnan Province from September 2009 to October 2018. Hemagglutinin agglutination inhibition assay was used to detect the titers of specific antibodies in blood samples collected before vaccination and 28 d after vaccination and the effects of pre-existing antibody on the seroconversion to different influenza vaccine components were analyzed.Results:Trend analysis showed that with the increasing titer of pre-existing antibody, the seroconversion rates to A/H1N1, A/H3N2, B/Victoria and B/Yamagata vaccine components were gradually decreased (χ 2=121.76, P<0.001; χ 2=67.58, P<0.001; χ 2=45.25, P<0.001; χ 2=54.55, P<0.001). After adjusting for factors such as region, gender and age, multivariate logistic regression showed that pre-existing antibody titer equal to or higher than 40 was an independent factor that affected the seroconversion to A/H1N1, A/H3N2 and B/Victoria vaccine components, and the adjusted OR (95%CI) values were 2.50(2.00-3.13)、1.64(1.35-2.00) and 2.50(1.79-3.45), respectively. Conclusions:The seroconversion rate to each vaccine component was negatively correlated with the pre-existing antibody titer. The factor that pre-existing antibody titer equal to or higher than 40 was detrimental to the seroconversion to A/H1N1, A/H3N2 and B/Victoria vaccine components, but had no significant influence on B/Yamagata seroconversion.

Facial injuries due to animal bites are normal. Recent studies have demonstrated that primary wound closure with cosmetic suture techniques and/or plastic and reconstructive repair techniques for facial injuries caused by animal bites will improve the cosmetic effect and patients' satisfaction without increasing the wound infection rate. Hence, early plastic surgery is recommended to repair facial injuries caused by animal bites. The authors review the characteristics and injury assessment of facial injuries caused by animal bites, wound debridement techniques, cosmetic suture techniques, and cosmetic sutures of animal bites in various parts, aiming to provide a reference to the plastic and reconstructive therapy for facial injuries caused by animal bites.

BACKGROUND: Fatal aortic rupture caused by esophageal foreign body (EFB), is associated with a high mortality, but can be prevented by thoracic endovascular aorta repair (TEVAR) that performed increasingly as technology improves. This study aims to investigate the cause, management and prognosis of suspected penetrating aortoesophageal foreign body injury. METHODS: Twelve cases who met the criteria were enrolled in this study. The demographic and clinical data were reviewed for evaluating the characteristics of EFB. RESULTS: Among 12 cases enrolled, 7 were males and 5 were females, with an age 27–86 years. The distance of EFB from aorta (DFA) of 7 cases were less than or equal to 0 mm, 5 cases were 0–2 mm. Eleven cases were managed with TEVAR, only one case was with open surgery standby but fi nally treated by fl exible endoscopy (FE) successfully, without TEVAR. In group with TEVAR, EFB of 7 cases were successfully removed by rigid endoscopy (RE), and one of them was failed at the first RE treatment. EFB of 2 cases were successfully removed by open surgery with TEVAR, and other 9 cases were managed by endoscopies with TEVAR. The mean length of stay of hospitalization (LOS) and length of ICU stay of patients treated by open surgery with TEVAR (18.50±2.12 days and 5.50±0.71 days) was signifi cantly longer than those of patients treated by endoscopy with TEVAR (7.00±2.74 days and 1.33±1.12 days, P<0.001 and P=0.001, respectively). Five cases had severe complications. CONCLUSION: Rational application of TEVAR can be a life-saving management for aortoesophageal foreign body injury, and jointed with endoscopy is safe and effective with a shorter length of ICU or total hospital stay.
