Objective To understand the situation of college students' knowledge, attitude and practice (KAP) of innovation and entrepreneurship activities and analyze their influencing factors, in order to provide a scientific basis for further promotion of innovation and entrepreneurship activities. Methods A self-administered questionnaire survey using cluster sampling method was conducted among 850 undergraduates in a medical university in May, 2018. The demographic characteristics and questions pertaining to the KAP of innovation and entrepreneurship activities were collected, The weighted scores of KAP were calculated using the Delphi method. Chi-square test, multivariate logistic regression and linear regression analysis were used to analyze the data. Results A total of 850 questionnaires were sent out and 800 valid questionnaires were collected. The average scores and pass rates for the knowledge, attitude and practice of the 800 college students were (0.54 ±0.14), 38.1％; (0.56 ±0.23), 51.5％; and (0.37 ±0.19), 12.6％, respectively. Knowledge: the pass rate for the concepts related to innovation and entrepreneurship was 70.5％, and the pass rate for the policies related to innovation and entrepreneurship was 17.2％. The pass rate of senior students and excellent students were higher than those of junior students and students of lower academic competence (P=0.000, P=0.004). Attitudes: the pass rate for attitude towards the relationship between innovation and entrepreneurship and personal development was 63.6％, the pass rate for attitudes towards participation in innovation and entrepreneurship was 49.8％, and the pass rate for attitudes towards the school continuing to carry out innovation and entrepreneurship related activities was 23.8％. Practice:the pass rates for participation in scientific research and academic activities and social practice , voluntary cultivation of innovation ability and self-employment were 8.5％, 62.9％, 11.9％and 27.3％, respectively. The pass rate of senior grades was higher than that of junior grades (P=0.001). Scores for knowledge and those of attitude are positively correlated. Scores for practice and those of knowledge and attitude are positively correlated. Conclusion The higher pass rates for medical college students' attitude toward innovation and entrepreneurship activities as compared to those for knowledge and practice indicates high eagerness toward participation in innovation and entrepreneurship activities; a high rate knowledge is conducive to the cultivation of attitudes and the improvement of participation in activities . Therefore , it is necessary to strengthen the efforts in carrying out innovation and entrepreneurship activities , improve publicity and education, and promote the awareness-raising of innovation and entrepreneurship.

Objective: To analyze the influencing factors of acute gastroenteritis outbreaks caused by norovirus in Beijing from 2014 to 2018. Methods: Data of acute gastroenteritis events caused by norovirus in Beijing from April 2014 to March 2018 were collected. Unconditional logistic regression model was conducted to identify the risk factors of the outbreaks. Results: A total of 765 acute gastroenteritis epidemics caused by norovirus were reported in Beijing, in which 85.88% (657/765) were cluster events and 14.12% (108/765) were outbreaks. Among the outbreaks, 70.37% (76/108) were reported in 2017; 84.26% (91/108) were reported in winter and spring; 88.89% (96/108) were reported in kindergartens, primary or secondary schools; 81.48% (88/108) were through person-to-person transmission; 93.52% (101/108) were caused by norovirus GⅡ infection. The risk of outbreaks in suburban and out suburb area were 1.84 times (95%CI: 1.13-3.02) and 3.78 times (95%CI: 1.62-8.82) as high as that in urban area, respectively. The risks of outbreaks in primary, secondary schools and other institutions were 6.26 times (95%CI: 3.53-11.10), 14.98 times (95%CI: 6.23-36.01) and 8.71 times (95%CI: 3.07-24.71) as high as that in kindergartens, respectively. The risk of outbreak in which patients having lower hospital visiting rate than the median rate of all events was 2.29 times than that in the context of having higher hospital visiting rate (95%CI:1.42-3.68). The risk of foodborne outbreak was 14.55 times as high as that transmitted through person-to-person (95%CI: 3.15-67.07). Conclusion Measures such as strengthening the prevention and control of norovirus outbreaks in suburbs, primary schools, secondary schools and other institutions, promoting patients to visit the hospital actively, improving the management of foodborne events and kitchen workers should be taken to reduce the incidence of acute gastroenteritis outbreaks caused by norovirus.

Objective To investigate six-minute walk distancc (6MWD) of inpatients underwent cardiac surgery before discharge and to identify its influencing factors,and to provide references for further studies of hospital rehabilitation.Methods Using convenience sampling,from August 2016 to June 2017,167 eligible patients underwent cardiac surgery were recruited from a cardiovascular hospital in Beijing.General and disease-related intormation were collected.According to requirements of six-minute walk tcst (6MWT) from American Thoracic Society,patients' rehabilitation was evaluated using 6MWD.Results After discharge from intensive care unit(ICU),6MWD of patients increased along with hospital stays.On the day before discharge,mean 6MWD of patients was (213.86±75.87).The influencing factors of 6MWD included types of surgery (P=0.019),cardiopulmonary bypass (P=0.004),postoperative left ventdcular ejection fraction (LVEF)(P=0.015),and hospital stays after discharge from ICU (P=0.003).Conclusion During hospitalization,6MWD of patients underwent cardiac surgery increased along with hospital stays.On the day before discharge,6MWD of patients tended to be stable,and ready for further rehabilitation process.Patients could have different rehabilitation differences in types of surgery,using cardiopulmonary bypass,LVEF and hospital stays after discharge from ICU.

OBJECTIVE: To explore the clinical features and genetic etiology of two children with intellectual developmental disorder and microcephaly with pontine and cerebellar hypoplasia (MICPCH). METHODS: Two children with MICPCH who were presented at the Henan Provincial People's Hospital between April 2019 and December 2021 were selected as the study subjects. Clinical data of the two children were collected, along with peripheral venous blood samples of them and their parents, and amniotic fluid sample of the mother of child 1. Whole exome sequencing (WES), array-comparative genomic hybridization (aCGH) and real-time quantitative PCR (qPCR) were carried out for the children, their parents and the fetus. The pathogenicity of candidate variants were evaluated. RESULTS: Child 1 was a 6-year-old girl featuring motor and language delay, whilst child 2 was a 4.5-year-old girl mainly featuring microcephaly and mental retardation. WES revealed that child 2 has harbored a 158.7 kb duplication in Xp11.4 (chrX: 41446160_41604854), which has encompassed exons 4~14 of the CASK gene. The same duplication was not found in either of her parents. aCGH revealed that child 1 has harbored a 29 kb deletion at Xp11.4 (chrX: 41637892_41666665), which encompassed exon 3 of the CASK gene. The same deletion was not found in either of her parents and the fetus. The above results were confirmed by qPCR assay. Above deletion and duplication were not found in the ExAC, 1000 Genomes and gnomAD databases. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were rated as likely pathogenic (PS2+PM2_Supporting). CONCLUSION The deletion of exon 3 and duplication of exons 4~14 of the CASK gene probably underlay the pathogenesis of MICPCH in these two children, respectively.

OBJECTIVE: To explore the genetic basis for fetus with bilateral lateral ventriculomegaly. METHODS: Fetus umbilical cord blood and peripheral blood samples of its parents were collected. The fetus was subjected to chromosomal karyotyping, whilst the fetus and its parents were subjected to array comparative genomic hybridization (aCGH). The candidate copy number variation (CNV) were verified by qPCR, Application goldeneye DNA identification system was used to confirm the parental relationship. RESULTS: The fetus was found to have a normal karyotype. aCGH analysis indicated that it has carried a 1.16 Mb deletion at 17p13.3, which partially overlapped with the critical region of Miller-Dieker syndrome (MDS), in addition with a 1.33 Mb deletion at 17p12 region, which is associated with hereditary stress-susceptible peripheral neuropathy (HNPP). Its mother was also found to harbor the 1.33 Mb deletion at 17p12. qPCR analysis confirmed that the expression levels of genes from the 17p13.3 and 17p12 regions were about the half of that in the normal control, as well as the maternal peripheral blood sample. Parental relationship was confirmed between the fetus and its parents. Following genetic counseling, the parents has chosen to continue with the pregnancy. CONCLUSION The fetus was diagnosed with Miller-Dieker syndrome due to the de novo deletion at 17p13.3. Ventriculomegaly may be an important indicator for prenatal ultrasonography in fetuses with MDS.

OBJECTIVE: To explore the genetic etiology of two patients with developmental delay and intellectual disability. METHODS: Two children who were respectively admitted to Henan Provincial People's Hospital on August 29, 2021 and August 5, 2019 were selected as the study subjects. Clinical data were collected, and array comparative genomic hybridization (aCGH) was carried out on the children and their parents for the detection of chromosomal microduplication/microdeletions. RESULTS: Patient 1 was a 2-year-and-10-month female and patient 2 was a 3-year-old female. Both children had featured developmental delay, intellectual disability, and abnormal findings on cranial MRI. aCGH revealed that patient 1 has harbored arr[hg19] 6q14.2q15(84621837_90815662)×1, a 6.19 Mb deletion at 6q14.2q15, which encompassed ZNF292, the pathogenic gene for Autosomal dominant intellectual developmental disorder 64. Patient 2 has harbored arr[hg19] 22q13.31q13.33(46294326_51178264)×1, a 4.88 Mb deletion at 22q13.31q13.33 encompassing the SHANK3 gene, haploinsufficiency of which can lead to Phelan-McDermid syndrome. Both deletions were classified as pathogenic CNVs based on the guidelines of American College of Medical Genetics and Genomics (ACMG) and were not found in their parents. CONCLUSION The 6q14.2q15 deletion and 22q13-31q13.33 deletion probably underlay the developmental delay and intellectual disability in the two children, respectively. Haploinsufficiency of the ZNF292 gene may account for the key clinical features of the 6q14.2q15 deletion.

Objective:To summarize the clinical characteristics of neonatal late-onset sepsis (LOS) caused by Leclercia adecarboxylata, and provide evidence for its diagnosis and treatment. Methods:We report a case of Leclercia adecarboxylata induced LOS in a male preterm neonate diagnosed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) at the Affiliated Suzhou Hospital of Nanjing Medical University. Relavant literature was retrieved from Wanfang, VIP, CNKI, and PubMed databases up to April 2021, using terms including "neonate" "sepsis" and " Leclercia adecarboxylata". Results:The patient presented with dyspnea immediately after birth with gestational age of 34 +3 weeks and birth weight of 2 050 g. After admission at 14 min after birth, he was incubated at temperature of 33-35 ℃ and humidity of 50%-60% and received active treatment, consisting of nasal continuous positive airway pressure, tracheal intubation, intratracheal injection of pulmonary surfactant, invasive mechanical ventilation, and anti-infective treatment with piperacillin, cefoperazone/sulbactam, and meropenem. However, the patient developed LOS on day 11 of life and eventually died of disseminated intravascular coagulation and multiple organs failure despite volume expansion, anti-infective therapy, and respiratory support. The blood culture was positive for Gram-negative rod and confirmed as a multi-drug resistant strain of Leclercia adecarboxylata. Two cases of LOS caused by sensitive strain of Leclercia adecarboxylata in premature female infants were retrieved in the literature with atypical symptoms, of whom one was successfully treated and one died after active treatment. Conclusions:Leclercia adecarboxylata infection alone can lead to LOS in preterm infants without typical manifestations. MALDI-TOF MS is helpful for the diagnosis and rational application of antibiotics.
