Objective To evaluate the validity, reliability and feasibility of Chinese version of Aggressive Behavior-Teacher' s Checklist (TCL) among preschool children. Methods TCL was translated and administered with Child Behavior Checklist (CBCI)-aggressive subscale to 148 preschool children in Shanghai. Validity and reliability of TCL was evaluated using standard psychometric analyses. Results Each item of Chinese version of TCL was significantly correlated with the subscale it belonged to(P<0. 01). The criterion validities of reactive aggressive subscale and proactive aggressive subscale among boys and girls were from 0.491 to 0. 733. The construct validity was also confirmed by factor analysis with 78.489% variance explained by two factors. Cronbach's alpha of TCL and its two subscales were 0. 891,0. 814, and 0. 880 respectively. The test-retest reliability and the inter-rater reliability coefficients of reactive aggressive subscale and proactive aggressive subscale were all above 0. 7. Conclusion Chinese version of Aggressive Behavior-Teachers Checklist has good validity and reliability among preschool children in Shanghai, and can be applied in kindergartens and schools to evaluate and deal with aggressive behavior among these children.

Objective:To identify the pathogenic gene mutations in a family with early onset severe retinal dystrophy (EOSRD).Methods:A retrospective clinical study. One patient and three family members from a Han of EOSRD who were diagnosed at Henan Eye Hospital in August 2018 were included in the study. After the detailed history of the patients was collected, all participants underwent best corrected visual acuity (BCVA), slit-lamp, fundus biomicroscopy with the slit lamp, untra-widefield fundus color photography, spectral-domain optical coherence tomography (SD-OCT) and full-field electroretinography (ff-ERG). The subject’s peripheral venous blood of 5 ml was collected and the whole genome DNA was extracted. A genetic eye disease capture chip containing 441 disease-causing genes was used for targeted capture and enrichment of high-throughput sequencing, and Sanger sequencing was performed for the clear pathogenic mutation sites; the analysis software was used for bioinformatics analysis of the mutation sites.Results:A 6-year-old female proband developed poor night vision in both eyes after 1 year old. The BCVA of both eyes were 0.1. The color of the optic disc was slightly lighter; the diameter of the retinal vessels was slightly reduced, and extensive pigment changes can be seen in the retina outside the vascular arch. SD-OCT examination showed that the outer membrane, ellipsoid zone and chimera zone in the central fovea of both eyes were unclear and intermittent. The visual area outside the fovea was neuroepithelial outer plexiform layer, outer nuclear layer, outer membrane, ellipsoid zone. The chimera zone gradually disappeared, and the thickness of the pigment epithelial layer was not uniform. In ff-ERG examination, the functions of the binocular cone and rod system were severely decreased. The results of genetic testing showed that there were c.921C>A homozygous mutations in the Tubby-like protein (TULP1) gene of the proband, and c.3121C>T and c.3488G>A compound heterozygous mutations in the cyclic nucleotide gated channel beta 1 (CNGB1) gene. Amino acid conservation analysis results showed that the above three mutation sites were highly conserved in multiple species; bioinformatics analysis results showed that TULP1 gene c.921C>A (p.Cys307*) had translation termination in the protein conserved region, CNGB1 gene c.3121C>T (p.Arg1041Trp) and c.3488G>A (p.Gly1163Glu) had amino acid polarity changes in the protein conserved region, which led to major changes in the protein spatial structure.Conclusion:TULP1 gene c.921C>A homozygous mutation, CNGB1 gene c.3121C>T and c.3488G>A compound heterozygous mutation are the mutation sites of this EOSRD family.

The need to maintain self-subject: the desire to maintain self-efficacy and self-image of dignity in life; the need to relieve the symptoms of self-discomfort. The need to relieve the physical symptoms and psychological discomfort. Meet the needs of self-determination: participate in medical care decisions and choose comfortable social relationships. Express their own emotional needs: the past farewell and remembrance and future wish to achieve the expectationsConclusions:Patients with end-stage cancer have diverse needs for hospice care. In clinical work, medical staff should adhere to the people-oriented concept, explore patients' needs and preferences, and implement individualized quality nursing measures to meet patients' needs for hospice care.

Objective To investigate the clinical diagnostic value of circulating tumor cells (CTCs)and circulating cell-free DNA (cfDNA) in peripheral blood samples in breast cancer. Methods From July 2017 to April 2018, 47 patients with BMC (7 in stage Ⅱ, 19 in stage Ⅲ and 21 in stage Ⅳ), 24 patients with benign breast diseases and 28 healthy people were selected. After collecting peripheral blood samples, serum and blood cells were separated. The size-based high-throughput microfluidic chip was used to capture CTCs. The real-time fluorescent quantitative PCR based on Alu sequence was used to detect the length of cfDNA(247 bp, 115 bp)in the serum, and the ratio of amplified products of long and short fragments was used as the index of DNA integrity. The Mann-Whitney U test or Kruskal-Wallis H test was used to compare the differences between the groups and analyze the relationship between CTCs and cfDNA and clinical parameters of breast cancer. The ROC curve was drawn and the area under the curve (AUC) was used to evaluate the feasibility of blood cell CTCs and plasma cfDNA detection as diagnostic criteria. Results The CTCs and cfDNA of 47 BMC patients were analyzed. The CTCs and cfDNA integrity index (Alu 247/115) of BMC patients were significantly higher than those of physical examination patients[(13.98± 12.36)cells / ml vs (1.14 ± 1.35) cells / ml; 0.7687 ± 0.3868 vs 0.5094 ± 0.2456], and the difference was statistically significant(the U value was 126.5,359.0;P<0.001), the area under ROC curve of CTCs was 0.885 (95％CI: 0.805-0.965), cut-off value was 7.68/ml, sensitivity was 80.4％, specificity was 96.4％. The area under ROC curve of Alu 247/115 was 0.727(95％CI: 0.608-0.847), cut-off value was 0.431, sensitivity was 71.7％, specificity was 71.4％. The AUC of CTCs and Alu 247/115 was 0.919 (95％CI 0.854-0.984), which was higher than the single test of each indicator. Conclusions CTCs and cfDNA may be the potential biological indicators for breast cancer diagnosis. The combined detection of CTCs and cfDNA maybe improve the diagnosis rate of breast cancer patients.

Objective:To investigate the risk factors for preoperative hypoxemia in geriatric patients with hip fracture.Methods:A case-control study was used to analyze the clinical data of 99 geriatric patients with hip fracture admitted to Zhongda Hospital affiliated to Southeast University between November 2020 and August 2021. There were 29 males and 70 females, aged 67-96 years [(82.6±6.2)years]. The patients were divided into hypoxemia group ( n=51) and non-hypoxemia group ( n=48) using partial arterial partial pressure of oxygen (PaO 2)<80 mmHg while breathing room air at emergency as the reference standard. The two groups were compared in terms of sex, age, fracture types, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, pulmonary diseases diagnosed by preoperative chest CT [atelectasis, pleural effusion, chronic obstructive pulmonary disease (COPD)], time from injury to visit, New York Heart Association (NYHA) classification, Barthel index, KATZ index, modified Medicine Research Council (mMRC) dyspnea scale, numeric rating scale (NRS), smoking, drinking, comorbidities (hypertension, diabetes mellitus, Parkinson′s disease, Alzheimer′s disease, cerebral infarction, coronary atherosclerotic heart disease), body temperature, blood routine test at first examination (erythrocyte count, leukocyte count, C-reactive protein, hemoglobin), biochemistry (serum albumin, blood glucose, blood creatinine, blood urea nitrogen), electrolyte (serum potassium, serum sodium), and other related examinations [D-dimer, brain natriuretic peptide (BNP), lactic acid]. Univariate analysis was performed to the correlation of those indicators with preoperative hypoxemia. Multivariate Logistic regression analysis was used to identify the independent risk factors for preoperative hypoxemia in geriatric patients with hip fracture. Results:Differences in sex, age, fracture types, BMI, pulmonary diseases diagnosed by preoperative chest CT, time from injury to visit, Barthel index, KATZ index, NRS, smoking, drinking, comorbidities, body temperature, first laboratory results of erythrocyte count, biochemistry, electrolyte and other related examinations were not statistically significant between the two groups (all P>0.05). The two groups showed statistical differences in ASA classification, NYHA classification, mMRC dyspnea scale, leukocyte count at first examination, C-reaction protein and hemoglobin (all P<0.05). Univariate analysis indicated that ASA classification, NYHA classification, mMRC dyspnea scale, leukocyte count at first examination and C-reaction protein were correlated with the occurrence of preoperative hypoxemia in geriatric patients with hip fracture (all P<0.05). Multivariate Logistic regressions analysis indicated that higher mMRC dyspnea scale ( OR=2.30, 95% CI 1.10-4.81, P<0.05), higher leukocyte count at first examination ( OR=1.24, 95% CI 1.05-1.45, P<0.05), higher level of C-reaction protein ( OR=1.02, 95% CI 1.01-1.03, P<0.05) and higher level of hemoglobin ( OR=1.04, 95% CI 1.01-1.07, P<0.05) were significantly correlated with the occurrence of preoperative hypoxemia in geriatric patients with hip fracture. Conclusion:Higher mMRC dyspnea scale, higher leukocyte count, higher level of C-reaction protein and higher level of hemoglobin are independent risk factors for preoperative hypoxemia in geriatric patients with hip fracture.

Objective:To determine the pathogenic gene mutation in a family with incomplete congenital quiescent night blindness (CSNB) of Schubert-Bornschein type.Methods:A retrospective clinical study. In February 2021, one patient and his parents and elder brother from a Han Chinese incomplete CSNB of Schubert-Bornschein type family diagnosed by clinical and genetic examination at Henan Provincial People's Hospital were included in the study. The patient’s medical history, family history were inquired; best corrected visual acuity (BCVA), color vision, fundus color photography, full-field electroretinogram (ERG), and frequency domain optical coherence tomography (OCT) were examined in detail. Five ml of the subject’s peripheral venous blood was collected and the whole genome DNA was extracted. The genomic DNA of the subject was library constructed, and all-exon probes were polymerized for capture. The suspected pathogenic mutation site was verified by Sanger, and the pathogenicity of the gene mutation site was determined by parallel bioinformatics analysis.Results:The BCVA of both eyes of the proband (Ⅱ2) was 0.4; the color vision test could not recognize the red color. Fundus examination showed no obvious abnormalities. The retina thickness in the macular area of both eyes was slightly thinned. ERG examination of the whole field showed that the amplitude of ERG b wave was significantly reduced under the stimulation of binocular dark adaptation 3.0 and showed a negative waveform. The mother of the proband (Ⅰ2) had normal BCVA, color vision, fundus color photography, and frequency domain OCT examination. The full-field ERG examination showed that the amplitude of each eye reaction was slightly reduced, and the amplitude of the dark adaptation shock potential was significantly reduced. Genetic testing showed that the proband (Ⅱ2) had a c.1761dupC hemizygous mutation in exon 14 of the voltage-dependent calcium channel α1F subunit gene ( CACNA1F gene). The results of protein sequence homology analysis showed that the site was highly conserved in multiple species; the results of bioinformatics analysis showed that the CACNA1F gene c.1761dupC (pY588fs) subsequently had a frameshift mutation and became a stop at position 10. Codons appear translational termination in the conserved regions of the protein. According to the standards and guidelines of the American College of Medical Genetics and Genomics, the mutation was judged to be a possible pathogenic variant. The mother of the proband (Ⅰ2) was a carrier of this site mutation. The clinical and genetic test results of the father and elder brother of the proband were not abnormal. Conclusion:CACNA1F gene c.1761dupC is the pathogenic mutation site of the Schubert-Bornschein type incomplete CSNB family.
