ABSTRACT
Objective@#To explore the current status related to behavioral problems among children and adolescents aged 12-16 years old in Guizhou Province, China, and to provide a reference for timely prevention and intervention measures.@*Methods@#To capture different economic development levels, a multistage stratified cluster sampling method was used. A total of 3 217 children and adolescents aged 12-16 years old from six middle schools and six primary schools in Guiyang, Duyun, Kaili City from Guizhou Province participated in this study. The Achenbach Child Behavior Checklist (CBCL) and a self designed questionnaire were administered between August and December 2021.@*Results@#The overall detection rate of behavioral problems among the students was 16.60% , and the rate was 14.41% and 18.62% among male and female students, respectively. The results of the Logistic regression analysis showed that good peer relationships ( OR=0.25, 0.16, P <0.05) were associated with a lower risk of behavioral problems in children and adolescents. However, the following factors were associated with an elevated risk of behavioral problems: nonparents as the main caregivers( OR = 1.44 ); children s daily screen time was 1-2 h ( OR =1.47) or more than 2 h( OR =2.75); children who had no sports hobbies( OR = 1.36); father parenting for doting or neglect( OR =1.85, 2.01); maternal parenting for doting( OR = 2.12 ); father had bad life habits( OR =1.69); father and mother were occasionally sick( OR =1.30, 1.38)( P <0.05).@*Conclusion@#Behavioral problems among children and adolescents in Guizhou Province is related to children s unhealthy living habits and various factors in the family environment. It is suggested that families, schools and relevant functional departments give full play to their own advantages and take comprehensive measures to prevent the occurrence of behavioral problems among children and adolescents.
ABSTRACT
Objective:To describe the changes of post-traumatic growth and rumination in coronary heart disease patients at different time points after PCI, and to analyze the correlation between them in order to provide evidence for personalized intervention.Methods:A cross-sectional study was conducted, a total of 234 patients with coronary heart disease who underwent PCI for the first time in the Department of Cardiology, the First Affiliated Hospital of China Medical University from December 2021 to October 2022 were studied by convenience sampling. The general data questionnaire, the Chinese version of the Event-Related Rumination Inventory and the simplified Chinese version of the Posttraumatic Growth Inventory were used to survey before discharge (T 0), first month after surgery (T 1), and three months after surgery (T 2). Results:The total scores of post-traumatic growth at the time point of T 0, T 1 and T 2 were 53.08 ± 13.47, 54.77 ± 11.20 and 59.32 ± 7.95, the difference was statistically significant ( F = 78.45, P<0.01). The scores of instrusive rumination at the time point of T 0, T 1 and T 2 were 14.92 ± 6.07, 15.78 ± 4.64 and 12.31 ± 3.38, the difference was statistically significant ( F = 46.58, P<0.01). The scores of deliberate rumination were 14.63 ± 4.74, 15.52 ± 3.93 and 17.86 ± 3.70, the difference was statistically significant ( F = 76.20, P<0.01). Instrusive rumination at T 0, T 1 and deliberate rumination at each point were positively correlated with the total score of post-traumatic growth ( r values were 0.229 to 0.414, all P<0.01). Instrusive rumination at T 2 was negatively correlated with posttraumatic growth scores ( r = -0.351, P<0.01). The deliberate rumination at T 2 time point was positively correlated with the total score of post-traumatic growth ( r = 0.403, P<0.01). Conclusions:The level of posttraumatic growth in patients with coronary heart disease after PCI needs to be improved, and targeted intervention should be planned early to change patients′pessimistic cognition caused by the disease, promote the development of positive thinking, then promote their posttraumatic growth.
ABSTRACT
Objective:To observe and analyze the atypical magnetic resonance imaging (MRI) findings and misdiagnosis reasons of primary central nervous system lymphoma (PCNSL), and to explore the value of conventional MRI signs combined with minimum apparent diffusion coefficient value (ADCmin) and imaging features of magnetic resonance spectroscopy (MRS) in the diagnosis and differentiation of atypical PCNSL.Methods:The clinical and imaging data of 15 patients with atypical PCNSL confirmed by clinical and pathological findings from Lianyungang Second People′s Hospital and the Affiliated Hospital of Xuzhou Medical University from January 2015 to December 2020 was collected. All cases were examined by plain MRI, enhanced and diffusion weighted imaging (DWI), and 3 cases were examined by MRS. The conventional MRI features, DWI signal features and MRS imaging features of 15 cases of atypical PCNSL were observed and analyzed, and the MRI findings of atypical PCNSL and the causes of misdiagnosis were summarized and analyzed. The ADCmin of tumor parenchyma, the mean ADC values of proximal peritumor, distal peritumor and contralateral white matter were detected and compared to explore the variation rules of ADC values in different regions.Results:Of the 15 cases of PCNSL, 14 cases were single and 1 case was multiple, with a total of 21 lesions. (1) Single lesions in rare sites: 4 cases in the superficial part of the brain, 1 case in the bridge arm, 1 case in the cerebellar hemisphere, 1 case in the suprasellar saddle, and 1 case in the third ventricle. (2) Atypical MRI findings: cystic degeneration or necrosis in 5 lesions (5/21), accompanied by hemorrhage in 1 lesion (1/21); There were 3 isosensitive lesions on DWI, and isosensitive lesions on ADC false color images. There were 5 ring enhancement lesions and 3 sheet enhancement lesions. (3) Multi-center growth pattern: 1 case with a total of 7 lesions, located in the right thalamus, basal ganglia and corona radiata, showing multiple nodules and ring enhancement. 1H-MRS examination showed that choline (Cho) peak increased, creatine (Cr) peak decreased, N-acetyl aspartate (NAA) peak decreased, and obvious Lip peak appeared in all the 3 cases with single lesions. 2 cases showed high Lip peak as the first peak. The ADCmin values of tumor parenchyma, proximal peritumor, distal peritumor and contralateral white matter showed a parabola pattern of first rise and then decline, as follows: (0.54±0.06)×10 -3 mm 2/s, (1.55±0.10)×10 -3 mm 2/s, (1.45±0.09)×10 -3 mm 2/s, (0.85±0.03)×10 -3 mm 2/s, overall difference was statistically significant ( F=630.570, P<0.001). The pairwise comparison was statistically significant (all P<0.05). Conclusions:Atypical PCNSL is easy to be misdiagnosed. Conventional MRI feature analysis combined with DWI and MRS imaging features and comparison of ADC values in different tumor areas are helpful for the diagnosis and differentiation of PCNSL and are expected to improve diagnostic accuracy.
ABSTRACT
Objective To explore the value of MRI in differential diagnosis of primary central nervous system lymphoma (PCNSL) and high grade glioma (HGG) in deep brain.Methods Features of routine MRI and DWI of 28 PCNSL (PCNSL group) and 30 HGG patients (HGG group) with single lesion in deep brain confirmed clinically and pathologically were analyzed,then apparent diffusion coefficient (ADC) and relative ADC (rADC) were measured.The optimal diagnostic threshold (OT) and diagnostic performance of ADC and rADC values were calculated according to the ROC curve.Results The incidence of capsule,necrosis,hemorrhage,enhancement heterogeneity and DWI signal strength were significantly different between the two groups (all P<0.05).ADC values were statistically different between lesions and the control side of the brain white matter in PCNSL and HGG patients (both P<0.001).ADC values and rADC values of PCNSL lesions were significantly lower than those of HGG lesions (all P<0.001).Taking ADC=0.86 × 10-3 mm2/s as a threshold,the sensitivity,specificity and accuracy in differential diagnosis of PCNSL and HGG was 92.9%,80.0% and 86.2%,respectively,and the area under curve was 0.946 (P< 0.001).Taking rADC =1.02 as a threshold,the sensitivity,specificity and accuracy in differential diagnosis of PCNSL and HGG was 92.9%,86.7% and 89.7%,respectively,and the area under curve was 0.957 (P<0.001).Conclusion MRI differential diagnosis can provide reliable information for clinical treatment of PCNSL and HGG in deep brain.
ABSTRACT

ABSTRACT
In previous study we isolated a gram-positive bacterial strain, designated Niu-O16, from bovine rumen gastric juice. The growing cells of bacterial strain Niu-O16 is capable of biotransforming isoflavone daidzein into dihydrodaidzein efficiently under anaerobic conditions. In this study we investigated the optimal bioconversion conditions for the resting cells of bacterial strain Niu-O16 to convert daidzein into dihydrodaidzein. Single factor test showed that the optimal conditions for the initial pH of phosphate buffer, the concentration of the resting cell and the concentration of the substrate daidzein were 6.0-8.0, 32-64 mg/mL (wet weight) and 0.8-1.2 mmol/L, respectively. Orthogonal experiments were used to determine the optimal combination of the resting cell concentration, substrate concentration and biotransformation time. The results showed that the optimal combination included resting cell concentration 32 mg/mL, substrate concentration 0.8 mmol/L and the biotransformation time 24 h. Furthermore, the biotransformation kinetics under optimal conditions were studied, under which conditions the highest bioconversion rate was 63.9% in the resting cell system. The results might provide information for resting cell biotransforming of anaerobes as well as its industrial application.
