Objective To investigate the iron regulated locus in Klebsiella pneumoniae isolates from blood culture of liver abscess patients in Sichuan Provincial People’s Hospital. Methods From January to December of 2015, a total of 10 isolates of Klebsiella pneumoniae were collected from blood culture of liver abscess patients from Sichuan Provincial People’s Hospital. The genomic DNA was extracted to identify the genes of iroB, iroC, and iroD by PCR, and data was further analyzed by Graphpad Prism 5 software. Results Among the 10 Klebsiella pneumoniae clinical strains, 9 strains were iroB positive strains, 9 strains were iroC positive strains, and 10 strains were iroD positive strains, 9 strains were iroB/C/D triple positive. Conclusion The current study suggests that the frequency of triple positive of iroB/C/D in Klebsiella pneumoniae is high in isolates from liver abscess patients, the triple positive of iroB/C/D may contribute to liver abscess.
Objective To investigate the expressions of β1, 3-N-acetyl glucosaminyl transfrases ( Fringe) ( RFNG, LFNG and MFNG) in lung tissues and lung T cells isolated from asthmatic mice, and to explore the role of Fringe in pathogenesis of asthma. Methods Asthmatic BALB/ c mouse model was established by inhalation of ovalbumin after intraperitoneal injection. Meanwhile, the control groups were established by normal saline. Lung tissues were sampled after 24 hours since the last stimulation. T cells were isolated from the lung tissues using percol and NylonFiber. The mRNA expressions of three kinds of Fringe in the lung tissues and lung T cells were examined by reverse transcription-PCR ( RT-PCR) . The protein expressions of Fringe in the lung tissues were detected by Western blot. Results The mRNA expressions of RFNG, LFNG and MFNG were detectable in the lung tissues and lung T cells. The mRNA expressions of RFNG increased in the asthmatic group compared with the control group( lung tissues: 0. 92 ±0. 35 vs 0. 51 ±0. 13, P lt; 0. 01; lung T cells: 0. 33 ±0. 06 vs 0. 18 ±0. 07, P lt; 0. 01) . LFNG mRNA had lower expression level in the asthmatic group( lung tissue: 0. 77 ±0. 32 vs 1. 61 ±0. 31, P lt; 0. 01; lung T cells: 0. 49 ±0. 19 vs 0. 71 ±0. 03, P lt;0. 01) . No difference on the mRNA expression of MFNG was found in the lung tissues( 1. 44 ±0. 29 vs 1. 70 ±0. 44, P gt; 0. 05) . MFNG mRNA expression decreased in the asthmatic group compared with the control group in the T cells( 1. 17 ±0. 04 vs 0. 68 ±0. 07, P lt;0. 05) . The results of western blot were consistent with RT-PCR results of the lung tissues. The expressions of RFNG increased in the asthmatic group( 1. 17 ±0. 04 vs 0. 68 ±0. 07, P lt;0. 05) . The expression of MFNG has no difference between two groups( 8. 10 ±0. 60 vs 9. 12 ±0. 07, P gt;0. 05) . LFNG had a lower expression in the asthmatic group( 4. 11 ±0. 38 vs 6. 41 ±0. 11, P lt; 0. 05) . Conclusion The abnormal expressions of three kinds of Fringe may be involved in the pathogenesis of asthma.

ObjectiveTo summarize strategy of diagnosis and treatment of thrombotic iliac vein stenosis in recent years.MethodThe relevant literatures in recent 5 years on the current status and trend of diagnosis and treatment of the thrombotic iliac vein stenosis were reviewed.ResultsAt present, the diagnostic methods of thrombotic iliac vein stenosis mainly included that the multi-slice spiral CT, venography, intracavitary ultrasound, magnetic resonance imaging, color Doppler ultrasound and other imaging examinations, each of which had its advantages and disadvantages. There were still no uniform criteria whether a filter should be placed, whether the stents should and how to be placed, and when to intervene in the patients with acute thrombotic iliac vein stenosis. There was no definite conclusion when and how to effectively intervene in the patients with chronic thrombotic iliac vein stenosis.ConclusionsIncidence of thrombotic iliac vein stenosis is high and sequela is severe. Early diagnosis and reasonable treatment are very important. Only strictly grasping indications, combining medical technology and patient’s condition, and adopting appropriate treatment strategy, can make patients’ maximal benefit.
ObjectiveTo evaluate the relationship between the genes involved in regulating iron uptake and maintaining iron homeostasis in Klebsiella pneumoniae from different sources and pathogenicity.MethodsThe genomic DNA sequences of two strains of Klebsiella pneumoniae from different sources were sequenced, stitched together, annotated and analyzed by second generation sequencing technique. The transversal comparison between different types of Klebsiella pneumoniae in NCBI database of iron carrier gene cluster iroB/C/D.ResultsIn these two Klebsiella pneumoniae clinical strains, the strain isolated from liver abscess patient carried 11 different iron acquisition and transportation system specific genes, which were not found in the non-liver abscess patient strain. Combined with the analysis of this sequence, in the NCBI database, six different strains of Klebsiella pneumoniae showed iroB/C/D triple positive.ConclusionIron acquisition and transportation system in Klebsiella pneumoniae may be an important pathogenic factor, which is closely related to hepatic abscess.
ObjectiveTo investigate the mental state of people during the outbreak of coronavirus disease 2019.MethodsA survey was conducted on 2 141 subjects using the anxiety and terror subscales of the 90-item symptom self-rating scale and a self-designed questionnaire by internet.ResultsThe anxiety level of the subjects in epidemic situation were slightly worse than the national average level in the normal period, and the terror level of the subjects in epidemic situation were extremely worse than the national average level in the normal period (P<0.05). The mental state of the subjects showed significant differences in gender, age, source and Wuhan contact history. There was a significant positive correlation between epidemic information and anxiety, fear and sleep status of subjects. The anxiety and fear levels of subjects with the cognitive tendency of systems thinking were significantly lower than other subjects (P<0.05).ConclusionsStress responses have emerged in the population during the outbreak of coronavirus disease 2019, mainly caused by the epidemic events directly threatened the health and safety of life. People need timely mental support provided by public emergency management.
Objective To investigate the value of thyroid stimulating hormone (TSH) inhibition therapy in postoperative patients with differentiated thyroid carcinoma. Methods One hundred and six patients with differentiated thyroid carcinoma after total or near-total thyroidectomy were divided into two groups: TSH inhibition therapy group and thyroid hormone replacement therapy group. The non-recurrence and (or) non-metastasis rate in two groups was analyzed retrospectively by Wilcoxon statistical analysis. Results The non-recurrence and (or) non-metastasis rate of 3-， 5- and 10-year in TSH inhibition therapy group were 98.31%， 92.41% and 75.45% respectively， and were higher than those (93.57%， 84.18% and 52.06% respectively) in thyroid hormone replacement therapy group （P=0.046 5）. Conclusion TSH inhibition therapy after total or near-total thyroidectomy may be an essential treatment for differentiated thyroid carcinoma patients.
Speech imagery is an emerging brain-computer interface (BCI) paradigm with potential to provide effective communication for individuals with speech impairments. This study designed a Chinese speech imagery paradigm using three clinically relevant words—“Help me”, “Sit up” and “Turn over”—and collected electroencephalography (EEG) data from 15 healthy subjects. Based on the data, a Channel Attention Multi-Scale Convolutional Neural Network (CAM-Net) decoding algorithm was proposed, which combined multi-scale temporal convolutions with asymmetric spatial convolutions to extract multidimensional EEG features, and incorporated a channel attention mechanism along with a bidirectional long short-term memory network to perform channel weighting and capture temporal dependencies. Experimental results showed that CAM-Net achieved a classification accuracy of 48.54% in the three-class task, outperforming baseline models such as EEGNet and Deep ConvNet, and reached a highest accuracy of 64.17% in the binary classification between “Sit up” and “Turn over”. This work provides a promising approach for future Chinese speech imagery BCI research and applications.
ObjectiveTo systematically review the influence of childhood psychosocial stress on pubertal emotional and behavioral problems. MethodsThe PubMed, OVID, EBSCO, Web of Science, CBM, VIP, WanFang Data and CNKI databases were electronically searched to collect studies on the relationships between childhood psychosocial stress and pubertal emotional and behavioral problems from inception to February 29, 2024. Two reviewers independently screened the literature, extracted data and assessed the risk of bias in the included studies. Qualitative methods were then used to analyze the data. ResultsA total of 41 cohort studies were included. The outcomes of 19 studies involved pubertal emotional problems, 26 studies involved behavioral problems, and 7 studies involved overall problems. The results showed that depression (14/19) and anxiety (8/19) were the most commonly reported emotional behaviors. Most studies (17/19) showed that childhood psychological stress had a positive predictive effect on pubertal emotional problems. Behavioral problems involved many outcomes, including smoking, drinking, illegal substance use, self-injurious behavior, suicide, externalizing behavior, criminal behavior, bullying behavior, sexual behavior, mobile phone dependence, etc. However, few studies were on the same behaviors, and the relationship between childhood psychosocial stress and behavioral problems was unclear. ConclusionChildhood psychosocial stress may have a positive predictive effect on depression and anxiety. The associations between childhood psychosocial stress and pubertal behavioral problems and other emotional problems remain to be determined by more studies.
