Methods: The expression of KDM5B in normal liver, HCC and its adjacent tissues was analyzed by RT-PCR and IHC. Lentivirus transfection method was used to construct stable cell lines with KDM5B overexpression and down-regulation, and the role of KDM5B in HCC migration and invasion was detected at cell level and animal level. Western blotting and Transwell experiments were performed to verify the effect of KDM5B and/or CCR2 inhibitors on HCC progression and metastasis by using liver orthotopic transplantation tumor model and immunofluorescence methods. Results: RT-PCR showed that the expression level of KDM5B in HCC was significantly higher than that in adjacent tissues, and the increase of KDM5B was relatively significant. Upregulation of KDM5B in nude mouse liver orthotopic transplantation tumor model can promote the incidence of lung metastasis and shorten the survival time of nude mice, whereas upregulation of KDM5B can reduce the incidence of lung metastasis and prolong the survival time of nude mice. Conclusion: This study clarified the expression of KDM5B in HCC and its function in promoting HCC migration, invasion and metastasis. The molecular mechanism of KDM5B promoting HCC metastasis was revealed, providing a potential therapeutic target for HCC.展开更多

Childhood physical and mental trauma is the key reason for the development of many serious diseases. Severe traumatic events can cause Post-Traumatic Stress Disorder (PTSD). Children’s psychological adjustment and tolerance are generally lower than adults, and it is difficult for children to seek reasonable help after suffering traumatic events. Children who experience a traumatic event have an even higher rate of PTSD than adults, considering problems with their symptom presentation. Post-Traumatic Stress Disorder can hinder children’s development of healthy psychology such as independence and autonomy in the future, and can lead to a series of psychological disorders in adulthood. This article introduces the epidemiology, symptoms, physiological changes and influencing factors of PTSD in children, and puts forward the direction of treatment in the future.展开更多

The...The diagnosis of pathogenic bacteria in severe pneumonia is difficult and the prognosis is poor. Its outcome is closely related to bacterial pathogenicity and the timeliness and pertinence of antibiotic treatment. Therefore, early diagnosis is of great significance to the prognosis of patients. Sputum examination and culture is the gold standard for the diagnosis of pathogens of severe pneumonia. However, due to the long time of bacterial culture, the early use of antibiotics, the change of bacteria species, mixed infection and other problems, the results of bacterial culture in sputum are often false negative. With the continuous application of new molecular biology techniques in clinical detection, the classification of bacteria and microorganisms has deepened from the identification of phenotypic characteristics to the classification of gene characteristics. Sequencing analysis with 16S rDNA sequencing technology has the characteristics of high sequencing flux, large amount of data obtained, short cycle, and can more comprehensively reflect the species composition of microbial community, real species distribution and abundance information. In this paper, 16S rDNA sequencing technology was used to analyze the bacterial population composition in the sputum of severe pneumonia, and to explore a new method of etiological diagnosis.展开更多

In China, the incidence of diabetes is on the rise, the cure rate of diabetes is low, patients with complications are more, and diabetes patients bring a heavy economic burden to the family and society. <span "="">Compared with developed countries, China still has a big gap in terms of diabetes care, education and management, and even less long-term follow-up of diabetes education and management results. Therefore, the management of diabetic patients should not only stay in the intervention during hospitalization, but also extend to the outside of the hospital. Only by implementing the whole-process nursing case management integrating hospitalization</span>-family/community-outpatient, can diabetic patients better control blood glucose, delay or prevent the occurrence of chronic complications, and improve their quality of life. The nursing work method of case management is adopted to carry out personalized assessment for diabetes patients, design the process of initial outpatient consultation, content and process of follow-up consultation for nurses, and implement personalized guidance. The diabetic complications should be screened regularly, diabetes management should be standardized, self-care ability and behavior compliance of treatment and nursing of diabetic patients should be improved, and comprehensive whole-process nursing management should be provided for every diabetic patient, so as to improve the quality of life of patients and truly benefit diabetic patients.展开更多

文摘Childhood is an important period for personality formation, cognition and social development. Childhood physical and mental trauma is the key reason for the development of many serious diseases. Severe traumatic events can cause Post-Traumatic Stress Disorder (PTSD). Children’s psychological adjustment and tolerance are generally lower than adults, and it is difficult for children to seek reasonable help after suffering traumatic events. Children who experience a traumatic event have an even higher rate of PTSD than adults, considering problems with their symptom presentation. Post-Traumatic Stress Disorder can hinder children’s development of healthy psychology such as independence and autonomy in the future, and can lead to a series of psychological disorders in adulthood. This article introduces the epidemiology, symptoms, physiological changes and influencing factors of PTSD in children, and puts forward the direction of treatment in the future.
文摘Objective: To analyze the correlation between Val66Met gene of brain-derived neurotrophic factor (BDNF) and papillary thyroid carcinoma (PTC) complicated with depression. To evaluate the clinical value of papillary thyroid carcinoma. Methods: Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were used to assess the correlation of BDNF in the blood of patients with depressive disorder of thyroid papillary carcinoma using polymerase chain reaction PCR. The relationship between BDNF gene polymorphism and the incidence of thyroid papillary carcinoma was analyzed, and the susceptibility factors of thyroid papillary carcinoma complicated with depression were explored. Results: Compared with normal control group, T3 and T4 of PTC in non-depressed group were decreased, while TSH and TPOAb were increased (P < 0.05). Compared with normal control group, T3, T4 and TPOAb were increased and TSH was decreased in PTC depression group (P < 0.05). PTC depression score was higher than that of healthy control group (P < 0.05), and PTC combined depression score was higher than that of normal control group (P < 0.05). The depression rate of PTC combined with depression was 86.7%, which was higher than that of other groups (P < 0.05). The distribution of RS6265 locus genotype of BDNF gene was significantly different between PTC with depression group and PTC without depression group (P Conclusion: There is a significant difference between PTC with depression and PTC without depression, which is related to SNP rs6265 of BDNF gene. AG and GG are both risk sites of PTC with depression, and GG type is more prone to PTC with depression.
文摘<b>Objective:</b> 120 patients with severe pneumonia who were kept in the comprehensive ICU of our hospital in 2018 were selected, and 16s rDNA sequencing was performed to analyze the composition of pathogenic bacteria in the sputum of severe pneumonia. <b>Methods:</b> The sputum samples of patients with severe bacterial pneumonia were collected, and the diversity of pathogens in the samples was analyzed by polymerase chain reaction (PCR) amplification and high-throughput sequencing (16s rDNA PCR-DGGE). <b>Results:</b> Sequence showed that sputum samples contained a relatively large number of species, and there were many species that were not detected by sequencing. The dominant bacteria were <i>Streptococcus, Sphingomonas, Corynebacterium, Denatobacteria, Aquobacteria, Acinetobacteria, Prevotella, Klebsiella, Pseudomonas</i>, etc. <b>Conclusion:</b> Bacteria caused by sputum of severe bacterial pneumonia are complex and diverse, which provides new methods and ideas for individualized treatment of patients with severe pneumonia.
文摘The diagnosis of pathogenic bacteria in severe pneumonia is difficult and the prognosis is poor. Its outcome is closely related to bacterial pathogenicity and the timeliness and pertinence of antibiotic treatment. Therefore, early diagnosis is of great significance to the prognosis of patients. Sputum examination and culture is the gold standard for the diagnosis of pathogens of severe pneumonia. However, due to the long time of bacterial culture, the early use of antibiotics, the change of bacteria species, mixed infection and other problems, the results of bacterial culture in sputum are often false negative. With the continuous application of new molecular biology techniques in clinical detection, the classification of bacteria and microorganisms has deepened from the identification of phenotypic characteristics to the classification of gene characteristics. Sequencing analysis with 16S rDNA sequencing technology has the characteristics of high sequencing flux, large amount of data obtained, short cycle, and can more comprehensively reflect the species composition of microbial community, real species distribution and abundance information. In this paper, 16S rDNA sequencing technology was used to analyze the bacterial population composition in the sputum of severe pneumonia, and to explore a new method of etiological diagnosis.
文摘In order to understand the psychological problems of pregnant women, this article explores the psychological problems and the sources of psychological stress of pregnant women who have a history of recurrent miscarriage after pregnancy. The analysis shows that the psychological stress of pregnant women may be one of the reasons for recurrent miscarriage. Strengthening mental health education during pregnancy can avoid the stimulation of bad emotions and environment, prevent the spontaneous abortion caused by psychological reasons, and improve the quality of pregnancy. It is particularly important to grasp the mental state of pregnant women with recurrent abortion timely and carry out corresponding psychological counseling and psychological nursing.
文摘Diabetes is the world’s third largest threat to people’s health. In China, the incidence of diabetes is on the rise, the cure rate of diabetes is low, patients with complications are more, and diabetes patients bring a heavy economic burden to the family and society. <span "="">Compared with developed countries, China still has a big gap in terms of diabetes care, education and management, and even less long-term follow-up of diabetes education and management results. Therefore, the management of diabetic patients should not only stay in the intervention during hospitalization, but also extend to the outside of the hospital. Only by implementing the whole-process nursing case management integrating hospitalization</span>-family/community-outpatient, can diabetic patients better control blood glucose, delay or prevent the occurrence of chronic complications, and improve their quality of life. The nursing work method of case management is adopted to carry out personalized assessment for diabetes patients, design the process of initial outpatient consultation, content and process of follow-up consultation for nurses, and implement personalized guidance. The diabetic complications should be screened regularly, diabetes management should be standardized, self-care ability and behavior compliance of treatment and nursing of diabetic patients should be improved, and comprehensive whole-process nursing management should be provided for every diabetic patient, so as to improve the quality of life of patients and truly benefit diabetic patients.
