Objective To investigate the magnetic resonance imaging (MRI) and computerized tomography (CT) imaging findings of hepatic angiomyolipoma (AML).Methods Twelve cases of hepatic AML,which were confirmed by pathologists between 2009 and 2011 in our hospital,were retrospectively analyzed.Results There were 3 males and 9 females with an average age of 44.17 years (range,34 to 60 years).There were 14 lesions,8 in left lobe,6 in right lobe.All of 12 cases were confirmed as angiomyolipoma by pathologists.Nine cases were performed with MRI,2 with CT,and 1 with both CT and MRI.The border of lesions were clear in 8 cases.Fat contents were shown on CT and/or MRI in 8 cases.After administrated with contrast medium,the lesion enhancement was still apparent or slightly decreased in 9 lesions from portal phase to delayed phase.The suppression of portal vein and inferior vena cava by tumor were seen in 5 lesions.Abnormal vascular distortion was seen in 6 lesions.None of 12 lesions were found with portal vein thrombosis.Conclusion The diagnosis of hepatic angiomyolipoma should be considered when CT and MRI show good boundaries,intratumoral fat content,delayed lesion enhancement,and vascular distortion.

Objective To assess the role of the ferroptosis-associated gene GLS2 in the prognosis of pan-cancer and immunity using bioinformatics methods. Methods GLS2 expression levels in pan-cancer were profiled using publicly available databases: The Cancer Genome Atlas, GTEx, Cancer Cell Line Encyclopedia and the International Cancer Genome Consortium. The aim was to explore the role of GLS2 gene expression, gene variation survival analysis, immune infiltration, immune checkpoint related genes, TMB, and MSI in different tumors. Results Difference in GLS2 expression levels between cancer and paraneoplastic tissues was statistically significant in most cancer types, and the expression level was correlated with survival in these cancer types. A positive correlation was found between GLS2 expression and immune cell infiltration in multiple cancer types, and GLS2 expression level was positively correlated with TMB, MSI, and methylation, and its expression is an indicator for potential therapeutic response. Conclusion Pan-cancer analysis shows that the ferroptosis-related gene GLS2 can be used as a diagnostic and prognostic marker of clear cell carcinoma of kidney, adrenocortical carcinoma, lung adenocarcinoma, and pancreatic cancer.

Objective? To explore the effects of solution-focused approach on negative emotion and gastrointestinal symptom in patients with hepatogenic diarrhea. Methods Totally 86 patients with hepatogenic diarrhea admitted in the First Affiliated Hospital of Zhengzhou University from January to December 2018 were selected using convenient sampling and divided into control (n=39) and observation (n=47) groups according to the time of admission. Patients in the control group received conventional nursing care, while patients in the observation group received 5-step intervention based on solution-focused approach. Self-Anxiety Scale (SAS), Self-Depression Scale (SDS) and Gastrointestinal Symptom Rating Scale (GSRS) were used to assess the effects of intervention. Results? After intervention, the SAS, SDS and GSRS scores of the observation were lower than those of the control group, and there were statistically significant differences between the two groups (P＜0.05). The top 5 gastrointestinal symptoms in both groups were stomachache, poor stool output, frequent defecation, loose stools and fecal urgency. The incidence of sour regurgitation, abdominal pain, flatulence, poor stool output and frequent defecation, loose stools and fecal urgency was reduced after intervention in the observation group, and there were statistically significant differences between the two groups (P＜0.05). Conclusions? Solution-focused approach can ameliorate negative emotions such as anxiety and depression as well as gastrointestinal symptoms in patients with hepatogenic diarrhea, which is worthy promoting in clinical practice.

Ferroptosis is a novel regulatory cell death characterized by iron dependence and mainly caused by the accumulation of lipid peroxides and reactive oxygen species in the cell. This process plays an important role in the development of many malignancies, and has been extensively studied in lung cancer, especially in antitumor therapy. In recent years, the role of ferroptosis in tumor immunotherapy has been gradually explored. Studies showed that targeting ferroptosis can improve the therapeutic efficacy of antitumor immunotherapy. In addition, immunotherapy and ferroptosis can work synergistically to enhance the effectiveness of antitumor therapy, suggesting a potential relationship between ferroptosis and immunotherapy and the possible reversal of immune drug resistance. This study aims to elucidate the characteristics of ferroptosis, and the role and potential clinical applications of ferroptosis in the antitumor immunotherapy of advanced non-small cell lung cancer. We also explore the role of some nanomaterials that target the onset of tumor ferroptosis in facilitating immunotherapy.

Objective To investigate the demand for perioperative health education in liver transplantation patients at different stages, and to discuss its influencing factors, so as to provide the empirical evidence for nurses to satisfy patients' health education demand. Methods From July 2014 to March 2016, the self-designed health education demand questionnaire for patients undergoing liver transplantation was used to investigate 71 patients who met the criteria. Single factor analysis and multiple regression analysis were used to explore the influencing factors of the health education demand. Results The score of health education demand in liver transplantation patients was (114.48±5.27), which was at a relatively high level. The item with highest demand at preoperative stage was the financial burden of the surgery, with the score of (4.52±0.81). Diet guidance was the highest at postoperative stage, and the score was (4.61±0.57). Before discharge, review follow-up guidance was the most popular item, with the score of (4.72±0.45). Multiple regression analysis demonstrated that education background and waiting time for liver were the main influencing factors of health education demand (P<0.05). Conclusions The nursing staff should realize the current situation of health education demand in liver transplantation patients and provide individualized health education for each individual patient to improve the patients' quality of life.

Objective:To explore the mediating effect of emotional exhaustion of nurses on occupational stress and recovery experience, so as to provide reference for clinical nursing management.Methods:From June to August 2019, clinical registered nurses of the First BethuneHospital of Jilin University were selected as the research objects by convenient sampling method. Occupational Stress Inventory (OSI-R) , emotional exhaustion subscale of Maslach Burnout Inventory-General Survey (MBI-GS) and Recovery Experience Questionnaire (REQ) were used to investigate and analyze the correlation between occupational stress, emotional exhaustion and recovery experience of clinical nurses. In this study, a total of 560 questionnaires were issued and 538 valid questionnaires were recovered, with an effective recovery rate of 96.1%.Results:The total OSI-R score of 538 clinical nurses was (350.60±68.80) , the emotional exhaustion subscale score of MBI-GS was (22.65±7.05) and the total score of REQ was (51.16±12.20) . The occupational task, individual stress response and individual coping resource dimension scores of clinical nurses in REQ were all correlated with the total score of emotional exhaustion subscale ( P<0.05) , but negatively correlated with the total score of REQ ( P<0.05) . The relationship model of occupational stress, emotional exhaustion and experience recovery showed that occupational stress of clinical nurses had direct and indirect effects on experience recovery. Conclusions:There is a certain correlation between occupational stress, emotional exhaustion and recovery experience of nurses, and emotional exhaustion plays a mediating role between occupational stress and recovery experience. Nursing managers should provide a good working environment for clinical nurses, reduce occupational stress of clinical nurses, and reduce the level of emotional exhaustion to improve recovery experience of nurses.

Objective: To explore the association between middle school students health literacy and bully victimization and associated sex difference, and to provide guidance for bully prevention in adolescents. Methods: During November 2017 to January 2018, 18 900 junior and senior high school students were enrolled from Hefei of Anhui Province, Shenyang of Liaoning Province, Yangjiang of Guangdong Province and Chongqing by multistage cluster sampling. A self rated questionnaires were used to collect demographic information, health literacy, and bully victimization. Group differences by different characteristics and the association between health literacy and bully victimization were analyzed. Results: The detection rates of campus and cyber bullying victimization were 15.8% (2 992/18 900) and 9.1% (1 723/18 900). Boys, junior high school students, students with poor family financial status and few close friends had a detection rate of 28.0%, 18.8%, 23.3%, and 33.6% of school bullying, which are higher than those of the control group ( χ 2=225.64, 148.07, 141.13, 143.49, P <0.01); boys, students with poor household income and few close friends, the detection rates of cyber bullying were 10.9%, 14.4%, and 20.1%, respectively, are higher than the control group ( χ 2=62.96, 112.82, 88.49, P <0.01). Multivariate Logistic regression analysis indicated that students with low overall and dimensions scores of health literacy were more likely to suffer from campus and cyber bullying, except for the dimension of physical activity. In addition, at all levels of health literacy, males are more likely to be bullied than females ( P <0.05). Conclusion Health literacy of middle school students is related to bully victimization, which is sex specific. Intervention programs of bullying should focus on health literacy enhancement.

Objective To investigate the diagnostic value of dynamic-extended focused assessment with sonography for trauma (D-EFAST) in patients with multiple trauma in intensive care unit (ICU). Methods A prospective clinical study was conducted. Eighty patients with multiple trauma admitted to ICU of Anhui Provincial Hospital from September 1st, 2014 to December 31st, 2016 were enrolled. Extended focused assessment with sonography for trauma (E-FAST) check was conducted at first, for those who had positive findings diagnosis was confirmed by immediately CT examination or surgical exploration. If it was negative, the patients received E-FAST every morning for 7 days (defined as D-EFAST), for those with positive findings, immediately CT or surgery was performed to clarify the diagnosis. The final clinical diagnosis was used as the "gold standard" to calculate the diagnostic accordance rate of EFAST and D-EFAST examination technique for pneumothorax, pleural effusion, spleen injury, kidney damage, liver damage, gastrointestinal injury, pericardial effusion, bladder rupture, and pancreatic injury, as well as their sensitivity, specificity, positive predictive value, negative predictive value, accuracy rate, and missed diagnosis rate, and the difference between EFAST and D-EFAST was compared. Results There were 4 patients excluded because of death and abandoning treatment, and finally 76 patients were included in the study. The total sensitivity of E-FAST examination technique for pneumothorax, pleural effusion, spleen injury, liver damage, gastrointestinal injury, pericardial effusion, and bladder rupture was 75.9% (66/87), and the specificity was 98.3% (587/597), the positive predictive value was 86.8% (66/76), and the negative predictive value was 96.5% (587/608), the accuracy rate was 95.5% (653/684), and the rate of missed diagnosis was 24.1% (21/87). The most of the delayed injury in patients with multiple trauma occurred at 2-7 days after injury with incidence of 4.8% (33/684). The diagnostic sensitivity of D-EFAST for delayed injury was 98.3% (118/120), the specificity was 99.8% (563/564), the positive predictive value was 99.2% (118/119), the negative predictive value was 99.6% (563/565), the diagnostic accuracy rate was 99.6% (681/684), and rate of missed diagnosis was 1.7% (2/120). When the final clinical diagnosis was set as the "gold standard", D-EFAST technology for the detection rate was 98.3% (118/120) for patients with multiple trauma on organ injury while the detection rate of E-FAST was 75.9% (66/87), with statistical significant difference (P < 0.01), indicating that D-EFAST was better than E-FAST in check of multiple trauma patients with organ injury. Conclusion Although the E-FAST technology can quickly diagnose the multiple trauma patients and win the rescue time for critical patients, multiple trauma patients injured after 2-7 days prone to delayed damage and are difficult to detect, and D-EFAST can be used to find delayed damage earlier, and reduce the misdiagnosis rate of multiple trauma patients.

Tongue diagnosis is one of the diagnostic methods of Traditional Chinese Medicine (TCM), but its development has always been restricted by the lack of objective quantitative indicators. With the rapid development of computer technology and the advent of the algorithm era, the modernization of TCM tongue diagnosis has gradually become a hot research spot. This paper annalyses the literature and related patents of the modernization of tongue diagnosis and summarizes the R&D progress and application of tongue diagnosis as well as related instruments. It is found that domestic and foreign scholars focus on tongue diagnosis related research and attach importance to the formulation of relevant international standards. Tongue collection and analysis technology continues to develop; tongue diagnostic instruments are also gradually enriched. At present, their applications are extended to family self-use, but they are still mainly used in teaching, scientific research and other fields, involving the clinical efficacy evaluation of TCM, clinical case classification and health management, and there is still much room for development. In the future, we should strengthen the communication between multi-regional research centers, promote the communication among talents in different fields, constantly make up for the deficiencies and promote the development of tongue diagnosis research.

Objective: To explore the association between health literacy and drinking behaviors among middle school students in six provinces of China, and to provide scientific basis for the prevention and intervention of drinking behaviors. Methods: From November 2015 to January 2016, 22 628 students were enrolled from Ulanqab, Shenyang, Xinxiang, Bengbu, Chongqing and Yangjiang by multistage stratified cluster sampling method. And a questionnaire survey was conducted among them to collect demographic information, health literacy and drinking behaviors. Rates on drinking behaviors were compared in students with specific characteristics. Multiple Logistic regression analyses were conducted to examine the association between health literacy and drinking behaviors. Results: The proportion of ever drinking, current drinking, binge drinking, drunkenness was 60.0%(13 580), 16.8%(3 799), 5.9%(1 344) and 9.9%(2 250), respectively. After adjusting for gender, grade, family address, siblings, accommodation type, parental educational level, and self reported family income, compared to the high level health literacy, the low level health literacy was significantly associated with ever drinking (OR=1.76, 95%CI=1.62-1.91), current drinking(OR=1.37, 95%CI=1.23-1.52), binge drinking (OR=1.39, 95%CI=1.18-1.63), and drunkenness(OR=1.68, 95%CI=1.47-1.92), respectively(P<0.01). Conclusion Health literacy of middle school students was related to drinking behaviors. The occurrence of health risk behaviors such as drinking can be prevented and reduced by improving students health literacy level.
