Visualization and Analysis of Infectious Disease Research on Nursing Care Based on CiteSpace in China.

Objective: To analyze the relevant research publications on infectious disease nursing in China to understand the current research status of infectious disease in nursing. Methods: Retrieve relevant literature on infectious disease in nursing from the establishment of the Chinese Biomedical Literature Database, China National Knowledge Infrastructure (CNKI), VIP Database, and Wanfang Database until May 10, 2021. Conduct bibliometric analysis using CiteSpace software. Key words were analyzed using cluster analysis. Results: A total of 4693 relevant literature on infectious disease research in nursing care were included in this study. The overall number of publications on infectious disease research in nursing showed an increasing trend, with a peak in 2010. There were 324 papers funded by scientific research funds, mainly from provincial-level fund projects. The core journal with the most published articles was Nursing Research. The research on infectious disease in nursing mainly focused on various aspects of infectious disease in nursing and infection control. CiteSpace cluster analysis of keywords showed that a total of six clusters were formed: infectious diseases, infectious disease care, health education, mental health, infectious disease nurses, and etiology. After 2015, high-mutation keywords included "quality nursing" and "infection control". Conclusion: Chinese research on infectious disease research in nursing closely follows clinical reality and has developed rapidly. Currently, research focuses on infectious disease research in nursing and infection control. Future research trends will further broaden the depth and breadth of the research, enhance research on infection control and quality nursing, and improve the breadth and depth of the research.

The stress of studying in China: primary and secondary coping interaction effects.

Answering the call for research on coping outside of the Western world, the present study confirms previous research that indicated Asians cope with stress differently from other ethnic groups. In the present study, we explore the stress-coping-adjustment model and its role in acculturation for educational sojourners in the People's Republic of China. Using a sample of 121 recent exchange students (Asian, n = 52; non-Asian, n = 69), we administered surveys in the Fall of 2013 and 90 days later to measure students' socio-cultural adaptation. Results indicate several significant findings. Acculturative stress and perceived cultural distance had no role in predicting adaptation. Non-Asians reported greater adjustment even though cultural distance was greater. As hypothesized, non-Asians used more primary and secondary coping compared to Asians. Moderation analyses indicate three-way interactions among stress × coping × group, showing that non-Asians benefit from high usage primary coping, while primary coping exacerbates the negative effects of stress on adjustment for Asians. Secondary coping proves to be beneficial for both groups and improves adjustment across low and moderate stress levels. Results support recent developments in collective coping, suggesting that primary and secondary coping may not be beneficial for all ethnic groups in all circumstances. Research implications and practical contributions are discussed.

Differentiation between malignant and benign nodules in the liver: use of contrast C3-MODE technology.

AIM: To investigate the value of contrast-enhanced C3-MODE technology in differentiating malignant nodules of liver from the benign ones. METHODS: Forty-six nodules in 36 patients (29 men and 7 women) were studied by contrast-enhanced C3-MODE technology and contrast-enhanced CT in 1 wk before the biopsy or operation. A low MI monitor and a high MI flash imaging were intermittently performed. After the injection of contrast agent, the period from 10 to 30 s and the time later than 100 s were respectively defined as early arterial phase and the late phase. The vascularities of the liver nodules in the two phases were combined for differential diagnosis. Corresponding to the pathological diagnosis, the accuracy, sensitivity and specificity of contrast-enhanced C3-MODE technology were compared to those of contrast-enhanced CT. RESULTS: By C3-MODE technology, 33 of the 46 liver nodules were demonstrated as defected area in the late phase and were diagnosed as malignant tumors. Of them, 28 with hypervascularity in the early arterial phase were assessed as hepatocellular carcinoma, the other five nodules with rim-like enhancement in the early arterial phase were diagnosed as metastatic tumors. Thirteen nodules were shown as iso or hypervascularity in the late phase as well as centripetal filling in the early arterial phase and we made a diagnosis of hemangioma. Corresponding to the pathological results, the sensitivity, specificity and accuracy of contrast-enhanced C3-MODE technology in differentiating malignant and benign nodules in the liver were 97.0%, 92.3% and 95.7%, respectively. With comparison to those of contrast CT (sensitivity, 94.1%; specificity, 91.7%; accuracy, 93.5%), the difference was not significant. CONCLUSION: Contrast-enhanced C3-MODE technology can effectively differentiate malignant liver tumors from the benign nodules. It highly agrees diagnostically with the pathology. We suggest that it provides a new approach for differential diagnosis of liver nodules in addition to contrast-enhanced CT.

Percutaneous ethanol injection, radiofrequency and their combination in treatment of hepatocellular carcinoma.

AIM: To evaluate the therapeutic effect and the indication of percutaneous ethanol injection (PEI), radiofrequency ablation (RFA) and their combination in treatment of hepatocellular carcinoma (HCC). METHODS: Two hundred and fifty-five patients with HCC received treatment of PEI, RFA or their combination. Group 1 (< 3 cm in diameter, n=85) was treated with PEI, group 2 (< 3 cm in diameter, n=153) with RFA. Group 3 (> 3 cm in diameter, n=86) was divided into two groups. Group 3a (n=34) was treated with RFA, while group 3b (n=52) was treated with RFA for 2 wk after transcatheter arterial chemoembolization or PEI. Contrast-enhanced sonography was performed for 61 patients before and after RFA. Liver function and serum alpha-fetoprotein (AFP) were measured for all patients. Changes of the lesions on ultrasound and contrast-enhanced CT/MRI were evaluated for assessing the therapeutic responses. The 1-, 2-, 3- and 5-year survival rates were recorded after treatment. RESULTS: In group 1, the complete necrosis rate of lesions after 1 mo was 77.6% (66/85). The level of AFP declined conspicuously after 1 mo. The 1-, 2-, 3- and 5-year survival rate after treatment was 80.0% (52/65), 60.4% (32/53), 52.5% (21/40) and 33.3% (7/21), respectively. In group 2, the complete necrosis rate of lesions after 1 moh was 92.2% (141/153). The level of AFP decreased conspicuously after 1 mo. The 1-, 2-, 3- and 5-year survival rate after treatment was 94.6% (88/93), 73.2% (52/71), 63.5% (33/52) and 46.4% (13/28), respectively. In group 3a, the complete necrosis rate of lesions after 1 mo was 23.5% (8/34). AFP dropped down to the normal level in only one patient after 1 mo. The 1-, 2- and 3-year survival rate after treatment was 47.6% (10/21), 42.9% (6/14) and 27.3% (3/11), respectively. Only one patient was still alive after 5 years. In group 3b, the complete necrosis rate of lesions after 1 mo was 57.7% (30/52). The level of AFP decreased after 1 mo. The 1-, 2-, 3- and 5-year survival rate after treatment was 68.6% (24/35), 46.2% (12/26), 36.8% (7/19) and 27.3% (3/11), respectively. CONCLUSION: The therapeutic effect of RFA on small HCC is better than that of PEI. Small HCC is the optimal indication of RFA. For recurrent HCC (diameter > 3 cm), the combined treatment of RFA and PEI/ACE should be used.
