Status quo and hot spots in studies on family caregivers:a bibliometric analysis / 中华医学图书情报杂志

Objective To analyze the status quo and hot spots in studies on family caregivers by bibliometric analy-sis. Methods PubMed-covered papers on family caregivers from 2011-01-01 to 2016-07-01 were retrieved and analyzed by BICOMS and gCLUTO to generate subject heading clustering curve, subject heading clustering matrix and subject heading tree. Results Six hot spots were detected in studies on family caregivers from 4945 papers from which 82 subject headings were extracted with a frequency≥36 , including social and psychological intervention of family caregivers for ischemic stroke patients, intervention of family caregivers for mental disease patients, mental health of family caregivers, mental health intervention of family caregivers for PD patients, mental health of family caregivers for AIDS patients, and mental health of family caregivers for tumor patients. Conclusion Importance is attached to the studies on family caregivers by foreign and domestic scholars with their studies focused on the inves-tigation and intervention of mental health in family caregivers.

Latent class analysis on resilience characteristics of empty-nest elderly in community / 中华行为医学与脑科学杂志

Objective To analyze the characteristics of resilience among empty-nest elderly in community with exploratory latent class analysis method and provide a basis for making targeted intervention measures according to different characteristics.Methods This study enrolled 203 empty-nest elderly people as the study respondents.The general information,resilience of empty-nest elderly were investigated using the general information questionnaire,Connor-Davidson resilience scale in Chinese version.Latent class analyze (Mplus 7.0) was used to discuss the characteristics of resilience among empty-nest elderly.Results The results showed that the resilience of empty-nest elderly had obvious group characteristics and the statistical indicators(AIC,BIC,Entropy and so on) can support the three categories of potential model(P=0.006).Based on the conditional probability on the various items of the questionnaire in each category,they were respectively named high resilience group (54 cases (26.6％)) and low pressure resilience group (82 cases (40.4％)) and low resilience group(67 cases (33.0％)).Further study showed that high resilience and low resilience group had a significant effect of age (P＜0.05),low pressure resilience and low resilience group had a significant effect of gender(P＜0.05).Conclusion The resilience of empty-nest elderly in communities can be divided into three categories according to its characteristics.Each category has different proportion of gender and age.

Prognostic Significance of Expression of Glutathione S-Transferase-pi and Multidrug Resistance-Associated Protein in Nasopharyngeal Carcinoma / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: For the treatment of nasopharyngeal carcinoma (NPC), radiation therapy is a primary option. Because of distant metastasis and the high incidence of a locoregional failure following radiotherapy, the combined treatment modality with chemotherapy is applied, although resistance to chemotherapy makes chemotherapy less effective. The Cisplatin-based chemotherapy has been widely used in the field of nasopharyngeal cancer. The Cisplatin resistance is known to be caused by the multidrug resistance-associated protein (MRP), which is one of the drug-export pumps and the glutathione S-transferase (GST)-pi which catalyzes the conjugation of the GSH (glutathione) and the cisplatin. The aim of this study is to determine the predictive value of GST-pi and MRP upon the response to cisplatin in nasopharyngeal carcinoma. SUBJECTS AND METHOD: We analyzed tumor tissues from 49 cases of paraffin block specimens which were diagnosed with NPC and treated at Chonnam National University Hospital. The immunohistochemical study for the GST-pi and the MRP was performed with paraffin block specimens of nasopharyngeal cancers. RESULTS: In the GST-pi, the relationship between the early stage (64.3%) and the advanced stage (91.4%) was statistically significant (p=0.020). The expression of the GST-pi and the MRP had no relationship with the clinical factor, the response to chemotherpy and the survival rate. CONCLUSION: Because the expression of the GST-pi and the MRP in the nasopharyngeal carcinoma could not predict the response to chemotherapy. So the efforts to find the predictive value of the chemotherapy are needed.

Prognostic Significance of the Microvessel Density in Nasopharyngeal Carcinoma / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The nasopharyngeal cancer (NPC) of nasopharyngeal neoplasms is a rare disease with a relatively poor prognosis, because they tend to be diagnosed in the far advanced stage. Therefore, radiotherapy had been the treatment of choice. Angiogenesis is a crucial step in the tumor growth and progression. The authors attempted to investigate the prognostic value of the microvessel density in NPC. SUBJECTS AND METHOD: We analyzed tumor tissues from 57 cases of paraffin block specimens which had been diagnosed with NPC and treated at Chonnam National University Hospital. The anti-human von Willebrand factor antibody was used to determine the microvessel density (MVD). RESULTS: The MVD was 48.5 in the early stage (stage I and II) and 51.2 in the advanced stage (stage III and IV), which were not statistically significant (p=0.057). The MVD was 55.3 in type I, 54.4 in type II, and 41.8 in type III, and there were no statistical significance between these values (p=0.36). The MVD was not statistically significant between T and N stages (p=0.26, 0.42). There was no significance between the MVD and the survival rates (p>0.05). CONCLUSION: The results suggest that the MVD was not a prognostic significance in NPC.

Prognostic Significance and Treatment Outcomes of Combination of Radiotherapy and Chemotherapy in Nasopharyngeal Cancer / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: T he diagnosis of a nasopharyngeal carcinoma is frequently made at an advanced stage. The anatomic complexicity of the nasopharynx makes a surgical approach difficult, so the radiation therapy is traditionally used as a primary option. Because of the high incidence of a locoregional failure following the radiotherapy and the distant metastasis, the combined treatment modality with the chemotherapy has been applied. The author attempted to investigate the clinical characteristics and the treatment outcomes of nasopharyngeal cancer patients treated with the combination of the radiotherapy and the chemotherapy. SUBJECTS AND METHOD: We retrospectively analyzed 82 patients who were diagnosed with the nasopharyngeal carcinoma in Chonnam National University Hospital. RESULTS: The cumulative survival rates for a 5-year period were 42%. The pathologic type, the clinical stage, the cranial nerve invasion, and the response to the radiotherapy were related to the survival rate of the Kaplan-Meier test (p<0.05). In the Cox proportional hazard model, only the response to radiotherapy was related to the survival rate (p=0.05), as the clinical stage wasn't (p=.06). In the multivariate analysis between the responses to radiation and the clinical factor, the histological type (p=0.018) and the response to the chemotherapy (p=0.021) was statistically significant. CONCLUSION: The response to radiation is the most important in the patient's survival. The clinical stage is a probable prognostic factor. Factors affecting the response to radiation are the histological type and the response to chemotherapy.
