BACKGROUND:To evaluate the psychological characteristics of the patients waiting for renal transplantation in order to analyze coping style, thus perform the corresponding personalized clinical psychological intervention which is conductive for patients to face reality and disease. OBJECTIVE:To investigate the psychological characteristics of the patients waiting for renal transplantation and to analyze the effect of different social factors on the coping style of patients and to explore the corresponding clinical mental intervention method METHODS:Fifty-eight patients waiting for renal transplantation and 60 patients without renal transplantation were randomly selected from Second Department of Urology, Organ transplantation Center, the 309th Hospital of PLA between February 2009 and August 2010, the patients were required to fil in a psychological questionnaire form using the currently general used medical response. The effect of social factors on the coping style and psychological stress status was analyzed with multi-factor Logistic regression analysis. RESULTS AND CONCLUSION:From the questionnaire survey, the evasive and yielding value scores of the patients waiting for renal transplantation were significantly higher than those of the patients without renal transplantation (P<0.05), but there was no significant difference of confrontation score between the patients (P>0.05). It indicated that the psychological pressure of the patients waiting for renal transplantation was bigger that of the patients with out renal transplantation, which may related with course of the disease, cost and the rejection after transplantation for the patients has to endured. Multi-factor Logistic regression analysis showed that sex, education, income, payment methods and age of the patients were al related with the confrontation, evasive and yielding scores, as those with technical secondary school education or better got the best confrontation score while those with annual income less than 60 000 yuan got the highest score in evasive and yielding styles. The results show that income and education level of patients are the main factors that affect the coping style and psychological stress status of the patients waiting for renal transplantation, treating the patients with reasonable renal clinical care interventions can help the patients face to the disease positively and can reduce the damage of transplantation to the psychology of the patients.

The stability of cell genetic material is influenced by a variety of factors, both internal and external, which can cause various types of DNA damage, such as DNA alkylation, oxidation, mismatching, loop structure, atypical DNA structure, single-strand break, and double-strand break.These DNA damages disrupt cellular homeostasis and dynamic equilibrium, which cause gene mutations, chromosomal abnormalities, and even degradation, aging, and death at different biological levels.By searching and identifying DNA damage sites, the cell activates a series of biochemical pathways, coordinates the progress of DNA replication and transcription, and then repairs the DNA damage.In this way, the cell maintains its independence and stability.While radiotherapy plays a role in eliminating tumors by DNA damages, it also initiates DNA damage responses.Among the responses, base excision repair, nucleotide excision repair, mismatch repair, double-strand break repair, and post-translesion synthesis repair play a key role in repairing the damages.The dysfunction of these repair pathways will cause differences in tumor radiation sensitivity.This paper summarizes recent research results in DNA damage repair, and focuses on the types of DNA damage and their repair mechanisms, so as to promote the understanding of the great significance of this field and to provide a theoretical basis for exploring the application of DNA damage repair pathways in tumor therapy.
