Objective To understand the current situation and motives of patients xeroxing medical records and the various factors affecting patients' right to know. Methods A cross-sectional survey was made on people who xeroxed medical records with self-made questionnaires and methods of descriptive analysis and stepwise regression analysis were then used to analyze 306 returned questionnaires. Results 98.37% of those surveyed showed approval for the procedures regarding the xeroxing of medical records; 98.04% felt satisfied with the hospital's medical records control; and the chief motives of patients xeroxing medical records were data keeping (28.57%) and medical insurance(27.12%). The current state of knowledge possessed by people xeroxing medical records about patients' rights was unsatisfying. Conclusion Patients' awareness of their right to xerox medical records and their satisfaction towards the hospital's medical records control are fairly high, and yet efforts still need to be made to step up propaganda among rural and elderly people.

【Objective】 To analyze the correlation between the expressions of ZEB1, androgen receptor (AR), E-cadherin (E-Ca), N-cadherin (N-Ca) and clinicopathological features of prostate cancer patients with different risk levels, and to explore their significance. 【Methods】 The clinical data of 47 patients with prostate cancer treated during Nov.2013 and Jun.2021 were retrospectively analzyed. The patients were divided into medium-low risk group and high-risk group. The expressions of ZEB1, AR, E-Ca and N-Ca in the prostate cancer tissues of the two groups were detected with immunohistochemical staining. The relationship between the expressions and Gleason grade, prostate-specific antigen (PSA) level and TNM stage was analyzed. 【Results】 The positive expression rate of ZEB1 increased with higher risk, Gleason score, and PSA level (P<0.01); the strong positive expression rate of AR decreased with higher risk and Gleason score (P<0.05); the positive expression rate of E-Ca decreased with increased risk, Gleason score, and PSA level (P<0.05); the positive expression rate of N-Ca increased with the increased risk and Gleason score (P<0.01); the positive expression rate of ZEB1 increased with higher tumor stage and TNM stage (all P<0.01); the strong positive expression rate of AR decreased only with increased TNM stage (P<0.05). Patients whose first surgical specimen showing a higher expression level of ZEB1 were more likely to develop into castration-resistant prostate cancer CRPC (P<0.05). 【Conclusion】 ZEB1 and N-Ca levels increase with increased tumor aggressiveness, while AR and E-Ca levels decrease. ZEB1, AR, E-Ca and N-Ca play important roles in prostate cancer progression. ZEB1 can not only affect prostate cancer through epithelial stromal transformation (EMT), but also through AR. ZEB1 may also be related to the development of CRPC.
