Objective:To analyze the status of doctor -patient trust and its influencing factors based on the per-spective of the villagers .Methods:Using purposive sampling method , the selection of the H area as the research site in Beijing , for in the 14 township 80 administrative villages of trust information in the form of questionnaire sur-vey .Results:The 350 villagers were surveyed 301 villagers of village clinics held a positive attitude to the doctor -patient relationship , accounted for 86 .00%;There are 44 villagers of village clinics the middle ground the doctor-patient relationship , accounted for 12 .57%;Only five of the villagers of village clinics have held a denial atti-tude to the doctor-patient relationship , accounts for 3.43%of the proportion of the total .Based on blood kinship relationship between the villagers of village clinics and rural doctors more trust , but the technical level and service ability are the main factors affecting doctor -patient trust .Conclusion:Rural doctors and villagers in the same vil-lage , has a common living environment , interpersonal relationship , morality , interpersonal trust between each other is higher .In clinical activities , formed by the interpersonal relationship with the clinical common existing doctor -patient trust , is essentially interpersonal trust mask a lack of technology .Transformation in the society , how to im-prove the service ability of the village clinic , realize the village clinic real doctor -patient trust is the important connotation of health reform .

OBJECTIVE：To establish a method for the content determination of potential genotoxic impurity maleic hydrazide in azintamide raw material. METHODS ：HPLC-FLD method was adopted. The determination was performed on Thermo Syncronis C18 column with mobile phase consisted of 0.2 mol/L acetic acid-methanol （gradient elution ）. The column temperature was set at 30 ℃，the excitation wavelength was 315 nm and emission wavelength was 389 nm. The flow rate was 1 mL/min，and the sample size was 20 μL. RESULTS：The blank solvent and azintamide did not interfere with the determination of maleic hydrazide. The linear range of maleic hydrazide was 19.5-300 ng/mL（r＝0.999 9）. The limit of detection was 4.5 ng/mL and the limit of quantification was 19.5 ng/mL. The recovery ranged from 98.79％ to 103.76％（RSDs were lower than 3.00％，n＝9）. RSDs of precision and stability （24 h）tests were no more than 5.63％，and those of durability tests were less than 2.00％（n＝6）. Maleic hydrazide was not detected in 3 batches of azinamide raw material. CONCLUSIONS ：The method is specific ，sensitive and accurate. It can be used for the trace determination of maleic hydrazide in azintamide or other matrix.
