Objective To evaluate the correlation of pathology with color Doppler flow imaging and spectral flow Doppler in breast lumps for raising the diagnostic rate of breast lumps.Methods One hundred and sixteen cases with breast lumps were examined by color Doppler ultrasonography in comparison with their pathological results.Results ① In the group of malignant lumps,peak wave of contractive period often appeared ahead; contractive waves rose and descend quickly; beginning wave of diastolic period often appeared below the middle point of descending wave of contractive period; the latest wave of diastolic period often did not appear or appeared contrast wave .② In the group of benign lumps,peak wave of contractive period often appeared normal; contractive waves rose and descend slowly; beginning wave of diastolic period often appeared above the middle point of descending wave of contractive period ;the latest wave of diastolic period often appeared.Conclusions Spectral flow Doppler is an important index in differential diagnosis of breast lumps.

Objective To explore the clinical value of prenatal ultrasound on detecting fetal spleen.Methods 1850 normal cases and 34 cases of splenic abnormalities,including fetal anemia(31 cases) and intrauterine infection(3 cases),were included.All fetuses underwent standard ultrasound fetal biometry,routine fetal screening and splenic length and thickness measurement.The ultrasonic imaging and the size of fetal spleen in the two group of fetuses were compared and relevant statistical analysis was performed.Results ①In 1850 cases,the fetal spleen visual rate under prenatal ultrasound was 98.1％.②Linear regression analysis showed that there was a linear relationship between the thickness,spleen diameter and gestational age(GA) with simplified equation as follows:splenic length (mm)=GA,splenic thinckness (mm) =GA×0.5-4.③ In the 34 abnormal cases,the size of fetal spleen were significantly larger than those in normal fetuses.Conclusions It is important to detect fetal spleen by prenatal ultrasound which can provide valuable information for the diagnosis of fetal anemia and intrauterine infection.

Objective To investigate the current status and awareness of pharmaceutical services in hospitals in Guizhou province and to provide a reference for exploring and carrying out pharmaceutical service fees.Methods The questionnaire was designed by the"wjx.cn"website.Three kinds of questionnaires were designed for pharmacists,doctors,nurses,and patients as the research objects,with corresponding differences in some questions,and promoted on WeChat,Dingxiangyuan,and other network platforms.Results A total of 655 questionnaires were collected,and 639 valid questionnaires were recovered,with an effective recovery rate of 97.56%.324 pharmacists(50.70%),82 doctors and nurses(12.83%),233 patients(36.46%)were surveyed.The average approval score of these three groups of respondents on pharmaceutical service fees was 4.67,4.23,and 4.22,respectively(full score:5).Conclusions Overall,pharmacists'professional services have received support from medical staff and patients.However,patients'pharmaceutical service projects currently focus on dispensing services.The recognition of pharmacists'work and the public's awareness of pharmaceutical services can be improved by enhancing the professional ability of pharmacists,strengthening publicity and guidance,and exploring"Internet+pharmaceutical services",etc.,to promote the sustainable development of pharmaceutical services.
