Purpose:To study the value of high frequency color doppler ultrasound diagnosis for breast intraductal papilloma.Methods:50 patients with breast intraductal papilloma,all confirmed by surgical and pathology,and examined by ultrasound before surgery,all had symptoms of excreting blood or liquid from nipple or palpable mass. The probe were placed on the surface of the breast to scan radially from nipple,after finding the enlarged duct,try to detect the neoplasm in it carefully. The two dimensional images were observed and the color Doppler flow codes were detected.Results:The detection rate and the diagnostic accuracy rate of breast intraductal papilloma by ultrasound are 62.0% and 38.0% respectively,ultrasonography is better than mammography and near infrared light scanning.The images were divided into four types:one type of no unusual finding(7 cases),one type of finding both the enlarged duct and the tumor(19 cases),one type of finding the enlarged duct only(12 cases),one type of finding the tumor only(12 cases),the images of the type of finding both the enlarged duct and the tumor are typical. The detection rate of flow by color doppler ultrasound is low(5/50).Conclusions:The high frequency color doppler ultrasound is valuable in diagnosis of breast intraductal papilloma,and the special symptom ,the accurate detection method and the typical images are the key of ultrasound diagnosis.

Objective To investigate the value of transvaginal contrast-enhanced ultrasonography (CEUS)in the diagnosis of adnexal masses.Methods Thirty patients with adnexal mass were examined by conventional 2D imaging and contrast tuned imaging(CnTI)technology.The results were compared with pathological results and the CEUS features wet concluded.Results There were 21 cases of benign adnexal masses and 9 cases of ovarian malignancies among 30 patients.The CnTI technology can distinguish between solid and cystic parts in masses.CEUS showed that malignant tumor had the high microvessel density and these vessels were irregular in shape.Partial malignant masses had the characteristic in-out phases in CnTI imagine.Conclusions Transvaginal CEUS is benefit to improve the accuracy of diagnosis of pelvic adnexal masses.

Objective To find out the situation of laboratory testing capacity of fluoride in drinking water in Guizhou Province.Method Assessment of fluoride detection capabilities in nine cities (states) and 31 countylevel laboratories of the province in 2010 was carried out,the test results of individual indicators were evaluated using a single Z-score method,and the determination was based on the fluoride ion selective electrode method of Drinking Water Saritary Standard Test Method (GB/T 5750.5-2006) or fluorine reagent spectrophotometry.Results The feedback rate of fluoride measurement results was 100％,the satisfactory rate of laboratory results was 82.5％,the suspicious rate of results was 7.5％(33/40),and the unsatisfied rate was 10.0％(3/40).Conclusion The fluoride detection capability of most laboratories that participated in the proficiency test has met the requirements,and 10 percent of the laboratory's capacity needs to be improved.

Tort Liability Law set tougher requirements on the validity and authenticity of medical records,featuring explicit protection of patient rights of informed consent.Based on the changes in the law since its enforcement,the authors studied existing deficiencies of electronic medical records and came up with the following suggestions.Establish sound legal accreditation system for electronic medical records; perfect related laws and regulations to ensure standard application of the electronic medical records; and work out regulations to make medical staff aware of their legal responsibilities when applying electronic medical records.These recommendations will enable electronic medical records better fit the current legal environment onto the track of healthier development.

Objective To observe the effect of Sijunzi Decoction(SD) and Huangqi Sijunzi Decoction(HSD) on mitochondrial succinate dehydrogenase,cytochrome oxidase activity of liver in rats with spleen asthenia,thus to reveal the pathogenesis mechanism of spleen asthenia from energy metabolism,and to clarify the therapeutic mechanism of spleen-invigorating and Qi-tonifying herbs.Methods Forty SD rats were randomly divided into 4 groups:normal control group,spleen-asthenia model group,SD(10.5 g/kg) group and HSD(18 g/kg) group,10 rats in each group.Except that the normal control group,the rats in the other groups were fed with half-full diet once every other day and with gastic gavage of Xiaochengqi Decoction 60 g/kg every day to establish animal model of spleen asthenia.After 15 days,the model rats were administered the corresponding drugs according to the experimental design for 4 continuous weeks.The changes of mitochondrial succinate dehydrogenase,cytochrome oxidase activity of liver were measured,and the general status of the rats were observed.Results Compared with the normal control group,the level of mitochondrial succinate dehydrogenase and cytochrome oxidase activity in liver of spleen asthenia group were decreased obviously(P

To evaluate the status of diabetes-related knowledge and training requirement among general physicians,a questionnaire survey was conducted in 676 general physicians from 32 primary medical institutions and 5 secondary hospitals of Shanghai Pudong New Area.48.2% (261/541) of the surveyees had bachelor degree and most of them worked in secondary hospitals or primary medical institutions in affluent areas.The awareness rate of diabetic knowledge among the surveyeos was 51.6%,and there were significant differences in the awareness rate of diabetes-related knowledge between different levels of hospitals and physicians with different academic background.Only 26.6% of physicians received diabetes-related continuing education or training,there was a popular request for professional training from the surveyed physicians.

Objective To investigate the role of transoralsonography guiding fine?needle aspiration biopsy in the diagnosis of retropharyngeal or parapharyngeal masses identified on the CT, MRI or PET?CT images of treated patients with malignant carcinoma. Methods From 2002 to 2013,this study recruited fifty?five patients with a history of cancer, of which 50 were treated with radiation treatment, including 46 nasopharyngeal carcinoma, 3 esophagus squamous cell carcinoma and1 lung apex carcinoma. There were 4 patients with a history of 1 thyroid papillary carcinoma, 1 buccal mucosa squamous cell carcinoma,1 glottis squamous cell carcinoma and 1 sigmoid colon adenocarcinoma treated with surgery. The rest one patient with nasal olfactory neuroblastoma was treated by postoperative radiation. The enlarged retropharyngeal lymph nodes in 44 cases and parapharyngeal masses in 10 cases were identified on CT or MRI imges. The enlarged retropharyngeal lymph node in the rest case was identified on PET?CT. With transoral ultrasound examination, all lesions were with hypo?intensity echo. Cystic areas were noted on occasion. Biopsy was performed in all cases. Results After cytology examination, carcinoma cells were detected in 37 retropharyngeal lymph nodes, with a detection rate of 82% (37/ 45). In the 10 parapharyngeal masses, carcinoma cells were detected in 3 lesions, with a detection rate of 30%. Conclusions Transor alsonography guiding fine?needle aspiration biopsy can be useful in the cytopathology diagnosis of retropharyngeal or parapharyngeal masses identified on the CT, MRI or PET?CT images of treated patients with malignant carcinoma,which facilitates, early diagnosis and treatment for patients.

OBJECTIVE: To assess the effect of CPAP therapy on sleep quality and quality of life in patients with moderate or severe OSAHS. METHOD: Seventy-two patients diagnosed as OSAHS by polysomnography (PSG) were assigned to receive CPAP therapy for 3 months. At baseline and three months after treatment patients underwent polysomnography (PSG). Analyze the results of PSG, sleep quality, excessive daytime sleepiness, quality of life and the general well-being. RESULT: The lowest average oxygen saturation and the average blood oxygen saturation improved significantly after CPAP therapy, and the longest sleep apnea time and AHI decreased obviously (P < 0.01). Except body pain, the other seven dimensions of SF-36 improved obviously (P < 0.01); ESS, PSQI and GWB also improved (P < 0.05). CONCLUSION For patients with moderate or severe OSAHS, CPAP therapy can obviously improve the sleep quality, excessive daytime sleepiness, improve patients' life quality and the general well-being.
