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.

0.05). CONCLUSION: The effects of 10 mg?kg -1 m oxonidine on reduced blood pressure and heart rate in SHR is equal to the effect s of 1 mg?kg -1 clonidine after once large dose oral administration. T here is no significant difference between the moxonidine and clonidine of the sa me dose in reducing blood pressure after repeatedly small dose oral administrati on in SHR.

Objective To study the clinical therapeutic effects of early rehabilitation training combined with acupuncture on dysphagia after acute cerebral infarction.Methods One hundred patients with dysphagia caused by acute cerebral infarction were randomly divided into 4 groups:a comprehensive treatment group(25 cases,received rehabilitation training,acupuncture and routine medication),a routine drug group(25 cases,routine medication),a rehabilitation group(25 cases,received comprehensive rehabilitation training and routine mediciation)and an acu-puncture group(25 cases,received acupuncture therapy and routine medication).Dysphagia was evaluated with videofluoroscopic swallowing study(VFSS),and the incidence of pneumonia was observed before treatment and at the 14th day after daily treatment. Results After treatment,the VFSS scores of the 4 groups were significantly higher than before treatment,and VFSS scores in the comprehensive treatment group were significantly higher than those in the other groups.The effectiveness rate in the comprehensive treatment group was significantly higher than that in the other three groups.and the incidence of pneumonia was significantly lower.Conclusions Early rehabilitation com-bined with acupuncture can improve swallowing and reduce the incidence of aspiration pneumonia in acute stroke pa-tients.

Objective To determine the optimum dose of oxycodone for anesthesia when combined with propofol in the patients undergoing induced abortion.Methods Three hundred patients, aged 18-40 yr, weighing 40-70 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective induced abortion, were randomly divided into 6 groups (n =50 each) using a random number table: fentanyl group (group F) and different doses of oxycodone groups (Q1-5 groups).In group F, fentanyl 1 μg/kg was intravenously injected.In Q1-5 groups, oxycodone hydrochloride 20, 40, 60, 100 and 150 μg/kg were intravenously injected, respectively.Propofol 2.5 mg/kg was intravenously injected 1 min later in all the patients, and the operation was started when the eyelash reflex disappeared.The occurrence of hypotension, bradycardia, body movement and respiratory depression during operation, and nausea and vomiting within 4 h after operation were recorded.The uterine contraction pain was assessed with numerical rating scale (NRS) at 30 min, 1 h and 4 h after operation.Patient's satisfaction was evaluated at 1 and 4 h after operation.Results With the prolongation of time, NRS score was gradually increased, and the degree of patient's satisfaction was gradually decreased in group F (P＜0.05).With the prolongation of time,NRS score was gradually decreased, and the degree of patient's satisfaction was gradually increased in Q1-2 groups (P＜0.05).There was no significant difference in NRS score and degree of patient's satisfaction between Q3-5 groups (P＞0.05).Compared with group F, NRS score was significantly decreased, and the degree of patient's satisfaction was increased at 4 h after operation in Q1-5 groups (P＜0.05).Compared with Q1-2 groups, NRS score was significantly decreased at 30 min and 4 h after operation, and the degree of patient's satisfaction was increased at 4 h after operation in Q3-5 groups (P＜0.05).Among the Q1-5 groups,the incidence of respiratory depression, body movement, and nausea and vomiting was the lowest in group Q4 (P＜0.05).Conclusion When combined with propofol, the optimum dose of oxycodone for anesthesia is 100 μg/kg in the patients undergoing induced abortion.

OBJECTIVE: To analyze the features of orbital fracture and to discuss its forensic expertise points. METHODS: One hundred and thirty cases of simple orbital fracture from 2010 to 2012 collected from one public security bureau were retrospectively analyzed such as age, gender, tools, position and morphology of the fracture, periorbital and orbital compound injury and the follow-up results after 6 months. RESULTS: In the 130 cases, the wounded were mainly young men and hit by fist. The fracture of simple medial orbital wall accounted for up to 81.5% in all cases. In the periorbital and orbital compound injury, laceration and contusion of eyelid and ethmoidal cellules and maxillary sinus always occurred. After 6 months follow-up, there were 30 cases of comminuted fracture remained enophthalmos compared with the uninjured side. CONCLUSION It is inappropriate to judge the fracture of simple medial orbital wall as minor injury. We should judge the degree of simple orbital fracture after the injury is stable. Detailed ophthalmology inspection is necessary for forensic expertise of simple orbital fracture.

Objective To study emptying of gallbladder in children with functional dyspepsia(FD),and to investigate correlation of their helicobacter pylori(Hp) status and gallbladder emptying rate.Methods Sixty children with FD were studied,including 30 Hp-ne-(gative) and 30 Hp-positive children.Thirty Hp-positive children received triple eradication therapy 1 week.After 4 weeks,the Hp tests were taken again,27 children became Hp-negative,and the others were still positive eliminated from the study.The difference between the above groups in gallbladder volumes before breakfast and postprandial gallbladder emptying rate were compared.Results The gallbladder volumes before breakfast were bigger and the emptying rate of postprandial gallbladder of children with FD were lower than those of normal controls(P0.05).Conclusions Delayed emptying of gallbladder may cause FD in children.Hp infection isn′t associated with the gallbladder emptying rate.

ObjectiveTo study the expression and clinical significance of osteopontin in nasopharyngeal carcinoma tissues.MethodsOsteopontin expression was determined in nasopharyngeal carcinoma tissues in 44 cases and normal mucosa tissues in 25 cases by immunohistochemical staining.The relationship between osteopontin expression and pathological features of nasopharyngeal car(e)inoma was analyzed.ResultsThe positive expression rate of osteopontin in nasopharyngeal carcinoma tissues was significantly higher than that in normal tissues and the positive staining area was larger [77.27％(34/44) vs.8.00％(2/25),(60.24 ± 17.51 )％ vs.(1.32 ± 0.48)％ ](P＜0.05).The positive expression of osteopontin was correlated with clinical staging and lymph node metastasis(P ＜ 0.05),while had no relationship with pathological staging(P＞ 0.05).ConclusionsThere is a close correlation between expression of osteopontin and tumor cell invasion and metastasis.Over-expression of osteopontin may be one of the important factors contributing to the invasion and migration of nasopharyngeal carcinoma.
