Medical ultrasound technology is widely used for diagnosis and therapy in clinical practice.Ultrasound probes,which are directly contact with patients,pose a potential risk of pathogen transmission.This expert consen-sus was developed by a multidisciplinary team based on international guidelines,standards in China,and the results of a national survey,aiming to reduce the risk of healthcare-associated infection through standardizing reprocessing of medical ultrasound probes,and formulating consensus recommendations with the Delphi method.The consensus clarifies the reprocessing principles for three types of ultrasound probes of different infection risks:external-use ul-trasound probes,interventional percutaneous ultrasound probes,and internal-use ultrasound probes,puts forward systematic suggestions on the reprocessing standards and disinfection levels of ultrasound probe isolation covers and coupling agents,the reprocessing procedures and methods of ultrasound probes,as well as architectural layout and management of reprocessing,so as to provide a scientific prevention and control framework for ensuring ultrasound diagnosis and therapy safety.

Objective To review and investigate the malaria control history of Wuzhou City,Guangxi Zhuang Autonomous Region from 1950 to 2015,so as to provide the evidence for future malaria control and surveillance. Methods The data of ma?laria control in Wuzhou City from 1950 to 2015 were collected and analyzed. Results In 1950 decade,the malaria incidence in Wuzhou City was 1 435.55/100 000,higher than the average level in Guangxi,and the mortality of malaria was 0.95/100 000. The malaria incidence of local residents was reduced to 3.61/100 000 in 1979 and no local malaria case was found since. The im?ported malaria cases were found in Wuzhou City since 1980,and were more than local cases since 1981. In recent five years, 87.50%(7/8)of imported malaria cases were from south?east Asia. Conclusions Wuzhou City has reached the national criteri?on of malaria elimination,but the imported malaria is the recent threat. The surveillance and control work of malaria should be strengthened.

OBJECTIVE: To explore the clinical characteristic, the CT, MRI features, diagnosis and treatment of low grade myofibroblastic sarcoma in head and neck. METHOD: Six cases of low grade myofibroblastic sarcoma in head and neck were diagnosis and reviewed retrospectively. Routine preoperative CT and MRI examination were performed. RESULT: All cases were operated one case with radiotherapy before operation was given with a total dose of 60 Gy. The patients were follow-up for 6 months to 5 year and no recurrence was found. No complications occurred in 6 cases. CONCLUSION It has been confirmed in this research that LGMS is a low-grade malignangt tumor. It was difficult to make early diagnosis through frozen section. The final diagnosis depend on paraffin section and immunohistochemisty. Extended local excision with tumor-free margin is the treatment of choice.

OBJECTIVE: To investigate the expression of SOX2 in laryngeal carcinoma and analyze the relation of SOX2 and clinical factors. METHOD: We measured the expression of SOX2 protein in 45 laryngeal carcinoma fresh samples and 45 paracarcinoma tissues (cutting margin > 0.5 cm) with flow cytometer (Epics-XL II), 20 normal laryngeal mucosa samples were also studied as controls. RESULT: The quantitative and qualitative expression of SOX2 protein in laryngeal carcinoma tissues was obviously higher than those in paracarcinoma and in normal laryngeal mucosa tissues respectively (P < 0 05). There was no significant difference between the expression of paracarcinoma and normal laryngeal mucosa tissues. In laryngeal carcinoma, the expression of SOX2 protein wasn't significantly related to patients' clinical classification, tumor size, smoking history, patients' age and sex but related to metastasis, pathological grade and clinical stage. CONCLUSION The high expression of SOX2 may contribute to the carcinogenesis and development of laryngeal carcinoma. It is an important index of judging metastasis and staging and prognosis of laryngeal carcinoma to measure the expression of SOX2 protein.
