Chinese Journal of Medical Ultrasound (Electronic Edition) 2014;(6):447-451
Objective To evaluate the clinical value of the coronal plane of three-dimensional ultrasonography in the diagnosis of breast cancer. Methods Ninety-seven patients with 106 solid breast lesions were analyzed retrospectively. Two-dimensional images were evaluated with breast imaging reporting and data system for ultrasonography (BI-RADS-US) classification and were compared with pathological results. The value of two-dimensional ultrasound in the differentiation of benign and malignant lesions of breast lesions was evaluated. The ultrasonographic features on three-dimensional coronary plane of breast benign or malignant masses were analyzed by multiple stepwise binary logistic regression analysis. Receiver operating characteristic (ROC) curve was drawn and the areas under curves were calculated to evaluate the ability of regression model in diagnosis of benign and malignant breast lesions. Results The pathological results revealed that 106 lesions were consisted of 71 breast cancers and 35 benign neoplasms. The diagnostic accuracy, sensitivity and speciifcity were 85.8%, 84.5%and 88.6%respectively. Two ultrasonic features which were finally applied into the Logistic regression model were angulation or spiculation and′sun-like symptom′. The area under the ROC curve was 0.899, the standard error was 0.033, and the 95%conifdence interval was between 0.834 and 0.965. The logistic regression model could be useful for classiifcation of benign and malignant breast masses. The diagnostic accuracy was 88.7%(94/106), sensitivity was 90.1%(64/71), speciifcity was 85.7%(30/35), positive predictive value was 92.8%(64/69) and negative predictive value was 81.1%(30/37) respectively. Conclusions The coronal plane of breast three-dimensional, especially angulation or spiculation and′sun-like symptom′have an important value in the differential diagnosis of benign and malignant breast lesions. For complicated lesions, three-dimensional ultrasound coronal plane is helpful to improve the doctor′s diagnosis conifdence.

Chinese Journal of Nosocomiology 2006;0(07):-
OBJECTIVE To study the homology of resistant Gram-negative bacteria isolating from the hospitalized patients,hospital environment and hands of medical staffs in intensive care unit(ICU).METHODS To collect and identify 58 clinical resistant Gram-negative bacteria isolates and environment isolates from intensive care units,the same type of Gram-negative bacilli were studied on the homology using plasmid profile,restriction endonuclease profile and enterobacter repetitive intergenic consensus PCR(ERIC-PCR).RESULTS The homology existed between the resistant bacteria of clinical isolates and environment specimens.CONCLUSIONS We found that the multidrug-resistant Gram-negative bacteria derive from a common origin and cause an outbreak in ICU.So medical staff must emphasize the concept of hand hygiene and reinforce the measure of cleaning and sterilization,in order to control nosocomial infection.

Objective To study the effect of cirrhosic liver on dynamic vascular curves analysis f(t)of hepatocellular carcinomas(HCCs) at contrast-enhanced ultrasound by exploring the difference between perfusion parameters of HCCs in cirrhotic liver and that in noncirrhotic liver. Methods One hundred and fifteen HCCs were analyzed off-line with dynamic vascular curve f(t) of Sonoliver. The HCCs were divided into 2 groups based on their background liver as cirrhotic liver group ( n = 86) and noncirrhotic liver group ( n =29). Such parameters as maximum of intensity(IMAX) ,rise time (RT,from 10% to 90% of IMAX),time to peak(TTP) ,mean trasit time(mTT) ,rise slope(RS) and washout time(WT) of the two groups were analyzed by statistics. Results There was no significant difference in the f(t) parameters of HCCs between cirrhotic liver group and noncirrhotic group(P >0. 05) [IMAX:(124. 25 ± 5. 56)% vs (113. 65 ± 5. 58)% ; RT: (12. 98 ± 0. 48)s vs (13. 68 ± 0. 92)s;TTP:(13. 70 ± 0. 52)s vs (14. 39 ± 0. 9)s;mTTi(138. 61 ± 9. 20)s vs (149. 49 ± 21. 70)s;RS:10. 11 ± 0. 60 vs 8. 89 ± 0. 77, WT: (34.17 ± 2. 91 )s vs (28. 36 ± 3. 25)s]. There was also no significant statistical difference in all above parameters in reference regions for the two group (P > 0. 05). Conclusions The f(t) parameters in HCCs can evaluate blood perfusion of the tumors, and cirrhotic liver does not affect the perfusion parameters of HCCs.

Objective To investigate the clinical characteristics,surgical indications and methods of children sylvian cistern arachnoid cysts complicated with subdural hematoma.Methods Fifty childhood cases of sylvian cistern arachnoid cyst complicated with subdural hematoma were retrospectively analyzed,who were all surgically treated in the First Affiliated Hospital of China Medical University from July 2005 to August 2015.Among them,20 childhood cases were subacute subdural hematoma,30 childhood cases were chronic subdural hematoma.All patients underwent microscopic cyst excision,cystocistern fenestration plus hematoma removal surgery.During the surgery,firstly we resected the cyst wall tissue as far as possible,and then we communicated the cyst with subarachnoid space and cisterns,which could make the cerebrospinal fluid flowed unobstructedly.Results The course of every operation was smooth,and there was no severe complication postoperatively.Original symptoms and imaging manifestation resolved or improved in all patients.During a mean follow-up period of 5.7 years,there were no recurrent cases.Conclusion Children sylvian cistern arachnoid cyst can induce subdural hematoma.In this situation,microscopic cyst excision,cystocistern fenestration plus hematoma removal surgery is safe and effective.
