Objective This study is focused on ultrasound multimodality examination,which refers to the combined use of three ultrasound examination modalities,ultrasound(US),acoustic radiation force impulse(ARFI)imaging,and contrast-enhanced ultrasound(CEUS).The purpose of this study is to analyze the value of applying ultrasound multimodality examination in the differential diagnosis of benign and malignant breast non-mass-like lesions(NMLs).Methods Cases of breast NMLs were analyzed retrospectively,and the nature of all the lesions was verified by pathological examination.Based on the gray-scale ultrasound image characteristics,the cases were classified into types Ⅰto Ⅴ,and type Ⅰ and type Ⅱ were further classified into 4 subtypes,Ⅰa,Ⅰ b,Ⅱ a,and Ⅱ b,according to whether there was also calcification,and the proportion of malignant cases in each subtype was statistically analyzed.Logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS for the diagnosis of malignant cases were established,ROC curves were drawn,the area under the curve(AUC)was calculated,and comparisons were made accordingly.The detection rate of malignant NMLs without calcification(atypical malignant NMLs)by the combination examination of US,ARFI,and CEUS was analyzed.Results A total of 407 cases were included in the study.All subjects were female,aged 22 to 81 years,with the average age being(47.0±1 1.0)years.There were 220 benign cases and 187 malignant cases.Ranked from the highest to the lowest,the malignancy proportion of the different types wasⅠb＞Ⅱb＞Ⅲ＞V＞Ⅰa＞Ⅱa＞Ⅳ.The malignant proportion of the low echo area with calcification was significantly higher than that of the lesions without calcification.The AUC(95％confidence interval[CI])for diagnosing malignant cases with the logistic regression models of US,US+ARFI,US+CEUS,and US+ARFI+CEUS were 0.895(0.862-0.927),0.908(0.878-0.937),0.921(0.893-0.948),and 0.927(0.902-0.952),respectively.Comparison of the AUC of the 4 regression models showed significant differences(P＜0.001).The detection rate of US for NMLs without calcification was 80.7％.When US was used in combination with ARFI and CEUS,86.4％of the malignant NMLs lesions without calcification could be detected if the lesion CEUS score was 4 or 5 points or if shear-wave velocity(SWV)≥4.28 m/s.Conclusion Breast NMLs with calcification show high risks of malignancy,and a pathological examination is always recommended for a conclusive diagnosis.Ultrasound multimodality examination can improve the diagnostic accuracy of breast NML without calcification.

When the body is attacked by trauma and infection,the serum C-reactive protein( CRP) con-centration which is produced by the liver will increase.CRP participates in the body′s humoral immunity through regulating the phagocytic cells to clear the pathogenic bacteria and necrotic tissue.The occurrence and develop-ment of malignant tumor is associated with complex inflammatory response pathway.Serum CRP concentration will change with the progress and remission of tumor.CRP is associated with differentiation of benign and malignant, the early diagnosis,the pathological stage,the lymph node metastasis,the organizational characteristics,the prog-nosis,and the treatment of malignant tumor.It is expected to be a clinical screening indicator of malignant tumor.

Objective To set up an objective criterion for BI-RADS assessment.Methods The breast sonograms of 1 938 female cases were retrospectively studied which had been confirmed by pathology from January to September 2011 and 2012 January.1 660 cases during 2011 were model cases,and the importance of each single feature in distinguishing between benign and malignant was obtained with Chi square and OR value.A detailed criterion of BI-RADS assessment category was set up based on US-BI-RADS.Results Eighteen of 24 lexicons were statistically significant distinguished between benign and malignant breast masses(P ＜ 0.05).The lexicons were divided into major suspicious signs,middle ones and minor ones assigned 3 points,2 points and 1 point,and a scoring model was established as follows:Score =3 * (X1 + X2 + … + X6) + 2 * (X7 + X8 + … + X12) + (X9 + X10 + … + X18).Based on BI-RADS,the positive predictive value of model cases was 1.5％,6.9％,22.1％,62.5％,96.1％ followed by category 3,4A,4B,4C and 5,and it was 1.4％,3.4％,21.1％,69.4％,92.7％ in test cases.Conclusions The scoring model could be useful for BI-RADS final assessment more objectively,and could make it more convenient to predict the risk of breast cancer.

The sonographic features of male breast lesions, which underwent ultrasound examination in our hospital for the past 10 years, were retrospectively analyzed. Sonographic features of these lesions were standardized as BI RADS image lexicon. The differences in ultrasonic malignant signs were assessed between the benign and the malig nant diseases. Between the two groups, incomplete boundary was statistically different. The specificity was above 95% within the two groups in terms of speculated margin, echogenic halo, calcification, axillary lymphadenopathy, thickening of skin and eccentric of mass to the nipple. High-frequency sonographic examination has a high level of differential diagnosis for male breast lesions.

To improve spinosyn-producing strain and enhance spinosyns yield, we studied the effects of glycin concentration and the operational time, temperature and lysozyme concentration on protoplast preparation of Saccharopolyspora spinosa SP06081. We also studied different regeneration media and osmotic stabilizing agents. In addition, we compared the change of morphology and spinosyns yield of the regenerated strains. The results showed that the Saccharopolyspora spinosa SP06081 protoplast yield was the highest under these conditions: the collected mycelium from SP06081 grown in Tryptic Soy Broth (TSB) medium with 0.2% glycin for 48 h was treated by 0.1 mg/mL lysozyme at 28 degrees C for 20 min, then plated on the R2YE medium with sucrose as osmotic stabilizer, the number of regeneration protoplast was up to 10(8)/mL. The protoplast-regenerated strains exhibited changes in morphology and antibiotic production, 29.3% protoplast-regenerated strains was characterized by loose mycelium and abundant broken branches as did their parent. Among them, 58.2% strains presented the trend to positive variation in spinosad yield, with the highest spinosad yield of up to 582.0 mg/L, 85.6% higher than that of their parent. There is significant correlation between the morphological differentiation and antibiotic yield of the protoplast-regenerated strains from spinosyn-producing strain.

Objective: To determine the predictive value of excision repair cross complement 1 (ERCC1) expression in non-small cell lung cancer (NSCLC) and the sensitivity of NSCLC to non-cisplatin based chemo-therapy and cisplatin based chemotherapy. Methods: The expression of ERCC1 was examined by immunohis-tochemical technique in 130 patients with advanced NSCLC seen in our hospital between February 1st 2006 and October 30th 2007. These 130 patients were divied into three groups. Patients in group A (n=68) had neg-ative ERCC1 expression and received cisplatin based chemotherapy. Patients in group B (n=31) had positive expression of ERCC1 and received non-cisplatin based chemotherapy. Patients in group C (n=31) had posi-tive expression of ERCC1 and received cisplatin based chemotherapy. Results: The expression rate of ER-CC1 was 62 of 130 (47.8%). The rate of ERCC1 in pulmonary adenocarcinoma was higher than that in squa-mous carcinoma. The response rates of chemotherapy in group A, B, and C group were 58.8 %, 51.6%, and 41.5%, respecitvely. There was no significant difference in the response rate between group A and group B (X~2=0.451, P=0.502). There was a significant difference in the response rate between group A and group C (X~2= 6.011, P=0.014). The response rate in group B was higher than that in group C (X~2=2.384, P=1.123). The average survival time in group A, group B, and group C were 12.0 months, 11.0 months, and 7.8 months, respecit-vely. There was no significant difference in patient survival between group A and group B (X~2=3.809, P=0.051). There was significant difference in patient survival between group A and group C (X~2=46.368, P=0.000). Con-clusion: ERCC1 may be an important indicator of the sensitivity of advanced NSCLC to cisplatin or non-cisplat-in based chemotherapy.
