ObjectiveTo study the correlation between contrast-enhanced ultrasound (CEUS) features and Nottingham prognostic index (NPI) in patients with breast carcinoma. Methods The ultrasound features and microvascular imaging manifestation of 91 breast carcinomas confirmed by pathology were retrospectively analyzed.NPI was typically stratified into 3 major groups:NPI < 3.4 ( n =19 ), NPI:3.4-5.4 ( n =52 ) and NPI >5.4(n =21 ). Results With the increase of NPI, the rate of heterogeneous enhancement, perfusion defects, edge enhancement higher than center enhancement, and unclear border increased.The difference among the 3 groups had statistical significance (P < 0.05 ).There was no significant difference in enhancement order among the 3 groups ( P > 0.05 ).The lesions of the 3 groups were mainly “high enhancement” and there was no significant difference among the 3 groups ( P > 0.05 ).With the increase of NPI, the rate of early enhancement and late regression increased.The difference among the 3 groups had statistical significance ( P < 0.05 ).With the increase of NPI, the rate of enlarged and twisted vessels as well as peripheral vessel burr increased.There was significant difference among the 3 groups ( P < 0.05 ).ConclusionCEUS festures and microvescular architecture pattern of breast carcinoma are related to NPI, which is useful in predicating the prognosis of breast carcinoma.

Objective To investigate the clinical significance of contrast-enhanced transrectal ultrasound(CE-TRUS) in the perineal prostate biopsy. Methods A total of 116 patients was undergone prostate biopsy through the perineum under the direction of tansrectal ultrasound. Prostate biopsy standard was based on 2007 CUA revised guidelines for diagnosis and treatment of urological diseases.Color Doppler ultrasonography was used to check the prostate and to learn the prostate focal lesion,size, number and echo color Doppler flow characteristics. Of the 116 cases, 43 patients was undergone contrast-enhanced transrectal ultrasound. Results The biopsy results confirmed the diagnosis of prostate cancer was 64 cases, Benign prostatic hyperplasia was 52 cases. Of 43 cases who undergone contrast-enhanced transrectal ultrasound, Prostate cancer and Benign prostatic hyperplasia were 25 and 18 cases, respectively. CE-TRUS group and TRUS group showed no statistical difference between two groups. Analyzed the cases with PSA≤30 ng/ml, CE-TRUS group had a higher positive rate of biopsy (P=0.046). Conclusion TRUS guided transperineal biopsy of prostate might be an method for the diagnosis of prostate cancer with a higher accuracy rate. CE-TRUS can improve the biopsy positive rate of prostate cancer.

BACKGROUND:
LINC01234, a long noncoding RNA (lncRNA), is overexpressed in several cancers, including colorectal cancer (CRC). We investigated the role of LINC01234 in CRC development and confirmed its correlation with Krüppel-like factor 6 (KLF6), a tumor suppressor gene that is dysregulated in CRC.
METHODS:
We tested mRNA levels using quantitative reverse transcription PCR (qRT-PCR). Tissue samples from patients with CRC, inflammatory bowel disease (IBD), hyperplastic polyp, and adenoma were included. Correlations between clinicopathological parameters, overall survival (OS) rate, and LINC01234 were analyzed using Kruskal-Wallis H test. Additionally, cell proliferation, apoptosis, and tumor formation in nude mice were tested to investigate the mechanism of LINC01234. Western blotting was used to determine protein levels.
RESULTS:
LINC01234 expression was significantly upregulated in CRC tissues and CRC cell lines than in non-tumor tissues and normal epithelial cells, respectively. LINC01234 was associated with high tumor stage, larger tumor size, and metastasis. Patients with higher LINC01234 expression showed reduced OS. Cell proliferation was inhibited by LINC01234 knockdown, whereas apoptosis was enhanced. Mice injected with SW480 cells with LINC01234 knockdown displayed decreased tumor volume, weight, and Ki-67 levels compared with those injected with control cells. KLF6 was negatively regulated by LINC01234. Overexpression of KLF6 showed effects similar to those observed following LINC01234 knockdown on cell proliferation and apoptosis.
CONCLUSIONS
LINC01234 could be a prognostic biomarker in CRC patients. Upregulation of LINC01234 in CRC promotes tumor development through negative regulation of KLF6.

OBJECTIVEIn order to minimize lead pollution and to protect the identified individuals with high blood lead level from lead contamination, an epidemiological study was carried on children living around the village and township-owned lead industries in Tianying town.
METHODSEnvironmental monitoring: lead levels in air, soil, drinking water and crops were measured. Biological monitoring: 959 children aged 5 - 12 years were selected from villages where the lead smelters located near the residential areas and the battery disassembling was done in some families. The control children (207 pupils) were from other villages without lead exposure. Blood lead, ZnPP and teeth lead were determined. Height, weight and head circle of children and IQ scores were measured.
RESULTSThe environment was seriously polluted. The average lead concentrations in air and soils were 8.5 times and 10 times of the MACs (national health standard) respectively. Eighty-five per cent the air samples with lead concentrations higher than the national health standard. Local crops and wheat at farmers' home were also contaminated by lead dust, with. Lead content being 24 times higher than the standard. The mean blood lead and ZnPP levels of children lived in the polluted areas were 496 microgram/L and 9.41 microgram/g Hb respectively. The lead exposure caused adverse effects on children's IQ and physical development.
CONCLUSIONIt is necessary to remove and reduce currently active sources of lead pollution in the community and to increase public awareness of potential health effects of lead exposure.
