OBJECTIVETo investigate the accuracy, consistency and related affecting factors in pathological results of breast lesions diagnosed by ultrasound-guided core needle biopsy (CNB) and conventional excision histopathology.

METHODSThe clinical data of 177 consecutive cases of breast lesions examined by ultrasound-guided CNB and subsequently excised were reviewed from Jan. 2003 to Nov. 2009. The agreement of pathological diagnosis between the CNB and subsequent excision pathology was analyzed.

RESULTSThere were 136 cancers in the final diagnosis after surgical excision among 386 breast lesions and 129 of them were diagnosed by CNB. The sensitivity (true positive) of CNB was 94.9%, false negative rate was 5.1%, specificity (true negative) was 100%, false positive rate 0, Youden's index was 0.949, and positive predictive value and negative predictive value were 100% and 85.4%, respectively. Condensation rate was 96.0% and Kappa value was 0.895.

CONCLUSIONUltrasound-guided CNB with histopathological assessment is accurate in diagnosis of breast lesions and has a great consistency with conventional excision pathology. It is a reliable method for the diagnosis of breast lesions to avoid an over-reliance on excision pathological examination.

OBJECTIVETo evaluate the cost-effectiveness of two-stage and three-stage hearing screenings for newborns.

METHODSHearing screening was performed for the normal newborns born in 7 hospitals in Beijing from October 2010 to December 2012 by using two stage and three stage strategies as well as hearing diagnostic test, and the cost effectiveness evaluation of two strategies was conducted. The data about the cost of screening and diagnostic test were from the hospitals. The data about car fare and charge for loss of working time of parents were collected through questionnaire survey. The sensitivity was analyzed according to the compliance rate.

RESULTSA total of 62,695 newborns received initial hearing screening, 5,809 newborns failed, the positive rate was 9.30%. A total of 4,933 newborns received rescreening, 972 newborns failed, the positive rate was 19.70%. Among the newborns failed in rescreening, 412 were provided with hearing diagnostic test and 360 received diagnostic test. The diagnostic test indicated that the hearing of 217 newborns were abnormal (60.28%). A total of 276 newborns received the third screening, 163 newborns failed, in which 125 received diagnostic test and 112 had abnormal hearing (45 had moderate and above hearing impairment), the abnormal rate was 89.60%. The average cost for three-stage screening (37,242 yuan RMB per case) was higher than that for two-stage screening (19,985 yuan RMB per case). With the increase of compliance, the cost-effectiveness of three-stage screening increased.

CONCLUSIONThe cost-effectiveness of three-stage screening was influenced by screening compliance. It is recommended that three-stage screening strategy might be taken in area where the screening compliance rate is >90%.

OBJECTIVE: To investigate the effect of zoledronate (ZOL) on osteoclast differentiation and bone resorption under high glucose, and the regulation mechanism of p38 mitogen activated kinase (p38 MAPK) signaling pathway in this process. METHODS: RAW264.7 cells were divided into four groups: low group, high group, low+ZOL group and high+ZOL group after induced into osteoclasts. Cell proliferation activity was determined by MTT assay. The migration of RAW264.7 cells were examined Optical microscopy. Immunofluorescence microscopy was used to observe the cytoskeleton and sealing zones of osteoclasts. After adding group 5: high + ZOL + SB203580 group, trap staining was used to identify the number of positive osteoclasts in each group. The number and area of resorption lacunae were observed by SEM. The mRNA and protein expression of osteoclast related factors were detected by real-time PCR and Western blotting. RESULTS: The cells in the 5 groups showed similar proliferative activity. High glucose promoted the migration of RAW264.7 cells ( CONCLUSIONS High glucose inhibits osteoclast differentiation and bone resorption. ZOL inhibits osteoclast differentiation and bone resorption in high-glucose conditions by regulating p38 MAPK pathway, which can be a new pathway for ZOL to regulate diabetic osteoporosis.
