Objective To investigate the advantage and diagnosis rate of different image examination in breast diseases.Methods From January 2010 to February 2014,all image examination data of 389 breast disease pa-tients who received surgical operation were collected and analyzed retrospectively.All patients underwent color Doppler ultrasound examination.Breast X-ray photographic examination was performed in 325 patients,and MRI ex-amination in 188 patients,while 122 patients received MSCT examination.Results All surgical specimens were ex-amined and diagnosed pathologically.Of all the patients,176 patients were diagnosed with breast cancer(including 117 cases of infiltrating ductal carcinoma,48 cases of mucinous carcinoma,and 11 cases of carcinoma simplex),213 patients were confirmed as benign lesions (including 86 cases of adenomas,35 cases of intraductal papilloma,14 cases of lipoma,26 cases of atypical hyperplasia,34 cases of cystic hyperplasia,3 cases of fibroids,12 cases of adenomyosis, 2 cases of phyllodes tumor,and 1 cases with inflammation).The diagnosis rate with color Doppler ultrasound was 91.0%(354 /389),and the results showed suggestive of malignancy was 75.0%(132 /176 cases).The diagnosis rate with breast X-ray photographic examination was 89.5% (291 /325 cases),and suggestive of malignancy rate was 89.8%(158 /176).The diagnosis rate with MRI was 92.0%(173 /188),suggestive of malignancy was 93.8%(165 /176).The diagnosis rate with MSCT was 91.8% (112 /122),while the suggestive of malignancy was 92.0%(162 /176).Conclusions Both MRI and MSCT have a high diagnostic value than other image examination in discriminat-ing benign and malignant breast diseases.However,there is no difference in diagnosis rate in breast diseases whenever color Doppler ultrasound,breast X-ray photographic examination,MRI or MSCT was used.

After the concept of symptoms in traditional Chinese medicine was defined, the classification of symp-toms in traditional Chinese medicine and the characteristics of clinical diagnosis and treatment in traditional Chinese medicine were described .It was suggested that the symptoms in traditional Chinese medicine should be classified into 3 kinds, namely symptoms and signs according to the 4 diagnostic methods, symptoms and signs according to the diagnostic devices, symptoms and signs according to the physical constitutions of patients in order to lay a foun-dation for improving the classification in clinical term system of traditional Chinese medicine.

The source, super-antioxidant activity, biological safety and application in medicine, health food and animal feed industry of natural astaxanthin are reviewed in present paper. The industrialization prospect of astaxanthin in China is also proposed.

OBJECTIVE To introduce process management to procedure and standardization of infection management in common ward.METHODS Establishing and applying hospital infection control process,to use it in internal medicine and surgery wards(eight wards).Retrospective investigation was conducted to analyze the data.RESULTS Before and after using infection control process,there were significant differences between incidence of hospital infection in inpatients(P

This paper expatiates and analyzes the various problems in the course of using and maintaining the medical equipment in hospital.It also puts forward some substantive countermeasures to solve the problems such as training for operators,setting of management regulations,broadening the position and team construction of qualified personnel in medical engineering,etc.

0.05). Only the sVCAM-1 level of PILL type had significant difference with the healthy control group and KDDC type (P

AIM:To observe the effect of lidocaine to the activation of NF-?B and apoptosis in human neutrophils(PMN)in vitro.METHODS:Human PMN were divided into five groups:control group(0.9% sodium chloride);TNF-?(200 ng/L);TNF-?+lidocaine(1.0 mmol/L);TNF-?+lidocaine(2.0 mmol/L),and TNF-?+ lidocaine(4.0 mmol/L).The expression of NF-?B subunit p65 mRNA in the nuclear and I-?B mRNA in the cytosol extracts were analyzed by Western blotting,after co-incubation for 3 h and the content of p65 protein were observed by RT-PCR.PMN apoptosis was detected on flow cytometry after co-incubation 12 h and 24 h.RESULTS:The expression of NF-?B mRNA was significantly decreased and the expression of I-?B mRNA was markedly increased in lidocaine groups(P

Objective In this study, we explored the mechanism of anti-bone resorption of RGD-insulin using osteoclast-like cells (OLCs) from giant cell tumor of bone as an in vitro model. Methods The function of bone resorption was observed and the staining for tartrate-resistant acid phosphatase (TRAPase) was identified. The carbonic anhydrase Ⅱ (CAⅡ) gene expression, apoptosis and the adhesion of OLC that treated by RGD-insulin and echistatin were determined by in situ hybridization, TUNEL staining and adhesion test, respectively. Results OLCs were TRAP positive and had bone resorptive function. After OLCs were treated with 10 -5, 10 -6, 10 -7mol/L RGD-insulin and echistatin respectively, the numbers of TRAP-positive multinucleated cells were (179?3), (238?11), (351?10) per well that treated with echistatin and (229?20), (222?21), (265?17) per well that treat with RGD-insulin.The expression of CAⅡ mRNA decreased, the number of OLCs apoptosis increased in a dose-dependent manner (P

Objective To evaluate the dynamic MR imaging findings of peripheral cholangiocarcinoma (PCC) of the liver. Methods Seventeen patients with PCC underwent dynamic MRI during the early, middle, and delayed phase after contrast medium administration. Enhancement pattern of the tumor, the wedge-like enhancement area peripheral to the tumor, dilatation of the intrahepatic biliary ducts, vascular involvement, and extrahepatic tumor invasion were evaluated. Results Early peripheral enhancement with progressive and concentric filling by contrast medium was the most frequent enhancement pattern (9 patients). A wedge-like enhancement area was observed in 10 patients. Ductal dilatation was found in 11 patients. Vascular involvement and extrahepatic invasion were seen in 8 and 2 patients, respectively. Conclusion Enhancement pattern is relative to the character of pathology (quantity and distribution of cell and fibrosis). Early peripheral enhancement with progressive and concentric filling by contrast medium may be specific for PCC.

[Objective]To discuss the alterations of sesamoid position before and after opertation and its relation to the function of the metatarsophalangeal joints.[Methods]Eighty feet(39 hallux valgus feet,41 normal foot) were selected.The distance from sesamoids to the second metatarsal,the relative position of sesamoid bone to the first metatarsal bone,the function of the first metatarsophalangeal joints were determined and analyzed.[Results]The distance from sesamoid to the second metatarsal had no statistical significance in normal feet compared with the hallux valgus feet(P
