Objective To observe the expression of triggering receptor-1 on myeloid cells (TREM-1) of mice with acute lung injury (ALI) in oder to find out its regularity and significance in inflammatory response of or-ganisms. Method Thirty BALB/C mice were randomly(random number) divided into normal control group (n =6) and ALl group (n = 24). The models of ALI were made with intraperitonal injection of lipopolysaccharide (LPS) in dose of 10 mg/kg. Specimens from peripheral blood and lung tissue were collected 6 h, 12 h, 24 h and 48 h after LPS injected. The fluorescent real-time quantitative reverse transcriptiun-polymerase chain (RT-PCR) was used to detect TREM-1 mRNA, and ELISA was employed for detection of TREM-1 protein and TNF-α protein, and HE staining was made doe the pathological Smith lung score under light microscope. Analysis of variance was used for comparison of TREM-1 mRNA, TNF-α and Smith lung injury score between two groups. Spearman corre-lation analysis was made to find out the relationship among these three variables. Results The expressions of TREM-1 mRNA in lung tissue of ALI mice 6 h, 12 h, 24 h, and 48 hours after injection of LPS were 6.61±0.08,34.71±0.83, 61.85±14.05 and 56.46±8.89, respectively which were higher than that in control group (1.00±0.00, P = 0.017, 0.009, 0.002 and 0.003, respectively). The expressions of TREM-1 mRNA in blood were 14.01±3.24, 47.07±0.98, 8.18±0.43 and 8.06±0.05, respectively which were higher than that in normal control group (1.00±0.00, P = 0.010, 0.004, 0.011 and 0.011, respectively). The expression of TREM-1 rnRNA in tissue began to increase 6 hours after modeling and reached its peak 24 hours later, and expres-sion of TREM-1 mRNA in blood reached its peak after 12 hours. The levels of TREM-1 protein in lung tissue of ALl mice 6 h,12 h,24 h and 48 hours after LPS injected were 997.8±114.62, 1579.70±45.92, 1123.9±108.2 and 429.8±89.96 pg/mL, respectively which were higher than that of mice in control group (279.22±4.62 pg/mL, P = 0.024, 0.007, 0.011 and 0.04, respectively). The level of TREM- 1 protein reached the peak 12 hours after LPS injected, but it had no significant correlation with the expression of TREM-1 mRNA (P =0.14). The levels of TNF-α protein in lung tissue of ALI mice 6 h, 12 h, 24 h and 48 hours after LPS injection were 313.16±39.50, 491.91±96.65, 388.48±29.84 and 282.5±52.76 pg/mL, respectively which were sig-nificantly higher than that of mice in control group (256.6±28.31 pg,/mL, P = 0.037, 0.019, 0.032 and 0.043, respectively). The TNF-α concentration was positively correlated with TREM-1 levels in lung tissue and with Smith pathological score (r = 0.795, P = 0.001: r = 0.499, P = 0.034), but not with the expression of TREM-1 mRNA (P = 0.176). Conclusions The expression of TREM-1 mRNA in lung tissue of mice with ALI is elevated, and the expression of TREM-1 mRNA is related to the level of TNF-α and the severity of the ALI in in-flammatory responses in lung. The expressions of TREM- 1 gene are not consistent with the levels of TREM- 1 pro-tein, suggesting another new functional proteins involved in immune regulation.

BACKGROUND:Myeloid cell (TREM-1) is an important mediator of the signal transduction pathway in inflammatory response. In this study, a mouse model of acute lung injury (ALI) by intraperitoneal injection of lipopolysaccharide (LPS) was established to observe the expression pattern of TREM-1 in lung tissue and the role of TREM-1 in pulmonary inflammatory response to ALI. METHODS:Thirty BALB/C mice were randomly divided into a normal control group (n=6) and an ALI group (n=24). The model of ALI was made by intraperitonal injection of LPS in dose of 10 mg/kg. Specimens from peripheral blood and lung tissue were collected 6, 12, 24 and 48 hours after LPS injection. RT-PCR was used to detect TREM-1 mRNA, and ELISA was employed for detection of TREM-1 protein and TNF-a protein, and HE staining was performed for the pathological Smith lung scoring under a light microscope. RESULTS:The expressions of TREM-1 mRNA in lung tissue and blood of the ALI group 6, 12, 24, and 48 hours after injection of LPS were higher than those in the control group. The levels of TREM-1 protein and the levels of TNF-a protein in lung tissue of the ALI group 6, 12, 24, and 48 hours after LPS injection were higher than those of the control group; the level of TREM-1 protein peaked 12 hours after LPS injection, but it was not significantly correlated with the expression of TREM-1 mRNA (P=0.14); the TNF-a concentration was positively correlated with TREM-1 levels in lung tissue and with Smith pathological score (r=0.795, P=0.001:r=0.499, P=0.034), but not with the expression of TREM-1 mRNA (P=0.176). CONCLUSIONS:The expression of TREM-1 mRNA in lung tissue of mice with ALI is elevated, and the expression of TREM-1 mRNA is related to the level of TNF-a and the severity of inflammatory response to ALI. The expressions of the TREM-1 gene are not consistent with the levels of TREM-1 protein, suggesting a new functional protein involved in immune regulation.

Objective To retrospectively evaluate the mammographic features of breast ductal carcinoma in situ (DCIS)and DCIS with small invasive foci,and to analyze the correlation between the mammographic findings and the prognostic biologic factors.Methods The mammographic examination was performed in 95 consecutive women with breast DCIS(n = 50)and DCIS with invasive foci(n = 45 ).The prognostic biologic factors including progesterone receptor(PR),C-erbB-2,and p53 were evaluated in 62 of 95 cases.Categorical data were expressed as percentages and analyzed by using the X~2 test,and furthermore the odds ratio was measured.Results(1)Only one abnormality was seen on mammography in 62 patients. Combined two abnormalities on mammography were seen in 26 patients.Mammograms were normal in 7 patients.(2)Calcifications with or without other abnormality were noted in 62 cases.Of them,73% (n =45)had higher probability of malignancy calcifications and the others were intermediate concern calcifications.Clustered calcifications(36 lesions)was the most common distribution,which usually accompanied by another abnormality.And then were segmental(18 lesions)distributed pattern.As far as the shape of mass (n = 22)was concerned,the oval shaped lesion(13 cases)was the most common,and the margin of the mass appeared as ill-defined in 15 eases,microlobulated in 1,circumscribed in 4,and obscured in 2,respectively.Isodensity mass had a higher frequency in this group(12/22,55%).Other non-calcification findings included architecture distortion(7 cases),local asymmetry (15 cases),global asymmetry (5 cases),and solitary dilated duct (3 cases),and most of them accompanied with other signs. (3)For expression profile of the biological factors,significant differences were found among malignant calcification group,intermediate concern calcification group,and non-calcification group. The odds of PR positive for the lesions noted as non-calcification were 11.00 times higher (X~2 =8.571 ,P=0.003 ;95% CI, 1.998—60.572)than the lesions noted as intermediate concern calcifications,and 8.80 times higher (X~2 = 9.748,P=0.002 ;95% CI,2.024—38.253)than the lesions noted as malignant calcifications.The odds of C-erbB-2 positive for the lesions showed as malignant calcifications were 12.35 times higher (X~2=7.353, P=0.007 ;95% CI,1.447—105.443)than the lesions showed as non-calcification,and 5.74 times higher (X~2=4.977,P = 0.026;95% CI,1.110—29.645)than the lesions showed as intermediate concern calcifications.Conclusion The mammographic features of DCIS and DCIS with small invasive foci were characteristic.Mammographic findings could be a prognostic markers,which could provide a possibility for making a treatment plan.

Background and purpose: Arginase-1 (Arg-1) is an enzyme involved in the urea cycle. Research has shown that changed expression of Arg-1 plays an important role in the cellular metabolism and growth. The purpose of this research was to investigate the expression of Arg-1 in hepatocellular carcinoma (HCC) and to analyze its correlation with clinicopathological features. Methods: The expression of Arg-1 protein and mRNA in 31 samples of HCC, paracancerous liver tissues and 12 samples of normal liver was detected by Western blot and reverse transcription-polymerase chain reaction (RT-PCR). The expression profiles of Arg-1 at protein level in 158 samples of HCC and paracancerous liver tissues were detected with high-throughput tissue microarray technique and immunohistochemistry. The relationships between Arg-1 expression and clinicopathological features were also analyzed. Results:The expression of Arg-1 mRNA and protein was signiifcantly decreased in HCC compared with the paracancerous liver tissues and normal liver tissues (F=57.83, 160.89; all P<0.01). The expression of Arg-1 in HCC was related to differentiation degree (F=10.41, 30.03; all P<0.01). And with tumor differentiation decreased, the expression level down-regulated. Immunohistochemistry revealed that Arg-1 protein was mainly located in the cytoplasm and nuclear. The expression rates of Arg-1 were 88%, 98.7%and 100%in HCC, paracancerous tissues and normal liver tissues, respectively. Statistical analysis revealed that Arg-1 protein staining rate was signiifcantly lower in tumor tissues than that in paracancerous tissues (χ2=14.7416, P<0.01) and normal liver tissues (χ2=4.1415, P<0.05). The Arg-1 expression was correlated with differentiation degree of HCC, vascular invasion and recurrence after operation (χ2=22.8459, 10.2639, 10.6368 respectively;all P<0.05), but not correlated with age, gender, the hepatitis B virus, the level of serum AFP, liver cirrhosis, diameter of tumor and tumor number. Conclusion:The expression level of Arg-1 is much lower in HCC than that in the paracancerous liver and normal liver. Moreover, Arg-1 expression level is closely related to tumor differentiation degree, metastasis and relapse. These data demonstrate that Arg-1 may play a negative role in the development of HCC.

Objective To investigate the diagnostic value of digital breast tomosynthesis (DBT) plus full-field digital mammography (FFDM) in benign and malignant breast disease.Methods The prospective study enrolled 46 consenting women with a clinical suspicious of breast lesion confirmed by pathology. All the patients underwent DBT, FFDM and dedicated breast magnetic resonance image (DB-MRI) examinations before surgery or biopsy. To observe the manifestation of breast disease in different examinations according to breast imaging reporting and data system (BI-RADS), and to evaluate the visibility grade of disease between DBT plus FFDM and FFDM alone. Using receiving operating characteristic(ROC) and Z test to analysis the diagnostic efficiency of three examinations.Results Forty-six cases included 14 benign cases and 32 malignant cases. Compared with FFDM, 35 cases showed increased visibility in DBT plus FFDM, that the malignant lesion manifested mass with speculated and architectural distortion(23/27) and the benign lesion manifested mass with halo sign(6/8). Eleven cases didn't show increase visibility in both DBT plus FFDM and FFDM alone. The ration of BI-RADS 0 in FFDM was 23.9%(11/46), meanwhile in other two examination were 0. The ration of BI-RADS 3 in DBT plus FFDM was the lowest(6.5%, 3/46). When the lesion in DBT plus FFDM showed mass or speculated, in MRI showed similar morphology with mass or mass-like enhancement. According pathology as the gold standard, excluded 11 cases with BI-RADS 0 in FFDM, there was significant statistical difference between DBT plus FFDM and FFDM alone in 35 cases (Z=2.132, P=0.033) to differentiate benign and malignant breast disease, the area of ROC curve were respectively 0.955, 0.878. There is no statistical difference between DBT plus FFDM and MRI in 46 cases (Z=0.502, P=0.616), the area of ROC curve were respectively 0.887, 0.908.Conclusion DBT combined with FFDM can improve both detection of breast lesion and diagnostic efficiency, while the performance value between DBT and MRI are equal.
