WHO has issued three editions of pathologic classification of bladder urothelial carcinoma in 1973,1999 and 2004.The 1973 version classification had been widely and the longest applied.However,WHO 2004 classification had been prevalent in past years.There were two issues in the applications of WHO 2004 classification.On one hand,there were some difficulties in quick grading in a given case.On the other hand,there were some misunderstandings in the conversion of different WHO classification.In this article,the changes of different pathologic classification of bladder urothelial carcinoma were reviewed and the outline of different pathologic classification was generalized.The criterion of all the systems was cell anaplasia.In WHO 1973 version classification,the definition of the various grades was vague.It was relatively precise in WHO 1999 classification.However,the grading of Ⅰ,Ⅱ and Ⅲ in WHO 1999 classification still remained confusions.The major changes in WHO 2004 classification was that this system divided urothelial carcinoma into low-and high-grade,which may solve the heterogenesis of grade Ⅱ in the other two classifications.

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.
