Objective: To execute a hierarchical cluster of clinical laboratory indicators in patients with bunyavirus infection. Methods: From July 2015 to July 2017, 14 patients with bunyavirus infection in Zhoushan Hospital were selected.The blood routine, coagulation function and biochemical indicators were detected.Cluster analysis and grouping were carried out by hierarchical clustering method. Results: Hierarchical clustering classification was eventually divided into 2 cases of A category[with TT high and BNP high as the main characteristics(TThighBNPhigh)] and 12 cases of B category[with TT low and BNP low as the main characteristics (TTlowBNPlow)]. The days of hormone drugs and dosage of hormone drugs in A category were (7.43±3.53)d, (489.19±173.02)mg, respectively, which were higher than those in B category[(5.20±1.03)d and (115.11±46.58)mg], the differences were statistically significant(t=2.76, 55.56, all P<0.05). Conclusion It needs probably to pay more days and dose of hormonal drugs for patients with TThighBNPhigh.

Objective: To investigate the clinical value of biochemical indicator and hepatic fibrosis in differential diagnosis of patients with cirrhosis and chronic liver failure. Methods: From December 2015 to December 2018, 30 patients with cirrhosis and 30 patients with chronic liver failure in Zhoushan Hospital were selected.The serum levels of ALT, AST, TBil, hyaluronic acid (HA), laminin (LN), PC-Ⅲ, collagen type Ⅳ(Ⅳ-C) were detected. Results: The serum levels of ALT, AST and TBil in patients with cirrhosis were significantly lower than those in patients with chronic liver failure[(258.17±88.19)U/L vs.(818.37±375.83)U/L; (256.57±97.21)U/L vs.(738.63±329.68)U/L; (51.37±22.13)μmol/L vs.(157.27±85.60)μmol/L, t=-7.95, -7.68, -6.56, all P<0.01]. The serum levels of HA, LN, PC-Ⅲ and Ⅳ-C in patients with cirrhosis were significantly higher than those in patients with chronic liver failure[(433.10±214.39)μg/L vs.(81.56±27.80)μg/L; (157.67±52.60)μg/L vs.(66.06±24.06)μg/L; (126.63±35.24)μg/L vs.(70.96±19.71)μg/L; (162.26±53.93)μg/L vs.(76.13±27.90)μg/L, t=8.90, 8.67, 7.49, 7.76, all P<0.01]. When patients with chronic liver failure were set as state variable, AUC of ALT(0.973) was the highest in ALT, AST, TBil.When patients with cirrhosis were set as state variable, AUC of HA(0.993) was the highest in HA, LN, PC-Ⅲ and Ⅳ-C. Conclusion ALT and HA are suitable for differential diagnosis of patients with cirrhosis and chronic liver failure.
