Accumulating evidence has shown that neutrophil-lymphocyte ratio (NLR), as an assessment index for inflammatory response, is closely related to the prognosis of various malignant tumors. This article summarizes the research advances in the relationship of NLR with overall survival, disease-free survival, and pathological features of hepatocellular carcinoma and related mechanisms of action, and points out that NLR is a convenient, economic, and effective predictor for the prognosis of patients with hepatocellular carcinoma.

Objective:To investigate the effects and mechanisms of Yinzhihuang oral liquid on mice with high-fat diet induced non-alcoholic fatty liver disease (NAFLD).Methods:Eighteen C57BL/6J female mice were divided into normal diet group, high-fat diet group and Yinzhihuang oral liquid group, with six mice in each group. After hematoxylin-eosin staining, oil red O staining and Masson staining, pathological scores of liver biopsy slices were calculated. Plasma levels of triacylglycerol, total cholesterol, total bilirubin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were tested. The composition of bile acid in mouse ileum content were measured by high performance liquid chromatography-tandem mass spectrometry, which included tauro-β-muricholic acid (TβMCA), ursodeoxycholic acid (UDCA) and cholic acid. The expression of farnesoid Ⅹ receptor ( FXR), fibroblast growth factor 15 ( FGF15), fibroblast growth factor receptor 4 ( FGFR4) genes at mRNA and protein levels and cytochrome P450 (CYP) 27a1, CYP7b1, CYP7a1 and CYP8b1 were detected by real-time quantitative polymerase chain reaction, Western blotting and immunohistochemistry, respectively. T test was used for statistical analysis. Results:The levels of plasma triacylglycerol, total cholesterol, total bilirubin, ALT and AST of Yinzhihuang oral liquid group were all lower than those of the high-fat diet group ((1.47±0.07) mmol/L vs. (1.90±0.13) mmol/L, (2.57±0.17) mmol/L vs. (6.84±0.23) mmol/L, (0.88±0.22) mg/dL vs. (2.06±0.25) mg/dL, (28.43±3.16) U/L vs. (87.15±23.27) U/L, (147.40±8.47) U/L vs. (289.00±12.66) U/L, respectively), and the differences were statistically significant ( t=3.90, 15.19, 4.31, 2.50 and 9.58, all P<0.05). The scores of adiposis and ballooning of hepatocytes of Yinzhihuang oral liquid group were lower than those of the high-fat diet group (1.00±0.26 vs. 2.33±0.33, 0.33±0.21 vs. 1.17±0.31, respectively), and the differences were all statistically significant ( t=3.90 and 4.90, both P<0.05). The levels of FXR antagonistic bile acids TβMCA and UDCA in ileal contents of Yinzhihuang oral liquid group were both higher than those of high-fat diet group ((4.95±0.68) nmol/g vs. (2.64±0.15) nmol/g, (7.86±1.84) nmol/g vs. (2.22±0.38) nmol/g, respectively), and the differences were statistically significant ( t=3.92 and 2.99, both P<0.05). The level of FXR agonistic bile acid cholic acid of Yinzhihuang oral liquid group were lower than that of the high-fat diet group ((4.69±0.46) nmol/g vs. (21.66±3.25) nmol/g), and the difference was statistically significant ( t=5.14, P<0.05). The expression of FXR, FGF15 in ileal tissues and FGFR4 in hepatic tissues at mRNA and protein levels of Yinzhihuang oral liquid group were all lower than those of the high-fat diet group (1.86±0.40 vs. 4.25±0.70, 9.99±2.82 vs. 75.17±23.41, 4.76±0.63 vs. 12.66±1.39, 2.20±0.14 vs. 5.30±0.25, 1.15±0.05 vs. 3.05±0.16 and 1.73±0.09 vs. 2.37±0.21, respectively), and the differences were statistically significant ( t=2.56, 2.76, 4.87, 10.90, 10.96 and 2.94, all P<0.05). The levels of CYP27a1 and CYP7b1 in the alternative pathway of bile acid synthesis in Yinzhihuang oral liquid group were both higher than those in the high-fat diet group (2.13±0.33 vs. 0.50±0.09 and 2.95±0.60 vs. 0.37±0.19), and the differences were statistically significant ( t=5.22 and 3.20, both P<0.05). But the expression level of CYP8b1 in the Yinzhihuang oral liquid group was lower than that in the high-fat diet group (2.38±0.41 vs. 8.63±2.20), and the difference was statistically significant ( t=2.80, P<0.05). Conclusion:Yinzhihuang oral liquid can reduce NAFLD by promoting bile acid synthesis through changing the components of intestinal bile acids in mice and inhibiting FXR-FGF15 signal pathway.

Objective: To investigate the pathogen spectrum distribution and drug resistance of febrile neutropenic patients with hematological diseases in Shanghai. Methods: A retrospective study was conducted on the clinical isolates from the febrile neutropenic patients hospitalized in the departments of hematology in 12 general hospitals in Shanghai from January 2012 to December 2014. The drug susceptibility test was carried out by Kirby-Bauer method. WHONET 5.6 software was used to analyze pathogenic bacteria and drug susceptibility data. Results: A total of 1 260 clinical isolates were collected from the febrile neutropenic patients. Gram-positive bacteria accounted for 33.3% and Gram-negative bacteria accounted for 66.7%. Klebsiella pneumoniae (12.5%) , Stenotrophomonas maltophilia (9.5%) , Escherichia coli (9.1%) , Pseudomonas aeruginosa (8.7%) , Acinetobacter baumannii (6.6%) , Staphylococcus aureus (5.6%) and Enterococcus faecium (5.0%) were ranked in the first 7 of all pathogens. In the respiratory tract secretions specimens, non-fermented strains accounted for 56.2%. Stenotrophomonas maltophilia accounted for 15.2%. Enterobacteriaceae and coagulase-negative Staphylococci accounted for 42.3% (104/246) and 32.6% (85/246) respectively in blood samples. Enterobacteriaceae and Enterococcus bacteria accounted for 39.4% (76/193) and 28.5% (55/193) respectively in pus specimens. The detection rates of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative Staphylococci (MRCNS) were 54.3% and 82.5%, respectively. Staphylococcus bacterial strain was not found to be resistant to linezolid, vancomycin and teicoplanin. The detection rate of Enterococcus vancomycin-resistant strains was 8.9%. Enterococcus was not detected resistance to oxazolidinone strains. Enterobacteriaceae bacteria were highly sensitive to carbapenems. The resistance rate of Pseudomonas aeruginosa to imipenem and meropenem was 34.1% and 15.8%, respectively. Stenotrophomonas maltophilia was more sensitive to minocycline hydrochloride, levofloxacin and sulfamethoxazole. The resistance rate of Acinetobacter baumannii only to cefoperazone-sulbactam was less than 10.0%. The antibiotic resistance rate of Klebsiella pneumoniae, Stenotrophomonas maltophilia, Pseudomonas aeruginosa and Acinetobacter baumanii to most of common antibiotics was lower than that of the CHINET surveillance. Conclusions The pathogenic strain distribution in common infection sites of febrile neutropenic patients was characterized. Bacterial resistance surveillance was better than the CHINET nationwide large sample surveillance in China.
