Background and purpose:Osteopontin (OPN) is a secreted glyco-phosphoprotein, which is overex-pressed by numerous human cancers, invovled in tumor occurrence, development and prognosis. OPN up-regulates matrix metal proteases (MMPs) expression in a NF-κB-dependent fashion during extracellular matrix (ECM) invasion causing degradation of cell basement membrane and ECM leading to tumor invasion and metastasis. The aim of this study was to examine the protein level of OPN in a large number of tissue samples from patients with lung squamous cell carcinoma (SCC), and evaluate its potential clinical value.Methods:The OPN protein levels in 265 tumor tissue samples and corresponding 24 normal lung tissue samples were examined by immunohistochemical (IHC) analysis.Results:IHC results showed that the positive rate of OPN was 64.5% in the SCC tissues, which was significantly higher than that in normal alveoli tissues (29.2%,P<0.001). The positive rate of OPN expression in late stage (Ⅲ+Ⅳ) tissues was 78.4%, significantly higher than that in early stage (Ⅰ+Ⅱ) tissue(positive rate 54.5%,P<0.001). The positive rate of OPN expression in T3-4 stage (Ⅲ+Ⅳ) tissue was 76.9%, significantly higher than that in T1-2 stage tissue (positive rate 59.4%,P=0.007). The expression of OPN was signifcantly correlated with the status of lymph node metastasis (LNM). The positive rate in the tumor tissue with LNM was 73.4%, significantly higher than that without (positive rate 51.4%,P<0.001).Conclusion:The level of OPN protein was overexpressed in lung cancer tissues, involved in SCC carcinogenesis and LNM. It is indicated that OPN has an impor-tant reference value in diagnosis, prognosis and therapy of SCC.

OBJECTIVE:To compare the distribution of levofloxacin in lung of mice after intragastric and intravenous adminis-tration of Tanreqing injection combined with levofloxacin. METHODS:144 mice were randomly divided into experimental group and control group,with 72 mice in each group. Both groups were given Tanreqing injection(0.8 ml/kg). 1 h later,control group was given Levofloxacin injection(80 mg/kg)intravenously,and experimental group Levofloxacin tablet solution(80 mg/kg)intra-gastrically;every 8 mice were sacrificed for lung tissue collection at the time points of 0.05,0.083,0.17,0.5,1.0,2.0,4.0,8.0, 12.0 h and 0.083,0.17,0.33,0.5,1.0,2.0,4.0,8.0,12.0 h,respectively. Using ciprofloxacin as internal standard,the content of levofloxacin in lung tissue was determined by HPLC,and pharmacokinetic parameters were calculated by 3p97 program. RE-SULTS:The concentration-time curves of levofloxacin in lung tissue were in line with two-compartment model in 2 groups. The main pharmacokinetics of experimental group and control group were as follows as t1/2β of(4.17±0.84)h and(4.10±0.55)h;CL of(0.66±0.049)L/h and(0.71±0.21)L/h;AUC0-t of(109.48±12.34)mg·h/kg and(113.04±29.43)mg·h/kg;cmax of(38.76± 1.62) mg/kg and (42.28 ± 2.03) mg/kg,respectively. There was no statistical significance (P>0.05). Absolute bioavailability of levofloxacin was(96.85±17.39)% in experimental group with intragastric administration. CONCLUSIONS:After intravenous injec-tion of Tanreqing injection,the distribution of levofloxacin in lung tissue of mice are similiar between intragastric administration and intragastric administration.

OBJECTIVE: To review population pharmacokinetics of vancomycin in recent years, and to provide methods for rational application vancomycin in clinical practice. METHODS: According to literatures, population pharmacokinetic models of vancomycin were reviewed. RESULTS AND CONCLUSION: Population pharmacokinetic models were better reasonable to predict accurate pharmacokinetic parameters of individuals, especial for the subpopulations, such as children, severe obesity, cancer and so on. They could help clinicians to select proper dosing of vancomycin to individualize the therapy in different patient populations. This way could reduce side effects and resistances of vancomycin through individualized administration.
