China Pharmacy 2016;27(7):923-925
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.

5.Expression of OPN protein in lung squamous cell carcinoma tissue and its clinical signiifcance
China Oncology 2015;(10):812-816
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.
6. Advance on population pharmacokinetic models of vancomycin
Chinese Pharmaceutical Journal 2013;48(24):2075-2080
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.

Chinese Journal of Rehabilitation Theory and Practice 2006;12(10):863-866
The heighten of the muscles tension is a familiar complication along with epigyny motoneuron's trauma. It's main manifestation is body spasm which badly affects the patients' daily life ability and the rehabilitation treatment. The measures of anti-convulsion are varied which include medicine, acupuncture, operation, electricity stimulates, and etc. But the problems such as the curative effect, the fee and the specialized technology limit application of those measures in clinic. Under the guidance of the modern rehabilitation theory, according to the scientific research design elements and method of the modern medicine research, combining the therapeutics of the traditional Chinese medicine and some modern rehabilitation technology, developing a sort of safe and effective integrative therapy method, which is a domain urgently needs to be exploited.

Objective:To investigate the expressions of peripheral lymph node addressin(PNAd)andGlcNAc-6-sulfotransferase(GlcNAc6ST)in endometrium and their impacts on implantation.Methods:PNAd expression in endometrium was examined by immunohistochemistry and Western Blot from 75women(12 from healthy women,in proliferative phase;63 from sterile women,of whom,27 were inearly-secretory and 36 in mid-secretory phase).GlcNAc6ST mRNA was examined by real-time PCR in41 sterile women.The 63 sterile women had underwent ⅣF-ET and were consequently divided into clini-cal pregnant(29 cases)and nonpregnant(34 cases)groups.Results:(1)PNAd localized to the mem-brane and cytoplasm of luminal and glandular epithelia.Staining was patchy and much less intense duringthe proliferative phase than during the secretory phase.In Western Blot of PNAd,four bands appeared,which were Sgp200,CD34,MAdCAM-1,GlyCAM-1 respectively,and each was positively correlatedwith the others significantly.The former three molecular levels were significantly higher during the secre-tory phase as compared with the proliferative phase.Message RNA of GlcNAe6ST was positive in all ca-ses and showed no correlation with any component of PNAd.(2)The expressions of CD34 and GlyCAM-1,but not Sgp200 and MAdCAM-1,were significantly higher in pregnant women than in nonpregnantones.However,the GlcNAc6ST mRNA level did not differ between groups.(3)No significant differ-ence was found in female age,methods of fertilization,thickness of endometrium on day hCG,cumulativeembryo score(CES)and mean score of transferred embryo(MSTE)between the groups.Conclusion:PNAd expression in the human endometrium fluctuates with the menstrual cycle.Elevated CD34 and Gly-CAM-1 during the secretory phase might be stimulative factors for embryo implantation.Defect in PNAdexpression may account for a portion of unexplained infertility.
