Objective To evaluate t he efficacy of fluoxetine in treating tinnitus patients with depress. Methods A randomized,open-labeled,controlled clinical tri al was conducted.There were 31 patients in control group and 26 p a tents in fluoxetine group.The efficacy was assessed by tinnitus patients with Ra ting Scale and Hamilton Depression Rating Scale (HAMD). Results The total effective rate of fluoxetine group was 71.11%, and there was significant improvement rate in depression after 1 month f luoxetine treatm ent. Conclusion Fluoxetine is an effective drug for tinnitus p atients with depression.

Genome sequencing and bioinformatics is driving the discovery of drug targets and development of novel classes of broad spectrum antimicrobial compounds. The analysis of the complete genome sequences of microorganism available in the public databases offers the first insights into the drug targets discovery. This review discusses the use of genomic information in the finding of target genes for antimicrobial drug discovery.

Objective To investigate the protective role of Xiongbitong capsule against liver injury in hyperlipemic rats.Methods Sixty Wistar male rats were randomly divided into 5 groups(12 rats in each group): a blank group, a model group, a simvastatin group(10 mg/kg, 2 ml intragastric administration daily), a Xiongbitong capsule high-dose group(25 mg/kg, 2 ml intragastric administration daily), and a Xiongbitong capsule low-dose group(12.5 mg/kg, 2 ml intragastric administration daily). Hyperlipidemia model in rats was indeuced by hyperlipidemic diet. The simvastatin group was intragastric administrated with simvastatin suspension 2 ml(10 mg/kg daily), and the rats in the control group and the model group were intragastric administrated with equal volume of saline. After 10 weeks, the serum leves of total cholesterol(TC), triacylglycerol(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol (HDL-C), nitric oxide(NO), endothelin1(ET-1), and the whole blood viscosities(high-, medium-, low-shear)were measured. Liver injury were evaluated with histopathologic examination by H.E. staining. The expressions of intercellular adhesion molecule-1(ICAM-1), monocyte chemoattractant protein-1(MCP-1)in hepatic tissue were measured by immunohistochemical staining.Results The serum leves of TC(1.47± 0.10 mmol/Lvs. 3.48±0.19 mmol/L), TG(0.38±0.11 mmol/Lvs. 0.95±0.14 mmol/L), LDL-C(1.48± 0.18 mmol/Lvs. 2.39±0.22 mmol/L), ET-1(145.81±18.65 pg/mlvs. 177.70±17.70 pg/ml) in the Xiongbitong capsule high-dose group were significantly lower than those in the model group(allP<0.01), HDL-C(1.21±0.14 mmol/Lvs. 0.65±0.10 mmol/L)and NO(31.28±2.36μmol/Lvs. 19.61±1.28μmol/L) significantly lower than those in the model group(allP<0.01), the expressions of ICAM-1(0.133±0.019vs. 0.187±0.011)and MCP-1(0.153±0.014vs. 0.264±0.020)significantly lower than those in the model group(allP<0.01). The liver injury in the Xiongbitong capsule high-dose group decreased than that in the model group. Conclusions Xiongbitong capsule can protect against liver injury via regulating lipid metabolism, protecting endothelial function and down regulating expressions of MCP-1 and ICAM-1.

Objective To prepare transferrin and Arg-Gly-Asp polypeptide co-modified nanoparticles(TF/RGD-NPs)and evaluate its targeting efficiency to melanoma.Methods The co-modified nanoparticles were prepared by emulsion method and its appearance,particle size and Zeta potential were evaluated.The cellular uptake experiment and melanoma tumor spheroids penetration test were used to evaluate the affinity and ability to penetrate tumor tissues of TF/RGD-NPs to melanoma B16 cells. Results The particle diameter of co-modified nanoparticles was(113.4 ±12.5)nm and the Zeta potential was(4.53 ±2.15)mV.In vitro uptake test demonstrated that the efficacy of cellular uptaken TF/RGD-NPs by B16 cells were 2.7 times and 2.9 times to TF-NPs and RGD-NPs,respectively,the differences were all significant(P<0.05 ).Tumor spheroid penetration test results showed that TF/RGD-NPs has good affinity to melanoma cells.Conclusion TF/RGD-NPs can target to melanoma B16 cell efficiency in vitro,it may be serve as a potential drug delivery system for targeting melanoma.

One of the biggest differences between ordinary undergraduate education and higher vocational education is more emphasis on the cultivation of students' vocational skills so as to adapt to so-cial demand and employment. In order to overcome the deficiencies in current teaching outline of voca-tional education and to change from subject knowledge teaching to applied skill cultivating , medical and health curriculum standard including 'curriculum philosophy, curriculum goal, curriculum content, curriculum implementation' four elements was formulated based on concepts of 'education as base , practice orientation and lifelong learning' and cultivation mode combining industry standard with cur-riculum teaching goal and combing work with study. All measures taken above were aimed at promoting coordinated development of students' knowledge, ability and emotion and satisfying the social demand for talent.

Objective To evaluate the effect of embelin combined with paclitaxel on the inhibition of A 549 lung cancer cell proliferation and tumor growing in tumor bearing nude mice. Methods The anti-proliferation efficiency of embelin combined with paclitaxel were evaluated by MTT assay, and A 549 cell apoptosis were evaluated by lfow cytometry. A 549 cells were xenografted in mice to establish the animal model, which were used to evaluate the effect of anti-tumor. Results compared to saline group、embelin group and paclitaxel group, the (paclitaxel+embelin) group could inhibit the growth of A 549 cells effectively(P<0.05). The embelin combined with paclitaxel induced the apoptosis of A 549 cells more effective than paclitaxel alone. The (paclitaxel+embelin) group significantly inhibited the growth of tumor tissue. Conclusion the paclitaxel can inhibit the growth of A 549 cells, the embelin can induce the apoptosis of A 549 cells, and the combination of paclitaxel and embelin may be a potentially effective treatment for lung cancer.

Objective To explore the effect of X-linked inhibitor of apoptosis protein(XIAP)combined with doxorubicin on the proliferation of MCF-7 cell and growth of MCF-7 bearing nude mice.Methods The anti-proliferation efficiency of doxorubicin and embelin were determined by MTT assay.MCF-7 cell apoptosis induced by embelin and doxorubicin were detected by Flow cytometry.Anti-tumor ability of embelin and doxorubicin were evalued with tumor spheroids test.MCF-7 cell were xenografted to mice to establish the animal model,which was used to evaluate the effect of anti-tumor. Results Compared with saline group,embelin group and doxorubicin group,the combination(doxorubicin +embelin)group inhibited the growth of MCF-7 cells effectively(P<0.01).The combination group induced the apoptosis of MCF-7 cells more effectively than doxorubicin alone(P<0.01), and significantly inhibit the growth of tumor in vitro and in vivo than other groups(P<0.01).Conclusion The combination of doxorubicin and embelin may be used as a potentially effective treatment method for breast cancer.
