Molecular target-based cancer therapy is playing a more and more important role in cancer therapy because of its high specificity, good tolerance and so on. There are different kinds of molecular targeted drugs such as monoclonal antibodies and small molecular kinase inhibitors, and more than 50 drugs have been approved since 1997. When the first monoclonal antibody, rituximab, was on the market. The development of molecular target-based cancer therapeutics has become the main approach. Based on this, we summarized the drugs approved by FDA and introduced their mechanism of actions and clinical applications. In order to incorporate most molecular targeted drugs and describe clearly various characteristics, we divided them into four categories: drugs related to EGFR, drugs related to antiangiogenesis, drugs related to specific antigen and other targeted drugs. The purpose of this review is to provide a current status of this field and discover the main problems in the molecular targeted therapy.

0.05). Conclusion Enough high-purified LECs can be isolated by collagenase digestion procedure followed by immunomagnetic beads sorting. Post-thawed endothelial cells are proved to have high vitality and growth potential in vitro without significant morphological changes. Cryopreserved LECs may serve as a cell choice for research of lymphangiogenesis and lymphatic patterning.

AIM:To investigate the effect and the mechanism of Zhibai Dihuang Pill(Radix Rehmanniae praeparata,Fructus Corni,Rhizoma Dioscoreae,Rhizoma Anemarrhenae,Cortex phellodendri Chinensis,etc.) on patients with hyperthyroidism. METHODS: Eighty-five hyperthyroid patients were randomly divided into two groups.The control group(40 cases) were treated with propylthiouracil,while the treatment group(45 cases) were treated with propylthiouracil and Zhibai Dihuang Pill;in the 12-week long treatment period,the heart rate,body weight,thyroid free FT_3、FT_4 and TSH and the serum level of FAA,resistin,adiponectin,leptin of patients in both groups were measured. RESULTS: After treatment,the heart rate,the serum of FT_3,FT_4 decreased and the body weight,TSH increased in both groups(P0.05).(CONCLUSION): Zhibai Dihuang Pill can improve the abnormal metabolism of sugar and fat in patients with hyperthyroidism by its actions on the serum level of FFA,resistin,adiponectin,leptin.

Objective To study the effect of dialysis adcquacy,microinflammation and residual renal function on nutritional status of hemodialysis patients.Methods One hundred and fourteen patients were enrolled in this study.Kt/V,?_2-MG and serum iPTH were measured as markers of hemodialysis adequacy.Nutritional evaluation included MQSGA,Alb,Hb,TF,IGF-1,IGFBP-3 and anthropometrics such as HGS,BSF,TSF,MAC,MAMC and AMA.Serum IL-6,TNF-?and CRP were detected to assess microinflammation.Urinary volume of 24 hours was measured to investigate the residual renal function (RRF).Results (1)There were different correlations and regressive associations of Kt/V,iPTH and?_2-MG with HGS,MAMC,AMA,Alb,Hb,nPCR,IGF-1 and MQSGA respectively.(2) There were significant correlations and regressive associations of RRF to HGS,TSF,MAMC,Alb,nPCR and IGF-1 within the first year of hemodialysis.(3) There were different correlations and regression relationships of IL-6,TNF-?and CRP with HGS、MAMC、AMA、Alb、TSF、Hb、nPCR、IGF-1 respectively.(4) Multivariate analysis showed that Kt/V,iPTH,IL-6, TNF-?,?_2-MG and RRF were influencing factors,among them,Kt/V,iPTH,IL-6 and TNF-?were independent predictors of nutritional status.Conclusions Hemodialysis adequacy and micruinflammation may impact on nutritional status.Residual renal function may be involved in nutritional status in the first year of hemodialysis.Kt/V,iPTH,IL-6 and TNF-?are independent factors affecting nutritional status.

Background and purpose:It was reported that chemokine receptor CXCR4 and its ligand stromal cell-derived factor 1(SDF-1)were involved in the proliferation,differentiation,and metastasis of tumor.This study was designed to observe the expression of chemokine receptor CXCR4 in hypopharyngeal squamous cell carcinoma tissue and study the relationship between the expression of chemokine receptor CXCR4 and different clinicopathlogical characteristics,and further to explore the clinical significance.Methods:For the detection of the expression of chemokine receptor CXCR4,43 primary hypopharyngeal squamous cell carcinoma tissues,27 normal hypopharyngeal tissues,34 lymph node metastastatic lesions and 9 normal lymph node lesions were detected by immunohistochemical method using rabbit anti-human CXCR4 polyclonal antibody.Results:The positive expression rates of CXCR4 in 43 hypopharyngeal carcinoma tissues and normal tissues were 95.3% and 22.2%,respectively(P

The technique of liquisolid compress is a new technique developed in 1990s, which was considered to be the most promising technique to improve the dissolution of water-insoluble drugs. In this article, tanshinone II(A) and the extracts of the ester-solubility fractions were chosen as the model drugs to evaluate the effects of the liquisolid technique for enhancement of dissolution properties of tanshinone II(A). Several liquisolid tablets (LS) formulations containing different dosage of drugs and various liquid vehicle were pre-pared and for all the formulations, microcrystalline cellulose and silica were chosen as the carrier and coating materials to evaluate their flow properties, such as angle of repose, Carr's compressibility index and Hausner's ratio. The interaction between drug and excipients in prepared LS compacts were studied by differential scanning calorimetry(DSC) and X-ray powder diffraction (XRPD). The dissolution curves of tanshinone II(A) from liquisolid compacts were investigated to determine the technique's effect in improving the dissolution of tanshinone II(A) and its impacting factors. According to the results, the dissolution increased with the rise in the dissolution of the liquid-phase solvent. The R-value and drug dosage can significantly affect the drug release, but with less impact on active fractions. This indicated that liquisolid technique is a promising alternative for improvement of dissolution property of water-soluble drugs, and can make a synergistic effect with other ester-soluble constituents and bettern improve the release of tanshinone II(A). Therefore, the technique of liquisolid compress will have a better development prospect in traditional Chinese medicines.

OBJECTIVETo observe the clinical efficacy of TCM for reinforcing Shen and activating blood circulation to dredge Channels in auxiliary treating chronic aplastic anemia (CAA), and to explore its mechanism.

METHODSSeventy-nine patients with CAA were randomly divided into the treated group treated with TCM plus western medicine and the control group treated with western medicine alone. The clinical efficacy was observed and levels of plasma sFas and sFasL before and after treatment were determined by ELISA.

RESULTSThe basic cure rate and total effective rate in the treated group were 37.50% and 87.50%; while in the control group were 20. 51% and 61.54% respectively. Comparison between the two groups showed significant difference (P < 0.01). The sFas level was markedly lower in both groups before treatment, but after treatment, it got elevated in the treated group significantly (P < 0.05), as compared with that in the control group, the difference was significant (P < 0.01).

CONCLUSIONTCM is effective in treating CAA with less toxic and side-effect, the mechanism might be the inhibition on over apoptosis of hematopoietic cells in CAA patients through regulating immune function of organism.

Objective To examine the levels of serum adipunectin (ADPN)in patients with end-stage renal disease (ESRD), and identify the relationship between serum ADPN and tumor necrosis factor (TNF)-α, high sensitivity C-reactive protein(hs-CRP) and renal function. Methods Sixty ESRD patients and twenty normal healthy persons were involved in this study. The patients were divided into three groups: patients with chronic renal failure (CRF, 18 cases), patients with hemodialysis (HD,22 cases) and patients with peritoneal dialysis (PD,20 cases). The levels of serum ADPN, TNF-α and hs-CRP were detected by means of ELISA. Differences in continuous variables be-tween the three groups were evaluated. Results The levels of serum ADPN, TNF-α and hs-CRP in CRF, HD and PD patients were signifi-cantly higher than those in control group ( P<0.01 ). Serum ADPN levels in ESRD patients were positive related to serum TNF-α( r≥0.478, P<0.01 ), and negative related to GFR ( r≥-0.582, P<0.01 ). Conclusion The level of serum ADPN was markedly in-creased in patients with ESRD, and correlated with serum TNF-α level and.renal function.
