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.

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.

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.

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

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.

After treatment, the clinical symptom score dropped in group 1、2、3 (P0.05); serum levels of resistin decreased and adiponectin increased in group 1、4 (P0.05). More significant difference was observed in group 1、4 between the four groups about the serum level of resistin、adiponectin、Leptin、TNF-?、CRP、IL-6 (P

?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.
