Objective To evaluate the outcomes of maxillary protraction in the treatment of skeletal class Ⅲ malocclusions in early mixed dentition. Methods Fourteen patients with skeletal class Ⅲ malocclusions in early mixed dentition were treated with maxillary protraction for one year with oral active appliance bonded face mask.Cephalometric records were analyzed to assess the changes of maxillo-facial structure of the hard tissue before and after treatment. Results The anterior crossbite was unlocked in all the patients,and the maxilla moved downwards and forwards.Point A moved forwards,and angle SNA and ANB significantly increased.The mandible rotated downward and backward,and the Wits values significantly increased,which led to the correction of a skeletal class Ⅲ relationship.Maxillary length and protrusion significantly increased,and facial profile improved obviously. Conclusion Maxillary protraction works well in the treatment of skeletal class Ⅲ malocclusions in early mixed dentition,and can reduce the chances of later orthognathic surgery.

Remaining organic and functional damage of ischemia cardio-cerebrovascular disease is always a main trouble puzzling the clinicians. After the discovery of endothelial progenitor cells (EPCs), researchers realize that postnatal angiogenesis is an important biological process, which play a key role to repair the ischemia tissue and improve the function. So a new concept which names therapeutic angiogenesis supply a new treament way for the ischemia cardio-cerebrovascular disease. Traditional Chinese medicine (TCM) has accumulated rich experience on treating the ischemia disease, studies found that many Chinese medicine prescriptions and effective ingredients can increase the therapeutic angiogenesis, howerer the mechanisms were not the same, they mainly manifest in regular the secretion of angiogenic factors, increase the proliferation and differentiation etc. In this paper, we review recent studies, summary the Chinese medicine prescriptions and effective ingredients which can increase the therapeutic angiogenesis, and analyze the differernt pathway. We view to provide reference for the later researchers.

There are many different opinions about the taxonomy of plant pathogenic coryneform bacteria since they were departed from genus of Corynebacteria. In recent years, they were classified into 5 genus, including Clav-ibacter, Curtobacterium, Arthrobacter, Rhodococcus and Rathayibacter. Some new points of view about their taxonomy have been published thereafter. The changing of taxonomy is maily because of the methods'altering from old to new molecular and polyphasic taxonomy, and the latter is in continuously development. Taxonomy of plant pathogenic coryneform bacteria somehow depends on the cooperation of phytopathologists, microbilogists and other scientists.

OBJECTIVETo observe the efficacy on primary osteoporosis treated with spreading moxibustion for warming yang and activating blood circulation so as to provide the effective clinical therapeutic methods for osteoporosis.

METHODSSixty cases of primary osteoporosis were randomized into a spreading moxibustion group (30 cases) and a calcium tablet group (30 cases). In the calcium tablet group, caltrate was prescribed for oral administration, 600 mg per day. In the spreading moxibustion group, on the basis of the treatment as the calcium tablet group, the spreading moxibustion was applied at Dazhui (GV 14) to Yaoshu (GV 2) for warming yang and activating blood circulation. The duration of treatment was 12 weeks. Visual analogue scale (VAS) score, TCM clinical symptom score and bone mineral density (BMD) were observed and compared before and after treatment in the patients between the two groups.

RESULTSVAS scores were reduced apparently after treatment in the two groups (both P < 0.01) and the results in the spreading moxibustion group were obviously superior to that in the calcium tablet group (2.36 +/- 0.43 vs 4.52 +/- 0.35, P < 0.01). BMD were all increased in the two groups (P < 0.05, P < 0.01) and the results in the spreading moxibustion group were superior to those in the calcium tablet group (both P < 0.05). The total clinical effective rate was 86.67% (26/30) in the spreading moxibustion group, apparently better than 63.33% (19/30) in the calcium tablet group (P < 0.05). TCM clinical symptom scores after treatment were all reduced apparently in the two groups (both P < 0.01), and the result in the spreading moxibustion group was obviously superior to that in the calcium tablet group (4.72 +/- 1.90 vs 6.82 +/- 2.30, P < 0.01). The total effective rate of TCM symptoms was 93.33% (28/30) in the spreading moxibustion group, apparently better than 70.00% (21/30) in the calcium tablet group (P < 0.05).

CONCLUSIONThe combined therapy of spreading moxibustion for warming yang and activating blood circulation and the oral administration of caltrate apparently relieves pain and TCM clinical symptoms, improves BMD in the patients of osteoporosis and achieves definite clinical efficacy in the patients of osteoporosis.

OBJECTIVE To explore the role of gecko crude peptides (GCPs) in the proliferation, apoptosis, migration and lymphangiogenesis of human hepatocellular carcinoma cells (HepG2) and human lymphaticendothelial cells (HLECs) in vitro. METHODS The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate the anti- proliferative effect of GCPs and siRNA-VEGF-C on HepG2 cells, Hoechst 33258 staining and flow cytometry were performed to analyze cycle and apoptosis. The migration and invasion ability of cells were assayed by transwell chamber experiment and wound-healing assay. The protein and mRNA expressions of vascular endo?thelial growth factor-C (VEGF-C) and CXC chemokine receptor-4 (CXCR4) were detected by q-PCR, immunofluorescence, Western blot. The protein expressions of the extracellular signal regulated kinase (ERKI/2), c-Jun N-terminal kinase (JNK), p38-mitogen activated protein kinases (p38 MAPK), serine/threonine kinase (Akt) and phosphatidylinositol- 3- kinase (PI3K) were detected by western blot. The anti-lymphangiogenesis effect of GCPs on the HLECs was analyzed using an in vitro tube-formation assay. The protein and mRNA expressions of vascular endothelial growth factor receptor-3 (VEGFR-3) and stromal cell-derived factor-1 (SDF-1) were detected by q-PCR, Western blot. RESULTS GCPs and siRNA-VEGF-C inhibited HepG2 proliferation, invasion and migration, and the most obvious inhibitory effect was both synergistic effects. Thus, GCPs suppressed HLECs proliferation, migration and tube-like structure formationin a dose- dependent manner, and had inhibitory effect of tumor- induced lymphangiogenesis in vitro. Additionally, we found that GCPs and siRNA- VEGF- C decreased the expressions of MMP-2, MMP-9, VEGF-C, CXCR4, phospho-ERK1/2, phospho-P38, phospho-JNK and PI3K in HepG2 cells. Moreover, GCPs had a dose-dependent depressive effecton the expressions of VEGFR- 3, SDF- 1 in HLECs. CONCLUSION The low expression of VEGF- C mediated by siRNA-VEGF-C and GCPs inhibit tumor proliferation, invasion and migrationby suppressing the MAPK signaling pathway through reduced levels of VEGF-C, and GCPs inhibit tumor lymphangiogenesis by suppressing the CXCR4/SDF-1 signaling pathway through suppressed VEGF-C/VEGFR-3.
