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.

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.

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 investigate the expression and clinicopathological significance of CXCR4 and HIF-1α protein in esophageal squamous cell carcinoma tissue and explore their correlation.Methods The expression of CXCR4 and HIF-1α protein were assessed by immunohistochemistry SP method in 56 cases with esophageal squamous cell carcinoma and in 20 cases with surrounded normal tissue.Results The expressions of CXCR4 and HIF-lα in esophageal squamous cell carcinoma were significantly higher than those in normal tissues[62.50 ％ (35/56) vs 10.00 ％ (2/20); 57.14 ％ (32/56) vs 0(0/20)](x2=16.259,19.740,P ＜0.01).The expression of CXCR4 and HIF-1α were both correlated with invasion depth (x2 =4.736,7.665,P ＜0.05) and lymph node metastasis ( x2 =7.207,6.389,P ＜0.05),and had no correlation with cancer cell differentiation.The expressions of CXCR4 and HIF-lα in esophageal squamous cell carcinoma were positively correlated (r =0.298,P ＜0.05).Conclusion CXCR4 and HIF-1α are highly expressed in esophageal squamous cell carcinoma.The two have a close relation to esophageal squamous cell carcinoma growth,invasion and metastasis.

Objective The frequency and the anatomic distribution of involved regional nodes in recurrent and locally advanced breast cancer were analyzed, in order to evaluate the rational of conventional regional node radiation technique and provide evidence for target definition of breast cancer . Methods Patients with recurrent or locally advanced breast cancer who were treated in our hospital from August 2003 to December 2009 were included in this study. 111 patients had contrast enhanced chest CT images of the whole regional nodes before treatment. The regional nodes were categorized into 8 anatomical substructures including medial and lateral supraclavicular nodes ( SC-M, SC-L), axilla nodes ( ALN )- Ⅰ , Ⅱ , Ⅲ,infraclavicular nodes (IFN), Rotter's nodes (RN) and internal mammary nodes (IMN). The frequency of involvement and anatomical distribution of the involved nodes on CT images were analyzed. Results A total of 111 patients were enrolled this study and 199 anatomical substructures with involved nodes were identified. The frequency of involvement were :SC-M 33, SC-L 21, ALN- Ⅰ 30, ALN-Ⅱ 25, ALN-Ⅲ + IFN 35, RN 27, IMN 28. Supraclavicular region and axilla were the most frequently involved area (72. 3% ).The average depth of the SC-M and SC-L nodes was 33.48 mm ± 10. 57 mm and 45.62 mm ±20. 45 mm,and 51.5% and 71.4% of the SC-M and SC-L nodes were located more than 3 cm deep from the skin. The axilla nodes were located cranial and caudal to the axillary vein in 5 and 20 locally advanced breast cancer patients and in 64 and 28 patients who received prior axillary dissection. The majority of involved IMN was located within the first 3 intercostal spaces (26/28). The average distance between the center of involved IMN and chest skin was 24. 23 mm ± 10. 28 mm. The average distance between the center of involved IMN and midline of the body was 29. 38 mm ±6. 7 mm. The center of involved IMN was 6.19 mm ±5.73 mm lateral and 5.73 mm ± 4. 56 mm posterior to the internal mammary vessels. Conclusions Conventional field design is unlikely to provide sufficient dose to the entire risk region because of individual differences.Individualized treatment planning based on CT would become feasible with increasing knowledge of natural risk of nodal involvement.
