Objective:To discuss the X-ray digital tomosynthesis (Digital Tomosynthesis, DTS) application value in the occult fractures of the scaphoid. Methods: we selected 19 patients in our hospital in 2012 examined by DTS, who were negative or highly suspicious of occult fracture with X-ray examination, and spiral CT (SCT) three-dimensional (3D) reconstructions were applied in seven patients. Results:There were 17 patients with fracture by DTS.7 patients showed fracture by spiral CT(SCT) three-dimensional(3D) reconstructions. Conclusion:Compared with X-ray examination, the image quality of Digital Tomosynthesis (DTS) is higher, which can show occult fracture better. Compared with CT, DTS can show spatial location of bony anatomy more clearly and can obtain more detailed information. With the important extension and supplement of CT and MRI, the distal tomosynthesisis is worth to be generalized for lower radiation, lower price, higher positive rate and high quality of the pictures.

Objective To investigate the expression of c-erbB-2 in breast cancer and its relationship with prognosis.Methods The expression of c-erbB-2 in breast cancer was detected by immunohistochemistry assays in 60 cases of breast cancer.Results The positive expression level of c-erbB-2 in invasive breast cancer was signifi-cantly higher than that in other kinds of breast cancer(P<0.01).The positive expression level of c-erbB-2 in the metastatic breast cancer with four lymph nodes was higher than in the early cancer with no lymph node involvement (P<0.01).The 10 years survival rate in negative expression of c-erbB-2 was higher than in positive expression(P<0.05).Conclusion c-erbB-2 is important for physicians to instruct the treatment of the breast cancer and judge the prognosis.

Objective To observe the curative effects of Jawei-Wendan decoction in treating acute exacerbation of COPD due to phlegm blocking in lung. Methods From July 2010 to June 2013, 66 enrolled cases were randomly divided into a treatment group and a control group with 33 in each. Aside from receiving anti-infection and symptomatic treatment as the control group did, the treatment group was also given orally Jawei-Wendan decoction. The symptoms, pulmonary function and the variety of the laboratory indexing were observed before and after the treatment. Results ①The treatment group attained better curative effects(P<0.05) and got shorter symptomatic relief time of cough, expectoration and breathless(The T-value is respectively 16.770, 8.635, 16.762, P<0.05). ②After 7-days treatment, the cure rate of the treatment group was 63.64%, and the control group was 39.39%. Their difference was conspicuous(P<0.05). The total effective rate in treatment group was 96.97%, which was 90.91% in control group. Their difference was inconspicuous(P>0.05).③The pulmonary function indices increased significantly in the treatment group[The values of FEV1、FVC and FEV1/FVC% are (1.41±0.46)L, (2.18±0.63)L and (66.41±6.33)% before treatment, which were (2.21± 0.55)L, (2.83±0.53)L and (77.37±7.64)%after treatment, P<0.01]. A comparison of the two groups showed significant differences regarding the pulmonary function indices(P<0.05). Conclusion Jawei-Wendan decoction had good curative effect in treating acute exacerbation of COPD due to phlegm blocking in lung.

Objective To evaluate the efficiency and safety of Percusurge guardwire distal protection system in coronary intervention in patients with acute myocardial infarction. Methods Three male patients with acute myocardial infarction were enrolled in the study. Primary angioplasty was performed for 2 of them, 2 and 7 hours after onset of the infarction symptom, respectively. Selective angioplasty was performed 17 days after infarction for the third case. Percusurge guardwire system was used during the procedure. Results Procedure success was achieved for all of the 3 cases. Lot of thrombus was sucked out. The infarct-related arteries had TIMI 3 flow at the end of the procedures. The patients′ symptoms were resolved soon after the procedure. Minor dissection was seen in one case which did not obstruct the distal flow and was left alone. Conclusion Percusurge guardwire system can be used safely and effectively in coronary intervention in the thrombus-laden arteries such as acute myocardial infarction.

Objective To summarize the effect and safety of percutaneous coronary intervention (PCI) for CHD in patients with single patent coronary artery. Methods We collected the data of CHD in 10 patients with single patent coronary artery who underwent PCI and analyzed them retrospectively. Results All patients with single patent coronary artery had successful PCI. Symptoms of all the CHD patients had been significantly relieved after PCI. No major adverse cadiac events occurred in hospitalization. Conclusion The data suggest that the patients with single patent coronary artery might be treated with PCI effectively and safely.

Objective To investigate the effectiveness, dose-effect and time-effect relationships for inhibiting neointimal proliferation by 103 Pd radioactive stent, and the safety of the radioactive stent. Methods By angiogaphic, morphometric and histopathologic analysis, we compared 1?000 ?Ci, 500 ?Ci and 100 ?Ci 103 Pd stents with non-radioactive stents on 5 weeks and 12 weeks after stenting in a micro-porcine coronary model of restenosis. Results The neointimal areas of 500 ?Ci and 100 ?Ci 103 Pd stents were significantly smaller than control stents. 1?000 ?Ci stents and control stents had similar neointimal areas. The neointimal areas of 500 ?Ci stents were significantly smaller than 100 ?Ci stents. Compared with control stents, 500 ?Ci stents reduced the neointimal areas by 49% and 50% respectively on 5 weeks and 12 weeks after stenting. Compared with 5 weeks after stenting, the effect of inhibiting neointimal proliferation by 100 ?Ci stents was reduced by 56% (32% vs 14%) on 12 weeks. The neointimal areas on both edge of 100 ?Ci stents were significantly larger than control stents. The neointimal areas on both edge of 1?000 ?Ci stents and 500 ?Ci stents were similar with control stents. No evident radiation damage had been found in the experimental animals who had 103 Pd stent. Conclusion There may be an effective dose window for 103 Pd radioactive stent in inhibiting neointimal proliferation. The effect of inhibiting neointimal proliferation was dose dependent. 103 Pd radioactive stent with appropriate activities may effectively, persistently inhibit neointimal proliferation with no adverse radiation sequelae. These results suggest that 103 Pd radioactive stent prevent restenosis. These data may be useful in predicting safe and effective activity for 103 Pd radioactive stent.
