Objective: To investigate the short term clinical efifcacy of endovascular repair for complicated acute type Stanford B aortic dissection.
Methods: To retrospectively analyze the clinical data of 36 patients with complicated acute type Stanford B aortic dissection who received endovascular repair in our hospital from 2010-01 to 2014-06 including operational procedure and post-operative follow-up of CT angiography. There were 27 male and 9 female patients with the average age of 43.7 years (41-62) years.
Results: Successful operations were conducted in all 36 patients. 22 patients received endovascular repair combined with covering left subclavian artery (LSA),10 received endovascular repair combined with chimney technique, 2 received endovascular repair combined with vascular prosthesis bypass from left common carotid artery to LSA, 2 received endovascular repair combined with vascular prosthesis bypass from right common carotid artery to left common carotid artery, whose proximal parts were ligated. Viscera artery and lower extremity artery supply were restored gradually. No complication of endoleak occurred. There 30/36 (83.33%) patients were followed-up for 1 year, and 10 patients developed thrombus in full false lumen and 20 developed thrombus in partial false lumen after 1 year. Compared with pre-operative values, thoracic aortic true lumen volume increased in either thrombus in full false lumen (190 ± 68.7) ml vs, (125.3 ± 63.4) ml and thrombus in partial false lumen (166.2 ± 71.8) ml vs (110.1 ± 62.7) ml,P<0.001; thoracic aortic false lumen volume decreased (65.0 ± 67.4) ml vs (185.3 ± 66.6) ml and (132.3 ± 62.6) ml vs (224.5 ± 72.3) ml,P<0.001. Compared with pre-operative values, for patients with thrombus in full false lumen, the abdominal aortic true lumen volume increased (55.5 ± 12.4) ml vs (48.6 ± 12.2) ml,P<0.01; for patients with thrombus in partial false lumen, the abdominal aortic false lumen volume also increased (58.2 ± 21.5) ml vs (42.5 ± 18.5) ml,P<0.01.
Conclusion: For endovascular repair of complicated aortic dissection, covering LSA with chimney technique and hybrid operation of small incision could extend anchor zone and expand the range of endovascular repair which may improve the effect and reduce the complication for good short term effect.

Objective To investigate the clinical efficacy of bronchoscopic MMC topical spraying for the treatment of tuberculous cicatricial stenosis of the central airway. Methods 45 patients with t tuberculous cicatricial stenosis of the central airway were randomly divided into a control group (14 patients), treatment group 1 (group1, 15 patients), or treatment group 2 (group 2, 16 patients), who received bronchial balloon dilatation alone, bronchial balloon dilatation combined with topical MMC spraying for one time, and for twice, respectively . The clinical efficacy was observed by using the MRC score and measuring airway diameter at the time points before treatment, end of treatment, and 3, 6, and 12 months after treatment, respectively. Results For the MRC scores at different time points, the MRC scores in group 2 (0.06 ± 0.25) and group 1 (0.33 ± 0.617) were significantly lower than those in the control group at 3 months after treatment (P < 0.05 for all comparisons);there were nosignificant differences at the other time points among the three groups. For the airway mean diameters at the different time points, the airway mean diameter was higher in group 2 than in the control group at 3 and 6 months after treatment (P < 0.01), and in group 1 at 3, 6, and 12 months (P < 0.05). No statistical differences were found in the other time points among three groups (P > 0.05). Conclusions Bronchial balloon dilatation combined with topical MMC spraying has certain short-term and long-term efficacy for improving dyspnea and maintaining the airway diameter after dilatation.

PurposeTo evaluate the feasibility and clinical values of CT scan with iterative reconstruction and low radiating dose in craniocerebral trauma.Material and Methods 120 patients suffered from craniocerebral trauma were randomly assigned. All the subjects underwent CT scan using route dose of filtered back projection (FBP) and low dose of iDose (? dose and ? dose), respectively. The quartering were used to subjectively evaluate noise of imaging, skull base artifact, contrast of gyrus-white matter and lesion display in each group. Imaging noise, signal and noise rate (SNR), contrast and noise rate (CNR) of gyrus-white matter and dose length product (DLP) were compared.Results The image quality of both? iDose and ? iDose groups were lower than that of FBP group, but still met the requirement of diagnosis. The image noise of both? iDose and ? iDose groups were higher than that of FBP group (P<0.05). The SNR and CNR of both? iDose and ? iDose groups were lower than those of FBP group (P<0.05). The DLP of both? iDose and ? iDose groups were lower than that of FBP group. There was statistical difference between iDose groups and FBP group (F=2751.46,P<0.05).Conclusion Application of iDose could effectively decrease radiation dose in craniocerebral trauma. Although iDose technique has higher noise level and lower SNR and CNR, the imaging qualities and capability of displaying abnormity meet diagnosis requirement. So that iDose has clinical significance.

Tibial plateau fracture is a common acute trauma of the knee joint. At present, there are many studies on its classification and treatment, and minimally invasive treatment has become a research hotspot and mainstream direction of tibial plateau fracture. We summarized the clinical results of minimally invasive treatment of more than 300 cases of tibial plateau fractures, and proposed the concept of core weight-bearing area on tibial plateau, that is, the core weight-bearing area of the tibial plateau of the knee joint under normal motion statuswhile walking and moderate-intensity running. We performed thinsection CT scanning of the knee joint in a male volunteer for three-dimension finite element modeling.The results showed that during the walking state (the load was twice that of gravity), the core weight-bearing area of the medial and lateral plateaus was 389 mm 2 and 363 mm 2, accounting for 33.2% and 42.9% of tibial plateau, respectively;during the moderate-intensity running state (the load was four times that of gravity), the core weight-bearing area of the medial and lateral plateaus was 418 mm 2 and 406 mm 2, accounting for 35.6% and 48.0%of tibial plateau, respectively. Accordingly, tibial plateau fractures are supposed to be divided into core weight-bearing fracture and non-core weight-bearing fracture, and there are significant differences in the treatment ofthese twokinds of fractures: reduction is more demanding for core weight-bearing fracture,and the fracture involves the core area closely, the anatomical reduction is sought; for non-core weight-bearing area, the reduction requirements can be appropriately low demanded, and even in some cases , for example simple avulsion fracture, marginal fracture, some tibial plateau Hoffa fractures,can be treated conservatively. In summary, during clinical diagnosis and treatmentpractice, orthopedic surgeons should take the core weight-bearing area fracture as the core of diagnosis and treatment, strictly evaluate the extent of fracture involvement, select targeted internal fixation materials, and target to promote more accurate, minimally invasive, and individualized treatment of tibial plateau fractures.

Objective To explore the value of T-SPOT.TB test in diagnosis of tuberculous pleurisy by comparing the T-SPOT.TB test, adenosine deaminase (ADA) of hydrothorax and tuberculosis antibody (TB-Ab). Methods 62 pleural effusion patients are included in the research , of which 32 cases have tuberculosis and 30 cases have no tuberculosis. All patients underwent T-SPOT.TB, pleural effusion ADA, and TB-Ab test. The results were compared with final clinical diagnosis for sensitivity and specificity evaluation. Results The sensitivity of T-SPOT.TB, ADA, TB-Ab were 90.6%, 71.9% and 62.5% respectively. The specificity of T-SPOT. TB, ADA, TB-Ab were 90.0%, 83.3% and 86.7% respectively. The sensitivity of T-SPOT.TB was the highest one among the three methods. The sensitivity of T-SPOT.TB has statistically significant difference compared with TB-Ab (P < 0.05), but no statistically significant difference compared with ADA (P > 0.05). Conclusions The T-SPOT.TB test had higher sensitivity and specificity for the diagnosis of tuberculous pleurisy , and had important reference value in early diagnosis of patients with tuberculous pleurisy. The T-SPOT.TB and TB-Ab combination examination had a complementary effect.
