Objective To obtain the elasticity value of non-mass-like breast lesions with supersonic shear wave elastrography (SWE), in order to observe the value of quantitative elastography with SWE in differential diagnosis of non-mass-like breast lesions. Methods SWE was performed in 80 non-mass-like breast lesions. Taking pathologic results as reference, quantitative elasticity value of the lesions were performed. The diagnostic accuracy, sensitivity and speciifcity were calculated. Results In the 80 non-mass-like breast lesions, 37 lesions (46%) were malignant and 43 lesions (54%) were benign. The max and mean elasticity value of malignant lesions were (106.28±46.39) kPa and (51.02±30.06) kPa, and the max and mean elasticity value of benign lesions were (37.13±18.22) kPa and (26.44±15.62) kPa. There was statistical differences between malignant and benign lesions in max and mean elasticity values (t=15.328, 18.149, both P<0.05). Taking 61.25 kPa as the threshold of max elasticity value and 40.65 kPa as the threshold of mean elasticity value, the diagnostic accuracy, sensitivity and speciifcity were 70.53%, 66.83%, 51.22%and 68.34%, 65.81%, 50.63%, respectively. When max elasticity was combined with conventional ultrasound (US), the diagnostic accuracy, sensitivity and speciifcity were 84.17%, 92.28%and 68.39%, respectively. The diagnostic accuracy and speciifcity signiifcantly increased compared with conventional US (χ2=5.217, 9.652, both P<0.05). When mean elasticity was combined with conventional US, the diagnostic accuracy, sensitivity and speciifcity were 82.35%, 90.66%, and 63.35%, respectively. The diagnostic accuracy and speciifcity signiifcantly increased compared with conventional US (χ2=5.084, 8.686, both P<0.05). Conclusions The diagnostic accuracy and speciifcity of SWE for non-mass-like breast lesions are not high. But when SWE is combined with conventional US, the diagnostic accuracy and speciifcity increase signiifcantly, which is very helpful for the diagnostic of non-mass-like breast lesions.

Objective To investigate the effect of microbubble(Sono Vue) destruction with ultrasound on wound healing in rats. Methods Total 96 SD rats were accepted one rounded whole-layer skin incision on back each other and randomly divided into four groups:microbubble destruction with ultrasound(US + MB),microbubble(MB), ultrasound(US) and control group. Rats in US + MB group were injected with 0.5 ml microbubble contrast agent via tail vein,and then ultrasound irradiated for 3 minutes immediately. MB group were injected with 0.5 ml microbubble contrast agent. US group were injected with 0.5 ml physiological saline,and then ultrasound irradiated for 3 minutes immediately under the same condition. Control group were injected with 0.5 ml physiological saline. Feed each rat in single cage. On day 1,3,5,7,14 and 21 after wound creation,the excised wound tissues were analyzed by histology and VEGF expression in wounds by immunohistochemistry. Results HE staining: On day 7, wounds of US + MB group displayed the most accumulation of granulation tissue and all new capillaries were perpendicular to the wound surface, but the new capillaries of other 3 groups were disordered. Immunohistochemical examination of VEGF expression:the peak expression appeared on day 3 in US + MB group, other 3 groups were on day 5 to day 7.Conclusions US + MB treatment could improve the quality of wound healing and granulation tissues were maturated earlier than MB, US treatment and control group, which could accelerate wound healing. High temperature,high pressure and some kind of chemistry effecs induced by microbubble destruction with ultrasound can stimulate the secretion of endogenous VEGF, which may be the mechanism of promoting angiogenesis and wound healing.

Purpose To assess the initial and follow-up CT findings of proven pulmonary invasive fungal disease (IFD) in patients after hematopoietic stem cell transplantation (HSCT), and to look for the signs for the prognosis. Materials and Methods A retrospective investigation of the CT features and the evolution process was carried out in 13 patients with proven pulmonary IFD diagnosed by histological examination. Results The first abnormal CT finding showed single nodule or mass in 5 cases, two nodules or masses in 2 cases, multiple nodules or masses in 2 cases, patchy consolidation in 1 case, patchy ground glass opacity (GGO) in 1 case, multiple stripes and GGOs in 1 case, and multiple consolidations in peribronchial distribution in 1 case; the presence of reversed halo sign (RHS) was found in 7 cases, not including 4 cases with aspergillosis. The median initial diameter was 32.0 mm, and the median maximum diameter was 51.5 mm. 9 of them reached partial remission after drug treatment, and 9 accepted operation resection. In the end, there were 5 cases cured, 1 keeping stable, 2 suspected recurrent on imaging, and 5 dead. In summary, it showed less than 2 nodules or masses in 7 patients (group 1) and other imaging patterns in 6 patients (group 2), the former group had smaller max diameter (t=4.397, P<0.01), the effective rate within 12 weeks, operation resection rate and final cure rate of group 1 were 85.7%, 100.0% and 71.4%, and those of group 2 were 16.7%, 33.3% and 0, respectively, with group 1 all higher than group 2 (P<0.05). Conclusion Nodule or mass is the most common CT finding of pulmonary IFD in HSCT recipients, with high incidence of reversed halo sign, less than 2 nodules or masses on the first CT imaging may be associated with better prognosis.

Objective To study the role of sodium nitroprusside in preventing pulmonary ische-mia-reperfusion injury and the possible mechanism. Methods Fourteen pigs were randomly divided into 2 groups: control group underwent controlled reperfusion with reperfusion solution (leukocyte-depleting blood modified buckberg perfusate = 4:1) for 10 min at lower pressure of 18 mm Hg and 37℃? 1℃ before removing the pulmonary artery clamp; experimental group were subjected to controlled reperfusion with reperfusion solution before removing the pulmonary artery clamp, followed by infusion of sodium nitroprusside (10?g?kg-1?min 1 for 10 min) via pulmonary artery. Blood oxygen pressure, pulmonary vascular resistance, pulmonary compliance and the changes in pulmonary oxygen-ation function were assessed 0. 5, 1 and 2 h later. After the trail, the contents of water, NO and MDA in pulmonary tissues were measured. Results In the experimental group, left lung oxygenation function and pulmonary compliance was significantly better (P

BACKGROUND:Pain is the main reason for the recovery of knee function after total knee arthroplasty. OBJECTIVE:To explore and analyze the influencing factors of pain after total knee arthroplasty.METHODS:160 patients with knee osteoarthritis underwent total knee arthroplasty. At 12, 24 and 48 hours after total knee arthroplasty, patients were evaluated with visual analogue scale (VAS) and knee function was assessed with KSS score preoperatively and 90 days postoperatively. Factors, including operation time, age, gender, body mass index, anesthesia method, and preoperative score of KSS were analyzed by Pearson correlation and multiple linear regression. These statistics method also was used to analyze the relationship between the postoperative 90 days score of KSS and postoperative VAS score at each time point. RESULTS AND CONCLUSION:(1) Pearson correlation analysis and multiple linear regression analysis showed that operation time, gender, and body mass index had been correlated positively with VAS score at 12, 24 and 48 hours postoperatively. (2) Patient age had been correlated negatively with VAS score at 12, 24 and 48 hours postoperatively. (3) VAS score at 12, 24 and 48 hours postoperatively had been correlated negatively with KSS score at 90 days postoperatively. (4) Gender, operation time, body mass index and age are al the influencing factors of the pain after total knee arthroplasty. Pain after total knee arthroplasty affects the recovery of knee function.
