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 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.

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

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 distribution of traditional Chinese medical syndrome patterns of dengue fever, thus to standardize its clinical diagnosis and treatment and to enhance its therapeutic effect. Methods A prospective clinical trial was carried out in 210 dengue fever patients who were admitted from July to October of 2014. The clinical data of four physical examinations were collected and analyzed for the analysis of the distribution of syndrome patterns. Results ( 1) The traditional Chinese medical syndromes of 210 dengue fever patients were characterized by fever and aversion to cold, heaviness of limbs, poor appetite, headache and heaviness of head, abdominal fullness and discomfort, yellowish urine, yellowish and greasy fur, sluggish pulse. ( 2) The syndrome patterns of dengue fever were classified into blockage of damp-heat, disease involving both defensive phase and qi phase, heat attacking qi phase, heat attacking blood phase, toxicity invading pericardium, and sudden loss of yang-qi. The incidence of six patterns was in decreasing sequencing. ( 2) The results of laboratory examination showed that the decrease of white blood cell ( WBC) , neutrophil percentage and platelet count was obvious, and the haematocrit ( PLT) became disordered. The results of recheck showed taht the increase of calcitonin and C-reactive protein were not obvious, and the damage of vital organs was less. Conclusion Dengue fever can be classified into the damp-heat pestilence in traditional Chinese medical field. The syndrome patterns of dengue fever are dominated by blockage of damp-heat, and disease involving both defensive phase and qi phase, and correspondingly, the therapeutic methods should be focused on clearing heat, resolving dampness, and strengthening spleen.

Objective To analyze the influences of lacrimal secretion and tear film after interferon-alpha therapy in patients with chronic viral hepatitis.Methods Sixty patients with chronic viral hepatitis who would accept the interferon-alpha therapy,including 30 cases of hepatitis B and 30 chronic viral hepatitis C,visited our department of ophthalmology and were enrolled in this study.All cases received eye examination,including medical history,slit lamp examination,corneal fluorescein staining ( FL) ,tear film break-up time ( BUT) and schirmer test before inter-feron-alpha therapy and two months after the therapy.Results In the 60 cases of chronic viral hepatitis,there were 19 dry eye cases (31.67%) and 41 non-dry eye cases (68.33%).In dry eyes group,9 of them (47.37%) were hepatitis B patients and 10 of them were hepatitis C patients (52.63%) .There was significant difference in FL grade (t=-5.288,P<0.05),BUT (t=5.799,P<0.05),Schirmer Ⅰ(t=5.319,P<0.05) test in hepatitis B before and two months after interferon-alpha therapy.Statistical significance had been found before and two months after therapy in FL grade (t=-9.103,P<0.05),BUT (t=5.682,P<0.05),SchirmerⅠtest (t=4.592,P<0.05). The incidence of dry eye syndrome in hepatitis B patients increased from 26.70%to 53.30%two months after treated with interferon-alpha,while the incidence of dry eye syndrome in hepatitis C patients increased from 33.30% to 60.00% two months after treated with interferon-alpha.Conclusion Dry eye syndrome is one of common complica-tions in patients with chronic viral hepatitis.Interferon-alpha therapy would influence the lacrimal secretion and dam-age tear film,which increased the dry symptoms in patients.We should pay attention to the side effects of interferon-alpha therapy.
