Objective To explore the effects of Aspergillus fumigatus（A. fumigatus） spores on airway inflammation and responsiveness in asthmatic rats.Methods Seventy male Wistar rats were randomly divided into Ⅰ and Ⅱ groups（n=35 in each group），then Group Ⅰ and Group Ⅱ were subdivided into a normal control group（n=5），an asthma group（n=10），a spores-treated control group（n=10），and a spores-treated asthma group（n=10）.The rats were sensitized to ovalbumin（OVA） and challenged with aerosol OVA to establish the asthma model.The effects of A. fumigatus spores on asthmatic rats before and after OVA aerosol challenging were investigated in Group Ⅰ and Group Ⅱ，respectively.The parameters associated with bronchial epithelial damage were observed by total protein concentration in BALF measured by BCA method.Total and differential cell counts in BALF were also counted.The airway resistance and airway responsiveness were calculated by transpulmonary pressure and gas flow rate.Results In Group Ⅰ，the total protein in BALF in the asthma group treated with A. fumigatus spores before OVA challenging（Group CA） was increased remarkably compared to the asthma group（Group A1）[（1.125±0.254）μg/mL vs（0.825±0.173）μg/mL，Plt;0.01].The nonspecific airway resistances induced by different concentration of acetylcholine in Group CA ［（0.997±0.196）cm H2O•mL-1•s-1，（1.123±0.142）cm H2O•mL-1•s-1，（1.130±0.197）cm H2O•mL-1•s-1］were increased significantly compared to Group A1 [（0.655±0.089）cm H2O•mL-1•s-1，（0.687±0.048）cm H2O•mL-1•s-1，（0.821±0.043）cm H2O•mL-1•s-1]（all Plt;0.05）.In Group Ⅱ，however，the above parameters in the asthma group treated with A. fumigatus spores after OVA challenging（Group AC） were not dramatically increased compared with the asthma group（Group A2）（all Pgt;0.05）.The differences in the total and differential cell counts in BALF in Group CA were not remarkable compared to other subgroups in Group Ⅰ（all Pgt;0.05）.But the BALF neutrophil count in Group AC was increased obviously compared to Group A2 ［（2.488±0.420）×106 vs （0.936±0.459）×106，Plt;0.05］.Conclusion These data indicate that exposure to A. fumigatus spores before challenging causes aggravated epithelial damage and increased airway resistance in an asthma rat model.
Objective To investigate diagnosis and treatment strategies of patients with pulmonary tuberculosis （TB） complicated by Aspergillus infection. Methods Clinical data of 38 patients with pulmonary TB complicated by Aspergillus infection who underwent surgical treatment from January 2008 to December 2010 in Chengdu Infectious Disease Hospital were retrospectively analyzed. There were 23 male patients and 15 female patients with their average age of 37.8 （23-59） years. Preoperatively，all the patients received regular anti-TB treatment for more than 2 weeks，and patients with definite Aspergillus infection received anti-Aspergillus therapy for more than 3 days with consultation of infectious disease physicians. After above treatment，26 patients underwent lobectomy，1 patient underwent right pneumonectomy，and 11 patients underwent left pneumonectomy. All the patients were followed up at the outpatient department after discharge. They were evaluated every 2 weeks in the first 3 months，every 1 month after 3 months，and every 6 months after 1 year. During follow-up，they received acid-fast bacillus smear and sputum culture to check Aspergillus，as well as CT chest scan. Results All the patients successfully received surgical resection of the pulmonary lesion without perioperative death or severe complication. Postoperative pathology examination confirmed pulmonary TB with Aspergillosis infection in all the 38 patients，whose basic diseases included TB cavity in 17 patients，TB-destroyed lung in 12 patients，and post-TB bronchiectasis in 9 patients. All the patients were followed up after discharge for 1.5-4.5 years. During follow-up，they received regular anti-TB therapy for adequate duration in addition to antifungal medications such as voriconazole. None of the 38 patients had recurrence of Aspergillus infection or pulmonary TB. One patient had hemoptysis which was controlled after proper treatment during follow-up. Conclusion Missed diagnosis rate of pulmonary TB complicated by Aspergillus infection is high. Surgical resection of the pulmonary lesion and postoperative medication treatment are the most effective treatment strategies for patients with pulmonary TB complicated by Aspergillus infection.

Methods According to the Cochrane reviewer’s handbook, all the clinical controlled trials involving mycosis fungoides being treated with interferon were retrieved. The Cochrane Collaboration’s software RevMan 5.0.24 was used for meta-analysis. Results Only six papers including 142 patients met the inclusion criteria. Meta-analyses indicated the results as follows: IFN-α monotherapy was more effective than placebo [OR=69.36,95% CI (3.71-1 296.64)] and a traditional Chinese medicine (Di-jing-dan) [OR=35.53,95% CI (1.78-710.56)], but no significant difference was found between INF-α and thymic peptide [OR=15.11, 95% CI (0.71-322.61)], and between IFN-α monotherapy and IFN-α combined with etretinate therapy [OR=3.10, 95% CI (0.79-12.12)]; and there was no significant difference between the efficacy of IFN-γ combined narrowband ultraviolet B (NB-UVB) therapy and that of single NB-UVB therapy [OR=15.00, 95% CI (0.46-485.32)]; Influenza-like side effects occurred to 90% of all the patients, which were usually slight and easy to release. Conclusion Although there are some mild side effects, interferon is safe to treat MF.
ObjectiveTo discuss the possibility and safety of video-assisted thoracoscope surgery for pulmonary aspergilloma. MethodsWe retrospectively analyzed the clinical data of 39 patients with pulmonary aspergilloma in Beijing Chaoyang Hospital between June 2009 and May 2014. The patients were divided into two groups according to their operation method including a conventional thoracotomy surgery group (open group, n=11) and a video-assisted thoracoscope pneumonectomy group (VATS group, n=28). There were 8 male patients and 3 female patients with age of 29-64 (50.7±9.7) years in the open group. There were 13 male patients and 15 female patients with age of 20-75 (55.4±15.3) years in the VATS group. We compared clinical effectiveness between the two groups. ResultsThe operations of all patients were performed successfully. There were statistical differences between the two groups in the average length of operative time (P=0.001), the loss of intraoperative blood (P=0.005), and the score of pain (P=0.001). There was no statistical difference in lead flow of postoperative chest (P>0.05) and the time of hospitalization (P>0.05). ConclusionVideo-assisted thoracoscope surgery in the treatment of pulmonary aspergilloma could be feasible, safe, and effective based on our study. It is worth of clinical application and popularization．
ObjectiveTo explore whether the vaginal environment changes of pregnant women were correlated with pathogenesis of fungal vaginitis. MethodsWe selected 166 women in their early pregnancy in the Obstetrics and Gynaecology Clinic between July 2011 and July 2012 as the study objects (excluding fungal vaginitis patients already confirmed). Two important indicators of changes in pH and the amount of vaginal lactobacilli were chosen to determine changes in the vaginal environment. Using prospective study method, by checking changes in the vaginal environment, the objects were divided into two groups: 96 were in the changing environment group, and 70 were in the normal environment group. Sixty seven of them had a pH value lower or equal to 4.0, and 99 higher than 4.0. Fifty-eight of them had a reduced amount of lactobacillus, and 108 had a normal amount of lactobacillus. The rate of fungal vaginitis in each group was counted. ResultsThe morbidity rate in patients whose pH value was lower than or equal to 4.0 was 17.9% (12/67), while it was 6.1% (6/99) in patients with a pH value higher than 4.0, and the difference was significant (χ2=5.804, P=0.016). The morbidity rate in patients with a reduced amount of lactobacillus was 25.9% (15/58), and it was 2.8% (3/108) in patients with normal lactobacillus, and the difference was also significant (χ2=20.800, P=0.000). The morbidity rate for patients with changing vaginal environment was 16.7% (16/96), and for those with normal environment was 2.9% (2/70), and the difference was significant (χ2=7.985, P=0.005). In those with normal lactobacillus, the reduction of pH value was not correlated with the occurrence of fungal vaginitis (χ2=0.000, P=1.000). ConclusionThe vaginal environment changes during pregnancy (pH value decrease and Lactobacillus decrease) are associated with the incidence of fungal vaginitis, and it can be prevented and treated based on this phenomenon.
