Objective To study clinical features, diagnosis and treatment of allergic bronchopulmonary aspergillosis (ABPA) . Methods Clinical data and auxiliary examinations of eight patients with ABPA were analyzed, as well as relevant literatures were reviewed. Results All patients had symptom of cough, expectoration, out of breath and wheezing tale, seven of them with history of asthma, and all of them had increased peripheral blood eosinophil (EOS) count, serum levels of total immunoglobulin E (IgE) and lgE specific for Aspergillus fumigatus and showed positive prick test specific for Aspergillas fumigatus. Six of them showed infiltration shadows and six of them showed bronchiectasis in their chest CT images. Lung function test indicated obstructive ventilation dysfunction or mixed ventilation dysfunction with reversible airflow obstruction after administration of bronchodilator. Conclusions Diagnosis for ABPA should be made by integration of clinical features, increased blood eosinophil count and serum level of IgE, and result of prick test specific for Aspergillus fumigatus. Corticosteroid is a mainstay therapy for ABPA, ancillary with anti-fungi therapy. Patients with ABPA should be followed-up to prevent its recurrence.

Objective To study the clinical features and angiographic findings of moyamoya disease (MMD) as well as their relationship. Methods A total of 22 MMD patients received routine digital substraction angiography (DSA). The clinical manifestations and angiographic findings were analyzed. Results Clinical manifestations varied and each patient often had multiple symptoms, including cerebral infarction in 9 patients with an average age of 23.6 (13-39 years) and cerebral hemorrhage in 7 patients with an average age of 31.2 (28-46 years). Angiographic examination found that all the diseased sides showed MMD blood vessels. The patients who received encephalo-myo-arterio-synangiosis (EMAS) had better prognosis than those without receiving the treatment. Conclusion Cerebral infarction is frequent in children and adolescents with MMD, whereas cerebral hemorrhage is common in adults. DSA is a golden criterion for diagnosing MMD. Surgical treatment, EMAS blood supply reconstruction in particular, should be prescribed.

Objective To compare the efficacies of intralesional hyaluronidase(HAase), intralesional dexamethasone(DEX), and intralesional HAase plus intralesional DEX on skin damage caused by vinorelbine extravasation in a rat model. Methods After establishing an animal model with vinorelbine extravasation in each lower extremity of 40 Sprague-Dawley rats, we treated the rats with intralesional HAase,intralesional DEX, intralesional HAase plus intralesional DEX,intralesional saline,or received no treatment as control.The wound area on 1 d, 4 d, 8 d, 12 d, 18 d, 24 d, 30 d and the time of healing were observed and compared.Results The wound area on 1 d, 4 d, 8 d, 12 d, 18 d and 24 d was significantly lower in intralesional HAase group, intralesional DEX group,intralesional HAase plus intralesional DEX group,and intralesional saline group than that in control group (P <0.05), and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P <0.05). The healing time was significantly shorter in 4 therapy groups than that in control group [(25.1±3.1) d, (27.9±2.8) d, (23.0±3.2) d, and (28.4±3.9) d vs.(31.2±3.0) d, P <0.05], and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P <0.05). Conclusion The monotherapy with intralesional HAase or intralesional DEX, with decreasing the extent of skin damage and shortening the healing time, is effective therapy for skin damage caused by vinorelbine extravasation, and the monotherapy with intralesional Haase is more efficacious. The efficacy of intralesional HAase plus intralesional DEX seems better than that of monotherapy.

Objective To evaluate the tests in differential diagnosis of subtypes in patients with primary aldosteronism. Methods Fifty-seven patients in the past 7 years chnically diagnosed as primary aldosteronism [22cases of aldosterone-producing adenoma (APA), 26 idiopathic hyperaldosteronism (IHA) and 9 primary adrenal hyperplasia (PAH)] were selected. The plasma potassium, basic and upright plasma renin activity, plasma and urinary aldosterone were determined. 19 patients with essential hypertension served as control. All patients with primary aldosteronism underwent adrenal CT, postural stimuhtion test (PST) and adrenal venous sampling (AVS) to differentiate the subtypes. The clinical and laboratory data were followed up during survey. Results (1) The patients with APA had higher blood pressure and aldosterone level in plasma or urine, but lower plasma potassium and plasma renin activity than those with IHA. In PAH group, these parameters were in the ranges between APA group and IHA group. For the diagnosis of APA, IHA and PAH, the coincidences were 86.4%, 73.1% and 22.2% by adrenal CT, 86.4%, 80.8% and 77.8% by the ratio of aldosterone in both sides of AVS and 95.5%,92.3% and 100.0% by the ratio of aldosterone to cortisol in beth sides, respectively. (2) The plasmaaldosterone, systohc and diastolic blood pressure were decreased after operation in the patients of APA and PAH,and no significant changes were found in patients with IHA. Conclusion The abnormal laboratory findings in patients with APA axe more evident than those in IHA. The result of PST is overlapping considerably in cases ofAPA and IHA. Adrenal venous samphng yields a high coincidence, which should be done in patients with negative CT scanning. The ratio of aldosterone to eortisol in AVS is more reliable. The clinical and laboratory data,especially plasma potassium will be improved after operation in patients with APA and PAH. But there is no change in patients with IHA during the follow-up period.

A sectional survey with histochemical technique was carried out on Culex tritae-niorhynchus larvae infected with Coelomomyces indica in comparison to the noninfected larvae. Studies were pursued by using micrograph and imaging analysis. The results showed that the glycogen, protein and nucleic acid (RNA and DNA)reaction in the infected group were less than those of the control group. The gray level assessment in tissue imaging showed marked difference between the two groups. It is suggested that C. indica has significant effect on the above biochemical elements of the mosquito larvae, which might be considered an important mechanism in the pathogenicity of the fungus.
