[Analysis of the compliance and effectiveness of the allergen specific immunotherapy in patients with allergic rhinitis]

Objective:To investigate the effectiveness and compliance of the 2 year specific immunotherapy in patients with allergic rhinitis. Method:Two hundred and sixty-two patients of allergic rhinitis were treated with SLIT for 2 years. The symptom questionnaire about effectiveness and compliance were obtained 2 years after SLIT. The patient satisfaction was also investigated. Result:Sixty patients had complete compliance and 202 patients had poor compliance. Of the 142 children, 40 (28%) cases had complete compliance, and of the 118 adult patients, 20 cases (17%) had complete compliance. There was obvious difference between the two (P<0.05). Comparing of before and after treatment, total medication score, total nasal symptom score and every symptom score decreased obviously (P<0.05). Two years after treatment, the total effective rate was 63%,there was significant difference between the children group and the adult group (P<0.05). Conclusion:There are a lot of factors affecting the treatment compliance of sublingual immunotherapy, such as patients, family, health care workers and social support, etc. In the course of treatment, a series of strategies can be adopted to improve the treatment compliance. SLIT is an effective method for the treatment of allergic rhinitis, and the treatment effect of children is better.

[One case in which papillary thyroid carcinoma and papillary carcinoma occur on the same side]

thyroid carcinoma is a common tumor in the endocrine system. There are four common types of thyroid carcinoma: papillary carcinoma; follicular cancer; medullary carcinoma; undifferentiated carcinoma. Thyroid papillary carcinoma is derived from follicular epithelial cells, which is different from that of medullary thyroid carcinoma. If both occur in the same side of the thyroid gland, this is very rare. In this paper we report a case in which papillary thyroid carcinoma and papillary carcinoma occurr on the same side.

First Report of Rust of Plumeria rubra Caused by Coleosporium plumeriae in Guangdong Province, China

Plumeria spp. are ornamental trees commonly planted in parks and gardens, and Plumeria rubra cultivars (Frangipani) is most common in Guangdong Province, China. A rust disease of P. rubra was observed on leaves of susceptible plants from August to December 2013. Ten nurseries were surveyed in September 2013, and 91% (220 of 240) of the plumeria plants were infected with rust. Symptoms first appeared as chlorotic spots (about 1 mm in diameter) appearing on adaxial leaf surfaces and then spread to whole leaf, and infection further resulted in leaf necrosis and abscission. Therefore, the ornamental value of diseased trees was greatly diminished. Bright yellow or yellow-orange uredinia were hypophyllous and produced under the epidermis. Urediniospores were catenulate, globose, ovoid or ellipsoid, and sometimes angular in appearance, ranging from 20.0 to 42.0 μm in length by 14.1 to 25.6 μm in width. Their walls were verrucose and 1.3 to 3.2 μm thick. No teliospores were observed. The rust was identified as Coleosporium plumeriae Pat. based on urediniospore morphology (2). Species identity was confirmed with a 1,551-bp sequence (GenBank Accession No. KF879087) of ITS rDNA amplified with rust-specific primers Rust2inv and LR6 (1). The amplicon had a 100% similarity to C. plumeriae (GU145555). Pathogenicity was confirmed by spraying a urediniospores suspension (15,000 spores ml^-1) on five plants of P. rubra cultivar. Five leaves of each plant were inoculated and sealed in plastic bags, while five control plants were applied with sterile water. Plants were held at 28°C for 36 h in a dew chamber. All inoculated leaves developed typical rust symptoms with the uredinia appearing after 9 days, no symptoms developed on any control plants. Urediniospores were produced on infected leaves and pathogen identity was confirmed by morphology and re-sequencing of the ITS rDNA. Plumeria rust was first found in Hong Kong (4) and then in Hainan and Yunnan Provinces, China (3). However, this is the first report of plumeria rust in Guangdong Province, China. Frangipani has large, colorful flowers in the summer, and this rapidly spreading disease causes severe damage and affects their aesthetic value in the second half of the year. References: (1) M. C.

First Report of Bacterial Soft Rot on Tagetes patula Caused by Dickeya dieffenbachiae in China

French marigold (Tagetes patula L.), originally from Mexico, is an annual herb widely planted in China because of its beautiful color, long flowering, and strong adaptability, and has been used widely for ornamentation and decorating. French marigold is also rich in patuletin, quercetagetin, and patulitrin, and is therefore applied medicinally for treating colds and coughs. In early summer 2012, soft rot symptoms on French marigold were found at three flower nurseries in Guangzhou, Guangdong Province, P. R. China, and approximately 25% of the plants had the symptoms. The symptoms included tissue collapse of the stems at the soil line followed by wilting of the whole plants. Within 1 week, the infected stems showed vascular discoloration, turned brown and then inky black, and eventually the whole plant collapsed after the basal stem was infected. Bacteria were successfully isolated from eight symptomatic plants on nutrient agar media incubated at 30°C for 48 h. Ten isolates were selected randomly for further characterization. They were gram negative, degraded pectate, negative for oxidase and positive for indole production, and utilized malonate, glucose, and sucrose but not glucopyranoside, trehalose, or palatinose. Polymerase chain reactions (PCR) were performed using the 16S primers 27f and 1495r (4) for molecular identification. Subsequent DNA sequencing showed that the representative tested strain TP1 (GenBank Accession No. JX575747) was 99% identical to that of Dickeya dieffenbachiae (JF419463) using BLASTn. Further genetic analysis of strain TP1 was performed targeting several housekeeping genes, i.e., dnaX (GenBank Accession No. JX575748) with primers dnaxf and dnaxr (3), gyrB (JX575749) with primers of gyrbf1 and gyrbr1 (1), and gapA (JX575750) with primers of gapa326f and gapa845r (2). They were most homologous to the sequences of D. dieffenbachiae, since they had 97%, 96%, and 97% identity with GenBank accessions GQ904794, JF311653, and GQ891968, respectively. Pathogenicity was confirmed by injecting all 10 original bacterial isolates into each of 10 French marigold seedlings, with approximately 100 μl of a bacterial suspension at 1 × 108 CFU/ml. Ten plants inoculated with 100 μl of sterile water served as controls. Plants were placed in a greenhouse at 30 to 32°C and 90% relative humidity. Within 48 h, soft rot symptoms appeared on all inoculated seedlings, while the control plants appeared normal. D. dieffenbachiae was reisolated from the diseased tissues, and confirmed to be the same as the inoculated pathogen by conducting a 16S rDNA sequence comparison. Previously, black spot, botrytis blight, oedema, powdery mildew, southern bacterial wilt, and damping off have been found on T. patula. To our knowledge, it is the first report of a soft rot caused by D. dieffenbachiae on French marigold. Because of the popularity and high economic value of French marigold, identification of this progressing bacterial disease is important to maintain safe production and beautiful scenery.
