Objective:To establish the HPLC fingerprint of Cassia leschenaultiana from different regions. Methods: The column was SinoChrom ODS-BP (250 mm × 4. 6 mm, 5 μm). The mobile phase consisted of acetonitrile-0. 1% phosphoric acid with gradient elution. The flow rate was 1. 0 ml·min-1 , the detection wavelength was 285 nm, the column temperature was 25℃, and the injection volume was 10 μl. Results: The fingerprint consisted of 13 common peaks. The range of similarity for ten batches of Cassia le-schenaultiana was 0. 839-0. 998. And the reference fingerprint of Cassia leschenaultiana was established by HPLC. Conclusion: The fingerprint method is simple and reproducible, which can provide basis for the quality control and the medicinal resources exploration.

Objective To study the causes and clinical features associated with hoarseness in children.Meth-ods The data of 4 668 children suffering from hoarseness were analyzed with electronic-nasopharyngolaryngosco-py retrospectively.ResuIts The top 6 common causes of hoarseness were chronic laryngitis (1 817 cases,38.9%), vocal cord nodules (1 494 cases,32.0%),vocal hypertrophy (560 cases,12.0%),the paralysis of vocal cord (373 cases,8.0%),congenital sulcus vocalis (149 cases,3.2%)and recurrent respiratory papilloma disease (140 cases,3. 0%).These six diseases were common in children with hoarseness with 4 533 out of 4668 (97.1%);of the chil-dren were 2 to 10 years old as the largest age group (65.8%,3 072/4 668)and the ratio of male and female was 2. 48:1.The top six diseases were statistically distributed in different age groups (P<0.01).ConcIusion The main causes of hoarseness were different in different age groups.The children aged 2 to 10 years old made up the largest group (3 072/4 668),showing the greatest incidence of hoarseness in children .The incidence for male patients was higher than female and the chronic laryngitis was the top disease.Hoarseness in children was different from that of adults so that to understand the characteristics of this disorder in children will be beneficial to the proper diagnosis and effective treatment.

OBJECTIVE:
To classify congenital laryngeal cysts in 62 newborn or infants, and to discuss the characteristics of different operation mode.
METHOD:
The clinical data of 62 infants with laryngeal cysts treated were reviewed retrospectively. After the examination of neck palpation, laryngoscope and imaging (CT or MRI), all patients were under general anesthesia of laryngeal cyst excision. we select operation mode according to the classification. Classification include: 61 cases of cysts were confined to the larynx, 1 case was beyond the larynx. Surgical managements include: an excision through external carotid approach in 1 case beyond the larynx, 61 cases had endoscopic excision under general anesthesia (12 cases with traditional bite exception, 12 cases with powered system and 37 cases with low-temperature radiofrequency ablation).
RESULT:
The operations was successful. No recurrence was found after 0.5 to 7 years follow-up.
CONCLUSION
To chose surgical management after classification and preoperative assessment, which could avoid unnecessary opening surgical approaches, reducing the recurrence, and preventing repeated endoscopic treatment or tracheotomy. The low-temperature radiofrequency ablation had the advantages of short operation time, less bleeding, little injury, low recurrence rate and light postoperative reaction. It is worthy of clinical promotion.

OBJECTIVE:
To explore the clinical characteristics and treatment skills of children with respiratory special foreign body.
METHOD:
To retrospectively analyze the clinical characteristics of 49 cases of special airway foreign bodies in children during 2013. 5.1-2014. 5.1 in our hospital, and the treatment methods were summarized.
RESULT:
Fourty-seven cases with rigid bronchoscopy foreign body cured, 1 case turned Department of thoracic sur- gery chest to remove foreign body, 1 case of death.
CONCLUSION
The clinical characteristics of special airway foreign bodies in children is different from ordinary foreign body, treatment of preoperative, intraoperative and postoperative is not fully equivalent to the ordinary foreign body.

OBJECTIVE:
To describe and analyze the clinical characteristics of nasopharyngeal teratoma in infants and improve the levels of diagnosis and treatment to reduce misdiagnosis.
METHOD:
The clinical data of 11 cases of nasopharyngeal teratoma in infants were reviewed retrospectively and summarized the clinical features. After the preoperative examination of nasopharyngeal endoscopy and imaging (CT or MRI), all patients were under general anesthesia of nasopharyngeal teratoma surgical resection. Of them, 8 cases were used radiofrequency ablation, 3 cases used conventional power systems.
RESULT:
Eleven cases with neoformation were completely removed, the operation time was 5-15 min, blood loss was 1-5 ml, patients had no significant nasal obstruction, bleeding, eating nasopharyngeal regurgitation, breathing difficulties or other complications. No recurrence was found after 10 months to 9 years followed up.
CONCLUSION
The nasopharyngeal mass must be kept in mind in the differential diagnosis of breathing difficulties in infants, especially when it exists together with upper airway obstruction symptoms; The low-temperature radiofrequency ablation with endoscopic had the advantages of short time, precise control, less bleeding, clear operative field, little injury and pain, low recurrence, providing a new clinical treatments.

Objective:To observe the effect of Livostin spray on children's allergic rhinitis and to search the mechanism of treating allergic rhinitis. Method: 113 patients were treated with Livostin spray (Livostin group) or normal saline spray (control group). Result:The total efficiency of Livostin group in treating allergic rhinitis is above 95.1% and that of the control group is 25.0%. Initial time of starting effect of Livostin (72.1%) is in 1 minute, and that of the control group (mostly 23.1%) is in 3 minutes. The keeping curativeeffect time of Livostin spray is mostly (72.1%) above 5 hours and that of the control group is mostly (30.8%) in 3 hours. After 2 weeks,the eosinophilic granulocyte number in nose's secretion of Livostin group is obviously reduced (P<0.05). Conclusion: Livostin is better than control group in relieving symptoms, keeping curative effect and safety,so Livostin is one kind of effective drug in treating children's allergic rhinitis.
