Objective To compare the clinical therapeutic effect of LigaSure vessel sealing system ,ultrasonic scalpel and mo‐nopolar high frequency electrocautery in open thyroid operation .Methods 293 cases of thyroid operation sequentially admitted in our hospital and in accordance with the inclusion criteria were collected and divided into three groups by the method of random dig ‐its table .There were 98 cases in the LigaSure vessel sealing system group (L‐Sure group) ,100 cases in the ultrasonic scalpel (US group) and 95 cases in the monopolar high frequency electrocautery (M‐E group) .The intraoperative and postoperative conditions were compared among 3 groups .Results The operation time ,intraoperative amount of bleeding and postoperative drainage in the L‐S group and the US group were significantly less than those in the M‐E group (P0 .05) .Conclusion The LigaSure vessel sealing system and ultrasonic scalpel can shorten the operation time ,reduce the amount of bleeding and postoperative drainage ,relieve pain and reduce the hospitalization duration .
Résumé
Children allergic rhinitis, referred to as children allergic rhinitis (AR), is a kind of non-infectious inflammation of the nasal mucosa mediated by IgE with the main symtoms of paroxysmal sneezing, rhinorrhoea, nasal itching and nasal obstruction when the susceptible individuals contact the allergen. It is a high reaction disease of the respiratory mucosa common with childhood, which has serious implications to the Children's quality of life, study, rest and growth. The global sampling survey reveals that the morbidity is about 14%, of which 10% in our country and there is an upward trend year by year. At present, drug therapy is still one of the most important methods for children AR. Definite diagnosis, standardized drug therapy and the development of new specific immune therapy make children AR in a good control . This review updates the diagnosis and treatment for children AR, referring to the newest guide by WHO about allergic rhinitis and its impact on asthma (ARIA).

OBJECTIVE@#To establish a biofilm model of Haemophilus influenzae and observe the effect of ambroxol on biofilm of Haemophilus influenzae and bactericidal action.@*METHOD@#Thirty strains of Haemophilus influenzae were isolated from adenoids of children with adenoidal hypertrophy. Two strains which could build stronger biofilms was selected in a 96-well plate. The effect of ambroxol on biofilms were determined by crystal violet, and the structure of biofilms were observed by scanning electron microscope (SEM). The numbers of viable bacterial in biofilm after ambroxol treatmented determined by plate culture count.@*RESULT@#Through crystal violet assay, significant difference (P < 0.01) between the two group after treatment was found when ambroxol concentration reached at 0.25 mg/ml and 0.49 mg/ml. The biofilms was destroyed by SEM. Ambroxol had the positive effect on bacterial killing by plate culture count,and the effect was in a dose dependent.@*CONCLUSION@#Ambroxol could destroy the biofilm of Haemophilus influenzae, and had bactericidal function in vitro.
