Objective To determine in vitro susceptibility of itroconazole,voriconazole,caspofungi,and amphotericin B against 82 clinical strains of filamentous fungi.Methods Etest method was used to test the in vitro susceptibilities of itroconazole,voriconazole,caspofungi,and amphoteriin B against aspergillus fumigatus,A.flavus,A.niger,A.terreus,A.nidulans,et al.Results The MIC range of 4 antifungal agents were 0.03~2.00 mg/L and 0.01~32.00 mg/L against A.fumigatus and A.flavus,respectively.But amphotericin B had higher MIC90 value which was 16mg/L against A.flavus than A.terreus(MIC90 3.00 mg/L),A.fumigatus(MIC90 0.75 mg/L),and A.niger(MIC90 0.25 mg/L).Conclusion Itroconazole,voriconazole,caspofungi,and amphotericin B have different susceptibility patterns against various types of filamentous fungi.It's necessary to identify fungi to level of species and perform antifungal susceptibility test in serious patients.

Objective To investigate the application of electronic bronchoscopy in diagnosis of recurrent tracheoe-sophageal fistula of type Ⅲ esophageal atresia. Methods 5 patients were reviewed who were suspected postopera-tive tracheoesophageal fistula recurrence of type Ⅲ esophageal atresia and examined through electronic bron-choscopy combined with injecting Methylene blue into stomach tube from Jan 2010 to Aug 2014. Male to female ra-tio was 4:1. The age was 2~15 months, median age was 7.4 months. Results The 5 cases were found trachea mem-brane fistula by electronic bronchoscope, recurrent tracheoesophageal fistula was diagnosed with Methylene blue in-jected into stomach tube and overflowed from trachea membrane fistula. Examination time is 3~7 minutes, the aver-age is 4.2 minutes. The 5 cases were confirmed by operation. Conclusion Electronic bronchoscopy combined with injecting Methylene blue into stomach tube to diagnose recurrent tracheoesophageal fistula is safe and feasible, the time is short and the diagnosis rate is high.

Objective To investigate the prenatal diagnosis, perinatal management and standardized treatment protocol for neonates with duodenal obstruction. Methods A network in prenatal diagnosis, perinatal management and monitoring of congenital malformation was founded between Beijing Obstetrics and Gynecology Hospital and the Capital Institute of Pediatrics. Forty-four fetuses were prenatally diagnosed as duodenal obstructions by this network from July,2001 to September, 2010. The data of prenatal diagnosis, treatment after birth and prognosis were analyzed. Results Among 44 patients diagnosed as fetal duodenal obstruction by prenatal ultrasonography, three cases underwent induced abortion, three were in pregnancy, 14 were lost during follow-up and 24 were confirmed by surgical treatments after birth. Within 24 neonates underwent surgery, 21 showed double-bubble sign and 20 combined with polyhydroamnios in prenatal ultrasonography. Twenty-four neonates underwent upright abdominal plain film examination,22 showed double-bubble sign, 1 showed single-bubble sign and 1 showed triple-bubble sign,respectively. Nineteen neonates underwent upper gastroenterography which showed distention of stomach and duodenum, increased stomach peristalsis and an obstacle of duodenum emptying. Within 23 neonates underwent ultrasonographic studies, 10 showed distention and increased peristalsis of duodenum. Following surgical procedures were performed: diamond shape anastomosis was completed in 19 cases with annular pancreas; duodenal vertical resection, across suture and excision of the membrane was done in four cases with duodenum membranate stenosis; end-to-back anastomosis was taken in one case with duodenal separate atresia; Ladd's procedure was applied in 11 cases associated with malrotation. All patients were cured. Conclusions Standardized perinatal management and earlier intervention should be offered to newborns with duodenal obstruction to achieve better effects.

Objective To explore the impacts of WeChat on transitional nursing in patients with coronary heart disease and interventional therapy. Methods A total of 80 coronary heart disease patients received interventional therapy were selected and randomly divided into observation group and control group, with each group 40 cases. The patients of control group were given routine health education, while the patients of observation group were given transitional nursing by WeChat public account and chat group. We compared the results of SAS and SDS, compliance of taking medicine and rehabilitation, and ADL scores between two groups when patients came back hospital for reexamination at three months after discharge. Results At reexamination, the scores of SAS, SDS and ADL in observation group were (42. 50 ± 5. 08), (40. 71 ± 5. 85), (85. 33 ± 11. 12) better than those of the control group (t=2. 342, 2. 593, 2. 456;P=0. 019, 0. 009, 0. 016); the compliance oftaking medication and rehabilitation excises were (17. 69 ± 3. 03), (51. 30 ± 1. 28) which were statistical significant better than scores of the control group (t=2. 325, 3. 028;P=0. 021, 0. 003). Conclusions WeChat has positive impacts on transitional nursing in patients with coronary heart disease and interventional therapy. It can improve patient′s self-care ability, reduce negative emotion, and improve the compliance of taking medicine and physical exercise rehabilitation, which is worthy of promotion.
