OBJECTIVE:
To investigate the expression of Angiopoietin-1,2 in laryngeal squamous cell carcinoma (LSCC) and the relationship between Angiopoietin-1,2 expression and clinicopathologic parameters and microvessel density (MVD) marked by CD105, and also evaluate the significance of co-expression of Ang-2 and vascular endothelial cell growth factor (VEGF) in tumor angiogenesis.
METHOD:
The expression of Ang-1,2 and VEGF in samples of tumor, para cancer and normal mucosa were detected by immunohistochemical method.
RESULT:
The expression of Angiopoietin-1,2 were identified in LSCC, para cancer tissue and normal mucosa. The VEGF expression was only existed in LSCC. The expression of Ang-1,2 were significantly higher in LSCC than in para cancer tissue (P < 0.05) and normal mucosa (P < 0.01). In the clinicopathologic parameters, only the expression of Ang-2 was closely correlated with clinical stages and MVD (all P < 0.05). There was no significant correlation between the expression of Ang-1,2 and tumor differentiation degree (all P > 0.05). When the expression of Ang-2 and VEGF were both positive, the mean value of MVD was higher than others (P < 0.05).
CONCLUSION
These results suggest that overexpression of Ang-1,2 may play a very important role in the development of LSCC and are closely correlated with angiogenesis. Ang-2 promote angiogenesis when interacting with VEGF.

About 94. 9%(261/275) and (92. 7%,255/275) of S. pneumonia were resistant to erythromycin and clindamycin. All S. pneumoniae strains were susceptible to teicoplanin, vancomycin, linezolid, tigecycline and daptomycin. Penicillin still showed very high activity against Streptococcus spp. β-Hemolytic group. More than 60% of Streptococcus spp.β-Hemolytic group were resistant to erythromycin, clindamycin and tetracyclines. The prevalence of MRSA and methicillin-resistant coagulase-negative Staphylococci(MRCoNS) was 39. 7%(229/576) and 80. 6%(224/278), respectively. The MRSA prevalence ranged from 24. 2% to 70. 0% in different regions. About 52. 6%( 100/190 ) of Staphylococcus aureus from respiratory tract specimens, 38. 5%(40/104)of Staphylococcus aureus from blood samples, and 29. 7%(58/195) of Staphylococcus aureus from wound and pus were resistant to methicillin. The prevalence of MRSA in elder group ( 48. 6%, 84/173 ) was higher than that in younger adult patients (35. 7%, 144/403)(χ2 =8. 322,P <0. 05). The susceptibility rates of MRSA to chloramphenicol and trimethoprim/sulfamethoxazole were 86. 4% ( 244/228 ) and 94. 7% ( 237/228 ) , respectively. Susceptibility rates to gentamycin, erythromycin, clindamycin, tetracyclines, rifampicin and quinolones were ranged from 15. 8% to 59. 6%. All Staphylococci isolates were susceptible to teicoplanin, vancomycin, linezolid, daptomycin and tigecycline. All Enterococcus isolates were susceptible to daptomycin and tigecycline. All E. faecalis ( 158/158 ) and 96. 4% ( 133/138 ) of E. faecium were susceptible to teicoplanin. About 98. 0% ( 150/153 ) of E. faecalis and 97. 1% ( 145/138 ) of E. faecium were susceptible to linezoild. About 45. 8% (70/153) of E. faecalis and 60. 9% (84/138) of E. faecium were resistant to gentamycin with a high concentration. The susceptibility of E. faecalis to all the antibiotics tested exceptchloramphenicolandtetracyclinewashigherthanthatofE.faecium.Conclusions Basedon different age groups and regions, the resistance rates of Gram-positive cocci are different.

OBJECTIVEThis study investigated the expression of BNIP3 in salivary adenoid cystic carcinoma (SACC) and its correlations to the clinicopathological features and prognosis of patients with SACC. The role of BNIP3 in the progress of hypoxia-induced autophagy was elucidated.
METHODSThe expression levels of BNIP3, hypoxia inducible factor (HIF)-1α, and LC3 in 65 SACC cases were detected by immunohistochemical staining method, and the correlation between the expression of BNIP3 and the clinicopathological features in SACC was analyzed. In addition, the correlations of BNIP3 gene expression with HIF-1α and LC3 gene expression were analyzed. The survival rate of patients with SACC was evaluated by univa-riate survival analysis.
RESULTSBNIP3 was considerably expressed in SACC in all three histological patterns, and was positive in 41 cases (63.1%). BNIP3 gene expression was significantly correlated with histological grade (P=0.001) and HIF-1α gene expression (P=0.011). By contrast, BNIP3 gene expression was not significantly correlated with LC3 gene expression (P= 0.167). The overall survival rate of patients with negative BNIP3 expression was better than that of patients with positive BNIP3 expression (P<0.05).
CONCLUSIONSBNIP3 might play a vital role in the tumorigenesis of SACC and may be a new target for gene therapy. .

Objective:
To investigate the key issues in the diagnosis and treatment of foreign body aspiration in children with tracheobronchial variations.
Methods:
A retrospective study was performed for 11 pediatric patients who were treated in Department of Otorhinolaryngology and Head and Neck Surgery, Henan Province People′s Hospital after a diagnosis of foreign body aspiration with tracheobronchial variations between January 2015 and December 2017. There were 7 males and 4 females among the 11 cases of foreign body aspiration with tracheobronchial variations, ranging between 9 months and 11 years of age.
Results:
Among 11 cases, the types of variationswere tracheal bronchus in 9 cases, bridging bronchus in 1 case and simple tracheal stenosis in 1 case. All of the pediatric patients were under general anesthesia, and the foreign bodies were removed by bronchoscopy successfully with no significant complications.
Conclusions
The possibility of tracheobronchial variations should be considered in children with recurrent wheezing and poor efficacy of regular treatment before foreign body aspiration. Removal of foreign body via rigid bronchoscope under general anesthesia is a safe and effective treatment. These children are needed to combine the situation oftracheobronchial variations and the location of foreign bodies to guide the operation, and strengthened the perioperative treatment.
