Objective: To study the expression of TNF\|α and CD68 in nasal polyps tissue and their significance. Methods. Paraffin sections of 19 nasal polyps and 8 chronic rhinitis samples were studied with immunohistochemical technique. Results. The expression of TNF\|α were stronger in nasal polyps tissues than that in controls. Numerous CD68 positive cells were found in epithelium laryer and in the lamina propria of nasal polyps. There were positive relationship between the expression of TNF\|α and that of CD68(r=0.615). Conclusion. It was suggested that activized macrophage as antigen\|presenting cell in the development of nasal polyps, may play a important role through upregulated TNF\|α′s synthesis and secretion.

OBJECTIVE: To evaluate the efficacy and safety of a short course of nebulized budesonide via transnasal inhalation in chronic rhinosinusitis with nasal polyps. METHOD: Fifty patients with severe eosinophilic nasal polyps were randomized devided into study group (n = 25) and control group (n = 25). The study group received budesonide inhalation suspension (1 mg twice daily) via transnasal nebulization for one week and the control group received oral prednisone (24 mg QD). Visual analogue scales (VAS) of nasal symptoms, endoscopic polyp scores (kennedy scores) and morning serum cortisol concentrations were assessed in both groups pre- and post-treatment. Operation time and surgical field bleeding were evaluated. RESULT: Four subjects dropped out in control group. Budesonide transnasal nebulization caused a significant improvement in all nasal symptoms especially nasal obstruction (baseline: 8.25 ± 0.53; after treatment: 4.97 ± 0.97, P < 0.01) and reduced polyp size significantly (baseline: 4.64 ± 0.63; after treatment: 3.40 ± 0.76, P < 0.01) compared to pre-treatment. The patients treated with oral prednisone, however, showed more obvious improvement in nasal symptoms and polyp size, shorter operation time and better surgical field than budesonide group. Additionally, the morning serum cortisol concentration was mildly decreased after one week treatment in budesonide group [baseline (17.18 ± 2.83) μg/dl, after treatment (16.24 ± 2.93) μg/dl, P > 0.05], but all values were still located in normal range (normal range: 5-25 μg/dl). Conversely, the morning serum cortisol concentration in oral prednisone group was lower than normal limit [baseline (18.19 ± 2.81) μg/dl, after treatment (2.26 ± 0.70) μg/dl, P < 0.01]. CONCLUSION Twice daily budesonide transnasal nebulization is an effective and safe treatment as evidenced by significant improvements in nasal symptoms and reduction in polyp size, coupled with an absence of hypothalamic-pituitary-adrenal axis suppression, which is safer than the systemic corticosteroids. Budesonide transnasal nebulization offers a viable treatment option for CRSwNP before operation.

Sinonasal inverted papilloma (SNIP) is one of the most common benign sinonasal tumors demonstrating a high recurrence rate after surgery, and sometimes presents malignant tendency or coexists squamous cell carcinoma. Therefore, it is essential to achieve complete surgical resection, especially the original location of SNIP. In this paper, we evaluated the predictability of preoperative CT and magnetic resonance imaging (MRI) for localization of SNIP origin.

[ABSTRACT]OBJECTIVETo observe the anatomic relationship between the middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus. METHODS206 cases of sinus CT without maxillary disorders were enrolled. The middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus is divided into fusion type and separation types, and the angle between the anterior and medial wall of the maxillary sinus is divided into frontal and lateral types in relation to the middle and distal section of bony lacrimal duct.RESULTSThe fusion type accounted for 40.05%, and the separate type was 59.95%. There was no statistical difference between male and female.The proportion of inconsistency on both sides was 16.02%. The frontal type of the angle between the anterior and medial wall of the maxillary sinus accounted for 64.08%, meanwhile the proportion of the lateral type was 35.92%. The lateral type was 84.24% out of the cases of fusion type, whereas the frontal type was15.76%. In the separate type, the frontal type accounted for 97.17%, and the lateral type was 2.92%. CONCLUSIONThe anatomic relationship between the middle and distal section of bony nasolacrimal duct and anterior wall of maxillary sinus shows different type, which is helpful to choose operative strategy.

OBJECTIVE: To explore the expression and significance of programmed cell death 5 (PDCD5) and Bcelllymphoma/lewkmia-2(Bcl-2) in sinonasal squamous cell carcinoma (SNSCC). METHOD: Immunohistochemical method and Western Blot method was used to determine the expression of PDCD5 and Bcl-2 in specimen of SNSCC in thirty cases, sinonasal inverted papillomas (SNIP) in thirty-eight cases, and normal nasal mucosa in twenty cases. RESULT: (1) The expression of PDCD5 protein in SNSCC significantly decreased compared with SNIP and normal nasal mucosa. (2) The expression of Bcl-2 protein in SNSCC up-regulated obviously compared with SNIP and normal nasal mucosa. (3) Positive rate of PDCD5 protein and Bcl-2 protein in well, moderate and low differentiatied group is respectively 100.00%, 83.33%, 38.89% and 50.00%, 70.83% and 100.00%, the difference was statistically significant (P < 0.05). (4) In the follow-up cases, the survival rate of the patients with higher expression of PDCD5 protein was higher, but that with lower expression of Bcl-2 protein was higher. CONCLUSION The inactivation of PDCD5 protein and the activation of Bcl-2 protein may play an important role in the development of SNSCC, and there are a positive correlation between PDCD5 and Bcl-2 protein in SNSCC, which may be identified as a new therapeutic target.

OBJECTIVE To evaluate the clinical outcome of submucosal inferior turbinectomy and outfracture surgery of inferior turbinates. METHODS All patients receiving two different operations were measured by acoustic rhinometry and questionnaire of QOL at preoperative 1 week and postoperative 12 months, seperately. RESULTS Forty-seven patients with inferior turbinate hypertrophy were enrolled in this study. Evaluation of SNOT-20 discovered both surgeries could improve patients' QOL with similar outcome. Preoperative '5 important items' in patients with inferior turbinate hypertrophy were 'lack of a good night's sleep', 'need to blow nose', 'thick nasal discharge', 'fatigue' and 'dizziness'. Postperative '5 important items' were 'postnasal discharge', 'runny nose', 'sneezing', 'reduced concentration' and 'reduced productivity'. Both surgeries could make acoustic rhinometry parameters change obviously, such as minimal cross-sectional area, 0-5 cm nasal volume(NV) and 2-5 cm NV. Furthermore, submucosal inferior turbinectomy produced more volume in nasal cavity than outfacture surgery, (7.28±2.01)cm3 vs (6.01±1.22)cm3, (5.99±1.87)cm3 vs (4.23±1.08)cm3(P<0.05), seperately. There was no correlation between the data of SNOT-20 and acoustic rhinometry. CONCLUSION We recommend outfracture surgery of inferior turbinate as the preferred surgical choice for patients with mild inferior turbinate hypertrophy.

Objective:To evaluate the CT characteristics of ossifying foci in sinonasal inverted papilloma (IP) and to compare with the tumor root shown intraoperatively.Methods:The clinical and CT imaging data of 127 patients with IP, which were proved by histopathology, were reviewed retrospectively from Beijing Tongren Hospital, Capital Medical University, during the period from January 2012 to December 2018. The number, location, shape, density of ossifying foci in sinonasal IP and the relationship with the wall of sinus were observed. The sites of ossification on CT scans were compared with the root of the tumors described in the corresponding patient′s operative records.Results:In 127 IP patients, 51 (40.2%) patients showed the ossification in the tumor on CT. Single ossifying foci were found in 35 cases and multiple in 16 cases. The ossification affected single site of the sinonasal tract ( n=16) or distributed diffusely ( n=35). In the 50 cases, the ossifying foci extended along the long axis of the affected sinus appearing as branched ( n=19), striped ( n=16), linear ( n=7), lumpy ( n=2) or mixed type ( n=6), and 1 case was located at the edge of the maxillary sinus. Totally 66.7% (34/51) of the ossifying focis contained peripherally hyperdense bone tissue and centrally hypodense adipose tissue, which corresponded to bone cortices and fatty marrow of the trabecular bone. And 96.1% (49/51) of the ossifying focis were attached to the adjacent bone of the sinus, and the sites of attachment were concordant with the actual origin of tumor confirmed in operation . Conclusions:Ossification can be seen in some sinonasal IPs. Tracing along ossifying focus to the site of attachment with sinus might facilitate preoperative prediction of the originating site of tumor.

Objective To explore the influence of abnormal donor hepatic artery on hepatic artery and biliary complications after liver transplanta?tion,and summarize the hepatic artery reconstruction procedures during transplantation. Methods The clinical data of 210 cases of liver transplan?tation conducted in our hospital from May 2005 to April 2015 were retrospectively searched for the study,including 42 with abnormal donor hepatic artery. Results Among the 210 liver transplantation,42 cases exhibited abnormal donor hepatic artery,and the aberration rate was 20.0%. Mean volume of blood flow of abnormal group and normal group was 4.7±95.1 mL/min and 190.9±101.6 mL/min,respectively. There was no statistic differ?ence(P=0.519). Twelve cases had arterial complications,the incidence rate was 5.71%,and there was no statistic difference between each group (χ2=0.72,P>0.05). Twenty five cases got biliary complications,the incidence rate was 11.9%,and there was no statistic differences between each group(χ2=0.05,P>0.05). Conclusion There was no statistic difference of mean volume of blood flow after arterial reconstruction between two groups. Liver transplantation with abnormal arterial reconstruction will not increase the incidence rate of arterial and biliary complications.
