ABSTRACT

Objective:To investigate the correlation of central compartment lymph node metastasis(CLNM) in stage T 1a solitary papillary thyroid carcinoma (PTC) with the clinicopathological characteristics, sonographic features and the number of lymph node dissection, and to analyze the risk factors of CLNM. Methods:The data of 218 patients with stage T 1a solitary PTC who underwent thyroid cancer surgery from January 2017 to May 2021 in Tangshan Union Medical College Hospital were retrospectively analyzed. All patients were divided into CLNM positive group and CLNM negative group according to CLNM. The age, gender, preoperative sonographic features, pathological type, the number of lymph node dissection and the number of metastasis were recorded. Logistic regression was used to analyze the risk factors of CLNM. Results:Among 218 patients, there were 71 cases (32.6%) in CLNM positive group and 147 cases (67.4%) in CLNM negative group. There were statistically significant differences in age, tumor diameter, capsular invasion in thyroid or not, tumor blood supply or not, and the number of lymph node dissection between two groups (all P < 0.05). There were no statistically significant differences in gender, clear tumor boundary or not, tumor shape, tumor aspect ratio, calcification, nodular goiter and Hashimoto's thyroiditis or not (all P > 0.05). Multivariate binary logistic regression analysis showed that age < 55 years ( OR = 2.995, 95% CI 1.228-7.307), capsular invasion in thyroid ( OR = 5.297, 95% CI 2.494-11.248) and the number of lymph node dissection ≥6 ( OR = 4.085, 95% CI 2.059-8.104) were independent risk factors of CLNM (all P < 0.05). Conclusions:Patients with stage T 1a solitary PTC, age < 55 years and capsular invasion in thyroid are prone to CLNM; sufficient number of lymph node dissection can get more accurate CLNM rate.

ABSTRACT

Objectives@#To discuss the clinical and radiological features of IgG4-related rhinosinusitis.@*Methods@#In this retrospective research, the clinical data of 16 patients diagnosed with IgG4 related rhinosinusitis, who were enrolled in Beijing Tongren Hospital from November 2013 to September 2017, were collected. The clinical features, laboratory findings, radiological findings, histological features, treatment and prognosis were all summarized.@*Results@#There were 12 males and 4 females among 16 patients, and male-to-female ratio was 3︰1. The age was between 30 to 70 years old, with median age of 52 years old. The chief nasal complaints were nasal obstruction and hyposmia, complicated with proptosis and eyelid swelling in 11 patients (11/16). Serum IgG4 levels were elevated in all patients and the value was over 1.44 g/L, and one patient serum IgG4 level was up to 49.70 g/L. Computed tomography (CT) showed the mainly affected sinuses were bilateral ethmoid sinus and olfactory cleft. The classic feature of CT scans was thickening of the involved bilateral ethmoid sinus mucous membrane with ethmoid bone absorption, which was mainly at midline. Histological features were severe inflammation of the mucosal tissue with mass of neutrophils and plasma cell infiltration. All patients were treated by methylprednisolone combined with cyclophosphamide or methotrexate. Remission of symptoms was detected in all patients.@*Conclusion@#The clinical features of IgG4-related rhinosinusitis are often accompanied by orbital tissue involvement, elevated IgG4 serum concentration, associated sinus imaging changes, and sensitive glucocorticoid and immunosuppressive therapy.

ABSTRACT

Anatomy and surgery teaching has always been a difficulty in clinical medical education. In particular, the anatomy and surgery teaching under the endoscope is more difficult to learn and under-stand because of the visual differences with the direct vision. If the students misunderstand, it may lead to the severe surgical complications. We applied the image-guidance technology in the teaching of rhinology endoscope surgery, which can help teachers to teach the sinonasal anatomical structure and give an accurate explanation of surgical procedures. According to the questionnaire survey, 96.23% (51/53) of the students thought the method was effective and clear, and 98.11% (52/53) of them thought the method was better than the traditional teaching method of nasal endoscope. By this technology, the students can acquire a deeper understanding of the anatomy and surgery procedure. It especially fits the surgery teaching of the sinonasal occupying lesion.

ABSTRACT

OBJECTIVE To analyze the value of modified sinus CT score in olfactory function evaluation before and after functional endoscopic sinus surgery in chronic rhinosinusitis with nasal polyps(CRSwNP). METHODS Fifty-four patients who underwent functional endoscopic sinus surgery for CRS with nasal polyps were enrolled in this prospective study by inclusion criteria and exclusion criteria. T&T methods and olfactory function VAS were used to analyze the subjective olfactory function and were performed preoperatively and at 6 months after surgery. In modified sinus CT score, middle turbinate and superior turbinate associated olfactory cleft areas were used to evaluate the anterior olfactory cleft score(AOCS) and posterior olfactory cleft score(POCS). Sinus CT scans Lund-Mackay scores were also collected before surgery. The correlation between the status of the olfactory cleft on CT, Lund-Mackay score and the preoperative and postoperative olfactory results were investigated.RESULTS Among 54 patients, there were 36 male and 18 female, with average age of 47.9 years old(from 24 to 67 years). There were 30 patients followed 6 months after surgery. The findings of olfactory cleft opacification and the CT Lund-Mackay scores had a positive correlation with preoperative olfactory results(P<0.001). The olfactory cleft opacification showed a stronger correlation with the preoperative olfactory results than the CT Lund-Mackay score. The AOCS was more significantly correlated with the postoperative olfactory results than the other parameters.CONCLUSION Preoperative CT findings, especially the anterior portion of the olfactory cleft had a statistically significant association with the postoperative olfactory results in patients with CRS with nasal polyps.

ABSTRACT

[ABSTRACT]OBJECTIVETo evaluate the curative effect of endoscopic sinus surgery from the viewpoint of biomechanics analysis.METHODSWe select one case undergoing nasal endoscopic surgery for chronic sinusitis patients, after half year follow-up and collect preoperative and postoperative spiral CT data to build a numerical model of nasal cavity and paranasal sinuses with computer numerical simulation (CFD) research methods, to explore nasal airflow distribution and flow field characteristics of value changes before and after the operation. Patients undergo subjective assessments: nasal obstruction of VAS score, olfactory VAS score, SNOT-20, objective assessment: Lund Kennedy score, Lund Mackay score, saccharin test time and acquisition clinical efficacy data to verify the credibility of the analysis method is feasible and the results. RESULTSThe nasal resistance after endoscopic sinus surgery in nasal cavity and paranasal sinuses numerical simulation decreased, middle meatus of nose and nasal air flow velocity decreased, the pressure change slightly;nasal threshold region, middle turbinate head end section in maxillary sinus ostium section, after nearly sieve horizontal cross-section average velocity decreased, nasal airflow for the mucosa of the shear stress reduced. The volume of the nasal cavity and the area of the mucosa was increased, the volume ratio was decreased, the subjective and subjective assessment of the patients was improved, and the objective assessment was lighten.CONCLUSIONAerodynamic rules are presented through the calculation of numerical simulation of fluid mechanics which is invisible before. Better understanding of changes in the nasal airflow distribution and the changes of flow field characteristics can be useful to establish nasal endoscopic surgery in numerical analysis of offshore platform,which provides a new research tool for the understanding of the pathophysiology of chronic sinusitis by endoscopic sinus surgery.

ABSTRACT

[ABSTRACT]OBJECTIVETo compare the aerodynamic differences before and after nasal cavity ventilation expansion techniques in patients with OSAHS. METHODSA total of 30 adult patients with OSAHS were included in this study. Pre-operative upper airway CT of each subject was acquired. Each subject underwent surgery. Postoperative upper airway CT was obtained at least 3 months later. By means of CFD simulation method, numerical simulation was performed to calculate the airflow dynamic indexes of the upper airway. The pre-and post-operative aerodynamic characteristics were compared. RESULTSAfter operation, post-operative negative pressure nephogram of the nasal cavity indicated more smooth variation of pressure gradient, post-operative velocity nephogram of nasal cavity indicated slower airflow velocity. Proper values of flow field indicated the volume of nasal cavity increased significantly (t=4.025,P<0.01), the total nasal airway resistance decreased significantly (t=-2.065,P<0.01). The total negative pressure of the upper airway decreased significantly (t=-2.659,P<0.01) after operation. However, the proper values of flow field increased in 5 patients. CONCLUSIONNasal cavity ventilation expansion effectively increase the volumes of nasal cavity, improve the nasal ventilation, and reduce the air flow velocity of both nasal cavity and pharynx in OSAHS patients, those reduce the pharyngeal negative pressure and the pharyngeal collapse. However, for patients with its narrowest segment at the velopharyngeal level, operation cannot do anything or even aggravate the pharyngeal collapse. Operation should be performed individually.

ABSTRACT

<p><b>BACKGROUND</b>Aberrant epithelial repair has been observed in chronic rhinosinusitis (CRS) patients; however, the mechanism of epithelial cell repair regulation is unclear. Epidermal growth factor (EGF) plays an important role in regulating epithelial cell repair in lower airway and may be a critical factor in the remodeling processes of CRS. The objective of our research is to evaluate the differences between CRS and normal subjects and between chronic rhinosinusitis without nasal polys (CRSsNP) and chronic rhinosinusitis with nasal polys (CRSwNP) in the regulation of EGF pathways and the regulating proliferative position of classic Ras/Raf/MEK/ERK pathways.</p><p><b>METHODS</b>We evaluated the proliferation rates of ethmoidal mucosal cells before and after stimulation with EGF, epidermal growth factor receptor (EGFR) kinase inhibitor AG1478, and extracellular signal-regulated kinase 1/2 (ERK1/2) inhibitor PD98059 using MTT assays. We also analyzed the sinonasal epithelial cells collected from control subjects and patients with CRS subtypes CRSsNP and CRSwNP for the expression of ERK1/2, phosphorylated ERK1/2, P21, P15, and P27 using western blotting analyses.</p><p><b>RESULTS</b>The proliferation rates of sinonasal epithelial cells before and after EGF stimulation were lower in CRS patients than in the controls. AG1478 or PD98059 inhibitor treatment of control epithelial cells did not result in a significant difference in proliferation. Although, AG1478 and PD98059 inhibited the proliferation of CRS cells, the degree of proliferation inhibition was markedly different in CRSsNP. AG1478 suppressed the proliferation of CRSwNP epithelial cells, whereas PD98059 had no effect. The ratio of ERK1/2 phosphorylation in CRS cells was lower than that of the control cells. Cyclin-dependent kinase inhibitors were highly expressed in CRS cells compared with that of control cells. ERK1/2 and P27 showed differential expression in CRSsNP and CRSwNP.</p><p><b>CONCLUSIONS</b>Differences existed in EGF pathways in CRS patients and normal subjects as well as in CRSsNP and CRSwNP. Classical Ras/Raf/MEK/ERK pathway may assume absolute superiority in control cells. Ras/Raf/MEK/ERK classical pathway and other pathways might be active at the same time to stimulate epithelial cell proliferation in CRSsNP. The function of Ras/Raf/MEK/ERK classical pathway was weaker in CRSwNP than in CRSsNP and when the classical pathway was blocked in CRSwNP, some other pathway could have completely compensated the proliferation induced by the Ras/Raf/MEK/ERK pathway.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To examine the effects of continuous and intermittent exercises on obesity and fatty liver in rats fed with high-fat diet.</p><p><b>METHODS</b>Wistar rats were randomly assigned into routine diet (R) and high-fat diet (H) groups, and each group were subdivided into sedentary group (S), continuous exercise (CE) group, and intermittent exercise (IE) group (n=8). In the CE group, the rats were forced to swim continuously for 90 min once daily, and those in the IE group swam for 30 min for 3 times (at a 4-h interval) daily. Both the CE and IE groups exercised for 5 days a week for 8 consecutive weeks. After the experiment, the retroperitoneal, epididymal, and visceral white and brown adipose tissues, the liver, and the gastrocnemius muscle of the rats were weighed. The lipogenesis rate was determined by incorporation of (3)H(2)0 into saponified lipids, and the blood lipid profiles were analyzed. The body weight and food intake of the rats were recorded daily.</p><p><b>RESULTS</b>IE appeared to be more efficient than CE in reducing the adverse effects of high-fat diet and sedentarism. Compared with CE, IE resulted in an improved lipid profile with reduced food intake, body weight gain, visceral and central adiposity, and fatty liver. The effect of high-fat diet and different exercises on weight gain, adiposity, fatty liver, and lipid profile in rats was associated to the manner of exercise, time of each session, age, gender, and length of observation period.</p><p><b>CONCLUSION</b>Intermittent exercise is an important nonpharmacological strategy to control obesity and the related complications.</p>

ABSTRACT

OBJECTIVE@#Analyzing the prognostic factors in endoscopic surgery of juvenile nasopharyngeal angiofibromas (JNA).@*METHOD@#Forty-seven records of JNA, treated with the endoscopic, from 2002 to 2008 were reviewed retrospectively. Previous surgery in other hospitals, sites involved, whether selective embolization was performed before surgery, feeding vessels, operative techniques and follow-up results were recorded. Evaluated factors include previous surgery for resection of JNA, vascular supply from carotid artery, surgery after selective embolization, involvement of cavernous bone in the root of pterygoid process, greater wing of sphenoid bone, interpterygoid fossa, infratemporal fossa and orbit. Chi-square test was used.@*RESULT@#Operations were done under general anesthesia. The follow-up time was 12 to 87 month (median 35 month). During follow up, six patients presented recurrent lesions. Chi-square test showed that deep invasion of the cavernous bone in the root of pterygoid process was related to recurrence (P<0.05). There was no statistically significant difference between other factors and recurrence. Imaging examination showed that recurrent tumor was around the root of pterygoid process.@*CONCLUSION@#Deep invasion of the cavernous bone in the root of pterygoid process which was related to recurrence deserve close attention before and after endoscopic surgery.

ABSTRACT

Objective To establish a molecular technique of internal transcribed spacer (ITS) sequencing to identify pathogenic fungi species from the fungal sinusitis tissues. Methods Total 270 sinusitis tissues samples were collected by endoscopic surgery from 2006 to 2008. The histopathology, organize spring clip culturation and ITS region (ITS region region of fungal rRNA, including ITS1-5. 8S rRNA-ITS2) sequencing were employed simultaneously. And then to evaluate the ITS sequencing as the tool for identification of pathogenic fungi directly from clinical samples. Results Of the 270 samples, histopathology positive rate was 80.0% (216/270) , organize spring clip positive rate was 80.0% (216/ 270), fungal culturation positive rate was 53.0% (143/270) , ITS region sequencing positive rate was 63. 0% [ (134 +28 +8)/270], There were 22 species and 6 genera identified by fungal culturation, and 32 species identified by ITS region sequencing. Conclusion ITS region sequencing will become a applicable tool in clinical laboratory in future.

ABSTRACT

OBJECTIVE@#To evaluate the effect of resection of frontal ethmoid sinus osteomas with nasal endoscopy.@*METHOD@#Eighteen cases of frontal ethmoid sinus osteoma from 2005 to 2008 were enrolled in our study, including 8 cases of frontal sinus osteomas, 6 cases of ethmoid osteomas and 4 cases of frontal sinus osteomas extending to ethmoid sinus. Seventeen cases were treated by an endoscopic approach alone, and one case treated by a combined endoscopic and an external approach.@*RESULT@#All cases were resected completely without complications. The preoperative symptoms disappeared without recurrence within the follow-up periods, ranging from 6 months to 3 years.@*CONCLUSION@#Most frontal ethmoid sinus osteomas can be resected with nasal endoscopy aided by extra nasal incision in some cases.
