OBJECTIVE To investigate the opportunity and method of surgery for removing tracheobronchial foreign bodies. METHODS A retrospective study was carried out among 500 children with tracheobronchial foreign bodies treated in our hospital from June, 2005 to June, 2009. RESULTS The foreign bodies were successfully removed in 4(0.8%) patients with fiberoptic-bronchoscopy, 2(0.4%) patients with thoracotomy, 20(4%)patients with endoscope or rigid bronchoscopy via tracheostomy, 32(6.4%) patients with direct laryngoscopy, 436(87.2%)patients with rigid bronchoscopy . There were 6 patients (1.2%) need another operation to fully remove the foreign bodies. CONCLUSION Proper method should be choose for removing tracheobronchial foreign bodies according to the history, location and kind of the foreign bodies.

Result :Of all thepatients underwent surgery, 14 cases were free from disease postoperatively within 0.5 years follow-up, 2patients underwent re-operation because of recurrence. Conclusion:Knowing about the disease fully, selectingproper surgical incision and possessing skilled surgical technique is important to improve the level of diagnosisand treatment about the first branchial fistula.

Objective:To investigate the clinicopathlogical significance of the CyclinE,p21WAF1/CIP1 and p53 expression in laryngeal carcinogenesis.Method:The expression of CyclinE,p21WAF1/CIP1 and p53 was examined by using immunohistochemical method in normal epithlia (20),dysplastic epithlia (40) and laryngeal cancers (60).Result:①In normal epithlium,dysplastic squamous epithlium and in squamous cell carcinoma of the larynx,the positive immunostaining rate of CyclinE protein was 5.0%(1/20),20.0%(8/40) and 45.0%(27/60) respectively (P＜0.001),and p21WAF1/CIP1 protein was 95.0%(19/20)，75.0%(30/40) and 63.3%(38/60) respectively (P＜0.01),while the rate of p53 was 0,30.0%(12/40) and 61.7%(37/60)(P＜0.001) respectively.②p21WAF1/CIP1 positive expression in highly、moderately and poorly differtiated carcinomas were 76.2%(16/21)、66.5%(19/29) and 30.0%(3/10) respectively (P＜0.05),p21WAF1/CIP1 protein expression was significantly associated with tumour cell differentiation.③The positive expression of CyclinE closely related with the positive expression of p53 (P＜0.05).No correlation was found between p21WAF1/CIP1 expression and p53 expression.Conclusion:①CyclinE and p53 could be an early molecular event in the carcinogenesis of larynx.②p21WAF1/CIP1 expression is associated with tumour cell differentiation.③The mutual mechenism of cell cycle regulators (CyclinE、p21WAF1/CIP1 and p53) play an important role in the laryngeal carcinoma.

The paper describes the significance of clinical pathological congresses in clinical work. It argues that at present there is the tendency of laying stress on modern advanced diagnostic means at the expense of basic physical diagnostic means and traditional therapies, and traditional conduction of clinical pathological congresses for the purpose of summarizing medical experience and promoting medical advancement has even become a rarity, which is very harmful to the cultivation of qualified clinical doctors. The paper gives an account of how the authors' hospital encouraged performance of autopsies and persisted in holding clinical pathological congresses. Its experience is that clinical pathological congresses have many functions in clinical work, including solving knotty problems like multidisciplinary and multisystematic pathological changes by drawing upon all useful opinions; exchanging information, which is beneficial to doctors learning from one another and making common progress; cultivating personnel via tempering young doctors and updating senior doctors'knowledge; and strengthening the hospital's cohesive force.

OBJECTIVE: To evaluate the clinical effect of acellular dermal matrix (ADM) on the repair of different tissue defects in pharyngeal and laryngeal cancer. METHOD: Twenty-three cases of pharyngeal and laryngeal cancer were analyzed retrospectively, including 16 patients with pharyngeal cancer, and 7 patients with laryngeal cancer. After surgery, the patients appeared two types of tissue defects respectively: hypopharynx tissue defect and neck skin tissue defect. These defects were repaired with ADM, and the clinical effects were observed. RESULT: Sixteen cases of hypopharynx tissue defect and 7 cases of neck skin tissue defect were repaired with ADM. One case in hypopharynx tissue defect group and 2 cases in neck skin tissue defect group undergone pharyngeal fistula postoperatively. CONCLUSION The repair of tissue defects in pharyngeal and laryngeal cancer with ADM had some advantages, such as good histocompatibility, low immune rejection, wide material sources and simple method. There were some differences in clinical effects between hypopharynx cavity defect and neck skin tissue defects, so the emphasis of the need to pay attention to is different in the clinical.

OBJECTIVE: To compare the clinical results between stapled and traditional suture closure total laryngectomy. METHOD: Fifty-three cases of laryngeal cancer with total laryngectomy were divided into 2 groups: 32 cases with traditional suture closure total laryngectomy (group A) and 21 cases with stapled total laryngectomy group (group B). Compare two groups in pharyngeal fistula, postoperative bleeding, dysphagia, and nasal regurgitation. RESULT: There was no difference of postoperative pharyngeal fistula between group A and B (P>0. 05). The incidence of dysphagia, nasal regurgitation, and postoperative bleeding in group B were 23. 8%, 14. 3% and 14. 3% respectively, which were obviously higher than that in group A (P<0. 05). CONCLUSION Stapled total laryngectomy has the advantages of reducing the operative time and simplifying the operation with some disadvantages such as higher standards of operation indications, higher incidence of dysphagia, higher nasal regurgitation, higher postoperative bleeding, and poor medical economic profit. Traditional suture closure total laryngectomy is recommended in clinical practice.

Objective To provide a reliable differential diagnosis among the progressive supranuclear palsy ( PSP), striatonigral degeneration ( SND ) and Parkinson disease ( PD ) . Methods Conventional MRI data in clinically proved PSP(8 cases), SND(9 cases), PI)( 12 cases)and 12 normal controls were retrospectively analyzed. Midbrain area, pons area, ports diameter and middle eerebellar peduncles width were measured. The ratio of pons area over midbrain area (pons area/midbrain area) was calculated in all patients and normal controls. Then one way ANOVA and a Kruskal-Wallis H test were used for statistical analysis. Results Midbrain area of the PSP group [ (85. 8±12. 0) mm2 ] was the smallest, and there was statistically significant difference ( P < 0. 05 ) comparing with the SND group [ ( 133.2± 8. 4) nun2 ], PD group[ ( 133. 5±10. 8) mm2 ] and the control group [ ( 135.9±7.5 ) mm2 ]. There was no overlapping in the distribution of midbrain area between the PSP group(66.0-98. 2 mm2 ) and SND, PD and normal groups( 116. 2-142. 1, 110. 8-146. 2 and 121.7-145.8 mm2 ). The pons area-midbrain area ratio (P/M) of the PSP group (5.9±0. 8) was the largest in four groups, and there was statistically significant difference ( P < 0. 05 ) comparing with the SN D group ( 2. 9±0. 5 ), PD group ( 3.8±0. 3 ) and the control group (3. 8±0. 3 ). There was no overlapping in the distribution of P/M between the PSP group(5.0-7.2) and SND,PD and normal groups(2. 2-3.5, 3. 3-4. 6 and 3. 2-4. 2). SND group had the smallest P/M, pens area, pons diameter and middle cerebellar peduncles width [ 2.9±0. 5, ( 384. 8±62. 6) mm2 , ( 18. 6±2. 0) nun and( 12. 9±2. 4) mm ] in all groups, and significant difference ( P < 0. 05 ) was found comparing with the PSP group[5.9±0. 8, (500.1±21.8)mm2, (22. 7±1.7)mm and( 16. 3±1. 1) nun],PD group[3.8±0.3, (500.2±25.8)mm2, (23.7±1.0)mm and(16.8±1. 1)mm]and the control group [3. 8±0. 3, ( 508. 8±20. 6 ) mm2, ( 23.2±1.2) nun and ( 16. 4±0. 9 ) mm]. But the PD group and control group had no statistically significant difference in the midbrain area, pans area, pons diameter, P/M and middle cerebellar peduncles width ( P > 0. 05 ). Conclusion MRI measurements helps in the differential diagnosis among PSP, SND and PD.

Objective To localize the upper airway obstruction of patients with obstructive sleep apnea hypopnea syndrome (OSAHS)with the Cinema Magnetic Resonance(Cine-MR) and fiber optic laryngoscope with Müller maneuver(FLMM)before operation and discuss the clinical application values.Methods Before operation, FLMM and Cine-MR were applied to 22 patients diagnosed as OSAHS by Polysomnography(PSG).Medical examinations conducted in this study from September 2015 to April 2016 to examine the obstruction of the soft palate region, the lingual region and epiglottis.Results There were complete agreements between the Cine-MR and FLMM at locating obstruction sites of the soft palate (n=22/n=22),and there were moderate agreements between the Cine-MR and FLMM in locating obstruction sites of the retroglottal region(n=13/n=6),epiglottal region (n=4/n=2)and multiple level(n=13/n=6), respectively.Conclusion For those moderate and severe OSAHS patients with multiple sites obstruction , the preoperative application of the Cine-MR and FLMM together will be better in locating the obstruction sites.
