Nasopharyngeal cancer is a low differentiated squamous cell carcinoma, and the radiation therapy is the primary choice. It's 5 year survival rate may reach 64.4%, while 10.0% cases may suffer from the local recurrence. The salvage radiation or surgery is still the main choice for recurrent cases now. However the recurrent tumor become radiation insensitive and meanwhile, morbidity and mortality become higher. The experience of open salvage surgery on the recurrent radiation insensitive tumor had been proved safely, and the related morbidity and mortality are acceptable. Recently, the endoscopic salvage surgery has been developed, some preliminary experience has been obtained and the result looks promising. In this article, the pathobiological characteristics of the postradiation local recurrent nasopharyngeal cancer, the anatomy of nasopharyngus and related skull base area, especially the petroclival region and current situation of endonasal endoscopic salvage surgery were reviewed here. Basic principle of oncological surgery that endoscopic surgery should followed and possible endoscopic surgical approaches were proposed.

OBJECTIVE: To compare the results of skin prick test with allergens of Allergopharma company or ALK company in Shanghai area. METHOD: The study included 9 233 patients diagnosed as allergic rhinitis. The patients were divided in to two groups (Allergopharma group and Alutard-SQ group) SPT was given from June, 2005 to Feb, 2013. The results of the positive rate using two reagents were analyzed and compared. RESULT: There were no significant differences between the two groups in age and gender (P > 0.05). The total positive rate in Allergopharma group was 62.90%, and 59.68% in Alutard-SQ group. The positive rate in Allergopharma group was significantly higher than that in Alutard-SQ group (P < 0.01). Dermatophagoides farinae (Der f) and Dermatophagoides pteronyssinus (Der p) were identified as the mostly responsible allergens. The positive rate of Der f in Allergopharma group and Alutard-SQ group was 55.23% and 45.57% respectively. The same rate were 54.83% and 47.89% of Der p. There were significant differences of the positive rate of two allergens in both groups (P < 0.01). CONCLUSION The total positive rate was different using different allergens for SPT among the patients diagnosed as allergic rhinitis of the same area. Dust mites were identified as main allergens. The positive rate was different when using different reagents, which needed more attention to make the decision of specific immune therapy.

Objective：To study anatomic basis of ligaments factors in carpal radial instability. Methods:The length, width, thickness and maximum length of radial scaphoid capitate ligament(RSCL) , radial lunate ligament(RLL) , radial scaphoid lunate ligament(RSLL),radial scaphoid ligament(RSL), scaphoid trapezium ligament(STmL), scaphoid lunate interosseous ligament(SLIL), scaphoid triangular ligament(STgL) and radial ulnar triangular ligament(RUTgL)were measured in the neutral position. The length of RSCL, RLL, RSLL, RSL and RUTgL in the maximum position of radial deviation, ulnardeviation, palmarflexes and dorsiflexes were also measured. The normal and maximal distance of scaphoid lunate gap(SLG) , scaphoid trapezium gap(STmG), radial scaphoid gap(RSG) and capitate lunate gap(CLG) were measured,especially for variation of SLG in the condition of different ligament lesions. Results:Volar carpal radial ligaments were thicker than dorsal ones. The injuries of SLIL, STmL, RSL and CLL were considered generally when SLG>4.78±0.54mm, STmG>3.71±0.32mm, RSG>5.77±0.79mm, CLG>4.62±79mm; when SLIL was incised completely, SLG>5mm. Keeping anatomic structure of SLIL and incising other ligaments, there existed no obvious variation in SLG. Keeping dorsal part and incising proximal and palmar ones, no obvious variation of SLG can be observed. Conclusions: There were no effects on SLG when carpal radial ligaments (except dorsal part of SLIL) were injuried .Dorsal part of SLIL played a very important role in keeping SLG normal.

Objective evaluate the role of vagus nerve?muscarinic cholinergic receptor ( M recep?tor) pathway in mitigation of myocardial ischemia?reperfusion (I∕R) injury by intrathecal morphine postcon?ditioning in rats. Methods Seventy adult male Sprague?Dawley rats in which intrathecal catheters were suc?cessfully placed without complications, weighing 250-350 g, were randomly assigned into 7 groups ( n=10 each) using a random number table:sham operation group (Sham group), I∕R group, intrathecal morphine postconditioning group ( MP group) , vagal transection ( VT) group, VT+ intrathecal morphine postcondi?tioning group (VT+MP group), atropine (ATP, M receptor antagonist) + morphine postconditioning group ( ATP+MP group) , and ATP group. Myocardial I∕R was produced by occlusion of the anterior descending branch of left coronary artery for 30 min followed by 2 h of reperfusion. Morphine ( 3μg∕kg, 10μl) was in?trathecally infused over 5 min starting from onset of reperfusion in MP group. Normal saline 10 μl was in?trathecally infused over 5 min starting from onset of reperfusion in NS group. The bilateral vagus nerves were transected at 10 min before reperfusion in VT+MP group. Atropine ( 0?1 mg∕kg, 0?5 ml) was intravenously infused over 5 min starting from 10 min before reperfusion in ATP+MP group. The occurrence of cardiac ar? rhythmia ( premature ventricular contractions ( PVCs) and ventricular tachycardia ( VT)∕ventricular fibrilla?tion ( VF) ) within the first 30 min of reperfusion was recorded. The rats were sacrificed at 120 min of reper?fusion, and myocardial specimens were obtained for determination of myocardial infarct size ( IS) as a per?centage of area at risk (AAR). IS∕AAR ratio was calculated. Results Compared with Sham group, the number of PVCs and VT∕VF and IS∕AAR ratio were significantly increased in the other groups. Compared with I∕R group, the number of PVCs and VT∕VF and IS∕AAR ratio were significantly decreased in MP group. Compared with MP group, the number of PVCs and VT∕VF and IS∕AAR ratio were significantly in?creased in VT+MP and ATP+MP groups. Conclusion Vagus nerve?M receptor pathway is involved in miti?gation of myocardial I∕R injury by intrathecal morphine postconditioning in rats.

ObjectiveBy the study of histological feature of the regenerated nerve at different time after operation,to explore the mechanism of the peripheral nerve regenerationwhen the distal nerve stump is repaired by a smaller proximal end with artery sleeve briding.MethodsFour Wistar rats were served as the donors of arteris for bridging.Sixteen Wistar rats were randomized into 2 groups (n =8 per group).In control group,the right sciatic nerves were cut off and received epineurial suture.In experimental group,the right sciatic nerves received artery sleeve bridging in different size.HE staining was taken to observe the histological changes of the regenerated nerve at 7,14,21 and 28 days after operation.ResultsThe new regenerated axons need about 21 days to pass the bridging gap.Twenty-eight days after operation,the number of the regenerated axons in distal segment was greater than that of the proximal in the experimental group.The regenerated axons were matured and more regular.Conclusion The functional reserve of repaired nerve is exists when the proximal end is smaller than the distal in size by means of amplification effect.And the method of artery sleeve bridging provides a better situation for functional reserve.

OBJECTIVE: The role of different local flaps in small external nasal skin defect reconstruction was discussed. METHOD: Forty-two cases of the small size nasal defects (diameter < 2 cm) were repaired with local external nose flap (includes the dorsal nasal flap, nasolabial flap and bilobed flap). The clinical and follow-up data were analyzed of patients with small external nasal skin defects, who accepted different local flaps reconstruction. Dorsal nasal flap, nasolabial flaps (includes island flap, slid flap and axial flap) and bilobed flap were tailored to reconstruct different external nasal defect. Twenty-seven patients were male and fifteen patients were female, the patients' age ranged from 28 to 74 years, the median age was 61 years. Thirty-eight cases resulted from resection of skin malignant tumor and four cases were benign lesions. The diameter of defects was 1-2 cm. The defects were reconstructed by single-stage dorsal nasal flap in 7 cases. There were 30 cases of caudolateral nasal defects were reconstructed by nasolabial flap, single-stage island nasolabial flap in 7 cases, axial flap in 18 cases and slid flap in 5 cases. Superior lateral defects were reconstructed by single-stage bilobed flap in 5 cases. RESULT: All defects were repaired successfully. All tissue flaps survived and had not necrosis. There was no tumor recurrence during 3 months to 2 years follow-up. CONCLUSION The dorsal nasal flap, nasolabial flap and bilobed flap can be used safely and effectively to repair the small external nasal defect and have satisfactory curative effect.
