Objective:To analyze the feature of cranial nerve involvement in nasopharyngeal carcinoma (NPC) and its relationship with the prognosis.Method:A total of 1892 patients who were diagnosed as NPC in our hospital from January 2002 to December 2003,of which the cranial nerve involvement was 183 (9.6%) patients, were analyzed the effect of cranial nerve involvement on the prognosis.Result:The percentage of cranial nerve involvement was 9.4%. The 5 year overall survival rate was 61.0%,disease free survival rate was 55.3%,local relapse free survival rate was 75.2% and distant metastasis free survival rate was73.4%.Periods of cranial nerve involvement,clinical stage,the diameter of the lymph nodes,involvement of cavernous sinus, and the level of the recovery of cranial nerve involvement were significantly associated with prognosis in univariate analysis(P<0.05).With multivariate analysis,the recovery level of cranial nerve involvement was the independent factor that affected the 5-year overall survival (RR=2.087). The diameter of the lymph nodes and involvement of cavernous sinus were the independent factors that affected the 5-year distant metastasis-free survival(RR=1.954 and 2.136,respectively).Conclusion:Periods of cranial nerve involvement and the level of the recovery of cranial nerve involvement were significantly correlated with prognosis. Involvement of cavernous sinus could increase the rate of distant metastasis.

Objective To investigate the correlation of medial meniscus extrusion with meniscus injury location, type and genu varum. Methods From March 2014 to March 2015, a total of 97 patients with injury of medial meniscus undergoing ar?throscopy and surgery were selected as subjects, including 40 males and 57 females, aged 32-66 years, with a mean age of 51.2± 10.71 years. Based on the MRI of knee, there were 38 cases with medial meniscus extrusion≥3 mm (extrusion group) and 59 cases without medial meniscus extrusion (non?extrusion group). Genu varus was measured on X?ray (Femur?Tibia?Angle<182°). The me?dial meniscus tear type was observed under arthroscopy (longitudinal tear, horizontal tear, oblique tear, radial tear, complex tear), as well as the meniscus tear location (anterior tear, body tear, posterior tear, root tear). The age, gender, BMI and involved side were compared between two groups. Multifactor unconditioned Logistic regression analysis was employed to analyze risk factors of medial meniscus extrusion. Results Two groups of patient showed no statistically significant difference in age (t=-1.511, P=0.135), gender (χ2=0.208, P=0.648), BMI (t=0.249, P=0.650) and side (χ2=0.052, P=0.820). The incidence of meniscus extru?sion in patients with genu varum was 89% (25/28), and the incidence of meniscus extrusion in patients with meniscus root tear was 78% (18/23). Significant difference could be spotted in the analysis of meniscal root tear (χ2=19.329, P=0.000), complex tear (χ2=5.111, P=0.024), genu varus (χ2=41.481, P=0.000) between patients with medial meniscus extrusion or without medial meniscus extrusion. Meanwhile, meniscus anterior tear (χ2=0.044, P=1.000), body tear (χ2=0.261, P=0.661), posterior tear (χ2=3.722, P=0.086), longitudinal tear (χ2=0.054, P=0.816), horizontal tear (χ2=0.317, P=0.790), oblique tear (χ2=0.198, P=0.819), radial tear (χ2=1.188, P=0.385) no statistical significance. By multifactor analysis, OR values of genu varus and root tear were 101.976 (95%CI:15.973, 651.041, P=0.000) and 35.517 (95%CI:6.804, 185.399, P=0.000), respectively. Conclusion Menis?cal root tear and genu varum were risk factors of medial meniscus extrusion.
