    Objective  To Compare the positive detection rates of hematoxylin and eosin stain with immunohistochemical stain by semi-consecutive sectioning of  histopathologically negative cervical lymph nodes from laryngeal or laryngopharyngeal squamous cell carcinoma.The  relationship between micrometastasis and clinicopathological factors,  micrometastasis and early recurrences was studied primitively. Methods  Totally, 326 negative cervical lymph nodes (CLNs) from 13 patients (15 sides), with laryngeal or laryngopharyngeal squamous cell carcinoma, were included in this study. Two methods( H&E stain and EnVison′s two-step IHC technique with monoclonal antibody CK (AE1/ AE3)) combined with semi--consecutive sectioning(per-50μm) were applied to detect the micrometestasis . The positive detection rates of H&E and IHC were compared by Chisquare test . The clinicopathological factors, consisted of sex, age, pT stage, clinical typing, grade of differentiation,depth of primary tumor invasion, were studied and all the cases were followed-up for 11~56 months(median time 31.4 months). Further, the relationship between micrometastasis and clinicopathological factors, micrometastasis and early recurrences were analyzed with Chisquare test.  Results  1. All the paraffin specimens of 75 cases were semi-consecutively sectioned into two sets of 750 slices for H&E stain and IHC stain. In the IHC group, 40(5.33%)slices were found positive in 7 (2.14 %) lymph nodes which came from 5(38.46 %) patients Howerver, only 24(3.20%)positive slices were found in 3 lymph nodes of 2 patients in the H&E group.The positive detection rates of these two groups were statistically significant(Ρ<0.05). 2. There was no statistically significance between micrometastasis and the clinicopathological factors (Ρ>0.05) except for the age (Ρ=0.032). There was no statistically significance between micrometastasis and early recurrences. Conclusion  1. Even the experienced pathologists may miss the micrometastasis in cervical lymph nodes from laryngeal or laryngopharyngeal carcinoma if only by H&E stain,though  semi-serial or serial section was applied in those cases.While the IHC technique can obviously increace the positive detection rates. 2.The possible relationship between micrometastasis and clinicopathological factors, micrometastasis and recurrences should be verified with more samples and long-term follow-up.

    Objective  To investigate the expressions and implications of focal adhesion kinase(FAK), matrix metalloproteinase(MMP9) in human squamous cell carcinoma of larynx. Methods  SP immunohistochemical technique was used to detect the expressions of FAK, MMP9 in 57 human squamous cell carcinoma of larynx and 10 paracarcinoma. Results  Positive expressions of FAK, MMP9 were found in 66.7% and 63.2% of laryngeal squamous cell carcinoma, which were significantly higher than those in paracarcinoma (10.0% and 20.0% respectively. P<0.05).The positive expression of FAK correlated with the clinical stage and lymph node metastasis(P<0.05), but not with patient′s gender, age, tumor location, tumor size or the degree of differentiation. So did  MMP9. Furthermore, the positive expression of FAK correlated significantly with the expression of MMP9(P<0.01). ConclusionIn   squamous cell carcinoma of larynx, FAK, MMP9 is overexpressed. Moreover,  the correlation between the expression of MMP9 and that of  FAK implies both play important roles in enhancing the metastasis and invasion of squamous cell carcinoma of larynx.

    Objective  To investigate the clinical characteristics of relapsing polychondritis(RP) with the involvement of respiratory tract. Methods  The clinical features, tests and treatment of RP with airway involvement in 3 patients were retrospectively reviewed. Results  Three RP cases of typical symptoms were confirmed by biopsy. CT scan with 3D reconstruction and bronchoscopy revealed the range and severity of the lesion. After initial medications, such as corticosteroids and immunosuppressive drugs, the symptoms in all cases alleviated significantly for a while but tended to recur and deteriorate later. During the follow-up, one recurrent case adopted laryngotracheal reconstruction in which pedicled surgical flaps was applied and a long-term stable condition persisted. Meanwhile, 2 cases died in the second and fifth year respectively after the diagnosis. Conclusion  RP with airway involvement is a rare disease affecting multiple systems in the body. The diagnosis is made on the clinical features, imaging studies and pathological examination. Early treatment with corticosteroids and immunosuppressive agents might achieve a relatively satisfying result at the beginning. However, in the later stage, invasive approaches, including tracheotomy, laryngotracheal reconstruction, should be applied for a better prognosis.

    Objective  To analyze the causes of incision hemorrhage after tracheotomy and to propose the treatment. Methods  14 cases had incision hemorrhage after tracheotomy. Some cases were treated by local packing with Vaseline gauzes when no blood entered trachea and all the bleedings  were contained. 2 days later, Vaseline gauzes were removed without rehemorrhage. For the patients in whom packing was not effective, we probed the incisions to ligate or cauterize the hemorrhagic spots. Then, we sutured the skin incisions to monitor the progress. Results  After tracheotomy, the causes and time points of hemorrhage varied, most cases had a fat and short neck.  Lots of hemorrhage was due to the injures to thyroid gland.  Conclusions  The causes and time points of hemorrhage are various.Serious consequences may occur. Therefore, we should treat it timingly and actively.
