Objective: To study the correlation between the expression of CD44s, CD44v6 and theclinicopathological characters of laryngeal squamous cell carcinoma (LSCC) so as to analyze the role of them inoccurrence and progression of LSCC. Method:Expression of CD44 and CD44v6 in 46 cases of LSCC and 20 casesof adjacent normal tissues was inspected with immunohistochemical SP method. Result:The expression of CD44sincreased significantly in lymphnode metastasis group (94.4%) and stage Ⅲ~Ⅳ group (96.2%),but decreasedin non-lymphnode metastasis group (67.9%) and stage Ⅰ~Ⅱ group (55.0%). The expression of CD44v6 waslower (21.7%),which wasn′t associated with any clinicopathological characters. Conclusion:The role of CD44and CD44v6 in carcinoma maybe dependent on the species,type of carcinoma, and the expression of CD44s maybe a biologic marker to evaluate metastasis of LSCC.

Objective To investigate the necessity to test the hearing of patients whose initial symptom is tinnitus with pure tone audiometer. Methods To analyze the results of pure tone audiometer of 218 tinnitus patients.Results Among 218 cases of tinnitus patients,a total of 123 patients with abnormal hearing,among 95 cases of patients with normal hearing, except for 50 cases of tinnitus, no other cause of disease. Conclusion Among the normal hearing tinnitus patients, we should do further hearing test for them if they are not identified a clear cause of disease,such as auditory brainstem response,otoacoustic emission and other necessary checks to clear the reasons for tinnitus or the position of the unusual auditory system. It is important for early diagnosis and treatment of tinnitus. But the pure-tone audiometer should be a routine examination when tinnitus patients come for the first visit.

Objective To explore microbic distribution feature of acute rhinitis pafienta' nasal cavity and dependabihty research of respiratory infection.Methods 436 acute rhinitis pafienta were randomly divided tO infection group(314)and non-infection group(122)depended on whether accompanying respiratory infection.Take blenna narium and carry out nasal cavity microbiological detection,meanwhile take blood and mesasure the content of serum IL-4 and IFN-γ.Results The staphylococcus aureus taked the most proportion(58.6%and 3 1.2%)of nasal cavity bacterial distribution in infection group and non-infection group,the following bacterium were the staphylococcus epidermidis(44.9%and 46.7%),bacillus meningitidis purulentae(7.9%and 4.9%)and bacillus coli(3.5%and 1.6%),the major eumycete were the peptostreptococcus asaeeharolyticus(1.9%and 1.6%),eubacterium lentum (1.6%and 0)and eubacterium mucus(0.9%and 0.8%),the major virus were the syncytial virus,the rhinoviru8es,adenodrus,influenza virus,parainfluenze virus and coronaviruses.The respiratory tract infection patients' content of serum IL-4 Were significant higher(P<0.05)than the non-infection group,but the content ofIFN-γ were signifieanfly reduced(P<0.05).Conclusion The staphylococcus aureus,syncytial virus,rhinoviruses,adenovirus and influenza virus have the close relation with the infection of the respiratory tract,which can cause the disorder of organism immune function.

OBJECTIVE:
To analyze the oncological outcomes, functional outcomes in patients undergoing supracricoid partial laryngectomy (SCPL). Provide clinical experience for application of SCPL.
METHOD:
A retrospective analysis of the 115 cases with laryngeal carcinoma accepted SCPL in our department from Jan 1996 to Dec 2004. Use the Kaplan-Meier method to analyze the patients'survival rate. Evaluate the value of reserve larynx function.
RESULT:
The 5-years survival rates and the decannulation rate was 80.8%, 99.1% respectively; and the average decannulation time was 22.25 days. The mean time of removal of gastric tube was 9.57 days. The function of CHEP was superior to CHP. The vocal function of 115 cases were all achieved in general communication.
CONCLUSION
SCPL get better oncological and functional outcomes and allows the preservation of the basic function of the larynx. It's a safe, effective technique and deserved to generalization.

OBJECTIVE:
To investigate the operative methods of invasive head and neck neoplasms involving skull base.
METHOD:
Thirty-two cases with invasive head and neck neoplasms involving anterior and lateral skull base, from 1997 to 2005, were treated with surgical resection. Nine surgical approaches including endoscopic transnasal approach for five cases, combined craniofacial approach for three cases, maxillary resection approach for 15 cases, transpalatal approach for one case, transmandibular approach for one case, lateral neck-mandibular incision approach for two cases, combined retroauricular and neck approach for one case, frontotemporal approach for two cases, and facial translocation approach for two cases were used to resect the tumors.
RESULT:
Four cases with nasal sinus mucocele were only applied drainage and one case with chordoma was subtotally resected. The tumors of the rest 27 cases were totally removed. Although one case complicated with cerebrospinal fluid leak and recovered within one week, no one died from the operation and no serious cranium-cerebrum complication occurred. Eight cases with benign tumor were followed up for six months to eight years without recurrence and no one died. For 24 cases with malignant tumor, survival rates of three and five years were 63.2% (12/19), 41.7% (5/12) respectively.
CONCLUSION
Surgical approach must be designed according to the pathological change's characters, site and invasive range. Favorable curative effect could be achieved by resecting tumors totally as possible, protecting important constitutions, and adopting proper reparative techniques.

Long non-coding RNA regulates gene expression at multiple levels (epigenetics,transcriptional level,post-transcriptional level) and plays an important role in the development and progression of individual development and tumors.With the deep research,it is found that LncRNA CRNDE is an important cancer-related long non-coding RNA,and it is necessary to understand the specific role of LncRNA CRNDE in regulating tumor cell life activities.In recent years,the role of LncRNA CRNDE in tumorigenesis and development has been increasing.It has been found that LncRNA CRNDE is up-regulated in various tumors and is closely related to tumor proliferation,invasion,metastasis and patients' prognosis,becoming a new hot spot in cancer research.The author combines the latest literatures at home and abroad to review the role and mechanism of LncRNA CRNDE in the development of digestive system tumors,hoping to prevent and treat tumors in the future.
