    Objective    To detect differentially expressed genes in hypopharyngeal carcinoma and adjacent normal laryngeal tissues with cDNA microarray. Methods      Three samples of hypopharyngeal carcinoma, pathologically confirmed as squamous cell carcinoma,  were tested.  Total RNAs were extracted and  inversely transcribed to cDNAs.The cDNAs of hypopharyngeal carcinoma were marked by Cy5 and  the cDNAs of normal laryngeal tissues were marked by Cy3. The cDNA probes were then hybridized to DNA microarrays and scanned for fluorescent signals. Differential expression between the two tissues was produced by ImaGene software. The average ratio of gray scale, if equal or more than 2 times,  was considered significant. Results      There were 51 genes significantly expressed in 3 cases. Among them, 39 genes were significantly higher, but 12 genes were significantly lower in hypopharyngeal carcinoma than  normal tisscle.4 new genes were identified. Some highly expressed genes (more than 5 fold difference ) included: 1) Genes of upregulation, such as MMP-1, Integrinβ4, Bcl-2, CXCL13 and PRAME; and 2) Genes of downregulation, such as Egr-1 and MRP1/ CD9. Conclusion     Many genes, which  play important roles in the proliferation, invasion, and metastasis of hypopharyngeal carcinoma, can be picked out by cDNA microarray;  These genes   will serve as targets for further research.

    Objective     To measure levels of serum soluble tumor necrosis factor receptors (sTNFR)  and   to explore their clinical significance in the diagnosis and monitoring of laryngeal cancer. Methods     The serum levels of sTNFRⅠand sTNFRⅡ were measured by avidinbiotin complex enzyme-linked immunosorbent assay (ABC-ELISA) in 42 laryngeal cancer patients and 40 healthy adults. Results      The serum levels of sTNFRⅠ in laryngeal cancer patients (1463.34±669.07pg/mL)were significantly higher than in the control group(549.30±293.29pg/mL, P<0.05), but the sTNFRⅡ levels were not  (P> 0.05); There was no significant difference among the levels of sTNFRⅠ and sTNFRⅡ in different types of laryngeal cancer(P> 0.05), while significant differences in the sTNFRⅠ level at the various developing periods of laryngeal cancer were found (P<0.05). The change of sTNFRⅡ levels, in the various periods of laryngeal cancer was of no significant difference (P>0.05). The sTNFRⅠ level of laryngeal cancer patients with lymph node metastasis were much higher than of  patients without lymph node metastasis (P<0.05), however, the difference of sTNFRⅡ levels between patients with and without lymph node metastasis was not significant (P> 0.05).Conclusion      Detection of serum levels of sTNFRⅠ may have practical value in the early diagnosis and  prognosis of laryngeal cancer.

    Object      To investigate the methodology and therapeutic effects of hyoid suspension in association with uvolopalatopharyngoplasty (UPPP) in the  treatment of severe Obstructive Sleep Apnea Hypopnea Syndrome(OSAHS). Method     21 patients with severe OSAHS underwent surgery of modified hyoid suspension in association with UPPP and were followedup. Polysomnograms (PSG)  were  examined pre-operatively and post-operatively in 21 Patients. All patients were the assessed  with Epworth Sleepiness Scale(ESS) and Berlin Sleep Quality Assessment Questionnaire(BSQAQ) before and after the operation. Results     The  results of follow-up showed that there were significant improvements in the indexes of PSG in  all cases (P<0.01). The average of the ESS was 6.71 6 months after operation and 7.24 after one year. Also, the average of the BSQAQ was 5.57 and 6.14 respectively ,with an obvious decrease compared to the preoperative data(P<0.01). After surgery, the patients told about the alleviation or disappearance of snoring and much less occurrence of sleep apnea while lethargy during the day was almost completely gone. According to the assessment guidelines, the effective rate was 100% 6 months after the operation and remained at 95.24% 1 year after the operation. But cure rate and effectual rate varied. Conclusion       Modified hyoid suspension in association with UPPP has advantages of simple procedure, less days of hospitalization and less expense. The effect of the operation is satisfying. Proper cases should be chosen to be treated with such procedure and more hospitals should adopt it.

    Objective     To observe the efficacy of adenoidectomy and tonsillectomy in children  with obstructive sleep apnea syndrome (OSAS). Methods      Sixty children with OSAS were selected after a PSG(polysomnography) test. The children were randomily divided into group A (30 cases) or group B ( 30 cases). In group A, adenoids and/or tonsils were ablated, while vitamin C (0.1mg) was administered orally in group B. Apnea-hypopnea index (AHI) and lowest blood oxygen saturation (SaO2), before and after 3month treatment in the two groups, were tested.  Clinical outcomes, in light of  the language evaluation form(VRS)furnished by the parents,  were also compared. Results     No obvious difference of AHI and the lowest SaO2  before the treatment was found between the groups. However, after three months of treatment, AHI reduced to 2.6±1.8, and the lowest SaO2 increased to 92.9±2.5 in group A, in which  all improved significantly compared with those before the treatment (P<0.05). Also,  AHI and lowest SaO2 in group B did not significantly change after the therapy (from 18.4±7.8 to 17.1 ±8.2, 79.2 ±11.4 to 81.4±9.1, respectively). According to the clinical outcomes, 86.7%, 93.3% and 86.7% of the children in group A improved in snore,  and suffocation or mouth breathing which were all better than those in group B (6.7%,13.3%, and 13.3%,respectively;all P<0.05). Conclusion      Adenoidectomy and tonsillectomy are effective  procedures to treat OSAS in children.

    Objective     To study the expression of neuro-specific enolase(NSE),  ofactory marker protein(OMP)and  apoptosis in the development of olfactory mucosa of mouse fetuses. Methods      Expressions of NSE and OMP in the olfactory mucosa of the different embryonic stages(day 13 to 21)were determined using immunohistochemical technique. The Tdt-mediated dUTP nick end-labeling technique (TUNEL) was used to detect apoptotic cells of the olfactory epithelium in different embryonic stages and to caculate the apoplotic index. Results       NSE immunological positive reactions were seen in different embryonic stages from E13 to E21. Otherwise, few positive OMP cells were observed after E14,  after E15  OMP-positive neurons were noticeably increased in the olfactory epithelium and at E17, they reached the peak. The apoptotic process in the olfactory epithelium was observed form E13 to E21. At E13, the apoptotic cells were few and the AI was low. A massive wave of cell death was evidenced between E16 and E18.The apoptotic index of E16 was noticeably distinction from other embryonic stages. Conclusion      Olfactory receptor neurons of mouse fetuses became mature at E14 and the quantity was small. In the anaphase of the embryo, the olfactory epithelium was mature. The apoptotic process takes part in the development of the mouse olfactory epithelium and comes to a peak in E16. Apoptosis is an active process in the development of mouse olfactory epithelium.
