OBJECTIVE: Study the clinical characteristics, treatment results and prognostic factors of hypopharyngeal carcinoma. MMETHOD: A retrospective analysis was performed of 97 hypopharyngeal cases that were treated in Department of Dtolaryngology of our hospital from January 2008 to December 2012. 93 cases of them are male patients, and 4 cases are female patients. The tumors are originated from pyriform sinus(75 cases), posterior pharyngeal wall (16 cases) and post-cricoid area (6 cases). Of the 97 patients,21 patients were treated with partial hypopharynx resection (21. 6%), 7 were treated with partial laryngectomy+ partial hypopharynx resection (7. 2%), 53 were treated with total laryngectomy+partial hypopharynx resection (54. 6%), 12 were treated with total laryngectomy and total hypopharynx resection, gastric-pharyngeal anastomosis (12. 4%) and 4 were treated with total laryngectomy and total hypopharynx resection, enteric-pharyngeal anastomosis (4. 1%). Sixty-one cases undergo postoperative radiotherapy in Oncology. Use Chi-square test to do enumeration data analysis, the survival rate is calculated with the life table method, survival analysis with Kaplan-Meier method, parallel Log-rank test. Cox regression multivariate analysis model is used to find the factors affecting prognosis. RESULT: The follow-up rate of this group was 90. 7%. All patients' 1-year survival rate is 76. 0% , 3-year survival rate is 56. 0%, pathological lymph node metastasis rate is 71. 1%, occult lymph node metastasis rate is 19. 6%. Local recurrence rate is 21. 6%. The main reasons of death in patients include : cervical lymph node metastasis in 7 patients (21. 9%), local recurrence in 12 cases (37. 5%), distant metastases in 10 patients (31. 3%) and so on. Univariate analysis showed that tumor size (P<0. 01) and tumor T stage (P<0. 05) have impact on survival prognosis, no risk factors was found with Cox regression multivariate analysis. CONCLUSION Hypopharyngeal carcinoma is difficult to be found early, prone to recurrence and metastasis after operation, carefully chosen surgical excision and neck dissection, adjuvant postoperative radiation therapy is the main treatment strategy. Posterior pharyngeal wall carcinoma tend to have higer recurrence and metastasis rate than the other two types of hypopharyngeal caocinom, and treatment would cause much larger injury, so more attention should be paid to this type of hypopharyngeal caocinom.

ve To understand the impacts of industrial fluoride-induced pollution on environment and human health. Methods The contents of fluorides in environmental media, such as air, soil, vegetables, weeds, branches and leaves in area around a certain chemical factory (polluted area) were monitored. The prevalance of dental fluorosis, the contents of fluorides in hair and nail were investigated among 87 individuals without history of exposure to industrial fluorides, living in polluted area for more than 5 years, and 132 individuals in control area. Results Higher fluoride levels in environmental medias, higher prevalance rates of dental fluorosis, high contents of fluorides in hair and nails of population were found in polluted area compared with those in control area. Conclusion The in-dustrial fluoride-induced pollution from this chemical factory had resulted in the hazardous impacts on environmental quality and human health.

The extraction method and structure of exo-polysoccharide from schizophyllum commune by submerged cultivation were studied. Proteins were removed com p letely from the polysoccharide by the sevag method following the isoelectric poi nt precipitation method. The purified schizophyllan was proved to be homogeneou s with molecular weight 4?10 4D by sephadex G-200 column chromatography, PAGE and HPLC. Its monomer was determined by hydrolysis, PC, GC and its structure wa s analyzed by IR, enzymolysis, periodate oxidation, the results showed that schi zophyllan was only composed of glucose and it was the ?-glucan consisting of ?-(1-3) and ?-(1-6) glucosidic linkages.

Objective To investigate the related factors of clinical incidence and the ultrasound diagnostic value of endometrial polyps (EMP).Methods A total of 278 patients with clinical abnormal vaginal bleeding,menorrhagia,infertility,cervical polyps or physical examination showing EMP received vaginal ultrasound and hysteroscopy.The related clinical factors were recorded and single factors and multivariate unconditional Logistic regression analysis were carried.Results The univariate analysis showed that the number of pregnancy,menopause,placing intrauterine device,oral comtraceptives,history of hormone therapy,chronic endometritis,cervical polyp,merger endometriosis and obesity were the statistically significant factors of EMP incidence (P ＜ 0.05 or ＜ 0.01),which were used as dependent variables for multivariate Logistic regression analysis,indicating that menopause,chronic endometritis,history of hormone therapy and cervical polyp significantly affecting EMP incidence (P ＜ 0.05),with OR values of 4.068,4.122,3.770 and 3.983 respectively.Conclusion Menopause,chronic endometritis,history of hormone therapy,cervical polyps are the related risk factors of EMP.

Objective To investigate the mRNA expression of survivin, livin and XIAP gene in peripheral blood of patients with gastric cancer and its relationship with clinico-pathological features.Methods This study included 50 patients with gastric cancer and 20 healthy donors. The expression of survivin, livin and XIAP gene was detected by reverse transcription-quantitative polymerase chain reaction (RT-QPCR) using a molecular beacon probe, while recombination plasmid containing the sequence of survivin, livin and XIAP was standard. The relationship between copies of survivin, livin and XIAP gene expression in peripheral blood with gastric cancer and clinical data was analyzed. Results A linear standard curve was obtained between 103 ～ 1010 copies. The copies of survivin, livin and XIAP mRNA in peripheral blood of patients with gastric cancer did not correlate with gender, age, and histological types ( P ＞ 0.05). There were positive relationships between copies of survivin, livin and XIAP gene with lymph node metastasis and TNM stage (P ＜0.05 ). The expression of survivine, livin and XIAP was all negative in peripheral blood of healthy people. 52% (17/33) of patients suffered from recurrence or metastasis who had positive expression of survivin and/or livin and/or XIAP mRNA, while it was 18% (3/17)among the negative survivin and/or livin and/or XIAP mRNA caces ( P ＜ 0.05). Conclusions The expression of survivin, livin and XIAP mRNA can be used to detecte micro-metastasis in peripheral blood circulation of gastric cancer.

Objective To explore the value of evaluating rat liver fibrosis using contrast enhanced sonography.Methods Carbon tetrachloride was used to induce liver fibrosis.Under the mode of pulse-inversion harmonic imaging,ultrasound contrast agent was bolus iniected through tail vein,hepatic artery arrival time(HAAT),portal vein arrival time(PVAT),hepatic vein arrival time(HVAT)was recorded,and their relationship with immunohistochemical results were analyzed.Results There was no statistical difference of HAAT,PVAT between two groups among S0-S4 stage.HVAT was shorter in S3 and S4 stage than in S0-S2 stage(P＜0.05).HVAT was negative correlated with the percentage of immunohistochemical positive area of C-Ⅳ,LN,the correlation coefficients were-0.680 and -0.639 respectively.Conclusions Contrast enhanced sonography is useful for the diagnosing liver fibrosis.

Objective To investigate the effect and mechanism of phosphorylated protein kinase R-like ER kinase(p-PERK) and C/EBP homologous protein(CHOP) after hypoxic-ischemic brain damage ( HIBD) . Methods Neonatal 7-day-old Sprague Dawley rats were divided into sham-operation control group and HIBD group( n=30 per group) . Each group was divided into 0 h,6 h and 24 h subgroup after operation ( n=10 per group) . The ratio of apoptosis of brain cell was measured by flow cytometer and the expression of p-PERK and CHOP were detected by Western blot. Results (1)Apoptosis cell appeared at 6 h in HIBD group,the ratio of cell apoptosis was(2. 17 ± 0. 19)%. The apoptosis cell obvious increased at 24 h,the ratio of cell apoptosis was(13. 42 ± 0. 83)%. There was a significant increase in the ratio of apoptosis after HIBD 6 h and 24 h, as compared with sham-operation control group [ ( 0. 57 ± 0. 06 )%( P <0. 01 ) ] . ( 2 ) The expression of both p-PERK and CHOP was very low in sham-operation control group. In the HIBD group,the expression of both p-PERK and CHOP began to increase at 6 h and increased furthermore at HIBD 24 h. The differences in the expression levels of p-PERK and CHOP in HIBD group among different time points were significant( P<0. 01 ) . ( 3 ) The expression of p-PERK positively correlated with the expression of CHOP (r=0. 997,P< 0. 05). Conclusion With the emerging of apoptosis after HIBD,the expression of both p-PERK and CHOP increases. The imbalance in the expression of PERK induces the apoptosis of brain cells in the HIBD of neonatal rats by regulation of CHOP expression.
