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.

Objective To study the Ile796Val polymorphism in human SCAP gene in Hubei area, and analyze its correlation with coronary heart disease (CHP) and hypertension and the relationship between polymorphism and lipid metabolism. Methods Using PCR RFLP, we detected genotypes of Ile796Val polymorphism in human SCAP gene. Results The allele A frequencies of Ile796Val in human SCAP gene for controls, CHD patients and the hypertension patients were 0.32, 0.45 and 0.42 respectively. The allele G frequencies were 0 68, 0.55 and 0.58 respectively. There were significant differences in frequencies of genotype and alleles between controls and hypertension group. And there was significant difference in the level of TC, LDL C and ApoB. In CHD group, there was significant difference in the TC level between different genotypes. In hypertension patients, although a difference was noted in genotype, there was no significant difference in allele frequencies and lipid level exceps a significant difference in the levels of TC, LDL C and ApoB in hypertension patients. Conclusion Ile796Val polymorphism in human SCAP gene may be a great agent to cause disorder in the lipid level of blood and lipid metabolism of tissue. It is of great significance in disorder in lipid metabolism of inter cellular and genetic investigation of hyperlipidemia.

The formation of macrophage-derived foam cells is a typical feature of atherosclerosis (AS). Reverse cholesterol efflux (RCT) is one of important factors for the formation of macrophage foam cells. In this study, macrophage form cells were induced by oxidized low density lipoprotein (ox-LDL) and then treated with different concentrations of ferulic acid, so as to observe the effect of ferulic acid on the intracellular lipid metabolism in the ox-LDL-induced macrophage foam cell formation, the cholesterol efflux and the mRNA expression and protein levels of ATP binding cassette transporter A1 (ABCA1) and ATP binding cassette transporter G1 (ABCG1) that mediate cholesterol efflux, and discuss the potential mechanism of ferulic acid in resisting AS. According to the findings, compared with the control group, the ox-LDL-treated group showed significant increase in intracellular lipid content, especially for the cholesterol content; whereas the intracellular lipid accumulation markedly decreased, after the treatment with ferulic acid. The data also demonstrated that the mRNA and protein expressions of ABCA1 and ABCG1 significantly increased after macrophage foam cells were treated with different concentrations of ferulic acid. In summary, ferulic acid may show the anti-atherosclerosis effect by increasing the surface ABCA1 and ABCG1 expressions of macrophage form cells and promoting cholesterol efflux.

Objective To discuss the effect of light invasive treatment of endometrial in husband sperm intrauterine insemination outcomes.Methods A total of 248 patients receiving husband sperm intrauterine insemination were divided into two groups by random digits table method.The patients in light invasive treatment of endometrial group (138 cases with 246 cycles) were performed with light invasive treatment of endometrial,and the patients in control group (110 cases with 201 cycles) were not perfomed with light invasive treatment of endometrial.Human chorionic gonadotropin day of endometrial thickness,intrauterine insemination tube placed successfully or not,whether fertilization tube bloody and clinical pregnancy rates and so on were compared between two groups.Results There was no significant difference in human chorionic gonadotropin day of endometrial thickness between two groups (P ＞ 0.05).The success rate of intrauterine insemination tube placement in light invasive treatment of endometrial group was 78.5％ (193/246),which was higher than that in control group (65.2％,131/201),and there was significant difference (P ＜ 0.05).The intrauterine insemination tube bloody rate in light invasive treatment of endometrial group was 13.4％ (33/246),which was lower than that in control group (34.8％,70/201),and there was significant difference (P ＜ 0.05).The pregnancy rate in light invasive treatment of endometrial group was 31.9％ (44/138),which was higher than that in control group (18.2％,20/110),and there was significant difference (P ＜ 0.05).There were no significant differences in ectopic pregnancy rate and abortion rate between two groups (P ＞ 0.05).Conclusion Through light invasive treatment of endometrial the husband sperm intrauterine insemination outcomes can be improved.

Objective: To study the effect of tripterygium wilfordii polyglycosidium (TWP) on atopie dermatitis (AD) by detecting the expression of IL-2,IL-4,IFN-γ and IL-IO mRNA. Methods: RT-RCR was used to detect the mRNA of IL-2,IL-4, IFN-γ and IL-10 in peripheral blood mononuelear cells (PBMC)of AD cultured with different concentrations of TWP.ResuRs:(1)The expression of IL-2 was significantly different between the high concentration group and other groups(P＜0.05 or P＜0.01 ), and between the control group and the middle concentration group (P＜0.01). (2)The expression of IL-4 was significantly different between the three different concentration groups (P＜0.01 ). (3) The expression of IFN-γmRNA was significantly different between the high concentration group and the control, the low, the middle concentration groups (P＜0.05 or P＜0.01 ). (4)There was no significant difference in expression of IL-10 mRNA between the high concentration group and the middle concentration group (P＞0.05), there was significant difference among the other groups (P＜0.05 or P＜0.01).Conclusion: TWP can suppress the expression of IL-2, IL-4, IFN-γand IL-10 mRNA, but the low concentration of TWP can suppress the high-level expression of IL-4 and IL-10mRNA in vitro.

Objective To report two cases of Candida parapsilosis-caused candidiasis characterized by verrucous nodules and masses,and to assess their clinical features,diagnosis and treatment.Methods A medical history including medication history and therapeutic response was carefully collected from two male patients.Physical examination was carried out with a focus on skin lesions.Diagnosis was made according to medical history as well as physical,mycological and histopathological examination findings.Antifungal agents were given at a high enough dose in time.After lesions improved,the doses of antifungal agents were tapered gradually,and drugs were withdrawn until patients completely healed.Compound preparations containing both antifungal agents and glucocorticoids were also topically applied in the early period of treatment.Results Both patients were diagnosed as Candida parapsilosis-caused candidiasis characterized by verrucous nodules and masses,and cured after 100-day supporting treatment and antifungal treatment with oral itraconazole,etc.Conclusions Candida parapsilosis-caused candidiasis should be managed with combination therapy mainly including antifungal agents.To achieve a satisfying efficacy,antifungal agents should be given early at a high enough dose for a long enough period.

Aim To invesitgate the effect of PTEN(phosphatase and tensin homologue deleted on chromo-some ten) /PI3K(phosphatidylinositol 3 kinase) signaltransduction pathway in hypertrophied myocardium me-diated by overloaded pressure in rats,and the effect ofangiotensionⅡ(AngⅡ) receptors(AT1,AT2) antag-onists on it.Methods Overloaded pressure hypertro-phied myocardiumratmodel was established by abdom-inal arota constriction.Thirty two male wistar rats weredivided randomly into four groups,namely sham-opera-ted group,banding group,valsartan group(bandinggroup and valsartan administation),and PD123319group(banding group and PD123319 administration).AngⅡconcentration in plasma and left ventricular myo-cardium were measured by radioimmunoassays.Cardiacindex was measured and HE staining was performedwith left ventricular myocardium,immunoprecitipationwas used to assay the protein expression and phospho-rylation of PTEN、PI3K and Akt(Protein kinase B),protein expression of?-skeletal-actin in myocardial tis-sues.Results AngⅡ concentration in serum and leftventricular myocardium tissue in banding group washigher than that in sham-operated group,valsartangroup andPD123319 group(P0.05).Conclusions PTEN/PI3Ksignal pathway is involved in myocardium hyper-trophy in overloaded pressure rat model.The up-regu-lations of PI3K/Akt and down regulation of PTEN aremediated via AT1 and can be reduced by AT1 receptorantagonists.
