Objective To explore the influence of lung IL-10 on interstitial dendritic cells in multiple organ dysfunction syndrome(MODS),and its role in immunological dysfunction.Methods The model of MODS was replicated by injecting zymosan into the peritoneal cavity of C57BL/6 mice.The mice were then randomly divided into normal groups as well as the groups of 3-6 hours,12-48 hours,5-7 days and 10-12 days post trauma.The level of CCR7 mRNA in lung was detected by RT-PCR and the proteins of CCR7 and IL-10 were immunohistochemically stained.The number of mononuclear cells in MHC-II positive peripheral blood was determined by flow cytometry.Results At the early stage of injury(3-6 hours),the number of IL-10 positive cells and the expression of CCR7 increased,but the number of mononuclear cells in MHC-II positive peripheral blood decreased.At the stage of 12-48 hours,the number of IL-10 positive cells and the expression of CCR7 continued to increase obviously,and that of mononuclear cells in MHC-II positive peripheral blood went on decreasing.At the stage of 10-12 days,the number of IL-10 positive cells increased dramatically compared with that in normal group,but the expression of CCR7 declined obviously in contrast to that in 12-48 hours,and the number of mononuclear cells in MHC-II positive peripheral blood decreased to the lowest level.Conclusions The expression of IL-10 in lung could inhibit the excessive immunological damage induced by dendritic cells on the one hand,and it probably leads to immunosuppression by reducing the CCR7 expression of dendritic cells and the number of mononuclear cells in MHC-II positive peripheral blood on the other hand.

Objective To explore the role of kidney interstitial dendritic cells in irnmunodissonance moechanism in mice with multiple organ dysfunction syndrome(MODS).Method The model of MODS wasmade by injecting zymosan into the peritoneal caiecty of C57BL/6 miee,and the mice were randomly divided into 5 groups,namely,normal,3～6 hours,12～48 hours,5～7 days,10～12 days after administrating zymosan. Pathological changes of kidney interstitial dendritic cells were observed by transmission electronic microscopes. Specific sudaee markers CD205,CD11e,CDSO,MHCⅡmolecules I-A~b,CD4~+ and CD8~+T lymphocyte subgroups in peripheral blood were detected by immunohistochemistry and flow cytomctry.Results In acute injury stage,in comparison with normal group,interstitial dendritic cells had a continuous proliferation with high expression of CD80 and I-A~b(P

Objective To introduce the experience of management of inverted papilloma in frontal sinus in hospital. Methods Six patients with inverted papilloma in frontal sinus treated between 1999 and 2006 were reported, with special emphasis on the clinical symptoms, surgical technique and prognosis. Results Among 6 patients with frontal sinus involvement, there were 5 males and 1 female, aged between 24 and 66 years. All 6 patients were managed with endoscopic resection and additional open approach (giabellar nasal keyhole approach). Follow-up ranged from 2 - 8 years. Five patients treated with this protocol remained disease free, and 1 patient died of tumor recurrence and malignant degeneration 16 years after the first surgical management of sinonasal inverted papilloma. Conclusions The appropriate management of inverted papilloma involving the frontal sinus is combined open/endoscopic approach. The tumor extended into the lateral, far superior, and anterior aspects of the frontal sinus is truly at the limits of current endoscopic instrumentation. In order to avoid recurrence, the tumor must be reseeted completely during the operation. Postoperative radiotherapy is not absolutely necessary.

Objective To evaluate the effect of endoscopic surgery for advanced malignant tumors in the nasal cavity and paranasal sinuses. Methods A retrospective data analysis was performed on 49 patients with advanced sinonasal tumors undergoing either an exclusive endoscopic approach or with a complemental approach from January 2004 to October 2010. Forty-nine patients were considered eligible for editions of the UICC staging systems). The histotypes encountered were squamous cell carcinoma 20 cases,adenocarcinoma 12 cases, mucosal melanoma 8 cases, olfactory neuroblastoma 6 cases, others 3 cases.These patients were operated on either by an exclusive endoscopic endonasal approach or with a complementary external approach; 36 patients received adjuvant radiotherapy or/and chemotherapy. The data were analyzed by Kaplan-Meier method and Log-rank test. Results The hemorrhage varied from 200 to 5000 ml during the operation, with an average of 600 ml. The post-operative complications were rare,1 patient lost her sight after operation, and no patient got infected at the site of operation (nor intracranial infection). After full amount of radiotherapy, no cerebrospinal fluid rhinorrhea was found. Four patients ( 8. 2% ) lost to follow-up. Sixteen patients died during the follow-up period, only three of them were without craniocerebral or orbital invasion. Four in 9 patients in the other pathological group (with the pathology of olfactory neuroblastoma or glioma etc) , which had a poor prognosis, died during the follow-up period, of them, 3 had definitive evidence of intracranial metastasis, and none of the nine patients had been followedup beyond 25 months. The 2 and 3 year disease-free rates were 34. 2% and 21.4% , and overall survival rates were 62. 5% and 58. 4% respectively. The T stage, margin status, and whether accepted post operative adjuvant therapy were significant factors in predicting disease recurrence(x2 were 7.7, 4. 9, 6. 8 respectively and P <0.05). Conclusions Now the endoscopic techniques with or without complementary approaches is an effective way for complete tumor removal. With postoperative complementary therapy, it provides a satisfactory survival rate with few side effects and better quality of life.

OBJECTIVETo analyze the reliability and validity of the Fatigue Self-assessment Scale (FSAS).

METHODSThe scale was applied among the participants assigned to 4 groups, the differences in types, degrees and characteristics of fatigue of them were compared, and the reliability and constitutional validity of ESAS were assessed by internal consistency analysis, exploratory factor analysis and confirmatory factor analysis using the statistical software of SPSS and LISREL.

RESULTSStatistical differences of types, degrees and characteristics of fatigue presented in the participants of the 4 groups. The Cronbach's alpha of various factors in the scale were 0.772-0.908; the indexes for the section of assessing type, and degree of fatigue were RMSEA=0.065, NNFI=0.95, CFI=0.96; and those for the section of assessing characteristics of fatigue were: RMSEA=0.10, NNFI=0.93, CFI=0.96.

CONCLUSIONThe FSAS has good differentiability, reliability and constitutional validity for assessing the type, degree and characteristics of fatigue in various populations. In order to explore the relationship of TCM syndrome patterns with the type, degree and characteristics of fatigue, its future application for evaluation of fatigue and intervention effect of anti-fatigue should be combined with TCM syndrome differentiation.

Objective To explore the difference of four calculating methods used to determine the obesity. Methods Two thousand four hundred and forty six (2446) men and three hundred and seventy nine (379) women were measured height and body mass, Standard body mass, BMI, body fat ratio and obesity index(OI) were calculated with formula. According to the BMI≥ 25 kg/m2 , BMI ≥ 27 kg/m2 and BMI≥28 kg/m2, the obese adults were 1419,680 and 435 respectively;there were 649 adults that their body mass was over 20％standard body mass; there were 639 adults that their body fat ratio was over 25％(male)and 33％(female). Results For obesity determination, the adults who were 20％overweight and over standard body fat ratio were significantly different from those whose BMI were over 25 kg/m2 ( P＜0. 05 ) ;Those who were 20％overweight and over standard body fat ratio were not significantly different from those whose BMI were over 27 kg/m2 ( P＞0.05 ) ; Those who were 20％overweight and over standard body fat ratio were significantly different from those whose BMI were over 28 kg/m2 ( P＜0. 05 ). Conclusion Determining obesity with BMI≥27 kg/m2 is feasible and rational.

Objective:To explore CCR7 expression in splenic dendritic cells and its role in migration and activity of splenic dendritic cells in multiple organ dysfunction syndrome (MODS) in mice.Methods:The MODS model of mice was reproduced by Zymosan injection into peritoneal cavity.The mice were randomly divided into groups of normal,3-6 hours,24-48 hours and 10-12 days post zymosan injection.CD11c and CD205 were analysed by immunohistochemistry;The expression of CD86 and CCR7 of DCs were studied by the flow cytometry analysis.Results:In normal mice,many DC were found at the margin between the red and white pulp.In the 3-6 h and 24-48 h groups,CD86 and CCR7 were strongly up-regulated in the DC,and they distributed in T cells areas.In the 10-12 d group,DC distributed at the margin by the immature form.Conclusion:The CCR7 expression level of DC has close correlations with the migration of DC,CCR7 can be used to evaluate the migration and functional activity of DC in MODS.
