Objective To compare the levels of thrombomodulin in acute cerebral infarction patients with different blood glucose levels.Methods Four hundred and eighty-nine patients with acute cerebral infarction were selected including 237 patients of non-diabetes (non-diabetes group),117 patients of diabetes and HbA1c ≤7.0％(diabetes controlled well group) and 135 patients of diabetes and HbA1c ＞7.0％ (diabetes controlled badly group).The level of thrombomodulin was assayed by enzyme-linked immunosorbent assay and compared among three groups.Results The level of thrombomodulin was (2.66 ± 1.20) μg/L in non-diabetes group,(2.80 ± 1.43) μg/L in diabetes controlled well group,(3.22 ±1.60) μ g/L in diabetes controlled badly group.There was the increasing of thrombomodulin among non-diabetes group,diabetes controlled well group and diabetes controlled badly group (P =0.030).There was difference between non-diabetes group and diabetes controlled badly group (P =0.008).Conclusion There is the increasing of thrombomodulin in patients with acute cerebral infarction when their blood glucose rising.

Objective To analyze the relationship between age and the prognosis of patients with pancreatic neuroendocrine tumors (pNETs).Methods The clinical data of 102 patients with pNETs who were admitted to the Zhongshan Hospital of Fudan University from January 1999 to December 2010 were retrospectively analyzed.The properties of the tumors were determined by morphology and immunohistochemical staining of chromogranin A,synaptophysin and neuron-specific enolase.Preoperative grading of the tumors was done by mitotic count and Ki67 proliferation index,and the staging of the tumors was done by ENETS TNM system.All patients were divided into younger group (age≤60 years,77 patients) and older group (age ＞ 60 years,25 patients).The survival of the patients was estimated using the life table,and the survival curve was drawn by the Kaplan-Meier method.The survival of the 2 groups was compared using the Log-rank test.Multivariate analysis was performed with the COX proportional hazards model.Results The median survival time was 139.8 months.The overall 1-,2-,5-,and 10-year survival rates were 96％,93％,90％ and 80％,respectively.The postoperative survival time of patients in the younger group was significantly longer than that in the older group (x2 =4.717,P ＜ 0.05 ).The prognosis of patients with higher tumor grades ( G2,G3) and higher TNM stages ( Ⅲ,Ⅳ ) in the older group was significantly poorer than those in the younger group ( x2 =11.158,5.375,P ＜ 0.05 ).The results of multivariate analysis showed that age and major vascular invasion were the independent predictors for survival (RR =8.626,12.795,P ＜0.05 ).Conclusions Age above 60 years is an important independent factor influencing the prognosis of pNETs patients.Tumor grading and TNM staging are highly correlated with the prognosis of the pNETs patients.

Objective To investigate the clinicopathological features,treatment method and prognostic factors of the gastric neuroendocrine neoplasms (gNENs).Methods The clinical data of 80 patients with gNENs who were admitted to the Zhongshan Hospital of Fudan University from January 2002 to December 2011 were retrospectively analyzed.All the patients received gastroscopic examination.Patients with well-differentiated and diameter ≤ 2 cm gNENs received endoscopic mucosal resection or endoscopic submucosal dissection.Patients with poordifferentiated and diameter ＞ 2cm tumors received surgical resection of gNENs.Patients were followed up via phone call,mail or out-patient examination till October 31,2013.The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate.The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model.Results Fifty-eight patients had pain and discomfort in the epigastric region.Thirty-two gNENs were located at the cardia,40 at the body and 8 at the pylorus.Fortyfour gNENs were ulcerative type,25 were polypoid type,11 were protruded type.The mean diameter of the gNENs was 2.6 cm (range,0.4-7.5 cm).Twenty-seven gNENs were in grade 1,10 in grade 2 and 43 in grade 3.Forty-five gNENs were localized,34 gNENs had lymph node involvement (2 gNENs had distal metastasis),and 1 gNENs had distal metastasis.Thirty-one patients received endoscopic resection,and did not receive adjuvant therapy.Forty-nine patients (6 with gastric neuroendocrine tumor and 43 with gastric neuroendocrine carcinoma)received radical resection,including proximal subtotal gastrectomy in 16 patients,distal subtotal gastrectomy in 15 patients,total gastrectomy in 15 patients and distal subtotal gastrectomy + resection of the liver metastasis in 3 patients.Thirty-four patients received adjuvant chemotherapy and 15 did not receive adjuvant chemotherapy.Seventy-nine patients were followed up for a median time of 42.0 months (range,2.0-113.0 months).The mean time of survival was 75.6 months(range,2.8-100.8 months),and the 1-,3-,5-year overall survival rates were 91.3％,75.8％ and 66.5％,respectively.The 5-year survival rates of patients with gNENs in grade 1,grade 2 and grade 3 were 100.0％,100.0％ and 38.0％,respectively.The results of univariate analysis showed that the gender,treatment methods,adjuvant chemotherapy,types of tumor,tumor diameter,classification and staging of the tumor were correlated with the prognosis of the patients (x2=9.550,17.488,25.038,14.994,6.897,25.234,22.066,P ＜ 0.05).The results of multivariate analysis showed that the gender was the independent risk factor influencing the prognosis of the patients (RR =11.280,95％ confidence interval:5.353-19.121,P ＜ 0.05).Conclusions The clinical presentations of gNENs are often nonspecific.The main presentation of gNENs is pain in the epigastric region of the abdomen,and most of the gNENs are located at the cardia or body of the stomach.The staging and grading of the gNENs are varied,and the prognosis is related with the gender of the patients.Endoscopic or surigcal resection is the main treatment method for gNENs.Female patients have a better prognosis than male patients.

OBJECTIVE: To explore the role of the innate immune factors TLR2 and TLR4 in the pathogenesis of chronic rhinosinusitis (CRS) by detecting their expression in different clinical types of CRS and the normal control group. METHOD: Immunohistochemistry was used to detect the expression of TLR2 and TLR4 respectively in 21 cases (chronic rhinosinusitis with nasal polyps, CRSwNP) group, 15 cases (chronic rhinosinusitis without nasal polyos, CRSsNP) group, 11 cases recurrent CRSwNP group and 13 cases control group. Positive cells were counted under the microscope artificially, Mann-Whitney U analysis was applied for the ranked data, and one-way anova analysis was adopted to analyze the experimental group and control group. RESULT: (1) TLR2 and TLR4 expression had the same characteristics. Expression mainly concentrated in parts of the whole layer of epithelial basement membrane, cytoplasm of glandular cells, very few inflammatory cells such as monocytes and plasma cells in the cytoplasm, sometimes unknown cell nuclei positive expression. (2) The glandular cells were stained manual counting and color grading. TLR2 and TLR4 packet application Wilcoxon rank test Mann-Whitney U test analysis was not statistically significant (P > 0.05), measurement data within the group variance statistical difference between the groups (P < 0.05). CONCLUSION The Nasal mucosa can produce the innate immune factors TLR2 and TLR4. The different expression of TLR2 and TLR4 in the various clinical types of CRS suggests that they play the certain role in the pathogenesis of CRS.

Objective To evaluate the prevention of glucocorticoid -induced avascular necrosis of the femoral head(ANFH)with Tongluo Shenggu Capsule(TSC).Methods One hundred and twenty adult SD rats were randomized into six groups:normal control group,model group,clofibratum group and three -dose TSC groups(high -,moderate -and low -dose respectively).ANFH rat models were established by injection of glucocorticoid once per week and the med-ication groups were given drugs by ga stric infusion one time a day.The rats were killed in the fourth,eighth and twelfth week respectively.Then the macrosc opic and microscopic feature of the f emoral head were observed,and ink -p erfused specimens of the femoral head were detected and analyzed by auto -photograph software of Metamoph to evaluate the pre-ventive effect of TSC.Results In TSC groups,bone trabecula grew we ll,similar to the normal group;lacu nar bone per-centage was lower than that in the mod el group;fatty degeneration in marrow cavity of the femoral head was redu ced,andthe number of subcartilaginous bloo d vessels and their diameter were increased as compared with those in the model group(P

Objective To explore the expression of Ras-related protein 11(Rab11)in hypoxia, the effect of Rab11 on the invasion and migration of cervical cancer cell line SiHa and its possible mechanism. Methods SiHa cells were divided into 4 groups, the normoxic blank group (normal culture in normoxia), the hypoxic blank group (normal culture in hypoxia), the negative control group [transfection of negative control small interfering RNA(siRNA)in hypoxia], the Rab11-siRNA group (transfection of Rab11 siRNA in hypoxia). Western blot was used to examine the expression of Rab11, integrin α5, integrin β3, phosphorylated focal adhesion kinase(p-FAK), phosphorylated phosphatidylinositol 3 kinase(p-PI3K) protein, together with the expression of Ras correlative C3 creotoxin substrate 1(Rac1), which was critical in regulating cell invasion. The mRNA expression of Rab11 in the 4 groups was detected by realtime-qPCR. The cell invasion was detected by matrigel assay, while the cell migration was detected by transwell assay. Immunofluorescence was used to identify intracellular location of Rac1 in SiHa cell. Results (1) The expression of Rab11, intergrin α5, intergrin β3, p-FAK, p-PI3K and Rac1 in the normoxic blank group were 0.56±0.04, 0.33±0.03, 0.32±0.03, 0.36±0.03, 0.35±0.03 and 0.47±0.03, respectively. In the hypoxic blank group, they were 0.73±0.03, 0.74±0.03, 0.61±0.03, 0.62±0.03, 0.60±0.03 and 0.73±0.03, respectively. In the negative control group, their expressions were 0.72±0.03, 0.73±0.03, 0.59±0.03, 0.61±0.03, 0.59±0.03 and 0.72±0.03, respectively. While in the Rab11-siRNA group, they were 0.44±0.03, 0.30±0.03, 0.29±0.03, 0.30±0.03, 0.30±0.03 and 0.34±0.04, respectively. The expressions of Rab11, α5, β3, p-FAK, p-PI3K and Rac1 were significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and were significantly lower in the Rab11-siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (2) The expressions of Rab11-mRNA were 1.000±0.000, 1.454±0.114, 1.442±0.101, 0.570± 0.046 in the normoxic blank group, the hypoxic blank group, the negative control group and the Rab11- siRNA group, respectively. It was significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and was significantly lower in the Rab11-siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (3) By Matrigel, the invasion cell number in the normoxic blank group, the hypoxic blank group,the negative control group and the Rab11-siRNA group were 65±12, 106±16, 104± 17 and 50±11, respectively. The invasion capacity was significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and was significantly lower in the Rab11- siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (4) By transwell assay, the migration cells in the normoxic blank group, the hypoxic blank group, the negative control group and the Rab11-siRNA group were 127±12, 169±15, 161±13 and 77±13, respectively. The capacity of invasion was significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and was significantly lower in the Rab11- siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (5) The immunofluorescence showed that the red fluorescence intensity around nucleus was significantly increased in the normoxic blank group, the hypoxic blank group and the negative control group than in the Rab11- siRNA group. Conclusions Hypoxia could promote the invasion and migration of SiHa cells. In hypoxia, the down regulation of Rab11 expression could inhibit the invasion and migration of SiHa cells. This might be due to the decreased expression of the intergrin α5, intergrin β3, p-FAK, p-PI3K and Rac1 protein.
