Objective To explore the trend of mortality and years of life lost due to Esophageal Cancer in residents in Tieling,so as to provide the basis data on preventing Esophageal cancer in Tieling.Methods The data of residents in Tieling dying of Esophageal cancer from 2007 to 2015 was collected and cleared up to calculate the evaluation indexes including the mortality rate,the average percentage change of mortality rate.GM(1,1) model was used to predict the future mortality.Results From 2007 to 2015,the Average Esophageal cancer Mortality Rate of in residents in Tieling was 5.26 per 100000 persons,and especially 1.95％ raised a year.The Mortality Rate would increase from 2016 to 2019.Conclusion Tieling Esophageal Cancer mortality rate is on the rise,especially for elder men more than 60.So that the proper prevention measures should be car ried and strengthened.

OBJECTIVETo explore the mechanism of polypeptide extract from scorpion venom (PESV) on inhibiting angiogenesis.

METHODSThe H22 hepatoma tumor model was established by subcutaneously implanting H22 hepatoma cells into mice. The tumor-bearing mice were randomly divided into 4 groups, i.e., the control group, the high dose PESV group, the low dose PESV group, and the 5-fluorouracil (5-Fu) group, 10 mice in each group. The intervention was lasted for 14 days. The growth curve of the tumor volume was drawn and the inhibition rate calculated. Pathological changes of the tumors were observed by HE staining. The microvessel density (MVD) was detected using SP method. The protein expression levels of phosphatidylinositol 3-kinase (P13K), phosphoprotein kinase B (P-Akt), hypoxia-inducible factor-1 alpha (HIF-1 )alpha, and vascular endothelial growth factor-A (VEGF-A) were detected by immunohistochemical assay and Western blot.

RESULTSThe tumor inhibitory rate was 64.8%, 43.7%, and 32.4% in the 5-Fu group, the high dose PESV group, and the low dose PESV group. Compared with the control group, the protein expression of PI3K, P-Akt, HIF-1alpha, and VEGF-A were obviously inhibited by PESV and 5-Fu (P <0. 05,P <0. 01). The MVD also decreased in the high and low dose PESV groups (P < 0.05).

CONCLUSIONSPESV could inhibit the angiogenesis of H22 hepatoma. The mechanisms might be associated with suppressing the expression of PI3K, P-Akt, HIF-1 alpha, and VEGF-A.

Objective To investigate the effect of dexmedetomidine combined with butorphanol conventional therapy on sustaining sedation of intensive care unit (ICU) patients.Methods Sixty critically ill patients in Binzhou Central Hospital from June to September in 2014 were randomly divided into experimental group and control group, 30 cases in each group. In the control group, 0.8 mg/L dexmedetomidine hydrochloride injection (400μg with addition of 46 mL normal saline to form 50 mL solution) was intravenously infused continuously at a speed of 0.4μg·kg-1·h-1 by a micro-pump to induce analgesia and sedation; while in the experimental group, dexmedetomidine combined with 200 mg/L butorphanol (10 mg plus 40 mL normal saline to form 50 mL solution) was given for intravenous infusion by a micro-pump with a speed of 0.01 mg·kg-1·h-1 to maintain analgesia and sedation for 48 hours whose required Ramsay score in both groups was 3 - 5. Before and after treatment, the changes of heart rate (HR), respiratory rate (RR), mean arterial pressure (MAP), arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), and the pulse oxygen saturation (SpO2) of both groups were observed. The dosage of dexmedetomidine used for maintenance of required analgesia and sedation and FPS (facial expression) grading and Ramsay score were compared respectively between the two groups, and the clinical efficacy of the two groups were evaluated.Results After treatment, the HR, MAP, RR in both groups were significantly lower, and PaO2 and SpO2 were significantly higher than those before treatment, and the degrees of improvement in the above indexes of the experiment group were superior to those of the control group [HR (bpm): 84.58±12.43 vs. 118.62±14.21, MAP (mmHg, 1 mmHg = 0.133 kPa): 82.35±12.12 vs. 92.35±12.32, RR (times/min): 25.42±3.98 vs. 32.87±5.12, PaO2 (mmHg): 95.21±10.55 vs. 75.18±8.57, SpO2: 0.981 4±0.102 8 vs. 0.954 7±0.093 8, allP < 0.05]. The total therapeutic effect in experiment group was significantly higher than that in control group [93.3% (28/30) vs. 76.7% (22/30),P < 0.05]. The dexmedetomidine dosage used in the experiment group was much less than that in the control group (μg/d: 412.12±23.18 vs. 520.05±15.68,P < 0.05). The FPS score in the experiment group was obviously lower than that in the control group (1.48±0.16 vs. 2.52±0.74,P < 0.05).Conclusion In comparison, to achieve sustained and required analgesic and sedative effect for ICU patients by combined use of dexmedetomidine and butorphanol, the dosage of dexmedetomidine used is less than dexmedetomidine applied alone, in addition, the combined use can achieve better Ramsay grading, steady blood pressure and excellent effect.

BACKGROUND: The growth behaviors of cells on the biomaterials scaffold may be affected by the topography, pore size, wettability, porosity and other factors.OBJECTIVE: This research is aimed to observe the growth and proliferation of Schwann cells in silk fibroin scaffolds with different pore sizes. METHODS: Two kinds of silk fibroin scaffolds with different pore sizes were prepared, including a large pore size scaffold (pore size 50-60 μm) and a small pore size scaffold (pore size 10-20 μm). Schwann cells (R3 [33-10ras3]) served as seed cells and incubated in 37 ℃, 5% CO2 incubation box. When cells filled up the culture bottle bottom and formed a dense monolayer, they were digested and the cell concentration adjusted, then Schwann cells were seeded onto the surface of the porous silk fibroin scaffolds with different pore sizes. After seven days of co-culture, the growth and proliferation of Schwann cells were observed under scanning electron microscope.RESULTS AND CONCLUSION: The growth of Schwann cells on the surface of silk fibroin scaffolds with different pore sizes was varied. On the surface of small pore size scaffold (10-20 μm), the cell density was low, while the phenotype of cells was bipolar, cells arranged in parallel or linked as the cell chains. On the surface of large pore size scaffold (50-60 μm), more cells could be seen, but most of the cells were in the shape of single sphere, cells clustered on the surface of the porous scaffold or aggregated as a bunch of grape at the bottom of pores. Only few cells were bipolar and lied on the ridge between the pores. The result showed that the pore size of porous silk fibroin scaffolds is an influential factor for the growth and adhesion of Schwann cells. Schwann cells are conducive to grow on the scaffolds with pore size larger than cell body diameter.

Objective To evaluate the expression of macrophage migration inhibitor factor (MiF) and cyclinD1 in pancreatic carcinoma and their relationships with clinical pathology characteristics. Methods The expression of MIF and eyclinD1 in 89 carcinoma and 5 normal pancreatic tissues was detected with immunohis-tochemistry methods, and the relationships among MIF and cyclinD1 expression and clinicopathological factors were studied. Results The overexpression of MIF and cyclinD1 was found in 88.8%, and 50. 6% of pancre-atic carcinoma tissues respectively. The overexpression of MIF had a significant correlation with Ⅰ,Ⅱ,Ⅲ,Ⅳ tumor stage (69. 2%, 94. 7%, 96. 4%, 100%, P <0.05), while the positive expression rate of cyclinD1 only had a significant correlation with tumor stages Ⅲ,Ⅳ (33. 3%, 68. 8%, P <0. 05). Both of the two proteins had a correlative tendency with pathological grade and lymph node metastasis. The different expression of MIF between pancreatic carcinoma with and without liver metastasis had no statistical significance, (100% ,85.9%, P >0. 05)while there was a statistically significant difference about cyclinD1 (66. 7% ,46. 5% ,P <0. 05). A significant positive correlation was also found between MIF and cyclinD1 (P < 0. 05). Conclusion The ex-pression of MIF and CyclinD1 was higher in pancreatic cancer tissues than in normal tissue, and they may be associated with the malignant stage, tumor differentiation, local lymph node and liver metastasis of this tumor.
