Objective To understand the pathogenetic role and clinical significance of interleukin 6(IL－ 6 ),tumor necrosis factor(TNF) and soluble interleukin－ 2 receptor(sIL－ 2R) in patients with cerebral infarction(CI) .Methods The IL－ 6,TNF and sIL－ 2R levels were measured in 46 CI patients with ELISA. Results The serum IL－ 6,TNF and sIL－ 2R levels of CI group were much higher than those of controls group .The variation of IL－ 6,TNF and sIL－ 2R levels was closely related to the size of cerebral infarction. The serum IL－ 6,TNF and sIL－ 2R levels of recovery period were much lower than those of acute period in patients with CI .Conclusions The IL－ 6 ,TNF and sIL－ 2R take part in the pathologic process after CI .The measurement of IL－ 6, TNF and sIL－ 2R is useful in determining the size of cerebral infarction.

Nursing students as a group of people who were going to be nurses in the future,their perceptions of pain management had closed connection with the achievements of the pain management.This review provided a summary of the nursing students' perceptions of pain management and its influencing factors,in order to make some suggestions about improving nursing education and offer effective way to improve the nurses' perceptions of pain management.

When it is cold winter in the northern China, the temperature of water is very low. Low tempera- ture is the main reason of the worse treatment of oil wastewater. In cold winter when the temperature is lowered to around 4?C, the effect of biological treatment of sewage is poor and hard to target the problem of reach a set standard of outing water. Use of microbiology to deal with oil pollution is one of the most effective, the most secure and the most thorough method. So the article from the microbiological point of view to study, isolated from nature world, screening to eight low-temperature grease which can grow under 5?C and degradation of sewage bacteria.

Astragali Radix was firstly recorded in the "Shen Nong's Herbal Classic" as a top-grade and commonly used traditional Chinese medicine. Its frequently used slices include raw Astragali Radix and honey-processed products. In current studies, many reports were made on honey-processed Astragali Radix, whereas fewer study reports were made on the cutting process of Astragali Radix. Currently, because Astragali Radix is primarily cut by drug workers according to their operating experience, but with out specific cutting parameters, it is easy to cause the loss or mildew of active ingredients. As a result, the quality of Astragali Radix circulated in the market is not guaranteed, and the quality of their slices and preparations are hard to be controlled, which seriously impact the clinical efficacy. In response, this experiment was performed, in which the optimum cutting process of Astragali Radix was taken as the study objective, the Box-Benhnken central composite design in the response surface analysis was adopted, and the content and appearance character of astragaloside and calycosin-7-glucoside were regarded as the study indicators. Three factors, namely the softening time, the drying temperature and the drying time, were selected to optimize the cutting process of Astragali Radix and obtain the optimum cutting process parameters as follows: the softening time was 3 hours, the drying temperature was 50 degrees C, and the drying time was 4 hours. According to the verification test, the Astragali Radix cutting process is steady and feasible, which has certain significance for normalizing the cutting process of Astragali Radix.

Objective:The aim of this study was to detect the P2X7 receptor (P2X7R) protein expression in pancreatic carcinoma and to analyze its association with clinicopathology features of pancreatic carcinoma.And furtherly to explore the effects and underlying mechanisms of P2X7R on invasion and migration of PANC-1 cell line.Methods:P2X7R expression was determined by immunohistochemistry in specimens of primary cancer and adjacent noncancerous tissues respectively,and analyzed the relationship between P2X7R expression and clinicopathology features of pancreatic carcinoma.The transwell assay and wound healing assay were used for investigating cell invasion and migration ability of PANC-1,and western blotting was performed to measure the expresions of MMP2 and MMP9.Results:P2X7R protein was highly expressed in both PANC-1 cell line and tumor tissue,and associated positively with the histological differentiation and lymph node staging.The active P2X7R could increase the cell migration and invasion ability of PANC-1 cell line through up-regulated MMP2 and MMP9.Conclusions:The overexpression of P2X7R plays crucial roles in the migration and invasion of pancreatic carcinoma,and may represent a novel molecular target in pancreatic carcinoma therapy.
