There exists different view in the goal of investigative study.Based on the self-fulfilling cycles of self-regulated learning,the author of the article puts forward that developing the ability of self-regulated learning by doing investigative study according to each phase characteristic of self-regulated learning is one of the important goals of investigative study.

The increase of blood-brain barrier (BBB) permeability is a key link in causing the pathological changes in vasogenic brain edema and inflammatory reaction. In recent years, a number of studies have indicaded that a lot of mediators participated in the structural and functional changes and damage of BBB during the process of cerebral ischemia-reperfusion.

C.Conclusion: The drug releasing rate of Icariin Ointment made of emulsion ointment base is the fastest.

Objective To report successful nursing experience of cardiac arrest caused by amniotic fluid embolism.Methods 3 pregnant women with cardiac arrest caused by amniotic fluid embolism from January to August 2012 were successfully rescued,the nursing measures included observation of labor course,mechanical ventilation,rapid establishment of intravenous injection route,anti-shock and prevention of DIC and renal failure.Results 3 cases of pregnant women were given timely rescue and pulled through.All rehabilitated and were discharged.Conclusions Amniotic fluid embolism is the most serious,dramatic,and the most difficult to control complications in obstetric department.Prevention is the key for amniotic fluid embolism,once happened,medical workers should carry out rescue work calmly and implement effective interventions.

To study the initiatives and progress of African nations in promoting the development of traditional medicine to determine if these measures can be applied to the protection of traditional Chinese medicine knowledge. Information research methods were used to collect and analyze relevant literature. The development of African traditional medicine has been effectively promoted through various measures taken by African organizations and governments. In recent years, Africa has achieved remarkable results in promoting the development of traditional medicine. Many other countries will benefit from studying their examples and adopting similar measures.

Objective To observe the correctly positioning rate of left-sided double lumen endobronchial tube by combined adjustment of auscultation,PETCO2 and airway pressure changes.Methods Sixty adult patients undergoing thoracic surgery were intubated with Robertshaw DLTs. DLT position is checked and adjusted by fiberoptic bronchoscope（FOB）. Results In the supine position,successful intubation is 57 cases by three combined methods,one of cases is shallower,two of cases are deeper,satisfactory rate is 95 percents;In the lateral decubitus position,successful intobution is 56 cases by three combined methods,two of cases is shallower,two of cases are deeper,satisfactory rate is 93.4 percents.Conclusion Three combined methods that are simple,reliable can be used repeatedly during postural changes without increasing the opportunities for injury,it is clinically a very good approach,but the absolute scope of safety is very small,FOB is necessary for positioning.

Objective To study the significance of Wnt5a gene expression in gastric carcinoma (GC). Methods The Wnt5a mRNA expressions in SGC7901 cell line and normal gastric mucosa GES-1 cell line were detected by RT-PCR. The Wnt5a protein expressions in 60 GC and 30 matched tumor-adjacent normal tissue samples were examined by immunohistochemistry using the streptavidin-peroxidase method.χ2 test was used to analyze Wnt5a expression on the clinical pathologic features of gastric carcinoma. Results Both Wnt5a mRNA and Wnt5a protein were significantly higher in SGC7901 cells than those in GES-1 cells. The positive rate of Wnt5a protein expression was also significantly higher in GC than that in tumor-adjacent normal tissue (P < 0.05). Positive expression of Wnt5a was associated with higher degree of regional lymph node metastasis and the later TNM stage (P < 0.05). Conclusion Higher expression of Wnt5a seems to promote invasion and metastasis of gastric cancer, and Wnt5a might play an oncogene-like role in the development of gastric carcinoma.

A case of pyogenic granuloma occurred in inferior turbinate was reported and the literatures were reviewed. A 32 years old male patient with left side progressive stuffy nose and repeated epistaxis. Nasal endoscopic examination showed a dark red neoplasm in left nasal cavity and blocked the anterior naris. Nasal cavity enhanced CT showed the neoplasm located in the front of left nasal cavity with marked enhancement. Bilateral sinuses were normal and there was no significant bone destruction. Nasal endoscopic surgery was performed under local anesthesia. Postoperative pathology report showed pyogenic granuloma (granulation tissue type of angioneoplasm).

With the deepening of the study on traditional Chinese medicinal quality and the rising requirements of TCM quality control, the demand of setting TCM quality were emphasized,as well as higher education course. Surrounding the purpose of exploring the related issues of the traditional Chinesemedicinal courses setting and promoting the college curriculum innovation capability,the paper mainly discussed the course open orientation, the teaching characteristics, objectives, idea, the core content and the training scheme, as well as the plan of course and teaching material construction depended on these contents.

Objective To analyze the distribution characteristics and drug resistance change of acinetobacter baumannii in prima‐ry hospital during 2005-2014 to provide reference for clinical rational drug use .Methods The infection characteristics of acineto‐bacter baumannii in primary hospital during 10 years and its resistance to 10 kinds of common antibacterial drugs was analyzed .Re‐sults A total of 576 strains of acinetobacter baumannii were isolated during 2005-2014 ,accounting for 31 .44% of all Gram nega‐tive bacteria ,which was significantly higher than that of Escherichia coli ,pseudomonas aeruginosa and klebsiella pneumonia bacillus (P<0 .05);446 strains were mainly originated from the sputum specimens (77 .43% ) and 290 strains(50 .35% ) from ICU ;the re‐sistant rate was 44 .44% for CSL ,62 .24% for MIN and more than 70 .00% for 8 kinds of antibacterial drugs of IPM ,MEM ,etc .;which to IPM ,CAZ ,SXT showed the declining trend year by year ,while which to MEM ,AMK ,LEV ,MIN showed the rising trend year by year .Conclusion The isolated acinetobacter baumannii strains in primary hospital are rised year by year ,and generally have resistance to commonly used antibacterial drugs ,the clinical doctors should rationally select antibacterial drugs according to the drug susceptibility test results for preventing the occurrence of acinetobacter baumannii infection .
