Objective: Our aim was to evaluate the biocompability of porcelain compounded with nanostructured material. Methods:The proliferation of the NIH3T3 cells were investigated using a tetrazolium-based colorimetric assay(MTT assay).Maceration extract of four tested materials were added into culture plate .The samples were tested with ultraviolet spectrophotometer in 490 wavelength at 1,3,5,7 days after the addition of extract. Morphology of these cells was also observed with phase-contrast microscope. Results: There was no obvious difference among three kinds of prosthetic materials in the optical absorbance and the cells growing in the extract showed normal morphology. Conclusion: The toxicity graduation of the porcelain compounded with nanostructured material is 0. This material has a good biocompability and can be used clinically.
2.Neoadjuvant therapy of liver metastases form colorectal cancer
International Journal of Surgery 2009;36(11):773-776
With the development of peaple's life and the change of diet,the incidence rate of colorectal cancer is increasing. There are Twenty-five percent of patients were found liver metastases in the first diago-sis. Surgical resection of liver metastases from colorectal cancer is known to be associated with long term sur-vival. So it is the key to increase the resection rate for colorectal cancer patients with liver metastases. The in-curruence of neoadjuvant therapy may be useful in therapy of colorectal cancer patients with liver mtastases.

5.The expression of Fas antigen in hemangioma and vascular malformation.
Journal of Practical Stomatology 1995;0(04):-
Objective: To investigate correlation between the expression of Fas antigen in hemangioma and vascular malformation.Methods: Anvidin-biotin complex immunohistochemical method was used to detect the expression of Fas antigen in 31 cases hemangioma and 10 cases of vascular malformaton. Results: The expresson of Fas antigen was positive in hemangioma and negative in vascular malformation. Conclusion: The expression of Fas antigen might be related to the natural involution of hemangioma.
6.MicroRNAs and epithelial mesenchymal transition in cancer
Journal of International Oncology 2014;41(12):881-884
In recent years,a lot of researches have shown microRNA (miRNA) involved in every link of epithelial-mesenchymal transition(EMT) regulation process through a variety of signaling pathways in tumor; even the same kind of miRNA plays significantly different roles in different tumors,inducing great significance to guide clinic.

Though there is a great progress in research of medical ethics in China, a gap still remains between China and the developed countries now. Medical ethics committees are established one after another in many hospitals, but the level of standardization construction and ethical review level differ in thousands ways. The construction of ethical review platform on TCM can standardize the construction and investigation procedure, and can further enhance the ethical review level of medical ethics committee. Among them, institutional improvement of regulations and procedures can be acquired in short time, but the enhancement of ethical review level needs a long way to go. This article aimed to probe the thinking and methods on the enhancement of ethical review level through the practice and experience of the construction of TCM ethical review platform.

Glucagon-like peptide 1(GLP-1) is an important member of incretin.Takingitoralymay stimulate the terminal ileum and colon L cel s to secrete GLP-1. After GLP-1 biding specific receptor GLP-1 receptor ( GLP-1R), it exerts the roles of promoting glucose-dependent insulin secretion, inhibiting glucagon secretion, and decreasing plasma glucagon level. The molecular mass of GLP-1 is relatively smal er and can directly cross the blood-brain barrier, and both central and peripheral nervous systems have the GLP-1R expression. GLP-1 significantly improves neurological deficits and reduces infarct volume. It may exert neuroprotective effect through the mechanisms of inhibiting the inflammatory response, oxidative stress, and cel apoptosis. This article review s the discovery of GLP-1, its biological characteristics and neuroprotective effect in cerebral ischemia.

Objective To discuss two simulation studies on the closed and open peritoneum in abdomenal operations. Meth-ods We selected 120 domestic female rabbits from animal laboratory of Qi Qi Ha’er Medical College at random and divided them into four groups(according to whether the peritoneum was open or not,the degree of peritoneum defect at the right side of incision and the existence of peritoneum hemorrhagic focus ),with 30 cases in each group. Group Ⅰ: no peritoneum suture and making a defect of 4cm?3cm at the right side of the incision; Group Ⅱ: no peritoneum suture and making a defect of 4cm?3cm at the right side of the incision,with a hemorrhagic focus at peritoneum defect;Group Ⅲ: with peritoneum suture; Group Ⅳ:with dense and compact peritoneum suture.And then we analyzed postoperative peritoneum healing progress. Results Observeations of the incision infection by the naked eye were that one case was identified in group Ⅰ,Ⅲ and Ⅳ;and a significant difference of occurrence rate was identified between the fallowing groups: groupⅠandⅡ(P

Objective To investigate the effect of valsartan and amlodipine on urinary microalbumin in elderly hypertensive patients. Methods 100 elderly patients with hypertension treated in our hospital from May 2015 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The patients in the control group received oral valsartan, and the patients in the experimental group were treated with valsartan and amlodipine. The treatment time of the experimental group and the control group was 12 weeks. The clinical indexes of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the experimental group and the control group did not have obvious adverse reactions. There were 2 cases of headache in the experimental group, 1 cases of vertigo, and 2 cases of vertigo in the control group. However, there was no significant difference in the incidence of adverse reactions between the experimental group and the control group, and there was no statistical significance. The antihypertensive effect of the experimental group was significantly higher than that of the control group, with statistical significance (P<0.05). After treatment, the urinary microalbumin in the experimental group and the control group was significantly lower than that in the treatment group, and the level of microalbuminuria in the experimental group was lower than that in the control group, with statistical significance (P<0.05). Conclusion The clinical effect of treatment of elderly patients with hypertension better combined with valsartan and amlodipine, antihypertensive effect is stronger, can significantly improve the patient's urinary albumin, with further clinical promotion and application significance.
