Basic & Clinical Medicine 2006;0(02):-
Protein fingerprinting technology(PFT) is a novel technology for laboratory diagnosis developed in recent five years.It has advantages of simple operation,testing quickly,high sensitivity and specificity.It is a revolutional progress for laboratory diagnosis.The application of PFT in medical field is mainly for the detection of diseases.The sensitivity and specificity in cancer detection are about 80%.Immunomic mass spectrometry(IMS) is a novel technology using the combined group antibodies for capture multi biomarkers and applying mass spectrometry to precisely analyze the modification or isoforms of the biomarker in single platform,whereas traditional assay could not be able to identify the variation of biomarkers.PFT and IMS have significantly influenced in cancer early detection,especially to evaluate cancers which did not express traditional tumor markers like AFP,CEA,etc.PFT and IMS have characteristics of early detection in the molecular and gene level.PFT and IMS are diagnostic technologies with bright future and potential applications.
2.Effects of Cisplatin on Proliferation and Invasion of Colorectal Cancer Cells
Tianjin Medical Journal 2014;(7):638-640
Objective To investigate the effect of cisplatin on proliferation and invasion of colorectal cancer cell line SW480. Methods SW480 cells were used as the research object, and untreated SW480 cells were used as the control group. Different concentrations of cisplatin was given at different times to intervene. The MTT, Transwell chamber and phos-phate determination methods were used to detect proliferation, invasion and Na+-K+-ATPase activity expression level in SW480 cells. Results The physiological concentration of cisplatin (70 μmol/L) inhibited the proliferation of SW480 cells at 48 h. There was no significant difference in the inhibition rate at 48 h compared with 72 h and 96 h. Treatment with 70 μmol/L cisplatin for 48 h reduced the number of cells through Matrigel membrane matrix. The Na+-K+-ATPase activity was significantly increased in 35, 70 and 140 μmol/L cells after treatment with 17.5, 35, 70 and 140 μmol/L of cisplatin in SW480 cells for 48 h, and Na+-K+-ATPase reached the highest level at 70 μmol/L of cisplatin. Conclusion The decreased activity of Na+-K+-ATPase may lead to the attenuation in proliferation and invasion of colorectal cancer cells, which may be associated with cisplatin resistance in colorectal cancer cell SW480.

5.The reliability study of urinary microalbumin test by dry hemical method
International Journal of Laboratory Medicine 2009;30(3):229-231
Objective The quantitation measurement of microalbuminuria was adopted to verify the feasibility of urinary microalbumin and ratio of mieroalbumin to creatinine (M/C) detection with dry hemieal method. Methods Totally 80 urine samples from the patients with clinically diagnosed dia-betes were tested by the immune quantitation method (immunoturhidimetric assay) and dry heroical method (HT2000 urine analyzer and test paper, Guilin Hnatong Company) simultaneously. Sarcosine oxidase method was applied to measuring creatinine level. Ten cases of outliers were removed. With the quantitation result of M/C as the reference standard, immune quatilyzation of the M/C as refer-ence, we compared and analyzed the results of the immune quantilization of urine microalbumin, those of the dry chemistry method and of the dry chemistry system detecting M/C. Results There was sig-nificant differences in test results of urinary microalbumin with the dry chemistry method and the im-mune quantitation method (P<0.01) The sensitivity, accuracy and Youden index of the microalbu-minuria testing had been observed to decrease in order in immune the dry chemistry method, the im-mune quantitation method and M/C quantitation detection method. Conclusion The sensitivity of semi-quantitation dry chemical method is satisfactory in detecting microalbumin, which may be used as a means of microalbumin screening. M/C detection with the dry chemical method isn't suitable for screening microalbumin in instant urine samples.

8.Differentiation of adult bone marrow mesenchymal stem cells into islet-like cells in vitro
Chinese Journal of Tissue Engineering Research 2007;0(08):-
BACKGROUND: In recent years, there are some effects on using pancreatic islet cell or pancreas transplantation in the treatment of diabetes. But there are still two major problems: lack of donor and immune rejection. Mesenchymal stem cells can be induced to islet-like cells in vitro. OBJECTIVE: To study the progress in the differentiation of insulin secretion cells induced by mesenchymal stem cells. RETRIEVAL STRATEGY: A computer-based online search of Pubmed was undertaken for the related English articles dated from August 1997 to August 2007 with the of "mesenchymal stem cells,insulin secreting cell". At the same time, we searched China Journal Full-Text Database for the related Chinese articles published between August 1997 and August 2007 with the same key words. Total retrieved 108 literatures which are firstly selected into the inclusive criteria: ①The articles focusing on the mesenchymal stem cells induced differentiation into insulin secreting cells. ②choose articles at the same field or published in authoritative magazine published in the recent time. Exclusive criteria: ①Repeated experiments or ②Meta analysis articles. LITERATURE EVALUATION: All the literatures are about the differentiation of insulin secretion cells induced by bone marrow mesenchymal stem cells. Of the 30 selected literatures, 2 are reviews and the others are clinical or basic experiment study. DATA SYNTHESIS: ①Because the pancreas is similar to the nervous system in the mechanism of development and control, now people think that nerve growth factor may be the key signal to the pancreas development. Mesenchymal stem cells have an ability of multi-differentiation; it can be induced into nestin positive cells by using epidermal growth factor and basic fibroblast growth factor. Mesenchymal stem cells will be further induced to pancreatic cells if we add conditioned medium as the appropriate micro-environment for islet cells. ②Now identification and functional study of insulin-like cells are for the following areas: observe whether there is islet-like cells group gathered by cell morphology; test insulin, glucagons and somatostatin expression after induction; test insulin and glucagons gene expression using RT-PCR method after induction; to study the function of induced pancreatic cells by using glucose-stimulated insulin release test. CONCLUSION: As the research about mesenchymal stem cells can be induced islet-like cell in vitro becoming ever-changing technology, it becomes a new program of cell therapy to diabetes in face of all problems. According to all the present experimental results, the insulin secretion of induced pancreatic islet cells is much smaller than the normal amount of insulin secretion. Therefore, how to induce efficiently with human physiology of islet cell in vitro and then transplant safely into the human body will bring a new leap of diabetes treatment.

10.Differentiation of human bone marrow mesenchymal stem cells into osteoblasts in vitro
Chinese Journal of Tissue Engineering Research 2007;0(38):-
BACKGROUND: Cells grew slowly in a low number after conventional induction. Growth factor can accelerate induction speed, but growth factor is expensive. OBJECTIVE: To verify the efficiency of differentiation of human bone marrow mesenchymal stem cells (BMSCs) into osteoblasts in vitro in a inductor without growth factor. DESIGN, TIME AND SETTING: The control cytology observation experiment was conducted from July 2007 to February 2008 at the Center Laboratory of Hospital Affiliated to Medical College of Qingdao University. MATERIALS: Bone marrow was collected from diabetic patients undergoing autologous stem cell transplantation. Informed consent was obtained from patients. METHODS: Using density gradient method, BMSCs were separate and primary cultured. At the third passage, BMSCs were incubated in 0.1 ?mol/L dexamethasone, 10 mmol/L ?-glycerine sodium, and 50 ?mol/L vitamin C. BMSCs in the control group were left intact. MAIN OUTCOME MEASURES: Morphology of BMSCs was observed under a phase contrast microscope. Morphological changes were measured by alkaline phosphatase staining and calcified nodules staining after induction. RESULTS: Under the phase contrast microscope, the third passage of BMSCs was uniform, spindle. At 7 days, cells were confluence. Some cells were overlapped over time. Mesenchymal tissues gradually piled up, with mineralization, multiple nodes. At 14 days, brown mineralized nodes were found under an inverted microscope. At 21 days, mineralization in fragmentis were formed. Von Kossa method demonstrated black calcified nodules and positive alkaline phosphatase. CONCLUSION: BMSCs can be induced into osteoblasts easily, with high and rapid proliferation.
