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.

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.

The clinical supervision of counseling and psychotherapy have a closely connection with clinical employment.Leading the way in clinical supervision,many clinical supervision models has been extrapolated by theories of various psychotherapy,relating to psychoanalysis theory,person-centered approach theory,cognitive and behavior psychotherapy theory,system theory,structuralism theory,and so on.Recently,especial,different clinical supervision models have to expand beyond psychotherapy,such as developmental model of supervision and society role model of supervision.The study has summarized clinical supervision models of the field,in order to offer literature index and concept frame.

Methods The number of publications and their cited times for the first 20 hospitals in SCI and MEDLINE, and the top 100hospitals in domestic publications in 2008 were analyzed with bibliometric analysis. Results Compared with 2007, the increased number and ratio of publications in SCI and MEDLINE for the top 20 hospitals were 1050, 51.19% and 658, 15.04%, respectively; for top 100 hospitals, the average decreased number of domestic publications was 2.08, and the number of cited publications was increased 202.52 and the increased ratio was 13.51%. Conclusions The SCI publications from top 20 hospitals increase sharply, the increase of the MEDLINE articles from the top 20 hospitals is slowly. The negative growth is showed in the number of domestic articles for the top 100 hospitals. In addition, the increase of cited articles is slowly and disproportion.

Objective To investigate the authors, the institution and endemic distribution of these authors of Chinese Journal of Orthopaedics, and understand the current situation and problems in the field of Orthopaedics. Methods The authors, the co-authors and the core authors of papers published in Chinese Journal of Orthopedics from 2005 to 2009 were quantitatively analyzed using literature search through CMCI.The distribution of institution, region and highly quantitative organization were also analyzed. Results The 1182 papers were published by the Journal within 5 years. There were 1108 papers with one or more co-authors; the cooperative rate and degree were 93.74% and 5.02, respectively. 74 papers were written by single author, which accounted for 6.26% of all papers. 615 authors (75.18% of all first authors) published only one paper. There were 295 (24.96%) papers from 67 (8.19%) core authors. 601 (50.85%) papers were from 20 high-productivity institutes.

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.
