AIM: To seek for new traditional Chinese medicine(TCM) theoretical evidence for prevention and treatment of pigmentary dermopathy, and analyze relevant factors between color and effect of Chinese herb METHODS: The literatures about relevancy between color and effect of Chinese herb were reviewed, and PubMed database and the relative articles from Chinese medical journals were retrieved to analyze the relevant informationRESULTS: The holism and categorization of a thing according to its picture in Chinese traditional theory of "correspondence between man and universe" were successively employed. A great deal of literatures showed that many Chinese herbs are of marked effect on pigmentary dermopathy.CONCLUSION: Since it influences the appearance, pigmentary dermopathy greatly damages the physical and mental health of the patients. The effect of therapeutic methods and ways established nowadays cannot meet the patients demands, so the further theoretical investigation of relevancy between color and effect of Chinese herb should be done to provide theoretical evidence for clinical intervention.

Molecular biomarkers could change associated with disease processes.So,the detection of metabolic markers becomes the key to early diagnosis,treatment and prognosis evaluation disease.But the detection of abundant metabolites in body becomes a crux of laboratory medicine at the same time.The recent advances in nuclear magnetic resonance (NMR) spectroscopy reveal the unequivocal value of NMR in metabolomics platforms.NMR spectroscopy has inherently distinct capabilities to identify and quantitatively measure a large amount of low concentration metabolites in a non-destructive manner.The implementation of NMR technology into a multidisciplinary approach to biomarker identification will improve the auxiliary diagnostic ability of laboratory medicine for the disease.

BACKGROUND:Daclizumab can be special y combined with the inerleukin-2 receptor on the surface of activated T cells in human body, and this method can reflect the close of interleukin-2 receptor thus inferring the effect of induction therapy. At present, the daclizumab has been widely used in renal transplantation, but there is no consensus on its clinical application in liver transplantation. OBJECTIVE:To investigate the expression of serum CD25+T cells and soluble interleukin-2 receptor in the patients receiving daclizumab for liver transplantation during perioperative period. METHODS:A total of 58 patients received orthotopic liver transplant for the first time were included and then the patients were randomly divided into two groups:control group (n=28) and treatment group (n=30). The patients in the two groups were treated with tacrolimus, mycophenolate mofetil and corticosteroids triple immunosuppressive regimen. The patients in the treatment group received immune induction therapy with daclizumab, and the patients in the control group did not receive daclizumab. RESULTS AND CONCLUSION:Flow cytometry and enzyme-linked immunosorbent assay showed the expression levels of CD25+T cells in the treatment group were significantly lower than those in the control group at different time points after liver transplantation (P<0.01);and the expression levels of soluble interleukin-2 receptor in the treatment group were lower than those in the control group during transplantation and at the first day after transplantation (P<0.05, P<0.01). At 6 months after transplantation, the incidence of acute rejection was decreased in the treatment group (P<0.01). The results indicate that daclizumab can effectively suppress the expression level of CD25+T cells, as wel as the expression level of soluble interleukin-2 receptor in the peripheral blood in the early stage of liver transplantation, thus effectively reducing the rate of acute rejection.

Objective To construct the recombinant adenovirus encoding mouse wild type FGFR3 cDNA. Methods Mouse FGFR3 cDNA obtained from MoFR3/SV was subcloned into plasmid pBluescript KS and further cloned into plasmid pAdTrack-CMV. The plasmid (pAdTR3) was transferred into BJ5183 cells which contained the adenovirus plasmid (pAdeasy-1) to produce recombinant adenovirus vector encoding FGFR3 cDNA (pAdE-FGFR3). The recombinant adenovirus vector was identified and transfected into the adenoviral packaging cell HEK293 by lipofectamine 2000 to get recombinant adenovirus particles. The adenovirus was confirmed by polymerase chain reactin (PCR) and its titer was determined. Then the recombinant vector was transfected into HT29 cells. The expression of FGFR3 mRNA and protein in HT29 cells was assayed by RT-PCR and Western blotting. Results The recombinant adenovirus vector encoding FGFR3 cDNA was correctly constructed and confirmed by restriction endonuclease analysis and DNA sequencing analysis. The transfected HEK 293 cells were lysed by freeze-thawing to obtain the recombinant adenovirus in the lysate. Further, PCR product of the lysate confirmed the presence of recombinant adenovirus. The viral titer was 3?109pfu/ml. RT-PCR and Western blotting showed that pAdE-FGFR3 transfected HT29 group expressed FGFR3 higher than that of GFP controlled group. Conclusion Infective recombinant adenovirus encoding FGFR3 cDNA was successfully obtained by plasmid homogenous recombination in bacteria, and highly expressed in HT29 cells after transfection, which paves a way for studying the effect of FGFR3 in bone fracture healing.

Objective To survey the state of internet addiction of vocational college students and explore the effect of perceived social support and loneliness on Internet addiction.Methods In accordance with random cluster sampling,this research used the Revised Chen Internct Addition Scale,Perceived Social Support scale,and UCLA Loneliness Scale to study lnternet addiction among a total of 1 602 vocational college students from three higher vocational colleges in Guangzhou.Results [nternet addiction rate was 9.87％,and Internet dependence rate was 24.78％.Internet addiction had a higher incidence rate among male students than that among female students (x2=19.775,P＜0.01).The perceived social support group of vocational college students was low,which indicated serious loneliness based on the Loneliness Scale,and their scores on Internet addiction tendency were higher than those of other groups (P＜0.01).The total scores in Internet addiction tendency and perceived social support were negative (r=-0.183,P＜ 0.01),which indicates positive correlation with loneliness (r=0.243,P＜ 0.01).The mediating effect of perceived social support and Internet addiction on loneliness was significant,with a mediation rate of 69.63％.Conclusion Internet addiction tendency of vocational college students is a problem that deserves more attention.Low social support and loneliness can increase the incidence rate of internet addiction tendency.Loneliness is also found to be a strong predictor of internet addiction.

Objective To observe the effect of endothelin-1 (ET-1) on the cell growth, adhesion, migration and expression of intercellular adhesion molecule 1 (ICAM-1) by A375 human malignant melanoma cells. Methods A375 cells were cultured in the presence of ET-1 of various concentrations (0.002, 0.02, 0.2, 2 μg/mL) for different periods. MTT method and flow cytometry were applied to detect the proliferation and ICAM-1 expression of these cells, respectively, after 24-, 48-, and 72-hour treatment. After 24-hour treatment, the cell adhesion and migration of A375 cells were assessed with cell adhesion assay and Transwell chambers, respectively. Results In the case of ET-1 from 0.002 to 0.2 μg/mL, it enhanced the proliferation, adhesion, migration of A375 cells and inhibited the expression of ICAM-1 by A375 cells in a dose dependent manner (P<0.01 or<0.05); however, for ET-1 of 2 μg/mL, the situation was the opposite. Moreover, after 24-hour culture with ET-1 of 0.2 μg/mL, the metabolic activity, cell adhesion rate, and expression of ICAM-1 peaked at 0.327±0.009, (163.31±4.05)% and 4.667±0.551, respectively. Conclusion ET-1 may enhance cellular metabolism and pigmentation by suppressing the expression of ICAM-1 and promoting the proliferation, adhesion and migration of melanoma cells.

Objective To study the anatomical relationship between the umbilicus and the retroperitoneal major vessels. Methods A total of 80 female patients undergoing laparoscopy in our department were enrolled in this study. The patients were divided into 4 groups according to their body mass index (BMI):low-weight group,normal-weight group,overweight group,and obese group. During the operation,the surgeons palpated the abdominal aorta,right common iliac artery,and left common iliac artery with hand to determine their relationship to the umbilicus. The abdominal aortic bifurcation was used as a reference point to determine its position in relation to the umbilicus. Results (1) The bifurcation was above the level of the umbilicus in 17 (21.2%) cases,at the umbilicus level in 29 (36.3%) cases,and below that in 34 (42.5%) cases. Among the four groups,the position of the bifurcation was significantly different (?2=16.769,P=0.010). In the overweight and obese groups,most of the patients had the umbilicus located under the level of the aortic bifurcation [65.0% (13/20) and 75.0% (6/8) respectively],while in the normal-weight group,47.6% (20/42) of the cases had the umbilicus above the aortic bifurcation(P
