The major target of translational medicine is the rapid application of achievements in basic research to clinical medicine. How to carry out embedded subject service for translational medicine in academic library was thus described in aspects of constructing its information service platform, establishing its service team, and deciding its service methods.

ObjectiveTo study the changes of iodine uptake of the follicular thyroid carcinoma cell line (FTC-133) and nude mice bearing human follicular thyroid carcinoma after the induction with alltrans retinoic acid (ATRA),trichostatin A (TSA) or ATRA combined with TSA.MethodsAfter the induction with ATRA,TSA,or ATRA combined with TSA in different concentrations for 96 h,the iodine uptake of FTC-133 cells was observed.The concentrations for different groups were as follows:ATRA 1.0 ×10-6 mol/L(Alow group),ATRA 1.0 × 10-4 mol/L(Ahigh group),TSA 1.65 ×10-7 mol/L(T group),Alow +T group,Ahigh +T group and ethanol (control group).Cell quantities and morphology were observed by HE staining.FTC-133 cells were subcutaneously injected into nude mice.Twelve nude mice were randomly divided into 4 groups after tumor formation:ATRA group (2 mg/kg,intragastric administration),TSA group (10 mg/kg,intraperitoneal injection),combined therapy group (ATRA + TSA,the same doses as above) and saline control group (10 ml/kg,intragastric and intraperitoneal administration,respectively).Drugs were administered to the tumor-bearing mice according to the mouse body mass daily.At the 22nd day,the tumor-bearing mice were injected with 37 MBq 131I intraperitoneally.The biodistribution of 131I and gamma imaging were performed at 4,6,12 and 24 h after the injection respectively.Histopathological examinations of the tumor samples were taken after imaging completion.The results were analyzed by analysis of variance (ANOVA) with SPSS 13.0.ResultsThe cellular iodine uptake were (23 885 ± 616.0 ) and ( 13 849 ±728.2) counts · min-1 · 10-6 cells in the Alow + T group and Ahigh + T group respectively,and the data were (985 ± 84.2) - ( 17 600 ± 782.7 ) counts · min-1 · 10-6 in the other groups ( F =600.879,P ＜0.001 ).The ％ ID/g of tumor at 6 h was 6.17 ±0.46 in the combined group and it increased to 9.34 ±0.61 at 12 h and 11.19 ± 0.98 at 24 h.The ％ ID/g of tumor in the other groups were from ( 1.97 ± 0.34)to (5.14 ± 0.65 ).The tumor qualities of the 4 groups were significantly different ( F =3.723,P ＜ 0.05 ).ConclusionThe iodine uptake of the tumor could be enhanced in the tumor-bearing mice administered with ATRA combined with TSA,a potential way for treating follicular thyroid carcinoma.

Objective To investigate the clinical value of joint detection of procalcitoninl (PCT ) ,C-reactive protein (CRP) ,and myocardial enzymes in patients with neonatal hyperbilirubinemia .Methods 30 cases of each cause were included in the study ,which were neonatal hyperbilirubinemia caused by sepsis ,pneumonia ,ABO hemolytic and breast milk jaundice .20 cases of each cause were selected including neonatal hyperbilirubinemia caused by neonatal hepatitis and low birth weight infants .All the cases involved in the study were diagnosed .30 healthy full-term newborns in the same period were recruited as control group .PCT ,CRP and myocar-dial enzymes (AST ,CK ,CK-MB ,and LDH) concentration in serum were determined .Results Compared with the control group , CRP and PCT concentration increased significantly in bacterial infected group (P< 0 .05) .Myocardial enzyme concentration in-creased significantly both in infected group and non-infected group(P<0 .05) .Among myocardial enzymes ,CK-MB concentration increased significantly in bacterial infected group ,low birth weight infants group and ABO hemolytic group(P<0 .01) and increased significantly in breast milk jaundice group and hepatitis group (P<0 .05) .AST and LDH concentration increased very significantly in hepatitis group(P<0 .01) .The specificity of PCT in bacterial infected group was significantly higher than that of CRP (P<0 .05) ,while its sensitivity was significantly lower than that of CRP in pneumonia group (P<0 .01) .Conclusion Changes of PCT , CRP and myocardial enzymes concentration are related to the occurrence and development of neonatal hyperbilirubinemia ,determi-nation of these indicators can be complementary .

Objective To evaluate the level of granzyme B mRNA and perforin mRNA in urine on the diagnosis of renal acute rejection. Methods A total of 34 cases of renal transplantation were studied.The urine samples were measured with the use of a competitive and quantitative polymerase-chain-reaction assay for granzyme B mRNA and perforin mRNA and the data were analysed by using the SPLM statistical software,mRNA levels were log-transformed. Results The levels of granzyme B mRNA and perforin mRNA in urine were higher in patients with acute rejection than in patients without acute rejection.The level of perforin mRNA in patients with acute rejection was (1.2?0.4)fg/?g of total RNA and in patients without acute rejection was (-0.6?0.3)fg/?g of total RNA (P

Air purification and disinfection are effective for the control of indoor air contaminationthe by microorganism and the improvement of indoor air quality. In this paper, the new progresses of the effectiveness of the methods for air purification and disinfection,including ventilation,ultrovialet disinfection,air filtration,chemical disinfection (ozone,formaldehyde,) are reviewed.

Objective To study the changes in tumor necrosis alpha(TNF ?), interleukin 6(IL 6), procalcitonin(PCT) and C reactive protein (CRP) levels and their values in the prediction and assisting diagnosis of infection complications in severe multiple trauma patients. Methods TNF ?, IL 6 and CRP were measured by enzyme linked immunosorbant assay(ELISA) and PCT was determined by immunoluminometric assay(ILMA) in serial samples of plasma from 34 patients with severe multiple trauma(ISS≥16) and compared with those of 11 normal control volunteers. Patients were divided into 2 groups(infection and non infection groups). The differences of the above parameters between groups were compared. In addition, all data were managed by receiver operating characteristic(ROC), and sensitivity, specificity, negative and positive predictive values for the diagnosis of infection complications were calculated. Results Plasma levels of TNF ?, IL 6, PCT and CRP in multiple trauma patients without infection complications were increased differently in the early posttrauma period. TNF ? and CRP levels in the early posttrauma period before infection were not significantly different from those in patients without infection complications, but they increased significantly following infection. However, during the whole observing period, plasma levels of PCT and IL 6 in the patients with infection complications were higher than those in patients without. The value of those parameters in assisting diagnosis of infection was evaluated. PCT was of the highest specificity and higher negative and positive predictive values. Conclusion All the parameters are of clinical value in infection diagnosis after severe multiple trauma. PCT is the best index for the prediction and assisting diagnosis of infection after multiple trauma.
