Objective:To investigate the role of interleukin-10 (IL-10) and IL-12 in the differential diagnosis of tuberculous and malignant pleural effusion through measuring the serum and pleural effusion IL-10 and IL-12 levels of tuberculous and malignant pleural effusion patients.Methods: Forty-eight inpatients with exudative pleural effusion who didn''t receive any treatment before were selected.According to the pathogeny, the patients were divided into tuberculous pleural effusion group (n=25) and malignant pleural effusion group (n=23).The levels of IL-10 and IL-12 in peripheral blood and pleural effusion of the patients in two groups were detected by Cytometric Bead Array (CBA).The differences in IL-10, IL-12 levels and IL-12/IL-10 ratio were compared between two groups.The ROC curves of the above indexes, cast-off and adenosine deaminase (ADA) were used to compare the effects in differential diagnosis of tuberculous and malignant pleural effusion.Results: There were no statistical differences in the levels of serum IL-10, IL-12 and IL-12/IL-10 ratios of the patients between tuberculous and malignant pleural effusion groups (P>0.05),and the IL-12 level in pleural effusion and the IL-12/IL-10 ratio of the patients in malignant pleural effusion group were lower than those in tuberculous pleural effusion group (P<0.005).The area under the ROC curve for the levels of IL-12 in pleural effusion (0.984) was higher than those for the ratio of IL-12/IL-10, cast-off and ADA (0.744, 0.804 and 0.911, respectively) in the differential diagnosis of tuberculous and malignant pleural effusion.Conclusion: The detection of IL-12 levels in pleural effusion is helpful for the differential diagnosis of tuberculous and malignant pleural effusion, and the pleural effusion is easy to obtain, therefore the detection of IL-12 in pleural effusion is worth to be widely applied in clinic.

Objective:To investigate the relationship of expression of vascular endothelial growth factor (VEGF) and clinical features in patients with intracranial aneurysm and arteriovenous malformation (AVM).Methods:A total of 64 patients with AVM and intracranial aneurysm,who were treated in First Hospital of Shijiazhuang from February 2011 to November 2015,were chosen as research subjects,AVM were 32 cases and intracranial aneurysm were 32 cases.The samples were sectioned for VEGF immunohistochemical staining;the location and intensity of staining were recorded;the positive indexes were computed.The VEGF expression of different age and Hunt&Hess classification in patients with intracranial aneurysms were analysed;the VEGF expression of different diameters,ages,Spetzler classification in patients with AVM were analysed.Results:There were no statistical differences in the VEGF expression of different ages in patients with intracranial aneurysms (P＞0.05);the VEGF expression of different Hunt&Hess classification in patients with intracranial aneurysms was statistical difference (P＜0.05).The positive rate of VEGF in the artery of AVM was lower than that in the vein,the difference was statistically significant (P＜0.05).There were no statistical differences in the VEGF expression of the different Spetzler classification,different diameters and different ages in patients with AVM (P＞0.05).Conclusion:The expression of VEGF in the vein and the artery of patients with AVM is different,the expression of VEGF is not correlated with the age of intracranial aneurysm and the size and age of AVM.VEGF cannot be used as a predictor in the patients with intracranial aneurysms and AVM.

Objective To investigate the chang and impaction of TM and D- Dimer on peripherally inserted central catheter (PICC) associated thrombosis in cancer patients. Methods The expression of TM and D-Dimer from 207 cancer patients with PICC was examined using nzyme-linked immunoassay. Paitents were divided into thrombosis group and control group according to Doppler Sonography. Results The thrombosis group had 33 cases and the control group had 174 cases in 207 malignant tumor patients with PICC. Compared with that in control group, the expression of TM (6.806 ± 1.805)μg/L and D-Dimer (0.786 ± 0.294) mg/L was significantly higher in thrombosis group and respectively statistically significant (P<0.05), The expression of TM and D-Dimer was positively correlated with thrombosis respectively (r=0.572 and 0.530, P<0.05). The multi-factor Logistics analysis showed the odd ratio of TM was 1.899 and the odd ratio of D-Dimer was 7.292, and the difference was statistically significant (P<0.05). Patients were dichotomized into elevated and noneelevated groups according to the 50th percentile of the levels of TM and D-Dimer of the total study population. In multivariable analysis, the odd ratio of both elevated TM and elevated D-Dimer was 2.04, which was higher than elevated TM (1.286) alone and elevated D-Dimer (1.044) alone, and there was difference in statistics (P<0.05). The results showed that the risk of PICC associated with thrombosis in both elevated TM and elevated D-Dimer TM increased 2.042 times. The expression of TM and D-Dimer was correlated with clinical stage respectively (r=0.477 and 0.492, P<0.05);but was not correlated with age, sex, site of tumor and concurrent radiochemotherapy (P>0.05). Conclusions The expression of TM, D-Dimer is elevated, which is expected to assess the early diagnosis and clinical value of PICC associated thrombosis in cancer.

Objective:To explore the correlation between serum level of matrix metalloproteinase 2 (MMP-2)and se-verity of coronary artery disease in aged patients with acute coronary syndrome (ACS)complicated hyperhomocys-teinemia (HHCY).Methods:According to serum level of homocysteine (Hcy),a total of 105 aged ACS patients were selected and divided into ACS+HHCY group (n=56)and pure ACS patients (n=49),another 65 healthy in-dividuals were enrolled as healthy control group.The severity of coronary artery disease was showed by Gensini score ;enzyme linked immunosorbent assay was used to measure serum MMP-2 level in each group.Results:Com-pared with healthy control group,there were significant rise in MMP-2 level [(140.8±50.1)ng/ml vs.(442.5± 98.2)ng/ml,(297.9±86.3)ng/ml]in ACS+HHCY group and pure ACS group,P <0.01. Gensini score in ACS+HHCY group was significantly higher than that of pure ACS group [(1.9±0.2)scores vs.(1.1±0.3)scores,P<0.01].Pearson correlation analysis indicated that Gensini score was positively correlated with MMP-2 level in ACS+HHCY group (r =0.424,P <0.05).Conclusion:The serum MMP-2 level is significantly positively correla-ted with severity of coronary artery disease in aged patients with ACS complicated HHCY.

Model-informed drug development (MIDD) in the development of pediatric drugs is drawing more and more attention due to the insufficiency of subjects, lack of research on ontogeny, and the limitation of ethic. The core of MIDD used for dose selection includes the population pharmacokinetic (PopPK) model and physiologically based pharmacokinetic (PBPK) model, as well as model-based simulation and prediction. PBPK model has the advantage of predicting the optimal pediatric dose before the clinical trials and has the ability of extrapolation from adult model to pediatric model. PopPK model characterizes the pediatric PK feature based on the analysis of clinical data and can be used to explore the significant covariates, which is a power tool for individualized medicine in children. With their own advantages and disadvantages, PBPK and PopPK model should be jointly used in the pediatric drug development to refine the dose regimen for children at different ages. In this study, the pediatric drug development of rivaroxaban was taken as an example to introduce the combined application of PBPK model and PopPK model in the design and validation of pediatric dose regimen in Phase Ⅰ, Ⅱ and Ⅲ trials, which may provide reference to MIDD in other pediatric drug development.

ObjectiveTo evaluate the effect of the timed “up and go” test (TUGT) on measuring functional mobility of stroke patients.MethodsNinety hemiparetic stroke patients participated in this study. The balance, gait speed and disability of patients were measured by Berg balance scale (BBS), maximal gait speed and functional independence measure (FIM) to find out the critical value of TUGT.ResultsA good relationship existed among TUGT and the BBS,gait speed and FIM (r=-0.926—-0.674,P<0.001).The percentage of independent walking of stroke patients whose TUGT scores <10s or>20s were 100% and 8.3%. The optimal cut off values of TUGT to predict the independent walking of patients were 15.2s, and in stroke group sensitivity and specificity of TUGT were 89.4% and 79.1%.Conclusion TUGT is a reliable instrument with adequate concurrent validity to measure the functional mobility of stroke patients.

Objective To explore the effects of NF-E2-related factor 2 (Nrf2) overexpression on mitochondrial biosynthesis and function in melanocytes.Methods An immortalized human vitiligo melanocyte cell line PIG3V was used in this study.An overexpression plasmid Nrf2-pEX-1 containing the full-length Nrf2 gene was constructed.PIG3V cells were divided into 3 groups:blank group receiving no treatment,control group transfected with the pEX-1 plasmid,overexpression group transfected with the Nrf2-pEX-1 plasmid.After transfection,real-time quantitative reverse transcription-PCR (RT-PCR) and Western blot were performed to determine the mRNA and protein levels of mitochondrial biosynthesis-related factors (including Nrf2,nuclear respiratory factor 1 (NRF1) and mitochondrial transcription factor A (TFAM)) respectively;RT-PCR was also conducted to measure the copy number of mitochondrial DNA (mtDNA),and flow cytometry to estimate mitochondial membrane potential (MMP);luciferase reporter system was used to estimate the intracellular adenosine triphosphate (ATP) level.Statistical analysis was carried out by using a two-sample t-test.Results After transfection,a significant increase was observed in the mRNA expression levels of Nrf2 and NRF1 at 24 hours (both P ＜ 0.001) and in those of Nrf2 and TFAM at 48 hours (both P ＜ 0.05),but no significant change was noted in the mRNA expression level of TFAM at 24 hours (P ＞ 0.05) or in that of NRF1 at 48 hours (P ＞0.05) in the overexpression group compared with the control group.In the case of Nrf2,NRF1 and TFAM protein levels,the overexpression group showed significant increases compared with the control group at 48 hours after transfection (all P ＜ 0.05),while no significant difference was noted between the two groups at 24 hours.Compared with the control group,MMP in the overexpression group increased by 2.313％ at 24 hours (t =5.546,P =0.005) and by 14.872％ at 48 hours (t =8.537,P =0.001) after transfection.Both the relative copy number of mtDNA and ATP level were similar between the overexpression group and control group at 24 hours after transfection (both P ＞ 0.05),but significantly higher in the overexpression group than in the control group at 48 hours (t =5.760,P =0.005;t =22.040,P =0.008).Conclusion Up-regulation of Nrf2 pathway can improve mitochondrial function and biosynthesis in PIG3V cells likely by promoting the expressions of mitochondrial biosynthesis-related genes and proteins.

CC chemokine receptor 4 (CCR4) is a kind of G-protein-coupled receptor, which plays a pivotal role in allergic inflammation. The interaction between 2-(2-(4-chloro-phenyl)-5-{[(naphthalen-1-ylmethyl)-carbamoyl]-methyl}-4-oxo-thiazolidin-3-yl)-N-(3-morpholin-4-yl-propyl)-acetamide (S009) and the N-terminal extracellular tail (ML40) of CCR4 has been validated to be high affinity by capillary zone electrophoresis (CZE). The S009 is a known CCR4 antagonist. Now, a series of new thiourea derivatives have been synthesized. Compared with positive control S009, they were screened using ML40 as target by CZE to find some new drugs for allergic inflammation diseases. The synthesized compounds XJH-5, XJH-4, XJH-17 and XJH-1 displayed the interaction with ML40, but XJH-9, XJH-10, XJH-11, XJH-12, XJH-13, XJH-14, XJH-3, XJH-8, XJH-6, XJH-7, XJH-15, XJH-16 and XJH-2 did not bind to ML40.Both qualification and quantification characterizations of the binding were determined. The affinity of the four compounds was valued by the binding constant, which was similar with the results of chemotactic experiments. The established CEZ method is capable of sensitive and fast screening for a series of lactam analogs in the drug discovery for allergic inflammation diseases.
