Objective To explore the role of monitoring the cellular immune function in preventing and treating the fungal infection in the recipients of liver transplantation. Methods 679 cadaveric liver transplantations (from Jan. 2004 to Jan. 2010) were retrospectively studied. All the cases were divided into 3 groups according to different treatments and preventing regimens. The patients in groups A, B, C were treated based on the clinical experiences (394 cases), T lymphocyte subsets counting (151 cases), and combination of ATP values of CD4+ T cell and T lymphocyte subsets counting (134 cases), respectively. The infection, mortality and acute rejection rate were analyzed. The relationship between fungal infection and cellular immune function was investigated.Results The fungal infection rate in groups A, B, and C was 28. 9 %, 21.2 %, and 19. 4 % (P<0. 05), the morbidity rate was 16. 7 %, 12. 5%, and 3. 8% (P>0. 05), and the acute rejection rate was 28. 4 %, 17. 2 %, and 13. 4 % (P<0. 01), respectively. The CD4+ T lymphocyte counting in all cases of fungal infection was (147±43)×106/L. The morbidity could reach 50. 0 % when the CD4+ T lymphocyte counting < 100 ×106/L, while it was 2. 4 % when the counting was between (100-200) ×106/L (P<0. 01). The CD4+ T lymphocyte counting had no linear relation with the ATP value.The ATP value in fungal infection cases was (117 ± 61)μg/L. Conclusion The cellular immune function test could be quantitatively evaluated according to the T lymphocyte subsets and ATP value of CD4+ T lymphocyte. And individualized immunosuppressive therapy could be adjusted accordingly.Therefore, cellular immune function could be instructive in preventing and treating the fungal infection after liver transplantation.

Epithelial-mesenchymal transition (EMT) refers to tne transition during which epithelial cells undergo the loss of apical-basal polarity, acquisition of migration capability and transformation into mesenchymal cells. EMT induces breast cancer in situ to developing into metastasis and associates with the drug resistence. The multiple elements including signal pathways, transcriptional factors and downstream genes orchestrate the transition. Among them, the transforming growth factor β (TGF-β) signaling pathway plays a key role in the regulation of EMT in breast cancer. And this paper reviews the development of TGF-β signaling pathway induced EMT in breast cancer.

42 cases of OSCC and 20 of healthy tissues were studied to detect the expression of NIMA-related Kinase 2(NEK2)mRNA by Real-time PCR.Over expression of NEK2 mRNA was observed in OSCC (z =-6.328,P <0.05),the expression was correlated with the differentiation (z =-5.012,P <0.05)and clinical stage (z =-4.950,P <0.05)of the lesion,but not with the lymph node metastasis (z=-0.051,P >0.05),age (z =-0.365,P >0.05)and gender (z =-3.450,P >0.05).NEK2 gene may be involved in the develop-ment of OSCC.

Purpose To investigate the clinical value of MR PROSET technique in showing and diagnosing in lumbarsacral nerve root diseases.Materials and Methods Conventional MRI sequence and PROSET sequence coronal images were performed in lumbosacral nerve roots of 15 healthy volunteers and 47 low back pain patients,each case performed 3D maximum intensity projection (3D MIP) post-processed.Spinal nerveroots were observed.Results The PROSET could show dura,dura sheath,spinal nerveroot,ganlias,segments of the nerves posterior to the ganglions well and could be observed from multiple aspects by the 3D MIP.Among the 47 cases of luber nerve root disease,PROSET could show the level of the invasion and compression to the ganglias.Conclusion According to the PROSET technique and conventional MRI picture,can provide the satisfied proof to the diagnosis of lumbosacral nerve root diseases.

The paper aims to explore the studying method for the pharmacokinetics of drugs in target organs, the pharmacokinetic process of tramadol hydrochloride in the extracellular fluid of frontal cortex (FrCx) of mice was investigated. Six male mice (Kunming strain) were anaesthetized (urethane, 1.8 g x kg(-1), ip) and secured on a stereotaxic frame. A microdialysis probe was implanted into the FrCx and perfused with artificial cerebrospinal fluid at a flow rate of 2 microL x min(-1). One hour later, mice were administrated (ip) with tramadol hydrochloride (50 mg x kg(-1)) and dialysates were collected continuously at 12-min intervals (24 microL each) for 6 h. The tramadol concentration in dialysates was determined by HPLC-Ultraviolet detection method, and the concentration-time curve and pharmacokinetic parameters of tramadol were calculated with DAS software. The results showed that the pharmacokinetic process of tramadol in the FrCx extracellular fluid of mice was fitted to a two-compartment open model, and the main pharmacokinetic parameters t1/2alpha, t1/2beta, t(max), C(max) and AUC(0-infinity) were (0.27 +/- 0.05) h, (2.72 +/- 0.24) h, (0.50 +/- 0.10) h, (2 110.37 +/- 291.22) microg x L(-1) and (4 474.51 +/- 441.79) microg x L(-1) x h, respectively. In conclusion, a studying method for pharmacokinetics of drugs in the target organ is established, which is simple and feasible. Tramadol hydrochloride shows a two-compartment model in the extracellular fluid of the mouse FrCx, and the distribution- and elimination half-life are 0.5 h and 2.7 h, respectively.

Objective To preliminarily evaluate the efficacy and safety of chemotherapy on hemophagocytic lymphohistiocytosis(HLH) with hepatic dysfunction in children.Methods The children diagnosed as non-malignancy-associated HLH from Mar.2004 to Apr.2008 were selected,and the therapeutic effect was evaluated according to the HLH-04 protocol at the 8th week of chemotherapy,and the level of serum alanine aminotransferase(ALT),serum albumin(Alb) and plasma fibrinogen(Fib) were detected at pretherapy,2 weeks and 8 weeks of post-treatment.Results Altogether 60 HLH children complicated with hepatic dysfunction before chemotherapy,47 children had increased ALT,58 children had decreased Alb,and 38 children had decreased Fib.Forty-two cases(70%) were virus-associated HLH,1 case(1.7%) was fungi-associated HLH,and 17 cases(28.3%) had unknown origin.Among the 60 children,55 cases showed improvement in the 4 weeks of inductive treatment,15 cases gave up therapy,45 cases completed the 8 weeks of inductive treatment according to the protocol(among these children,42 cases had no active disease,3 cases had active disease),and these 45 children had obviously improved ALT,Alb and Fib at 2 weeks and 8 weeks of post-treatment,compared with pretherapy,the differences had statistical significance(Pa

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.
