Objective To detect the apoptosis and the intensity of proliferation in different types of renal pathology in children with lupus nephritis (LN), analyzed the relationship between apoptosis and proliferation in LN. Methods Twenty - seven children (aged 7-16 years old, 21 type IV and 6 type V ) with biopsy- proven LN and nine as controls were included in the study. Apoptosis was detected by in situ nick- end labeling techniques (TUNEL) in renal biopsy samples. Immunohistochemistry was employed to detect the proliferating cells identified by proliferating cell nuclear antigen (PCNA) and detect the expressions of proteins of apoptosis associated gene PDCD5 and Caspase - 3 in these patients. Results 1. Compared to type V LN, the patients with type IV LN had more apoptolic cells,more PCNA positive cells and higher ratios of PCNA/apoptosis (P/A) in glomeruli. 2. There were no difference in expression of PDCD5 in glomeruli in type IV LN compared with those in type V LN. Numbers of apoptotic cells were observed in glomeruli. The expression of Caspase- 3 in type IV LN increased in glomeruli compared with that in type V LN. Conclusions The up- regulation of mechanism of apoptosis in type IV LN was less than that of type V LN. Caspase- 3 participated in the apoptosis of glomeruli of LN, but PDCD5 did not play a role during apoptosis of glomeruli of LN or the effect of PDCD5 promoting apoptosis was depressed.

Objective To evaluate the therapeutic effects of autolngous bone marrow mesenchymal stem cells transplantation in the early phase of acute renal ischemia-reperfusion(I/R)injury in rabbits and their impact on tubular epithelial cell apoptosis.Method Bone marrow mesenchymal stem cells(MSCs)were isolated and cultured in vitro.Thirty rabbits were divided randomly into transplanted group,control group and sham-operated group,10 in each group.Rabbits of transplanted group were induced acute renal I/R injury by clamping bilateral renal arteries for 90 minutes,then transplanted MSCs labeled with BrdU immediately after the resumption of circulation in kidney.The rabbits of control group were induced acute renal I/R injury and then infused with saline instead.The sharn operated rabbits were transplanted autologous MSCs labeled with BrdU after sham operation.Fortyeight hours after transplantation,all rabbits were sacrificed.Renal functional and structural damage were evaluated.MSCs derived BrdU positive cells were determined by immunostalning.Tubular epithelial cell apoptosis was arialyzed by usign TUNEL.The SPSS version 11.3 Software was used for statistical analysis.ANOVA were used to ana lyze the data of renal function and tubular epithelial cell apoptesis.Data of renal structure darnage were analyzed by using the nonparametric Kruskal-Wallis test.Results Compared with control group,the renal functional and struc tural darnage were significantly ameliorated(24 h,BUN:F=7.483,Ser:F:15.091;48 h,BUN:F:17.741.Scr:F=61.865;P<0.05),tubular epithelial cell apoptods Wsa reduced significantly in transplanted group(F=135.495,P<0.01).MSCs derived BrdU positive cell were detected in the renal tissues of transplanted rabbits.Conelusiu Autologous bone marrow mesenchymal stern cells transplantation is curative for acute renal I/R injury in rabbits.Bone marrow MSCs might ameliorate renal I/R injury by reducing tubular epithelial cell apoptosis.

In surgery operations, wound should be cleaned with warm sterilized saline solution. In order to reach rapidly warming the washing solution from the room temperature during the surgery, we designed a thermostatic medical infusion pump. The present paper mainly presents researches on the two temperature control methods in the standby mode and in the flushing mode of the system. In the standby mode, the traditional proportional-integral-derivative (PID) control algorithm was adopted. In the flushing mode, dynamic characteristics of the system was changed in real time, which made the thermostatic control process more complex, and the fitted control function combined with the PID control algorithm was adopted in this mode. The temperature control parameters were adjusted in real time according to the initial temperature and the flow rate of the washing solution to obtain a constant temperature of the washing solution, no matter how the initial temperature and the flow rate are changed. The experiment results showed that this kind of control system performed well with a high accuracy.

The purpose of this study is to investigate the effects of multiple-trough sampling design and nonlinear mixed effect modeling (NONMEM) algorithm on the estimation of population and individual pharmacokinetic parameters. Oxcarbazepine and tacrolimus were used as one-compartment and two-compartment model drugs, respectively. Seven sampling designs were investigated using various number of trough concentrations per individual ranging from 1-4. Monte Carlo simulations were performed to produce state-steady trough concentrations. One-compartment model was used to fit simulated data from oxcarbazepine and tacrolimus. The accuracy and precision of the estimated parameters were evaluated using the median prediction error (PE), the median absolute PE and boxplot. The results indicated that trough concentrations could yield reliable estimates of apparent clearance (CL/F). For oxcarbazepine, as the number of trough concentrations per subject increased, the accuracy and precision of CL/F, between-subject variability (BSV) of CL/F and residual variability (RUV) tended to be improved. For tacrolimus, however, although no improvement were observed in the accuracy of CL/F and BSV of CL/F, the PE distribution ranges were significantly narrowed and the RUV estimates were less bias and imprecise. In terms of algorithm, Monte Carlo importance sampling (IMP) and IMP assisted by mode a posteriori estimation (IMPMAP) were consistently better than other methods. Additionally, the sampling design had no significant effects on the individual parameter estimates, which were only depended on the interaction between BSV and RUV in various algorithms. Decreased in BSV and RUV levels can improve the accuracy and precision of the estimation for both population and individual pharmacokinetic parameter estimates.

Amygdala (AM) plays crucial roles in emotional learning, memory and behavior. These functions of AM are carried out by three main subnuclei (lateral nucleus, basolateral nucleus and central nucleus) in AM and closely related with a transcription factor, cAMP- responsive element binding protein (CREB) in the neurons of the AM. CREB can be phosphorylated (pCREB) in many kinds of neuronal processes to regulate the synthesis of proteins for the formation of memory processes. In order to identify what neuronal types express pCREB and how the pCREB levels changed at different time intervals after an emotional stress stimulation, the present study is designed to investigate pCREB-, glutamate (Glu)- and parvalbumin (PV)- immunoreactive (IR) profiles in AM and the levels of pCREB in AM after a stress of forced swimming (FS). The results showed that the pCREB expressed in the Glu-IR neurons but not in the PV-IR neurons, and the expression level of the pCREB increased dramatically after the stress. The present results suggested that pCREB modulates the emotional processes through the Glu-IR neurons and that the pCREB greatly upregulated to response to the emotional stimuli.
