Objective To explore the relationship between dopaminergic axon terminal and GABAergic neurons and explore the neuroanatomic mechanism of their effects in schizophrenia. Methods The co-location and the association of dopaminergic axon terminal and GABAergic neurons in the basolateral nucleus (BL) of rat amygdala were examined by using double labeling immunoelectron microscopic techniques. Dopaminergic axon terminal and GABAergic neurons were labeled with the antidopamine (anti-DA) and the anti-glutamic acid decarboxylase (anti-GAD) antibodies respectively. Results 43% of the DA-input synapses was observed to relate directly or indirectly to GAD-immunoreactive(IR) dendritic structures(DA/GAD), which includes single (38%), convergent (30%), serial (20%), and axoaxonic (12%) contact types.And 57% of the DA-input synapses was found to associate with unlabeled elements (DA/UE), which includes unlabeled perikarya (10%), dendrites (82%) and axons (8%). All of the synapses that show DA-IR terminals profiles were found to be symmetric (inhibitory) synapses.Conclusion These results suggest that the dopaminergic system in the BL of rat amygdala controls the mediations of the GABAergic interneurons via symmetric synapses. In addition, the dopaminergic axon terminal associates with the glutamatergic projection neurons and exerts influence on its activity.

Objective To study the transfection efficiency, protein expression, and effect of adenovirus-mediated transfection on microvascular endothelial cells transfected by angiopoietin-related protein 2(Ad. ARP2)gene. Methods Mice coronary microvascular endothelial cells(CMECs) were isolated, cultured and transferred by Ad-ARP2. The transfection efficiency and cellular toxicity of adenovirus vector to CMECs were detected by immunofluorescence staining. Expression of Ad. ARP2 in CMECs and the secreted materials in culture medium were measured by Western blot and ELISA and compared among groups of Ad. ARP2, Ad. null, and PBS control. Vascular endothelial cells were incubated with conditional medium containing secreted ARP2, and effects on cells sprouting were observed in matrigel. Results Adenovirus-transfected CMECs showed a very high efficiency. When multiplicity of infection (MOD was 200, the transfection efficiency was 93. 5% ,and no harmful effect on CMECs growth was found. When CMECs were transfected with Ad. ARP2, there was a high ARP2 expression, which was significantly different from that with Ad. Null or PBS. The conditional medium containing ARP2 had an excellent ability to stimulate sprout of CMECs which phenomenon could not be seen in the control groups. Conclusions Adenovirus vector can be transferred into CMECs efficiently and safely. Ad. ARP2 gene transfection allows a high transient expression, and the expression products can stimulate the sprout of microvascular endothelial cells in vitro very well.

Aim To investigate the effect of CD44 anti-body-A3 D8 on the expression of IL-3 Rα and down-stream PI3K/Akt in NB4 cells. Methods The ex-pression of IL-3 Rα mRNA was detected by real-time quantitative RT-PCR, the IL-3Rα protein expression and changes of PI3 K/Akt signal pathway in NB4 cells treated with A3D8 were analyzed by Western blot. An-nexin-V-FITC/PI double staining flow cytometry was u-tilized to detect the apoptotic cells. The inhibitor of PI3 K/Akt signaling LY294002 combined with A3 D8 was used to inhibit the PI3K/Akt in NB4 cells. Re-sults After treated with A3 D8 , both the transcription-al level and translational level of IL-3 Rα were remark-ably reduced, and the PI3K/Akt pathway was inhibi-ted. LY294002 improved the inhibitory and apoptotic effects of A3D8 on NB4 cells. Conclusion CD44 antibody A3 D8 can downregulate the expression of IL-3Rα and inhibit the downstream PI3K/Akt pathway.

Objective To explore the differences of patient comfort and nursing workload between ultrasound guidance on upper arm placement of PICC and traditional placement of PICC, and to provide a reference for correct selection of catheter way. Methods Using a nonrandomized controlled study, a total of 1 116 patients were divided into the control group and the observation group, patients with traditional placement of PICC were set as the control group, and the patients with upper arm placement of PICC were named as the observation group. The patient comfort and workload of use and maintenance of PICC by nurses were compared between two groups. Results The incidence of catheter sliding out of PICC in the observation group was 1.9%(7/365), obviously higher than that of the control group, which was 0.3%(2/751), the difference was significant (χ2=8.37,P=0.007). The patient comfort had no statistical significance between two groups (t=2.13,P=0.082). The workload of use and maintenance of PICC in the observation group were (1.87±0.31) min and (9.16±1.07) min ,which were obviously higher than that of the control group [(0.85±0.16) min and(7.22±2.13) min] in winter (t=4.39, P=0.022;t=3.44, P=0.041), but there was no statistical significance between two groups in summer (P>0.05). Conclusions The workload of use and maintenance of PICC on upper arm placement was higher than traditional placement of PICC in winter, but the obvious differences of patient comfort and nursing workload in summer between the two PICC groups were not been found.
