As the elements of local neuronal circuits, parvalbumin (PV)-containing interneurons in the basolateral nucleus (BL) of the amygdala play an important role in the amygdaloid functions of emotion, learning and memory. In order to investigate how the PV-containing interneurons in the BL are controlled, the synapses established on PV- containing interneurons in the BL of the rat amygdala were examined under immunoelectron microscopy using the double labeling methods with anti-PV and anti-dopamine (DA) antibodies for a reference of dopaminergic axon terminals. The results show that the PV immunoreactive (IR) neurons formed the synapses mainly on the dendritic structures from shafts of the dendrites to median and small dendritic branches. 68% of the synapses on the PV-IR profiles were formed by unlabeled axon terminals, and 32 % of them were formed by DA- (21 % ) and PV- (11 % )IR axon terminals. Majority of the synapses on the PV-IR neurons formed by unlabeled axon terminals were symmetric type, and only a small a mount of them were asymmetric that were observed between the PV-IR spines and unlabeled axon terminals and in the serial synapses in which an unlabeled axon terminal symmetrically contacted to another unlabeled axon terminal that, in turn, synapsed asymmetrically to the PV-IR dendritic profiles. The synapses formed between the PV-IR profiles and DA- or PV-IR axon terminals were exclusively symmetric. The present results suggest that the PV-containing interneurons in the BL of the rat amygdala were controlled by an inhibitory network formed by the symmetric synapses around them, among which the DA system was included.

Objective:To investigate the expression of transmembrane 4 super family 1 (TM4SF1)in breast cancer tissue,and to elucidate its clinical significance and explore the related molecular biological mechanisms. Methods:A total of 190 cases of human breast cancer,110 cases of paracancerous tissue and 110 cases of normal breast tissue were collected.Immunohistochemistry was used to detect the expression levels of TM4SF1 mRNA in breast cancer tissue,paracancerous tissue,and normal breast tissue;Western blotting method was used to detect the expression levels of TM4SF1 in breast cancer tissue,paracancerous tissue,and normal breast tissue;RT-PCR method was used to detect the expression levels of TM4SF1 mRNA in breast cancer tissue,paracancerous tissue, and normal breast tissue.The positive expression rates of TM4SF1 in breast cancer tissue of the breast cancer patients with different clinicopathological features were detected.Results:The positive expression rate of TM4SF1 in the breast cancer tissue was significantly higher than those in paracancerous tissue and normal breast tissue (P <0.05);there was no significant difference in the positive expression rates of TM4SF1 between paracancerous tissue and normal breast tissue (P = 0.531);the expression of TM4SF1 was not correlated with age,but was closely correlated with tumor size,differentiation degree,lymph node metastasis and tumor stage (P <0.05);the positive expression rate of TM4SF1 in basal like breast cancer tissue was higher than those in the other three types of tissues (P <0.05).The results of Western blotting showed that the expression level of TM4SF1 in breast cancer tissue was higher than those in paracancerous tissue and normal breast tissue (P < 0.05 ), but there was no significant difference in the expression level of TM4SF1 between paracancerous tissue and normal breast tissue (P >0.05). The results of RT-PCR showed that the expression level of TM4SF1 mRNA in breast cancer tissue was higher than those in the paracancerous tissue and normal breast tissue (P <0.01);there was no significant difference in the expression level of TM4SF1 mRNA between paracancerous tissue and normal breast tissue (P > 0.05 ). Conclusion:The TM4SF1 is highly expressed in breast cancer tissue. TM4SF1 may affect the occurrence, development and distant metastasis of breast cancer through various mechanisms.TM4SF1 may be a potential target for the treatment of breast cancer.

ObjectiveTo investigate the intestinal absorption characteristics of multi-index components in Danggui Buxuetang with drug absorption simulating system (DASS) established by everted intestinal sac model. MethodThe intestinal absorption solution at different time points after administration of Danggui Buxuetang was collected and detected by high performance liquid chromatography (HPLC), acetonitrile (A)-0.2% glacial acetic acid solution (B) was used as the mobile phase for gradient elution (0-16 min, 15%-23%A; 16-20 min, 23%-28%A; 20-25 min, 28%-30%A; 25-30 min, 30%A; 30-35 min, 30%-65%A; 35-45 min, 65%-95%A), the detection wavelength was 302 nm. HPLC fingerprint of intestinal absorption solution was established and the common peak was calibrated, and the relative cumulative absorption rate of each index component was calculated. The relative cumulative absorption curves of components were fitted with various mathematical models by DDSolver 1.0 to explore the absorption law of different components. ResultThe absorption process of C2 (calycosin-7-glucoside) and C6 in Danggui Buxuetang was in line with zero-order equation, C9 was best fitted by Weibull equation, and the remaining 7 components were in line with Makoid-Banakar equation. C1 with C2, C3, C5, C7 and C10, C2 with C5 and C7, C3 with C4, C5, C7 and C10, C4 with C6 and C10, C5 with C7, C6 with C10, C7 with C10, C8 with C9 were absorbed simultaneously during the absorption process. With the prolongation of time, the overall cumulative absorption rate of Danggui Buxuetang increased. At 120 min, the overall cumulative absorption rate of Danggui Buxuetang exceeded 38%, and reached 49.14% at 180 min. ConclusionTen ingredients in Danggui Buxuetang are absorbed in the jejunum, but absorption law of various components is different, which shows that the intestinal absorption of compound preparations of traditional Chinese medicine (TCM) has multiple characteristics. Intestinal absorption study of TCM compound preparations with chemical composition as the index can reveal some of its absorption law, but it is not complete.
