Objective To explore the effect of postweaning enriched environment and citalopram treatment during juvenility on the behaviour of male rats exposed to early adverse stress. Methods The newborn pups were randomly divided into maternal separation group (MS) and non-maternal separation group (NMS). Offspring were weaned on PND22 and housed in same-rearing groups under either standard or enriched conditions or citalopram treatment until adulthood. All of them were examined by sucrose consumption test, forced swimming test (FST) and morris water maze test (MWZ). Results (1) MS had significantly less consumption of sucrose intake (ml/g)(0.013 ±0.006, n = 10), compared with the following five groups (MS + EE (0.023 ±0.012, n = 8); MS + Drug (0.027 ±0.012, n = 9); NMS (0.022 ± 0. 007, n=11);NMS + EE (0.023 ±0.007, n = 7); NMS + Drug (0.032 ±0.011),n=7)), NMS + Drug had significantly increased the radio of sucrose consumption on NMS group. (2)The immobility in FST were longer in MS-experienced groups (MS (140. 19 ± 37.01) s, n = 8); MS + EE (129.41 ±29.50)s, n = 6) ;NMS + Drug (128.83 ±26. 11)s, n = 6)) than three non-MS groups (NMS (96.28 ±35.63)s,n = 7); NMS + EE (94.17 ±24. 87)s, n = 6) ;NMS + Drug (93.00 ±34. 21)s, n = 6)). (3) MS had shorter time and shorter percentage of distance spent in target quadrant in MWZ,citalopram treatment markedly improved spatial memory on NMS group. Conclusion Maternal separation applied in newborn rats induces a broad spectrum of behavioral changes reminiscent of depressive symptoms in humans, which might be reversed to some extent by EE and antidepressant in young adults.

BACKGROUND: Diabetes can lead to many complications. Of them, retinopathy is a common type. To explore the effect of erythropoietin in diabetic retinopathy, it is necessary to establish an animal model of similar pathologic features and high reproducibility in clinical retinal neovascularization.
OBJECTIVE: To investigate the protective effect of vitreous cavity injection of erythropoietin on optic nerve of rats with diabetic retinopathy.
METHODS: Rat models of diabetic retinopathy were established and injected with erythropoietin through vitreous space for 14 consecutive days. Results were compared between the model and normal control groups.
RESULTS AND CONCLUSION: (1) Transmission electron microscope: compared with the model group, retinal ganglion cel nucleus presented uniform red; cel membrane was intact; endoplasmic reticulum exhibited slight swel ing. A smal number of vacuoles were found in mitochondria around the nuclei. (2) Western blot assay and RT-PCR: compared with the model group, Caspase-3 and Bax protein expression was lower in the erythropoietin group (P < 0.05). Caspase-3 protein and Bcl-2 protein expression was significantly higher in the erythropoietin group than in the model group (P < 0.05). Significant differences in nuclear factor κB and Survivn gene expression were detected between the model and erythropoietin groups (P < 0.05). (3) Results verified that vitreous cavity injection of erythropoietin had neuroprotective effect on rats with diabetic retinopathy, which may be associated with the inhibitory effect on apoptosis.

OBJECTIVE To investigate the effects of Isodon ternifolius extract on Toll -like receptor 4(TLR4)/nuclear factor - κB(NF-κB)/NOD-like receptor protein 3(NLRP3)pathway in hepatic stellate cells and hepatocytes . METHODS Using primary hepatic stellate cells and primary hepatocytes of rats as subjects ,inflammatory injury model was induced by lipopolysaccharide (LPS,100 ng/mL). Using colchicine (1 μmol/L)as positive control and TLR 4 inhibitor(TAK-242,1 μmol/L)as reference ,the contents of transforming growth factor -β1(TGF-β1),α-smooth muscle actin (α-SMA),type Ⅰ collagen(COL-Ⅰ),COL-Ⅲ in the supernatant of hepatic stellate cells ,and the contents of alanine aminotransferase (ALT),aspartate aminotransferase (AST),interleukin-1β (IL-1β) and IL -18 in the supernatant of hepatocytes were detected after intervention with I. ternifolius extract(1 mg/mL). The mRNA expressions of TLR 4,inhibitor α of NF -κB(IκBα),NF-κB p 65,NLRP3,Gasdermin D (GSDMD),apoptosis-associated speck -like protein containing CARD (ASC) and protein expressions of TLR 4, phosphorylated I κBα(p-IκBα),NF-κB p 65,NLRP3,GSDMD,ASC in the above cells were determined . RESULTS Compared with LPS model group ,the contents of TGF -β1,α-SMA, COL-Ⅰ and COL -Ⅲ in the supernatant of hepatic stellate cells and the contents of ALT ,AST,IL-1β and IL -18 in the supernatant of hepatocytes were significantly decreased ;the mRNA expressions of TLR 4,NF-κB p 65,NLRP3,GSDMD,ASC and the protein expressions of TLR 4,p-IκBα,NF-κB p 65,NLRP3,GSDMD,ASC in the two kinds of cells were significantly down - regulated,and the mRNA expression of I κBα was significantly up -regulated in all administration groups (P<0.05). Compared with TLR 4 inhibitor group ,the improvement of most of above indexes was more significant in the TLR 4 inhibitor+I. ternifolius extract group (P<0.05). CONCLUTIONS I. ternifolius extract could inhibit the activation of TLR 4/NF-κB/NLRP3 pathway, reduce the release of fibrosis factors and inflammatory factors ,alleviate the inflammatory injury of liver cells ,and inhibit the activation of hepatic stellate cells ,so as to protect liver cells and resist liver fibrosis .
