This study was aimed to explore the antidepressant effect of Kai-Xin Jie-Yu (KXJY) prescription on depressive model of rats,and to explore the level of inflammatory cytokines in peripheral blood.According to sucrose preference and weight,male SD rats were randomly divided into the normal group,model group and traditional Chinese medicine (TCM) group.The model of depression was established by chronic unpredictable mild stress and separation for @@6 weeks.Body weight,sucrose preference and forced swimming test were used to evaluate the depressive state.The levels of IL-1β,IL-2,IL-6 and TNF-α in the serum of rats were measured by ELISA.The results showed that compared with the normal group,the weight,sucrose preference and total drinking water of rat model gToup were significantly reduced.The immobility time of forced swimming was significantly prolonged.The level of IL-1β,IL-2,IL-6 and TNF-α expression in serum was significantly increased.There was no significant difference between the body weight of rats in the model group and TCM group.The total amount of drinking water and sucrose preference were significantly increased.The immobility time of forced swimming was reduced.Levels of IL-1 β,IL-2,IL-6 and TNF-α expression were decreased significantly.It was concluded that KXJY prescription can improve depression symptoms in depression model of rats.It may be related to regulate the expression level of serum inflammatory cytokines.

This study was aimed to detect the expression of miR-665 in the hippocampal of depression rat model treated with Kai-Xin Jie-Yu (KXJY) decoction and bioinformatic analysis of target genes of miR-665,in order to investigate the role of miR-665 in the pathogenesis of depression and the antidepressant mechanism of KXJY decoction.The rat model of chronic stress depression was established and then treated with KXJY decoction for 42 days.The total RNA from hippocampus tissues was extracted.And the relative expression of miR-665 in hippocampus of rats in each group was detected by RT-qPCR.TargetScan and microRNAorg databases were used to predict target genes for miR-665.DAVID database was used to classify GO function and to analyze KEGG signaling pathway of target genes.The results showed that compared with the normal group,the expression level of miR-665 in hippocampus of the model group was significantly higher with significant difference (P ＜ 0.01).Compared with the model group,the expression level of miR-665 in hippocampus of Chinese medicine group and western medicine group decreased significantly with significant difference (P ＜ 0.01).The biological functions of miR-665 target genes were mainly concentrated in the response to organic substance.The signal pathway was mainly concentrated in N-Glycan biosynthesis.It was concluded that miR-665 may be involved in the pathological process of depression,by correcting the abnormal expression of miR-665,which may be one of the antidepressant mechanisms of KXJY decoction.Through the analysis and prediction of the target genes,it provided a certain direction and theoretical basis for further study on the specific mechanism of KXJY decoction intervention on miR-665.

Objective To compare the bio-medical parameters in SIV infected Chinese rhesus monkeys with diverse disease progression,by which the pathogenesis of simian AIDS were to be investigated.Methods Sixteen Chinese rhesus monkeys were inoculated intravenously with SIVmac239 and followed-up for 18 months.Based on their progression patterns and plasma viral loads,animals were divided into 3 groups,including 1 rapid progressor( RP),13 normal progressors(NP),and 2 elite controllor(EC).Their parameters of haematology,virology,immunology and pathology were examined and compared. Results Compared with other animals,RM449(RP) showed higher viral load,unresponsive humoral immunity,and higher level of auto-antibodies against lymph node,thymus,and spleen.Additionally,its effector memory CD4 count was lower,with the transformation progress being blocked-like from naive/central memory subsets to effector memory subset,as the flow-cytometry assay showed.Notable decrease in its peripheral B cell was also observed,especially to the sub-population of tissue-like memory B cells and activated memory B cells.Pathological examination showed the depletion of lymphoid tissue,atrophy of spleen and loss of thymus.Moreover,most of these parameters of RM450 and RM453 (EC) changed opposite to that of RP.Conclusion The hallmarks of RM449 were higher viraemia and lower SIV specific IgG level,which may due to the disturbance of T cells and B cells development and differentiation.Moreover,destructions of organs of the immune system may contribute to the disturbance.Our study suggest that the change of micro-environments of thymus induced by SIV infection,which is necessary in T cell and B cell development and differentiation,may contribute at least partially to the AIDS pathogenesis.

In response to the issues of insufficient stability and accuracy in dry chemical detection using reflectance photometry,caused by the divergence and multiple internal reflections of the reflected light signal from the sample and the multilayer dry film test strip,a dry chemical reflectance photometry detection system based on an integrating sphere is designed.Firstly,an integrating sphere device is incorporated to reduce signal divergence and loss,ensuring even detection of the sample's reflected light signal and improving detection stability.Secondly,Light Tools optical simulation analysis is performed,and an integrating sphere detection model is established.Thirdly,the Williams-Clapper equation is employed to correct the error in reflectance density caused by multiple internal reflections,enhancing detection accuracy.Experimental validation demonstrates that the developed integrating sphere-based dry chemical reflectance photometry detection system improves the stability and accuracy of the detection system.
