Comparative proteomic profiling of hippocampi in mice treated with Jingui Shenqi Pills and Liuwei Dihuang Pills / 中国中药杂志

The effects of Jingui Shenqi Pills(Jingui) and Liuwei Dihuang Pills(Liuwei) which respectively tonify kidney Yang and kidney Yin on brain function have attracted great attention, while the differences of protein expression regulated by Jingui and Liuwei remain to be studied. This study explored the difference of protein expression profiles in the hippocampi of mice orally administrated with the two drugs for 7 days. The protein expression was quantified using LC-MS/MS. The results showed that among the 5 860 proteins tested, 151, 282 and 75 proteins responded to Jingui alone, Liuwei alone, and both drugs, respectively. The ratio of up-regulated proteins to down-regulated proteins was 1.627 in Jingui group while only 0.56 in Liuwei group. The proteins up-regulated by Jingui were mainly involved in membrane transport, synaptic vesicle cycle, serotonergic synapse, dopaminergic synapse and so on, suggesting that Jingui may play a role in promoting the transport of neurotransmitter in the nervous system. The proteins down-regulated by Liuwei were mainly involved in membrane transport, synapse, ion transport(potassium and sodium transport), neurotransmitter transport, innate and acquired immune responses, complement activation, inflammatory response, etc. In particular, Liuwei showed obvious down-regulation effect on the members of solute carrier(SLC) superfamily, which suggested that Liuwei had potential inhibitory effect on membrane excitation and transport. Finally, consistent results were obtained in the normal mouse and the mouse model with corticosterone-induced depressive-like behavior. This study provides an experimental basis for understanding the effect of Jingui and Liuwei on brain function from protein network.

Effects ofJingui Shenqi Pills on Expressions of Testicular TGF-β1 and CYP19 in Kidney-yang-deficiency Rats / 中国中医药信息杂志

Objective To observe the effects ofJingui Shenqi Pills on the expressions of TGF-β1, CYP19, sex hormone level and sperm quality;To discuss its mechanism for the treatment of male sterility.Methods Forty adult male SD rats were randomly divided into normal group, model group, retardant group andJingui Shenqi Pills group, 10 rats in each group. Except for the normal group, adenine was used to induce healthy rats to kidney yang deficiency and sterility model rats. Normal group was given normal saline for gavage;retardant group was injected with testicular mesenchyme TGF-β1;Jingui Shenqi Pills group was givenJingui Shenqi Decoction for gavage. Blood was taken through caudal vein. Immunohistochemical, radioimmunoassay and electron microscopy observation were used to detect the expressions of TGF-β1, CYP19, sex hormone level, sperm density and motility rate and testicular morphological changes.Results Compared with normal group, the expression of TGF-β1 in the model group increased and CYP19 decreased (P<0.05). Compared with model group, the expression of TGF-β1 decreased and the expression of CYP19 increased (P<0.05). Compared with normal group, the number of sperm quantity was small and paramorphia in model group (P<0.05). Compared with model group, T, E2, sperm density and motility rate increased significantly inJingui Shenqi Pills group and retardant group (P<0.05). There was no statistical significance among indexes in retardant group andJingui Shenqi Pills group.ConclusionJingui Shenqi Pills can improve sperm quality and sex hormone level of model rats with kidney-yang-deficiency, which mechanism is probably realized by inhibiting the expression of TGF-β1R and promoting the expression of CYP19 in testis to effect development and proliferation of sperm.
