Systemic lupus erythematosus is a diffuse connective tissue disease, which is mediated by autoimmune mechanisms.It results in multiple autoanti-bodies in the serum and injury organs and systems.Modern medicine uses glucocorticoid as the main medicine in treating systemic lupus erythematosus.Glu-cocorticoid is pure yang product, not only wil it injure yin and qi for using long time, but also disturb syndrome type of traditional Chinese Medicine of SLE for using it in large number.In the starting phase of using glucocorticoid, if the patients present manifestation of toxic heat flourishing, we should clear heat and remove toxicity.If the patients present manifestation of yin deficiency and internal heat, we should nourish yin and clear heat.If the patients pre-sent manifestation of stagnated heat stagnation, we should remove toxic heat and blood stasis.In reduction stage of using glucocorticoid, patients present manifestation of qi and yin deficiency.Then we should benefit qi and nourish yin. In maintenance stage of using glucocorticoid, patients present manifesta-tion of yang deficiency of spleen and kidney.So we should warm the kidney and invigorate the spleen.During the whole course of treating, we should also care for blood stasis and toxin.The clinicians should also remove toxic heat and blood stasis depend on the changing of syndrome. Using GCS in treating SLE should depend on the syndrome differentiation and choose the right Traditional Chinese Medicine in order to reach the clinical effect.

[Objective] To observe the effect of Jiedu Quyu Ziyin decoction on TLR4 signaling pathway in macrophages of MRL/lpr lupus mice. [Method] MRL/lpr lupus mice were divided into four groups:model group, prednisone group, Jiedu Quyu Ziyin decoction group(hereinafter referred to as:Chinese medicine group) and prednisone plus Chinese medicine group (hereinafter referred to as:combination of Chinese and western medicine group). The mice were gavaged with saline, prednisone, Jiedu Quyu Ziyin decoction and prednisone added Jiedu Quyu Ziyin decoction for 4 weeks. Macrophages of lung, peritoneal and spleen were collected and the expression of related genes was detected by RT-PCR. [Result] TLR4 mRNA in lung macrophages, and TLR4 protein in splenic macrophages increased significantly(P<0.05) after the treatment of prednisone. The increased TLR4 protein in splenic macrophages was significantly decreased by combining with Jiedu Quyu Ziyin decoction(P<0.05). Prednisone can significantly reduce the TLR4 downstream molecules such as MyD88, IFN-α, iNOS mRNA expression in lung and peritoneal macrophages(P<0.05). The decreased MyD88 mRNA in lung macrophages was increased significantly by combining with Jiedu Quyu Ziyin decoction(P<0.05). [Conclusion] TLR4 signaling pathway is changed in macrophages after glucocorticoid administration in MRL/lpr lupus mice. Jiedu Quyu Ziyin decoction can reduce the abnormal glucocorticoid-induced TLR4 protein expression.

Outbreaks of pseudorabies (PR) have occurred in southern China since late 2011, resulting in significant economic impacts on the swine industry. To identify the cause of PR outbreaks, especially among vaccinated pigs, 11 pseudorabies virus (PRV) field strains were isolated from Guangdong province during 2013–2014. Their major viral genes (gE, TK, gI, PK, gD, 11K, and 28K) were analyzed in this study. Insertions or deletions were observed in gD, gE, gI and PK genes compared with other PRV isolates from all over the world. Furthermore, sequence alignment showed that insertions in gD and gE were unique molecular characteristics of the new prevalent PRV strains in China. Phylogenetic analysis showed that our isolates were clustered in an independent branch together with other strains isolated from China in recent years, and that they showed a closer genetic relationship with earlier isolates from Asia. Our results suggest that these isolates are novel PRV variants with unique molecular signatures.

[Objective] To study the basis of treating constipation with Shaoyao Gancao Decoction.[Method] Ancient and modern herbal and experience of famous doctors literature of Shaoyao Gancao decoction,Shaoyao(Peony) and Gancao(licorice) are reviewed and summed up.[Results] Shaoyao(Peony) and Gancao(licorice) themself have a certain purgative effect.Shaoyao is good at regulating abdominal qi and blood,"removing blood stasis and lump accumulation",eliminating abdominal evil,and thus plays a laxative effect.Gancao is good at detoxification,eliminating the toxin of stool,and thus plays a antitoxic and laxative effect.For constipation Shaoyao Gancao decoction is composed of raw Shaoyao and raw Gancao at a ratio of 3:1 to 2:1,and the general amount of raw Shaoyao is about 30g.[Conclusion]Shaoyao Gancao decoction has a good laxative effect,alone or its modified is suitable for a variety of constipation syndrome types.
