ABSTRACT
Objective To explore the molecular mechanism of the formulae for calming the liver and suppressing YANG in migraine rat model with syndrome of hyperactivity of the liver-YANG.Methods A rat model of migraine with hyperactivity of liver-YANG was established through electrical trigeminal ganglion stimulation and syndrome of oral administration of Fuzi decoction. The total proteins of the lymphocyte in the rats were separated by immobilized pH gradient-based 2-dimensional gel electrophoresis(2-DE), and the 2-DE image was analyzed by PDQuest 7.0 software. Matrix-assisted laser desorption/ionzation-time of flight mass spectrometry (MALDI-TOF-MS) and the SWISS-PORT and MSDB database were used to identify differential proteins.Results The formulae for calming the liver and suppressing YANG could also improve headache. Well-resolution and reproducible 2-DE patterns of rat lymphocyte from normal, model, and therapy tissues were obtained. Eleven of the total 13 differential protein spots were successfully identified by MALDI-TOF-MS. These proteins were alcohol dehydrogenase 3(ADH3), glycogen phosphorylase, ATP synthase D chain, annexin-3, ubiquitin, neutrophil defensin 4 precursor, melanoma-associated antigen E2, heat shock protein-27, annexin-A1, peroxirdoxin-Ⅱ, MU class glutathione S-transferase (Fragment)(GSH). Conclusion Differences occur in the expression of lymphocyte proteins in migraine rats with syndrome of hyperactivity of liver-YANG after treatment with the formulae for calming the liver and suppressing YANG, and the 11 identified protein spots may be associated with its mechanism.
ABSTRACT
Objective To observe the effect of jiaweibugan decoction on the expression of p-JNK mitogen-activated protein kinase in sciatic nerve of experimental diabetic rats and explore the preventive and therapeutic effects of Jiaweibugan decoction on peripheral neuropa-thy in experimental diabetic rats. Methods The diabetic rat model was established by streptozotocin (STZ). The rats were killed on the 4th or 8th week from the beginning of treatment, and the expression of p-JNK mitogen-activated protein kinase in sciatic nerve was detected by immunohistochemistry. Serum SOD was determined by xanthine oxidasemethod. Results The immunohistochemistry results showed that the expression of p-iNK in the model group on the 4th or 8th week was higher than that in normal control group (P<0.05) , while p-JNK in jiaweibugan decoction group was markedly lower than that in model rats(P<0.05). The results showed that SOD in the model group on the 4th or 8th week was lower than that in the normal control group (P<0.05) , while SOD in jiaweibugan decoction group was markedly high-er than that in model rats(P<0.05). Conclusion Jiaweibugan decoction has a preventive and therapeutic effect on peripheral neuropathy in experimental diabetic rats.

ABSTRACT
OBJECTIVE: To explore the pathogenic mechanism of liver-yang hyperactivity type of hypertension and to observe the effects of Pinggan Qianyang Formula (PGQYF), a compound of traditional Chinese herbals for calming the liver and suppressing yang, so as to provide experimental evidence for new marker proteins of drug therapy. METHODS: A rat model of liver-yang hyperactivity was prepared with spontaneous hypertensive rats (SHRs) by administration of Aconiti Praeparatae Decoction. Adrenal proteins were separated by 2D gel electrophoresis (2-DE). The differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and database analysis. RESULTS: The rat model of liver-yang hyperactivity was successfully reproduced, and the PGQYF could decrease the grades of irritability, conjunctival congestion and systolic blood pressure of the rats (P<0.05, P<0.01). After analysis, twelve obviously differentially expressed proteins were found, eight of which were identified. The expression levels of isocitrate dehydrogenase and steroidogenic acute regulatory protein in the untreated group were up-regulated as compared with those in the normal control group, and down-regulated in the treatment group. The expression levels of ferritin light chain, elongation factor Tu, Rho GDP disassociation inhibitor 1, flavin reductase and basic transcription factor 3 in the untreated group were down-regulated as compared with those in the normal control group, and up-regulated in the treatment group. CONCLUSION: Differentially expressed adrenal proteins in SHRs with live-yang hyperactivity are successfully identified. This approach may lay a foundation for the further investigation of pathogenic mechanisms in hypertension with liver-yang hyperactivity and the mechanisms of PGQYF treatment.

ABSTRACT
Objective:To establish criteria of commonly-seen TCM syndromes of depression.Methods:Consultation of specialists,clinical epidemiological survey,scores of syndrome degree rating and statistical analysis of multiple factors were adopted to establish the criteria for main syndrome differentiation of 5 commonly-seen TCM syndromes of depression.Results:Of 1977 cases of depression,1731 cases were stagnation of the liver-Qi,stagnation of the liver-Qi and deficiency of the spleen,stagnation of the liver-Qi and phlegm,deficiency of both the heart and spleen,and Yin-deficiency of both the liver and kidney.And according to statistical analysis,the criteria for main syndrome differentiation of the 5 syndromes were established.Conclusion:Commonly-seen syndromes of depression have common cause of disease and pathogenesis.Stagnation of the liver-Qi is basic syndrome,and in clinical manifestation of various syndromes emotional depression is common main syndrome,but various syndromes still have other main syndrome.
