RESUMO
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.
RESUMO
To observe the efficacy of herbs for calming liver and suppressing liver-yang in treatment of migraine patients with hyperactivity of liver-yang syndrome and to investigate its effects on the lymphocyte protein expression. This approach may lay a foundation for the further investigation of pathogenic mechanisms in migraine with hyperactive liver-yang syndrome and the curative mechanisms of calming liver and suppressing liver-yang treatment.
RESUMO
BACKGROUND: Abnormal changes of bone mineral density (BMD) easily occur in patients with non-insulin-dependent diabetes mellitus (NIDDM),however the mechanisms are still unclear.OBJECTIVE: To investigate the pathophysiological features of changes of BMD and metabolism in patients with NIDDM from the angle of traditional Chinese medicine (TCM) syndrome types.DESIGN: A case controlled and comparative observation.SETTING: Department of Endocrinology of Guangzhou General Hospital of Guangzhou Military Area Command of Chinese PLA PARTICIPANTS: Totally 103 cases (55 males and 48 females) of patients with NIDDM admitted in Department of Endocrine of Guangzhou General Hospital of Guangzhou Military Area Command of PLA from April 2003 to April 2004 were enrolled. They were, according to TCM syndrome types, divided into 3 groups: yin deficiency with heat excess (32 cases),deficiency of both qi and yin (36 cases), and deficiency of both yin and yang (35 cases) groups. The healthy persons of 30 staff, 16 males and 14 females, in the hospital were concurrently recruited as control group. Informed consent was obtained from all the subjects.METHODS: ①A dual-energy X-ray absorption meter was used to determine the bone mineral densities of orthophoric 1-4 lumber vertebrae, total hipbone and head of femur in left hip in each group. ② Radioimmunoassay was taken to measure the content of serum osteocacin (OC). ③Colorimetry was used to measure the level of serum tartrate resistant acid phosphatase (TRACP). ④ q-test and x2-test were respectively used for comparison of measurement and enumeration data.MAIN OUTCOME MEASURES: ①The BMD of the 1-4 lumber vertebrae, total hipbone and head of femur in left hip in each group. ②The morbidities of osteoporosis of subjects in each group. ③ The levels of OC and TRACP in each group.RESULTS:All 103 NIDDM patients and 30 healthy subjects entered the final result analysis. ① The BMD of the 1-4 lumber vertebrae, total hipbone and head of femur in left hip of subjects: The BMD in yin deftciency with heat excess, deficiency of both qi and yin and control groups were obviously higher than that in deficiency of both yin and yang group (P ＜ 0.05-0.01 ) ② The morbidity of osteoporosis: The morbidities of osteoporosis in yin deficiency with heat excess, deficiency of both qi and yin and control groups were obviously lower than that in deficiency of both yin and yang group[34%(ll/32),42% (15/36), 33% (10/30), 71% (25/35),P ＜ 0.01]. ③ The level of OC: The levels in yin deficiency with heat excess and deficiency of both qi and yin groups were obviously higher than that in deficiency of both yin and yang group (P ＜ 0.01 ), but lower than that in deficiency of both yin and yang group (P ＜ 0.05). ④ The level of TRACP: There was no significant difference among groups(P ＞ 0.05).CONCLUSION: ① The volume and formation of bone in NIDDM patients of deficiency of both yin and yang syndrome type were obviously lower than those in healthy persons and NIDDM patients of yin deficiency with heat excess and deficiency of both qi and yin syndrome types, and the osteoporosis morbidity in them was obviously higher than those in healthy persons and the other two syndrome-type patients. ② The quantity and formation of bone in NIDDM patients of deficiency of both yin and yang syndrome type were near to those in healthy persons.
RESUMO
Objective To establish two-dimensional electrophoresis(2-DE) profiles with high resolution and reproducibility in analysis of hypothalamuses in the spontaneous hypertension rats(SHR) with hyperactivity of liver-yang to analyze the difference on the total proteins of hypothalamuses between the SHR and normal rats.Methods The total proteins of hypothalamuses in the rats were separated by immobilized pH gradient-based two-dimensional gel electrophoresis.With coomassie blue staining,the 2-DE image was analyzed by PDQuest 7.0 software.Results The average matching rate of the 2-DE images of hypothalamuses in the two kinds rats was 92% with good reproducibility.Proteins were mainly displayed at range of pI3-8,Mr(14.4～75) kD.The average spots in the SHR with hyperactivity of liver-yang and in the normal rats were 777?27 and 780?31 respectively.There were 22 spots of proteins up-regulated more than two times and 25 spots down-regulated more than two times in the SHR with hyperactivity of liver-yang than those of the normal rats.Conclusion There are 22 spots of proteins up-regulated and 25 spots of proteins down-regulated in the SHR with hyperactivity of liver-yang,which may be involved in the development of hyperactivity of liver-yang.
