OBJECTIVE: To explore the effects of Liangxue Huayu therapy (LXHYT), a traditional Chinese herbal therapy for cooling blood and dissipating blood stasis, on rat model of experimental autoimmune thyroiditis (EAT) and its impact on tumor necrosis factor-alpha and interleukin-10 mRNA expressions in peripheral blood mononuclear cells. METHODS: Forty Wistar rats were randomly divided into five groups: normal control group, untreated EAT group, cyclosporine A (CyA)-treated group, Tripterygium glycosides-treated group and Liangxue Huayu Recipe (LXHYR)-treated group. The interventions were given by gavage to the rats in different groups once a day. All rats were sacrificed after 4-week treatment, and the level of serum thyroglobulin antibodies (TgAb) and the changes of histological grade of thyroid specimen were assessed by blind evaluation. Expressions of tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) mRNAs in peripheral blood mononuclear cells were assessed by real-time reverse transcription polymerase chain reaction method. RESULTS: There was a significant increase in the serum TgAb level and severe inflammatory infiltration in the untreated group. Expression of TNF-alpha mRNA in peripheral blood mononuclear cells was increased, while the expression of IL-10 mRNA was decreased in the untreated group (P<0.01). Compared with the untreated group, CyA, Tripterygium glycosides and LXHYF could decrease the serum TgAb level (P<0.05), but the three interventions showed no significant improvement in thyroid inflammation (P>0.05). TNF-alpha mRNA expression was decreased, while IL-10 mRNA expression was increased as compared with the untreated group (P<0.05). CONCLUSION: LXHYT can decrease the serum TgAb level and recover the balance of Th1/Th2. This may provide an experimental basis for further research of assessing the antipsoriatic effect of Chinese herbal drugs with a rat model of EAT as an alternative model of psoriasis in vivo.

Chinese medicinal formulae( CMF) were often used in the clinics of traditional Chinese medicine (TCM) which were critical for modernization of Chinese medicine to shed light on the interaction between CMF and biological organisms. In current studies, correlation between system and part, macroscopic actions and microcosmic mechanism, ADME process and pharmacologic actions were often neglected. Thus, we put forward integrative pharmacology, which could integrate the correlation between CMF and biological organisms from multi-levels and multi-dimensional views. Integrative pharmacology would reveal the molecular mechanism of CMF for ailments treatment and screen out effective material systematically, which would be the new paradigm of TCM research.

Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

Dyslipidemia is a well-established risk factor for atherosclerosis. Treating dyslipidemia in elderly patients requires specific knowledge and understanding of common dyslipidemias and the relative safety of various pharmacologic agents in the presence of possible multiple comorbidities. Lifestyle modification remains the first step in the treatment of dyslipidemia; however, it can be difficult to sustain and achieve acceptable compliance in the elderly and it is best used in combination with drug therapy. Statins are widely accepted as the first-line therapy. Several recent studies have demonstrated that statins are safe and effective in the elderly. However, it is important to note that there is very limited data regarding the effects of dyslipidemia treatment on morbidity and mortality in patients over 85 years of age. In summary, the clinicians must recognize that the presence of dyslipidemia in the elderly poses substantial risk of coronary events and stroke. The available evidence has demonstrated that in most elderly patients who are at increased risk for cardiovascular morbidity and mortality, treatment of dyslipidemia with appropriate therapy reduces the risk, and when used carefully with close monitoring for safety, the treatment is generally well tolerated. With increasing life expectancy, it is critical for physicians to recognize the importance of detection and treatment of dyslipidemia in the elderly.

Idiopathic thrombocytopenic purpura(ITP) as an autoimmune disease,is the most common clinical hemorrhagic disease.But,its pathogenesis is not completely clear yet.Low platelet count can easily repeate in chronic ITP patients,there are poor efficacy in refractory ITP patients,too.In recent years,a series of important progress on the pathogenesis of ITP had been made.In the humoral mechanism,there were significant progress on the emergence of autoantibodies;the theory on anomaly of the megakaryocyte quantity and quality caused by autoantibody were put forward.In the cellular mechanisms,the theory on reduction in the number of Tr cells,Co-stimulative signal and platelets directly dissolved by cytotoxicity T cells were put forward also.This review will be made to sum up the study progress on the pathogenesis of ITP.

Objective To explore the significance of the changes of serum B cell activating factor(BAFF) in children with idiopathic thrombocytopenic purpura(ITP).Methods The concentrations of BAFF were detected by ELISA in 42 children with ITP(test group) before and after treatment in the Children′s Hospital Affiliated to Chongqing Medical University from Apr.to Nov.2008,the blood platelet count(BPC) was detected also.And 40 children who were operated selectively were selected as control group.The variation of concentrations of BAFF were analyzed among children with ITP before,after treatment and control group.Moreover,the relationship between serum BAFF expression and BPC were analyzed by the Pearson test.Results The concentrations of serum BAFF were higher in children with ITP before treatment compared with that in control group [(0.943 3?0.583 5) ?g?L-1 vs(0.538 9?0.234 7) ?g?L-1,P0.05).There was negative correlation between serum BAFF expression and BPC(r=-0.305,P

The risk factor of dental fluorosis are mainly related to the cancen tration of fluoride in the drinking water,the supplements of fluoride,nutrition states and regime,the time of fluoride exposure.Other factor such as the period of mother's milk feeding,the altitude of resident,the environmental pollution,the education degree of parents,and the level of health service of the community are also contributed to the development of dental fluorosis.Besides,the knowledge of dentists,the health habits of individual,the condition of economic,and so on is somehow the risk factor of dental fluorosis.The chances of fluoride exposure will become more often as the prosperous of the society.Thus any health policy of the complement of fluoride should be adapted to local conditions.

Objective To analyze the impact of tripterygium glycosides (TG) on the expression of CXCR3 and CCR4 gene in peripheral blood mononuclear cells from experimental autoimmune thyroiditis (EAT) rats, and to explore the possible mechanism for regulation of Th1/Th2 balance by TG. Methods EAT was induced in 20 rats, which were randomly divided into two groups, i.e., control group and TG group, to receive intragastric physiological saline and TG suspension (5.5 mg/kg) daily, respectively. The rats were killed 4weeks later, and total RNA was extracted from the peripheral blood mononuclear cells of rats and used for cRNA synthesis. The gene expressions of CXCR3 and CCR4 were detected with a Th1-Th2-Th3 microarray gene chip and realtime RT-PCR. Results Compared with the control group, there was a significant decrease in the mRNA expression of CXCR3 (0.52 ± 0.10 vs. 1.05 ± 0.17, P < 0.01 ) and CXCR3/CCR4 ratio (0.39 ± 0.22 vs. 1.04 ± 0.12, P< 0.01) in the TG group, together with an increase in the mRNA expression of CCR4 (1.56 ±0.13 vs. 1.02 ± 0.09, P < 0.01 ). Conclusions TG could regulate the number of Th1 and Th2 cells as well as their cytokine expression ratio likely by reducing CXCR3 and enhancing CCR4 expression, so as to modulate the Th1/Th2 balance in EAT rats.
