OBJECTIVETo observe the effect of Tetramethyl pyrazine (TMP) on the cytokines and inflammatory mediators in the serum and the synovial fluid of collagen-induced arthritis (CIA)rats, and further to investigate its possible mechanisms for treating rheumatoid arthritis (RA).

METHODSType II CIA rat model was established. Rats in the TMP group were administered with TMP at 50 mg/kg and 100 mg/kg, once daily. Dexamethasone at 2.0 mg/kg was intramuscularly injected to those in the Dexamethasone treated group, once daily. Normal saline at 2 mL/kg was given to those in the normal control group and the model group, once daily. All medication was started from the 7th day, lasting to the 35th day. CIA rats' foot swelling degree was observed. Contents of serum IL-1, IL-6, IL-2, NO and PGE2in the synovial fluid were detected by radioimmunoassay and nitrate reduction method.

RESULTSCompared with the normal group, the foot swelling obviously increased, contents of NO and PGE2 in the synovial fluid were obviously elevated in the model group (P < 0.01). Compared with the model group, the foot swelling could be obviously inhibited by 100 mg/kg TMP and Dexamethasone; serum levels of IL-1 and IL-6 obviously decreased, serum IL-2 level obviously increased, contents of NO and PGE, decreased (P < 0.01). TMP 50 mg/kg could obviously inhibit the foot swelling of CIA rats (P < 0.01). There was no statistical difference in other indices (P > 0.05).

CONCLUSIONSTMP at 100 mg/kg showed obvious inhibition on CIA rats. Its inhibitory effect might be correlated to inhibiting activities of endogenous cytokines and the generation of inflammatory mediators in inflammation local regions, improving contents of anti-inflammation cytokines, and inducing the balance of the inflammatory cytokine network.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

Objective To explore the distribution of specific allergens for children in Sichuan Province and provide the evidences of clinical diagnosis and treatment.Methods Totally 451 cases in West China Second University Hospital,from April to August of 2016,were detected for 20 kinds of allergen-specific immunoglobulin E (IgE) by a new reverse enzyme-allergosorbent test,SPSS 18.0 statistical analysis was used to evaluate allergen-specific IgE levels in different groups of age,gender and diverse population distribution of disease.Results A total of 282 cases among 451 subjects were detected as IgE positive and the positive rate was 62.53%,among which 248 cases were positive for inhaled allergen-specific IgE,and the positive rate was 54.99%.There were 261 positive cases in food allergen-specific IgE,and the positive rate was 57.87%.For inhaled allergens,the highest positive rate was dermatophagoides pteronyssinus (n=111,24.61%),then dermatophagoides farina (n=110,24.39%),and house dust (n=108,23.95%);For food allergens,the highest positive rate was milk (n=159,35.25%),then egg (n=111,24.61%),and house dust (n=108,23.95%).Conclusions Both Inhaled allergens and food allergens were the important cause of allergic disease for children in Sichuan area.Serum allergen specific IgE determination was helpful to understand the patient′s allergy status,and diagnose the allergic disease.

AIM:To explore the effect of aldosterone on visfatin gene expression and secretion in 3T3-L1 preadipocytes or adipocytes.METHODS:Aldosterone at concentration of 10-8 or 10-6 mol/L with or without 10-6 mol/L spironolactone was added to cultured 3T3-L1 preadipocytes or adipocytes for 24 h or 48 h.The mRNA levels of visfatin and mineralocorticoid receptor were measured using real time PCR.The concentration of visfatin in the culture medium was determined by ELISA.RESULTS:In 3T3-L1 preadipocytes treated with aldosterone,the mRNA expression of visfatin reduced and the mRNA expression of mineralocorticoid receptor(MR) increased,but the concentration of visfatin in culture medium was not regulated significantly by aldosterone.In adipocytes with aldosterone treatment,the mRNA expression of visfatin and visfatin concentration in culture medium reduced,and mRNA expression of MR increased.The effect of aldosterone was blocked by spironolactone to some extent.CONCLUSION:Aldosterone inhibits the gene expression and protein secretion of visfatin in 3T3-L1 adipocytes.

Objective To explore the diagnostic and prognostic significances of platelet parameters changes in Kawasaki disease(KD).Methods The platelet total(PLT),mean platelet volume(MPV),platelet distribution width(PDW)and plateletcrit(PCT)were measured in 23 cases of KD on acute febrile phase and early recovery phase.It was compared with 33 cases suffered from other febrile diseases during the same period and in similar ages.Each KD child should accept the cardiology ultrasonic examination.Results The level of PLT,PCT increased in KD patients.It was more significant in early recover period than in acute febrile period(P0.05).PLT negatively correlated with MPV,PDW(r=0.358,0.268 Pa0.05).Conclusions The changes of platelet parameter play a very important role in diagnosis of KD.But it still can not be certain that whether the changes can help us estimate the variety of the patients condition and prognosis of KD children.It requires further study.

Objective To investigate relationship between adiponectin and cardiac damage induced by aldosterone in SD rats. Methods Male SD rats were treated with aldosterone infusion for 4 weeks, systolic blood pressure (SBP) was measured every week. At the end of experiment, the myocardial structure was observed, the levels of adiponectin in plasma and adiponectin mRNA expression of adipose tissue in epididymal fat pad were measured. 3T3-L1 adipocytes treated with 10-8 and 10-6 moL/L aldosterone for 24 and 48 h, adiponectin mRNA expressions and adiponectin concentrations in culture medium were measured. Results Aldosterone induced only a slight increase in the SBP of SD rats[(123±7)mm Hg, P<0.05]. However, aldosterone significantly induced cardiac ultrastructure changes, such as mitochondrial swelling and disordered internal structures. Furthermore, the level of plasma adiponectin decreased 22.8% after aldosterone treatment for 4 weeks ( P<0. 05 ). When 3T3-L1 adipocytes were treated with 10-8 and 10-6 mol/L aldosterone for 24 h, adiponectin concentrations in culture medium decreased 21.8% and 27. 2%, respectively (P < 0. 05); for 48 h, adiponctin mRNA expressions decreased 22.1% and 37.4%, respectively ( P<0. 05 ). The effect of aldosterone was reversed by spironolactone,which was partly independent of SBP. Conclusions Low level of adiponectin may be involved in cardiac damage induced by aldosterone in SD rats.

The effect of globular adiponectiin (gAd)on the function of NIT-1 cells under high glucose medium was investigated. The results showed that gad could completely block the increase of NADPH oxidase components p47phox expression and recover mRNA expression of pancreatic duodenal homeobox-I ,paired box gene 6,glucose transpoter 2,and glucokinase except neurogenic differentiation factor 1 (P<0.05 or P<0.01). Whereas,impaired insulin secretion and mRNA expression at high glucose concentration were not significantly improved by gAd.
