Chinese Traditional Patent Medicine 1992;0(01):-
Objective:To study the transdermal permeability of Psoralen (Pro) and Isopsoralen (Isopro). Methods:V C two compartment was adopted to research the permeability deferences between Pso and Isopso in nude mouse skin in vitro, and investigated the effect of penetration enhancers, such as EtOH, azone and glycerol on the permeability of them. Results: Pso and Isopso are suitable compounds for transdermal delivery system and the permeability coeffient of Isopso is larger than that of Pso. 10% EtOH-1% Azone greatly increased the permeability coefficient. Conclusion: The results can offer reference for Psoralea corylifolia TDS.

Objective To explore the effect of inflammation and autoimmunity in peripartum cardiomyopathy(PPCM). MethodsA total of82 PPCM patients and 100 normal delivery patients were randomly selected and conducted epidemiological survey.High-sensitivity Creaction protein(hs-CRP),troponin I,human antimyocardial antibody IgG(AMA-IgG),Coxsackie B virus IgG(CBV-IgG)and adenovirus antibody IgG(ADV-IgG)were detected with ELISA. ResultsCompared with control group,PPCM patients had older age,higher pressure,higher proportion of cesarean section and infection.The levels of serum hs-CRP,cTNI,and leucocyte were markedly higher in PPCM patients compared with control.The positive proportion of AMA-IgG and CBV-IgG was significantly increased(P<0.01)in PPCM patients compared with the control.Logistic regression showed that infection(OR=2.87,95%CI 1.15-5.24),increased hs-CRP(OR=1.86,95%CI 1.08-4.02)and positive AMA-IgG(OR=2.68,95%CI 1.19-4.85)were independent risk factors for PPCM. ConclusionsInflammation and autoimmunity play an important role in peripartum cardiomyopathy.

Objective To investigate the effects of sodium aescinate(SA)on oxidative stress and pulmonary function during acute exacerbation of chronic obstructive pulmonary disease(COPD).Methods One hundred and twenty patients with COPD were randomly divided into two groups:the control group(n =60) and the treatment group(n =60).All patients were treated with routine anti-infection,oxygen inhalation,relieving phlegm and anti-asthma The treatment group took SA in addition to the routine beteropathy.The changes of serum SOD,MDA,GSH-Px,T-AOC,pulmonary functions and 6 minute walk distance(6MWD) were detected before and after two-week treatment in patients of the two groups to compare with 60 healthy subjects.Results The total effective rate in the treatment group was 91.67%,while 76.67% in the control group.The difference was statistically significant(x2 =5.065,P <0.05).Serum MDA level in both groups were comparatively higher than the healthy controls(9.25±1.55) μmol/L vs.(9.74±1.50) μmol/L vs.(2.06±0.29) μmol/L,P <0.001),while the levels of SOD,GSH-Px and T-AOC were lower than the healthy controls[SOD:(91.14±9.54) kU/L vs.(90.61±8.01) kU/L vs.(116.63±6.57) kU/L; GSH-Px:(139.38±36.56) U vs.(137.57±34.19) U/L vs.(189.34±35.54) U/L; T-AOC:(6.48±1.15) kU/L vs.(6.39±1.13) kU/L vs.(13.34±1.23)kU/L;P < 0.001].After treatment,all indexes of the two groups were obviously ameliorated in comparison with before treatment(P < 0.001),but the level of MDA[(4.56±1.39) μmol/L]in the treatment group decreased more greatly than in the control groups(P < 0.001).The levels of SOD[(103.85±7.07) kU/L],GSH-Px[(169.65±34.51) U/L],T-AOC[(10.52±1.09) KU/L],forced expiratory volume in 1 second/forced vital capacity(FEV1/FVC)[(60.49±6.11)%],FEVI%[(76.62±6.35)%]and 6MWD [(394.83±10.11)m]increased considerably more than those in the control group(P < 0.001).Conclusion Oxidative stress might be involved in the course of acute exacerbation of COPD.Sodium aeseinate can improve the pulmonary functions by ameliorating the oxidative stress during acute exacerbation in patients with COPD.

BACKGROUND:Liver fibrosis is a kind of chronic and active disease that is caused by various causes and characterized by the excessive accumulation of extracelular matrix. At present, use of Chinese herbs for the treatment of hepatic fibrosis has obvious advantages. Salvia miltiorrhiza has been shown to be highly effective in the treatment of hepatic fibrosis. However, the underlying mechanism needs further investigation. OBJECTIVE:To investigate the effects of TanshinoneⅡA on the expression levels of transforming growth factor-β/Smads signaling pathway related factors transforming growth factor-β, bone morphogenetic protein 7, Smad6 and Smad7 in the liver tissue of rats with hepatic fibrosis. METHODS:SD rats were randomly divided into three groups (n = 10): normal control, model and TanshinoneⅡA-treated groups. Rats in the model and TanshinoneⅡA-treated groups were subtaneously injected with olive oil-diluted 10% CCl4 ( 5 mL/kg) twice a week, 8 weeks in total, to build rat models of hepatic fibrosis. Four weeks after hepatic fibgrosis induction, rats in the TanshinoneⅡA-treated group received subtaneous injection of TanshinoneⅡA til eight weeks. Rats in the normal control group were subcutaneously injected with olive oil. RESULTS AND CONCLUSION: Western blotting and reverse transcription-polymerase chain reaction (RT-PCR) detection showed that in the model group, the expression of transforming growth factor-β in the rat liver tissue was significantly increased (P < 0.01) and the expression of bone morphogenetic protein-7, Smad6 and Smad7 was significantly decreased (P < 0.01) compared with the normal control group. TanshinoneⅡA could obviously reverse the expression of those factors above-mentioned (P < 0.01). The results suggest that TanshinoneⅡA can be used for treatment of hepatic fibrosis by decreasing the expression of transforming growth factor-β and increasing the expression of bone morphogenetic protein-7, Smad6 and Smad7.
