BACKGROUND:Studies have shown that emodin protects against intestinal ischemia-reperfusion injury by inhibiting the release of inflammatory factors. OBJECTIVE:To investigate the effect of emodin on renal ischemia/reperfusion injury after bone marrow mesenchymal stem cel transplantation. METHODS:Forty Sprague-Dawley rats were randomized into five groups (n=8 per group):sham group, model group (renal ischemia/reperfusion injury group), bone marrow mesenchymal stem cel group (cel transplantation group), low-dose emodin group, high-dose emodin group. Rats in the latter four groups were pretreated with or without different concentrations (30 and 60 mg/kg) of emodin for 7 days, and then were subjected to clamping bilateral renal pedicles for 45 minutes, fol owed by injection of 1 mL bone marrow mesenchymal stem cel suspension. Six hours after reperfusion, the pathological changes of renal tissues were examined by hematoxylin-eosin staining;the mRNA levels of tumor necrosis factorα, interleukin-6, interleukin-18, TLR2 and TLR4 detected by real-time fluorescence quantitative PCR;and the protein expression of COX-2, ICAM-1 and iNOS determined by western blot. RESULTS AND CONCLUSION:Compared with the sham group, rats in the model group showed obvious features of severe acute tubular damage and inflammatory cel infiltration. In the cel transplantation group, tubular epitheliael cel s were partial y lost with some inflammatory cel s infiltrated in the renal interstitium. In the emodin groups, the tubular lumen was practical y intact with little renal interstitial inflammatory cel s. Compared with the sham group, a significant increase in the mRNA levels of tumor necrosis factorα, interleukin-6, interleukin-18, TLR2 and TLR4 as wel as in the protein levels of COX-2, ICAM-1 and iNOS was found in the model group (both P<0.05). However, bone marrow mesenchymal stem cel transplantation attenuated this ischemia/reperfusion-induced increase in the expression of the above-mentioned factors (P<0.05). Furthermore, the effects of bone marrow mesenchymal stem cel transplantation were further augmented by pretreatment with emodin in a dose-dependent manner. These findings suggest that emodin can enhance the protective effects of bone marrow mesenchymal stem cel s on renal ischemia/reperfusion injury.

Objective To observe the clinical effects of treating chronic type B hepatitis with Gankang Granule combined with poly I-C and immune ribonucleic acid. Methods A total of 100 cases of chronic type B hepatitis were randomly recruited into a control group and a treatment group, 50 cases in each group. The control group was treated with poly I-C and immune ribonucleic acid, while the treatment group was treated with Gankang Granule on the basis of the control group. Results Symptoms in both groups were improved. 23 eases in the treatment group showed negative value of HBeAg,contrasting to 13 cases in the control group. 38 cases in the treatment group turned to be negative value of HBV- DNA, higher than the number of 23 cases in the control group. The treatment group demonstrated a significantly better therapeutic results than the control group (χ2 value was 6.267 and 6.345 respectively, both P＜0.05). Conclusion Gankang Granule combined with poly I-C and immune ribonucleic acid can obviously improve hepatic functions and symptoms of chronic type B hepatitis,shorten the course of disease, and increase the rate of negative value of HBeAg and HBV- DNA.

Objective To study the effect of treating fatty liever with Tiaozhisugan decoction combined with simvastatin. Methods A total of 60 cases with fatty liver were randomly recruited into a control group and a treatment group.The control group was treated with simvastatin, vitamin E, and pioglitazone, while the treatment group was additionally treated with Tiaozhisugan decoction on that basis. Results The total effective rate was 93.9% and 79.6% in the treatment group and the control group respectively, the difference showing statistical difference (χ2=2.586, P＜0.01 ) .Conclusion It was effective to treat fatty liver with Tiaozhisugan decoction combined with simvastatin.

Objective　To study on dynamic laws of the human plague in China and America.Methods　The autoregressive models of human plague dynamics were set up.Results　Human plague were 7 923 and 398 cases in China and America between 1950 and 1998,respectively.The dynamic models ARIMA(1,2,0) of human plague in China and AR(1) in America between 1950 and 1998 were obtained,resectively.Conclusions　These general trends on the cases of human plague occurred have increased in China and relative stabilized in America between 1999 and 2001.

OBJECTIVE: To investigate the influence of budesonide on animal model of minimal persistent inflammation (MPI) of allergic rhinitis in rats and to investigate the changes of interleukin-12 (IL-12) in nasal mucosa. METHOD: Sixty Sprague-Dawley (SD) rats were randomly divided into four groups: group A (allergic rhinitis group), B (experimental group), C (MPI model group) and D (bland group) respectively, with fifteen animals in each group. Rats from group A,B and C were sensitized intraperitoneally by injection of suspension of ovalbumin (OVA) and aluminum hydroxide in 0.9% physiological saline. Then, repeated local booster sensitization with different concentration of OVA suspension (1% and 0.01%) or physiological saline into the nasal cavity of those rats were performed. For group D, physiological saline was used only. From 36th day, group B were given budesonide treatment for three weeks. A, C and D group were given normal saline nasal spray. Symptoms (sneezing) of rats after antigen challenge were observed and the infiltration of eosinophils (EOS) together with the expression of intercellular adhesion molecule 1 (ICAM-1) and IL-12 in the nasal epithelial cells were also examined. RESULT: When challenged with 1% OVA, the sneezing number of rats in group B was increased markedly than that in group D (P < 0.05). However, there was no difference between group B, A and C (P > 0.05). When challenged with 0.01% OVA and given budesonide, the symptom of sneezing almost disappeared in group B just like that in group D and there was no difference between the two groups (P > 0.05). Besides, there was still more EOS infiltrated in the nasal mucosa of rats in group C than that in group D (P < 0.05). There was no expression of ICAM-1 in nasal epithelium of rats in group D, nevertheless, ICAM-1 was found mildly expressed in group C. IL-12 expression was significantly increased compared with group A and group C, and was no significantly difference compared with bland group (P > 0.05). CONCLUSION Budesonide significantly inhibited the late reaction of animal model of minimal persistent inflammation (MPI) of allergic rhinitis in rats and increase the expression of IL-12 in MPI model.

This experiment showed that Yiqipingchuan Pills possessed obvious treatment action of cough and asthma,and expectorant action.It could cause a striking increase in the immunity-organ weight and carbon-particle clearance of hypoimmune mice.It was also found that these pills could make the con- centration of serum-hydrocortisone rise and the Vitamin C content in suprarene lower remarkably.

Objective To observe the therapeutic effect of thalidomide(Thd)on rheumatoid arthritis and its relation with the expression of hypoxia-inducible factor-1?(HIF-1?).Methods Female SD rats were randomly divided into two groups:a normal group and a model group.Each group was further divided into three subgroups:the control group,the vehicle group and the Thd group.The model group was subjected to collagen-induced arthritis.The Thd group and the vehicle group were given Thd(600 mg/kg)once daily and its vehicle DMSO respectively.The profile of arthritis was assessed by observing the clinical symptoms and histopathology and a qualitative clinical score of arthritis.The expression of HIF-1?in synovial tissuses was further detected by Western blot and immunohistochemistry technics.Results Compared to the control group with arthritis,clinical signs and pathological changes of arthritis were improved one and two weeks after ad- ministration of Thd respectively,and the qualitative clinical score of arthritis was evidently lowered.The ex- pression of HIF-1?in the inflammed synovial tissuses was found to be enhanced(P
