Objective To investigate the effect of physical training on plasma N-terminal pro-brain natri- uretic peptide(NT-proBNP)levels in patients with chronic heart failure(CHF).Methods Eighty NYHAⅡ-ⅢCHF patients were randomly divided into a training group(n=42)and a control group(n=38).A 6-minute walk- ing test was performed within 24 hours after the patients were admitted.The 6-minute walking distance and plasma NT-proBNP levels were determined before and after 8 weeks of programmed physical training.The patients of both groups were treated with routine drugs for heart failure.6-minute walk training was only performed in the training group twice a day for 8 weeks.Results Physical training could significantly reduce plasma NT-proBNP levels and improve performance on the 6-minute walking test.Conclusions Physical training could significantly reduce plas- ma NT-proBNP levels and improve the motor function of patients with CHF,and could be helpful in delaying the de- velopment of CHF.

Objective To study the mechanism of mast cell increase in cellular leiomyoma of uterus.Methods Tissue sections from 30 cases of cellular leiomyoma of uterus,15 cases of leiomyosarcoma and 30 cases of ordinary leiomyoma were studied using immunohistochemical double labeling techniques.The expression of mast cell tryptase ahd Ki-67 as well as mast cell tryptase and chemotactic factors RANTES,Eotaxin,monocyte chemoattractant protein-1(MCP-1),transforming growth factor-? (TGF-?)were double immunostained.Results Ki-67 in mast cells was rarely expressed in each group. Expressions of regulate upon activation normal T cell expressed and secreted(RANTES),Eotaxin and TGF-? in cellular leiomyoma were 78%,89%,91%,respectively.They were all higher than those in ordinary leiomyoma and leiomyosarcoma(P

Objective To investigate whether the malignant transformation of macrophages ( Mφ) in glioma mesenchyme was induced by the fusion of glioma cells ( SU3 ) and Mφ.Methods SU3 cells transfected with red fluorescent protein genes were co-cultured in vitro with Mφexpressing enhanced green fluorescent protein.The cell lineages with RFP+/GFP+dual-color fluorescence were established by using monoclonal selection method.A series of tests for analyzing cancer-related phenotypes, tumorigenicity and specific markers for murine macrophage were performed.Results (1) A few of dual-color fluorescent cells were observed in the co-culture.Three monoclonal cell lineages (C3, C4 and C12) were obtained success-fully.(2) Three types of cells including RFP+, EGFP+and RFP+/EGFP+cells were formed during the cul-ture of monoclonal C12 cell lineage.The percentage of EGFP+cells was increased along the extended culture time and increased passages.Then, EGFP+cells gradually became the predominant cell population.Nota-bly, the percentage of RFP+/EGFP+cells were decreased and maintained at a low level, but the RFP+cells almost disappeared.(3) EGFP+cells from monoclonal C12 cell lineage showed the malignant characteristics such as loss of contact inhibition, rapid proliferation andchromosome aneuploidy, as well as high tumorigenic rate in nude mice (5/5).They also expressed macrophage specific marker CD68 and showed a large number of telocentric chromosomes.Conclusion The results of this study suggested that the malignant transforma-tion of host macrophages as previously observed in solid tumor might be induced by cell fusion occurred be-tween human glioma cells and macrophages.Along with the previous evidences showing the isolation of the malignantly transformed macrophages ( ihCTC) from solid tumor tissue of tumor-bearing mice, the results confirmed an objective existence of malignant transformation of host macrophages in tumor microenvironment. The malignant transformation of host cells induced by fusion with tumor cells revealed not only a new under-standing for the progression of tumor and cancer heterogeneity, but also new targets for cancer therapy.

The result was that CMCase was the highest when the level of carbon source was 9. 77 % , 8. 69 % and 9. 97% , and liquid volume was 64. 7 mL, 54. 2 mL, 40. 8 mL for carbon sources of millet straw, wheat straw and paper sludge, respectively. The value of CMCase was 29. 26IU/mL, 29. 14 IU/mL, 29. 81 IU/mL, respectively, in the above cases. The value of R2 is 0. 9117 , 0. 9246, 0. 8655 , respectively. It could be concluded that the fermentation models were quite reliable. The method can be applied in optimization of fungi fermentation medium.

This study is to investigate the effect of recombinant human interferon alpha 2b against broad-spectrum respiratory viruses in vitro. At the cellular level, the effect of the recombinant human interferon alpha 2b on influenza A virus was detected using real-time fluorescence quantitative RT-PCR. The effects of the recombinant human interferon alpha 2b on influenza B virus, parainfluenza virus, respiratory syncytial virus (RSV) and coronavirus were detected using cytopathic effect (CPE) method. In this study, the therapeutic index of recombinant human interferon alpha 2b anti-HPIV was 1476.63, the therapeutic index of recombinant human interferon alpha 2b anti-RSV was 141.37, the therapeutic index of recombinant human interferon alpha 2b anti-coronavirus was more than 2820.76, and the antiviral effect of recombinant human interferon alpha 2b was better than ribavirin (RBV). Recombinant human interferon alpha 2b has a stronger inhibitory effect on different influenza A virus RNA than drug control. The therapeutic index of recombinant human interferon alpha 2b anti-influenza B virus was 2.74, with modest effect. Recombinant human interferon alpha 2b in vitro has broad spectrum antiviral activities, low toxicity and high therapeutic index. Recombinant human interferon alpha 2b is expected to become the efficient medicine in clinical against respiratory viruses, as well as provide better services for prevention and treatment of respiratory viruses' infections.

OBJECTIVETo investigate the effect of four natures of medicine on therapeutic effect of acupoint sticking therapy.
METHODSSixty-one cases of primary dysmenorrhea were randomly divided into a capsaicin group (n=20), a menthol group (n=20) and a control group (n=21). They were treated respectively with capsaicin and menthol, which are extracts of Lajiao (Fructus Capsici) and Bohe (Herba Menthae) with same pungent in flavor and different cold (cool) and heat in property, and application of Tongjing Jiu Tieji (plaster for dysmenorrhea) at Shenque (CV 8). Changes of clinical symptoms before and after treatment were observed.
RESULTSAfter treatment, the cumulative scores of symptoms and the scores of pain decreased significantly in the 3 groups (P < 0.01), with no significant differences among the 3 groups (P > 0.05).
CONCLUSIONIn acupoint sticking therapy, the four natures of medicine have no obvious effect on the therapeutic effect, so the four natures of medicine should not used as main standard of medicine selection.
