Objective To observe the change regularity of IL-1?, IL-6, IL-10 and explore the mechanism of Yingfen syndrome (YS) in epidemic febrile diseases. Methods One hundred and four cases were divided into acute leukemia (AL) group and non-acute leukemia (NAL) group according to different diseases. According to syndrome differentiation of TCM, AL group was classified to 10 cases for Weifen syndrome (WS), 12 cases for Qifen syndrome (QS), and 20 cases for YS. NAL group was classified to 20 cases for WS, 24 cases for QS and 18 cases for YS. Fifteen healthy persons were selected for comparison. The levels of IL-1?, IL-6 and IL-10 in YS, WS and QS of various diseases were observed. Results In YS period, IL-1? and IL-6 increased continuously, while IL-10 decreased markedly, compared with healthy people (P 0.05), while on difference in IL-6, IL-10 between different diseases (P

Objective To investigate the protective effects of Jiangtangyishen Decoction on early-stage diabetic nephropathy of MKR mice. Methods Twenty-four MKR mice were randomly divided into three groups after stratification by sex and fasting plasma glucose, i.e. the model group, traditional Chinese medicine (TCM) group with Jiangtangyishen Decoction 16.72 g/(kg?d), western medicine group with Gliquidone 4.33 mg/(kg?d) and Benazepril 1.44 mg/(kg?d). In the same period, the C57BL/6 wilding mice were the normal group. After treated for 30 days, the levels of blood glucose, the content of microalbuminuria and ?2-microglobulin in urine were observed by ELISA. Renal pathologic lesion of each group were observed by light microscopy and electron microscopy. Results After treated for 30 days, TCM group had significant effect of decreasing fasting blood glucose, discharge of microalbuminuria and ?2-microglobulin in urine of MKR mice (compared with that before treated, P

Objective To observe the effects of Ganlu Xiaodu Dan and its incomplete prescription on expressions of MiR-146a and TLR4 mRNA in RD cells infected by EV71. Methods With technique of cell culturing, Ganlu Xiaodu Dan therapy group, incomplete Qing prescription therapy group, incomplete Li prescription therapy group, normal cells control group, model control group and ribavirin control group were set, and tests for virus toxicity and medicine toxicity in cells were taken, then expressions of miRNA-146a and TLR4 mRNA in these RD cells 24 hours after intervention with medicine were detected. Results Compared with normal cells control group, miR-146a in mRNA model control group decreased and TLR4 mRNA increased. Compared with model control group, miR-146a mRNA in Ganlu Xiaodu Dan therapy group, incomplete Qing prescription therapy group and incomplete Li prescription therapy group all increased while TLR4 mRNA decreased, and differences between ribavirin control group and model control group were not significant. Compared with Ganlu Xiaodu Dan therapy group, both expressions of miR-146a and TLR4 mRNA in incomplete Qing prescription therapy group were lower; miR-146a increased and TLR4 mRNA decreased in incomplete Li prescription therapy group. Compared with incomplete Qing prescription therapy group, miR-146a mRNA in incomplete Li prescription therapy group increased, but expression of TLR4mRNA between them was not significant. Conclusion Ganlu Xiaodu Dan can regulate the immune reactions caused by infection of EV71 by increasing expression of miR-146a mRNA and reducing expression of TLR4 mRNA. There may be antagonism effect between incomplete Qing prescription and incomplete Li prescription.

Objective To explore anti-EV71 effects of Ganlu Xiaodudan in vitro. Methods Ribavirin was taken as control drug, with the help of cell culture to observe anti-EV71 inhibition rate of Ganlu Xiaodudan in inhibiting-virus-directly experiment, therapeutic-inhibiting-virus experiment, preventive-inhibiting-virus experiment and preventive-therapeutic-inhibiting-virus experiment. Results In inhibiting-virus-directly experiment, therapeutic-inhibiting-virus experiment and preventive-therapeutic-inhibiting-virus experiment, virus inhibition rate of Ganlu Xiaodudan was higher than ribavirin. In preventive-inhibiting-virus experiment, virus inhibition rates of Ganlu Xiaodudan and ribavirin both were almost zero. Conclusion Ganlu Xiaodudan has better antiviral effects on EV71 than ribavirin, and it can affect more than one link of multiplication of EV71.

OBJECTIVE: To explore the nature of pathology of sluggishness of lung-defensive qi and to offer objective experimental indexes for weifen syndrome (defensive phase syndrome). METHODS: According to the completely random design, the plasma levels of vasoactive intestinal peptide (VIP) and thromboxane B2 (TX2) of 19 patients with weifen syndrome and 13 patients with qifen syndrome (qi phase syndrome) were detected by radioimmunoassay. The plasma levels of VIP and TX2 at different stages of weifen syndrome and qifen syndrome were observed. RESULTS: The plasma levels of VIP in weifen syndrome and in the late stage of weifen syndrome increased greatly at different stages as compared to qifen syndrome and the blank group (P < 0.01), while the plasma level of TX2 of weifen syndrome was higher only at the late stage than the blank group and qifen syndrome (P < 0.01). As for the levels of VIP and TX2 in weifen syndrome with different internal organs infected, there was no significant difference (P > 0.05). CONCLUSION: VIP may be an index reflecting the pathology of weifen syndrome, and it is one of the material foundations of sluggishness of lung-defensive qi, but it has nothing to do with the infected internal organs. The level of TX2 increases only after the fever of patients with weifen syndrome subsided, so it can not be the basis for diagnosis of the early stage of weifen syndrome. It doesn't increase in qifen syndrome either, the mechanism remains to be further studied.
