Effects of Langchuangjing Granule (狼疮净冲剂) on Apoptotic of CD_4^+T and CD_(19)^+B in Spleen of BXSB Mice with Systemic Lupus Erythematosus

Objective: To study the effect on apoptosis of CD 4 +T、CD 19 +B in spleen of BXSB mice with systemic lupus erythematosus treated with Langchuangjing Granule (LCJG, and to probe into the mechanism of the tr eatment. Methods: The apoptosis was examined by the flow cytometric analysis and immunofluorescence double-staining method. Results: Apoptosis of male BXSB mice speeds up. LCJG can restrain the excessive apoptosis of CD 4 +T and CD 19 +B cells in spleen. Conclusion: LCJG treated systemic lupus erythematosus by restraining the excessive apoptosis of T, B lymphocytes, probably restraining the release of excessive amount of apoptotic DNA fragments, so decreasing abnormal proliferation of B cells and the produce of autoantibodies.

Methods: Adopting the randomized double-blinded method, the effect of adding NYG to 30 patients with Parkinsonism in the treated group,

Long-Term Clinical Effect of Tangyiping Granules(糖异平颗粒)on Patients with Impaired Glucose Tolerance

Objective： To evaluate the long-term clinical effect of Tangyiping Granules（糖异平颗粒, TYP） on patients with impaired glucose tolerance（IGT） to achieve normal glucose tolerance（NGT） and hence preventing them from conversion to diabetes mellitus（DM）. Methods： In total, 127 participants with IGT were randomly assigned to the control（63 cases, 3 lost to follow-up） and treatment groups（64 cases, 4 lost to follow-up） according to the random number table. The control group received lifestyle intervention alone, while the patients in the treatment group took orally 10 g of TYP twice daily in addition to lifestyle intervention for 12 weeks. The rates of patients achieving NGT or experiencing conversion to DM as main outcome measure were observed at 3, 12, and 24 months after TYP treatment. The secondary outcome measures included fasting plasma glucose（FPG）, 2-h postprandial plasma glucose（2h PG）, glycosylated hemoglobin（Hb A1c）, fasting insulin（FINS）, 2-h insulin（2hI NS）, homeostatic model assessment of insulin resistance（HOMA-IR）, blood lipid and patients＇ complains of Chinese medicine（CM） symptoms before and after treatment. Results： A higher proportion of the treatment group achieved NGT compared with the control group after 3-, 12- and 24-month follow-up（75.00% vs. 43.33%, 58.33% vs. 35.00%, 46.67% vs. 26.67%, respectively, P〈0.05）. The IGT to DM conversion rate of the treatment group was significantly lower than that of the control group at the end of 24-month follow-up（16.67% vs. 31.67%, P〈0.05）. Before treatment, FPG, 2h PG, Hb A1 c, FINS, 2h INS, HOMA-IR, triglyceride（TG）, total cholesterol, low- and high-density lipoprotein cholesterol levels had no statistical difference between the two groups（P〉0.05）. After treatment, the 2hP G, HbA 1c, HOMA-IR, and TG levels of the treatment group decreased significantly compared with those of the control group（P〈0.05）. CM symptoms such as exhaustion, irritability, chest tightness and breathless, spontaneous sweating, constipation, and dark thick and greasy tongue were significantly improved in the treatment group as compared with the control group（P〈0.05）. No severe adverse events occurred. Conclusion： TYP administered at the IGT stage with a disciplined lifestyle delayed IGT developing into type 2 DM.

Effect of Zhongfeng Naodeping Granule on Hippocampal Excitatory Amino Acid and Neuron of Stroke-Prone Spontaneously Hypertensive Rats with Hemorrhagic Apoplexy

Objective: To observe the effects ofZhongfeng Naodeping Granule (ZFNDPG) onhemorrhagic apoplexy. Methods: The strokeprone spontaneously hypertensive rats(SHRsp ) were used to study effects ofZFNDPG on hemorrhage apoplexy. Excitatoryamino acid (EAA) concentration in hippocampus sector, neuronal density and ultrastructural changes in hippocampal CAI sector weremeasured. Results: In pathological modelgroup glutamate (Gin) and aspartate (Asp)concentration elevated obviously. With theZFNDPG treating SHRsp of hemorrhagicapoplexy, Gin and Asp concentration in hippocampal sector could be markedly inhibited,compared with model group, P < 0.05-0. 01. Neuronal morphology was observed:neurone injury was mild and neuronal densityincreased in hippocampal CA1 sector of treatment group, compared with model group, P< 0. 01. Electron microscopy showed t edema,degeneration and necrosis caused by hemorrhagic apoplexy were improved after theZFNDPG treatment. Conclusions: Effects ofprotecting neurone for SHRsp on hemorrhagicapoplexy might be associated with thatZFNDPG inhibited concentration of EAA.

Prediction of suitable water content in granulation of sintering mixture based on Litster's model

Suitable water content plays a decisive role in the granulation of sintering mixtures.Herein,a method was proposed to predict the suitable water content for effective granulation on the basis of Litster's granulation model.The granulation effectiveness of a sintering mixture was predicted by the model,with the allowance error of±10%.The effects of the water absorption properties,particle size composition and content of adhesive particles on the suitable water content were studied.The results showed that the allowable error of prediction was within±0.5%compared to the experimentally determined suitable water content.With an increase in adhesive powder content of mixtures with higher water absorption,the suitable water content increased to achieve similar granulation effectiveness.Moreover,as the amount of concentrates increased,the suitable water content first increased and then remained steady.The influence of the water absorption characteristics of the adhesive particles on the suitable water content was less than that of their particle size composition in the mixture.
