Because of the aggressive threaten of heat stroke and a lack of understanding of the mechanism of action, mammal animal models for experimental heat stroke were well developed. During the past 5 decades, anesthetized mouse, rat, rabbit, dog, baboon and monkey were used as animal model for experimental heat stroke. However, anesthetized mammals models have some limitations, such as neuroprotective effect of anesthetic agents, possible disturbance on injury and recovery of stroke animals by anesthetic agents, difficulty of discussing animal behavior before and after heat stroke, it was also difficult for the models to evaluate cognitive function of animal under hot environment. Considering humanitarian, only awaked and unrestrained mouse heat stroke model was accepted so far. Therefore, we also developed an awaked and unrestrained rat heat stroke model, and found it was helpful to evaluate drug effectiveness for animal behavior and cognitive function under hot environment.

Objective To investigate the significance of anti-mutated citrullinated vimentin(MCV)an- tibody in rheumatoid arthritis(RA)and study the correlation among anti-CCP,other antoantibodies and clinical manifestations of RA.Methods Anti-MCV antibody was detected by enzyme-linked immunosorbent assay (ELISA)in 166 serum samples including 74 from RA(18 cases with early RA and 56 cases with late RA),50 from non-RA rheumatic diseases and 42 cases of healthy blood donors.At the same time,other antuoantibod- ies were detected by different techniques,and their clinical meaning was investigated with the corresponding clinical data.Results Anti-MCV was found in 78%(58/74)of RA.The sensitivity and specificity of Anti- MCV in RA were 78% and 95%.The positive and negative predictive value was 97% and 71%.The average cut off concentration of Anti-MCV was(552?380)U/ml in RA,(162?63)U/ml in non-RA and(63?46)U/ml in healthy control.Anti-MCV was strongly correlated to anti-CCP(r=0.502,P=0.000),then AKA(r=0.408)anti APF(r=0.369).No differences was found between Anti-MCV and other clinical/laboratory parameters(P＞0.05). Conclusion Anti-MCV antibody may be a valuable diagnostic parameter for RA.Anti-MCV is more strongly correlated to anti-CCP than APE and AKA.It may not relate to disease activity and/or severity.

In the study, to explore the anti-tumor effects and mechanisms of chlorpromazine (CPZ) and perphenazine (PPZ) combined with temozolomide (TMZ) on human glioma cell lines, we performed MTT assays to determine the growth inhibitory rate of CPZ, PPZ and TMZ in mono and combined treatments. The anti-tumor effects of CPZ and PPZ alone or in combination with TMZ were determined by colony formation, cell apoptosis, cell cycle arrest, reactive oxygen species (ROS) production and mitochondrial membrane potential (MMP) detection (JC-1). The expression level of p53 was detected by immunofluorescence assay. Furthermore, autophagy under different administrations was detected by flow cytometry and confocal imaging to explore the anti-tumor mechanism of CPZ and TMZ. Protein phosphatase 2A (PP2A), cancerous inhibitor of protein phosphatase 2A (CIP2A) and proto-oncogene protein (c-Myc) were detected by immunofluorescence assay, tumor stem cell markers (CD44, CD133) and aldehyde dehydrogenase (ALDH) were detected by flow cytometry to explore the anti-tumor mechanism of PPZ and TMZ. The results showed that after 72 h treatments of combinations, the values of half maximal inhibitory concentration (IC₅₀) of TMZ on U87 and U251 cells were reduced, and the ability of TMZ to induce apoptosis and cycle arrest was improved. In addition, the combination of CPZ and TMZ could induce an increased effect of autophagy via activating the relevant pathway of p53 gene in glioma cells. The combination of PPZ and TMZ increased the sensitivity of glioma cells to TMZ, and the underlying mechanism might be related to the inhibition of CIP2A/PP2A/c-Myc signaling pathway. In conclusion, CPZ and PPZ combined with TMZ, showed the significant synergistic effects in cancer treatment, which are the novel and potential therapeutic regimens providing a new treatment strategy for human glioma.

Exploring the influence of extract of Ginkgo biloba (EGB) on the proliferation, apoptosis of ACC-2 cell in lacrimal adenoid cystic carcinoma and analyzing the influence of EGB on the gene expression of Survivin and TIP30 based on the levels of the gene and protein. ACC-2 cell in human with ACC of lacrimal gland disposed by EGB of different concentration was in vitro cultured. MTT method was used for cell proliferation detection. Annexin V/PI double-staining flow cytometer was used to detect cell apoptosis and cell cycle. Survivin and TIP30 gene expression together with protein expression were analyzed by RT-PCR and Western blotting. And it is indicated that EGB has inhibitory effect on the proliferation of ACC-2 cell in vitro. Furthermore, the dose-effect relationship was significant. Compared with the control group, it had statistical difference (P <0.01). The inhibitory concentration 50% (ICso) is 88 mg . L-1. By flow cytometer examination, it was indicated that EGB can gradually increase ACC-2 cell in G0-G1 stage and decrease it in G2-M and S stage. With the increase of dose, the apoptosis rate of ACC-2 cell obviously increased (P <0.05 or P <0.01). Both of the expression results of RT-PCR and Western hybrid proteins have showed that the concentration of EGB increased, it could be seen a significant decrease in Survivin gene expression (P <0.01). Meanwhile, the TIP30 gene expression got a significant increase. Therefore, EGB can effectively inhibit ACC-2 cell Survivin gene expression in human with adenoid cysistic carcinoma of larcrimal gland as well as promoting TIP30 gene expression, inducing the ACC-2 cell apoptosis and inhibiting tumor cell proliferation, which provided a certain theoretical and experimental basis for the application of Chinese herbal medicinal ingredient in the treatment of tumors.
