Kyrgyzstan is a mountainous country in the northeastern part of Central Asia which shares borders to the southeast with China. Due to their extreme environment and climate, there are a diverse range of species of plants. Many of the plants used in Kyrgyz folk medicine have not been studied using modern scientific techniques. This paper introduced the basic situation of medicinal herbs in Kyrgyzstan by comparing the differences traditional use between China and Kyrgyzstan, and looked for traditional medicinal plant research to provide basis for the development and cooperation of China and Kyrgyzstan.

Objective:To investigate establishing the multiple clinical processes model and pathological characteristics of EAE model,and to provide the experimental value for reseaching MS. Methods:The animal model was established in Wistar rat by immunization with complete Freund adjuvant and GPSCH, the pathological changes of EAE were studied with the aid of light microscopy. Results : We can divide the EAE into five types by pathological changes and clinical manifestation: acute EAE, relapsing-remitting EAE, persistent progress EAE,benigh form EAE and delitescence EAE. Every type mainly showed congestion and inflammatory cuff of small blood vessels,disintegration and disappear of myelin sheath and degeneration of neurons,especially in spinal cord. Conclusion:Multiple clinical processes on EAE model of Wistar rat were established for the first time.it is an ideal animal model in studying MS.

Objective:To investigate pathological changes and the expression of the matrix metalloproteinases in rat EAE.Methods:The pathological changes of EAE were studied in Wistar rat with the aid of light and electron microscope and the expression and distribution of MMP-2,MMP-9 in different tissues were detected with the method of immunohistochemistry.Results:Light microscopy showed inflammatory cuff around small blood vessels were evident, disintegration and disappear of myelin sheath were observed. Electron microscopy showed a lot of loose and fragmental spiremes of myelin sheath, the component of axons and nissl bodies in neurons were disappeared. MMP-2,-9 were expressed intensively in vascular endothelial cells, meninges and accumulative inflammatory cells.Conclusion:MMPs take the roles in every aspect of the pathological changes in EAE, it can destroy the blood brain-barrier, degrade the myeline sheath, damage the axons and generate immunogens.
5. Inhibition of invasion and metastasis of human tonguesquamous cell carcinoma Tca8113 cells by Src kinase inhibitor PP2
Journal of Xi'an Jiaotong University(Medical Sciences) 2019;40(2):290-293
Objective: To investigate the inhibitory effects of Src kinase inhibitor PP2 on migration and invasion of Tca8113 cells. Methods: Tca8113 cells were cultured for 24 h with 5 mol/L, 10 mol/L and 20 micron mol/L of Src kinase inhibitor PP2. The effects of PP2 on the invasion and migration of Tca8113 cells were measured with Transwell chamber and scratch method, respectively. Results: After the treatment with PP2 for 24 h, the expression of p-Src in 5, 10, 20 μmol/L of Src kinase inhibitor PP2 treatment groups was significantly lower than that of the non-drug treatment group (all P<0.05). The number of Tca8113 cells in the non-drug treatment group and the 5, 10, and 20 μmol/L of Src kinase inhibitor PP2 treatment groups was (232.76±28.65), (186.53±21.34), (129.18±17.96), and (37.82±12.41), respectively; the number of migratory cells was (259.38±25.27), (193.45±20.18), (143.24±18.04), and (32.94±14.39), respectively, the cell migration rate was (11.51±0.84)%, (8.06±0.51)%, (5.13±0.57)%, and (3.18±0.12)%, respectively; the overall difference was statistically significant (F=73.852, 85.687, 48.157, all P=0.000). It had a negative correlation with PP2 dose. Conclusion: Src kinase inhibitor PP2 can effectively inhibit the invasion and migration of Tca8113 cells in the concentration-dependent manner, and it may have certain clinical value in the treatment of human tongue squamous cell carcinoma.

ObjectiveTo study the rehabilitation effect of physical therapy on patients with above knee amputation. Methods50 patients with above knee amputation were evaluated with FIM scale before and after physical therapy. ResultsThere was a significant difference before and after physical therapy(P<0.05). Conclusions Physical therapy is effective on patients with above knee amputation.

Microvesicles (MVs) are the heterogeneous mixtures of vesicles. MVs released by leukemia cells constitute an important part of the leukemia microenvironment. MVs might act as important reservoirs of microRNAs (miRNAs). It is worth evaluating whether MVs possess some unique miRNA contents that are valuable in understanding the pathogenesis. In this study, we investigated the miRNA expression patterns of Nalm-6-derived MVs, Jurkat-derived MVs and normal cell-derived MVs using miRNA microarrays. The potential target genes regulated by differentially expressed miRNAs were also predicted and analyzed. Results demonstrated that 182 miRNAs and 166 miRNAs were differentially expressed in Nalm-6-MVs and Jurkat-MVs, respectively. Many oncogenes, tumor suppressors and signal pathway genes were targeted by these aberrantly expressed miRNAs, which might contribute to the development of B-ALL or T-ALL. Our findings expanded the potential diagnostic markers of ALL and provided useful information for ALL pathogenesis.

Objective To evaluate the effects of different concentrations of parecoxib sodium on the rat sperm motility,capacitation and acrosome reaction in vitro.Methods The sperm samples from Sprague-Dawley rat epididymis were collected by Klinefelter diffusion method and randomly divided into 4 groups (n =18 each) using a random number table:control group (group C),and parecoxib sodium 100,500,1 000 μmol/L groups (P1-3 groups).Parecoxib sodium with the final concentrations of 100,500 and 1 000 μmol/L was added to the culture medium.The samples were then incubated for 5 h in an airtight container filled with 5 % CO2 at 37 ℃.Then sperm motility was examined in vitro at 37 ℃ and analyzed by the computer-assisted sperm analysis,including the sperm motility ((a + b)%),average path velocity (VAP),straight line velocity (VSL),curvilinear velocity (VCL) and amplitude of lateral head displacement (ALH).The capacitation effect was assessed by using the chlortetracycline staining and phase-contract microscopy.The acrosome reaction was evaluated by coomassie brilliant blue staining.Results The VAP,VSL,VCL and capacitation ability of the sperm were gradually decreased in C and P1-3 groups (P < 0.05).Compared with group C,(a + b)% in P2,3 groups and ALH in P2 group were significantly decreased (P < 0.05).There was no significant difference in the acrosome reaction between groups (P > 0.05).Conclusion Parecoxib sodium has significant inhibitory effects on the rat sperm motility and capacitation in a dose-dependent manner,while has no effect on the acrosome reaction in vitro.
