Objective To investigate the effect of CCAT1 on migration,invasion and epithelial-mesenchymal transition (EMT) in endometrial carcinoma (EC) cell.Methods Using quantitative PCR assay,level of CCAT1 was detected in EC tissues to find its association with the initiation and malignancy degree of EC.Wound heal assay and transwell invasion assay were performed to study the effect of CCAT1 on migration and invasion ability of EC cell,while qPCR and western blot assay were utilized to detect the levels of related genes.Results In EC tissues,level of CCAT1 was significantly upregulated (P < 0.001) and was positively associated with the malignancy degree of EC.After CCAT1 knockout,shorter migration distance was found,fewer cell passed through the chambers,levels of metastasis-related genes (MMP2 and MMP9) and mesenchymal markers (Snail,Zeb1 and Twist1) were up-regulated,and epithelial markers (E-cadherin and ZO-1) were down-regulated.Conclusion CCAT1 was up-regulated in EC tissue and its expression level was positively associated with the malignancy degree of EC.CCAT1 knockdown inhibited the metastasis,invasion and epithelial-mesenchymal transition of EC cell.

We have evaluated the plague epidemic situation in the Three Rivers Source Region,Qinghai Province in recent 20 years to provide the basis for revising the plague prevention countermeasures.We have analyzed the time distribution and the plague epidemic situation between animals and human beings during twenty years in the Three Rivers Source Region,Qinghai Province by describing epidemiology.The animal plague in the natural source of Marmot plague was extremely serious in the Three Rivers Source Region during the past 20 years.It mainly distributes in Yushu State and Tanggula County,Germu City and the serious season ran through the whole period of marmot camp ground activities and the peak was between June and August.Human plague epidemic took place between May and October each year and reached its peak between July and September.The peak covered about 41.67% at most.It mainly endemic distributes in Nangqian and Xinghai Country.During the past 20 years,we have totally found 14 human plague epidemics in the Three Rivers Source Region,among which 48 cases took place and there were deaths of 17 cases.The fatality rate was 35.42%.The lung type was the majority among 48 cases,which startde with the glandular type.During the past 20 years the plague epidemic has been active and the animal plague epidemic broke out continuously in the Three Rivers Source Region,Qinghai Province.The variety of animals and insects infected the plague epidemic was increasing.The human plague epidemics is most serious with high fatality rate,but it is on the decline as a whole.

The complete genome sequence of transmissible Gastroenteritis virus (TGEV) strain TS, previously isolated from Gansu province, was cloned and compared with published sequence data from other TGEV strains.Phylogenetic tree analysis based on the amino acid and nucleotide sequences of the S gene showed that the TGEV strains were divided into 3 clusters. TGEV TS showed a close evolutionary relationship to the American Miller cluster but had a 5' non-translated region (NTR) sequence closely related to the American Purdue cluster.Continued culture in different cell types indicated that TGEV TS virulence could be attenuated alter fifty passages in Porcine kidney (PK-15) cells, and that the Porcine kidney cell line IB-RS-2 (IBRS) was not suitable for culture of the TGEV strain TS.

Objective:To investigate the contents of soil metal elements in the plague high incidence area and resting area in the plague natural foci of Qingnan region in Qinghai Province, and to compare and analyze the differences of the contents of soil metal elements between the two areas.Methods:A total of 69 soil samples were collected from 11 sites in the plague high incidence area (Yushu Prefecture) and resting area (Guoluo Prefecture) in Qingnan region, including 39 samples from high incidence area and 30 samples from resting area. The contents of 12 soil metal elements, such as iron (Fe), magnesium (Mg), calcium (Ca), barium (Ba), cobalt (Co), copper (Cu), manganese (Mn), lead (Pb), rubidium (Rb), titanium (Ti), vanadium (V) and zinc (Zn), were measured by X-ray fluorescence spectrometry and SPSS 20.0 software was used for Spearman correlation and other statistical analysis.Results:The contents of Fe and Ca in the soil of the plague natural foci of Qingnan region were relatively high. The contents of 12 soil metal elements in the high incidence area were significantly higher than those in the resting area ( P < 0.01 or < 0.05). There were statistical significant differences in the contents of Mg, Ca, Ba, Mn, Pb and Zn in the soil among the sample plots of the plague high incidence area ( P < 0.01 or < 0.05). There were statistical significant differences in the contents of Fe, Mg, Ca, Rb and Ti in the soil among the sample plots of the plague resting area ( P < 0.05 or < 0.01). Except for Mg and Ca, Fe was positively correlated with other metal elements in the high incidence area and resting area ( P < 0.01 or < 0.05), and Fe was strongly positively correlated with Rb, Ti and V ( r = 0.780 - 0.838). Mg was only positively correlated with Ca in the high incidence area and resting area ( P < 0.01). Ca was negatively correlated with Mn, Pb, Rb, Ti, V and Zn in the high incidence area, and with Rb and Zn in the resting area ( P < 0.01 or < 0.05). The rest of the metal elements were mostly positively correlated in the high incidence area and resting area. Conclusions:The contents of Fe and Ca are rich in the plague natural foci of Qingnan region in Qinghai Province. There are correlations among most soil metal elements in the high incidence area and resting area. The correlation between the contents of soil metal elements in the plague natural foci and the epidemic of plague is worth further exploring.

In this study, the mature peptide sequence of a pectin lyase gene A was amplified from Aspergillus niger strain EIM-6 by using RT-PCR reverse transcription technique. The cloned gene was then inserted into a Pichia pastoris expression vector pPIC9k to produce the recombinant expression plasmid pPIC9K-pelA. By using electric shocks, we successfully transformed the recombinant pPIC9K-pelA into Pichia pastoris GS115. The activity of the engineered strain reached to 2.3 U/mL after induction with the final concentration of 1.5% methanol. SDS-PAGE analysis revealed that the pPIC9K-pelA transformant had an additional protein band of approximately 38 kD, which was not present in the control. There were no significant differences between the recombinant and native pectin lyase with regard to their hydrolysis activities.

Based on the correlation between Qi and blood in traditional Chinese medicine, the collateral disease theory puts forward that the Qi-collateral go hand in hand with the vessel-collateral of the brain, and to be as close as lips to teeth in structure and function, which is an important basis for the function of brain governing mind. And this theory proposes that deficiency/stagnancy of collateral-Qi, stagnation of collaterals and loss of consciousness are the main pathogenesis of Alzheimer's disease(AD), which is different from the research strategy of modern medicine focusing on neurons. It is suggested that it is necessary to treat AD from two aspects, including neuronal protection(elimination of pathological products such as β-amyloid and phosphorylated tau protein) and cerebral microvascular protection(protection of cerebral microvascular structure and function, promotion of therapeutic angiogenesis and increase of cerebral blood flow. Tongxinluo capsules is a representative drug for dredging collaterals developed under the guidance of the therapeutic principle of collaterals need circulation, it can protect microvessels and play a neuroprotective role mediated by vascular protection. Clinical studies have confirmed that Tongxinluo capsules can effectively treat AD, vascular dementia and cognitive impairment related diseases, which can provide new ideas and effective treatment ways to prevent and treat AD from neurovascular protection in a comprehensive manner.
