Objective To investigate the possible mechanisms of ox-LDL on vascular smooth muscle cells (VSMC) with and without exogenous zinc finger protein A20 gene. Methods VSMC were trans-fected with plamid containing A20 gene and incubated with ox-LDL. TLR4 and LOX-1 mRNA expression were measured by RT-PCR. Results After VSMC incubated with ox-LDL, the expression of LOX-1 and TLR-4 mRNA reached a higher level. However, when VSMC were transfected with plasmid containing A20 gene, the NF-kB nuclear translocation and the ability of migration reduced to normal level. Conclusions ox-LDL can significantly activate NF-kB signaling system and enhance migration in VSMC. The activation may induce the inflammatory response in arterial wall, the migration of VSMC to the intima, and triggering the process of atherosclerosis. Transfecting plasmid containing A20 gene significantly inhibited the activation of NF-kB and the ability of migration of VSMC. A20 effects might be through inhibiting NF-kB signaling. Meanwhile, A20 blocked the development of atherosclerosis.

Objective To know the distribution of arsenic and trace elements in drinking water in the endemic arsenism areas in Shanyin County, Shanxi Province. Methods Drinking water samples were collected from the chronic endemic arsenic poisoning areas of Silizhuang and Shanghexi, Shanyin County, Shanxi Province and HPLC-HG-AFS system was used to analyze the arsenic contents, valence and speciation. The trace elements were determined by ICP-MS. The data were analyzed by SPSS13.0 for windows. Results A total of 63 drinking water samples were determined, 39.68% of them exceeded the standard limit of arsenic level, inorganic arsenic was the main arsenical in drinking water, iAs3+/(iAs3++iAs5+) ratio was 56.17% in the water sample (arsenic was higher than 50 ?g/L) . The contents of Fe, Mn, Hg, Se and Pb in part of drinking water samples exceed the standard limits. No significant difference was seen between the arsenic results determined by HPLC-HG-AFS and ICP-MS. Conclusion Arsenic contamination of drinking water in Shanyin County, Shanxi Province is severe. The most frequently seen arsenic valence state in drinking water is iAs3+. Some trace elements in part of drinking water samples exceed the standard limits, this may aggravate arsenic poisoning.

Methods Relevant literature about breeding, planting, harvest, processing and storage of Lycium L. in CNKI from January 2004 to December 2013 was retrieved by computers. CiteSpaceⅡ was introduced to carry out key word analysis, high-frequency key word obtaining, co-occurrence network of high-frequency key words, and dendrogram of high-frequency words. Results Totally 759 articles were included. Key words about breeding were “genetic diversity”, “male sterile”, “its sequence”, “callus issue”, and“anther culture”. Key words about planting were“output”,“quality”,“hard twig cuttage”,“irrigation amount”. Key words about harvesting and processing were“picking machine of Lycium L.”,“drying kiln of Lycium L.”,“hot air drying”, and “combined drying”. Key words about storage were “pesticide residue”, “heavy metal”, and“organophosphorus pesticide”. Co-occurrence network of high-frequency key words showed that the research hotspots were pesticide residue, test of heavy metal and the storage of fresh fruits. Dendrogram of high-frequency key words showed that the high-frequency key words were “package”, “refreshment”, and “lycium barbarum polysaccharide”. Conclusion The research hotspots of planting of Lycium L. are planting skills effecting the output and quality of Lycium L.; In the field of harvesting and processing of Lycium L., design and research of picking machine has replaced traditional manual picking. Modern hot air drying has already replaced traditional drying in the sun or drying skills; In the aspect of storage of Lycium L., the study on the refreshment of Lycium L. has attached attention.

OBJECTIVE To investigate the effect of bevacizumab ,an anti-human vascular endothelial growth factor monoclonal antibody,on pulmonary dissemination of colorectal cancer. METHODS A metastatic colorectal cancer mouse model was established. Mice were randomly divided into two groups(n=8). The mice in experimental group were administered ip with bevacizumab at the dosage of 5 mg · kg-1,and those in control group were given isotype IgG at the same dosage. The antibodies were administered on 2 d before initiation of model establishment and 2 d after that,then once every 5 d for 4 weeks,for a total of 7 times. Liver and lung metastases were determined by histopathological examination. The chemokine receptor C-X-C receptor 4(CXCR4)and its ligand C-X-C ligand 12(CXCL12)mRNA expression in the lung were detected by quantitative RT-PCR. Human colon cancer cells HCT116 were treated with bevacizumab(5 mg·L-1)for 24 h. The expression levels of vascular endothelial growth factor receptor 1(VEGFR1)and CXCR4/7 protein as well as CXCR3/4/7 mRNA were examined by Western blotting and quantitative RT-PCR respectively. RESULTS The number of mice(2/8) with liver metastases was reduced,while the number of mice(8/8) with lung metastases increased in experimental group compared with isotype IgG-treated group(6/8 and 2/8 respectively,P<0.05). The mRNA expression level of CXCR4 and CXCL12 in lung tissue was significantly up-regulated in bevacizumab-treated group com?pared with control group(P<0.05). The mRNA and protein expression level of CXCR4 and CXCR7 was dramatically increased in HCT116 cells treated with bevacizumab(P<0.05). CONCLUSION Bevacizumab can potentially promote lung metastases of colorectal cancer,which may be related to up-regulation of CXCR4 and CXCL12 expression.

Objective To investigate the effect of different pressures of hyperbaric oxygen (HBO) treatment on neuropathic pain (NP) in rats.Methods Twenty-four healthy male Sprague-Dawley rats were randomly divided into 4 groups (n =6 each):sham operation group (group S),NP group,treatment with HBO at 2.0 atmosphere absolute group (group HBO2.0) and treatment with HBO at 2.5 atmosphere absolute group (group HBO2.5).The animals were anesthetized with intraperitoneal 5 ％ chloral hydrate 300 mg/kg.NP was induced by chronic constrictive injury.The left sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1-mm intervals with 4-0 silk thread.After the rats were placed in the HBO chamber,the pressure was increased at a rate of 10 kPa/min until the desired pressure was reached,and then the pressure was maintained at this level for 60 min.The pressure was then decreased at a rate of 10 kPa/min until the normal pressure was reached.HBO treatment was performed once a day for 5 consecutive days starting from 1st day after operation in groups HBO2.0 and HBO2.5.While the rats were only placed in the HBO chamber and stayed for 100 min in groups S and NP.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 0,1and 2 h after leaving the HBO chamber (T0.2).Results Compared with group S,MWT was significantly decreased and TWL was shortened in group NP (P ＜ 0.05).Compared with group NP,MWT was significantly increased and TWL prolonged at T1 during the treatment (P ＜ 0.05),while no significant change was found in MWT and TWL at T2 during the treatment in groups HBO2.0 and HBO2.5 (P ＞ 0.05).There was no significant difference in MWT and TWL at each time point during the treatment between groups HBO2.0 and HBO2.5 (P ＞ 0.05).Conclusion Treatment with different pressures of HBO can reduce NP in rats,but the change in pressure dose not affect the analgesic efficacy.

Objective To evaluate the effect of transforming growth factor-β (TGF-β) on the expressions of epithelial-to-mesenchymal transition (EMT)-related molecules in human A431 epidermal squamous cell carcinoma cells.Methods Cultured A431 cells were classified into two groups:TGF-β group treated with TGF-β of 7.5 μg/L for 72 hours,and control group remaining untreated.Subsequently,cell morphology was observed under an inverted microscope,and real time-PCR and Western blot were performed to quantify the mRNA and protein expressions of EMT-related molecules including E-cadherin,N-cadherin,vimentin and β-catenin respectively.Results After TGF-β treatment,the cells became dispersed and spindle in shape.The mRNA expression levels of E-cadherin,Ncadherin,vimentin,and β-catenin in TGF-β group were 0.317,2.475,11.340 and 2.615 folds those in the control group respectively.Western blot showed a marked increase in the expression of N-cadherin,vimentin,and β-catenin proteins but a notable decrease in that of E-cadherin in the TGF-β group compared with the control group.Conclusions TGF-β can induce EMT in A431 cells,and increased expression of TGF-β may contribute to the invasion and metastasis of SCC.

Objective To evaluate the factors influencing prognosis and to explore the pathological mechanism in which herpes simplex virus encephalitis(HSE) was one of the severe types of acute viral encephalitis in children and had poor prognosis.Methods Twenty-one children with HSE were diagnosed by the clinical syndrome of focal encephalitis and HSV DNA-PCR positive in cerebrospinal fluid(CSF) from Jan.2012 to Oct.2013,among whom,19 patients were treated with intravenous Acyclovir,30 mg/(kg · d) 48 hours after onset and were followed up for 6 to 24 months.Clinical data were collected including Glasgow Coma Score,the brain magnetic resonance imaging(MRI),and electroencephalography(EEG).All MRI examinations including plain scan and contrast enhancement were carried out at the beginning of admission and 1 month after the onset of symptoms.The clinical outcomes were divided into two levels accoming to the severity of the neurological deficit,then the data were analyzed by using Logistic regression and Fisher's exact probability method.The OR value was calculated.Results Eighteen children survived,of whom 5 cases had no neurological deficit(27.8％),3 cases were left with mild impairment(16.7％),and the above 8 cases were thought to have better outcome.Six cases had moderate impairment (33.3％) and 4 cases had severe impairment(22.2％) and 1 child died,and these 11 cases were thought to have worse outcome.Patients aged between 1 month and 10 years,average (2.03 ± 2.23) years old.The mean GCS score was (9.68 ± 2.65) scores,the GCS of the patients were more than 7except for one death child with 3 scores.The multiple factor analysis showed that EEG,age,GCS and the range and character in MRI were significantly correlative to the prognosis(P ＜ 0.05).The single factor analysis illustrated that age 1-4 years old(OR =30,95％ CI 2.066-366.510,P =0.002),GCS ≤ 10 scores(OR =27.518,95％ C1 2.066-366.510,P =0.004)and the wide necrosis existence involving diffuse white matter or deep nuclei of MRI findings (OR =12,95 ％ CI 1.294-111.323,P =0.017) indicated the worse outcome.Conclusions Age,GCS score,nature and damage degree of MRI lesions are the main important factors affecting the prognosis of children's HSE.HSE in children is apt to involve the cortex such as frontal lobe,parietal lobe even diffuse white matter or deep nuclei,which indicates the poor prognosis.
