Ebola virus-related papers covered in PubMed and CNKI were analyzed by co-occurrence and cluster analysis, respectively. The current situation in research of Ebola virus in China and foreign countries was com-pared. Some suggestions were proposed for research of Ebola virus in China, such as attaching importance to re-search of Ebola virus, enforcing research of its vaccine,and strengthening cooperation between domestic and foreign scholars.

Objective To evaluate the anti-tumour effect of 60℃ LipiodoI in the embolization of VX_2 hepatocarcinoma in rabbits.Methods VX_2 carcinoma cells were surgically implanted into the left liver lobe in 30 male New Zealand white rabbits,which were randomly divided into 3 groups by figure and table method with 10 rabbits in each group.Physiological saline,Lipiodol(37℃),and Lipiodol(60℃)were injected in each group via hepatic artery and liver cancer was embolized.The volume of tumour and serum level of aspartate aminotransferase(AST)were observed after one week,and the survival period of VX_2 rabbits was also observed.Results In the group of Lipiodol(60℃),the growth rate of tumour(0.92? 0.21)was significantly lower than that of control group(3.48?1.17)and Lipiodol(37℃)groups (1.69?0.26),respectively(F=34.95,P0.05),but was significantly higher than the control group(68.6?6.6)U/L(t=19.24,P

Objective To observe the changes on the neurogenic inflammation-related factors in the dura mater of the rat model of migraine and investigate the possible mechanism of the pain of migraine.Methods SD rats were randomly divided into stimulation group ( n = 32 ) and sham group ( n = 32 ).Unilateral trigeminal ganglion was stimulated to induce migraine for rats in the stimulation group. Rats in the sham group were subjected to sham surgery. The levels of calcitonin gene-related peptide (CGRP) in the blood of jugular vein in the stimulation side were measured by radioimmunoassay. The levels of histamine in peripheral blood and prostaglandin E2 (PGE2 ) in the dura mater were determined by enzyme-linked immunosorbent assay (ELISA). The number of mast cells and percentage of their degranulation in the dura mater were determined under a microscope after toluidine blue staining. Cyclooxygenase 2 (COX-2)expression in the dura mater was evaluated by immunohistochemical staining and western blot analysis. Results In the stimulation group, the level of CGRP in the ipsilateral jugular vein was (82. 84 ± 16. 24)pg/ml and in the sham group was (59. 20 ±11.66) pg/ml (t = -3.34, P ＜ 0. 05 ). The level of histamine in the ipsilateral jugular vein was ( 11.59 ± 1.20) ng/ml and in the sham group was (9. 87 ±0. 88) ng/ml (t = - 3. 27, P ＜ 0. 05). The number of mast cells in the dura mater decreased from 15.46 ± 2. 40 in the stimulation group to 11.63 ± 1.67 in the sham group ( t = 3.71, P ＜ 0. 05 ). Degranulation of mast cells in the dura mater significantly increased from 14. 09% ±4. 53% in the sham group to 29. 10% ±9. 39% in the stimulation group (t = - 4. 07, P ＜ 0. 05 ). The level of PGE2 in the stimulation group was ( 382. 30 ±20. 90) pg/ml and in the sham group was (80. 70 ± 10. 60) pg/ml (t = - 16. 674, P ＜0. 05). The number of COX-2 positive cells significantly increased from 42. 00 ± 18.40 in the sham group to 139.00 ±20. 50 in the stimulation group (t = -7. 994, P ＜0. 05). Also the COX-2 protein level was elevated from 19. 50 ±9. 20 in the sham group to 359. 20 ±21.90 in the stimulation group (t = -5. 190, P ＜0. 05). Conclusions Electrical stimulation on the unilateral trigeminal ganglion induces neurogenic inflammation in the dura mater. Changes on the neurogenic inflammation-related factors are probably the essential pathophysiological mechanism underlying the pain in migraine.

Objective To study the changes in the immune function of advanced hepatic carcinoma patients after thermochemoembo-lization via hepatic artery. Methods Forty advanced hepatic carcinoma patients were randomized divided into 2 groups. A group (n=20) was treated by perfusion with ADM(40mg) + MMC(10mg) in 37℃ 9% sodium chloride solution via hepatic artery, and B group (n=20) was treated by perfusion with ADM(40mg) + MMC(10mg) in 60℃ 9% sodium chloride solution via hepatic artery, then all were embolized with some quantity of lipiodol. Flow cytometry (FCM) was used to detect the changes in percentages of T-lymphocyte subsets (CD3<'3, CD4<'+, CD8<'+) and NK cells, and the contents of soluble interleukin-2 receptor (sIL-2R) were detected by double sandwich ELISA before and after therapy. LDH enzyme-release assay was used to detect cytotoxic activity of NK cells. Results Compared with pre-therapy group or A group after therapy, the percentage of CD4<'+ cells of B group after therapy significantly increased (P<0.05), the percentages of CD8<'+ cells and the content of sIL-2R of B group after therapy markedly decreased (P<0.05). The percentages of NK cells and cytotoxic activity NK cells of B group after therapy were significantly higher than those from pre-therapy group or A group (P<0.05). Conclusion Intra-arterial thermochemoembolization may activate and improve cell-mediated immune function with a certain degree.

Objective To investigate the distribution of homeostasis model assessment-insulin resistance(HOMA-IR)index and its relationship with metabolic syndrome and inflammatory cytokines in students aged 7 to 14 years. Methods The data of 366 students(n=163 for boys and n=203 for girls) aged 7 to 14 years were collected,including anthropometric parameters (height,body weight,body mass index,waist circumference,hip circumference and waist-hip ratio),blood pressure,total fat mass,fat proportion,fasting blood lipid,fasting blood glucose,fasting insulin and serum levels of inflammatory cytokines such as tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)and interleukin-6(IL-6),and insulin resistance was evaluated by HOMA-IR index. Results The 75 th percentile of HOMA-IR index for boys and girls was 3.62 and 2.88,respectively.Body weight,height,body mass index,waist circumference,hip circumference,total fat mass and fat proportion were positively related to HOMA-IR index(P<0.01).When HOMA-IR index surpassed 75th percentile,age,anthropometric parameters,total fat mass,fat proportion and systolic blood pressure significantly increased in boy and girl students(P<0.05),no significant change occurred in diastolic blood pressure in boy and girl students,the levels of serum TNF-α and IL-6 significantly increased in boy students(P<0.05),while there was no significant change in level of CRP in boy students and levels of CRP.TNF-α and IL-6 in girl students. Conclusion The increase of HOMA-IR index leads to a dramatic increase of anthropometrie parameters,total fat mass,fat proportion and serum TNF-α and IL-6 in boy students,while that results in the increase of anthropometric parameters,total fat mass and fat proportion in sid students,with no significant change in serum inflammatory cytokines.

This study was aimed to develop an HPLC method for the determination of hesperidin,magnolol,honoki-oland liquiritin in Soft Capsule Jia-Wei Huo-Xiang Zheng-Qi (JWHXZQ). AKromasil C18 column (250 mmí4.6 mm, 5 μm) was used with water-methanol as mobile phasegradient elution. The flow rate was 1.0 mL·min-1, and the de-tecting wavelength was at 287 nm. The results showed that the linearity ranges ofhesperidin,magnolol,honokioland liquiritinwere 4.47-178.70 μg·mL-1, 3.42-136.96 μg·mL-1, 3.49-139.48 μg·mL-1, 3.92-157.20 μg·mL-1, respec-tively (r>0.999). The average recoveries of them were 99.48%, 99.05%, 99.57% and 99.79%, respectively. It was concluded that the method was accurate, sensitive and specific for quality control of Soft Capsule JWHXZQ.

Objective To investigate the molecule phenotype, epidemiology, and resistance genes of the New Delhi metallo- β-lactamase-1 ( NDM-1 ) producing Klebsiella pneumoniae ( K. pneumoniae ) . Methods Retrospective study was made on one hundred and ten non-repetitive carbepenem-resistant K. pneumoniae clinical isolated strains, which were collected from January 2011 to December 2012 in our hospital. The minimal inhibitory concentrations ( MICs ) of antibiotics were tested by the GN13 cards of BioMerieux Company. Modified Hodge test were used for the detection of carbapenemases. The blaNDM-1 encoding gene and linkage of ISAba125-NDM were detected by PCR method. The purified PCR products were cloned and sequenced. The homology of the K. pneumoniae were analyzed by the multilocus sequence typing ( MLST ) . Plasmid conjugation experiment and curing method were used to study the transfer of bacterial resistance. The Fisher′s exact probability test was used to compare the data. Results 13% NDM-1-producing K. pneumoniae were detected and confirmed as blaNDM-1 by sequencing (14/110). The resistance rates of the 14 NDM-1-producing K. pneumoniae strains to imipenem, meropenem, ertapenem, ciprofloxacin, levofloxacin, amikacin, and aztreonam were 14/14, 14/14, 13/14, 10/14, 9/14, 5/14, and 11/14. Meanwhile, the positive rate of ISAba125-NDM linkage of those 14 NDM-1-producing K. pneumoniae strains was 14/14. The E. coli J53 transconjugants, whose MICs of imipenem, meropenem, and ertapenem were increased by 4 to 64 times, were blaNDM-1 gene and ISAba125-NDM linkage positive. In addition, it was showed that the blaNDM-1 gene and ISAba125-NDM linkage were located on a plasmid with a size of approximately 65 000 bp. Conclusions The NDM-1 producing K. pneumoniae strains in this study were resistant to many commonly used antibiotics, however, the resistance rate to aminoglycoside and aztreonam were relatively low. The carbapenemase-resistant genotype spread by blaNDM-1 carried plasmid. Attention should be paid to its easily transmissible feature among the strains in clinic. The insertion sequence ISAba125 may be involved in the blaNDM-1 gene mediated carbapenemase-resistant genotype.

The activity of matrix metalloproteinases (MMPs) in the uterine flushing and endometrial tissue of normal adult women wearing FCu-IUD (fixed Cu-IUD) or FICu-IUD (indomethacin-releasing FCu-IUD) was observed by using zymography on SDS-PAGE containing gelatin. The results showed that the activity and kinds of MMPs in FCu-IUD group were increased significantly as compared with themselves before being inserted FCu-IUD. However, compared with the FCu-IUD group, the activity of some kinds of MMPs in the FICu-IUD group was decreased significantly. These data suggest that IUD can enhance the activity of MMPs in human endometrium, intermediated by prostaglandins, and MMPs may have relation to IUD-induced menorrhagia and indomethacin reduces IUD-induced menorrhagia by partly inhibiting MMPs synthesis.
