Objective To compare efficacy and side effects of intravenous versus oral indomethacin treatment for symptomatic patent ductus arteriosus (PDA) in preterm infants.Methods Fourty-nine preterm infants were reviewed retrospectively who were diagnosed as having symptomatic PDA confirmed by echocardiography.According to the using type and approach that were divided into 2 groups (intravenous group,n=21;oral group,n=28) and their doses and intervals were same.The rates of ductal closure and side effects were compared in 2 groups.Results There were no significantly different between 2 groups in single ductal closure and complicating other diseases. Soon closure of intravenous group was higher significantly than oral group [61.9 %(13/21) vs 28.6 %(8/28),P

Objective:To investigate the feasibility of dynamic turbidity method for the detection of bacterial endotoxin content in influenza split vaccine. Methods: According to the bacterial endotoxin detection method described in general rule 1143 in Chinese Pharmacopoeia (2015 edition), the reliability test for standard curves of influenza split vaccine, the interference initial screening test, the interference verification test and the endotoxin content were performed or determined, and the results were compared with those by the gel method for the same batches of vaccine. Results:The results of reliability test for standard curves were accordance with the reg-ulations. In the interference initial screening test, vaccine was diluted by 160 times, 320 times and 640 times, and the recovery was between 50% and 200%, which showed no interference. The results of the interference verification test further proved that vaccine with 640 times dilution had no interference effect on test. The bacterial endotoxin contents of 10 batches of influenza split vaccine deter-mined by the turbidity method were less than the limit value of 20 EU·ml-1 , and the results were the same as those determined by the gel method. Conclusion:It is feasible to detect the content of bacterial endotoxin in influenza split vaccine by the dynamic turbidity method, which is worthy of promoted application.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

Objective To assess the effectiveness of absorbable screws and metallic devices for treating tibial plateau fractures.Methods Fifty-seven cases of tibial plateau fractures were treated with internal fixation using absorbable screws(Group A),cannulated screws(Group B)and condylar buttress plates(Group C)in our hospital.According to Schatzker classification,there were 15 cases with typeⅠfractures,21 with typeⅡ,nine with typeⅢand 12 with typeⅣ,who were followed up for 6-51 months. Statistical analysis was performed to compare bone union and functional restoration of the knee between three groups.Results Bone union was achieved in all cases.Based on Merchant scale for knee func- tion,excellence rate was 84%(16/19)for Group A,92%(11/12)for Group B and 85%(22/26) for Group C,with no significant statistical difference.Conclusion Absorbable screws is as effective as metallic devices for treating tibial plateau fractures and has advantages of minimal invasion,few complica- tions and avoiding secondary operation.

Objective To explore the possible factors associated with twice human brucellosis epidemics in Inner Mongolia during 1952 to 2007 to provide scientific tactics for prevention and control brucellosis. Methods Surveillance data and literature about human brucellosis during 1952 to 2007 in Inner Mongolia was collected, descriptive analysis of human brucellosis incidence on distribution in the regions and among occupations was carried out during 1952 to 2007. Results In Inner Mongolia, the first epidemic of human brucellosis peak appeared in the early 1960s, spreading to 12 regions, at an incidence of 55.28/100 000 in 1961, 72.9% of the Brucella infected people were herdsman;another epidemic peak seriously hit middle and eastern regions after 2000, the incidence being 38.44/100 000 in 2005;51.9% and 28.7% of the new brucellosis cases were respectively peasant and herdsman. Conclusions In Inner Mongolia, animal husbandry industry has been rapid developed since the early 1990's, resulting frequent livestock trade without quarantine, at the same time the public health system doesn't match the development, so the epidemic situation of brucellosisbecomes more and more serious after mid-90's, and has reached the peak during 2004 and 2007.

Objective To explore the effects of under-expression of large tumor suppressor 1 (LATS1) on activation of Hippo signaling pathway and differentiation, proliferation, migration of bone marrow mesenchymal stem cells (mMSCs) of micein vitro.Methods mMSCs of C57BL/6 mice were divided into normal control (MSC) group, empty vector control (MSC-GFP) group, LATS1-over-expressing (MSC-LATS1) group, empty vector without LATS1 shRNA control (MSC-shControl) group and LATS1-under-expressing (MSC-shLATS1) group. Lentiviral vectors with activated,inactivated LATS1 (the key molecule of Hippo signaling pathway) modifications and empty vectors were constructed and were used to infect mMSCsin vitro. The transduction efficiencies mediated by the lentiviral vectors were evaluated by fluorescence microscopy and flow cytometry. The mRNA expression of LATS1 was quantified by quantitative real-time polymerase chain reaction (qRT-PCR), and the protein expressions of LATS1, YAP (p-YAP), 14-3-3 were quantified by Western Blot to evaluate the activation of Hippo signaling pathway. Osteogenic and adipogenic differentiation of mMSCs were evaluated through measurement of Runx2, OSX and C/EBPα, PPAR-γ mRNA by qRT-PCR, as well as Alizarin Red S and Oil red O staining. Proliferation of mMSCs was evaluated using methy thiazdyl tetrazolium (MTT) assay. The scratch test and Transwell chamber test were used to analyze the horizontal and vertical migration ability of mMSCs.Results The transduction efficiencies mediated by the lentiviral vectors were 94.74%-96.10%.
