Objective To investigate the usage of antiepileptic drugs (AEDs),epileptic seizures,pregnancy outcomes and infant feeding practices among pregnant women with epilepsy,and provide scientific evidence for eugenics.Methods The clinical characteristics of 350 pregnant women with epilepsy from Shaanxi Provincial Epilepsy & Pregnancy Register from October 2012 to July 2016 were analyzed retrospectively.Results A total of 350 patients with 376 pregnancies were included in the final analysis.Among 376 pregnancies,272 pregnancies (72.3％) were under the treatment of AEDs.Of them,246 pregnancies (90.4％) were on monotherapy,26 (9.6％) on polytherapy.Only patients during 179 pregnancies (47.6％) took folic acid in the first trimester.Seizure frequency increased in patients during 123 pregnancies (32.7％),of whom patients during 43 pregnancies (35.0％) did not use AEDs.Although other patients during 80 pregnancies (65.0％) took AEDs,regular pharmacokinetic monitoring was absent.A total of 170 pregnancies (45.2％) attained seizure-free.Seizure frequency decreased in 42 pregnancies (11.2％) and remained unchanged in 24 pregnancies (6.4％).The rates of cesarean section and natural delivery were 43.8％ (158/361) and 56.2％ (203/361),respectively.Totally 4.5％ (17/376) pregnancies had adverse pregnancy outcome,and 1.9％ (7/376) had fetal malformations.The most common congenital malformation was heart malformation,which was observed in two offspring.One offspring developed dysostosis,one developed chromosome abnormality,and another developed cerebellum deformity.In addition,one twin developed conjoined deformities.Breastfeeding rate was 52.6％ (190/361).Conclusions In Shaanxi province,AEDs compliance,pharmacokinetic monitoring and usage rate of folic acid still need to be improved in pregnant women with epilepsy.Clinical trial registration Chinese Clinical Trial Registry,ChiCTR-OOC-16009277

Objective: To explore the effect of Laminarina Japonica Polysaccharides (LJPS) on blood glucose in diabetes mice.Methods: Effect of LJPS on alloxan inducing diabetes mellitus model was investigated by applying different doses(125,250 and 500mg/kg bw).Results: The doses of LJPS were able to lower blood glucose level by 34.96%,20.70% and 26.82% respectively. They also decreased BUN level, enhanced liver glycogen, calcium in serum and insulin concentration. LJPS could restore the injury of alloxan induced pancreas islet significantly by histopathological findingConclusion: The results show that LJPS is an active component in protecting against alloxan induced pancreas injury and mediating the blood glucose level.

AIM To investigate actions of total paeony glycoside(TPG) on learning and memory capacity and related products of metabolism of senile mice induced by D galactose. METHODS The subacute senile mouse models induced by injection of D galactose subcutaneously were used. RESULTS TPG could improve the learning and memory capacity of model mice in shuttle test and enhance spatial resolution in water maze test. TPG not only reduced the content of monoamine oxidase(MAO) and inhibited the decrease of cholinesterase(CHE) significantly, but also lessened the level of malondialdehyde(MDA) and inhibited the decrease of superoxide dismutase(SOD) in cerebrum of model mice. TPG still promoted the recovery of lobar atrophy and hypoimmunity of senile mice remarkedly. CONCLUSION TPG possesses obvious effects of improvement on learning, spatial resolution and delaying senility.

Objective To investigate the energy intake and complications of continuous and intermittent pump feeding in acute stroke patients and provide a theoretical evidence to support for clinical treatment.Methods From April 2012 to June 2016,69 acute srtoke patients on the nasogastric tube feeding and admitted in the Department of Neurology intensive care unit in Xijing Hospital were enrolled and randomly assigned to have continuous or intermittent pump feeding.The primary endpoint was the efficacy in supplying the desired amount of nutrients by the fifth day and complications(hospital-acquired pneumonia,diarrhea,gastric retention,gastrointestinal bleeding)during the first week.The secondary endpoint was nutritional assessments(albumin,prealbumin,transferrin,hypersensitive c-reactive protein)in the first week.Results Both groups were comparable in acute physiology and chronic health evaluation Ⅱ(13.3±4.7 vs.12.9±4.5),Glasgow coma scale[10(7.2,14)vs.9.5(7.7,12)],National Institute of Health stroke scale[17(15,19)vs.16(13,20)],and Barthel scores[5(0,12.5)vs.10(5,15)](all P>0.05).It was no significantly different in the achievement percentage of the energy determined in the fifth day [93.9％(77.9％,99.8％)in continuous group and 84.8％(75.7％,93.9％)in intermittent group(U=0.144,P>0.05).Intermittent pump feeding significantly reduced the rate of hospital-acquired pneumonia in the first week when compared with continuous pump feeding(58.3％vs.33.3％,X2=4.327,P=0.038),and both groups displayed a moderate number of digestive complications without significant differences,including diarrhea(30.6％vs.27.3％,X2=0.09,P=0.764),gastric retention(2.78％vs.3.03％,X2=0.001,P=1.000),and gastrointestinal bleeding(5.56％vs.9.10％,X2=0.010,P=0.920).No difference could be demonstrated in serum protein markers between two groups in the first week,including prealbumin[0.17(0.13,0.20)g/L vs.0.18(0.15,0.24)g/L,P=0.195),transferrin[1.90(1.52,2.20)g/L vs.1.94(1.65,2.06)g/L,P=0.747),and hypersensitive C-reactive protein[22.5(8.3,50.1)mg/L vs.14.6(6.5,30.5)mg/L,P=0.205].Conclusions Both continuous and intermittent pump feeding can reach the target predictive nutrition(100％of calculated caloric requirements)without statistical differences in the incidences of gastrointestinal complications,and the rate of HAP is lower in intermittent group.Intermittent enteral nutrition can be used as an appropriate method of enteral nutrition support to improve the nutritional status in critically acute stroke patients.

Objective To observe the antimicrobial effect of a kind of Chinese medicine Qingre compound preparation on the common pathogenic bacteria of upper respiratory tract infection (URTI). Methods A total of 163 common pathogen?ic bacteria of URTI was selected in this study, including 74 non extended-spectrum β- lactamases (ESBLs)-producing Gram-negative bacteria (33 Escherichia coli, 24 Klebsiella pneumonia and 17 Pseudomonas aeruginosa), 10 ESBLs-produc?ing Gram-negative bacteria (6 Escherichia coli and 4 Klebsiella pneumoniae) and 79 Gram-positive bacteria [11 methicil?lin-resistant Staphylococcus aureus (MRSA), 46 methicillin-sensitive Staphylococcus aureus and 22 Streptococcus pneu?moniae]. Agar dilution method was adopted to perform the quantitative drug sensibility test. Agar plates that contained differ?ent concentrations of Qingre compound preparation were prepared. The bacterial suspension was planted on the plates. Then we observed the plates after incubation, and recorded the minimum inhibitory concentration (MIC). Results The antimicro?bial rates of Qingre compound preparation were 88, 176 and 22 g/L for MIC90 of Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. The antimicrobial effects of Qingre compound preparation were coincident on the MIC 90 of ES?BLs-producing strains and non ESBLs-producing strains. The accumulated antibacterial rates of different concentrations of medicine to Pseudomonas aeruginosa were the highest. The MIC90 values of Qingre compound preparation were 11, 11 and 22 g/L for MSSA, MRSA and Streptococcus pneumoniae. The MIC90 of MRSA was coincident with MSSA, but MIC50 of MRSA was slightly higher than that of MSSA. The accumulated antibacterial rates of different concentrations of medi cine to MSSA and MRSA were all higher than those of Streptococcus pneumonia. The accumulated antibacterial rate of MSSA was similar with that of MRSA. Conclusion The Chinese medicine Qingre compound preparation could restrain common patho?genic bacteria of URTI except Klebsiella pneumoniae. The antibacterial effect of Qingre compound preparation is significant?ly better in Ggram-positive bacteria than that of Gram-negative bacteria.

To obtain active protein of pIL-18 expression in Lactococcus lactis, and to observe its biological activity, the total RNA was extracted as template from peripheral blood mononuclear cells. Porcine interleukin 18 (pIL-18) was amplified by RT-PCR. The resulting fragment was cloned into pAMJ399 L. lactis vector, and then transformed to L. lactis MG1363 cells by electroporation. Expression of pIL-18 protein was detected by SDS-PAGE and Western-blotting. Bioactivity of the product was tested by pig spleen lymphocyte proliferation test and cytopathogenic effect inhibition assay. The result of Western blotting and bioactivity test shows that the molecular weight of pIL-18 protein was 19 kDa. The react line was observed in both supernatant and precipitated of the recombinant bacteria pAMJ399-pIL18/MG1363. The expressed pIL-18 can promote the proliferation of pig spleen lymphocyte, and significantly inhibit virus multiplication. As conclusion, porcine interleukin-18 was successfully expressed in L. lactis, and the product was biologically active.

Objective: To analyze the association between hepatitis B virus (HBV) infection and pancreatic cancer. Methods: Retrospective analysis was performed to explore the positive rate of serum hepatitis B virus surface antigen (HBsAg) in patients with pancreatic cancer, lung cancer, diabetes mellitus and general population. Z test was used to compare the rate of HBV infection between the samples and general population. The rates among the samples were compared by Chi-square test. Results: A total of 3,701 registered patients seen in our hospital between January 1st 2003 and March 31st 2009 were collected. There were 230 pancreatic cancer patients with a positive rate of serum HBsAg of 16.1%, 1,188 lung cancer patients with a positive rate of serum HBsAg of 10.7%, and 2,283 patients with diabetes mellitus with a positive rate of serum HBsAg of 11.6%. There was no statistical significance in Z-test results between lung cancer patients and general population (Z=1.104, P=0.163), but the Z-test results between patients with diabetes mellitus and general population showed a statistical significance (Z=2.98, P=0.002). The positive rate of HBsAg was higher in pancreatic cancer patients than that in lung cancer patients (OR=1.60, 95% Cl: 1.077-2.382, r=5.487, P=0.019). Similar results were found between pancreatic cancer patients and diabetic patients (OR=1.46, 95% CI: 1.004-2.123, r=3.965, P=0.046). Conclusion: The positive rate of HBsAg is high in pancreatic cancer patients. There might be an association between HBV infection and pancreatic cancer.
