Objective To compare the clinic features of neuromyelitis optica (NMO) and multiple sclerosis(MS).To compare the positive rate of NMO-IgG in NMO,MS and other related diseases,and determine whether it can be considered as a biomarker for differential diagnosis.Methods Detected serum NMO-IgG in 34 NMO patients,22 MS patients,24 high risk syndrome,5 clinical isolated syndrome,and 35 patients with other neumlogical diseases.Compared the clinic features(onset age,severity,prognosis,MRI lesions,autoimmune antibodies,CSF)of 34 NMO patients and 22 MS patients.Results The onset age of NMO is older than that of MS.It is more severe and with worse prognosis than MS.Longitudinal spinal cord lesions are easily found in NMO.NMO-IgG positive rate in NMO and high risk syndrome patients are 58.8% (20/34)and 45.8%(11/24)respectively,which are higher than that in MS(1/22),clinical isolated syndrome(1/5)and other neurological diseases(1/35;x2=37.2,P<0.01).The positive rate may have a relationship with the length of spinal cord lesions.Condusions MS and NMO are probably different diseases.NMO-IgG positive rate in NMO is significandy higher than that in MS,it can be considered as a biomarker for differential diagnosis.

0.05).Cmax of domestic and imported rebamipide tablet were (0.56?0.24) and (0.59?0.29)mg?L-1, with that tmax were (1.75?0.92) and (1.98?1.05)h,t1/2(?) were (1.86?1.38) and (1.93?1.45)h,AUC0～∞ were (2.48?1.06) and (2.62?1.35)mg?h?L-1. Conclusion The pharmacokinetics of the two products are similar.

Objective To upregulate Notch signaling in cancer cells by overexpression of active part of Notch1 and to examine the proliferation of the cells. Methods Four cancer cell lines were infected with retrovirus recombined with sequence encoding active part of Notch1.CBF-1 reporter plasmid was used to detect Notch signaling and proliferation assay was carried out by MTS method.Cell cycle analysis was synchronously conducted. Results The overexpression of the active part of Notch1 induced upregulation of Notch signaling,led to growth inhibition in Hela and HepG2 cell lines and growth boost in BGC-823 cell lines,while had no effect on Chang cell lines. Conclusion The upregulation of Notch signaling can exert various effects on different cancer cell lines which is critical to the gene therapy for cancers.

OBJECTIVETo study the diagnostic value of diffusion tensor imaging (DTI) in cervical spondylotic myelopathy.

METHODSTwenty healthy volunteers and fifty patients with cervical spondylotic myelopathy underwent DTI in the Affiliated Hospital of Medical College of Ningbo University from January 2014 to April 2015. Healthy volunteers served as controls. Fifty patients were divided into three groups (group A , B, C) according to cervical MRI scan standard. Group A (17 cases) had only the dura mater spinalis compressed; Group B (23 cases) showed the cervical spinal cord compressed, but no high signal in it; Group C (10 cases) had the cervical spinal cord compressed with high signal in the same level. The average apparent diffusion coefficients(ADC) and fractional anisotropy (FA)values in these examinee were analyzed and all subjects were performed fiber tracking.

RESULTSThere was no statistically significant differences in ADC and FA values in C2/C3, C3/C4, C4/C5, C5/C6, C6/C7 of control group (P>0.05). The average ADC and FA values in control group were (0.875 +/- 0.096) x10(3) mm2/s and 0.720 +/- 0.051, respectively; compared with group A,there was no statistically significant difference; compared with group B and C, there was significant difference; comparison among group A, B, C, there was significant differences.

CONCLUSIONDTI can early and accurately quantify the changes of microstructure in cervical spondylotic myelopathy. Fiber tracking can show the damage range of spinal cord lesions.

OBJECTIVE: To extract sperm DNA from mixed stain by the modified differential lysis method combined with silicon bead method and to evaluate its application value. METHODS: Fifty-two mixed stains containing female STR genotypes detected by differential lysis method were collected. The sperm DNA was extracted by the modified method combined with silicon bead method, then genotyped with the Identifiler Kit, and compared with the results of genotyping by the conventional differential lysis method as control. RESULTS: Of the 52 samples, 38 samples with sole male STR genotypes in all loci were detected. The detection rate of male STR genotypes was 98.08% through the modified method combined with silicon bead method. CONCLUSION The modified differential lysis method combined with silicon bead method can be used in extraction of sperm DNA from mixed stain.

BACKGROUND: This study aimed to observe the effect of early goal directed therapy (EGDT) on tissue perfusion, microcirculation and tissue oxygenation in patients with septic shock. METHODS: Patients with early septic shock (<24 hours) who had been admitted to the ICU of Zhongda Hospital Affiliated to Southeast University from September 2009 through May 2011 were enrolled (research time: 12 months), and they didn't meet the criteria of EGDT. Patients who had one of the following were excluded: stroke, brain injury, other types of shock, severe heart failure, acute myocardial infarction, age below 18 years, pregnancy, end-stage disease, cardiac arrest, extensive burns, oral bleeding, difficulty in opening the mouth, and the onset of septic shock beyond 24 hours. Patients treated with the standard protocol of EGDT were included. Transcutaneous pressure of oxygen and carbon dioxide (PtcO2, PtcCO2) were monitored and hemodynamic measurements were obtained. Side-stream dark field (SDF) imaging device was applied to obtain sublingual microcirculation. Hemodynamics, tissue oxygen, and sublingual microcirculation were compared before and after EGDT. If the variable meets the normal distribution, Student's t test was applied. Otherwise, Wilcoxon's rank-sum test was used. Correlation between variables was analyzed with Pearson's product-moment correlation coefficient method. RESULTS: Twenty patients were involved, but one patient wasn't analyzed because he didn't meet the EGDT criteria. PtcO2 and PtcCO2 were monitored in 19 patients, of whom sublingual microcirculation was obtained. After EGDT, PtcO2 increased from 62.7±24.0 mmHg to 78.0±30.9 mmHg (P<0.05) and tissue oxygenation index (PtcO2/FiO2) was 110.7±60.4 mmHg before EGDT and 141.6±78.2 mmHg after EGDT (P<0.05). The difference between PtcCO2 and PCO2 decreased significantly after EGDT (P<0.05). The density of perfused small vessels (PPV) and microcirculatory flow index of small vessels (MFI) tended to increase, but there were no significant differences between them (P>0.05). PtcO2, PtcO2/FiO2, and PtcCO2 were not linearly related to central venous saturation, lactate, oxygen delivery, and oxygen consumption (P>0.05). CONCLUSION: Peripheral perfusion was improved after EGDT in patients with septic shock, and it was not exactly reflected by the index of systemic perfusion.
