Objective:To investigate the correlation of fluid-attenuation inversion recovery (FLAIR) vascular hyperintensity (FVH) and clinical outcome in patients with middle cerebral artery M1 occlusive stroke.Methods:Patients with acute middle cerebral artery M1 occlusive stroke admitted to the Department of Neurology, the Second Affiliated Hospital of Anhui Medical University from June 2018 to September 2019 were enrolled retrospectively. The demographic and clinical data were collected. Diffusion-weighted imaging (DWI)-Alberta Stroke Program Early CT Score (ASPECTS) and FVH score were performed with MRI images. The modified Rankin Scale (MRS) was used to evaluate the clinical outcome at 90 d after onset. 0-2 was defined as good outcome, and >2 was defined as poor outcome. Multivariate logistic regression analysis was used to determine the independent correlation between FVH and the outcome. Results:A total of 65 patients with acute middle cerebral artery M1 occlusive stroke were enrolled, including 37 males (56.9%). Their age was 64.35±12.13 years. Twenty-nine patients (44.6%) had a good outcome, and 36 (55.4%) had a poor outcome. There were significant differences in triglyceride ( P=0.037), antihypertensive drug treatment ( P=0.037), baseline National Institutes of Health Stroke Scale (NIHSS) score ( P<0.001), DWI-ASPECTS ( P=0.017) and FVH score ( P<0.001) between the poor outcome group and the good outcome group. Multivariate logistic regression analysis showed that FVH score (odds ratio 6.477, 95% confidence interval 1.570-26.716; P=0.010) and NIHSS score (odds ratio 1.869, 95% confidence interval 1.326-2.635; P<0.001) were significantly independently correlated with the poor outcome. However, there was no significant independent correlation between DWI-ASPECTS and the outcome (odds ratio 0.451, 95% confidence interval 0.068-2.988; P=0.410). Conclusions:FVH score is an independent risk factor for poor outcome in patients with acute middle cerebral artery M1 occlusive stroke.

Objective To analyze the outcome of patients receiving intrauterine insemination with husband sperm,in order to evaluate the effect of relative factors on pregnancy rate after intrauterine insemination. Methods Ninety-eight infertile couples who received intrauterine insemination in the Affiliated Hospital of Nantong University from March 2013 to May 2014 were selected as our subjects and 181 cycles were included. The information including clinical factors including maternal age,infertile time,infertile causes, ovulation induction protocol,time of insemination and postwash total motitle sperm(TMS)and pregnancy rate were recorded. Results (1)Totally 26 patients received clinical pregnancies,and clinical pregnancy rate(CPR) was 14. 36% per cycle. With age increase pregnancy rate decreased( χ2 = 1. 654 9,P = 0. 647).(2)The pregnancy rate of the patients was the same within the infertile time( χ2 = 1. 588 5,P = 0. 662).(3)The pregnancy rate of the patients with secondary infertility was lower than that of the patients with primary infertility,but there was no significant difference(χ2 = 0. 923 3,P = 0. 337).(4)The pregnancy rate of ovulation induction cycles was lower than that of nature cycles,but there was no significant difference(χ2 = 2. 222 0,P= 0. 136).(5)Postwash TMS was showed the same trend(χ2 = 0. 643 4,P = 0. 422). Conclusion In terms of intrauterine insemination with husband sperm,age,infertile time,infertile types,ovulation induction protocol and posrwash TMS can affect pregnancy rate,and the effects of various factors should be considered comprehensively in the process of therapy.

Objective To explore the correlation between nursing document marking system (NCR-11) and APACHE Ⅲ score, and evaluate the value of NCR-11 for the assessment of critical care patients. Methods From March 1st to September 30th, 2013, 97 inpatients in ICU were chosen as sampling prospectively and were collected their clinical medical information. NCR-11 was calculated from next day to the sixth day of hospitalization and all patients were divided into two groups according to APACHE Ⅲ score: <60 score ( A group ) , ≥60 score ( B group ) , then statistically analyzed the correlation between NCR-11 and APACHE Ⅲ score and compared the difference between A and B group. Results The A group obtained the score of NCR-11 (52. 63 ± 10. 66), which had positive correlation with APACHE Ⅲ score (r=0. 619,P<0. 01), while B group acquired (56. 88 ± 9. 34) and correlation coefficent with APACHE Ⅲ score was r =0. 283,P<0. 01. The score of NCR-11 in B group was higher than that of A group (F=4. 873,P<0. 01), but the change of A and B group had no statistical significance from 5 days assessment (F=0. 096,P>0. 05). Conclusions NCR-11 and APACHE Ⅲ score has a certain correlation and could reflect the severity of the disease indirectly. It has some value in evaluating the severity of critical care patients.

AIM: To gain cdcSTBX25A-fas chimeric gene bearing the regulative fragment cdcSTBX25A and opening read frame of fas in order to construct and identify eukaryotic expression vectors, pAdTrack-CMV-cdcSTBX25A-fas and pAdTrack-cdcSTBX25A-fas, which have the potential to transfer the tumor proliferative signal to promoting-apoptosis signal through up-regulate the fas expression by c-myc. METHODS: A pair of primers were designed according to the known sequences of cdcSTBX25A and fas. The cdcSTBX25A-fas chimeric gene was obtained by PCR reaction and inserted into the two plasmids pAdTrack-CMV and pAdTrack, respectively. The two recombinant plasmids were transferred into E. coli DH5?. The positive clones were screened in LB media with 50 mg/L kanamycin and identified by agarose gel electrophoresis, endonuclease digestion and PCR. The nucleotide sequence of inserted cdcSTBX25A-fas was determined by dideoxy chain termination method. Using software, BLAST was conducted to analyze the structure and sequence of the target fragments and compared with GenBank. RESULTS: The chimeric target gene, cdcSTBX25A-fas, of 1 603 bp was obtained. The positive host bacteria E. coli DH5? of recombinant plasmids were screened and amplified. The double-enzyme digestion showed the pAdTrack-CMV-cdcSTBX25A-fas and pAdTrack-cdcSTBX25A-fas presenting 9.2 kb, 1.6 kb bands, and 8.3 kb, 1.6 kb bands respectively. The sequence analysis confirmed that the two shuttle plasmids containing 1 597 bp cdcSTBX25A-fas with the ORF of fas. CONCLUSION: The eukaryotic expression plasmids pAd-Track-CMV-cdcSTBX25A-fas and pAdTrack-cdcSTBX25A-fas were successfully constructed.
