Objective To investigate the relationship between apolipoprotein E ( ApoE ) gene polymorphism and cerebral infarction patients with different gender and etiological typing. Methods A total of 91 patients with cerebral infarction aged≥60 years ( cerebral infarction group) were enrolled. They were divided into either a large artery atherosclerotic (LAA) stroke group (n=37) or a small artery occlusion (SAO) stroke group (n=54) according to the Trial of Org 10172 in acute stroke treatment (TOAST) classification. A total of 105 age-,sex-,and residence-matched healthy subjects were enrolled as controls. A Nested Allele-Specific Multiplex Polymerase Chain Reaction Method was used to detect the ApoE gene polymorphism. The ApoE gene polymorphism of cerebral infarction of different gender and etiological typing were compared. Results ( 1 ) ApoE Genotypes of E2/2, E2/3, E2/4, E3/3, and E3/4 were detected,but the ApoE E4/4 was not detected. (2) There were no significant differences in the frequencies of ApoE genotypes and each gene carrier frequency between the cerebral infarction group and the control group (all P>0. 05). There was significant difference in ApoE genotype frequencies and each gene carrier frequency of the males between the cerebral infarction group and the control group (P<0. 01,P<0. 05). Both the E3/3 genotype frequency (56. 1%) and ε3 carrier frequency (78. 0%) of the cerebral infarction group were lower than the males of the control group ( 79. 2% and 89. 6% respectively );both the E3/4 genotype frequency (31. 7%) and ε4 carrier frequency (15. 9%) were higher than the control group (7. 5% and 3. 8%respectively). There was no significant differences in the ApoE genotype frequency and gene carrier frequency in female participants between the two groups (all P>0. 05). (3) There were no significant differences in the ApoE genotype frequency and gene carrier frequency among the LAA,SAO,and control groups. There was significant difference in the ApoE genotype frequency and gene carrier frequency in males between the LAA group and the control group (P>0. 01);the genotype frequencies of E2/3 and E3/E3 (6. 7% and 46. 7%),ε2,as well as theε3 carrier frequency (3. 3% and 73. 3%) of LAA were lower than those of the control group (13. 2%,79. 2%,6. 6%,and 89. 6%,respectively);the E3/4 genotype frequency andε4 carrier frequency of the LAA subtype were 46. 7% and 23. 3% respectively. They were all higher than 7. 5% and 3. 8% in the control group. However,there were no significant differences in males among the SAO group,the control group,and the 3 groups of females ( the LAA subtype,SAO subtypes,and the control group) (P>0. 05). Conclusion ε4 gene may be a risk factor for LAA in males. The association of ApoE gene polymorphism with cerebral infarction in females is not found.

3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.

Results Com?pared to the indexes,based on the risk assessment model,stool sample processing was the two steps in the laboratory with high risk of infection and high risk factors,with the combination weights of risk possibility and hazard rating were 0.111 and 0.107, respectively. Conclusion The risk assessment model established is feasible. It can be used to make some suggestions for the re?lated laboratory staff.

Objective To compare the effects of median nerve electrical stimulation on coma patients after traumatic brain injury with different settings. Methods From 2013 to 2015, 161 patients with traumatic brain injury were randomly divided into control group (n=40), experimental group 1 (n=41), experimental group 2 (n=39) and experimental group 3 (n=41). The control group received routine conscious-ness-promoted methods, and the experimental groups received median nerve electrical stimulation with 200μs and 30 Hz, 100 Hz and 50 Hz in sequence, 60 minutes a day for 90 days. They were assessed with Glasgow Coma Scale (GCS) and Coma Recovery Scale-Revised (CRS-R) before, 30 days and 90 days after treatment. Results There was significant difference in the scores of CCS and CRS-R, times of treatment, number of sobered patients and coma time among groups (P<0.01), that the experimental groups were better than the control group (P<0.05), and no significant difference was found between the experimental groups 1 and 2 (P>0.05). The experimental group 3 was better than the experimental groups 1 and 2 (P<0.05). Conclusion Median nerve electrical stimulation with 200μs, 50 Hz could promote co-ma patients to wake up optimally.
