Objective To investigate the relationship between the single nucleotide polymorphisms(SNPs) of disrupted in schizophrenia 1 (DISC1) gene and autism in Chinese Han children.Methods Genome-wide SNP genotyping was performed by using Illumina HumanHap CNV370-Duo Chip in 278 autistic trios,157 autistic individuals and 435 healthy controls.Genotype data of SNPs within DISC1 gene were selected.The association between these SNPs loci and autism was analyzed through case-control association analysis and family-based transmission disequilibrium test.Results Fifty-two SNPs were involved for further analysis.1.Case-control association analysis showed that 6 SNPs (rs4658939,rs2793093,rs10495309,rs2492367,rs1 1122362,rs1073179) and 7 haplotypes (AGAAAG constructed with rs823163-rs823161-rs4658933-rs1417585-rs10864693-rs6541281,GGG and AAA constructed with rs4658939-rs2793093-rs10495309,GG and AG constructed with rs2492367-rs12046794,GAA constructed with rs9432040-rs2356606-rs1 1122362 and GG constructed with rs9431714-rs1073179) had significant differences between autistic patients and controls(x2 =4.704,4.915,5.568,8.087,4.043,5.183,5.369,5.295,4.440,5.304,7.615,4.018,4.811,P =0.030,0.027,0.018,0.005,0.044,0.023,0.021,0.021,0.035,0.021,0.006,0.045,0.028).2.In the transmission disequilibrium test analysis,2 SNPs (rs4658945,rs11122362) and 2 haplotypes (AG constructed with rs10495310-rs4658945,GAA constructed with rs9432040-rs2356606-rs11122362) showed significant transmission disequilibrium(x2=4.445,5.400,3.973,5.126,P =0.035,0.020,0.046,0.024).Conclusions The polymorphism of rs11122362 and GAA haplotype constructed with rs9432040-rs2356606-rs11122362 are associated with autism,and DISC1 gene is a susceptibility gene for autism in Chinese Han children.

Objective:To evaluate the analgesic effect and adverse reactions of butorphanol after stopping patient controlled intravenous analgesia (PCIA) pump in cesarean section.Methods:One hundred and twenty patients with cesarean section in Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from March 20, 2021 to December 8, 2021 were divided into three groups as follows: butorphanol group, diclofenac sodium suppository group and control group and there were 40 patients in each group. The vital signs, analgesic effect and adverse reactions among the three groups were compared. Meantime, the bladder and gastrointestinal function recovery and neonatal jaundice in three groups were also compared.Results:The visual analogue score (VAS) in butorphanol group was significantly lower than that of control group at 3 and 4 h after stopping PCIA pump: (2.16 ± 0.09) scores vs. (2.72 ± 0.25) scores, (2.21 ± 0.10) scores vs. (2.72 ± 0.21) scores, P< 0.05, but there was no significant difference in VAS at 6 and 12 h after stopping PCIA pump. VAS in diclofenac sodium suppository group was significantly lower than that of control group at 3 h after stopping PCIA pump: (2.06 ± 0.10) scores vs. (2.16 ± 0.09) scores, P<0.05, but there was no significant difference in VAS at 4, 6 and 12 h ( P>0.05). The 3 h VAS of butorphanol group was lower than that of diclofenac sodium suppository group, but the difference was not statistically significant ( P>0.05). The VAS of butorphanol group was lower than that of diclofenac sodium suppository group at 4 h after operation: (2.21 ± 0.10) scores vs. (2.56 ± 0.12) scores, and the difference was statistically significant ( P<0.05). The first time of getting out of bed and urination time in butorphanol group were later than diclofenac sodium suppository group and control group: (28.32 ± 1.36) h vs. (25.94 ± 0.92) h and (24.50 ± 0.64) h, (29.05 ± 1.67) h vs. (26.76 ± 1.05) h and (25.06 ± 0.65) h, and the difference was statistically significant ( P<0.05). While the anal exhaust time in diclofenac sodium suppository group was delayed, but the difference was not statistically significant ( P>0.05). Conclusions:The analgesic effect of butorphanol is better than diclofenac sodium suppository after stopping PCIA pump in cesarean section, but nursing care should be strengthened to urge patients to take early activities to reduce the occurrence of urinary retention.
