Objective To observe the value of changes of neutrophil-to-lymphocyte ratio(NLR)before and after the first interventional treatment of hepatocellular carcinoma(HCC)for predicting patient's overall survival(OS).Methods Totally 92 HCC patients who underwent the first time TACE or TACE+hepatic artery infusion chemotherapy(HAIC)were retrospectively enrolled.The patients were divided into NLR ratio(NLRR)＜1.29 group(n=54)and≥1.29 group(n=38)based on the ratio of NLR after to before treatment,also ΔNLR＜0.87 group(n=60)and≥0.87 group(n=32)based on the difference of NLR after and before treatment.Clinical data were compared between groups,survival analysis was performed,and the value of NLRR and ΔNLR for predicting OS were analyzed.Results No significant difference of clinical data was found between NLRR＜1.29 and≥1.29 groups,nor between ΔNLR＜0.87 and≥0.87 groups(all P＞0.05).The median OS of 92 patients was 30.90 months,which in NLRR＜1.29 group(55.10 months)was longer than that in NLRR≥1.29 group(22.30 months,P=0.005),while in ΔNLR＜0.87 group(55.10 months)was longer than that in ΔNLR≥0.87 group(14.20 months,P=0.003).Cox regression analysis showed that the maximum diameter of tumor≥5 cm,distant metastasis,ascites,NLRR≥1.29 and ΔNLR≥0.87 were all independent risk factors of OS(all P＜0.05).Taken 1.29 and 0.87 as the best cut-off value,respectively,the area under the curve of NLRR and ΔNLR for predicting OS was 0.620 and 0.610,respectively.Conclusion NLRR and ΔNLR were helpful for predicting OS of HCC patient after the first interventional treatment.

Objective:To explore the differences of the circadian rhythm gene polymorphisms between patients with major depressive disorder and those with bipolar disorder, providing a genetic basis for differential diagnosis.Methods:70 patients who were still diagnosed with major depressive disorder after 5 years and 68 patients who were still diagnosed with bipolar disorder from Zhongda Hospital affiliated to Southeast University from 2012 to 2018 were included in this study. Single nucleotide polymorphisms (SNPs) of circadian rhythm gene were selected for genetic testing. And the differences in genotype frequency, allele frequency, and haplotypes of each SNP between major depressive disorder and bipolar disorder were analyzed using UNPHASED 3.1.7.Results:The analysis of genotype frequency revealed statistically significant differences in genotype frequency of PER1rs2253820, PER1rs2735611, PER3rs12566042, PER3rs17031614, and PER3rs79372391 between the two groups ( OR(95% CI)=2.386(1.173-4.854), 2.357(1.166-4.764), 0.351(0.176-0.703), 0.389(0.196-0.773), 0.389(0.196-0.773) respectively; all P<0.05). Haplotype analysis showed that the T-C-C-T-G haplotype, in CLOCK loci (rs12505266, rs2272073, rs3817444, rs11133389 and rs12505265) was significantly different between major depressive disorder group and bipolar disorder group ( OR(95% CI)=0.108(0.010-1.185), P=0.027). Conclusion:There are significant differences in circadian rhythm gene polymorphisms between patients with major depressive disorder and bipolar disorder. Carrying the PER1rs2253820TT and PER1rs2735611GG genotypes is a risk factors for bipolar disorder.

Objective:To compare the incidence of postoperative complications of single- and multiple-perforator flaps, to provide reference for future clinical decision.Methods:Literatures on the comparison of postoperative complications of single- and multiple-perforator flaps at home and abroad from January 1995 to December 2020 were searched in PubMed, Cochrane Library, Embase, Wanfang, CNKI, VIP database. The literatures were screened and extracted according to the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.3 software.Results:8 studies were included, including 1 008 flaps. There were 535(53%) single-perforator flaps, 473(47%) multiple-perforator flaps. Compared with multiple-perforator flaps, single-perforator flaps had a higher rate of venous crisis ( OR=2.29, 95% CI: 1.25-4.21, Z=2.67, P=0.008) and a higher rate of fat necrosis ( OR=2.04, 95% CI: 1.02-4.10, Z=2.10, P=0.040), the total necrosis rate of flaps was higher ( OR=2.71, 95% CI: 1.26-5.86, Z=2.54, P=0.010), and the differences were statistically significant. There were no significant differences in the incidence of arterial crisis ( OR=1.18, 95% CI: 0.48-2.90, Z=0.37, P=0.710) and partial necrosis of flaps ( OR=1.20, 95% CI: 0.61-2.36, Z=0.52, P=0.600). Conclusion:Compared with multiple-perforator flap, single-perforator flap may have higher incidence of venous crisis, fat necrosis and complete necrosis.
