The Janus kinase/signal transducers and activators of transcription (JAK-STAT) control natural killer (NK) cells development and cytotoxic functions, however, whether long non-coding RNAs (lncRNAs) are involved in this pathway remains unknown. We found that miR155HG was elevated in activated NK cells and promoted their proliferation and effector functions in both NK92 and induced-pluripotent stem cells (iPSCs)-derived NK (iPSC-NK) cells, without reliance on its derived miR-155 and micropeptide P155. Mechanistically, miR155HG bound to miR-6756 and relieved its repression of JAK3 expression, thereby promoting the JAK-STAT pathway and enhancing NK cell proliferation and function. Further investigations disclosed that upon cytokine stimulation, STAT3 directly interacts with miR155HG promoter and induces miR155HG transcription. Collectively, we identify a miR155HG-mediated positive feedback loop of the JAK-STAT signaling. Our study will also provide a power target regarding miR155HG for improving NK cell generation and effector function in the field of NK cell adoptive transfer therapy against cancer, especially iPSC-derived NK cells.

Objective:To determine the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema using Mendelian randomization (MR) analyses.Methods:This study was a secondary data analysis based on the summary data of genome-wide association studies (GWAS), which involved 293 723 participants (educational attainment) from the Social Science Genetics Association Consortium and 462 013 participants [allergic rhinitis and (or) eczema] from the UK Biobank. Genetic variants that were closely related to educational attainment were identified as instrumental variables. Two-sample MR analyses, including inverse-variance weighted (IVW), MR-Egger regression, weighted median method and weighted model-based estimation, were performed to investigate the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, in which the odds ratio ( OR) values were used as indicators. Results:A total of 70 single-nucleotide polymorphisms (SNPs) were chosen as instrumental variables. The MR-Egger regression results suggested that the genetic pleiotropy was unlikely to bias our results ( P=0.107). In the univariable MR analyses, IVW regression showed that the risk of allergic rhinitis and (or) eczema was OR=1.044 (95% CI: 1.020-1.069, P<0.001) and OR=1.170 (95% CI: 1.074-1.256, P<0.001), respectively, for the increase in the duration of education by one year or one standard deviation ( SD) (3.71 years). In the reverse MR analysis, IVW regression showed little evidence that allergic rhinitis and (or) eczema affected educational attainment ( OR=1.020, 95% CI: 0.927-1.023, P=0.683). The results of the weighted median method and weighted mode-based estimation were consistent with the results of IVW. Conclusion:This study suggests that there is a positive causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, which means that educational attainment can increase the occurrence of allergic rhinitis and (or) eczema.

Objective:To evaluate the application value of preconceptional laparoscopic cervical cerclage(LCC)in improving the pregnancy outcomes with cervical incompetence(CIC).Methods:Clinical data of 112 pa-tients with CIC who underwent preconceptional LCC in The First Affiliated Hospital of Zhengzhou University from July 1,2014 to May 31,2023 were retrospectively reviewed.The surgical indications of preconceptional LCC in-cluded:failed transvaginal cervical cerclage(TCC)(42 patients),history of cervical surgery+failed TCC(7 pa-tients),unsuitability for TCC(10 patients)and strong request from patients(53 patients).The surgical situation and pregnancy outcome of preconceptional LCC were analyzed,and the gestational age of delivery before and af-ter preconceptional LCC surgery and different surgical indications were compared in postoperative delivery pa-tients who underwent preconceptional LCC.Results:The median operation time of 112 patients was 65.5 min,the median intraoperative blood loss was 10.0 ml,and there were no intraoperative complications.The postopera-tive hospital stay was 2.9±0.6 d.108 cases were followed up after surgery,with 77 cases of pregnancy and de-livery after LCC.A total of 205 deliveries were made before surgery,and 81 deliveries were made after surgery.Successful postoperative deliveries(delivery after 28 weeks)were 78(96.3% ),with an average gestational age 37.4±1.7 weeks.The preterm birth rate was 16.7%,term birth rate was 83.3% .The delivery rate at≥28 weeks after preconceptional LCC was significantly higher than the previous delivery rate of pre pregnancy LCC(96.3% vs.10.7%,P<0.05),and the gestational age was significantly prolonged(36.4±5.5 weeks vs.19.8±7.5 weeks,P<0.05).The postoperative delivery gestational week of preconceptional LCC with different surgical indi-cations was significantly later than the previous delivery gestational week of pre pregnancy LCC(P<0.05),ex-cept for the indication of unsuitability for TCC(P>0.05).Conclusions:Preconceptional LCC surgery is highly safe and can effectively prolong the gestational age and improve pregnancy outcomes in patients with CIC.It can be an effective treatment method for patients with a history of TCC failure.
