Effect of rs1344706 in the ZNF804A gene on the brain network.
ZNF804A rs1344706 (A/C) was the first SNP that reached genome-wide significance for schizophrenia. Recent studies have linked rs1344706 to functional connectivity among specific brain regions. However, no study thus far has examined the role of this SNP in the entire functional connectome. In this study, we used degree centrality to test the role of rs1344706 in the whole-brain voxel-wise functional connectome during the resting state. 52 schizophrenia patients and 128 healthy controls were included in the final analysis. In our whole-brain analysis, we found a significant interaction effect of genotype × diagnosis at the precuneus (PCU) (cluster size = 52 voxels, peak voxel MNI coordinates: x = 9, y = - 69, z = 63, F = 32.57, FWE corrected P < 0.001). When we subdivided the degree centrality network according to anatomical distance, the whole-brain analysis also found a significant interaction effect of genotype × diagnosis at the PCU with the same peak in the short-range degree centrality network (cluster size = 72 voxels, F = 37.29, FWE corrected P < 0.001). No significant result was found in the long-range degree centrality network. Our results elucidated the contribution of rs1344706 to functional connectivity within the brain network, and may have important implications for our understanding of this risk gene's role in functional dysconnectivity in schizophrenia
Clinical Study Efficacy of Combined Laparoscopic and Hysteroscopic Repair of Post-Cesarean Section Uterine Diverticulum: A Retrospective Analysis
Background. Diverticulum, one of the long-term sequelae of cesarean section, can cause abnormal uterine bleeding and increase the risk of uterine scar rupture. In this study, we aimed to evaluate the efficacy of combined laparoscopic and hysteroscopic repair, a newly occurring method, treating post-cesarean section uterine scar diverticulum. Methods. Data relating to 40 patients with post-cesarean section uterine diverticulum who underwent combined laparoscopic and hysteroscopic repair were retrospectively analyzed. Preoperative clinical manifestations, size of uterine defects, thickness of the lower uterine segment (LUS), and duration of menstruation were compared with follow-up findings at 1, 3, and 6 months after surgery. Results. The average preoperative length and width of uterine diverticula and thickness of the lower uterine segment were recorded and analyzed. The average durations of menstruations at 1, 3, and 6 months after surgery were significantly shorter than the preoperative one ( < 0.05), respectively. At 6 months after surgery, the overall success improvement rate of surgery was 90% (36/40). Three patients (3/40 = 7.5%) developed partial improvement, and 1/40 (2.5%) was lost to follow-up. Conclusions. Our findings showed that combined treatment with laparoscopy and hysteroscopy was an effective method for the repair of post-cesarean section uterine diverticulum
Polymorphism in schizophrenia risk gene MIR137 is associated with the posterior cingulate Cortex's activation and functional and structural connectivity in healthy controls
MIR137 gene has been repeatedly reported as a schizophrenia risk gene in genome-wide association studies (GWAS). A polymorphism (rs1625579) at the MIR137 gene has been associated with both neural activation and behavioral performance during a working memory task. This study examined MIR137's associations with task-related (N-back working memory) fMRI, resting state fMRI, and diffusion tensor images (DTI) data in 177 healthy adults. We found less deactivation of the PCC in risk allele homozygotes (TT) as compared to the GT heterozygotes (cluster size = 630 voxels, cluster level PFWE < 0.001) during the N-back task, which replicated previous findings. Using the identified cluster within the PCC as the seed, we further found decreased functional connectivity between the PCC and the anterior cingulate cortex and its adjacent medial prefrontal cortex (ACC/MPFC) in risk allele homozygotes during both resting state (cluster size = 427 voxels, cluster level PFWE = 0.001) and the N-back task (cluster size = 73 voxels, cluster level PFWE = 0.05). Finally, an analysis of our DTI data showed decreased white matter integrity of the posterior cingulum in risk allele homozygotes (cluster size = 214 voxels, cluster level PFWE = 0.03). Taken together, rs1625579 seems to play an important role in both functional and structural connectivity between the PCC and the ACC/MPFC, which may serve as the brain mechanisms for the link between rs1625579 and schizophrenia
Risk variants in the S100B gene, associated with elevated S100B levels, are also associated with visuospatial disability of schizophrenia
Rs9722 and rs1051169 have been reported as affecting the levels of S100B in the serum or the brain, and haplotypes containing these two SNPs have been associated with schizophrenia. The current study investigated the role of the S100B gene in an endophenotype of schizophrenia-spatial disability. 304 schizophrenia patients and 196 healthy controls were given a block design task and a mental rotation task. Results showed that the two aforementioned SNPs and related haplotypes were associated with the spatial disability of schizophrenia patients. Specifically, risk factors for the elevated S100B levels, including the A allele of rs9722, the G allele of rs1051169, and the AG haplotype, were associated with a poorer performance on both tests of spatial ability, especially the mental rotation task. These results implicate a role for S100B gene polymorphisms in the cognitive functions of schizophrenia patients and encourage further investigation into spatial disability as an endophenotype of schizophrenia

Effects of Different Intervention Measures for Breech Presentation/Transverse Lie Position on Maternal and Neonatal Outcomes: a Network Meta-analysis
Background Untimely and ineffectively treated breech or transverse lie position of a fetus may increase the rate of cesarean section, and the risk of uterine rupture and other serious childbirth complications, endangering the lives of mothers and newborns. However, at present, there is no conclusion on the effectiveness and selection priority of different interventions for it during childbirth. Objective To perform a network meta-analysis of the impact of different interventions for breech or transverse lie position on maternal and neonatal outcomes. Methods We searched the Cochrane Library, PubMed, Web of Science, Embase, CINAHL, CBM, CNKI, VIP, and Wanfang Data Knowledge Service Platform for randomized controlled trials (RCTs) of the effects of different interventions for breech or transverse lie position on maternal and neonatal outcomes from inception to March 2022. Two researchers independently completed literature screening and data extraction, and quality assessment. R 4.1.1 and Stata 16.0 were used for data analysis and graph drawing. Consistency test and convergence analysis of the studies were performed. SUCRA was used to rank the effectiveness of each intervention and determine the most effective one. Results A total of 36 RCTs were included, including 7 419 parturients. The interventions involved were: knee-chest position, moxibustion/stimulation of Zhiyin acupoint, and external cephalic version (ECV) under different types of uterine contraction inhibitors/anesthesia. Network meta-analysis showed that compared with moxibustion/stimulation to Zhiyin acupoint, the success rate of moving a breech or transverse lie position to a head position was lower by usual nursing〔RR=0.54, 95%CI (0.32, 0.86) , P<0.05〕. The success rate of moving a breech or transverse lie position to a head position without uterine contraction inhibitor before ECV was lower than that using β2-adrenergic receptor agonists〔RR=0.60, 95%CI (0.38, 0.62) , P<0.05〕. The vaginal delivery rate with calcium channel blockers but without uterine contraction inhibitors was lower than that using β2-adrenergic receptor agonists〔RR=0.60, 95%CI (0.39, 0.89) , P<0.05; RR=0.60, 95%CI (0.39, 0.95) , P<0.05〕. The success rate of moving a breech or transverse lie position to a head position by ECV without anesthesia was lower than that using intravenous anesthesia〔RR=0.71, 95%CI (0.53, 0.96) , P<0.05〕 or intraspinal anesthesia〔RR=0.65, 95%CI (0.49, 0.85) , P<0.05〕. Compared with non-anesthesia, the use of intravenous anesthesia and intraspinal anesthesia during ECV could reduce the post-ECV pain score〔WMD=-1.97, 95%CI (-2.49, -1.46) , P<0.05; WMD=-3.80, 95%CI (-5.10, -2.50) , P<0.05〕. The three top interventions for terms of effectiveness ranked by SUCRA were: moxibustion/stimulation to Zhiyin acupoint, the use of β2-adrenergic receptor agonists to suppress uterine contractions before ECV, and the use of spinal anesthesia during ECV. Conclusion Based on the results of network meta-analysis and SUCRA ranking, moxibustion/stimulation to Zhiyin acupoint, the use of β2-adrenergic receptor agonists to inhibit uterine contractions before ECV, and the implementation of ECV under spinal anesthesia for moving a breech or transverse lie position to a head position during late pregnancy have a good effect on improving the maternal and neonatal outcomes, but this conclusion still needs to be further verified by more high-quality, large-sample studies
