Objective: To explore the effect of different midwifery methods on the pelvic floor function of parturients and nursing experience. Methods: From January 2018 to December 2018, 200 cases of vaginal delivery in Enze Obstetrics and Gynecology Hospital of Taizhou Hospital were selected as study objects.According to the random number table method, they were divided into non-invasive midwifery group and traditional midwifery group, with 100 cases in each group.The non-invasive midwifery group adopted non-invasive midwifery, while the traditional midwifery group adopted traditional midwifery.The pelvic floor muscle strength, pelvic floor muscle dysfunction and postpartum hemorrhage were observed in the two groups. Results: There was no statistically significant difference in pelvic floor muscle strength between the two groups in grade 0, grade Ⅰ, grade Ⅱ, grade Ⅲ and grade Ⅳ(all P>0.05). The pelvic floor muscle strength of the observation group in grade Ⅴ (45.00%) was higher than that of the control group (31.00%), the difference was statistically significant (χ²=4.160, P<0.05). The incidence of sexual dysfunction (15.00%) and stress urinary incontinence (28.00%) in the observation group were significantly lower than those in the control group (41.00%, 54.00%) (χ²=16.766, 13.973, all P<0.05). The amount of bleeding 2 hours after delivery in the observation group [(245.93±19.89)mL] was less than that in the control group [(297.42±24.21)mL] (t=16.433, P<0.05). Conclusion Non-invasive midwifery has little effect on the pelvic floor function of parturients, and the incidence rate of sexual dysfunction and stress urinary incontinence is low, and the amount of bleeding is small, which is worthy of clinical reference.

ObjectiveTo screen key genes associated with neuroblastoma （NB） diagnosis and prognosis using the Gene Expression Omnibus （GEO） database， and to investigate the expression and clinical significance of nucleoporin 93 （NUP93） in NB tissues. MethodsNB gene chip data （GSE73517， GSE49710， GSE19274） were retrieved from the GEO database. Differentially expressed genes （DEGs） commonly upregulated in high-risk groups were screened. The R2 database was then used to assess the prognostic value of DEGs that were commonly upregulated in the MYCN amplification group. Finally， NUP93 expression levels in the tissues from 60 NB， 25 ganglioneuroblastoma （GNB）， and 26 ganglioneuroma （GN） cases were measured by immunohistochemistry . ResultsTwenty-five DEGs were identified as commonly upregulated in high-risk groups. Among these， 10 genes （SIVA1， NUP93， STIP1， LSM4， RAI14， MYOZ3， KNTC1， TNFRSF10B， TACC3 and CEP152） showed significantly higher expression in MYCN-amplified subgroups （P＜0.05）. Survival analysis revealed that high NUP93 expression was associated with shorter overall survival （HR = 4.0， 95% CI： 3.0，5.3， P = 1.80 × 10⁻³⁴）. Immunohistochemistry results revealed that NUP93 expression in NB tissues was significantly higher than in GNB and GN tissues （P＜0.001）. NUP93 expression was positively correlated with high mitosis-karyorrhexis index （MKI； P=0.040）， poor differentiation （P＜0.001）， and MYCN expression （r_s = 0.793， P ＜0.001）. ConclusionsHigh expression of NUP93 is associated with high MKI and poor differentiation， and predicts unfavorable prognosis in patients with NB， suggesting it may promote tumor progression by regulating MYCN. NUP93 has the potential to be a novel diagnostic biomarker and therapeutic target for NB.
