Objective:To investigate the factors affecting the prognosis of stage Ⅰa2-Ⅱa2 cervical cancer after laparoscopic radical hysterectomy (LRH), and to compare the prognosis and recurrence sites of patients with different colpotomy paths.Methods:The clinical data of 965 patients with stage Ⅰa2-Ⅱa2 cervical cancer who underwent LRH in the First Affiliated Hospital of Army Medical University from January 2015 to December 2018 were collected. The median age was 47.0 years of all patients with a median follow-up of 62 months (48-74 months). Cox regression was used to perform the univariate and multivariate analysis of the clinicopathological factors associated with the prognosis that included disease-free survival (DFS) and overall survival (OS). Patients were categorized into LRH through vaginal colpotomy (VC group, n=475) and LRH through intracorporeal colpotomy (IC group, n=490) according to the colpotomic approaches. The prognosis and recurrence sites of patients in each group were compared. Results:(1) During the follow-up period, 137 cases recurred (14.2%, 137/965) and 98 cases died (10.2%, 98/965). The 5-year DFS and OS were 85.8% and 89.9%, respectively. In univariate analysis, positive vaginal margin (PVM) was significantly affected the 5-year OS of patients with cervical cancer ( P=0.023), while clinical stage, maximum diameter of tumor, degree of pathological differentiation, lymph node metastasis (LNM), depth of cervical stromal invasion, parametrium involvement, and uterine corpus invasion (UCI) were significantly associated with 5-year DFS and OS in patients with cervical cancer (all P<0.05). In multivariate analysis, clinical stage ( HR=1.882, 95% CI: 1.305-2.716), LNM ( HR=2.178, 95% CI: 1.483-3.200) and UCI ( HR=3.650, 95% CI: 1.906-6.988) were independent risk factors of 5-year DFS (all P<0.001). Clinical stage ( HR=2.500, 95% CI: 1.580-3.956), LNM ( HR=2.053, 95% CI: 1.309-3.218), UCI ( HR=3.984, 95%C I: 1.917-8.280), PVM ( HR=3.235, 95% CI: 1.021-10.244) were independent risk factors of 5-year OS (all P<0.05). (2) Different colpotomy paths did not significantly affect the 5-year DFS and OS of patients with stage Ⅰa2-Ⅱa2 cervical cancer. The 5-year DFS in VC group and IC group were 85.9% and 85.6% ( P=0.794), and the 5-year OS were 90.8% and 89.3% ( P=0.966), respectively. Recurrence patterns consisted of intraperitoneal recurrence, pelvic recurrence, vaginal stump recurrence, and lymph node and distant metastasis. The intraperitoneal recurrence rate of VC group was significantly lower than that of IC group [0.6%(3/468) vs 2.3% (11/485), P=0.037], while the rates of pelvic recurrence, vaginal stump recurrence, lymph node and distant metastasis and overall recurrence were not significantly different between two groups (all P>0.05). Subgroup analysis of patients with different clinical stages, LNM and UCI showed that statistical differences of the intraperitoneal recurrence rates between two groups were only in patients without LNM (0.5% vs 2.3%, P=0.030) or without UCI (0.7% vs 2.3%, P=0.037). Conclusions:Clinical stage, LNM, PVM and UCI are independent risk factors for the prognosis of patients with stage Ⅰa2-Ⅱa2 cervical cancer. For patients without LNM or UCI, LRH through VC could reduce the intraperitoneal recurrence rate, while it is not enough to improve 5-year DFS and OS of patients. Low proportion of intraperitoneal recurrence, intra-operative tumor cells spillage to vagina stump and pelvic cavity might be the explanation.

This article reported the comprehensive management of an extremely preterm infant with severe bronchopulmonary dysplasia. The patient born at 26 +6 gestational weeks was transferred to Children's Hospital of Fudan University due to invasive mechanical ventilation dependence at 61 d after birth and was diagnosed with severe bronchopulmonary dysplasia. A comprehensive treatment plan was adopted, including appropriate fluid restriction, improving nutrition, glucocorticoid administration, using antibiotics against Ureaplasma urealyticum infection to reduce pulmonary parenchymal lesions and alleviating pulmonary hypertension. The preterm infant was successfully extubated to non-invasive ventilation and subsequently weaned to a high-flow nasal cannula. Then, the patient was discharged at 372 d after birth (correct gestational age nine months and six days). At the 3-month follow-up after discharge, the patient remained on high-flow oxygen, but with lower flow and concentration of oxygen. Moreover, the growth, development and lung images were significantly improved. Follow-up to correct gestational age one year and 11 months, the child was not on oxygen any more, but on rehabilitation due to language and motor development retardation.

Objective To analyze the correlation of interferon-induced protein with tetratricopeptide repeats 1(IFIT1)with immune infiltration and prognosis of ovarian cancer(OC).Methods GEO database was employed to select the tumor immune related genes,and Kaplan-Meier and Prognoscan databases were used to identify the genes significantly associated with OC prognosis.The differential expression of IFIT1 between OC tissue and normal tissue were confirmed with GEPIA,Human Protein Atlas,and Timer databases.The expression level of IFIT1 in OC tissues with different grades and stages were analyzed in the UALCAN database.In addition,based on David database,GO enrichment analysis was used to analyze the interacting genes and proteins of IFIT1 in the String and Genemania databases.Timer and Tisidb databases verified the correlation between IFIT1 and immune cells mutually.Finally,after IFIT1 knockdown xenograft model was constructed based on lentiviral vector of IFIT1 shRNA,the tumor growth was observed in the transplanted nude mice,and infiltration of neutrophils was observed with immunohistochemical assay.Results FIT1,a tumor immune gene,selected from the GEO database,Kaplan-Meier and Prognoscan databases,was negatively correlated with the OC prognosis.GEPIA,Human Protein Atlas,Timer database,and UALCAN database indicated that the expression level of IFIT1 was significantly higher in the OC tissues than the normal ovarian tissues,and had no obvious correlation with tumor stage and grade.Analysis in String,Genemania,and David database found the interaction genes and proteins of IFIT1 were enriched in activation of 2'-5'oligonucleotide synthase,virus defense,and innate immunity,and other processes.The Timer database presented that IFIT1 was positively correlated with the infiltration of CD8+T cells,B cells,dendritic cells,neutrophils,and macrophage in OC,with neutrophils having the most significant correlation.Tisidb and GSCA also confirmed the positive correlation between IFIT1 and neutrophil infiltration in OC(P<0.05).RT-qPCR and Western blotting confirmed that IFIT1 knockdown resulted in suppressed tumor growth in OC cells xenograft nude mice(P<0.05)and reduced neutrophil infiltration in the xenograft tissues.Conclusion IFIT1 may influence the malignant progression of OC by promoting neutrophil infiltration.
