High proportion of CD4(+) CD25(+) Treg and CD4(+)CD25(+)CD127(-) Treg is closely related to the high level of E2 during pregnancy. It suggested that high level of estrogen may induce an increase of CD4(+) CD25(+) Treg in peripheral blood, and then influence the immune function of pregnant women. The results of this experiment might play an important role of estrogen in immune-modulation during pregnancy.

Objectives LncRNA nuclear‐enriched abundant transcript 1 (NEAT1) participates in the development and progression of multiple malignancies. However, the molecular mechanism by which NEAT1 contributes to colorectal cancer (CRC) remains unclear. Methods The association between lncRNA NEAT1 expression and clinicopathological characteristics and prognosis in patients with CRC was analysed by TCGA RNA‐sequencing data. MTT, colony formation, flow cytometry, transwell assays and a xenograft tumour model were used to assess the functions of NEAT1. Bioinformatics and spearman correlation analysis were used to identify the NEAT1‐specific binding with miRNAs, and luciferase gene report and RIP assays were performed to confirm the interaction between miR‐193a‐3p (miR‐193a) and NEAT1 in CRC cells. Results Upregulation of NEAT1 expression was significantly correlated with TNM stage, poor survival and tumour recurrence in patients with CRC, and acted as an independent prognostic factor for tumour recurrence. Knockdown of NEAT1 suppressed cell proliferation, colony formation abilities and invasive potential and induced cell apoptosis, but overexpression of NEAT1 reversed these effects. Furthermore, NEAT1 was confirmed to act as a sponge of miR‐193a, and knockdown of NEAT1 attenuated miR‐193a inhibitor‐induced tumour promoting effects and L17RD expression in CRC cells. miR‐193a harboured negative correlation with NEAT1 and IL17RD expression in CRC specimens. In vivo experiment further validated the inhibitory effects of NEAT1 knockdown on xenograft tumour growth. Conclusion Our findings demonstrate that lncRNA NEAT1 acts as an oncogenic role in CRC cells by sponging miR‐193a and may represent a potential marker for CRC patients.

Study Objective: To compare the surgical and oncologic outcomes between open abdomen radical hysterectomy (ARH) and laparoscopic radical hysterectomy (LRH) for cervical cancer.Methods: Retrospective observational study with propensity score matching was used to ensure balanced groups for ARH and LRH. One-hundred-and-ninety-eight women with cervical cancer, 99 treated using ARH and 99 using LRH, between January 2012 and December 2014. Outcomes included disease-free survival (DFS), overall survival (OS), intra-operative factors, post-operator recovery, urinary retention, and adverse events. Moreover, the inverse probability of the treatment weighting (IPTW) method was also used.Main Results: Compared with ARH, LRH was associated with a lower volume of blood loss (P < 0.001) and transfusion rate (P < 0.001), with a broader resection of the parametrium (P < 0.001). Post-operatively, the time to first flatus was shorter for LRH than ARH (P < 0.001) but the rate of urinary retention was higher for LRH (22.2%) than ARH (8.1%; P = 0.009). DFS and OS were similar between groups. By IPTW, laparoscopy was also not associated with poorer survival in terms of DFS (HR 1.52, CI 0.799–2.891, P = 0.202) or OS (HR 0.942, HR 0.425–2.09, P = 0.883).Conclusion: Compared with ARH, LRH provided better intra-operative and post-operative outcomes, with no significant difference in oncologic outcomes and survival. Urinary retention remains a clinical issue to improve with LRH. The technology of LRH has been improved in China to address the inconsistent results of oncologic outcomes in previous studies. Whether these improvements could be effective needs to be investigated in the future.

In spite of being a promising therapeutic modality, gene therapy has limited clinical applications, mostly due to the lack of spatiotemporal resolution and inadequate efficacy. Herein, we present a facile strategy to remotely control intracellular gene expression by using gold nanorods (Au NRs) derived, host-guest interactions mediated supramolecular vesicles as a gene carrier and photothermal transducer. Upon pulsed laser irradiation, mild photothermal conditions dissociate supramolecular vesicles to release gene and simultaneously activate heat shock protein-70 promoter (Hsp70) for spatiotemporally initiating gene expression inside cancer cells.Subsequently, upon introducing a polymeric guest species specifically into cancer cells, the dissociated Au NRs functionalized with macrocyclic host molecules could re-aggregate rapidly in cells to retard exocytosis of these NRs, thereby allowing deferred photothermal therapy to enhance the overall therapeutic outcome.

We propose a contemporary treatment strategy in line with current practice. First, all suspected cases of vaginal YST should be diagnosed by histopathological examination and serum AFP levels. Second, nonsurgical treatment with PEB chemotherapy should be initiated until patients achieve bCR, followed by an additional 2 cycles of consolidation therapy to optimize results and reduce the risk of remission.
