Intraoperative aortic balloon occlusion is a relatively safe method for treating placenta previa and/or placenta accreta during scheduled and emergency CS and might be helpful to prevent hysterectomy and embolization in women wishing to preserve fertility.

This study aimed at investigating the biological functions of long non-coding RNAs (lncRNAs) hox transcript antisense intergenic RNA (HOTAIR) in resistant ovarian cancer cells, exploring the regulation effect of HOTAIR on HOXA7, and investigating their influence on the chemosensitivity of ovarian cancer cells. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied for the verification of HOTAIR expression in resistant and sensitive groups. How HOTAIR downregulation affected cell proliferation, migration and invasion, and apoptosis were determined using the MTT assay and the colony formation assay, the Transwell assay and flow cytometry analysis, respectively. Immunohistochemistry was used to inspect the protein expression of HOXA7 in resistant and sensitive ovarian cancer tissues. The regulation relationship between HOTAIR and HOXA7 was investigated by qRT-PCR and Western blot. The effect of HOTAIR and HOXA7 on tumor growth was confirmed by the tumor xenograft model of nude mice. By knocking down HOXA7, HOTAIR downregulation restrained the ovarian cancer deterioration in functional experiments. Silencing of HOTAIR and HOXA7 could effectively inhibit tumor growth and increase chemosensitivity of ovarian tumors in nude mice. Downregulation of HOTAIR negatively affected the survival and activity of resistant ovarian cancer cells, and suppressed the expression of HOXA7. Silencing of HOTAIR and HOXA7 could increase the chemosensitivity of ovarian cancer cells, thus suppressing tumor development.

We reported a rare case of acute disseminated intravascular coagulation (DIC) after dilation and curettage in an adenomyosis and missed abortion patient. The clinical performance improved after treatment with tranexamic acid, blood transfusions and subtotal hysterectomy. Hemorrhage, degeneration and necrosis were found in the myometrium. Pregnancy-related thrombotic tendency, accelerated uterus tissue injury after curettage, activation of coagulation system, microthrombosis formation, myometrium necrosis, exhaustion of coagulation factors and hyperfibrinolysis might play the crucial roles in the pathophysiology of acute DIC. Physicians should be alert that adenomyosis patients undergoing dilation and curettage may be in danger of DIC.
