Abstract
OBJECTIVE To investigate the clinical effect of continuous subcutaneous injection of insulin analogues in pregnant women with diabetes mellitus complicated with ketoacidosis. METHODS A total of 92 pregnant patients with diabetes mellitus complicated with ketoacidosis from June 2014 to January 2021 were selected. All patients were randomly divided into an observation group and control group according to the method of random number. The control group received intravenous infusion of insulin, and the observation group received continuous subcutaneous infusion of quick-acting insulin analogues. The clinical effects of the two groups were observed. RESULTS The time needed to control blood glucose <13.8 mmol/L, the amount of insulin needed to control blood glucose <13.8 mmol/L, the time needed to correct DKA, and the amount of insulin needed to correct DKA in the observation group were significantly less than those in the control group (P < 0.05). Compared with the control group, the average occurrence times of hypoglycemia, the length of stay, the total amount of insulin in hospital, and the total amount of insulin used during pregnancy in the observation group were significantly less than those in the control group (P < 0.05). The values of SCr, CRP, BUN, arterial blood gas pH, and adiponectin in the two groups were significantly improved as compared with those before treatment, and the improvement in the observation group was significantly better than that in the control group (P < 0.05). After treatment, the fasting blood glucose, 2-hour postprandial blood glucose, carbon dioxide binding capacity, and glycosylated hemoglobin in the experimental group were significantly better than those in the routine group, and the difference was statistically significant (P < 0.05). CONCLUSION Continuous subcutaneous injection of insulin analogues is effective in the treatment of diabetic patients with ketoacidosis, which can effectively improve blood glucose, carbon dioxide binding capacity, and glycosylated hemoglobin and accelerate the negative conversion of urinary ketone body. It is worth popularizing to reduce the occurrence of hypoglycemia and the dose of insulin and shorten the time of hospitalization.

Abstract
Transforming growth factor-β1 (TGF-β1) plays a vital role in the process of epithelial-to-mesenchymal transition (EMT) in breast cancer and the cullin 4A (CUL4A) gene is overexpressed in primary breast cancer. However, whether TGF-β1 signaling can induce CUL4A expression has not been investigated to date, at least to the best of our knowledge. In this study, using breast cancer cell lines, we found that the CUL4A expression level was increased following EMT induced by TGF-β1. Silencing CUL4A expression or CUL4A inhibition by thalidomide suppressed the EMT process induced by TGF-β1. We also found that CUL4A was associated with the expression of zinc finger E-box-binding homeobox 1 (ZEB1) which was induced by TGF-β1. These results suggest that CUL4A is upregulated in TGF-β1-induced EMT, and has a regulatory function in this process. The identification of CUL4A as a downstream target of TGF-β1 represents a critical pro-survival mechanism in breast cancer progression and provides another point for therapeutic intervention in breast cancer.
