“…Fisher found that in women who developed hypertensive disorders of pregnancy in the second trimester, serum inhibin A levels were not different from those of normal pregnant women [ 7 ]. Yi et al suggested that the serum inhibin A concentration of pregnant women in the second trimester was not associated with the occurrence of preeclampsia [ 8 ]. Kumar et al showed that activin A can be used as an independent risk factor for predicting early-onset preeclampsia, and it is associated with cell-free fetal DNA, both of which are higher in the serum of pregnant women with preeclampsia [ 9 ].…”

In order to explore the changes and clinical significance of serum TNF-α and IL-6 and ET levels in the pathogenesis of hypertensive disorders of pregnancy (HDIP), echocardiography, and serum IL-6 and TNF-α changes in pregnant women with a hypertensive disorder, a clinical analysis method was proposed. A retrospective analysis of 59 pregnant women who visited the obstetrics department of a provincial hospital was divided into 2 groups. The normal control group consisted of 32 normal, uncomplicated pregnant women; the preeclampsia group included 27 patients with systolic blood pressure > 140 mmHg and/or diastolic blood pressure > 90 mmHg who developed proteinuria after 20 weeks of gestation. The levels of TNF-α and IL-6 in serum of normal pregnant women and pregnant women with preeclampsia were detected by enzyme-linked immunosorbent assay (ELISA). The results showed that compared with normal pregnant women, the serum levels of TNF-α and IL-6 in the early pregnant women of Zizhi were significantly increased, and the trend of increased TNF-α and IL-6 levels was related to the severity of complications. With the mean pulmonary artery pressure > 50 mmHg , the serum TNF-α level of pregnant women was significantly higher than that of pregnant women with mean pulmonary artery pressure < 50 mmHg . The analysis found that the serum levels of TNF-α and IL-6 in patients with hypoxic gestational hypertension were significantly increased, and the results of lung tissue immunohistochemistry also showed that serum TNF-α and IL-6 levels in patients with hypoxic gestational hypertension were significantly increased. And serum TNF-α and IL-6 levels were positively correlated with right ventricular systolic blood pressure (RVSP). Conclusion. This study revealed that the elevated levels of serum TNF-α and IL-6 are closely related to the pathophysiological process of gestational hypertension. Serum levels of TNF-α and IL-6 and ET were significantly increased, and the changes of serum TNF-α and IL-6 and ET levels had important clinical value for closely monitoring the severity of the disease and the development of the disease.

“…The TBADC is a flash architecture, which makes the operation speed rapidly decrease as the resolution increases [11,12,13]. To overcome this problem, a hybrid voltage-time two-step analog-to-digital converter (ADC) is proposed [14].…”

This letter proposed a coarse-fine two stages time-based analogto-digital converter (TBADC). The coarse 4-bit TBADC is pipelined with the fine 5-bit TBADC for high conversion rate. There is one bit redundancy to tolerate the gain and offset mismatch between the coarse and fine stages. The residue is transferred by splitting the capacitor array in a fully passive way, which is non-attenuated and consumes less power. The dynamic VTC in this design has a high linearity over a wide input range. The proposed ADC is designed in a 65-nm CMOS technology. It consumed 3.1 mW at 1 GHz and had a Walden figure of merit of 15.9 fJ/conversion step.
