ABSTRACT

Objective: To explore the influencing factors of pregnancy-induced hypertensive disorders in pregnancy (HDP) with organ or system impairment in pregnant women, and to analyze and compare the differences of HDP subtypes in different regions of China. Methods: A total of 27 680 pregnant women with HDP with complete data from 161 hospitals in 24 provinces, autonomous regions and municipalities were retrospectively collected from January 1, 2018 to December 31, 2018. According to their clinical manifestations, they were divided into hypertension group [a total of 10 308 cases, including 8 250 cases of gestational hypertension (GH), 2 058 cases of chronic hypertension during pregnancy] and hypertension with organ or system impairment group [17 372 cases, including 14 590 cases of pre-eclampsia (PE), 137 cases of eclampsia, 2 645 cases of chronic hypertension with PE]. The subtype distribution of HDP in East China (6 136 cases), North China (4 821 cases), Central China (3 502 cases), South China (8 371 cases), Northeast China (1 456 cases), Southwest China (2 158 cases) and Northwest China (1 236 cases) were analyzed. By comparing the differences of HDP subtypes and related risk factors in different regions, regional analysis of the risk factors of HDP pregnant women with organ or system impairment was conducted. Results: (1) The proportions of HDP pregnant women with organ or system impairment in Northeast China (79.05%, 1 151/1 456), Central China (68.42%, 2 396/3 502) and Northwest China (69.34%, 857/1 236) were higher than the national average (62.76%, 17 372/27 680); the proportions in North China (59.18%, 2 853/4 821), East China (60.85%, 3 734/6 136) and South China (59.56%, 4 986/8 371) were lower than the national average, and the differences were statistically significant (all P<0.05). (2) Univariate analysis showed that the proportions of primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history in the hypertension with organ or system impairment group were higher than those in the hypertension group, and the differences were statistically significant (all P<0.05). Multivariate logistic regression analysis showed that primiparas, non-Han, non-urban household registration, irregular prenatal examination and PE history were independent risk factors for HDP pregnant women with organ or system impairment (all P<0.05). (3) Primipara: the rates of primipara in Northeast China, North China and Southwest China were higher than the national average level, while those in South China, Central China and Northwest China were lower than the national average level. Non-Han nationality: the rates of non-Han nationality in Northeast China, North China and Northwest China were higher than the national average, while those in East China, South China and Central China were lower than the national average. Non-urban household registration: the rates of non-urban household registration in Northeast China, North China, and Southwest China were lower than the national average, while those in East China, Central China were higher than the national average. Irregular prenatal examination: the rates of irregular prenatal examination in North China, South China and Southwest regions were lower than the national average level, while those in Northeast China, Central China and Northwest China were higher than the national average level. History of PE: the incidence rates of PE in Northeast China, North China, South China and Southwest China were lower than the national average level, while those in Central China and Northwest China were higher than the national average level. Conclusions: Primiparas, non-Han, non-urban household registration, irregular prenatal examination, and PE history are risk factors for HDP pregnant women with organ or system impairment. Patients in Northeast, Central and Northwest China have more risk factors, and are more likely to be accompanied by organ or system function damage. It is important to strengthen the management of pregnant women and reduce the occurrence of HDP.

ABSTRACT

Objective To investigate the biologic viability and boundary range of hepatic alveolar echinococcosis (HAE) by the contrast-enhanced ultrasonography (CEUS) and acoustic radiation force impulse elastography (ARFI). Methods Totally 27 HAE patients confirmed by pathology underwent CEUS and ARFI examinations. Results Gray scale sonography of HAE showed unclear boundary, inhomogeneous, and middle hyperechoic nodules, and the maximum area was (6.08 ± 4.47) cm2 in 27 lesions. CEUS of HAE showed non-enhancement in three phases and black hole sign. Circumferential enhancement on the pe riphery of the lesion was synchronized with the liver parenchyma and showed “fast in and slow out”. The maximum area was (8.87 ± 4.83) cm2. The area of ECUS was larger than gray scale sonography in HAE (t = 2.20, P = 0.03). The mean shear wave velocities (SWVs) of the interior, the boundary range, and the surrounding liver tissues of HAE were statistically different by ARFI (F = 84.538, P < 0.001), and the interior had the highest values. Conclusions CEUS and ARFI examinations can detect the biologic viability and boundary range of migrating zone around HAE, which is valuable for guiding treatment, judging curative effect, and predicting prognosis.

ABSTRACT

Objective Dangerous placenta previa(PPP) combined with placenta implantation seriously threatens maternal life safety. This paper aim to explore the changes of MnSOD and SIRT3,the expression of SIRT3 in maternal placenta PPP combined with placenta implantation, and the relationship between trophoblast invasion and placental implantation. Methods 90 cases with placenta implantation of pernicious placenta previa were collected from January 2014 to June 2018 in Anhui Maternal and Child Health Hospital. According to the depth of placental villus invading uterine myometrium, 30 cases of placenta adhesion, 30 cases of placental implantation, and 30 cases of placenta penetration, 30 cases of normal control group.Immunohistochemical SP and Western blot were used to detect the expression of MnSOD and SIRT3 in placental tissues of the study group and the control group, then compared and analyzed. Results Compared with the control group, the expression of MnSOD and SIRT3 in the placental implantation group were increased. With the increasing of placental implantation degree, the level of MnSOD and SIRT3 decreased significantly (P<0.05). Western blot showed that , the relative protein expressions of MnSOD/β-actin and SIRT3/β-actin in the control group were (0.39±0.05) and (0.41±0.08), which were higher than those in the adhesion group[(0.35±0.04), (0.32±0.02)], the implantion group[(0.28±0.02), (0.20±0.03)], and the penetration group[(0.23±0.01), (0.17±0.02)]. The difference was statistically significant(P<0.05). Conclusion The expressions of MnSOD and SIRT3 incytoplasm or nucleus of invasive trophoblasts and placental tissues of pregnant women with placental implantation is significantly decreased, both of which are involved in the occurrence and development of placental implantation, but the specific pathogenesis still needs to be further explored.
