ABSTRACT

Objective:To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China.Methods:Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women′s socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis.Results:A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95% CI: 4.5%-6.1%) and 13.1% (95% CI: 11.3%-14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions:In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

ABSTRACT

@#Alzheimer''s disease (AD) is the most common cause of senile dementia, accounting for an estimated 60% to 80% of cases, but there are no approved drugs to slow or stop the progressive clinical decline in the past years.Amyloid cascade hypothesis is recognized as the major etiologic basis for AD, however, the failures of several amyloid plaque-targeted programs have led many to dismiss the amyloid beta (Aβ) hypothesis of AD. Several reports show that soluble oligomers of Aβ (AβOs), which appear in brains more than 10 years before the clinical syndrome, are more toxic than Aβ plaque, causing synaptic dysfunction and neuronal apoptosis. Some agents that can effectively inhibit Aβ oligomer formation or block their toxicity made significant efficacy in clinical 2 and 3 trials, with the potential to be approved for the treatment of AD. This article reviews the recent development of AD drugs targeting Aβ oligomers, analyzes their structural characteristics, mechanism of action, preclinical and clinical data, and discusses the future direction of AD treatment, thus providing new strategies for AD drug research.

ABSTRACT

@#Alzheimer′s disease(AD)is a chronic neurodegenerative diseasecommonly seen in the elderlys. Several therapeutic drugs have failed in phase III clinical trials in recent years and there have been no efficient treatment for AD currently. Thus, there has been an urgent need for the effective methods of AD diagnosis at early stage. Developingnear-infrared fluorescentprobes for AD hallmarks detection has been a promising research field. In this review, we summarized a variety of near-infrared fluorescence(NIRF)probes reported in the past decade, which capable of detecting β-amyloid, Tau protein and reactive oxygen species, including their chemical strucutres、optical properties, in vitro and in vivo studies. Furthermore, we alsoraised some new directions for AD diagnosing. We believe that these new directions raised herein will benefit the future development of NIRF probes in the field of AD research.

ABSTRACT

@#Glucose-regulated protein 94(Grp94), an endoplasmic reticulum resident Hsp90 paralog, has a limited set of client proteins. Selective inhibition of Grp94 has emerged as a new direction for the development of drugs targeting the Hsp90 chaperone system. Now Grp94-Probe, an affinity-based probe of Grp94, was designed and synthesized based on DDO-5813, a most potent Grp94-selective inhibitor we found previously. Using fluorescence polarization(FP)assay and double staining assay with ER-Red in cells, we confirmed the binding of Grp94-Probe with ER Grp94. The FR results showed that the probe exhibited high affinity for Grp94N(EC50=117. 9 nmol/L)without exhibiting obvious Hsp90α inhibition, Moreover, as a fluorescence probe molecule, Grp94-Probe could better distinguish the inhibitory activity of compounds for Grp94N. The results of fluorescence analysis in cells showed that Grp94-Probe could co-stain with ER-Red in the endoplasmic reticulum, and the fluorescence did not decay rapidly with time after 4 h of staining, which further indicated the binding of Grp94-Probe with Grp94 in cells. This Grp94 selective probe can be further used for biology evaluation of Grp94 inhibitor and exploration of Grp94 biological functions.

ABSTRACT

Objective To investigate the value of abdominal aortic balloon combined homeostasis in the cesarean section with invasive completeplacenta previa. Methods Data of 47 cases of completeplacenta previa with placenta accrete from March 2007 to August 2018 were analyzed retrospectively. Seventeen cases (study group) were treated with abdominal aortic balloon combined homeostasis before cesarean, and 30 cases (control group) did not receive balloon occlusion. The operation time, intra-operative blood loss, intra-operative blood transfusion volume, disseminated or diffuse intravascular coagulation (DIC) rate, hysterectomy rate and post operative complications, time of postoperative hospital stay were compared. Also, the blood coagulation parameters 24 h after operation, including activated partial thromboplastin time (APTT), fibrinogen (FIB), D-dimer werecompared between the two groups. Results Significant difference was observed in the blood loss [1 000 (800—2 000) ml vs. 2 200 (1 000-4 100) ml, Z=-2.272, P=0.023] and blood transfusion volume [400 (0-2 450) ml vs. 2 460 (200-4 460) ml, Z =- 2.02, P = 0.03], 16 cases of the study group still bled after releasing the balloon.Fifteen cases of them received uterine artery ligation. Bleeding stopped after uterine balloon compression in 1 case. Eleven cases of the 15 cases received uterine balloon compression at the same time. One case of 28 weeks gestation underwent subtotal hysterectomy due to hemorrhagic shock combined with DIC caused by placenta accretion of the bladder. While in control group, 7 cases underwent total hysterectomy because hemorrhagic shock combined with DIC and 3 cases underwent subtotal hysterectomy due to heavy bleeding, and there was statistical significance between two groups [1/17 vs. 33.3%(10/30), P=0.039]. Conclusions Temporary balloon occlusion of the abdominal aorta combined with conventional homeostasis can reduce blood loss, blood transfusion and hysterectomy rate in the cesarean section complicated with invasive complete placenta previa.

ABSTRACT

Objective To investigate the effect of supine regulating on maternal fetal occiput posterior position during the delivery after epidural analgesia. Methods Totally600 cases of parturient with intravaginal posterior occipital position with 3cm voluntary labor analgesia were selected,who were born in Dalian maternity hospital from October 2015 to October 2016.The(Visual Analogue Scale/Score) VAS pain score at 15min after epidural labor analgesia was as effective as less than 3 points.They were randomly divided into the control group and the observation group by random number table method,with 300 cases in each group.The control group monitored parturient respiration, pulse, blood pressure, heart rate and fetal heart rate according to routine treatment.The control group monitored parturient respiration, pulse, blood pressure, heart rate and fetal heart rate according to routine treatment.In the observation group,except for routine treatment according to the labor process,after the opening of 5cm,the pregnant women were instructed to take the lateral prone position,so that the maternal side and the fetal side of the spinal column should be the same side. To observe the difference between the two groups in the rate of spontaneous vaginal delivery, delivery rate, cesarean section rate, fetal cardioversion rate, time of birth process and neonatal Apgar score. Results Totally 283 cases delivery through vagina and 17 cases of cesarean section in observation group,while 257 cases of vaginal delivery and 43 cases of cesarean section in the control group.The successful rate of fetal position transfer in the observation group was 74.6%(211/283) which was significantly higher than 45.9% (118/257) of the control group (Χ2=62.782, P<0.01), natural labor rate was also 87.3% (262/300) which increased significantly according to 64.7% (194/300) (Χ2=42.251, P<0.01),the rate of midwifery (7.0%, 21/300) and cesarean section (5.7%, 17/300) were significantly lower than 21.0% (63/300)and 14.3% (43/300) of the control group (Χ2=24.419, 12.519,P<0.01),the second stage of labor was(1.60±0.56)h which was significantly shortened than(2.19±0.53)h also(t=-12.589,P<0.01).In the observation group, the ratio of the posterior occipital position to the occipital transverse position after the opening of 8-10 cm and the complete dilation of the cervical were 7.4%(21/283)and 13.1%(37/283),which were also significantly increased than 3.4%(9/264),6.8%(18/264) of the control group (Χ2=4.240, 5.911, P<0.05). Conclusions Supine adjustment after the cervix dilatation larger than 5cm is more conducive to fetal rotation and to avoid the adverse complications, reduce the rate of vaginal delivery and cesarean section rate,improve the rate of natural childbirth,shorten delivery time,improve the quality of delivery.

ABSTRACT

The application of medical imaging technology is playing an important role in diagnosis and treatment of cancer.In clinic,the most commonly used imaging technology to detect cancers are X-ray computed tomo graphy,nuclide imaging,magnetic resonance imaging and near-infrared fluorescence imaging.Contrast agents could enhance imaging signals and increase the sensitivity and accuracy of cancer detection.Neverthness,most of clinically used contrast agents have problems such as short retention time and tumor targeting insufficient,which is not favorable to cancer detecting.So it is of great significance to develop tumor targeting contrast agents.Currently,targeting strategies are divided into three types:passive targeting,active targeting and activatable targeting.In this review,we conclude the recent progress and applications of tumor targeting contrast agents of different imaging modilities.Besides,the future development of tumor targeting contrast agents is also prospected.

ABSTRACT

To determine the association of high birth weight [HBW] with the risk of obesity in childhood and adolescence. We also aimed to explore the interactions of HBW with physical activity and dietary habits. In a birth cohort born in 1993, 1994, and 1995 in Wuxi, China, subjects with a birth weight [BW] of >/= 4000 g were selected as the exposed group. For each exposed subject, one non-exposed subject with a BW of 2500-3999 g, matched by year of birth, gender, and type of institute at birth was chosen. Two follow-ups were performed from October 2005 to February 2007 and July 2010 to December 2011. A total of 1108 exposed and 1128 non-exposed subjects were included. Overweight/obesity rates were significantly higher in the exposed group [16.2% in childhood and 14.2% in adolescence] than those in the non-exposed group [12.1% in childhood and 8.2% in adolescence]. There was no significant interaction between BW and the growth period [F=2.10, p=0.147]. The relative excess risk due to interaction [RERI] of HBW with physical activity was -0.20 [95% CI=-2.85-2.45], and the RERI of HBW with dietary habits was 1.19 [95% CI=0.14-2.23]. Infants with HBW are at increased risk of childhood and adolescent overweight/obesity, and this relationship is not influenced by the growth period. There is an additive interaction between HBW and dietary habits

ABSTRACT

The aim of the study was to explore the mechanisms underlying the association of birth weight with later body mass index [BMI] from the biochemical markers related to metabolism and the Apa I polymorphism in IGF-II gene. A total of 300 children were selected randomly from the Macrosomia Birth Cohort in Wuxi, China. The height and weight were measured and blood samples were collected. Plasma concentrations of 8 biochemical markers were detected. Apa I polymorphism was analyzed by polymerase chain reaction-restriction fragment length polymer-phism [PCR-RFLP]. Biochemical markers were detected for 296 subjects and 271 subjects were genotyped for the Apa I polymorphism. No association was found between birth weight and 8 biochemical markers. In boys, the BMIs of AA, AG and GG genotypes were 16.10 +/- 2.24 kg/m[2], 17.40 +/- 3.20 kg/m[2], 17.65 +/- 2.66 kg/m[2]. And there was statistical difference among the three genotypes. But in girls, there was no statistical difference. The birth weights of AA, AG and GG genotypes were 3751.13 +/- 492.43 g, 3734.00 +/- 456.88 g, 3782.00 +/- 461.78 g. And there was no statistical difference among the three genotypes. Biochemical markers are not associated with birth weight. Apa I polymorphism may be related to childhood BMI, but it may be not associated with birth weight. Therefore, biochemical markers and Apa I polymorphism might not play a role in the association of birth weight and BMI
