Objective The aim of this study was to evaluate the number of Treg cells in preeclamp-sia (PE) patients, to explore the expression levels of microRNA-210 (microRNA-210) and forkhead box p3 (Foxp3) genes in preeclampsia, and to reveal the regulatory mechanism of microRNA-210 and Foxp3 in preeclampsia. Methods Serum levels of cytokines [ interleukin ( IL)-6, IL-10, IL-17, and transforming growth factor-beta 1 (TGF-β1)] were detected with enzyme-linked immunosorbent assay (ELISA). 29 pa-tients with late-onset preeclampsia (≥36 weeks of gestation) , 27 pregnant women with normal uncomplicat-ed pregnancies (≥36 weeks of gestation) and 20 healthy non-pregnant women were enrolled in the study. Reverse-transcription polymerase chain reaction ( qRT-PCR) was performed to detect mRNA expression for maternal placenta retinoic acid-related orphan receptor C (RORc), Foxp3, and miR-210. Foxp3 protein expression was evaluated by Western blot. Results ⑴The serum levels of IL-6, IL-17 and TGF-beta 1 in preeclampsia patients were significantly higher than those in normal pregnant women, and the level of Treg cytokine IL-10 was lower than that in normal pregnant women ( P <0. 05 ) . ⑵ The percentage of CD4 +CD25 +CD127 - /CD4 +T cells in peripheral blood of preeclampsia patients was significantly lower than that of normal pregnancy group and healthy non-pregnant women ( P <0. 001 ) . ⑶ The mRNA expression of Foxp3 in placenta of preeclampsia patients was significantly lower than that of normal pregnant women, RORc in preeclampsia patients was significantly higher than that of normal pregnant women, and the expres-sion of microRNA210 in preeclampsia patients was enhanced ( P<0. 01 ) . ⑷ Consistent with mRNA ex-pression results, lower protein expression levels of Foxp3 was observed in patients with PE compared with normal pregnant subjects. Conclusions Treg cells decreased in preeclampsia patients and Treg/Th17 im-balance existed in preeclampsia patients, which regulate maternal immune tolerance to fetuses. The expres-sion of Foxp3 in placenta of preeclampsia patients was significantly decreased, which was correlated with the expression of microRNA-210.

BACKGROUND:The main clinical manifestation of senile arteriosclerosis obliterans is lower limb ischemia, which is currently difficult to treat. One method is by autologous stem cell transplantation into the muscles of ischemic limbs to improve the formation of new capillaries and restore lower limb blood flow. Endothelial progenitor cell marker CD34+ cell transplantation has been shown to promote angiogenesis in ischemic limbs. Therefore, we propose that peripheral blood autologous CD34+ cell transplantation in older adult patients with atherosclerotic ischemia could effectively promote angiogenesis.OBJECTIVE:To assume that peripheral blood autologous CD34+ cell transplantation in the elderly with atherosclerotic ischemia could effectively promote angiogenesis.METHODS:This is a prospective, single-center, open-label, randomized, and controlled clinical trial that will be completed at the Qingdao No. 9 People's Hospital, China. Twenty older adult patients with atherosclerotic lower limb ischemia will be randomized into two groups. In the cell transplantation group (n=10), peripheral blood CD34+ cells transfected with vascular endothelial growth factor 165 (VEGF165) gene will be intramuscularly transplanted into the ischemic limbs in older adult patients with atherosclerotic lower limb ischemia. In the control group (n=10), normal saline will be intramuscularly injected into the ischemic limbs. All patients will be followed up for 6 months. The primary outcome will be ankle-brachial indices before and 6 months after transplantation to assess lower limb ischemia in both groups.The secondary outcomes will be the number of microvessels in the lower limb muscles before and 6 months after transplantation, the morphology of new blood vessels revealed by CT angiography, the number of VEGF-immunoreactive cells 6 months after transplantation and the incidence of adverse reactions. The trial was registered at the ClinicalTrials.gov (identifier:NCT03098771), and the study protocol was approved by the Ethics Committee of Qingdao No. 9 People's Hospital of China. All protocols will be in accordance with Declaration of Helsinki,formulated by the World Medical Association. All patients will be informed of study protocols and provide a written informed consent prior to the beginning of the trial.DISCUSSION:This trial will begin in January 2018 and finish in December 2019. We aim to quantify the effects of VEGF165 gene-modified CD34+ cell transplantation in the treatment of older adult patients with atherosclerotic ischemia to develop a new effective treatment of lower limb ischemia.

Cardiac arrest in pregnancy is the emergency sereve case in clinic,which can threaten life and health of the fetus and pregnant women.Pregnancy cardiac arrest once happened,providing health care providers should start high quality chest compressions immediately,open the airway and commence ventilation,activate an emergency call system in which all providers in the maternal/neonatal resuscitation teams.We read from several aspects of 2014 the United States society for Obstetric Anesthesia and Perinatology consensus statement on the management of cardiac arrest in pregnancy in order to improve the cardiopulmonary resuscitation quality of pregnant women after cardiac arrest and optimize maternal and neonatal outcomes.

Objective: To evaluate the effectiveness and safety of the use of noninvasive high-frequency oscillation ventilation (nHFOV) in very low birth weight infants. Method: A total of 36 cases received nHFOV between January 2016 and October 2016 in Children′s Hospital, Zhejiang University School of Medicine, including 24 males and 12 females, with the gestational age of (27.5±2.5) weeks and birth weight of(980±318)g. The data of the ventilator settings, side effects, and changes of the respiratory function before and after nHFOV were collected and analyzed retrospectively. Nonparametric tests or t tests or χ² tests were used. Result: Thirty-two (89%) out of the 36 cases successfully avoided intubation or re-intubation after using of nHFOV. nHFOV was used as the rescue treatment after failure of other noninvasive ventilation in 17 cases, and as the prophylactical treatment preventing re-intubation after extubation in the remaining 19 cases. There were significant decreases in the incidences of apnea and desaturation(SpO₂<0.85), the level of PaCO₂, and the FiO₂ 24 h after the initiation of the nHFOV as the rescue therapy((1.2±1.1)vs.(6.3±2.1)episodes , (1.1±1.2) vs.(4.3±1.5) episodes, (43±8) vs.(56±10) mmHg, 0.30±0.07 vs. 0.39±0.11, respectively; 1 mmHg=0.133 kPa, t=7.562, 8.913, 4.179, 3.437 respectively, all P<0.01). No significant changes were found in FiO₂ and PaCO₂ levels 24 h after initiation of nHFOV as the prophylactical therapy after extubation (0.42±0.12 vs.0.40±0.10, (49±8)vs.(48±7)mmHg, t=0.872 and 0.501 respectively, both P>0.05), except for the significant decreases in the mean airway pressure ((7.9±2.6)vs.(9.6±1.6)cmH₂O, 1 cmH₂0=0.098 kPa, t=2.198, P=0.041). There were 4 cases suffered from nasal septum injury, while no other nHFOV related complications were noted. Conclusion nHFOV can be applied in preterm infants as a rescue treatment after the failure of other noninvasive ventilation, or prophylactically used in patients who have high risk of re-intubation.

Objective To establish the PDGF-BB-induced proliferation of rat pulmonary artery smooth muscle cells(PASMCs), and investigate the effects of the AMPK agonist AICAR on the cell cycle of PASMCs, in order to search new drugs for prevention of pulmo-nary vascular remodeling. Methods 20ng/ml PDGF-BB was used to induced the proliferation of PASMCs, and the effect of 0. 5mmol/L AICAR on the proliferation of PASMCs was observed. Western blot was used to detect the total and phosphorylated AMPK. The prolifer-ation of PASMCs was determined by CCK-8. The mRNA expression of cyclinD1, cyclinE and CDK2/4/6 were detected by flow cytometry analysis cell cycle,quantitative real-time PCR. Results Western blot Results indicated AICAR could promote the activation of AMPK. CCK-8 test Results showed that AICAR blocked the proliferation of PASMCs induced by PDGF-BB. Flow cytometry analysis indicated that AICAR arrested the cell cycle in G0/G1 to S phase. RT-PCR Results demonstrated that AICAR inhibited the mRNA expression of cy-clinD1, cyclinE and CDK2/4/6. Conclusion The AMPK agonist AICAR can block the proliferation of PASMCs induced through arrest cell cycle in G0/G1-S phase by regulation the mRNA expression of cyclin D1, cyclinE, CDK2/4/6, and AICAR has a potential applica-tion in preventing pulmonary vascular remodeling.

BACKGROUND:Mesenchymal stem cels isolated from cord blood and bone marrow have multi-directional differentiation ability under a certain condition of induction. OBJECTIVE:To compare the difference of differentiation of umbilical cord blood and bone marrow mesenchymal stem cels into osteoblasts. METHODS:Human umbilical cord blood and bone marrow mesenchymal stem cels were isolated and cultured by density gradient method. When reached 90% confluency, mesenchymal stem cels were digested by trypsin for subculture. At the third passage, umbilical cord blood mesenchymal stem cels and bone marrow mesenchymal stem cels at 8×104/wel were incubated. When reached 80% confluency, cels were treated with low-glucose DMEM supplemented with 10% fetal bovine serum, 0.1 μmol/L dexamethasone, 50 μmol/L vitamin C and 10 mmol/L β-sodium glycerophosphate. RESULTS AND CONCLUSION:There was no significant difference in morphology and biological properties of the two kinds of mesenchymal stem cels. Cels were highly expressed CD44, CD29, but did not express CD34. They had the ability to differentiate into osteoblasts, which had a positive staining for known markers: alkaline phospatase and calciumin vitro mineralization. There was no significant difference in the activity of osteoblasts of two kinds of cels. Results verify that umbilical cord blood and adult bone marrow mesenchymal stem cels can be induced into osteoblasts with a similar ability, and they can be used as seed cels for bone tissue engineering.
