ABSTRACT
Uterine artery embolization (UAE) is an invasive radiological technique applied in treatment of gynecological and obstetric problems. Cesarean scar pregnancy, cervical pregnancy, and severe postpartum hemorrhage are common obstetric conditions that may require UAE. However, UAE could also cause various complications in clinical practice, some of which can lead to infertility in women, and even disability and death. According to the onset time, the complications are divided into three categories, namely onset-within-24-hour, early-onset, and late-onset complications in this review. Clinicians should be aware of and provide timely management of these complications when using this technique.
ABSTRACT
Background: Baicalein is an active compound extracted from the roots of Scutellaria baicalensis georgi, which is widely and traditionally used in the anticancer therapy. Notch signaling pathway is usually abnormally activated in kinds of human cancers. The aim of the present study is to investigate the antitumor effects of baicalein in human cervical cancer and explore whether baicalein treatment affects notch signaling pathway in human cervical cancers. Materials and Methods: Cervical cancer cells were treated with increasing concentrations of baicalein for 24, 48, and 72 h, respectively. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to determine cell viability of cervical cancer cells. The apoptosis rate was determined by FACS assay. Furthermore, the molecular mechanism was investigated. The expression levels of Notch 1, Notch 2, Notch 3, hairy enhancer of split-1 (Hes-1), and Hes-5 were determined by western blotting analysis. Results: MTT assay results revealed that baicalein inhibited cell proliferation of HeLa cells and SiHa cells in a time- and dose-dependent manner. The data from FACS assay demonstrated that baicalein-induced cell apoptosis of cervical cancer cells at the final concentration of 100 μM for 24 h. Furthermore, baicalein treatment downregulated Notch 1/Hes-1, Hes-5 signaling pathway, and there was no obvious change on the expression of Notch 2 and Notch 3. Conclusion: Baicalein inhibited the proliferation of human cervical cancer cells via Notch 1/Hes signaling Pathway. The study would provide some new clues in the clinical therapy of human cervical cancers
ABSTRACT
Objective To comparison of the safety of two treatment methods of cesarean scar pregnancy (CSP) of typeⅡ and Ⅲ in menopause within 7 weeks. Methods Totally 70 cases of CSP of typeⅡ and Ⅲ within 7 weeks of the last menstrual period, hospitalized within Peking University First Hospital from January 2009 to May 2016, had been retrospectively studied in two groups of different treatments. The methotrexate (MTX) treatment group included 37 cases receiving ultrasound-guided complete curettage of uterine cavity combined with MTX therapy, while the uterine artery embolization (UAE) group had 33 cases treated with UAE combined with MTX therapy and subsequent ultrasound-guided complete curettage of uterine cavity. The bleeding measurements during operation had been documented and compared for the study. Results The comparative difference of bleeding measurements between the MTX treatment group and the UAE group was insignificant from the statistical perspective (median: 5.0 vs 5.0 ml, P=0.716).The comparative difference of the duration (median: 2.0 vs 6.0 days, P<0.01) and expenses (median: 2832.1 vs 10147.1 yuan, P<0.01) for hospitalization between the MTX treatment group and the UAE group were significant from the statistical perspective. Conclusions The bleeding risks may not increase during the treatment of ultrasound-guided complete curettage of uterine cavity combined with MTX therapy for CSP patients of type Ⅱ and Ⅲwithin 7 weeks of the last menstrual period. Meanwhile, the UAE adverse effects and complications will be avoided, and the duration and expenses for hospitalization will be reduced.
ABSTRACT
Objective To investigate the effect of regulating peroxisome proliferator-activated receptor γγ (PPAR γ) on soluble endoglin (sEng) expression in first-trimester trophoblasts via an in vitro study.Methods Chorionic villus were collected from 20 samples of first-trimester artificial abortion in Peking University First Hospital from July 1 st to 31 st,2016.Primary culture of trophoblast cells was performed.Trophoblast cells from each sample were divided into three groups,which were PPAR γ antagonist group,PPAR γ antagonist and PPAR γ agonist group,and control group.Supematant sEng level was detected in each group by enzyme linked immunosorbent assay (ELISA).Paired-sample t test was used for statistical analysis.Results Compared with the control group,trophoblast cells in the PPAR γ antagonist group grew slower and were reduced in number.No significant difference in growth or morphology of trophoblast cells was observed between the PPAR γγ antagonist and PPAR γγ agonist group and the control group.Supernatant sEng level was elevated in the PPAR γ antagonist group,but was not significantly changed in the PPAR γ antagonist and PPAR γ agonist group as compared with that in the control group [(124.1 23.8) vs (94.0± 12.7) pg/ml,t=-4.31,P＜0.05;(87.1 ± 10.6) vs (94.0± 12.7) pg/ml,t=1.62,P=0.12).Conclusions Suppression of PPAR γ promotes sEng expression in trophoblast cells and that can be reversed by PPAR γ agonist.

ABSTRACT
Aim To investigate TH and GDNF genes expression and regulation of lentivirus ( Lv-TH-GDNF ) based on improved Tet-On system and the effect of the Lv-TH-GDNF intrastriatal transfer on a rat Parkinson’ s disease( PD) model. Methods 1. HeLa cells were infected by obtained Lv-TH-GDNF and rtTA2 s-M2 vi-rus. The expression of tyrosine hydroxylase ( TH ) and glial cell line-derived neurotrophic factor( GDNF) genes was induced by doxycycline( Dox) which was examined by Western blot. 2. The Lv-TH-GDNF together with rtTA2 s-M2 viruses were injected into lesion-side stria-tum of a rat PD model, and the expression of GDNF and TH genes was induced by Dox. Then, the effects of Lv-TH-GDNF were evaluated by the apomorphine-induced rotational behavior, the number of dopaminer-gic neurons in substantia nigra,DA and DOPAC levels in the lesion-side striatum. In addition, Western blot was performed to check the expression of TH and GD-NF genes in the transplanted striatum. Results 1. In vitro studies on HeLa cells, Western blot showed clear protein bands of TH and GDNF in the Dox-positive group, but not in the Dox-negative group. 2. In vivo experiments in animals, the results showed that, 4 weeks after transplantation, the apomorphine-induced turning effect was significantly improved ( P<0 . 01 ) , the number of TH-positive cells in the lesion-side sub-stantia nigra pars compacta as well as the content of DA and DOPAC, the protein level of GDNF and TH genes in the lesion-side striatum was significantly in-creased ( P<0 . 01 ) , each of which was only in Lv-TH-GDNF+rtTA2 s-M2+Dox-treated rats as compared with PBS-treated rats. Conclusion The expression of TH and GDNF genes in Lv-TH-GDNF based on im-proved Tet-On system is effectively regulated by tetra-cycline antibiotics without basal activity in vitro, and the intrastriatal transfer of which has certain therapeutic effect on PD rats.

ABSTRACT
Traditional T vector cloning method requires onerous procedures for identifying recombinant, and directional cloning was impossible. In order to overcome these problems, we have devised a directional T vector pETG based on pET-23a(+). For gene cloning, 7 bp partial LacO sequence was introduced into DNA fragment to reconstitute a full length LacO with Bfu I digested T vector. After transformation, blue colonies were selected on LB plate supplemented with X-gal. Restriction enzyme digestion and PCR identification showed that all blue colonies contained the directionally inserted recombinants and the recombinant efficiency was nearly 100%. We have successfully cloned 103 genes from human liver cDNA; in the study complicated procedures for screening of recombinant were not required. Eight pETG clones were picked for protein expression, and all the clones successfully produced corresponding proteins. We demonstrated that the directional T vector was successfully constructed, and it was very suitable for gene cloning and expression.

The expression of NF-kappaB is considered to be involved in the progress of neurodegeneration. It has been reported that Nanog can suppress the expression of NF-kappaB. To inspect and verify this finding, we constructed lentivirus (LV) vector that overexpressed the Nanog gene, infected mouse mesenchymal stem cells (mMSCs), and examined the influence of Nanog overexpression on NF-kappaB gene expression. The plasmid pNL-Nanog-IRES2-EGFP was constructed by double digestion and genetic recombination. Sequencing results confirmed that our cloned Nanog gene in the PNL-Nanog-IRES2-EGFP plasmid was consistent with the sequence reported in the GenBank. The three plasmids: pNL-Nanog-IRES2-EGFP, HELPER, and VSVG were cotransfected into 293T cells to produce LV particles. After co-transfection of the three lentiviral plasmids, green fluorescence was observed confirming successful transfection. The mMSCs were infected by the LV and the expression of Nanog was then also verified by the presence of green fluorescence. Nanog expression levels in the mMSCs were examined using Western blotting. Expression of NF-kappaB was also examined using RT-PCR and Western blotting, and in addition with fluorescent microscope after immunocytochemical staining. The levels of Nanog protein expression in Nanog-mMSCs were significantly increased, and the levels of NF-kappaB mRNA and protein expression in Nanog-infected mMSCs were significantly lower than those of Mock-mMSCs and the mMSCs control groups. Our findings suggest that mMSCs genetically modified to overexpress Nanog can lead to the suppression of NF-kappaB expression. This suppression of NF-kappaB could have important implications for the treatment of neurodegeneration, and hence further scientific investigations of these interactions will have significant impact on future clinical attempts to attenuate disease progression.
