Donor-derived CD19 CAR-T Cells versus Chemotherapy Plus Donor Lymphocyte Infusion for Treatment of Recurrent CD19-positive B-ALL After Allogeneic Hematopoietic Stem Cell Transplantation.

Objective: This study aimed to compare the efficacy of anti-CD19 chimeric antigen receptor T cells (CAR-T cells) versus chemotherapy plus donor lymphocyte infusion (chemo-DLI) for treating relapsed CD19-positive B-cell acute lymphoblastic leukemia (B-ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: Clinical data of 43 patients with B-ALL who relapsed after allo-HSCT were retrospectively analyzed. Twenty-two patients were treated with CAR-T cells (CAR-T group), and 21 with chemotherapy plus DLI (chemo-DLI group).

Dietary inflammatory index, inflammation biomarkers and preeclampsia risk: a hospital-based case-control study.

This study evaluated the association between inflammatory diets as measured by the Dietary Inflammatory index (DII), inflammation biomarkers and the development of preeclampsia among the Chinese population. We followed the reporting guidelines of the Strengthening the Reporting of Observational Studies in Epidemiology statement for observational studies. A total of 466 preeclampsia cases aged over 18 years were recruited between March 2016 and June 2019, and 466 healthy controls were 1:1 ratio matched by age (±3 years), week of gestation (±1 week) and gestational diabetes mellitus.

Dietary and serum vitamin D and preeclampsia risk in Chinese pregnant women: a matched case-control study.

The effect of vitamin D (VD) on the risk of preeclampsia (PE) is uncertain. Few of previous studies focused on the relationship between dietary VD intake and PE risk. Therefore, we conducted this 1:1 matched case-control study to explore the association of dietary VD intake and serum VD concentrations with PE risk in Chinese pregnant women.

The association between dietary fatty acid intake and the risk of developing preeclampsia: a matched case-control study.

The association between dietary fat intake during pregnancy and the risk of developing preeclampsia has been examined in many epidemiological studies, but the results remain inconsistent. The aim of this study was to clarify this association in pregnant Chinese women. After conducting 1:1 matching, 440 pairs consisting of pregnant women with preeclampsia and hospital-based, healthy pregnant women matched by gestational week (± 1 week) and age (± 3 years) were recruited.

miR424-5p functions as an anti-oncogene in cervical cancer cell growth by targeting KDM5B via the Notch signaling pathway.

Aims: Aberrant expression of miRNAs exert the critical roles in carcinogenesis, including cervical cancer. Recent study corroborated the down-regulation of miR424-5p in uterine cervix adenocarcinoma. This research aimed to investigate the function and underlying mechanisms of miR424-5p in cervical cancer cell growth.

Comparison of temporary abdominal aortic occlusion with internal iliac artery occlusion for patients with placenta accreta - a non-randomised prospective study.

Background: To compare the efficacy of temporary abdominal aortic occlusion with internal iliac artery occlusion for the management of placenta accreta.

Patients And Methods: 105 patients with placenta accreta were selected for treatment with temporary abdominal aortic occlusion (n = 57, group A) or bilateral iliac artery occlusion (n = 48, group B). Temporary abdominal aortic and internal iliac artery balloon occlusions were performed during caesarean sections.

Pseudomonas aeruginosa injection enhanced antitumor cytotoxicity of cytokine-induced killer cells derived from cord blood.

Cord blood (CB) is becoming an extensive source of cytokine-induced killer cells. It had been used in several clinical settings and proven to be efficacious and safe. Therefore, we investigated the possibility of combining CIK cells derived from cord blood (CB-CIK) and Pseudomonas aeruginosa injection (PA-MSHA) in order to enhance the cytotoxicity of CB-CIK cells against tumors.

The TLR3, PI3K, survivin, FasL, and Fas genes as major risk factors of occurrence and development of cervical cancer disease.

To investigate the role of TLR3/PI3K signals in the occurrence and development of cervical cancer disease, TLR3-siRNA was used to block key signaling pathways involved in cervical cancer metastasis that are pivotal to metastatic tumor cells but not to normal cells under ordinary physiologic conditions. Results show that tumor U14 cell growth, migration and invasion in TLR3-siRNA treatment group were significantly decreased. Through LY294002 suppressing targeted gene, the LY294002 treatment specifically and significantly knocked down the expressions of tumor TLR3 and PI3K proteins in cervical cancer mice.

[Expression and significance of AT1-AA and ET1 in materal peripheral blood, umbilical cord blood and placenta in preeclampsia].

Objective: To investigate the expression of autoantibodies to the angiotensin II type I receptor (AT1-AA) and endothelin-1 (ET-1) in pregnant women's blood and explore their correlation with the pathogenesis of preeclampsia.

Methods: Ninety pregnant women who delivered from June 2011 to December 2011 in the First Affiliated Hospital of Zhengzhou University were chosen as the study objects. They were divided into mild preeclampsia group (n = 30), severe preeclampsia group (n = 30) and normal group (control group, n = 30).

[Effect of DNA methyltransferase 1 gene silencing on proliferation and apoptosis of HeLa cells].

Objective: To observe the effect of DNA methyltransferase 1 (DNMT1) gene silencing by RNA interfering technology on the proliferation and apoptosis of HeLa cells.

Methods: Recombinant plasmid pshRNA-DNMT1-A, B and C were respectively transfected into HeLa cells by lipofectamine 2000, while cells transfected plasmid vector pSilencer3. 1-H1 and cells untreated as control groups.

[Promoter methylation of DAPK gene in cervical carcinoma].

Background & Objective: Aberrant DNA methylation plays important roles during multistage carcinogenesis in various human organs. This study was to explore the relationship between the promoter methylation and inactivation of DAPK gene in cervical cancer.

Methods: The promoter methylation of DAPK was investigated with methylation-specific polymerase chain reaction (MSP) in 52 specimens of cervical cancer, 60 specimens of cervical intraepithelial neoplasia (CIN) and 20 specimens of normal cervical squamous epithelial tissues.

[Vector construction and silencing effect of Edg4 gene targeted small interfering RNA in ovarian cancer cell line].

Objective: To construct the recombinant eukaryotic expression vector pRNAT-U6.1-siEdg4 which carries small interfering RNA (siRNA) of Edg4 and observe the silencing effect of Edg4 gene targeted siRNA in ovarian cancer cell line SKOV3.

Methods: The Edg4 gene-targeted hairpin siRNA sequence was designed according to the Edg4 sequence in Genbank, and the two complementary oligo nucleotide strands were synthesized and annealed and inserted into the pRNAT-U6.

[Expression and significance of P16INK4A and PTEN in high-risk human papillomavirus-related cervical cancer].

Background & Objective: High-risk human papillomavirus (HR-HPV) is the most important etiologic factor for cervical cancer. Recent studies have revealed that abnormal expression of tumor suppressor gene P16INK4A is closely associated with HR-HPV infection during carcinogenesis of cervical epithelium. Tumor suppressor gene PTEN is also involved in cervical tumorigenesis.
