The effect of early-onset sepsis on retinopathy of prematurity in extremely premature infants based on propensity score matching.

To investigate the effects of early-onset sepsis (EOS) on retinopathy of prematurity (ROP) in extremely premature infants (EPIs) by using propensity score matching (PSM). Clinical data of 591 EPIs admitted to NICU, Senior Department of Pediatric, PLA General Hospital from May 1, 2015 to May 1, 2022 were retrospectively analyzed. They were divided into an EOS group and a non-EOS group according to whether they had confirmed EOS or not.

[Construction of a mouse model of type 2 diabetes induced by high fat diet alone and evaluation of pathological changes].

The purpose of the present study was to investigate the modeling time of type 2 diabetes mellitus (T2DM) mouse model induced by high fat diet (HFD) alone and the effects of HFD on the pathology and function of organs related to glucose and lipid metabolism. C57BL/6 mice were fed with normal diet (NC group) or HFD (HFD group). The time of successful T2DM modeling was evaluated by measuring body weight, fasting blood glucose and glucose tolerance at time points of 0, 4, 8, 12, 16 and 20 weeks.

ATG5 attenuates inflammatory signaling in mouse embryonic stem cells to control differentiation.

Attenuated inflammatory response is a property of embryonic stem cells (ESCs). However, the underlying mechanisms are unclear. Moreover, whether the attenuated inflammatory status is involved in ESC differentiation is also unknown.

The nonautophagic functions of autophagy-related proteins.

ATG: autophagy related; BECN1: beclin 1; cAMP: cyclic adenosine monophosphate; dsDNA: double-stranded DNA; EMT: epithelial-mesenchymal transition; IFN: interferon; ISCs: intestinal stem cells; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAPK/JNK: mitogen-activated protein kinase/c-Jun N-terminal kinases; MTOR: mechanistic target of rapamycin kinase; STING1: stimulator of interferon response cGAMP interactor 1; UVRAG: UV radiation resistance associated; VPS: vacuolar protein sorting.

The Syntheses and Spectroscopic Properties of the Styryl Quinoline Derivatives.

The simple method of the syntheses of the styryl quinoline derivatives was developed. The intermediate of 2-methylquinoline was synthesized from 10 mmol aniline and 20 mmol (E)-2-Butenal dissolved in 8 mL methylbenzene refluxing at 100 ℃ for 3 hours with 10 mL 6 M hydrochloric acid as catalyst. Eight derivatives were obtained in 15 mL glacial acetic acid using 2-methylquinoline (10 mmol) and aromatic aldehyde (12 mmol) as materials refluxing for 8 hours with a yield of 71%～88%.

[Analysis of the risk factors for hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation for beta-thalassemia in children].

Objective: To analyze the risk factors of hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation for beta-thalassemia in children.

Methods: The clinical records of 30 children with beta-thalassemia undergoing allogeneic hematopoietic stem cell transplantation between December, 2008 and November, 2009 were analyzed.

Results: Hemorrhagic cystitis occurred in 8 of the 33 patients with an incidence of 24.

[The expansion and biological characteristics of human mesenchymal stem cells].

Objective: Mesenchymal stem cells (MSCs) were adult stem cells which contribute to the regeneration of mesenchymal tissues such as bone cartilage, muscle, ligament, tendon, adipose and stroma. Due to the multipotential ability and self-renewal capacity, the mesenchymal stem cells can be applied in many fields, such as the seed cells in tissues engineering, cell therapy and gene therapy. To enhance the clinical use of MSCs, the investigators studied the isolation and expansion of MSCs from adult bone marrow, fetal bone marrow and human umbilical cord blood, and investigated their biological identities.

[The experimental study on inducing and expanding T/NK cells from mononuclear cells of human umbilical cord blood].

Objective: To explore the most efficient culture system which can induce cord blood (CB)-mononuclear cells (MNC) to differentiate into mature T/NK cells in vitro.

Methods: The CB MNCs were cultured in six culture systems respectively for 4 weeks. The T/NK cell surface phenotypes were analyzed by flow cytometry and the absolute numbers of nucleated cells (NCs) were counted at each time point.
