The formation mechanism and textural properties of a complex gel based on soybean glycinin-chitosan complex coacervates: Effects of pH, heat treatment temperature and centrifugation.

The soybean glycinin (11S)-chitosan (CS) complex gels with various textural properties were successfully constructed. The process involved the initial formation of 11S-CS coacervates through electrostatic interactions, followed by a heating treatment to obtain the final complex gels. The impacts of pH, heating temperature, and centrifugation on 11S-CS complex gel properties were investigated.

Injectable collagen scaffold with human umbilical cord-derived mesenchymal stem cells promotes functional recovery in patients with spontaneous intracerebral hemorrhage: phase I clinical trial.

Animal experiments have shown that injectable collagen scaffold with human umbilical cord-derived mesenchymal stem cells can promote recovery from spinal cord injury. To investigate whether injectable collagen scaffold with human umbilical cord-derived mesenchymal stem cells can be used to treat spontaneous intracerebral hemorrhage, this non-randomized phase I clinical trial recruited patients who met the inclusion criteria and did not meet the exclusion criteria of spontaneous intracerebral hemorrhage treated in the Characteristic Medical Center of Chinese People's Armed Police Force from May 2016 to December 2020. Patients were divided into three groups according to the clinical situation and patient benefit: control (n = 18), human umbilical cord-derived mesenchymal stem cells (n = 4), and combination (n = 8).

Three-dimensional bioprinting collagen/silk fibroin scaffold combined with neural stem cells promotes nerve regeneration after spinal cord injury.

Many studies have shown that bio-scaffolds have important value for promoting axonal regeneration of injured spinal cord. Indeed, cell transplantation and bio-scaffold implantation are considered to be effective methods for neural regeneration. This study was designed to fabricate a type of three-dimensional collagen/silk fibroin scaffold (3D-CF) with cavities that simulate the anatomy of normal spinal cord.

Prognostic and predictive value of tumor-infiltrating lymphocytes for clinical therapeutic research in patients with non-small cell lung cancer.

Background: Previous preclinical and clinical studies have shown that levels of tumor-infiltrating lymphocytes (TILs) significantly correlated with prognosis in non-small cell lung cancer (NSCLC), and survival after therapy; however, this finding remains controversial. We performed a meta-analysis, to evaluate, systematically, the clinical utilization of TIL subtypes in patients with NSCLC.

Methods: The PubMed, ISI Web of Science, EMBASE, and Cochrane Library databases were searched to identify relevant studies.

[Distribution and activation of dendritic cells in immune thrombocytopenia patients].

Defective dendritic cell (DC) functions have been implicated in ITP. The purpose of this study was to investigate the distribution and activation of dendritic cells in immune thrombocytopenia (ITP) patients. ITP patients were divided into 3 groups: the newly diagnosed, refractory and effective treatment group.

The effects of bisphenol A (BPA) exposure on fat mass and serum leptin concentrations have no impact on bone mineral densities in non-obese premenopausal women.

Objectives: Bisphenol A (BPA) exposure may promote obesity, but its effect on bone mineral density (BMD) has not been reported in humans. We aimed to examine the relationships between BPA exposure, body composition, serum estradiol, leptin, osteocalcin levels and BMDs in healthy premenopausal women.

Design And Methods: In this cross-sectional study, a total of 246 healthy premenopausal women aged 20 years and older with regular menstrual cycles were investigated.

[Correlation of CD19 positive cell counts in bone marrow with therapeutic efficacy in patients with multiple myeloma].

This study was aimed to analyze the correlation of CD19 positive cell counts in bone marrow of multiple myeloma(MM) patients with therapeutic efficacy and investigate the characteristics of CD19 cell change in MM bone marrow. The CD19(+) and CD38(++)CD45(-), CD38(++)CD45(-)CD56(+) cells in bone marrow of 63 MM patients were detected by flow cytometry. The difference of CD19(+), CD38(++)CD45(-), CD38(++)CD45(-)CD56(+) cell counts at different stages and types, as well as their relation with results of 4 course of VADM or VD chemotherapy were analyzed.

[The role of B cell-activating factor secreted by peripheral blood monocyte-derived dendritic cell in chronic idiopathic thrombocytopenic purpura].

Objective: To explore the characteristics of B cell-activating factor (BAFF) secreted by peripheral blood monocyte-derived dendritic cell (MoDC) in chronic idiopathic thrombocytopenic purpura (cITP) and the function of MoDC on B cell proliferation.

Methods: Ten cITP patients were studied dynamically before and after treatment. The BAFF levels in serum and the supernatant of LPS stimulated MoDC were tested with ELISA.

[The relation between Bence Jones protein gene polymorphism and function of renal tubular-epithelial cell in multiple myeloma].

Objective: Bence Jones protein (BJP) plays an important role in multiple myeloma (MM) renal lesion, we try to study the relation between the characteristics of BJP variable gene and the function of renal tubular-epithelial cell (TEC).

Methods: MM patients whose function of TEC was abnormal at diagnosis constituted a group damage and patients whose function of TEC was normal for a long period a group normal. We also collected MM patients and divided them into a group BJPkappa and a group BJPlambda.

[Spectroscopic study on the time evolution behaviors of the laser-induced air plasma].

The time-resolved spectra of the air-breakdown plasma produced by the 1.06 microns beam of a Nd:YAG laser were investigated by using the time-delayed spectra and the spectral line evolution methods. The time evolutions of the short wavelength band and long wavelength band of the continuous spectra of the air-breakdown plasma have been measured.
