[Epidemiological investigation of iron deficiency among preschool children in 10 provinces, autonomous regions, or municipalities in China].

To understand the current status of anemia, iron deficiency, and iron-deficiency anemia among preschool children in China. A cross-sectional study was conducted with a multi-stage stratified sampling method to select 150 streets or townships from 10 Chinese provinces, autonomous regions, or municipalities (East: Jiangsu, Zhejiang, Shandong, and Hainan; Central: Henan; West: Chongqing, Shaanxi, Guizhou, and Xinjiang; Northeast: Liaoning). From May 2022 to April 2023, a total of 21 470 children, including community-based children aged 0.

The mutual regulatory loop between TPTEP1 and miR-1303 in leukemogenesis of acute myeloid leukemia.

Background: Non-coding RNAs (ncRNAs) have been identified as key regulators during the pathogenesis and development of cancers. However, most of ncRNAs have never been explored in acute myeloid leukemia (AML).

Methods: Gene expression was evaluated by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot.

Long-term results of a randomized, double-blind, and placebo-controlled phase III trial: Endostar (rh-endostatin) versus placebo in combination with vinorelbine and cisplatin in advanced non-small cell lung cancer.

Background:  : Phase II-III trials in patients with untreated and previously treated locally advanced or non-small cell lung cancer (NSCLC) suggested that Endostar was able to enhance the effect of platinum-based chemotherapy (NP regimen) with tolerable adverse effects.

Methods: Four hundred and eighty six patients were randomized into two arms: study arm A: NP plus Endostar (n = 322; vinorelbine, cisplatin, Endostar), and study arm B: NP plus placebo (n = 164; vinorelbine, cisplatin, 0.9% sodium chloride).

Effect of polymerization degree of calcium polyphosphate on its microstructure and in vitro degradation performance.

Preparation, characterization and in vitro study of a series of calcium polyphosphate (CPP) with different polymerization degree were reported. A series of CPP with different polymerization degree were prepared by controlling calcining time. Average polymerization degree was analyzed by liquid state 31P nuclear magnetic resonance (NMR).

[Evaluation of blood compatibility of surface modification treated poly (D, L-lactic and glycolic acid) with mPEG block copolymer].

To identify the advantages of modification treated poly (D, L-lactic and glycolic acid) with poly (ethylene glycol) (PLGA/mPEG, PELGA) block copolymer, blood compatibility was evaluated in vitro. Three different proportional block copolymers (LA/GA80: 20, 70: 30, 50: 50) with 15% mPEG were synthesized. According to the international standard organization (ISO10993) and National Standards of P.

The early changes of colon motility in the rats after liver transplantation.

The purpose of this study was to explore the early changes of colon motility in rats after liver transplantation. Thirty Wistar rats were divided into a sham operation group (n = 10) and a liver transplantation group (n = 10 pairs). The number of stools, the contractility of muscle strips, the length of smooth muscle cells, the levels of plasma endotoxin, the morphological changes, and the expression of inducible nitric oxide synthase (iNOS) in the colon of the rats were observed in the two groups.

Preliminary experience in adult-to-adult living donor liver transplantation in a single center in China.

The aim of this paper is to report the authors' experience in performing adult-to-adult living donor liver transplantation (LDLT) by using a modified technique in using grafts of the right lobe of the liver. From January 2002 to September 2006, 56 adult patients underwent LDLT using right lobe grafts at the West China Hospital, Sichuan University Medical School, China. All patients underwent a modified operation designed to improve the reconstruction of the right hepatic vein (RHV) and the tributariers of the middle hepatic vein (MHV) by interposing a vessel graft, and by anastomosing the hepatic arteries and bile ducts.

[Effect of isorhmnetin on circadian rhythms of DNA synthesis and expression of c-myc gene in Eca-109 cells of human oesophageal cancer].

This study was focused on the circadian rhythms of DNA synthesis and the expression of c-myc gene in untreated and treated Eca-109 cells in human oesophageal cancer with isorhmnetin. The circadian rhythms of 3H-TdR incorporation and expression of c-myc gene in untreated and treated Eca-109 cells were measured by 3H-thymidine uptake assay and flow cytometry. The data collected were analyzed by ANOVA and Cosinor method.
