Conductive flexible hydrogels have attracted immense attentions recently due to their wide applications in wearable sensors. However, the poor mechanical properties of most conductive polymer limit their utilizations. Herein, a double network hydrogel is fabricated via a self-sorting process with cationic polyacrylamide as the first flexible network and the lantern[3]arene-based hydrogen organic framework nanofibers as the second rigid network.

Since May 2022, monkeypox cases have been reported in more than 96 non-endemic countries and regions worldwide.

The correlation between the antibiotic concentration and water quality indexes was analyzed and the ecological risks were evaluated. The results showed that only six antibiotics were detected in the entry section of Harbin city on the Songhua River and the concentration was relatively low.

Its' important applications are to neutralize the heparin in human blood and analyze heparin structure in the clinic. However, the low productivity and activity of the enzyme have greatly hindered its applications.

With accumulated experiences in the diagnosis and treatment of COVID-19 in children, we have updated the consensus statement and released the second edition recently. The current version in English is a condensed version of the second edition of consensus statement on diagnosis, treatment and prevention of COVID-19 in children.

Data on epidemiology of paediatric MPP from China are little known. This study retrospectively collected data from June 2006 to June 2016 in Beijing Children's Hospital, Capital Medical University of North China and aims to explore the epidemiological features of paediatric MPP and severe MPP (SMPP) in North China during the past 10 years.

Methods: Pediatric patients with CGD from Beijing Children's Hospital, Capital Medical University, China, were enrolled from January 2006 to December 2016.
Purpose: The aim of this study was to identify critical genes in lung cancer progression.
Methods: We downloaded and reanalyzed gene expression profiles from different public data-sets using comprehensive bioinformatics analysis. Differentially expressed genes (DEGs) were identified in lung adenocarcinoma tissues compared with adjacent nonmalignant lung tissues.
Shaker-like K outward rectifying channel (SKOR) is involved in mediating long-distance K transport from roots to shoots. In this study, a Shaker-like outward K channel gene CmSKOR (GenBank accession number MF447462) was isolated from melon (Cucumis melo L.).

Methods: Hospitalized patients with disseminated cryptococcosis were enrolled during January 1996 to December 2015 in Beijing Children's Hospital, Capital Medical University, China.
Auxin resistant 1/like aux1 (AUX/LAX), pin-formed (PIN) and ATP binding cassette subfamily B (ABCB/MDR/PGP) are three families of auxin transport genes. The development-related functions of the influx and efflux carriers have been well studied and characterized in model plants. However, there is scant information regarding the functions of auxin genes in Chinese cabbage and the responses of exogenous polar auxin transport inhibitors (PATIs).

Although intensive studies has been on head formation in Chinese cabbage in the past decade, very scanty information is available on mechanism involved in the head formation under the influence of low temperature at transcriptome and proteome perspective. In this study, quantitative expression profiling based on RNA-Seq transcriptome and iTRAQ proteome were combined to investigate this trait for a global picture of the molecular dynamics.

Objective: In this study, we try to find the better protocol of limb ischemia postconditioning by observing different protective effects of limb ischemic postconditioning (different strength and time windows in rabbits).
Methods: 42 healthy New Zealand rabbits were randomly divided into 7 groups (n = 6): Sham; Control (CON); Skeletal muscle postconditioning (SP); 6 min-delayed skeletal muscle postconditioning (6M-DSP); 1 min-delayed skeletal muscle postconditioning (1M-DSP); Strengthen skeletal muscle postconditioning (SSP); Weakened skeletal muscle postconditioning (WSP). Acute ischemia/reperfusion (I/R) model was induced by 45 minutes occlusion on left circumflex coronary artery (LCX) and 2 hours reperfusion in all anesthetized open-chest rabbits except the Sham.
