Introduction: Mindfulness reflects attention to the present moment in a non-judgmental way and has been linked to individual autonomy and motivation, but conclusions are inconsistent. The purpose of this review was to summarize previous studies to explore the relationship between mindfulness and motivation and its intervention effects.
Methods: Literature searches were conducted in five electronic databases.
Aim: To assess the protective effect of human umbilical cord mesenchymal stem cell exosomes (hucMSC-Exs) in a diabetic rat model by using a variety of retinal bioassays.
Methods: hucMSCs were subjected to differential ultracentrifugation for the collection of exosomes, and transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) using a NanoSight analysis system and Western blotting (WB) were used to analyze the expression of surface marker proteins such as CD63, CD9 and Calnexin. Streptozotocin (STZ) was injected into the intraperitoneal cavity to establish a diabetic model.

rRNA gene high-throughput sequencing was performed in the conjunctival swab samples to investigate the composition of the OS bacterial community in DE (n=35) and NDE (n=54) and compared the composition of MGD (n=25) and NMGD (n=10) among DE subjects. Deep sequencing of OS 16S rDNA from DE (n=35) and NDE (n=54) demonstrated great a difference in alpha and beta diversity between the OS bacterial flora (P < 0.05).

Then gold nanoparticles (AuNPs) grafted with PLL--PNIPAM (PNIPAM-PLL-AuNPs) were obtained by the reduction of chloroauric acid with sodium citrate in the presence of PLL--PNIPAM. PNIPAM-PLL-AuNPs and its precursors were thoroughly characterized by proton magnetic resonance spectroscope, Fourier transform infrared spectroscope, UV-vis spectroscope, transmission electron microscopy, dynamic light scattering, thermogravimetric analysis, and circular dichroism.

Objective: To explore the relationship between the expression of Survivin and Ki67 with prognosis of pancreatic endocrine tumors (PETs).
Methods: Immunohistochemistry for Survivin and Ki67 was performed in 25 cases of normal pancreatic tissues and 81 cases of PETs by tissue microarrays and to observe the expression and evaluate the relationship with prognosis.
Results: (1)The expression of Survivin and Ki67 in PETs was significantly higher than that in normal pancreatic tissues (P <0.

Objective: To study the effects of Kangai injection on the enzyme activities of macrophages and morphology of spleen and thymus from rats.
Methods: Twenty four male SD rats were randomly divided into two groups (n = 12), normal control group and experimental group. The rats in experimental group were injected with Kangai injection at the dosage of 5 ml/kg x d for 30 days peritoneally and those in control group were injected with nomal saline at the same volume.
Background: Ventilator-associated pneumonia (VAP) is a common and serious problem in intensive care units. However, limited literature has been reviewed to synthesize the findings about the incidence, case fatality rate, pathogen distribution, and drug resistance of neonatal VAP in China.
Methods: A search of electronic databases was undertaken to identify the incidence, case fatality rate, pathogen distribution, and drug resistance of neonatal VAP based on the inclusion and exclusion criteria.
Insect additives have been shown to improve the value of artificial media for Trichogramma species, but at the same time maintain dependence on parallel cultures of host insects. In the present study, Trichogramma dendrolimi Matsumura was reared in vitro from egg to adult on artificial media with different contents of pupal hemolymph of Chinese oak silkmoth Antheraea pernyi (Guérin-Méneville) and with supplements of distilled water, or of trehalose dissolved in water or in Grace's insect medium. The results indicated insect hemolymph was the key component of artificial medium.

Methods: The diagnosed of autism was made according to the criteria of the ICD-10 and DSM-IV, with typical cluster of symptoms comprise social disability, communication impairments and repetitious behaviors. MLPA KIT P343-C1 AUTISM-1 was used to detect and describe the incidence of CNVs in these three domains.
The acute toxicities of five naphthoquinone compounds to Photobacterium phosphoreum were determined. We evaluated the mechanism of toxicity using the structure-activity relationship technique. The results showed that some factors, including the species of substituents, shape/size of molecule and oil-water partition coefficient (log P) played the important roles in the interaction between the naphthoquinones and the target.

Single nucleotide polymorphisms (SNPs) are the most common sequence variation in the human genome; they have been successfully used in mapping disease genes and more recently in studying population genetics and cancer genetics. In a population-based association study using high-density oligonucleotide arrays for whole-genome SNP genotyping, we discovered that in the genomes of unrelated Han Chinese, 34 out of 515 (6.6%) individuals contained long contiguous stretches of homozygosity (LCSHs), ranging in the size from 2.
