[Characteristics, Risk Assessment of Microplastics, and Heavy Metal Pollution in Farmland Soils in the Upper Hanjiang River].

To investigate the pollution of microplastics and heavy metals from farmland soils in the upper Han River, the pollution status and distribution characteristics of pollutants were systematically analyzed. The risk level of pollutants was evaluated using methods such as the potential ecological risk index （RI）. Source apportionment was identified using correlation analysis and cluster analysis.

NLRP3-Mediated Piezo1 Upregulation in ACC Inhibitory Parvalbumin-Expressing Interneurons Is Involved in Pain Processing after Peripheral Nerve Injury.

The anterior cingulate cortex (ACC) is particularly critical for pain information processing. Peripheral nerve injury triggers neuronal hyper-excitability in the ACC and mediates descending facilitation to the spinal dorsal horn. The mechanically gated ion channel Piezo1 is involved in the transmission of pain information in the peripheral nervous system.

Study on the Effect of Molecular Weight on the Gut Microbiota Fermentation Properties of Blackberry Polysaccharides In Vitro.

This study aimed to investigate the effect of different molecular weights on the metabolic characteristics of blackberry polysaccharides (BBP). After degradation, three fractions, namely, BBP-8, BBP-16, and BBP-24, were obtained. During fermentation, all polysaccharide fractions were significantly degraded and utilized by the intestinal microbiota, and the lower-molecular-weight polysaccharides were easier to be fermented with higher gas production and carbohydrate consumption rates.

Neuroimmune Mechanisms Underlying Neuropathic Pain: The Potential Role of TNF-α-Necroptosis Pathway.

The neuroimmune mechanism underlying neuropathic pain has been extensively studied. Tumor necrosis factor-alpha (TNF-α), a key pro-inflammatory cytokine that drives cytokine storm and stimulates a cascade of other cytokines in pain-related pathways, induces and modulates neuropathic pain by facilitating peripheral (primary afferents) and central (spinal cord) sensitization. Functionally, TNF-α controls the balance between cell survival and death by inducing an inflammatory response and two programmed cell death mechanisms (apoptosis and necroptosis).

Neuroinflammation in the anterior cingulate cortex: the potential supraspinal mechanism underlying the mirror-image pain following motor fiber injury.

Background: Peripheral nerve inflammation or lesion can affect contralateral healthy structures, and thus result in mirror-image pain. Supraspinal structures play important roles in the occurrence of mirror pain. The anterior cingulate cortex (ACC) is a first-order cortical region that responds to painful stimuli.

[Preparation of a New Type of Silk Birth-canal Microecology Transporter].

Objective: To optimize the preparation parameters of the new silk birth-canal microecology transporter (BMT) for transferring the symbiotic bacteria of the birth canal efficiently.

Methods: Birth canal microbial samples of 30 full term pregnant women at admission were collected as the control group (NC, =30). The experimental group included 18 pregnant women terminated by Cesarean section, who were divided into 6 sub-groups （M1-M6, =3) to complete the transfer tests of the birth-canal microecology.

[Allocation of rice photosynthates in plant-soil system in response to elevated CO and nitrogen fertilization].

To examine the allocation of rice photosynthates and its response to the elevated CO (800 μL·L) and N fertilization (100 mg·kg) at both tillering stage and booting stage in plant-soil system, rice was continually labelled with CO. The results showed that the rice root biomass at the tillering stage and the shoot biomass at the booting stage were significantly increased under elevated CO. Elevated CO increased the rice biomass and root-shoot ratio at tillering stage, but reduced it at booting stage.

Identification and Pathogenicity of Fungal Pathogens Causing Black Point in Wheat on the North China Plain.

Fungi associated with black point were isolated from three highly susceptible wheat genotypes in the North China Plain. The 21 isolates represented 11 fungal genera. The most prevalent genera were (isolation frequency of 56.

[Characteristics and Influencing Factors of Biologically-based Phosphorus Fractions in the Farmland Soil].

A suitable fractionation method of phosphorus (P) is a key to effective assessment of soil P componential features. Here a new biologically-based P (BBP) method was used to evaluate the P fractions in the upland and paddy soils across large-scale area in China. The soil P was divided into four components:① soluble or rhizosphere-intercepted (CaCl-P), ② organic acid activated and inorganic weakly bound (Citrate-P), ③ enzyme mineralization of organic P (Enzyme-P), ④ potential activation of inorganic P (HCl-P).

Transcriptome Analysis for Abnormal Spike Development of the Wheat Mutant dms.

Background: Wheat (Triticum aestivum L.) spike development is the foundation for grain yield. We obtained a novel wheat mutant, dms, characterized as dwarf, multi-pistil and sterility.

[Expression of BRAF V600E mutation in different thyroid lesions].

Objective: To evaluate the expression of BRAF V600E mutation in 240 Chinese patients with thyroid lesions.

Methods: Two hundred and forty Chinese patients with thyroid lesions, including 129 papillary thyroid carcinomas (PTC), 12 follicular carcinomas, 4 medullary carcinomas, 30 adenomas, 30 nodular goiters, and 35 papillary hyperplasia. DNA was extracted from thyroid biopsy and paraffin embedded thyroid tissues, and the expression of BRAF V600E mutation was detected by polymerase chain reaction and DNA sequencing assays.

[Effect of ginsenoside Rg1 on angiogenesis after neonatal hypoxia ischemia brain damage in rats].

Objective: To investigate effects of ginsenoside Rg1 on angiogenesis in neonatal rats with hypoxia ischemia brain damage (HIBD), and explore the possible mechanism.

Methods: Fifty-four of 10-day-old SD rats were randomly divided into sham-operation group (n = 6), hypoxia-ischemia brain damage group (n = 24) and ginsenoside Rg1 treatment group (n = 24). SD rats in HIBD group and Rg1 group were treated by separation and ligation of right common carotid artery (CCA) and subsequently exposed to hypoxia for 2.

Transgenic barley with overexpressed PTrx increases aluminum resistance in roots during germination.

A transgenic barley line (LSY-11-1-1) with overexpressed Phalaris coerulescens thioredoxin gene (PTrx) was employed to measure the growth, protein oxidation, cell viability, and antioxidase activity in barley roots during germination on the presence of 2 mmol/L AlCl(3) on filter paper. The results show that (1) compared with the non-transgenic barley, LSY-11-1-1 had enhanced root growth, although both were seriously inhibited after AlCl(3) treatment; (2) the degree of protein oxidation and loss of cell viability in roots of LSY-11-1-1 were much less than those in roots of non-transgenic barley, as reflected by lower contents of protein carbonyl and Evans blue uptakes in LSY-11-1-1; (3) activities of catalase (CAT), glutathione peroxidase (GPX), ascorbate peroxidase (APX), and glutathione reductase (GR) in LSY-11-1-1 root tips were generally higher than those in non-transgenic barley root tips, although these antioxidase activities gave a rise to different degrees in both LSY-11-1-1 and non-transgenic barley under aluminum stress. These results indicate that overexpressing PTrx could efficiently protect barley roots from oxidative injury by increasing antioxidase activity, thereby quenching ROS caused by AlCl(3) during germination.

Hepatic angiomyolipoma: dynamic computed tomography features and clinical correlation.

Aim: To study the dynamic computed tomography (CT) features of hepatic angiomyolipoma (AML) in patients with or without tuberous sclerosis complex (TSC).

Results: Hepatic AML was prone to occur in female patients (7/10), and most of the patients (8/10) had no specific symptoms.

Protective role of exogenous nitric oxide against oxidative-stress induced by salt stress in barley (Hordeum vulgare).

To probe into the potential of relieving the oxidative damage of salt stress, we investigated the protective role of nitric oxide on barley under salt stress. Salt stress resulted in increased ion leakage, lipid peroxidation and protein oxidation in barley leaves. Simultaneous treatments of barley leaves with 50 microM sodium nitroprusside, a nitric oxide donor, alleviated the damage of salt stress, reflected by decreased ion leakage, and malendialdehyde (MDA), carbonyl, and hydrogen peroxide content in barley leaves.
