The Tibetan Plateau, known as the "Asian water tower," is a hotspot for complex hydroclimatic changes. We reveal that the previously decreasing atmospheric evaporative demand ( ) trend at the end of the 20 century has reversed over the last two decades. Although both wind stilling and solar dimming have persisted, their effects on rates have been overshadowed by increasing air temperatures and decreasing relative humidity, leading to a net rise in for 1980-2015.

Background: Allopregnanolone is a kind of neuroactive steroid or neurosteroid in the central nervous system that acts as an endogenenous GABA receptor positive modulator. However, at present, no comprehensive bibliometric analysis regarding allopregnanolone research is available. In our study, we intend to analyze the research trends and hot spots related to allopregnanolone in the past 20 years.

Transient receptor potential vanilloid 1 (TRPV1) is a well‑documented nociceptor. Notably, Hsc70 can inhibit TRPV1 expression and function, suggesting that Hsc70 may have pain regulation potential.

Sensory neuronal hypersensitivity in the dorsal root ganglion (DRG) is essential for the onset and maintenance of chronic pain. Satellite glial cells (SGCs) in the DRG potentially affect the function of sensory neurons, possibly by mediating extracellular or paracrine signaling.

Three-quarters of human infections are caused by serotype 2. A retrospective analysis of human cases in Shenzhen, a megacity in China, with high pork consumption, between 2005 and 2021 was conducted to understand its genomic epidemiology, pathogen virulence, and drug resistance characteristics.

The tourism industry has undergone rapid inquiry in modern times. Based on climatic importance, current research intends to inquire about the role of green financing in enhancing tourism growth by mitigating carbon emissions in China. The study used Data Envelopment Analysis to infer the efficiency of the study model in the study context based on research topicality.

We performed a meta-analysis to evaluate the effect of additional AS in patients with NSCLC taking TKIs.
Methods: Relevant observational studies were identified by a search of Medline, Embase, and Web of Science databases.
A significant decrease in the expression of spinal microRNA‑29c (miR‑29c), which is responsible for the regulation of oxytocin receptor (OXTR) expression, was observed in nerve injury pain during childbirth. The present study investigates whether spinal miR‑29c could be a potential target for the treatment of pain, via the oxytocin (OT)‑γ‑aminobutyric acid (GABA) pathway. A spared nerve injury (SNI) rat model was established to induce neuropathic pain, simulating hyperalgesia.

Epidural analgesia (EA) has a well-known analgesic effect and is commonly used during labor. This review summarized frequently encountered and controversial problems surrounding EA during labor, including the labor process and maternal intrapartum fever, to build knowledge in this area.

Intermittent bolus is a widely used administration paradigm for vasopressors in obstetric anesthesia in China. Thus, in this randomized, double-blinded study, we compared the efficacy and safety of equivalent bolus norepinephrine and phenylephrine for rescuing maternal post-spinal hypotension.
View Article and Find Full Text PDFBackground: Studies have shown the efficacy of norepinephrine in the treatment of maternal hypotension during cesarean section by comparing it to treatment with phenylephrine. However, few studies have compared the efficacy of norepinephrine to ephedrine.
Methods: Ninety-seven women undergoing elective cesarean section were administered norepinephrine at 4 μg/minute (group N; n = 48) or ephedrine at 4 mg/minute (group E; n = 49) immediately postspinal anesthesia, with an on-off titration to maintain systolic blood pressure (SBP) at 80% to 120% of baseline.
BACKGROUND The pathogenesis of chemotherapy-induced neuropathy, a dose-dependent adverse effect of cisplatin, involves mitochondrial dysfunction. PTEN-induced putative kinase 1 (PINK1)/Parkin-mediated mitophagy removes damaged mitochondria under various pathological conditions. The objective of this study was to determine mitophagy status and its effects on mitochondrial function and neuronal cell damage after cisplatin treatment using an in vitro model of cisplatin-induced neurotoxicity.

In this study, we explored the expression profiles of long noncoding RNAs (lncRNAs) and mRNAs, along with their biological function and regulatory network, in mice after repeated social defeat (RSD) stress to explore their potential involvement in the development of anxiety-like behaviors.
Main Methods: RNA-sequencing was used to screen all differentially expressed (DE) lncRNAs and mRNAs between the RSD and control groups.
Neuropathic pain developing after peripheral or central nerve injury is the result of pathological changes generated through complex mechanisms. Disruption in the homeostasis of excitatory and inhibitory neurons within the central nervous system is a crucial factor in the formation of hyperalgesia or allodynia occurring with neuropathic pain. The central GABAergic pathway has received attention for its extensive distribution and function in neural circuits, including the generation and development of neuropathic pain.

MATERIAL AND METHODS One hundred and sixty-six parturient women with preeclampsia who had a baseline systolic blood pressure (SBP) <80% during spinal anesthesia for cesarean section were divided into three treatment groups; bolus norepinephrine 4 μg (group N) (n=56), phenylephrine 50 μg (group P) (n=55), and ephedrine 4 mg (group E) (n=55). Primary outcomes included overall SBP and heart rate (HR) until delivery.

Since 2015, various studies have explored the use of norepinephrine to manage maternal hypotension. We conducted this systematic review and meta-analysis of available randomized controlled trials (RCTs) to compare the efficacy and safety of norepinephrine and phenylephrine for the prevention and treatment of maternal hypotension.
View Article and Find Full Text PDFMaternal hypotension commonly occurs during spinal anesthesia for cesarean delivery, with a decrease of systemic vascular resistance recognized as a significant contributor. Accordingly, counteracting this effect with a vasopressor that constricts arterial vessels is appropriate, and the pure -adrenergic receptor agonist phenylephrine is the current gold standard for treatment. However, phenylephrine is associated with dose-dependent reflex bradycardia and decreased cardiac output, which can endanger the mother and fetus in certain circumstances.

Mounting preclinical and clinical studies have shown neuropathic pain is highly associated with histone acetylation modification, which follows expression regulation of various pain-related molecules such as mGluR1/5, glutamate aspartate transporter, glutamate transporter-1, GAD65, Na1.8, Kv4.

We herein propose that the proinflammatory cytokine MIF participates in the regulation of neuropathic hypersensitivity by interacting with and suppressing the descending dopaminergic system. The lumbar spinal cord (L-SC) and ventral tegmental area (VTA) are two major locations with significant upregulation of MIF after chronic constriction injury (CCI) of the sciatic nerve, and they display time-dependent changes, along with a behavioral trajectory.
