Integrated UHPLC-MS/MS and 16S rRNA sequencing reveals that Weiling Decoction alleviates spleen deficiency with dampness pattern diarrhea by modulating intestinal microbiota.
VIP (Vasoactive Intestinal Polypeptide) · 3 Biotech · 2023 · Observational · Preclinical
Weiling Decoction may modulate intestinal microbiota and affect gastrointestinal functions in a rodent model of SDDP diarrhea, but the clinical relevance of these findings remains uncertain.
WLD reduced serum vasoactive intestinal peptide (VIP) levels, p<0.05.

Safety and efficacy of Meridian sinew tuina (MST) for post-surgical upper limb lymphedema: a systematic review and meta-analysis.
VIP (Vasoactive Intestinal Polypeptide) · Journal of obstetrics and gynaecology : the journal of the Institute of Obstetrics and Gynaecology · 2026 · Meta-analysis · n=1114
MST shows promise in reducing upper limb swelling and improving symptoms in patients with breast cancer-related lymphedema, but should not be unconditionally recommended due to potential biases.
SMD = 1.59; 95% CI: 1.44 to 1.74; Z = 20.81; p < 0.0001; N = 924.

Machine learning-guided spectral fingerprinting reveals Parkinson's disease-associated biochemical changes in Drosophila melanogaster.
VIP (Vasoactive Intestinal Polypeptide) · Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy · 2026 · Observational
FT-IR spectroscopy may provide a rapid method to characterize biochemical changes in Parkinson's disease models, but findings from Drosophila may not directly apply to humans.
Not reported in abstract.

Accuracy and feasibility of robot-assisted implant surgery in edentulous patients: A retrospective case series.
VIP (Vasoactive Intestinal Polypeptide) · Journal of dentistry · 2026 · Observational · n=15
Robot-assisted implant surgery in edentulous patients showed high accuracy and a 100% implant survival rate, but further randomized controlled trials are needed to confirm these results.
Mean linear deviations were 0.71 ± 0.23 mm at the implant neck and 0.74 ± 0.24 mm at the apex.

Expression and Correlation Analysis of Neuropeptide Family Members in the Peripheral Blood of Patients with COVID-19.
VIP (Vasoactive Intestinal Polypeptide) · Current pediatric reviews · 2026 · Observational
ASCL1 levels are lower in children with COVID-19 compared to those with non-COVID-19 bronchial pneumonia, and it correlates negatively with inflammation markers like neutrophils and CRP.
ACE2 in non-COVID-19 and moderate COVID-19 groups was higher than that in severe groups (p=0.04; p=0.03, respectively).
C

Epilepsy and premature mortality driven by inhibitory neuron dysfunction in a mouse model of <i>SCN1A</i> gain-of-function neurodevelopmental disorder
VIP (Vasoactive Intestinal Polypeptide) · biorxiv-preprint · 2026 · Animal study · Preclinical
This study demonstrates that SCN1A gain-of-function mutations can lead to severe epilepsy and premature mortality in mice, with potential lifespan extension observed following treatment with GS967.
100% premature mortality in 64/64 mutant mice between postnatal day 12-18.
C
