Effects Of Heat-Conduction Dry Needling Therapy On TRPV1 Channel In Rats.
Article in Journal of pain research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study was aimed to investigate the effects of heat-conduction dry needling therapy on chronic myofascial pain syndrome (CMPS) in rats and explore the analgesic mechanisms by measuring the mRNA expression of transient receptor potential cation channel subfamily V member 1 (TRPV1) in musculus gastrocnemius.
methodsSeventy-two rats were randomly divided into five groups. Group A was the control group containing eight normal rats. Group B was the model group where 16 rats developed CMPS in musculus gastrocnemius but received no treatments. Groups C, D, and E containing 16 CMPS rats in each group were the trial groups receiving heat-conduction dry needling therapy. In detail, rats in Group C received dry needling treatment at the heating temperature of 44°C. Rats in Group D received intramuscular injection of capsazepine before receiving dry needling treatment with the heating temperature at 44°C. Rats in Group E received dry needling treatment with the heating temperature at 40°C. The mRNA expression of TRPV1, protein kinase C (PKC), and interleukin (IL)-6 in the needle insertion points of musculus gastrocnemius was measured at 24 hrs and 7 days after dry needling therapy.
resultsCompared with untreated CMPS rats, the mRNA expression of TRPV1, PKC, and interleukin-6 (IL-6) was increased in rats receiving dry needling therapy with the heating temperature at 44°C for 24 hrs. However, the mRNA expression of TRPV1, PKC, and IL-6 in CMPS rats receiving injection of TRPV1 antagonist capsazepine into musculus gastrocnemius followed by temperature-needling at 44°C was analogous to that in untreated CMPS rats.
conclusionDry needling therapy with needles heated to 44°C could impact the activity of TRPV1/PKC/IL-6 pathway.
