Tuina is a treatment method in traditional Chinese medicine which has analgesic effects and effectively alleviates the symptoms of neuropathic pain (NP). Transient receptor potential vanilloid type 1 (TRPV1) and transient receptor potential ankyrin type 1 (TRPA1) play major roles in transmitting nociceptive sensory signals in the nociceptive primary sensory dorsal root ganglion (DRG) nerve. The nitric oxide (NO)/cyclic guanosine 3',5'-monophosphate(cGMP) pathway exerts both nociceptive and antinociceptive effects in various chronic pain models. ⋯ Similarly, the expression of TRPV1, TRPA1, NO, soluble guanylate cyclase β (sGCβ), cGMP, and PKG1 was significantly decreased in the DRG of the tuina and tuina + TRPV1/TRPA1 antagonist group was significantly decreased. These findings suggest that the tuina intervention can effectively improve the symptoms of thermal and mechanical allodynia caused by peripheral nerve injuries. Tuina exerts immediate analgesic effects through the TRPV1/TRPA1-NO-cGMP-PKG signaling pathway.

Review Meta Analysis Comparative Study
Comparison of Safety and Efficacy of Anesthesia Methods in Percutaneous Endoscopic Lumbar Discectomy: A Network Meta-Analysis.
Background: The objective of this study was to systematically evaluate the safety and efficacy of local anesthesia, general anesthesia, and epidural anesthesia in percutaneous endoscopic lumbar discectomy (PELD). Methods: We searched PubMed, EMBASE, and OVID databases for all relevant studies. All statistical analysis was performed using STATA 17.0. ⋯ Epidural anesthesia is most advantageous in anesthesia satisfaction and postoperative VAS scores. General anesthesia is most advantageous in postoperative ODI. In the future, more multicenter RCTs are needed to further compare the safety and effectiveness of different anesthesia methods in PELD.

Meta Analysis
The Causal Relationship between Angina Pectoris and Gout Based on Two Sample Mendelian Randomization.
Two-sample Mendelian randomization (MR) was conducted to assess the causal relationship between angina pectoris and gout. Material and Methods. Based on genome-wide association studies, single nucleotide polymorphisms (SNPs) that were closely associated with gout were selected from the UK Biobank-Neale Lab (ukb-a-107) as genetic instrumental variables. Considering that gout is characterized by elevated blood uric acid levels, SNPs related to blood uric acid levels were screened from BioBank Japan (bbj-a-57) as auxiliary gene instrumental variables. SNPs closely associated with angina pectoris onset were screened from the FINN dataset (finn-b-I9_ANGINA) as outcome variables. Two-sample MR was conducted, with inverse variance weighting (IVW) of the random effects model as the primary result, along with the weighted median method (WME) and the MR-Egger regression method. To further confirm the causal relationship between angina and gout incidence, a meta-analysis was conducted on the IVW results of the ukb-a-107 and bbj-a-57. ⋯ This MR study found a clear causal relationship between angina pectoris and gout, which increases the risk of angina pectoris.

Randomized Controlled Trial
Continuous Intra-Incisional Bupivacaine for Postoperative Analgesia after Hip Nailing Surgery: A Randomized Clinical Trial.
The effectiveness of continuous wound infiltration (CWI) as a postoperative pain-control technique has been shown in many surgical procedures. This study investigates the effect of CWI of local anesthetic on postoperative pain control in intertrochanteric fracture patients undergoing hip nailing surgery. ⋯ CWI of bupivacaine helps better pain reduction during the early postoperative hours while it reduces opioid consumption, minimizes nausea and vomiting, and improves patient satisfaction.

Randomized Controlled Trial
Transcutaneous Electrical Nerve Stimulation Integrated into Pants for the Relief of Postoperative Pain in Hip Surgery Patients: A Randomized Trial.
The effect of transcutaneous electrical nerve stimulation (TENS) on pain and impression of change was assessed during a 2.5-hour intervention on the first postoperative days following hip surgery in a randomized, single-blinded, placebo-controlled trial involving 30 patients. ⋯ Mixed-frequency TENS integrated in pants could potentially be an interesting addition to the arsenal of treatments for multimodal analgesia following hip surgery. This trial is registered with NCT05678101.
