Comparison of the Efficacy of Nonsteroidal Anti-Inflammatory Drugs and Opioids in the Treatment of Acute Renal Colic: A Systematic Review and Meta-Analysis

Wrist-ankle acupuncture combined with pain nursing for the treatment of urinary calculi with acute pain

BACKGROUND

Urological calculi often cause renal colic, which is characterized by paroxysmal or persistent severe pain in the upper abdomen or lumbar region. Development of methods to quickly relieve these pain symptoms has garnered clinical attention. Wrist-ankle acupuncture is a type of floating acupuncture therapy administered at selected points in the carpal and ankle areas, and it has good pain-relieving effects. We used wrist-ankle acupuncture combined with pain nursing for pain intervention in patients with renal calculi to confirm its application and safety.

AIM

To study the effect of wrist-ankle acupuncture combined with pain nursing in the treatment of urinary calculi with acute pain.

METHODS

Eighty-two patients with urinary calculi with acute pain as the first symptom followed at our hospital from November 2019 to June 2021 were enrolled in the study and classified into two groups according to the odd and even numbers of the visit sequences, each with 41 cases. The control group received a routine nursing intervention and intramuscular injection of nonsteroidal anti-inflammatory drugs, whereas the observation group received pain management nursing and wrist-ankle acupuncture. Subsequently, the pain-relieving effect was compared between the two groups.

RESULTS

The score on the visual analog scale (VAS) at 24, 48, and 72 h postintervention was decreased in both groups compared with the baseline data; moreover, the observation group scored significantly lower than the control group on the VAS at each time point after the intervention (P < 0.05). The clinical efficacy at 24 h postintervention was not significantly different between the two groups (P > 0.05). In turn, the pain recurrence rate at 72 h postintervention was lower in the observation group compared with the control group (P < 0.05). Finally, the nursing satisfaction rate in the observation group was significantly higher than that observed in the control group (P < 0.05). No serious adverse reactions occurred during the treatment and the safety of treatment was high in both groups.

CONCLUSION

Wrist-ankle acupuncture combined with pain nursing for treating urolithiasis with acute pain effectively alleviated the degree of pain and reduced the recurrence rate, which was worthy of clinical application.

Removal of Non-Steroidal Anti-Inflammatory Drugs from Drinking Water Sources by GO-SWCNT Buckypapers

Pharmaceutical products such as antibiotics, analgesics, steroids, and non-steroidal anti-inflammatory drugs (NSAIDs) are new emerging pollutants, often present in wastewater, potentially able to contaminate drinking water resources. Adsorption is considered the cheapest and most effective technique for the removal of pollutants from water, and, recently, membranes obtained by wet filtration method of SWCNT aqueous solutions (SWCNT buckypapers, SWCNT BPs) have been proposed as self-standing porous adsorbents. In this paper, the ability of graphene oxide/single-walled carbon nanotube composite membranes (GO-SWCNT BPs) to remove some important NSAIDs, namely Diclofenac, Ketoprofen, and Naproxen, was investigated at different pH conditions (pH 4, 6, and 8), graphene oxide amount (0, 20, 40, 60, and 75 wt.%), and initial NSAIDs concentration (1, 10, and 50 ppm). For the same experimental conditions, the adsorption capacities were found to strongly depend on the graphene oxide content. The best results were obtained for 75 wt.% graphene oxide with an adsorption capacity of 118 ± 2 mg g^-1 for Diclofenac, 116 ± 2 mg g^-1 for Ketoprofen, and 126 ± 3 mg g^-1 for Naproxen at pH 4. Overall, the reported data suggest that GO-SWCNT BPs can represent a promising tool for a cheap and fast removal of NSAIDs from drinking water resources, with easy recovery and reusability features.

One-step fabrication of lidocaine/CalliSpheres® composites for painless transcatheter arterial embolization

BACKGROUND

Transcatheter arterial embolization (TAE) is one of the first-line treatments for advanced hepatocellular cancer. The pain caused by TAE is a stark complication, which remains to be prevented by biomedical engineering methods.

METHODS

Herein, a commercial embolic agent CalliSpheres^® bead (CB) was functionally modified with lidocaine (Lid) using an electrostatic self-assembly technique. The products were coded as CB/Lid-n (n = 0, 5, 10, corresponding to the relative content of Lid). The chemical compositions, morphology, drug-loading, and drug-releasing ability of CB/Lid-n were comprehensively investigated. The biocompatibility was determined by hemolysis assay, live/dead cell staining assay, CCK8 assay, immunofluorescence (IHC) staining assay and quantitative real-time PCR. The thermal withdrawal latency (TWL) and edema ratio (ER) were performed to evaluate the analgesia of CB/Lid-n using a plantar inflammation model. A series of histological staining, including immunohistochemistry (IL-6, IL-10, TGF-β and Navi1.7) and TUNEL were conducted to reveal the underlying mechanism of anti-tumor effect of CB/Lid-n on a VX2-tumor bearing model.

RESULTS

Lid was successfully loaded onto the surface of CalliSpheres^® bead, and the average diameter of CalliSpheres^® bead increased along with the dosage of Lid. CB/Lid-n exhibited desirable drug-loading ratio, drug-embedding ratio, and sustained drug-release capability. CB/Lid-n had mild toxicity towards L929 cells, while triggered no obvious hemolysis. Furthermore, CB/Lid-n could improve the carrageenan-induced inflammation response micro-environment in vivo and in vitro. We found that CB/Lid-10 could selectively kill tumor by blocking blood supply, inhibiting cell proliferation, and promoting cell apoptosis. CB/Lid-10 could also release Lid to relieve post-operative pain, mainly by remodeling the harsh inflammation micro-environment (IME).

CONCLUSIONS

In summary, CB/Lid-10 has relatively good biocompatibility and bioactivity, and it can serve as a promising candidate for painless transcatheter arterial embolization.
