Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective: The effect on fat infiltration (FI) of paraspinal muscles in degenerative lumbar spinal diseases has been demonstrated except for spinopelvic parameters. The present study is to identify the effect of spinopelvic parameters on FI of paraspinal muscle (PSM) and psoas major muscle (PMM) in patients with degenerative lumbar spondylolisthesis. Methods: A single-center, retrospective cross-sectional study of 160 patients with degenerative lumbar spondylolisthesis (DLS) and lumbar stenosis (LSS) who had lateral full-spine x-ray and lumbar spine magnetic resonance imaging was conducted. PSM and PMM FIs were defined as the ratio of fat to its muscle cross-sectional area. The FIs were compared among patients with different pelvic tilt (PT) and pelvic incidence (PI), respectively. Results: The PSM FI correlated significantly with pelvic parameters in DLS patients, but not in LSS patients. The PSM FI in pelvic retroversion (PT > 25°) was 0.54 ± 0.13, which was significantly higher in DLS patients than in normal pelvis (0.41 ± 0.14) and pelvic anteversion (PT < 5°) (0.34 ± 0.12). The PSM FI of DLS patients with large PI ( > 60°) was 0.50 ± 0.13, which was higher than those with small ( < 45°) and normal PI (0.37 ± 0.11 and 0.36 ± 0.13). However, the PSM FI of LSS patients didn’t change significantly with PT or PI. Moreover, the PMM FI was about 0.10–0.15, which was significantly lower than the PSM FI, and changed with PT and PI in a similar way of PSM FI with much less in magnitude. Conclusion FI of the PSMs increased with greater pelvic retroversion or larger pelvic incidence in DLS patients, but not in LSS patients.

It has gradually become a consensus in the industry that the traditional Chinese medicine gypsum should be decocted first, but the understanding of decocting method is not completely unified in the works of doctors since ancient times, and there are occasional disputes about whether it is necessary to decocting first. In this study, the phase determination, physical and chemical characterization, qualitative and quantitative analysis of inorganic and organic components of the decoctions of herbal pairs and the whole prescription Maxingshigan decoction with gypsum as the center, and the pre-decoctions and co-decoctions of them were carried out to explore the scientific connotation of the pre-decoctions of gypsum. Results show that decoction phases were different between the co-decoctions and pre-decoctions of licorice-gypsum (Gancao-Shigao, GC-SG), ephedra-gypsum (Mahuang-Shigao, MH-SG) and almond-gypsum (Xingren-Shigao, XR-SG). The results of the micromorphology, particle size and zeta potential of herbal pairs and prescription (Quanfang, QF) showed that the supramolecular particles in pre-decoctions were smaller, more uniform and more stable than the co-decoctions. The results of organic components analysis showed that different cooking methods did not change the organic composition and content. ICP-OES results showed that the content of inorganic components in pre-decoctions was higher than in co-decoctions for the same boiling time of gypsum. The IR results showed that the pre-decoctions had stronger chemical functional group effect than the co-decoctions. To sum up, compared with the co-decoction, the pre-decoction of gypsum has different phase state and chemical composition interaction, and the difference of inorganic composition is an important material basis affecting the change of phase state compared with the co-decoction. It indicates that the material basis of traditional Chinese medicine decoction is indeed different whether gypsum is decocted first or not, which can provide a basis for the clinical application of decocted gypsum.

Licorice-gypsum (gancao-shigao, GC-SG) drug pair was used as the research object, using supramolecular chemistry to explore the scientific connotation of combining herbal medicine GC with insoluble mineral medicine SG in clinical application of traditional Chinese medicine. ① The Tyndall effect, microscopic morphology and particle size of the single and co-decocted of GC and SG were observed, the paste content and conductivity were determined, and the interaction between GC and SG was detected by isothermal titration calorimetry (ITC) and infrared absorption spectroscopy (IR). ② Calcium chloride (CaCl₂), a soluble calcium salt of equal gypsum quality, was used instead of SG with GC for co-decocting to explore the effect of calcium salt content on the water decocting, and the characteristics were combined with the Tyndall effect, microscopic morphology, paste content and conductivity. ITC and IR techniques were used to detect the interaction between the two, and the interaction between them was detected by ITC and IR. The zeta potential and ultraviolet-visible spectrophotometry (UV-vis) of GC-SG and GC-CaCl₂ co-decoction were compared, and the inorganic and organic components in the co-decoction were detected by inductively coupled plasma optical emission spectrometer (ICP-OES) and high performance liquid chromatography (HPLC). The results showed: ① Compared with the liquid phase of single decoction, GC-SG co-decoction had more obvious Tyndall effect, and showed uniform spherical nanoparticles under electron microscope. Physical characterization results such as paste content and conductivity showed that co-decoction promoted the dissolution of each other's components; ITC and IR results showed that there was strong interaction between GC and SG, which preliminatively indicated that GC and SG co-decoction promoted the formation of uniform and stable supramolecular system of traditional Chinese medicine. ② When soluble calcium salt was used to substitute insoluble SG with GC for co-decocting, a stronger but astigmatic light path appeared than single decocting solution, the zeta potential was reduced, and a large number of accumulated polymers were formed. The results of paste content and conductivity showed that the dissolution of the co-decocting component was reduced than the single decocting component. ITC, UV-vis and IR results showed that there was interaction between GC with Ca²⁺ and SG. The formation of polysink indicated that a large amount of soluble calcium salt would destroy the stability of supramolecular Chinese medicine. The results of ICP-OES and HPLC showed that the glycyrrhizic acid (GA) content of the former lower than the latter, which was related to the formation of a large number of polycondensates with the increase of Ca²⁺ concentration and the decrease of the dissolution of GA and other active ingredients. This study indicates that the compatibility of GC and SG can form a uniform and stable supramolecular system of traditional Chinese medicine. Calcium salt, the main component of SG, is taken as the starting point. Excessive soluble Ca²⁺ can promote the aggregation of active ingredients such as GA, so as to reveal the scientific connotation of the compatibility of GC and SG, an insoluble mineral medicine.
