【Abstract】 Objective To investigate the effect of massage on quadriceps femoris repair and the expressions of Desmin and α-Actin in rabbits so as to explore the possible molecular mechanisms of massage in repair of muscle injury. Methods Twenty-seven New Zealand white rabbits, weighing (2.0 ± 0.5) kg, were randomly divided into 3 groups: groups A (n=3), B (n=12), and C (n=12). In group A, the rabbits were not treated as controls; in groups B and C, the rabbit models of quadriceps femoris injury were prepared by self-made beater. In group B, no massage therapy was given as nature recovery controls; in group C, RT-N2 intelligent massage device was used for massage therapy at 8 days after injury, at 3 000-3 100 r/min for 15 minutes, every day for 7 days or for 14 days. The quadriceps femoris specimens were taken from 6 rabbits of groups B and C at 14 days and 21 days, respectively. HE staining was employed to detect the histomorphological change. Immunohistochemistry staining and Western blot were used to detect Desmin and α-Actin expressions. The massage therapy effect was evaluated by the histomorphological change and Desmin and α-Actin expressions. Results All rabbits survived to the end of experiment in groups B and C. No histological change was found with regular order of muscle fibers and no connective tissue in group A; obvious tissue necrosis was seen with broken muscular fibers, muscle atrophy, and irregular order in group B; and in group C, the skeletal muscle morphology and muscle atrophy were obviously improved with regenerated muscle fibers when compared with group B. Immunohistochemistry staining showed that the Desmin and α-Actin expressions obviously reduced in groups B and C, which were significantly weaker than that in group A (P lt; 0.05); the Desmin and α-Actin expressions were significantly ber in group C than in group B (P lt; 0.05), and at 21 days than at 14 days in group C (P lt; 0.05). Western blot results showed that the Desmin and α-Actin expressions were significantly higher in group A than in groups B and C (P lt; 0.05), and the expressions were lowest at 14 days in group B. Conclusion The histomorphology and cytoskeletal structure can be significantly improved after massage, which may help to repair muscle injury by up-regulation of Desmin and α-Actin expressions.
Objective To explore the nursing effect of using Neiguan acupoint massage combined with chewing gum in patients undergoing day-case laparoscopic cholecystectomy. Methods A prospective study was conducted on patients who underwent day-case laparoscopic cholecystectomy in West China Hospital of Sichuan University between March 2023 and March 2024. The patients were randomly divided into the control group and the intervention group according to a random number table. The control group received routine care, while the intervention group received chewing gum and Neiguan acupoint massage intervention at the P6 acupoint in addition to routine care. The incidence of postoperative nausea and vomiting (PONV), pain scores, gastrointestinal function recovery time, medication use, and hospitalization related indicators were compared between the two groups of patients after surgery. Results A total of 298 patients were included. Among them, there were 163 cases in the control group and 135 cases in the intervention group. The incidence of PONV at 0.5 and 2 hours after surgery and the pain scores at 6, 12, and 24 hours after surgery in the intervention group were lower than those in the control group (P<0.05). The first bowel sounds recovery time, anal exhaust time, and eating time in the intervention group were shorter than those in the control group (P<0.05). Twenty-four hours after surgery, the usage rate of analgesic drugs (6.67% vs. 14.11%) and the usage rate of rescue antiemetic drugs (2.96% vs. 8.59%) in the intervention group were lower than those in the control group (P<0.05). There was no statistically significant difference in the delayed discharge rate or total cost between the two groups (P>0.05). The nursing satisfaction of the intervention group was higher than that of the control group (99.26% vs. 93.25%, P<0.05). Conclusions After the combination of Neiguan acupoint massage and chewing gum intervention in patients undergoingin day-case laparoscopic cholecystectomy, the PONV incidence and pain are significantly reduced, gastrointestinal functions recover faster, drug use rate is low, patient nursing satisfaction is high. This method can be promoted and applied.
ObjectiveTo establish a method for content determination of ferulic acid in Piwang massage lotion.
MethodsHigh performance liquid chromatography was used. The analysis was carried on Diamonsil C18 (150 mm×4.6 mm, 5 μm, Dimma Science and Technology Co. Ltd.) column with mobile phase consisted of methanol-2% acetic acid (32︰68). The column temperature was 30℃. The detection wavelength was 320 nm.
ResultsThe responses of ferulic acid liner in range of 4.55-91.00 μg/mL (R2=0.999 9). The average recovery of ferulic acid was 98.78% (relative standard deviation is 2.668%).
ConclusionThe method is simple, rapid and good repeatability. It can be used for quality control of Piwang massage lotion
