Objective:To investigate the efficacy of pelvic floor neuromuscular stimulation combined with progesterone in the treatment of pelvic floor function recovery after hysterectomy.Methods:This study used a randomized controlled design, involving 108 patients with pelvic floor dysfunction who underwent hysterectomy at Shaanxi Provincial People's Hospital between January 2021 and December 2023. These patients were randomly assigned to either a control group or an observation group, with 54 patients in each group, using a random number table for allocation. Both groups received basic pelvic floor muscle training. The control group was treated solely with progesterone vaginal soft capsules, while the observation group also received neuromuscular stimulation through pelvic rehabilitation equipment. Before and after treatment, changes in muscle strength (measured by electromyography values of type I and type II muscle fibers), quality of life (assessed using the Pelvic Floor Dysfunction Index Questionnaire-7 and the Pelvic Floor Distress Inventory-Short Form 20), pelvic relaxation indicators (levels of laminin, relaxin, and transforming growth factor beta-3), and Pelvic Organ Prolapse Quantification staging were compared between the two groups. Additionally, stress urinary incontinence, lumbosacral pain, sexual satisfaction, vaginal prolapse conditions, and overall efficacy post-treatment were compared between the two groups.Results:After treatment, electromyography values for type I and type II muscle fibers in the observation group were (4.71 ± 0.61) μA and (5.63 ± 0.79) μA, respectively, which were significantly higher than those in the control group [(3.51 ± 0.53) μA, (4.53 ± 0.50) μA, t = -10.91, -8.65, both P < 0.001]. The scores for the Pelvic Floor Dysfunction Index Questionnaire-7 and Pelvic Floor Distress Inventory-Short Form 20 in the observation group were (4.56 ± 0.64) and (4.56 ± 0.64), respectively, both of which were significantly lower than those in the control group [(5.36 ± 0.70), (5.36 ± 0.70), t = 6.20, 26.74, both P < 0.001]. The levels of laminin, relaxin, and transforming growth factor beta-3 in the observation group were (27.28 ± 3.00) μg/L, (53.32 ± 6.40) μg/L, and (28.25 ± 3.67) mg/L, respectively, all of which were significantly lower than those in the control group [(32.14 ± 3.54) μg/L, (59.22 ± 6.51) μg/L, (36.25 ± 3.99) mg/L, t = 7.70, 4.75, 10.84, all P < 0.001]. The proportion of patients in the observation group with a POP-Q stage of 0 was 90.74% (49/54), which was significantly higher than that in the control group [68.52% (37/54), χ2=8.22, P < 0.05]. The proportion in the observation group with a stage of 1 was 7.41% (4/54), which was significantly lower than that in the control group [25.93% (14/54), χ2 = 6.67, P < 0.05]. The incidence rates of stress urinary incontinence, lumbosacral pain, sexual dissatisfaction, and vaginal prolapse in the observation group were all significantly lower than those in the control group ( χ2 = 4.41, 4.36, 4.70, 4.41, all P < 0.05). The overall effective rate in the observation group was 92.59% (50/54), which was significantly higher than that in the control group [74.07% (40/54), χ2 = 6.67, P < 0.05]. Conclusions:Pelvic floor neuromuscular stimulation combined with progesterone vaginal soft capsules can improve muscle strength in patients with pelvic floor dysfunction after hysterectomy, enhance life satisfaction, relieve pelvic relaxation, and promote comprehensive recovery of pelvic function.

OBJECTIVE To explore the improvement effect and mechanism of petroleum ether extract of Saposhnikovia divaricata on rheumatoid arthritis (RA) rats by regulating neutrophil extracellular traps (NETs). METHODS Establishment of rat RA model using bovine type Ⅱ collagen and Freund’s complete adjuvant. The model rats were randomly divided into model group and low-dose, middle-dose and high-dose groups (55, 110, 220 mg/kg) of petroleum ether extract of S. divaricata; the normal group without modeling was also established, with 10 rats in each group. Each group was given corresponding drugs or constant volume of 2% Tween-80 solution intragastrically, once a day, for consecutive 28 days. The toe swelling degree in rats was observed, and the arthritis index (AI) was scored. The serum levels of interleukin-1β (IL-1β), IL-10, IL-17, tumor necrosis factor-α (TNF-α), 25-hydroxyvitamin D3 [25(OH)D3], myeloperoxidase (MPO), neutrophil elastase (NE) and NETs in rats were detected. The histopathological changes in ankle joint were observed. The expression of citrullinated histone H3 (CitH3) in ankle joint as well as the expressions of cytochrome P450 24A1 (CYP24A1), cytochrome P450 27B1 (CYP27B1),vitamin D receptor (VDR) and peptidyl arginine deiminase 4 疾病。E-mail:zhongyao626@126.com (PAD4) in synovium were all determined. RESULTS Compared with the model group, the toe swelling degree and AI score in the middle-dose and high-dose groups of petroleum ether extract of S. divaricata decreased significantly from day 14 to day 28 after administration (P<0.05 or P<0.01). The serum levels of IL-1β, IL-17, TNF-α, MPO, NE and NETs decreased significantly, while the levels of IL-10 and 25(OH)D3 increased significantly (P<0.05 or P<0.01). The widened ankle joint space and the improved structure were found; the expression of CitH3 in ankle joint, and the expressions of CYP24A1 and PAD4 in synovium were down-regulated significantly, while the expressions of CYP27B1 and VDR were up-regulated significantly in synovium (P<0.05 or P<0.01). CONCLUSIONS The petroleum ether extract of S. divaricata may inhibit the production of NETs and improve the symptoms of RA by regulating the vitamin D system.
