Objective To investigate the therapeutic efficacy of the combination of upper limb rehabilitation robots(ULRR)and ultrasound-guided extracorporeal shock wave(ESW)in the treatment of mild to moderate rotator cuff injuries.Methods A total of 90 patients with mild to moderate rotator cuff injuries,who were admitted to the Second Affiliated Hospital of Anhui Medical University between January 2023 and March 2024,were selected and randomly assigned to three groups:Group A(basic rehabilitation),Group B(basic rehabilitation+ESW),and Group C(basic rehabilitation+ESW+ULRR),with 30 patients in each group.Before and after treatment,shoulder pain was assessed using the visual analogue scale(VAS).Proprioception was evaluated based on shoulder joint position reproduction error.The integral electromyography(iEMG)and root mean square(RMS)values of the median tract,supraspinatus,infraspinatus,and deltoid muscles on the affected side were measured using surface electromyography(sEMG).The active range of motion(AROM)for external rotation,abduction,and forward flexion of the affected shoulder was measured using a standard goniometer.Overall shoulder function was evaluated using the Constant-Murley Shoulder Score(CMS).The clinical efficacy rate and patient satisfaction levels were compared among the three groups.Results After treatment,the VAS score and shoulder position reproduction deviation angle in all three groups significantly decreased.Additionally,the iEMG and RMS values of the middle deltoid,supraspinatus,and infraspinatus muscles;the AROM of shoulder external rotation,abduction,and forward flexion;and the CMS scores(including pain,activities of daily living,active range of motion,and muscle strength)all showed significant improvement.Furthermore,the degree of improvement in all evaluated parameters in Group C was significantly greater than that observed in Groups A and B(P<0.05).Moreover,Group C demon-strated a significantly higher clinical response rate and greater patient satisfaction compared to Groups A and B(P<0.05).Conclusion For patients with mild to moderate rotator cuff injuries,the integration of an upper limb rehabilitation robot with extracorporeal shock wave therapy demonstrates superior therapeutic outcomes,effectively alleviating pain,enhancing motor function and proprioception,and increasing overall patient satisfaction.

Objective:To observe the effect of peripheral 5-hydroxytryptophan (5-HT)-induced neutrophil extracellular trap (NET) on lung injury in septic mice.Methods:Wild-type (WT type) and Tph1 knockout (KO) C57 mice (6-8 weeks) were selected and divided into WT mice sham group, WT mice sepsis group, Tph1 KO mice sham group and Tph1 KO mice sepsis group according to the random number table method. Mice in the sham group received sham surgery (only open the abdominal cavity to flip the cecum without ligation and puncture, and then close the abdominal cavity); the mice in the sepsis group received cecal ligation and puncture (CLP) to establish sepsis model. The mice were sacrificed 12 hours after the operation, and the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in bronchialalveolar lavage fluid (BALF) were detected by enzyme linked immunoadsordent assay (ELISA); at the same time, the lung tissues were collected, and the pathological changes of lung tissues were observed under light microscope, and the production of NET in lung tissues was observed by immunofluorescence microscope. Results:The pathological results suggested that the lung tissue structure in sham groups was intact without exudation, while the alveolar structures of mice in the sepsis groups were damaged, with obvious exudation in the alveolar cavity and thickened alveolar walls accompanied by a large number of inflammatory cell infiltration, and the degree of lung injury in the sepsis group of WT mice was more severe than that of the sepsis group of Tph1 KO mice. ELISA results showed that there was no statistically significant difference in the contents of TNF-α and IL-6 in mice BALF from different strains of the sham group; while the contents of TNF-α and IL-6 in BALF of septic mice group were significantly higher than those in sham group [WT mice: TNF-α (μg/L) was 158.20±28.46 vs. 14.00±3.28, IL-6 (μg/L) was 304.98±21.78 vs. 57.70±12.30; Tph1 KO mice: TNF-α (μg/L) was 85.88±20.13 vs. 14.95±1.53, IL-6 (μg/L) was 169.50±45.61 vs. 55.05±12.68, all P < 0.01], and the above index levels in the sepsis group of WT mice were significantly higher than the sepsis group of Tph1 KO mice [TNF-α (μg/L): 158.20±28.46 vs. 85.88±20.13, IL-6 (μg/L): 304.98±21.78 vs. 169.50±45.61, both P < 0.01]. Immunofluorescence staining showed that a very small amount of NET formation was detected in the mice lungs from the sham group; a large amount of NET formation was detected in the lung tissues in the sepsis group, which were significantly higher than those in sham group [WT mice: (34.75±7.27)% vs. (1.75±0.96)%, Tph1 KO mice: (14.25±5.74)% vs. (2.50±1.29)%, both P < 0.01], and the amount of NET produced in the lung tissues of the WT mice sepsis group was significantly higher than that of the Tph1 KO mice sepsis group [(34.75±7.27)% vs. (14.25±5.74)%, P < 0.01]. Conclusions:In sepsis, the increased production of inflammatory factors in the mice lung tissues induces to lung injury. The mechanism may relate to the increased production of NET in the lung tissues mediated by peripheral 5-HT synthesized by enterochromaffin cells and released into the blood; inhibiting the production of 5-HT in the peripheral blood can effectively reduce the production of NET in the lung tissues, thereby reducing lung injury.
