Objective:To explore the effect of electric acupuncture combined with Tianding acupoint on the efficacy,syndrome score,and quality of life of post-stroke intractable hiccup(IH).Methods:A total of 102 post-stroke IH patients admitted to our hospital from October 2022 to October 2023 were retrospectively included,and were divided into control group and observation group,with 51 cases in each group.The matched group patients were given conventional acupuncture treatment,while the observation group patients were given conventional electric acupuncture combined with Tianding acupoint treatment.The clinical efficacy,effectiveness,hiccup symptom scores before and Post-treatment,and quality of life score between two groups of patients.Results:The proportion of patients in the observation group who took immediate effect(27.45％vs.5.88％)and the proportion of patients who took effect within 24 hours of the first treatment(60.78％vs.17.65％)were higher than matched group.The average onset time[(32.14±9.72)h vs.(70.34±23.51)h]was significantly shorter than matched group(P＜0.05).The treatment recovery rate of observation group was higher than matched group(80.39％vs.50.98％,P＜0.05),and the total effective rate of treatment was not different from matched group(96.08％vs.86.27％,P＞0.05).Post-treatment,both groups of patients showed a significant decrease in hiccup symptom scores,and there were significant differences at different time points(P＜0.05).The hiccup symptom scores of the observation group patients at 1 d,3 d,and 5 d post-treatment were lower than matched group(P＜0.05).Post-treatment,the overall scores of appetite,mental state,sleep,and quality of life in both groups increased,and the scores in the observation group were higher than matched group(P＜0.05).Conclusion:The combination of electric acupuncture and Tianding acupoint has a significant therapeutic effect on post-stroke IH,which can quickly take effect,improve patients'clinical symptoms,and enhance their quality of life.

Objective To investigate the effects of arthroscopic modified suture-bridge surgery on shoulder stability,pain and imaging anatomical parameters of elderly patients with full-thickness rotator cuff injury.Methods A total of 104 elderly patients with full-thickness rotator cuff injury admitted to Zhuhai Hospital of Integrated Traditional Chinese and Western Medicine from September 2021 to June 2023 were selected and divided into the suture-bridge group and the modified group according to random number table method,with 52 cases in each group.Patients in the suture-bridge group underwent arthroscopic suture-bridge surgery,and patients in the modified group underwent arthroscopic modified suture-bridge surgery.Perioperative indexes,the range of motion of shoulder joint,American Shoulder and Elbow Surgeons(ASES)score,visual analogue scale(VAS)score,Constant shoulder function score,University of California Los Angeles(UCLA)shoulder score,recovery of shoulder joint,Sugaya classification of imaging before and after surgery,and the rate of complications were compared between the two groups.Results There was no significant difference in the length of incision,operation time,joint perfusion volume,intraoperative blood loss,or hospitalization time of patients between the two groups(P>0.05).The external rotation,forward flexion,and abduction ranges of motion 6 months after surgery of patients in the modified group were greater than those in the suture-bridge group(P<0.05);The ASES,Constant,and UCLA scores 6 months after surgery of patients in the modified group were higher than those in the suture-bridge group,while the VAS score was lower than that in the suture-bridge group,with statistically significant differences(P<0.05);The proportions of patients who experienced complete painlessness in shoulder joint,had the same range of motion as the healthy side,and recovered to work ability before surgery 6 months after surgery in the modified group were higher than those in the suture-bridge group,and the Sugaya classification of imaging in the modified group was better than that in the suture-bridge group,with statistically significant differences(P<0.05);There was no significant difference in the incidence of shoulder joint swelling,limb numbness,bleeding,or retear of patients between the two groups(P>0.05).Conclusion Arthroscopic modified suture-bridge surgery for elderly patients with full-thickness rotator cuff injury can relieve postoperative pain,improve shoulder joint function,expand range of motion of shoulder joint,and improve imaging anatomical parameters without increasing the rate of complications.
