Coronary heart disease (CHD) is a frequently-occurring cardiovascular disease in the clinical setting with high mortality rate.Negative emotions, such as anxiety and depression, are common in patients with CHD. These negative emotions predict a worse prognosis and rehabilitation outcome and impair the patients' quality of life. Cardiac rehabilitation can improve the emotion of anxiety and depression effectively and provide superior benefits in quality of life in CHD patients.

Objective To observe the surgical results of modified percutaneous endoscopic interlaminar decompression(PEID) and traditional PEID in the treatment of degenerative lumbar spinal stenosis (DLSS),and to explore the optimizations scheme of PEID for DLSS.Methods 60 patients (36 males and 24 females) were brought into the research for DLSS.According to the different operation ways,the patients were randomly divided into the modified PEID group(observation group) and traditional PEID group (control group) according to the digital table method,30 cases in each group.The surgical outcome,indicators included the change in spinal canal,visual analogue scale (VAS) score and Oswestry disability index (ODI) at pre-operation,postoperative 3 d,postoperative 3 months and postoperative 6 months,operation time,headache and painful stiff nape incidence in the operation,postoperative complications were compared between the two groups.Results The VAS scores (postoperative 3 days,postoperative 3 months and postoperative 6 months) of the observation group were (4.37 ± 1.20) points,(2.59 ± 1.30) points,(1.29 ± 1.21)points respectively,which of the control group were (4.45 ± 1.22)points,(2.67 ± 1.36)points,(1.17 ± 1.10)points respectively,which were significantly better than (7.93 ± 1.56)points of the observation group and (8.22 ± 1.70) points of the control group before operation,the differences were statistically significant (F =1 254.387,512.762,all P ＜ 0.05).The ODI scores (postoperative 3 days,postoperative 3 months and postoperative 6 months) of the observation group were (48.64 ± 19.59) points,(27.66 ± 10.22) points,(10.69 ± 8.87) points respectively,which of the control group were (47.22 ± 20.96) points,(25.17 ± 11.93) points,(10.16 ± 7.89) points respectively,which were significantly better than (75.20 ± 23.20) points of the observation group and (70.35 ± 28.66) points of the control group before operation,the differences were statistically significant(F =1 254.387,512.762,all P ＜ 0.05).The VAS and ODI scores (pre-operation,postoperative 3 days,postoperative 3 months andpostoperative 6 months) of the observation group and control group had no statistically significant differences (VAS:t =2.088,2.124,3.021,3.173;ODI:t =2.366,1.079,1.694,1.573,all P ＞ 0.05).The incidence of neck pain and operation time of the observation group were 20.69％,(63 ± 7) min,which were significantly lower than 87.50％ and (157 ± 8)rin of the control group,the differences were statistically significant(t =3.601,2.167,all P ＜ 0.05).The central sagittal diameter of the spinal canal and the central transverse diameter of the spinal canal between the observation group and the control group had no statistically significant differences (x2 =4.260,t =3.694,all P ＞ 0.05).Conclusion Modified PEID has advantages in surgical efficiency,operation time and headache and painful stiff nape incidence compared with traditional PEID,so it can be chosen for DLSS.

Objective To explore the short-term and long-term efficacy of anterior cervical dis-cectomy and fusion(ACDF)under microscopic assistance for patients with focal ossification of the posterior longitudinal ligament(OPLL).Methods A total of 105 patients with focal OPLL treated between February 2020 and February 2022 were retrospectively selected.They were divided into mi-croscope group(n=56)and conventional group(n=49)based on whether ACDF was assisted by microscopy.Perioperative indicators,Visual Analogue Scale(VAS)scores,36-item Short-Form Health Survey(SF-36)scores,spinal canal cross-sectional area at the narrowest point,anteroposteri-or diameter of the spinal cord,cervical range of motion,intervertebral height,joint function[Japanese Orthopaedic Association(JOA)cervical spine disease score and Neck Disability Index(NDI)],and occurrence of complication were observed.Results The average operative time and average hospital stay in the microscope group were shorter than those in the conventional group[(141.85±18.35)min and(10.18±1.58)d versus(159.46±21.42)min and(12.03±1.82)d,P＜0.05].The average intraoperative blood loss in the microscope group was(80.65±7.28)mL,which was less than that(103.52±10.43)mL in the conventional group(P＜0.05).The VAS score and SF-36 score at six months postoperatively were better in the microscope group compared to the conventional group[(2.82±0.53)and(79.56±5.68)versus(3.51±0.60)and(72.35±4.77),respectively,P＜0.05].Spinal canal area and anteroposterior diameter of the spinal cord between the two groups postoperatively showed statistically significant differences[(138.24±24.32)mm versus(123.62±18.74)mm,(5.42±0.46)mm versus(4.73±0.51)mm,P＜0.05].The cervical range of mo-tion at six months postoperatively in the microscope group showed significant difference compared with that in the conventional group[(25.21±3.37)°versus(28.65±3.56)°,P＜0.05].The complication rate in the microscope group was lower than that in the conventional group(5.36％versus 18.37％,P＜0.05).Japanese orthopaedic association(JOA)and National Death Index(NDI)scores showed statistically significant between-group and time-point difference(P＜0.05).Conclusion Microscopic assistance during ACDF for focal OPLL provides a clear field of vision and facilitates effective decompression of the spinal cord by using a drill to remove and thin the ossified focus,thereby improving short-term pain and joint function while reducing the risk of spinal cord in-jury and other complications.
