  • The effects of physiotherapy on pulmonary function in COPD patients with primary lung cancer undergoing lung resection

    Objective To assess the effects of physiotherapy on pulmonary function in COPD patients with lung cancer after lobectomy or pneumonectomy. Methods Fifty-five COPD patients with lung cancer undergoing lobectomy or pneumonectomy from January 2005 to May 2014 were recruited in the study. They were divided into group A received comprehensive physiotherapy before surgery and group B without comprehensive physiotherapy before surgery. The changes of lung function and tolerance were compared before physiotherapy (T1 time point) and after physiotherapy (T2 time point) in the group A, and between two groups before lung resection (T2 time point) and after lung resection (T3 time point). Results In group A, the forced expiratory volume in one second (FEV1), vital capacity (VC), peak expiratory flow at 50% of vital capacity (FEF50) and FEF25 increased significantly respectively by 16.96%, 14.75%, 20.69% and 13.79% compared with those before physiotherapy. Meanwhile, six-minutes walking distance (6MWD) achieved a significant improvement. After resection of lung, FEV1 and VC appeared to reduce, and pulmonary small airway function, tolerance, and clinical features deteriorated significantly. The differences between T2 and T1 in FEV1, FEF50 and FEF25 in the patients with FEV1%pred ≥80% and 50%-80% were similar with those in the patients with FEV1%pred<50%. The differences between T2 and T3 in FEF50 and FEF25 in the patients with FEV1%pred≥80% and 50%-80% were higher than those with FEV1%pred<50%. For the patients with lobectomy, FEV1 and VC in the group B were lower than those in the group A (FEV1: 10.24% vs. 22.44%; VC: 10.13% vs. 20.87%). For the patients with pulmonary resection, FEV1 and VC had little differences (FEV1: 36.33% vs. 36.78%; VC: 37.23% vs. 38.98%). Conclusion Physiotherapy is very important for the preoperative treatment and postoperative nursing of COPD patients with primary lung cancer.

  • CLINICAL EVALUATION OF EFFECT OF TRANSPLANTATION BY AUTO-FAT GRANULE INJECTION FORMASTATROPHY POST SUCKLING

    【Abstract】 Objective To investigate the cl inical effect of transplanting by auto-fat granule injection for mastatrophy post suckl ing. Methods From March 2000 to June 2006, 73 patients(146 breasts ) with mastatrophy post suckl ing were treated by transplanting auto-fat granule. The mastatrophy occurred between ages 28 and 52 years with a median of 37 years post suckl ing. The breasts shrank and their elasticity decreased gradually within 2-10 years post suckl ing. The autofat granule was obtained by l iposuction with syringe from patient’s abdomen, waist, buttocks and thighs, etc. After repeated wash and purification, the auto-fat granule was transplanted into the interspace behind the breast by injection. The quantity of auto-fat granule was 50-100 mL in each side of breast per transplantation at 3-6 months intervals, and the whole course of treatment needed 2-6 transplantations. Results The incisions in all cases healed primarily postoperatively. In 73 cases, 65 were followed up from 6 months to 3 years post operation. All patients had a significant improvement in their breast size and shape postoperatively and their breasts were soft and natural in appearance and feel. All of them had more perfect arcuation ofphysique and body with strengthened self-confidence, rel ieved mood and improved qual ity of l ife. However, small indurations were found sporadically in 7 cases (10 breasts) within 2-7 months, and calcifications in 5 cases (8 breasts) within 9-14 months post the first operation. Conclusion The transplantation by auto-fat granule injection for mastatrophy post suckl ing is an effective and practical method. The surgical technique is well worth performing in cl inical practice.

  • Effect of pulmonary hypertension on the prognosis of patients with severe aortic stenosis after transcatheter aortic valve replacement: A systematic review and meta-analysis

    Objective To systematically evaluate the impact of pulmonary hypertension (PH) on the prognosis of patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). Methods We conducted a computer-based search of databases including CNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library, EMbase and Web of Science from the inception of the databases to June 2023. Two reviewers independently screened articles, extracted data and assessed the quality of the included studies. Meta-analysis was performed using Stata 17.0 software. Results A total of 16 cohort studies with Newcastle-Ottawa Scale score≥7 were included. Meta-analysis results demonstrated that patients with PH who underwent TAVR had significantly higher rates of all-cause mortality at 1 year [OR=2.10, 95%CI (1.60, 2.75), P<0.01, I2=75%], 30 days [OR=2.09, 95%CI (1.54, 2.83), P<0.01, I2=33%] and cardiovascular mortality [OR=1.49, 95%CI (1.18, 1.90), P<0.001, I2=41%], compared to those without PH. There was no statistical difference between the two groups in major bleeding events, stroke, myocardial infarction, pacemaker implantation or postoperative renal failure. Subgroup analysis was conducted for some outcome indicators with significant heterogeneity from the aspects of PH measurement methods, PH diagnostic criteria and different PH types, and the results showed that most outcome indicators were subcombined and the direction was consistent with the overall result, and the heterogeneity was significantly reduced. Conclusion PH can significantly increase the 30 days, 1-year, and cardiovascular mortality rates in severe AS patients undergoing TAVR surgery.
