Objective To explore the serious situation of injection abuse, and its influence to average prescription fee. Methods The subjects of this study were health service settings in rural area of 9 provinces/cities in Midwest of China. The treatment prescription indicators of county and village health service settings were calculated. Results Prescription injection rates of health care facility in rural area of Midwest provinces/cities of China (25.8% to 62.2%,mean: 45.1%) were higher than the standard of WHO (13.4% to 24.1%), and the injection abuse situation was serious. Injection bause caused the increase of prescription fee. Excess usage of injection in health service settings was related to the economic level of the on-site county or village, and also related to the size and load of health service facilities. Conclusion Suggestions are proposed to the government health agency according to the results of the study: enhancing the lawmaking, establishing the related policy and effective measure, training the medical personnel, promoting the mass health education, investigating the effective injection management model in rural area, and reducing the rate of injection.
Objective To analyze the efficacy of off-pump coronary artery bypass grafting (OPCABG) in elderly patients with coronary artery disease complicated with moderate ischemic mitral regurgitation. Methods The clinical data of patients aged≥70 years with coronary artery disease complicated with moderate mitral regurgitation, and undergoing OPCABG from January 2009 to January 2020 in Beijing Anzhen Hospital were retrospectively analyzed. The echocardiographic indicators of the patients were compared preoperatively, postoperatively before discharge and during the follow-up. Results Finally 239 patients were enrolled. There were 136 males and 103 females, aged 74.1±3.2 years. Before postoperative discharge, 49 (20.5%) patients had no mitral regurgitation, 144 (60.3%) mild regurgitation, 46 (19.2%) moderate regurgitation, and 0 severe regurgitation. The area of mitral regurgitation was significantlyimproved (2.5±1.8 cm2 vs. 5.6±1.0 cm2, P<0.001). There were 10 (4.2%) patients of hospital death, 23 (9.6%) of low cardiac output, 3 (1.3%) of myocardial infarction, and 8 (3.3%) of nervous system injury after operation. As a result, 208 (90.8%) patients were followed up and the mean follow-up time was 3.4 years (range 1-9 years). The cumulative survival rates at postoperative 2, 4, 6, and 8 years were 95.8%, 88.0%, 78.4%, and 73.1%, respectively. Postoperative follow-up showed significant improvements compared with those before surgery in the area of mitral regurgitation, left ventricular ejection fraction, left ventricular end-diastolic and left ventricular end-systolic diameters (all P＜0.05). Duirng the follow-up, the major adverse cardiac and cerebrovascular events were all cause death in 22 (10.6%) patients, including cardiac death in 17 (8.2%) patients, myocardial infarction in 7 (3.4%) patients, heart failure in 24 (11.5%) patients, cerebrovascular events in 11 (5.3%) patients, re-hospitalization due to heart disease in 23 (11.1%) patients, and none of the patients with myocardial infarction were revascularized. Conclusion The mid- and long-term outcomes of OPCABG in the treatment for elderly patients with coronary artery disease complicated with moderate ischemic mitral regurgitation is good.
Objective To assess the application value of 3-dimensional(3D) printing technology in surgical treatment for congenital tracheal stenosis. Methods We retrospectively analyzed the clinical data of preoperative diagnosis, intra-operative decision-making and postoperative follow-up of four children with congenital tracheal stenosis under the guidance of 3D printing in our hospital between February 2013 and May 2014. There were 3 males and 1 female aged 23.0±7.1 months. Among them, two children were with pulmonary artery sling, one with ventricular septal defect, and the other one with tetralogy of Fallot. The airway stenosis was diagnosed preoperatively by chest CT scan and 3D printing tracheal models, and was confirmed by the help of bronchoscopy under anesthesia. During operation the associated cardiac malformation was corrected firstly under extracorporeal circulation followed by tracheal malformation remedy. The design and implementation of tracheal operation plans were guided by the shape and data from 3D printing trachea models. There were two patients with long segment of tracheal stenosis who received slide anastomosis. And the other two patients were characterized with tracheal bronchus, one of which combined ostial stenosis of right bronchial performed extensive slide anastomosis, and the other one performed end to end anastomosis. Results All the children’s preoperative 3D printing trachea models were in accord with bronchoscopy and intra-operative exploration results. Intra-operative bronchoscopy confirmed that all tracheal stenosis cured completely. All anastomotic stomas were of integrity, and all the luminals were fluent. There was no operative death or no serious complication. During 1-2 years follow-up, all patients breathed smoothly and their airways were of patency by postoperative 3D printing trachea model. Conclusion 3D printing can provide a good help to congenital tracheal stenosis in preoperative diagnosis, the design of operation plan, intra-operative decision-making and manipulation, which can improve the operation successful rate of tracheal stenosis.
Objective To analyze the effects of different surgical methods on postoperative pulmonary function and exercise capacity in patients with non-small cell lung cancer (NSCLC), so as to explore whether it can effectively improve pulmonary function and promote the recovery of exercise capacity by reducing the number of trocars ports and the resection of normal lung tissues. Methods The clinical data of NSCLC patients who underwent surgery in the First Affiliated Hospital of Hebei North University from January 2016 to June 2019 were collected retrospectively. According to the surgical methods, they were divided into three groups: single utility port video-assisted thoracic surgery (SP-VATS) segmentectomy group, SP-VATS lobectomy group and three port video-assisted thoracic surgery (TP-VATS) lobectomy group. The changes of pulmonary function [forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximal voluntary ventilation (MVV)] and 6-minute walking distance (6MWD) at different time points [1st day before the operation (T0); 3rd day (T1), 7th day (T2), 1st month (T3), 3rd month (T4), 6th month (T5) and 1st year (T6) after the operation] were compared among the three groups. Results A total of 342 patients were included, including 102 in SP-VATS segmentectomy group, 116 in SP-VATS lobectomy group and 124 in TP-VATS lobectomy group. Except for pathological type and TNM stage (P<0.05), there was no significant difference in general information, preoperative pulmonary function or 6MWD among the three groups (P>0.05). The pulmonary function and 6MWD of the three groups before and after operation were not affected by pathological type or TNM stage (P>0.05). Except at T6 time point (P>0.05), there were significant differences in postoperative pulmonary function and 6MWD among the three groups at T1-T5 time points (P<0.05). Intra group comparison of pulmonary function and 6MWD in the three groups showed that the operation had the least impact on patients in SP-VATS segmentectomy group with the fastest recovery, followed by SP-VATS lobectomy group, and SP-VATS lobectomy group was the worst. Conclusions Video-assisted thoracoscopic for NSCLC can improve pulmonary function and promote the recovery of exercise capacity by reducing the number of trocars ports and the resection of normal lung tissues. However, this advantage is mainly reflected in the early postoperative stage.
ObjectiveTo evaluate the clinical effects of segmentectomy versus lobectomy under single utility port video-assisted thoracic surgery on inflammatory factors and immune cells in peripheral blood of non-small cell lung cancer patients, and to analyze the effect of changes of postoperative inflammatory factors and immune cells on the prognosis of the patients.MethodsThe clinical data of 256 patients who underwent segmentectomy or lobectomy under single utility port video-assisted thoracic surgery for non-small cell lung cancer in the First Affiliated Hospital of Hebei North University from January 2016 to October 2020 were retrospectively collected. According to the operation method, they were divided into a segmentectomy group (126 patients with 79 males and 47 females at an age of 63.4±6.2 years) and a lobectomy group (130 patients with 91 males and 39 females at an age of 62.9±5.6 years). The change of inflammatory factors (C reactive protein, interleukin-6, interleukin-8, tumor necrosis factor-α) and immune cells (CD4+T cells, CD8+T cells and natural killer cells) were recorded and analyzed before operation (T0) and 1 day (T1), 3 days (T2), 7 days (T3), 1 month (T4) after the operation between the two groups. According to postoperative recurrence situations, they were divided into a recurrence group and a non-recurrence group, multivariate logistic regression analysis was used to analyze the relationship between the change of postoperative inflammatory factors, immune cells, and the prognosis of patients with non-small cell lung cancer.Results(1) There was no statistical difference in sex ratio, underlying diseases, body mass index, levels of preoperative inflammatory factors or immune cells between the two groups (all P>0.05). (2) The changes of postoperative inflammatory factors in the segmentectomy group were significantly less than those in the lobectomy group at T1-T3 (all P<0.05), and the changes of postoperative immune cells in the segmentectomy group were significantly less than those in the lobectomy group at T1-T4 (all P<0.05). (3) The changes of postoperative inflammatory factors and immune cells on postoperative day 3 in the recurrence group were significantly more than those in the non-recurrence group (all P<0.05). (4) Multivariate logistic regression analysis showed that the changes of postoperative inflammatory factors and immune cells on postoperative day 3 may be the risk factors for postoperative recurrence and metastasis in patients with non-small cell lung cancer (all P<0.05).ConclusionSingle utility port video-assisted thoracic surgery segmentectomy for the treatment of non-small cell lung cancer can reduce the inflammatory response and protect body's immune function, and the change of postoperative inflammatory factors and immune cells in postoperative day 3 may be the risk factors for postoperative recurrence and metastasis in patients with non-small cell lung cancer.
