Objective To review the research progress of Modic changes and its influence on lumbar interbody fusion. Methods The domestic and foreign literature related to Modic changes and its influence on lumbar interbody fusion was extensively reviewed. The etiology of Modic changes was summarized, and the treatment measures of Modic changes on lumbar interbody fusion were discussed. Results The etiology of Modic changes is not clear, which may be related to mechanical factors, autoimmune factors, low toxic infection factors, and genetic factors. Modic changes may lead to fusion failure and cage subsidence after lumbar interbody fusion. Preoperative evaluation of endplate sclerosis, reduction of iatrogenic endplate injury, fine operating of intervertebral space, management of osteoporosis, and selection of appropriate cage can prevent or reduce fusion failure or cage subsidence. Conclusion Modic changes may lead to fusion failure and cage subsidence after lumbar interbody fusion, and active perioperative intervention of Modic changes is helpful to improve the clinical prognosis.
ObjectiveTo provide a reference for the implementation of risk management in other medical institutions by introducing the practical experience of building a medical risk management system in West China Hospital of Sichuan University.MethodsBased on Donabedian’s SPO model, the practical experience in the construction of West China Hospital of Sichuan University was summarized from the aspects of structure, process, and results.ResultsThe establishment of medical risk management system made the hospital adverse event management effect good, and the risk management indicators were good. The average number of medical disputes in hospitals from 2016 to 2018 was 103.33, the average number of medical disputes per 100 medical practitioners was 7.01, the average number of medical disputes per 10 000 surgical cases was 6.55, and the average number of medical disputes per 10 000 cases was 0.18.ConclusionThe construction of medical risk management system is conducive to enhancing the awareness of medical risk prevention among medical institutions, continuously improving the quality of medical care and medical safety of hospitals, ensuring patient safety, promoting harmony between doctors and patients, and promoting the realization of healthy China.
Objective To learn the current situation of traditional Chinese medicine (TCM) systematic reviews/meta-analyses published in Chinese journals. Methods All TCM systematic reviews/meta-analyses published from 1978 to July 31, 2009 were searched in the Chinese Biomedical Database (CBM). According to the inclusion and exclusion criteria, relevant information was extracted on the basis of research purpose. Meanwhile, publication year, journal name, author’s district, number of authors and their articles, types of diseases and interventions were took as the indexes, and then descriptive analysis was performed using SPSS 15.0 software. Results A total of 245 articles including 238 in Chinese and 7 in English were included. All of them were published in 117 different journals from 1998 to 2008, showing an accelerating growth trend of article number. In addition to only one article with first author from Germany, the first author of other 244 were from 24 domestic provinces (autonomous regions and municipalities); the number of authors ranged from 1 to 11; a total of 186 people had published articles as first author, and the number of their published articles ranged from 1 to 29. There were 16 types of diseases according to the International Classification of Diseases 10th Edition (ICD-10). Totally, 218 articles took drugs as interventions (including 106 listed drugs, 25 self-made prescriptions, 70 related to both listed drugs and self-made prescriptions, and 17 without reporting detailed interventions), accounting for 89%; and 27 articles were about non-drug interventions (including 26 about acupuncture and 1 about massage), accounting for 11%. Most (95.8%) of the articles about self-made prescriptions and listed drugs/self-made prescriptions adopted inappropriate pooled analyses. Conclusion Evidence-based medicine has been spread into the field of TCM, the number of TCM systematic reviews/meta-analyses shows an accelerated growth trend. The types of diseases discussed in the literature were almost the same as the diseases those could be effectively treated by TCM, but there existed imbalance in districts. In the future, systematic review/meta-analysis on drug intervention should aim at Chinese patent medicines and single medicines rather than self-made prescriptions, and should pay more attention to advantageous drugs and advantageous treatments of diseases. Moreover, importance should be also attached to clinical heterogeneity controlling when using acupuncture as a non-drug intervention.
During the medical rescue of Wenchuan earthquake, West China Hospital immediately shifted to the two-track emergent system mode. More works have been done in time to cure and treat those critically ill patients effectively and to protect the medical safety of patients. The Activated Contingency Plans for major disasters have been started up to evacuate safely those mild patients in the hospital,to prevent out of danger and other accidents. More works have done on the identification of the injured or patients to improve the accuracy and strictly implement the "three investigations and seven right" system to prevent a wrong operation, or a wrong prescription, or a wrong transfusion. We have worked carefully on the referral the wounded, to referr the wounded to those Hospitals in Chengdu or other province and to prevent security incidents.
Objective To evaluate the surgical techniques and effectiveness of arthroscopic treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fracture with non-absorbable suture fixation combined with the mini-plate. Methods Between January 2009 and March 2012, 32 patients with ACL tibial eminence avulsion fractures were treated. There were 18 males and 14 females, aged 12-40 years (mean, 17.5 years). The injury causes included traffic accident injury in 15 cases, sport injury in 6 cases, and falling injury in 11 cases. The time from injury to operation ranged 7-18 days with an average of 9.5 days. Before operation, the results of Lachman test were all positive; the Lysholm score was 52.13 ± 4.22 and the International Knee Documentation Committee (IKDC) score was 44.82 ± 2.44. According to Meyers-McKeever classification criteria, there were 12 cases of type II and 20 cases of type III. After arthroscopic poking reduction of fracture, tibial eminence avulsion fractures were fixed with the Ethibond non-absorbable sutures bypass figure-of-eight tibial tunnel combined with the metacarpal and phalangeal mini-plate. Results Primary healing was obtained in all incisions; no joint infection or skin necrosis occurred after operation. All patients were followed up with an average time of 22.4 months (range, 12-50 months). The patients showed negative Lachman test at 12 weeks after operation. Except 3 patients having knee extension limitation at last follow-up, the knee extension range of motion (ROM) was normal in the other patients; the knee flexion ROM was normal in all patients. The Lysholm score and IKDC score were significantly improved to 94.19 ± 0.93 and 94.35 ± 1.22 at last follow-up, showing significant differences when compared with preoperative values (t=55.080, P=0.000; t=101.715, P=0.000). Conclusion The arthroscopic treatment of ACL tibial eminence avulsion fracture with Ethibond non-absorbable suture fixation combined with mini-plate is an effective procedure with the advantages of minimal trauma, reliable fixation, and satisfactory recovery of the knee joint function.
