Objective To evaluate the effect of selective angiography and embolization for the pa-tients with haemodynamically unstable pelvic fracture. Methods Sixty-two patients with haemodynami-cally unstable pelvic fracture were treated in our hospital from 2002 to 2008. Their pelvie fractures were classified on the basis of their X-ray and CT data. By AO classification, there were 2 cases of type A2, 6 B1, 9 B2, 8 B3, 16 C1, 13 C2, and 8 C. There were 6 cases of open injury (by Gustilo classification, 1 type Ⅱ and 5 type Ⅲ). Of the 46 eases of multiple injuries, 12 had shock. While active fluid infusion and vascular medication were conducted, the angiograph was done for all patients, 59 of whom also received embolization. Results Seventy-nine angiographs were performed for the 62 cases, and 12 of them received more than twice angiographa. Exams revealed that 32 patients had suffered injury to more than 2 arteries. The injured arteries were sequentially superior gluteal artery, iliolumbar artery, lateral sacra] artery, obturator artery, inferior gluteal artery, internal pudendal artery, internal iliae artery and external lilac artery. Of the 59 cases of embolization, 56 were successful. Seven patients died due to severe abdominal organ injury. Forty-five patients got an average follow-up of 14 months (range, 6 to 52 months) . No severe complications were no-ticed. Conclusions Selective angiography and embolization is an effective intervention for patients with haemodynamically unstable pelvic fracture. It is mandatory to conduct recurrent angiographic embolization for patients with multiple artery injuries or delayed artery injuries.

BACKGROUND: Lung cancer is the leading cause of cancer-related death in China. The results from a randomized controlled trial using annual low-dose computed tomography (LDCT) in specific high-risk groups demonstrated a 20% reduction in lung cancer mortality. The aim of tihs study is to establish the China National lung cancer screening guidelines for clinical practice. METHODS: The China lung cancer early detection and treatment expert group (CLCEDTEG) established the China National Lung Cancer Screening Guideline with multidisciplinary representation including 4 thoracic surgeons, 4 thoracic radiologists, 2 medical oncologists, 2 pulmonologists, 2 pathologist, and 2 epidemiologist. Members have engaged in interdisciplinary collaborations regarding lung cancer screening and clinical care of patients with at risk for lung cancer. The expert group reviewed the literature, including screening trials in the United States and Europe and China, and discussed local best clinical practices in the China. A consensus-based guidelines, China National Lung Cancer Screening Guideline (CNLCSG), was recommended by CLCEDTEG appointed by the National Health and Family Planning Commission, based on results of the National Lung Screening Trial, systematic review of evidence related to LDCT screening, and protocol of lung cancer screening program conducted in rural China. RESULTS: Annual lung cancer screening with LDCT is recommended for high risk individuals aged 50-74 years who have at least a 20 pack-year smoking history and who currently smoke or have quit within the past five years. Individualized decision making should be conducted before LDCT screening. LDCT screening also represents an opportunity to educate patients as to the health risks of smoking; thus, education should be integrated into the screening process in order to assist smoking cessation. CONCLUSIONS A lung cancer screening guideline is recommended for the high-risk population in China. Additional research , including LDCT combined with biomarkers, is needed to optimize the approach to low-dose CT screening in the future.
