Hemodynamically unstable pelvic fracture results from blunt external force and is often accompanied by hypotension. Massive blood transfusion is needed in the case and the mortality rate can be 40%-65%. The key to the early treatment of hemodynamically unstable pelvic fracture lies in bleeding control. Currently, the primary methods of hemostasis include pelvic brace fixation, pre-peritoneal pelvic packing, internal iliac artery ligation, internal iliac artery embolization, etc. However, due to the urgent need for emergency hemostasis and the difficulty in identifying the bleeding sites, hemodynamically unstable pelvic fracture remain a serious challenge for trauma surgeons. Pre-peritoneal pelvic packing used in emergency situations to control the bleeding hemodynamically unstable pelvic fracture can effectively control venous and fracture-site bleeding after pelvic fracture and reduce mortality. Moreover, it is easy and convenient to operate and is especially suitable for cases in which angiographic embolization can not be performed immediately or the patients are hemodynamically extremely unstable. However, there is still a controversy in the clinical practice regarding the selection between pre-peritoneal pelvic packing and other hemostatic methods such as angiographic embolization. To this end, the author reviewed the progress of the researches on the application of pre-peritoneal pelvic packing in emergency hemostasis for hemodynamically unstable pelvic fracture, aiming to provide a reference for its clinical treatment.

[Purpose]To analyze the screening results of urban cancer early diagnosis and treat-ment program in Shaanxi Province from 2021 to 2022.[Methods]The risk assessment and clini-cal screening data of five high incidence malignant tumors(female breast cancer,lung cancer,upper gastrointestinal cancer,liver cancer and colorectal cancer)in the urban cancer early diag-nosis and treatment program in Shaanxi Province were collected and analyzed.The high-risk rate,screening compliance rate,and positive detection rate of the above 5 types of malignant tumors were calculated.[Results]A total of 17 921 urban residents in Shaanxi Province completed the cancer risk survey from 2021 to 2022(44.12％were males and 55.88％were females),9 270 were identified as high-risk(51.7％):34.2％for breast cancer,24.2％for lung cancer,20.7％for upper gastrointestinal cancer,7.5％for liver cancer,and 29.8％for colorectal cancer.Among 18 145 person-times of high-risk,6 357 person-times underwent clinical screening,with an overall com-pliance rate of 35.0％.The participating number and compliance rate of individual cancer screening were 1 451 person-times(42.3％)for female breast cancer,2 064 person-times(47.7％)for lung cancer,1 125 person-times(30.4％)for upper gastrointestinal cancer,468 person-times(35.0％)for liver cancer,and 1 249 person-times(23.4％)for colorectal cancer.The detected positive cases and the detection rate were 142 cases(9.8％)for frmale breast cancer,373 cases(18.1％)for lung cancer,13 cases(1.2％)for upper gastrointestinal cancer,8 cases(1.7％)for liver cancer,and 68 cases(5.4％)for colorectal cancer.[Conclusion]The screening results of early diagnosis and treatment project for urban cancer in Shaanxi Province shows a relative higher risk rate and lower compliance rate with significant differences among various types of cancer.
