Objective To study the sugical treatment of elderly patients with acute intestinal ob-struction caused by colorectal cancer. Methods The clinical data of 56 elderly patients of acute colonic ob-struction caused by colorectal cancer from Janury 2002 to Janury 2007 were analyzed retrospectively. There were 20 cases with right side coloniclesion,32 cases with left side coloniclesion and 4 cases with rectal lesion. All patients received emergency operation. One stage tumor resection and anastomosis was performed in 20 cases with right side coloniclesion and in 25 cases with left side coloniclesion,Hartmann operation in 4 cases,proximal colostomy in 3 cases were performed with left side coloniclesion. Dixon operation in 2 cases and proximal colostomy in 3 cases were performed with rectum cancer. Results Postoperative complications occurred in 18 cases,including wound infection,intraperitoneal sepsis and intestinal fistula. Fifty-five cases recovered,there was one perioperative death. Conclusions Positive operation should be taken when the diagnosis of acute obstructing colorectal cancer the elderly is made. The operative methods depended on the patient'conditions. The perioperative managment should be emphasized and selection of rational operation procedure is important for decreasing mortality and complications of acute obstructing colorectal cancer in the elderly.

The acyl-CoA synthetase long-chain (ACSL) belongs to an enzyme encoded by a polygenic family. ACSL, located in the endoplasmic reticulum and outer mitochondrial membrane, can catalyze fatty acids to form acyl-CoA, participating in many physiological processes, such as fatty acid metabolism and membrane modification. The ACSL family plays different roles in the fatty acid metabolism of different cells, and its dysfunction can lead to conditions such as fatty liver, arteriosclerosis, and diabetes. As a major subtype of the ACSL family in the liver, ACSL family member 1 (ACSL1) is mainly involved in the maintenance of cholesterol stability, fatty acid activation, and bile acid metabolism. It is also associated with the development of certain liver diseases such as hepatocellular carcinoma and steatosis. This paper reviews differences in physiological functions and functional characteristics of ACSL family members. It also discusses the advances in studies on the role of ACSL1 in influencing lipid metabolism, regulating cellular iron death, and the development of related diseases such as liver fibrosis, hepatocellular carcinoma, cachexia, steatosis, thyroid cancer, and breast cancer.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

TSCI have dyskinesia and sensory disturbance that can cause various life-threaten complications. The patients with traumatic spinal cord injury (TSCI), seriously affecting the quality of life of patients. Based on the epidemiology of TSCI and domestic and foreign literatures as well as expert investigations, this expert consensus reviews the definition, injury classification, rehabilitation assessment, rehabilitation strategies and rehabilitation measures of TSCI so as to provide early standardized rehabilitation treatment methods for TSCI.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
