ObjectiveTo explore the methods of prevention and treatment of the iatrogenic biliary-tract injury.Methods22 cases with the iatrogenic biliary-tract injury were analyzed retrospectively.ResultsModified Roux-en-Y choledochojejunostomy was performed in 11 cases, end-to-end anastomosis of bile duct in 4 cases, repair of bile duct in 2 cases, a drainage of the inter bile duct and the abdominal cavity in 5 cases. Only 1 case of common bile duct injury after laparoscopic cholecystectoy was death from the toxic shock, another case of bile duct injury after conventional cholecystectoy with the drainage of abdominal cavity was death from multiple system organ failure, all of the other patients were cured.ConclusionThe iatrogenic biliary-tract injury may be causes variously, and should be discovered as soon as possible and be operated in time.

OBJECTIVETo evaluate the risk of nasopharyngeal carcinoma (NPC) through EB virus antibody profile by enzyme linked immunosorbent assay (ELISA).

METHODSEBNA 1/IgA, EBNA 1/IgG and zta/IgG by ELISA and VCA/IgA by immmunoenzymatic method were detected in 121 NPC patients and 332 healthy subjects (HS) in the Pearl river estuary.

RESULTSThe sensitivity rates were 85%, 83% and 79% for EBNA 1/IgA, EBNA 1/IgG and zta/IgG, all three of which if combined was the highest 92%. The specificity rates were 86%, 86% and 80% for EBNA 1/IgA, EBNA 1/IgG and zta/IgG, all three of which if combined was also the highest 93%. According to the level of odds ratio, nasopharyngeal carcinoma risk could be divided into 3 groups: low, moderate and high-risk groups. 93% of HS had low risk of NPC with the odds ratio 0.0 to 0.3. 0.4% of HS had high risk of NPC with the odds ratio of 137.9%.

CONCLUSIONELISA is more objective than the traditional immunoenzymatic method in the detection and diagnosis of NPC. The combination of EBNA 1/IgA, EBNA 1/IgG and zta/IgG is able to evaluate the risk of NPC.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.
