Objective To evaluate the value of endorectal ultrasonography (ERUS) in assessment of mesorectal fascia (MRF) invasion in rectal cancer.Methods Data of 44 patients who accepted preoperative ERUS and total mesorectal excision surgery within a week were retrospective analyzed.There were 18 patients who accepted preoperative neoadjuvant chemotherapy and 26 patients didn't acceped.Taking the pathological diagnosis of circumferential resection margin (CRM) as the gold standard,the diagnostic efficiency of ERUS for the MRF invasion in rectal cancer was evaluated.Results The final pathological T staging was T1 in 2 cases,T2 in 17 cases and T3 in 25 cases.There were 2 cases of CRM positive results,and 42 cases of CRM negative results.With regard to the location of tumor,there were 16 cases located in low,and 28 cases in mid rectum.There were 26 cases located in anterior or antero-lateral wall of rectum,13 cases in posterior or postero-lateral wall,and 5 cases with a circle of rectum.The diagnostic accuracy were 83.33 ％ (15/18) and 92.31％ (24/26) for cases of accepting and not accepting the preoperative neoadjuvant chemotherapy;80.77％ (21/26) for cases located in anterior or antero-lateral wall,and 100％ (13/13) for cases located in posterior or postero-lateral wall;75.00％ (12/16)and 96.43 ％ (27/28) for low position and mid position tumors.The total diagnostic accuracy was 88.64％ (39/44).Conclusion ERUS can be an effective method in preoperative assessment of the MRF invasion in rectal cancer.

BACKGROUND:To reduce the amount of bleeding and the amount of hemoglobin after total knee replacement has been a key project in the clinical research in the division of bone and joint. Currently, ice therapy has been widely used in the clinic for tissue sweling and pain due to various physical and chemical factors. OBJECTIVE:To investigate the risk factors of postoperative hemoglobin after total knee replacement and discuss the effects of ice intervention. METHODS: 240 patients with osteoarthritis based on the random draw principles were equaly divided into the treatment group and the control group. The general information, disease status, diagnosis and treatment and prognosis of the two groups were investigated. Al patients were actively subjected to artificial total knee replacement. On the basis of the treatment in the control group, the treatment group received ice intervention at 2 hours after replacement for 7 consecutive days. RESULTS AND CONCLUSION:The postoperative hemoglobin decrease occurred in 34 patients, with the incidence of 14.2% among 240 patients at 7 days after replacement. Multivariate logistic regression analysis results showed that age, no ice treatment, body mass index were the main risk factors for hemoglobin decrease after total knee replacement (P < 0.05). Compared with the control group, the postoperative hemoglobin values of the treatment group were significantly higher (P < 0.05). Hemoglobin decrease values, total blood loss, blood transfusion rate, blood transfusion amount, and pain score at 3 and 7 days after replacement were significantly lower in the treatment group than in the control group (P < 0.05). The knee function excelent and good rate was 96.7% in the treatment group, and 95.8% in the control group, which showed no significant difference (P > 0.05). Results verify that clinical application of total knee replacement facilitated the knee recovery in patients with osteoarthritis, but hemoglobin decrease and bleeding existed. Active ice intervention can reduce the risk and relieve postoperative pain.

In recent years, significant progress has been achieved in heart transplantation, perioperative management and application of immunosuppressants. Nevertheless, complications after heart transplantation are still main risk factors affecting the survival of recipients. Among them, acute kidney injury is a common complication during the early stage following heart transplantation. It may lead to secondary chronic kidney diseases after heart transplantation and progress into end-stage renal diseases, severely affecting the quality of life and long-term survival of recipients. Therefore, it is of significance to identify the risk factors of kidney injury after heart transplantation and deliver prompt interventions to improve clinical prognosis of heart transplant recipients. In this article, research progress on the incidence, risk factors, prevention and treatment strategies of kidney injury-related complications after heart transplantation was reviewed, aiming to provide reference for the prevention, diagnosis and treatment of kidney injury-related complications after heart transplantation and enhance clinical prognosis of recipients undergoing heart transplantation.

Liver ischemia reperfusion injury (IRI) is one of the main causes of liver dysfunction or functional failure after liver transplantation or liver resection. As the main organ of lipid metabolism, liver is closely related to lipid metabolic balance. Lipoxygenase is a non-heme iron-containing oxidases that oxidizes polyunsaturated fatty acids to produce hydroxy-eicosanotetraenoic acid. Lipoxygenase is excessively expressed during liver ischemia, causing lipid metabolic disorders. High expression of several proinflammatory cytokines induced by lipoxygenase during liver reperfusion. Lipid peroxidation induced by lipoxygenase leads to the production of lipid oxygen free radicals, which induces iron death mainly characterized by lipid peroxidation, thus affecting apoptosis and tissue damage. This review mainly introduces the latest progress of lipoxygenase in liver IRI.
