Objective To study factors associated with necrosis and calcification of cyst echinococcosis. Methods This study retrospectively analyzed 191 cases of hepatic cycstic echinococcosis admitted from 2005 to 2008 in the First Affiliated Hospital of Xinjiang Medical University Department of General Surgery, possible relevant factors screened were the patients' gender, age, operation frequency, hepatitis, gall stones, calcium of blood serum, multiple hepatic hydatid cyst, biliary fistulae and hepatic cycstic echinococcosis degeneration. Single-factor analysis and multi-factors analysis were conducted. Results The single-factor independent samples t-test showed that age is significantly related to hepatic cycstic echinococcosis degeneration (t = - 2. 455, P = 0. 008). Single factor Chi-square test showed that factors impacting on hepatic cycstic echinococcosis degeneration were multiple hepatic hydatid cyst and the biliary fistulae (x2 = 6. 848, P = 0. 009; x2 = 7. 149, P = 0. 008). The multiple-factor Logistic regression analysis showed that the age, the multiple hepatic hydatid cyst, and biliary fistulae are the related risk factors(x2 =5. 306,P = 0. 021,OR = 1. 665;x2 = 10. 377,P =0. 001,OR =3. 300;x2 = 4.455,P =0. 035, OR =2. 164) of hepatic cycstic echinococcosis patients with cyst echinococcosis degeneration. Conclusions Age, multiple hepatic hydatid cyst and biliary fistulae are the risk factors associated with degenerative necrosis and calcification of hepatic echinococcosis.

AIM To analyze the mechanism of the adriamycin induced cardiomyopathy. METHODS The patch clamp technique in the whole cell recording was used to study the effect of adriamycin on L type calcium channel current( I Ca L ) in the isolated cardiomyocyte of the guinea pig. RESULTS The current voltage( I U ) curveshowed the bell shape in the control and in 0 1 mmol?L -1 adriamycin. Their peak potentials were about +10 mV. The amlitude of peak calcium current increased from (-0 93?0 05) nA to (-1 31?0 08) nA( P

BACKGROUND: Adequate preparation of donors and recipients prior to living-related donor renal transplantation, short warm and cold ischemia time for donor kidney, good histocompatibility of human leukocyte antigen match, and low postoperative rejection incidence provide feasibility for use of low-dose immunosuppressive agents after living-related donor renal transplantation. OBJECTIVE: To investigate the safety and effectiveness of low-dose calcineurin inhibitors (CNI), an immunosuppressive agent, in living-related donor renal transplantation. METHODS: A total of 38 recipients who underwent living-related donor renal transplantation at the Center of Renal Transplantation of the First Affiliated Hospital of Nanjing Medical University from January 2006 to June 2008 were randomized for treatment with mycophenolate mofetil (750 mg twice a day), prednisone, and either standard-dose CNI (n=18) or low-dose CNI (n=20) during 12 months post-transplantation. Ciclosporin A was given orally (starting dose, 6 and 4 mg/kg per day, respectively) in two divided doses to achieve the 12-hour whole blood concentration as measured by fluorescence polarization immunoassay. The starting dose of tacrolimus was 0.12 and 0.08 mg/kg per day respectively, and its whole blood concentration was measured by enzyme-multiplied immunoassay technique. After transplantation, patients were followed up. Renal function, pulmonary infection, liver dysfunction, and CNI nephrotoxicity at different time periods were compared between different regimens. RESULTS AND CONCLUSION: During 12 months post-transplantation, patient death occurred in one of 18 patients (5.6%) in the CNI standard-dose group and none of 20 patients (0%) in the CNI low-dose group. There was no significant difference in renal function and acute rejection between CNI standard-dose and CNI low-dose groups (P > 0.05). The incidence of liver dysfunction and CNI nephrotoxicity was significantly lower in the CNI low-dose group than in the CNI standard-dose group (P < 0.05). In addition, a low-dose CNI regimen helped recipients to lessen the economic burdens. These findings indicate that it is effective, safe and economical to use a low-dose CNI regimen in living-related donor renal transplantation.

In August 2023， the European Society for Organ Transplantation （ESOT） published the ESOT Consensus Statement on Biomarkers in Liver Transplantation online. The consensus statement focuses on biomarkers in liver transplantation， clinical applicability， and future needs and explores the role of new biomarkers in predicting liver transplantation outcomes by reviewing the literature on primary disease recurrence， development of chronic kidney disease （CKD）， and safe weaning of immunosuppression. This consensus statement conducts studies from the four aspects of recurrent liver disease after liver transplantation， recurrent hepatocellular carcinoma， weaning of immunosuppression， and CKD progression， emphasizes the importance of biomarkers in predicting or detecting disease recurrence， and proposes that large-scale prospective studies are still needed to improve the quality of evidence. The author’s team gives an excerpt of the consensus statement and systematically introduces the four aspects of the consensus statement and related discussions and conclusions， in order to provide more evidence-based medical evidence for identifying and exploring new biomarkers for liver transplantation.

Objective:To explore diagnostic value of tumor necrosis factor-α (TNF-α) in patients with pulmonary infection after liver transplantation.Methods:The clinical data of 80 patients with pulmonary infection after liver transplantation in the the First Affiliated Hospital of Xinjiang Medical University from January 2016 to May 2019 were retrospectively analyzed. According to different pathogens, they were divided into bacteria infection group ( n=35) and non-bacteria infection group ( n=45). The general data, levels of serum TNF-α, C-reactive protein (CRP) and procalcitonin (PCT) were compared between the two groups. Logistic regression was performed to explore risk factors for pulmonary infection after liver transplantation. Receiver operating characteristic (ROC) curves were performed to analyze diagnostic value of TNF-α, CRP and PCT. Results:The levels of serum TNF-α, CRP and PCT in bacteria infection group were significantly higher than those in non-bacteria infection group ( P<0.05). Multivariate analysis showed that high TNF-α, CRP, and PCT levels were independent risk factors for bacterial pneumonia after liver transplantation. ROC analysis showed that sensitivity, specificity and areas under ROC curves (AUC) of TNF-α, CRP and PCT for diagnosis of bacterial pulmonary infection after liver transplantation were (80.12%, 72.12%, 80.18%), (83.45%, 73.46%, 83.38%) and (0.802, 0.751, 0.803), respectively. The AUC, sensitivity, and specificity between TNF-α and PCT for diagnosis of bacterial pulmonary infection after liver transplantation were similar ( P>0.05). The AUC, sensitivity and specificity of TNF-α for diagnosis of bacterial pulmonary infection after liver transplantation were better than those of CRP ( P<0.05). Conclusions:The diagnostic value of TNF-α for pulmonary infection after liver transplantation is similar to that of PCT, and is superior to CRP. It can be applied as a reliable index for identifying bacterial pneumonia and non-bacterial pneumonia.
