Objective To study the curative effect of transcatheter arterial chemoembolization( TACE) combined with conventional percutaneous ethanol injection therapy ( PEIT) in the treatment for primary liver cancer?Methods Forty cases patients with primary liver cancer(the diameter was equal or more than 8 cm) who were treat in the Third Hospital of Qinhuangdao from January 2007 to May 2013 were selected,and randomly divided into treatment group(20 cases) and control group(20 cases)?The control group underwent TACE,the treatment group were given TACE combined with PEIT, the clinical effect of the two groups were observed?Results The effective rate of the treatment group was 80%,significantly higher than that of the control group( 50%) ,the difference was statistically significant( P=0?04)?During the follow?up of 3 years,there were 3 cases of portal vein tumor thrombus,5 cases of hepatic metastasis,1 case of upper gastrointestinal bleeding and 2 cases of liver failure in the control group;there were 1 case of liver metastasis,1 case of liver failure and death in the treatment group?Conclusion The test of the curative effect of patients with huge hepatocellular carcinoma after combination therapy with TACE and PEIT proved combination therapy can increase the curative effect, decrease impairment of liver funvtion?It was a palliation road to treat huge hepatocellular carcinoma.

Objective To investigate the blood pressure circadian rhythm in patients with IgA nephropathy by ambulatory blood pressure monitoring and explore its role in the disease progression. Methods A cross sectional study was carried out.Blood pressure rhythm was studied by ambulatory 24-hour monitoring with a portable oscillometric recorder in selected patients with primary IgA nephropathy.The term dipper was described as blood pressure during night dropped at least 10％ below daytime blood pressure.The term non-dipper referred to those in whom the nocturnal decline in blood pressure was less than 10％.Clinicopathological indices between dipper and non-dipper groups were compared. Results Ninety-three patients completed ambulatory blood pressure monitoring among whom 68 (73％) patients were non-dipper.The frequency of non-dipper was 70％,70％ and 81％ in the patients at chronic kidney disease stage 1,2 and 3 or more.The frequency did not differ among these three group patients (P=-0.587).77％ of patients with hypertension and 69％ of patients with normotension were non-dipper (P=0.373).The disappearance of blood pressure circadian rhythm in IgA nephropathy was not influenced by age,gender,blood pressure,proteinuria,renal function and renal pathology lesions.Among the patients who were followed up regularly for more than 12 months (n=54),patients in the dipper group had a trend of slower eGFR decline rate than those in non-dipper group albeit the difference was not significant (P=0.329).Subgroup analysis revealed that in patients with hypertension and non-dipper (n=29),the eGFR decline rate was much faster than that in dipper group[(-6.79±11.58 )vs (-0.34±1.74) ml ·min-1 ·(1.73 m2)-1·year-1,P=0.019]. Conclusions Most patients with IgA nephropathy present disappearance of blood pressure circadian rhythm,even among those at an early stage or without hypertension.The loss of blood pressure rhythm may be associated with a rapid renal function decline rate in those with hypertension.

Objective To evaluate the advantages of cytomegalovirus (CMV) real-time PCR, to monitor CMV infection in a population of transplantation recipients in comparison with the qualitative PCR method.Methods 150 plasma samples and leukocytes samples collected from 59 bone marrow transplant recipients and 9 liver transplant recipients were tested by qualitative CMV PCR assay in parallel; Real-time CMV PCR using Roche Light Cycler was performed with 150 plasma samples and 54 control plasma samples.Results Using real-time PCR as the reference standard, the sensitivity and specificity of the qualitative CMV PCR assay with leukocytes samples were 62.5% and 95.5%, with plasma samples were 57.5% and 99.1% respectively. The recipients with the level of CMV DNA over 5?10~3 copies/ml by real-time PCR had higher percentage of developing CMV disease than those below 10~3 copies/ml.Conclusion The quantitative detection of CMV DNA by real-time PCR with plasma is a rapid, specific and sensitive method to monitor CMV infection in patients after transplantation and to guide antivirus therapy.

0.05).The results of Western blotting and immunohistochemical method showed that HO-1 protein expression increased in DOX group and DOX-IR group,and was negative in normal group.More distruction of ultrastructural changes of hepatic cells in IR group was found than in DOX-IR group by transmission electron microscope.Conclusion Doxorubicin pretreatment could protect the liver from ischemia-reperfusion injury,which may be related to HO-1 expression induced by doxorubicin,low dosage of doxorubicin does little harm to rat liver.

Objective:To explore the effectiveness and complications of non-incision removal of tunneled cuffed catheter (TCC).Methods:The clinical characteristics, surgical plans and complications of patients with TCC removal in the Renal Division of Peking University First Hospital from January 1, 2015 to December 31, 2020 were collected and analyzed retrospectively. The patients were divided into non-incision removal group and traditional incision removal group. The clinical characteristics, procedure success rate, procedural duration and complications were compared between the two groups.Results:A total of 349 patients were included in this study, for whom 368 catheter removal procedures were performed, including 286 procedures in the non-incision removal group, 75 procedures in the traditional incision removal group, and 7 procedures without records of surgical plans. There was no significant difference in age, sex, basic kidney diseases and catheter remaining time and location between the two groups (all P>0.05). Two procedures in the non-incision removal group and 1 procedure in the traditional incision removal group failed respectively, and there was no significant difference in the procedure success rate between the two groups (99.3% vs 98.7%, χ2=0.290, P=0.590). The procedural duration in the non-incision removal group was lower than that in the traditional incision removal group [(5.36±1.70) min vs (17.55±3.28) min, t=44.198, P<0.001]. Among the patients who needed TCC exchange, there was no significant difference in the selection of new catheter position between the two groups ( P=0.330). In terms of complications, there were 2 procedures of local hematoma in the non-incision removal group and 1 procedure of infection in the traditional incision removal group, and there was no severe complication in both groups. Conclusions:There was no significant difference in the procedural success rate and complications between non-incision removal group and traditional incision removal group, and non-incision procedure may be superior in reducing the procedure duration and harm less to the patients. Non-incision procedure is a safe and effective method to remove TCC.
