Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.

OBJECTIVETo identify the risk factors of hepatorenal syndrome in patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure(ACLF).

METHODSA total of 726 hospitalized patients with HBV-ACLF were retrospectively analyzed. Data of demographic and clinical parameters (sex, age, family history, and presence of liver cirrhosis and diabetes), common complications (spontaneous bacterial peritonitis, pulmonary infection, hepatic encephalopathy, and upper gastrointestinal hemorrhage), and baseline biochemical parameters (albumin, globulin, total bilirubin, direct bilirubin, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, cholesterol, cholinesterase, K+, Na+, plasma thromboplastin antecedent, alpha-fetoprotein, HBV DNA, white blood cell count, hemoglobin, and platelet count) were collected from the medical records database. Univariate and multiple regression analyses were performed to determine the risk factors of hepatorenal syndrome.

RESULTSMultiple logistic regression analysis indicated that upper gastrointestinal hemorrhage [risk (R) = 1.313, relative hazard (RH) = 3.716, 95% confidence interval (CI): 2.156-6.404], hepatic encephalopathy (R = 1.120, RH = 3.065, 95% CI: 1.900-4.945), spontaneous bacterial peritonitis (R = 1.005, RH = 2.733, 95% CI: 1.379-5.417), pulmonary infection (R = 1.051, RH = 2.862, 95% CI: 1.783-4.592), and white blood cell count (R = 0.056, RH = 1.058, 95% CI: 1.010-1.107) were independent risk factors for hepatorenal syndrome development in patients with HBV-ACLF.

CONCLUSIONSeveral risk factors were significantly associated with the development of hepatorenal syndrome in HBV-ACLF, including upper gastrointestinal hemorrhage, hepatic encephalopathy, spontaneous bacterial peritonitis, pulmonary infection, and elevated white blood cell count.

OBJECTIVETo investigate the impact of early rapid virological response on the outcomes of hepatitis B associated acute on chronic liver failure during antiviral treatment.

METHODS106 acute on chronic liver failure patients in our hospital from January 2008 to July 2010 were enrolled in present study retrospectively. Besides internal medicine therapy, all patients received lamivudine (100 mg/d) or entecavir (0.5 mg/d) treatment. The profile of liver biochemistry, prothrombin time activity and viral load were detected at baseline and week 4, respectively. The patients were divided into HBV DNA negative group and HBV DNA positive group according to the viral load at week 4. The clinical features and treatment outcomes were compared between groups. Frequency variables were compared by x2 test or Fisher's exact test. Continuous variables were compared using independent samples T-test. The factors that impact on the treatment outcomes were determined using stepwise multivariate logistic regression analysis.

RESULTSAt the week 4, the TBil and PTA in HBV DNA positive group [(261.6+/-205.6)mumol/L and 44.7%+/-19.7%, respectively] were significantly different from those in HBV DNA negative group [(160.1+/-173.4) mumol/L and 56.8%+/-23.1%, respectively] ( t = 2.190 and -2.077, respectively, P less than 0.05). The non-effective rate of HBVDNA positive group (50%, 9/18) was significantly higher than that of HBV DNA negative group (14.8%, 13/88) (x2 = 9.235, P less than 0.01). By using stepwise multivariate logistic regression analysis, the disease stage and HBV DNA undetectable at week 4 were the independent factor. The OR values of disease stage and HBV DNA undetectable were 6.559 and 0.209, respectively, and 95% CI was 2.316~18.576 and 0.058~0.747, respectively.

CONCLUSIONThe rapid suppression of viral load by nucleotide analogue may improve the efficacy of hepatitis B associated acute on chronic liver failure treatment. The early rapid virological response within first 4 weeks may contribute to the prediction of the treatment outcomes.

OBJECTIVETo investigate the clinical characteristics of and factors related to relapse in chronic hepatitis B (CHB) patients who had previously achieved cessation criteria and had been withdrawn from nucleoside analogues treatment.

METHODSSixty CHB patients who experienced relapse after nucleoside analogues withdrawal based on cessation criteria were enrolled in the study retrospectively. Each patient's data on biochemical, serological and viral characteristics corresponding to baseline (treatment initiation), withdrawal and relapse were collected. COX proportional hazard modeling was used to evaluate the factors related to relapse.

RESULTSThe hepatitis B e antigen (HBeAg)-positive and -negative patients had similar median antiviral treatment times (38 months (range: 24 - 80) vs. 35 months (30 - 60); Z = -1.313, P more than 0.05). For all patients, the median follow-up time was 12 months (2 - 72), during which 49 (81.7%) patients developed virological breakthrough and 17 (28.3%) developed HBeAg recurrence. The patients who experienced virological breakthrough or HBeAg recurrence had significantly higher baseline levels of HBV DNA than those patients who remained disease-free (t = 2.15 and -2.54 respectively; P less than 0.05). The median relapse time of the HBeAg-positive patients was significantly longer than that of the HBeAg-negative patients (14 months (3 - 72) vs. 6 months (3 - 36); Chi-square test = 7.045, P less than 0.01). HBeAg status at baseline was identified as an independent factor associated with relapse (relative risk = 1.937, 95% confidence interval = 1.14-3.28, P less than 0.05).

CONCLUSIONHBeAg-positive and-negative patients showed distinct clinical characteristics of relapse, with the latter being more prone to relapse soon after nucleoside analogues withdrawal. Prolonging the treatment course may be beneficial to HBeAg-negative patients, even if cessation criteria are achieved.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
