Objective To investigate the effects and mechanisms of bone marrow mesenchymal stem cells (BMSCs) on pancreatic fibrosis in rats of chronic pancreatitis. Methods Thirty healthy male SD rats were randomly divided into three groups:control group, model group and transplanted group (n=10 for each group). Chronic pancratitis rat model was induced by retrograde injection of oleic acid into the biliopancreatic duct. The sham operation group was treated only with solvent. Transplanted group was given BMSCs through caudal vein injection at 1 week and 5 weeks after the model induction. All rats were weighed at 1 week, 4 weeks and 8 weeks in three groups. After 8-week feeding,pancreatic tissues were harvested for HE and picric-sirius staining. The contents of transforming growth factorβ1 (TGF-β1), typeⅠcollagen and typeⅢcollagen were detcted by using ELISA. Results Compared with the control group, the weights of rats were decreased at 4 weeks and 8 weeks in model group and transplantated group (P<0.05). There were no significant differences in body weights between model group and transplantated group (P>0.05). The pancreatic fibrosis score and pathological injury were ameliorated signicantly in transplanted group. The contents of TGF-β1, typeⅠcollagen and typeⅢcollagen in pancreas were increased in model group than those of control group and transplanted group (P<0.05). Conclusion BMSCs transplantation can reduce the collagen secretion and reduce the degree of pancreatic fibrosis in rats with chronic pancreatitis, which may be related to the inhibition of the release of TGF-β1.

Objective To explore the application value of pulse induced contour cardiac output (PiCCO) monitoring in diagnosis and treatment of patients with neurogenic pulmonary edema (NPE).Methods With review of literature, the data of 4 patients of severe neurological disease complicated by NPE admitted into Department of Critical Care Medicine of Huangshan People's Hospital Affiliated to Wannan Medical College from 2011 to 2013 were retrospectively analyzed and discussed in their PiCCO hemodynamic characteristics and processes of treatment.Results The PiCCO of 4 patients with NPE showed that the extravascular lung water index (EVLWI) was increased significantly (EVLWI was 12 - 42 mL/kg on admission and 10 - 22 mL/kg after hospitalization for 24 hours), all revealing a high permeability pulmonary edema type. The capacity balance of the first 24 hours in the 4 cases was all of positive balance (+1 130, +1 200, +1 750, +1 120 mL respectively). In the treatment, the supplementary colloid was strengthened, the vasoactive drugs such as, dopamine, dobutamine, milrinone, etc were applied to improve the circulatory oxygenation, then the EVLWI was declined; finally the disease situation in 3 cases was improved and one died.Conclusions The clinical diagnosis and treatment of NPE is complex, and many contradictions appear in the therapeutic course. PiCCO monitoring is valuable in early diagnosis, identification of pulmonary edema type, guidance in fluid supplement and vascular active drug application, and assessment of disease severity and prognosis.

ObjectiveTo explore the risk factors of the occurrence of acute kidney injury (AKI) in critically ill patients, and to investigate the effect of hydroxyethyl starch (HES) on renal function in these patients.Methods A prospective investigation was conducted. Critically ill patients admitted to Department of Critical Care Medicine of People's Hospital of Huangshan, Wannan Medical College from March 2012 to October 2013 were enrolled. For all the patients under observation, the following data were collected: demography, comorbidities, clinical presentation, severity of illness, and the use of blood product and drugs. All patients were divided into AKI group and non-AKI group by means of Acute Kidney Injury Network (AKIN) criteria, then the risk factors of AKI were investigated by means of univariate and multivariate logistic regression analysis. The effect of HES 130/0.4 administration on renal function in critically ill patients was evaluated.Results 314 patients were enrolled for study out of 1 152 patients admitted. Among these patients enrolled, 89 of them were found to suffer from AKI. AKI was classified as stage 1 in 59 patients, stage 2 in 19 patients, and stage 3 in 11 patients. It was shown by the univariate analysis that 12 variables were the risk factors of AKI, including age, hypertension, diabetes mellitus, acute physiology and chronic health evaluationⅡ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, coagulation SOFA score, neurological SOFA score, cardiovascular SOFA score, blood pH on intensive care unit (ICU) admission, blood glucose on ICU admission, accumulating dose of HES, and presence of shock (P< 0.05 orP< 0.01). However, HES administration and daily maximum dose of HES were not the risk factors of AKI in critically ill patients (bothP> 0.05). Using the multivariate logistic regression analysis, it was shown that total SOFA score [odds ratio (OR) = 1.20, 95% confidence interval (95%CI) = 1.09-1.32,P< 0.001], hypertension (OR = 2.44, 95%CI = 1.22-4.89,P= 0.012), blood glucose level on ICU admission (OR= 1.85, 95%CI = 1.32-2.59,P< 0.001), and presence of shock (OR = 3.81, 95%CI = 1.93-7.53,P< 0.001) were independent predictors of AKI in critically ill patients, however, the cumulative dose of HES was not independent risk factor for AKI (OR = 0.77, 95%CI = 0.68-0.87,P< 0.001).Conclusions Total SOFA score, hypertension, blood glucose level on ICU admission, and presence of shock were independent risk factors for AKI in critically ill patients. HES administration may not be a causative factor of an increased risk of AKI in the ICU.
