Objective To investigate the risk factors of thrombopenia(TP)in septic patients complicated with acute kidney injury (AKI).Methods Two hundred and sixty five septic patients complicated with AKI admitted in Intensive Care Unit ICU of Zhejiang Provincial People''s Hospital during January 2012 and December 2016 were enrolled in the study.The clinical data, results of laboratory tests, Acute Physiology and Chronic Health Evaluation (APACHEII) scores, Sequential Organ Failure Assessment (SOFA) scores, therapeutic intervention, and 28-day mortality were documented.Among 265 patients, TP occurred within 7 days in 112 cases (TP group) and did not occur in 153 cases (non-TP group).Multivariable Logistic regression analysis was performed to analyze the risk factors of TP.Results The 28-day mortality rate in TP group was higher in TP group than that in non-TP group (47.3% vs.33.3%, χ2=5.307,P<0.05).Univariate analysis showed that age, C-reactive protein (CRP), procalcitonin (PCT) and APACHEII score, SOFA score, continuous renal replacement therapy (CRRT), heparin anticoagulation, shock, usage of linezolid and bloodstream infections were associated with TP in septic patients with AKI(all P<0.05).Multivariable Logistic regression analysis showed that age≥65 (OR=4.53, 95%CI 1.23-9.24,P<0.05), CRRT(OR=5.24,95%CI 2.14-14.56,P<0.01), heparin anticoagulation(OR=4.56,95%CI 2.13-8.46,P<0.01), usage of linezolid(OR=2.35,95%CI 1.25-5.24,P<0.01), shock(OR=2.15,95%CI 1.03-4.96,P<0.01)and bloodstream infections(OR=4.26,95%CI 1.36-12.48,P<0.01)were independent risk factors for septic patients with TP.Conclusion For septic patients with AKI having these risk factors, the platelet counts should be closely monitored, and intervention measures should be given to reduce the occurrence of TP.

Objective:To retrospectively investigate the efficiency of Jinlong capsule combined with transarterial chemoemboli-zation for the treatment of advanced pancreatic carcinoma. Methods: Sixty advanced pancreatic carcinoma patients between January 2009 and May 2013 were randomly assigned into the experimental group (n=30, Jinlong capsule combined with transarterial chemoem-bolization) and the control group (n=30, transarterial chemoembolization). Both groups were subjected to superselective pancreas artery chemotherapy with GEMZAR at a dose of 1.0 g/m2. Results:The overall response rate (CR+PR) was 53.3%and the control rate was 70%(CR+PR+SD) (CR 0, PR 16, SD 5) in the experimental group, whereas those in the control group were 36.7%and 56.7%(CR 0, PR 11, SD 6), respectively. The short-term therapeutic efficacy was higher in the experimental group than in the control group (P<0.05). No significant difference in adverse reactions, including digestive reactions and myelosuppression, almost I-II degree, was observed be-tween the two groups (P>0.05). No significant difference in the Karnofsky performance status was observed between the two groups af-ter the treatment (P<0.05). The 24-month survival rate of the experimental group was 50.0%, whereas that of the control group was 33.3%(P<0.05). Conclusion:The application of Jinlong capsule combined with transarterial chemoembolization for the treatment of advanced pancreatic carcinoma showed good clinical effects. The patients also showed good tolerance to this treatment.

Objective To investigate the roles of integrin ανβ6 in the invasion of colon cancer cells and its molecular mechanisms for regulation of the extracellular matrix (ECM) degradation.Methods The RNA interfering technique was used to downregulate the expression of ανβ6 in colon cancer cells. The expression of ανβ6 in transfected cells was determined by RT-PCR and Western blot.The cell invasive capacity was evaluated by reconstituted basement membrane invasion assay. Western blot and gelatin zymography were used to determine whether the reduced αvβ6 expression affects extracellular signal-regulated kinase (ERK), P-ERK, urokinase-type plasminogen activator (uPA) and matrix metalloproteinases (MMPs) expressions. [3H]-labelled type Ⅳ collagen degradation assay was performed to asess if supression of integrin ανβ6 inhibits extracellular matrix degradation.Results Specific siRNA inhibited the expression of ανβ6 in both the protein and mRNA levels in HT29 cells. Down regulation of integrin ανβ6 inhibited ERK, P-ERK1/2 expressions, and the secretion of uPA. pro-MMP-9 and pro-MMP-2 in tumor conditioned medium. Supression of integrin ανβ6 inhibited MAPK dependent [3H]-labelled type Ⅳ collagen degradation. Conclusions These data in our study demonstrats that integrin ανβ6 plays important roles in the invasion of colon cancer cells. The ανβ6 regulates the secretion levels of uPA, pro-MMP-9, pro-MMP-2 and the ECM degradation through the MAPK pathway.

Objective To investigate the metabolite changes in systemic lupus erythematosus (SLE) patients with and without neuropsychiatric symptoms using magnetic resonance spectroscopy (MRS) and explore the associations between image findings and clinical variables. Methods Twenty-two SLE patients with neuropsychiatric symptoms (NPSLE), twenty-one SLE patients without neuropsychiatric symptoms (non-NPSLE) and twenty healthy controls (HCs) underwent routine MRI scan and multivoxel magnetic reson-ance spectroscopy (MVS). The absolute metabolite concentrations were measured bilaterally in the posterior cingulate gyrus (PCG), dorsal thalamus (DT), lentiform nucleus (LN) and posterior paratrigonal white matter (PWM) using LCModel and SAGE software. The relationships between metabolite con-centrations and cognitive function scores were analyzed by Spearman rank correlation. Single-factor Chi-square analysis and t-test were used for analysis. Results ① Compared to control subjects, NPSLE patients had significantly lower N-acetylaspartate (NAA) values in bilateral PCG and DT, with the mean differences of -1.504 [95% confidence interval ( CI) (-2.335, -0.672), P=0.001], -1.460 [95%CI (-2.349, -0.570), P=0.002], -1.259 [95%CI (-1.894, -0.625), P=0.000] and -1.022[95%CI (-1.688, -0.356), P=0.003] for RPCG, LPCG, RDT and LDT, respectively. The concentration of total creatinine were observed to decline in RPCG and RDT, with the mean differences of-1.094 [95%CI (-1.845, -0.342), P=0.003], -0.955 [95%CI (-1.630, -0.280), P=0.006], -1.259 [95%CI (-1.894,-0.625), P=0.006] respectively. Glutamine and glutamate-values decreased significantly in RDT [mean difference=-2.586, 95%CI (-4.139, -1.033), P=0.002]. ② Compared to non-NPSLE patients, NPSLE patients had a lower NAA level in LPCG [mean difference=-1.256, 95%CI (-2.146, -0.367), P=0.006]. Positive correlations between mini-mental state examination scores [RPCG: rs=0.312, P<0.05; LPCG: rs=0.355, P<0.01], Montreal cognitive assessment scores (RPCG: rs=0.362, P<0.01; LPCG: rs=0.285, P<0.05) and NAA values in bilateral PCG were detected. Conclusion Both NPSLE and non-NPSLE patients may have metabolite dysfun-ctions in different brain regions. The cognitive disorder in SLE patients may be interpreted by neuronic damage of PCG.

Objective To evaluate the absolute quantification of brain metabolites concentrations using external standard MRS in acute hypoxia ischemia encephalopathy (HIE) piglet model. Method Eight 7-day-old healthy piglets were subjected to insult of hypoxia ischemia (HI). The animals and an external standard phantom containing detectable metabolites of known concentrations were studied on a 1.5 T GE Signa scanner. The single-voxel proton magnetic resonance spectroscopy (1H-MRS) data were processed using LCModel software, and the quantification of N-acetylaspartate ( NAA), creatine (Cr) and lactate (Lac) were accomplished. Multivariate analysis of variance was performed to compare the NAA, Cr, Lac concentration differences in the brains of piglets pre- and post-HI (0h). In addition, the dynamic changes of brain metabolites concentrations of 2 HIE piglets were observed at the time points of 0 h and 2 h. Results One piglet was excluded because it was over anesthetized to death. Seven piglets' data were analyzed. The concentrations of NAA pre- and post-HI were ( 6. 86 ± 0. 49 ) mmol/kg and ( 5.73 ± 0. 88 ) mmol/kg respectively, they were ( 4. 65 ± 0. 73 ) mmol/kg and ( 4. 40 ± 0. 80 ) mmol/kg for Cr; and were 0. 00 mmol/kg and (0. 43 ± 0. 39) mmol/kg for Lac. After HI, decreased NAA concentration immediately was observed, and it was of statistical significance ( F = 8. 608, P = 0. 013 ). The concentration of Cr was insignificantly decreased ( F = 0. 379, P = 0. 550). The concentration of Lac was increased, and the difference was of statistical significance ( F = 8. 600 ,P = 0. 013 ). Dynamic observation showed a Lac peak immediately after HI and it decreased after 2 h post-HI. Conclusions External standard MRS using LCModel has great value in the quantitative analysis of brain metabolites. The changes of NAA and Lac concentrations are sensitive to reflect the early metabolic change of acute HIE.

Objective To investigate the effect of geraniin on expression of Wnt3a protein and mRNA in bone marrow stromal cell (BMSC) from osteoporotic rats. Methods The model of osteoporosis (OP) was duplicated by ovariectomy in rats. BMSCs were isolated and cultured. BMSCs from shamed rats were routinly cultured and taken as normal control, and BMSCs from OP rats were divided into model group, 1μmol/L simvastatin positive group, and geraniin group (0.01, 0.1, 1, 10, 100 μmol/L), respectively. The methods of realtime-PCR and western blot were used to assay the protein and mRNA expression of wnt3a, respectively.Results As compared with normal control group, the protein and mRNA expression of wnt3a in model group were significantly suppressed;Compared with model group, 1 μmol/L simvastatin, and 0.1, 1, 10 and 100 μmol/L geraniin significantly increased the expression of wnt3a protein and mRNA. Conclusion It is suggested that geraniin activates wnt/β-catenin pathway though increasing the expression of signaling protein wnt 3a in BMSCs from OP rats. It would be beneficial to osteogenic differentiation of BMSCs and osteogenesis.

Objective To discuss the effects of pressure control (PC) and positive end-expiratory pressure (PEEP) incremental method lung recruitment maneuver (RM) on haemodynamics in piglets with acute lung injury (ALI) induced by paraquat (PQ) poisoning. Methods The ALI/acute respiratory distress syndrome (ARDS) model was reproduced by intraperitoneal injection of 20% PQ (20 mL) in 10 healthy female piglets, and they were randomly divided into PC lung RM group (RM1 group) and PEEP incremental method lung RM group (RM2 group), with 5 piglets in each group. Heart rate (HR), mean arterial pressure (MAP), and cardiac index (CI) were monitored by pulse-indicated continuous cardiac output (PiCCO) monitoring before model reproduction (baseline), on the time of successfully set up of model and at 5, 15 and 30 minutes after RM. At the same time the arterial partial pressure of oxygen (PaO2) and arterial partial pressure of carbon dioxide (PaCO2) were recorded, and oxygenation index was calculated. Lung tissues were collected before model reproduction, on the time of successfully set up of model, and at 30 minutes after RM respectively, and pulmonary pathology changes were observed after hematoxylin and eosin (HE) staining under light microscopy. Results The HR, MAP, and PaCO2 on the time of successfully set up of model in both groups were increased obviously while CI, PaO2, and oxygenation index were decreased obviously as compared with those at baseline, all of which conformed to the expression of ALI/ARDS. With RM time extended, the HR in both groups was declined while MAP and CI were increased gradually. The HR and MAP at 5 minutes after RM of RM1 group were significantly lower than those of the RM2 group [HR (bpm): 126.8±5.2 vs. 134.0±3.8, MAP (mmHg, 1 mmHg = 0.133 kPa): 98.4±3.3 vs. 102.8±2.6, both P < 0.05]. The CI at 5 minutes and 15 minutes after RM of RM1 group was significantly higher than that of the RM2 group (mL·s-1·m-2: 56.7±5.0 vs. 46.7±6.7, 65.0±5.0 vs. 56.7±5.0, both P < 0.05). PaO2 and oxygenation index at 5 minutes after RM in both groups were significantly higher than those on the time of sucessfully set up of model. The PaO2 and oxygenation index were gradually decreased, and PaCO2 was increased with RM time extended, but no statistically significant differences at all time points were found between the two groups (all P > 0.05). The lung tissue in both groups showed a variety of pathological changes at 30 minutes after RM. The main performances were the loss of alveolar epithelial cells, the further wideness of alveolar interval and the distension of alveolar, and the part breakage of alveolar interval. The wideness of alveolar interval was more significant in RM2 group than that of RM1 group, and alveolar cleft was more common too. Conclusion Both PC and PEEP incremental method lung RM can improve the oxygenation of the piglets with ALI/ARDS induced by PQ, and the PC lung RM has less impact on haemodynamics.
