Objective To investigate the correlation between the baseline serum caveolin-1 (Cav-1) levels and the clinical outcome in patients with acute ischemic stroke at day 90 after onset. Methods Consecutive patients with acute ischemic stroke treated in hospital were enrolled. The Cav-1 levels were measured by the enzyme-linked immunosorbent assay. Functional outcomes were assessed at day 90 after onset using the modified Rankin Scale (mRS), and mRS 0-2 was defined as good outcome. The demographic and clinical characteristics of the good outcome group and the poor outcome group were compared. Multivariate logistic regression analysis was used to identify the correlation between the low serum Cav-1 levels and the poor outcome at day 90 after onset. Results A total of 169 patients with acute ischemic stroke were included in the analysis, including 116 males (68. 5% ). Their age ranged from 50 to 83 years (mean, 63. 4 ± 9. 1). The mean serum Cav-1 level was 5. 483 ± 2. 617 ng/ml. Eighty-three-patients (49. 1% ) were in the good outcome group and 86 (50. 9% ) were in the poor outcome group. Univariate analysis showed that the proportions of patients in subcortical infarct (60. 5% vs. 43. 4% ; χ2 = 4. 944, P = 0. 026) and diffusion-weighted imaging-Alberta Stroke Program Early CT Score, (DWI-ASPECT) ≤7 (58. 1% vs. 40. 9% ; χ2 = 4. 984, P = 0. 026), as well as age (65. 5 ± 8. 9 years vs. 61. 2 ± 10. 7 years; t = 2. 793, P =0. 006), baseline systolic blood pressure level (140. 6 ± 17. 2 mmHg vs. 134. 9 ± 13. 4 mmHg; t = 2. 368, P = 0. 019; 1 mmHg = 0. 133 kPa), and National Institutes of Health Stroke Scale (NIHSS) score (4. 8 ± 3. 4 vs. 3. 9 ± 2. 2; t = 2. 211, P = 0. 036) were significantly higher than those of the good outcome group, and the serum Cav-1 level was significantly lower than that of the good outcome group (4. 9 ± 2. 3 ng/ml vs. 6. 1 ± 2. 1 ng/ml; t = 2. 977, P = 0. 003). After adjusting for the related confounding factors, multivariate logistic regression analysis showed that the low Cav-1 level was an independent predictor of poor outcome at day 90 in patients with acute ischemic stroke (odd ratio, 1. 157, 95% confidence interval 1. 016-1. 319;P = 0. 028). Conclusion The low serum Cav-1 level is an independent predictor of poor outcome in patients with acute ischemic stroke.

Purpose:In order to explore the feasibility and efficacy of acupoint-injecting method for marrow inhibition caused by chemical medications. Methods: 110 cases of malignant tumors in the phase of marrow inhibition after arterial chemotherapy were treated by puncturing the acupoints, Zusanli (ST 36), Sanyinjiao (SP 6), Xuehai (SP 10) and Qihai (CV 6) plus injection of 5 mg dexamethasone. Results: Acupuncture treatment and acupuncture plus injection of medications can both effectively improve marrow inhibition after chemotherapy, and the therapeutic effect was better in the group by acupuncture plus acupoint-injecting method. Conclusion: Acupuncture can effectively stimulate the acute and short-term marrow inhibition caused by chemical medications, and acupuncture plus acupoint-injecting method can effectively shorten the treatment time and the lower hemogram phase of peripheral blood. The combination of two therapeutic methods can have remarkable cooperative effect and reduce the medical expenses.

Since intra-arterial chemotherapy with the help of implantation of port-catheter system (PCS) was first used in the surgical field in 1981, PCS has been widely employed in the field of interventional radiology. Intra-arterial chemotherapy by implantation of PCS has some certain advantages such as minimal invasion, no need of general anesthesia, etc. Ten randomized clinic trails have been already reported, which indicate that intra- arterial chemotherapy with PCS is obviously superior to systemic chemotherapy in treating hepatic metastasis form colorectal cancer. As for the treatment of advanced biliary tract cancer, pancreatic carcinoma and hepatocellular carcinoma, the relevant reports can be found only in several phaseⅠ/Ⅱclinical trials or in some retrospective cohort studies. This paper aims to make a comprehensive review about the indications, clinical applications and complications of PCS in treating abdominal tumors in order to improve the clinical practice.

Fortyfour male Kunming mice, weighing 20-25g. were used. The HpD was injected (10mg/kg) into the caudal vein of 32 mice individually. After 48 hours, the kidneys were radiated directly by the dye-laser for 10 minutes (630nm, 250-300J/cm~2). Then, the kidneys were observed at different times. 12 normal male mice served as control. The experiment demonstrated that when HpD was activated by laser, it could produce the necrotic effect on the renal tissues. The different structures of the kidney showed different susceptibility to HpD-laser. The proximal convoluted tubules and capillaries were injured earlier than the distal convoluted tubules and the collecting tubules. The first morphologic changes observed electron microscopically were the swelling of mitochondria and the formation of vesicles on the cell membrane. Finally, they were completely disrupted. The damages of lysosomes, endoplasmic reticula, ribosomes and cell nucleus followed. The activity of some enzymes in the kidney were inhibited. The sequence of the extents of the enzymes being inhibited was AkP, AcP, Cytox, SDH. The mucopolysaccharides ran off the brush border in proximal convoluted tubules. The results of this study suggested that the various susceptibilities to HpD-laser are chiefly due to the different structures and their functional conditions in the kidney. The main photodynamic effect is presented as the injury of the membrane system of the cell.

Objective To investigate the metabolites of serum samples from liver cirrhotic patients with or without minimal hepatic encephalopathy,and even overt hepatic encephalopathy,then to find out diagnostic markers for minimal hepatic encephalopathy.Methods High performance liquid chromatography-orbit trap mass spectrometry (UPLC/LTQ-Orbit trap MS) technology was applied to analyze the serum metabolites from 38 patients of liver cirrhosiswith hepatitis B and 33 healthy volunteers.Results The serum metabolites of patients with simple liver cirrhosis were different from those of patients with minimal or overt hepatic encephalopathy.The serum metabolites of patients with minimal hepatic encephalopathy was mostly similar with those of overt hepatic encephalopathy patients.Arginase,L-tyrosine,glutamic acid,two L-phenylalanine peptide,homovanillic acid,omithine,L-serine were increased in patients with minimal or overt hepatic encephalopathy,and hypoxanthine decreased in patients with minimal or overt hepatic encephalopathy patients.Conclusions The serum metabolites of patients with minimal hepatic encephalopathy are mostly similar to those of patients with overt hepatic encephalopathy.Arginase,L-tyrosine,glutamic acid,two L-phenylalanine peptide,homovanillic acid,ornithine,L-serine maybe the early metabolites biomarkers to diagnose minimal hepatic encephalopathy.Hypoxanthine is likely to be an effective complement to treat patients with hepatic encephalopathy.

Objective To investigate the calcium signal transduction pathway in hippocampal neurons of mice with vascular dementia (VaD) and the intervention effect of dihydroergocriptine (DHE). Methods The mice were subjected for ischemia-reperfusion repeatedly on bilateral common carotid arteries by knots to establish the VaD models. Animals with sham-operation were taken as control group. The treating group was administered with DHE after the establishment of VaD model. The behavior changes were observed through the step-down avoidance test and water maze test on the 29th and 30th days after operation. The resting 〔Ca 2+〕 i level of hippocampal neurons was evaluated by laser scanning confocal microscopy. RT-PCR technique was used to measure mRNA expression of CaM an CaMPKⅡ in hippocampal neurons. Results The resting 〔Ca 2+〕 i level in model group(43.50?3.00) was significantly higher than those in the sham-operation group (25.50?3.50) (P

Objective To investigate the effects and the possible mechanisms of nerve growth factor (NGF) on serum levels of vascular endothelial growth factor (VEGF) and stromal cell-derived factor 1 (SDF-1) protein expression in rats with focal cerebral ischemia.Methods Male Sprague-Dawley rats weighting 200 ～ 250 g were subjected to middle cerebral occlusion (MCAO).MCAO rats were randomly divided into NGF group,saline control group and NGF+PI3K antagonist group (n =12).The neurological function was evaluated on the 4th,7th day after MCAO,and the serum levels of VEGF and SDF-1 protein were measured by ELISA.Results The neurological function was better in rats of the NGF group than those of the saline control group and NGF+PI3K antagonist on the 4th,7th day after MCAO (P ＜ 0.05).The serum levels of VEGF and SDF-1 protein of the NGF group was significantly higher than that of the saline control group and NGF+PI3K antagonist group on the 4th day after MCAO (P ＜ 0.05).Conclusions Treatment with NGF may improve neurological function of rats with focal cerebral ischemia,and upregulate serum levels of VEGF and SDF-1 protein expression.PI3K/AKT signal pathway may have attended the above regulation.

Objective To investigate the changes of serum miR-21 expression level in patients with HCC before and after transcatheter arterial chemoembolization (TACE) and to discuss its clinical significance. Methods Before and after TACE the levels of serum miR-21 in 42 patients with HCC and 42 healthy subjects were determined by reverse transcriptase quantitative PCR (RT-PCR), and the levels of serum AFP were also estimated by enzyme-linked immunosorbent assay (ELISA). The results were analyzed. Results The serum miR-21 level in patients with HCC was (12.9 ± 3.5) times of that in normal subjects(t=19.430 7, P < 0.01). One month after TACE, the serum miR-21 level became (7.2 ± 1.7) times of that of normal reference value, which was remarkably lower than that obtained before the treatment (t=9.493 7, P<0.01). The serum miR-21 level was closely correlated with the tumor size, the presence of tumor thrombus and HBV infection. One month after TACE the serum miR-21 levels in patient groups showing partial response, stable disease and progressive disease were (4.0 ± 0.3), (6.0 ± 1.5) and (8.6 ± 1.5) times, respectively, of that of normal reference value, and statistically significant difference existed between each other among the three groups (F=38.168, P=0.000). ROC-AUC value of MiR-21 in diagnosing HCC was 0.910 ± 0.041, which was significantly higher than that of AFP (0.860 ± 0.037, t=6.3042, P<0.01). The specificity of miR-21 in detecting HCC was 88.1%, which was remarkably higher than that of AFP (69%, χ2= 4.5253, P = 0.033).Conclusion After TACE the serum MiR-21 level in HCC patients is significantly decreased, which is very helpful in predicting the therapeutic efficacy of TACE. Therefore, MiR- 21 can be regarded as a potential molecular marker of HCC.

Objective:The present study aimed to conduct a clinical analysis of nosocomial infections in hospitalized cancer pa-tients and propose effective precautionary measures. Methods:We retrospectively analyzed 56,430 cases of discharges from the Cancer Institute and Hospital of Tianjin Medical University between January and December 2012. Results:Among 825 cases, the rate of noso-comial infections was 1.46%;46.42%of the patients aged>60 years. The highest infection rate was observed in the Medical Depart-ment of Stomach Cancer. The highest composing rate was recorded in the Department of Hepatobiliary Cancer. The major pathogenic bacteria were Gram-negative bacilli;fungal infections were relatively rare. The most vulnerable body parts were the abdomen and diges-tive tract, which were mainly infected by pathogenic Escherichia coli. Conclusion:Healthcare workers should consider the importance of influencing factors and take precautionary measures to reduce the rate of nosocomial infections in cancer patients.
