A strain of resistance to copper and cadmium with high concentration, named NTG-01, was isolated from soils of DaYe county mineral area in HuBei province. It can resist copper of 4.5mmol/L and cadmium of 2mmol/L , so we can say that it is a important strain used to study the resistance mechanism of copper and cadmium. A series of morphological and biochemical characteristics and sequences analysis of 16S rDNA reveal that it belongs to the bacteria and is gram negative, short rod, flagella around, the size of bacteria is about 0.8?m?2.0?m , V-P result shows positive, methyl-red result displays negative, and glucose can be utilized to produce acid and gas; In addition to, we find that it has the percent 99 homologous to Enterobacteraerogenes by 16S rDNA sequences BLAST analysis, plus the results of morphological and biochemical parameters, it belongs to Enterobacteraerogenes. We can conclude that NTG-01 has higher resistance to many different heavy metals by measuring MICs values of nine heavy metals at last.

Objective To assess retinal arteriole stenosis in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and to evaluate the relationship between retinal arteriole stenosis with cranial MRI changes and clinical features. Methods Sixteen CADASIL patients (mean age was (43.4±8.1)years, mean duration was(4.7±3.4)years)and sixteen age matched healthy individuals were enrolled. Mini-Mental State Examination (MMSE) and modified Rankin scale scoring were performed in 16 patients. Cranial MRl with Coulthard scores was assessed on CADASIL patients as well. Retinal examinations for arteriole stenosis were done for each subject. Bivariate correlations (Kendall's tau-b) were used to assess the relationship among the grade of retinal stenosis, MMSE, modified Rankin seale, cranial MRI with Coulthard scores and age. Results Retinal arteriole stenosis presented in 15 cases. in whom 4 cases showed mild arterio-venous nicking. while it only presented in 2 controls. Grade 0.Ⅰ, and Ⅲ of retinal arteriole stenosis are noted in 1/16,4/16,7/16 and 4/16cases respectively. Coulthard scores of cerebral MRl were 6.0.19.0.25.1 and 29.8 respectively from Grade 0 toⅢ of retinal arteriole stenosis. The correlation coefficient of retinal arteriole stenosis and cranial MRI scores was 0.743(P＜0.001＝,MMSE-0.429(P＜0.05＝,modified Rankin scale 0.437(P＞0.05).and age 0.299(P＞0.05).Conclusion Retinal arteriole stenosis is significantly correlated with lesion in cranial MRI and dementia.

The in vitro release behavior, in vivo biodistribution and antitumor activity of N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer-5-fluorouracil conjugates (P-FU) were studied. The in vitro release behavior was evaluated by determining the amount of 5-fluorouracil (5-FU) released from P-FU in mice plasma at 37 degrees C. The in vivo biodistribution and therapeutic evaluation were investigated with Kunming mice bearing hepatoma 22 (H22). The in vitro half-life (t1/2) of P-FU in mice plasma was 32.4 h. It appeared that the circulation life time of the conjugates were 166 times longer than that of 5-FU. The AUC and t1/2 of P-FU in tumor were 3.3 times and 2.3 times more than those of 5-FU, respectively. Therapeutic evaluation also demonstrated that the treatment with P-FU displayed stronger inhibition of the tumor growth when compared with that of 5-FU (P < 0.05). HPMA copolymer is a potential carrier for 5-FU for effective treatment of cancer.

Objective To analyze the dynamic evolution of brain MRI in patients with mitochondrial myopathy,encephalopathy,lactic acidosis,and stroke-like episodes (MELAS) syndrome.Methods A retrospective study was performed on 58 MELAS cases with pathologically and (or) molecularly confirmed diagnosis.MRI were repeated within 60 days after the onset of stroke-like episodes (SLE) and the evolution changes of cerebral lesions were accessed.Brain atrophy index (BAI) was calculated in the remission stage from 31 patients with MELAS,and the correlation between BAI,age and disease duration was analyzed.Results The proportion of lesions expansion,migration and shrink within 30 days after the onset of SLE was 64.1％ (25/39),10.2％ (4/39),17.9％ (7/39),respectively,and 13％ (3/23),21.7％ (5/23),56.5％ (13/23),between 30-60 days after the onset of SLE respectively.In the recovery stage of SLE,the BAI in 31 patients with MELAS was 15.2％ ±2.8％.The correlation coefficient between BAI and the age,total disease course and duration of encephalopathy was 0.329 (P =0.043),0.405 (P =0.012) and 0.649 (P =0.000).Conclusions Brain atrophy in the studied MELAS patients gradually develops and strokelike lesions shrink with progression of the disease.However,the migration of lesions is persistent.

Objective To investigate the cerebral vascular autoregulation in patients with mitochondrial encephalomyopathy with lactic acidosis and strokc-like episodes (MELAS) during the remission of stroke-like episodes,including cerebrovascular CO2 reactivity and vascular endothelial function.Methods Twenty-nine MELAS patients confirmed by genetic analysis were recruited in this study. They underwent the examination at least 2 weeks after the onset of last stroke-like episode.Twenty-eight healthy people were collcctcd as healthy controls. Carotid ultrasound and brain magnetic resonance angiogram (MRA) were done to evaluate the cervical and intracranial appearance of large arteries. Evaluation of vascular autoregulation included: (1) the cerebrovascular CO2 reactivity with breath-holding test by transcranial Doppler and calculating breath holding index (BHI),and ( 2 ) flow-mediatcd dilation ( FMD )and nitroglycerin-mediated dilation with ultrasound assessment of humeral artery.Independent-samples t test was done between the results of two groups.Results Carotid ultrasound and cranial MRA revealed no abnormalities in both MELAS patients and healthy controls.The BHI of MELAS patients was significantly decreased than that of normal controls ( 1.36 ± 0.52 vs 1.81 ±0.26,t =- 3.693,P ＜ 0.01 ),and the FMD of MELAS patients was also significantly lower than that of normal controls (11.0％ ±4.8％ vs 15.8％ ±5.8％,t =-3.390,P ＜0.01).Conclusion The function of vascular autoregulation,including cerebrovascular CO2 reactivity and FMD,is impaired in MELAS patients.

Objective To evaluate the effect of point-of-care hemoglobin/hematocrit (POC HGB/HCT) devices and intraoperative blood salvage on the amount of perioperative allogeneic blood transfusion and blood conservation in clinical practice.Methods A total of 46 378 medical records of 22 selected hospitals were reviewed. The volume of allogeneic red blood cell and plasma, number of patients transfused, number of intraoperative autologous blood salvage, total volume of autologous blood transfusion, and amount of surgery in the year of 2011 and 2013 were tracked. Paired t-test was used in intra-group comparison, while t-test of two isolated samples carried out in inter-group comparison. P<0.05 was defined as statistically significant difference.Results In the hospitals where POC HGB/HCT device was used (n=9), the average allogeneic blood transfusion volume per 100 surgical cases in 2013 was significantly lower than that in 2011 (39.86±20.20 vs. 30.49±17.50 Units, t=3.522, P=0.008). In the hospitals without POC HGB/HCT meter, the index was not significantly different between 2013 and 2011. The average allogeneic blood transfusion volume was significantly reduced in 2013 than in 2011 in the hospitals where intraoperative autologous blood salvage ratio [autologous transfusion volume/(autologous transfusion volume+allogeneic transfusion volume)] was increased (n=12, t=2.290, P=0.042). No significant difference of the above index was found in the hospitals whose autologous transfusion ratio did not grow.Conclusion Intraoperative usage of POC HGB/HCT devices and increasing autologous transfusion ratio could reduce perioperative allogeneic blood transfusion.

Here we report the clinical,radiological and neuropathological findings of a patient with tumor-like inflammatory demyelinating diseases of the central nervous system.The patient was a 51-year-old man with a four-month history of inflammatory pseudotumor and no other significant medical history,who presented to our hospital recurrent relapse numbness and weakness of his right extremities,dysarthria and memory deterioration.Brain magnetic resonance imaging(MRI) showed mass focal lesion in white matter of left parietal lobes.The biopsy showed numerous infiltrating macrophages and lymphocytes within the perivascular.The patient responded clinically to corticosteroid and intravenous immunoglobulin(IVIG) therapy.According to the results of the biopsy and the MRI,a diagnosis of inflammatory pseu-dotumor of the central nervous system was made.The vascular dysfunction may act in the pathogenesis of inflammatory pseudotumor of the central nervous system.

Objective To evaluate the blood supply features and effectiveness of arterial chemoembolization for pedunculated hepatocellular carcinoma.Methods Angiography and chemoembolization via supplying blood arteries of tumor were performed in five patients with pedunculated hepatocellular carcinoma.Interventional procedure was carried out with tumor vascular infusion of 350 mg hot elemene emulsion and tumor embolization by cisplantin-lipidol emulsion(cisplantin 60-80 mg+lipidol 8-15 ml)and glutin.Results Ten interventional procedures(TACE)were undertaken in 5 patients.Angiography showed that tumor blood supply mainly coming from collateral circulation adjacent to the tumors,but partially from hepatic artery.Tumor sizes decreased from 30% to 50% in 5 cases,and AFP declined in 4 cases after the treatment. Conclusion Pedunculated hepatocellular carcinoma possessing different blood supply features from intrahepatocellular carcinomas.But transarterial ehemoembolization is still an effective method of choice for this treatment.

Objective:To compare the differences in dosimetric parameters of target areas between 125I seed implantation with degradable catheters and by hand under the assistance of a real-time intraoperative treatment planning system (TPS). Methods:Forty-two simulated lesions were divided into a degradable catheter group and a free-hand group, with twenty-one lesions in each group. 125I seeds were implanted according to the TPS.The pre-plan and post-implant dosimetric parameters were collected, including the minimum dose ( Dmin), maximum dose ( Dmax), mean dose ( Dmean), conformal index (CI), external index (EI), homogeneity index (HI), minimum prescription dose delivered to 90% of the target volume ( D90), and the mean percentage of volume receiving 90% of the prescription doses ( V90). The Bland-Altman method was employed to analyze the consistency of pre-plan and post-implant dosimetric parameters and the Wilcoxon rank-sum test was used for the comparison of the two groups. Results:According to the Bland-Altman analysis, the dosimetric parameters of the two groups were all in agreement before and after seed implantation except for the Dmin and V90 of the free-hand group.Furthermore, the degradable catheter group had smaller error ranges of Dmax ( Z=-3.824, P<0.005), CI ( Z=-1.962, P<0.005), HI ( Z=-2.352, P<0.005), D90 ( Z=-2.453, P<0.005), and V90 ( Z=-3.159, P<0.005). Conclusions:The dosimetric parameters of 125I seed implantation with degradable catheters under the assistance of real-time TPS have good pre-plan and post-implant consistency and smaller error ranges.
