Objective To analyze risk factors of vascular disease in the lower limbs in type 2 diabetes patients.Meth- ods Investigating the lower limb vein of 80 type 2 diabetes patients with Siemens G-50 color Doppler ultrasonograph, and recording their age,sex,course of disease,and blood pressure,at the same time,take some tests as follows: FBG,P2hBG,FIN,C-peptide HbA_1c,Tch,UAE.Results Compared to the control group,blood pressure, FBG,P2hBG,Tch,TG,HbA_1c,Tch,UAE of the type 2 diabetes patients with lower limb vascular disease,are all increased significantly(P

Recent studies suggest that lacunar infarction is a high risk ischemic cerebrovascular disease highly correlated with the time, which optimistic prognosis is not as good as previously thought.In addition, the role of macrovascular diseases has not been paid attention, it is not conducive to secondary prevention and early intervention for the etiology of lacunar infarction.This review focu-ses on application of imaging diagnosis of lacunar infarction, the etiology of non-lacunar infarct, and differential diagnosis of lacunar in-farction.

Objective To evaluate the clinical value and safety of radiotherapy combined with tyrosine kinase inhibitors (TKI) in non-small cell lung cancer (NSCLC) with brain metastasis driven by epidermal growth factor receptor (EGFR) mutation.Methods A retrospective cohort of 21 non-small cell lung cancer (NSCLC) patients with EGFR mutation-driven brain metastasis was recruited.10 patients (treatment group) were randomly selected for radiotherapy combined with TKI treatment,and 11 patients (control group) were treated with radiotherapy.Tumor size was measured and clinical efficacy was evaluated by MRI in the four weeks after radiotherapy.Since then,a clinical response was evaluated every three months until disease progression,and the median overall survival time was calculated.Results The objective remission was 8 cases in treatment group and 4 cases in control group.The disease control was 9 cases in treatment group and 8 cases in control group.The median overall survival time of treatment and control groups was 11.2 months and 6.4 months,respectively.Adverse reactions in treatment group mainly contained nausea,diarrhea and rash,which all were tolerated.Conclusion Radiotherapy combined with TKI is superior to radiotherapy alone in effect and safety for treatment of NSCLC with EGFR mutation-driven brain metastasis.

A novel solid-phase extraction (SPE) adsorbent for simultaneous extraction of atrazine (ATZ) and its metabolites, deisopropylatrazine (DIA) and deethylatrazine (DEA) from environmental water samples was prepared. Polyacrylonitrile nanofibers (PAN NFs) mat was prepared via electrospinning, and was further functionalized to obtain polypyrrole modified polyacrylonitrile nanofibers (PPy-PAN NFs) mat, hydrazine modified polyacrylonitrile nanofibers (NH2-PAN NFs) mat and carboxyl modified polyacrylonitrile (COOH-PAN NFs) mat. The results showed that the adsorption capacity of COOH-PAN NFs mat was better than other three NFs mats in both static (2.0 mg/g) and dynamic (0.19 mg/g) experiments. Meanwhile, the runoff ratios of COOH-PAN NFs mat were the lowest (less than 30.0％) in the adsorption of three analytes, especially for high polar analytes, which showed that the hydrogen bond between carboxyl groups and analytes was the main interactive force. A combination of mat-based SPE and high performance liquid chromatography-diode array detection was further established for determination of 3 analytes in environmental water samples. The recoveries were 81.4％-120.3％ and the limits of detection were 0.12 ng/mL for DIA, 0.09 ng/mL for DEA and ATZ, respectively.

The effect of bee pollen of Brassica campestris L. and its alcohol extract on lipid peroxidation was observed in vivo and in vitro.The results showed that the production of lipid peroxides in normal liver hotnogenate of mice and elevation of production of lipid peroxides induced by cysteine and FeSO4 in homogenate were found to be inhibited significantly by in vitro addition of alcohol extract of bee pollen.The elevation of lipid peroxides in serum and liver in adult mice induced by alloxan 75 mg/kg(iv)or by administration of peroxidized corn oil 0.2 ml/mouse was markedly inhibited by oral administration of bee pollen (10 g? kg-1?d-1)for 20 days as compared with respective control groups.The level of lipid peroxide in geriatric mice was also markedly lowered by oral administration of bee pollen (10 g?kg-1?d-1)for 3 months as compared to non-treated geriatric mice.Based on the above in vitro and in vivo experimental results, it may be suggested that bee pollen and its alcohol extract protect tissues against destruction by lipid peroxides.

Objective To investigate the mechanism of high-glucose-induced injury to human peritoneal mesothelial cells(HPMC). Methods (1)The cultured HPMCs were exposed to culture medium containing different concentrations of glucose(1. 5% , 2. 5% , 4. 25% )for 48 hours and 4. 25% mannitol and normal culture medium were as control. Then apoptosis was observed by flow cytometry and caspase-3 activity was measured by ApoAlert?CPP33/Caspase-3 Assay kits. (2) The cultured HPMCs were exposed to 4.25% glucose culture medium containing different concentrations of caspases inhibitor, Z-VAD. fmk (25, 50, 100 ?mol/L) for 48 hours and 4. 25% glucose culture medium containing DMSO was as control. Then apoptosis was observed by flow cytometry and caspase-3 activity was measured by ApoAlert?CPP33/ Caspase-3 Assay kits as well. Results (1) Glucose increased caspase-3 activity in a concentration-dependent manner. Compared to control, caspase-3 activity was significantly higher in 4. 25% glucose group and 2. 5% glucose group, but not significantly different in 1. 5% glucose group and 4. 25% mannitol group. (2) Apoptotic rate of HPMC was significantly lower in Z-VAD. fmk group than that in control. Z-VAD. fmk decreased the number of apoptotic cells in a concentration-dependent manner. Also, caspase-3 activity of HPMC was significantly lower in Z-VAD. fmk group than that in control. Conclutions (1) High-glucose can induce apoptosis and caspase-3 activation of HPMC in a dose-dependent manner. (2) Z-VAD. fmk inhibits high glucose-induced apoptosis of HPMC in a dose-dependent manner. (3)High glucose induces apoptosis of human peritoneal mesothelial cells by caspase-3 activation.

Objective To realize the feature of drug resistance in elderly inpatients with tuberculosis in Tianjin. Methods The data of anti-tuberculosis drug sensitivity test of 296 elderly inpatients in Tianjin Haihe Hospital were collected from January 2008 to September 2009. And they were retrospectively analyzed compared with the non-elderly tuberculosis inpatients in the same period.Results (1)The 296 elderly patients with pulmonary tuberculosis were enrolled in this study. The total rate of drug resistance was 28.7% and total rate of multi-drug resistance was 8.8 %. The initial drug resistance rate was 22.2% and initial multi-drug resistance rate was 6.1%. The acquired drug resistance rate was 41.8% and acquired multi-drug resistance rate was 14.3%. (2)The order of drug resistance rate from high to low was isoniazid, streptomycin, rifampin and ethambutal, respectively.(3) The drug resistance rate did not show significant difference among different sex groups (x2 =0. 002, P＞0. 05). (4)The drug resistance rate and multi-drug resistance rate between elderly patients and non-elderly patients had significant differences (x2 = 10.8, 5.24, both P＜0.05). Conclusions The proportion of elderly patients with pulmonary tuberculosis is high, however, its drug resistance rate and multi-drug resistance rate are much lower than non-elderlies.
