Therapeutic hypothermia has been shown to improve neurological outcomes after global ischaemia/hypoxia in patients who have had cardiac arrest. Therapeutic hypothermia is one of the most extensively studied and influential therapeutic strategies of acute ischemic stroke. Previous studies of therapeutic hypothermia mainly focused on whole-body cooling. However, delayed induction and systemic complications have limited the clinical application of whole-body cooling. As a selective cerebral hypothermia, the selective intra-arterial brain hypothermia treatment has the characteristics of rapid and even induction of hypothermia, and less affecting the core body temperature. Therefore, it has become a promising treatment modality. This article reviews the application of selective intra-arterial brain hypothermia in acute ischemic stroke and its advantages and limitations in order to provide reference for further experimental studies and future clinical trials.

OBJECTIVETo analyze the literature on power frequency electric field testing data and to propose views and suggestions for current testing.

METHODSThe literature on power frequency electric field testing data published in the previous years was searched to identify 306 articles involving 193 valid testing data. Mann-Whitney test and Wilcoxon W test were used for analyzing the testing data.

RESULTSThe classification of data was carried out according to one quarter of occupational exposure limit (1.25 kV/m), one half of the exposure limit (2.5 kV/m), and the exposure limit (5 kV/m). The structure of testing data showed a significant difference between the non-power facility group and the power facility group (P<0.05).

CONCLUSIONAs occupational hazard factors, the radiation exposure from power frequency electric field is extensive. However, the power frequency electric field testing data in actual workplaces except high-voltage power facilities are far less than the occupational exposure limit with little harmfulness. There is a phenomenon of excessive testing at present.

Objective To study the signal transduction pathway for myocyte contraction induced by Substance K (SK) in rats. Methods The fluorescent Ca 2+ indicator Fluo 3AM was used to quantitate the calcium signal directly in the primary cultured myocardial cells. Changes of free Ca 2+ concentration in cardiac myocytes were detected by flow cytometry. The phospholipase C (PLC) inhibitor, neomycin and IP3 receptor antagonist, heparin, were used to block signal system of phosphates Ca 2+ in order to investigate whether they took part in the SK induced changes of [Ca 2+ ]i in myocytes. Results SK(1.78?10 -5 mol/L) elevated [Ca 2+ ]i in myocytes. The effects could be blocked by neomycin and heparin. Conclusion SK can elevate [Ca 2+ ]i in myocyte, which may be mediated by a signal system of phosphates Ca 2+ .

Objective To investigate the effect of FK506 on the expression of TNF -? mRNA in isolated liver with reperfusion. Methods After the model of isolated liver with reperfusion was set upp,the expression of TNF-? mRNA was detected with RT-PCR in different preservation time of the isolated liver. Results In FK506-treated group, expression level of TNF-? mRNA was obviously lower(P

Objective To investigate the effect of coenzyme complex on the cardiac and renal functions of patients with type 2 cardiorenal syndrome. Methods Sixty-two patients with type 2 cardiorenal syndrome were enrolled in from June 2013 to December 2014 in Zhujiang Hospital , Southern Medical University. These patients divided were into routine group (n = 31) and coenzyme complex (n = 31). The therapy scheme of coenzyme complex group was on the basis of routine group with coenzyme complex intravenous drip , 400 U/day for 2 weeks. The cardiac function was determined by New York Heart Function Assessment, and the cardiac ultrasound, the levels of BNP. The renal function was determined by serum creatinine and urine volume. Results Compared with routine group, the rates of NYHA Ⅲ and Ⅳ were reduced, the LVEF levels were increased and the levels of BNP were increased (P < 0.05). The serum creatinine was decreased and urine volume were increased in the coenzyme complex group (P<0.05). Conclusion Coenzyme complex could improve the cardiac and renal functions of the patients with type 2 cardiorenal syndrome.

Objective To investigate the expression of vascular endothelial factor C(VEGF-C) and E-cadherin in gastric cancer and explore the relationship between expression of VEGF-C and E-cadherin and the pathogenesis of gastric cancer.Methods Real-time quantitative reverse ranscriptase-polymerase chain rection was applied on 40 cases of gastric cancer and corresponding adjacent noncancerous tissues,in order to detect mRNA expression of VEGF-C and E-cadherin gene.VEGF-C and E-cadherin protein expression in gastric cancer and adjacent normal gastric mucosa were detected by immunohistochemistry.Statistical analysis was carried out to analyze the correlation among VEGF-C,E-cadherin and protein expression with various clinical parameters in these gastric cancer patients.Results The expression of VEGF-C protein in 40 cases of gastric cancer's cancer tissues was 0.461±0.012,significantly higher than that in the adjacent normal tissues(0.036+0.023;t=1.101,P＜0.05),but E-cadherin expression was significantly lower than that of the adjacent normal tissues (0.079±0.002 vs.0.321±0.005;t=1.844,P＜0.05).There was correlation between VEGF-C mRNA expression with histological grading,TNM staging,lymph node and distant metastasis (t=-1.621,-1.474,-2.378,-1.966,P＜0.05).There was correlation between E-cadherin mRNA expression with tumor size,histological grading,TNM stage,there was a significant difference (t=1.875,1.673,1.544,P＜0.05).VEGF-C and E-cadherin protein expression was negatively correlated(r=-0.688,P＜0.05).Conclusion Up-regulated of VEGF-C gene and decreased expression of E-cadherin may play an important role in the carcinogenesis of gastric cancer
