Objective To investigate the infection statue of new drug experimenters with hepatitis B,as well as liver fuction in 6 kind of infection modes of serum HBV,and to provide evidence for clinical therapy of hepatitis B.Methods 5 immunological HBV markers were measured with ELISA in serum sample of 550 patients before new drug test. Velocity method was applied to detecting serum TBiL,ALT,AST,γ-GT and GLO.Results New drug experimenters with hepatitis B mainly suffered from "small three positive" [HBsAg (+),anti-HBe (+) and anti-HBc (+)] (52.9%),followed by "big three positive" [HBsAg (+),HBeAg (+) and anti-HBc (+)] (28.2%). The rate of hepatic function abnormality was significantly higher in "small three positive" group than that of the other groups (P<0.01),while the rate of hepatic function abnormality was much higher in "big three positive" group than that of the other groups except "big three positive" group (P<0.05).Conclusion In 550 cases of new drug experimenters,HBV are all positive,mostly in "small three positive" or "big three positive" mode. The rate of hepatic function abnormality is markedly elevated in 6 kind of infected modes,in which "big three positive" mode is the highest,followed by "1,3" mode and"small three positive" mode.

Objective To evaluate early hemopeffusion in the patients of acute organophosphate poisoning from economic.Methods Forty patients with acute organophosphate poisoning were divided into early hemoperfusion group (20 cases) and control group (20 cases) according to the condition of early hemoperfusion in three hours after the diagnosis.The date of basal clinical conditions,treatment,prognosis and cost in the 2 groups were observed.Results There were no statistical differences in sex,age,the level of initial acetylcholine esterase (ChE) and degree of poisoning between the 2 groups (P ＞ 0.05).The patients of the 2 groups underwent at least 1 time hemoperfusion.The time of beginning hemoperfusion in early hemoperfusion group and control group were (1.6 ±0.9) h and (6.4 ±3.6) h,and there was statistical difference (P ＜0.05).The time of ChE recovery and length of stay in early hemoperfusion group were significantly lower than those in control group [(8.5 ± 2.1) d vs.(10.0 ± 1.8) d,(10.5 ± 4.2) d vs.(12.3 ± 5.4) d],and there were statistical differences (P ＜0.05).In early hemoperfusion group 5 cases needed rehemoperfusion,and 4 cases needed mechanical ventilation,in control group were 8 and 5 cases respectively.There was no death in the duration of hospital stay and during 28 d in early hemoperfusion group,but in control group death in the duration of hospital stay was 1 case and death during 28 d was 1 case.The total hospitalization cost,daily treatment cost,health care cost and drug cost in early hemoperfusion group were significantly lower than those in control group [(17 231.75 ± 5 411.45) yuan vs.(21 394.52 ± 6 049.81)yuan,(1 412.25 ±169.33) yuan vs.(1 579.41 ±307.19) yuan,(4 309.22 ±1 490.12)yuan vs.(5 581.71 ± 1 681.00) yuan,(8 223.41 ± 1 426.10) yuan vs.(9 790.02 ± 1 909.24) yuan],and there were statistical differences (P ＜ 0.05).Conclusion The patients of acute organophosphate poisoning could be benefit from early hemoperfusion,because early hemoperfusion can shorten the recovery time of ChE,the length of stay,and reduce the hospitalization cost.

Objective To explore the effect of early airway evaluation in critical patients in emergency room.Methods One hundred and sixty-six critically ill patients with routine intubation,according to the condition of early airway evaluation,were divided into early-estimate group (86 cases) and control group (80 cases).The patients in control group due to illness change needed to build artificial airway,tracheal intubation for the first time was done by the doctor on duty,and before intubation grading evaluation of airway was made.The patients in early-estimate group in emergency room had been early estimated using improved Mallampati classification and Thyromental distance by the doctor on duty.The number of cases with first successful endotracheal intubation,endotracheal intubation time,cases with forecast of difficult airway,the number of cases forecast of difficult airway intubation with first time successful endotracheal intubation,the number of cases failed in intubation and needed emergency tracheotomy,and the time of relatively stable vital signs,emergency department mortality were recorded in two groups.Results The endotracheal intubation time,forecast of difficult airway,rate of failing in intubation and needing emergency tracheostomy tube had no statistical significance (P ＞ 0.05).The first time success rate of tracheal intubation and forecast of difficult airway intubation in early-estimate group were higher than those in control group [69.4％ (59/85)vs.40.0％ (32/80),80.0％ (28/35) vs.32.3％ (10/31)],the time of rehtively stable vital signs was shorter than that in control group[(89.5 ± 23.2) min vs.(110.4 ± 48.2) min],emergency department mortality was lower than that in control group [8.2％(7/85) vs.18.8％(15/80)],and the difference was statistically significant (P ＜ 0.05).Conclusion Early-estimation in the emergency room for the critical patients and preparing for the corresponding work is helpful to improve the success rate of first intubation in the patients with difficult airway,and to restore stability to achieve the safe transfer standard as soon as possible.

Objective To increase the anti-tumor effect of 5-ALA-mediated photodynamic therapy, PDT was performed at 635nm followed by an additional irradiation at 670nm, and the effectiveness was studied. Methods PDT was performed at single irradiation (635nm or 670nm), and symphysial irradiation (635nm+670nm), and its effectiveness was studied using PpIXsolutions, tumor cells (9L and HeLa), andHeLa tumor-bearing mice. Results When a Pp IX solution was irradiated at 635 nm or 670nm, singlet oxygen counts were almost similar. Symphysial irradiation -mediated singlet oxygen generation was higher in 9L cells than HeLa cells and it did not produce an additional PDT effect in HeLa tumors. Conclusion It was suggested as the low uptake of 5-ALA in HeLa cells, and the symphysial irradiation can't increase the anti-tumor effects in 5-ALA-mediated PDT. Further study is necessary to obtain the irradiation method for the efficient application of PDT.

Smoking is one of the major risk factors for stroke. Both active and passive smoking may increase the risks of stroke, and the risks of stroke may decrease after smoking cessation, even no significant difference with non-smokers. Because of the different age, sex, smoking quantity, years of smoking, and regions of the smoking popuation, their strokes and the risks of all stroke subtypes are also different.

Transcranial direct current stimulation is one of the non-invasive brain-stimulation techniques. Based on the introduction of the origin and development, this article gave an overview of the mechanisms emphatically, the current view is that the transcranial direct current stimulation may exert effect on neuromodulation by changing cortical excitability, increasing synaptic plasticity, impacting cortical excitation/ inhibition balance, altering regional cerebral blood flow, modulating the activity within and between different cortical networks. In this review, clinical studies and analysis findings were compared, and then 2 problems should be discussed for ideal effects: choice of stimulating parameters and timing of the stimulation in relation to task performance.

Objective To investigate the effects of midazolam on extracellular signal-regulated kinase 1 (ERK1),ERK2 and cyclic AMP response element binding protein (CREB) phosphorylation in hippocampal in rats.Methods Eighty male SD rats weighing 250-300 g were randomly divided into 2 groups ( n = 40) : group control (group C) and group midazolam (group M).The animals underwent a continuous multi-trial inhibitory avoidance training .The times of trial needed for each animal to attain the learning criterion ( 100 s) were recorded.Each animal was given intraperitoneal midazolam 3 mg/kg or normal saline 2 ml/kg at 15 min before training.The memory retention was tested at 0.5,1,2 and 24 h (n = 8,at each time point)after the training session and the memory latency was recorded.The animals were sacrificed 15 min after administration (T0) and after the memory testing (T1-4) and hippocampns was obtained for determination of phosphorylated ERK1 (p-ERK1),p-ERK2 and p-CREB expression.Results Compared with group C,the times of trial to attain the learning criterion were significantly increased,memory latency shortened at T2-4,ERK1 phosphorylation decreased at T0,3.4 while ERK2 and CREB phosphorylation decreased at T0-4.Conclusion Midazolam can inhibit ERK1,ERK2 and CREB phosphorylation in hippocampal in rats.

Objective To investigate the effect of losartan,an angiotensin 1I type 1 receptor antagonist(ATlRA),on transforming growth factor-β1 expression in alcoholic nephropathy in rats.Methods Male adult Wistar rats were random divided into three subgroups and treated daily for 12 weeks as follows,rats were treated with normal saline[20ml/(kg·d)gavage twicely]in vehicle group,rats were treatedwith alcohol[400g/L,8g/(kg·d)gavage twieely]in alcoholic nephropathy,and rats were concomitantly treated with alcohol and Iosartan [200mg/L,ling/(kg·d),gavage]in alcohol+losartan.HE staining,Sirius red staining,electronic microscope,and immunohistochemistry were used to examine histologic changes,collagen fibers deposition,and the expression of TGF-BI.Results Compared with vehicle treated rats,alcoholic nephropathy rats showed tubular vacuolation,granular degeneration,swelling,tubulointerstitial inflammatory cell infil tration,and rarely mesangial proliferation and matrix deposition.Sirius red staining displayed a significant increase in collagen fibers in alias of glomemli,tubulointerstitium and vessels.Concomitant administration of losartan reversed all of above parameters(P<0.05).The upregulated expression of TGF-β1 proteins was significantly suppressed by losartan treatment(P<0.05).Conclusions These findings suggest that alcoholic nephropathy is characterized by the tubular granular degeneration,vacuolation,swelling,and tubulointemtitial inflammato-ry cell infiltration,and this is associated with upregulation of TGF-β1.Losartan treatment offers protection effect by downregulating TGF-β1 expression.
