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.

Nosocomial infection is a major challenge in modern hospital management. It affects not only patient safety but also the health of the health care workers. Inappropriate control of nosocomial infections will lead to serious results. China introduced the concept of nosocomial infection control in mid 1980s. Since then, tremendous achievements have been made, while lags still exist when compared with the developed countries. Further efforts should be made to strengthen discipline construction and develop scientific control approaches.

Objective To evaluate the protective effect of curcumin against reperfusion injury of mouse renaltubular epithelial cells in vitro and the related mechanisms. Methods The renal tubular epithelial cells(TECs)were isolated by an improved Percoll density gradient centrifugation method. The cultured TECs were divided into blank group, hypoxia reperfusion group, low-concentration curcumin (5μmol/L) and high? Concentration curcumin (25μmol/L) groups. Apoptoticrate of TECs was examined with FACS, and them RNA and protein levels of TLR4 were detected with RT-PCR and Westernblotting analysis, respectively. Meanwhile, expression of IL-6, IL-1ß, TNF-α and MCP-1 mRNA in TECs was examined by RT-PCR, and their contents in the supernatants of TECs were measured by ELISA. Results The purity of the isolated TECs washigher than 95%, and the cell viability was higher than 93%. Compared with hypoxia reperfusion group, the two curcumin groups exhibited significantly lower apoptotic rates (P<0.01) and lower levels of TLR 4m RNA and protein (P<0.01), inhibited P65 phosphorylation, and significantly decreased levels of IL-6, IL-1ß, TNF-α and MCP-1 in the TECs (at both mRNA and protein levels) and their supernatant (P<0.05orP<0.01). Conclusion Curcumin can protect TECs from reperfusion injury in vitro, which might be associated with the inhibition of TLR4 expression and the consequent attenuation of TLR4- triggered inflammatory damages.

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.
