Objective To evaluate the intraoperative opioid-sparing effect of different frequency transcutaneous electrical acupoint stimulation (TEAS) in the patients undergoing video-assisted thoracoscopic pneumonectomy.Methods Eighty patients,aged 40-64 yr,weighing 50-90 kg,of ASA physical status Ⅰ-Ⅲ,scheduled for elective thoracoscopic pneumonectomy under general anesthesia,were randomly divided into 4 groups (n =20 each) using a random number table:control group (group Con),stimulation on Lieque (LU7)-Quchi (LI11)-Neiguan (PC6)-Hegu (LI4) at 2/100 Hz group (group 2/100 Hz),stimulation on LU7-LI11-PC6-LI4 at 2 Hz group (group 2 Hz),and stimulation on LU7-LI1 1-PC6-LI4 at 100 Hz group (group 100 Hz).The patients in group Con had the electrodes applied,but received no stimulation.In 2/100 Hz,2 Hz and 100 Hz groups,the patients received 2/100,2 and 100 Hz TEAS on LU7-LI11-PC6-LI4 acupoints ipsilateral to the surgery site,respectively,starting from 30 min before induction of anesthesia until the end of surgery,and the intensity was the maximum current that could be tolerated.Anesthesia was induced with iv midazolam,propofol,sufentanil and cisatracurim,and maintained with target-controlled infusion of remifentanil and propofol,continuous infusion of cisatracurim,and iv boluses of sufentanil when necessary.The target plasma concentration of propofol was adjusted to maintain BIS value at 40-60 during operation.The initial target effect-site concentration of remifentanil was 1 ng/ml,and adjusted to 4 ng/ml at skin incision.The concentration of remifentanil and consumption of sufentanil were adjusted to maintain Analgesia Nociception Index (ANI) at 50-70.When the concentration of remifentanil was increased to 4 ng/ml,ANI was still less than 50,and then 0.1 μg/kg sufentanil was given.The duration of operation and intraoperative consumption of remifentanil and sufentanil (the consumption of sufentanil was converted to the consumption of remifentanil producing the equivalent effect by 1:10) were recorded.Results The intraoperative consumption of remifentanil was significantly reduced in 2/100 Hz group as compared with Con,2 Hz and 100 Hz groups.There was no significant difference in the intraoperative consumption of remifentanil between Con group,2 Hz group and 100 Hz group.Conclusion The use of 2/100 Hz but not 2 and 100 Hz TEAS on LU7-LI11-PC6-LI4 significantly reduces intraoperative opioid consumption in the patients undergoing video-assisted thoracoscopic pneumonectomy.

Orange peel was used as lowcost adsorbent in binding of Methylene Blue.The effects of equilibrium time,pH,dye concentration have been studied.Carboxyl,amine and phosphonate functional groups were present in the orange peel.The equilibrium time was 1 hour,the maximum adsorption capacities of the orange peel was 370.3?31.0 mg/g at pH 10.The Langmuir and Freundlich isotherms were well fitted in this biosorption system.Results showed relatively higher rate constant and biosorption capacities.These adsorption performance indicate the orange peel as a potentially economical adsorbent for dye removal.

Partial nature of "promoting blood circulation and dieresis" of Salvia Miltiorrhizain was initially demonstrated by investigating the regulation effect of AQP2 expression in kidney of trauma blood stasis model rats with the Salvia Miltiorrhizain so as to provide guidance for its clinical deployment of administration. Random allocation was taken to averagely divide 30 SD rats into two groups: 10 rats in normal group and 20 rats in blood stasis syndrome group. Trauma blood stasis rat model was established by quantitatively beating. Then the rat model group was divided into model group and salvia group. After 7 days of treatment, the rat kidney AQP2 expression was detected, the content of urine AQP2 was compared and the damaged local muscle and kidney pathological changes were observed by immunohistochemical method and western blot method. Compared with that of the normal group, rats in model group had inflammatory cells infiltration, blood stasis and edema of the injured local muscles and up-regulated AQP2 expression, decreasing urinary output, and kidney tissues blood stasis and edema (P < 0.05). On the other hand, compared with that of the model group, those parameters of rats in salvia group were all decreasing except urine output (P < 0.05). Such result indicated that Salvia Miltiorrhiza can reduce trauma blood stasis rat content of urine AQP2 and down-regulated AQP2 expression in kidney tissue, so as to reduce the reabsorption of water by renal tubular and increase urine output. The promoting blood circulation effect of Salvia Miltiorrhizain can alleviate the degree of the damaged tissue edema and encourage urine drainage. This therapy is closely related to the effect of regulating AQP2 in kidney by salvia, so the purpose of this study by verifying "promoting blood circulation and diuresis" as the mechanism for the regulation effect of the salvia on AQP2 expression.

Objective To analyze the differential proteomics of ASMC stimulated by wild IL-13 and mutant IL-13 and to investigate the relations of protein profiles of ASMC to asthma and possible targets for the treatment of bronchial asthma.Methods The total proteins of ASMC stimulated by wild IL-13 and mutant IL-13 were separated by immobilized pH gradient(IPG)-based 2-DE and the differentially expressed protein spots were identified by matrix assisted laser desorption-time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE detected approximately(840?21)spots on wild IL-13 samples and(892?17)spots on mutant IL-13 samples(n=3)and(685?19)spots matched.Six significantly differential proteins were subjected to MALDI-TOF-MS analysis and three of them were identified as stathmin 1,Ribosomal protein p~0 and NADH dehydrogenase.Conclusions ASMCs stimulated by wild IL-13 and mutant IL-13 present different proteomic profiles that may shed some light on the mechanism for the asthma causing effect of wild IL-13 and mutant IL-13.

TCM syndrome differentiation system (TCM-SDS) possesses a complex nonlinear characteristic, which determines the falt that the evaluation of TCM efficacy should not be simplified to a causal or linear relationship. Previous selected indexes and methods for evaluating curative effect of Child's pneumonia have their limitations. This paper mainly introduces several thoughts and methods formed in the exploratory researches, employing data mining technology in this field. We believe that efficacy evaluation research of Child's pneumonia on the basis of standardized study of TCM-SDS is a scientific work. Applying data mining method in processing enormous and multilayer information of TCM differentiation has strong advantages in screening evaluating indexes of Child's pneumonia. Meanwhile, some major concerning technical categorizations and implementing strategies for the research are also introduced.
