Objective To discuss effects of Wugong Baidu Drink on expressions of Bcl-2, NF-κB mRNA genes related to the apoptosis of HaCaT in psoriasis. Methods Wistar rats were randomly divided into 6 groups:blank group, Western medicine control group, TCM control group, and Wugong Baidu Drink high, medium, and low dose groups. They were given normal saline, methotrexate suspension, compound natural indigo capsule suspension, and the different doses of Wugong Baidu Drink for gavage, respectively. Drug-containing serum of each group was prepared, and was put in the HaCaT respectively to subculture. The intervention effect of different Drug-containing serums on expressions of objective genes were detected through PR-PCR method. Results Drug-containing serum of each group could decrease the expressions of Bcl-2 mRNA and NF-κB mRNA. The most obvious effects were shown in the groups of Western medicine control group and Wugong Baidu Drink high dose group. All Wugong Baidu Drink groups showed a dose-response relationship. Conclusion Wugong Baidu Drink probably can promote the apoptosis of HaCaT by reducing the gene expressions of Bcl-2 and NF-κB. It can also decrease immune response by regulating serum factors related to T cells to play the role of anti-psoriasis.

Objective To investigate the NOx(nitrogen oxides,esp.NO2) output of household ozone generator and the control method.Methods Ion chromatogram,pH detection and iodine titration were used to study the outputs of ozone and the by-product,NOx,generated by some certain household ozone generator in normal operation condition.The method of controlling NO2 simply by pure water absorption was also studied.Results At about 15 min,the ozone generator produced NO2 and turned into NO3-,the amount increased along with the operating time.After 60 min,the NO3-was almost in proportion to the operating time,the pH value decreased clearly.pH value was a proper and simple substitute parameter to display the generation and accumulation of NO2.NO2 could be efficiently controlled by pure water absorption.NO3-absorbed in a 0.1 mol/L NaOH solution was less than 0.01 mg/L after a pure water absorber which had an effective depth of 12cm,with little influence of ozone production.Conclusion NO2 will be generated inevitably and the amount of the by-product increases with the running time of the household ozone generator.Pure water absorption is efficient to control NO2 generation.

Mental task classification is one of the most important problems in Brain-computer interface. This paper studies the classification of five-class mental tasks. The nonlinear parameter of mean period obtained from frequency domain information was used as features for classification implemented by using the method of SVM (support vector machines). The averaged classification accuracy of 85.6% over 7 subjects was achieved for 2-second EEG segments. And the results for EEG segments of 0.5s and 5.0s compared favorably to those of Garrett's. The results indicate that the parameter of mean period represents mental tasks well for classification. Furthermore, the method of mean period is less computationally demanding, which indicates its potential use for online BCI systems.

Objective To investigate the clinical features of early postoperative inflammtory small bowel obstruction,and discuss its diagnosis,treatment and preventive measures.Methods The clinical data of 68 cases of early postoperative inflammatory small bowel obstruction were analyzed retrospectively.Results Within the 68 cases,65 cases were cured by non-operative treatment including gastrointestinal decompression,anti-inflammatory drugs,somatostatin,total parenteral nutrition(TPN) and traditional Chinese medicine.The mean time from the onset of symptoms to the recovery of bowel function was 14 days.Three cases were cured by transferring to operation.One case of them was transferred to operation for strangulated intestinal obstruction during the period of conservative treatment.One case underwent oper.ion because the patient didn t recover after 4 weeks expectant treatment.One case underwent operation for the impatience with the conservative treatment of both the doctors and the patient.Conclusion Non-operative therapy should be the first choice for the treatment of early postoperative inflammatory small bowel obstruction,and its therapeutical effect was well-accepted.
