Objective To accesse the psychological situation of Gastroscopiers. Methods Questional investigation face to face had been done to some gastroscopiers by using SCL-90 chart and the results were comapred to the common model. Results There were no obviously diaappiontment between the results of the gastroscopiers’and the common model. In total fraction , total average fraction and all kinds of elements which proved the normal psychological health of these people. That was to say that it’s not the gastroscopyical check who has caused the supper stimulaion or substaintial passive emotion although more bitterness. Conclutions The psychological situation of Gastroscopiers is basical normal.

Objective:In order to discuss the influence of processed methods to the contents of total saponins and asperosaponin Ⅵ in Dipsacus asperoids,the content alternation of total saponins and asperosaponin Ⅵ in crude and processed Dipsacus asperoids was investigated.Methods:The content of total saponins was determined by spectrophotometry using vanillin-acetic acid-perchloric acid as the chromogenic reagent.The content of asperosaponin Ⅵ in crude and processed Dipsacus asperoids was determined by HPLC.Results: Contracted to the crude Dipsacus asperoids,the content of total saponins in the processed is higher.The content of asperosaponin Ⅵ in the processed Dipsacus asperoids is higher than that in the crude significantly.Conclusion:Different processed mothods affected the content alternation of asperosaponin Ⅵ in Dipsacus asperoids.The processing of Dipsacus asperoids is reasonable.

Pediatric knowledge was not fully learned by seven-year program medical students of pediatrics major in first five years,so two years of postgraduate was the key period for culturing their pediatric specialty.Students of seven-year program were characterized by strong theoretical knowledge but poor pediatric clinic knowledge,therefore,pediatric clinic teaching should emphasize on basic knowledge and skills,avoid dwelling on specific details at early stage,pay attention to their communicative ability with children and their relatives,combine theory with clinic practice and teach from surface to point.Meanwhile,we aimed at changing them into pediatric doctor through cultivating their clinic skills and scientific research ability.

Objective To analyze experimentally the compressive strength of veneers on mottled teeth after Dul8e Nd:YAG laser irradiation.Methods Sixty motded teeth were extracted,including thirty maxdlary central incisors and thirty maxillary lateral incisors and each were divided equally into two groups randomly(experimental groups and control groups).The former were irradiated by pulse Nd:YAG lafer and then etched by 37%phosphorus acid.The latter only etched by 37%phosphorus acid.All the teeth were restored by composite resin veneers and tested with Instron 4505 electronic testing machine.The average collapse loads of the veneers of incisors were tested. The maximal compressive loads of the samples were obtained,then the experimental results were analyzed.Results The average collapse loads of central incisors of test groups and control groups were(0.342±0.053),(0.289±0.041) kN respectively,with a signiticant difference(t=3.16,P<0.05).The average collapse loads of lateral incisors of test groups and control groups were(0.321±0.041),(0.208 ±0.032)kN respectively.There was a significant difference when they were compared(t=7.66,P<0.05).Conclusions The compressive strength of the veneers incneases significandv when the mottled teeth are irradiated by pulse Nd:YAG laser.This method is worthy of recommending.

Scutellarin (SC),a botanical extract,possesses a variety of suppressing free radical generation,anti-inflammatory,cardioprotection and anti-virus activity.Recently,many studies show that SC has inhibitory effects on the growth of many tumors and is a kind of potential anti-tumor drug.Its anti-tumor mechanisms mainly include inducing apoptosis,arresting cell cycle,enhancing the adhesion between cells,inhibiting tumor invasion,reversing multidrug resistance,anti-angiogenesis and so on.

BACKGROUND:Mesenchymal stem cels can differentiate into lung parenchymal cels involved in lung injury repair, providing a new approach for the application of mesenchymal stem cels in patients with chronic obstructive pulmonary disease. OBJECTIVE:To observe the effect of bone marrow mesenchymal stem cel transplantation on the repair of airway injury in rats with chronic obstructive pulmonary disease. METHODS:Twenty-four female rats were randomized into four groups: bone marrow mesenchymal stem cel transplantation group (cel transplantation group,n=12); bone marrow mesenchymal stem cels group (cel control group,n=4); model group (n=4); healthy control group (n=4). Rat models of chronic obstructive pulmonary disease were established in the cel transplantation group and model group using fumigation+lipopolysaccharide method; and at 1 day after modeling, model rats were given 1 mL CM-Dil-labeled bone marrow mesenchymal stem cels and 1 mL PBSvia the tail vein in these two groups, respectively. In addition to tracheal injection of normal saline (300 μL) at 1 and 14 days, rats in the cel control and healthy control groups were given 1 mL CM-Dil-labeled bone marrow mesenchymal stem cels and 1 mL PBSvia the tail vein, respectively. At 1, 7, 15 and 30 days after cel transplantation, lung tissue and serum markers of al rats were detected. RESULTS AND CONCLUSION:(1) Hematoxylin-eosin staining showed that emphysema and airway injury was milder in the cel transplantation group than the model group, but severer than the cel control and healthy control groups. (2) The total number of leukocytes and neutrophils in the peripheral blood was higher in the cel transplantation group than the cel control and healthy control groups (P < 0.05); with time, the total number of leukocytes and neutrophils was decreased gradualy. (3) Compared with the cel control and healthy control groups, the interleukin-10 level in the peripheral blood was lower and the levels of tumor necrosis factor-α and granulocyte colony-stimulating factor were higher at 1 day after cel transplantation (P < 0.05). With time, in the cel transplantation group, the interleukin-10 level was increased gradualy, the level of tumor necrosis factor-α was decreased gradualy, and the level of granulocyte colony-stimulating factor was increased first and then decreased, which was highest at 7 days after cel transplantation. (4) Partial CM-Dil-positive cels were positive for CC16. Taken together, bone marrow mesenchymal stem cel transplantationvia the tail vein can improve lung injury of rats with chronic obstructive pulmonary disease, and it is involved in the repair of airway injury through differentiation into epithelial cels and immune regulation.

Objective: To improve the standardization method for ethanol potassium hydroxide volumetric solution. Methods: A new potentiometric titration method was established and compared with the indicator method described in Chinese Pharmacopeia (2010 edition) . Results:There was no significant difference between the results of the potentiometric method and the indicator method( P>0. 05). Furthermore, the potentiometric titration had significant jump range, good precision and high reliability. Conclusion:The po-tentiometric method can be used in the standardization of ethanol potassium hydroxide volumetric solution.

Objective Working memory (WM) is one of important cognitive functions.The aim of this study was to investigate spatial distributions of electroencephalographs (EEGs) power during visual WM task,which may provide support for studying the principal frequency band and critical region related to WM.Methods 32-channel EEGs were recorded from 16 healthy subjects while they perform visual WM task.The data came from 240 trials and the original EEGs were preprocessed.Fourier transform was applied to calculate spatial distributions of EEGs power in the δ,θ,α,β,γfrequency bands and the percentage of each band in the total power.Results The percentages of δ,θ,α,β,γbands in the total power were (22.44±0.86)％,(31.88±0.55)％,(24.66±1.43)％,(13.54±0.64)％,(7.47±0.48)％,respectively.The power in the θ band was significantly higher than those in the other bands (paired t-test,P＜0.001).The θ power was focused in the frontal midline region.Conclusions The principal frequency band related to WM was the θ band and the critical region was the frontal region.
