Objective:to study psychosomatic factors in patients with psoriasis Method:40 inpatients with psoriasis and 38 normal control were collected Both of them received a battery of psychological tests Result:patients had higher scores in life events, type A behavior, negative coping, anxiety and depression than normal control They had also lower scores in positive coping, social support The risk factors for psoriasis included positive family history, type A behavior, and depression, while protective factors included positive coping and better social support Conclusion:psychosomatic factors have great influence on psoriasis

Objective: To investigate the relationship between psychosocial stress and some neuroendocrine-immuno indexes in patients with psoriasis Methods: The psychosocial factors were evaluated by TABPQ, SDS, SAS, TAS in 40 patients with psoriasis and 38 norm controls The levels of NPY\IL-6\IL-8\Cortisol of both of them were also measured Results: 1 The scores of TH and CH of TABPQ , the scores of TAS and depression and anxiety were higher than the controls(P

Objective To explore whether Forkhead O transcription factor-3a (FoxO3a) activity affects the capability of sphere-formation of ovarian cancer SKOV3 cell line.Methods Sphere-forming cells (SFCs) were obtained and amplified through suspended culture with conditioned medium of the stem cells in SKOV3 cell line.After SKOV3 cells were transfected with FoxO3a specific siRNA,the protein expressions of FoxO3a and Bmi1 and the ratio of sphere-formation were compared with Western blot and sphere-forming assay,respectively.Results Compared to parental cells,SFCs from SKOV3 cell line had higher ratio of sphere-formation and over-expressed Bmi1 and pFoxO3a.Transfection of FoxO3a specific siRNA down-regulated the protein expression of FoxO3a and upregulated expression of Bmi1 in SKOV3 cells,and enhanced the capability of sphere-formation.Conclusions Silence of FoxO3a leads to enhanced capability of sphere-formation in SKOV3 cell line.

To improve the quality of experimental teaching,investigating the independent design experiments are carrying out in preventive medicine by public health experimental teaching center in our school.We take preventive medicine professional as an example,and besides the classical basis experiments,some experiments are verification project at present,in which students are not strongly interested.On the basis of the integration of the classic experiments,according to the national standard of the experimental method,we are trying to carry out part of the independent design experiments to meet the needs of students learning.The effect of those independent design experiments shows that it is appropriate carrying out independent design experiments on the basis of the existing classical experimental project in preventive medicine experimental teaching,to a certain extent,which will stimulate students' learning interest and enhance their sense of achievement.This study is conducive to the cultivation of medical students' innovation,independent thinking,analysis and problem-solving ability,practical ability and teamwork spirit.

Background and purpose:Ovarian cancer is associated with a high recurrence and mortality due to the existence of cancer stem cells. The purpose of this study was to investigate the effect of casticin (CAS) on the capability of self-renewal in ovarian cancer stem cell like cells (OCSLCs) derived from SKOV3 cell line. Methods:SKOV3 cell line cells were cultured in vitro, and OCSLCs were obtained and amplified through suspended culture with conditioned medium of the stem cells. The phosphorylation level of FoxO3a was analyzed using Western blot. The protein expression of FoxO3a was inhibited by FoxO3a speciifc siRNA transfection, and then the ratio of sphere-formation was detected. Results: Compared with parental cells, OCSLCs over-expressed phosphorylated FoxO3a (pFoxO3a) and had elevated ratio of sphere-formation [(3.1±0.3)% vs (34.8±6.8)%, P<0.05]. CAS significantly inhibited the capability of sphere-formation in OCSLCs and down-regulated the expression level of pFoxO3a. And the transfection of FoxO3a speciifc siRNA suppressed the protein expression of FoxO3a and attenuated the inhibitory effect of CAS on the sphere-formation of OCSLCs. Conclusion: Reduced expression level of pFoxO3a is involved in the effect that CAS inhibits sphere-formation of OCSLCs derived from SKOV3 cell line.

Objective To explore the effects of Huperzine A on memory in rats with repeated electroconvulsive stimulation. Methods 48 adult male Sprague-Dawley rats were randomly divided into true electroconvulsive stimulation group (E group) and sham electroconvulsive stimulation group (C group). Then both groups were randomized to receive Huperzine A (EH group and CH group) or normal saline (ES group and CS group). There were 12 rats in each subgroup. Huperzine A or normal saline was administered during 1~17 d. During 8~17 d,true or sham electroconvulsive stimulation were administered. On the 18th d, the rats were tested in Morris water maze. Then 6 rats of each group were randomized to be taken for probe tests after 48 h. Memory test indexes include swimming speed, latency, and search time. Results There was no significant difference in the latency between CS group and CH group (P>0.05). The latency was significantly longer in ES group than in CS group (P<0.01), and shorter in EH group than in ES group (P<0.05). There were significant difference in the search time between around the hidden platform and in the opposite area in CS group, CH group and EH group (P<0.05). But there was no difference in ES group (P>0.05). Conclusion Chronic repetitive electroconvulsive stimulation can lead to spatial memory impairment in rats. Huperzine A may attenuate electroconvulsive stimulation induced amnesia.

Objective To analyze the clinical features,epidemiologic information and outcome in confirmed cases of human infection with a highly pathogenic influenza A(H5N1).Methods The clinical features and epidemiologic findings in 2 confirmed cases of avian influenza A(H5N1)in Anhui province,in November 2005.Clinical data on vital signs,physical findings,laboratory tests and roentgenology were obtained by means of retrospective review of the hospital records.Epidemiologic data were collected through interviews of the patients and their relatives.Results In both cases,the diagnosis of influenza A(H5N1)was confirmed by means of viral culture and real-time polymerase chain reaction with specific primers for H5 and N1 in samples obtained from tracheal aspiration.All patients were previously healthy young women and resided in village.They had a clear history of di- rect contact with sick/dead poultry and prepared dead chickens at home for eating(removed feathers, washed,cut)hut no report of confirmed HSN1 animals in the village.The time between exposure and onset of illness were 5 days,no one else in family sick.The time between the onset of illness and hos- pitalization were 5 days and 6 days,respectively.Two patients have initial symptoms of high fever (typically a temperature more than 38℃).The prominent clinical features were those of influenza syndrome,including fever,cough,and shortness of breath.Upper respiratory tract symptoms were absent.The platelet counts were decreased.In both patients,there were marked abnormalities on chest radiography,radiographic changes include bilateral and unilateral lobular consolidations with air bronchograms,and had dramatic worsening of findings.Two patients developed acute respiratory dis- tress syndrome(ARDS)complicated multiple organ dysfunction syndrome(MODS)and died of pro- gressive respiratory failure.Conclusions Exposure to dead poultry within a week before the onset of illness was associated with Influenza A(H5N1)infection in humans,but no definitive evidence of hu man-to-human transmission has been found yet.Influenza A(HSNI)infection,characterized by fe- ver,an influenza-like illness with lower respiratory tract symptoms,carries a high risk of death.

Citrus aurantium is one of the most common traditional Chinese medicines. In this paper, the chemical components, content determination and pharmacological actions of C. aurantium were summarized for the comprehensive utilization of its resources. Because of the complicated resources of C. aurantium, only one single component as index couldn't reflect the quality and effects and comprehensive evaluation which concluding multiple components should be established in the future quality control. In recent years, the pharmacological effects research of C. aurantium has made tremendous progress, and it is important to explore new drugs from the development and utilization of the active ingredient of C. aurantium.
