Objective To study the mental status and its influencing factors of patients with rheumatic disease. Methods Three hundreds and eighty-one patients with rheumatic diseases were assessed with the self-rating anxiety scale, self-rating depressive scale, Eysenck Personality Questionnaire symptom checklist-90, and demographic characteristics questionnaire. The comparison among groups were tested by t tests, Spearman's correlation analysis. Results Patients with anxiety symptoms accounted for 35.96%, and pre-valence rate of depression was 48.03%. The gender (r=0.87, OR=2.34) and duration (r=0.006, OR=1.006) were the risk factors and the C4 (r=-2.63, OR=0.07) was the protective factor. In patients with systemic lupus erythematosus, depression was related to education (Z=2.228, P=0.026), disease duration (Z=-2.015,P=0.044), IgG level (t=-2.266, P=0.027), T cell subsets CD8 (Z=1.981, P=0.047) and CD3 (Z=1.967, P=0.049). Anxiety was related to education (Z=2.452, P=0.014), duration (Z=-2.054, P=0.04), complement C3 (t=2.035, P=0.045), C4 (Z=-2.204, P=0.028) and IgG level (t=-2.126, P=0.036). The value of CRP(Z=-1.984, P=0.047) and IgM (t=2.243, P=0.028) of rheumatoid arthritis patients were higher in the depression group. The depression group was different in disease duration (Z=-2.631, P=0.009), gender ( χ2=4.415, P=0.042), ESR (Z=2.17, P=0.023) and CD3 cell (Z=2.023, P=0.043) in Sj?gren's syndrome patients. Correlation analysis showed positive correlation between the score of SDS, SAS and the P value (r=0.21, P=0.01) (r=0.14, P=0.007) N dimension (r=0.52, P=0.01) (r=0.55, P=0.007) of EPQ. There were negative correlation between the score of SDS, SAS and the E dimension (r=-0.23, P=0.01) (r=-0.14, P=0.006) of EPQ. Conclusion The prevalence of depres-sion and anxiety is higher in patients with depressive and anxious symptoms. They are in older age, female gender, poor education, longer duration, lower complement and lower T cell subsets when compared with those patients without depression and anxiety. Patients who have an introverted, instable, nervous temperament are more likely to be depressed and anxious. Psychological assessment intervention and therapy should be carried out as early as possible.

ve To study the growth curve of Alexandrium tamarense and the toxicity of paralytic shelfish poisoning(PSP) selected in different growth phases, as well as to quantitatively analyze the toxins and compare the different efficiency of breaking cell wall and their virtues and defects between freezing-thawing method and supersonic method, and to provide theoretical basis for the selection of the methods for extraction of PSP. Methods Cells were collected by suction filter, cell wall was broken by freezing-thawing method and supersonic method, the toxicities of Alexandrium tamarense among different growth phases were detected and compared. Results The growth of Alexandrium tamarense typically showed three phases which included a lag phase(0~9 days), an exponential growth phase(10~18 days), and a stationary phase(19~22 days) . The maximum toxicity of cells in the stationary phase appeared, especially in day 21 when the population of cells reached to 9.43?10-6 MU/cell, although the cells in the exponential phase grew fastest. Toxicity of the cells in the lag phase broken by freezing-thawing method was more stronger than that by supersonic method, that meant the toxicity of cells was lowered after the supersonic treatment. In additional, the filtering method for collecting cells presented a lower recovery rate of average 69.0% . Conclusion As for the comparing of freezing-thawing method and supersonic method, it was found that, when cells were in the same phase, the supersonic method had remarkable advantages, but it also had the disadvantage of lowering the tox-icity of cells. When in the same condition of growth and method of fragmentation, cells in the lag phase were broken most easily, and cells in the stationary phase were more difficult to be broken than those in the other two phases. Toxicity of cells was larger and larger with the time of incubation. The toxicity of cells in the lag phase had reached a higher intensity, although toxicities of cells in the next two phases would increase a little.

Objective To understand teachers' cognition and behavior of PBL teaching in nursing college.Methods Eighty teachers were investigated by questionnaire at eight nursing colleges in Hunan province.The percentage was used to do statistical description.Results Totally 75 copies of valid questionnaires were returned,the effective recovery rate was 93.75％.Among all,96％ of teachers thought that teacher was the guide;85.3％ teachers thought that students were knowledge's seekers;93.3％ teachers heard of PBL teaching;81.3％ teaches thought that PBL teaching played a positive role ;74.7％ teaches understood PBL teaching by communication or reading literature; 72％ teachers were willing to try PBL teaching;46.8％ teachers emphasized on multidisciplinary knowledge fusion in teaching; 88.3％ teachers encouraged student discussion in class.The main factors effecting PBL teaching were case and problem design,teaching result evaluation,lack of expert guidance and teacher instruction.Conclusion Teachers have certain understanding of PBL.Organizers should formulate related policies for teachers and students in order to create good education environment.

To explore the associations between the presence of bacteria and virus in the nasopharyngeal secretions, and wheezing, condition and hospitalization period in infants with community acquired pneumonia. Methods Clinical data, inclu-ding detection of bacteria and viruses, conditions and hospitalization period, of 1106 hospitalized infants with community ac-quired pneumonia from March 2009 to February 2010 were retrospectively analyzed. The infants were classiifed into wheezing (697 cases) and non-wheezing (409 cases) groups. Results Viruses were detected in 540 infants (48.8%), and the total detection rate of viruses and detection rate of respiratory syncytial virus in wheezing group were signiifcantly higher than those of non-wheezing group (P=0.000). Bacteria were detected in 590 cases (53.3%) and no signiifcance was found between two groups (P=0.821). The detection rate of Streptococcus pneumonia was higher in wheezing group than that of non-wheezing group (P=0.038). Comparing to the infants detected with both viruses and bacteria, no signiifcances were found in the occurrence of severe pneumonia and hos-pitalization period in those infants detected with viruses only (P>0.05), as well as in the wheezing time of period (P>0.05). Con-clusions Wheezing in infants with community acquired pneumonia is related to the infection of viruses, especially to respiratory syncytial viruses. Virus infection accompanying bacterial infection has no impact on duration of hospitalization and wheezing. The infection of Streptococcus pneumonia may relate to wheezing in infants.

Objective To investigate the effects of motilin on the voltage dependent potassium channel and L-type calcium channel currents in rat proximal colon smooth muscle cells (PCSM) and to explore its mechanism in increasing colonic motility.Methods PCSM were isolated by collagenase.The voltage dependent potassium channel transit outward current (IKA ) and delayed rectifier current (IKdr) and L-type calcium currents (ICa(L)) were measured by whole cell patch clamp technique.Groups were analyzed by paired t-test.Results There was no significant effect of motilin on IKA and IKdr.L-type calcium channel was dose-dependently activated by motilin from 0.5 × 105 mmol/L to 10.0 ×10-5 mmol/L.At 6 × 10-5 mmol/L motilin and under - 10,0 and 10 mV stimulating voltage,maximum current density increased by 154.61％,62.69％ and 21.02％ respectively and activation kinetics curve obviously left shifted.Half activation voltage decreased from (2.740±1.211) mV prior administration to ( - 25.290 ± 0.614) mV (t =8.534,P =0.007 ) and there was no significant difference in slope factor. Conclusions Motilin increases colonic smooth muscle contraction by promoting calcium influx. However the frequency of colonic smooth muscle contraction could not change with frequency of equilibrium potential and action potential of colonic smooth muscle.
