ABSTRACT
Objective To study the status of professional commitment and its effect on self-esteem of non-medical undergraduates in medical colleges. Methods Totally 410 non-medical under-graduates and 403 medical undergraduate were investigated by professional commitment of undergrad-uate scales and self-esteem questionnaire of undergraduates. T test,chi-square test,ANOVA,corre-lation analysis and multiple regression analysis were employed to do statical analysis,with P<0.05 be-ing statistical differences. Results Non-medical undergraduates’scores of professional commitment (85.11 ±11.60)and self-esteem (2.57 ±0.37)were lower than those (93.82 ±11.43)and (2.62 ± 0.35) of medical undergraduates. There were statistical differences in non-medical undergraduates’ professional commitment concerning the variables of professional consistency (t=5.657,P=0.000)and grades (F=8.528,P=0.000). Professional commitment of non-medical undergraduates was positively correlated with self-esteem. There was linear regression relationship between the variables of emotion-al commitment (P=0.005),normative commitment (P=0.006)and self-esteem. Conclusions Non-medical undergraduates' professional commitment and self-esteem levels are lower than those of medical undergraduates. The professional commitment could produce obvious effects on self-esteem.
ABSTRACT
Objective To investigate the changes of plasma thrombomodulin (TM),tissue factor (TF),tissue factor pathway inhibitor (TFPI),P-selectin (P sel),von Willebrand factor (vWF) and D-dimer (D-D) levels in patients with hemorrhagic fever with renal syndrome (HFRS) and its clinical significance.Methods Twenty-three cases of HFRS were divided into two groups according to the severity of disease (12 cases in mild group and 11 cases in severe group),and 20 healthy individuals served as control group.Blood samples were collected at every stage of the disease.Plasma TM,TF,TFPI,P-sel and vWF were measured by enzyme-linked immunosorbent assay (ELISA); plasma D-D was detected by nanoparticles enhanced turbidimetric immunoassay; creatine kinase MB isoenzyme (CKMB) was tested by immunosuppression assay; blood clotting time was recorded for blood coagulation functions; blood urea nitrogen (BUN),creatinine (Cr),alanine aminotransferase (ALT),aspartate aminotransferase (AST),and platelets (PLT) were also routinely tested.The comparison between groups was done by analysis of variance and two sided t test.Results During the acute phase of HFRS,the plasma levels of TM,TF,P-sel,vWF and D-D were significantly increased,activated partial thromboplastin time (APTT) was prolonged,international normalized ratio (INR) was elevated,while fibrinogen (Fn) and PLT were decreased markedly as compared to control group.In febrile phase,there were significant differences between severe group and mild group in plasma TM [(1.78±1.00) μmol/L vs (1.33±0.35) μmol/L,t=2.600,P＜0.01],TF [(36.63±8.48) ng/L vs (32.93±10.61) ng/L,t=3.423,P＜0.01],vWF [(327.1±57.2) μg/L vs (260.3±63.2) μg/L,t=2.257,P＜0.01],APTT [(63.9±20.5) s vs (48.7±18.6) s,t=4.920,P＜0.01],and INRlevels(1.8±0.6 vs 1.5±0.4,t=2.276 P＜0.05).The variation curves of TM,P sel,APTT,INR and D-D were similar to those of BUN and ALT,but contrary to PLT count.Conclusions There are significantly elevated plasma levels of TM,vWF,P sel and D-D,prolonged APTT,increased INR,and much decreased plasma Fn and PLT in the acute phase of HFRS,suggesting the presence of extensive capillary injuries and activation of platelet and coagulation system,which is closely associated with kidney,liver and cardiac muscle damage.Hence,it is essential to use antiviral agents,anticoagulants and fluid resuscitation in the early stage of the disease.
ABSTRACT
BACKGROUND: The rehabilitative intervention accelerates the recombination and reconstruction of cerebral structure and function and then promotes the amelioration of function.OBJECTIVE: To evaluate the influence of early and late rehabilitative interventions on the motor function and activities of daily living (ADL) with neurologic deficit score (NDS), Fugl-Meyer assessment (FMA) and modified Barthel index in patients with cerebral infarction.DESIGN: A randomized controlled trial.SETTING: Department of Neurology, Qilu Hospital of Shandong University; Department of Rehabilitation, Jinan Great Wall Hospital; Department of Neurology, the Third People' s Hospital of Heze.PARTICIPANTS: Totally 216 inpatients with cerebral infarction (125 males and 91 females, aged 60-75 years), who were selected from Qilu Hospital of Shandong University, Jinan Great Wall Hospital and the Third People's Hospital of Heze from December 2000 to December 2003, were randomly divided into early rehabilitation group (n=108) and late rehabilitation group (n=108) after admission.INTERVENTIONS: In the early rehabilitation group, the patients began to receive rehabilitation at 48 hours to 14 days after the stability of vital signs and absence of the progress of neurological signs. In the late rehabilitation group, the patients began to receive rehabilitation at 15-30 days after attack. They were trained with Bobath method and motor relearning program, once a day, 45 minutes for each time, and 6 times every week.Before and 30 days after the rehabilitative treatment, the rehabilitation was evaluated with modified Barthel index (100 points as normal, 0-20 as extremely severe functional defect, 25-45 as severe functional defect, 50 -70 as moderate functional defect, 75-95 as mild functional defect), FMA (total score was 100 points, including the highest scores of upper and lower limb movement were 66 and 34 points respectively) and NDS (the highest and lowest scores were 45 and 0 point, 0-15 as mild, 16-30 as moderate, 31-45as severe).ter treatment.RESULTS: All the 216 patients with cerebral infarction were involved in obviously lower than that before treatment in both groups (P ＜ 0.01), lower in the early rehabilitation group than in the late rehabilitation group score at 30 days after treatment was obviously higher than that before treat ment in both groups (P ＜ 0.01), higher in the early rehabilitation group than in the late rehabilitation group [upper limb: (32.43±21.52), (26.69±19.79)dex: The modified Barthel index at 30 days after treatment was obviously higher than that before treatment in both groups (P ＜ 0.01), higher in the early rehabilitation group than in the late rehabilitation group [(54.23±30.33),(46.57±29.85) points, P ＜ 0.05].CONCLUSION: Both early and late rehabilitative interventions can obviously accelerate the recovery of neurological function, motor function and ADL, but the effect of early rehabilitative intervention is superior to that of the late one.
