Based on the kinetics of alcohol metabolism in animal models,the mathematicalmode for studing of the alcohol kinetics in person of the acute alcohol poisoningwas established.This mathematical mode can be expressed as x(t)=x_0(1-e~(-kat))-k_bt,which allows calculating the absorpion constant (k_a) arld breakdown rate constant(k_b) for alcohol the curve in dynamic change of the alcohol concentration followingadministration of a large amount of alcohal can be obtained the amount of alcoholin human body [x,(t)] after drinking can be checked out.from the urine Theexperimental study in monkeys showed that the parameters derived from the mathe-matical mode agued witk the results obtained from the experiments

Objective To investigate the role of color Doppler flow imaging(CDFI)in the early diagnosis of heterotopic ossification after spinal cord injury.Methods Serial CDFI and X-ray were performed per week in 39 patients with spinal cord injuries who were suspicioned with heterotopic ossification clinically.Results The finding under the CDFI including:losing of the regular lamellar pattern of the muscle fibres,chaotic irregular echogenic pattern,echo-free heamatoma,calcification,and extrinsic venous compression.There was statistical significance of incidence of diagnosis between CDFI and X-ray within a week(PP<0.01).Conclusion CDFI is effective on the early diagnosis of heterotopic ossification.

Objective: To study the effect of chronic stress on spatial learning and memory and nitric oxide (NO) in hippocampus of the rats Method: Chronic stress model was established by electric-foot accompanied with noise Morris watermaze was used to observe spatial learning and memory abilities, contents of NO and activities of NOS in hippocampus were measured during the test Result: The spatial learning and memory of chronic stress rats were significantly decreased in Morris watermaze Contents of NO (3 87?0 47 nmol/mgpro) and NOS activity (102 64?13 33 pmol/mgpro/min) in hippocampus of the stress rats were significantly higher than that of normal rats (2 76?0 43 nmol/mgpro, 78 25?10 67 pmol/mgpro/min respectively) Conclusion: Chronic stress impairs spatial learning and memory abilities of rats, which may be related to the increase of NO in their hippocampus

Objective:To explore the status of job burnout among clinical nursing teachers in different depart-ments, in order to provide reference for the nursing education management .Methods:The questionnaire of Maslach Burnout Inventory ( MBI) of revised Chinese Version was distributed to 535 clinical nursing teachers .Results:The incidence of job burnout was 48 .3%, while the incidences with mild , moderate and severe job burnout accounted for 18 .9%, 15 .7%, 9 .3%respectively .Clinical nursing teachers in different departments have diffrences on oc-cupation actions .Clinical nursing teachers in the operation room revealed a significant greater personal accomplish -ment, but the emergency department scored lower .The teachers in emergency department scored higher on emotion-al exhaustion than those in other departments , and the teachers in oncology department is the secondary in scores of emotional exhaustion .The scores of the teachers in oncology department were the highest on depersonalization among all the departments,while the teachers in infection department is at the secondary place .Conclusion:The clinical nursing teachers'job burnout should be paid attention to .Strategies including intervention by nursing education management and teachers'learning and training should be taken to reduce the damage of physical and mental health caused by burnout and increase the clinical care and teaching quality .

Objective To investigate the protective effects of melatonin and possible mechanisms on rats with alco-holic fatty liver (AFL). Methods All rats were randomly divided into 4 groups: normal group (n = 10), model group (n = 12) and melatonin groups (10 mg / kg, 20 mg / kg; n = 10, respectively). The model of rats’ alcoholic fatty liver was induced by intragastric influsion of ethanol for 8 weeks. The melatonin groups’ rats received melato-nin by intraperitoneal injection after intragastric infusion of ethanol. Histopathological changes were evaluated by hematoxylin and eosin staining. The expressions of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected by immunohistochemical methods. The detection of aspartate aminotransferase (AST) levels and alanine transarninase (ALT) levels and the total bilirubin ( TBIL) levels in serum were provided by routine laboratory methods using an autoanalyzer. The levels of malondialdehyde ( MDA) and activities of glutathione peroxidase ( GPx) were measured by spectrophotometry. Results Compared with the normal group, the liver cells of the mod-el group showed obvious steatosis and significant swelling. However, less degree and less extensive of steatosis and swelling were observed in the melatonin groups. Compared with the normal group, the levels of ALT, AST and TBIL in serum and the levels of MDA in liver homogenates were significantly increased in the model group (P <0. 01), and the activities of GPx were distinctly decreased in the model group(P < 0. 01). But in the melatonin groups, the levels of ALT, AST and TBIL in serum and the levels of MDA in liver homogenates were decreased (P< 0. 01), and the activities of GPx were increased (P < 0. 01). Additionally, melatonin lessened the expression of TNF-α and IL-6 in liver obviously (P < 0. 01). Conclusion Melatonin may inhibit the development of alcoholic fatty liver and its possible mechanism is the ability to resist oxidative stress and lessen the expression of TNF-α and IL-6 and other relevant factors in liver.

Through discussing the connotation of medical humanities spirit and the current situation of medical humanities education in our country, the authors put forward that in clinical practice, respiratory medicine interns medical ways for the cultivation of the humanistic spirit, which include: guide the trainee doctors in treating pa-tients alike, on the basis of understanding and respect for life and death;to cultivate the ability of effective commu-nication between patient and physician internship; interns cultivated the spirit of collaboration and leadership skills;the in-depth, on the basis of clinical practice, in practice the doctor to write a detailed records;construc-tion of a high level of teacher love team, set an example for the students.

Objective To identify the immunogenicity and the potential of using Schistosoma japonicum mitochondria related protein(rSj338) as a candidate vaccine antigen for Schistosomiasis japonica . Methods The expressed recombinant fusion protein(rSj338/26GST) was purified and recognized by S.japonicum heavily infected rabbit sera and rSj338/26GST immunized rabbit sera by Western blotting. The inclusion bodies,the revivified protein and the purified protein from S 12 gel filtration were injected twice into rabbits to produce anti rSj338/26GST antibody which titer was then measured by dot ELISA. Balb/c mice were immunized with the inclusion bodies and the purified protein from S 12 gel filtration and challenged with S. japonicum cercariae to identify the protective immunity produced by rSj338/26GST. Results The inclusion bodies, the revivified protein and the purified protein from S 12 gel filtration could stimulate the rabbits to produce high level of anti rSj338/26GST antibodies and could be recognized by S. japonicum heavily infected rabbit sera and rSj338/26GST immunized rabbit sera. In Balb/c mice, the inclusion bodies could induce 27.8%( P
