Young medical teachers after 80 s have the characteristics of knowledge update quickly , but accumu-lations are not deep;being good at innovation , but are insufficient in clinical and teaching experiences;the genera-tion gap between teachers and students is narrow and so forth .Based on the characteristics of young medical teach-ers after 80 s, this paper proposed the ways for cultivating their professional ethics:perfect the pre-service teacher's ethics education system , increase the awareness of the young teachers in medical and investment;into the campus culture spirit , multilateral force and improve the mechanism of teacher's ethics construction;to medical teachers as the main body , the development of the life from the necessity to cause teachers'transformation;to medical students as object of love of life , from knowledgeable teachers to life style change .

Objective To analyze CT features of gastrointestinal stromal tumors(GIST) and to evaluate its value in diagnosis of thedisease.Methods Both plain and enhanced CT findings in 32 cases with GIST pathologically-proved were retrospectively analyzed.Gastrointestinal air-barium double contrast radiography was performed in 15 patients . Results The tumors originated from the stomach (n=18),jejunum(n=4),ileum(n=3),esophagus(n=2),mesentery(n=2),ascending colon(n=1),rectum(n=1) and greater omentum(n=1).Of 32 GIST,12 were benign and 20 were malignant.In benign GIST ,the diameter of the tumor was less than 5cm,with clear margin and homogeneous density.In malignant GIST,the diameter of the tumor was more than 7 cm,the tumors were lobular in shape ,with necrosis within the tumor ,the tumor had large and deep ulcers,invasion of adjacent tissues and metastasis.The positive predictive value of CT for location of GTST was 96.9%(31/32),the positive predictive value of CT for differentiation of benign and malignant GIST was 93.8%(30/32).Conclusion CT is of great value in diagnosis of GIST.It can be considered as a supplement to X-ray barium meal examination and can provide useful informations for early diagnosis and for the evaluation of the treatment and prognosis.

Objective To explore the influence of the sequential enteral nutrition(SEN) on nutritional status and prognosis in patients with acute cerebral infarction(ACI).Methods 80 ACI patients complicated with dysphagia were divided into SEN group and control group(40 cases in each group).In the first three days patients in SEN group were treated with nasal feeding short-peptide enteral nutrition[84~126(kJ/kg.d) ],than,which would be replaced with nasal feeding integral-protein enteral nutrition from the forth day.Patients in the control group were provided with ordinary fluid food by nasal feeding.Nutrition support for both groups was at last more than 10 d.In the 1 d,7 d and 14 d after treatment,data of both groups concerned with triceps skin fold(TSF),mean upper arm muscle circumference of triceps(MAMC),serum albumen(Alb),serum prealbum(PAB),heamoglobin(Hb),incidence of infectious complications,National Institutes of Health Stroke Scale(NIHSS) score and Barthel index(BI) were examined.Results Nutritional indexes(TSF,MAMC,Alb,PAB,Hb) in the SEN group were significantly higher than those in the control group(P

Objective To analyze the CT features of intestinal tumor obstruction, and explore its CT value.Methods CT manifestation and clinical materials of intestinal tumor obstruction proved by surgical findings or endoscopy biopsy in 35 cases were analyzed restrospectively, and compared with the results of surgery-pathology and endoscopy. Results CT findings were consistence with the results of surgery-pathology and endoscopy in 33 of 35 cases. The CT diagnostic accuracy of intestinal obstruction was 100%. And the accuracy of the cause was 94%, including colon carcinoma in 25, lyphoma in 5, gastrointestinal stromal tumor in 2, and lipoma in 3.Conclusion CT has unique advantage in examining intestinal tumor obstruction, not only for definiting the existence of the obstruction, but also locating the site of obstruction diagnosing the cause and chosing the appropriate treatment.

Objective:To study the reasons and preventive measure of the effect of human urinary kallikrein on blood pressure in the treatment of acute cerebral infarction.Method:Documents about the effect of human urinary kallikrein on blood pressure of pre-clinical study and the phaseⅠ-Ⅲclinical trials were collected and analyzed in combination with the related information of the phaseⅣclinical trial from our hospital.Result:The rate and concentration of medication in combination with ACEI were the reasons for the effect of human urinary kallikrein on blood pressure.Conclusion:Controlling the rate and concentration of medication and forbidding the combined use of ACEI from the 72hr before the medication and the 24hr after it can prevent hypotension caused by human urinary kallikrein.

Objective To investigate the diagnostic Value of multi-slice spiral CT 3-Dimensional reconstruction in intestinal obstruction.Methods 28 Patients with malignant lesions of colon underwent volume scanning using multislice helical CT.Four types of reconstruction included multiple planner reconstruction(MPR),CT virtual colonoscopy(CTVC),shaded surface display(SSD)and raysum.The results were compared with those of colonoscopy and patholog.Results CT diagnostic accurate rate was 100%,and the accurate rate of the cause was 96% in intestinal obstruction,including primary or secondary neoplasms(18/28),abhesions(2/28),bowel torsion(2/28)and external or internal hernias(3/28) and gallstone ileus(3/28).Conclusion There were advantages and disadvantages in diagnosis of mechanical intestinal obstruction with MPR,CTVC,SSD and Raysum respectively.The combined use of the four post-processing technigues can be more helpful to precise localizing and qualitative diagnosis of lesions.MPR should be the optimal post-processing technigues for the diagnosis of intestinal obstruction

Objective To explore the clinical characters of drug-associated spinal subarachnoiditis. Methods 6 patients with spinal subarachnoiditis were analyzed retrospectively. Results All the patients appeared acute onset, numbness and weakness of lower limbs, incontinence, dramatic increase of protein with normal or mild increase of WBC in cerebral fluid regulation. Conclusion Spinal subarachnoiditis, if occurs, is resistant to variety of medication, and lead to the poor outcome. Prevention is most important.

Objective To investigate the clinical effect of resuscitating acupuncture and scalp acupuncture on neurological function and high sensitivity C reactive protein (hs-CRP) in serum in patients with acute cerebral infarction. Methods 90 patients with acute cerebral infarction were divided into three groups: drug, routine acupuncture and resuscitating acupuncture and scalp acupuncture groups in random. They were evaluated with NIH Stroke Scale (NIHSS) , Modified Rankin Scale (MRS) 0, 7, 14 d after treatment, and measured with the levels of hs-CRP. Results There were significant improvements for NIHSS and MRS scores in the resuscitating acupuncture and scalp acupuncture group compared with those of the others, as well as the levels of hs-CRP. Conclusion Resuscitating acupuncture and scalp acupuncture can reduce the level of hs-CRP and improve the neurological functions in patients with acute cerebral infarction.

AIM: To investigate the signaling mechanisms involved in the priming effects of lipopolysaccharide(LPS) on heat killed Staphylococcus aureus(HKSa)-induced nitric oxide(NO) production in macrophages.METHODS: Murine macrophage RAW264.7 was used in the experiment.Griess reagent was used to measure the content of nitrite in culture medium.Real-time PCR and Western blot was utilized to examine the mRNA and protein levels of toll-like receptor 2(TLR2),respectively.Dual luciferase reporter assay was used to assess the transcriptional activity of nuclear factor of activated T cells(NF-AT).RESULTS: The RAW264.7 cells pretreated with LPS for 24 h significantly enhanced NO production induced by HKSa,suggesting that LPS primed the macrophages and increased the reactivity of the cells to HKSa.LPS increased the mRNA and protein levels of TLR2 in a dose-dependent manner in RAW264.7 cells.The RAW264.7 cells pretreated with LPS enhanced NO production induced by peptidoglycan,one of the specific ligand of TLR2.The priming effect of LPS on HKSa-induced NO production was partly blocked by TLR2 neutralizing antibody.LPS significantly enhanced the transcriptional activity of NF-AT,which was inhibited by BAPTA/AM(a cell-permeable cytosolic calcium chelator) and cyclosporine A(CsA,an inhibitor for calcineurin).Both BAPTA/AM and CsA inhibited the priming effect of LPS on HKSa-induced NO production in RAW264.7 cells.CONCLUSION: The present study confirms the priming effect of LPS on the reactivity of RAW264.7 cells to HKSa.Pattern recognition receptor TLR2 and calcium/calcineurin/NF-AT signaling pathway may be involved in the priming process initiated by LPS.

Objective To observe the effects of a motor relearning programme (MRP) combined with different early acupuncture interventions on muscle tension and motor function recovery after cerebral infarction.MethodsA total of 90 patients with cerebral infarction who met the inclusion criteria were divided into three groups at random:a YANGMING meridian acupuncture and MRP group ( group A),an anti-spasm acupuncture and MRP group ( group B),and an MRP group ( group C ).All of the patients in all three groups were treated with routine medication.The National Institute of Health stroke scale (NIHSS),the composite spasticity scale (CSS),Fugl-Meyer assessment (FMA),the Fugl-Meyer balance scale (FM-B) and the modified Barthel index (MBI) were used to measure performance before treatment and after 4 weeks of treatment.Another comparison was intra-group between before and after treatment. ResultsThere were significant differences in the assessment results in all of the groups after treatment compared with those before treatment.After treatment,group B was superior to group C only in terms of NIHSS scores.There was no significant NIHSS score difference between groups A and C.The FMA,CSS and MBI results revealed significant differences among all three groups,with the scores of group A consistently the highest.The average FMA score in group B was significantly higher than in group C but there was no statistically significant difference in FM-B scores among the three groups. ConclusionMRP therapy combined with early acupuncture intervention can improve motor function and muscular tension after cerebral infarction.Anti-spasm acupuncture can improve motor function and control muscular tension effectively at the same time,making it beneficial for MRP training.
