Taking the teaching process of the medical immunology curriculum as a master line,the curriculum restructuring as the method and the big sample investigation results as the basis,this article advocates teaching with heart,establishing curriculum with the sentiment,in order to interlink the heart of teachers and students and reach mutual understanding.

Objective To evaluate the clinical utility of ROI(region of intest)volume measurement for interventional embolization of the oral and maxillofacial AVM before intervention.Methods four patients with oral and maxillofacial AVM were undertaken,ROI volume measurement of AVM by GE AW 4.1 software based on the MRI and MSCT imaging data,and the quantity of embolic agent was administered correspondingly to the measured volume of AVM lesion and then,the therapeutic effect was observed.Results In 3 cases of this series,the volume of AVM lesions obtained by ROI volume measurement based on the imaging data were 7.515 cm3,1.195 cm3 and 10.714 cm3,respectively;gaining all the therapeutic satisfactory effects.However,the volume of the other case was not achieved because of the bilateral diffuse AVM with previous ligation of feeding arteries.Conclusions Soft tissue AVM can be best demonstrated on MRI and MSCT therefore can display AVM of jaw clearly.Pre-embolization of oral and maxillofacial AVM,the quantity of embolic agent(especially the liquid agent) can be estimated correctly by the ROI volume measurement used GE AW 4.1 software.

Objective To compare the transcatheter hepatic arterial chemoembolization(TACE) combined percutaneous ethanol injection(PEI)in treating primary hepatic carcinoma and the simple TACE treatment. Methods 64 primary hepatic carcinoma patients were divided into union treatment group(n = 32)and TACE group(n = 32),with TACE combined PEI treatment and simple TACE treatment,respectively. The tumor size,AFP change,one year,two years,three years survival time and median survival time were observed and recorded during the course of treatment. Results The tumor shrinkage rates and the AFP transferring into negative rates of the union and simple TACE groups were 84.4%,62.7% and 77.4%,50% respectively after the treatment with significant difference between the two groups. The 1 years,2 years,3 years and median survival rates of the union and simple TACE groups were 96.9%,71.9%,37.5%,34.5 mo and 81.3%,31.3%,12.5%,19.5 mo,respectively,showing conspicuously significance of both groups. Conclusion TACE combined PEI for primary hepatic carcinoma is a better treatment of choice.

Objective To compare the effects of transabdominal hysterectomy(TAH),transvaginal hysterectomy(TVH),and laparoscopic assisted vaginal hysterectomy(LAVH).Methods Clinical data of 48 cases of TAH(TAH Group),38 cases of TVH(TVH Group),and 31 cases of LAVH(LAVH Group) were retrospectively analyzed.Results The operation time was shorter in the TAH Group(73.7?5.9 min) than in the TVH Group(80.9?7.0 min) and the LAVH Group(129.3?9.1 min)(F=612.04,P=0.000).The intraoperative blood loss was greater in the LAVH Group(142.8?17.1 ml) than in the TAH Group(128.1?9.6 ml) and the TVH Group(129.7?10.2 ml)(F=15.18,P=0.000).The postoperative analgesic requirement rate was higher in the TAH Group(75.4%,36 cases) than in the TVH Group(30.2%,11 cases) and the LAVH Group(38.4%,12 cases)(?~2=20.310,P=0.000).The length of postoperative hospitalization was longer in the TAH Group(7.3?1.6 d) than in the TVH Group(4.8?1.0 d) and the LAVH Group(5.1?1.1 d)(F=47.07,P=0.000).The postoperative pyrexia rates were not significantly different among the TAH Group(8.4%,4 cases),the TVH Group(7.4%,3 cases),and the LAVH Group(8.2%,3 cases)((?~2=0.074,) P=0.964).Conclusions As compared with transabdominal hysterectomy,transvaginal hysterectomy and laparoscopic assisted vaginal hysterectomy show advantages of less invasion,less pain,and quicker recovery.

Objective　To research the compliance in the treatment rehabilitation of outpatients with schizophrenia Method　The compliance of 415 cases of schizophrenia were evaluated by face to face interview, and their genaral populations data,antipsychotics use situation,factors affecting compliance were collected by comprehensive interview.The corretaled factors were also analysised.Achi-square statistic was used.Results　Among all the enrolled cases,55.9% were fully compliant,23.6% partially compliant and 20.5% non-compliant.Factors affecting compliance were ages,dosage,famillies-environment relationship and personality.Conclusions　It is necessary to increase compliance in the treatment rehabilitation of schizophrenia.In this way,the effect can be strengthened and the relapse in rehabilitation can be decreased.

Objective:To evaluate the diagnostic value of KaVo DIAGNOdent(DD)by comparing the diagnostic results of visual examination(VE)and stereomicroscope.Methods:The occlusal surface of 68 extracted teeth were examined by DD and VE,confirmed the examining points and marked,then cut these teeth along the markers.The results of stereomicroscope were classified into D0,D1,2,D3,4 according to the occlusal caries' depth,and recognized as gold standard.The difference of sensitivity,specificity between VE and DD,and their coherence were analyzed.Results:Sensitivity of DD,in D3,4 level of occlusal caries,was the highest.Compared to the results of stereomicroscope,the accuracy of DD and VE was the highest in D3,4 level.The coherence of DD and VE was low in all levels.Conclusion:The present cut-off point of DD affects the assessment of DD diagnostic result.Future study about key points of diagnosis of DD can widen its use in clinic.

Objective To study the effect of sub-clinical dosage of EPO on early renal lesions of diabetic rats. Methods The rats were randomly divided into normal control group (NC), diabetic group (DM), diabetic rats treated with A-dosage EPO (DMTA), and diabetic rats treated with B-dosage EPO (DMTB). Diabetic rats induced by STZ were given EPO intraperitoneally for 10 weeks; then blood glucose, blood pressure, renal function indexes, renal morphological parameter, the expression of cell apoptosis associated protein Bcl-2/Bax and VEGF were measured. Results After treatment of EPO, renal functional and morphological indexes were improved significantly and the ratio of Bcl-2/Bax and VEGF increased, both in a dose-dependent manner. Blood sugar, blood pressure and hemoglobin concentration had no significant differences. Conclusion Sub-clinical dosage of EPO could play an advantageous role in diabetic nephropathy. Inhibition of cell apoptosis by upregulation of Bcl-2/Bax expression rate may be responsible for renal protective effects despite the upregulation of VEGF.
