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 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.

Objective: To observe the effect of puncturing Juliao (GB 29) in treating carpal joint sprain. Methods: 99 cases were randomly divided into 3 groups, treatment, control 1 and control 2 groups, 33 cases for each group. Cases in treatment group were treated by acupuncture on Juliao (GB 29); patients in control 1 group were treated by acupuncture at Sanyinjiao (SP 6), and patients in control 2 group were treated by local application. The clinical effect was compared among three groups after the treatment. Results: The effective rate in the treatment group is 96.9%, which is over and above 84.8% in control 1 group and 75.8% in control 2 group (both P＜0.05). Conclusion: Acupuncture at Juliao (GB 29) has a precise curative effect in treating sprain of carpal joint. It is more effective than acupuncture at Sanyinjiao (SP 6) and local application.

The pulmonary surfactant protein D ( SP-D) plays an important role in host defense and innate immunity of the lung.It has increasing evidences that SP-D involves in the pathogenesis of respiratory syncytial virus (RSV)infection.Recent studies have demonstrated that SP-D can be used for treating infectious and inflammatory diseases of the lung .Here is to make a review on SP-D structure, function , relationship between RSV and pulmonary inflammatory disease treatment .aiming to provide some assistance for treatment of RSV infection .

The health check-up results of 11 514 subjects in 2011 at Beijing Hospital were retrospectively analyzed,including the results of 13C urea breath test for detection of Helicobacter pylori (Hp) and HbA1c test.The results showed that the prevalence rate of Hp infection was significantly higher in females (31.77％) than that of males (29.36％) (x2 =7.355,P ＜0.05) ; the highest prevalence was found in 35-60 y age group (31.17％).Hp positive rates in subjects with body mass index (BMI) ≥28kg/m2 and central obesity were 31.55％ and 30.44％,respectively; there were no significant differences from those with normal weight and non central obesity.Subjects with positive Hp infection had higher levels of HbA1 c,compared to those with negative Hp infection (t =-2.276,P =0.01).In subjects with BMI ≥24 kg/m2 and central obesity,HbA1c level was higher in Hp positive subjects than that in Hp negative ones (P ＜0.05).Diabetes mellitus was positively associated with Hp infection (OR 1.282; 95％ CI 0.941-1.799),particularly in obese patients (OR 1.459 ; 95 ％ CI 1.070-2.071).The results indicate that Hp may be involved in the impairment of glucose regulation,particularly in those with higher body mass index.
