In the background of the crisis of doctor-patient relationship and the effectiveness of medical humanities education doubts we need to think about how to achieve,transform and reflect the value of doctors' understanding on their professional meaning,how to realize the functional significance of doctorpatient cooperation and how to make doctors put themselves in patients' place by the curriculum and its operating mechanism.This paper discussed the external environment and the microcosmic environment from the externality and connotation of the humanities curriculum.And the way to reflect and achieve the value transformation of the medical humanistic curriculum in the mechanism of education was considered.This paper put forward combining the institutional mechanism of policy leading,the subject mechanism that is the basis of the curriculum,the constitutive mechanism of curriculum system and the cultural mechanism to make students study and internalize,and made some suggestions.

Objective To study the effect of specific immunotherapy (SIT) with purified humulus pollen allergens for asthma patients. Methods The humulus pollen allergens were purified partially by gelatin filtration. A double-blinded study was carried out. Eight-six patients with seasonal humulus pollen allergic asthma were divided randomly into two groups: observation group (group A) and control group (group B), which were administered SIT with purified or crude humulus pollen allergens, respectively, before the allergic season for half a year. The clinical effect and side effects were observed. The laboratory observation norms included T lymphocyte subpopulation, the wheals’diameter of IT, the average index of HBDT and the specific IgE before and after SIT . Results The general effect of SIT with purified allergens in group A was 90.7% (39/43), and that with crude allergens in group B was 79.1% (34/43) (P

Objective To purify and identif y Platanus acerifoli wild pollen. Methods We carried out intracutaneous test with Platanus pollen extract in 30 patients with allergic as thma who visited our hospital from March to May 2003. Seven subjects who had bee n diagnosed as having Platanus pollen-induced asthma were enrolled. Platanus po llen proteins were separated by gel filtration with Sephadex-G-100. To charact erize allergenic components, Platanus pollen extract was analyzed by means of so dium dodecylsulfate-polyacrylamide gel electrophoresis followed by immunoblotti ng. Results To purity the pollen we separated Platanus poll en extract in a first purification step by using gel filtration with Sephadex G -100. Two elution peaks were observed. Twelve percent SDS-PAGE analysis showed more than 10 protein bands whose molecular mass (Mr) ranged from 16 ku to 71 ku. Six bands abundant with protein at 71, 50, 35, 39, 22 and 16 ku were observed. On SDS-PAGE, the proteins of the first peak whose Mr we re 71, 50, 35, 39, and 22 ku and that of the second peak was 16 ku. SDS-PAGE and IgG-immunoblotting analysis with seven sera showed 4 IgG-binding component s whose Mr was 50, 39, 22 and 16 ku. The protein bands whose Mr was 50 ku and 22 ku had the highest binding capacity. Conclusion The strongest activity exists in the first peak which can be the major sensiti zing components and there is mild allergic activity in the second peak which is the minor sensitizing components.

AIM: To understand whether reactive oxygen species promote the rupture of atherosclerotic plaques by regulating the balance of matrix metalloproteinase-1,3 (MMP-1,3) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in smooth muscle cells. METHODS: Aortic smooth muscle cells from 4-6months-healthy abortive fetuses were incubated for 24 hours with xanthine (100 ?mol/L) and xanthine oxidase (5 U/L) in vitro . MMP-1,3 and TIMP-1 in the concentrated culture media were measured by Western blotting ( n =3 independent experiments). RESULTS: Incubation with xanthine/xanthine oxdiase decreased the amount of MMP-1 in the aortic smooth muscle cells (21.2%?5.5% of the control group),and pro-MMP-1 was activated completely. Reactive oxygen species (ROS) also activated pro-MMP-3,and increased the production of MMP-3 in the aortic smooth muscle cells. On the other hand,ROS inhibited the production of TIMP-1 in the aortic smooth muscle cells. CONCLUSION: It is complicated that ROS regulates the balance of MMPs and TIMPs. ROS may contribute to matrix degradation and the rupture in the atherosclerotic plaques.

Objective To investigate the therapeutic effects and adverse drug reactions of different doses of rosuvastatin in patients with acute ST segment elevation myocardial infarction (STEMI). Methods A total of 115 patients with STEMI were collected from Department of Cardiology, the Second Hospital of Tianjin Medical University. According to different oral doses of rosuvastatin, patients were divided into two groups including 5 mg/d rosuvastatin treatment group (low-dose group, n=44) and 10 mg/d Rosuvastatin treatment group (moderate-dose group, n=71). Patients of two groups were treated with Rosuvastatin at least 1 month after discharge. Data of total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed and compared before and after treatment between two groups. The major cardiovascular adverse events (MACE) and adverse reactions were recorded in two groups of patients. Results There were no significant differences in blood lipid and liver function levels before and after one month treatment between the two groups. After one month treatment, levels of TC, LDL-C, ALT and AST were significantly decreased in both groups of patients compared with those before treatment (P<0.05). There were no significant differences in levels of TG, and HDL-C before and after treatment between two groups. The incidence of MACE (heart failure and angina pectoris) was significantly lower in moderate-dose group than that in low-dose group (P<0.05). There was no significant difference in the proportion of malignant arrhythmia between the moderate-dose group and the low-dose group (P<0.05). No target vessel repair and death were found in the two groups. No obvious adverse drug reactions were found during the follow-up period. Conclusion The hypolipidemic effects are epuivalent between 5 mg/d rosuvastatin and 10 mg/d on the basis of conventional treatment for STEMI patients, but the moderate dose can reduce the incidence of MACE and improve prognosis.

OBJECTIVE: To explore the methods to detect and intervene children's late-onset hearing loss early which are suitable for basic-level hospitals. METHOD: Udiology and imaging diagnosis had been given to the children who passed the newborn hearing screening but showed auditory behavior disorders in the growth process, and individualized interventions were given according to the results of diagnosis. Seven children with high risk for hereditary deafness were sent to superior hospital and had molecular screening of common mutations of inherited deafness carried out, then corresponding prevention guidance and intervention were given to them. RESULT: Fifty-two cases with late-onset hearing loss or verbal disorders were detected by auditory behavior observations,including 4 cases of auditory neuropathy, 4 cases of unilateral sensorineural deafness, 27 cases of secretory otitis media. 13 cases of bilateral sensorineural deafness and 4 cases of autism. Seven newborns with high risk of hereditary deafness were sent to the Third Affiliated Hospital of Sun Yat-Sen University and received molecular screening of common mutations of inherited deafness. One case with GJB2 compound heterozygous mutations was detected and followed up to 4 years old, he was found bilateral moderate hearing loss and accepted the hearing aids at 2 years old. Mitochondrial DNA 1555 a > G heterogeneity mutation in 2 cases and GJB2 235 delC single heterozygous mutations in 3 cases, no mutation in 1 case, all these 6 cases have been followed-up until now, their hearing are normal. CONCLUSION Children's auditory behavior observations and the superior hospitals referral performing high risk individual screening for newborns with high risk for hereditary deafness can detect children's late-onset hearing loss in time, this model is suitable for basic-level hospitals.
