Objective To establish the training objective systems for undergraduates in mili-tary clinical medicine in order to promote the educational reform of military medicine, and to improve the quality of talents training in military medical universities. Methods Literature analysis was made to determine the initial military clinical medical undergraduate training objectives, and a questionnaire was given to experts, on-the-job military doctors, medical graduates to know the real requirements of military doctors' position. A total of 455 valid questionnaires were collected. Then the questionnaire results were discussed and summarized by the method of expert discussion. Finally,. Delphi method was used to determine the ultimate training objective system. Results The ultimate training objective system of military undergraduate clinical medicine contains two aspects, eight fields and sixty-one standards objective systems. Conclusion Organically fusing military medical knowledge, ability and professional quality requirement into two levels and eight modules and clearly understanding the standards and requirements of each module are significantly systematic, advanced and operable, which has important reference value and guiding significance to both the military medical colleges and uni-versities and the local universities.

AIM: To determine the relevance of NADPH oxidase subunit p22hox and the expression of superoxide anion on ventricular remodeling in myocardial infarction (MI) rats. METHODS: MI of Sprague-Dawley rats were established by left anterior descenting coronary artery ligation. 8 weeks after MI, Doppler echocardiography, hemodynamic study and histomorphometry were performed to analyze the ventricular remodeling. The level of thiobarbituric acid reactive substance in plasma and myocardium were measured, and the distribution of superoxide anion was observed with laser scanning confocal microscope. The expression of p22phox mRNA and protein level was detected by RT-PCR and immunohistochemistry. RESULTS: The left ventricular remodeling was significant in MI rats, also the level of thiobarbituric acid reactive substance increased in the plasma and non-infarcted myocardium. The expressions of p22-phox mRNA and protein levels, and superoxide anion increased in infarcted and non-infarcted myocardium in MI rats. CONCLUSION: Our results suggest that the expression of NADPH oxidase and its derived superoxide anion may take part in left ventricular remodeling through oxidative stresss after MI.

Objective:To study the metabolism of pedunculoside treated with rat intestinal bacteria in vitro. Methods:Pedunculo-side and rat intestinal bacteria were incubated in vitro for 0, 4, 8, 24 and 48 hours under anaerobic condition. After extracted repeat-edly by ethyl acetate, the metabolites in the incubation media were qualitatively and quantitatively analyzed by HPLC. Results:Totally 90. 8% of pedunculoside was transformed to M2 after incubated with rat intestinal bacteria in vitro for 48 hours, and a detailed compari-son of HPLC profiles between M2 and rotundic acid showed M2 was rotundic acid. Conclusion: Pedunculoside can be metabolized to rotundic acid by rat intestinal bacteria in vitro.

Objective To analyze the ophthalmologic characteristics and examinations which caused by vertebral-basilar insuffi- ciency.Design Retrospective case series.Participants 469 eases of vertebral-basilar insufficiency.Methods Retrospective analysis of 469 cases of vertebral-basilar insufficiency patients with ophthalmologic signs' features,incidence,the main cause,color Doppler flow imaging and(or)digital subtraction angiography clearly stenosis location,the degree of stenosis from July 1st 2005 to July ist 2007 in PLA General Hospital.Main Outcome Measures Ophthalmologic signs' related reasons and supplementary examination.Results 96 cases were with the corresponding eye symptoms(20.4%).Vision decreased in 83 cases,diplopia was in 56 cases,ipsilateral hemiopia quadrant blind in 12 cases and depending on deformation in 10 cases,fundus arteriosclerosis in 72 cases,nystagmus in 39 cases,the eye movement disorder in 16 cases.Among 96 patients with associated ocular symptoms,75 patients with color Doppler flow imaging (CDFI)showed unilateral vertebral artery abnormal in 66 cases(88%),among those blood flow velocity decreased in 26 cases,17 cases with vascular plaque stenosis,thinning in 20 cases,3 cases with complete occlusion;different bilateral vertebral artery abnormal in 9 cases(12%),among those velocity dropped in 4 cases,two cases with vascular plaque stenosis and thinning in 3 cases.Forty-five cases with the digital subtraction angiography(DSA),left vertebral artery was abnormal in 24 cases,18 cases with stenosis,occlusion in 5 cas- es,abnormal bending in 1 case.Right vertebral artery was abnormal in 16 cases,13 cases with stenosis,occlusion in 3 cases.Bilateral vertebral artery stenosis was found in 2 cases;vertebral artery stenosis was in 3 patients.Conclusion Vertebral-basilar insufficiency may cause eye-related symptoms,therefore,vision acuity decrease,fundus 'arteriosclerosis,diplopia and nystagmus symptoms are more likely for patients with vertebral-patients with basilar artery insufficiency performance of the eye.(Ophthalmol CHN,2002,16:406-410)

Objective: To understand the effect of dobutamine on the integrated backscatter of myocardium. Methods: Nineteen open-chest dogs were detected by HP Sonos 5500 with S8 transducer, and the WT, AIBS and CVIB were measured before and after the dobutamine stress. Results: During the dobutamine stress, following the increase of WT, the transmural, subepicardial and subendocardial CVIB all increased. And the increase of subepicardial CVIB was greater than that of subendocardial CVIB, leading to the decrease of TGI. But the AIBS didn't change significantly in the whole process. Conclusion: Dobutamine can enhance myocardium CVIB but has no obvious infleunce on AIBS.

Objective To explore the clinical,radiological findings and pathogenic factor of spondylometaphyseal dysplasia.Methods Five cases were reported and the relevant documents were studied retrospectively.Plain X-ray film was performed in all patients.Results There were 4 male and 1 female,age ranged from 4 to 15 years with average of 9 years.The main features of 5 cases included delayed bone age,stature short,short trunk,waddling gait noted,scoliosis in 2 cases,kyphoscoliosis in 1 case,severe genu valgum in 2 cases.The main X-ray appearance of 5 cases is multiple irregularities of long bones metaphyses associated with platyspondylia,epiphysis is normal.Type Ⅰ SMD in 2 cases,Type Ⅱ SMD in 1 case,Type Ⅲ SMD in 2 cases.Conclusion When we meet children with delayed bone age and stature short,and muhiple irregularities of long bones metaphyses associated with platyspondylia were seen in X-ray plain film.we should think about spondylometaphyseal dysplasia.

Traditional Chinese medicine is a treasure of Chinese culture, absorbing the wisdom of the Chinese people. Continuous application of new technologies makes traditional Chinese medicine research advance with the times. After several years of development, high-throughput transcriptome study has become a mature research tool in biology. This paper reviewed the advances in medicine transcriptome study, and compared two sequencing platforms, Roche's GS FLX platform and Illumina's HiSeq 2000 platform. Moreover, this paper introduced medicine transcriptome analysis process, with Panax quinquefolius and Lonicera japonica for examples, showing the characteristics of traditional Chinese medicine transcriptome studies. High-throughput transcriptome studies facilitate traditional Chinese medicine research with overall understand of functional genes, give clear elucidation of metabolic pathways, lay molecular foundation for the traditional Chinese medicine research and offer modern interpretation for traditional Chinese medicine theory. However, the current study faces several difficulties, including weak molecular basis, high sequencing cost and staff shortages in data anaysis. In the future, with the development in sequencing technology, the combination of transcriptome and other genomics, such as proteome and metabolome, will lay a solid foundation for the new high-throughput screening and developing model for the traditional Chinese medicine industry.
