To study the effect of physical fitness exercise prescription on the cardiac function of collegians, three different exercise prescriptions on the collegians extra-curriculum exercises to develop their strength, cardiac function and overall physical fitness separately and one control were applied. The results show that after 8 weeks training, the rest HR of all exercise groups decreased while SV(stroke volumn), SI (stroke index), CO (cardiac output)and CI (cardiac index) increased significantly. Furthermore, the results also show that VPE (ventricular pumping effectiveness) and VPEI (ventricular pumping effectiveness index) of exercise groups increased while MSP(mean systolic pressure), MDP(mean diastolic pressure) and MAP (mean arterial pressure) decreased at variant degree. From the study it is not difficult to see that doing exercise prescription can develop the collegians' cardiac-function significantly. Comparing these three exercise prescriptions show that doing endurance exercise prescription can get the best effect on developing the cardiac-function, but doing the comprehensive-developing exercise prescription can get more comprehensive effect on cardiac and vascular function. Another result from comparing the control group shows that the females are easier to get the physiological function descent than the males if they do not do exercises actively. In conclusion, it is worth to extend physical fitness exercise prescription in collegians' extra-curriculum exercise because of the simple condition, scientific method and significant effect.

With the success of the human genomic project, the amount of experimental data is increasing rapidly. In the post-genomic era, the focus is now shifting to the so called "from the sequence to the function", i.e., in addition to completing genome sequences, it is possible to learn about gene expression patterns and protein interactions on the genomic scale. Description and analysis of complex Genetic Regulatory Networks (GRN) is a critical problem for biologists to understand genetic regulatory mechanism. Most of existing methods ignore the synergistic effects observed widely in biologic systems. Thus there should be some errors between the predictions of the model and the actual biologic behaviors. To address this problem, a new quantitative analysis approach for genetic regulatory networks was proposed in the context of Hybrid Functional Petri Net (HFPN). Firstly, basic theory of GRN and HFPN was presented briefly. Petri-net-based models have been widely adopted for studying biological systems since Petri net has graphical modeling representation and strict mathematic background. In GRN, the combined effect of transcription factors to induce or repress gene transcription is usually different from the simple sum of their individual effects. This is so called Synergistic effect. Two kinds of new elements, logic places and logic transitions were introduced to describe the logic rules in GRN and the synergy between transcription factors. It was decided to extend existing tools instead of writing new software in order to have more time for the experimental part of this project. A Petri Net Workbench was developed based on the Open Source project the Petri Net Kernel (PNK) and the Systems Biology Workbench (SBW) during this project. The Petri Net Workbench was extended by the following features: the extended definition of Hybrid Functional Petri Net, the Ordinary Differential Equations (ODEs) solver, Systems Biology Markup Language (SBML) support and time course simulation. Finally, a Petri net model for the genetic regulatory network of the sea urchin endo16 gene was developed base on the GRN model published in literature and a list of quantitative outputs for different mutations was predicted. The analysis result corresponded to the experimental data published in literature properly and demonstrated the correctness of the Petri net model. It demonstrated how Hybrid Functional Petri net analysis techniques can be applied to Genetic Regulatory Networks. The new concepts of logic places and logic transitions had been proven to be useful for describe the logic rules in GRN and the synergy between transcription factors.

Objective To study the values of the diagnosis of superficial carcinoma of stomach using digital radiography(DR). Methods Patients with superficial carcinoma of stomach( n = 62) were divided into two groups:group DR( n = 35, using digital radiography) and group control( n = 27, using traditional X ray machine). All pa-tients were undergone Gas-Barium double contrast radiograph examination before operation and confirmed by pathol-ogy. Results In group DR, the focuses of 32 patients were found and 3 lost. In group control, the focuses of 22 pa-tients were found and 5 lost. The detection rate of the two groups had significant difference( P < 0.01 ). Conclusion The application of DR could increase the detection rate of superficial carcinoma of stomach, meanwhile gastroscope and pathology biopsy were also important.

Objective To observe the characteristic features of musculoskeletal ultrasound (MSUS) in gouty arthritis (GA) and to assess its value in GA diagnosis.Methods Patients with GA and non-GA who underwent MSUS examination in Chinese PLA General Hospital were enrolled in this study. The synovitis,tenosynovitis,soft tissue swelling,bone erosion,bursitis and ossification were measured by greyscale ultrasound,and the synovial vascularity was measured by power Doppler ultrasound to evaluate the degree of inflammation.Results The ultrasound images of GA were intended to have specific features like tophus,hyperechoic deposition on the surface of the articular hyaline cartilage ( double contour sign ),hyperechoic deposition in the synovium appearing as bright stippled foci,and bright strap in tendons with a significant difference when compared with non-GA group (P ＜ 0.05).The percentage of tenosynovitis and bone erosion in non-GA group was higher than that in the GA group with a significant difference (P ＜0.05 ). Tophus,double contour sign,bright stippled foci or bright stippled foci in tendons together suggested gout with a specificity of 92.4％ and a sensitivity of 60.3％,the AUC of ROC was 0.764 ( P ＜0.05).Conclusion Tophus,double contour sign,bright foci and bright strap detected by MSUS are of diagnostic value on GA and MSUS may be a promising tool in diagnosing GA.

OBJECTIVETo investigate the clinical application of pedicled superficial circumflex iliac artery (SCIA) flaps in Burns and Plastic Surgery.

METHODS19 cases with skin and soft tissue defects were repaired with the Superficial circumflex iliac artery flaps. The defects located in the hand and forearm, the lower abdomen and perineal area, the radicle area of thigh, etc. Before the SCIA flaps were transfered to the recipient areas, 15 cases with different kinds of wounds were debrided thoroughly, 3 cases with scar were removed directly. The size of the flaps ranged from 3.0 cm x 4.5 cm to 26.0 cm x 22.0 cm, and the pedical was 5 cm to 7 cm in length.

RESULTSThe flaps in the 18 cases survived completely. Skin necrosis in the distal end of the flap appeared in 1 case, and the wound healed after the second repair. The follow-up period rang from 3 to 18 months. The apperance and function of the hand or foot was satisfactory.

CONCLUSIONSBecause the pedicled SCIA flaps can be obtain conveniently and contain sufficient blood-supply, so the flap is easy to survive and the flap can be designed in a large size. We believe it is an ideal method to use this flap to repair skin and soft tissue defects located in hands, forearms, the lower abdomen and perineal areas, the radicle area of thigh and so on.
