Body surface mapping is introduced in this paper. The research of bodysurface mapping involves two main aspects :data acquiring system and data processing methods. The recommended design applies the virtual instruments concept and high speed open bus standard. The data processing methods involve qualitative and quantitative methods. Dynamic and static mapping techniques are introduced as the qualitative methods. Statistical methods,inverse calculation and principle component analysis are introduced as the quantitative methods.

Physiological and biochemical characteristics,drug sensitivity of pathogenic bacteria isolated from the diseased Sparus latus in Zhanjiang,Guangdong,and inactivated whole cell vaccine were studied.The results show that the isolated strain is Vibrio alginolyticus and is highly sensitive to tetracycline,gentamycin,chloramphenicol,and so on.But it is not sensitive to erythromycin and penicillin K.It also shows that the pathogen is inactivated more easily at pH6.0 than at pH8.4 when formalin is used.The whole cell vaccine can strengthen Sparus latus's immuno function and lessen their death rate when fish are infected by the Vibrio alginolyticus.

Objective To investigate the morphological difference of spinal single vertebral tuberculosis and metastasis by means of CT.Methods CT features of 16 cases of single vertebral tuberculosis and 17 cases of single vertebral metastasis which were proven by clinically and/or pathology, were retrospectively analyzed,and then the CT differential criteria of the two categories of diseases was recommended.Results The reliable CT findings for vertebral tuberculosis were as follows: involvement of anteriomedial potion of vatebral body,presence of sequstra in lesion ,marginal sclerosis in the edge of lesion,calcification within paravertebralmass or abscesses ,only edge enhancement of more of paravertebralmass.Metastasis was characterized by involvement of posteriomedial portion of vertebral bone,absence of sequestra within lesion ,no calcification within paravertebralmass.Both of them had normal intervertebral disc.Conclusion The different CT features of the single vertebral tuberculosis and metastasis are helpful in differerntiating diagnosis ,the morphological change of intervertebral discs is not helpful in differerntiating diagnosis .

Objective To observe the safety and efficacy of FOLFOX4 regiment in elderly versus young patients with advanced colorectal cancer. Methods There were 61 patients enrolled in this study, with 28 elderly patients aged 70 years and over, 33 young patients aged less than 70 years.They suffered from advanced/recurrent colorectal cancer and received FOLFOX4 regiment (Oxaliplatin +CF+5-FU). Every 14 days were as a cycle, and the therapeutic safety and efficacy were evaluated after three cycles. Adverse events and response to treatment were compared between the elderly and young patients. Results The main adverse effects were myelosuppression, gastrointestinal disturbance and neurotoxicity. The incidence rate of diarrhea was significantly higher in elderly patients than in young patients, but the most of diarrhea were at grade Ⅰ - Ⅱ. The incidence rates of leucocyte decrease and neutrophil decrease were higher in elderly patients than in young patients (92. 8% vs. 78. 8%, 39.3% vs. 36.3%), but there were no statistically significant differences between them. The incidence rate of neurotoxicity was 46.5% in elderly patients and 36.4% in young patients (P＞0. 05). The recent efficacy rate was 25%, disease control rate was 71.4% and median time-to-progression (TTP) was 6 months in elderly patients and 24.2%, 84.8% and 7 months in young patients (all P＞0.05). Conclusions FOLFOX4 regiment is well-tolerated and effective in both young and elderly patients.

Objective To evaluate the feasibility and safety of percutaneous transluminal angioplasty(PTA)using ? 30 mm balloon catheter to dilate the obstructive lesion of inferior vena cava(IVC)in Budd-Chiari syndrome(BCS). Methods From January 2002 to July 2006,146 consecutive patients with BCS(94 men,52 women)underwent color Doppler sonography including enhanced multislice CT(n = 47),and were confirmed by IVC angiography. All patients but 1 microsomia case were treated by PTA using ? 30 mm balloon catheter for dilation. IVC angiography were immediately performed to show patency of IVC and occurrence of any rupture or not after PTA. Follow-up color Doppler sonography was taken to evaluate the IVC patency and the PTA-related complication about 1 week after PTA. Results The mean transversial and longitudinal diameters of IVC at the junction level of right atrium and IVC were(25.09 ? 6.09) mm and(17.57 ? 3.93) mmrespectively in 46 cases with 3 D multi-slice CT preoperatively(1 case without measurement was due to the closest site with right atrium). There were no IVC rupture during the procedure. Conclusions Treatment of BCS by PTA using ? 30 mm big balloon catheter is feasible and safe.

Objective To investigate the regulative effect of interferon gamma (INF?) on the expression of platelet-derived endothelial cell growth factor / thymidine phosphorylase (PD-ECGF/TP) and its relation with the anti-cancer effect of 5′-deoxy-5-fluorouridine (5'DFUR) and 5-fluorouracil (5FU) in T24 bladder cancer cells. Methods PD-ECGF/TP mRNA and protein expressions were determined by RT-PCR and Western blot,respectively.Cytotoxicity of 5′DFUR,5FU or mitomycin C (MMC) against T24 cells was evaluated by MTS assay. Results The expressions of PD-ECGF/TP mRNA and protein were concomitantly elevated in T24 cells after INF? treatment.And INF? decreased IC 50 s of 5′DFUR [from (16.0? 3.6 )mmol/L to (6.2?0.9)mmol/L,( P

Objective: To study the difference in tooth profile among Chinese,Caucasian and Japanese with normal occlusion.Methods: The data of the measurments of Chinese,Caucasian and Japanese with normal occlusion were collected from published studies.Crown angulation,crown inclination and crown convex were used in the comparation among the peoples. Results: Tooth profile in Chinese was significantly different from that of Caucasian but was similar to that of Japanese. Conclusion: The orthodontic appliances should be modified when we use the straight wire appliances that is suitable for Caucasian and Japanese.

Objective To investigate the relationship between the genetic variation of leptin receptor and obesity in Chinese population. Methods Genomic DNA was extracted from 50 obese subjects 〔Body mass index (BMI)≥30 kg/m 2〕 and 50 normal individuals (BMI

Objective To find out nutrient support drug utilization in cancer patients in our hospital. Methods An analysis was made by means of drug utilization research into the structure and rationality of nutrient support drug utilization in our hospital through an investigation into the detailed records of the dispensary from 1999 to 2002 and into 1 014 medical records from 2002. Results The variety, quantity, and cost of nutrient support drug utilization in the four years rose respectively by 58.82%, 71.66% and 28.16%. 49.30% of the cancer patients whose medical records were surveyed used such drugs. The quantity and person time ratio of PN and EN drug utilization was respectively 14∶1 and 13∶1, with malnourished patients accounting for 19.80%. Of the PN drugs whose DDD value could be determined, most had a DUI value that was greater than 1 whereas most of the EN drugs had a DUI value which was smaller than 1. Conclusion The variety, quantity, and cost of nutrient support drug utilization in the four years rose rapidly. The quantity and person time of PN drug utilization were much higher than those of EN drug utilization. Doubts could be cast in the handling of indications for nutrient support drug utilization in some patients and the doses of some nutrient support drugs prescribed were not so rational. Further explorations need to be made into the rational application of nutrient support treatment.
