Objective To evaluate the role of imaging diagnosis in surgical treatment of primary aldosteronism(PA). MethodsFrom Jan 1995 to Dec 2004,245 patients with PA were hospitalized in our hospital.Before the operations,all the patients underwent B-ultrasonography and CT scaning,240 received intravenous pyelography and 75 MRI.The preoperative imaging diagnosis were compared with the findings during the operations and postoperative pathologic results. Results Compared with the findings during the operations,the accuracy rates of localized diagnosis for PA with B-ultrasonography,CT scanning and MRI were 92.7%,98.2% and 90.4%,respectively.Compared with the postoperative pathologic results,the accuracy rates of qualitative diagnosis for aldosterone-producing adenoma(APA) with B-ultrasonography,CT scanning and MRI were 83.0%,90.7% and 72.2%,respectively. Conclusion The comprehensive imaging data are helpful in the localized diagnosis of PA.Correct preoperative qualitative diagnosis of APA is the key step for the surgical treatment for PA.

Objective To explore the method of repairing wound defects with exposed tibia. Methods 32 patients with soft tissue defects with exposed tibia were treated with three kinds of flaps pedicled with interior,lateral and posterior vascular perforating branches in the leg,respectively.Re- suits One flap with distal part necrotic was treated with change of dressings and got one-stage healing. One case had delayed union for muscular infection under the flap.Other flaps all were successful and sur- vived.No ostemyelitis was found.Conclusion The flap pedicled with vascular perforating branches of leg has abundant blood supply and is a good method for repairing small or middle wound defect with ex- posed tibia.

OBJECTIVETo take intervention measures for health promotion after investigation of occupational health needs among employees, to analyze the economic input and output of the intervention measures, and to analyze the feasibility of health promotion through cost-effectiveness analysis and cost-benefit analysis.

METHODSA survey was conducted in an enterprise using a self-designed questionnaire to investigate the general information on enterprise, occupational history of each employee, awareness of occupational health knowledge, awareness of general health knowledge, awareness of hypertension, acquired immune deficiency syndrome, etc., lifestyle, and needs for health knowledge. Intervention measures were taken in the enterprise according to the investigation results, and then investigation and economic analysis of investment in health promotion, economic benefit, and absence of employees were performed using the questionnaire.

RESULTSAfter intervention, the awareness rate of the Code of Occupational Disease Prevention increased from 4.5% to 15.3%, the awareness rate of the definition of occupational diseases increased from 4.5% to 73.5%, and the awareness rate of the prevention and control measures for occupational diseases increased from 38.4% to 85.8%. Before intervention, 25.4%of all employees thought salt intake needed to be reduced, and this proportion increased to 92.5% after intervention. After the control strategy for health promotion, the benefit of health promotion that results from avoiding absence of employees and preventing occupational diseases was more than ten times the investment in health promotion, suggesting a significant benefit of health promotion conducted in the enterprise.

CONCLUSIONThe return on health promotion's investment for enterprise is worth. Health promotion really not just contribute to improve hygienic knowledge but increase the economic benefit.

AIMThe structure of the human penile venous system has been well studied, but disappointing outcomes of penile venous surgery in certain patients have called into question on the anatomy. We planned to extend the anatomic knowledge with the ultimate goal of improving operative success.

METHODSThirty-five patients, who had undergone penile venous surgery, complained of poor erection developed gradually 6 months to 7 years postoperatively. Cavernosography was performed again during their return visit. Seven new patients underwent spongiosography followed by immediate cavernosography. Eleven male cadavers were carefully dissected. The anatomical findings were applied to venous surgery in 155 patients, who were then followed with the International Index of Erectile Function Questionnaire-5 (IIEF-5).

RESULTSImaging observation demonstrated that the deep dorsal vein served as a common vessel of the corpora cavernosa and corpus spongiosum. A prominent cavernosal vein was found coursing along each corpus cavernosum distally to the glans, in contrast to its reported description as a short segment at the penile hilum. All cadavers had two sets of para-arterial veins sandwiching the dorsal artery. In 148 men available for follow-up, their mean IIEF-5 score was 9.3 preoperative and increased to 22.7 after the operation. The 88.5% (131/148) of the patients believed that venous stripping was a worthy treatment modality. Five cases required sildenafil to maintain their potentia, which was not working preoperatively.

CONCLUSIONSThe failure of penile venous surgery has traditionally been ascribed to penile vein regeneration. However, our finding of a long and independent cavernosal vein and an independent set of para-arterial veins may be the principal cause in patients experiencing poor postoperative results.

OBJECTIVETo search for specific serum biomarkers associated with tongue cancer by means of the serum proteomics technology.

METHODSThe tongue cancer cells of human tongue cancer cell line Tca8113 were subcutaneously inoculated into nude mice, while control nude mice were injected with phosphate-buffered saline. Serums from these two group of mice were collected for proteomic analysis using two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS).

RESULTSComparing the serum 2-DE maps from the tumor-bearing mice with those produced from control mice, we found that squamous cell carcinoma antigen 1 was over expressed only in the serum of tumor-bearing mice.

CONCLUSIONSThe squamous cell carcinoma antigen 1 may be of great potential as the biomarker of tongue cancer and as the potential therapeutic target for gene therapy.

Objective To develop a new algorithm to reconstruct the distribution of acoustic sources of magnetoacoustic tomography with magnetic induction(MAT-MI)in the acoustic inhomogeneous media,which is developed on the basis of generalized finite element method (GFEM) and modified time inversion algorithm. Methods The acoustic and acoustic coupling theory and the basic equations of acoustics were used to study the forward and inverse problems of the acoustic inhomogeneous concentric sphere magneticacoustic coupling model. The solution of acoustic non-uniform media wave equation based on GFEM was proposed.The method solved the problem of acoustically inhomogeneous media sound source reconstruction and conductivity reconstruction.At the same time,the distribution of velocity was reconstructed by rotating the pairs of transducers and the time reversal algorithm. Results The proposed algorithm could accurately reconstruct the acoustic source distribution in acoustic inhomogeneous media,and could obtain the distribution of sound velocity during the reconstruction of sound source and recover the image well. Conclusion The proposed algorithm had its feasibility and effectiveness verified,and gains advantages in MAT-MI reconstruction of acoustic inhomogeneous media.

OBJECTIVETo study the effect of nitrogen forms on nitrogen metabolism and main chemical composition of Pinellia ternate.

METHODThrough the soilless cultivation experiment and based at the same nitrogen level and different NH4(+) -N/NO3(-) -N ratios, nitrate reductase (NR) activity, glutamine synthetase (GS) activity, the content of nitrate nitrogen and ammonium nitrogen in different parts of P. ternate were determined. The contents of total alkaloid, free total organic acids and guanosine in the tuber were determined. The yield of bulbil and tuber was calculated.

RESULTThe test results showed that, with the NH4(+) -N/NO3(-) -N ratio increasing, the activity of nitrate reductase decreased, the content of nitrate nitrogen in the leaves, petioles and tuber increasing initially, then decreased, and the content of nitrate nitrogen in the root decreased. Meanwhile, with the NH4(+) -N/NO3(-) -N ratio increasing, the activity of glutamine synthetase in the leaves, petioles and root increased, the activity of glutamine synthetase in the tuber increasing initially, then decreased. The contents of ammonium nitrogen in the leaves, tuber and root increased initially, then decreased, and the contents of ammonium nitrogen in the petioles increased with the NH4(+)(-N/NO3(-)-N ratio increasing. The yield of bulbil and tuber were the highest at the NH4(+)-N/NO3(-) -N ratio of 75: 25. The content of total alkaloid and guanosine in the tuber were the highest at the NH4(+)-N/NO3(-) -N ratio of 0: 100, and the contents were 0.245% and 0.0197% respectively. With the NH4(+)-N/NO3(-) -N ratio of 50: 50, the content of free total organic acids was the highest, it reached 0.7%, however, the content of free total organic acids was the lowest at the NH4(+) -N/NO3(-) -N ratio of 0: 100.

CONCLUSIONNitrogen fertilization significant influences the nitrogen metabolism, the yield and main chemical composition of P. ternate.
