ObjectiveTo observe effects of modulated medium frequency low frequency current hydroelectric bath therapy on sequela of ankle fracture.Methods32 sequela patients of ankle fracture were treated with ZM-C type intellectual faculties intermediate frequency therapeutics instrument. Modulated medium frequency square all wave,the frequency of carry wave was 4 KHz,and the frequency of modulated wave was 100 Hz. The water temperature was 40℃. 30 minutes was a time,12 times was a course. Before and after treatment,results were contrasted themselves.ResultsAfter treatment,32 patients all got satisfactory effects,the shorter of the course,the better of the effect.ConclusionThe modulated medium frequency low frequency current hydroelectric bath therapy is a simple,safe and better effect method for sequela of ankle fracture.

Objective To explore the feasibility of low dose in MSCT thoracic angiography using Z-axis modulation. Methods The consecutive 60 patients were averagely divided into 3 groups and underwent thoracic angiography with a Toshiba Aquilion 16 scanner. The whole chest acquisition was commenced in automatic exposure control with Z-axis modulation 20-25 seconds after the contrast material was administered at the rate of 3.5-4. 0 ml/s. With the noise index (SD) as the variable, three study groups were classified as A (SD = 12) , B (SD = 15 ), and C (SD = 18 ). The mAs value per slice and the number of slices were recorded. The noises and artifacts of the axial images and the acceptability of CT angiogram were evaluated. The difference among the groups was compared by using ANOVA or nonparametric Kruskal-Wallis test. The threshold of the P value was 0. 05. Results The mean mAs value (46. 4 ± 15.6) mAs in group A was the highest but the SD value (21.6 ±7.7) was the lowest. The mean mAs value ( 37. 0 ± 13.5 ) and the SD value ( 24. 0 t 5.4 ) in group B were the mediate. The mean mAs value ( 20. 7 ±6.3) mAs in group C was the lowe(s)t but the SD value ( 30. 7 ± 6.9) was the highest ( H = 31. 390, P =0. 000). The middle slice images in all patients had the smallest mAs (40. 9,31.3,17. 1 for group A,B,C,respectively; F =9. 578, H =22. 230, F =21. 180,P =0. 000) and SD values( 16. 3, 20. 0,25.4 for group A,B,C, respectively; H = 28. 982, H = 20. 824, H = 24. 396, P = 0. 000). The acceptability of CT angiogram in all patients was excellent. The CT value of descending aorta in group A, B, and C was ( 335 ± 85 ) HU,(334 ±56)HU, and (427 ± 63 )HU, respectively. Conclusion Low dose in MSCT thoracic angiography using Z-axis modulation is feasible. We can use low dose (20 mAs, etc. ) for CT angiography when the contrast is significant.

Objective:To explore the antibacterial effect of Belamcanda Chinensis DC and Por tulaca oleracece L on P.aeruginosa (PA) in vitro.Methods:Fourty six strains PA were tested for minimum inhibition concentrati on ( MIC) by water decoct agents of the two drugs.MIC50 and MIC90 were st atistically studied.Results:For Belamcanda Chinensis DC,MIC was 31.25～3.90 g/L;MIC50 was 7 .81 g/L,and MIC90 was 15.62 g/L;whereas， for portulaca oleracece L,MIC was 31 .25～7.81 g/L, MIC50 was 15.62 g/L,and MIC90 was 31.25 g/L.Conclusion:Both of the two drugs have stronger antibacterial effects on P.ae ruginsosa in vitro.

Objective: To study the CT features and its diagnosis of spontaneous renal vein shunt (SPVA) in portal hypertension. Methods: Totally 220 cirrhosis patients with portal hypertension diagnosed clinically underwent multi-slice CT scanning. The parameters were 5 mm/6. 5 mm/2. 0 mm(collimation/effective thickness/interval) in 180 patients and 2. 5 mm/3. 2 mm/1. 6 mm in 40 patients. An arterial-phase (delaying 26-28 s) and a portal venous phase (55-60 s) were included. All images were showed by cine and CTA was displayed with volume rendering and thin-slab maximum projection when ah normal vessels were suspected. Results: The spontaneous renal shunt were found in 26 patients (11. 8%), including spleno left renal shunt(20 patients), gastro-left renal shunt (16 patients), and portal-right renal shunt(2 patients). The veins sur rounding renal hilum were rich and thick in 7 patients. Conclusion: The SPVA is not rare in portal hypertension, enhanced CT scan and angiography with multi-slice CT can effectively display the shunt vessels, contributing to the correct diagnosis and right therapy.

The Adamkiewicz artery(AKA)is the major blood supply of the spinal cord in the thoracolumbar region.The anterior two thirds of the spinal cord receive blood supply from the AKA and 75% blood supply of the spinal cord comes from the AKA.The AKA diameter is reported to be only 0.8 ～ 1.3 mm in the thoracolumbar region.In order to prevent ischemic injury to the spinal cord,the anatomy of the blood supply of the spinal cord needs to be recognized completely before invasive treatment taken in the descending thoracic and proximal abdominal aorta.Although selective angiography has been recommended,but it is time-consuming and hazardous.Multi-detector row helical CT can provide a simple protocol of scanning and relatively brief postprocessing depicting the Adamkiewicz artery with a high successful rate.Optimizing the flow velocity of contrast medium and the using of scan-triggering CT threshold are the keys of success.
