Journal of Applied Clinical Pediatrics 1986;0(02):-
The thioredoxin system consists of thioredoxin(Trx),thioredoxin reductase(TrxR)and reduced nicotinamide adenine dinucleo-tide phosphate.Trx is a small redox-active multifunctional protein.Thioredoxin 2,which is localized in the matrix mitochondria,has been shown involved in not only oxidative stress,nucleic acid metabolism,cell grow and apoptosis,but also many diseases such as organism growth and development,oxidative stress damage,cancer and ischemical reperfusion injury.It participates in redox reactions by reversible oxidation of its active center dithiol to disulfide and catalyzes dithio-disulfide exchange reactions involving many thiol-dependent processes.As signaling molecule,Trx2 participates in many signaling pathways.

OBJECTIVETo investigate clinical effect and safety of bone-setting manipulation in treating isolated systolic hypertension combined with cervical spondylosis.
METHODSFrom January 2012 to January 2015, 320 patients suffered from isolated systolic hypertension combined with cervical spondylosis were randomly divided into treatment group and control group. In treatment group, there were 160 patients including 84 males and 76 females with an average age of (39.82 ± 10.33) years old, average blood pressure was (149.61 ± 10.75)/(81.01± 8.25) mmHg, NPQ score was 24.61 ± 8.14; treated with flexion top spin and lock bone-setting manipulation of cervical spine, once every two days for 20 days. While in control group, there were 160 patients including 90 males and 70 females with an average age of(41.37 ± 9.42) years old, average blood pressure was (151.48 ± 11.32)/ (79.65 ± 9.32) mmHg, NPQ score was 25.78 ± 9.53; treated with manipulation of reposition cervical spine by rotation, once every two days for 20 days. Blood pressure and NPQ score were tested and compared for evaluating clinical effects.
RESULTSBefore and after a period treatment, systolic pressure in treatment group was (149.61 ± 10.75) mmHg and (129.67 ± 12.26) mmHg; (151.48 ± 11.32) mmHg and (132.02 ± 11.73) mmHg in control group. After treatment, systolic pressure in both two groups was obviously decreased, and treatment group was better than control group. Before and after a period treatment, diastolic pressure in treatment group was (80.01 ± 8.25) mmHg and (78.15 ± 10.34) mmHg, (79.65 ± 9.32) mmHg and (76.89 ± 9.79) mmHg in control group, and there was no significant difference between two groups. NPQ score in treatment group was 24.61 ± 8.14 before treatment, 12.46 ± 7.94 after treatment, while in control group was 25.78 ± 9.53, 14.17 ± 8.86; NPQ score of the two groups after treatment was better than before treatment, while there was no obviously significance between two groups after treatment. The whole clinical effect in treatment group was better than control group.
CONCLUSIONBone-setting manipulation for isolated systolic hypertension combined with cervical spondylosis at early stage could receive good clinical result, and flexion top spin and lock bone-setting manipulation of cervical spine was better and safety than manipulation of reposition cervical spine by rotation.

Objective To investigate the implementation and application of rotational DSA dual volume technology in displaying the intracranial artery stent.Methods Firstly,the “stent opacity”single volume technology was used to display 5 types of stent which were released in 7 cases of pure intracranial artery stenting and 12 cases of stent-assisted aneurysm embolization.Then we applied “vessel translucent”and “vessel opacity”single volume technology to display corresponding vessel segments.Finally,by coalescing the single volume imaging of stent and vessel,the “vessel opacity + stent opacity”dual volume image and “vessel translucent+ stent opacity”dual volume image were performed.We compared the effects of two kinds of dual volume imaging and assessed the imaging characteristics and influencing factors of each method.Results (1)On the “stent opacity”single volume display mode,in 7 cases of pure intracranial artery stenting,the display effect of two Pipeline stents and three Apollo stents belongs to level 1,the display effect of two Enterprise stents belongs to level 2;In 12 cases of stent-assisted aneurysm embolization,in the stent segments which weren’t influenced by artifacts,the display effect of two LEVIS stents belongs to level 1,the display effects of 5 Enterprise stents and 2 Solitaire AB stents belongs to level 2;While in the stent segments which were influenced by the artifact of spring coil and bone,the display effect significantly reduced, three pieces of Enterprise stents were even unable to identify.(2)On the “vessel opacity”single volume display mode,1 9 cases of vessel segment at the stent completed opacity display.The surface structure of vessel was very clear,but the structure under the surface was completely being covered.On the “vessel translucent”single volume display mode,the surface structure of 19 cases of vessel segment at the stent displayed clear at the tangential position.The vessel lumen also presented transparent state.(3)On the “stent opacity+vessels opacity”double volume display mode,the start-stop location and the adherence of stents in blood vessels in 1 6 cases were displayed clearly. When using the “stent opacity+ vascular opacity”double volume imaging,except 3 cases which used ball expansion Apollo stents could display comprehensive relationship between the blood vessels,in the other 13 cases,the relationship between stent and vascular could not be fully displayed.Conclusion On the condition that the single volume display technology shows stent well,the “stent opaque+vessels translucent”double volume display technology can well present the stent condition in the vessels.
