Objective To study the clinical efficacy of micro-plasma radiofrequency with joint electron-beam radiation treatment for keloids.Methods A total of 15 patients with keloids over half a year were treated with single time micro-plasma radiofrequency technology by roller tip at 80-100 watts.The hypofractionated electron-beam was used,with 9 Gy dose per time covering the scar with a 1 cm margin,within 24 hours and 1 week after the micro-plasma treatment.The Vancouver Scar Scales (VSS) were assessed before and 6 months after the treatment.Patients' satisfaction and the adverse reactions were evaluated 6 months after the treatment.Results There was astatistically significant difference between the mean VSS of 15 patients pre-and 6 months posttreatment (from 11.73± 1.12 to 3.87±2.53,P＜0.05).The degree of improvement was:excellent in 1 case,good 10 cases,fair 3 cases,and poor 1 case.Patients' assessment was:extremely satisfied in 6 cases,satisfied 6 cases,approximately satisfied 2 cases and dissatisfied 1 case.The adverse reactions included hyperpigmentation within the radiation field on the anterior chest wall in 1 case and delayed healing of 1 patient 's scar wound.Conclusions Micro-plasma radiofrequency combined with electron-beam radiation therapy is highly effective and safe on keloids with good clinical application value.

Objective: To investigate mechanism on the restenosis after percutaneous transluminal coronary angioplasty (PTCA) with FSZ (Hirudo, Rhizoma Coptidis, Radix et Rhizoma Rhei, Radix Curcumae, Rhizoma Polygonati Odoroti, etc) by studying the protective effects of FSZ on arrhythmia and injury induced by ischemia and reperfusion.Methods:Rats were randomly divided into four groups and administered orally with FSZ. Left coronary artery ligature was used to form ischemia and reperfusion model. Lipid peroxidation (LPO), superoxide dismutase (SOD), cyclic adenosine monophosphate (cAMP), area of myocardial infarction, myocyte ultrastructural injury and occurrence of arrhymia were investigated.Results: FSZ could improve the changes in ST segment. In rats treated with FSZ, the levels of SOD were elevated while cAMP, LPO, and the specific viscosity of whole blood or plasma and the aggregation of the platelet were lowered, keep to improving the hemorheological changes. It also could antagonize the myocardial damage by myocardial ischemia or reperfusion reduced the area of myocardial infarction. Especially, Fufangshuizhijing Capsule reduced the area of left ventricular (LV) compared with the control group remarkably.Conclusion: FSZ could obviously antagonize arrhythmia and the injury induced by the ischemia and reperfusion, FSZ may scavenge oxygen free radical, regulate the second messenger, remarkably improve the local circulation to reduce the specific viscosity of whole blood of plasma and the aggregation of the platelet in rats, protect mitochondria safeguard the cardiac myocyte to treat PTCA.

BACKGROUNDCurrently there is a trend towards reducing radiation dose while maintaining image quality during computer tomography (CT) examination. This results from the concerns about radiation exposure from CT and the potential increase in the incidence of radiation induced carcinogenesis. This study aimed to investigate the lowest radiation dose for maintaining good image quality in adult chest scanning using GE CT equipment.

METHODSSeventy-two adult patients were examined by Gemstone Spectral CT. They were randomly divided into six groups. We set up a different value of noise index (NI) when evaluating each group every other number from 13.0 to 23.0. The original images were acquired with a slice of 5 mm thickness. For each group, several image series were reconstructed using different levels of adaptive statistical iterative reconstruction (ASIR) (30%, 50%, and 70%). We got a total of 18 image sequences of different combinations of NI and ASIR percentage. On one hand, quantitative indicators, such as CT value and standard deviation (SD), were assessed at the region of interest. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated. The volume CT dose index (CTDI) and dose length product (DLP) were recorded. On the other hand, two radiologists with ≥ 5 years of experience blindly reviewed the subjective image quality using the standards we had previously set.

RESULTSThe different combinations of noise index and ASIR were assessed. There was no significant difference in CT values among the 18 image sequences. The SD value was reduced with the noise index's reduction or ASIR's increase. There was a trend towards gradually lower SNR and CNR with an NI increase. The CTDI and DLP were diminishing as the NI increased. The scores from subjective image quality evaluation were reduced in all groups as the ASIR increased.

CONCLUSIONSIncreasing NI can reduce radiation dose. With the premise of maintaining the same image quality, using a suitable percentage of ASIR can increase the value of NI. To assure image quality, we concluded that when the NI was set at 17.0 and ASIR was 50%, the image quality could be optimal for not only satisfying the requirements of clinical diagnosis, but also achieving the purpose of low-dose scanning.
