THE POSSIBILITIES OF APPLICATION OF DECIMETER-WAVE THERAPY IN DESTRUCTIVE APPENDICITIS CHILDREN

Introduction. The article presents a comparative study of the postoperative period after laparoscopic appendectomy for destructive appendicitis in children with and without application of decimetric-wave therapy (DMWT). Material and methods. The study included 299 children aged from 3 to 17 years, the average age of children accounted for 10.7 ± 3.3 years. Patients were operated on for various forms of destructive appendicitis. The patients observed included 201 boys (67.3%) and 98 girls (32.7%), Destructive appendicitis (DA) was diagnosed in 129 (43.1%) children, appendicular peritonitis (AP) - in (56.9%). Patients of the main group received DMWT, starting from the 1st day after surgery. Patients in the comparison group did not receive physiotherapy. To assess the effectiveness of the use of UHF-therapy in the postoperative period, the following groups were taken into account: 1) intestinal insufficiency syndrome (ISS) and systemic inflammatory response syndrome (SSRS); 2) postoperative complications; 3) abdominal ultrasound data; 4) the dynamics of common laboratory indices 4) the duration of the inpatient stay. Results. In DA cases without peritonitis, ISS and SSRS in the main group were observed by 15.7 and 12.8 times less than in the comparison group, with the duration of ISS decreased by 2.13 times, SSRS by 3.3 times. In AP patients the frequency of ISS decreased by 1.68 times, SSRS - by 1.97 times. By the 5th day of the postoperative period in the main group, both in DA and AP cases, there was a significant increase in the incidence of patients with both leukocytes and lymphocytes count normal for the age, LII, CRP. The inpatient stay in the main group decreased by 1.0±0.7 days in DA patients, in AP cases - by 3.3±0.7 days. Conclusion. Evaluation of the postoperative period, as well as traditional laboratory indices, confirm the effectiveness of DMWTin the postoperative period in DA cases YES, in that the local and systemic anti-inflammatory effect is more pronounced in with AP patients.

Radio imaging-spectroscopy observations of the Sun in decimetric and centimetric wavelengths

To address fundamental processes in the solar eruptive phenomena it is important to have imaging-spectroscopy over centimetric-decimetric wave range. The Chinese Spectral Radioheliograph (CSRH) in 0.4-15 GHz range with high time, space and frequency resolutions is being constructed to achieve this goal. The perspectives to open new observational windows on solar flares and CMEs will be achieved by mapping the radio emission from unstable electron populations during the basic processes of energy release. CSRH is located in a radio quiet region in Inner Mongolia of China. The array of CSRH-I in 0.4-2.0 GHz with 40 4.5m antennas has been established and starts test observations. The 60 2m antennas for array of CSRH-II in 2-15 GHz have been mounted and assembled. The progress and current status of CSRH are introduced.

Calibration and data analysis for Chinese Spectral Radioheliograph

The Chinese Spectral Radioheliograph (CSRH) is under construction in Mingantu station of NAOC in China. Now, CSRH-I which includes antenna, receiver and correlator in decimetric wave range has been established. This paper introduced calibration on CSRH and present some results of data processing.
