Synergetic effects of the combined action of carbon ions and the chemotherapy drug doxorubicin on HeLa cancer cells

Proton and carbon beam therapy is currently recognized as the most effective and highly accurate form of radiation therapy for deeply located tumors, including radioresistant ones. This is due to the fact that they have all the advantages of spatial dose distribution and, at the same time, are densely ionizing radiations capable of effectively affecting hypoxic, slow-growing tumors and other neoplasms that are insensitive to traditional types of radiation. It is well known that one of the main methods for treating neoplasms is chemotherapy. The predominant mechanism of action of anti-tumor drugs is the induction of DNA damage with the subsequent impossibility of repair. In our study, we used an anti-tumor antibiotic of the anthracycline series, doxorubicin. The assessment of the potential significance of the synergistic interaction of ionizing radiation with chemical preparations in medical radiology remains an urgent and unresolved problem. It is possible to achieve the maximum effect of the combined action of two agents when they act simultaneously. The phenomenon of synergy can be used to optimize the combined use of radiation and chemotherapy in clinical practice. In this regard, it seems relevant to conduct a study for HeLa cancer cells exposed to ionizing radiation, an antitumor drug, as well as their combination. In the course of the study, results were obtained on the manifestation of the synergistic nature of the agents used, which is of great practical and theoretical importance for understanding the mechanism of the combined effect of ionizing radiation and the chemotherapy drug (doxorubicin). The obtained data can be helpful in optimizing the combined effects in order to achieve maximum synergistic interaction.

The clinical aspects of peritonitis developing after cystectomy

Background. Surgical morbidities of radical cystectomy, which are, as a rule, complicated intraabdominal infections, appear to be the main causes of repeated surgeries and fatal outcomes. The elimination of the infection Indus and an-timicrobic therapy are the currently accepted standard of treatment for postoperative peritonitis in cancer urology, as well as in general surgery hospital.Objective: defining the most reasonable option of surgical aid for peritonitis developing after cystectomy.Materials and methods. In the time period from 2000 through 2014, 58 cancer patients with postoperative peritonitis developing after cystectomy received indoor treatment at N.N. Alexandrov Republican Research and Practical Center for Oncology and Medical Radiology. Their mean age was 64.9 years, the range 44-90 years, 53 (91.4 %) of them being male. Primary urinary bladder cancer was present in 51 (87.9 %) patients. Peritoneal infection was microbiologically verified in 57 (98.3 %) patients. Each case of fatal outcome was associated with ineffective treatment of peritonitis. Depending on the intraoperative findings (presence or absence of a hollow organ defect) and the surgical approach undertaken (obstructive resection or operation maintaining the continuity of the intestinal and/or urinary tract), the patients were stratified into three groups: group 1 (n = 28), group 2 (n = 20) and group 3 (n = 10). There were no significant differences in the basic parameters specifying peritoneal infection severity between the patients of groups 1 and 2 vs group 3 (p >0.05).Results. Overall mortality amounted to 25.9 %, 15 patients died. Among the 28 (48.3 %) patients (group 1) who underwent obstructive elimination of the peritonitis focus by means of urointestinal reservoir ablation, resection of small or large intestine with ileo- or colostomy, 6 patients died, mortality 21.4 %. In the 10 (17.2 %) patients (group 3) who succeeded in preserving the urinary conduit or continuity of the bowels by anastomosis defect closure, resection of enteroentero-anastomosis or urointestinal reservoir with repeated anastomosing or defect closure, mortality was higher (60 %) (p = 0.045); 6 patients died.Conclusion. The most effective option of surgical treatment of postoperative peritonitis developing after cystectomy is obstructive reoperation on the bowels and urinary tracts: compared with the intervention consisting in preserving the urinary conduit and/or continuity of the intestinal tract, this type of surgery caused a 2.8-fold lower mortality.

The role of IVUS and OCT in the patients with Myocardial infarction with non-obstructive coronary arteries (MINOCA)

The work presented describes what is meant by the term MINOCA and the causes that lead to the onset of this acute event, responsible for myocardial ischemic necrosis. Diagnosis with coronary angiography alone cannot be made since MINOCA is characterized in half of cases by the absence of hemodynamically significant lesions and therefore invasive coronary imaging performed through IVUS and OCT plays an important role. The two imaging techniques have peculiar characteristics that differentiate them from each other. IVUS uses ultrasound while OCT uses infrared light, but they are also distinguished in terms of spatial resolution, which is greater for OCT thus allowing better tissue characterization, and tissue penetration capacity which is greater for IVUS. In MINOCA patients, coronary artery imaging could help identify pathological changes that are not visible by coronary angiography such as plaque rupture, coronary dissection, coronary thromboembolism, coronary spasm, and coronary artery disease in patients presenting with Takotsubo syndrome. The use of intracoronary imaging (IVUS or OCT) can give us important information regarding the diagnosis and optimization of the treatment of patients with MINOCA, improving their prognosis. The medical radiology technician, within the Hemodynamics Team, must have a role of responsibility in the management of diagnostic images.

Predictors of Acute Myocardial Infarction Development in Personnel of Radiation Dangerous Plants. Medical Radiology and Radiation Safety

Purpose: To examine the predictors of acute myocardial infarction development and to evaluate the relationship of the radiation component (external γ-radiation) with the probability of developing acute myocardial infarction in workers of radiation-dangerous plants working age (under 60 for men, 55 for women), by the example of the Siberian Group of Chemical Enterprises personnel. Material and methods: The work is based on the results of a prospective population study (1998–2013). The diagnosis of acute myocardial infarction was verified in 540 people of working age (34 women and 506 men). For each case selected control (n = 1,080) among the employees of the Siberian Group of Chemical Enterprises, passed periodic medical examination in the study period. Every person was described by means of 46 variables including characteristics of social status, a number of risk factors, associated diseases, biochemical indices including the level of general cholesterol, the main clinical data, cumulative dose of external radiation and the amount of 239Pu content in an organism. Results: It was determined that in the group of the personnel of working age the most important traditional predictors of acute myocardial infarction, less important factor in the pathogenesis of the disease are conditions of the individual accumulation of a dose, but not the magnitude of the total external doses in the evaluation range. Conclusion: To improve the system of preventive measures aimed at reducing the level of morbidity and mortality from acute myocardial infarction, it is recommended to form risk groups taking into account the most significant predictors of this disease (age, systolic blood pressure, smoking). For the personnel of radiation dangerous plants working age insignificant conditions for the formation of radiation dose (age of first exposure, the rate of accumulation of radiation dose, duration of exposure) under conditions of trouble-free operation of the equipment. Active measures for the diagnosis of coronary heart disease and targeted correction of detected somatic disorders for the prevention of acute vascular catastrophes are expedient for workers of radiation hazardous industries from 40 to 60 years with an individual risk of acute myocardial infarction less than 50 % using the model described below.
