RESUMEN
Objective:To investigate radiation-induced somatic mutations and variations and provide theoretical basis for clarifying radiation-induced genetic changes and long-term effects by whole-genome sequencing analysis of the genetic variations of the victim of the " 5.7" 192Ir radiation accident in Nanjing. Methods:Normal back skin tissue, irradiated bone and soft tissues, and peripheral blood were collected from the victim 2 047 days post-irradiation. DNA of these samples was extracted and sequenced with high-throughput genomics and analyzed by bioinformatics method. The genetic variations of between irradiated and normal tissues were compared.Results:Compared with normal back skin tissue, there are large amounts of genetic variations in the irradiated bone and soft tissues and peripheral blood, including base substitution (transition, transversion), small insertion, small deletion, copy number variation (gain, loss) and structure variation (large deletion, large duplication, inversion, intra-chromosomal translocation, inter-chromosomal translocation). There were 10 666 genetic variations in the irradiated bone and soft tissues and 11 233 genetic variations in peripheral blood, where thousands of genes were involved in. These variations occurred in the exons, introns, UTR′3, UTR′5, splicing sites, within 5 kb upstream of transcription initiation site, within 5 kb downstream of transcription termination site, ncRNA and intergenic region. All chromosomes had genetic variations.Conclusions:There were a large number of genetic variations in the irradiated tissues and blood of the victim at 2 047 days after irradiation, which may affect the body function and cause the long-term effects.
RESUMEN
Objective:To investigate the role of concurrent chemoradiotherapy in the treatment of limited-stage small cell lung cancer (LS-SCLC) and the impact of the number of chemotherapy cycle during radiotherapy (RT) on clinical prognosis.Methods:Patients with LS-SCLC treated with definitive radiotherapy from May, 2008 to September, 2016 were included in the study. The primary endpoint was overall survival (OS), which was calculated from the start of treatment to the date of death or last follow-up. The effect of the number of concurrent chemotherapy cycle and other clinical factors on clinical efficacy was analyzed. Survival analysis was performed with Kaplan- Meier method, and multivariate analysis was performed with Cox regression model. Results:Three hundred and seventeen patients were eligible for the analysis. Among them, 129 patients received sequential chemoradiotherapy and 188 patients received concurrent chemoradiotherapy. Among patients receiving concurrent chemoradiotherapy, 86 patients received 1 cycle of concurrent chemotherapy and 102 cases of 2 cycles of concurrent chemotherapy. The median follow-up time was 22.47 months. Multivariate survival analysis showed that only clinical stage, timing of RT administration and prophylactic cranial irradiation (PCI) were the independent prognostic factor for OS. The median OS in patients who received 1 cycle and 2 cycles of concurrent chemotherapy during RT were 33.8 months and 30.4 months ( P=0.400). No matter in elder patients or in younger patients, in early RT group or in late RT group and application of PCI or not, the number of concurrent chemotherapy cycle exerted no significant impact on OS. The incidence of grade 3 or above adverse events was 20% in the 1-cycle concurrent chemotherapy group, and 13.7% in the 2-cycle concurrent chemotherapy group. Conclusions:Concurrent chemoradiotherapy is the standard treatment of LS-SCLC. Two cycles of concurrent chemotherapy during RT is not necessarily superior to 1 cycle of concurrent chemotherapy. The optimal number of concurrent chemotherapy cycle during RT need to be studied in a large prospective randomized clinical trial.
RESUMEN
Objective@#To evaluate the parabiotic tissue protection concept in the repairment of acute radiation-induced skin injury.@*Methods@#Seven patients(3 males and 4 females) with acute radiation injury treated in the Department of Plastic Surgery of the Second Affiliated Hospital of Soochow University from February 2014 to January 2018. The ages of patients ranged from 45 to 76 years. The wound areas include perineum and buttock (n=3), chest(n=2), and thigh(n=2). In the early stage, subregional " sandwich" surgical dressing was used to protect the probiotic tissue. Two months later, the necrotic tissue was clearly demarcated, the debridement was underwent, and the parabiotic tissue was preserved as far as possible. Vacuum sealing drainage(VSD)was applied to cover and soak wound with normal saline to moisturize the wound and promote the benign transformation of ecological tissue. Ten days later, the granulation grown well, and the skin flaps and myocutaneous flaps with good blood supply were designed to repair the wounds. The VSD device was continued to be used, to drain effusion under flap and promote the growth of cystic cavity granulation, with the purpose to promote blood supply of the skin flap, perform the final biological cleaning effect on the parabiotic tissue of the wound surface, promote the benign transformation of parabiotic tissue, and reduce the further necrosis.@*Results@#Seven patients with Ⅳ degree acute radiation-induced injury wounds were treated 6-10 weeks for surgery preparation, and 2-4 weeks for VSD-application after debridement. Except for part of flap was necrotized on 10th day after the first operation in one patient, all the other patients achieved satisfied outcome in a surgery. There was no further radiation-induced ulcer occurred during the 0.5-3 years of follow-up.@*Conclusions@#The concept of parabiotic tissue protection during preoperative, intraoperative and postoperative recovery phase can promote parabiotic tissue transformed to a good result after acute radiation injury, and reduce the size and depth of soft tissue necrosis, which can provide a good foundation for the secondary repair with flap and reduce complications.
RESUMEN
Objective To investigate the association between the timing of brain metastases and the prognosis of patients with small cell lung cancer (SCLC).Methods A retrospective analysis was performed in 131 patients with limited-stage SCLC firstly metastasized to the brain were admitted to our hospital from 2007 to 2015.According to the median bone metastasis-free survival (BMFS),all patients were divided into A group (BMFS ≤ 10 months,n =61) and B group (BMFS＞ 10 months,n=70).The survival rates were analyzed using the Kaplan-Meier method.Between-group comparison was performed by log-rank test.The Cox regression model was used for multivariate prognostic analysis.Results In all 131 patients,the median overall survival (OS) and 1-,2-,and 3-year OS rates were 22.5 months,87.3％,44.7％,and 20.8％,respectively.The median OS after brain metastases and 1-and 2-year OS rates were 9.3 months,39.3％ and 14.8％,respectively.No statistical significance was observed in the median OS after brain metastases between the A and B groups (8.6 vs.9.3 months,P=0.695).Moreover,the OS after brain metastases did not significantly differ in patients without PCI or those receiving different therapies after brain metastases between two groups (P=0.240-0.731).Conclusions The timing of SCLC with brain metastases is significantly correlated with the OS rather than the OS after brain metastases.Therefore,prevention of brain metastases may be an effective approach to prolong the OS of patients with SCLC.
RESUMEN
Objective@#To explore the effect of nutritional status pre-and during chemoradiotherapy on the prognosis of patients with limited- stage small cell lung cancer (LS-SCLC).@*Methods@#We retrospectively collected medical records of 172 LS-SCLC patients undergoing concurrent chemoradiotherapy in our hospital from 2000 to 2014, with 126 males and 46 females. The data of complete blood count and hepatic and renal function were collected before initial treatment, before radiotherapy, 4 weeks during radiotherapy, and 1 month after complete of treatment. The prognostic nutritional index(PNI)was calculated. Kaplan-Meier method was used to calculate the survival rate. Log-rank test was performed used to compare the survival differences between groups. Multivariate prognostic analysis was performed using Cox regression model.@*Results@#The median overall survival (OS) was 21 months, with median progression-free survival (PFS) of 11 months. At the beginning of treatment, patients with pre-treatment PNI ≥ 53 had significantly superior OS (median 37 vs 15 months, P=0.001) and PFS (median 16 vs 10 months, P=0.017). Patients with pre-treatment hemoglobin ≥140 g/L and <140 g/L had an median OS of 32 months and 17 months (P=0.019), and median PFS of 16 months and 9 months (P=0.040), respectively. During chemoradiation, patients with elevated hemoglobin had similar median OS compared with those had decreased hemoglobin (27 vs 18 months, P=0.063, but superior median PFS (15 vs 9 months, P=0.017). Multivariate analysis revealed that prophylactic cranial irradiation, pre-treatment hemoglobin ≥140 g/L, and pretreatment PNI ≥53 were independent predictors of OS and PFS in patients with LS-SCLC.@*Conclusion@#Pre-treatment nutritional status and the changes of nutritional status during chemoradiotherapy is significantly associated with the prognosis of patients with limited-stage small cell lung cancer. The patients with better pre-treatment nutritional status have a better prognosis.
RESUMEN
Objective@#To explore the treatment technique, occurrence and development patterns of such radiation injuries as in a major radiological accident in which a victim suffered mild bone marrow radiation sickness combined grade degree Ⅲ acute radiation induced skin injury, based on his dose estimation, clinical manifestations and disease treatments.@*Methods@#History inquiry in detail, earlier physical dose estimation and biological dose estimation were conducted in conjunction with analyzing the chromosome aberration of peripheral blood lymphocytes. The physical dose was estimated by Monte Carlo method.The systematic laboratory and imaging examination was performed to evaluate the condition. The comprehensive analysis was conducted to determine the diagnosis and treatment plan.@*Results@#At 3d after the exposure, "Ren" felt mild pain and discomfortable on the skin of the right index finger. The body of the right hand index finger was covered with blister at 21 d after exposure.The estimation of biological dose was 0.43 Gy (95%CI: 0.31-0.58 Gy), and the physical dose was estimated to be 36-164 Gy for each part of the right hand finger. The hematopoietic system, immune system and endocrine system were normal. The liver function index value was transiently increased. The liver damage resulted from the use of antibiotic-induced combined with the patient′s past medical history and admission examination result, and the relevant antibiotics were discontinued. The liver function returned to normal after liver protection treatment. At 22 d after irradiation, a right finger incision and decompression surgery were performed. The stem cells were extracted and implanted into the right index finger. After 59 days of hospitalization, there was no obvious discomfort in the body, and the right index finger recovered well, as well as the pain significantly relieved, and the knuckle activity was basically normal.@*Conclusions@#The patient with excessive radiation and grade Ⅲ acute radiation skin injury was successfully treated, and local application of autologous adipose-derived stem cell transplantation achieved good result .
RESUMEN
BACKGROUND@#Malignant pleural effusion (PE) was generally defined as pleural effusion containing tumors with poor prognosis. Some kinds of undefined pleural effusions due to too small amount of effusion had poor prognosis too. This study aimed to analyze the clinical characteristics and prognostic factors of patients who suffered from limited-stage small cell lung cancer (LS-SCLC) complicated with pleural effusion.@*METHODS@#A retrospective analysis included 542 patients who were diagnosed with LS-SCLC and had treatment in our hospital from October 2007 to January 2016. We had observed 109 patients who were diagnosed with pleural effusion at their first visit to the doctor. We analyzed the clinical characters, survival time and the prognostic factors of the 109 patients. Our main observation targets were overall survival (OS) and progression free survival (PFS).@*RESULTS@#The median OS and PFS of whole group were 29.4 and 18.2 months. Before treatment, survival time of patients with PE were significantly shorter than patients without PE (median OS: 21.0 vs 31.7 months; median PFS: 14.1 vs 9.1 months; Log-rank, P=0.001, P=0.014). Multi-factor analysis of multivariate Cox shows PE was the independent prognostic factor of LS-SCLC (P=0.04). Single factor analysis showed factors affecting PE patient's survival time included clinical stages, lymph node (LN) stages, KPS scores, pulmonary atelectasis and the state of pleural after treatment. Cox multi-factor analysis reminded that the state of pleural effusion after treatment was the independent prognostic factor of LS-SCLC complicated with pleural effusion (P=0.016). There were three groups was apportioned patients without pleural effusion before treatment (group 1; n=433), patients whose pleural effusion disappeared after treatment (group 2; n=67) and patients whose pleural effusion didn't disappear after treatment (group 3; n=32).The median OS were 31.7, 23.2, 16.8 months in the group 1, 2, 3 and the median PFS were 19.1, 17.9, 11.4 months. Obvious difference was noted by the comparison of survival time of these three groups (Log-rank P<0.001, P<0.002). The difference between group 2 and group 3 was significant (Log-rank P=0.046, P=0.013) while no obvious difference was noted during comparison of group 1 and group 2. For patients who have LS-SCLC complicated with PE, there is no remarkable difference between chemoradiotherapy and chemotherapy alone.@*CONCLUSIONS@#The survival time of patients who suffered from limited-stage small cell lung cancer complicated with pleural effusion was obviously shortened. The disappearing of pleural effusion after treatment was the independent favorable prognostic factor of survival. How to treat needed further investigation.

RESUMEN
Objective To investigate the effect of the timing of radiotherapy on the prognosis of limited-stage small cell lung cancer (LS-SCLC) in the elderly. Methods A retrospective analysis was performed on the clinical data of 80 elderly patients with LS-SCLC who were treated with radical sequential thoracic chemoradiotherapy from 2008 to 2014.The correlations of SER(time from the start of any treatment to the end of radiotherapy) and the number of induction chemotherapy cycles with overall survival(OS) and progression-free survival (PFS) rates was analyzed. The treatment outcomes were compared between early radiotherapy group (no later than 3 cycles of induction chemotherapy,n=37) and late radiotherapy group (after 3 cycles of induction chemotherapy,n=43).The Kaplan-Meier method was used for survival analysis. Results In all patients,the median OS and PFS were 23.5 and 13.3 months respectively. SER was significantly correlated with OS and PFS (P=0.001;P=0.001).The median OS in patients undergoing radiotherapy after 2,3,4,5,and 6 cycles of induction chemotherapy was 33.2,26.7,20.6,16.9,and 17.9 months (P=0.000),respectively. The median OS time and 1-,2-,and 5-year OS rates were 27.8 months, 87%,62%,and 34%,respectively,in the early radiotherapy group,and 17.9 months,74%,37%,and 15%, respectively,in the late radiotherapy group (P=0.017).The median PFS time and 1-,2-,and 5-year PFS rates were 17.1 months,65%,43%,and 28%,respectively,in the early radiotherapy group,and 11.9 months,49%,21%,and 14%,respectively,in the late radiotherapy group( P= 0.022). Conclusions Shorter SER achieves better treatment outcomes in elderly patients with LS-SCLC undergoing sequential chemoradiotherapy. Early radiotherapy provides a survival benefit for patients.
RESUMEN
Objective To investigate a dose response curve based on a genetic workstation with automatic analysis system of dicentric chromosome assay (DCA) for establishing a high speed dose estimation method.Methods Peripheral blood from three healthy volunteers was irradiated in vitro using 60Co γ-rays,and then lymphocytes were cultured and fixed on slides using the standard protocol for DCA.Dicentric chromosome in metaphase cells was analyzed automatically with the genetic workstation and confirmed manually,and the dose response curve of automated dicentric chromosome was fitted.Dicentric chromosome of another peripheral blood sample irradiated with different doses was manually analyzed to verify the accuracy of the above automated DCA.Results The yield of automated DCA was well fitted by an equation Y =0.018 06D2 + 0.012 79D + 0.000 489 1 with a correlation coefficient R2 =0.961.The biological dose of radiation could be accurately estimated by this dose response curve within a few minutes.Conclusions We had successfully established a new dosimetry method by analyzing dicentric chromesome automatically,which can save a lot of manual analysis time and hence has important significance for emergency rescue in nuclear accidents.
RESUMEN
Objective To investigate the late effects induced by ionizing radiation and the rehabilitation treatment of local radiation injury by medical follow-up of the patient exposed to192 Ir at 5.7 accident in Nanjing,and to provide more experience for the treatments in the medical emergency of nuclear or radiological accident.Methods According to the history inquiry and physical examination of the patient in detail and the record of clinical symptoms and signs,the changes of the blood system,immune system,reproductive system,eyes,nervous system were systematically evaluated.The effects of rehabilitation treatment for the patient with lower limb dysfunction were also assessed.Results After the medical treatments of the patient,the hematopoietic immune system was restored,but the bone marrow aspiration still showed low bone marrow hyperplasia in right ilium.Meanwhile,the level of sex hormones was within the normal range,but semen examination showed sperm motility was 0.The radiation damage also occurred in the eye lens,retina and fundus.Howevcr,the psychological evaluation showed that the patient was stable and the right lower limb skin wound healing was well except for dysfunction and pain in some extent,which was relieved after the rehabilitation treatment.Conclusions The physiological function of the exposed victim with mild bone marrow type acute radiation sickness could be completely or partially restored after the clinical treatment in the early stage.
RESUMEN
Objective To make a rapid dose estimation for a patient exposed locally to high dose radiation exposure in early stage of 5.7 192Ir source accident in Nanjing.Methods Based on source parameters,exposure pattern,and time duration,the doses were estimated using MCNP simulations with the aid of the proper East Asia adult male voxel phantom and main physiological parameters of the exposed patient.Result Absorbed doses to 16 organs or tissues were estimated to be in the range 0.03 to 9.16 Gy.Also,the iso-dose curves for the skin of legs showed clearly the dose difference between right and left legs.Absorbed doses to patient's testicles and prostrate,about 9.16 Gy,were higher than those to other organs or tissues.The skin of both legs was exposed locally to high dose radiation exposure,for which the estimated doses were in agreement with the results obtained from infrared thermal imaging.Conclusions Monte Carlo simulation technique and common software can be used for dose estimation in early stage of radiation accidents effectively with integrating proper models.
RESUMEN
Objective To make a summary of radiation-induced changes in ocular lens and retinal lesions based on dynamic follow-up of a patient exposed to a radiation exposure from 192 Ir source accident,in order to provide the information and experience for the clinical diagnosis and treatment of such injury in emergency of a nuclear or radiation accident.Methods The examination methods included eye lens and visual acuity,slit-lamp examination,fundus examination,automated perimetry,optical coherence tomography (OCT) examination,fundus photography,and fundus fluorescein angiography (FFA).The patient was followed-up for 20 months.Comparative analyses were made of the follow-up results.Results One month after 192Ir radiation exposure,the visual acuities in both eyes were 1.0.Mild age-related opacities were observed in peripheral cortex,but the fundus looked normal.Twenty months later,the patient was followed-up.The visual acuities reduced to about 0.6,evident powder-and punctuate-like opacities could be observed in the cortex of the right lens,and mild turbid foci in the posterior polar and capsule.Multiple scotomata appeared in the superior temporal and inferior nasal in the right eye.The macular fovea thickness was not changed significantly in the right eye.Examination with fundus photography demonstrated mild optical nerve atrophy,drusens,and pale optic discs,while FFA examination showed punctuate or flocculent leakages in both eyes.Conclusions The lens opacity could be induced or accelerated by radiation exposure.In addition to the posterior capsule and pole cataracts,punctuate opacity within cortical layer may also occur.It also suggests that cataract and fundus injuries may occur later during long-term follow-up,even though the eyes may look normal during early examination after the patient exposed to the radiation.
RESUMEN
Objective To use three different methods in attempt to estimate the biological dose of the patient partially exposed to 192Ir source at5.7 accident in Nanjing,so as to provide dosimetric information for clinical remedy of exposed patients in the emergency of a nuclear accident.Methods Peripheral blood samples were collected on days 5 after exposure.The biological dose was estimated by the yields of dicentrics plus rings ( dic + r),cytokinesis-block micronuclei (CBMN) assay and nucleoplasmic bridge plus FHC (NPB + FHC).The homogeneity of radiation exposure was examined by Poisson distribution of dicentrics.Results By using three different methods,the whole body equivalent dose was dic + r estimated to be 1.51 Gy (95％ CI 1.40-1.61),1.47 Gy (95％ CI 1.36-1.60) by CBMN and 1.30 Gy (95％ CI 1.00-1.60) by NPB + FHC,respectively.A non-poisson distribution was also detected,suggesting partial body radiation exposure.Conclusions The estimated whole body equivalent dose ot a non-uniform radiation exposure was consistent with clinical diagnosis,suggesting that the yields ofdic + r,CBMN,as well as NPB + FHC,are efficient approaches to the estimation of biological doses.
RESUMEN
Objective To explore the natural attenuation pattern of three biological dose estimation indexes in vivo by investigating the effect on biological dosimetry of peripheral blood sampling at different time points from the victim partially exposed to 192Ir radiation source at5.7 accident in Nanjing.Methods Peripheral blood of the patient was collected on days 5,40 and 280 after exposure,respectively.The yields of dicentrics plus rings chromosomes (dic + r),cytokinesis-block micronuclei (CBMN) and nucleoplasmic bridge + fusion + horse shoe + circular(NPB + FHC) were analyzed.The dynamic reduction and dose estimation were both observed using the biomarkers mentioned above after exposure.Results Compared to the estimates on days 5 after exposure,the dose values estimated on days 40 and 280 decreased by 34％ and 49％ fordic + r method,48％ and 79％ for the CBMN assay,and 48％ and 75％ for NPN + FHC method,respectively.Conclusions Three biological dose estimation indexes show a progressive decrease in vivo,with the half-life of dic + r/cell being 40 days.The doses estimated using these three indexes on days 40 after exposure showed a relative deviation more than 20％ compared with those on days 5 after exposure.
RESUMEN
Objective To provide nutritional supportive scheme for patients with radiation injury through the treatment of the one exposed to Nanjing 192Ir source accident.Methods The reasonable nutrition treatment scheme was made on the basis of dietary survey and nutritional index monitoring during clinical stages of the patient,including body weight,body mass index(BMI),biochemical indexes,electrolyte,etc.,as well as metabolic cart determination of resting energy expenditure (REE).Results Patient on admission (days 5 post-irradiated) weighing 42.5 kg,172 days after the first irradiated (the first skin grafting) fell to a minimum of 36 kg,then gradually rise,hen rose back to normal range on days 383 before discharge.Normal admission hemoglobin was 135 g/L,172 d after irradiated to a minimum of 54 g/L,normal discharge;when lymphocytes admission low as 0.5 × 109/L,58 days back to normal after exposure,172 days after irradiated down to 0.4 × 109/L.Serum albumin was normal admission 41.2 g/L,172 days after irradiated down to 25.3 g/L.The normal level of serum prealbumin was 0.22 g/L,248 days to a minimum of 0.04 g/L,the basic return to normal at discharge was 0.17 g/L.Admission normal liver function,bilirubin index slightly higher,the all in one parenteral nutrition after about 2.5 months later,bilirubin and liver function indicators were gradually increased,the adjusted treatment and nutrition liver and gallbladder and other gradually returned to normal after treatment.REE and the body weight were determined by metabolic cart on days 294,308 and 342 for the energy requirements.Conclusions For patient with radiation injury,appropriate nutrition therapy is a key method for the clinical treatment and rehabilitation,which can maintain the nutritional status of patients and improve clinical treatment.
RESUMEN
Objective To examine the levels of serum adipunectin (ADPN)in patients with end-stage renal disease (ESRD), and identify the relationship between serum ADPN and tumor necrosis factor (TNF)-α, high sensitivity C-reactive protein(hs-CRP) and renal function. Methods Sixty ESRD patients and twenty normal healthy persons were involved in this study. The patients were divided into three groups: patients with chronic renal failure (CRF, 18 cases), patients with hemodialysis (HD,22 cases) and patients with peritoneal dialysis (PD,20 cases). The levels of serum ADPN, TNF-α and hs-CRP were detected by means of ELISA. Differences in continuous variables be-tween the three groups were evaluated. Results The levels of serum ADPN, TNF-α and hs-CRP in CRF, HD and PD patients were signifi-cantly higher than those in control group ( P<0.01 ). Serum ADPN levels in ESRD patients were positive related to serum TNF-α( r≥0.478, P<0.01 ), and negative related to GFR ( r≥-0.582, P<0.01 ). Conclusion The level of serum ADPN was markedly in-creased in patients with ESRD, and correlated with serum TNF-α level and.renal function.
