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.

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.

Objective To analyze the difference in constituent and antimicrobial resistance of pathogens in commu-nity-associated urinary tract infection(CA-UTI)and healthcare-associated UTI(HA-UTI).Methods Clinical data and microbial detection of urine specimens of 960 patients with UTI in a hospital between January 2013 and June 2014 were investigated retrospectively,difference in constituent and antimicrobial resistance of pathogens were ana-lyzed.Results 403 cases were CA-UTI,and 557 were HA-UTI;pathogens in both CA-UTI and HA-UTI were gram-negative bacteria,accounting for 78.16% and 66.97% respectively.Constituent of pathogens in CA-UTI and HA-UTI were significantly different(χ2 =21 .68,P <0.001 ).Resistant rates of Escherichia coli to piperacillin /tazobactam,cefazolin,cefoperazone / sulbactam,aztreonam,meropenem,ertapenem,gentamicin,and compound sulfamethoxazole were all significantly different between CA-UTI and HA-UTI (all P <0.05);Except aztreonam, resistant rates of Escherichia coli in HA-UTI to the other antimicrobial agents were all higher than CA-UTI.Re-sistant rates of Enterococcus faecium in HA-UTI to penicillin,ampicillin,gentamicin,levofloxacin,ciprofloxacin, and moxifloxacin were all higher than CA-UTI(all P <0.05).Conclusion Constituent and antimicrobial resistance of pathogens in CA-UTI and HA-UTI are different,proper antimicrobial agents should be chosen according to con-stituent features of pathogens and change in antimicrobial resistance,so as to prevent and reduce the emergence of drug-resistant strains,and improve therapeutic effectiveness.

Inflammatory bowel diseases (IBD) are a series of nonspecific chronic intestinal disorders,the pathogenesis is still not clear.The subtypes of IBD include Crohn's disease (CD),ulcerative colitis and inflammatory bowel disease unclassified.Previous studies showed high proportion of malnutrition and growth retardation in IBD children.So it's critical to do nutritional therapy in IBD children.Recently exclusive enteral nutrition is recognized as an effective therapy for pediatric CD to induce clinical remission and releases the parents'concerns of side effects from traditional medications.Here,the nutritional management of pediatric IBD and the role of exclusive enteral nutrition in pediatric CD were reviewed.

Objective To determine the effects of endostatin on the expression of vascular endothelial growth factor receptor?2 ( VEGFR?2 ) in non?small cell lung cancer cells ( human A549 lung adenocarcinoma cells and human Calu?1 lung carcinoma cells) , and to investigate the possible mechanisms underlying its radiosensitizing effect. Methods The CCK8 method was used to determine the inhibitory effect of endostatin on cell proliferation and calculate the drug concentration that caused a 20% reduction in cell proliferation within 24 h ( IC20 ) . RT?PCR and Western blot assays were used to assess the mRNA and protein expression of VEGFR?2, proteins within its related signaling pathways, and HIF?1α, respectively. The radiosensitivity of cells in each group was determined by colony formation assay;cell apoptosis and cell cycle distribution were determined by flow cytometry. Comparison of mean values between multiple samples was made by one?way analysis of variance, and comparison of mean values between two samples was made by t test. Results Endostatin significantly inhibited the proliferation of Calu?1 cells ( F=50?36,P<0?01) with an IC20 of 296?5 μg/ml;the mRNA and protein expression of VEGFR?2 and HIF?1α was also significantly inhibited in endostatin?treated Calu?1 cells ( F=25?43,10?44, all P<0?05) . Moreover, the phosphorylation of Akt, ERK 1/2, and p38 was significantly reduced in endostatin?treated Calu?1 cells ( F=2?89,0?24, 1?09, all P<0?05) . The radiosensitivity enhancement ratios for Calu?1 cells and A549 cells were 1?38 and 1?09, respectively. Endostatin significantly induced apoptosis ( F=44?15, P<0?01) and G2/M blockage ( F= 104?24, P< 0?01 ) in Calu?1 cells. Conclusions Endostatin induces apoptosis and enhances radiosensitivity in Calu?1 cells with high expression of VEGFR?2, but it has a limited impact on A549 cells with low expression of VEGFR?2.

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.

Objective:To investigate the effect of gold microneedle and subcutaneous apocrine excision in the treatment of bromidrosis and the occurrence of postoperative complications.Methods:From July 2019 to November 2020, 42 patients (13 males and 29 females; 16-47 years old, average 23 years old) were treated with plastic surgery in the First Affiliated Hospital of Xinjiang Medical University, 20 patients received gold microneedle treatment, and 22 patients received minimally invasive surgery (subcutaneous apocrine excision surgery). The patients were followed up for 3-6 months after operation, and the severity of preoperative bromidrosis, postoperative curative effect and occurrence of postoperative complications were compared between the two groups.Results:Eighteen cases were effective in the gold microneedle group, accounting for 90%; 22 cases were effective in the minimally invasive surgery group, accounting for 100%; the difference between the two groups was statistically significant ( P<0.05). There was a negative correlation between the grade of bromidrosis before operation and the curative effect after operation in the gold microneedle group, and the correlation coefficient was not statistically significant in the minimally invasive operation group ( P>0.05). Complications occurred in 4 cases in the gold microneedle group, accounting for 20.0%; 10 cases presented with complications in the minimally invasive surgery group, accounting for 45.5%; the difference was statistically significant ( P<0.05). Conclusions:The therapeutic effect of gold microneedle is lower than that of minimally invasive surgery, and the higher the degree of bromidrosis, the worse the curative effect. The postoperative complication rate of gold microneedle treatment for bromidrosis is lower than that of minimally invasive surgery.
