Objective To study the nutritional status in different age patients with esophageal cancer during radiotherapy. Methods Ninety nine patients with esophageal carcinoma accepted radiotherapy in Zhejiang Cancer Hospital from June 2012 to August 2013 were enrolled. Patients were divided into two groups by their age: the younger age<60 years; and the older age ≥60 years. Nutritional status was measured weekly during radiotherapy, and European Nutritional Risk Screening (NRS) 2002 were used to evaluate the risk of malnutrition. Results The malnutritional incidence during radiotherapy was 23.5%-29.4% and 33.8%-49.2% in the younger group and the older group, respectively. Compared with baseline nutritional parameters, triceps skinfold thickness (TSF) of the<60 years group started to differ at the first week after the start of radiotherapy (first week to the sixth week:9.14±8.67;7.80±2.90;7.62±2.83;7.56± 2.79;7.90±2.91;7.36±2.67, respectively, all P<0.01);compared with baseline nutritional parameters(2.09± 1.28), ≥60 years group started to differ at the second week (2.34 ± 1.24, P<0.05) after the start of radiotherapy for NRS2002 the third week, 2.49 ± 1.24, P=0.016;the fourth week, 2.51 ± 1.30;P=0.013, the fifth week, 2.55 ± 1.29, P=0.006; the sixth week, 2.57 ± 1.26, P=0.004. There was no significant difference between each time point for TSF in>60 years group (P>0.05). No significant difference was found for body mass index (BMI), arm circumference (AC), arm muscle circumference (AMC) in each group (P>0.05). Conclusion The elderly patients with esophageal cancer had significantly increased risk of malnutrition and decreased nutritional status than the younger patients during radiotherapy. Early start of nutrition interventions in the elderly patients may be benefitted.

Objective Ethanol, acid and alkali were used in the traditional Bererine extracting which required quite a few extracting time and polluted the environment. Water instead of ethanol was used. Microwave irradiation was chosen as the extracting method. Methods The best parameters, microwave power, extracting time, solid-liquid ratio were got in the experiment. According to the orthogonal experimental design, the optimum extracting condition was determined. Results Microwave irradiation, compared with the traditional extracting techniques, was with short extracting time. Conclusion The method was practicable and the product possessed the virtue of high purity, safe quality and free pollution.

Objective To study the effects of formaldehyde on activities of enzymes in testes of male mice. Methods Male Kunming mice were used. Experimental groups had been exposed to formaldehyde with different doses by i.p. once per day for 7 consecutive days. The formaldehyde doses were 0.2, 2.0 and 20.0 mg/kg body weight. The mice were killed after 7 days of treatment and their testes were fetched out to be made into even slurry and the activities of LDH, G-6-PD and SDH in them were tested. Results The activities of G-6-PD and SDH were decreased with the increasing of doses of formaldehyde. Compared with the control group, the activities of SDH in each exposed group had significantly decreased (P

Objective To analyze the influence of peptidimer-c on the gene expression profiling of K562 cells and investigate the mechanism of peptidimer-c inducing the apoptosis and inhibiting proliferation of K562cells.Methods Trypan blue staining technique was performed for counting the number of living K562 cells treated with peptidimer-c.The ultrastructure changes of K562 cells treated with peptidimer-c was observed under transmission electron microscope.The Human U133 Plus 3.0 gene chips were used to detect the differentially expressed genes of K562 cells treated with peptidimer-c.Reverse transcription PCR was conducted to confirm some genes identified by gene chips.Results Peptidimer-c could induce the apoptosis and inhibit the proliferation of K562 cells.Peptidimer-c caused widely changes of the gene expression profiles of K562 cells.The chip data suggested that there were 529 differentially expressed genes,of which 455 genes were up-regulated and 74 genes were down-regulated.The relevant apoptotic genes were down-regulated markedly,including JUN,AXUD1,TNFRSF10B,etc.Fifteen of the differentially expressed genes were detected by RT-PCR,which was consistent with the chip data.Conclusion Peptidimer-c may induce aooptosis of K562 cells by activating the TNF/TNFR family and the JUN family.

Objective To evaluate blood flow structure within left ventricle,quantify the variation of the flow at infarct segments,and assess the impact of myocardial infarction.Methods Twenty-eight patients with chronic myocardial infarction(CMI)and 30 healthy controls were involved.The flow vector images on the section plane of the flow within the left ventricle were acquired by vector flow mapping(VFM).Timeflow(T-F)curve and all other peak systolic and diastolic flow curve include normal velocity profile,parallel velocity profile,vector profile were analyzed by DSA-RSI program.Results Ventricular ejction peak S,rapid ventricular filling peak E and atrial systole peak A were relatively lower in CMI group at infarct segment than normal control group,the time duration from bottom to peak was relatively longer in CMI group.Normal velocity profile,parallel velocity profile,vector profile,flow profile at peak S and E were lower in CMI group than normal group.Conclusions The velocity of CMI group was lower and the time to peak was longer than that of control group.VFM is a new noninvasive and clinically useful parameter for the evaluation of regional left ventricular segment flow dynamics.

AIM:To study the effcts of caspase recruitment domain membrane-associated guanylate kinase protein 3 (CARMA3) knockdown on the growth, migration and invasion of human colonic carcinoma HCT116 cells and to analyze the mechanism.METHODS:A colonic carcinoma cell line with CARMA3 over-expression was selected.The CARMA3 gene in the HCT116 cells was knocked down by lentivirus technique.After screening by puromycin, the stably-transfected HCT116-shCARMA3 cell line was constructed.CARMA3 expression at mRNA and protein levels was detected by real-time PCR and Western blot,respectively.The cell proliferation was analyzed by WST-1 assay and RTCA S16 system.The colony formation ability was measured by colony-forming assay.The cell cycle was analyzed by flow cytometry.The cell morphological changes were observed under microscope.The abilities of migration and invasion in vitro were observed by wound healing assay and Transwell assay.The changes of related molecules were determined by Western blot to explore the mechanism.RESULTS:The expression of CARMA3 at mRNA and protein levels in the HCT116 cells was the highest in the 4 colonic carcinoma cell lines.HCT116-shCARMA3 cells with stably-silenced CARMA3 gene were successfully established.Among them, HCT116-shCARMA3-93 cells showed the greatest inhibition of CARMA3 at mRNA and protein levels.Therefore,HCT116-shCARMA3-93 cells were chosen as the cell model.Compared with control group, the morphological changes of the HCT116-shCARMA3-93 cells had epithelial-mesenchymal transition (EMT) reversion.The abilities of proliferation, colony formation, migration and invasion in the HCT116-shCARMA3-93 cells were obviously suppressed (P<0.01).G0 /G1 phase proportion was increased and S phase proportion was correspondingly decreased (P<0.05).Bcl10 and NF-κB were down-regulated, and mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT-1)showed no change.Cyclin D1 was decreased obviously and cyclin A declined slightly.Metastasis-related mar-kers matrix metalloproteinase (MMP)-2 and MMP-9 were reduced,MMP-7 remained unchanged, while tissue inhibitor of metalloproteinase(TIMP)-1 and TIMP-2 were up-regulated.Furthermore, EMT-associated molecule E-cadherin was increased, while N-cadherin, Snail, Slug and Twist were decreased to some extent.CONCLUSION:CARMA3 has an impact on the growth,migration and invasion of colonic carcinoma cell line, which is possibly related to NF-κB signaling pathway to change cell cycle and metastasis-related markers and to regulate EMT.
