Objective To summarize the prognosis of elderly patients with colorectal cancer excision who were divided into different groups by the nutritional status before their surgery.Methods In our hospital,100 patients (age from 64 to 70)with colorectal cancer were performed the screening of nutritional risk by NRS2002 before surgery.Patients with score from 1 to 2 were as the group A,and patients with score over 3 were as group B.The related indexes and recovery between two groups were compared.Results The NRS2002 rating scale score showed that 76 patients were at nutritional risk,37 cases among them received nutrition support and had faster recovery of intestinal function the time of tube pulled out after operation[(1.8 ±0.4)d vs.(2.9 ±1.5)d],exhaust time[(2.4 ±0.6)d vs.(4.3 ±0.9)d],time of in-take food[(2.9 ±0.5)d vs.(4.5 ±1.1)d],length of stay[(10.8 ±0.9)d vs.(14.1 ±1.3)d],incidence of infection related complica-tions (0 vs.5.13%),the differences were statistically significant(P <0.05).Conclusion Problems exist in varying degrees of loss of nu-trition in elderly colorectal cancer patients before surgery,an objective assessment of the extent and targeted care and nutritional support can significantly improve the postoperative nutrition and to facilitate recovery of gastrointestinal function after surgery.

A method for simultaneous isolation and clean-up pyrethroid insecticides (methothrin, fenpropathrin,cyhalothrin, permethrin, cypermethrin, fenvalerate and deltamethrin)with a solid phase extractionmethod (Sep-Pak C18 cartridge) from biological samples (human plasma and urine) is presented.The systematic separation of the insecticides was excellently performed by wide-bore capillary gaschromatography with flame ionization detection and temperature programming. The recoveries werebetween 81% and 93% for plasma, and 90% and 102% for urine. Mixing the samples with 70%methanol and eluting with chloroform demonstrated excellent adsorption on C18 and the best recoveries,respectively.

Small cell lung cancer (SCLC) is an aggressive malignancy with fairly poor prognosis. Innovative treatment based on improved understanding of the genetic alterations of SCLC is awaited. Recently, a number of potential targets or important oncogenic pathways have been identified by the next generation sequencing or other systematic genomic analysis in SCLC. In this review, we summarised the new ifndings of genetic characteristics in SCLC.

Objective To investigate the association between serum uric acid (SUA)levels and outcome in acute ischemic stroke.Methods A total of 388 acute ischemic stroke patients were included in the prospective case study.Data on demographic characteristics, risk factors for life style, history of disease, the admission SUA and outcome at discharge were collected for all participants.Results Mean serum uric acid levels were (284.5±83.6) μmol/L in the normal uric acid? group, and(455.3±78.1)μmol/L in the high uric acid group(P＜0.01).There were significant differences in National Institutes of Health Stroke Scale (NIHSS) score at two weeks between the high UA group and the normal UA group [(11.0±6.0) vs.(11.0±5.3),P=0.048], and also in early neurological improvement (P=0.048).A significant difference was found in serum uric acid level between patients with good versus poor neurological function outcome (P =0.045).Conclusions There is the association between admission serum uric acid levels and outcome in acute ischemic stroke.Elevated serum uric acid level predicts a lower chance of a poor outcome in acute ischemic stroke.

Objective To evaluate the application value of serum endotoxin combined with integrated model for end-stage liver disease (iMELD) in evaluating the short and medium term prognosis of patients with decompensated liver cirrhosis.Methods The clinical data of 68 patients with decompensated liver cirrhosis were retrospectively analyzed.The patients were divided into survival group and death group according to the result of follow-up at the 3,6 and 12 months.The iMELD score and Child-Turcotte-Pugh (CTP) score were calculated according to relevant indicators,and the serum endotoxin level was detected.The correlation between serum endotoxin and iMELD score was analyzed in the short and medium term prognosis in patients with decompensated liver cirrhosis.Results After 3 months' follow-up,5 patients died.The iMELD scores in survival group and death group were (39.26 ± 7.29) and (49.29 ± 8.63) scores,CTP scores were (9.32 ± 2.12) and (12.03 ± 2.75) scores,serum endotoxin levels were (9.21 ± 2.24) and (15.39 ± 5.12) ng/L,and there were statistical differences (P ＜ 0.05).After 6 months'follow-up,12 patients died.The iMELD scores in survival group and death group were (41.35 ± 8.03) and (52.18 ± 10.37) scores,CTP scores were (9.78 ± 2.05) and (12.93 ± 1.99) scores,serum endotoxin levels were (8.96 ± 2.41) and (16.43 ±6.03) ng/L,and there were statistical differences (P ＜0.05).After 12 months' follow-up,19 patients died.The iMELD scores in survival group and death group were (40.74 ± 6.38) and (52.29 ± 8.53) scores,CTP scores were (10.01 ± 2.23) and (13.27 ± 1.69) scores,serum endotoxin levels were (8.53 ± 2.34) and (16.52 ± 6.08) ng/L,and there were statistical differences (P ＜ 0.05).The area under curve of receiver operating characteristic (ROC) was 0.952,standard error was 0.048,and 95％ confidence interval was 0.790-1.022.The best critical value of iMELD score to predict death was ≥48.00 scores,and the risk of death would rise if iMELD score was increased.The best critical value of serum endotoxin to predict death was ≥ 11.00 ng/L.Conclusion iMELD score and serum endotoxin have important value in predicting prognosis in patients with decompensated liver cirrhosis.

Objective To explore the mechanism of vitamin E on delaying skin aging by observ-ing the expression of hyaluronic acid synthetase-2 (HAS-2) in human dermal fibroblasts in vitro. Methods Human skin fibroblasts were cultured in vitro, and these fibroblast cells were then divided into 3 groups: different concentration of vitamin E (0, 0.1 × 10-10, 1 ×109mol/L) was added in the medium in the different group. 24 hours later, the fibroblasts were collected, RNAs extracted, and then amplified by RT-PCR. The PCR product was determined by agarose gel electrophoresis, to analyze the level of HAS-2 mRNA expression. Results RT-PCR showed the lever of HAS-2 mRNA was higher in the low-dose group than the control group, with significant difference (P<0.05) ; the lever of HAS-2 mRNA was higher in the high-dose group than control group, with significant difference (P<0.05). There was no significant difference in the lever of HAS-2 mRNA between the low-dose group and the high-dose group. Conclusions Vitamin E can enhance the expression of hyaluronic acid synthetase-2 mRNA, may increase the synthesis of HAS in skin fibroblasts and increase water content in the skin, so that it might reverse or delay the skin aging.

Attenuated Salmonella can be used not only as live vaccines but also as vectors for exogenous genes. As vectors, attenuated bacteria can deliver genes directly to tumor tissues, leading to the expression of the cloned genes and induction of specific anti-tumor immunologic responses to inhibit tumor growth. Using attenuated Salmonella as a vector offers a new approach for vaccine development.
