Objective To compare the therapeutic effects and side effects of cisplatin-S-1 (CS) program and docetaxel-cisplatin-S-1(DCS) program on patients with malignant gastric tumor who were treated by laparoscopic gastrectomy.MethodsA total of 67 patients in our hospital from January 2010 to June 2013 were included in this study,of which 33 cases accepted cisplatin-S-1 program (CS group),34 cases accepted DCS program (DCS group).The related side effects including diarrhea,nausea and acute upper respiratory infection,change of routine blood tests,blood biochemical index,and death caused by chemotherapy were analyzed.The related index of surgery including operation time,blood loss,recovery time of gastrointestinal function,pain incidence,hospital stay,lymph nodes resection success rate,postoperative infection,obstruction,intestinal emptying delays were recorded.Meanwhile,the 3-year survival rate after operation and postoperative 3-year recurrence rate between the two groups were compared.Results There was no significant difference in operation time,intraoperative blood loss,postoperative recovery time of gastrointestinal function,the lymph nodes resection success rate,the incidence of postoperative pain,as well as the length of hospital stay,postoperative infection rate,and complications such as obstruction and intestinal emptying delays between the two groups(P>0.05).And there was no significant difference in chemotherapy-related complications between the two groups(P>0.05).But the postoperative 3-year survival rate and postoperative 3-year recurrence rate of DCS group was better than those of the CS Group(P<0.05).Conclusion There is no significant difference in complications and surgery-related index between the two preoperative chemotherapy.However,the DCS programs have more advantages in therapeutic effects.

Objective To investigate the influence of low bilirubin level on hepatic stellate cells (HSCs) in vitro. Methods HSCs were isolated and cultured from the liver of SD rats. The effect of bilirubin in different concentration on reactive oxygen in HSCs was determined by DCFH-DA kit. The proliferation of HSCs was tested by CCK-8 test kit.Smoothmuscle α-actin (α-SMA) expression of HSCs was tested by Western blot.The apoptosis of HSCs was tested by flow cytometry.The fibrosis-related genes were tested by PCR. Results HSCs were isolated and cultured successfully.Bilirubin in low concentration (0,1,10,20 mg/L) inhibited the generation of the reactive oxygen.Proliferation and α-SMA expression of HSCs was inhibited by bilirubin (0.624 ± 0.092,0.536 ± 0.127,0.407 ± 0.033,0.399 ± 0.022,F =13.454,P ＜0.05 ; 339 ± 2,336 ± 10,246 ± 7,242 ± 5,3.7 ± 0.3,F =191.107,P ＜ 0.05 ) and the apoptosis of HSCs was promoted by bilirubin(2.69 ±0.07％,2.95 ±0.10％,4.41 ±0.22％,4.91 ±0.86％,F =34.731,P ＜0.05 ).Bilirubin in low concentration changed the expression of fibrosis-related genes in HSCs.The ratio of TIMP-1mRNA/MMP-2mRNA decreased (54 ± 2,65 ± 2,47 ± 2,44 ± 2,F =73.400,P ＜ 0.05).Conclusions Bilirubin in low concentration inhibits the proliferation and activation of hepatic stellate cells,orobablv bv a mechanism in which bilirubin promoted antioxidative function.

Objective To investigate the level of nurses′preparedness and influencing factors of nurses with low seniority in Anhui province. Methods Totally 295 nurses with low seniority were recruited by convenience sampling method. They were investigated by a self-designed demographic data questionnaire and the Disaster Preparedness Evaluation Tool. Results The score of the disaster nursing ability of the nursing managers was 163.85 ± 32.41, the mean score was 3.64 ± 0.72. Regression analysis showed that the gender, the experience of disaster rescue,disaster training were the influencing factors of disaster preparedness. Conclusions The capacity of disaster preparedness for nurses is not ideal. There is still room for improvement among nurses in Anhui province to enhance disaster preparedness, and improved disaster nursing training system is needed to achieve this.

Objective To evaluate the protective effect of hydrogen-rich saline on renal ischemia/reperfusion (I/R) in mice. Methods Thirty C57BL/6 mice were randomly divided into 3 groups: sham-operated (SO) group, I/R group (mice were injected with 5 ml/kg saline by tail vein just before ischemia induction) and hydrogen-rich saline group (mice were injected with 5 ml/kg hydrogen-rich saline). At the 6th h after reperfusion, the sera and renal samples subject to IR injury were collected. The Scr and BUN levels in serum were determined and renal histological changes were also examined. The apoptosis of renal tubular epithelial cells was measured by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay. Malondialdehyde (MDA) contents in renal samples were measured using specific kits. The infiltration of F4/80 positive macrophages and neutrophils was assayed by using immunohistochemistry. The mRNA expression of TNF-α, IL-6, IL-1β and IL-17 was detected by using real time reverse transcription PCR. Results As compared with LR group, at the 6th h following reperfusion the levels of Scr and BUN were significantly reduced (P<0.05), histological changes obviously alleviated (P<0.01), apoptosis of renal tubular epithelial cells and MDA contents was decreased (P<0.05) in hydrogen-rich saline group. Moreover, the infiltration of macrophages and neutrophils, and the mRNA expression of TNF-α, IL-6, IL-1β and IL-17 in renal tissue in hydrogen-rich saline group were also declined as compared with IR group (P<0.05). Conclusion Hydrogen-rich saline can ameliorate renal IR injury to some extent, which is associated with inhibition of inflammatory response induced by reperfusion.

To investigate the protective effects of astilbin on renal ischemia-reperfusion (IR) injury in rats.

Duck circovirus(DuCV),a potential immunosuppressive virus,was investigated in Southern China from March 2006 to December 2009 by using a polymerase chain reaction(PCR)based method. In this study,a total of 138 sick or dead duck samples from 18 different farms were examined with an average DuCV infection rate of～35%. It was found that ducks between the ages of 40～60 days were more susceptible to DuCV. There was no evidence showing that the DuCV virus was capable of vertical transmission. Farms with positive PCR results exhibited no regularly apparent clinical abnormalities such as feathering disorders,growth retardation or lower-than-average weight. The complete genomes of 9. strains from Fujian Province and 1 from Zhejiang Province were sequenced and analyzed. The 10 DuCV genomes,compared with others genomes downloaded from GenBank,ranged in size from 1988 to 1996 base pairs,with sequence identities ranging from 83.2% to 99.8%. Phylogenetic analysis based on genome sequences demonstrated that DuCVs can be divided into two distinct genetic genotypes,Group I(the Euro-USA lineage)and Group II(the Taiwan lineage),with approximately 10.0% genetic difference between the two types. Molecular epidemiological data suggest there is no obvious difference among DuCV strains isolated from different geographic locations or different species,including Duck,Muscovy duck,Mule duck,Cheery duck,Mulard duck and Pekin duck.

Objective To investigate the hypoglycemic effects of Laminaria japonica (L. japonica) on diabetic model induced by alloxan in rats. Methods Sixty healthy female rats were used to establish diabetic models by injecting alloxan peritoneally, and L.japonica was applied as raw materials for potential marine drugs.The levels of fasting blood glucose (FBG) were detected by automatic blood glucose device. Enzyme linkedimmunoabsorbant assay was applied to determine the insulin level in serum. The shape and structure of isletcells were observed with histopathological staining, and the expression of superoxide dismutase (SOD) and inducible nitric oxide synthase (iNOS) in islet cells were detected by immunohistochemical technique. Results After the treatment, the levels of FBG of L.japonica treated group B [(9.37±1.70) mmol/LandC (9.18±1.65 ) mmol/L, F= 32.81, q=6.35～11.72, P<0.05 ] reduced, while the serum levels of insulin in treated group A, Band C (0.0378±0.0026, 0.0378±0.0027, 0.0367±0.0035) increased(F= 11.40, q=4.28～8.47, P<0.05) significantly than those of diabetic model group (0.0456 ±0.0057) . The shape and structure of islet cells improved with the up-expressing SOD(t=4.73～4.76, P<0.05)and down-expressing iNOS (t=4.81～5.30, P<0.05) in L.japonica treated group B and C than those in diabetic model group. Conclusion L.japonica might decrease the serum level of FBG through promoting the islet cell recovery by an anti-oxide effect.
