Objective In order to evaluate the nutritional effect of early enteral nutrition in patients of Chinese domestic gastric cancer surgery,using evidence-based medicine methods,and supply evidence for clinical nutrition intervention.Methods CBM,Chinese academic Journals,Wanfang database and VIP Information Resource System were searched from January 2000 to March 2013 to collect the published clinical randomized controlled trials literatures of nutrition support in patients of Chinese domestic gastric cancer surgery according to inclusion and exclusion criteria of literature,using the Cochrane System Evaluation Handbook independent,double-blind principle of the literature methodology quality evaluation.Finally Meta analysis was conducted by using RevMan5.2 software.Results 14 articles were enrolled in the study,Meta analysis results showed that:early enteral nutrition comparing with parenteral nutrition in postoperative gastric cancer patients:the WMD of serum albumin was 1.55,95% CI (0.81,2.29); the WMD of serum transferrin was 0.34,95%CI (0.30,0.38);the WMD of postoperative anal exhaust time was-20.66,95%CI (-23.91,-17.40).Conclusions Early enteral nutrition is better than the parenteral nutrition,which can restore adequate serum protein source for patients,and can recover the gastrointestinal digestion and absorption function of itself earlier,which is worthy of clinical promotion.

Objective To study the diagnostic value of susceptibility weighted imaging (SWI) in diffuse axonal injury (DAI) and investigate the relationship between SWI and clinical prognosis. MethodsTwenty patients (15 males and 5 females) with DAI were included in this study. Routine sequences (T1WI, T2WI and FLAIR) and SWI were performed on a 3.0 T MRI scanner. There were 8 cases whose Glasgow score scale (GCS) ranged from 3.0 to 5.0, 4 cases from 6.0 to 8.0 and 8 from 9.0 to 12.0. The interval time between injury and examination were from 3 hours to 20 days. The number and volume of lesions observed on SWI and routine sequence were compared using Mann-Whitney U-test and paired t-test. Pearson correlation was used to analyze the relationship between the number and volume of all lesions and GCS. Results The lesions showed punctate, beaded, patchy and cord-like hypointense signal with various size on SWI (lesion diameter <2.0 cm). Distribution of lesions was multifocal with clear boundary. Routine MRI scan found a total of 78 lesions, while SWI sequence detected 424 lesions. The number of the lesions found on SWI was more than that on conventional MRI (U=-15.447,P<0.01). The total volume of the lesions measured on routine MRI and SWI were 19 340 mm3 and 38 042 mm3, respectively. The total volume measured on SWI was more than that on routine MR (t=5.870,P<0.01). The number and volume of all lesions were negatively correlated with GCS (r=-0.802, -0.767, P<0.01). Conclusion SWI sequence could find more bleeding lesions than the routine MRI sequences. The number and the volume of the lesions were closely related to GCS. SWI showed high value in the diagnosis and prediction of the prognosis of DAI.

OBJECTIVETo study the effect of compound Danshen dripping pills and atorvastatin on restenosis after abdominal aorta angioplasty in rabbits.
METHODSRabbit models of abdominal aorta restenosis after angioplasty were established and treated with saline (group A), compound Danshen dripping pills (group B), atorvastatin (group C), or compound Danshen dripping pills plus atorvastatin (group D). HE staining was used to determine the thickness of arterial intimal hyperplasia and assess the morphological changes of the narrowed artery. Immunohistochemistry was employed to detect the expression of nuclear factor-κB (NF-κB) and monocyte chemoattractant protein-1 (MCP-1).
RESULTSCompared with group A, the 3 treatment groups showed significant increased vascular cavity area and reduced intimal area and percentage of intimal hyperplasia (P<0.05). The vascular cavity area, intimal area and percentage of intimal hyperplasia levels differed significantly between group D and groups B and C (P<0.05). Immunohistochemistry showed a significant reduction of the expression rate of NF-κB and MCP-1 in the 3 treatment groups compared with group A (P<0.05), and the reduction was especially obvious in group D (P<0.05).
CONCLUTIONSCompound danshen dripping pills combined with atorvastatin produces better effects than the drugs used alone in inhibiting vascular smooth muscle cell proliferation in rabbits after abdominal aorta angioplasty possibly due to a decreased expression of MCP-1 as a result of NF-κB inhibition.

We detected Zika virus (ZIKV) in a febrile case returning from Suriname and entry China from Guangzhou Baiyun International Airport Port.Serum and saliva samples were collected from a suspected case returning from Suriname.We detected ZIKV RNA using real-time fluorescence RT-PCR methods by both in-house reagent and commercial detection kits.RT-PCR detection was carried out with saliva sample and sequence analysis was performed.Phylogenetic tree was constructed to analyze the source of imported cases.Real-time fluorescent RT-PCR result showed that saliva was detected ZIKV RNA positive while for serum was weakly positive.A specific 1 500 bp fragment in size was amplified with saliva sample by RT-PCR.Sequence analysis showed 99% homologous to the corresponding sequence of Brazil ZIKV (GenBank No.KX197250).Phylogenetic tree indicated it was located on African lineage.According to the epidemiological investigation results,clinical manifestations and nucleic acid detection of case,the suspected case was confirmed to infect Zika virus,being the first case from Suriname into Guangdong Province.

Objective To explore how leptin affects RA,especially those with joint erosion.Methods The study recruited 48 consecutive patients with RA (14 patients with knee joint effusion) and 23 age and sex matched healthy people.RA patients were grouped into low and moderate activity group [2.6<28-joint disease activity score (DAS28) ≤5.1,n =5] and high activity group (DAS28 >5.1,n =43) according DAS28-ESR;Meanwhile,they were grouped into bone erosive group (n=20) and non-erosive group (n=28) according to X-ray of both hands.Demographic data of RA patients were recorded.ELISA was applied to assess leptin and a disintegrin and metalloproteinase with thrombospondin-like motifs (ADAMTS4) in serum and synovial fluid of RA group.Sharp/van der Heijde scores were used to assess bone erosion and joint space narrowing.Leptin and ADAMTS4 from serum and synovial fluid were compared between different groups using t test,Rank sum test,Chi-square test and Analysis of Variance,and we did Pearson and Spearman's Corre-lation analyses between these values and clinical features,lab indicators and radiological scores.Moreover,we did single factor and logistic regression analyses,which facilitated screening risk factors of joint destruction.Results Serum leptin in RA group was significantly higher than that of the control group [8.06(6.24) ng/ml vs 4.62(7.13),Z=-2.113,P=0.035],and leptin was positively correlated with Shar/van der Heijde score (r=0.347,P=0.016).Serum leptin in erosive RA patients was higher than that of the non-erosive patients (Z=-2.070,P=0.038),and there was a positive correlation between leptin and ADAMTS4 only in synovial fluid of RA patients with erosion (r=0.900,P=0.037).It was found in logistic regression results that RA patients with more tender joint counts and elevated leptin were more likely to develop bone erosion [OR=1.229,95%CI (1.007,1.500),P=0.043;OR=1.159,95%CI (1.015,1.324),P=0.030].Conclusion Leptin participates RA joint destruction probably by modulating expression of ADAMTS4.Leptin and tender joint count are independent risk factors for RA with joint destruction.
