Larvae of Schistosoma japonicum could be blocked in Oncomelania hupensis with pre-infection by larval Exorchis trematodes (Tang et al., 2008, 2009). The present manuscript reports the result of comparison between the two different developments of larval S.japonicum in O.hupensis snails with and without pre-infection by larval Exorchis trematodes. Of 300 (invader rate 26.74%) abnormal larvae of S.japonicum for 4-82 days old were found from 28 (73.7%) O.hupensis snails which were pre-infected with Exorchis eggs, their body structure were unusual and developed astray at early mother sporocyst stage. From 25 (69.4%) O.hupensis snails without pre- infection by larval Exorchis, 67 (invader rate 13.96%) normal mother sporocysts of S.japonicum for 5-61 days old in different development stages and many early or middle stage daughter sporocysts were found, in the 75th day after infection many mature daughter sporocysts and cercariae of S.japonicum were found. Different increase of lymphocyte in body tissues of snails were found from the two experimental O.hupensis snail groups.

[ABSTRACT]AIM:Toinvestigatetheeffectofsilencingisocitratedehydrogenase2(IDH-2)genebysmallinter-fering RNA (siRNA) on the biological characteristics of human small cell lung cancer cell line NCI -H446.METHODS:IDH-2 expression was knocked down in human small cell lung cancer cell line NCI -H446 by siRNA-IDH-2.The expression level of IDH-2 was determined by real-time PCR and Western blotting .The cell proliferation was measured by CCK-8 as-say , the protein expression of MAPK p 42 was detected by Western blotting , and the cell cycle was analyzed by flow cytome-try.The migration was observed using Transwell cell migration system .BALB/c nude mice were subcutaneously injected on the back with NCI-H446 cells transfected with siRNA-IDH-2/negative control siRNA or non-transfected cells to study the tumor growth .RESULTS:siRNA-IDH-2 remarkably down-regulated the expression of IDH-2 and MAPK p42 in the NCI-H446 cells.siRNA-IDH-2 inhibited both the proliferation and migration abilities of NCI-H446 cells, and the cell cycle was arrested in S phase as compared with negative control group .Additionally, the volume of xenograft tumors in siRNA-IDH-2 group was significantly decreased as compared with control group .CONCLUSION:siRNA-IDH-2 down-regulates the expres-sion of IDH-2 in NCI-H446 cells, reduces the cell migration efficiency and inhibits the tumor growth in vitro and in vivo.

Objective To study proteome variation between uropathogenic E. coil (UPEC)132, UPEC J96 and non-uropathogenic E. coli K-12 MG1655. Methods Two-dimensional gel electrophoresis(2-DE) was applied to compare the differential expression proteins between UPEC 132, UPEC J96 and non-uro-pathogenic E.coli K-12 MG1655. The differential expression proteins were digested in gel by enzyme. The mass of generated peptides were measured by matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS). The data obtained from peptide mass fingerprinting (PMF) were re-searched using the internet available database. Results The number of protein spots recognized from UPEC 132 was 466±11, significantly more than that of E. coli K-12 MG1655 (338±15) and UPEC J96 (382±12); there were 298 protein spots shared by the three E.coli strains, 56 protein spots shared by two UPEC strains, and 89 protein spots characterized by UPEC 132. Twenty-two differential expression or significantly increased expression protein spots, involved in virulence factors, metabolism and transportation, regulation of protein synthesis, biological oxidation and unknown functions, were successfully identified by MALDI-TOF-MS. Condusion The proteome from UPEC 132 and non-uropathogenic E. coli K-12 MG1655, or UPEC 132 and UPEC J96 was differentially expressed. It will provide important information on the pathogen-esis of UPEC 132.

Objective To investigate the effect of preoperative prophylactic parenteral nutrition on prognosis of advanced gastric cancer.Methods A total of 159 patients with advanced gastric cancer in our hospital were collected,and randomly divided into experimental group and control group.80 cases in experimental group were treated with prophylactic parenteral nutrition,and 79 cases in control group were treated with traditional nutrition.The partial indexes of liver function,complications and mortality rate were compared between the two groups before and after surgery.Results The levels of aspartate aminotransferase (AST),alanine aminotransferase (ALT),total bilirubin (TBIL) and direct bilirubin (DBIL) were much lower in experimental group than in control group at 8 days after surgery (t=6.542,6.460,5.634,5.275,all P＜0.001).The levels of ALB and PAB were much higher in experimental group than in control group at 2 and 8 days after surgery (t=12.580,12.471,6.757,12.821,all P＜0.001).The incidence of complications and mortality rate were much lower in experimental group than in control group (x2 =23.409,4.818,P＜0.001 or 0.05).Conclusions Preoperative prophylactic parenteral nutrition can speed up the recovery of liver function and reduce the complications and mortality rate after surgery in patients with advanced gastric cancer.

Febrile infection -related epilepsy syndrome(FIRES)is a newly named entity of epileptic encepha-lopathy in recent years.As one of the hot spots studied by domestic and foreign scholars,the etiology and pathogenesis of FIRES,which has a poor treatment and outcome,are undefined.It manifests with refractory seizures and status epilep-ticus in previously healthy school -aged children after banal febrile illness.In addition,with the negative response to currently available treatments,there are a poor prognosis and a high mortality rate in FIRES.Survivors are typically left with refractory partial epilepsy and severe cognitive impairment.Through domestic and foreign literature,this article re-views the potential pathogenesis,clinical features,treatment and prognosis of the syndrome,and provides theoretical ba-sis and new ideas for clinical diagnosis and treatment.

Objective To evaluate the efficacy of endovascular interventional minimally invasive techniques in treatment of acute brachial artery injury.Methods A retrospective case series study was designed to analyzed data of 16 cases (11 males and 5 females) sustaining acute brachial artery injury treated from March 2011 to August 2016.Mean age was 47.9 years (range,27-66 years).Left upper extremity vascular injury occurred in 7 cases and right upper extremity vascular injury occurred in 9.There were 13 cases of arterial intima injury and 3 of arterial pseudoaneurysm.All patients underwent endovascular therapy including stent implantation and balloon dilatation.Angiography was used to evaluate the repair of brachial artery and the operation time was recorded.Improvements of distal limb arterial pulse and limb ischemic symptoms were observed,and the patients who were followed up with stent lumen stenosis more than 50％ received endovascular treatment again.Results The procedures was successful in all patients,with operation time of 30-75 minutes (mean,45 minutes).After the insertion of a stent,recovered brachial artery blood flow and disappeared pseudoaneurysm were observed on angiography,without occurrence of stent stenosis or contrast extravasation.Symptoms of local pain and numbness were alleviated,and blood supply of the distal brachial artery was improved after operation.All patients were followed up for 3-36 months(mean,16.7 months).The false aneurysm did not recur.Two cases of stent stenosis more than 50％ had a second balloon dilation procedure and the blood flow returned to normal.Stent patency was found in 14 cases with stent stenosis of less than 50％.During the follow-up period,no ischemic necrosis,displacement of the stent or stent fracture were found.Conclusion For acute brachial artery injury,endovascular management exhibits higher technical success rate and good clinical outcome with a low incidence of complications.

Kinematical alignment during total knee arthroplasty is an emerging process, and draws more and more attentions from scholars. Knee joint is close to normal joint after TKA through kinematical alighment, which has good clinical results and functional scores, and not increase failure probility. Thus, it may increase joint stress of patella-femur joint, lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle, operative method, clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty, in order to choose a better way for kinematical alignment during total knee arthroplasty.
