The aim of this study was to further investigate the prevalence of infection and genotype of hepatitis E virus (HEV) among different species of animals, people whose works are related to pigs and the general population in the suburb of Beijing, China. Serum and faecal samples were collected from 10 animal species and humans. Anti-HEV was detected by enzyme immunoassays (EIA); HEV RNA was amplified by reverse transcription-nested polymerase chain reaction (RT-nPCR) method. PCR products were cloned and sequenced. The isolated swine HEV sequences were analysed phylogenetically. The positive rates of serum anti-HEV in swine, cattle, milk cow, horse, sheep, donkey, dog, duck, chicken, pig farm workers and slaughterhouse workers, and general population were 81.17% (802/988), 25.29% (66/261), 14.87% (40/269), 14.29% (40/280), 9.30% (53/514), 0 (0/25), 0 (0/20), 2.53% (8/316), 3.03% (7/231), 58.73% (37/63), 35.87% (66/184) and 20.06% (538/2682), respectively. The anti-HEV prevalence in adult swine (≥6 months) and younger swine (≤3 months) was 91.49% (591/646) and 61.7% (211/342), respectively. The positive rate of HEV RNA in young swine faeces was 47.94% (93/194). All 93 isolates from the younger swine shared 87.8-100% nucleotide homology with each other and had identities of 75.6-78.9%, 73.9-76.1%, 76.4-80.6% and 83.1-95.0% with the corresponding regions of genotypes 1-4 HEV, respectively. Phylogenetic analysis showed that all HEV isolates belong to genotype 4, subgenotype 4d. These results suggest a potential risk of zoonotic transmission of HEV from younger swine to farmers who rear pigs. © 2011 Blackwell Publishing Ltd.

The development of Ewing's sarcoma (ES) is a complex process, resulting from interplay between mutations in oncogenes and tumor suppressors, host susceptibility factors, and cellular context. Cytotoxic T-lymphocyte antigen-4 (CTLA-4) plays important roles in downregulating the T-cell activation. Polymorphisms in the CTLA-4 gene have been shown to be associated with different autoimmune diseases and cancers. The current study evaluated the association of two CTLA-4 gene polymorphisms, -318C/T (rs5742909) and +49G/A (rs231775) with ES in the Chinese population. CTLA-4 polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism in 223 ES cases and 302 age-matched healthy controls. Data were analyzed using the chi-square test. Results showed that prevalence of the CTLA-4 gene +49AA genotype and +49A allele were significantly increased in ES patients compared to controls (odds ratio [OR]=2.03, 95% confidence interval [CI], 1.13-3.66, p=0.018; and OR=1.33, 95%CI, 1.03-1.72, p=0.027). Also, subjects with CA (-318, +49) haplotype had a 1.37-fold increased risk to develop ES (p=0.032). In addition, ES patients with metastasis had higher numbers of +49AA genotype than those with localized cases (OR=2.66, 95%CI, 1.14-6.22, p=0.022). These results indicate that the CTLA-4+49G/A polymorphism is a new risk factor for ES and may affect the prognosis of this cancer. © Copyright 2012, Mary Ann Liebert, Inc.

The genetic polymorphism of the CYP1A1 exon7 (rs1048943) gene is thought to have a significant effect on lung cancer risk, but the results are inconsistent. To assess this relationship more precisely, a meta-analysis was performed. Ultimately, 45 case-control studies, involving 19,689 subjects were included. A significantly increased lung cancer risk was associated with two exon7 genotype variants (for Val/Val vs Ile/Ile: odds ratio [OR] = 1.23, 95 % confidence interval [CI] = 1.10-1.43; for (Ile/Val + Val/Val) vs Ile/Ile: OR = 1.16, 95 % CI = 1.08-1.24) in the overall population. In the stratified analysis by ethnicity, gender, and smoking status, a significant association was found in Asians, Caucasians, and the female population, not the male population. Additionally, a significant association was found in the smoker population, not in the nonsmoker population. This meta-analysis suggests that the exon7 polymorphisms of CYP1A1 correlate with increased lung cancer susceptibility and there is an interaction between CYP1A1 exon7 polymorphisms and smoking, but these associations vary in different genders of the case and control populations. © 2013 International Society of Oncology and BioMarkers (ISOBM).

The transforming growth factor-beta (TGF-β) signaling pathway plays critical roles in the development of various diseases. The current study investigated whether TGF-β was involved in the pathogenesis of osteosarcoma from the genetic polymorphism perspective and serum level perspective. We first examined two TGF-β1 polymorphisms, rs1800469C/T and rs1800470T/C, in 202 osteosarcoma patients and 216 healthy controls. Data revealed that the prevalence of rs1800470TT genotype and T allele was significantly elevated in patients than in controls (odds ratio [OR]=2.28, 95% confidence interval [CI]: 1.30-3.98, p<0.001, and OR=1.49, 95% CI: 1.14-1.96, p<0.001). Function analyses showed that healthy controls carrying rs1800470TT genotype had a significantly higher serum level of TGF-β than those carrying the rs1800470CC genotype (191.1±15.7

Objective: The aim of our study was to investigate the immune status of patients with rectal cancer and its relationship with clinicopathological features. Methods: The serum levels of interleukin-8 (IL-8), tumor necrosis factor (TNF-α) and T-cell subgroup contents were measured using a double-antibody sandwich assay of ELISA in 43 patients with rectal cancer, and compared with the normal health adults. Results: In patients with rectal cancer, the serum levels of CD4, CD4/CD8 of T-cell subgroup in peripheral blood were significantly lower than the control group (P < 0.01), which gradually decreased with increase of Dukes stage; but the levels of CD8, IL-8 and TNF-α were higher than the control group, which gradually increased with increase of Dukes stage. Conclusion: The immunocompromice exists in patients with rectal cancer, there is a correlation between the contents of T-cell subgroup, IL-8 and TNF-α in serum and the Dukes stage of rectal cancer. Therefore immunotherapy can be used in patients with rectal cancer. © Huazhong University of Science and Technology and Springer-Verlag 2011.

Background: To evaluate the effect of selective double portazygous disconnection with preserving vagus (SDPDPV) for patients with portal hypertension (PHT) in the authors' hospital. Methods: Patients (453) with cirrhotic PHT who underwent either SDPDPV or pericardial devascularization with splenectomy (PDS) for variceal bleeding from February 2007 to January 2013 were retrospectively reviewed. The operation-relevant information, change of lavatory examination data, postoperative complications, and clinical outcomes were analyzed. Results: There were no significant difference between the SDPDPV group and the PDS group of mean operative time and intraoperative blood loss (P >0.05). The free portal pressure in the SDPDPV group was much lower than PDS group significantly after operation (P <0.05). The test of biochemical profile of hepatocyte functions and Child-Pugh score at the end of the first postoperative year were significantly more altered in the SDPDPV group than in the PDS group (P <0.05). Except encephalopathy, occurrences or development of postoperative complications including rebleeding, ascites, and gastric stasis showed great difference between the two groups (P <0.05). The operative mortality rate and the 3-y survival rates were great difference between the two groups too (P <0.05). Conclusions: The SDPDPV not only controls recurrent bleeding from varices with PHT effectively but also maintains normal dynamics of stomach and physiological function of intestine and hepatobiliary. © 2014 Elsevier Inc.

To perform a systematic comparative analysis of two different commercial automated systems using chemiluminescence immunoassay to quantitatively detect hepatitis B virus surface antigen (HBsAg) in patient sera. The Elecsys2010 electrical chemiluminescence immunoassay (ECLIA; manufactured by Roche) and the ARCHITECT il000 chemiluminescence magnetic microparticle immunoassay (CMIA; manufactured by Abbott) were used to detect HBsAg in 100 serum samples of individuals who presented at our department with suspected hepatitis infection between January and May 2012. The manufacturer's protocols were strictly followed. The categorical data was analyzed by Chi-squared test, and linear regression analysis was used to compare the results of the two assay systems. The HBsAg detection results from the two different assay systems showed good correlation (r >or= 0.95), and had good correlation at a low (r = 0.966), medium (r = 0.974) and high (r = 0.984) cutoff values. However, the positive detection rate of CMIA was significantly higher than that of ECLIA(94% vs. 88%, P < 0.05). When the HBsAg content was below 0.10 IU/ml, the ECLIA detection rate and sensitivity were slightly higher than those of CMIA. The ARCHITECT i1000 and Elecsys 2010 immunoassay systems have good correlation in quantitative detection of HBsAg, but the former may be more sensitive.

fast-tract surgery (FTS) has been rapidly embraced by surgeons as a mechanism for improving patient care and driving down complications and costs. The aim of this study was to determine if any improvement in outcomes occurred after FTS protocol for selective double portazygous disconnection with preserving vagus (SDPDPV) compared with non-FTS postoperative care.patients eligible for SDPDPV in the period January 2012-April 2014 were randomly selected for the FTS group or non-FTS group. A designed protocol was used in the FTS group with emphasis on an interdisciplinary approach. The non-FTS group was treated using previously established standard procedures. The number of postoperative complications, time of functional recovery and duration of hospital stay were recorded.patients in the FTS group (n=59) and non-FTS group (n=57) did not differ in terms of preoperative data and operative details (p>0.05). The FTS procedure led to significantly better control and faster restoration of gastrointestinal functions, food tolerance, rehabilitation and hospital discharge (p<0.05). Postoperative complications, including nausea/vomiting, severe ascites, wound infection, urinary tract infection and pulmonary infection were all significantly lower in the FTS group (p<0.05). According to the postoperative morbidity classification used by Clavien, overall complications and grade I complications were both significantly lower in the FTS group compared with the non-FTS group (p<0.05).adopting the FTS protocol helped to recover gastrointestinal functions, to reduce frequency of postoperative complications and to reduce hospital stay. The FTS strategy is safe and effective in improving postoperative outcomes.

To investigate the association between the dose and plasma concentration of ribavirin (RBV) and sustained virologic response (SVR) during the anti-hepatitis C virus (HCV) treatment with pegylated interferon--2b (PEG-IFN--2b) and RBV.A total of 40 patients with chronic hepatitis C (CHC) who were treated with PEG-IFN--2b and RBV as the antiviral treatment were enrolled, and according to the therapeutic effect (SVR was defined as HCV RNA maintained below the lower limit of detection at 24 weeks after drug discontinuation in patients who achieved virologic response at the end of treatment, and recurrence was defined as HCV RNA turning positive), these patients were divided into SVR group (20 patients aged 19-55 years, including 10 male patients) and recurrence group (20 patients aged 21-76 years, including 12 male patients). The HPLC-MS/MS was used to measure the RBV plasma concentration at weeks 4, 12, 24, and 48 of treatment. The t-test and receiver operating characteristic (ROC) curve were used for statistical analysis.During the antiviral treatment, the dose of RBV showed a significant difference between the two groups (15.01 1.21 mg/kg vs 10.28 2.81 mg/kg,t= 6.908,P= 0.000). The area under the ROC curve reached 0.96 (95%CI0.00-1.00,P= 0.000), suggesting that the dose of RBV had a high value in predicting SVR. When the dose of RBV was higher than 13.05 mg/kg (sensitivity 100%; specificity 85%), the possibility of achieving SVR was also increased. The RBV plasma concentrations in the SVR group at weeks 4,12, 24, and 48 of treatment were 1 894.8 740.7 ng/ml, 2 029.9 547.7 ng/ml, 2 011.8 354.2 ng/ml, and2 093.5 540.3 ng/ml, respectively, and those in the recurrence group were 1 223.1 722.7 ng/ml, 1 286.9685.4 ng/ml, 1304.7 692.0 ng/ml, and 1 221.3 655.3 ng/ml, respectively. The RBV plasma concentration at each time point showed significant differences between the two groups (t= 2.903,P= 0.006;t= 3.787,P= 0.001;t= 4.068,P= 0.000;t= 4.593,P= 0.000). The results of ROC analysis showed that the areas under the ROC curve at weeks 4, 12, 24, and 48 of treatment were 0.76 (95%CI0.61-0.92,P= 0.005), 0.83 (95%CI0.68-0.97,P= 0.000), 0.83 (95%CI0.69-0.98,P= 0.000), and 0.86 (95%CI0.72-1.00,P= 0.000), respectively, suggesting that the RBV plasma concentration had a high value in predicting SVR. When the cut-off values of RBV plasma concentration at weeks 4, 12, 24, and 48 of treatment were higher than 1262.5 ng/ml (sensitivity 90%; specificity 60%), 1432 ng/ml (sensitivity 100%; specificity 65%), 1427 ng/ml (sensitivity 100%; specificity 65%), and 1610 ng/ml (sensitivity 95%; specificity 80%), respectively, there was a greater possibility of achieving SVR.During the antiviral treatment with PEG-IFN--2b and RBV, the dose and plasma concentration of RBV have a high value in predicting the recurrence of CHC and the possibility of SVR.
