Abstract
Studies regarding the clinical significance of quantitative hepatitis B core antibody (anti-HBc) in patients with chronic hepatitis B receiving first-line nucleos(t)ide analogues is limited. The aim of this study was to determine the performance of anti-HBc as a predictor for hepatitis B e antigen (HBeAg) seroconversion in HBeAg-positive CHB patients treated with entecavir. This was a retrospective cohort study consisting of 139 Chinese patients enrolled in a multicenter clinical trial treated with entecavir or entecavir maleate for up to 240 weeks. Anti-HBc evaluation was conducted for all the available samples using a newly developed double-sandwich anti-HBc immunoassay. At week 240, 35 (25.2%) patients achieved a serological response (HBeAg seroconversion) and these patients at week 240 had significantly higher levels of anti-HBc (P<.01). We defined 4.65 log10 IU·mL-1 , with a maximum sum of sensitivity and specificity, as the optimal cut-off value of baseline anti-HBc level to predict seroconversion. Patients with baseline anti-HBc ≥4.65 log10 IU·mL-1 had 28.0% (26/93) and 35.5% (33/93) chance of seroconversion at weeks 144 and 240, respectively. The baseline anti-HBc level was the strongest predictor for seroconversion at week 144 (OR: 5.78, 95% confidence interval [CI]: 2.05-16.34, P=.001). The baseline anti-HBc level was a strong predictor for seroconversion at week 240 (OR: 5.36, 95% CI: 2.17-13.25, P<.001). Hence, baseline anti-HBc titre is a useful predictor of long-term entecavir therapy efficacy in HBeAg-positive CHB patients, which could be used to optimize antiviral therapy.

Abstract
Esophageal squamous cell carcinoma (ESCC) is one of the major causes of cancer death worldwide, especially in Eastern Asia. Due to the poor prognosis, it is necessary to further dissect the underlying mechanisms and explore therapeutic targets of ESCC. Recently, studies show that long noncoding RNAs (lncRNAs) have critical roles in diverse biological processes, including tumorigenesis. Increasing evidence indicates that some lncRNAs are widely involved in the development and progression of ESCC, such as HOTAIR, SPRY4-IT1 and POU3F3. An emerging lncRNA, tissue differentiation-inducing nonprotein coding RNA (TINCR), has been studied in human cutaneous squamous cell carcinoma and has critical biological function, but its role in ESCC remains unknown. Here, we evaluated the expression profile of TINCR and its biological function in ESCC. In a cohort of 56 patients, TINCR was significantly overexpressed in ESCC tissues compared with paired adjacent normal tissues. Further, in vitro silencing TINCR via small interfering RNA (siRNA) inhibited the proliferation, migration and invasion of ESCC cells. Meantime, siRNA treatment induced apoptosis and blocked the progression of cell cycle. Taken together, our study suggests that TINCR promotes proliferation, migration and invasion of ESCC cells, acting as a potential oncogene of ESCC.

Abstract
Tolerance induction by means of costimulation blockade has been successfully applied in solid organ transplantation; however, its efficacy in vascularized composite allotransplantation, containing a vascularized bone marrow component and thus a constant source of donor-derived stem cells, remains poorly explored. In this study, osteomyocutaneous allografts (alloOMCs) from Balb/c (H2(d) ) mice were transplanted into C57BL/6 (H2(b) ) recipients. Immunosuppression consisted of 1 mg anti-CD154 on day 0, 0.5 mg CTLA4Ig on day 2 and rapamycin (RPM; 3 mg/kg per day from days 0-7, then every other day for 3 weeks). Long-term allograft survival, donor-specific tolerance and donor-recipient cell trafficking were evaluated. Treatment with costimulation blockade plus RPM resulted in long-term graft survival (>120 days) of alloOMC in 12 of 15 recipients compared with untreated controls (median survival time [MST] ≈10.2 ± 0.8 days), RPM alone (MST ≈33 ± 5.5 days) and costimulation blockade alone (MST ≈45.8 ± 7.1 days). Donor-specific hyporesponsiveness in recipients with viable grafts was demonstrated in vitro. Evidence of donor-specific tolerance was further assessed in vivo by secondary donor-specific skin graft survival and third-party graft rejection. A significant increase of Foxp3(+) regulatory T cells was evident in tolerant animals. Donor cells populated peripheral blood, thymus, and both donor and recipient bone marrow. Consequently, combined anti-CD154/CTLA4Ig costimulation blockade-based therapy induces donor-specific tolerance in a stringent murine alloOMC transplant model.

Abstract
AIM The aim of this paper was to explore by a quantitative method whether a 74 MBq 131I scanning activity produces a stunning effect in patients with differentiated thyroid carcinoma (DTC). METHODS We included 70 patients with DTC who had their first radioiodine treatment for ablation of thyroid remnants and/or metastases. All the patients received 1850~7400 MBq 131I. Before ablation, 34 patients (group A) performed a diagnostic scan (Dscan) 24 hours after the administration of 74 MBq 131I; 36 patients (group B) received 131I therapy without a previous Dscan. A therapeutic scan (Tscan) was performed after the ablation. The fractional concentrations of 131I in remnants or functional metastases were quantified on Dscan and Tscan, and were expressed as Dx and Tx respectively. The level of significance was set at 0.05. RESULTS For group A, 67 foci were found both on Dscan and Tscan, the mean Dx and Tx was 26.13±37.98 and 7.46±10.63 (P=0.000), respectively. For group B, 70 foci were found on Tscan, the mean Tx was 15.23±17.23, which was higher than group A significantly (P=0.002). CONCLUSION 74 MBq 131I for diagnostic scan can decrease the uptake of 131I by thyroid remnants or metastases, the thyroid stunning exists.

Abstract
Tenofovir disoproxil fumarate (TDF) has demonstrated long-term efficacy and a high barrier to resistance in multiple chronic hepatitis B (CHB) populations outside of China. This study aimed to evaluate the efficacy and safety of TDF compared with adefovir dipivoxil (ADV) in Chinese patients with CHB during 48 weeks of treatment (ClinicalTrial.gov number, NCT01300234). A Phase 3, multicentred, randomized, double-blind, controlled trial compared the efficacy and safety of TDF with ADV in Chinese patients with CHB. The primary endpoint was the proportion of patients with HBV DNA <400 copies/mL in each treatment group at Week 48, using an unpooled Z-test for superiority. Secondary endpoints included viral suppression, serologic response, histological improvement, normalization of alanine aminotransferase (ALT) levels and the emergence of resistance mutations. A total of 509 patients, 202 hepatitis B e antigen (HBeAg)-positive and 307 HBeAg-negative, with HBV DNA ≥10(5) copies/mL received either TDF 300 mg od or ADV 10 mg od. At Week 48, TDF demonstrated superior viral suppression compared with ADV in both HBeAg-positive (76.7% vs 18.2%, P < 0.0001) and HBeAg-negative (96.8% vs 71.2%, P < 0.0001) patients. The majority of patients in both treatment arms achieved ALT normalization (>85%). No resistance to TDF was observed. The frequency of adverse events was comparable between treatment arms (TDF 3.9% vs ADV 4.8%). In this double-blind, randomized, clinical trial, TDF demonstrated superiority over ADV with respect to viral suppression in Chinese patients with CHB at 48 weeks of treatment and without the development of resistance.

Abstract
Glioblastoma (GBM) is a very lethal form of human brain cancer, which is characterized by rapid diffuse, infiltrative growth and high level of cellular heterogeneity. Such cancer patients usually survive for one year under treatment. Recently, the role of small non-coding RNA known as microRNAs (miRNA), have been suggested to be involved in the pathogenesis of glioblastoma, as miRNAs play a critical role in the tumor-forming processes. The change in expression levels of several miRNAs has been found in GBM patients within last 10 years. It is evident now that impairment of miRNA regulation is one of the key mechanisms in GBM pathogenesis. The miRNA deregulation is involved in many processes, such as cell proliferation, cell cycle regulation, apoptosis, invasion, glioma stem cell behavior, and angiogenesis. GBM is also known as Grade IV astrocytoma, a rare disease with an incidence of 2-3 cases per 100,000 people in Europe and North America, and 50% with GBM die within 1 year, while 90% within 3 years. The treatments of GBM involve chemotherapy, radiation and surgery. The median survival with standard radiation and chemotherapy with Temozolomide is 1 year and 3 months, and median survival without treatment is four and a half months. In this article, symptoms of GBM, treatments, the role of miRNAs, gene expressions, types of miRNAs, neoplasms and glioblastomas, the miRNA biogenesis pathways, deregulation of miRNAs, and care of GBM have been described.

Abstract
Homologous recombination (HR) is a strategy for genetic correction. The efficiency of HR can be increased by creating a targeted double-strand break (DSB) via zinc-finger nucleases (ZFNs) and/or by introducing linear donor DNA intracellularly. Some studies have suggested that increased copy numbers of linear donor DNA may further improve HR efficiency. However, the introduction of multiple copies of a linear donor fragment remains a challenge, particularly in cell types with low transfection efficiency. In this study, we developed a vector that carries tandem repeats of a donor fragment, with each repeat flanked by ZFN target sequence fragments (TSFs). The cleavage of the flanking TSF sequence by ZFN would lead to the release of multiple linear fragment. We demonstrated that this novel vector carrying five copies of a linearizable donor fragment, when co-transfected with a ZFN-expressing vector in 293 cells, showed improved HR efficiency about 30 times, as compared with vector carry nonlinearizable donor. For the application of gene therapy, we then introduced this system into an adenoviral vector, which also revealed markedly improved ZFN-mediated HR efficiency in cells. The novel strategies presented here have the potential to promote the application of ZFNs in both basic research and disease therapy.

Abstract
BACKGROUND Renal hemorrhage is a potentially life-threatening event that may follow trauma, operation, biopsy, and sudden spontaneous rupture of renal tumors or aneurysms. Superselective renal artery embolization (SRAE) is a well-established method for such cases. OBJECTIVES To assess the effectiveness of SRAE in the treatment of renal hemorrhage at our institute. MATERIALS AND METHODS We respectively reviewed the medical records of patients who underwent SRAE for renal hemorrhage from January 2005 to June 2012. Data on patients' characteristics, indications, requirement of pre-embolization blood transfusion, angiographic finding, location of bleeding site, embolization agents, post-embolization transfusion requirement, complications and the outcome were recorded. RESULTS A total of 46 patients, aged 26-73 years, underwent SRAE because of hemorrhage after percutaneous nephrolithotomy (n = 25), partial nephrectomy (n = 6), renal biopsy (n = 2), trauma (n = 2), rupture of angiomyolipoma (n = 4), renal aneurysm (n = 1), and renal ateriovenous malformations (n = 6). A total of 41 patients (80.8 %) underwent successful embolization. Treatment failed in 5 patients with hemorrhage caused by percutaneous nephrolithotomy. Of these, four patients underwent a secondly superselective embolization and had a successful outcome. The remaining one was managed by conservative therapy with repeated blood transfusions. No patient required nephrectomy to save the life of the patient. No serious procedure-related complications occurred. CONCLUSIONS SRAE is an effective and minimal invasive method for the control of renal hemorrhage. Our experience strongly recommended the first-line use of SRAE for severe renal hemorrhage.

Abstract
We investigated a possible role of hMLH1 hypermethylation and microsatellite instability in meningioma progression. Fifty meningomas were examined for methylation of hMLH1 using a methylation-specific PCR; 43 of them were analyzed for microsatellite instability using nine microsatellite markers. Loss of heterozygosity on chromosome 22q was detected using two markers. Two atypical meningiomas showed microsatellite instability at four loci; one was methylated on hMLH1 and the other was unmethylated. Nine meningiomas were found to have methylated hMLH1; the frequencies in the different grades of meningioma were one of 20, two of 16, and six of 14, respectively. We concluded that the methylation status of hMLH1 is associated with the meningioma grade but not with microsatellite instability. Loss of heterozygosity was detected in 22 cases in at least one marker. The frequency of loss of heterozygosity increased with meningioma grade, but the tendency was not significant. The correlation between loss of heterozygosity and methylation of the hMLH1 gene was also not significant. We conclude that hypermethylation of the promoter of hMLH1 is an epigenetic change in meningiomas and is associated with the tumor grade, while microsatellite instability is an uncommon event in meningiomas.

Abstract
Epidemiological studies of the association of variants p53 Arg72Pro and MDM2 single-nucleotide polymorphism 309 (SNP309) with glioma risk have produced inconsistent results. The aim of the current study was to evaluate the association of these 2 variants with glioma susceptibility using a meta-analysis approach. For p53 Arg72Pro, 10 case-control studies including 2587 glioma patients and 4061 unrelated controls were identified. The pooled odds ratios (ORs) for Arg/Pro heterozygotes and Pro/Pro homozygotes were 1.08 [95% confidence interval (95%CI) = 0.85-1.37] and 1.08 (95%CI = 0.85-1.36), respectively, when compared to Arg/Arg carriers. Under the dominant effect model, Pro allele carriers also showed no significantly elevated glioma risk (pooled OR = 1.11, 95%CI = 0.90-1.38), and similar results were found under the recessive-effect model (pooled OR = 1.17, 95%CI = 0.85-1.61). For variant MDM2 SNP309, 3 case-control studies including 606 cases and 309 controls were identified. A marginal association with glioma risk was found for heterozygous G/T carriers (pooled OR = 1.95, 95%CI = 1.00- 3.81), whereas homozygous G/G carriers showed an increased but not significantly elevated risk of glioma (pooled OR = 2.14, 95%CI = 0.71-6.45) compared with that of T/T homozygotes. We also found no significant association between the MDM2 SNP309 polymorphism and glioma risk (pooled OR = 1.86, 95%CI = 0.94-3.67 and pooled OR = 1.25, 95%CI = 0.62-2.56, respectively) under the dominant and recessive models. Taken together, the current data suggested that the 2 polymorphisms may not contribute to glioma susceptibility.

Abstract
The optimal duration of treatment and expected response rate for hepatitis C virus genotype (HCV-6)-infected patients have not been determined. Our aims were to determine the treatment outcome with pegylated interferon (PEG-IFN) plus ribavirin for HCV-6a-infected patients at Southwest Hospital and assess the association of the on-treatment virological response with the sustained virological response (SVR). Medical records were reviewed retrospectively. Twenty-two HCV-6a-infected patients were treated for 24 weeks, and 21 (95.5%) achieved an early virological response (EVR), 20 (90.9%) an end-of-treatment response (ETR) and 18 (81.8%) a SVR. However, only 18 of the 22 HCV-6a-infected patients were tested for serum HCV RNA level at week 4 of treatment and 15 (83.3%) achieved a rapid virological response (RVR). The rates of SVR, RVR, EVR and ETR in these patients were all similar to those in HCV-2/3 treated for 24 weeks and higher than those in HCV-1b-infected patients treated for 48 weeks. A lower relapse rate (10.0%) was seen in HCV-6a compared with HCV-2/3 (12.5%) or HCV-1b-infected patients (23.3%). The positive predictive values of RVR and EVR for HCV-6a were comparable with those for HCV-2/3-infected patients (86.7%vs 90.9%, P = 0.683 and 85.7%vs 86.8%, P = 0.904, respectively). Of the 3 HCV-6a-infected patients who did not achieve a RVR, 2 achieved an EVR and went on to achieve a SVR. The patient who did not achieve an EVR did not achieve a SVR. In summary, our results indicate that 24 weeks of PEG-IFN plus ribavirin can effectively treat patients with HCV-6a chronic infection.

Abstract
OBJECTIVE Whether the oncogenic human papillomavirus (HPV) infection, especially infection with the most common subtypes 16 or 18, is related to prostate carcinogenesis remains conflicting. A meta-analysis with updated data was performed to obtain a more precise estimate of the association between them. METHODS Eligible studies were retrieved via both computer searches and review of references. The relation of HPV-16 or HPV-18 infection to prostate cancer (PC) was quantified separately. Stratified analyses based on HPV detection methods and geographic regions were also performed. Estimates of OR with 95% CI were summarized using the fixed-effect or random-effect models as appropriate. RESULTS Twenty-five eligible studies were retrieved. All the 25 studies were assigned for exploring the relation of HPV-16 infection to PC, while 13 studies provided additional information on HPV-18 simultaneously. In the overall estimates, the pooled OR indicated no significant increase of PC risk related with either HPV-16 (OR 1.09; 95% CI 0.97-1.23; P(heterogeneity) = 0.135) or HPV-18 (OR 1.05; 95% CI 0.89-1.24; P(heterogeneity) = 0.314) infection. Further quantitative assay of stratified data could also not yield any significant result, except the stratified analysis on HPV-16 DNA detection, which revealed higher HPV-16 DNA prevalence in PC cases (OR 1.54; 95% CI 1.07-2.20; P(heterogeneity) = 0.130). CONCLUSIONS Even though the overall estimates did not provide a supportive evidence for the causal role of HPV in prostate carcinogenesis, higher HPV-16 DNA prevalence in PC cases from the stratified analysis still indicated a potential association between HPV infection and PC risk in our meta-analysis.
