Clin Radiol 2024; 79:e651-e658. [PMID: 38433041 DOI: 10.1016/j.crad.2024.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 01/03/2024] [Accepted: 01/09/2024] [Indexed: 03/05/2024]
Abstract
AIM To investigate the improvement in image quality of triple-low-protocol (low radiation, low contrast medium dose, low injection speed) renal artery computed tomography (CT) angiography (RACTA) using deep-learning image reconstruction (DLIR), in comparison with standard-dose single- and dual-energy CT (DECT) using adaptive statistical iterative reconstruction-Veo (ASIR-V) algorithm. MATERIALS AND METHODS Ninety patients for RACTA were divided into different groups: standard-dose single-energy CT (S group) using ASIR-V at 60% strength (60%ASIR-V), DECT (DE group) with 60%ASIR-V including virtual monochromatic images at 40 keV (DE40 group) and 70 keV (DE70 group), and the triple-low protocol single-energy CT (L group) with DLIR at high level (DLIR-H). The effective dose (ED), contrast medium dose, injection speed, standard deviation (SD), signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of abdominal aorta (AA), and left/right renal artery (LRA, RRA), and subjective scores were compared among the different groups. RESULTS The L group significantly reduced ED by 37.6% and 31.2%, contrast medium dose by 33.9% and 30.5%, and injection speed by 30% and 30%, respectively, compared to the S and DE groups. The L group had the lowest SD values for all arteries compared to the other groups (p<0.001). The SNR of RRA and LRA in the L group, and the CNR of all arteries in the DE40 group had highest value compared to others (p<0.05). The L group had the best comprehensive score with good consistency (p<0.05). CONCLUSIONS The triple-low protocol RACTA with DLIR-H significantly reduces the ED, contrast medium doses, and injection speed, while providing good comprehensive image quality.

Prediction of tumor-reactive T cell receptors from scRNA-seq data for personalized T cell therapy. Nat Biotechnol 2024:10.1038/s41587-024-02161-y. [PMID: 38454173 DOI: 10.1038/s41587-024-02161-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 02/01/2024] [Indexed: 03/09/2024]
Abstract
The identification of patient-derived, tumor-reactive T cell receptors (TCRs) as a basis for personalized transgenic T cell therapies remains a time- and cost-intensive endeavor. Current approaches to identify tumor-reactive TCRs analyze tumor mutations to predict T cell activating (neo)antigens and use these to either enrich tumor infiltrating lymphocyte (TIL) cultures or validate individual TCRs for transgenic autologous therapies. Here we combined high-throughput TCR cloning and reactivity validation to train predicTCR, a machine learning classifier that identifies individual tumor-reactive TILs in an antigen-agnostic manner based on single-TIL RNA sequencing. PredicTCR identifies tumor-reactive TCRs in TILs from diverse cancers better than previous gene set enrichment-based approaches, increasing specificity and sensitivity (geometric mean) from 0.38 to 0.74. By predicting tumor-reactive TCRs in a matter of days, TCR clonotypes can be prioritized to accelerate the manufacture of personalized T cell therapies.

The combination treatment of oncolytic adenovirus H101 with nivolumab for refractory advanced hepatocellular carcinoma: an open-label, single-arm, pilot study. ESMO Open 2024; 9:102239. [PMID: 38325225 PMCID: PMC10937204 DOI: 10.1016/j.esmoop.2024.102239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 01/05/2024] [Accepted: 01/09/2024] [Indexed: 02/09/2024] Open
Abstract
BACKGROUND H101, an innovative oncolytic adenovirus, has shown potential in modifying the tumor microenvironment from immunologically 'cold' to 'hot'. When combined with nivolumab, a programmed cell death protein 1 inhibitor, this synergy may offer substantial therapeutic benefits beyond the capabilities of each agent alone. PATIENTS AND METHODS In this pilot study, we assessed the efficacy and safety of combining H101 with nivolumab in advanced hepatocellular carcinoma (HCC) patients who failed prior systemic therapy. The participants received initial oncolytic virus (OV) pretreatment with intratumoral H101 injections (5.0 × 1011 vp/0.5 ml/vial, two vials per lesion) on days 1 and 3. Combination therapy started on day 8, with H101 administered every 2 or 4 weeks and nivolumab (240 mg) injections every 2 weeks. Treatment continued up to 12 months or until disease progression, intolerable toxicity, consent withdrawal, or study conclusion. The primary endpoint was the objective response rate (ORR). RESULTS Between March 2020 and March 2022, 18 of 21 screened patients were assessable, showing an ORR of 11.1% [two cases of partial response (PR) and five cases of stable disease], with extrahepatic injections often leading to favorable outcomes. The disease control rate stood at 38.9%, with a 6-month survival rate of 88.9%. Median progression-free survival was 2.69 months, and overall survival (OS) was 15.04 months. Common adverse events included low-grade fever (100%) and pain related to centesis (33.3%), and no grade 3/4 events were reported. Significantly, local H101 injection showed potential in reversing immune checkpoint inhibitor resistance, evidenced by over 2.5 years of extended OS in PR cases with low α-fetoprotein. Additionally, decreasing neutrophil-to-lymphocyte ratio during OV pretreatment may predict positive outcomes. CONCLUSIONS This study demonstrates the potential efficacy of combining H101 with nivolumab in treating refractory advanced HCC, with well-tolerated toxicities.

Characterization and profiling of the microRNA in small extracellular vesicles isolated from goat milk samples collected during the first week postpartum. JDS COMMUNICATIONS 2023; 4:507-512. [PMID: 38045901 PMCID: PMC10692291 DOI: 10.3168/jdsc.2022-0369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Accepted: 04/06/2023] [Indexed: 12/05/2023]
Abstract
Colostrum contains nutrients, immunoglobulins, and various bioactive compounds such as microRNA (miRNA). Less is known about the temporal changes in miRNA profiles in ruminant milk samples during the first week postpartum. In this study, we characterized and compared the profiles of miRNA in the small extracellular vesicles (sEV) isolated from colostrum (CM, collected immediately after parturition, n = 8) and transition milk (TM, collected 7 d postpartum, n = 8) from eight 1-yr-old Guanzhong dairy goats with a milk yield of approximately 500 kg/year. A total of 192 unique sEV-associated miRNA (transcripts per million >1 at least 4 samples in either CM or TM) were identified in all samples. There were 29 miRNA uniquely identified in the TM samples while no miRNA was uniquely identified in the CM samples. The abundance of the top 10 miRNA accounted for 82.4% ± 4.0% (± SD) of the total abundance, with let-7 families (e.g., let-7a/b/c-5p) being predominant in all samples. The top 10 miRNA were predicted to target 1,008 unique genes that may regulate pathways such as focal adhesion, TGF-β signaling, and axon guidance. The expression patterns of EV miRNA were similar between the 2 sample groups, although the abundance of let-7c-5p and miR-30a-3p was higher, whereas that of let-7i-5p and miR-103-3p was lower in CM than in TM. In conclusion, the core miRNAome identified in the samples from CM and TM may play an important role in cell proliferation, bone homeostasis, and neuronal network formation in newborn goat kids. The lack of differential miRNA expression between the CM and TM samples may be due to a relatively short sampling interval in which diet composition, intake and health status of ewes, and environment were relatively stable.

Abstract
PURPOSE/OBJECTIVE(S) Presently, early-onset and late-onset nasopharyngeal cancer (EONPC and LONPC, defined as age ≤ 50 years and > 50 years old, respectively) are seldom studied. The purpose of this study is to determine the clinical and survival characteristics between the NPC patients of these two age groups. MATERIALS/METHODS Patients diagnosed with NPC in The Surveillance, Epidemiology, and End Results (SEER) database from 2000 to 2018 years, and in our institution from 2014 to 2017 years were reviewed in this study. Clinicopathological characteristics, treatment modalities, and survival outcomes of EONPC and LONPC patients were analyzed and compared. RESULTS A total of 2943 patients (including 935 patients with EONPC and 2008 patients with LONPC) in the SEER database and 833 domestic patients (including 518 patients with EONPC and 315 patients with LONPC) in our center were finally enrolled. In the SEER database, both EONPC and LONPC patients displayed a greater prevalence in men. EONPC patients presented with a worse staging of regional lymph node metastasis (p < 0.001), but had a better prognosis than that in the LONPC patients (p < 0.001). More EONPC patients received chemotherapy and radiation (p < 0.001). Similar results were validated in our center, and in addition, it was found that EONPC patients had an advanced clinical stage (stage III, IVA, 92.1% vs. 85.1%, p = 0.016) and larger primary tumor volume (41.7% vs. 35.7%, p = 0.049). Meanwhile, EONPC patients had a superior overall survival (OS) (p = 0.017) and cancer-specific survival (CSS) (p = 0.004) compared to that in the LONPC patients. In univariate and multivariate Cox regression analysis, early-onset was independently associated with a higher 5-year OS (82.4% vs. 73.3%, p = 0.006). CONCLUSION EONPC patients present with more advanced lymph node metastasis stage and clinical stage, but have a better survival compared to LONPC patients. Age ≤ 50 years was an independent prognostic factor for survival outcome in NPC patients. To achieved the better individualization of the therapeutic regimen, there is the need for further studies on EONPC.

Abstract
PURPOSE/OBJECTIVE(S) Xerostomia, caused by radiation-induced parotid damage, is the most commonly reported complications of radiotherapy (RT) to nasopharyngeal carcinoma (NPC). This study aimed to evaluate the value of IVIM MR in monitoring radiation parotid gland damage and predicting the risk of xerostomia. MATERIALS/METHODS A total of 54 patients were enrolled and underwent IVIM MR scans at before RT, after the fifth fraction, halfway through the course of RT, and at the end of radiotherapy. The parameters of IVIM MR include pseudo-diffusion coefficient (D*), perfusion fraction (f), and pure diffusion coefficient (D). The degree of xerostomia in NPC patients was assessed before each MR examination using the acute radiation morbidity scoring criteria proposed by the Radiation Therapy Oncology Group (RTOG). Concurrently, the time when the patient first reported suffering from xerostomia was recorded. The IVIM parameters trend throughout the RT, and the relationships between IVIM parameters and xerostomia, were analyzed. RESULTS All of the IVIM parameters increased from pre-RT to post-RT significantly (all p < 0.001). The increase rate of D from pre-RT to halfway through the RT was 32.61%, which was significantly higher than 15.64% from halfway to post-RT (p<0.001), indicating that cell necrosis in the first half of treatment is significantly higher than that in the second half. Both D* and F had significantly increased from pre-RT to halfway through the radiotherapy (p<0.001), with an increase rate of 19.58% and 29.38%, respectively. However, no significant increase was observed from Halfway to post-RT (p>0.05), with an increase rate of 4.10% and 8.30%, respectively. This may be due to radiation-induced vasculitic dilation that is significant in the first half of the radiotherapy but plateaus in the second half. Pre-D (OR = 23.85; 95% CI = 2.39, 237.82; p = .007) and pre-D* (OR = 0.75; 95% CI = 0.63, 0.91; p = 0.003) are independent influencing factors for xerostomia at 3 months after the completion of RT. D and F were significantly higher after the fifth fraction compared with Pre-RT (both p<0.05), respectively increased 31.25% and 25.16%. D* increase by 15% (p = 0.081). IVIM scans can assess parotid gland damage early. And the average time of parotid damage underwent IVIM scan was 5.99 ± 0.84 (day), much earlier than 11.84 ± 2.74 (day) according to RTOG. CONCLUSION Our study indicates that IVIM MR can dynamically monitor radiotherapy-induced parotid gland damage, and much earlier and objectively than RTOG.

The Feasibility of Level Ib Sparing Intensity Modulated Radiation Therapy in Nasopharyngeal Carcinoma Patients with High-Risk Factors: Based on International Guideline. Int J Radiat Oncol Biol Phys 2023; 117:e606-e607.

Abstract
PURPOSE/OBJECTIVE(S) In spite of the rarity of level Ib recurrence after intensity-modulated radiation therapy, the International Guideline (IG) provides the risk factors for prophylactic coverage. In practice, however, there are significant differences between institutions. The purpose of this study is to examine the feasibility of sparing level Ib IMRT in NPC patients with high-risk factors based on IG. MATERIALS/METHODS From January 2014 to October 2017, newly-diagnostic, non-metastatic NPC patients in our center were retrospectively reviewed. According to the risk factors of prophylactic level Ib coverage in patients with negative level Ib recommended by IG, the characteristics of pre-treatment MRI were analyzed. Four high-risk factors were identified: a. involvement of the structures that drain to level Ib as first echelon (FES), including anterior half of nasal cavity, oral cavity, b. involvement of submandibular gland (SMG), c. with radiologic extranodal extension (rENE) in level II LNs, or d. maximal axial diameter (MAD)≧2 cm in level II LNs. Patients with risk factors were divided into Cohort A (with risk factors a), Cohort B (with risk factor b, but without a), and Cohort C (only with risk factors c and/or d). Recurrence rates of level Ib and regional relapse-free survival (RRFS) rates were evaluated in different cohorts. RESULTS A total of 961 patients were finally included. Thirty-six cases (3.7%) presented with radiologically positive level Ib metastasis. For the other patients with negative Ib LNs, there were 18, 65, 421, and 444 cases classified as FES involvement, SMG involvement, level II LNs with rENE, and level II nodal with MAD ≧2 cm. Excluding overlap, a total of 571 patients with risk factors were divided into three groups: Cohort A (n = 18), Cohort B (n = 49) and Cohort C (n = 504). Nine patients (9/961, 0.94%) developed level Ib recurrence. Except for 1 patient with positive Ib LNs at diagnosis, 2 did not meet any of the risk factors, while the other six (6/9, 66.7%) met at least one risk factor. The rate of recurrence at neck level Ib was highest in Cohort A (11.1%, 2/18; Ib-sparing group: 0/10, 0.0% vs Ib-covering group: 2/8, 25.0%; P = 0.183). In Cohort B, no cases were found with level Ib recurrence (0.0%, 0/49). In Cohort C, the rates were rare (0.8%, 4/504) in both groups (0.7%, 2/276 vs 0.9%, 2/228; P > 0.999). Among the three Cohorts, there were no significant differences in 5-year RRFS between two groups, which were 90.0% vs 62.5% (p = 0.248), 90.9% vs 92.0% (p = 0.905), and 92.6% vs 90.1% (p = 0.445), respectively. Among patients with high-risk factors, the incidence of grade 3-4 late dry mouth symptom was higher in the level Ib-covering group (3.1% vs 7.5%, P = 0.033). CONCLUSION Level Ib sparing appears safe and feasible for NPC patients with negative level Ib LNs, even if combined with risk factors: SMG involvement, and/or level II with rENE, and/or level II MAD ≧2 cm. Level Ib-sparing irradiation reduces dry mouth symptoms compared with level Ib-irradiation.

Abstract
Trismus is a rare complication of chemotherapy. The usefulness of a modified anterolateral thigh (ALT) flap for the repair of extensive oral defects in patients treated for chemotherapy-induced trismus was evaluated. Between 2019 and 2021, three patients with chemotherapy-induced trismus underwent scar excision. A thinned ALT flap with a central hole was designed to repair the resultant oral mucosal defects. The patients were followed up for a mean 9.3 months (range 4-18 months). The mean pre- and intraoperative maximum inter-incisal opening (MIO) was 0.7 cm (range 0-2.0 cm) and 3.6 cm (range 3.4-3.7 cm), respectively, indicating a significant operative effect. MIO at the latest follow-up was 2.4 cm (range 1.5-3.5 cm). All of the flaps survived without complications. All patients achieved a good diet and were satisfied with the aesthetics. Thorough excision of the perioral scar and restoration with a modified ALT flap achieved satisfactory mouth opening and cosmetic effects in patients with chemotherapy-induced trismus.

Abstract
OBJECTIVE There are many challenges related to the treatment of coronary atherosclerotic heart disease (CAD). Studies have confirmed that Epimedium extract inhibits myocardial injury induced by myocardial ischaemia, but the mechanism of action remains unclear. This study aimed at analysed the effective components and mechanisms of Epimedium in treating CAD based on network pharmacology and molecular docking studies and to verify the mechanism in vitro. MATERIALS AND METHODS The TCMSP and UniProt databases were used to filter for the active components and drug targets of Epimedium. The GeneCards database was used to screen disease targets associated with CAD. The intersection of the drug targets of Epimedium and the disease targets of coronary heart disease was studied to identify the targets of Epimedium in the treatment of CAD. Cytoscape software was used to establish and analyse an activity-target network. The STRING database was used to analyse a protein-protein interaction (PPI) network, and proteins in the PPI network were visualized in the R language. Bioconductor software was used for GO function and KEGG pathway enrichment analyses, and visualization analysis was performed in the R language. PyMOL software was used to verify the molecular docking between selected active components of Epimedium and the targets of CAD, and the potential key effective components of Epimedium in the treatment of coronary heart disease were identified. The involvement of the PI3K/Akt pathway was validated by Western blot analysis. RESULTS (1) Twenty-three active compounds, including Epimedium glycoside, quercetin, luteolin, and olive resin, were screened out. There were 68 common targets of Epimedium and CAD, including IL-6, ESR1, RELA, FOS, NCOA1, CCND1, EGFR, MAPK8, VEGFA, and CASP8. The potential signaling pathways involved in the treatment of CAD by Epimedium included the human cytomegalovirus infection pathway, the PI3K-Akt signaling pathway, the TNF signaling pathway, and the HIF-1 signaling pathway. (2) Luteolin, quercetin, sitosterol, and anhydroicaritin showed strong binding to targets of CAD based on molecular docking studies. (3) Epimedium extract increased the expression of PI3K, Akt and P-Akt but decreased the expression of IL-6 in vitro. CONCLUSIONS (1) Icariin, quercetin and luteolin may act on target proteins, including IL-6, ESR1, EGFR, MAPK8, VEGFA and CASP8, to participate in the regulation of the human cytomegalovirus infection pathway, the PI3K-Akt signaling pathway, the TNF signaling pathway and other signaling pathways in order to effectively treat CAD. (2) In vitro studies confirmed that Epimedium extract can treat CAD by upregulating PI3K, Akt and P-Akt protein expression and downregulating IL-6 protein expression in SD rat cardiomyocytes.

Abstract
Background The Calgary Bile Leak Rule was developed to identify patients in whom biliary stent removal via gastroscopy could be safely performed in lieu of ERCP for post-surgical bile leaks. Aims This study aimed to evaluate a Modified Calgary Bile Leak Rule (MCBLR) for a cohort of patients who underwent laparoscopic cholecystectomy complicated by bile leak. Methods This retrospective cohort study included patients who underwent ERCP for management of laparoscopic cholecystectomy-induced bile leaks between 2005 and 2017. The primary outcome was defined as the absence of persisting bile leak or other pathology on follow-up ERCP. The MCBLR includes a) normal post-surgical serum alkaline phosphatase, b) small or absent leak with no other biliary pathology on initial ERCP, and c) time between initial and follow-up ERCP was 4–8 weeks. Test performance of the prediction rule was analyzed by calculating sensitivity, specificity, positive predictive value and negative predictive value. Results 124 cases met inclusion criteria, of which 116 (94%) of bile leak cases had no leak identified during the follow-up ERCP. 8 (6.4%) had a persisting bile leak on follow-up ERCP. Bivariate analysis found no factors significantly associated with the primary outcome. The MCBLR demonstrated a sensitivity of 100% (95% CI 63% - 100%), a specificity of 35% (95% CI 26% - 44%), a positive predictive value of 10% (95% CI 4% - 18%), and a negative predictive value of 100.0% (91% to 100%). Conclusions The MCBLR demonstrated high sensitivity and negative predictive value for determining the need for repeat ERCP following endoscopic management of laparoscopic cholecystectomy-induced bile leaks.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), otherwise known as the coronavirus (COVID-19) pandemic presents one of the greatest medical challenges of our generation. Whilst commonly causing a viral pneumonitis, myocardial damage has also been suggested by elevated serum troponin values greater than the 99th centile in up to 30% of individuals who require hospitalisation and correlates with increased mortality.
Purpose
We aim to identify whether transthoracic echocardiography (TTE) parameters can elucidate the phenomenon of abnormal troponin levels. Furthermore, we seek to characterise the most frequent demographic, biochemical, echocardiographic features and co-morbidities associated with adverse outcomes in this cohort.
Methods
A retrospective analysis was conducted utilising electronic patient records of consecutive hospitalised patients with a positive COVID-19 swab between 1st March and 31st October 2020 who underwent a TTE at our institution. Pertinent variables were collected including: the clinical indication, demographics including cardiovascular (CV) risk factors, peak troponin values and fundamental echocardiographic parameters.
Results
During this 8-month period, a total of 90 patients underwent a TTE. The mean age of the cohort was 63 years of age and 56% were male. More than half (56.6%) were admitted to the intensive care unit (ICU). A salient 41.1% (n=37) of our cohort succumbed to this devastating virus. Notably, 38.9% (n=35) were of black and minority ethnic origin (BAME). A striking 64.9% (n=24) of patients who died had hypertension. The mean troponin levels were 168.7 ng/L and 176.6 ng/L (0–34 ng/L) in the survivors and non-survivors group respectively. With regards to TTE, the left ventricular parameters were similar between both groups with a mean left ventricular ejection fraction (LVEF) of 60.6% in the non-survivors. Conversely, both right ventricular (RV) dysfunction (37.8%) and raised pulmonary artery systolic pressures (PASP) (51.4%) were markedly more frequent in the patients who perished due to COVID-19 infection.
Conclusion
Remarkably, in this extremely ill group of patients who died, 91.9% of patients had a preserved LVEF. There were no overt differences between troponin levels in the survivors and non-survivors. However, hypertension, RV dysfunction and raised PASP were distinctly more prominent in the non-survivors. Thus, providing insight that a normally functioning left ventricle does not preclude to poor outcomes. Overall, this single-centre retrospective study demonstrates that the echocardiographic phenotype associated with mortality is consistent with a severe respiratory illness rather than direct myocardial injury from COVID-19. A multi-modality imaging approach may facilitate the identification of adverse tissue characterisation changes associated with this novel virus as well as guiding further risk stratification and patient management on a case-by-case basis.

Abstract
Abstract
BACKGROUND
An effective therapeutic method still hasn’t been devised for lethal high grade glioma. Thus, a method with high anti-tumoral efficiency, tumoral targeting, and acceptable side effect needs to be designed. Oncolytic virotherapy which can specifically lyse tumor cells via mass replication and deleting nucleotide metabolism related gene, like TK, required in viral replication and overexpressed in tumor cells, provides hope for patients. However, the virus only contained TK deletion is unable to show sufficient specificity of anti-tumoral response in tumor cells. Here, the adapted strain of vaccinia virus with high tumoral specificity due to TK and RR deletion and FUC1 insertion, named T601, is chosen in this project. In clinical application, intra-tumoral injection showed improved anti-tumoral efficiency and acceptable side effect. However, intra-tumoral viral injection in orthotropic glioma model is rare. In this project, various biosafety and antitumoral efficiency parameter would be tested for confirming the biosafety and reliability of intra-tumoral T601 viral injection for future clinical trials.
MATERIAL AND METHODS
For measuring the IC50 of T601, 10 different amounts of virus was tested in vitro via calculating cell viability with CCK-8(cell counting kit-8). For measuring the further antitumoral response of FCU1, different concentration of the 5-FC was added into the medium with IC50 viral amount. To ensure the biosafety of T601, MTD (maximum tolerance dose) was measured. Based on the MTD result, for evaluating the anti-tumoral efficiency, 106 pfu,105 pfu,104 pfu of virus was intra-tumoral injected in orthotopic GBM bearing mice. Tumor size was measured once a week through in vivo bioimaging system.
RESULTS
0.022 MOI, the IC50 of T601, showed high cytotoxicity of T601. Moreover, the significantly decreased cell viability under the combined treatment of 5-FC and 0.22MOI T601 showed intact anti-tumoral function. In MTD assay, except for 107 group, no significant weight loss was found. However, in 107 pfu group, mean body weight decreased around 10% and animal fatality happened on day 9. According to the MTD result, certain amount of virus was intra-tumorally injected. In all treatment group, the tumor size was significantly shrined. At the same time, the survival rate of mice under viral treatment was significantly extended.
CONCLUSION
In summary, T601 exhibited efficient anti-tumoral function and acceptable side effect. T601 treatment prolonged the survival period of GBM mice with acceptable neurotoxicity, demonstrating that T601 contains necessary criterial for intra-tumoral injection. Ultimately, this project provided basic reference information of dose for future clinical trial.

Abstract
Iodine is an essential constituent of thyroid hormone. Active iodide accumulation in the thyroid is mediated by the sodium iodide symporter (NIS), comprising the first step in thyroid hormone biosynthesis, which relies on the functional expression of NIS on the cell membrane. The retention of NIS expressed in differentiated thyroid cancer (DTC) cells allows further treatment with post-operative radioactive iodine (RAI) therapy. However, compared with normal thyroid tissue, differentiated thyroid tumors usually show a decrease in the active iodide conveyance and NIS is generally retained within the cells, indicating that posttranslational protein transfer to the plasma membrane is abnormal. In recent years, through in vitro studies and studies of patients with DTC, various methods have been tested to increase the transport rate of NIS to the cell membrane and increase the absorption of iodine. An in-depth understanding of the mechanism of NIS transport to the plasma membrane could lead to improvements in RAI therapy. Therefore, in this review, we discuss the current knowledge concerning the post-translational mechanisms that regulate NIS transport to the cell membrane and the current status of redifferentiation therapy for patients with RAI-refractory (RAIR)-DTC.

Abstract
Abstract
Background
Delayed post-polypectomy bleeding (DPPB) is a commonly described adverse event following polypectomy. Prophylactic clipping may prevent DPPB in some patient subgroups. We performed a meta-analysis to assess both the efficacy and real-world effectiveness of prophylactic clipping.
Aims
We performed a meta-analysis to assess both the efficacy and real-world effectiveness of prophylactic clipping.
Methods
We performed a database search through March 2020 for clinical trials or observational studies assessing prophylactic clipping and DPPB. Pooled risk ratios (RR) were calculated using random effects models. Subgroup, sensitivity and meta-regression analyses were performed to elucidate clinical or methodological factors associated with effects on outcomes.
Results
A total of 2,771 citations were screened, with 11 randomized controlled trials (RCTs) and 9 observational studies included, representing 24,670 colonoscopies. DPPB occurred in 2.0% of patients overall. The pooled RR of DPPB was 0.47 (95% CI 0.29 – 0.77) from RCTs enrolling only patients with polyps ≥ 20 mm. Remaining pooled RCT data did not demonstrate a benefit for clipping. The pooled RR of DPPB was 0.96 (95% CI 0.61 – 1.51) from observational studies including all polyp sizes. For patients with proximal polyps of any size, the RR was 0.73 (95% CI 0.33 - 1.62) from RCTs. Meta-regression confirmed that polyp size ≥ 20 mm significantly influenced the effect of clipping on DPPB.
Conclusions
Pooled evidence demonstrates a benefit when clipping polyps measuring ≥ 20 mm, especially in the proximal colon. In lower-risk subgroups, prophylactic clipping should not be performed.

Clinical utility of expanded non-invasive prenatal screening and chromosomal microarray analysis in high-risk pregnancy. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2021; 57:459-465.

Abstract
OBJECTIVE To evaluate the utility of expanded non-invasive prenatal screening (NIPS), compared with chromosomal microarray analysis (CMA), for the detection of chromosomal abnormalities in high-risk pregnancies. METHODS This was a multicenter retrospective study of singleton pregnancies at high risk for chromosomal abnormality. Patients who underwent expanded NIPS and CMA sequentially during pregnancy from 2015 to 2019 were included in the analysis. Pregnancies with a positive result for sex chromosome aneuploidy were excluded as the full details could not be retrieved. The utility of expanded NIPS and CMA for detection of chromosomal abnormalities in this cohort was compared by assessing the concordance between the results. RESULTS Of the 774 included high-risk pregnancies, 550 (71.1%) had a positive NIPS result, while a positive CMA result was detected in 308 (39.8%) cases. The rate of full or partial concordance between NIPS and CMA was 82.2%, 59.6% and 25.0% for trisomies 21, 18 and 13, respectively. For rare aneuploidies and segmental imbalances, NIPS and CMA results were fully or partially concordant in 7.5% and 33.3% of cases, respectively. Copy-number variants < 5 Mb were detected more often by CMA, with an incidence of 7.9% (61/774) compared with 3.1% (24/774) by NIPS. A genetic aberration was detected by CMA in 1 in 17 (5.8%) high-risk pregnancies that had a negative or non-reportable NIPS result. CONCLUSION CMA allows for comprehensive detection of genome-wide chromosomal abnormalities in high-risk pregnancies. CMA should be offered instead of expanded NIPS for high-risk pregnancies.

Abstract
Aims: We aim to provide new insights into the mechanisms of hepatocellular carcinoma (HCC) and identify key genes as biomarkers for the prognosis of HCC. Materials & methods: Differentially expressed genes between HCC tissues and normal tissues were identified via the Gene Expression Omnibus tool. The top ten hub genes screened by the degree of the protein nodes in the protein-protein interaction network also showed significant associations with overall survival in HCC patients. Results: A prognostic model containing a five-gene signature was constructed to predict the prognosis of HCC via multivariate Cox regression analysis. Conclusion: This study identified a novel five-gene signature (CDK1, CCNB1, CCNB2, BUB1 and KIF11) as a significant independent prognostic factor.

Introduction
Aortic dilatation is most commonly associated with hypertension, bicuspid aortic valve and connective tissue diseases such as Marfan’s. It is a precursor to life threatening complications such as rupture or dissection of the aorta. The current ESC Guidelines recommend surgical intervention once the aortic diameter is >50 mm in patients with Marfan syndrome (Ic) and >55 mm in patients with a bicuspid or normal aortic valve morphology (IIb). There is currently a lack of literature on the prevalence of aortic dilatation in the general or even hospital population although there is historical data suggesting the incidence of thoracic aortic aneurysm to be 5.9 cases per 100,000.
Purpose
The aim is to investigate the prevalence of aortic dilatation by echocardiography in our hospital population which may help lay the foundation for population studies and identify prognostic factors which may determine the time of surgical intervention.
Methods
We carried out a retrospective survey using the digital echocardiogram archive and the electronic patient record system at our hospital. This survey covered the period between 1st October 2016 and 1st November 2018. For randomisation purposes, all transthoracic echocardiograms (TTE) performed on every Thursday during this period were included. All patients with an echocardiographic report of aortic root or ascending aorta dilatation were enrolled. Other information including echocardiographic dimensions along with demographics and past medical history was collected.
Results
During this 24-month period, we analysed a total of 3019 TTEs. 209 patients (6.9%) were reported to have aortic dilatation. 137 (66%) were male and the median age was 67 years. The mean height and weight were 169cm and 80kg, respectively. A bicuspid aortic valve was confirmed in 10 (4.8%) patients. 132 (63%) patients had a history of hypertension. On echocardiogram, 75 (36%) patients had septal hypertrophy and 26 (12.4%) had a dilated left ventricle.
Conclusion
Our findings are unique and for the first time, to our knowledge, we report the echocardiographic prevalence of aortic dilatation in the hospital population (6.9%). It is a staggering 40-fold increase when compared to the the prevalence of aortic aneurysm, the most likely end point of aortic dilatation. Based on our figures, there would be at least 400 patients with a dilated aorta in a year in our hospital alone. The prevalence of bicuspid aortic valve in our cohort (4.8%) was nearly three times higher than the general population where it is quoted as 1-2%. Our study also emphasised the established link between hypertension and aortic dilatation with an increased frequency in our cohort (63%) compared to the global prevalence (31%). Given the devastating sequelae of aortic dilatation and its increased prevalence in our patient population, it will be very important to keep these patients under routine surveillance and particularly those with hypertension.

Abstract
OBJECTIVE Recently, long noncoding RNAs (lncRNAs) have caught more attention for their role in the progression of many diseases. Among them, lncRNA GAS5 (Growth Inhibition Specificity 5) was studied in this research to identify how it affects the progression of atrial fibrillation (AF). PATIENTS AND METHODS In 40 patients with AF and 30 patients with sinus rhythm (SR), the GAS5 expression of the right atrial appendage (RAA) tissues was detected by the quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Moreover, the cell proliferation assay was conducted in AC16 cells transfected with GAS5 inhibitor and mimics, respectively. Furthermore, the qRT-PCR was performed to uncover the mechanism. RESULTS In the research, the expression of GAS5 in RAA tissues was decreased significantly in AF patients than that in SR ones. Moreover, overexpression of GAS5 inhibited cell growth in AC16 cells, while knockdown of GAS5 promoted cell growth in AC16 cells. In addition, further experiments revealed that ALK5 was a target of GAS5 and its expression in AF tissues negatively correlated to GAS5 expression. CONCLUSIONS These results indicate that GAS5 could inhibit cell proliferation of AF via suppressing ALK5, which may offer a new vision for interpreting the mechanism of AF development.

Abstract
Chemokines are small cytokines that are classified into four groups, one of which is called CC chemokines. In the present study, the full-length cDNA of a CCL25 chemokine was identified from black rockfish, Sebastes schlegelii (named as SsCCL25) by EST (expressed sequence tag) analysis. The cDNA of SsCCL25 consisted of a 5-terminal untranslated region (UTR) of 74 bp, a 3-UTR of 882 bp with a poly (A) tail, and an open reading frame (ORF) of 303 bp encoding a polypeptide of 100 amino acids with the putative molecular mass of 11.5 kDa. There was a SCY domain in the deduced amino acid sequence of SsCCL25. The phylogenetic relationships and syntenic analyses provided evidences for the identities of SsCCL25 with CCL25 group. The mRNA transcripts of SsCCL25 were expressed in all detected tissues and dominantly in liver, muscle and gill. Moreover, after Vibrio anguillarum stimulation, the mRNA expression levels of SsCCL25 were significantly up-regulated at 24 h (p < 0.05) in the liver and during 4-8 h (p < 0.05) in the spleen. Recombinant SsCCL25 protein induced chemotaxis of both control and LPS-stimulated peripheral blood leukocytes (PBL) and enhanced their resistance to bacterial infection in a dose-dependent manner. Furthermore, rSsCCL25 showed significant inhibitory effect on V. anguillarum and Edwardsiella tarda growth. All these results collectively indicated that SsCCL25 might contribute to the defense against microbe infection and function as a chemoattractant in black rockfish.

Abstract
BACKGROUND Pancreatic cancer is one of the most deadly cancers worldwide with a five-year survival rate of less than 5%. Chronic pancreatitis showed increased risk to develop pancreatic cancer, in which chronic inflammation of the pancreas may play a critical role. Cytokines play an indispensable role in inflammatory reaction and tumorigenesis. The purpose of this study was to determine whether cytokines were associated with survival and poor prognosis of pancreatic cancer. METHODS In this study, we examined levels of some important cytokines in the serum of 68 patients with pancreatic cancer, including CCL2, CCL17, CXCL-1, CXCL-5, G-CSF, GM-CSF, TGF-β and IFN-γ. RESULTS We found that high level of serum CCL2 was strongly associated with poor survival and prognosis, but no significant association with other clinicopathological features, including gender, age, location and TNM staging. For other cytokines, no significant correlation with poor survival and prognosis was found. CONCLUSION Our results suggest that serum level of CCL2 may serve as a potential marker for predicting the outcome of patients with pancreatic cancer.

Abstract
Abstract
Background
EMR is the standard of care for management of large non-invasive colonic polyps. Current guidelines recommend repeat colonoscopy within 6 months after EMR of large sessile polyps to assess the EMR site for residual adenoma. We reviewed the outcomes and compliance to these guidelines in patients at the University of Alberta Hospital (UAH) and surrounding 7 hospitals.
Aims
The primary outcome was the proportion of patients who received a follow up colonoscopy within 180 days.
Methods
Retrospective data was collected on consecutive patients who had a large polyp resection (size >2cm as documented per endoscopy report) from January 1st, 2014 to January 1st, 2016. Information was collected on patients from UAH as well as seven surrounding hospitals within the Edmonton geographic zone. Data was extracted from electronic health records.
Results
Of 258 patients identified patients, 250 had complete data. Of these 250 patients, 151 (60.4 %) were male and median age was 67 (IQR 60 - 72). Eighty-two cases (32.8%) were performed at UAH, with 168 cases (67.2%) at other hospitals. Polyps were removed by gastroenterologists (n=215, 86.0%), surgeons (n=26, 10.4%), and others (n=9, 3.6%).
Fifty-two patients (20.8%) had no formal follow up on electronic health records, while 198 patients (79.2%) had a repeat colonoscopy. 57 patients (29.1 %) had a repeat colonoscopy within 180 days. The median follow-up time was 224 days (IQR 172–365).
Of the 82 cases performed at UAH, 74 (90.2%) had follow up. Out of the 168 cases at the other hospitals, 124 (73.8%) had follow up (p<0.01). Sixteen (21.9%) and 41 (33.3%) cases were followed up within 180days at UAH and other hospitals, respectively (p=0.09).
Of the 74 cases with follow up at UAH, 12 (15.7%) had residual tissue confirmed by pathology. Of the 124 cases at other hospitals, 26 (21.0%) had follow up (p=0.41). Median polyp size was 2.5cm (IQR 2.0cm - 3.5cm)
Conclusions
Only 29.1% of patients with large sessile polyp removal in the Edmonton zone had a repeat colonoscopy within 180 days. Patients with large polypectomy performed at the academic hospital were more likely to be followed up compared to non-academic hospitals. Further validation studies with larger data sets are needed. These findings highlight the need for standardized pathways to appropriately manage and survey large polyps post-EMR.

Abstract
Hypoxia training can improve endurance performance. However, the specific benefits mechanism of hypoxia training is controversial, and there are just a few studies on the peripheral adaptation to hypoxia training. The main objective of this study was to observe the effects of hypoxia training on cutaneous blood flow (CBF), hypoxia-inducible factor (HIF), nitric oxide (NO), and vascular endothelial growth factor (VEGF). Twenty rowers were divided into two groups for four weeks of training, either hypoxia training (Living High, Exercise High and Training Low, HHL) or normoxia training (NOM). We tested cutaneous microcirculation by laser Doppler flowmeter and blood serum parameters by ELISA. HHL group improved the VO(2peak) and power at blood lactic acid of 4 mmol/l (P(4)) significantly. The CBF and the concentration of moving blood cells (CMBC) in the forearm of individuals in the HHL group increased significantly at the first week. The HIF level of the individuals in the HHL group increased at the fourth week. The NO of HHL group increased significantly at the fourth week. In collusion, four weeks of HHL training resulted in increased forearm cutaneous blood flow and transcutaneous oxygen pressure. HHL increases rowers' NO and VEGF, which may be the mechanism of increased blood flow. The increased of CBF seems to be related with improving performance.

Abstract
A number of resting-state functional magnetic resonance imaging (rs-fMRI) studies indicate dysfunction of large-scale brain networks underlying the pathophysiology of obsessive-compulsive disorder (OCD). Recent epidemiology studies show that the prevalence of female OCD patients is higher than that of males. However, the underlying neurobiology mechanism for female OCD patients remains not fully understood. In this study, we are aimed to explore the spontaneous brain neuronal activity in unmedicated female OCD patients using rs-fMRI methodology and fractional amplitude of low frequency fluctuations (fALFF) analysis. Additionally, we examine the relationship between fALFF changes and female OCD symptomatology. Increased fALFF values in right brainstem, right rectus, left middle temporal gyrus and right angular were found in OCD females. And decreased fALFF values in right cerebellum, left middle occipital gyrus, left insula, postcentral gyrus and left precentral gyrus were shown in female OCD patients. Moreover, the fALFF values in left precentral gyrus and left middle temporal gyrus were positively associated with patients YBOCS-Obsessions scores and HAMD scores, respectively. Our findings bring additional insights in understanding the pathophysiology of female OCD patients.

Abstract
Abstract
Background
An individual with bicuspid aortic valve (BAV) has a higher risk of developing aortic valve calcification (AVC) than people with tricuspid aortic valve. AVC in patients with BAV and TAV is known to be distinct in molecular level. But the epigenetic mechanism of AVC in patients with BAV is still undefined.
Purpose
To describe the role of microRNA (miRNA) in the AVC process of patients with BAV
Methods
We collected aortic valve samples of 5 patients with BAV, of which 2 have AVC and 3 of which have not. We performed RNA-seq technology on an Illumina Hiseq 2500/2000 platform to characterized all feathers of miRNAs in BAV. We used miRBase20.0 to look for known miRNA. Gene expression levels between groups of valves were compared with degeR to find out differential miRNAs. Then we predicated the target gene of miRNA by targetscan database. We performed the GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) enrichment analysis for the target gene candidates of differential miRNAs to predict the potential function of AVC specific miRNAs. A value of P<0.05 (2-sided) was considered to be statistically significant.
Results
Compared with noncalcified aortic valves. We found that 33 miRNAs were upregulated and 29 are significantly downregulated in calcified aortic valves. The analysis showed the total of 62 miRNAs to be significantly altered as shown in the heat map in Figure1. the target gene candidates of differential miRNAs were enriched in numerous Go terms including the following: binding, protein binding, ion binding, catalytic activity, localization. The significantly (P<0.05) affected pathways identified by KEGG pathway analysis are presented in table 1.

Abstract
Abstract
Background
Bronchial artery embolization (BAE) is considered the most effective nonsurgical emergent treatment for massive hemoptysis, which holds 50%-100% mortality rate if treated conservatively. The transradial approach (TRA) is becoming more popular than the transfemoral approach (TFA) in percutaneous coronary intervention.
Purpose
To compare systematically transradial approach and the transfemoral approach in bronchial artery embolization.
Methods
We had analyzed the clinical, angiographic and technical results of BAE performed between 2014 and 2017. In the present study 58 patients with massive hemoptysis that underwent BAE via the TRA (n=29) or the TFA (n=29) were analyzed. Clinical factors and outcomes in these two groups were compared.
Results
The prevalence of artery vasospasm significantly higher (P<0.05) and the puncture time was significantly longer (P<0.05) in patients who underwent BAE via the TRA rather than via the TFA. However, the complication rate was significantly lower (P<0.05) and the time bedridden (P<0.05) and artery compression time (P<0.05) were significantly shorter via the TRA than via the TFA.
Conclusion
These results suggest that BAE via the TRA was associated with a lower complication rate, and shorter artery compression time and bedridden time than BAE via the TFA. Transradial bronchial artery embolization is technically feasible and safe procedure.

Abstract
OBJECTIVE This study aimed to investigate the diagnostic value of the total amino-terminal propeptide of type 1 procollagen (P1NP) and C-terminal telopeptide of β-I collagen (β-CTX) in bone metastasis of patients with breast cancer and the correlation between them. PATIENTS AND METHODS The medical records of 73 patients were retrospectively analyzed. These patients with breast cancer were treated in Oncology, General Surgery, and Orthopedic Departments in The Third People's Hospital of Qingdao from March 2014 to April 2017, including 40 patients with bone metastasis (bone metastasis group) and 33 patients with no bone metastasis (non-bone metastasis group). Other 40 healthy people who received physical examination in the same period were selected as the control group. The expression of P1NP and β-CTX in plasma were detected by the Enzyme-linked immunosorbent assay, and the correlation between them was analyzed. RESULTS There were significant differences in P1NP and β-CTX concentrations among the three groups (p<0.05). The concentrations of P1NP in the control group and the non-bone metastasis group were significantly lower than that in the bone metastasis group (p<0.05); the concentrations of β-CTX in the control group and the non-bone metastasis group were significantly lower than that in the bone metastasis group (p<0.05). P1NP: AUC=0.852, sensitivity: 72.5%, specificity: 93.9%, CUT OFF=66.44. β-CTX: AUC=0.883, sensitivity: 85.0%, specificity: 84.8%, CUT OFF=69.8. Joint detection: AUC=0.952, sensitivity: 84.8%, specificity: 99.5%, CUT OFF=99.5. The results of the concentrations of P1NP and β-CTX in the bone metastasis group detected by the Pearson correlation analysis showed that their concentrations were positively correlated in the bone metastasis group (r=0.764, p<0.05). CONCLUSIONS P1NP and β-CTX in plasma have a high diagnostic value for bone metastasis of breast cancer and have important significance in the diagnosis of bone metastasis and disease monitoring.

Abstract
Rheumatoid arthritis is an autoimmune disease characterized by the synovitis of joints and the modulation of chronic inflammation determined by increased levels of inflammatory cytokines. This study aimed to investigate the characteristics of the immunological profile of the cells of the synovial membrane and the expression of IL-10 and IL-17 in a rheumatoid arthritis rat model in order to provide a targetdirected treatment for immunological control. Eighty female Wistar rats were randomly divided into a rheumatic arthritis model group (model group) and a control group, 40 animals per group. After the successful rheumatoid arthritis rat model was obtained, 10 animals were sacrificed from each group every week starting from the third week till the sixth week and the expression levels of CD3, CD21, and CD68 in the synovial region along with the blood level of IL-10 and IL-17 were assessed. At the four stages after modeling, the expression of CD3 in the model group increased compared with the control group (P less than 0.05). The expression of CD21 was different between the model group and the control group, but the difference did not reach statistical significance (P>0.05). The expression of CD68 determined at weeks 4 and 5 after modeling was increased compared to the control group (P less than 0.05). At 6 week after modeling, IL-10 levels in the model group were higher than those in the control group (P less than 0.05). At weeks 4 and 5 after modeling, the level of IL-17 in the model group increased compared to the control group (P less than 0.05). The level of IL-17 increased with the increase of synovial inflammation in the rheumatoid arthritis-induced rats, and the level of IL-10 increased as the inflammation subsided, which shows that both cytokines are related to the occurrence and development of rheumatoid arthritis and its inflammation.

Abstract
Virus-like particles encapsulating HBV-RNA represent a serum biomarker for assessing viral replication activity in clinical practice. However, baseline levels of serum HBV-RNA and their associations with viral replicative intermediates and liver disease in phases of chronic hepatitis B remain unknown. In this cross-sectional study, 102 patients were categorized into immune-tolerant (IT), HBeAg-positive immune active (HBeAg+IA), inactive carrier (IC) and HBeAg-negative immune active (HBeAg-IA) phases. HBV-RNA in serum samples and in 66 paired liver biopsies were quantified and correlated with serum ALT levels, histopathological scores and the levels of other viral replicative intermediates. Mean levels of serum HBV-RNA differed among phases, with the highest levels among IT (6.78 ± 0.83 log10 copies mL-1 ) patients, followed by HBeAg+IA (5.73 ± 1.16 log10 copies mL-1 ), HBeAg-IA (4.52 ± 1.25 log10 copies mL-1 ) and IC (2.96 ± 0.40 log10 copies mL-1 ) patients. Serum HBV-RNA levels correlated with HBV DNA in all phases, although correlations with other viral replicative intermediates weakened or disappeared when cases were stratified into phases. Distinct compositions of viral products were found among phases: the ratio of HBsAg to serum HBV-RNA was highest in IC patients, while the ratio of serum HBV-RNA to intrahepatic HBV-RNA and the ratio of intrahepatic HBV-DNA to intrahepatic HBV-RNA were significantly higher in IT patients. In conclusion, baseline levels of HBV-RNA and the composition of viral replicative intermediates differ significantly across the natural course of chronic HBV infection. These findings shed light on the nature of viral replication and pathogenesis of disease among different phases of chronic HBV infection.

Abstract
Previous studies have focused on the relationship between hepatitis B virus (HBV) infection and non-Hodgkin lymphoma (NHL). However, the results remain inconsistent and somehow conflicting in different subgroups. The aim of this study was to combine the findings of independent studies to comprehensively assess the association between HBV and NHL using a meta-analysis. Relevant studies were identified through structured keyword searches in PubMed, EMBASE and the China National Knowledge Infrastructure (CNKI) database, and 58 studies with a total of 53 714 NHL cases and 1 778 591 controls were finally included. Pooled estimates indicated a significantly increased NHL risk in HBV-infected individuals (summary odds ratio [sOR]: 2.50; 95% confidence interval [CI]: 2.20-2.83) regardless of the study design (case-control studies: sOR: 2.47; 95% CI: 2.16-2.82; cohort studies: sOR: 2.64; 95% CI: 1.78-3.91). Considerable heterogeneity was observed across studies that was primarily attributed to the NHL subtypes (meta-regression: P < .05). Overall, B-cell NHL (sOR: 2.46; 95% CI: 1.97-3.07) presented a stronger association with HBV infection than T-cell NHL (sOR: 1.67; 95% CI: 1.34-2.10). Within the B-cell NHL subtypes, HBV infection was significantly associated with diffuse large B-cell lymphoma (DLBCL, sOR: 2.06; 95% CI: 1.48-2.88) and follicular lymphoma (FL, sOR: 1.54; 95% CI: 1.11-2.12), but not with chronic lymphocytic leukaemia/small lymphocytic lymphoma (CLL/SLL) and Burkitt lymphoma. The results of this meta-analysis support a positive link between HBV infection and NHL development. Further investigations for the mechanisms underlying HBV-induced NHL are warranted.

Abstract
Measurements of the associated production of a Z boson with at least one jet originating from a b quark in proton-proton collisions ats = 8 TeV are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8fb - 1 . Z bosons are reconstructed through their decays to electrons and muons. Cross sections are measured as a function of observables characterizing the kinematics of the b jet and the Z boson. Ratios of differential cross sections for the associated production with at least one b jet to the associated production with any jet are also presented. The production of a Z boson with at least two b jets is investigated, and differential cross sections are measured for the dijet system. Results are compared to theoretical predictions, testing two different flavour schemes for the choice of initial-state partons.
