Abstract
OCT4, a marker of embryonic stem cells, is also a key transcription factor that plays a regulatory role in the self-renewal, proliferation and differentiation of stem cells. Previous studies showed that DNA methylation is involved in the regulation of OCT4 expression during the development and differentiation of embryonic stem cells. However, DNA methylation in the promoter region of OCT4 has not yet been discussed in human recurrent glioma. In this study, we assessed the specimens from 24 cases of recurrent glioma for OCT4 expression and methylation status, and commenced analyzing the correlation between the two by treating glioma cells with a demethylating agent in vitro. The results demonstrated that for the same cases, the expression of OCT4 in specimens of recurrent glioma was significant higher than that in primary glioma (P<0.05). DNA methylation levels in recurrent glioma decreased obviously compared with that in primary glioma (t=9.800, P=0.008). In vitro study indicated, following demethylation treatment, glioma cells had an increased OCT4 expression. These results suggest that DNA hypomethylation may be a key mechanism underlying the up-regulation of OCT4 in the recurrence of glioma, which facilitates the understanding of the role of stem cells and the exploration of novel strategies for the treatment of recurrent glioma.

Abstract
Congenital hepatic arteriovenous fistulae (CHAVF) are direct communications between the hepatic artery and portal vein or hepatic vein. Clinical symptoms of CHAVF depend mainly on the location, duration, and blood flow volume of the fistulae, which are manifested by portal hypertension, hepatic fibrosis, cardiac enlargement, and eventually heart failure. Here we report a female patient aged 54 who was first admitted to our hospital due to recurrent chest tightness and palpitations in March 2014. Metoprolol tartrate and diltiazem hydrochloride were prescribed to control the symptom since nothing unusual was found in coronary angiography and abdominal ultrasound. Until April 2015, the patient's syndrome relapsed and abdominal computed tomography angiography and digital subtraction angiography revealed diffuse arteriovenous fistulae between the branches of hepatic artery and vein. Subsequently, 3 attempts at hepatic arterial embolization were performed; however, her abdominal pain aggravated and her heart discomfort could not be relieved eventually. Therefore, orthotopic liver transplantation as the salvage treatment was performed using a hepatic graft from a 19-year-old cardiac-death donor performed on January 1, 2017. Upon operation, the enlarged right hepatic artery whose diameter was approximately 1.5 cm in this recipient. And we also demonstrated a novel manner that the graft's celiac artery patch was anastomosed to the recipient's proper hepatic artery and gastroduodenal artery patch, which could reduce the blood flow successfully. The patient recovered uneventfully and was discharged home on the postoperatively 15th day. Since her liver transplantation, she has not complained of cardiac discomfort and abdominal pain, and her heart size has returned to normal on echocardiography. The hepatic artery peak velocity reduced to normal and the heart shadow also recovered. Nevertheless, for complex and diffuse intrahepatic vascular fistulae after failed hepatic artery embolization, liver transplantation should be strongly considered as the definitive treatment of choice.

Abstract
High-risk human papillomavirus (HPV) is an important pathogenic factor for cervical cancer and understanding the mechanism of HPV gene transcription is important for the prevention and therapy of HPV related cervical cancer. This study aimed to investigate the role of nitric oxide (NO) in the regulation of HPV gene transcription. SiHa cells containing integrated HPV16 were treated with NO donor DETA-NO and cell proliferation and cytotoxicity were determined. HPV gene transcription was detected by real-time PCR. We found no significant cytotoxic effects on SiHa cells when the concentration of DETA-NO was less than 0.5 mmol/l. The transcription of HPV E6 gene was inhibited by DETA-NO in a dose-dependent manner and the best inhibitory effect was observed at 0.5 mmol/l DETA-NO. In addition, ERK inhibitor U0126 decreased the transcription of HPV E6 gene at the concentration of 30 μmol/l. In conclusion, NO inhibits the transcription of HPV E6 gene and probably involves MAPK signaling pathway. Keywords: SiHa cells; nitric oxide; MAPK pathway; HPV transcription.

Abstract
Current researches have determined the significance of C-C chemokine receptor (CCR)6 expression as either a marker of T helper cells (Th) or an effector and regulator of T cell function. However, the roles of CCR6 in the pathogenesis of immune thrombocytopenia (ITP) are unclear. In this study, we aimed to investigate the phenotype and functional characteristics of circulating CCR6+ T cells in blood from chronic ITP patients and healthy controls. We found that the frequency of CCR6+ CD4+ cells was higher in ITP patients than in healthy controls. Anti-CD3/anti-CD28 stimulation induced rapid expansion of CCR6+ CD4+ cells in ITP patients. CCR6+ CD4+ cells had a phenotype of activated cells and predominantly expressed CD45RO. Forkhead box protein P3 (FoxP3) and CD25-positive cells were exclusively detected within the CCR6+ CD4+ cells. In ITP patients, CCR6+ regulatory T cells (Treg ) were decreased and positively correlated with platelet counts and transforming growth factor (TGF)-β plasma levels. In contrast to CCR6- counterparts, CCR6+ CD4+ cells produced higher levels of interleukin (IL)-17A. The frequency of CCR6+ Th17 was higher in ITP patients and positively correlated with IL-17A levels in supernatant. Most importantly, CCR6+ CD4+ cell subpopulations, but not CCR6- CD4+ , were closely correlated to treatment response of ITP patients. These findings suggest that circulating CCR6+ CD4+ cells in ITP patients have characteristics of activated memory Th17 phenotype and could be used to monitor disease activity and treatment response.

Abstract
Pancreatic fistula is a common and serious complication after pancreatic surgery. Pancreatic fistula, intra-abdominal infection and hemorrhage are known as the " lethal triad" after pancreatic surgery, which seriously affect the curative efficacy of operation. Although the incidence of pancreatic fistula has not been significantly reduced, there have been a large number of studies on the risk factors of pancreatic fistula and the means of prevention and therapy, which try to minimize the harm of pancreatic fistula. In this article we review the recent development of the latest definition, high risk factors and treatment of postoperative pancreatic fistula according to relevant literatures at home and abroad, aiming at summarizing the research advances on the therapy of pancreatic fistula after pancreatic surgery.

Abstract
Objective: This survey followed the birth population-based study conducted in 2010 in Huai'an, Jiangsu Province, with the aim to estimate perinatal-neonatal mortality and preterm birth rate in emerging regions with similar maternal-fetal and neonatal care conditions in China.Materials and methods: Data of total births in 2015 were prospectively collected by regional perinatal network collaboration in Huai'an, a subprovincial region with a population of 5,644,500 and gross domestic production of 9082 USD per capita.Results: The 59,424 birth registries (including 59,023 live births and 167 stillbirths) corresponded to a birth rate of 10.5‰ and a Male-to-female ratio of 113.7:100. All births there were from 85, 16, and 6 level I, II, and III hospitals, with a delivery rate of 30.4, 40.2, and 29.4%, respectively. Of all births, 14.1% had pregnancy-associated comorbidities and complications, 54.4% (32,226/59,190) had cesarean delivery, and multiple pregnancies and birth defects occurred in 2.1% (1,250) and 5.5‰ (324), respectively. The mean birth weight was 3448 ± 507 g with 13.9% being macrosomia, and 2.86% (1695/59,190) low birth weight. Preterm birth rate was 4.06% (2404/59,190) with a mortality rate of 8.5%. There were 94.5% recorded as healthy newborns and 5.5% (3263) requiring hospitalization after birth. The perinatal and neonatal mortality rate was 5.2‰ (167 stillbirths, 139 early neonatal deaths) and 4.0‰, respectively. Compared with the 2010 survey, these data demonstrated generally improved status of perinatal-neonatal healthcare.Conclusions: The low rates of perinatal-neonatal mortality, preterm birth and preterm mortality suggest that the concept and study protocol of perinatal-neonatal healthcare in Huai'an may serve as the benchmark for estimating regional vital statistics and perinatal and neonatal outcomes.

Abstract
Background: Programmed cell death protein 1 (PD-1), an immune checkpoint molecule, has recently been recognized as a predictive and prognostic biomarker in several malignant tumors, but its diagnostic value remains largely unknown. Aim: We aimed to investigate the differential diagnostic efficiency of PD-1 and other immune molecules, and propose a panel of immune molecules combined with cancer antigen 15-3 (CA15-3) to distinguish breast cancer (BC) from benign breast disease (BBD). Methods: Ninety-one eligible BC patients and 31 BBD patients were enrolled. Pretreatment peripheral blood was collected and tested for mRNA expression of PD-1, cytotoxic T lymphocyte antigen 4 (CTLA-4), forkhead box P3 (FOXP3), transforming growth factor beta (TGF-β), interleukin-10 (IL-10), IL-2 receptor alpha (IL-2Rα), and cluster of differentiation 28 (CD28) by quantitative real-time PCR. Results: The diagnostic areas under curve (AUCs) of PD-1, IL-2Rα, and IL-10 for BC-BBD discrimination were 0.764, 0.758, and 0.743, respectively. The diagnostic efficiencies of these 2 parameters in distinguishing early-stage or advanced BC from BBD were consistent with a role in BC-BBD discrimination. A panel of PD-1 + IL-10 + IL-2Rα + CA15-3 showed the highest AUC (0.862), with sensitivity of 0.933 and specificity of 0.724, for BC-BBD discrimination. In addition, for early-stage BC discrimination, this panel also had the highest AUC (0.811), with a sensitivity of 0.933 and specificity of 0.614, while for advanced BC discrimination, a panel of PD-1 + IL-10 + CA15-3 exhibited the highest AUC (0.896), with a sensitivity of 0.933 and specificity of 0.783. Conclusion: These data indicate that the panel containing PD-1, IL-2Rα, IL-10, and CA15-3 can effectively discriminate BC from BBD with a high efficiency. After further confirmation, it could be used to complement conventional imaging modalities, especially in discriminating early-stage BC from BBD.

Abstract
Background: The clinical significance of programmed cell death 1 (PD-1) and cytotoxic T lymphocyte-associated protein 4 (CTLA-4) expression on tumor infiltrating lymphocytes in breast cancer patients has been confirmed, while that of peripheral blood cells derived immune molecules remain unclear. Aim: We aimed to investigate the clinical importance of immune molecules, including PD-1 and CTLA-4, expression in peripheral blood cells of breast cancer patients, especially in terms of the relationship between immune molecules and estrogen receptor (ER)/progesterone receptor (PR) status, as well as their prognostic values. Methods: We enrolled 109 breast cancer patients, including 52 cases before surgery and neoadjuvant treatment (PreS group), 18 cases postsurgery and adjuvant chemoradiotherapy (PostS group), 39 metastatic cases presalvage treatment (Met group), and 21 age- and sex-matched healthy volunteers). The mRNA abundance of PD-1, CTLA-4, IL-2 receptor alpha (IL-2Rα), and cluster of differentiation 28 (CD28), forkhead box P3 (FOXP3), transforming growth factor beta (TGF-β), and interleukin-10 (IL-10) in pretreatment peripheral blood were analyzed by quantitative real-time PCR. Results: ER+ breast cancer patients showed significant higher mRNA levels of PD-1, CTLA-4, IL-2Rα, and CD28 with fold changes of 10.8, 2.4, 5.0, and 3.8, respectively ( P < 0.05) than that of ER− cases. Similarly, PR+ patients showed increased levels of PD-1, CTLA-4, and CD28 with fold changes of 6.7, 2.0, and 2.5, respectively ( P < 0.05) comparing to that of PR− cases. Patients in PreS group and Met group showed higher mRNA levels of PD-1, CTLA-4, IL-2Rα, CD28, FOXP3, TGF-β, and IL-10 than PostS group and healthy volunteers. Univariable analysis revealed that high PD-1 expression was associated with poorer progression-free survival (PFS) in metastatic breast cancer patients (5.9 vs 14.6 months, HR: 2.47, 95% CI: 1.22-5.02, P = 0.046). Meanwhile, the prognostic value of PD-1 was remained in multivariate analyses (HR: 2.22, 95% CI: 1.04-4.73, P = 0.039). Conclusion: Increased PD-1, CTLA-4, and CD28 mRNA abundance were showed in breast cancer patients and ER+/PR+ cases, which may provide the rationale for combining checkpoint inhibitors with endocrine therapy for breast cancer treatment. Furthermore, PD-1 is a promising prognostic biomarker for metastatic breast cancer.

Abstract
The Src homology and collagen A (ShcA) adaptor protein that binds to tyrosine kinase receptors. ShcA plays a role in insulin signaling, stress resistance and energy metabolism. The 66-kDa Src homology 2 domain-containing protein (p66shc) belongs to the ShcA family and has been associated with reactive oxygen species (ROS); increased ROS is involved in the pathology of lupus nephritis (LN). However, whether ShcA can act as a biomarker for oxidative injury in LN is unknown. This study is aimed to investigate the ShcA expression in kidney tissues from patients presenting with LN and the association between ShcA expression and clinical parameters. Renal biopsy tissues were obtained from 62 LN, 20 primary membranous nephropathy (MN) and 10 other secondary MN patients. ShcA was measured by immunofluorescence. The expression of ShcA in the membranous lupus nephritis (class V) group showed a higher trend but there were no significant differences compared with pure mesangial disease (class II) and proliferative (Class III/IV) lupus nephritis. ShcA deposits were negative in primary and other secondary MN. ShcA might act as a new biomarker and a diagnostic tool to identify membranous lupus nephritis with other MN.

Abstract
Objective: To investigate the safety and efficiency of small incision minimally invasive approach pancreatic necrosectomy in the treatment of infected pancreatic necrosis. Methods: The data of 164 patients who underwent small incision minimally invasive approach pancreatic necrosectomy for infected pancreatic necrosis at Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University from January 2012 to December 2016 were analyzed retrospectively.Among 164 patients, there were 102 male and 62 female patients.The median age was 46 years(ranging from 19 to 79 years). One hundred and one patients(61.6%) suffered from severe acute pancreatitis and 63 patients(38.4%) suffered from moderately severe acute pancreatitis.Following step-up approach principle, the surgical procedures were performed for 131 patients(79.9%) who suffered from sepsis which could not be alleviated via percutaneous catheter drainage(PCD). The other 33 patients(20.1%) who did not undergo PCD directly took small incision minimally invasive approach pancreatic necrosectomy.Preoperative CT images were used to determine the location of the lesion.The PCD puncture points or the points where the abscess was closest to the skin were chosen as the incision.Gradually, the small incision minimally invasive approach pancreatic necrosectomy were performed via cutting all layers into the abscess. Results: The median time from the onset of symptom to first operation was 32 days(ranging from 23 to 45 days). The average hospital stay was 46 days(ranging from 29 to 103 days). The average number of drainage tubes placed was 4 pieces(ranging from 2 to 8 pieces). Ninety-two patients(56.0%) underwent minimal access retroperitoneal pancreatic necrosectomy. Thirty-six patients(22.0%) underwent minimal invasive approach lesser omentum sac pancreatic necrosectomy.Thirty-six patients(22.0%) underwent minimal invasive approach lesser omentum sac pancreatic necrosectomy combined with minimal access retroperitoneal pancreatic necrosectomy.A total of 148 cases(90.2%) were cured via minimally invasive approach pancreatic necrosectomy, 8 cases(4.9%) were cured after transfering to open pancreatic necrosectomy.The cure rate was 95.1%(156/164). The mainly postoperative complications included pancreatic fistula(25 cases), intra-abdominal hemorrhage(10 cases), gastric fistula (2 cases), duodenal fistula(4 cases) and colonic fistula(3 cases). The overall incidence rate of complications was 26.8%(44/164). Eight cases were dead after surgery and the in-hospital mortality was 4.9%(8/164). Conclusion: In summary, small incision minimally invasive approach pancreatic necrosectomy is an effective way to clean up necrotic tissue, improve the drainage, reduce complications in dealing with infected pancreatic necrosis.

Abstract
Objective: To investigate the effect and mechanism of celastrol on free fatty acids (FFAs)-induced HepG2 cells. Methods: Cultured human HepG2 cells were transfected with toll-like receptor 4 (TLR4) siRNA, and the interference efficiencies were examined by real-time PCR. HepG2 cells were treated with FFAs and celastrol, and the untreated cells were used as a normal control (NC). Deposition of lipids in the HepG2 cells were visualized by Oil Red O staining. The protein expression of TLR4 and downstream inflammatory mediators [myeloid differentiation factor 88 (MyD88), nuclear factor (NF)-κBp65, interleukin (IL)-1β and tumor necrosis factor α (TNF-α)] in the HepG2 cells were determined by Western blotting. The significance of the data obtained was evaluated using analysis of variance (ANOVA). Results: Red lipid droplets were extensively deposited in HepG2 cells after 0.5 mmol/L FFAs induction and significantly decreased in the celastrol-treated group. The protein expression of TLR4 and downstream inflammatory mediators (MyD88, NF-κBp65, IL-1β and TNF-α) in the FFAs-induced HepG2 cells increased significantly compared with those of the NC group (all P<0.05), and were suppressed in TLR4 siRNA-treated and celastrol-treated group (TLR4: 0.69±0.14, 1.63±0.12 vs 2.46±0.23; MyD88: 1.21±0.12, 1.35±0.18 vs 1.62±0.19; NF-κBp65: 1.69±0.14, 1.54±0.36 vs 2.19±0.47; IL-1β: 1.51±0.16, 1.45±0.38 vs 1.82±0.27; TNF-α: 1.60±0.14, 1.41±0.29 vs 1.88±0.19) (all P<0.01). Co-treatment with TLR4 siRNA and celastrol further reduced the expression of inflammation mediators compared with those of the TLR4 siRNA-treated group (MyD88: 1.09±0.23 vs 1.21±0.12; NF-κBp65: 1.24±0.20 vs 1.69±0.14; IL-1β: 1.28±0.31 vs 1.51±0.16; TNF-α: 1.10±0.29 vs 1.60±0.14) (all P<0.01). Conclusion: Celastrol exerts its protective effect partly via inhibiting the TLR4-mediated signaling pathways in the steatotic HepG2 cells.

Abstract
Cisplatin (CP) is one of the most effective and widely used compounds in the treatment of disease, including cancer, but is known to induce toxicity in patients. Rutin (RUT) is a flavonoid glycoside from Sophora japonica L. that has been shown to possess antioxidative, anti-inflammatory, and antiviral properties. RUT is also known to attenuate cardiotoxicity, isoproterenol-induced cardiac fibrosis, and ischemia/reperfusion-associated hemodynamic alteration, and prevents high glucose-induced renal glomerular endothelial hyperpermeability. In this study, we investigated the effect of RUT on CP-induced nephrotoxicity. CP was used to induce toxicity in human mesangial cells (HMCs), HMCs were pretreated with different concentrations of RUT before being exposed to 10 μg/mL of CP. A positive group was pretreated with antioxidant agent N-acetylcysteine prior to CP administration. At doses between 12.5 and 25 μM, RUT prevented CP-induced reduction in cell viability. Treatment with RUT suppressed intracellular reactive oxygen species and malonic dialdehyde levels and inhibited cell apoptosis. RUT reversed the CP-induced upregulation of p53, cleaved-caspase-3, and increased pro-caspase-3 and pro-caspase-9 levels. In conclusion, the RUT can relieve CP-induced nephrotoxicity by inhibiting the p53/caspase signaling pathway.

Abstract
BACKGROUND Pre-operative tissue diagnosis for suspected malignant biliary strictures remains challenging. AIM To develop evidence-based consensus statements on endoscopic tissue acquisition for biliary strictures. METHODS The initial draft of statements was prepared following a systematic literature review. A committee of 20 experts from Asia-Pacific region then reviewed, discussed, and modified the statements. Two rounds of independent voting were conducted to reach a final version. Consensus was considered to be achieved when 80% or more of voting members voted "agree completely" or "agree with some reservation." RESULTS Eleven statements achieved consensus. The choice of tissue sampling modalities for biliary strictures depends on the clinical setting, the location of lesion, and availability of expertise. Detailed radiological and endoscopic evaluation is useful to guide the selection of appropriate tissue acquisition technique. Standard intraductal biliary brushing and/or forceps biopsy is the first option when endoscopic biliary drainage is required with an overall (range) sensitivity and specificity of 45% (26%-72%) and 99% (98%-100%), and 48% (15%-100%) and 99% (97%-100%), respectively, in diagnosing malignant biliary strictures. Probe-based confocal laser endomicroscopy and fluorescence in situ hybridisation using 4 fluorescent-labelled probes targeting chromosomes 3, 7, 17 and 9p21 locus may be added to improve the diagnostic yield. Cholangioscopy-guided biopsy and EUS-guided tissue acquisition can be considered after prior negative conventional tissue sampling with an overall (range) sensitivity and specificity of 60% (38%-88%) and 98% (83%-100%), and 80% (46%-100%) and 97% (92%-100%), respectively, in diagnosing malignant biliary strictures. CONCLUSION These consensus statements provide evidence-based recommendations for endoscopic tissue acquisition of biliary strictures.

Abstract
Objective: To analyze the clinical features of acute diffuse pulmonary exudative disorders. Methods: The data were collected from patients who were hospitalized in respiratory intensive care unit (RICU) of Beijing Chaoyang Hospital affiliated to the Capital Medical University during January 2009 to December 2011, and had acute clinical course with imaging findings of diffuse pulmonary infiltrated shadows (similar to acute respiratory distress syndrome (ARDS)). The causes of disease and clinical features were analyzed. Results: A total of 86 patients with acute diffuse pulmonary exudative disorders were included. Sixty-two (72.1%) were males, with a mean age of (58.6±16.4) years old; 24(27.9%) were females, with a mean age of (48.2±18.3) years old. The duration of the disease before administration was (11.5±5.2) days, and RICU stay was (15.5±9.5) days, with hospital mortality of 40.7% and the average hospitalization cost of 101 thousand RMB. The main cause was infection, which occurred in 53 cases (61.6%) (virus in 21 cases, bacteria in 14 cases, fungus in 11 cases, pneumocystis in 15 cases and others in 3 cases, mixed infection in 11 cases). Interstitial pneumonia occurred in 12 cases (idiopathic interstitial pneumonia in 9 cases: cryptogenic organizing pneumonia in 3 cases, the acute exacerbation of idiopathic pulmonary fibrosis in 3 cases, nonspecific interstitial pneumonia in 1 case, acute interstitial pneumonia in 2 cases, and connective tissue disease in 3 cases), aspiration pneumonia in 10 cases, acute left heart failure in 6 cases, and exogenous pulmonary ARDS in 5 cases. Conclusions: The main cause of acute diffuse pulmonary exudative disorders is pulmonary infection, followed by interstitial pneumonia. The hospital mortality and hospitalization cost are high.

Abstract
BACKGROUND AND PURPOSE An accurate evaluation of the World Health Organization grade and cellular proliferation is particularly important in meningiomas. Our aim was to prospectively evaluate and compare diffusional kurtosis imaging, DTI, and DWI metrics in determining the grade and cellular proliferation of meningiomas. MATERIALS AND METHODS Ninety-six consecutive patients with histopathologically confirmed meningiomas were included in this study. Mean kurtosis, radial kurtosis, axial kurtosis, fractional anisotropy, mean diffusivity, and ADC were semiautomatically obtained in the solid components of tumors. Each normalized diffusion value was compared between high-grade meningiomas and low-grade meningiomas using the Mann-Whitney U test. Receiver operating characteristic, multiple logistic regression, and Pearson correlation analysis were used for statistical evaluations. RESULTS Diffusional kurtosis imaging metrics (mean kurtosis, radial kurtosis, and axial kurtosis) were significantly higher in high-grade meningiomas than in low-grade meningiomas (P ≤ .001). Mean diffusivity and ADC were significantly lower in high-grade meningiomas than in low-grade meningiomas (P = .003 and .002). Mean kurtosis had significantly greater area the under curve values than mean diffusivity and fractional anisotropy in differentiating high-grade meningiomas from low-grade meningiomas (P = .038 and .002). Mean kurtosis was the only variable that could be used to independently differentiate high-grade meningiomas and low-grade meningiomas (P < .001). Significant correlations were found between the Ki-67 labeling index and kurtosis metrics (P < .001), as well as for mean diffusivity and ADC (P = .004, and .007). CONCLUSIONS Compared with other diffusion metrics, mean kurtosis may serve as an optimal parameter for evaluating and predicting the meningioma grade. Moreover, diffusion metrics may potentially reflect cellular proliferation.

Abstract
Extracorporeal photopheresis (ECP) represents an alternative to immunosuppression as a means of reducing rejection after thoracic organ transplantation. The mechanism by which ECP exerts its protective effects, until now, has remained elusive. Infusion of ECP-treated splenic lymphocytes (PUVA-SP) can induce CD4+CD25highFoxp3+ regulatory T cells. However, the regulatory effect of PUVA-SP on B cells remains poorly understood. In the present study, we measured IL-10 secretion from CD19+ B cells of peripheral blood mononuclear cells. Our results demonstrate that infusion of PUVA-SP (PUVA-BSP from BALB/c or PUVA-CSP from C57BL/6 mice), in the absence of an immunosuppressant, significantly promotes skin allograft survival. This effect was associated with upregulation of circulating regulatory B cells exhibiting preferential IL-10 secretion and a shift of cytokine profile from helper T cell type 1 to helper T cell type 2. Our results suggest that effective treatments involving infusion of PUVA-SP is likely related not only to the modulation of T cell and regulatory T cell functions but also to the function of B cell and regulatory B cells.

Abstract
Objective: To investigate the effect of Berberine on renal tubulointerstitial injury and its potential mechanism in rats with type 2 diabetes mellitus (T2DM). Methods: Thirty Sprague-Dawley rats were randomly divided into 3 groups: normal control rats (NC group), diabetic rats without drug treatment (DM group), diabetic rats treated with Berberine (BBR group) for 8 weeks. At the end of the study, blood and urine samples were collected for biochemical examination, and tubulointerstitial fibrosis was quantified by Hematoxylin and Eosin (HE) and Masson staining. The expressions of E-cadherin (E-cad), α-smooth muscle actin (α-SMA), nuclear factor-κB (NF-κB) and monocyte chemoattractant protein 1 (MCP-1) were detected by immunohistochemistry analysis, real-time polymerase chain reaction (RT-PCR) and Western blot analysis. Results: 24 h urinary microalbumin (mAlb)[(170.5±58.1) vs (253.7±53.0) mg]and urinary N-acetyl-glucosaminidase (NAG)[(33.5±7.2) vs (49.5±9.3)U/L]in diabetic rats were significantly decreased by BBR treatment(both P<0.05). The apparent renal tubulointerstitial injury was found in the DM group, which was ameliorated by BBR treatment. The expression of α-SMA, NF-κB and MCP-1 were significantly decreased, accompanied by increased expression of E-cad in BBR-treated DM rats (all P<0.05). Conclusion: BBR could ameliorate renal tubulointerstitial injury in diabetic rats, the mechanism of which may be associated with the amelioration of epithelial-mesenchymal transition (EMT) through suppressing the expression of the NF-κB and MCP-1.

Abstract
The retroperitoneum space comprises anterior pararenal space, perirenal space and posterior pararenal space. Pancreas is a retroperitoneal organ and located in the anterior pararenal space of the retroperitoneum. Left and right sides anterior pararenal space are potentially communicated, which contains many adipose tissues and a little connective tissues. The exacerbation of acute pancreatitis results in the lesion spreading into adjacent area of pancreas in the retroperitoneal space. In addition, the lesion could spread into bare area of stomach, posterior colonic region, subperitoneal space and pelvic retroperitoneal space through the same anatomical space or communicating space. Due to the fascia destruction by pancreatic enzymes or the lesion directly diffuse through the weak fascia, the lesion could also diffuse across fascia to perirenal space, posterior pararenal space, the peritoneal cavity and abdominal wall. Finally, a series of complications are developed. The diffusion paths of acute pancreatitis are complex and diverse. Familiarity with these diffusion paths is useful for determining the severity and guiding therapy.

Abstract
UNLABELLED This study presents the clinical and biochemical profiles of patients with PHPT between 2005 and 2016 at our center. Most PHPT patients in China show symptomatic features. The number of symptomatic and asymptomatic patients increased during that time, and the number of individuals with parathyroid carcinoma is now increasing. INTRODUCTION Over the last decade, the prevalence of primary hyperparathyroidism (PHPT) has increased sharply, and the number of individuals with parathyroid cancer is still trending upward. Little is known about the clinical outlook of the disease over the last decade in China. The aim of this study was to describe the clinical characteristics of PHPT patients at our center from January 2005 to December 2016. METHODS Two hundred sixty patients with PHPT visiting Shanghai Jiao Tong University Affiliated Sixth People's Hospital were enrolled retrospectively. The clinical manifestations and biochemical abnormalities of these patients were analyzed. RESULTS Among all patients, 73.1% had symptomatic PHPT, while the number of symptomatic and asymptomatic patients increased 1 to 2.5 times and 1.5 to 3 times, respectively, from 2005 to 2016. Bone pain and single adenoma were the most frequent signs and pathological results. The patients with parathyroid carcinoma over the last 5 years accounted for 90% (9/10) of all parathyroid carcinoma patients from 2005 to 2016, and parathyroid carcinoma patients had higher levels of serum calcium, parathyroid hormone (PTH), and serum creatinine (P < 0.05) than parathyroid hyperplasia and parathyroid adenoma patients. CONCLUSIONS Most patients with PHPT in China still exhibit classic clinical and biochemical features. Both symptomatic and asymptomatic patients have increased over the last 12 years. Although the proportion of parathyroid carcinoma was small, a noticeable upward tendency was observed at our center.

Abstract
DNA vaccination is a promising cancer treatment due to its safety, but poor immunogenicity limits its application. However, immunoadjuvants, heterogeneous prime-boost strategies and combination with conventional treatments can be used to improve the antitumour immune effects. A CpG motif and interleukin-2 (IL-2) cytokine are often used as adjuvants. In this study, a DNA vaccine containing a CpG motif was constructed to evaluate its adjuvant effect. The results show that the cytotoxicity of the DNA vaccine was increased fivefold, and survival lifetime was prolonged twofold by the CpG motif adjuvant. To simplify the industrial production process, a bicistronic plasmid was constructed to carry the fusion genes of survivin/MUC1 (MS) and IL-2 and with a CpG motif in its backbone. The results showed that the antitumour effect of the bicistronic vaccine was the same as that of the two vaccine co-injected regime. Furthermore, the vaccine could suppress metastatic tumour foci by 69.1% in colorectal carcinoma-bearing mice. Moreover, the vaccine induced survivin- and MUC1-specific immune responses in splenocytes and induced the immune promoting factor CCL-19 and GM-CSF upregulated, while metastatic-associated factor MMP-9 and immunosuppressing factor PD-L1 downregulated in tumour tissue. When combining the vaccine with the chemotherapy drug oxaliplatin, the survival was prolonged by about 2.5-fold. In conclusion, the DNA vaccine containing a CpG motif in bicistronic form showed good effects on colorectal cancer by inhibiting both tumour growth and metastasis, and combination with oxaliplatin could improve its antitumour effects.

Abstract
Bromodomain extraterminal protein (BETP) inhibitors transcriptionally repress oncoproteins and nuclear factor-κB (NF-κB) target genes that undermines the growth and survival of mantle cell lymphoma (MCL) cells. However, BET bromodomain inhibitor (BETi) treatment causes accumulation of BETPs, associated with reversible binding and incomplete inhibition of BRD4 that potentially compromises the activity of BETi in MCL cells. Unlike BETi, BET-PROTACs (proteolysis-targeting chimera) ARV-825 and ARV-771 (Arvinas, Inc.) recruit and utilize an E3-ubiquitin ligase to effectively degrade BETPs in MCL cells. BET-PROTACs induce more apoptosis than BETi of MCL cells, including those resistant to ibrutinib. BET-PROTAC treatment induced more perturbations in the mRNA and protein expressions than BETi, with depletion of c-Myc, CDK4, cyclin D1 and the NF-κB transcriptional targets Bcl-xL, XIAP and BTK, while inducing the levels of HEXIM1, NOXA and CDKN1A/p21. Treatment with ARV-771, which possesses superior pharmacological properties compared with ARV-825, inhibited the in vivo growth and induced greater survival improvement than the BETi OTX015 of immune-depleted mice engrafted with MCL cells. Cotreatment of ARV-771 with ibrutinib or the BCL2 antagonist venetoclax or CDK4/6 inhibitor palbociclib synergistically induced apoptosis of MCL cells. These studies highlight promising and superior preclinical activity of BET-PROTAC than BETi, requiring further in vivo evaluation of BET-PROTAC as a therapy for ibrutinib-sensitive or -resistant MCL.

Abstract
Residual feed intake (RFI) is a measure of feed efficiency. Pigs with low RFI have reduced feed costs without compromising their growth. For marker-assisted selection, it is helpful to identify genes or genetic markers associated with RFI in animals with improved feed efficiency at an early age. Using Illumina's PorcineSNP60 BeadChip, we performed a pilot genome-wide association study of 217 Junmu No. 1 white male pigs phenotyped for RFI. Two-step and one-step methods were used separately to identify associated SNPs. Both methods obtained similar results. Twelve SNPs were identified as significantly associated with RFI at a Bonferroni adjusted P-level < 9.7 × 10-7 , and 204 were found to have suggestive (moderately significant) association with RFI at P < 5 × 10-5 . NMBR, KCTD16, ASGR1, PRKCQ, PITRM1, TIAM1 and RND3 were identified as candidate genes for RFI.

Abstract
T cell receptor (TCR) diversity is clearly related to protection from infection. However, the characteristics of TCR diversity in neonates are not clear. In this study, we investigated the TCR diversity of neonates with sepsis. Twenty neonates with severe sepsis and eight matched neonates without infection were enrolled in the study. For the neonates with sepsis, EDTA-anticoagulated blood was collected on day 1 after the diagnosis of sepsis and on day 7 of treatment. For the neonates without infection, blood was collected one time. DNA was extracted from peripheral blood mononuclear cells. The complementarity determining region 3 (CDR3) gene was analysed by multiplex PCR and high-throughput sequencing. The CDR3 types and lengths were similar in patients and healthy controls. There was a significant difference in VJ gene usage among the three groups. Compared to the healthy neonates, the neonates with sepsis had different VJ pairs and generated different clonotypes. Although the TCR β-chain diversity was generally lower in the neonates with sepsis, there was no significant difference in TCR β-chain diversity between the patients and the healthy controls. Our data showed the characteristics of the TCR repertoire in neonates with sepsis, which represents a potentially valuable data set. This result is useful for understanding neonatal susceptibility to infection.

OBJECTIVE The aim of this study was to analyze the depolymerization in metalloproteinase (ADAM17), epidermal growth factor receptor (EGFR), the expression of Ki-67 of glioma patients and the correlations with malignancy. PATIENTS AND METHODS 53 brain glioma samples resected from patients who had surgery from April 2015 to May 2016 at Chinese People's Armed Police Force General Hospital were selected. According to the degree of malignancy: 22 patients were divided into a deterioration group (stage I to II); 31 patients in highly deteriorated group (stage III to IV); 14 brain tissue samples of traumatic decompression from the hospital as control group. The immunohistochemical method was used to detect the expression of ADAM17, EGFR, and Ki-67 in three groups, and the correlation between the expression of ADAM17, EGFR, and Ki-67. Thus, the stages of malignancy were analyzed. RESULTS ADAM17, EGFR, and Ki-67 had no expression or weak expression in the control group, and increased in the low stage of deterioration group; the differences were statistically significant (p < 0.05). The positive expression rates of ADAM17, EGFR, and KI-67 were significantly higher in the high deterioration group than that in the control group (p < 0.05). Moreover, the analysis showed that the expression of ADAM17, EGFR, and Ki-67 were positively correlated with the stage of malignancy (R = 0.823, p = 0.000; R = 0.804, p = 0.000; R = 0.811, p = 0.000). CONCLUSIONS The results suggested that there was a significant positive correlation between ADAM17, EGFR, and Ki-67 with the stage of malignancy.

Abstract
Pancreatic cancer is among the deadliest malignancies; however, the genetic events that lead to pancreatic carcinogenesis in adults remain unclear. In vivo models in which these genetic alterations occur in adult animals may more accurately reflect the features of human cancer. In this study, we demonstrate that inactivation of Cdkn2b (p15ink4b) is necessary for induction of pancreatic cancer by oncogenic KRASG12D expression and inactivation of Tp53 and Cdkn2a in adult mouse pancreatic ductal cells (P60 or older). KRASG12D overexpression in these cells activated transforming growth factor-β signaling and expression of CDKN2B, which, along with CDKN2A, led to cellular senescence and protected cells from KRAS-mediated transformation via inhibition of retinoblastoma phosphorylation. These results show a critical role of CDKN2B inactivation in pancreatic carcinogenesis, and provide a useful adult animal model by genetic engineering via lentiviral delivery.

Abstract
Objective: To explore the interaction between family history of diabetes and hyperlipidemia on the risk of diabetes in population with normotension. Methods: A multistage stratified probability random sampling was conducted to select a representative sample of urban residents aged 20-74 years in Harbin. A total of 376 diabetes patients with normotension and 3 692 residents with normal blood pressure, normal fasting glucose, and normal 2 hours glucose from OGTT were surveyed. The interaction was evaluated by using crossover analysis and additive model. Results: Multivariate logistic regression analysis indicated that there was a possible additive interaction between family history of diabetes and hyperlipidemia on the risk of diabetes. The relative excess risk due to the interaction, the attributable proportion due to the interaction, and the synergy index were 1.97 (95%CI:-0.32-4.26), 0.30 (95%CI: 0.03-0.57), and 1.54 (95%CI: 0.96-2.47), respectively. There were significant combination effects between family history of diabetes and high both total cholesterol and triglyceride, isolated high total cholesterol, and isolated high triglyceride levels; the ORs were 10.55 (95%CI: 5.62-19.80), 7.81 (95%CI: 3.65-16.71) and 5.13 (95%CI: 3.22-8.16), respectively. Conclusion: There might be synergistic effect between family history of diabetes and hyperlipidemia on the risk of diabetes in population with normotension.

Abstract
Objective: To investigate the feature of repetitive nerve stimulation (RNS) in patients with amyotrophic lateral sclerosis (ALS) and correlation between RNS and clinical features and electromyography (EMG) findings of the corresponding muscle. Methods: Needle EMG and RNS were performed in 53 patients with ALS, who were recruited into Department of Neurology of Chinese PLA general hospital during April to December in 2016. Decrement of the compond muscle action potential (CMAP) in response to RNS of different nerves and stimulus frequencies was compared. The effects of gender, age of onset, disease duration, region of onset, ALS functional rating scale-revised (ALSFRS-R) and rate of disease progression (ΔFS) on the decrement were analyzed. Results: 49.1% of patients with ALS had decremental responses to low frequency RNS (LF-RNS) in accessory nerve, which was lower in ulnar nerve (4.3%) and common peroneal nerve (2.6%). Decremental responses of accessory nerve at 3 Hz were observed in 49.1% of patients with ALS, more frequent than 30.2% at 1 Hz. None of the patients had increased responses to high frequency RNS. Patients with upper-limb-onset, longer disease duration and lower ALSFRS-R tended to have more frequent decrement of CMAP in response to RNS. The decrement with LF-RNS of accessory nerve was in concert with neurogenic damage of sternocleidomastoid muscle with needle EMG (r=0.365, P=0.007). There were 3 patients who had decremental responses to LF-RNS in accessory nerve without clinical involvement and neurogenic damage of sternocleidomastoid muscle. Conclusions: There is significant decrement of CMAP in response to LF-RNS of accessory nerve in patients with ALS, which may reveal neuromuscular junction (NMJ) impairment. It may indicated a dying-back pattern of disease progression which derived from motor neuron terminal or NMJ to neuronal soma that some patients with ALS have decremental responses in RNS without clinical involvement and neurogenic damage of sternocleidomastoid muscle.
