Abstract
Objective: To evaluate the efficacy and safety of pembrolizumab plus nab-paclitaxel and platinum as first-line treatment in patients with recurrent or metastatic head and neck squamous-cell carcinoma (R/M HNSCC). Methods: This was a prospective, single-arm, open label, phase 2 clinical study enrolling patients at the Cancer Hospital of the Chinese Academy of Medical Sciences with R/M HNSCC treated with pembrolizumab plus nab-paclitaxel and cisplatin or carboplatin. After six cycles of treatment, patients received pembrolizumab as maintenance therapy until disease progression or intolerable toxicity or completion of 35 cycles of treatment. The primary endpoint was objective response rate, and secondary endpoints included overall survival, progression-free survival, and safety profile. Efficacy was evaluated according to the response evaluation criteria in solid tumors 1.1, survival analysis was performed using the Kaplan-Meier method, and adverse events were assessed using the America National Cancer Institute Common Terminology Criteria for Adverse Events 5.0. Results: A total of 30 patients with R/M HNSCC were enrolled from 23 April 2021 to 22 March 2023, including 28 males and 2 females, with a median age of 67 years. The median follow-up time was 14.5 months, the objective response rate was 70.0%, the disease control rate was 96.7%, and the median progression-free survival and overall survival of all patients were 11.6 months and 18.8 months, respectively. Median duration of response was up to 17.3 months. Grade≥3 treatment-related adverse events were leukopenia (26.7%), neutropenia (26.7%), peripheral neurotoxicity (3.3%), rash (3.3%), hyperalgesia (3.3%), and immune-related pneumonitis (3.3%). The most common immune-related adverse event was hypothyroidism (40.0%). Conclusion: Pembrolizumab combined with nab-paclitaxel and platinum shows encouraging antitumor activity accompanied with a manageable safety profile in untreated R/M HNSCC patients in China.

Abstract
Objective: To analyze and evaluate the expressions and clinical value of tuftelin (TUFT1) and Krüppel-like factor 5 (KLF5) in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) tissues. Method: KLF5 mRNA and TUFT1 mRNA transcriptional status in cancer and non-cancer groups were compared according to the Cancer Genome Atlas (TCGA) database. The differences and prognostic value between the groups were analyzed. Postoperative liver cancer and its paired pericancerous tissues, with the approval of the ethics committee, were collected to build tissue chips. The expression of KLF5 and TUFT1 and their intracellular localization were verified by immunohistochemistry. Tissue expression and clinicopathological characteristics were analyzed by immunoblotting. SPSS software was used to analyze the relationship between SPSS and patient prognosis. Results: The transcription level of TUFT1 or KLF5 mRNA was significantly higher in the HCC group than the non-cancer group (P < 0.001), according to TCGA data. Immunohistochemistry and Western blotting examination confirmed the overexpression of TUFT1 and KLF5 in human HCC tissues, which were mainly localized in the cytoplasm and cell membrane. The positivity rates of TUFT1 and KLF5 were 87.1% ( χ(2) = 18.563, P < 0.001) and 95.2% ( χ(2) = 96.435, P < 0.001) in HCC tissues, and both were significantly higher than those in the adjacent group. The expression intensity was higher in stage III-IV than stage I-II of the International Union Against Cancer standard (P < 0.01). The clinicopathological features showed that the abnormalities of the two were significantly related to HBV infection, tumor size, extrahepatic metastasis, TNM stage, and ascites. Univariate analysis was related to tumor size, HBV infection, and survival. Multivariate analysis was an independent prognostic factor for patients with HCC. Conclusion: TUFT1 and KLF5 may both be novel markers possessing clinical value in the diagnosis and prognosis of HBV-related HCC.

Abstract
Objective: To investigated the safety and efficacy of donor-derived CD19+ or sequential CD19+ CD22+ chimeric antigen receptor T-cell (CAR-T) therapy in patients with B-cell acute lymphoblastic leukemia (B-ALL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: The data of 22 patients with B-ALL who relapsed after allo-HSCT and who underwent donor-derived CAR-T therapy at the Zhujiang Hospital of Southern Medical University and the 920th Hospital of Joint Logistics Support Force of the People's Liberation Army of China from September 2015 to December 2022 were retrospectively analyzed. The primary endpoint was overall survival (OS), and the secondary endpoints were event-free survival (EFS), complete remission (CR) rate, and Grade 3-4 adverse events. Results: A total of 81.82% (n=18) of the 22 patients achieved minimal residual disease-negative CR after CAR-T infusion. The median follow-up time was 1037 (95% CI 546-1509) days, and the median OS and EFS were 287 (95% CI 132-441) days and 212 (95% CI 120-303) days, respectively. The 6-month OS and EFS rates were 67.90% (95% CI 48.30%-84.50%) and 58.70% (95% CI 37.92%-79.48%), respectively, and the 1-year OS and EFS rates were 41.10% (95% CI 19.15%-63.05%) and 34.30% (95% CI 13.92%-54.68%), respectively. Grade 1-2 cytokine release syndrome occurred in 36.36% (n=8) of the patients, and grade 3-4 occurred in 13.64% of the patients (n=3). Grade 2 and 4 graft-versus-host disease occurred in two patients. Conclusion: Donor-derived CAR-T therapy is safe and effective in patients with relapsed B-ALL after allo-HSCT.

Abstract
Sinulariolide (SC-1) is a natural product extracted from the cultured-type soft coral Sinularia flexibilis and possesses anti-inflammation, anti-proliferative, and anti-migratory in several types of cancer cells. However, the molecular pathway behind its effects on inflammation remains poorly understood. Since inflammatory cytokines such as TGFβ, TNFα, IL-1, IL-6, and IL-8 activate transcription factors such as Smads, NF-κB, STAT3, Snail, Twist, and Zeb that drive the epithelial-to-mesenchymal transition (EMT), in this study, we focus on the investigation in effects of SC-1 on TGFβ-induced interleukin-6 (IL-6) releases in an in vitro cell culture model. We showed that both intracellular IL-6 expression and secretion were stimulated by TGFβ and associated with strong upregulation of IL-6 mRNA and increased transcription in A549 cells. SC-1 blocked TGFβ-induced secretion of IL-6 while showing no effect on the induction of fibronectin and plasminogen activator inhibitor-1 genes, indicating that SC-1 interferes with only a subset of TGFβ activities. In addition, SC-1 inhibits TGFβ-induced IL-6 by suppressing p38 MAPK signaling and subsequently inhibits NF-κB and its nuclear translocation without affecting the canonical Smad pathway and receptor turnover. Overall, these data suggest that p38 may involve in the inhibition of SC-1 in IL-6 release, thus illustrating an inhibitory effect for SC-1 in the suppression of inflammation, EMT phenotype, and tumorigenesis.

Abstract
BACKGROUND We previously reported that miR-195 exerts neuroprotection by inhibiting Sema3A and cerebral miR-195 levels decreased with age, both of which urged us to explore the role of miR-195 and miR-195-regulated Sema3 family members in age-associated dementia. METHODS miR-195a KO mice were used to assess the effect of miR-195 on aging and cognitive functions. Sema3D was predicted as a miR-195 target by TargetScan and then verified by luciferase reporter assay, while effects of Sema3D and miR-195 on neural senescence were assessed by beta-galactosidase and dendritic spine density. Cerebral Sema3D was over-expressed by lentivirus and suppressed by si-RNA, and effects of over-expression of Sema3D and knockdown of miR-195 on cognitive functions were assessed by Morris Water Maze, Y-maze, and open field test. The effect of Sema3D on lifespan was assessed in Drosophila. Sema3D inhibitor was developed using homology modeling and virtual screening. One-way and two-way repeated measures ANOVA were applied to assess longitudinal data on mouse cognitive tests. RESULTS Cognitive impairment and reduced density of dendritic spine were observed in miR-195a knockout mice. Sema3D was identified to be a direct target of miR-195 and a possible contributor to age-associated neurodegeneration as Sema3D levels showed age-dependent increase in rodent brains. Injection of Sema3D-expressing lentivirus caused significant memory deficits while silencing hippocampal Sema3D improved cognition. Repeated injections of Sema3D-expressing lentivirus to elevate cerebral Sema3D for 10 weeks revealed a time-dependent decline of working memory. More importantly, analysis of the data on the Gene Expression Omnibus database showed that Sema3D levels were significantly higher in dementia patients than normal controls (p < 0.001). Over-expression of homolog Sema3D gene in the nervous system of Drosophila reduced locomotor activity and lifespan by 25%. Mechanistically, Sema3D might reduce stemness and number of neural stem cells and potentially disrupt neuronal autophagy. Rapamycin restored density of dendritic spines in the hippocampus from mice injected with Sema3D lentivirus. Our novel small molecule increased viability of Sema3D-treated neurons and might improve autophagy efficiency, which suggested Sema3D could be a potential drug target. Video Abstract CONCLUSION: Our results highlight the importance of Sema3D in age-associated dementia. Sema3D could be a novel drug target for dementia treatment.

Abstract
Aging is a crucial risk factor for common neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD). Limited options are available for the treatment of age-related, multiple pathogenic mechanism-contributed diseases that usually advance to irreversible conditions with severe neurological deficits and result in a heavy socioeconomic burden on patients, families, and society. A therapy that decelerates disease progression and reduces the socioeconomic burden stemming from these diseases is required. Glucagon-like peptide-1 receptor (GLP-1R) is an important class of medication for type 2 diabetes mellitus (T2DM). Through pancreatic effects, GLP-1R agonists can stimulate insulin secretion, increase β-cell proliferation, reduce β-cell apoptosis, and inhibit glucagon secretion in patients with T2DM. Currently, seven clinically approved GLP-1R agonists are used for T2DM: exenatide, liraglutide, lixisenatide, extended-release exenatide, albiglutide, dulaglutide, and semaglutide. Besides the pancreas, GLP-1Rs are also expressed in organs, such as the gastrointestinal tract, heart, lung, kidney, and brain, indicating their potential use in diseases other than T2DM. Emerging evidence reveals that GLP-1R agonists possess pleiotropic effects that enrich neurogenesis, diminish apoptosis, preclude neurons from oxidative stress, and reduce neuroinflammation in various neurological conditions. These favorable effects may also be employed in neurodegenerative diseases. Herein, we reviewed the recent progress, both in preclinical studies and clinical trials, regarding these clinically used GLP-1R agonists in aging-related neurodegenerative diseases, mainly AD and PD. We stress the pleiotropic characteristics of GLP-1R agonists as repurposing drugs to target multiple pathological mechanisms and for use in the future for these devastating neurodegenerative conditions.

Abstract
There exists a complex relationship between liver and thyroid hormones. Liver plays an important role in the activation, inactivation, transportation, and metabolism of thyroid hormones. At the same time, thyroid hormones also affect hepatocytes activity and liver metabolism, such as lipid and bilirubin metabolism. Importantly, thyroid hormone levels often change abnormally in patients with liver cirrhosis. Therefore, studying the change of thyroid hormone levels in patients with liver cirrhosis has a certain clinical value for assessing the severity, prognosis, diagnosis and treatment. This paper reviews the research progress on the relationship between liver cirrhosis and thyroid hormone.

Abstract
Objective: To investigate the relationship between plasma levels of complements before treatment and the clinicopathological feathers and prognoses of diffuse large B-cell lymphoma (DLBCL) patients treated with Rituximab (R)-CHOP or R-CHOP-like therapy. Methods: The clinicopathological data of 105 DLBCL patients treated in cancer Hospital of Chinese Academy of Medical Sciences from 2010 to 2016 were collected. The plasma samples from 105 DLBCL patients treated with R-CHOP or R-CHOP-like therapy and 80 healthy controls were used to detect 34 complement levels before treatment by utilizing antibody microarray. The relationship between plasma levels of complements and the clinicopathological feathers and prognosis of DLBCL patients were analyzed. Results: The signal values of C1QA and CR1L in patients with international prognostic index (IPI) scores of 3-5 were 1 261.43±138.9 and 2 214.69±98.58, respectively, higher than 950.79±80.19 and 984.67±121.79 in patients with IPI scores of 0~2 (both P<0.05). The levels of C1QA and CR1L in the non-complete response (CR) group were 1 165.43±98.56 and 2 263.13±145.63, respectively, higher than 914.70±100.77 and 1 821.34±84.68 in the CR group (both P<0.05). Cox regression analysis showed that elevated C1QA signal value was associated with poor progression-free survival (PFS) and poor overall survival (OS) (PFS: HR=2.063, 95%CI: 1.220-3.489, P=0.007; OS: HR=2.23, 95%CI: 1.036~4.798, P=0.040). After IPI correction by Cox multivariate model, the elevated C1QA signal value was still correlated with poor PFS (HR=1.765, 95%CI 1.034~3.013, P=0.037). Conclusions: The baseline plasma levels of C1QA and CR1L are correlated with IPI scores and therapeutic effects of DLBCL patients treated with R-CHOP. The baseline plasma level of C1QA has a certain predictive value for the prognostic evaluation of DLBCL.

Abstract
Methamphetamine (METH) is a highly addictive psychostimulant that causes significant health issues due to high prevalence of its illegal use. Chronic use of METH is associated with cognitive impairments in both human and animal studies, but the underlying mechanism remains unclear. METH-induced neuroinflammation is, potentially, one of the factors that causes cognitive impairments. Therefore, the present study aimed to assess whether melatonin could provide protection against inflammation, in a manner comparable to the anti-inflammatory agent, minocycline, with consequent improvements of METH-induced cognitive impairments and associated abnormalities in the mouse hippocampus. Results from the Morris water maze (MWM) test and the novel object recognition test (NORT) showed that melatonin given after METH injections could ameliorate both METH-induced spatial and recognition memory impairments. These memory impairments are associated with changes in the neuroinflammatory profiles, including IL-6, IL-1β, and TNF-α, both in the blood serum and hippocampus of adult mice. METH-treated mice also exhibited reactive astrocytes and activated microglia in the hippocampus. METH-induced activation of glial cells is associated with the activation of the TLR4/MyD88/NFκB signaling pathway. Moreover, melatonin administration led to recovery of these METH-induced markers to control levels. Thus, we conclude that melatonin could potentially be used as a cognitive enhancer and anti-inflammatory agent in the treatment of METH use disorder in humans.

Abstract
Objective: To investigate the effects and the mechanism of Shendansanjie capsules on angiogenesis of colitis associated cancer(CAC) mice. Methods: Azoxymethane and dextran sulfact sodium were used to construct a mice model with CAC. Ten mice were divided into the normal group, model group, Shendan Sanjie capsule group, MK-2206 group, and Shendan Sanjie capsule + IGF-1 group, respectively. Immunohistochemistry was used to detect the microvessel density (MVD) in the colon tissue of each group of mice. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the mRNA levels of basic fibroblast growth factor (bFGF) and angiopoietin 2 (Ang2) in colon tissue. Western blot was used to detect the expressions of Akt, p-Akt, vascular endothelial growth factor A (VEGFA), hypoxia-inducible factor-1α (HIF-1α). Results: The number of MVD in the colon tissue of mice in the model group, Shendan Sanjie capsule group, MK-2206 group, Shendan Sanjie capsule + IGF-1 group were 63.3±3.3, 36.6±2.3, 36.6±2.2, 50.3±2.5, significantly higher than 2.0±0.1 in the normal group (P<0.05). The number of MVD in Shendan Sanjie capsule group, MK-2206 group and Shendan Sanjie capsule+ IGF-1 group are lower than that in model group (P<0.05), while Shendan Sanjie capsule+ IGF-1 group is higher than Shendan Sanjie Capsule group (P<0.05). The relative expressions of bFGF mRNA in the colon cancer tissue of mice in the model group, Shendan Sanjie capsule group, MK-2206 group and Shendan Sanjie capsule+ IGF-1 group were 4.55±0.31, 2.46±0.37, 2.49±0.33, 3.34±0.21, respectively, and the relative mRNA expressions of Ang2 were 5.78±0.19, 2.21±0.14, 2.26±0.17 and 3.67±0.32, respectively, which were significantly higher than 1.01±0.05 and 0.99±0.07 in the normal group (P<0.05). The mRNA levels of bFGF and Ang2 in Shendan Sanjie capsule group, MK-2206 group and Shendan Sanjie capsule+ IGF-1 group were lower than those in the model group (P<0.05), while Shendan Sanjie capsule+ IGF-1 group is higher than Shendan Sanjie capsule group (P<0.05). The relative expression levels of p-Akt/Akt, VEGFA and HIF-1α in colon cancer tissues of the model group were 4.75±0.18, 4.64±0.22 and 4.84±0.12, respectively, which were significantly higher than 1.01±0.07, 0.95± 0.08 and 0.98±0.05 in the normal group (P<0.05). The relative expressions of p-Akt/Akt, VEGFA and HIF-1α in colon cancer tissues in the Shendan Sanjie capsule group were 2.24±0.22, 3.15±0.26 and 2.07±0.18, respectively, which were significantly lower than those in the model group (P<0.05). However, compared with the MK-2206 group, the difference was not statistically significant (P>0.05). The relative expression levels p-Akt/Akt, VEGFA and HIF-1α in colon cancer tissue of the Shendan Sanjie capsule+ IGF-1 group were 3.37±0.15, 4.02±0.11, 3.52±0.24, respectively, which were significantly higher than those in the Shendan Sanjie capsule group (P<0.05). Conclusion: Shendan Sanjie capsules may inhibit Akt/HIF-1α/VEGFA signaling pathway, and then reduce the expression of microvascular growth factors bFGF and Ang2, thereby inhibit the tumor angiogenesis of CAC.

Abstract
Objective: To analyze the expression of CD44 in non-alcoholic fatty liver disease (NAFLD) accompanied with hepatitis B virus (HBV) infection and its clinical significance. Methods: Blood sample of hospitalized patients with NAFLD, chronic hepatitis B, cirrhosis, and healthy population (control) was collected. The study was approved by the hospital ethics committee. Serum CD44 level and clinopathological characteristics were analyzed quantitatively by enzyme-linked immunosorbent-assay. Flow cytometry was used to analyze the proportion of CD44(+)T lymphocytes in patients with NAFLD and chronic hepatitis B. NAFLD model was prepared with high-fat diet to verify the abnormal expression of CD44. Results: Compared with the healthy control group, the expression of serum CD44 in the cirrhosis group, chronic hepatitis B group and NAFLD group was increased, and the difference between the groups were statistically significant (P < 0.01). NAFLD patients graded as mild or severe group were equally accompanied by hepatocyte injury, abnormal blood glucose, lipid or CD44. In NAFLD patients accompanied with HBV infection, serum CD44 concentrations were significantly higher in HBsAg, HBeAg and HBV DNA positive group than HBsAg, HBeAg and HBV DNA negative group (P < 0.01). The proportion of CD44(+)T lymphocytes in peripheral blood of NAFLD and chronic hepatitis B group were 78.2% ± 16.3% and 68.5% ± 20.9%, respectively, and both groups (NAFLD and chronic hepatitis B) were significantly higher than the healthy control group (46.5% ± 20.5%) (P < 0.05). The high-fat diet model confirmed that in rat liver tissues the CD44 was overexpressed with fat deposition accompanied with liver cell damage, especially remarkable in liver tissues containing carcinogens. Conclusion: The abnormal expression of CD44 in patients with NAFLD may be related to the malignant transformation of HBV-related liver disease.

Abstract
Chronic kidney disease (CKD) is characterized by the progressive loss of renal function; moreover, CKD progression commonly leads to multiple comorbidities, including neurological dysfunction and immune disorders. CKD-triggered neuroinflammation significantly contributes to cognitive impairment. This study aimed to investigate the contribution of uremic toxins to cognitive impairment. Serum creatinine, blood urea nitrogen (BUN), indoxyl sulfate (IS), and p-cresol sulfate (PCS) levels were measured using an enzyme-linked immunosorbent assay and high-performance liquid chromatography. The creatinine, BUN, IS, and PCS levels were increased from 4 weeks after 5/6-nephrectomy in mice, which suggested that 5/6-nephrectomy could yield a CKD animal model. Further, CKD mice showed significantly increased brain and serum indoxyl sulfate levels. Immunohistochemistry analysis revealed hippocampal inflammation and NLRP3-inflammasomes in astrocytes. Further, the Y-maze and Morris water maze tests revealed learning and memory defects in CKD mice. AST-120, which is also an IS absorbent, effectively reduced serum and hippocampal IS levels as well as reversed the cognitive impairment in CKD mice. Additionally, NLRP3-knockout mice that underwent 5/6-nephrectomy showed no change in cognitive function. These findings suggested that IS is an important uremic toxin that induces NLRP3 inflammasome-mediated not only in microglia, but it also occurred in astrocytic inflammation, which subsequently causes cognitive impairment.

Abstract
Pigeon racing's recent upturn in popularity can be attributed in part to the huge prize money involved in these competitions. As such, methods to select pigeons with desirable genetic characteristics for racing or for selective breeding have also been gaining more interest. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for genotyping-specific genes is one of the most commonly used molecular techniques, which can be costly, laborious and time consuming. The present study reports the development of an alternative genotyping method that employs Kompetitive Allele Specific Polymerase Chain Reaction (KASP) technology with specifically designed primers to detect previously reported racing performance-associated polymorphisms within the LDHA, MTYCB, and DRD4 genes. To validate, KASP assays and PCR-RFLP assays results from 107 samples genotyped for each of the genes were compared and the results showed perfect (100%) agreement of both methods. The developed KASP assays present an alternative rapid, reliable, and cost-effective method to identify polymorphisms in pigeons.

Abstract
Objective: To explore the value of Krüppel-like factor 5 (KLF5), a family member of the zinc finger protein transcription factor, in the diagnosis and prognostic evaluation of hepatocellular carcinoma (HCC). Methods: Cancerous and non-cancerous tissues were collected from 126 cases after HCC surgery by self-matching method with microarray fabrication. Immunohistochemistry was used to analyze the expression of KLF5, clinicopathological characteristics and prognostic value. The sera of 222 cases with chronic liver disease were collected and their KLF5 levels were quantitatively determined by enzyme-linked immunosorbent assay (ELISA). Simultaneously, 40 normal human sera were used as controls to evaluate the value of abnormal KLF5 in the diagnosis and differentiation of benign and malignant liver diseases. T-test, Z-test and χ (2) test were performed on the data. Results: The positive expression rate of KLF5 in the HCC group was 95.2% (120/126), which was significantly higher than the non-cancerous group 38.9% (49/126; χ (2) = 14.385, P < 0.001). KLF5 expression was significantly correlated with TNM stage (stage I 35%, stage II 40%, stage III 74.4%, stage IV 78.1%), tumor size, alpha fetoprotein (AFP) concentration, portal vein embolism, HBV infection and 5-year survival rate. Univariate/multivariate analysis showed that KLF5 high expression was an independent predictor of HCC prognosis. The serum KLF5 level was significantly higher in HCC patients than liver cirrhosis, chronic hepatitis and normal control group (P < 0.001). With the serum KLF5 > 800 ng/ml and AFP > 25 μg/L as limit, the positive rates for HCC diagnosis were 90.48% and 73.81%, respectively, which were lower than the AFP specificity and false positive rate, and was helpful for the differential diagnosis of benign and malignant liver diseases. Conclusion: The overexpression of KLF5 in liver cancer tissues and blood is closely related to the HCC clinical stage and prognosis. Moreover, KLF5 analysis is helpful for HCC diagnosis and differential diagnosis.

Abstract
Objective: To analyze the expression of tuftelin protein (TUFT1) and its clinical value in hepatocellular carcinoma (HCC)-related liver cancer tissues. Methods: The biological information data of TUFT1 mRNA expression in liver cancer and non-cancer tissues were analyzed from the TCGA and Oncomine database. After the approval of the ethics committee, the self-pairing method was used to collect the postoperative cancer and para-carcinoma tissues of 132 HCC cases hospitalized between January 2009 and December 2014. Tissue microarray and immunohistochemistry (IHC) were used to analyze the expression of TUFT1 in liver tissues. According to IHC staining, liver cancer was divided into high TUFT1 and low/no expression group. Combined with clinical data, the clinicopathological characteristics were statistically analyzed between and within the groups. The 5-year overall survival (OS) and disease-free survival (DFS) was analyzed by correlation analysis. Results: IHC staining showed that TUFT1 in cancer tissue was localized in the cytoplasm and cell membrane, and its positive expression rate was significantly higher in the liver cancer group (87.1%) than the para-carcinoma group (64.4%) (χ (2) = 18.563, P < 0.001). TUFT1 expression intensity in patients with liver cancer was significantly correlated with HBeAg positive (χ (2) = 4.080, P = 0.043), tumor size (χ (2) = 9.388, P = 0.002), vascular invasion (χ (2) = 14.885, P < 0.001), TNM stage (χ (2) = 13.516, P < 0.001) and ascites (χ (2) = 5.940, P = 0.015). TUFT1 high expression was negatively correlated with OS and DFS (P < 0.001). Conclusion: The overexpression of TUFT1 is closely related to HBV replication, vascular invasion and poor prognosis, and it is expected to become a useful marker for liver cancer diagnosis and prognosis.

Abstract
Immune checkpoint molecules, especially PD-1 and its ligand PD-L1, act as a major mechanism of cancer immune evasion. Although anti-PD-1/PD-L1 monotherapy increases therapeutic efficacy in melanoma treatment, only a subset of patients exhibits long-term tumor remission, and the underlying mechanism of resistance to PD-1/PD-L1 inhibitors remains unclear. In this study, we demonstrated that cell surface retention of PD-L1 is inversely correlated with PAI-1 expression in vitro, in vivo, and in clinical specimens. Moreover, extracellular PAI-1 induced the internalization of surface-expressed PD-L1 by triggering clathrin-mediated endocytosis. The endocytosed PD-L1 was transported to lysosomes for degradation by endolysosomal systems, resulting in the reduction of surface PD-L1. Notably, inhibition of PAI-1 by pharmacological inhibitor with tiplaxtinin led to elevated PD-L1 expression on the plasma membrane, both in vitro and in vivo. Strikingly, targeting PAI-1 by tiplaxtinin treatment synergizes with anti-PD-L1 immune checkpoint blockade therapy in a syngeneic murine model of melanoma. Our findings demonstrate a role for PAI-1 activity in immune checkpoint modulation by promoting surface PD-L1 for lysosomal degradation and provides an insight into the combination of PAI-1 inhibition and anti-PD-L1 immunotherapy as a promising therapeutic regimen for melanoma treatment.

Abstract
Objective: To explore the relationship between lipid indicators and the incidence of diabetes, and to compare the diabetes prediction and identification power of traditional lipid combined lipid indicators, in order to explore the best alternative indicators for identifying and predicting diabetes. Methods: Based on the Jinchang cohort, a nested case-control study was conducted in 1 025 new cases of diabetes after excluding patients with malignant tumor and related endocrine, circulatory system disease, then an age (±2 years), gender matched 1∶1 control group of 1 025 cases was set to analyze the relationship between the incidence of diabetes and lipid parameters. Results: Among the traditional lipid parameters, the fourth quartile of TG, TC, and LDL-C indicated higher risks of developing diabetes, which was 14.00 times (95%CI: 9.73-20.15), 2.15 times (95%CI: 1.65-2.79) and 1.66 times (95%CI: 1.29-2.14) than that of the first quartile, respectively. The risk of developing diabetes indicated by the fourth quartile of HDL-C was 0.21 times than that indicated by the first quartile (95%CI: 0.15-0.28). In the combined lipid parameters, the fourth quartile of TG/HDL-C, TC/HDL-C, LDL-C/HDL-C and non-HDL-C indicated higher risks of developing diabetes, which was 14.86 times (95%CI: 10.35-21.34), 8.12 times (95%CI: 5.94-11.01), 5.85 times (95%CI:4.34-7.88) and 5.20 times (95%CI: 3.85-7.03) than that indicated by the first quartile, respectively. The areas under the ROC curve of TG, TC, HDL-C, LDL-C, TG/HDL-C, TC/HDL-C, LDL-C/HDL-C and non-HDL-C were 0.76 (95%CI: 0.74-0.78), 0.59 (95%CI: 0.57-0.61), 0.67 (95%CI: 0.65-0.69), 0.57 (95%CI: 0.55-0.59), 0.77 (95%CI: 0.75-0.78), 0.73 (95%CI: 0.71-0.75), 0.69 (95%CI: 0.67-0.71) and 0.66 (95%CI: 0.64-0.68), respectively. The optimal diabetes predicting point cuts of TG, TC, HDL-C, LDL-C, TG/HDL-C, TC/HDL-C, LDL-C/HDL-C and non-HDL-C were 1.40, 4.70, 1.28, 3.25, 1.17, 3.43, 2.46, and 3.58 mmol/L, respectively. Conclusions: Lipid metabolic disorder is a risk factor for diabetes. TG and TG/HDL-C are the good lipid metabolism indicators for the prediction of diabetic.

Abstract
Objective: To explore the relationship of body mass index and blood pressure with the incidence of diabetes in Jinchang cohort. Methods: We designed a nested case-control study, a total of 29 572 workers who had no history of diabetes in baseline survey in Jinchang cohort were selected as the study cohort from June 2011 to December 2013. After 2 year follow-up, 1 021 workers with first diagnosed diabetes were selected as the case group, after 1∶1 matching according to the same gender and age ±2 years among those without diabetes, circulatory system, or endocrine system diseases during the same follow-up period, 1 021 controls was selected and 2 042 subjects were finally included. We used multivariate conditional logistic regression model, additive interaction model and multiplicative interaction model to explore the relationship of body mass index and blood pressure with the incidence of diabetes. Results: After adjusting for factors such as occupation, alcohol use, family history of diabetes, hyperuricemia, hypercholesterolemia, hypertriglyceridemia, low-HDL cholesterolemia and high-LDL cholesterolemia, multivariate conditional logistic regression analysis showed that the risk of diabetes increased with body mass index and blood pressure. Hypertension and overweight/obesity had a multiplicative interaction on the incidence of diabetes. The risks of diabetes in men and women with hypertension and overweight/obese were 2.04 times (95%CI: 1.54-2.69) and 3.88 times (95%CI: 2.55-5.91) higher than those in men and women with normal body weight and blood pressure, respectively. In the combination of BMI and blood pressure, obese individuals with SBP≥160 mmHg were 4.57 times (95%CI: 2.50-8.34) more likely to have diabetes than those with normal BMI and SBP, obese individuals with DBP≥90 mmHg were 3.40 times (95%CI: 2.19-5.28) more likely to have diabetes than those with normal BMI and DBP. Conclusions: Overweight/obesity and hypertension can increase the risk of diabetes. Health education about body weight and blood pressure controls should be strengthened to reduce the risk of diabetes.

Abstract
Objective: To investigate the relationship of triglyceride (TG), fasting blood glucose (FPG) and triglyceride glucose product index (TyG) with the incidence of hypertension, and provide basic data for the prevention and treatment of hypertension in the population. Methods: A total of 23 581 individuals who met the research criteria in Jinchang cohort were selected as the research subjects, the Cox proportional hazard model was used to analyze the relationship of TG, FPG, and TyG with the risk of hypertension. A stratified analysis was conducted by sex. Results: After adjusting for confounding factors, compared with the normal TG group, the HR(95%CI) of the elevated TG margin group and the elevated group were 1.16 (1.01-1.34) and 1.49 (1.30-1.70), respectively in the total population. Among men, they were 1.13 (1.01-1.27) and 1.17 (1.06-1.30), and among women, they were 1.05 (0.88-1.26) and 1.06 (0.88-1.28). Compared with the normal FPG group, the HR (95%CI) of the FPG-impaired group were 1.29 (1.13-1.48) in the total population, 1.26 (1.08-1.48) in men and 1.59 (1.14-2.21) in women. Taking the lowest quartile array as a reference, the HR (95%CI) of the highest quartile array of TyG was 1.73 (1.45-2.07) in the total population, 1.32 (1.14-1.53) in men and 1.87 (1.37-2.54) in women. TG, FPG had a nonlinear dose-response relationship with the risk of hypertension, while TyG had a linear correlation with the risk of hypertension. Conclusions: Higher TG, FPG, and TyG levels are independent risk factors for the incidence of hypertension. People with higher TG, FPG and TyG are at high risk for hypertension, to which close attention should be paid in the prevention and treatment of hypertension.

Abstract
Rationale: The major cause of heart failure is myocardium death consequent to detrimental cardiac remodeling and fibrosis following myocardial infarction. The cardiac protective cytokine interleukin (IL)-33, which signals by ST2 receptor binding, is associated with group 2 innate lymphoid cell (ILC2) activation and regulates tissue homeostasis and repair following tissue injury in various tissues. However, the distribution and role of IL-33-responsive ILC2s in cardiac fibrosis remain unclear. In this study, we elucidated the roles of IL-33-responsive cardiac-resident ILC2s and IL-33-mediated immunomodulatory functions in cardiac fibrosis. Methods: We examined the distribution of cardiac ILC2s by using flow cytometry. The roles of IL-33-mediated ILC2 expansion in cardiac fibrosis was evaluated in the mouse model of catecholamine-induced cardiac fibrosis. ILC-deficient Rag2‒/‒IL2Rγc‒/‒ mice were implemented to determine the contribution of endogenous ILC in the progression of cardiac fibrosis. Histopathological assessments, speckle tracking echocardiography, and transcriptome profile analysis were performed to determine the effects of IL-33-mediated cardiac protective functions. Results: We identified the resident cardiac ILC2s, which share similar cell surface marker and transcriptional factor expression characteristics as peripheral blood and lung tissue ILC2s. IL-33 treatment induced ILC2 expansion via ST2. In vivo, ILC-deficient Rag2‒/‒IL2Rγc‒/‒ mice developed exacerbated cardiac fibrosis following catecholamine-induced stress cardiac injury. IL-33 treatment expanded cardiac ILC2s and revealed protective effects against cardiac tissue damage with reduced cardiomyocyte death, immune cell infiltration, tissue fibrosis, and improved myocardial function. Transcriptome analysis revealed that IL-33 attenuated extracellular matrix synthesis- and fibroblast activation-associated gene expressions. IL13-knockout or epidermal growth factor receptor (EGFR) inhibition abolished IL-33-mediated cardiac protective function, confirming IL-13 and EGFR signaling as crucial for IL-33-mediated cardioprotective responses. Moreover, ILC2-produced BMP-7 served as a novel anti-fibrotic factor to inhibit TGF-β1-induced cardiac fibroblast activation. Conclusion: Our findings indicate the presence of IL-33-responsive ILC2s in cardiac tissue and that IL-33-mediated ILC2 expansion affords optimal cardioprotective function via ILC2-derived factors. IL-33-mediated immunomodulation is thus a promising strategy to promote tissue repair and alleviate cardiac fibrosis following acute cardiac injury.

Abstract
AIMS Methamphetamine (METH) has become a major public health problem because of its abuse and profound neurotoxic effects, causing alterations in brain structure and function, and impairing cognitive functions, including attention, decision making, emotional memory, and working memory. This study aimed to determine whether melatonin (MEL), the circadian-control hormone, which has roles beyond circadian rhythm regulation, could restore METH-induced cognitive and neuronal impairment. MAIN METHODS Mice were treated with either METH (1 mg/kg) or saline for 7 days, followed by MEL (10 mg/kg) or saline for another 14 days. The Morris water maze (MWM) test was performed one day after the last saline or MEL injection. The hippocampal neuronal density, synaptic density, and receptors involved in learning and memory, along with downstream signaling molecules (NMDA receptor subunits GluN2A, GluN2B, and CaMKII) were investigated by immunoblotting. KEY FINDINGS METH administration significantly extended escape latency in learning phase and reduced the number of target crossings in memory test-phase as well as decreased the expression of BDNF, NMDA receptors, TrkB receptors, CaMKII, βIII tubulin, and synaptophysin. MEL treatment significantly ameliorated METH-induced increased escape latency, decreased the number of target crossings and decreased expression of BDNF, NMDA receptors, TrkB receptors, CaMKII, βIII tubulin and synaptophysin. SIGNIFICANCE METH administration impairs learning and memory in mice, and MEL administration restores METH-induced neuronal impairments which is probably through the changes in BDNF, NMDA receptors, TrkB receptors, CaMKII, βIII tubulin and synaptophysin. Therefore, MEL is potentially an innovative and promising treatment for learning and memory impairment of humans.

Abstract
Objective: To investigate the intra-observer reproducibility of Ki-67 assessment in breast cancers using three methods based on digital slide. Methods: Thirty cases of invasive breast cancer tissues were immunostained for Ki-67 by automatic stainer, and then scanned into digital pathological slides. Ki-67 positive index was measured individually by three pathologists using size-set visual assessment of hot spot (SSVAHS), size-set semi-automatic counting of hot spot(SSSACHS), and size-set automatic counting of hot spot (SSACHS), respectively, and repeated for 10 times. Intraclass correlation coefficient (ICC) of each assessment method was calculated, and the intraobserver reliability was classified as excellent, good, fair and poor according to ICC. Results: The ICC by 3 pathologists using SSVAHS was 0.832, 0.843 and 0.826, respectively, The ICC using SSSACHS was 0.926,0.938,0.929, and the ICC using SSACHS was 0.964, 0.971 and 0.968.The intraobserver reliability level of all three methods was excellent. Conclusion: The three methods of Ki-67 assessment achieve satisfactory intraobserver reproducibility, and the order of reproducibility from high to low is SSACHS, SSSACHS, and SSVAHS.

Abstract
Simple Summary The study demonstrated that the treatment with GLP-1 of SH-SY5Y human neuroblastoma cells increased the expression of AMPA receptors, NMDA receptors, dopamine receptors, synaptic proteins-synapsin 1, synaptophysin, and postsynaptic density protein 95, but not muscular and nicotinic acetylcholine receptors. In addition, the biomarker of dividing neuronal cells, vimentin, was decreased after treatment with GLP-1. Tuj1 immunostaining images showed that GLP-1 induced neurite processes and the development of neuronal morphologies. The GLP-1-differentiated neurons were able to be induced to generate action potentials by single cell patch-clamp. Our results also suggested that the PI3K-AKT axis is the dominant signaling pathway promoting the differentiation of SH-SY5Y cells into mature and functional neurons in response to GLP-1 receptor activation. The sequential treatment of retinoic acid and GLP-1 within a serum-free medium is able to trigger the differentiation of SH-SY5Y cells into morphologically and physiologically mature glutamatergic and dopaminergic neurons. Abstract Background: Neurons are terminally-differentiated cells that generally develop from neuronal stem cells stimulated by various neurotrophic factors such as NGF, BDNF, NT3, and NT-4. Neurotrophic factors have multiple functions for neurons, including enabling neuronal development, growth, and protection. Glucagon-like peptide-1 (GLP-1) is an intestinal-secreted incretin that enhances cellular glucose up-take to decrease blood sugar levels. However, many studies suggest that the function of GLP-1 is not limited to the regulation of blood sugar levels. Instead, it may also act as a neurotrophic factor with a role in ensuring neuronal survival and neurite outgrowth, as well as protecting synaptic plasticity and memory formation. Methods: The SH-SY5Y cells were differentiated by sequential treatments of retinoic acid and GLP-1 treatment within polyethylenimine-coated dishes under serum-free Neurobasal medium. PI3K inhibitor (LY294002) and MEK inhibitor (U0126) were used to determine the signaling pathway in regulation of neuronal differentiation. Neuronal marker (TUJ1) and synaptic markers (synapsin 1, synaptophysin, and PSD95) as well as single cell patch-clamp were applied to determine maturity of neurons. Antibodies of AMPA receptor, NMDA receptor subunit 2A, dopamine receptor D1, muscarinic acetylcholine receptor 2, and nicotinic acetylcholine receptor α4 were used to examine the types of differentiated neurons. Results: Our study’s results demonstrated that the treatment with GLP-1 of SH-SY5Y human neuroblastoma cells increased the expression of AMPA receptors, NMDA receptors, dopamine receptors, synaptic proteins-synapsin 1, synaptophysin, and postsynaptic density protein 95, but not muscular and nicotinic acetylcholine receptors. In addition, the biomarker of dividing neuronal cells, vimentin, was decreased after treatment with GLP-1. Tuj1 immunostaining images showed that GLP-1 induced neurite processes and the development of neuronal morphologies. The GLP-1-differentiated neurons were able to be induced to generate action potentials by single cell patch-clamp. Our study also suggested that the PI3K-AKT axis is the dominant signaling pathway promoting the differentiation of SH-SY5Y cells into mature and functional neurons in response to GLP-1 receptor activation. Conclusions: The sequential treatment of retinoic acid and GLP-1 within a serum-free medium is able to trigger the differentiation of SH-SY5Y cells into morphologically and physiologically mature glutamatergic and dopaminergic neurons.

Abstract
Objective: To evaluate the clinical efficacy and safety of recombinant anti-HER2 humanized monoclonal antibody (Cipterbin) combined with vinorelbine in patients with HER2 positive metastatic breast cancer. Methods: Patients were randomized 2∶1 to test group and control group. Patients in test group received Cipterbin (4 mg/kg loading dose and 2 mg/kg maintenance dose each week, IV) combined with vinorelbine (25 mg/m(2) on days 1,8 and 15 of each 28 days, IV). Patients in control group received vinorelbine (25 mg/m(2) on days 1,8 and 15 of each 28 days, IV).The primary end point was progression free survival (PFS). Results: A total of 315 patients were enrolled from Jan 2009 to Jan 2013 (212 in test group and 103 in control group). The median PFS of test group was significantly longer than that of control group, 39.1 weeks vs 14.0 weeks (HR=0.24; 95%CI, 0.16-0.36; P<0.000 1). The objective response rate (ORR) and disease control rate (DCR) in test group were significantly higher than those in control group, ORR was 46.7% vs 18.45% (P<0.000 1) and DCR was 79.72% vs 45.63% (P<0.000 1). The incidence of neutropenia, leucopenia and erythrocytopenia were higher in both groups, but there was no significant difference between two groups.The most common adverse events associated with Cipterbin were infusion reactions. Left ventricular ejection fraction reduced to less than 50% in 5 patients, which were recovered. No serious cardiotoxicity. Conclusion: The recombinant anti-HER2 humanized monoclonal antibody (Cipterbin) combined with vinorelbine has significant efficacy and good safety. It is the optimized therapy regime for patients with taxane-pretreated HER2 positive metastatic breast cancer, which provides more targeted therapy opportunities for HER2 positive breast cancer patients in China.

Abstract
Objective: To share related knowledge and experiences with countries along the line, literature regarding current cohort studies was summarized. Distribution, establishment and development of cohort studies among large prospective general population were analyzed in 17 countries of Western Asia and the 16 countries of Central and Eastern Europe. Methods: Literature review was conducted to collect basic information on cohort studies, with descriptive study used to analyze the characteristics of these cohort studies. Results: There were 562 cohort studies with sample size as more than 1 000 stated in Western Asia and Central and Eastern Europe, including 468 (83.27%) carried out in the nation itself and 94 (16.73%) with international multicentered collaboration. According to the nature of cohort studies, 347 (61.74%) were etiologically based. As for the contents involved, 310 (55.16%) of them targeted on chronic/non-communicable diseases, 125 (22.24%) concentrated on maternal and child health. Among those on chronic/non-communicable diseases, 51 (16.45%) were on cancers and 83 (26.77%) on cardiovascular disease studies. There appeared 10 large prospective cohort studies targeting on general population, mainly ongoing in Iran and European countries, with a duration of 8-29 years, including 4 of them with sample size as more than 50 000. In terms of the contents, epidemiological investigation, physical examination and biological samples collection took the major parts. Few papers were published in 9 out of the 10 cohort studies at the early stage of those projects but the number of papers increased annually and stabilized to certain extent. Conclusions: The regional distribution of cohort studies carried out in countries from the Western Asia and Central and Eastern European areas appeared unbalanced. Contents of these designs would mainly involve etiological studies, with focus on non-communicable diseases as cancer, cardiovascular disease, diabetes, respiratory diseases, mental and psychological diseases, and maternal and infant health etc.. However, only few large prospective cohort studies would base on general population.

Abstract
Focal cortical dysplasia (FCD) is a congenital malformation of cortical development where the cortical neurons located in the brain area fail to migrate in the proper formation. Epilepsy, particularly medically refractory epilepsy, is the most common clinical presentation for all types of FCD. This study aimed to explore the expression change of circulating miRNAs in patients with FCD from serum exosomes. A total of nine patients with FCD and four healthy volunteers were enrolled in this study. The serum exosomes were isolated from the peripheral blood of the subjects. Transmission electron microscopy (TEM) was used to identify the exosomes. Both exosomal markers and neuronal markers were detected by Western blotting analysis to prove that we could obtain central nervous system-derived exosomes from the circulation. The expression profiles of circulating exosomal miRNAs were assessed using next-generation sequencing analysis (NGS). We obtained a total of 107 miRNAs with dominant fold change (>2-fold) from both the annotated 5p-arm and 3p-arm of 2780 mature miRNAs. Based on the integrated platform of HMDD v3.2, miRway DB and DIANA-miRPath v3.0 online tools, and confirmed by MiRBase analysis, four potentially predicted miRNAs from serum exosomes in patients with FCD were identified, including miR194-2-5p, miR15a-5p, miR-132-3p, and miR-145-5p. All four miRNAs presented upregulated expression in patients with FCD compared with controls. Through Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and pathway category of four target miRNAs, we found eight possible signaling pathways that may be related to FCD. Among them, we suggest that the mTOR signaling pathway, PI3K-Akt signaling pathway, p53 signaling pathway, and cell cycle regulation and TGF-beta signaling pathway are high-risk pathways that play a crucial role in the pathogenesis of FCD and refractory epilepsy. Our results suggest that the circulating miRNAs from exosomes may provide a potential biomarker for diagnostic, prognostic, and therapeutic adjuncts in patients with FCD and refractory epilepsy.

Abstract
Hepatocellular carcinoma (HCC) is a chronic inflammation derived from the background of hepatitis B and C virus (HBV and HCV) infection, chemical intoxicants, or non-alcoholic fatty liver disease. Cancerous liver cells can express and secrete a variety of relatively specific markers, such as carcinoembryonic type of alpha-fetoprotein (AFP), phosphatidylinositol-3 (Glypican-3, GPC-3), Wnt/β-Catenin key molecule of signaling pathway Wnt3a and liver cancer specific GGT-II (HS-GGT), etc. Clinical analysis of carcinoembryonic markers not only contributes to diagnosis and prognosis of HCC, but may also be the target of HCC immunotherapy with a promising prospect of development and application. This article reviews the latest valuable advances in carcinoembryonic type specific molecular markers and liver cancer immunotherapy.

Abstract
Objective: To investigate the clinical features, survival and prognostic factors of elder patients with diffuse large B-cell lymphoma (DLBCL). Methods: The clinical data of elder patients with diffuse large B-cell lymphoma enrolled in the Cancer Hospital of Chinese Academy of Medical Sciences from April 2006 to December 2012 were retrospectively collected. All the patients were divided into R-CHOP-like group and CHOP-like group according to the dosage regimen. And the differences in demographic characteristics, clinical features, survival time and prognostic factors were compared between these two groups. Results: A total of 158 patients were enrolled, of which 78 patients in the R-CHOP-like group and 80 patients in the CHOP-like group were eligible. There were no significant differences between two groups on age, gender, pathological staging, B symptoms, bulky mass, ECOG score, IPI score, pathological type, LDH level, β(2)-MG level, lymphocyte/monocyte ratio(LMR), neutrophils/lymphocyte ratio(NLR), platelet/lymphocyte ratio(PLR), Ki-67 index and bone marrow invasion. In the R-CHOP like group, the median progression-free survival (PFS) time was 10 months, and the median overall survival (OS) time was 30 months. The 1-year and 2-year PFS rates were 46.2% and 19.2%, respectively. The 1-, 2-, and 5-year OS rates were 79.5%, 59.0%, and 19.2%, respectively. In the CHOP-like group, the median PFS was 7 months, and the median OS was 15 months. The 1-year and 2-year PFS rates were 27.5% and 12.5% respectively. The 1-year, 2-year, and 5-year OS rates were 65.0%, 32.5% and 13.8%, respectively. The median PFS time and OS time in the R-CHOP group were significantly better than those in the CHOP group (P<0.05 for both). A stratified analysis showed that the PFS time and OS time were superior in the R-CHOP-like group compared to the CHOP-like group among patients older than 70 years (P<0.05 for both). In patients with stage Ⅲ-Ⅳ, the PFS time and OS time in the R-CHOP-like group were also superior to CHOP-like group (P<0.05 for both). Univariate Cox regression analysis showed that IPI score, LDH value, β(2)-MG value, ECOG score, LMR, and PLR had an significant effect on prognosis (P<0.05 for all). Multivariate Cox regression analysis showed that lymphocyte/monocyte ratio and platelet/lymphocyte ratio were independent prognostic factors for diffuse large B-cell lymphoma (P<0.05 for both). Conclusions: The R-CHOP-like chemotherapy regimen is superior to the CHOP-like regimen in the first-line treatment of patients with diffuse large B-cell lymphoma. ECOG score, LMR and PLR may be independent prognostic factors for diffuse large B-cell lymphoma. ECOG score, LMR and PLR are independent prognostic factors.

Abstract
Malignant peripheral nerve sheath tumor (MPNST) is a rare invasive soft tissue sarcoma that originates from peripheral nerve branches and peripheral nerve sheaths. Early radical surgery is an effective treatment for MPNST. Since it is insensitive to radiotherapy and chemotherapy, the disease manifests a rapid progression, poor prognosis and high mortality. In recent years, the translational researches on the driving factors and therapeutic targets of MPNST have been rapidly developed, including the pathways of NF1-Ras, Raf-MEK-ERK, PI3K-AKT-mTOR, Wnt signaling, and abnormal expressions of apoptotic proteins, the general loss of polycomb repressive complex 2 (PRC2), upregulation of the HDAC family, abnormal expressions of receptor tyrosine kinases, expressions of programmed cell death ligand (PD-L1), aurora kinase and various microRNAs.This review summarizes the current translational researches on potential therapeutic targets of MPNST, and the clinical trials which provide helpful information for MPNST targeted therapy.

Abstract
Low levels of reactive oxygen species (ROS) are critical for the operation of regular neuronal function. However, heightened oxidative stress with increased contents of oxidation markers in DNA, lipids, and proteins with compromised antioxidant capacity may play a harmful role in the brain and may be implicated in the pathophysiology of neurodegenerative diseases. Sestrins, a family of evolutionarily-conserved stress-inducible proteins, are actively regulated by assorted stresses, such as DNA damage, hypoxia, and oxidative stress. Three highly homologous genes that encode sestrin1, sestrin2, and sestrin3 proteins exist in the genomes of vertebrates. Under stressful conditions, sestrins are activated with versatile functions to cope with different types of stimuli. A growing body of evidence suggests that sestrins, especially sestrin2, can counteract oxidative stress, lessen mammalian/mechanistic target of rapamycin (mTOR) expression, and promote cell survival, thereby playing a critical role in aging-related disorders including neurodegeneration. Strategies capable of augmenting sestrin expression may; thus, facilitate cell adaptation to stressful conditions or environments through stimulation of antioxidant response and autophagy process, which may carry clinical significance in neurodegenerative diseases.

Abstract
Background Stroke is the second most common cause of deaths worldwide. After an ischemic stroke, the proliferated reactive astrocytes in the peri-infarct areas play a beneficial role in neuronal survival. As such, astrocytes have gradually become a target for neuroprotection in stroke. The present study assessed the hypothesis that Pinin (Pnn), originally identified as a nuclear and desmosome-associated protein and is now known to possess anti-apoptotic capacity, protects astrocytes from cell death after ischemic stroke and delineated the underlying mechanisms. Methods In in vivo experiments, adult male Sprague-Dawley rats (12-week old) were used to induce acute focal cerebral ischemia employing the middle cerebral artery occlusion (MCAO) method. In in vitro experiments, postnatal day 1 (P1) Sprague-Dawley rat pups were used to prepare cultures of primary astrocytes. Oxygen-glucose deprivation (OGD) and re-oxygenation (OGD/R) procedures were employed to mimic the hypoxic-ischemic condition of stroke in those astrocytes. Results We found in the peri-infarct area of the ipsilateral cortex and striatum in Sprague-Dawley rats after transient MCAO an increase in Pnn expression that correlated positively with the time-course of infarction as detected by T2-weighted imaging and triphenyltetrazolium chloride staining, augmented number of reactive astrocytes that double-labelled with Pnn as determined by immunofluorescence, and enhanced cytotoxic edema as revealed by diffusion weighted imaging; but mirrored the decreased cleaved caspase-3 as measured by western blot. In an OGD and OGD/R model using primary cultured astrocytes, treatment with Pnn siRNA doubled the chance of surviving astrocytes to manifest cell death as revealed by flow cytometry, and blunted activated ERK signaling, reduced Bcl-2 expression and augmented cleaved caspase 3 detected by western blot in the normoxia, OGD or OGD/R group. Gene-knockdown of Pnn also impeded the reversal from decline in cell viability, elevation in lactate dehydrogenase leakage and decrease in ATP production in the OGD/R group. Conclusion We conclude that the endogenous Pnn participates in neuroprotection after acute ischemic stroke by preserving the viability of astrocytes that survived the ischemic challenge via maintenance of mitochondrial anti-apoptotic and bioenergetics functions.

Abstract
Objective: To investigate the feasibility and value of interphase fluorescence in situ hybridization (FISH) in the pathological diagnosis, differential diagnosis and therapeutic assessment of B-cell lymphomas. Methods: The cohort included 604 cases of B-cell lymphoma which were collected at West China Hospital from May 2010 to December 2016.And all were subjected to interphase FISH using 11 break apart or fusion probes (MYC, bcl-2, bcl-6, IRF4, MYC/IgH, bcl-2/IgH, CCND1/IgH, IgH, API2/MALT1, p53/ATM, and D13S319/CEP12). Results: The median age of the 604 B-cell lymphoma patients was 47.7 (aged 2-90) years including 372 men and 232 women. All the cases was divided into 463 large B cell lymphomas(LBL) and 141 small B cell lymphomas, and the total interphase FISH positive rate was 59.8% (361/604). Among the 463 LBL, 12.5% (58/463), 9.5% (44/463) and 2.2% (10/463) of cases showed MYC, bcl-6 and bcl-2 gene rearrangements respectively; and 363 diffuse large B cell lymphoma (DLBCLs) were reclassified as germinal center B-cell (GCB) subtype (38.6%, 140/363) and non-GCB subtype (61.4%, 223/363) by Hans algorithm. The rearrangement rates in GCB and non-GCB DLBCL were 45.7%(64/140)and 21.5%(48/223; P=0.001), respectively. Compared to the non-GCB DLBCL, GCB DLBCL showed higher MYC and bcl-2 gene rearrangements (P=0.001). Eleven (2.4%, 11/463) cases had MYC and bcl-6 or bcl-2 gene rearrangement (double-hit lymphoma); one (0.2%, 1/463) case had MYC, bcl-6 and bcl-2 gene rearrangements (triple-hit lymphoma); two (0.4%, 2/463) cases had bcl-2 and bcl-6 gene rearrangements. MYC translocation and MYC/IgH fusion were detected in 94.2%(81/86) and 83.7%(72/86) cases of Burkitt lymphomas. IRF4 rearrangement was detected in two cases of IRF4+ LBCL. Genetic abnormalities were detected in 9/19, 100%(29/29), 30.8%(12/39) and 68.5%(37/54) cases of follicular lymphoma, mantle cell lymphoma, MALT lymphoma and chronic lymphocytic leukemia, respectively. Conclusions: Interphase FISH can rapidly and accurately detect the genetic changes in B-cell lymphomas. Different genetic changes are specifically valuable to the diagnosis, differential diagnosis, prognosis evaluation and treatment guidance of various B-cell lymphomas.

Abstract
Objective: Adenosquamous carcinoma of lung is an uncommon subtype with more aggressive behavior and poor prognosis than adenocarcinoma and squamous cell carcinoma. This study was aimed to investigate the clinicopathological characteristics and prognostic factors of lung adenosquamous carcinoma. Methods: The pathological features and follow-up data of 133 patients were collected and the prognostic factors of these patients were retrospectively analyzed. Results: Among the 133 patients, 81 cases (60.9%) smoked. Among the 62 patients whose percentage of histological components were identified, 45 cases had >50% adenocarcinoma components, and 17 cases had >50% squamous cell carcinoma components. 55 patients had lymph node metastasis at the first visit. All patients accepted at least one test of tumor driven gene mutation, and the results showed that the mutation rate of EGFR was 50.8% (67/132), the mutation rate of K-ras was 8.6% (11/128), the ALK-positive rate was 4.2% (2/48). The gender, smoking status, and the proportion of pathological components were the main influence factors of EGFR mutation status. The median overall survival was 28 months, the rates of 1-year, 3-year, and 5-year survival were 72.9%, 23.3%, and 9.0%, respectively. EGFR tyrosine kinase inhibitors (TKIs) treatment was an independent risk factor for prognose of these patients (P=0.024). Conclusions: Lung adenosquamous carcinoma is a rare subtype with high malignancy and poor prognosis. Early diagnosis and driven-mutation-based individualized therapy may improve the survival of patients with lung adenosquamous carcinoma.

Abstract
Background: Dehydration is common among ischemic stroke patients and is associated with early neurological deterioration and poor outcome. This study aimed to test the hypothesis that dehydration status is associated with decreased cerebral perfusion and aggravation of ischemic brain injury. Methods: Diffusion-weighted imaging and arterial spin labeling perfusion MR imaging were performed on rats with middle cerebral artery occlusion (MCAO) by using a 9.4T MR imaging scanner to measure the volume of infarction and relative cerebral blood flow (rCBF) after infarction. Twenty-five rats were assigned to either a dehydration group or normal hydration group, and dehydration status was achieved by water deprivation for 48 h prior to MCAO. Results: The volume of the infarction was significantly larger for the dehydration group at the 4th h after MCAO (p = 0.040). The progression in the infarct volume between the 1st and 4th h was also larger in the dehydration group (p = 0.021). The average rCBF values of the contralateral normal hemispheres at the 1st and the 4th h were significantly lower in the dehydration group (p = 0.027 and 0.040, respectively). Conclusions: Our findings suggested that dehydration status is associated with the progression of infarct volume and decreases in cerebral blood flow during the acute stage of ischemic stroke. This preliminary study provided an imaging clue that more intensive hydration therapies and reperfusion strategies are necessary for the management of acute ischemic stroke patients with dehydration status.

Abstract
High levels of serum free fatty acids (FFAs) and proteinuria have been implicated in the pathogenesis of obesity-related nephropathy. CD36, a class B scavenger receptor, is highly expressed in the renal proximal tubules and mediates FFA uptake. It is not clear whether FFA- and proteinuria-mediated CD36 activation coordinates NLRP3 inflammasomes to induce renal tubular injury and inflammation. In this study, we investigated the roles of CD36 and NLRP3 inflammasomes in FFA-induced renal injury in high-fat diet (HFD)-induced obesity. HFD-fed C57BL/6 mice and palmitate-treated HK2 renal tubular cells were used as in vivo and in vitro models. Immunohistochemical staining showed that CD36, IL-1β, and IL-18 levels increased progressively in the kidneys of HFD-fed mice. Sulfo- N-succinimidyl oleate (SSO), a CD36 inhibitor, attenuated the HFD-induced upregulation of NLRP3, IL-1β, and IL-18 and suppressed the colocalization of NLRP3 and ASC in renal tubular cells. In vitro, SSO abolished the palmitate-induced activation of IL-1β, IL-18, and caspase-1 in HK2 proximal tubular cells. Furthermore, treatment with SSO and the knockdown of caspase-1 expression by siRNA both inhibited palmitate-induced cell death and apoptosis in HK2 cells. Collectively, palmitate causes renal tubular inflammation, cell death, and apoptosis via the CD36/NLRP3/caspase-1 axis, which may explain, at least in part, the mechanism underlying FFA-related renal tubular injury. The blockade of CD36-induced cellular processes is therefore a promising strategy for treating obesity-related nephropathy.

Abstract
Objective: To analyze the clinical characteristics and prognosis of newly diagnosed localized head and neck rhabdomyosarcoma. Methods: Cases of newly diagnosed localized head and neck rhabdomyosarcoma between January 2006 and December 2016 were analyzed retrospectively. The clinical features of the patients were described. The Kaplan-Meier method was used to analyze the survival rate under different combined modality therapy and the survival rate with or without chemotherapy. The prognostic factors were analyzed by Cox model. Results: A total of 46 patients were included in this study. Among them, the median follow-up time was 77 months and the median relapse free survival time was 13 months. The relapse free survival time of 5 cases with inadequate local treatment and without combined chemotherapy was 5 months as control, and it was 7 months (P=0.110) in 11 cases with adequate local treatment without combined chemotherapy. Then in 7 cases with inadequate local treatment combined with chemotherapy and 23 cases with adequate local treatment combined with chemotherapy, it was 13 months (P=0.007) and 21 months (P<0.001), respectively. The median relapse-free survival time of chemotherapy patients was significantly longer than that of those without chemotherapy (21 vs 6 months, P=0.018). The effect of combined modality therapy was evaluated according to the adequacy of local treatment and whether to receive systemic chemotherapy, and the combined modality therapy degree was the independent prognostic factor in Cox's proportional hazards regression model (P=0.004). Conclusions: Rhabdomyosarcoma in head and neck is a highly malignant tumor with high relapse rate and easy metastasis. In patients with tolerable condition, systemic chemotherapy and adequate combined modality therapy are recommended to improve relapse-free survival.

Abstract
Interleukin (IL)-33, a member of the IL-1 family of cytokines, is involved in innate and adaptive immune responses via interaction with its receptor, ST2. Activation of ST2 signalling by IL-33 triggers pleiotropic immune functions in multiple ST2-expressing immune cells, including macrophages, neutrophils, eosinophils, basophils, mast cells, type 2 helper T cells, regulatory T cells, and group 2 innate lymphoid cells. IL-33-mediated effector functions contribute to the tissue inflammatory and reparative responses in various organs including lung, skin, kidney, central nerve system, cardiovascular system, and gastrointestinal system. Endogenous IL-33/ ST2 signaling exhibits diverse immune regulatory functions during progression of different diseases. IL-33 likely functions as a disease sensitizer and plays pathological roles in inflamed tissues in allergic disorders that involve hyperreactive immune responses in the context of skin and pulmonary allergy. However, IL-33 also mediates tissue-protective functions during the recovery phase following tissue injury in the central nerve system and gastrointestinal system. Modulation of the IL-33/ST2 axis, therefore, represents a promising strategy for treating immune disorders that involve dysregulation of the cytokine signalling. In the past two decades, therapeutic strategies blocking IL-33/ST2 have been extensively studied for the treatment of diseases in animal models. In this review, the current progress on the development of therapeutic biologics for targeting IL-33/ST2 signalling in inflammatory diseases is summarized.

Abstract
Sonic hedgehog (Shh), a member of the hedgehog (Hh) family, was originally recognized as a morphogen possessing critical characters for neural development during embryogenesis. Recently, however, Shh has emerged as an important modulator in adult neural tissues through different mechanisms such as neurogenesis, anti-oxidation, anti-inflammation, and autophagy. Therefore, Shh may potentially have clinical application in neurodegenerative diseases and brain injuries. In this article, we present some examples, including ours, to show different aspects of Shh signaling and how Shh agonists or mimetics are used to alter the neuronal fates in various disease models, both in vitro and in vivo. Other potential mechanisms that are discussed include alteration of mitochondrial function and anti-aging effect; both are critical for age-related neurodegenerative diseases. A thorough understanding of the protective mechanisms elicited by Shh may provide a rationale to design innovative therapeutic regimens for various neurodegenerative diseases.

Abstract
Objective: Primary gastric diffuse large B-cell lymphoma (PG-DLBCL) is the most common non-Hodgkin lymphoma (NHL) of extranodal origin. Most patients with PG-DLBCL had localized disease (stage Ⅰ or Ⅱ) at presentation, and will achieve complete response (CR) after induction chemotherapy. However, there has been little consensus regarding whether optimal treatment is provided by chemotherapy alone or chemotherapy plus radiotherapy, nor the treatment outcome from the addition of rituximab in localized-stage PG-DLBCL. Methods: Patients with Stage ⅠE and ⅡE PG-DLBCL were retrospectively analyzed. Patients have not undergone surgery, have received at least 3 cycles of R-CHOP or CHOP-like chemotherapy as initial therapy, and achieved CR or partial response (PR) were enrolled. Results: A total of 91 patients were studied. The median age was 51 years, included 47 males and 44 females. Fifty-two patients were at Stage ⅠE and 39 at Stage ⅡE, 64 (70.3%) patients received R-CHOP-like regimens, and 27 (29.7%) received CHOP-like regimens, the median chemotherapy cycle was 6 (3-8). Among the 91 patients, 80 (87.9%) patients achieved CR from induction chemotherapy, 11(12.1%) was evaluated PR. Of CR patients, 48 patients (60%) underwent consolidating radiotherapy and 32 patients (40%) did not receive radiotherapy; all PR patients received salvage radiotherapy. CR patients with and without radiation therapy had 4-year progression-free survival (PFS) rates of 96.4% and 96.7%, respectively (χ(2) = 0.546, P=0.46); 7/11 (63.6%) PR patients achieved CR after radiotherapy, with a median follow-up of 41 months, they were all disease free. For patients treated with R-CHOP or CHOP-like regimens, the 4-year PFS was 93.2% and 89.7%, respectively (χ(2)=0.096, P=0.757). Conclusions: Consolidation radiotherapy failed to improve the outcome for early-stage PG-DLBCL, while for PR patients, salvage radiotherapy increased CR rate and improved survival. The addition of rituximab to CHOP did not improve the efficacy.

Abstract
Objective: The clinical features and prognosis of diffuse large B-cell lymphoma (DLBCL) were analyzed to optimize the treatment. Methods: We retrospectively collected the clinical data of patients with advanced-stage DLBCL from January 2006 to December 2012 in National Cancer Center/Cancer Hospital. The demographic characteristics, clinical stage, histological diagnosis, treatment and prognostic characteristics of these patients were analyzed. Results: A total of 370 patients with median age of 55 years old were recruited in the study. The male-to-female ratio was 1.3∶1. Among the 361 patients who underwent therapy, 280 cases received chemotherapy alone, 65 cases received chemoradiotherapy, and 16 cases received chemotherapy combined with autologous hematopoietic stem cell transplantation (AHSCT). The median follow-up period was 89 months, the 5-year overall survival (OS) rate of the entire cohort was 42.9%. The 5-year OS rate of chemotherapy alone, chemoradiotherapy and chemotherapy combined with AHSCT were 36.8%, 58.5%, 87.5%, respectively. The 5-year OS rate were significantly different between chemoradiotherapy and chemotherapy alone (P=0.001), and between chemotherapy combined with AHSCT and chemoradiotherapy (P=0.040). Univariate analysis showed that the age, Eastern Cooperative Oncology Group performance status (ECOG PS) score, Ann Arbor stage, B symptom, bulky disease, number of extranodal sites, Ki-67 index, lactate dehydrogenase (LDH), β2-microglobulin (β2-MG), international prognostic index (IPI), therapeutic manner and chemotherapy combined with rituximab were significantly associated with the prognosis of advanced DLBCL patients (all P<0.05). Multivariate analysis demonstrated that the age >60 years, Ann Arbor stage IV, with B symptom, with bulky disease, ECOG PS≥1, Ki-67 index > 90%, CD5 expression, up-regulation of serum LDH and β2-MG, and chemotherapy without rituximab were related with the poor prognosis of patients with advanced-stage DLBCL (all P<0.05). Conclusions: Chemotherapy combined with rituximab can improve the outcome of patients with advanced-stage DLBCL. The age, stage, B symptom, bulky disease, ECOG PS score, Ki-67 index, CD5 expression, LDH, β2-MG and chemotherapy combined with rituximab are associated with the prognosis of these patients.

Abstract
Objective: To explore the prognostic significance of inflammatory indicator, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR), for advanced-stage diffuse large B-cell lymphoma (DLBCL). Methods: The data of advanced stage DLBCL cases was retrospectively collected, and all the patients were seen from January 2006 to December 2012 in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences. The patients were divided into the low NLR group (≤5∶1) and the high NLR group (>5∶1); the low PLR group (≤300∶1) and the high PLR group (>300∶1). Kaplan-Meier method was used to compare the survival rates between groups, multivriate Cox proportional hazard regression analysis was performed to assess the independent prognostic significance of clinical and histopathological variables on events or OS. Results: A total of 361 patients were included in the study. Under a median follow-up of 89 months, the 5-year overall survival (OS) and progression-free survival (PFS) of the whole group were 42.9% and 31.3%, respectively. The 5-year OS rate and PFS rate were 48.2% and 35.1% in the low NLR group, which were 24.1% and 17.7% in the high NLR group, respectively. The 5-year OS rates and PFS rate were 45.4% and 33.2% in the low PLR group, which were 29.8% and 21.1% in the high PLR group (all P<0.05). Univariate analysis showed that NLR >5∶1, PLR >300∶1, age>60 year, ECOG PS>1 score, stage Ⅳ, B symptom, bulky disease, number of extranodal sites >1, Ki-67index >90%, LDH elevated and β2-MG elevated had significant influence on prognosis(all P<0.05). Multivariate analysis demonstrated that NLR, stage, B symptom, bulky disease, ECOG PS score, Ki-67 index and β2-MG were associated with poor prognosis in the advanced-stage DLBCL. Conclusions: NLR was simple and feasible biomarker for prognosis of advanced-stage DLBCL patients.

Abstract
The monolayered intrarenal urothelium covers the renal papilla and ureteropelvic junction (UPJ). In response to increased renal pressure during obstruction or ischemic injuries, intrarenal urothelial cells begin to proliferate and form a multilayered urothelium. Little is known regarding the mechanism and pathophysiological role of urothelium hyperplasia during renal obstruction. In this study, we investigated the expression of interleukin (IL)-33, an IL-1 family cytokine, in kidneys with unilateral ureteral obstruction (UUO)-induced obstructive injury. IL-33 levels in hydronephrotic urine and serum were upregulated 2 days after UUO. The number of ST2-expressing immune cells was increased in the UUO kidney. We found that IL-33 was upregulated in vimentin-positive cells in the cortical and medullar layers and the UPJ stroma. Moreover, IL-33 expression was predominantly induced in multilayered keratin 5-positive urothelial cells in the UPJ. IL-33 was not detected in terminally differentiated superficial umbrella cells expressing uroplakin 3a. In vivo, we confirmed that deficiency of IL33 or its receptor ST2 attenuated UUO-induced hyperplasia of the UPJ urothelium. Deficiency of IL33 attenuated the expression of UUO-induced type 2 inflammatory cytokines and upregulated uroplakins and urothelial differentiation signaling in UPJ tissues. Our results collectively suggest that the IL-33/ST2 axis mediates the activation of innate immune responses and contributes to urothelial hyperplasia by regulating urothelial differentiation in obstructive kidney injury.

Abstract
Stroke is the leading cause of adult disability and mortality in most developing and developed countries. The current best practices for patients with acute ischemic stroke include intravenous tissue plasminogen activator and endovascular thrombectomy for large-vessel occlusion to improve clinical outcomes. However, only a limited portion of patients receive thrombolytic therapy or endovascular treatment because the therapeutic time window after ischemic stroke is narrow. To address the current shortage of stroke management approaches, it is critical to identify new potential therapeutic targets. The mitochondrion is an often overlooked target for the clinical treatment of stroke. Early studies of mitochondria focused on their bioenergetic role; however, these organelles are now known to be important in a wide range of cellular functions and signaling events. This review aims to summarize the current knowledge on the mitochondrial molecular mechanisms underlying cerebral ischemia and involved in reactive oxygen species generation and scavenging, electron transport chain dysfunction, apoptosis, mitochondrial dynamics and biogenesis, and inflammation. A better understanding of the roles of mitochondria in ischemia-related neuronal death and protection may provide a rationale for the development of innovative therapeutic regimens for ischemic stroke and other stroke syndromes. Review of current treatment of ischemic stroke indicates deficiency in the contemporary methods. Discuss the mitochondrial ROS-related signaling that affect neuronal fate after ischemic stroke. Mechanisms of mitochondrial dynamics and mitophagy could be pivotal for ischemic stroke. Inhibiting mitochondrion-induced inflammatory response is a potential treatment for ischemic stroke.

Abstract
Glucagon-like peptide-1 (GLP-1) is originally found as a metabolic hormone (incretin) that is able to regulate blood-glucose levels via promoting synthesis and secretion of insulin. GLP-1 and many analogues are approved for treatment of type II diabetes. Accumulating results imply that GLP-1 performs multiple functions in various tissues and organs beyond regulation of blood-glucose. The neuroprotective function of GLP-1 has been extensively explored during the past two decades. Three of our previous studies have shown that apurinic/apyrimidinic endonuclease 1 (APE1) is the only protein of the base excision repair (BER) pathway able to be regulated by oxidative stress or exogenous stimulations in rat primary cortical neurons. In this article, we review the role of APE1 in neurodegenerative diseases and its relationship to neuroprotective mechanisms of the activated GLP-1 receptor (GLP-1R) in neurodegenerative disorders. The purpose of this article is to provide new insight, from the aspect of DNA damage and repair, for studying potential treatments in neurodegenerative diseases.

Abstract
Objective: To improve the diagnostic accuracy of transthoracic echocardiography (TTE) by analyzing its limitations in diagnosing partial anomalous pulmonary venous drainage (PAPVD). Method: This was a retrospective analysis of PAPVD patients seen at the Children's Hospital of Fudan University from October 1 2006 to October 1 2016. The echocardiographic data were compared to findings on multi-slice spiral CT (MSCT), cardiac catheterization or surgery. The echocardiography machines used were Philip IE33, GE Vivid 7 and Vivid i with frequency ranging from 5.0 MHz to 7.5 MHz. The cardiac structure was analyzed according to Van Praagh segments. Result: A total of 43 cases of PAPVD were enrolled, male∶ female ratio 20∶23 with average age (27.9±21.4) months. Among them, 3 cases were simple PAPVD and 40 cases had other associated congenital heart diseases. TTE was successful in diagnosing 29 cases (67%) while 14 cases were missed. The diagnostic rate for right pulmonary vein drainage into superior vena cava, right atrium, inferior vena cava were 5/10, 17/20, and 3/5 respectively while left pulmonary vein drainage into left innominate vein was only 1/4. Added TTE images to re-exam the 9 of the 14 missed cases, 5 cases of abnormal drainage from right superior pulmonary vein were diagnosed, while 4 cases of drainage from right lower or left pulmonary vein were only picked up by indirect signs. Conclusion: The distance of the pulmonary veins from the routine ultrasound view and the possibility of branch number variation may limit the accuracy of TTE in diagnosing PAPVD, especially for drainage from right lower and left pulmonary vein. But TTE is still the preferred diagnostic method. The diagnostic rate could be increased by paying special attention to non-routine views including the suprasternal fossa, the right parasternal and subcostal area.

OBJECTIVE To investigate the mutation status of epidermal growth factor receptor (EGFR) and KRAS gene in patients with non-small cell lung cancer (NSCLC) in Xuanwei, Yunnan and to correlate the mutation status with clinicopathologic features. METHODS Mutation status of exons 18, 19, 20 and 21 of EGFR, and codons 12, 13 of KRAS in 63 cases of NSCLC were analyzed by gene sequencing and ARMS-Taqman probe method. Correlation with patients' clinicopathological characteristics was performed. RESULTS EGFR and KRAS mutations were present in 55.6% (35/63) and 6.3% (4/63), respectively. EGFR gene mutations were present, including exon 18 G719X in 14.3% (5/35), exon 19 in 14.3% (5/35), exon 20 S768I and T790M in 20.0% (7/35), exon 21 L858R in 31.4% (11/35), exon 18 G719X and exon 20 S768I double mutation in 17.1% (6/35), and exon 20 T790M and exon 21 L858R double mutation in 2.9% (1/35). KRAS mutations were seen in codon 12 in 3 of 4 cases, and codon 13 in 1 of 4 cases. EGFR mutations were mutually exclusive with KRAS mutations. According to statistic analysis, EGFR mutations were associated with the histological types of NSCLC(P<0.05), but without correlation with patient's gender, age, smoking status and lymph node metastasis(P>0.05). KRAS mutations in NSCLC had no correlation with the clinical pathologic characteristics of the patients. CONCLUSIONS A higher frequency of EGFR exon 18 G719X and 20 exon S768I mutations are found in the patients in Xuanwei, Yunnan. EGFR mutations are associated with histologic types of NSCLC, but without correlation with patient's gender, age, smoking status and lymph node metastasis. KRAS mutation in NSCLC has no correlation with the clinicopathologic characteristics of the patients.

Abstract
Ras mutations and overexpression of the Ras protein, p21Ras, are main causes of cancer development and progression, which has made the Ras gene and p21Ras important targets for therapy of Ras-driven cancers. We previously prepared recombinant adenovirus KGHV100 based on replication-defective adenovirus type 5, which could intracellularly express anti-p21Ras single chain fragment viable antibodies (scFv) and repress tumor growth in vitro and in vivo. However, the anti-tumor effects of this anti-p21Ras scFv were limited by short-term scFv expression due to a replication defect of KGHV100. To enhance the anti-tumor efficacy and safety of anti-p21Ras scFv, the present study constructed a dual-promoter-regulated recombinant adenovirus KGHV300 that carried anti-p21Ras scFv. In KGHV300, the expression levels of the essential replication genes E1a and E1b, were controlled by the human telomerase reverse transcriptase promoter and the hypoxia response element, respectively, and the anti-p21Ras scFv gene was controlled by the cytomegalovirus promoter. The conditional replication of KGHV300 and its antitumor efficacy were characterized in several tumor cell lines in vitro and in xenograft models of human breast cancer in nude mice. TCID50 assay demonstrated that KGHV300 could replicate in tumor cell lines but not in normal cell lines. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay indicated that the growth of tumor cells was effectively inhibited by KGHV300 infection. In MDA-MB-231 tumor xenograft models, KGHV300 effectively and significantly inhibited tumor growth and induced apoptosis of tumor cells. We concluded that the recombinant adenovirus KGHV300 may be a more potent and safer antitumor therapeutic for Ras-driven cancer biotherapy.

Abstract
To understand the potential functions of Wnt7b in different developmental stages and adult tissues of the mussel Mytilus coruscus, the Wnt7b gene was cloned using the rapid amplification of cDNA ends technique. The full-length Wnt7b gene was 1910 bp long, with a 1059-bp open reading frame encoding 352 amino acids. The amino acid sequence of the M. coruscus Wnt7b gene shared high homology with that of Homo sapiens (59%), Mus musculus (61%), Danio rerio (61% similarity), Biomphalaria glabrata (62% similarity), Aplysia californica (66% similarity), and Crassostrea gigas (74%). Wnt7b mRNA expression was detected by reverse transcription PCR in all tissues studied (mantle, adductor muscle, gill, foot, digestive gland, and male and female gonads), with the highest expression found in the gill, and in the male and female gonads. This indicates that Wnt7b may play an important role in gonadal maturation and in the functions of gills in the mussel M. coruscus. Expression of the Wnt7b gene during larval development stages, including the trochophore, D-shaped veliger, umbo veliger, pediveliger, and juvenile stages, was also detected. Wnt7b mRNA was highly expressed in the D-shaped veliger, umbo veliger, and pediveliger larvae stages, suggesting that Wnt7b may participate in larval development and in the process of metamorphosis in the mussel M. coruscus. Taken together, these findings provide new insights into the functions of the Wnt gene family during mussel larval development and settlement and metamorphosis.
