Abstract
BACKGROUND Empathy is a critical component of nursing care, impacting both nurses' and patients' outcomes. However, perceived empathy from spouses during pregnancy and its impact on health-related quality of life (HRQoL) are unclear. This study aimed to examine pregnant women's perceived empathy from their spouses and assess the relation of perceived empathy on HRQoL. METHODS This cross-sectional study, performed in the obstetric clinics or wards of four well-known hospitals in Anhui Province, China, included 349 pregnant women in the second or third trimester; participants were recruited by convenience sampling and enrolled from October to December 2021. A general information questionnaire, the Interpersonal Reactivity Index (IRI), a purpose-designed empathy questionnaire and the Medical Outcomes Study 12-item Short-Form Health Survey (SF-12) were used to evaluate the pregnant women's general information, perceptions of empathy and HRQoL. Data were analysed using SPSS 22 at a threshold of P < 0.05. Descriptive analysis, Pearson correlation analysis, Student's t test, ANOVA, and multiple regression analysis were used for analysis. RESULTS The pregnant women's total empathy, physical component summary (PCS) and mental component summary (MCS) scores were 41.6 ± 9.0, 41.6 ± 7.6, and 47.7 ± 9.1, respectively. Correlation analysis revealed that the purpose-designed empathy questionnaire items were significantly positively correlated with perspective taking and empathic concern but were not correlated with the personal distress dimension and were only partially correlated with the fantasy dimension. Maternal physical condition during pregnancy, planned pregnancy, and occupational stress were predictors of the PCS score (β = 0.281, P < 0.01; β = 0.132, P = 0.02; β = -0.128, P = 0.02). The behavioural empathy item of our purpose-designed empathy questionnaire and empathic concern were important predictors of the MCS score (β = 0.127, P = 0.02; β = 0.158, P < 0.01), as well as other demographic and obstetric information, explaining 22.0% of the variance in MCS scores totally (F = 12.228, P < 0.01). CONCLUSIONS Pregnant women perceived lower empathy from their spouses and reported lower HRQoL. Perceived empathy, particularly behavioural empathy, may significantly impact pregnant women's MCS scores but has no effect on their PCS scores. Strategies that foster perceived empathy from spouses among pregnant women are essential for facilitating healthy pregnancies and potentially improving maternal and child health.

Abstract
BACKGROUND Aberrant iron metabolism is commonly observed in multiple tumor types, including hepatocellular carcinoma (HCC). However, as the key regulator of iron metabolism involved in iron absorption, the role of transferrin receptor (TFRC) in HCC remains elusive. METHODS The mRNA and protein expression of TFRC were evaluated in paired HCC and adjacent non-tumor specimens. The correlation between TFRC level and clinicopathological features or prognostic significance was also analyzed. The role of TFRC on biological functions was finally studied in vitro and in vivo. RESULTS The TFRC level was remarkably upregulated in HCC tissues compared to paired peritumor tissues. Overexpressed TFRC positively correlated with serum alpha-fetoprotein, carcinoembryonic antigen, and poor tumor differentiation. Multivariate analysis demonstrated that upregulated TFRC was an independent predictive marker for poorer overall survival and disease-free survival in HCC patients. Loss of TFRC markedly impaired cell proliferation and migration in vitro and notably suppressed HCC growth and metastasis in vivo, while overexpression of TFRC performed an opposite effect. Mechanistically, the mTOR signaling pathway was downregulated with TFRC knockdown, and the mTOR agonist MHY1485 completely reversed the biological inhibition in HCC cells caused by TFRC knockdown. Furthermore, exogenous ferric citrate (FAC) or iron chelator reversed the changed biological functions and signaling pathway expression of HCC cells caused by TFRC knockdown or overexpression, respectively. CONCLUSIONS Our study indicates that TFRC exerts an oncogenic role in HCC and may become a promising therapeutic target to restrain HCC progression.

Abstract
Objective: To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications. Methods: This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression. Results: The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion: Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Abstract
Gastric cancer remains a leading cause of cancer-related death worldwide, largely due to inadequate screening methods, late diagnosis, and limited treatment options. Liquid biopsy has emerged as a promising non-invasive approach for cancer screening and prognosis by detecting circulating tumor components like circulating tumor DNA (ctDNA) in the blood. Numerous gastric cancer-specific ctDNA biomarkers have now been identified. CtDNA analysis provides insight into genetic and epigenetic alterations in tumors, holding promise for predicting treatment response and prognosis in gastric cancer patients. This review summarizes current research on ctDNA biology and detection technologies, while highlighting clinical applications of ctDNA for gastric cancer diagnosis, prognosis, and guiding treatment decisions. Current challenges and future perspectives for ctDNA analysis are also discussed.

Abstract
Ferroptosis is identified as a novel type of cell death with distinct properties involved in physical conditions and various diseases, including cancers. It is considered that ferroptosis provides a promising therapeutic strategy for optimizing oncotherapy. Although erastin is an effective ferroptosis trigger, the potential of its clinical application is largely restricted by its poor water solubility and concomitant limitations. To address this issue, an innovative nanoplatform (PE@PTGA) that integrated protoporphyrin IX (PpIX) and erastin coated with amphiphilic polymers (PTGA) to evoke ferroptosis and apoptosis is constructed and exemplified using an orthotopic hepatocellular carcinoma (HCC) xenograft mouse model as a paradigm. The self-assembled nanoparticles can enter HCC cells and release PpIX and erastin. With light stimulation, PpIX exerts hyperthermia and reactive oxygen species to inhibit the proliferation of HCC cells. Besides, the accumulated reactive oxygen species (ROS) can further promote erastin-induced ferroptosis in HCC cells. In vitro and in vivo studies reveal that PE@PTGA synergistically inhibits tumor development by stimulating both ferroptosis- and apoptosis-related pathways. Moreover, PE@PTGA has low toxicity and satisfactory biocompatibility, suggesting its promising clinical benefit in cancer treatments.

Abstract
A crucial lesson gained through the pandemic preparedness and response to COVID-19 is that all measures for epidemic control must be law-based. The legal system is related not only to public health emergency management per se but also to all aspects of the institutional supporting system throughout the lifecycle. Based on the lifecycle emergency management model, this article analyses the problems of the current legal system and the potential solutions. It is suggested that the lifecycle emergency management model shall be followed to establish a more comprehensive public health legal system and to gather the intelligence and consensus of experts with different expertise, including epidemiologists, sociologists, economists, jurist and others, which will collaboratively promote the science-based legislation in the field of epidemic preparedness and response for the establishment of a comprehensive legal system for public health emergency management and with Chinese characteristics.

Abstract
Lipid metabolism reprogramming is a recognized hallmark of cancer cells. Identification of the underlying regulators of metabolic reprogramming in esophageal squamous cell carcinoma (ESCC) could uncover potential therapeutic targets to improve treatment. Here, we demonstrated that pre-mRNA processing factor 19 (PRP19) mediates reprogramming of lipid metabolism in ESCC. Expression of PRP19 was significantly upregulated in multiple ESCC cohorts and was correlated with poor clinical prognosis. PRP19 promoted ESCC proliferation in vitro and in vivo. Upregulation of PRP19 enhanced fatty acid synthesis through sterol regulatory element-binding protein 1 (SREBF1), a major transcription factor of lipid synthase. Moreover, PRP19 enhanced the stability of SREBF1 mRNA in an N6-methyladenosine-dependent manner. Overall, this study shows that PRP19-mediated fatty acid metabolism is crucial for ESCC progression. Targeting PRP19 is a potential therapeutic approach to reverse metabolic reprogramming in patients with ESCC. SIGNIFICANCE Upregulation of pre-mRNA processing factor 19 (PRP19) contributes to esophageal squamous cell carcinoma progression by reprogramming SREBF1-dependent fatty acid metabolism, identifying PRP19 as a potential prognostic biomarker and therapeutic target.

Abstract
Primary liver cancer (PLC) is a common gastrointestinal malignancy worldwide. While hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) are two major pathologic types of PLC, combined HCC and ICC (cHCC-ICC) is a relatively rare subtype that shares both hepatocyte and cholangiocyte differentiation. However, the molecular feature of this unique tumor remains elusive because of its low incidence and lack of a suitable animal model. Herein, we generated a novel spontaneous cHCC-ICC model using a Sleeping Beauty-dependent transposon plasmid co-expressing oncogenic Myc and AKT1 and a CRISPR-Cas9 plasmid expressing single-guide RNA targeting p53 into mouse hepatocytes via in situ electroporation. The histological and transcriptional analysis confirmed that this model exhibits cHCC-ICC features and activates pathways committing cHCC-ICC formation, such as TGF-β, WNT, and NF-κB. Using this model, we further screened and identified LAMB1, a protein involved in cell adhesion and migration, as a potential therapeutic target for cHCC-ICC. In conclusion, our work presents a novel genetic cHCC-ICC model and provides new insights into cHCC-ICC.

Abstract
GPM6A is a glycoprotein in endothelial cells, and its biological function in the development of hepatocellular carcinoma (HCC) is unknown. Through Affymetrix gene expression microarray and bioinformatic analysis, very low GPM6A expression was found in HCC tissue. The present study aims to explore the function and regulatory mechanism of GPM6A in HCC development and progression. Levels of GPM6A expression in HCC specimens from different disorders and various hepatoma cell lines were determined, and its role on cell proliferation was evaluated in hepatoma cells stably overexpressing GPM6A. Modulation of a specific microRNA (miRNA) on its expression and function was evaluated with miRNA mimetic transfection. Herein, it is reported that much lower GPM6A levels were found in HCC tissues than pericancerous liver tissues and correlated to a poor prognosis. GPM6A overexpression inhibited cell proliferation, suppressed colony formation, migration and invasion in two hepatoma cell types. Available evidence does not support that genetic and epigenetic dysregulation contributes significantly to GPM6A inactivation in HCC. Additional findings demonstrated that miR-96-5p acted directly on the 3'-UTR of the GPM6A gene and significantly decreased its mRNA and protein levels. MiR-96-5p transfection promoted proliferation, migration and invasion of SMMC-7721 and MHCC-97H hepatoma cells; whereas the function of oncogenic microRNA-96 was significantly inhibited in GPM6A-overexpressed hepatoma cells. In conclusion, GPM6A expression in HCC is commonly suppressed regardless its base disease types, and its low expression in HCC tissues is most likely attributed to upregulated miR-96-5p. GPM6A may function as a valuable biomarker for HCC progression and prognosis.

Abstract
Hepatocellular carcinoma (HCC) accounts for the predominant form of liver malignancy and presents a leading cause of cancer-related death globally. Sorafenib (SOR), a first-line targeted drug for advanced HCC treatment, has a battery of untoward side effects. Photothermal therapy (PTT) has been utilized as an effective adjuvant in synergy with other approaches. However, little is known about the tumoricidal efficacy of combining SOR with PTT for HCC. Herein, a novel versatile nanoparticle, Cu2-xSe@SOR@PEG (CSP), that is based on a photothermal Cu2-xSe core and SOR for simultaneously reinforcing PTT and reducing the adverse effects of SOR was constructed. The synthesized CSP exhibited a remarkably enhanced therapeutic effect upon 808 nm laser irradiation via dampening HCC cell propagation and metastasis and propelling cell apoptosis. The intravenous administration of CSP substantially suppressed tumor growth in a xenograft tumor mouse model. It was noted that the CSP manifested low toxicity and excellent biocompatibility. Together, this work indicates a promising and versatile tool that is based on synergistic PTT and molecular-targeted therapy for HCC management.

Abstract
Although sorafenib, a multi-kinase inhibitor, has provided noteworthy benefits in patients with hepatocellular carcinoma (HCC), the inevitable side effects, narrow therapeutic window, and low bioavailability seriously affect its clinical application. To be clinically distinctive, innovative drugs must meet the needs of reaching tumor tissues and cause limited side effects to normal organs and tissues. Recently, photodynamic therapy, utilizing a combination of a photosensitizer and light irradiation, was selectively accumulated at the tumor site and taken up effectively via inducing apoptosis or necrosis of cancer cells. In this study, a nano-chemo-phototherapy drug was fabricated to compose an iridium-based photosensitizer combined with sorafenib (IPS) via a self-assembly process. Compared to the free iridium photosensitizer or sorafenib, the IPS exhibited significantly improved therapeutic efficacy against tumor cells because of the increased cellular uptake and the subsequent simultaneous release of sorafenib and generation of reactive oxygen species production upon 532 nm laser irradiation. To evaluate the effect of synergistic treatment, cytotoxicity detection, live/dead staining, cell proliferative and apoptotic assay, and Western blot were performed. The IPS exhibited sufficient biocompatibility by hemolysis and serum biochemical tests. Also, the results suggested that IPS significantly inhibited HCC cell proliferation and promoted cell apoptosis. More importantly, marked anti-tumor growth effects via inhibiting cell proliferation and promoting tumor cell death were observed in an orthotopic xenograft HCC model. Therefore, our newly proposed nanotheranostic agent for combined chemotherapeutic and photodynamic therapy notably improves the therapeutic effect of sorafenib and has the potential to be a new alternative option for HCC treatment.

Abstract
Sorafenib resistance is often developed and impedes the benefits of clinical therapy in hepatocellular carcinoma (HCC) patients. However, the relationship between sorafenib resistance and tumor immune environment and adjuvant drugs for sorafenib-resistant HCC are not systemically identified. This study first analyzed the expression profiles of sorafenib-resistant HCC cells to explore immune cell infiltration levels and differentially expressed immune-related genes (DEIRGs). The prognostic value of DEIRGs was analyzed using Cox regression and Kaplan–Meier analysis based on The Cancer Genome Atlas. The primary immune cells infiltrated in sorafenib-resistant HCC mice were explored using flow cytometry (FCM). Finally, small-molecule drugs for sorafenib-resistant HCC treatment were screened and validated by experiments. The CIBERSORT algorithm and mice model showed that macrophages and neutrophils are highly infiltrated, while CD8+ T cells are downregulated in sorafenib-resistant HCC. Totally, 34 DEIRGs were obtained from sorafenib-resistant and control groups, which were highly enriched in immune-associated biological processes and pathways. NR6A1, CXCL5, C3, and TGFB1 were further identified as prognostic markers for HCC patients. Finally, nalidixic acid was identified as a promising antagonist for sorafenib-resistant HCC treatment. Collectively, our study reveals the tumor immune microenvironment changes and explores a promising adjuvant drug to overcome sorafenib resistance in HCC.

Abstract
The incidence of Siewert type II adenocarcinoma of the esophagogastric junction (AEG) is increasing year by year. Due to its special anatomical location and biological behavior, the treatment of AEG is still controversial in terms of lymph node dissection, the esophageal resection margin, range of gastrectomy, and the choice of reconstruction modality for postoperative gastrointestinal tract. The advent of the minimally invasive era has brought the treatment of Siewert type II AEG to a stage of gradual improvement and standardization. Experts of China are also actively exploring the value of minimally invasive surgery in the treatment of AEG through multicenter trials (CLASS-10, etc.). It is believed that based on the active development of many clinical studies, basic experimental studies and large prospective clinical studies, the strengthening of communication and cooperation among various disciplines and the innovative application of new technologies can bring greater survival benefits to patients.

Abstract
Urethral stricture is regarded as a common disease in urology whose treatment modalities usually include open surgery and endoluminal treatment. Endoluminal techniques have gradually become one of the essential treatments in urethral stricture due to easier operation, less trauma, faster recovery, higher safety and fewer complications. The popularity of plasma knife and laser, and the application of new urethral stents and grafts, make endoscopic surgery easier and less invasive. However, due to its anatomical particularity and diverse etiologies of urethral stricture, the endoluminal treatment is still not satisfactory and a considerable number of patients still experience poor long-term treatment effect. Non-operative managements, such as intracavitary brachytherapy, intracavitary injection of drugs or stem cells and new urinary catheters are also being explored in treating urethral stricture, which would improve the effect of endoscopic surgery. This review summarizes the clinical application and new progress of various kinds of endoluminal treatments and pharmacotherapy in urethral stricture at home and abroad. More prospective randomized controlled studies are needed to confirm its feasibility, effectiveness and optimal time of operation.

Abstract
Background Tumor-associated macrophages (TAM) are immunosuppressive cells that contribute to impaired anti-cancer immunity. Iron plays a critical role in regulating macrophage function. However, it is still elusive whether it can drive the functional polarization of macrophages in the context of cancer and how tumor cells affect the iron-handing properties of TAM. In this study, using hepatocellular carcinoma (HCC) as a study model, we aimed to explore the effect and mechanism of reduced ferrous iron in TAM. Methods TAM from HCC patients and mouse HCC tissues were collected to analyze the level of ferrous iron. Quantitative real-time PCR was used to assess M1 or M2 signature genes of macrophages treated with iron chelators. A co-culture system was established to explore the iron competition between macrophages and HCC cells. Flow cytometry analysis was performed to determine the holo-transferrin uptake of macrophages. HCC samples from The Cancer Genome Atlas (TCGA) were enrolled to evaluate the prognostic value of transferrin receptor (TFRC) and its relevance to tumor-infiltrating M2 macrophages. Results We revealed that ferrous iron in M2-like TAM is lower than that in M1-like TAM. In vitro analysis showed that loss of iron-induced immunosuppressive M2 polarization of mouse macrophages. Further experiments showed that TFRC, the primary receptor for transferrin-mediated iron uptake, was overexpressed on HCC cells but not TAM. Mechanistically, HCC cells competed with macrophages for iron to upregulate the expression of M2-related genes via induction of HIF-1α, thus contributing to M2-like TAM polarization. We further clarified the oncogenic role of TFRC in HCC patients by TCGA. TFRC is significantly increased in varieties of malignancies, including HCC, and HCC patients with high TFRC levels have considerably shortened overall survival. Also, TFRC is shown to be positively related to tumor-infiltrating M2 macrophages. Conclusions Collectively, we identified iron starvation through TFRC-mediated iron competition drives functional immunosuppressive polarization of TAM, providing new insight into the interconnection between iron metabolism and tumor immunity.

Abstract
DNA self-assembled nanostructures have been considered as effective vehicles for biomolecule delivery because of their excellent biocompatibility, cellular permeability, noncytotoxicity, and small size. Here, we report an efficient antiviral strategy with self-assembled tetrahedral framework nucleic acids (tFNAs) delivering small interfering RNA (t-siRNA) to silence classical swine fever virus (CSFV) gene in porcine host cells. In this study, two previously reported siRNAs, C3 and C6, specifically targeting the CSFV genome were selected and modified on tFNAs, respectively, and termed t-C3 and t-C6. Results indicate that t-C3 and t-C6 can inhibit the viral proliferation of CSFV in kidney derived porcine cells, PK-15, effectively and that inhibition was markedly stronger than free siRNA-C3 or siRNA-C6 only. In addition, the DNA nanostructure also has high cargo-carrying capacity, allowing to deliver multiple functional groups. To improve the antiviral ability of tFNAs, a dual-targeting DNA nanostructure t-C3-C6 was constructed and used to silence the CSFV gene in porcine host cells. This study found that t-C3-C6 can inhibit the viral release and replication, exhibiting outstanding anti-CSFV capabilities. Therefore, these dual-targeting tFNAs have great potential in virus therapy. This strategy not only provides a novel method to inhibit CSFV replication in porcine cells but also verifies that tFNAs are effective tools for delivery of antiviral elements, which have great application potential.

Abstract
The detection rate of submucosal tumors in the gastric cardia increases year by year. Most of these tumors are benign or borderline tumors, among which leiomyoma and gastrointestinal stromal tumor are more common. The functional preservation of the gastric cardiac region is closely related to the anatomical structure of the esophagogastric junction. The esophageal reflux is mainly evaluated directly or indirectly by upper gastrointestinal radiography, gastroscopy, CT examination and manometric measurements of the lower esophagus. For tumors at this specific region, the risk of lymph node metastasis is very low, and according to the tumor free principle, usually only complete removal of the tumor is required. We aim to introduce the minimally invasive and function preserving procedures, including endoscopic therapy alone, laparoscopic and endoscopic cooperative surgery, and totally laparoscopic surgery. The selection of this tailored treatment should be based on the tumor location, size, shape and growth pattern (intraluminal or extraluminal), and the experience of the surgical team, so as to improve postoperative quality of life of the patients.

Abstract
Sorafenib, a multitargeted kinase inhibitor, has been reported to elicit a limited therapeutic effect in hepatocellular carcinoma (HCC). Currently, phototherapy, including photodynamic therapy (PDT) and photothermal therapy (PTT), is emerging as a powerful modality for cancer therapy. However, few studies have been reported the effectiveness of the combination of sorafenib with PDT and PTT in HCC. Herein, we designed and synthesized bovine serum albumin (BSA)-coated zinc phthalocyanine (ZnPc) and sorafenib (SFB) nanoparticle (ZnPc/SFB@BSA). The obtained ZnPc/SFB@BSA was able to trigger PDT, PTT, and chemotherapy. After irradiation by a 730 nm light, ZnPc/SFB@BSA significantly suppressed HCC cell proliferation and metastasis while promoted cell apoptosis in vitro. Furthermore, intravenous injection of ZnPc/SFB@BSA led to dramatically reduced tumor growth in an orthotopic xenograft HCC model. More importantly, ZnPc/SFB@BSA presented low toxicity and adequate blood compatibility. Therefore, a combination of ZnPc with sorafenib via BSA-assembled nanoparticle can markedly suppress HCC growth, representing a promising strategy for HCC patients.

Abstract
BACKGROUND The mechanistic target of rapamycin (mTOR) pathway, containing mTOR complex 1 (mTORC1) and mTORC2, is dysregulated in multiple cancers, including hepatocellular carcinoma (HCC). Mammalian lethal with sec-13 protein 8 (mLST8) is a shared constituent of both mTORC1 and mTORC2, yet little is known regarding its role in HCC development. METHODS mLST8 expression was detected in a total of 186 pairs of HCC and adjacent non-tumor specimens. The correlation between mLST8 level and clinicopathological features or prognostic significance were analyzed. The role of mLST8 on biological functions was also preliminarily studied. RESULTS The study revealed that the mLST8 level was dramatically higher in HCC specimens than in adjacent non-tumor specimens. mLST8 overexpression positively correlated with tumor size, differentiation, and vessel invasion. Cases with elevated mLST8 level had more unfavorable overall survival (OS) and disease-free survival (DFS) than those with downregulated mLST8 level. Multivariate analysis demonstrated that mLST8 upregulation was an independent predictive marker for OS and DFS. Calibration curves from nomogram models indicated an excellent coherence between nomogram prediction and actual situation. Decision curve analysis proved that mLST8-based nomograms presented much higher predictive accuracy when compared with conventional clinical staging systems. Mechanistically, mLST8 enhanced cell proliferation and invasion through the AKT (protein kinase B) pathway. CONCLUSIONS Our study demonstrates that mLST8 exerts an oncogenic role in HCC and may become a promising prognostic biomarker and therapeutic target for HCC patients.

Abstract
Upregulated ubiquitin-conjugating enzyme E2M (UBE2M) is associated with poor prognosis in malignancies; However, the phenotype and mechanism of action of UBE2M in hepatocellular carcinoma (HCC) remain elusive. Here, we report that UBE2M is overexpressed and correlated with poor prognosis in HCC patients. The UBE2M level is an independent prognostic factor for HCC patients. UBE2M knockdown inhibits HCC cell proliferation, migration, and invasion, whereas its overexpression has an opposite effect. Mechanistically, upregulated UBE2M exerts oncogenic effects by translocation of accumulated β-catenin from the cytoplasm to the nucleus, thus activating downstream β-catenin/cyclin D1 signaling. In summary, our study demonstrates a notable role of UBE2M in promoting the growth of HCC, providing a novel strategy for HCC prevention and treatment.

A total of 405 healthy hens (HY-Line White, 50-week-old) were randomly divided into 3 treatments, with 9 replications per treatment and 15 birds per replication. The dietary treatments included a basal diet supplemented with inorganic trace minerals at commercial levels (CON), a basal diet supplemented with inorganic trace minerals at 1/3 commercial levels (ITM), and a basal diet supplemented with proteinated trace minerals at 1/3 commercial levels (TRT). The trial lasted 56 D (8 wk). Compared with the CON group, the ITM group showed decrease in (P < 0.05) egg production, eggshell strength, eggshell palisade layer, palisade layer ratio, serum estrogen, luteinizing hormone, glycosaminoglycan concentration, and carbonic anhydrase activity and increase in (P < 0.05) egg loss and mammillary layer ratio. However, the TRT group almost kept all the indices close to the CON group (P > 0.05). Furthermore, hens fed with low inclusion levels of organic trace minerals had smaller mammillary knobs (P < 0.05) than those in the CON and ITM groups. In conclusion, hens fed with low inclusion levels of proteinated trace minerals had better performance and eggshell strength than those fed with identical levels of inorganic compounds; organic trace minerals improved eggshell quality by improving the eggshell ultrastructure of laying hens during the late laying period.

Abstract
Background Growing evidence suggests that the ubiquitin-proteasome system is involved in the pathogenesis and recurrence of hepatocellular carcinoma (HCC); yet, little is known about the role of ubiquitin-conjugating enzyme E2T (UBE2T) in HCC. Materials and methods UBE2T levels were detected in HCC tissues and hepatoma cell lines using quantitative reserve transcriptase-polymerase chain reaction and Western blot analysis. Next, the changes of phenotypes after UBE2T knockdown or overexpression were evaluated using in vitro methods. Finally, the mechanism of UBE2T in HCC was tested using ex vivo and in vivo methods. Results In the present study, we reported that UBE2T mRNA and protein levels were significantly upregulated in HCC tissues compared to adjacent non-tumor tissues. Additionally, suppression of UBE2T expression inhibited proliferation, colony formation, tumorigenesis, migration, and invasion of hepatoma cells, whereas UBE2T overexpression led to the opposite outcomes. Moreover, suppression of UBE2T expression resulted in an increase in G2/M phase and a decrease in the percentage of cells in G1 phase, which indicated a cell cycle arrest at the G2/M phase. In contrast, the percentage of cells in G2/M phase decreased following UBE2T overexpression. Further study indicated that UBE2T regulated the G2/M transition by modulating cyclin B1 and cyclin-dependent kinase 1. Conclusion Taken together, the findings of the present study uncover biological functions of UBE2T in hepatoma cells, and delineate preliminary molecular mechanisms of UBE2T in modulating HCC development and progression.

Abstract
Long non-coding RNAs (lncRNAs) have been shown to contribute to progression and prognosis of hepatocellular carcinoma (HCC). However, expression profiling and interaction of lncRNAs with messenger RNAs (mRNAs) and microRNAs (miRNAs) remain largely unknown in HCC. The expression profiling of lncRNAs, mRNA and miRNAs was obtained using microarray. The Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analysis were used to characterize potential functions of differentially expressed mRNAs. Cytoscape was applied to construct an lncRNA-miRNA-mRNA co-expression network and candidate lncRNAs were validated via quantitative PCR in 30 pairs of HCC and adjacent tumor-free tissues. In this study, 1,056 upregulated and 1,288 downregulated lncRNAs were identified, while 2,687 mRNAs and 6 miRNAs were aberrantly expressed in HCC compared with adjacent tumor-free tissues. Potential functions of differentially expressed mRNAs were demonstrated to significantly participate in modulating critical genes in the cell cycle, such as cyclin E1 and cyclin B2. After screening, 95 lncRNAs, 5 miRNAs and 36 mRNAs were recruited for construction of lncRNA-mRNA-miRNA co-expression network in the cell cycle pathway. Subsequently, the top 5 lncRNAs that potentially modulate critical genes in the cell cycle were selected as the candidates for further verification. Kaplan-Meier curves using the Cancer Genome Atlas database showed that 13 targeted mRNAs were associated with overall survival of HCC patients. Finally, three lncRNAs, including ENST00000522221, lnc-HACE1-6:1 and lnc-ICOSLG-11:1, are significantly upregulated in HCC tissues compared with adjacent tumor-free tissues. These findings suggest that lncRNAs play essential roles in the pathogenesis of HCC via regulating coding genes and miRNAs, and may be important targets for diagnosis and treatment of this disease.

Abstract
Background: Aberrant expression of pepsinogen C (PGC) has been observed in human cancers. However, its role in hepatocellular carcinoma (HCC) remains to be established. The goal of this study is to illustrate PGC expression and to evaluate its clinical relevance in HCC. Materials and methods: PGC expression was examined in 75 pairs of HCC and adjacent non-tumor tissues using tissue microarray. The correlations between its expression and clinical parameters were also analyzed. Results: PGC overexpression was significantly associated with larger tumor size (≥5 cm; P=0.017) and incomplete encapsulation (P<0.0001). Cox regression model demonstrated that PGC expression and tumor size were independent prognostic factors for overall survival (OS) and disease-free survival (DFS) in HCC. The subgroup analysis by Kaplan–Meier uncovered that OS and DFS were much worse in high PGC level group than in low PGC level group with large tumor size subgroup, while no difference of OS was noted between the two groups with low tumor size subgroup. Conclusion: PGC plays a tumorigenesis role in HCC progression, which may lead to a novel insight to the potential biomarker and novel therapeutic strategies for HCC patients.

Abstract
The mechanistic target of rapamycin (mTOR) pathway coordinates organismal growth and homeostasis in response to growth factors, nutrients, and cellular energy stage. The pathway regulates several major cellular processes and is implicated in various pathological conditions, including hepatocellular carcinoma (HCC). This review summarizes recent advances of the mTOR pathway, highlights the potential of the mTOR pathway as a therapeutic target, and explores clinical trials targeting the mTOR pathway in HCC. Although the review focuses on the mTOR pathway involved in HCC, more comprehensive discussions (eg, developing a rational design for future trials targeting the mTOR pathway) are also applicable to other tumors.

Abstract
AIMS AND OBJECTIVES To develop and validate an instrument to measure nurses' empathy motivation in China (See Supporting Information Appendix S1). BACKGROUND Nurses are increasingly expected to empathise with patients in clinical settings. However, research investigating nurses' empathy motivation in China is lacking, and no specific instrument exists worldwide. DESIGN Two-stage cross-sectional study, which follows the STROBE guidelines. Instrument development and psychometric evaluation were used (See Supporting Information Appendix S1). METHODS A literature review and qualitative interviews with nurses were conducted to generate the initial items. Convenience samples of 340 (for item analysis) and 640 (for psychometric evaluation) clinical nurses working at four tertiary hospitals in Anhui Province were recruited. The scale was validated by content validity, surface validity and item analysis. A total of 640 participants were randomly divided into two equal groups. Exploratory factor analysis (EFA) was used with varimax rotation, confirmatory factor analysis (CFA) and internal consistency reliability to analyse the psychometric properties of the scale (See Supporting Information Appendix S1). RESULTS From the initial 90-item pool, 27 items were retained by the item analysis. The EFA (N = 290) showed the following six factors on the scale explained 71.266% of the overall variance: amotivation, external regulation, introjected regulation, identified regulation, integrative regulation and intrinsic motivation. Furthermore, when limited to three factors, that is autonomy motivation, controlled motivation and amotivation, 56.578% of the variance was explained. The findings showed high internal consistency. The six-factor solution and three-factor solution of the scale, including 27 items, were both confirmed by the CFA, for example χ2 /df = 1.744, 2.261; RMSEA = 0.051, 0.066; GFI = 0.882, 0.847; TLI = 0.942, 0.902; and RMR = 0.039, 0.049, respectively. CONCLUSIONS The nurses' empathy motivation scale presents good psychometric properties and can be used to explore nurses' empathy motivation in China (See Supporting Information Appendix S1). RELEVANCE TO CLINICAL PRACTICE This study offers insight into nurses' complicated reasons for exhibiting empathy.

Abstract
Nitrite detection plays a very important role in environmental monitoring and for industrial purposes. The commonly used colorimetric analysis requires the measurement of a system's calibration curve by asynchronously preparing and detecting a dozen standard samples, leading to time-consuming, slow and cumbersome procedures. Here, we present a differential colorimetry method that determines the nitrite level based on the paired chromaticity gradient, formed by coupling the colour reaction into the microfluidic network. The two gradients reshape each other and contain enough information for the quantitative analysis of the sample being tested, without the need for a calibration curve. The independence of the two gradients of the absorbance change caused by the detecting system and water quality results in a high stability and anti-interference performance, with the assistance of its self-correcting ability. This differential colorimetry method requires little time and energy consumption as only one sample is needed. Standard nitrite solutions of 0.50 mM and 0.33 mM have been determined with an error of 1.16% and 0.50%, respectively. These measurements are advantageous in terms of greater stability by up to 10 times and accuracy by 6 times, compared with the calibration curve approaches. It is foreseeable that this differential colorimetry method will find a wide range of applications in the field of chemical detection.

Abstract
Objective: To analyze the clinical characteristics and prognosis of anorectal malformations (ARMs) and explore the influencing factors of postoperative anal function in Anhui Province of China.Methods: We performed a retrospective study of ARM patients diagnosed from 2013 to 2016 at Anhui Provincial Children's Hospital. A total of 332 infants with ARM were enrolled in the survey. Demographic characteristic and clinical data were collected. Follow-up study was required to evaluate anal function after the operation and Logistic regression analysis was used for analyzing the influencing factors of prognosis.Results: A total of 253 males and 79 females were studied, with a ratio of 3.2:1. Abdominal distention was the most common presenting symptom, followed by vomiting. Of the cases, 53.0% (176/332) combined with other congenital malformations. The incidence of other malformations in intermediate and high ARM group was significantly higher than that in the low ARM group. Of the cases, 280 underwent anoplasty. 188, 73, 19 cases were treated with one-stage perineal anoplasty, posterior sagittal anorectoplasty, laparoscopically assisted anorectal pull-through, respectively. The result of follow-up study showed that the excellent and good rate of postoperative anal function was up to 83.3%. Type of ARM, combined with other malformations and the times of anoplasty were related to the anal function postoperatively.Conclusions: ARM occurs mainly in male infants. The incidence of associated abnormalities in ARM patients was high. Intermediate- and high-type, combined with other malformations and more times of anoplasty increased the risk of anal dysfunction postoperatively. Multicenter, prospective randomized-controlled studies were needed to clarify the curative effect of different surgical approaches.

Abstract
microRNA-19a-3p (miR-19a-3p) has been reported to regulate cell proliferation in hepatocellular carcinoma (HCC), but its role in HCC metastasis remains unknown. In this study, miR-19a-3p was noted to be upregulated in HCC specimens and cell lines. Aberrant expression of miR-19a-3p stimulated HCC cell metastasis, and phosphatase and tensin homolog (PTEN) was shown to be a direct target of miR-19a-3p. miR-19a-3p-mediated HCC metastasis was reversed by restoration of PTEN or could be imitated by silencing of PTEN. Modulation of miR-19a-3p also altered expression of phosphorylated Akt, a downstream mediator of PTEN. Moreover, aberrant expression of miR-19a-3p induced sorafenib resistance by regulating the PTEN/Akt pathway. In conclusion, ectopic expression of miR-19a-3p contributes to HCC metastasis and chemoresistance by modulating PTEN expression and the PTEN-dependent pathways.

Abstract
Pre-mRNA processing factor 19 (Prp19) is involved in many cellular events including pre-mRNA processing and DNA damage response. However, the pathological role of Prp19 in hepatocellular carcinoma (HCC) is still elusive. Here, we reported that Prp19 was increased in most HCC tissues and HCC cell lines, and its overexpression in HCC tissues was positively correlated with vascular invasion, tumor capsule breakthrough and poor prognosis. Prp19 potentiated migratory and invasive abilities of HCC cells in vitro and in vivo. Furthermore Prp19 facilitated Twist1-induced epithelial-mesenchymal transition. Mechanistic insights revealed that Prp19 directly binded with TGF-β-activated kinase1 (TAK1) and promoted the activation of p38 mitogen-activated protein kinase (MAPK), preventing Twist1 from degradation. Finally Prp19/p38 MAPK/Twist1 axis was attested in nude mice xenografts and HCC patient specimens. This work implies that the gain of Prp19 is a critical event during the progression of HCC, making it a promising target for malignancies with aberrant Prp19 expression.

Abstract
Real-time detection of phosphate has significant meaning in marine environmental monitoring and forecasting the occurrence of harmful algal blooms. Conventional monitoring instruments are dependent on artificial sampling and laboratory analysis. They have various shortcomings for real-time applications because of the large equipment size and high production cost, with low target selectivity and the requirement of time-consuming procedures to obtain the detection results. We propose an optofluidic miniaturized analysis chip combined with micro-resonators to achieve real-time phosphate detection. The quantitative water-soluble components are controlled by the flow rate of the phosphate solution, chromogenic agent A (ascorbic acid solution) and chromogenic agent B (12% ammonium molybdate solution, 80% concentrated sulfuric acid and 8% antimony potassium tartrate solution with a volume ratio of 80 : 18 : 2). Subsequently, an on-chip Fabry-Pérot microcavity is formed with a pair of aligned coated fiber facets. With the help of optical feedback, the absorption of phosphate can be enhanced, which can avoid the disadvantages of the macroscale absorption cells in traditional instruments. It can also overcome the difficulties of traditional instruments in terms of size, parallel processing of numerous samples and real-time monitoring, etc. The absorption cell length is shortened to 300 μm with a detection limit of 0.1 μmol L-1. The time required for detection is shortened from 20 min to 6 seconds. Predictably, microsensors based on optofluidic technology will have potential in the field of marine environmental monitoring.

Abstract
OBJECTIVE To analyze the clinical and epidemiological features of patients with infantile hypertrophic pyloric stenosis (IHPS) so as to provide scientific evidence for diagnosis and prevention of IHPS. METHODS We performed a retrospective study of infants with IHPS diagnosed from 2012 to 2015 at Anhui Provincial Children's Hospital. Demographic characteristics and clinical data were collected. RESULTS Three hundred four patients (264 males and 40 females) were studied, of which 94.7% were full term and 75.7% were bottle fed or mixed fed; 16.8% of the patients had other congenital malformations in combination with IHPS. The proportion of IHPS cases with hyponatremia, hypokalemia, and hypochloremia was 18.4%, 12.5%, and 53.9%. A negative correlation was found between duration of disease and serum electrolytes. The mean pyloric muscle thickness, pyloric length, and diameter were 4.8 ± 0.7 mm, 19.4 ± 2.5 mm, and 13.3 ± 1.8 mm, respectively. There were significant differences in muscle thickness, pyloric length, and diameter between short (≤14 d) and long (>14 d) durations of disease. All patients underwent pyloromyotomy, and postoperative recovery was good. CONCLUSIONS IHPS occurs mainly in male, full-term, bottle-fed or mixed-fed infants. Patients with long duration of disease were more likely to develop electrolyte disorder and thicker muscle layer. More attention should be paid to early discovery and diagnosis, which will help to improve the curative effect and prognosis of IHPS.

Abstract
Background The mechanism of Nova1’s role in hepatocellular carcinoma has not been delineated. Also its interaction with GABAA receptor γ2 in HCC is unveiled. This study is aimed to make it clear the distribution, prognostic value of GABAARγ2 in human hepatocellular carcinoma. And its role in HCC tumorigenesis under the regulation of its alternative splicing factor Nova1. Methods Immunohistochemistry staining was used to investigate the distribution and clinical significance of GABAARγ2 protein expression in hepatocellular carcinoma. In vivo tumorigenticity test was conducted in nude mice by regulation the expression of Nova1. Later, western blot and co-immunoprecipitation were carried out to verify the interaction between Nova1 and GABAARγ2 in HCC tissue. Results Immunohistochemical staining showed GABAARγ2 expression in HCC. Survival analysis showed intratumoral GABAARγ2 was an independent prognostic factor for overall survival (OS) and disease free survival (DFS). Up-regulation of Nova1 expression promotes subcutaneous HCC growth in nude mice and western blot showed the ectopic expression of Nova-1 restro-regulates the expression of GABAARγ2 and GABA. Protein level interaction of GABAARγ2 and Nova-1 was evidenced by co-immunoprecipitation. Conclusions Nova1 interacts with GABAARγ2 not only in CNS but also in HCC. Nova1’s potential mechanism as an oncogene may due to its interaction with GABAA Rγ2. A better understanding of the mechanism of Nova1 for HCC progression provides a novel target for an optimal immunotherapy against this fatal malignancy.

Abstract
Objective: To investigate the expression of endothelial protein C receptor(EPCR)and its roles in plasma and placenta of patients with early onset severe preeclampsia. Methods: Sixty cases of severe preeclampsia women who delivered in Xuzhou Maternity and Child Health Care Hospital from March 2014 to February 2016, were recruited, which included 30 cases with early onset severe preeclampsia(early onset group, gestational week <34 weeks)and 30 patients with late onset severe preeclampsia(late onset group, gestational week ≥34 weeks). Thirty cases of healthy late pregnant women at the same period(gestational week ≥34 weeks)were selected as control group. Immunohistochemistry SP method was applied to detect the expression of in EPCR placenta. Reverse transcription(RT)- PCR was used to detect the expression of EPCR mRNA in placenta. ELISA method was used to detect the levels of soluble EPCR(sEPCR)level in plasma of the pregnant women of the three groups. Results: The expression of EPCR in placenta mainly distributed in the membrane and cytoplasm of placental syncytiotrophoblasts and vascular endothelial cells, a few in the cell nucleus. The expression of EPCR in early onset group(57%, 17/30)was significantly lower than that in late onset group(93%, 28/30; χ2=25.165, P=0.001). The expression of EPCR in late onset group had no significant difference from that in control group(97%, 29/30; χ2=0.540, P= 0.910). The expression of EPCR mRNA in placenta of early onset group(0.40±0.07)was significantly lower than that in late onset group(0.91±0.06; t=-30.044, P=0.001), while there was no statistical difference of the expression of EPCR mRNA between the late onset group and the control group(0.92±0.07; t=-0.631, P=0.538). Plasma sEPCR level in early onset group, late onset group and control group were(231 ± 11),(124±6)and(121±4)μg/L respectively, which is higher in early onset group than that in late onset group(t=48.080, P=0.001). There was no statistical difference of plasma sEPCR level between the late onset group and the control group(t=2.534, P=0.100). Conclusions: The pathogenesis of early onset and late onset severe preeclampsia may be different. Decreased expression of EPCR in placenta may be associated with the pathogenesis of early onset severe preeclampsia.

Abstract
OBJECTIVE To investigate some important issues for diagnosis and treatment of idiopathic normal-pressure hydrocephalus (iNPH), such as standardized pre-operative assessment, initial pressure value of diverter pump, and pressure regulation during follow-up. METHODS Twenty six iNPH patients (21 males) who treated in Department of Neurosurgery of 2nd Affiliated Hospital of Zhejiang University School of Medicine from 2011 to 2015 were analyzed retrospectively. The average age was 60.5 year. The analysis focused on the treatment process of iNPH, initial pressure value of diverter pump, choice of diverter pump, and pressure regulation during follow-up. RESULTS As a result, 24 cases (92.3%) had a good prognosis based on their imaging and clinical manifestations. Based on the literature and their clinical experiences, this department established a diagnosis and treatment procedure of iNPH and a pressure regulation procedure for the follow-up of iNPH. Moreover, it is proposed that choosing an anti-gravity diverter pump and making an initial pressure value 20 mmH2O less than pre-surgical cerebrospinal pressure may be beneficial for the prognosis. CONCLUSION This standardized diagnosis and treatment procedure for iNPH is practical and effective.

Abstract
OBJECTIVE To evaluate the application value of evoked potentials (EP) monitoring in patients undergoing aorta-iliac bypass for total thoracoabdominal aorta aneurysm repair (tTAAAR). METHODS A prospective study, with a total of 31 patients undergoing tTAAAR and intraoperative EP monitoring from June 2014 to April 2015 was carried out. The results of intraoperative evoked potentials, clinical outcomes and follow-up data of patients were collected for further evaluation. RESULTS The EP wave disappeared [motor evoked potentials for (55.6±18.1) min, somatosensory evoked potentials for (50.3±18.7) min] after proximal descending aorta being clamped, and gradually recovered after the segment arteries of spine cord were reconstructed. The EP wave was restored to normal level at the end of operation in all the cases. The somatosensory evoked potentials remained unchanged in 2 cases (false negative). One case died after operation. No spinal cord injury occurred. The median follow-up after operation was 10 months (5-14 months). There was no delayed neurological deficit. CONCLUSION EP provided an on-line monitoring of the condition of spinal cord function, which become an intraoperative protocol to avoid the irreversible injury of spinal cord.

Abstract
BACKGROUND AND AIM MicroRNA-18a (miR-18a) has been reported to be upregulated in gastric cancer (GC) tissues compared with normal gastric tissues. However, little is known about its prognostic value and biological roles. METHODS In this study, miR-18a expression in gastric adenocarcinoma (GAC) tissues and adjacent non-tumor tissues was validated by in situ hybridization, and the predictive values of miR-18a were explored. The biological roles of miR-18a and the underlying signal pathway were investigated in GC cell lines. RESULTS Overexpressed intra-tumoral miR-18a was associated with poor survival rate and was an independent prognostic factor for overall survival rate (P < 0.001) in GC patients. Forced expression of miR-18a remarkably enhanced cell proliferation, migration, and invasion in GC cells, while inhibition of miR-18a caused the opposite effects. Further study showed that miR-18a suppressed the expression of interferon regulatory factor 2 (IRF2) by directly binding to its 3'-untranslated region. Moreover, miR-18a expression levels are inversely correlated with IRF2 in human GC tissues. Western blot showed that forced expression of miR-18a could not only downregulate the expression of IRF2, but also inhibit the expression of P53, suggesting that IRF2 might play as a tumor suppressor by regulating P53 signaling in GC. CONCLUSION miR-18a modulated P53 expression by directly targeting IRF2 and had a high predictive value for prognosis of GAC patients. These results may lead to identification of therapeutic candidates of GC.

Abstract
As cholangiographic features of IgG4-related sclerosing cholangitis (IgG4-SC) resemble those of cholangiocarcinoma, it is highly confusing between the 2 conditions on the basis of cholangiographic findings. This study presents a case of extensive metastatic cholangiocarcinoma with IgG4-SC misdiagnosed as isolated IgG4-SC, and reviews recent studies of the 2 diseases.A 56-year-old man with no family history of malignant tumors or liver diseases presented with recurrent mild abdominal pain and distention for 3 months. Magnetic resonance cholangiopancreatography showed a 3.7 cm nodular lesion with unclear boundary in segment VI of the liver. Serum IgG4 and CA19-9 were slightly elevated. Histopathological examination was consistent with the consensus statement on the pathology of IgG4-SC. IgG4-SC was thus considered. Due to his mild symptoms, glucocorticoid was not given at first. However, 3 months after his first admission, he had more severe abdominal pain and further elevated serum CA19-9. Actually he was found suffering from extensive metastatic cholangiocarcinoma with IgG4-SC by exploratory laparotomy.The present case serves as a reminder that extensive metastatic cholangiocarcinoma with or without IgG4-SC may be misdiagnosed as an isolated IgG4-SC case if one relies solely on elevated serum and tissue IgG4 levels. We emphasize on the importance of repeated core needle biopsy or exploratory laparoscopy/laparotomy before immunosuppressive drugs are given, and on follow-up of imaging findings and serum CA19-9 once immunosuppressive therapy is started.

Abstract
The aim of the study was to investigate the influence of serum testosterone concentrations on bone mineral densities (BMDs) in healthy aged men in Shanghai area. Eighty-four participants, registered in the physical examination center of our hospital were included. Liquid chromatography tandem mass spectrometry (LC-MS/MS) was used to measure concentrations of total testosterone (TT) and free testosterone (FT) in serum. BMDs of the lumbar spine, femoral neck, the trochanter major, and Ward's triangle were determined with dual energy X-ray absorptiometry (DXA). The correlations of TT and FT with BMDs at the different skeleton sites were analyzed; stratified analyses by age were performed with 10-year range groups and the changing trends of TT and FT with increasing age were further investigated. In addition, we performed a stratified quartile TT and FT analysis of their correlations with BMDs of different bones in each group. The average age of the participants was 71.8 ± 9.6 years (50-90 years). In a stratified analysis by age, no significant TT changes with increasing age was found, but there was a significant decrease of FT in men older than 80 years (p<0.05). In a stratified FT quartile analysis, FT in the first quartile group correlated significantly with BMDs of the lumbar spine, femoral neck and Ward's triangle; however, there was only a significant correlation between FT and BMD of the femoral neck after adjustment for age and body mass index (BMI). FT blood serum concentrations decreased significantly in healthy men aged over 80 and positively correlated with BMDs of femoral necks.

Abstract
Published data on the association between interleukin (IL)-18 gene polymorphisms (-137 C/G, -607 A/C) and type 1 diabetes (T1D) risk are inconclusive. To obtain a more precise estimation of the association between the IL-18 gene polymorphisms and T1D, a meta-analysis was performed. A total of 11 studies including 5,945 cases and 6,404 controls were included in the analysis of the association between -137 C/G and T1D risk. No significant association between -137 C/G and T1D risk was observed in the total population [C vs. G: odds ratio (OR)=1.02, 95% confidence interval (CI)=0.87-1.20; CC + CG vs. GG: OR=1.05, 95% CI=0.87-1.25; CC vs. CG + GG: OR=0.96, 95% CI=0.68-1.36]. No significant association was identified in the stratified analysis for all the genetic models in the European population. Concerning -607 A/C, 10 studies involving 3,048 patients and 3,377 controls were included in this meta-analysis. When all the studies were pooled, the results showed no evidence for a significant association between IL-18 -607 A/C polymorphism and T1D risk (A vs. C: OR=0.93, 95% CI=0.81-1.06; AA + AC vs. CC: OR=0.99, 95% CI=0.89-1.10; AA vs. AC + CC: OR=0.81, 95% CI=0.60-1.09). In addition, similar results were obtained in the subgroup analysis based on ethnicity. In summary, the present meta-analysis suggests a lack of association between the two polymorphisms (-137 C/G, -607 A/C) in the IL-18 gene and T1D. Due to the limitation of the number of the studies, the conclusions drawn should be considered with caution. Larger scale primary studies are required to evaluate the association between IL-18 gene polymorphisms and T1D.

Abstract
Neuro-oncological ventral antigen 1 (Nova1) is a neuron-specific RNA-binding protein in human paraneoplastic opsoclonus-myoclonus ataxia accompanying with malignant tumors, but its role in hepatocellular carcinoma (HCC) remains elusive. In this study, we found that overexpressed intratumoral Nova1 was associated with poor survival rate and increased recurrence rate of HCC, especially early recurrence, and was an independent prognostic factor for overall survival rate and tumor recurrence. HCC cell lines over-expressing Nova1 exhibited greater potentials in cell proliferation, invasion and migration, while knockdown of Nova1 had the opposite effects. All these findings indicate that Nova1 may act as a prognostic marker for poor outcome and high recurrence in HCC.

Abstract
Nucleotide-binding oligomerization domain 2 (NOD2) is one of the most prominent member of the NOD-like receptors protein family that functions as intracellular pattern recognition receptors. Numerous studies have suggested the importance of NOD2 in defensing against microbial infections, regulation of the inflammatory process. It is shown that NOD2 contributes to the pathogenesis of various autoimmune and chronic inflammatory diseases, such as Crohn's disease, rheumatoid arthritis. The aim of this study is to summarize our current understandings of NOD2 function and the role of NOD2 in systemic lupus erythematosus (SLE). The following databases were searched: Pubmed, EMBASE and Web of Science for English-language sources, using the terms "lupus," "systemic lupus erythematosus," ''SLE," "immunity," "inflammatory" and "NOD2." Emerging data evidences that NOD2 has important biological effects in autoimmunity and inflammatory and might take part in the pathogenesis of SLE. Studies exploring the relationship between NOD2 and SLE are very limited. Whether NOD2 could be a potentially valuable therapeutic target for treatment for SLE, more understanding of the mechanism of NOD2 is needed in the future in SLE.

Abstract
Pre-mRNA processing factor 19 (Prp19) activates pre-mRNA spliceosome and also mediates DNA damage response. Prp19 overexpression in cells with functional p53 leads to decreased apoptosis and increases cell survival after DNA damage. Here we showed that in hepatocellular carcinoma (HCC) cells with inactive p53 or functional p53, Prp19 was down-regulated due to the impaired stability under chemotherapeutic drug treatment. Silencing Prp19 expression enhanced apoptosis of HCC cells with or without chemotherapeutic drug treatment. Furthermore high level of Prp19 may inhibit chemotherapeutic drugs induced apoptosis in hepatocellular carcinoma cells through modulating myeloid leukemia cell differentiation 1 expression. These results indicated that targeting Prp19 may potentiate pro-apoptotic effect of chemotherapeutic agents on HCC.
