Abstract
SPTBN2 is a protein-coding gene that is closely related to the development of malignant tumors. However, its prognostic value and biological function in pan-cancer, especially pancreatic cancer (PAAD), have not been reported. In the present study, a novel exploration of the value and potential mechanism of SPTBN2 in PAAD was conducted using multi-omics in the background of pan-cancer. Via various database analysis, up-regulated expression of SPTBN2 was detected in most of the tumor tissues examined. Overexpression of SPTBN2 in PAAD and kidney renal clear cell cancer patients potentially affected overall survival, disease-specific survival, and progression-free interval. In PAAD, SPTBN2 can be used as an independent factor affecting prognosis. Mutations and amplification of SPTBN2 were detected, with abnormal methylation of SPTBN2 affecting its expression and the survival outcome of PAAD patients. Immunoassay results demonstrate that SPTBN2 was a potential biomarker for predicting therapeutic response in PAAD, and may influence the immunotherapy efficacy of PAAD by regulating levels of CD8 + T cells and neutrophil infiltration. Results from an enrichment analysis indicated that SPTBN2 may regulate the development of PAAD via immune pathways. Thus, SPTBN2 is a potential prognostic biomarker and immunotherapy target based on its crucial role in the development of PAAD.

Abstract
BACKGROUND Hepatocellular carcinoma carries a poor prognosis and poses a serious threat to global health. Currently, there are few potential prognostic biomarkers available for the prognosis of hepatocellular carcinoma. METHODS This pilot study used 4D label-free quantitative proteomics to compare the proteomes of hepatocellular carcinoma and adjacent non-tumor tissue. A total of 66,075 peptides, 6363 identified proteins, and 772 differentially expressed proteins were identified in specimens from three hepatocellular carcinoma patients. Through functional enrichment analysis of differentially expressed proteins by Gene Ontology, KEGG pathway, and protein domain, we identified proteins with similar functions. RESULTS Twelve differentially expressed proteins (RPL17, RPL27, RPL27A, RPS5, RPS16, RSL1D1, DDX18, RRP12, TARS2, YARS2, MARS2, and NARS1) were selected for identification and validation by parallel reaction monitoring. Subsequent Western blotting confirmed overexpression of RPL27, RPS16, and TARS2 in hepatocellular carcinoma compared to non-tumor tissue in 16 pairs of clinical samples. Analysis of The Cancer Genome Atlas datasets associated the increased expression of these proteins with poor prognosis. Tissue microarray revealed a negative association between high expression of RPL27 and TARS2 and the prognosis of hepatocellular carcinoma patients, although RPS16 was not significant. CONCLUSIONS These data suggest that RPL27 and TARS2 play an important role in hepatocellular carcinoma progression and may be potential prognostic biomarkers of overall survival in hepatocellular carcinoma patients.

Abstract
Mesenchymal stem cells (MSCs) have tumor-homing ability and play critical roles in tumor treatment, but their dual influences on tumor progression limit their therapeutic applications. Exosomes derived from MSCs (MSC-exosomes) exhibit great potential in targeted tumor treatment due to their advantages of high stability, low immunogenicity, good biocompatibility, long circulation time and homing characteristics. Furthermore, the artificial modification of MSC-exosomes could amplify their advantages and their inhibitory effect on tumors and could overcome the limit of tumor-promoting effect. In this review, we summarize the latest therapeutic strategies involving artificially modified MSC-exosomes in tumor treatment, including employing these exosomes as nanomaterials to carry noncoding RNAs or their inhibitors and anticancer drugs, and genetic engineering modification of MSC-exosomes. We also discuss the feasibility of utilizing artificially modified MSC-exosomes as an emerging cell-free method for tumor treatment and related challenges.

Abstract
RPL27 is linked to the development of various diseases including malignant tumors. RPL27 may play an oncogenic function in hepatocellular carcinoma (HCC), but this is unknown. So, the aim of this study was to investigate how the human liver cancer cell lines SNU449 and HepG2 responded to RPL27 knockdown in terms of proliferation and apoptosis. SNU449 and HepG2 were cultured and infected with shCon and shRPL27 lentiviral particles to induce RPL27 knockdown, and then RPL27 expression was detected using qPCR and Western blot. Cell proliferation was measured using CCK8, cell cloning, cell scraping, and transwell migration and invasion, while apoptosis was measured using flow cytometry (FCM). The qPCR revealed that mRNA expression of RPL27 decreased after knocking down RPL27 in cells. The CCK8 and cell cloning assay confirmed that knocking down RPL27 significantly reduced cell viability. The cell scratch assay and transwell assays showed that the proliferation rate decreased after knocking down RPL27. A substantial increase in apoptotic cells was discovered by FCM. According to WB, RPL27 knockdown increased the expression of Bax and Caspase-3 while decreasing the expression of bcl-2. The findings showed that RPL27 knockdown inhibited cell proliferation in SNU449 and HepG2 via inducing apoptosis, proving that RPL27 is a novel gene linked with HCC and is crucial for both proliferation and apoptosis. These outcomes imply that RPL27 may be a potential target for liver cancer diagnosis and therapy.

Abstract
BACKGROUND The aim of this study was to evaluate the risk factors of early biliary complications (EBC) after liver transplantation (LT) and seek effective treatments based on our single-center experience. METHODS A total of 124 adult patients were divided into a non-EBC group and EBC group. EBC usually accounts for biliary leakage, biliary stricture, biliary stones, sphincter of Oddi dysfunction, and transient jaundice within 3 months after LT. Statistical analysis including logistic regression was performed to determine EBC risk factors. All procedures complied with the Helsinki Congress and the Declaration of Istanbul. RESULTS Non-EBC (n = 95) and EBC (n = 29) were finally compared, which had no difference in their general characteristics. EBC occurred in 29 patients (26.92%): 1 biliary hemorrhage (3.45%), 7 biliary leakage (24.13%), and 16 biliary stricture (55.18%), and 5 others (17.24%). Of all EBC patients, endoscopic retrograde cholangiopancreatography (68.96%) was higher used to deal with complications than conservative treatment (10.35%), percutaneous transhepatic cholangial drainage (17.24%), and surgical treatment (3.45%). On univariate analyses, risk factors for EBC were bilirubin (P = .014), warm ischemia time (WIT) (P = .020), second WIT (P = .042), and operative time (OT) (P = .033). On multivariate analysis, independent risk factors for BC were WIT (P = .011) and OT (P = .049). CONCLUSIONS The presence of WIT and OT were the independent risk factors for the development of EBC. In addition, we also confirmed that endoscopic retrograde cholangiopancreatography was beneficial and safe in the management of EBC after LT.

Abstract
Background Liver ischemia reperfusion (I/R) injury is a common pathophysiological process in many clinical settings. Carvacrol, a food additive commonly used in essential oils, has displayed antimicrobials, antitumor and antidepressant-like activities. In the present study, we investigated the protective effects of carvacrol on I/R injury in the Wistar rat livers and an in vitro hypoxia/restoration (H/R) model. Methods The hepatoportal vein, hepatic arterial and hepatic duct of Wistar rats were isolated and clamped for 30 min, followed by a 2 h reperfusion. Buffalo rat liver (BRL) cells were incubated under hypoxia for 4 h, followed normoxic conditions for 10 h to establish the H/R model in vitro. Liver injury was evaluated by measuring serum levels of alanine aminotransferase (ALT) and aspatate aminotransferase (AST), and hepatic levels of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and malondiadehyde (MDA), and hepatic histology and TUNEL staining. MTT assay, flow cytometric analysis and Hoechst 33258 staining were used to evaluate the proliferation and apoptosis of BRL cells in vitro. Protein expression was examined by Western Blot analysis. Results Carvacrol protected against I/R-induced liver damage, evidenced by significantly reducing the serum levels of ALT and AST, histological alterations and apoptosis of liver cells in I/R rats. Carvacrol exhibited anti-oxidative activity in the I/R rats, reflected by significantly reducing the activity of SOD and the content of MDA, and restoring the activity of CAT and the content of GSH, in I/R rats. In the in vitro assays, carvacrol restored the viability and inhibited the apoptosis of BRL cells, which were subjected to a mimic I/R injury induced by hypoxia. In the investigation on molecular mechanisms, carvacrol downregulated the expression of Bax and upregulated the expression of Bcl-2, thus inhibited the activation of caspase-3. Carvacrol was also shown to enhance the phosphorylation of Akt. Conclusion The results suggest that carvacrol could alleviate I/R-induced liver injury by its anti-oxidative and anti-apoptotic activities, and warrant a further investigation for using carvacrol to protect I/R injury in clinic.

Abstract
OBJECTIVES Genome-wide association studies (GWAS) have shown that Zbed3 is associated with T2DM. To date, no report has demonstrated a relationship between Zbed3 and insulin resistance in humans, however. The purpose of this study was to determine whether the Zbed3 protein is secreted and identify any associations between Zbed3 and insulin resistance in cross-sectional and interventional studies. METHODS We found that Zbed3 protein was secreted in an in vitro secretion study. Plasma Zbed3 levels were determined in an ELISA and were compared with various parameters related to insulin resistance in subjects with NGT, IGT and nT2DM. EHC was performed in healthy subjects. Real-time PCR and Western blotting were used to assess the mRNA and protein expression of Zbed3. RESULTS Zbed3 was detected in an analysis of in vitro secretion in both conditioned medium and lysates of HEK-293T cells transfected with an overexpressed vector. In a clinical study, there were significantly higher levels of circulating Zbed3 in IGT and nT2DM relative to NGT. Zbed3 levels were positively correlated with BMI, WHR, FAT%, blood pressure, FBG, TG, HbA1c, FIns and HOMA-IR and inversely correlated with HDL-C. Increasing levels of Zbed3 were independently associated with IGT and T2DM. Zbed3 mRNA and protein in muscle and fat were significantly elevated in both db/db mice and T2DM patients. Moreover, there was a concentration-dependent effect of glucose on Zbed3 release, whereas insulin exhibited an inhibitory effect on Zbed3 levels. Zbed3 suppressed insulin-induced IR and Akt phosphorylation. CONCLUSIONS These results suggest that the Zbed3 protein may be a cytokine associated with insulin resistance in humans that is influenced by glucose and insulin levels.

Abstract
OBJECTIVE To explore the regularity of bone development and metabolism in childhood. METHODS A survey was made to collect and analyze the data on bone biochemistry, the density of lumbar vertebrae and the X-ray examination of calcaneus in 224 healthy children aged 3-15 years in the urban area of Chengdu. RESULTS Comparative analysis of serum and urine calcium and phosphate concentrations showed no significant difference between the age groups. The serum alkaline phosphatase (ALP) and bone alkaline phosphatase (BALP) were found to increase with age and reach their peak values in children aged 7-12 years, and their values were significantly higher than that of adults (P < 0.05). The density of lumbar vertebrae and the trabecular bone of calcanesus also developed with age. CONCLUSION The measurements of the bone biochemistry, bone density and the trabecular bone of calcaneus which reflect the bone development and metabolism have their special regularity in childhood. The criteria in use for adulthood is not fit for the evaluation in childhood. The data obtained can be used in clinical diagnosis and treatment of the bone metabolic diseases of children.
