RESUMEN

BACKGROUND Laparoscopic pancreatoduodenectomy (LPD) is a complicated procedure accompanied with high morbidity. Hybrid LPD is usually used as an alternative/transitional approach. This study aimed to prove whether the hybrid procedure is a safe procedure during a surgeon's learning curve of LPD. MATERIAL AND METHODS There were 48 hybrid LPD patients and 62 TLPD patients selected from January 2016 to December 2018; their demographics, surgical outcomes, and oncological data were retrospectively collected. Patient follow-up for the study continued until February 2020. RESULTS Patient demographics and baseline parameters were well balanced between the 2 groups. Intraoperative conditions, overall operation time was shorter for TLPD compared to hybrid LPD (407.79 minutes versus 453.29 minutes, respectively; P=0.035) and blood loss was less in TLPD patients compared to hybrid LPD patients (100.00 mL versus 300.00 mL, respectively; P<0.001). There was no difference in transfusion rates between the 2 groups (hybrid LPD 16.7% versus TLPD 4.8%; P=0.084). Postoperative outcomes and intensive care unit (ICU) stay was longer in the hybrid LPD patient group (hybrid LPD 1-day versus TLPD 0-day, P=0.002) and postoperative hospital stay was similar between the 2 groups (P=0.503). Reoperation rates, in-hospital, 30-day mortality, and 90-day mortality rates were comparable between the 2 groups (P=0.276, 1.000, 1.000, 0.884, respectively). Surgical site infection, bile leak, Clavien-Dindo classification (CDC) ≥3, delayed gastric emptying, grade B/C postoperative pancreatic fistulae, and grade B/C post pancreatectomy hemorrhage were not different between the 2 groups (P=0.526, 0.463, 0.220, 0.089, 0.165, 0.757, respectively). The tumor size, margin status, lymph nodes harvested, and metastasis were similar in the 2 groups (P=0.767, 0.438, 0.414, 0.424, respectively). In addition, the median overall survival rates were comparable between the 2 groups (hybrid LPD 29.0 months versus TLPD 30.0 months, P=0.996) as were the progression-free survival rates (hybrid LPD 11.0 months versus TLPD 12.0 months, P=0.373) CONCLUSIONS Hybrid LPD was comparable to TLPD. Hybrid LPD could be performed safely when some surgeons first started LPD (during the operative learning curve), while for skilled surgeons, TLPD could be applied initially.

RESUMEN

INTRODUCTION AND OBJECTIVES: Laparoscopic splenectomy (LS) is a supportive intervention for cirrhotic patients. However, its efficacy for patients with cirrhotic portal hypertension (CPH) still needs clarification. Studies indicated YKL-40 might be effective targets for treatment of splenomegaly, however deeper insights are unclear. The aim of this study was to investigate the effect of LS on the formation of portal vein thrombosis (PVT) and serum levels of a fibrosis marker, YKL-40, in patients with CPH. MATERIALS AND METHODS: A total of 80 patients who underwent LS and 30 healthy controls were investigated in this study. Serum levels of YKL-40 were measured by enzyme-linked immunosorbent assay (ELISA). Demographic characteristics including age and gender were recorded. Clinicopathological and laboratory examinations included the severity of esophageal varices and the presence of viral hepatitis. The liver function was assessed according to the Child-Pugh classification. The incidence of PVT before and after operation was also monitored. RESULTS: Serum YKL-40 was significantly increased in CPH patients, and was associated with Child-Pugh score and HBV infection. Furthermore, elderly patients had an increased risk for postoperative PVT. Higher serum YKL-40 was observed in patients with thrombus at postoperative 7, 14 and 21 days than those without thrombus. CONCLUSIONS: LS could reduce serum YKL-40 levels and PVT progression and was a useful treatment for patients <40 years of age with CPH.

RESUMEN

BACKGROUND: The manipulation of immunosuppression therapy remains challenging in patients who develop infectious diseases or multiple organ dysfunction after liver transplantation. We evaluated the outcomes of delayed introduction of immunosuppression in the patients after liver transplantation under immune monitoring with ImmuKnow assay. METHODS: From March 2009 to February 2014, 225 consecutive liver recipients in our institute were included. The delayed administration of immunosuppressive regimens was attempted in 11 liver recipients with multiple severe comorbidities. RESULTS: The median duration of non-immunosuppression was 12 days (range 5-58). Due to the infectious complications, the serial ImmuKnow assay showed a significantly low ATP level of 64±35 ng/mL in the early period after transplantation. With the development of comorbidities, the ImmuKnow value significantly increased. However, the acute allograft rejection developed when a continuous distinct elevation of both ATP and glutamyltranspeptidase levels was detected. The average ATP level measured just before the development of acute rejection was 271±115 ng/mL. CONCLUSIONS: The delayed introduction of immunosuppressive regimens is safe and effective in management of critically ill patients after liver transplantation. The serial ImmuKnow assay could provide a reliable depiction of the dynamics of functional immunity throughout the clinical course of a given patient.

RESUMEN

OBJECTIVE: To explore the clinical efficacies of different surgical strategies for patients with advanced pancreatic carinoma. METHODS: Retrospective analyses were conducted for the clinical data of 223 advanced pancreatic carinoma patients between January 2009 and December 2013 according to the inclusion criteria. And, according to different surgical strategies, they were divided into seed group (n = 49), radio frequency ablation group (n = 51), radiotherapy group (n = 17) and control group (n = 106). The general data, postoperative complications and follow-up profiles between 4 groups were statistically analyzed. RESULTS: The general profiles between four groups were not statistically significant (P > 0.05). There was no mortality. The postoperative complication rate was the highest at 43% (21/49) in seed group. However all complications were of Clavien grade II. The follow-up endpoint was until March 2014. The median follow-up period was 7 (1-52) months. The overall follow-up rate was 88.3% (197/223). And their survival rates of one month, half a year, one year and two years were 95.9%, 53.7%, 19.1% and 7.3% respectively. The average survival time was (9.6 ± 0.3) months. In seed group, the rates were 97.7%, 61.9%, 27.7% and 13.2% respectively. The average survival time was (12.9 ± 1.1) months. In radio frequency ablation group, the rates 88.9%, 54.9%, 22.9% and 7.6% respectively. The average survival time was (9.6 ± 0.9) months. In radiotherapy group, the rates were 93.7%, 56.2%, 18.7% and 6.2% respectively. The average survival time was (8.6 ± 1.4) months. In control group, the rates were 97.8%, 48.9%, 13.8% and 5.4% respectively. The average survival time was (8.5 ± 0.5) months. The survival curves of seed, radio frequency ablation and radiotherapy groups were compared separately with that of control group. The Log-rank test results suggested that the survival rate and mean survival time of seed group were higher than those of control group (P < 0.05). However the radio frequency ablation and radiotherapy groups had no significant difference with control group. CONCLUSIONS: The advanced pancreatic carinoma patients have poor outcomes with a short survival time. The intraoperative implantation of seeds is effective for advanced pancreatic cancer patients, but it also has a high incidence of postoperative complications. Radio frequency ablation and intraoperative radiotherapy fail to effectively prolong the patient survival time.

RESUMEN

OBJECTIVE: To explore the application value of computer-assisted preoperative planning of hilar cholangiocarcinoma. METHODS: Retrospective analyses were conducted for the clinical data of 47 patients with hilar cholangiocarcinoma undergoing radical resection plus hemihepatectomy from January to December 2013. According to whether computer-assisted preoperative planning was used, they were divided two groups of computer-assisted surgical planning (CASP) and without computer-assisted surgical planning (WCASP). Then we analyzed the data including preoperative examinations, preoperative planning, intraoperative findings and postoperative complications. RESULTS: There were 31 cases of hilar vascular invasion by tumor. Among 29 cases of CASP, left hepatic artery originated from left gastric artery (n = 6), right posterior bile duct drained into left hepatic bile duct (n = 1) and right posterior bile duct run into common hepatic bile duct (n = 2). The mean operative duration of CASP was (6.5 ± 1.3) h and the mean volume of intraoperative bleeding (672.0 ± 214.3) ml; while the mean operative duration of WCASP was (7.9 ± 2.9) h and the mean volume of intraoperative bleeding (870.0 ± 330.1) ml. By statistical analysis, the inter-group differences of mean operative duration had statistical difference (P = 0.028) and the inter-group differences of mean volume of intraoperative bleeding had statistical difference (P = 0.016). The ratio of first negative test in group CASP was higher than that of group WCASP and the inter-group differences had statistical significance (P = 0.043). But the inter-group rate of postoperative complications had no significant difference (P = 0.419). CONCLUSIONS: The computer-assisted surgical planning system provides accurate information so that an optimal surgical protocol may be designed by surgeons. And it has great application values in preoperative surgical planning for hilar cholangiocarcinoma and enjoys wide prospects in precise liver surgery.

RESUMEN

OBJECTIVE: To describe the clinicopathological characteristics and prognosis of intrahepatic biliary cystic tumor (IBCT) and compare the difference betwwen male and female patients. METHODS: 11 male and 45 female patients with histological confirmed IBCT from January 2003 to April 2014 were envolved. clinical characteristics, laboratory examination, radiological features, treatment method and prognosis were analyzed. RESULTS: The mean age of male patients with IBCT was significantly older than that of female patients (54.9±10.1 years vs 46.2±12.9 years, P=0.041). There were no significant differences in radiological features between male and female patients except for mural nodules (10/11 vs 15/45, P=0.001). Intrahepatic biliary cystadenocarcinoma (IBC) was more common in male patients than female patients (8/11 vs 16/45, P=0.041). Male patients had worse prognosis than female patients (P=0.014). 1-year, 3-year, and 5-year survival of male patients was 90.9%,45.5%,30.3%, respectively. However, 1-year, 3-year, and 5-year survival of female patients was 94.8%,82.7%,78.6%. CONCLUSIONS: Male patients had low incidence of IBCT, and were more common for IBC. Even with complete resection, the long-term survival was still poor, close follow-up were recommended especially for male patients.

RESUMEN

OBJECTIVE: To describe the treatment and prognosis of solid pseudopapillary neoplasms (SPN) with metastases or recurrence. METHODS: The clinical date of 24 patients with histological confirmed SPN with metastases or recurrence from January 2000 to April 2014 were retrospectively analyzed. There were 22 females and 2 males, with mean age of (36 ± 16) years. Fourteen patients had local recurrence or metastasis after surgery, with a mean time of recurrence (44 ± 29) months. Ten patients were defined SPN with distant metastasis at first admission. Nineteen patients underwent surgical resection, among them, 11 patients received complete resection. Nine cases underwent chemotherapy. Kaplan-Meier method was used to identify prognostic factors. RESULTS: Twenty-four patients were followed-up, 9 patients died. Median survival time was 47 months, and 1-year, 3-year, and 5-year survival was 91.7%, 65.1%, 49.6%, respectively. Age (χ(2) = 6.858, P = 0.009), primary tumor diameter (χ(2) = 4.322, P = 0.038), extrahepatic metastasis (χ(2) = 5.279, P = 0.022) and complete resection of metastases and recurrence (χ(2) = 4.666, P = 0.031) were important prognostic factors for survival (P < 0.05). CONCLUSIONS: For SPN with metastases or recurrence, good prognosis can also obtain after complete resection. Age, primary tumor diameter, extrahepatic metastasis and complete resection of metastases and recurrence are influence factors on prognosis of patients.

RESUMEN

In comparison with the out-of-plane vibrations of annular plates, far less attention has been paid to the in-plane vibrations which may also play a vital important role in affecting the sound radiation from and power flows in a built-up structure. In this investigation, a generalized Fourier series method is proposed for the in-plane vibration analysis of annular plates with arbitrary boundary conditions along each of its edges. Regardless of the boundary conditions, the in-plane displacement fields are invariantly expressed as a new form of trigonometric series expansions with a drastically improved convergence as compared with the conventional Fourier series. All the unknown expansion coefficients are treated as the generalized coordinates and determined using the Rayleigh-Ritz technique. Unlike most of the existing studies, the presented method can be readily and universally applied to a wide spectrum of in-plane vibration problems involving different boundary conditions, varying material, and geometric properties with no need of modifying the basic functions or adapting solution procedures. Several numerical examples are presented to demonstrate the effectiveness and reliability of the current solution for predicting the in-plane vibration characteristics of annular plates subjected to different boundary conditions.

RESUMEN

Nonalcoholic fatty liver disease (NAFLD) is a serious disease. There are no specific drugs for it, in part because of the lack of effective models to aid drug development. However, it has been shown that three-dimensional organoid culture systems can reproduce the organ structure and maintain the gene expression profile of the original tissue. Therefore, we aimed to construct NAFLD models from liver organoids for pharmacological and mechanism studies. We successfully observed morphological changes in normal liver tissue in mouse liver organoids with positive albumin (ALB) expression and potential for differentiation toward hepatocyte-like cells. The mRNA expression of the hepatocyte markers ALB and hepatocyte nuclear factor 4 alpha increased after liver organoid differentiation. We observed free fatty acid (FFA)-induced lipid accumulation in organoids with significant increases in alanine aminotransferase, aspartate aminotransferase, total bilirubin, and triglyceride levels. Moreover, FFA-induced inflammatory cytokines (interleukin-6, tumor necrosis factor-α, and nitric oxide) and fibrosis indicators (collagen type I α1 and laminin α1) were also increased. In addition, RNA sequencing results showed that the expression of key genes [nucleotide oligomerization domain-like receptor (NLR) family apoptosis inhibitory protein, interferon regulatory factor (IRF) 3, and IRF7] involved in NAFLD metabolic abnormalities and insulin resistance in the NLR signaling pathway was altered after FFA induction of the liver organoids. Finally, we found that JC2-11 and lanifibranor limited the FFA-induced increase in oil-red lipid droplets, liver damage, inflammation, and liver fibrosis. In conclusion, tissue structure, gene expression, and the response of mouse liver organoids to drugs can partially mimic in vivo liver tissue. Liver organoids can successfully construct NAFLD models for drug discovery research.

RESUMEN

Persistent inflammation and disrupted immunoregulation are critical factors in impeding diabetic wound healing. While immunoregulatory hydrogel dressings hold significant promise for clinical applications in diabetic wound healing, the current application often demands intricate interventions and high-cost treatments involving cytokines and cell therapies. The development of single component immunoregulatory hydrogels remains a complex challenge. To address this issue, an active peptide hydrogel with immunoregulatory properties targeting the TLR4/NF-kB pathway, aiming to promote rapid diabetic wound healing, is engineered. The hydrogel sequence comprises naphthalene derivative, phenylalanine, and glycine to modulate hydrophilic/hydrophobic characteristics. The amino group on arginine contributes to tissue adhesion and regulation of intermolecular forces, ultimately yielding stable gels. The results underscore the formation of the peptide hydrogel (NFA) via the physical crosslinking of self-assembled nanofibers in water, thereby affording both excellent injectability and tissue adhesion. Notably, NFA demonstrates significant potential in promoting wound healing in a mouse model with full-thickness wounds by regulating macrophage responses in the inflammatory microenvironment through the TLR4/NF-kB pathway.

RESUMEN

OBJECTIVE: To explore the long-term postoperative complications of Warshaw operation for distal pancreatectomy with preservation of spleen. METHODS: Retrospectively analyzed the clinical data of distal pancreatectomy on 84 cases between January 2006 and January 2012. Among them, 35 patients underwent Warshaw operation for distal pancreatectomy with preservation of spleen and another 23 had distal pancreatectomy with Kimura operation. All of them were followed up. RESULTS: All procedures were successful. There was no perioperative mortality. During the follow-up period, 2 patients undergoing Warshaw operation were lost. The median follow-up period was 2.6 years (range: 0.75-6.75). Twenty-six patients with the recent neuroimaging data showed: 5 patients were diagnosed of splenic infarction and the incidence rate was 19.2% (5/26) and 6 with gastric varices and the incidence rate was 23.1% (6/26). But none of them developed gastrointestinal hemorrhage or splenic abscess. CONCLUSION: The Warshaw operation for distal pancreatectomy with preservation of spleen may increase the risk of long-term postoperative complications so that its operative indication must be strictly mastered.

RESUMEN

BACKGROUND: Datura Metel L. has been used to treat psoriasis in China for a long time. The effect of extracts from Datura Metel L. for Psoriasis has not been previously confirmed. This study aimed to evaluate the efficacy of extracts from Datura Metel L. for patients with psoriasis. METHODS: PubMed, Cochrane Library, Embase, and other databases were searched from database inception until to September 1, 2021. A quality assessment and data extraction were performed by 2 independent reviews. We used a random-effects meta-analysis model to estimate the pooled curative effect, pooled odds ratio (OR), and 95% confidence intervals. RESULTS: Nine studies were included in Meta-analysis, including a total number of 1778 patients with psoriasis. The case cure rate of Datura Metel L. intravenous therapy was 0.48 (95% CI: 0.33, 0.62) and of Datura Metel L. oral therapy was 0.42 (95% CI: 0.17, 0.68), respectively. The case effective rate of Datura Metel L. intravenous therapy was 0.91 (95% CI: 0.84, 0.97) and of Datura Metel L. oral therapy was 0.94 (95% CI: 0.88, 0.99), respectively. CONCLUSIONS: The extracts from Datura Metel L. showed the potential to treat psoriasis, and intravenous therapy might be a promising treatment to cure psoriasis, which is likely affected by selection and publication bias, still need more high quality clinical studies.

RESUMEN

Background: Liver cancer, especially hepatocellular carcinoma (HCC), remains a significant global health challenge. Traditional prognostic indicators for HCC often fall short in providing comprehensive insights for individualized treatment. The integration of genomics and radiomics offers a promising avenue for enhancing the precision of HCC diagnosis and prognosis. Methods: From the Cancer Genome Atlas (TCGA) database, we categorized mRNA of HCC patients by Forkhead Box M1 (FOXM1) expression and performed univariate and multivariate studies to pinpoint autonomous HCC risk factors. We deployed subgroup, correlation, and interaction analyses to probe FOXM1's link with clinicopathological elements. The connection between FOXM1 and immune cells was evaluated using the CIBERSORTx database. The functions of FOXM1 were investigated through analyses of Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG). After filtering through TCGA and the Cancer Imaging Archive (TCIA) database, we employed dual-region computed tomography (CT) radiomics technology to noninvasively predict the mRNA expression of FOXM1 in HCC tissues. Radiomic features were extracted from both tumoral and peritumoral regions, and a radiomics score (RS) was derived. The performance and robustness of the constructed models were evaluated using 10-fold cross-validation. A radiomics nomogram was developed by incorporating RS and clinical variables from the TCGA database. The models' discriminative abilities were assessed using metrics such as the area under the curve (AUC) of the receiver operating characteristic curves (ROC) and precision-recall (PR) curves. Results: Our findings emphasized the overexpression of FOXM1 as a determinant of poor prognosis in HCC and illustrated its impact on immune cell infiltration. After selecting arterial phase CT, we chose 7 whole-tumor features and 3 features covering both the tumor and its surroundings to create WT and WP models for FOXM1 prediction. The WT model showed strong predictive capabilities for FOXM1 expression by PR curve. Conversely, the WP model did not demonstrate the good predictive ability. In our study, the radiomics score (RS) was derived from whole-tumor regions on CT images. The RS was significantly associated with FOXM1 expression, with an AUC of 0.918 in the training cohort and 0.837 in the validation cohort. Furthermore, the RS was correlated with oxidative stress genes and was integrated with clinical variables to develop a nomogram, which demonstrated good calibration and discrimination in predicting 12-, 36-, and 60-month survival probabilities. Additionally, bioinformatics analysis revealed FOXM1's potential role in shaping the immune microenvironment, with its expression linked to immune cell infiltration. Conclusion: This study highlights the potential of integrating FOXM1 expression and radiomics in understanding HCC's complexity. Our approach offers a new perspective in utilizing radiomics for non-invasive tumor characterization and suggests its potential in providing insights into molecular profiles. Further research is needed to validate these findings and explore their clinical implications in HCC management.

RESUMEN

Background: Circular RNAs (circRNAs) are becoming vital biomarkers and therapeutic targets for malignant tumors due to their high stability and specificity in tissues. However, biological functions of circRNAs in hepatocellular carcinoma (HCC) are still not well studied. Methods: Gene Expression Omnibus (GEO) database and qRT-PCR were used to evaluate expression of circROBO1 (hsa_circ_0066568) in HCC tissues and cell lines. CCK-8, colony formation, EdU staining, flow cytometry for cell cycle analysis, and xenograft model assays were performed to detect the circROBO1 function in vitro and in vivo. RNA pull-down, RNA immunoprecipitation (RIP), and Luciferase reporter assays were used to investigate the relationship among circROBO1, miR-130a-5p, and CCNT2. More importantly, we developed nanoparticles made from poly lactic-co-glycolic acid (PLGA) and polyethylene glycol (PEG) chains as the delivery system of si-circROBO1 and then applied them to HCC in vitro and in mice. Results: circROBO1 was obviously upregulated in HCC tissues and cell lines, and elevated circROBO1 was closely correlated with worse prognosis for HCC patients. Functionally, knocking down circROBO1 significantly suppressed HCC cells growth in vitro and in mice. Mechanistically, circROBO1 acted as a competing endogenous RNA to downregulate miR-130a-5p, leading to CCNT2 expression upregulation. Furthermore, miR-130a-5p mimic or CCNT2 knockdown reversed the role of circROBO1 overexpression on HCC cells, which demonstrated that circROBO1 promoted HCC development via miR-130a-5p/CCNT2 axis. In addition, we developed nanoparticles loaded with si-circROBO1, named as PLGA-PEG (si-circROBO1) NPs, which significantly prevented the proliferation of HCC cells, and did not exhibit apparent toxicity to major organs in vivo. Conclusion: Our findings firstly demonstrate that circROBO1 overexpression promotes HCC progression by regulating miR-130a-5p/CCNT2 axis, which may serve as an effective nanotherapeutic target for HCC treatment.

OBJECTIVE: To explore the clinical application of laparoscopic distal pancreatectomy (LDP) in hepatobiliary operations. METHODS: The clinical data of LDP from 25 cases from June 2008 to December 2011 were retrospectively analyzed. Among them, 9 patients underwent LDP with excision of spleen while another 16 patients had LDP with preservation of spleen. And during the same period, 42 patients undergoing open distal pancreatectomy were selected into the control group. And the patient data of two groups were compared. RESULTS: All of them underwent successfully LDP. Among 16 patients with preservation of spleen, 11 patients undergone the Kimura procedure while another 5 undergone the Warshaw operation. The operative duration was (4.5 ± 1.2) hours, volume of blood loss (256 ± 188) ml, length of incision (4.6 ± 0.9) cm, mean time of oral food taking (1.5 ± 0.9) days and mean postoperative hospital stay (7.1 ± 1.9) days. Pathological examinations showed benign tumor (n = 20), malignant tumor (n = 4) and borderline tumor (n = 1). The mean data of LDP group was significantly less than that of open distal pancreatectomy group in terms of anal exsufflation time, length of incision, postoperative hospital stay time and complication rate, etc. (P < 0.05). Four patients were diagnosed of post-LDP pancreatic fistula (3 A level vs 1 B level) and all of them became cured after conservative treatment. There was no mortality. CONCLUSION: As a safe and feasible procedure, LDP is worthy of wider applications.

RESUMEN

OBJECT: With the gradual advancement of laparoscopic technology, surgeries can be successfully performed with the help of laparoscopy increasingly. This study initially explored the difference between laparoscopic right posterior sectionectomy (LRPS) and open right posterior sectionectomy (ORPS)of liver in our center, discussed the effectiveness, benefits and safety of LRPS and introduce some surgical techniques in our center. MATERIALS AND METHODS: We retrospectively analyze 96 cases of liver tumor located in the right posterior lobe of liver in our institution from January 2015 to January 2018. There were 46 cases performed the LRPS surgery and 50 cases performed the ORPS surgery. Through analysis of the perioperative outcomes of these two groups by a case control study, we compare the differences between these two groups. RESULTS: There was no significant difference between the LRPS and ORPS group in demographic and baseline characteristics before surgery. Patients in the LRPS group were significantly superior to ORPS in terms of postoperative liver function recovery, postoperative inflammatory factor level, pain sensation (3.03 ± 0.79 vs 4.58 ± 1.25), abdominal incision length (6.25 ± 2.34 vs 32.15 ± 3.21), carrying abdominal drainage tube time (3.26 ± 0.77 vs 4.83 ± 0.76), recovery of bowel function time (1.6 ± 0.61 VS 3.05 ± 0.85)and postoperative hospital stay (5.73 ± 0.99 vs 7.16 ± 0.95) (P < 0.05). CONCLUSION: Compared with the traditional ORPS, LRPS has the advantages of minor injury, faster recovery and mild inflammatory reaction. The LRPS is safe and feasible, and it should be gradually promoted in clinical practice.

RESUMEN

Background: A large number of cancer-related deaths in the world can be attributed to liver hepatocellular carcinoma (LIHC). The purpose of this study is to explore protein tyrosine phosphatase type IV A member 3 (PTP4A3/PRL-3) as a new and reliable biomarker to predict the prognosis of LIHC and determine the potential therapeutic targets or drugs that can be used for treating LIHC. Methods: We included three LIHC datasets with clinical information and expression profiles from public databases. The expression level of PTP4A3 was analyzed, and based on the results, the samples were divided into high- and low-expression groups. The Kaplan-Meier survival analysis method was used to determine the relationship between PTP4A3 and prognosis. The enrichment differences among the functional pathways associated with the high- and low-expression groups were determined using the gene set enrichment analysis (GSEA) method. Five methods were used to determine the differences among the tumor microenvironment in the low- and high-expression groups. The sensitivity of the low- and high-expression groups toward different drug treatment methods was predicted by analyzing the Tumor Immune Dysfunction and Exclusion (TIDE) scores and determining the biochemical half-maximal inhibitory concentration (IC50). Results: The expression levels of the LIHC and adjacent samples were analyzed, and it was observed that the expression level of PTP4A3 in tumor tissue was significantly higher than the expression level of the same gene in the adjacent samples. It was also inferred that it might be a cancer-promoting gene. It was concluded that high-expression results in a significantly poor prognosis. The high-expression group was significantly enriched in the tumor-related pathways, such as the PI3K-AKT signaling pathway. In addition, the results obtained by conducting immune infiltration analysis revealed a significant positive correlation between some immune scores and the gene PTP4A3. The drug KIN001-135 and gene PTP4A3 were also found to correlate positively with each other. CP466722, Pyrimethamine, AKT inhibitor VIII, Embelin, Cisplatin, QS11, Bexarotene, and Midostaurin negatively correlated with PTP4A3 associated with the three datasets. Moreover, the drugs Cisplatin, QS11, Midostaurin, and CP466722 were more sensitive toward the high-expression group than the low PTP4A3 expression group. Significant differences were observed in these cases. Conclusion: PTP4A3/PRL-3 is potentially associated with the progression, metastasis, and invasion of LIHC. The prognosis of LIHC patients is negatively impacted by the high-expression levels of the gene. The results indicate that PTP4A3/PRL-3 is an important prognostic factor for LIHC and is a new potential prognostic detection target. The discovery of the 8 drugs that were negatively associated with PTP4A3 provided a new direction that can be developed in the future for the treatment of LIHC.

RESUMEN

BACKGROUND: Oxidative stress, cell pyroptosis and inflammation are considered as important pathogenic factors for ulcerative colitis (UC) development, and the traditional anti-alcoholism drug disulfiram (DSF) has recently been reported to exert its regulating effects on all the above cellular functions, which makes DSF as ideal therapeutic agent for UC treatment, but this issue has not been fully studied. METHODS: Dextran sulfate sodium (DSS)-induced animal models in C57BL/6J mice and lipopolysaccharide (LPS)-induced cellular models in colonic cell lines (HT-29 and Caco-2) for UC were respectively established. Cytokine secretion was determined by ELISA. Cell viability and proliferation were evaluated by MTT assay and EdU assay. Real-Time qPCR, Western Blot, immunofluorescent staining assay and immunohistochemistry (IHC) were employed to evaluate gene expressions. The correlations of the genes in the clinical tissues were analyzed by using the Pearson Correlation analysis. RESULTS: DSF restrained oxidative stress, pyroptotic cell death and cellular inflammation in UC models in vitro and in vivo, and elimination of Reactive Oxygen Species (ROS) by N-acetyl-l-cysteine (NAC) rescued cell viability in LPS-treated colonic cells (HT-29 and Caco-2). Further experiments suggested that a glycogen synthase kinase-3ß (GSK-3ß)/Nrf2/NLRP3 signaling cascade played critical role in this process. Mechanistically, DSF downregulated GSK-3ß and NLRP3, whereas upregulated Nrf2 in LPS-treated colonic cells. Also, the regulating effects of DSF on Nrf2 and NLRP3 were abrogated by upregulating GSK-3ß. Moreover, upregulation of GSK-3ß abolished the protective effects of DSF on LPS-treated colonic cells. CONCLUSIONS: Taken together, data of this study indicated that DSF restrained oxidative damages-related pyroptotic cell death and inflammation via regulating the GSK-3ß/Nrf2/NLRP3 pathway, leading to the suppression of LPS-induced UC development.

RESUMEN

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) is a fatal malignancy due to the lack of early detection method, therapeutic drug and target. We noticed that the expression of Protein Tyrosine Phosphatase Mitochondria1(PTPMT1) is upregulated in PDAC. However, its role in pancreatic cancer remains unknown. METHODS: We first analyzed the expression of PTPMT1 from 50 PDAC patients. Secondly, the survival proportions of different PTPMT1-expressed patients were analyzed. Then, the role and mechanism of PTPMT1 in PDAC were studied by lentivirus transduction system. RESULTS: PTPMT1 was upregulated in PDAC and patients with high PTPMT1 expression displayed lower overall survival rate. Knockdown of PTPMT1 increased the sensitivity to erastin or RSL3 induced ferroptosis. Mechanically, knockdown of PTPMT1 resulted in upregulated Acyl-CoA Synthetase Long Chain Family Member 4 (ACSL4) and downregulated Solute Carrier Family 7 Member 11 (SLC7A11). In addition, SLC7A11 was upregulated in PDAC tumor tissue and correlated positively with the expression of PTPMT1. However, the expression of ACSL4 was downregulated in PDAC and negatively correlated with the expression of PTPMT1. CONCLUSION: Our study demonstrates that PTPMT1 is upregulated in PDAC and PTPMT1 inhibits ferroptosis by suppressing the expression of ACSL4 and upregulating SLC7A11 in Panc-1 cells, suggesting PTPMT1 might be a potential prognosis biomarker and therapeutic target in PDAC.

RESUMEN

BACKGROUND: Glycolysis caused by hypoxia-induced abnormal activation of hypoxia inducible factor-1α (HIF-1α) in the immune microenvironment promotes the progression of hepatocellular carcinoma (HCC), leading to enhanced drug resistance in cancer cells. Therefore, altering the immunosuppressive microenvironment by imp-roving the hypoxic state is a new goal in improving cancer treatment. AIM: To analyse the role of HIF-1α, which is closely related to tumour proliferation, invasion, metastasis, and angiogenesis, in the proliferation and invasion of liver cancer, and to explore the HIF-1α pathway-mediated anti-cancer mechanism of sirolimus (SRL) combined with Huai Er. METHODS: Previous studies on HCC tissues identified the importance of HIF-1α, glucose transporter 1 (GLUT1), and lactate dehydrogenase A (LDHA) expression. In this study, HepG2 and Huh7 cell lines were treated, under hypoxic and normoxic conditions, with a combination of SRL and Huai Er. The effects on proliferation, invasion, cell cycle, and apoptosis were analysed. Proteomics and genomics techniques were used to analyze the HIF-1α-related signalling pathway during SRL combined with Huai Er treatment and its inhibition of the proliferation of HCC cells. RESULTS: High levels of HIF-1α, LDHA, and GLUT-1 were found in poorly differentiated HCC, with lower patient survival rates. Hypoxia promoted the proliferation of HepG2 and Huh7 cells and weakened the apoptosis and cell cycle blocking effects of the SRL/Huai Er treatment. This was achieved by activation of HIF-1α and glycolysis in HCC, leading to the upregulation of LDHA, GLUT-1, Akt/mammalian target of rapamycin (mTOR), vascular endothelial growth factor (VEGF), and Forkhead box P3 and downregulation of phosphatase and tensin homolog deleted on chromosome ten (PTEN) and p27. The hypoxia-induced activation of HIF-1α showed the greatest attenuation in the SRL/Huai Er (S50 + H8) group compared to the drug treatments alone (P < 0.001). The S50 + H8 treatment significantly downregulated the expression of mTOR and HIF-1α, and significantly reduced the expression of VEGF mRNA. Meanwhile, the combined blocking of mTOR and HIF-1α enhanced the downregulation of Akt/mTOR, HIF-1α, LDHA, and GLUT-1 mRNA and resulted in the downregulation of PTEN, p27, and VEGF mRNA (P < 0.001). CONCLUSION: SRL increases the anti-cancer effect of Huai Er, which reduces the promotion of hypoxia-induced HIF-1α on the Warburg effect by inhibition of the PI3K/Akt/mTOR-HIF-1α and HIF-1α-PTEN signalling pathways in HCC.
