RESUMO

BACKGROUND: While single-incision laparoscopic cholecystectomy (SILC) has gained more popularity in recent years, its application to elderly patients needs further evaluation. Few SILC studies regarded this rapidly growing vulnerable population, and single-incision laparoscopic common bile duct exploration (SILCBDE) was never mentioned. We conducted an observational study of 146 routine SILCBDE to address this issue. METHODS: One hundred forty-six consecutive patients underwent SILCBDE with concomitant cholecystectomies during a period of 6 years (July 2012-June 2016 and July 2018-July 2020). Forty patients with an age of 65 years or older were the study target. Characteristics and operative outcomes were compared with the remaining 106 younger patients by retrospective chart review. The primary outcomes include complications and mortality, while the secondary outcomes contain intraoperative blood loss, operative time, procedural conversions, postoperative length of hospital stay, and bile duct stone recurrence. RESULTS: There was no mortality. The bile duct stone clearance rate was 98.6%. The elderly group had higher American Society of Anesthesiologists (ASA) scores, higher comorbidity rate, higher acute cholangitis rate, lower completion intraoperative cholangiography (IOC) rate, longer operative time, more blood loss, longer postoperative hospital stay (p < .001), longer total hospital stay (p < .001), higher procedural conversion rate (p < .05), higher complication rate (p < .001), and the exclusive open conversion (2.5%). The difference in complications derived from Clavien-Dindo grade I. CONCLUSION: Routine SILCBDE with concomitant cholecystectomy by experienced surgeons is safe and efficacious for elderly patients as for younger patients. Randomized controlled trials are anticipated.

RESUMO

Cancer and depression are closely interrelated, particularly in patients with advanced cancer, who often present with comorbid anxiety and depression for various reasons. Recently, there has been a growing interest in the study of depression in cancer patients, with the aim of assessing the possible triggers, predictors, adverse events, and possible treatment options for depression in several common cancers. The objective of this narrative review is to synthesize the extant literature on the relationship between the occurrence and progression of depression in several common patient categories. The authors conducted a comprehensive review of 75 articles published in PubMed over the past five years. This review was further evaluated in the present paper. Ultimately, it was determined that depression is a prevalent and detrimental phenomenon among cancer patients, particularly those with advanced disease. Consequently, there is a pressing need to prioritize research and interventions aimed at improving the quality of life and psychosocial well-being of cancer patients, including those with advanced disease. The relationship between cancer and depression has been evolving dynamically in recent times. The current research findings indicate a strong association between cancer and depression. However, the direction of causality remains unclear. Focusing on depression in cancer patients may, therefore, be beneficial for these patients.

RESUMO

BACKGROUND: Common bile duct (CBD) stones commonly occur in cholecystectomy cases. The management options include laparoscopic CBD exploration (LCBDE) or endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC). Although ERCP is fully developed, it has complications, and LCBDE is a proven alternative. This study aimed to evaluate the safety and efficacy of these treatments in elderly individuals aged ≥70 years. METHODS: A retrospective study between January 2015 and July 2022 included 160 elderly patients (aged ≥70 years) diagnosed with cholelithiasis and choledocholithiasis. The patients were divided into 1-stage (LCBDE [n = 80]) or 2-stage (ERCP followed by LC [n = 80]) treatment groups. Data collected encompassed comorbidities, symptoms, bile duct clearance, postoperative complications, and long-term outcomes for systematic analysis. RESULTS: This study analyzed 160 patients treated for CBD stones, comparing 1-stage and 2-stage groups. The 1-stage group had more female patients than the 2-stage group (57.5% vs 37.5%, respectively). The 1-stage group had a mean age of 80.55 ± 7.00 years, which was higher than the mean age in the 2-stage group. American Society of Anesthesiologists classification, Charlson Comorbidity Index, and laboratory findings were similar. Pancreatitis and cholangitis occurred after ERCP in the 2-stage group. Stone clearance rates (92.35% [1-stage group] vs 95.00% [2-stage group]) and biliary leakage incidence (7.5% [1-stage group] vs 3.0% [2-stage group]) were similar, as were postoperative complications and long-term recurrence rates (13.0% [1-stage group] vs 12.5% [2-stage group]). CONCLUSION: Our research indicates that both the combination of LCBDE and LC and the sequence of ERCP followed by LC are equally efficient and secure when treating CBD stones in elderly patients. Consequently, the 1-stage procedure may be considered the preferred treatment approach for this demographic.

RESUMO

Regorafenib is a multikinase inhibitor that was approved by the US Food and Drug administration in 2017. Cancer stem cells (CSCs) are a small subset of cancer-initiating cells that are thought to contribute to therapeutic resistance. The forkhead box protein M1 (FOXM1) plays an important role in the regulation of the stemness of CSCs and mediates resistance to chemotherapy. However, the relationship between FOXM1 and regorafenib resistance in liver cancer cells remains unknown. We found that regorafenib-resistant HepG2 clones overexpressed FOXM1 and various markers of CSCs. Patients with hepatocellular carcinoma also exhibited an upregulation of FOXM1 and resistance to regorafenib, which were correlated with a poor survival rate. We identified a close relationship between FOXM1 expression and regorafenib resistance, which was correlated with the survival of patients with hepatocellular carcinoma. Thus, a strategy that antagonizes FOXM1-CD44 signaling would enhance the therapeutic efficacy of regorafenib in these patients.

RESUMO

BACKGROUND: We developed laparoscopic transfistulous bile duct exploration (LTBDE) for Mirizzi syndrome (MS) McSherry type II in September 2011. Then, single-incision LTBDE (SILTBDE) was adopted as a preferred technique since August 2013. This retrospective study aims to analyze the outcome of LTBDE in 7.7 years and to compare SILTBDE with four-incision LTBDE (4ILTBDE). METHODS: Seventeen consecutive patients underwent LTBDE for MS McSherry type II from September 2011 to May 2019. Transfistulous removal of the impacted stone(s), choledochoscopic bile duct exploration, and primary closure of the gallbladder remnant were performed without biliary drainage. RESULTS: The sex ratio is 12:5 (male: female) with an average age of 39.4 ± 10.3 (24-56) years. Ten patients (58.8%) had their diagnoses of MS established by preoperative imaging. According to the Csendes classification, three type II (17.6%), nine type III (52.9%), and five type IV (29.4%) were identified. The operative time was 264.8 ± 60.3 min (156-358 min). The stone clearance rate was 100%. The postoperative hospital stay was 4.7 ± 1.9 (2-10) days. No procedure was converted to an open operation. Two postoperative transient hyperamylasemia (11.8%) and one superficial wound infection (5.9%) occurred and all recovered well under conservative treatment (Clavien-Dindo grade I). During an average 2.2-year follow-up period, no biliary stricture or stone recurrence occurred. No significant difference exists between the SILTBDE and 4ILTBDE groups. Nevertheless, an insignificant trend of shorter postoperative hospital stay was observed in the former. A diagnosis of MS Csendes type IV implicates prolonged total and postoperative hospital stays (p < 0.01). CONCLUSIONS: LTBDE is safe and efficacious for MS McSherry type II. It provides a simple solution for various types of MS and avoids undesirable complications following bilioenteric anastomosis. SILTBDE is comparable to 4ILTBDE for selected patients. Patients with MS Csendes type IV need more time to recover after surgery.

RESUMO

BACKGROUND: Effective prognostic biomarkers and powerful target-therapeutic drugs are needed for improving the treatment of Hepatocellular carcinoma (HCC). OBJECTIVE: This study aimed to evaluate the expression of FOXM1 and Aurora-A and their prognostic value in HCC. METHODS: We determined the differentially expressed genes signature in HCC using the Gene Set Enrichment Analysis (GSEA), and then evaluated the expression of FOXM1 and Aurora-A in TCGA and KMUH cohort. Associations between co-expression of FOXM1 and Aurora-A and clinical variables were calculated. Overall survival (OS) and recurrence-free survival (RFS) were estimated with different FOXM1 and Aurora-A expression status. RESULTS: FOXM1-related gene sets were mostly associated with cell cycle regulation in HCC tissues. We found a positive correlation between the expression of FOXM1 and Aurora-A. Overexpression of FOXM1 and Aurora-A was associated with larger tumor size, advanced stage, higher grade, and double-positive for HBV and HCV. The coordinated overexpression of FOXM1 and Aurora-A was the most significant independent prognostic factor for OS and RFS. Furthermore, the concomitant high expression of FOXM1 and Aurora-A predicted the worst OS of sorafenib-treated patients with HCC. CONCLUSIONS: The co-expression of FOXM1 and Aurora-A could be a reliable biomarker to predict the sorafenib response and prognosis of HCC patients.

RESUMO

AIM: This paper aims to describe an intracorporeal tourniquet method for laparoscopic Pringle maneuver (PM). METHODS: One shortened Foley tube with side-hole on the tip was put into the abdomen. Then, the tail was pulled out through the side-hole to make a loop to encircle porta hepatis for inflow control. RESULT: It is easy to keep the tension by a metallic clip, and when released, the clip can be removed and the loop loosened. CONCLUSION: Therefore, PM could be performed inside the abdomen without special instrument nor extra trocar port. The intracorporeal Pringle maneuver with Huang's loop could be routinely used during laparoscopic liver resection even for a laparoscopic beginner because it is so easily learnt, safe, and effective.

RESUMO

Renal cell carcinoma (RCC) is the third most frequent malignancy within urological oncology. However, the mechanisms responsible for RCC metastasis are still needed further illustration. Our present study revealed that a seven-transmembrane receptor G-protein coupled estrogen receptor (GPER) was highly detected in various RCC cell lines such as ACHN, OS-RC-2 and SW839. The activation of GPER by its specific agonist G-1 significantly promoted the in vitro migration and invasion of ACHN and OS-RC-2 cells. G-1 also up regulated the expression of matrix metalloproteinase-2 (MMP-2) and MMP-9. The inhibitor of MMP-9 (Cat-444278), but not MMP-2 (Sc-204092), abolished G-1 induced cell migration, which suggested that MMP-9 is the key molecule mediating G-1 induced RCC progression. Further, G-1 treatment resulted in phosphorylation of AKT and ERK in RCC cells. PI3K/AKT inhibitor (LY294002), while not ERK inhibitor (PD98059), significantly abolished G-1 induced up regulation of MMP-9 in both AHCN and OS-RC-2 cells. Generally, our data revealed that activation of GPER by its specific agonist G-1 promoted the metastasis of RCC cells through PI3K/AKT/MMP-9 signals, which might be a promising new target for drug discovery of RCC patients.

RESUMO

BACKGROUND: Multiport laparoscopic cholecystectomy is the standard surgical procedure for symptomatic gallbladder diseases. The latest evolution is single incision laparoscopic cholecystectomy (SILC). Single-site robotic cholecystectomy (SSRC) overcomes several limitations of manual SILC. The aim of this study is to present our initial experiences in SSRC and to compare its clinical outcomes with those of SILC. METHODS: This study retrospectively reviewed data for patients who received SSRC or SILC from February 2014 to September 2015. The following variables were analyzed: age, sex, body mass index, indications, pain scale, length of stay, and complications. The data were analyzed with Student t test or by Fisher exact test. RESULTS: The analysis included 51 SSRC (33 women, 18 men) and 63 SILC patients (40 women, 23 men). Patients in both groups had similar demographic features and indications for surgery. The SSRC group required no conversions to conventional laparoscopy and no additional trocars, whereas the SILC group had two (3.17%) cases. Length of stay did not significantly differ between the SSRC and SILC groups (4.29 ± 0.72 vs. 4.13 ± 0.93 days, respectively; p = 0.823). However, the SSRC group had shorter operative time (71.30 ± 48.88 vs. 74.70 ± 30.16 minutes; p = 0.772), less perioperative bile spillage (9.81% vs. 19.05%; p = 0.189), and less postoperative bile leakage (0% vs. 3.17%; p = 0.501). However, the parameters mentioned above were not statistically significant, whereas pain scale scores were significantly lower in the SSRC group (2.11 ± 0.76 vs. 3.98 ± 0.84; p < 0.01). CONCLUSIONS: Both SSRC and SILC are safe and feasible procedures for performing single incision cholecystectomy. SSRC, however, has the advantage of significantly decreased postoperative pain.

RESUMO

Hepatic cellular cancer (HCC) is one of the most common cancers in the world, which is a serious threat to human health and life quality. More than 700,000 people die of HCC each year on average, and its incidence increases in many countries. Chronic hepatitis B virus (HBV) infection has been identified as a dominant risk factor for HCC. The pathogenesis of HBV-induced hepatocarcinogenesis is, however, incompletely understood. Evidence currently available supports a key role of the HBV X protein (HBx) in the cancer transformation and malignant tumor metastasis. HBx is a multifunctional regulator that may cooperate with the host factors to exert its effects on transcription, signal transduction, cell cycle progression, apoptosis, protein degradation, expression of oncogene and anti-oncogene. This review presents the current knowledge in the molecular pathogenesis of HBx in the induction of HCC.

RESUMO

Few studies have compared percutaneous biliary stenting (PBS) and endoscopic biliary stenting (EBS) in terms of long-term effects on cholangiocarcinoma (CC), and few have systematically evaluated outcome associations in Taiwan. This study aimed to compare long-term outcomes between two treatments for unresectable CC: PBS and EBS. After propensity score matching (PSM) to reduce the effect of selection bias, 1002 CC patients were included in this analysis: 501 in the PBS group and 501 in the EBS group. The Kaplan-Meier method was used to construct the survival curve for all CC patients, and the Cox proportional hazards model was used for multivariate assessment of outcome predictors. After PSM, group comparisons revealed a significantly longer length of stay in the PBS group compared to the EBS group (25 days vs. 19 days, respectively; p < 0.001). Hospital costs were also significantly higher in the PBS group than in the EBS group (US$126,575 vs. US$89,326, respectively; p < 0.001). The median survival time was 3.7 months in all CC patients, 3.5 months in the PBS group, and 4.0 months in the EBS group. The 1-year, 3-year, and 5-year survival rates were 17.6%, 6.1%, and 3.2% in all CC patients; 16.6%, 4.8%, and 3.2% in the PBS group; and 18.6%, 7.27%, and 3% in the EBS group, respectively. The most important predictor of survival is extrahepatic CC. Medical professionals and healthcare providers should carefully consider the use of EBS for initial treatment of obstructive jaundice in patients with unresectable CC.

RESUMO

Estrogen-related receptor alpha (ERRα) plays an important role in the development of hormone-dependent cancers, but its roles in lung cancer remain elusive. The present study was aimed to investigate the effects of ERRα on the proliferation and metastasis of lung cancer A549 cells. The mRNA and protein levels of ERRα were detected in lung cancer A549 and MCF-7 cells and bronchial epithelial BEAS-2B cells by qRT-PCR and Western blotting, respectively. ERRα plasmid transfection and XCT-790 (an inverse agonist of ERRα) were used to up-regulate or down-regulate ERRα expression in A549 cells, respectively. The viability of A549 cells was measured by cell counting kit-8 (CCK-8) and the motility of A549 cells by wound healing assay and Transwell migration/invasion assay. The epithelial markers E-cadherin (E-Cad) and zona occludin-1 (ZO-1), the mesenchymal markers fibronectin (FN) and vimentin (Vim) and the transcription factors (Snail, Zeb1 Twist and Slug) were further detected at mRNA and protein levels by qRT-PCR and Western blotting, respectively. The results showed that ERRα promoted the growth of lung cancer A549 cells in vitro. XCT-790 significantly inhibited the migration and invasion of A549 cells. Over-expression of ERRα promoted the epithelial-to-mesenchymal transition (EMT) of A549 cells, down-regulated the epithelial makers E-Cad and ZO-1, and up-regulated the mesenchymal makers FN and Vim. Silencing of Slug, but not other transcription factors, significantly abolished the ERRα-induced EMT of A549 cells. It was suggested that ERRα promoted the migration and invasion of A549 cells by inducing EMT, and Slug was involved in the process. Targeting ERRα might be an efficient approach for lung cancer treatment.

RESUMO

OBJECTIVE: To explore the effect of Toll-like receptor 4 (TLR4) activation on the migration of asthmatic airway smooth muscle cell (ASMCs) induced by airway epithelial cells. METHODS: Primary ASMCs were cultured by the method of cell digestion. Cell culture supernatant of RTE cells were collected by TNF-alpha stimulation of epithelial cells. Detected the IL-8 and RANTES levels in the supernatant. The transmembrane migration of asthmatic ASMCs were detected by Modified Boyden chemotaxis chamber. The effect of TLR4 on the migration of asthmatic ASMCs induced by epithelial cells with TLR4 antibody drugs as a tool. RESULTS: The levels of IL-8 and RANTES in the supernatant of TNF-alpha groups were significantly increased, and that in the 20 ng/ml group was significantly higher than other groups (P < 0.01). The transmembrane migration of asthmatic ASMCs groups was increased than that of control group. The transmembrane migration of asthmatic ASMCs from asthma group and TNF-alpha + TLR4 antibody group was significantly decreased compared with that in TNF-alpha group (P < 0.01). The migration of asthma ASMCs from TNF-alpha + TLR4 antibody group was increased than that of asthma group (P < 0.05). CONCLUSION: TLR4 in the surface of asthmatic ASMCs may be activated by cytokines secreted by the airway epithelial cells and enhance the transmembrane migration of asthmatic ASMCs induced by airway epithelial cells so that it plays a role in airway remodeling of asthma.

RESUMO

OBJECTIVE: To study the changes of plasma vasoactive intestinal peptide (VIP) levels and the relationship of plasma VIP levels with feeding intolerance (FI) in preterm infants. METHODS: Plasma VIP concentrations were measured using radioimmunoassay in 53 preterm infants with FI 1, 4, 7 and 14 days after birth. Fifty-nine preterm infants without FI served as the control group. RESULTS: The fasting plasma concentrations of VIP in the FI group 1, 4 and 7 days after birth (129 ± 46, 144 ± 32 and 166 ± 31 pg/mL respectively) were significantly lower than those in the control group (195 ± 63, 197 ± 31 and 205 ± 34 pg/mL respectively) (P<0.05). The increased plasma VIP concentrations were associated with the increased gestational age, age in days and enteral feeding volume in the FI group. By 14 days, the plasma concentrations of VIP in the FI group (198 ± 41 pg/mL) were similar to those in the control group (202 ± 48 pg/mL) (P>0.05). The younger the infant's gestational age, the more prolonged the FI. Plasma levels of VIP on day 1 of life in the FI group were negatively correlated with the duration of FI (r=-0.799, P<0.05). CONCLUSIONS: Plasma levels of VIP might be related to the development of FI in preterm infants and might serve as a predictor of FI.

RESUMO

OBJECTIVE: To observe the curative effects of transmetil on Amanita verna poisoning. METHODS: Twelve cases with Amanita verna poisoning were reviewed. The patients were divided into 2 groups according to usage of transmetil: Group A was treated with traditional protocol (gastric lavage, catharsis, rehydration, diuresis, anti-infection and hemodialysis), Group B was treated with traditional protocol combined with transmetil. The liver function changes on the 1st, 3rd, 5th and 7th day after poisoning and the mortality were compared between 2 groups. RESULTS: Two cases in group A (6 patients) died. The mortality of group A was 33.3%. The AST levels continued to increase on the 3rd and 5th day, but decreased on the 7th day. TBIL continued to increased on the 1st, 3rd, 5th and 7th day. None in group B died. The TBIL level dropped at 7 d 5 patients showed an increase in ALT at 7 d and 3 patients showed a decrease in AST at 7 d. CONCLUSION: Transmetil may play an important role in reducing the mortality of Amanita verna poisoning.

RESUMO

OBJECTIVE: To explore the effect of triptolide on airway remodeling and the expression of nuclear factor-kappaB, Bcl-2 in asthmatic rats. METHODS: 40 rats were randomly divided into 5 groups (n = 8): (1) Control group; (2) Asthmatic 4 week group; (3) Asthmatic 6 week group; (4) Therapeutic 4 week group; (5) Therapeutic 6 week group. The airway resistance and eosinophilic inflammation of airway wall were observed. The airway wall thickness (WA/Pi), the bronchial smooth muscle thickness (smooth muscle area/Pi) and the number of bronchial smooth muscle nucleus (N/Pi) were measured by image analysis system. The expression of PCNA, nuclear factor-kappaB and Bcl-2 protein were determined by immunohistochemical staining and Western blot. The expression of Bcl-2 mRNA was determined by reverse transcription-polymerase chain reaction(RT-PCR). RESULTS: (1) The expression of NF-kappaB protein in asthmatic 4 week group and asthmatic 6 week group was significantly higher than that in control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 week group were significantly lower than those of asthmatic 4 week group, asthmatic 6 week group and therapeutic 4 week group, respectively (P < 0.01, P < 0.01 P < 0.05). (2) The expression of Bcl-2 protein and mRNA of asthmatic 4 week group and asthmatic 6 week group were significantly higher than those in control group respectively (P < 0.01). The expression of Bcl-2 protein of therapeutic 6 week group was significantly lower than those of asthmatic 4 week group, asthmatic 6 week group and therapeutic 4 week group respectively (P < 0.05, P < 0.01, P < 0.01), but the expression of Bcl-2 mRNA was significantly higher than the above-mentioned groups respectively (P < 0.01), the expression of Bcl-2 protein and mRNA of therapeutic 6 week group were higher than control group respectively (P < 0.05, P < 0.01). (3) The expression of PCNA protein of asthmatic 4 week group and asthmatic 6 week group were significantly higher than those of control group respectively (P < 0.01). (4) The WA/ Pi, the smooth muscle area/Pi and the N/Pi of asthmatic 4 week group and asthmatic 6 week group were significantly higher than those of control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 week group were significantly lower than those of asthmatic 4 week group, asthmatic 6 week group and therapeutic 4 week group, respectively (P < 0.01). (5) The airway resistance of asthmatic 4 week group and asthmatic 6 week group were significantly higher than those of the control group, respectively (P < 0.01). The above-mentioned parameters of therapeutic 6 week group were significantly lower than those of asthmatic 4 week group, asthmatic 6 week group and therapeutic 4 week group, respectively (P < 0.01, P < 0.01, P < 0.05). CONCLUSION: The proliferation of airway smooth muscle(ASM) is related with apoptosis of airway smooth muscle cells in asthma. NF-kappaB may be involved in the process. Triptolide may prevent apoptosis of ASMCs and decrease the proliferation of ASM by inhibiting the expression of NF-kappaB, Bcl-2.
