Patient demographics, clinical features, imaging data, treatment details, and follow-up results were analyzed.Results: Sixty-one consecutive patients were included in this study;48(79%) were men and 13(21%) women,with a mean age of 49.4 ± 13.4 years(range 24–73 years). There were 42 patients(69%) who underwent open surgery, 18(29%) undergoing endovascular embolization or stent implantation, and one(2%) undergoing ultrasound-guided thrombin injection. All patients successfully underwent open or interventional treatment. The median follow-up was 46.8 months(2.5–117.9 months), and the overall reintervention rate was 10%. Of these,one(5%) patient in the interventional treatment group and five(12%) patients in the open surgery group underwent reintervention. The overall complication rate was 8%, with complications occurring only in the open surgery group. No deaths occurred in the peri-operative period. No late complications, such as thrombosis or pseudoaneurysm recurrence, were observed.Conclusion: Peripheral artery pseudoaneurysms arising from iatrogenic or traumatic causes can be effectively treated by both open surgery and interventional procedures in selected patients with acceptable mid-and long-term outcomes.展开更多

Human M2 macrophages were induced in vitro and co-cultured in non-contact with gastric carcinoma SGC-7901 cells. Changes in the secretory Sema4 D level in the SGC-7901 cell supernatant were measured using an enzymelinked immunosorbent assay. The effects of TAMs on SGC-7901 cell invasion and migration were assessed with invasion and migration assays, respectively.RESULTS CD68 and Sema4 D protein expression was significantly higher in gastric carcinoma tissues than in adjacent normal tissues(71.7% vs 33.8% and 74.5% vs 42.8%, respectively; P < 0.01). CD68 and Sema4 D protein expression was significantly associated with histological differentiation, TNM stage, and lymph node metastasis(P < 0.05), and their expression levels were positively correlated with one another(r = 0.467, P < 0.01). In the in vitro experiment, secretory Sema4 D protein expression was significantly increased in the supernatant of SGC-7901 cells co-cultured with TAMs compared with the blank control(1224.13 ± 29.43 vs 637.15 ± 33.84, P < 0.01). Cell invasion and metastasis were enhanced in the Transwell invasion and migration assays(P < 0.01).CONCLUSION TAMs promote the invasion and metastasis of gastric carcinoma cells possibly through upregulated secretory Sema4 D protein expression. Combined detection of TAM markers, CD68 and Sema4 D, in gastric carcinoma tissue shows potential to predict the trend of gastric carcinoma progression.展开更多

AIM To investigate the prognostic value of LVI in CRC and identify the associated genomic alterations. METHODS We performed a retrospective analysis of 1219 CRC patients and evaluated the prognostic value of LVI for overall survival by the Kaplan-Meier method and multivariate Cox regression analysis. We also performed an array-based comparative genomic hybridization analysis of 47 fresh CRC samples to examine the genomic alterations associated with LVI. A decision tree model was applied to identify special DNA copy number alterations (DCNAs) for differentiating between CRCs with and without LVI. Functional enrichment and protein-protein interaction network analyses were conducted to explore the potential molecular mechanisms of LVI. RESULTS LVI was detected in 150 (12.3%) of 1219 CRCs, and the presence was positively associated with higher histological grade and advanced tumor stage (both P < 0.001). Compared with the non-LVI group, the LVI group showed a 1.77-fold (95% confidence interval: 1.40-2.25, P < 0.001) increased risk of death and a significantly lower 5-year overall survival rate (P < 0.001). Based on the comparative genomic hybridization data, 184 DCNAs (105 gains and 79 losses) were identified to be significantly related to LVI (P < 0.05), and the majority were located at 22q, 17q, 10q, and 6q. We further constructed a decision tree classifier including seven special DCNAs, which could distinguish CRCs with LVI from those without it at an accuracy of 95.7%. Functional enrichment and proteinprotein interaction network analyses revealed that the genomic alterations related to LVI were correlated with inflammation, epithelial-mesenchymal transition, angiogenesis, and matrix remodeling. CONCLUSION LVI is an independent predictor for survival in CRC, and its development may correlate with inflammation, epithelial-mesenchymal transition, angiogenesis, and matrix remodeling.展开更多

This study aimed to examine the effect of high-fat diet on cholesterol metabolism in rats and the role of Na+/K+-ATPase/Src/ERK signaling pathway in the process. Forty male SD rats were evenly divided into high-fat diet group and control group at random. Animals in the former group were fed on high-fat diet for 12 weeks, and those fed on basic diet served as control. Blood lipids, including total cholesterol(TC), triglyceride(TG), high density lipoprotein-cholesterol(HDL-C), and low density lipoprotein-cholesteral(LDL-C) levels, were detected at 3, 6 and 12 weeks. The ratio of cholesterol content in cytoplasm to that in cell membrane was detected in liver tissues. RT-PCR and Western blotting were used to measure the expression of lipid metabolism-associated genes(HMG-Co A reductase and SREBP-2) after 12-week high-fat diet. Na+/K+-ATPase/Src/ERK signaling pathway-related components(Na+/K+-ATPase α1, Src-PY418 and pERK1/2) were also measured by Western blotting. The results showed that the serum TC, TG, and LDL-C levels were significantly higher in high-fat diet group than those in control group, while the HDL-C level was significantly lower in high-fat diet group at 6 weeks(P<0.01). High-fat diet led to an increase in the cholesterol content in the cytoplasm and cell membrane. The ratio of cholesterol content in cytoplasm to that in cell membrane was elevated over time. The expression of HMG-Co A reductase and SREBP-2 was significantly suppressed at m RNA and protein levels after 12-week high-fat diet(P<0.05). Moreover, high-fat diet promoted the expression of Na+/K+-ATPase α1 but suppressed the phosphorylation of Src-PY418 and ERK1/2 at 12 weeks(P<0.05). It was concluded that high-fat diet regulates cholesterol metabolism, and Na+/K+-ATPase signaling pathway is involved in the process possibly by regulating the expression of lipid metabolism-associated proteins HMG-Co A reductase and SREBP-2.展开更多

M...Irradiation from diverse sources is ubiquitous and closely associated with human activities. Radiation therapy (RT), an important component of multiple radiation origins, is a common therapeutic modality for cancer. More importantly, RT provides significant contribution to oncotherapy by killing tumor cells. However, during the course of therapy, irradiation of normal tissues can result in a wide range of side effects, including self-limited acute toxicities, mild chronic symptoms, or severe organ dysfunction. Although numerous promising radioprotective agents have emerged, only a few have successfully entered the market because of various limitations. At present, the widely accepted hypothesis for protection against radiation-caused injury involves the Wnt canonical pathway. Activating the Wnt/β-catenin signaling pathway may protect the salivary gland, oral mucosa, and gastrointestinal epithelium from radiation damage. The underlying mechanisms include inhibiting apoptosis and preserving normal tissue functions. However, aberrant Wnt signaling underlies a wide range of pathologies in humans, and its various components contribute to cancer. Moreover, studies have suggested that Wnt/ β-catenin signaling may lead to radioresistance of cancer stem cell.

文摘BACKGROUND Intra-abdominal infections(IAIs)is the most common type of surgical infection,with high associated morbidity and mortality rates.In recent years,due to the use of antibiotics,various drug-resistant bacteria have emerged,making the treatment of abdominal infections more challenging.Early surgical exploration can reduce the mortality of patients with abdominal infection and the occurrence of complications.However,available evidence regarding the optimal timing of IAI surgery is still weak.In study,we compared the effects of operation time on patients with abdominal cavity infection and tried to confirm the best timing of surgery.AIM To assess the efficacy of early vs delayed surgical exploration in the treatment of IAI,in terms of overall mortality.METHODS A systematic literature search was performed using PubMed,EMBASE,Cochrane Central Register of Controlled Trials,Ovid,and ScienceDirect.The systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses method.Based on the timing of the surgical operation,we divided the literature into two groups:Early surgery and delayed surgery.For the early and delayed surgery groups,the intervention was performed with and after 12 h of the initial surgical intervention,respectively.The main outcome measure was the mortality rate.The literature search was performed from May 5 to 20,2021.We also searched the World Health Organization International Clinical Trials Registry Platform search portal and ClinicalTrials.gov on May 20,2021,for ongoing trials.This study was registered with the International Prospective Register of Systematic Reviews.RESULTS We identified nine eligible trial comparisons.Early surgical exploration of patients with IAIs(performed within 12 h)has significantly reduced the mortality and complications of patients,improved the survival rate,and shortened the hospital stay.CONCLUSION Early surgical exploration within 12 h may be more effective for the treatment of IAIs relative to a delayed operation.
文摘Purpose: This study aimed to report our 10-year experience with the management of iatrogenic(penetrating trauma) and traumatic(blunt or penetrating trauma) peripheral artery pseudoaneurysms, based on data from a tertiary referral center.Methods: From January 2012 to December 2021, the medical records of consecutive patients with iatrogenic and traumatic peripheral artery pseudoaneurysms were retrospectively reviewed. Patient demographics, clinical features, imaging data, treatment details, and follow-up results were analyzed.Results: Sixty-one consecutive patients were included in this study;48(79%) were men and 13(21%) women,with a mean age of 49.4 ± 13.4 years(range 24–73 years). There were 42 patients(69%) who underwent open surgery, 18(29%) undergoing endovascular embolization or stent implantation, and one(2%) undergoing ultrasound-guided thrombin injection. All patients successfully underwent open or interventional treatment. The median follow-up was 46.8 months(2.5–117.9 months), and the overall reintervention rate was 10%. Of these,one(5%) patient in the interventional treatment group and five(12%) patients in the open surgery group underwent reintervention. The overall complication rate was 8%, with complications occurring only in the open surgery group. No deaths occurred in the peri-operative period. No late complications, such as thrombosis or pseudoaneurysm recurrence, were observed.Conclusion: Peripheral artery pseudoaneurysms arising from iatrogenic or traumatic causes can be effectively treated by both open surgery and interventional procedures in selected patients with acceptable mid-and long-term outcomes.

文摘Background: This study aims to better understand diagnosing and treating arterial gastrointestinal fistulas. Methods: The diagnosis and treatment of two patients with arterial gastrointestinal fistulas were reported, and the experience with diagnosis and treatment was summarized. Results: In these two cases, both patients were admitted with bleeding as the primary complaint, both underwent emergency laparotomies, and both patients were diagnosed with small intestinal bleeding before surgery. the first patient died as a result of an abdominal aortic aneurysm rupture caused by chronic vascular repair and postoperative implant infection;the second patient underwent vascular repair on time, we treated him with third-generation cephalosporin, and after he was stabilized, we performed left total iliac stent placement and left internal iliac artery embolization;he had no fever after surgery, his incision was healed, and he was successfully discharged from the hospital. Conclusion: Aortic gastrointestinal fistula is rare and has a high mortality rate, attention should be paid to distinguishing it from small intestinal bleeding. Timely diagnosis and rapid surgical treatment are keys to improving survival.
文摘AIM:To discuss strategies and prognosis for the emergency treatment of ruptured bleeding in primary hepatocellular carcinoma.METHODS:The retrospective analysis was performed by examining the emergency treatment experiences of60 cases of ruptured bleeding in primary hepatocellular carcinoma.The treatment methods included surgical tumour resection,transcatheter arterial embolization(TAE)and non-surgical treatment.Univariate and multivariate analyses were performed to identify the risk factors that impacted 30-d mortality in the research groups.RESULTS:The 30-d mortality of all patients was 28.3%(n=17).The univariate analysis showed that ChildPugh C level liver function,shock,massive blood transfusion and large tumour volume were risk factors thatinfluenced 30-d mortality.The multivariate analysis showed that shock and massive blood transfusion were independent risk factors that impacted the 30-d mortality of surgical resection.As for the TAE patients,larger tumour volume was a risk factor towards prognosis.CONCLUSION:Radical resection and TAE therapy would achieve better results in carefully selected ruptured hepatocellular tumours.
文摘BACKGROUND The incidence of hypertriglyceridemic acute pancreatitis(HTG-AP)has increased yearly,but updated population-based estimates on the incidence of HTG-AP are lacking.Reducing serum triglyceride(TG)levels quickly is crucial in the early treatment of HTG-AP.Decreased serum TG levels are treated by non-invasive methods,which include anti-lipidemic agents,heparin,low-molecular weight heparin,and insulin,and invasive methods,such as blood purification including hemoperfusion(HP),plasmapheresis,and continuous renal replacement therapy.However,authoritative guidelines have not been established.Early selection of appropriate treatment is important and beneficial in controlling the development of HTG-AP.AIM To evaluate the effect between patients treated with intravenous insulin(INS)and HP to guide clinical treatment.METHODS We retrospectively reviewed 371 patients with HTG-AP enrolled in the Department of Fujian Provincial Hospital form April 2012 to March 2021.The inpatient medical and radiologic records were reviewed to determine clinical features,severity,complications,mortality,recurrence rate,and treatment.Multivariate logistic regression analyses were used to analyze risk factors for severe HTG-AP.Propensity score matching was used to compare the clinical outcomes of INS and HP.RESULTS A total of 371 patients met the HTG-AP criteria.The incidence of HTG-AP was increased by approximately 2.6 times during the 10 years(8.4%in April 2012-March 2013 and 22.3%in April 2020-March 2021).The highest incidence rate of acute pancreatitis was observed for men in the age group of 30-39 years.The amylase level was elevated in 80.1%of patients but was only three times the normal value in 46.9%of patients.The frequency of severe acute pancreatitis(26.9%),organ failure(31.5%),rate of recurrence(32.9%),and mortality(3.0%)of HTG-AP was high.Improved Marshall score,modified computed tomography severity index score,baseline TG,baseline amylase,C-reactive protein(CRP),albumin,aspartate aminotransferase,low-density lipoprotein cholesterol,urea nitrogen,creatinine,calcium,hemoglobin,free triiodothyronine,admission to intensive care unit,and mortality were significantly different between patients with different grades of severity(P<0.050).Multivariate logistic regression analysis confirmed that high CRP[P=0.005,odds ratio(OR)=1.011,95%CI:1.003-1.019],low calcium(P=0.003,OR=0.016,95%CI:0.001-0.239),and low albumin(P=0.023,OR=0.821,95%CI:0.693-0.973)were risk factors of severe HTG-AP.After propensity score matching adjusted by sex,age,severity of HTG-AP,and baseline TG,the serum TG significantly decreased in patients treated with INS(P<0.000)and HP(P<0.000)within 48 h.However,the clearance rate of TG(57.24±33.70%vs 56.38±33.61%,P=0.927)and length of stay(13.04±7.92 d vs 12.35±6.40 d,P=0.730)did not differ between the two groups.CONCLUSION The incidence of HTG-AP exhibited a significant increase,remarkable severity,and recurrent trend.Patients with mild and moderately severe acute pancreatitis can be treated effectively with INS safely and effectively without HP.
文摘AIM To study the role of semaphorin 4 D(Sema4 D) expression promoted by tumor-associated macrophages(TAMs) in gastric carcinoma cells and its clinical significance in the invasion and metastasis of gastric carcinoma.METHODS CD68 and Sema4 D expression was analyzed in gastric carcinoma and adjacent normal tissues from 290 patients using the immunohistochemical streptavidinperoxidase method, and their relationships with clinicopathological features were evaluated. Human M2 macrophages were induced in vitro and co-cultured in non-contact with gastric carcinoma SGC-7901 cells. Changes in the secretory Sema4 D level in the SGC-7901 cell supernatant were measured using an enzymelinked immunosorbent assay. The effects of TAMs on SGC-7901 cell invasion and migration were assessed with invasion and migration assays, respectively.RESULTS CD68 and Sema4 D protein expression was significantly higher in gastric carcinoma tissues than in adjacent normal tissues(71.7% vs 33.8% and 74.5% vs 42.8%, respectively; P < 0.01). CD68 and Sema4 D protein expression was significantly associated with histological differentiation, TNM stage, and lymph node metastasis(P < 0.05), and their expression levels were positively correlated with one another(r = 0.467, P < 0.01). In the in vitro experiment, secretory Sema4 D protein expression was significantly increased in the supernatant of SGC-7901 cells co-cultured with TAMs compared with the blank control(1224.13 ± 29.43 vs 637.15 ± 33.84, P < 0.01). Cell invasion and metastasis were enhanced in the Transwell invasion and migration assays(P < 0.01).CONCLUSION TAMs promote the invasion and metastasis of gastric carcinoma cells possibly through upregulated secretory Sema4 D protein expression. Combined detection of TAM markers, CD68 and Sema4 D, in gastric carcinoma tissue shows potential to predict the trend of gastric carcinoma progression.

文摘BACKGROUND Lymphovascular invasion (LVI) is suggested to be an early and important step in tumor progression toward metastasis, but its prognostic value and genetic mechanisms in colorectal cancer (CRC) have not been well investigated. AIM To investigate the prognostic value of LVI in CRC and identify the associated genomic alterations. METHODS We performed a retrospective analysis of 1219 CRC patients and evaluated the prognostic value of LVI for overall survival by the Kaplan-Meier method and multivariate Cox regression analysis. We also performed an array-based comparative genomic hybridization analysis of 47 fresh CRC samples to examine the genomic alterations associated with LVI. A decision tree model was applied to identify special DNA copy number alterations (DCNAs) for differentiating between CRCs with and without LVI. Functional enrichment and protein-protein interaction network analyses were conducted to explore the potential molecular mechanisms of LVI. RESULTS LVI was detected in 150 (12.3%) of 1219 CRCs, and the presence was positively associated with higher histological grade and advanced tumor stage (both P < 0.001). Compared with the non-LVI group, the LVI group showed a 1.77-fold (95% confidence interval: 1.40-2.25, P < 0.001) increased risk of death and a significantly lower 5-year overall survival rate (P < 0.001). Based on the comparative genomic hybridization data, 184 DCNAs (105 gains and 79 losses) were identified to be significantly related to LVI (P < 0.05), and the majority were located at 22q, 17q, 10q, and 6q. We further constructed a decision tree classifier including seven special DCNAs, which could distinguish CRCs with LVI from those without it at an accuracy of 95.7%. Functional enrichment and proteinprotein interaction network analyses revealed that the genomic alterations related to LVI were correlated with inflammation, epithelial-mesenchymal transition, angiogenesis, and matrix remodeling. CONCLUSION LVI is an independent predictor for survival in CRC, and its development may correlate with inflammation, epithelial-mesenchymal transition, angiogenesis, and matrix remodeling.

文摘Abnormal cholesterol metabolism is associated with an elevated risk of developing atherosclerosis, hypertension, and diabetes etc. Na+/K+-ATPase was found to regulate cholesterol synthesis, distribution and trafficking. This study aimed to examine the effect of high-fat diet on cholesterol metabolism in rats and the role of Na+/K+-ATPase/Src/ERK signaling pathway in the process. Forty male SD rats were evenly divided into high-fat diet group and control group at random. Animals in the former group were fed on high-fat diet for 12 weeks, and those fed on basic diet served as control. Blood lipids, including total cholesterol(TC), triglyceride(TG), high density lipoprotein-cholesterol(HDL-C), and low density lipoprotein-cholesteral(LDL-C) levels, were detected at 3, 6 and 12 weeks. The ratio of cholesterol content in cytoplasm to that in cell membrane was detected in liver tissues. RT-PCR and Western blotting were used to measure the expression of lipid metabolism-associated genes(HMG-Co A reductase and SREBP-2) after 12-week high-fat diet. Na+/K+-ATPase/Src/ERK signaling pathway-related components(Na+/K+-ATPase α1, Src-PY418 and pERK1/2) were also measured by Western blotting. The results showed that the serum TC, TG, and LDL-C levels were significantly higher in high-fat diet group than those in control group, while the HDL-C level was significantly lower in high-fat diet group at 6 weeks(P<0.01). High-fat diet led to an increase in the cholesterol content in the cytoplasm and cell membrane. The ratio of cholesterol content in cytoplasm to that in cell membrane was elevated over time. The expression of HMG-Co A reductase and SREBP-2 was significantly suppressed at m RNA and protein levels after 12-week high-fat diet(P<0.05). Moreover, high-fat diet promoted the expression of Na+/K+-ATPase α1 but suppressed the phosphorylation of Src-PY418 and ERK1/2 at 12 weeks(P<0.05). It was concluded that high-fat diet regulates cholesterol metabolism, and Na+/K+-ATPase signaling pathway is involved in the process possibly by regulating the expression of lipid metabolism-associated proteins HMG-Co A reductase and SREBP-2.
文摘Irradiation from diverse sources is ubiquitous and closely associated with human activities. Radiation therapy (RT), an important component of multiple radiation origins, is a common therapeutic modality for cancer. More importantly, RT provides significant contribution to oncotherapy by killing tumor cells. However, during the course of therapy, irradiation of normal tissues can result in a wide range of side effects, including self-limited acute toxicities, mild chronic symptoms, or severe organ dysfunction. Although numerous promising radioprotective agents have emerged, only a few have successfully entered the market because of various limitations. At present, the widely accepted hypothesis for protection against radiation-caused injury involves the Wnt canonical pathway. Activating the Wnt/β-catenin signaling pathway may protect the salivary gland, oral mucosa, and gastrointestinal epithelium from radiation damage. The underlying mechanisms include inhibiting apoptosis and preserving normal tissue functions. However, aberrant Wnt signaling underlies a wide range of pathologies in humans, and its various components contribute to cancer. Moreover, studies have suggested that Wnt/ β-catenin signaling may lead to radioresistance of cancer stem cell. These facts markedly complicate any definition of the exact function of the Wnt pathway.
