RESUMO

Objective: Assessing the risk of postoperative recurrence of chronic subdural hematoma (CSDH) is a clinical focus. To screen the main factors associated with the perioperative hematoma recurrence. The brain re-expansion is the core factor of recurrence. A clinical prognostic scoring system was also proposed. Methods: We included 295 patients with unilateral CSDH as the training group for modeling. Factors predicting postoperative recurrence requiring reoperation (RrR) were determined using univariate and multivariate regression analyses, and bivariate Pearson correlation coefficient analysis was used to exclude related factors. Receiver operating characteristic curve analysis evaluates the ability of main factors to predict RrR and determines the cut-off value of brain re-expansion rate. We developed a prognostic scoring system and conducted preliminary verification. A verification group including 119 patients with unilateral CSDH was used to verify the grading systems. Results: The key factors for predicting unilateral CSDH recurrence were cerebral re-expansion rate (≤ 40%) at postoperative days 7-9 (OR 25.91, p < 0.001) and the preoperative CT density classification (isodense or hyperdense, or separated or laminar types) (OR 8.19, p = 0.007). Cerebral atrophy played a key role in brain re-expansion (OR 2.36, p = 0.002). The CSDH prognostic grading system ranged from 0 to 3. An increased score was associated with a more accurate progressive increase in the RrR rate (AUC = 0.856). Conclusions: Our prognostic grading system could screen clinically high-risk RrR patients with unilateral CSDH. However, increased attention should be paid to brain re-expansion rate after surgery in patients with CSDH.

RESUMO

AIM: To explore the effect of parthenolide (PTL) on human uveal melanoma (UM) cells (C918 and SP6.5 cells) and its molecular mechanism. METHODS: Carboxyfluorescein succinimidyl amino ester (CFSE) assays and cell counting kit-8 (CCK-8) were performed to detect the cell viability. Flow cytometry was used to analyze cell cycle and apoptosis. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot assays were performed to measure proliferation-related and apoptosis-related factors. RESULTS: Firstly, PTL decreased the viability of C918 and SP6.5 cells in a dose-dependent manner, and the effect of PTL on C918 cells was stronger than on SP6.5; however, it did not affect normal cells. Secondly, PTL increased the proportion of cell number at cell cycle G1 phase in C918 cells, and decreased the proportion of cell number at S phase, but the proportion did not change at G2 phase. In addition, PTL induced the apoptosis of C918 cells, and decreased the expressions of Cyclin D1, B-cell lymphoma-2 (Bcl-2) and B-cell lymphoma-extra large (Bcl-XL). Also, PTL increased Cyclin inhibition protein 1 (P21), Bcl-2-associated X protein (Bax), Cysteinyl aspartate specific proteinas-3 (Caspase-3) and Caspase-9 expression. However, the expression of Caspase-8 was not changed. CONCLUSION: PTL inhibites proliferation and induces apoptosis in UM cells by arresting G1 phase and regulating mitochondrial pathway, however, it does not affect normal cells.

RESUMO

Aim: Ovarian cancer (OC) is the leading lethal gynecological cancer in women worldwide. Understanding the molecular mechanism of OC is very important for the identification of highly sensitive biomarkers for its prognosis. Methodology: We detected prognostic-related mRNA of OC in OncoLnc database. The main features between the unfavorable and favorable prognostic OC mRNAs were analyzed and Kyoto Encyclopedia of Genes and Genomes pathway enrichment as well as correlation analysis was conducted in our study. Conclusion: Our findings suggest that neural activities can promote OC progression, indicating poor prognosis, among which axon guidance functions most significantly govern the main neural activities, followed by neurogenesis and angiogenesis. Four neural genes (NTN1, UNC5B, EFNB2 and EFNA5) could serve as promising biomarkers and therapeutic targets for precision medicine to treat OC patients.

RESUMO

Lithocholic acid (LCA) is known to kill glioma cells while sparing normal neuronal cells. However, the anti-glioma mechanism of LCA is unclear at present. Although malondialdehyde (MDA) is not specific to detect tumors, biologically active α,ß-unsaturated aldehydes can be used to detect the outcome of gliomas, especially the mitochondria, as a research tool. The purpose of this research was to determine the optimum conditions for a lipid peroxidation model, according to changes in the aldehydes formed from the reaction between 2-thiobarbituric acid and biologically active α,ß-unsaturated aldehydes. Experimental methods and procedures were successfully established for a model of lipid peroxidation induced by H2O2 in glioma mitochondria for glioma treatment and optimum conditions for LCA treatment were determined. The optimal conditions for the model were a glioma mitochondrial concentration of 1.5 mg/ml, H2O2 concentration of 0.3 mg/ml, duration of action of 30 min, and addition of 4.0 ml of 46 mM thiobarbituric acid. The effect of LCA, as determined by changes in the UV peaks at 450, 495, and 532 nm, was optimal at a concentration of 100 µM, a duration of action of 15 min, and in an acidic microenvironment. The study concluded that a suitable concentration of LCA has anti-glioma effects as determined by the effect on changes in the UV peaks at 450, 495 and 532 nm and the mitochondrial model developed should be conducive to further in-depth research.

RESUMO

Chronic subdural hematoma (CSDH) is a common neurosurgical condition. Currently, surgery is the most effective medical intervention for treatment of this disorder. Because CSDH is an inflammatory angiogenic disease involving multifactorial mechanisms, a better understanding of CSDH pathogenesis should facilitate clinical management. Therefore, the purpose of this review is to describe recent progress in elucidation of molecular mechanisms causing CSDH and to summarize the body of knowledge gained from past drug treatment studies. Because hematoma fluid and outer membrane characteristics may be linked to pathology, they could serve as disease biomarkers. Moreover, past drug treatment studies have shown that such biomarkers may mutually synergize to initiate and promote CSDH progression. These findings suggest that modulation of biomarker expression or function using drug therapy may benefit CSDH patients.

RESUMO

BACKGROUND: To investigate clinical characteristics of postcranioplasty seizures (PCS) first observed after cranioplasty after decompressive craniectomy (DC) to treat traumatic brain injury and to define factors that increase PCS risk. METHODS: This retrospective study, covering the period between January 2008 and July 2015, compared PCS in postcranioplasty patients. Postcranioplasty seizures risk factors included diabetes mellitus, hypertension, time between DC and cranioplasty, duraplasty material, cranioplasty contusion location, electrocautery method, PCS type, and infection. Multivariate logistic regression analysis was performed and confidence intervals (CIs) were calculated (95% CI). RESULTS: Of 270 patients, 32 exhibited initial PCS onset postcranioplasty with 11.9% incidence (32/270). Patients fell into immediate (within 24 hours), early (from 1 to 7 days), and late (after 7 days) PCS groups with frequencies of 12, 5, and 15 patients, respectively. Generalized, partial, and mixed seizure types were observed in 13, 13, and 6 patients, respectively. Multivariate logistic regression analysis showed increased risk with increasing age (>50 years). Cranioplasty contusion location, precranioplasty deficits, duraplasty material, and monopolar electrocautery were predictive of PCS onset (P < 0.05). Increased DC to cranioplasty interval increased risk but was not statistically significant (P = 0.062). CONCLUSIONS: Understanding risk factors for PCS will benefit the management of cranioplasty patients.

RESUMO

OBJECTIVES: Meningiomas are the most common type of primary intracranial tumor. Atypical meningiomas are especially difficult to manage due to frequent disease recurrence. This study aimed to examine the role of stathmin (coded by the gene STMN1) as a factor in atypical meningioma recurrence. PATIENTS AND METHODS: A total of 59 sporadic atypical meningioma formalin-fixed paraffin-embedded (FFPE) samples were collected. The mRNA levels of the biomarker gene STMN1 were tested using quantitative RT-PCR. RESULTS: We observed significant up-regulation of STMN1 mRNA expression in recurrent tumors in comparison with primary tumors (p<0.05). Moreover, mRNA expression levels of STMN1 significantly correlated with Ki-67 score (r=0.93, p<0.01). Multivariate survival analyses indicated that high expression of STMN1, high Ki-67 score, and more advanced patient age at diagnosis (>60yrs) each act as independence prognostic factors for recurrence. Kaplan-Meier analysis revealed that STMN1 expression pattern could effectively predict prognosis of atypical meningioma in patients (p<0.01). CONCLUSIONS: Our study indicates for the first time that an increased risk of sporadic atypical meningioma recurrence can be found in cases with elevated expression of STMN1. These results suggest that STMN1 expression might serve as a biomarker for determining patient atypical meningioma prognosis.

RESUMO

There is a small part of the pathological type of the meningioma has a malignant tendency and patients have the poor prognosis. Looking for effective biomarkers to predict the degree of malignancy of the tumors, will help us to better manage the patient and guide the treatment. The present study aims at investigating the prognostic value of the expression of Stathmin in a series of meningiomas of different grade. We integrated eight published microarray datasets of meningiomas to screen grade biomarkers in meningiomas patients using the WebArrayDB platform. We focused on Stathmin, Using formalin-fixed paraffin-embedded (FFPE) tumor samples, we corroborated the relationship between Stathmin and patient outcomes using qRT-PCR for gene expression. We also found expression of Stathmin that atypical/anaplastic meningiomas have higher expression than benign meningiomas (p<0.01). No correlation between Stathmin expression and age, gender and tumor extent of resection was found (p>0.05). Moreover, increased Stathmin expression was correlated to higher meningioma grade and shorter disease-free survival (DFS) of meningioma patients with Simpson I resection. Stathmin might be promising targets to improve the cure rates in meningiomas.

RESUMO

BACKGROUND: Chronic subdural hematoma (CSDH) is an inflammatory angiogenic disease. It is believed that vascular endothelial growth factor (VEGF) plays an important role in pathological CSDH angiogenesis. METHODS: In this study, magnetic resonance imaging (MRI) results were used to assign 115 primary CSDH patients to four MRI types. The four MRI types are described as follows: type 1 (T1-weighted low, T2-weighted low), type 2 (T1-weighted high, T2-weighted low), type 3 (T1-weighted mixed, T2-weighted mixed), and type 4 (T1-weighted low/high, T2-weighted high). The four MRI types were then correlated with CSDH stage and patient hematoma fluid and serum VEGH concentrations that were measured using an enzyme-linked immunosorbent assay (ELISA). Neurological status was assessed by Markwalder scoring at admission and six-month follow-up. RESULTS: The mean VEGF concentration was significantly higher in CDSH hematoma fluid samples than in patient sera (p<0.01). In unilateral CSDH hematoma fluid samples, VEGF concentration was highest in type 1 (21,613.5±1473.3pg/ml), next highest in type 2 (18,071.8±1737.1pg/ml), lower in type 3, and lowest in type 4 patients (13,153.7±3854.4pg/ml, 7265.7±726.2pg/ml, respectively). High VEGF concentrations strongly correlated with MRI type (unilateral CSDH group r=0.838, bilateral CSDH group r=0.851, p<0.01). Moreover, higher hematoma fluid VEGF concentrations correlated with markedly higher recurrence in type 1 (3/19, 15.8%) vs. type 4 unilateral CSDH patients (1/27, 3.7%). CONCLUSIONS: The present study reports a significant correlation between CSDH hematoma fluid VEGF concentration and MRI results. Therefore, MRI results could be used to predict hematoma fluid VEGF concentrations in CSDH patients.

RESUMO

BACKGROUND: Data on the experience of endoscopic retrograde cholangiopancreatography (ERCP) in the management of pancreaticobiliary maljunction (PBM) is limited. METHODS: A retrospective review of patients with PBM who underwent therapeutic ERCP at our endoscopy center between January 2008 and January 2016 was performed. Demographic, clinical, radiological and endoscopic data was documented. Patients who underwent sphincterotomy were divided into dilated group and undilated group based on their common channel diameter. RESULTS: Sixty-three PBM patients underwent 74 ERCP procedures. The technical success rate was 97.3%. ERCP therapy significantly decreased the levels of elevated liver enzymes and bilirubin. After an average of 27 months follow-up, 7 patients (11.1%) were lost. The overall effective rate of ERCP therapy was 60.7% (34/56). Decline in severity and frequency of abdominal pain was significant. Procedure-related complications were observed in 5 (6.8%) cases. Between the dilated group and undilated group, no significant difference was observed in effective rate, adverse events and follow-up results. CONCLUSIONS: ERCP can serve as a transitional step to stabilize PBM patients before definitive surgery. PBM patients with undilated common channel could benefit from sphincterotomy as well as those with dilated common channel.

RESUMO

BACKGROUND: Glioblastoma multiforme (GBM) is the most common malignant and lethal type of primary central nervous system tumor in humans. In spite of its high lethality, a small percentage of patients have a relatively good prognosis, with median survival times of 36 months or longer. The identification of clinical subsets of GBM associated with distinct molecular genetic profiles has made it possible to design therapies tailored to treat individual patients. METHODS: We compared microarray data sets from long-term survivors (LTSs) and short-term survivors (STSs) to screen for prognostic biomarkers in GBM patients using the WebArrayDB platform. We focused on FBLN4, IGFBP-2, and CHI3L1, all members of a group of 10 of the most promising, differentially regulated gene candidates. Using formalin-fixed paraffin-embedded GBM samples, we corroborated the relationship between these genes and patient outcomes using methylation-specific polymerase chain reaction (PCR) for MGMT methylation status and quantitative reverse transcription PCR for expression of these genes. RESULTS: Expression levels of the mRNAs of these 3 genes were higher in the GBM samples than in normal brain samples and these 3 genes were significantly upregulated in STSs compared to the levels in LTS samples (P<0.01). Furthermore, Kaplan-Meier analysis showed that the expression patterns of FBLN4 and IGFBP-2 serve as independent prognostic indicators for overall survival (P<0.01 and P<0.05, respectively). CONCLUSION: To our knowledge, this is the first report describing FBLN4 as a prognostic factor for GBM patient survival, demonstrating that increased GBM survival time correlates with decreased FBLN4 expression. Understanding FBLN4 expression patterns could aid in the creation of powerful tools to predict clinical prognoses of GBM patients.

RESUMO

BACKGROUND/AIMS: To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of symptomatic pancreas divisum (PD) and to discuss whether ERCP procedures and outcomes in younger patients differ from those of adults. METHODS: Symptomatic patients with PD were included in the study and divided into underaged (age ≤17 years) and adult (age ≥18 years) group. The clinical information of each patient was reviewed, and then the patients were contacted by telephone or their medical records were reviewed to determine their long-term followup outcomes. RESULTS: A total of 141 procedures were performed in 82 patients (17 underaged and 65 adult patients). The ERCP indications included abdominal pain (39.02%), pancreatitis (12.20%), recurrent pancreatitis (36.59%), and other discomfort (12.20%). The endoscopic interventions included endoscopic pancreatic sphincterotomy in 44.68% of the patients, bouginage in 26.95%, pancreatic ductal stone extraction in 19.15%, endoscopic nasopancreatic drainage in 21.99%, and endoscopic retrograde pancreatic drainage in 56.74%. After a median follow-up of 41 months, the overall response rate was 62.32%. Between the underaged group and the adult group, significant differences were not observed in the ERCP procedures, complications and longterm follow-up results. CONCLUSIONS: ERCP is a safe and effective treatment for symptomatic PD. Based on the details, complications, and follow-up results, the ERCP procedure did not present differences between the underaged and adult groups.

RESUMO

Chronic subdural hematoma (CSDH) is an inflammatory and angiogenic disease. Vascular endothelial growth factor (VEGF) has an important effect on the pathological progression of CSDH. The matrix metalloproteinases (MMPs) and VEGF also play a significant role in pathological angiogenesis. Our research was to investigate the level of MMPs and VEGF in serum and hematoma fluid. Magnetic Resonance Imaging (MRI) shows the characteristics of different stages of CSDH. We also analyzed the relationship between the level of VEGF in subdural hematoma fluid and the appearances of the patients' MRI. We performed a study comparing serum and hematoma fluid in 37 consecutive patients with primary CSDHs using enzyme-linked immunosorbent assay (ELISA). MMP-2 and MMP-9 activity was assayed by the gelatin zymography method. The patients were divided into five groups according to the appearance of the hematomas on MRI: group 1 (T1-weighted low, T2-weighted low, n=4), group 2 (T1-weighted high, T2-weighted low, n=11), group 3 (T1-weighted mixed, T2-weighted mixed, n=9), group 4 (T1-weighted high, T2-weighted high, n=5), and group 5 (T1-weighted low, T2-weighted high, n=8). Neurological status was assessed by Markwalder score on admission and at follow-up. The mean age, sex, and Markwalder score were not significantly different among groups. The mean concentration of VEGF, MMP-2, and MMP-9 were significantly higher in hematoma fluid than in serum (p<0.01). The level of pro-MMP-2 was higher in hematoma fluid (p<0.01). Measurement of MMP-9 showed both pro and active forms in both groups, but levels were higher in hematoma fluid (p<0.01 and p<0.01, respectively). Mean VEGF concentration was highest in group 1 (21,979.3±1387.3 pg/mL), followed by group 2 (20,060.1±1677.2 pg/mL), group 3 (13,746.5±3529.7 pg/mL), group 4 (7523.2±764.9 pg/mL), and lowest in group 5 (6801.9±618.7 pg/mL). There was a significant correlation between VEGF concentrations and MRI type (r=0.854). The present investigation is the first report showing that the concentrations of MMP-2 and MMP-9 are significantly elevated in hematoma fluid, suggesting that the MMPs/VEGF system may be involved in the angiogenesis of CSDH. We also demonstrate a significant correlation between the concentrations of VEGF and MRI appearance. This finding supports the hypothesis that high VEGF concentration in the hematoma fluid is of major pathophysiological importance in the generation and steady increase of the hematoma volume, as well as the determination of MRI appearance.

RESUMO

BACKGROUND: Photodynamic therapy with the placement of a biliary stent may improve the prognosis in patients with unresectable cholangiocarcinoma. The aim of this research is to determine the hazard ratio of photodynamic therapy with stent compared to biliary stenting alone or other therapies for the treatment of cholangiocarcinoma. METHODS: Several databases were searched from inception to December 31 2013 for trials comparing photodynamic therapy+stent vs. stent-only or other treatments for cholangiocarcinoma. The outcomes of interest included patient survival, the changes of serum bilirubin levels, the quality of life (Karnofsky performance status), and adverse events. The hazard ratios (HR) were extracted from the survival curves using Tierney's Method. LnHR and its variance were pooled using an inverse variance-weighted average. Inconsistency was quantified using I(2) statistics. RESULTS: In all, 8 trials comparing PDT+stent with other therapeutic methods were selected. We made a meta-analysis based on the 7 trials, which compared the result of PDT+stent and the stent-only group. HR summarizes the survival for the two groups. Overall survival was significantly better in patients who received photodynamic therapy than those who did not [HR=0.49, 95% confidence interval (CI), 0.33∼0.73, P=0.0005]. Among the 8 trials (642 subjects), 5 assessed the changes of serum bilirubin levels, and/or Karnofsky performance status, as other indications for improvement. In all, the incidence for phototoxic reaction is 11.11%. The incidence for other events in photodynamic therapy and the stent-only group was 13.64% and 12.79%, respectively. CONCLUSION: The palliative treatment of cholangiocarcinoma, with photodynamic therapy, is associated with an increased survival benefit, an improved biliary drainage, and a better quality of life. However, the quality of this evidence is low.

RESUMO

A benign fibrous histiocytoma with primary site of origin in the parietal bone has not yet been reported in the literature. We report here a case concerning a 12-year-old girl with a 14-month history of an enlarging parietal bone mass. The tumor was excised after removal of the cortical bone and resection of the tumor surrounding the cortical bone erosion using pre-plasticity titanium repair. Both postoperative histopathological examination and immunohistochemical analysis were consistent with a benign fibrous histiocytoma. No clinical or computed tomography (CT) radiological signs of tumor recurrence and/or metastasis were observed at 12 months. Although a primary benign fibrous histiocytoma of the parietal bone is a rare tumor, it should be considered as a potential diagnosis for any cranial tumor. Surgical intervention is the most effective treatment technique for a benign fibrous histiocytoma.

RESUMO

OBJECTIVE: Patients with chronic subdural haematoma and contralateral subdural effusion are rare after head injury. Surgery might reduce clinical progression of subdural effusion, but is not used routinely. This study aimed to investigate the effect of surgery on subdural effusion and clinical outcome. METHODS: A retrospective study was performed, comparing operation and non-operation in the patients with chronic subdural haematoma and contralateral subdural effusion, in a series of 47 patients divided into two groups. The operation group of 21 patients underwent bilateral surgery. The non-operation group of 26 patients underwent surgery on the side with chronic subdural haematoma. Neurological status was assessed by the Glasgow Coma score and Modified Rankin Scale score on admission and at follow-up. All cases underwent pre- and post-operative computed tomography scans. RESULTS: Pre-operative clinical and radiological data were similar in the two groups. The rate of subdural effusion progression was significantly lower in the operation group than in the non-operation group (p < 0.05). Thirteen cases (50%) in the non-operation group and three cases (14.3%) in the operation group had progression of subdural effusion to chronic subdural haematoma (p < 0.05). Chronic subdural haematoma recurrence rate, mortality and neurological recovery were similar, with no significant difference between groups. CONCLUSIONS: The patients benefitted from surgery for subdural effusion when they had chronic subdural haematoma and contralateral subdural effusion.

RESUMO

BACKGROUND: Carcinoid tumors are slow growing neuroendocrine tumors which can originate from various sites within the body. A carcinoid tumor originating in the medulla spinalis has not previously been reported in the literature. CASE REPORT: We report a case of a 33-year-old man, presenting with a five-month history of bilateral lower extremity pain, as well as paresthesia, and mild weakness in one lateral lower extremity. A lumbar laminectomy of L3 to L5 and en bloc resection of the tumor was performed. Postoperative histopathology and immunohistochemical analysis of the tumor were consistent with that of a carcinoid tumor. There were no clinical or radiological signs of tumor recurrence or metastasis at the patient's two year postoperative follow-up. CONCLUSIONS: During the differential diagnosis of medulla spinalis tumors, the possibility of a primary carcinoid tumor originating within the medulla spinalis should be considered. An accurate tumor classification is imperative to ensure that the most effective course of treatment is pursued.

RESUMO

BACKGROUND: Gliomas are the most common type of all central nervous system tumors. Almost all patients diagnosed with these tumors have a poor prognostic outcome. We aimed to identify novel glioma prognosis-associated candidate genes. METHODS: We applied WebArrayDB software to span platform integrate and analyze the microarray datasets. We focused on a subset of the significantly up-regulated genes, the minichromosome maintenance (MCM) family. We used frozen glioma samples to predict the relationship between the expression of MCMs and patients outcome by qPCR and western blot. RESULTS: We found that MCMs expression was significantly up-regulated in glioma samples. MCM2-7 and MCM10 expressions were associated with WHO tumor grade. High MCM2 mRNA expression appeared to be strongly associated with poor overall survival in patients with high grade glioma. Furthermore, we report that MCM7 is strongly correlated with patient outcome in patients with WHO grade II-IV tumor. MCM3 expression was found to be up-regulated in glioma and correlated with overall survival in patients with WHO grade III tumor. MCM2, MCM3 and MCM7 expression levels were of greater prognostic relevance than histological diagnosis according to the current WHO classification system. CONCLUSIONS: High expression of MCM 2, MCM3 and MCM7 mRNA correlated with poor outcome and may be clinically useful molecular prognostic markers in glioma.

RESUMO

OBJECTIVE: To analyze the microsurgical treatment regimens of cavernous sinus hemangioma. METHODS: The microsurgical experiences were reviewed and analyzed for 17 cases of operatively and pathologically confirmed cavernous sinus cavernous hemangioma at our hospital from January 2008 to January 2012. There were 6 males and 11 females with an average age of 48.5 years. RESULTS: Among them, there were total (n = 14) and subtotal (n = 3) resection. And there was no occurrence of postoperative mortality. According to the results of imaging follow-up, total resection cases had no recurrence while subtotal residual tumor was progression-free after radiotherapy. Oculomotor, abducens and trigeminal nerves retained varying degrees of neurological function at 3-6 months postoperation. CONCLUSION: Based on the size of tumor and growth direction, appropriate surgical approaches may be selected. And a combination of skilled microsurgical techniques and proper resection may reduce bleeding and facilitate total tumor removal so as to reduce the degree of neurological deficits and improve the long-term postoperative quality-of-life.
