RESUMEN

Recently, a distinctive group of S100 protein/CD34-positive spindle cell mesenchymal neoplasms characterized by a predominant lipofibromatosis-like neural pattern harboring recurrent gene rearrangements involving NTRK1-3, RAF1, RET, ROS1, ALK, and MET has been identified. BRAF rearrangements have been rarely documented in this group of neoplasms. Herein, we report a 54-year-old man with a 1.3-cm painless mass located in the subcutis of left back. The tumor was composed of mildly atypical, short-spindle shaped to ovoid cells with fascicles and whorls intervening between and admixed with the subcutaneous adipose tissues and nerve bundles. Focally abundant thick, band-like stromal hyalinization was also noted. The neoplastic cells showed diffuse reactivity for S100 protein and CD34 and multifocal immunopositivity for markers associated with perineurial differentiation including epithelial membrane antigen, GLUT1, and claudin-1. Fluorescence in situ hybridization analyses showed positive for BRAF rearrangement and negative for rearrangements involving NTRK1, RET, and ROS1. The tumor was narrowly excised and recurred after 24 months of follow-up. To our knowledge, we report the second case of BRAF-rearranged spindle cell mesenchymal tumor with predominant lipofibromatosis-like neural tumor pattern. Expression of markers associated with perineurial differentiation is exceptional and represents a potential diagnostic pitfall, which may cause significant diagnostic confusion with a peripheral nerve sheath tumor.

RESUMEN

Ossifying fibromyxoid tumor (OFMT) is a rare mesenchymal neoplasm of uncertain line of differentiation that can be subdivided into typical, atypical, and malignant tumors. Cytogenetically, OFMT is characterized by recurrent gene rearrangement involving PHF1 in up to 85% of cases. The most common PHF1 fusion partner is EP400, present in approximately half of cases. Most recently, a novel fusion of PHF1-TFE3 was identified in about 10% of PHF1-rearranged OFMTs. Herein, we report a unique case of PHF1-TFE3 fusion atypical OFMT with prominent collagenous rosettes. A 50-year-old male patient presented with a slowly growing, painless mass in the right foot for 4 years. Gross examination showed a 3.5-cm, subcutaneous well-circumscribed, lobulated mass. Microscopic examination revealed a well-demarcated but un-encapsulated tumor without a peripheral bony shell. The neoplasm was composed of mildly atypical spindle to ovoid cells with increased mitosis (2 mitoses per 10 high-power fields) arranged in a multinodular manner within a fibromyxoid stroma, which contained numerous small, irregular collagenous rosettes surrounded by radiating growth of tumor cells. The neoplastic cells were diffusely positive for TFE3 and CD10. RNA sequencing revealed an in-frame fusion between PHF1 exon 12 and TFE3 exon 7. Subsequent Fluorescence in-situ hybridization analyses demonstrated positive for rearrangements of both the PHF1 and TFE3 loci. The patient was free of disease at 63 months' follow-up. Our case exhibits atypical features and prominent collagenous rosettes, expanding the morphological spectrum of OFMT with PHF1-TFE3 fusion.

RESUMEN

BACKGROUND: Fatigue is an important clinical finding in patients with chronic hepatitis virus infection. However, studies assessing fatigue in patients with chronic hepatitis B (CHB) are very limited. This study aimed to quantify the severity of fatigue in patients with CHB, to determine whether perceived fatigue reflects impairment of functional ability, and to explore potential causes. METHODS: A total of 133 patients with histologically proven CHB and 59 community controls were assessed using the fatigue impact scale (FIS). RESULTS: The degree of fatigue was significantly higher in patients with CHB than in controls (mean (range) FIS 24.9 (0-91) vs. 15.7 (0-31), p < 0.001). Fatigue experienced by patients with CHB was similar to that in primary biliary cirrhosis (PBC) (n = 20) (FIS 22.2 vs. 20.9, p = 0.28). No association was found between FIS and biochemistry and histological parameters of liver disease severity. Significant associations were found between fatigue severity and cognitive impairment (r = 0.39, p < 0.001), daytime somnolence (r = 0.32, p < 0.001), scores of the Chronic Liver Disease Questionnaire (r = - 0.31, p < 0.001), and autonomic symptoms (r = 0.43, p < 0.001). The level of autonomic symptom was the only factor independently associated with the degree of fatigue. CONCLUSION: Fatigue is a significant problem of functional ability impairment in CHB and similar in degree to that in PBC patients. Fatigue in patients with CHB appears to be unrelated to the severity of liver disease but is associated with significant autonomic symptoms.

RESUMEN

Prostate cancer (PC) is a very important kind of male malignancies. When PC evolves into a stage of hormone resistance or metastasis, the fatality rate is very high. Currently, discoveries and advances in miRNAs as biomarkers have opened the potential for the diagnosis of PC, especially early diagnosis. miRNAs not only can noninvasively or minimally invasively identify PC, but also can provide the data for optimization and personalization of therapy. Moreover, miRNAs have been shown to play an important role to predict prognosis of PC. The purpose of this meta-analysis is to integrate the currently published expression profile data of miRNAs in PC, and evaluate the value of miRNAs as biomarkers for PC. All of relevant records were selected via electronic databases: Pubmed, Embase, Cochrane, and CNKI based on the assessment of title, abstract, and full text. we extracted mean ± SD or fold change of miRNAs expression levels in PC versus BPH or normal controls. Pooled hazard ratios (HRs) with 95% confidence intervals (CI) for overall survival (OS) and recurrence-free survival (RFS), were also calculated to detect the relationship between high miRNAs expression and PC prognosis. Selected 104 articles were published in 2007-2017. According to the inclusion criteria, 104 records were included for this meta-analysis. The pooled or stratified analyze showed 10 up-regulated miRNAs (miR-18a, miR-34a, miR-106b, miR-141, miR-182, miR-183, miR-200a/b, miR-301a, and miR-375) and 14 down-regulated miRNAs (miR-1, miR-23b/27b, miR-30c, miR-99b, miR-139-5p, miR-152, miR-187, miR-204, miR-205, miR-224, miR-452, miR-505, and let-7c) had relatively good diagnostic and predictive potential to discriminate PC from BPH/normal controls. Furthermore, high expression of miR-32 and low expression of let-7c could be used to differentiate metastatic PC from local/primary PC. Additional interesting findings were that the expression profiles of five miRNAs (miR-21, miR-30c, miR-129, miR-145, and let-7c) could predict poor RFS of PC, while the evaluation of miR-375 was associated with worse OS. miRNAs are important regulators in PC progression. Our results indicate that miRNAs are suitable for predicting the different stages of PC. The detection of miRNAs is an effective way to control patient's prognosis and evaluate therapeutic efficacy. However, large-scale detections based on common clinical guidelines are still necessary to further validate our conclusions, due to the bias induced by molecular heterogeneity and differences in study design and detection methods.

RESUMEN

BACKGROUND AND AIM: Quantitative digital imaging analysis to evaluate liver fibrosis is accurate, but its clinical use is limited by its high cost and lack of standardization. We aimed to validate an inexpensive digital imaging analysis technique for fibrosis quantification in chronic hepatitis B patients. MATERIAL AND METHODS: In total, 142 chronic hepatitis B patients who underwent liver biopsy and analysis of serum fibrosis markers were included. Images of Sirius red stain sections were captured and processed using Adobe Photoshop CS3 software. The percentage of fibrosis (fibrosis index) was determined by the ratio of the fibrosis area to the total sample area, expressed in pixels, and calculated automatically. RESULTS: A strong correlation between the fibrosis index and the Ishak, Metavir, and Laennec histological staging systems were observed (r = 0.83, 0.86, and 0.84, respectively; < 0.001). The cutoff value associated with cirrhosis was 7.7% with an area under the receiver operating characteristic curve (AUROC) of 0.95 (95% confidence interval [CI], 0.92-0.99, p < 0.001). Furthermore, the fibrosis index yielded a cutoff value of 8.9% (AUROC, 0.74; 95% CI, 0.66-0.86), 12% (AUROC, 0.84; 95% CI, 0.75-0.93), and 14% (AUROC, 0.97; 95% CI, 0.92-1.0) for the diagnosis of cirrhosis 4a, 4b, and 4c, respectively. No serum markers or fibrosis models were correlated with the fibrosis index in Metavir F2-F4. CONCLUSIONS: The present digital imaging analysis technique is reproducible and available worldwide, allowing its use in clinical practice, and can be considered as a complementary tool to traditional histological methods.

RESUMEN

BACKGROUND/AIM: We aimed to evaluate the histopathologic characteristics of HBeAg-negative chronic hepatitis B patients with low hepatitis B virus (HBV) DNA levels (<2000 IU/mL) and persistently normal ALT levels and to determine indicators of significant liver disease. METHODS: We examined 102 consecutive subjects who underwent percutaneous liver biopsy. Significant predictors of liver disease (stage ≥2 fibrosis or stage 1 fibrosis plus grade ≥2 inflammation), including demographic, clinical, and laboratory variables, were evaluated by means of univariate and multivariate logistic regression analyses. RESULTS: Among the patients, 75.5% (77/102) had grade 0-1 inflammation and 77.5% (79/102) had stage 0-1 fibrosis. However, 38.2% (39/102) had significant liver disease. There were no statistically significant differences in clinical parameters such as age, biochemical profile, HBV DNA levels, HBsAg levels, and platelet count between patients with significant and those with nonsignificant liver disease. Patients with significant liver disease had higher values of aspartate transferase-to-platelet ratio index (APRI) and FIB-4 index compared with those with nonsignificant liver disease (0.35±0.21 vs. 0.27±0.12, P=0.02; 1.58±0.97 vs. 1.13±0.54, P=0.009, respectively). The area under the receiver operating characteristic (AUROC) curve of APRI for identifying active liver histology was 0.64 (95% CI, 0.53-0.75; P=0.019); the cutoff value was 0.24 with a sensitivity of 74% and specificity of 55%. In comparison, FIB-4 had equal power (the AUROC was 0.66) in predicting active liver histology. CONCLUSION: Among patients presenting with low HBV DNA levels and normal ALT levels, about 38.2% had significant liver disease. Neither serum HBsAg nor HBV DNA levels correlate with liver histology. However, APRI≥0.24 might be considered an indicator of liver biopsy.

RESUMEN

BACKGROUND: MiR-125b functions as an oncogene in many cancers; however, its clinical significance and molecular mechanism in gastric cancers have never been sufficiently investigated. Here, we elucidated the functions and molecular regulated pathways of MiR-125b in gastric cancer. METHODS: We investigated MiR-125b expression in fresh tissues from 50 gastric cancer patients and 6 gastric cancer cell lines using RT-PCR, and explored its prognostic value by hybridizing MiR-125b in situ for 300 clinical gastric tumor tissues with pathological diagnosis and clinical parameters. The effects of MiR-125b on gastric cancer cells and downstream target genes and proteins were analyzed by MTT, transwell assay, RT-PCR, and western blot on the basis of silencing MiR-125b in vitro. Luciferase reporter plasmid was constructed to demonstrate MiR-125b's direct target. RESULTS: MiR-125b was upregulated in gastric cancer tissues and cell lines, and significantly promoted cellular proliferation, migration, and invasion by downregulating the expression of PPP1CA and upregulating Rb phosphorylation. MiR-125b expression was significantly correlated with tumor size and depth of invasion, lymph nodes, distant metastasis, and TNM stage. The high-MiR-125b-expression group had a significantly poorer prognosis than the low-expression group (P < 0.05) in stages I, II, and III, and the 5-year survival rate in of the high-expression group was significantly lower than that of the low-expression group. CONCLUSIONS: MiR-125b functions as an oncogene by targeting downregulated PPP1CA and upregulated Rb phosphorylation in gastric cancer. MiR-125b not only promotes cellular proliferation, migration, and invasion in vitro, but also acts as an independent prognostic factor in gastric cancer.

RESUMEN

Aim: To identify optimally therapeutic exercise interventions for improving motor ability among patients with Parkinson's disease (PD), we conducted a network meta-analysis (NMA) of randomized controlled trials comparing different exercise regimens. Methods: Relevant RCTs were retrieved by searching PubMed, Embase, Cochrane, Web of Science, CINAHL, CBM, China National Knowledge Infrastructure (CNKI), Wan fang, VIP, and other databases from inception to July 9, 2023 is available in English as the primary language. Exercise outcomes as measured by Movement Disorder Society- Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS-III) score change were evaluated and ranked using STATA software version 18.0. All included studies were assessed for methodological quality using the Cochrane Risk of Bias tool. Results: The final NMA included 71 studies involving 3,732 participants, 87 intervention experiments, and 27distinct interventions. Although most exercise interventions showed some efficacy (reducing MDS-UPDRS-III score), cumulative ranking probability surface (SUCRA) values indicated that the best exercise interventions for motor function improvement were archery (95.6%), riding a bicycle (80.9%), and binary rhythm dance (80.8%). Conclusion: An exercise intervention comprising archery, cycling, and(or) binary rhythm dance may yield superior improvements in motor function among patients with Parkinson's disease.

RESUMEN

PURPOSE: Hobnail features may enhance the clinical aggressiveness of papillary thyroid carcinoma (PTC). However, whether a low proportion (<30%) of these features contributes to increased PTC aggressiveness remains unclear. This study investigated whether PTC cases with a low proportion hobnail features (<30%) exhibit clinical invasiveness and pathological features of aggressiveness. METHODS: Pathological specimens from patients with postoperatively diagnosed PTC were retrospectively analyzed. Among them, 29 PTC cases with a low proportion of hobnail features (<30%) were compared with 173 consecutive classical PTC (cPTC) cases. Data regarding age at presentation, sex, tumor size, number of tumors, and histological characteristics were obtained by reviewing electronic medical records. Postoperative information was obtained during follow-up visits and telephone interviews. RESULTS: Twenty-nine patients with PTC with a low proportion of hobnail features (<30%) were identified, exhibiting a median age of 34 years. At a median follow-up of 31 (IQR, 23-37) months, two patients had recurrent disease in the PTC with a low proportion of hobnail features (<30%) group, whereas there was no recurrence in the cPTC group. No distant metastasis and postoperative mortality were observed in either group. Compared with the cPTC group, patients with PTC and a low proportion of hobnail features exhibited larger tumor volumes and higher susceptibility to capsular invasion and lymph node metastasis. Tumor size and hobnail features emerged as independent risk factors for lymph node metastasis. CONCLUSION: PTC with a low proportion hobnail features (<30%) and larger tumor volumes are associated with the occurrence of lymph node metastasis. A low proportion of hobnail features (<30%) in PTC may heighten invasiveness, elevating the risk of recurrence.

RESUMEN

The uneven spatial and temporal distribution of light resources and water scarcity during the grain-filling stage pose significant challenges for sustainable crop production, particularly in the arid areas of the Loess Plateau in Northwest China. This study aims to investigate the combined effects of drought and shading stress on winter wheat growth and its physio-biochemical and antioxidative responses. Wheat plants were subjected to different drought levels- full irrigation (I100), 75% of full irrigation (I75), 50% of full irrigation (I50), and 25% of full irrigation (I25), and shading treatments - 12, 9, 6, 3 and 0 days (SD12, SD9, SD6, SD3, and CK, respectively) during the grain-filling stage. The effects of drought and shading treatments reduced yield in descending order, with the most significant reductions observed in the SD12 and I25 treatments. These treatments decreased grain yield, spikes per plant, 1000-grain weight, and spikelets per spike by 160.67%, 248.13%, 28.22%, and 179.55%, respectively, compared to the CK. Furthermore, MDA content and antioxidant enzyme activities exhibited an ascending trend with reduced irrigation and longer shading durations. The highest values were recorded in the I75 and SD12 treatments, which increased MDA, SOD, POD, and CAT activities by 65.22, 66.79, 65.07 and 58.38%, respectively, compared to the CK. The Pn, E, Gs, and iCO2 exhibited a decreasing trend (318.14, 521.09, 908.77, and 90.85%) with increasing shading duration and decreasing irrigation amount. Drought and shading treatments damage leaf chlorophyll fluorescence, decreasing yield and related physiological and biochemical attributes.

RESUMEN

BACKGROUND: Liver fibrosis is a predisposing factor for liver cancer. This study will investigate the predictive role of the Triglyceride-glucose and Gamma-glutamyl transferase index (TyG-GGT) as a non-invasive indicator of advanced liver fibrosis in individuals with obesity or overweight. METHOD: We enrolled patients who underwent metabolic and bariatric surgery as well as intraoperative liver biopsies at Zhejiang provincial people's hospital from August 2020 to March 2023. Clinical characteristics, comorbidities, laboratory data, and pathological variables of patients were collected and analysed. Then, we conducted logistics regression model to compare the performance of the TyG-GGT index with other 4 non-invasive models. RESULTS: A total of 65 patients were included in this study. 43(66.2%) of them were female, with the mean body mass index (BMI) of 39.0 ± 7.3 kg/m2. Meanwhile, 24(36.9%) patients were diagnosed with diabetes. Advanced liver fibrosis were observed in 16.9% of patients, while liver cirrhosis was found in 4.6% of patients. The multivariable logistics regression showed that TyG-GGT was an independent risk factor of advanced liver fibrosis (OR = 6.989, P = 0.049). Additionally, compared to another 4 non-invasive liver fibrosis models (NFS = 0.66, FIB4 = 0.65, METS-IR = 0.68, APRI = 0.65), TyG-GGT exhibits the highest AUC value of 0.75. CONCLUSIONS: More than one-third of patients undergoing metabolic and bariatric surgery are afflicted with nonalcoholic steatohepatitis (NASH), and a significant proportion exhibit advanced fibrosis. TyG-GGT was a potentially reliable predictor for screening individuals with overweight or obesity at high risk of advanced liver fibrosis, thus providing clinical guidance for early intervention in this targeted group.

RESUMEN

OBJECTIVE: To retrospectively analyze the clinical efficacy of olecranon osteotomy approach in the treatment of Dubberley type Ⅲ coronal fractures of the distal humerus and summarize the treatment experience. METHODS: From January 2016 to June 2020, 17 patients (5 males and 12 females) with Dubberley type Ⅲ coronal fractures of the distal humerus were treated by olecranon osteotomy approach. The age ranged from 37 to78 years old with an average of (58.5±12.9) years old. According to Dubberley classification, there were 5 cases of type Ⅲ A and 12 cases of type Ⅲ B. The curative effect was evaluated using the Borberg-Morrey elbow function score. The flexion, extension and rotation range of motion of the elbow joint, complications and postoperative imaging evaluation were recorded. RESULTS: All the 17 patients got bony union. The follow-up time ranged from 12 to 33 months with an average of (15.6±5.6) months. There was 1 case of ischemic necrosis of capitulum humeri, 2 cases of traumatic arthritis and 1 case of heterotopic ossification, 1 case of malunion of fracture. The range of motion was (114.80±19.50) °. The Broberg-Morrey score was 85.3±8.2, excellent in 5 cases, good in 9 cases, fair in 3 cases and poor in 0 case. CONCLUSION: Through olecranon osteotomy approach, the articular surface of distal humerus could be fully exposed, and the operation is convenient. Anatomical reduction and rigid fixation of the articular surface of distal humerus are the key factors for the succesful outcome.

RESUMEN

Aim: To explore the correlations between the expression of zinc finger protein 521 (ZNF521) with immune invasion and prognosis of gastric cancer. Methods: Expression of ZNF521 was examined by immunohistochemistry in gastric cancer cases. Kaplan-Meier plotter was used to determine the relationships between ZNF521 and prognosis. TIMER and GEPIA were used to analyze the correlation between ZNF521 expression and gene markers of immune cell infiltration. Results: The expression of ZNF521 was up-regulated in gastric cancer samples. Kaplan-Meier analysis indicated that higher expression of ZNF521 was associated with poor prognosis. The expression of ZNF521 was correlated with infiltrating levels of CD4+ T and CD8+ T cells, macrophages, neutrophils, and dendritic cells in gastric cancer, which also correlated with diverse immune marker sets. Conclusions: ZNF521 is correlated significantly with immune cell infiltration and is a valuable biomarker for prognosis in gastric cancer.

RESUMEN

BACKGROUND: Citron kinase (CIT) is a protein related to cytokinesis and is an important abscission regulator. However, the relationship between CIT and hepatocellular carcinoma (HCC) is unclear. The aim of this study was to investigate the expression CIT in HCC tissues, and explore the connection between this expression and clinicopathological characteristics of HCC. METHODS: Immunohistochemistry staining on 235 HCC tissues and 96 non-tumorous liver tissues controls was performed to examine the CIT protein expression. We then analyzed the correlation between protein expression and clinicopathological parameters via χ2 tests, and we performed overall survival analyses via the Kaplan-Meier survival approach. Based on the online Oncomine Expression Array and UALCAN databases, we more broadly compared CIT mRNA expression between normal and HCC tissues. Finally, we compared CIT mRNA expression in these databases to protein expression in our study and explored potential sources for any observe differences. RESULTS: Compared to normal tissues, CIT expression was significantly lower in HCC tissues. Low CIT expression was found to be related to gender, tumor size, Edmondson Grade, Microvascular invasion, serum AFP levels and poor overall survival. Based on the online databases, CIT mRNA expression was found to be high in HCC tissues and decreased in normal tissues. We hypothesize that this unexpected result is due to a negative feedback loop whereby low protein CIT levels mediate increased CIT mRNA levels. CONCLUSIONS: Lower CIT protein levels are associated with a poorer prognosis in HCC patients, and lower CIT protein levels may mediate a negative feedback loop leading to increased CIT mRNA levels.

RESUMEN

In the title coordination compound, [Cd(C14H8N2O4)(H2O)]n, the Cd(II) cation and the coordinated water molecule lie on a twofold axis, whereas the ligand lies on an inversion center. The Cd(II) center is five-coordinated in a distorted square-pyramidal geometry by four carboxylate O atoms from four different 4,4'-diazenediyldibenzoate (ddb) anions and one water O atom. The three-dimensional frameworks thus formed by the bridging ddb anions interpenetrate to generate a three-dimensional PtS-type network. Additionally, the coordination water molecule and the carboxylate O atom form a hydrogen-bonding interaction, stabilizing the three-dimensional framework structure.

BACKGROUND: The safety of nucleos(t)ide analogue (NA) treatment cessation remains one of the most controversial topics in the management of chronic hepatitis B (CHB) patients. This study investigated the efficiency of 48-week pegylated-interferon (peg-IFN) alfa-2a consolidation therapy on viral relapse after discontinued NA treatment in CHB patients who achieved hepatitis B e antigen (HBeAg) seroconversion for > 1 year. METHODS: NA-treated HBeAg-positive patients who achieved the standard of discontinued NA treatment (i.e. time of HBeAg seroconversion > 1 year) were randomly assigned to receive peg-IFN consolidation (n = 24) treatment or continue original NA therapy (n = 24) for 48 weeks. The treatments were then discontinued, and the patients were observed up to 144 weeks. The primary endpoint was the proportion of patients with viral relapse at week 144 among those who received at least one dose of study drug or had at least one study visit [modified intention-to-treat population (mITT)]. RESULTS: Of the 24 patients who received peg-IFN treatment, 6 (25%) experienced viral relapse and 8 (36.3%) showed HBsAg loss during 96 weeks of treatment-free follow-up. Of the patients who underwent NA consolidation treatment, only 1 (4.3%) of 23 patients showed HBsAg loss and 14 (58.3%) of 24 patients experienced viral relapse during follow-up. HBsAg level decline < 0.25 log10 IU/mL at week 96 was significantly associated with viral relapse. CONCLUSION: A 48-week peg-IFN alfa-2a consolidation therapy increased the rate of HBsAg loss and sustained viral replication suppression in HBeAg-positive patients who achieved HBeAg seroconversion for > 1 year after NA treatment discontinuation.

RESUMEN

OBJECTIVE: To investigate the mRNA expression of basic fibroblast growth factor (bFGF) and hepatocyte growth factor (HGF) in gastric carcinoma and correlation thereof with intratumoral microvascular density (IMD), proliferating cell nuclear antigen labeling index (PCNA LI), tumor invasion and metastasis, and patients' survival. METHODS: In situ hybridization and immunohistochemistry were used to test the expression of bFGF and HGF mRNA and protein expression of CD34 and PCNA in 118 specimens of gastric carcinoma. RESULTS: The positive rates of bFGF mRNA and HGF mRNA were 57.6% and 52.5% respectively; the positive expression rates of bFGF mRNA and HGF mRNA of the cases at the stage T3-T4, and those with vessel invasion, lymph node metastasis, and distant metastasis were all significantly higher than the positive expression rates of the cases at the stage T1-T2, and those without lymph node metastasis, vessel invasion, and distant metastasis (all P < 0.05). The mean IMD levels of the patients positive in bFGF and HGF mRNA expression were (46.63 +/- 13.96) and (46.73 +/- 13.34) pieces/0.72 mm2, both significantly higher than those of the patients negative in bFGF and HGF mRNA expression [(34.56 +/- 15.16) and (35.98 +/- 14.92) pieces/0.72 mm2) respectively, t = 4.62, P = 0.000, and t = 4.01, P = 0.000]. The PCNA LI of the of the patients positive in bFGF and HGF mRNA expression was (66.53 +/- 13.61) and (67.56 +/- 13.41) respectively, both significantly higher5 than those of patients negative in bFGF and HGF mRNA expression [(54.79 +/- 10.57) and (55.04 +/- 11.01) respectively, t = 5.83, P = 0.000, and t = 4.91, P = 0.000]. The 5-year survival rates of the patients negative in bFGF and HGF mRNA expression were 60.00% and 67.90% respectively, both significantly higher than those of the patients positive in bFGF and HGF mRNA expression (30.90% and 21.00% respectively, both P = 0.000). IMD, PCNA LI, and bFGF mRNA were all positively related to HGF mRNA (all P = 0.000). CONCLUSIONS: bFGF and HGF promote angiogenesis and proliferation of gastric cancer, and in involved in tumor invasion and metastasis. They can be used as markers of prognosis of gastric cancer in clinical practice.

RESUMEN

Corticotropin releasing hormone binding protein (CRHBP) mediates the reaction between corticotropin releasing hormone (CRH) and corticotropin releasing hormone receptors (CRHRs). It is expressed in a number of organs, and the expression of CRHBP is associated with tumorigenesis and cancer progression. The aim of the present study was to investigate CRHBP expression levels in hepatocellular carcinoma (HCC) and its association with patient clinicopathological characteristics as well as prognosis. The expression of CRHBP was examined by immunohistochemistry in 169 HCC tissues and 151 adjacent non-tumorous tissues. The results were validated by western blotting using patient tissues and liver cancer cell lines. The association of CRHBP expression with clinicopathological patient characteristics and survival rate was analyzed statistically. Expression of CRHBP was detected in 142/151 (94.0%) non-tumorous liver tissues, and 84/169 (49.7%) HCC tissues (P<0.001). The expression of CRHBP was negatively associated with tumor size (P=0.013), Edmondson Grade (P=0.002), hepatitis B virus antigen (P=0.020), and α-fetoprotein levels (P=0.014). Patients exhibiting low CRHBP expression were associated with shorter survival time compared with those exhibiting high CRHBP expression (P=0.012). The results of western blotting analysis suggest that reduced CRHBP expression is frequently observable in patients with HCC. Low CRHBP expression in HCC tissues may be a predictor of clinical prognosis and a potential therapeutic target for HCC.
