Although the efficacy of transcatheter arterial chemoembolization (TACE) has been recommended as first-line therapy for nonsurgical patients with hepatocellular carcinoma (HCC), it is difficult to accurately predict the efficacy of TACE. Therefore, this study evaluated the efficacy of TACE for HCC using magnetic resonance (MR) diffusion-weighted imaging (DWI). A total of 84 HCC patients who received initial TACE were selected and assigned to the stable group (n=39) and the progressive group (n=45). Before TACE treatment, a contrast-enhanced MR scan and DWI (b=300, 600, and 800 s/mm2) were performed on all patients. The modified response evaluation criteria in solid tumors were used for evaluation of tumor response. Receiver operating characteristic curve was employed to predict the value of apparent diffusion coefficient (ADC) for TACE efficacy. The ADC values of HCC patients in the progressive group were higher than those in the stable group at different b-values (b=300, 600, and 800 s/mm2) before TACE treatment. The area under the curve of ADC values with b-values of 300, 600, and 800 s/mm2 were 0.693, 0.724, and 0.746; the threshold values were 1.94×10−3 mm2/s, 1.28×10−3 mm2/s, and 1.20×10−3 mm2/s; the sensitivity values were 55.6%, 77.8%, and 73.3%; and the specificity values were 82.1%, 61.5%, and 71.8%, respectively. Our findings indicate that the ADC values of MR-DWI may accurately predict the efficacy of TACE in the treatment of HCC patients. © 2017 Wu et al.

Background: Transforming growth factor beta1 (TGFβ1) is a multifunctional cytokine involved in inflammation and pathogenesis of atherosclerosis. The aim of the present study was to investigate the relationship between human TGFβ1 gene +869T>C (rs1800470), -509C>T (rs1800469) single nucleotide polymorphisms (SNPs) and haplotypes and cerebral infarction (CI) in a Chinese population. Methods: The genetic association study was performed in 450 Chinese patients (306 male and 144 female) with CI and 450 control subjects (326 male and 124 female). TGFβ1 gene +869T>C and -509C>T polymorphisms were identified with amplification refractory mutation system polymerase chain reaction and DNA sequencing method. Results: The individual SNPs analysis showed the +869T and -509C in an additive model (+869T vs +869C; -509 C vs T), +869TT genotype in a recessive model (TT vs TC+CC) and 509CC genotype in a dominant model (CC+ CT vs TT) were identified to be related to CI (P<0.05). +869T>C and -509C>T SNPs were in strong linkage disequilibrium (d'=0.87, R2=0.75). Haplotype analysis showed that +869C/-509T haplotype was associated with a significant decreased risk of CI (OR= 0.86, 95%CI, 0.70-0.92; P=0.007). Furthermore,+869T/-509C haplotype was associated with a significant increased risk of CI (OR=1.31, 95%CI, 1.10-2.03; P=0.019). Conclusions: The results of this study indicate that polymorphisms and the haplotypes in the TGFβ1 gene might be genetic markers for CI in the Chinese population.

The aim of this study was to investigate the effect of vascular endothelial growth factor-C (VEGF-C) expression in tumor-associated macrophages (TAMs) on lymphatic microvessel density (LMVD) and lymphatic endothelial cell proliferation (LECP) and to determine the role of VEGF-C expression in lymphangiogenesis in patients with breast cancer. Breast cancer tissue specimens confirmed by pathological analysis were obtained from 75 patients. Samples were observed by microscopy analysis after immunohistochemical double-staining. The total number of TAMs and the number of VEGF-C-positive TAMs were determined. LMVD and LECP were calculated for the intratumoral and peritumoral areas. Correlation analysis was performed among these indexes, lymph vessel invasion (LVI) and lymph node metastasis in the peritumoral regions. Immunohistochemical double-staining demonstrated that VEGF-C was markedly expressed in TAMs. The number of TAMs, LMVD and LECP in the peritumoral areas was significantly higher than that in the intratumoral areas (P<0.001). We observed positive correlations between the following parameters: the number of TAMs and the peritumoral LMVD (P<0.001), the percentage of TAMs expressing VEGF-C and the peritumoral LMVD (P<0.001), the number of TAMs and the peritumoral LECP (P<0.001), and the percentage of TAMs expressing VEGF-C and the peritumoral LECP (P<0.001). Furthermore, the total number of TAMs and VEGF-C-positive TAMs, LMVD and LECP in cases with lymph node metastasis or LVI were significantly higher compared to those in cases without lymph node metastasis or LVI (P<0.01 or P<0.05). Our findings suggest that TAMs play a critical role in tumor-induced lymphangiogenesis through upregulating VEGF-C, which may contribute to lymphatic invasion in breast cancer.

Objective: In this paper, we focus on three aspects: (1) to annotate a set of standard corpus in Chinese discharge summaries; (2) to perform word segmentation and named entity recognition in the above corpus; (3) to build a joint model that performs word segmentation and named entity recognition. Design: Two independent systems of word segmentation and named entity recognition were built based on conditional random field models. In the field of natural language processing, while most approaches use a single model to predict outputs, many works have proved that performance of many tasks can be improved by exploiting combined techniques. Therefore, in this paper, we proposed a joint model using dual decomposition to perform both the two tasks in order to exploit correlations between the two tasks. Three sets of features were designed to demonstrate the advantage of the joint model we proposed, compared with independent models, incremental models and a joint model trained on combined labels. Measurements: Micro-averaged precision (P), recall (R), and F-measure (F) were used to evaluate results. Results: The gold standard corpus is created using 336 Chinese discharge summaries of 71 355 words. The framework using dual decomposition achieved 0.2% improvement for segmentation and 1% improvement for recognition, compared with each of the two tasks alone. Conclusions: The joint model is efficient and effective in both segmentation and recognition compared with the two individual tasks. The model achieved encouraging results, demonstrating the feasibility of the two tasks.

To evaluate the efficacy and safety of Pai-Neng-Da Capsule (panaxadiol saponins component, PND), a new Chinese patent medicine, on patients with chronic aplastic anemia (CAA) and to explore the optimal therapeutic regimen for CAA.A total of 36 patients with CAA were enrolled and divided into three groups: the AP group (20 cases, andriol 120 mg/day + PND 240 mg/day), the ACP group (13 cases, andriol 120 mg/day + cyclosporine 3-6 mg kd(-1) day(-1) + PND 240 mg/day), and the PND group (3 cases, PND 240 mg/day). All patients were treated and followed up for 6 months. Peripheral blood counts, renal and hepatic function and Chinese medical (CM) symptoms of patients were assessed and all indices were gathered at the beginning and end of the study.In the AP group, no significant hematologic difference was observed at the end of 6-month treatment comparing with the beginning. In the ACP group, the blood counts were maintained at the same level after the 6-month treatment. In the PND group, trilineage hematologic improvement was displayed at the end of 6-month treatment comparing with the beginning. No significant difference was showed in renal and hepatic function in all patients. All patients clinical symptom improved according to CM symptom score. The effective rates were 95%, 73% and 100%, respectively.PND improved the efficacy and decreased side effects by cutting down the dosage of andriol, and it could also improve patients clinical symptom and quality of life. PND were effective and safe in the treatment of CAA, it could be used alone or in combination with pharmacological agents such as andriol and cyclosporine.

Objective: To explore the myoblast formation around the urethra and increase in urethral resistance of bone marrow mesenchymal stem cells or muscle-like cells/calcium alginate composite gel injection therapy and effect on LPP in SUI rat model. Methods: Isolation, cultivation, and identification of SD rat bone marrow mesenchymal stem cell were performed. 5-Azacytidine was introduced to induce muscle-like cells. SUI was produced in 72 6-week-old female Sprague-Dawley rats, which were divided into four groups: stem cell-gel group, muscle-like cell-gel group, Gel group, and mock control group. One, 4, and 8 weeks after injection, the leak point pressure (LPP) was measured. HE staining of Desmin and α-skeletal muscle actin (α-SMA) were performed. Results: At 4 and 8 weeks after injection in stem cell-gel group and muscle-like cell-gel group, growth of blood vessels gradually increased at gel edge, BMSC, and muscle-like cells gathered around the new blood vessels observed by fluorescence tracer, muscle-like cells grew into elongated spindle-like cells, Desmin, and α-SMA staining were obviously positive expression. LPP determinations of the mock control group compared with the Gel groups were significantly different. Conclusions: Compound of BMSC, muscle-like cells, and calcium alginate composite gel has the potential to differentiate into muscle cells in the microenvironment of SUI rat model. It is found by LPP measurement that the correlation between the increase in urethral resistance and the volume effect of calcium alginate gel is high. © 2012 Wiley Periodicals, Inc.

The pro-inflammatory cytokine interleukin-6 (IL-6) in tumor microenvironment has been suggested to promote development and progression of colorectal cancer (CRC). However, the underlying molecular mechanisms remain elusive. In this study, we demonstrate that fos-related antigen-1 (Fra-1) plays a critical role in IL-6 induced CRC aggressiveness and epithelial- mesenchymal transition (EMT). In CRC cell lines, the expression of Fra-1 gene was found significantly upregulated during IL-6-driven EMT process. The Fra-1 induction occurred at transcriptional level in a manner dependent on signal transducer and activator of transcription 3 (STAT3), during which both phosphorylated and acetylated post-translational modifications were required for STAT3 activation to directly bind to the Fra-1 promoter. Importantly, RNA interference-based attenuation of either STAT3 or Fra-1 prevented IL-6-induced EMT, cell migration and invasion, whereas ectopic expression of Fra-1 markedly reversed the STAT3-knockdown effect and enhanced CRC cell aggressiveness by regulating the expression of EMT-promoting factors (ZEB1, Snail, Slug, MMP-2 and MMP-9). Furthermore, Fra-1 levels were positively correlated with the local invasion depth as well as lymph node and liver metastasis in a total of 229 CRC patients. Intense immunohistochemical staining of Fra-1 was observed at the tumor marginal area adjacent to inflammatory cells and in parallel with IL-6 secretion and STAT3 activation in CRC tissues. Together, this study proposes the existence of an aberrant IL-6/STAT3/Fra-1 signaling axis leading to CRC aggressiveness through EMT induction, which suggests novel therapeutic opportunities for the malignant disease. © The Author 2015.

Background: Some areas of laparoscopic splenectomy (LS), such as the approach to splenic pedicle dissection, remain controversial. Here we recommend a technique for dissecting the secondary splenic pedicle vessels on the basis of analysis of retrospective data. Study Design: A retrospective review (April 2006 to October 2011) of databases at 2 institutions identified 136 patients who had undergone LS. In 34 patients with massive splenomegaly, primary splenic pedicle dissection technique (PSPD) had been used in 19 patients and secondary splenic pedicle dissection technique (SSPD) had been used in 15 patients. In 102 patients with normal-sized spleen or moderate splenomegaly, PSPD had been used in 56 patients and SSPD in 46 patients. We compared perioperative and follow-up data. Results: Laparoscopic splenectomy was completed in 128 patients. In the massive splenomegaly group, the conversion rate was 5.3% for PSPD and 33.3% for SSPD, the complication rate was 42.1% vs 20%, hospital stay was 3.2 ± 2.0 days vs 7.5 ± 3.5 days, and transfusion requirement was 1.1 ± 1.2 U vs 3.2 ± 0.9 U, respectively. However, in the normal or moderate splenomegaly group, except for complications, there were no significant differences between PSPD and SSPD techniques in perioperative findings. In the 2 groups, there were significant differences between the PSPD and SSPD techniques in pancreatic leakage (15.8% vs 0 and 8.9% vs 0, respectively) and postoperative fever (15.8% vs 6.7% and 10.7% vs 2.2%, respectively). Conclusions: Secondary splenic pedicle dissection can decrease the incidence of splenic fever and pancreatic leakage and is a valuable technique for LS for normal-sized spleen or moderate splenomegaly. It is not a safe procedure for massive splenomegaly because of the high conversion rate. © 2013 by the American College of Surgeons.

AIM: To assess the efficacy of Mamiai in the prevention of childhood diarrhea secondary to pneumonia. METHODS: One hundred and eight children with pneumonia treated at Ling’an People’s Hospital from January 2013 to January 2015 were randomly divided into either an observation group or a control group, with 54 cases in each group. The control group was given symptomatic treatment (e.g., antibiotic therapy), and the observation group was additionally given Mamiai on the basis of symptomatic treatment. The total duration of diarrhea, time to diarrhea control, hospitalization time, and the incidences of abdominal pain, diarrhea, tenderness, loss of appetite, dehydration, and abnormal bowel sounds were compared for the two groups. RESULTS: The total duration of diarrhea, time to diarrhea control, and hospitalization time were significantly shorter in the observation group than in the control group (P < 0.05). The incidences of abdominal pain, diarrhea, tenderness, loss of appetite, dehydration, and abnormal bowel sounds were significantly lower in the observation group than in the control group (P < 0.05). CONCLUSION: Mamiai can better prevent childhood diarrhea secondary to pneumonia, reduce hospitalization time and duration, and has high security. © 2015 Baishideng Publishing Group Inc.

Objective: To investigate the effects of icariin on cardiac functions and mitochondrial oxidative stress in streptozotocin (STZ)-induced diabetic rats. Method: Male SD rats were randomly divided into normal control group, icariin control group, diabetic group, and diabetic groups administered with a low dose (30 mL·kg -1·d -1, ig) or a high dose (120 mL·kg -1·d -1, ig) of icariin for 8 weeks. The body weight, blood glucose, cardiac functions, left ventricular weight, and myocardial collagen level were assayed. The cardiac mitochondrial reactive oxygen species (ROS) level, malondialdehyde (MDA) level, and superoxide dismutase (SOD) activity were measured. Result: Treatment with icariin reduced the losing of body weight in diabetic rats. Icariin markedly reduced the ratio of ventricular weight and body weight, increased the left ventricular develop pressure and ±dp/dt max, and decreased the left ventricular end diastolic pressure in diabetic rats. The myocardial collagen and the level of cardiac mitochondrial ROS in diabetic rats were all markedly reduced by icariin. Furthermore, high dose of icariin significantly decreased the mitochondrial MDA level and increased SOD activity in diabetic rat hearts. Conclusion: Treatment with icariin for 8 weeks markedly improved the cardiac function, which may be related to reducing mitochondrial oxidative stress injuries in diabetic rats.
