Background: Bevacizumab and triamcinolone acetonide (TA) are both common choices for treatment of diabetic macular edema (DME), but the comparative efficacy of combined or separate applications is still not determined. Objectives: To compare the treatment efficacy of intravitreal bevacizumab (IVB) and the combination of IVB and intravitreal triamcinolone (IVT) for DME patients. Methods: PubMed, EMBASE, and the Cochrane library were systematically reviewed for randomized controlled trials comparing IVB with IVB/IVT. Data on visual acuity (VA) and central macular thickness (CMT) changes at 3 and 6 months were extracted and data on adverse events were collected. A meta-analysis was performed using the software RevMan 5.3. The methodological quality and bias risks were also evaluated. Results: VA improved more significantly in the IVB/IVT group compared with the IVB group at 3 months (mean difference [MD] = 0.07; 95% CI = 0.01 to 0.13), whereas there was no significant difference at 6 months (MD = −0.01; 95%CI = −0.11 to 0.09). The CMT reduction in the IVB/IVT group was significantly greater than that in the IVB group at 3 months (MD = 48.40; 95%CI = 30.23 to 66.57), but no statistically significant difference was found at 6 months (MD = 0.47; 95%CI = −24.11 to 25.04). Ocular hypertension was detected in 9/243 eyes in the IVB/IVT group but none of the IVB eyes. Conclusion: IVB/IVT is more effective for improving VA and decreasing CMT at 3 months in DME. A single injection of TA along with the first IVB could improve outcome within 3 months, but this is not sustained at 6 months. Continuous IVT/IVB treatment should be performed in further trials to clarify its long-term potential efficacy. © The Author(s) 2015

Gastric cancer (GC) is a very common disease worldwide where new serum biomarkers are urgently needed to improve their early diagnosis. In this study, we aim to search for the potential serum protein/peptide biomarkers of GC by using surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS). We first obtained the serum protein/peptide profiles from a training dataset including 30 patients with GC, 16 cases with chronic benign gastric disease (CGD), and 30 normal controls (CON) where 15 protein peaks were identified to exhibit the obvious deviation (P<0.001, Wilcoxon rank sum test) among GC, CGD, and CON analyzed by Biomarker Wizard 3.1 software with three protein peaks with mass-to-charge (m/z) ratio 5910, 5342, and 6439 further confirmed in the validation dataset. Among the three protein peaks, peak 5910 displayed the most significantly different which could distinguish GC patients from CGD and CON with a sensitivity of 86.3%, a specificity of 91.3%, and the area under the receiver operating characteristic curve (AUC) of 0.89 by using the optimal cutoff value of 17.3. We further identified peak 5910 as the carboxyl terminal fraction of Fibrinogen by LC-MS and validated its identity by antiserum-mediated SELDI-based immunodepletion assays. In sum, SELDI-TOF-MS method could effectively generate serum peptidome in cancer patients and provide a new approach to identify potentially diagnostic and prognostic biomarkers for cancer. The carboxyl terminal fraction of Fibrinogen may be a potential serological biomarker for GC diagnosis.

Problem: Epididymitis, one of the most common urological diseases, can lead to the destruction of the epididymal duct and cause transient or permanent sterility. The aim of this study was to investigate the functions and related mechanisms of all trans retinoic acid (atRA) in alleviating the acute inflammation of epididymitis. Method of study: The mouse model of the epididymitis was induced by injecting Escherichia coli into the cauda epididymis. atRA was administrated for five consecutive days through intraperitoneal injection. The expression levels of inflammatory cytokines were measured by real-time PCR and Western blot. In addition, cultured primary mouse epididymal epithelial cells were treated with different concentrations of atRA and RAR antagonists to identify whether the effect of atRA was mediated through RAR. Results: Our results demonstrate that atRA ameliorates the inflammation in mouse epididymitis by decreasing the expression of the pro-inflammatory cytokines and increasing the expression of anti-inflammatory factors including TGF-β1 and IL-10. Our results show that the upregulating effect of atRA on TGF-β1 was mediated by RARα, and the enhancing effect of atRA on IL-10 expression was mediated via RARβ. Conclusion: These new results suggest that atRA is involved in regulating the inflammatory response of epididymis. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The surgical treatment of cavernous malformations involving the posterior limb of the internal capsule (PLIC-CMs) is challenging. The aim of this study was to determine the utility and predictive value of preoperative diffusion tensor imaging (DTI) in the surgical treatment of PLIC-CMs.Patients with PLIC-CMs who were surgically treated between September 2012 and June 2015 were reviewed. All patients underwent preoperative DTI. Three major fiber tracts were selected for evaluation: 1) corticospinal tract (CST); 2) arcuate fasciculus (AF); and 3) optic radiation (OR). The utility of preoperative DTI for surgical approach selection and intraoperative navigation was documented. An involvement grading system of the major fibers was applied to determine the predictive value of preoperative DTI. A last modified Rankin Scale (mRS) score of 0-2 was considered a good outcome, and a last mRS >2 was considered a poor outcome.Thirteen patients with 13 PLIC-CMs were reviewed in this study. All the lesions were radically resected via the corridor formed by CST, AF, and OR. None of the patents suffered from mRS >3, and 7 patients (53.8%) got good outcomes at the last clinic visit. The difference between the preoperative mRS scores and last mRS scores was not significant (P= 0.673). The involvement grade of the fiber tracts was significantly associated with the surgical outcome (P= 0.011).Preoperative DTI may be a promising tool to determine the surgical approach and predict the surgical outcomes in patients with PLIC-CMs.

The aim of this study was to investigate associations between single nucleotide polymorphisms rs13301537 in asporin (ASPN) and rs373444 in the bone morphogenetic protein 5 (BMP5) gene with knee osteoarthritis (OA) susceptibility in a Chinese Han population. ASPN rs13301537 and BMP5 rs373444 polymorphisms were genotyped in patients with knee OA and age- and sex-matched OA-free controls from a Chinese Han population. A total of 510 patients with knee OA and 520 controls were enrolled in the study. CT and CC genotypes of rs13301537, and variant C, were associated with a significantly increased risk of knee OA. On stratification analysis, the association between the risk of OA and rs13301537 CT heterozygotes compared with TT homozygotes was stronger in females and those aged >65 years. In contrast, the CT and CC genotypes of rs373444 in BMP5 were not significantly associated with the risk of knee OA, even after further stratification analysis according to age or sex. Our results showed that ASPN rs13301537 T to C change and variant C genotype may contribute to knee OA risk in a Chinese Han population. © 2014, Springer Science+Business Media New York.

Heat shock protein A 12B (HSPA12B) is a newly discovered member of the heat shock protein 70 family. Preclinical evidence indicates that HSPA12B helps protect the brain from ischemic injury, although its specific function remains unclear. The aim of this study is to investigate whether HSPA12B overexpression can protect astrocytes from oxygen-glucose-serum deprivation/restoration (OGD/R) injury. We analyzed the effects of HSPA12B overexpression on spinal cord ischemia-reperfusion injury and spinal astrocyte survival. After ischemia-reperfusion injury, we found that HSPA12B overexpression decreased spinal cord water content and infarct volume. MTT assay showed that HSPA12B overexpression increased astrocyte survival after OGD/R treatment. Flow cytometry results showed a marked inhibition of OGD/R-induced astrocyte apoptosis. Western blot assay showed that HSPA12B overexpression significantly increased regulatory protein B-cell lymphocyte 2 (Bcl-2) levels, whereas it decreased expression of the Bax protein, which forms a heterodimer with Bcl-2. Measurements of the level of activation of caspase-3 by Caspase-Glo3/7 Assay kit showed that HSPA12B overexpression markedly inhibited caspase-3 activation. Notably, we demonstrated that the effects of HSPA12B on spinal astrocyte survival depended on activation of the PI3K/Akt signal pathway. These findings indicate that HSPA12B protects against spinal cord ischemia-reperfusion injury and may represent a potential treatment target.

Osteosarcoma is one of the malignant cancers. Improving diagnosis and treatment of this disease is urgent. Microarray data have revealed abnormal expression of several genes implicated in osteosarcoma. From the mRNA data, differentially expressed (DE) genes were selected by Wilcox test. Using Endeavour online service, 200 DE genes were selected as osteosarcoma related genes. Combing the module extraction algorithm, we identified 90 osteosarcoma candidate genes. Nine (DCC, FGFR, Fzd1, NFKBIA, CCNE1, CASP3, APC, and LRP6) out of the 90 candidate genes have great potential roles in osteosarcoma. © Springer International Publishing Switzerland 2015.

OBJECT Case selection for the surgical treatment of arteriovenous malformations (AVMs) of the eloquent motor area remains challenging. The aim of this study was to determine the risk factors for worsened muscle strength after surgery in patients with this disorder. METHODS At their hospital the authors retrospectively studied 48 consecutive patients with AVMs involving motor cortex and/or the descending pathway. All patients had undergone preoperative functional MRI (fMRI) and diffusion tensor imaging (DTI), followed by resection. Both functional and angioarchitectural factors were analyzed with respect to the change in muscle strength. Functional factors included lesion-to-corticospinal tract distance (LCD) on DTI and lesion-to-activation area distance (LAD) and cortical reorganization on fMRI. Based on preoperative muscle strength, the changes in muscle strength at 1 week and 6 months after surgery were defined as short-term and long-term surgical outcomes, respectively. Statistical analysis was performed using the statistical package SPSS (version 20.0.0, IBM Corp.). RESULTS Twenty-one patients (43.8%) had worsened muscle strength 1 week after surgery. However, only 10 patients (20.8%) suffered from muscle strength worsening 6 months after surgery. The LCD was significantly correlated with short-term (p < 0.001) and long-term (p < 0.001) surgical outcomes. For long-term outcomes, patients in the 5 mm LCD > 0 mm (p = 0.009) and LCD > 5 mm (p < 0.001) categories were significantly associated with a lower risk of permanent motor worsening in comparison with patients in the LCD = 0 mm group. No significant difference was found between patients in the 5 mm LCD > 0 mm group and LCD > 5 mm group (p = 0.116). Nidus size was the other significant predictor of short-term (p = 0.021) and long-term (p = 0.016) outcomes. For long-term outcomes, the area under the ROC curve (AUC) was 0.728, and the cutoff point was 3.6 cm. Spetzler-Martin grade was not associated with short-term surgical outcomes (0.143), although it was correlated with long-term outcomes (0.038). CONCLUSIONS An AVM with a nidus in contact with tracked eloquent fibers (LCD = 0) and having a large size is more likely to be associated with worsened muscle strength after surgery in patients with eloquent motor area AVMs. Surgical treatment in these patients should be carefully considered. In patients with an LCD > 5 mm, radical resection may be considered to eliminate the risk of hemorrhage.

To study the change of the blood coagulation function of guinea pigs exposed to 16 Hz/120 dB, 16 Hz/125 dB infrasound and to explore the mechanism of circulation system damage. Seventy-two guinea pigs were divided into 3 groups: the control group, the group exposed to 16 Hz/120 dB infrasound for 1.5 h a day and the group exposed to 16 Hz/125 dB infrasound for 1.5 h a day. Each exposure group was divided into 4 sub-groups (8 guinea pigs a sub-group) which were exposed to infrasound for 1, 7, 14 and 21 d, respectively. The coagulation function and serum nitric oxide (NO) were measured for control group and all sub-groups after exposure to infrasound. The prothrombin time (PT), international normalized ratio (INR) and serum NO of group exposed to 16 Hz/125 dB infrasound were (31.16 ± 3.05) s, 2.53 ± 1.21 and (88.304 ± 52.601) μmol/L, respectively, which were significantly higher than those [(21.36 ± 0.10) s, 1.65 ± 0.07 and (30.943 ± 26.864) μmol/L] of control group (P < 0.05). PT and INR of sub-groups exposed to 16 Hz/125 dB infrasound for 14 and 21 d were significantly higher than those of control group. NO of sub-groups exposed to 16 Hz/125 dB infrasound for 1 week and 2 weeks were significantly higher than that of control group (P < 0.05), but NO of sub-group exposed to 16 Hz/125 dB infrasound for 3 weeks decreased slightly. The blood coagulation function of guinea pigs exposed to 16 Hz/125 dB infrasound decreased, PT and INR may be used as the indexes to assess of blood coagulation function change induced by the infrasound exposure.

To explore the expression of phosphorylated STAT3 (pSTAT3) in non-small cell lung cancer(NSCLC) and its clinical significance. The expression of pSTAT3 was detected in 59 cases of NSCLC and their para-cancerous tissue by immunohistochemical staining. (1) The expression of pSTAT3 in NSCLC was significantly higher than that in para-cancerous tissue. (2) The expression of pSTAT3 was associated with tumor's size and smoking status, which was significantly higher in smaller tumors(diameter<3 cm) and nonsmokers than that in larger tumors(diameter≥3 cm) and smokers, but was not associated with gender, age, lymph node metastasis, clinical stage and differentiation grade. The percentage rate of pSTAT3 expression was higher in adenocarcinoma than that in squamous cell carcinoma but without statistically significant. pSTAT3 may play an important role in the development of NSCLC and the direction of targeted therapy.
