Abstract
AIM Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was reported to be useful for diagnosis of tuberculosis (TB) lymphadenitis, although its indication remains unclear for suspicious pulmonary TB patients. To clarify the role of EBUS-TBNA for the diagnosis of immunocompetent TB patients with intrathoracic lymphadenopathy, we compared two diagnostic modalities: traditional bronchoscopy alone and EBUS-TBNA combined with bronchoscopy. METHODS We retrospectively studied 175 patients of suspicious pulmonary TB with intrathoracic lymphadenopathy in a single institute (Tongji University, Shanghai, China) from January 2010 to May 2011. RESULTS Ninety-seven patients underwent traditional bronchoscopy alone while 78 received the combined diagnostic techniques. Sensitivity and specificity were 18.1% and 100%, respectively, in the bronchoscopy group alone, and 80% and 92.3%, respectively, in the EBUS-TBNA combination group (absolute increase in sensitivity, 61.9%; P<0.001; 95% CI, 48.7-75.1%). In the combination group, EBUS-TBNA alone was diagnostic of TB in 42 patients (64.6%, 95% CI, 53-76.2%). Bleeding without hemodynamic instability developed in two patients during the procedure of EBUS-TBNA and no hospitalization prolongation happened in the both arms. CONCLUSION Combination of EBUS-TBNA with standard bronchoscopic technique is safe and significantly increases the diagnostic yield in patients of suspicious pulmonary TB with lymphadenopathy.

Abstract
A network of heat-shock proteins mediates cellular protein homeostasis, and has a fundamental role in preventing aggregation-associated neurodegenerative diseases. In a Drosophila model of polyglutamine (polyQ) disease, the HSP40 family protein, DNAJ-1, is a superior suppressor of toxicity caused by the aggregation of polyQ containing proteins. Here, we demonstrate that one specific HSP110 protein, 70 kDa heat-shock cognate protein cb (HSC70cb), interacts physically and genetically with DNAJ-1 in vivo, and that HSC70cb is necessary for DNAJ-1 to suppress polyglutamine-induced cell death in Drosophila. Expression of HSC70cb together with DNAJ-1 significantly enhanced the suppressive effects of DNAJ-1 on polyQ-induced neurodegeneration, whereas expression of HSC70cb alone did not suppress neurodegeneration in Drosophila models of either general polyQ disease or Huntington's disease. Furthermore, expression of a human HSP40, DNAJB1, together with a human HSP110, APG-1, protected cells from polyQ-induced neural degeneration in flies, whereas expression of either component alone had little effect. Our data provide a functional link between HSP40 and HSP110 in suppressing the cytotoxicity of aggregation-prone proteins, and suggest that HSP40 and HSP110 function together in protein homeostasis control.

Abstract
OBJECTIVE Studies have demonstrated the protective effects of biomaterials against myocardial infarction (MI), but the relationship between their physical characteristics and their function is incompletely understood. This study investigated such relationships for a hydrogel preparation. METHODS Two types of poly(N-isopropylacrylamide) (PNIPAAm) hydrogel with different degradation times (Gel A and Gel B) were synthesized. In vivo hydrogel formation and maintenance were observed and confirmed in mice. The solutions were also injected into the infarct area immediately after MI induction in rats. RESULTS PNIPAAm hydrogel exhibited a three-dimensional structure resembling native extracellular matrix (ECM). Compared with phosphate-buffered saline, Gel A and Gel B increased contractility of isolated infarcted myocardium, reduced collagen deposition, increased neovascularization, inhibited left ventricle expansion and improved cardiac function. Myocardial contractility was greater with Gel B than with Gel A. CONCLUSIONS Intramyocardial injection of PNIPAAm hydrogel provides structural support and some functional repair of damaged ECM, suggesting that it might be useful for cardiac tissue engineering.

Abstract
BACKGROUND The OPTIMAL study found that erlotinib improved progression-free survival (PFS) versus standard chemotherapy in Chinese patients with advanced EGFR mutation-positive non-small-cell lung cancer (NSCLC). This report describes the quality of life (QoL) and updated PFS analyses from this study. PATIENTS AND METHODS Chinese patients ≥ 18 years with histologically confirmed stage IIIB or IV NSCLC and a confirmed activating mutation of EGFR (exon 19 deletion or exon 21 L858R point mutation) received erlotinib (150 mg/day; n = 82) or gemcitabine-carboplatin (n = 72). The primary efficacy end point was PFS; QoL was assessed using the Functional Assessment of Cancer Therapy-Lung (FACT-L) questionnaire, Trial Outcome Index (TOI) and Lung Cancer Subscale (LCS). RESULTS Patients receiving erlotinib experienced clinically relevant improvements in QoL compared with the chemotherapy group in total FACT-L, TOI and LCS (P < 0.0001 for all scales). Erlotinib scored better than chemotherapy for all FACT-L subscales from baseline to cycles 2 and 4 (non-significant). In the updated analysis, PFS was significantly longer for erlotinib than chemotherapy (median PFS 13.7 versus 4.6 months; HR = 0.164, 95% CI = 0.105-0.256; P < 0.0001), which was similar to the previously reported primary analysis. CONCLUSION Erlotinib improves QoL compared with standard chemotherapy in the first-line treatment of patients with EGFR mutation-positive advanced NSCLC.

Abstract
BACKGROUND Altered Ca(2+) homeostasis contributes significantly to platelet hyperactivity in diabetes mellitus. Calsequestrin (CSQ), as a Ca(2+) buffer protein in the sarcoplasmic reticulum, also regulates the Ca(2+) release process in muscles. We hypothesized that CSQ may be expressed in platelets, but is altered and involved in diabetic platelet Ca(2+) abnormalities and hyperaggregability. METHODS CSQ expression in platelets from streptozotocin-induced type 1 diabetes rats, type 2 diabetes volunteers and Goto-Kakizaki rats were analyzed by western blotting and RT-qPCR. Platelet Ca(2+) and aggregation were evaluated with Fura2 and an aggregometer, respectively. RESULTS Platelets from diabetic patients and rats exhibited increased resting Ca(2+) levels, and hyperactive Ca(2+) and aggregation responses to agonists. This enhanced basal Ca(2+) was largely dependent on intracellular Ca(2+) and insensitive to inositol 1,4,5-trisphosphate receptor (IP(3)R) antagonism. Additionally, the expression of the skeletal CSQ isotype (CSQ-1) was detected in both rat and human platelets, but its levels were significantly lowered in diabetic platelets as compared with normal platelets. Impairment of CSQ by trifluoperazine caused concentration-dependent Ca(2+) release in normal platelets and HEK293 cells. Knocking down CSQ-1 in HEK293 cells resulted in increased leakage of Ca(2+), which was also insensitive to IP(3)R inhibition, and exaggerated Ca(2+) release following carbachol treatment. CONCLUSIONS Downregulation of CSQ-1 in diabetic platelets and impairment of CSQ-1 in normal cells leads to disturbed Ca(2+) release, demonstrating a potential role for CSQ-1 in the regulation of the platelet Ca(2+) release process and a possible causal contribution to diabetic platelet hyperactivity.

Abstract
Narran Lakes is a Ramsar site recognised for its importance for colonial waterbird breeding, which only occurs after large highly variable flooding events. In 2008, 74,095 pairs of ibis bred for the first time in seven years, establishing two contiguous colonies, a month apart. Most (97%) of the colony consisted of the straw-necked ibis (Threskiornis spinicollis) with the remainder consisting of glossy ibis (2%, Plegadis falcinellus) and Australian white ibis (1%, T. molucca). Following cessation of river flows, water levels fell rapidly in the colony site, resulting in a crisis management decision by governments to purchase and deliver water (10,423 Ml) to avert mass desertion of the colonies. There were significant differences in the reproductive success of each colony. In colony 1 60% of eggs hatched and 94% of chicks fledged, while in colony 2 40% of eggs hatched with only 17% of chicks fledging. Statistical analyses found that water depth was a significant variable in determining reproductive success. Rapid falls in water level during the chick stage in colony 2 resulted in decreased chick and overall offspring success. The results of this study identify the impact of upstream water resource development on colonial waterbird breeding and have implications for water management policies.

Abstract
BACKGROUND The effects of recombinant human endostatin, Endostar, combined with concurrent chemo-radiotherapy (CCRT) on tumor growth, angiogenesis and lymphangiogenesis in a mouse xenograft model of cervical cancer was investigated. METHODS HeLa cells were injected subcutaneously to establish mouse xenograft models and mice were treated with normal saline (control), CCRT with cisplatin (CDDP), Endostar, or a combination of Endostar and CCRT. Growth, metastasis, and angiogenesis of tumors was monitored. RESULTS Tumorogenic activity of tumor cells in the CCRT, Endostar and combination Endostar-CCRT treatment groups was markedly decreased compared with the activity in the NS group (p < 0.05). The most significant inhibition of tumor growth was observed in the Endostar with CCRT group. Lymph node metastases in the Endostar with CCRT group (12.5%) and Endostar alone group (25%) were lower compared to the CCRT group (42.8%) and NS group (66.7%; p < 0.05). Endostar was also found to inhibit tumor angiogenesis. Endostar induced apoptosis of HeLa cells in vivo, and inhibited expression of VEGF and HIF-1alpha in vivo and in vitro. CONCLUSION Endostar enhanced the anti-cancer effect of CCRT in a mouse xenograft model of cervical cancer. These findings thus provide a new strategy to treat cervical cancer.
