Abstract
The matrix glycoprotein thrombospondin-1 (THBS1) modulates nitric oxide (NO) signaling in endothelial cells. A high-salt diet induces deficiencies of NO production and bioavailability, thereby leading to endothelial dysfunction. In this study we investigated the changes of THBS1 expression and its pathological role in the dysfunction of mesenteric artery endothelial cells (MAECs) induced by a high-salt diet. Wild-type rats, and wild-type and Thbs1-/- mice were fed chow containing 8% w/w NaCl for 4 weeks. We showed that a high salt diet significantly increased THBS1 expression and secretion in plasma and MAECs, and damaged endothelium-dependent vasodilation of mesenteric resistance arteries in wild-type animals, but not in Thbs1-/- mice. In rat MAECs, we demonstrated that a high salt environment (10-40 mM) dose-dependently increased THBS1 expression accompanied by suppressed endothelial nitric oxide synthase (eNOS) and phospho-eNOS S1177 production as well as NO release. Blockade of transforming growth factor-β1 (TGF-β1) activity by a TGF-β1 inhibitor SB 431542 reversed THBS1 up-regulation, rescued the eNOS decrease, enhanced phospho-eNOS S1177 expression, and inhibited Smad4 translocation to the nucleus. By conducting dual-luciferase reporter experiments in HEK293T cells, we demonstrated that Smad4, a transcription promoter, upregulated Thbs1 transcription. We conclude that THBS1 contributes to endothelial dysfunction in a high-salt environment and may be a potential target for treatment of high-salt-induced endothelium dysfunction.

Abstract
The purpose of this study is to assess the clinical significance of the radiologic safe zone based on computed tomography and to compare the outcomes of three different implants for fixation of isolated radial head fractures. We retrospectively reviewed 367 patients who underwent internal fixation for isolated radial head fractures. We newly defined two subtypes of Mason type II fractures associated with the radiographic safe zone (IIA, two-part fracture allowing for safe fixation of plate; IIB, two-part fracture not allowing for safe fixation). 170 patients (CCS group, n = 82; HCS group, n = 31; plate group, n = 57) were investigated with no significant differences in demographics. The range of pronation and supination at 1 month postoperatively (P = 0.04 and P = 0.04) and the range of supination at 6 and 12 months postoperatively (P = 0.03 and P = 0.03) were significantly smaller in the plate group. In Mason type IIB fractures, the average MEPS was higher in the CCS and HSC groups than in the plate group (P = 0.01 and P = 0.02). And the average DASH score was lower in the CCS and HCS groups (P < 0.01 and P < 0.01). Evaluation of the radiologic safe zone is potentially helpful in selecting better surgical fixation option. For type III fractures, 2.3-mm cortical screws would be a better option than Acutrak screws. Plates would not be suitable for type IIB radial head fractures.

Abstract
Lampriform fishes (Lampriformes), which primarily inhabit deep-sea environments, are large marine fishes varying from the whole-body endothermic opah to the world's longest bony fish-giant oarfish, with species morphologies varying from long and thin to deep and compressed, making them an ideal model for studying the adaptive radiation of teleost fishes. Moreover, this group is important from a phylogenetic perspective owing to their ancient origins among teleosts. However, knowledge about the group is limited, which is, at least partially, due to the dearth of recorded molecular data. This study is the first to analyze the mitochondrial genomes of three lampriform species (Lampris incognitus, Trachipterus ishikawae, and Regalecus russelii) and infer a time-calibrated phylogeny, including 68 species among 29 orders. Our phylomitogenomic analyses support the classification of Lampriformes as monophyletic and sister to Acanthopterygii; hence, addressing the longstanding controversy regarding the phylogenetic status of Lampriformes among teleosts. Comparative mitogenomic analyses indicate that tRNA losses existed in at least five Lampriformes species, which may reveal the mitogenomic structure variation associated with adaptive radiation. However, codon usage in Lampriformes did not change significantly, and it is hypothesized that the nucleus transported the corresponding tRNA, which led to function substitutions. The positive selection analysis revealed that atp8 and cox3 were positively selected in opah, which might have co-evolved with the endothermic trait. This study provides important insights into the systematic taxonomy and adaptive evolution studies of Lampriformes species.

Abstract
We report the first (in)elastic scattering measurement of ^{25}Al+p with the capability to select and measure in a broad energy range the proton resonances in ^{26}Si contributing to the ^{22}Mg(α,p) reaction at type I x-ray burst energies. We measured spin-parities of four resonances above the α threshold of ^{26}Si that are found to strongly impact the ^{22}Mg(α,p) rate. The new rate advances a state-of-the-art model to remarkably reproduce light curves of the GS 1826-24 clocked burster with mean deviation <9% and permits us to discover a strong correlation between the He abundance in the accreting envelope of the photospheric radius expansion burster and the dominance of ^{22}Mg(α,p) branch.

Abstract
INTRODUCTION Fingolimod, a sphingosine-1-phosphate modulator used in the treatment of relapsing-remitting multiple sclerosis, has been associated with several cases of cryptococcosis. CASE REPORT We present a case of Cryptococcal meningoencephalitis attributable to Cryptococcus neoformans var. grubii, in a 58-year-old bird-keeper from Australia, after 7 years of fingolimod therapy. We discuss this in the context of previously reported cases, our understanding of fingolimod immune modulation, and known Cryptococcus pathobiology. CONCLUSION We suggest consideration of harm minimisation behaviours in patients requiring fingolimod, particularly in those with profound CD4 lymphopenia. Furthermore, we echo the call for improved post-marketing surveillance systems to determine the epidemiology of atypical infections with novel immunomodulatory treatments.

Abstract
Objective: To understand the genotype distribution of Mycobacterium tuberculosis and the drug susceptibility of M. tuberculosis with different genotypes in Changping district of Beijing and evaluate the application of genotyping of M. tuberculosis in local tuberculosis (TB) prevention and control. Methods: A total of 1 099 M. tuberculosis strains isolated in Changping from 2011 to 2015 were used. Spoligotyping and 12-locus VNTR recommended by Gao were used for the genotyping of these isolates. In addition, the susceptibility of the M. tuberculosis isolates to rifampin (RFP), isoniazid (INH), ethambutol (EMB), streptomycin (SM), amikacin (AMK) and ofloxcin (OFX) were detected by using conventional drug susceptibility test. Results: From 2011 to 2015, the detection rate of OFX-resistance increased from 2.9% to 8.9% (P=0.01). Of all the M. tuberculosis isolates, 976 belonged to Beijing genotype (88.8%), and the other 123 belonged to non-Beijing genotype (11.2%). In addition, there were 189 ancient Beijing genotype isolates and 787 modern Beijing genotype isolates, respectively. The proportion of Beijing genotype strains showed no significant increase in the past five years (81.1% in 2011 vs. 82.0% in 2015). On the basis of VTNR genotyping, only 2 isolates belonged to one cluster (0.1%). In addition, the AMK resistant rate of Beijing genotype strains (1.7%) was significantly lower than that of non-Beijing genotype strains (4.9%, P=0.02). Compared with modern Beijing genotype strains, the SM resistant rate of ancient Beijing genotype strains was significantly higher (28.0% vs. 15.7%, P=0.01). Conclusions: In the past five years, the OFX- resistant rate of M.tuberculosis in Changping was in increase. There was no significant difference in the detection of Beijing genotype strains during this period. In addition, the low clustering rate indicated that the TB transmission rate was low in Changping.

Abstract
Objective:To explore the possibility of endoscopic nasolacrimal duct decompression surgery for the treatment of chronic dacryocystitis.Method:①Twenty-two eyes with chronic dacryocystitis were treated with 30% iohexol injection for lacrimal sac lithography. Contrast agents were taken from the lacrimal canal reflux to stop the injection. The CT scan for the lacrimal passage was performed immediately. ②Three-dimensional reconstruction of lacrimal duct and its surrounding structures was performed with Sinuses Trachea Ⅰ software. ③The lacrimal sac and nasolacrimal canal were cut and depressed using this software simulation.Result:①The incidence of lacrimal duct obstruction were 4.5% (1/22, in lacrimal duct), 22.7%(5/22, in lacrimal sac), 13.6%(3/22, transition section), 36.4%(8/22, in nasocrimal duct), and 22.7%(5/22, in Hasner valve) separately. The transitional section, nasolacrimal duct, Hasner valve section 72.7%(16/22) totally. ②The lateral wall of the nasolacrimal duct in 3D visual model is constructed of maxillary lacrimal process. The interior wall of the nasolacrimal duct is made of drop process of lacrimal bone and ascending lacimal process of the inferior turbinate. ③Observed from the inferior meatus, hard nasolacrimal duct is surrounded by inferior turbinate bone, and forms the inside wall of openings of the lacrimal duct. ④The removal of the front parts of the inferior turbinate attached to the lateral nasal can lead to the deperession of the membranous nasolacrimal duct sufficiently, and create the efficient space to eliminate nasolacrimal duct obstruction. Conclusion:Endoscopic nasolacrimal duct decompression surgery is efficacy for the treatment of chronic dacryocystitis. The integrity of the membranous lacrimal duct was reserved, and the complication such as lacrimal sac granulation hyperplasia, lacrimal duct obstruction again caused by scar formation was avoided.

Abstract
OBJECTIVE To investigate the expression and its significance of tumor necrosis factor-alpha (TNF-alpha) and caspase-3 protein in monocytes adjacent to the invaded Echinococcus multilocularis in liver. METHODS 40 female Kunming mice were randomly divided into experimental group (n=20) and sham operation (control) group (n=20). Mice in experimental group were infected with 20% E. multilocularis suspension (0.1 ml per mouse) through abdominal opening injection in liver and the mice in control group were injected with equal physiological saline. The mice were sacrificed at 6 months post-infection for observing the growth and metastasis of E. multilocularis. Pathological changes were observed by HE staining. The expression of TNF-alpha and caspase-3 protein in hydatid cyst and metastasis tissue were detected by immunohistochemistry staining and the apoptosis of the monocytes was measured by TUNEL. RESULTS After 6 months post-infection, E. multilocularis were spread over the liver of the mice in experimental group. Metastasis rate of lymph nodes was 45.0% (9/20). Infiltration of monocytes was observed around E. multilocularis in liver and lymph nodes with metastasis by HE staining. Immunohistochemistry showed that the positive expression rate of TNF-alpha and caspase-3 protein in monocytes was 100% and 100%, and 95% and 100% respectively around the cyst in experimental group, while the expression rate was only 5% and 0 respectively in the liver of the control mice (P<0.01). The monocytes showed significant apoptosis by TUNEL in experimental group with a positive expression rate of 100%, with a significant difference between experiment group and the control (P<0.01). CONCLUSION In the process of alveolar Echinococcus infection, the high expression of TNF-alpha protein might be associated with the apoptosis of monocytes, which may inhibit the host immunological function.

Abstract
An epidemiological survey of blood pressure was carried out in 2301 pre-schoolers aged 2-6 years in 11 kindergartens of Guangzhou during 1984. Judging from the chart of selected percentile of blood pressure in relation to age plotted according to the mean blood pressure, the authors suggest that the upper limit of pre-schoolers' blood pressure is 115/75 mmHg. The blood pressure of growing children rises with increases in age, weight and height. Ponderosity Index (W/H3) reflects more precisely the influence of body weight and height on blood pressure. The results show that the percentage of children with high normal pressure is obviously higher in those with a family history of hypertension than in those without such a history. It is of great importance, in the prevention of primary hypertension, to practise medical surveillance and health care in children with high normal blood pressure, especially in those with a family history of hypertension.
