Abstract
OBJECTIVES HIV self-testing (HIVST) offers an opportunity to increase HIV testing among people not reached by facility-based services. However, the promotion of HIVST is limited as a consequence of insufficient community engagement. We built a social entrepreneurship testing (SET) model to promote HIVST linkage to care among Chinese men who have sex with men (MSM) in Guangzhou. METHODS The SET model includes a few key steps. Each participant first completed an online survey, and paid a US$23 (refundable) deposit to receive an HIVST kit and a syphilis self-testing (SST) kit. After the testing, the results were sent to the platform by the participants and interpreted by Center for Disease Control and Prevention (CDC) staff. Meanwhile, the deposit was returned to each participant. Finally, the Community based organizations (CBO) contacted the participants to provide counselling services, confirmation testing and linkage to care. RESULTS During April-June 2015, a total of 198 MSM completed a preliminary survey and purchased self-testing kits. The majority were aged < 34 years (84.4%) and met partners online (93.1%). In addition, 68.9% of participants had ever been tested for HIV, and 19.5% had ever performed HIVST. Overall, feedback was received from 192 participants (97.0%). Of these participants, 14 people did not use the kits; among those who did use the kits, the HIV and syphilis prevalences were 4.5% (eight of 178) and 3.7% (six of 178), respectively. All of the screened HIV-positive individuals sought further confirmation testing and were linked to care. CONCLUSIONS Using an online SET model to promote HIV and syphilis self-testing among Chinese MSM is acceptable and feasible, and this model adds a new testing platform to the current testing service system.

Abstract
Obstructive sleep apnea is associated with inflammation and oxidative stress in lung tissues and can lead to metabolic abnormalities. We investigated the effects of angiotensin1-7 [Ang-(1-7)] on lung injury in rats induced by chronic intermittent hypoxia (CIH). We randomly assigned 32 male Sprague-Dawley rats (180-200 g) to normoxia control (NC), CIH-untreated (uCIH), Ang-(1-7)-treated normoxia control (N-A), and Ang-(1-7)-treated CIH (CIH-A) groups. Oxidative stress biomarkers were measured in lung tissues, and expression of NADPH oxidase 4 (Nox4) and Nox subunits (p22phox, and p47phox) was determined by Western blot and reverse transcription-polymerase chain reaction. Pulmonary pathological changes were more evident in the uCIH group than in the other groups. Enzyme-linked immunosorbent assays and immunohistochemical staining showed that inflammatory factor concentrations in serum and lung tissues in the uCIH group were significantly higher than those in the NC and N-A groups. Expression of inflammatory factors was significantly higher in the CIH-A group than in the NC and N-A groups, but was lower than in the uCIH group (P<0.01). Oxidative stress was markedly higher in the uCIH group than in the NC and N-A groups. Expression of Nox4 and its subunits was also increased in the uCIH group. These changes were attenuated upon Ang-(1-7) treatment. In summary, treatment with Ang-(1-7) reversed signs of CIH-induced lung injury via inhibition of inflammation and oxidative stress.

Abstract
OBJECTIVES Despite a recent increase in the HIV/AIDS epidemic among young people in China, youth-specific HIV data are limited. METHODS In total, 56 621 individuals with HIV/AIDS, aged 15-24 years, registered in the Case Reporting System of China between 2005 and 2012 and having complete spatial information were included in the present analysis. Spatial autocorrelation (general and local) and space-time scanning were performed using the ArcGIS 10.2 and SaTScan 9.3 software, respectively. RESULTS During 2005-2012, the number of reported HIV/AIDS cases and the proportion of HIV cases increased while the proportion of AIDS cases decreased. Sexual contact became the predominant route of transmission in later years. Spatial analysis showed marked geographical variations in HIV infection among young people throughout China during 2005-2012. The number of new hotspots increased over time. They were mainly localized to southeastern coastal areas, southwestern frontier provinces or autonomous regions (of Guangxi, Yunnan and Sichuan) and Beijing municipality. Later these hotspots disappeared and new hotspots were found in the northeast of the country. Significant clusters of HIV-positive cases were identified in three different time periods, which indicated high HIV transmission among young Chinese people in the recent past. The risk of HIV infection was highest in the first cluster (2009-2012; this cluster was the largest in size) covering the provinces of Guizhou and Yunnan, the Chongqing municipality, Guangxi, and the province of Sichuan. The second cluster (2010-2012) was mostly located in Shanghai, South Jiangsu, Zhejiang and South Anhui, while the third cluster (2010-2012) was located in Beijing and Tianjin. CONCLUSIONS Target-specific comprehensive behavioural interventions are urgently needed to contain the HIV epidemic among young people.

Abstract
OBJECTIVE To conduct an economic evaluation of the use of trans-obturator tape (TOT) compared with tension-free vaginal tape (TVT) in the surgical treatment of stress urinary incontinence in women. DESIGN Cost-utility and cost-effectiveness analyses from a public-payer perspective, conducted alongside a randomised clinical trial. SETTING Health services provided in Alberta, Canada. SAMPLE A total of 195 women participated in the randomised clinical trial, followed to 5 years postsurgery. METHODS Comparisons were undertaken between study groups for cost and two health-outcome measures. Multiple imputation was used to estimate the 14% of missing data. Bootstrapping was used to account for sampling uncertainty. Sensitivity analyses were based on complete case analyses and the removal of a TVT patient with extreme health service cost. MAIN OUTCOME MEASURES The 15D instrument was used to calculate quality-adjusted life-years (QALYs) for the primary analysis. Absence of serious adverse events was also analysed. Costs were based on inpatient and outpatient hospital use data and practitioner fee-for-service claims data. RESULTS The TOT group had a nonsignificant average saving of $2368 (95% CI -$7166 to $2548) and incremental gain of 0.04 QALYs (95% CI -0.06 to 0.14) compared with TVT. TOT was dominant in over 71% of bootstrap replications and cost-effective over a wide range of willingness-to-pay. Cost-effectiveness analysis using the absence of an serious adverse events provided similar results. CONCLUSION The results suggest that TOT is cost-effective compared with TVT in the treatment of stress urinary incontinence. TWEETABLE ABSTRACT The results of a 5-year cost-effectiveness analysis suggest that trans-obturator tape is cost-effective compared with tension-free vaginal tape in the treatment of stress urinary incontinence.

Abstract
OBJECTIVE To analyze subtypes of the clinical presentation of moderate-to-severe obstructive sleep apnea syndrome (OSAS) by cluster analysis and to explore its significance. METHODS A retrospective analysis was performed on the data of adult moderate-to-severe OSAS patients, which were diagnosed in Respiratory Department, Renmin Hospital of Wuhan University from October 2012 to October 2015. Fifteen kinds of clinical presentations were included in the cluster analysis, and analysis of characteristic of each cluster was then performed after category. RESULTS Patients were classified as three distinct clusters. They were identified as "daytime sleepiness group" , "night insomnia group" and "minimally symptomatic group" , consisting of 450 cases (44.64%), 351 cases (34.82%) and 207 cases (20.54%) of the entire cohort. Members in daytime sleepiness group had the highest probability of daytime sleepiness, tiredness, irritableness and the highest Epworth Sleeping Scale score[329 cases (73.11%), 280 cases (62.22%), 223 cases (49.56%) and (13.50±4.93) points], members in night insomnia group had the highest probability of complaining of insomnia, nocturia, night sweats, apnea and awakening[177 cases (50.43%), 157 cases (44.73%), 130 cases (37.04%), 296 cases (84.33%), 182 cases (51.85%)], the probability of having typical symptoms above was the lowest in minimally symptomatic group, but these patients were more likely to have related comorbidities: hypertension, coronary heart disease, arrhythmia, chronic obstructive pulmonary disease and gastroesophageal reflux disease[118 cases (57.00%), 41 cases (19.81%), 44 cases (21.26%), 34 cases (16.43%), 38 cases (18.36%)]; all above results were significantly higher than the other two groups (P<0.012 5). The rate of diabetes in minimally symptomatic group[28 cases (13.53%)]was also higher but the difference was not statistical significance. CONCLUSION Cluster analysis contributes to classify multiple clinical presentations of OSAS patients, which has important significance for recognizing disease heterogeneity and early diagnosis.

Abstract
Angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) reduces proteinuria and the rate of renal function deterioration in diabetic nephropathy and other glomerular diseases, but its role in quiescent lupus nephritis has not been established. We conducted a retrospective study to investigate the effects of ACEI/ARB on proteinuria and renal function in patients with persistent proteinuria (>1 g/day) despite resolution of acute lupus nephritis following immunosuppressive treatment. Fourteen out of 92 patients were included. The duration of treatment with ACEI/ARB was 52.1 ± 35.7 months. The levels of proteinuria, serum albumin, serum creatinine, systolic and diastolic blood pressure were 1.10 to 6.90 g/day, 35.8 ± 3.6 g/L, 102.54 ± 34.48 μmol/L, 137.6 ± 10.9 and 81.9 ± 9.2 mmHg at baseline. Proteinuria and serum albumin showed significant sustained improvements after 6 and 24 months of treatment. Comparison of slopes for serial proteinuria, albumin and reciprocal of serum creatinine before and after treatment showed significant improvements in six (43%), eight (57%) and two patients, respectively. At last follow-up proteinuria remained significantly lower (0.36 g/day, P = 0.043) and albumin higher (41.3 ± 2.2 g/L, P = 0.023). Eleven (78.6%) patients had proteinuria improved by >50%, and five had insignificant proteinuria at last follow-up. Systolic blood pressure was significantly reduced from 6 months onwards, but this did not correlate with proteinuria reduction. Diastolic blood pressure, serum creatinine, creatinine clearance, anti-dsDNA, C3 and haemoglobin were not altered. We conclude that ACEI/ARB effectively reduces proteinuria and improves serum albumin in patients with persistent proteinuria despite quiescent lupus nephritis.

Abstract
To understand the potential protection of heat shock protein 90 (HSP90) induced by aspirin against heat stress damage in chicken myocardial cells, enzyme activities related to stress damage, cytopathological changes, the expression and distribution of HSP90, and HSP90 mRNA levels in the myocardial cells exposed to heat stress (42°C) for different durations with or without aspirin administration (1 mg/ml, 2 h prior) in vitro were investigated. Significant increase of enzyme levels in the supernatant of heat-stressed myocardial cells and cellular lesions characterised by acute degeneration, karyopyknosis and karyorrhexis were observed, compared to non-treated cells. However, the lesions of cells treated with aspirin were milder, characterised by earlier recovery of enzyme levels to the control levels and no obvious heat stress-related cellular necrosis. Stronger positive signals in the cytoplasm and longer retention of HSP90 signal in nuclei were observed in aspirin-treated myocardial cells than those of only heat-stressed cells. HSP90 level in the aspirin-treated myocardial cells was 11.1-fold higher than that in non-treated cells, and remained at a high level at the early stage of heat stress, whereas it was just 4.1-fold higher in only heat-stressed cells and returned rapidly to a low level. Overexpression of HSP90 mRNA in aspirin-treated cells was observed throughout the experiment, whereas HSP90 mRNA decreased significantly only in heat-stressed cells. The early higher HSP90 expression induced by aspirin during heat stress was accompanied by decreased heat stress damage, suggesting that aspirin might play an important role in preventing myocardial cells from heat stress damage in vitro.

Abstract
Increasing evidence observed in clinical phenotypes show that abrupt breathing disorders during sleep may play an important role in the pathogenesis of sudden unexplained nocturnal death syndrome (SUNDS). The reported Brugada syndrome causing mutation R1512W in cardiac sodium channel α subunit encoded gene SCN5A, without obvious loss of function of cardiac sodium channel in previous in vitro study, was identified as the first genetic cause of Chinese SUNDS by us. The R1512W carrier was a 38-year-old male SUNDS victim who died suddenly after tachypnea in nocturnal sleep without any structural heart disease. To test our hypothesis that slight acidosis conditions may contribute to the significant loss of function of mutant cardiac sodium channels underlying SUNDS, the biophysical characterization of SCN5A mutation R1512W was performed under both extracellular and intracellular slight acidosis at pH 7.0. The cDNA of R1512W was created using site-directed mutagenesis methods in the pcDNA3 plasmid vector. The wild type (WT) or mutant cardiac sodium channel R1512W was transiently transfected into HEK293 cells. Macroscopic voltage-gated sodium current (INa) was measured 24 hours after transfection with the whole-cell patch clamp method at room temperature in the HEK293 cells. Under the baseline conditions at pH 7.4, R1512W (-175 ± 15 pA/pF) showed about 30% of reduction in peak INa compared to WT (-254 ± 23 pA/pF, P < 0.05). Under the acidosis condition at pH 7.0, R1512W (-130 ± 17 pA/pF) significantly decreased the peak INa by nearly 50% compared to WT (-243 ± 23 pA/pF, P < 0.005). Compared to baseline condition at pH 7.4, the acidosis at pH 7.0 did not affect the peak INa in WT (P > 0.05) but decreased peak INa in R1512W (P < 0.05). This initial functional study for SCN5A mutation in the Chinese SUNDS victim revealed that the acidosis aggravated the loss of function of mutant channel R1512W and suggested that nocturnal sleep disorders-associated slight acidosis may trigger the lethal arrhythmia underlying the sudden death of SUNDS cases in the setting of genetic defect.

Abstract
Introduction There are several classifications for abdominal hernias, and a non-traumatic lateral wall hernia (LAWH) is a rare type. We report the first case of a patient with LAWH infected with the human immunodeficiency virus (HIV). Case History A 53-year-old HIV-infected male presented with an abdominal mass. The patient had a history of treatment with combination antiretroviral therapy. A LAWH was diagnosed based on physical examination and findings of computed tomography. Open mesh repair was undertaken successfully. The patient had no evidence of a recurrent hernia during 11 months of follow-up. Conclusions High intra-abdominal pressure and weak connective tissue can lead to LAWHs. Antiretroviral therapy and lipodystrophy can cause LAWHs in HIV-infected patients.

Abstract
THOC6 is a part of the THO complex, which is involved in coordinating mRNA processing with export. The THO complex interacts with additional components to form the larger TREX complex (transcription export complex). Previously, a homozygous missense mutation in THOC6 in the Hutterite population was reported in association with syndromic intellectual disability. Using exome sequencing, we identified three unrelated patients with bi-allelic mutations in THOC6 associated with intellectual disability and additional clinical features. Two of the patients were compound heterozygous for a stop and a missense mutation, and the third was homozygous for a missense mutation; the missense mutations were predicted to be pathogenic by in silico analysis and modeling. Clinical features of the three newly identified patients and those previously reported are reviewed; intellectual disability is moderate to severe, and malformations are variable including renal and heart defects, cleft palate, microcephaly, and corpus callosum dysgenesis. Facial features are variable and include tall forehead, short upslanting palpebral fissures +/- deep set eyes, and a long nose with overhanging columella. These subtle facial features render the diagnosis difficult to make in isolation with certainty. Our results expand the mutational and clinical spectrum of this rare disease, confirm that THOC6 is an intellectual disability causing gene, while providing insight into the importance of the THO complex in neurodevelopment.

Abstract
BACKGROUND Hydrogen sulfide (H2 S) is endogenously generated from L-cysteine (L-Cys) by the enzymes cystathionine-β-synthase (CBS) and cystathionine-γ-Lyase (CSE). Hydrogen sulfide is also produced from D-cysteine (D-Cys) by D-Amino acid oxidase (DAO). METHODS The H2 S production was measured by the methylene blue assay. The expression of DAO was investigated by Western blotting and immunohistochemistry. The short-circuit current (Isc) was recorded using the Ussing chamber technique. KEY RESULTS The epithelium in rat jejunum possesses DAO, and generates H2 S. D-cysteine, originally used as a negative control for L-Cys, significantly increases the H2 S release, which is inhibited by I2CA, an inhibitor of DAO. In vitro study by Ussing chamber technique reveals that D-Cys decreases the Isc across the epithelium of the rat jejunum and enhances the Na(+) -coupled L-alanine transport.

Small scale green infrastructure design to meet different urban hydrological criteria. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2016; 171:92-100. [PMID: 26831449 DOI: 10.1016/j.jenvman.2016.01.016] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/27/2015] [Revised: 01/05/2016] [Accepted: 01/13/2016] [Indexed: 06/05/2023]
Abstract
As small scale green infrastructures, rain gardens have been widely advocated for urban stormwater management in the contemporary low impact development (LID) era. This paper presents a simple method that consists of hydrological models and the matching plots of nomographs to provide an informative and practical tool for rain garden sizing and hydrological evaluation. The proposed method considers design storms, infiltration rates and the runoff contribution area ratio of the rain garden, allowing users to size a rain garden for a specific site with hydrological reference and predict overflow of the rain garden under different storms. The nomographs provide a visual presentation on the sensitivity of different design parameters. Subsequent application of the proposed method to a case study conducted in a sub-humid region in China showed that, the method accurately predicted the design storms for the existing rain garden, the predicted overflows under large storm events were within 13-50% of the measured volumes. The results suggest that the nomographs approach is a practical tool for quick selection or assessment of design options that incorporate key hydrological parameters of rain gardens or other infiltration type green infrastructure. The graphic approach as displayed by the nomographs allow urban planners to demonstrate the hydrological effect of small scale green infrastructure and gain more support for promoting low impact development.

Clinical experience from Thailand: noninvasive prenatal testing as screening tests for trisomies 21, 18 and 13 in 4736 pregnancies. Prenat Diagn 2016; 36:224-31. [PMID: 26748603 DOI: 10.1002/pd.4775] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2015] [Revised: 12/03/2015] [Accepted: 01/05/2016] [Indexed: 12/25/2022]
Abstract
PURPOSE The purpose of this article is to report the clinical experience and performance of massively parallel sequencing-based noninvasive prenatal testing (NIPT) as a screening method in detecting trisomy 21, 18, and 13 (T21/T18/T13) in a mixed-risk population in Thailand. METHODS In a 30-month period, 121 medical centers in Thailand offered NIPT as clinical screening tests for fetal T21, T18, and T13 in the mixed-risk population. All NIPT-positive cases were recommended to undergo invasive prenatal diagnosis. RESULTS A total of 4736 participants received the NIPT test, including 2840 high-risk pregnancies, either with advanced maternal age or positive serum biochemical tests, and 1889 low-risk pregnancies without conventional indications; 99.9% (4732/4736) of the participants with a median maternal age of 35 years old received reports, and 1.3% (63/4732) were classified as test positive, including 36 T21, 19 T18, and 8 T13; 82.5% (52/63) took prenatal diagnosis, and 11.5% (6/52) false-positive cases were observed. The positive predictive values for the detection of T21, T18, and T13 were 94.4%, 79.0%, and 87.5%, respectively. CONCLUSION With stringent protocol, our prospective large-scale multicenter nationwide study demonstrated that NIPT showed excellent performance as screening tests for the detection of fetal T21, T18, and T13 in mixed-risk pregnancies in Thailand.

Abstract
Sudden cardiac death (SCD) is progressively threatening the lives of young people throughout the world. We conducted a retrospective study of SCD cases identified among sudden death cases based on comprehensive autopsies and pathological examinations in the Center for Medicolegal Expertise of Sun Yat-Sen University to investigate the exact etiological distribution and epidemiological features of SCD. One thousand six hundred fifty-six cases were identified, and SCD accounted for 43.0% of these sudden death cases. The mean age of the SCD cases-where the data of definite ages were accessible-was 38.2 years, and the highest incidence occurred among the 31- to 40-year-old cases (25.6%). The male-to-female ratio among SCD cases was 4.3:1, and this ratio peaked in the 41- to 50-year-old group (7.7:1). The places of death were confirmed in 1411 cases, and predominantly in hospitals (46.3%) and at home (33.8%). SCD occurred throughout the year with a marginally increase in April and May. The major causes of SCD were coronary atherosclerotic disease (CAD, 41.6%), unexplained sudden death (15.1%), and myocarditis (11.8%). Our data indicated that in the age group of younger affected persons (below 35 years old), sudden unexplained death and myocarditis were much more prevalent than CAD. According to anatomical examinations of the CAD-related SCD cases, the proportion of cases with coronary artery stenosis exceeding 75% (grade IV) was 67.2%. Moreover, the percentages of higher grades of coronary atherosclerosis increased with age. Among all branches of the coronary arteries, the left anterior descending branch was the most prone to atherosclerosis; atherosclerosis was present in this branch in 95.4% of the cases with atherosclerosis. Additionally, lesions of multiple branches of the coronary artery were associated with ageing. This is the first study to report the causes of death and basic epidemiological data related to SCD in Southern China.

Abstract
Sudden unexplained nocturnal death syndrome (SUNDS) is a perplexing disorder to both forensic pathologists and clinic physicians. Desmoplakin (DSP) gene was the first desmosomal gene linked to arrhythmogenic right ventricular cardiomyopathy (ARVC) which was associated with sudden death. To identify the genetic variants of the DSP gene in SUNDS in the southern Chinese Han population, we genetically screened the DSP gene in 40 sporadic SUNDS victims, 16 Brugada syndrome (BrS) patients, and 2 early repolarization syndrome (ERS) patients using next generation sequencing (NSG) and direct Sanger sequencing. A total of 10 genetic variants of the DSP gene were detected in 11 cases, comprised of two novel missense mutations (p.I125F and p.D521A) and eight previously reported rare variants. Of eight reported variants, two were previously considered pathogenic (p.Q90R and p.R2639Q), three were predicted in silico to be pathogenic (p.R315C, p.E1357D and p.D2579H), and the rest three were predicted to be benign (p.N1234S, p.R1308Q, and p.T2267S). This is the first report of DSP genetic screening in Chinese SUNDS and Brugada syndrome. Our results imply that DSP mutations contribute to the genetic cause of some SUNDS victims and maybe a new susceptible gene for Brugada syndrome.

Abstract
Small roll angle is hard to be measured directly by commercial interferometer instruments due to their low sensitivities in axial direction. A method for its measurement based on a heterodyne interferometer is presented, which adopts accessories including a half wave plate, a multiple-reflector, and a phase meter to achieve test by detecting phase differences between the measurement and reference arms. Mathematical model reveals the resolution will be improved by increasing pass times through the half wave plate. The theoretical resolution is up to 0.19 in. when the pass times increase to three and the phase meter resolution is 0.01°. The proposed method is proved by the experiment.

Abstract
The aim of the study was to develop a new chewable benazepril hydrochloride(BH) tablet, investigate its physical properties, and evaluate its bioequivalence with the branded formulation (Fortekor). A corrective agent was included in the formula to improve its palatability and convenience for administration to dogs. The tablet remained stable in light, heat, and humidity tests, and its physical properties such as hardness, uniformity of content, and dissolution rate were highly consistent with the technical standards. After single and repeated administrations to eight beagles and single dose to 14 mongrel dogs (0.5 mg/kg p.o.), plasma BH and its active metabolite, benazeprilat (BZ), were detected. There was no significant difference in the major pharmacokinetic parameters (Cmax , Tmax, and AUC₀₋₂₄) between the two formulations. The 90% confidence intervals calculated for the ratios of area under the time-concentration curve (AUC₀₋₂₄) were 92.4-116.3% for BH and 89.9-102.3% for BZ, within the accepted range for bioequivalence of 80-125%. The results showed our new chewable tablet is bioequivalent to the commercial product and suitable for addition to the benazepril product family for the treatment of heart failure in dogs.

Abstract
The activation of cancer-associated fibroblasts (CAFs) is a key event in tumor progression, and alternative extracellular matrix (ECM) proteins derived from CAFs induce ECM remodeling and cancer cell invasion. Here we found that miR-200 s, which are generally downregulated in activated CAFs in breast cancer tissues and in normal fibroblasts (NFs) activated by breast cancer cells, are direct mediators of NF reprogramming into CAFs and of ECM remodeling. NFs with downregulated miR-200 s displayed the traits of activated CAFs, including accelerated migration and invasion. Ectopic expression of miR-200 s in CAFs at least partially restored the phenotypes of NFs. CAF activation may be governed by the targets of miR-200 s, Fli-1 and TCF12, which are responsible for cell development and differentiation; Fli-1 and TCF12 were obviously elevated in CAFs. Furthermore, miR-200 s and their targets influenced collagen contraction by CAFs. The upregulation of fibronectin and lysyl oxidase directly by miR-200 or indirectly through Fli-1 or TCF12 contributed to ECM remodeling, triggering the invasion and metastasis of breast cancer cells both in vitro and vivo. Thus, these data provide important and novel insights into breast CAF activation and ECM remodeling, which trigger tumor cell invasion.

Abstract
Increasing evidence indicates that aberrant neutrophil extracellular trap (NET) formation could contribute to the pathogenesis of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Recent research has provided evidence that a novel type of ANCA autoantibody, anti-lysosomal membrane protein-2 (LAMP-2) antibody, may have a pathogenic role in AAV. We have shown previously that anti-LAMP-2 antibody-stimulated NET formation contains autoantigens and anti-microbial peptides. The current study sought to determine whether LAMP-2, as a novel antigen of ANCA, was present on NETs in AAV patients, the influence of the anti-LAMP-2 antibody on the neutrophil apoptosis rate and the role of autophagy in anti-LAMP-2 antibody-induced NET formation. NET formation was assessed using immunofluorescence microscopy, scanning electron microscopy or live cell imaging. The neutrophil apoptosis rate was analysed using fluorescence activated cell sorting (FACS). Autophagy was detected using LC3B accumulation and transmission electron microscopy. The results showed that enhanced NET formation, which contains LAMP-2, was observed in kidney biopsies and neutrophils from AAV patients. The apoptosis rate decreased significantly in human neutrophils stimulated with anti-LAMP-2 antibody, and this effect was attenuated by the inhibitors of autophagy 3-methyladenine (3MA) and 2-morpholin-4-yl-8-phenylchromen-4-one (LY294002). The anti-LAMP-2 antibody-stimulated NET formation was unaffected by benzyloxycarbonyl-Val- Ala-Asp (OMe)-fluoromethylketone (zVAD-fmk) and necrostatin-1 (Nec-1), which are inhibitors of apoptosis and necrosis, respectively, but was inhibited by 3MA and LY294002. Moreover, the proportion of LC3BI that was converted to LC3BII increased significantly (P=0.0057), and massive vacuolizations that exhibited characteristics typical of autophagy were detected in neutrophils stimulated with anti-LAMP-2 antibody. Our results provide further evidence that autophagy is involved in ANCA-induced NET formation in human neutrophils.

Abstract
Platinum-induced myelosuppression severely impedes successful chemotherapy in non-small-cell lung cancer (NSCLC) patients. Hence, it is clinically important to identify the patients who are at high risk for severe toxicity to certain chemotherapy. We first carried out a genome-wide scan of 906 703 single-nucleotide polymorphisms (SNPs) to identify genetic variants associated with platinum-induced myelosuppression risk in 333 NSCLC patients with chemotherapy. Then, we replicated 24 SNPs that had P<1 × 10(-4) in another independent cohort of 876 NSCLC patients. With P<0.05 as the criterion of statistical significance, we found that rs13014982 at 2q24.3 and rs9909179 at 17p12 exhibited consistently significant associations with myelosuppression risk in both the genome-wide association studies (GWAS) scan and the replication stage (rs13014982: odds ratio (OR)=0.55, 95% confidence intervals (CIs): 0.41-0.74, P=7.29 × 10(-5) for GWAS scan and OR=0.77, 95% CI: 0.65-0.93, P=0.006 for replication stage; rs9909179: OR=0.51, 95% CI: 0.37-0.70, P=4.60 × 10(-5) for GWAS scan and OR=0.82, 95% CI: 0.68-0.99, P=0.040 for replication stage; both in additive model). In combined samples of genome-wide scan and replication samples, the minor alleles of rs13014982 and rs9909179 remained significant associations with the decreased risk of myelosuppression (rs13014982: OR=0.71, 95% CI: 0.61-0.83, P =1.36 × 10(-5); rs9909179: OR=0.76, 95% CI: 0.65-0.89, P=0.001). Rs13014982 at 2q24.3 and rs9909179 at 17p12 might be independent susceptibility markers for platinum-induced myelosuppression risk in NSCLC patients.
