Abstract
Ferroptosis represents a non-apoptotic form of programmed cell death characterized by iron-dependent lipid peroxidation. This cell death modality not only facilitates the direct elimination of cancer cells, but also enhances their susceptibility to other pharmacological anti-cancer agents. The burgeoning interest in ferroptosis has been driven by a growing body of evidence that underscores the efficiency and minimal toxicity of ferroptosis inducers. Traditional inducers, such as erastin and RSL3 have shown substantial promise in clinical applications due to their potent therapeutic effects. Their significant potential of these inducers has spurred the development of a variety of small molecule ferroptosis inducers. These novel inducers boast an enhanced structural variety, improved metabolic stability, the capability to initiate ferroptosis without triggering apoptosis, making them well-suited for in vivo use. Despite these advancements, challenges still remain, particularly concerning the drug delivery, tumor specificity, and circulation duration of these small molecules in vivo. Addressing these challenges, contemporary research has pivoted towards innovative delivery systems tailored for ferroptosis inducers to facilitate precise, targeted, and synegestic therapeutic delivery. This review scrutinizes the latest progress in small molecule ferroptosis inducers and nano drug delivery systems geared towards ferroptosis sensitization. Furthermore, it delineated the prospective therapeutic advantages and the existing hurdles in the development of ferroptosis inducers for malignant tumor treatment.

Abstract
Objective: To summarize the imaging presentations of the fallopian canal cerebrospinal fluid leaking (FCCFL). Methods: The high resolution CT (HRCT)and MRI materials of 4 patients (4 ears) with FCCFL confirmed by surgery between August 2016 to November 2023 were retrospectively analyzed. Among these, there were 2 males and 2 females, their ages ranged from 6 to 69 years. Results: All of the FCCFL were unilateral, including 2 on the left and 2 on the right.Clinically, the patients with FCCFL suffered from clear nasal fluid flow, ear tightness, and hearing loss. On CT, all of the affected ears were depicted markedly dilatation of the proximal portion of fallopian canal(FC), the labyrinthine segment and geniculate fossa were involved in 4 cases, and involvement of tympanic segment in 1 case at the same time. The geniculate fossa in the affected side were significantly enlarged, protruding upwards into the tympanic cavity, with one case simultaneously involving the cochlea. On MRI, the hyposignal on T1WI and hypersignal on T2WI or water sequence like cerebrospinal fluid (CSF) were shown in the enlargement FC, without diffusion restriction, and non-enhancing with administration Gadolinium contrast.CSF-like signal effusion was shown in all of the affected tympanum, of which, the CSF-like signal effusion was demonstrated in the area along the superficial petrosal nerve, the right pterygopalatine fossa and the parapharyngeal space. The adjacent intracranial meninges were presented thickening in 3 cases. Conclusion: The imaging appearances of FCCFL present some characteristics:on HRCT, the proximal portions of the affected FC depicts markedly enlargement,especially the geniculate fossa.While they present CSF-like signal, no diffusion restriction, and no enhancement administration, Gadolinium contrast on MRI, accompanying the CSF-like signal effusion in the affected tympanum.

Abstract
Water environmental management (WEM) has a significant influence on the global ecological balance. As an institutional innovation, the River Chief System (RCS) in China has achieved a positive short-term impact on addressing water environmental problems. However, its effects are limited in rural China. As a type of public good, the rural WEM demands the active participation not only of government but also of farmers. Based on the social cognitive and social network theory, this study empirically investigates how rural social networks promote farmers' participation in WEM. Using the survey of 860 farmers in the Yellow and Yangtze River Basin, we employ the double-hurdle model (D-H-M) to craft the primary assessment. The results show that the social network embeddedness facilitates farmers' participation in WEM directly. Collective efficacy plays a full mediation role in the relationship between social network embeddedness and farmers' participation. Moreover, the perceived role of village leaders affects the relationship between social networks and farmers' participation. Our research enriches the application of social network theory in the rural social context and offers an innovative approach to solving farmers' participation problems in WEM.

Abstract
Effisayil 1 was a multicentre, randomized, double-blind, placebo-controlled study of the anti-interleukin (IL)-36 receptor monoclonal antibody, spesolimab, in patients presenting with a generalized pustular psoriasis (GPP) flare. Previously published data from this study revealed that within 1 week, rapid pustular and skin clearance were observed in patients receiving spesolimab versus placebo. In this pre-specified subgroup analysis, the efficacy of spesolimab was evaluated according to patient demographic and clinical characteristics at baseline in patients receiving spesolimab (n = 35) or placebo (n = 18) on Day 1. Efficacy was by assessed by achievement of primary endpoint (Generalized Pustular Psoriasis Physician Global Assessment [GPPGA] pustulation subscore of 0 at Week 1) and key secondary endpoint (GPPGA total score of 0 or 1 at Week 1). Safety was assessed at Week 1. Spesolimab was found to be efficacious and had a consistent and favourable safety profile in patients presenting with a GPP flare, regardless of patient demographics and clinical characteristics at baseline.

Abstract
BACKGROUND AND PURPOSE The detection rate of premortem MR imaging endolymphatic hydrops is lower than that of postmortem endolymphatic hydrops in Ménière disease, indicating that current MR imaging techniques may underestimate endolymphatic hydrops. Therefore, we prospectively investigated whether a novel high-resolution MR imaging technique, the 3D zoomed imaging technique with parallel transmission real inversion-recovery (3D-ZOOMit real IR), would improve the detection of endolymphatic hydrops compared with conventional 3D TSE inversion-recovery with real reconstruction. MATERIALS AND METHODS Fifty patients with definite unilateral Ménière disease were enrolled and underwent 3D-ZOOMit real IR and 3D TSE inversion-recovery with real reconstruction 6 hours after IV gadolinium injection. The endo- and perilymph spaces were scored separately. The contrast-to-noise ratio, SNR, and signal intensity ratio of the 2 sequences were respectively calculated and compared. The presence of endolymphatic hydrops was evaluated. RESULTS The endolymphatic space in the cochlea and vestibule was better visualized with 3D-ZOOMit real IR than with conventional 3D TSE inversion-recovery with real reconstruction (P < .001). There were differences between the 2 sequences in the evaluation of no cochlear hydrops and cochlear hydrops (both, P < .017). All contrast-to-noise ratio, SNR, and signal intensity ratio values of 3D-ZOOMit real IR images were statistically higher than those of conventional 3D TSE inversion-recovery with real reconstruction (all, P < .001). CONCLUSIONS The 3D-ZOOMit real IR sequences are superior to conventional 3D TSE inversion-recovery with real reconstruction sequences in visualizing the endolymphatic space, detecting endolymphatic hydrops, and discovering contrast permeability.

Abstract
Objective: Reflux esophagitis (RE) may be negatively correlated with Helicobacter pylori (H. pylori) infection, but the conclusion and relevant mechanism is still controversial. This study proposed to explore the correlation between RE and H. pylori infection based on natural population. Methods: From July 2013 to December 2014, 3 940 residents aged 40-69 years were recruited in Linqu County of Shandong Province and Hua County of Henan Province by the whole sampling method. All the subjects underwent gastroscopy, and gastric mucosa biopsy specimens were collected for pathological diagnosis and Warthin-Starry (WS) staining to identify H. pylori infection. Venous blood samples of some subjects were collected for H. pylori immunoglobulin G (H. pylori-IgG) detection. Also, demographic and sociological data were collected. Chi-square test and logistic regression were used to analyze the correlation between RE and H. pylori infection. Results: A total of 359 cases of RE were detected. Excluding RE and other upper gastrointestinal organic diseases, 3 382 cases were considered as controls. Chi-square test showed that WS staining positive rate in RE group was significantly lower than that in control group (P=0.023), but there was no significant difference in the positive rate of H. pylori-IgG between the two groups (P=0.281). There were significant differences between RE group and control group in gender composition, age, body mass index (BMI), smoking, alcohol consumption, education level and mucosal active inflammation. Multivariate regression analysis showed that RE was negatively correlated with gastric mucosa active inflammation [OR=0.754 (95%CI 0.600-0.949), P=0.016], and positively correlated with male [OR=4.231 (95%CI 3.263-5.486), P<0.001], age ≥60 years, BMI≥24 kg/m2 [OR=1.540 (95%CI 1.220-1.945), P<0.001]. Compared to those aged 40-49 years and 50-59 years, the odds ratio (OR) of RE in these aged ≥60 years were 1.566 (95%CI 1.144-2.143, P=0.005) and 1.405 (95%CI 1.093-1.805, P=0.008). Conclusion: RE is more closely related to H. pylori present infection. Multivariate analysis showed that RE is negatively correlated with active inflammation of gastric mucosa caused by H. pylori infection, and positively correlated with male, overweight and aged ≥60 years.

Abstract
Objective: To investigate the clinical features and prognosis in patients with idiopathic sudden sensorineural hearing loss (ISSNHL) with blood-labyrinth barrier breakdown (BLB-B). Methods: Clinical data of patients with unilateral ISSNHL hospitalized from December 2017 to December 2018 were retrospectively analyzed. According to the results of 3D-FLAIR MRI and enhanced MRI scanning, these patients were divided into two groups, i.e., normal and abnormal inner ear groups. The patients in abnormal inner ear group were further divided into two subgroups: BLB-B and BLB-B with exudation. The differences and correlations among the groups in clinical characteristics, in terms of gender, age, deafness side, basic diseases, dizziness/vertigo, vestibular function, hearing loss degree, as well as classification of hearing curve, and prognosis were analyzed by statistical software SPSS 23.0. Results: Data were collected from 150 cases, in which 68 were male and 82 were female, aged (46.2±14.6) years, including 67 cases with normal inner ears and 83 cases with abnormal inner ears (13 cases with BLB-B; 70 cases with BLB-B and exudation). The dizziness/vertigo incidence, side ratio, hearing loss degree, classification of hearing curve, vestibular dysfunction (vestibular double temperature test, HIT and VAT) and therapeutic effect were different between normal and abnormal inner ear groups (P<0.05). The dizziness/vertigo incidence, side ratio, hearing loss degree, classification of hearing curve, vestibular dysfunction (vestibular double temperature test, o/cVEMP, HIT and VAT) and therapeutic effect were different among normal inner ear, BLB-B and BLB-B with exudation groups (P<0.05). Pairwise comparison between groups revealed that vestibular dysfunction (vestibular double temperature test, o/cVEMP, HIT and VAT) and therapeutic effect were different between normal inner ear and BLB-B groups (P<0.05); The dizziness/vertigo incidence, side ratio, hearing loss degree, classification of hearing curve, vestibular dysfunction (vestibular double temperature test, o/cVEMP, HIT and VAT) and therapeutic effect were different between normal inner ear and BLB-B with exudation groups (P<0.05). There was no significant different between BLB-B and BLB-B with exudation groups. Conclusion: BLB-B displayed by 3D-FLAIR MRI manifestation in ISSNHL patients indicates more serious cochlear and vestibular dysfunction, and worse therapeutic effect.

Abstract
Objective: The characteristics of 3D-FLAIR MRI images of the inner ear of patients with vestibular neuritis were preliminarily studied to explore the possible pathogenesis of vestibular neuritis, and the correlation analysis was conducted in combination with vestibular function to provide a basis for accurate diagnosis of vestibular neuritis. Methods: A total of 36 patients with vestibular neuritis (VN) from December 2019 to October 2020 were collected from the Vertigo Department of Shandong Provincial ENT Hospital, Cheeloo College of Medicine, Shandong University. There were 36 cases (18 females, 18 males) with unilateral acute vestibular neuritis, 17 cases of left ear and 19 cases of right ear. According to the results of 3D-FLAIR MRI in the inner ears, the patients were divided into the enhanced group and the non-enhanced group (the health side served as the normal control group). The results of vestibular function examination in the two groups were compared. SPSS19.0 software was used for statistical processing to analyze the relationship between the vestibular function and the characteristics of 3D-FLAIR imaging in the inner ears. Results: Abnormal enhancement of 3D-FLAIR was found in 31 cases (86.1%) of the 36 cases, including 14 cases of both vestibular nerve and vestibular terminal organ enhancement, eight cases of superior vestibular nerve enhancement alone, seven cases of vestibular terminal organ enhancement alone, and two cases of cochlear enhancement alone. Observation of abnormal reinforcement of vestibular nerve showed: twenty-one cases of superior vestibular nerve reinforcement, one case of superior and inferior vestibular nerve reinforcement. No abnormalities were found in 3D-FLAIR of inner ear in 5 cases. According to the analysis of vestibular function results, there were 19 cases (52.8%) with total vestibular involvement, sixteen cases (44.4%) with superior vestibular involvement alone, and one case (2.8%) with inferior vestibular involvement alone. Comparison of vestibular function between the five cases (non-enhancement group) and the 31 cases (enhanced group) in the 3D-FLAIR group of the inner ears showed that the CP values of caloric tests in the enhanced group were higher (60.81±3.49 vs 34.12±7.37), with statistically significant difference (t=-2.898, P<0.01). Conclusion: In patients with vestibular neuritis, 3D-FLAIR MRI scan of the inner ear provides visual imaging evidence for clinical practice, considering that the lesion site of vestibular neuritis is not only in the vestibular nerve, but also in the vestibular end organ. Patients with 3D-FLAIR enhanced in the inner ear may have more significant vestibular function damage.

Abstract
Objective: To compare the differences of hip offset and rotation center reconstruction between robot-assisted and manual total hip arthroplasty (THA). Methods: Patients underwent robot-assisted and manual THA from May to September of 2020 in the First Affiliated Hospital of Chongqing Medical University were enrolled in this study. The patients included 27 patients (28 hips) in robot-assisted THA (rTHA) group and 29 patients (31 hips) in manual THA (mTHA) group. In rTHA group, there were 16 males and 11 females, with a mean age of (59±13) years. In mTHA group, there were 18 males and 11 females, with a mean age of (63±14) years. Basic information, including gender, age, body mass index (BMI), diagnosis and functional scoring etc, were recorded. In rTHA group, Mako robot system was used for preoperative planning, intraoperative real-time location and navigation. In mTHA group, traditional preoperative template design and surgical procedure were carried out. Operation time and functional scoring were compared postoperatively. Femoral offset, acetabular offset, global offset, rotation center changes in vertical and horizontal directions were measured on pelvis X-ray and analyzed. The correlation between intraoperative feedback of global offset change in robot system and postoperative measured global offset were analyzed. Results: Operation time in rTHA group was (80±10) min, which was statistically longer than that in mTHA group ((58±18) min, P<0.001). With 6 months' follow-up, the Harris scoring in rTHA group was 94.9±2.8, which was statistically higher than that in mTHA group (93.1±2.8, P=0.017), however there was no statistic difference in WOMAC scoring between rTHA and mTHA group (7.0±3.8 vs 7.1±2.4, P=0.840). Absolute global offset change within 5 mm, 5-10 mm and lager than 10 mm were 71.4%(20/28), 28.6%(8/28) and 0 in rTHA group, which were 45.2%(14/31), 29.0%(9/31) and 25.8%(8/31) in mTHA group (all P<0.05). A positive relation was found between intraoperative feedback of global offset change in robot system and postoperative measured global offset in rTHA group (r=0.77, P<0.001). It was found that rotation center changes concentrated in outer upper quadrant in both groups, and rotation center change in rTHA group concentrated mainly in the area less than 10 mm, however, rotation center change in mTHA group was more dispersive compared with rTHA group. Conclusion: rTHA may accurately reconstruct hip offset and rotation center, intraoperation feedback of global offset change may be an effective reference.

Abstract
BACKGROUND Screening procedures for early Alzheimer's disease (AD) trials seek to efficiently identify participants who fulfill clinical and biomarker criteria for AD and enrich for those most likely to experience significant clinical progression during the study. Episodic memory performance is often assessed in screening, but the utility of different memory tests for optimizing screening efficiency and/or rates of clinical progression remains uncertain. OBJECTIVES Cross-study comparisons of the effects of inclusion criteria based on performance on the Free and Cued Selective Reminding Test (FCSRT) or the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) on screen-failure rates for episodic memory and β-amyloid (Aβ) positivity (by CSF or PET) and on subsequent rates of clinical disease progression in randomized participants across three clinical trials in early (prodromal-to-mild) AD. DESIGN Secondary analyses of cross-sectional and longitudinal clinical trial data. SETTING Multi-center international clinical trials. PARTICIPANTS Individuals with prodromal-to-mild AD screened and/or randomized in clinical trials for crenezumab (CREAD, CREAD2) or semorinemab (Tauriel). Cross-sectional analyses of screening data for episodic memory impairment included participants from CREAD2 (n=2897) and Tauriel (n=887) and for Aβ positivity included participants from CREAD (n=1138), CREAD2 (n=1119), and Tauriel (n=483). Longitudinal analyses of rates of clinical progression included participants from CREAD (n=779), CREAD2 (n=773), and Tauriel (n=331). MEASUREMENTS Cross-sectional analyses examined eligibility rates per cutoffs defined for the FCSRT (CREAD, CREAD2) or RBANS (Tauriel) and per Aβ positivity using CSF and/or PET biomarkers. Longitudinal analyses examined rates of clinical progression on the Clinical Dementia Rating-Sum of Boxes (CDR-SB), the 13-item version of the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog13), and Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale (ADCS-ADL). RESULTS Lower rates of study eligibility per episodic memory criteria were seen with the FCSRT (CREAD2) relative to the RBANS (Tauriel), but similar rates of eligibility per Aβ positivity criteria were seen amongst participants with episodic memory impairment per the cutoffs used on either assessment. Similar rates of clinical decline over 18 months on the CDR-SB, ADAS-Cog13, and ADCS-ADL were observed in study populations enriched using the FCSRT (CREAD, CREAD2) or the RBANS (Tauriel). CONCLUSIONS Cutoffs for episodic memory impairment on the FCSRT used in the CREAD and CREAD2 studies are more stringent than those on the RBANS used in the Tauriel study, resulting in lower rates of eligibility. However, given that study enrichment with either test yields similar rates of Aβ positivity and clinical progression, considerations beyond these factors may drive the decision of which assessment to use for screening in early AD clinical trials.

Abstract
OBJECTIVE This study investigated the impact of smoking on the incidence of insomnia. STUDY DESIGN Systematic review and meta-analysis of cohort studies. METHODS PubMed, EMBASE, Web of Science, Cochrane Library, and OVID were searched through March 2020. Cohort studies reporting the effect of smoking on the incidence of insomnia were included. We quantitatively analyzed the basic framework and study characteristics and then pooled estimate effects with 95% confidence intervals (CIs) of outcomes of each included study using fixed-effects meta-analyses. RESULTS This systematic review included six cohort studies involving 12,445 participants. Quantitatively summarized results suggested that smoking could significantly increase the incidence of insomnia (odds ratio [OR]: 1.07, 95% CI: 1.02, 1.13). Regular smoking was significantly associated with the incidence of insomnia (OR = 1.07, 95% CI: 1.01, 1.13). As for occasional smokers and ex-smokers, the pooled analysis did not indicate a significant association (occasional smoker: OR = 2.09, 95% CI: 0.44, 9.95; ex-smoker; OR = 1.02, 95% CI: 0.67, 1.54). Subgroup analysis by age, gender ratio, and region showed a statistically significant relationship between smoking and the incidence of insomnia in specific groups. CONCLUSIONS Integrated longitudinal observational evidence identified smoking as a significant risk factor of insomnia. Considering the limited amount of available studies, more high-quality and prospective cohort studies of large sample sizes are needed to explore details of this association.

Abstract
AIM To compare and assess T1rho values of the femorotibial cartilage compartments and subregional menisci in patients with hyperuricaemia at 3 T. MATERIALS AND METHODS Thirty-two patients were enrolled in the study and were subdivided into two subgroups: 15 healthy controls (three women, 12 men; mean age = 45.3 ± 10.9 years, age range 25-72 years) and 17 patients with asymptomatic hyperuricaemia (two women, 15 men; mean age = 44.4 ± 12.7 years, age range 26-77 years). All patients were evaluated using 3 T magnetic resonance imaging (MRI) using an eight-channel phased-array knee coil (transmit-receive). Wilcoxon's rank sum test and analysis of covariance (ANCOVA) were conducted to determine whether there were any statistically significant differences in the T1rho values of the femorotibial cartilage compartments and subregional menisci between the two subgroups. RESULTS Lateral tibial cartilage (45.8 ± 2.9 ms) in the healthy subgroup had significantly lower (p<0.05) T1rho values than those of all subcompartments of the femorotibial cartilage in the hyperuricaemia subgroup. The lateral femoral cartilage (LF) in hyperuricaemia (54.6 ± 3.9 ms) subgroup had significantly higher (p<0.05) T1rho values than those of all subcompartments of the femorotibial cartilage except the LF in the healthy subgroup. Significantly higher (p<0.05) T1rho values existed in the LF of the healthy (54.6 ± 4.7 ms) subgroup in comparison with those of all subcompartments of femorotibial cartilage except the LF in hyperuricaemia subgroup. CONCLUSIONS T1rho values in certain compartments of the femorotibial cartilage in patients with hyperuricaemia are elevated compared to those in healthy patients presumably due to reduced proteoglycan content, to which particular attention should be paid when diagnosing and treating the patients with hyperuricaemia in a clinical setting.

Abstract
BACKGROUND People with intellectual disability face a number of barriers to participation in physical activity. This paper aimed to determine rates of sport and physical activity participation in an Australian sample of adults with intellectual disability, compared with rates of participation in the general Australian population. A secondary aim was to investigate factors that may contribute to participation of adults with intellectual disability. METHOD Participants were part of the Australian Child to Adult Development (ACAD) study, consisting of a community sample with intellectual disability (n = 305), groups of adults with autism (n = 94), Down syndrome (n = 64), fragile X syndrome (n = 52), Williams syndrome (n = 45), and Prader-Willi syndrome (n = 30). Participation in sport/physical activity was reported over the past 3 months. Rates of participation were reported for adults with intellectual disability and compared with rates in a general Australian population sample. The relationship between participation in physical activity and age, degree of intellectual disability, physical mobility, living situation, socio-economic disadvantage, and behaviour and emotional problems were also conducted. RESULTS Participants in the ACAD community sample with intellectual disability participated in sport/physical activity at lower rates than the general Australian population (42% compared with 71%). Having no physical mobility impairment was significantly associated with higher rates of participation. Those with Down syndrome participated in sport/physical activity at higher rates than the community sample with intellectual disability, while no difference in sport/physical activity participation was observed in the groups with autism or other syndromes. CONCLUSION Australian adults with intellectual disability participate in sport and physical activity at lower rates than the general population. Having a physical mobility impairment was associated with lower rates of participation. However, people living in supported accommodation were more likely to participate than those in other living situations. Having Down syndrome was associated with a higher participation rate than the community sample.

Abstract
Objective: To analyze the epidemiological characteristics of human brucellosis (HB), evolution and origin feature of Brucella strains in Tongliao city, Inner Mongolia Autonomous Region during 2004-2018, and to provide evidence for strategy development against the disease. Methods: Data from the reports on HB in Tongliao during 2004-2018 were extracted from the China Information System for Disease Control and Prevention before being analyzed with software Excel 2016. Epidemiologic feature was described, using the number of cases, constituent ratio and related rates. Conventional biotypes methods were used for identification of species/biovars strains while species of six Brucella strains were further verified by AMOS-PCR. Cluster analyze on six Brucella strains were performed with Bio-Numerics 5.0 software and for examining and revealing the genetic characteristics of the related strains. Results: During 2004-2018, a total of 16 704 HB cases were reported, with the incidence rate as 35.41/100 000. The incidence rates appeared as 110.51/100 000 in Jarud Banner and 67.84/100 000 in Kulun flag, which were both higher than the other areas. Most of the cases were reported in the 40-54 year olds, which accounted for 48.75% (8 143/16 704). The number of HB in farmers appeared as 14 873, which counted for 89.04% (14 873/16 704) of all the cases. Male to female ratio of incidence was 2.40∶1. Most of the reported cases appeared between March to May, which accounted for 56.30% (9 405/16 704). Peak of the disease was seen in April. Using the conventional identification method, results showed that the available six strains all belonged to B. melitensis, including three of them as B. melitensis bv.1 and others three strains as B. melitensis bv. 3. Results from the amplified AMOS-PCR showed that all the strains were B. melitensis. The six strains clustered in two MLVA-11 genotypes (111 and 116) and all belonged to the Eastern Mediterranean lineage. Based on the MLVA-16 cluster analysis, results suggested that strains from this study were having close genetic relationship with B. melitensis strains that were from Jilin and Heilongjiang provinces. Conclusions: Human brucellosis identified in Tongliao area was with greater risk in spreading the disease to the vicinity. Our findings indicated that the programs on detection and control of the disease should be strengthened.

Abstract
Objective: To investigate the expression of IL-18 in peripheral blood of HBsAg positive parturients in intrauterine transmission of HBV. Methods: A case-control study was conducted in 282 HBsAg positive parturients and 43 health parturients (control group) in Northwest Women and Children Hospital of Shaanxi Province. Enzyme-linked immunosorbent assay (ELISA) was used to detect five serological makers of hepatitis B, real time PCR was used to detect HBV DNA, and flow liquid chip method was used to detect IL-18 levels in peripheral blood of parturients and newborns. Results: The incidence of dominant HBV infection (DBI), occult HBV infection (OBI) and intrauterine transmission of HBV were 8.42% (24/285), 40.00% (114/285) and 48.42% (138/285), respectively. The level of IL-18 in peripheral blood of HBsAg-negative parturients were significantly lower than those of HBsAg-positive parturients (P=0.001), non-HBV intrauterine transmission (NBIT) group (P=0.001) and OBI group (P<0.001). The level of IL-18 in HBeAg negative group was significantly lower than that in HBeAg positive group (P=0.023). When HBV DNA load was ≥10(3) copies/ml, the level of IL-18 was significantly higher than that in HBsAg-negative group (P<0.01). With the increase of HBV DNA load in maternal blood, the level of IL-18 increased (P=0.024). When HBV DNA load was 10(3)-10(6) copies/ml, the level of IL-18 in DBI group was significantly lower than that in NBIT group (P=0.022), and increased with the increase of HBV DNA load in maternal blood (P=0.016). With the increased severity of intrauterine transmission of HBV, the level of IL-18 in non-hepatitis B vaccine group decreased significantly (P=0.044). The level of IL-18 in non-hepatitis B vaccine group and immunoglobulin injection group was significantly higher than that in NBIT group (P<0.05). Multivariate analysis showed that the linear relationship between maternal HBeAg status and maternal IL-18 levels had statistical significance (P=0.01). Conclusions: IL-18 is a higher level balance regulator of Th1/Th2 immune network. Monitoring the level of IL-18 in HBsAg-positive parturients can be used not only for predicting the probability of DBI and OBI, but also as an intervention mean, especially for those who are HBeAg-positive and had HBV DNA load ≥10(3) copies/ml, to improve maternal cellular immune function, which is conducive to interrupting intrauterine transmission and providing a theoretical basis for the prevention and control of HBV intrauterine transmission.

Abstract
Objective: To investigate the influence of IFN-γ and IL-12 levels in prenatal peripheral blood of HBsAg-positive parturients on intrauterine transmission of hepatitis B virus (HBV). Methods: A case-control study was conducted in 282 HBsAg positive parturients and 43 health parturients (control group) in Northwest Women and Children Hospital of Shaanxi Province. Enzyme-linked immunosorbent assay (ELISA) was used to detect five serological makers of hepatitis B in peripheral blood of parturients. HBV DNA was detected by real-time fluorescence quantitative PCR. Detection of cytokines IFN-γ and IL-12 levels were conducted with liquid chip-based flow cytometry method. The serum levels of five serological markers of hepatitis B and HBV DNA in 285 newborns were detected within 24 hours after birth. Results: The incidence of intrauterine dominant infection (DBI), occult infection (OBI) and intrauterine transmission of HBV in HBsAg positive parturients were 7.37% (21/285), 40.70% (116/285) and 48.07% (137/285), respectively. The level of IFN-γ in peripheral blood of HBsAg-negative parturients was significantly lower than those of HBsAg-positive parturients (t=-2.55, P=0.011), NBIT group (t=-2.54, P=0.012) and OBI group (t=-2.33, P=0.021). In HBV DNA load of 10(3)-10(6) copies/ml group, the levels of IFN-γ in the DBI group were significantly lower than those in OBI group and NBIT group (P<0.01). The level of IFN-γ in maternal peripheral blood decreased significantly with the increased severity of intrauterine transmission of HBV (χ(2)=6.40, P=0.041). In the antiviral treatment group, the level of IL-12 in maternal peripheral blood decreased significantly with the increased severity of intrauterine transmission of HBV (χ(2)=8.90, P=0.012). Multivariate analysis showed that there was a significant linear relationship between maternal IFN-γ level and maternal age, placenta previa and hepatitis B vaccine injection (P<0.05). The linear relationship between the level of maternal IL-12 and the mode of rupture and hepatitis B vaccine injection had statistical significance (P<0.05). Conclusions: HBV can stimulate the expression of IFN-γ and inhibit the secretion of IL-12 in pregnant and lying-in women, but the expression of IFN-γ in HBsAg-positive parturients showed intra-group differentiation, and the maternal level of IFN-γ will decrease in HBeAg-positive and high-HBV DNA loadstatus. Increasing the levels of IFN-γ and IL-12 in HBsAg-positive parturients is beneficial to block intrauterine transmission of HBV, especially DBI.

Abstract
Bombyx mori nucleopolyhedrovirus (BmNPV) is one of the primary pathogens that causes severe economic losses to sericulture. Comparative transcriptomics analysis has been widely applied to explore the antiviral mechanism in resistant strains. Here, to identify genes involved in BmNPV infection, we identified differentially expressed genes (DEGs) and performed weighted gene co-expression network analysis (WGCNA) between two Bombyx mori strains: strain 871 (susceptible to BmNPV infection) and the near-isogenic strain 871C (resistant to BmNPV). Our results showed that 400 genes were associated with resistance in strain 871C, and 76 genes were related to susceptibility in strain 871. In addition, the correlation analysis of DEGs and WGCNA showed that 40 genes related to resistance were highly expressed in the resistant strain. Among them, gene BGIBMGA004291 was the most noticeable. We further identified the effect of gene BGIBMGA004291, which encoded a multiprotein bridge factor 2 (MBF2) family member (MBF2-10), on viral infection in cells. Our data suggested that MBF2-10 inhibited viral infection. Taken together, this study showed specific module trait correlations related to viral infection in strains 871 and 871C, and we identified a resistance-related gene. These findings suggested promising candidate genes with antiviral activity, aiding in the analysis of the antiviral molecular mechanisms in resistant strains.

Abstract
Abstract
Background:
The treatment landscape for women with HR+/HER2- advanced and metastatic breast cancer (A/MBC) is changing as new agents are being combined with more established treatments to achieve greater efficacy in combating resistant and unresponsive disease. The present study is designed to describe patient characteristics, treatment patterns, and clinical outcomes in a cohort of women with HR+/HER2- A/MBC treated with palbociclib plus aromatase inhibitor (P+AI) or palbociclib plus fulvestrant (P+FV) in the US community oncology setting.
Methods:
Retrospective medical record data from adult women diagnosed with HR+/HER2- A/MBC who initiated P+AI or P+FV for treatment of A/MBC on or after February 3, 2015 were collected from the Vector Oncology Data Warehouse, a network comprised of 10 community oncology practices across the US. Descriptive analyses were performed on patient characteristics, treatment patterns, and clinical outcomes. Time to event outcomes (progression-free rate (PFR) and survival rate (SR)) at 12 (PFR-12, SR-12) and 24 (PFR-24, SR-24) months for the P+AI combination as first line endocrine therapy and 12 and 18 months for the P+FV combination as treatment following prior endocrine based therapy in either the adjuvant or metastatic setting.
Results:
Among 304 patients who received palbociclib combination therapy, 281 (92.4%) received it per labeled indication. Of the 281 on-label users, the focus of reporting here, 233 (82.9%) received P+AI as their initial endocrine therapy after A/MBC diagnosis; 48 (17.1%) received P+FV after prior endocrine therapy for breast cancer. Patient mean age (SD) was 63.1 (11.4) and 68.2 (10.2) years for patients receiving P+AI and P+FV, respectively. Patients were predominantly white (74.2% for P+AI and 77.1% for P+FV patients).The initial dosing for palbociclib was 125mg/day in 85.4% (n=199) of P+AI and 79.2% (n=38) of P+FV patients. Among patients who received P+AI, PFR-12 was 69.8% and PFR-24 was 46.8% with median follow up time of 10.8 months and 36.8% of progression events. The SR-12 was 89.8% and SR-24 was 71.4%. For patients who received P+FV, PFR-12 was 43.5% and PFR-18 was 39.9% with a median follow up time of 7.6 months and 50.0% of progression events. The SR-12 was 76.3% and SR-18 was 65.0%.
Conclusions:
This study provides real-world assessment of treatment patterns and clinical outcomes of patients with HR+/ HER2- A/MBC who received palbociclib in combination with an AI or a FV in US community oncology settings. These findings demonstrate the benefit of palbociclib combination therapy in a diverse real world population.

Abstract
Abstract
Introduction: The American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) revised the HER2 testing guidelines in breast cancer (BC) which was published in December 2013, practically becoming effective in 2014. Since then, many studies reported a significant increase in HER2 positivity rate in BC. Although HER2 has been routinely evaluated in BC for over a decade, HER2 status was not included in SEER registries until 2010. The aim of this study is to look at the effect of the 2013 ASCO/CAP guidelines on HER2 status in the SEER database that captures approximately 28% of all cancers in the US.
Material and Methods. Using data from 18 SEER cancer registries between the years of 2010-2015 when HER2 status for breast cancers was available, women with invasive BC were identified and their HER2 status and race was recorded. The Chi-square test was used to test the significance between positive proportions before and after the new ASCO/CAP guidelines were effective. Logistic regression was used to test if the changes in positivity rate were the same among different races. All calculations were made after excluding cases with unknown/missing HER2 status.
Results: We identified 376,278 women diagnosed with invasive BC between the years 2010-2015. HER2 positivity before 2014 (2010-2013) was 14.4% compared to 15.6% after 2013 (2014-2015) (p<0.001). HER2 positivity increased in all races after 2013. There was no significant difference in the increase of HER2 positivity between whites and blacks after the new guidelines went into effect. Unknown/missing HER2 status continually decreased over the study period from 7.4% in 2010 to 5.3% in 2015. Overall unknown/missing HER2 was significantly different among races: 6.5% in whites; 7.1% in blacks; and 6.2% in other races (p<0.01).
Conclusion: Revised ASCO/CAP HER2 guidelines significantly increased HER2 positivity rates in SEER registries from 14.4% to 15.6% after implementation started in 2014. HER2 positivity increased in all races after 2013. Unknown/missing HER2 status is significantly different among different races. Blacks have highest unknown/ missing HER2 status in SEER registries.

Abstract
To analyze the correlation of the level of serum heat shock protein 90α (HSP-90α) in healthy and breast cancer patients, studying the evaluation of neoadjuvant efficacy and Clinical value of relapse monitoring.
A total of 102 healthy women were selected, 51 cases of breast benign tumor ,423 cases of female breast cancer all diagnosed by pathology,other system malignancies 62 cases. ALL the serum samples HSP-90αwas detected by double-antibody ELISA. The CEA, CA125,CA15-3 were detected by Roche Cobas ECL analyzer. The ROC curve was used to analyze the effectiveness of serum HSP-90α in the early diagnosis of breast cancer. The dynamic changes of HSP-90αlevel before and after treatment were analyzed by Wilcoxon's rank test. Moreover, we also combine the HSP-90αwith CEA,CA125,CA15-3 to evaluate the clinical value of monitoring the recurrence of breast cancer.
The levels of serum HSP-90α (123.49 ± 105.1ng / ml) in breast cancer patients wes significantly higher than that in healthy controls (40.33 ± 14.18ng / ml), benign breast disease (80.15 ± 103.09ng / ml) and carcinoma in situ (34.7 ± (114.31 ± 146.91ng / ml),the difference was statistically significant (P <0.001). .According to the ROC curve analysis of patients and healthy subjects, the cut-offvalue was set as HSP-90=59.7ng / ml, AUC=0.834, the sensitivity and specificity to diagnosis of breast cancer was 90.3% and 78.6% respectively ,the negative predictive value was 93.88%.The levels of serum HSP-90α was significantly decreased (P <0.05) after tumor resection and the patients who obtain PR from the neoadjuvant chemotherapy. When HSP-90=43.22ng / ml was set as the cut-off value for diagnosing the recurrence of breast cancer, AUC=0.877,the sensitivity and specificity were 95.7% and 74.5% respectively, and the negative predictive value was 96.2%. At the same time, we find that combined HSP-90α with CEA, CA125, CA15-3 can improve the accuracy of recurrence prediction.
Serum HSP-90α has a good clinical diagnostic value in breast cancer and can be used as a recurrence monitoring tool for post-adjuvant treatment patients.

Abstract
Abstract
TP53 is a well-known tumor suppressor gene and mutations in TP53 are the most frequent genomic event in most cancers including breast cancer. Recent studies have shown that the frequency, spectrum, timing, and clinical implications of TP53 mutations varied in different molecular subtypes of breast cancer. For example, the frequency of TP53 mutations is the highest in basal-like subtype and lowest in luminal A tumors. However, the evaluation of TP53 protein expression, as a surrogate for TP53 mutations, in large studies in the context of tumor subtypes is limited. In addition, the etiologic relevance of TP53 expression is yet to be investigated. The goal of this study is to evaluate the association of clinical and breast cancer risk factors with TP53 expression, measured using immunohistochemistry (IHC), in breast cancer molecular subtypes. The analysis included 7,226 women with invasive breast cancer who were diagnosed and treated in a tertiary hospital in Beijing, China. Subtypes were defined as Luminal A: ER+ and PR+, HER2–, and low grade (grades 1 or 2); luminal B/HER2–: ER+ and/or PR+, HER2–, and high grade (grade 3); luminal B/HER2+: ER+ and/or PR+, HER2+ (regardless of grade); HER2-enriched: ER–, PR–, and HER2+; Triple-negative (TN): ER–, PR–, and HER2–. As expected, positive TP53 staining showed the lowest frequency in the luminal A (46%) and highest in the TN (61%) and HER2-enriched (63%) subtypes (P-value <0.001). Overall and particularly in luminal A patients, positive TP53 staining was associated with higher frequencies of aggressive tumor features such as higher grade, larger tumor size, higher proliferative index, and EGFR expression. Compared with TP53– patients, TP53+ patients were more likely to have younger ages at onset and increased parity, but these associations were largely driven by the luminal A subtype [OR (95% CI) vs nulliparity = 2.67 (1.59, 4.51); 2.63 (1.52, 4.55); 3.68 (2.01, 6.72) for 1, 2, and ≥3 children, respectively (P-trend = 0.006)]. Luminal A/TP53+ patients were also more likely to have breastfed [OR (95% CI) ever vs never = 1.38 (1.03, 1.85)] than luminal A/TP53– patients. These findings suggest that TP53 IHC staining might be used to further refine the classification of luminal A breast cancer into subgroups with distinct clinical and etiologic relevance.

Abstract
Objective The increment of CD4+CD25−Foxp3+T cells has been reported in systemic lupus erythematosus (SLE) patients. However, the exact identity of this T cell subset is still unclear. Thus, we analyzed CD4+CD25−Foxp3+T cells and Treg cells (CD4+CD25+Foxp3+ T cells) in a large sample of Chinese SLE patients in different disease states. Methods A total of 280 SLE patients and 38 healthy volunteers were enrolled, which included 21 patients with untreated new-onset lupus (UNOL), 13 patients with drug withdrawal more than 6 months and 246 patients with treatments. Phenotypic and functional analysis of peripheral blood CD4+CD25−Foxp3+ T cells and Treg cells were performed by flow cytometry. The correlation of CD4+CD25−Foxp3+T cells and Treg cells with disease activity, clinical indicators and organ involvement were analyzed. Results CD4+CD25−Foxp3+ T cells and Treg cells were significantly increased in SLE patients and showed significantly positive correlations with disease activity. CD4+CD25−Foxp3+ T cells were significantly increased in patients with skin and hematologic involvement as well as arthritis. Diverse changes between CD4+CD25−Foxp3+ T cells and Treg cells when faced with different medications, especially HCQ and MMF. CD4+CD25−Foxp3+ T cells expressed more IFN-γ and less CTLA-4 than CD4+CD25+Foxp3+ T cells, which were similar to CD4+CD25+Foxp3− T cells, and expressed similar IL-17, ICOS and Helios to CD4+CD25+Foxp3+ T cells. The synthesis capacity of IL-10 of CD4+CD25−Foxp3+ T cells and the expression of GITR on CD4+CD25−Foxp3+ T cells were between CD4+CD25+Foxp3+ and CD4+CD25+Foxp3− T cells. Conclusions Our results indicate that increased CD4+CD25−Foxp3+ T cells in lupus patients, which combined the features of suppression and pro-inflammatory, may serve as a biomarker for disease activity and organ involvement in SLE.

Abstract
Withdrawal of nucleos(t)ide analogues in chronic hepatitis B patients has always been a clinical problem for scholars and patients. Many studies showed that the withdrawal of nucleos(t)ide analogues often leads to a high recurrence rate in clinical practice. The factors such as age, baseline HBV DNA load, time of drug consolidation therapy, and HBsAg level are associated with recurrence after withdrawal of nucleos(t)ide analogues. In addition, there are many studies on safety after withdrawal of nucleos(t)ide analogues and response to retreatment after recurrence. This article reviews the research advances in the aspects mentioned above.

Abstract
Cannabinoid type 1 receptor (CB1R) inhibition tends to be one of the promising strategies for the treatment of obesity and other related metabolic disorders. Although CB1R inhibition may cause adverse psychiatric effects including depression and anxiety, the investigation of the role of peripheral CB1R on weight loss and related metabolic parameters are urgently needed. We first explored the effect of rimonabant, a selective CB1R antagonist/inverse agonist, on some metabolic parameters in high fat-diet (HFD)-induced obesity in mice. Then, real-time PCR and electrophysiology were used to explore the contribution of high voltage-activated Ca2+ channels (HVACCs), especially Cav1.1, on rimonabant's effect in skeletal muscle (SM) in HFD-induced obesity. Five-week HFD feeding caused body weight gain, and decreased glucose/insulin tolerance in mice compared to those in the regular diet group (P<0.05), which was restored by rimonabant treatment compared to the HFD group (P<0.05). Interestingly, HVACCs and Cav1.1 were decreased in soleus muscle cells in the HFD group compared to the control group. Daily treatment with rimonabant for 5 weeks was shown to counter such decrease (P<0.05). Collectively, our findings provided a novel understanding for peripheral CB1R's role in the modulation of body weight and glucose homeostasis and highlight peripheral CB1R as well as Cav1.1 in the SM as potential targets for obesity treatment.

Abstract
AIMS Endoplasmic reticulum (ER) stress exerts myocardial oxidative stress, apoptosis, and contractile anomalies, although the precise interplay between ER stress and apoptosis remains elusive. This study was designed to examine the impact of the cysteine-rich free radical scavenger metallothionein on ER stress-induced myocardial contractile defect and underlying mechanisms. METHODS AND RESULTS Wild-type friendly virus B and transgenic mice with cardiac-specific overexpression of metallothionein were challenged with the ER stress inducer tunicamycin (1 mg/kg, intraperitoneal, 48 h) prior to the assessment of myocardial function, oxidative stress, and apoptosis. Our results revealed that tunicamycin promoted cardiac remodeling (enlarged left ventricular end systolic/diastolic diameters with little changes in left ventricular wall thickness), suppressed fractional shortening and cardiomyocyte contractile function, elevated resting Ca(2+), decreased stimulated Ca(2+) release, prolonged intracellular Ca(2+) clearance, and downregulated sarco(endo)plasmic reticulum Ca(2+)-ATPase levels, the effects of which were negated by metallothionein. Treatment with tunicamycin caused cardiomyocyte mitochondrial injury, as evidenced by decreased mitochondrial membrane potential (∆Ѱm, assessed by JC-1 staining), the effect of which was negated by the antioxidant. Moreover, tunicamycin challenge dramatically facilitated myocardial apoptosis as manifested by increased Bax, caspase 9, and caspase 12 protein levels, as well as elevated caspase 3 activity. Interestingly, metallothionein transgene significantly alleviated tunicamycin-induced myocardial apoptosis. CONCLUSION Taken together, our data favor a beneficial effect of metallothionein against ER stress-induced cardiac dysfunction possibly associated with attenuation of myocardial apoptosis.

Abstract
The timing and mechanisms of protection by hyperbaric oxygenation (HBO) in
hypoxic-ischemic brain damage (HIBD) have only been partially elucidated. We
monitored the effect of HBO on the mitochondrial function of neuronal cells in the
cerebral cortex of neonatal rats after HIBD. Neonatal Sprague-Dawley rats (total of
360 of both genders) were randomly divided into normal control, HIBD, and HIBD+HBO
groups. The HBO treatment began immediately after hypoxia-ischemia (HI) and continued
once a day for 7 consecutive days. Animals were euthanized 0, 2, 4, 6, and 12 h
post-HI to monitor the changes in mitochondrial membrane potential (ΔΨm) occurring
soon after a single dose of HBO treatment, as well as 2, 3, 4, 5, 6, and 7 days
post-HI to study ΔΨm changes after a series of HBO treatments. Fluctuations in ΔΨm
were observed in the ipsilateral cortex in both HIBD and HIBD+HBO groups. Within 2 to
12 h after HI insult, the ΔΨm of the HIBD and HIBD+HBO groups recovered to some
extent. A secondary drop in ΔΨm was observed in both groups during the 1-4 days
post-HI period, but was more severe in the HIBD+HBO group. There was a secondary
recovery of ΔΨm observed in the HIBD+HBO group, but not in the HIBD group, during the
5-7 days period after HI insult. HBO therapy may not lead to improvement of neural
cell mitochondrial function in the cerebral cortex in the early stage post-HI, but
may improve it in the sub-acute stage post-HI.

Abstract
AimsHigh myopia is a common visual disorder in the world. The ZNF644, GRM6, and CTNND2 genes are expressed in the retina. This study aims to investigate the associations of these genes with high myopia in Han Chinese population.MethodsThe case-control association included high myopia cases (n=430) and controls (n=430) recruited from a population-based study, 'Jiangsu Eye Study'. Fourteen single-nucleotide polymorphisms (SNPs) in three genes were genotyped by the TaqMan method using the real-time PCR system.ResultsThree SNPs GRM6-rs11746675, GRM6-rs2067011, and GRM6-rs2645339 were associated with high myopia (odds ratio (OR)=0.74, P=0.003; OR=0.78, P=0.018; and OR=0.78, P=0.023; respectively). The significances of rs2067011 and rs2645339 disappeared after multiple testing corrections. Rs11746675 remained significant after correction for multiple testing. The genetic model analysis found that GRM6-rs11746675 and GRM6-rs2067011 were suggestively associated with high myopia in the recessive model (OR=0.54, P=0.004; OR=0.52, P=0.003; respectively). Haplotype GAT for GRM6 markers rs2067011-rs2645339-rs762724 showed significance (P=0.0239), but such association did not remain significant after multiple testing corrections.ConclusionsOur data suggested that genetic variants in GRM6 are associated with high myopia. The mechanism of GRM6 in the development of high myopia need to be further investigated.

Abstract
Abstract
Epidemiological studies have shown that associations between breast cancer risk and risk factors vary by tumor pathology such as estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status. Mammographic density (MD) is a strong risk factor for breast cancer, but data on the association between MD and breast cancer subtypes have been inconsistent and most studies have been conducted among Western women. The goal of this study was to evaluate the association between MD and breast cancer subtypes in an Asian population where the proportion of dense breast tissue is higher but the overall breast cancer incidence rate is much lower compared with Western countries. Breast cancer cases from a cancer hospital in Beijing, China with MD and ER, PR, and HER2 immunohistochemical (IHC) data were included in this analysis. To reduce subtype misclassification, we excluded cases that were HER2 2+ for IHC but had no FISH data. Tumor subtypes were defined as Luminal A (ER+ or PR+ and HER2-, N=376), Luminal B (ER+ or PR+ and HER2+, N=97), HER2-overexpressing (ER- and PR- and HER2+, N=71), and triple negative (TN, ER- and PR- and HER2-, N=66). MD was assessed on digital mammograms and categorized into four levels using the Breast Imaging Reporting and Data System (BI-RADS) scoring system (a=almost entirely fat, b=scattered fibroglandular densities, c=heterogeneously dense, and d=extremely dense). Because there were few cases with almost entirely fat breasts, we combined MD levels "a" and "b" as our reference group. Polychotomous logistic regression was used to assess the association between MD and breast cancer subtypes with the adjustment of age, menopausal status, parity, age at menarche, and body mass index (BMI) since all these variables showed significant inverse associations with MD (P=0.002 for age at menarche and P<0.0001 for all others). Compared with luminal A cases, cases with HER2-overexpressing tumors were significantly more likely to have extremely dense breasts (Odds ratio [OR], 2.6; 95% confidence interval [CI], 1.2-5.7). Cases with luminal B (OR, 2.1, 95% CI, 1.2-3.9) and TN (OR, 2.9, 95% CI, 1.5-5.8) tumors had significantly higher proportions of heterogeneously dense but not extremely dense tissue compared with luminal A cases. Our data suggest that higher MD is associated with more aggressive tumor subtypes, particularly the HER2-overexpressing subtype among Chinese breast cancer cases. If confirmed in larger studies, these results may provide insight into the higher incidence rates of HER2-overexpressing breast cancer seen among young Asian American and Asian women.

Abstract
Milk fat globule epidermal growth factor 8 (MFG-E8) is an opsonin involved in the
phagocytosis of apoptotic cells. In patients with chronic obstructive pulmonary
disease (COPD), apoptotic cell clearance is defective. However, whether aberrant
MFG-E8 expression is involved in this defect is unknown. In this study, we examined
the expression of MFG-E8 in COPD patients. MFG-E8, interleukin (IL)-1β and
transforming growth factor (TGF)-β levels were measured in the plasma of 96 COPD
patients (93 males, 3 females; age range: 62.12±10.39) and 87 age-matched healthy
controls (85 males, 2 females; age range: 64.81±10.11 years) using an enzyme-linked
immunosorbent assay. Compared with controls, COPD patients had a significantly lower
plasma MFG-E8 levels (P<0.01) and significantly higher plasma TGF-β levels
(P=0.002), whereas there was no difference in plasma IL-1β levels between the two
groups. Moreover, plasma MFG-E8 levels decreased progressively between Global
Initiative for Chronic Obstructive Lung Disease (GOLD) I and GOLD IV stage COPD.
Multiple regression analysis showed that the forced expiratory volume in 1 s
(FEV1 % predicted) and smoking habit were powerful predictors of MFG-E8
in COPD (P<0.01 and P=0.026, respectively). MFG-E8 was positively associated with
the FEV1 % predicted and negatively associated with smoking habit. The
area under the receiver operating characteristic curve was 0.874 (95% confidence
interval: 0.798-0.95; P<0.01). Our findings demonstrated the utility of MFG-E8 as
a marker of disease severity in COPD and that cigarette smoke impaired MFG-E8
expression in these patients.
