Abstract
Breast cancer (BC) is the fourth most prevalent cancer in China. Despite conventional treatment strategies, BC patients often have poor therapeutic outcomes, leading to significant global cancer mortality rates. Chimeric antigen receptor (CAR)-based immunotherapy is a promising and innovative approach for cancer treatment that redirects immune cells to attack tumor cells expressing selected tumor antigens (TAs). T cells, natural killer (NK) cells, and macrophages, key components of the immune system, are used in CAR-based immunotherapies. Although remarkable progress has been made with CAR-T cells in hematologic malignancies, the application of CAR-based immunotherapy to BC has lagged. This is partly due to obstacles such as tumor heterogeneity, which is further associated with the TA and BC subtypes, and the immunosuppressive tumor microenvironment (TME). Several combinatorial approaches, including the use of immune checkpoint inhibitors, oncolytic viruses, and antitumor drugs, have been proposed to overcome these obstacles in BC treatment. Furthermore, several CAR-based immunotherapies for BC have been translated into clinical trials. This review provides an overview of the recent progress in CAR-based immunotherapy for BC treatment, including targeting of TAs, consideration of BC subtypes, assessment of the TME, and exploration of combinatorial therapies. The authors focused on preclinical studies and clinical trials of CAR-T cells, CAR-NK cells, and CAR-macrophages especially conducted in China, followed by an internal comparison and discussion of current limits. In conclusion, this review elucidates China's contribution to CAR-based immunotherapies for BC and provides inspiration for further research. PLAIN LANGUAGE SUMMARY: Despite conventional treatment strategies, breast cancer (BC) patients in China often have poor therapeutic outcomes. Chimeric antigen receptor (CAR)-based immunotherapy, a promising approach, can redirect immune cells to kill tumor cells expressing selected tumor antigens (TAs). However, obstacles such as TA selection, BC subtypes, and immunosuppressive tumor microenvironment still exist. Therefore, various combinatorial approaches have been proposed. This article elucidates several Chinese CAR-based preclinical and clinical studies in BC treatment with comparisons of foreign research, and CAR-immune cells are analyzed, providing inspiration for further research.

Abstract
Both NO and GAs are essential for regulating various physiological processes and stress responses in plants. However, the interaction between these two molecules remains unclear. We investigated the distinct response patterns of Arabidopsis thaliana Col-0 and GA synthesis functional deficiency mutants to NO by measuring root length. To investigate underlying mechanisms, we detected bioactive GA content using UHPLC-ESI-MS/MS, assessed the accumulation of ROS by chemical staining Arabidopsis roots. We also conducted RNA-seq analysis and compared results between Col-0 and ga3ox1, with and without SNP (as NO donor) treatment. Phenotypic results revealed that the inhibitory effect of NO on primary roots of Arabidopsis was primarily mediated by GA3-oxidase, rather than GA20-oxidase or GA2-oxidase. The content of GA3 decreased in Col-0 treated with SNP, whereas this decrease was not observed in ga3ox1. The deficiency of GA3-oxidase alleviated the buildup of H2 O2 in roots when treated with SNP. We identified 222 DEGs. GO annotation of these DEGs revealed that all top 20 GO terms were related to stress responses. Moreover, three DEGs were annotated to GA-related processes (DDF1, DDF2, EXPA1), and seven DEGs were associated with root development (RAV1, RGF2, ERF71, ZAT6, MYB77, XT1, and DTX50). In summary, NO inhibits primary root growth partially by repressing GA3-oxidase catalysed GA3 synthesis in Arabidopsis. ROS, Ca2+ , DDF1, DDF2, EXPA1 and seven root development-related genes may be involved in crosstalk between NO and GAs.

Abstract
PURPOSE/OBJECTIVE(S) Current deep learning-based dose prediction methods can only predict a specific dose distribution. If the predicted dose is inaccurate, no more options can be selected. We proposed a novel dose prediction method named dose band prediction, which outcomes a spectrum of predicted dose distribution for planning and quality assurance (QA). MATERIALS/METHODS Upper-Band and Lower-Band losses were involved in 3D convolution neural networks to establish the Upper-Band Network (UBN) and Lower-Band Network (LBN). Each voxel's ideal dose spectrum (dose band) was defined by the maximum/minimum rational dose predicted by UBN/LBN. 130 NPC cases with Tomotherapy (dataset 1), 49 cervix cases with IMRT (dataset 2) and 43 cervix cases with VMAT (dataset 3) were enrolled to establish and evaluate our dose band prediction method. RESULTS The dose band prediction method can successfully predict a spectrum of doses. Upper-Band/Lower-Band presents maximum/minimum rational dose; Middle-Line presents the average of Upper-Band and Lower-Band. The clinical implement dose was used as the reference dose. We evaluated the maximum interval between the reference and Upper-Band/Middle-Line/Lower-Band doses, and the percentage dose difference was used as the evaluation method. The differences in PTV for Upper-Band, Middle-Line and Lower-Band in dataset 1 were within 2.47%, 0.54%, and 2.8%; in dataset 2, they were within 0.37%, 1.15%, and 2.69%; in dataset 3, they were within 0.96%, 0.35%, and 1.66%. The mean difference of OARs for the Upper-Band, Middle-Line and Lower-Band in dataset 1 were within 8.13%, 4.97%, and 8.19%; in dataset 2, they were within 8.8%, 4.48%, and 5.52%; in dataset 3, they were within 4.01%, 3.13%, and 5.79% (shown in Table 1). CONCLUSION Dose Band prediction achieved high-accuracy dose prediction by the Middle-Line. More importantly, the Upper-Band/Lower-Band provided a spectrum of possible rational doses. Our Dose Band prediction method is based on a specific loss function, so it can easily be applied in various network and patient cases. Dose Band prediction towards a more robust plan QA and planning assistance. Table 1. The maximum interval of doses (percentage dose difference, %).

Abstract
The tumor microenvironment (TME) is a highly intricate milieu, comprising a multitude of components, including immune cells and stromal cells, that exert a profound influence on tumor initiation and progression. Within the TME, angiogenesis is predominantly orchestrated by endothelial cells (ECs), which foster the proliferation and metastasis of malignant cells. The interplay between tumor and immune cells with ECs is complex and can either bolster or hinder the immune system. Thus, a comprehensive understanding of the intricate crosstalk between ECs and immune cells is essential to advance the development of immunotherapeutic interventions. Despite recent progress, the underlying molecular mechanisms that govern the interplay between ECs and immune cells remain elusive. Nevertheless, the immunomodulatory function of ECs has emerged as a pivotal determinant of the immune response. In light of this, the study of the relationship between ECs and immune checkpoints has garnered considerable attention in the field of immunotherapy. By targeting specific molecular pathways and signaling molecules associated with ECs in the TME, novel immunotherapeutic strategies may be devised to enhance the efficacy of current treatments. In this vein, we sought to elucidate the relationship between ECs, immune cells, and immune checkpoints in the TME, with the ultimate goal of identifying novel therapeutic targets and charting new avenues for immunotherapy.

Abstract
Objective: To analyze the vaginal microecological status of vaginitis population and non-vaginitis population of gynecological female outpatients. Methods: A total of 30 265 women who visited the gynecological outpatient clinic of Beijing Obstetrics and Gynecology Hospital from December 2018 to December 2020 completed vaginal microecological examination. After removing the follow-up patients, 23 181 women were divided into group with symptoms and signs of vaginitis (6 697 cases) and group without symptoms and signs of vaginitis (16 484 cases), according to whether the women with symptoms and signs of vaginitis or not. And the vaginal microecological status of the two groups was compared and analyzed. Results: (1) The total detection rate of vaginitis in the initial women was 34.87% (8 083/23 181), of which 46.10% (3 087/6 697) in group with symptoms and signs of vaginitis and 30.31% (4 996/16 484) in group without symptoms and signs of vaginitis, nearly 1/3 of the gynecological outpatients without signs and symptoms of vaginitis had vaginitis. (2) Among the types of simple vaginitis, vulvovaginal candidiasis (VVC) was the most frequent in group with symptoms and signs of vaginitis (16.01%, 1 072/6 697), followed by aerobic vaginitis (AV; 12.83%, 859/6 697), with significant differences compared with group without symptoms and signs of vaginitis (all P<0.001). There were no statistical differences between the two groups of bacterial vaginosis (BV) and trichomonal vaginitis (TV), indicating that BV and TV were more likely to be neglected (all P>0.05). (3) The proportion of various combinations of vaginitis among 2 632 cases of mixed vaginitis were, in descending order: BV+AV, VVC+AV, BV+AV+VVC, AV+TV, AV+TV+BV, BV+VVC. (4) Microecological analysis of 15 098 cases diagnosed with non-vaginitis had normal flora (including those with normal flora and those with normal flora but decreased function) in 14 013 cases (92.81%, 14 013/15 098), abnormal flora in 429 cases (2.84%, 429/15 098) and the BV intermediate in 656 cases (4.34%, 656/15 098); this indicated that the vast majority of the microecological tests were normal in the vaginal microbiota of those without vaginitis. Conclusions: Microecological examination could diagnose multiple pathogenic infections at once, and is especially important as a guide for the definitive diagnosis of mixed vaginitis and vaginitis with atypical clinical symptoms. Vaginal infections such as BV and TV that are easily overlooked should be concerned.

Abstract
BACKGROUND Probiotics may be an effective alternative to traditional drug therapy for constipation in the elderly. OBJECTIVE To assess the efficacy and safety of probiotics in managing constipation among the elderly. METHODS Eight databases were queried for randomized controlled trials (RCTs) investigating probiotics' efficacy in addressing constipation among the elderly until January 2023. The meta-analysis was conducted employing R software version 4.2.2. The Cochrane risk of bias tool was utilized to evaluate the risk of bias, and the GRADE approach was employed to assess the credibility of the evidence concerning the efficacy of probiotics in treating constipation in older individuals. RESULTS A total of six RCTs involving 444 patients were included. Two studies were rated as low risk of bias. The meta-analysis findings revealed that probiotics, when compared to a placebo, led to an increase in stool frequency (MD = 1.02,95% CI [0.21, 2.07], p<0.05, very low quality), the probiotic group exhibited a notable impact on ameliorating symptoms associated with constipation (OR = 11.28, 95%CI [7.21, 17.64], p < 0.05, very low quality), no significant disparities were observed in terms of efforts to evacuate, manual maneuvers, and the incidence of adverse events (p>0.05). CONCLUSION The available evidence indicates a degree of uncertainty, ranging from low-to-very low, suggesting the efficacy of probiotics in augmenting bowel frequency and ameliorating constipation-related symptoms among elderly patients with constipation. Nevertheless, given the quality of the studies included, it is advisable to conduct further well-designed investigations with substantial sample sizes to substantiate the findings of this study.

Abstract
OBJECTIVE To explore the influence of nutritional status on 90-day functional outcomes of stroke patients with acute large vessel occlusion in the anterior circulation after endovascular treatment (EVT). METHODS We retrospectively analyzed the baseline, laboratory, surgical and 90-day follow-up data of patients with stroke resulting from acute large vessel occlusion in the anterior circulation, who underwent emergency endovascular treatment in our hospital from July, 2015 to December, 2020. A favorable outcome was defined as a modified Rankin scale score ≤2 at 90 days. Univariate and multivariate regression analyses were performed to explore the relationship between nutritional status and 90-day functional outcomes of the patients. RESULTS A total of 459 patients (mean age of 68.29±11.21 years, including 260 males) were enrolled in this study. According to their prognostic nutritional index (PNI), the patients were divided into normal nutrition group (392 cases, 85.4%), moderate malnutrition group (44 cases, 9.6%), and severe malnutrition group (23 cases, 5.0%). Univariate analysis showed that the patients with good clinical outcomes had a lower proportion of malnutrition with a younger age, a lower rate of diabetes, lower baseline blood pressure, lower baseline NIHSS score, higher baseline ASPECT score, and higher rates of good collateral circulation and complete vascular recanalization. Multivariate analysis showed that in addition to age, diabetes, baseline systolic blood pressure, successful recanalization, baseline ASPECT score, baseline NIHSS score and collateral circulation, a greater PNI was a protective factor for a good 90-day outcome of patients after EVT (moderate vs severe: OR=0.245, 95% CI: 0.066-0.908, P=0.035; normal vs severe: OR=0.185, 95% CI: 0.059-0.581, P=0.004). CONCLUSION Nutritional status an important factor affecting the 90-day outcomes after EVT of stroke patients with acute large vessel occlusion in the anterior circulation.

Abstract
Checkpoint with FHA and RING finger domains (CHFR) is a G2 phase/mitosis checkpoint. Several studies have reported that CHFR is downregulated in multiple cancer types and serves a tumor suppressor role. However, the biological function of CHFR in breast cancer (BRCA), particularly regarding metastasis, are yet to be elucidated. In the present study, it was revealed that CHFR is upregulated in BRCA compared with normal tissues, according to The Cancer Genome Atlas database. In addition, subgroup analysis of BRCA revealed that CHFR was upregulated in both human epidermal growth factor receptor 2‑positive and triple‑negative BRCA. Meanwhile, patients with high expression levels of CHFR exhibited poorer overall survival rates. Furthermore, the present data revealed that the overexpression of CHFR in SKBR3 cells resulted in enhanced cell migration and invasiveness, and also significantly upregulated mesenchymal markers, such as N‑cadherin, vimentin, transcription factor Slug and tight junction protein claudin‑1. Furthermore, knockdown of CHFR in MDA‑MB‑231 cells significantly inhibited cell migration and invasiveness, and also downregulated mesenchymal markers, such as N‑cadherin, vimentin and tight junction protein claudin‑1. In conclusion, the current results indicated that CHFR expression was associated with cell metastasis in BRCA by mediating epithelial‑to‑mesenchymal transition.

Abstract
Pollen has various effects on human health and the environment. To understand phenomena behind atmospheric pollen transport and hence improve pollen forecasts, vertically resolved optical properties and geometrical characteristics of the pollen distribution need to be studied. Lidar measurements and especially the particle depolarization ratio have been found to be an excellent tool to track pollen grains. In this study we present first results of atmospheric pollen characterization based on a 11 days period of birch and spruce pollination events.

Abstract
Objective: To evaluate risk factors for visual field (VF) loss progression in primary open-angle glaucoma patients. Methods: A prospective nested case-control study. Patients were collected from the Wenzhou glaucoma progression study in the Eye Hospital of Wenzhou Medical University during March 2014 and April 2018. In this study, the eyes were divided into a progression group and a non-progression group using the glaucoma progression analysis methods to analyze the risk factors for glaucomatous VF loss progression. Axial length (AL) and central corneal thickness (CCT) were measured using the Lenstar LS900. The baseline, fluctuation (standard deviation), mean, maximum, minimum and range of intraocular pressure (IOP) during the follow-up period were determined based on IOP measured at each follow-up. The IOP measurements were included from the baseline to the last visit (for the non-progression group), or to the visit at which VF loss progression was determined (for the progression group). The independent sample t-test, Mann-Whitney U inspection and Cox proportional hazards models were used for statistical analysis. Results: A total of 140 patients (140 eyes) were enrolled, including 67 males and 73 females. There were 19.3% of the eyes (27 of 140 eyes) showing VF loss progression. The median time to the endpoint for progression was 24.0 (16.0, 40.0) months. The AL in the progression group and non-progression group were 23.58 (23.05, 24.24) mm and 23.91 (23.10, 24.91) mm (P=0.111). The CCT in the two groups were 531.0 (512.0, 565.0) μm and 535.0 (518.5, 552.0) μm, respectively (P=0.897). The baseline age in the progression group and non-progression group was 71.0 (68.0, 74.0) years and 68.0 (58.0, 72.0) years, respectively (Z=-2.872, P=0.004). The slope of visual field index in the two groups was -3.50 (-7.10, -1.80)%/year and 0.40 (-0.60, 1.40)%/year, respectively (Z=-6.823, P<0.01). The mean IOP during the follow-up was (16.2±2.7) mmHg (1 mmHg=0.133 kPa) in the progression group and (15.1±2.4) mmHg in the non-progression group (t=-2.215, P=0.028). The IOP fluctuation in the progression group and non-progression group was (2.6±1.3) mmHg and (2.0±0.7) mmHg, respectively (t=-2.175, P=0.038). In the multivariate model, older baseline age (HR=1.080; 95%CI:1.019-1.143), higher baseline IOP (HR=1.120; 95%CI:1.016-1.236), higher mean IOP (HR=1.145; 95%CI:1.001-1.309) and higher IOP fluctuation (HR=1.750; 95%CI:1.193-2.566) were all significantly predictive risk factors for glaucomatous VF loss progression. Longer AL (HR=0.725; 95%CI:0.532-0.988) was a protective factor against VF loss progression. However, CCT was found to be not associated with VF loss progression. Conclusion: Baseline age, baseline IOP, mean IOP, IOP fluctuation and shorter AL are found to be risk factors for glaucomatous VF loss progression among eyes with primary open-angle glaucoma in Wenzhou.

Abstract
Blood-based biomarkers, such as carcinoembryonic antigen (CEA), and saliva-based biomarkers, such as mRNA, have emerged as potential liquid biopsies for non-invasive detection of many cancers. However, current tests typically use single type of biomarkers, and their sensitivity and specificity is often unsatisfactory.In this study, we developed a novel biomarker panel that measures both CEA level in blood and GREB1 and FRS2 levels in saliva to achieve high sensitivity and high specificity in detecting Non-Small Cell Lung Cancer (NSCLC).In the discovery phase, we achieved sensitivity of 96.67% and specificity of 93.33% for 30 NSCLC patients and 30 healthy controls. To further evaluate the prediction performance of our biomarker panel, we applied it to an independent set of 15 NSCLC cancer patients and 25 healthy controls. The sensitivity and specificity of our test reached 93.33% and 80.00% respectively.Our study discovered that the combined analysis of CEA and mRNA can be a novel liquid-biopsy technology for non-invasive detection of NSCLC.

Abstract
Objective: To measure in vivo biomechanical properties of pelvic support structures associated with uterosacral ligament suspension (ULS) . Methods: Ten Chinese female cadavers (death within 48 hours) without embalming were carefully dissected to expose the ligament. After dissection, ligaments were sewn according to standard ULS surgical technique. They were stretched at a steady rate to breakage during constant electronic registration of load and displacement. In vivo biomechanical properties were evaluated by a load-displacement curve. Results: Ultimate load of uterosacral ligament, ring around cervix were (37.3±23.5) , (49.3±28.4) N, respectively. The differences between the two groups was not significant (P>0.05) . Ligament stiffness were (1.26±1.22) , (1.45±0.92) N/mm, respectively. There was no significant difference between groups (P>0.05) . Conclusions: The uterosacral ligament, ring around cervix with sufficient strength are not easy to deform. ULS is an effective procedure for treating middle pelvic defects from a biomechanics perspective.

Abstract
BACKGROUND AND PURPOSE Endovascular thrombectomy has been accepted as the standard of care for patients with acute ischemic stroke. Our aim was to investigate the clinical outcomes of patients with mild ischemic stroke with acute proximal large-vessel occlusion after endovascular treatment within 24 hours of symptom onset. MATERIALS AND METHODS Between January 2014 and August 2017, ninety-three Chinese patients with mild ischemic stroke (NIHSS scores, 0-8) and large-vessel occlusion with endovascular treatment were retrospectively enrolled from 7 comprehensive stroke centers. They were divided into 2 groups: ≤6 hours and 6-24 hours from symptom onset to groin puncture. We analyzed their modified Rankin Scale scores at 90 days, symptomatic intracranial hemorrhage at 48 hours, and mortality during 90 days. Multivariable linear regression analysis was used to identify predictors for NIHSS shift after discharge. RESULTS Twenty-nine patients received endovascular treatment within 6-24 hours after symptom onset and had an imaging mismatch based on perfusion CT or diffusion-weighted MR imaging. There were no substantial differences between the 2 groups in 90-day functional independence (P = .54) and the risks of the combination of symptomatic intracranial hemorrhage and death (P = .72). Two significant indicators of NIHSS shift were 48-hour symptomatic intracranial hemorrhage (unstandardized β = 7.28; 95% CI, 3.48-11.1; P < .001) and baseline systolic blood pressure (unstandardized β = 0.08; 95% CI, 0.03-0.14; P = .005). CONCLUSIONS Patients with mild ischemic stroke and large-vessel occlusion in the anterior circulation, an imaging mismatch, and endovascular treatment within 6-24 hours of initial symptoms showed no heterogeneity in the efficacy and safety outcome compared with those treated ≤6 hours from symptom onset.

Abstract
BACKGROUND The Griffiths Mental Development Scales (GMDS) are used in many countries to assess the development of children from birth to 8 years. There is a need for accurate and culturally appropriate developmental assessment tools for Chinese children. Here, we adapted the GMDS for use in Chinese children and compare the developmental trajectories between Chinese and British children. METHODS Children with typical development were recruited from 7 urban cities in China between 2009 and 2013. The Griffiths Mental Development Scales-Chinese (GDS-C) were adapted and used to assess the development of urban Chinese children. Developmental curves were computed for 6 subscales using learning management system methods and compare against the British curves from the Griffiths Mental Development Scales-Extended Revised (GMDS-ER). RESULTS The GDS-C were used to assess the developmental status of 815 Chinese children. Plots of the 1st, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 99th percentiles, and full percentile tables were obtained, which showed similar trends to data from the British GMDS-ER. CONCLUSIONS The Chinese developmental curves obtained from the GDS-C showed similarities and differences to the developmental curves from the British GMDS-ER. The development of urban Chinese children should be assessed with the culturally appropriate GDS-C.

Abstract
We report a strategy to introduce a reactive electrophile into proteins through the conversion of a chemically inert group into a bioreactive group in response to an inducer molecule. This strategy was demonstrated by oxidation-induced and proximity-enhanced protein-protein crosslinking in the presence of a large excess of free nucleophile.

Abstract
BACKGROUND/OBJECTIVES Prenatal growth, which is widely marked by birthweight, may have a pivotal role in affecting the lifelong risk of cardiometabolic disorders; however, comprehensive evaluation of its relations with childhood cardiometabolic risk patterns and the ethnic and gender disparities in national representative populations is still lacking. The aim of this study was to evaluate the associations between birthweight and comprehensive patterns of cardiometabolic risk in a nationally representative sample of children and adolescents. SUBJECTS/METHODS Prospective analyses were performed using data from 28 153 children 0 to 15 years in the National Health and Nutrition Examination Survey from 1999 through 2014. We defined childhood cardiometabolic disorders using standard definitions for obesity, high blood pressure, hyperglycemia and dyslipidemia. RESULTS Five birthweight categories <2.5, 2.5-3.0, 3.0-3.5, 3.5-4.2 and ⩾4.2 kg accounted for 8.2%, 17.9%, 35.7%, 27.9% and 10.4% of the population, respectively. In all children, with increasing birthweight, we observed significantly increasing trends of the risk of general and central obesity (P for trend <0.01) and significantly decreasing trends of the risk of high systolic blood pressure (SBP), high HbA1c and low high-density lipoprotein cholesterol (HDL-C) (P for trend <0.05). The associations were independent of current body mass index (BMI). In addition, we found that the relations of birthweight with high waist circumference in Black children showed U-shape, as well as high SBP in Mexican and Hispanic children. Moreover, we found that the associations of low birthweight with high SBP and low HDL-C appeared to more prominent significant in boys, whereas the inverse association with high HbA1c was more evident in girls. CONCLUSIONS Our data indicate that birthweight is significantly related to childhood cardiometabolic risk, independent of current BMI, and the associations exhibit race and gender-specific patterns.

Abstract
OBJECTIVE This study aimed to examine the association between baseline and changes in dietary quality assessed by the Alternative Healthy Eating Index-2010 (AHEI-2010) and abdominal aortic calcification (AAC) among community-dwelling older adults. DESIGN Population-based longitudinal study. SETTING A subset of the Melbourne Collaborative Cohort Study (MCCS). PARTICIPANTS 262 community-dwelling adults (60% female) aged 53 ± 5 years at baseline. MEASUREMENTS Dietary intake was assessed using validated Food Frequency Questionnaires at baseline (1990-1994) and follow-up (2010-2011). AAC was evaluated by radiography and dual-energy x-ray absorptiometry (DXA) at follow-up. RESULTS Higher baseline AHEI-2010 score was associated with lower AAC severity by radiography [OR (95% CI) for Tertile 3 VS Tertile 1: 0.53 (0.29-0.99)] after adjustment for gender, age, physical activity, smoking, BMI, systolic blood pressure, plasma total cholesterol, calcium and energy intake. The association between AHEI-2010 and AAC severity by DXA was also significant in the multivariate-adjusted model [OR (95% CI) for Tertile 3 VS Tertile 1: 0.38 (0.20-0.70)]. Changes in AHEI-2010 over 18 years were not associated with AAC severity. CONCLUSION Baseline but not the changes in AHEI-2010 was inversely associated with the risk of AAC severity suggesting that a high quality diet might help prevent or delay the progression of AAC in community-dwelling older adults and the benefits might be manifested over the long-term.

Abstract
A new fluorogenic bioorthogonal reaction between styrene (an unstrained alkene) and a tetrazine was developed.
We developed a new fluorogenic bioorthogonal reaction that is based on the inverse electron-demand Diels–Alder reaction between styrene (an unstrained alkene) and a simple tetrazine. The reaction forms a new fluorophore with no literature precedent. We have identified an aminoacyl-tRNA synthetase/tRNA pair for the efficient and site-specific incorporation of a styrene-containing amino acid into proteins in response to amber nonsense codon. Fluorogenic labeling of purified proteins and intact proteins in live cells were demonstrated. The fluorogenicity of the styrene–tetrazine reaction can be potentially applied to the study of protein folding and function under physiological conditions with low background fluorescence interference.

Abstract
Obolodiplosis robiniae is native to North America and is an important introduced insect pest that forms leaf margin roll galls on species of genus Robinia (Fabaceae) in China. It was first detected in China in 2004, but subsequently spread and provoked local outbreaks. An analysis of a 676-bp sequence of the mitochondrial DNA cytochrome oxidase subunit I was conducted in 560 individuals from 28 populations, in order to (1) assess population genetic structuring and (2) explore possible explanations for the rapid spread and invasion success of O. robiniae. Yet, only four haplotypes were identified and the nucleotide diversity was low (π = 0.00005) and among the 560 specimens studied, only ten showed haplotypic variation involving no more than three substitutions. The result showed a low degree of genetic diversity among populations of the successful invasive gall midge, which suggested that the pest experienced a severe genetic bottleneck and a loss of genetic diversity after its introduction. The successful establishment and spread of O. robiniae in China is attributed to the wide distribution of its host plant, thus allowing ample opportunities for gene flow in the pest species, and to the advantageous life history characteristics of O. robiniae.

Abstract
BACKGROUND Our aim was to clarify the correlation between fatigue during the acute stage of stroke with serum glucose and homocysteine (Hcy) levels and functional disability. MATERIALS AND METHODS A case group of 214 patients and a control group of 214 subjects were recruited during the same period. The serum glucose, Hcy, blood lipid and fibrinogen (FIB) levels of patients were determined. Fatigue was assessed using the Fatigue Severity Scale (FSS). Patients with an FSS score ≥4 points were defined as having fatigue. Stroke severity and the level of functional disability were assessed with the National Institutes of Health Stroke Scale (NIHSS) and the Barthel-20 Index (BI-20), respectively. RESULTS The incidence of fatigue in the case group was higher than that in the control group (P < 0.001). Within the case group, the fatigue group showed higher serum levels of glucose and Hcy, and a lower BI-20 score compared to the non-fatigue group (P < 0.001). Age, gender, chronic disease history, the NIHSS score and the serum blood lipid and FIB levels were not significantly different between the two groups. In the fatigue group, the serum glucose and Hcy levels showed a positive effect and the BI-20 score showed a negative effect on the FSS score (P < 0.01). Age, gender, chronic disease history, the NIHSS score and the serum blood lipid and FIB levels did not significantly affect the FSS score. CONCLUSIONS The serum glucose and Hcy levels and functional disability are closely related to fatigue during the acute stage of ischaemic stroke.

Abstract
Acute cholecystitis (AC) is one of the most common surgical diseases. Bacterial infection accounts for 50% to 85% of the disease's onset. Since there is a close relationship between the biliary system and the gut, the aims of this study were to characterize and determine the influence of gut microbiota on AC, to detect the pathogenic microorganism in the biliary system, and to explore the relationship between the gut and bile microbiota of patients with AC. A total of 185 713 high-quality sequence reads were generated from the faecal samples of 15 patients and 13 healthy controls by 16S rRNA gene pyrosequencing. Patients' samples were significantly enriched in Akkermansia, Enterobacter and Escherichia/Shigella group. The healthy controls, however, showed significant enrichment of Clostridiales, Coprococcus, Coprobacillaceae, Paraprevotella, Turicibacter and TM7-3 in their faecal samples. Escherichia coli was the main biliary pathogenic microorganism, among others such as Klebsiella spp., Clostridium perfringens, Citrobacter freundii and Enterobacter cloacae in the bile of the patients. Additionally, the amount of bile endotoxin significantly correlated with the number of Enterobacteriaceae, especially E. coli. Our data indicate that Enterobacteriaceae might play essential role in the pathogenesis and/or progress of AC. This was verified in an in vivo model using a pathogenic E. coli isolated from one of the patients in guinea pigs and observed marked gallbladder inflammation and morphologic changes. This study thus provides insight which could be useful for the prevention, diagnosis and treatment of AC and related diseases by controlling the growth of Enterobacteriaceae to alleviate the infection.

Abstract
Phenotypic variations in α-thalassemia mainly depend on the defective α-globin gene number. Genetic modifiers of the phenotype of Hemoglobin H (HbH) disease were poorly reported, apart from β-thalassemia allele that was identified ameliorating the severity of α-thalassemia. Because erythroid Krüppel-like factor (KLF1) mutations can modulate the red blood phenotype, we evaluated its effect on the α-thalassemia phenotype. Overall, we identified 72 subjects with five different KLF1 heterozygous mutations in 1468 individuals, including 65 out of 432 α-thalassemia carriers with fetal hemoglobin (HbF) levels ≥1%, 0 out of 310 carriers with HbF levels <1% and 7 out of 726 HbH disease patients. We firstly established the link between KLF1 mutations and relatively elevated hemoglobin A2 (HbA2 ) and HbF levels, along with lower mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) values in a group of α-thalassemia carriers. However, we concluded that KLF1 mutations were not significantly linked to HbH disease severity. On the basis of HBA or HBB genotype and gender, clinical severity of patients with HbH disease was correctly predicted in 73.3% cases. It may improve the screening and diagnostic assessment of α-thalassemia.

Abstract
Abstract
Polymer films with patterned microstructure have been widely applied in various industrial areas such as micro reactors, chemical sensors and micro-molded template etc. In this paper, a self-supporting polymer film with regular honeycomb microstructure is fabricated by self-organization via evaporation of polyphenylene oxide (PPO) solution in which carbon disulfide is used as solvent under humid ambience. Apart from investigation of self-organization mechanism of PPO honeycomb including nucleation, growth of water droplets condensed upon liquid supporting substrate, the quantitative relationship between honeycomb microstructure and ambient conditions is built through tremendous self-organization experiments. The controllable formation of honeycomb microstructure with desirable hydrophobicity was achieved by use of built quantitative relationship. Moreover, hydrophobicity mathematical model of self-organized honeycomb thin film was proposed, and its validation was experimentally verified.

Abstract
Glutamate is the major mediator of excitotoxic neuronal death following cerebral ischemia. Under severe ischemic conditions, glutamate transporters can functionally reverse to release glutamate, thereby inducing further neuronal injury. Hypothermia has been shown to protect neurons from brain ischemia. However, the mechanism(s) involved remain unclear. Therefore, the aim of this study was to investigate the mechanism(s) mediating glutamate release during brain ischemia-reperfusion injury under hypothermic conditions. Neuron/astrocyte co-cultures were exposed to oxygen-glucose deprivation (OGD) at various temperatures for 2h, and cell viability was assayed 12h after reoxygenation. PI and MAP-2 staining demonstrated that hypothermia significantly decreased neuronal injury. Furthermore, [(3)H]-glutamate uptake assays showed that hypothermia protected rat primary cortical cultures against OGD reoxygenation-induced injury. Protein levels of the astrocytic glutamate transporter, GLT-1, which is primarily responsible for the clearance of extracellular glutamate, were also found to be reduced in a temperature-dependent manner. In contrast, expression of GLT-1 in astrocyte-enriched cultures was found to significantly increase following the addition of neuron-conditioned medium maintained at 37 °C, and to a lesser extent with neuron-conditioned medium at 33 °C. In conclusion, the neuroprotective effects of hypothermia against brain ischemia-reperfusion injury involve down-regulation of astrocytic GLT-1, which mediates the reverse transport of glutamate. Moreover, this process may be regulated by molecules secreted by stressed neurons.

Abstract
BACKGROUND Studies in Western countries have repeatedly shown that women with a history of childhood sexual abuse (CSA) are at increased risk for developing major depression (MD). Would this relationship be found in China? METHOD Three levels of CSA (non-genital, genital, and intercourse) were assessed by self-report in two groups of Han Chinese women: 1970 clinically ascertained with recurrent MD and 2597 matched controls. Diagnostic and other risk factor information was assessed at personal interview. Odds ratios (ORs) were calculated by logistic regression and regression coefficients by linear or Poisson regression. RESULTS Any form of CSA was significantly associated with recurrent MD [OR 3.26, 95% confidence interval (CI) 1.95-5.45]. This association strengthened with increasing CSA severity: non-genital (OR 2.47, 95% CI 1.17-5.23), genital (OR 2.77, 95% CI 1.32-5.83) and intercourse (OR 13.35, 95% CI 1.83-97.42). The association between any form of CSA and MD remained significant after accounting for parental history of depression, childhood emotional neglect (CEN), childhood physical abuse (CPA) and parent-child relationship. Among the depressed women, those with CSA had an earlier age of onset, longer depressive episodes and an increased risk for generalized anxiety disorder (GAD; OR 1.92, 95% CI 1.39-2.66) and dysthymia (OR 2.16, 95% CI 1.52-3.09). CONCLUSIONS In Chinese women CSA is strongly associated with MD and this association increases with greater severity of CSA. Depressed women with CSA have an earlier age of onset, longer depressive episodes and increased co-morbidity with GAD and dysthymia. Although reporting biases cannot be ruled out, our results are consistent with the hypothesis that, as in Western countries, CSA substantially increases the risk for MD in China.

Abstract
The α-actinin 3 ( ACTN3) gene is absent in 18% of healthy white individuals owing to homozygosity for a premature stop codon polymorphism (rs1815739) and is only expressed in the Z line of fast glycolytic muscle fibres. Previous studies have shown highly significant association between ACTN3 genotype and sprint/power performance, while the nonfunctional allele (577X) was believed to provide an advantage for endurance performance. In this study we tested whether XX genotype was over-represented in Chinese endurance athletes compared to the general population. In a study of 250 Chinese endurance athletes of provincial or national competitive standard and 450 controls, we proved that the ACTN3 XX genotype (21.2 vs. 15.8%; P=0.02) and X allele (51.3 vs. 41.1%; P=0.019) were significantly over-represented in female endurance athletes compared to controls, while no genotype-related differences were observed in male endurance athletes. Besides, the frequency of the ACTN3 XX genotype (28.6%) was the highest in a group of highly elite athletes compared with other groups, which supported the hypothesis that the absence of α-actinin-3 provided some sort of advantage for endurance athletes. Our results indicated that ACTN3 R577X polymorphism was associated with endurance performance in female athletes but not male athletes in China.

Abstract
Chemoresistance is a major cause of treatment failure and poor outcome in neuroblastoma. In this study, we investigated the expression and function of dual-specificity phosphatase 26 (DUSP26), also known as mitogen-activated protein kinase phophatase-8, in human neuroblastoma. We found that DUSP26 was expressed in a majority of neuroblastoma cell lines and tissue specimens. Importantly, we found that DUSP26 promotes the resistance of human neuroblastoma to doxorubicin-induced apoptosis by acting as a p53 phosphatase to downregulate p53 tumor suppressor function in neuroblastoma cells. Inhibiting DUSP26 expression in the IMR-32 neuroblastoma cell line enhanced doxorubicin-induced p53 phosphorylation at Ser20 and Ser37, p21, Puma, Bax expression as well as apoptosis. In contrast, DUSP26 overexpression in the SK-N-SH cell line inhibited doxorubicin-induced p53 phosphorylation at Ser20 and Ser37, p21, Puma, Bax expression and apoptosis. Using in vitro and in vivo assays, we found that DUSP26 binds to p53 and dephosphorylates p53 at Ser20 and Ser37. In this report, we show that DUSP26 functions as a p53 phosphatase, which suppresses downstream p53 activity in response to genotoxic stress. This suggests that inhibition of this phosphatase may increase neuroblastoma chemosensitivity and DUSP26 is a novel therapeutic target for this aggressive pediatric malignancy.
