Abstract
OBJECTIVE To investigate the therapeutic effect of Sanhuang Xiexin Decoction (SXD) on triple-negative breast cancer (TNBC) in mice and its underlying mechanism. METHODS The high-performance liquid chromatography (HPLC) was used to quantitate and qualify SXD. A total of 15 female BALB/c mice were inoculated subcutaneously on the right hypogastrium with 3×105 of 4T1-Luc cells to establish TNBC mouse model. All mice were divided randomly into 3 groups, including phosphate buffered solution (PBS), SXD and doxorubicin (DOX) groups (positive drug). Additionally, tumor growth, pathological changes, serum lipid profiles, expression of Janus kinase 2 (JAK2)-signal transducer and activator of transcription 3 (STAT3) signaling pathway and its key targets including inflammatory factors, cell cycle and epithelial-mesenchymal transition (EMT) markers were investigated. Besides, the biosafety of SXD was also evaluated in mice. RESULTS Rhein, coptisine, berberine hydrochloride and baicalin were all found in SXD, and the concentrations of these 4 components were 0.57, 2.61, 2.93, and 46.04 mg/g, respectively. The mouse experiment showed that SXD could notably suppress the development of tumors and reduce the density of tumor cells (P<0.01). The serum lipid analysis and Oil-Red-O staining both showed the differences, SXD group exhibited higher serum adiponectin and HDL-C levels with lower TC and LDL-C levels compared to the PBS and DOX groups (P<0.05 or P<0.01), respectively. SXD also decreased the levels of phospho-JAK2 (p-JAK2), phospho-STAT3 (p-STAT3) expressions and its downstream factors, including mostly inflammatory cytokine, EMT markers, S phase of tumor cells and vascular endothelial growth factor (VEGF) expression (P<0.05 or P<0.01), respectively. The biosafety assessment of SXD revealed low levels of toxicity in mice. CONCLUSION SXD could inhibit TNBC by suppressing JAK2-STAT3 phosphorylation which may be associated with modulation of lipid metabolism.

Abstract
Objective: To explore whether blood and polyp tissue eosinophil numbers are independent risk factors for poor disease control in patients with nasal polyp. Methods: By using the electronic medical records database and manual evaluation, 183 nasal polyp patients who had undergone endoscopic sinus surgery at least one year prior to the study with complete data of tissue specimens, baseline blood routine test, nasal endoscopy and sinus computed tomography, were identified and recruited to assess disease control based on the criteria of a European Position Paper on Rhinosinusitis and Nasal Polyps 2012 (EPOS 2012). Multiple logistic regression model was used to determine the association between blood and tissue eosinophil numbers and risk of poor disease control by adjusting for demographics and comorbidities. Results: We broke down the cohort into 4 groups according to blood (0.3×109/L) and tissue (10%) eosinophils. The patients without eosinophilic inflammation represented the largest group (41.5%). The group with concordant blood and tissue eosinophilia represented the second largest (31.2%), and the patients with isolated tissue (15.3%) or blood (12.0%) eosinophilia were relatively rare. Multiple logistic regression models found blood eosinophil count and tissue eosinophil percentage were independently associated with increased risk for poor disease control after adjustments for covariates related to poor treatment outcome. Furthermore, subjects with concordant blood and tissue eosinophilia had a higher risk for poor disease control than those with isolated blood or tissue eosinophilia. Conclusion: Concordant blood and tissue eosinophilia relates to a higher likelihood of poor disease control than isolated blood or tissue eosinophilia after adjustment of potential confounders in nasal polyp patients.

Abstract
Long non-coding RNA (lncRNA) KCNQ1 and opposite strand/antisense transcript 1 (KCNQ1OT1) have been validated to be carcinogenic in several cancers. However, the role of KCNQ1OT1 in regulating the malignant biological behavior and radiotherapy resistance of cervical cancer (CC) remains largely unknown. Quantitative real time-polymerase chain reaction (qRT-PCR) was carried out to detect KCNQ1OT1 and miR-491-5p expression in CC tissues and cells. Pyruvate kinase M1/2 (PKM2) expression was detected by Western blot. CC cell proliferation, movement, migration and invasion were monitored by CCK-8, scratch healing and Transwell assay, respectively. The CC cell colony survival was detected by colony formation assay under different doses of radiation. Dual luciferase reporter gene assay, pull-down assay and RIP assay were employed to verify the targeting relationship between KCNQ1OT1, miR-491-5p and PKM2. In this study, KCNQ1OT1 was significantly up-regulated in CC patient cancerous tissues and cell lines, and its high expression was significantly related to tumor volume increase and poor differentiation. KCNQ1OT1 overexpression significantly promoted CC cell proliferation, metastasis and radioresistance. On the contrary, KCNQ1OT1 knockdown compared to the control group inhibited the above biological behavior of CC cells. The underlying mechanism suggested that KCNQ1OT1 promoted progression and radioresistance of CC by modulating the miR-491-5p/PKM2 axis. In conclusion, KCNQ1OT1 enhances CC cell progression through the miR-491-5p/PKM2 axis.

Abstract
Objective: To explore the temporal and spatial characteristics of search volume (SV) of allergic rhinitis (AR) and related search terms on Baidu Index, as well as the correlation between SV from Baidu Index and epidemiology of AR. Methods: SV of AR and related search terms in mainland area of China from January 2012 to December 2016 were extracted from Baidu Index. Firstly, we investigated the temporal and spatial characteristics of SV of AR and related search terms ("pollen allergy" and" dust mite allergy", etc.), and explored the correlation between SV of AR and SV of related search terms. Secondly, the SV of specific search terms in Beijing and Guangzhou were compared with the actual pollen count in Beijing from April to September in 2016 and the monthly outpatient volume of AR patients in the Otorhinolaryngology Hospital, The First Affiliated Hospital of Sun Yat-sen University from 2014 to 2016 respectively to analyze the consistency between SV from Baidu Index and the real-world data. Spearman correlation analysis was used to explore the correlation between different search terms according to the normality and homogeneity of variance of the data. P<0.05 was considered statistically significant. Results: SV of AR showed repetitively seasonal pattern, with the first peak in May and the second peak from August to September. SV of AR in northeast China, north China and northwest China were correlated with both SV of "pollen allergy" and "dust mite allergy" (r value was 0.533, 0.638, 0.609, 0.791, 0.517, 0.682, respectively, all P<0.05). In east China, central China, south China and southwest China, SV of AR showed significant correlation only with SV of "dust mite allergy" (r value was 0.897, 0.884, 0.799, 0.937, respectively, all P<0.05), but not with SV of "pollen allergy" (r value was 0.110, 0.171, 0.020, 0.265, respectively, all P>0.05). The correlation between pollen count and the SV of AR on the day and SV of "pollen allergy" on the next day was the highest (r value was 0.692 and 0.713, respectively, all P<0.05). The SV of AR was correlated with the monthly outpatient volume of AR patients one month and two months later (r value was 0.523 and 0.503, respectively, all P<0.05). Conclusion: The SV of AR and related search terms show different trends in different times and regions which are consistent with the AR epidemiological survey, and significantly correlate with pollen count and AR outpatient volume.

Abstract
Objective: To study the value of olfactory cleft scores through computed tomography (CT) in predicting the oral glucocorticoids (GC) sensitivity in chronic rhinosinusitis with nasal polyps. Methods: Fourty-seven consecutive patients with CRSwNP from the Fifth Affiliated Hospital of Sun Yat-sen University between January and March of 2018 were recruited in this prospective, single-blinded study. There were 28 males and 19 females, with age ranging from 17 to 66 years old. After a course of oral prednisone (30 mg/d for 14 d), these patients were subsequently classified into objectively GC-sensitive and -insensitive subgroup according to the change in nasal polyp size score, or subjectively GC-sensitive and -insensitive subgroup according to the change in total nasal symptom score. The following parameters were compared between GC-sensitive and -insensitve subgroups: Lund-Mackay scores, olfactory cleft scores, and blood eosinophil counts and ratio. T test and χ(2) test were used. Multivariate Logistic regression analysis was used for factor prediction and receiver operating characteristic (ROC) curve was used to analyze the predictive ability of those factors. Results: There were 53.2% (25/47) and 61.7% (29/47) of patients objectively and subjectively sensitive to GC therapy, respectively. All data conformed to normal distribution. The olfactory cleft score and the blood eosinophil counts and ratio in objectively GC-sensitive subgroup were significantly higher than those in objectively GC-insensitive subgroup (3.6±1.0 vs 2.2±1.4, (404.4±200.3)/μl vs (209.5±233.1)/μl, (5.25±2.59)% vs (3.17±3.46)%, t value was 3.98, 3.08, respectively, χ(2)=2.35, all P<0.05). The cleft score, the blood eosinophil counts and ratio also showed the same trend in subjectively GC-sensitive and -insensitive subgroup (3.6±1.0 vs 1.9±1.3, (401.4±213.6)/μl vs (171.1±200.2)/μl, (5.39±2.76)% vs (2.48±2.99)%, t value was 5.05, 3.68, respectively, χ(2)=3.40, all P<0.05). Multivariate Logistic regression revealed that olfactory cleft score was an independent risk factor for objective or subjective GC-sensitivity (OR=2.882, 95%CI: 1.301-6.384; OR=2.508, 95%CI: 1.248-5.039). The olfactory cleft score exhibited comparable accuracy with the blood eosinophil ratio as predictor of objective and subjective GC-sensitivity (Area under curve of olfactory cleft score was 0.775, 0.829, respectively). An olfactory cleft score of 3.5 could act as a reliable indicator for predicting the clinical response to GC therapy in CRSwNP. Conclusion: Olfactory cleft score through CT scan has the potential value in predicting GC-sensitivity in CRSwNP patients.

Abstract
Objective: To investigate the expression of 11β-hydroxysteroid dehydrogenase (11β-HSD) in polyps of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and its correlation with glucocorticoid sensitivity. Methods: The prospective study method was applied. Forty-three adult CRSwNP patients from Otorhinolaryngology Hospital, First Affiliated Hospital of Sun Yat-sen University between April 2016 and June 2017 were enrolled in this study. There were 19 males and 24 females with the age of (37.44±7.42) years old. The endoscopic scores by nasal Polyps Grading System before and after one-week prednisone treatment (0.5 mg/(kg·d)) were evaluated. The response of glucocorticoid by the total endoscopic scores was estimated. According to the patient's reduced nasal polyp endoscopic score, patients were devided into nasal polyps insensitive to glucocorticoids treatment group (insensitive group) and nasal polyp sensitive to glucocorticoids treatment group (sensitive group). The expression of 11β-HSD1, 11β-HSD2 in nasal polyps were measured by Real-time PCR (RT-PCR), Western Blot and immunohistochemisty. According to the clinical data, the Logistic regression models and receiver operation characteristics (ROC) curves were used to explore the predictor for glucocorticoid response in CRSwNP. Results: The expression of 11β-HSD1 and 11β-HSD1/11β-HSD2 was higher in sensitive group than that of insensitive group, while the expression of 11β-HSD2 was lower (rank average was 26.08 vs 16.33, 27.24 vs 14.72, 18.66 vs 26.64, Z value was -2.511, 0.323, -2.059, respectively, all P<0.05). The endoscopic scores in CRSwNP group declined whereas the expression of 11β-HSD1/11β-HSD2 increased (r=0.528, P=0.001), while the cutoff value of the ratio of 11β-HSD1/11β-HSD2 was 2.290 (sensitivity was 79.17%, specificity was 88.89%). Conclusions: There is a positive correlation between the response of glucocorticoid and the ratio of 11β-HSD1/11β-HSD2, which could be used as a marker in predicting the level of tissue response to glucocorticoid therapy in CRSwNP.

Abstract
Objective: To explore the clinical features, diagnostic methods and therapeutic strategy of silent sinus syndrome (SSS). Methods: A retrospective study was made on eight SSS patients treated during 2013-2016 in Longgang ENT Hospital and Otorhinolaryngology Hospital of the First Affiliated Hospital of SUN Yat-sen University. The following clinical data, including demographic data, symptoms, history of trauma and surgery, signs, imaging examination, endoscopic surgery and postoperative outcomes, were analyzed to summarize the diagnosis and treatment experiences. Results: Eight SSS patients showed the following clinical features: the proportions of both sexes and sinus sides were 4 to 4; seven cases (7/8) were adult, with an average of (48.1±11.8)y; seven cases (7/8) had long history of trauma or surgery, with an average of (17.9±10.5)y; seven cases (7/8) cannot recall the exact course of SSS; six cases (6/8) had no nasal symptoms; eight cases (8/8) had unilateral ocular discomforts; eight cases (8/8) had signs of unilateral enophthalmos (2-5 mm), accompanied with hypoglobus; and by CT and MRI scanning, eight cases (8/8) showed the unilateral maxillary sinus outlet obstruction, sinus full opacification, sinus wall bony rarefaction, sinus wall contraction, sinus volume loss, and the ipsilateral orbital floor bowing descent and orbital volume increase. After treated by endoscopic sinus surgery and followed-up for one year, four cases were cured, and the other four improved; no intra- or post-operative complications occurred; and no individual need a two-stage orbital plastic reconstruction. Conclusions: SSS often develops in the unilateral maxillary sinus of adult patient with long history of trauma or surgery, but the nasal symptoms and signs are silent. Diagnostic for SSS depends on characteristic ocular sign and sinus CT imaging. Endoscopic sinus surgery helps to improve ocular and nasal signs and promote orbital self-reconstruction.

Abstract
Objective: To summarize the surgical techniques, benefits and limitations of transnasal endoscopic resection and optic nerve decompression for patients with optic neuropathy caused by fibro-osseous lesions. Methods: Eight patients with optic neuropathy caused by fibro-osseous lesions who accepted endoscopic surgery of either resection of the lesion or decompression of optic nerve in Otorhinolaryngology Hospital, First Affiliated Hospital of Sun Yat-sen University from 2007 to 2016 were retrospectively reviewed and followed until April, 2017. Analyses were performed on the pathology type, disease extent and disease duration, especially on the visual acuity and visual field changes before and after surgery. Results: Eight patients (5 male and 3 female) were included in this study, with a median age of 12 years old (8-19 years old). The median disease duration was 12 months (1-72 months). The visual acuity (VA) of five patients (40 cm/FC, 0.2, 0.1, 0.2, 10 cm/FC, respectively) improved after surgery (0.1, 0.3, 1.2, 0.1, 0.6, respectively), and one patient had no change of VA after the surgery. Two patients (0.02, hand movement, before surgery) became deprived of light perception (VA=0) immediately after surgery. One patient complicated with intra orbital hemorrhage because of anterior artery injury. No complications of cerebral spinal fluid leak, intra-ocular muscle injury, intra-cranial hemorrhage or brain tissue injury occurred. Conclusion: For the treatment of optic neuropathy caused by fibro-osseous lesions, transnasal endoscopic surgery might have a good outcome.

Abstract
To investigate genetic diversity and relationships of 101 faba bean (Vicia faba L.), landraces and varieties from different provinces of China and abroad were analyzed by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE). A total of 2625 unambiguous and stable bands from 101 germplasms were detected, and 36 different bands were classified according to the electrophoretic mobility patterns of the proteins as determined by the SDS-PAGE analysis, of which 16 were polymorphic. Besides the common bands, the protein bands of 92, 75, 62, 40, 34, 17, and 13 kDa presented the highest frequencies of 92.08, 90.10, 99.01, 95.05, 95.05, 98.02, and 95.05%, respectively. The other 29 polymorphic protein bands showed higher polymorphism with 16.09 polymorphic bands in average. The genetic similarity of the 101 genotypes tested varied from 0.6111 to 0.9722, with an average of 0.7122. Cluster analysis divided the 101 genotypes into six major clusters, which was consistent with the systematic classification of faba bean done in previous studies. The overall results indicated that SDS-PAGE was a useful tool for genetic diversity analysis and laid a solid foundation for future faba bean breeding.

Abstract
Many paddy fields have been contaminated by mercury (Hg) in mining areas of China. In this study, twenty-six rice cultivars and three Hg contaminated paddy fields in different geographic regions were selected for field trials and aimed to investigate the variations and similarities in total Hg (THg) and methylmercury (MeHg) accumulations in brown rice (seeds) across sites. Our results revealed widescale cultivar variation in THg (13-52 ng g(-1) at Wanshan) and MeHg (3.5-23 ng g(-1)) accumulation and %MeHg (17.7-89%) in seeds. The ability to translocate is an important factor in the levels of THg and MeHg in seed. Cultivar tended to stability in THg accumulation across sites. Some cultivars accumulated lower concentrations of both THg and MeHg in seeds at fields seriously contaminated by Hg. Present results suggest that appropriate cultivar selection is a possible way to reduce THg and MeHg accumulation in seeds of rice grown in Hg-contaminated regions.

Abstract
BACKGROUND Human induced pluripotent stem cells (iPSCs) possess remarkable self-renewal capacity and the potential to differentiate into novel cell types, such as mesenchymal stem cells (MSCs). iPSC-MSCs have been shown to enhance tissue regeneration and attenuate tissue ischaemia; however, their contribution to the immune regulation of Th2-skewed allergic rhinitis (AR) and asthma remains unclear. OBJECTIVE This study compared the immunomodulatory effects of iPSC-MSCs and bone marrow-derived MSCs (BM-MSCs) on lymphocyte proliferation, T-cell phenotypes and cytokine production in peripheral blood mononuclear cells (PBMCs) in patients with AR, and investigated the possible molecular mechanisms underlying the immunomodulatory properties of iPSC-MSCs. METHODS In co-cultures of PBMCs with iPSC-MSCs or BM-MSCs, lymphocyte proliferation was evaluated using 3H-thymidine (3H-TdR) uptake, carboxyfluorescein diacetate, succinimidyl ester (CFDA-SE) assays; the regulatory T-cell (Treg) phenotype was determined by flow cytometry, and cytokine levels were measured using an enzyme-linked immunosorbent assay. The immunomodulatory properties of both MSCs were further evaluated using NS398 and transwell experiments. RESULTS Similar to BM-MSCs, we determined that iPSC-MSCs significantly inhibit lymphocyte proliferation and promote Treg response in PBMCs (P < 0.05). Accordingly, the cytokine milieu (IFN-γ, IL-4, IL-5, IL-10 and IL-13) in the supernatants of PBMCs changed significantly (P < 0.05). The immunomodulatory properties of iPSC-MSCs and BM-MSCs were associated with prostaglandin E2 (PGE2) production and cell-cell contact. CONCLUSIONS These data demonstrate that iPSC-MSCs are capable of modulating T-cell phenotypes towards Th2 suppression through inducing Treg expansion, suggesting that iPSC-MSCs can be used as an alternative candidate to adult MSCs to treat allergic airway diseases.

Abstract
BACKGROUND The pathogenesis of nasal polyps is still unclear. There is increasing evidence indicating that Staphylococcal aureus (S. aureus) is associated with the formation of nasal polyps, but the mechanism has not been well documented to date. METHODS We stimulated cultured nasal polyps and turbinate tissues with Staphylococcal exotoxin B (SEB), detected the expression of pro-inflammatory cytokines (IL-2, IL-6, and IL-8) and T cell cytokines (IFN-gamma, IL-4, IL-5, IL-10, and IL-17) in the supernatants, and evaluated mRNA expression (T-bet, GATA-3, Foxp3, and RORgammat) and frequencies of CD4+CD25+ T regulatory cells (Tregs) in nasal tissues. We also evaluated the effects of blocking IL-6 with monoclonal antibodies to T cell profiles in cultured nasal tissues stimulated by SEB. RESULTS Levels of IL-6, IFN-gamma and IL-4 increased significantly in SEB-stimulated nasal polyps. Meanwhile, mRNA expressions of T-bet and GATA-3 were significantly up-regulated, while Foxp3 was inhibited and the frequencies of CD4+CD25+ Tregs were decreased after SEB stimulation. After blocking IL-6, the levels of IL-10 and Foxp3 mRNA, as well as the frequencies of CD4+CD25+ Tregs, were significantly increased, while IFN-gamma and IL-4 production and the mRNA expression of T-bet and GATA-3 were significantly inhibited. CONCLUSIONS SEB is able to modulate pro-inflammatory factors, T-helper type 1/Th2 profiles and suppress Treg activity in cultured nasal polyps, which were rescued by blocking IL-6 activity. Therefore, IL-6 is essential for SEB-induced Treg insufficiency in nasal polyps.

Abstract
OBJECTIVES Transnasal endoscopic optic nerve decompression was recommended to treat traumatic optic neuropathy as an effectively adjunctive procedure. The aim of this study was to assess the risks and benefits of salvage surgical decompression for complete vision loss (no light detection) after failure of mega-dose steroid therapy. DESIGN Retrospective study. SETTING Two hospitals in Guangzhou and Nanjing, China. PARTICIPANTS Forty-two patients of traumatic optic neuropathy with complete vision loss and failed to improve after steroid therapy for at least 3 days. MAIN OUTCOME MEASURES All patients were treated by transnasal endoscopic optic nerve decompression and received follow-up for at least 6 month. Vision improvement and complications were evaluated. RESULTS Transnasal endoscopic optic nerve decompression was performed successfully in 40 patients and was incomplete in two patients due to bleeding. Vision improved in four of 42 patients (9.5%) of traumatic optic neuropathy with complete vision loss and failed steroid therapy. Complications and sequelae included severe bleeding (two cases), cerebrospinal fluid rhinorrhea (one case), nasal polyps (seven cases), chronic sinusitis (four cases) and nasal synechia (17 cases). CONCLUSION Transnasal endoscopic optic nerve decompression was recommended as a minimally invasive, safe procedure, but complications and sequelae of the surgery should not be neglected. Based on the risk and benefit analysis, we conclude that the very poor surgical outcomes of this series do not support endoscopic optic nerve decompression for traumatic blindness.

Abstract
BACKGROUND To explore the significance of hepatitis B virus PreS1-Ag, PreS2-Ag, large protein (LP) detection and the prediction of viral replication. METHODS PreS1-Ag, PreS2-Ag, LP and HBV markers were measured by enzyme linked immunosorbent assay (ELISA) in 201 cases of infected serum. Serum HBV DNA level was quantitatively detected by real-time polymerase chain reaction (PCR). RESULTS There were significant differences in positive rate between the PreS1-Ag, PreS2-Ag, LP, and HBsAg; the positive rate of PreS2-Ag and LP were higher than that of the HBeAg. No significant differences were found in the positive rates between LP and the levels of HBV DNA and there was a positive correlation between quantitations of HBV DNA and HBV-LP. CONCLUSION Serum PreS1-Ag, PreS2-Ag and LP were laboratory markers that can accurately reflect HBV DNA reproduction, and were helpful complementarity to traditional HBV M. There is a close correlation between the number of copies of HBV DNA and the levels of HBV-LP.
