Abstract
OBJECTIVES The identification of structural variants and single-nucleotide variants is essential in finding molecular etiologies of monogenic genetic disorders. Whole-genome sequencing (WGS) is becoming more widespread in genetic disease diagnosis. However, data on its clinical utility remain limited in prenatal practice. We aimed to expand our understanding of implementing WGS in the genetic diagnosis of fetal structural anomalies. METHODS We employed trio WGS with a minimum coverage of 40× on the MGI DNBSEQ-T7 platform in a cohort of 17 fetuses presenting with aberrations detected by ultrasound, but uninformative findings of standard chromosomal microarray analysis (CMA) and exome sequencing (ES). RESULTS Causative genetic variants were identified in two families, with an increased diagnostic yield of 11.8% (2/17). Both were exon-level copy-number variants of small size (3.03 kb and 5.16 kb) and beyond the detection thresholds of CMA and ES. Moreover, to the best of our knowledge, we have described the first prenatal instance of the association of FGF8 with holoprosencephaly and facial deformities. CONCLUSIONS Our analysis demonstrates the clinical value of WGS in the diagnosis of the underlying etiology of fetuses with structural abnormalities, when routine genetic tests have failed to provide a diagnosis. Additionally, the novel variants and new fetal manifestations have expanded the mutational and phenotypic spectrums of BBS9 and FGF8. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Background Ischemic stroke (IS) is a leading cause of long-term disability and even mortality, threatening people's lives. Yinao Fujian (YNFJ) formula is a Traditional Chinese Medicine formula that has been widely used to treat patients with IS. However, the molecular mechanism of YNFJ for the treatment of IS is still elusive. Our study aimed to explore the potential protective effect and the underlying mechanisms of YNFJ on IS using a network pharmacology approach coupled with experimental validation. Materials and methods Effective compounds of YNFJ were collected from BATMAN-TCM and TCMSP databases, while IS targets were obtained from GeneCards, OMIM, TTD and DrugBank databases. The protein-protein interaction (PPI) network was constructed to further screen the hub targets of YNFJ in IS treatment. GO and KEGG enrichment analyses were used to identify the critical biological processes and signaling pathways of YNFJ for IS. Moreover, Nissl staining, HE, TTC staining and Tunel staining were used in the MCAO model to prove the neuroprotective effect of YNFJ. Oxidative damage, inflammatory factor release and related pathways were tested in MCAO rat model and hypoxia-induced BV2 cell model, respectively. Results We found that YNFJ treatment significantly alleviated MCAO-induced nerve damage and apoptosis. Then, network pharmacology screening combined with literature research revealed IL6, TNF, PTGS2, NFKBIA and NFE2L2 as the critical targets in a PPI network. Moreover, the top 20 signaling pathways and biological processes associated with the protective effects of YNFJ on IS were enriched through GO and KEGG analyses. Further analysis indicated that NF-κB and Nrf2/HO-1 signaling pathways might be highly involved in the protective effects of YNFJ on IS. Finally, in vitro and in vivo experiments confirmed that YNFJ inhibited the release of inflammatory factors (IL-6 and TNF-α) and MDA content, and increased the activity of SOD. In terms of the mechanism, YNFJ inhibited the release of inflammatory factors by suppressing the NF-κB pathway and decreased the expression of iNOS and COX-2 to protect microglia from inflammation damage. In addition, YNFJ initiated the dissociation of Keap-1 and Nrf2, and activated the downstream protein HO-1, NQO1, thus decreasing oxidative stress. Conclusion Taken together, the findings in our research showed that the protective effects of YNFJ on IS were mainly achieved by regulating the NF-κB and Nrf2/HO-1 signaling pathways to inhibit oxidative stress damage and inflammatory damage of microglia.

Abstract
Cerebral ischemic stroke is a high-risk disease and imposes heavy burdens on patients in china. Acupuncture has been used for thousands of years to treat motor dysfunction, cognitive disorder and language barrier caused by cerebral ischemic stroke. Acupoint lines, vertex middle line and anterior oblique line of vertex temple, are always employed to treat cerebral ischemic stroke. However, the mechanism of the two acupoint lines in relieving cerebral ischemic stroke needs further exploration. In the present study, scalp acupuncture treatment alleviated the motor dysfunction, brain damage, and cell death induced by middle cerebral artery occlusion (MCAO) in rats. Proteomics analysis and ultrastructure observation indicated that endoplasmic reticulum and lysosomes might involve in the mechanism of the scalp acupuncture treatment in suppressing MCAO-triggered neural deficits. Effect of the scalp acupuncture treatment on ER stress was then investigated and found that the activation of ER stress mediators, including PERK, IRE1, and ATF6, was downregulated after the scalp acupuncture treatment. Co-localisation analysis of KDEL and CD63 showed that the engulfment of ER fragments by lysosomes was accelerated by the scalp acupuncture treatment. Moreover, expression of pro-apoptotic protein CHOP, phosphorylated-JNK, cleaved capases-3 and -9 also decreased after the scalp acupuncture. In conclusion, the present study showed that scalp acupuncture of vertex middle line and anterior oblique line of vertex temple may alleviate cerebral ischemic stroke by inhibiting ER stress-accelerated apoptosis.

Abstract
Biologic drugs are used to treat a variety of cancers and chronic diseases. While most of these treatments are administered intravenously by trained healthcare professionals, a noticeable trend has emerged favoring subcutaneous (SC) administration. SC administration of biologics poses several challenges. Biologic drugs often require higher doses for optimal efficacy, surpassing the low volume capacity of traditional SC delivery methods like autoinjectors. Consequently, high concentrations of active ingredients are needed, creating time-consuming formulation obstacles. Alternatives to traditional SC delivery systems are therefore needed to support higher-volume biologic formulations and to reduce development time and other risks associated with high-concentration biologic formulations. Here, we outline key considerations for SC biologic drug formulations and delivery and explore a paradigm shift: the flexibility afforded by low-to-moderate-concentration drugs in high-volume formulations as an alternative to the traditionally difficult approach of high-concentration, low-volume SC formulation delivery.

Abstract
The effects of standard cow, goat and lactose-free cow milk powder on lactose intolerance symptoms and the nutritional status of dogs was studied. Forty adult Springer Spaniels with lactose intolerance were randomly allocated into four groups with ten dogs each and fed one of the milk powders or water for 21 d. The milk powders were reconstituted daily by diluting 10 g milk powder to 60 g water and 2 g milk powder/kg body weight was provided ad libitum and refusals were monitored daily. Lactose intolerance was assessed by faecal composition and pH, water and lactose contents. Biochemical markers for nutritional status were analysed. Feeding intolerance and lactose in faecal samples were observed in dogs fed the standard cow and goat milk powder, but not for the lactose-free milk powder or control groups. The high- and low-density lipoprotein cholesterol increased in all milk powder groups, while there were no other differences in nutritional status measurement. The results suggested that feeding lactose-free milk powder to dogs with lactose intolerance reduced the occurrence of symptoms, thereby enhancing the health and wellbeing of dogs.

Abstract
BACKGROUND Osteoarthritis is a common degenerative disease with a high incidence, high disability rate, and poor prognosis. Clinical studies have shown that Bushen Huoxue formula can relieve joint swelling and pain and improve limb function and joint mobility, but there is a lack of high-quality scientific basis. Using network pharmacology and molecular docking technology to study the mechanism of Bushen Huoxue formula in the treatment of osteoarthritis. METHODS First, the active ingredients and corresponding target predictions of the formula were obtained through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and the China National Knowledge Infrastructure. Meanwhile, the osteoarthritis disease targets were obtained through the genome annotation database platform (GeneCards) and the DrugBank database, and the target proteins obtained above were standardized using the Uniprot (https://www.uniprot.org) database standardization of names. Then, the Venn diagram was created by taking the intersection of the active ingredient and the target of the disease, and the "active ingredient-target" network was constructed and analyzed using Cytoscape 3.7.2 software. At the same time, the intersecting targets were imported into the Search Tool for the Retrieval of Interaction Gene/Proteins database to build a protein-protein interaction network and to screen the core targets; the intersecting targets were visualized by using the Database for Annotation, Visualization and Integrated Discovery 6.8 database for gene ontology functional analysis and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and construct the "active ingredient-target-pathway" network. Finally, the main active ingredients of the formula for tonifying the kidney and invigorating the blood were validated by molecular docking with the core targets. RESULTS A total of 194 active ingredients and 365 targets of the Bushen Huoxue formula were collected, 776 targets for osteoarthritis diseases and 96 targets for the intersection of active ingredients and diseases. The Kyoto Encyclopedia of Genes and Genomes enrichment analysis yielded 104 relevant pathways, including tumor necrosis factor signaling pathways, cancer signaling pathways, nucleotide-binding oligomerization domain-like receptor signaling pathways, Toll-like receptors signaling pathways, and osteoclast differentiation, apoptosis, T-cell receptor signaling pathway, and other related pathways. The molecular docking results showed good binding of the main active ingredients to the core targets. CONCLUSION This study shows that the treatment of osteoarthritis involves multicomponent, multitarget, and multipathway processes. The mechanism of anti-inflammatory, antioxidant, inhibition of cartilage matrix degradation, and reduction of subchondral bone destruction may be an important mechanism for the therapeutic effect.

Abstract
Cerebral infarction (CI), a common cerebrovascular disease worldwide, is caused by unknown factors common to many diseases, including hypokalemia, respiratory diseases, and lower extremity venous thrombosis. Tianma Gouteng (TMGT), a traditional Chinese Medicine (TCM) prescription, has been used for the clinical treatment of CI. In this study, high-performance liquid chromatography (HPLC) fingerprint analysis was used to detect and identify major chemical constituents of TMGT. TCMSP and BATMAN-TCM databases were used to screen for active TMGT constituent compounds, while the GeneCards database was used to screen for protein targets associated with CI. Next, GO and KEGG enrichment analysis of these core nodes were performed to determine the identities of key associated biological processes and signal pathways. Meanwhile, a total of six possible gene targets of TMGT, including NFKBIA, PPARG, IL6, IL1B, CXCL8, and HIF1A, were selected for further study using two cellular models of CI. For one model, PC12 cells were treated under oxygen and glucose deprivation (OGD) conditions to generate an OGD cellular model of CI, while for the other model, BV2 cells were stimulated with lipopolysaccharide (LPS) to generate a cellular model of CI-associated inflammation. Ultimately TMGT treatment increased PPARγ expression and downregulated the expression of p-P65, p-IκBα, and HIF-1α in both OGD-induced and LPS-induced cell models of CI. In addition, molecular docking analysis showed that one TMGT chemical constituent, quercetin, may be a bioactive TMGT compound with activity that may be associated with the alleviation of neuronal damage and neuroinflammation triggered by CI. Moreover, additional data obtained in this work revealed that TMGT could inhibit neuroinflammation and protect brain cells from OGD-induced and LPS-induced damage by altering HIF-1α/PPARγ/NF-κB pathway functions. Thus, targeting this pathway through TMGT administration to CI patients may be a strategy for alleviating nerve injury and neuroinflammation triggered by CI.

Abstract
BACKGROUND Post-stroke depression (PSD) is the most common mental health issue, affecting approximately 33% of stroke survivors. Tuina and acupuncture treatments are often combined to treat PSD; however, there has been no meta-analysis on their synergistic effect. Therefore, we aimed to perform a systematic review and meta-analysis to estimate the effectiveness of Tuina and acupuncture in PSD treatment. METHODS The following electronic databases will be searched: PubMed, the Cochrane Library, Embase, Web of Science, Medline, CNKI, Chinese Biomedical Literature Database, VIP, and Wan Fang databases. We will consider articles published between database initiation and April 2021. Clinical randomized controlled trials related to Tuina combined with acupuncture for post-stroke depression will be included in the study. Language is limited to Chinese and English. Research selection, data extraction, and research quality assessment were independently completed by 2 researchers. Data were synthesized using a fixed effect model or random effect model, depending on the heterogeneity test. The Hamilton depression rating scale (HDRS) and effective rate were the primary outcomes. The post-stroke depression rating scale (PSDRS), patient health questionnaire-9 (PHQ-9), and the incidence of adverse events will also be assessed as secondary outcomes. RevMan V.5.4 statistical software will be used for meta-analysis. If it is not appropriate for a meta-analysis, a descriptive analysis will be conducted. Data synthesis uses the risk ratio and the standardized or weighted average difference of continuous data to represent the results. RESULTS This study provides a high-quality synthesis to assess the effectiveness and safety of Tuina for post-stroke depression. CONCLUSION This systematic review will provide evidence to determine whether Tuina plus acupuncture is an effective and safe intervention for patients with post-stroke depression. ETHICS AND DISSEMINATION The protocol of the systematic review does not require ethical approval because it does not involve humans. This article will be published in peer-reviewed journals and presented at relevant conferences. SYSTEMATIC REVIEW REGISTRATION INPLASY202140098.

Abstract
BACKGROUND Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma have poorer outcomes after functional endoscopic sinus surgery (FESS) and higher recurrence rate. The aim of present study was to investigate the long-term clinical outcomes of extended surgical strategies for patients with recurrent CRSwNP and asthma. METHODS Eighty-one patients with CRSwNP and asthma were enrolled in this 5-year prospective study. They were randomly assigned to undergo FESS, radical endoscopic sinus surgery (RESS), or RESS+Draf 3 surgery. Disease severity and clinical outcomes were evaluated using symptoms scoring, endoscopic scoring system, computed tomography staging system, sinus-specific quality of life scores, tissue and peripheral blood eosinophil percentage, and pulmonary function tests. Baseline, 1-year, 3-year, and 5-year follow-up data were compared among the groups. RESULTS RESS and RESS+Draf 3 strategies yielded better short-term (1 year) outcomes than did FESS. FESS had a higher short-term recurrence rate, although recurrence rates were similarly high (95.6 - 96.1%) in all the groups at 5 years postoperatively. RESS and RESS+Draf 3 yielded a lower long-term revision surgery rate and a longer time to recurrence post-surgery than FESS, which was negatively correlated with tissue and peripheral blood eosinophil percentage. CONCLUSIONS CRSwNP with asthma is a systemic disease that inevitably recurs. Radical surgery prolongs recurrence time and improves olfaction, rhinorrhea, and quality of life in the short-term. Combining Draf 3 with RESS did not yield better clinical outcomes than RESS alone; thus, although RESS alone appears to be the best option, these findings need to be confirmed in further studies involving more patients, longer follow-up duration and stricter standardized medication use especially the adequate steroid irrigations.

Abstract
BACKGROUND Our previous study showed that convoluted cerebriform pattern (CCP)-based reverse tracing method in preoperative magnetic resonance imaging (MRI) is a reliable tool in predicting originating site of sinonasal inverted papilloma (SNIP). This study aimed to determine the underlying pathological mechanism of the preoperative MRI-CCP reverse tracing method by assessing the histopathological changes from the origin to the peripheral sites of SNIP. METHODOLOGY The originating site of SNIP was predicted by preoperative MRI in 30 consecutive patients suspected to have primary SNIP. Samples of SNIP originating and peripheral sites were processed by pathological staining for evaluation of stroma score, micro-vessel density (MVD), and tight junction proteins (claudin-5, zonula occludens (ZO)-1 and occludin) expression. RESULTS The originating site of SNIP was accurately predicted by preoperative MRI in all patients. Stroma scores, and MVD were significantly greater in the periphery of SNIP than in the originating site. In contrast, Claudin-5 expression in micro-vessels was greater at the originating site than the periphery. CONCLUSIONS More edematous stroma and intensive micro-vessels with defective tight junction in periphery of SNIP result in more contrast agent diffusing and CCP that can only be observed at the periphery of SNIP on T2 and contrast-enhanced T1 weighted MR images, which may be the mechanisms underlying the CCP reverse tracing method.

Abstract
IntroductionIt is uncertain whether treatment by recombinant human granulocyte macrophage colony-stimulating factor (rhGM-CSF) can promote healing of deep second-degree burns. This meta-analysis aimed to systematically review and assess randomised controlled trials (RCTs) that investigated the efficacy and safety of rhGM-CSF for treating deep second-degree burns.MethodsThis meta-analysis conformed to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. The PubMed, Cochrane Library, Medline and Embase databases and relevant references were systematically searched for RCTs (published up to November 2019). Main outcome measures included the wound healing rate, wound healing time and average optical densities of the vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). We performed a meta-analysis using fixed or random effects models.ResultsSeven RCTs comprising 982 patients with 1184 burns (652 patients received rhGM-CSF vs 532 controls) were included. Compared with standard wound care alone, the use of rhGM-CSF significantly reduced wound healing time by 4.77 days (weighted mean difference=−4.77; 95% CI −6.45 to −3.09; p<0.001) and significantly increased the wound healing rate on days 7, 10, 14 and 20 by 6.46%, 19.78%, 17.07% and 11.38%, respectively. There was no significant difference between the groups in the wound healing rate on day 28 and average optical densities of VEGF and FGF. No systematic adverse event occurred. Redder, more swollen and painful wounds were reported after using rhGM-CSF compared with the control.ConclusionsrhGM-CSF could be effective and safe for treating deep second-degree burns.

Abstract
Objective: To investigate the clinical characteristics and drug susceptibility test (DST) of patients infected with different nontuberculous mycobacteria (NTM). Methods: The patients with nontuberculous mycobacterial lung disease (NMLD) in Shanghai Pulmonary Hospital from March 2014 to March 2015 were studied retrospectively by analyzing the clinical characteristics, radiological features and DST results. A total of 201 NMLD patients [male 108, age(58±15) yrs] were enrolled into this study including 48 cases of M. Kansasii [male 13, age (52±16) yrs],46 cases of M. Abscess[male 46, age (57±16) yrs], 92 cases of M. Intracellulare [male 43, age (61±13) yrs], and 15 cases of M. Avium [male 6, age (67±10) yrs]. Clinical data were collected when the diagnosis was made and Chi-square test was used to compare the differences among 4 groups of patients. Bonferroni method was used for further pairwise comparisons. Results: There were significant differences among the 4 groups in the age(χ(2)=6.42, P<0.001) and the gender(χ(2)=49.18, P<0.001) of the patients. The history of bronchiectasis in the groups of M. Kansasii, M. Abscess, M. Intracellulare and M. Avium were 2/48, 31/46, 39/92 and 4/15 cases respectively(χ(2)=41.84, P<0.001). For the Gamma-interferon release assays (ELISA) (IGRA), the positive rate of IGRA in the groups of M. Kansasii, M. Abscess, M. Intracellulare and M. Avium were 83%(40/48), 30%(14/46), 23%(21/92) and 33% (5/15) respectively(χ(2)=50.96, P<0.001). The radiological features were significantly different in tree-in-bud(8/48, 35/46, 36/92 and 4/15 cases respectively, χ(2)=36.48, P<0.001), pleural thickness or mild effusion (21/48, 36/46, 69/92 and 7/15 cases, χ(2)=19.54, P<0.001), bronchiectasis (20/48, 39/46, 78/92 and 10/15 cases, P<0.001) and cavities (38/48, 21/46, 63/92 and 10/15 cases, χ(2)=12.38, P<0.001) among the 4 groups(M. Kansasii, M. Abscess, M. Intracellulare and M. Avium). The drug resistance rates of M. Kansasii to rifampin, ethambutanol and ofloxacin were 10%(5/48), 8%(4/48) and 15%(7/48) respectively; the resistance rates of M.Intracellulare to ethambutanol was 45%(41/92), and the resistance rates of M.Abscess were all over 80% to all anti-TB drugs. The results of pairwise comparisons showed that the male proportion(46/48) and IGRAs positive rate(40/48) of patients with M. Kansasii were higher than those of other groups, and the incidence of bronchiectasis(20/48) and pleural changes(21/48) was lower than those of other groups. The female ratio(33/46), history of bronchiectasis (31/46) and tree-in-bud sign of patients(35/46) with M. Abscess were higher than those of other groups. Conclusions: There were differences in the clinical manifestations and imaging features of 4 common NMLD diseases, which were helpful for clinical differentiation. The patients with M. Kansasii infection were mainly male, with a high IGRA positive rate and fewer lesions of bronchiectasis or pleural changes. Most of the patients with M. Abscess were female, with a previous history of bronchiectasis, and with most of the lesions showing tree-in-bud signs. The NTM species had a high rate of resistance to anti-TB drugs except M. Kansasii.

Abstract
BACKGROUND The diagnostic value of serum specific Immunoglobulin E (sIgE) and nasal allergen provocation test (NAPT) has been well investigated in local allergic rhinitis (LAR). We hypothesized that nasal local sIgE could be used for the diagnosis of LAR instead of NAPT. METHODS This was a prospective single center study. Overall, 212 chronic rhinitis patients were screened, of whom 73 were recruited based on negative findings for serum IgE and positive findings for local eosinophils. Ten healthy subjects were also recruited as controls. All participants completed questionnaires at recruitment to record their demographic data, nasal symptom severity, and physician-diagnosed comorbid asthma. Symptom severity was recorded using a visual analogue scale (VAS) of 10 cm and allergic status was assessed by serum sIgE. Nasal secretions were collected for analysis of local sIgE and eosinophils, and NAPT was performed for confirmation of LAR. RESULTS Overall, 14 patients demonstrated positive local sIgE results. Twelve of these patients had significantly higher local sIgE levels compared to controls, and also demonstrated positive NAPT results. The VAS scores, nasal airway resistance measured by active rhinomanometry, and the levels of local sIgE, ECP, histamine and leukotriene C4 were significantly increased from baseline values following NAPT. Sensitivity, specificity, and diagnostic accuracy of local sIgE for diagnosis of LAR were 91.7% respectively. CONCLUSIONS The measurement of local sIgE levels in nasal secretion is a reliable and effective diagnostic method for LAR.

Abstract
Background: Cigarette smoke have adverse effects in the control of asthma and chronic rhinosinusitis (CRS). Interleukin (IL)-17A, the signature cytokine of helper T 17 cells and group 3 innate lymphoid cells (ILC3), has been reported to link with resistance to therapy in airway inflammation. This study aimed to investigate the impact of cigarette smoking and IL-17A activation on the clinical outcomes of asthmatic patients with chronic rhinosinusitis.
Methods: 33 patients with CRS and asthma, including 15 smokers and 18 non-smokers, and 7 asthmatic patients without CRS and smoking were prospectively recruited. The Sino-Nasal Outcome Test-22 and Asthma Control Test were used to evaluate sinonasal symptoms and the level of asthma control, respectively. Real-time PCR and immunostaining were applied to evaluate the expression levels of IL-17A and associated immunological factors on surgically-obtained nasal tissues.
Results: Nasal surgery improved both sinonasal symptoms and asthma control. Compared to non-smokers, smokers showed poorer improvement in asthma control. The expression of IL-17A, IL-22, aryl hydrocarbon receptor (AhR), and ILC3 was increased in the nasal tissues of smokers with asthma and CRS. The expression of IL-17A mRNA was correlated with that of AhR and with positive nuclear AhR-AhR nuclear translocator staining cells, and that of cyclooxygenase-2 enzyme (COX-2). ILC3 cells were associated with IL-17A, IL-22, AhR, and COX-2 mRNA expression.
Conclusions: Cigarette smoking was related to lesser improvement in asthma control after nasal surgery and to IL-17A activation in the nasal tissues of patients with inflammatory airways.

Abstract
BACKGROUND Ceramide plays critical roles in cell proliferation, senescence and apoptosis, and is implicated in neurodegenerative diseases, etc. To clarify if ceramide plays some roles in retinal diseases, we established in vivo and in vitro retinal injury models with ceramide 2 (C2) treatment. In addition, Erythropoietin (EPO), which showed protective effects on retinal cells and blood-retinal barrier (BRB), was also tested for its protection and possible mechanism(s) in these models. METHODS Male Sprague-Dawley rats were divided into four groups, i.e., normal control, vehicle control, C2 treatment, and C2+EPO treatment. After intravitreal injection, the rats were examined for eye fundus, electroretinogram, histological study, and immunostaining, etc. In vitro, retinal neuronal cell line (R28) and the primary human retinal microvascular endothelial cells (HRMECs) were treated with C2, cell viability assay, transendothelial electrical resistance (TEER) and BRB-related molecules were studied to test the protective effect of EPO. RESULTS Intravitreal C2-treatment caused significant vision loss in rats, as reflected by reduced b-wave amplitude, increased TUNEL positive cells and GFAP immunostaining in retina. Another major retinal injury observed was BRB breakdown following C2- treatment. Such C2-induced injuries were further confirmed by in vitro study. When HRMECs were treated with C2, the TEER was significantly reduced. The mechanisms for C2 to induce such injuries might be through evidently increased expressions of the related molecules like plasmalemma vesicle-associated protein (PLVAP or PV-1), ecto- 5'-nucleotidase (CD73) and intercellular adhesion molecule-1 (ICAM-1), as observed in C2-treated R28 cells. All these injuries induced by C2 were significantly prevented by EPO both in vivo and in vitro, and its protective mechanisms here might be, in addition to neuroprotective, closely related to its maintenance of BRB integrity, through reducing the expressions of PV-1, CD73 and ICAM-1. CONCLUSION C2 could induce severe retinal injury, and such injuries could be effectively prevented by EPO treatment.

Abstract
High-risk human papillomavirus (HPV) is an important pathogenic factor for cervical cancer and understanding the mechanism of HPV gene transcription is important for the prevention and therapy of HPV related cervical cancer. This study aimed to investigate the role of nitric oxide (NO) in the regulation of HPV gene transcription. SiHa cells containing integrated HPV16 were treated with NO donor DETA-NO and cell proliferation and cytotoxicity were determined. HPV gene transcription was detected by real-time PCR. We found no significant cytotoxic effects on SiHa cells when the concentration of DETA-NO was less than 0.5 mmol/l. The transcription of HPV E6 gene was inhibited by DETA-NO in a dose-dependent manner and the best inhibitory effect was observed at 0.5 mmol/l DETA-NO. In addition, ERK inhibitor U0126 decreased the transcription of HPV E6 gene at the concentration of 30 μmol/l. In conclusion, NO inhibits the transcription of HPV E6 gene and probably involves MAPK signaling pathway. Keywords: SiHa cells; nitric oxide; MAPK pathway; HPV transcription.

Abstract
Genetic alterations associated with prostate cancer (PCa) may be identified by sequencing metastatic tumour genomes to identify molecular markers at this lethal stage of disease. Previously, we characterized somatic alterations in metastatic tumours in the methylcytosine dioxygenase ten-eleven translocation 2 (TET2), which is altered in 5-15% of myeloid, kidney, colon and PCas. Genome-wide association studies previously identified non-coding risk variants associated with PCa and melanoma. We perform fine-mapping of PCa risk across TET2 using genotypes from the PEGASUS case-control cohort and identify six new risk variants in introns 1 and 2. Oligonucleotides containing two risk variants are bound by the transcription factor octamer-binding protein 1 (Oct1/POU2F1) and TET2 and Oct1 expression are positively correlated in prostate tumours. TET2 is expressed in normal prostate tissue and reduced in a subset of tumours from the Cancer Genome Atlas (TCGA). Small interfering RNA-mediated TET2 knockdown (KD) increases LNCaP cell proliferation, migration and wound healing, verifying loss drives a cancer phenotype. Endogenous TET2 bound the androgen receptor (AR) and AR-coactivator proteins in LNCaP cell extracts, and TET2 KD increases prostate-specific antigen (KLK3/PSA) expression. Published data reveal TET2 binding sites and hydroxymethylcytosine proximal to KLK3. A gene co-expression network identified using TCGA prostate tumour RNA-sequencing identifies co-regulated cancer genes associated with 2-oxoglutarate (2-OG) and succinate metabolism, including TET2, lysine demethylase (KDM) KDM6A, BRCA1-associated BAP1, and citric acid cycle enzymes IDH1/2, SDHA/B, and FH. The co-expression signature is conserved across 31 TCGA cancers suggesting a putative role for TET2 as an energy sensor (of 2-OG) that modifies aspects of androgen-AR signalling. Decreased TET2 mRNA expression in TCGA PCa tumours is strongly associated with reduced patient survival, indicating reduced expression in tumours may be an informative biomarker of disease progression and perhaps metastatic disease.

Abstract
BACKGROUND Eplerenone (CAS 107724-20-9) is the first highly selective aldosterone receptor blocker and is used worldwide for treatment of hypertension and heart failure. OBJECTIVE The objective of this study was to investigate the eplerenone pharmacokinetics in healthy Chinese subjects and assess the dose proportionality over the therapeutic dose range. METHODS A single-dose, randomized, 6-sequence, 3-treatment, 3-period crossover, open label study was conducted in 12 healthy Chinese subjects, who received 3 doses of eplerenone in random order (25, 50, 100 mg). The power model was used to evaluate the dose proportionality of eplerenone. The pharmacokinetic study of multiple-dose of eplerenone was also conducted. RESULTS After single-dose oral administration, the mean C max value increased from 489 to 1 641 ng/mL, and the mean AUC 0-t value increased from 3 030 to 10 893 ng/mL·h with an increase in dose from 25 to 100 mg, respectively. The mean value for terminal T 1/2 was approximate 3 h with no significant differences among different dose groups. Though dose proportionality of eplerenone was inconclusive in Chinese subjects over the dose range of 25-100 mg, the maximal proportionality dose range (ρ1) was 2.06 based on power model. Steady state could achieve within at least 4 days and no accumulation was observed after multiple-dose of eplerenone. CONCLUSION Dose proportionality was inconclusive in over the dose range of 25-100 mg; however, linear pharmacokinetics could be considered when dose ratio is no more than 2.06.

Abstract
Oxidative stress is central to the pathology of several neurodegenerative diseases, including Parkinson's disease (PD), and therapeutics designed to enhance antioxidant potential could have clinical value. In this study, we investigated whether dimethyl fumarate (DMF) has therapeutic effects in cellular and animal model of PD, and explore the role of nuclear transcription factor related to NF-E2 (Nrf2) in this process. Treatment of animals and dopaminergic SH-SY5Y cells with DMF resulted in increased nuclear levels of active Nrf2, with subsequent upregulation of antioxidant target genes. The cytotoxicity of 6-hydroxydopamine (6-OHDA) was reduced by pre-treatment with DMF in SH-SY5Y cells. The increase in the reactive oxygen species caused by 6-OHDA treatment was also attenuated by DMF in SH-SY5Y cells. The neuroprotective effects of DMF against 6-OHDA neurotoxicity were dependent on Nrf2, since treatment with Nrf2 siRNA failed to block against 6-OHDA neurotoxicity and induce Nrf2-dependent cytoprotective genes in SH-SY5Y cells. In vivo, DMF oral administration was shown to upregulate mRNA and protein levels of Nrf2 and Nrf2-regulated cytoprotective genes, attenuate 6-OHDA induced striatal oxidative stress and inflammation in C57BL/6 mice. Moreover, DMF ameliorated dopaminergic neurotoxicity in 6-OHDA-induced PD animal models as evidenced by amelioration of locomotor dysfunction, loss in striatal dopamine, and reductions in dopaminergic neurons in the substantia nigra and striatum. Taken together, these data strongly suggest that DMF may be beneficial for the treatment of neurodegenerative diseases like PD.

Abstract
The purpose of this study is to enhance the dissolution rate of prednisone by co-grinding with Neusilin to form a complex that can be incorporated into a mini-tablet formulation for pediatrics. Prednisone-Neusilin complex was co-grinded at various ratios (1:1, 1:3, 1:5, and 1:7). The physicochemical properties of the complex were characterized by various analytical techniques including: differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD), scanning electron microscope (SEM), particle size, surface area, solubility, and dissolution rate. The co-grinded prednisone-Neusilin complex (1:7) was blended with other excipients and was formulated into a 2-mm diameter mini-tablet. The mini-tablets were further evaluated for thickness, weight, content uniformity, and dissolution rate. To improve taste masking and stability, mini-tablets were coated by dip coating with Eudragit® EPO solution. DSC and XRPD results showed that prednisone was transformed from crystalline state into amorphous state after co-grinding with Neusilin. Particle size, surface area, and SEM results confirmed that prednisone was adsorbed to Neusilin's surface. Co-grinded prednisone-Neusilin complex (1:7) had a solubility of 0.24 mg/mL and 90% dissolved within 20 min as compared to crystalline prednisone which had a solubility of 0.117 mg/mL and 30% dissolved within 20 min. The mini-tablets containing co-grinded prednisone-Neusilin complex (1:7) exhibited acceptable physicochemical and mechanical properties including dissolution rate enhancement. These mini-tablets were successfully dip coated in Eudragit® EPO solution to mask the taste of the drug during swallowing. This work illustrates the potential use of co-grinded prednisone-Neusilin to enhance solubility and dissolution rate as well as incorporation into a mini-tablet formulation for pediatric use.

Abstract
α-synuclein (α-Syn) is a chaperone-like protein that is highly implicated in Parkinson's disease (PD) as well as in dementia with Lewy bodies (DLB). Rare forms of PD occur in individuals with mutations of α-Syn or triplication of wild type α-Syn, and in both PD and DLB the intraneuronal inclusions known as Lewy bodies contain aggregated α-Syn that is highly phosphorylated on serine 129. In neuronal cells and in the brains of α-Syn overexpressing transgenic mice, soluble α-Syn stimulates the activity of protein phosphatase 2A (PP2A), a major serine/threonine phosphatase. Serine 129 phosphorylation of α-Syn attenuates its stimulatory effects on PP2A and also accelerates α-Syn aggregation; however, it is unknown if aggregation of α-Syn into Lewy bodies impairs PP2A activity. To assess for this, we measured the impact of α-Syn aggregation on PP2A activity in vitro and in vivo. In cell-free assays, aggregated α-Syn had ∼50% less PP2A stimulatory effects than soluble recombinant α-Syn. Similarly in DLB and α-Syn triplication brains, which contain robust α-Syn aggregation with high levels of serine 129 phosphorylation, PP2A activity was also ∼50% attenuated. As α-Syn normally stimulates PP2A activity, our data suggest that overexpression of α-Syn or sequestration of α-Syn into Lewy bodies has the potential to alter the phosphorylation state of key PP2A substrates; raising the possibility that all forms of synucleinopathy will benefit from treatments aimed at optimizing PP2A activity.

Abstract
A simple and sensitive HPLC method was developed to determine cefdinir (CAS 91832-40-5) in human plasma. The method was validated by investigating the accuracy and precision for intra- and inter-day runs in a linear concentration from 0.05-2.0 µg/ml. The object of this study was to compare the bioavailability of cefdinir capsule (reference) and cefdinir granule (test) containing 100 mg of cefdinir. A randomized, open-label, single-dose, 2-way crossover bioequivalence study in 20 healthy, Chinese, male subjects was conducted. A 1-week wash-out period was applied. Blood samples were collected before and with 10 h after drug administration. The formulations were compared using the following pharmacokinetic parameters: AUC0-t, AUC0-∞ and C max. The 90% confidence interval (CI) of the ratios of log-transformed AUC0-t and AUC0-∞ were used to assess bioequivalence between the 2 formulations using the equivalence interval of 80 and 125%. The results showed that the 90% CI of the ratios of AUC0-t, AUC0-∞ and C max were 102.5% (94.7-111.0%), 103.4% (94.8-112.7%) and 106.4% (97.0-116.7%), respectively, which indicated 2 formulations of cefidinir are bioequivalent. Both treatments showed similar tolerability and safety.

Abstract
Stem cells possess the dual properties of self-renewal and pluripotency. Self-renewal affords these populations the luxury of self-propagation, whereas pluripotency allows them to produce the multitude of cell types found in the body. Protection of the stem cell population from damage or death is critical because these cells need to remain intact throughout the life of an organism. The principal mechanism of protection is through expression of multifunctional efflux transporters--the adenosine triphosphate-binding cassette (ABC) transporters that are the "guardians" of the stem cell population. Ironically, it has been shown that these ABC efflux pumps also afford protection to cancer stem cells (CSCs), shielding them from the adverse effects of chemotherapeutic insult. It is therefore imperative to gain a better understanding of the mechanisms involved in the resistance of stem cells to chemotherapy, which could lead to the discovery of new therapeutic targets and improvement of current anticancer strategies.

Abstract
OBJECTIVE To improve understanding of TRPV4-associated axonal Charcot-Marie-Tooth (CMT) neuropathy phenotypes and their debated pathologic mechanism. METHODS A total of 17 CMT2C phenotypic families with vocal cord and diaphragmatic involvement and 36 clinically undifferentiated CMT2 subjects underwent sequencing analysis of the coding region of TRPV4. Functional studies of mutant proteins were performed using transiently transfected cells for TRPV4 subcellular localization, basal and stimulated Ca(2+) channel analysis, and cell viability assay with or without channel blockade. RESULTS Two TRPV4 mutations R232C and R316H from 17 CMT2C families were identified in the ankyrin repeat domains. The R316H is a novel de novo mutation found in a patient with CMT2C phenotype. The family with R232C mutation had individuals with and without vocal cord and diaphragm involvement. Both mutant TRPV4 proteins had normal subcellular localization in HEK293 and HeLa cells. Cells transfected with R232C and R316H displayed increased intracellular Ca(2+) levels and reversible cell death by the TRPV channel antagonist, ruthenium red. CONCLUSION TRPV4 ankyrin domain alterations including a novel de novo mutation cause axonal CMT2. Individuals with the same mutation may have nondistinct CMT2 or have phenotypic CMT2C with vocal cord paresis. Reversible hypercalcemic gain-of-function of mutant TRPV4 instead of loss-of-function appears to be pathologically important. The reversibility of cell death by channel blockade provides an attractive area of investigation in consideration of treatable axonal degeneration.

Abstract
Vertical transmission of hepatitis B virus (HBV) has been proposed to play an important role in mother-to-child transmission, although the extent to which vertical transmission via oocytes contributes to neonatal HBV infection remains unknown. Ovarian biopsies were collected during caesarean sections in 68 clinically asymptomatic pregnant women who were carriers of HBV. The presence of hepatitis B surface antigen (HBsAg) in the ova of pregnant women was determined by immunohistochemistry. Serum markers of HBV infection in pregnant women and their neonates were analysed. It was found that, of 68 women, the ova were positive for HBsAg in only one woman and her neonate was negative for any serum HBV markers 3 days after birth. Of 68 neonates, one was positive for serum HBV markers 3 days after birth and his mother's ova were negative for HBsAg. These findings indicate that vertical transmission via oocytes may not be the major route of HBV intra-uterine infection.

Abstract
Data from certain leukemias as well as brain and breast cancer indicate that there is a small population of tumor cells with "stem cell" characteristics and the capacity for self-renewal. The self-renewing cells have many of the properties of normal stem cells and have been termed "cancer stem cells". These cancer stem cells make up as few as 1% of the cells in a tumor, making them difficult to detect and study. Like normal stem cells, cancer stem cells have a number of properties permitting them to survive traditional cancer chemotherapy and radiation therapy. These cells express high levels of ATP-binding cassette (ABC) drug transporters, providing for a level of resistance; are relatively quiescent; have higher levels of DNA repair and a lowered ability to enter apoptosis. Combined cancer therapy approaches targeting the cancer stem cells and the non-stem cells may be developed with increased efficacy. Efforts to target the Hedgehog/Patched pathway, critical to embryonic growth and differentiation, and the ABCG2 drug efflux transporter will be presented.

Abstract
The current study investigated the phosphorylation of mitogen-activated protein kinases (MAPKs) as well as pro- and anti-apoptotic proteins in adriamycin (ADR)-induced cardiomyopathy (AIC) and heart failure in rats. Modulatory effects of antioxidant probucol on the activation of MAPKs were also examined. Male rats were administered with ADR (15 mg/kg body wt ip, over 2 wk) with and without probucol (120 mg/kg body wt for 4 wk ip). Hearts from these animals were studied at 1- to 24-h as well as at 3-wk posttreatment durations. In the 3-wk group, ADR depressed cardiac function, increased left ventricular end-diastolic pressure (LVEDP), and caused dyspnea and mortality. These changes were prevented by probucol. Phosphorylation of extracellular signal-regulated kinase (ERK)1/2, in the early stage of AIC, showed a biphasic response, with a maximum increase to 513% seen at 4 h, followed by a decrease to 66.8% at 3 wk after the last injection of ADR. Phosphorylation of p38 and c-Jun NH2-terminal kinases (JNKs) showed a steady increase through 2, 4, and 24 h and 3 wk (116% to 148%). In gene microarray analysis at 3 wk (heart failure stage), mRNA expression for both ERK1/2 and p38 kinases was decreased, whereas JNK mRNA was undetectable. Probucol completely prevented these MAPK changes. Activation of caspase-3 as well as the increase in the ratio of Bax to Bcl-xl were seen at early time points (1–24 h) as well as in the heart failure stage (3 wk). It is suggested that a transient increase in ERK1/2 at a shorter interval indicate an early adaptive response, and failure of this response corresponded with heart failure. In contrast, a gradual and persistent increase in p38 and JNK MAPKs as well as in caspase-3 and the Bax-to-Bcl-xl ratio may contribute in the initiation of apoptosis and progression of heart failure. Because probucol modulated changes in cellular signaling pathways and cardiac function, it is likely that oxidative stress plays a key role in AIC and heart failure.

Abstract
Heart failure due to a variety of causes is accompanied by an upregulation of cytokines, such as tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and interleukin-6 (IL-6). Adriamycin-induced cardiomyopathy (AIC) and heart failure is an important clinical problem. The current study investigated the expression of these cytokines in AIC and heart failure in rats. Both early and late stages of AIC was produced in rats. Myocardial gene expressions for TNF-alpha, IL-1beta and IL-6 were examined with DNA microarrays and RT-PCR. Protein levels of these cytokines in both the plasma and the myocardium were also examined by ELISA. In the early stage, myocardial mRNA expression of IL-1beta showed significant increase at 4 and 24 h, peaking at 4 h, while TNF-alpha did not change and IL-6 was undetectable. The protein levels of these three genes did not show any upregulation in the plasma or the heart. In the late stage, heart failure was confirmed by clinical signs as well as homodynamic changes. In this stage, plasma protein levels for TNF-alpha, IL-1beta and IL-6 were not changed. However, myocardial TNF-alpha mRNA expression and protein levels were significantly decreased, while both IL-1beta mRNA and protein levels were not different compared to the control group. IL-6 mRNA expression was undetectable in both normal and adriamycin-treated hearts while its protein level was not changed by adriamycin. Positive control using lipopolysaccharides (LPS) treatment (0.5 mg/kg body weight) for 2 h resulted in a significant increase in these three cytokines in the heart and plasma. These data suggest that an upregulation of cytokines may not be involved in AIC. Heart failure may in fact be accentuated by a downregulation of myocardial TNF-alpha.

Abstract
Separation of the water-soluble fraction of peanut skins led to the isolation of 8 flavonoids and two novel indole alkaloids. Two new flavonoid glycosides have been identified as isorhamnetin 3-O-[2-O-beta-glucopyranosyl-6-O-alpha-rhamnopyranosyl]- beta-glucopyranoside and 3',5,7-trihydroxyisoflavone-4'-methoxy-3'-O-beta-glucopyranoside. Two alkaloids are 2-methoxyl-3-(3-indolyl)-propionic acid and 2-hydroxyl-3-[3-(1-N-methyl)-indolyl]-propionic acid. These isolated flavonoids were evaluated for their free radical scavenging activity and protein glycation inhibitory effects.

Abstract
Alternative RNA processing is a mechanism for creation of protein diversity through selective inclusion or exclusion of RNA sequence during posttranscriptional processing. More than one-third of human pre-mRNAs undergo alternative RNA processing modification, making this a ubiquitous biological process. The protein isoforms produced have distinct and sometimes opposite functions, underscoring the importance of this process. This review focuses on important endocrine genes regulated by alternative RNA processing. We discuss how diverse events such as spermatogenesis or GH action are regulated by this process. We focus on several endocrine (calcitonin/calcitonin gene-related peptide) and nonendocrine (Drosophila doublesex and P-element and mouse c-src) examples to highlight recent progress in the elucidation of molecular mechanisms regulating this process. Finally, we outline methods (model systems and techniques) used by investigators in this field to study processing of individual pre-mRNAS:

Abstract
During virus entry, herpes simplex virus (HSV) glycoprotein D (gD) binds to one of several human cellular receptors. One of these, herpesvirus entry mediator A (HveA), is a member of the tumor necrosis factor receptor (TNFR) superfamily, and its ectodomain contains four characteristic cysteine-rich pseudorepeat (CRP) elements. We previously showed that gD binds the ectodomain of HveA expressed as a truncated, soluble protein [HveA(200t)]. To localize the gD-binding domain of HveA, we expressed three additional soluble forms of HveA consisting of the first CRP [HveA(76t)], the second CRP [HveA(77-120t)], or the first and second CRPs [HveA(120t)]. Biosensor and enzyme-linked immunosorbent assay studies showed that gD bound to HveA(120t) and HveA(200t) with the same affinity. However, gD did not bind to HveA(76t) or HveA(77-120t). Furthermore, HveA(200t) and HveA(120t), but not HveA(76t) or HveA(77-120t), blocked herpes simplex virus (HSV) entry into CHO cells expressing HveA. We also generated six monoclonal antibodies (MAbs) against HveA(200t). MAbs CW1, -2, and -4 bound linear epitopes within the second CRP, while CW7 and -8 bound linear epitopes within the third or fourth CRPs. None of these MAbs blocked the binding of gD to HveA. In contrast, MAb CW3 recognized a discontinuous epitope within the first CRP of HveA, blocked the binding of gD to HveA, and exhibited a limited ability to block virus entry into cells expressing HveA, suggesting that the first domain of HveA contains at least a portion of the gD binding site. The inability of gD to bind HveA(76t) suggests that additional amino acid residues of the gD binding site may reside within the second CRP.

Abstract
The human herpesvirus entry mediator C (HveC), also known as the poliovirus receptor-related protein 1 (PRR1) and as nectin-1, allows the entry of herpes simplex virus type 1 (HSV-1) and HSV-2 into mammalian cells. The interaction of virus envelope glycoprotein D (gD) with such a receptor is an essential step in the process leading to membrane fusion. HveC is a member of the immunoglobulin (Ig) superfamily and contains three Ig-like domains in its extracellular portion. The gD binding site is located within the first Ig-like domain (V domain) of HveC. We generated a panel of monoclonal antibodies (MAbs) against the ectodomain of HveC. Eleven of these, which detect linear or conformational epitopes within the V domain, were used to map a gD binding site. They allowed the detection of HveC by enzyme-linked immunosorbent assay, Western blotting, and biosensor analysis or directly on the surface of HeLa cells and human neuroblastoma cell lines, as well as simian Vero cells. The anti-HveC V-domain MAbs CK6, CK8, and CK41, as well as the previously described MAb R1.302, blocked HSV entry. Their binding to soluble HveC was blocked by the association of gD with the receptor, indicating that their epitopes overlap a gD binding site. Competition assays on an optical biosensor showed that CK6 and CK8 (linear epitopes) inhibited the binding of CK41 and R1.302 (conformational epitopes) to HveC and vice versa. Epitope mapping showed that CK6 and CK8 bound between residues 80 and 104 of HveC, suggesting that part of the gD binding site colocalizes in the same region.
