Abstract
One new compound with an isoindolinone skeleton, along with erinacines A, C, and S, was isolated from the mycelia of Hericium erinaceus, an edible fungus with a long history of use in traditional Chinese medicine. Based on analysis of MS and NMR spectral data, the structure of the compound was identified as (2E,6E)-8-(2-(1-carboxy-3-methylbutyl)-4,6-dihydroxy-1-oxoisoindolin-5-yl)-2,6-dimethylocta-2,6-dienoic acid. In light of this discovery, we have given this compound the name erinacerin W. Using a co-culture in vitro LPS-activated BV2 microglia-induced SH-SY5Y neuroinflammation model, the results showed that erinacerin W demonstrated protection against the LPS-activated BV-2 cell-induced overexpression of IL-6, IL-1β, and TNF-α on SH-SY5Y cells. This finding may provide potential therapeutic approaches for central nervous disorders.

Abstract
Objective: To analyze the clinical pathological and genetic mutation characteristics of conjunctival lymphoepithelial carcinoma. Methods: A retrospective case series study was conducted. Data from three patients diagnosed with conjunctival lymphoepithelial carcinoma and treated with tumor resection surgery at Tianjin Eye Hospital from January 2006 to December 2022 were collected. Four paraffin specimens (including one patient undergoing two surgeries) were subjected to immunohistochemical staining for epithelial antigen and lymphocytic antigen. Epstein-Barr virus (EBV)-encoded RNA (EBER) was detected using in situ hybridization, and whole-exome sequencing was performed on three specimens from two patients using next-generation sequencing methods. Results: All three patients were males aged over 65, with a disease duration ranging from 3 to 44 months. The tumors were unilateral, located on the bulbar or limbal conjunctiva, appearing red, with a maximum diameter of 4-20 mm. Imaging examinations revealed anterior location of the tumors with no involvement of the orbital bone, extraocular muscles, optic nerve, or paranasal sinuses. No local lymph node metastasis was observed in any patient. Pathological findings included undifferentiated carcinoma nests with significant reactive lymphocytic and plasma cell infiltration. Tumor cells were positive for pan-cytokeratin (CK-pan), epithelial membrane antigen (EMA), tumor protein 40 (p40), and tumor protein 63 (p63), with a cell proliferation index (Ki67) exceeding 80%. Cluster of differentiation 20 (CD20), CD3, and CD8 were positive for lymphocytes. In situ hybridization showed partial tumor cell expression of EBER in two specimens of one patient. Whole-exome sequencing revealed 58, 50, and 36 mutated genes in the three specimens, with enriched signaling pathways including melanoma signaling pathway, Notch1 signaling pathway, and RHOQ GTP cycle; enriched biochemical processes included amino acid starvation response, programmed cell death, regulation of lipid synthesis, sodium ion transport, and chromosome segregation. The common mutated gene in all three specimens was SZT2, and SZT2 was involved in the amino acid starvation response. One patient underwent a second complete resection surgery 40 months after partial excision, while the other two underwent complete resection surgery without recurrence. Two patients did not undergo radiation or chemotherapy, and one was lost to follow-up. Conclusions: Conjunctival lymphoepithelial carcinoma is associated with prominent lymphocytic and plasma cell infiltration, some cases are associated with EBV infection, and SZT2 mutations are present in conjunctival lymphoepithelial carcinoma.

Abstract
Enterovirus D68 (EV-D68), belonging to the genus Enterovirus of the Picornavirus family, is an emerging pathogen that can cause neurological and respiratory diseases in children. However, there is little understanding of the pathogenesis of EV-D68, and no effective vaccine or drug for the prevention or treatment of the diseases caused by this virus is available. Autophagy is a cellular process that targets cytoplasmic proteins or organelles to the lysosomes for degradation. Enteroviruses strategically harness the host autophagy pathway to facilitate the completion of their life cycle. Therefore, we selected an autophagy compound library to screen for autophagy-related compounds that may affect viral growth. By using the neutralization screening assay, we identified a compound, 'licochalcone A' that significantly inhibited EV-D68 replication. To investigate the mechanism by which licochalcone A inhibits EV-D68 replication and to identify the viral life cycle stage it inhibits, the time-of-addition, viral attachment, viral entry, and dual-luciferase reporter assays were performed. The results of the time-of-addition assay showed that licochalcone A, a characteristic chalcone found in liquorice roots and widely used in traditional Chinese medicine, inhibits EV-D68 replication during the early stages of the viral life cycle, while those of the dual-luciferase reporter assay showed that licochalcone A does not regulate viral attachment and entry, but inhibits EV-D68 IRES-dependent translation. Licochalcone A also inhibited enterovirus A71 and coxsackievirus B3 but did not significantly inhibit dengue virus 2 or human coronavirus 229E replication. Licochalcone A regulates IRES translation to inhibit EV-D68 viral replication.

Abstract
Human neutrophil elastase (HNE) overexpression has a crucial role in most acute inflammation and alpha1-antitrypsin deficiency syndromes observed in humans, triggering neutrophil invasion and activation of macrophage inflammatory and proteolytic effects, leading to tissue damage. Manipulating HNE level homeostasis could potentially help treat neutrophilic inflammation. Previous studies have shown that sirtinol (1) has a specific influence on HNE and potently attenuates acute lung injury and hepatic injury mediated by lipopolysaccharide or trauma hemorrhage. Therefore, 1 was chosen as the model structure to obtain more potent anti-HNE agents. In the present study, we synthesized a series of sirtinol analogues and determined their inhibitory effects on HNE. Structure-activity relationship (SAR) studies showed that swapping the imine and methyl groups of the sirtinol scaffold with diazene and carboxyl groups, respectively, enhances the HNE inhibiting potency. Compound 29 exhibited the highest potency in the SAR study and showed dual inhibitory effects on HNE and proteinase 3 with IC50 values of 4.91 and 20.69 µM, respectively. Furthermore, 29 was confirmed to have dual impacts on inhibiting O2•- generation and elastase release in cell-based assays with IC50 values of 0.90 and 1.86 µM, respectively. These findings suggest that 29 is a promising candidate for developing HNE inhibitors in the treatment of neutrophilic inflammatory diseases.

Abstract
BACKGROUND Human enteroviruses A71 (EV-A71) and D68 (EV-D68) are the suspected causative agents of hand-foot-and-mouth disease, aseptic meningitis, encephalitis, acute flaccid myelitis, and acute flaccid paralysis in children. Until now, no cure nor mucosal vaccine existed for EV-A71 and EV-D68. Novel mucosal bivalent vaccines are highly important for preventing EV-A71 and EV-D68 infections. METHODS In this study, formalin-inactivated EV-A71 and EV-D68 were used as antigens, while PS-G, a polysaccharide from Ganoderma lucidum, was used as an adjuvant. Natural polysaccharides have the characteristics of intrinsic immunomodulation, biocompatibility, low toxicity, and safety. Mice were immunized intranasally with PBS, EV-A71, EV-D68, or EV-A71 + EV-D68, with or without PS-G as an adjuvant. RESULTS The EV-A71 + EV-D68 bivalent vaccine generated considerable EV-A71- and EV-D68-specific IgG and IgA titres in the sera, nasal washes, saliva, bronchoalveolar lavage fluid, and feces. These antibodies neutralized EV-D68 and EV-A71 infectivity. They also cross-neutralized infections by different EV-D68 and EV-A71 sub-genotypes. Furthermore, compared with the PBS group, EV-A71 + EV-D68 + PS-G-vaccinated mice exhibited an increased number of EV-D68- and EV-A71-specific IgA- and IgG-producing cells. In addition, T-cell proliferative responses, and IFN-γ and IL-17 secretion in the spleen were substantially induced when PS-G was used as an adjuvant with EV-A71 + EV-D68. Finally, in vivo challenge experiments demonstrated that the immune sera induced by EV-A71 + EV-D68 + PS-G conferred protection in neonate mice against lethal EV-A71 and EV-D68 challenges as indicated by the increased survival rate and decreased clinical score and viral RNA tissue expression. Taken together, all EV-A71/EV-D68 + PS-G-immunized mice developed potent specific humoral, mucosal, and cellular immune responses to EV-D68 and EV-A71 and were protected against them. CONCLUSIONS These findings demonstrated that PS-G can be used as a potential adjuvant for EV-A71 and EV-D68 bivalent mucosal vaccines. Our results provide useful information for the further preclinical and clinical development of a mucosal bivalent enterovirus vaccine against both EV-A71 and EV-D68 infections.

Abstract
Objective: To analyze the clinical characteristics of patients with severe immune checkpoint inhibitors (ICIs) related myocarditis. Methods: A retrospective study was conducted on the 50 patients with ICIs-related myocarditis in the multidisciplinary cardio-oncology clinic of Zhongshan Hospital affiliated to Fudan University from April 2020 to April 2022. The age of patients was (63.7±10.8) years old, including 37 males and 13 females. The patients were divided into the mild group (n=37) and the severe group (n=13) according to severity. The differences of basic characteristics, clinical manifestations, laboratory tests, auxiliary examination, combined irAEs, treatment and outcomes between the two groups of patients were analyzed. Results: The immunotherapy time [M(Q1,Q3)] of patients in the mild group and severe group were 81 (49, 134) and 24 (20, 116) days, respectively (P<0.05). In the severe group, the levels of cTnT [0.605 (0.317, 1.072) μg/L], NT-proBNP [1 126 (386, 1 744) ng/L], CK-MB [78 (48, 238) U/L], and CK-MM [240 (45, 6 543) U/L] were higher than those in the mild group [0.104 (0.045, 0.189) μg/L, 237 (39, 785) ng/L, 24 (20, 33) U/L, 108 (72, 168) U/L, respectively] (all P<0.05). The left ventricular ejection fraction of the severe group [64% (57%, 65%)] was lower than that of the mild group [66% (63%, 69%)] (P<0.05), and the incidence of conduction block (n=4, 4/13) and abnormal ventricular wall motion (n=4, 4/13), the incidence of ICIs-related myositis (n=10, 10/13), ICIs-related hepatitis (n=4, 4/13) and ICIs-related neurotoxicity (n=4, 4/13) were higher than those in the mild group (n=1, 2.7%; n=2, 5.4%; n=16, 43.2%; n=2, 5.4%; n=1, 2.7%, respectively) (all P<0.05). The proportion of patients receiving intensified immunosuppressive therapy and mortality rate in the severe group were 12/13 (n=12) and 4/13 (n=4), which were both higher than those in the mild group [10.8% (n=4) and 0] (both P<0.05). Conclusions: The incidence of ICIs-related myocarditis is not high, but the severe rate and mortality are high. The differential diagnosis of severe ICIs related myocarditis should be combined with myocardial markers, electrocardiogram and echocardiogram, and early diagnosis and treatment can improve the prognosis of patients.

Abstract
Objective: To investigate the clinical pathological characteristics of ocular adnexal follicular lymphoma (OAFL). Methods: A retrospective case series study was conducted. Clinical data of 10 OAFL patients diagnosed at Tianjin Eye Hospital from January 1990 to May 2022 were collected. The study analyzed general patient information, medical history, site of involvement, imaging, histopathology, and molecular detection. Among them, 7 cases underwent Epstein-Barr virus-encoded small RNA (EBER) and B-cell lymphoma protein 2 (BCL-2)/immunoglobulin heavy chain gene (IgH) translocation gene detection. Treatment and prognosis of patients were followed up. Results: All 10 patients (10 eyes) had unilateral involvement, including 5 males and 5 females, with an age range of 58 (43, 68) years. Clinical manifestations included eyelid swelling, pink conjunctival thickening, painless slow-growing masses in the lacrimal gland area, extraconal muscle cone, conjunctiva, lacrimal sac, or a combination of lacrimal sac and conjunctiva. Among them, 8 cases were primary, and 2 cases were secondary. According to the Ann Arbor staging, 8 cases were stage Ⅰ-Ⅱ E, and 2 cases were stage Ⅲ E. Histopathological grading revealed 6 cases of grade 1-2 and 3 cases of grade 3A. One case showed grade 3B in the lacrimal sac area and grade 1-2 in the conjunctiva. The predominant subtype was follicular in 4 cases, diffuse in 3 cases, and mixed in 2 cases. One case had a mixed subtype involving the lacrimal sac and conjunctiva. All patients expressed positivity for leukocyte differentiation antigens (CD) 20, CD21, and CD23. Nine cases were positive for CD10, with 1 case showing partial CD10 positivity. All patients were positive for B-cell lymphoma protein 6 (BCL-6), and 9 cases were positive for BCL-2. Specific markers CyclinD1 and Multiple Myeloma Oncogene Protein 1 (MUM-1) were negatively expressed in all cases. The Ki-67 proliferation index ranged from 10% to 90%. Molecular detection was performed in 7 patients, with none showing positive EBER in situ hybridization. However, 5 cases exhibited BCL2/IgH gene fusion. Among 7 patients with follow-up data, the median follow-up time was 17 (6, 34) months. Four patients achieved complete remission, 2 had partial remission, and 1 patient died due to lung infection. Conclusions: OAFL is a tumor originating from follicular center B-cells, characterized by positive expression of BCL-2, CD10, and BCL-6. It can involve the lacrimal gland, extraconal muscles, lacrimal sac, and conjunctiva. Patients generally have a favorable prognosis.

Abstract
PURPOSE/OBJECTIVE(S) In recent years, there has been a decline in the number of radiation oncology residency applicants. New techniques to recruit students to the field are necessary. Early exposure to oncology care in pre-clinical years may translate to increased student interest in oncology-related fields and improved understanding of oncologic treatment modalities. We propose that a cancer-specific problem-based learning (PBL) case will increase exposure to oncology during pre-clinical years. MATERIALS/METHODS A PBL case regarding pancreatic cancer was created by a radiation oncology resident/faculty member and the gastrointestinal course director for first-year medical students (n = 140) at a single institution. The one-hour small group case focused on oncologic work up, multi-disciplinary care and radiotherapy concepts. Students were provided with a case prompt and resources to review prior to the PBL session. Volunteer radiation oncology facilitators then guided students through the case to achieve desired learning objectives. Following the PBL, students completed an optional nine-question survey regarding their experience. RESULTS A total of 76 (54%) medical students completed the post-PBL survey. The majority (89%) of students reported that the case motivated them to learn more about oncology, and almost all (99%) noted improved understanding of the multidisciplinary nature of cancer care. 75 (99%) students reported increased understanding of how radiotherapy is delivered. 62 (82%) students reported increased motivation to learn about radiation oncology. 38 (50%) students reported that they plan to participate in an elective in oncology. 36 (47%) reported that they are considering pursuing an oncologic field. There was an increase in the number of subscribers to the Oncology Interest Group (43% increase from previous year) and positive feedback was noted from free-text responses from participants. CONCLUSION Integrating a cancer-specific PBL case facilitated by radiation oncology educators into the pre-clinical curriculum is an effective avenue to introduce oncology concepts and stimulate interest in oncology amongst first-year medical students.

Abstract
Objective: To analyze the clinical and pathological characteristics and prognosis of 35 cases of solitary fibrous tumor of ocular adnexal (SFT). Methods: This was a retrospective case series study. The clinical data of 35 cases of ocular adnexal SFT was collected in Tianjin Eye Hospital from January 2000 to December 2020. The clinical manifestations, imaging examination results, pathological characteristics, treatment of patients were analyzed, and patients were followed up. All cases were classified according to the 2013 classification of World Health Organization of tumors of soft tissue and bone. Results: There were 21 males (60.0%) and 14 females (40.0%). The age range was 17 to 83 years, and the median age was 44 (35, 54)years. All patients were unilateral, with 23 (65.7%) in the right eye and 12 (34.3%) in the left eye. The course of disease ranged from 2 months to 11 years, with an a median duration of 12(6,36)months. Clinical manifestations included exophthalmos, limited eye movements, diplopia, and tearing. All patients underwent surgical treatment of complete resection of the tumor. Ocular adnexal SFT mostly occurred in the upper orbit (19 cases, 73.1%). On imaging examination, the tumor showed well-circumscribed space occupying lesion that heterogeneously enhanced with contrast, and abundant blood flow signals in the tumors. MRI showed isointensity or low signal on T1WI, and significantly enhanced on T2WI, presenting intermediate-to-high heterogeneous signals. The tumor diameter was 2.1 (1.5, 2.6) cm. There were 23 cases (65.7%) of classic subtype, 2 cases (5.7%) of giant cell subtype, 8 cases (22.9%) of myxoid subtype, and 2 cases (5.7%) of malignancy. Immunohistochemical staining showed that Vimentin, CD34 and STAT6 were positively expressed in all patients. Twenty-one cases (60.0%) showed positive expression of BCL-2, and Ki-67 positive index ranged from 1.0% to 10.0%. Tumors in this group were all low-risk according to the Demicco risk stratification. Follow-up was available for 25 patients with a duration of 2 years to 14 years and 7 months, and the median follow-up time was 88 (61, 124) months. Two patients relapsed, and no distant metastasis or death was observed. Conclusions: Ocular adnexal SFT mainly presents as a painless, slow-growing mass. And most of them are typical SFT. The imaging manifestations are varied Ocular adnexal SFT generally follows a benign course, with a good prognosis after complete excision. Recurrence could occur many years after surgery which requiring careful and long-term follow-up.

Abstract
BACKGROUND The establishment of laws has had a tremendous impact on holistic medical care. The Patient Right to Autonomy (PRA) Act and the Same-Sex Marriage Act have been passed in Taiwan, and both have sparked intense societal debate. The Same-Sex Marriage Act and PRA Act (SMPRA) teaching module was created for the Gender, Medicine, and Law (GML) course of the medical curriculum. This video trigger-assisted problem-based learning (VTA-PBL) software has integrated content on the aforementioned legislative proclamations. It upends conventional beliefs and fosters reflective practices on sexual rights and the right to representation among medical students. This study examined how the SMPRA module affected the knowledge and attitudes of medical students taking up the GML course. METHODS A simple pre-/post-test design evaluated the outcomes of the PBL module to examine the changes in knowledge and attitudes of medical students toward same-sex marriage rights. In 2019 and 2020, 126 and 49 5th-year medical students took up the GML course, respectively. The GML components included a video scenario representing advanced decision-making and a healthcare agency with a same-sex couple, a PBL discussion, and student feedback presentations. The mechanisms of feedback collection and measuring student knowledge and attitudes toward sexual rights differed between one cohort in 2019 and the other in 2020. Pre- and post-lecture tests were used in the first school year, whereas a post-lecture open-ended questionnaire survey was used in the second school year. RESULTS In total, 90 and 39 eligible questionnaires were received in the first and second school years, respectively, which corresponded to response rates of 71% and 80%. Students showed a better understanding of and positive enhancement of proficiency in legal and ethical content and relevant clinical practice. Qualitative analysis revealed that students viewed healthcare providers as checkpoints for conflicts of interest; medical ethics as the cornerstone of clinical practice; cultural background as a significant influence on decision-making; and empathetic communication as the cornerstone of relationships between patients, family members, and doctors. CONCLUSION The GML course of the SMPRA module fosters reflective practices on ethical and legal sexual rights issues.

Abstract
To determine phenotype-related dupilumab response in adult patients with atopic dermatitis (AD), this multicenter, retrospective study included 111 adults with moderate-to-severe AD in Taiwan, with median age of 31.5 years (18–87) and 71 (64.0%) males. Patients received dupilumab 300 mg per two to three weeks up to 12 months. We found a significant improvement after 4 and 16 weeks of treatment in all patients for all the assessed scores, including eczema area and severity index (EASI) improvement ≥50% (EASI-50) and 75% (EASI-75), EASI reaching minimal clinically important difference (MCID), and Investigator’s Global Assessment (IGA) improvement ≥2. Importantly, prior to asthma, early AD onset and 3-week drug intervals were significantly associated with a high proportion of EASI-75 at month 12, while prurigo and lichenoid phenotypes were associated with a lower proportion of EASI-75 at month 12. However, the majority of adverse events were mild in severity. In conclusion, our study results identify phenotype-related dupilumab response at month 12 in adults with moderate-to-severe AD, and we suggest that treatment should not be discontinued until reaching a satisfactory clinical response.

Abstract
Objective: To investigate the clinicopathological features of adult orbital xanthogranulomatous disease (AOXGD) with lacrimal gland reactive lymphoid hyperplasia. Methods: Retrospective case series study. The clinical and pathological data of AOXGD cases diagnosed and treated in Tianjin Eye Hospital from January 2002 to December 2021 was reviewed, and the clinical characteristics, radiologic findings and pathological characteristics of periocular and lacrimal gland lesions of 5 cases were retrospectively analyzed. The expression of IgG4 and IgG protein in periocular and lacrimal gland lesions was detected by immunohistochemical staining, and the role of IgG4 in AOXGD was preliminarily studied. Results: There were four females and one male with an average age of 53.8 years (39 to 77 years). Among the five AOXGD cases, there were three cases of adult-onset xanthogranuloma, one case of adult-onset asthma and periocular xanthogranuloma, and one case of necrobiotic xanthogranuloma. All cases involved both eyes. The swelling of eyelids was observed in five cases, and the yellow or pale yellow eyelid skin was found in two cases. Imaging examinations showed the tumor mainly involved the eyelids, subcutaneous tissues, anterior orbit and lacrimal gland. A large number of foam cells and typical Touton giant cells were found in the periorbital lesions, accompanied by different degrees of fibrosis. The fibrinoid necrosis was detected in one case of necrobiotic xanthogranuloma. The lacrimal gland lesions showed different types of reactive lymphoid hyperplasia, including IgG4-related disease in two cases, follicular lymphoid hyperplasia in two cases and focal lymphoid hyperplasia in one case. IgG4 levels of periorbital and lacrimal gland lesions were elevated in four cases. Asthma and elevated serum IgG4 were found in one case of adult-onset periocular xanthogranuloma. Three patients underwent surgical resection and adjuvant hormone or immunosuppressive therapy, and two patients underwent simple surgical resection. The patients were followed up for 1.5 to 10.0 years, one patient was lost, and four patients had no recurrence. Conclusions: AOXGD with lacrimal gland reactive lymphoid hyperplasia is a group of rare diseases. The periorbital lesions of that are characterized by proliferation of foamy histiocytes and Touton giant cells, and the lacrimal gland lesions of that manifest as IgG4-related disease in some cases.

Abstract
Psoriatic arthritis is a chronic systemic autoimmune disease, characterized by psoriasis skin lesions and inflammation of the spine and joint. It has complicated clinical manifestations and individual variations. Nearly half of the patients will have joints erosion in two years, which is crippling. The severity of the skin and joint disease frequently do not correlate with each other. Currently, the understanding of the disease is insufficient in China with the lack of standardized diagnosis and treatment. Therefore, researchers from the Chinese Rheumatology Association formulated this specification based on the diagnosis and management experience together with guidelines at home and abroad. The specification summarizes the present situation of domestic diagnosis and treatment, aiming to standardize the diagnosis process and treatment protocols of psoriatic arthritis. Furthermore, it can reduce misdiagnosis and missed diagnosis, as well as improve the prognosis.

Abstract
The reproductive function of animals is often affected by climatic conditions. High-temperature conditions can cause damage to oocyte maturation and embryonic development in a variety of ways. The purpose of this study was to prove that supplementation idebenone (IDB) to the maturation medium can improve the maturation and development of porcine oocytes after heat stress (HS). Porcine cumulus-oocyte complexes (COCs) were cultured in the maturation medium with different concentrations of IDB (0, 0.1, 1 and 10 μM) for 44 hr at either 38.5°C or under the HS conditions. The cumulus oophorus expansion, nuclear maturation and blastocyst rate after parthenogenetic activation (PA) were measured. We found that HS (in vitro maturation 20-24 hr, 42°C) exposure significantly reduced cumulus expansion index and maturation rate of oocytes and the blastocyst rate of PA embryos, while IDB supplementation significantly improved oocyte maturation and development to the blastocysts stage after PA. Moreover, the addition of IDB decreased the intracellular level of ROS and increased GSH content, hence enhancing the antioxidant capacity of oocytes under HS. Meanwhile, IDB treatment also obviously improved the mitochondrial membrane potential and ATP synthesis of oocytes under HS conditions. Furthermore, IDB treatment increased the expression of GDF9 and BMP15 in IVM oocytes which attribute to improve the quality and outcome of IVM oocytes and the development competence of PA embryos in pigs. In summary, we demonstrated that IDB supplementation into the maturation medium exerted protective effects and improved the ability of maturation and developmental competence of porcine oocytes exposed to HS.

Abstract
The West Philippine Basin (WPB) has started opening at ~ 58 Ma and ceased spreading at ~ 33 Ma, developing a fast spreading (~ 44 mm/yr half-spreading rate) magmatic episode between 58 and 41 Ma and the second amagmatic episode between 41 and 33 Ma. The occurrence of the first stage of spreading is closely related to the Oki-Daito mantle plume and related Benham Rise (BR) and Urdaneta Plateau (UP) activity. To the east of the Luzon–Okinawa Fracture Zone (LOFZ), BR was the most active volcanism from 48 to 41 Ma. The geomagnetic ages on both sides of the LOFZ have been determined; however, their causal relationship and evolution in the WPB remain unclear. In this study, we performed integrated analyses of multichannel seismic data and swath bathymetry data for the area to the west of the LOFZ. To the west of the LOFZ, the Gagua Rise (GR), is identified by a high residual free-air gravity anomaly, volcanic seamount chains and an overlapping spreading center. The GR is located at magnetic isochrons C20/C22 (50 to 44 Ma) and shows a thick oceanic crust of at least 12.7 km. We first propose an oceanic plateau named Great Benham Rise (GBR) which includes GR, UP and BR. We infer that the GR was a portion of the GBR since ~ 49 Ma and was separated from the GBR at ~ 41 Ma by the right-lateral LOFZ motion. Later, the relict GBR magmatism only continued in the area to the east of the LOFZ. Overall, the GBR dominates the spreading history of the WPB.

Abstract
Enterovirus A71 (EV-A71) and many members of the Picornaviridae family are neurotropic pathogens of global concern. These viruses are primarily transmitted through the fecal-oral route, and thus suitable animal models of oral infection are needed to investigate viral pathogenesis. An animal model of oral infection was developed using transgenic mice expressing human SCARB2 (hSCARB2 Tg), murine-adapted EV-A71/MP4 virus, and EV-A71/MP4 virus with an engineered nanoluciferase gene that allows imaging of viral replication and spread in infected mice. Next-generation sequencing of EV-A71 genomes in the tissues and organs of infected mice was also performed. Oral inoculation of EV-A71/MP4 or nanoluciferase-carrying MP4 virus stably induced neurological symptoms and death in infected 21-day-old weaned mice. In vivo bioluminescence imaging of infected mice and tissue immunostaining of viral antigens indicated that orally inoculated virus can spread to the central nervous system (CNS) and other tissues. Next-generating sequencing further identified diverse mutations in viral genomes that can potentially contribute to viral pathogenesis. This study presents an EV-A71 oral infection murine model that efficiently infects weaned mice and allows tracking of viral spread, features that can facilitate research into viral pathogenesis and neuroinvasion via the natural route of infection. IMPORTANCE Enterovirus A71 (EV-A71), a positive-strand RNA virus of the Picornaviridae, poses a persistent global public health problem. EV-A71 is primarily transmitted through the fecal-oral route, and thus suitable animal models of oral infection are needed to investigate viral pathogenesis. We present an animal model of EV-A71 infection that enables the natural route of oral infection in weaned and nonimmunocompromised 21-day-old hSCARB2 transgenic mice. Our results demonstrate that severe disease and death could be stably induced, and viral invasion of the CNS could be replicated in this model, similar to severe real-world EV-A71 infections. We also developed a nanoluciferase-containing EV-A71 virus that can be used with this animal model to track viral spread after oral infection in real time. Such a model offers several advantages over existing animal models and can facilitate future research into viral spread, tissue tropism, and viral pathogenesis, all pressing issues that remain unaddressed for EV-A71 infections.

Abstract
BACKGROUND Imiquimod cream may be used as a non-surgical treatment for lentigo maligna or as adjuvant therapy following excision to decrease the risk of recurrence. OBJECTIVES To evaluate histologic and clinical factors associated with clinical clearance of lentigo maligna treated with imiquimod. METHODS We performed a retrospective review of all patients diagnosed with lentigo maligna and treated with imiquimod between 1997 and 2019 at our academic institution. RESULTS We observed clinical clearance in 93% (66/71) of participants who received adjuvant imiquimod following surgery and 79% (19/24) in the primary non-surgical treatment group over a median of 38 months of follow-up. In the adjuvant therapy group, positive surgical margins were associated with a decreased rate of clinical clearance when compared to cases with close (<1 mm) margins or background melanocytic dysplasia (83.3 vs. 100%, p = .01). The presence of an inflammatory response during treatment was associated with increased clearance (94.1 vs. 66.7%, p = .02). CONCLUSIONS Adjuvant imiquimod treatment may decrease LM recurrence rates in cases with background melanocytic dysplasia or close margins. LM cases with positive surgical margins need close clinical follow-up given higher recurrence rates.

Abstract
Objective: To summarize the clinical and pathological characteristics of diffuse large B-cell lymphoma of ocular adnexal (OA-DLBCL). Methods: A retrospective case series study. Twenty-three cases of OA-DLBCL were collected in Tianjin Eye Hospital from January 2005 to December 2018. The clinical manifestations and imaging examination results were analyzed. The pathological characteristics and immune subtypes were analyzed with hematoxylin and eosin staining and immunohistochemistry. Eighteen patients completed the follow-up. Overall survival (OS) time was from the date of diagnosis to the date of death or the final follow-up (April 30, 2020). Clinical stages were analyzed by the Ann Arbor classification; Kaplan-Meier plots were used to visualize survival outcomes. The different risk groups were compared using Log-rank test. Results: There were 13 males and 10 females. The median age was 65 years (range, 43 to 82 years). Twenty-two patients had unilateral lymphoma (14 left eyes, 8 right eyes), and one patient had bilateral lymphoma. The OA-DLBCL was in the orbit in 14 patients, in the lacrimal gland in two patients, in both the lacrimal gland and the orbit in three patients, in both the lacrimal sac and the orbit in one patient, in the conjunctiva in one patient, in both the conjunctiva and the orbit in one patient, and in the skin of eyelids in one patient. Imaging examinations showed the tumors were of irregular soft tissue density. MRI showed the tumors were close to the extraocular muscles or ectocinerea. Centroblastic morphology was present in 21 specimens, and 2 specimens had immunoblastic morphology. Six patients were of germinal center B cell-like (GCB) type, and 17 were of non-GCB type. There were 2 patients with double expression of cellular-myelocytomatosis viral oncogene and B-cell lymphoma 2. The follow-up time ranged from 25 to 156 months, and the median follow-up time was 48 months. Five of them had primary OA-DLBCL, and 13 patients had secondary OA-DLBCL. Five patients were at the Ann Arbor clinical stage ⅠE, one was at stage ⅢE, and 12 were at stage ⅣE. During the follow-up, 8 patients survived, and 10 died. The 1-, 3-, and 5-year OS rates were 88.9%, 71.4% and 41.7%, respectively. Log-rank analysis indicated that the Ann Arbor clinical stage and age were related to the OS of OA-DLBCL (χ²=7.448, 8.804; both P<0.01). The gender, tumor size, molecular typing, Ki-67 index, and bone invasion were not related to the OS of OA-DLBCL (all P>0.05). Conclusions: OA-DLBCL mainly occurrs in the elderly population, unilaterally, and in the orbit. Most molecular types are non-GCB subtypes. The Ann Arbor clinical stage and age are associated with prognosis. (Chin J Ophthalmol, 2021, 57: 366-371).

Abstract
Lignosus rhinocerotis (Tiger's Milk mushroom) is a novel mushroom with sclerotium belonging to the Polyporaceae family and has been reported widely to possess anti-cancer, anti-cough, antioxidant, gastro-protective, immuno-modulating, and neurite-stimulating properties. As numerous studies have proven the tremendous medicinal values of L. rhinocerotis, it is necessary to understand its nutrition as well as its safety for the recipient. Previous research on L. rhinocerotis has mainly focused on the naturally occurring sclerotium and may have overlooked mushroom mycelia from submerged liquid fermentation, which ensures a high uniform quantitative biomass production as well as a high biological value. Hence, this is the first report on the evaluation of nutrition and 13-week repeated oral toxicity of L. rhinocerotis mycelium (LRM). The LRM powder contained 9.0 ± 4.2% moisture, 1.9 ± 1.3% ash, 1.6 ± 2.2% crude lipid, 8.4 ± 5.3% crude protein, 79.3 ± 4.6% carbohydrate, and 364 kcal/100 g energy. The total free amino acid ranged from 349 to 5636 mg/100 g and the umami index of freeze-dried LRM powder was 0.37. For safety assessment, ninety-six rats were divided into four groups, each consisting of twelve male and twelve female rats. Test articles were administered by oral gavage to rats at 850, 1700, and 3400 mg/kg body weight/day for 13 weeks and reverse osmosis water was used as the control. All animals survived to the end of the study. During the experiment period, no abnormal changes were observed in clinical signs, body weight, or ophthalmological examinations. No adverse or test article-related differences were found in urinalysis, hematology, or serum biochemistry parameters between the treatment and control groups. Necropsy and histopathological examination indicated no treatment-related changes. According to the above results, the no-observed-adverse-effect level (NOAEL) of L. rhinocerotis was identified to be greater than 3400 mg/kg body weight (BW)/day in Sprague-Dawley rats.

Abstract
BACKGROUND Bullous skin disorders are induced by different pathomechanisms and several are emergent, including Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). Rapid diagnostic methods for SJS/TEN or cytotoxic T-lymphocyte (CTL)-mediated bullous disorders are crucial for early treatment. Granulysin, primarily expressed by CTLs, is a specific cytotoxic protein responsible for SJS/TEN and similar skin reactions. OBJECTIVE To assess granulysin levels in blister fluids to differentiate SJS/TEN and similar CTL-mediated bullous reactions from other autoimmune bullous disorders. METHODS Using ELISA, we measured granulysin in blister fluids from patients with bullous skin disorders, including SJS/TEN, erythema multiforme major, bullous fixed-drug eruption, bullous lupus erythematosus, paraneoplastic pemphigus, pemphigus vulgaris, bullous pemphigoid, purpura fulminans-related bullae, and hand-foot syndrome/hand-foot-skin reactions. We compared serum and blister granulysin levels in patients with SJS/TEN presenting varying severity, monitoring serial granulysin levels from acute to late stages. RESULTS Overall, 144 patients presenting with bullous skin disorders were enrolled. Blister granulysin levels (mean ± SD) in CTL-mediated disorders, including TEN (n = 28; 3938.7 ± 3475.7), SJS-TEN overlapping (n = 22; 1440.4 ± 1179.6), SJS (n = 14; 542.0 ± 503.2), erythema multiforme major (n = 7; 766.3 ± 1073.7), generalized bullous fixed-drug eruption (n = 10; 720.4 ± 858.3), and localized bullous fixed-drug eruption (n = 16; 69.0 ± 56.4), were significantly higher than in non-CTL-mediated bullous disorders (P < .0001), including bullous lupus erythematosus (n = 3; 22.7 ± 20.1), paraneoplastic pemphigus (n = 3; 20.3 ± 8.6), pemphigus vulgaris (n = 3; 4.4 ± 2.8), bullous pemphigoid (n = 18; 4.0 ± 2.7), purpura fulminans (n = 4; 5.9 ± 5.5), and hand-foot syndrome/hand-foot-skin reactions (n = 6; 4.6 ± 3.5). Blister granulysin levels correlated with clinical severity of SJS/TEN (P < .0001). CONCLUSIONS Determination of blister granulysin levels is a noninvasive and useful tool for rapid differential diagnosis of SJS/TEN and other similar CTL-mediated bullous skin disorders for treatment selection.

Abstract
BACKGROUND Patients with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) have high mortality rates. Disseminated intravascular coagulation has been reported in SJS/TEN patients. The influence of this lethal complication in patients with SJS/TEN is not well known. OBJECTIVE This study aimed to investigate the risk and outcomes of disseminated intravascular coagulation in patients with SJS/TEN. METHODS We analyzed the disseminated intravascular coagulation profiles of patients receiving a diagnosis of SJS/TEN between 2010 and 2019. RESULTS We analyzed 150 patients with SJS/TEN (75 with SJS, 22 with overlapping SJS/TEN, and 53 with TEN) and their complete disseminated intravascular coagulation profiles. Disseminated intravascular coagulation was diagnosed in 32 patients (21.3%), primarily those with TEN. It was significantly associated with systemic complications, including gastrointestinal bleeding, respiratory failure, renal failure, liver failure, infection, and bacteremia. Additionally, SJS/TEN patients with disseminated intravascular coagulation had elevated procalcitonin levels. Among patients with SJS/TEN, disseminated intravascular coagulation was associated with a greater than 10-fold increase in mortality (78.1% vs 7%). LIMITATIONS The study limitations include small sample size and a single hospital system. CONCLUSION Disseminated intravascular coagulation is a potential complication of SJS/TEN and associated with higher mortality. Early recognition and appropriate management of this critical complication are important for patients with SJS/TEN.

Abstract
Objective: To analyze the pathological classification and age distribution of primary neoplasms of the lacrimal drainage system. Methods: Retrospective case series study. A total of 64 patients (65 eyes) were diagnosed with primary neoplasms of the lacrimal drainage system and received surgery at Tianjin Eye Hospital from January 2006 to December 2016. All the clinical data of the patients were analyzed, including gender, diseased eye, age, clinical manifestations, composition of benign and malignant masses, and prognosis. The histopathological composition and age distribution of patients with primary lacrimal mass, lacrimal duct mass and lacrimal sac mass were analyzed according to the different diseased sites. Results: Twenty-three patients (24 eyes) were male, and 41 patients (41 eyes) were female. The right eye was involved in 36 patients, the left eye in 27 patients, and both eyes in one patient. The age at diagnosis ranged from 12 to 78 years old [mean, (46±4) years]. The course of disease was (13.1±4.2) months, ranging from 1 month to 7 years. The chief complaint was tear discharge in 43 patients, tumor in 19 patients, and abscess discharge in 2 patients. There were 29 patients with angular displacement and 21 patients with swelling pain. There were 51 patients with benign lesions, 4 with borderline lesions, and 9 with malignantlesions. These neoplasms consisted of primary peripunctal neoplasms in 17 patients, primary canalicular neoplasms in 2 patients, and primary lacrimal sac neoplasms in 45 patients. All primary peripunctal neoplasms (17 cases) were benign, among which nevi (10 cases) occupied the first place. All primary canalicular neoplasms (2 cases) were benign, there were 1 case of epidermoid cysts and 1 case of degenerative disease. Among the primary benign lacrimal sac masses (32 cases), mucous epithelial cysts (9 cases), dermoid cysts (6 cases), and epidermoid cysts (6 cases) occupied the first three places. Among the primary borderlin lacrimal sac masses (4 cases), there were 2 cases of giant cell tumor of soft tissue, 1 case of solitary fibrous tumor, and 1 case of inflammatory myofibroblastic tumor. The primary malignant mass of lacrimal sac (9 cases) was dominated by squamous cell carcinoma (3 cases). In terms of age distribution, the patients with primary peripunctal mass were mainly in the group of 40-59 years old (14 cases). The primary benign mass of lacrimal sac mainly occurred in the group of less than 40 years old (15 cases) and the group of 40-59 years old (11 cases). The patients with primary lacrimal sac borderline and malignant masses were all in the groups of over 40 years old. A total of 49 patients were followed up for 27 months to 16 years. The average follow-up time was (57.2±3.8) months. Lacrimal sac transitional cell carcinoma relapsed 7 months after surgery in one patient, and lacrimal sac melanoma relapsed 1 year after surgery in one patient. The patients did not relapse in 24 months and 38 months after surgery respectively. There were no recurrence of other cases. Conclusions: Primary peripunctal neoplasms are mostly characterized with benign lesions, among which nevi are most common. Mucous epithelial cysts, epidermoid cysts, and dermoid cysts are the major benign lacrimal sac neoplasms. Squamous cell carcinomas are the most common malignant lacrimal sac neoplasms. The malignant tumor of lacrimal sac often occurs in the middle-aged and elderly patients. (Chin J Ophthalmol, 2020, 56: 364-369).

Abstract
We study the transport of surface electrons on superfluid helium through a microchannel structure in which the charge flow splits into two branches, one flowing straight and one turned at 90°. According to Ohm's law, an equal number of charges should flow into each branch. However, when the electrons are dressed by surface excitations (ripplons) to form polaronlike particles with sufficiently large effective mass, all the charge follows the straight path due to momentum conservation. This surface-wave induced transport is analogous to the motion of electrons coupled to surface acoustic waves in semiconductor 2DEGs.

Abstract
Epicutaneous (EC) sensitization with protein allergens is the most important sensitization route for atopic dermatitis. Plasmacytoid dendritic cells (pDCs) are characterized by massive secretion of interferon-α (IFNα). B6 mice are T helper type 1 (Th1)-prone and are representative of non-atopic humans, whereas BALB/c mice are Th2-prone and are representative of atopic humans. Here, we show that naïve BALB/c mice contain a greater number of nonactivated pDCs in peripheral lymph nodes (LNs) than do naïve B6 mice. Naïve BALB/c mice also have more of the CD8α- subset in LNs than naïve B6 mice. Moreover, in vivo depletion of pDCs during EC sensitization results in enhanced Th2 responses in BALB/c mice, but not in B6 mice. Mechanistically, when BALB/c mice undergo EC sensitization, there is an increase in pDCs entering draining LNs. These cells exhibit modest activation including comparable costimulation expression but increased cytokine expression compared with those of naïve mice. In vivo depletion of pDCs during EC sensitization significantly increases the activation of dermal dendritic cells (dDCs) suggesting a regulatory effect on these cells. To this end, a suppressive effect of pDCs on conventional dendritic cells was also demonstrated in vitro. Further, in vivo blockade of IFNα by an anti-IFNAR antibody (Ab) or in vivo reduction of IFNα production of pDCs by anti-siglec-H Ab both resulted in enhanced activation of dDCs. Collectively, our results demonstrate that pDCs suppress Th2 responses induced by EC sensitization via IFNα-mediated regulation of dDCs.

Abstract
The anti-tumor activity of diosgenin, a new steroidal constituent present in fenugreek, on two human breast cancer cell lines, MCF-7 and Hs578T, was studied. Diosgenin treatment resulted in cell growth inhibition, cell cycle arrest, and apoptosis in concentration- and time-dependent manners in both cell lines. Western blot analyses of whole cell lysates for cell cycle proteins showed that diosgenin altered phosphorylated cyclin checkpoint1 (p-Chk1Ser345) and cyclin B expression, which resulted in G2/M phase blockade. Mechanistically, Cdc25C-Cdc2 signaling was involved in inactivating Chk1Ser345 by p53-dependence in MCF-7 cells and p21-dependence in Hs578T cells that are p53-deficient. Moreover, diosgenin induced a significant loss of the mitochondrial membrane potential in breast cancer cells, and prominently affected cell death through down-regulation of the anti-apoptotic protein, Bcl-2. This released cytochrome c and activated the caspase signaling cascade. Taken together, these findings reveal that the anti-proliferative activity of diosgenin involves the induction of G2/M phase arrest via modulating the Cdc25C-Cdc2-cyclin B pathway and mitochondria-mediated apoptosis in human breast cancer cell lines. This suggests the potential usefulness of diosgenin in treating breast cancer.

Abstract
Objective: To summarize the clinical and pathological characteristics of IgG4-related ophthalmic disease (IgG4-ROD) involving the lacrimal gland. Methods: A retrospective case series study. Forty cases (56 eyes) of lacrimal gland lesions were collected in Tianjin Eye Hospital from January 2003 to January 2018 and confirmed by histopathology as lymphocyte and plasma cell infiltration with fibrosis of lacrimal gland tissue, excluding lymphoma, epithelial tumor, mesenchymal tumor and metastasis tumor. The clinical manifestations, serological and imaging examination of the patients were analyzed. Meanwhile, HE staining and immunohistochemical staining of IgG and IgG4 were performed on the pathological specimens. According to the diagnostic criteria, the cases were divided into the IgG4-ROD group and the non-IgG4-ROD group. The clinical and pathological characteristics of the two groups were statistically analyzed by Pearson chi-square and signed-rank test. Results: In the 40 cases (56 eyes), there were 15 cases (25 eyes) of IgG4-ROD and 25 cases (31 eyes) of non-IgG4-ROD. Statistically significant differences were observed between the two groups in the clinical and pathological characteristics (all P<0.05). About the distribution of eyes position, there were 10 binocular cases and 5 monocular cases in the IgG4-ROD group, and 6 binocular cases and 19 monocular cases in non-IgG4-ROD group (χ2=7.111).There were 21 eyes in the IgG4-ROD group and 5 eyes in the non-IgG4-ROD group about ptosis (χ2=25.631), 4 eyes in the IgG4-ROD group and 21 eyes in the non-IgG4-ROD group about ocular protrusion (χ2=14.992), 23 eyes in the IgG4-ROD group and 15 eyes in the non-IgG4-ROD group about the clear boundary of the tumor (χ2=12.069), 4 eyes in the IgG4-ROD group and 18 eyes in the non-IgG4-ROD group about the involvement of other orbital tissues (χ2=10.266) and 7 cases in the IgG4-ROD group and 3 cases in the non-IgG4-ROD group about the association with other systemic diseases (χ2=6.009). Compared with the non-IgG4-ROD group, the IgG4-ROD group had a heavier lymphocyte and plasma cell infiltration (+++,++,+; 10, 4, 1 vs. 6, 5, 12 eyes, Z=-3.153), and more lymphoid follicles (+++,++,+; 3, 6, 4 vs. 1, 2, 7 eyes, Z=-3.339), interstitial fibrosis was mostly striate (10 vs. 5 eyes, χ2=8.711), and there were a large number of IgG4+ plasma cells [96 (67, 135) vs. 4 (0, 12) cells per high power field, Z=-5.271] and ratio of IgG4+ plasma cells/IgG+ plasma cells [0.570 (0.500, 0.754) vs. 0.046 (0.000, 0.143), Z=-5.268, all P<0.05). Among the 10 cases of IgG4-ROD with serological examination, 9 cases showed elevated serum in IgG and IgG4. The ultrasonography and CT findings showed the lacrimal gland lesions in the IgG4-ROD group were mostly spindle or kidney shaped with clear boundaries, while the lesions in non-IgG4-ROD were mostly round or irregular with unclear boundaries. Conclusions: The lacrimal gland lesions of IgG4-ROD are characterized by bilaterally spindle or kidney shaped enlargement with clear boundaries. They are more associates with other systemic diseases. The pathological characteristics are a large number of IgG4+ plasma cells infiltration among the lacrimal gland tissue, interstitial striate fibrosis and a large number of lymphoid follicles.

Abstract
Enterovirus 71 (EV71) induces apoptosis to promote viral particle release. Earlier work showed that EV71 utilizes its 3C protease to induce apoptosis in a caspase-3-dependent pathway, though the mechanism is unknown. However, work from Vagner, Holcik and colleagues showed that host protein heterogeneous ribonucleoprotein A1 (hnRNP A1) binds the IRES of cellular apoptotic peptidase activating factor 1 (apaf-1) mRNA to repress its translation. In this work, we show that apaf-1 expression is essential for EV71-induced apoptosis. EV71 infection or ectopic expression of 3C protease cleaves hnRNP A1, which abolishes its binding to the apaf-1 IRES. This allows IRES-dependent synthesis of apaf-1, activation of caspase-3, and apoptosis. Thus, we reveal a novel mechanism that EV71 utilizes for virus release via a 3C protease-hnRNP A1-apaf-1-caspase-3-apoptosis axis.

Abstract
Enterovirus A71 (EV-A71) is an important emerging virus posing a threat to children under five years old. EV-A71 infection in infants or young children can cause hand-foot-and-mouth disease, herpangina, or severe neurological complications. However, there are still no effective antivirals for treatment of these infections. In this review, we summarize the antiviral compounds developed to date based on various targets of the EV-A71 life cycle. Moreover, development of a vaccine would be the most effective approach to prevent EV-A71 infection. Therefore, we also summarize the development and clinical progress of various candidate EV-A71 vaccines, including inactivated whole virus, recombinant VP1 protein, synthetic peptides, viral-like particles, and live attenuated vaccines.

Abstract
Objective: To describe the clinicopathological features of conjunctival actinic keratosis (AK) and relation to the infection of human papillomavirus (HPV). Method: Retrospective case series study. Eighteen cases (18 eyes) of conjunctival AK were obtained in Tianjin Eye Hospital and Institute (2005-2018). The clinical and histopathological features were studied. HPV was detected by a modified general primer HPV polymerase chain reaction (PCR) system in all formalin-fixed, paraffin-embedded specimens. Results: The male to female ratio was 5∶1. The mean age at diagnosis was 60 years (range: 43-79 years). Sixteen cases were located in the nasal interpalpebral region, and two cases were located in the temporal interpalpebral region. All cases were located in corneal limbus, and the mean distance of corneal invasion was 2 mm (range, 1-4 mm). The mean diameter was 4.6 mm (range, 2.0-8.0 mm). Clinically, most lesions (16 cases) appeared as a white or milky, flat plaque with clear borderline and conjunctival hyperemia; a few lesions (2 cases) showed a brown-black mass, partially white. Pathologically, conjunctival AK was a proliferation of epithelium with prominent parakeratosis or hyperkeratosis, stratum spinosm thickening and basal cell proliferation. Many AKs show solar elastosis and a mild inflammatory infiltrate of lymphocytes and plasma cells in the stroma. Most lesions (15 cases) were hypertrophic type, two cases were pigmented type, and one case was acantholytic type. HPV was negative in 18 cases. All case were removed by complete surgical excision. The rage of follow-up period was 1.0-10.4 years, ten cases were recorded, and no case recurred after surgical excision. Conclusions: Conjunctival AK is epithelial precancerous lesion that occurs in the keratoconjunctival margin. HPV infection might not be a causative factor in conjunctival AK.

Abstract
Hepatic fibrosis is a wound healing and scar repair reaction after liver injury, and is a common pathway for various chronic liver diseases. Activation and proliferation of hepatic stellate cells are the key links in the occurrence and development of hepatic fibrosis. Recent studies have shown that long non-coding RNAs are involved in regulating the activation, proliferation and apoptosis of hepatic stellate cells. Thus, probing its mechanism of action will provide a new strategy for the diagnosis, treatment and prognosis in liver fibrosis.

Abstract
Vasculogenic mimicry (VM) refers to the fluid-conducting channels formed by aggressive tumor cells rather than endothelial cells (EC) with elevated expression of genes associated with vascularization. VM has been considered as one of the reasons that glioblastoma becomes resistant to anti-VEGF therapy. However, the molecular basis underlying VM formation remains unclear. Here we report that the insulin-like growth factor-binding protein 2 (IGFBP2) acts as a potent factor to enhance VM formation in glioma. Evidence showed that elevated IGFBP2 expression was positively related with VM formation in patients with glioma. Enforced expression of IGFBP2 increased network formation of glioma cells in vitro by activating CD144 and MMP2 (Matrix Metalloproteinase 2). U251 cells with stable knockdown of IGFBP2 led to decreased VM formation and tumor progression in orthotopic mouse model. Mechanistically, IGFBP2 interacts with integrin α5 and β1 subunits and augments CD144 expression in a FAK/ERK pathway-dependent manner. Luciferase reporter and ChIP assay suggested that IGFBP2 activated the transcription factor SP1, which could bind to CD144 promoter. Thus, IGFBP2 acts as a stimulator of VM formation in glioma cells via enhancing CD144 and MMP2 expression.

Abstract
Inherited retinal disease (IRD) affects about 1 in 3000 to 1 in 5000 individuals and is now believed to be the most common cause of blindness registration in developed countries. Until recently, the management of such conditions had been exclusively supportive. However, advances in molecular biology and medical engineering have now seen the rise of a variety of approaches to restore vision in patients with IRDs. Optogenetic approaches are primarily aimed at rendering secondary and tertiary neurons of the retina light-sensitive in order to replace degenerate or dysfunctional photoreceptors. Such approaches are attractive because they provide a "causative gene-independent" strategy, which may prove suitable for a variety of patients with IRD. We discuss theoretical and practical considerations in the selection of optogenetic molecules, vectors, surgical approaches and review previous trials of optogenetics for vision restoration. Optogenetic approaches to vision restoration have yielded promising results in pre-clinical trials and a phase I/II clinical trial is currently underway (ClinicalTrials.gov NCT02556736). Despite the significant inroads made in recent years, the ideal optogenetic molecule, vector and surgical approach have yet to be established.

Abstract
Objective: To summarize the clinical pathologic characteristics of conjunctival osseous choristoma. Methods: Retrospective case series study. Six cases of conjunctival osseous choristoma between January 2009 and June 2016 from Tianjin Eye Hosptial were reviewed retrospectively. The clinical features, CT characteristics and histological characteristics were analyzed. Results: The 6 cases includes 3 male patients and 3 females. The age of the patients ranged from 4 to 20 years. Three cases involved with the right eye and the other 3 involved with the left eye. Major clinical feature of the patient is the flat uplift tumor in the superior temporal quadrant of the conjunctiva. CT features of conjunctival osseous choristoma revealed a oval calcium spot of eyeball surface. All the patients received surgery. Pathological examination showed that the tumor is composed of bone tissue which was surrounded by fibrous tissue, and Haversian canals are present in compact bone tissue. Five patients were followed for 23 months to 8 years. None of the patients relapsed after operation. Conclusions: The major feature of conjuncital osseous choristoma is a tumor in the superior temporal quadrant of conjunctiva. Imaging examination reveals a oval calcium spot of eyeball surface. Pathological examination reveals that the osseous tumor is composed of compact bone tissue which was surrounded by fibrous tissue.Haversian canals are present in compact bone tissue.Diagnosis is dependent on histopathological examination. It is not prone to relapse after complete resection surgery. (Chin J Ophthalmol, 2018, 54: 661-664).

Abstract
Background Cutaneous lupus erythematosus (CLE) includes a broad range of dermatologic manifestations. Periorbital involvement, however, is a relatively rare clinical presentation of CLE. Objectives This clinical study aimed to investigate the characteristics of this unique presentation of CLE in tertiary medical centers. Methods We enrolled patients with periorbital erythema and swelling as the presenting sign of lupus erythematosus, from January 2003 to November 2017, using the data of 553 pathologically proven CLE cases from the registration database of the Chang Gung Memorial Hospitals in Taiwan. Results We enrolled a total of 25 patients. The mean age was 46.7 years and 68% of the patients were female. Most of the patients (84.0%) presented with unilateral involvement, with the left orbit involved in 15 patients (60%); the upper eyelid was the most frequently involved (72%). Mean duration between the onset of clinical manifestations and the diagnosis of CLE was approximately 59 weeks. Nineteen patients had been previously misdiagnosed. All patients had features compatible with CLE on histopathological examination. In contrast, laboratory analysis of the autoimmune profile often revealed negative results, including those for antinuclear antibodies (25%). Notably, anti-SSA/SSB (45.5%) showed the highest positive rate. During follow-up, six patients developed systemic lupus erythematosus (SLE) and two patients developed Sjögren syndrome. Conclusions The diagnosis of CLE presenting as periorbital erythema and swelling is often delayed because of clinical mimicry and the high proportion of negative results on autoantibody tests. Increased clinical suspicion and prompt histopathological examination are crucial for early diagnosis. Moreover, one-fourth of the patients ultimately developed SLE, which highlights the importance of clinical awareness.

Abstract
Specific ethnic genetic backgrounds are associated with the risk of Stevens-Johnson syndrome / toxic epidermal necrolysis (SJS/TEN) especially in Asians. However, there have been no large cohort, multiple-country epidemiological studies of medication risk related to SJS/TEN in Asian populations. Thus, we analyzed the registration databases from multiple Asian countries who were treated during 1998-2017. A total 1,028 SJS/TEN cases were identified with the algorithm of drug causality for epidermal necrolysis. Furthermore, those medications labeled by the US Food and Drug Administration (FDA) as carrying a risk of SJS/TEN were also compared with the common causes of SJS/TEN in Asian countries. Oxcarbazepine, sulfasalazine, COX-II inhibitors, and strontium ranelate were identified as new potential causes. In addition to sulfa drugs and beta-lactam antibiotics, quinolones were also a common cause. Only one acetaminophen-induced SJS was identified, while several medications (e.g., oseltamivir, terbinafine, isotretinoin, and sorafenib) labeled as carrying a risk of SJS/TEN by the FDA were not found to have caused any of the cases in the Asian countries investigated in this study.

Abstract
OBJECTIVES To study the differential genes expression in the early stage of acute renal ischemia-reperfusion injury and explore potential molecular mechanisms. METHODS The ischemia-reperfusion model was made via clamping renal artery of rat. The microarray detection and bioinformatics analyzing of the genes expression were performed. Differentially expressed genes were screened and related cellular activities and signaling pathways were analyzed in early stage of acute kidney injury. Meanwhile, molecules closely relative to acute kidney injury were explored by establishing a biological network of the differentially expressed genes, and the results were verified by real-time PCR. RESULTS A total of 151 genes showed differential expression in this study, including 132 up-regulated and 19 down-regulated genes. Cell proliferation, cytokines mediated signaling transduction and immune responses were greatly enriched by GO and KEGG analysis. The results of real-time PCR showed that compared with control groups, three selected genes (ANXA1, PHLDA1 and KLF6) which related to the acute kidney injury had an obvious differential expression in the early stage of disease. The multiple of increase was essentially the same as the multiple detected by microarray. CONCLUSIONS This study shows differential gene expression profile, related biological processes and signaling pathways involved in the early stage of acute kidney injury. ANXA1, PHLDA1 and KLF6 may play a role in the pathogenesis of acute kidney injury.

Abstract
Objective: To investigate the relationship between expression of PDGFRA/CMYC and clinicopathologic features of extranodal NK/T-cell lymphoma. Methods: Fifty-four cases of extranodal NK/T-cell lymphoma were included in the study.Immunohistochemistry was used to detect the expression of CD20, CD2, CD3, CD56, TIA1, GrB, Ki-67, PDGFRA and CMYC.In situ hybridization was performed to detect the presence of EBV encoded small RNA (EBER). Fifty cases of nasopharyngeal mucosal lymphoid tissue hyperplasia were used as normal control. Results: Among 54 cases of ENKTL, CD2, CD3, GrB, and TIA1 were expressed in all the tumors. CD56 was expressed in 47 cases (81.0%) and CD20 was not detectable in any cases. Ki-67 proliferative index expression of > 60% was found in 45 cases (83.3%). In situ hybridization for EBER was positive in all cases (100%). The positive expression rates of PDGFRA and CMYC in extranodal NK/T-cell lymphomas were 51.9%(28/54) and 53.7%(29/54), respectively, much higher than those in nasopharyngeal mucosal lymphoid tissue hyperplasia (0, P<0.05). There was a positive correlation between PDGFRA and CMYC (r=0.295, P<0.05). The expression of CMYC was correlated with clinical efficacy (P<0.05), but not with gender, age, Ann Arbor stage, B symptoms and therapeutic regimen (all P>0.05). The expression of PDGFRA was correlated with B symptoms (P<0.05), while not with gender, age, Ann Arbor stage, therapeutic regimen and clinical efficacy (all P>0.05). The co-expression of PDGFRA and CMYC was not correlated with gender, age, Ann Arbor stage, B symptoms, therapeutic regimen and clinical efficacy (P>0.05). Univariate analysis showed that the stage, clinical efficacy, CMYC protein and the co-expression of PDGFRA and CMYC were significantly correlated with the prognosis. The overall survival of the patients with CMYC positive expression was shorter than of that of the patients with negative expression (P<0.05). Multivariable Cox regression analysis further confirmed that clinical stage, CMYC protein expression, and the co-expression of PDGFRA and CMYC were independent prognostic factors in patients with extranodal NK/T-cell lymphoma. Conclusion: CMYC protein, and the co-expression of PDGFRA and CMYC can be as an independent prognostic factor in patients with extranodal NK/T-cell lymphoma and influence the prognosis of patients.

Abstract
OBJECTIVE To investigate the risk and genetic association of oxcarbazepine-induced cutaneous adverse reactions (OXC-cADRs), including Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), in Asian populations (Chinese and Thai). METHODS We prospectively enrolled patients with OXC-cADRs in Taiwan and Thailand from 2006 to 2014, and analyzed the clinical course, latent period, drug dosage, organ involvement, complications, and mortality. We also investigated the carrier rate of HLA-B*15:02 and HLA-A*31:01 of patients with OXC-cADRs and compared to OXC-tolerant controls. The incidence of OXC-SJS/TEN was compared with carbamazepine (CBZ)-induced SJS/TEN according to the nationwide population dataset from the Taiwan National Health Insurance Research Database. RESULTS We enrolled 50 patients with OXC-cADRs, including 20 OXC-SJS/TEN and 6 drug reaction with eosinophilia and systemic symptoms, of Chinese patients from Taiwan and Thai patients from Thailand. OXC-cADRs presented with less clinical severity including limited skin detachment (all ≦5%) and no mortality. There was a significant association between HLA-B*15:02 and OXC-SJS (p = 1.87 × 10-10; odds ratio 27.90; 95% confidence interval [CI] 7.84-99.23) in Chinese and this significant association was also observed in Thai patients. The positive and negative predictive values of HLA-B*15:02 for OXC-SJS/TEN were 0.73% and 99.97%, respectively. HLA-A*31:01 was not associated with OXC-cADRs. The incidence and mortality of OXC-SJS/TEN was lower than CBZ-STS/TEN in new users (p = 0.003; relative risk 0.212; 95% CI 0.077-0.584). CONCLUSIONS Our findings suggest that HLA-B*15:02 is significantly associated with OXC-SJS in Asian populations (Chinese and Thai). However, the severity and incidence of OXC-SJS/TEN are less than that of CBZ-SJS/TEN. The need for preemptive HLA-B*15:02 screening should be evaluated further.

Abstract
Objective: To observe the clinical and pathological features of uveal metastatic carcinoma. Methods: It was a retrospective case series study. The clinical manifestation, growth pattern, tumor types and relative pathological features of 13 patients visiting from January 1980 to December 2014 with uveal metastatic carcinoma in Tianjin Eye Hospital were analyzed retrospectively. Results: There were 13 cases, 6 cases of male and 7 of female. Age was from 37.0 to 66.0 years old. The mean age was 52.1 years old. all cases were monocular. There were 5 cases with right eye and 8 cases with left eye. Among 13 cases, 10 tumors were in posterior choroid, one tumor was in anterior choroid and ciliary body, 2 tumors were in the iris. There were 5 patients with lung cancer, 4 patients with breast cancer, 1 patient with prostate cancer, 1 patient with thyroid cancer and 1 patient with esophageal cancer. The primary tumor wasn't found in 1 patient. The rapid decrease of visual acuity showed in 10 patients with posterior choroidal metastatic carcinoma, 8 of them accompanied with extensive retinal detachment and 6 of them had secondary glaucoma. The multiple gray-white nodule or pink cauliflower mass on the papillary margin of iris were showed respectively in 2 patients with iris metastatic carcinoma. The pathological examination found that posterior choroidal metastatic carcinoma mainly located in temporal or nasal side choroids in 10 cases, among them, local or diffuse flat choroidal masses showed in 6cases, extensive mass involving choroid and ciliary body showed in 1 case, large nodular or globular choroidal mass showed in 2 cases, choroidal mass surrounded the optic disc in 1 case, optic nerve invasion showed in 3 cases and extraocular or orbital invasion showed in 3 cases. The scleral and subconjunctival invasion showed in 1 case of anterior choroid and ciliary body metastatic carcinoma. Conclusions: Uveal metastatic carcinoma manifested various growth pattern, the rapid decrease of visual acuity, flat or nodular choroidal solid mass, secondary retinal detachment and glaucoma were common clinical features. Some cases might invade extraocular or orbital tissue. (Chin J Ophthalmol, 2016, 52: 769-774).

Abstract
The goal of the current study was to investigate the effects of pollution on aquatic organisms in the Yongcheng coal mine subsidence area. Crucian carp (Carassius auratus) were collected from Yongcheng natural fishpond (experimental group) and Tianmu Lake (control group), and the spleens were isolated for analysis. Subsequently, histological changes, DNA damage, and antioxidant enzyme activity were assessed. The result showed that there were more vacuoles, widened blood sinus cavities, increased partial dot necrosis, and a larger number of brown-yellow nodules in splenic sections stained with hematoxylin and eosin in the experimental group than in the control group. Additionally, it was not easy to distinguish red pulp from white pulp in the experimental group. The antioxidant enzyme activity in the experimental group was significantly lower than that in the control group (P < 0.01). Comet assay results showed varying degrees of tailing and DNA chain breaks in the experimental group, and further analysis demonstrated that the tail length and tail moment were significantly increased compared to those in the control group (P < 0.01). These results suggest that the spleen antioxidant defense system was severely damaged in crucian carp from the Yongcheng coal mine subsidence area.

Abstract
Doping at the rare-earth site by divalent alkaline-earth ions in perovskite lattice has witnessed a variety of magnetic and electronic orders with spatially correlated charge, spin and orbital degrees of freedom. Here, we report an antisite disorder driven spontaneous exchange bias effect as a result of hole carrier (Sr(2+)) doping in La(2-x)Sr(x)CoMnO6 (0 < x < 1) double perovskites. X-ray diffraction and Raman spectroscopy have evidenced an increase in disorder with the increase of Sr content up to x = 0.5 and thereby a decrease from x = 0.5 to 1. X-ray absorption spectroscopy has revealed that only Co is present in the mixed valence of Co(2+) and Co(3+) states with Sr doping to compensate the charge neutrality. Magnetotransport is strongly correlated with the increase of antisite disorder. The antisite disorder at the B-site interrupts the long-range ferromagnetic order by introducing various magnetic interactions and instigates reentrant glassy dynamics, phase separation and canted type antiferromagnetic behavior with the decrease of temperature. This leads to a novel magnetic microstructure with unidirectional anisotropy that causes a spontaneous exchange bias effect that can be tuned with the amount of antisite disorder.

Abstract
The triangle sail mussel, Hyriopsis cumingii, is the most important freshwater pearl mussel in China. However, the mechanisms underlying its chitin-mediated shell and nacre formation remain largely unknown. Here, we characterized a chitin synthase (CS) gene (HcCS1) in H. cumingii, and analyzed its possible physiological function. The complete ORF sequence of HcCS1 contained 6903 bp, encoding a 2300-amino acid protein (theoretical molecular mass = 264 kDa; isoelectric point = 6.22), and no putative signal peptide was predicted. A myosin motor head domain, a CS domain, and 12 transmembrane domains were found. The predicted spatial structures of the myosin head and CS domains were similar to the electron microscopic structure of the heavy meromyosin subfragment of chicken smooth muscle myosin and the crystal structure of bacterial cellulose synthase, respectively. This structural similarity indicates that the functions of these two domains might be conserved. Quantitative reverse transcription PCR results showed that HcCS1 was present in all detected tissues, with the highest expression levels detected in the mantle. The HcCS1 transcripts in the mantle were upregulated following shell damage from 12 to 24 h post-damage, and they peaked (approximately 1.5-fold increase) at 12 h after shell damage. These findings suggest that HcCS1 was involved in shell regeneration, and that it might participate in shell and nacre formation in this species via chitin synthesis. HcCS1 might also dynamically regulate chitin deposition during the process of shell and nacre formation with the help of its conserved myosin head domain.

Abstract
EV71 (enterovirus 71) RNA contains an internal ribosomal entry site (IRES) that directs cap-independent initiation of translation. IRES-dependent translation requires the host’s translation initiation factors and IRES-associated trans-acting factors (ITAFs). We reported recently that mRNA decay factor AUF1 is a negative-acting ITAF that binds IRES stem-loop II. We also reported that the small RNA-processing enzyme Dicer produces at least four small RNAs (vsRNAs) from the EV71 IRES. One of these, vsRNA1, derived from IRES stem-loop II, reduces IRES activity and virus replication. Since its mechanism of action is unknown, we hypothesized that it might control association of ITAFs with the IRES. Here, we identified the mRNA stability factor HuR and the RISC subunit Argonaute 2 (Ago2) as two ITAFs that bind stem-loop II. In contrast to AUF1, HuR and Ago2 promote EV71 IRES activity and virus replication. In vitro RNA-binding assays revealed that vsRNA1 can alter association of Ago2, HuR, and AUF1 with stem-loop II. This presents a possible mechanism by which vsRNA1 could control viral translation and replication.
