Abstract
BACKGROUND Depression and insomnia are common co-occurring psychiatric problems among older adults who have had strokes. Nevertheless, symptom-level relationships between these disorders remain unclear. OBJECTIVES In this study, we compared inter-relationships of depression and insomnia symptoms with life satisfaction among older stroke patients and stroke-free peers in the United States. METHODS The study included 1026 older adults with a history of stroke and 3074 matched controls. Data were derived from the US Health and Retirement Study. Depression, insomnia and life satisfaction were assessed. Propensity score matching was employed to identify demographically-similar groups of stroke patients and controls. Central and bridge symptoms were assessed using Expected influence (EI) and bridge EI, respectively. RESULTS The prevalence of depression in the stroke group (25.0 %) was higher than that of controls (14.3 %, P < 0.001). In stroke group, "Feeling depressed" (CESD1; EI: 5.80), "Feeling sad" (CESD7; EI: 4.67) and "Not enjoying life" (CESD6; EI: 4.51) were the most central symptoms, while "Not feel rested in the morning" (JSS4; BEI: 1.60), "Everything was an effort" (CESD2; BEI: 1.21) and "Waking up during the night" (JSS2; BEI: 0.98) were key bridge symptoms. In controls, the most central symptoms were "Lack of happiness" (CESD4; EI: 6.45), "Feeling depressed" (CESD1; EI: 6.17), and "Feeling sad" (CESD7; EI: 6.12). Furthermore, "Feeling tired in the morning" (JSS4; BEI: 1.93), "Everything was an effort" (CESD2; BEI: 1.30), and "Waking up too early" (JSS3; BEI: 1.12) were key bridge symptoms. Life satisfaction had the most direct associations with "Not enjoying life" (CESD6) and "Feeling lonely" (CESD5) in the two groups, respectively. CONCLUSION Older adults with stroke exhibited more severe depression and insomnia symptoms. Interventions targeting central and bridge symptoms may help to mitigate the co-occurrence of these symptoms.

Abstract
BACKGROUND Few studies have examined the associations between pain trajectories and cognitive function in older adults. This study explored the associations between pain trajectories and different cognitive domains in older adults from a network perspective. METHODS Data on pain trajectories were derived from the Health and Retirement Study between 2010 and 2020 using latent class growth analyses. Measurements of key cognition domains, including memory, attention, calculation, orientation and language, were included. Linear regression and network analysis were performed to evaluate the associations between different pain trajectories and cognition. RESULTS A total of 9,551 older adults were included in this study and three trajectories of pain were identified. After controlling for the covariates, persistent severe pain trajectory was associated with poorer overall cognition, memory and calculation ability when compared to mild or non-persistent pain trajectory. In the pain and cognition network model, memory (expected influence (EI) = 0.62), language (EI = 0.58) and calculation (EI = 0.41) were the most central domains. CONCLUSIONS Pain trajectories appeared stable over time among older adults in this study. Severity of persistent pain was an important risk factor for poor cognition, especially in relation to memory and calculation domains. Interventions targeting memory, language and calculation domains might be useful in addressing cognitive decline in older adults with persistent pain.

Abstract
OBJECTIVES Depression and loneliness co-occur frequently. This study examined interactive changes between depression and loneliness among older adults prior to and during the COVID-19 pandemic from a longitudinal network perspective. METHODS This network study was based on data from three waves (2016-2017, 2018-2019, and 2020) of the English Longitudinal Study of Ageing (ELSA). Depression and loneliness were measured with the eight-item version of the Center for Epidemiologic Studies Depression Scale (CESD-8) and three item version of the University of California Los Angeles (UCLA) Loneliness Scale, respectively. A network model was constructed using an Ising Model while network differences were assessed using a Network Comparison Test. Central symptoms were identified via Expected Influence (EI). RESULTS A total of 4,293 older adults were included in this study. The prevalence and network of depression and loneliness did not change significantly between the baseline and pre-pandemic assessments but increased significantly from the pre-pandemic assessment to during COVID-19 assessment. The central symptom with the strongest increase from pre-pandemic to pandemic assessments was "Inability to get going" (CESD8) and the edge with the highest increase across depression-loneliness symptom communities was "Lack companionship" (UCLA1) - "Inability to get going" (CESD8). Finally, "Feeling depressed" (CESD1) and "Everything was an effort" (CESD2) were the most central symptoms over the three assessment periods. CONCLUSIONS The COVID-19 pandemic was associated with significant changes in the depression-loneliness network model. The most changed symptoms and edges could be treatment targets for reducing the risk of depression and loneliness in older adults.

Abstract
Objective: To analyze the clinical efficacy of intrathyroid thymic carcinoma (ITTC). Methods: This study retrospectively analyzed the clinical data of 21 patients with ITTC diagnosed and treated at the First Affiliated Hospital of Zhengzhou University from January 2018 to July 2023, including 9 males and 12 females, with a median age of 52 years (40-60 years old). Results: There is a correlation between the maximum diameter of the tumor (≥40 mm) and lymph node metastasis (P=0.044). Seventeen patients received surgical treatment, and 4 patients only received chemotherapy. During the follow-up period, a total of 4 patients experienced death or progression, with a 2-year mortality or progression free survival rate of 74.8%. Conclusions: The prognosis of ITTC is good, and surgical treatment is the preferred treatment option, lymph node metastasis is significantly correlated with prognosis. The radiotherapy and chemotherapy of ITTC need to be determined based on the patient's condition.

Abstract
BACKGROUND Depressive and anxiety symptoms (depression and anxiety hereafter) are common among psychiatric patients and their caregivers during the COVID-19 pandemic. Network analysis is a novel method to assess the associations between psychiatric syndromes/disorders at the symptom level. This study examined depression and anxiety among caregivers of psychiatric inpatients during the late stage of the COVID-19 pandemic from the perspective of network analysis. METHODS A total of 1101 caregivers of psychiatric inpatients were included in this study. The severity of depression was assessed using the nine-item Patient Health Questionnaire (PHQ-9), while anxiety was assessed with the seven-item Generalized Anxiety Disorder Scale (GAD-7). The expected index (EI) and bridge EI index were used to identify the central and bridge symptoms, respectively. The stability of the network was evaluated via a case-dropping bootstrap procedure. RESULTS The prevalence of depression and anxiety were 32.4 % (95%CI: 29.7 %-35.3 %) and 28.0 % (95%CI: 25.4 %-30.7 %), respectively while the prevalence of comorbid depression and anxiety was 24.9 % (95%CI: 22.4 %-27.6 %). The most central symptom was "Fatigue", followed by "Trouble Relaxing" and "Restlessness". The highest bridge symptom was "Restlessness", followed by "Uncontrollable worry" and "Suicide ideation". The bootstrap test indicated that the whole network model was stable, and no network difference was detected between genders and between different education levels. CONCLUSIONS Depression, anxiety, and comorbid depression and anxiety were common among caregivers of psychiatric inpatients during the late stage of the COVID-19 pandemic. Central and bridge symptoms identified in this network analysis should be considered key target symptoms to address in caregivers of patients.

Abstract
Post-infection sequelae of COVID-19 (PISC) have raised public health concerns. However, it is not clear whether infected mental health professionals (MHPs) with PISC have experienced more psychiatric symptoms than MHPs without PISC do. This study examined differences in the prevalence of self-reported depression, anxiety, insomnia and suicidality as well as the network structures of these symptoms between these two groups. Participants completed questionnaire measures of psychiatric symptoms and demographics. Expected influence was used to measure centrality of symptoms and network comparison tests were adopted to compare differences in the two network models. The sample comprised 2,596 participants without PISC and 2,573 matched participants with PISC. MHPs with PISC had comparatively higher symptom levels related to depression (55.2% vs. 23.5 %), anxiety (32.0% vs. 14.9 %), insomnia (43.3% vs. 17.3 %), and suicidality (9.6% vs. 5.3 %). PHQ4 ("Fatigue"), PHQ6 ("Guilt"), and GAD2 ("Uncontrollable Worrying") were the most central symptoms in the "without PISC" network model. Conversely, GAD3 ("Worry too much"), GAD5 ("Restlessness"), and GAD4 ("Trouble relaxing") were more central in the "with PISC" network model. In sum, MHPs with PISC experienced comparatively more psychiatric symptoms and related disturbances. Network results provide foundations for the expectation that MHPs with PISC may benefit from interventions that address anxiety-related symptoms, while those without PISC may benefit from interventions targeting depression-related symptoms.

Abstract
Background The 2019 novel coronavirus disease (COVID-19) outbreak affected people's lifestyles and increased their risk for depressive and anxiety symptoms (depression and anxiety, respectively hereafter). We assessed depression and anxiety in residents of Macau during "the 6.18 COVID-19 outbreak" period and explored inter-connections of different symptoms from the perspective of network analysis. Methods In this cross-sectional study, 1,008 Macau residents completed an online survey comprising the nine-item Patient Health Questionnaire (PHQ-9) and seven-item Generalized Anxiety Disorder Scale (GAD-7) to measure depression and anxiety, respectively. Central and bridge symptoms of the depression-anxiety network model were evaluated based on Expected Influence (EI) statistics, while a bootstrap procedure was used to test the stability and accuracy of the network model. Results Descriptive analyses indicated the prevalence of depression was 62.5% [95% confidence interval (CI) = 59.47-65.44%], the prevalence of anxiety was 50.2% [95%CI = 47.12-53.28%], and 45.1% [95%CI = 42.09-48.22%] of participants experienced comorbid depression and anxiety. "Nervousness-Uncontrollable worry" (GADC) (EI = 1.15), "Irritability" (GAD6) (EI = 1.03), and "Excessive worry" (GAD3) (EI = 1.02) were the most central symptoms, while "Irritability" (GAD6) (bridge EI = 0.43), "restlessness" (GAD5) (bridge EI = 0.35), and "Sad Mood" (PHQ2) (bridge EI = 0.30) were key bridge symptoms that emerged in the network model. Conclusion Nearly half of residents in Macau experienced comorbid depression and anxiety during the 6.18 COVID-19 outbreak. Central and bridge symptoms identified in this network analysis are plausible, specific targets for treatment and prevention of comorbid depression and anxiety related to this outbreak.

Abstract
BACKGROUND Associations between the microbiome-gut-brain axis and dementia have attracted considerable attention in research literature. This study examined the microbiome-gut-brain axis and dementia-related research from a bibliometric perspective. METHODS A search for original research and review articles on the microbiome-gut-brain axis and dementia was conducted in the Web of Science Core Collection (WOSCC) database. The R package "bibliometrix" was used to collect information on countries, institutions, authors, journals, and keywords. VOSviewer software was used to visualize the co-occurrence network of keywords. RESULTS Overall, 494 articles met the study inclusion criteria, with an average of 29.64 citations per article. Corresponding authors of published articles were mainly from China, the United States and Italy. Zhejiang University in China and Kyung Hee University in Korea were the most active institutions, while the Journal of Alzheimer's Disease and Nutrients published the most articles in this field. Expected main search terms, "Parkinson disease" and "chain fatty-acids" were high-frequency keywords that indicate current and future research directions in this field. CONCLUSIONS This bibliometric study helped researchers to identify the key topics and trends in the microbiome-gut-brain axis and dementia-related research. High-frequency keywords identified in this study reflect current trends and possible future directions in this field related to methodologies, mechanisms and populations of interest.

Abstract
BACKGROUND Nickel, the fifth most common element on Earth, is the leading inducer of contact allergies in humans, with potent immunological effects. Nickel-induced contact allergies predominantly affect females. Maternal exposure to nickel has been associated with several developmental abnormalities. However, how a maternal nickel exposure affects the development of atopic diathesis and immune abnormalities in children has never been addressed. OBJECTIVES We aimed to determine whether maternal Ni exposure affects the development of atopic dermatitis and immune abnormalities in their children. METHODS Using a birth cohort study, we analysed 140 mother-child pairs recruited in 2012-2015 from central Taiwan. Maternal exposure to nickel was estimated using urinary nickel levels measured by inductively coupled plasma mass spectrometry (ICP-MS). The serum levels of 65 analytes and IgE in 3-year-old children were profiled with a multiplex ELISA. The correlation between the maternal urinary nickel concentration and serum analyte levels was assessed using Spearmen's correlation. Multivariant regression analysis was performed to evaluate the association between maternal urinary nickel levels and serum analyte concentrations in their children. RESULTS The geometric means of the maternal urinary nickel and the children's serum IgE levels were 2.27 μg/L and 69.71 IU/ml, respectively. The maternal nickel exposure was associated with increased serum levels of IL-1β, IL-2, TNF-α, and leukaemia inhibitory factor (LIF) but with decreased serum levels of matrix metalloproteinase-1 (MMP-1), IL-2R, and eotaxin-1 in the children. In addition, the development of childhood atopic dermatitis at 3 years old was significantly associated with the child's serum levels of IgE and IL-2R, but it was negatively associated with the maternal nickel exposure. CONCLUSIONS This is the first study showing the potential immunological effects of maternal nickel exposure in their children at an early developmental stage.

Abstract
Background Schizophrenia (SCZ) is a severe psychiatric disorder that involves inflammatory processes. The aim of this study was to explore the field of inflammation-related research in SCZ from a bibliometric perspective. Methods Regular and review articles on SCZ- and inflammation-related research were obtained from the Web of Science Core Collection (WOSCC) database from its inception to February 19, 2022. R package "bibliometrix" was used to summarize the main findings, count the occurrences of the top keywords, visualize the collaboration network between countries, and generate a three-field plot. VOSviewer software was applied to conduct both co-authorship and co-occurrence analyses. CiteSpace was used to identify the top references and keywords with the strongest citation burst. Results A total of 3,596 publications on SCZ and inflammation were included. Publications were mainly from the USA, China, and Germany. The highest number of publications was found in a list of relevant journals. Apart from "schizophrenia" and "inflammatory", the terms "bipolar disorder," "brain," and "meta-analysis" were also the most frequently used keywords. Conclusions This bibliometric study mapped out a fundamental knowledge structure consisting of countries, institutions, authors, journals, and articles in the research field of SCZ and inflammation over the past 30 years. The results provide a comprehensive perspective about the wider landscape of this research area.

Abstract
OBJECTIVE To systematically examine the efficacy and safety of antidepressants for the treatment of coronavirus disease 2019 (COVID-19). METHODS A systematic search was performed independently by two researchers based on Chinese Journal Net, WanFang, PsycINFO, Cochrane Library, PubMed, and EMBASE. RESULTS Seven studies (n = 92,947) including three retrospective studies (n = 91,083), two randomized clinical trials (RCTs, n = 1649), two prospective cohort study (n = 215) involving (n = 92,947) patients with COVID-19 were examined. For RCTs, fluvoxamine outperformed placebo in reducing clinical deterioration and hospitalisation for COVID-19 patients. For retrospective studies, antidepressants (2 studies) and fluoxetine (1 study) possibly reduced the risk of mortality in patients with COVID-19. Results from two remaining studies supported the superiority of fluvoxamine in reducing risk of mortality in COVID-19 patients. The two RCTs that examined the safety of fluvoxamine for COVID-19 patients found inconsistent results but no significant group differences in the dropout rate. CONCLUSION This systematic review found emerging evidence for fluvoxamine in reducing the risk of mortality and hospitalisation in COVID-19 patients, but inconsistent evidence for the safety of fluvoxamine in COVID-19 patients. More studies are needed to determine the efficacy and safety of antidepressants for the treatment of COVID-19.

Abstract
Objective: To explore the relationship between pathogens in the olfactory cleft area and olfactory disorders in patients with upper respiratory inflammation (URI) during the prevention and control of 2019 novel coronavirus disease (COVID-19). Methods: A total of 234 URI patients including acute upper respiratory infection, chronic rhinosinusitis (CRS), allergic rhinitis (AR) were continuously selected from September 2020 to March 2021 in Beijing Anzhen Hospital and 98 healthy adults were enrolled as controls. The secretions from the olfactory cleft of all subjects were collected with nasal swabs under nasal endoscopy. Multiple real-time fluorescent quantitative polymerase chain reaction detection method was used to detect nucleic acids of 33 types of respiratory pathogenic microorganism. Sniffin' Sticks olfactory test was performed on all patients with URI. URI patients with olfactory dysfunction were followed up for 9 (8, 10) months (M (Q1, Q3)). SPSS 20.0 software was used for statistical analysis. Results: Among the 98 controls, 9 (9.18%) were positive for pathogenic microorganisms, including 1 (1.02%) rhinovirus, 1 (1.02%) parainfluenza virus type 3, 3 (3.06%) enterovirus, 1 (1.02%) staphylococcus aureus and 3 (3.06%) Moraxella catarrhalis. Among the 234 URI patients, 111 (47.44%) had olfactory disorders and 123 (52.56%) had normal sense of smell. In the olfactory disorder group (111 cases), 38 cases (34.23%) were positive for pathogenic microorganisms, and 4 cases (3.60%) were mixed infection, including 11 cases of rhinovirus (9.91%), 5 cases of coronavirus 229E (4.50%), 2 cases of coronavirus OC43/NL63 (1.80%), 3 cases of parainfluenza virus type 1 (2.70%), 2 cases of enterovirus (1.80%), 1 case of influenza B virus type BV (0.90%), 11 cases of Staphylococcus aureus (9.91%), 7 cases of Moraxella catarrhalis (6.31%), and 1 case of Klebsiella pneumoniae (0.90%). In the normal smell group (123 cases), 18 cases (14.63%) were positive for pathogenic microorganisms, and 1 case (0.81%) was mixed infection, including 3 cases of rhinovirus (2.44%), 4 cases of coronavirus 229E (3.25%), 1 case of Influenza virus type 3 (0.81%), 3 cases of enterovirus (2.44%), 3 cases of Staphylococcus aureus (2.44%), 4 cases of Moraxella catarrhalis (3.25%), and 1 case of Klebsiella pneumoniae (0.81%). Univariate analysis between the two groups found that there were significant differences in the detection rate of pathogenic microorganisms, rhinovirus and Staphylococcus aureus between the groups (all P<0.05). The detection rate of parainfluenza virus type 1, Staphylococcus aureus, and rhinovirus were different between the patients with olfactory disorder and normal olfactory function in the three subgroups of acute upper respiratory tract infection, CRS and AR, respectively (χ2 value was 3.88, 4.53 and 4.73, respectively, all P<0.05). During the follow-up period, among the 111 patients with olfactory disorder, 71 (63.96%) patients' olfactory function returned to normal, 32 (28.83%) patients' olfactory function improved but not completely returned to normal, 8 (7.21%) patients' olfactory function did not improve. Conclusions: During the prevention and control of COVID-19, rhinovirus or Staphylococcus aureus infection or colonization of URI patients is closely related to olfactory disorders. Parainfluenza virus type 1 infection can cause relatively persistent olfactory disorders in patients with acute upper respiratory tract infection. Staphylococcus aureus and rhinovirus colonization are related to the occurrence of olfactory dysfunction in CRS and AR patients respectively.

Abstract
Background: Macau is a densely populated international tourist city. Compared to most tensely populated countries/territories, the prevalence and mortality of COVID-19 in Macau are lower. The experiences in Macau could be helpful for other areas to combat the COVID-19 pandemic. This article introduced the endeavours and achievements of Macau in combatting the COVID-19 pandemic. Method: Both qualitative and quantitative analysis methods were used to explore the work, measures, and achievements of Macau in dealing with the COVID-19 pandemic. Results: The results revealed that Macau has provided undifferentiated mask purchase reservation services, COVID-19 vaccination services to all residents and non-residents in Macau along with delivering multilingual services, in Chinese, English and Portuguese, to different groups of the population. To facilitate the travels of people, business and trades between Macau and mainland China, the Macau government launched the Macau Health Code System, which uses the health status declaration, residence history declaration, contact history declaration of the declarant to match various relevant backend databases within the health authority and provide a risk-related colour code operations. The Macau Health Code System connects to the Chinese mainland's own propriety health code system seamlessly, whilst effectively protecting the privacy of the residents. Macau has also developed the COVID-19 Vaccination Appointment system, the Nucleic Acid Test Appointment system, the Port and Entry/Exit Quarantine system, the medical and other supporting systems. Conclusion: The efforts in Macau have achieved remarkable results in COVID-19 prevention and control, effectively safeguarding the lives and health of the people and manifesting the core principle of “serving the public”. The measures used are sustainable and can serve as an important reference for other countries/regions.

Abstract
Background: The 2019 novel coronavirus disease (COVID-19) outbreak had a detrimental impact on the mental health of older adults. This study evaluated the central symptoms and their associations in the network of depressive symptoms and compared the network structure differences between male and female older adults in Hong Kong. Methods: Altogether, 3,946 older adults participated in this study. We evaluated the centrality indicators for network robustness using stability and accuracy tests, and examined the potential differences between the structure and connectivity of depression networks in male and female older adults. Results: The overall prevalence of depressive symptoms was 43.7% (95% CI=40.6-46.7%) in males, and 54.8% (95% CI=53.1-56.5%) in females (P<0.05). Sad Mood, Guilt, Motor problems and Lack of Energy were influential symptoms in the network model. Gender differences were found in the network global strength, especially in the following edges: Sad Mood--Guilt, Concentration--Guilt, Anhedonia--Motor, Lack of Energy--Suicide, Appetite--Suicide and Concentration--Suicide. Conclusions: Central symptoms in the depressive symptom network among male and female older adults may be prioritized in the treatment and prevention of depression during the pandemic.

Abstract
Objective: To summarize the clinical characteristics and species distribution of nontuberculous mycobacteria(NTM). Methods: We conducted a retrospectively chart review of 453 adult patients with 532 positive cultures with NTM diagnosed and treated in Peking Union Medical College Hospital from January 2014 to December 2018. The information including clinical findings, imaging and etiological data were obtained from clinical examination system. Among these 453 patients, 75 cases met the diagnostic criteria for NTM, with detailed clinical data, culture results and radiological images. Of these patients, 38 were males and 37 were females, with an average age of (50.8±16.2) years. Clinical manifestations, imaging features, NTM species and treatment were analyzed. Results: Among 75 NTM patients, 43 cases (57.3%, 43/75) were infected with Mycobacterium avium Complex (MAC)/intracellular, 18 cases (24.0%, 18/75) with Mycobacterium turtle/abscess, and 7 cases (9.3%, 7/75) with Mycobacterium kansasii. Comorbidities existed in 64.0% patients (48/75). The top two common comorbidities were previous tuberculosis (25.3%, 19/75) infection and clinical bronchiectasis (18.7%, 14/75). After the respiratory disease (82.7%, 62/75), we identified bloodstream as the most frequent manifestation of NTM infection (25.3%, 19/75). MAC was often associated with infection in respiratory system and bloodstream, while rapidly growing mycobacteria (RGM) was more commonly detected in lymph nodes and skin and soft tissues. Cough/expectoration (77.4%, 48/62) was the most common clinical symptom of NTM disease, followed by fever and dyspnea. The frequent imaging findings were nodules (41.9%, 26/62), bronchiectasis (37.1%, 23/62), and fibrous cavities (24.2%, 15/62). In disseminated NTM disease, 94.7% (18/19) patients had underlying diseases and 89.5% (17/19) patients had long-term immunosuppression. Conclusion: The most common NTM species was Mycobacterium avium/intracellular in our series. The predominant infected organ was the respiratory system. Previous tuberculosis history likely increased the risk of infection.

Abstract
Sclerotinia sclerotiorum is one of the most damaging and economically important necrotrophic plant pathogens, infecting more than 400 plant species globally. Although the phenylpyrrole fungicide fludioxonil has high activity against S. sclerotiorum, reports indicate that there is also substantial potential for the development of fungicide resistance. However, the current study investigating five fludioxonil-resistant laboratory mutants found a significant fitness cost associated with fludioxonil resistance resulting in significantly (P < 0.05) reduced mycelial growth and sclerotia formation on potato dextrose agar as well as significantly (P < 0.05) lower pathogenicity on detached tomato leaves, with one mutant, LK-1R, completely losing the capacity to cause infection. In addition, all of the fludioxonil-resistant mutants had significantly (P < 0.05) increased sensitivity to osmotic stress (0.5 M of potassium chloride and 1.0 M of glucose), which is consistent with the proposed fludioxonil target sites within the high osmolarity glycerol stress response mitogen-activated protein kinase (HOG1-MAPK) signaling transduction pathway. Sequence analysis of six genes from this two-component pathway, including SsHk, SsYpd, SsSk1, SsSk2, SsPbs, and SsHog, revealed several mutations that may be associated with fludioxonil resistance. For example, six separate point mutations were found in SsHk that led to changes in the predicted amino acid sequence, including A136G, F249V, G353A, E560K, M610K, and K727R. Similarly, SsPbs had three mutations (D34G, S46L, and L337E), SsSk1 and SsYpd had two (S53G and A795V for SsSk1, and E67G and Y141H for SsYpd), and SsHog and SsSk2 had one each (V220A and S763P, respectively). To our knowledge, these constitute the first reports of amino acid changes in proteins of the HOG1-MAPK pathway being associated with fludioxonil resistance in S. sclerotiorum. This study also showed a positive cross-resistance between fludioxonil and dimethachlone and procymidone, but none with tebuconazole or carbendazim, indicating that the inclusion of tebuconazole within an integrated pest management program could reduce the risk of fludioxonil resistance developing in field populations of S. sclerotiorum and ensure the sustainable production of soybeans in China into the future.

Abstract
Objective: To investigate the status and influencing factors of skin cleaning outside wound (hereinafter referred to as skin) in adult trauma patients. Methods: A multicenter cross-sectional investigation was conducted. From September 1 to 30, 2020, a total of 952 adult trauma patients who met the inclusion criteria were admitted to wound care clinics or trauma surgery wards of 13 military or local Grade Ⅲ Level A hospitals, including the General Hospital of the Eastern Theater Command of People's Liberation Army and the Army Medical Center, etc. A self-designed questionnaire on cleaning status of skin in trauma patients was released through the "questionnaire star" website to investigate basic information such as gender, age, education level, living status, and self-care ability, trauma information such as cause of injury, wound duration, trauma site, trauma depth, wound pain, wound peculiar smell, and wound cleaning solution, and skin cleaning status after injury such as whether to clean or not, cleaning method, cleaning frequency, cleaning duration in each time, or reasons for not cleaning. The patients who cleaned skin regularly after injury were included in cleaning group, and the other patients were included in no cleaning group. The basic information, trauma information, and skin cleaning status after injury of patients in 2 groups were investigated. Data were statistically analyzed with chi-square test, and binary multivariate logistic regression analysis was performed on indicators with statistically significant differences between the two groups to screen the independent influencing factors of skin cleaning in trauma patients. Results: A total of 952 questionnaires were received, and the recovery rate was 100%. Three invalid questionnaires were eliminated, and 949 valid questionnaires were obtained, with an effective rate of 99.68%. In 949 patients, there were 461 (48.6%) males and 488 (51.4%) females, aged 18-100 (50±18) years. Most patients were less than 60 years old, lived with their families, and could take care of themselves completely. Nearly half of the patients were with junior high school or below education level. The main causes of injury were sharp cutting injury and falling injury, the wound duration was 2-365 days, most of the injured parts were limbs and trunk, the wound depth was mostly full-thickness injury, and most patients had wound-related pain and no peculiar smell and used 5 g/L iodophor to clean the wound. Totally 684 (72.1%) patients cleaned their skin after injury, mainly by scrubbing with warm water, the cleaning frequency was mainly once or twice a week, and the cleaning time was mainly 10 or 15 min for each time. Totally 265 (27.9%) patients didn't clean their skin after injury, and the main causes for not cleaning were following the doctor's advice, followed by worrying about wound infection and loss of self-care ability. There were significantly statistical differences in constituent ratios of education level, self-care ability, cause of injury, wound pain, and wound peculiar smell of patients in 2 groups (χ2=12.365, 24.519, 22.820, 9.572, 92.342, P<0.01). Education level, self-care ability, cause of injury, wound pain, and wound peculiar smell were potential influencing factors of skin cleaning in patients. Binary multivariate logistic regression analysis showed that self-care ability, wound pain, and wound peculiar smell were independent influencing factors of skin cleaning in patients (odds ratio=1.51, 0.52, 3.72, 95% confidence interval=1.08-2.12, 0.42-0.89, 2.66-5.22, P<0.05 or P<0.01). Conclusions: Self-care ability, wound pain, and wound peculiar smell are independent influencing factors of skin cleaning in adult trauma patients.

Abstract
Objective: To investigate the clinical characteristics, treatment and prognosis of optic neuropathy associated with varicella zoster virus (VZV). Methods: Five cases of optic neuropathy associated with VZV infection from Department of Neurology between January 1, 2014 and March 31, 2019 were retrospectively collected. The clinical manifestations, treatment and prognosis were analyzed. Results: There were 7 eyes involved in 5 cases, 3 cases (3/5) involved only one eye, and 2 cases (2/5) involved both optic nerves. During the follow-up time, no recurrence was found. Severe visual impairment occurred in 4 eyes (4/7) and non-severe visual impairment in 3 eyes (3/7). Visual acuity improved significantly in 1 eye (1/7), turned better in 2 eyes (2/7), and remained unchanged in 4 eyes (4/7). In acute phase, abnormal signals of optic nerve and/or sheath were observed on MR images. Case 3 received antiviral and hormone therapy on the second day after the onset of the disease, and the visual acuity recovered well; the other 4 cases had poor prognosis. Conclusions: Head and face VZV infection can cause serious optic neuropathy, leading to severe visual dysfunction, and poor prognosis, but recurrence is rare. Early intravenous administration of antiviral drugs (acyclovir is the best) and hormones are recommended for VZV infection in this area. It is best to use drugs within 72 hours in order to avoid and reduce secondary optic neuropathy as far as possible.

Abstract
Objective: To understand the causal relationship between sleep and coronary artery disease (CAD). Methods: This study included six genome-wide association parts; five for sleep related traits[sleep duration (continuous variable), long sleep duration (binary variable), short sleep duration (binary variable), early-to-bed/up habit (known as 'morningness') and frequently insomnia] and one for CAD. Heterogeneity in dependent instrument approach was used to assess and to remove the pleiotropic instruments. Generalized summary data-based Mendelian randomization was performed to estimate the causal relationships between sleep related traits and CAD. And a conservative Bonferroni was used for statistical tests. Results: Sleep duration was putatively causal for CAD (OR=0.755, 95%CI: 0.658-0.867, P=6.68E-05). Our results also indicated significant causal effects between both short sleep duration and frequently insomnia on CAD, with ORs as 4.251 (95%CI: 2.396-7.541, P=7.51E-07) and 1.814 (95%CI: 1.346-2.446, P=9.25E-05), respectively. There was no convincing evidence of causality between long sleep duration or morningness with CAD. Conclusions: Our findings suggested that both sleep duration and frequently insomnia played causal roles on CAD, indicating that disease models should include sleep duration and insomnia as potential factors for CAD to develop effective interventions.

Abstract
Objective: To characterize the ocular saccadic abnormality in neuromyelitis optica spectrum disorder (NMOSD) patients, and explore the relationship between ocular saccadic abnormality and the overall disability and visual function state. Methods: For the 110 consecutive NMOSD patients who visited the Department of Neurology of Beijing Tongren Hospital from July 2015 to July 2017, a 120 Hz spatial resolution infrared video nystagmus system was used to perform a quantitative horizontal saccade examination. All patients were assessed for overall disability status using the extended disability status scale (EDSS). The subjective visual function status was evaluated using the National Eye Institute-Visual Function Questionnaire (NEI-VFQ 25) and the 10-item neuro-ophthalmic supplement questionnaire (Suppl. 10). Results: A total of 68 (61.8%) of 110 NMOSD patients had horizontal saccadic abnormalities, including 50 cases (45.5%) with abnormal saccade latency, 34 cases (30.9%) with abnormal saccade accuracy and 22 cases (20.0%) with abnormal speed. Patients with abnormal saccade had more intracranial lesions and higher EDSS scores than those with normal eye movements (P=0.006 and P<0.001, respectively). Patients with abnormal saccade had lower Supp.10 scores than the normal patient (P=0.004), while there was no significant difference of NEI-VFQ 25 scores between the two groups (P=0.079). Conclusions: The horizontal saccadic abnormality is common in the NMOSD patients, and the overall disability status and visual function-related quality of life are worse. Quantitative horizontal saccade examination can provide important information on intracranial lesions and neuronal function impairment, and thus it should be emphasized in clinical settings.

Abstract
Objective: To investigate the clinical features, imaging findings and prognosis of idiopathic intracranial hypertension (IIH) patients complicated with iron deficiency anemia (IDA). Methods: A total of 307 cases of IIH patients hospitalized in Beijing Tongren Hospital were retrospectively screened between January 1, 2011 and February 28, 2018. There were 49 anemia cases (15.96%) and 45 IDA cases (14.66%), respectively. Finally, 36 IDA patients were enrolled. The clinical characteristics, imaging findings, treatment and prognosis of these patients were analyzed. Results: IIH combined with IDA was more common in women of childbearing age (34/36). There were 30 obese and overweight cases (83.33%), with multiple subacute or chronic course of disease. The visual symptoms in the early IIH patients were first diagnosed in the Department of Ophthalmology. The first symptom was headache with/without visual symptoms (27 cases (75%)). Head MRI detected empty sella or partial empty sella, and 2 cases of venous sinus thrombosis were found in DSA examination. Of the 34 female patients, 24 had simple menometrorrhagia or menstrual disorder. All patients were given methyl acetate to reduce the intracranial pressure and iron therapy. Five patients received low molecular weight heparin-warfarin sequential treatment, 5 cases underwent gynecologic surgery and 2 male cases received hemorrhoid operation. There were 7 cases underwent lumbar cisterna-peritoneal shunt for visual impairment. During the follow-up, intracranial pressure decreased and visual function of patients improved significantly. Conclusions: IIH is frequently found in obese or overweight women at childbearing age and IDA may be an important cause of IIH. IIH can cause serious irreversible visual impairment. Therefore, early identification and active treatment should be performed. Correction of anemia can significantly improve the clinical symptoms of IIH. Operation should be employed for IIH patients with poor visual function or rapid progress, in order to reduce intracranial pressure and improve prognosis as soon as possible.

Abstract
The development of periodontal tissue is a complex process, including cementoblast proliferation and differentiation. Emerging reports suggest that microRNAs (miRNAs) play crucial roles in gene regulatory networks governing numerous biological processes. However, how miRNAs modulate cementoblast proliferation and differentiation remains largely unknown. In a previous study, we performed miRNA microarray profiling to fully reveal the expression patterns of miRNAs involved in cementoblast differentiation. We focused on miR-361-3p, which decreased during cementoblast differentiation. Overexpression of miR-361-3p resulted in decreased cementoblast differentiation, whereas the functional inhibition of miR-361-3p yielded the opposite effect. The bioinformatics approach identified nuclear factor of activated T-cell 5 (Nfat5) as a potential target of miR-361-3p, which was further verified by dual luciferase assay. Meanwhile, the expression pattern of Nfat5 was verified both in vitro and in vivo. Furthermore, knockdown of Nfat5 mimicked the inhibitory effect of overexpressing miR-361-3p in cementoblasts. Moreover, multiple signaling pathways, including the Erk1/2, JNK, p38, PI3K-Akt, and NF-κB pathways, were notably activated, and the Wnt/ß-catenin pathway was blocked by downregulation of Nfat5 or forced expression of miR-361-3p in cementoblast differentiation. Finally, the complementary approach demonstrated that miR-361-3p regulated cementoblast differentiation via or partially via Erk1/2 and PI3K-Akt. Overall, our study elucidated that the JNK, p38, NF-κB, and Wnt/ß-catenin pathways act as balancing players in the miR-361-3p/Nfat5 signaling axis during cementoblast differentiation.

Abstract
OBJECTIVE To evaluate the differences of plaquecomposition and volume between symptomatic and asymptomatic patients with carotid artery stenosis by multi-detector computed tomography angiography (MDCTA). METHODS The consecutive patients with internal carotid artery stenosis≥70% diagnosed by digital subtraction angiography (DSA) were retrospectively analyzed from July 2011 to December 2015 in Peking University China-Japan Friendship School of Clinical Medicine. The symptomatic patients were defined as those who experienced nondisabling ischemic stroke or transient cerebralis chemic symptoms, including hemispheric events oramaurosis fugaxin the last 6 months. Otherwise, the patients were considered as a symptomatic. A total of 78 patients were enrolled in the study. Of these patients, there were 35 asymptomatic patients (44.9%) and 43 symptomatic patients (55.1%). All the patients received MDCTA before DSA. According to the plaque analysis of post processing work station, carotid plaques were divided into lipid-rich necrotic coreplaques (HU≤60), fibrous plaques (60 to 130 HU) and calcified plaques (HU≥130) through the different value sthreshold of HU. The plaque volume and proportion were all calculated. The differences between the two groups were compared by statistical methods. RESULTS The proportion of calcified plaques in asymptomatic patients was significantly higher than in symptomatic patients (t=2.760, P=0.007).And the proportion of LRNC plaqueswas lower than that in symptomatic patients (Z=2.009, P=0.044). There was statistical significance between the asymptomatic and symptomatic patients. Multivariate analysis showed that there was a positive correlation between the proportion of calcified plaques and asymptomatic carotid artery stenosis (OR=0.949; 95%CI: 0.915 to 0.985; P=0.005). The proportion of LRNC plaques showed a negative correlation with asymptomatic carotid artery stenosis (OR=1.068; 95%CI: 1.021 to 1.117; P=0.004). For the symptomatic patients, when the LRNC plaque proportion was greater than 30.3%, the specificity was 94.3%, and the sensitivity was 37.2%. There was no significant difference in plaque volume and fibrous plaque proportion in both groups. CONCLUSION Compared with symptomatic carotid plaques, the proportion of asymptomatic calcified plaques increased but the proportion of LRNC plaques decreased. Plaque LRNC 30.3% of the total volume may represent a clinically useful cutoff. For the patients with carotid artery stenosis, MDCTA may help noninvasively risk-stratify patients.

Abstract
Objective: To analyze the clinical and immunological characteristics of acute severe bilateral optic neuritis, and to explore the predictive factors of vision outcome and relapse so as to save visual function and avoid or alleviate vision disability. Methods: Forty-eight inpatients confirmed with acute severe bilateral optic neuritis from January 2013 to June 2015 were included and followed up. The clinical features, immunological findings, optic nerve imaging, visual function outcome and predictors of relapse were statistically analyzed. Results: Acute severe bilateral optic neuritis accounted for 7.3% of the total number of optic neuritis in the same period. There were 35 cases (72.9%) with monophasic course, and 13 cases (27.1%) with recurrence or other central nervous system involvement during the follow-up period; 11 (22.9%) in 48 patients with positive AQP4-IgG; AQP4-IgG-positive patients had a higher recurrence rate (P<0.001) and poorer visual function prognosis (P=0.034) than antibody-negative patients; the baseline visual acuity (P=0.004), early treatment response (P=0.012) and number of involved optic nerve segments (P=0.016) were associated with end point visual function. Positive AQP4-IgG(OR 13.486, 95% CI 1.971-16.263)and combining with other autoimmune antibodies (OR 5.591, 95% CI 1.502-15.621)were independently associated with relapse. Conclusions: Acute severe bilateral optic neuritis is not unusual and may cause blindness or visual disability. The positive rate of AQP4-IgG and the recurrence rate of the disease are low in our study. The necessity for long-term immunotherapy requires individual consideration. The baseline visual acuity, involved segment number of optic nerve and response to early treatment are associated with prognosis of visual function. Patients with AQP4-IgG positive and other autoimmune antibodies are easy to relapse. Whether the antibody-negative bilateral optic neuritis is a heterogeneous disease and the relationship with classic NMO or NMOSD deserve further research.

Abstract
Objective: To explored the clinical application of the three-dimensional finite element model of atlantoaxial complex fracture. Methods: A three-dimensional finite element model of cervical spine (FEM/intact) was established by software of Abaqus6.12.On the basis of this model, a three-dimensional finite element model of four types of atlantoaxial complex fracture was established: C(1) fracture (Jefferson)+ C(2) fracture (type Ⅱfracture), Jefferson+ C(2) fracture(type Ⅲfracture), Jefferson+ C(2) fracture(Hangman), Jefferson+ stable C(2) fracture (FEM/fracture). The range of motion under flexion, extension, lateral bending and axial rotation were measured and compared with the model of cervical spine. Results: The three-dimensional finite element model of four types of atlantoaxial complex fracture had the same similarity and profile.The range of motion (ROM) of different segments had different changes.Compared with those in the normal model, the ROM of C(0/1) and C(1/2) in C(1) combined Ⅱ odontoid fracture model in flexion/extension, lateral bending and rotation increased by 57.45%, 29.34%, 48.09% and 95.49%, 88.52%, 36.71%, respectively.The ROM of C(0/1) and C(1/2) in C(1) combined Ⅲodontoid fracture model in flexion/extension, lateral bending and rotation increased by 47.01%, 27.30%, 45.31% and 90.38%, 27.30%, 30.0%.The ROM of C(0/1) and C(1/2) in C(1) combined Hangman fracture model in flexion/extension, lateral bending and rotation increased by 32.68%, 79.34%, 77.62% and 60.53%, 81.20%, 21.48%, respectively.The ROM of C(0/1) and C(1/2) in C(1) combined axis fracture model in flexion/extension, lateral bending and rotation increased by 15.00%, 29.30%, 8.47% and 37.87%, 75.57%, 8.30%, respectively. Conclusions: The three-dimensional finite element model can be used to simulate the biomechanics of atlantoaxial complex fracture.The ROM of atlantoaxial complex fracture is larger than nomal model, which indicates that surgical treatment should be performed.

Abstract
OBJECTIVE To investigate the clinical effectiveness of polytheretherketone (PEEK) cages assisted anterior cervical discetomy and fusion (ACDF) to treat cervical spondylosis with sympathetic symptoms. METHODS Retrospective analysis was undertaken for 39 patients who were diagnosed as cervical spondylosis with sympathetic symptoms and underwent ACDF with PEEK cages. Radiographs obtained before surgery, after surgery, and at the final follow-up were assessed for quality of fusion. The following criteria were used for assessing radiographic success of fusion: (1) endplate obliterated with no lucent lines; (2) obliteration of disc space by bony trabeculae; (3) less than 2°of intervertebral motion or 2 mm of motion between the spinous processes at the operated segment on flexion-extension lateral radiographs. The sympathetic symptoms including vertigo, headache, tinnitus, nausea and vomiting, heart throb, hypomnesia and gastroenterological discomfort were scored by 20-point system preoperatively, 2 months postoperatively and at the final follow-up. The recovery rate and clinical satisfaction rate were also evaluated. Surgical complications were also assessed. RESULTS They were followed up for at least one year. The mean follow-up was 15.6 months. Radiographs of the cervical spine at the last follow-up revealed a solid fusion with no signs of a pseudoarthrosis in 36 cases. In two patients delayed union and bony fusion were achieved at the end of 9 and 11 months. Pseudoarthosis was found in 1 case but the patient had no symptoms. The score of sympathetic symptoms before surgery, 2 months after surgery and at the final follow-up were 8.4±1.0,2.2±0.3,and 2.4±0.3, respectively. There were 22 excellent cases, 15 good cases, 1 fair case and 1 bad case in terms of RR. Good to excellent results were attained in 95% of theses patients. The sympathetic symptoms improved in all the patients and the score was significantly improved after surgery. There was one patient who had cerebral spinal fluid leakage but he recovered one week after surgery. Two patients felt a mild swallowing discomfort, but it disappeared within one month after surgery. Subcutaneous hematoma occurred in one patient due to obstructed drainage. It was cleared two days after surgery. CONCLUSION Cervical spondylosis patients with sympathetic symptoms may be managed successfully with ACDF using PEEK cages. Successful clinical results regarding symptom improvement and general satisfaction with the surgical procedure depend not only on obtaining successful decompression and radiographic fusion but also on patient selection.

Abstract
Objective: To explore the thermal damage to epithelial cell adhesion molecule(EpCAM)-positive tumor cells by novel aptamer-guided magnetic nanoparticles(AptNPs). Methods: EpCAM aptamer SYL3C was connected to NPs via biotin-streptavidin reaction. The diameter of AptNPs were characterized by Dynamic Light Scattering(DLS). The binding feature of the aptamer to EpCAM-positive tumor cells was evaluated by Prussian blue dyeing. Thermal damage under alternative magnetic field was measured bylactate dehydrogenase (LDH). The apoptosis of EpCAM-positive tumor cells was detected by acridine orange/ethidium bromide (AO/EB) double staining. Results: The average size of AptNPs was 282 nm. Flow cytometry and Prussian blue dyeing showed that AptNPs exhibited strong binding to the EpCAM-positive tumor cells but not to the EpCAM-negative tumor cells. Moreover, when incubated with 1.5×10(8) AptNPs under alternative electromagnetic fieldfor 5 hours, the viability of EpCAM-positive HCT116 cells and A549 cells was 28.9% and 54.4%, respectively, significantly lower than 76.7% of EpCAM-negative HepG2 cells (P<0.05). Conclusions: AptNPs can improve the thermal damage to EpCAM-positive tumor cells, and may have potential utility in the development of tumor targeted therapy.

Abstract
OBJECTIVES The association between AS (asthma) and dental caries is controversial, while that between allergic rhinitis (AR) and caries has not been established. This study aimed to verify the relationship among AR, AS and dental caries. DESIGN Retrospective cohort study. SETTING Data from Health Insurance Database of the Taiwan's National Health Insurance Research Database. PARTICIPANTS Nine thousand and thirty-eight children born in 2004 were obtained. Their claims data were evaluated from birth to the age of 9 years. MAIN OUTCOME MEASURES The frequencies of clinical visits for dental caries were calculated for primary teeth (age 1-5) and for dental transitional period (age 6-9). Differences in the frequencies of clinical visits for caries in AR vs non-AR and AS vs non-AS children were compared. Correlation between AR, AS and caries frequencies was studied, and the influences of AR drugs on the development of caries were evaluated. RESULTS After adjusting for confounding factors and AS case, the frequencies of clinical visits for caries were higher in AR (increased by 13%-25% and P<.001 at different age periods). The AR frequencies significantly correlated with caries frequencies in children with AR. Different AR drugs also correlated with caries formation. After adjusting for confounding factors and AR case, there was no relationship between AS and caries in children. CONCLUSION Asthma is not associated with dental caries, but AR can increase the frequency of clinical visits for caries. Medications for AR may also play a role in caries formation. Thus, AR may be a risk factor for childhood dental caries.

Abstract
OBJECTIVE To evaluate the feasibility of transforaminal endoscopic nerve root decompression for degenerative lumbar spinal stenosis (DLSS). METHODS From July 2011 to April 2016, 96 cases of single segment DLSS were involved. All the patients had unilateral lower extremity neurological symptoms, signs, neurogenic intermittent claudication of less than 500 m. Imaging examinations (CT or MRI) or diagnostic nerve root block confirmed single segment degeneration. The mean age was (71.6±5.4) years, male: 55 cases, female: 41 cases. Their intraoperative blood loss, operation time, complications, ambulation time and discharge time were recorded. Leg pain VAS, ODI were used to evaluate the pain and lumbar function of the patients. The clinical efficacy was evaluated by Nakai evaluation. RESULTS All the patients were performed endoscopic decompression of the lateral recess and nerve root by removing the ventral part of the superior facet joint, the ligamentum flavum and the intervertebral disc. The decompression range was from the inferior edge of the upper pedicle to the superior edge of the lower pedicle. The nerve root was detected to have no compression and the pulse of nerve root returned to normal. The patient got ambulant on the operation day and discharged if he had no discomfort symptom. In the study, 68 cases got follow up. The mean follow-up time was 12.1 months (6-63 months). The VAS at different follow-up time points was improved relative to the baseline, and the difference was statistically significant (F=491.60, P<0.001). The ODI at different follow-up time points was improved relative to the baseline, and the difference was statistically significant (F=189.91, P<0.001). The excellent and good rates of Nakai evaluation were 79.4% (excellent in 42 cases, good in 12 cases, fair in 10 cases and poor in 4 cases). The mean intraoperative blood loss was (49.29±11.86) mL. The mean operation time was (92.46±21.34) min. The mean ambulation time was 1.8 h. The mean discharge time was 2.3 days. Postoperative epidural hematoma was found in 1 case. Foot drop was found in 1 case. Second stage open surgery was performed in 6 cases. CONCLUSION We can apply transforaminal endoscopic decompression for the patients of lumbar spinal stenosis who have unilateral nerve root irritation. Patients with transforaminal endoscopic decompression can get less surgical trauma, quick recovery and obtain good short-term outcome.

Abstract
OBJECTIVE To describe the application of polymethylmethacrylate (PMMA) augmentation of cement-injectable cannulated pedicle screws for the treatment of degenerative lumbar scoliosis with osteoporosis. METHODS Retrospective cohort study was used to compare cement injectable cannulated pedicle screws (CICPs) group with PMMA augmentation and control group with traditional method in the correction surgery for Lenke-silva level III and level IV degenerative scoliosis cases with osteoporosis. Both groups were followed up for 1 year. The clinical results were assessed by visual analog scale (VAS) of pain on lumbar and lower limbers, Oswestry disability index (ODI) score and EuroQol-5 dimensions (EQ-5D) score. The coronal major curve Cobb angel in coronal plane and thoracic kyphosis Cobb angle, lumbar lordosis Cobb angle and sagittal vertical axis (SVA) in sagittal plane were tested in whole long spine X ray. The fusion rates were evaluated by lumbar X ray and dynamic X ray. RESULTS In this study 34 cases were enrolled, 15 cases in CICPs group and 19 cases in control group. The general characteristics including age, gender, weight, height, BMI and BMD were without statistical difference between the two groups. There were (5.7±2.2)PMMA augmentation screws in CICPs group. The operation time, blood loss and blood transfusion were higher in CICPs group than in control group, but without statistical difference. Lumbar VAS, lower limbers VAS, ODI score and EQ-5D were all better in 1 month postoperation, 6 months postoperation and 1 year postoperation than in preoperation in both groups. lumbar VAS scores of CICPs group in 6 months postoperation (CICPs group 3.1±1.3 vs. control group 4.4±1.4, P<0.01) together with lumbar VAS scores (CICPs group 3.3±1.0 vs. control group 5.2±1.4, P<0.01), ODI scores (CICPs group 22.7±17.2 vs. control group 31.4±18.5, P<0.01) and EQ-5D in 1 year postoperation (CICPs group 2.9±2.0 vs. control group 3.5±2.5, P<0.01)were lower than those of control group. The coronal major curve Cobb angels were all lower in 1 month postoperation, 6 months postoperation and 1 year postoperation than in preoperation in both groups; thoracic kyphosis Cobb angle and lumbar lordosis Cobb angle were all higher in 1 month postoperation, 6 months postoperation and 1 year postoperation than in preoperation in both groups. The coronal major curve Cobb angel was lower in CICPs group than that in control group in 1 year postoperation (CICPs group 17.6°±6.9° vs. control group 21.2°±7.2°, P<0.01)and thoracic kyphosis Cobb angle was higher in CICPs group than that in control group in 6 months postoperation (CICPs group -33.5°±8.8 ° vs. control group -28.9°±8.3°, P<0.01) and 1 year postoperation (CICPs group -33.0°±8.1° vs. control group -26.3°±7.4°, P<0.01) together with lumbar lordosis Cobb angle were higher in CICPs group than that in control group in 1 year postoperation (CICPs group 26.4°±8.1° vs. control group 22.1°±7.3°, P<0.01). CONCLUSION Polymethylmethacrylate augmentation of bone cement-injectable cannulated pedicle screws for the treatment of degenerative lumbar scoliosis with osteoporosis was effective and safe, the short-term clinical result was good.

Abstract
OBJECTIVE To describe the application of polymethylmethacrylate augmentation of bone cement-injectable cannulated pedicle screws for the treatment of degenerative lumbar diseases with osteoporosis. METHODS Observation group included 14 cases of degenerative lumbar diseases with osteoporosis received polymethylmethacrylate augmentation of bone cement-injectable cannulated pedicle screws from November 2014 to July 2015, control group included 12 cases of degenerative lumbar diseases with osteoporosis received polymethylmethacrylate augmentation with traditional pedicle screws.The operation time, blood loss, number of pedicle screws and number of augmented pedicle screws in the two groups were compared. The bone cement leakage and pulmonary bone cement embolism in the two groups were also compared. The fusion rate and pedicle screws loosening by lumbar X ray and dynamic X ray were evaluated. The clinical results were assessed by visual analog scale (VAS) of pain on lumbar and lower limbers, lumbar Japanese Orthopaedic Association scores (JOA), Prolo functional scores and Oswestry disability (ODI) scores. RESULTS Differences of operation time and blood loss in the two groups were not statistically significant. The average number of pedicle screws was 9.9±4.7 and the average number of augmented pedicle screws was 5.9±2.6 in observation group while the average number of pedicle screws was 7.1±2.8 and the average number of augmented pedicle screws was 3.0±1.9 in control group. The ratio of augmented pedicle screws was higher in observation group than in control group (0.69±0.30 vs.0.47±0.30,P<0.05). The bone cement leakage rate was lower in observation group than in control group (5/83 vs. 12/42, P<0.01). All the cases in observation group were without leakage to the interspinal canal while one case in control group suffered from bone cement leakage to the interspinal canal with augmentation of 3 pedicle screws. The follow up period was (10.6±2.3) months in observation group and (36.5±7.2) months in control group. In final follow up, no case with non-fusion or pedicle screws loosening was found in both groups. Lumbar VAS, lower limbers VAS, lumbar JOA scores, Prolo functional scores and ODI scores were all better than pre-operation (P<0.01). CONCLUSION Polymethylmethacrylate augmentation of bone cement-injectable cannulated pedicle screws for the treatment of degenerative lumbar diseases with osteoporosis was effective, with simple working processes and lower risk of bone cement leakage. The short-term clinical result was good.

Abstract
Buffalo are characteristic livestock of the Guangxi Zhuang Autonomous Region of China, but their low reproductive capacity necessitates the use of somatic cell nuclear transfer (SCNT). We investigated the effects of RG108 on DNA methylation in buffalo adult fibroblasts, and on subsequent SCNT embryo development. RG108 treatment (0, 5, 10, 20, and 100 mM) had no effect on cell morphology, viability, or karyotype (2n = 48), and cell growth followed a typical "S" curve. Immunohistochemistry showed that relative DNA methylation gradually decreased as RG108 concentration increased, and was significantly lower in the 20 and 100 mM groups compared to the 0, 5, and 10 mM treatments (0.94 ± 0.03 and 0.92 ± 0.05 vs 1.0 ± 0.02, 0.98 ± 0.05, and 0.98 ± 0.09, respectively; P < 0.05). Quantitative polymerase chain reaction revealed that DNMT1 gene expression of fibroblasts administered 10, 20, and 100 mM RG108 was significantly lower than those in the 0 and 5 mM groups (0.2 ± 0.05, 0.18 ± 0.07, and 0.3 ± 0.09 vs 1.0 ± 0.12 and 1.4 ± 0.12, respectively; P < 0.05). Treatment with 20 mM RG108 resulted in the lowest expression levels. Fibroblasts incubated with 20 mM RG108 for 72 h were used as donor cells to generate SCNT embryos. A greater number of such embryos developed into blastocysts compared to the non-treated group (28.9 ± 3.9 vs 15.3 ± 3.4%; P < 0.05). RG108 treatment can modify DNA methylation in buffalo adult fibroblasts and promote development of subsequent SCNT embryos.

Abstract
MicroRNA-9 (miR-9) has a well-established role in various tumors; the clinical significance and potential mechanism of miR-9 in human osteosarcoma (OS) has not been elucidated. The aim of this study was to investigate the mechanism and role of miR-9 expression in osteosarcoma cells. miR-9 expression in the OS cell line MG-63 and OS tissues was compared to that in a human osteoblastic cell line (hFOB 1.19) and adjacent normal tissues, respectively, by reverse transcriptase-polymerase chain reaction. miR-9 expression was downregulated by introducing small interfering RNA against miR-9 (si-miR-9) into the cells, and the proliferative, migratory, and invasive capacities of si-miR-9-transfected MG-63 cells were compared to those of control MG-63 cells. miR-9 was significantly upregulated in OS tissues and cell lines compared to the corresponding non-cancerous bone tissues (P < 0.05) and human osteoblastic cell line (P < 0.05), respectively. Upregulated miR-9 expression was also associated with increased cell proliferation (P < 0.05), migration (P < 0.05), and invasion (P < 0.05), and decreased apoptotic ability (P < 0.05). These results suggest that miR-9 may play a pivotal role in tumorigenesis and tumor progression in osteosarcoma.

Abstract
OBJECTIVE To investigate the clinical characteristics of vertebral compression fracture (VCF) in glucocorticosteroid-induced osteoporosis (GIOP) and risk of vertebral refracture after percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP). METHODS In the study, 570 cases who received PVP or PKP as treatments of VCF from January 2010 to December 2013 were retrospective reviewed, of which 42 were GIOP and 21 were followed up as GIOP group, and the other 528 were primary osteoporosis and 391 were followed up, of which 84 were selected as Control group based on age and gender. The fracture location, ratio of single segment fracture and multiple segments fracture in the two groups were compared. In the final follow up, the reoperation rates for vertebral refractures by the Kaplan-Meier method in the two groups were compared. RESULTS The follow up periods were (24.0± 13.1) months in GIOP group and (25.8±14.4) months in control group(P>0.05). In GIOP group, there were 11 cases with one-segment fracture, 2 with two-segments fracture, 3 with three-segments fracture, 2 with four-segments fracture, 2 with five-segments fracture and 1 with eight-segments fracture. In Control group, there were 67 cases with one-segment fracture, 12 with two-segments fracture, 3 with three-segment fracture, and 2 with four-segments fracture. The ratio of single segment fracture in GIOP group was significantly lower than that in Control group(52.4% vs. 79.8%,P=0.01). There were 50 fracture segments in GIOP group and 109 fracture segments in Control group. The ratios of fracture segments located in thoracic segments(T1-T10), thoracolumbar segments(T11-L1)and lumbar segments(L2-L5)were 18%, 46% and 36% in GIOP group and 11.9%, 58.7% and 29.4% in Control group (P>0.05). The refracture rate in GIOP group was higher than that in control group (23.8% vs. 6.0%). The survival rate was lower in GIOP group than that in control group (P<0.01). CONCLUSION The predilection site of VCF was similar in GIOP and primary osteoporosis (thoracolumbar segments> thoracic segments> lumbar segments). The risk of multiple segments VCF was higher in GIOP than in primary osteoporosis. The risk of vertebral refractures after PVP or PKP was higher in GIOP than in primary osteoporosis.

Abstract
Bone morphogenetic protein 4 (BMP4) regulates skeletogenesis, osteoblastic differentiation, and the induction of hair follicles. Its protein-coding region contains a signal peptide, prodomain (which regulates post-translational synthesis), and a mature domain (which mediates gene function). Previous studies considered this gene to be conserved. By reanalyzing the coding region of BMP4 in 16 mammalian species, we found that the mature domain is conserved in mammals. A comparison of the putative amino acid sequence demonstrates that BMP4 is relatively conserved. Two domains in BMP4 are connected by a random coil. The protein conformation differs between the Muridae family and other species, which might be associated with the body type of the former group.

Abstract
BACKGROUND Sedentary behaviour is ubiquitous in modern society. Emerging studies have focused on the health consequences of sedentary behaviour, including colorectal cancer, but whether sedentary behaviour is associated with the risks of colon and rectal cancer remains unclear. No systematic reviews have applied quantitative techniques to independently compute summary risk estimates. We aimed to conduct a meta-analysis to investigate this issue. METHODS We searched PubMed, Embase, and Google Scholar databases up to May 2013 to identify cohort and case-control studies that evaluated the association between sedentary behaviour and colon or rectal cancer. A random-effect model was used to pool the results of included studies. Publication bias was assessed by using Begg's funnel plot. RESULTS Twenty-three studies with 63 reports were included in our meta-analysis. These groups included 4,324,462 participants (27,231 colon cancer cases and 13,813 rectal cancer cases). Sedentary behaviour was significantly associated with colon cancer (relative risk (RR): 1.30, 95% confidence interval (CI): 1.22-1.39) but did not have a statistically significant association with rectal cancer (RR 1.05, 95% CI, 0.98-1.13). Subgroup analyses suggested that the odds ratio (OR) of colon cancer was 1.46 (95% CI: 1.22-1.68) in the case-control studies, and the RR was 1.27 (95% CI: 1.18-1.36) in the cohort studies, the OR of rectal cancer was 1.06 (95% CI: 0.85-1.33) in the case-control studies, and the RR was 1.06 (95% CI, 1.01-1.12) in the cohort studies. CONCLUSION Sedentary behaviour is associated with an increased risk of colon cancer. Subgroup analyses suggest a positive association between sedentary behaviour and risk of rectal cancer in cohort studies. Reducing sedentary behaviour is potentially important for the prevention of colorectal cancer.

Abstract
It is widely known that prenatal stress (PS) exposure causes depression-like behaviour to offspring, as well as maladaptive responses including neurobiological and physiological changes. However, the underlying mechanism of PS induced juvenile-onset depression remains largely unravelled. The inadequacies of monoamine deficiency hypothesis, the emerging evidence of altered glutamate neurotransmission in mood disorders, as well as our previous studies inspired us to assess the potential role of glutamatergic system in the pathogenesis of juvenile depression. In this research, we examined the expression of phosphorylated GluR1 subunit of ionotropic receptor alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR), the Na+-dependent glutamate transporters excitatory amino acid transporter 2 (EAAT2) and EAAT3 in the hippocampus, striatum and frontal cortex of 1-month-old rat offspring after mid and late PS exposure. Prenatally stressed offspring rats showed significantly prolonged duration of immobility and shortened immobility latency in tail suspension test. We also detected that PS significantly altered the expression of glutamate receptor and glutamate transporters of these depressed rats. In brief, the changes of phosphorylated GluR1 subunit of AMPAR protein level in the hippocampus and frontal cortex, as well as markedly decreased EAAT2 mRNA expression in the hippocampus, striatum and frontal cortex and EAAT3 mRNA expression in the hippocampus of stressed rats were both observed. These results underpinned that glutamate receptors and glutamate transporters might be involved in the progress of depression-like behaviour in juvenile rat offspring induced by PS.

Abstract
Scavenger receptor A (SR-A) is the main receptor through which oxidized LDL (oxLDL) and advanced glycation end products get into the cells. The aim of the present study was to investigate the effect of an ACE inhibitor, perindopril, on the expression of SR-A in renal tubulointerstitium of diabetic rats. Diabetes was induced in male Sprague-Dawley rats by injection with streptozotocin. The rats were then randomly divided into 3 groups: normal control group; untreated diabetes mellitus group; and diabetes mellitus group treated with the ACE inhibitor, perindopril. After a 24-week treatment, tubulointerstitial injury index was assessed on Masson's trichrome sections. The number of macrophages and the expression of SR-A protein in renal tubulointerstitium were detected by immunohistochemistry and the expression of SR-A mRNA was detected by RT-PCR. The tubulointerstitial injury index, the number of macrophages and the expression of SR-A mRNA were significantly higher in the diabetes group than the normal control group. Perindopril treatment not only attenuated the tubulointerstitial injury and the macrophages infiltration but also reduced the overexpression of SR-A mRNA in diabetic rats. The expression of SR-A protein was most obvious in renal tubulointerstitium in diabetic rats, which was attenuated by perindopril treatment. The findings of the present study indicate that perindopril may have renoprotective effects of diabetic nephropathy via inhibiting the expression of SR-A in renal tubulointerstitium.

Abstract
AIMS Osteoprotegerin (OPG) is a recently identified inhibitor of bone resorption. Recent studies indicate that OPG is also associated with endothelial dysfunction in Type 2 diabetes. The aim was to investigate the relationship between plasma OPG levels and urinary albumin excretion (UAE) in Type 2 diabetic patients. METHODS This study included 154 newly diagnosed Type 2 diabetic patients and 46 healthy subjects. Plasma OPG and 24-h UAE were measured. High-resolution ultrasound was used to measure flow-mediated (endothelium-dependent arterial) dilation (FMD). RESULTS Compared with the normoalbuminuric subgroup, OPG levels in the microalbuminuric subgroup were significantly higher, and OPG levels in macroalbuminuria subgroup were significantly higher than those in the normoalbuminuria and albuminuria subgroups. Multiple regression analysis showed that only FMD (r = -0.26), C-reactive protein (r = 0.23), fasting blood glucose (r = 0.25), 2-h blood glucose (r = 0.21), HbA(1c) (r = 0.28), UAE (r = 0.27) and retinopathy (r = 0.27) were significant factors associated with OPG. Pearson's correlation analyses showed a positive correlation between OPG and logUAE (r = 0.440) and negative correlations between OPG and FMD (r = -0.284), and between FMD and logUAE (r = -0.602). CONCLUSIONS Plasma OPG levels are significantly associated with UAE in Type 2 diabetic patients.

Abstract
The catalytic hydrogenation of p-nitrophenol to p-aminophenol over nano-sized nickel catalysts was carried out in a submerged ceramic membrane reactor. It has been demonstrated that the submerged ceramic membrane reactor is more suitable for the p-nitrophenol hydrogenation over nano-sized nickel catalysts compared with the side-stream ceramic membrane reactor, and the membrane module configuration has a great influence on the reaction rate of p-nitrophenol hydrogenation and the membrane treating capacity. The deactivation of nano-sized nickel is mainly caused by the adsorption of impurity on the surface of nickel and the increase of oxidation degree of nickel.

Abstract
OBJECTIVE Previous studies showed that endothelium-dependent arterial dilation is impaired in first-degree relatives of type 2 diabetes in the fasting state. In the present study, we examined whether endothelial dysfunction occurs when acute hyperglycemia is induced by oral glucose loading in this cohort. PATIENTS AND METHODS This study included 32 normal glucose tolerant subjects. Of them, 17 with a family history (FH) of type 2 diabetic parents (FH+) and 15 with no first-degree relative with diabetes or coronary artery disease (FH-). The examination of vascular function was performed in fasting state and repeated 1 and 2 hours after a 75-g oral glucose loading by high resolution ultrasound. RESULTS Endothelium- dependent arterial dilation in FH+ group were significantly lower than those in FH- before and after oral glucose loading (5.12+/-0.61% vs 6.03+/-0.56%, fasting; 4.0+/-0.65% vs 5.70+/-0.42%, 1 h; 4.43+/-0.61% vs 5.82+/-0.67% 2 h, p<0.05 each). In FH+ group, endothelium-dependent arterial dilation decreased significantly at 60 min (4.0+/-0.65% vs 5.12+/-0.61%, p<0.01) and increased markedly from 60 min at 120 min (4.43+/-0.61% vs 4.0+/-0.65%, p<0.05), which was still significantly lower than baseline (4.43+/-0.61% vs 5.12+/-0.61%, p<0.01) . In FH- group, however, the arterial dilation did not differ significantly among the three time points (p 0.05). In multiple regression analysis, endothelium-dependent arterial dilation was significantly correlated to FH+(r=-0.302, p<0.01). In addition, endothelium-dependent arterial dilation showed a correlation with plasma glucose (r=-0.460, p<0.01) and TBARS (r=-0.382, p<0.01) during OGTT in FH+ subjects. CONCLUSION Significant endothelial dysfunction is present in the fasting state, hyperglycemia in response to oral glucose loading rapidly suppresses endothelium-dependent arterial dilation in FH+ subjects, probably through increased production of oxygen-derived free radicals.

Abstract
Reaction of 4,4'-dipyridine dioxide (dpdo) and CuCl(2).6H(2)O in aqueous solution gave an adduct [Cu(H(2)O)(6)]Cl(2).2dpdo.2H(2)O 1, which has a hydrogen-bonded three-dimensional network. While substituting CuCl(2).6H(2)O with Cu(ClO(4))(2).6H(2)O, three pseudopolymorphs, namely, [Cu(dpdo)(6)][ClO(4)](2) 2, [Cu(3)(dpdo)(8)(H(2)O)(6)][ClO(4)](6).2dpdo.6H(2)O 3, and [Cu(dpdo)(H(2)O)(4)][ClO(4)](2).2dpdo 4, were isolated. 2 consists of a mononuclear copper coordinated with six terminal dpdo ligands. Adjacent mononuclear units are overlapped through pi-pi stacking of pyridine rings to give a 2D sheet with a triangular channel. 3 forms a trinuclear cluster bridged by two dpdo molecules. The solvate and terminal dpdo molecules are interwoven through hydrogen bonding and pi-pi stacking to lead to a rectangular channel with a dimensionality of 12.98 A x 13.44 A. 4 has a one-dimensional chain structure bridged by dpdo. Two solvate dpdo ligands link these chains through hydrogen bonding to generate two sets of three-dimensional networks which are interwoven through a common conjunctive point [Cu(H(2)O)(4)](2+), yielding a three-dimensional open framework with triangular channels. ClO(4)(-) anions are included within these channels in 2-4 through weak C-H...O hydrogen bonding. The introduction of the second spacer, 4,4'-bipyridine, generated a 2D architecture [Cu(dpdo)(4,4'-bipy)][ClO(4)](2).2H(2)O.dpdo 5, which is constructed by 4,4'-bipy and 4,4'-dpdo simultaneously, exhibiting a large channel with approximate dimensionality 11.1 A x 12.6 A, in which solvate 4,4'-dpdo ligand and perchlorate anions are accommodated.

Abstract
OBJECTIVE To observe the effect of Xuejie Jiawei Decoction (XJJWD) in reducing vaginal hemorrhagic amount, shortening hemorrhagic duration and lowering the curettage rate of incomplete abortion in patients after drug-abortion. METHODS Group A was treated with XJJWD No. I from the 2nd day after abortion, one dose per day for 7 days. Group B was treated with XJJWD No. II from the 11th day after abortion, one dose per day for 5 days. The therapeutic effect of the two groups was compared with that of the untreated control group. RESULTS In the Group A, the total score on vaginal hemorrhagic amount was markedly less than that in the control group (P < 0.01), and the vaginal hemorrhagic duration in patients with menostasis less than 45 days was shorter than that in the control group (P < 0.01). In the Group B, the total score on vaginal hemorrhagic amount in patients with menostasis less than 45 days was lower than that in the control group (P < 0.05). CONCLUSION XJJWD could reduce the vaginal hemorrhagic amount and duration in patients after drug-abortion. It should be applied early after abortion, the less the duration of menostasis, the more effective the treatment.

Abstract
Eosinophilic gastroenteritis is rare in pediatric patients. The three main manifestations, defined by Klein et al. in 1970, were (a) predominant mucosal, (b) predominant muscular-layer, and (c) predominant subserosal disease. The predominant subserosal type is the rarest of the three. We report on a 43-month-old boy who, on admission, suffered from recurrent abdominal pain, vomiting and diarrhea for one week, with ascites and pleural effusion noted. The white blood cell (WBC) count of ascites fluid was 8,000/mm3, with a differential count of 99% eosinophils. The peripheral WBC count was 44,000/mm3, with 78% eosinophils. Three days after diagnosis, ascites, pleural effusion and other gastrointestinal symptoms were gradually relieved using steroid therapy, with the peripheral eosinophil count returning to normal. The steroid therapy was discontinued after two months with tapering dose. The boy was in good health with no recurrence of symptoms in a follow-up conducted after one year.

Abstract
House dust mite (HDM) is a common inhalant allergen which can precipitate atopic disease episodes including asthma and allergic rhinitis. However, the relationship between HDM and asthma in subtropical regions of Asia, which may be affected by differences in climate and environmental variables, has not been widely studied. To assess this relation in the subtropical region of central Taiwan, we collected HDM samples from the houses of eight asthmatic patients as well as four normal subjects over a 1-year period. HDMs were collected by vacuum from the following four areas: living room floor, sofa, the top surface of child's mattress and bedroom floor. The mite concentrations, site distribution, seasonal variation, individual species and correlation with asthmatic attacks were studied. The HDM concentration had a seasonal variation, with the highest concentrations noted from July to November with gradually decrease from December to June. Among the four areas of collection, the highest concentration of mites was found on the child's mattress (p < 0.05). Dermatophagoides pteronyssinus was the dominant species (77%) and Dermatophagoides farinae was the second (13%). Our data showed that: 1. The highest concentrations of HDM occurred during the period from July to November. 2. The child's mattress was the household region with the highest percentage of HDM and thus should be considered of great concern as a likely source of the exacerbation of asthma. 3. D. pteronyssinus was the dominant species.

Abstract
Objective. To analyze and study astronaut and his personal equipment safety. Method. Three of the most widely used approaches, failure mode and effect analysis (FMEA), fault tree analysis (FTA) and system hazards analysis (SHA) were used. Result. It was demonstrated that astronaut and the personal equipment are subjected to various potential hazards, such as human errors, astronaut illness, fire or space suit emergency decompression, etc. Their causes, mechanisms, possible effects and criticality of some critical potential hazards were analyzed and identified in more details with considerations of the historic accidents of manned spaceflight. And the compensating provisions and preventive measures for each hazard were discussed. Conclusion. The analysis study may be helpful in enhancing the safety of the astronaut and its personal protective equipment.
