Abstract
This review aims to provide a summary of the clinical characteristics and outcomes of lung cancer during pregnancy. A comprehensive literature search yielded 93 cases of lung cancer during pregnancy from 1953 to 2022, with an average maternal age of ∼34 years old. The initial symptoms reported were often nonspecific, such as cough, dyspnea, and chest pain. Cancer-related treatments, including surgery, radiotherapy, chemotherapy, and tyrosine kinase inhibitors, have shown beneficial effects on maternal outcomes. A majority of the newborns were born without malformation or diseases, but extended follow-up remains necessary. Early diagnosis of lung cancer is imperative for reducing the risks of placental and fetal metastasis and enhancing overall survival.

Abstract
Obstructive sleep apnoea (OSA)-induced chronic intermittent hypoxia (CIH) has been considered a risk factor for severe asthma. Airway remodelling, which could be modulated by autophagy, plays a key role in severe asthma. However, the extent of autophagy's involvement in CIH-potentiated airway remodelling remains largely unexplored. Furthermore, we had found that angiotensin-(1-7) [Ang-(1-7)] has therapeutic effects on airway remodelling in asthma, but the underlying mechanism is either unclear. This study aimed to explore how CIH aggravates asthma and mechanism of protective effects of Ang-(1-7) on airway remodelling, with a focus on autophagy. We observed that CIH promoted epithelial-to-mesenchymal transition (EMT), indicated by elevated EMT and fibrotic markers such as Snail and Collagen IV, both in vitro and in vivo. CIH intensified cell autophagy, evident from increased LC3B expression and reduced p62 levels. Ang-(1-7) reversed the CIH-enhanced expression of Snail, Collagen IV, and LC3B. To explore how CIH enhanced autophagy in cellular and animal model of asthma, overexpression of hypoxia-inducible factor 1-alpha (HIF-1α) and Thrombospondin 1 (THBS1) were identified in CIH-exposure mice lung compared with normal mice lung tissues from the GEO database. Finally, through chromatin immunoprecipitation and immunoprecipitation assays, we verified that Ang-(1-7) inhibits CIH-induced binding of HIF-1α to the promoter of THBS1, and also disrupts the protein-protein interaction between THBS1 and the autophagy-associated protein Beclin 1 (BECN1), ultimately leading to autophagy inhibition. Our findings suggest that exogenous Ang-(1-7) can inhibit autophagy via HIF-1α/THBS1/BECN1 axis, thereby alleviating CIH-enhanced airway remodelling in asthma. These findings imply the potential therapeutic effect of Ang-(1-7) in asthma with OSA.

Abstract
BACKGROUND Anti-coagulation is the cornerstone management of acute pulmonary embolism (PE), which is a double-edged sword, as it increases the risk of bleeding. Thus, predicting bleeding risk is necessary. The liver produces most coagulation factors to maintain the coagulation balance. However, the association between liver dysfunction markers and bleeding risk has not been thoroughly investigated. METHODS A single-center, retrospective analysis of patients with acute PE was performed. First, the authors studied the association between liver dysfunction indexes and the 1-month bleeding risk. Then, they investigated whether it is more effective to predict the bleeding risk using a new joint model, i.e., adding liver dysfunction indexes to the PE-SARD score, which is the first score to assess the bleeding risk of acute PE. RESULTS Among 469 patients with acute PE, 34 patients (7.2%) had bleeding events within 1 month after the onset. The levels of aspartate aminotransferase (AST) were higher in the bleeding group compared with the non-bleeding group (36.0 [18.25-90.0] vs. 23.0 [18.0-31.0], p = 0.008). Compared with AST<40, the odds ratios of 80≤AST<120 and AST≥120 were significant (8.825 [2.449-31.804] and 8.023 [2.543-25.315] respectively, p<0.01), even when adjusted for nine confounding factors (p<0.05). The area under the curve of PE-SARD combined with AST was significantly higher than that of the PE-SARD score (p = 0.02). CONCLUSIONS In PE patients, AST is an independent factor in predicting the 1-month bleeding risk, and a novel joint model that combines AST and PE-SARD score improved the predictive efficiency for the 1-month bleeding risk.

Abstract
Purpose Sleep disturbance has been implicated in poor prognosis of coronavirus disease 2019 (COVID-19), but less is known about the influence of short sleep duration on COVID-19 outcomes. We aim to investigate whether short sleep duration is associated with prolonged virus shedding duration in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron-infected patients. Patients and Methods A total of 270 patients with a laboratory confirmed COVID-19 diagnosis during SARS-CoV-2 Omicron-predominant period were recruited. Self-reported sleep duration of the patients was collected. The two-way analysis of variance (ANOVA) was used to determine the interactions between sleep duration and variables, and multivariate logistic regression analysis was used to analyze the effect of independent variables on longer virus shedding duration. Results The two-way ANOVA revealed a significant sleep duration × snoring interaction effect for virus shedding duration, and a sleep duration × sex interaction effect for virus shedding duration. Multivariate logistic regression model illustrated that patients sleeping <6 h were at greater risk of prolonged virus shedding duration compared to those sleeping ≥6 hours (OR = 1.80, 95% CI = 1.01-3.26), independent of age, sex, co-existing diseases, vaccination condition, and antiviral treatment. Conclusion Short sleep duration (<6 h) was associated with increased virus shedding in SARS-CoV-2 Omicron-infected patients.

Abstract
Objective: To investigate the mutational features of the immunoglobulin heavy chain variable region (IgHV) gene in patients with chronic lymphocytic leukemia (CLL) using immunophenotypic and molecular genetic methods. Methods: The laboratory results of 266 CLL patients who underwent IgHV gene examination at Sino-US diagnostics laboratory from February 2020 to February 2021 were analyzed for the IgVH mutational status and presence of specific IgVH fragments. In addition, their immunophenotypic, molecular, chromosomal karyotypic, and FISH profiles were investigated and correlated with the IgVH mutational status. Results: Among 266 patients, 172 were male and 94 were female, with a media age of 67 years (20-82 years).There were more patients with mutated IgHV (m-IgHV) than unmutated IgHV (un-IgHV) (69.2%∶30.8%). There was association of VH family and the presence of gene fragments: the overall incidence of VH families including VH3 family (142/266, 53.4%), VH4 family (75/266, 28.2%), and VH1 family (34/266, 12.8%) was about 95%, among which the proportion of VH4-34 (26/266, 9.8%), VH3-23 (25/266, 9.4%), VH3-7 (24/266, 9.0%), and VH4-39 (16/266, 6.0%) was about 35%. VH3-20 and VH3-49 only occurred in un-IgHV (P<0.05). In addition, the expression rates of CD38 (26.3% vs. 3.0%), CD79b (71.1%∶45.5%) and 11q deletion (25.5%∶5.3%) were higher in un-IgHV, and single trisomy 12 (37.9%∶5.6%) were more commonly found in m-IgHV (P<0.05). MYD88 was one of the major mutation genes in m-IgHV, while ATM had the highest mutation rate in un-IgHV. Conclusion: CLL patients have differential expression in terms of IgHV gene mutations, correlating to their immunophenotype and genetics characteristics.

Abstract
Liposuction is not a risk-free procedure and potentially fatal complications may occur, especially liposuction-induced fat embolism syndrome (FES). Here we report the case of a 29-year-old woman who developed FES suddenly during a liposuction operation in a cosmetic medical clinic. She was transferred to the hospital and achieved complete recovery within 11 days by comprehensive therapeutic strategies, including noninvasive ventilation (NIV), corticosteroids, albumin, diuretics and anticoagulation. Liposuction-induced FES is a life-threatening condition, which can be treated with complate recovery by comprehensive therapeutic strategies according to its pathophysiologic mechanism.

Abstract
Background: Continuous positive airway pressure (CPAP) is the first-line therapy for moderate-to-severe obstructive sleep apnea (OSA). Specifying timing of CPAP benefits on OSA-related biomarkers will help to assess the effectiveness of CPAP and to optimize the treatment strategies. Purpose: To explore the time-dependent changes of circulating biomarkers to CPAP treatment in patients with OSA, including inflammatory biomarkers [C-reactive protein (CRP) and tumor necrosis factor–α (TNF-α)] and glycolipid metabolic biomarkers [fasting blood glucose (FBG), fasting insulin (FINS), low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), and triglyceride (TG)]. Methods: Searches of PubMed and Embase database were completed. Two independent reviewers extracted data from 68 included studies. A meta-analysis was conducted using a random-effect (or fixed-effect) model and standardized mean difference (SMD) model. The timing profiles of circulating biomarkers changes of inflammation and glycolipid metabolism were analyzed based on different CPAP duration, that is, short-term (<3 months), mid-term (3–6 months), and long-term (⩾6 months). Results: Those first improved by short-term treatment include CRP [SMD: 0.73, 95% confidence interval (CI): 0.15–1.31; p = 0.014], TNF-α [SMD: 0.48 (95% CI: 0.10–0.86; p = 0.014)], FBG [SMD: 0.32 (95% CI: 0.07–0.57; p = 0.011)], and LDL [SMD: 0.40 (95% CI: 0.18–0.62; p = 0.000)]. Those first improved by the mid-term or long-term treatment include HDL [SMD: –0.20 (95% CI: –0.36 to –0.03; p = 0.018)] and TC [SMD: 0.20 (95% CI: 0.05–0.34; p = 0.007)]. There were insignificant changes for TG and FINS after short or long CPAP. Conclusion: Our results imply that changes of circulating biomarkers for patients with OSA under CPAP treatment have a time-dependent profile.

Abstract
Objective: To analyze the genetic landscape of 52 fusion genes in patients with de novo acute lymphoblastic leukemia (ALL) and to investigate the characteristics of other laboratory results. Methods: The fusion gene expression was retrospectively analyzed in the 1 994 patients with de novo ALL diagnosed from September 2016 to December 2020. In addition, their mutational, immunophenotypical and karyotypical profiles were investigated. Results: In the 1 994 patients with ALL, the median age was 12 years (from 15 days to 89 years). In the panel of targeted genes, 15 different types of fusion genes were detected in 884 patients (44.33%) and demonstrated a Power law distribution. The frequency of detectable fusion genes in B-cell ALL was significantly higher than that in T-cell ALL (48.48% vs 18.71%), and fusion genes were almost exclusively expressed in B-cell ALL or T-cell ALL. The number of fusion genes showed peaks at<1 year, 3-5 years and 35-44 years, respectively. More fusion genes were identified in children than in adults. MLL-FG was most frequently seen in infants and TEL-AML1 was most commonly seen in children, while BCR-ABL1 was dominant in adults. The majority of fusion gene mutations involved signaling pathway and the most frequent mutations were observed in NRAS and KRAS genes. The expression of early-stage B-cell antigens varied in B-cell ALL patients. The complex karyotypes were more common in BCR-ABL1 positive patients than others. Conclusion: The distribution of fusion genes in ALL patients differs by ages and cell lineages. It also corresponds to various gene mutations, immunophenotypes, and karyotypes.

Abstract
Epidemiologic studies have shown that the fine particulate matter 2.5 (PM2.5) exaggerates chronic airway inflammation involving in acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Surfactant proteins (SPs) decreases significantly related to airflow limitation and airway inflammation. However, how to restore the reduction of SPs levels in airway inflammation exposed to PM2.5 has not been well understood. In the present study, the SPs including SPA, SPB, SPC and SPD levels in bronchoalveolar lavage fluid (BALF) were detected from patients with stable COPD. Rats were exposed to cigarette smoke and PM2.5. After given with Surfaxin, the expression of SPs, protein kinase C (PKC) and tight junction protein (ZO-1) in lung tissue and the levels of C-reactive protein (CRP) and fibrinogen (FIB) in plasma was observed. The results showed that SPA, SPB and SPD were significantly lower than those of the control group (p < 0.01). PM2.5 aggravated smoking-induced airway inflammation and oxidative stress demonstrated by pathological changes of lung tissue and increased levels of CRP and PKC in vivo. PM2.5 decreased the expression of all the SPs and ZO-1, which could be significantly restored by Surfaxin. These findings indicate that Surfaxin protects the alveolar epithelium from PM2.5 in airway inflammation through increasing SPs.

Abstract
OBJECTIVES Obstructive sleep apnoea (OSA) has received much attention as a risk factor for perioperative complications and 68.5% of OSA patients remain undiagnosed before surgery. Faciocervical characteristics may screen OSA for Asians due to smaller upper airways compared with Caucasians. Thus, our study aimed to explore a machine-learning model to screen moderate to severe OSA based on faciocervical and anthropometric measurements. DESIGN A cross-sectional study. SETTING Data were collected from the Shanghai Jiao Tong University School of Medicine affiliated Ruijin Hospital between February 2019 and August 2020. PARTICIPANTS A total of 481 Chinese participants were included in the study. PRIMARY AND SECONDARY OUTCOME: (1) Identification of moderate to severe OSA with apnoea-hypopnoea index 15 events/hour and (2) Verification of the machine-learning model. RESULTS Sex-Age-Body mass index (BMI)-maximum Interincisal distance-ratio of Height to thyrosternum distance-neck Circumference-waist Circumference (SABIHC2) model was set up. The SABIHC2 model could screen moderate to severe OSA with an area under the curve (AUC)=0.832, the sensitivity of 0.916 and specificity of 0.749, and performed better than the STOP-BANG (snoring, tiredness, observed apnea, high blood pressure, BMI, age, neck circumference, and male gender) questionnaire, which showed AUC=0.631, the sensitivity of 0.487 and specificity of 0.772. Especially for asymptomatic patients (Epworth Sleepiness Scale <10), the SABIHC2 model demonstrated better predictive ability compared with the STOP-BANG questionnaire, with AUC (0.824 vs 0.530), sensitivity (0.892 vs 0.348) and specificity (0.755 vs 0.809). CONCLUSION The SABIHC2 machine-learning model provides a simple and accurate assessment of moderate to severe OSA in the Chinese population, especially for those without significant daytime sleepiness.

Abstract
Objective: To analyze the genetic landscape of multiple fusion genes in patients with de novo acute myeloid leukemia (AML) and investigate the characteristics of immunophenotypes and mutations. Methods: The results of multiple fusion genes from 4192 patients with de novo AML were retrospectively analyzed from 2016 to 2020. In addition, the immunophenotypical data and the mutational results from high-through put method were statistically investigated and correlated as well. Results: ①Among the 52 targets, 29 different types of fusion genes were detected in 1948 patients (46.47%) with AML, which demonstrated an "exponential distribution" . ② As the age increased, the number of patients with fusion gene increased first and then decreased gradually. The total incidence rate of fusion genes and MLL rearrangment in children were significantly higher than those in adults (69.18% vs 44.76%, 15.35% vs 8.36%) . ③The mutations involving FLT3 and RAS signaling pathway contributed most in patients with MLL rearrangment. ④No specific immunophenotypic characteristics were found in AML patients with MLL or NUP98 rearrangements. Conclusion: Nearly half of AML patients were accompanied by specific fusion gene expression, the proportions of different fusion genes in pediatric and adults patients were different by multiple PCR. The gene mutations and immunophenotype of these AML patients have certain rules.

Abstract
Oxidative stress and inflammation induced by chronic intermittent hypoxia (CIH) are trigger factors of cardiovascular diseases in patients with obstructive sleep apnea (OSA). This study aimed to investigate the role of CIH-induced mitochondrial dysfunction in vascular endothelial injury both in vivo and in vitro. Human umbilical vein endothelial cells and Sprague Dawley rats were exposed to CIH. CIH promoted the production of intracellular reactive oxygen species, caused mitochondrial dysfunction, and induced cell apoptosis in human umbilical vein endothelial cells. RNA-Seq analysis revealed that the NOD-like receptor signaling pathway was involved in endothelial injury induced by CIH. TXNIP/NLRP3/IL-1β pathway was found to be upregulated by CIH. Knock-down of TNXIP rescued the endothelial cells from CIH-induced apoptosis, indicating that activation of the TXNIP/NLRP3/IL-1β pathway mediated the CIH-induced endothelial apoptosis. Administration of the mitochondria-targeted antioxidant mito-TEMPO improved mitochondrial function and suppressed upregulation of the TXNIP/NLRP3/IL-1β pathway, thereby alleviating CIH-induced endothelial apoptosis. In vivo experiments confirmed the results, where mito-TEMPO was found to ameliorate endothelial injury in rat aortas exposed to CIH. The results imply that CIH-induced mitochondrial dysfunction mediates endothelial injury implication of TXNIP/NLRP3/IL-1β signaling pathway.

Abstract
Noxious particulate matter in the air is a primary cause of chronic obstructive pulmonary disease (COPD). The bronchial tree acts to filter these materials in the air and preserve the integrity of the bronchi. Accumulating evidence has demonstrated that smoking and air pollutants are the most prominent risk factors of COPD. Bifurcations in the airway may act as deposition sites for the retention of inhaled particles, however, little is known concerning the impacts of abnormalities of the bronchial anatomy in the pathogenesis of COPD. Studies have reported significant associations between bronchial variations and the symptoms in COPD. In particular, it has been shown that bronchial variations in the central airway tree may contribute to the development of COPD. In this review, we identified three common types of bronchial variation that were used to formulate a unifying hypothesis to explain how bronchial variations contribute to the development of COPD. We also investigated the current evidence for the involvement of specific genes including fibroblast growth factor 10 (Fgf10) and bone morphogenetic protein 4 (Bmp4) in the formation of bronchial variation. Finally, we highlight novel assessment strategies and opportunities for future research of bronchial variations and genetic susceptibility in COPD and comorbidities. Our data strongly highlight the role of bronchial variations in the development, complications, and acute exacerbation of COPD.

Abstract
RATIONALE The incidence of nonsmall cell lung cancer (NSCLC) is high. Most nonsmall cell lung cancers have undergone multiple metastases at the time of initial diagnosis, and the 5 year survival rate is low. At present, comprehensive treatments, including systemic chemotherapy, targeted therapy, antiangiogenic therapy, and immunotherapy, prolong the survival of patients with advanced NSCLC. Herein, we report a case of NSCLC with long-term survival. PATIENT CONCERNS A 61-year-old woman complained of dry cough and shortness of breath and visited our hospital in July 2011. Imaging examination revealed a left upper lung mass with multiple metastases to the liver, adrenal gland, and bone. DIAGNOSES Stage IVB (cT2aN3M1c) lung adenocarcinoma was diagnosed, with multiple metastases of the lymph nodes, liver, adrenal gland, and bone. INTERVENTIONS AND OUTCOMES The patient received systemic chemotherapy and epidermal growth factor receptor-tyrosine kinase inhibitor-targeted therapy, and has survived for more than 9 years. LESSONS The patient benefited from maintenance chemotherapy and epidermal growth factor receptor-tyrosine kinase inhibitor treatment and achieved long-term survival.

Abstract
Chronic obstructive pulmonary disease (COPD) is a major health burden worldwide. Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is characterized by worsening of patients' respiratory symptoms that requires a modification in medication. This event could accelerate disease progression and increase the risk of hospital admissions and mortality. Both insomnia and obstructive sleep apnea (OSA) are prevalent in patients with COPD, and are linked to increased susceptibility to AECOPD. Improper treatment of insomnia may increase the risk of adverse respiratory outcomes for patients with COPD, while effective continuous positive airway pressure (CPAP) treatment may reduce the risk of AECOPD and mortality in patients with overlap syndrome. Sleep disorders should be considered in clinical management for COPD.

Abstract
OBJECTIVE The carotid body (CB) is a major peripheral respiratory chemoreceptor. In patients with obstructive sleep apnea (OSA), high CB chemosensitivity (CBC) is associated with refractory hypertension and insulin resistance and known to further aggravate OSA. Thus, the identification of high CB (hCBC) among OSA patients is of clinical significance, but detection methods are still limited. Therefore, this study aimed to explore the association of CBC with OSA severity and to develop a simplified model that can identify patients with hCBC. METHODS In this cross-sectional study of subjects who underwent polysomnography (PSG), CBC was measured using the Dejours test. We defined hCBC as a decrease of >12% in respiratory rate (RR) after breathing of pure O2. The association of CBC with OSA severity was explored by logistic regression, and a model for identifying hCBC was constructed and confirmed using receiver operating characteristic analysis. RESULTS Patients with OSA (n=142) and individuals without OSA (n=38) were enrolled. CBC was higher in patients with OSA than in those without OSA (% decrease in RR, 15.2%±13.3% vs 9.1%±7.5%, P<0.05). Apnea-hypopnea index (AHI), fraction of apnea-hypopnea events in rapid-eye-movement sleep (Fevents-in-REM), and longest time of apnea (LTA) were associated with hCBC independently (odds ratio [OR]=1.048, OR=1.082, and OR=1.024 respectively; all P<0.05). The model for identifying hCBC allocated a score to each criterion according to its OR values, ie, 1 (LTA >48.4 s), 2 (AHI >15.7 events/hour), and 3 (Fevents-in-REM >12.7%). A score of 3 or greater indicated hCBC with a sensitivity of 79.4% and specificity of 88.2%. CONCLUSION High CBC is associated with the severity of OSA. A simplified scoring system based on clinical variables from PSG can be used to identify hCBC.

Abstract
Coronavirus disease 2019 (COVID-19) pandemic may exert adverse impacts on sleep among populations, which may raise awareness of the burden of sleep disturbance, and the demand of intervention strategies for different populations. We aimed to summarize the current evidence for the impacts of COVID-19 on sleep in patients with COVID-19, healthcare workers (HWs), and the general population. We searched PubMed and Embase for studies on the prevalence of sleep disturbance. Totally, 86 studies were included in the review, including 16 studies for COVID-19 patients, 34 studies for HWs, and 36 studies for the general population. The prevalence of sleep disturbance was 33.3%-84.7%, and 29.5-40% in hospitalized COVID-19 patients and discharged COVID-19 survivors, respectively. Physiologic and psychological traumatic effects of the infection may interact with environmental factors to increase the risk of sleep disturbance in COVID-19 patients. The prevalence of sleep disturbance was 18.4-84.7% in HWs, and the contributors mainly included high workloads and shift work, occupation-related factors, and psychological factors. The prevalence of sleep disturbance was 17.65-81% in the general population. Physiologic and social-psychological factors contributed to sleep disturbance of the general population during COVID-19 pandemic. In summary, the sleep disturbance was highly prevalent during COVID-19 pandemic. Specific health strategies should be implemented to tackle sleep disturbance.

Abstract
Obstructive sleep apnea (OSA) is regarded as an independent risk factor for hypertension. The possible mechanism includes oxidative stress, endothelial injury, sympathetic excitement, renin-angiotensin-aldosterone system activation, etc. Clinical studies have found that there is a high coexistence of OSA and primary aldosteronism in patients with hypertension and that elevated aldosterone levels are independently associated with OSA severity in resistant hypertension. The underlying mechanism is that aldosterone excess can exacerbate OSA through increasing overnight fluid shift and affecting the mass and function of upper airway muscles during the sleep period. Thus, a bidirectional influence between OSA and aldosterone exists and contributes to hypertension in OSA patients, especially resistant hypertension.

Abstract
Renin-angiotensin system (RAS) is involved in TGF-β-mediated epithelial-to-mesenchymal transition (EMT) and is responsible for airway remodeling in refractory asthma. Obstructive sleep apnea (OSA), which affects RAS activity, is a risk factor for refractory asthma. We aimed to investigate how chronic intermittent hypoxia (IH), the main pathophysiology of OSA, exacerbates asthma and whether Ang-(1-7) protects against chronic IH-induced airway remodeling in asthma. We exposed ovalbumin (OVA)-challenged asthma mice to chronic IH and observed that chronic IH aggravated airway inflammation and collagen deposit in OVA-challenged mice. Compared with the OVA group, the OVA + chronic IH group had a lower expression level of epithelial marker E-cadherin and higher expression levels of mesenchymal markers α-smooth muscle actin and collagen IV in airway epithelia, accompanied with activation of TGF-β/Smad pathway. These changes were reversed by the administration of Ang-(1-7). Consistently, Ang-(1-7) mitigated chronic IH-induced activation of TGF-β-mediated EMT in lipopolysaccharide-treated bronchial epithelial cells in a dose-dependent manner, which was blocked by Ang-(1-7)-specific Mas receptor antagonist A779. Taken together, Ang-(1-7) rescued chronic IH-aggravated TGF-β-mediated EMT to suppress airway remodeling, implying that RAS activity is involved in the mechanisms of OSA-related airway dysfunction in asthma. SIGNIFICANCE STATEMENT: OSA is a risk factor for refractory asthma. In this study, we aimed to explore the mechanisms of how OSA exacerbates refractory asthma. We found that chronic IH induces TGF-β-mediated EMT and aggravates airway collagen deposit. We also found that Ang-(1-7) erased the aggravation of TGF-β-mediated EMT and epithelial fibrosis upon chronic IH exposure. These findings provided new insights that the ACE2/Ang-(1-7)/Mas axis might be considered as a potential therapeutic target for patients with asthma and OSA.

Abstract
BACKGROUND Mechanical ventilation (MV) with positive end-expiratory pressure (PEEP) is commonly applied in patients with severe traumatic brain injury (sTBI). However, the individual responsiveness of intracranial pressure (ICP) to PEEP varies. Thus, identifying an indicator detecting ICP responsiveness to PEEP is of great significance. As central venous pressure (CVP) could act as an intermediary to transduce pressure from PEEP to ICP, we developed a new indicator, PICGap, representing the gap between baseline ICP and baseline CVP. The aim of the current study was to explore the relationship between PICGap and ICP responsiveness to PEEP. METHODS A total of 112 patients with sTBI undergoing MV were enrolled in this prospective cohort study. ICP, CVP, cerebral perfusion pressure (CPP), static compliance of the respiratory system (Cst), and end-tidal carbon dioxide pressure (PetCO2) were recorded at the initial (3 cmH2O) and adjusted (15 cmH2O) levels of PEEP. PICGap was assessed as baseline ICP - baseline CVP (when PEEP = 3 cmH2O). The patients were classified into the ICP responder and non-responder groups based on whether ICP increment with PEEP adjusted from 3 cmH2O to 15 cmH2O was greater than 20% of baseline ICP. The above parameters were compared between the two groups, and prediction of ICP responsiveness to PEEP adjustment was evaluated by receiver operating characteristic (ROC) curve analysis. RESULTS Compared with the non-responder group, the responder group had lower PICGap (1.63 ± 1.33 versus 6.56 ± 2.46 mmHg; p < 0.001), lower baseline ICP, and higher baseline CVP. ROC curve analysis suggested that PICGap was a stronger predictive indicator of ICP responsiveness to PEEP (AUC = 0.957, 95%CI 0.918-0.996; p < 0.001) compared with baseline ICP and baseline CVP, with favorable sensitivity (95.24, 95%CI 86.91-98.70%) and specificity (87.6, 95%CI 75.76-94.27%), at a cut off value of 2.5 mmHg. CONCLUSION The impact of PEEP on ICP depends on the gap between baseline ICP and baseline CVP, i.e. PICGap. In addition, PICGap is a potential predictor of ICP responsiveness to PEEP adjustment in patients with sTBI.

Abstract
Background Obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular disease (CVD), which is attributed to chronic intermittent hypoxia (CIH) induced inflammation. As a new inflammatory biomarker of CVD, monocyte to high-density lipoprotein cholesterol ratio (MHR) has received little attention in OSA studies to date. Therefore, we aimed to investigate the correlation between MHR and concomitant CVD in Chinese Han patients with OSA. Methods A total of 657 Chinese Han subjects (169 controls, 145 mild, 94 moderate, and 249 severe OSA) of both genders were enrolled in this cross-sectional study, with an average BMI of 32.35±6.56 kg/m2. The relationship between MHR and concomitant CVD in OSA patients was analyzed. Results The level of MHR was correlated positively with apnea-hypopnea index (AHI), while negatively with lowest SpO2 (P<0.01). Moreover, the MHR values were higher in OSA patients with CVD than those without CVD (17.64±7.16 vs. 12.73±5.06, P<0.001). Logistic regression analysis demonstrated that MHR is an independent predictor of CVD (OR =1.190, P<0.001). The ROC analysis indicated that the best cut-off value of MHR for predicting CVD in OSA patients was 15.364 (sensitivity 65.0%, specificity 74.4%), while its cutoff value for identifying CVD in severe OSA patients was 15.362 (sensitivity 67.3%, specificity 80.1%). Conclusions MHR is strongly correlated with the severity of OSA and the occurrence of CVD in OSA patients. As an easy and available test, MHR is expected to be a promising biomarker candidate in predicting CVD in Chinese Han patients with OSA.

Abstract
OBJECTIVE Few studies have addressed the effects of visfatin on skeletal muscle remodeling. The aim of the study was to investigate the effects of visfatin on the expressions of myosin heavy chain (MHC) and its isoforms, the major indicator of fiber types and contractile properties of skeletal muscle. MATERIALS AND METHODS Levels of MHC, MHC I, MHC IIa, MHC IIb, adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK), p-AMPK and forkhead box protein O1 (FOXO1) were tested in visfatin-treated C2C12 myotubes. C2C12 myotubes were treated with visfatin combined with AMPK inhibitor or AMPK activator to investigate the role of AMPK in visfatin-mediated MHC expression. FOXO1 was overexpressed or knocked down in C2C12 myotubes to explore the role of FOXO1 in visfatin-mediated MHC expression. RESULTS Compared with the vehicle group, treatment with 5 μg/ml visfatin increased the levels of total MHC and its isoforms, MHC I, MHC IIa and MHC IIb, by 1.93, 1.84, 1.80, and 1.92 folds, respectively (all p = 0,001). Visfatin suppressed AMPK phosphorylation and decreased FOXO1 expression in C2C12 myotubes. The effects of visfatin on MHC I and MHC IIa expression were canceled by AMPK activator AICAR. FOXO1 overexpression minimized the visfatin-induced upregulation of MHC I, MHC IIa and MHC IIb. The effect of AMPK activator AICAR on MHC and its isoforms expression was minimized by knockdown of FOXO1. CONCLUSIONS The findings revealed that visfatin promoted expressions of MHC and its isoforms in C2C12 myotubes via suppressing AMPK/FOXO1 signaling pathway.

Abstract
PURPOSE Chronic intermittent hypoxia (CIH) contributes to the increased risk of cardiovascular diseases in obstructive sleep apnea (OSA). We previously reported the anti-apoptotic effects of estradiol (E2) on IH-exposed human umbilical vein endothelial cells (HUVECs). Herein, we employed a proteomic analysis to elucidate the mechanisms of the protective effects of E2 under IH exposure. METHODS HUVECs were divided into three groups: control, IH, and IH+E2 group. Isobaric tags for relative and absolute quantification (iTRAQ) were performed to compare protein profiles among the groups. Some of the identified proteins were validated by Western blotting. RESULTS A total of 185 proteins were differentially expressed in the IH+E2 group compared to the IH group. Bioinformatics analysis indicated that the effects of E2 may be linked to the regulation of cellular stress response. Among the differentially expressed proteins, we identified that serine-protein kinase ataxia telangiectasia mutated (ATM) and its downstream target, cellular inhibitor of apoptosis protein 1 (c-IAP1), were up-regulated by E2. We also observed that E2 decreased the level of cleaved caspase-3 and inhibited cell apoptosis in IH-exposed HUVECs. The inhibition of ATM abolished the anti-apoptotic effect of E2. CONCLUSION The ATM-c-IAP1 pathway is involved in the cardioprotective effects of E2 in HUVECs exposed to IH.

Abstract
BACKGROUND Epidemiologic studies have shown the effect of air pollutants on acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, little is known regarding the dose-response relationship. This study aimed to investigate the cumulative effect of air pollutants on AECOPD. METHODS We collected 101 patients with AECOPD from November 2010 through August 2011 in Shanghai. Multiple logistic regression was used to estimate associations between air pollutants and AECOPD. Poisson regression was then applied to determine the cumulative effect of air pollutants including particulate matter 10 (PM10), PM2.5, nitrogen dioxide (NO2), sulphur dioxide (SO2) and ozone (O3) on AECOPD, of which the seasonal variation was further explored. RESULTS The monthly episodes of AECOPD were associated with the concentrations of PM2.5 (r=0.884, p<0.05) and NO2 (r=0.763, p<0.05). The cutoff value of PM2.5 and NO2 for predicting AECOPD was 83.0μg/m3 and 53.5μg/m3, respectively. It showed that per 10μg/m3 increment in PM2.5 increased the relative risks (RR) for AECOPD was 1.09 with 3days cumulative effect in cold season, whereas 7days in warm season. The RR for AECOPD for per 10μg/m3 increment in NO2 was 1.07, with a 5-day cumulative effect without seasonal variation. CONCLUSIONS High consecutive levels of PM2.5 and NO2 increase the risk of developing AECOPD. Cumulative effect of PM2.5 and NO2 appears before the exacerbation onset. These gradations were more evident in the PM2.5 during different seasons.

Abstract
Chronic intermittent hypoxia (IH) contributes to obstructive sleep apnea (OSA)-related cardiovascular diseases through increasing oxidative stress. It has been widely recognized that estradiol decreases the risk for cardiovascular disease, but the estrogen replacement therapy is limited for its side effects. Thioredoxin (Trx) and its endogenous inhibitor, thioredoxin-interacting protein (Txnip), are associated with the protective effect of estradiol in some conditions. In this study, we aimed to explore whether estradiol could protect against IH-induced vascular injury, and the possible effect of Trx-1/Txnip in this process. Forty-eight adult female C57/BL6J mice were randomly divided into 4 groups, ovariectomy combined with IH group, sham operation combined with IH group, IH group and the control group. The mice treated with IH for 8 hrs/day, and 28 days. IH induced the injury of aorta, and ovariectomized mice were more prone to the IH-induced aortic injury, with higher level of oxidative stress. In vitro, estradiol increased Trx-1 level, but decreased the level of Txnip and oxidative stress in human umbilical vein endothelial cells (HUVECs) treated with IH for 16 hrs. Knock-down of Txnip by specific siRNA rescued oxidative stress and apoptosis. In conclusion, estradiol protects against IH-induced vascular injury, partially through the regulation of Trx-1/Txnip pathway.

Abstract
Objective: To report a case of the pulmonary surfactant protein(SP) adenosine triphosphate-binding-cassette-A3 (ABCA3) gene mutations in infant congenital interstitial lung disease(ILD), and review the related literature, to investigate the relationships of ABCA3 gene mutation associated with ILD in infants. Method: A 6-months-old boy was hospitalized in the department of Pediatrics of the First Affiliated Hospital of Guangzhou Medical University. The clinical, radiological, histological information from transbronchial lung biopsy (TBLB) and genetic testing in this case was analyzed; 12 reports retrieved on literature search at Pubmed, OVID databases from 2004 to 2015 by using the ABCA3 as keyword were reviewed and analyzed. Result: (1)The patient, a 6-months-old boy, had progressive tachypnea and dyspnea since 4 months old. Physical examination on admission revealed respiratory rate of 78 times/min , heart rate of 187 times/min, SpO2 0.93(mask oxygen-inspiration with 6 L/min), scattered fine moist crackles could be heard over the both lungs, clubbing fingers were found. High-resolution computed tomography(HRCT) revealed diffuse ground-glass opacity, interlobular and intralobular septal thickening. Lung biopsies showed evidences of the alveolar cavity atelectatic changes and interstitial fibrosis. SP-A and SP-B were negative in immunohistochemical stainting. SP-related gene sequence analysis found that there was compound heterozygous missense mutation of ABCA3 gene in c. 1942A>G, c.2701-33G>C and c. 991-105C>A. (2)The review of related literature found that totally 12 cases were reported. The main manifestations were progressive tachypnea and dyspnea, age of onset was between birth and 4 years of age. The imaging characteristics of chest HRCT revealed diffuse infiltration or diffuse ground-glass pattern in the lung. PROGNOSIS 6 cases died, and 6 cases survived, including 4 cases with pulmonary function disturbance to different degrees; 12 cases had ABCA3 gene mutations, 9 cases had composite ABCA3 gene mutations, in 11 cases the mutation occured in the exon of coding region, in 1 case in the intron, 9 cases had heterozygous mutations, 3 cases had homozygous mutations. Conclusion: The main phenotypes of ABCA3 mutation associated with ILD were full term neonatal respiratory distress syndrome or progressive tachypnea or dyspnea unexplained in infants. The chest HRCT showed two diffuse pulmonary interstitial changes. ABCA3 mutation mainly was multi-site composite mutations and heterozygous mutations in the exon of coding region.

Abstract
Objective: To observe the efficacy and safety of recombinant tissue-type plasminogen activator (rtPA) intravenous thrombolysis (IVT) in the treatment of acute cerebral infarction with hyperdense middle cerebral artery sign (HMCAS). Methods: Acute cerebral infarction patients with HMCAS from July 2010 to November 2015 at the First Affiliated Hospital of Dalian Medical University were collected.These patients were divided into two groups depending on whether they received IVT or not.The Nation Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) were used to evaluate early and long-time therapeutic effects.Efficacy and safety were compared between the two groups. Results: A total of 93 patients were eligible for the analysis, with 45 cases in IVT group and 48 cases in non-IVT group.As time went by, NIHSS score in IVT group showed significant downward trend than the non-IVT group.The rate of patients with good outcome in IVT group was higher than that in non-IVT group (P<0.05). The rate of hemorrhage transformation (HT) in IVT group and non-IVT group was 35.6% (16/45) and 10.4% (11/48), respectively, and the difference was statistically significant (P<0.05). While no statistically significant difference was found about the rate of symptomatic intracranial hemorrhage (sICH) (8.9% vs 2.1%, P>0.05) and mortality (33.3% vs 27.1%, P>0.05) between these two groups.Logistic regression analysis identified relativity between IVT treatment and good outcome (P<0.05), hemorrhage transformation (P<0.05), rather than mortality (P>0.05). Conclusions: Intravenous thrombolysis with rt-PA is an effective and safe treatment for most acute ischemic stroke patients with HMCAS and can promote early neurologic improvement and significantly improve long-term functional prognosis.Although Ⅳ thrombolysis can increase the risk of overall HT, it does not add risk in sICH and mortality.

Abstract
OBJECTIVE To characterize the molecular profile in patients with Ph negative myeloproliferative neoplasms (MPN) by exploring 49 gene mutations. METHODS Targeted gene sequencing were performed to analyze 49 MPN-associated genes in 51 patients with Ph negative MPN, of which CARL (exon 9), NPM1 (exon 12) and CEBPA (TAD, BZIP domains) were investigated by using Sanger sequencing simultaneously, while FLT3-ITD was assessed by PCR method. RESULTS Mutations were detected in 73.5% (36/49) of genes, and the mutational rates of JAK2-V617F, CALR (exon 9) and MPL were 60.8%(31/51), 7.8%(4/51) and 7.8%(4/51) respectively, whereas the mutational rates of ASXL1, SETBP1, and SF3B1 were around 10%. In addition, 96.1% (49/51) of patients harbored at least one mutation, and more than half of the patients (52.9%, 27/51) possessed 3 or 4 gene mutations. The amount of gene mutations was significantly higher in patients with JAK2-V617F mutation than those without JAK2-V617F or CALR (exon 9) mutation (P<0.05). The last finding was that there was no statistically significant difference in the amount of mutations among four MPN subtypes (PV, ET, PMF, and MPN-U). CONCLUSION Most patients with Ph negative MPN possesses three or more gene mutations, with various mutational profiles.

Abstract
OBJECTIVES To observe the intravenous thrombolysis effect of rt-PA in different time windows of acute cerebral infarction with atrial fibrillation(AF). METHODS Acute cerebral infarction patients who accepted the intravenous thrombolysis treatment with AF from January 2012 to December 2015 were included.According to the time from onset to intravenous thrombolysis, patients were divided into two groups: thrombolysis within 3 h and thrombolysis between 3-4.5 h. The Nation Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) were used to evaluate early and long-time therapeutic effects. The incidence of hemorrhagic infarction(HI), parenchymal hemorrhage(PH) and symptomatic intracranial hemorrhage(sICH) after thrombolysis within 24 hours were observed in the two groups. RESULTS A total of 103 patients were included in the study, with 48 cases in thrombolysis within 3 h group and 55 cases in thrombolysis between 3-4.5 h group. After thrombolysis treatment, the 24-hour and 7-day NIHSS score of the two groups were significant lower than before treatment, and the difference was statistically significant(P<0.05). Compared between groups, 24-hour clinical efficacy of thrombolysis within 3 h group was better than that of thrombolysis between 3-4.5 h group, and the difference was statistically significant(P<0.05). There were no statistically significant differences between these two groups about 7-day and 90-day prognosis(P<0.05). The rate of PH in thrombolysis within 3 h group and thrombolysis between 3-4.5 h group is 6.3%(3/48) and 21.8%(12/55) individually, and the difference was statistically significant(P<0.05). While no statistically significant differences was found about the rate of HI(18.8% vs 32.7%, P>0.05) and sICH(8.3% vs 14.5%, P>0.05) between these two groups. CONCLUSIONS For patients of acute cerebral infarction with AF, intravenous thrombolytic therapy by rt-PA within 3 h may contribute to a greatly improvement in a short time. Thrombolysis between 3-4.5 h increase the incidence of PH, but do not increase the incidence of sICH. There are no statistically significant differences between these two groups about 90-day favorable prognosis, indicating that thrombolysis between 3-4.5 h is safe and effective for acute cerebral infarction patients with AF.

Abstract
Ruscogenin, a natural steroidal sapogenin, presents in both food and medicinal plants. It has been found to exert significant anti-inflammatory activities. Considering that activation of neutrophil is a key feature of inflammatory diseases, this study was performed to investigate the inhibitory effect of ruscogenin and its underlying mechanisms responsible for neutrophil activation. Ruscogenin displayed potent antioxidative effects against Formyl-Met-Leu-Phe (FMLP)-induced extra- and intracellular superoxide generation in mouse bone marrow neutrophils, with IC50 values of 1.07±0.32 μM and 1.77±0.46 μM, respectively. Phorbol myristate acetate (PMA)-elicited extra- and intracellular superoxide generation were also suppressed by ruscogenin, with IC50 values of 1.56±0.46 μM and 1.29±0.49 μM, respectively. However, ruscogenin showed weak inhibition in NaF-induced response. Inhibition of superoxide generation was mediated neither by a superoxide-scavenging ability nor by a cytotoxic effect. Furthermore, ruscogenin inhibited the membrane translocation of p47phox and p67phox. It reduced FMLP-induced phosphorylation of cytosolic phospholipase A2 (cPLA2) and p21-activated kinase (PAK). The cellular cyclic adenosine monophosphate (cAMP) levels and protein kinase A (PKA) expression were increased by ruscogenin. Moreover, ruscogenin inhibited phosphorylation of protein kinase B (Akt), p38 mitogen-activated protein kinase (p38MAPK), extracellular signal-regulated kinase 1 and 2 (ERK1/2), and c-Jun N-terminal kinase (JNK). In addition, the inhibitory effects of ruscogenin on superoxide production and the phosphorylation of Akt, p38MAPK, and ERK1/2 were reversed by PKA inhibitor (H89), suggesting a PKA-dependent mechanism. In summary, our data suggest that ruscogenin inhibits activation of neutrophil through cPLA2, PAK, Akt, MAPKs, cAMP, and PKA signaling pathways. Increased PKA activity is associated with suppression of the phosphorylation of Akt, p38MAPK, and ERK1/2 pathways.

Abstract
Cyprinid herpesvirus 3 (CyHV-3) is a highly contagious virus that causes significant morbidity and mortality in common carp Cyprinus carpio L. and considered to be one of the most important pathogens of koi and common carp worldwide. Cyprinid herpesvirus 3 infected consignments imported from East Asian and South-East Asian regions were identified during quarantine period in Singapore, and virus from a 2005 consignment was successfully isolated in koi fin cells. A combination of sequence analyses and duplex PCR were used to characterize 15 CyHV-3 isolates detected in koi consignments between 2005 and 2011. Sequence analyses of the enlarged 9/5, SphI-5 and TK gene regions identified both the Asian 1 (n = 11) and European 4 (n = 4) genotypes. Duplex PCR analysis of two variable marker regions between ORF29 and ORF30 (marker I) as well as ORF133 and its upstream region (marker II) revealed viruses of genotypes J (I++ II+ ), U/I (I-- II- ), an intermediate genotype (I++ II- ) and a novel genotype, I++ II+Δ , which was identified in viruses from seven different consignments. This novel genotype has a 13-bp deletion in marker II, while maintaining the I++ allele of marker I. The I++ II+Δ genotype may have emerged from East Asian and South-East Asian regions in recent years.

Abstract
OBJECTIVES Little is known about combined effect of obstructive sleep apnea (OSA) and chronic smoking on cognitive impairment. We aimed to determine whether smoking synergizes with OSA in deteriorating cognitive function and whether smoking cessation contributes to cognitive benefits. METHODS One hundred and eighteen male patients were enrolled in the study and asked to complete neurocognitive function tests including Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), clock drawing test (CDT), and verbal fluency test (VFT). Variables of those neurocognitive function tests were analyzed with two factors: OSA and smoking. RESULTS After adjustment of potential confounding factors, an OSA-by-smoking interaction was found in CDT-C scores and a main smoking effect were showed in MoCA scores. Smoking patients with OSA had the worst performance in the four tests compared with the other three groups (smoking patients without OSA, non-smoking patients with and without OSA). Ex-smokers with OSA tended to perform better than current smokers, but still worse than never-smokers with OSA in those tests. CONCLUSION The results suggested that the coexistence of OSA and chronic smoking resulted in more pronounced cognitive deficits than either factor along. Smoking cessation may benefit cognitive function to some extents in patients with OSA.

Abstract
BACKGROUND Patients with physical disabilities more often have median neuropathies of the wrist and more than 70% of wheelchair users are overweight or obese. AIM To explore the effects of body composition on the occurrence of distal median neuropathy and to search for the best probabilistic cutoff value of indicators to predict the likelihood of developing distal median neuropathy in patients with physical disabilities. DESIGN A prospective study. SETTING A 1-day annual physical checkup program for employees of a social welfare organization. POPULATION In total, 72 patients with a physical disability (mean age ± SD, 40.0 ± 8.8 years; 40 women). METHODS Using electrophysiologic testing to assess distal median nerve function and using a dual-energy X-ray absorptiometry examination to assess body composition. The formula for leg exercise burden index (EBI) was: leg EBI = body fat mass of both legs/lean tissue mass of both legs. RESULTS The risk of developing a low median sensory nerve conduction velocity in the wrist-to-palm segment (< 43 m/s) was greater for patients with a higher leg EBI, yielding an adjusted odds ratio of 6.88 (P < 0.005). The body mass index (BMI) and being a wheelchair user were predictors of developing long median distal motor latency (> 4 ms). Using receiver operating characteristic analyses, we determined that patients with a physical disability were likely to develop distal median sensory neuropathy if they had a leg EBI of ≥ 0.943 and were likely to develop distal median motor neuropathy if they had a BMI of ≥ 24.5 kg/m2. CONCLUSION The leg EBI is a predictor of having distal median sensory neuropathy among patients with a physical disability. CLINICAL REHABILITATION IMPACT The value of the leg EBI can be useful information for identifying risk of distal median sensory neuropathy in patients with a physical disability.

Abstract
Long-term exposure to intermittent hypoxia (IH), such as that occurring in association with sleep apnea, may result in systemic hypertension; however, the time course changes in arterial pressure, autonomic functions, and baroreflex sensitivity are still unclear. We investigated the changes in cardiovascular neural regulations during the development of chronic IH-induced hypertension in rats. Sprague-Dawley rats were exposed to repetitive 1.25-min cycles (30 s of N2 + 45 s of 21% O2) of IH or room air (RA) for 6 h/day during light phase (10 AM-4 PM) for 30 days. Arterial pressure was measured daily using the telemetry system during RA breathing. The mean arterial pressure (MAP) and interpulse interval (PPI) signals were then used to assess the autonomic functions and spontaneous baroreflex sensitivity by auto- and cross-spectral analysis, respectively. Stable MAP, low-frequency power of MAP (BLF), and low-frequency power (LF)-to-high frequency power (HF) ratio of PPI (LF/HF) were significantly higher in IH-exposed rats, compared with those of RA-exposed rats. Elevation of the MAP, BLF, LF/HF, and minute ventilation started 5 days after IH exposure and lasted until the end of the 30-day observation period. Additionally, IH-exposed rats had significant lower slope of MAP-PPI linear regression (under a successively descending and ascending) and magnitude of MAP-PPI transfer function (at frequency ranges of 0.06–0.6 Hz or 0.6–2.4 Hz) after IH exposure for 17 days. However, RA-exposed rats did not exhibit these changes. The results of this study indicate that chronic IH-induced hypertension is associated with a facilitation of cardiovascular sympathetic outflow and inhibition of baroreflex sensitivity in conscious rats.

METHODS The records of acute and traumatic cervical cord injury patients hospitalized from 1989 to 1997 were reviewed. All subjects received comprehensive rehabilitation programs during hospitalization. Their survival status at the end of follow-up was studied. RESULTS Forty-seven of 109 (43.1%) people with cervical cord injuries were 50 years or older at onset. Older patients were more frequently injured by minor falls, resulting in more incomplete quadriplegia. They also showed fewer spinal fractures, and more demonstrated associated spondylosis and ossification of the posterior longitudinal ligament. Eleven (10.2%) subjects were deceased, found by a linkage to a death registration database at the end of follow-up. The significant predictor of survival status at follow-up was older age at injury using Cox proportional hazards model. CONCLUSION Spinal cord injured patients had different injury patterns, demanding different preventative strategies. Those injured at older ages were at higher risk of mortality according to our study. SPONSORSHIP This study was supported in part by grants from the National Taiwan University Hospital (89S2005), Taipei, Taiwan.

Abstract
OBJECTIVE To investigate the skin permeation of puerarin and its phospholipid complex and compare the differences between their permeation rates and cumulative permeation amounts. METHOD Performing a test of permeation through the mouse skin in vitro in an improved Franz diffusion cell. RESULT The cumulative permeation amount of phospholipid complex was higher than that of puerarin in the first hour and then increased slowly, meanwhile the permeation rate of puerarin rose higher than that of the complex. CONCLUSION Phospholipid complex of puerarin can permeate through the mouse skin rapidly up to a certain amount in a short time, then begins to release drug slowly and lastingly.

Abstract
A sireniform infant presented with an uncommon osseous fusion of the lower limbs characterised by a fused femur, a partially fused tibia and sympus dipus with rudimentary digits and metatarsals. Associated abnormalities included sacral agenesis, a deformed pelvis, anorectal atresia, renal agenesis, cystic renal dysplasia, agenesis of the uterus and urinary bladder, ambiguous external genitalia, a single umbilical artery, a lumbosacral neural tube defect, and ventriculomegaly secondary to a Chiari II malformation. The pathogenesis of concurrent sirenomelia and neural tube defect is discussed.

Abstract
Primary retroperitoneal liposarcoma is a rare malignancy comprising about only 0.1% of all cancers. It produces nonspecific symptoms and is often extensive when diagnosed. In this report, we present a case of a 68-year-old female patient who had a 29-kg retroperitoneal liposarcoma. Her early symptoms--including vague digestive disturbances, increasing abdominal girth and an abdominal mass, and clinical examinations such as sonography and computed tomography scan led to a preoperative diagnosis of ovarian cancer, until surgical and pathologic confirmation. Gross, radical resection of the tumor was successfully performed, and provided the most effective primary therapeutic approach. Histopathology revealed a mixed-type liposarcoma, with metastasis to the appendix. A poor prognosis was expected. Postoperative periodic follow-up was started to monitor for early detection of recurrence.

Abstract
OBJECTIVE To determine the association of disease related HLA-DRB1 locus with disease severity and extraarticular features in Singaporean Chinese patients with rheumatoid arthritis (RA). METHODS 70 patients with RA and 80 controls were typed for HLA class II alleles by the polymerase chain reaction-sequence specific oligonucleotide probe method. RESULTS 56 patients (80%) had erosive disease; 51 were seropositive (73%), and 16 had extraarticular features (23%). Patients with HLA-DRB1*0405 had significantly higher prevalence of extraarticular features (43 vs 10%; p = 0.001) and erosions (93 vs 71%; p = 0.022) compared to those without the allele. There was also a greater frequency of seropositivity and joint surgery, and a higher number of second line agents used by patients with HLA-DRB1*0405 in comparison to those without, although the difference was not statistically significant. CONCLUSION HLA-DRB1*0405 is associated with the presence of extraarticular features and erosions in Singaporean Chinese patients with RA.
