Abstract
Objective: To understand the cognition on and status quo of influenza vaccination among all age groups in the survey areas from 6 provinces so as to explore the main factors related to influenza vaccination. Methods: A cross-sectional survey method was conducted to study the knowledge on influenza prevention and control, as well as on the status of influenza vaccination in Beijing, Inner Mongolia, Shanghai, Guangdong, Yunnan, and Gansu provinces through 12320 health hotline telephone with method of random number table in Mar-May 2018. The survey sample size was 9 438 respondents. Results: The survey response rate was 46.4%(10 045/21 658). A total of 10 045 respondents were surveyed. The awareness on flu-related knowledge "influenza is different from the common cold" was 75.3% (7 564/10 045), rate on "influenza virus will cause serious consequences" was 82.0% (8 241/10 045). The rate of health behavior such as frequent hand, washing hand, wearing masks and isolating themselves were 80.41% (7 936/9 873), 75.8% (7 506/9 899) and 73.6%(7 228/9 822) respectively when the influenza-like symptoms already started. The influenza vaccination rate in the past year was only 5.7% (570/10 037). Multivariate logistic analysis of influenza vaccination rate in the past year showed that respondents who were from Gansu province or Beijing, respondents occupations were as medical staff or full-time students, respondents who were living with more than 2 people at the same house, respondents who had had influenza symptoms without wearing masks, the influenza vaccination rates were higher in the past year. Conclusions: Rates regarding the awareness of influenza-related knowledge, health behavior when the influenza-related symptoms already started and having received the influenza vaccine vaccination in the past year should be further improved in the six provinces. Health education on influenza-related knowledge and vaccine vaccination should be strengthened, strategies including free vaccination are bound to be explored.

Abstract
Due to the huge consumption of caffeinated food, beverages and medicines around the world, caffeine has been considered as a most representative pharmaceutically active compound (PhAC) pollutant based on its high abundance in environment and its indicator property for anthropogenic inputs of PhACs to water bodies. This review analyzed the existing literature about the bioaccumulation and environmental risks of caffeine residues in non-target organisms. There are 6 studies which were published in the last 5 years have reported the distribution of caffeine in tissues of aquatic organisms including fishes, clams, macroalgae and other aquatic plants, suggesting bioaccumulation of caffeine in organisms. The maximum detected levels of caffeine residues in tissues ranged from 1.55 to 344.9 ng/g. Importantly, definitive evidences have been provided that environmentally relevant caffeine concentrations exert adverse impacts on aquatic species and terrestrial insects, which included lethality, decreasing general stress, inducing oxidative stress and lipid peroxidation, affecting energy reserves and metabolic activity, neurotoxic effects, affecting reproduction and development, etc. In view of the severity and potential adverse impacts of caffeine pollution in the environment, we proposed that caffeine should be considered as a high-priority environmentally hazardous PhAC pollutant, and it is necessary to implement an ecopharmacovigilance (EPV) program targeting caffeine to minimize its environmental load from a pharmacy perspective.

Pyrophosphate-fructose 6-phosphate 1-phosphotransferase (PFP1) regulates starch biosynthesis and seed development via heterotetramer formation in rice (Oryza sativa L.). PLANT BIOTECHNOLOGY JOURNAL 2020; 18:83-95.

Abstract
Pyrophosphate-fructose 6-phosphate 1-phosphotransferase (PFP1) reversibly converts fructose 6-phosphate and pyrophosphate to fructose 1, 6-bisphosphate and orthophosphate during glycolysis, and has diverse functions in plants. However, mechanisms underlying the regulation of starch metabolism by PFP1 remain elusive. This study addressed the function of PFP1 in rice floury endosperm and defective grain filling. Compared with the wild type, pfp1-3 exhibited remarkably low grain weight and starch content, significantly increased protein and lipid content, and altered starch physicochemical properties and changes in embryo development. Map-based cloning revealed that pfp1-3 is a novel allele and encodes the regulatory β-subunit of PFP1 (PFP1β). Measurement of nicotinamide adenine dinucleotide (NAD+) showed that mutation of PFP1β markedly decreased its enzyme activity. PFP1β and three of four putative catalytic α-subunits of PFP1, PFP1α1, PFP1α2, and PFP1α4, interacted with each other to form a heterotetramer. Additionally, PFP1β, PFP1α1 and PFP1α2 also formed homodimers. Furthermore, transcriptome analysis revealed that mutation of PFP1β significantly altered expression of many essential enzymes in starch biosynthesis pathways. Concentrations of multiple lipid and glycolytic intermediates and trehalose metabolites were elevated in pfp1-3 endosperm, indicating that PFP1 modulates endosperm metabolism, potentially through reversible adjustments to metabolic fluxes. Taken together, these findings provide new insights into seed endosperm development and starch biosynthesis and will help in the breeding of rice cultivars with higher grain yield and quality.

Abstract
Objective: To compare the efficacy and safety profiles of tiotropium/olodaterol with the mono-components in Chinese and total study population from TONADO trial. Methods: In the replicate, double-blind, parallel-group, active-controlled, randomized, 52-week, Phase Ⅲ TONADO studies (TONADO 1+2), patients received tiotropium/olodaterol, tiotropium, or olodaterol via the Respimat(®) Inhaler (Boehringer Ingelheim, Germany). Primary end points were forced expiratory volume in 1 second (FEV(1)) area under the curve from 0 to 3 hours (AUC(0-3h)) response and trough FEV(1) response, and St George's respiratory questionnaire (SGRQ) total score at 24 weeks. Adverse events were also collected. This subgroup analysis only focused on the efficacy and safety of the drug at the approved dose in China. Results: 548 Chinese patients were randomized, aged 41 to 82 years [mean age, (63±8) years] and most were male (526, 96%), 111 received tiotropium/olodaterol 5/5 μg, and 127 received tiotropium 5 μg and 95 received olodaterol 5 μg. The baseline characteristics of these groups were similar. After 24 weeks, treatment with tiotropium/olodaterol 5/5 μg, tiotropium 5 μg and olodaterol 5 μg resulted in an adjusted mean FEV(1) AUC(0-3h) response of 0.240, 0.157 and 0.079 L, and trough FEV(1) response of 0.117, 0.068 and-0.001 L, respectively. Tiotropium/olodaterol 5/5 μg significantly improved SGRQ scores in Chinese patients compared with olodaterol 5 μg (32.729 and 37.202, respectively). Generally, the safety profile of tiotropium/olodaterol was comparable with mono-components in 52 weeks. Conclusion: Compared with tiotropium or olodaterol, tiotropium/olodaterol in Chinese patients provided significant improvement in lung function and quality of life, and the safety profiles were similar.

Abstract
Objective: To evaluate the efficacy and prognostic factors in core binding factor (CBF) acute myeloid leukemia (AML) under current therapy modalities, therefore optimizing the treatment strategies. Methods: Standard cytological and immune methods including next generation sequencing (NGS) were used for risk stratification. Complete remission (CR) rate, disease-free survival (DFS) and overall survival (OS) were assessed by multivariate Logistic and Cox regression models in a total of 206 adults (aged 16-65 years) with CBF-AML, including 152 AML patients with t(8;21) and 54 with inv(16). Results: The CR rate of inv(16) patients after first course was 54/54(100%), significantly higher than that of t(8;21) patients [127/147(86.4%), P=0.005]. The fusion transcript level and KIT mutation were independent factors related to CR rate in t(8;21) patients (P=0.044 and 0.027; respectively). DFS and OS in inv(16) patients tended to be more superior than that in t(8;21) patients (P=0.066 for DFS; P=0.306 for OS; respectively). Multivariate Cox identified negative expression of CD(19) and female gender the independent predictors of inferior DFS in t(8;21) patients (P=0.000 for CD(19); P=0.006 for sex; respectively). Analysis of combining CD(19) with gender indicated that females/CD(1)(9-)subpopulation had significantly poor DFS than did males/CD(19)(+) ones (Bonferroni-P<0.000 01). The number of mutations in each patient, FLT3-ITD and additional karyotype abnormalities did not affect CR rate and DFS (all P>0.05). Conclusions: Patients with inv(16) have better induction response than those with t(8;21). High level of fusion transcripts and positive KIT mutation are associated with low CR rate in t(8;21) patients. Negative CD(19) expression and female gender are independent predictors of inferior DFS in t(8;21) patients.

Abstract
The glucose transporter 4 (GLUT4) translocation is a vital link of insulin-induced glucose uptake in adipose tissue and skeletal muscle. It is an important topic in anti-diabetic research to explore novel agents to facilitate the role of insulin. The aim of this study was to verify the hypothesis that neuropeptide galanin may enhance insulin-induced GLUT4 translocation to increase glucose uptake in adipose tissue of type 2 diabetic models. Insulin and/or galanin were injected respectively or cooperatively into type 2 diabetic rats once a day for fifteen days. The results showed that administration of galanin significantly enhanced insulin-induced GLUT4 and vesicle-associated membrane protein 2 (VAMP2) translocation, Akt phosphorylation and glucose uptake, but not GLUT4 mRNA and protein expression levels in adipose cells. The beneficial roles of galanin on insulin-induced events may be blocked by MK-2206, an Akt inhibitor, indicating that the Akt phosphorylation is essential for promoting impact of galanin on the insulin-induced events. These results suggest that galanin may benefit insulin-induced GLUT4 and VAMP2 translocation, and subsequent glucose uptake via the activated Akt-VAMP2-GLUT4 pathway in adipose cells. These findings deepen our understanding of the anti-diabetic effect of galanin and its mechanism.

Abstract
PURPOSE In view of the principal role of Toll-like receptor 4 (TLR4) in mediating sterile inflammatory response contributing to osteoarthritis (OA) pathogenesis, we used lipopolysaccharide (LPS), a known TLR4 activator, to clarify whether modulation of TLR4 contributed to the protective actions of intra-articular administration of curcumin in a classical rat OA model surgically induced by anterior cruciate ligament transection (ACLT). METHODS The rats underwent ACLT and received 50μl of curcumin at the concentration of 1 mg mL-1 and 10 μg LPS by intra-articular injection once a week for 8 weeks. Morphological changes of the cartilage and synovial tissues were observed. Apoptotic chondrocytes were detected using TUNEL assay. The concentrations of IL-1β and TNF-ɑ in synovial fluid were determined using ELISA kits. The mRNA and protein expression levels of TLR4 and NF-κB p65 were detected by real-time PCR and Western blotting, respectively. RESULTS Intra-articular administration of curcumin significantly improved articular cartilage injury, suppressed synovial inflammation and down-regulated the overexpression of TLR4 and its downstream NF-κB caused by LPS-induced TLR4 activation in rat osteoarthritic knees. CONCLUSION The data suggested that the inhibition of TLR4 signal might be an important mechanism underlying a protective effect of local curcumin administration on OA.

Abstract
ABSTRACT Aims to investigate the effects of grape seed proanthocyanidin extract (GSPE) on production performance, metabolism, and anti-oxidative status of Holstein dairy cattle in early lactation. Forty-eight multiparous Holstein dairy cattle were assigned to four groups (CON, G20, G40 and G80) and supplied with 0, 20, 40, and 80mg GSPE/kg of body weight/day. G20 significantly increased milk yield compared with other groups. Milk protein and non-fat-solids were increased in G20, G40 and G80 groups compared with the control group only at the 7th day during the experiment. No significant difference was observed in milk fat and somatic cell count, nor on parameters of energy metabolism in blood, liver function and kidney function between the four groups. There was no significant difference in glutathione peroxidase, superoxide dismutase, total antioxidant capacity, and hydrogen peroxide between the groups; but the malondialdehyde content of G20 significantly increased at day 14 in comparison with CON, and tended to increase at the 28th day. In conclusion, feeding 20mg GSPE/kg of body weight/day was associated with a significant increase in milk yield without detrimental effects on liver or kidney function and with substantial energy metabolism and antioxidant parameters improvement in early lactation dairy cattle.

Abstract
OBJECTIVE To evaluate the development of blood transfusion services in Mainland China within the context of health-care system reform. BACKGROUND China launched a health-care reform program in 2009 to redistribute health-care resources, which are currently over-concentrated in well-developed cities. A geographically equitable blood transfusion service is key to achieving this goal. METHODS Based on the national survey of blood establishments in July 2015, total blood collection, whole-blood donations per 1000 population and the supply and demand relationship were analysed at the administrative region level. Areas at different developmental levels were compared in terms of total blood collection and human resources. RESULTS In 2014, Mainland China's 31 provinces showed wide variation, with total blood collection in blood facilities ranging from about 1000 units to over 600 000 units (each 200 mL), and the whole-blood donation rate per 1000 population, ranging from 1·48 to 17·09. 69% of the country's total collection, was concentrated in 29 provincial capitals, and 31% was in 311 non-capital cities. Of 97 personnel with doctorates, 74 worked in 32 provincial blood establishments, whereas the remaining 23 worked at the other 318 blood stations. In most provinces, per permanent resident donation was within 2-4 mL, and blood volume per inpatient was 10-35 mL regardless of the development of the transfusion service. CONCLUSION In 2014, China had an imbalanced development and insufficient access to blood transfusion services. This service must be redeployed at the national level to facilitate health-care reform in China.

Abstract
Pulmonary hypertension occurs in systemic lupus erythematosus (SLE) for several reasons, such as vasculopathy. Previous studies have indicated that the excessive activation of the complement alternative pathway might be involved in the pathogenesis of lupus nephritis, especially in the absence of factor H or its functional impairment. However, the clinical and pathological significance of the alternative complement activation in lupus nephritis patients with pulmonary hypertension remains elusive. The data on patients with pulmonary hypertension and non-pulmonary hypertension lupus nephritis were retrospectively analyzed in our centre. Major plasma levels of complement components were evaluated. The depositions of Bb, C3d and C5b-9 in the lung specimens of pulmonary hypertension combined with SLE patients were detected by immunofluorescence staining. Among 352 lupus nephritis cases, 24 were diagnosed with pulmonary hypertension and 328 with non-pulmonary hypertension. Higher levels of Bb and lower levels of factor H were detected in the pulmonary hypertension group in comparison with the negative group (P = 0.049, P = 0.024, respectively). Pulmonary hypertension was a risk factor for renal outcome as deduced by the log-rank and Cox test for survival analysis. C3d, C5b-9 and Bb were found to be positive in lung specimens of lupus nephritis patients with pulmonary hypertension. We concluded that activation of the complement alternative pathway may be involved in the pathogenesis of pulmonary hypertension in lupus nephritis.

Abstract
Brain-computer interfaces (BCIs) utilizing signals acquired with intracortical implants have achieved successful high-dimensional robotic device control useful for completing daily tasks. However, the substantial amount of medical and surgical expertise required to correctly implant and operate these systems significantly limits their use beyond a few clinical cases. A noninvasive counterpart requiring less intervention that can provide high-quality control would profoundly impact the integration of BCIs into the clinical and home setting. Here, we present and validate a noninvasive framework utilizing electroencephalography (EEG) to achieve the neural control of a robotic device for continuous random target tracking. This framework addresses and improves upon both the "brain" and "computer" components by respectively increasing user engagement through a continuous pursuit task and associated training paradigm, and the spatial resolution of noninvasive neural data through EEG source imaging. In all, our unique framework enhanced BCI learning by nearly 60% for traditional center-out tasks and by over 500% in the more realistic continuous pursuit task. We further demonstrated an additional enhancement in BCI control of almost 10% by using online noninvasive neuroimaging. Finally, this framework was deployed in a physical task, demonstrating a near seamless transition from the control of an unconstrained virtual cursor to the real-time control of a robotic arm. Such combined advances in the quality of neural decoding and the practical utility of noninvasive robotic arm control will have major implications on the eventual development and implementation of neurorobotics by means of noninvasive BCI.

Abstract
The objective of this experiment was to study the effects of dietary zinc (Zn) source on gene expression of Zn transporters (metallothionein [MT], ZIP 3, 5, 8, 9, 10, 11, 13, and 14, and ZnT 1, 4, 5, 6, 7, 9, and 10) in the jejunum and cecal tonsils of broilers challenged with coccidia or coccidia plus Clostridium perfringens. A 2 × 2 factorial design was used with 2 Zn sources (90 mg Zn/kg from either ZnSO4 or an organic Zn, Bioplex® Zn) and challenged with approximately 5,000 oocysts of Eimeria maxima at 14 d of age with or without C. perfringens (108 CFU/bird) at 18, 19, and 20 d of age (8 pens per treatment and 8 birds per pen) after which 1 bird/pen was sampled at 21 d of age. In the jejunum, co-infection resulted in higher ZnT 5 and 6 gene expression, while organic Zn fed birds had lower ZIP 5 and 11, and higher ZnT1. Additionally, an interaction of challenge by Zn source was noted wherein ZnT10 was unaffected by the C. perfringens in the organic Zn treatment but was 2.7-fold lower in the co-infected ZnSO4 fed birds. S100A9 gene expression, a biomarker of inflammatory response in necrotic enteritis, increased 2 and 2.8-fold in the cecal tonsils and jejunum with the co-infection, respectively. Supplementation with organic Zn lowered S100A9 by 1.9 and 4.4-fold in the cecal tonsils and jejunum, respectively, when birds were supplemented with ZnSO4. Notably, MT, ZIP 3, 8, 9, 10, 13, or 14, and ZnT 4, 7, and 9 were unaffected by Zn source and/or method of challenge. An interaction of challenge by Zn source was also noted for serum Zn concentration, which was reduced when birds were challenged with C. perfringens and fed ZnSO4 but no difference between challenge method when birds were fed organic Zn. Based on the expression of ZnT and ZIP genes, more Zn trafficking due to treatment occured in the jejunum than cecal tonsils, but further studies are needed to ascertain how Zn source regulates intracellular free Zn concentrations and whole-body Zn status during an enteric challenge.

The impact of chronic environmental metal and benzene exposure on human urinary metabolome among Chinese children and the elderly population. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2019; 169:232-239. [PMID: 30448706 DOI: 10.1016/j.ecoenv.2018.11.016] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 11/01/2018] [Accepted: 11/05/2018] [Indexed: 06/09/2023]
Abstract
The health effects of metals and benzene exposure have been extensively investigated; however, information on the impact of chronic environmental metal and benzene exposure on human urinary metabolome is limited. In this study, a total of 566 participants, including 352 elderly and 214 children, were split into the "exposed" and "control" groups. The urine samples of all the participants were collected and stored at - 80 °C until analysis. The urinary levels of 17 metals and S-phenylmercapturic acid (S-PMA) were determined by the ICP-MS and LC-MS/MS methods to comprehensively assess the personal metal and benzene exposure levels, respectively. Then, the individual levels of metal and benzene exposure were correlated to the metabolic consequences of ambient pollutant exposure, which were previously observed in our metabolomics study. As a result, multiple metals, including Cd, Co, Cr, Cu, Fe, Hg, Li, Mo, Ni, Pb, Se, and Zn, exhibited a significant linear dose-dependent association with one or more urinary metabolites, including two amino acids (pyroglutamic acid and 3-methylhistidine), three organic acids (azelaic acid, decenedioic acid, and hydroxytetradecanedioic acid), ten medium-chainacylcarnitines (heptenedioylcarnitine, octenedioylcarnitine, nonenedioylcarnitine, decenedioylglucuronide, 3-hydroxydecanoylcarnitine, dodecanedioylcarnitine, nonanoylcarnitine, decadienylcarnitine, hydroxydodecenoylcarnitine, dodecadienylcarnitine, and dodecenoylcarnitine), and one glucuronide conjugate (decenedioylglucuronide). These observations indicate that the increased environmental metal exposure has caused various oxidative stress-related effects, including the depletion of antioxidants, accelerated muscle proteolysis, elevated activity of UGTs, increased lipid peroxidation, and the disorder of mitochondrial lipid metabolism among exposed children and the elderly. The current study provides new insights into the biological effects induced by metal exposure in the environment.

Abstract
Objective: To analyze the clinical features, diagnosis and differential diagnosis of diffuse pulmonary meningotheliomatosis (DPM), a rare subtype of minute pulmonary meningothelial-like nodules (MPMN), so as to improve the understanding of this disorder. Methods: The clinical data of a patient diagnosed as DPM admitted in department of Respiratory Medicine, Peking University Third Hospital in August 2016 were reported and the related literatures were reviewed. With "pulmonary meningothelial-like nodules" , "minute pulmonary meningothelial-like nodules" or "diffuse pulmonary meningotheliomatosis" as the search terms, and the search time before November 1st 2017 for Wanfangdata, China National Knowledge Infrastructure (CNKI), and PubMed.Twenty-five articles were retrieved, among which 6 English (all case reports) articles were found with the search term "diffuse pulmonary meningotheliomatosis" involving 10 cases, and the other 19 articles (1 Chinese, 18 English) about MPMN mainly discussed non-DPM cases,including 13 case reports and 6 pathological/genetic studies. Results: A 68-year old female was admitted to the hospital because of intermittent cough and expectoration for more than 3 years and aggravation for 3 weeks. Her pulmonary CT showed diffuse minute nodules distributed randomly throughout both lungs, and did not improve after treatment with oral Moxifloxacin for 2 weeks. A video-assisted thoracoscopic biopsy was performed. The specimens showed MPMN and no other lesions, which confirmed the final diagnosis of DPM. She was followed without any medication therapy and her pulmonary CT showed stabilization of the lesions one year later. DPM was considered as a rare type of MPMN. A total of 11 cases were analyzed, including 10 cases reported in the literature. The patients included 1man and 10 women, aged 51 to 75 years, with an average age of (64±8) years. Among the 11 patients, 8 denied a history of smoking or of occupational exposure, 7 presented with dyspnea, shortness of breath, or fatigue, and 8 had mild abnormalities of pulmonary function test. The pulmonary CT of all the patients showed randomly distributed, diffuse bilateral small solid or ground-glass nodules, with the diameters less than 5 millimeters, some of which were cavitated. Only 1 patient had pulmonary thromboembolism, while the other 10 did not have any other lung diseases. All the patients were histologically diagnosed, 8 by open lung biopsies, 2 by transbronchial lung biopsy, and 1 by CT-guided fine needle aspiration. Three patients were followed for 12-92 months and the lung lesions were all stable. Conclusions: As a rare subtype of MPMN, DPM lacks specificity of clinical manifestations, and presents with diffuse bilateral small solid or ground-glass nodules, distributed randomly throughout both lungs. An early correct diagnosis depends on biopsy.

Abstract
Objective: To investigate the clinicopathologic characteristics, diagnostic features and prognosis of primary renal neuroendocrine carcinoma (NEC). Methods: The clinicopathologic data of eight cases of renal NEC was collected from January 2008 to December 2017 from Affiliated Hospital of Qingdao University. Immunohistochemical staining was performed, and follow-up information was analyzed, and the relevant literature reviewed. Results: The patients' mean age at diagnosis was 45 years (range, 27-66 years); five were women, and three were men. The tumors located on the left side in five patients, and on the right side in three. Five cases were detected incidentally, and three patients presented with loin pain. Microscopically, these cases included five well-differentiated NECs (three carcinoids, two atypical carcinoids), two small cell NECs, and one large cell NEC according to the World Health Organization classification of 2016. The tumors infiltrated the renal capsule in six cases. Necrosis was found in five cases. Vascular invasion with tumor emboli was seen in three cases. Lymph node metastasis was identified in one case. Immunohistochemically, the expression rates of neuroendocrine markers CD56, chromogranin A (CgA) and synaptophysin (Syn) were 6/8, 4/8, and 8/8 respectively. Some of the NECs were positive for epithelial markers CKpan (6/8, with three cases showing focal positivity) and CAM5.2 (4/8) of variable degrees. The Ki-67 proliferation index was≤3% in the carcinoids; ≥50% in the small cell carcinoma and large cell carcinoma; and 5% and 8% for the two cases of atypical carcinoid, respectively. All cases were negative for EMA, CK7, CA9, CD10, CD117, PAX2, PAX8, WT1, p63, S-100 and TTF1. Three patients (two with small cell carcinoma and one with large cell carcinoma) died of extensive metastases at 3 months, 4 months and 9 months after operation, while five patients were well, without recurrence or distant metastasis for follow-up period of one to nine years. Conclusions: Primary renal NEC is rare. Carcinoid is the most common histological type. The pathomorphological features and neuroendocrine markers (CD56, CgA, Syn), epithelial markers (CKpan, CAM5.2) and nephrogenic markers (PAX2, PAX8) are important for the diagnosis. Renal carcinoid tumors are indolent and prone to early metastasis, but are associated with prolonged survival. The small cell renal cell carcinoma and large cell carcinoma are highly malignant renal tumors with poor prognosis and short survival.

Abstract
OBJECTIVE To systematically assess the prevalence of frailty, including prefrailty, stratified prevalence according to frailty criteria, gender, age, and region, and the risk factors for frailty in China. DESIGN We conducted a systematic literature review and meta-analysis using articles available in 8 databases including PubMed, Cochrane Library, Web of Science, CINAHL Plus, China Knowledge Resource Integrated Database (CNKI), Wanfang Database, Chinese Biomedical Database (CBM), and Weipu Database (VIP). SETTING Cross-sectional and cohort data from Chinese community. PARTICIPANTS Community-dwelling adults aged 65 and older. MEASUREMENTS Two authors independently extracted data based upon predefined criteria. Where data were available we conducted a meta-analysis of frailty parameters using a random-effects model. RESULTS We screened 915 different articles, and 14 studies (81258 participants) were ultimately included in this analysis. The prevalence of frailty and prefrailty in individual studies varied from 5.9% to 17.4% and from 26.8% to 62.8%, respectively. The pooled prevalence of frailty and prefrailty were 10% (95% CI: 8% to 12%, I2 = 97.4%, P = 0.000) and 43% (95% CI: 37% to 50%, I2 = 98.0%, P = 0.000), respectively. The pooled frailty prevalence was 8% for the Fried frailty phenotype, 12% for the frail index, and 15% for the FRAIL scale. Age-stratified meta-analyses showed the pooled prevalence of frailty to be 6%, 15%, and 25% for those aged 65-74, 75-84, and ≥85 years old, respectively. The pooled prevalence of frailty was 8% for males and 11% for females. The pooled prevalence of frailty in Mainland China, Taiwan, and Hong Kong was 12%, 8%, and 14%, respectively. The pooled frailty prevalence was 10% in urban areas and 7% in rural areas. After controlling for confounding variables, increasing age (OR = 1.28, 95% CI: 1.2 to 1.36, I2 = 98.0%, P = 0.000), being female (OR = 1.29, 95% CI: 1.16 to 1.43, I2 =92.7%, P=0.000), activities of daily living (ADL) disability (OR = 1.72, 95% CI: 1.57 to 1.90, I2 = 99.7%, P = 0.000), and having three or more chronic diseases (OR = 1.97, 95% CI: 1.78 to 2.18, I2 = 97.5%, P = 0.000) were associated with frailty. CONCLUSIONS These findings of this review indicate an overall pooled prevalence of frailty among Chinese community-dwelling older people of 10%. Increasing age, being female, ADL disability, and having three or more chronic diseases were all risk factors for frailty. Further research will be needed to identify additional frailty risk factors in order to better treat and prevent frailty in the community.

Abstract
OBJECTIVE To investigate the etiological and clinical characteristics of immunocompetent patients with candidemia. METHODS The clinical and microbiological data of patients diagnosed as candidemia admitted in Peking University Third Hospital from January 2010 to June 2016 were retrospectively analyzed. Underlying diseases, Candida spp. colonization, clinical manifestations, microbiological data, treatment and the outcome were compared between the HIV-negative immunocompromised (IC) and nonimmunocompromised (NIC) patients. RESULTS A total of 62 cases diagnosed as candidemia were analyzed including 36 men and 26 women, with 16 to 100 years of age [(66.02±17.65) years]. There were 30 NIC and 32 HIV-negative IC patients respectively. In the NIC patients, there were 19 cases (19/30, 63.33%) with admission in intensive care unit (ICU), 21 (21/30, 70.00%) associated diabetes mellitus or uncontrolled hyperglycemia and 22 (22/30,73.33%) receiving invasive mechanical ventilation, while in the HIV-negative IC patients, there were 8 (8/32, 25.00%), 13 (13/32, 40.63%) and 7 (7/32, 21.88%) respectively (P<0.05). The NIC patients had higher acute physiology and chronic health evaluation (APACHE II) scores and sequential organ failure assessment (SOFA) scores both at admission (19.98±5.81, 6.04±6.14) and candidemia onset (25.61±6.52, 12.75±8.42) than the HIV-negative IC patients (APACHEII 15.09±5.82, 22.15±5.98) and SOFA 2.87±2.73, 7.66±5.64 respectively (P<0.05). In the NIC patients, twenty-one cases (21/30, 70.00%) died in hospital, while 14 cases (14/32, 43.75%) in HIV-negative IC. The crude mortality was significantly different between the two groups (P<0.05). By blood culture, Canidia albicans remained the the most prevalent isolates in all the patients. Clinical manifestation, Candida spp. colonization, etiology and drug susceptibility were also similar between NIC and HIV-negative IC patients (P>0.05). CONCLUSION Candidemia in NIC patients tends to occur in those who are much more critically ill, more often admitted in ICU, and more frequently have diabetes mellitus or uncontrolled hyperglycemia and receive invasive mechanical ventilation than HIV-negative IC patients. NIC patients also have poorer prognosis than HIV-negative IC patients. Clinical manifestations, and microbiological characteristics are similar between HIV-negative IC and NIC patients.

Abstract
Basic-helix-loop-helix (bHLH) transcription factors play an important role in various organs' development; however, a tooth-specific bHLH factor has not been reported. In this study, we identified a novel tooth-specific bHLH transcription factor, which we named AmeloD, by screening a tooth germ complementary DNA (cDNA) library using a yeast 2-hybrid system. AmeloD was mapped onto the mouse chromosome 1q32. Phylogenetic analysis showed that AmeloD belongs to the achaete-scute complex-like ( ASCL) gene family and is a homologue of ASCL5. AmeloD was uniquely expressed in the inner enamel epithelium (IEE), but its expression was suppressed after IEE cell differentiation into ameloblasts. Furthermore, AmeloD expression showed an inverse expression pattern with the epithelial cell-specific cell-cell adhesion molecule E-cadherin in the dental epithelium. Overexpression of AmeloD in dental epithelial cell line CLDE cells resulted in E-cadherin suppression. We found that AmeloD bound to E-box cis-regulatory elements in the proximal promoter region of the E-cadherin gene. These results reveal that AmeloD functions as a suppressor of E-cadherin transcription in IEE cells. Our study demonstrated that AmeloD is a novel tooth-specific bHLH transcription factor that may regulate tooth development through the suppression of E-cadherin in IEE cells.

Abstract
OBJECTIVE To investigate the distribution of airway inflammation phenotype in patients with bronchial asthma (asthma), and to analyze clinical characteristics, inflammatory cytokines, pulmonary small vessels remodeling and small airway wall remodeling in patients with neutrophilic asthma. METHODS Sixty-three patients with asthma were enrolled from January 2015 to December 2015 in Peking University Third Hospital. Clinical data including gender, age, body mass index (BMI), pulmonary function tests (PFTs), asthma control test (ACT) were recorded. All the patients underwent sputum induction. The cellular composition of the sputum was evaluatedand the concentration of active MMP-9 in the sputum tested. Blood routine tests were done and the concentration of IgE, periostin, and TGF-beta1 levels were measured in serum by enzyme-linked immunosorbent assay (ELISA). Small airway wall remodeling was measured in computed tomography (CT) scans, as the luminal diameter, luminal area, wall thickness and wall area % adjusted by body surface area (BSA) at the end of the 6th generation airway, in which the inner diameter was less than 2 mm. Small vascular alterations were measured by cross-sectional area (CSA), and the total vessel CSA < 5 mm2 was calculated using imaging software. RESULTS The distributions of airway inflammatory phenotypes of the asthmatic patients were as follows: neutrophilic asthma (34.9%, 22/63), eosinophilic asthma (34.9%, 22/63), mixed granulocytic asthma (23.8%, 15/63), and paucigranulocytic asthma (6.3%, 4/63). The neutrophilic subtype patients had a significantly higher active MMP-9 level in sputum compared with the eosinophilic phenotypepatuents, as 179.1 (74.3, 395.5) vs. 50.5 (9.7, 225.8), P<0.05. Sputum neutrophil count was negatively correlated with FEV1%pred (r=-0.304,P<0.05), and positively correlated with active MMP-9 level in sputum (r=-0.304, P<0.05), and positive correlation trend with airway wall thickness (r=0.533, P=0.06). There was a significantly negative correlation of active MMP-9 level in sputum with FEV1%pred (r=-0.281, P<0.05), in positive correlation with small airway wall area (%)(r=0.612, P<0.05), and inpositive correlation trend with airway wall thickness (r=0.612, P=0.06). Neutrophils count in peripheral blood was positively correlated with neutrophil counts in sputum. CONCLUSION Neutrophil count in airway is related to lung function in asthmatic patients. Neutrophils may accelerate small airway wall remodeling through the release of active MMP-9. Neutrophil count in peripheral blood is related to neutrophils count in sputum, which may be used as a substitute for evaluating inflammatory phenotype.

Abstract
Now, the occurrence of pharmaceuticals in natural environment has been frequently reported around the world. As a kind of biologically active compounds specially designed to be effective even at very low concentration levels, pharmaceuticals in the environment could have adverse impacts to the health of human beings or other non-targeted organisms due to long-term exposures. To minimize the pharmaceutical pollution from the perspective of drug administration, a new concept called as eco-pharmacovigilance (EPV) has been proposed as a kind of pharmacovigilance(PV) for the environment. However, as a new and comprehensive science, EPV has not sophisticated methods in practice and formalized implementation model up to now. Since EPV is a special kind of PV, it could be feasible to draw on the experience of PV as a possible and reasonable starting point for EPV. In this paper, we discussed the common methods and activities used in PV including spontaneous reporting, intensive monitoring, database studies, and their potential applicability to the environment. And we concluded that these common methods in PV could be adapted and applied to EPV. But there is still the need for organizational, technical and financial supports of the EPV system.

Abstract
OBJECTIVES Pentraxin 3 (PTX3) contributes to resistance to Aspergillus infections. This study aimed to evaluate the presence of PTX3 in bronchoalveolar lavage fluid (BALF) and plasma in non-neutropenic patients with pulmonary aspergillosis. METHODS BALF (n = 211) and plasma samples (n = 307) were collected from patients initially suspected of having pulmonary aspergillosis. Among these, 112 cases (51 BALF samples and 89 plasma samples) were proven to be pulmonary aspergillosis. These cases were classified as invasive pulmonary aspergillosis (IPA), subacute invasive aspergillosis (SAIA) and chronic pulmonary aspergillosis (CPA). The remaining cases were non-aspergillosis controls and were diagnosed with community-acquired pneumonia (CAP), lung cancer and pulmonary cryptococcosis. Plasma samples from healthy controls (n = 30) were also collected. RESULTS The median (interquartile range, IQR) BALF PTX3 for aspergillosis cases was significantly higher than for non-aspergillosis cases: 6.97 (2.91-13.51) ng/mL versus 1.26 (0.76-1.76) ng/mL. When the PTX3 threshold was set at 1.9 ng/mL, sensitivity and specificity of BALF PTX3 for aspergillosis were 86.3% (95%CI 83.8-88.4%) and 82.5% (95%CI 79.7-85.0%), respectively. The median (IQR) plasma PTX3 for aspergillosis cases was significantly higher than for non-aspergillosis cases and healthy controls: 7.10 (3.36-9.53) ng/mL versus 1.57 (0.86-2.35) ng/mL versus 1.10 (0.49-1.51) ng/mL. With a PTX3 threshold of 2.3 ng/mL, sensitivity and specificity were 79.8% (95%CI 70.1-81.2%) and 72.1% (95%CI 69.5-74.5%) respectively. CONCLUSIONS BALF and plasma PTX3 may be biomarkers for differentiating aspergillosis from other conditions such as CAP, lung cancer, and pulmonary cryptococcosis in non-neutropenic patients.

Abstract
Sheep production systems in northwest China depend mostly on natural grasslands. Seasonal growth and maturity fluctuations can cause periodical restrictions in food quality and quantity. These fluctuations, in turn, result in variability in fat deposition and fatty acid profiles in different fat depots. Consequently, the study objective was to compare fat deposition, intramuscular fat (IMF) percentage and fatty acid profiles of the longissimus dorsi (LD), kidney fat (KF), tail fat (TF), and subcutaneous fat (SF) in lambs under ME restrictions similar to seasonal changes observed in the natural grasslands of northwest China. Nineteen male Dorper × Small Tailed Han lambs were assigned to 2 treatments, a control (CON) fed at 1.0 MJ / W × d and restricted (RES) by restricting ME sequentially every 30 d (0.56 MJ / W × d, 0.84 / W × d, 1.0 MJ / W × d, 0.84 MJ / W × d, 0.56 MJ / W × d, 0.28 MJ / W × d). All lambs were harvested at the end of the 180 d experimental period. Compared to CON fed lambs, restricting ME resulted in lesser IMF, fat deposition indexes ( < 0.05) except testicular and heart fat and greater ( < 0.05) SFA in LD, KF, and TF depots. The RES fed lambs had greater ( < 0.05) -3 PUFA, eicosatrienoic acid (C20:3n3), eicosapentaenoic acid (C20:5n3, EPA), and trans-linolelaidic acid (C18:2n6t) in LD muscle. The conjugated linoleic acids (CLA) content was greater in the SF depots of the CON fed lambs compared to the RES fed lambs. Fatty acid ratios (unsaturated fatty acid; USFA:SFA, MUFA:SFA, PUFA:SFA), and percentage USFA in RES fed lambs were lesser in muscle and adipose tissue compared to CON fed lambs ( < 0.05), except SF depots. In RES fed lambs, EFA were less ( < 0.05) in LD and KF depots and the ratios of functional fatty acids were lesser in LD and some adipose tissues ( < 0.05), including lesser n-6:n-3 in KF and SF ( < 0.05) depots, lesser USFA, SFA, MUFA, SFA in LD, KF, and TF ( < 0.05) depots, and lesser PUFA and SFA in LD and TF ( < 0.05) depots. Results from this research demonstrate that sequential energy restriction, as might be experience during seasonal forage quality and quantity changes in natural grasslands, result in lesser intramuscular fat with associated lesser quality, as well as, changes in fatty acid composition in different fat depots, which has implications for both meat quality and animal physiological functions.

Abstract
Objective: To analysis the correlative factors that probably affect serum leptin levels in asthmatic patients. Methods: Seventy-eight patients with asthma and 29 health controls who were admitted into outpatient clinic of Peking University Third Hospital from April 2014 to December 2015 were consecutively enrolled in our study prospectively. Serum leptin level was measured by enzyme-linked immunosorbent assay (ELISA). The sex, body mass index (BMI), onset age of asthma, allergen detection test, induced sputum cell count and classification, lung function test and asthma control level were recorded. Asthmatic patients were further divided into groups according to these factors and serum leptin levels were compared among groups. Results: Serum leptin levels were not different between asthmatic patients and health controls [(15.0±10.4) vs (15.2±11.7) μg/L, P=0.939]. Female asthmatic patients had significantly higher serum leptin levels than male [(18.2±10.7) vs (7.9±4.8) μg/L, P<0.001]. Asthmatic patients with obesity had significantly higher serum leptin levels than asthmatic patients with overweight, with normal BMI, with underweight and health controls [(29.7±10.8) vs (17.1±11.1), (11.8±7.7), (9.1±0.96), (15.2±11.7) μg/L, all P<0.01]. Serum leptin level was positively related to percentage of induced sputum eosinophil in female asthmatic patients (r=0.331, P=0.032). Onset age of asthma, positive allergen detection, airflow limitation or asthma control level did not affect serum leptin level. Conclusion: Sex and BMI are important factors affecting serum leptin levels in patients with asthma.

Abstract
Abstract:A method is described to process and interpret multi-channel bioelectrical signals. The bioelectrical signals were recorded noninvasively over the body surface of human subjects at 120 sites. The body surface Laplacian maps were then constructed from the multi-channel bioelectrical potential measurement. The method was evaluated by means of computer simulations, and applied to imaging cardiac electrical activity. The present investigation suggests body surface Laplacian mapping provides an important means in interpreting bioelectrical signals.

Abstract
Abstract:The objective of this study is to evaluate the spatial resolution of body surface Laplacian maps (BSLMs) in localizing ventricular electrical activity by means of computer simulation. A 3-D computer heart-torso model was used to simulate cardiac electrical activity and the body surface maps. A two-site pacing protocol was used to generate two simultaneously activated myocardial events on the anterior epicardial wall and the anterior endocardial wall. Following the pacing, the BSLMs and the body surface potential maps (BSPMs) were calculated and compared with the known activation pattern. As a result, the BSLMs showed superior resolution than the BSPMs for localized initial ventricular activity. In summary, the present study suggests that body surface Laplacian mapping may provide a useful methodology for the clinical diagnosis of cardiac electrical abnormalities.

Abstract
Summary
Objectives:
The objective of this study was to explore suitable spatial filters for inverse estimation of cortical potentials from the scalp electroencephalogram. The effect of incorporating noise covariance into inverse procedures was examined by computer simulations and tested in human experiment.
Methods:
The parametric projection filter, which allows inverse estimation with the presence of information on the noise, was applied to an inhomogeneous three-concentric-sphere model under various noise conditions in order to estimate the cortical potentials from the scalp potentials. The method for determining the optimum regularization parameter, which can be applied for parametric inverse techniques, is also discussed.
Results:
Human visual evoked potential experiment was carried out to examine the performance of the proposed restoration method. The parametric projection filter gave more localized inverse solution of cortical potential distribution than the truncated SVD and Tikhonov regularization.
Conclusion:
The present simulation results suggest that incorporation of information on the noise covariance allows better estimation of cortical potentials, than inverse solutions without knowledge about the noise covariance, when the correlation between the signal and noise is low.

Abstract
Abstract:For the activation study of the brain, dipole localization from the scalp potential is one of the most promising techniques to realize a reasonable temporal resolution which cannot be realized in functional MR and PET. The goal of our study is to estimate inversely the electrical brain activity in the form of several dipoles from the scalp potential, using a network inversion technique. As a basic approach, we have inversely estimated several dipoles from the potential distribution on a spherical surface, in the homogeneous sphere model.In the training phase, by expanding the neural network input dimensions being redundant, the network can easily learn the forward mapping. In the inversion phase, the space of the expanded-network-input-vector can be narrowed by introducing a penalty term. Additionally, a consensus term was used to force several dipoles to have a similar orientation. We estimate that this is applicable to the localization of several dipoles that reflect the actual brain activity, especially in the visual evoked potentials.

Abstract
OBJECTIVE Combining repetitive transcranial magnetic stimulation (rTMS) with brain-computer interface (BCI) training can address motor impairment after stroke by down-regulating exaggerated inhibition from the contralesional hemisphere and encouraging ipsilesional activation. The objective was to evaluate the efficacy of combined rTMS + BCI, compared to sham rTMS + BCI, on motor recovery after stroke in subjects with lasting motor paresis. APPROACH Three stroke subjects approximately one year post-stroke participated in three weeks of combined rTMS (real or sham) and BCI, followed by three weeks of BCI alone. Behavioral and electrophysiological differences were evaluated at baseline, after three weeks, and after six weeks of treatment. MAIN RESULTS Motor improvements were observed in both real rTMS + BCI and sham groups, but only the former showed significant alterations in inter-hemispheric inhibition in the desired direction and increased relative ipsilesional cortical activation from fMRI. In addition, significant improvements in BCI performance over time and adequate control of the virtual reality BCI paradigm were observed only in the former group. SIGNIFICANCE When combined, the results highlight the feasibility and efficacy of combined rTMS + BCI for motor recovery, demonstrated by increased ipsilesional motor activity and improvements in behavioral function for the real rTMS + BCI condition in particular. Our findings also demonstrate the utility of BCI training alone, as shown by behavioral improvements for the sham rTMS + BCI condition. This study is the first to evaluate combined rTMS and BCI training for motor rehabilitation and provides a foundation for continued work to evaluate the potential of both rTMS and virtual reality BCI training for motor recovery after stroke.

Abstract
Summary
Objective
: The objective of this study is to explore suitable spatial filters for inverse estimation of cortical equivalent dipole layer imaging from the scalp electroencephalogram. We utilize cortical dipole source imaging to locate the possible generators of scalpmeasured movement-related potentials (MRPs) in human.
Methods
: The effects of incorporating signal and noise covariance into inverse procedures were examined by computer simulations and experimental study. The parametric projection filter (PPF) and parametric Weiner filter (PWF) were applied to an inhomogeneous threesphere head model under various noise conditions.
Results
: The present simulation results suggest that the PWF incorporating signal information provides better cortical dipole layer imaging results than the PPF and Tikhonov regularization under the condition of moderate and high correlation between signal and noise distributions. On the other hand, the PPF has better performance than other inverse filters under the condition of low correlation between signal and noise distributions. The proposed methods were applied to self-paced MRPs in order to identify the anatomic substrate locations of neural generators. The dipole layer distributions estimated by means of PPF are well-localized as compared with blurred scalp potential maps and dipole layer distribution estimated by Tikhonov regularization. The proposed methods demonstrated that the contralateral premotor cortex was preponderantly activated in relation to movement performance.
Conclusions
: In cortical dipole source imaging, the PWF has better performance especiallywhen the correlation between the signal and noise is high. The proposed inverse method was applicable to human experiments of MRPs if the signal and noise covariances were obtained.

Abstract
Objective: To investigate the clinical value of two-dimensional speckle tracking echocardiography(2D-STE) combined with high-sensitive cardiac troponin T (hs-cTnT) in early detection of the cardiotoxicity induced by chemotherapy drug. Methods: Seventy-five non-Hodgkin's lymphoma patients who received the CHOP regimen were recruited in this study. Conventional echocardiography and 2D-STE were performed on these patients before chemotherapy, the second day after the third course of chemotherapy (during chemotherapy) and the second day after the last course of chemotherapy (after chemotherapy). The parameters included left ventricular ejection fraction (LVEF), global longitudinal strain (LS), global circumferential strain (CS) and global radial strain (RS). The serum hs-cTNT levels were tested simultaneously. Results: Three cycles of CHOP were completed in 30 patients and 6-8 cycles of CHOP were completed in 45 patients. The LVEF of 75 patients before, during and after chemotherapy was (63.8±2.6)%, (63.8±2.8)% and (64.0±3.3)%, respectively, without significant difference (P=0.91). However, the LS of 75 patients before, during and after chemotherapy was (-18.5±1.7)%, (-16.5±1.9)% and (-16.0±1.6)%, respectively. The CS was (-20.9±2.9)%, (-19.3±3.5)% and (-19.2±3.2)%, respectively. The RS was (39.2±6.4)%, (35.3±5.2)% and (35.0±6.2)%, respectively. The hs-cTnT was (0.001 0±0.002 0)ng/ml, (0.006 3±0.008 9)ng/ml and (0.007 3±0.003 8)ng/ml, respectively. The LS, CS and RS were significantly decreased while hs-cTnT was significantly increased during chemotherapy when compared to those before chemotherapy (all of P<0.01). Alternatively, the LS, CS, RS and hs-cTnT after chemotherapy were marginally different from those during chemotherapy (all of P>0.05). Moreover, T(LS-SD), T(CS-SD) and T(RS-SD) showed no significant difference before, during and after chemotherapy (all of P>0.05). The reduction of LS was positively associated with the enhancement of hs-cTnT after chemotherapy (r=0.60, P<0.01). Conclusion: 2D-STE combined with hs-cTnT can effectively and precisely detect the occult cardiotoxicity induced by anthracycline.

Abstract
Environmental experts have made great efforts to control pharmaceutical pollution. However, the control of emerged environmental problems caused by medicines should draw more attention of pharmacy and pharmacovigilance researchers. Ecopharmacovigilance (EPV) as a kind of pharmacovigilance for the environment is recognized worldwide as crucial to minimize the environmental risk of pharmaceutical pollutants. But continuing to treat the pollution of pharmaceuticals as a group of substances instead of targeting individual pharmaceuticals on a prioritized basis will lead to a significant waste of resources. Considering vulture population decline caused by non-steroidal anti-inflammatory drugs (NSAIDs) residues, we presented a global-scale analysis of 139 reports of NSAIDs occurrence across 29 countries, in order to provide a specific context for implementing EPV. We found a heavy regional bias toward research in Europe, Asia and America. The top 5 most frequently studied NSAIDs included ibuprofen, diclofenac, naproxen, acetaminophen and ketoprofen. The profile of NSAIDs was dominated by acetaminophen in wastewater influents and effluents. Ibuprofen was the most abundant NSAID in surface water. Only 9 NSAIDs were reported in groundwater samples. And majority of NSAIDs were detected in solid matrices at below 1μg/g except for ketoprofen, diclofenac and ibuprofen. From a pharmacy perspective, we get some implication and propose some management practice options for EPV implementation. These include: Further popularizing and applying the concept of EPV, together with developing relevant regulatory guidance, is necessary; More attention should be paid to how to implement EPV for the pollution control of older established drugs; Triggering "a dynamic watch-list mechanism" in conjunction with "source control"; Implementing targeted sewage treatment technologies and strengthening multidisciplinary collaboration; Pharmaceutical levels in aquatic organisms as biological indicators for monitoring pharmaceutical pollution within the water environment; Upgrading drinking water treatment plants with the aim of removing pharmaceutical residues; Paying more attention to EPV for pharmaceuticals in solid matrices.

Abstract
Objective: To describe diseases that may present with the reversed halo sign (RHS) on high-resolution CT, and therefore to improve the recognition of this thoracic radiological feature. Methods: We retrospectively reviewed the HRCT scans and medical records of 5 patients who presented with RHS on chest CT from Peking University Third Hospital. With "reversed halo sign, fairy ring, atoll sign" as the Chinese and English keywords, 420 cases from the literatures were also reviewed through PubMed, Wanfang and CNKI databases until August 2015. Results: The 5 patients were all males, aging 19-55 years. The diagnosis of the diseases included cryptogenic organizing pneumonia (patient 1), pulmonary tuberculosis (patient 2), pulmonary infarction (patient 3), pulmonary edema (patient 4) and mycoplasma pneumonia (patient 5). Literature review showed that RHS was observed in 206 cases of infectious pulmonary diseases and 219 cases of noninfectious pulmonary diseases. Invasive fungal infection (including 59 cases of mucormycosis and 27 aspergillosis) and pulmonary tuberculosis (79 cases) predominated in infectious pulmonary diseases. However, in non-infectious pulmonary diseases, RHS was most frequently observed in organizing pneumonia (66%), sarcoidosis, lung cancer, pulmonary infarction, pulmonary edema and other interstitial lung diseases. There were some differences in the morphologic findings of RHS among invasive fungal infection, pulmonary tuberculosis and organizing pneumonia. In addition, our patient with mycoplasma pneumonia was the first case reported to present with RHS on HRCT. Conclusions: Although a wide spectrum of pulmonary diseases may present with RHS on chest CT, this sign is still a characteristic thoracic radiological feature, which is more commonly found in organizing pneumonia, pulmonary tuberculosis and invasive fungal infection, and is helpful in differential diagnosis.
