Abstract
Background The use of cerebral embolic protection devices during transcatheter aortic valve implantation (TAVI) reveals conflicting data. Aims This updated meta-analysis aims to evaluate the efficacy and safety of the SENTINEL Cerebral Protection System. Methods A literature search for relevant studies up to September 2022 was performed. Study outcomes were divided based on time period - overall (up to 30 days) and short (≤7 days). The outcomes studied include stroke (disabling, non-disabling), mortality, neuroimaging findings, transient ischaemic attack, acute kidney injury and major vascular and bleeding complications. Results A total of 15 studies involving 294,134 patients were included. Regarding overall outcomes, significant reductions were noted for mortality (odds ratio [OR] 0.60, 95% confidence interval [CI]: 0.41-0.88; p=0.008), all stroke (OR 0.64, 95% CI: 0.46-0.88; p=0.006) and disabling stroke (OR 0.42, 95% CI: 0.23-0.74; p=0.003) using the SENTINEL device. No significant differences were noted for other outcomes. There was significant heterogeneity across the studies for mortality (p=0.013) and all stroke (p=0.003). Including only randomised data (n=4), there was only significant reduction in the incidence of disabling stroke (OR 0.39, 95% CI: 0.17-0.89; p=0.026) in the SENTINEL group. In studies reporting ≤7-day outcomes (n=8), use of the SENTINEL device demonstrated significantly lower rates of all stroke (p<0.001), disabling stroke (p<0.001) and major bleeding complications (p=0.02). No differences in neuroimaging outcomes were noted. Conclusions In this updated meta-analysis, use of the SENTINEL Cerebral Protection System was associated with lower rates of mortality, all stroke and disabling stroke, although significant heterogeneity was noted for mortality and all stroke. Including exclusively randomised data, there was only significant reduction in the incidence of disabling stroke. No significant adverse outcomes with device use were noted.

Abstract
OBJECTIVES The aim of this study was to examine the disease burden of lung cancer attributable to particulate matter (PM2.5) pollution in China from 1990 to 2019. STUDY DESIGN Data from the Global Burden of Disease Study 2019 were used to estimate the disease burden of tracheal, bronchus and lung cancer attributed to PM2.5 over time in China. METHODS Joinpoint regression models were applied to disability-adjusted life years (DALYs) to assess the time trends and estimate the impact of PM2.5 on the overall disease burden of lung cancer. Furthermore, age-period-cohort models were conducted to assess the relationships between lung cancer DALYs attributed to PM2.5 exposure and age, calendar period and birth cohort trends in China from 1990 to 2019. RESULTS Lung cancer DALYs attributable to household air pollution from solid fuels decreased with an average annual percent change (AAPC) of 2.9 % per 100,000 population, while those attributable to ambient particular matter pollution (APE) increased (AAPC: -4.7 % per 100,000 population) over the past 30 years. The burden of lung cancer in terms of DALYs in males was higher than in females, and it demonstrated an age-dependent increase. The period and cohort effects also had significant impacts on the DALYs rates of lung cancer attributable to APE, indicating an overall increase in lung cancer DALYs for all age groups in each year. CONCLUSIONS This study highlights the need for effective strategies to reduce PM2.5 exposure in China, particularly from outdoor sources. Gender differences and age, period and cohort effects observed in the study provide valuable insights into long-term trends of lung cancer burden attributed to PM2.5.

Abstract
RATIONALE The clinical manifestations of Fabry disease affect the nerves, kidneys, heart, skin, gastrointestinal tract and eyes. Our aim is to familiarize people with the FD diagnostic process by reporting this case. PATIENT CONCERNS A 79-year-old-male patient presented with muscle pain and weakness in the extremities, also with an increasing erythrocyte sedimentation rate and C-reactive protein. Further examinations revealed that multiple organ involvement, such as rash, myocardial hypertrophy, peripheral neuropathy. DIAGNOSES Cardiac MR demonstrated hypertrophic cardiomyopathy, myocardial fibrosis and low myocardial T1 value. The patient was eventually diagnosed with Fabry disease through proteomics and genetic testing. INTERVENTIONS The treatment is enzyme replacement therapy (ERT). But this patient could not afford ERT and was given only general symptomatic treatment, pregabalin, and a gradual reduction in glucocorticoid. OUTCOMES The patient's symptoms of joint pain and muscle weakness reduced significantly, and ESR and CRP had decreased to normal. LESSONS FD is a rare disease and difficult to diagnose, but rare does not mean invisible. FD may present with signs and symptoms of rheumatic diseases. Rheumatologists should be aware and concerned about this disease.

Abstract
Affective information contained in words is gaining increased attention among neurolinguists and psycholinguists around the world. This study established the Affective Norms for Chinese Words (ANCW) with valence, arousal, dominance, and concreteness ratings for 4030 words that were Chinese adaptations of the CET-4 (The National College English Test Band 4) official syllabus. Despite the existing Chinese affective norms such as the Chinese Affective Words System (CAWS), the ANCW provides much more and richer Chinese vocabulary. By using 7-point (ranging from 1 to 7) Likert scales in a paper-and-pencil procedure, we obtained ratings for all variables from 3717 Chinese undergraduates. The ANCW norms possessed good response reliability and were compatible with prior normative studies in Chinese. The pairwise correlation analysis revealed quadratic relations between valence and arousal, arousal and dominance, as well as valence and concreteness. Additionally, valence and dominance, as well as arousal and concreteness, presented a linear correlation, and concreteness and dominance were correlated. The ANCW provides reliable and standardized stimulus materials for further research involving emotional language processing.

Abstract
The availability of direct oral anticoagulants (DOACs) with known lower bleeding risk compared with warfarin have raised questions about the role of left atrial appendage closure (LAAC). We aimed to perform a meta-analysis to compare the clinical outcomes for LAAC versus DOACs. All studies directly comparing LAAC with DOACs up to January 2023 were included. The outcomes studied included the combined major adverse cardiovascular (CV) events outcomes, ischemic stroke and thromboembolic events, major bleeding, CV mortality, and all-cause mortality. Hazard ratios (HRs) and their 95% confidence interval were extracted or estimated from the data and pooled together with a random-effects model. A total of 7 studies (1 randomized controlled trial, 6 propensity-matched observational studies) were finally included, with a pooled population of 4,383 patients who underwent LAAC and 4,554 patients on DOACs. There were no significant differences between patients who underwent LAAC and patients on DOACs in terms of baseline age (75.0 vs 74.7, p = 0.27), CHA2DS2-VASc score (5.1 vs 5.1, p = 0.33), or HAS-BLED score (3.3 vs 3.3, p = 0.36). After a mean weighted follow-up of 22.0 months, LAAC was associated with significantly lower rates of combined major adverse CV event outcomes (HR 0.73 [0.56 to 0.95], p = 0.02), all-cause mortality (HR 0.68 [0.54 to 0.86], p = 0.02), and CV mortality (HR 0.55 [0.41 to 0.72], p<0.01). There were no significant differences in the rates of ischemic stroke or systemic embolism (HR 1.12 [0.92 to 1.35], p = 0.25), major bleeding (HR 0.94 [0.67 to 1.32], p = 0.71), or hemorrhagic stroke (HR 1.07 [0.74 to 1.54], p = 0.74) between LAAC and DOAC. In conclusion, percutaneous LAAC was found to be as efficacious as DOACs for stroke prevention, with lower all-cause and CV mortality. The rates of major bleeding and hemorrhagic stroke were similar. LAAC has a potential role to play in stroke prevention in patients with atrial fibrillation in the era of DOACs, but further randomized data are needed.

Abstract
Deep eutectic solvents (DESs) are a mixture of hydrogen bond donor (HBD) and hydrogen bond acceptor (HBA) molecules that can consist, respectively, of natural plant metabolites such as sugars, carboxylic acids, amino acids, and ionic molecules, which are for the vast majority ammonium salts. Media such as DESs are modular tools of sustainability that can be pointed toward the extraction of bioactive molecules due to their excellent physicochemical properties, their relatively low price, and accessibility. The present review focuses on the application of DESs for protein extraction and purification. The in-depth effects and principles that apply to DES-mediated extraction using various renewable biomasses will be discussed as well. One of the most important observations being made is that DESs have a clear ability to maintain the biological and/or functional activity of the extracted proteins, as well as increase their stability compared to traditional solvents. They demonstrate true potential for a reproducible but more importantly, scalable protein extraction and purification compared to traditional methods while enabling waste valorization in some particular cases.

Abstract
Introduction Lupus nephritis (LN) is a major risk factor of morbidity and mortality. Glomerular injury is associated with different pathogeneses and clinical presentations in LN patients. However, the molecular mechanisms involved are not well understood. This study aimed to explore the molecular characteristics and mechanisms of this disease using bioinformatics analysis. Methods To characterize glomeruli in LN, microarray datasets GSE113342 and GSE32591 were downloaded from the Gene Expression Omnibus database and analyzed to determine the differentially expressed genes (DEGs) between LN glomeruli and normal glomeruli. Functional enrichment analyses and protein–protein interaction network analyses were then performed. Module analysis was performed using the Search Tool for the Retrieval of Interacting Genes/Proteins and Cytoscape software. Immunofluorescence staining was performed to identify the glomerular expression of S100A8 in various International Society of Nephrology/Renal Pathology Society (ISN/RPS) class LN patients. The image of each glomerulus was acquired using a digital imaging system, and the green fluorescence intensity was quantified using Image-Pro Plus software. Results A total of 13 DEGs, consisting of 12 downregulated genes and one upregulated gene (S100A8), were identified in the microarray datasets. The functions and pathways associated with the DEGs mainly include inflammatory response, innate immune response, neutrophil chemotaxis, leukocyte migration, cell adhesion, cell–cell signaling, and infection. We also found that monocytes and activated natural killer cells were upregulated in both GSE113342 and GSE32591. Glomerular S100A8 staining was significantly enhanced compared to that in the controls, especially in class IV. Conclusions The DEGs identified in the present study help us understand the underlying molecular mechanisms of LN. Our results show that glomerular S100A8 expression varies in different pathological types; however, further research is required to confirm the role of S100A8 in LN.

Abstract
Interictal epileptiform spikes (IES) of scalp electroencephalogram (EEG) signals have a strong relation with the epileptogenic region. Since IES are highly unlikely to be detected in scalp EEG signals, the primary diagnosis depends heavily on the visual evaluation of IES. However, visual inspection of EEG signals, the standard IES detection procedure is time-consuming, highly subjective, and error-prone. Furthermore, the highly complex, nonlinear, and nonstationary characteristics of EEG signals lead to the incomplete representation of EEG signals in existing computer-aided methods and consequently unsatisfactory detection performance. Therefore, a novel multiview feature fusion representation (MVFFR) method was developed and combined with a robustness classifier to detect EEG signals with/without IES. MVFFR comprises two steps: First, temporal, frequency, temporal-frequency, spatial, and nonlinear domain features are transformed by the IES to express the latent information effectively. Second, the unsupervised infinite feature-selection method determines the most distinct feature fusion representations. Experimental results using a balanced dataset of six patients showed that MVFFR achieved the optimal detection performance (accuracy: 89.27%, sensitivity: 89.01%, specificity: 89.54%, and precision: 89.82%) compared with other feature ranking methods, and the MVFFR-related method were complementary and indispensable. Additionally, in an independent test, MVFFR maintained excellent generalization capacity with a false detection rate per minute of 0.15 on the unbalanced dataset of one patient.

Abstract
Chinese materia medica decoction pieces (CMMDPs), one of the three pillars of the Chinese materia medica industry, are a key link in the Chinese materia medica industrial chain. Industrialization is the only way for the modernization of CMMDPs. This review mainly summarizes the characteristics, history, current situation and prospect of CMMDPs industry, providing a new reference for promoting the flourishing development of the industrialization of CMMDPs and for serving massive health industry. The literature was collected from databases including Web of Science, PubMed, Elsevier and CNKI (Chinese). CMMDPs industry has the characteristics of regionalism, resource dependency, customer diversity and low industrial concentration. Deeply processed products include traditional Chinese medicine (TCM) formula granules, small-packed decoction pieces, ultrafine decoction pieces, puffed decoction pieces, compressed decoction pieces and instant decoction pieces. Integration of treatment and processing at the place of origin is emerging. However, there is still room for improvement, for example, the manufacturing technologies of CMMDPs industry need to be continually improved. The management of CMMDPs' normalized production also needs to be strengthened. The quality of CMMDPs should be strengthened supervision and it should establish the objective and feasible quality evaluation system for CMMDPs. At present, China has attached unprecedented importance to the development of TCM, and issued a number of supporting policies, sparing no effort to support its development.

Abstract
Abstract
Study question
For X-autosome translocation [t(X-A)] carriers, is it a more applicable preimplantation genetic testing (PGT) strategy, that distinguishing noncarrier from euploid/ balanced embryos and prioritized transfer?
Summary answer
Noncarrier and carrier embryos discrimination in PGT is an applicable strategy to avoid transferring genetic and reproductive risks to the offspring of t(X-A) carriers.
What is known already
Balanced t(X-A) is a specific reciprocal translocation, with a higher risk of detrimental phenotype and fertility issues compared to individuals with autosomal translocation. Alternative X-chromosome inactivation (XCI) is a specific pathogenic mechanism in this population. For carrier offspring of couples with t(X-A), the genetic counseling is challenged in both the prenatal and postpartum stages, because of the complexity and severity of phenotype outcomes that are unpredictable and associated with the complex XCI mechanism. Therefore, caution is necessary when designing a PGT strategy for couples with t(X-A).
Study design, size, duration
A retrospective study. We collected a 3-year-old girl with maternal translocation 46,X,t(X;1)(q28;p31.1) presenting with multiple congenital disabilities. Three couples with female t(X-A) carrier requesting for PGT.
Participants/materials, setting, methods
Karyotype analysis, whole-exome sequencing (WES), and X inactivation analysis were performed for the girl with congenital cardiac anomaly, language defect, and mild neurodevelopmental delay. PGT based on next-generation sequencing following the microdissecting junction region to distinguish noncarrier and carrier embryos were used in three couples with female t(X-A) carrier (Cases 1–3).
Main results and the role of chance
The girl carried a maternal balanced translocation 46,X,t(X;1)(q28;p31.1). WES revealed none monogenic mutation related to her phenotype, but she carried a rare skewed inactivation of the translocation X chromosome and spread to the adjacent interstitial 1p segment, contrary to her mother. All translocation breakpoints of Cases 1–3 were successfully identified and each couple underwent one PGT cycle. Thirty oocytes were retrieved, and 13 blastocysts were eligible for biopsy, of which 6 (46.15%) embryos were balanced and only 4 were noncarriers. Three frozen embryo transfers with noncarrier embryos resulted in the birth of two healthy children (one girl and one boy), who were subsequently confirmed to have normal karyotypes. We reported a girl with multiple congenital disabilities resulting from maternally balanced t(X-A) and validated that noncarrier and carrier embryo discrimination is an effective and applicable strategy for avoiding transferring genetic and reproductive risks to the offspring from t(X-A) carriers.
Limitations, reasons for caution
Here, we reported a girl with multiple congenital disabilities resulting from maternally balanced t(X-A) found different XCI patterns, while we did not further determine the mechanism causing the different XCI patterns between the girl and her mother.
Wider implications of the findings: We demonstrated passing on a balanced t(X-A) may result in clinical manifestations associated with the X-inactivation, and verified the PGT strategy, that distinguishing normal and carrier embryos in can widely applied in t(X-A) carrier couples to avoid the genetic and reproductive risk of transferring t(X-A) to the next generation.

Abstract
Objectives: The present meta-analysis aimed to assess the relationship between antiphospholipid antibodies (aPLs) or antiphospholipid antibody syndrome (APS) and the incidence of osteonecrosis (ON) in systemic lupus erythematosus (SLE) patients.Methods: MEDLINE/Pubmed, EMBASE, Web of science, the Chinese Biomedical Literature Database (CBM), the Wan-Fang Database, and the China National Knowledge Infrastructure (CNKI) were searched from their inception up until 26 December 2020. Studies in English were included. Case-control studies and cohort studies were included. Studies pertaining to the link between aPLs or APS and ON patients were slated for inclusion in the current analysis.Results: Twenty-two studies involving a total of 3054 SLE patients were included. The positivities of anticardiolipin antibody (ACL), IgG ACL, IgM ACL, LA and APS in SLE is not associated with ON. One study showed that IgG or IgM β2GP1 had no association with ON. No publication bias was detected. The quality of this evidence was low because of the high risk of bias across studies, and therefore robust inferences cannot be made.Conclusion: SLE patients demonstrated a weak association between aPLs and ON. The nature of the association between aPLs and ON in SLE needs to be investigated in-depth in future research.

Abstract
Children suffering from neurologic cancers undergoing chemotherapy and radiotherapy are at high risk of reduced neurocognitive abilities likely via damage to proliferating neural stem cells (NSC). Therefore, strategies to protect NSCs are needed. We argue that induced cell-cycle arrest/quiescence in NSCs during cancer treatment can represent such a strategy. Here, we show that hyperpolarization-activated cyclic nucleotide-gated (HCN) ion channels are dynamically expressed over the cell cycle in NSCs, depolarize the membrane potential, underlie spontaneous calcium oscillations and are required to maintain NSCs in the actively proliferating pool. Hyperpolarizing pharmacologic inhibition of HCN channels during exposure to ionizing radiation protects NSCs cells in neurogenic brain regions of young mice. In contrast, brain tumor-initiating cells, which also express HCN channels, remain proliferative during HCN inhibition. IMPLICATIONS: Our finding that NSCs can be selectively rescued while cancer cells remain sensitive to the treatment, provide a foundation for reduction of cognitive impairment in children with neurologic cancers.

Abstract
Water is the only atmospheric parameter with three-phase state. An ultraviolet Raman lidar was developed for synchronous measurements for water vapor, liquid water and ice water in Xi’an University of Technology, Xi’an, China (34.233°N, 108.911°E). An accurate retrieval method on the basis of interference degree is proposed for synchronous three-phase water mixing ratio profiles. Preliminary measurements are carried out in the Laser Radar Center of Remote Sensing of Atmosphere (LRCRSA). Several representative examples are obtained and validated the performance of Raman system. Combined with atmospheric temperature profiles, the synchronous water vapor, liquid water and ice water profiling are retrieved and revealed the variation characteristics in three-phase water. The effective detection can reach up to a height of 5 km under cloudy weather, and synchronized growth in water vapor and liquid water content was obtained in cloud layers. Continuous observations are also made under haze weather condition, and the temporal and spatial evolution trend of three-phase water in clouds at 2 km altitude are successfully realized.

Abstract
BACKGROUND In ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PPCI), current oral P2Y12 platelet inhibitors do not provide maximal platelet inhibition at the time of reperfusion. Furthermore, administration of cangrelor prior to reperfusion has been shown in pre-clinical studies to reduce myocardial infarct (MI) size. Therefore, we hypothesize that cangrelor administered prior to reperfusion in STEMI patients will reduce the incidence of microvascular obstruction (MVO) and limit MI size in STEMI patients treated with PPCI. METHODS The platelet inhibition to target reperfusion injury (PITRI) trial, is a phase 2A, multi-center, double-blinded, randomized controlled trial, in which 210 STEMI patients will be randomized to receive either an intravenous (IV) bolus of cangrelor (30 μg/kg) followed by a 120-minute infusion (4 μg/kg/min) or matching saline placebo, initiated prior to reperfusion (NCT03102723). RESULTS The study started in October 2017 and the anticipated end date would be July 2020. The primary end-point will be MI size quantified by cardiovascular magnetic resonance (CMR) on day 3 post-PPCI. Secondary endpoints will include markers of reperfusion, incidence of MVO, MI size, and adverse left ventricular remodeling at 6 months, and major adverse cardiac and cerebrovascular events. SUMMARY The aim of the PITRI trial is to assess whether cangrelor administered prior to reperfusion would reduce acute MI size and MVO, as assessed by CMR.

Abstract
ATP (Adenosine triphosphate) is an important endogenous damage - associated molecular pattern (DAMP). P2X7R is an ATP-gated cation channel. ATP-P2X7R plays a vital role in the pathophysiology of many diseases because P2X7R is distributed on various immune cells. ATP-P2X7R signal transduction pathway has been implicated to participate in the body's immune defense against pathogens. This paper reviews the recent progress regarding ATP-P2X7R and its effects on parasitic diseases.

Abstract
The objective of the present study was to determine the composition of various layers of upper urinary stones and assess the mechanisms of stone nucleation and aggregation. A total of 40 integrated urinary tract stones with a diameter of >0.8 cm were removed from the patients. All of the stones were cut in half perpendicularly to the longitudinal axis. Samples were selected from nuclear, internal and external layers of each stone. Fourier transform infrared spectroscopy (FT-IR) was adopted for qualitative and quantitative analysis of all of the fragments and compositional differences among nuclear, internal and external layers of various types of stone were subsequently investigated. A total of 25 cases of calcium oxalate (CaOx) stones and 10 cases of calcium phosphate (CaP) stones were identified to be mixed stones, while 5 uric acid (UA) calculi were pure stones (purity, >95%). In addition, the contents of CaOx and carbapatite (CA.AP) crystals in various layers of the mixed stones were found to be variable. In CaOx stones, the content of CA.AP in nuclear layers was significantly higher than that of the outer layers (32.0 vs. 6.8%; P<0.05), while the content of CaOx was lower in the inner than in the outer layers (57.6 vs. 86.6%; P<0.05). In CaP stones, the content of CA.AP in the nuclear layers was higher than that in the outer layers (74.0 vs. 47.3%; P<0.05), while the content of CaOx was lower in the inner than in the outer layers (7.0 vs. 40.0%; P<0.05). The UA stones showed no significant differences in their composition among different layers. In conclusion, FT-IR analysis of various layers of human upper urinary tract stones revealed that CaOx and CaP stones showed differences in composition between their core and surface, while all of the UA calculi were pure stones. The composition showed a marked variation among different layers of the stones, indicating that metabolism has an important role in different phases of the evolution of stones. The present study provided novel insight into the pathogenesis of urinary tract stones and may contribute to their prevention and treatment.

Abstract
GOAL Hyperthermia therapy requires tight temperature control to achieve selective killing of cancerous tissue with minimal damage on surrounding healthy tissues. METHODS To this end, accurate temperature monitoring and subsequent heating control are critical. However, an economic, portable, and real-time temperature control solution is currently lacking. To bridge this gap, we present a novel portable close-loop system for hyperthermia temperature control, in which photoacoustic technique is proposed for noninvasive real-time temperature measurement. Exploiting the high sensitivity of photoacoustics, the temperature is monitored with an accuracy of around 0.18 °C and then fed back to a controller implemented on field programmable gate array (FPGA) for temperature control. Dubbed as portable hyperthermia feedback controller (pHFC), it stabilizes the temperature at preset values by regulating the hyperthermia power with a proportional-integral-derivative (PID) algorithm; and to facilitate digital implementation, the pHFC further converts the PID output into switching values (0 and 1) with the pulse width modulation (PWM) algorithm. RESULTS Proof-of-concept hyperthermia experiments demonstrate that the pHFC system is able to bring the temperature from baseline to predetermined value with an accuracy of 0.3° and a negligible temperature overshoot. CONCLUSION The pHFC can potentially be translated to clinical applications with customized hyperthermia system design. SIGNIFICANCE This paper can facilitate future efforts in seamless integration of close-loop temperature control solution and various clinical hyperthermia systems.

Abstract
Ammopiptanthus mongolicus, a woody plant growing in the desert, plays a vital role in vegetation maintaining and restoration in the arid region in northwest China. The plant exhibits an extremely high tolerance to abiotic stress such as drought and freezing stresses, and it has been used as an ideal model for abiotic stress tolerance research in trees. MicroRNA (miRNA) is a class of approximately 21nt endogenous non-protein-coding small RNA, which plays an important role in plant growth, development and responses to environmental stresses. By now, a large number of miRNAs have been reported in many plant species, but no studies describing A.mongolicus miRNA were published. In the present study, the types, expression levels, and putative target genes of conserved miRNAs in seedlings of A. mongolicus were analyzed using small RNA deep sequencing technology and bioinformatics methods. Nineteen conserved miRNAs, which belong to 10 miRNA families, were identified, with abundance ranging from 55 to 1920269 reads. Target prediction analysis determined the target genes of 14 conserved miRNAs. The functional classification analysis indicated that the conserved miRNAs participate in the development and environmental response by regulating the biological processes including the transcription regulation, hormone signal transduction, metabolisms and stress resistance.

Abstract
BACKGROUND AND PURPOSE To test a hypothesis that: (i) duodenal pH and osmolarity are individually controlled at constant set points by negative feedback control centred in the enteric nervous system (ENS); (ii) the purinergic P2Y(1) receptor subtype is expressed by non-cholinergic secretomotor/vasodilator neurons, which represent the final common excitatory pathway from the ENS to the bicarbonate secretory glands. EXPERIMENTAL APPROACH Ussing chamber and pH-stat methods investigated involvement of the P2Y(1) receptor in neurogenic stimulation of mucosal bicarbonate (HCO(3)(-)) secretion in guinea pig duodenum. KEY RESULTS ATP increased HCO(3)(-) secretion with an EC(50) of 160 nM. MRS2179, a selective P2Y(1) purinergic receptor antagonist, suppressed ATP-evoked HCO(3)(-) secretion by 47% and Cl(-) secretion by 63%. Enteric neuronal blockade by tetrodotoxin or exposure to a selective vasoactive intestinal peptide (VIP, VPAC(1)) receptor antagonist suppressed ATP-evoked HCO(3)(-) secretion by 61 and 41%, respectively, and Cl- by 97 and 70% respectively. Pretreatment with the muscarinic antagonist, scopolamine did not alter ATP-evoked HCO3(-) or Cl(-) secretion. CONCLUSION AND IMPLICATIONS Whereas acid directly stimulates the mucosa to release ATP and stimulate HCO(3)(-) secretion in a cytoprotective manner, neurogenically evoked HCO(3)(-) secretion accounts for feedback control of optimal luminal pH for digestion. ATP stimulates duodenal HCO(3)(-) secretion through an excitatory action at purinergic P2Y(1) receptors on neurons in the submucosal division of the ENS. Stimulation of the VIPergic non-cholinergic secretomotor/vasodilator neurons, which are one of three classes of secretomotor neurons, accounts for most, if not all, of the neurogenic secretory response evoked by ATP.

Abstract
BACKGROUND Chronic kidney disease (CKD) has been demonstrated to be associated with adverse clinical outcomes for patients with coronary artery disease (CAD). However, data on relation of CKD and stent thrombosis (ST) after drug-eluting stent (DES) implantation are limited. OBJECTIVES This study was designed to examine whether CKD is associated with higher incidence of ST after elective coronary DES implantation compared with patients with normal renal function. METHODS We consecutively enrolled 2,862 patients undergoing elective percutaneous coronary intervention (PCI) with DES. Demographic and clinical data were collected preoperatively. CKD was defined as estimated glomerular filtration rate (eGFR) < 60 ml/min, calculated using the modified MDRD equation. The primary outcome was 1-year definite or probable ST. RESULTS Four hundred and forty-five participants (15.5%) had CKD before procedure. The incidence of 1-year definite or probable ST was significantly higher in CKD patients compared with patients with normal renal function (1.8% vs. 0.6%, P = 0.014). After adjustment for multiple clinical and biochemical covariates, CKD was an independent predictor of 1-year definite or probable ST (hazard rate [HR] 0.396, 95% CI 0.165-0.951, P = 0.038). CONCLUSION CKD is significantly associated with increased incidence of 1-year definite or probable ST in patients undergoing PCI with DES.

Abstract
BACKGROUND AND PURPOSE To investigate whether brain iron deposition correlates with motor phenotypic expressions of Parkinson's disease. METHODS We subtyped patients with Parkinson's disease according to their main motor symptoms (tremor, rigidity/bradykinesia) into three subgroups: tremor-dominant subgroup, akinetic/rigid-dominant subgroup, or mixed subgroup. The iron levels in bilateral substantia nigra, globus pallidus, putamen, the head of caudate, and red nucleus of 87 patients and 50 control subjects were assayed by measuring phase values using susceptibility-weighted phase imaging in a 3-tesla magnetic resonance system. The serum ceruloplasmin levels of all subjects were determined. RESULTS The bilateral average phase values of the substantia nigra and all other brain regions examined did not correlate with the main motor symptoms of Parkinson's disease in the total patient group or when patients were grouped according to serum ceruloplasmin levels. Significant correlations between serum ceruloplasmin levels and nigral bilateral average phase values were observed in the tremor and akinetic/rigid-dominant subgroups. Analysis of patients without prior dopaminergic medication exhibited similar results. Increased nigral iron content correlated with disease severity as assayed by the Unified Parkinson's Disease Rating Scale motor scores in the PD(AR) subgroup. CONCLUSIONS These findings suggest that nigral iron deposition, correlating with decreased serum ceruloplasmin levels, is a risk factor in Parkinson's disease across multiple motor phenotypic expressions.

Abstract
Objective The aim of this study was to use fractal dimension (FD) analysis on multidetector CT (MDCT) images for quantifying the morphological changes of the pulmonary artery tree in patients with pulmonary hypertension (PH). Materials and Methods Fourteen patients with PH and 17 patients without PH as controls were studied. All of the patients underwent contrast-enhanced helical CT and transthoracic echocardiography. The pulmonary artery trees were generated using post-processing software, and the FD and projected image area of the pulmonary artery trees were determined with ImageJ software in a personal computer. The FD, the projected image area and the pulmonary artery pressure (PAP) were statistically evaluated in the two groups. Results The FD, the projected image area and the PAP of the patients with PH were higher than those values of the patients without PH (p < 0.05, t-test). There was a high correlation of FD with the PAP (r = 0.82, p < 0.05, partial correlation analysis). There was a moderate correlation of FD with the projected image area (r = 0.49, p < 0.05, partial correlation analysis). There was a correlation of the PAP with the projected image area (r = 0.65, p < 0.05, Pearson correlation analysis). Conclusion The FD of the pulmonary arteries in the PH patients was significantly higher than that of the controls. There is a high correlation of FD with the PAP.

Abstract
AIM OF THE STUDY This study aims to evaluate the association between hepatitis B virus (HBV) and lymphoma and to characterize HBV-related lymphomas. The efficacy of prophylactic lamivudine on HBV reactivation was also evaluated. METHODS We compared the prevalence rate of HBV infection in 556 patients with lymphoma seen over a 4-yr period with that in a group of 4698 Singapore residents aged 18-69 who participated in the National Health Survey. Next, we compared the clinic-pathologic characteristics of HBV-positive and HBV-negative lymphoma cases. RESULTS The prevalence rate of HBV infection in our study was 10.3% (57/556), higher than the prevalence rate of 4.1% (192/4698) in the general population (P < or = 0.001). The higher prevalence was observed in both sexes and across different age groups. An association was observed for non-Hodgkin's lymphoma (NHL) but not Hodgkin's lymphoma. The characteristics of HBV-infected patients with lymphoma were similar to those who were HBV-uninfected in terms of age, ECOG, extra-nodal involvement, LDH level, stage, complete remission rate and overall survival. Use of prophylactic lamivudine significantly decreased the incidence of HBV reactivation (13% vs. 38%, P = 0.02) and disruption to chemotherapy (43% vs. 4%, P = 0.02), with a trend towards improved overall survival. CONCLUSIONS Our findings suggest that an association exists between HBV infection and NHL. However, HBV infection does not appear to have a significant impact on the clinical characteristics and prognosis of NHL. Prophylactic lamivudine should be considered in all HBV-infected patients receiving antracycline and/or steroid containing chemotherapy.
