Abstract
Objective: To understand the situation and epidemic characteristics of injury deaths among children aged 5 to 24 years in Jiangsu Province from 2012 to 2021 and the trend of annual changes. Methods: The main injury mortality data of children and adolescents was collected, and the crude and standardized mortality rates of road traffic accidents, drowning, suicide, and accidental falls among children and adolescents over a decade and the annual average percentage of change (AAPC) were calculated. The main injury mortality characteristics and trends of children and adolescents of different age groups and genders were analyzed. Results: The total number of injury deaths among 5 to 24 adolescents in Jiangsu Province was 16 052, with a standardized mortality rate of 9.58/100 000. There was no significant trend in the overall standardized mortality rate of injuries (AAPC=-3.450%, P=0.055). The standardized mortality rate of road traffic injuries among children and adolescents showed a decreasing trend over the past decade, with statistical significance (AAPC=-9.406%, P<0.001). The standardized suicide mortality rate showed an upward trend over the past decade, with statistical significance (AAPC=9.000%, P=0.001). The overall injury mortality rate showed an upward trend with age. Suicide rates in males and females were on the rise and both have statistical significance (AAPC=9.420% and AAPC=9.607%, both P<0.05). The standardized mortality rates of female traffic accidents, drowning, and male traffic accidents showed a decreasing trend and were statistically significant (AAPC for female traffic accidents=-7.364%, AAPC for female drowning=-5.352%, and AAPC for male traffic accidents=-10.242%, all P<0.05). The standardized mortality rate of urban and rural traffic accidents showed a decreasing trend and was statistically significant(AAPC=-7.899% and AAPC=-9.421%, both P<0.001). The standardized suicide mortality rate showed an upward trend and statistical significance (AAPC=11.009% and AAPC=7.528%, both P<0.05). Conclusions: The overall injury situation of children and adolescents in Jiangsu Province improved in the past decade from 2012 to 2021, but the suicide mortality rate was on the rise. It is necessary to focus on the mental health issues of this age group and to strengthen the prevention and control of suicide among children and adolescents, in Jiangsu.

Abstract
Dengue virus (DENV) infection remains a challenging health threat worldwide. Ubiquitin-specific protease 18 (USP18), which preserves the anti-interferon (IFN) effect, is an ideal target through which DENV mediates its own immune evasion. However, much of the function and mechanism of USP18 in regulating DENV replication remains incompletely understood. In addition, whether USP18 regulates DENV replication merely by causing IFN hyporesponsiveness is not clear. In the present study, by using several different approaches to block IFN signaling, including IFN neutralizing antibodies (Abs), anti-IFN receptor Abs, Janus kinase inhibitors and IFN alpha and beta receptor subunit 1 (IFNAR1)knockout cells, we showed that USP18 may regulate DENV replication in IFN-associated and IFN-unassociated manners. Localized in mitochondria, USP18 regulated the release of mitochondrial DNA (mtDNA) to the cytosol to affect viral replication, and mechanisms such as mitochondrial reactive oxygen species (mtROS) production, changes in mitochondrial membrane potential, mobilization of calcium into mitochondria, 8-oxoguanine DNA glycosylase 1 (OGG1) expression, oxidation and fragmentation of mtDNA, and opening of the mitochondrial permeability transition pore (mPTP) were involved in USP18-regulated mtDNA release to the cytosol. We therefore identify mitochondrial machineries that are regulated by USP18 to affect DENV replication and its association with IFN effects.

Abstract
Objective: To investigate the familial heritability of endometriosis and to compare the clinical characteristics of patients with or without a family history of endometriosis. Methods: From January 2020 to June 2022, 850 patients with endometriosis confirmed by laparotomy or laparoscopy in Peking University Third Hospital were included in this study. Clinical data were collected, family history was followed up, and the differences of clinical indicators between patients with and without family history of endometriosis were compared. Results: A total of 850 patients were enrolled, with an average age of (33.8±7.0) years old, 315 (37.1%, 315/850) patients in stage Ⅲ and 496 (58.4%, 496/850) patients in stage Ⅳ. There were 100 patients with family history of endometriosis, accounting for 11.8% (100/850). Most of the 113 relatives involved were mothers, daughters and sisters (76.1%, 86/113), 81.5% (22/27) of the second and third degree relatives were maternal relatives. The median ages of patients with and without family history of endometriosis were 30 and 33 years old respectively at the time of diagnosis. The unmarried rate of patients with family history was higher [42.0% (42/100) vs 26.3% (197/750)]. The percentage of dysmenorrhea patients with family history was higher [89.0% (89/100) vs 55.5% (416/750)]. The medians of dysmenorrhea score in patients with and without family history were 6 and 2, and the median durations of dysmenorrhea were 10 and 1 years. There were significant differences in age, marital status, percentage of dysmenorrhea, dysmenorrhea score and duration (all P<0.001). The median levels of serum cancer antigen (CA) 125 in patients with family history and patients without family history at the time of diagnosis were 57.5 and 46.9 kU/L respectively, with a statistically significant difference (P<0.05). However, there were no significant differences between the two groups in nationality, bady mass index, menarche age, menstrual cycle, menstrual period, menstrual volume, serum CA19-9 level, cyst location and size, stage, history of adverse pregnancy and childbirth, infertility, adenomyosis and deep infiltrating endometriosis (all P>0.05). By comparing the specific conditions of dysmenorrhea patients with and without family history of endometriosis, there were no significant differences between the two groups in terms of the age of onset of dysmenorrhea, duration of dysmenorrhea, primary and secondary dysmenorrhea, and progressive aggravation of dysmenorrhea (all P>0.05). The difference in the degree of dysmenorrhea in dysmenorrhea patients with family history of endometriosis was significant (P<0.001). Conclusions: The incidence of endometriosis has a familial tendency, and most of the involved relatives are the first degree relatives. Compared with patients without family history of endometriosis, endometriosis patients with family history are diagnosed at an earlier age, with higher percentage of dysmenorrhea, had more severe dysmenorrhea and higher serum CA125 level.

Abstract
Continuous wave dual-wavelength lasers at 1342 and 1525 nm are developed by using separate Nd:YVO4 and YVO4 crystals to form compactly coupled cavities for fundamental and Raman waves, respectively. The design of the coupled cavity not only reduces the thermal lensing effect in the Nd:YVO4 crystal, but also improves the stimulated Raman scattering (SRS) efficiency in the undoped YVO4 crystal. In addition, the Raman crystal is coated to form a highly reflective mirror to minimize cavity losses. By using a plano-concave cavity with a pump power of 40 W, the output powers of the fundamental and Raman waves are 470 mW and 310 mW, respectively. Changed to a concave cavity, the output powers of fundamental and Raman waves are 220 mW and 510 mW, respectively. Basis on the dual-wavelength operation, the maximum output power at 714 nm can reach 2.0 W via the sum frequency generation. A light source at 714 nm can be used for laser spectroscopy of atomic and ionic radium isotopes.

Abstract
Objective: To investigate the clinical value of the bipolar tweezers-clamp for the hepatic parenchymal transection in the resection of hepatocellular carcinoma. Methods: From January 2020 to January 2021,63 patients with the hepatocellular carcinoma for hepatectomy at Department of Hepatopancreatobiliary Surgery,Yuebei People's Hospital Affiliated to Shantou University Medical College were analyzed retrospectively.According to the different instruments used in the hepatic parenchymal transection,the patients were divided into bipolar tweezers-clamp group and ultrasonic scalpel group.There were 32 patients in bipolar tweezers-clamp group,with age of (55.5±10.5)years(range:37 to 78 years),including 22 males and 10 females,tumor size was (6.0±3.4)cm(range:2.4 to 13.4 cm). There were 6 patients with portal vein tumor thrombus and 5 patients with portal hypertension. There were 31 patients in ultrasonic scalpel group,with aged(57.8±10.1)years(range:37 to 79 years),including 27males and 4 females,tumor size was(7.9±5.1)cm(range: 2.4 to 21.3 cm),3 patients with portal vein tumor thrombus and 2 patients with portal hypertension. The preoperative baseline data,operation time,blood loss,postoperative liver function and the complications were compared between two groups using t test,χ2 test and Fisher exact probabilityrespectively. Results: The operation was successfully completed in both groups.Compared with the ultrasonic scalpel group,the operation time was significantly shorter((219.3±76.4)minutes vs.(294.0±100.8)minutes,t=-3.322,P=0.002),the blood loss was less((250(475)ml vs. 500(1 050)ml,t=-2.307,P=0.026),the concentrate red blood cells transfusion volume was less(0.92(0.88)U vs. 2.32(4.00)U,Z=-1.987,P=0.047) in the bipolar tweezers-clamp group.The postoperative serum ALB level was higher in the bipolar tweezers-clamp group than that in the ultrasonic scalpel group((33.5±6.1)g/L vs. (29.5±4.2)g/L,t=3.226,P=0.020) on postoperative day 1;((35.7±4.5)g/L vs.(30.1±3.2)g/L,t=5.575,P<0.01) on postoperative day 3;((33.2±3.7)g/L vs. (31.0±4.4)g/L,t=3.020,P=0.004) on postoperative day 7. There was no significant difference in serum ALT,TBIL and PT level between the two groups(all P>0.05).No postoperative bile leakage occurred in both groups.The postoperative complications occurred in 8 cases(25.0%)in the bipolar tweezers-clamp group,including liver failure in one,and in 11 cases(35.5%)in the ultrasonic scalpel group,including liver failure in two(P>0.05). Conclusion: The bipolar tweezers-clamp is a safe and reliable method for the hepatic parenchymal transaction,which is quick and less bleeding during the hepatic resection.

Abstract
Objective: To analyze the clinical characteristics and prognostic value of liver function in a large samples of patients with anti-glycoprotein 210 (gp210 antibody) positive primary biliary cholangitis (PBC). Methods: A retrospective study was performed on 931 PBC cases in Beijing You'an Hospital affiliated to Capital Medical University from 2010 to 2019. According to the detection of gp210 antibody, 318 cases were divided into gp210 antibody positive group (positive group) and 613 cases were divided into gp210 antibody negative group (negative group). The differences in demographic, medical history, clinical indicators, B-ultrasound and pathological indicators as well as the histopathological basis were compared between the two groups. SPSS 16.0 software was used for statistical analysis. Measurement data were analyzed by t-test or rank sum test, and enumeration data by χ2 test. Multivariate analysis was used for logistic test, and and survival analysis was used for prognosis. Results: The positive and the negative groups were compared. The ratio of male to female was significantly higher in positive than negative group (1:5.35 vs. 1:9.73, P<0.05), and the difference was statistically significant. The proportion of hormone use in history of past diagnosed and treated was higher in positive than negative group (12.9% vs. 3.47%, P<0.05), and the difference was statistically significant. The detection of biochemical indexes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT) were higher in positive than the negative group (51.1 U/L vs. 41.1 U/L, 62.6 U/L vs. 49.6 U/L, 24.1 μmol/L vs. 17.9 μmol/L, 228.3 U/L vs. 169.6 U/L, 203.9 U/L vs. 147.6 U/L), (P<0.05), and the differences were statistically significant. Antinuclear antibody (ANA)-positive rate, high titer ratio and immunoglobulin G (IgG) levels were higher in positive than negative group (95.2% vs. 81.6%, 69.7% vs. 48.8%, 17.2 g/L vs. 16.2 g/L), (P<0.05), and the differences were statistically significant. The incidence of liver failure was higher in positive than negative group (P<0.05). CK7 and inflammation score were higher in positive group than negative group in liver histopathological observations (0.83±0.53 vs. 0.28±0.47; 1.06±0.39 vs. 0.54±0.65), (P<0.05), and the differences were statistically significant. Conclusion: The illness condition of patients with gp210 antibody positive PBC is more severe than patients with gp210 antibody negative PBC, and the incidence of liver failure is significantly increased. Cholangiocytes may be the histopathological basis of the clinical characteristics of gp210 antibody positive PBC patients.

Abstract
Objective: To analyze the characteristics of clinical and laboratory indexes in patients with liver disease with positive anti-liver cytosol antibody type 1 (anti-LC1), in order to provide references for clinical and differential diagnosis. Methods: The clinical data of 23 832 inpatients and outpatients with positive anti-LC1 autoantibodies detected in routine autoantibody test from January 2010 to January 2020 were retrospectively analyzed, and their clinical and laboratory indexes were compared. Western blotting was used to detect anti-LC1, anti-soluble liver antigen antibody (anti-SLA), anti-glycoprotein 210 antibodies and anti-nucleosome 100 antibodies. Indirect immunofluorescence assay was used to detect anti-nuclear antibody (ANA), anti-mitochondrial antibody, anti-Smooth muscle antibody (ASMA), anti-liver and kidney microsomal antibody (anti-LKM) and other autoantibodies. Normally distributed measurement data between the two groups were compared by independent-sample t-test, and the multiple groups comparison were compared by one-way analysis of variance. Non-normally distributed measurement data were compared by non-parametric rank sum test. Results: 38 anti-LC1 positive patients were detected in 23832 autoantibody tests. The age of initial diagnosis ranged from 11.0 to 84.0 (50.6 ± 16.0) years. There were 8 males (21.1%) and 30 females (78.9%). A total of 31 cases (81.6%) were positive for anti-LC1 and ANA, and the dominant karyotype was speckled pattern, accounting for 54.8%. Five cases (13.2%) were positive for ASMA, and no simultaneous positive with anti-LKM or anti-SLA. Among the 38 anti-LC1 positive patients, 9 were diagnosed with autoimmune hepatitis (AIH), 6 with possible AIH, 6 with primary biliary cholangitis (PBC), 8 with hepatitis B, 2 with hepatitis C, 1 with alcoholic liver disease, 2 with non-alcoholic fatty liver disease, 1 with drug-induced liver injury, 1 with hepatolenticular degeneration, and 2 with tumor. Confirmed and probable AIH cases accounted for 39.5% (15/38) of anti-LC1 positive cases. Among anti-LC1 positive patients, 47.4% (18/38) had entered the stage of liver cirrhosis. AIH group globulin level was higher than HBV group (P = 0.006) and other disease groups (P = 0.001). AIH group IgG level was higher than PBC group (P = 0.027), HBV group (P = 0.009) and other disease groups (P = 0.004). the of the PBC group IgM level was higher than AIH group (P = 0.003), HBV group (P = 0.003) and other disease groups (P = 0.006). Conclusion: Anti-LC1 is not only detected in AIH, but also observed in patients with primary biliary cholangitis, hepatitis B and C, alcoholic and non-alcoholic liver disease, drug-induced liver injury, hereditary metabolic liver disease and tumor. In addition, it is mainly female gender dominance and nearly half of ANA-positive young, middle-aged and elderly patients develop liver cirrhosis. For the diagnosis of type 2 autoimmune hepatitis, whether anti-LC1 is a specific antibody needs further research, but if AIH is highly suspected, this antibody can be used as a substitute.

Abstract
Synchrony Respiratory Tracking system adapted from CyberKnife has been introduced in Radixact to compensate the tumor motion caused by respiration. This study aims to compare the modeling accuracy of the Synchrony system between Radixact and CyberKnife. Two Synchrony plans based on fiducial phantoms were created for CyberKnife and Radixact, respectively. Different respiratory motion traces were used to drive a motion platform to move along the superoinferior and left-right direction. The cycle time and the amplitude of target/surrogate motion of one selected motion trace were scaled to investigate the dependence of modeling accuracy on the motion characteristic. The predicted target position, the correlation error, potential difference (Radixact only) and standard error (CyberKnife only) were extracted from raw data or log files of the two systems. The modeling accuracy was evaluated by calculating the root-mean-square (RMS) error between the predicted target positions and the input motion trace. A threshold T95 within which 95% of the potential difference or the standard error lay was defined and evaluated. Except for the motion trace with a small amplitude and a good (linear) correlation between target and surrogate motion, Radixact showed smaller RMS errors than CyberKnife. The RMS error of both systems increased with the motion amplitude and showed a decreasing trend with the increasing cycle time. No correlation was found between the RMS error and the amplitude of surrogate motion. T95 could be a good estimator of modeling accuracy for CyberKnife rather than Radixact. The correlation error defined in Radixact were largely affected by the number of fiducial markers and the setup error. In general, the modeling accuracy of the Radixact Synchrony system is better than that of the CyberKnife Synchrony system under unfavorable conditions.

Abstract
Escherichia coli Nissle (EcN), a probiotic bacterium protects against several disorders. Multiple reports have studied the pathways involved in cardiac hypertrophy. However, the effects of probiotic EcN against diabetes-induced cardiac hypertrophy remain to be understood. We administered five weeks old Wistar male (271±19.4 g body weight) streptozotocin-induced diabetic rats with 109 cfu of EcN via oral gavage every day for 24 days followed by subjecting the rats to echocardiography to analyse the cardiac parameters. Overexpressed interleukin (IL)-6 induced the MEK5/ERK5, JAK2/STAT3, and MAPK signalling cascades in streptozotocin-induced diabetic rats. Further, the upregulation of calcineurin, NFATc3, and p-GATA4 led to the elevation of hypertrophy markers, such as atrial and B-type natriuretic peptides. In contrast, diabetic rats supplemented with probiotic EcN exhibited significant downregulated IL-6. Moreover, the MEK5/ERK5 and JAK2/STAT3 cascades involved during eccentric hypertrophy and MAPK signalling, including phosphorylated MEK, ERK, JNK, and p-38, were significantly attenuated in diabetic rats after supplementation of EcN. Western blotting and immunofluorescence revealed the significant downregulation of NFATc3 and downstream mediators, thereby resulting in the impairment of cardiac hypertrophy. Taken together, the findings demonstrate that supplementing probiotic EcN has the potential to show cardioprotective effects by inhibiting diabetes-induced cardiomyopathies.

Abstract
Mitochondria regulate the immune response after dengue virus (DENV) infection. Microarray analysis of genes identified the upregulation of mitochondrial cytidine/uridine monophosphate kinase 2 (CMPK2) by DENV infection. We used small interfering RNA-mediated knockdown (KD) and CRISPR-Cas9 knockout (KO) approaches, to investigate the role of CMPK2 in mouse and human cells. The results showed that CMPK2 was critical in DENV-induced antiviral cytokine release and mitochondrial oxidative stress and mitochondrial DNA release to the cytosol. The DENV-induced activation of Toll-like receptor (TLR)-9, inflammasome pathway, and cell migration was suppressed by CMPK2 depletion; however, viral production increased under CMPK2 deficiency. Examining mouse bone marrow-derived dendritic cells from interferon-alpha (IFN-α) receptor-KO mice and signal transducer and activator of transcription 1 (STAT1)-KO mice, we confirmed that CMPK2-mediated antiviral activity occurred in IFN-dependent and IFN-independent manners. In sum, CMPK2 is a critical factor in DENV-induced immune responses to determine innate immunity.

Abstract
Purpose. This study aims to evaluate the performance of a commercial 1.5 T MR-Linac by analyzing its patient-specific quality assurance (QA) data collected during one full year of clinical operation.Methods and Materials. The patient-specific QA system consisted of offline delivery QA (DQA) and online calculation-based QA. Offline DQA was based on ArcCHECK-MR combined with an ionization chamber. Online QA was performed using RadCalc that calculated and compared the point dose calculation with the treatment planning system (TPS). A total of 24 patients with 189 treatment fractions were enrolled in this study. Gamma analysis was performed and the threshold that encompassed 95% of QA results (T95) was reported. The plan complexity metric was calculated for each plan and compared with the dose measurements to determine whether any correlation existed.Results. All point dose measurements were within 5% deviation. The mean gamma passing rates of the group data were found to be 96.8 ± 4.0% and 99.6 ± 0.7% with criteria of 2%/2mm and 3%/3mm, respectively. T95 of 87.4% and 98.2% was reported for the overall group with the two passing criteria, respectively. No statistically significant difference was found between adaptive treatments with adapt-to-position (ATP) and adapt-to-shape (ATS), whilst the category of pelvis data showed a better passing rate than other sites. Online QA gave a mean deviation of 0.2 ± 2.2%. The plan complexity metric was positively correlated with the mean dose difference whilst the complexity of the ATS cohort had larger variations than the ATP cohort.Conclusions. A patient-specific QA system based on ArcCHECK-MR, solid phantom and ionization chamber has been well established and implemented for validation of treatment delivery of a 1.5 T MR-Linac. Our QA data obtained over one year confirms that good agreement between TPS calculation and treatment delivery was achieved.

Abstract
Background Premature atherosclerosis occurs in patients with SLE; however, the mechanisms remain unclear. Both mitochondrial machinery and proinflammatory cytokine interferon alpha (IFN-α) potentially contribute to atherogenic processes in SLE. Here, we explore the roles of the mitochondrial protein cytidine/uridine monophosphate kinase 2 (CMPK2) in IFN-α-mediated pro-atherogenic events. Methods Foam cell measurements were performed by oil red O staining, Dil-oxLDL uptake and the BODIPY approach. The mRNA and protein levels were measured by qPCR and Western blotting, respectively. Isolation of CD4+ T cells and monocytes was performed with monoclonal antibodies conjugated with microbeads. Manipulation of protein expression was conducted by either small interference RNA (siRNA) knockdown or CRISPR/Cas9 knockout. The expression of mitochondrial reactive oxygen species (mtROS) was determined by flow cytometry and confocal microscopy. Results IFN-α enhanced oxLDL-induced foam cell formation and Dil-oxLDL uptake by macrophages. In addition to IFN-α, several triggers of atherosclerosis, including thrombin and IFN-γ, can induce CMPK2 expression, which was elevated in CD4+ T cells and CD14+ monocytes isolated from SLE patients compared to those isolated from controls. The analysis of cellular subfractions revealed that CMPK2 was present in both mitochondrial and cytosolic fractions. IFN-α-induced CMPK2 expression was inhibited by Janus kinase (JAK)1/2 and tyrosine kinase 2 (Tyk2) inhibitors. Both the knockdown and knockout of CMPK2 attenuated IFN-α-mediated foam cell formation, which involved the reduction of scavenger receptor class A (SR-A) expression. CMPK2 also regulated IFN-α-enhanced mtROS production and inflammasome activation. Conclusions The study suggests that CMPK2 plays contributing roles in the pro-atherogenic effects of IFN-α.

Abstract
Alzheimer's disease (AD) is characterized by memory dysfunction, Aβ plaques together with phosphorylated tau-associated neurofibrillary tangles. Unfortunately, the present existing drugs for AD only offer mild symptomatic cure and have more side effects. As such, developments of effective, nontoxic drugs are immediately required for AD therapy. Present study demonstrates a novel role of Chinese medicine prescription Yuan-Hu Zhi Tong (YZT) in treating AD, and it has substantiated the in vivo effectiveness of YZT in two different transgenic mice models of AD, namely P301S tau and 3XTg-AD mice. Oral treatment of YZT significantly ameliorates motor dysfunction as well as promotes the clearance of aggregated tau in P301S tau mice. YZT improves the cognitive function and reduces the insoluble tau aggregates in 3XTg-AD mice model. Furthermore, YZT decreases the insoluble AT8 positive neuron load in both P301S tau and 3XTg-AD mice. Using microarray and the "Connectivity Map" analysis, we determined the YZT-induced changes in expression of signaling molecules and revealed the potential mechanism of action of YZT. YZT might regulate ubiquitin proteasomal system for the degradation of tau aggregates. The research results show that YZT is a potential drug candidate for the therapy of tau pathogenesis and memory decline in AD.

Abstract
From 1987 to 2017, cardiovascular disease (CVD) had been ranking the first cause of death in Suzhou, and the mortality rate showed an upward trend annual percentage changes (APC=0.62%, P=0.001), while the standardized mortality rate showed a downward trend (APC=-2.65%, P<0.001). The probability of premature death of CVD declined consistently from 7.06% in 1987 to 2.00% in 2017 (APC=-4.45%, P<0.001). When the life expectancy was set at 70, the potential years of life lost rate (PYLLR) decreased from 6.35‰ in 1987 to 3.30‰ in 2017, and the standardized PYLLR decreased from 7.30‰ to 2.68‰. When the life expectancy was set at 75, the PYLLR decreased from 10.12‰ to 5.19‰, and the standardized PYLLR decreased from 11.44‰ to 3.88‰. With the increase of years, all PYLLR and standardized PYLLR showed a significantly downward trend (APC=-2.51%--3.89%, P<0.001).

Abstract
Abstract
Introduction
The pathophysiology of HFpEF is complicated and treatments that improve outcomes in HFrEF have no substantial benefits in HFpEF. Impairments in LV global longitudinal strain (GLS) and LV diastolic function parameters have been regarded as novel echocardiographic markers to predict cardiovascular events in HFpEF. Preliminary trials indicate that iloprost, an inhaled prostacyclin analougue, improves exercise hemodynamics in both patients with pulmonary artery hypertension and pulmonary hypertension associated with HFpEF.
Purpose
We aim to investigate the impact of inhaled iloprost on LV global longitudinal strain, LV diastolic function and RV function during exercise in HFpEF population.
Methods
34 patients diagnosed with HFpEF were included with exclusion of severe pulmonary, coronary artery, valvular heart and pericardial diseases. Subjects were randomized 1:1 to inhalation of iloprost or placebo. Transthoracic echocardiography was performed at rest and after 6-minute supine bicycle exercise at 20-Watt workload. We utilized tissue speckle tracking by QLAB software to derive LV GLS and global strain rate during LV isovolumetric relaxation period (SRIVR). E/e', E/SRIVR, tricuspid regurgitation pressure gradient (TRPG), tissue Doppler imaging of RV lateral tricuspid annulus and tricuspid annular plane systolic excursion (TAPSE) were measured to evaluate changes of myocardial performance.
Results
LV GLS during exercise significantly enhanced after iloprost use. E/SRIVR, a novel predictor of LV filling pressure, was significantly decreased. E/e' was also lower in iloprost group by trend. Improvements in RV function and degree of pulmonary hypertension during exercise with iloprost were observed in this study.

Effects of iloprost at rest and exercise
Conclusions
Our study is the first to demonstrate that, in patients with HFpEF, inhaled iloprost favorably enhances LV GLS reserves, decreases LV diastolic filling load, reduces pulmonary hypertension and thereby improves RV function during exercise.

Abstract
OBJECTIVE To evaluate the sero-positivity of Babesia infection in voluntary blood donors in Jiangsu region, so as to provide the evidence for transfusion safety. METHODS A total of 950 blood samples were collected from voluntary blood donors in Jiangsu Provincial Blood Center from February to May, 2017, and detected by double antigen sandwich ELISA targeting peptides derived from B. microti-secreted antigen 1 (BmSA1). The positive samples were confirmed by microscopy and nested-PCR to determine parasitemia. The prevalence of anti-BmSA1 was analyzed between/among different genders, ages and occupations of the blood donors. RESULTS Of the 950 blood screened samples, 5 were positive for anti-BmSA1, and the sero-prevalence of Babesia infection was 0.53%. The 5 samples were all negative by microscopy and nested-PCR. There were no gender- (χ2 = 0.01, P =0.92) or age-specific differences (χ2 = 0.11, P = 0.95) in the sero-prevalence of Babesia infection; however, there was an occupation-specific difference detected in the sero-prevalence of Babesia infection (χ2 = 11.93, P < 0.05). CONCLUSIONS Babesia infection is detected in voluntary blood donors in Jiangsu region, which should be paid much attention.

Abstract
In order to facilitate the treatment strategies for biliary tract injury, hilar cholangiocarcinoma, bile duct tumor thrombus, cholangiocellular carcinoma and bile duct cystic dilatation, many classifications have been made, even more than 10 types for one disease. Each type is represented by numbers or English alphabet, which are not only confusing but also difficult to remember. The Academician Mengchao Wu divided the liver into five sections and four segments base on its anatomy, this classification is very direct and visual, thus had been using till now. In order to overcome those complicated problems, it is considered to develop a new classification based on actual anatomic location similar to that for liver cancer, which is easy to remember and to directly determine the treatment strategy. All kinds of classifications have their own characteristics and advantages and disadvantages. This practical classifications avoid the complexity and may be useful for clinicians.

Abstract
Applications of wavelet analysis in ultra-thin film transient reflectivity (TR) measurements have been investigated. Advantages of utilizing different localized wavelet bases, in position and time, have been addressed on the residual TR signals. Morse wavelets have been used to obtain information from the abrupt oscillatory modes in the signal, which are not distinguishable with conventional methods such as Fourier transforms. These abrupt oscillatory modes are caused by the surface, interface, or any short-lived oscillatory modes which are suppressed in the TR signal in ultra-thin films. It is demonstrated that by choosing different Morse wavelets, information regarding different oscillatory modes in the TR signal of a heterostructure thin film is achievable. Moreover, by performing wavelet analysis on multiferroic heterostructures, oscillatory modes with very close energy ranges are easily distinguishable. For illustration, residuals of the TR signals have been obtained by a pump-probe setup in reflectivity mode on La0.7Sr0.3MnO3/SrTiO3 and BaTiO3/La0.7Sr0.3MnO3/SrTiO3 samples, where sufficient signal to noise ratios have been achieved by taking multiple scans. The residual signals have been analyzed with Morse wavelets, and multiple oscillatory modes with close energy ranges have been observed and distinguished. This approach can isolate the location of various oscillatory modes at the surface, interface and in the bulk of the heterostructure sample.

Abstract
OBJECTIVES To analyze the characteristics of medical malpractices in orthopaedic surgeries, to explore principles and methods in medical legal identification, and to provide basic data for uniform medicolegal standard for the future medical identification. METHODS A retrospective analysis was conducted on 100 cases of medical malpractices in orthopaedic surgery, among the 364 cases archived in Medicolegal Expertise Center of Xi'an Jiaotong University during 2002-2015. RESULTS In the 100 cases of orthopedic medical malpractices, with 104 hospitals involved in, 95 cases were judged with medical errors and the other 9 cases with no error. The top 3 reasons for errors were (1) inadequate observation or estimation of diseases (27.9%), (2) intraoperative improper operation (17.3%), and (3) delayed or missed diagnosis and treatment (12.5%). The consequences of medical malpractices were mostly disability (61%), followed by prolonged diseases (31%) and death (8%). With regard to the causal relationship between medical errors and consequences, 95 cases (91.4%) were with causality and the other 9 cases (8.6%) with no causality. Specifically, 56 cases (53.9%) were with medical errors as the secondary causes accounting for 25% causative potency, and 20 cases (19.2%) were with medical errors as the major causes accounting for 75% causative potency. CONCLUSIONS It is pivotally important for determining the causative potency of medical errors to analyse the causes of damages in orthopaedic surgery and to distinguish subjective factors from objective ones of medical errors.

Abstract
Objective: To investigate the prognostic risk factors of acquired immunodeficiency syndrome (AIDS) patients with pneumocystis pneumonia (PCP), and to establish risk models for predicting early outcome. Methods: The clinical data of 418 AIDS patients with PCP admitted to Department of Infectious Diseases, Beijing You'an Hospital, Capital Medical University from January 2008 to May 2016 were retrospectively analyzed.The patients were divided into death group and survival group according to clinical outcome during hospitalization.Data of the two groups were collected including general information and laboratory test results.Multivariate Logistic regression was used to analyze risk factors affecting prognosis of patients, establish prognostic models and evaluate predictive value of the model. Results: Of the 418 AIDS patients with PCP, 388 cases were male and 30 cases were female, aged from 5 to 82 years, mean age was (40±12) years.There were 82 patients in the death group and 336 patients in the survival group.Disease course, bacterial infection and alveolar-arterial oxygen pressure difference(P(A-a)O(2)), serum lactate dehydrogenase(LDH), white blood cell (WBC), neutrophil (N), alanine aminotransferase (AST), urea nitrogen (BUN) and serum potassium (K) were significantly higher in the death group than those in the survival group (all P<0.05), and arterial oxygen pressure (PaO(2)), blood oxygen saturation (SpO(2)), CD4(+) T lymphocyte count, lymphocyte (L) , hemoglobin (Hb), platelet (PLT), albumin (ALB), prealbumin (PALB), cholinesterase (CHE), cholesterol (CHO), serum chlorine (Cl) and serum sodium (Na) were significantly lower in the death group than those in the survival group (all P<0.05). Multivariate Logistic regression analysis showed that P(A-a)O(2, )ALB, LDH, N and CD4(+) T lymphocyte count were prognostic factors of AIDS complicated with PCP.Prognostic index=9.736+ 0.112×P(A-a)O(2)-0.719×ALB+ 0.006×LDH+ 0.355×N-0.021×CD4.ROC curve of the short-term prognostic model was 0.985 (95%CI 0.977-0.994), with P value 0.000, cut-off value 0.907, sensitivity 92.0% and specificity 98.8%.The mortality rate increased with the increase of equation value. Conclusions: P(A-a)O(2, )ALB, LDH, N and CD4(+) T lymphocyte count are independent risk factors to predict short-term prognosis in these patients.The short-term prognostic model based on independent risk factors is useful in guiding clinical treatment.

Abstract
PURPOSE Aerobic exercise improves prognosis and quality of life (QoL) following completion of chemotherapy. However, the safety and efficacy of aerobic exercise during chemotherapy is less certain. A systematic review was performed of randomised trials of adult patients undergoing chemotherapy, comparing an exercise intervention with standard care. METHOD From 253 abstracts screened, 33 unique trials were appraised in accordance with PRISMA guidance, including 3257 patients. Interventions included walking, jogging or cycling, and 23 were of moderate intensity (50-80% maximum heart rate). RESULTS Aerobic exercise improved, or at least maintained fitness during chemotherapy. Moderately intense exercise, up to 70-80% of maximum heart rate, was safe. Any reported adverse effects of exercise were mild and self-limiting, but reporting was inconsistent. Adherence was good (median 72%). Exercise improved QoL and physical functioning, with earlier return to work. Two out of four studies reported improved chemotherapy completion rates. Four out of six studies reported reduced chemotherapy toxicity. There was no evidence that exercise reduced myelosuppression or improved response rate or survival. CONCLUSIONS Exercise during chemotherapy is safe and should be encouraged because of beneficial effects on QoL and physical functioning. More research is required to determine the impact on chemotherapy completion rates and prognosis.

Abstract
Toll-like receptors (TLRs) are important sensors that recognize pathogen-associated molecular patterns. Generally, TLR9 is known to recognize bacterial or viral DNA but not viral RNA and initiate an immune response. Herein, we demonstrate that infection with dengue virus (DENV), an RNA virus, activates TLR9 in human dendritic cells (DCs). DENV infection induces release of mitochondrial DNA (mtDNA) into the cytosol and activates TLR9 signaling pathways, leading to production of interferons (IFNs). The DENV-induced mtDNA release involves reactive oxygen species generation and inflammasome activation. DENV infection disrupts the association between transcription factor A mitochondria (TFAM) and mtDNA and activates the mitochondrial permeability transition pores. The side-by-side comparison of TLR9 and cyclic GMP-AMP synthase (cGAS) knockdown reveals that both cGAS and TLR9 comparably contribute to DENV-induced immune activation. The significance of TLR9 in DENV-induced immune response is also confirmed in examination with the bone marrow-derived DCs prepared from Tlr9-knockout mice. Our study unravels a previously unrecognized phenomenon in which infection with an RNA virus, DENV, activates TLR9 signaling by inducing mtDNA release in human DCs.

Abstract
Objective: To analyze the characteristics of immunoglobulin heavy chain complementarity-determining region (IgH-CDR3) repertoire of peripheral B cells in a patient with primary biliary cholangitis (PBC) and to investigate the diversity of the immune system. Methods: Arm-PCR was used to amplify the IgH-CDR3 region of circulating B cells isolated from a PBC patient, and high-throughput sequencing was used to analyze the amplified product. The characteristics of immune repertoire were analyzed by bioinformatics. Results: In total, 329219 sequence reads were generated from the sample, with 325540 total CDR3 sequences and 72774 distinct CDR3 sequences, and the D50 of IGH-CDR3 was 7.7. The dominant CDR3 length of the sample was 45 nt (9.6%); the N addition with the highest frequency ranged from 13 to 14 nt (5.25%); the J trimming with the highest frequency was 0 nt (12.7%); the three most frequent V alleles were V4-59 (9.5%), V3-23 (8.1%), and V1-69 (6.4%). Conclusion: The diversity of IgH-CDR3 repertoire is relatively low in this patient with PBC, with several B-cell clonal expansions. The specificity needs to be further verified after increasing the sample size.

Abstract
Objective: To investigate the clinical and laboratory features of patients with liver disease and positive anti-liver/kidney microsomal-1 (anti-LKM-1) antibody, and to provide a reference for clinical diagnosis and differential diagnosis. Methods: The clinical data of patients with positive anti-LKM-1 antibody who were treated in our hospital from 2006 to 2016 were collected, and clinical and laboratory features were analyzed and compared. An analysis was also performed for special cases. Results: The measurement of related autoantibodies was performed for about 100 thousand case-times, and 15 patients were found to have positive anti-LKM-1 antibody. Among the 15 patients, 7 were diagnosed with type 2 autoimmune hepatitis (AIH) with an age of 11.0 ± 9.0 years and were all adolescents with acute onset; 8 were diagnosed with hepatitis C with an age of 51.5 ± 9.0 years, among whom 7 were middle-aged patients and 1 was a child aged 12 years, and all of them had an insidious onset. Compared with the patients with hepatitis C, the AIH patients had significantly higher levels of alanine aminotransferase (1 003.9 ± 904.3 U/L vs 57.0 ± 84.1 U/L, P < 0.05), aspartate aminotransferase (410.7 ± 660.3 U/L vs 34.9 ± 42.9 U/L, P < 0.05), and total bilirubin (98.0 ± 191.0 μmol/L vs 15.4 ± 6.0 μmol/L, P < 0.05). There was a reduction in immunoglobulin G after the treatment with immunosuppressant, compared with the baseline. Of all 8 patients with hepatitis C, 6 received antiviral therapy with interferon and ribavirin, and 5 out of them achieved complete response, among whom 4 had a reduction in the level of anti-LKM-1 antibody after treatment; however, a 12-year-old child developed liver failure after interferon treatment and died eventually. Conclusion: Positive anti-LKM-1 antibody is commonly seen in patients with type 2 AIH or hepatitis C, but there are differences between these two groups of patients in terms of age, disease onset, liver function, and the level of anti-LKM-1 antibody. The hepatitis C patients with a confirmed diagnosis and exclusion of autoimmune hepatitis can achieve good response to interferon under close monitoring, even if anti-LKM-1 antibody is positive. As for adolescent patients with hepatitis C and positive anti-LKM-1 antibody, the possibility of AIH should be excluded.

Abstract
OBJECTIVE To explore the application of the technique of terminal branches portal vein embolization(TBPVE)for planed hepatectomy. METHODS From February 2016 to June 2016, 4 patients with hepatocellular carcinoma underwent TBPVE and liver resection in Yuebei People's Hospital (n=3) and Jiangxi Ji'an Central People's Hospital (n=1). All of them were male and were 50, 64, 39 and 47 years old respectively. All the tumors located in the right lobe. All patients had the liver function of Child-Pugh A classification and liver cirrhosis level of G2S4. The standard liver volume (SLV) were 1 291, 1 109, 1 177 and 1 242 ml and estimated future liver remnant(FLR) were 315, 347, 306 and 323 ml respectively. The puncture site of TBPVE was determined by the three-dimensional reconstruction of portal vein. Three patients were punctured in the segment Ⅵ and the other one punctured in the segment Ⅲ. CT scan was repeated 2 weeks after TBPVE and FLR and FLR/SLV were calculated. All patients underwent right hepatectomy 2 weeks after TBPVE. RESULTS On the 14(th) day after TBPVE, the FLR of 4 patients were 529, 462, 469 and 498 ml which increased 67.9%, 33.1%, 53.3% and 54.2% compared with that before TBPVE, and FLR/SLV were 41.0%, 41.7%, 39.8% and 40.1% respectively. No severe complication occurred. Right hepatectomy were performed 2 weeks after TBPVE. No inflow blood control applied during the liver resection. The mean blood loss was 950 ml and the mean operating time was 3.3 hours (ranging from 3 to 4 hours). One patient had respiratory infection and two had slight jaundice and ascites for a short period. No other complication occurred. CONCLUSION The TBPVE could induce a rapid and large FLR volume that give chances to patients with small FLR to have liver resection for hepatocellular carcinoma.

Abstract
Objective: To research the regulation effects of Krüppel like zinc finger transcription factor 2 (KLF2) on γ-glutamylcysteine synthetase (γ-GCS) in airway epithelial cells of chronic obstructive pulmonary disease (COPD). Methods: (1) Human specimen experiment: lung tissue of pulmonary lobectomy patients with lung cancer with or without COPD was collected from Department of Thoracic Surgery of Hunan Cancer Hospital from December 2008 to December 2009. The patients were divided into COPD group and control group without COPD. The levels of KLF2, γ-GCS mRNA and protein expression in lung tissues were measured by immunohistochemistry and in situ hybridization (ISH). Then, the correlation between KLF2 and γ-GCS mRNA and protein expression levels were analyzed, as well as the correlation between KLF2 or γ-GCS protein and smoking index, percentage of forced expiratory volume in one second to predicted value (FEV1%), percentage of forced expiratory volume in one second to forced vital capacity (FVC/FEV1). (2) Animal experiment: the primary bronchial epithelial cells of rats were extracted by enzyme digestion. After 6 hours of incubation with 10% tobacco smoke extract (TSE), cellular glutathione (GSH) was measured by enzyme linked immunosorbent assay (ELISA) method. The cells were transfected by specific inhibitor of KLF2 through the liposom, which inhibited the protein expression of KLF2. Then, the cells were divided into KB group (blank control group without any treatment), KB+ TSE group (treated with TSE), NC group (control group transfected with miRNA), NC+ TSE group (treated with miRNA and TSE), 92a group (transfected with KLF2 inhibitor), 92a+ TSE group (treated with KLF2 inhibitor transfection and TSE) based in the treatment. After that, the changes of KLF2 and γ-GCS mRNA and protein expression in the cells of each group were measured by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot method. Results: (1) Human specimen experiment: The expressions of KLF2 mRNA, protein and γ-GCS mRNA, protein in the lung tissue of COPD patients were strong positive and higher than those in control group (0.32±0.04 vs 0.19±0.03, 0.35±0.05 vs 0.22±0.03; 0.28±0.03 vs 0.16±0.03, 0.31±0.05 vs 0.21±0.03; all P<0.01). Linear correlation analysis showed that KLF2 mRNA and protein were positively correlated with γ-GCS mRNA and protein (r=0.705, 0.722; both P<0.01). The KLF2 and γ-GCS protein were positively correlated with smoking index, FEV1% and FEV1/FVC (r=0.552, 0.728, 0.670, and r=0.631, 0.727, 0.657; all P<0.01). (2) Animal experiment: The level of GSH in KB+ TSE group was significantly higher than that in KB group[(28.05±2.04) vs (7.27±0.33) nmol/mg, P<0.01]. The KLF2 mRNA, protein and γ-GCS mRNA, protein in KB+ TSE group (1.715±0.026, 1.842±0.028 and 2.117±0.067, 1.879±0.065) were higher than those in KB group (1.130±0.017, 1.177±0.033 and 1.378±0.053, 1.177±0.042; all P<0.05), and those in 92a group (0.472±0.028, 0.634±0.025 and 0.582±0.025, 0.554±0.021) were significantly lower than those in KB group, NC group (1.047±0.056, 1.092±0.045 and 1.303±0.037, 1.252±0.037), and those in TSE+ 92a group (0.262±0.017, 0.288±0.017 and 0.337±0.022, 0.321±0.022) were significantly lower than those in KB+ TSE group, 92a group and NC+ TSE group (1.576±0.036, 1.646±0.066 and 1.948±0.093, 1.843±0.078) (all P<0.05). Conclusion: KLF2 exerts antioxidative effect by regulating the expression of γ-GCS in the bronchial epithelial cells of chronic obstructive pulmonary disease.

Abstract
The relationship between androgen deprivation therapy (ADT) and coronary heart disease (CHD) remains controversial. Furthermore, the majority of such studies focused on Caucasian populations, and there is still a paucity of studies among Asian populations. This population-based study aimed to investigate the relationship between ADT and CHD in an ethnic Chinese (i.e., Taiwanese) population. We used data sourced from the Taiwan 'Longitudinal Health Insurance Database'. This study included 1278 patients with prostate cancer in the study group and 1278 subjects without prostate cancer in the comparison group. Each patient was individually tracked for a 3-year period to identify those who had subsequently received a diagnosis of CHD. The results showed that the incidence rate of CHD during the 3-year follow-up period was 4.69 (95% CI: 2.99-5.48) per 100 person-years and 2.67 (95% CI: 2.15-3.27) per 100 person-years for the study and comparison cohort, respectively. The Cox proportional hazard regression showed that the hazard ratio for CHD during the 3-year follow-up period for prostate cancer patients was 1.65 (95% confidence interval (CI) = 1.25-2.16) compared with comparison subjects after adjusting for patients' geographic location, monthly income, urbanization level, hypertension, diabetes, hyperlipidemia, and stroke. However, we failed to find a significant difference in the adjusted hazard of CHD during the 3-year follow-up period between prostate cancer patients who did and those who did not receive ADT (hazard ratio = 1.12, 95% CI = 0.79-1.59). We concluded that prostate cancer but not ADT was significantly associated with CHD. In addition, a common cause of prostate cancer and coronary heart disease could exist.

Abstract
AIM Coronary artery disease is the main cause of mortality and morbidity in dialysis-dependent renal failure patients. Both the prevalence and incidence of renal failure are high in Taiwan. However, there were few reports exploring the outcome of coronary aortic bypass grafting (CABG) in these patients. The aim of this study was to determine the survival outcome and risk factors for mortality from CABG in this population. METHODS The operative, early postoperative and late results of 170 dialysis patients undergoing isolated coronary artery bypass grafting from January, 2000 to January, 2012 were retrospectively reviewed. Operative mortality, long-term survival, and risk factors were analyzed. RESULTS One hundred and seventeen patients (68.8%) were male, and the mean age was 61.5±10.3 years (range, 34-86 years). Follow-up was 40.3±32.1 months. Operative mortality was 8.2%. Actuarial survival, including operative mortality, was 81±3% at 1 year, 68±4% at 3 years, 58±5% at 5 years and 49±6% at 10 years, better than the natural course of dialysis-dependent renal failure patients. Age, emergent operation, postoperative ventricular tachycardia or fibrillation, postoperative intra-aortic balloon pump insertion, gastrointestinal bleeding, and left internal mammary artery graft were significant predictors of operative or long term mortality. Most causes of late death were due to infection or cardiac events. CONCLUSION CABG in dialysis patients is associated with a higher incidence of complications, but has acceptable mortality. CABG is beneficial in this population. Internal mammary artery grafting may provide more favorable long term outcomes.

Abstract
The stability and exchange interaction mechanism of a doped Zn12O12 cluster with Mn and C atoms were investigated by first-principles calculations. For the Mn-doped Zn12O12 cluster, it is identified that a superexchange interaction deriving the hybridization between the Mn 3d(2/x)-2/y and O 2p(xy) orbitals dominates the Mn(↑)-Mn(↓) antiferromagnetic coupling, although a direct exchange interaction deriving the Mn-Mn bonding is also found. In order to turn the Mn spin state in the Mn-doped Zn12O12 cluster, C doping is undertaken to change the magnetic interactions of these impurities. It is proved that the C incorporation into the Mn-doped Zn12O12 cluster destroys the short-ranged antiferromagnetic coupling, where multiple exchange interactions take over, including the direct exchange interaction and the kinetic p-d exchange interaction partially due to the geometric distortion and surface effect with dangling bonds (sp(2)-like hybrids). It is concluded that the kinetic p-d exchange interaction plays a dominant role in Mn/C-doped Zn12O12 clusters.

Abstract
The association between diabetes and benign prostatic hyperplasia remains inconclusive. In this case-control study, we examined the association of diabetes with benign prostatic enlargement (BPE) using the Longitudinal Health Insurance Database 2000 in Taiwan. In total, 20 152 patients with BPE as cases and 20 152 age-matched patients without BPE were included as controls. Conditional logistic regression analyses were performed to calculate the odds ratio (OR) and corresponding 95% CI for having been previously diagnosed with diabetes between cases and controls. We found that of the 40 304 sampled patients, 9492 (23.6%) had a history of diabetes before the index date. This mean age for the sampled patients was 65.9 with a standard deviation of 12.0 years. A Chi-squared test revealed that there was a significant difference in the prevalence of prior diabetes between cases and controls (25.3% vs. 21.8%, p < 0.001). The conditional logistic regression found that the OR of prior diabetes for cases was 1.21 (95% CI = 1.15-1.27) compared with controls. However, after adjusting for geographic region, monthly income, urbanization level, hypertension, coronary heart disease (CHD), hyperlipidemia, tobacco use disorder, and obesity, the association between prior diabetes and BPE did not reach a statistically significant level (OR = 1.03, 95% CI = 0.98-1.08). In addition, it was noteworthy that hypertension (OR = 1.25, 95% CI = 1.20-1.31), CHD (OR = 1.40, 95% CI = 1.32-1.48), and hyperlipidemia (OR = 1.30, 95% CI = 1.24-1.36) were all significantly associated with BPE. We found that men with a diagnosis of diabetes were not significantly associated with BPE after adjusting for patient's sociodemographic characteristics and comorbidities.

Abstract
INTRODUCTION Statin may induce epithelial dysfunction of the bladder urothelium. Epithelial dysfunction was proposed as one of the major potential etiologies for bladder pain syndrome/interstitial cystitis (BPS/IC). In this study, we examined the association between statin use and BPS/IC using a population-based study. SUBJECTS AND METHODS This case-control study used the Taiwan Longitudinal Health Insurance Database. In total, 815 female subjects with BPS/IC and 4075 randomly selected female controls were included. We used a conditional logistic regression to compute the odds ratio (OR) for having previously used statins between cases and controls. RESULTS A conditional logistic regression analysis showed that the OR of prior statin users for cases was 1.52 (95% confidence interval (CI): 1.19-1.94) compared to controls after adjusting for diabetes, hypertension, coronary heart disease, obesity, chronic pelvic pain, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, panic disorder, migraines, sicca syndrome, allergies, endometriosis, and asthma. Furthermore, adjusted ORs of regular and irregular statin use for cases were 1.58 (95% CI: 1.20-2.08) and 1.53 (95% CI: 1.02-2.31), respectively, compared to controls. CONCLUSION We concluded that there was an association between statin use and BPS/IC.

Abstract
Galectin-9 (Gal-9) exerts immunosuppressive effects by inducing apoptosis in T cells that produce interferon-γ and interleukin (IL)-17. However, Gal-9 can be pro-inflammatory in lipopolysaccharide-stimulated monocytes. Using microarray analysis, we observed that Gal-9 was up-regulated in human dendritic cells (DCs) after dengue virus (DV) infection. The investigation into the immunomodulatory effects and mechanisms of Gal-9 in DCs exposed to DV revealed that DV infection specifically increased mRNA and protein levels of Gal-9 but not those of Gal-1 or Gal-3. Blocking p38, but not c-Jun N-terminal kinase or extracellular signal-regulated kinase (ERK), inhibited DV-induced expression of Gal-9. Reduction in Gal-9 by small interference RNA treatment suppressed DV-stimulated migration of DCs towards the chemoattractants CCL19 and CCL21. In addition, DV-induced IL-12p40 production was reduced after knockdown of Gal-9 in DCs. Furthermore, Gal-9 deficiency suppressed DV-induced activation of nuclear factor-κB. Inhibition of DV-induced DC migration under conditions of Gal-9 deficiency was mediated through suppressing ERK activation but not by regulating the expression of CCR7, the receptor for CCL19 and CCL21. Both the reduction in IL-12 production and the suppression of ERK activity might account for the inhibition of DV-induced DC migration after knockdown of Gal-9. In summary, this study reveals the roles of Gal-9 in DV-induced migration of DCs. The findings indicate that Gal-9 might be a therapeutic target for preventing immunopathogenesis induced by DV infection.

Abstract
BACKGROUND AND PURPOSE Smooth muscle transient receptor potential melastatin 4 (TRPM4) channels play a fundamental role in the development of the myogenic arterial constriction that is necessary for blood flow autoregulation. As TRPM4 channels are present throughout the vasculature, we investigated their potential role in non-myogenic resistance arteries using the TRPM4 inhibitor 9-phenanthrol. EXPERIMENTAL APPROACH Pressure and wire myography were used to assess the reactivity of rat arteries, the latter in combination with measurements of smooth muscle membrane potential. Immunohistochemistry (IHC) and endothelial cell (EC) calcium changes were assessed in pressurized vessels and patch clamp measurements made in isolated ECs. KEY RESULTS The TRPM4 inhibitor 9-phenanthrol reversibly hyperpolarized mesenteric arteries to circa EK and blocked α1 -adrenoceptor-mediated vasoconstriction. Hyperpolarization was abolished and vasoconstriction re-established by damaging the endothelium. In mesenteric and cerebral artery smooth muscle, 9-phenanthrol hyperpolarization was effectively blocked by the KCa 3.1 inhibitor TRAM-34. 9-Phenanthrol did not increase mesenteric EC [Ca(2+)]i , and Na(+) substitution with N-methyl-D-glucamine only increased the muscle resting potential by 10 mV. Immunolabelling for TRPM4 was restricted to the endothelium and perivascular tissue. CONCLUSIONS AND IMPLICATIONS These data reveal a previously unrecognized action of the TRPM4 inhibitor 9-phenanthrol - the ability to act as an activator of EC KCa 3.1 channels. They do not indicate a functionally important role for TRPM4 channels in the reactivity of non-myogenic mesenteric arteries.

Abstract
BACKGROUND We compared intestinal, hepatic, and other organ function after hepatic portal occlusion with or without dexmedetomidine administration under general anaesthesia. METHODS In this prospective, randomized double-blind investigation, 44 patients undergoing elective hepatectomy with inflow occlusion were randomized into a dexmedetomidine group or a control group. The dexmedetomidine group received an initial dexmedetomidine loading dose of 1 μg kg(-1) over 10 min followed by a maintenance dose of 0.3 μg kg(-1) h(-1). In the control group, 0.9% sodium chloride was administered. The primary outcome was serum diamine oxidase (DAO) activity reflecting intestinal injury. The secondary outcomes included variables reflecting intestinal, hepatic, kidney, and cardiopulmonary function, and biomarkers of oxidative stress and systemic inflammatory response. RESULTS DAO activity was lower in the dexmedetomidine group than in the control group at 6 and 24 h after liver reperfusion [9.77 (1.07) vs14.29 (1.43) units ml(-1), P=0.021; 9.67 (0.98) vs 13.97 (1.31) units ml(-1), P=0.017]. d-lactate acid levels were lower during 1-72 h after liver reperfusion compared with the control group (all P<0.05). Also, the intestinal injury severity grade was decreased by dexmedetomidine (P=0.038). The biomarkers reflecting liver injury increased over time, but were lower in the dexmedetomidine group (all P<0.05), while the variables reflecting cardiopulmonary and renal function showed no differences between the groups (all P>0.05). CONCLUSIONS Dexmedetomidine administered perioperatively attenuates intestinal and hepatic injury in patients undergoing elective liver resection with inflow occlusion without any potential risk.

Abstract
AIM Limited realworld data existed for miniparasternotomy approach with good sample size in Asian cohorts and most previous studies were eclipsed by case heterogeneity. The goal of this study was to compare safety and quality outcomes of cardiac noncoronary valve operations by miniparasternotomy and full sternotomy approaches on riskadjusted basis. METHODS From our hospital database, we retrieved the cases of non-coronary valve operations from 1 January 2005 to 31 December 2012, including re-do, emergent, and combined procedures. Estimated EuroScore-II and propensity score for choosing mini-parasternotomy were adjusted for in the regression models on hospital mortality, complications (pneumonia, stroke, sepsis, etc.), and quality parameters (length of stay, ICU time, ventilator time, etc.). Non-complicated cases, defined as survival to discharge, ventilator use not over one week, and intensive care unit stay not over two weeks, were used for quality parameters. RESULTS There were 283 miniparasternotomy and 177 full sternotomy cases. EuroScore-II differed significantly (medians 2.1 vs. 4.7, p<0.001). Propensity scores for choosing miniparasternotomy were higher with lower EuroScore-II (OR=0.91 per 1%, p<0.001), aortic regurgitation (OR=2.3, p=0.005), and aortic non-mitral valve disease (OR=3.9, p<0.001). Adjusted for propensity score and EuroScore-II, mini-parasternotomy group had less pneumonia (OR=0.32, p=0.043), less sepsis (OR=0.31, p=0.045), and shorter non-complicated length of stay (coefficient=7.2 (day), p<0.001) than full sternotomy group, whereas Kaplan-Meier survival, non-complicated ICU time, non-complicated ventilator time, and 30-day mortality did not differ significantly. CONCLUSION The propensity-adjusted analysis demonstrated encouraging safety and quality outcomes for mini-parasternotomy valve operation in carefully selected patients.

Abstract
Osteoarthritis (OA) is a common joint disorder with varying degrees of inflammation. The ideal anti-OA drug should have immunomodulatory effects while at the same time having limited or no toxicity. We examined the anti-inflammatory effects of Ginkgo biloba extract (EGb) in interleukin-1 (IL-1)-stimulated human chondrocytes. Chondrocytes were prepared from cartilage specimens taken from patients with osteoarthritis who had received total hip or total knee replacement. The concentrations of chemokines and the degree of cell migration were determined by ELISA and chemotaxis assays, respectively. The activation of inducible nitric oxide synthase (iNOS), mitogen-activated protein kinases (MAPKs), activator protein-1 (AP-1), and nuclear factor-kappaB (NF-κB) was determined by immunoblotting, immunohistochemistry, and electrophoretic mobility shift assay. We found that EGb inhibited IL-1-induced production of chemokines, which in turn resulted in attenuation of THP-1 cell migration toward EGb-treated cell culture medium. EGb also suppressed IL-1-stimulated iNOS expression and release of nitric oxide (NO). The EGb-mediated suppression of the iNOS-NO pathway correlated with the attenuation of activator protein-1 (AP-1) but not nuclear factor-kappaB (NF-κB) DNA-binding activity. Of the mitogen-activated protein kinases (MAPKs), EGb inhibited only c-Jun N-terminal kinase (JNK). Unexpectedly, EGb selectively caused degradation of c-Jun protein. Further investigation revealed that EGb-mediated c-Jun degradation was preceded by ubiquitination of c-Jun and could be prevented by the proteosome inhibitor MG-132. The results imply that EGb protects against chondrocyte degeneration by inhibiting JNK activation and inducing ubiquitination-dependent c-Jun degradation. Although additional research is needed, our results suggest that EGb is a potential therapeutic agent for the treatment of OA.

Abstract
OBJECTIVE China is proceeding into the aging society. There are near 6 million elderly suffering senile dementia,while cognitive impairment is an important clinical feature in dementia. The factors involved in cognitive dysfunction in the middle-aged and the elderly persons were investigated. DESIGN Cross-sectional study. SETTING Community dwellers and nursing home residents in Tianjin, China. SUBJECTS Total of 662 subjects(284 men and 378 women) aged 55-93. METHODS A designed questionnaire was used to collect their demographic data, information of disease and medication, and life style. Mini-mental state examination (MMSE) and Basic Cognitive Aptitude Tests (BCAT) software were applied to evaluate their cognitive function. Serum total homocysteine (tHcy) level was quantified by enzyme conversion method. A multiple linear stepwise regression analysis was applied to find the influencing factors of cognitive function. RESULTS The average serum tHcy concentrations was 15.95±7.29 μmol/L, while the prevalence of hyperhomocysteinemia (HHE) was 45.4%. The average serum tHcy level and prevalence of HHE were higher in men than those in women after ruling out the age differences. The mean MMSE and BCAT scores were 26.74±2.71 and 50.26±18.84 respectively. The BCAT score was negatively correlated with age and positively correlated with education. Multiple linear stepwise regression equations showed that the P value was less than 0.001, the BCAT regression equation showed that the R2=0.453. Serum tHcy concentration was negatively correlated with total scores of BCAT, digit copy, Chinese character comparison, mental arithmetic, Chinese character rotation and recall answer of mental arithmetic test. Total scores of BCAT were negatively correlated with education, inhabitancy, serum tHcy concentration and age. In addition, Chinese character rotation was correlated with tea consumption. Remembrance and recognition of dual words and nonsense figures was correlated with income level. CONCLUSIONS Hyperhomocysteinemia is associated with cognitive impairment in the middle-aged and the elderly persons in Tianjin. The BCAT scores could well represent the detailed cognitive function in elderly and negatively correlate with age, but positively correlated with education level. Serum tHcy concentration was negatively correlated with total BCAT scores.

Abstract
AIMS The formation of foam cells is crucial in the initiation and progression of atherosclerosis. One of the critical steps in foam cell formation is the uptake of low-density lipoprotein (LDL) by macrophages via scavenger receptors (SRs). This study examined the role of protein kinase C (PKC) isoforms on foam cell formation. METHODS AND RESULTS The effects of short-hairpin RNA (shRNA) and small interfering RNA (siRNA) against classical PKC and novel PKC isoforms were investigated in THP-1-derived macrophages and primary macrophages. The knockdown of PKCδ inhibited oxidized LDL (OxLDL) uptake and intracellular cholesterol accumulation in both cell models. The reduction of PKCδ resulted in decreased expression of SR-A and CD36. Similar conclusions were obtained in examining the effects of a PKCδ inhibitor, rottlerin. Molecular investigation revealed that a decrease in PKCδ inhibited protein kinase B (PKB/Akt) expression and extracellular-signal-regulated kinase (ERK) phosphorylation. Surprisingly, PKCδ-knockdown selectively decreased protein but not the mRNA level of PKCβI and PKCβII. We showed that the inhibition of phosphatidylinositol 3-kinase (PI3K)/Akt upstream of ERK decreased SR-A and CD36 expression; however, the inhibition of ERK or PKCβ downstream of ERK attenuated SR-A but not CD36 expression. We further demonstrated that PKCδ could be induced by pro-atherogenic mediators, OxLDL and interferon-γ. Notably, PKCδ, phosphorylated ERK, Akt, and SR-A were highly expressed in human atherosclerotic arteries and CD68-positive macrophages as visualized by immunohistochemical staining. CONCLUSION Through regulating PI3K/Akt and ERK activity, PKCδ affects SR-A and CD36 expression and foam cell formation. The results suggest PKCδ as a potential target for atherosclerosis therapeutics.

Abstract
We have fabricated surface-enhanced Raman scattering (SERS) substrates based on arrays of silver nanoparticles grown on porous anodic alumina templates. Using this nanotechnology platform, label-free and high-speed detection of bacteria are achieved. SERS spectra of various bacteria including Staphylococcus Aureus (Gram-positive bacterium), Klebsiella Pneumoniae (Gram-negative bacterium), and Mycobacterium Smegmatis (Mycobacterium) were recorded. The highly reproducible SERS-based technological platform is capable of differentiating different kinds of bacteria by PCA, LDA, clustering analysis, and SVM methods, which provides promising opportunity for biosensing of clinical microbes.

Abstract
BACKGROUND Using tumor necrosis factor-alpha (TNF-α)-activated porcine chondrocytes as a screening tool, we aim to synthesize and identify small-molecule inhibitors preserving immunomodulatory effects as therapeutics for osteoarthritis (OA). METHODS Chondrocytes were isolated from pig joints. A minilibrary of 300 benzamide-linked small molecules was established. The levels of inducible nitric oxide synthase (iNOS) and nitric oxide (NO) were measured by Western blot and Griess reaction, respectively. Proteoglycan degradation in cartilage explants was determined by histochemistry analysis. The activation of transcription factors and protein kinases was determined by electrophoretic mobility shift assays or Western blots. Zymography and real-time reverse transcriptase-polymerase chain reaction were used to determine enzyme activity and expression of matrix metalloproteinases (MMPs) and aggrecanases, respectively. RESULTS Bioassay screening of benzamide-linked small molecules revealed that 2-hydroxy-N-[3-(trifluoromethyl)phenyl]benzamide (HS-Cf) was a potent inhibitor of NO production and iNOS expression in TNF-α-stimulated porcine chondrocytes. HS-Cf suppressed TNF-α-induced activity of MMP-13 and expressions of several aggrecanases and prevented TNF-α-mediated reduction of collagen II. Histochemistry analysis confirmed that HS-Cf could prevent TNF-α-induced degradation and release of proteoglycan/aggrecan in cartilage explants. Such effects by HS-Cf were likely through suppressing TNF-α-induced interferon regulatory factor-1 (IRF-1) but not nuclear factor-kappaB signaling. The significance of IRF-1 was further confirmed by short hairpin knockdown studies. CONCLUSIONS In a minilibrary containing 300 small molecules, we identified a benzamide-linked small molecule, HS-Cf, that through down-regulating TNF-α-induced IRF-1 activity suppressed chondrocyte activation and prevented cartilage destruction. HS-Cf might be a potential disease-modifying drug for OA therapeutics.

Abstract
OBJECTIVES The major risk factor for OA is ageing; however, the mechanisms remain largely unclear. We investigated the effects and mechanisms of advanced glycation end products (AGEs) that accumulate in aged joints in chondrocytes. METHODS Porcine chondrocytes or cartilage fragments were prepared. Gene expression of MMPs and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) was assessed by real-time RT-PCR. Gelatin zymography was used to determine MMP-13 enzyme activity. Histochemistry or immunoblotting analysis was applied to determine the expression of collagen II, proteoglycan and aggrecan. Electrophoretic mobility shift assay and immunoblotting were used to study the activation of signal transducer and activator of transcription 3 (STAT3). Genetic manipulations with short hairpin RNA (shRNA) or dominant negative constructs were applied. RESULTS AGE enhanced expression and enzyme activity of MMP and ADAMTS genes and resulted in reduction of collagen II. Both janus kinase 2 (JAK2) and JAK3 inhibitors suppressed AGE-induced MMP-13, ADAMTS-4 and ADAMTS-5 expression and enzyme activity. Inhibition of JAK2 or JAK3 prevented AGE-mediated decrease of collagen II in chondrocytes and proteoglycan (aggrecan) degradation in cartilage fragments. In addition, interference of STAT3 expression inhibited AGE-induced MMP-13 and ADAMTS enzyme activities and mRNA levels. Furthermore, expression of the dominant negative receptor of AGE (DN-RAGE) blocked AGE-induced STAT3 phosphorylation. CONCLUSION Blocking JAK/STAT3 signalling pathway inhibited AGE-induced activation of MMP-13 and ADAMTS and prevented AGE-mediated decrease of collagen II and proteoglycan (aggrecan). The results indicated that JAK/STAT3 pathway may be a potential target for designing disease-modifying drugs for the treatment of OA.

Abstract
BACKGROUND AND PURPOSE 2-Methoxystypandrone (2-MS) is a naphthoquinone isolated from Polygonum cuspidatum, a Chinese herb used to treat bone diseases. Here we have determined whether 2-MS antagonised osteoclast development and bone resorption. EXPERIMENTAL APPROACH RAW264.7 cells were treated with receptor activator of nuclear factor kappaB (NF-kappaB) ligand (RANKL) to induce differentiation into osteoclasts. RT-PCR and Western blot were used to analyse osteoclast-associated gene expression and signalling pathways. KEY RESULTS The number of multinuclear osteoclasts, actin rings and resorption pit formation were markedly inhibited by 2-MS, targeting osteoclast differentiation at an early stage and without significant cytotoxicity. The anti-resorption effect of 2-MS was accompanied by decreasing dendritic cell-specific transmembrane protein and matrix metalloproteinase-9 (MMP-9) mRNA expression. RANKL-increased MMP-9 gelatinolytic activity was also attenuated by concurrent, but not by subsequent addition of 2-MS. 2-MS markedly inhibited not only the RANKL-triggered nuclear translocations of NF-kappaB, c-Fos and nuclear factor of activated T cells c1 (NFATc1), but also the subsequent NFATc1 induction. Degradation of IkappaB and phosphorylation of mitogen-activated protein kinases were also suppressed. RANKL facilitated the formation of signaling complexes of tumour necrosis factor receptor-associated factor 6 and transforming growth factor beta-activated kinase 1 (TRAF6-TAK1), important for osteoclastogenesis and formation of such signalling complexes was prevented by 2-MS. CONCLUSIONS AND IMPLICATIONS The anti-osteoclastogenic effects of 2-MS could reflect the block of RANKL-induced association of TRAF6-TAK1 complexes with consequent decrease of IkappaB-mediated NF-kappaB and mitogen-activated protein kinases-mediated c-Fos activation pathways and suppression of NFATc1 and other gene expression, essential for bone resorption.

Abstract
Introduction Accumulation of advanced glycation end products (AGEs) in joints contributes to the pathogenesis of cartilage damage in osteoarthritis (OA). We aim to explore the potential chondroprotective effects of resveratrol on AGEs-stimulated porcine chondrocytes and cartilage explants. Methods Chondrocytes were isolated from pig joints. Activation of the IκB kinase (IKK)-IκBα-nuclear factor-kappaB (NF-κB) and c-Jun N-terminal kinase (JNK)/extracellular signal-regulated kinase (ERK)-activator protein-1 (AP-1) pathways was assessed by electrophoretic mobility shift assay (EMSA), Western blot and transfection assay. The levels of inducible nitric oxide synthase (iNOS)-NO and cyclooxygenase-2 (COX-2)-prostaglandin E2 (PGE2) were measured by Western blot, Griess reaction or ELISA. The expression and enzyme activity of matrix metalloproteinase-13 (MMP-13) were determined by real time RT/PCR and gelatin zymography, respectively. Results We show that AGEs-induced expression of iNOS and COX-2 and production of NO and PGE2 were suppressed by resveratrol. Such effects of resveratrol were likely mediated through inhibiting IKK-IκBα-NF-κB and JNK/ERK-AP-1 signaling pathways induced by AGEs. By targeting these critical signaling pathways, resveratrol decreased AGEs-stimulated expression and activity of MMP-13 and prevented AGEs-mediated destruction of collagen II. Histochemistry analysis further confirms that resveratrol could prevent AGEs-induced degradation of proteoglycan and aggrecan in cartilage explants. Conclusions The present study reveals not only the effects and mechanisms regarding how resveratrol may protect cartilage from AGEs-mediated damage but also the potential therapeutic benefit of resveratrol in the treatment of OA.

Abstract
OBJECTIVES To investigate whether the National Institutes of Health Stroke Scale (NIHSS) can be used to predict mortality and functional outcome in patients presenting with intracerebral haemorrhage. DESIGN Retrospective study of a prospectively collected cohort. SETTING Regional hospital, Hong Kong. PATIENTS A cohort of 359 patients presented to our hospital from 1996 to 2001 with their first-ever stroke and intracerebral haemorrhage. MAIN OUTCOME MEASURES The sensitivity and specificity of the NIHSS with a cut-off point of 20 in predicting mortality at 30 days and 5 years, and a favourable functional outcome at 5 years. RESULTS A total of 359 patients were available for analysis and were divided into three subgroups according to the site and the size of the haematoma. The NIHSS can predict 30-day mortality with a sensitivity of 81% [corrected] and a specificity of 90% [corrected] The NIHSS can predict 5-year mortality with a sensitivity of 57% [corrected] and a specificity of 92% [corrected] In predicting favourable functional outcomes at 5 years, the NIHSS had a sensitivity of 98% [corrected] and a specificity of 16% [corrected] CONCLUSIONS The NIHSS performed on admission can be used to predict mortality at 30 days and 5 years as well as favourable functional outcome at 5 years, all with an acceptable sensitivity and specificity.

Abstract
Silymarin, a standardized extract of the milk thistle (Silybum marianum), has a long tradition as a herbal remedy, and was introduced as a hepatoprotective agent a few years ago. However, the therapeutic effects of silymarin remain undefined. Carbon tetrachloride (CCl4) is a xenobiotic used extensively to induce oxidative stress and is one of the most widely used hepatic toxins for experimental induction of liver fibrosis in the laboratory. In this study, we investigated the restoration of the CCl4-induced hepatic fibrosis by high dose of silymarin in rats. After treatment with oil (as normal group; n = 6) or CCl4 [as model (n = 7) and therapeutic (n = 7) groups] by intragastric delivery for 8 weeks for the induction of liver fibrosis, the rats in the normal and model group were administered orally normal saline four times a week for 3 weeks whilst the therapeutic group received silymarin (200 mg/kg). The histopathological changes were observed with Masson staining. The results showed that the restoration of the CCl4-induced damage of liver fibrosis in the therapeutic group was significantly increased as compared to that in the model group. Moreover, silymarin significantly decreased the elevation of aspartate aminotransferase (AST), alanine aminotransferase, and alkaline phosphatase in serum, and also reversed the altered expressions of alpha-smooth muscle actin in liver tissue. Therefore, these findings indicated that silymarin may have the potential to increase the resolution of the CCl4-induced liver fibrosis in rats.
