Abstract
AIMS Isoniazid (INH) has been used as a first-line drug to treat tuberculosis (TB) for more than 50 years. However, large interindividual variability was found in its pharmacokinetics, and effects of nonadherence to INH treatment and corresponding remedy regime remain unclear. This study aimed to develop a population pharmacokinetic (PPK) model of INH in Chinese patients with TB to provide model-informed precision dosing and explore appropriate remedial dosing regimens for nonadherent patients. METHODS In total, 1012 INH observations from 736 TB patients were included. A nonlinear mixed-effects modelling was used to analyse the PPK of INH. Using Monte Carlo simulations to determine optimal dosage regimens and design remedial dosing regimens. RESULTS A 2-compartmental model, including first-order absorption and elimination with allometric scaling, was found to best describe the PK characteristics of INH. A mixture model was used to characterize dual rates of INH elimination. Estimates of apparent clearance in fast and slow eliminators were 28.0 and 11.2 L/h, respectively. The proportion of fast eliminators in the population was estimated to be 40.5%. Monte Carlo simulations determined optimal dosage regimens for slow and fast eliminators with different body weight. For remedial dosing regimens, the missed dose should be taken as soon as possible when the delay does not exceed 12 h, and an additional dose is not needed. delay for an INH dose exceeds 12 h, the patient only needs to take the next single dose normally. CONCLUSION PPK modelling and simulation provide valid evidence on the precision dosing and remedial dosing regimen of INH.

Abstract
In the present study, we focused on whether the analgesic effect of Electroacupuncture (EA) is related to the regulation of oxidative stress. We established a chronic inflammatory pain model in male rats by a single injection of complete Freund's adjuvant (CFA) and then treated the animals with daily EA stimulation at the site of "zusanli". The analgesic effect of EA was evaluated by measuring the paw withdrawal threshold (PWT) when rats received mechanical and thermal pain stimulation. The levels of inflammation-related molecules and oxidative stress-related markers in the spinal cord were measured by western blotting or ELISA kits. EA stimulation and antioxidants effectively increased the PWT in CFA rats. Co-treatment of CFA rats with the ROS donor t-butyl hydroperoxide (t-BOOH) further decreased the PWT and weakened the analgesic effect of EA. EA treatment inhibited inflammation and oxidative stress, as shown by decreased levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), IL-6, and MDA and increased activity of SOD and catalase. Moreover, EA reduced the expression of p-p38, p-ERK, and p-p65 and simultaneously downregulated the expression of TRPV1 and TRPV4 in CFA rats. In an in vitro study, direct stimulation with t-BOOH to the C6 cells increased the production of TNF-alpha, IL-1beta, IL-6, activated p38, ERK, and p65 and up-regulated the expression of TRPV1 and TRPV4, and these effects could be prevented by the ROS scavenger PBN. Taken together, our data indicate that the inhibition of oxidative stress and the generation of ROS contribute to the analgesic effect of EA in male CFA rats.

Abstract
Standard management protocols are lacking and specific antidotes are unavailable for acute carbamazepine (CBZ) poisoning. The objective of this review is to provide currently available information on acute CBZ poisoning, including its management, by describing and summarizing various therapeutic methods for its treatment according to previously published studies. Several treatment methods for CBZ poisoning will be briefly introduced, their advantages and disadvantages will be analyzed and compared, and suggestions for the clinical treatment of CBZ poisoning will be provided. A literature search was performed in various English and Chinese databases. In addition, the reference lists of identified articles were screened for additional relevant studies, including non-indexed reports. Non-peer-reviewed sources were also included. In the present review, 154 articles met the inclusion criteria including case reports, case series, descriptive cohorts, pharmacokinetic studies, and in vitro studies. Data on 67 patients, including 4 fatalities, were reviewed. Based on the summary of cases reported in the included articles, the cure rate of CBZ poisoning after symptomatic treatment was 82% and the efficiency of hemoperfusion was 58.2%. Based on the literature review, CBZ is moderately dialyzable and the recommendation for CBZ poisoning is supportive management and gastric lavage. In severe cases, extracorporeal treatment is recommended, with hemodialysis as the first choice.

Abstract
Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease whose pathogenesis mainly involves airway remodelling and alveolar destruction caused by inflammation, protease-antiprotease imbalance, oxidative stress, and imbalance between apoptosis and compensatory repair of lung tissue structure cells. In recent years, the role of the autoimmune response in COPD has attracted widespread attention, but there is still some controversy. This article reviewed the role of autoimmunity in COPD from different perspectives, starting with the relationship between autoimmunity and the pathogenesis of COPD.

Abstract
Radiotherapy is an effective therapy in tumour treatment. However, the characteristics of the tumour microenvironment, including hypoxia, low pH, and interstitial fluid pressure bring about radioresistance. To improve the anti-tumour effect of radiotherapy, it has been demonstrated that antiangiogenic therapy can be employed to repair the structural and functional defects of tumour angiogenic vessels, thereby preventing radioresistance or poor therapeutic drug delivery. In this study, we prepared triptolide (TP)-loaded Asn-Gly-Arg (NGR) peptide conjugated mPEG2000-DSPE-targeted liposomes (NGR-PEG-TP-LPs) to induce tumour blood vessel normalisation, to the end of increasing the sensitivity of tumour cells to radiotherapy. Further, to quantify the tumour vessel normalisation window, the structure and functionality of tumour blood vessels post NGR-PEG-TP-LPs treatment were evaluated. Thereafter, the anti-tumour effect of radiotherapy following these treatments was evaluated using HCT116 xenograft-bearing mouse models based on the tumour vessel normalisation period window. The results obtained showed that NGR-PEG-TP-LPs could modulate tumour vascular normalisation to increase the oxygen content of the tumour microenvironment and enhance the efficacy of radiotherapy. Further, liver and kidney toxicity tests indicated that NGR-PEG-TP-LPs are safe for application in cancer treatment.

Abstract
Presbyopia refers to the decline in the accommodation of eye that occurs with age, symptoms begin to appear after the age of 40 and the clarity of vision at near is insufficient to satisfy an individual's requirements. The correction of presbyopia include restoring natural accommodation and improving symptom. The former is still difficult to achieve at present, while the latter mainly involves wearing convex lens, and with more and more patients wanting to get rid of frame glasses, refractive surgery is gradually promoted and applied. Corneal refractive surgery, especially laser-assisted in situ keratomileusis, is one of the most common methods for surgical correction of presbyopia. We reviewed the recent literature to introduce the mechanism of corneal refractive surgery treating presbyopia and the efficacy of different surgical algorithms.

Abstract
Abstract
Background
Acute myocardial infarction (AMI) is associated with short-term and long-term mortality. Survivors of AMI suffer from cardiovascular events, among which heart failure (HF) is the most important factor affecting the prognosis. Echocardiography is a traditional method of measuring cardiac function, but it is inconvenient. Previous studies have identified the effectiveness of a new wearable coin-sized phonocardiogram (PCG) and electrocardiogram (ECG) device in HF patients. In our study, we apply this device in the hospitalization monitoring of post-AMI patients.
Purpose
The purpose of this study was to evaluate the role of the synchronized analysis of PCG and ECG in identifying cardiac functions in hospitalized AMI patients and to forecast adverse events for 30-days post-AMI in general clinical practice.
Methods
One hundred and sixty-three ST-elevated myocardial infarction (STEMI) patients and sixty-nine non-ST-elevated myocardial infarction (NSTEMI) patients were enrolled. All were admitted to the hospital and diagnosed with AMI. The left ventricular ejection function (LVEF) was determined by echocardiography and synchronized PCG and ECG signals were recorded using the wearable coin-sized PCG and ECG device on the first day of admission. PCG and ECG signals were analyzed to determine electromechanical activation time (EMAT), EMAT/RR (EMAT%), pre-ejection period/RR (PEP%), left ventricular systolic time/RR (LVST%), left ventricular ejection time/RR (LVET%). Primary endpoint was defined as the occurrence of major adverse cardiovascular events (MACE) following AMI in thirty days.
Results
ROC analysis demonstrated that the sensitivity and specificity of EMAT% >12.1% for the diagnosis of LVEF <50% were 81% and 82%, respectively. Overall, 232 patients were enrolled who were divided into four groups according to the classification of AMI and EMAT%. Patients in STEMI group with EMAT% >12.1% had a lower LVEF% (p<0.001), greater EMAT (p<0.001), PEP% (p<0.001), LVET% (p<0.001), LVST% (p=0.001), LVEDV (p<0.001) and LVESV (p<0.001). The same pattern was observed in NSTEMI patients between EMAT% >12.1% and EMAT≤12.1% group. Twenty-eight STEMI patients (17.28%) and seventeen NSTEMI patients (24.6%) developed a MACE event. Compared with EMAT≤12.1% group, EMAT% >12.1% group showed a higher occurrence of MACE, especially in post-STEMI patients (36.54% vs 8.11%, p<0.001).
Conclusion
PCG and ECG offer the possibility to assess the systolic parameters associated with left ventricular (LV) function and clinical status that differ between normal and heart failure states in acute AMI patients, with EMAT% >12.1% as a cut-off for deceased LV systolic function. Moreover, EMAT% >12.1% showed strong association with clinical outcome, suggesting EMAT% may be helpful to further improve the risk stratification of post-AMI patients, especially STEMI patients.

Abstract
BACKGROUND Latamoxef shows excellent antibacterial activity against anaerobic bacteria such as Bacteroides fragilis. Reports of thrombocytopenic toxicity of latamoxef are limited. This report presents a case of severe thrombocytopenia possibly induced by latamoxef, an infrequent adverse drug reaction in a young patient with tuberculosis and Crohn's disease in China.
CASE SUMMARY We reported a case of severe thrombocytopenia induced by latamoxef in a 28-year-old man with tuberculosis and Crohn's disease. On admission, the patient presented with a cough productive of bloody sputum, a chest computed tomogram suggested scattered mottled, high-density shadows in both lungs. Laboratory tests indicated a platelet count of 140000/μL. Considered a pulmonary bacterial infection, the patient received anti-infection therapy with latamoxef (dose: 2.0 g) intravenously Q12h. On the 9th day of treatment, the platelet count decreased to 44000/μL. On the 12th day, scattered purpura and ecchymosis appeared on the patient’s limbs and trunk, and the platelet count decreased to 9000/μL after latamoxef treatment for 15 d. Three days after discontinuation of latamoxef, the platelet count recovered to 157000/μL, and the area of scattered purpura and ecchymosis on the limbs and trunk decreased. The platelet counts remained in the normal range, and no thrombocytopenia was found at follow-up 15 mo after discharge.
CONCLUSION For patients treated with latamoxef, platelet counts should be carefully followed, and caregivers should be vigilant for the appearance of scattered ecchymosis.

Abstract
Pulmonary hypertension is a pathophysiological disorder with elevated pulmonary artery pressures that may involve multiple clinical conditions, yet the mechanism of pulmonary hypertension remains unclear. Metabolic reprogramming of structural cells (smooth muscle cells, endothelial cells, fibroblasts etc.) and immune cells (macrophages etc.) is a hallmark of pulmonary hypertension and leads to pulmonary vascular remodeling. Many studies have investigated the metabolic reprogramming in pulmonary hypertension and some potential therapeutic targets have been developed. In this review, recent work on metabolic programming in pulmonary hypertension is summarized.

Abstract
Abstract
Background
Coronary plaque progression is a major risk factor of adverse cardiac events in patients with coronary heart disease (CHD). Emerging evidence showed that attenuated high-density lipoprotein (HDL) function measured by cholesterol efflux capacity (CEC) was associated with development of atherosclerosis independent of HDL cholesterol level. In this study, we sought to investigate whether CEC is a predictor for coronary plaque progression in CHD patients.
Methods
We consecutively enrolled CHD patients from January 2017 to August 2019 in our Hospital who underwent elective percutaneous coronary intervention and had at least one non-target coronary lesion. Follow-up coronary angiography were performed at around 12 months. Fluorescence-labeled cholesterol and J774 macrophages were used to measure the CEC of ApoB-depleted serum sample from all patients. Quantitative coronary angiography (QCA) was performed both at baseline and follow-up to analyze the plaque progression.
Results
A total of 430 CHD patients with 586 non-target coronary lesions were included in the final analysis. During a mean follow-up time of 381.04±59.52 days, patients with decreased CEC presented more severe plaque progression (net luminal loss in highest to lowest CEC quartile: 0.22±0.42mm vs 0.20±0.41mm vs 0.13±0.36mm vs 0.11±0.34mm, p=0.035). In multivariate analysis, baseline CEC was independently associated with coronary plaque progression after adjustment for traditional risk factors including HDL cholesterol and ApoA-I, no matter treated as categorical variable (OR: 0.382 [95% CI 0.180–0.781] for highest to lowest quartile) or continuous variable (OR: 0.522 [95% CI 0.373–0.714] for per SD increase]. Furthermore, CEC demonstrated a better power in predicting coronary plaque progression compared with HDL cholesterol concentration (AUC=0.644 vs 0.514).
Conclusions
This study suggests that HDL function reflected by serum CEC is an independent predictor for coronary plaque progression in CHD patients.

Abstract
Objective: To explore the value of the concentration of adenosine triphosphate (ATP) in CD4(+)T lymphocytes in predicting repeated respiratory tract infections (RRTI) in silicosis patients. Methods: In April 2020, 614 silicosis patients admitted from March 2016 to March 2018 were included in the study, and they were divided into the RRTI group (n=105) and the non RRTI group (n=509) according to whether the occurrence of RRTI, another 30 healthy cases taken from body check were served as control group, and the concentrations of ATP produced by CD4(+)T lymphocytes was measured by ImmuKnow assay, and were compared between the three groups. And drawed the receiver operating characteristic (ROC) curve, and the Logistic regression analysis was used to explore the risk factors of RRTI. Results: The incidence of RRTI in silicosis patients was 17.10% (105/614) . The concentration of ATP produced by CD4(+)T lymphocytes in the RRTI group [ (260.42±90.36) mg/L] was significantly lower than that in the non RRTI group [ (413.66±138.74) mg/L] (t=-10.849, P<0.01) . The area under the ROC curve was 0.834, the cutoff value was 284 mg/L, the sensitivity was 0.88, and the specificity was 0.83. Logistic regression analysis showed that the concentration of ATP produced by CD4(+)T lymphocytes≤284 mg/L, impaired pulmonary ventilation function, serum albumin<40 g/L and diabetes were the risk factors of RRTI in silicosis patients (OR=2.126, 1.217, 1.164, 1.125, P<0.05) . Conclusion: Low CD4(+)T lymphocyte ATP value was a risk factor of RRTI in silicosis patients, and can predict the risk of RRTI in patients with silicosis.

Abstract
The poor penetration of nanoparticles in solid tumors has been a critical factor limiting the clinical benefits of nanomedicine. Therefore, we depleted the dense extracellular matrix (ECM) and normalized tumor vessels to enhance drug delivery and therapeutic efficacy. We used candesartan as an angiotensin system inhibitor, which reduced ECM content and facilitated "vascular normalization" by targeting the angiotensin-signaling axis, resulting in improved anti-cancer therapeutic effects. We also combined candesartan with PEGylated liposome-encapsulated zoledronic acid (ZOL) (PEG-ZOL-LPs) to assess how this affected anti-tumor therapy. Our findings indicated that the migration of 4T1 mouse breast cancer cells was inhibited by candesartan. Moreover, the ECM depletion (including collagen I and hyaluronan) by candesartan was achieved through the downregulation of TGF-β1 in vitro, consistent with in vivo results. Furthermore, treatment groups that received candesartan also had significantly decreased tumor vessel permeability and proportions of circulating endothelial progenitor cells (CEPCs) in the serum, which resulted in normalization of tumor vasculature and improved delivery of PEG-ZOL-LPs. Finally, the positive effect candesartan in terms of tumor growth was found not to have an impact of the efficacy of the PEG-ZOL-LPs treatment. This unexpected lack of effect of candesartan on the performance of PEG-ZOL-LPs would be due to dynamics of the effect of both treatments. It might be possible that a different protocol of administration could lead to a synergistic effect. Graphical abstract The schematic illustration showed that candesartan favored depletion of tumor stroma and tumor vascular normalization to improve the anti-cancer efficacy of PEG-ZOL-LPs.

Abstract
Abstract
Background
Catheter ablation is an important adjunct to device implantation for secondary prevention of ventricular tachycardia (VT). However, several factors may influence the success of ablations in terms of long-term freedom from VT recurrence. A thus far little examined factor is the use of general anaesthetic (GA) versus conscious sedation during the procedure, which has been shown to improve outcomes in persistent atrial fibrillation (AF) ablation.
Methods
Patients with structural heart disease VT undergoing ablations from January 2015 to March 2019 were retrospectively followed up at a single centre. End points were recurrent VT or device therapy (shock or anti-tachycardia pacing) at one year. Hazard ratios (HR) were generated using a multivariate Cox-regression proportional hazards model including variables of age at ablation, sex, amiodarone use at time of ablation, scar age, left ventricular ejection fraction, use of GA, and diagnosis of: diabetes mellitus (DM), hypertension (HTN), renal impairment or AF.
Results
79 patients (74 male, mean age 68.2+/- 10.3 years) were included. A substrate-based strategy of late potential ablation was employed. 69 had ischaemic and 10 had non-ischaemic cardiomyopathy. Mean scar age was 13.8 +/- 9.8 years; EF was 40-50% in 27 patients, 30-40% in 26 and < 30% in 26. 37 patients had implantable cardioverter defibrillators and 30 had cardiac resynchronisation therapy (CRT) defibrillator devices, 1 had a CRT- pacemaker device and 4 had dual chamber pacemakers. Comorbidities were: DM (16), HTN (31), renal impairment (13), AF (31). 62 patients (79.5%) were on amiodarone at the time of ablation. Mean procedure duration was 234.8 +/- 44.5 min and mean radiofrequency energy application time was 2247 +/- 862 s. 61 were first procedures and 18 were repeat procedures. One patient suffered a complication of groin haematoma. 62 patients (78.5%) underwent VT ablation under GA and 17 (21.5%) under sedation of midazolam and fentanyl. Patient characteristics did not differ between groups. Significant factors which increased freedom from VT recurrence or device therapy were HTN (88.9% vs 59.4%, HR 0.72, 95% confidence interval (CI): 0.007-0.75, p= 0.028), amiodarone treatment (50.0% vs 76.3%, HR 0.036, 95% CI: 0.003-0.404, p = 0.036) and ablation under GA rather than sedation (50.0% vs 75.0%, HR 0.055, 95% CI: 0.006-0.495, p = 0.01) (Fig 1).
Conclusions
In patients with structural heart disease undergoing VT ablation, outcomes are improved with the use of GA over conscious sedation.

Abstract
Mendelian randomization (MR) approach follows the Mendel's law of inheritance, which is called "Parental alleles randomly assigned to the offspring", and refers to use genetic variants as an instrumental variable to develop causal inference between the exposure factor and the outcome from observational study. In recent years, with the rapid development of genome-wide association study (GWAS) and various omics data,the disclosure of a large number of aggregated data provides an opportunity for the wide application of MR approach in causal inference. We introduce three methods widely used in MR and then apply them to explore causal relationship between blood metabolites and depressive. The advantages and disadvantages of three methods in causal inference are compared in order to provide reference for the application of MR in observational studies.

Abstract
Objective: This project aimed to explore the effectiveness of estimating individual treatment effect on real data, among the heterogeneous population, with Causal Forests (CF) method, to find out the characteristics of heterogeneous population. Methods: We designed and conducted four computer simulation schemes to verify the effect of estimating on individual treatment, using the CF under four different environments of the treatment effects. Real data was then analyzed for the catheterization on right heart. Results: Results from the simulation process showed that the values on individual treatment effect that were estimated by causal forests were consistent with the population effect as well as in line with the expected distribution under the setting of four different effect values. Results of real data analysis showed that values of individual treatment effect among most patients appeared positive, so the use of RHC could cause an increase of the '180-day mortality rate' in the sampled population. Patients with lower predicted probability of 2-mo survival and albumin were more likely to have a lower risk of death after using the RHC. Conclusion: CF method could be effectively used to estimate the individual treatment effect and helping the individuals to make decision on the receipt of treatment.

Abstract
Objective: To explore the gender-specific risk factors of new-onset cerebral hemorrhage. Methods: In this prospective cohort study,a total of 98 961 participants((51.1±12.6)years old), who underwent the 2006 to 2007 physical examination and met the inclusion criteria, were enrolled from the Kailuanstudy cohort. There were 78 908 (79.7%) male,and 20 053 (20.3%) female.The incidence of cerebral hemorrhage was observed once per year until December 31, 2016.The difference on the incidence of cerebral hemorrhage between male and female was compared. Multivariate Cox regression analysis was applied to analyze therisk factors of cerebral hemorrhage events among different genders. Results: The participants were followed up for(10.00±0.73) years,and 860 cerebral hemorrhage events were recorded during follow up. The incidence of cerebral hemorrhage in the population was 86.90/10 million person years (standardized incidence rate of 47.85/10 million person years). The incidence of cerebral hemorrhage was significantly higher in male (49.61/10 million person years) than in female (34.07/10 million person years, P<0.05). Multivariate Cox regression analysis showed that 45-59 years old, ≥ 60 years old, diabetes,and waist-hip ratio were more strongly related to new-onset of cerebral hemorrhage events in female than in male, and the hazard ratios(95%CI) were 2.33 (1.23-4.43) ,2.71 (1.30-5.66) ,2.16 (1.24-3.74) and 8.79 (1.42-54.32) in female versus 1.55 (1.21-1.97) ,2.16 (1.68-2.78) ,1.19 (0.93-1.53) and 3.21 (1.09-9.41) in male, respectively. The risk of male cerebral hemorrhage increased by 29% (HR=1.29, 95%CI 1.19-1.40) in male and 24% (HR=1.24, 95%CI 1.20-1.28) in female,when the systolic blood pressure increased 10 mmHg (1 mmHg=0.133 kPa). Conclusions: The incidence of cerebral hemorrhage is higher in male than in female in this cohort.The association between systolic blood pressure and cerebral hemorrhage is stronger in male than that in female.The associations between age, waist-hip ratio, diabetes and cerebral hemorrhage are stronger in female than in male.

Abstract
Objective: To investigate the clinicopathologic and molecular features of the rare cribriform morular variant of papillary thyroid carcinoma (CMV-PTC). Methods: The clinicopathologic data of 10 patients with CMV-PTC were retrospectively reviewed. Immunohistochemical (IHC) staining was done using LSAB method. DNA sequencing for APC were applied using Sanger method. BRAF V600E mutation was examined using ARMS method. The cytological, morphological, IHC and molecular features were analyzed. Results: All patients were female at an average age of 27 years old. The tumors were mostly located in the right lobe of thyroid. Fine needle aspiration cytology was performed in three patients; two were diagnosed as suspicious for PTC and one as PTC. Nine tumors presented as solitary nodule and two as multiple nodules in both lobes. Infiltration was demonstrated in three cases. The average size was 2.6 cm. The neoplastic cells were arranged in papillary, cribriform, solid and glandular patterns, with rare or without colloid inside the lumen. The number of morula varied, ranging from zero to many. The neoplastic cells were variably enlarged, showing round, oval or spindle shape. Nuclear irregularity was identified as irregular membrane, nuclear grooves or pseudoinclusion, but no typical ground glass feature. Peculiar nuclear clearing could be observed in the morular cells. IHC staining showed the neoplastic cells were negative for thyroglobulin and p63, but positive for TTF1, cytokeratin 19 and estrogen receptor. Diffuse staining with cytokeratin was seen in the neoplastic cells and the morula. Specific cytoplasmic and nuclear staining of β-catenin was seen in the neoplastic cells but not the morula. Ki-67 proliferation index was 1%-30%. No recurrence or metastasis was observed. One patient was demonstrated to harbor both somatic and germline mutations of the APC gene, who was found to have adenomatous polyposis and her mother died of colonic carcinoma. No BRAF V600E mutation was detected. Conclusions: CMV-PTC is rare and shows atypical cytological and clinicopathological features, and it is easily misdiagnosed.TG, TTF1, ER and β-catenin are specific IHC markers for CMV-PTC. The morula is negative for cytokeratin 19, in contrast to squamous metaplasia. Although CMV-PTC has indolent clinical behavior, a definite diagnosis is necessary to rule out the possibility of APC gene mutation and related extra-thyroidal neoplasm, such as FAP and Gardner syndrome.

Abstract
Objective: To investigate the effect and related mechanism of salvianolate on myocardial ischemia-reperfusion (I/R) injury in rats. Methods: Thirty-six adult Sprague-Dawley rats were divided into three groups (n=12 each) using random number table method: control group (coronary artery was not ligated) , I/R group (myocardial I/R model was established by ligation and opening of left anterior descending coronary artery) , and salvianolate+I/R group (5 mg/kg of salvianolate was injected through the tail vein at the time of reperfusion) .Triphenyltetrazolium chloride (TTC) stain was utilized to measure the myocardial infarct size. The ELISA method was used to detect myocardial necrotic markers, including cardiac troponin T (TnT) , creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) . Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining was used to analyses the levels of apoptosis. The levels of cleaved Caspase-3 protein were analyzed with Western blot.Cold luminescence method was used to detect the ATP level of myocardial tissue. The levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in myocardial tissue were detected by immunofluorescence. Results: (1) The infarct size in control group, I/R group and salvianolate+I/R group were 0, (23.90±5.66) %, and (12.06±5.97) %, respectively (P<0.01 or 0.05) . (2) The TnT level was (0.04±0.03) , (16.96±2.80) , and (6.95±2.31) ng/ml, the CK-MB level was (43.6±23.5) , (1 135.8±180.6) ,and (390.3±121.5) U/L, the LDH level was (119.0±58.6) , (1 838.6±543.8) , and (631.6±228.3) U/L in control group, I/R group and salvianolate+I/R group, all significantly lower in salvianolate+I/R group than in I/R group (all P<0.01) . (3) The rate of TUNEL positive myocardial cells were (1.07±1.16) %, (21.36±4.11) %,and (13.30±3.67) % in control group, I/R group,and salvianolate+I/R group (all P<0.01) . (4) The cleaved Caspase-3 expression was 0.11±0.05, 0.84±0.20,and 0.43±0.09 in control group, I/R group, and salvianolate+I/R group (all P<0.01) . (5) The ATP level of myocardial tissue was (100.0±0.0) %, (34.2±9.2) %,and (62.1±18.0) % respectively in control group, I/R group, and salvianolate+I/R group (all P<0.01) . (6) There was almost no 8-OHdG expression in the myocardial tissue of control group. The expression of 8-OHdG in the myocardial tissue of I/R group was greater than that of the control group. The expression of 8-OHdG in the myocardial tissue of salvianolate+I/R group was less than that of the I/R group. Conclusion: Salvianolate may alleviate myocardial I/R injury of rat through reducing the mitochondrial DNA oxidative damage, protecting mitochondrial function and inhibiting the apoptosis of myocardial cells.

Abstract
Ceratovacuna lanigera Zehntner is a major leaf pest of sugarcane. Widely distributed, it affects both the yield and quality of sugarcane in China. This study aimed to assess real yield and sugar yield losses, and the effect of C. lanigera damage on emergence of newly planted and ratoon cane under current production levels. Field experiments were carried out from 2014 to 2016 in Yunnan Province China. At maturity, plants were harvested and weighed to determine yield, and the effect on sugarcane quality and sucrose content analyzed. Real yield decreased by average of 46,185 kg hm-2 (range: 37,545-61,845 kg hm-2) in damaged versus undamaged areas, with an average yield loss rate of 35.9% (28.5-45.7%). Juice yield decreased by an average of 3.01% (2.4-4.13%) and sucrose content by 6.38% (5.48-8.16%). Juice brix decreased by an average of 7.66°BX (6.95-9.05°BX) and juice gravity purity by 12.35% (8.43-19.97%). In contrast, the reducing sugar content increased by an average of 1.21% (1.01-1.3%). Emergence rates of newly planted cane decreased by an average of 26.0% (24.7-27.3%). The emergence number of ratoon cane decreased by 66,834 hm2 (57,429-76,238 hm-2) and relative emergence loss rates of ratoon cane decreased by an average of 57.8% (57.6-58.0%). These findings confirm that C. lanigera damage severely affects sugarcane yield and quality in Yunnan Province. The results will help the implementation of effective control measures, thereby supporting sustainable development of the Chinese sugar industry.

Abstract
Objective: To investigate the impact of blood pressure and age on arterial stiffness in general population. Methods: Participants who took part in 2010, 2012 and 2014 Kailuan health examination were included. Data of brachial ankle pulse wave velocity (baPWV) examination were analyzed. According to the WHO criteria of age, participants were divided into 3 age groups: 18-44 years group (n=11 608), 45-59 years group (n=12 757), above 60 years group (n=5 002). Participants were further divided into hypertension group and non-hypertension group according to the diagnostic criteria for hypertension (2010 Chinese guidelines for the managemengt of hypertension). Multiple linear regression analysis was used to analyze the association between systolic blood pressure (SBP) with baPWV in the total participants and then stratified by age groups. Multivariate logistic regression model was used to analyze the influence of blood pressure on arterial stiffness (baPWV≥1 400 cm/s) of various groups. Results: (1)The baseline characteristics of all participants: 35 350 participants completed 2010, 2012 and 2014 Kailuan examinations and took part in baPWV examination. 2 237 participants without blood pressure measurement values were excluded, 1 569 participants with history of peripheral artery disease were excluded, we also excluded 1 016 participants with history of cardiac-cerebral vascular disease. Data from 29 367 participants were analyzed. The age was (48.0±12.4) years old, 21 305 were males (72.5%). (2) Distribution of baPWV in various age groups: baPWV increased with aging. In non-hypertension population, baPWV in 18-44 years group, 45-59 years group, above 60 years group were as follows: 1 299.3, 1 428.7 and 1 704.6 cm/s, respectively. For hypertension participants, the respective values of baPWV were: 1 498.4, 1 640.7 and 1 921.4 cm/s. BaPWV was significantly higher in hypertension group than non-hypertension group of respective age groups (P<0.05). (3) Multiple linear regression analysis defined risk factors of baPWV: Multivariate linear regression analysis showed that baPWV was positively correlated with SBP(t=39.30, P<0.001), and same results were found in the sub-age groups (t-value was 37.72, 27.30, 9.15, all P<0.001, respectively) after adjustment for other confounding factors, including age, sex, pulse pressure(PP), body mass index (BMI), fasting blood glucose (FBG), total cholesterol (TC), smoking, drinking, physical exercise, antihypertensive medications, lipid-lowering medication. (4) Multivariate logistic regression analysis of baPWV-related factors: After adjustment for other confounding factors, including age, sex, PP, BMI, FBG, TC, smoking, drinking, physical exercise, antihypertensive medication, lipid-lowering medication, multivariate logistic regression analysis showed that risks for increased arterial stiffness in hypertension group were higher than those in non-hypertension group, the OR in participants with hypertension was 2.54 (2.35-2.74) in the total participants, and same results were also found in sub-age groups, the ORs were 3.22(2.86-3.63), 2.48(2.23-2.76), and 1.91(1.42-2.56), respectively, in each sub-age group. Conclusion: SBP is positively related to arterial stiffness in different age groups, and hypertension is a risk factor for increased arterial stiffness in different age groups.

Abstract
Objective: To investigate the possible mechanism related to the protective effects of salvianolate in H9c2 cells underwent hypoxia/reoxygenation (H/R)-injury. Methods: H9c2 cells were divided into four groups: control group, salvianolate group (S group), H/R group, and salvianolate+ H/R group(S+ H/R group), in which the H9c2 cells were pretreated with salvianolate before H/R-treatment.Apoptotic cells were detected by Tunel assays and AnnexinⅤ-FITC apoptosis detection kit.The intracellular ATP level, the change of mitochondrial membrane potential and the mitochondrial DNA oxidative damage were also determined in these groups. Results: (1) The apoptosis rate of H/R group(26.36±5.14)% was significantly higher compared to control group(2.71±1.66)%(P=0.000 4), which could be significantly reduced in S+ H/R group(17.28±4.75)%(P=0.012 8 vs. H/R group , P=0.003 9 vs. control group). The ratio of AnnexinⅤ and PI double positive cells in H/R group(28.23±6.73)% was significantly higher compared to control group(3.53±2.83)%(P=0.001 1), which was significantly reduced in S+ H/R group(18.10±4.56)%(P=0.037 2 vs. H/R group, P=0.038 3 vs. control group). (2)The ATP level of H9c2 cells in H/R group(49.05±10.12)% was significantly lower than in control group 100%(P=0.000 5), which was significantly increased in S+ H/R group(68.67±13.32)%(P=0.019 9 vs. H/R group). Confocal microscope showed that red fluorescence was dominant in the control group, red fluorescence was significantly reduced, while green fluorescence was significantly increased in H9c2 cells of H/R group and the fluorescence ratio of red to green in H/R group((37.13±8.47)%) was significantly decreased compared to control group (100%, P=0.000 1), fluorescence ratio of red to green was significantly increased in S+ H/R group((63.77±12.32)% vs. H/R group, P=0.007 3). (3)The mitochondrial DNA oxidative damage in different groups: there was only few 8-hydroxyguanine (8-OHdG) expression, which marked as green, in control group, and 8-OHdG expression was significantly upregulated in H/R group, moreover, the 8-OHdG was co-localized with mitochondria.The expression of 8-OHdG was significantly lower in S+ H/R group compared to H/R group. Conclusion: Salvianolate can reduce mitochondrial DNA oxidative damage, and protect mitochondrial function, thus inhibit myocardial cell apoptosis and eventually reduce the myocardial H/R-injury in H9c2 cells.

Abstract
OBJECTIVE To investigate the association between different kinds of systolic blood pressure (SBP, including office, visit-to-visit, 24-hour ambulatory) and vascular damages (represented by carotid intima-media thickness, CIMT; brachial-ankle pulse wave velocity, baPWV) in the elderly. METHODS A total of 2 814 participants aged of ≥60 years old and retired employees were selected with random sampling method from the individuals who took part in 2006-2007, 2008-2009, 2010-2011 health examination in Tangshan Kailuan Hospital, Kailuan Linxi Hospital, Kailuan Zhaogezhuang Hospital and with 24-hour ambulatory blood pressure monitoring data, CIMT and baPWV.Finally, 2 146 participants (1 438 males, average age (67.3±6.0) years old) were included to the analysis.Multivariable regression analysis was used to analyze association between the office, visit-to-visit, 24-hour, day-time, night-time SBP and CIMT and baPWV, respectively. RESULTS (1) The average SBP, DBP, CIMT and baPWV were (137.0±20.4) mmHg(1 mmHg=0.133 kPa), (83.5±11.0) mmHg, (0.92±0.18)mm and (1 781.7±353.2)cm/s.(2) The participants were divided into high and low level groups according to the median of different SBPs, respectively.The results indicated that CIMT and baPWV were significantly higher in high level groups than in low level groups (all P<0.01). (3) After adjusting for gender and age, the partial correlate analysis showed that the office, visit-to-visit, 24-hour, day-time, night-time SBP positively associated with CIMT and baPWV (all P<0.01). (4) After adjusting for confounding factors, multivariable regression analysis showed that the office, visit-to-visit, 24-hour, day-time, night-time SBP were positively and linearly associated with CIMT and baPWV in total cohort, and standard regression coefficients were 0.157, 0.208, 0.175, 0.169, 0.163, 0.479, 0.420, 0.401, 0.389 and 0.354, respectively.In addition, similar results were observed in male and female participants but there was no significance between night-time SBP and CIMT in female participants. CONCLUSIONS Office, visit-to-visit, 24-hour, day-time, night-time SBP are associated with vascular damages, and the best associations are observed between visit-to-visit SBP and vascular function damage.

Abstract
OBJECTIVE To investigate the effects of lycopene on primary cultured neonatal mouse cardiomyocytes with hypoxia/reoxgenation (H/R) injury and explore related mechanism. METHODS Primary cultured neonatal mouse cardiomyocytes were randomly divided to control group (control); lycopene group (5 μmol/L, lyc); H/R group (4 hours hypoxia followed by 6 hours reoxgenation); lycopene+ H/R group (lyc+ H/R, the cardiomyocytes were incubated with 5 μmol/L lycopene for 4 hours before H/R treatment). The cell viability of cardiomyocytes was assessed by CCK-8 assay. The apoptotic rate of cardiomyocytes was evaluated by flow cytometry using AnnexinV-PI double staining. Western blot was used to determine the GRP78, CHOP, Bax and Bcl-2 protein expression in cardiomyocytes. The mRNA expressions of ATF6、eIF2α and sXbp-1 were detected by real-time PCR. The fluorescence intensity for reactive oxygen species (ROS) in cardiomyocytes was measured with Olympus fluorescence microscope. RESULTS Compared to control group, the cell viability of cardiomyocytes was significantly reduced ((64.28±6.12)% vs. (100.00±4.98)%, P<0.01), the apoptotic rate ((24.42±1.76)% vs. (5.16±1.31)%, P<0.01) and ratio of Bax/Bcl-2 (2.33±0.20 vs. 1.00±0.09, P<0.01) significantly increased, the ATF6, eIF2α and sXbp-1 mRNA expression, the CHOP and GRP78 protein expression (1.98±0.15 vs. 1.00±0.12, 2.09±0.11 vs. 1.00±0.09) as well as fluorescence intensity for ROS ((262.13±22.03)% vs. (100.00±12.35)%) were markedly increased in H/R group (all P<0.01). Compared to the H/R group, pretreatment with lycopene markedly improved the cell viability of cardiomyocytes ((81.75±6.85)%, P<0.01), significantly decreased the apoptotic rate ((17.24±2.02)%, P<0.01) and ratio of Bax/Bcl-2(1.64±0.13, P<0.01), significantly down-regulated the mRNA expression levels of ATF6, eIF2α and sXbp-1, and the protein expression levels of CHOP (1.54±0.12) and GRP78 (1.53±0.12), significantly reduced the fluorescence intensity for ROS ((171.18±19.09)%, all P<0.01). CONCLUSIONS Lycopene could attenuate hypoxia/reoxygenation-injury in primary cultured neonatal mouse cardiomyocytes, possibly through inhibiting the ER stress and alleviating the ER stress-induced apoptosis.

Abstract
OBJECTIVE To investigate the financial burden of patients who had various stages of hepatitis B virus-related diseases and the level of alleviation from financial burden by health insurance schemes in Yunnan province of China. STUDY DESIGN A cross-sectional survey. METHODS Patients' information was consecutively recorded at the First Affiliated Hospital of Kunming Medical University, from December 2012 to June 2013. Consecutive cases of hepatitis B virus (HBV) (520), compensated cirrhosis (91), decompensated cirrhosis (198) and hepatocellular carcinoma (HCC) (131) were recruited from the outpatient and inpatient departments. The total direct costs, hospital charge, outpatient costs, hospitalization fees being reimbursed and household catastrophic health expenditure were estimated for each disease group. RESULTS The average annual direct costs for each disease group were 19,496 RMB for HBV, 28,466 RMB in compensated cirrhosis, 46,061 RMB for decompensated cirrhosis, and 33,044 RMB for HCC patients. Catastrophic health expenditure occurred in all four groups. Health insurance reimbursement released the financial burden incurred by medical expenses of patients under a high level of household economic status. Public health insurance schemes helped the patients to various extents. CONCLUSIONS Among these patient groups, direct costs represent a significant economic burden. Health expenditure and financing systems must be considered to prevent the increase of household catastrophe, particularly among the poor.

Abstract
Biofilm formation and the production of extracellular polymeric substances (EPS) by meso- and thermoacidophilic metal-oxidizing archaea on relevant substrates have been studied to a limited extent. In order to investigate glycoconjugates, a major part of the EPS, during biofilm formation/bioleaching by archaea on pyrite, a screening with 75 commercially available lectins by fluorescence lectin-binding analysis (FLBA) has been performed. Three representative archaeal species, Ferroplasma acidiphilum DSM 28986, Sulfolobus metallicus DSM 6482T and a novel isolate Acidianus sp. DSM 29099 were used. In addition, Acidianus sp. DSM 29099 biofilms on elemental sulfur were studied. The results of FLBA indicate (i) 22 lectins bound to archaeal biofilms on pyrite and 21 lectins were binding to Acidianus sp. DSM 29099 biofilms on elemental sulfur; (ii) major binding patterns, e.g. tightly bound EPS and loosely bound EPS, were detected on both substrates; (iii) the three archaeal species produced various EPS glycoconjugates on pyrite surfaces. Additionally, the substratum induced different EPS glycoconjugates and biofilm structures of cells of Acidianus sp. DSM 29099. Our data provide new insights into interactions between acidophilic archaea on relevant surfaces and also indicate that FLBA is a valuable tool for in situ investigations on archaeal biofilms.

Abstract
A laccase, with HIV-1 reverse transcriptase inhibitory activity (IC(50)=12.7 μM) and antiproliferative activity against HepG2 cells (IC(50)=5.6 μM) and MCF7 cells (IC(50)=6.5 μM), was purified from fresh fruiting bodies of the edible white common Agrocybe cylindracea mushroom. The laccase, which had a novel N-terminal sequence, displayed a molecular mass of 58 kDa within the range reported for most other mushroom laccases. The purification protocol entailed ion exchange chromatography on DEAE-cellulose, SP-Sepharose, and Q-Sepharose and gel filtration on Superdex 75. The laccase was adsorbed on DEAE-cellulose and Q-Sepharose, but unadsorbed on SP-Sepharose. Its optimum pH was pH 3-4 and its optimum temperature was 50°C. The activity of the isolated laccase differed from one substrate to another. The ranking was ABTS>N,N-dimethyl-1,4-phenylenediamine>hydroquinone>catechol>2-methylcatechol>pyrogallol.

Abstract
Narrow, red stripes were observed on leaves and sheaths of sugarcane in 2007 in DanZhou County of Hainan Province and XuWen County of GuangDong Province, China. Stripes were parallel to the leaf veins. Some stripes were short (2 to 10 cm) and some were >1 m long, extending from the base of leaves. Width of the stripes was 2 to 4 mm. Symptoms varied with the cultivar. Cv. Taiwang 25, which was the most affected, exhibited red stripes and stalk death from the apex. Cvs. Taiwang 26 and Guang Dong 00236 were slightly affected with only red stripes. Symptoms on cv. Taiwang 22 were mottled stripes. Severe losses were observed in the infected fields that were planted with cv. Taiwang 25, but there were no obvious losses in fields planted with the other three cultivars. Isolations were made from 10 individual plants from different cultivars and provinces that had red stripes, two of which also had apex death. Five independent bacterial isolates were obtained from tissue showing the red stripe symptoms on potato dextrose agar medium. The percentage of positive samples was 50%. No bacteria were obtained from necrotic apex tissue. Bacterial cells were 0.92 to 1.55 × 0.20 to 0.22 μm slightly curved rods that were motile with one to two polar flagella. Colonies on nutrient agar were 2 to 3 mm in diameter, circular, smooth, entire, and milky white. Colonies on King's medium B were nonfluorescent under 365-nm UV light. Five bacterial strains were inoculated by injecting bacterial suspensions (1 × 108 CFU/ml) into the base of the leaves of 6-month-old cv. Taiwang 25 plants (1). Red stripes appeared 7 to 10 days after inoculation and bacteria were reisolated. The reisolated bacteria were identical to the original strains in colony morphology and 16S rDNA sequence. A hypersensitive response appeared within 24 h when 1 × 108 CFU/ml bacteria suspensions were infiltrated into tobacco leaves. Approximately 1,000-bp DNA fragments were amplified with universal primers UP1 (5'-TACGTGCCAGCAGCCGCGGTAATA-3') and UP2 (5'-AGTAAGGAGGGTATCCAACCGCA-3') (3). Primers UP1 and UP2 are complementary to nucleotide sequence 509 to 523 and 1541 to 1522, respectively, of the Escherichia coli 16S rDNA gene. The fragment amplified by these primers was approximately 1,032 bp. The 16S rDNA sequences of the five strains were deposited in GenBank as Accession Nos. GQ476791-5. They all shared 99% nucleotide identity with the type strain of Herbaspirillum rubrisubalbicans (GenBank No. AJ238356.1). All five strains were identified as H. rubrisubalbicans on the basis of 16S rDNA sequence and pathogenicity to sugarcane, and the disease was identified as mottled stripe disease (2). Since we were not able to isolate bacteria from necrotic apex tissue, this symptom on cv. Taiwang 25 may not be related to the H. rubrisubalbicans infection. To our knowledge, this is the first report of mottled stripe disease in China. References: (1) H. M. A. EI-Komy et al. Folia Microbiol. 48:787, 2003. (2) A. S. Saumtally et al.

Abstract
Percutaneous transluminal coronary angioplasty (PTCA) of chronic total occlusions may be technically difficult and the success rate is limited despite increasing operator experience and improvements in PTCA hardware. The number of guidewires required to cross totally occluded lesions is higher than that for stenotic lesions. The ChoICE polymer-tip (PT) wire (Boston Scientific/Scimed, Inc., Maple Grove, Minnesota) is a relatively new stainless-steel core wire with a hydrophilic-coated polyurethane tip. Though never described in the literature, we found that the distal 4 cm of the wire can be cut and reshaped according to the operator's needs. Thus, instead of reshaping a kinked tip or using another new wire, the former being time-consuming and the latter expensive, one can simply cut off the kinked tip and start again with a "new wire." As the tip is resected, the wire becomes progressively more "intermediate-like" and "standard-like." We report our experience with the ChoICE PT wire in 50 consecutive cases of chronic total occlusions. The cumulative crossing success rates were 13/50 (26%) before any resections, 24/50 (48%) after 1 resection, 41/50 (82%) after 2 resections and 42/50 (84%) after 3 resections. There were no perforations, deaths, myocardial infarctions or need for bypass surgery. Our findings suggest that successful recanalization of chronic total occlusions can be achieved with a high success rate using the ChoICE PT wire. A strategy of progressively resecting the more floppy and kinked distal end can provide multiple uses from a single wire, optimizing recanalization success and obviating the need for additional wires.
