Abstract
Warfarin is an irreplaceable oral anticoagulant for patients with mechanical heart valves, the stable pharmacogenetic-based warfarin dose prediction algorithms have improved the effectiveness and safety of warfarin anticoagulation therapy. Genetic factors are the main factors affecting the stable dose of warfarin. Single nucleotide polymorphisms such as VKORC1 and CYP2C9 affect the anticoagulation effect of warfarin through pharmacodynamic or pharmacokinetic pathways. Age, body surface area, combined use of drugs, and other nongenetic factors also affect the stable dose of warfarin. Previously published algorithms for warfarin dose prediction included mainly the white race, and most algorithms were constructed using traditional multiple linear regression. However, domestic studies have used machine learning methods to construct warfarin dose prediction algorithms based on the Chinese Han post-mechanical valve replacement population and have achieved better prediction efficiency. This article reviews the advances of warfarin anticoagulation influencing factors and the clinical application of stable dose prediction algorithms.

Abstract
Glucose oxidase (GOX) is a representative compound found in most insect saliva that can suppress plant-defensive responses. However, little is known about the origin and role of GOX in the crucifer-specialized pest Plutella xylostella. In this study, we showed obvious regurgitation from the larval gut of P. xylostella and identified abundant peptides highly similar to known GOX. Three PxGOX genes were verified with PxGOX2 preferentially expressed in the gut. The heterologously expressed PxGOX2 confirmed its function to be a GOX, and it was detected in plant wounds together with the gut regurgitant. Further experiments revealed that PxGOX2 functioned as an effector and may suppress defensive responses in plant through the production of H2O2, which modulates levels of antagonistic salicylic acid and jasmonic acid. However, excessive H2O2 in the host plant may be neutralized by peroxidase, thus forming defensive feedback. Our findings provided new insights into understanding the GOX-mediated insect-plant interactions.

Abstract
Objective: To summarize clinical features and our experience of the diagnosis and treatment of laryngocele. Methods: Clinical data of 11 laryngocele patients in department of Otorhinolaryngology Head and Neck Surgery of the Second Affiliated Hospital of Shanxi Medical University from January 2012 to December 2021 were retrospectively reviewed, including 9 men and 2 women, aged from 12 to 75 years, with median age of 56 years. Electronic laryngoscope was performed in 10 of all patients, laryngeal CT in 10 and cervical color ultrasound in 5 before operation.All the operations were performed under general anesthesia, and the external cervical approach was used for external and combined laryngocele. The internal laryngocele was resected by low temperature plasma through transoral endoscopy. Patients were followed up regularly after operation to evaluate the effect. Clinical feature, types of lesions, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eleven laryngocele patients were divided into mixed type (n=6), internal type (n=4) and external type (n=1).Nine patients presented with hoarseness or dysphonia, 7 with cervical mass and 1 with airway obstruction. Surgical resections were done through external cervical approach (n=7)or transoral endoscopic approach (n=4). All the operations were successful and no complication occurred. All cases were followed up from 17 to 110 months. No recurrence was encountered. Conclusions: Laryngocele is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and electronic laryngoscope is essential to evaluate the location, and extent of the lesion, and to make the surgical plan.Complete surgical excision is required. Surgical resection is the only effective method for the treatment of laryngocele.

Abstract
Objective: To evaluate the predictive value of the proportion of hibernating myocardium (HM) in total perfusion defect (TPD) on reverse left ventricle remodeling (RR) after coronary artery bypass graft (CABG) in patients with heart failure with reduced ejection fraction (HFrEF) by 99mTc-methoxyisobutylisonitrile (MIBI) single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with 18F-flurodeoxyglucose (FDG) gated myocardial imaging positron emission computed tomography (PET). Methods: Inpatients diagnosed with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2016 to January 2022 were prospectively recruited. MPI combined with 18F-FDG gated PET was performed before surgery for viability assessment and the patients received follow-up MPI and 18F-FDG gated PET at different stages (3-12 months) after surgery. Δ indicated changes (post-pre). Left ventricular end-systolic volume (ESV) reduced at least 10% was defined as RR, patients were divided into reverse remodeling (RR+) group and the non-reverse group (RR-). Binary logistic regression analysis was used to identify predictors of RR. Receiver operating characteristic (ROC) curve analysis was performed and the area under the curve (AUC) was calculated to assess the cut-off value for predicting RR. Additionally, we retrospectively enrolled inpatients with HFrEF at the Cardiac Surgery Center, Anzhen Hospital of Capital Medical University from January 2021 to January 2022 as the validation group, who underwent MPI and 18F-FDG gated PET before surgery. Echocardiography was performed before CABG and after CABG (3-12 months). In the validation group, the reliability of obtaining the cut-off value for the ROC curve was verified. Results: A total of 28 patients with HFrEF (26 males; age (56.9±8.7) years) were included in the prospective cohort. HM/TPD was significantly higher in the RR+ group than in the RR- group ((51.8%±17.9%) vs. (35.7%±13.9%), P=0.016). Binary logistic regression analysis revealed that HM/TPD was an independent predictor of RR (Odds ratio=1.073, 95% Confidence interval: 1.005-1.145, P=0.035). ROC curve analysis revealed that HM/TPD=38.3% yielded the highest sensitivity, specificity, and accuracy (all 75%) for predicting RR and the AUC was 0.786 (P=0.011). Meanwhile, a total of 100 patients with HFrEF (90 males; age (59.7±9.6) years) were included in the validation group. In the validation group, HM/TPD=38.3% predicted RR in HFrEF patients after CABG with the highest sensitivity, specificity and accuracy (82%, 60% and 73% respectively). Compared with the HFrEF patients in the HM/TPD<38.3% group (n=36), RR and cardiac function improved more significantly in the HM/TPD≥38.3% group (n=64) (all P<0.05). Conclusions: Preoperative HM/TPD ratio is an independent factor for predicting RR in patients with HFrEF after CABG, and HM/TPD≥38.3% can accurately predict RR and the improvement of cardiac function after CABG.

Abstract
According to World Health Organization (WHO) survey, air pollution has become the major reason of several fatal diseases, which had led to the death of 7 million peoples around the globe. The 9 people out of 10 breathe air, which exceeds WHO recommendations. Several strategies are in practice to reduce the emission of pollutants into the air, and also strict industrial, scientific, and health recommendations to use sustainable green technologies to reduce the emission of contaminants into the air. Photocatalysis technology recently has been raised as a green technology to be in practice towards the removal of air pollutants. The scientific community has passed a long pathway to develop such technology from the material, and reactor points of view. Many classes of photoactive materials have been suggested to achieve such a target. In this context, the contribution of conjugated polymers (CPs), and their modification with some common inorganic semiconductors as novel photocatalysts, has never been addressed in literature till now for said application, and is critically evaluated in this review. As we know that CPs have unique characteristics compared to inorganic semiconductors, because of their conductivity, excellent light response, good sorption ability, better redox charge generation, and separation along with a delocalized π-electrons system. The advances in photocatalytic removal/reduction of three primary air-polluting compounds such as CO2, NOX, and VOCs using CPs based photocatalysts are discussed in detail. Furthermore, the synergetic effects, obtained in CPs after combining with inorganic semiconductors are also comprehensively summarized in this review. However, such a combined system, on to better charges generation and separation, may make the Adsorb & Shuttle process into action, wherein, CPs may play the sorbing area. And, we hope that, the critical discussion on the further enhancement of photoactivity and future recommendations will open the doors for up-to-date technology transfer in modern research.

Abstract
Objective: To compare the efficacy of off-pump coronary artery bypass grafting (CABG) or CABG plus mitral valve plasty (MVP) in patients with coronary heart disease complicated with moderate ischemic mitral insufficiency. Methods: The clinical data of 1 050 patients with coronary heart disease complicated with moderate ischemic mitral insufficiency who underwent surgical procedures from January 2009 to December 2020 were analyzed retrospectively. There were 733 males and 317 females, aging (63.3±9.0) years (range: 31 to 83 years). Patients were divided into CABG+MVP group and CABG group according to surgical methods, and the two groups of patients were matched for 1∶4 by the propensity score matching method. There were 107 patients in the CABG+MVP group and 406 patients in the CABG group after matching. The t test, Mann-Whitney U test, χ2 test, Fisher's exact probability method and repeated measures anova were used to compare the surgical outcomes and overall survival in the two groups. Results: There were no significant differences in perioperative death and postoperative complications between the two groups (all P>0.05). Compared with CABG group, CABG+MVP group had longer operation time ((5.6±1.2) hours vs. (4.2±1.0) hours, t=11.528, P<0.01), ICU stay(M(IQR))(43.0(47.3) hours vs. 25.0(33.6) hours, Z=2.483, P=0.013), and postoperative hospital stay (8(4) days vs. 7(5) days, Z=2.143, P=0.032). The amount of erythrocyte and platelet used in CABG+MVP group was significantly increased (2.0(6.5) U vs. 0(2.0) U, Z=7.084, P<0.01; 0(0.5) U vs. 0(0) U, Z=5.210, P<0.01). A total of 463 cases (93.9%) were followed up. Median follow-up was 32(31) months (range: 3 to 105 months). There was no significant difference in overall survival and no major adverse cardic and cerebrovascular events survival between CABG group and CABG+MVP group (P=0.196,P=0.305). Echocardiography showed that there was no significant difference in ejection fraction left ventricular end-diastolic diameter between the two groups (F=0.322, P=0.571; F=0.681, P=0.410). However, CABG+MVP improved mitral regurgitation better than CABG (F=160.222, P<0.01). Conclusions: For patients with coronary heart disease with moderate ischemic mitral insufficiency, the rates of all-cause mortality and major adverse cardiac and cerebrovascular events are similar between the two surgeries. Although CABG+MVP improves mitral regurgitation better than CABG, it increases the duration of surgery, ICU stay, postoperative hospital stay, and blood transfusion requirement.

Abstract
Objective: To in vestigate the death-related risk factors of surgical treatment of myocardial infarction (MI) combined with ventricular septal rupture (VSR). Methods: The clinical data of patients (68 cases) with ventricular septal rupture after myocardial infarction (PI-VSR) from January 2008 to December 2020 in Beijing Anzhen Hospital were retrospectively selected and analyzed. We followed up the surviving patients and divided them into the survival group and the death group according to the perioperative and follow-up results. The univariate analysis was performed on various indicators, and the Cox regression analysis was used to analyze the risk factors related to postoperative death. Results: A total of 68 patients (42 were male and 26 were female, with age 44-82 (64.3±8.2) years after surgical treatment of myocardial infarction combined with ventricular septal rupture were enrolled, 9 patients died during the perioperative period, 59 surviving patients were followed up for 0.1-10.5 years(mean, 4 years), and 7 deaths during follow-up. Based on this, 52 patients were selected as the survival group while 16 patients as the death group. The results of univariate analysis showed that age, VSR to operation time less than 7 days, killip grade ≥ grade 3, cardiogenic shock, preoperative use of IABP, emergent surgery were related to postoperative death. The factors with P<0.2 factors in univariate analysis were selected into the multivariate Cox regression analysis. Age ([OR=1.110(1.012-1.217), P=0.026], platelet count [OR=0.990(0.981-0.999), P=0.031], D dimer (OR=1.002[1.001-1.003], P=0.003), cardiogenic shock (OR=6.084[1.729-21.405], P=0.005) were independent risk factors for postoperative death. All patients were followed up, the survival rate of 2-year, 4-year, 6-year, 8-year, and 10-year was 77.5%, 77.5%, 71.0%, 71.0%, and 71.0%, respectively. Conclusions: Age, platelet count, D-dimer, and cardiogenic shock are risk factors for death after surgical treatment of myocardial infarction combined with ventricular septal rupture. Surgery is an effective method for the treatment of myocardial infarction combined with ventricular septal rupture. Long-term prognosis of the surviving patients during perioperative are relatively better.

Abstract
OBJECTIVE To assess the value of m7G-lncRNAs in predicting the prognosis and microenvironment of colorectal cancer (CRC). METHODS We screened m7G-lncRNAs from TCGA to construct an m7G-lncRNAs risk model using multivariate Cox analysis, which was validated using ROC and C-index curves. Calibration and nomogram were used to predict the prognosis of CRC patients. Point-bar charts and K-M survival curves were used to assess the correlation of risk scores with the patients' clinical staging and prognosis. CIBERSORT and ESTIMATE were used to explore the association between the tumor microenvironment and immune cell infiltration in patients in high and low risk groups and the correlation of risk scores with microsatellite instability, stem cell index and immune checkpoint expression. A protein-protein interaction network was constructed, and the key targets regulated by m7G-lncRNAs were identified and validated in paired samples of CRC and adjacent tissues by immunoblotting. RESULTS We identified a total of 1722 m7G-lncRNAs from TCGA database, from which 12 lncRNAs were screened to construct the risk model. The AUCs of the risk model for predicting survival outcomes at 1, 3 and 5 years were 0.727, 0.747 and 0.794, respectively. The AUC of the nomogram for predicting prognosis was 0.794, and the predicted results were consistent with actual survival outcomes of the patients. The patients in the high-risk group showed more advanced tumor stages and a greater likelihood of high microsatellite instability than those in the low-risk group (P < 0.05). The tumor stemness index was negatively correlated with the risk score (r=-0.19; P=7.3e-05). Patients in the high-risk group had higher stromal cell scores (P=0.0028) and higher total scores (P=0.007) with lowered expressions of activated mast cells (r=-0.11; P=0.045) and resting CD4+ T cells (r=-0.14; P=0.01) and increased expressions of most immune checkpoints (P < 0.05). ATXN2 (P= 0.006) and G3BP1 (P=0.007) were identified as the key targets regulated by m7G-lncRNAs, and their expressions were both higher in CRC than in adjacent tissues. CONCLUSION The risk model based on 12 m7G-lncRNAs has important prognostic value for CRC and can reflect the microenvironment and the efficacy of immunotherapy in the patients.

Abstract
An expert consensus on coronary artery bypass grafting (CABG) in patients with ischemic cardiomyopathy (ICM) was released by the American Association for Thoracic Surgery in May 2021, which contains a vast array of perioperative recommendations. During preoperative period, a comprehensive assessment on ICM including myocardial viability and valve function by a multi-disciplinary team (MDT) approach should be performed. In terms of intraoperative period, multiple arterial conduits and on-pump CABG using cold blood cardioplegia should be considered, meanwhile, other aspects involving concomitant management of mitral valve regurgitation and arrythmia, as well as active use of mechanical cardiac assist devices (e.g., intra-aortic balloon pump) should also be achieved. Finally, a range of postoperative interventions which includes standardized MDT management in intensive care unit (ICU), continuous use of cardiac assist devices, cardiac pacing, close follow-up within 90 days and drug treatment strictly guided by the guidelines after discharge from hospital should be conducted. The above-mentioned perioperative bundled care might reduce perioperative complications and operative mortality, and thus improve the prognosis of the patients with ICM.

Abstract
Many factors still need to be evaluated to fully understand the physical mechanisms determining optical cavity vibration, which are crucial for designing and constructing a transportable ultra-stable laser. Herein, a detailed dynamic analysis is used to characterize the vibration modes of a transportable optical cavity. The first five resonance modes are identified in the presence of a cavity support, and the guidelines to achieve a high first-order resonance frequency are proposed; thereby, high robustness is described using a 50 mm length optical cavity. The results demonstrate that the first-order resonance of up to 681 Hz with a gross weight of 2.51 kg can be achieved using an optimization strategy for given cavity support. The theoretical results are consistent with simulation and experiment. With the optimal group, a 1.34 Hz linewidth transportable ultra-stable laser at 1550 nm is established, and a linewidth of 1.5 Hz and frequency instability of 9.5×10-15@1s are obtained after the test including 100 km actual road transportation and 34 min continuous vibration. The test condition is equivalent to ∼ 1000 km road transportation. Our method can be readily extended to other transportable optical cavities, providing a powerful tool for improving the robustness of vibration, particularly important for transportable environments.

Abstract
OBJECTIVE Acute myocardial infarction (AMI) is a sudden cardiovascular event that endangers human life. MicroRNA is considered to be an important participant in the pathophysiology of myocardial infarction (MI). This article aim was to study the function and mechanisms of microRNA-346 (miR-346) on myocardium after MI. MATERIALS AND METHODS To study the role of miR-346 in MI, we established H2O2-induced H9c2 cell injury model and rat MI model. Real-time polymerase chain reaction (RT-PCR) was used to detect miR-346 expression. Western blot was utilized to measure the expression of Bcl-2, Bax, TNF-α, IL-6 and NFIB. Apoptosis of H9c2 cells was detected by TUNEL staining and flow cytometry. Enzyme-linked immunosorbent assay (ELISA) assay was utilized to measure the levels of TNF-α and IL-6 in supernatant. Assessment of left ventricular function in rats was performed using echocardiography. RESULTS MiR-346 was significantly upregulated in H2O2-treated H9c2 cells and ischemic myocardium. In the H9c2 cell injury model, the expressions of Bax, TNF-α, and IL-6 were greatly increased while Bcl-2 expression was decreased, and the number of TUNEL-positive cells and apoptosis rate were also significantly increased. At the same time, the levels of TNF-α and IL-6 in the cell supernatant were markedly increased. However, after miR-346 expression was suppressed, these results were reversed. The expression of Bcl-2 increased, while the expression of Bax, TNF-α, and IL-6 decreased. The contents of TNF-α and IL-6 in the cell supernatant also decreased significantly. Both the number of TUNEL-positive cells and the apoptosis rate were markedly reduced. After injecting antagomir-346 into the myocardium of rats to silence miR-346, the cardiac function of MI rats was remarkably improved, and the LDH content in the serum of rats also decreased significantly. Using computational predictions tools, Western blotting and Luciferase activity assay, we found that nuclear factor I/B (NFIB) was targeted by miR-346. CONCLUSIONS The expression of miR-346 was increased in H9c2 cells and ischemic myocardium of MI rats. Silencing miR-346 can significantly inhibit the inflammatory response and the apoptosis of cardiomyocytes by targeting NFIB.

Abstract
OBJECTIVE To investigate the effect of microRNA-449 (miRNA-449) on cTnI and cardiac function and reveal the mechanism of Histone deacetylase 1 (HDAC1)-mediated histone deacetylation in cardiomyocytes. MATERIALS AND METHODS First, we used biochemical analysis and Dual-Luciferase reporter gene assay to confirm that HDAC1 and miR-449 having the binding site. Then, the effect of miR-449 inhibited HDAC1 on cTnI gene transcription was observed. In vivo, the effect of histone acetylation on cTnI expression and cardiac function in heart was observed in elderly mice with low expression of cTnI through miR-449 agomiR intervention. RESULTS This study revealed miR-449 can sponge with HDAC1. HDAC1-mediated histone deacetylation was involved in the regulation of cTnI gene expression by HDAC1-mediated acetylation of H3K4 and H3K9 in cTnI promoter regions. In addition, HDAC1-mediated histone deacetylation regulated the binding of the transcription factor GATA4 to the GATA element in the cTnI promoter region and improved cardiac function in elderly mice with low expression of cTnI CONCLUSIONS: MiR-449 can regulate the acetylation of the histones H3K4 and H3K9 of the GATA element in the cTnI promoter region, thereby recruiting the transcription factor GATA4 to the cTnI promoter region, upregulating the cTnI gene expression, and improving cardiac function in elderly mice with low expression of cTnI.

Abstract
Objective: To evaluate long-term clinical outcomes of consecutive patients treated with coronary artery bypass grafting (CABG) and percutaneous coronary intervention(PCI) with drug-eluting stents(DES) for ostial/shaft lesions in unprotected left main coronary artery(ULMCA). Method: A total of 259 patients with isolated ostial/midshaft lesions in unprotected left main coronary artery were enrolled consecutively who received DES implantation or underwent CABG between January 2003 and July 2009 in Beijing Anzhen Hospital. The endpoints of the study were death, repeat revascularization, myocardial infarction (MI) and stroke. Time to the primary endpoint was evaluated according to the Kaplan-Meier method, and the log-rank test was applied to compare the incidence of the endpoint. Adjusted risks for adverse outcomes were compared by multivariate Cox proportional hazard regression analyses. Results: A total of 259 patients were included, including 149 in PCI group and 110 in CABG group. And 193(74.5%) cases were males.The age was (61.4±9.8) years old. The median follow-up was 10.1 years (interquartile range 8.3 to 11.2 years) in the overall patients. There were no significant difference for the incidence of death [37.0% vs. 43.1% ,P=0.143] , MI [34.0% vs. 19.4% ,P=0.866], stroke [6.4% vs. 11.7% , P=0.732], repeart revascularization [33.6% vs. 39.9% ,P=0.522] between PCI group and CABG group before multivariate adjusting,according to the incidence calculated with Kaplan-Meier. After adjusting covariates such as age, left ventricular ejection fraction(LVEF) and serum creatine with multivariate Cox hazard regression model, there was still no significant difference between the two groups. Conclusions: PCI with DES is as effective and safe as CABG in patients with left main ostium/shaft lesion during a median follow-up of 10.1 years.

Abstract
Objective: To explore the short-term outcomes of patients with coronary artery disease (CAD) who underwent coronary artery bypass graft (CABG) with sequential radial artery graft. Methods: Clinical data of patients with CAD who underwent CABG with sequential radial artery graft from August to December 2018 in Beijing Anzhen Hospital was retrospectively analyzed. Computer tomography angiography was employed to evaluate the patency of grafts and the incidence of adverse cardiovascular events was followed up 3 months after surgery. Results: A total of thirty patients were included, with an average age of (60.2±7.3) years old, among whom 83.3% were male, and 93.3% had three-vessel disease detected by coronary angiography. All patients had left internal mammary artery (LIMA) anastomosed to the left anterior descending (LAD) and sequential radial artery graft. Among sequential radial artery grafts, the most frequent anastomosis of sequential radial artery graft was aortic artery (AO)-first diagonal branch (D1)-first obtuse marginal branch (OM1) (13 patients, 43.3%), followed by AO-OM1-second obtuse marginal branch (OM2) (9 patients, 30.0%), and 18 patients also underwent saphenous vein graft. None of 30 patients experienced adverse cardiovascular events during postoperative period in hospital. Three-months follow-up outcomes showed that LIMA-LAD in 1 patient (3.3%) occluded, 3 patients had occluded anastomosis of sequential radial artery graft, 1 patient (3.3%) had heart failure, and 1 patient (3.3%) had recurrent angina. Conclusion: The radial artery could be used as the second arterial graft for CAD patients undergoing CABG with a sequential anastomosis technique, and these patients need regular anti-arterial spasm drug treatment after CABG.

Abstract
BACKGROUND Ten healthy adult Huang-huai white goats were selected and sacrificed by jugular vein bleeding after anaesthesia to observe the distribution characteristics of the histological structure of the intestinal mucosa, goblet cells, IgA, and CD3+ lymphocytes. MATERIALS AND METHODS Three sections of the duodenum, the jejunum, and the ileum were immediately collected and fixed with 4% paraformaldehyde for 72 h to prepare tissue sections. After haematoxylin and eosin, periodic acid Schiff, and immunohistochemical staining was performed, the distribution characteristics of goblet cells, IgA-positive cells, and CD3+ lymphocytes were observed. Results showed high columnar epithelial cells in the duodenum and jejunum of Huang-huai white goat and low columnar epithelial cells in the ileum mucosa. RESULTS Mucopolysaccharides secreted by intestinal goblet cells were mainly neutral, and the number of ileum goblet cells was significantly higher than that of the duodenum and the jejunum (p < 0.05). IgA-positive cells were distributed in the lamina propria of the duodenum, and the number of cells was significantly higher than that in the jejunum and the ileum (p < 0.01). The significant difference was found between the jejunum and the ileum (p < 0.01). The CD3+ cells in the intestinal mucosa were distributed in the lamina propria mucosae, and some of the positive cells in the jejunum were distributed between epithelial cells. CD3+ cells had the largest number in the jejunal lamina propria but had the lowest number in the ileum. CONCLUSIONS The jejunum was significantly higher than the duodenum (p < 0.05), and the ileum was much less than the jejunum (p < 0.01).

Abstract
A multimode self-mixing terahertz-frequency gas absorption spectroscopy is demonstrated based on a quantum cascade laser. A double-metal device configuration is used to expand the laser's frequency tuning range, and a precision-micromachined external waveguide module is used to enhance the optical feedback. Methanol spectra are measured using two laser modes at 3.362 and 3.428 THz, simultaneously, with more than eight absorption peaks resolved over a 17 GHz bandwidth, which provide the noise-equivalent absorption sensitivity of 1.20×10-3 cm-1 Hz-1/2 and 2.08×10-3 cm-1 Hz-1/2, respectively. In contrast to all previous self-mixing spectroscopy, our multimode technique expands the sensing bandwidth and duty cycle significantly.

Abstract
Objective: To explore the effect of metformin on murine model of bleomycin (BLM)-induced lung injury and fibrosis. Methods: A total of 30 mice were divided into 3 groups: control, BLM, and BLM with metformin, in accordance with the random number table and each group had 10 mice. To induce the pulmonary fibrosis model, a concentration of 2 mg/ml bleomycin was intratracheally administered in the BLM group and BLM with metformin group with a volume of 1.75 μl/g, while the control group accepted saline with the same volume. Metformin (200 mg/kg) was given to the mice orally once a day from the day before intratracheal instillation of bleomycin to day 14. The daily survival condition of mice was recorded during 14 days. At day 14, HE-staining was used to assess the severity of fibrosis according to the method proposed by Ashcroft. Total lung collagen content was determined by hydroxyproline assay and Masson's trichrome staining. To examine the expression of fibronectin we used the method of immunohistochemistry staining. The changes of Transforming Growth Factor beta 1 (TGF-β(1)) in plasm, bronchoalveolar lavage fluid (BALF) and lung were measured by ELISA. Results: The survival rates of control group, BLM group and BLM with metformin group at day 14 were 10/10, 4/10 and 7/10 respectively. According to the method proposed by Ashcroft the score of metformin treated mice was significantly lower than that of the bleomycin model mice[(3.82±0.58) vs (7.79±0.06), (P<0.05)]. The hydroxyproline level in lung tissue were markedly attenuated in metformin treated mice compared with bleomycin model mice [(0.40±0.05) vs (0.73±0.10) μg/mg, (P<0.05)]. The level of TGF-β(1) in plasma, BALF and lung tissue were also decreased in mice treated with metformin compared with bleomycin model mice [(2.32±0.68) vs (4.59±0.45) ng/ml, (0.81±0.09) vs (1.40±0.06) ng/ml, (17.12±0.83) vs (21.25±0.69) ng/mg, all P<0.05]. Conclusion: Metformin can reduce the severity of pulmonary fibrosis in mice induced by bleomycin.

Abstract
Objective: To evaluate the role of water-soluble C(60) fullerenes in mice model of lung injury and fibrosis that induced by bleomycin. Methods: A total of 20 healthy C57BL/6J mice were randomly divided into normal control group, bleomycin group, high dose C(60) group, low dose C(60) group, each group with 5 mice. Mice were induced pulmonary fibrosis by intratracheal injection of bleomycin except the normal control group, which was induced by saline instead. In low dose C(60) group and high dose C(60) group, 1 mg·kg(-1)·d(-1) and 10 mg·kg(-1)·d(-1) water-soluble C(60) fullerenes was injected into mice intraperitoneally every day, which began from one day before intratracheal instillation of bleomycin until the end of observation. Saline was given to mice in the same way in normal control and bleomycin group. This study investigated the variation of weight and survival rate of mice for 14 d. HE-staining and Masson's trichrome staining were used to assess the severity of fibrosis according to the method proposed by Ashcroft at 14th day. Total lung collagen content was determined by hydroxyproline assay. The changes of transforming growth factor-β(1) (TGF-β(1)) and tumor necrosis factor α (TNF-α) in plasma, bronchial alveolar lavage fluid (BALF) and lung tissue were measured by enzyme-linked immunosorbent assay (ELISA). And, the amount of reactive oxygen species (ROS) was tested by 2, 7-dichlorofuorescin diacetate (DCFH-DA), and determined by the ratio of fluorescence intensity and protein content (OD/μg). Results: C(60) can protect mice that injured by bleomycin from weight loss. According the method proposed by Ashcroft et al.HE and Masson's trichrome staining showed that collagen deposition in lung tissue were markedly attenuated in C(60) (1 mg·kg(-1)·d(-1) and 10 mg·kg(-1)·d(-1)) treated mice compared with bleomycin model mice[(4.08±0.52), (3.00±0.41) vs (6.75±0.75) points, both P<0.01]. In low dose C(60) group and high dose C(60) group, the content of hydroxyproline in lung tissue were significantly lower than that in bleomycin group[(0.36±0.06), (0.35±0.08) vs (0.55±0.16) μg/mg, both P<0.05]. The level of TGF-β(1) in BALF and lung tissue were also decreased in mice treated with C(60) (10 mg·kg(-1)·d(-1)) compared with bleomycin model mice, but the difference had no statistical significance[(9.38±5.32) vs (23.60±8.96) pg/ml, (2.89±0.35) vs (6.44±2.95) pg/mg, both P>0.05]. Also, in high dose C(60) group, the content of TNF-α in plasma, BALF and lung tissue were significantly lower than those in bleomycin group[(4.56±0.73) vs (7.21±2.26) pg/ml, (34.58±23.30) vs (151.00±27.34) pg/ml, (22.99±5.83) vs (122.90±22.04) pg/mg, all P<0.05]. In addition, Compared with bleomycin group, ROS in lung tissue was significantly decreased after treatment with C(60) (10 mg·kg(-1)·d(-1))[(19.68±0.91) vs (22.92±1.71) OD/μg, P<0.05]. Conclusion: Water-soluble C(60) fullerenes reduce the severity of pulmonary fibrosis induced by bleomycin in mice.

Abstract
Objective: To evaluated early clinical outcomes of saphenous vein grafts harvested with a No-touch technique in off-pump coronary artery bypass graft (OPCABG) surgery. Methods: A total of 124 patients with three-vessel disease undergoing OPCABG by No-touch technique between June and November 2017 in Beijing An Zhen Hospital were respectively reviewed. Results: The average age of patients was (60.7±10.3) years, and 80 cases (64.5%) were male, with the average body mass index (BMI)of (25.4±2.5) kg/m(2,) the mean preoperative left ventricular ejection fraction (LVEF) of (58.0±7.0%). The operative time was (4.0±0.4) hours, and 16 cases (12.9%) were harvested for whole vein grafts. The number of vein grafts and venous anastomoses was 144 and 284, respectively. There were 16 cases of single bridge NTSVG-LAD, 4 cases of single bridge NTSVG-D, 99 cases of sequential bridge NTSVG-OM-PDA, 5 cases of sequential bridge NTSVG-OM-PLV, 4 cases of sequential bridge NTSVG-OM-RCA, 16 cases of sequential bridge NTSVG-D-OM-PDA. The mean flow volume of No-touch vein grafts was (51.9±2.4) ml/min. There was no death case in hospital. Postoperative re-exploration for hemorrhage of anastomosis happened in 1 case (0.8%), which was caused by pericardial tamponade due to insufficiency of hemostasis in internal mammary bed. There were 1 case of bad wound healing of lower extremity incision (0.8%). A total of 124 cases were followed up after operation, and the follow-up rate was 100%. There was one all-cause death (0.8%) 27 days after the operation. Conclusion: The short-term clinical observation of the application of No-touch great saphenous vein harvesting technique for OPCABG is safe and effective.

Abstract
Objective: To explore short-term clinical outcomes and risk factors associated with in-hospital mortality in patients undergoing off-pump coronary artery bypass grafting (OPCABG) and establish a prediction model for in-hospital mortality. Methods: The clinical data of patients undergoing OPCABG in Beijing Anzhen Hospital between January 2014 and January 2016 was retrospectively studied. Univariate analysis and logistic regression were applied to determine the potential risk factors, and then a prediction model for mortality was confirmed. The calibration and discrimination of the prediction model was finally tested. Results: A total of 2 546 patients who underwent OPCABG were recruited. In-hospital mortality of OPCABG was 0.7% (17 cases). Seven variables: female, age, left main disease >50%, low left ventricular ejection fraction (LVEF), acute myocardial infarction before surgery, operative status (selective or emergent), moderate concomitant mitral valve regurgitation were independently correlated with OPCABG mortality (all P<0.05). The result of Hosmer-Lemeshow test was χ(2)=5.912, P=0.676. The area under receiver-operating characteristic curve (ROC) was 0.881. Conclusions: OPCABG is safe and effective for myocardial revascularization in a short term. The following risk factors are associated with an increased operative mortality of OPCABG: male, age, left main disease >50%, low LVEF, acute myocardial infarction before surgery, operative status (selective or emergent), moderate concomitant mitral valve regurgitation. The prediction model established by above-mentioned potential risk factors was proven to perform well by statistical tests.

Abstract
A 17-year-old young man with a history of swollen leg and intermittent jaundice was presented to Peking Union Medical College Hospital with acute fever and mental disturbance. He developed deep venous thrombosis, acute myocardial infarction and plantar skin necrosis during the past four years, and was presented with an acute episode of fever, thrombocytopenia, acute kidney injury, acute myocardial infarction, mental disturbance, and obstructive jaundice. Laboratory tests showed schistocytes on peripheral blood smear.High titer of antiphospholipid antibodies was detected.Strikingly, the activity of a disintegrin and metalloprotease with a thrombospondin type 1 motif, member 13 (ADAMTS13)was significantly decreased without the production of inhibitors. Images indicated stenosis of the common bile duct, common hepatic duct, and cystic duct, which caused dilation of bile ducts and the gall bladder. Corticosteroids and anticoagulation therapy were effective at first, but the disease relapsedonce the corticosteroids tapered down. Plasma exchange was administrated for 17 times, which was effective temporarily during this episode. Methylprednisolone pulse therapy, intravenous immunoglobulin, rituximab, anticoagulation therapy, and bile drainage, were all tried but still could not control the disease. The patient's family agreed to withdraw treatment after he developed septic shock.

Abstract
Objective: To discuss the clinical safety and efficacy about off-pump coronary artery bypass grafting (OPCABG) in octogenarians. Methods: From June 2005 to July 2014, 252 patients (male 208, female 44, with a mean age of 81.7 years old) underwent OPCABG in Beijing Anzhen Hospital who were aged 80 years or older were enrolled. Results: Eight (3.2%) patients were diagnosed as single vessel coronary artery disease (CAD), 29 cases (11.5%) were diagnosed as bifurcation vessel CAD, and 215 cases (85.3%) were multivessel CAD. One hundred and one cases (40.1%) were diagnosed as left main artery disease, among which 51 cases (20.2%) had old myocardial infarction. Two hundred and forty-eight patients belonged to Canadian Cardiovascular Society (CCS) classⅠ-Ⅲ and 4 cases to CCS class Ⅳ. One hundred and forty-five cases belonged to New York Heart Association (NYHA) classⅠ-Ⅱ and 107 cases to NYHA class Ⅲ-Ⅳ. Mean graft number was 3. Two hundred and six patients (81.7%) received total vein graft operation. Intra-aortic balloon pump (IABP) was used in 43 patients (17.1%). In-hospital death occurred in 15 cases (6.0%). Major in-hospital complications included reoperation (16 cases), re-intubation (16 cases), dialysis (11 cases), sternum infection (2 cases), atrial fibrillation (63 cases). The follow-up time was from 1 to 11 years (with a mean time of 6 years). All-cause mortality was 18.1% (43 cases). The major out-of-hospital complications included recurrent myocardial infarction (3 cases), stroke (3 cases), re-admission (27 cases) and recurrent angina pectoris (20 cases). Conclusion: OPCABG is safe and effective for myocardial revascularization in patients aged 80 years and over.

Abstract
Hepatoblastoma is the most common liver tumor of early childhood, which is usually characterized by unusual hypervascularity. Recently, long non-coding RNAs (lncRNA) have emerged as gene regulators and prognostic markers in several cancers, including hepatoblastoma. We previously reveal that lnRNA-TUG1 is upregulated in hepatoblastoma specimens by microarray analysis. In this study, we aim to elucidate the biological and clinical significance of TUG1 upregulation in hepatoblastoma. We show that TUG1 is significantly upregulated in human hepatoblastoma specimens and metastatic hepatoblastoma cell lines. TUG1 knockdown inhibits tumor growth and angiogenesis in vivo, and decreases hepatoblastoma cell viability, proliferation, migration, and invasion in vitro. TUG1, miR-34a-5p, and VEGFA constitutes to a regulatory network, and participates in regulating hepatoblastoma cell function, tumor progression, and tumor angiogenesis. Overall, our findings indicate that TUG1 upregulation contributes to unusual hypervascularity of hepatoblastoma. TUG1 is a promising therapeutic target for aggressive, recurrent, or metastatic hepatoblastoma.

Abstract
AIMS 14,15-Epoxyeicosatrienoic acid (14,15-EET) is abundantly expressed in brain and exerts protective effects against ischaemia. 14,15-EET is hydrolysed by soluble epoxide hydrolase (sEH). sEH-/- mice show a higher level of 14,15-EET in the brain. Astrocytes play a pivotal role in neuronal survival under ischaemic conditions. However, it is unclear whether the neuroprotective effect of 14,15-EET is associated with astrocytes. METHODS A mouse model of focal cerebral ischaemia was induced by middle cerebral artery occlusion. Oxygen-glucose deprivation/reoxygenation (OGD/R) was performed on cultured murine astrocytes, neurons and a human cell line. Cell viabilities were measured by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H-tetrazolium bromide (MTT) assay. The mRNA expressions were quantified by real-time PCR. Brain derived neurotrophic factor (BDNF) concentration was measured by ELISA. Protein expressions were quantified by Western blotting. BDNF and peroxisome proliferators-activated receptor gamma (PPAR-γ) expressions were analysed by confocal microscopy. RESULTS Decreased infarct volumes, elevated BDNF expression and increased numbers of BDNF/GFAP Glial Fibrillary Acidic Protein double-positive cells were observed in the ischaemic penumbra of sEH-/- mice. The decreased infarct volumes of sEH-/- mice were diminished by intracerebroventricular injection of a blocker of BDNF receptor. 14,15-EET increases BDNF expression and cell viability of murine astrocytes and U251 cells by BDNF-TrkB Tyrosine receptor kinase-B-extracellular signal-regulated kinase 1/2 signalling during OGD/R. 14,15-EET protects neurons from OGD/R by stimulating the production of astrocyte-derived BDNF. 14,15-EET stimulates the production of astrocyte-derived BDNF through PPAR-γ/p-cAMP-response element binding protein signal pathways. CONCLUSIONS Our study demonstrates the importance of 14,15-EET-mediated production of astrocyte-derived BDNF for enhancing viability of astrocytes and protecting neurons from the ischaemic injury and provides insights into the mechanism by which 14,15-EET is involved in neuroprotection.

Abstract
BACKGROUND Few studies have explored the risk factors of sarcopenia in certain cohorts. The objective of this study was to examine the incidence of sarcopenia and associated factors over a 1-year period in an elderly Chinese suburban population. METHODS This study was conducted on 356 Chinese suburb-dwelling participants aged ≥60 years, for whom detailed information regarding sociodemographics, behavioral characteristics, and medical conditions had been documented. Sarcopenia was defined according to the Asian Working Group for Sarcopenia (AWGS) criteria. Sarcopenia incidence was documented after one year of follow-up, and correlated with several possible factors. RESULTS At baseline, 64 (9.7%) of the initial 657 participants had sarcopenia. The prevalence of sarcopenia was 10.4% after one year. Between baseline and 1-year follow-up, 13 of the participants without sarcopenia at baseline had developed sarcopenia. After multivariate adjustments, it was found that the incidence of sarcopenia increased with age and high body mass index (BMI) is associated with less incidence of sarcopenia. Incidence was also higher among women. CONCLUSIONS We found sarcopenia incidence increased with age, and women were more likely to have sarcopenia. A higher BMI is also associated with a lower incidence of sarcopenia. Maintaining a healthy weight could be beneficial in the prevention of sarcopenia.

Abstract
BACKGROUND The colon plays a key role in regulating the homeostasis of bile acids. AIM The present study aims to evaluate the influence of colon cancer towards the homeostasis of bile acids. METHODS The free and conjugated bile acids were determined using ultraperformance LC (UPLC) coupled with ABI 4000 QTRAP triple quadrupole instruments. RESULTS The results showed that the free bile acids in serum of patients with colon cancers tend to increase, and the conjugated bile acids tended to decrease, especially for taurolithocholate (TLCA) (p<0.001). CONCLUSION The alteration of bile acids balance in colon cancers indicated the possibility of complicated diseases due to the disrupted balance of bile acids.

Abstract
IL-17 and IL-22 are implicated in the pathogenesis of autoimmune diseases. The roles of IL-22 in the pathophysiology of myasthenia gravis (MG) remain unsettled. The aim of this study was to investigate the possible relationship between serum IL-22, IL-17 levels, anti-acetylcholine receptor antibody (anti-AChR Ab) titres and clinical parameters in patients with MG. The serum IL-22, IL-17 levels and anti-AChR Ab titres were tested by enzyme-linked immunosorbent assay (ELISA), while the expression of IL-22 and IL-17 mRNAs in peripheral blood mononuclear cells (PBMC) from healthy and MG subjects were detected by quantitative real-time PCR (qRT-PCR). Furthermore, PBMC from 12 patients with generalized MG were purified and treated with recombinant human IL-22 (rhIL-22), the IL-17 levels of supernatant were detected by ELISA. We found that the IL-17 levels were significantly increased, but IL-22 levels were significantly decreased in the serum of patients with MG compared with healthy controls. Consistantly, a significant decrease in IL-22 mRNA levels and an increase in IL-17 mRNA levels were detected in PBMC collected from patients with MG, compared with healthy controls. A negative correlation between IL-22 mRNA in PBMC, serum IL-22 and serum anti-AChR Ab levels was found in patients with MG. Moreover, in cultured MG PBMC treated with recombinant human IL-22 (rhIL-22), the IL-17 levels were decreased in a dose-dependent manner. Our findings indicated a possible role of IL-22 as a protective factor in MG.

Abstract
Daylily (Hemerocallis spp.) is an herbaceous, perennial plant, cultivated for its flowers. Daylily is sold in Asian markets as fresh or dried flowers (the flowers of some species, e.g., Hemerocallis citrina, are edible) or as the corm, which is used for medicinal purposes. In June 2011, daylily leaf streak was found in a nursery of Jilin Agricultural University, Jilin Province, China. Symptoms included water-soaked, irregular spots along the leaf midvein that turned orange to reddish brown and eventually enlarged to coalesce into extensive, necrotic streaks along the length of the leaf, as previously reported (2). Heavily infected leaves often withered and died. Four isolates were recovered from necrotic tissue of leaf spots and cultured on potato dextrose agar (PDA) at 25°C. All colonies were initially cream to peach colored and appeared slimy. With the maturation of the culture, the colonies became dark brown to black with sparse aerial hyphae. Blastic conidia formed simultaneously on intercalary or terminal, undifferentiated conidiogenous cells, and were scattered in dense sections on culture surface. When the conidia dropped from conidiogenous cell, an indistinct scar or a denticle remained. Conidia were hyaline, one-celled, smooth, ellipsoidal, and variable in size (2.73 to 6.01 × 8.45 to 19.36 μm), and all morphological characteristics were consistent with Kabatiella microsticta Bubak (syn. Aureobasidium microstictum; 2,4). The internal transcribed spacer (ITS) region of the nuclear rDNA was amplified using primers ITS4/ITS5 (1). ITS (534 bp) was identical among all four isolates (GenBank Accession No. HE798117) and 100% identical to that of K. microsticta CBS 114.64 (FJ150873). Pathogenicity was confirmed by spraying 20 seedlings of daylily, propagated in tissue-culture medium, with a conidial suspension (106 conidia/ml) of each isolate. A second set of 20 seedlings was sprayed with the same volume of sterile water as the noninoculated control treatment. Plants were grown in the greenhouse at 20 to 25°C and were covered with plastic bags to maintain humidity on the foliage for 72 h. After 5 days, the foliar symptoms described earlier for the field plants appeared on the leaves, whereas the control plants remained healthy. K. microsticta was reisolated from the leaf spots of all 20 inoculated plants. Leaf streak is the most destructive disease of daylily, and was previously reported in Japan and the United States (Illinois, Kentucky, Mississippi, Louisiana, Pennsylvania, Maryland, Virginia, Florida, North Carolina, and Georgia) (3). To our knowledge, this is the first report of the disease caused by K. microsticta in China. References: (1) D. E. L. Cooke et al. Mycol. Res. 101:667, 1997. (2) E. J. Hermanides-Nijhof. Stud.

Abstract
BACKGROUND Immunotherapy using autologous dendritic cell (DC) vaccination has not been systematically evaluated in osteosarcoma. We therefore conducted a phase I trial to assess feasibility, safety and tumour-specific immune responses in patients with relapsed disease. PATIENTS AND METHODS Of 13 recruited patients with relapsed osteosarcoma, 12 received 3 weekly vaccines of autologous DCs matured with autologous tumour lysate and keyhole limpet haemocyanin (KLH), to a maximum of 6 vaccinations. An additional 3 paediatric patients afflicted with other tumour types and with relapsed disease received vaccines generated with identical methodology. Immune responses were assessed using an ELISpot assay for the detection of interferon gamma, whilst interleukin-2 and granzyme B were additionally assessed in cases where interferon-γ responses were induced. RESULTS In total 61 vaccines, of homogeneous maturation phenotype and viability, were administered with no significant toxicity. Only in 2 out of 12 treated osteosarcoma cases was there an induction of specific T-cell immune response to the tumour, whilst a strong but non-specific immune response was induced in 1 further osteosarcoma patient. Immune response against KLH was induced in only 3 out of 12 osteosarcoma patients. In contrast, three additional non-osteosarcoma patients showed significant T-cell responses to vaccine. CONCLUSION We have shown the strategy of DC vaccination in relapsed osteosarcoma is safe and feasible. However, significant anti-tumour responses were induced in only 2 out of 12 vaccinated patients with no evidence of clinical benefit. Comparison of results with identically treated control patients suggests that osteosarcoma patients might be relatively insensitive to DC-based vaccine treatments.

Abstract
OBJECTIVES To develop and validate a disease-specific Quality of Life (QOL) measure for a specialized osteoarthritis (OA)-Kashin-Beck disease (KBD). METHODS The standard methodology used for developing QOL instruments was employed. In phase 1, initially a group of health care professionals (HCPs) and KBD patient defined the overall concept of KBDQOL. It was followed by generation of an item pool through literature review, in-depth interview of 20 KBD patients and eight KBD HCPs and four focus group discussions. In phase 2, 368 KBD patients were interviewed and the reinterview of 95 participants, 10-14 days later assessed the reproducibility of the KBDQOL instrument. RESULTS A 37 items draft instrument was devised during phase 1. Principal Component Analysis (PCA) revealed six domains: physical function, activity limitation, social support, economics, mental health, and general health. Cronbach's alphas of six domains ranged from 0.77 to 0.90. The test-retest reliability (intraclass co-relation coefficient) of six domains was satisfactory, and ranged from 0.73 to 0.90. The smallest detectable change ranged from 13.2 to 30.2 points at the individual level and from 1.4 to 3.1 points at the group level for different domains. The construct validity was adequate when co-related with the EQ-5D (spearman co-relation coefficients: 0.49-0.61) and WHOQOL-BREF (spearman co-relation coefficients: 0.53-0.68). This resulted into the final version of KBDQOL instrument having 28 items and six domains. CONCLUSIONS The KBDQOL is a simple and easy to use 28-item six dimensional questionnaire. The measure has been developed as a true patient-based questionnaire and demonstrates good measurement properties.

Abstract
OBJECTIVE: The slit homologue 2 ( SLIT2) gene is a tumour suppressor gene. This study investigated the methylation status of the SLIT2 promoter in women with ovarian cancer in terms of identifying whether this might aid the early diagnosis of ovarian cancer. METHODS: Using methylation-specific polymerase chain reaction analysis, the methylation status of the SLIT2 promoter was measured in tumour tissue and serum samples from 36 patients with ovarian cancer and in matched serum samples from 25 controls without cancer. RESULTS: Aberrant methylation of the SLIT2 promoter was present in ovarian tissue from 29/36 (80.6%) ovarian cancer patients, but not in the 25 healthy controls. Among the cases with hypermethylation in their ovarian tissue, 27/29 (93.1%) of the case-matched serum DNA samples, including all four cases of early-stage ovarian cancer, showed hypermethylation of the SLIT2 promoter. CONCLUSIONS: Hypermethylation of the SLIT2 promoter may be a relatively early event in ovarian cancer; thus, its detection may be an effective approach to improve early diagnosis.

Abstract
Pachysandra (Pachysandra terminalis, Buxaceae) and Japanese Pachysandra, also called Japanese Spurge, is a woody ornamental groundcover plant distributed mostly in Zhejiang, Guizhou, Henan, Hubei, Sichuan, Shanxi, and Gansu provinces in China. In April 2010, P. terminalis asymptomatic plants were shipped from Beijing Botanical Garden Institute of Botany Chinese Academy of Science to the garden nursery of Jilin Agricultural University (43°48'N, 125°23'E), Jilin Province. In June 2011, Volutella blight (sometimes called leaf blight and stem canker) of P. terminalis was observed on these plants. Infected leaves showed circular or irregular, tan-to-brown spots often with concentric rings and dark margins. The spots eventually grew and coalesced until the entire leaf died. Cankers appeared as greenish brown and water-soaked diseased areas, subsequently turning brown or black, and shriveled and often girdled the stems and stolons. During wet, humid weather in autumn, reddish orange, cushion-like fruiting structures of the fungus appeared on the stem cankers and undersides of leaf spots. Symptoms of the disease were consistent with previous descriptions (2-4). Five isolates were obtained from necrotic tissue of leaf spots and cankers of stems and stolons and cultured on potato dextrose agar. The colony surface was salmon colored and slimy. Conidia were hyaline, one celled, spindle shaped, and 12.57 to 22.23 × 3.33 to 4.15 μm with rounded ends. Morphological characteristics of the fungus were consistent with the description by Dodge (2), and the fungus was identified as Volutella pachysandricola (telemorph Pseudonectria pachysandricola). The internal transcribed spacer (ITS) regions of the nuclear rDNA were amplified using primers ITS4/ITS5 (1). The ITS sequences were 553 bp long and identical among these five isolates (GenBank Accession No. HE612114). They were 100% identical to Pseudonectria pachysandricola voucher KUS-F25663 (Accession No. JN797821) and 99% identical to P. pachysandricola culture-collection DAOM (Accession No. HQ897807). Pathogenicity was confirmed by spraying leaves of clonally propagated cuttings of P. terminalis with a conidial suspension (1 × 106 conidia/ml) of the isolated V. pachysandricola. Control leaves were sprayed with sterile water. Plants were covered with plastic bags and kept in a greenhouse at 20 to 25°C for 72 h. After 5 to 8 days, typical disease symptoms appeared on leaves, while the control plants remained healthy. V. pachysandricola was reisolated from the leaf spots of inoculated plants. Pachysandra leaf blight and stem canker also called Volutella blight, is the most destructive disease of P. terminalis and previously reported in the northern humid areas of the United States (Illinois, Connecticut, Ohio, Indiana, Iowa, Massachusetts, Missouri, Kentucky, and Wisconsin), northern Europe (Britain, Germany, and Poland), and the Czech Republic. To our knowledge, this is the first report of the disease caused by V. pachysandricola in China. The disease may become a more significant problem in P. terminalis cultivation areas if the disease spreads on P. terminalis in nursery beds. References: (1) D. E. L. Cooke et al. Mycol.

Abstract
We propose an operational degree of polarization in terms of the variance of the Stokes vector minimized over all the directions of the Poincaré sphere. We examine the properties of this second-order definition and carry out its experimental determination. Quantum states with the same standard (first-order) degree of polarization are correctly discriminated by this new measure. We argue that a comprehensive quantum characterization of polarization properties requires a whole hierarchy of higher-order degrees.

Abstract
BACKGROUND AND OBJECTIVE Bone morphogenetic protein-7 (BMP-7) and insulin-like growth factor-1 (IGF-1) are important in periodontal reconstruction. However, their synergistic effect in periodontal regeneration by gene delivery has not been reported. In this study, gene delivery of these two growth factors to human periodontal ligament cells (hPDLCs) was examined for its effects on cell proliferation and differentiation. MATERIAL AND METHODS Recombinant adenoviruses containing both human BMP-7 and IGF-1 cDNA created by introducing the internal ribosome entry site (IRES) sequence were used to transfer the genes into hPDLCs. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and cell cycle analysis were used to observe their effects on cell proliferation, while alkaline phosphatase activity measurement, RT-PCR and in vivo tests were conducted to investigate their effects on cell differentiation. RESULTS The proliferation of hPDLCs transduced by adenoviruses coexpressing BMP-7 and IGF-1 was suppressed while their differentiation ability was enhanced. There was a synergism of BMP-7 and IGF-1 in up-regulating alkaline phosphatase activity and mRNA levels of collagen type I and Runx2. Implantation in vivo with scaffolds illustrated that the transduced cells exhibited osteogenic differentiation and formed bone-like structures. CONCLUSION The combined delivery of BMP-7 and IGF-1 genes using an IRES-based strategy synergistically enhanced differentiation of hPDLCs. It is suggested that this could be a new potential method in gene therapy for periodontal reconstruction.

Abstract
This study investigated selenoprotein P expression, using immunohistochemistry, in gastric adenocarcinoma tissue microarrays constructed from 30 gastric adenocarcinoma specimens and 30 normal gastric tissues (controls). Selenoprotein P expression scores were significantly lower in gastric adenocarcinoma (17/30, 56.7%) than in control tissues (25/30, 83.3%). Selenoprotein P was significantly more likely to be expressed in well-to-moderately differentiated cases (13/17, 76.5%) than in cases with low differentiation (4/13, 30.8%) and there was no significant difference in selenoprotein P expression between tumour node metastasis (TNM) stage I – II (11/19, 57.9%) and TNM stage III (6/11, 54.5%). In conclusion, selenoprotein P expression was low in gastric adenocarcinoma tissues compared with control tissues and was related to the degree of gastric adenocarcinoma differentiation but not to TNM stage.
