Abstract
BACKGROUND Pseudoachalasia is a rare disease that behaves similarly to achalasia (AC), making it sometimes difficult to differentiate. CASE PRESENTATION We report a case of 49-year-old male with adenocarcinoma of the gastroesophageal junction misdiagnosed as achalasia. No obvious abnormalities were found in his initial examinations including upper digestive endoscopy, upper gastrointestinal imaging and chest computed tomography (CT). During the subsequent introduced-peroral endoscopic myotomy (POEM), it was found that the mucosal layer and the muscular layer had severe adhesion, which did not receive much attention, delayed the clear diagnosis and effect treatment, and ultimately led to a poor prognosis for the patient. CONCLUSIONS This case suggests that when patients with AC found mucosal and muscular adhesions during POEM surgery, the possibility should be considered that the lesion may be caused by a malignant lesion.

Abstract
OBJECTIVES For resectable esophageal cancer, the choice of total minimally invasive esophagectomy (TMIE) or hybrid minimally invasive esophagectomy (HMIE) remains controversial. The purpose of this study was to evaluate the short-term clinical outcomes of TMIE and HMIE under the Ivor-Lewis procedure. METHODS The data of 145 patients diagnosed with middle or lower esophageal cancer who underwent radical Ivor-Lewis esophagectomy in the Affiliated Hospital of Qingdao University between January 2018 and December 2019 were retrospectively analyzed. The short-term outcomes such as complications during surgery or within 30 days after surgery and postoperative pain were analyzed. RESULTS All patients were divided into TMIE group (75 patients) and HMIE group (70 patients). No significant difference was observed in the baseline characteristics of the two groups. TMIE was associated with less blood loss than the HMIE group (p < 0.05). A total of 54 (37.2%) patients had postoperative complications. Although the two groups were statistically similar in the incidence of major complications, patients in the HMIE group were more likely to have pneumonia compared with those in the TMIE group. The numeric rating scale for pain was significantly higher in the HMIE group (p = 0.002) and more patients required an additional opioid analgesia after esophagectomy (p = 0.282). CONCLUSIONS In conclusion, according to perioperative outcomes, TMIE can benefit patients better than HMIE.

Abstract
The prognosis for pathologically node-negative (pN0) esophageal squamous cell carcinoma (ESCC) with surgery alone remains poor. We aimed to develop a model for a more precise prediction of recurrence, which will allow personalized management for pN0 ESCC after upfront complete resection. Clinical and pathological records of patients with completely resected pT1-3N0M0 ESCC were retrospectively analyzed between January 2014 and December 2019. A nomogram for the prediction of recurrence was established based on the Cox regression analysis and evaluated by C-index, AUC, and calibration curves. The model was further validated using bootstrap resampling and k-fold cross-validation and compared with the 8th edition of the AJCC TNM staging system using Td-ROC, NRI, IDI, and DCA. Two-hundred-and seventy cases were included in this study. The median follow-up was 45 months. Distant and/or loco-regional recurrences were noted in 89 (33.0%) patients. The predictive model revealed pT-category, differentiation, perineural invasion, examined lymph nodes (ELN), and prognostic nutritional index (PNI) as independent risk factors for recurrence, with a c-index of 0.725 in the bootstrapping cohort. Td-ROC, NRI, and IDI showed a better predictive ability than the AJCC 8th TNM staging system. Based on this model, patients in the low-risk group had a significantly lower recurrence incidence than those in the high-risk group (p < .001). The predictive model developed in this study may facilitate the precise prediction of recurrences for pN0 ESCC after upfront surgery. Stratifying management of those patients might bring significantly better survival benefits.

Abstract
Objective: To study the intestinal flora specific differences with different lesional stages of metabolic (disorder) associated fatty liver disease (MAFLD), namely simple steatosis and steatohepatitis, so as to provide a new direction for MAFLD-related intestinal flora transplantation and targeted therapy. Methods: Mice were fed with normal diet, methionine-choline deficient diet (MCD) and a high-fat high-fructose diet (HFHF) for 12 weeks to construct simple steatosis and steatohepatitis models. HE and Sirius scarlet staining was performed to observe the liver pathological changes. The qPCR method was used to evaluate inflammation and liver fibrosis factors. A fully automatic biochemical analyzer was used to detect changes in liver transaminase and blood lipids. 16S rRNA sequencing method was used to observe the intestinal flora differences in the feces of each group of mice. The comparison of means between two groups was performed by t-test, and the comparison of means between multiple groups was performed by one-way analysis of variance. Kruskal-Wallis rank sum test was used for non-normally distributed data. Results: NAFLD scores were determined with pathological sections (HE and Sirius scarlet staining) of mice liver, which showed that the inflammation and liver fibrosis scores of the MCD and HFHF groups were 2.12 ± 0.18 and 1.06 ± 0.24, and 2.22 ± 0.16 and 0.46 ± 0.10, respectively. The degree of liver inflammation and fibrosis was significantly higher in the MCD than the HFHF group (P < 0.001 and P < 0.01). Lipid deposition was higher in the HFHF than the MCD group (P < 0.001), and the scores were 2.36 ± 0.17 and 1.60 ± 0.24 respectively. Simultaneously, the inflammatory [tumor necrosis factor-A (TNF-a), chemokine factor-2 (CXCL-2)] and hepatic fibrosis indicators [vascular smooth muscle actin alpha (a-SMA) and connective tissue growth factor (CTGF)] had confirmed the above-mentioned results at the transcription level. Moreover, the intestinal flora diversity was reduced (P < 0.05) in the MCD group than the HFHF group, and the Simpson and Shannon index were 0.31 ± 0.10 and 0.42 ± 0.05, and 2.03 ± 0.33 and 1.70 ± 0.28, respectively, and the differences were significant between different intestinal flora groups. The levels of Desulfovibrio, Odoribacter, and Roseburia flora were significantly increased in the HFHF than the MCD group, and the levels of Faecalibaculum, Parasutterella, Alipis, Butyricimonas_virosa, Turicibacter_sp, and Romboutsia_ilealis were significantly increased in the MCD than the HFHF group, and the difference was statistically significant (P < 0.05). Conclusion: There are significant differences in intestinal flora diversity between simple steatosis and steatohepatitis models. Therefore, clarifying the difference between the two may provide a new direction for the stage manner treatment of MAFLD.

Abstract
The ADJUVANT study reported the comparative superiority of adjuvant gefitinib over chemotherapy in disease-free survival of resected EGFR-mutant stage II–IIIA non-small cell lung cancer (NSCLC). However, not all patients experienced favorable clinical outcomes with tyrosine kinase inhibitors (TKI), raising the necessity for further biomarker assessment. In this work, by comprehensive genomic profiling of 171 tumor tissues from the ADJUVANT trial, five predictive biomarkers are identified (TP53 exon4/5 mutations, RB1 alterations, and copy number gains of NKX2-1, CDK4, and MYC). Then we integrate them into the Multiple-gene INdex to Evaluate the Relative benefit of Various Adjuvant therapies (MINERVA) score, which categorizes patients into three subgroups with relative disease-free survival and overall survival benefits from either adjuvant gefitinib or chemotherapy (Highly TKI-Preferable, TKI-Preferable, and Chemotherapy-Preferable groups). This study demonstrates that predictive genomic signatures could potentially stratify resected EGFR-mutant NSCLC patients and provide precise guidance towards future personalized adjuvant therapy. Adjuvant gefitinib improves outcomes in non-small cell lung cancer (NSCLC) patients compared to chemotherapy, but not in all cases. Here, the authors find genomic biomarkers of response to gefitinib in NSCLC patients from the ADJUVANT trial, and propose a score to stratify them by potential benefit from the treatment.

Abstract
OBJECTIVES To understand the sequelae of COVID-19. METHODS We followed up 1174 patients with severe coronavirus disease 2019 (COVID-19)who were recovered and discharged for 6 months. RESULTS There were 175 cases with clear IgG results 6 months after discharge, of which 82 (46.9%) were IgG (+) and 16 (9.1%) were IgG (dim+). Four hundred and forty-one participants (55.4%) had some kind of sequelae. The most common symptoms were fatigue (25.3%), sleep disorder (23.2%) and shortness of breath (20.4%). In those who had sequelae, 262 (59.4%) had more than one symptom. Critical cases were more likely to have cough (20.5% vs 11.6%, p = 0.023) and hypomnesis (15.1% vs 8.0%, p = 0.041) than severe cases. Furthermore, univariate and multivariate logistic regression analyses revealed that women are more likely to have multiple symptoms (p = 0.002), fatigue (p = 0.009) and sleep disorder (p = 0.008), whereas critical illness was found as independent risk factor for hypomnesis (p = 0.045). CONCLUSION Our study demonstrated the duration of antibody and sequelae of COVID-19 and compared the differences amongst different populations.

Abstract
Background This study aimed to identify variables associated with anastomotic leakage after esophagectomy and established a tool for anastomotic leakage prediction. Methods Twenty-six preoperative and postoperative variables were retrospectively collected from esophageal cancer patients who were treated with radical esophagectomy from January 2018 to June 2020 in the Affiliated Hospital of Qingdao University. SPSS Version 23.0 and Empower Stats software were used for establishing a nomogram after screening relevant variables by univariate and multivariate Logistic regression analyses. The established nomogram was identified by depicting the receiver operating characteristic (ROC) curves and calibration curve, which was verified by 1,000 bootstrap resamples method. Results A total of 604 eligible esophageal cancer patients were included, of which 51 (8.4%) patients had anastomotic leakage. Multivariate Logistic regression analysis showed that smoking, anastomotic location, anastomotic technique, prognostic nutritional index (PNI) and ASA score were independent risks of anastomotic leakage. The area under curve (AUC) of ROC in the established nomogram was 0.764 (95% CI, 0.69–0.83). The internal validation confirmed that the nomogram had a great discrimination ability (AUC =0.766). Depicted calibration curve demonstrated a well-fitted prediction and observation probability. In addition, the decision curve analysis concluded that the newly established nomogram is significant for clinical decision-making. Conclusions This nomogram provided the individual prediction of anastomotic leakage for esophageal cancer patients after surgery, which might benefit treatment results for patients and clinicians, as well as pre-and postoperative intervention strategy-making.

Abstract
Locally advanced thymic tumor usually invades adjacent great vessels, while the optimal treatment strategy for vessels resection and prosthetic replacement is still in controversial. We hereby present our series of patients undergoing autologous pericardial angioplasty for thymic malignancies. For invasive thymic tumors involving the superior vena cava (SVC), the replacement vessel was prepared by autologous pericardium and placed between the right atrium and distal left innominate vein stump to establish a SVC bypass. Then, the distal right innominate vein and proximal SVC were blocked, and the thymic tumor and involved vessel were completely resected, followed by SVC reconstruction using pericardium. We retrospectively analyzed the clinical characteristics and short-term outcomes of six related patients with autologous pericardial angioplasty. Due to the homologous advantages of autologous pericardial transplantation, those patients didn't need to receive anticoagulant therapy during the perioperative period, so as to avoid the occurrence of hemorrhage, embolism and other graft-related complications. There were no postoperative long-term thoracic drainage (>7 days), anastomotic bleeding, reconstructed vascular stenosis, embolism or even secondary thoracotomy and other related complications occurred in this case series. The application of autologous pericardium for the replacement of mediastinal great vessels in the surgery of locally advanced thymoma is a safe and effective technique. Compared with former artificial materials, such as polytetrafluoroethylene synthetic prosthesis, autologous pericardial transplantation avoids the occurrence of high risk graft-related complications such as postoperative hemorrhage and vascular stenosis, and its clinical application prospect is worth expecting.

Abstract
ADJUVANT-CTONG1104 (ClinicalTrials.gov identifier: NCT01405079), a randomized phase III trial, showed that adjuvant gefitinib treatment significantly improved disease-free survival (DFS) versus vinorelbine plus cisplatin (VP) in patients with epidermal growth factor receptor (EGFR) mutation-positive resected stage II-IIIA (N1-N2) non–small-cell lung cancer (NSCLC). Here, we report the final overall survival (OS) results.

Abstract
Background This study investigated the prognostic impact of (neo‐)adjuvant radiation therapies in early stage esophageal cancer. Methods A retrospective analysis using the Surveillance, Epidemiology, and End Results (SEER) database was conducted from 2004 to 2016. Patients with pathologically staged T1‐4N0M0 esophageal cancer were divided into two treatment groups: (i) neoadjuvant radiotherapy followed by surgery; and (ii) upfront esophagectomy followed by adjuvant radiotherapy. Propensity scored match and Cox proportional hazards model were used to identify covariates associated with overall survival and cancer‐specific survival. Results There were 821 patients selected, of whom 588 (71.6%) received neoadjuvant radiotherapy and 233 (28.4%) received adjuvant radiotherapy. For the entire cohort, neoadjuvant radiotherapy was associated with a significantly benefit in five‐year survival outcomes compared with adjuvant radiotherapy (P < 0.01). After matching, the survival outcomes were still better for neoadjuvant radiotherapy than that of adjuvant treatment. Stratifying based on pathologic tumor status, neoadjuvant radiation was associated with improved CSS (five‐year survival 73.7% vs. 42.1%; P = 0.014) for localized (pT3‐4N0) disease. The Cox multivariate regression analysis revealed that the addition of neoadjuvant radiation for pT3‐4N0 diseases with tumor length ≥ 5 cm and squamous cell carcinoma, was a powerful prognostic factor for improved cancer‐specific survival (P < 0.01). Conclusions Compared with adjuvant radiotherapy, the addition of neoadjuvant radiation for pT3‐4N0 diseases has been associated with improved cancer‐specific survival in high‐risk patients. Studies on preoperative neoadjuvant therapies would be plausible in high‐risk esophageal cancer patients.

Abstract
Background The impact of neoadjuvant chemoradiotherapy (nCRT) on early stage esophageal cancer is unknown. Here, we compared the outcomes after esophagectomy alone or nCRT plus surgery for clinically staged node‐negative esophageal cancer. Methods We searched the Surveillance, Epidemiology, and End Results database for patients with clinically node‐negative (cN0) esophageal cancer from 2004 to 2016 who underwent surgery alone or nCRT plus surgery. Propensity score matching and Cox regression analysis were used to identify covariates associated with overall survival and cancer‐specific survival. Results A total of 1587 patients were retrospectively identified, of whom 49.8% (n = 791) received nCRT and 80.2% (n = 1273) were truly node‐negative diseases. For the entire cohort, surgery alone was associated with a statistically significant but modest absolute increase in survival outcomes (P < 0.01). After matching, nCRT was associated with improved five‐year overall survival for pT3‐4N0 (localized) disease (59.6% vs. 37.7%; P < 0.001) and pathological node‐positive disease (60.5% vs. 40.7%; P = 0.002). Cox multivariate regression analysis revealed that the addition of nCRT for truly node‐negative patients with tumor length ≥ 3 cm, pT1‐2N0 (early‐staged) and localized disease were independent risk factors for survival than surgery alone (P < 0.01). Conclusions Compared with surgery alone, patients with cN0 esophageal cancer with pathological node‐positive or localized true node‐negative disease gain a significant survival benefit from nCRT. However, nCRT plus surgery was associated with decreased survival for early‐staged true node‐negative patients. This finding may have significant implications on the use of neoadjuvant chemoradiation in patients with cN0 disease.

Abstract
Background The purpose of this study was to analyze the clinical characteristics and prognostic survival of patients with neuroendocrine tumors of the thymus (NETTs), and to develop and validate a nomogram model for predicting the prognosis of patients. Methods We conducted a retrospective analysis of patients with neuroendocrine tumors of the thymus in the Surveillance, Epidemiology, and End Results (SEER) database in the United States between 1988 and 2016. Cox scale risk regression analysis, the Kaplan‐Meier method and log‐rank test were used to carry out the significance test to determine the independent prognostic factors, from which a nomogram for NETTs was established. C‐index and calibration curve were used to evaluate the prediction accuracy of the model. External validation of the nomogram was performed using data from our center. Results A total of 254 patients with NETTs were collected in the SEER database. In the multivariable analysis, T stage, tumor grade, surgery, and chemotherapy were found to be independent factors affecting the prognosis of patients (all P < 0.05). A nomogram model was constructed based on these variables, and its c‐index was 0.707 (0.661–0.752). The c‐index results showed that the nomogram model had better authentication capability than the eighth edition of the tumor, node, metastasis (TNM) staging system and Masaoka‐Koga (MK) staging system. The calibration curve showed that the model could accurately predict patient prognosis. Conclusions The study established a nomogram model that predicted the overall survival rate of one‐, three‐ and five‐years, and used the survival prediction model to optimize individualized therapy and prognostic follow‐up through risk stratification.

Abstract
Objective: To compare the short-term and long-term results of thoracoscopic and open pneumonectomy for non-small cell lung cancer. Methods: The clinical data of patients with non-small cell lung cancer who underwent pneumonectomy in the Department of Thoracic Surgery, Qingdao University Hospital from January 2008 to December 2016 were collected. Totally 142 patients (55 in the thoracoscopic group and 87 in the open group) were included in the study. A total of 29 pairs of patients were successfully matched by propensity score matching (PSM). Perioperative outcomes and overall survival were compared between the two groups using t test, χ(2) test, Kaplan-Meier curve and Log-rank test, respectively. Results: Camparion with open group, the thoracoscopic group had longer operative time ((209.7±70.2) minutes vs. (171.3±43.5) minutes, t=2.50, P=0.02), more mediastinal lymph node dissection (M(Q(R)): 17(9) vs. 11(10), W=388, P=0.02) and shorter postoperative hospital stay (7.0(3.5) vs. 9.0(3.0), W=285, P=0.03). There was no significant difference in estimated blood loss, postoperative drainage time, dissected lymph node number, dissected lymph node station and perioperative complications. After PSM, there were no signifificant differences found in 3-year survival (71.4% vs. 48.1%, P=0.10) and 3-year disease-free survival (67.4% vs. 47.2%, P=0.13) between the two groups. Conclusion: Thoracoscopic pneumonectomy is safe and feasible for the treatment of non-small cell lung cancer with more mediastinal lymph node dissection and accelerating recovery, and equivalent long-term prognosis when compared with open approach.

Abstract
BACKGROUND The impact of adjuvant treatment for esophageal carcinoma with tumor-negative lymph nodes after upfront radical esophagectomy is still uncertain. This study investigated the effects of postoperative radiotherapy in pT1-3N0 esophageal carcinoma after radical resection. METHOD We retrospectively identified pT1-3N0M0 esophageal carcinoma patients between 2000 and 2016 from the Surveillance, Epidemiology, and End Results database. Patients with upfront esophagectomy were categorized as having received surgery alone (SA) and surgical resection followed by adjuvant radiotherapy (SA + RT). Propensity score matching, univariate and multivariate analysis were performed to compare overall survival (OS) and cause-specific survival (CSS). RESULTS A total of 2862 patients were identified, of whom 274 received SA + RT and 2588 received SA. The median follow-up was 60.4 months (95%CI, 58.7-62.1 months). The five-year OS and CSS were better for SA group compared with SA + RT group (P < 0.001, respectively). Furthermore, after matching, the OS and CSS were still significantly better for SA patients. For T subgroup analysis, postoperative radiotherapy was an independent prognostic factor only for pT1 patients with worse OS, without survival differences for pT2 and pT3 patients. However, after multivariate cox analysis, postoperative radiotherapy can provide significantly better OS for pT3 patients with tumor length ≥5 cm (P = 0.03; 95%CI, 0.29-0.94). CONCLUSIONS Among pT1-3N0M0 esophageal carcinoma patients, postoperative radiotherapy can provide significantly better OS for pT3 patients with tumor length ≥5 cm. However, there are no survival benefits for pT1-2 patients after SA + RT procedure. This finding may have significant implications on the use of adjuvant radiation in patients with pN0 disease.

Abstract
Tracheal diverticulum is a rarely congenital or acquired tracheal benign entity, characterized by round or spherical out-pouching of the tracheal wall. Most of the tracheal diverticula are asymptomatic disease, and therefore surgical treatment has not been widely reported. Symptomatic diverticula can accept conservative treatment such as anti-inflammatory, postural drainage, etc. Transcervical resection or endoscopic laser surgery or electrosurgery should be considered for patients with severe symptoms or combined with repeated tracheobronchial inflammation. However, there is still insufficient evidence to recommend the optimal therapeutic schedule at present. We describe a special tension tracheal diverticulum with rare symptoms of dysphagia and dizziness for the first time which has a recurrence after interventional sclerotherapy followed by transcervical resection.

Abstract
BACKGROUND Tumor IL17-producing (IL17A+) cells infiltration has different prognostic values among various cancers. The objective of this study was to assess the effect of IL17A+ cells in gastric cancer. PATIENTS AND METHODS The study included two patient cohorts, the Cancer Genome Atlas cohort (TCGA, n = 351) and the Zhongshan Hospital cohort (ZSHC, n = 458). The TCGA and ZSHC were used for mRNA-related and cells infiltration-related analyses, respectively. The roles of IL17A mRNA and IL17A+ cells in overall survival (OS), response to adjuvant chemotherapy (ACT), and immune contexture were evaluated. Another independent cohort was included to identify the correlation between mRNA of IL17A and IL17A+ cells infiltration (the preliminary Zhongshan Hospital cohort, PZSHC, n = 21). RESULTS The infiltration of IL17A+ cells was positively correlated with the expression of IL17A mRNA (Spearman's ρ = 0.811; P < 0.001). High IL17A mRNA expression and intratumoral IL17A+ cells were correlated with improved OS and remained to be significant after adjusted for confounders. Patients with TNM II/III disease whose tumor present higher intratumoral IL17A+ cells or lower peritumoral IL17A+ cells can benefit more from ACT. Elevated IL17A mRNA expression and increased intratumoral IL17A+ cells infiltration was associated with more antitumor mast cells and nature killer cells infiltration and less pro-tumor M2 macrophages infiltration. High IL17A mRNA expression represented a Th17 cells signature and immune response process and was correlated with increased cytotoxic GZMA, GZMB, IFNG, PRF1, and TNFSF11 expression. CONCLUSIONS IL17A mRNA expression and intratumoral IL17A+ cells infiltration were correlated with antitumor immune contexture. IL17A+ cells infiltration could be used as an independent prognostic biomarker for OS and predictive biomarker for superior response to ACT, and further prospective validation needs to be conducted.

Abstract
Objective: To evaluate the safety and efficacy of patients with centrally located lung cancer in sleeve lobectomy by video-assisted thoracic surgery (VATS). Methods: A retrospective analysis was performed on consecutive patients with centrally located lung cancer who underwent sleeve lobectomy admitted in the Affiliated Hospital of Qingdao University from January 2010 to September 2014. Propensity score matching analysis was performed to compare patients for thoracoscopic surgery and open surgery. Twenty-one pairs (42 cases) patients were included for analysis. The t-test, χ(2) test or Fisher's exact probabilities was adopted, if appropriate, to compare demographics and outcomes between the 2 groups. The Kaplan-Meier method and the Log-rank test were used for the distributions of disease free survival (DFS) and overall survival (OS) and their comparisons. Results: After propensity score-matched analysis, the VATS group had a longer operative time ((296.9±73.6) minutes vs. (218.1±59.2) minutes, t=3.82, P=0.00), but shorter postoperative drainage time ((3.3±1.5) days vs. (2.0±3.0) days, t=-0.93, P=0.01) and hospitalization time((6.7±2.8) days vs. (12.1±8.7)days, t=-1.72, P=0.01) than that of the thoracotomy group. Perioperative complications, 1-year and 3-year disease-free and overall survival rates were not statistically different between the two groups. Conclusion: For suitable patients, sleeve lobectomy by VATS is an acceptable safe and effective surgical procedure for patients with central lung cancer.

Abstract
Objective: To investigate the effect and related mechanism of homocysteine (Hcy) on calcium overload in neonatal rat atrial cells (NRICs). Methods: NRICs were assigned to 9 groups after culture for 3 days: (1) control group; (2) Hcy group (0, 50, 100, 200, 500 μmol/L for 48 hours); (3) antioxidant group (NAC, 10 μmol/L for 24 hours); (4) Hcy+NAC group (500 μmol/L Hcy for 48 hours, then treated with 10 μmol/L NAC for 24 hours); (5) calcium/calmodulin dependent protein kinase Ⅱδ (CaMKⅡδ) inhibitor group (KN-93, 3 μmol/L KN-93 for 5 hours); (6) specific sodium current inhibitor group (ELE, 1 μmol/L ELE for 5 hours); (7) Hcy+KN-93 group (500 μmol/L Hcy for 48 hours, then treated with 3 μmol/L KN-93 for 5 hours); (8) Hcy+ELE group (500 μmol/L Hcy for 48 hours, then treated with 1 μmol/L ELE for 5 hours; (9) Hcy+KN-93+ELE group (500 μmol/L Hcy for 48 hours, then treated with 3 μmol/L KN-93 and 1 μmol/L ELE for 5 hours). Moreover, NRICs were also treated with CaMKⅡδ-siRNA lentivirus, and Nav1.5-siRNA lentivirus, negative lentivirus carrier containing green fluorescent protein (GFP) for 24 hours. The MOI values of the three groups were 10. Infection efficiency of lentivirus was determined by observing the percentage of GFP fluorescence under inverted fluorescence microscope after transfection for 24 hours, and cultured regularly with simultaneous Puro screening, then cells were grouped as Hcy+CaMKⅡδ-siRNA group, Hcy+Nav1.5-siRNA group and Hcy+negative group. The concentration of Ca(2+) in NRICs ([Ca(2+)]i) of various groups was detected through Fluo-4/AM fluorescence probe, then 2', 7'- two chlorofluorescein diacetate (DCFH-DA) was used as a probe to detect reactive oxygen species (ROS) in NRICs by flow cytometry. The malondialdehyde (MDA) was detected by the activity of superoxide dismutase (SOD) and xanthine oxidase was detected by thiobarbituric acid colorimetry. The protein and mRNA expression level of CaMKⅡδ and Nav1.5 in NRICs were detected by Western blot and quantitative real-time PCR. Results: (1) ROS, MDA and SOD were similar between NAC group and control group, ROS and MDA were significantly increased, while SOD was significantly reduced in Hcy group in a concentration-dependent manner. (2) [Ca(2+)]i: The level of [Ca(2+)]i was (155.57+7.25), (187.43+13.07), (248.98+27.22) and (307.36+15.09) nmol/L in 50, 100, 200 and 500 μmol/L Hcy groups, which was significantly higher than that in the control group ((123.18+7.24) nmol/L, P<0.01). In addition, the level of [Ca(2+)]i in Hcy+NAC group ((222.87+23.71)nmol/L) was significantly lower than that in Hcy 500 μmol/L group ((305.15+39.45) nmol/L, P<0.05), while [Ca(2+)]i level was similar between NAC group and the control group. (3) The protein expression of CaMKⅡδ and Nav1.5 was significantly upregulated in Hcy groups than in the control group. The protein expression level of CaMKⅡδ-Thr287 was significantly lower in NAC group than in Hcy 500 μmol/L group (P<0.01), however, there was no significant difference on the protein expression levels of CaMKⅡδ-Thr287 and Nav1.5 between NAC group and control group (all P>0.05). (4) The protein expression levels of CaMKⅡδ-Thr287 and the concentration of [Ca(2+)]i were significantly lower in Hcy+KN-93 group and Hcy+KN-93+ELE group than in Hcy 500 μmol/L group (P<0.05). [Ca(2+)]i concentration was significantly lower in Hcy+KN-93 group, Hcy+ELE group and KN-93+ELE+Hcy group than in Hcy 500 μmol/L group (P<0.05). (5) The mRNA and protein expression levels of CaMKⅡδ and Nav1.5 in each group infected with lentivirus: the GFP expression was ideal post lentivirus transfection for 24 hours (up to 90%), which was significantly lower in the CaMKⅡδ-siRNA group and Nav1.5-siRNA group than in the negative infection group (all P<0.05), which was similar between negative infection group and control group (P>0.05). Moreover, the mRNA and protein expression levels of CaMKⅡδ and CaMKⅡδ-Thr287 was significantly lower in Hcy+Nav1.5-siRNA group than in Hcy+negative infection group (P<0.05). The protein and mRNA levels of Nav1.5 were similar between Hcy+CaMKⅡδ-siRNA group and Hcy+negative infection group (P>0.05). Conclusions: Hcy can induce calcium overload in NRICs by increasing oxidative stress, upregulating the sodium channel protein, and activating the late sodium current and phosphorylating CaMKⅡδ.

Abstract
Progeny performances, variations and combining abilities for growth traits were evaluated in a factorial mating design of Eucommia ulmoides. Three marker systems, sequence-related amplified polymorphism, amplified fragment length polymorphism, and inter-simple sequence repeat, were used to determine genetic distances between parents. Correlations of genetic distances with progeny performances, within-family coefficients of variation and specific-combining abilities were established for height and basal diameter traits. Significant positive correlations were found between progeny performances of growth traits and genetic distances of parents based on sequence-related amplified polymorphism markers or a combination of all 3 marker systems. This revealed that crosses between genetically distant parents produced progenies with excellent growth performances. The lack of correlations between parental genetic distances and within-family coefficients of variation or specific-combining abilities suggested that these characteristics were unpredictable. The results of this study represent a potential criterion to predict progeny performances and choose parents in the breeding program.

Abstract
This paper presents a microfluidic device enabling culture of vascular smooth muscle cells (VSMCs) where extracellular matrix coating, VSMC seeding, culture, and immunostaining are demonstrated in a tubing-free manner. By optimizing droplet volume differences between inlets and outlets of micro channels, VSMCs were evenly seeded into microfluidic devices. Furthermore, the effects of extracellular matrix (e.g., collagen, poly-l-Lysine (PLL), and fibronectin) on VSMC proliferation and phenotype expression were explored. As a platform technology, this microfluidic device may function as a new VSMC culture model enabling VSMC studies.

Abstract
Virtual screening performance of support vector machines (SVM) depends on the diversity of training active and inactive compounds. While diverse inactive compounds can be routinely generated, the number and diversity of known actives are typically low. We evaluated the performance of SVM trained by sparsely distributed actives in six MDDR biological target classes composed of a high number of known actives (983-1645) of high, intermediate, and low structural diversity (muscarinic M1 receptor agonists, NMDA receptor antagonists, thrombin inhibitors, HIV protease inhibitors, cephalosporins, and renin inhibitors). SVM trained by regularly sparse data sets of 100 actives show improved yields at substantially reduced false-hit rates compared to those of published studies and those of Tanimoto-based similarity searching method based on the same data sets and molecular descriptors. SVM trained by very sparse data sets of 40 actives (2.4%-4.1% of the known actives) predicted 17.5-39.5%, 23.0-48.1%, and 70.2-92.4% of the remaining 943-1605 actives in the high, intermediate, and low diversity classes, respectively, 13.8-68.7% of which are outside the training compound families. SVM predicted 99.97% and 97.1% of the 9.997 M PUBCHEM and 167K remaining MDDR compounds as inactive and 2.6%-8.3% of the 19,495-38,483 MDDR compounds similar to the known actives as active. These suggest that SVM has substantial capability in identifying novel active compounds from sparse active data sets at low false-hit rates.

Abstract
o-Iodosobenzoic acid (IBA), in a surfactant micellar medium, is a rapid and efficient catalyst for the hydrolysis of organophosphate (OP) esters. Since little is known about the toxicity of IBA, a primary screen of neurobehavioral toxicity was evaluated in male ICR mice. IBA was administered intraperitoneally in a pH 7.4 phosphate buffer solution containing 8% dimethylformamide. The predominant overt signs of toxicity included an immediate and transient writhing reflex and/or persistent spasmodic myotwitching of the abdomen, and conspicuous suppression of orienting/exploratory behavior and emotional defecation. The dose ranges for ED50 of writhing response, suppression of rearing and spontaneous motor activity overlapped at levels of about one-tenth the acute LD50, 742 (633-856) mumol/kg, being 94.9 (74.5-122.5), 69.8 (47.9-105.4) and 71.1 (49.9-101.3) mumol/kg, respectively; the dose ranges for ED50 of abdominal myotwitching and depression of emotional defecation in a novel environment also overlapped but at levels of about one-fifth the acute LD50, being 138.4 (115.3-167.2) and 146.2 (110.7-196.3) mumol/kg, respectively. Morphine (1.25-10 mg/kg s.c.) antagonized the IBA-induced writhing response and abdominal myotwitching in a dose-dependent manner, with a PD50 of 4.2 and 4.9 mg/kg, respectively. The present report demonstrates that acute intraperitoneal administration of IBA produces an intriguing, non-specific behavioral syndrome, probably resulting from nociceptive stimulation. This implies that IBA might be irritating to the skin and mucosa.
