Abstract
Context Squalene epoxidase (SQLE) is overexpressed in a variety of tumors, which may play an important role in their tumorigenesis, development, and prognosis. Aims The aim of this study is to investigate the expression of SQLE and explore its clinicopathological significance in gastric cancer. Settings and Design The correlation between its positive expression and the pathological characteristics of patients (such as sex, age, tumor size, survival, tumor differentiation, TNM staging, and lymph node metastasis) was analyzed. Materials and Methods Immunohistochemical method was used to detect its expression in 107 cases of gastric carcinoma and 34 cases of tumor-adjacent tissues. Statistical Analysis Used Counting data were analyzed by Chi-square test. Its overall survival was analyzed by Kaplan-Meier method and log-rank test. Its hazard factors were analyzed by Cox multivariate analysis. Results The positive rate of SQLE in gastric cancer is 67.3%, which is higher than that in tumor-adjacent tissues (17.6%), <0.001. Expression of SQLE is closely related to tumor differentiation, TNM staging and lymph node metastasis (P = 0.030, P = 0.009, and P = 0.011, respectively). Furthermore, compared with those low expression of SQLE, the patients of overexpression had worse overall survival by Kaplan-Meier analysis (P = 0.025). Cox multivariate analysis shows that lymph node metastasis, tumor differentiation, SQLE, and TNM staging are independent factors for prognosis of gastric cancer (P = 0.003, 0.020, 0.018, and P = 0.001 respectively). Conclusions SQLE is overexpressed in gastric cancer. It could be used for the diagnosis and prognosis of the gastric cancer patients.

Abstract
Myocardial hypertrophy may lead to heart failure and sudden death. As traditional Chinese medicine, Guanxinning tablets (GXN) have significant pharmacological effects in the prevention and treatment of cardiovascular diseases. However, the anti-cardiac hypertrophy efficacy of GXN and its mechanism of action are still unclear. Therefore, we established a heart failure rat model and isolated primary cardiomyocytes of neonatal rat to observe the protective effect of GXN on heart failure rat model and the intervention effect on myocardial cell hypertrophy, and to explore the possible mechanism of GXN preventing and treating myocardial hypertrophy. The results of in vivo experiments showed that GXN could significantly reduce the degree of cardiac hypertrophy, reduce the size of cardiomyocytes, inhibit the degree of myocardial remodeling and fibrosis, and improve cardiac function in rats with early heart failure. The results of in vitro experiments showed that GXN was safe for primary cardiomyocytes and could improve cardiomyocyte hypertrophy and reduce the apoptosis of cardiomyocytes in pathological state, which may be related to the inhibition of the over-activation of MEK-ERK1/2 signaling pathway. In conclusion, GXN may inhibit cardiac hypertrophy and improve early heart failure by inhibiting the over-activation of MEK-ERK1/2 signaling pathway.

Abstract
Varicella-zoster virus (VZV) causes chickenpox when it first infects humans, and the virus may reactivate in adulthood and cause herpes zoster (HZ). Broad-spectrum antiviral drugs are one of the treatments for varicella and herpes zoster, but the emergence of drug resistance poses many challenges to this treatment and increases the burden of disease on patients. This paper discusses the resistance mechanisms, resistance sites and resistance detection methods of anti-VZV drugs in order to help further research on new anti-VZV targets, new drugs and monitoring of resistance to existing drugs.

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
The present study aimed to investigate the role and underlying mechanisms of long non-coding RNA (lncRNA) muscleblind-like 1 antisense RNA 1 (MBNL1-AS1) in the progression of Prostate cancer (PCa). MBNL1-AS1 and microRNA (miR)-181a-5p expression in PCa tissues and several human PCa cell lines were analyzed, respectively, using StarBasev3.0 project and RT-qPCR assay. After MBNL1-AS1 overexpression, cell proliferation, invasion and migration were, respectively, evaluated using CCK-8, colony formation, transwell and wound healing assays. Dual luciferase assay were used for analysis of the interactions among MBNL1-AS1, miR-181a-5p, and phosphatase and tensin homolog (PTEN). Subsequently, the expression of PTEN and proteins in PI3K/AKT/mTOR signaling was examined using western blot analysis after transfection with miR-181a-5p mimic. The rescue assays were performed to investigate the effects of MBNL1-AS1 and miR-181a-5p on the functions of PCa cells and the expression of PTEN/PI3K/AKT/mTOR signaling by co-transfection with MBNL1-AS1 plasmid and miR-181a-5p mimic. Results indicated that MBNL1-AS1 was conspicuously downregulated while miR-181a-5p upregulating in PCa tissues and cell lines. MBNL1-AS1 overexpression decreased the abilities of cell proliferation, invasion, and migration. Further study revealed that MBNL1-AS1 acted as a sponge for miR-181a-5p and positively regulated PTEN by a sponge effect. Additionally, rescue assays proved that the effect of MBNL1-AS1-upregulation on the proliferation, invasion, and migration of PCa cells was dependent on miR-181a-5p. Furthermore, miR-181a-5p overexpression counteracted the expression of PTEN and proteins in PI3K/AKT/mTOR signaling exerted by MBNL1-AS1-upregulation in PCa cells. This study suggests that MBNL1-AS1 inhibits the progression of PCa via sponging miR-181a-5p and regulating PTEN/PI3K/AKT/mTOR pathway.

Abstract
OBJECTIVES Health-related quality of life (HRQoL) data complement conventional clinical endpoints when comparing adjuvant gefitinib with chemotherapy in patients with early-stage non-small-cell lung cancer (NSCLC) and epidermal growth factor receptor (EGFR) mutations. This study aimed to assess changes in HRQoL with adjuvant gefitinib vs chemotherapy in this patient group. MATERIALS AND METHODS In the phase III ADJUVANT trial, patients with completely resected, stage II-IIIA (N1-N2), EGFR-mutant NSCLC were randomized (1:1) to receive either gefitinib for 24 months or vinorelbine plus cisplatin (VP) every 3 weeks for four cycles. HRQoL was assessed as a secondary endpoint using the Functional Assessment of Cancer Therapy-Lung Cancer (FACT-L), Lung Cancer Symptom Scale (LCSS) questionnaires, and Trial Outcome Index (TOI) composite score. HRQoL dynamics, improvements, and time to deterioration were compared between groups. RESULTS At baseline, 104 of 106, and 80 of 87 patients receiving gefitinib and VP, respectively, completed two questionnaires (FACT-L and LCSS). Baseline scores were balanced between groups. Although HRQoL fluctuated and gradually improved in both groups, longitudinally higher scores were reported with gefitinib than VP (FACT-L, odds ratio 418.16, 95 % confidence interval [CI] 2.75-63509.05, p = 0.019; LCSS, 1.13, 1.04-1.22, p = 0.003; TOI, 88.39, 4.40-1775.05, p = 0.003). Time to deterioration in HRQoL was delayed with gefitinib compared with VP (FACT-L, median 69 vs 6 weeks, hazard ratio 0.62, 95 % CI 0.42-0.90, p = 0.013; LCSS, median 45 vs 6 weeks, 0.63, 0.43-0.93, p = 0.020; TOI, median 164 vs 9 weeks, 0.51, 0.33-0.77, p = 0.001). CONCLUSION Adjuvant gefitinib is associated with improved HRQoL over VP, supporting its use in patients with stage II-IIIA (N1-N2), EGFR-mutant NSCLC.

Abstract
KN motif and ankyrin repeat domains 1 (Kank1) and ki67 are associated with tumorigenesis and progression. This paper researched the expression of Kank1 and Ki67 and their clinicopathologic significance in pulmonary adenocarcinoma (PA). We monitored the expression of KanK1 and ki67 in 94 cases of human PA and 31 cases of paracancerous tissue by the immunohistochemical method. The results showed that Kank1 protein was detected in 74.2% (41/94) of PA tissues, and they were associated with differentiation (P = 0.025) and lymphatic metastasis (P = 0.002). Kaplan-Meier analysis suggested that patients with low Kank1 expression had shorter overall survival in PA (P = 0.020). Ki67 protein was detected in 79.8% (75/94) of PA tissues, and they were associated with differentiation (P < 0.001), TNM classification (P = 0.007), and lymphatic metastasis (P = 0.044). Furthermore, Kaplan-Meier analysis showed that patients with overexpression of Ki67 had shorter overall survival (P = 0.014). Cox multivariate analysis showed that tumor differentiation, TNM classification, lymphatic metastasis, Kank1, and ki67 expression were independent factors for prognosis of PA (P = 0.012, 0.016, 0.007, 0.021 and P = 0.003 respectively). In conclusion, compared with paracancerous tissues, Kank1 had low expression, while Ki67 was overexpressed in PA. They are closely related to its occurrence and development, and the prognosis of patients with low expression of Kank1 or overexpression of ki67 was poor in PA. Kank1 and Ki67 can be helpful for diagnosing and detecting the prognosis of patients with PA.

Abstract
Progesterone and adipoQ receptor family member 3 (PAQR3) and vascular endothelial growth factor (VEGF)-A are associated with tumorigenesis and progression. The aim of this study is to investigate the expression of PAQR3 and VEGF-A in pulmonary adenocarcinoma (PA) and explore their clinical and pathologic significance. The expressions of PAQR3 and VEGF-A protein were detected in 86 cases of human PA and 26 cases of tumor-adjacent tissue by immunohistochemistry. The positive rate of PAQR3 was 39.5% in PA, which was lower than that in tumor-adjacent tissues (80.8%), P=0.001. Negative expression of PAQR3 was obviously linked to tumor TNM stage, differentiation, and lymphatic metastasis; and P values were 0.013, 0.025, and 0.034, respectively. The positive expression rate of VEGF-A was 68.6% in human PA whichwas higher than that of tumor-adjacent tissues (11.5%), P<0.001. The positive expression of VEGF-A was correlated with tumor TNM stage, differentiation, and lymphatic metastasis, and P values were 0.026, 0.001 and P=0.001, respectively. The expression of PAQR3 was negatively correlated with the expression of VEGF-A (r=-0.698, P<0.001). Log-rank test statistical analysis suggested that patients with negative expression of PAQR3 or positive expression of VEGF-A had shorter overall survival. Cox multivariate analysis indicated that tumor TNM stage, differentiation, and lymphatic metastasis, and PAQR3 and VEGF-A expression were independent factors for prognosis of PA, and P values were 0.021, 0.017, 0.006, 0.018 and P=0.007 respectively. In conclusion, negative expression of PAQR3 and positive expression of VEGF-A are markedly correlated with tumor TNM classification, histologic grade, and lymphatic metastasis. Tumor TNM stage, differentiation, and lymphatic metastasis, negative expression of PAQR3, and positive expression of VEGF-A are risk factors for prognosis of patients with PA. Detection of PAQR3 and VEGF-A may be helpful to evaluate prognosis and infiltrative capability of PA.

Abstract
9005 Background: ADJUVANT-CTONG1104, a randomized phase 3 trial showed adjuvant gefitinib treatment significantly improved disease-free survival (DFS) vs standard doublet chemotherapy in patients (pts) with epidermal growth factor receptor ( EGFR) mutation-positive resected stage II-IIIA (N1-N2) non-small-cell lung cancer (NSCLC). 5-year survival rate of N1N2 were 38%-50% in IASLC staging system. Here, we present the final overall survival (OS) results from the study. Methods: From Sep 2011 to April 2014, 222 patients, aged 18-75 years, with EGFR activating mutation through completely resection and diagnosed as stage II-IIIA (N1-N2) NSCLC pathologically from 27 sites were enrolled. The enrolled patients were 1:1 randomized to receive adjuvant gefitinib (250 mg once per day) for 24 months (G, n=111) or vinorelbine (25 mg/m2, d1 and d8) plus cisplatin (75 mg/m2, d1) every 3 weeks for 4 cycles (C, n=111). The primary endpoint was DFS in the ITT population. Secondary endpoints included OS, 3 and 5-year DFS rate, 5-year OS rate. The subsequent therapy data were collected, including crossover from C to G, re-challenge TKI and other treatment. Data cut-off date was Jan. 13, 2020. Results: A median follow-up was 76.9 months. The median OS (mOS) was 75.5 months based on 95 (42.8%) events in ITT whole population. The mOS was 75.5m in G arm and 79.2m in C arm (HR 0.96, 95%CI 0.64-1.43, p=0.823). The 3, 5-year OS rate were 68.6%, 53.8% in G and 67.5%, 52.4% in C respectively. DFS in 3, 5-y were 40.3%, 23.4% in G and 33.2%, 23.7% in C, respectively (P3-y=0.395, P5-y=891). All predefined subgroups including age, gender, lymph node, EGFR mutation type had no significant difference in statistics but in favor of G arm in trend. Subsequent treatment especially targeted therapy contributed most to OS (HR = 0.46, 95% CI 0.26 – 0.83). Median OS of patients receiving subsequent target therapy was75.5m (n=35), 36.4m in other treatment (n=33; (P<0.001). For G mOS were 75.5 (n=15; target therapy) and 35.0 (n=18; other, p<0.001), for C 62.8m (n=20) and 46.8m (n=15; p=0.251). The RR was 26.7%, DCR 66.7%, mPFS 14.1m and mOS 19.6m for patients with rechallenged EGFR TKI in G arm (n=15). No novel unexpected SAE was observed during follow up. Conclusion The DFS survival advantage did not translate to OS difference in ADJUVANT trial. The OS with 75.5m was the best one of survival in completely resected N1N2 NSCLC comparing with historical data and sequent TKI treatment contribute to overall survival. Clinical trial information: NCT01405079.

Abstract
Radioresistance is an important factor affecting the radiotherapy effect of colorectal cancer (CRC). Allicin is a versatile sulfur-containing organic compound extracted from garlic (Allium sativum L.), which has many pharmacological effects. However, the effect of allicin on the sensitivity of CRC radiotherapy has not been confirmed. The present study is to observe the radiosensitivity effects of allicin and to explore its mechanism in CRC radiotherapy. The proliferation inhibition effects of allicin combined with X-ray radiotherapy in HCT116 cells were measured by growth curve of cell and colony formation assays. The cell apoptosis was detected by Hoechst 33258 nucleus staining assay. The migration ability of cells was detected by Transwell chamber migration assay. The animal model of CRC was established in BALB/c mice via transplantation of CT26 cell, and the radiosensitization effect of allicin on CRC was detected in vivo. The mRNA expressions of NF-κB, IKKβ, and IκBα were analyzed by reverse transcription-polymerase chain reaction (RT-PCR). The protein expressions of NF-κB, p-NF-κB, IKKβ, p-IKKβ, IκBα, and p-IκBα were detected by western blotting. Our results showed that allicin improves the sensitivity of X-ray radiotherapy in CRC, and its mechanism may be associated with inhibition of NF-κB signaling pathway. These findings suggest that allicin may be used as a potential sensitizer for tumor radiotherapy in the clinic.

Abstract
Hepatic injury is one of the most common digestive system diseases worldwide in clinic. Guanylic acid or guanosine monophosphate (GMP) was an important component of nucleotides, which is mainly in the form of sodium salt (disodium guanylate, GMP-Na2 ). However, its effect on hepatic injury has not yet been investigated. This study is to investigate the protective effects of GMP-Na2 on acute hepatic injury induced by carbon tetrachloride (CCl4 ), and to explore its mechanism. The hepatic injury models of mice and HL-7702 cells were induced by CCl4 . The alanine transaminase (ALT), aspartate aminotransferase (AST), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), total antioxidant capacity (T-AOC) were determined by biochemical method. Hematoxylin-eosin staining were used to determine the morphological changes on liver tissue in mice. The mRNA and protein expressions of caspase-3, Bax, and Bcl-2 were detected by RT-PCR and Western blot analysis. Our results show that GMP-Na2 treatment significantly decreased the activities of ALT and AST, and the levels of MDA as well as increased the levels of SOD, GSH-Px, and T-AOC. Importantly, GMP-Na2 effectively enhanced the antiapoptosis function by upregulating Bcl-2 expression and downregulating caspase-3 and Bax expressions in vivo and in vitro. Moreover, the histopathological changes of liver tissue were obviously improved after GMP-Na2 treatment. These findings suggest that GMP-Na2 has protective effects on hepatic injury, and its mechanisms may be associated with antioxidative stress and antiapoptosis.

Abstract
The purpose of this article is to study whether the overexpression of urokinase-type plasminogen activator (uPA) can promote the proliferation and fibrinolytic activity of human umbilical vein endothelial cells (HUVECs). The recombinant adenovirus vectors containing the human uPA gene were constructed and transfected into HUVECs. In this study, the mRNA of uPA was detected by qPCR, and the uPA protein was measured by Western blot. The cell proliferation was measured using MTT. The fibrinolytic activity of uPA was quantified using a colorimetric assay. We also measured MMP2 (metalloproteinase-2), MMP9 (metalloproteinase-9), and VEGF (vascular endothelial growth factor) proteins using ELISA. The results showed that the levels of the uPA mRNA and the protein in the overexpression group were significantly higher compared to the other groups, (P < 0.05). The cell proliferation and uPA activity were increased significantly in the overexpression group, compared to the other groups, (P < 0.05). The secretions of MMP2, MMP9, and VEGF in the overexpression group were significantly higher than they were in the other two groups (P < 0.05). In conclusion, we successfully transfected a recombined adenovirus vector carrying uPA into a HUVEC. The exogenous uPA gene could transcribe and secrete the uPA protein in the HUVECs. The overexpression of uPA can increase cell proliferation and uPA activity. It can improve the invasion and angiogenesis ability in HUVECs by promoting their secretions of MMP2, MMP9, and VEGF.

Abstract
OBJECTIVE In the era of fast track surgery, early and accurately estimating whether postoperative length of stay (p-LOS) will be prolonged after lung cancer surgery is very important, both for patient's discharge planning and hospital bed management. Pulmonary function tests (PFTs) are very valuable routine examinations which should not be underutilized before lung cancer surgery. Thus, this study aimed to establish an accurate but simple prediction tool, based on PFTs, for achieving a personalized prediction of prolonged p-LOS in patients following lung resection. METHODS The medical information of 1257 patients undergoing lung cancer surgery were retrospectively reviewed and served as the training set. p-LOS exceeding the third quartile value was considered prolonged. Using logistic regression analyses, potential predictors of prolonged p-LOS were identified among various preoperative factors containing PFTs and intraoperative factors. A nomogram was constructed and subjected to internal and external validation. RESULTS Five independent risk factors for prolonged p-LOS were identified, including older age, being male, and ratio of residual volume to total lung capacity (RV/TLC) ≥ 45.0% which is the only modifiable risk factor, more invasive surgical approach, and surgical type. The nomogram comprised of these five predictors exhibited sufficient predictive accuracy, with the area under the receiver operating characteristic curve (AUC) of 0.76 [95% confidence interval (CI) 0.73-0.79] in the internal validation. Also its predictive performance remained fine in the external validation, with the AUC of 0.70 (95% CI 0.60-0.79). The calibration curves showed satisfactory agreements between the model predicted probability and the actually observed probability. CONCLUSIONS Preoperative amelioration of RV/TLC may prevent lung cancer patients from unnecessary prolonged p-LOS. The integrated nomogram we developed could provide personalized risk prediction of prolonged p-LOS. This prediction tool may help patients perceive expected hospital stays and enable clinicians to achieve better bed management after lung cancer surgery.

Abstract
Astrocyte elevated gene-1 (AEG-1) and E-cadherin are associated with tumorigenesis and progression. The aim of this study is to investigate the expression of AEG-1 and E-cadherin in human gallbladder cancer (GBC) and explore their clinical and pathological significance. The expression of AEG-1 and E-cadherin protein were detected in 71 cases of human GBC and 22 cases of tumor-adjacent tissue by the immunohistochemical method. Our results demonstrate that the positive expression (high expression) rate of AEG-1 was 62.0% in human GBC which was higher than that in tumor-adjacent tissues (13.6%), P<0.001. The positive expression of AEG-1 protein was correlated with tumor TNM classification, histologic grade, and lymph node metastasis (P=0.037, P=0.033 and P=0.020, respectively). The positive expression rate of E-cadherin was 40.8% in GBC, which was lower than that in tumor-adjacent tissues (77.3%), P=0.003. Negative expression (Low expression) of E-Cadherin was significantly related with tumor TNM classification, histologic grade and lymphatic metastasis (P=0.028, P=0.003 and P=0.040, respectively). The expression of AEG-1 was negatively correlated with the expression of E-Cadherin (r=0.530, P<0.001). The log-rank test statistical analysis suggested that patients with positive expression of AEG-1 or negative expression of E-Cadherin protein had shorter overall survival time. Cox multivariate analysis showed that tumor TNM classification, histologic grade and lymphatic metastasis, AEG-1 and E-cadherin expression were independent factors for prognosis of GBC (P=0.013, P=0.019, P=0.001, P=0.011 and P=0.025 respectively). In conclusion, positive expression of AEG-1 and negative expression of E-Cadherin are markedly correlated with tumor TNM classification, histologic grade and lymphatic metastasis. The expression of AEG-1 was negatively correlated with the expression of E-Cadherin. Cox multivariate analysis showed that tumor TNM classification, histologic grade and lymphatic metastasis, positive expression of AEG-1 and negative expression of E-Cadherin were risk factors for prognosis of GBC. Detection of AEG-1 and E-Cadherin may be helpful to evaluate prognosis and infiltrative capability of gallbladder carcinoma.

Abstract
Background: Patients with early stage lung cancer seldom present initial respiratory symptoms, causing a delayed diagnosis and missed opportunity to receive operation. This study aimed to investigate the prevalence of initial respiratory symptoms and identity what factors would predispose lung cancer patients to present initial respiratory symptoms in patients undergoing lung cancer surgery. Methods: A retrospective chart review was conducted on 3,203 patients undergoing surgery for primary lung cancer. The prevalence of initial respiratory symptoms was investigated and the comparisons of clinicopathological parameters were performed between patients with and without initial respiratory symptoms or between patients with single and multiple initial respiratory symptoms. Independent risk factors for presenting initial respiratory symptoms or multiple initial respiratory symptoms were identified using a logistic regression. Results: A total of 1,474 (46.0%) patients with lung cancer were admitted to hospital due to present initial respiratory symptoms. Symptom clusters of cough or sputum (33.1%) and bloody sputum or hemoptysis (16.7%) presented as the two major chief complaints for medical consultation while chest pain (6.9%) and chest distress or dyspnea (5.6%) remained relatively unusual. Multiple analyses found that coexisting chronic obstructive pulmonary disease (OR=1.70, 95% CI=1.41-2.05), tumor size >3 cm (OR=2.27, 95% CI=1.93-2.67), squamous cell carcinoma (OR=2.22, 95% CI=1.86-2.65), tumor located in left lower lung (OR=1.39, 95% CI=1.10-1.74) and advanced tumor stage (OR=1.27, 95% CI=1.06-1.52) were independent risk factors for presenting initial respiratory symptoms. Furthermore, current smoking (OR=1.36, 95% CI=1.07-1.73), tumor size >3 cm (OR=1.53, 95% CI=1.21-1.93) and squamous cell carcinoma (OR=1.68, 95% CI=1.32-2.15) were demonstrated to be independent risk factors for presenting multiple initial respiratory symptoms. Conclusions: Presenting initial respiratory symptoms was the common cause for medical consultation in patients undergoing lung cancer surgery. Patients with lung cancer in larger tumor size or squamous cell carcinoma more likely presented initial and even multiple initial respiratory symptoms.

Abstract
Objective: To analyze the genetic characterization of glycoprotein M(gM.),glycoprotein L(gL) of varicella zoster virus. Methods: According to the program of "Ministry of Science and Technology of China" , Based on the 12 suspected VZV patients monitored in Beijing (1 case), Shanghai (5 cases), Jilin (2 cases), Qinghai (1 case), Guangdong (2 case) and Sichuan (case) in 2007-2015. A total of 12 Vesicle fluid and throat swab samples were collected. Positive samples were identified by Agarose gel electrophoresis and two glycoprotein genes were amplified by polymerase chain reaction (PCR). Nucleotide sequences were determined and analyzed by PCR amplification of VZV positive specimens V-OKA-BK of the domestic varicella attenuated live vaccine and the Varilrix-1 of the imported attenuated live vaccine. Nucleotide sequences of VZV positive specimens, vaccine strains (V-OKA-BK, varilrix-1) and GenBank foreign wild strains (41 strains), parent strains (P-oka), vaccine strains (V-oka, Varilrix, Varivax) were compared using BioEdit and MEGA 5.0. Results: 12 specimens were VZV positive. Compared with the vaccine strains and the parent strains, the GM gene of 1 positive specimen had radical mutation at 86686 sites, which resulted in amino acid mutation, 5 positive specimens had base mutation at 87844 sites, and 30 strains of foreign wild strains had the same variation at 87 844 sites. 1 positive specimens of gL gene in 101245 sites had base mutation, and led to amino acid mutation, 6 positive specimens at 101624, 101625, 101626 sites had base of loss and the foreign wild strains in these 3 sites had the same variation. Compared with the vaccine strains, the nucleotide and amino acid homology of gM of 12 VZV positive specimens were 99.2%-100% and 98.2%-100%, respectively, and gL of those were 99.3%-100% and 98.6%-100%, respectively. Compared with 41 strains of foreign wild strains, homology of gM's nucleotides and amino acid were 99.3%-100% and 98.5%-100%, respectively; 99.1%-100% and 98.6%-100% for gL. The results of phylogenetic analysis showed that 7 VZV positive samples were on the same branch with 4 vaccine strains and p-oka strain. Based on gL, 12 VZV positive samples were on the same branch as the vaccine strains and p-oka strain. Conclusion: This study demonstrates that the genes of gM, gL are highly conserved and remain stable immunogen, which may be involved in the attenuation of VZV and need to be further researched.

Abstract
Background Lung cancer is often complicated with chronic obstructive pulmonary disease (COPD). Coexistence of COPD has significant impacts on the decision-making process for lung cancer surgery as well as the postoperative effects. This study aimed to investigate the status of coexisting COPD and analyze its clinicopathological characteristics in lung cancer patients undergoing surgical resection. Methods Clinical data of 3,006 patients with resected primary lung cancer from January 2008 to April 2014 were analyzed. Status of coexisting COPD was evaluated according to patient's lung function. Differences of clinicopathological characteristics between the COPD group and the non-COPD group were compared. Results A total of 643 patients (21.4%) were complicated with COPD. The average age of patients with COPD (64.9±8.5 years) was significantly older than those without COPD (59.4±9.9 years). The percentage of males (85.7% vs. 54.0%) and current smokers (43.4% vs. 22.5%) were both higher in the COPD group than the non-COPD group (P<0.05). The percentage of patients with initial symptoms was higher in the COPD group than the non-COPD group (63.9% vs. 44.5%, P<0.05). The average white blood cell count was higher in the COPD group than the non-COPD group [(6.72±2.28 vs. 6.28±2.24) ×109/L, P<0.05]. The percentage of tumor size more than 3 cm was higher in the COPD group than the non-COPD group (53.2% vs. 38.0%, P<0.05). Squamous cell carcinoma accounted for 47.6% in the COPD group while adenocarcinoma accounted for 72.4% in the non-COPD group (P<0.05). A higher percentage of lung cancer with poor differentiation was found in the COPD group than the non-COPD group (53.2% vs. 43.6%, P<0.05). The median total and postoperative length of hospital stay were significantly longer in the COPD group than the non-COPD group (13 vs. 11 days, 8 vs. 7 days, respectively, P<0.05). Conclusions COPD is a common comorbidity of early stage lung cancer. Lung cancer patients with coexistence of COPD have obviously different clinicopathological features compared to patients without COPD, which requires special attention and management during the perioperative period of lung cancer.

Abstract
BACKGROUND Cisplatin-based adjuvant chemotherapy is the standard of care for patients with resected stage II-IIIA non-small-cell lung cancer (NSCLC). RADIANT and SELECT trial data suggest patients with EGFR-mutant stage IB-IIIA resected NSCLC could benefit from adjuvant EGFR tyrosine kinase inhibitor treatment. We aimed to compare the efficacy of adjuvant gefitinib versus vinorelbine plus cisplatin in patients with completely resected EGFR-mutant stage II-IIIA (N1-N2) NSCLC. METHODS We did a randomised, open-label, phase 3 trial at 27 centres in China. We enrolled patients aged 18-75 years with completely resected (R0), stage II-IIIA (N1-N2), EGFR-mutant (exon 19 deletion or exon 21 Leu858Arg) NSCLC. Patients were stratified by N stage and EGFR mutation status and randomised (1:1) by Pocock and Simon minimisation with a random element to either gefitinib (250 mg once daily) for 24 months or intravenous vinorelbine (25 mg/m2 on days 1 and 8) plus intravenous cisplatin (75 mg/m2 on day 1) every 3 weeks for four cycles. The primary endpoint was disease-free survival in the intention-to-treat population, which comprised all randomised patients; the safety population included all randomised patients who received at least one dose of study medication. Enrolment to the study is closed but survival follow-up is ongoing. The study is registered with ClinicalTrials.gov, number NCT01405079. FINDINGS Between Sept 19, 2011, and April 24, 2014, 483 patients were screened and 222 patients were randomised, 111 to gefitinib and 111 to vinorelbine plus cisplatin. Median follow-up was 36·5 months (IQR 23·8-44·8). Median disease-free survival was significantly longer with gefitinib (28·7 months [95% CI 24·9-32·5]) than with vinorelbine plus cisplatin (18·0 months [13·6-22·3]; hazard ratio [HR] 0·60, 95% CI 0·42-0·87; p=0·0054). In the safety population, the most commonly reported grade 3 or worse adverse events in the gefitinib group (n=106) were raised alanine aminotransferase and asparate aminotransferase (two [2%] patients with each event vs none with vinorelbine plus cisplatin). In the vinorelbine plus cisplatin group (n=87), the most frequently reported grade 3 or worse adverse events were neutropenia (30 [34%] patients vs none with gefitinib), leucopenia (14 [16%] vs none), and vomiting (eight [9%] vs none). Serious adverse events were reported for seven (7%) patients who received gefitinib and 20 (23%) patients who received vinorelbine plus cisplatin. No interstitial lung disease was noted with gefitinib. No deaths were treatment related. INTERPRETATION Adjuvant gefitinib led to significantly longer disease-free survival compared with that for vinorelbine plus cisplatin in patients with completely resected stage II-IIIA (N1-N2) EGFR-mutant NSCLC. Based on the superior disease-free survival, reduced toxicity, and improved quality of life, adjuvant gefitinib could be a potential treatment option compared with adjuvant chemotherapy in these patients. However, the duration of benefit with gefitinib after 24 months might be limited and overall survival data are not yet mature.

8500 Background: Cisplatin-based adjuvant chemotherapy is standard of care for patients (pts) with stage II-IIIA non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors have shown no benefits in the adjuvant setting for pts with unselected resected NSCLC in the BR19 and RADIANT trials. ADJUVANT (NCT01405079) is the first randomized trial to compare gefitinib (G) with vinorelbine+cisplatin (VP) in completely resected pathological stage II-IIIA (N1-N2) NSCLC with EGFR-activating mutation. Methods: Completely resected stage II-IIIA (N1-N2) NSCLC pts with EGFR-activating mutation were randomized 1:1 to receive G (250 mg once daily) for 24 months or vinorelbine (25 mg/m2 Day 1 and Day 8) plus cisplatin (75 mg/m2 Day 1) every 3 weeks for 4 cycles. Stratification factors were lymph node status (pN1/N2) and EGFRmutation status. The primary endpoint was disease-free survival (DFS) in the intent-to-treat population. Results: A total of 222 pts were randomly assigned (Sep 19 2011 to Apr 24 2014). Baseline characteristics were balanced. At the time of data cutoff, the median duration of treatment was 21.9 months in the G arm, and 4 cycles in the VP arm. The median follow-up period was 36.5 months (range 0.1 to 62.8). G had significantly longer median DFS (28.7 months, 95% confidence interval [CI] 24.9 to 32.5) than VP (18.0 months, 95% CI 13.6 to 22.3; hazard ratio 0.60; 95% CI 0.42 to 0.87; p= 0.005). 3-year DFS was significantly better with G (34.0% vs 27.0%; p= 0.013). The number of overall survival events was 76 (34.2%). In the subgroup analysis of patients treated with G, lymph node status (pN1/N2) demonstrated significant correlation with DFS ( p< 0.05). Grade 3 or higher adverse events were less common with G than with VP (12.3% vs 48.3%; p< 0.001). No interstitial lung disease was observed with G. Conclusions: Adjuvant G significantly prolonged DFS compared with VP in pts with resected stage II-IIIA (N1-N2) NSCLC with EGFR-activating mutation. Adjuvant gefitinib should be considered as an important option for stage II-IIIA lung cancer pts with EGFR mutation. Clinical trial information: NCT01405079.

Abstract
Objective To retrospectively evaluate appropriate treatment for patients with symptomatic caliceal diverticular calculi, by comparing the therapeutic outcomes for those undergoing minimally invasive percutaneous nephrolithotomy (MPCNL) and flexible ureterorenoscopy (F-URS). Methods From March 2009 to May 2014, 36 consecutive patients with caliceal diverticular calculi were divided into 2 groups: 21 patients underwent MPCNL, and 15 were treated by F-URS. All procedures were performed by one surgical group, which ensured relatively constant parameters. Patient characteristics, operative time, hospital stay after surgery, stone-free rate, symptomatic improvement rate, complications, diverticular obliteration, and stone composition were analyzed retrospectively in the 2 groups. Results Patient preoperative variables were comparable between the two groups, with no significant difference (P > 0.05). Mean operative time was 136.9 ± 22.8 min in the MPCNL group and 117.3 ± 24.3 min in the F-URS group (P = 0.019). Hospital stay was significantly longer in the MPCNL group than in the F-URS group (9.4 ± 3.1 vs. 6.9 ± 2.1 days, P = 0.010). The stone-free rates after MPCNL and F-URS were 90.5% (19/21) and 60.0% (9/15), respectively (P = 0.046). Additionally, 71.4% (15/21) of patients in the MPCNL group and 46.7% (7/15) of patients in the F-URS group had symptomatic improvement at the 6-month follow-up (P = 0.175); the rates of complications in the 2 groups were 19.0% (4/21) and 13.3% (2/15), respectively (P = 0.650). Complete diverticular obliteration was achieved in 16 (76.2%) cases in the MPCNL group and 5 (33.3%) cases in the F-URS group (P = 0.017). The distributions of calcium oxalate and hydroxyapatite in the stones were 66.7% (14/21) and 33.3% (7/21), respectively, in the MPCNL group; however, the distributions in the F-URS group were 46.7% (7/15) and 53.3% (8/15), respectively (P = 0.310). Conclusion MPCNL is an effective method for the treatment of caliceal diverticular calculi. However, F-URS is an alternative technique in selected patients with a patent infundibulum, despite lower stone-free rates than with MPCNL. Fulguration of the diverticular lining with a high-power holmium laser and permitting the cavity to collapse are useful to increase the chance of diverticular obliteration.

Abstract
OBJECTIVE To clarify the genotype of wild-type strains of varicella zoster virus (VZV) in Jilin province in 2014, and to discriminate between v-Oka vaccine strains and wild-type strains. METHODS Vesicle fluid and throat swab samples were collected from 13 individuals with suspected VZV in Jilin province from January to December 2014. Viral DNA was extracted, the fragments of 15 open reading fragments (ORFs) were amplified by polymerase chain reaction (PCR), and viral genotypes were determined by single nucleotide polymorphisms (SNP). PCR restriction fragment length polymorphism (RFLP) was used to distinguish between wild-type strains and v-Oka vaccine strains. The results were analyzed with MEGA5 software, using the VZV reference strain sequences from GenBank. RESULTS The 13 suspected samples included 5 males and 8 females, aged 11-27 years (mean: (16.69±5.48) years). Sampling was performed on days 0 to 3 of suspected infection. VZV strains were detected in 8 samples, all belonging to Clade 2. There was a synonymous mutation (T>C) in SNP18082 compared with the v-Oka vaccine strain. Analysis of PCR-RFLPs showed that all 8 positive samples were wild-type strains (PstⅠ(+)BglⅠ(+)SmaⅠ(-)). CONCLUSIONS The study revealed that the VZV strains circulating in Jilin province in 2014 were wild-type strains belonging to Clade 2.

Abstract
The purpose of this article is to research on whether MACC1 can serve as a potential target for gene therapy of human bladder urothelial carcinoma (BUC). In this study, the expression of MACC1 gene was knocked down by RNA interference (RNAi) in the T24 cell (human BUC cell). The transcription level of MACC1 was detected by RT-PCR. Activities of MACC1, caspase-3, caspase-8, Bax and Met (mesenchymal-epithelial transition factor) protein were measured by Western blot. The cell proliferation and apoptosis were detected by MTT and flow cytometry. The cell's invasion ability was performed on Matrigel transwell assay. We also detect MMP2 (metalloproteinase-2) proteins by ELISA. The results showed that the level of MACC1 mRNA and protein was significantly reduced after RNAi. MTT assay showed that the proliferation of T24 cell was decreased due to RNA interference. Apoptosis studies also showed that MACC1 gene interference in T24 loses its anti-apoptotic effects. The expression of apoptosis proteins (Caspase-3, Caspase-8 and Bax) increased significantly due to the MACC1 RNAi. The level of Met protein was down-regulated obviously due to RNAi. Transwell assay showed that invasion abilities of T24 cells were reduced obviously due to MACC1 RNAi. Further studies showed that the secretion of MMP-2 was reduced by RNAi. It can conclude that the ability of proliferation and invasion in T24 cells can be inhibited by RNAi-targeting MACC1. As a result, MACC1 can serve as a potential target for gene therapy of human bladder urothelial carcinoma.

Abstract
Well-dispersed uniform cobalt ferrite nanoparticles were synthesized by thermal decomposition of a metal-organic salt in organic solvent with a high boiling point. Some of the nanoparticles were diluted in a SiO2 matrix and then the undiluted and diluted samples were characterized and their magnetic behavior explored. The undiluted and diluted samples exhibited maximum coercivity Hc of 23,817 and 15,056 Oe at 10 K, respectively, which are the highest values reported to date, and the corresponding ratios of remanence (Mr) to saturation (Ms) magnetization (Mr/Ms) were as high as 0.85 and 0.76, respectively. Interestingly, the magnetic properties of the samples changed at 200 K, which was observed in magnetic hysteresis M(H) loops and zero-field cooling curves as well as the temperature dependence of Hc, Mr/Ms, anisotropy, dipolar field, and the magnetic grain size. Below 200 K, both samples have large effective anisotropy, which arises from the surface spins, resulting in large Hc and Mr/Ms. Above 200 K, the effective anisotropy decreases because there is no contribution from surface spins, while the dipolar interaction increases, resulting in small Hc and Mr/Ms. Our results indicate that strong anisotropy and weak dipolar interaction tend to increase Hc and Mr/Ms, and also clarify that the jumps around H = 0 in M(H) loops can be attributed to the reorientation of surface spins. This work exposes the underlying mechanism in nanoscale magnetic systems, which should lead to improved magnetic performance.

Abstract
Osteopontin (OPN) involves in tumor formation, and strongly correlated with the tumor progression. It was overexpressed in human esophageal squamous cell carcinoma (ESCC). To study the molecular mechanisms of OPN in ESCC, we examined its roles in inhibiting proliferation and invasion of ECA-109 (esophageal squamous cell carcinoma) cells. The expression of OPN gene was knockdown by RNA interference (RNAi) in the Eca-109 cell. The transcription level of OPN was to detect by reverse transcription-quantitative PCR (RT-qPCR). Western blot assay was performed to detect the expression of OPN, Caspase-3,Caspase-8, Caspase-9, ERK1/2, phospho-ERK1/2 and MMP2 after RNAi. The cell proliferation and apoptosis were detected by MTT and Hoechst33342 assay. Transwell inserts was used for detecting ECA-109 cell's migration ability. The results shown that the level of OPN mRNA and protein was significantly reduced after RNAi. Proliferation and migration of cell line (ECA-109) was significantly inhibited in vitro. The protein phosphorylation and activation of ERK1/2 in the OPN RNAi group reduced significantly than the negative control groups. In Conclusion, the proliferation and migration of human ESCC can be inhibited by RNAi-targeting OPN. OPN can promote the expression of MMP2 through the ERK signaling pathways. OPN could serve as a potential therapeutic target for human ESCC.

Abstract
Osteopontin (OPN), a secreted acid glycoprotein with a variety of functions, promotes tumor proliferation, differentiation, invasion and metastasis. The aim of the current study was to investigate whether OPN may serve as a potential therapeutic target for human bladder cancer. RNA interference (RNAi) was performed to downregulate the expression of the OPN gene in T24 human bladder cancer cells. The mRNA and protein expression levels of OPN following RNAi were determined using reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively. In addition, the cell cycle progression, apoptosis and proliferation were investigated using by flow cytometric analysis and MTT assay. The cell invasion ability was measured using a Matrigel transwell assay. The mRNA and protein expression levels of OPN were found to be significantly downregulated following RNAi. The proliferation and invasion of T24 cells were significantly inhibited in vitro. In conclusion, RNAi‑targeting OPN may inhibit the proliferation, invasion and tumorigenicity of human bladder cancer cells. Therefore, OPN may serve as a potential therapeutic target for human bladder cancer.

Abstract
OBJECTIVE To investigate the potential relevance of c-Met and RON gene expression in patients with adenocarcinoma of the endometrium and analyze the relationships among the c-Met and RON expression, clinicopathological characteristics, and patient survival. MATERIALS AND METHODS The study included 60 cases diagnosed with endometrial adenocarcinoma with more than five-years follow-up. Total RNA from formalin-fixed paraffin-embedded tissues of 60 adenocarcinomas of the endometrium and normal endometrium tissues were isolated for c-Met and RON quantitative analysis by real-time real-time polymerase chain reaction (RT-PCR). RESULTS The c-Met and RON expression in endometrial adenocarcinoma was significantly higher than that in normal endometrial tissues (p < 0.01), with average up-regulated levels of 3.94 ± 1.88 and 2.74 ± 0.88, respectively. Moreover, high c-Met expression was significantly correlated with the histological stage (p = 0.017), and high RON expression was related to histological stage (p = 0.035), muscle invasion (p = 0.006), and lymph node metastasis (p = 0.018). Multivariate Cox regression analysis revealed that the co-expression of c-Met and RON was an independent prognostic factor for adenocarcinoma of the endometrium and was significantly associated with decreased overall survival (HR = 3.571, p = 0.014). CONCLUSION The co-expression of c-Met and RON is associated with a poor prognosis in endometrial adenocarcinoma and is an independent prognostic marker for endometrioid adenocarcinoma.

Abstract
OBJECTIVE To study the effects of desmopressin (DDAVP) on coagulation factor Ⅷ (FⅧ) and activated partial thromboplastin time (APTT) in children with mild hemophilia A. METHODS Eighteen children with mild hemophilia A were enrolled. DDAVP (0.3 μg/kg•d) was injected intravenously for 5 days. Plasma FⅧ levels and APTT were measured before and after DDAVP treatment. RESULTS In 16 of 18 children with mild hemophilia A, the bleeding symptoms, including the articular or musclar hematoma, were significantly alleviated as a result of DDAVP treatment. The plasma FⅧ levels increased significantly to (27±4)% and APTT was shortened to (66±10)s 60 minutes after the first dose of DDAVP treatment. The plasma FⅧ remained at the levels of 25%-30% during 3-4 days of DDAVP treatment. Five days after DDAVP treatment, the plasma FⅧ levels decreased [(21±3)%], and APTT was prolonged when compared with 1-4 days of DDAVP treatment. CONCLUSIONS DDAVP treatment can increase plasma FⅧ levels and shorten APTT in children with mild hemophilia A. DDAVP is effective in the treatment of mild hemophilia A. The duration of DDAVP therapy for mild hemophilia A is recommended as 3 to 4 days.

Abstract
Varicella is an acute, highly contagious respiratory and caused by Varicella-zoster virus (VZV). After the primary infection, VZV induce Varicella, then the virus remains dormant in sensory nerve roots in life. Upon the reactivation, shingles can occur. Most of patients can recovery very soon, but kinds of potentially severe complication can induce death. Nowadays the VZV vaccination isn't included in the expanded immunization program in our country. Varicella outbreaks take place at times in the middle of children of our country. The paper offers concise description about pathogen characteristics, diagnosis methods, clinical character, epidemiology knowledge and strategy of prevention.

Abstract
BACKGROUND Human bocavirus (HBoV) is a parvovirus recently found to possibly cause respiratory tract disease in children and adults. This study investigated HBoV infection and its clinical characteristics in children younger than five years of age suffering from acute lower respiratory tract infection in Beijing Children's Hospital. METHODS Nasopharyngeal aspirates were collected from children suffering from acute lower respiratory tract infection during the winters of 2004 to 2006 (from November through the following February). HBoV was detected by polymerase chain reaction amplification and virus isolation and the amplification products were sequenced for identification. RESULTS HBoV infection was detected in 16 of 333 study subjects. Coinfections with respiratory syncytial virus were detected in 3 of 16 HBoV positive patients with acute lower respiratory tract infection. The median age for HBoV positive children was 8 months (mean age, 17 months; range, 3 to 57 months). Among the HBoV positive children, 14 were younger than 3 years old, 9 were younger than 1 year old and 7 were younger than 6 months. These 16 positive HBoV children exhibited coughing and abnormal chest radiography findings and more than 60% of these children had wheezing and fever. Ten children were clinically diagnosed with pneumonia, 2 bronchiolitis, 2 acute bronchitis and 2 asthma. One child died. CONCLUSIONS HBoV was detected in about 5% of children with acute lower respiratory infection seen in Beijing Children's Hospital. Further investigations regarding clinical and epidemiologic characteristics of HBoV infection are needed.

Abstract
57 rubella virus strains were isolated using Vero cell line or Vero/SLAM cell line from patients' throat swabs during rubella outbreaks and sporadics in 10 provinces of China from 2003 to 2007. Fragments of 1107 nucleotides of E1 genes of the isolates were amplified by RT-PCR, the PCR products were directly sequenced and analyzed. The phylogenetic analysis based on 739 nucleotides showed that out of 57 Chinese rubella virus strains, 55 belong to a distinguish branch of 1E genotype when comparing with 1E genotype rubella strains from other countries, and the other 2 Chinese rubella virus strains belong to 2B genotype. Most of the nucleotide mutations of 57 rubella viruses were silent mutations, and the amino acid sequences were highly conserved. Except one amino acid change (Thr212 --> Ser212) in two rubella viruses at the hemagglutination inhibition and neutralization epitopes, there had no change found at the important antigenic epitope sites of the other rubella viruses. 1E genotype rubella viruses isolated from 10 provinces of China from 2003 to 2007, and two imported 2B genotype rubella viruses from Vietnam suggested that 1E genotype was the predominant genotype in this period of time. The rubella virus genotypes circulated during 2003 to 2007 were different from that circulating during 1979 to 1984 and 1999 to 2002, the rubella prevailed in recent years was mainly caused by 1E genotype rubella viruses with multi-transmission routes.

Abstract
AIM To investigate the relationship between solitary pulmonary nodules (SPN) and bronchi and its value in predicting the nature of the SPN. MATERIALS AND METHODS We performed volumetric targeted scans of 0.5 mm collimation with multi-slice computed tomography (MSCT), reconstructing multiplanar reconstructions (MPR), curved multiplanar reconstructions (CMPR) and surface-shaded display (SSD) images of bronchi in 78 consecutive patients with SPN (53 malignant and 25 benign) and correlated the findings with those of macroscopic and microscopic specimens. RESULTS With this CT protocol, the third to seventh-order bronchi were shown continuously and very clearly in all patients. CT findings were consistent with those of specimens. CT demonstrated the relationship between the SPN and bronchi in 46 (86.8%) malignant and 18 (75.0%) benign nodules. Five types of tumour-bronchus relationships were identified with MSCT. Type I: the bronchus was obstructed abruptly by the SPN; type II: the bronchus penetrated into the SPN with tapered narrowing and interruption; type III: the bronchial lumen shown within the SPN was patent and intact; type IV: the bronchus ran around the periphery of the SPN with intact lumen; type V: the bronchus was displaced, compressed and narrowed by the SPN. Malignant nodules were most commonly of type I (58.5%), secondly of type IV (26.4%) and rarely of type V (1.9%). Benign nodules were most often of type V (36.0%), followed by type III (20.0%), type I (16.0%), and there were no type II. Types I, II and IV were more common in malignant nodules, whereas type V was seen more frequently seen in benign nodules (p<0.05). There was no statistically significant difference between the two groups regarding type III. CONCLUSION Ultra-thin section with MSCT and MPR, CMPR and SSD reconstruction can improve the demonstration of the patterns of tumour-bronchus relationships, which can reflect the pathological changes of the nodules to some extent and help differentiate malignant from benign tumours.

Abstract
Electrophysiological and behavioral studies were performed in rat to investigate the changes of synaptic efficacy of the two inputs of hippocampal CA3 area [Mossy Fiber (MF) -CA3 and Perforant Path (PP) -CA3] during discrimination learning. The results showed that: (1) Amplitude of the population spike (PS) of both from MF-CA3 and PP-CA3 increased simultaneously with the establishment of conditioned response (CR) and both reached their maxima before CR reached the criterion of acquisition. (2) During natural extinction of CR, the amplitude of PS of both inputs decreased also simultaneously to their per-training level. These results indicated that the learning-dependent long-term potentiation (LTP) in both MF-CA3 and PP-CA3 inputs developed and extinguished synchronously, suggesting that the changes of synaptic efficacy of different inputs of hippocampal CA3 area coordinated during discrimination learning.

Abstract
The L1 spinal cord of 22 dogs were injured by modified Allen's method. During the interval of 50-100 days after injury, MR imaging were performed and the specimens of the injured spinal cord were taken out immediately for histological examination. T1 weighted images were used to observe changes of spinal cord signals. In 7 cases with cavity formation in the central part of the injured spinal cord was found histologically, there was small cavity in the spinal cord signal on MRI. In 12 cases with necrosis and softening in central area of the spinal cord, the T1 weighted image showed hypointensity in central part of spinal cord signal, and in 3 cases with necrosis, degeneration and glial replacement histologically, the MR image showed unhomogeneous and slight hyointensity signal. These entities suggested that the MRI appearances of spinal cord injury represented the histological changes of the spinal cord. Clinically, the MRI manifestation of 76 cases of old spinal cord injury were closely related to their neurologic deficiency. Cases of transection signal of spinal cord were excluded. There were six types of MRI appearances. In 40 cases of complete paraplegia, the MRI appearances were enlarged hypointensity signal in 16 hypointensity signal in 4, atrophy of the spinal cord in 13, large cavity in 3 and unhomogeneous with compression in 1. After treatment, there were no recovery in all cases. 36 cases of incomplete paraplegia their MRI showed normal signal but compressed in 16, all had good recovery after treatment. Unhomogenous signal with slight hypointensity was found in 11, they one frankle degree recovery after treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In the present study, the role of NE in learning-dependent long-term potentiation (LdLTP) was investigated by examining the effects of 6-hydroxydopamine (6-OHDA) lesion made in the bilateral dorsal noradrenergic bundle on the changes of synaptic efficacy in dentate gyrus (DG) and related conditioned response during drinking conditioning. Bilateral injection of 6-OHDA (12 micrograms/4 microliters) into the dorsal noradrenergic bundle caused a continuous decrease of the amplitude of population spike (PS) reaching a value of 50 +/- 6.3% and 28 +/- 6.4% respectively at the 6th and the 12th day after injection of the drug. During this period of 7 days, the LdLTP could not be produced in spite of 20 trainings per day for a total of 140 trials, and the conditioned drinking response could not be established. The above results indicate that normal levels of norepinephrine in the hippocampus are necessary to the establishment of LdLTP in the DG and suggest that the development of LdLTP in the DG may be modulated by the nucleus locus ceruleus via the dorsal noradrenergic bundle.

Abstract
The effect of microinjection of 2-amino-5-phosphonovaleric acid (APV), a selective NMDA receptor antagonist, into the rat hippocampal CA3 area on the synaptic efficacy and related conditioned behavior during the acquisition and consolidation of discrimination learning behavior was examined. The results showed: (1) After population spike (PS) amplitude had just increased to the maximum through training i.e. learning-dependent LTP had just formed, APV 1 microliter (2 mmol/L) was injected into CA3 area, then the rats were trained during the time of efficacy of the drug in every experimental block. The result demonstrated that the PS amplitude could not be maintained at the highest level but decreased to the pre-experiment level after 8 blocks. Correct response percentage of rats could not be consolidated with further training but decreased to less than 10%. (2) After the PS amplitude had kept up at the highest level, APV 1 microliter (2 mmol/L) was injected into CA3 area, then the rats were trained during the time of efficacy of the drug in every experimental block, in which case the PS amplitude also could not be maintained at the highest level but decreased to the pre-experiment level after 14 blocks. Correlatively, when the correct response percentage of rats decreased gradually to less than 10%, the conditioned response of the animals extinguished, but its extinction speed was slower than it was in result (1). These results suggest that the NMDA receptor in CA3 area plays an important role in the maintenance of the learning-dependent long-term potentiation.

Abstract
80 cases of intratrochaner fractures were treated by fixation of 4 Steinmann's pins which were 3.5 mm in diameter and inserted percutaneously through the calcar and compression trabeculae and distension trabeculae respectively. They were compared with the cases treated by skeletal traction or fixed by Nail-plate or angle plate. The rate of bony union in fixed position in the percalcar Steinmann's pins group was 83.7%. Normal neck-shaft angle accounted to 53.1% in the traction group. Varus deformity occurred in 16.3% cases of the Steinmann's pins group, and 35.9% cases of the traction group. The deformity was most frequently seen in cases of type IIIa and IV. No fixation failure occurred in the Steinmann's pins group. The Steinmann's pins passing through the outer cortex, calcar and compression trabeculae produced strong fixation and it's direction was in parallel to the weight-bearing line of the hip, with less shearing force and much compression force distributed on the fracture line. The operation was done under local anesthesia. No blood transfusion and early mobilization were the advantages of this method.

Abstract
From March 1989 to July 1990, Magnetic resonance imaging (MRI) examination was conducted in 60 patients with chronic injuries of the spine and the spinal cord, of whom 32 patients received exploration and decompression operation. Based on the results of MRI, clinical neurological examinations, biological electrical examinations were compared treatment. MRI proved to show the minute changes of the spine, the definite location of spinal compression, the narrowing of spinal canal and the actual cause of compression objects. Thus, it is helpful in selecting treatment and in predicting prognosis.

Abstract
A Type IIIa intertrochanteric fracture was made on the preserved femurs of adult cadavers. The fracture was fixed by 4 methods: Percalcar Steinmann's pins, Knowle's pins, Nail plate and Angle plate. The loading limit of the fixations were 150, 140, 70 and 40 kg respectively. In fatigue test the loading ability of the percalcar Steinmann's pins were 4 times greater than that of Nail plate or Angle plate. In Nail plate and Angle plate. The pathological section of the upper femur showed the most bony destruction was at the trabecula beneath the lateral cortex, and in the percalcar Steinmann's, it was at the neck trabecula, where the cal car plays an important role in supporting the loading of the lowest pin. It was found that the level arm was shortened and the loading ability increased. As the direction of the lowest pin was nearly parallel to the loading axis of the hip. The calcar suffered less shearing force. These findings showed that the percalcar Steinmann's pins fixation is the best in these 4 methods.

Abstract
The purpose of this study was to investigate the effects of microinjection of scopolamine, a M-cholinergic antagonist and picrotoxin, a GABA-ergic antagonist into the rat hippocampal CA3 area on the learning-dependent long-term potentiation (LDLTP) during the establishment, extinction and re-establishment of conditioned drinking response. Following stimulation of the perforant path, field potentials of hippocampal CA3 of freely moving rats were recorded. The results were as follows: the synaptic efficacy and the development of LDLTP in hippocampal CA3 were depressed significantly by scopolamine, but the extinction of LDLTP was accelerated. Picrotoxin significantly enhanced synaptic efficacy and facilitated the development of LDLTP, but it depressed the extinction of LDLTP. Meanwhile, the establishment or extinction of drinking conditioning was correspondingly depressed or accelerated. Moreover, the development of LDLTP and its extinction preceded the development and extinction of drinking conditioning. The results provide further evidence indicating that LDLTP might be one of the neuronal mechanisms underlying behavioral learning and memory. Moreover, it seems that M-cholinergic receptors and GABA-ergic receptors in rat hippocampal CA3 area are involved in the development and retention of LDLTP.
