Purpose To explore the pathological feature of urinary exfoliated cell examination and influence factors by retrospectively comparing the coincidence of diagnosis between urinary exfoliated cell examination and histopathologic results of cystoscopic biopsy. Methods 735 patients underwent both urinary exfoliated cell examination and histopathologic biopsy of cystoscope evaluation from No-vember 2010 to July 2014 in Peking University Shougang Hospital were enrolled in this study. The urinary exfoliated cells were treated with Pap staining, while the histopathologic biopsy were dealt with HE staining. All cases were divided into three groups according to the diagnosis of urinary exfoliated cell examination:negative group ( no cancer or atypical cell detected) , suspicious group ( atypical cell detected) and positive group ( cancer cell detected) . These above diagnoses were confirmed with the histopathologic biopsy. ROC curve analysis, Cochran-Armitage trend test and logistic regression analysis were performed to evaluate the sensitivity and the specificity of urinary exfoliated cell examination as well as the relationship between diagnoses with age and sex. Results The age range of 735 patients (551 male and 184 female) was 28 ~91 years and the median age was 69 years. There were 187 patients in the positive group, including 184 malignant and 3 false-positive cases. The suspicious group, including 186 cases, consisted of 67 malignant, 119 benign reactive changes. Of all 362 cases in the negative group, malignant tumor was detected in 90 cases. For histologic diagnosis, the AUC of ROC(95%CI)was 0. 800 (0. 767~0. 834), displaying significant difference as compared to the histological pathological diagnostic results(P<0. 001). As the cyto-histologic diagnostic level elevated from negative, suspicious to positive, the results of Co-chran-Armitage trend test showed significant differences(Z=15. 83, P<0. 001). If standardized with the histopathologic biopsy re-sults, the AUC (area under curve) of urinary exfoliated cell examination was 0. 800 (0. 767~0. 834) in ROC curve analysis was sig-nificantly larger (P<0. 001). Furthermore, we also found in Logistic regression that the incidence of cancer was 1. 04 (1. 03~1. 05) times higher if aged one year older ( P<0. 001 ) , while there was no significant relationship between the incidence and the sex ( P=0. 655). Conclusions The coincidence rate of urinary exfoliated cell examination increases with the malignant degree. A positive cor-relation is detected between age and the incidence of malignant tumor. Detailed clinical material can markedly improve the sensitivity and accuracy of cyto-histologic diagnosis.

Objective To investigate the regeneration and differentiation of HOCs in the 2-AAF/PHx rat models. To explore the expression of Cyr61and its mechanism in differentiation of HOCs in vitro. Methods In 2-AAF/PHx rats model,induction and expansion of HOCs were detected by immunochemistry and HE staining. West-ern blot was used for observing the expression of Cyr61. Furthermore,the expression of Cyr61 andβ-catenin were detected by Western blot in differentiation of WB-F344 cells in vitro. Results Cyr61 protein level increased as a re-sult of HOCs in rats livers after 2-AAF/PHx. In addition,the expression of Cyr61 and β-catenin significantly in-creased during WB-F344 cells differentiation in vitro. Conclusions Cyr61 might play an important role as a signal-ing mediator in HOCs response and closely correlate with Cyr61 andβ-catenin in proliferation and differentiation of HOCs.

Objective To retrospectively analyze the relationship between progression free survival (PFS) and overall survival (OS) in patients with non small cell lung cancer (NSCLC), and to detect the influence of plasma fibrinogen and D-dimer levels before treatment in the prognosis of advanced stage (stageⅢB-Ⅳ) of NSCLC. Methods The study comprised 134 NSCLC patients with clear pathological diagnosis. All patients were grouped by plasma fibrinogen and D-dimer levels before treatment. We set the normal values of fibrinogen as≤4 g/L and D-dimer as≤500μg/L(FEU). Patients with normal levels of fibrinogen and D-dimer were grouped into low risk group, patients with elevated fibrinogen or D-dimer were grouped into median risk group, and patients with both elevated values were grouped into high risk group. Chi-square test and one way ANOVA analysis were used to analyze the clinicopathologic features of different groups. The OS and PFS in different groups were analyzed by Kaplan-Meier analysis. Univariate analysis of PFS and OS were conducted. Then multivariate analysis was conducted with the Cox regression model in three groups. Results The clinicopathologic features showed no differences between different groups. There were significant differences in OS and PFS between high risk group and other groups. In the survival curves, the high risk group showed poor prognosis. The result of multivariate analysis showed that clinical stage (OS:RR=1.846, 95%CI 1.150-2.964,P=0.011; PFS:RR=1.762, 95%CI 1.190-2.609, P=0.005) and grouped by fibrinogen and D-dimer (OS:RR=1.415,95%CI 1.050-1.908,P=0.023;PFS:RR=1.373,95%CI 1.070-1.761,P=0.013) were prognostic factors for patients with NSCLC. Conclusion The plasma fibrinogen and D-dimer levels before treatment are closely related with the prognosis of NSCLC patients. And a high plasma fibrinogen and D-dimer levels before treatment are associated with poor prognosis in advanced stage of NSCLC patients.

Currently, postoperative adjuvant chemotherapy is recommended for patients with stageⅡ-ⅢA non-small cell lung cancer (NSCLC). However, the toxicity of chemotherapy should not be neglected, despite the survival benefits achieved. There is an urgent need for new, effective, individualized treatment regimens with low toxicity. EGFR-TKI is widely used for the treatment of advanced NSCLC because of its high efficiency and low toxicity. To explore more effective treatment methodologies, researchers at home and abroad have made many attempts to extend targeted therapy to the field of postoperative adjuvant therapy. This article reviews the retrospective and prospective clinical studies that have been conducted, analyzes the preponderant population of postoperative adju-vant targeted therapy, and seeks evidence-based medical evidence to guide clinical practice, so that patients with NSCLC can benefit from targeted therapies and improved postoperative survival rates.

Lung cancer is the most common malignant tumor in the world. In order to improve the survival rate of patients with advanced lung cancer, more effective treatment methods are needed,in which immunotherapy has a broad therapeutic prospect. In recent years, immune-checkpoint inhibitors have received extensive attention in the treatment of lung cancer. Significant progress has been made in the development of a variety of first-line and second-line treatments, and significant advances have been made in the treatment of advanced lung cancer. With the successful application of immune-checkpoint inhibitors, neoadjuvant therapy has attracted extensive attention. In addition, the successful application of combined therapies such as immune combined immunization, immune combined tyrosine kinase inhibitor (TKI) and immune combined chemotherapy improved the survival rate of patients to some extent. However, pseudo progression and drug resistance has become a non-negligible problem in the immunotherapy of non-small cell lung cancer, which is worthy of further study. Although immune-checkpoint inhibitors have once again brought attention to tumor immunotherapy, their side effects are also worthy of attention. The recent advances in the application of immune-checkpoint inhibitors in lung cancer were summarized in order to provide a theoretical basis for its clinical application.

OBJECTIVETo study the clinicopathologic characteristics of IgG4-related sialodacryoadenitis and chronic rhinosinusitis (CRS).

METHODSA total of 13 patients (patient group) were evaluated clinically and biopsy specimens from the lacrimal/salivary glands (n=12) and nasal mucosa (n=8) were reviewed and immunohistochemistry was performed to assess IgG-and IgG4-positive cells. Similarly, nine patients with IgG4-related sialodacryoadenitis without CRS and 10 patients with common CRS were included as controls.

RESULTSThere were 8 male patients and 5 female patients. The age of patients ranged from 32 to 71 years (mean 50.2 years). The patient group had higher serum IgG4 concentration than that of the control group (P<0.05). Lymphoplasmacytic infiltration, lymphoid follicle formation and sclerosis were prominent in lacrimal/salivary glands in both groups; however the magnitude of IgG4-positive plasmacytic infiltration in the patient group was significantly higher than that of the control group (P<0.05). Similarly, evaluation of nasal mucosa revealed greater lymphocytic and plasmacytic infiltration, and lymphoid follicle formation, together with significantly higher amount of IgG4-positive plasma cell infiltration in the patient group compared to the common CRS group (P<0.05).

CONCLUSIONSIgG4-related disease (IgG4-RD) simultaneously involving lacrimal/salivary glands and nasal cavity/paranasal sinuses is rare and characterized by a combination of IgG4-positive plasma cell infiltration involving lacrimal/salivary glands and nasal mucosa along with an increased serum level of IgG4. As a systemic disease, early and accurate diagnosis is therefore of great importance, and unnecessary surgery should be avoided.

OBJECTIVETo investigate the effect of complete resection standards on the prognosis of non-small cell lung cancer.

METHODSClinical data of 2 711 inpatient cases treated from January 2000 to December 2008 at our hospital were retrospectively reviewed. The relationship between surgical resection standard and the overall survival and other factors affecting the overall survival was analyzed.

RESULTSThe overall 5-year survival rate was 44.6%. The overall 5-year survival rate of stage IA, IB, IIA, IIB, IIIA cases was 60.5%, 55.4%, 43.1%, 37.0% and 28.1%, respectively. The 5-year survival rate of patients who underwent complete resection was 50.3%, and that of patients who underwent incomplete resection was only 40.1% (P < 0.01). The main prognostic factors were operation type, resection margin, pathological type, T stage, N stage, TNM stage, the number of dissected lymph node (LN) stations (<6 and ≥ 6), the number of resected lymph nodes (1-10, 11-20, and >20), postoperative radiotherapy and complete resection (P < 0.05 for all). Cox regression suggested that TNM stage and complete resection were independent factors affecting the prognosis. Adjuvant chemotherapy affected the prognosis of stage II-IIIA patients.

CONCLUSIONSTNM stage and complete resection are independent factors affecting the prognosis of NSCLC patients. The 5-year survival rate of NSCLC has significantly increased through promoting the standard of operation, especially increasing the standard of lymph node dissection. The standard of complete resection should be recommended to be used in clinical practice. Adjuvant chemotherapy is beneficial for stage II-IIIA NSCLC patients.
