Among 1 786 invasive primary lung cancers, 11 cases received preoperative neoadjuvant chemotherapy, and their postoperative pathologic diagnoses were stage ypIA. Other 1 775 cases who did not receive postoperative neoadjuvant treatment included 1 587 cases in stage ⅠA, 112 cases in stage ⅠB, 3 cases in stage ⅡA, 18 cases in stage ⅡB, 37 cases in stage ⅢA, 9 cases in stage ⅢB, 9 cases in stage Ⅳ. The average operation time was (127.3±55.3) minutes, and the mean postoperative hospital stay was (4.8±2.4) days. The incidence rate of complications (grade>2) was 1.1%(38/3 336), and no death occurred during 30 days after operation. Conclusion Anatomic partial lobectomy has good clinical applicability, safety and effectiveness, which is worthy of clinical application and recommendation.Objective To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer. Methods A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis. Results The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy (P less then 0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P less then 0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P less then 0.01). Conclusion Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.Objective To evaluate 5-years breast cancer-specific survival (CCS) by age, and the relationship of age at diagnosis and the risk of breast cancer mortality. Methods Medical records of 3 470 resident patients diagnosed with primary, invasive female breast cancer between January 1, 2006 and December 31, 2010 in four hospitals in Beijing were reviewed and collected. Acalabrutinib manufacturer All patients were followed up until December 31, 2018 to acquire survival outcome. Five-years breast CCS of the five subgroups was estimated by the life-table method. Cox proportional hazard regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of different levels of age stratification and breast cancer mortality, and restricted cubic spline (RCS) model was used to detect the dose-response relationship. Results The median diagnosis age among 3 470 female breast cancer patients was 53.2 years. There were 1 289 patients in the age-group of 45~54 years, with the highest proportion of 37.15%. However, only 126 pa of breast cancer mortality (nonlinear P less then 0.000 1). In addition, patients aged ≥65 years had significantly higher risk of breast cancer mortality in Luminal subtypes, with HR of 1.70 (95% CI 1.17~2.46) for Luminal A breast cancer and HR of 3.84 (95% CI 1.74~8.49) for Luminal B breast cancer. RCS analysis exhibited a non-linear ( "J-shaped" ) relationship between diagnosis age of female breast cancer and the risk of breast cancer mortality (nonlinear P less then 0.000 1). Conclusion Age at diagnosis is an important prognostic factor for female breast cancer, with worse outcome for both young and old patients.Objective To investigate the effect of pentraxin 3 (PTX3) on the proliferation, invasion and drug resistance of pediatric neuroblastoma cells and its mechanism. Methods si-RNA (si-RNA group), si-PTX3 (si-PTX3 group), siRNA+ pcDNA3.1 (siRNA+ pcDNA3.1 group), si-PTX3+ pcDNA3.1 (si-PTX3+ pcDNA3.1 group), siRNA+ pcDNA3.1-Toll-like receptor 4 (siRNA+ pcDNA3.1-TLR4 group) and si-PTX3+ pcDNA3.1-TLR4 (si-PTX3+ pcDNA3.1-TLR4 group) were transfected into SH-SY5Y cells. Collected 32 cases of tumor tissue and cancerous tissue in children with childhood neuromaternal cells who were treated at Zhumadian center hospital from July 2016 to August 2019. Real-time fluorescent quantitative polymerase chain (RT-qPCR) reaction and immunohistochemistry experiments were used to detect the protein expressions of PTX3 in neuroblastoma tissues and normal tissues. 5-Ethynyl-2'-deoxyuridine (EdU) was used to detect the proliferation effect of PTX3 on neuroblastoma cell SH-SY5Y. Western blot experiment was used to detect the protein expret can provide a new perspective for pediatric neuroblasts tumor diagnosis and clinical treatment.Objective To investigate the biological function of miR-758-3p and the underlying mechanism in non-small cell lung cancer (NSCLC). Methods miR-758-3p mimics was transfected to A549 NSCLC cells, miRNA control was used as a negative control, cells transfected with nucleolar and spindle associated protein 1 (NUSAP1)-overexpression vector indicated as NUSAP1 group, cells co-transfected with miR-758-3p mimics and NUSAP1-overexpression vector indicated as miR-758-3p mimics+ NUSAP1 group. The effects of miR-758-3p on the proliferation, migration and invasion abilities of A549 cells were detected by cell counting kit-8 (CCK-8) and Transwell assays, respectively. Bioinformatics and dual luciferase reporter assay were used to predict and verify the target gene of miR-758-3p. Results The expressions of miR-758-3p and NUSAP1 in A549 cells were significantly up-regulated at 24 hours after transfection with miR-758-3p mimics (P less then 0.05). Compared with the miRNA control group (1.15±0.06), the OD value of miR-758-3p mimic group (0.78±0.06) was significantly decreased at 72 hours after transfection (P less then 0.05). The number of migrated cells of miR-758-3p mimic group (119.04±11.49) was significantly lower than that of the control group (271.38±19.05) (P less then 0.05). The number of invaded cells of miR-758-3p mimic group (71.33±5.36) was significantly lower than the control group (164.30±8.11) (P less then 0.05). The result of dual-luciferase reporter assay showed that NUSAP1 was a direct target of miR-758-3p. Moreover, up-regulation of NUSAP1 abolished the inhibitory effects of miR-758-3p on the proliferation, migration and invasion abilities of A549 cells. Conclusion miR-758-3p inhibits the proliferation, migration and invasion of NSCLC cells by targeting NUSAP1.
