Methods This cross-sectional study enrolled 91 Chinese postoperative breast cancer patients aged 35 years or younger. The depression and anxiety state of patients were assessed by Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 (GAD-7), and their sociodemographic characteristics were collected. Results Among the 91 patients, 61 were receiving ovarian function suppression (OFS) treatment, 30 were not. Among the 30 patients with out OFS treatment, 2 had PHQ-9 score ≥8, 28 had PHQ-9 score less then 8, 1 had GAD-7 score ≥10, and 29 had GAD-7 score less then 10. Among the 61 patients with OFS, 19 had PHQ-9 score ≥8, 42 had PHQ-9 score less then 8, 8 had GAD-7 score ≥10, and 53 had GAD-7 score less then 10. The incidence of depression was 6.7% and 31.1% in the non-OFS group and OFS group, respectively (P=0.018). Selleckchem 3-O-Acetyl-11-keto-β-boswellic The incidence of anxiety in the two groups was 3.3% and 13.1%, respectively (P=0.174). Univariate analysis showed that the incidence of depression was significantly higher in patients with OFS (P=0.018). After taking into account the sociodemographic factors, pathological stage and treatment of the patients, multivariate analysis showed that the administration of OFS was still significantly related to the incidence of depression (OR=9.14, 95% CI=1.52~55.16, P=0.016). There was no significant difference in the incidence of anxiety (P=0.174). Conclusions For Chinese young breast cancer patients under 35 years old, the use of OFS in the adjuvant endocrine therapy may lead to a significant increase in the incidence of depression. We should pay attention to the evaluation and monitoring of the psychological state of this population.Objective To analyze the metabolism of blood glucose and lipid in breast cancer patients after the first chemotherapy. Methods Breast cancer patients who received chemotherapy for the first time from December 2016 to January 2020 were collected in our hospital, and their blood glucose and lipid levels were monitored. Patients were grouped according to different treatment plans. Non-parametric rank sum test was used for statistical analysis on SPSS software. Results There were 1 356 female breast cancer patients were enrolled, blood glucose and lipid levels were compared before and after chemotherapy. Our results showed that baseline medium blood glucose was 5.2 mmol/L, lower than 5.3 mmol/L after chemotherapy (P less then 0.05). The baseline triglyceride (TG) was 1.2 mmol/L, lower than 1.6 mmol/L after chemotherapy (P less then 0.05). The baseline small dense low-density lipoprotein (sdLDL) was 0.7 mmol/L, lower than 0.8 mmol/L after chemotherapy (P less then 0.05). The baseline high density lipoprotein (HDL) was 1.3 mmol/L, higher than 1.2 mmol/L after chemotherapy (P less then 0.05). Patients' menstrual status and body mass index were related with blood glucose, TG, LDL and sdLDL (all P less then 0.05). Conclusions Abnormal metabolism of blood glucose and lipid are observed in breast cancer patients after the first chemotherapy. More awareness of cardiovascular disease in breast cancer patients might ensure their overall clinical benefits.Objective To explore the clinical characteristics, therapeutic methods and prognosis of pleuropulmonary blastoma in children. Methods The clinical data of 28 patients with pleuropulmonary blastoma diagnosed in Guangzhou Women and Children's Medical Centre from November 2008 to May 2018 were collected and retrospectively analyzed. Results Of the 28 patients, 18 were male and 10 were female, aged from 22 days to 5 years 10 month, the average age was 2 years 6 months. One patient underwent biopsy and other 27 underwent operation, 14 patients with type Ⅱ/Ⅲ pleuropulmonary blastoma received postoperative chemotherapy. Five patients were pathologically diagnosed as typeⅠpleuropulmonary blastoma, 5 were type Ⅱ pleuropulmonary blastoma and 18 were type Ⅲ pleuropulmonary blastoma. During the follow-up period of 24 patients, 15 patients were disease free survival, 3 patients relapsed within 6 months, 10 months and 18 months after chemotherapy, respectively. One patient who received postoperative chemotherapy suffered a bone metastasis within 11 months, 2 patient without chemotherapy relapsed within 2 months and suffered bone or renal metastasis within 3 months, respectively. Three patients who left hospital voluntarily died within 1 month. Conclusions Pleuropulmonary blastoma is a highly malignant and rapidly progressed neoplasm. Patients with type Ⅰ pleuropulmonary blastoma have good prognoses while the prognoses of Ⅱ/Ⅲ pleuropulmonary blastoma are poor. Postoperative chemotherapy seems to improve the survival of patients withⅡ/Ⅲ pleuropulmonary blastoma.Objective To study the effects of Tectoridin on the proliferation, migration and invasion of ovarian cancer SK-OV-3 cells and its mechanism. Methods SK-OV-3 cells were treated with 0, 5, 10, 50 and 100 μg/L Tectoridin for 24 hours. The proliferation of SK-OV-3 cells treated with different concentrations of Tectoridin was detected by cell counting kit-8 (CCK-8). The migration was analyzed by wound healing test and the invasion was observed by Transwell.

The relative migration distances of the cells were 1.000±0.083, 0.896±0.092, 0.644±0.075, 0.432±0.056, and 0.215±0.043, respectively. The numbers of cell invasion were (106.258±11.785), (93.241±10.251), (74.258±7.963)toridin may inhibit proliferation, migration and invasion of SK-OV-3 cells by regulating PI3K/AKT signaling pathway.Objective To investigate the effect of miR-148b-3p on invasion and migration of glioma cells and the possible molecular mechanism. Methods Human glioma U251 cells were cultures in vitro. MiR-148b-3p mimic or negative control was transfected into U251 cells by Lipofectamine 2000 transfection reagent, which were recorded as miR-148b-3p group and NC group, respectively. A blank control (Ctr group) was set. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the transfection effect. Transwell assay was used to detect the invasive ability of U251 cells in each group. The scratch test was used to detect the migration ability of U251 cells in each group. The concentrations of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in the supernatant of the cells were determined by enzyme-linked immunosorbent assay (ELISA). Western blot was used to detect the expressions of Wnt signaling pathway-related proteins in cells. Results The qRT-PCR experiment showed that the expression level of miR-148b-3p in U251 cells of miR-148b-3p group (2.45±0.25) was significantly higher than that of NC group (0.97±0.10) and Ctr group (1.00±0.11) (P less then 0.05). Transwell and scratch experiments showed that the number of invasive cells (50.62±5.36) in miR-148b-3p group was significantly lower than those in NC group (108.84±10.14) and Ctr group (113.40±10.06) (P less then 0.05). The results of the scratch experiment showed that the cell migration rate of miR-148b-3p group (23.19±2.50)% was significantly lower than those of NC group (51.81±5.25)% and Ctr group (52.06±5.33)% (P less then 0.05). Overexpression of miR-148b-3p inhibited the expressions of MMP-2 and MMP-9, downregulated the expressions of Wnt1 and GSK-3β protein. Conclusion miR-148b-3p can inhibit the invasion and migration of human glioma U251 cells by inhibiting the activation of Wnt signaling pathway.Objective To investigate the effects of microRNA-451 on proliferation, invasion and migration of multiple myeloma RPMI-8226 cells and its mechanism. Methods RPMI-8226 cells cultured in vitro were divided into blank control group (untransfected), negative control (NC) group and miR-451 mimic transfected (miR-451) group. The expression of miR-451 was detected by real-time quantitative PCR (qRT-PCR), cell proliferation was detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) array and clone formation experiment, cell invasion and migration were detected by Transwell, and the expressions of c-Myc, MMP-2 and MMP-9 proteins were detected by western blot. The targeting relationship between miR-451 and c-Myc was detected by double luciferase reporter gene assay. Results Compared to the blank control group, the expression level of miR-451 was increased (2.85±0.27 vs 1.02±0.06), while the cell survival rate [(47.28±3.15)% vs (93.65±6.52)%], cloning formation rate [(15.03±1.34)% vs (28.48±2.12)%], invasive cell number (86.65±5.58 vs 135.47±9.85), migrating cell number (106.36±6.48 vs 165.28±11.05) and the expression level of c-Myc(0.35±0.03 vs 0.66±0.05), MMP-2 (0.20±0.02 vs 0.48±0.03) and MMP-9 (0.28±0.03 vs 0.59±0.06) protein were significantly decreased in the miR-451 group (P0.05). Double luciferase reporter gene experiment confirmed that c-Myc was a potential target gene of miR-451. Conclusion miR-451 can inhibit the proliferation, invasion and migration of RPMI-8226 cells by targeting c-Myc.Objective To investigate the effects of miR-141-3p on proliferation and migration of gastric cancer cells and nuclear factor-κB (NF-κB) signaling pathway. Methods Human gastric cancer cell line BGC-823 was cultured, and miR-141-3p mimetic (miR-141-3p mimics) was transfected into BGC-823 cells by lipofection. The miR-141-3p overexpressed BGC was constructed. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the transfection effect. The proliferation of BGC-823 cells was determined by 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Transwell assay was used to detect the effect of miR-141-3p on BGC-823 cell migration. The expressions of NF-κB p65, p-IKK-α and p-IKB-α protein in NF-κB signaling pathway were detected by western blot. Results Compared with the control group and the negative control group, the expression level of miR-141-3p in BGC-823 cells of the miR-141-3p group was (2.39±0.27), which was higher than (1.00±0.09) of the control group and (1.01±0.10) of the negative control group (P less then 0.05). The number of migrating cells in the miR-141-3p group was (47.64±5.65), which was lower than (106.22±12.14) in the control group and (110.40±12.26) in the negative control group (P less then 0.05). The expression levels of NF-κB p65, p-IKK-α and p-IKB-α protein in BGC-823 cells were down-regulated (P less then 0.05). Conclusion MiR-141-3p can inhibit the proliferation and migration of human gastric cancer BGC-823 cells, which may be related to the inhibition of NF-κB signaling pathway activation.
