ABSTRACT

Objective@#To evaluate the occupational health risk of key posts exposed to cement dust in four cement production enterprises, and to provide reference for cement pneumoconiosis prevention and control. @*Methods@#Four Chinese typical cement enterprises and key posts exposed to cement dust were selected to carry out occupational health investigation and detection, and three risk assessment methods were used to assess their occupational health risk levels, including semi-quantitative comprehensive index method, semi-quantitative contact ratio method and risk rating method of International Mining and Metal Commission ( ICMM ). Meanwhile, the differences and consistencies among different assessment methods were compared. @*Results@#Dust free silica content ranged from ( 4.70±2.01 ) % to ( 5.63±2.48 ) %,and the total and respirable dust concentrations exposed by bagged cement loaders and cement baggers exceeded Chinese permissible concentration-time weighted average( PC-TWA ). The results of semi-quantitative comprehensive index method showed that all the types of work were at high risk of total and respirable dust, while the results of the other two assessment methods showed that bagged cement loaders and cement baggers were at a extremely high or intolerable risk. There were no significant differences among three risk assessment methods whether in terms of total dust or respirable dust ( P>0.05 ). ICMM risk rating method and contact ratio method showed highly positive correlation in term of respirable dust ( rs=0.894, P=0.016 ), but not in term of total dust ( rs=0.733, P=0.097 ). However, the correlations of comprehensive index method with the other two methods were unable to conduct.@*Conclusion@#Bagged cement loaders and cement baggers are at high occupational health risk levels. Moreover, semi-quantitative contact ratio method and ICMM risk rating method have high positive correlation in term of respirable dust, the applicability of comprehensive index method still needs further study.

ABSTRACT

Objective:To investigate the value of visfatin in the differential diagnosis of benign and malignant breast tumors and the feasibility of visfatin as a molecular marker of breast cancer.Methods:A total of 195 breast cancer patients hospitalized in the Cancer Hospital of The University of Chinese Academy of Sciences from December 2017 to July 2018 were selected as the breast cancer group, all of them were women. 80 patients with benign breast diseases in the same period were randomly selected as the breast benign disease group, all of them were women. 80 female employees with normal physical examination in the same year were selected as the normal control group. Enzyme linked immunosorbent assay (ELISA) was used to detect the serum level of visfatin. Logistic regression was used to analyze the relationship between visfatin and clinicopathological features of breast cancer. Receiver operating characteristic (ROC) curve was drawn to get area under curve (AUC) value, and the diagnostic efficacy was analyzed.Results:The serum visfatin level in breast cancer group was significantly higher than that in benign breast disease group and normal control group ( P<0.05). Univariate analysis showed that the serum visfatin level was related to lymph node metastasis, tumor node metastasis (TNM) stage and body mass index (BMI) (all P<0.05). The serum visfatin level was positively correlated with TNM stage and lymph node metastasis of breast cancer patients ( r=0.336, P=0.043; r=0.632, P=0.027, respectively). Multivariate regression analysis showed that lymph node metastasis was a risk factor for serum visfatin [ OR=1.098, 95% CI(1.073, 1.226), P=0.02]. According to the ROC curve of serum visfatin level in benign breast disease group and normal group, the AUC of serum visfatin were 0.652 and 0.701, respectively. When the Youden index was the highest, the sensitivity was 52.30% and 55.90% respectively, and the specificity was 73.10% and 75.0% respectively. Conclusions:Serum visfatin level can be used to distinguish benign and malignant breast cancer patients. It has a certain clinical value in the auxiliary diagnosis of breast cancer, and may be used as a potential molecular marker of breast cancer.

ABSTRACT

The purpose of this study was to investigate the anti-cancer effect of melittin on growth, migration, invasion, and apoptosis of non-small-cell lung cancer (NSCLC) cells. This study also explored the potential anti-cancer mechanism of melittin in NSCLC cells. The results demonstrated that melittin suppressed growth, migration, and invasion, and induced apoptosis of NSCLC cells in vitro. Melittin increased pro-apoptotic caspase-3 and Apaf-1 gene expression. Melittin inhibited tumor growth factor (TGF)-β expression and phosphorylated ERK/total ERK (pERK/tERK) in NSCLC cells. However, TGF-β overexpression (pTGF-β) abolished melittin-decreased TGF-β expression and pERK/tERK in NSCLC cells. Treatment with melittin suppressed tumor growth and prolonged mouse survival during the 120-day observation in vivo. Treatment with melittin increased TUNEL-positive cells and decreased expression levels of TGF-β and ERK in tumor tissue compared to the control group. In conclusion, the findings of this study indicated that melittin inhibited growth, migration, and invasion, and induced apoptosis of NSCLC cells through down-regulation of TGF-β-mediated ERK signaling pathway, suggesting melittin may be a promising anti-cancer agent for NSCLC therapy.

ABSTRACT

Objective To clarify the role of human β-defensin2 ( hBD2) on preventing oxidized low-density lipoprotein (OX-LDL) induced human leukemic monocyte (THP-1) foaming.Methods The monocyte foaming model was established using THP-1 cell induced by OX-LDL and the model was identified by oil red staining.The hBD2 was overexpressed on THP-1 cells by using lentivirus system and the effect of hBD 2 overexpression on THP-1 cell foaming induced by OX-LDL was detected.The levels of inflammatory factors including tumor necrosis factor (TNF)-α, interleukin (IL)-1βand IL-6 in cell supernatant of each group were detected by enzyme-linked immunosorbent assay ( ELISA).Differences between the groups were compared by using the t test.Results The gene transfection efficiency of the cells was close to 100%at 72 h after infection. The hBD2 protein levels were 0.122 ±0.024 in the control group, 0.123 ±0.022 in Lv-control infection group and 0.981 ±0.183 in Lv-hBD2 infection group; and the level in control group was statistically higher than that in hBD-2 infection group (t=-3.175, P=0.007).The relative levels of hBD2 mRNA at 72 h after virus infection were 0.131 ±0.021 in control group, 0.128 ±0.022 in Lv-control group and 1.001 ±0.105 in Lv-hBD2 infection group; and the level in control group was statistically higher than that in hBD-2 infection group (t=-7.213, P=0.003).The results of oil red staining showed that OX-LDL inducing THP-1 cells for 72 h could significantly induce lipid accumulation in cells.Overexpression of hBD2 could effectively inhibit lipid accumulation in THP-1 cells induced by OX-LDL.The expression of hBD2 mRNA in THP-1 group was significantly higher than that in THP-1+OX-LDL group (t=3.237, P=0.004); and the difference was also significant when comparing THP-1+Lv-hBD2+OX-LDL group with THP-1+OX-LDL group (t=-6.021, P=0.003).The level of hBD2 protein in THP-1 group was significantly higher than that in THP-1+OX-LDL group (t=0.314, P=0.006); and the difference was also significant when comparing THP-1+Lv-hBD2+OX-LDL group with THP-1+OX-LDL group (t=-4.061,P=0.007).The levels of TNF-α, IL-1βand IL-6 in the supernatant of THP-1 cells induced by OX-LDL for 72 h were significantly increased compared with those in THP-1group (t=-3.825,-2.017 and -3.551, respectively; P=0.007, 0.004 and 0.005, respectively). The levels of TNF-α, IL-1βand IL-6 in THP-1+Lv-hBD2+OX-LDL group were significantly lower than those in THP-1+OX-LDL group ( t=4.132, 3.681, and 2.991, respectively; P=0.003, 0.002, and 0.007, respectively).Conclusions hBD2 can effectively inhibit THP-1 foaming induced by OX-LDL, which may be related to its inhibition of inflammatory response.

ABSTRACT

Objective@#To explore the apoptosis-inducing effect of the Chinese medicinal compound CFF-1 on prostate cancer cells and its related molecular mechanisms.@*METHODS@#Normal prostate WPMY-1 cells and prostate cancer LNCaP, CWR22Rv1, PC3 and DU145 cells were treated in dehydrated alcohol with CFF-1 at 0, 2, 5, or 10 mg/ml for 24 hours. Then the viability of the prostate cells was detected by morphological observation, MTT and CCK-8 assay, nuclear condensation and disruption measured by DAPI staining, the cell cycle and apoptosis calculated by flow cytometry, the activity of the PI3K/AKT/FOXO1 signaling pathway and the expressions of its downstream apoptosis- and cycle-related proteins determined by Western blot.@*RESULTS@#CFF-1 significantly arrested the cell cycle in the G1 phase, decreased the cell viability and increased the nuclear condensation and disruption in a dose-dependent manner, and elevated the apoptosis rate of prostate cancer cells. At the molecular level, CFF-1 dose-dependently reduced the activity of the PI3K/AKT signaling pathway and phosphorylation of the FOXO1 protein, increased the transcription activity of FOXO1, and eventually regulated the expressions of cell apoptosis- and cycle-related genes.@*CONCLUSIONS@#The Chinese medicinal compound CFF-1 can significantly inhibit the growth, arrest the cycle, and induce the apoptosis of prostate cancer cells by decreasing the activity of the PI3K/AKT/FOXO1 signaling pathway, which suggests its potential clinical application value in the treatment of prostate cancer.

ABSTRACT

Aim To research the effects of HSP70 in-hibitor ( PFTμ) on the expressions of iNOS induced by IFN-γ in RAW 264. 7 cells. Methods The NO con-centration was measured by Griess Kit. The expression of interest protein was measured by Western blot and iNOS mRNA was measured by RT-PCR. Mouse cardi-ac ischemia-reperfusion ( I/R ) model was established to set up the inflammatory response. These were divid-ed into control and treated groups. The infarct size was monitored on myocardial I/R mice. Results We found that PFTμsignificantly blocked the production of NO and the expression of iNOS protein and mRNA in RAW 264. 7 cells. The mechanism may be part of the inhibition of nuclear IRF-1 protein expression. We also found that PFTμ reduced the infarct size in myocardial I/R mice ( P <0. 05 ) . Conclusion These results suggest that PFTμ down-regulates the IFN-γ-induced iNOS transcription through decreasing translocated IRF-1 protein.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the efficacy and safety of 3 rivaroxaban regimen in patients with venous thromboembolism (VTE).</p><p><b>METHODS</b>This is a retrospective study. Thirty three inpatients with VTE received rivaroxaban were divided into 3 groups, in which 16 patients were treated with 15 mg rivaroxaban twice daily for 21 days then followed by 20 mg once per day till 3 months (group 1), 9 patients were treated with 20 mg rivaroxaban once daily for 3 months (group 2), 8 patients were treated with 10 mg rivaroxaban once daily for 3 months. The reduction rate of D-Dimer on the third therapy day, the duration of D-Dimer normalization and hospital stay as well as symptom remission, the imaging assessment results after three months treatment, rate of recurrent VTE, bleeding, liver and kidney function were compared among the 3 groups.</p><p><b>RESULTS</b>The reduction rates of D-Dimer on the third therapy day were significantly higher ((46.12 ± 15.42) % vs. (26.59 ± 8.11) % and (25.55 ± 14.00) %, P = 0.02, P = 0.01), and the duration of D-Dimer normalization was significantly shorter ((17.9 ± 7.7) days vs. (24.1 ± 5.1) days and (26.3 ± 6.2) d, P = 0.03, P < 0.01) in group 1 than in group 2 and 3. There was one recurrent deep-vein thrombosis in group 3, one non-major bleeding in group 1 and group 3. Major bleeding or liver and kidney dysfunction were not observed in these patients.</p><p><b>CONCLUSIONS</b>Venous thromboembolism can be safely and effectively treated by rivaroxaban, and does of 15 mg twice daily for 21 days followed by 20 mg once daily for 3 months are superior to the other 2 tested therapy regimen in this patient cohort.</p>

ABSTRACT

Chongqing Medical University selected some five-year clinical medical undergradu-ates to set up the pilot class which was called 'clinician excellent class' and implemented the 'organ-systems-based curriculum' (OSBC) integration teaching reform on them. The OSBC teaching of the cardiovascular system breaks the traditional pattern, and carries on the comprehensive reorganization to the curriculum contents and the teaching personnel, and emphasizes the collective preparation, the new teaching method and the reasonable evaluation system. Although OSBC teaching of the cardiovas-cular system has made some achievements, but there are still many deficiencies need to reflect on and improve.
