Objective To assess the prognostic significance of pre-treatment hypercoagulable state in cervical cancer patients. Methods With retrospective analysis, pre-treatment coagulation indicators and platelets from 321 cervical cancer patients from stages I to IV were collected. The pre-treatment coagulation parameters were investigated along with tumor stage and survival data. Result Advanced tumor stage was associated with elevated fibrinogen (Fbg) and platelet (PLT) levels (P < 0.05). Patients with higher levels of Fgb, PTA and PLT suffered from higher risk of recurrence (P<0.05). Multivariate survival analyses showed that tumor stage, Fgb and PTA were independent prognostic factors for disease free survival. Conclusion Coagulation parameters can be served as useful tool for predicting recurrence of cervical cancer.

OBJECTIVETo investigate the mechanism underlying the inhibitory effect of STOML-2 overexpression on apoptosis of human cervical squamous carcinoma Siha cells.

METHODSSiha cells were transfected with an adenoviral vector carrying STOML-2, and 72 h later STOML-2 expression and the proliferation of the cells were detected by Western blotting and MTT assay. The transfected cells were treated with IC50 Cisplatin for 24 h, and the morphological changes of cells were observed using fluorescence, and the cell apoptosis was analyzed using flow cytomerty; the expression levels of proteins related with mitochondrial apoptosis pathway, including caspase-3, cleaved caspase-3, Bcl-2, Bax and cytochrome C (Cyt C), were detected by Western blotting.

RESULTSWestern blotting showed a significantly increased STOML-2 expression in the transfected cells. Overexpression of STOML-2 obviously promoted the proliferation of Siha cells. The STOML-2-overexpressing cells exhibited an obvious resistance to IC50 Cisplatin-induced apoptosis as shown by both fluorescence microscopy and flow cytometry and presented with decreased expressions of cleaved caspase-3, Bax, and cytosol Cyt C and increased expressions of caspase-3, Bcl-2, and mitochondrial Cyt C.

CONCLUSIONSOverexpression of STOML-2 can enhance the proliferation of Siha cells by inhibiting cell apoptosis possibly through the mitochondrial apoptosis pathway.

OBJECTIVE:To investigate the situation and influential factors of hospital pharmacist career planning and career satisfaction and their relationship. METHODS:The questionnaire modified according to"general career planning and career satisfaction scale"was adopted for questionnaire survey among pharmacists in 5 third grade class A hospitals by simple random sampling. The factor analysis was used to test the reliability and validity of the questionnaire. The influential factors of career planning and satisfaction degree,the relationship of career planning with satisfaction degree were analyzed by multiple regression analysis and Spearman correlation coefficient. RESULTS:Totally 210 questionnaires were sent out and 198 were effectively received,with effective recovery of 94.28%. Cronbach'α value of reliability and validity test was 0.939(>0.6),and KMO value was 0.905(close to 1). Results of survey showed that there was statistical significance in the effects of gender,age,marital status, work experience,professional title and position on career planning(P<0.05). There was statistical significance in the effects of age and professional title on satisfaction degree(P<0.05). Different dimensions of career planning(self-assessment,career awareness and action,position questions)were positively correlated with career satisfaction degree(total correlation coefficients were 0.649,0.633,0.694). CONCLUSIONS:Career planning is mainly influenced by gender,age,marital status,work experience,professional title and position. Career satisfaction degree is greatly influenced by age and position.The better the career planning is,the higher the satisfaction is. It is suggested to conduct professional training of hospital pharmacists by referring to the theory and experience of management,help pharmacists to fully understand the job responsibilities and do a good job in the position of professional roles. The establishment of scientific and effective career planning management system improves self-management ability of hospital pharmacists and career satisfaction degree,and promotes the development of discipline.

Objective:To investigate the effects of osimertinib on proliferation, migration and invasion of procollagen-lysine 2-oxoglutarate 5-dioxygenase 2 (PLOD2) overexpressing HCC827 cells and explore the potential mechanism of PLOD2 induced osimertinib resistance.Methods:We transfected HCC827 cells with LV-vector and LV-over/PLOD2. The expression of PLOD2 was detected by quantitative real time polymerase chain reaction (qRT-PCR) and western blotting. The effects of osimertinib on the proliferation of HCC827-vector and HCC827-PLOD2 cells were evaluated by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT) assay. The effects of osimertinib on the migration and invasion of HCC827-vector and HCC827-PLOD2 cells were determined by Transwell assays. The expressions of E-cadherin and vimentin in cells were detected by immunofluorescence (IF). The expressions of epithelial-mesenchymal transition (EMT), FAK-PI3K/AKT and MAPK signal pathway related proteins were detected by western blotting.Results:The MTT assay showed that HCC827-PLOD2 cells were hyposensitive to osimertinib. The 50% inhibitory concentration (IC 50) and resistance index of osimertinib for HCC827-PLOD2 cells was over 1 000 nmol/L and over 100, respectively. The result of wound healing assay showed that the migration distance of HCC827-PLOD2 was about (2.13±0.21) fold changes as that of HCC827-vector cells. The result of Transwell assay showed that the numbers of HCC827-PLOD2 passing through the matrix membrane were (212.78±10.43), significantly higher than (101.32±12.52) of HCC827-vector cells ( P<0.01). The result of IF showed that compared with HCC827-vector cells, the expression of E-cadherin was down-regulated while vimentin was up-regulated in HCC827-PLOD2 cells. Osimertinb downregulated E-cadherin and upregulated vimentin expression in HCC827-vector cells but had limited effect in HCC827-PLOD2 cells. The result of western blotting showed that PLOD2 significantly increased vimentin expression level while decreased E-cadherin expression level. Osimertinib inhibited the expression of p-EGFR, but did not affect the expressions of PLOD2, p-FAK, p-AKT, p-ERK, vimentin and E-cadherin in HCC827-PLOD2 cells. Conclusion:PLOD2 confers resistance to osimertinib in HCC827 cells by regulating EMT, FAK-PI3K/AKT and MAPK signal pathways.

Objective To test the effect of metastasis associated in lung adenocarcinoma transcript 1 ( MALAT1) and／or osimertinib on the proliferation and apoptosis of HCC827 cells, and explore the potential mechanism of MALAT1 induced resistance to osimertinib. Methods We transfected HCC827 cells with LV?vector or LV?over／MALAT1. Stable transfected cells ( HCC827／Vector, HCC827／MALAT1) were selected by adding puromycin. HCC827／MALAT1 cells were further transfected with the shRNA?negative control ( NC) or shRNA?human epidermal growth factor receptor 3 ( ERBB3 ) plasmid. The effects of overexpression of MALAT1, knockdown of ERBB3 and／or osimertinib on the proliferation of HCC827 cells were evaluated by 3?(4,5?dimethyl?2?thiazolyl)?2,5?diphenyl?2H tetrazolium bromide ( MTT) assay. Cell apoptosis induced by MALAT1 overexpression, knockdown of ERBB3 and／or osimertinib treatment were analyzed by flow cytometry analysis. The expressions of EGFR and ERBB3 signal pathway related proteins in HCC827 cells treated with overexpression of MALAT1, knockdown of ERBB3 and／or osimertinib treatment were detected by western blot. Results The MTT assay showed that sensitivity to osimertinib of HCC827／MALAT1 cells were significantly repressed. The 50% inhibitive concentration (IC50 ) of osimertinib ＞4 000 nmol／L in HCC827／MALAT1 cells.However, knockdown of ERBB3 facilitated the anti?proliferation effect of osimertinib, and the IC50 of osimertinib in shRNA?ERBB3 cells was (17.27±3.21) nmol／L. The results of flow cytometry analysis showed that the apoptotic rate of HCC827／MALAT1 cells induced by 10 nmol／L osimertinib was (8.38±0.92)%, significantly lower than ( 27.17± 5.83)% of knockdown of ERBB3 ( P＜0.01). Western blotting showed that the expression of p?ERBB3, p?AKT and p?extracellular regulated protein kinases ( ERK) in HCC827／MALAT1 cells was markedly up?regulated, while the expression of p?epithelial growth factor receptor (EGFR) was inhibited. The expressions of p?ERBB3, p?AKT and p?ERK were marginally affected by osimertinb. However, osimertinib downregulated the expressions of p?EGFR, p?ERBB3, p?AKT and p?ERK in ERBB3 deleted cells. Conclusions MALAT1 confers resistance to osimertinb in HCC827 cells by activating of the ERBB3／PI3K／AKT and ERBB3／MAPK／ERK signaling pathways.

Objective To investigate the relationship of procollagen?lysine 2?oxoglutarate 5?dioxygenase 2 ( PLOD2 ) expression and the clinical characteristics of osteosarcoma, and explore the potential mechanism of tumour metastasis promoted by PLOD2. Methods The expression of PLOD2 in osteosarcoma tissues and paired adjacent tissues were detected by immunohistochemistry and qRT?PCR. Correlation of PLOD2 expression in osteosarcoma with the clinical pathologic features was analyzed by Chi square test and Kaplan?Meier analysis.Fibrillar collagen formation and collagen deposition in the tumor tissues were detected by picrosirius red staining. We transfected U?2OS cells with LV?vector, LV?over／PLOD2, sh?NC and sh?PLOD2. The expression of PLOD2 was detected by qRT?PCR. The impact of POLD2 on U?2OS cell invasion was determined by wound?healing assay and Transwell migration assay. The expressions of PLOD2／FAK／JAK2?STAT3 signal pathway related proteins were detected by western blotting. Results The high expression level of PLOD2 in osteosarcoma tissues was 72.5%, significantly higher than 0% in paired adjacent noncancerous tissues ( P＜0.01), the expression of PLOD2 was positively correlated with lymph node metastasis, pulmonary metastasis and poor outcome (P＜0.01). The same results were also observed in qRT?PCR assay. The median survival time of patients with high expression of PLOD2 protein was 13 months, significantly shorter than 32 months of patients with low expression of PLOD2 ( P＜0.05). The result of picrosirius red staining showed that the percentage of collagen fiber deposition in the osteosarcoma tissue with high level of PLOD2 was (74.43+9.63)%, significantly higher than ( 9.67± 1.28)% in tissue with low expression of PLOD2 (P＜0.001).The result of wound?healing and Transwell migration assay showed that over?expression of PLOD2 markedly promoted the invasion, however, knockdown of PLOD2 suppressed the invasion of U?2OS cells ( both P＜0.01).The result of western blotting showed that over?expression of PLOD2 significantly increased the expression levels of p?FAK, p?JAK2, p?STAT3, but knockdown PLOD2 decreased the levels of p?FAK, p?JAK2, p?STAT3 in U?2OS cells. Conclusions Up?regulation of PLOD2 in osteosarcoma is correlated with lymphatic and distant metastasis. PLOD2 promotes invasion and metastasis of osteosarcoma might through FAK／JAK2?STAT3 signal pathway.
