Objective To investigate the effect of mitogen-activated protein kinase(MAPK)pathway on the transcriptional expression of mdr1 gene induced by doxorubicin ( DOX)and study the transcription regulation of mdr1 gene.Methods K562 cells were treated with DOX(0.01 μg/ml)with the initial concentration of 0.01 μg/ml for 24 hours,then change the culture media without DOX.K562 cells were cultured until the its status wag recovered.Subsequently the cells were treated with DOX(0.02μg/ml)for 24 hours again.The concentration of DOX was increaged until 0.05 μg/ml by following the protocol above.K562 cells were collected at the concentration of 0.01 μg/ml,0.03μg/ml and 0.05μS/ml DOX.Expression of mdr1 gene were examined by reverse transcription-polymerase chain reaction(RT-PCR).Pglycoprotein(P-gP)wag detected by flow cytometry.Western blot wag performed to detect ERK and P-ERk.K562 cells were pretreated with MAPK inhibitor PD98059 for 1 hour.and then DOX was added.RT-PCR and FCM were used to detect the expression of mdr1 mRNA and P-gp.Results When K562 cells were exposured to DOX.the phosphorylation of ERK wag increaged.the mdr1 gene wag highly expressed as well as its corresponding protein P-gp.When the concentration of DOX was 0.05μg/ml,the expression of mdr1 gene and P-gp were increased over 5 fold.When K562 cells were pretreated with MAPK inhibitor PD98059,the expression of mdr1 gene induced by DOX(the concentration was 0.03 μg/ml and 0.05 μg/m1)was effectively inhibited by(74.1±0.11)%and(70.2±0.14)%respectively.Conclusions DOX could induce the expression of mdr1 gene in K562 cells accompanied by the activation of MAPK/ERK pathway.The block of activation of ERK could inhibit the induced expression of mdr1 gene.

Objective To study the expression of the long non-coding RNA-BC043614 in pancreatic ductal adenocarcinoma (PDAC) and to analyse the relationship between the clinical pathological data and the prognosis of PDAC.Methods The clinical data of 42 patients who had PDAC treated from June 2013 to June 2014 were retrospectively analyzed.Real-time fluorescence quantitative PCR (qRT-PCR) was performed to detect the difference in expression of lncRNA-BC043614 between PDAC and its adjacent normal tissues.Correlation between the expression of lncRNA-BC043614 in PDAC and the clinical pathological characteristics was analyzed by the x2 test.The potential of lncRNA-BC043614 in predicting prognosis in patient with PDAC after operation was assessed using the Log-rank test and the Cox's proportional hazards regression model.Results The expression of lncRNA-BC043614 was markedly higher in PDAC than in its adjacent normal tissues (P ＜0.05).The expression of lncRNA-BC043614 in PDAC was significantly correlated with tumor size,tumor differentiation,vascular carcinoma,and CA19-9 serum levels (P ＜ 0.05).Patients with a higher expression of lncRNA-BC043614 in PDAC had a significantly shorter tumor-free survival (P ＜0.05).A high expression of lncRNA-BC043614 in PDAC was an independent risk factor of tumor-free survival in patients with PDAC after operation (P ＜ 0.05).Conclusions lncRNA-BC043614 was highly expressed in pancreatic cancer tissue and it correlated with the patient's tumor-free survival.lncRNA-BC043614 can be used as a new prognostic biomarker.

OBJECTIVETo investigate the quantity, quality and effect of health management service project for patients with hypertension and diabetes in basic public health service project of Sichuan province.

METHODS44 health clinics or community health service center, 22 counties and 11 cities was extracted by method of multistage stratified sampling on March, 2014. In each institution we sampled 10 resident health record of hyperpietic and 10 of diabetic. Number of managed patients was recorded to calculate the rate of health management. Telephone survey was used to judge the accuracy and standardability of services the patients received according to the national basic public health service specifications. We compared the satisfaction rate and blood pressure/blood sugar control rate of patients which had accurate record to which had not, and which got normative services to which didn't.

RESULTS33.8% (69 680/206 154) of the hyperpietics and 24.0% (25 562/106 508) of the diabetics were managed. 81.16% (702/865) of the records were with accurate information. 74.36% (522/702) of the patients received normative services. Blood pressure was well controlled in 86.92% (299/344) of the hyperpietics, and FPG was well controlled in 85.46% (288/337) of the diabetics. The satisfaction rate was 94.58% (698/738). The satisfaction rate of patients which had accurate record was 98.69% (677/686), but of which had not was just 40.38% (21/52) (χ² = 320.52, P < 0.001). The satisfaction rate of patients which got normative services was 99.22% (508/512), and of which did not get was 97.13% (169/174) (χ² = 2.92, P = 0.087).

CONCLUSIONThe quality of managed chronic patients was well, and got obvious effect. Measures need to implement for increasing the management rate, accuracy and standardability of health management services for hyperpietic and diabetic.

OBJECTIVETo evaluate the effect of basal serum luteinizing hormone (LH) and luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio on the clinical outcomes of in vitro fertilization-embryo transfer (IVF-ET) in patients with polycystic ovary syndrome (PCOS).

METHODSA retrospective analysis was performed of 134 IVF cycles in patients with PCOS. The cycles were classified into 2 groups according to serum levels of LH and also into 2 groups according to LH/FSH ratio, namely group A1 (LH≤10 IU/L), group A2 (LH>10 IU/L), group B1 (LH/FSH ratio<2), and group B2 (LH/FSH ratio≥2). The clinical characteristics, embryological data and pregnancy outcomes were compared between the groups.

RESULTSPatients in group A2 showed significantly higher FSH, T level, and LH/FSH ratio with a greater number of oocytes retrieved than those in group A1, but the time for down-regulation, duration of stimulation, AFC, LH and LH/FSH on the first day of stimulation, embryological data and pregnancy outcomes did not differ significantly between the two groups. Compared with group B1, group B2 showed higher basal LH, E2 level on the day of HCG, more oocytes retrieved and lower dose of gonadotropins used, but the time for down-regulation, duration of stimulation, LH and LH/FSH on the first day of stimulation and pregnancy outcomes were comparable between the two groups.

CONCLUSIONA high basal LH level or a high LH/FSH ratio does not produce obvious deleterious effect on the clinical outcomes of IVF-ET in women with PCOS who take oral contraceptives for pretreatment before long GnRH-agonist protocol.
