Objective:To observe the effect and evaluate the necessity of reducing nurse-students' psychological pressure before practice.Methods:To making measures to help 318 nurse-students of grade 2004 reduce psychological pressure two months before practice,investigate and contrast the psychological situations of nurse-students before and after reducing psychological pressure.Result:58.8 percent of nurse-students are under psychological pressure in varying degrees before practice.The students from one-child families are under higher pressure than those from non-one-child families.The percentage was reduced from 58.8 percent to 18.2 percent after taking the measures.The difference is notable(P

PurposeTo compare measures of coronary flow reserve by an intracoronary Doppler guide wire with results of dipyridamole emission computed tomographic 201T1/ 99m Tc-sestamibi myocardial imaging(SPECT).MethodsThe coronary blood flow velocity were measured by Cardiometrics Flomap Ⅱ and 0. 014 or 0. 018 inches Doppler flowire in 27 patients (55 arteries) with coronary angiography. 8 patients (19 arteries )without underlying diseases of coronary microvascular lesions were studied as the normal control. The proximal and distal average peak velocity (APV), diastolic/systolic velocity ratio (DSVR), CFR and proximal/distal velocity ratio (P/DVR) were measured. The results were compared with that of SPECT before angiography. ResultsAccording to the CFR measured by Doppler fiowire, the arteries were divided into two groups:Group A, consisted of 33 arteries with CFR > 2.0. Group B consistedof 22 arteries with CFR≤2.0. CFR of group A was significantly higher than that of group B (P< 10 - 7). Among 22 arteries with abnormal CFR, SPECT could detect 16. Among 33 arteries with normal CFR, all arteries except 2 showed normal SPECT. With intracoronary Doppler flowire as reference, the sensitivity and specificity of dipyridamole SPECT were 72.73 % and 93.94 %. With results of dipyridamole SPECT as reference, the sensitivity and specificity of intracoronary Doppler CFR were 88.89% and 83.78%. Their conformability rate was 85.45%.Conclusions In evaluating coronary reserve function, results of dipyridamole SPECT was rather conformable to measures of intracoronary Doppler CFR, but they cannot be replaced each other.

Objective To investigate the multiple risk factors for lower extremity lymphedema in patients following treatment of common gynecologic cancers by meta-analysis for systematic analysis and comprehensive quantitative study.Methods Clinical trials published up until August 2016 were retrieved from PubMed, Embase, and the Cochrane Library.The quality of the included studies was assessed by the Newcastle-Ottawa Scale, and data analysis was performed using Stata 14.0 and RevMan 5.3.The strength of the associations between risk factors and gynecologic cancer-related lower extremity lymphedema was described as odds ratio (OR) and 95% confidence intervals (CI).Results Eighteen studies were included in the meta-analysis, and 8 relevant factors were identified.The risk factors for lower extremity lymphedema after treatment of gynecologic cancer mainly included radiotherapy (OR=2.45, 95%CI:2.05-2.95, P=0.000), FIGO stage (OR=2.29, 95%CI:1.66-3.14, P=0.000), and pelvic lymph node dissection (OR=2.00, 95%CI:1.02-3.91, P=0.040).Conclusions Radiotherapy, FIGO stage, and pelvic lymph node dissection are the main risk factors for lower extremity lymphedema after treatment of gynecologic cancers.

Objective To investigate the expression and significance of B lymphocyte stimulator (Blys) and its receptor BAFF (BAFF-R) in peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE). Methods The expression of Blys and BAFF-R was measured by flow cytometry in 90 pa-tients with SLE,which was compared with that of 45 healthy controls. The relationships between the expression of Blys, BAFF-R and other laboratory parameters as well as disease activity were analyzed. Results The expression of Blys and BAFF-R in PBMCs from patients with SLE was significantly elevated compared to healthy controls (P <0.001), so did the active group (P < 0.001) and inactive group (P < 0.001 and P < 0.01). The expression of Blys in PBMCs from active SLE patients was higher than that of inactive patients (P <0.05). However,there was no statisti-cal difference of BAFF-R between the two groups. The expression of Blys in PBMCs was positively related to SLEDAI (r =0.728,P <0.001) ,IgG and IgM(r=0.691,P<0.001 and r =0.453,P<0.01) ,but negatively related to C3 and CA (r = -0.510, P < 0.001 and r = -0.312, P < 0.05). The expression of Blys in dsDNA positive group was higher than those of dsDNA negative group (P < 0.01). The expression of Blys and BAFF-R in Cl qAb positive group was higher than those of ClqAb negative group as well (P <0.01). Conclusion The expression of Blys and its receptor BAFF-R in PBMCs from SLE is elevated ,which may reflect the disease activity and is related to the pro-duction of autoantibody. They might be involved in the pathogenesis of SLE.

Objective To investigate the effect of histone deacetylase inhibitor LBH589 on proliferation,apoptosis and drug resistance of chemoresistant acute myeloid leukemia cells HL60/ADM.Methods HL60/ADM cells were treated with LBH589.Proliferation,apoptosis and adriamycin IC50 were evaluated by MTT assay and AnnexinV-FITC/PI stain.The change in MRP1 expression and intercellular adriamycin accumulatiom were analyzed by flow cytometry.Results Effective proliferative inhibition and apoptotic induction in HL60/ADM cells were observed after treatment with 10-80 nmol/L LBH589 with maximal effect detected after treatment with 70 nmol/L LBH589 for 60 hours.However,inhibition ratio remain unchanged with the further increase of drug dose and incubation time (P ＞ 0.05).Downregulation of MRP1 [(93.90±4.20) ％ vs (76.19±6.53) ％],upregulation of adriamycin accumulation [(8.53±0.68) ％ vs (25.67±1.34) ％] and decrease in adriamycin IC50 [(6.833±0.319) μg/ml vs (1.382±0.104) μg/ml] were induced by the treatment with 20 nmol/L LBH589 (P ＜ 0.01),whose reversal fold was 4.9.The expression of acetylated histone 3 after treatment with LBH589 was higher than that before treatment (P ＜ 0.01).However,relative p-Akt levels after treatment for 24 h and 48 h were 1.07±0.09 and 0.59±0.01,respectively,which were lower than that before treatment (2.03±0.12) (P ＜ 0.01).Meanwhile,expression levels of p53 were 0.57±0.04 and 1.31±0.09,respectively,which were higher than that before treatment (0.21 ±0.02) (P ＜ 0.01).Conclusion Treatment with LBH589 has the capability of inhibiting proliferation and inducing apoptosis,as well as increasing intercellular adriamycin accumulation and sensitivity through downregulation of MRP1 expression and inhibition of PI3K-Akt signaling pathway in HL60/ADM cells.

Objective To investigate the risk factors of disease progression and adverse pregnancy outcome in patients with systemic lupus erythematosus (SLE) during pregnancy.Methods Clinical data of 118 pregnant women with SLE admitted from June 2004 to October 2015 were retrospectively analyzed.The patients were divided into selective pregnant group (group A,n =72 cases) and non-selective pregnant group (group B,n =46) according to the disease activity of SLE.The disease progression and pregnancy outcomes were compared between two groups.Results The various system damages occurred in group B,including hematological damage in 16 cases,kidney damage in 19 cases,erythra in 10 cases,arthritis in 10 and serositis in 12 cases;while the corresponding cases in group A were 10,14,6,4 and 4(x2 =7.133,P=0.008;x2 =6.658,P =0.010;x2 =4.304,P =0.038;x2 =7.030,P =0.008;x2 =10.095,P =0.001).SLE exacerbation occurred in 28 cases (74％) of group B and 12 cases (17％) of group A (x2 =34.944,P =0.000).The logistic regression analysis showed that hypocomplementemia,proteinuria,SLEDAI score before pregnancy and positive anti-dsDNA antibody were the risk factors of SLE disease exacerbation during pregnancy.The maternal complications occurred in group B,including pregnancyinduced hypertension in 7 cases,preeclampsia in 10 cases and infections in 11 cases/times;while the corresponding cases (case/time) in group A were 2,6 and 4 (x2 =4.526,P =0.033;x2 =4.304,P =0.038;x2 =8.525,P =0.004).There were 14 cases of therapeutic induced labor,7 case of stillbirth and 27 cases of total fetal loss in group B,while the corresponding cases in group A were 2,0 and 4 (x2=18.317,P =0.000;x2 =9.080,P =0.003;x2 =40.920,P =0.0300).The logistic regression analysis showed that positive anticardiolipin antibody,proteinuria,SLEDAI score before pregnancy and renal dysfunction during pregnancy were risk factors of fetal loss.There were 87 cases of successful delivery (73.7％),the successful delivery rates were 41.3％ (19/46) in group B and 94.4％ (68/72) from group A,respectively.The infant complications occurred in group B,including premature birth in 15 cases,low birth weight in 13 cases,neonatal jaundice in 5 cases and mild asphyxia in 5 cases;while the corresponding cases in group A were 24,18,4 and 2 (x2 =11.442,P =0.001;x2 =11.395,P =0.001;x2 =4.664,P =0.031;x2 =8.035,P =0.005).Conclusion SLE patients whose disease conditions are not well controlled would lead to higher percentage of disease deterioration during pregnancy and worse pregnancy outcomes.

The clinical manifestation,endoscopic findings and histopathological characteristics of 162 patients with gastrointestinal schistosomiasis were retrospectively analyzed.Among 162 patients,there were 29 cases of gastric schistosomiasis and 133 cases of intestinal schistosomiasis.The main clinical manifestations included stomachache,diarrhea and mucous bloody stool.Endoscopic findings:in 29 cases of gastric schistosoniasis,18 were ulcerative type,5 inflammatory type,6 proliferative type and 7 cases combined with gastric cancer.In 133 cases of intestinal schistosomiasis,17 were acute inflammatory type,81 chronic inflammatory type,33 mixture inflammatory type and 32 combined with colorectal cancer.Forty nine cases (30.25％) were misdiagnosed for various reasons; commonly misdiagnosed as ulcerative colitis,intestinal tuberculosis,chronic gastritis,and gastrointestinal tumors.There are no specific clinical manifestations or endoscopic findings of gastrointestinal schistosomiasis; epidemiological data,endoscopy combined with multi-site multi-block biopsy may improve the diagnosis.
