Objective: To understand the impact of the career planning counseling on college students' life education and to explore an effective way of it;Ways: To influence the experimental classes through lectures,conversation guide,broadcast courseware and guiding team during a period of seven months and to measure the experimental results through questionnaire survey and field interviews.Results: after the experimental class students are superior to the control class students in academic performance,activities participation,mental outlook,attitude to life and psychological health significantly.Conclusion: Career planning counseling has a positive impact on life education.

Objective To assess the expression of thioredoxin reductase(TR)and thioredoxin (Trx)mRNA,TR activity in human placenta in women with preeclampsia,and to discuss the relationship between Trx system and the pathogenesis of preeclampsia.Methods Twenty-sixwomen with preeclampsia(10 mild and 16 severe)and 28 healthy gravidas (control) were included in this study.Semi-quantitative reverse transcription polymerase chain reaction(RT-PCR)were employed to demonstrate the expression of TR and Trx in placentas.TR activity was measured spectrophotometrically.Results The expression of TR mRNA(mild:0.865±0.018;severe:0.800±0.025,P＜0.05)and Trx mRNA(mild:0.873±0.008;severe:0.818±0.025,P＜0.05)were lower in placenta of preeclampsia than in the control group(TR mRNA:0.893±0.023;Trx mRNA:0.918±0.023.P＜0.05),and those levels in the severe preeclampsia group were lower than in the mild ones.Both the mild and severe preeclampsia groups showed lower TR activity than the control(mild:17.732±1.653;severe:15.626±1.543 vs 19.770±2.432,P＜0.05),and that of the severe preeclampsia group was lower than that of the mild ones.Positive correlation was found between the TR activity and TR mRNA expression in both groups(r=0.612,P＜0.001).Conclusions Abnormal decreased expression of TR mRNA and Trx mRNA and TR activity in human placenta of preeclampsia might participate and play an important role in the pathogenesis of preeclampsia.

Objective To investigate the level of serum vascular endothelial growth factor and soluble vascular endothelial growth factor receptor-1 in patients with pre-eclampsia and eclampsia.Methods Serum vascular endothelial growth factor and soluble vascular endothelial growth factor receptor-1 in peripheral venous blood were determined by ELISA in patients with pre-eclampsia(n=9),severe pre-eclampsia(n=10) and eclampsia(n=5)(total eclampsia n=24) and healthy controls(n=18).Results Patients with pre-eclampsia and eclampsia had higher level of serum sVEGFR-1(pre-eclampsia:58?7 mg/L,severe pre-eclampsia:82?15 mg/L,eclampsia:96?13 mg/L vs control:11?3 mg/L,P

Objective To evaluate the expression and discussion on high mobility group protein ( HMGB1 )/toll like receptor 4 ( TLR4 ) and NF-κB possible role in the signaling pathway in preeclampsia .Methods Ten patients with mild preeclampsia(MP), 20 patients with severe preeclampsia (SP) and 30 cases of normal pregnancy were recruited the same period.To check the expression of the HMGB1,TLR4,NF-κB P65 protein in placenta tissue using Immunohistochemical staining .Levels of HMGB1, TLR4, NF-κB P65 in blood serum were measured by ELISA.Results 1)ExpressionofHMGB1,TLR4,NF-κBP65wereincreasedascomparetocontrolgroup(P<0.05);HMGB1,TLR4,NF-κB P65 in placenta of patients with severe preeclampsia and mild preeclampsia failed to show significant difference .2) HMGB1,TLR4,NF-κB P65 in women with preeclampsia was significantly higher than control group ( P<0.05 ); HMGB1,TLR4,NF-κB P65 in women with severe preeclampsia showed a higher level as compared to mild preeclampsia (P<0.05).Conclusions HMGB1,TLR4 and NF-κB P65 were over-ex-pressed in the placenta tissue and serum in patients with preeclampsia , which indicated that HMGB1,TLR4 and NF-κB P65 may play an important role in the development of preeclampsia .

Objective To assess the feasibility,safety and efficacy of endoscopic papillectomy (EP) for tumors at the ampulla of Vater (AV).Methods A total of 15 patients with tumor at AV that were indicated for EP were included in this prospective study.Their clinical profiles,procedural parameters and outcome were evaluated.Results All patients underwent EP procedure successfully.Four patients who were diagnosed as having chronic inflammation in the reference endoscopy were confirmed as having adenoma after EP.Out of the 11 patients who were previously diagnosed as andenoma on biopsy,2 of low differentiated adenocarcinoma,1 of well differentiated adenocarcinoma and 1 malignant transformation were pathologically confirmed after EP.Stents were implanted in 8 patients with dilated pancreatic and/or common bile duct.Except for 2 cases of melena and 2 transient elevated level of blood amylase after EP,no other major complications occurred.Three patients,including 1 case of low-differentiated adenocarcinoma,1 case of malignant transformation and 1 case of lesion residual,were referred to surgery,another patient with low-differentiated adenocarcinoma declined any additional intervention because of old age.In the remaining 11 cases ( 11/15,73.3％ ) including one well differentiated adenocarcinoma,no recurrence was observed during a follow-up period of 23.4 (5 to 47) months.Conclusion EP is a minimal invasive,safe and effective treatment for tumors at AV,which also can provide an accurate staging of the lesion.
