Objective To discuss the relevance between the serum prostate specific antigen (PSA) level and the prostatic cancer biopsy detection rate after tamsulosin treatment for patients with lower urinary tract symptoms and elevated PSA level.Methods 168 patients with lower urinary tract symptoms and elevated PSA level were divided into two groups according to the serum PSA level change after tamsulosin treatment:in the first group,serum PSA level decreased slightly (PSA≥4.0 ng/ml and PSA decrease＜20％);in the second group,serum PSA level decreased obviously (PSA＜4.0 ng/ml or PSA decrease≥20％).Tamsulosin treatment was given in 0.2 mg/d for two months.Prostate gland aspiration biopsy was performed at the end of tamsulosin treatment.Result For the 68 patients of the first group,after tamsulosin treatment,the tPSA level increased from (8.11 ±2.09)ng/ml to (9.05±3.13)ng/ml,in which 38 patients (55.88％,38/68) were confirmed as the prostatic cancer by pathology.For the 100 patients of the second group,after tamsulosin treatment,the tPSA level decreased from(7.80±3.79)ng/ml to (5.19±2.32)ng/ml,in which 6 patients (6％,6/100) was confirmed as the prostatic cancer by pathology.There was significant statistical differences of prostate aspiration biopsy detection rate between the two groups(x2=23.53,P＜0.05).For patients with lower urinary tract symptoms who received tamsulosin treatment,the sensibility of PSA increased to 86.4％,specificity increased to 75.8％,the rate of avoiding aspiration was 55.9％,and the rate of correct diagnosis was 78.5％.Conclusion Tamsulosin treatment can increase the prostatic cancer diagnostic positive rate and decrease the aspiration rate in patients with lower urinary tract symptoms and elevated serum PSA level in a certain extent.

Objective To investigate the condition of inflammation and prethrombotic state (PTS) of the aged patients with coronary heart disease(CHD) complicated with esstential hypertension(EH) and type 2 diabetes mellitns(T2DM). Methods The levds of fasting plasma hs-CRP,D-D and VWF were all measured in 86 CHD patients with EH,84 patients with T2DM,80 patients with EH and T2DM,91 CHD patients and 79 normal cases. Results Compared with normal group,diseases groups had significantly higher hs-CRP,D-D,and VWF,but compared with CHD with EH and T2DM group,other diseases groups had lower hs-CRP,D-D and VWF(P <0.05) ;The concentration of serum hs-CRP was positively correlated with D-D and VWF in CHD group (P < 0. 05). Conclusion The inflammation and hypercoagulable state is more significant in CHD patients with EH and T2DM,thns the levels of plasma hs-CRP,D-D and VWF play an important role in the treatment.

Objective To evaluate the feasibility and safety of the treatment for ventricular septal rupture (VSR) by transcatheter interventional therapy coordinated with percutaneous coronary intervention (PCI) or percutaneous transluminal coronary angioplasty (PTCA).Methods Six patients who suffered from cardiogenic shock due to acute myocardial infarction (AMI) and VSR were given intra-aortic balloon pump (IABP) and mechanical ventilation support. After three weeks, they underwent transcatheter closure of ventricular septal rupture with Amplatzer ventricular septal occluder, and at the same time PCI and PTCA were performed. Results All the patients successfully underwent ventricular septal defect occlusion, including two cases of residual shunt. Segmental stenosis of the middle of anterior descending branch and circumflex artery were noted in three patients, and then stent implantation was used. The other three cases had multi-vessel lesion but were without stent implantation. All the patients with stent implantation survived and discharged. Conclusions It is safe and feasible to apply transcatheter closure of ventricular septal rupture with Amplatzer ventricular septal occluder, coordinated with PCI and PTCA for patients with acute myocardial infarction complicated with ventricular septal rupture.

Objective To understand the feeling of family caregiver of children with chronic connective tissue disease (CTD).Methods A semi-structured interview was conducted with 30 family caregivers of children with CTD.Data were analyzed based on Colaizzi's phenomenological research method.Results The family caregiver's feelings were classified into four themes,including heavy psychological burden,diseases affecting family life,uncertainty in illness,demands for social support.Conclusions We should neglect the burden and related problems of caregivers when paying attentions to health problems of children,and supply effective intervention measures in order to increase the health level of children and their caregivers.

Objective To investigate the effects of montelukast(MK),a selective cysteinyl leukotriene receptor 1 antagonist on interleukin(IL)-5 and eotaxin expression as well as serum total immunoglobulin E(IgE) production during MK treatment of mouse acute asthma airway inflammation.Methods Sensitized Balb/c mice were challenged by ovabumin(OVA)to establish the acute asthmatic mo-(del).Twenty-five mg/kg of MK(MK group) or Saline(Saline group)were given by intravenously for 3 days.Cellular infiltration of bronchoalveolar larvage fluid(BALF) were assessed by Wright staining.Production of IL-5 and eotaxin in the lung or BALF and serum IgE were determined by enzyme linked immunosorbent assay(ELISA).The expression of IL-5 and eotaxin mRNA were measured by semi-quantified reverse transcriptase-polymerase chain reaction(RT-PCR).Plasma MK level was determined by liquid chromatography.Results After 24 h OVA challenge,the numbers of total white blood cells,neutrophils and eosinophils(EOS)of BALF were(26.0?18.9)?10~7/L,(5.92?8.09)?10~7/L and(0.74?0.88)?10~7/L in MK treatment group.They were significantly reduced compared with those in Saline group,respectively(P80%.The level of IL-5 in BALF and lung tissue were(48.52?14.45) ng/L and(27.40?9.62) ng/g protein in MK group,which significantly declined compared with that in saline group;BALF eotaxin level declined too.Serum IL-5 and total IgE level were also significantly reduced;IL-5 mRNA expression in lung significantly decreased.Eotaxin and its mRNA expression in lung were not decreased significantly.Conclusion MK(exerts) its anti-inflammatory effect mainly through the suppression of IL-5 and IgE production.

Objective To evaluate the therapeutic effects of stereotactic conformal radiotherapy (SCRT) on 30 cases of thalamic and brainstem tumors. Methods During the period from October 1997 to April 2002, 30 patients, 19 male and 11 female, with an age range from 13 to 68 years (an average of 37 years) suffering from thalamic and brainstem tumors, were treated in our institute. The size of the tumors ranged from 3.5 cm 3 to 73.0 cm 3 with an average of 16.5 cm 3. Eight cases were treated with SCRT after regular radiotherapy, 7 cases were treated with SCRT after surgical resection of the tumor and 15 cases were treated with SCRT only. Results The clinical symptoms of all the patients disappeared thoroughly. Their KPS was significantly improved (P

14mm.Results Group thick cycles had significantly lower implantation and pregnancy rates compared with group normal cycles(9.1% versus 13.5% and 18.8% versus 27.0%,respectively).Group thick cycles had significantly higher miscarriage rates compared with group normal cycles(50.0% versus 19.0%,respectively).Conclusion Increased endometrial thickness is associated with the decreased implantation or pregnancy rates and the increased miscarriage rates in IVF-ET.
