Objective To evaluate the quality of life (QoL) in patients undergone intravesical chemotherapy for non-muscle invasive bladder cancer and analyze the correlation of the quality of life and low urinary tract symptoms in this group of patients.Methods 31 male patients and 15 female patients were enrolled from Jan.2012 to Mar.2013.The average age was 54 (35-71) years.Questionnaires of QoL and core lower urinary tract symptom score (CLSS) were given to 46 patients before intravesical chemotherapy and the 1 st,6th month after starting the instillation.Before the instillation,the scores of QoL and CLSS were 55.7±6.2 and 6.5±2.1,respectively,the change of QoL and CLSS were compared to baseline,and then the correlation of the low urinary tract symptoms and quality of life was analyzed.Results At the end of 1st and 6th month,the QoL scores were 74.7±8.1 and 78.5± 10.6.The CLSS scores were 8.9±2.0 and 9.1 ± 1.8,respectively.The differences were significant (P ＜0.05) when compared to the baselines.The areas of working activity and free time were affected much more than other areas,and the scores increased from 8.3±2.1 and 19.2±5.7 to 14.3±5.6 and 23.7±4.2,respectively.The area of free time was found to be associated with local symptoms (r=0.61).Conclusions Intravesical treatment can impair the QoL of patients.Low urinary tract symptom is an important factor and is associated with impairment of QoL,suggesting the relief of local symptoms may improve the overall quality of life.

Objective To investigate the effects of three procedures for benign prostatic hyperplasia (BPH) on neuroendocrine and immune responses and its clinical significance. Methods Patients were divided into three groups with 20 patients in each group: the Group Ⅰreceived the transuretheral resection of prostate (TURP), the Group Ⅱ received the suprapubic transvesical prostatectomy (SPP) and the Group Ⅲ underwent the retropubic prevesical prostatectomy (RPP). The pre- and post- operative serum concentrations of Interleukin-6 (IL-6) and cortisol as well as changes of T-cell subgroups in the three groups were analyzed , respectively. Results Serum IL-6 concentrations remarkably increased at the third postoperative hour in patients of all the three groups, but those in Group Ⅱ and Group Ⅲ were significantly higher than those in Group Ⅰ( P 0 05). The ratio of CD 4 +/CD 8 + decreased markedly on the second postoperative day in Group Ⅱ and Group Ⅲ ( P

Objective To explore the effect of operative treatment of hypertensive intracerebral hemorrhage.Methods 386 cases with hypertensive intracerebral hemorrhage were retrospectively analysed,hematoma was removed through big bone flap and small skull window,or drainage and urokinase infusion with small hole puncture.Results 39 cases died(10.1%),according to ADI grade system:Ⅰ 106 cases(27.4%),Ⅱ 136 cases(35.2%),Ⅲ 50 cases(13%),Ⅳ 43 cases(11.1%),Ⅴ 12 cases(3.2%).Conclusion To increase the cure rate and life quality,and obtain a lower mortality,it is a key to do surgical operation such as microsurgery or drainage and urokinase infusion.

Objective To investigate clinical value of miRNA-27-3p expressed in colorectal cancers,liver metastasis,and the peripheral blood,and analyze its target genes.Methods Among 78 cases of colorectal cancer patients,sera,colorectal cancers,and liver metastases were used to detect miRNA-27a-3p expressions with real-time quantitative polymerase chain reaction (RT-PCR) and analyze its clinical significance.We predicted miRNA-27-3p target genes,and confirmed the target genes and their correlation between miRNA-27a-3p and target genes.Results The expression level of miRNA-27a-3p in 78 cases of colorectal cancers was 3.13 ± 1.72,which was significantly higher than that in matched adjacent cancer tissues (1.06 ± 0.42) and control group (0.68 ± 0.27) (P ＜ 0.05).The expression level of miRNA-27a-3p in 27 cases of liver metastases was 3.48 ± 1.15,which was significantly higher than that in paired colorectal cancer tissues (2.34 ± 1.03) (P ＜0.05) and adjacent tissues (0.81 ± 1.14) (P ＜0.05).Expression levels of miRNA-27a-3p in patients with colorectal cancer tissues and peripheral blood had no significant difference in age,sex,serum carcinoembryonic antigen (CEA) levels,tumor location,and pathological types (P ＞ 0.05);however,it had positive significant difference in lymph node metastasis,liver metastasis,tumor node metastasis (TNM) staging (P ＜ 0.05).The expression of miRNA-27a-3p was negatively correlated with the expression of target gene GP73.Conclusions The higher expression was miRNA-27a-3p in peripheral blood and colorectal cancer tissues,higher risk of liver metastasis occurs.MiRNA-27a-3p might participate in the occurrence and development of colorectal cancer by regulating target gene expression of GP73.In peripheral blood of colorectal cancer patients,miRNA-27a-3p might be used for potential auxiliary diagnosis and predict liver metastasis.

Objective To analyze the CT findings of heterotopic pancreas and the correlation with pathologic changes.Methods CT findings in 1 9 patients with heterotopic pancreas proven by surgery were reviewed retrospectively,14 of whom were scanned with enhanced CT.The correlation of CT findings and pathologic results were also analyzed.Results All patients had a single lesion with sized range from 0.8 to 4.7 cm and mean diameter of (2.2±0.6)cm.All lesions with homogeneous density were showed on plain scans including 7 lesions in stomach,8 in duodenum,2 in jejunum,1 in ileum and 1 beside the cardiac lymph nodes.The border of the lesions in 5 was unclear with exudative changes,mimicking acute pancreatitis.A sign of central umbilical concave was found in 2.Pathological results confirmed 14 lesions in submucosa,3 in muscular layer,1 in serosal layer and 1 in abdominal cavity.Hetero-topic pancreas presented early obvious enhancement in 9,mimicking normal pancreas,which was composed chiefly of pancreatic aci-ni.The enhanced degree of 4 lesions was lower than normal pancreas,which were composed of pancreas ductal epithelium and few pancreatic acini.No significantly enhancement was seen in 1,mimicing liomyoma,which was composed chiefly of pancreas ductal epithelium and smooth muscle hyperplasia.Conclusion Heterotopic pancreas in most cases presents characteristic submucosal disea-ses-like pattern,and different enhanced patterns of heterotopic pancreas are related with the pathologic changes.

Objective To investigate the association of vascular calcification,fetuin A and Creaction protein (CRP),and explore the influence on cardiovascular events.Methods Sixty peritoneal dialysis (PD) patients were enrolled in this study.Carotid intima-media thickness (cIMT),fetuin A and CRP,along with the other serum related parameters were detected to find out their influence on vascular calcification in PD patients.The relationship between cIMT,fetuin A,CPR and cardiovascular events was analyzed in PD patients with 18 months followed-up.Results Of the 60 PD patients,carotid intima-media thickness (cIMT) was increased in 38 patients(63.3％).Compared with the non-increased cIMT patients,serum fetuin A concentration was significantly decreased(P ＜ 0.05),CRP(P＜0.01) and calcium × phosphate products(P＜0.05) were significantly increased in the highincreased cIMT group.Compared with the low-increased cIMT patients,fetuin A concentration was obviously lower(P ＜ 0.05) and calcium×phosphate products were obviously higher(P ＜ 0.05) in the highincreased cIMT group.Linear regression analysis discovered an obvious negative correlation between CRP and fetuin A(R2 =0.629,F=47.522,P ＜ 0.01),as well as fetuin A and calcium×phosphate products (R2=0.299,F=11.948,P=0.002).Multiple regression analysis indicated that fetuin A was independently negatively correlated with cIMT(B=-0.019,t =-6.042,P ＜ 0.01).At 18 months,there were 36 newly-happened cardiovascular events and among which 6 cases died.Logistic regression analysis found that increased cIMT was risk factor to cardiovascular events in PD patients(OR=3.691,95％CI 1.467-9.258,P=0.006).Conclusion Decreased fetuin A and increased calcium×phosphate products deteriorate carotid calcification in PD patients.Micro-inflammation of PD patients represented by high CRP levels may increase calcium×phosphate products by depressing the fetuin A level,and in the end will stimulate carotid calcification.Increased cIMT is a risk factor for cardiovascular events.

Objective To study the relationship between the CT features and pathological grade of malignancy of the gastric stro-mal tumors (GST).Methods A retrospective review was performed based on the database of 80 consecutive patients with GST.Age and gender of the patients were recorded,and the CT findings of GST including growth pattern,morphology,tumor site,boundary, mucosa,serosa,ulcer,volume and maximum diameter of the tumor were also measured.The patients were divided into three groups:very low and low risk group,intermediate risk one and high risk one according to the pathology.All parameters were ana-lyzed by one-way ANOVA or Fisher’s exact test.Results The patients in 3 groups (from low risk to high one)were 30,30 and 20 respectively.There were no significant differences in age,gender,location and mucosa among 3 groups(P>0.05).However,the growth pattern,morphology,boundary,serosa,ulcer,volume and maximum diameter of the tumor were significantly different (P<0.05).Conclusion The CT features including growth pattern,morphology,boundary,serosa,ulcer,volume and maximum diameter of the tumor can be used to evaluate the grades of malignancy in GST.

Objective To explore the value of dual-source CT monoenergetic-plus imaging in the diagnosis of early gastric cancer. Methods Imaging data of 2 6 cases with pathologically proven early gastric cancer who underwent dual-energy scanning were analyzed retrospectively.Monoenergetic-plus images with energy levels at 40 keV,50 keV,60 keV and 70 keV were reconstructed by using an advanced monoenergetic software (syngo.via.VA30A,Dual energy Mono+).Contrast-to-noise ratio (CNR)of the lesion,image noise,overall image quality score and lesion conspicuity score were com pared between different monoenergetic-plus images and conventional polychromatic images at 1 2 0 kVp.Results The CNRs (3 .2 4 ± 0 .7 6 ,2 .9 4 ± 0 .9 2 ,2 .4 7 ± 0 .7 9 ,2 .3 7 ± 0.98 and 1.22±0.40 respectively)and image noises [(32.7±1.82)HU,(25.6±2.61)HU,(20.30±2.1 7)HU,(1 7.03±2.1 5)HU and (18.15±2.12)HU respectively]among 40 keV,50 keV,60 keV,70 keV and 120 kVp groups all had statistical differences (F =24.654 and 227.05,P <0.01).The CNR in 50 keV group was higher than that in 60 keV,70 keV and 120 kVp groups,but similar to that in 40 keV group (P >0.05).The SD value in 50 keV group was lower than that in 40 keV group,but higher than that in other three groups (P <0.05).The overall image quality score (3.08±0.27,3.65±0.49,3.31±0.47,3.23±0.43 and 3.1 5±0.37,respectively) and lesion conspicuity score (4.15±0.67,3.92±0.48,3.27 ±0.45,3.08±0.27 and 3.04±0.20)among the five groups all had statistical differences (Z =25.343 and 70.426,P <0.05).The overall image quality score of 50 keV group was higher than that of the other four groups (P <0.05).Lesion conspicuity score in 50 keV group was higher than that in 60 keV,70 keV and 120 kVp groups and similar to that in 40 keV group (P =0.1 52).Conclusion The 50 keV monoenergetic-plus images can increase the CNR value of early gastric cancer while maintaining the overall image quality.

Objective To investigate the relationship between fetuin A and left ventricular function and their influences on residual renal function(RRF) in peritoneal dialysis patients.Method Eighty patients recently initiating peritoneal dialysis were enrolled into this study and were divided into high fetuin A group and low fetuin A group accordin to the value of serum fetuin A concentration.Hemoglobin,high sensitive C reactive protein(hsCRP),calcium,phosphorus,albumin,lipoproteins and left ventricular myocardial performance index(LV-MPI) were examined.All these patients were followed up for 12 months,to discover the parameters' differences between two groups and to investigate the association between fetuin A and left ventricular function and RRF.Results At the beginning of the study,there was no difference of hsCRP,calcium,phosphorus,albumin,lipoproteins and LV-MPI,estimated glomerular filtration rate (eGFR) between two groups;After 12 months follow-up,MPI was obviously shorter (P ＜ 0.05) and RRF was obviously higher (P ＜ 0.05) in high fetuin A group than thosein low fetuin A group.Compared with the beginning of the study,LV-MPI was significantly increased and eGFR was significantly decreased after 12 months follow-up (both P ＜ 0.05) in low fetuin A group,but no obviously change of LV-MPI or eGFR was found in high fetuin A group after followup.Pearson correlation analysis discovered an obvious negative correlation between fetuin A and MPI (r=-0.680,P ＜ 0.01).Multiple regression analysis indicated that eGFR had positive correlation with fetuin A (B=0.058,t=3.679,P＜ 0.01) and negative correlations with MPI (B=-0.511,t=-2.903,P=0.007),age(B=-0.144,t=-4.013,P＜0.01).Diabetes was risk factor to loss of RRF (B=-2.031,t=-2.759,P ＜ 0.05).Conclusion Fetuin A has very close relationship with left ventricular function.Decreased serum fetuin A level and decreased left ventricular function are risk factors to the loss of the RRF in ERSD patients.
