Objective To study the efficacy of sodium profile combined with ultrafiltration profile in preventing intradialytic hypotension and changes of the sodium level in blood plasma after hemodialysis. Methods 10 patients with maintenance hemodialysis were chosen randomly. Every patient underwent with conventional hemodialysis treatment and sodium profile combined with ultrafiltration profile treatment 5 times alternatively. And then the blood pressure changes. HR changes, ultrafiltration volume changes and clinical symptoms were observed during treatments. And also after HD, the sodium level in blood plasma was observed. Results The blood pressure decrease of sodium profile combined with ultrafiltration profile evidently reduced the conventional HD treatments( P＜0.01 ).Ultrafiltration volume of the former evidently increased compared with that of the latter(P＜0.01 ). The sodium level in blood plasma after HD was not significantly changed compared with before HD(P＞0.05). Conclnsion Sodium profile combined with ultrafiltration profile diminishes the episodes of hypotension evidently and increases the ability to endure sufferirgs to patients and does not increase the sodium level in blood plasma. So it is an effective medical treatment.

AIM:To investigate the peripapillary retinal nerve fiber layer ( RNFL ) thickness and the macular ganglion cell complex ( GCC ) thickness in primary open angle glaucoma ( POAG ) eyes and to compare them with normal control eyes, and to evaluate the diagnostic ability of peripapillary RNFL thickness and macular GCC thickness in POAG.
●METHODS:This was a cross-sectional study consisting of 56 POAG patients. The control group consisted of 60 normal subjects (60 eyes) were matched in terms of age, sex, diopter and axial length. The peripapillary RNFL thickness and the macular GCC thickness of POAG eyes and normal control eyes were measured and compared by RTVue-100 optical coherence tomography ( OCT ) . To assess the diagnostic utility of peripapillary RNFL thickness and macular GCC thickness in POAG, receiver operating characteristic curves ( ROC ) and areas under the ROC ( AUC) were used.
●RESULTS:The POAG eyes had a thinner peripapillary RNFL and macular GCC than the control eyes at all the regions ( P < 0. 001 ). Multivariable linear regression analysis showed that the peripapillary RNFL thickness and macular GCC thickness was significantly thinner in association with the POAG diagnosis. ROC and AUC analysis showed that the best AUC parameters were C/D (AUC=0. 936; 95% Cl=0. 903, 0. 964) and superior RNFL thickness (AUC=0. 910;95% Cl=0. 889, 9. 455). The AUC of nasal RNFL thickness, inferior RNFL thickness, temporal RNFL thickness, superior GCC thickness, inferior GCC thickness, and average GCC thickness were all above 0. 8 with a good diagnostic value.
●CONCLUSION:The peripapillary RNFL thickness and macular GCC thickness in POAG eyes are thinner than that of normal control eyes. Decreased peripapillary RNFL thickness and macular GCC thickness may be associated with POAG. The peripapillary RNFL thickness and macular GCC thickness have a good diagnostic value.

Objective To study COX-2 expression in bladder transitional cell carcinoma in order to explore the relationship between the immunohistochemical staining and biological behavior of bladder cancer. Methods The expression of COX-2,Ki-67,and VEGF was examined in 50 cases of bladder transitional cell carcinoma and 10 normal bladder mucosa by means of immunohistochemical technique.Results The expression of COX-2 in BTCCs was higher than that in normal bladder mucosa.The positive rate of COX-2 was 80% in BTCCs while it was not detected in normal bladder mucosa.COX-2 was highly positively related to the grade,stage and prognosis of tumors.The expression of COX-2 in poorly differentiated,invasive or re- curring BTCCs was higher than that in well differentiated superficial or nonrecurring ones.But there was not significant difference between the solitary tumour and multiple ones.There were positive correlation both be- tween COX-2 and Ki-67 and between COX-2 and VEGF.Conclusion The high expression of COX-2 may benefit increase in bladder cancer cell proliferative activity.VEGF expression in COX-2 positive tumor was significantly higher than that in COX-2 negative tumor.

Objective To investigate the mastery of clinical students' doctor-patient communi-cation skills and to assess the teaching effectiveness about the doctor-patient communication, and then propose some improvement ideas. Methods We conducted a study in students of clinical medicine of Nanjing Medical University in Grade 2009, using Objective Structured Clinical Examination (OSCE) after internship, which included graduation assessment of doctor-patient communication skills. Then we analyzed the doctor-patient communication skills and related scores of students trained in different clinical medical programs. Results The average score of doctor-patient communication skills of 549 students was (82.72±4.23), of which, the average score of 329 five-year students of clinical medicine was (81.88±4.23) and the average score of seven-year students was (83.96±3.91) in. The average score of seven-year students of clinical medicine was significantly higher than five-year students (P=0.000). Moreover, there was a significant positive correlation between the total score of OSCE and the score of doctor-patient communication skills in both five-year and seven-year students of clinical medicine (five year program students' score correlation coefficient was 0.520, P=0.000;seven year pro-gram students' score correlation coefficient 0.416, P=0.000). Conclusion The teaching effectiveness of doctor-patient communication has proved to be quite effective, and it is definitely of great significance in improving clinical students' doctor-patient communication skills. The score of the assessment of the doctor-patient communication reflects not only the training effectiveness of the communication skills, but also the comprehensive capacity.

Vascular endothelial growth factor(VEGF) is one of the best characterized angiogenic regulators which has many effects in promoting endotheliocyte proliferation and differentiation,increasing the microvascular permeability,inducing the angiogenesis,triggering the growth,survival and migration of tumor cells by combining its specificity receptor (VEGFR).Dysregulation of VEGF expression and signaling pathways therefore plays a pivotal role in the pathogenesis and clinical features of hematologic malignancies,direct and indirect targeting of VEGF and its receptors therefore may provide a potent novel therapeutic approach to overcome bone marrow angiogenesis and multidrug resis-tance thereby improve patient outcome.Recent years,a novel VEGF blockade system using RNA interference attracts more and more people's attention.The small interfering RNA (siRNA) targeting VEGF/VEGFR can completely inhibits the expression of VEGF and induce the silence of corresponding genes.
