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 compare the 96-week efficacy of de novo combination therapy with lamivudine ( LAM ) and adefovir dipivoxil (ADV) to that of optimization monotherapy for chronic hepatitis B (CHB).Methods A total of 155 CHB patients were collected from the First Affiliated Hospital of Anhui Medical University during 2007 and 2009.All patients were randomly assigned to LAM monotherapy group ( n =53 ),ADV monotherapy group ( n =50 ) or LAM with ADV combination group ( n =52 ) according to randomized digital table.The liver and kidney functions,HBV serum markers,and HBV DNA loads were tested every 24 weeks.If patients in LAM or ADV group had poor response or virological breakthrough,they were given optimized therapy with ADV or LAM at week 24,48 or 72.One-way ANOVA (normal distribution and homoscedasticity ) and non-parametric test (non-normal distribution ) were performed to compare measurement data among groups.The impact factors of early virological response were analyzed by binary Logistic regression method.Results At week 24,the complete virological responses in LAM group,ADV group,and LAM + ADV group were 66.0％ ( 35/53 ),34.0％ ( 17/50 ) and 90.4％ ( 47/52 ),respectively (x2 =35.282,P ＜ 0.01 ) ; while,at week 96 the complete virological responses in three groups were96.2％ (51/53),86.0％ (43/50) and 100.0％ (52/52),respectively (x2 =19.115,P＞0.05).At week 96,the cumulative recover rates of ALT in LAM group,ADV group,and LAM + ADV group were 86.8％ (46/53),82.0％ (41/50)and 94.2％ (49/52),respectively (x2 =3.613,P ＞0.05);however,the ALT levels in three groups were statistically different (x2 =11.195,P ＜ 0.01 ).At week 96,the HBeAg seroconversion rates in LAM group,ADV group,and LAM + ADV group were 31.3％ ( 10/32),20.7％ ( 6/29 ) and 38.7％ ( 12/31 ),respectively (x2 =2.313,P ＞ 0.05 ).Early virological response was not found in I patient in LAM group and 19 patients in ADV group; virological breakthrough occurred in 11 patients in LAM group and 1 patient in ADV group.All patients in LAM + ADV group had early virological responses and had no virological breakthrough.Logistic regression showed that complete virological response at week 24 was correlated with the baseline HBeAg,the initial treatment and HBV DNA load.Layered evaluation showed that there were significant differences in early complete virological responses among three groups for patients with positive HBeAg,HBV DNA ＞ 6.28 × 106 copies/mL and ALT ≤5 ×ULN (x2 =7.726,10.921 and6.100,P＜0.05 or ＜0.01) ; for those with HBV DNA ＞6.28 × 106copies/mL,complete virological response was not observed in ADV group treated for 24 weeks.Conclusion LAM combined with ADV has stronger antiviral activity,lower resistance rate and can improve liver function and virological response,especially for the patients with HBeAg-positive,high HBV DNA loads and ALT ≤5 × ULN.
