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.

Objective To investigate the mechanism of inter fe ron-? (IFN?) in preventing hepatic fibrosis in rat experimental model . Methods Thirty-six male Sprague-Dawley rats were divide d into three groups randomly: group A(normal controls)of 12 rats were given norm al food and water and received subcutaneous injection of peanut oil twice weekly ; group B (fibrotic model)and group C (IFN? prevention) with 12 rats in eac h were induced by carbon terrachloride, high cholesterol and low protein. Group C were treated with intramusclular injections of IFN? in saline, administered daily at the doses of 1?10 5U. At the end of the sixth week, all the rats in each group were killed, the liver function was examined and the samples of t he liver obtained by biopsy were submitted to histological liver fibrosis studie s. The expressions of ?-smooth muscle actin in hepatic tissues were detect ed with immunohistochemical methods. The effect of IFN? on apoptosis of hep atic stellate cells (HSC) were investigated under electron microscope. Results The level of hepatic collagen Ⅰand Ⅲ and serum PC Ⅲ, HA, and LN in group C was significantly lower than that of group B under lig ht microscope (P

BACKGROUND:The post and core system for residual roots and crowns can achieve satisfactory effects, when fil ing restoration, ful crowns or inlay has poor effects. OBJECTIVE:To evaluate the clinical use of glass fiber post and metal post in the restoration of endodontical y treated teeth. METHODS:A total of 106 patients with 160 endodontical y treated teeth were selected and restored with glass fiber post (n=80 teeth) and metal post (n=80 teeth) fol owed by porcelain-fused-mental crown. The restorations were evaluated clinical y for 9 to 33 months. RESULTS AND CONCLUSION:Glass fiber post treatment for 78 teeth was effective and that for two teeth were failed, with a successful rate of 98%. Metal post restoration was effective in 71 teeth and failed in nine teeth including one tooth of crown fracture, four of root fracture and four of post loss, with a successful rate of 89%. There was statistical y significant difference between two groups (P<0.05). Glass fiber post is better in convenient handling and good color and reduced probability leading to root broken for dental restoration compared with metal post.

Bronchopulmonary dysplasia (BPD) is a respiratory disorder that is frequently associated with premature infants.Prevention from its occurrence is perceived to be more valuable than its treatment due to the current lack of effective management.This article elaborated recent development in preventing premature birth and lung injuries caused by mechanical ventilation,oxygen toxicity,infection and inflammation,which played a central role in the development of BPD.
