Objective To investigate the effect of taurine transporter in the process of protection of brain edema in rats with severe traumatic head injury. Methods A total of 24 Male Sprague-Dawley rats were randomly divided into 4 groups. Except the control rats (Group Sham), all other three groups were subjected to lateral fluid percussion head injury. The TBI (Traumatic brain injury) models (Group TBI) and surgical control rats (Group Sham) were injected with saline through caudal vein after surgery, while the Taurine prevention and Taurine treatment models (Group Pre Tau and Group Tau) were injected with 120 g/L taurine solution before or after surgeries respectively. Water content in each brain, mRNA and protein expres?sion of aquaporin 4 and taurine transporter in the injured rat brain hemispheres were all evaluated over the time course of the study (7 d) in each group. Results Compared with rats in Group Sham, water content in each brain increase, mRNA tran?scription and protein expression of AQP4 were both up regulated but the mRNA transcription and protein expression of TauT were both down-regulated in rats in TBI group. Compared with rats in TBI group, brain water content, mRNA transcription and protein expression of AQP4 all decrease while mRNA transcription and protein expression of TauT all increase in rats in Pre tau and Tau groups. There is no statistical difference of TauT expression between rats in pre-tau group and Tau group. Conclusion Taurine exert its neuron protection role through draining water content from brain and down regulating expres?sion of AQP4 but rising expression of TauT after TBI.

Aim To investigate the changes of intracellular calcium in primary cultured neurons after fluid percussion injury under the effects of cerebrolysin.Methods The neurons of rats were divided into: normal group,FPI group and cerebrolysin group(0 h and 1 h treatment after fluid percussion injury(FPI)).The intracellular calcium([Ca2+]i) at rats neurons in 24 h and 48 h postinjury were measured by using the laser scanning confocal microscope under calcium fluorescent indicator Fluo-3/AM.Results The [Ca2+]i at rats neurons were markedly increased after 24 h postinjury compared with normal neurons and maintained the higher level after 48 h.Cerebrolysin,whenever added at 0h or 1h after FBI,could significantly decrease the rise of [Ca2+]i on 24 h postinjury,which only happened in 48 h postinjury by 1 h treatment after FPI.Conclusion Cerebrolysin has the protective effects on primary cultured rat cortical neurons of rats and has the time-window treatment.

prognosis of patients with acute upper gastrointestinal bleeding (AUGIB). Methods A total of 130 patients with AUGIB in our hospital were enrolled in this study from August 2014 to August 2016 . Three kinds of scoring systems including Rockall, Blatchford and AIMS65 were used to evaluate the risk classification of the patients. Patients were followed up for 2 months. The incidence rates of re-bleeding and death within 2 months after admission were observed. Data of prognosis in patients with AUGIB were compared between the three scoring systems in the prognosis of patients with AUGIB, including the risk classification and the prediction accuracy of re-bleeding and death. Results There were no significant differences in the re-bleeding rate and fatality rate between the groups divided by Rockall and Blatchford scoring systems ( P>0.05). According to the grouping results of AIMS65 scoring system, the re-bleeding rate of low-risk group was lower than that in high risk group (1.45%vs. 13.11%, P=0.01), but there was no significant difference in fatality rate between the two groups (P>0.05). The values of area under the curve (AUC) of predicting re-bleeding rates by using Rockall, Blatchford and AIMS65 scoring systems were 0.6258, 0.6910, and 0.7241, and the values of AUC of predicting fatality rates were 0.7031, 0.7969, and 0.7031 by using receiver operating characteristic curve (ROC) analysis. There were no significant differences between them (P>0.05). The values of AUC of predicting re-bleeding rates by using the risk grading calculation by Rockall, Blatchford and AIMS65 scoring systems were 0.6189, 0.6139 and 0.7254 (P>0.05). But the values of AUC of predicting fatality rates were 0.6211, 0.6641 and 0.7695 (P<0.01). Conclusion The operation method of AIMS65 scoring system is simple and convenient, which is applicable to a wide range of patients with AUGIB. In the prediction of re-bleeding and mortality, AIMS65 scoring system has high accuracy and stability, which is worthy of promoting in clinical application.
