There is significant evidence to show that many neurosurgical patients with hyponatremia, who were previously diagnosed with syndrome of inappropriate antidiuretic hormone secretion(SIADH), actually have cerebral salt wasting syndrome(CSWS). The critical difference between SIADH and CSWS is that CSWS involves renal salt loss leading to hyponatremia and volume loss, whereas SIADH is a euvolemic or hypervolemic condition. The primary treatment for CSWS is water and salt replacement. The mechanisms underlying CSWS are not understood but may involve ANP or other natriuretic factors and direct neural influence on renal function.

Objective To compare the application value and the clinical curative effect of longitudinal incision and tarsal sinus minimal-ly invasive approach in treatment of patients with intra-articular calcaneal fractures. Methods A retrospective statistical analysis was made by collecting and comparing the clinical data of 67 patients with intra-articular calcaneal fractures from March 2008 to March 2012,and they were divided into the longitudinal incision minimally invasive approach group ( ZW group,36 patients,37 feet) and the tarsal sinus minimally invasive approach group ( FW group,31 patients,33 feet) . The Bohler angle, Gissane angle before and after operation,complications healing time,and AOFAS scores were compared. Results The healing time,Bohler angle,Gissane angle of ZW group and other indicators were better than those of the FW group,but there was no significant difference between the two groups (P>0. 05). The infection of incision and compli-cations in ZW group was obviously less than those of the FW group (P<0. 05). According to the AOFAS scoring system,ZW group scored 82. 49 points while FW group scored 86. 53 points,which indicated no statistical significance (P>0. 05). Conclusion The two kinds of treatments are of no obvious difference,but the longitudinal small incision minimally invasive approach could receive better effect in terms of soft tissue damage,healing time,and postoperative complications.

Objective To explore the effects of cognitive rehabilitation on aphasia for the patients with severe traumatic brain injury.
Methods 40 patients with traumatic brain injury following aphasia were randomly divided into simple language group (n=20) and language-
cognition group (n=20). Both groups received conventional therapy and language therapy, and the language-cognition group received
cognitive rehabilitation additionally, 30 minutes 1 day for 1 month. Results The index of Chinese Rehabilitation Research Center Aphasia
Examination (CRRCAE) improved significantly after treatment in both groups (P<0.01). There were significant differences in all the indexes
of CRRCAE (P<0.05) between 2 groups after treatment except dictation (P>0.05). Auditory comprehension correlated with orientation,
visual perception, spatial perception, motor praxis, visuomotor organization and thinking operations. Conclusion Cognitive rehabilitation
can improve the language function of traumatic brain injury patients with aphasia.

ObjectiveTo study the effects of rehabilitation training on the expression of brain derived neurotrophic factor(BDNF) around the cerebral infarcted area of rats.Methods60 SD rats were randomly divided into rehabilitation group and immobilization group 24 hours after cerebral infarction.The rehabilitation group were given water maze training,rotating bar and rolling cage exercises everyday while the immobilization group were fixed in cages. Histochemistry was used to detect the BDNF expression around the cerebral infarcted area at the 1st,3rd,7th,10th and 14th day after infarction respectively.ResultsAt 1st day after the infarction, the expression of BDNF increased obviously around the infarcted area in both group. More BDNF positive neurons were found in the rehabilitation group than that in the immobilization group at 3rd day (P<0.01). BDNF positive astrocytes showed obvious increasing in both group. BDNF positive neurons decreased with time going, and the color became lighter at the same time .At the 7th day after infarction, there were only a few positive neurons, and seldom obvious positive neurons could be seen around the infarcted area at 10th and 14th day. Great deal of BDNF positive astrocytes were found at 3rd,7th,10th and 14th day, and the rehabilitation group showed more expression than that of the immobilization group(P<0.01).ConclusionsThe rehabilitation training may increase the expression of BDNF which might take an active part in the recovery of the central nervous system injury and the rebuilding of its function.
