Guidelines for the Management of Severe Traumatic Brain Injury (Fourth Edition) have received extensive attention both at home and abroad after releasing by the Brain Trauma Foundation of the United States in 2016. The interval between the published newest version of the Guidelines and the Third Edition has already approached 7 years. In accordance with more rigorous evidence-based medicine standards, the Fourth Edition includes 94 updated research findings as evidence, in combination with the proposition of more accurate treatment recommendations and problem solutions. Combining the domestic situation and problems in the treatment of severe traumatic brain injury at present, three most important clinical issues related to the Fourth Edition of the guidelines are interpreted and analyzed in the present study, including decompressive craniectomy, mild hypothermia therapy and intracranial pressure monitoring, so as to improve the level of treatment of traumatic brain injury in China.

Objective To invesgate the effects of comfort care on the quality of life and the curative compliance of elderly patients undergoing hemodialysis.Methods Forty-nine elderly patients undergoing hemodialysis were managed with comfort care including comfortable settings,mental care,and care to arteriovenous fistula and intubated tubes,observation of complications and the related care.The Short Form 36 Health Survey Questionnaire(SF-36)and questionnaire on medical compliance were used for the assessments.Result The scores on SF-36 and medical compliance were both significantly higher than those before the manipulation of comfort nursing(P<0.05).Conclusion Comfort care may be helpful for the improvement of the quality of life and the medical compliance of hemodialysis in elderly patients undergoing hemodialysis.

Objective To discuss the effect of invasive intracranial pressure (ICP) monitoring in treating traumatic brain injury (TBI).Methods A total of 116 patients with TBI (including 112 with severe TBI,3 with moderate TBI and 1 with slight TBI) were monitored by using invasive ICP monitoring device in Tiantan Hospital from July 2003 to December 2007.All patients underwent ICP monitoring within first 24 hours after admission and treated with corresponding therapy including drug therapy and surgical treatment.Results Of all,74 patients survived but 42 with severe TBI died.Of 75 patients with GCS 3-5,33 died,with morbidity rate of 44%.Of 37 patieats with GCS 6-8,nine died,with morbidity rate of 24%.Four patients with GCS 9-15 survived.Conclusions Continuous ICP monitoring can help timely understanding of ICP changes for early diagnosis and correct treatment of TBI and is useful for judgment of prognosis.Low GCS and high ICP are predictors for bad outcome.

AIM: To explore the mechanism of myocardium protection after ischemia/reperfusion (I/R) injury by preconditioning with ischemia in human. METHODS: Thirty - six patients underwent valve replacement were divided into ischemic preconditioning group (IP group, 20 cases) and non -ischemic preconditioning group (control group, 16 cases) according to whether they were given single cycle reperfusion before cardioplegia or not. Serum levels of interleukin -8 and 10 were measured with ELISA. Expressions of myocardial Bel -2 and caspase -3 were analyzed. RESULTS: The inflammatory factors IL - 8 and IL - 10 increased to the highest level in serum at 6 h after declamping and recovered to normal level on 5 d after declamping. On 6 h, 1 d and 2 d after declamping, serum level of IL -8 was significantly lower in IP group than that in control group ( P < 0.05 ) , but serum level of IL -10 was higher in IP group (P < 0.05 ). Expression of myocardial Bel - 2 and caspase - 3 increased in both groups after reperfusion, and Bel - 2 was lower in the control group than that in IP group while the level of caspase - 3 was higher (P < 0.05). Expression of myocardial Bel - 2 had positive correlation with IL - 10 and negative correlation with IL - 8.CONCLUSION: Ischemic preconditioning has the effect of protection of human myocardial cells after ischemia/reperfusion injury through decreasing systemic inflammatory response following ischemia reperfusion injury.

Objective To investigate the role of poly(ADP-ribose) polymerase (PARP) inhibitor PJ34 in regulating blood-brain barrier (BBB) permeability and matrix metalloproteinases-9 (MMP-9) expression in a mouse model of traumatic brain injury (TBI).Methods A total of 136 adult male BALB/c mice were randomly divided into sham-operated group,injured group and PJ34-treated group according to the random number table.Controlled cortical impact in mice was established.At 6 and 24hours postinjury,neurological deficit was evaluated,including motor,sensory,reflex and beam balance tests ; BBB permeability and brain water content were detected using Evans blue test and gravimetric technique; brain contusion volume was measured using HE staining; levels of MMP-9 in cytosolic fractions were detected using Western blotting.Results At 6 and 24 hours postinjury,neurological severity score in PJ34-treated group (8.00 ± 0.26,7.50 ±0.25) were lower than those in injured group (12.50 ±0.39,11.80 ± 0.32) ; brain contusion volume in PJ34-treated group [(11.25 ± 0.91) mm3,(13.55 ±1.06) mm3] was lower than those in injured group [(25.37 ± 1.75) mm3,(28.24 ± 1.51) mm3] ; BBB permeability in PJ34-treated group [(440.08 ± 3.10) μg/mg,(860.46 ± 3.86) μg/mg] was lower than those in injured group [(936.96 ± 4.71) μg/mg,(1 302.23 ± 5.89) μg/mg] (all P ＜ 0.01).Brain water content lowered significantly in PJ34-treated group than in injured group at 6 hours postinjury [(80.77 ± 0.76) ％ vs (82.55 ± 0.73) ％,P ＜ 0.0l],but between-group difference was not significant at 24 hours postinjury.Lower levels in MMP-9 were also observed in PJ34-treated group compared with injured group at 6 and 24 hours postinjury(P ＜ 0.05 or 0.01).Conclusion PARP inhibitor PJ34 can attenuate MMP-9 up-regulation,inhibit BBB injury and hence protect the brain against TBI in mice.

Objective To investigate the relationship between the quality of life and different frequency of sudden death in Yunnan unexplained sudden death disease area.Methods According to the stratified cluster sampling method,728 individuals were selected as the respondents in Heqing County,Eryuan County of Dali Bai Autonomous Prefecture,and in Dayao County of Chuxiong Yi Autonomous Prefecture.According to the random sampling,649 individuals were selected as the control in Yongping County,Dali Bai Autonomous Prefecture.Data of the quality of life (WHOQOL-BREF version) were collected through household surveys.Analysis method including ANOVA,Chi-squared test and multilinear regression were used.Results Compared with the control population,the household income of population in the diseased area was not significantly different statistically (x2 =7.052,P ＞ 0.05).But the differences in education level and chronic disease situation were statistically significant (x2 =35.727,9.810,all P ＜ 0.05).According to the frequency of the sudden death,from one to four,the total scores of the quality of life,the scores of the physiology domain,the scores of the psychological domain,the scores of the environmental domain and the scores of the social relations domain (1 time:54.30,13.74,14.43,11.21,14.91;2 times:54.75,13.86,14.65,11.12,15.10;3 times:52.40,13.21,13.76,11.00,14.41;4 times:49.21,12.15,12.54,9.87,14.64)were all lower than those of the control group (56.03,14.11,14.78,11.88 and 15.26),the differences between two groups were statistically significant (x2 =41.88,25.75,41.07,35.07,8.08,all P ＜ 0.05);the total scores and each domain score of the quality of life were negatively correlated with the frequency of sudden death (the multi-variables regression coefficient were as follows:-1.195,-0.341,-0.356,-0.314,and-0.185,all P ＜ 0.05).Conclusions The quality of life of those who have lived in Yunnan unexplained sudden death area is associated with the outbreak frequency of sudden death.Following increasing of the outbreak frequency of Yunnan unexplained sudden death,the quality of life of the population living in Yunnan unexplained sudden death area has decreased.

Objective To investigate the impact of high intra-abdominal pressure on intracranial pressure in patients with traumatic brain injury and discuss the clinical significance of abdominal decom-pression. Methods Intra-abdominal pressure and intracranial pressure of 15 patients with abdominal trauma and brain injury were observed to discuss changes of intracranial pressure after abdominal decom-pression. Results After abdominal decompression, all patients got lower intracranial pressure, with decrease of (15.2±3.6) mm Hg. Conclusion Intra-abdominal pressure does affect intracranial pres-sure for patients with abdominal trauma and brain injury. Abdominal decompression may be effective for high intracranial pressure.

Objective To explore the value of fluid-attenuated inversion recovery (FLAIR)sequence and gradient echo T2 ?weighted image (GRE-T2 ? WI)in diagnosis of acute traumatic extra-axial hemorrhage.Methods 50 patients who were diagnosed as acute traumatic extra-axial hemorrhage by plain CT underwent FLAIR and GRE-T2 ? WI in acute stage.The diagnosis consistency (Kappa ),detection rate of subarachnoid hemorrhage(SAH),epidural hemorrhage(EDH)and subdural hemorrhage(SDH)were compared.The detection rates of SAH in 8 locations among FLAIR,GRE-T2 ? WI and combination of two sequences were analyzed by Chi-square test.Results 48 patients were enrolled in the study.The diagnosis consistency of SAH between FLAIR and GRE-T2 ? WI was high (k =1.0).The detection rate of SAH was 100% for both FLAIR and GRE-T2 ? WI.Comparing with GRE-T2 ? WI and combi-nation of two sequences,FLAIR tended to misdiagnose SAH in perimesencephalic cistern (P <0.05).The diagnosis consistency of EDH between FLAIR and GRE-T2 ? WI was high (k =1.0).3 patients with EDH were all detected by FLAIR and GRE-T2 ? WI. The diagnosis consistency of SDH between FLAIR and GRE-T2 ? WI was high (k =0.943).The detection rate of 12 patients with SDH was 100% in FLAIR,and 1 patient with SDH was missed by GRE-T2 ? WI.Conclusion The detection rate of acute traumatic extra-axial hemorrhage is high for both FLAIR and GRE-T2 ? WI.Combination of two sequences can improve the accuracy of acute traumatic extra-axial hemorrhage in clinic.

Objective To investigate the distribution characteristics of pathogens isolated fromcerebrospinal fluid of neurosurgical patients with intracranial infection following open craniotomy and thetherapeutic effect influenced by these pathogens,in order to give a reference to the clinical treatmentmeasures.Methods A retrospective analysis was made on the pathogen distribution and therapeuticeffect of 43 patients with intracranial infection and positive cerebrospinal fluid cultures after open cranioto-my from May 2007 to May 2013.Cerebrospinal fluid was cleared using the intraventricular catheter orlumbar catheter combined with intraventricular (ventricular irrigation) or intraspinal (intrathecalirrigation) injection of antibacterial agents.Results To test bacteria in cerebrospinal fluid pathogencultures,34 cases were infected with single strain (26 Gram-positive bacteria and 8 Gram-negativebacteria) and 9 cases had mixed infection with multiple strains.Fifty-two pathogen strains were isolated,including 32 (62％) Gram-positive bacteria,18 (35％) Gram-negative bacteria,2 (4％) fungi.A totalof 29 cases were cured (67％),7 improved (16％),and 7 ineffective (16％).Conclusions Cere-brospinal fluid pathogen infection is primarily Gram-positive bacterial infection,usually staphylococcusepidermidis and staphylococcus aureus.Gram-negative pathogens are acinetobacter,klebsiella,andpseudomonas aeruginosa.Ventriculoperitoneal shunting surgery and craniocerebral surgery are often asso-ciated with mixed infection of pathogens.Ventricular irrigation allows better results than intrathecal irriga-tion.Indications of intrathecal irrigation treatment used to control intracranial infection after ventriculoper-itoneal shunting surgery and craniocerebral surgery should be strictly performed.
