ABSTRACT
Objective To investigate the effects of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)on acute myocardial functional lesion after severe craniocerebral injury.Methods Sixty five examples with severe craniocerebral injury are collected in the 253th hospital of PLA from February in 2009 to May in 2012,of whom glasgow coma scale was low or equal to 8 points.They are examined creatine kinase-MB(CK-MB),cardiac troponin T(cTnT),TNF-αand IL-6 for correlative analysis while they are emer-gency treated at the same time.Results The myocardial function of the observe group examined results:CK-MB(198.63±37.72) U/L,cTnT(548.17±49.58)pg/mL;injury factors examined results:TNF-α(39.93± 18.88)ng/mL,IL-6(469.61 ±73.66)ng/mL.It both has evidently difference between the control group and the observe group and has obviously correlation between the my-ocardial function and injury factors of the observe group (P 0.911 4)and cTnT(r>0.942 1)had statistically significant difference.Conclusion TNF-αand IL-6 all participate in the process of the acute myocardial functional lesion after severe craniocerebral injury.The inchoate interference and treatment against TNF-αand IL-6 are possible to have inhibited the high expression of TNF-αand IL-6 in the blood and to improve the myocardial functional lesion after severe craniocerebral injury.
ABSTRACT
<p><b>BACKGROUND</b>Based on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.</p><p><b>METHODS</b>The Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.</p><p><b>RESULTS</b>A total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).</p><p><b>CONCLUSION</b>We first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.</p>

<p><b>OBJECTIVE</b>To study the effects of magnesium sulfate on brain mitochondrial respiratory function in rats after experimental traumatic brain injury and the possible mechanism.</p><p><b>METHODS</b>The middle degree brain injury in rats was made by BIM-III multi-function impacting machine. The brain mitochondrial respiratory function was measured with oxygen electrode and the ultra-structural changes were observed with transmission electron microscope (TEM).</p><p><b>RESULTS</b>1. The brain mitochondrial respiratory stage III and respiration control rate reduced significantly in the untreated groups within 24 and 72 hours. But treated Group A showed certain degree of recovery of respiratory function; treated Group B showed further improvement. 2. Untreated Group, treated Groups A and B had different degrees of mitochondrial ultra-structural damage respectively, which could be attenuated after the treatment with magnesium sulfate.</p><p><b>CONCLUSIONS</b>The mitochondrial respiratory function decreases significantly after traumatic brain injury. But it can be apparently improved after magnesium sulfate management along with the attenuated damage of mitochondria discovered by TEM. The longer course of treatment can obtain a better improvement of mitochondrial respiratory function.</p>
