1.Systemic inflammatory response syndrome following acute brain injury
Journal of Medical Postgraduates 2003;0(09):-
Acute brain injury is usually complicated by systemic inflammatory response syndrome (SIRS) which is initiated by cytokines and inflammatory mediators and induces a series of adverse physiological changes, culminating in the development of multiple organ failure. SIRS plays a pivotal role on the function of brain and extra cerebral organs, exacerbates the brain edema, and increases the septic rate. The diagnostic criteria and pathological courses of SIRS, and its relationship with acute brain injury and sepsis are briefly reviewed.
2.The metabolic response to traumatic brain injury and implications for nutritional support
Parenteral & Enteral Nutrition 1997;0(04):-
The metabolic response to traumatic brain injury includes hypermetabolism, hypercatabolism, hyperglycemia, acute phase response and immunosuppression, which are mediated mainly by hypothalamus pituitary adrenal axis and cytokines. Sufficient nutritional support and appropriate metabolic intervention are believed clinically to play an important role on the mitigation of secondary brain damage, reduction of septic rate and improvement of patient′s outcomes.

Objective To study the expression and signiifcance of phospholipid transfer protein (PLTP) and macrophage migration inhibitory factor (MIF) in mice with bronchopulmonary dysplasia (BPD). Methods Ninety-six 4-day-old mice were randomly divided into oxygen group and air group. Mice in oxygen group were exposed to a FiO2 of 65%, and mice in air group were exposed to air. On day 7, 14, 21 and 28, blood and lung tissue samples from 12 randomly selected mice in each group were obtained. The serum levels of MIF and PLTP were measured by ELISA assay. The morphological changes of lung tissue were ob-served with HE staining. Results The mice in oxygen group showed thickened lung parenchyma and obvious pulmonary ifbrosis. The radioactive alveolar count was signiifcantly lower in oxygen group than that in air group (P<0.01). PLTP level in air group was increased gradually from day 7 to day 21, and began to decrease on day 28. PLTP level in oxygen group was increased from day 7 to day 14, and decreased on day 21 and day 28. MIF level in air group did not change during the experiment. MIF level in oxygen group was signiifcantly increased from day 7 to day 21, and began to decrease on day 28. Conclusions MIF and PLTP may be good biomarkers for the diagnosis of BPD.

Objectives: The aim of the current study was to explore the alterations of intestinal mucosa morphology and barrier function, and to determine how rapidly impairment of gut barrier function occurs and how long it persists following traumatic brain injury. Methods: Male Wistar rats were randomly divided into six groups (6 rats each group) including controls without brain injury and traumatic brain injury groups at hours 3, 12, 24, 72 and days 7. The intestinal mucosa structure was detected by histopathological examination and electron microscopy. Gut barrier dysfunction was evaluated by detecting serum endotoxin and intestinal permeability. The level of serum endotoxin and intestinal permeability were measured by using chromogenic limulus amebocyte lysate and lactulose/mannitol (L/M) ratio, respectively. Results: After traumatic brain injury, the histopathological alterations of gut mucosa occurred rapidly as early as 3 hours and progressed to a serious state, including shedding of epithelial cells, fracture of villi, focal ulcer, fusion of adjacent villi, dilation of central chyle duct, mucosal atrophy, and vascular dilation, congestion and edema in the villous interstitium and lamina propria. Apoptosis of epithelial cells, fracture and sparseness of microvilli, loss of tight junction between enterocytes, and damage of mitochondria and endoplasm were found by electron microscope. The villous height, crypt depth and surface area in jejunum decreased progressively with the time of brain injury. The level of serum endotoxin and L/M ratio were significantly higher in traumatic brain injury groups than that in control (P

Objective To investigate the expression of pSTAT5 in 7 pancreatic carcinoma cell lines,and the change of expression of pSTAT5 in pancreatic carcinoma cells SW1990 after growth hormone (GH) treatment, and explore its molecular mechanism. Methods Human pancreatic carcinoma cell lines (SW1990, Cap-1, Colo, Mia, AsPc, P3, PANC1) were cultured in vitro, and Western blotting was used to detect the expression of pSTAT5 in these cell lines. SW1990 in exponential growth phase was collected and nude Balb/c mice were inoculated with SW1990 cells. When tumors became palpable after inoculation, mice (normal saline group). 1 h, 2 h and 24 h after the last dose of GH treatment, the mice were sacrificed.Western blotting was used to detect the expression of pSTAT5 in SW1990 and inoculation tumor cells after GH injection. Results Positive expression of pSTAT5 was observed in all human pancreatic carcinoma cell lines (SW1990, Cap-1, Colo, Mia, Aspc, P3, PANC1). 5 minutes after GH (50 ng/ml) stimulation, the expression of pSTAT5 in SW1990 was 0.57 ±0.05, which was significantly increased; and it reached 0.64 ±0.04 at 10 minutes, then decreased to 0.39 ±0.03 at 15 minutes, however, it remained higher than that in the control group at 1 h (0.33 ± 0.02 vs 0.25 ± 0.06), and its expression at 2 h was 0.26 ± 0.03 and returned to the normal level. The expression of pSTAT5 in xenograft was not significantly changed. Conclusions GH could rapidly up-regulate the expression of pSTAT5 in SW1990 but the effect lasted for a relatively short period. GH had no significant effect on the expression of pSTAT5 in xenograft.

Objective To investigate the physical and mental development of small and appropriate for gestational age preterm infants in their early life. Methods This study recruited 220 preterm infants, who were discharged from our hospital and visited preterm following-up clinic at regular intervals from February 2009 to December 2012. All of those infants were divided into two groups based on whether their birth weight below 10th percentile for their gestational ages or not. Weights, lengths and head circumferences were measured up to seventh month age adjusted by gestational age. Meanwhile, mental tests were conducted by the professional staffs working on the children developmental assessment at their adjusted months of 5th, 6th or 7th. All of physical and mental scores were compared between the two groups. Results The SGA group was statistically less than the AGA group on the Z-score of weights from the ifrst to sixth month adjusted by gestational age (P<0.05). The difference disappeared on the seventh adjusted month age (P>0.05). The SGA group was statistically less than the AGA group on the Z-score of lengths from the ifrst to iffth month adjusted by gestational age (P<0.05). The difference disappeared on the sixth and seventh adjusted month age (P>0.05). The SGA group was statistically less than the AGA group on the Z-score of head circumferences from the ifrst to seventh month adjusted by gestational age (P<0.05). The SGA babies scored statistically less than the AGA babies with a mean development quotient score of 96.7 and 102.9, respectively (P<0.05). The scores of movement, cognitive, language in the SGA group were statistically less than those in the AGA group(P<0.05). Conclusions Preterm SGA could achieve satisfactory weight catch-up gain, with a decreasing difference from preterm AGA while they were getting older. But the length catch-up growth of preterm SGA seemed unsatisfactory with a big differece from preterm AGA. There was the worst catch-up on head circumference in those preterm SGA, backward in mental development, particularly in their movement, cognitive and language capacity.
