Objective To clarify whether the mRNA expression level of glucocorticoid receptor (GR) in the peripheral blood mononuclear cells (PBMCs) can predict the clinical response to glucocorticoid (GC) in patients with pemphigus. Methods Reverse-transcription polymerase chain reaction (RT-PCR) was applied to determine the mRNA expression of GR? and GR? in PBMCs from 30 patients with pemphigus and 30 healthy volunteers. Results GR? mRNA was detected in all patients and all healthy volunteers, and the expression of GR? mRNA in pemphigus patients was significantly lower than that in healthy volunteers (P = 0.044), but no significant difference was found between patients insensitive and sensitive to glucocorticoid. In contrast, GR? mRNA was detected in 10 of 12 patients insensitive to glucocorticoid, 3 of 18 patients sensitive to glucocorticoid, and 9 of 30 healthy Volunteers. The positive rate of GR? in the insensitive group was significantly higher than that in the sensitive group (P

Objective To investigate whether the presence of sepsis associated encephalopathy (SAE) would predict nosocomial coma (NC) and poor outcome in patients with supratentorial intracerebral hemorrhage (SICH). Methods A retrospective cohort study was conducted. The adult acute SICH patients with or without coma admitted to intensive care unit (ICU) of Shuyang People' Hospital Affiliated to Xuzhou Medical University from December 2012 to December 2015 were enrolled. Brain computed tomography (CT) scans were analyzed and the patients were divided into pre-hospital coma (PC) and NC groups. The clinical data and the incidence of SAE of patients in two groups were compared, and the 30-day prognosis was followed up. Univariate and Cox regression analyses were performed to analyze whether SAE would predict NC and poor outcome in patients with SICH. Results A total of 330 patients with acute SICH and coma were enrolled, excluding 60 cases of infratentorial cerebral hemorrhage, 3 cases of primary intraventricular hemorrhage, and 6 cases of unknown volume hematoma. Finally, 261 patients were included, with 111 patients of NC events, and 150 patients of PC events. 69 (62.2%) SAE in SICH with NC and 33 (22.2%) SAE in SICH with PC was diagnosed, and the incidence of SAE between two groups was statistically significant (P < 0.01). Compared with PC group, SICH patients in the NC group had lower incidence of hypertension (81.1% vs. 96.0%), longer time from onset to NC [days: 2.3 (23.9) vs. 0 (0.5)] and length of ICU stay [days: 5.0 (34.0) vs. 3.0 (12.0)], higher initial Glasgow coma score (GCS, 10.2±1.5 vs. 6.6±1.6) and sequential organ failure assessment (SOFA) score [4.0 (6.0) vs. 3.0 (3.0)], lower initial National Institutes of Health Stroke Scale (NIHSS) score (19.4±6.6 vs. 30.2±6.8), as well as more frequent sepsis (78.4% vs. 38.0%), vegetative state (24.3% vs. 14.0%), acute respiratory failure (24.3% vs. 10.0%), pneumonia (37.8% vs. 24.0%), septic shock (8.1% vs. 0), acute liver failure (5.4% vs. 0), hypernatremia (8.1% vs. 0), CT indicating that more frequent vasogenic edema (64.9% vs. 16.0%) and white matter lesion (13.5% vs. 2.0%), and less mannitol usage (94.6% vs. 100.0%), and less brain midline shift (32.4% vs. 68.0%) and hematoma enlargement (8.1% vs. 30.0%), less hematoma volume (mL: 28.0±18.8 vs. 38.3±24.4) in CT, and higher 30-day mortality (54.1% vs. 26.0%) with statistical differences (all P < 0.05). It was shown by Cox regression analyses that SAE [hazard ratio (HR) = 3.5, 95% confidence interval (95%CI) = 1.346-6.765, P = 0.000] and SOFA score (HR = 1.8, 95%CI = 1.073-1.756, P = 0.008) were independent risk factors of death of SICH patients with NC, and hematoma enlargement was independent risk factor of death of SICH patients with PC (HR = 3.0, 95%CI = 1.313-5.814, P = 0.000). Conclusion SAE is the independent factor of inducing NC event and poor prognosis in SICH patients.

Objective To investigate whether the presence of infection in a case series with coma would predict sepsis associated encephalopathy(SAE).Methods From Jan 2013 to Oct 2014,we used the criteria of systemic inflammatory response syndrome (SIRS)positive sepsis with encephalopathy and retrospective diagnosed a comatose case series with infection and from a tertiary teaching hospital intensive care unit (ICU).Results Among 6 comatose patients with evidence of infection,3 cases were secondary infection after hemorrhagic stroke,1 case was secondary infection after trauma,and the other 2 cases were primary infection.All patients met the diagnosis of SIRS -positive sepsis with encephalopathy.Among them,the presence of SIRS 3 criteria was in 2 cases,four criteria in 4 cases. All patients with severe brain failure (100%),in addition to 5 cases with acute respiratory failure caused by lung injury,one case with acute liver failure.Brain imaging confirmed that the delayed vasogenic edema was in two cases (33.3%),the cerebral ischemic lesions in four cases(66.7%).The ischemic lesion included 1 patient with minor infarcts and 1 case with mild white matter lesions,and with a good prognosis.The other two ischemic cases included multifocal leukoencephalopathy with central pontine myelinolysis in 1 case and extensive white matter lesions in 1 case,eventually with a poor prognosis.Conclusion SAE is a common critically illness,the use of the new classifi-cation criteria of sepsis is helpful in the diagnosis of sepsis associated encephalopathy.
