Objective To assess the effect of atorvastatin on the Lipopolysaccharide (LPS)-induced cyclooxygenase-2 (COX-2) expression in cultured human pulmonary epithelial cells (A549). Methods A549 cells were incubated in the medium containing LPS and different concentrations of atorvastatin(0,10,15,20?M/ml, respectively) for 12h. Then the total cellular RNA and proteins from the cells treated with different experimental conditions were extracted for RT-PCR and western blot analysis,respectively. Results In cultured human pulmonary epithelial cells, atorvastatin reduced the expression of COX-2 mRNA and protein induced by LPS in a dose-dependent manner. Conclusion Atorvastatin may down-regulate LPS-induced COX-2 expression in cultured human pulmonary epithelial cells.

Objective The present study was undertaken to investigate the properties of nonlinear dynamics of EEG and the changes in depth of anesthesia with real-time approximate entropy (ApEn) and complexity (Cx) nonlinear indexes monitoring during anesthesia. Methods EEG was recorded in 65 in-patients. They were randomly divided into 4 groups: isoflurane, sevoflurane, desflurane (n=15, respectively), and propofol intravenous anesthesia (n=20) groups. The EEG derived parameters ApEn and Cx non-linear indexes were calculated simultaneously during the whole operation including rest state with eyes closed, anesthetic induction, intraoperation, recovery, post-operation awaking. Results ApEn and Cx nonlinear indexes remained the highest during rest state. Both of them kept decreasing during anesthetic induction. They dropped to a relative lower value and leveled off in the intra-operation period. Both of them rose gradually during recovery period and returned to a high level in the post-operation awaking period (correspondingly, ApEn: 0.87, 0.78, 0.55, 0.64 and 0.83. Cx: 0.58, 0.54, 0.38, 0.46 and 0.57). Conclusions With ApEn and Cx non-linear indexes, changes in depth of anesthesia from EEG signal could be real-timely monitored and precisely measured. Nonlinear dynamic analysis might provide us with more information about consciousness and cognition during general anesthesia.

Objective To investigate effect of mild hypothermia on changes of somatosensory evoked potential (SEP) and synaptophysin mRNA level after traumatic brain injury (TBI) and determine hypothermia-induced neuroprotection.Methods Forty-five SD rats were allocated into mild hypothermia group,TBI group and sham operation group with 15 rats per group according to the random number table.Left-side fluid percussion impact was performed to induce models of TBI.Rats were exposed to hypothermia environment (32-35℃) for 6 hours in mild hypothermia group after TBI.Rats in sham operation group were treated by only drilling on left side of the head,rather than hitting.To evaluate function outcome,modified neurological severity score (mNSS),SEP and synaptophysin mRNA level were measured at 6 hours,24 hours and 7 days postinjury.Results The mNSS in mild hypothermia group lowered compared with TBI group,especially at 24 hours and 7 days (P ＜ 0.05).SEP in mild hypothermia group was significantly shortened at 6 and 24 hours compared with TBI group (P ＜ 0.05),but SEP revealed no significant difference among the 3 groups at 7 days (P ＞ 0.05).Level of synaptophysin mRNA in mild hypothermia group increased at 6 hours postinjury compared with TBI group [(0.08 ± 0.02) vs (0.12 ±0.04)],with further increase at 7 days postinjury[(0.06 ± 0.01) vs (0.33 ± 0.10)] (P ＜0.05).Conclusion The shortage of nerve conduction time of the injured side and promotion of nerve regeneration suggest the neuroprotective role of mild hypothermia following TBI.

Purpose To investigate the clinicopathologic features, diagnosis and differential diagnosis of ovarian juvenile granulosa cell tumor (JGCT).Methods The history records, pathologic features and immunophenotype of 8 cases of JGCT were retrospectively evaluated and their prognosis was achieved by follow-up.Results The age of patients ranged from 6～21 years old,with an average age of 15.1 years.The main clinical manifestations included an abdominal mass, ascites and isosexual pseudoprecocity. Cut surface of the tumor was typically solid with cysts formed. The histopathological changes displayed solid nests, diffuse sheet, multiple round or ovoid follicles in variable size.Macrofollicles could be seen in some cases.The follicular pattern consisted of small cystic cavities containing eosinophilic secretions. The tumor cells were round or polygonal, medium in size. The tumor cells had abundant pale or slightly eosinophilic cytoplasm, round nuclei with fine chromatin. Nuclear grooves were inconspicuous.Mitosis figures could be found. Immunohistochemical results showed that the tumor cells expressed inhibin-α,CD99,vimentin; while Melan-A,calretinin and S-100 were positive staining in part of the cases.CKpan,EMA,PLAP,Syn and CgA were negative in all the cases.Conclusions Ovarian juvenile granulosa cell tumor is a rather rare, low malignant tumor with good prognosis. Its diagnosis depends on the histologic and immunohistochemical findings and clinical features. Its differential diagnosis includes adult granulose cell tumor, hypercalcaemic type small cell carcinoma, carcinoid and dysgerminoma.

Objective To investigate effect of taurine on respiration chain enzyme activity of mitochondria 24 hours after severe traumatic brain injury (TBI) in rats.Methods Fifty-six SD rats were divided into sham group,TBI group,taurine treatment group,and taurine prevention group according to the random number table,with 14 rats per group.Fluid percussion brain injury models were used.Via the caudal vein,normal saline was administered to animals in sham and traumatic brain injury groups immediately after injury,while taurine (200 mg/kg)was administered to animals in taurine treatment group after injury and in taurine prevention group 4 days before injury.Brains were harvested 24 hours postinjury for assays of HE staining and electron microscopy.Mitochondrial respiratory chain complex Ⅰ-Ⅴ activities were detected.Results TBI group presented swelling neurocytes,cell loss,karyopyknosis,shortened even vanished process,and inflammation cell infiltration at the edge of necrosis in HE staining.By contrast,morphological improvement was significant in taurine treatment group but only some neurons were intact in taurine prevention group.Swelling mitochondria and broken or vanished mitochondrial crests were seen in TBI group under the electron microscope.However,normal or minor swelling mitochondria was seen in taurine treatment group and cytoplasm slightly porous and absence of mitochondrial crests were seen in taurine prevention group.Activities of complex Ⅰ,Ⅱ and Ⅴ were significant lower in TBI group (32.52±2.41,4.68 ±0.15,2.49 ±0.73) compared to those in sham group (34.03 ±0.46,5.04 ±0.29,3.20±0.68) and in taurine treatment group (33.95±0.85,5.12-±0.23,3.53 ±0.48) (P＜0.05).And complex Ⅰ in taurine prevention group was significantly enhanced as well (34.44 ± 0.36,P ＜ 0.05).Conclusion Taurine may protect the brain tissues and mitochondrial structure from impairment in TBI rats by improving mitochondrial enzymes activity and reducing secondary energy loss.

Objective To investigate the effect of mild hypothermia on neuroprotection and prognosis prediction of rats with traumatic brain injury (TBI) by dynamically monitoring the somatosensory evoked potentials (SEP) and quantitative electroencephalogram (QEEG).Methods Forty healthy adult male SD rats were randomly divided into four groups according to random number table,ie,normal control group (with no intervention),sham operation group (fenestration only,without drilling),TBI group (fluid percussion was used to produce moderate to severe TBI),and mild hypothemia group (ice blanket was used immediately after TBI for continuous physical cooling and rectal temperature was maintained at 32-35℃ and rewarmed to 37℃ 6 hours after the initiation of cooling),with 10 rats per group.Changes of SEP and QEEG in all groups were monitored at 6,24 hours,and 7 days after TBI.Results (1) Compared with TBI group,the latency of SEP waves (P1 and N1) on the injured side in mild hypothemia group began to shorten at 24 hours(P ＜ 0.05) and were close to that in the sham operation group at 7 days.(2) Except for normal control group and sham operation group,QEEG in TBI group showed decrease of α rhythm,increase of reactivity slow waves,and decrease or disappearance of QEEG relative power spectral values at all time points.In mild hypothermia group,the reactivity slow waves were decreased with a small amount of α wave; QEEG relative power spectral values were increased at 24 hours and 7 days (especially at 24 hours),but werc still lower than those in normal control group (P ＜ 0.05).Conclusion Mild hypothermia exerts neuroprotective effect through reducing SEP latency,raising relative power spectral values of QEEG,and improving the nerve conduction and brain electrical activity of the injured side.

Objective To stuay CT findings of adrenal gland trauma(AGT).Methods The CT images of adrenal gland trauma which were found in 1712 patients who had emergency abdominal CT examinations for assessment of blunt force trauma were analyzed restrospectively.Results Among 1712 cases.we identified 29 patients(1.7%)with adrenal gland traumatic lesions.A total of 32 lesions were found.Twenty-six lesions were unilateral(23 right-sided,3 left-sided),and 3 cases were bilateral(6 lesions).Main CT findings were as followed:(1)Adrenal hematomas appeared as discrete round or oval masses expanding the adrenal gland in 22 patients with 25 lesions.The lesions were hyperdense or of homogeneous density in plain scan and did not enhance in three-phase contrast-enhanced dynamic scan.The splayed adrenal limbs around hematoma were enhanced significantly as eurvilinear structures.(2)Mild to moderate uniform swelling of gland was shown in 4 cases.(3)Diffuse irregular hemorrhage obliterating the gland was shown in 3 cases.Contrast extravasation was shown in 1 case,which was active bleeding from the broken adrenal gland proven by operation.Associated CT findings included strand-like hemorrhage of the periadrenal fat and posterior pararenal hemorrhage mimicking thickened diaphragmatic crus.The concurrent injuries of ipsilateral thorax or/and abdomen were found in 25 patients.Conclusion The AGT has typical CT findings.Familiarity with characteristic CT findings of adrenal trauma is essential for the radiologist to avoid misdiagnosis.
