Objective Hypercellularity in proliferan've glomerulonephritis can result from either increased proliferation or the failure of cells to undergo apoptosis in response to stimuli. Increasing evidence supports that alterations in the control of cell survival are important in the pathogenesis of proliferative glomerulonephritis. Methods Apoptotic cells in the glomeruli have been analyzed by the in situ end labeling (ISEL) of TdT from patients diagnosed with membranoproliferative glomerulonephritis (MPGN, n = 12), type IV lupus nephritis (LN, n = 15) and acute postinfectious glomerulonephritis (APGN, n = 13) in the present study. In addition, the proliferating cell nuclear antigen (PCNA)-positive proliferating glomerular cells were observed by immunochemical 4 layer PAP method in these patients. Results The ratio of proliferating and apoptotic cells was the highest one in patients with MPGN (3.91) as compared to APGN (1.28) and LN(1 .02). The extends of increasing apoptotic cells in the glomeruli were different among patients with MPGN,, APGN and LN, although all of them showed extremely glomerular hypercellularity. The number of apoptotic glomemlar cells was significantly higher in patients with APGN (1.16?0.35) than those with MPGN (0.12?0.16) as well as LN patients (0.35 ? 0.20). Conclusion Apoptosis is essential in the resolution of glomerular cellularity together with the remodeling processes. Intense proliferations without increment in apoptosis are the characterisitics of MPGN and LN associated with their renal histological changes and prognosis.

Objective To investigate the effct of continuous blood purification(CBP)on endotoxin receptor and signal transduction of patients with multiple organ dysfunction syndrome(MODS).Methods Thirty patients with MODS were selected and treated with low volume and high volume haemofiltration.Plasma level of TNF-?、IL-6 were messured before and after CBP at 6h,1d,3d.Express of PMN CD14mRNA,CD14 protein and activity of NF-?B were also observed.Results CBP had no effect on TNF-?,and plasma IL-6 decreased significantly(P

OBJECTIVETo explore genetic relationships of the 39 materials in six species of Curcuma.

METHODThe peroxidase isozyme (POD) and esterase isozyme (EST) were studied using vertical slab polyacrylamide gel electrophoresis (PAGE) technique, and the zymograms were analyzed using the software of NTSYSpc2. 1.

RESULTThe interspecific zymogramatic differences were obvious. Each species possessed its own specific zymogram distinguishing form the others. In the analysis of EST isozyme, C. phaeocaulis, C. wenyujin, C. kwangsiensis and C. chuanhuangjiang had their own specific zymogram. In the analysis of POD isozyme, just C. phaeocaulis and C. kwangsiensis had their specific zymogram.

CONCLUSIONThe genetic relationships are not associated with the geographical distributions and the genetic relationship between C. longa and C. sichuanensis are very close.

Radiologists and trauma surgeons should monitor for early killers among patients with thoracic trauma, such as tension pneumothorax, tracheobronchial injuries, flail chest, aortic injury, mediastinal hematomas, and severe pulmonary parenchymal injury. With the advent of cutting-edge technology, rapid volumetric computed tomography of the chest has become the most definitive diagnostic tool for establishing or excluding thoracic trauma. With the notion of “time is life” at emergency settings, radiologists must find ways to shorten the turnaround time of reports. One way to interpret chest findings is to use a systemic approach, as advocated in this study. Our interpretation of chest findings for thoracic trauma follows the acronym “ABC-Please” in which “A” stands for abnormal air, “B” stands for abnormal bones, “C” stands for abnormal cardiovascular system, and “P” in “Please” stands for abnormal pulmonary parenchyma and vessels. In the future, utilizing an artificial intelligence software can be an alternative, which can highlight significant findings as “warm zones” on the heatmap and can re-prioritize important examinations at the top of the reading list for radiologists to expedite the final reports.

OBJECTIVE: To compare the ancillary CT findings between superior mesenteric artery thromboembolism (SMAT) and superior mesenteric vein thrombosis (SMVT), and to determine the independent CT findings of life-threatening mesenteric occlusion. MATERIALS AND METHODS: Our study was approved by the institution review board. We included 43 patients (21 SMAT and 22 SMVT between 1999 and 2008) of their median age of 60.0 years, and retrospectively analyzed their CT scans. Medical records were reviewed for demographics, management, surgical pathology diagnosis, and outcome. We compared CT findings between SMAT and SMVT groups. Multivariate analysis was conducted to determine the independent CT findings of life-threatening mesenteric occlusion. RESULTS: Of 43 patients, 24 had life-threatening mesenteric occlusion. Death related to mesenteric occlusion was 32.6%. A thick bowel wall (p < 0.001), mesenteric edema (p < 0.001), and ascites (p = 0.009) were more frequently associated with SMVT, whereas diminished bowel enhancement (p = 0.003) and paralytic ileus (p = 0.039) were more frequent in SMAT. Diminished bowel enhancement (OR = 20; p = 0.007) and paralytic ileus (OR = 16; p = 0.033) were independent findings suggesting life-threatening mesenteric occlusion. CONCLUSION: The ancillary CT findings occur with different frequencies in SMAT and SMVT. However, the independent findings indicating life-threatening mesenteric occlusion are diminished bowel wall enhancement and paralytic ileus.

OBJECTIVE: Clinical presentation and physical signs may be unreliable in the diagnosis of stercoral colitis (SC). This study evaluates the value of computed tomography (CT) in distinguishing fatal from non-fatal SC. MATERIALS AND METHODS: Ten patients diagnosed as SC were obtained from inter-specialist conferences. Additional 13 patients with suspected SC were identified via the Radiology Information System (RIS). These patients were divided into two groups; fatal and non-fatal SCs. Their CT images are reviewed by two board-certified radiologists blinded to the clinical data and radiographic reports. RESULTS: SC occurred in older patients and displayed no gender predisposition. There was significant correlation between fatal SC and CT findings of dense mucosa (p = 0.017), perfusion defects (p = 0.026), ascites (p = 0.023), or abnormal gas (p = 0.033). The sensitivity, specificity, and accuracy of dense mucosa were 71%, 86%, and 81%, respectively. These figures were 75%, 79%, and 77% for perfusion defects; 75%, 80%, and 78% for ascites; and 50%, 93%, and 78% for abnormal gas, respectively. Each CT sign of mucosal sloughing and pericolonic abscess displayed high specificity of 100% and 93% for diagnosing fatal SC, respectively. However, this did not reach statistical significance in diagnosing fatal SC. CONCLUSION: CT appears to be valuable in discriminating fatal from non-fatal SC.
